Liquid may be drawn from the plunger when an oral syringe is inserted into the cap member.
Description
- This invention relates generally to liquid dispensers and, more particularly, to a liquid dispensing apparatus for use with a liquid medicine bottle for accurately dispensing liquid medicine from the bottle to an oral syringe without turning the container upside down.
- Prescriptions for liquid medicines are frequently contained in bottles and must be drawn into an oral syringe to be dispensed to a patient, particularly in the case of liquid medicine for infants, toddlers, or other young children. The usual method for drawing liquid medicine into an oral syringe is to invert the bottle, puncture a seal in the top of the bottle or otherwise insert the tip of the syringe into a valve, and then draw a prescribed amount of liquid into the syringe. Upon removal of the desired amount of liquid medicine, the syringe may be withdrawn from the bottle and the bottle turned right side up for storage. Then the medicine may be delivered to the patient.
- Bottles must be inverted before drawing out the liquid to avoid drawing a volume of air into the syringe or to dispense the final amount of liquid remaining in a bottle. Drawing air into the syringe is undesirable as it makes it difficult to determine whether the proper amount of liquid has been drawn in. The obvious disadvantage of failing to draw out all of the liquid in the container is that all of the medicine should be taken for the medical ailment and because the medicine may be quite expensive.
- Various devices have been proposed in the art for drawing liquid from a bottle, such as those proposed in U.S. Pat. Nos. 4,230,112, 4,493,348, and 4,128,098. Although assumably effective for their intended purposes, these devices have not entirely eliminated the need to invert the bottle to avoid withdrawing air into an oral syringe or to ensure that all of the medicine is withdrawn from the bottle.
- Therefore, it would be desirable to have a liquid dispenser apparatus for use with a bottle of liquid that enables the liquid to be drawn into an oral syringe without inverting the bottle. Further, it would be desirable to have a liquid dispenser cap that enables liquid to be drawn into the syringe without withdrawing any air. In addition, it would be desirable to have a liquid dispenser cap that enables all of the liquid in a bottle to be withdrawn from the bottle without inverting the bottle.
- Therefore, a liquid dispenser device according to the present invention includes a cap member having a tubular configuration complementary to a configuration of a mouth of a bottle for a friction-fit insertion in the mouth thereof. Thus, the cap member may be selectively inserted and removed from the mouth of the bottle as desired, such as between doses of medicine. The device includes an elongate tube having an upper end connected to a lower opening defined by the cap member and a lower end that may be positioned adjacent a bottom wall of a bottle when the cap member is inserted into the bottle. Further, a plunger is positioned within an axial bore of the cap member between upper and lower openings thereof, the plunger being movable between a retracted configuration that closes the tube upper end and an extended configuration extending into the tube. The plunger also defines an aperture through which liquid from the tube may flow into the plunger when the plunger is at the extended configuration. When inserted into the mouth of a bottle, a traditional child resistant cap may be placed on the mouth of the bottle.
- Therefore, a general object of this invention is to provide a liquid dispensing apparatus for enabling liquid to be drawn from a bottle into an oral syringe without inverting the bottle and syringe.
- Another object of this invention is to provide a liquid dispensing apparatus, as aforesaid, in which liquid may be drawn from the bottle without drawing air into the syringe.
- Still another object of this invention is to provide a liquid dispensing apparatus, as aforesaid, that enables substantially all of the liquid in a bottle to be withdrawn by an oral syringe without inverting the bottle.
- Yet another object of this invention is to provide a liquid dispensing apparatus, as aforesaid, that may be conveniently attached to and removed from the mouth of a bottle.
- A further object of this invention is to provide a liquid dispensing apparatus, as aforesaid, that is economical to manufacture.
- Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

FIG. 5 b is an isolated view on an enlarged scale taken from a portion ofFIG. 5 a illustrating the plunger in an extended configuration and the oral syringe in a withdrawal configuration; and -
FIG. 6 is an exploded view of the liquid dispensing apparatus as inFIG. 1 . - A
liquid dispenser apparatus 10 according to a preferred embodiment of the present invention will now be described with reference toFIGS. 1 through 6 of the accompanying drawings. - The
liquid dispenser apparatus 10 includes acap member 12 having a generally tubular configuration complementary to a configuration of a mouth of abottle 7, such as a bottle containing a liquid medicament. More particularly, thecap member 12 may include anouter wall 14 having a tubular or cylindrical configuration for slidably bearing against an inner surface of the mouth of thebottle 7 when thecap member 12 is inserted therein. Theouter wall 14 presents a diameter slightly smaller than a diameter of the inner surface of the mouth of thebottle 7 such that theouter wall 14 fits therein in a relatively tight friction-fit relationship. In this preferred embodiment, it should be understood that a conventional child-resistant cap (not shown) may be mounted atop thebottle 7 for safety reasons. Alternatively, thecap member 12 may include a threaded configuration (not shown) that can be coupled to thebottle 7 in a more traditional manner. Thecap member 12 further includes aninner wall 16 connected to theouter wall 14 and defining opposed upper 18 and lower 20 openings. Theinner wall 16 also defines anaxial bore 22 connecting the openings. - The
cap member 12 includes atop plate 24 mounted atop the outer 14 and inner 16 walls, the top plate having a diameter slightly larger than the diameter of theouter wall 14 as well being larger than a diameter of the inner surface of the mouth of the bottle 7 (FIGS. 2 b and 6). In use, thetop plate 24 acts as a stop to prevent over-insertion of thecap member 12 into the mouth of abottle 7 and also aids a user in removing thecap member 12 therefrom. Thetop plate 24 defines an upper opening that registers with theupper opening 18 defined by theinner wall 16 for receiving a nozzle 9 b of an oral syringe 9 a therein, as will be described in more detail later. - The liquid dispensing
apparatus 10 further includes anelongate tube 26 having opposed upper 28 and lower 30 open ends. Theupper end 28 of the tube is connected to thelower opening 20 of the cap member 12 (FIGS. 3 a and 6). When thecap member 12 is positioned on abottle 7, thelower end 30 of thetube 26 may be situated on or adjacent to a bottom wall 8 of abottle 7. - Further, the
liquid dispenser apparatus 10 includes aplunger 32 situated in theaxial bore 22 of thecap member 12 between the upper 18 and lower 20 openings of the cap member 12 (FIGS. 3 b and 6). Theplunger 32 includes anupper portion 34 having a generally cylindrical outer configuration sized for slidable movement within theaxial bore 22 between a retracted configuration (FIG. 3 b) and an extended configuration (FIGS. 4 b and 5 b), these configurations to be described in more details below. In addition, theupper portion 34 includes a generally conical or funnel-shaped inner configuration capable of receiving an oral syringe nozzle 9 b. Theplunger 32 also includes alower portion 36 extending downwardly from theupper portion 34 and having a closed bottom, the lower portion being capable of extending into thetube 26 at the extended configuration. Thelower portion 36 defines at least oneaperture 38 for receiving liquid from thetube 26 into theupper portion 34 when theplunger 32 is moved to the extended configuration (FIGS. 4 b and 5 b). - At the retracted configuration, the
plunger 32 closes the upper opening of thetube 26 such that liquid from thebottle 7 is not communicated into theplunger 32 or inadvertently spilled (FIG. 3 b). At the extended configuration, thelower portion 36 of theplunger 32 is extended through the upperopen end 28 of thetube 26 such that liquid in thetube 26 may enter thelower portion 36 through theaperture 38. Liquid in theplunger 32 may then be drawn up into the nozzle 9 b of the oral syringe 9 a.FIGS. 5 a and 5 b illustrate the oral syringe 9 a in a configuration in which liquid is being drawn up through thetube 26,plunger 32, and syringe nozzle 9 b. It is understood that insertion of the oral syringe 9 a into thecap member 12 causes theplunger 32 to be moved from the retracted configuration (FIG. 3 b) to the extended configuration (FIG. 4 b). - The
liquid dispenser apparatus 10 further includes a means for normally biasing theplunger 32 toward the retracted configuration. More particularly, the biasing means includes adiaphragm 40 positioned atop thecap member 12 surrounding theupper opening 18 thereof. Thediaphragm 40 is attached to theplunger 32 such that it is stretched downward when theplunger 32 is moved from the retracted configuration to the extended configuration, such as when an oral syringe nozzle 9 b is inserted into thecap member 12 and pushed down upon theplunger 32. Preferably, thediaphragm 40 is constructed of a resilient flexible material such as rubber although other materials having elastic properties would also be suitable. When the oral syringe 9 a is removed, thediaphragm 40 returns to its normal configuration allowing theplunger 32 to return to the retracted configuration. - In use, the
liquid dispenser apparatus 10 may be used to draw liquid, such as liquid medicine, from a bottle without inverting the bottle. Specifically, thecap member 12 of theapparatus 10 may be inserted into the mouth of abottle 7 in a friction fit relationship. When securely inserted, thelower end 30 of thetube 26 will be positioned on or very near the bottom wall 8 of thebottle 7 such that most if not all of the liquid may be drawn out (FIG. 3 a). The nozzle 9 b of an oral syringe 9 a may be inserted through theupper opening 18 of thecap member 12 and into theupper portion 34 of the plunger 32 (FIG. 4 b). Pressure by a user upon the oral syringe 9 a will cause theplunger 32 to move slidably within the cap member bore 22 from the retracted configuration (FIG. 4 b) to the extended configuration in which thelower portion 36 of theplunger 32 extends into the tube 26 (FIG. 4 b). - As shown in
FIG. 5 b, a user may then operate the oral syringe 9 a to suction liquid through thetube 26 into theplunger 32 and into the oral syringe 9 a. While liquid may need to at first be primed into the tube (and thus air is drawn into the oral syringe 9 a, this is then subsequently unnecessary. In other words, when the oral syringe 9 a is withdrawn following initial priming, the closed end of the plunger lower end 30 seals thetube 26 in a vacuum relationship such that thetube 26 remains full of liquid ready for the next dose/draw. Accordingly, thebottle 7 never needs to be inverted so as to prevent air from being drawn into the oral syringe 9 a. - It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
