RU2307775C1 - Bottle sealing prorective stopper - Google Patents

Abstract

FIELD: packing.

SUBSTANCE: proposed protective stopper contains decorative case with cap and shutoff bushing accommodating pourout tube. The latter is made for axial displacement and extending from shutoff bushing, when stopper is being opened, under action of spring placed inside shutoff bushing. Support guide for pourout tube is arranged inside shutoff bushing, in its lower part. Said guide is siphon to deliver air into bottle.

EFFECT: provision of protection of bottle with expensive liquid from refilling, with indication of first opening of bottle.

Description

The proposed device relates to closures for bottles with a particularly valuable liquid that protects against refilling and signals the first opening of the bottle.

The following technical solutions can be taken as analogues: WO 96/23904, 08/08/96; RU 2150417, 10.06.2000; GB 2099414, 12/08/1989; GB 2218590, 12.13.1989.

Known analogues include a drainage device, a fixing cap, a valve, a gasket, a cover and a locking sleeve. The cap and the locking sleeve are interconnected by jumpers formed by perforation. The drain device has ribs for distributing the flow over the free section. The locking sleeve on the inside has a flange for gripping the flange of the drain device. The valve serves to prevent re-filling. The plug is connected to the drain by means of a thread and sealed with a conical sealing ring.

Known analogues have a number of disadvantages, such as: jamming of the valve due to the short base length in the guide cavity; a large effort to detach the cap from the drain sleeve; The shut-off valve design does not guarantee refilling the bottle.

Closest to the proposed invention is a protective stopper (cap) for capping bottles, containing a decorative casing for installation on the neck of the bottle, a decorative cover with a tear-off element mounted for rotation relative to the fixing casing and with the possibility of interaction with rotation with a locking sleeve having a drain pipe made with the possibility of removing the tear-off element, and mounted on the drain sleeve with the possibility of axial movement of the locking sleeve during its rotation. A shut-off valve in the form of a ball is placed inside the shut-off sleeve to close the hole of the drain sleeve. The drain sleeve is made with a sealing skirt, which is hermetically inserted into the neck of the bottle (utility model of the Russian Federation No. 27061 U1, IPC ⁷ B65D 41/00, publication 01/10/2003).

Known cork has a complex structure and is not quite convenient for use. Another disadvantage of the known cork is not safety during its operation, because a tear-off element connected to the lid by means of a jumper, when squeezed out by the nozzle of the locking sleeve, can fly out with a sufficiently high force and cause injury to others.

An object of the invention is to develop a simple and reliable design of a protective stopper that protects against refilling the bottle.

The technical result of the invention is to increase the usability of the cork, to reduce the cost of its manufacture and to increase the safety of operation.

The technical result is achieved by the fact that the protective stopper for corking bottles contains a decorative casing with a lid, a locking sleeve, in which a drain pipe is arranged, which is capable of axial movement and extension from the locking sleeve when opening the stopper under the action of a spring placed inside the locking sleeve, which increases ease of use cork.

Inside the locking sleeve, a support guide for the drain pipe can be placed in the form of a tube fixed to the bottom of the locking sleeve and is a siphon for supplying air to the bottle. The implementation of the guide in the form of a siphon ensures a quiet pouring of liquid from the bottle.

An inner flange may be formed in the upper part of the locking sleeve, into which the lower part of the drain pipe abuts in the extended position, which, to prevent liquid from flowing outside the drain pipe, preferably has a conical shape.

The decorative casing and cover are preferably made of aluminum or an alloy based on aluminum.

The essence of the proposal is illustrated by drawings.

Figure 1 shows a longitudinal section of the plug in the open position.

Figure 2 is a longitudinal section of the cork in the closed position.

The protective stopper for corking bottles consists of a decorative casing (not shown) with a cap 1, a locking sleeve 2, a drain pipe 3, a spring 4 placed on the guide 5 of the drain pipe. The guide 5 is in the form of a tube communicating the space under the locking sleeve 2 with the space above the locking sleeve 2 and serving as a siphon. The tube is mounted on the locking sleeve 2 and is located inside the drain pipe 3 and the spring 4. In the closed position of the tube, the spring 4 is in a compressed position. An inner flange 6 is made in the upper part of the locking sleeve, into which the lower conical part 7 of the drain pipe 3 abuts in the extended position.

Use the protective plug as follows.

When removing the aluminum cap 1 from the bottle, the spring 4 is unclenched, which pushes the drain pipe 3 from the bottle neck to the stop of the conical part 7 of the drain pipe 3 in the flange 6 of the locking sleeve 2. The presence of an air supply siphon in the bottle additionally ensures a smooth pouring of liquid from the bottle.

This design of the protective plug provides simplicity and cost-effectiveness of manufacture, reliability, safety and ease of use.
