The present invention relates to inflatable bodies or systems with bounding walls or bladder structures and at least one valve assembly thermally bonded thereto. More particularly, the present invention provides a valve assembly for inflatable bodies typically made from a thermoplastic rubber material or the like, which will exhibit significantly increased strength and durability during inflation and while inflated, especially at and around the interface between the air valve assembly and the bounding wall of the inflatable body because of the enhanced strength of the interface through thermal sealing.

The invention concerns a machine for manufacturing plastic items comprising, in series, along the manufacturing line: a rotatable roll (1) of plastic material in the form of at least one strip; a shaper (4) for forming tubes from said strips and means (5) for longitudinally welding said tubes; means (6) for cutting the tubes transversely, arranged so as to form tube sections (10); means for transferring and depositing said sections in holding and moving means; an oven (8) in which said tube sections move; a first turret (9) supporting moulds; means for processing the tube sections in the first turret; means for blowing a pressurised fluid into the moulds; a second turret (14) for discharging the bottles from said moulds.

A method for producing a foamed blow-molded article, which includes extruding a physical blowing agent-containing foamable molten resin downwardly through a annular die to form a tubular foamed parison, clamping the foamed parison between split molds, and then blow molding it. At the latest before completion of the clamping of the foamed parison between the split molds, a gas is blown toward an inner peripheral surface of an upper portion of the foamed parison, the bottom portion of which has been closed, from a gas ejection outlet located within the foamed parison at a position immediately below the annular die to widen the foamed parison.

A container manufacturing device for performing manufacture of a pre-form and a container in a single station via one stop is provided. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to the pre-form to expand the pre-form and to form the shape of the container and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.

To make a sterilization step appropriate in an aseptic filling apparatus. Provided is an aseptic filling apparatus including a step of sterilizing a preform and a step of sterilizing a container obtained by molding the preform, wherein assuming sterilization effects in the respective sterilization steps as X [LRV] and Y [LRV], a relationship of 5≤X+Y≤10 (where Y≥0) is established.

A method for producing a marked container (12), includes the following steps: a first step (E1) of heating, beyond a glass transition temperature, at least one shape-changing portion of the thermoplastic material wall (17) of a preform (14); and a second step (E2) of forming the container by injecting a pressurized fluid into the body (16) of the preform (14) such as to change the shape of the heated portion of the wall (17) by stretching it; and a step (E0) for marking the preform (14), during which a mark (39) is provided on the shape-changing portion of the wall (17) such that the mark (39) is stretched at the same time as the wall (17), during step (E2) after forming.

A method of producing a plastic tank includes preparing a tank wall as a hot semi-finished sheet, in which at least one outer layer of the hot semi-finished sheet is composed of a first material. A reinforcing sheet, composed at least partially of the first material, is then attached to at least one region of the outer layer of the hot semi-finished sheet via a weld connection. The hot semi-finished sheet with the attached reinforcing sheet is then shaped to form the tank wall while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.

A method and a device for producing blow-molded containers, which are sterile at least in some areas, in a blow-molding machine. A preform made of a thermoplastic material is first heated, then stretched by a stretching rod in a blowing station, and then supplied with a pressurized fluid via a blow nozzle, wherein a sterilization device is arranged in the blowing station. The sterilization device has at least one radiation source which emits a sterilizing radiation onto the stretching rod and/or onto the blow nozzle.

A preform coating device is provided with: a conveyance part that conveys a preform; a dispenser that discharges a coating liquid toward the preform; a drier that is disposed along the conveyance route of the conveyance part so as to be separated from the dispenser, and that dries the coating liquid applied to the preform by irradiating, with infrared rays, the coating liquid applied to the preform; and an air sending mechanism that is disposed along the conveyance route of the conveyance part so as to be separated from the drier and that sends air toward the preform irradiated with infrared rays.

A liquid blow molding method of molding a synthetic resin preform having a mouth portion into a liquid container of a predetermined shape, including: an air-liquid replacement step of supplying a liquid into the preform from the mouth portion through a blow nozzle and discharging the air inside the preform to the outside; an air-liquid separation step of separating the air from the liquid inside the preform by vibrating the preform; and a blow molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid into the preform from the mouth portion through the blow nozzle, after the air-liquid separation step.
