ATTORNEY Patented Oct. 24, 1933 PATENT OFFICE LIQUID DISPENSER Bernard Kaplan, Fairfax, Calif;

Application January 3,

2 Claims.

The present invention relates to improvements in liquid dispensers, and has among its objects the provision of a container having a valve-controlled spout leading therefrom, the valve being operated by means of a-flexible diaphragm forming part of the container. Upon flexing the diaphragm for discharging liquid the valve is automatically opened for allowing the liquid to flow from the spout, and upon releasing the diaphragm the valve is again closed.

It is particularly proposed to use the dispenser for injecting liquid adjacent to the roots of plants or weeds in lawns and the like, the liquid being of such character as to destroy or kill the weeds. In this connection I provide the spout with a tapering pointed element adapted for thrusting into the ground near the root of the weed, while the valve is closed, and as the diaphragm is moved the valve is opened and the discharge of the fluid effected.

The invention, of course, is not to be limited to this particular field, since the principle may be readily applied to oil cans, or in fact to any dispenser in which a valve-controlled spout is desired.

It is further proposed to provide adispenser that is simple in construction, durable and efiicient for the purpose intended.

Other objects will appear as the specification proceeds and the novel features will be particularly set forth in the claims hereto appended.

For a better understanding of my invention reference should be had to the accompanying drawing, forming part of this application, in which:

Figure 1 is a side elevation with parts in section; and

Figure 2 illustrates the dispenser in inverted position with the valve opened.

In carrying my invention into practice, I provide a container 1 having a spout 2 extending therefrom and communicatingwith the interior of the container at 3. The spout preferably is secured to a cap 4, the latter being removably fastened to the mouth 5 of the container by threads 6 or other suitable fastening means. The bottom of the container is formed with the usual snap diaphragm '7 adapted for forcing liquid from the spout when the container is inverted and the diaphragm flexed.

The means for controlling the flow of fluid from the spout consists of a valve 8 adapted for seating upon the conical seat 9 fastened at the end of the spout. A pointed element 10 extends from the body of the valve and is adapted to be thrust into the ground adjacent to the roots of weeds or the like so as to inject fluid to the latter upon opening the valve, or if the container is being used as an oil can, the valve would serve as a closure over the end of the spout.

1933. Serial No. 649,780

In Figure 1 I show a stem 11 extending axially through the spout, and having the upper end thereof secured to the valve at 12, while the opposite end rests against the inner surface of the diaphragm. Upon flexing the diaphragm inwardly of the container, the valve is raised from its seat and at the same time a small quantity of fluid is forced from the spout. The valve is returned to its seat upon releasing the diaphragm by means of a spring 13 encircling the stem and bearing at one end against a spider 14 mounted transversely over the opening in the cap 4, the other end of the spring butting against an adjustable nut 15 threaded on the stem. The lower end ofthe stem projects through an opening 16 in a stirrup guide 17, the latter having its ends turned outwardly at 18 and anchored to the cap 4. The lower end of the stem is provided with adjustable nuts thereon that may be adjusted so as to vary the amount of fluid dispensed during each flexing of the diaphragm. The nuts are indicated at 18 in Figure 1.

Having thus described the different parts of my invention, the operation thereof may be readily understood. The user flexes the diaphragm in much the same manner as in using a conventional oil can for effecting discharge of fluid, and upon releasing the diaphragm the valve is automatically closed. The pointed element 10 protects the valve as the spout is introduced into the ground.

Although I have shown only the preferred form of my invention it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit thereof.

Having thus described my invention, what I I desire to secure by Letters Patent is:

l. A dispenser comprising a container, a spout extending therefrom, a valve mounted to seat upon the end of the spout and conforming in exterior diameter therewith, and forming an uninterrupted continuation of the spout when seated, the tip of the valve being fashioned with a relatively high conical portion tapered to a point, and means for opening and closing the valve upon its seat.

2. A dispenser comprising a container, a spout extending therefrom, a valve mounted to seat upon the end of the spout and including a substantially cylindrical portion conforming in exterior diameter with the spout, and forming an uninterrupted continuation of the spout when seated, the tip of the valve above the cylindrical portion being tapered to a point, and means for opening and closing the valve upon its seat.
