Abstract
The dispensing device includes a hollow tube having an open upper end and an open lower end, as well as a horizontal bar disposed between the walls of the hollow tube adjacent to the open lower end. A disc is movably positioned within the hollow tube, the disc having a central aperture defined therein. A string or other flexible member has one end secured to the disc. The other end of the string is drawn downward in the tube, looped around the horizontal bar, then drawn upward through the central aperture in the disc and out the open upper end of the tube. A semi-solid medication is loaded in the tube between the disc and the open lower end of the tube. When the string is pulled out of the upper end of the tube, the disc is drawn downward, dispensing the medication.
Claims8
A dispensing device for dispensing a pharmaceutical preparation, comprising:
- a hollow tube, the hollow tube consisting of an outer peripheral wall, inner side walls, an open upper end, an open lower end, and an external annular flange extending around the open upper end of the tube, the open lower end defining a port, wherein the tube has a uniform internal diameter;
- a horizontal bar extending transversely between opposing inner side walls at the lower end of the tube adjacent the port;
- a disc movably disposed within the tube, the disc having a central aperture defined therein;
- and
- a string having a first end extending out of the open upper end of the tube and a second end secured to the disc, the string being looped around the horizontal bar and extending through the central aperture in the disc so that when the first end of the string is pulled, the disc pushes pharmaceutical preparation though the lower end of the tube to dispense the preparation.
A dispensing device for applying a semi-solid medicament to a body cavity, the device comprising:
- a hollow, transparent tube, the hollow transparent tube consisting of an outer peripheral wall, inner side walls, an open upper end and an open lower end, the open lower end defining a port, the hollow transparent tube having a uniform internal diameter, graduated indicia on the outer peripheral wall corresponding to internal volume of the tube measured from the port toward the upper end, and an external annular flange extending around the open upper end of the tube;
- a horizontal bar extending transversely between opposing inner side walls at the lower end of the tube adjacent the port;
- a disc movably disposed within the tube, the disc having a central aperture defined therein;
- a string having a first end extending out of the open upper end of the tube and a second end secured to the disc, the string being looped around the horizontal bar and extending through the central aperture in the disc so that when the first end of the string is pulled, the disc pushes pharmaceutical preparation though the lower end of the tube to dispense the preparation;
- and
- a pull attached to the first end of the string, the pull having a diameter greater than the internal diameter of the tube to keep the first end of the string outside the tube.
