Abstract: The disclosure relates to a method of preparing a web of flexible material for production of receptacles for packaging. The method comprises the steps of feeding a web of flexible material past a succession of stations in which operations are carried out on the web including defining blanks for receptacles having walls and tabs by creating fold lines in the web, and then laminating a film of heat-sealable plastics materials to a face of the web of the flexible material. The film of heat-sealable plastics provides a heat-sealable surface on the web for bonding tabs of each blank together to form seams between adjacent walls whereby the blanks, when severed from the web, can be erected to form receptacles having openings to receive items to be packaged.

Abstract: The present invention is a container for use in baking and shipping food items. The container is formed of a paperboard material and includes a heat-resistant coating applied to all of the interior surfaces of the container. The coating enables a number of food items to be positioned within the container in contact with the coating such that the container and food items can be baked to properly prepare the food items therein. After baking, the container and food items can then be wrapped or otherwise packaged for shipment without transferring the food items to a separate shipping container. The container also includes a pair of end walls that are movable with respect to the container between retaining and dispensing positions to enable the container to be configured as serving tray for the items contained therein.

Abstract: Stiffened double walled gift boxes are formed from paperboard blanks having main panels and wall panels with inner halves connected by gussets. A stiffener with a central panel and hinged sides half as wide as the side panels is placed in the main panel. Adhesive is applied on inner surfaces of the outer panels. As the wall panels are folded along peripheral edges of the main panel the loose stiffener is aligned by the wall panels. Sides of the stiffener bend with side panels of the box. Gussets are folded and placed inside end walls and are secured by outer end panels secured to inner end panels. Outer side panels are folded inward and adhered on sides of the stiffener, locking the stiffener in place.

Abstract: A corrugated plastic box is disclosed. The box is provided with an L-shaped or chair-shaped end panel which can be adhesively secured to a box side panel. The end panel has a lower portion which extends over a relatively great number of box side corrugations, and an upper panel portion which extends over fewer box side corrugations, so as to spread interior box loads across a number of corrugations and inhibit box side bowing. The box sides are also strengthened by providing upper panels which are rolled over along the top edges of the box, the panels are then food or otherwise fastened to the side panels. The rolled-over top edges thus formed strengthen the box, and prevent the entry of contaminants into the otherwise-exposed side panel corrugation flutes. The box is provided with a number of specially shaped box bottom panels which enable the box to be quickly and easily erected by even inexperienced personnel.

Abstract: Blanks for forming open sided containers and mating covers from carton stock material include strips of non-stick material secured to the blank by means of a strippable adhesive. The adhesive adheres to the carton stock material with a substantially higher adherence force than the adherence force between the adhesive and the non-stick material, so that the non-stick material can be removed, readily, to expose the tacky surface of the adhesive. The carton blanks are marked with a predetermined pattern of fold or crease lines which allows the blank to be bent and folded into the shape of a container or a container cover. The non-stick material facilitates handling and separation of individual blanks that have been shipped and stored in tightly packed, stacked arrays, while the exposed adhesive surface engages specifically formed tabs and/or flaps of the blank in overlapping, abutting relationships to secure the blank in its final, assembled, container/cover shape.

Abstract: A corrugated board tray has stacking lugs extending from double thickness side walls. The stacking lug is formed from an integral upward extension of only the outer one of the side wall panels. The lug is folded inwardly and secured to the inside of the side wall. Corresponding slots are formed at the junction of the side wall and the base to receive the stacking lugs of a lower tray. Half-size trays may include stacking lugs and slots formed in the end walls.

Abstract: The container made of cardboard or similar material intended to the packaging of objects is formed from a blank which is comprised at least one flat rough form and which presents, when in flat condition, different components: a polygonal planar base intended to receive the objects to be packaged and walls adjacent to the base and intended to be straightened up with respect to said base in order to set the container in volume, a so-called "closure " panel being optionnally provided in order to close the container once the objects to be packaged have been placed on the base.

Abstract: A container blank has a bottom panel with outwardly extending inner and outer end panels which fold up to form double thickness end walls. Two opposed parallel side panels have glue tabs which are affixed to the outer end panels. Each glue tab has a 45-degree angle fold line which allows the side panels to be folded to overlie the bottom panel during shipping. In a covered box where the height of the box h measured vertically exceeds one quarter the length of the end panel and approaches one half the length of the end panels, there is not space available to receive the cover front flap tab within a pocket defined between the end wall and an adhesively attached glue tab, if the glue tabs in front and in back are of equal size. To accommodate the enlarged cover front flap tabs, the front glue tabs may extend a greater distance along the end panels than the rear glue tabs. The rear glue tabs are less than half the length of the outer end panels, and do not extend frontwardly beyond the glue tab fold line.

Abstract: A container is readily set up by hand from a glued-up blank. The blank has a bottom panel with outwardly extending inner and outer end panels which fold up to form double thickness end walls. Two opposed parallel side panels have glue tabs which are affixed to the outer end panels. Each glue tab has a 45-degree angle fold line which allows the side panels to be folded to overlie the bottom panel during shipping. By pivoting the outer end panels to be perpendicular to the bottom panel, the side panels are brought upright by the attached glue tabs, and the inner end panels are thus positioned to be engaged over the glue tabs. The glue tabs may extend to permit rectangular adhesive attachment regions. The structure may be incorporated within a double-walled shadow box, a tray or lid, a covered box, or other container structures.

The flaps have an upper wall portion covering the openings and a lower wall portion attached to the sidewall. The upper wall portion is spaced from the sidewall to form a hollow space behind the openings. The lid has a top member and a peripheral flange with projections formed therein to fit into the container sidewall openings and lock the lid onto the container.

Abstract: A box is formed of a blank of sheet material wherein a filler is sandwiched between an inner liner and an outer liner. A pair of V-grooves is formed parallel to each edge and another V-groove is formed parallel to the pair of grooves on the side away from the edge. The V-grooves of the pair of V-grooves have center lines spaced apart a distance of substantially two thicknesses of the sheet material. The blank is folded upwards at the single V-groove, and then is folded back at the pair of V-grooves to produce successive 90-degree folds. The outer liner extends continuously over the outer side, top edge, and inner side of the resulting double-thickness wall. A similar technique can produce a box with multiple-thickness walls.

Abstract: A shipping container formed by wrapping a slotted flexible sheet about rigid end panels having upper corner projections that extend through the slots. The side panels of the container are of multi-ply construction, with retaining tabs foldably connected to the inner plies. The retaining tabs are for the purpose of contacting the lower portion of smaller containers packaged within the shipping container and preventing the smaller containers from shifting toward the side panels during shipment and handling.
