Spray can

Abstract

A spray can has a first body, a second body, and a reinforcing sleeve. The first body is made of plastic. The second body is made of plastic and is connected to the first body. The reinforcing sleeve is made of metal. The reinforcing sleeve is sleeved on the second body and is adjacent to a joining portion where the second body is connected to the first body. The first body and the second body made of plastic save a lot of material and machining expenses. The reinforcing sleeve8 ade of metal enhances the rigidity of the joining portion of the first body and. the second body.

What is claimed is: 
     
         1 . A spray can comprising:
 a first body made of plastic;   a second body made of plastic and connected to the first body; and   a reinforcing sleeve made of metal, sleeved on the second body, and disposed adjacent to a joining portion where the second body is connected to the first body.   
     
     
         2 . The spray can as claimed in  claim 1 , wherein
 the first body has
 an outer circumference; 
 a first end; 
 a second end opposite to the first end of the first body; 
 an assembling portion disposed at the first end of the first body; and 
 an annular abutting portion adjacent to the first end of the first body; and 
   the second body and the reinforcing sleeve abut against the annular abutting portion of the first body.   
     
     
         3 . The spray can as claimed in  claim 2 , wherein the second body has a connecting portion screwed with the assembling portion of the first body. 
     
     
         4 . The spray can as claimed in  claim 3 , wherein
 the second body has
 an exterior circumference; 
 a first end; 
 a second end opposite to the first end of the second body; and 
 at least one engaging ring disposed on the exterior circumference of the second body and adjacent to the second end of the second body; and 
   the reinforcing sleeve has
 an interior circumference; and. 
 at least one engaging groove being annular, disposed on the interior circumference of the reinforcing sleeve, and respectively engaging with the at least one engaging ring. 
   
     
     
         5 . The spray can as claimed in  claim 4 , wherein
 the at least one engaging ring comprises two engaging rings; and   the at least one engaging groove comprises two engaging grooves.   
     
     
         6 . The spray can as claimed in  claim 1 , wherein
 the second body is made by molding; and   the reinforcing sleeve is connected to and fixed on the second body when the second body is being molded.   
     
     
         7 . The spray can as claimed in  claim 2 , wherein
 the second body is made by molding; and   the reinforcing sleeve is connected to and fixed on the second body when the second body is being molded.   
     
     
         8 . The spray can as claimed in  claim 3 , wherein
 the second body is made by molding; and   the reinforcing sleeve is connected to and fixed on the second body when the second body is being molded.   
     
     
         9 . The spray can as claimed in  claim 4 , wherein
 the second body is made by molding; and   the reinforcing sleeve is connected to and fixed on the second body when the second body is being molded.   
     
     
         10 . The spray can as claimed in  claim 5 , wherein
 the second body is made by molding; and   the reinforcing sleeve is connected to and fixed on the second body when the second body is being molded.
