Description

The invention relates to containers, in particular, to the design of neck closures for bottles, made with the function of not only reliable closure, but also to demonstrate the integrity of the closure.

Known throat shutter containing a housing installed in the neck of the tank, made with a drain hole and in the inner cavity of which a valve is freely placed with the possibility of separation of the cavity of the tank and the cavity of the drain hole of the housing in the vertical position of the tank and the message of these cavities when emptying the tank, said valve is made with a cone the seating surface and with the blades to ensure fluid swirl when emptying the tank, made on the valve from the side of the tank cavity and Whether the body cavity, and on the wall of the drain body, the part of the latter, opposite the placement of the valve blade made for additional vortical swirling flow discharged from the liquid container (RU №2231487).

Known lid-stopper with a tear-off element, characterized in that the lid is made in the form of a cup equipped with a cap (made cylindrical with a flat lid), and the tear-off element with a gripping lobe has an elastic inner flange in the lower part, while the lid with a tear-off element and a stopper made of polymeric material, the cap is made of metal, for example steel, the outer perimeter of the cork has an annular flap elastic protrusion with the possibility of its interaction with the flanging of the cap (RU No. 2006102434, B65D 41/00, publ. 08.20.2007) . Adopted as a prototype for the claimed object.

The disadvantage of this neck shutter is its weak operational reliability.

The present invention is aimed at solving the technical problem of creating a cork of a reliable design for sealing and holding it on the neck of a bottle with elements of demonstration of factory closure.

The technical result achieved in this case is to increase the operational reliability of the use of the shutter while simplifying the design.

The specified technical result for the device is achieved by the fact that in the neck of the bottle closure containing a stopper of a polymeric material having an outer cylindrical wall to cover the neck of the bottle, a metal cap covering the stopper from the side of the end of the stopper, and a tear-off element in the form of a tape with a gripping tab on a cylindrical wall, a metal lid in the form of a cup is made with internal flanging, and on the outer surface of the cork an annular hook is made, which, in the process of landing of the lid on the cork it starts to abut against the wall of the lid, while the lid abuts against the end part of the cork to hold the lid on the cork, and the tear-off element in the form of a tape is made integral with the cylindrical wall of the cork and is an extension of this wall along its height, the cylindrical wall is at a level below the location of the tape the tear-off element is made with a hook to cover the rim of the bottle, and on the inside the casing is made mushroom-shaped to place it in the neck of the bottle.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

According to the present invention, a neck closure design for a bottle with a neck, designed to reliably seal and demonstrate the integrity of the closure, is considered.

The neck closure for a bottle contains a stopper made of a polymer material having an outer cylindrical wall to cover the neck of the bottle, a metal cap covering the stopper on the side of the end face of the stopper, and a tear-off element in the form of a tape with a gripping tab on a cylindrical wall. The metal lid in the form of a cup is made with internal flanging, and an annular hook is made on the outer surface of the cork, which, when the lid is planted on the cork, is crushed to abut against the wall of the lid, while the lid abuts against the end part of the cork to hold the lid on the cork. The tear-off element in the form of a tape is made integral with the cylindrical wall of the cork and is a continuation of this wall along its height, the cylindrical wall at a level below the location of the tape of the tear-off element is hooked to cover the rim of the bottle, and on the inside the casing is made mushroom-shaped for placement in the neck of the bottle.

The following is a specific example of shutter performance.

The shutter consists of two parts: a stopper 1 (Fig. 1, 3-6) made of medium-density polyethylene grades permitted for contact with food products, and a lid 2 (Fig. 2) made of white metal sheet with a thickness of 0.15 mm) .

The cork is a one-piece polymer product, which can conditionally be divided by perforation 3 into two parts:

the upper one is a polymer plug in the form of a hollow body having, on the outside, a diameter of a hook 4 for fitting a metal cover 2 (Fig. 1), which is made in the form of a polymer cilia. On the inside, the casing is made in the form of a hollow mushroom-shaped cork with a double wall 5, which allows tightly corking the neck of the bottle (while the elasticity of the material used and the design of the double wall allow springing of the fitting of the outer wall of the cork to the inner wall of the neck of the bottle). And the outer metal cover does not allow deformation of the hollow mushroom plug due to bearing in the thrust pad 6, which is adjacent to the metal cover;

the lower one is a tear-off tape 7 having vertical ribs-hooks 8 from the inside of the horizontal offset diameter relative to the neck of the bottle. To protect against vertical displacement along the diameter of the tear-off tape, an annular hook 9 is located in its lower part, which, when corked, is tucked and hooked onto the ring rim of the bottle. The design (geometry) is designed in such a way as to ensure automatic bottle corking using standard orienting and capping equipment of the plants. Tear tape for ease of tearing has an extended shape tail 10.

The cover 2 is a stamped metal part of a glass-like shape made of white food sheet with a thickness of 0.15 mm, a diameter of 6.3 mm and a height of 5.8 mm, having a special hook on the inside of the gate in the form of a gate 11 with a height of 1.15 mm.

Functional purpose of the cover:

- provides a hard fit of the polymer part on the neck of the bottle;

- protects the plastic part (cork) from mechanical damage (penetration to the contents of the bottle);

- is a decorative element (drawing a logo, painting, etc.).

The stopper 1 is inserted into the neck of the bottle so that its inner hollow mushroom-shaped part abuts against the inner wall of the neck of the bottle. When a metal cap is put on top, it crushes the cilia of the hook 4 and abuts against the thrust pad 6. When the lid is removed, the cilia are damaged, and when the cork is removed, the tape 7 breaks and the hook 9 deforms, which indicates a previous action to open the bottle. Since capping is automatic, the integrity of the shutter indicates factory corking and the authenticity of the product.

The present invention is industrially applicable and can be manufactured using the technologies used for the manufacture of polymer valves.
