3 Claims.

Aillustrated a practicalembodiment of the principles of my invention, Fig. `1 is a longitudinal section of my improved dispenser in' its closed position and as carried or stored.

Fig. 2 is a like View with the cap removed and the plunger fully extended.

Fig. 3 is a like View showing the plunger depressed to discharge a limited portion of the liquid. Y

Fig. 4 is a top plan view with the cap removed. Referring to the drawing, I represents the container, usually a relatively small glass bottle, which is provided with a cylindrical neck 2 exteriorily threaded as at 3. 4 represents a errule, usually of metal, having a portion 5 of larger diameter which is provided with threads for screwing the ferrule onto the neck 2. The ferrule also comprises an intermediate annular shoulder 6 and a portion 1 of less diameter.V The portion 1 is threaded. When the ferrule is screwed down onto the neck of the bottle a rubber or other resilient gasket 8 is compressed between the end of the neck 2 and the shoulder 6 of the ferrule, thus sealing the ferrule relative to the bottle neck.

9 represents a tubular metal barrelwhich extends down through the neck of the bottle and is sealed relative to the neck by the compressed gasket 8. The upper end of the barrel 9 is eX-,

the floor of the bottle. The plug. is provided withan axial bore, the upper end of which acts as a seat for the upwardly opening valve ball I I. The lower face of the head of the plug I0 is provided with radial grooves I2 which act as channels to conduct liquid from the interior of the bottle to the interior of the barrel 9.

The lower bore I3 of the barrel 9 is of greater diameter than its upper vbore I4, with an annular shoulder I5 formed between the two bores.

I6 represents a tubular metal plunger having a lower portion of proper exterior diameter to 5 slidably t the bore I3 of the barrel while its upper diameter ts the bore I4. I'I represents a helical spring interposed between the lower end of the plunger and the upper end of the plug ID, thus tending to maintain the plunger in its 10 raised position in the barrel 9 with the plunger shoulder I3 engaging the barrel shoulder I5, and also to quickly return the plunger to its raised position after it has been depressed and then/released from pressure of the thumb or finger. 35

The internal diameter of the spring Il is sufeient to provide full clearance` for the free movement of the Valve ball VIl in opening and closing.

The barrel 9 is provided with a port I9 which '55 opens into the upper end of the lower bore I3 adjacent the shoulder I5. 2!) represents a second port in the' wall of the barrel which opens into the interior of the barrel approximately half .6 4 Way between the shoulder I5 and the upper end of the bottle. l

The bore of the plunger I6 is closed at its upper end as by the cup 2| and a port 22 is formed in the wall of the plunger and the skirt of the i cup 2| for the forcible discharge of liquid. 0

23 represents a domed cap made of any suitable material and, if desired, of ornamental shape and coloration. The cavityof the cap is of suicient diameter to snugly receive the cup F 2l and close the port 22, preventing leakage of 30 the liquid when the cap 23 is in place as shown in Fig. 1. The lower skirt of the cap is interiorly threaded so as to be screwed onto the exterior threads of the barrel 9.

The lower edge of the cap 23 is'interiorly bev- 40 eled to provide clearance for the portion 'I of the ferrule 4.

The lower edge of the cup 2l is exteriorly tapered as at 24 to fit into the interiorly tapered F upper end 25 of the bore I4. Thus when the 40 cap 23 is assembled it forces these two tapered surfaces together effecting a seal between the plunger and the barrel.

The top of the cup 2|, as shown in Fig. 4, is marked with an arrow or pointer 26, to indicate the side of the cup at which the discharge port 22 is located so that the port may be properly directed in discharging liquid.

When the cap 23 is in place, as shown in Fig.

1, the nquid win tend to stand an the same 1eve1 55 in the barrel 9 and in the bore of the plunger I6 as it stands in the body of the bottle I as the valve ball Il is not spring-seated. When the cap is removed the plunger will spring upwardly until its shoulder I8 engages the shoulder I5 of the barrel and the liquid will tend to follow the quickly ascending plunger.

Now if the thumb be placed in the outer end of the plunger and the latter be quickly depressed into its lowermost position, as indicated in Fig. 3, until the spring I'I is practically fully compressed, the descent of the plunger will seat the valve ball II, trapping the liquid above it in the barrel and plunger and the downward movement of the plunger will forcibly displace the liquid, the momentum of the displaced liquid causing it to be forced upwardly in the plunger and discharged in a jet through the port 22.

Next, when the plunger is released by the removal of the thumb, the expansion of the spring I1 causes the plunger to be forcibly elevated into its position shown in Fig. 2, producing a low pressure condition above the valve ball I I, which causes it to rise from its seat and permit liquid to flow past it to rei-lll the barrel. This refilling ow of liquid is aided by the action of the port I9 in relieving possible back pressure in the barrel and assisting the pumping action of the plunger.

The port 2Q which opens at its inner end into the upper bore I4 of the barrel, in which the plunger has a sliding nt, permits air to leak down between the barrel and the plunger and into the interior of the bottle I, thus to maintain head pressure on the body of liquid in the bottle, this admitted air replacing the discharged liquid.

The resistance to the flow of liquid up between the barrel and the plunger from the port -2l) is much greater than the resistance to the down travel of air, so that there is no tendency to pump liquid up between the barrel and the plunger, but the full pumping action is effective to draw liquid up past the valve ball.

When the cap 23 is screwed into place there is no danger of leakage if the bottle be laid on its side or even inverted.

I claim:-

1. In a dispenser for perfume and the like, the combination of a container, a tubular barrel having one end arranged to extend into the container and sealed therewith, the outer end of the bore of the barrel being provided with an annular inwardly and downwardly tapered surface, a tubular plunger having a portion thereof arranged to operate in the barrel, a cap arranged to be secured to the barrel to close and hold the plunger in its lowermost position, and means on the outer portion of the plunger arranged to engage and eifect a seal with the tapered surface of the barrel to prevent leakage between said parts while the plunger is maintained in its lowermost position.

2. In a dispenser for perfume and the like, the combination of a container, a tubular barrel having one end externally threaded and having the other end arranged to extend into the container i and sealed therewith, the outer end of the bore of the barrel being provided with an annular inwardly and downwardly tapered surface, a tubular plunger having a portion thereof arranged to operate in the barrel, means on the outer portion of the plunger arranged to engage and effect a seal with the tapered surface of the barrel, and a cap internally threaded and arranged to screw onto the barrel forcing the said means into engagement with the tapered surface of the Y barrel effecting a seal therebetween.

3. In a dispenser for perfume and the like, the combination of a container having a tubular neck provided with exterior threads, a ferrule having an interiorly threaded larger bore which is
