Abstract (en)
[origin: US2009302064A1] A fluid dispensing pump that can be manufactured from as few as two parts: a stationary pump base (200) provided with an inlet passageway (201), and an integral pump top (300) provided with a fluid-tight attachment to the pump base and including a generally rigid core (310) and a self-restoring elastomeric layer (320). The generally rigid core (310) has a base attachment portion (311) and a dispensing valve core (315). The elastomeric layer (320) includes a resilient self-restoring pump wall (323) and a dispensing valve membrane (325). Upon assembly of the pump base and the pump top, a fully functional dispensing pump (100) is created with an inlet passageway (101), a one-way inlet valve (102), a self-restoring resilient pump cavity of variable volume (103) and a one-way dispensing valve (105). The one-way dispensing valve is preferably self-closing. The integral pump top (300) may have a rigid or semi-rigid actuator portion (314) bound to or imbedded into the resilient self-restoring pump wall (323). The dispensing pump of the present invention may have a valved venting passage for those applications that require it and may have a secure lock-in mechanism for leakage prevention during storage or transportation.
