Flexible tube

Abstract

The present invention provides an environment-friendly structure of a flexible tube, comprising a flexible tube, an inner bulk and a cover. After the flexible tube is fulfilled of a material, an inner bulk is disposed to the tail end and then the flexible tube is packaged. Therefore, when using the flexible tube, the flexible tube can provide a better pressing function, and the material in the flexible tube can be squeezed out completely without wasting any material for environmental protection.

What is claimed is: 
     
         1 . an environment-friendly structure of a flexible tube, comprising:
 a flexible tube, comprising an inner hollow part, a tail end for fulfilling a material, and a top end to comprise an opening part;   an inner bulk disposed in the inner hollow part, wherein the inner bulk comprises an inclined plane and a protrusion end extends from the inclined plane;   a cover in a recess shape, comprising an engaging part inside, wherein the engaging part encompasses the opening part.   
     
     
         2 . The structure as claimed in  claim 1 , wherein the protrusion end of the inner bulk and the opening of the flexible tube are in a same shape 
     
     
         3 . The structure as claimed in  claim 1 , wherein an outer radius of the protrusion end of the inner bulk is smaller or equal to an inner radius of the opening of the flexible tube. 
     
     
         4 . The structure as claimed in  claim 1 , wherein the inclined plane of the inner bulk and the top end of the flexible tube are in a same shape. 
     
     
         5 . The structure as claimed in  claim 1 , wherein an outer circumference of the inclined plane of the inner bulk is equal to an inner circumference of the inner hollow part of the flexible tube. 
     
     
         6 . The structure as claimed in  claim 1 , wherein the inner bulk is one-piece formed. 
     
     
         7 . The structure as claimed in  claim 1 , wherein the inner bulk is not one-piece formed. 
     
     
         8 . The structure as claimed in  claim 1 , wherein the inner bulk is made of a rigid material. 
     
     
         9 . The structure as claimed in  claim 1 , wherein the inner bulk is not made of a rigid material.
