Cover structure

Abstract

A cover structure is disclosed. When an annular sealing portion of a cover body is engaged with a container, a sealing section of the annular sealing portion abuts against an annular inner surface of the container, and then, a folding section of the annular sealing portion is folded to a sealing state, so that part of the folding section abuts against the annular outer surface of the container to form a dual leak-proof sealing structure. The folding section of the annular sealing portion is an annular elastic and full-peripheral tightening structure. Therefore, the sealing between the container and the cover may be strengthened for a good sealing effect, and preventing liquid in the container from being splashed on clothes, bags or surrounding articles. When the cover structure is in use, as long as the folding section is in the unsealing state, the cover can be separated from the container, which is convenient to carry and use.

Description

Technical field [0001] The present invention is related to the structure of the cover, in particular, refers to a cover structure that is tightly engaged with the container. Background technique [0002] Please refer to China Taiwan Patent (M301862) related to a display container, which mainly includes a container body and a base, and a fitting portion is provided at the bottom of the container body, and the top end of the base is provided with a joint portion and in the joint portion. The fitting portion embedded at the bottom of the container body, such a container having a base, can be placed on the display stand for display; the base is separated from the container body, can also The base cover is held at the top opening of the container body to form the use of the cover to avoid spilling out of the liquid. [0003] However, at the top opening of the container body, the base is lifted at the top opening of the container body, which is due to insufficient, resulting in still a...

Problems solved by technology

[0003] However, when the base is used to cover the top opening of the container body, the tightness is quite insufficient, resulting in gaps. If it is shaken or tilted, the liquid in the container body will easily overflow , it cannot meet the demand of tight cover in use; moreover, the structure of the base cover in the past is usually only suitable for indoor use, and cannot be carried out for use outside. inconvenient

[0004] There is also a general lunch box and cover fastening structure, such as: Lock and Lock, in order to extend the buckle hooks at the four corners of the cover body, the ends of the buckle hooks form different shapes of buckles, and the lunch box is relatively equipped with Fastening structure, such a fastening structure, the four corner structures are independent, and must be fastened individually, so that the lid can be tightly fitted to the opening of the lunch box. If any fastening structure is not buckled, it will not be tightly sealed Possibility; and the above four fastening structures can only be used as fastening structures without other functions, and there is a need for improvement
