Abstract:
The present invention to a pump-action nozzle arrangement (100) adapted to be fitted to an opening of a container and enable a liquid or air/gas to be dispensed from the interior of said container during use. The nozzle arrangements (100) have a body which defines: (i) an internal chamber (102) ; (ii) an inlet (110) through which fluid can be drawn into said chamber (102); (iii) an outlet orifice (112) ; and (iv) an internal passageway (106) that connects said chamber to said outlet orifice. The nozzle arrangement (100) also further comprises a one-way inlet valve (108a) adapted to only permit fluid to be drawn into said internal chamber (107) through the inlet when the pressure within the chamber falls below the external pressure, an actuator and a one-way precompression valve (105) disposed in the internal passageway (106) that is configured to only permit fluid to flow along said internal passageway (106) when the pressure within the chamber equals or exceeds a predetermined minimum threshold pressure. The body of nozzle arrangement (100) is configured such that the internal volume of the chamber (107) is reduced when said actuator is operated, thereby causing fluid stored in the chamber (107) to be ejected along said internal passageway (106) to the outlet office, and increased when said actuator is released, thereby causing fluid to be drawn into the chamber (107) through the inlet (110). The precompression valve (105) comprises a valve member integrally formed with a portion of the body that defines said internal passageway (106), said valve member being configured to assume a resiliently biased configuration in which said internal passageway (106) is closed when the pressure within the chamber (107) is below the predetermined minimum threshold pressure and to be displaced from said resiliently biased configuration to define an opening through which fluid can flow along the internal passageway (106) when the pressure within the chamber (107) equals or exceeds the predetermined minimum threshold pressure.
Abstract:
A hand actuated multiple-container trigger sprayer includes a spray head assembly (22) removably connected to a plurality of fluid containers (24a, 24b). The sprayer head assembly (22) has an outer housing (30), a nozzle (40) attached to the housing (30), a pump mechanism (34) enclosed within the housing (30), and tubing (60a, 60b) fluidly connecting each of the plurality of fluid containers (24a, 24b) with the pump mechanism (34) in the housing (30). A trigger or lever (42) actuates the pump mechanism (34) to draw fluid through the tubing (60a, 60b) from each of the plurality of fluid containers (24a, 24b) and to discharge the fluid through the nozzle (40). A metering device (36) is located between the fluid containers (24a, 24b) and the pump mechanism (34) and is accessible externally from the housing (30) to selectively control the amount of fluid drawn from the containers (24a, 24b). The metering device (36) includes flow paths to the pump mechanism (34) for each of the fluid containers (24a, 24b). The diameter and length of at least one of the flow paths can be controlled to selectively control the amount of fluid drawn from the fluid containers (24a, 24b).
Abstract:
The invention relates to an apparatus for dispensing predetermined amounts of viscous product. A drawback of the prior art devices is the inability to quickly and accurately measure quantities dispensed from a collapsible tube. The present invention provides an improved apparatus which has a conduit (17) which is telescopingly received within a cap (14). The cap and the conduit define an expandable dosing chamber which expands to a predetermined maximum volume when product is introduced into the chamber through the conduit. A check valve (19) prevents back flow of product through the conduit. Collapsing the chamber (Fig. 7) from its maximum volume to a minimum volume dispenses the product from the dosing chamber.

Abstract:
Dispositif de distribution de produit fluide comportant un réservoir (100), une pompe (50) définissant une chambre de pompe (56), un premier piston (51 ) coulissant de manière étanche entre une position de non-distribution et une position de distribution, une tête de pulvérisation (10) comportant un corps (11 ) définissant un canal d'expulsion (12) et pourvu d'un orifice de distribution (1 ), un obturateur (40) disposé dans ledit canal d'expulsion (12) en amont de l'orifice de distribution (1 ), ledit obturateur (40) étant déplaçable entre une position d'obturation et une position de non-obturation, et un second piston (57) coopérant avec ledit obturateur (40) pour le déplacer vers sa position de non-obturation, dans lequel, en position de distribution du premier piston (51 ), ladite chambre de pompe (56) est reliée au réservoir (100) pour égaliser les pressions après chaque actionnement.
Abstract:
The invention concerns a fluid product dispensing pump designed to be associated with a fluid product reservoir (60), said pump comprising a pump body (10), a pump chamber (20), and at least one first piston (72) sliding in said pump chamber (20) to dispense the fluid product through a dispensing orifice (45), said pump including an air priming channel (100) connecting said pump chamber (20) to said reservoir (60) when the pump is primed.
Abstract:
1) Dispositif pour la distribution de produits liquides sans reprise d'air à partir d'un réservoir (R) muni d'un fond mobile (F), d'un conduit d'échappement (C) et d'un poussoir coopérant avec un piston et un ressort de rappel (S), caractérisé en ce qu'il, comprend une douille (1) d'étanchéité et de dosage supportant un pointeau d'obturation (2) déplaçable en translation dans ûn canal d'évacuation (12) ménagé sur ladite douille en étant raccordé par une biellette d'entraînement (3) à une tige axiale (4) de guidage susceptible de coulisser dans le conduit d'échappement (C) du réservoir communiquant avec ledit canal, par appui sur ladite douille (1) et compression dudit ressort (S).
