Abstract: An identifier such as a strip of heat resistant metal, containing preselected identifying information in the form of an alpha-numeric serial number is concealingly retained in a carrier member. The carrier member has a preselected shape and configuration adapted for releasable engagement to a structure, such as an item of personal property, to be identified by information such as the alpha-numeric serial number to disclose in a concealed manner ownership of the structure. In one manner of use, the carrier is an integral part of the structure to prevent visual detection of the carrier on the structure by a thief. The carrier member includes in one embodiment an amorphous body with the metal strip identifier encapsulated within the amorphous body. The amorphous body is indistinguishably attached to an item of personal property or the like, which ownership is identified by the information inscribed on the metal strip and is concealed on the item.

Inner and outer caps are threaded onto the respective inner and outer necks, and each cap is provided with an elastomeric liner. The inner cap is further provided with an axial bore to allow a hollow needle to pass therethrough, thereby enabling material within the container to be withdrawn through the needle, and the inner elastomeric seal reseals itself after withdrawal of the needle.

Abstract: This application is concerned with food packages made from sheet or film into the forms of heat sealable pouches, bags, or covered trays in which the food product is placed, the package sealed, and the packaged food processed in a pressure cooker or retort to permit the packaged food to be stored without refrigeration. Certain food products can be rendered commercially sterile by hot filling the package at temperatures below boiling to permit storage for long periods without refrigeration. While still in the sealed package of the present invention, the consumer can heat or cook the food by immersion in boiling water or by microwave oven. The sheet or film is a multilayer construction wherein each layer performs specific functions and the choice of materials for the layers is interdependent to provide a film structure having all desired properties at the least cost.

Abstract: A lightweight container having a readily removable corrugated sidewall. The inner ply of the sidewall is a corrugated sheet having a selected length and width. A bottom wall member is positioned adjacent the lower axial edge of the inner sheet. A flat outer sheet, of selected length and a width greater than the width of the corrugated inner sheet, is joined to the inner sheet to define the outer ply of the sidewall. The outer sheet projects beyond the lower edge of the inner sheet and is folded against and secured to the bottom wall member, to thereby restrain movement of the bottom wall member. A frangible joint is defined along which the sidewall can be severed from the bottom wall without severing the corrugated inner wall, so that the inner wall adds rigidity without interfering with the ready removal of the sidewall. In the preferred arrangement, the adjacent ends of the inner sheet are in a substantially abutting and unsealed relationship to assist in the opening of the container.

Abstract: This relates to the encasing of shirred casing strands for the purpose of maintaining the shape thereof during soaking and subsequent to the soaking until such casing strands are applied to a stuffing horn. Each casing strand is encased in an overwrap casing which is applied in tubular form and preferably is in the form of netting. The overwrap casing is shaped at least at one end of the casing strand to define closure panels by twisting the overwrap casing at that end of the associated casing strand so as to reduce the diameter of the overwrap casing and to facilitate the reverse folding of the overwrap casing. The opposite end of the overwrap casing may be closed in a similar manner or by a simple gathering of the material of the overwrap casing and the application of a conventional clip. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: Individual flanged trays are deposited on a conveyor belt. A continuous film is applied across the top surface of the trays. A heated flat plate is pressed into the film and causes the tray flanges to bend to a desired position. The plate heats the film throughout and bonds the film to the tray flanges. Directly thereafter and while at the same station, vacuum is applied which serves to deform the film into the interior of the trays. The formed film preferably has rounded corners and may be partially separated from the bottom wall and side walls of the tray by an air space. Thereafter, a heated plug preferably having insulated sides, heat seals the now deformed film to the bottom wall of the tray. A cutting device trims the excess film at the tray flanges. The excess film may be scavenged and recycled. The cutting device may be provided at the deforming station or the sealing station or at a trimming station downstream of either of these stations.

Abstract: There is disclosed a container for containing a liquid such as paint, the container having a side wall and a bottom moulded in one piece from plastics material, the container being formed to co-operate with and retain a removable lid, and comprising a flexible inwardly projecting flange moulded integrally with the side wall and adjacent the top thereof, the flange being upwardly and inwardly inclined at its attachment to the side wall. Because the flange is flexible and is inclined to the side wall at its point of attachment to the side wall, the core on which the container is moulded can be withdrawn from the container past the flange, as the flange will deflect and ride over the core. The flange then springs back to its inwardly projecting position and serves to prevent liquid slopping out of the container if the container is filled with liquid on a standard filling line such as is used for metal lever-ring paint containers.
