Bottle lid

Abstract

A bottle lid provides a fluid tight seal that holds liquid contents in a bottle within the bottle, while preventing unwanted entry of another liquid or a gas, such as air, into the bottle, and in te case of a carbonated liquid in the bottle, maintains the carbonation while preventing the build up of internal overpressure in the bottle. The bottle lid includes a cap, and a lever actuated operating member, placed in the mouth of the bottle, with having a sealing element on the operating member. Actuation of the lever causes an elastic deformation of the sealing element, which expands radially outwardly against the inner wall of the bottle to provide the fluid-tight seal.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a bottle lid which features easy operation of a lever-actuated sealing member to seal the bottle in order to provide a superior sealing force against internal pressure in the bottle and which also features an anchoring member for securely holding the bottle lid to the mouth of the bottle to prevent inadvertent detachment of the lid from the bottle due to a build up of internal pressure in the bottle and / or external mechanical causes. [0003] 2. Description of the Related Art [0004] A conventional bottle lid of generally related functionality is restricted by Korean Utility Patent Registration No. 0346808, which is also owned by the present applicant. [0005] With the aforementioned conventional bottle lid, it is possible to maintain sealing force for a bottle in which the bottle neck is long and formed in the shape of that is the number “1”, however, when it is used for a bottle of whi...

AI Technical Summary

Benefits of technology

[0010] Accordingly, it is an object of the present invention to overcome the foregoing problems and disadvantages. This is accomplished in the present invention by providing a bottle lid and cap having an anchoring member in the cap that covers and fits over the outside of the bottle mouth, with the anchoring member being formed in order to securingly cooperate with an element on or near the mouth of the bottle itself, such as spiral threads, an attachment ring, or a lower lip on a bottle mouth, in a state wherein the lid and cap tightly adheres to the outside of the bottle mouth. The bottle lid and cap further includes an operating lever, which is actuated after first securing the anchoring device with the spiral threads of the bottle mouth. Actuation of the lever causes the sealing device to expand causing a tight fluid seal. The bottle lid is prevented from inadvertently detaching due to the presence of the anchoring member.

Problems solved by technology

With the aforementioned conventional bottle lid, it is possible to maintain sealing force for a bottle in which the bottle neck is long and formed in the shape of that is the number “1”, however, when it is used for a bottle of which the bottle neck is short or for any bottle that is filled with a carbonated beverage, the sealing device can easily get pushed upward toward the upper part of the neck and even become completely detached from the bottle due to internal pressure in the bottle, which is a disadvantage.

A bottle lid of this conventional configuration has a disadvantage in that it may still easily detach from and come off the bottle when internal pressure in the bottle increases or because of the geometry and shape of certain bottles, particularly when the neck of the bottle has an inclined side.

This occurs especially in cases where the bottle mouth is not formed in an elongated shape, resembling the outline of a numerical figure “1”, as in wine bottles, and sealing of the bottle is unstable, thereby causing, the cap to detach by itself after passage of a certain amount of time or eventually causing failure of proper sealing of the bottle, which is disadvantageous in that liquid may leak from the bottle if it is inadvertently tipped, the contents of the bottle, if carbonated, will lose carbonation and go “flat”, and / or air may seep into the bottle causing the contents to spoil.

Loosening, and possible detachment of the cap is a particular problem in cases in which internal pressure in the bottle builds up, as in the case of carbonated beverages, causing the sealing device which adheres to the inside of the bottle mouth to be pushed up to the upper part of the bottle mouth, causing the bottle cap to easily come off.
