Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap technology, and more specifically, to an anti-pull-out steel ring and an anti-pull-out bottle cap. Background Technology
[0002] In existing technologies, unscrupulous vendors can heat the bottle cap to a high-temperature environment and then use equipment to pull it evenly so that the bottle cap detaches from the bottle opening. The teeth that hold the bottle cap in place at the bottle opening soften under high temperature, allowing it to detach from the bottle opening, thus causing the connection between the bottle cap and the bottle opening to fail. This allows them to replace the wine in the bottle to counterfeit it before reattaching the bottle cap. Therefore, a technical solution is needed to solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and prevent the bottle cap from being softened and pulled out, and to provide an anti-pull-out steel ring and an anti-pull-out bottle cap.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model discloses an anti-pulling steel ring, including a steel ring, the side wall of the steel ring including a first part, the steel ring having a plurality of first windows distributed in a ring in the first part, the steel ring having a plurality of clamping plates, the clamping plates being located at the lower edge of the first windows, the clamping plates being inclined, and the upper end of the clamping plates being inclined toward the center of the steel ring.
[0006] Furthermore, the card plate includes an inclined plate and a vertical plate. The vertical plate is connected to the lower edge of the first window and extends vertically upward. The inclined plate is located at the upper end of the vertical plate, and the upper end of the inclined plate is inclined toward the center of the steel ring.
[0007] Furthermore, the card plate and the steel ring are integrally formed.
[0008] Furthermore, the sidewall of the steel ring includes a second part, which is integrally formed with the first part. The second part is located below the first part and has multiple positioning holes located on the lower end face of the steel ring.
[0009] Furthermore, the steel ring includes a ring plate located at the upper end of the steel ring, the ring plate being integrally formed with the steel ring, and the ring plate being located on the inner side of the steel ring.
[0010] Furthermore, the ring plate is provided with multiple locking teeth, which are distributed in a ring shape.
[0011] A bottle cap designed to prevent pull-out, characterized in that the aforementioned anti-pull-out steel ring and shell are provided, wherein the shell is made of plastic, the steel ring is fixed to the shell by injection molding, the shell covers a portion of the steel ring, and the shell is provided with a plurality of second windows, each second window corresponding to a first window.
[0012] Furthermore, a portion of the card plate extends out of the housing, the card plate extends toward the inner wall of the housing, and the card plate extends inwardly out of the inner wall of the housing.
[0013] The beneficial effects of this utility model are:
[0014] The bottle cap of this invention strengthens the structure of the shell by injecting a steel ring into the shell during the injection molding process, reducing the degree of shell deformation due to heating. The inwardly bent and inclined clamping plate can deform and lock into the bottle mouth for limiting the position. The metal clamping plate can also be released from the limiting position, making it more secure and less prone to deformation. Attached Figure Description

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1-3As shown, this embodiment discloses an anti-pull-out steel ring and an anti-pull-out bottle cap using the same anti-pull-out steel ring. The steel ring 1 and the shell 2 are included. The steel ring 1 is made of metal, such as stainless steel, and the shell 2 is made of plastic. The steel ring 1 is injection molded together with the shell 2 during the injection molding process, so that the steel ring 1 can be enclosed and fixedly connected by the shell 2. The ring shape of the steel ring 1 can strengthen the strength of the plastic material of the shell 2. The degree of thermal expansion and contraction of metal is less than that of plastic. The steel ring 1 can prevent the shell 2 from deforming due to heat and prevent the bottle cap from easily expanding after being heated.
[0021] The steel ring 1 is generally annular. The sidewall of the steel ring 1 includes a first part 11 and a second part 12. The steel ring 1 has multiple first windows 111, which are distributed in a ring on the first part 11. The first windows 111 are formed by cutting. The steel ring 1 has multiple retaining plates 112, which are located at the lower edge of the first windows 111. The retaining plates 112 are integrally formed with the steel ring 1. The retaining plates 112 and the first windows 111 are formed by cutting. The retaining plates 112 are inclined, with their upper ends inclined toward the center of the steel ring 1. The retaining plates 112 are formed by bending after cutting. The process creates an inwardly inclined structure. When the bottle cap is installed on the bottle neck, an outwardly protruding retaining ring is provided at the bottle neck. The bottle neck is installed into the housing 2 from below. The retaining plate 112 has elastic deformation capability. By pressing, the retaining ring can pass over the retaining plate 112, and then the upper end of the retaining plate 112 abuts against the lower side of the retaining ring. The housing 2 and the bottle neck bracket are installed in a limiting position, so that the retaining plate 112 plays a limiting and supporting role for the bottle neck. When the bottle cap is pulled outward, it will be locked and held by the retaining plate 112. The retaining plate 112 is extremely difficult to deform, so the bottle cap cannot be pulled out from the bottle neck, which achieves the effect of anti-counterfeiting and fixing.
[0022] More preferably, the clamping plate 112 includes an inclined plate 1121 and a vertical plate 1122. The vertical plate 1122 is connected to the lower edge of the first window 111 and extends vertically upward. The inclined plate 1121 is located at the upper end of the vertical plate 1122 and the upper end of the inclined plate 1121 is inclined towards the center of the steel ring 1. The housing 2 covers part of the steel ring 1, and part of the clamping plate 112 extends out of the housing 2. That is, the vertical plate 1122 is covered by the housing 2, while the inclined plate 1121 extends out of the housing 2. The housing 2 covering the vertical plate 1122 can strengthen the connection between the clamping plate 112 and the steel ring 1, prevent the vertical plate 1122 from deforming, and make the deformed part of the clamping plate 112 only on the inclined plate 1121. The clamping plate 112 extends towards the inner wall of the housing 2 and extends inward to the inner wall of the housing 2, so that the clamping plate 112 can engage with the bottle mouth located inside the housing 2.
[0023] The housing 2 is provided with multiple second windows 21, each second window 21 corresponding to a first window 111. The second part 12 is integrally formed with the first part 11 and is located below the first part 11. The second part 12 is provided with multiple positioning ports 121, which are located on the lower end face of the connecting steel ring 1. The positioning ports 121 are used to position the housing 2 with the mold during injection molding to ensure that the first window 111 and the second window 21 are positioned so that the position of the card plate 112 can be positioned with the position of the second window 21.
[0024] The steel ring 1 includes a ring plate 13, which is located at the upper end of the steel ring 1 and is integrally formed with the steel ring 1. The ring plate 13 is located on the inner side of the steel ring 1. The ring plate 13 can support the horizontal deformation of the steel ring 1 and limit the vertical direction between the steel ring 1 and the shell 2, thereby strengthening the structural strength of the steel ring 1 and making the shell 2 less prone to deformation. The ring plate 13 is provided with multiple locking teeth 131, which are distributed in a ring shape. The multiple locking teeth 131 can make the connection between the injection-molded shell 2 and the steel ring 1 more secure, and at the same time limit the rotation direction of the steel ring 1 and the shell 2, preventing the steel ring 1 from shifting after the shell 2 is injection-molded.
[0025] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
