Integrated wide-mouth bottle cap with disposable and breakable inner plug

Abstract

The present invention is an integrated wide-mouth bottle cap with a disposable and breakable inner plug comprising a lower cover, an upper cover and an inner plug. The lower cover comprises an opening. The upper cover extends integrally from one side of the lower cover, and the upper cover rotates relatively to the lower cover to fasten the lower cover and seals the opening. The inner plug integrally extends from the lower cover adjacent to the periphery of opening and seals the opening. The inner plug comprises a tearing zone between the inner plug and the lower cover, the inner plug comprises a tearing member for a user to pull in order to drive the inner plug displacement relative to the lower cover, so as to disengage the inner plug from the lower cover and expose the opening by tearing off the tearing zone.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a wide-mouth bottle sealing cap, and more particularly to an integrated wide-mouth bottle cap with a disposable and breakable inner plug.BACKGROUND OF THE INVENTION[0002]For example, the Chinese patent publication no. CN204916566U “wide-mouth bottle” discloses a wide-mouth bottle comprising a bottle, a cap and an inner plug, wherein the inner plug and the cap are separated, the inner plug is disposed on an opening of the bottle, and the inner plug includes an inner plug ring, an inner plug tab and a tear tab. The inner plug seals the opening of the bottle, and the opening of the bottle may only be opened after pulling the tear tab to break and remove the inner plug tab. It is designed as a disposable and breakable sealing cover, thus preventing a user from arbitrarily taking the contents inside the bottle before purchase in order to avoid contaminating the contents inside the bottle.[0003]However, as described structures a...

AI Technical Summary

Benefits of technology

The present invention aims to provide a low-cost bottle cap that reduces contamination and meets environmental protection requirements. Specifically, the cap has an integrated lower cover, upper cover, and inner plug, which can be made from a single material, reducing processing procedures and manufacturing costs. Additionally, the inner plug helps prevent contamination and there is no recycling problem as materials can be easily sorted to meet requirements.

Problems solved by technology

However, as described structures above, since the cap and the inner plug are two separate components that need to be separately assembled on the bottle, which results in additionally adding an extra processing procedure for the assembly, and significantly increasing the labor and costs required for manufacturing, and the added procedure will not only increase the risk of contamination, but also cause leakage when the assembly is poor.

Furthermore, since the cap and the inner plug are manufactured separately, and the materials of the cap and the inner plug are different, there will be problems of twofold material preparation and storage, and the sorting will be troublesome when recycling.
