Foam delivering container and method for charging contents into the same

Abstract

A foam discharge container 1 including: a flexible body portion 2 to be filled with contents having foaming properties; an ejection port 2 a formed in the body portion 2 for discharging the contents therefrom when the body portion 2 is gripped; foaming elements 4 a to 4 c housed in the body portion 2 and having elasticities. This foam discharge container 1 can suppress the container cost at a low level, can be simply finished and can have an excellent portability.

1 . A foam discharge container for foaming and discharging contents in a liquid state, characterized by comprising: contents containing a surface active agent and water and having foaming properties; a soft and tubular body portion filled with said contents; an ejection port formed in said body portion for discharging the contents therethrough when said body portion is gripped; and at least one foaming element housed in said body portion and having an elasticity.  
     
     
         2 . A foam discharge container as set forth in  claim 1 , wherein said ejection port is protruded in a cylindrical shape from the body portion, and wherein the foaming element is absent from the inside of cylindrical portion of said ejection port.  
     
     
         3 . A foam discharge container as set forth in  claim 1  or  2 , wherein the foaming element is present at least near the ejection port.  
     
     
         4 . A foam discharge container as set forth in  claim 1  or  2 , wherein the foaming density of the foaming element is higher at a portion near the ejection port than at the portion other than the near portion.  
     
     
         5 . A foam discharge container as set forth in  claim 3 , wherein the foaming density of the foaming element is higher at a portion near the ejection port than at the portion other than the near portion.  
     
     
         6 . A foam discharge container as set forth in  claim 4 , wherein three foaming elements are housed in the body portion, and wherein the adjoining foaming elements have different densities.  
     
     
         7 . A foam discharge container as set forth in  claim 5 , wherein three foaming elements are housed in the body portion, and wherein the adjoining foaming elements have different densities.  
     
     
         8 . A foam discharge container as set forth in  claim 1  or  2 , further comprising a cylindrical portion protruded to the bottom of the body portion from the portion where the ejection port and the body portion are connected to each other, for providing a discharge passage.  
     
     
         9 . A foam discharge container as set forth in  claim 3 , further comprising a cylindrical portion protruded to the bottom of the body portion from the portion where the ejection port and the body portion are connected to each other, for providing a discharge passage.  
     
     
         10 . A foam discharge container as set forth in  claim 4 , further comprising a cylindrical portion protruded to the bottom of the body portion from the portion where the ejection port and the body portion are connected to each other, for providing a discharge passage.  
     
     
         11 . A foam discharge container as set forth in any of  claims 5  to  7 , further comprising a cylindrical portion protruded to the bottom of the body portion from the portion where the ejection port and the body portion are connected to each other, for providing a discharge passage.  
     
     
         12 . A foam discharge container as set forth in  claim 1  or  2 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         13 . A foam discharge container as set forth in  claim 3 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         14 . A foam discharge container as set forth in  claim 4 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         15 . A foam discharge container as set forth in any of  claims 5  to  7 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         16 . A foam discharge container as set forth in  claim 8 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         17 . A foam discharge container as set forth in  claim 9  or  10 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         18 . A foam discharge container as set forth in  claim 11 , wherein the body portion is transparent or semitransparent, and wherein the color of the foaming element is different from that of the contents filled into the body portion.  
     
     
         19 . A method of filling a foam discharge container with contents, characterized by comprising: the step of inserting at least one foaming element having an elasticity, from an opening formed in the bottom portion of a soft and tubular body portion; the step of filling the contents containing a surface active agent and water and having foaming properties, from said opening; and the step of closing said opening.
