2 Claims.

This invention relates to a dispensing receptacle for volatile liquids.

An object of the invention is to provide a simple, cheap and effective device of this character embodying novel and superior features of construction making for advantages not hitherto obtainable in a device of comparable simplicity and cheapness. A more limited object is to provide a novel means for supporting a spring operated device for closing the dispensing opening. A further object is to provide novel spray forming means and a still further object is to provide a novel means for dispensing a predetermined quantity of liquid.

Other objects will be in part apparent and in part pointed out hereinafter in connection with the accompanying drawing wherein Fig. l is a part sectional elevation showing one form of my.

invention and Fig. 2 is a section corresponding substantially to the'line 2-2 of Fig. 1.

The device consists essentially of a receptacle ID and a closure indicated generally by the numeral II. The closure ll includes a cap element l2 whichmay be threaded or otherwise secured over the neck of the receptacle Ill and which is provided with a central bore 13 extending therethrough. Projecting upwardly from the upper surface of the cap element I2 is a boss I l which is externally threaded. Received on the boss at is a lever attaching plate i5 having a laterally extending portion 56 provided with upstanding ears I! to which is pivoted a lever i8. Received on the boss I4 is an internally threaded nozzle element it which is provided with an interior cavity 2%! and a capillary outlet opening 2i. The cavity 29, as is clear from the drawing, constitutes an expansion chamber between the bore l3 and the capillary opening 2|. The lever l8 carries a deformable sealing element 22 which is adapted to engage the nozzle 89 in closing relation to the capillary opening 2|. This lever is spring-pressed by a spring 23 to the position shown in Fig. 1 and may be moved out of alignment with the opening 2! by depressing the lower end toward the receptacle I0. I have found that by providing the expansion chamber in the passage from the interior of the receptacle to the exterior of the nozzle, I am able to produce a spray when using, for example, ethyl chloride which is ejected under the force of its own vapor pressure, and that a jet stream does not result as would be the case were the expansion chamber not provided. The attaching plate i5 is clamped between the nozzle l5 and the :cap' it and the portion It may be positioned at any point around the cap. This feature is of importance particularly when receptacles of non-circular cross section are used.

On the interior of the cap 12 I provide a depending skirt 24 which' defines a cavity in communication with the bore l3. Within such cavity I place a quantity of fibrous material 25 such as cotton, wool, spun glass, metal wool or the like. I find that this material will, upon inversion of the receptacle, absorb a quantity of liquid which upon depression of the lever 18 while the receptacle is in upright position will be ejected under the force of the vapor pressure of the volatile liquid. This affords a convenient means of delivering a predetermined bulk and one which may be varied by the simple expedient of placing a different quantity of the fibrous material in the cavity. Care must be taken not to add so much of the fibrous material that free passage of vapors will be prevented. Indeed, I prefer to use a quantity of fibrous material less than that which will result in the maximum liquid retention within the space defined by the skirt 2%, since a greater quantity obstructs the flow of liquid without advantage. I have also discovered that by the use of the fibrous material within the skirt 2t as a means oi. predetermining the bulk to be dispensed, I am able to produce a spray even though the expansion chamber 20 is not provided. Thus in cases where the fibrous material is employed, a nozzle of different design, not providing an expansion chamber, may be employed. It is to be noted that the cavity defined by the skirt 2 5 may be of a size greater than would support any considerable quantity of liquid by capillary attraction without the fibrous material. In the event the receptacle is to be used for dispensing a quantity of fluid which is not predetermined, the lever l8 may be depressed while the receptacle I0 is in inverted position whereupon an indefinite quantity of fiuid will ,be expelled. In case the capability of dispensing a predeter-. mined bulk is not desired in any particular container, the fibrous material 25 may be simply omitted.

It will thus be seen that I have provided a container which, while simple and inexpensive, lends itself readily to a wide variety of uses and while I have shown and described thepresent preferred embodiment I do not wish to be limited to the details of the disclosure but only in accordance with the appended claims.

Having thus described my invention, what I claim is:

l. A dispensing device comprising, in combination, a receptacle and a closure therefor, said closure including: a cap element having a boss projecting from the outside thereof, a bore formed in and extending through said cap ele-- ment and through the bossthereof, a nozzle element sealed over the outside of said bus and having a short capillary passage extending to the outside thereof, and movable means normally closing said capillary passage and adapted to be "operated manually for movement to uncover said passage, said nozzle element and said capillary boss defining an expansion chamber between said bore and said capillary passage.

2. A dispensing device comprising, in combination, a receptacle'and a closure therefor,

said closure including a cap element detachably mounted on said receptacle and having a boss and projecting from the outformed therewith ment to uncover said capillary passage, said nozzle element and said boss defining an expansion chamber between said bore and said capillary passage.
