发明名称 Liquid soap dispenser with built-in pump
摘要 A liquid soap dispenser suitable for installation on a mounting surface comprises a socket including an upper part having an upper edge, a tubular piece, the socket and the tubular piece being mountable on the mounting surface. A tubular pump including an actuating rod is housed in the tubular piece, the tubular pump and actuating rod defining a conduit for the liquid soap and being axially reciprocable through a pumping stroke between a highest and a lowest position. The actuating rod extends through an annular gap and a soap dispensing nozzle having a cap fits over the upper socket part and has a lower edge facing the upper socket part, the nozzle cap and the upper socket part defining in all stroke positions an annular gap concentrically surrounding the annular gap through which the actuating rod extends. The nozzle cap defines an annular recess facing the upper edge of the upper socket part, the upper edge and the lower edge extending substantially in the same plane when the actuating rod is in the highest position, and the external diameter of the upper socket part being slightly smaller than the diameter of annular recess at least along a length corresponding to the length of the stroke of the actuating rod whereby the upper socket part may be slid into the annular recess.
