    TITLE
    STICK-SHAPED COSMETIC MATERIAL CONTAINER
    REFERENCE TO RELATED REQUESTS
    This application is based on and claims the benefit of the priority right of Japanese patent applications N ° 2017-083739, filed on April 20, 2017 and N ° 2017-119834, filed on June 19, 2017.
    STATE OF THE ART
    Field The present disclosure relates to a container for dispensing cosmetic material in the form of a stick which dispenses a cosmetic material in the form of a stick.
    Related Art [0002] As a dispenser for cosmetic material in the form of a rod in the related art, a container described in Japanese Unexamined Patent Application Publication No. 2001-218621 is known. Japanese Unexamined Patent Application Publication No. 2001218621 discloses a stick-shaped cosmetic material dispenser container which includes a tip cylinder housing a stick-shaped cosmetic material; and a main container body rotatably installed on the end cylinder. In the cosmetic stick dispenser container, the cosmetic stick shape appears or disappears from a notch formed in the tip cylinder since the main container body rotates relative to the tip cylinder.
    The notch in the tip cylinder is formed to extend from the front end of the tip cylinder, toward the rear, so that the stick-shaped cosmetic material is held by a front end portion, located on a side opposite to the notch in the radial direction, that is to say that the notch is formed at one end of end piece (ie T "front end") of the cylinder end cap, and the front end portion 35 is aligned with the notch (ie at the "opposite side" of the notch in the radial direction). Additionally, the stick-shaped cosmetic material is exposed from the notch of the tip cylinder when the cosmetic material faces or is aligned with the front end portion of the tip cylinder. When the stick-shaped cosmetic material does not exceed the tip cylinder, a portion of the stick-shaped cosmetic material which is exposed to the notch can be used. By using the portion of the stick-shaped cosmetic material which is exposed to the notch, as described above, the stable use of the stick-shaped cosmetic material has been attempted.
    SUMMARY In the container for dispensing cosmetic material in the form of a stick described above, the cosmetic material in the form of a stick is exposed from the notch of the end cylinder. As a result, when a force is applied to the stick-shaped cosmetic material against the front end portion side described above, since the stick-shaped cosmetic material is held by the front end portion, the material stick-shaped cosmetic can be used stably. However, when force is applied to the stick-shaped cosmetic material in a direction other than the front end portion side, there is a risk that the stick-shaped cosmetic material will be shaken and / or broken.
    In addition, in the container for dispensing cosmetic material in the form of a rod described above, the front end portion is arranged so as to surround the outer periphery of the cosmetic material in the form of a rod in the circumferential direction. Consequently, the front end portion, in concert with the stick-shaped cosmetic material, can enter the field of vision of a user of the stick-shaped cosmetic material dispenser container (ie blocks the view) when the the user applies makeup using the cosmetic material in the form of a stick. As the front end portion becomes a visual obstacle, it may be difficult for the user to see a surface (for example, the skin, etc.) where it is desired to apply the makeup and / or see the makeup at the as it is applied to the surface. As described above, the front end portion of the tip cylinder may enter the field of vision when a user applies makeup. As a result, the dispenser of cosmetic material in the form of a rod of the related art may be inconvenient for a user to employ, and there is a need to improve the ease of use.
    Consequently, a dispenser for cosmetic material in the form of a stick as will be described herein helps to reduce the breakage of a cosmetic material in the form of a stick for improved ease of use.
    According to one or more embodiments, it is provided with a dispenser of cosmetic material in the form of a stick, including: a cylindrical container including a front portion of the container and a rear portion of the container; a movable body having a male screw member; and a female screw member. In the cylindrical container, the rear container portion is mounted on the front container portion rotatably around an axis line and fixed in an axial direction. The movable body is adapted to move in the axial direction relative to the front portion of the container, holds a cosmetic material in the form of a rod, from a front end thereof, and includes a male screw on an outer periphery of this one. The female screw member which is not rotatable about the axis line with respect to the rear portion of the container, includes a female screw which is thread engaged with the male screw on an inner periphery thereof. Thread engagement action of a thread portion formed on the male screw and the female screw operates by relative rotation of the front container portion and the rear container portion so that the movable body advances and moves removes, and the stick-shaped cosmetic material appears or disappears at a front end of the front portion of the container in concert with the advancement or withdrawal of the movable body. The front portion of the container includes a holding portion which is slotted back from the front end thereof and holds the cosmetic material in the form of a stick. The cosmetic material in the form of a stick has a contact portion (comprising “opposite portions”) which faces and engages the holding portion. The stick-shaped cosmetic material also has an application portion which is opposite to the contact portion and which is configured so as to be exposed to the notched side of the holding portion, for applying makeup. The holding portion is formed so as to be tapered towards a front side of it. One portion of a concave portion and a convex portion extending in the axial direction extends to the holding portion on an inner peripheral surface of the front portion of the container. The other among the concave portion or the convex portion (ie the contact portion of the cosmetic stick) which extends in the axial direction and is held by said portion (ie by the concave or convex portion of the holding portion) . The contact portion is formed on an outer peripheral surface of the cosmetic material in the form of a stick and comprises a shape which is complementary (i.e. formed inversely) to a surface of the holding portion. When viewed from the front side (ie from the tip end), the stick-shaped cosmetic material is formed so as to be tapered away from a portion opposite to the holding portion (ie in s away from the contact portion), i.e. the width of the stick-shaped cosmetic material decreases as the distance from the contact portion increases, so as to be tapered at from the contact portion to the application portion. In addition, when viewed from the front side (i.e. from the tip end), a width of the contact portion of the stick-shaped cosmetic material is substantially the same as a width of the holding portion.
    According to one or more embodiments of the dispenser for cosmetic material in the form of a stick, the front portion of the container includes the holding portion which holds the cosmetic material in the form of a stick, and a portion among the concave portion and the convex portion extending in the axial direction, extends to the holding portion. In addition, the other portion (ie the contact portion of the cosmetic stick) from the concave portion or the convex portion extending in the axial direction and being held by said portion (the concave portion or the convex portion of the portion holding) is formed on the outer peripheral surface of the cosmetic material in the form of a stick. Consequently, as one of the concave portion and of the convex portion of the holding portion holds the other of the concave portion or of the convex portion of the stick-shaped cosmetic material, the stick-shaped cosmetic material can be held firmly by the holding portion through the convex portion being held by the concave portion. Therefore, the shaking of the stick-shaped cosmetic material can be reduced and thus the breakage of the stick-shaped cosmetic material can be prevented since the stick-shaped cosmetic material can be held more firmly by the concave portion holding the convex portion even when force is applied to the cosmetic material in the form of a stick, from almost any direction. In addition, the shape of the cosmetic material in the form of a rod, when viewed from the front side, is formed so as to be tapered away from the portion opposite to the holding portion, that is to say, when viewed from the tip end (ie the front side), the cosmetic material in the form of a stick is tapered from the contact portion towards the application portion. The width of the contact portion of the cosmetic material in the form of a stick when viewed from the front side is substantially the same as the width of the holding portion when viewed from the front side. By fixing the width of the holding portion so as to be substantially the same as the width of the cosmetic material in the form of a stick, it is possible to minimize any visual obstruction when applying the cosmetic material (i.e. by applying makeup). As a result, since the holding portion minimizes the visual obstruction of the field of vision, the user can more easily see where to apply the makeup. Therefore, the usability can be improved.
    In addition, the concave portion which extends in the axial direction is formed on the inner peripheral surface of the front portion of the container, the convex portion which extends in the axial direction and is held by the concave portion is formed on the outer peripheral surface of the cosmetic material in the form of a rod, and a width of a portion of the convex portion entering the concave portion when viewed from the front side may be greater than a width of an opening portion of the concave portion when viewed from the front side. Here, when a force is applied to the cosmetic stick-shaped material in a direction such that the cosmetic stick-shaped material tends to be detached from the concave portion, the outer surface of the convex portion is pressed against the inner surface of the concave portion, and thus the detachment of the convex portion from the concave portion and breakage can be reliably reduced. In other words, as the resistance of the stick-shaped cosmetic material to the force applied in a direction which tends to cause the convex portion to detach from the concave portion can be improved, the breaking of the stick-shaped cosmetic material can be more reliably reduced.
    According to one or more embodiments, it is possible to prevent the breaking of the cosmetic material in the form of a stick and improve the ease of use.

    DESCRIPTION OF THE EMBODIMENTS The embodiments of a dispenser for dispensing cosmetic material in the form of a stick will be described below with reference to the accompanying drawings. In the description of the drawings, the same elements or corresponding elements are designated by the same reference numerals and the description of the latter will not be repeated.
    First group of embodiments
    As shown in FIGS. 1 and 2, a container for dispensing cosmetic material in the form of a stick 1 (also designated herein as a “dispensing container for cosmetic” or “container”) according to a first embodiment, has the shape of a narrow cylindrical stick, elongated, such as a writing instrument, as a global form. In addition, the cosmetic dispenser container contains a cosmetic material in the form of a stick M (also referred to herein as a "cosmetic stick M") covered by a cap Cl. In the cosmetic dispenser container 1, a user can apply makeup using the cosmetic stick M immediately when the cap C1 is removed. As an example, the cosmetic stick M includes eyebrow makeup and the cosmetic dispenser container 1 is an eyebrow makeup dispenser container.
    For example, the cosmetic dispenser container 1 includes a cylindrical container 2 which includes a nozzle cylinder 3 which constitutes a front portion of the container or a dispensing portion and a main container body 4 constituting a rear portion of the container ; a movable body 5 which is housed in the end cylinder 3; a spring member 6 which is housed in the main container body 4; a female screw member 7 which is housed in the spring member 6; a brush portion 8 which is provided on the rear side of the main container body 4; and a cap C2 which covers the brush portion 8 and is detachably provided with the main container body 4.
    In this specification, the "axis" or "axis line" indicates a line extending between a rear end and a front end of the cosmetic dispenser container 1 and may extend to a center of the cosmetic dispenser container 1, according to one or more embodiments. "Axial direction" indicates a front-rear direction or an orientation along the axis or the axis line. In addition, the dispensing direction of the stick cosmetic M is fixed as before (the advancing direction) and the direction of withdrawal of the stick cosmetic M is fixed as the rear (withdrawal direction).
    As illustrated in FIGS. 3A and 3B, the end cylinder 3 is formed so as to have as a whole, a shape of thin elongated round rod. The tip cylinder 3 is formed in a cylindrical stepped shape provided with a stepped portion 3a whose diameter increases towards the front side (ie towards a tip end) on the outer peripheral surface in the vicinity of the center in the axial direction. A portion on the rear side (ie towards a connection end) from the stepped portion 3 a is formed as a cylindrical portion 3 s (also called a “rear portion 3s” or “connection portion 3s”) . A portion on the front side of the stepped portion 3a is formed as an inclined surface 3c (also called a "front portion 3c" or "application portion 3c") which has a diameter which decreases towards the front side ( ie towards the tip end) on the outer peripheral surface of the tip cylinder 3.
    A support, for example a portion of 3d holding, which holds or supports the cosmetic stick M is provided on the front side of the tip cylinder 3 from the inclined surface 3c, projecting along the axis of the main body. The shape of the holding portion 3d is formed such that a side surface of the end cylinder 3 is notched. A notch line (ie a contour or a contour of the notched region of the nozzle cylinder) forms an outlet of the nozzle cylinder 3. In the holding portion 3d, a side surface of the nozzle cylinder 3 is notched and the holding portion extends to the rear side from a 3h front end of the end cylinder 3. The 3d holding portion (also referred to herein as "the support" or "held member") includes a contoured guide for engaging a contoured contact surface of the cosmetic stick M. The contoured guide may include a concave portion (having a U-shaped cross section) or a convex portion (having a T-shaped cross section ), for example. The 3d holding portion will be described in detail below.
    The connection portion 3s of the end cylinder 3 is cylindrical and inserted into the spring member 6 having a cylindrical shape. The application portion 3c is exposed towards the outside, that is to say that the application portion 3c protrudes outside the main body 4. An uneven annular portion 3b engaged with the spring member 6 in a rotary manner and fixed in the axial direction, is formed on the outer peripheral surface of the end cylinder 3 on the rear side. That is to say, the annular portion 3b is coupled with the spring member 6 to allow rotation relative to the spring member 6 by blocking movement in the axial direction relative to the spring member 6.
    As illustrated in FIGS. 2 and 4, the spring member 6 is formed so as to be substantially cylindrical. A convex annular portion 6j engaged with the uneven annular portion 3b of the end cylinder 3 in the axial direction is formed on the inner peripheral surface of the spring member 6 at the rear side. The spring member 6 has a function of alleviating the impact on the interior of the cosmetic dispensing container 1 and of protecting the cosmetic dispensing container 1 against an action of an external force, for example if the cosmetic dispensing container 1 is dropped, shaken or knocked against a rigid surface.
    A front end 6m of the spring member 6 is brought into contact with the stepped portion 3a of the end cylinder 3 from the rear side thereof. The spring member 6 includes: a flange portion 6a provided at the front side in the axial direction thereof; a front-side cylindrical portion 6b located at the front side of the flange portion 6a; and a rear-side cylindrical portion 6c located at the rear side of the flange portion 6a. A hemispherical projection 6d for mounting the cap C1 is formed on the outer peripheral surface of the front-side cylindrical portion 6b. For example, three protrusions 6d are formed and these three protrusions 6d are arranged in the circumferential direction of the spring member 6 at equal intervals.
    The rear-side cylindrical portion 6c of the spring member 6 includes: a convex annular portion 6e formed on the outer peripheral surface thereof; and a spring portion 6f located on the rear side of the convex annular portion 6e. The spring portion 6f is a resin spring configured so as to stretch and compress in the axial direction. The spring portion 6f is defined by a slot 6g formed in the main body portion 6h, which extends in a spiral shape along the circumferential surface, providing an opening between an interior and an exterior of the spring. The spring portion 6f can be stretched or compressed so as to attenuate an impact caused when an external force is applied.
    The flange portion 6a is engaged with the concave annular portion 4a formed at the front end of the inner peripheral surface of the main container body 4. In addition, the convex annular portion 6e is engaged with the concave annular portion 4b located on the rear side of the concave annular portion 4a, in the axial direction. The main container body 4 is mounted on the end cylinder 3 so as to be rotatable relative to the end cylinder 3, around the axis line and to be fixed (or "stationary") in relation to the end cylinder. end piece 3, in the axial direction. In addition, a projecting annular portion 4c with which the rear end of the spring member 6 is brought into contact; and a thumb wheel 4d which is engaged with a female screw member 7 in the direction of rotation at the rear side of the projecting annular portion 4c, are provided inside the main container body 4 and the rear side of the spring member 6 .
    As illustrated in FIGS. 2 and 5, the female screw member 7 is formed in a substantially cylindrical shape. A projection 7a which is engaged with the wheel 4d of the main container body 4 in the direction of rotation, extends in the axial direction and is arranged in parallel along the circumferential direction, is provided on the rear side of the peripheral surface. outside of the female screw member 7. Thanks to this engagement of the projection 7a with the knob 4d in the direction of rotation, the female screw member 7 is provided in a rotary (non-rotary) manner in synchronization with respect to the body main container 4.
    The female screw member 7 is formed, for example, of polyacetal (POM). A flange portion 7b which is brought into contact with the rear end of the end cylinder 3 from the rear side; and a concave annular portion 7c and a convex annular portion 7d which are engaged with the end cylinder 3 in the axial direction are provided on the outer peripheral surface of the female screw member 7 at the front side of the projection 7a. The concave annular portion 7c is engaged with a convex annular portion 3t formed on the inner peripheral surface of the end cylinder 3 in the axial direction; and the convex annular portion
    7d is engaged with a concave annular portion 3v formed on the inner peripheral surface of the end cylinder 3 in the axial direction. In addition, a female screw portion 7e which functions as a female screw constituting a threading portion 10 is provided on the inner peripheral surface of the female screw member 7 on the rear side and a rear end portion of the movable body. 5 is engaged by threading with the female screw portion 7e.
    As illustrated in FIGS. 2 and 6, the movable body 5 is a support for cosmetic material in the form of a stick which supports the cosmetic in a stick M by the front end thereof. The movable body 5 is arranged in the end cylinder 3 and the female screw member 7 and extends in the axial direction. The movable body 5 is provided movably relative to the end cylinder 3 in the axial direction and as a whole has the shape of a round rod. The movable body 5 is formed from polybutylene terephthalate (PBT).
    The movable body 5 includes a threaded projection 5a, which functions as a male screw constituting the other thread portion 10, on the outer peripheral surface of the rear end portion thereof. The movable body 5 includes a portion of axis body in the shape of a round rod 5b situated at the front side of the threaded projection 5a; and a support portion 5c which is provided on the front end of the movable body 5 and supports the rear end portion of the stick cosmetic M.
    The support portion 5c includes a base 5g with which the rear end surface of the cosmetic stick M is brought into contact; first two support pieces 5d which support the rear end portion of the cosmetic stick M; and a second support piece 5f. The first support pieces 5d and the second support piece 5f are provided along the outer peripheral surface of the base 5g and protrude forward. A pair of two first support pieces 5d protrude from the base 5g and a rib 5e extending in the axial direction is provided in the inner surface of each of the first support pieces 5d.
    The second support piece 5f is curved into a curved shape so as to partially surround the cosmetic stick M on the side opposite two first support pieces 5d of the movable body 5 in the radial direction. The rear end portion of the cosmetic stick M is supported by being installed in a region between the support pieces, which comprise the first support pieces 5d and the second support piece 5f.
    Next, the cosmetic stick M and the end cylinder 3 will be described in detail with reference to FIGS. 7 and 8. As described above, the end cylinder 3 (or dispensing portion) includes the holding portion 3d (also referred to herein as "support" or "holding member") which holds the cosmetic in stick M at the front end of it (ie one end of application of the cosmetic in stick M). The holding portion 3d is formed such that a side surface of the end cylinder 3 is notched in the radial direction (ie notched from the side) and also notched from the front end 3h (ie notched from the tip end) of the tip cylinder 3 to the rear side.
    The 3d holding portion is formed so as to narrow towards the front side (towards the end of the end piece). The holding portion 3d is formed so as to include the end surface of the front end of the end cylinder 3 which is notched from the front end of the inclined surface 3c. The holding portion 3d includes a first curved portion 3e which extends on one side (lower side in FIGS. 7 and 8) of the end cylinder 3 in the radial direction from the inclined surface 3c and is curved ; an extension portion 3f which extends substantially in the axial direction from the front end of the first curved portion 3e; and a second curved portion 3g which is curved on one side of the end cylinder 3 in the radial direction from the front end of the extension portion 3f.
    The first curved portion 3e is curved on one side in the radial direction from the inclined surface 3c and is gradually curved in the axial direction to one side, in the radial direction. The lengths of the first curved portion 3e, of the extension portion 3f and of the second curved portion 3g (holding portion 3d) in the axial direction are respectively in a range of 3 mm to 15 mm. In addition, the front end 3h of the second curved portion 3g is a portion of the end cylinder 3 to which the cosmetic stick M appears or disappears (i.e. is exposed or hidden). The second curved portion 3g is progressively curved on one side in the radial direction from the extension portion 3f towards the front end 3h. The first curved portion 3e, the extension portion 3f, the second curved portion 3g and the front end 3h defines a contour of the outlet of the dispensing portion (the end cylinder 3), for dispensing the cosmetic in sticks Mr.
    As shown in FIG. 8, pairs of first curved left and right portions 3 e, left and right extension portions 3 f and second curved left and right portions 3 g are provided around the cosmetic in stick M when viewed from the front side (ie from the application tip end). The left and right extension portions 3f and the second curved portions 3g form a pair of projections which extend along the edge portions of the support and which project towards the cosmetic in stick M, so that the support (or the holding portion 3d) has a substantially U-shaped cross section. When viewed from the front side (ie from the end of the end piece), a concave portion 3j is formed of a pair of interior surfaces of the second curved portion 3g and the inner surface of the front end 3h. The concave portion 3j extends in the axial direction on the inner peripheral surface of the end cylinder 3 and extends to the holding portion 3d. In FIG. 8, the profiled guide of the holding portion 3d (support) comprises the pair of projections which form the concave portion 3j. The projections include end surfaces, corresponding to the left and right extension portions 3f, which are configured so as to contact the profiled contact surface of the cosmetic in stick M. A central portion recessed in the profile guide, corresponding to the inner surface of the front end 3h is stepped and set back relative to the end surfaces 3f of the projections. The recessed central portion includes a substantially flat surface and the projections extend perpendicular to the substantially flat surface. Thus, the profiled guide extends along a profiled support surface in which the end surfaces 3f of the projections include stepped side portions which are stepped relative to a central portion 3j (for example the central portion in withdrawal) and located on each side of the central portion. The stepped side portions include substantially flat portions. The substantially flat portions of the recessed central portion and stepped side portions extend parallel to the axis of the main body, and the pair of projections includes wall surfaces, each located between the central portion and one of the surfaces from the side stepped (for example the pair of interior surfaces of the second curved portion 3 g), which extend substantially perpendicular to the central portion.
    In the holding portion 3d, the cosmetic stick M extends to the front side from the first curved portion 3e and is curved on a front side of the extension portion 3f in the radial direction. When viewed from the front side (i.e. from the tip of the application tip), as shown in FIG. 8, the cosmetic stick M has an opposite portion M3 which faces the holding member 3d, and is configured to engage the holding member 3d. The cosmetic stick M extends in a tapered shape from the 3d holding member.
    In FIG. 8, the cosmetic stick M includes a top Ml; a pair of left and right curved portions M2 on both sides, which extend from the top Ml to the extension portion 3f; a pair of opposite portions M3 as described above; and a convex portion M4 protruding from a region between the pair of opposite portions M3. The top M1 is located at a point furthest from the extension portion 3f. The curved portions M2 are formed so as to have a shape along the outer periphery of an ellipse. The opposite portions M3 are located at the ends of each curved portion M2, opposite the top Ml. The cosmetic stick M includes an application surface, and the aforementioned profiled contact surface opposite the application surface. The application surface comprises the curved portions M2 and the apex Ml, and the profiled contact surface comprises the opposite portions M3 and a surface of the convex portion M4. Consequently, the cosmetic stick M shrinks from a portion adjacent to the profiled contact surface M3, M4 towards the top Ml of the application surface M2, Ml.
    The convex portion M4 is a portion held by the concave portion 3j and protruding into the concave portion 3j of the region between the pair of opposite portions M3. In addition, a space is formed between the cosmetic stick M and the holding portion 3d (between the concave portion 3j and the convex portion M4). It is desirable that this space be as small as possible. Due to this space, the shaking of the stick cosmetic M is reduced even when a force is applied to a side surface of the stick cosmetic M during use, and thus the stick cosmetic M is less likely to to be broken.
    When viewed from the front side, where the width of the opposite portions M3 of the cosmetic stick M is fixed with a width A (or simply A) and the width of the front end 3h of the holding portion 3d (or support) is fixed with a width B (or simply B), the width A is substantially the same as the width B. The width A indicates the maximum width of the front end of the cosmetic stick M when the cosmetic stick M is seen from the front side; and width B indicates the maximum width of the front end 3h of the 3d holding portion when the 3d holding portion is viewed from the front side. Specifically, the width B of the pair of second curved portions 3g when viewed from the side having is substantially the same as the width A of the opposite portions M3 of the cosmetic in stick M. As for the expression “substantially the same”, the difference between the width A of the cosmetic stick M and the width B the holding portion 3d (for example, the value of BA or AB) can be between 0.0 mm and 1 mm, and preferably between 0.0 mm and 0 , 6 mm. In addition or in the alternative, the difference between the widths of the cosmetic in stick M and of the holding portion 3d may be within approximately 25%, and preferably within approximately 10 to 15%, for example by relative to the width of the cosmetic stick M or relative to the width of the holding portion 3d. The width B can measure within a range of approximately 1 to 3 mm, preferably within a range of approximately 2 to 3 mm, for example 2.5 mm. The width A can measure within a range of 1 to 3 mm, preferably within a range within about 2 to 3 mm, for example 2.5 mm. In one or more alternative embodiments, the width A of the cosmetic stick M is greater than the width B of the front end 3h of the holding portion 3d.
    In the cosmetic dispenser container 1 described above, a method will be described, for dispensing or removing the cosmetic stick M so that the movable body 5 advances or retracts and the cosmetic stick M appears or disappears. First, referring to FIG. 2, when the cap C1 is removed and the main container body 4 is rotated relative to the tip cylinder 3 in one direction (for example, clockwise), then the main container body 4, the member of spring 6, and the female screw member 7 rotates synchronously, and the movable body 5 advances towards the end cylinder thanks to the thread engagement engagement of the thread portion 10 comprising the female screw portion 7e of the female screw member 7 and the threaded projection 5a of the movable body 5. The cosmetic stick M appears from the front end 3h of the end cylinder 3 thanks to the advancement of the movable body 5 so that the cosmetic stick M is suitable for dispensing. In addition, when the main container body 4 is rotated relative to the end cylinder 3, in a direction opposite to said direction (for example, counterclockwise), the main container body 4, the member spring 6 and the female screw member 7 rotates synchronously and the movable body 5 retracts by virtue of the threading engagement action of the thread portion 10. In this way, the cosmetic stick M supported by the movable body 5 retracts away from the front end 3h.
    As described above, according to the cosmetic dispenser container 1 of this embodiment, the nozzle cylinder 3 includes the 3d holding portion which holds the cosmetic in stick M, and the concave portion 3j s' extending in the axial direction extends to the holding portion 3d as illustrated in FIGS. 7 and 8. In addition, the convex portion M4 which extends in the axial direction and is held by the concave portion 3j is formed on the outer peripheral surface of the stick cosmetic M.
    Consequently, since the convex portion M4 of the cosmetic stick M is held by the concave portion 3j of the holding portion 3d, the cosmetic stick M can be held substantially rigidly by the holding portion 3d thanks to the concave portion 3j holding the convex portion M4. Consequently, the cosmetic stick M can be held substantially rigidly by the concave portion 3j holding the convex portion M4 even when a force is applied to the cosmetic stick M in any direction. Therefore, the shaking of the cosmetic stick M is reduced so that the risk of breaking the cosmetic stick M can be reduced substantially.
    In addition, the shape of the cosmetic stick M when viewed from the front side is formed so as to be tapered as and when increasing a distance from the opposite portions M3, and the width A of the opposite portions M3 cosmetic stick M when viewed from the front side is substantially the same as the width B of the holding portion 3d when viewed from the front side. Consequently, the holding portion 3d at the time of applying the makeup is less likely to block the field of vision since the width B of the holding portion 3d is substantially the same as the width A of the cosmetic in stick M.
    As the 3d holding portion does not block the field of vision, a user can better see the application surface and apply makeup more easily. Therefore, the usability can be improved. Second group of embodiments
    Next, a cosmetic dispenser container according to a second group of embodiments will be described with reference to FIG. 9. FIG. 9 illustrates an end cylinder 23 and a cosmetic material in the form of stick P (also designated herein as "cosmetic in stick P") of the cosmetic dispenser container according to the second embodiment when viewed from the front side. The second embodiment differs from the first embodiment from the point of view of the configurations of the end cylinder 23 and of the cosmetic stick P. Hereafter, some of the characteristics common to those of the cosmetic dispensing container according to the first embodiment will not be described. The end cylinder 23 includes a holding portion 23d which holds the cosmetic stick P, and a concave portion 23j which extends in the axial direction is formed on the holding portion 23 d. A convex portion P4 which extends in the axial direction is formed on the outer peripheral surface of the cosmetic stick P, and is held by the concave portion 23j of the holding portion 23d. Since the convex portion P4 of the cosmetic stick P is held by the concave portion 23j of the holding portion 23d, the cosmetic stick P can be held firmly by the holding portion 23 d by holding the convex portion P4 by the concave portion 23j.
    The shape of the convex portion P4 when viewed from the front side and the shape of the concave portion 23j when viewed from the front side both follow the shape of an isosceles trapezoid having an upper base which is shorter than the lower base of it. The convex portion P4 includes a bottom P41 which extends in the width direction of the stick cosmetic P; and a pair of outer surfaces P42 which extend to the top side M1 of the cosmetic stick P from the ends of the bottom P41 in the width direction. The underside P41 and the outer surfaces P42 are formed so as to be flat. The concave portion 23j has a shape similar to that of the convex portion P4.
    In FIG. 9, the profiled guide of the support comprises the concave portion 23j and a pair of projections having end surfaces corresponding to the left and right extension portions 3f, which are configured to contact the profiled contact surface M3, P4 of the cosmetic in stick P. The concave portion 23j includes: a flat surface 23j 1 opposing (ie facing) the underside P41 of the cosmetic in stick P; and a pair of interior surfaces 23j2 which extend from each end of the flat surface 23j 1 in the width direction, towards the top side Ml of the cosmetic in stick P. A width D of a portion of the portion convex P4 entering the concave portion 23j is greater than a width E of an opening portion 23j3 of the concave portion 23j. Here, the “width of the portion of the convex portion entering the concave portion” indicates a portion of the convex portion P4 entering the concave portion 23j, which is a portion located on a deeper side of the concave portion 23j than the opening portion 23d3. The opening portion 23j3 indicates an edge portion of the concave portion 23j. Consequently, the protrusions include interior side surfaces 23j2 between the end surfaces 3f and the recessed central portion (the flat surface 23j 1), and the interior side surfaces 23j2 are closer to each other. toward the end surfaces 3f than toward the recessed central portion 23j 1. In addition, the projections extend substantially perpendicular to a substantially flat surface of the recessed central portion 23j 1, and the projections are more wider towards the end surfaces 3f than towards the recessed central portion 23j 1. The protrusions include outer side surfaces 3i opposite the inner side surfaces 23j2, which are oriented substantially perpendicular to the portion central recessed 23d 1.
    As described above, in the cosmetic dispenser container according to the second embodiment, the concave portion 23j which extends in the axial direction is formed on the inner peripheral surface of the end cylinder 23; and the convex portion P4 which extends in the axial direction and is held by the concave portion 23j is formed on the outer peripheral surface of the cosmetic in stick P. The width D of the portion of the convex portion P4 entering the concave portion 23j when seen from the front side, is greater than the width E of the opening portion 23j3 of the concave portion 23j when viewed from the front side.
    Consequently, when a force is applied to the cosmetic stick P in a direction (upward direction in FIG. 9) of detachment of the cosmetic stick P from the concave portion 23j, the detachment of the convex portion P4 from the concave portion 23j and the breakage of the cosmetic stick P can be reliably reduced by bringing the outer surfaces P42 of the convex portion P4 into contact with the inner surfaces 23j2 of the concave portion 23j. In other words, the resistance of the P-stick cosmetic to the force applied in the direction of detachment of the convex portion P4 from the concave portion 23j can be increased, and thus the breakage of the P-stick cosmetic can be further reduced by reliably.
    By forming the interior surfaces 23j2 of the concave portion 23j and the exterior surfaces P42 of the convex portion P4 so as to be flat, the region where the exterior surfaces P42 are in contact with the interior surfaces 23j2 can be increased. Therefore, breakage of the P-stick cosmetic can be further reliably reduced since the tension applied to the P-stick cosmetic can be reduced.
    Embodiments of the cosmetic dispenser container have been described above, but the embodiments are not limited to the embodiments described above and modifications can be made within the scope not modifying the major ones. lines described in the claims. That is to say, the shape and the mode of arrangement of each component constituting the cosmetic dispenser container 1 can be modified as appropriate within the scope not modifying the broad lines described above.
    In the embodiment described above, the example in which the cosmetic dispenser container includes the holding portion 3d which has the concave portion 3j and the stick cosmetic M which has the convex portion M4 has been described . However, as shown in FIG. 10, the cosmetic dispenser container may include a holding portion 13d which has a convex portion 13j and a cosmetic material in the form of stick N (also referred to herein as "the cosmetic in stick N") which has a concave portion N4 instead of the holding portion 3d and the cosmetic in stick M. Similarly, when the width A of the opposite portion M3 of the cosmetic in stick N when viewed from the front side, is substantially the same as the width B of the portion 13d holding when viewed from the front side, the same effects as those of the embodiments described above are obtained. Thus, the profiled contact surface of the cosmetic stick N comprises a groove (for example, the concave portion N4), and the profiled support surface of the support 13d comprises a projecting tongue (ie the convex portion 13j) which extends along a central portion of the support 13d and protruding into the groove N4 of the cosmetic stick N, so that the support 13d has a cross section substantially in the form of a T. Thus, the profiled guide extends along a profiled support surface comprising a central portion (for example, a top surface of the convex portion 13j) extending parallel to the axis of the main body, and stepped side portions (facing the opposite portion M3 cosmetic stick N) which are stepped relative to the central portion and located on each side of the central portion. The stepped side portions are recessed from the central portion of the profiled support surface of the dispenser, so that the support has a substantially T-shaped cross section.
    In the embodiment described above, as illustrated in FIG. 9, the end cylinder 23 which includes the concave portion 23j having the flat interior surfaces 23j2; and the cosmetic stick P which includes the convex portion P4 having the outer surfaces P42 has been described. However, as shown in FIG. 11, an end cylinder 33 which includes a concave portion 33j having curved interior surfaces 33j2; and a R-shaped cosmetic material R (also referred to herein as "R-shaped cosmetic") which includes a convex portion R4 having curved outer surfaces R42 can be used.
    Even in the cosmetic stick R and the end cylinder 33, the width D of the portion of the convex portion R4 entering the concave portion 33j when viewed from the front side is greater than the width E of a opening portion 33j3 of the concave portion 33j when viewed from the front side. Consequently, when a force is applied to the cosmetic stick R in a direction of detachment of the cosmetic stick R from the concave portion 33j (upward direction in FIG. 11), the outer surfaces R42 of the convex portion R4 are brought into contact with the interior surfaces 33j2 of the concave portion 33j. Consequently, since the detachment of the convex portion R4 from the concave portion 33j is reduced more reliably, and the resistance of the cosmetic stick R to the force applied in the direction of the convex portion R4 being detached from the concave portion 33j can be improved, breakage of cosmetic stick R can be reduced more reliably. As shown in the example in FIG. 11 and the example of FIG. 9, the shape of the inner surface of the concave portion and the shape of the outer surface of the convex portion can be changed as appropriate. FIG. 12 shows a holding portion (or support) 43d and a cosmetic stick S, according to another group of embodiments, as seen from the end before 3 o'clock. The cosmetic stick S can have a cross section which is substantially oval, having a length L and a width G. The length L can be within a range of 4 to 5 mm approximately, for example a length L of approximately 4.6 mm. The width G can be within a range of about 1 to 2 mm, preferably within a range of about 1.5 to 2 mm. The substantially oval cross section is truncated at one end S1 opposite the support 43d, the truncated end SI forming a substantially flat surface S2. The cosmetic stick S comprises an outer surface S42, including a contact surface S4 for contacting the support 43d and an application surface S3 opposite the contact surface S4. The application surface S3 of the cosmetic stick S includes the substantially flat surface S2. The shape of the support 43 d can be substantially V-shaped, U-shaped or similar, in order to conform to the shape of the contact surface S4 of the cosmetic in stick S. The support 43d has an interior surface 43j2 which engages the surface contact S4 of the cosmetic stick S, and an outer surface 3i opposite the inner surface 43j2. A thickness of the support 43 d is defined by a distance between the interior surface 43j2 and the exterior surface 3i. The support 43d has a valley portion 3k and ends 3m near the extension portions 3f. The thickness 3nl of the support 43d at the ends 3m is smaller than the thickness 3n2 at the valley portion 3k. The internal surface 43j2 comprises substantially flat surfaces between the valley 3k and the ends 3m. The thickness 3nl can be within a range of 0.5 to 0.8 mm approximately, preferably between 0.6 and 0.7 mm approximately. The thickness 3n2 can be within a range of about 0.5 to 2 mm, preferably within a range of about 1 to 1.3 mm. The support 43d has a width F which can be within a range of approximately 2 to 3 mm, preferably within a range of approximately 1.5 to 2.5 mm. In certain embodiments, the width F of the support 43j2 is substantially equal to the width G of the cosmetic in stick S, for example, a difference between the widths F and G is within 1 mm, or within 25%, preferably within 10-15%, relative to the largest width among the width F of the support and the width G of the cosmetic in stick S. According to one or more embodiments, the portion of the support 43d which is configured for engaging the cosmetic stick S comprises at least one flat surface. According to one or more embodiments, the portion of the support 43 of which is configured to engage the cosmetic stick S comprises at least two flat surfaces.
    In addition, in the embodiment described above, as illustrated in FIG. 8, the cosmetic stick M in which the top Ml, the curved portion M2 and the opposite portion M3 have an elliptical shape has been described, but the shape of the cosmetic stick M can be modified as appropriate. For example, portions corresponding to the vertex portion Μ1, the curved portion M2 and the opposite portion M3 may have a triangular shape, a parabolic shape, an oval shape, an arc shape, a polygonal shape and / or the like. so as to be tapered as a distance from the M3 portion increases. Consequently, the shape of the cosmetic stick is not limited.
    In addition, in the embodiment described above, as illustrated in FIG. 7, the example in which the cosmetic dispenser container includes the 3d holding portion including the first curved portion 3e, the extension portion 3f and the second curved portion 3g has been described. However, the shape of the 3d holding portion can be changed as appropriate. In addition, the lengths and shapes of the first curved portion 3e, the extension portion 3f and the second curved portion 3g can be changed as appropriate. Particularly, according to the embodiment described above, even when the holding portion 3d extends lengthwise in the axial direction, the holding force of the cosmetic stick M can be obtained more reliably, and thus it is particularly effective for the holding portion 3d to extend lengthwise (for example, a case where the length of the holding portion 3d in the axial direction is 15 mm or more).
    In addition, in the embodiment described above, the cosmetic dispenser container 1 including the container 2 which includes the end cylinder 3 and the main container body 4; the movable body 5; the spring member 6; the female screw member 7; the brush portion 8; and caps C1 and C2 have been described. However, for example, the brush portion 8 and the cap C2 may not be provided in the cosmetic dispenser container according to one or more embodiments. In addition, the shapes, sizes and materials of the container 2, the movable body 5, the spring member 6, and the female screw member 7 can be changed as appropriate.
    In addition, in the embodiments described above, the example has been described, in which the cosmetic stick M comprises eyebrow makeup and the cosmetic dispenser container 1 is an eyebrow makeup dispenser container . However, the dispenser for cosmetic material in the form of a stick according to one or more embodiments can be applied to various cosmetic materials in the form of a stick such as eyeliners, correcting pencils and lip pencils.
    It is understood that all the aspects, advantages and characteristics described in the present are not necessarily achieved by, or included in, any particular exemplary embodiment. Indeed, having described and illustrated various examples herein, it should be apparent that other examples can be changed in terms of arrangement and detail. We claim all modifications and variations understood in the spirit and scope of the material claimed herein.
