Benefits of technology
The invention is a dispenser for semi-solid substances that can be used with one hand. It consists of a hollow body, a piston and a hollow cap. The piston is inside the hollow body and its length is limited to that of a human finger. This allows the user to easily evacuate the entire contents of the dispenser with just their fingers. There is no need for a knife or other implement. The dispenser can be reloaded easily with different substances as needed.
Problems solved by technology
A variety of devices have been created to facilitate dispensing the substance that, as a result of its physical characteristics, can be unwieldly to directly manipulate.
Not only does the '083 device contain several parts, but its utilization of a thread shaft elevator mechanism complicates user operation.
In the typical case of a user inserting a stick of butter into the '083 device, the user will experience a plug of butter being ejected from the device in the general shape of the thread shaft, creating a mess.
Clearly, however, an issue arises where the semi-solid substance is firmly lodged within the device (e.g., cold butter) off the bottom and the force needed to advance it within the cavity is greater than that needed to disengage the dispensing mechanism from the thread shaft.
For semi-solid dispensing devices, the prior art generally discloses devices which require two hands to operate, cannot easily be filled (and re-filled) with product of any texture, or are comprised of many components increasing item cost and reducing overall product reliability.

Embodiment Construction
[0015]FIG. 1 shows a cross sectional view of an exemplary dispenser. A hollow body member 100 contains a piston member 170, forming an interior cavity 120. An open bottom end 130 has a lip portion 140 through which the piston member 170 can be accessed. The interior cavity 120 comprises the space between the piston member surface 175, the interior cavity wall 126, and the hollow body member open top end 110. The interior cavity length 125 is measured longitudinally along the interior cavity wall 126. A friction means 220 secures the hollow cap member 190 onto the hollow body member 100. A vent orifice 230 exists on the hollow cap member 190 to allow air or other gas to escape the interior cavity 120 when the hollow cap member 190 is placed onto the hollow body member 100.
[0016]FIG. 2a shows a cross sectional view of an exemplary dispenser prior to dispensation. A hollow body member 100 as an interior cavity 120 occupied by an “eastern” stick of butter 182. A piston member 170 reside...

A dispenser for dispensing butter, margarine, lubricant, adhesive, or other semi-solid substance. The dispenser comprises a body member and cap member which together enclose the substance when being dispensed. The dispenser further comprises a piston member that is manually actuated to advance the substance out of the dispenser and onto a desired food or surface.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to soft-solid or semi-sold substance dispensers and more particularly a butter dispenser for receiving a stick of butter, storing the stick of butter, and when in use enabling the user to gradually dispense the butter by manually actuating a piston using one or more fingers.Description of Relevant Prior Art[0002]Butter is an ancient and widely used condiment, food ingredient, and food preparation substance. Butter is semi-solid, maintaining its shape when refrigerated and at room temperatures and melting between 32-35° C. (90-95° F.). A variety of devices have been created to facilitate dispensing the substance that, as a result of its physical characteristics, can be unwieldly to directly manipulate.[0003]One such device is depicted in U.S. Pat. No. 4,298,036 entitled “Dispenser for Stick Solids.” Depicted there is a single-use cylindrical dispenser that is adapted to be filled with a semi-liquid s...
