|20150008621||METHOD OF PRODUCING PRESSED PAPER PIECE AND APPARATUS THEREFOR - The objective of the present invention is to provide a method of forming a pressed paper piece by deep drawing a sheet of blank that is primarily made of paper in use of a punch and a die, and a production apparatus for implementing the method, whereby no distinguishable wrinkles are formed in upright portions of the pressed paper piece. The method of producing a pressed paper piece according to the present invention, implemented when deep drawing a sheet-like blank that is primarily made of paper in use of a punch and a die, includes maintaining a predetermined gap between a first blank holder and the die in an outer peripheral region of a process portion of the blank and applying a pressure to a radially inner region thereof via a second blank holder, thereby reducing wrinkling by an effect of integrated functions exerted in both regions of the blank.||01-08-2015|
|20140255630||MOLDED PAPER BODY WITH MINIMAL WRINKLING AND FORMING METHOD THEREOF - The objective of the present invention is to provide a molded paper body in which the outer peripheral portion of a blank primarily of paper is formed in a raised shape using draw processing, wherein the molded paper body eliminates the occurrence of wrinkles causing leaking or instability of adhesion when used as the bottom member of a paper cup or similar paper container and a forming method thereof. The method for manufacturing this molded paper body is to draw-process, with a punch and die, a single blank primarily of paper, and is characterized by use of a holding mechanism to press the outer peripheral portion of the blank between a wrinkle pressing member and the die upper surface, and setting the force applied by the wrinkle pressing member within an appropriate range.||09-11-2014|
|20140084015||HEAT INSULATING CONTAINER - Provided is a heat insulation container which can be easily produced and assembled at a reduced cost, in which a heat insulation grip portion can be formed by a simple operation, in which a strip-shaped projection is maintained and a heat insulation effect can be reliably maintained even when the container is externally gripped, and which can be reliably gripped without being deformed. The heat insulation container (||03-27-2014|
|20120285922||CAP AND COVERED CONTAINER - Provided are a cap capable of being easily and reliably opened and unsealed not limited in design even if an inner cap with a small diameter is used for the cap, producing no refuse after the unsealing, and not unnecessarily large in size, and a container with the cap. When an over cap (||11-15-2012|
|20100224637||HEAT INSULATED CONTAINER - The present invention relates to an improvement of an insulating container wherein either one of an upper portion or a lower portion of an exterior sleeve is fixed to a container main body so as to be fit onto the container main body, and a slit forming section including a group of slits formed on the exterior sleeve is compressed in an up-and-down direction to have the slit forming section project outwardly from the exterior sleeve in order to form an insulating holder.||09-09-2010|
|20090308834||CAP AND COVERED CONTAINER - Provided are a cap capable of being easily and reliably opened and unsealed not limited in design even if an inner cap with a small diameter is used for the cap, producing no refuse after the unsealing, and not unnecessarily large in size, and a container with the cap. When an over cap (||12-17-2009|
|20090081393||THERMAL INSULATION FOAMED SHEET, THERMAL INSULATION FOAMED CONTAINER AND METHOD FOR PRODUCING THE SAME - The present invention relates to a thermal insulation foamed sheet whose foaming height can be kept high by increasing an expansion ratio of foaming cells, thermal insulation foamed container using this and method for producing the same.||03-26-2009|
