  • Patent number: 6616586
    Abstract: A container manufacturing method and device. The container manufacturing method includes steps of mixing, board-making, molding, guiding/crimping and demolding. Lower protruding guide bodies are arranged along the circumference of the mold cavity of the lower mold seat of the container manufacturing device at intervals. Upper protruding guide bodies are arranged on the press board and aimed at the intervals between the adjacent lower guide bodies. In the step of guiding/crimping, when the press board is pressed down by an oil pressure cylinder, the interlaced upper and lower guide bodies clamp and press the circumference of the board body to form regular crimps thereon. Therefore, when the upper mold block presses the board body into the mold cavity, the material can be evenly distributed and flowed so that the wall of the molded container can have uniform thickness.

  • Patent number: 6520900
    Abstract: Methods for setting-up a female blanking die for a die cutting machine for die cutting and/or blanking a carton blank, and universal press frames for use in such setting-up are all provided herein. The first stages in the erection of the female blanking die, which includes a rectangular framework of a front rail, a rear rail and two side rails, involve accurate placement of a template within the rectangular framework. All the rails are provided with a dovetail groove along its inside edges. This is achieved by the use of centre line orientation cylinders on a template, a centre line rod through aligned holes in the centre line orientation cylinders and centre line brackets at the precise centre point of the front and the rear rails. The template is mounted atop the centre line brackets by means of the centre line rod and rests loosely on template corner locking clamps.

  • Patent number: 6312370
    Abstract: A machine for container formation by folding a die-scored paperboard structure to close flaps shaped by the scoring that serve as the top and bottom of the container. A scored paperboard sheet is loaded onto a male pedestal inner pattern such that the foldable top and bottom container portions extend beyond the pattern, whereupon armature driven semicircular outer patterns, having upper and lower fingers adapted to be driven by corresponding fluid driven pin stabilizers, close upon the sheet. While closed over the sheet, the pins are activated to move the fingers inward on the inner pattern and force fold the container along the score lines, followed by automatic retraction of the pins and outer patterns. The container is thus pre-folded in preparation for shipping as a flat paper form that is ready for folding on the crease lines thus formed. One or both flaps of the container can be folded along the crease lines to form a closure at one or both ends.
