Plunger tube

Abstract

The plunger tube includes a flexible tubular housing having a closed bottom and a top, the top including an opening allowing contents of the tube to be dispensed therefrom. A feed plunger is permanently disposed inside the tubular housing, the feed plunger having dual tapered wiping blades that hug the tube inner walls to aid in dispensing contents adhered to the tube walls. The wiping blades also prevent the plunger from sliding out of axial alignment with the tube. A tube cap is removably disposed on the top to seal and alternatively unseal the opening in the top. When a user squeezes and displaces the plunger upward from the outside of the tube, a corresponding amount of tube contents is forcibly ejected through the top opening. Advantageously, the internal plunger assists in complete usage of the tube contents.
