System and method for repurposing a tennis ball canister

Abstract

A system and method for repurposing tennis ball canisters, wherein said system comprises an insertable liner, further comprising a vessel, a lower collar flange, an upper collar flange, a plurality of notch(es) distributed about the upper collar flange, and a collar. Said system further comprises a retainer ring comprising a band portion, one or more tab(s), and a radially inward protruding ridge within said band. Said method comprises placing at least the liner into the bore of the canister barrel until the underside surface of the lower collar flange is in contact with the canister's lip, placing the retainer ring on the topside surface of the upper collar flange, orienting the retainer ring's angular position until the tab(s) are within the complementary notch(es) of the upper collar flange, and finally pressing the retainer ring downward until the retainer ring's radially inward protruding locking topology is snapped under the canister's lip.

Dependencies are inferred from the claim text.
