Abstract

An arrangement for the opening of rigid, collapsible enclosures or of flexible bags, characterized in that this arrangement consists of a housing having a receiving container arranged therein which is adapted to be opening and closed by an opening lid, in which there are arranged scissors-like knives which are openable and closeable along a rotary axis such that a plurality, parallel-horizontally arranged, fixed knives are in operative connection with parallel, at an angle upwardly and inwardly arranged knives, whereby the movable knives are opened to such an extent and closed through pull rods by use of a motor that, through this movement, the liquid which is contained in the enclosures or bags can flow off into a discharge and thereafter the receiving container arranged on the rotary axle is enabled, by use of a motor, to be rotated so far downwardly until the enclosures can without external contact be expelled from the housing through a rinsing cone and thereafter the receiving container can be turned back for a renewed insertion.
