System and method for liquid measuring dispenser

A dispensing device for a fluid container, the dispensing device comprising:

• (a) a container cap associated with the container, said container cap having at least one aperture;
• (b) a switching nozzle having a closing state and an opening state, in said closing state said switching nozzle hermetically sealing said at least one aperture;
• (c) a securing mechanism adapted for preventing undesired opening of said at least one aperture;
• (d) a dispensing compartment attached to said switching nozzle and having an annular portion such that opening said at least one aperture allowing fluid flowing from the container to said dispensing compartment, said dispensing compartment having limited volume for receiving the fluid;
• (e) a setting mechanism adapted for:
• (I) determining said limited volume of said dispensing compartment;
• and
• (II) securing said limited volume from undesired variation;
• (f) a cover mechanism associated with said setting mechanism for enclosing of said limited volume;
• (g) said annular portion has a plurality of first structural deviations and a plurality of quantity markings associated with the plurality of the first structural deviations;
• and
• (h) a maximal mating torque is exerted in mating said at least one setting bump with a certain first structural deviation of said annular portion, and a minimal de-mating torque has to be exerted for cancelling an executed mating, said maximal mating torque is substantially less than said minimal de-mating torque, thereby providing at least a child-proof safety from undesired variation of the determined limited volume.

A method for a person setting a volumetric dose on a fluid bottle, the method comprising:

• (a) providing a fluid bottle having:
• (i) a fluid flowing mechanism adapted for controlled flowing of fluid from the bottle;
• (ii) a dispensing compartment adapted for receiving a limited volumetric dose from said fluid bottle through said fluid flowing mechanism;
• and
• (iii) said dispensing compartment includes an annular portion for receiving the fluid, and a setting mechanism, said annular portion has a plurality of clefts and a plurality of quantity markings associated with the clefts, said setting mechanism encompassing said annular portion and having at least one setting bump bulging proximate to said annular portion;
• (b) setting the dispensing compartment for receiving a limited volumetric dose of the fluid;
• (c) securing said setting mechanism;
• and
• (d) inserting said at least one setting bump into at least one cleft, thus exposing at least one of said markings through an aperture in said setting mechanism, and preventing undesired variation of said limited volumetric dose.
