Abstract
A dispensing module for use in the dispensing of pressurized liquids, foams, gels or the like comprises the combination of a dispenser valve (12) and a flexible bag (24) which is bonded thereto. The bag (24) is intended to be located within an outer container (22) by way of an opening (23) in the latter that can be closed with a lid (25). Disposed within the bag (24) is a delivery nozzle (58) that can be connected to the valve body (14) of the dispenser valve (12) through the bag material with the interposition of a sealing ring (32) in such a way that between the interior (52) of the bag and the valve body (14) fluid communication is maintained. The delivery nozzle (58) and/or the valve body (14) is made of a material that is fracture-proof and in particular not permeable to organic media. The portion (34) of the delivery nozzle (58) immediately adjacent to the bag (24) is provided with a surface or a covering (36) of a material, such as polyethylene, polypropylene or polyamide, which can be bonded to the bag material.
