Cup with Elastic Cover

Abstract

A cup includes a cup body and an elastic cover. The elastic cover includes an elastic strip having a first end mounted on the cup body and a cover body mounted on a second end of the elastic strip and removably mounted on the top of the cup body. The cover body has a mounting plate abutting the top of the cup body. The mounting plate has an inner wall provided with a plurality of pressing bosses pressing the top of the cup body. Thus, the cup body is compressed inward, the top of the cup body is released from the pressing bosses, and the cover body is moved outwardly relative to the cup body by the elastic action of the elastic strip so that the cover body is detached from the top of the cup body automatically.

1 . A cup, comprising:
 a cup body;   an elastic cover mounted on a top of the cup body to cover the top of the cup body,   wherein the elastic cover includes:   an elastic strip having a first end mounted on the top of the cup body;   a cover body mounted on a second end of the elastic strip and removably mounted on the top of the cup body.   
     
     
         2 . The cup of  claim 1 , wherein the cover body of the elastic cover has a downward extending mounting plate abutting the top of the cup body. 
     
     
         3 . The cup of  claim 2 , wherein the mounting plate of the cover body has an inner wall provided with a plurality of pressing bosses pressing the top of the cup body to releasably lock the mounting plate of the cover body onto the top of the cup body. 
     
     
         4 . The cup of  claim 3 , wherein the mounting plate of the cover body has a peripheral wall provided with an elongate opening. 
     
     
         5 . The cup of  claim 1 , wherein the elastic cover  1  further includes:
 a mounting ring secured on the first end of the elastic strip and mounted on the top of the cup body to attach the elastic strip to the top of the cup body.   
     
     
         6 . The cup of  claim 1 , wherein
 the first end of the elastic strip is directly secured on the top of the cup body;   the elastic strip and the top of the cup body are combined integrally.   
     
     
         7 . The cup of  claim 4 , wherein a deformed portion of the top of the cup body is movable to protrude outwardly from the opening of the mounting plate when the cup body is compressed inward so as to allow an inward compression of the cup body. 
     
     
         8 . The cup of  claim 1 , wherein the elastic cover is detachably mounted on the cup body. 
     
     
         9 . The cup of  claim 1 , wherein the cup body is made of a flexible material. 
     
     
         10 . The cup of  claim 1 , wherein the cover body of the elastic cover is a circular hollow body. 
     
     
         11 . The cup of  claim 1 , wherein the cover body of the elastic cover has a substantially inverted U-shaped cross-sectional profile. 
     
     
         12 . The cup of  claim 1 , wherein
 the cover body of the elastic cover is movable in concert with the second end of the elastic strip;   the cover body of the elastic cover is movable outwardly relative to the top of the cup body by an elastic action of the elastic strip of the elastic cover.   
     
     
         13 . The cup of  claim 4 , wherein the opening of the mounting plate faces the elastic strip. 
     
     
         14 . The cup of  claim 4 , wherein the opening of the mounting plate is located between the pressing bosses of the mounting plate. 
     
     
         15 . The cup of  claim 4 , wherein the pressing bosses of the mounting plate are arranged at two opposite sides of the elastic strip. 
     
     
         16 . The cup of  claim 4 , wherein the pressing bosses of the mounting plate are arranged at two opposite sides of the opening of the mounting plate. 
     
     
         17 . The cup of  claim 1 , wherein the elastic strip of the elastic cover is an elongate flat sheet plate. 
     
     
         18 . The cup of  claim 1 , wherein the elastic strip of the elastic cover is disposed at an upright state. 
     
     
         19 . The cup of  claim 1 , wherein the elastic strip of the elastic cover is located between the pressing bosses of the mounting plate. 
     
     
         20 . The cup of  claim 5 , wherein the mounting ring of the elastic cover is detachably mounted on the top of the cup body.
