ABSTRACT:
An improved coin operated vacuum cleaner canister with coin mechanism is disclosed. A blank having a polygonal or rectangular opening is rolled into a canister sidewall. A frame comprising a plurality of straps defining a polygon with an open side is mounted within the opening in the sidewall with the frame depending from the opening into the interior of the canister. A coid mechanism enclosure is detachably mounted to said frame such that a coin mechanism and coin container are receivable within the enclosure. The enclosure includes a flange which surrounds the opening of the enclosure and overlies the sidewall surrounding the opening in the sidewall. The flange is curved generally codiametrically to the sidewall. An alternative embodiment provides a coin duct disposed within the canister for passage of coins handled by the coin mechanism from the coin mechanism into a vault mounted in the base on which the vacuum cleaner is mounted.
