A device for forming plastic parisons into plastic containers includes at least one forming station arranged on a conveying device and configured to form plastic parisons into plastic containers by applying a gaseous medium, the forming station includes an application device configured to apply the flowable medium to the plastic parisons, and includes a pressure supply device and/or is in fluidic connection with a pressure supply device configured to provide the flowable medium at a prespecified pressure, wherein pressure provided by the pressure supply device is greater than pressure required and/or used for the application to the plastic parisons, wherein the device includes at least one valve device which controls application to the plastic parisons, which valve device is configured to interrupt the supply of air into the container when the pressure of the flowable medium within the container has reached a prespecified pressure level.

An injection stretch blow-molded (ISBM) container prepared by way of injection molding a tubular preform followed by reheating and concurrently stretching and blow-molding the heated preform into the container. The container and preform comprise from 70 wt. % to 97.5 wt. % of a semi-crystalline polyolefin composition comprising one or polymers selected from polyethylene polymers and polypropylene polymers and from 2.5 wt. % to 30 wt. % of an alicyclic polyolefin composition, wherein the alicyclic polyolefin composition has a glass transition temperature, Tg, of from 80° to 145° C.

By providing a depressed portion 7 in a container main body 1a, forming a thick portion 5a in a covering layer 5 on an edge portion 7b of the depressed portion 7, and forming a thin portion 5b adjacent to the thick portion 5a in the covering layer 5 on a bottom surface 7a side of the depressed portion 7, when a synthetic resin container including a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body is discarded, the container main body and the covering layer can be easily separated.

A method for forming plastic parisons to plastic bottles includes the following steps: introducing in a blow mold a plastic parison to be expanded, the blow mold having at least two lateral parts and a base part that is mobile in relation to said lateral parts in a longitudinal direction of the plastic parison; inserting a rod-shaped element in the interior of the plastic parison through a mouth of the plastic parison; applying a first pressure the plastic parison, applying a second pressure to the plastic parison, the second pressure deviating from the first pressure and being higher than the first pressure, applying a third pressure to the plastic parison, the third pressure deviating from the second pressure and being higher than the second pressure. The base part is advanced in the longitudinal direction of the plastic parison while at least temporarily applying the second pressure to the plastic parison.

To simply sterilize a blow-molding machine.

A mist or gas of hydrogen peroxide or a mixture thereof is introduced through a valve block (14) disposed adjacent to a molding die (13), thereby sterilizing at least the molding die (13) and an extension rod (15) that extends into the molding die (13) through the valve block (14).
