Sealing container

Abstract

A sealing container in which the container body has a plurality of tapered retaining blocks protruded from the inside wall thereof and equiangularly spaced around the opening in one end of the container body, the sealing cap has a disk-like knob, a hollow cylindrical plug axially extended from the center of one side of the disk-like knob and filled with a desiccant for fitting into the opening of the container body, and an annular retaining flange extended around the periphery of the cylindrical plug for engaging the tapered retaining blocks of the container body and forcing air out of the container body after insertion of the cylindrical plug into the opening of the container body.

What the invention claimed is:  
     
         1 . A sealing container comprising a container body, said container body having an inside wall defining a holding space and an opening, and a sealing cap adapted to seal the opening of the container body, wherein: 
 said container body comprises a plurality of tapered retaining blocks protruded from the inside wall and equiangularly spaced around said opening, said tapered retaining blocks each having a transversely extended and smoothly arched middle convex portion, a sloping guide surface portion and a sloping retaining surface portion respectively extended from said middle convex portion toward the inside wall of said container body at two sides;    said sealing cap comprises a disk-like knob, a cylindrical plug axially extended from the center of one side of said disk-like knob for fitting into the opening of said container body, an annular retaining flange extended around the periphery of said cylindrical plug for engaging the tapered retaining blocks of said container body after insertion of said cylindrical plug into the opening of said container body, said annular retaining flange having a smoothly curved ridge extended on the middle around the periphery of said cylindrical plug, a tapered guide surface portion extended from said smoothly curved ridge toward the periphery of said cylindrical plug at one side for guiding said annular retaining flange over the sloping guide surface portions of said tapered retaining blocks of said container body, and a retaining surface portion extended from said smoothly curved ridge toward the periphery of said cylindrical plug at an opposite side for engaging the sloping retaining surface portions of said tapered retaining blocks of said container body.    
     
     
         2 . The sealing container as claimed in  claim 1 , wherein said container body has a cylindrical shape, and said opening of said container body is formed in one end of said container body.  
     
     
         3 . The sealing container as claimed in  claim 1 , wherein said container body and said sealing cap are respectively injection-molded from plastics.  
     
     
         4 . The sealing container as claimed in  claim 1 , wherein said cylindrical plug of said sealing cap is a hollow structure filled with a desiccant.
