COVER TO BE ATTACHED TO CONTAINER, AEROSOL TYPE PRODUCT, AND PUMP-TYPE PRODUCT EQUIPPED WITH THE COVER

摘要

PROBLEM TO BE SOLVED: To provide a cover structure with both a reliable coupling function with a container and a decoupling function when positively pressing an operate-to-remove part.;SOLUTION: The cover 10 consists of a pressing part 13b for removing it and a tube 11 having fitting projections 12a to 12d (with small fitting force) and 12e to 12g (with large fitting force) with a container side. A part formed with the pressing part 13b (separate peripheral surface 13a) is usually separate from a mountain cap 22. When the pressing part 13b is pushed inward and upward, the separate peripheral surface 13a is displaced inward by a distance of the separation, and its peripheral edges (peripheral edges 14a and 14b of a contact peripheral surface 14) accept the force in the shown widening direction. Thus the fitting force between the cover 10 and the container 20 gets weaker. On the other hand, upward strong pressing force from an operator is directly applied to the tapered pressing part 13b, whereby the cover 10 is removed from the container 20 by the upward pressing and widening operations.;COPYRIGHT: (C)2004,JPO
