Abstract

A container includes a container body having a short pipe shape in which one end is an open end and the other end is provided with a bottom plate which is formed with a pouring hole and a first sealing member which is joined to an end surface of the open end of the container body to seal the open end.

What is claimed is: 
     
         1 . A container comprising:
 a container body having a short pipe shape in which one end is an open end and the other end is provided with a bottom plate which is formed with a pouring hole; and   a first sealing member which is joined to an end surface of the open end of the container body to seal the open end.   
     
     
         2 . The container according to  claim 1 , wherein the pouring hole has a step shape in which a second end portion that is connected to an outside surface of the bottom plate is larger in opening area than a first end portion that is connected to an inside surface of the bottom plate. 
     
     
         3 . The container according to  claim 2 , wherein the outside surface of the bottom plate is formed with a rib around an edge of the pouring hole in such a manner that the rib surrounds the pouring hole. 
     
     
         4 . The container according to  claim 3 , wherein a tip portion of the rib has a flat surface. 
     
     
         5 . The container according to  claim 1 , wherein an outside surface of the bottom plate is formed with a rib which is distant from an edge of the pouring hole and surrounds the pouring hole. 
     
     
         6 . The container according to  claim 1 , wherein the first sealing member is capable of being broken by pressing the first sealing member. 
     
     
         7 . A portion package comprising:
 the container according to  claim 1 ;   fluid contained in the container; and   a second sealing member which is joined to an outside surface of the bottom plate to seal the pouring hole.   
     
     
         8 . A portion package comprising:
 the container according to  claim 3 ;   fluid contained in the container; and   a second sealing member which is joined to the outside surface of the bottom plate so as to be welded to a tip portion of the rib, and thereby seals the pouring hole.   
     
     
         9 . A manufacturing method of a portion package, comprising:
 pouring fluid through a pouring hole into a short-pipe-shaped container in which one, open end is sealed with a first sealing member and a bottom plate which is provided at the other end is formed with the pouring hole; and   sealing the pouring hole by joining a second sealing member to an outside surface of the bottom plate of the container into which the fluid has been poured.   
     
     
         10 . An opening method of the portion package according to  claim 7 , comprising:
 breaking the first sealing member; and   pushing out the fluid contained in the container by inserting a thing that fits in the container into the container through the open end.   
     
     
         11 . An opening method of the portion package according to  claim 7 , comprising:
 breaking the first sealing member by pressing the first sealing member against a front surface of a thing that fits in the container and is oriented so as to be suitable for insertion into the container.
