Bottle cap with a lock

Abstract

A bottle cap with a lock has a hollow barrel, a plug received into the hollow barrel, a ring provided under the plug, and a fastener. When a bottle neck is mounted with the bottle cap with the lock and the plug rotates relative to the hollow barrel via a key, the fastener slides upwardly adjacent to the plug thereby compressing against the ring to expand to lock the bottle. When rotating the key backwardly, the fastener slides downwardly opposed to the plug thereby the ring being shrunk to get back to an original status so that the ring and the fastener can be taken off from the plug easily for cleaning.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a bottle cap with a lock, and more particularly to a bottle cap which can be locked on a re-seal bottle to prevent drinking by mistake or by purpose, or being poisoned by others, and which can be cleaned conveniently. [0003] 2. Description of Related Art [0004] A conventional bottle cap such as a cork is used to seal a bottle neck for wine or beverage. When the drink is not completely consumed, it is not convenient for a drinker to re-seal the bottle neck with the bottle cap. [0005] When people exercise together and their refreshment bottles are grouped together, it is difficult for those people to find their individual bottles and this may pose a health risk. [0006] When the re-seal wine is stored in a hotel, it is easy to be drunk by mistake or by purpose, i.e., the opened bottle is accessible by children or, a person may secretly drink another person's wine. [0007] When the re-sea...

AI Technical Summary

Benefits of technology

[0012] The main objective of the present invention is to provide a bottle cap with a lock which can be locked on a re-seal bottle to prevent drinking by mistake or by purpose, or being poisoned by others, and which can be cleaned conveniently.

[0017] whereby when the ring is inserted into a bottle neck and the plug rotates relative to the hollow barrel via the rotation of the key in a first direction, the fastener slides upwardly adjacent to the plug thereby compressing against the ring to expand so that an outer wall of the ring securely attaches to an inner wall of the bottle neck to lock the bottle; when the key is rotated in a second direction opposed to the first direction, the plug rotates and the fastener slides downwardly opposed to the plug thereby the ring can resume its original pre-expanded status so that the present invention can be separated from the bottle neck; when continuing rotating the key in the second direction, the shaft separates from the hole and the opening, the ring and the fastener can be taken off from the plug for cleaning. Hence, the bottle cap with the lock is easy to use and has a simple configuration.

Problems solved by technology

When the drink is not completely consumed, it is not convenient for a drinker to re-seal the bottle neck with the bottle cap.

When people exercise together and their refreshment bottles are grouped together, it is difficult for those people to find their individual bottles and this may pose a health risk.

When the re-seal beverage is put in the public, it is easy to be drunk by mistake or by purpose or be poisoned.

When the re-seal chemical is stored in the chemical factory or in the laboratory, it is easy to be used or taken by mistake.

When the re-seal medicine is stored in the hospital, it is easy to be taken or mixed by mistake.

A further situation concerning caps of bottle-like containers is that a child may take medicine in error when the bottle cap for the medicine bottle is not locked.
