Closing device for containers having a sterile space

Abstract

The invention relates to a device for closing containers with closures comprising a closing head (2) that attaches the closures to the containers, wherein said closing head (2) can be moved relative to the closures with a first movement type and is arranged within a sterile space (8) with a first movement unit (4) for producing a movement of the closure with the first movement type, wherein said first movement unit (4) is arranged at least partially outside the sterile space (8), wherein the sterile space (8) is bounded by at least one first wall (12) and the device comprises a ring-shaped channel (14) into which said first wall (12) protrudes, wherein the ring-shaped channel (14) can be moved relative to the first wall (12) and can be filled with a fluid medium, and wherein the first movement unit (4) is arranged within the channel (14) at least in sections.

Description

technical field [0001] The invention relates to a device for closing a container. Background technique [0002] Devices for closing containers have been known in the prior art for a long time. In factories producing beverage containers, these containers are usually filled with beverages and then closed with closures, for example screw caps or metal bottle caps. [0003] In this case, special situations often occur, for example, when injecting juice. In this case, the entire handling of the containers and their closures must take place in a sterile or clean room. At this time, a longitudinal movement of the head relative to the longitudinal direction of the container is also necessary to a certain extent for the closing step. Since it is generally not necessary to place all components that must perform this longitudinal movement inside the sterile room (as this would violate the principle of keeping the latter sterile), efforts have been made to place as many drive element...
