ABSTRACT:
A device for removing a desired quantity of a pasty substance contained in a flexible tube. The device comprises an integral structure including two elongated members at least one of which is resilient, connected by a frame. The elongated members define an opening which gradually narrows from a relatively wide entrance to a narrow slot, and are each separated from the connecting frame by a second slot permitting a resilient movement of at least one of said elongated members. A desired quantity of the content of the tube may be expelled by pressing the two elongated members toward each.
