Assembly for dispensing product of pasty fluid consistency, which includes a container (2) made of flexible material containing the product and a dispensing head which includes a dome (3) and is equipped with at least one dispensing orifice (4) capable of being closed by a movable stud (7) carried by an elastically deformable membrane (6), the container (2) and the dome (3) constituting a single piece obtained by moulding, a rigid insert (5) being put into position at the base of the dome (3) and delimiting a space (25) between the insert and the dome (3), the insert (5) including channels (23), which brings the space (25) into communication with the container (2), and carrying, opposite the orifice (4), the deformable membrane (6), the insert (5) consisting of a disc (14) through which are provided the channels (23) and of a support element (15) carrying the membrane (6), solidly attached to the disc (14 ), and arranged in the central region of the disc (14) which includes a circular plate (16), the central region of which is solid and which is moulded as a single piece with an annular element (17) which forms, together with the plate (16), a cylindrical blind housing (14a) inside which the support element (15) is fixed, the annular element (17) carrying, at its upper part, a flange (19) coming to bear against a step (3a) provided inside the dome (3) at the junction between the skirt (11) and the cupola (13).
A container comprises a flexible body member (2) closed by a cap portion (26) having an outlet (28) therein, and a control assembly within the cap portion for controlling liquid flow from the body member (2) to the outlet (28), the control assembly comprising an integrally moulded seating (6) for location on the body member (2), including an outer annular sleeve (8) and an inner valve support chamber (12) and a control valve (16) of a one piece plastic moulding located on the seating (6) to define a closed volume therebelow and to seal the outlet, the closed volume being vented to atmosphere, the arrangement being such that, on pressurisation on the interior of the body member (2), the pressurised liquid flows between the sleeve (8) and the chamber (12) to distort the control valve (16) and enable flow through the outlet (28), and, on release of said pressure, the control valve (16) returns to a position sealing the outlet (28).
A spray head (1) for spraying fluid through a spray orifice (7), the head being provided with an expulsion channel (5), and with a closure member disposed in fixed manner in the expulsion channel (5), upstream from the spray orifice (7), the closure member comprising a closure element (9) which, at rest, closes off the spray orifice (7), and an elastically-deformable portion (10) supporting the closure element (9) for opening the spray orifice (7), the spray head (1) further being provided with a spray profile, the spray head being characterized in that the spray profile is formed on the closure member.
The present invention relates to a liquid dual phase cosmetic or pharmaceutical composition comprising an oil phase and an aqueous phase, the composition containing as a demixing agent a quaternary nitrogen-containing ether substituted alkoxylated alkyl glucoside. The compositions of the invention are particularly useful as makeup removers.
A dispenser (1) includes in a casing (2) with a volume-variable storage chamber (11) for the medium, a discharge closure (10), whose closure member (50) is located directly adjacent to the discharge nozzle (8) and whose pressure dependently operating control device (18) is arranged completely within the casing (2). The control device (18) is located on a support unit (5) separate from the casing (2) and defining ducts (28, 29, 38, 47) for two separate media. Thus, while achieving simple construction and assembly, a contamination of the stored medium can be prevented.
A multiple-dose bottle with dosage nozzle for liquids, particularly for pharmaceutical products, is deformable and has a nozzle (2) which comprises a valve (3) made of flexible material which can be coupled to the mouth (4) of the bottle (1) and has a plurality of passages (5) for the flow of the liquid and a cap (6) made of substantially rigid material which is fitted hermetically on the valve (3) and is provided, in an upward region, with a dispensing opening (7), compression of the bottle (1) producing the compression of the valve (3), the flow of the liquid between the valve (3) and the cap (6), and the release of the liquid through the dispensing opening (7).
