Abstract: A can assembly includes a can body, and a cap that is seamed to the can body, and a bag. The bag, which may be formed by a thermoforming process, includes a thickened portion as part of a peripheral flange that terminates in a bulb. A throat that receives the bulb is formed by necks on the body and cap such that the bulb is spaced apart from the seam. A constriction formed by the neck radially inboard from the bulb receives the thickened portion of the bag. The process for forming the can assembly includes forming the seam and thermoforming a billet into the bag. At least part of the flange is formed between matched portions of mold flanges.

Abstract: A container and associated cap assembly includes a container body having an open upper end defined by an annular rim, the rim having a substantially horizontal uppermost edge surface and a radially outwardly and downwardly extending bevelled surface. The cap has a top wall, a radially outer depending skirt portion and a radially inner depending skirt portion. The skirt portions are connected radially by an internal cap surface which includes a first substantially horizontal surface portion extending radially away from the radially inner skirt; a second downwardly and outwardly inclined sealing surface portion, and a third radiused surface portion connected to the radially outer skirt. The second downwardly and outwardly inclined sealing surface is sealingly engageable with the bevelled surface of the annular rim such that the substantially horizontal uppermost edge surface is axially spaced from the cap top wall upon full threaded engagement between said cap and said container body.
