Receptacle with covers

Abstract

A receptacle includes a main body and first and second covers. The main body includes a bottom wall, and a surrounding wall extending upward from a periphery of the bottom wall and having a substantially flat top annular face on a top periphery thereof. The first cover covers tightly the main body, and includes a first cover portion abutting fittingly against the top annular face of the surrounding wall, and a first peripheral portion surrounding the top periphery of the surrounding wall. The second cover includes a second cover portion covering the first cover portion, a second peripheral portion surrounding the first peripheral portion, and an annular pressing shoulder formed between the second cover portion and the second peripheral portion to press the first cover against the top annular face of the surrounding wall.

1 . A receptacle comprising:
 a main body including a bottom wall, and a surrounding wall extending upward from a periphery of said bottom wall, said surrounding wall having a substantially flat top annular face on a top periphery thereof;   a first cover made of a flexible plastic material and covering tightly said main body, said first cover including a first cover portion abutting fittingly against said top annular face of said surrounding wall, and a first peripheral portion extending downward from a periphery of said first cover portion and surrounding said top periphery of said surrounding wall; and   a second cover including a second cover portion covering said first cover portion, a second peripheral portion extending downward from a. periphery of said second cover portion and surrounding said first peripheral portion, and an annular pressing shoulder formed between said second cover portion and said second peripheral portion to press said first cover against said top annular face of said surrounding wall.   
     
     
         2 . The receptacle of  claim 1 , wherein said surrounding wall has a largest outer diameter dimensioned to fit into an inner diameter of said first peripheral portion. 
     
     
         3 . The receptacle of  claim 1 , wherein said first peripheral portion has an outer diameter dimensioned to fit into an inner diameter of said second peripheral portion. 
     
     
         4 . The receptacle of  claim 1 , wherein said top annular face of said surrounding wall has a width occupying 1/19 of a largest outer diameter of said surrounding wall. 
     
     
         5 . The receptacle of  claim 1 , wherein each of said bottom wall and said surrounding wall is hollow, and has an insulation space. 
     
     
         6 . The receptacle of  claim 1 , wherein said first cover further includes a deformable indentation formed in a corner between said first cover portion and said first peripheral portion to receive said top periphery of said surrounding wall. 
     
     
         7 . The receptacle of  claim 1 , wherein said first cover is made of polypropylene. 
     
     
         8 . The receptacle of  claim 1 , wherein said main body further includes an ear portion projecting outwardly from said first peripheral portion. 
     
     
         9 . The receptacle of  claim 1 , wherein said main body further includes a support ring projecting from a bottom face of said bottom wall. 
     
     
         10 . The receptacle of  claim 9 , wherein said second cover further includes a limiting ring projecting from a top face of said second cover portion and having an inner diameter larger than an outer diameter of said support ring. 
     
     
         11 . The receptacle of  claim 1 , wherein said main body further includes a guide curved face formed on an inner surface of said surrounding wall and extending downward from said flat top annular face.
