Abstract: A material for protecting the inside surface of a side seamed cylindrical container is disclosed. The material is of a thixotropic nature whereby edge protection is assured for a lap seam, a can seam or a welded seam, the latter being either a lap or butt-type joint. All of the foregoing constructions exhibit certain internal surface irregularities exposing raw metal to the interior of the container which must be appropriately covered in order to maintain sanitary protection of the contents ultimately packed within the container. Thixotropic materials have been found to provide the requisite surface adherence after application and until curing; thus, affording improved coverage of the various raw surfaces.

Abstract: A system and method for applying a meat release was to a formed container prior to filling, sealing and processing by application of the wax at elevated temperatures via a hot melt spray and post application of heat to the empty coated container to fuse the hot melt wax into a continuous internal coating to act as a release agent for subsequently added comestibles and the like.

Abstract: Tubular container bodies having a lap side seam, obtained by uniting a resin and an adhesive bondable therewith, are produced by applying the bonding resin to the limited lap area of body blanks moving in a continuous stream and applying heat to the limited lap area to cure the resin in less than one second; the resin may be so applied that the raw metal edge of the body blank is also coated. The resin may be subsequently reheated to the final state of cure in which it will bond to the tacky adhesive on the opposed lap margin of the body blank.
