CONTAINER LID
TECHNICAL FIELD
[001] The present invention relates to a container lid having a function of maintaining an open state and, more specifically, a container lid having a function of maintaining an open state, in which the container lid is connected to a indication ring attached to a spout of a container, and a lid body for opening or closing a container opening is maintained while being folded out of the container opening as much as possible in a state in which the container opening is opened through the cover body.
TECHNICAL FUNDAMENTALS
[002] In general, a container containing liquid materials such as beverages, oils, paints, chemicals and the like, as well as mineral water, is formed with a spout to allow liquid materials to enter and exit.
[003] Furthermore, a container lid for opening or closing an opening of the container spout is provided on the spout in order to restrict the entry and exit of liquid materials.
[004] As shown in FIGS. 1 to 3, according to a general coupling structure between a nozzle N of a container B and a container lid 10, an M / S male thread is formed on an outer peripheral I / O surface of the nozzle N, which relatively stresses in container B, and an F / S female thread is formed on an internal peripheral surface I / S of the container lid 10 covering the nozzle N correspondingly in such a way that the container lid 10 can be screwed on or released from the container. nozzle N of container B.
[005] As described in Korean Patent Specification Report No. 10-1325850 (packaging container lid: hereinafter referred to as 'related technique 1') and Korean Patent Specification Report No. 10
Petition 870190111039, of 10/31/2019, p. 10/31
2/13
1038894 (packaging container lid: hereinafter referred to as 'related technique 2'), according to a container lid 10, which was recently developed, container lid 10 is still connected to the spout N of container B even when the nozzle N of container B is opened in order to eliminate the risk of loss of container lid 10 separated from nozzle N and the possibility of contamination by the entomes.
[006] Referring to FIGS. 1 and 2, the container lid 10 according to related techniques 1 and 2 includes a lid body 16 having a roof portion 12 and a sidewall portion 14 cylindrically formed below the ceiling portion 12 and formed in one internal wall thereof with an F / A female thread, a plurality of bridges 20 provided in a lower portion of the container body 16 and arranged in a radial direction, and an indication ring 18 integrally formed with one side of the container lid 10 through a hinge portion 22.
[007] Furthermore, a slit 24, which is cut in a horizontal direction, is formed in a vertical intermediate portion of the indication ring 18 below the hinge portion 22, and a lock portion 30 protrudes around a inner wall below slot 24.
[008] Thus, when opening the nozzle N of the container B by turning the lid body 16, the lid body 16 moves upwards, but the indication ring 18 disposed between a locking jaw C and a support jaw S / C, which are provided in the container B, is blocked by the locking jaw C without moving upwards so that the bridges 20 connected to a cutting portion 25 between the indication ring 18 and the cover body 16 are broken.
[009] In this way, it is possible to check whether the container lid 10 is open of container B based on the rupture of the bridges 20.
[0010] The aforementioned hinge portion 22 is connected to the indication ring 18 above the position of the slot 24, and the slot 24 is widened when
Petition 870190111039, of 10/31/2019, p. 11/31
3/13 the lid body 16 moves over the nozzle N of the container B, so that the connection state between the indication ring 18 and the lid body 16 can be maintained through the hinge portion 22.
[0011] Furthermore, according to related techniques 1 and 2, a cutting portion 26, which is cut through the cover body 16 and the indicating ring 18, is formed on both sides of the hinge portion 22 , and the cutting portion 26 is to provide a space to allow the hinge part 22 to be folded in and out and has a length of the limit position between the main body of the lid 16 and the indication ring 18 towards the cover body 16 located above indication ring 18.
[0012] Furthermore, the hinge portion 22 located in the cutting portion 26 has a small thickness from an internal side to an external side along the vertical intermediate portion between the cover body 16 and the indication ring 18, and a stepped portion 28, which is folded in the horizontal tangential direction to the lid body 16 and the indication ring 18 is formed at the position of the hinge portion 22, so that both sides of the stepped portion 28 in the horizontal direction project outwardly more than the surfaces of the cover body 16 and the indication ring 18.
[0013] As previously described, since both sides of the stepped portion 28 in the transverse direction of the stepped portion 28 protrude outwardly than the surfaces of the lid body 16 and the indication ring 18, a user may experience inconvenience by cause of the sense of difference when the user holds the container and a user's hand can be damaged when the container lid 10 is fastened with great force or when the user tries to open with excessive force while the contents between the container B and the lid of container 10 are hardened.
[0014] Above all, the hinge portion 22 of related techniques 1 and 2 has a stepped portion 28 so that the lid body 16 can be folded out of container B. However, once
Petition 870190111039, of 10/31/2019, p. 12/31
4/13 that the folded lid body 16 is eventually positioned to partially cover the opening of the container B by the influence of the elastic recovery force of the hinge portion 22 in the natural state, when the user wants to drink the drink through the spout N of the container B, the cover body 16 can interfere with the user so that the user has to intentionally bend out of the cover body 16.
[0015] In order to solve such inconvenience, as shown in FIG. 3, a technique is described in Korean Patent Specification Report No. 10-0981240 (hereinafter referred to as' related technique 3 '), in which a support 32 is provided in the hinge portion 22' in such a way that one end of the support 32 can be supported on an external wall of the container spout, thereby safely maintaining the open state of the lid body 16.
[0016] The position of the end of the aforementioned support 32 is located above the slot 24.
[0017] However, according to the related technique cited 3, in a state in which the opening of the container B is opened by the lid body 16 as shown in FIGS. 3 and 4, a portion of the indication ring 18 above the slot 24 is twisted from a fixed portion by the locking jaw C at both end positions PI of the slot 24, a position P2 of the cutting portion 26 formed in the ring of indication 18, and a position P3 where the cover body 16 is connected to the support, and the twisted length corresponds to a length dl to d3 obtained by connecting the “Pl to P3” as shown in FIG. 3.
[0018] That is, the aforementioned length dl-d3 of the twisted section includes the protruding length d3 of the support 32 and, finally, the twisted section dl-d3 can form a space greater than a marginal space D in a state in which the nozzle N of the container B is twisted against the outer wall, so that it is difficult to exert a supporting force on the support 32. In
Petition 870190111039, of 10/31/2019, p. 13/31
5/13 as a result, the lid body 16 is located in a position that covers the opening of the nozzle N of the container B because of the recovery force against the torsion.
[0019] In order to compensate for the presented problem, the position of the upper portion of the cutting portion 28 that leads to an upper side of the cap body 16 is formed up to a maximum upper position that does not interfere with the F / S female thread formed in the inner wall of the lid body 16, and the length of the support 32 must be large enough in that position.
[0020] However, the length extension of the support 32 may not allow the support 32 to stick strictly to the inner wall of the nozzle N of the container B, but allows the support 32 to be suspended on the inner wall of the nozzle N of the container B. In this way, the folding angle of the lid body 16 from the opening of the container B can be less than 90 °, which causes the user to take the action of moving the lid body 16 out of the opening of the container B by a hand to prevent interference.
[0021] Furthermore, in order to solve a problem like this, the related technique 3 has a T protrusion on the support 32 in such a way that the T protrusion can be suspended on the locking clamp C or on the M / S male thread formed at nozzle N of container B. However, protrusion T protrudes on an external surface of the lid body 16 in a state where the opening of nozzle N of container B is closed, so that protrusion T can interfere with the user when the user tries to open the opening of container B.
[0022] Additionally, in a state in which the cover body 16 is open, the connection positions Pl to P3 between the indication ring 18 on the upper side of the slot 24, the hinge portion 22, and the cover body 16 are forcibly twisted. As a result, a thin portion in the connection positions Pl to P3 can be easily broken by the physical force derived from the force for recovery from the twisted state and the supporting force of the
Petition 870190111039, of 10/31/2019, p. 14/31
6/13 support so that the cover body 16 can be lost.
DETAILED DESCRIPTION OF THE INVENTION
TECHNICAL PROBLEM
[0023] The present invention was made to solve the aforementioned problems of the related techniques, and an objective of the present invention is to provide a container lid having a function of maintaining an open state, which can be maintained in a stable state preventing damage or rupture the state of connection between a lid body and an indication ring, even when the container lid is continuously used, and can ensure that the lid body is located in a position completely outside a container nozzle opening during use from a container, such as to drink a drink.
TECHNICAL SOLUTION
[0024] In order to achieve the aforementioned objective, according to an aspect of the present invention, a container lid having a function of maintaining an open state is provided, the container lid including: an indication ring prevented from escaping from a container spout; a lid body threadedly coupled to an outer circumferential surface of the container spout; a hinge portion connecting the lid body and the indicating ring to each other in a partial section of a circumference of a cutting portion disposed between the lid body and the indicating ring; and a bridge connecting the lid body and the indication ring at an interval along a circumference of the cutting portion and is cut when the lid body is opened, where the hinge portion has opposite edge parts in the direction width adjacent to opposite cutting portions and pressed from the outside to an inside of the same, a folding guide groove formed to be integrally connected to the cover body, the indication ring and the hinge portion, and a portion bulge having a shape that stretches and stands out
Petition 870190111039, of 10/31/2019, p. 15/31
7/13 down from the bottom of the center towards the width of the center; and the indication ring includes a slot formed in a predetermined section of an intermediate part in a direction of its vertical height and a concave portion arranged in a position corresponding to the protrusion portion, adjacent to the protrusion portion still being spaced from it, and pressed down.
[0025] The folding guide groove can have a depth from an external side to an internal side of it, and form an inclined surface having a thickness gradually reduced from a center along the width of the hinge portion to an external edge of the even, thereby allowing a portion of the folding guide portion adjacent the lid body in a height direction in the opposite cutting portions having a relatively small thickness to be cut.
[0026] A torsional groove having a defined width, length and depth from an external side to an internal side of it can be formed on opposite sides of the indication ring provided on an upper side of the slot on opposite sides of the pivot, at least one torsional groove can be formed along the indication ring, and the torsional groove can have a predetermined gradient such that an upper end of each torsional groove in a longitudinal direction of the torsional groove is adjacent to the hinge portion and a lower end of each torsional groove is adjacent to a front end of the slot.
ADVANTAGE EFFECTS OF THE INVENTION
[0027] According to the aforementioned invention, the cover body in contact with the folding guide groove is integrally connected to the hinge portion and the indication ring portion provided on an upper side of the slot, and the portion of bulge is located less than
Petition 870190111039, of 10/31/2019, p. 16/31
8/13 a horizontal position of the slot, so that the protruding portion is supported on the container spout by the strong force in response to the twist recovery force of the twisted indication ring, which is continuously twisted at both ends of the slot in the articulation portion, and tension including torsion recovery force when the lid body is opened. In this way, the folding angle of the lid body with respect to the container spout can be increased, compared to related techniques. Therefore, the lid body can be stably located without interfering with the contents when the contents flow through the opening of the container spout.
[0028] Furthermore, a part of a relatively thin portion may be torn by the sloping surface of the folding guide groove described above, and the depth is formed inwardly so that the torn portion does not protrude outwardly. In this way, the torn portion can be prevented from being touched by a user's hand and there is an advantage in terms of aesthetics because the torn portion does not stick out.
