Abstract

A dispenser for dispensing an alcohol-glycerine disinfecting gel or liquid for use by doctors and nurses. The dispenser consists of a main housing which mounts a pumping mechanism for pumping out an alcohol-glycerine disinfecting gel from a replaceable, disposable supply-cartridge releasably mounted in the main housing. Since the main housing is small enough to fit within a person'"'"'s hand, the doctor or nurse may dispense the contents of an alcohol-glycerine disinfecting gel simply by squeezing the two parts together. The dispensing of the gel is applied directly onto the fingers of the same hand that has squeezed the main housing to have caused such dispensing to occur. Owing to the small size of the main housing, the dispenser of the invention may be worn on-the-person, such as by the waist-belt.

Claims

1. In a dispenser for dispensing small amounts of a solution comprising a main housing and a discharge outlet, a supply of a solution in said main housing to be dispensed, means for pumping out the solution from through said discharge outlet, wherein the improvement comprises:

said main housing being operable by one hand for pumping out said solution;

securing means operatively associated with said main housing for securing said main housing to a person, whereby the dispenser may be worn on-the-person for transport with the person;

said supply comprising disinfecting liquid or gel for disinfecting the hands;

said discharge outlet having a discharge opening that dispenses said disinfecting liquid or gel such that the dispensed disinfecting liquid or gel is not directed toward the person when said securing means mounts said main housing to a person for dispensing the disinfecting liquid or gel;

said discharge outlet dispensing said disinfecting liquid or gel for disinfecting the hands directly onto said one hand that operates said means for pumping out said solution while said securing means mounts said main housing to the person.

2. The dispenser for dispensing small amounts of a solution according to claim 1, wherein said supply comprises a removable supply cartridge;

said main housing comprising a hollow interior for mounting said removable supply cartridge therein;

said means for pumping comprising a plunger means mounted in said hollow interior above said removable supply cartridge and having an internal passageway through which the disinfecting solution travels from said removable supply cartridge to said discharge outlet;

tube means having a first end in fluid communication with said internal passageway and a second end inserted in said removable supply cartridge;

said plunger means being slidably mounted in said hollow interior for at least slidable movement toward said removable supply cartridge.

3. The dispenser for dispensing small amounts of a solution according to claim 2, wherein said plunger means is mounted in said hollow interior for abutting contact against said removable supply cartridge;

and further comprising biassing means for biassing said removable supply cartridge, and, therefore, said plunger means, upwardly;

said housing having stop means for preventing said plunger means from escaping said hollow interior when said biassing means moves said plunger means upwardly within said housing.

4. The dispenser for dispensing small amounts of a solution according to claim 2, wherein said main housing comprises a front wall and a rear wall, said front wall comprising an upper cutout section;

said plunger means comprising an upper spout-section;

said upper spout-section extending forwardly through said cutout-section of said front wall;

said discharge outlet being formed in said upper spout-section extending forwardly through said cutout-section of said front wall.

5. The dispenser for dispensing small amounts of a solution according to claim 1, wherein said supply comprises a removable supply cartridge.

6. The dispenser for dispensing small amounts of a solution according to claim 5, wherein said removable supply cartridge comprises a contracting, supply bag of disinfecting solution.

7. The dispenser for dispensing small amounts of a solution according to claim 1, wherein said main housing comprising a hollow interior for storing said supply of disinfecting solution;

said housing being accordion-like for allowing compression thereof in order to squeeze out said disinfecting solution;

said means for pumping comprising a plurality of compressible accordion-sections constituting said main housing whereby when said compressible accordion-sections are squeezed by a hand and compressed, said disinfecting solution is forced out through said discharge outlet.

8. The dispenser for dispensing small amounts of a solution according to claim 7, wherein said discharge outlet is formed in the top-most section of said plurality of compressible accordion-sections.

9. The dispenser for dispensing small amounts of a solution according to claim 8, wherein said securing means comprises a first section secured to the upper surface of said top-most section, and a second section extending at an angle thereto in a direction along said plurality of compressible accordion-sections, and clip means mounted to said second section for clipping said main housing to a garment of a person.

10. The dispenser for dispensing small amounts of a solution according to claim 7, wherein each of said plurality of compressible accordion-sections a lower and an upper frustoconical section, said lower frustoconical section having a truncated lower surface, and said upper frustoconical surface having a truncated upper surface, adjoining sections of said plurality of compressible accordion-sections being connected together at the respective said upper and lower truncated surfaces thereof.

11. A method of dispensing a small amount of disinfecting solution by means of a small dispenser having a discharge outlet and a supply of said solution, comprising:

(a) removably attaching the small dispenser to a person;

(b) dispensing a small quantity of said solution into a hand of the person to whom said dispenser has been attached while said small dispenser is still attached to the person;

(c) said step (b) comprising dispensing a small qunatity using one hand, and squeezing said dispenser with said one hand to cause a small amount of said solution to exit through said discharge outlet onto said one hand, said solution exiting through said discharge during said step of dispensing.

12. The method of dispensing a small amount of disinfecting solution according to claim 11, wherein said step (c) comprises squeezing a compressible, accordion-shaped main housing in which is stored the disinfecting solution, to forcibly squeeze the solution out through the discharge outlet.

13. The method of dispensing a small amount of alcohol-disinfecting solution according to claim 11, wherein said step (a) comprises securing the dispenser to the waist-belt of the person.

14. In a dispenser for dispensing small amounts of a solution comprising a main housing and a discharge outlet, and a supply of solution to be dispensed through said discharge outlet, wherein improvement comprises:

said main housing being of an overall size so as to be useable by one hand;

securing means operatively associated with said main housing for securing said main housing to a person, whereby the dispenser may be worn on-the-person for transport with the person;

said discharge outlet dispensing said solution directly onto said one hand that operates said pumping means for pumping out said solution while said securing means secures said main housing to a person.

15. The dispenser for dispensing small amounts of a solution according to claim 14, wherein said main housing comprises a plurality of compressible accordion-sections whereby when said compressible accordion-sections are squeezed by a hand and compressed, said disinfecting solution is forced out through said discharge outlet.
