Anti-pumping rubber bottle stopper

Abstract

The invention discloses an anti-pumping rubber bottle stopper which is of a T-shaped structure, and comprises a crown part and a stopper neck. The stopper neck is a hollow cylindrical body, and the outer diameter of the stopper neck is equal to or slightly less than the inner diameter of a bottle opening. One or more ledges are distributed on the outer surface of the stopper neck, and are parallel to the stopper neck. The circumcircle diameter of the leads is slightly larger than the inner diameter of the bottle opening. According to the invention, the internal pressure generated when the bottle stopper is placed into the bottle opening is released, thereby preventing the bottle stopper from being ejected out of the bottle opening by the internal pressure, avoiding the problem that the product quality is influenced by bottle stopper drop and the like, and finally increasing the availability of the product.

Description

(1) Technical field: [0001] The invention relates to an anti-jump rubber bottle stopper for medicine packaging. (two) background technology: [0002] Rubber stoppers are widely used in the sealing of glass bottles for pharmaceutical packaging. It is a T-shaped structure consisting of a crown and a stopper neck. The stopper neck is hollow inside and cylindrical in appearance. The outer diameter of the stopper neck is equal to or slightly larger than the inner diameter of the bottle mouth. , when the cork is inserted into the mouth of the bottle, the air in the bottle is compressed to form an internal pressure, the cork is easily pushed out by the internal pressure, causing it to fall off, and the cork will cause new pollution, and repeated cleaning and use or direct scrapping will increase cost. For this reason, Chinese patent 02258042.5 (CN2589362) discloses a rubber bottle stopper that prevents jumping. The friction force makes the cork form an anchor hook effect in the b...

[0002] Rubber stoppers are widely used in the sealing of glass bottles for pharmaceutical packaging. It is a T-shaped structure consisting of a crown and a stopper neck. The stopper neck is hollow inside and cylindrical in appearance. The outer diameter of the stopper neck is equal to or slightly larger than the inner diameter of the bottle mouth. , when the cork is inserted into the mouth of the bottle, the air in the bottle is compressed to form an internal pressure, the cork is easily pushed out by the internal pressure, causing it to fall off, and the cork will cause new pollution, and repeated cleaning and use or direct scrapping will increase cost

For this reason, Chinese patent 02258042.5 (CN2589362) discloses a rubber bottle stopper that prevents jumping. The friction force makes the cork form an anchor hook effect in the bottle to solve the phenomenon of cork jumping. However, it does not perform well in practical applications, and the above-mentioned problem of plug jumping cannot be fundamentally solved.
