ABSTRACT:
Dust covers enclose the upper end of the push-pull bottle cap, the spout cap and the seal which projects through the central hole in the spout cap. The cap is formed with a neck over which the lower end of the dust over fits. The interior of the cover is formed with a plurality of short thread sections (e.g., eight). Above the thread sections is a circumferential locking bead. The cap neck is formed with a plurality of short protrusions (e.g., four) which mesh with the cover thread sections and a circumferential groove above the protuberances into which the locking bead seals. The cover may be pushed down without rotation to seat on the neck and also may be pulled up without rotation for removal. Alternatively, the cover may be twisted on or off, the protuberances meshing with the thread sections when the cover is in closed position its interior is sealed from entry of "wash down" water.
