La presente invention concerne un dispositif pour la distribution d'un produit liquide ou visqueux en vue de son prelevement avec un outil ou par la main d'un utilisateur, comportant un reservoir (1) pour contenir ledit produit et debouchant dans une zone de distribution (2, 7) pour le prelevement dudit produit caracterise en ce que la zone de distribution (2, 7) presente des ouvertures determinees pour empecher le produit de s'exfiltrer en l'absence d'une action de l'utilisateur, et en ce que le reservoir (1) est mis en surpression, ladite surpression etant determinee, en condition d'utilisation, a une valeur inferieure a la pression provoquant le suintement du produit lorsque le dispositif est au repos, ladite pression etant par ailleurs suffisante pour provoquer l'exfiltration du produit sur la zone de distribution (2, 7) lorsque l'utilisateur exerce une action sur ladite zone de distribution (2, 7).

Dispositif pour la distribution d’un produit visqueux ou liquide, notamment un produit de lavage

The invention relates to a device for the distribution of a liquid or viscous product, for dosing onto a tool or the hand of a user, comprising a reservoir (1), to hold said product, opening into a distribution zone (2, 7), for the dosing of said product, characterised in that the distribution zone (2, 7) has fixed openings to prevent the seepage of product in the absence of a user action and whereby the reservoir (1) is pressurised, said pressure being fixed under application conditions at a value below that which causes the weeping of the product when the device is at rest, the pressure being otherwise sufficient to cause the seepage of the product from the distribution zone (2, 7) when the user exerts an action on said distribution zone (2, 7).

Device for distribution of a liquid or viscous product, particularly a cleaning product

PROBLEM TO BE SOLVED: To provide a foam ejection container which suppresses ejection of a content liquid when the foam ejection container is placed in an inverted posture.SOLUTION: In a foam ejection cap 4, there are a gas-liquid mixing chamber 35 which communicates with an ejection hole 4A, a liquid passage R2 which supplies the content liquid in a container body 2 to the gas-liquid mixing chamber 35, and an air passage R1 which supplies air in the container body 2 to the gas-liquid mixing chamber 35. The foam ejection cap 4 includes a liquid valve member 17 which blocks communication between the inside of the container body 2 and the gas-liquid mixing chamber 35 through the liquid passage R2 when the container body 2 is inverted, and an air valve member 45 which blocks communication between the inside of the container body 2 and the gas-liquid mixing chamber 35 through the air passage R1 when the container body 2 is inverted. In the foam ejection cap 4, an outside air introducing hole 28B which introduces outside air into the container body 2 is formed. The foam ejection cap 4 includes an air check valve 15 which stops passing of the air and the content liquid from the inside of the container body 2 to the outside through the outside air introducing hole 28 and permits passing of the air from the outside into the container body 2 through the outside air introducing hole.SELECTED DRAWING: Figure 1

A manually operated demand delivery liquid pump dispensing device, includes: -a container (2) to be filled with a storage (20) of the liquid to be dispensed and with air inside the container, said container comprising a bottom part (6), a top part (5), and a side wall (7) between said bottom part and said top part, and a lid (3) which seals an opening (4) in the top part of the container, usable for filling the container, said lid being provided on the upper side thereof with a shallow basin (15), including, in the centre thereof, a concave dish-shaped cavity (21) and a discharge opening in the region of said dish-shaped cavity of the lid, and with a tube (22) for supplying liquid to said concave dish-shaped cavity from said storage of liquid which may be contained in the container.Said tube has an exterior top section (22a) extending upwards from the bottom of said concave dish-shaped cavity (21), and an interior section (22b) extending downwards from said top section into the storage of the liquid which may be contained in the container.

A liquid dispensing device

A dispenser for a liquid hand lotion has a compressible plastics bottle (10), and a rigid outer shell (20) which surrounds the bottle and has a lower free edge (34) which is normally supported by the bottle at a small distance above a horizontal support surface S. The bottle is screwed to the underside of the outer shell, and a flexible (38) diptube communicates the bottom of the bottle with a dispensing orifice (46) formed in the top of the shell. The product to be dispensed is charged into the container leaving a headspace (50), and for dispensing the user presses down on the outer shell so causing increased air pressure in the headspace to force product through the diptube to the dispensing orifice. After dispensing, resilience of the bottle, assisted by any remanent excess air pressure in the headspace, returns the container to its former condition in preparation for the next dispensing operation.
