Abstract: A display container comprises permanent side walls, a first end with at least two side wall flanges depending from the side walls and a second end sealable to form a closed bottom wall. At least a portion of one of the side wall flanges is permanently bonded to another side wall flange to form a closed, bonded top wall to maintain the display container in a permanently sealed condition so that product placed inside the container is inaccessible from either the top or bottom wall. A method of packaging incorporating the display container is also provided.

Abstract: A display container comprises permanent side walls, an end sealable along at least a portion thereof to form a closed bottom wall when the display container is in its set up position, and an open end having a pair of side wall flanges depending from opposing side walls. Each of the side wall flanges has a seal region with at least a portion of one of the seal regions being permanently bonded to the other seal region to form both a closed top wall and a bonded portion extending therefrom to maintain the display container in a permanently sealed condition so that the product placed inside the container is inaccessible from either the top or bottom wall. A method of packaging and incorporating the display container is also provided.

Abstract: A method for precision aligning of carton blanks having discrete fold lines in the manufacture of product display packages utilizes projecting alignment pins and transparent window blanks having laterally opposed notches. The alignment pins are arranged about the periphery of a carton blank having discrete fold lines and adjacent the inner edges of a formed opening for registration of the carton blank. The transparent window blank, having its pair of opposed notches in alignment with a fold line, is disposed in overlapping relationship over the opening of the carton blank, such that the alignment pins are received within the notches. The cooperation of the alignment pins and notches effectively provides precision alignment of the transparent window blank with the carton blank, for example, with respect to their fold lines and the like.

Abstract: An apparatus and method is described for precision aligning and joining of individual blanks together along an overlapping portion thereof by a bonding agent. The individual blanks are conveyed along the apparatus with their lateral edges retained in grooved guides for aligning and maintaining the blanks in precise registration with one another. The grooved guides are provided with ramped transition sections which displace the overlapping edge portion of the blanks towards each other such that the blanks can be joined together by a bonding agent provided therebetween upon further contact of the overlapping portion of the blanks.

Abstract: A file folder comprises a rear panel of stiff paper-stock and a front panel of transparent plastic material connected to the rear panel along a hinge line. Preferably, the hinge line is provided by a soft crease in the front panel which defines an inturned margin adhesively secured to the rear panel. The file folder is durable, is relatively inexpensive to manufacture and decorate, and affords notations to be made thereon using a variety of writing implements. Several different embodiments of the invention are disclosed.
