Bottles for flowable adhesive

Abstract

A bottle for flowable adhesive includes an outer tube made of soft metal and an inner tube made from a material that allows the inner tube to restore its original shape when an external squeezing force applied to the outer tube is released. The inner tube has an outer diameter the same as an inner diameter of the outer tube, with an outer peripheral face of the inner tube being in intimate contact with an inner peripheral face of the outer tube. When the outer tube is squeezed, the flowable adhesive contained in the inner tube is dispensed through the spout of the dispensing member. The outer tube restores its original shape when the external squeezing force applied to the outer tube is released, as the inner tube pushes the outer tube outwardly when the inner tube is restoring its original shape.

What is claimed is:  
     
         1 . A bottle for flowable adhesive comprising: 
 an outer tube made of soft metal; and    an inner tube made from a material that allows the inner tube to restore its original shape when an external squeezing force applied to the outer tube is released, the inner tube having an outer diameter the same as an inner diameter of the outer tube, with an outer peripheral face of the inner tube being in intimate contact with an inner peripheral face of the outer tube.    
     
     
         2 . The bottle for flowable adhesive as claimed in  claim 1 , wherein the outer tube includes a mouth with an outer threading for threading engagement with an inner threading of a dispensing member.  
     
     
         3 . The bottle for flowable adhesive as claimed in  claim 1 , wherein the inner tube includes at least one opening in a periphery thereof.  
     
     
         4 . The bottle for flowable adhesive as claimed in claim  1 m wherein the inner tube includes at least one cutout in a periphery thereof.
