1 claim.
This invention relates to pumps and more particularly to a pump intended for use in connection with a container such as a jug or bottle, the pump having a tapered plug-shaped body constituting a closure for the container.
Disinfectants used by dairymen, restaurants, etc., for sterilizing purposes are delivered in glass containers and consist of concentrated acids or other strong liquids and the neck of the container must be kept tightly closed so that the liquid will not lose its strength.
When the liquid is to be used, a small quantity is removed from the container and diluted, and it is one object of the invention to provide a. pump by means of which a small quantity of the liquid may be withdrawn from the container and discharged into a pan or other container in which it is to be diluted for use.
Another object of the invention is to provide a pump so formed that, after a quantity of the liquid has been withdrawn from the container and discharged into a pan, inward suction will be created through the nozzle of the pump and the concentrated liquid prevented from dripping from the nozzle.
Another object of the invention is to provide a combined bottle stopper and pump wherein the tapered body or plug consists of upper and lower sections and an intermediate rubber sheet having portions constituting ilap valves for controlling ow of air and liquid through ports or passages formed through the plug. It will thus be seen that the pump may be easily and cheaply manufactured and its elements very easily assembled.
Another object of the invention is to provide a pump wherein couplings and the discharge spout are formed of glass tubes, thus eliminating metal parts which would become corroded by acid or other strong disinfeotants withdrawn from the container to which the pump is applied.
In the accompanying drawing:
Fig. 1 is a side elevation showing the improved pump applied to a jug or large bottle.
Fig. 2 is a sectional view on an enlarged scale, taken vertically through the improved pump.
Fig. 3 is a sectional view taken horizontally through the pump on the line 3-3 of Fig. 1.
This improved pump has a body I which is tapered toward its lower end and constitutes a vclosure plug for the neck of a, jug or bottle 2 when the pump is applied for use. This plug or body consists of separately formed upper and lower sections 3 and 4 which are formed of rubber and, between these sections is disposed a rubber sheet or strip 5 which is vulcanized to the upper 55 and lower sections and has portions cut to form flap valves 6 and 'I integrally connected vwith the sheet by portions 8 and 9 constituting hinges for the valves. A groove I0 is formed along the plug or body I and constitutes a vent so that air may enter the container 2 as liquid is withdrawn therefrom. This prevents the formation of a vacuum condition within the container above the liquid.
In order that liquid may pass through the plug or 'body I, the upper section 3 is formed with vertically disposed passages II and I2 which are alined with passages I3 and I4 formed in the lower section 4. Lower portions of the passages II and I2 are enlarged to form valve chambers I5 and I6 in which the ap valves operate and the Valve chamber I5 is extended laterally at its inner side to provide a side extension II which surrounds an opening I8 formed in the sheet 5 and communicates with a branch passage I9 extending upwardly at an incline from the lower end of the passage I4. It will thus be seen that the plug is formed with intercommunicating passages through which liquid will flow from the container 2 into a nozzle. This nozzle is formed of glass and has its lower inner end portion tted tightly into the passage I2 through the upper end thereof. A glass coupling sleeve 2I is fitted into the passage II with a portion projecting upwardly therefrom, and to this protruding portion of the coupling is applied a bulb 22 by means of which the pump is operated. A glass coupling sleeve 23 is fitted into the passage I3 with a portion projecting downwardly therefrom and to this coupling is applied the upper end of a exible tube 24 of sufficient length to extend to the bottom of the container.
When the liquid in the container is to be used, the cork or other closure initially applied thereto is removed and the plug I applied and wedged tightly into place with the tube 214 extending to the bottom of the container. After the plug is in place, pressure is applied to the bulb 22 to expel air, and this air will flow through the branch passage I9 and upwardly through the passage I2 into and through the nozzle 20. The bulb is then relieved of pressure and, as it expands, the valve 'l will be held closed by suction and the valve I5 swung upwardly to open position permitting liquid to be withdrawn from the container and into the bulb. Pressure is then again applied to the bulb and since the valve 6 will now lbe held closed, the liquid will be forced through the passages I3 and I4 to raise the valve 'I and flow upwardly and outwardly through the passage i2 and the nozzle. This is repeated until the desired quantity of liquid has been discharged through the nozzle and, at the nal release of the bulb, sufflcient suction will take place through the nozzle, as the valve 'l closes, to draw liquid inwardly from the outer end of the nozzle and prevent liquid from dripping from the nozzle. Therefore, waste of the liquid by drippage will be prevented and also danger of injury or burning by acid dripping from the nozzle will be eliminated.
Having thus described the invention, what is claimed is:
In a pump, a body tapered downwardly for wedging fit within a bottle neck and consisting of upper and lower sections, the upper section being formed with vertical passages having their lower ends enlarged to form pockets'in its-lower facespaced transversely from each other, the pocket of one passage being formed with a side extension projecting toward the other pocket, a nipple`mounted in the lastmentioned pas# sage through the upper end thereof and projecting upwardly therefrom, a bulb carried lby the projecting upper portion of said ni-pple, a discharge nozzle mounted in the other passage through the upper end thereof and projecting upwardly therefrom, the lower section being formed with a vertical passage having its upper end registering with the pocket of the rst passage of the upper section, and a V-shaped passage having one arm registering with the second passage of the upper section and its other arm registering with the side extension of the pocket of the first passage of the upper section, and a sheet of flexible material disposed between said sections in adhering engagement with confronting f aces thereof and cut to form openings registering with the pockets and also form ap valves in the openings operating in the pockets and normally resting upon the lower section in closing relation to passages thereof.
