Abstract:
An apparatus for sterilizing containers includes a transport device which transports the containers along a predefined transport path (P), a radiation device which applies radiation (S) to at least some sections of the containers and/or components of the apparatus for sterilization purposes, and a sensor device which detects radiation occurring as a result of the radiation (S) emitted by the radiation device. The apparatus has a shielding element which attenuates the radiation reaching the sensor device in a working mode of the apparatus, and a movement device for moving said shielding element relative to the sensor device.
Abstract:
A device used for plasma-enhanced coating of a container, e.g. a plastic bottle, and/or a container blank, e.g. a container preform, with at least one high-frequency source, at least one gas feed for feeding process gas, and at least one plasma source, e.g. a plasma nozzle. The plasma source has an inner electrode surrounded by a nozzle tube, the plasma source is adapted to be introduced in a container to be coated and configured such that it is able to generate a plasma under ambient pressure, e.g. in a pressure range of 800 to 1,200 hPA, and the plasma can be discharged from a nozzle tube end. The temperature of the generated plasma lies within the range of the ambient temperature, e.g. between 10 and 50 ° C. The nozzle tube of the plasma source includes a longitudinal nozzle tube element and a lateral nozzle tube element projecting laterally from the longitudinal nozzle tube element (201). Plasma is dischargeable through the lateral nozzle tube end.
Abstract:
The present disclosure relates to an apparatus for coating a container e.g. a plastic bottle, by means of a plasma treatment. The apparatus includes at least one gas lance for supplying process gas into the container, and at least one suction valve for sucking off air from the interior of the container. The suction valve has at least one recess, e.g. a centrally arranged one, for receiving or introducing the at least one gas lance into the container, and the suction valve has at least one grounded, gas-permeable, electrical shielding element. The at least one grounded, gas-permeable, electrical shielding element prevents and/or suppresses nearly entirely the ignition and/or burning of plasma in the suction valve.
Abstract:
The disclosure relates to an apparatus for coating a container e.g. a plastic bottle, by means of a plasma treatment. The apparatus includes a high-frequency source, an outer electrode located outside the container to be treated, and an at least partially electrically conducting gas lance for the supply of process gas into the container. The outer electrode is grounded and/or is on the same potential as other parts of the container coating apparatus located outside the container to be treated, such as pressure chamber parts or housing parts. The at least one gas lance is capable of irradiating a high frequency, which can be generated by the high-frequency source, into the interior of the container to be treated.
Abstract:
An apparatus is provided for emptying containers, including first and second holding devices which are suitable for holding first and second regions of containers that are to be emptied, wherein the second region is a distance from the first region, including a movement device which suitable for moving the first holding device towards the second holding device to compress the container located between the first holding device and the second holding device, and including a withdrawal device which has a flow connection to the interior of the container and via which liquid located in the container can be withdrawn as a result of compression of the container, including a drive device for driving the movement device, and including a control device which controls the relative movement of one holding device relative to the other holding device as a function of an internal pressure inside the container.
Abstract:
A sterilization device has a rod-like body which is capable of being introduced through an aperture into an interior space of containers and which acts upon an inner wall of the containers with radiation. A lifting cam produces a movement in a longitudinal direction, of the containers between the containers and the sterilization device in such a way that the containers are capable of being guided over the rod-like body. A movement device is provided which is capable of producing a relative movement in the longitudinal direction of the containers between the rod-like body and the lifting cam and of altering a relative distance between the lifting cam and the rod-like body.
Abstract:
An apparatus (1) for compressing containers (10) and in particular plastics material containers with a first holding device (2) that is suitable for holding a first region (10a) of a container (10) to be compressed, with a second holding device (4) that is suitable for holding a second region (10b) of the container (10) to be compressed, wherein the second region (10b) is spaced apart from the first region (10a), with a moving device (20) that is suitable for moving the first holding device (2) towards the second holding device (4) in an infeed direction (Y), in order to compress the container (10) located between the first holding device (2) and the second holding device (4). According to the invention, the apparatus has a transport device (12) in order to transport the container (10) in a specified transport direction (X) that differs from the feeding direction (Y), wherein the transport device is suitable for transporting the container in this transport direction (X) into a position in which the first holding device (2) comes into contact with the first region (10a) of the container.
Abstract:
The disclosure relates to a device and a method for plasma coating product containers, in particular bottles, the device preferably being a rotary machine comprising a control unit, one or several electrode segments for plasma coating, wherein the electrode segment or each one of the electrode segments can receive at least one product container, and electrodes for coupling out high-frequency radiation. The control unit can automatically control plasma coating in one or each one of the electrode segments depending on process parameters.
Abstract:
A method and apparatus are disclosed for testing and inspecting containers coated by means of a plasma treatment, e.g. plastic bottles, which are coated for instance with amorphous silicon oxide or carbon compounds. The containers are tested by a measuring device trace-gas-analytically, e.g. mass-spectrometrically, for undesired foreign substances, such as acetaldehyde and/or antimony, escaping from the container material after a plasma coating treatment.
Abstract:
