RU47855U1 - ALUMINUM-PLASTIC COVER, PROTECTING AGAINST THEFT, WITH THREADED INTERNAL PLUG - Google Patents

Abstract

The anti-theft aluminum-plastic combination cover with an internal screw plug includes a valve blocking the hole (1), an internal plug (2), an external aluminum tube (4) and a glass ball (3) located inside the valve (1), blocking hole. The features of the cover are that the valve blocking the hole has a convex shape, ribbed elements (5) are applied to the convex surface, and grooves (6) corresponding to the ribbed elements (5) are applied to the inside of the upper part of the inner plug (5) on the outside there are at least two ribbed elements (7). The model is characterized by simplicity of design, high performance and ease of operation.

Description

This design can be used in bottle caps, in particular, in aluminum-plastic combination caps with the function of preventing unauthorized opening and pouring into the bottle, containing an internal threaded cap forming one unit with the neck of the bottle.

Currently, most bottle caps consist of inner and outer caps. In this case, the inner cap is usually formed by internal fittings and a hole for the bottle. The outer part of the bottle cap is wrapped in an aluminum wrapper with a tube-like shape with a transverse, covering a seam in the form of a continuous line. When they try to open the lid, the seam is torn. The inner plastic cap in known bottle caps is formed by internal fittings and a bottle opening. As a rule, such covers are characterized by excessive design complexity. In addition, the technology of their production is also complicated, which limits the possibilities of production.

The objective underlying this utility model is to overcome the above drawbacks of the prior art, and to create a combined aluminum-plastic cap with a tamper-proof function, equipped with an internal screw plug, with a simple internal plug design that would form a single unit with a bottle opening and could be produced using a highly efficient and simple technological method.

The problem is solved by developing an aluminum-plastic combination cover, including: a valve (1) blocking the hole, an internal plug (2), an external aluminum tube (4) and a ball (3) located inside the valve (1) blocking the hole, different in that the valve blocking the hole has a convex shape, ribbed elements (5) are made on the convex surface, and grooves (6) corresponding to the ribbed elements (5) are made on the inside of the upper part of the inner plug (2), on the outside of the plug shki (2) formed by at least two fin member (7). In addition, in an alternative embodiment, the ball (3) can be made of glass, and on the outer side of the inner tube (2) four ribbed elements (7) can be made.

The use of the new design in comparison with the well-known developments has the following advantages: the valve (1) blocking the hole has a convex shape, there are ribbed elements on the convex surface (5); on the inner side of the upper part of the inner plug (2) there are slots (6) corresponding to the ribbed elements (5), therefore, the valve (1) blocking the hole and the inner plug (2) can freely communicate with each other, which reduces the number of technological operations by production of a cover. On the outside

at least two ribbed elements are made, which provides a connection with the bottle opening and, in turn, also reduces the number of operations in the production process, increasing productivity.

The described design of the cover is illustrated in the drawing.

The inner plug (2) serves as both the inner plug itself and the opening for the bottle. The internal plug (2) and the valve (1) blocking the hole are already arranged, which allows to reduce the number of technological operations in the production of the cover and to avoid the presence of impurities. Such a bottle cap by joining (for example, gluing) the inner plug (2) and the glass ball 3 prevents pouring into the bottle. When the bottle is uncorked, the upper part of the aluminum tube (4) is rotated, while its lower part can slightly rotate together with the upper part until it locks. With continued rotation of the upper part of the aluminum tube (4), the connection between the upper and lower part of the aluminum tube (4) breaks; the upper and lower parts of the aluminum tube (4) are separated from each other, the connection between them is no longer restored, which protects the bottle from reuse.

Claims (2)

1. An aluminum-plastic combination cap that protects against unauthorized opening and pouring into the bottle, including a valve (1) blocking the hole, characterized in that the valve blocking the hole is made with a convex surface on which ribbed elements (5) are made, and grooves (6) corresponding to the ribbed elements (5) are formed on the inner side of the upper part of the inner plug; at least two ribbed elements (7) are made on the outer side. 2. The aluminum-plastic combination cover according to claim 1, characterized in that four ribbed elements (7) are made on the outer side of the inner cover.
