Improved Dosing System

Abstract

The present invention refers to an improved dispensing system for liquid dispensing in the form of drops, comprising: a cap; a dosage unit having a skirt showing a protrusion or edge at its lower end; and a container having a shoulder surface located at the inner part of the shoulder, wherein the shoulder surface holds the dosage unit through interfering with said protrusion or edge of the insert thus avoiding that the dosage unit can be removed from the container. While opening the improved dispensing system according to the present invention, a ring attached to the cap body breaks in sections, preventing said ring to be relocated in the cap and, thus, avoiding that the dosage unit can be reused for filling a different substance.

DETAILED DESCRIPTION OF THE INVENTION

[0051] The present invention consists in a dispensing system (500) for liquid dispensing in the form of drops which comprises a cap (100), a dosage unit (200) having a skirt (205) showing a protrusion or edge (207) at its lower end and a container (300) having a shoulder surface (307) located at the inner part of the shoulder (308), wherein the shoulder surface (307) holds the dosage unit (200) through the interference of said protrusion or edge (207) with the dosage unit (200).

[0052] The explosion view of the elements of the dispensing system (500) of the invention can be seen in FIG. 2.

[0053] As can be seen in FIG. 3, the cap (100) is provided with an inner ring (107), a ring projection (108) of the inner ring (107), a ring (103) attached to the cap body (101) through a plurality of binding points (109) radially located on ring (103), fins (104) located in the inner part of the ring (103) and slots (102) perpendicularly located on the ring (103).

[0054] As can be observed in FIG. 4, the dosage unit (200) comprises a dosage portion (201) located on the upper segment of the dosage unit (200), a protrusion (202) located at the lower part of the dosage portion (201), an adjustment surface (203) located between the dosage portion (201) and a skirt (205) of the dosage unit (200).

[0055] The dosage unit (200) further comprises a retaining ring (204), an adjustment aperture (206), a protrusion or edge (207) located at the lower part of the skirt (205), a channel (208) and a positioning portion (209) located at the lower part of the dosage unit (200) immediately below the protrusion or edge (207).

[0056] According to FIG. 5, the container (300) is provided with a thread (305) located on the outer part or the container opening (302), a container retaining ring (306) (shown in FIG. 7), located at the inner part of the container opening (302), ratchets (304) located at the outer part of the container neck (309), a surface (307) (Shown in FIG. 1 and FIG. 7), located at the inner part of container (300) and radially extending over the shoulder (308).

[0057] In the aperture operation of dispensing system (500), the fins (104) of the cap (100) face the ratchets (304) of the container (300) when the cap (100) rotates, causing ring (103) to detach from the cap body (101) along the annular cut (105) and the bindings between the semi-rings forming the ring break, due to shearing of the binding points (109) and finally, the ring (103) is divided in sections according to the slots (102), see FIG. 6).

[0058] During the dosage unit (200) assembling onto the container (300) as seen in FIG. 7, once the container (300) has been filled with the desired liquid, the dosage unit (200) is fixedly/inseparably embedded in container (300) when it slides through the container opening (302) and along the container neck (309) which is possible by the adjustment aperture (206) contraction until the protrusion or edge (207) of the dosage unit (200) exceeds surface (307) of container (300) thus obtaining a safe assembly of the dosage unit (200) in the container (300) as the protrusion or edge (207) remains secured against the container neck (309).

[0059] According to FIG. 8, the dosage unit (200) is fitted in the cap (100) through the connection between the ring projection (108) of the cap, within the channel (208) located beneath the protrusion (202) in the dosage unit (200).

[0060] Assembling the cap (100), the dosage unit (200) and the container (300) can be carried out through initially pre-assembling the dosage unit (200) into the cap (100), then locate this pre-assembled unit over the neck (309) of the container (300) and closing using the thread (305) and the inner thread (106).

[0061] During the aperture of the dispenser (500), the ring (103) definitively breaks into sections, preventing said ring (103) to be relocated in the cap (100) as can be seen in FIG. 9 of the invention.

[0062] The container (300) may further have an inscription or warning label (303) located at the outer lower part of the container opening (302) such that when ring (103) is released or detached by removing the cap for the first time, said warning (303) becomes visible to the eyes of the consumer, advising him/her that said container has been opened. See FIG. 9.

[0063] Other embodiments of the present invention evident to those skilled in the art after the description of the present invention has been read and the invention practiced, are understood to be included within the scope of protection of the present invention. The present description is illustrative and not limitative of the scope and spirit of the invention, which is only limited by the following claims.
