Contamination-free, flexible closure system for use on at least partially flexible containers

Abstract

A closure () has two profiled strips () for an at least panially flexible container () for connecting a first container () to a second container () in an environmentally sealed manner and in a closed docking position, and for conducting a flow in a flow direction (D) through the closure () from the first container () into the second container () in an environmentally sealed manner and in an open docking position. The second container () has an identical closure () facing the first container (), and, in the open docking position, is in engagement with the closure () of the first container (). Together with the closure () of the first container (), a flow channel () is defined for the through flow in the flow direction (D). The closures () can be docked to each other and opened jointly in a single step by a separate slider. Due to the dual functional nature of all the closure elements, no closure element () is exposed in the channel-upward direction to the material to be transferred. A slider () connects and separates the closures (), and has an insenion side (), on which the closures () can be insened into the slider () in insertion directions (A, B), which form an acute angle, and an output side () opposite the insenion side (), on which the closures (), which are connected to each other and are open, can be led out from the slider () in a common slide direction (C).
