20090218390 | Bio-degradable cup and method for making the same - A bio-degradable cup includes a foam cup and a paper cup which is securely received in the foam cup. The paper cup includes a bio-degradable film coated to an inside thereof. The paper cup is formed by cutting a paperboard and folded to be the paper cup. The foam cup is made by preparing a foam board made by bio-degradable plastic which is treated by way of super-critical carbon dioxide extrusion, the foam board is cut into pieces and each piece is made to be the foam cup. The foam cup is applied with a heat treatment to obtain a sticky inner surface to which the paper cup is securely connected. A lip is formed around an outer top edge of the foam cup. | 09-03-2009 |
20090220711 | Bio-degradable cup and method for making the same - A bio-degradable cup includes an IXPE foam cup and a paper cup which is securely received in the foam cup. The paper cup includes a bio-degradable film coated to an inside thereof. The paper cup is made from a paperboard with a bio-degradable film coated and the paperboard is cut, folded and heat-pressed to be the paper cup. The foam cup is made from a foam board made by IXPE and the foam board is cut, shaped and folded into pieces and each piece is made to be the foam cup by way of heat pressing. A heat treatment is applied to an inside of the foam cup to obtain a sticky inner surface of the foam cup and the paper cup is securely connected to the sticky inner surface of the foam cup. A lip is made around an outer top edge of the foam cup. | 09-03-2009 |
20090250849 | Method of manufacturing environmenetal protection container - A method of manufacturing an environmental protection container includes the following steps: PLA (poly lactic acid) or biodegradable raw materials are made to become a film. The film is a film bundle or an extended roll. The film then is rolled up and placed into a mold to process with in-mold crystallization and modification. By using in-mold crystallization procedure, biodegradable molecules can resist heat to achieve 120 degree centigrade after modification. The crystallization procedure can be processed in the mold and the film can be directly stamped and formed according to required shapes after modification, thereby enhancing heat resistance and increasing environmental protection efficiency for the environmental protection container. | 10-08-2009 |
20090277567 | Method of fabricating substrate of paper-made food container - A method of fabricating a substrate of a paper-made food container includes: (1) a paper layer of an original paper roll is processed with preheating and electrostatic process in advance, and a gelatin film then is coated on a single face lamination or double face lamination of the paper layer to form a complex layer. Alternatively, the double face lamination does not to be coated. The gelatin film is biodegradable material or non-biodegradable material. (2) Biodegradable material or non-biodegradable material is utilized to prepare an electronic cross-linked foam layer as a roll. (3) The complex layer is conveyed to the continuous thermal laminator. The thermal processing device of the continuous thermal laminator then is utilized to perform melting point heating for one face lamination or double face laminations of surfaces between the complex layer and the electronic cross-linked foam layer. Two rollers of the rolling (laminating) device then roll the complex layer and the electronic cross-linked foam layer to form the substrate that can be subsequently cut to make various food containers having heat insulation, warm-keeping and cold insulation functions. | 11-12-2009 |
20100065622 | Structural improvement for cup container - A structural improvement for a cup container includes the following structures. An internal layer paper cup having an internal paper cup bottom is bonded to a bottom of the cup container. A foam layer is bonded to an exterior of the internal layer paper cup. An external layer paper cup then is bonded to an exterior of the foam layer. A foam bottom and an external paper cup bottom are bonded to an external bottom of the internal paper cup bottom in order. The internal surface of the internal layer paper cup and an upper of the internal paper cup bottom are coated with waterproof layers. The foam material of the foam layer can be a biodegradable material, or non-biodegradable materials. The foregoing waterproof layers can be a biodegradable material, or can be a non-biodegradable material. | 03-18-2010 |
20100075076 | Spread structure of a multiple layers container - A spread structure of a multiple layers container and the multiple layers container includes at least one paper layer and at least one vesicant layer. The paper layer and the vesicant layer are made by a unitary plate of cardboard sticking to a vesicant plate being pressed by mold, cut, and formed. A predetermined sticking portion on a spread substrate of the paper layer and the vesicant layer is pressed so that a thickness thereof is thinner than any other portions not being pressed or approximate to a thickness of the paper layer. Such substrate can be applied to a conventional container making machine for further processes. | 03-25-2010 |
20100137118 | Vesicant cup - A method for manufacturing a vesicant cup includes a cut fan-shape vesicant plate having thinner upper and lower arcs formed as upper and lower edges. The vesicant plate is rolled and pressed on two stacking joints formed on left and right edges of the vesicant plate respectively. The pressed joints are thinner than other portions of the cup body not being pressed. A lip is formed by rolling up the upper edge outward, and a bottom join is formed by folding up the lower edge inwards. An edge of a vesicant cup bottom is bent downwards as a round joint for connecting and sealing the bottom joint of the vesicant cup body. A thickness of the round joint, bottom joint and the vesicant cup body corresponding to the round joint is thinner than other portions of the vesicant cup body not being pressed. | 06-03-2010 |
