March 4,1958 M. E. ALTERGOTT SPRAYING DEVICE Filed Nov. 10, 1953 U wds e cs Pm "07 cc SPRAYING DEVICE Mary E. Altergott, Chicago, 111. Application November 10, 1953, Serial No, 391,211

' 2 Claims. c1. 299-90 This invention relates to improvements in a spraying device, and more particularly to a spraying device highly desirable for dampening clothes prior to ironing the same, although the device will have other uses and purposes, such as watering plants, the spraying of insecticides, etc., as will be apparent to one skilled in the In the past, many and various types of spraying devices have'been developed. In many cases these formerly known devices, particularly for dampening clothes, were of the shaker type utilizing a rigid container, an apertured cap, and the device had to be forcibly shaken to discharge the liquid through the cap. The use of such devices resulted in uneven wetting, they were tiresome to the user, and could not satisfactorily be used by the debilitated, elderly, or physically handicapped. Other types of spraying devices heretofore developed involved the use of a container having a resilient wall which, when pressed, caused the forcible discharge of the liquid contents. These devices frequently had a center discharge opening and as such were not arranged to provide anything but a concentrated stream of liquid, rather than a delicate and highly diffused spray. Further, as made heretofore, refillable spraying devices frequently required the addition of a gasket or other sealing means to prevent leakage, which sealing means could become lost or displaced to the aggravation of the user.

With the foregoing in mind, it is in an important object of the instant invention to provide a spraying device that is extremely easy to use, light in weight, and so may properly be handled by the elderly, crippled, or otherwise physically handicapped.

Also an object of this invention is the provision of a spraying device requiring extremely little energy to manipulate, and which is so designed as to provide a delicate highly diffused spray which results in evenly wetting the sprayed surfaces.

Also an object of this invention is the provision of a spraying device including a container with a removable cap, and with which no extraneous sealing means whatever are necessary in order to prevent leakage.

It is also a feature of this invention to provide a simply constructed and economical spraying device, manually manipulated, and which will spray effectively in substantially any direction.

A further feature of the invention resides in the provision of a spraying device comprising a bottle or container made of a plastic material, and having a resilient side wall, with a removable cap that automatically efiects sealing engagement with the mouth of the bottle or container when placed in position thereon.

While some of the more salient features, characteristics and advantages of the instant invention have been above pointed out, others will become apparent from the following disclosures, taken in conjunction with the accompanying drawing, in which- Figure l is a side elevational view of a spraying device embodying principles of the instant invention;

. Fatented Mar. 4, 1958 Figure 2 is an enlarged central vertical sectional view of the structure of Fig. 1, indicating the operation of the device, in exaggerated style, for spraying at a downward angle;

Figure 3 is an enlarged top plan view of the closure or cap element only;

Figure 4 is a fragmentary central vertical sectional view illustrating a modified form of closure or cap element; and F Figure 5 is a top plan view of the closure element of As shown on the drawings:

The illustrated embodiment of the instant invention shown in Figs. 1 to 3 inclusive, comprises a container 1 which, for illustrative purposes, is shown in the form of a bottle having a relatively narrow neck 2 provided with an outstanding integral thread 3 to accommodate a screw type cap. Now with reference to Fig. 4, which shows the same bottle or container construction, it will be noted that the threads do not start at the outer edge of the neck, but are spaced inwardly therefrom a distance sufficient to provide a true cylindrical and smooth side portion 4, and the outer edge of the neck is cut off or terminates squarely to provide a flat annular shoulder. 5 surrounding the mouth of the container.

This bottle or container 1 is preferably made entirely in one piece and of a suitable lightweight plastic material such as polyethylene. The bottom and upper shoulder of the container may be thickened or otherwise made stiff,

but the side wall of the container is readily flexible as shown in Fig. 2, wherein the wall is illustrated as squeezed inwardlyat 6, from the normal position of the wall indicated by the dotted lines. Of course, the resilient wall, when released, automatically assumes normal position as seen in Fig. 1, or as denoted by the dotted lines of Fig. 2.

Again with reference to Figs. 1, 2 and 3, it will be seen that the closure or cap element, generally indicated by numeral 7, comprises a skirt 8 having an integrally threaded portion 9 formed therein, which is complemental to the threads 3 on the bottle, the skirt terminating in a reinforcing bead 10. The upper portion of the skirt is free from knurling or other gripping configuration, to define a smooth cylindrical portion 11 for intimate contact with the smooth cylindrical portion 4 on the bottle neck. The top of the skirted or cup-like cap 17 is also provided with a flat annular portion or rim 12 for intimate contact with the fiat outer edge 5 of the bottle neck, as seen in Fig. 2. Inside that flat annular portion 12 the cap is outwardly domed as shown at 13. The major portion of this domed part is imperforate or solid.

Of course, apertures for the discharge of liquid from the bottle are provided in the cap. With reference more particularly to Fig. 3, it will be seen that these apertures 14 are relatively minute in character, are widely spaced, and are disposed in circular formation in the dome portion 13 of the cap, but are preferably immediately adjacent the circumference of that dome portion. In other words, the apertures are preferably in the dome part itself, but located where that dome part rises from the annular fiat rim 12. While the apertures may vary in number, depending upon the use to which the spraying device is to be put, six such apertures are highly satisfactory for most ordinary uses. Outside of the single circle of apertures 14, the cap is imperforate.

The complete cap itself may economically be made of metal for durability, or of plastic, if so desired.

In use, it is a simple expedient to remove the cap 7, till the bottle fully or partially with whatever liquid is desired to be sprayed, and simply screw the cap in place on the bottle neck. The screwing of the cap in place on the bottle neck effects a' liquid tight seal between the smooth cylindrical portion 11 ofthe cap skirt and'the corresponding cylindrical part 4 on the neck of a bottle, and between .theannular flat rim.12 of the cap and theouter edge of the bottleneck. .iNo extraneous means such .as a gasket are necessary. at any time. After the .bottle has been so readied, it is a simple expedient to'li'glifly {Press the sides of the. bottle. and a delicate highly .diflused spray of liquid will emanate in any desired. direction. @The showing inFig. .2 ishighly exaggerated as to theamount of pressure necessary, and it would. not ,bedessentialto squeeze the bottle wall to the extent shown in Fig. 2,..unless thebottle were,,-praetically,empty. In.fact, ,avery light compression of the side of the bottle is sufiic'ient-to provide a satisfactory spray which accomplishes even wettinghof a sprayed surface.

InFigs. 4 and 5 .I ,havejillustrated.a ditferentjjform of captorclosure element, generally indicated l-by .numeral .15. This formof capvmay well hemolded' from aplastic .or ceramic material and .includes anonter hollow dome portion 16 and an elongatedrexterna'lly taperedhollow neck 17. This neckisiforinsertion inside .the bottle neck 2 as seen in Fig. 4, andin this .instanceextraneous sealing means are necessary, and may satisfactorily be in the form of a sleeve 18 of cork or other suitablematerial surrounding the neck 17.

As seen more clearly in Fig. 5, .the major portion of the dome 16 is imperforate, and spaced well away'from the center of the dome is a-similar set of minute apertures 19, widely spaced in circular formation.

The use or" the embodiment seen in Figs. 4 and 5 is substantially the same as thatabove described in connection with Figs. 1 to 3 inclusive, although the structure of Figs. 1 to 3 is perhaps moreeconomical and simpler to manipulate.

From the foregoing, it is apparent that I have provided a simple, lightweight, economical and easily operable spraying device which efl ects a delicate highly diffused sprayfor even wetting, and which device may readily be handled by an enfeebled operator.

It will be understood that modifications and variations may be efiected without departing from the scope of the novel concepts of the present invention.

I claim as my invention:
