<p>A device for removing a desired quantity of a pasty substance contained in a flexible tube comprising an integral structure including two elongated members (7) at least one of which is resilient, connected by a frame (8), said elongated members (7) defining an opening which gradually narrows from a relatively wide entrance (2) to a narrow slot (3), exerting pressure on the tube in the collapsed state, said elongated members (7) being separated from the connecting frame (8) by a second slot (11) permitting a resilient movement of at least one of said elongated members (7), whereby a desired quantity of the content of the tube (100) may be expelled therefrom by pressing said two elongated members (7) toward each other and/or forward. <IMAGE></p> |
