Metal container with a base

Abstract

A metal container includes a metal tubular body, a metal base, and a coupling member. A stop is formed on an inner periphery delimiting a bottom opening of the tubular body. The base includes a receiving portion on a top thereof for coupling with a bottom end of the tubular body. An abutting portion extends inward from the receiving portion. The coupling member is mounted in the base and the tubular body. The coupling member includes a tubular wall and a bottom wall. An outer flange extends radially outward from the bottom wall. The coupling member further includes a plurality of protrusions on an outer periphery of the tubular wall. The stop of the tubular body and the abutting portion of the base are sandwiched between the protrusions such that the bottom end of the tubular body is reliably received in the receiving portion of the base.

1 . A metal container comprising: 
 a metal tubular body having a top opening in a top end thereof and a bottom opening in a bottom end thereof, a stop being formed on an inner periphery delimiting the bottom opening;    a metal base including a receiving portion on a top thereof for coupling with the bottom end of the metal tubular body, an abutting portion extending inward from the receiving portion; and    a coupling member mounted in the metal base and the metal tubular body, the coupling member including a tubular wall and a bottom wall, an outer flange extending radially outward from the bottom wall, the coupling member further including a plurality of protrusions on an outer periphery of the tubular wall;    wherein the stop of the metal tubular body and the abutting portion of the metal base are sandwiched between the protrusions such that the bottom end of the metal tubular body is reliably received in the receiving portion of the metal base.    
   
   
       2 . The metal container as claimed in  claim 1 , wherein the stop is a bent extending and bending inward from a bottom end face of the metal tubular body.  
   
   
       3 . The metal container as claimed in  claim 1 , wherein the abutting portion is an annular ledge extending inward and then downward and outward from the receiving portion of the metal base.  
   
   
       4 . The metal container as claimed in  claim 3 , wherein the annular ledge includes an upper edge on which the bottom end of the metal tubular body rests and a lower edge resting on the outer flange of the coupling member.  
   
   
       5 . The metal container as claimed in  claim 1 , wherein the coupling member is made of plastic.  
   
   
       6 . The metal container as claimed in  claim 1 , wherein the coupling member has a maximum outer diameter approximately the same as an inner diameter of the metal tubular body.  
   
   
       7 . The metal container as claimed in  claim 1 , wherein the protrusions are wedges each having an inclined guiding face for guiding the coupling member into the metal tubular body and a bottom face abutting against the stop of the metal tubular body.  
   
   
       8 . The metal container as claimed in  claim 1 , wherein the protrusions extend downward and outward from the outer periphery of the tubular wall, with a distal end of each said protrusion spaced from the tubular wall, each said protrusion having an inclined guiding face for guiding the coupling member into the metal tubular body and a bottom face abutting against the stop of the metal tubular body.  
   
   
       9 . The metal container as claimed in  claim 7 , wherein a distance between the bottom face of each said protrusion and the outer flange is equal to a sum of a height of the abutting portion of the metal base and a height of the stop of the metal tubular body.  
   
   
       10 . The metal container as claimed in  claim 8 , wherein a distance between the bottom face of each said protrusion and the outer flange is equal to a sum of a height of the abutting portion of the metal base and a height of the stop of the metal tubular body.  
   
   
       11 . The metal container as claimed in  claim 5 , wherein the coupling member has a maximum outer diameter approximately the same as an inner diameter of the metal tubular body.  
   
   
       12 . The metal container as claimed in  claim 5 , wherein the protrusions are wedges each having an inclined guiding face for guiding the coupling member into the metal tubular body and a bottom face abutting against the stop of the metal tubular body.  
   
   
       13 . The metal container as claimed in  claim 5 , wherein the protrusions extend downward and outward from the outer periphery of the tubular wall, with a distal end of each said protrusion spaced from the tubular wall, each said protrusion having an inclined guiding face for guiding the coupling member into the metal tubular body and a bottom face abutting against the stop of the metal tubular body.
