Estimating the term…
Provided is an apparatus for forming plastic preforms into plastic containers, having a blow mould which forms a cavity within which the plastic preforms can be expanded to form the plastic containers, and having an application device which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, wherein the application device is placed against a mouth area of the plastic preforms in order to act upon these with the flowable medium. The application device forms at least one first flow channel for the flowable medium, which guides and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper and, in particular, cool this inner wall.
An apparatus for forming plastic preforms into plastic containers, having a blow mould which forms a cavity within which the plastic preforms can be expanded to form the plastic containers, and with an application device which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, wherein the application device can be placed against a mouth area of the plastic preforms in order to act upon these with the flowable medium, wherein the application device forms at least one first flow channel for the flowable medium which guides and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper this inner wall, wherein the application device has a tubular body which projects into the plastic preform during an expansion of the plastic preform and which forms a flow path of the flowable medium which does not reach the inner wall of a mouth region and the flow path is given by a distance between the tubular body and a wall surrounding this tubular body.
An application device for acting upon plastic preforms with a gaseous medium in order to expand these plastic preforms, having an annular sealing section which is suitable and intended, during the application of the plastic preform with the gaseous medium, to seal off the air flow entering the plastic preform from an environment, and having a tubular body, which during the expansion process projects at least partially into the plastic preform to be expanded, wherein the application device forms at least one first flow channel for the flowable medium, which conducts and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper this inner wall, wherein the application device has a tubular body which projects into the plastic preform during an expansion of the plastic preform and which forms a flow path of the flowable medium which does not reach the inner wall of a mouth region and the flow path is given by a distance between the tubular body and a wall surrounding this tubular body.
A method for forming plastic preforms into plastic containers, wherein the plastic preforms are expanded within a blow mould by being acted upon by a flowable medium and are expanded by an application device with the flowable medium, wherein the application device is applied to a mouth area of the plastic preforms, wherein the application device forms at least one first flow channel for the flowable medium which guides and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper this inner wall, wherein the application device has a tubular body which projects into the plastic preform during an expansion of the plastic preform and which forms a flow path of the flowable medium which does not reach the inner wall of a mouth region and the flow path is given by a distance between the tubular body and a wall surrounding this tubular body.
