Method for manufacturing resin wide-mouthed container, manufacturing device, and resin wide-mouthed container
A method for manufacturing a resin wide-mouthed container includes at least: injection-molding a bottomed preform made of resin; and blow-molding the injection-molded preform. During the injection molding, the preform is injection-molded such that an overhanging section overhanging outward is formed on an outer peripheral section of a first lip section closer to a first body section than a flange section, and while the first lip section, which is provided with the overhanging section, is held by a lip mold, which has a recessed section that engages with the overhanging section, the preform is separated from an injection molding die.
Luggage room board
A luggage room board includes the luggage room board main body made of resin and is configured to be opened and closed. At one of ends of a non-woven fabric, a concave portion is provided on a surface of the luggage room board main body to which the non-woven fabric is attached, and the end of the non-woven fabric is attached so as to enter the concave portion. The concave portion is formed such that a depth gradually increases toward the end of the non-woven fabric. The depth of the concave portion at the end of the non-woven fabric is approximately same as the thickness of the non-woven fabric or larger than the thickness of the non-woven fabric. The concave portion is provided at the end of the non-woven fabric on a side of the rotation center line.
Mold for blow molding, method for manufacturing resin container using same, and resin container
A blow molding mold in which a holding mechanism is independently provided to a bottom mold and is configured to be capable of gripping a protruding portion provided to a bottom portion of a preform independently of a gate portion, and a rotation mechanism is configured to be capable of rotating the bottom mold, relative to a neck portion of the preform which is in a stationary state held by neck molds, in a state where the protruding portion is gripped by the holding mechanism.
Polymer vials with substantially flat bottoms and injection stretch blow molding methods for making the same
Disclosed are polymer vials (110, 210) and injection stretch blow molding methods for making the same. A polymer vial has a base (112) having a base surface area and a sidewall (114) extending up from the base. The base and sidewall define an interior (116) configured to house product, the sidewall narrowing at an upper section of the vial to form a neck leading to an opening that provides access to the interior. The vial is optionally round and symmetrical about a central axis, a lower portion of the sidewall including a first surface that is outwardly curved along a first radius having an imaginary center positioned within the vial. The base is positioned below the first surface and is substantially flat such that at least 80% of the base surface area has a standing base surface occupying a single plane.
Method for producing resin vessel made of resin, mould unit and moulding apparatus
Provided is a method for manufacturing a container 10 made of resin, the method including an injection molding step S1, a temperature adjustment step S2, and a blow molding step S3. In the temperature adjustment step S2, a preform 11 is accommodated in a cavity mold 31, an air introduction member 32 is brought into airtight contact with the preform 11, the air is supplied from a blowing port of the air introduction member 32 into the preform 11, and the air is discharged from a discharge port of the air introduction member 32 to an outside of the preform 11, so that the preform 11 is in close contact with an inner wall of the cavity mold 31 and is cooled.
POLYMER VIALS WITH SUBSTANTIALLY FLAT BOTTOMS AND INJECTION STRETCH BLOW MOLDING METHODS FOR MAKING THE SAME
Disclosed are polymer vials and injection stretch blow molding methods for making the same. A polymer vial has a base having a base surface area and a sidewall extending up from the base. The base and sidewall define an interior configured to house product, the sidewall narrowing at an upper section of the vial to form a neck leading to an opening that provides access to the interior. The vial is optionally round and symmetrical about a central axis, a lower portion of the sidewall including a first surface that is outwardly curved along a first radius having an imaginary center positioned within the vial. The base is positioned below the first surface and is substantially flat such that at least 80% of the base surface area has a standing base surface occupying a single plane.
