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.

Claims (4)
- Zusammenschiebbare Pumpkammer (40) zur Verwendung in einer von Hand zu betätigenden Flüssigkeitsspender-Pumpvorrichtung (20), mit einer ringförmigen, gefalteten Seitenwand, die einen inneren Volumenbereich der Pumpkammer festlegt und die eine Struktur aufweist, die so ausgebildet ist, daß sie sich bei Betätigung der Pumpvorrichtung in einem vorbestimmten Muster zusammenfaltet, dadurch gekennzeichnet, daß das vorbestimmit Zusammenfaltungs-Muster zu einer anfangs relativ kleinen Volumenänderung des inneren Volumenbereiches für eine vorgegebene Hublänge führt, gefolgt von einer vergrößerten Volumenänderung des inneren Volumenbereiches für eine vorgegebene Hublänge.
- Zusammenschiebbare Pumpkammer (40) gemäß Anspruch 1, dadurch gekennzeichnet, daß die gefaltete ringförmige Seitenwand eine Dicke aufweist und daß Änderungen in der Dicke der gefalteten ringförmigen Seitenwand einen Bereich der Struktur ausbilden, der das Zusammenfalten der Seitenwand im vorbestimmten Muster verursacht, wenn die Pumpvorrichtung betätigt wird.
- Zusammenschiebbare Pumpkammer (40) entsprechend einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß die Seitenwand einen Faltungswinkel aufweist und Veränderungen des Faltungswinkels der gefalteten ringförmigen Seitenwand einen Bereich der Struktur ausbilden, der das Zusammenfalten der Seitenwand im vorbestimmten Muster verursacht, wenn die Pumpvorrichtung betätigt wird.
- Von Hand zu betätigende Spender-Pumpvorrichtung (20) zum Pumpen einer Flüssigkeit aus einem Vorratsbehälter und zur Abgabe der Flüssigkeit durch eine Auslaßöffnung, mit(a) einem Gehäuse (26) zur versiegelten Anbringung der Spender-Pumpvorrichtung auf dem Vorratsbehälter, welches Gehäuse einen Abschnitt eines Flüssigkeitskanals (38,42,48,40) umfaßt, der den Flüssigkeitszulauf vom Vorratsbehälter stromabwärts zur Auslaßöffnung ermöglicht;(b) einem innerhalb des Flüssigkeitskanals angeordneten Einlaßventil (34,35), welches Einlaßventil zum Sperren des Flüssigkeitsstroms während Phasen mit positivem Druck stromabwärts geschlossen ist und während Phasen mit negativem Druck stromabwärts geöffnet ist;(c) ein Innerhalb des Flüssigkeitskanals angeordnetes Auslaßventil (30,32), welches Auslaßventil zum Durchlaß eines Flüssigkeitsstroms während Phasen mit positivem Druck stromaufwärts geöffnet ist und während Phasen mit negativem Druck stromaufwärts geschlossen ist; und(d) einer zusammenschiebbaren Pumpkammer, die einen Abschnitt des Flüssigkeitskanals stromabwärts vom Einlaßventil und stromaufwärts vom Auslaßventil festlegt, welche zusammenschiebbare Pumpkammer eine zusammenfaltbare Seitenwand aufweist, die einen Bereich der Pumpkammer festlegt und welche eine Struktur aufweist, die so ausgebildet ist, daß sie sich bei Betätigung der Pumpvorrichtung in einem vorbestimmten Muster zusammenfaltet, dadurch gekennzeichnet, daß die Seitenwand einen inneren Volumenbereich der Pumpkammer festlegt und eine Struktur aufweist, die so ausgebildet ist, daß sie sich bei Betätigung der Pumpvorrichtung in einem vorbestimmten Muster zusammenfaltet, welches vorbestimmte Faltungsmuster zu einer anfangs relativ kleinen Volumenänderung des inneren Volumenbereiches für eine vorgegebene Hublänge führt, gefolgt von einer vergrößerten Volumenänderung des inneren Volumenbereiches pro vorgegebene Hublänge.
