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.

Dependent claims

A dispensing module including an outer container having an open end closed by a closing lid and having a lid opening including a rim for dispensing of a pressurized medium from the container, comprising a bag of flexible material, said bag being capable of location within said outer container through said open end and which opening is closed by the lid, a dispenser valve including a valve body attachable to the rim of the lid opening, and having a discharge aperture,

a discharge nozzle (58) disposed within the valve body and defining a discharge channel and aligned with said discharge aperture to the valve body,
spring means coupled to said discharge nozzle and said valve body and supporting said discharge nozzle, said discharge nozzle for displacement between a closed position and an open position, said spring means urging said discharge nozzle to the closed position,
a resilient sealing member disposed between the rim and the valve body and aligned with said discharge nozzle, said discharge nozzle engaging said sealing member in the position and thereby closing the discharge aperture and thereby said discharge channel;
a delivery nozzle (58) disposed within said bag and having a connecting portion abutting the bag, said bag being located between the nozzle and the valve body, said delivery nozzle is formed substantially completely of a fracture-resistant material that is substantially impermeable to organic media, and having said connecting portion having a surface bonded to the bag;
and
a sealing means between said delivery nozzle and the valve body to permit fluid communication only from the interior of the bag through said delivery nozzle into the valve body.
