Abstract: A valve for distributing two fluids contained in a rigid flask by propulsion, the first fluid contained in a first flexible pouch, and the second fluid in the flask so as to be isolated from the first fluid before the fluid leaves through the valve. When the valve is placed on the flask, an internal part of the valve is inside the flask, an external part of the valve is outside the flask. A first passage which can be closed connects the inside of the first pouch and the space surrounding the external part of the valve, and a second passage which can also be closed connects the space intended to receive the second fluid and the space surrounding the external part of the valve. The valve has a second flexible pouch for receiving the second fluid, which is fixed to the valve and placed around the first pouch.

Abstract: The invention relates to a cap comprising a base with means for fixing it to a container, a top fixed to the base by a hinge, closure means consisting of a first closure means and a second closure means, one on the base and the other on the top, the closure means working together to keep the top in a first position in which it is closed against the base, release means for moving apart from each other the first closure means and the second closure means and means for lifting the top. In accordance with the invention, the means for lifting the top consist of at least one leaf spring, one of whose ends is fixed to the base and the other of whose ends is able to slide on the bowl of the top, the leaf spring being under tension when the top is closed, and being relaxed or partially relaxed when the top is in the fully open position. This cap is particularly intended for use as a spray head for a spray device.

Abstract: The invention relates to a pouch for a pressurized bottle, made up of a tubular wall closed in its upper part by a welded seam into which a valve is incorporated. According to the invention, the tubular wall is obtained by overlapping and welding together the two lateral edges of a strip, and the tubular wall is closed in its lower part by an essentially round bottom wall. Thus, the tubular wall of the pouch will have a practically circular cross section in a large lower part, this cross section tending towards an elliptical shape as it nears the upper end where it becomes completely flat. The pouch will, at least in a major lower part, occupy practically all the space in the bottle, considerably reducing the dead space in that part.

Abstract: The invention relates to a dispensing head (103) for closing a vessel, mainly a tube or a vial, that comprises an outlet opening (135) and a hinged cap (104) for closing the opening (135) of the dispensing head, wherein the dispensing head (103) and the hinged cap (104) are made of a single piece. According to the invention, the hinged cap (104) is moulded over the dispensing head (103). In order to ensure the anchoring of the cap (104) onto the head (103) even when the materials are not compatible, anchoring means (138, 144) can also be provided.

Abstract: The invention concerns a valve for distributing two fluids contained in a rigid flask by propulsion means, the first fluid having to be contained in a first flexible pouch, and the second fluid in the flask so as to be isolated from the first fluid before the fluid leaves through the valve, the valve comprising an internal part that, when the valve is placed on the flask, is situated inside said flask, and an external part that, when the valve is placed on said flask, is situated outside the latter, a first passage connecting the inside of the first pouch and the space surrounding the external part of the valve, said first passage being provided with first closure means, a second passage connecting the space intended to receive the second fluid and the space surrounding the external part of the valve, said second passage being provided with second closure means.

Abstract: A valve assembly for fluid container under pressure, comprising a valve cup sealingly attachable to an opening of the container, the valve cup having an opening, a valve body of plastic material attached within the cup opening and having a through going axial passage and a sealing surface, a valve piston of plastic material guided within the passage, co-acting with the sealing surface and having a lower portion, spring means co-acting with a valve body which presses the valve piston against the sealing surface, characterized in that a cap is connected to the valve body designed to allow flow or fluid from the exterior of the cap to the interior thereof, a preferably axial projection being formed to the bottom facing upwardly towards the valve body, the bottom projection telescopically co-acting with the lower portion of the valve piston, the lower portion and/or the bottom projection having a spring portion adapted to generate a spring force by which the piston is pressed against the sealing surface.

Abstract: A dispenser packing for viscous or pasty material, comprising a cylindrical container; a piston slidingly movable in said container which divides the interior of the container into an upper chamber for receiving the material and a lower chamber; an expulsion valve for the material at the upper end of the container; a charging valve at the lower end of the container; a hose-shaped or pouch-shaped expulsion element which is connected to the portion of the charging valve which is inside the container and is adapted to be filled with a propellant gas under a pressure, and which abuts, on an outer wall portion, against the piston under a pressure.

Abstract: A valve system for the discharge of a flowable substance from a pressure-tight container by a fluid propellant. The valve has a stem with a central bore for the discharge of the fluid. The stem has a second passage open to the free end of the stem and adapted to be brought into communication with a portion of the air-tight container. To this purpose the stem has a transverse bore which can be connected with the interior of the container through an opening of the housing if the stem is in the opened position. In the closed portion of the stem the transverse bore is closed by an annular seal, preferably by the seal between the dome portion of the valve cup and the valve housing. By this measure the fluid to be discharged can be discharged concurrently with gas or another propellant. This joint discharge can also be used for a mixing up of the fluids.
