Abstract: In a packaging container (1a) provided with a distribution valve (7), a chamber is provided enclosing the starting components of a system (9) for the anaerobic fermentation of sugars using yeasts, which produce the carbon gas forming said propulsive product. The chamber is composed either of a flexible, gas-tight, hermetically closed pocket (8) or of a small rigid reservoir, which is normally closed by a valve calibrated to open only when the pressure which is established in said reservoir exceeds by a given value the pressure reigning in the interior space of the packing container.

Abstract: The present invention relates to a nozzle for dispensing a product, in particular a foaming product, contained in a pressurized container. The nozzle comprises three elements: an element (6) for fixation onto the container; a dispensing element (5); and a lateral element (7) for coupling the first two elements. The coupling element (7) has an elasticity such that its height varies between the operating position and the position of repose by a value equal to the sum of the distance between the upper edge of the emergent stem in the position of repose and the projection of the hole when the nozzle is in the position of repose, and the distance corresponding to the course of driving in of the emergent stem between its position of repose and the position of complete opening of the valve. The emergent stem of the valve, in the position of repose, is completely outside the hole.

Abstract: A container for nail polish includes a stopper (1) to which a brush (4) is affixed, and a bottle (2). The container has an elongated shape, similar to that of a fountain pen, and the bottle (2) is divided into two compartments (5, 6) by a valve (7), in particular a ball valve. The valve (7) is open when the stopper (1) of the container is in a lowered position with respect to the bottle (2).

Abstract: A flexible gas-tight, hermetically sealed pouch (11), in which a likewise closed cartridge (8) filled with a propellant in the liquid phase is disposed, is introduced into the outer envelope (1) of a container (1a), and the container (1a), which includes a valve (7) for distributing fluid (13) contained in it or introduced via the valve (7) is plugged. The cartridge (8) used has a wall capable of degrading at least partially from simple contact with the propellant, until the cartridge opens, within a period of time at least equal to that necessary to assure the packaging and closure of the container (1a ). The propellant then spreads within the pouch (11), changing at least in part to the gaseous phase, at a pressure suitable to assure the dispensing of the fluid (13). By the judicious choice of the characteristics (type, thickness) of the degradable zone of the cartridge (8), heating or other more complicated or expensive means proposed heretofore for putting the container under pressure are avoided.

Abstract: Products having a viscous or pasty consistency, or those dispensed as foams from a container (1) provided with a pushbutton (13) the actuation of which causes the ejection of a dose of product, are never, in practice, completely evacuated from the ejection conduit (14) made in a movable portion (9) bearing the pushbutton (13) and adapted to the outlet of the container (1). Hence they often threaten to escape from this conduit (14) and soil the container (1). To overcome this disadvantage, the invention proposes that the conduit (14) discharge into a chamber (40) defined by a fixed portion (10) attached to the container (1) and with the movable portion (9) comprising a dispensing cap (8); the chamber (40) opens to the outside via an opening (38), and the movable portion (9) includes a needle (27) capable of closing this opening (38) in the position of repose of the pushbutton (13) and of freeing it upon actuation of the pushbutton.

Abstract: The device (1) includes an applicator brush (4) including a rod (5) provided with applicator means (A) such as bristles (6). The rod (5) is carried by a cap (7) intended to close the neck, and this cap is integrally joined to a sheath (9) capable of surrounding the rod (5). The rod (5) is mounted displaceably in the sheath (9) with respect to the cap (7), and at its end remote from the cap, the sheath (9) includes a restriction (11), through which the applicator means (A) of the brush can pass. The rod (5) of the brush includes an enlargement (12) arranged to come into contact with the restriction (11) by gravity, when the brush (4) is oriented downward, so as to retain the rod and close the restriction. Toward the cap, the sheath (9) includes at least one opening (14, 15) allowing liquid to enter the sheath when the bottle, closed by the cap, is inverted, and a free space (16) exists between the inside surface of the sheath and the outer surface of the rod to form a reservoir for the liquid.

Abstract: A container is provided with a dispensing device including a bent delivery tube directable in relation to a valve-actuating element which is displaceable in relation to a mounting skirt for fixing the device on the container; dispensing of the product from the containers by way of a duct having a first portion arranged in the delivery tube and a second portion in the actuating element which includes an oblique surface in relation to the axis of the skirt; a delivery tube includes a swiveling mount for moving it about an axis normal to the oblique surface and an abutment means for bearing on the oblique surface so that in one position the delivery tube is substantially parallel to the axis of the skirt.

Abstract: Substantially greaseless cosmetic stick, particularly for applying eye shadow, comprises a carrier of compacted powder made of materials softer than calcium carbonate having a particle size between 1 and 20 microns, while its other constituents consist of powders having a particle size not greater than 25 microns.

Abstract: Improved hair dryer has inner and outer ducts connected at one end to a centrifugal fan and at the other end to a hood. The fan sucks air through the inner duct and blows it toward said hood through the outer duct. A grille for supporting long hair is positioned in the inner duct so that air drawn toward the fan is drawn through any long hair on said grille.

Abstract: Atomizer for liquids is mounted on a compressible container for the liquid so as to define an atomizing chamber in the neck of the container, which has an outlet nozzle and is connected through a depending tube to the lower part of the container and through a short duct to its upper part. The container is also connected to the open air through inlets controlled by non-return valves preventing the escape of fluid therethrough. When the container is compressed liquid flows into the atomization chamber through the tube, and air flows into it through the duct, so that a spray is dispensed through the nozzle. When the container is permitted to expand air is sucked in through the air inlets, which are larger in section than the nozzle. In one embodiment filters are provided to filter air drawn in through the air inlets.

Abstract: Tube having flexible walls and a neck separated from the remainder of the tube by a transverse wall having an opening therein closed by a plug adapted to be expelled from the orifice when the tube is squeezed. The plug is cup-shaped and made of a rubbery material so as to increase the permissible manufacturing tolerances.

Abstract: Dispensing cap for pressurized containers comprises a wall adapted to snap onto the top of the container, a movable member defining a duct adapted to seat on the outlet tube of the container valve and through which its contents may be ejected, and a separable actuating member which projects through the wall to actuate the movable member.
