Abstract: A system for opening encased articles has a cutting apparatus that includes a channel formed from spaced-apart parallel walls. A cutting member having a cutting edge extends from one wall into the channel. A protrusion disposed in the channel at least partially overlaps and at least partially obstructs the cutting member. The channel is adapted for receiving the flanged edge of the article and the protrusion is displaceable to expose the cutting edge of the cutting member. A system further has the cutting apparatus juxtaposed with a container for storing at least one encased article.

Abstract: A lockable container includes a sleeve, a locking assembly, and a slideable platform. The slideable platform can be stored in the sleeve. The locking assembly and the slideable platform can each have one or more of an engaging mechanism and a receiving mechanism, with reciprocal engaging mechanisms and/or receiving mechanisms being included at the other element. A release button can be included in the locking assembly to disengage the engaging mechanism from the receiving mechanism.

Abstract: A unit dose package formed from the combination of a flexible portion, preferably of paperboard, which houses unit dose materials, and a rigid molded plastic locking mechanism comprising a child resistant trigger release mechanism.

Abstract: A multi-use envelope for at least two mailings comprises opposed front and rear panels foldably connected together at their bottom edges and secured together at their side edges by side closure flaps to form an envelope structure. The improvement comprises a pair of closure flaps foldably attached respectively to the top edges of each of the front and rear panels wherein each closure flap has an independent means for sealing and opening the envelope. A first closure flap is folded inside the envelope for the first mailing while the other closure flap is used to close the envelope. Upon receipt, the first closure flap is folded outside the envelope for use in closing the envelope for the second mailing.

Abstract: A CD holder is prepared from three separate components comprising, an outer folder component, an intermediate panel, and an inner storage compartment. The storage compartment is die cut to provide a substantially circular opening having at least two spaced contact points and an integral spring element spaced around the periphery of the opening. CD's of varying diameter are captured by and retained in the storage compartment through the complementary action of the two or more contact points and the spring element.

Abstract: A package comprising a flanged tray and a wrapper for covering the tray includes an easy opening feature for providing access to the contents of the tray. The wrapper is formed from a substantially rectangular blank of paperboard which is cut and scored to provide a top panel which is adhered to the tray flange, at least one side wall foldably attached to the top panel which lies adjacent to a tray side wall and a bottom flap foldably attached to the side wall which is adhered to the bottom of the tray. The easy opening feature includes a tab element formed from a part of the side panel which is connected to a removable lid portion of the top panel. The tab element and removable lid portion are formed by spaced apart, partial depth cut lines located on the inner and outer surfaces of the top panel and the side panel.

Abstract: This invention relates to a hexagonal paperboard carton that is tapered with an automatic bottom. Such structures of this type, generally, provide a peeling feature that allows the consumer to remove the carton from the product in a continual, spiral strip.

Abstract: A tearstrip opening for the closure flap of a paperboard container is formed by a single line of tear and an adjacent delamination area located within the closure flap. The tearstrip is applied to one or more of the closure flaps of the container as required. The tearstrip is removed by the combined action of separation of the paperboard along perforations which define the single line of tear and ply separation of the paperboard adjacent to a partial depth cut line of weakness spaced from the single line of tear. When removed, the tear strip releases the closure flap from a side wall of the container while leaving a portion of the closure flap still attached to the side wall.

Abstract: A composite food packaging article having internal partitioning walls and corresponding method of manufacture is constructed from flat, machine formed paperboard. A pair of die cut and folded paperboard blanks are inserted within the opposing cavities of a blow mold. A hot-flow parison between the cavities expands to structurally unitize the folded paper blank into a fluid impermeable tray vessel.

Abstract: A bottle type container is fabricated by blow molding a continuous wall liner of thermoplastic polymer integrally to the interior wall surface of an oppositely matched pair of paperboard cladding jackets. Paperboard cladding jackets respective to each pair are joined substantially edge-to-edge along the meeting seam exclusively by the continuous liner wall lap. For container stability when resting on a flat surface, at least one folded ridge is formed in the bottom edge panel of both jackets.

Abstract: A paperboard lid for a tray type ovenable carton is provided with weakened score lines only in its lower surface to form an easy opening means. The lid includes a first continuous score line extending around the periphery of the lid and a second weakened score line of abbreviated length at one corner of the lid spaced from, but adjacent to, the first continuous score line. The lid preferably includes a right angle corner where the second weakened score line is located to provide a lift tab for venting the carton and for removing the lid to open the carton.

Abstract: A container for packaging, storing and heating food is prepared from a single blank of paperboard that is coated on at least one side with a thermally stable heat-sealable coating. The container is substantially rectangular in shape and includes upstanding side, front and rear walls connected to a bottom panel, gusset panels at each corner, integral flanges connected to the side walls, an integral lid foldably attached to the rear wall and adapted to be heat-sealed to the side wall flanges, and a front closure flap integral with the lid and adapted to overlap and be sealed to the front wall.

Abstract: A porous anodic aluminum oxide membrane, at least one surface of which is profiled on a scale of 0.01 to 50 mm, may be made by profiling a surface of an aluminium metal substrate anodizing the substrate to form a porous membrane on the surface and separating the membrane from the substrate. The profiling may consist of a system of parallel ribs and troughs. Structure having an interesting properties as filters can be built up by the use of several such membranes bonded to one another along the crests of the ribs.

Abstract: The invention provides porous anodic aluminium oxide film having a major face with an area of at least 50 cm.sup.2, the film material containing phosphorus derived from the anodizing electrolyte, preferably at least 5 microns thick and preferably having pores spaced 0.1-0.5 microns apart. The film may be made by anodizing one or more aluminium metal anodes of suitable area in an electrolyte based on phosphoric acid at a concentration of 5-150 g/l maintained at a temperature in the range 5.degree.-50.degree. C. using an anodizing voltage of 40-200 V. After separation from the metal substrate, the films have intersecting properties for use in filters.

Abstract: A microwave ovenable package is disclosed including a top structure which incorporates therein a pair of handle elements useful for removing the package from the microwave oven. In the preferred embodiment, the top structure includes integral side walls which are adhered to the sides of the package. The integral side walls are connected to the top structure along cut/scored lines which delaminate upon opening the top. The portions of the side walls which remain attached to the package can then be folded outwardly to produce handles for removing the package from the microwave oven.

Abstract: An auto lock tray is formed from a single blank of cut and scored foldable material comprising a bottom panel, side and end walls extending in an upright condition at each edge of the bottom panel and diagonally disposed product supporting panels interiorly of the tray which extend from the upper edges of the side walls downwardly at acute angles with the bottom of the tray. The product supporting panels are retained in position within the tray by a pair of locking flaps including interengaged tabs and slots which become fully engaged as a result of an over center folding action.
