Abstract

The present invention relates to a bottle cap structure, which mainly comprises a resilient pad integrally formed on a cavity of a cover body covering a cavity, and a stainless steel lining is disposed on the cover body of the cover body, thereby When the bottle mouth is covered, the stainless steel lining can be adjusted to a proper cover angle with the elastic pad to tightly cover the bottle mouth. Accordingly, when the contents of the bottle are flowed to the bottle mouth and the stainless steel piece When it comes into contact, the toxic substances such as plasticizers do not dissolve into the contents, and further, since the artificial mat integrates the elastic mat with the top of the cover body covering the cavity, it can be avoided. In the meantime, there is a situation in which the assembly gap is contaminated, so as to improve the health and safety of the contents of the bottle.

Description

Cap structure

The present invention relates to a bottle cap structure, in particular to a method for preventing an assembly gap between the cap body and the elastic pad, and to avoid toxic substances such as plasticizers from being dissolved, so as to improve the structure of the bottle cap for hygienic safety.

According to the existing bottle body provided with water, beverage, etc., a cap is placed at the mouth of the bottle, and in order to prevent leakage of liquid contents in the bottle, the existing cap is mostly inside the cap. A gasket is added to the upper end to improve the adhesion between the cap and the mouth of the bottle.

However, the design of the elastic gasket on the inner surface of the cap is formed by forming an assembly gap between the cap and the gasket, and the gasket is not easily taken out after being assembled in the cap. Therefore, the gap between the cap and the gasket is assembled. That will form a dead corner on the cleaning, causing water, dirt, oil stains, etc. to be hidden in the gap, causing problems such as bacterial growth and mildew, and affecting the cleanliness of water, beverages and the like in the bottle, and the other gasket It may also be dropped from the bottle mouth to affect the safety of the contents. Furthermore, when the content of the liquid contained in the bottle body is in contact with the inner surface of the cap and the gasket against which the bottle mouth abuts, the plasticizer contained in the plastic bottle cap and the gasket is dissolved into the contents, when people After eating the contents containing the plasticizer, the toxicity of the plasticizer will cause the human body's immunity, fertility and cancer.

The reason is that the creator has made the above-mentioned deficiency in view of the fact that the existing bottle caps still have the above-mentioned defects in the implementation and use of the manufacturing and design experience and knowledge of the related fields, and through various ingenuity, research and creation of this creation.

The present invention relates to a bottle cap structure, the main purpose of which is to provide a bottle cap which can prevent assembly gap between the cap body and the elastic pad, and can avoid toxic substances such as plasticizers, so as to improve the use of sanitary caps. structure.

In order to achieve the above-mentioned implementation objectives, the present author has developed the following cap structure, which mainly includes:

a cover body is formed with an opposite first open end and a first closed end, and a hollow cover cavity is formed therein, the cavity of the cover cavity is located at the first open end, and the cavity thereof The top is located at the first closed end, and the cover cavity forms a cavity wall on the circumferential surface between the cavity and the top of the cavity, and the cover body is formed with a bottle mouth joint at the first open end thereof;

An elastic pad is formed such that the elastic pad is integrated with the cavity of the cover body covering the cavity;

a stainless steel lining, the stainless steel lining is received in the covering cavity of the cover body, and the stainless steel lining is positioned against the bottle mouth joint of the cover body, so that the stainless steel lining is set The stainless steel lining is further formed with a joint recess toward one of the first open ends of the lid body between the bottle mouth joint portion and the elastic pad.

The bottle cap structure as described above, wherein the cap body of the cap body is a threaded section formed by the first open end along the length of the cap body to be formed in the cavity wall of the covering cavity.

The cap structure as described above, wherein the stainless steel lining has a chamfered surface formed on a peripheral surface of the sealing recess.

The cap structure as described above, wherein the cap structure further comprises a cover formed with opposite second open ends and second closed ends, and a hollow sleeve cavity is formed therein. The cover cavity of the cover is correspondingly sleeved on the outside of the cover body, and the cover body is formed with a stop edge on the outer wall of the first open end thereof, and the second open end of the cover and the cover body are The stop edge of the outer wall abuts the set position.

The cap structure as described above, wherein the cap is made of a metal material.

The cap structure as described above, wherein the main system of the cap is injection molded from a plastic material, and the elastic mat is made of rubber or edible rubber, so that the elastic mat is formed by secondary injection molding in the cavity of the cover body covering the cavity. At the top, the elastic pad is integrated with the cavity of the cover body covering the cavity.

Thereby, when the creation is covered in the bottle mouth of the bottle body, the stainless steel lining can be adjusted to a proper cover angle with the elastic pad to tightly cover the bottle mouth, whereby the contents of the bottle body are flowed to When the bottle mouth is in contact with the stainless steel sheet, the toxic substance such as plasticizer is not dissolved into the contents, and the elastic mat of the present invention is formed by the second injection molding in the covering cavity of the lid body. The elastic pad is integrated with the top of the cover body covering the cavity, thereby avoiding the presence of the assembly gap between them, so as to improve the health and safety of the contents of the bottle.
