摘要:
A method and a device for the manufacture of plastic packagings, the same being manufactured by stretch blowing a bottle-like preliminary packaging which is, after completion, treated by means of a laser and thus reshaped to the final packaging. Also, a plastic container manufactured according to this method and with this device.
摘要:
The invention relates to a method and a device for heating preforms of a thermoplastic material, the preforms, after having been heated, being subjected to a reshaping operation, and microwaves being applied to the preforms, at least during a portion of the period of heating, in a resonator.
摘要:
A cleaning assembly for containers, particularly for bottles, having a conveying device on which the containers are arranged by means of a receptacle means. To economically and ecologically improve the cleaning assembly, the receptacle means contains a liquid-tight tubular for an individual cleaning of the containers.
摘要:
A method for pre-treating preforms (12) made of thermoplastic plastic, before they are shaped into containers (13) by means of a stretch blow molding process and filled with liquid. The preforms (12) are tempered and sterilized for the subsequent stretch blow molding process. Tempering of the preforms (12) is carried out by means of microwave radiation and by sterilization of the preforms (12) during the pre-treatment.

摘要:
A device for the stretch blowing of plastic containers in a continuous single-stage process, having at least one injection rotor, with injection molds for preforms, which are fed via controlled valves from an extruder head and by way of a melt distributor from a central extruder, wherein the axis of the extruder is placed at least essentially in the axis of the injection pipe, and at least the extruder head and the melt distributor can be permanently and synchronously rotationally driven by the injection rotor. A method where, during the manufacture of each preform in the injection mold, injection molding phases and a compression molding or dwell pressure phase are combined and superimposed.
摘要:
An apparatus (1) for sterilizing containers (10), comprising a treatment head (5) which has an exit window (8) through which charge carriers can pass, comprising a charge carrier generation source which generates charge carriers, and comprising an acceleration device (6) which accelerates the charge carriers in the direction of the exit window (8). According to the invention, the cross section of the treatment head (5) is dimensioned such that the treatment head (5) can be guided through the mouth of the container (10), and the acceleration device (6) accelerates the charge carriers in such a way that the charge carriers exiting from the exit window (8) can be aimed preferably directly onto an inner wall (15) of the container (10).

摘要:
The invention relates to an apparatus for applying labels to containers. In one embodiment according to the invention, the process of applying the labels to the container is carried out by means of a laser unit. In another embodiment according to the invention, a cutting unit is provided for the apparatus, which cutting unit likewise uses a laser and is arranged at least partially inside a cutting roller. In preferred embodiments, the complete application process, i.e. in particular including the bonding of the end sections of the label, is carried out by means of the laser unit.
