Abstract
A fluid transfer system suitable for emptying a container or flask closed by a liquid-tight removable frangible closure obtained from a material that can be recycled. Photoprocessing materials are transferred from a first container having the frangible container into an adjoining second container. The frangible closure has a single closure sheet fixed to a lateral skirt for mounting the frangible closure on the spout of the flask, for example with a screw. The flask is emptied by tipping the flask onto a perforation device that perforates a central weakness in the closure sheet which connects with a radial weakness at the seam of the closure sheet and lateral skirt, allowing for lower puncture forces.
