Claims5
A hand-operated disposable device for controllably dispensing substances having a paste-like or cream-like consistency comprising:
- a) a transparent plastic container member having a smooth exterior surface and a cylindrical bore elongated upon a straight axis between open leading and trailing extremities and having a smooth interior surface and demarcation means in the form of annular grooves fashioned within said interior surface and disposed at spaced intervals along said axis to denote successive regions within said bore of known volume, and
- b) a plunger member elongated between forward and rearward extremities and removably associated with said container member by way of slidable engagement with said bore upon a common axis, said forward extremity having a transverse force-applying surface and a surrounding outwardly protruding wiping lip, and said rearward extremity having abutment means to limit forward movement of said plunger member by way of abutment with the trailing extremity of said container member.
