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 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 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: A spray discharge cap for a sprayer having a valve, comprising: a spray release top attachment including a retainer ring and an actuation element which is hinged to said retainer ring, an outlet tube having an outlet opening and an inlet opening that is connected to said valve, a piston element movably disposed in said outlet tube which is in a position closing said outlet opening if said actuation element is not depressed, and which is movable inside said outlet tube via a dog mechanism, wherein said dog mechanism interacts with said actuation element in such a way that if said actuation element is depressed said piston element is in a position releasing said outlet opening.

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 tiltable valve for discharging foam and other media from a pressurized vessel includes a valve disk for connection to the vessel, and a valve body having a holder opening that is placed in an opening in the valve disk and a sealing surface at a side facing away from the valve disk. The tiltable valve further includes a valve element disposed in the holder opening which has a tubular portion with a sealing flange at one end and at least one inlet opening in the wall, such that in a closed position of the valve, the sealing flange bears on the sealing surface and blocks an entry of the medium requiring discharge in the inlet opening and, in a tilted position of the valve element, the sealing flange and the sealing surface are spaced from each other while forming a gap and the medium requiring discharge is allowed to exit through the gap and the inlet opening.

Abstract: A The invention discloses an assembly consisting of a head (1, 1′, 200) and an overcap (30, 30′, 30″, 300), the head having a cylindrical neck provided with a helical screw thread (21), the overcap having a cylindrical skirt (31) provided with a thread (36) matching the neck thread (21). The overcap carries an axial plate (33) radially flexible and circumferentially rigid. The neck base (10) is provided with at least an opening stop (12), and at least a closure stop (11), of lesser height. When the overcap (30) is screwed on the head for mounting the assembly, the free end of the axial plate is urged into contact with a first wall (14) of the opening stop (12) and the axial plate whereof the free end is urged by a centrifugal motion, is elastically deformed then, folds down towards the neck in a space between the opening (12) and closure (11) stops, its displacement being thereby restricted.
