Claims11
A container holding a supply of plastic tubular stock for the incremental withdrawal of portions thereof, said plastic tubular stock comprising a high-density polyethylene film having a malodor counteractant comprising an aromatic unsaturated carboxylic ester wherein the unsaturation is conjugated to both the aromatic ring and the carbonyl group portion of the carboxylic ester.
A cassette for use in dispensing flexible tubing packed therein in layered form, the cassette comprising a rigid body formed by a central tubular core open at top and bottom, a surrounding casing wall positioned to provide a space between said tubular core and said casing wall and a base wall joining a lower end of said surrounding casing wall to the lower end of said tubular core, a length of flexible tubing packed profusely in a tightly layered mass in said space to constitute a pack surrounding said tubular core, and a cap placed over a portion of said pack, said cassette comprising a malodor counteractant incorporated into a high-density polyethylene film of the flexible tubing wherein the malodor counteractant is an aromatic unsaturated carboxylic ester and wherein the unsaturation is conjugated to both the aromatic ring and the carbonyl group portion of the carboxylic ester.
