Synthetic resin liquid container

Abstract

A synthetic resin liquid container for containing drinking water, juice, milk and other liquids is provided. The synthetic resin liquid container has a body that can substantially reduce its volume when a vertical and/or twisting stress is applied to the body, and a form-retaining means to be used after compression of the container body for keeping it compressed.

What is claimed is:  
     
         1 . A synthetic resin liquid container comprising: a container body having an opening, a side wall which is made of a flexible and relatively hard plastic synthetic resin, and a form that facilitate s operation of substantially reducing the volume of the container body by applying a vertical and/or twisting force; 
 cap member for covering the opening; and    retainer means for keeping the reduced volume of the container body.    
     
     
         2 . The synthetic resin liquid container according to  claim 1 , wherein said container body comprises a relatively hard and thin side wall with accordion-shaped contour formed on its surface f or facilitating operation of substantially reducing the volume of container body.  
     
     
         3 . The synthetic resin liquid container according to  claim 2 , wherein said container body comprises sequentially reduced radiuses from both the upper and bottom ends toward the middle of the body.  
     
     
         4 . The synthetic resin liquid container according to  claim 1 , wherein said container body comprises a relatively thin side wall and a number of recesses formed thereon, for facilitating operation of substantially reducing the volume of container.  
     
     
         5 . The synthetic resin liquid container according to  claim 1 , wherein said container body further comprises a belt attached to the opening of the container body, and the belt is in turn connected to a cap, for an aid in keeping the container compressed.  
     
     
         6 . The synthetic resin liquid container according to  claim 1 , wherein said opening of the container body can be embedded into the container body by pressing the opening for keeping the container compressed, for an aid in keeping the container compressed.
