Abstract: The rotatable cap of an end closure and the associated end closure base are provided with detent elements defining one rotative position out of the entire 360 degrees and allowing rotation up to such position from all other rotative positions throughout the entire 360 degrees. The detent may be in the form of a plug which is received in and closes the discharge opening of the closure to act as an anti-sifting element. Automatic orientation can be accomplished by simply engaging the cap with a friction member carried at the end of a power-driven spindle provided with a slip clutch while turning the spindle through at least one full turn.

Abstract: A reclosable end cap or closure is provided of the type in which a rotatable disc or cover member is pivotally connected permanently at the center region of the end cap and can be selectively rotated in sliding face-to-face contact to close or unclose openings formed in radially intermediate portions of the end cap. The openings are originally formed as closed, removable, airtight tabs and the rotatable disc is pivoted on a boss upstanding from the center of the end cap to thereby provide a hermetic seal until the closure is first opened, and to provide for reclosability thereafter.

Abstract: A closure for the usual circular array of holes provided in the top wall of a can of cleaner or the like for dispensing the contents of the can. The closure includes a disc overlying the circular array of holes but covering only a minority of the area of the top wall. The disc is divided into a lid portion and a base portion. Protrusions on the underside of the base portion are relatively fixedly retained in their corresponding holes. Protrusions on the underside of the lid portion are relatively releasably retained in their corresponding holes.

Abstract: A closure assembly for a container with a reversible spout for dispensing or storage and having easily manipulated finger grips for assembly and disassembly and releasable locking tabs for resisting disassembly by children. The dispensing spout includes a special base configuration which allows the locking tabs to be effective in resisting disassembly in either position of the spout. Integral lip seal structure affords a positive sealing of relevant elements.

Abstract: An end closure cap for a tape sealed assembly with a cylindrical shell. The closure cap is characterized by a deep dish construction having a high degree of dimensional adaptability making it particularly suited for use with composite shells manufactured with relatively wide dimensional tolerances. The cap includes flared and beveled surfaces which make it self-aligning to the shell and elements which, until completion of the application of a sealing shrink tape, allow escape of air from the shell to facilitate high speed automatic closing of the assembly.
