Definitions

  • the further conduit provides a distinct channel between the inlet orifice and the discharge orifice, which is separate from the other two conduits. This further conduit facilitates venting of excess air from the storage chamber via the inlet orifice.
  • an inlet of the further conduit may be adjacent to the apex of the inverted U-shape.
  • the base of the trigger sprayer is fixed to the bottle in a Iiquid-tight manner.
  • the reservoir in the container and the storage chamber in the bottle become fluidly coupled, when the container, the trigger sprayer, and the bottle are attached.
  • FIG. 1 schematically shows an exploded side view of an embodiment of a sprayer system 1 .
  • the sprayer system 1 comprises a detergent container 10, a trigger sprayer
  • the container 10 is attachable to the trigger sprayer 40 on one side thereof. This side is associated with a container attachment region 2.
  • the bottle 60 attachable to the trigger sprayer 40 on another side thereof. This side is associated with a bottle attachment region 6 that is essentially opposite to the container attachment region 2.
  • FIGs 2a and 2b schematically show cross-sectional front views of the sprayer system 1 from figure 1.
  • Figure 2a shows an open configuration, wherein the sprayer system 1 is refillable with solvent liquid.
  • Figure 2b shows an operational configuration, in which the container 10, trigger sprayer 40, and bottle 60 are interconnected.
  • the base 44 defines a liquid guiding surface 51 inside the inlet orifice 46.
  • This guide surface 51 includes an inverted U-shape, which curves around the pump mechanism
  • solvent liquid e.g. water supplied in this manner via the inlet orifice 46, will be conveyed through the internal conduits 52 and the further orifice 54 downstream into the storage chamber 62.
  • the further internal conduit 53 is adapted to facilitate venting of air from inside the storage chamber 62, during filling.
  • the container 10 In the coupled state, the container 10 is fixed to the base 44, and a liquid-tight coupling between the outlet and inlet orifices 26, 46 is established.
  • the closed valve member 30 still prevents liquid detergent 16 in the reservoir 15 from entering the inlet orifice 46.
  • the valve member 30 By transitioning the valve member 30 from the closed to the open position, the reservoir 15 and the storage chamber 62 become fluidly connected via the outlet and inlet orifices 26, 46, the internal conduits 52, the further orifice 54, and the bottle orifice 64.
  • liquid detergent 16 in the reservoir 15 may then freely flow downwards by gravitational pull into the storage chamber 62, and mix with the solvent liquid to obtain the aqueous liquid mixture 70.
  • the connector 18 includes a toroidal portion 20, which forms a predominantly cylindrical structure that surrounds the outlet orifice 26 and the valve member 30, and which protrudes outwards from the container body 12 along the axis A1.
  • the user may move the container 10 with the toroidal portion 20 along the nominal axis A1 towards the inlet orifice 46, to establish an engaged state.
  • the connector 18 includes a male screw thread 22 around the toroidal portion 20.
  • the connector 48 on the trigger sprayer 40 includes a female screw thread, which extends along an inwards surface inside the inlet orifice 46.
  • the screw threads 22, 48 cooperate to allow rotation of the container body 12 relative to the trigger sprayer 40 over a combined angle ⁇ about the axis A1 .
  • the combined angle is at least 270°.
  • Opening the valve member 30 may comprise further rotating the container body 12 relative to the base 44 over an actuation angle ⁇ 2 about the axis A1 , to transition the valve member 30 from the closed position to the open position.

Abstract

L'invention concerne un pulvérisateur à gâchette (40) pour générer un spray de liquide aqueux. Le pulvérisateur à gâchette comprend une buse pour faire sortir le spray, un mécanisme de pompe (41) pour transporter le liquide (70) depuis une chambre de stockage (62) vers la buse, une poignée pour actionner le mécanisme de pompe et une base (44) recevant le mécanisme de pompe. La base comprend un orifice d'entrée (46), qui s'ouvre dans une partie de paroi externe (45) de la base et qui est orientée vers le haut pendant l'utilisation, un orifice de sortie (54) qui se trouve sensiblement à l'opposé de la partie de paroi externe et qui est conçu pour être accouplé à un autre orifice (64) d'une bouteille (60) pourvue de la chambre de stockage et un conduit interne (52a,52b), qui s'étend à travers la base entre les orifices d'entrée et de sortie pour réaliser un passage étanche aux liquides non obstrué entre l'orifice d'entrée et la chambre de stockage lorsque le pulvérisateur à gâchette est relié à la bouteille.
