ABSTRACT A double-seal, molded plastic screw cap for use with a solid cosmetic product, consisting of a resil- ient, cup-shaped plastic cap body having internal screw threads, the bottom rim of the body being engageable with an external shoulder of the container to effect a seal therewith. Above the screw threads, the side wall of the body has an inwardly raised, annular sealing bead adapted to slidingly and telescopically engage an outer annular surface of the container neck at the top rim thereof, to effect a second seal. A clearance chamber exists above the sealing bead, into which a portion of the cosmetic product can extend. The clearance chamber is characterized by thin walls, to effect a saving of plastic material. The sealing bead is effective indepen- dent of the exact axial positioning of the cap, and the bottom rim seal of the cap requires that the latter be tightly screwed onto the container. The advantage of the present construction over the devices of the prior art is that an improved seal is effected, while at the same time the overall manufacturing cost is reduced by the maximum extent possible.
