Definitions

  • the present invention relates to manually compressible pump chambers for use with consumer product liquid dispensing pump devices.
  • the lower housing 26 includes an inlet passage 42 with a inner conical inlet valve seat 35 which cooperates with the inlet valve member 34 to form the inlet valve 34 and 35. Furthermore, the lower housing 26 includes three equally spaced retaining tabs 36 which retain the inlet valve member 34 during operation of the pump device 20, as discussed hereinafter. Alternatively, a ball valve (not seen) could be utilized.
  • the lower housing 26 also includes a vent opening 37, three equally spaced actuation lugs 44, a cooperating lug 45, and three equally spaced anti-rotation lugs 46. Friction fit onto the inlet passage 42 of the lower housing 26 is a diptube 38 which extends down into the container 22.
  • the outlet end of the collapsible pump chamber 40 is attached by fiction fit to the inner cylindrical wall 52 of the upper housing 24.
  • the outlet end of the collapsible pump chamber 40 includes an elongate channel 66 which has an integral outlet valve seat 32 which cooperates with the outlet valve member 30 to form the outlet valve 30 and 32.
  • the elongate channel 66 also includes an integral outlet opening 68.
  • the liquid dispensing pump 20 is in the closed position.
  • the outlet opening 68 of the bellows 40 is misaligned with the outlet passage 48; providing a fluid tight shipping seal.
  • the shipping seal includes several functional elements; e.g., the outlet opening 68 and the cylindrical wall 52 which can be moved relative thereto to seal the outlet opening 68. Therefore, the liquid passage which flows through the diptube 38, inlet passage 42 of the lower housing 26, the bellows 40, and the outlet passage 48 of the upper housing 24 is sealed closed; thereby providing a shipping seal.

  1. Chambre de pompe pliable (40) utilisable dans un dispositif à pompe de distribution de liquide à actionnement manuel (20), comprenant:
    une paroi latérale annulaire plissée définissant une partie volumétrique interne de la chambre de pompe et ayant une structure adaptée pour être affaissée suivant une configuration prédéterminée lorsque le dispositif à pompe est actionné, caractérisée en ce que la configuration prédéterminée d'affaissement résulte en une modification de volume initialement relativement faible de la partie de volume interne par longueur de course donnée, suivie par une modification de volume accrue de la partie de volume interne par longueur de course donnée.
  2. Chambre de pompe pliable (40) selon la revendication 1, caractérisée en ce que la paroi latérale annulaire plissée a une épaisseur et des variations d'épaisseur de la paroi latérale annulaire plissée constituent une partie de la structure adaptée pour provoquer l'affaissement de la paroi latérale suivant la configuration prédéterminée lorsque le dispositif à pompe est actionné.
  3. Chambre de pompe pliable (40) selon l'une quelconque des revendications 1 ou 2, caractérisée en ce que la paroi latérale a un angle de plissement et des variations de l'angle de plissement de la paroi latérale annulaire plissée constituent une partie de la structure adaptée pour provoquer l'affaissement de la paroi latérale suivant la configuration prédéterminée lorsque le dispositif à pompe est actionné.

    (b) une soupape d'entrée (34, 35) située dans le passage de liquide, la soupape d'entrée étant fermée pour empêcher un écoulement de liquide à travers celui-ci, pendant les périodes où la pression en aval est positive, et étant ouverte pendant les périodes où la pression en aval est négative,
    (c) une soupape de sortie (30, 32) située dans le passage de liquide, la soupape de sortie étant ouverte pour permettre un écoulement de liquide à travers celui-ci, pendant les périodes où la pression en amont est positive, et étant fermée pendant les périodes où la pression amont est négative, et
    (d) une chambre de pompe pliable définissant une partie du passage de liquide en aval de la soupape d'entrée et en amont de la soupape de sortie, la chambre de pompe pliable ayant une paroi latérale pliable définissant une partie de la chambre de pompe, la paroi latérale pliable ayant une structure adaptée pour être affaissée suivant une configuration prédéterminée lorsque le dispositif à pompe est actionné,
    caractérisé en ce que la paroi latérale définit une partie volumétrique interne de la chambre de pompe et possède une structure adaptée pour être affaissée suivant une configuration prédéterminée lorsque le dispositif à pompe est actionné, la configuration prédéterminée d'affaissement résultant en une modification de volume initialement relativement faible de la partie volumétrique interne par longueur de course donnée, suivie par une modification de volume accrue de la partie volumétrique interne par longueur de course donnée.
