  • Patent number: 5855543
    Abstract: A kit for making boxes from paper card stock. The kit has a flat plate with a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top.

  • Patent number: 5487716
    Abstract: A wrap film containing box in which a projected portion of a thin sheet out of a serrated member serves as a tab and in which a thin sheet body on the back of the serrated member plays the role of reducing the fastening strength. Therefore, the serrated member can be removed easily and safely without reducing the rigidity of a cardboard portion of the box body where the serrated member is mounted (i.e., without impairing the cutting performance of the serrated member).

  • Patent number: 5306224
    Abstract: A paperboard shaped into a profile substantially the same as that of a carton blank for folding into a carbon is formed with a plurality of first slits on an edge of the paperboard at a predetermined angle relative to the edge and with a plurality of second slits on the same edge at a predetermined angle relative to the first slits in such a manner that saw-teeth are integrally formed thereon. The saw teeth are immersed in a bath of a quick drying adhesive including .alpha.-cyanoacrylate to be impregnated with the adhesive and then dried, thereby forming teeth constituting a cutter on the carton blank. The carton obtained by folding the carton blank can be used as a packaging container for accommodating a roll of wrapping wed.

  • Patent number: 5286247
    Abstract: An apparatus and method for forming a sheet of material into a flower pot or flower pot cover with fins. The apparatus comprises a male mold, a female mold having an opening mating with the male mold, and means for moving the male mold into and out of the opening of the female mold with the sheet of material between the two molds. To form outwardly extending fins in the flower pot cover, fingers are extended from the male mold to push folds in the sheet of material between segments of the female mold. The female segments are closed on the folds to form fins in the sheet of material as the male mold is pressed into the female mold to make the flower pot cover. To form inwardly extending fins, fingers are moved between the female segments to push folds in the sheet of material between segments of the male mold. The segments of the male mold close on the folds to form fins in the sheet of the material as the male mold is pressed into the female mold to make the flower pot cover.

  • Patent number: 4754541
    Abstract: An apparatus for joining and folding container sections to form a hinged container. Two container sections are transported in end-to-end relation on a conveyor and the downstream section is engaged with a stop while a pusher member is pivoted into engagement with the trailing edge of the upstream section to force the sections together and engage snap fitted hinge elements on the two sections. The hinged container is then discharged from the first conveyor onto a second conveyor located at a level beneath the first conveyor and operating at a slower speed than the first conveyor. As the leading section of the hinged container falls from the upper conveyor onto the lower conveyor the increased speed of the upper conveyor will fold the trailing section over the leading section to provide a closed hinged container. The closed container then passes under a spring loaded pressure member which ensures that locking elements on the two container sections are fully engaged.

  • Patent number: 4659322
    Abstract: A unique resealable container is described together with a method for converting a standard container of the type commonly used for packaging milk or other liquids into said container. An apparatus for carrying out this method is also described. The resealable container consists of a rectangular box having four flaps and a closing band for sealing the box. The closing band holds the flaps in their closed position. The container may be produced by making six cuts in a standard container of the type normally used to package milk or the like. The cuts are made with the apparatus of the present invention using an ordinary kitchen knife. The apparatus of the present invention supports the container during the cutting process and guides the knife to assure that the cuts are made in the correct locations.

  • Patent number: 4641750
    Abstract: A two-ply, book-style album (10) comprises an inside tray sheet (12) and an outside cover sheet (14). Sheets (12 and 14) are preferably formed of high-density polyethylene, and are thermally heat-sealed together by means of a peripheral seal (34) and spine rules (36). The spine rules (36) include longitudinal grooves (38) formed to a substantial depth into the front surface of the inside tray sheet (12) in order to define living hinges which provide a roundish, less square spine of more pleasing appearance.

  • Patent number: 4491267
    Abstract: The invention provides a process for making a dry powder box with greater geometrical stability and free of pin holes, gaps and the like through which powder may sift. The process uses a carton blank having a bottom closure wherein a pair of relatively large, opposing dust flaps are first folded into the carton tube, in order to define, maintain and stabilize the cross section of the carton. Then, a pair of relatively smaller, opposing major flaps are folded and glued over the open sides of the large dust flaps. This combination of flaps keeps the large flaps from working out of alignment and helps maintain the cross sectional stability of the box. The top of the carton may be a gable having panels at the ends of the gables which are slightly larger than the cross section, of the gable roof sides. When the gable is formed, the larger ends are pushed down to create a leverage which closes the top opening more securely. The cut lines which form and define the flaps extend across approximately 80.degree.
