A method of producing a lipped molded article comprising the steps of forming a molded article having an opening portion by papermaking and outwardly curling the peripheral wall portion which constitutes the opening portion to make a lip. The method is characterized in that the inner surface of the molded article is coated with a resin layer to make a multilayer molded article, the part to be curled of the peripheral wall portion of the molded article is impregnated with a liquid, and the part to be curled is subjected to curling processing while or after being heated.

Method for producing flanged molding

A heat-insulating container having a first fiber layer () with a prescribed density and a second fiber layer () which is formed inside the first fiber layer () and has a lower density than the first fiber layer (). The first fiber layer () is 0.2 to 1 mm thick, and the second fiber layer () is 0.4 to 3 mm thick, with the total thickness of the first fiber layer () and the second fiber layer () being 0.6 to 4 mm.

Heat insulating container

A method of producing a pulp molded article. The method feeds a pulp slurry to a cavity of a papermaking mold having a prescribed cavity shape to form a pulp preform including a main part having an opening and a separable part having a flange and connected to an edge of the opening. A pressing member is inserted into the preform, the pressing member is expanded to press the preform toward the papermaking surface, the preform is removed from the papermaking mold, and then the preform is cut at a joint between the separable part and the main part.

Method of manufacturing pulp mold formed body

A method for producing a pulp molded article () comprising the steps of supplying a pulp slurry into the cavity () of a mold () composed of a set of splits (and), the set of splits (and) being assembled together to form the cavity () with a prescribed configuration, to form a pulp deposited body (), feeding a fluid into the cavity () to press the pulp deposited body () onto the inner wall of the cavity () for dewatering.

Method for producing pulp molded article

A method for producing a pulp molded article ( ) comprising the steps of supplying a pulp slurry into the cavity ( ) of a mold ( ) composed of a set of splits ( and ), the set of splits ( and ) being assembled together to form the cavity ( ) with a prescribed configuration, to form a pulp deposited body ( ), feeding a fluid into the cavity ( ) to press the pulp deposited body ( ) onto the inner wall of the cavity ( ) for dewatering.

A method for producing a pulp molded article is disclosed. The method comprises the steps of forming and drying a pulp molded precursor ( ). The drying step includes a first step and a second step. In the first step, the precursor ( ) is set in a cavity of a heating mold, and is hot-pressed. The cavity has a configuration in conformity to the contour of the pulp molded article to be produced. In the second step, the hot-pressed precursor ( ) is taken out from the heating mold and is heat-dried in a drying furnace.

A papermaking mold for producing a pulp molded article comprising a core of prescribed shape which has a plurality of holes for fluid passage interconnecting the outside and the inside and is made of an elastically deformable material and a fluid-permeable material which covers the outer surface of the core, the fluid-permeable material being capable of forming passages for a fluid in its thickness direction even when pressed and deformed.

Papermaking mold for producing pulp molded article, method of producing pulp molded article using the mold, and apparatus for producing pulp molded article

A method of producing a pulp molded article comprising a papermaking step in which a pulp slurry is fed to the surface of a papermaking mold having suction paths, and water contained in the pulp slurry is sucked through the suction paths whereby the pulp is deposited on the surface to form a wet preform, and a dewatering step in which the wet preform is dewatered, wherein the temperature of the fed pulp slurry is raised while the pulp is being deposited on the surface.

Method of manufacturing pulp mold formed product

A method for producing a pulp molded article ( ) comprising the steps of supplying a pulp slurry into the cavity ( ) of a mold ( ) composed of a set of splits ( and ) the set of splits ( and ) being assembled together to form the cavity ( ) with a prescribed configuration, to form a pulp deposited body ( ), feeding a fluid into the cavity ( ) to press the pulp deposited body ( ) onto the inner wall of the cavity ( ) for dewatering.

Pulp molded article

A process for producing a pulp molded article comprising inserting a hollow inflatable pressing member which has been made small so as to have smaller cross-sectional contour into a cavity of a mold in which a pulp layer has been formed, and feeding a pressurizing fluid into the inserted pressing member to inflate the pressing member thereby to press the pulp layer onto the inner wall of the cavity

Process for producing pulp molded article

A blow molding process in which a gas is blown into a parison within a mold to inflate the parison, the parison makes intimate contact with a mold shaping portion to form a hollow molded product, and the gas within the hollow molded product is discharged for cooling, the blow molding process including setting an internal gas pressure of the hollow molded product to 5 to 8 kgf/cm,; and discharging a gas satisfying an expression, F&gE;10&times;W. while blowing, wherein F is a gas flow rate (N1/min) and W is a hollow molded product weight (g).

Blow molding process

In a disk cartridge having an imbalance of the flow of resin at the time of injection molding due to the lateral asymmetry of recesses on which a shutter slides, the thickness of each shell of the disk cartridge is balanced laterally by forming a projection in one region which is the left half of the shell or the right half of the shell with respect to the center line C of the shell and occupies a larger part of the area of a shutter sliding recess and by forming a recess in the other region which occupies a smaller part of the area of the shutter recess.
