  • Patent number: 5795071
    Abstract: A standing pouch having a recess formed on the upper part of a side of the body of the pouch and spaced from the upper side of the body, and a relief connecting with the inside of the pouch surrounded by an end of the upper side, the upper part of the side and the upper part of the recess and becoming a spout by removing the end portion of the relief. The standing pouch can ensure transfer of a fluid material contained therein to another container without the occurrence of overflow problem. The standing pouch permits the variation of the discharged amount to be small and less dripping occurs.

  • Patent number: 4992129
    Abstract: A method for thermal transfer printing by heating a transfer sheet having a printing ink layer formed on a base sheet with a hot roll, wherein the base sheet comprises biaxially stretched plastic film, and, at the same time, pressing with the hot roll the transfer sheet against a substrate for printing, thereby transferring the printing ink layer to the substrate, wherein the substrate for printing is preheated prior to the pressing, and a transfer printing machine having a supplying roll axle for a roll of transfer paper urged to rotate in the rewinding direction by an urging force, a heat roll for performing heat transfer by pressing one surface of the transfer paper on which printing ink is not applied so as to cause the transfer paper to pressingly contact an object of transfer with a surface to which printing ink has been applied, and a takeup roll axle adapted for intermittently rotating and rewinding, for each rotation thereof, one pitch of the transfer paper having undergone the transfer, an improveme

  • Patent number: 4988013
    Abstract: A container lid structure made essentially of plastics. The lid structure includes a lid frame and a lid plate. The lid plate includes an inner layer comprising a metal foil coated at the opposite sides by plastic layers and connected at the peripheral portion with the lid frame and a core made of a material which is not adhesive to or has a weak bonding power with the plastic material for the lid frame and for the plastic layer of the inner layer. The core is laid over the inner layer with the peripheral portion in an abutting relationship with the inner periphery of the lid frame. A holding member is formed on the core and bonded to the inner layer through apertures in the core. A pulling tab is also formed on the core and bonded to the inner layer through an aperture in the core.

  • Patent number: 4909888
    Abstract: A transfer printing method and an apparatus therefor which applies an induction heat generation jacket roller based on the principle of exothermic low-frequency induction heating to a heat roller, supplies continuously a printing layer disposed on a transfer film and an object of transfer whose drum is cylindrical to the roller surface of the heat roller in order to make it possible to transfer simultaneously to a plurality of objects of transfer and can prevent transfer slippage by adjusting in advance the position of the printing layer relative to each object of transfer.

  • Patent number: 4872590
    Abstract: A plastic can is formed of a body member including a content protecting layer which is a tubular body formed by folding back and outward one side edge of a laminated film, bonding the folded parts such that air bubbles are not entrapped thereunder, overlapping the other side edge of the same laminated film on the bonded surface and bonding the side edges such that air bubbles are not entrapped between the side edges. An additional sheet is bonded all over the external surface of the laminated film except for a projecting stripe formed by the bonding of the side edges. A surfacing plastic layer covers the additional sheet and the projecting stripes. An apparatus is provided for forming the can, smoothing the surfacing plastic layer, forming the tube into can bodies, shaping the can bodies and sealing, lids on the ends of the cans.
