1 Claim.

This invention appertains to new and useful improvements in dispensers, and more particularly to a bottle attachment.

The present invention has for its chief aim to provide means whereby the fluid contents of a bottle can be placed under compression and thus dispensed at will.

An important object of the present invention is to provide a pump and valvular attachment for bottles whereby the contents of bottles can be dispensed under pressure.

Another important object of the invention is to provide a device of the character stated which can be readily attached to various types of bottles without any inconvenience and used efficiently without likelihood of any defects occurring.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the attachment applied to a bottle.

Figure 2 represents a vertical sectional view through the structure shown in Figure 1.

Figure 3 represents a top plan view of the attachment.

Figure 4 represents a horizontal sectional view taken substantially on line 4--4 of Figure 2.

Figure 5 represents a horizontal sectional view taken substantially on line 55 of Figure 1.

Figure 6 represents a side elevational view of the pump unit.

Figure '7 represents a cross sectional view taken substantially on line 77 of Figure 6.

Figure 8 represents a perspective view of the valve element.

Referring to the drawings, wherein like numerals designate like parts, it can be seen in the drawings that numeral 5 represents a bottle and numeral 6 generally refers to the dispenser attachment. This dispenser attachment consists of a head '7 and a depending cylindrical apron 8, within which is placed the core 9 having an annular shoulder 10 therein against the bottom side of which fits the resilient washer 11 and against this will bear the upper end of the bottle 5, as clearly shown in Figure 2.

A wire swingable hook 12 is carried by the apron 8 and the hook portion 13 thereof is capable of engaging under the neck bead 14 of the bottle so that the packed shoulder 8 of the core 9 will be maintained snugly against the upper end of the bottle.

Extending vertically through the core 9 and having its upper end threaded int-o the head '7 is the pump barrel 15, this barrel depending a substantial distance below the apron 8 and being closed at its lower end, as at 16, excepting for a small duct 17 which is normally closed by the check valve ball 18. A basket type coiled spring 19 is fixed to the lower end of the barrel 16 and retains this ball 18 normally seated within the duct 17. Numeral 20 represents a plunger operative within the barrel 15 and from this extends the rod 21, this rod extending upwardly TY through the head 7 and terminating in a handle 21. Obviously, by operating this handle, the plunger 20 can be operated to force air into the bottle 5 and place the contents thereof under pressure.

Numeral 24 represents a spout on the head 7 having a duct 25 opening therethrough, the inner end of the duct communicating with the small chamber 26 which is normally closed by the valve element 27. This valve elements 2'7 is of cup shape and has a packing element 28 thereon and a stem 29 extending therefrom upwardly through the head 7 to terminate in a button 30 which is detachable and which is provided with a skirt 31 snugly operating in the recess 32. A coiled compressible spring 33 is interposed between the bottom of the recess 32 and the button 30 and partly within the skirt 31 so as to normally maintain the button elevated and the valve element 27 against the seat 34 for closing off the duct 25 from the interior of the dispensing attachment and interior of the bottle 5. A bumper spring 34 is provided on the plunger rod 21, as is clearly shown in the drawings and a tubular projector shell 36 is provided for the lower end of the pump valve 15.

Resilient packing washers can be placed at the upper end of the core 9 and at the upper end of the pump barrel in the head '7 and it will be observed that the cylindrical apron 8 has a sleeve at the lower end thereof and this serves to retain the resilient washer 11.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is: w A dispenser attachment for bottles comprising a shell having a closed top and an open bottom to receive the neck of a bottle, and an air pump including a barrel extending upwardly in the shell and being anchored at its upper end in the closed top of the shell and depending substantially below the shell, a plunger operative in the barrel, a stem extending from the plunger and being slidable through an opening in the top of the shell, a handle on the outer end of the stem for operating the same, a discharge nozzle on the shell, said closed end of the shell being provided with a bore therethrough at the inner end of the nozzle, said bore and noz zle merging at the inner end of the bore,

a valve at the inner end of the bore for normally closing the nozzle, a stem extending from the valve and through the bore and provided with a finger button at its outer end, said button being located in close proximity to the
