UNITED STATES PATENT OFFICE v JOHN L. MCATREE, OF NEW YORK, N. 'Y., ASSIGNOR TO SCOVILL MANUFACTURING COMP-ANY, OF WATEBBURY, CONNECTICUT, A CORPORATION 01 CONNECTICUT nssnnon DISPENSER Application filed August 9,1926. Serial No. 127,993.
This invention relates to certain improvementsin dispensing containers, and particucontainer at a time, as owing to the high concentration but very little is needed or desirable. It is, furthermore, desirable in dispensing preparations of this kind that the containerbe so made that the essence can be dispensed very easily, and preferably by a wiping action. And it is, furthermore, des1r-- able that the container should be practically leak proof so as to prevent, as far as possible, evaporation and consequent loss of the essence.
It is a special object of the inyention to produce a dispenser for dispensing essence in which but a small quantity of the essence is dispensed at a time and by a simple wiping action, the dispensing closure for the container being so constructed as to be practicallyleak proof and thus prevent escape by vaporization or otherwise of the essence.
A further object of the invention isto produce a dispensing closure for these containers which shall be of simple form and few parts so that it can be produced commercially at low cost and, if desired, can be secured to the container with which it is used so that it cannot be removed therefrom without deforming the closure, thus guarding against refilling, which is a desirablefeature, particularly where the closure is used forv dispensing costly perfumes. v
With these and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described in connection with the accompanying drawings and the novel features pointed-out in the claim hereunto annexed.
In these drawings;-
Figure 1 -is a side view of' the improved closure, the container to which it is attached being shown in broken lines; 1
Figure 2 is a top view of the closure shown in Fig. 1;
Figure 3 is a central vertical section showing the parts in closed position;
Figure 4 is a similar section showing the .parts' in dispensing position, and
1 Figures 5 and 6 are partly section, fpartly broken away views showing the di erent ways in which the closure may be secured to its container.
Referring now to these drawings, the contalner for the essence is the usual glass vial,
marked 1, this container, in the'construction shown in Figs. 1 to 4, being provided with an annular groove 2 forming a shoulder 3.
The invention will include 7 an improved closure for this container, and preferably the closure will be so positioned on the container that it cannot be removed therefrom without deforming the closure to such an extent that it will be obvious that it has been removed from the container with which it was originally assembled. While the specific construction of the closure may be of various charlie-- ters, it will include a dispensing orifice closed by a valve, and a sealing medium will be employed on each side of the valve so as to seal the contents of the container when in non-use I and thus prevent, as far as possible, loss of the contents of the container. i
In the specific constructionillustrated, the improved closure includes a casing of light metal=provided with a skirt 4 of substantially the same diameter as that of the neck of the vial with which it-is to be used. The skirt 4 inclines inwardly, as indicated at 5, and terminates in a reduced neck, portion 6 pro- "vided with a top 7 which, preferably, is flat,
although, I if desired, it may be somewhat rounded, and this top 7 is provided with a small. dispensing orifice 8.
This orifice is controlled by a valve shown in the form of a member having a, stem 9 which projects beyond the top of the valve,
"and is. for purposes hereinafter referred to,
provided with an end having rounded or curved sides 10. This valve has secured thereto or made integral therewith a hollow head 11 which has a sliding movement in the neck 6 of the closure. For normally keeping coil seating in the hollow head 11.
, this operation.
this valve closed, there is provided a spring, shown in the form of a coil 12, one end of the In order to prevent, as far as possible, es-
cape of the essence from the container and to facilitate the'securing of the closure on its container, the closure is provided 'on each side of the valve with a sealing disc of suitable compressible material, such as cork. Thus there is provided a large sealing disc 13 which is formed with rounded upper sides 14 to correspond with the rounded upper sides 5 of the shell 4. The lower face of this sealing disc is fiat and is adapted to seat on the edge 15 of the bottle neck. This sealing disc has close frictionalenga'gement with the shell and is provided with an aperture 16 through which the essence may pass into the neck 6. The upper face-of this sealing disc acts as a seat for the lower end of the coil spring.
Above the head 11 and snugly fitting the valve, is a second sealing disc of suitable compressible material, such as cork, marked 17 which is provided with a central aperture to receive the valve stem 9. This sealing disc, when the parts are closed, snugly engages the lower face of the inside of the top 7 of the closure and effectually seals the opening 8 against the escape of the contents of the container.
The closure may be applied to the container in various ways. In the construction shown in Figs' 3 and 4, the parts are assembled with the sealing discs, valve and spring in place, and the closure is then secured to the container by spinning or turning in the lower edge 18 of the skirt 4 so as to engage under the shoulder 3 formed in the container neck, the disc 13 being compressed during With this construction, the parts are effectually sealed and the closure cannot be removed without deforming itE A somewhat modified construction for effecting the same purposes is illustrated in- Fig. 5. in the construction there-shown the container instead of being formed with a groove is' formed with a bead 19,'an-d the lower portion of the skirt 4: is turned or spun over this head. Under some circumstances, particularly where dispensing cheaper grades of essence,
or where for other reasons it may be desired,
the closure may be simply screwed on the container, the skirt 4 being formed for this purpose with a thread 20 which engages a corresponding thread 21 onthe container neck.
With the construction shown and de-. scribed, it will be seen that a closure has been provided for dispensing small quantities of essence which will function on a slight downward pressure being applied to the valve stem 9, as by rubbing iton the hand or other part of the anatomy of the user. It will be observed that by-roundingthe end of the valvethe sli ht pressure necessary to unseat the valve to e position shown in Fig. 3 may be attained at practically any angle, so that it is very convenient for the user, as little pressure is sufiicient to unseat the valve to permit-the desired amount of essenceto be dispensed. \Vhile the invention has been shown and described in its preferred forms, it will be understood, of course, that various modi-- fications in the container, the method of fastening the closure thereto, and" the valve structure/may be made without departing from the invention as defined in the appended'claim.-
What is claimed is:
In a perfume dispensing device, a portable container, a dispensing closure therefor capacitated to dispense perfume in small quantities andincluding a shell having an enlarged base secured to the container and an inwardly turned shoulder, a packing disc betweentheshoulder and the top of the con- .tainer, a reduced neck extending above the shoulder. and terminating in an inturned peripheral flange provlded with a dispensing orifice and forming a seat, a packing disc seated against the seat, a valve having lon itudinal movement through the top of t e closure for closingv the dispensmg orifice, and a spring normally hol-dingthe valve inclosed position.
In testimony whereof, I have hereunto set my hand. r
