Container and a cover having a sealing structure

Abstract

A container and a cover having a sealing structure includes: the container including a bottom and a side wall having one end connected to the bottom to form a space, and another end of the side wall that is not connected to the bottom is an open end, the side wall having an inner surface and an outer surface, the inner surface faces the space, and the inner surface has a first hook portion; and the cover disposed at the open end of the container, the cover has a covering portion and a second hook portion, the covering portion covers the open end, and the second hook portion is hooked on the first hook portion. The covering portion tightly covers the open end, and the second hook portion is hooked to the first hook portion, so that the coupling between the cover and the container is more stable.

What is claimed is: 
     
         1 . A container and a cover having a sealing structure, comprising:
 the container including a bottom and a side wall having one end connected to the bottom to form a space, and another end of the side wall that is not connected to the bottom is defined as an open end, the side wall having an inner surface and an outer surface, the inner surface faces the space, the outer surface is opposite to the inner surface, and the inner surface has a first hook portion;   the cover disposed at the open end of the container and made of a flexible material, wherein the cover has a covering portion and a second hook portion, the covering portion covers the open end, and the second hook portion is hooked on the first hook portion;   the covering portion including a top section and an inner section connected one another in sequence, the inner section is abutted against the inner surface to generate a fastening force;   the cover having an abutting portion connected to the inner section, the abutting portion has an abutting surface facing the inner surface of the side wall, and the second hook portion is connected to the abutting portion;   the abutting surface and the inner surface are abutted against each other or separated as a pressure in the container changes.   
     
     
         2 . The container and the cover having the sealing structure as claimed in  claim 1 , wherein covering portion further includes an outer section, the outer section is abutted against the outer surface. 
     
     
         3 . The container and the cover having the sealing structure as claimed in  claim 2 , wherein a distance between the outer section and the inner section is a first distance, a width of the side wall is a second distance, an insertion space is defined between the outer section and the inner section, before the cover is placed on the container, the first distance is smaller than the second distance. 
     
     
         4 . The container and the cover having the sealing structure as claimed in  claim 2 , wherein the open end has an end surface connected between the inner surface and the outer surface, the covering portion has a covering surface abutted against the end surface, and the covering surface is located on the top section. 
     
     
         5 . The container and the cover having the sealing structure as claimed in  claim 3 , wherein the open end has an end surface connected between the inner surface and the outer surface, the covering portion has a covering surface abutted against the end surface, and the covering surface is located on the top section. 
     
     
         6 . The container and the cover having the sealing structure as claimed in  claim 1 , wherein the first hook portion has a first stop surface which faces the bottom, and the second hook portion has a second stop surface which is abutted against the first stop surface. 
     
     
         7 . The container and the cover having the sealing structure as claimed in  claim 2 , wherein the first hook portion has a first stop surface which faces the bottom, and the second hook portion has a second stop surface which is abutted against the first stop surface. 
     
     
         8 . The container and the cover having the sealing structure as claimed in  claim 3 , wherein the first hook portion has a first stop surface which faces the bottom, and the second hook portion has a second stop surface which is abutted against the first stop surface. 
     
     
         9 . The container and the cover having the sealing structure as claimed in  claim 1 , wherein the first hook portion and the second hook portion are a concave-convex combination. 
     
     
         10 . The container and the cover having the sealing structure as claimed in  claim 2 , wherein the first hook portion and the second hook portion are a concave-convex combination. 
     
     
         11 . The container and the cover having the sealing structure as claimed in  claim 3 , wherein the first hook portion and the second hook portion are a concave-convex combination. 
     
     
         12 . The container and the cover with having the sealing structure as claimed in  claim 1 , wherein the open end has a fixing ring which is made of a metal material. 
     
     
         13 . The container and the cover having the sealing structure as claimed in  claim 2 , wherein the open end has a fixing ring which is made of a metal material. 
     
     
         14 . The container and the cover having the sealing structure as claimed in  claim 3 , wherein the open end has a fixing ring which is made of a metal material.
