Abstract: A multiple pocket, expandable envelope is formed by folding panels of a planar, unitary blank relative to each other. The envelope has two pair of front and back panels hingedly coupled along a common end edge. Each front and back panel includes a front and back divider panel therebetween to define six pockets within the envelope. Each front panel is hingedly coupled to a front divider panel along a fold line at one side thereof. Each back panel is hingedly coupled to a back divider panel along a fold line at one side thereof. A plurality of side panels hingedly couple each front panel to a front divider panel at the other side of the front panel, each back panel to a back divider panel at the other side of the back panel, and the front and back divider panels at each pair to each other. One of the front panels in each pair is hingedly coupled to one of the back panels in an adjacent pair to form the six-pocket, expandable envelope.

Abstract: An all plastic carton housing a fluid is provided with integral, kidney-shaped depressions in adjacent side walls of the carton to serve as handle members to aid in pouring the fluid contents from the carton. The carton also includes an integral pouring spout having a center line axis lying in a diagonal plane between the side walls of the carton provided with the handle-forming depressions to complement the handles in enabling accurate pouring of the fluid contents of the carton while grasping and tilting the carton. The spout is also formed so as to lie flat on top of the carton when closed thereby facilitating compact shipment and storage and display where shelf space is at a premium.

Abstract: A container preferably supporting a sealed beam headlight in which a pair of opposite flaps at each end are each provided with a short flap extending partially across each of the original flaps and secured thereto. The short adhesive flaps in turn have a longer flap attached thereto wherein the sum of the lengths of the longer flap and the short adhesive flap is greater than that of the first flap so that when the first flap is folded into closed position, the additional flap connected to the adhesive flap necessarily moves down into a diagonal relationship between the closing flap and the inside of the side wall. This structure is repeated on both sides at both ends. The diagonal flaps cushion the headlight. Each of the diagonal flaps in turn has a further flap which in the closed condition of the container extends along the inside of the side wall.

Abstract: A sleeve slides over an erected and closed carton to maintain it in its closed position. The sleeve may be of paper or paperboard and includes an integral flap covering an underlying sleeve area. The flap and underlying area are preferably printed or decorated to form a greeting or gift card.

Abstract: In a multi-layer sheet material from which containers adapted to heat food in microwave ovens may be erected, the sheet material comprising a core layer and a transparent surface layer on each side of the core layer, the improvement comprising an intermediate layer located between the core and at least one of the adjacent surface layers, the intermediate layer being a relatively thin layer of polyethylene terephthalate and a design printed on one side of the intermediate layer whereby the design is visible through the adjacent surface layer and is prevented by the adjacent surface layer from being physically contacted.

Abstract: A carton having a plurality of sidewalls forming a rectangular tube includes a transversely extending platform therewithin spaced from one end of the carton. The platform is hingedly joined along one lower edge of a sidewall by a triangularly shaped connecting tab specially cut to allow pivoting of the platform 180.degree. relative to the sidewall to which it is joined. Printing is applied to only one side of the one piece blank from which the carton is formed, and the platform is pivoted during folding of the blank to dispose the printed side of the platform facing upwardly to be viewed through a display opening in one of the sidewalls.

Abstract: A carton with a plurality of cells and a handle and a blank for forming same have a collapsible arrangement for automatically forming a bottom, partitions and a handle. This arrangement includes bottom panels hingedly coupled to the bottom edges of the wall panels, divider panels separated into first and second sections hingedly coupled to two of the bottom panels at edges thereof remote from the wall panels, and a handle structure coupled to the divider panels at edges thereof remote from the bottom panels. This permits the carton to be shipped and stored in an essentially flat, collapsed configuration and then easily arranged to its assembled, expanded configuration by the application of inwardly directed forces against the side edges of the collapsed carton. These forces cause the bottom panels, divider panels and handle structure to move automatically with the movement of the side wall panels of the carton.

Abstract: Hydroxyl-containing filler reinforced thermoplastic polymers, such as polyolefins, are disclosed having improved physical properties such as impact strength, break strength and flexural modulus. The filler is compatibilized with a thermoplastic polymer containing labile atoms by mixing the two together in the presence of a coupling agent, such as maleic anhydride and a free radical initiator such as a peroxide catalyst. In a preferred embodiment, clay is coated with polyethylene by mixing the two in the presence of a peroxide catalyst and maleic anhydride and the coated filler is then compounded with additional polyethylene. In another preferred embodiment, a filler is coated with a polyolefin having a high melt index and the coated filler is then compounded with a polyolefin having a lower melt index. Also disclosed are various means for molding the compatibilized composites of this invention.

Abstract: A paperboard carton and blank therefor having a reclosable spout. The spout includes a main spout member and a secondary spout member. The main spout member is defined by a fold line, first and second tear-away members extending from the fold line and a third tear-away member interconnecting the first and second tear-away members. The secondary spout member is defined by a second fold line and the third tear-away member. Each tear-away member is formed from two cut lines, one on the exterior surface of the paperboard and the other on the interior surface, neither penetrating the full thickness of the paperboard. After the tear-away members are torn-away, the secondary spout member is overlapped onto the exterior of the main spout member to reclose the spout.

Abstract: A flexible paper bag suited for containing granular products includes an improved valve in a corner of one end thereof which is adapted to receive a filler spout of a product dispensing machine therein. The valve comprises a tubular plastic sleeve interposed in an opening between opposing, hinged bottom flaps of the bag. The bottom flaps shift about their hinges toward each other under weight of product within the bag to collapse the sides of the sleeve valve, thereby closing the latter. One extremity of the sleeve valve, which extends into and is freely suspended within the bag, acts as a self sealing valve while the bag is being filled. Shifting of the product within the bag after filling thereof folds the sleeve over onto itself, thereby positively closing the sleeve valve.

Abstract: A display carton for a replacement wheel assembly of the type used on a lawn mower, wheelbarrow, spreader, or other garden-type vehicle. The carton is provided with opposed sidewall panels which contain cutouts so that the wheel assembly protrudes beyond the carton sides enabling a purchaser to view the wheel tire prior to selecting the wheel assembly for purchase. Each sidewall panel has a tuck end panel inserted into the carton and secured in place by a tuck lock flap pivotably connected to the rear wall panel of the carton. The tuck lock flap includes a plurality of creases intermediate its edges so that it can be folded and positioned between the wheel assembly and a tuck end panel within the carton adjacent to the rear wall panel of the carton, between the rear wall panel and the wheel assembly, to preclude opening of the carton and removal of the wheel assembly on display.

Abstract: Tearing, blistering, delamination and other defects in deep drawn plastic laminated paperboard containers are eliminated by adding controlled amounts of warmed moisture to the paperboard immediately prior to forming thereof. Water is heated to a desired temperature and is applied by in-line processing equipment to the unlaminated side of the paperboard which functions to both soften and paperboard and preheat the laminate. By heating both the male and female parts of a die press employed for forming the preheated, softened laminate into the container, preheating the laminate using warm water prior to forming and, continuously controlling the moisture added to the paperboard, the degree of stress imposed on the plastic layer of the laminate and the resulting defects in the formed container are significantly reduced.

Abstract: Disclosed is a carton especially adapted to package single servings of pie. The carton has a triangular shape due to triangular top and bottom panels. A trapezoidal end wall connects the top and bottom panels at the bases of the respective triangles and slants outwardly from bottom to top. The bottom panel has inner side wall panels attached to it. The inner side wall panels are secured in the vertical upright position by means of corner flaps which are preferably secured to the outer surfaces of the inner side wall panels. The top panel can contain an opening which is preferably covered by a strip of film. The fragile pie crust is better protected by the slanted end wall, and further by the overlapping corner flaps.
