Plastic Paint Can

A method for making a mold for a plastic paint can having a bucket and lid, comprising the steps of:

• forming floor and wall cavities in a mold for a bucket, the wall cavity being in fluid communication with the floor cavity, the wall cavity having an inside axially extending steel surface and an outside axially extending steel surface for forming inside and outside mating surfaces of the bucket, respectively;
• forming central panel, closure and connector cavities in a mold for the lid, the connector cavity positioned between and in fluid communication with the closure and central panel cavities, the closure cavity having an inside axially extending steel surface and an outside axially extending steel surface for forming inside and outside sealing surfaces of the lid, respectively, which engage the inside and outside mating surfaces of the bucket, respectively;
• polishing all of the axially extending steel mating and sealing surfaces to a finish of either A3 or B1.

A plastic paint can, comprising:

• a bucket having a floor and at least one upstanding wall joined to the floor, the wall having inside and outside faces, the wall terminating at a rim which defines an open end of the bucket, the rim including a first mating surface on the inside face, and a second mating surface on the outside face;
• and
• a cover comprising a central panel, a closure member releasably engageable with the rim of the bucket, and a connector joining the closure member to the central panel, the closure member including an inside wall, an outside wall and a top wall joining the inside and outside walls, the inside wall having a first sealing surface engageable with the first mating surface of the rim and the outside wall having a second sealing surface engageable with the second mating surface of the rim, wherein all of said sealing and mating surfaces having a polished finish produced by corresponding mold cavity surfaces having polished steel surfaces.
