PCT No. PCT/DE95/00547 Sec. 371 Date Nov. 1, 1996 Sec. 102(e) Date Nov. 1, 1996 PCT Filed Apr. 24, 1995 PCT Pub. No. WO95/29759 PCT Pub. Date Nov. 9, 1995The invention relates to a device for generating and metering foam, especially foamed soap. To prevent further dispensing of drips of residual foam in a foam outlet channel after the quantity required has been supplied, the device is constructed in such a way that the underpressure subsisting on the return stroke of a piston in an air chamber is effective in the foam outlet channel and sucks residual foam back. |
