MEDICINE DISPENSER Filed Sept. 27, 1932 2 Sheets-Sheet 2 IL Q A? Inventor Patented Feb. 21, 1933 UNITED STATES earner osrics MEDICINE DISPENSER Application filed September 27, 1932. Serial No. 635,073.
The present invention relates to new and useful improvements in medicine dispensers and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arran ement of parts through the medium of which said dispenser may be enclosed for convenient use in a conventional bottle or other container in which the medicine or other liquid may be sold or kept and wherein a leak-proof closure for said bottle or other container will be provided.
Other objects of the invention are to provide a dispenser of the aforementioned character which will be simple in construction,
strong, durable, efficient and reliable in use,
compact, and which may be manufactured at low cost. I All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein: V
Figure 1 is a view in vertical section through one form of the invention.
Figure 2 is a detail view in vertical section through the cylinder and piston type syringe shown in Figure 1.
Figure 3 is a View in vertical section through a modification of the invention.
Figure 4 is a vertical sectional view through another modification.
Referring now to the drawing in detail, and to Figures 1 and 2 thereof in particular, it will be seen that the reference numeral 1 designates a conventional glass bottle having a reduced, externally threaded neck 2.
The reference numeral 3 designates generally a syringe which includes a barrel 4 in which a piston 5 is slidably operable, said piston 5 being fixed on the lower end portion of a rod 6 which extends slidably through a closure 7 on one end of said barrel 4. A nozzle 8 is provided on the other end of the barrel 4.
On the upper end portion of the piston or container.
.rod 6 are spaced flanges 9 between which a resilient disk'or gasket 10 of suitable material, preferably rubber, is mounted. The resilient disk or gasket 10 is of sufficient diameter for its marginal portion to rest on 755 the upper end of the neck 2 of the bottle 1,
as clearly seen in Figure 1 of the drawing.
A metallic screw cap is designated by the reference numeral 11 and is threaded on the neck E2 of the bottle 1 over the resilient disk or gasket 10. The screw cap 11 is formed to provide a shoulder 12 which is eng'ageable on the resilient disk or gasket 10.
It will thus be seen that the resilient disk or gasket 10 provides means for supporting the syringe 3 in the bottle or other container 1 in a manner to permit the ready removal of said syringe and in addition constitutes sealing means to prevent leakage from said bottle t will be understood the. the bottle or container 1 is to contain the medicine or other liquid to be dispensed. The resilient disk or gasket 10 still further provides means facilitating the manual opera- 7 tion of the piston 5 in the barrel 4, as will be 175 apparent.
In Figure 3 of the drawing, the reference numeral 13 designates a dropper tube of suitable material, preferably glass, having a reduced lower or discharge end portion 14. The other end portion of the tube 13 has formed integrally thereon spaced external flanges 15 between which a resilient disk or gasket 16 of suitable material, preferably rubber, is mounted. The resilient disk or 385 gasket 16 is of a diameter to rest on the upper end of the externally threaded neck 17 of a bottle or other container 18.
' formed to provide a dome 22 which accommodates the collapsible rubber bulb 19.
In this form of the invention, 1t will be seen that the rubber disk or gasket 16, in
addition to providing means for supporting the tube 18 in the bottle or other container 18, also constitutes a seal for preventingleakage from. the bottle when the screw cap 20 is threaded thereon. When it is desired to use the dropper 13, the screw cap 20 is removed and said dropper is lifted out of the bottle or other container. As will be apparent, the bulb 19 provides means for drawing the liquid into the tube 13 and for discharging the liquid from said tube.
In the modification illustruted in Figure l of the drawing, the reference numeral designates n dropper stein having a tapered lower end portion 24, :is usual. Spaced flanges are formed integrally with the upper end portion ot the stem 23 and between snid flanges a resilient di; I or gasket 26 mounted. The resilient disk or gasket 26 functions in a manner similar to the disks or gaskets 10 and 16 tor supporting the drop per stem 23 in :2 bottle or other container and for sealing said bottle or other container, in conjunction with a screw cap. against leuking.
\Vhile the invention is primarily intended for dispensing medicine. it will he understood that said invention inn be used in dispensing any liquids from a container.
it is believed that the many edvuntngcs of n dispenser in accordance with the present invention will be rendi u .der tood, and although the preferred embodiments of the invention as illustrated and (.lescrihed it is to he understood that "further changes in the details ot' construction and in the conihinntion and arrangement ct parts may be resorted to which Wlli'fttll within the scope of the invention as claimed.
\Vhat is claimed is:
In a liquid dispenser. the combination with aliquid holding container including a neck, of a syringe comprising a barrel, a rod extending; slid ably into the barrel, a piston on one end of the rod, a pair of spaced flanges on the other end oi. the rod, a disk mounted. between the flanges and engngenble on the neck for supporting the syringe in suspended position in the container and providing a handle tor operating the syringe, and a cup mounted on the neck and. engaged with the disk for coinpressing;- said disk on the neck.
