Lid and a container assembly having the lid

Abstract

Provided is a lid having a lid body and multiple ribs. The lid body has an extending portion and a connecting portion connected with the extending portion. The extending portion is formed with an opening at one end distal to the connecting portion. The connecting portion protrudes outwardly along the lid's radial direction, and one end of the connecting portion distal to the extending portion dents inwardly to form an annular containing space. Multiple ribs are formed protruding on where the extending portion is adjacent to the connecting portion. Also provided is a container assembly including the lid and a cup body having a cup rim. With one end of the connecting portion distal to the extending portion continuously denting toward inside of the lid body, the cup rim and the connecting portion can be tightly engaged.

What is claimed is: 
     
         1 . A lid, comprising:
 a lid body, having an extending portion and a connecting portion connected with the extending portion, wherein an opening is formed at one end of the extending portion that is distal to the connecting portion, the connecting portion protrudes outwardly along a radial direction of the lid body, and one end of the connecting portion distal to the extending portion dents radially and inwardly to form an annular containing space; and   multiple ribs formed protruding on where the extending portion is adjacent to the connecting portion.   
     
     
         2 . The lid as claimed in  claim 1 , wherein a peripheral edge of a radial cross-section of the extending portion is tapered toward the opening. 
     
     
         3 . The lid as claimed in  claim 1 , wherein a radial cross-section of the lid body is round. 
     
     
         4 . The lid as claimed in  claim 1 , wherein the lid body further has a guide portion connected to one end of the connecting portion that is distal to the extending portion, and the guide portion is in the shape of an annular plate. 
     
     
         5 . The lid as claimed in  claim 1 , wherein the number of the ribs is eight, and the ribs are spaced apart from each other. 
     
     
         6 . The lid as claimed in  claim 2 , wherein the number of the ribs is eight, and the ribs are spaced apart from each other. 
     
     
         7 . The lid as claimed in  claim 3 , wherein the number of the ribs is eight, and the ribs are spaced apart from each other. 
     
     
         8 . The lid as claimed in  claim 4 , wherein the number of the ribs is eight, and the ribs are spaced apart from each other. 
     
     
         9 . A container assembly, comprising:
 the lid as claimed in  claim 1 ; and   a cup body, containing:
 a cup rim, which is set on the connecting portion of the lid body and contained in the annular containing space. 
   
     
     
         10 . The container assembly as claimed in  claim 9 , wherein a peripheral edge of a radial cross-section of the extending portion is tapered toward the opening. 
     
     
         11 . The container assembly as claimed in  claim 9 , wherein a radial cross-section of the lid body is round. 
     
     
         12 . The container assembly as claimed in  claim 9 , wherein the lid body further has a guide portion connected to one end of the connecting portion that is distal to the extending portion, and the guide portion is in the shape of an annular plate. 
     
     
         13 . The container assembly as claimed in  claim 9 , wherein the number of the ribs is eight, and the ribs are spaced apart from each other.
