A reclosable container assembly is disclosed comprising a container body having an open end and a cover for closing the open end. The cover has a wall portion extending into the open end of the container body and interengaging therewith to provide a snap-fit therebetween. The cover has a peripheral flange including a portion extending radially outwardly across the open end of the container body and terminating in a peripheral skirt. The underside of the radially extending flange portion is provided with a peripherally continuous V-shaped recess providing a line of weakness along which the material of the cover fractures and tears in response to an attempt to displace the cover flange in the direction to separate the cover from the container body. The material along the line of weakness fractures in response to a displacement force less than that required to disengage the snap-fit between the container body and cover, and provides a visual indication that the container assembly has been tampered with.
Laminated Tube For Collapsible Containers And Method Of Making Same
A laminated tube adapted to be used as the body of a collapsible dispensing container includes an inner layer of an epoxy resin, an intermediate layer of aluminum foil and an outer layer of thermoplastic material. The tube is made by forming a foil and epoxy resin laminate into tubular form having longitudinally extending circumferentially overlapped edges, and extruding thermoplastic material about the foil.
