  • Patent number: 4240564
    Abstract: A portable hand held soap leaf dispenser includes a housing adapted to support a stack of soap leaves therein. The housing has an opening adjacent one end through which soap leaves are individually dispensed. An ejector member is slidably supported in the housing for fore and aft movement between a forward ejecting position and a rearward retracted position. A biasing mechanism urges the ejector member and adjacent soap leaf into engagement whereby the adjacent soap leaf is dispensed through the opening in response to movement of the ejector member from the retracted position to the ejecting position therefor. The soap leaves may be supported on a platform biased toward the ejector member by the biasing mechanism. A plurality of wedges on the underside of the ejector member retentively engage a soap leaf in response to forward movement of the ejector member and freely slide over the soap leaves in response to rearward movement of the ejector member.
