Method for making a container from moldable material and a container from moldable material

Abstract

This invention is a method for the manufacture of a container made of moldable material having at least one side wall, a base and a filling opening, characterized by the fact that said container is manufactured by molding, and by the fact that at least one of its side walls comprises, near said filling opening, first means forming a hinge and second means forming a hinge located at some distance from said first means forming a hinge and making it possible to pivot a part of said side wall, thereby creating a triple wall, as well as to the containers that can be obtained by using said method.

We claim  
     
         1 . A method for manufacturing a container made of moldable material having at least one side wall, a base, and a filling opening, comprising the steps of: 
 molding said container such that at least one of said side walls includes, near said filling opening, a first means forming a hinge and a second means forming a hinge located at some distance from said first means forming the hinge; and    pivoting a part of said at least one of said side walls around said hinges to create a triple wall.    
     
     
         2 . The method as claimed in  claim 1 , wherein said container is molded by injection molding or by extrusion-blowing.  
     
     
         3 . The method as claimed in  claim 1 , wherein said first means forming the hinge and second means forming the hinge include two lines that are thinner than the rest of said one of said side walls or two sets of lines connected to one another by very small walls in an appropriate shape.  
     
     
         4 . The method as claimed in  claim 1 , wherein said at least one of said side walls also has a horizontal peripheral groove or channel, said groove or channel includes along an upper part a thinner line forming a hinge extended by a band of material, 
 further including the step of, if necessary, cutting off a portion of said container above said band before pivoting said part around said hinge, thereby closing said groove or channel in whole or in part.    
     
     
         5 . The method as claimed in  claim 4 , further including the step of welding said band to an inside wall of said container after pivoting said part.  
     
     
         6 . The method as claimed in  claim 1 , wherein two containers are molded simultaneously, and 
 further including the steps of: 
 molding a second container extending from said container to form a single shape such that said at least one of said side walls of said second container extends from said at least one of said side walls of said container, said base of said second container being opposed said base of said container; and  
 cutting said shape at approximately a middle and parallel to said bases to form said container and said second container.  
   
     
     
         7 . A container made from moldable material, comprising: 
 a base;    at least one side wall extending from said base, and    a filling opening opposed said base,    wherein at least one of said side walls includes, near said filling opening, a first means forming a first hinge such that a part of said at least one of said side walls is pivotable around said first hinge to create a wall.    
     
     
         8 . The container as claimed in  claim 7 , wherein said at least one of said side walls further includes a second means forming a second hinge located at some distance from said first means forming said first hinge such that said part of said at least one of said side walls is pivotable around said first hinge and said second hinge.  
     
     
         9 . The container as claimed in  claim 8 , wherein said first means forming the hinge and said second means forming the hinge include two lines that are thinner than the rest of said at least one of said side walls or two sets of lines connected to one another by very small walls in an appropriate shape.  
     
     
         10 . The container as claimed in  claim 7 , wherein: 
 said at least one of said side walls of said container includes a horizontal peripheral groove or channel, said groove or channel includes along an upper part a thinner line forming said first hinge extended by a band of material, and    if necessary, a portion of said container above said band is cut off before pivoting said part around said hinge, thereby closing said groove or channel in whole or in part.    
     
     
         11 . The container as claimed in  claim 10 , wherein said band is attached to an inside wall of said container after said band has been pivoted to close said groove or channel.  
     
     
         12 . The container as claimed in  claim 7 , further including: 
 a second container including 
 at least one second side wall extending from said at least one side wall of said container, said at least one second side wall including, near said filling opening, a first means forming a hinge;  
 a second base extending from said at least one second side wall and being opposed said base of said container;  
 a second filling opening opposed said second base,  
 wherein two containers are formed when said second container is separated from said container at an approximate mid-point between said base and said second base.  
   
     
     
         13 . The container as claimed in  claim 8 , further including: 
 a second container including 
 at least one second side wall extending from said at least one side wall of said container, said at least one second side wall including, near said filling opening, a first means forming a hinge and a second means forming a second hinge located at some distance from said first means forming said first hinge;  
 a second base extending from said at least one second side wall and being opposed said base of said container;  
 a second filling opening opposed said second base,  
 wherein two containers are formed when said second container is separated from said container at an approximate mid-point between said base and said second base.  
   
     
     
         14 . A method for manufacturing a container made of moldable material having at least one side wall, a base, and a filling opening, comprising the steps of: 
 molding said container such that at least one of said side walls includes, near said filling opening, a first means forming a first hinge; and    pivoting a part of said at least one of said side walls around said first hinge to create a wall.    
     
     
         15 . The method as claimed in  claim 14 , wherein said at least one of said side walls also has a horizontal peripheral groove or channel, said groove or channel includes along an upper part a thinner line forming said first hinge extended by a band of material, 
 further including the step of, if necessary, cutting off a portion of said container above said band before pivoting said part around said first hinge, thereby closing said groove or channel in whole or in part.    
     
     
         16 . The method as claimed in  claim 15 , further including the step of welding said band to an inside wall of said container after pivoting said part.  
     
     
         17 . The method as claimed in  claim 14 , wherein: 
 the step of molding said container further includes molding said at least one of said side walls to further include a second means forming a second hinge located at some distance from said first means forming said first hinge, and    said step of pivoting said part also includes pivoting said part around said second hinge.    
     
     
         18 . The method as claimed in  claim 14 , wherein said container is molded by injection molding or by extrusion-blowing.  
     
     
         19 . The method as claimed in  claim 14 , wherein two containers are molded simultaneously, and 
 further including the steps of: 
 molding a second container extending from said container to form a single shape such that said at least one of said side walls of said second container extends from said at least one of said side walls of said container, said base of said second container being opposed said base of said container; and  
 cutting said shape at approximately a middle and parallel to said bases to form said container and said second container.
