A hand held, free standing, bottom dispensing dispenser, generally made of plastic, for the dispensing of thick liquids such as lotions, shampoos, and processed foodstuff, having a resiliently walled reservoir that sits atop a stand that offers fulcrum for a mechanical linkage. The linkage has a top portion engaged to the reservoir side wall allowing the user\s hand to grasp and manipulate the linkage while grasping and manipulating the reservoir, and a bottom portion coupled to dispensing valve disposed and adapted to open and close a discharge element affixed to an outlet in the bottom end of the reservoir. Thus, when hand pressure is applied to the linkage top portion at the same time the reservoir is squeezed and the motion transmitted by the linkage to the dispensing valve opens the latter to dispense a portion of the content. When pressure is relieved, the resilient reservoir side wall rebounds back to its initial shape and, the reservoir side wall being engaged to the linkage moves the latter back to its initial position. Thus while causing the dispensing valve to gradually close, the reservoir side wall outward movement induces in the reservoir an air flow that draws the fluid in the discharge element in therewith. The dispenser content is always located in the lower part of the reservoir near its aperture, ready to be dispensed, therefore making possible the dispensing of virtually all the content.

A bottom dispensing free standing hand held dispenser for viscid liquids, such as lotions and shampoos, comprising: a manually squeezable reservoir generally made of a resilient plastic to preclude deformation of its original shape after manipulation, and having a side wall converging upwardly to a curved top portion, and a bottom portion ending in an aperture for the passage of liquid therethrough; a discharge element for said reservoir having a top and bottom portions, said top portion having annular attachment means for securing said discharge element to said reservoir aperture in transverse arrangement thereacross in a liquid tight seal, said bottom portion terminating in a downwardly and forewardly projecting tubing, terminating in an outlet aperture; a dispensing valve disposed and adapted to open and close said discharge element, normally in a first closed position and movable away to a second dispensing position; a stand for said reservoir to allow free standing of the dispenser, having walls aligned with and supporting said reservoir side wall, said stand having anchoring means to secure said reservoir to the stand, said stand also incorporating an opening for accommodating said discharge element outlet aperture; a mechanical linkage disposed and adapted to transmit movement of said reservoir side wall to said dispensing valve, said mechanical linkage having pivot means mounted on said stand and comprising a top portion engaged with said reservoir side wall and a bottom portion coupled with said dispensing valve, said mechanical linkage is so disposed to constrain said dispensing valve to synchronously move with said reservoir side wall, said dispensing valve being movable to said second dispensing position when said reservoir side wall is moved inward due to hand pressure acting on said reservoir side wall and said mechanical linkage top portion simultaneously, and to said first closed position urged by the rebounding movement of said reservoir side wall after relief of hand pressure, so that said dispensing valve closes only when said reservoir is back to its original shape.
