Patent Images
1. A self contained viscous liquid dispenser, comprising:
- a housing;
an internal liquid reservoir defined by said housing;
a manually operated dispensing pump mechanism disposed in liquid communication with said reservoir and having a delivery end disposed for delivering metered doses of viscous liquid from said reservoir upon actuation thereof by a user;
a mounting mechanism formed integrally in said housing, said mounting mechanism detachably connectable with complimentary mounting structure on a wall surface such that upon mounting said housing, a back side of said housing is generally flush with the wall surface; and
a vent mechanism disposed in an upper wall of said housing, said vent mechanism further comprising a vent passage and a movable plug member resiliently disposed in said vent passage, said plug member sealing an orifice into said vent passage in an at-rest position and movable to unseal said orifice and vent said reservoir upon a sufficient vacuum being established in said reservoir upon actuation of said pump mechanism.

Abstract
A viscous liquid dispenser includes a housing that defines an internal liquid reservoir. A dispensing pump mechanism is disposed in communication with the reservoir and has a delivery end extending from the housing for manual operation by a user. A mounting mechanism is configured as an integral component of the housing and provides the dispenser with the ability to be detachably connected to complimentary mounting structure on a wall surface. A unique vent is disposed in the top wall of the housing to vent the reservoir upon actuation of the pump mechanism.
