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.

Claims

1. In a reclosable closure for the circular array of holes which is provided in the top wall of cleanser cans and the like for dispensing the powdered product contained in the can, a plastic disc overlying all said holes of said array but overlying only a minority of the total area of said top wall, said disc being generally concentric with said array and being hinged along a chord line and being relatively rigid at other locations, said chord line overlying no portion of any of said holes of said array but rather dividing said disc into (1) a lid area overlying the entireties of the members of a first sub-array of said holes comprising a majority of the members of said circular array of holes and (2) a base area overlying the entireties of the members of a second sub-array of said holes comprising the remaining minority of the members of said circular array of holes, a circular array of protrusions on the underside of the plastic disc matching said circular array of holes and respectively receivable in the members of said circular array of holes in one-to-one correspondence, said circular array of protrusions comprising (1) a first sub-array of said protrusions on the underside of said lid area and corresponding to said first sub-array of holes and (2) a second sub-array of said protrusions on the underside of said base area and corresponding to said second sub-array of holes, said disc being reclosably held on said top wall exclusively by said protrusions being received and retained in said holes, the circular array of holes and protrusions having a regular angular spacing, the disc protrusions being registrable for assembly with the top wall holes in any one of a number of angular positions equal to the number of holes in the periphery of the circular array.

2. A closure as in the preceding claim, the members of said first sub-array of protrusions being relatively easily releasably retained in said first sub-array of holes, the members of said second sub-array of protrusions being relatively fixedly retained in said second sub-array of holes.
