Qur invention relates to new and useful improvements in bottle closures and liquid dis pensers, for dispensing liquids, preferably such liquids as have an undesirable odor, or injurious :5. effect upon the persons hands or clothing handling'the same, since it is very effective in the .use of such liquids without spilling the same.
In practice this dispenser is normally applied to a container, such for instance as a bottle,
110 preferably one having a threaded circular neck portion to permit of the use of a threaded cap to insure an easy and secure attachment to the container.
.An object of the invention is to so construct .15 the same as. to form a shipping seal for the con- ;tainer .to which it may be attached and thus require no auxiliary part for effecting aliquid itight" seal. 7
A further and important object of the inven- {20 tion. is to provide a combined bottle closure and dispenser in a single unit which can conveniently .be applied and removed from a container and Lwhich will be simple in construction, inexpensive ,Tto manufacture, convenient, durable and serv- More ispecific objects of the invention will become apparent from a consideration of the following. description taken in conjunction with the drawing illustrating the construction and use of ,3!) the invention, and wherein:
' Fig. 1 shows a perspective view of a bottle in an inverted position and provided with our improved dispenser which is shown supported and being operated as in the hand of an operator.
r35 .Fig. 2 shows .a slightly enlarged vertical sec- .tion of the dispenser shown in Fig. 1, applied to the neck of a bottle and in an upright position.

"" Fig. 5shows a, similar vertical cross section 45 of the inner metal'member of the dispenser,
which includes dropper, so-called.
Fig. 6 is a detached vertical cross section of the rubber diaphragm shown in Fig. 2, and f- Fig. '7 shows a further vertical section of a 5,0 modified form of the dispenser.
* The dispenser, as will be seen, is made up of comparatively few parts, two metallic members,
a rubber diaphragm and a sealing washer. The same are constructed to be easily and effectively ;:5,5 assembled=to form a single operative unit which can readily be attached and detached from the neck of the container as in the dispensing of liquid. The operationof this dispensing is obviously governed entirely by the amount of pressure exerted on the rubber diaphragm after the dispenser has been detached from the container. In fact, it may be used either in the form of a dropper, or dispenser of liquids in larger quantities; The use of the dispenser is not necessarily confined to medical solutions and disinfectants, but is equally well adaptable for perfumes, toilet water, etc.
A distinguishing feature of our present dispenser is that the container to which the dispenser is applied requires, for the operation of the dispenser, that the container be first inverted, see Fig. 1 of drawing, and then that the rubber diaphragm be compressed inwardly and released, causing the fluid to be sucked in and completely fill the dispenser chamber with liquid. After this operation the bottle is uprighted and the dispenser removed therefrom by unscrewing it, whereuponthe contents of the dispenser may be emptied by a dropping operation or the complete contents discharged if desired.
In the embodiment of the invention herein shown, Ill indicates a container in the form of a glass bottle, which is shown supported in an inverted position by the hand of an operator, in the act of compressing the flexible disk H of the container I2 threadably attached to the neck of the bottle. Referring to Fig. 2 wherein the bottle neck is shown in an upright, rather than inverted position, the several attached parts of the dispenser are clearly illustrated in the cross section, and as will be seen includes an outer threaded shell M, an inner shell l5 and the beforementioned rubber diaphragm l I, a washer It being employed asbetween-the annular top edge of the neck of the bottle, the inner wall of the attaching cap l4 and the underside of the shouldered portion ll of the inner member l5. The attaching shell l4 includes a depending threaded cylindrical por tion l8 adapted to engage corresponding threads l9 formed in the annular surface of the bottle neck. The upper portion of this shell Hi includes an outwardly disposed annular portion forming a shoulder upon which the annular flange iii of the inner shell is seated. The ribbed annular bottom edge portion 22 of the diaphragm H is seatedupon the flange 2| and the upwardly disposed edge portion 23 of the shell I4 is rolled over the annular bead of the diaphragm and is pressed down into an annular recess to insure a secure attachment of the diaphragm to the shell and to form an integral assembly of the several parts of the dispenser. The inner shell I5 is shaped to form the annular shoulder I! previously mentioned on its underside and also a depending circular wall portion 24 wherein the washer I6 is seated so as to be retained within the dispenser and to engage the annular top edge of the neck of the bottle when thedispenser is attached as shown in Fig. 2. The central portion of the inner shell is drawn together, funnel-like, to produce a dispensing spout 25 through, whichthe dispenser chamber 26 is filled by the operation. of the diaphragm and from which the contents is discharged from the dispenser chamber after'it has been filled and removed from. the bottle.
The modification shown in Fig. '7 includes. a spring 2l' that is contained within the liquid chamber 26 formed within the dispenser as -between the inner shell I5 and the diaphragm! I. The upper end portion of the coiledspring is centered with respect to the inner central portion ofthe diaphragm by means of: a; lug 28 formed upon the inner side of the diaphragm and an annular shoulder 29-formed in the top surface of the inner shell as shown in Fig. '7. This spring is obviously for the purpose of lending resistance to the rubber cap and to prolong its usefulness.
' In the operation of the dispenser which flrst includes the filling of'the liquid chamber, the bottle is inverted substantially as illustrated in Fig. l and the diaphragm pressed in order toform a vacuum and then releasedlin a'. way tosuck the liquid into the chamber, Thecontainer is then uprighted and the same removed from the bottle by unscrewing the dispenser, including the threaded shell, then the dispenser supported over the object upon which the liquid is to he applied, whereupon the operator againpressesdownupon the diaphragm in a manner to discharge the contents, in the chamber of the dispenser, the amount of: pressure exerted upon the diaphragm determining whether the solution is to be dis charged in drops or in larger quantities.
