Patent number: 5894268Abstract: This anti-theft device applies a security strip directly onto the frame of an audio or video cassette. The location of the strip could be anywhere on the shell or frame. For example, one could locate it next to the UPC code on the underside of the shell, on the spine, or anywhere under the label or paperboard sheath. While the hidden strip is useful with a standard cassette and label, it is especially useful with a composite cassette having a paperboard sheath. The hidden security strip makes detection and removal virtually impossible.Type: GrantFiled: January 28, 1998Date of Patent: April 13, 1999Inventor: Edwin C. McLaren

Patent number: 4407426Abstract: A closure for a cylindrically shaped ice cream carton or the like includes a unitary circular shaped plastic lid provided with a depending skirt portion. The top surface of the lid includes an upwardly and inwardly extending concentric bead inwardly tapered on its outer surface to enhance retaining a plurality of similar lids in stacked relation. The bead rigidifies the lid, enhances nested stacking of lid-carton assemblies and provides a locking and protective recess for labels containing printed indicia. The skirt of the lid includes a lower outwardly tapered inner surface portion for mating with the outer surface of the bead to enhance nested stacking of the lids and to enable the lid to be grasped and readily removed from tight fitting engagement with an ice cream carton. An upper, inner annular recessed portion of the lid skirt accommodates expansion of the ice cream carton without the lid popping off the carton.Type: GrantFiled: April 13, 1981Date of Patent: October 4, 1983Assignee: Champion International CorporationInventors: Edwin C. McLaren, David J. Adamek

Patent number: 4389802Abstract: A lid insert is provided for releasable connection to a plastic lid having a subtantially flat top surface and an upwardly and inwardly projecting peripheral bead disposed above and spaced from the top surface of the lid. The lid insert is made of paperboard material having a planar configuration generally corresponding to the configuration of the flat top surface of the lid. The periphery of the planar lid insert includes a plurality of alternating indents and nodes. The area defined by the outermost points of the insert is greater than the area defined by the upwardly and inwardly projecting bead. This peripheral configuration of alternating nodes and indents facilitates the initial placement of the insert on the lid and enables the insert to compensate for the different expansion characteristics of the lid and the lid insert.Type: GrantFiled: November 12, 1981Date of Patent: June 28, 1983Assignee: Champion International CorporationInventors: Edwin C. McLaren, David J. Adamek

Patent number: 4344814Abstract: A multi-piece, tub shaped paperboard container having a circular opening in the top thereof is provided with a multi-piece, reinforced rim coated with a layer of meltable plastic and is assembled by appying heat to overlapping seams in order to melt the plastic coating and thereby seal the seams. Heat is applied evenly around the entire periphery of the rim by a 2-piece, annularly shaped, heated collar which may be selectively shifted into conforming engagement with the container. The even application of heat around the entire periphery of the rim equalizes the surface tension of the plastic coating during melting thereof to avoid deformation of the rim during the heat sealing process.Type: GrantFiled: September 22, 1981Date of Patent: August 17, 1982Assignee: Champion International CorporationInventor: Edwin C. McLaren

Patent number: 4305524Abstract: A closure for a cylindrically shaped ice cream carton or the like includes a unitary circular shaped plastic lid provided with a depending skirt portion. The top surface of the lid includes an inverted V-shaped bead extending concentric with and inwardly spaced from the outer circumference of the lid to provide a bead for retaining a plurality of similar lids in stacked relation, precluding them from slipping inwardly relative to each other. The top surface of the lid also includes a depressed centrally located area, which rigidifies the lid and provides a recess for labels containing printed indicia. The skirt of the lid includes a bottom, outwardly flared portion enabling the lid to be grasped and readily removed from tight fitting engagement with an ice cream carton and an upper, recessed portion to accommodate expansion of the ice cream carton without the lid popping off the carton.Type: GrantFiled: April 4, 1980Date of Patent: December 15, 1981Assignee: Champion International CorporationInventors: Edwin C.
