Abstract
LIQUID DISPENSING DEVICE INCLUDING A CONTAINER, SAFETY CLOSURE AND SYRINGE TYPE DISPENSER
Abstract of the Disclosure Described is a liquid dispensing device including a container, safety closure and syringe type dispenser. The syringe dispenser is utilized to draw product from the container and disperse it, the stem of the plunger including indicia to permit accurate measurement of the liquid being dispensed. The dispenser makes it possible to make accurate measurement of an opague liquid that would coat the surface of the barrel of the dispenser obscurring the liquid level.

Description
6~4 Background of the Invention There is a need for syringe type dropper assemblies for use with viscus and/or opaque liquid preparationsl particu-larly pharmaceutical preparations for administration to infants or children. U.S. Patent 3,572,337 issued March 23, 1971, discloses a syringe for oral administration of medicaments but this syringe is not designed to remain in a liquid container nor does it have calibrations marked on the plunger for meas-uring the amount of medicament dispensed. UOS. Patent 3,101,751 issued August 27, 1963, discloses a liquid dropper assembly which has incorporated therein metering means for predetermining the number of drops which can be drawn into the dropper regardless of the pressure exerted upon the squeeze bulb. Of course, a conventional dropper assembly would not be suitable for dispensing medicaments to infants and children since such assemblies are not precise enough and any indices on the dropper or sides of the container would be obscured or difficult to read when dispensing an opaque medicament.
For pediatric use where dosage relates to the weight of the infant or child, it is important that the medicament can be easily and accurately dispensed. It is also advantageous that such dispensing containers minimize the possibility of acci-dental spillage of the contents or the unauthorized removal of product by in~ants and small chilclren. An example of such a safety type closure is disclosed in U.S. Patent 3,558,022, issued June 2~, 1971.
Sun~nary of the Inven~ion -Described is a liquid dispensing device including a container, a safety closure and a syringe type dispenser.
The syringe type dispenser is retained within a cap adapted for attachment to a container, the plunger of the syringe dispenser being utilized to draw the product from the container and also force it out. By placing measurement indica on the stem of the plunger, it is posslble to make an accurate measurement of the product being removed from the container particularly if the product is an opaque liquid that might : ' ;
6~4 coat the dropper surface obscuring the liquid level in-side the dropper. With medicaments intended for pediatric use, such as liquid aspirin for example and where the dosage relates to the weight of the child, precise dispensing of thç medicament is i~lportant. With the dispensing device of the present invention the calibrations or indices on the stem of the plunger enable measurements to be -taken without removal of the dropper portion from the product. Another advantage is that the dropper portion is a part of the closure and consequently is always retained with the container and the productO The device is particularly suitable as a dis-penser for viscus and opaque liquids such as food and li~uid medications which are adminis-~ered to infants.
Broadly speaking, therefore, the present invention provides a liquid dispensing device including a syringe-type dispenser and comprising: ~a) a container having an open- -ing, (b) a safety closure dlsposed within the opening in the container, the closure including a passageway therethrough -~
communicating with the inside of the container and means for sealing the passageway when the syringe dispenser is removed therefrom to thereby prevent spillage or accidental removal of product within the container, (c) a syringe dispenser dis-posed within the opening in -the container and extending through the passageway in the safety closure and into the container and comprising a barrel extending through the opening in a cap and positioned therein, the cap being engageable with -the container to seal the opening therein, the barrel includincJ
a concentric collar at the upper end thereof the collar being of a diameter greater than the barrel, an annular -flange ex-tending from the collar and fitting within the cap to retain the syrinye dispenser within the cap, the collar extending upwardly through the opening in the cap, @~ ~
(d) a plunger movable within the barrel for drawing liquid into and dispensing liquid from the barrel~' and (e) a stem affixed to and extending from the plunger through the barrel, the stem including indicia for measure-ment of liquid within the barrel~

Detailed Description of the Invenkion Figure 1 illustrates a liquid dispensing device 10 including a container 11, a safety closure 20, and a dispens-ing device 35. A product 12 is stored withln the container : , 11. The closure 20 is spill resistant and minimizes unauthor-ized removal of product b~ children. It is inserted within the neck portion 13 of the container 11 in fluid tight engage- -ment therewith and with the finish 14 of the container 11.
The closure 20 is described fully in U.S. Patent

The safety closure 20 includes a con-tai,ner engaging body portion 21 having a passageway 22 therethrough and which is adapted to conform in fluid ,.
tiyht engagement with the opening or neck portion 13 of the container 11. As lllustrated, the body portion 21 of~the closure 20 includes a plurality of spaced vertical rib.s 23 formed in the wall 24 of the body portion 21. The ribs 23 assist in creating an effective friction fit with the.neck 13 of the container 11 when the closure 20 i..s ins,erted within the neck 13. The annular flange 25 ex-tending from the wall 24 of the body portion 21 of the clos,ure 20 rests on the finish 14 of the container 11 when inserted within the neck 13 thereby preventing leakage of any of the contents 12 of the container 11. As with the ribs~23~ the flange 25 is preferred since it seats tightly against the finish 14 of the containe:r thereby minimizing the possibility of any leakage, Extending from the body portion 21 of the closure 20 is a depending portion 26 which is rectilinear in configura-tion and angular so that one wall 27 of the dependiny por-' ~ tion 26 e~tends beyond the l'ngth o~ the opposing wall portion2~ and forms a passageway ~ which extends through the body portion 21 and into the container 11 when the closure 20 is positioned in place.

In use, the valve 29 is forced open by the syringe dispenser 35 as illus-trative in figure 1. When the syringe dispenser 35 is withdrawn, the valve ~ is biased into a closed position by a helical spring 30 mounted on the body portion 21 of the closure 20 as described in Patent 3,558,022.
