<p>A reusable contents expeller for collapsible tube which prevents said contents from reverting back into said collapsible tube and that can easily be removed and installed on another tube without the need to firstly insert it through the base of the collapsible tube, said expeller is comprised of an oblong element with two extremities. Said oblong element has a place where it is thin at its thickness and across its breadth so that said place is flexibly pliable to allow said oblong element to fold upon itself to the point where the two said extremities join, thus forming two pressure plates. Said pressure plates are further held and secured together by the use of a hinged flap contiguous and part of one of the said pressure plates. Said flap acts like a hook to secure both pressure plates tightly together. Once closed about a collapsible tube, the contents expeller for collapsible tube expels the contents when it is slid across the length of said tube.</p> |
