摘要:
In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

The invention relates to a method for the manufacture of at least one flexible plastic container, according to which method each container (10) comprises two separate walls (12, 13) facing one another joined at their circumference by a sealed peripheral edge (14), said separate walls defining a storage space of the container (10). According to the invention, at least the following stages are realized: a) Forming a pile of two sheets (26, 27) of plastic material, said sheets (26, 27) being laid one against the other, the surfaces which face one another of these sheets (26, 27) being placed directly in contact with one another without any element acting as an interface, b) Simultaneously shaping said sheets (26, 27) thus laid one against the other in order to define said at least one container (10) without having previously separated these sheets, at least each container (10) being partially formed, said sheets (26, 27) being maintained lying one against the other in at least one section of the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of each container (10) during this shaping and c) Sealing at least partially the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of at least each container (10).

摘要:
A blow-molded foam is provided by foaming and blow-molding the resin material including a polyethylene resin. The foamed resin includes the antioxidant by 300 ppm or more in total. The antioxidant is preferably the combination of a phosphorus antioxidant and a phenolic antioxidant. The optimum amount of phosphorus antioxidant to be included is 250 ppm to 3000 ppm, and that of phenolic antioxidant is 250 ppm to 750 ppm. In the manufacture, the collected resin material and the resin including 300 ppm or more of the antioxidant are melted and kneaded and the foaming agent is mixed thereto to provide the foamed resin, and the foamed resin is blow-molded.
摘要:
The invention concerns a method of simultaneously blowing and filling a container from a thermoplastic polymer preform with a carbonated liquid at ambient temperature having, said carbonated liquid having a defined quantity of dissolved carbon dioxide (CO2) depending on the carbonated liquid beverage, comprising: —stretching the thermoplastic polymer preform (16) placed within a mold (12) during a stretching phase, —starting an injection phase for injecting said carbonated liquid into the preform, the injection phase starting after the stretching phase has started, characterized in that prior to starting the injection phase the carbonated liquid is at a predetermined pressure (P1) equal or greater than the partial pressure (P2) of the carbon dioxide (CO2) defined for said carbonated liquid beverage in the container. The invention also concerns related system.
摘要:
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.
