    DESCRIPTION

    Cap with articulated placket

    The present invention relates to a cap for the closure of containers for liquids, 5 which has advantageous characteristics over what is currently known.

    The cap object of the present invention is used in containers for liquids, in particular food liquids, beverages, such as water, and others. A problem that all plugs must solve is that of tightness. This problem is especially noticeable in the simplest type caps and, especially, in plastic bottle caps whose manufacturing process causes the bottlenuts to have very large dimensional tolerances. In these cases, the usually adopted solution is to provide a seal attached to the neck of the bottle that ensures tightness before the first opening. However, the problem of maintaining minimum levels of tightness after the first opening still persists. For this, it is usually adopted as a solution to have screw closures on the cap. Even so, in the case of large dimensional tolerances in the neck of the bottle, the level of tightness obtained only with the thread is not optimal for the needs of the user.
     twenty
    It is an objective of the present invention to provide a solution to the aforementioned problems, disclosing means that allow to improve the sealing of the plastic caps, especially in the case of simple caps and / or intended for bottles with large dimensional tolerances.
     25
    The applicant's long experience in the design, manufacture and marketing of caps of the aforementioned type, has allowed him to develop a new cap, object of the present invention, which is characterized by achieving with a limited number of constituents of reduced mass, excellent characteristics Watertight closure of the different areas of the cap and all this together with very practical means of assembly and closure. 30

    The cap object of the present invention can be of vertical opening, that is, it is removed by stretching it in the vertical direction (ie, the direction of the main axis of the neck), which allows, if desired, to dispense with type closures. thread, which in turn allows smaller caps. 35

    More in particular, the present invention discloses a plastic bottle cap of the type that comprises a cap with means for attaching to the neck of the bottle and further comprising a sealing membrane of the mouth of the bottle and because the cap It also has an articulated placket in its upper area for opening the cap. 5

    Preferably, said means for attaching to the neck of the bottle consist of a projection or projections intended or intended to interfere, in the direction of the main axis of the bottle neck, with conjugate projections of the neck. More preferably, the projection or projections consists of a circular projection. The provision of this type of closure by 10 dimensional interference is made possible by the existence of the sealing membrane.

    When the membrane is arranged in the cap itself, the tightness is also ensured after the first use, since the sealing means is not destroyed before the first opening. It allows its detachment from the neck of the bottle by pulling a flap, 15 in the vertical direction opposite to said bottle. The placket is preferably located in the central part of said stopper. Preferably, the placket has a precut at its perimeter of attachment to the cap as well as a hinge that allows the said placket to be folded out by pulling the groove and cutting the precut elements.
     twenty
    The present invention allows numerous embodiments of the membrane responsible for sealing the passage of liquid. Preferably, said membrane is constituted by an independent part of the hood which is arranged under said upper area of the hood. More preferably, said membrane has a circular main body intended to completely cover the mouth of the bottle. 25

    In a first embodiment the membrane the membrane is a bi-injected piece in two materials, the main body being manufactured in a material and presenting a circular crown-shaped area in another material softer than that of the main body, said area being in circular crown shape intended to come into close contact with the uppermost wall 30 of the bottle neck. The bi-injection process makes it possible to have two materials in one piece: a first material covering the inner horizontal surface of the cap and a second softer material with respect to the first material that allows to obtain a tight connection between the cap and the bottle, when This second ring-shaped material is located in the area of contact with the uppermost surface of the neck or neck of the bottle.

    In a second embodiment, the inner membrane has a flexible trumpet-shaped projection that folds when closed by sealing the liquid outlet, which prevents the passage of liquid through the inner wall of the bottle neck. This second embodiment has an advantage since it allows the sealing of the cap by admitting 5-dimensional tolerances on the inner surface of the neck of the even larger bottle.

    An additional advantage of the cap object of the present invention is that it is possible to reuse the cap once the cap has been torn, closing the bottle again.
     10
    An advantage of being of plastic material unlike other materials such as metal is the reduction in the risk of cutting for the user in the process of opening the bottle cap.

    The plastic bottle cap of the present invention comprises a cap with means for attaching to the neck of the bottle characterized in that the cap further comprises a sealing membrane of the mouth of the bottle and because the cap also has an articulated placket in its upper zone for opening the cap.

    Preferably said means for attaching to the neck of the bottle consist of a projection 20 or projections intended or intended to interfere, in the direction of the main axis of the bottle neck, with conjugate projections of the neck.

    Preferably said projection or projections is a circular projection.
     25
    Preferably said placket is attached to the hood by means of a hinge and a pre-cut line, also having a groove to facilitate its operation.

    Preferably said placket is attached to the hood by means of a hinge and a pre-cut line, said placket also having a ring with an inner hole to facilitate its operation.

    Preferably said membrane is an independent piece of the hood that is disposed under said upper area of the hood.
     35
    Preferably said membrane has a circular main body designed to completely cover the mouth of the bottle.

    Preferably the membrane is a bi-injected piece in two materials, the main body being manufactured in one material and presenting a circular crown-shaped area 5 in another material softer than that of the main body, said area being in the form of a circular crown intended to come into close contact with the uppermost wall of the bottle neck.

    Preferably, the membrane comprises a trumpet-shaped projection in flexible material 10 that bends outwardly when the cap is introduced into the bottle, thereby sealing the liquid outlet.

    For your better understanding, representative drawings are attached, by way of explanatory example, but not limitation, of two specific embodiments of the cap object of the present invention.

    Figure 1 shows a perspective view of the closure cap of a bottle.

    Figure 2 shows a perspective view of the cap with the flap. twenty

    Figure 3 shows a perspective view of the cap detached from the bottle.

    Figure 4 shows a sectional view of a first embodiment of the cap.
     25
    Figures 5 and 6 show sectional views of a second embodiment of the cap.

    Figure 7 shows a sectional view of the third embodiment of the cap.

    Figure 8 shows a perspective view of a third embodiment of the cap. 30

    Figures 9 and 10 show the process of opening a third embodiment of the cap.

    In Figure 1, a plug -1- according to the invention is shown attached to a bottle -2-. Figure 1 shows the cap of said cap. Said cap has a placket -3- 35
    in the central area of the cap with a precut -10- on the perimeter of the aforementioned placket -3-. Said placket -3- can be lifted by pulling the slot -11- using the hinge -12-.

    In figure 2, all the elements of the cap shown in figure 1 can be seen. When lifting the placket -3- pulling the groove -11-, the precut -10- and the placket -3- of the 5 are broken. central area of the cap rotates on the hinge -12- and leaves the membrane -4- visible.

    Figure 3 shows the process of opening the bottle cap by pulling the cap -3- vertically in the opposite direction to the bottle as indicated by the arrow in Figure 3 and it is possible to separate the cap -1- from the neck -6- of the bottle -2-. 10

    Figure 4 shows a sectional view from the central point of a first embodiment of the plug in which the -4-bi-injected membrane has two different materials. A soft material -5- that is arranged in an area in the form of a ring or circular crown in the contact part with the uppermost wall of the neck of the bottle -6- and its function is to allow the sealing of the cap. The main body of the membrane -4- is made of another material more suited to its structural function.

    The cap -1- has a circular protrusion -7- that fits the protrusion of the bottle neck -6- by dimensional interference in order to allow the fixation of the cap -1- to the neck of the bottle -6- preventing the vertical movement of the cap -1- in the opposite direction to the bottle. The figure shows the existing dimensional interference.

    A sectional view of a second embodiment of the present invention is shown in Figures 5 and 6. The membrane -4’- comprises a trumpet shaped projection. The protrusion is constituted by two parts, a vertical part -8- and an inclined part -9- towards the outside of the plug. At the confluence of both sides a weakening has been provided that favors the bending of the wall by the line of weakening. The inclined part -9- is deformed by inserting the cap -1- into the neck of the bottle -6- as shown by the arrows in Figure 5, which makes the projection wall shaped like a trumpet it bends by the weakening and is as schematically represented in figure 6. The folded part is thus in contact with the inner wall of the bottle neck and exerts pressure against it, which seals the passage of liquid through said inner wall, thus ensuring tightness.
     35
    Figure 7 shows a sectional view of the third embodiment corresponds to Figure 4, except that the placket corresponds to a ring -13-. The membrane -4- has two different materials obtained by bi-injection: the soft material -5- and the membrane -4- made with harder material.
    On the one hand, soft material -5- is arranged in a circular ring or crown-shaped area 5 in the contact part with the uppermost wall of the neck of the bottle -6- and its function is to allow the seal of the plug. On the other hand, the main body of the membrane -4- is made of another material more suitable to its structural function, presenting a circular flange -15- to be suitable at a pressure of the membrane -4- by the user through of the hole -14- to facilitate the opening of the stopper -1- by pulling the ring -13-.

    Several perspective views of a third embodiment of the present invention are shown in Figures 8-10.
     fifteen
    The plug -1- is attached to the ring-shaped placket -13- by precuts -10-. Said ring -13- has a hole -14- in its central part. The ring -13- is articulated by the hinge -12- by lifting the ring -13- through its hole -14-. (see figure 9). In figure 10, the process of opening the cap -1- of the bottle by pulling the ring -14- is observed.
     twenty
    This embodiment has more opening facilities than the embodiments described above since the membrane -4- being flexible allows the ring -13- to be pulled through its hole -14- more easily.

    While the invention has been described with respect to examples of preferred embodiments, these should not be construed as limiting the invention, which will be defined by the broader interpretation of the following claims.
