Benefits of technology

The invention provides methods and tools that improve how well an injection molded or extruding material can be filled into containers made from this type of resin. This results in improved production rates compared to traditional processes like blow-moldings.

Problems solved by technology

This patents describes various technical problem addressed during production processes used in injection molders (injection moldings) where large quantities of plastiphones made up of polyethylene terephtalate(PET). Existing techniques involve filling empty containers before final packaging, but current solutions require expensive equipment and may result in quality issues due to inspections taken manually. There is therefore a desire for improved ways to produce plasma bottled plates containing specific gases like O2.

Embodiment Construction

[0077]Examples of embodiments are described below with the aid of the figures. In the figures, elements which are identical or similar, or have identical effects, are designated with identical reference signs, and repeated description of these elements is in part dispensed with in the description below, in order to avoid redundancy.

[0078]In FIGS. 1 to 4, a device 1 for manufacturing plastic containers and for filling them with a fill product is shown schematically. For manufacturing the plastic containers, a blow mold 2 is provided, which has a cavity 20 with an inner wall 22 that corresponds to the outer contours of the plastic container that is to be manufactured. In the blow mold 2, a plastic container can be manufactured in a manner known in the art from a heated preform by means of blow molding or stretch blow molding. In the stretch blow molding process, the heated preform is pre-stretched with a stretching rod and simultaneously pre-inflated, then fully blow molded by means of p

Abstract

Methods for manufacturing a plastic container and for filling it with a fill product are described. The methods include introducing a perform into a blow mold, pressuring the preform with a blowing medium, evacuating the interior space of the container to an underpressure, and introducing a fill product in the interior space at an overpressure.
