Self-contained viscous liquid dispenser

A self contained viscous liquid dispenser, comprising:

• a housing;
• an internal liquid reservoir defined by said housing, said reservoir defining a volume capacity for said dispenser;
• 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;
• said housing and associated pump mechanism having a combined packaging weight in grams;
• wherein a ratio of said packaging weight in grams to said volume capacity in liters does not exceed about 120:1;
• wherein said recess has dimensions so that the complimentary wall mounting structure fits entirely within said recess such that upon mounting said dispenser on the wall surface, said back side of said dispenser is flush against the wall surface;
• wherein said mounting mechanism comprises a recess formed integrally in a back side of said housing, said recess further comprising side walls having engaging structures defined thereon for engagement with complimentary structure provided on the wall mounting structure;
• and
• wherein at least one dimension of said recess is less than the complimentary dimension for the corresponding mating component of the wall mounting structure such that upon mounting said housing onto the wall mounting structure, said recess is caused to flex to accommodate the oversized component of the wall mounting structure.
