RU48521U1 - Cork made of thermoplastic material for bottle closure - Google Patents

Abstract

The utility model relates to closures and may find application in capping bottles with liquid. The essence of the utility model: a plug made of thermoplastic material contains a housing in the form of concentrically located outer and inner tubular elements with a common bottom and an annular protrusion on the inner surface of the outer tubular element. The outer tubular element is made in the form of a radially rounded part adjacent to the bottom and a removable skirt with a protruding tip that adjoins the annular protrusion of the radially rounded part of the outer tubular element. Four sealing annular conical flanges are arranged stepwise along the edge of the bottom and on the inner surface of the outer tubular element, the height of the inner tubular element of the tube being approximately half the height of the outer tubular element, and a groove is made on the left side of the protruding tip on the inner surface of the removed skirt, which is a line openings of a stopper and the ring ledge of a radially rounded part of an external tubular element bordering an arch of 270 °. During transportation, storage and operation of the bottles there is no leakage of water due to reliable sealing with a stopper.

Description

The utility model relates to closures and can be used to seal bottles with liquid.

Known products of this type described in patents of the Russian Federation: No. 2150417 "Safety cover", B65D 49/02, published on 10.06.2000;

No. 2133701 “Re-closing, opening-detecting plastic cover”, B 65 D 41/38, B 65 D 47/24, published July 27, 1999;

No. 2215675 “Compound element consisting of a plastic container lid and a plastic stopper”, B 65 D 47/06, published 10.11.2003.

A disadvantage of the known technical solutions is the technical complexity in their manufacture and unreliable sealing of the necks.

Closest to the technical nature of the claimed utility model is “Cork from a thermoplastic material for corking bottles” according to the patent of the Russian Federation No. 2108276, B 65 D 41/02, published on 10.04.1998. Known cork is technologically difficult to manufacture.

The objective of the claimed utility model is to create a cork made of thermoplastic material for capping bottles with drinking mineral water, convenient in operation with a reliable seal neck, preventing the flow of water, preserving sealing for a long time with a simple manufacturing technology.

The technical result of the utility model is reliable sealing of bottles and providing ease of uncorking.

The technical result is achieved by the fact that the cork of a thermoplastic material for bottle capping contains a housing in the form of concentrically located outer and inner tubular

elements with a common bottom and an annular protrusion on the inner surface of the outer tubular element. The outer tubular element is made in the form of a radially rounded part adjacent to the bottom and a removable skirt with a protruding tip that adjoins the annular protrusion of the radially rounded part of the outer tubular element. Four sealing annular conical flanges are stepwise arranged along the edge of the bottom and on the inner surface of the outer tubular element. The height of the inner tubular element is about half the height of the outer tubular element. An annular groove is made on the left side of the base of the protruding tip on the inner surface of the removed skirt, which is the tube opening line and the ring protrusion of the radially rounded part of the outer tubular element bordering the 270 ° arc.

Figure 1 presents a General view of the cork of a thermoplastic material for capping bottles with the image of the cross section "A" of the cork on an enlarged scale.

The plug of thermoplastic material consists of a body in the form of an outer tubular element, consisting of a radially rounded part 1 with an annular protrusion of the radially rounded part of the outer tubular element 2, on the inner surface of which there are sealing annular conical flanges 3, and skirts 4 with a protruding tip 5, the inner the tubular element 6, the bottom 7 and the annular groove 8, which is the tube opening line, and on the skirt 3 of the inner surface of the outer tubular element at the same size sealing from each other made sealing tabs 9.

The outer tubular element is made in the form of a radially rounded part 1 adjacent to the bottom 7, the outer surface of which is made smooth. On the inner surface of the edge of the bottom 7 and the radially rounded part of the outer tubular element, four ring-shaped steps are arranged at a distance of about 2 mm from each other

sealing conical flange 3 with a spherical top, the protruding part of which is approximately 1 mm

The presence of sealing conical flanges 3 in the radial part of the outer tubular element 1 of the cork body ensures reliable tightness of the water bottles during their operation, transportation and storage. In addition, on the skirt 4 of the inner surface of the outer tubular element at the same distance from each other, sealing projections 9 are made, providing a tight grip around the neck of the bottle.

The removable skirt 4 with the protruding tip 5 is adjacent to the radially rounded part of the outer tubular element 1, which is separated by an annular groove 8, which surrounds the 270 ° arc with an annular protrusion of the radially rounded part of the outer tubular element 2. The groove 8 serves as a separation line for the removable lower part and facilitates the opening of the bottle. The protruding tip 5 has a corrugated inner surface for ease of gripping with fingers.

The outer and inner surfaces of the inner tubular element 6 are made smooth. The wall of the inner tubular element and the wall of the outer tubular element has a thickness of up to 2 mm.

The cork is used as follows: the cork is pressed under pressure onto the neck of 19 liter bottles filled with natural drinking mineral water extracted from the well. During transportation and storage of bottles, water does not leak due to reliable sealing with a stopper. The inventive design of the cork allows you to successfully use it both in the operation of bottles using coolers (dispensers) of various designs, and using a pump, while uncorking the bottles by removing the skirt for the protruding tip of the outer tubular element.
