ABSTRACT:
A snap cover hinged to the neck of a collapsible tube such as a tube of toothpaste. The cover is hinged by a plurality of hinge members located to apply spring bias to the cover in both the open and closed positions of the cover so as to maintain the cover in the manually set position. A sleeve collar projects from the top inside face of the cover of a size to fit about the neck of the tube in the closed position so as to restrain contents of the tube from spreading along the inside face of the cover beyond the sleeve.
