  • Patent number: 9694933
    Abstract: A package for containing items having a flip-open package closure is provided. In some embodiments, the package includes a rigid package body and a flexible closure flap. The flexible closure flap is coupled to a hangtab portion of the package body such that the flexible closure flap moves from a closed position to an open position with respect to the package body based on a position of the hangtab portion. An upper edge of a front side of the package body engages the lower portion of the closure flap when the package is closed, while the lower edge of the closure flap is released from the upper edge upon pivoting backward of the hangtab portion. Such pivoting of the hangtab portion, and corresponding manipulation of the closure flap, may occur without directly contacting the closure flap.

  • Patent number: 9428286
    Abstract: Method of making a housing having wall panels (58, 60, 62 and 64) formed from a single, metallic work piece (50) by folding it at each of four locations defining corners all of which are spaced from opposite ends of the work piece (50) with at least one fold having an angle substantially different from a right angle and then securing together opposite ends (52, 54) of the work piece with a weld joint (56). As a result of bringing together the opposite ends, at least one of the panels curved in a stressed state and forms interior corner angles at opposite sides that are substantially different from a right angle. A closure base (48) is attached to the bottom of the wall assembly (44) to close and support the open bottom of the wall assembly (44), and as closure top (46) is attached an open top of the wall assembly (44).

    Abstract: A leak resistant food sleeve for holding single-serving food items is provided. The sleeve may be constructed from a blank that is folded into the sleeve when ready to use. The sleeve consists of two major and two minor sidewall panels, and first and second ends. The major and minor sidewall panels are folded to form a box-like structure. The first end consists of two major end flaps, two minor end flaps, and gusset panels extending between and foldably connected to one of the major end flaps and one of the minor end flaps. The gusset panels become layered between the minor end flaps and major end flaps when each is folded inward to close the first end, such that the minor end flaps, gusset panels, and major end flaps form a web of material that prevents fluidal and viscous substances from leaking out of the first end.

    Abstract: The present design is pizza box top that has a number of spatula-type trapezoidal shaped plates. These plates can be separated from the box and then used to lift out individual slices of pizza. The plates have a sharp point that cuts easily through the cheese in the center of the pizza. A pizza slice, resting on the plate can be picked up cleanly and safely, ready to eat. The number and size of the plates varies depending on the size of the pizza box i.e., small, medium or large. A second design uses a box insert that has the plates cut into it. This insert can then be placed into the lids of existing pizza boxes. In this way, the millions of pizza boxes already in inventory can be used without having to waste or modify them. The inserts, like the boxes are sized to fit into appropriate pizza boxes. A third design is used for supermarket pizzas that use a circular cardboard base. The standard base can be replaced with a circular base using the spatula-plates.

  • Patent number: 5364017
    Abstract: The invention relates to the creation of three dimensional objects from elements or blanks produced by inscribing inwardly and outwardly extending circles about a plurality of polygons, such as isoceles triangles, rectangles, or trapezoids of four, six or other even numbered sides through each point where the sides of the polygons intersect. To provide the appropriate arc lengths, the inscribed circles have the same diameter as the length of the side of the polygon where the arcs are to be inscribed. The element is bent or folded along each arc to form the three dimensional object. Multiple elements can be joined to form complex elements by superimposing individual elements upon a portion of adjacent elements. The objects thus formed can be held together by forces generated by the folded arcs, although an adhesive may optionally be used. The elements three dimensional objects, and methods of making same also form part of this invention.

After opening the wrapper the products may be consumed from either section. The wrapper is particularly suited for french fries or pizza pies.

  • Patent number: 5044550
    Abstract: A carton (11) with parallel flat front and rear surfaces joined by curved sides and a flip-top lid (10) hinged to the carton. The carton is composed of two superimposed layers adhesively secured at a joint line at lapped edges. The outer layer is slit along its front surface parallel to the carton ends and along upwardly extending curves around the sides to a fold line parallel to and raised above the front slit and the inner layer (12) has a cutout in its front surface above the front slit of the outer layer. The cutout curves upwardly short of the sides where tags (13) are cut out of the sides of the inner layer and the outer layer overlaps the inner layer at the carton ends. Top and bottom closures are adhesively secured to the outer layer at the ends of the carton.

  • Patent number: 4871080
    Abstract: The invention relates to the creation of three dimensional objects from elements or blanks produced by inscribing inwardly and outwardly extending circles about a plurality of polygons, such as isoceles triangles, rectangles, or trapezoids of four, six or other even numbered sides through each point where the sides of the polygons intersect. To provide the appropriate arc lengths, the inscribed circles have the same diameter as the length of the side of the polygon where the arcs are to be inscribed. The element is bent or folded along each arc to form the three dimensional object. Multiple elements can be jointed for form complex elements by superimposing individual elements upon a portion of adjacent elements. The objects thus formed can be held together by forces generated by the folded arcs, although an adhesive may optically be used. The elements, three dimensional objects, and methods of making same also form part of this invention.

  • Patent number: 4784273
    Abstract: A frangible, single-serving container for tortes and the like. The container comprises a base member for holding and serving the piece of torte or the like. The base member has a sector shaped base, a shallow base wall around the sector-shaped perimeter of the base, and a top rim on an upper edge of the base wall. The container also comprises a cover member for covering and protecting the piece of torte or the like. The cover member has a sector-shaped top, an arc-shaped back wall, two radial walls, and a bottom rim. The radial walls define a front edge, and the rim defines a bisected tab adjacent the front edge. The front edge is torn when the halves of the tab are forced in the opposite directions.
