Mixing cup with extrusion plunger
A device for mixing and dispensing a flowable material or mixture of materials, the device comprising a cup having a bottom with a protrusion having an opening; a plunger having a dispensing port and air vent holes; a plug; a nozzle; and, a lid. The plug can be associated with and plug the cup protrusion opening when the cup is being filled or mixed, or the plug can be associated with the plunger port to seal off the air vent holes when material is dispensed from the device. Also disclosed is a method of mixing and dispensing a flowable material.
1. A device for mixing and dispensing a flowable material comprising:
a mixing cup having a protrusion extending from the cup, said protrusion including an aperture;
a plunger comprising at least one port having an opening adapted to allow air from the internal portion of the cup to flow outward when said plunger is depressed, and a sealing member adapted to engage the sidewall of the cup;
one or more plugs adapted to removably engage the cup protrusion or the plunger port; and
a hollow nozzle, the nozzle having a proximal end having internal threads adapted to engage with the plunger port.
2. The device of claim 1 , wherein said mixing cup comprises an interior bottom surface that extends beyond the terminal portions of said protrusion, or said plug when secured to said protrusion whereby the mixing cup can be positioned approximately flush with a flat surface.
3. The device of claim 1 , wherein said sealing member comprises an upper sealing member portion adapted to engage the mixing cup sidewall, and a lower sealing member portion adapted to engage the mixing cup sidewall.
4. The device of claim 1 , wherein said one or more plugs comprises a plug having an outer cylindrical portion having an exterior wall including threads, an interior wall including threads, and a central plugging member, the plug adapted to removably engage either the mixing cup protrusion or the plunger port.
5. The device of claim 1 , and therefore comprising a cap adapted to removably fit over the distal end of the nozzle, or the cup protrusions, or the port.
6. The device of claim 1 , and further comprising a lid adapted to removably engage the mixing cup rim.
7. A system for mixing and dispensing a flowable material comprising:
a rotation mixer having a basket for holding in relative position a mixing cup containing material for mixing under asymmetric rotation, wherein said mixing cup comprises a protrusion extending from the cup;
a plunger having at least one port and at least one sealing member adapted to engage the sidewall of the cup, wherein said port includes an opening adapted to allow air from the internal portion of the cup to flow outward when said plunger is depressed, said wherein said protrusion includes an aperture adapted to allow material from the internal portion of the cup to flow outward when said plunger is depressed; and
one or more plugs adapted to removably engage the cup protrusion or the plunger port, wherein said one or more plugs comprises a plug having an outer cylindrical portion having an exterior wall including threads, an interior wall including threads, and a central plugging member, the plug adapted to removably engage either the mixing cup protrusion or the plunger port.
8. The system of claim 7 , wherein said mixing cup comprises an interior bottom surface that extends beyond the terminal portions of said protrusion, or said plug when secured to said protrusion whereby the mixing cup can be positioned approximately flush with a flat surface.
9. The system of claim 7 , wherein said sealing member comprises an upper sealing member portion adapted to engage the mixing cup sidewall, and a lower sealing member portion adapted to engage the mixing cup sidewall.
10. The system of claim 7 , and further comprising a hollow nozzle, the nozzle having a proximal end having internal threads adapted to engage with the plunger port.
11. The system of claim 10 , and further comprising a cap adapted to removably fit over the distal end of the nozzle, or the cup protrusion, or the port.
12. The system of claim 7 , and further comprising a lid adapted to removably engage the mixing cup rim.
13. A system for mixing and dispensing a flowable material or mixture of materials, the device comprising:
a mixing cup having a protrusion extending from the cup, said protrusion including an aperture;
a plunger adapted to fit at least partially within the mixing cup, the plunger comprising:
a central port associated with the plunger bottom and having a threaded aperture defined therein,
at least one air vent hole defined in the port;
at least one sealing member adapted to engage the sidewall of the cup;
one or more plugs adapted to removably engage the cup protrusion or the plunger port; and
wherein said mixing cup comprises an interior bottom surface that extends beyond the terminal portions of said protrusion, or said plug when secured to said protrusion whereby the mixing cup can be positioned approximately flush with a flat surface.
14. The device of claim 13 , wherein said sealing member comprises an upper sealing member portion adapted to engage the mixing cup sidewall, and a lower sealing member portion adapted to engage the mixing cup sidewall.
15. The device of claim 13 , wherein said one or more plugs comprises a plug having an outer cylindrical portion having an exterior wall including threads, an interior wall including threads, and a central plugging member, the plug adapted to removably engage either the mixing cup protrusion or the plunger port.
16. The device of claim 13 , and further comprising a hollow nozzle, the nozzle having a proximal end having internal threads adapted to engage with the plunger port.
17. The device of claim 16 , and further comprising a cap adapted to removably fit over the distal end of the nozzle.
18. The device of claim 13 , and further comprising a lid adapted to removably engage the mixing cup rim.
