Description

The invention relates to packaging, in particular to means for capping bottles with an indication of opening, mainly for bottles with elite alcoholic beverages.

Beverage manufacturers are interested in ensuring that their products delivered to the market are protected from unauthorized opening until they are opened by the final consumer of the product. For this purpose, the closures are provided with means that will indicate whether the opening was made prior to sale or not.

Although various tamper evident devices have been widely recognized, it is very difficult to satisfy all conflicting manufacturer requirements. On the one hand, it is necessary that the closures can be manufactured and placed on bottles at a sufficiently high speed without inadvertently destroying or deforming the indicating means itself. On the other hand, after the closure device has been fully installed, the indicating means must be firmly fixed under the retaining element of the closure structure, and the requirements of bottle manufacturers for such reliable fastening are becoming more severe.

In this direction it is known, for example, the technical solution according to the patent of the Russian Federation for the invention No. 2161585, B65D 41/38.

Description

The closure device includes a metal casing 1, which consists of two contacting parts, from the upper part - a metal cap 2 and the lower part - a metal sleeve 3, a plastic sleeve 4 with an internal thread and with a tamper indicating element 5, an inner polymer cover 6, mounted between the metal cap 2 and a plastic sleeve 4, a divider 7 having an internal cavity and a pouring hole made with an external thread interacting with the thread of the plastic sleeve 4.

The divider 7 also contains an inner conical ring 8, interacting with the sealing ring element 9 of the plastic sleeve 4.

Inside the divider 7, a locking rod 10 is installed, which is necessary for the implementation of the anti-spill function. The locking rod 10 after opening the closure device does not allow re-filling the liquid into the container after emptying it.

The divider 7 also contains a sealing sleeve 11 mounted in the internal cavity of the divider 7 in a tight mechanical fit and containing flexible lamellas 12 and an annular seal 13.

The tamper indicating element 5 is made along the contour in the lower part of the plastic sleeve 4 in the form of an annular conical-shaped belt, with a large diameter facing the metal sleeve 3, which is the lower part of the casing.

The tamper indicating element 5 is rolled under the upper edge 14 of the metal sleeve 3, tightly fixed on the divider 7, and is made with the possibility of releasing from the upper edge 14 of the metal sleeve 3, signaling the first opening of the closure.

The inner polymer cover 6 can be connected to the metal cap 2 by means of a tight mechanical fit or adhesive, and with a plastic sleeve 4 by means of a mechanical one-piece connection. This mechanical one-piece connection can be achieved by tightly fixing the horizontal annular buffer elements 15 located on the outer radial surface of the plastic sleeve 4, in the reciprocal horizontal annular buffer elements 16 located on the inner radial surface of the inner polymer cover 6.

The metal sleeve 3 can be tightly fixed to the divider 7 by rolling the metal sleeve 3 into a horizontal annular groove 17.

The outer surface of the metal cap 2 can be knurled or corrugated, and the plastic sleeve 4 can be made of colored material. Assembly order.

A locking rod 10 and a sealing sleeve 11 are installed in the divider 7. Then, a plastic sleeve 4 is screwed on the divider 7. Next, a metal sleeve 3 is installed on the assembled structure, after which it is rolled into a horizontal annular groove 17.

A metal cap 2 is mounted on the inner polymer cover 6, after which the assembled structure is mounted on the plastic sleeve 4.

The interaction of the elements of the device.

When closed, the tightness of the device is provided by the locking rod 10, which is constantly pressed against the seat 18 of the sealing sleeve 11 by the pusher 19 located in the center of the plastic sleeve 4.

Reliable protection against fluid leakage in the assembled state of the closure device is also provided due to the presence on the divider 7 of the inner conical ring 8, which interacts with the sealing ring element 9 of the plastic sleeve 4.

When the capping device is uncorked, the metal cap 2, the inner polymer cover 6 and the plastic sleeve 4 translate upward, while the tamper indicating element 5, which has elastic and flexible properties, is released from under the upper sealed edge 14 of the metal sleeve 3, while becoming visually affordable, that is - an autopsy alarm occurs.

For a more intuitive tamper alarm, the tamper indication element 5 can be made of a material of contrasting color with the color of the casing 1.

With a fully uncorked capping device, the locking rod 10 depressurizes the system, allowing the pouring of liquid contents.

When the device is resealed, the tamper indicating element 5 prevents the metal cap 2, the inner polymer cover 6 and the plastic sleeve 7 from returning to its original position and serves to visually control the opening of the closure device, since it cannot be hidden under the upper sealed edge 14 of the metal sleeve 3.

This invention allows to develop a simpler and more reliable design of the capping device with an indication tool that would satisfy high consumer qualities, which provides high performance, reasonable cost, increased level of protection against unauthorized opening and anti-flood function, as well as increased comfort when using it.
