11 Claims. (Cl. 43-146) This invention relates to a combined powder container and dispenser and, more particularly, to a powder dispensing box of the squeeze type.

In the use of various powders such as toilet powders and insecticides or other dusting powders and the like, it is frequently desirable to provide a convenient method to spray out the powder in the form of a fine cloud of dust. In this way it is possible to obtain the full value of a finely divided powder, since in the fine cloud each minute particle is substantially separated from each other particle. A maximum covering effect may thus be obtained from a minimum use of material and, in addition, the powder may be blown into ordinarily inaccessible places.

It is a prime object of the present invention to provide a powder box which is adapted to eject powder in the form of a fine cloud.

it is another object of the invention to provide a combined powder box and powder sprayer whereby a powder may be stored and then ejected, when used, in the form of a fine cloud.

A further object of the invention is to provide a combined powder box and sprayer-with an improved form of discharge and diffuser nozzle.

Still another object of the invention is to provide a combined powder box and powder sprayer with an annular closure strip serving as an advertising medium.

It is further proposed to produce a combined powder box and powder sprayer that is simple in construction and that can be manufactured and sold at a reasonable cost.

For further comprehension. of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly setforth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a combined powder box and powder sprayer embodying the invention.

Fig. 2 is an enlarged side elevational view thereof shown in operative position between the fingers of the user.

Fig. 3 is a vertical sectional view taken on the plane of the line 33 of Fig. 1.

Fig. 4 is a fragmentary vertical sectional view taken on the plane of the line 4--4 of Fig. 3, the parts being shown in closed condition.

Fig. 5 is a horizontal sectional view taken on the plane of the line 55 of Fig. 3, the parts being shown in open condition for spraying.

Fig. 6 is a perspective detail view of the discharge nozzle.

Fig. 7 is a fragmentary vertical sectional view similar to Fig. 3 but showing a modification of the invention.

Referring to the figures of the drawing in detail, the combined powder box and powder sprayer made in accordance with the invention comprises a body section ited States Patent 0 10 and a cover section 11 preferably formed of suitable plastic material. The body section 10 is hollow and cylindrical in cross section and may be of any desired diameter and any desired length to constitute the height of the box, these dimensions determining the capacity of the box as will be understood. The body section includes :a thin flexible circular disc 12 constituting the bottom wall of the box and which is provided with integral upstanding spaced inner and outer flanges 13 and 13', respectively, formed thicker than the bottom wall and serving as part of the side wall of the box. A thin peripheral flange 14 extends radially around the bottom end of the upstanding flange 13'. The top of the body section is open.

The cover section 11 includes a thin rigid or nonflexible circular disc 15 constituting the top wall of the box and is provided with a depending flange 16 formed thicker than the top wall. A thin peripheral flange 18 extends radially around the top end of the depending flange 16. The internal diameter of the depending flange 16 is slightly greater than the external diameter of the upstanding flange 13 of the body section so that the cover section loosely fits over the open end of the body section, with its flange 16 fitted in the space between the

flanges

13 and 13, and its flange 18 seating on flange 13 of the body section 10, thereby removably closing the open top end of the body section to permit filling of the body section with powder.

The

discs

12 and 15 constituting the bottom and top walls of the powder box are formed ooncavo-convex, with the convex side outermost and with the opposed centers of the two walls farthest apart.

A cutout 19 is formed in the upstanding inner flange 13 of the body section 16, which cutout is rectangular in shape and extends from a point remote from the disc 12, forming a ledge 20 adjacent the disc, to and intersecting the upper edge of the flange 13 as shown in Fig. 3. An opening 17 is formed in outer flange 13' in line with the cutout 19. A discharge nozzle device 21 is mounted in the cutout 19. This nozzle device is formed of suitable plastic material and as shown in Fig, 6 comprises a tubular member 22 extending radially from an integrally formed backing plate 23, inwardly to the interior of the body section 10. The backing plate 23 is slig tly curved to conform to the curvature of flange 13 and is formed with a lower offset portion 24 disposed outwardly of the flange 13 and seated on the peripheral flange 14 of the body section 10. The dimensions of the backing plate 23 are slightly larger than the dimensions of the cutout 19 so that the side edges of the base plate engage the inner surface of the flange 13 on both sides of the cutout, with the bottom offset portion 24 thereof disposed between

flanges

13 and 13 and engaging the outer surface of said flange 13, thereby closing the cutout 19, with the tubular member 22 seated on the ledge 20. The nozzle device may be secured in position by applying a suitable adhesive on the flange engaging portions thereof. A pin hole 25 is formed in the backing plate 23 centrally of the tubular member 22 in line with opening 17 in flange 13' and the tubular member 22 is formed with spaced ribs 26 extending the length thereof around said hole 25.

A thin annular band or ring 27 of plastic material encircles the outer flange 13 of the body section 10' and forms part of the side wall of the box. The band or ring seats on the flange 14 of body section 10 and is turnable around the flange 13' in the direction of the arrows on Fig. 1 and is guided in its movements by flanges 14 and. 18. The band is formed with a pin hole 28 adapted to be moved into register with the larger opening 17 in the flange 13 of the body section 10 andwith the pin hole25 in the nozzle device 21. The band may have 3 suitable advertising indicia thereon, such as indicated at 29.

If desired, the top wall 15 of the box may have suitable decorative effects such as indicated at 30.

In use, the outer band 27 is turned until the hole 28 therein registers with the opening 17 in the outer flange 13 of the section and with the aligned hole 25 in the nozzle device. The box is then held in the hand between the thumb and forefinger as shown in Fig. 2 and the bottom wall squeezed toward the top wall whereupon the internal area or capacity of the box is reduced and an outward pressure or flow of air within the box is exerted which finds exit through the tubular member 22 where it is further diffused by the ribs 26. From the tubular member 22 the powder is forced through the hole 25 in plate 23 and through the aligned opening 17 in flange 13' and hole 28 in the outer band 27 in the form of a spray as shown in Fig. 1.

In Fig. 7, a modified form of discharge nozzle device and mounting therefor are shown. In this form, the tubular member 22 is formed with ribs 26' arcuately shaped in cross section with sharp points 31, the pointed ends of the ribs being arranged in overlapping concentric relation so that the powder passing through the tubular member is deflected from one rib to another and is effectively broken up into particles.

The cutout 19' is formed with an enlarged upper end having its upper end edges 33 curved. The curved edges 33 facilitate entrance into the cutout of the nozzle device, and the cutout is enlarged to accommodate laterally extending lugs 34 on the backing plate 23 so that when the nozzle device is inserted downwardly into the cutout 19', the lugs 34 will cam against the edges of the cutout and wedge the nozzle device in position against displacement.

In all other respects, the form of the invention shown in Fig. 7 is similar to the form shown in Figs. 1 to 6, inclusive, and similar reference numerals are used to indicate similar parts.

It will thus be seen that a simple and economically manufactured box has been provided for the purpose of containing powder of any kind and of dispensing the same in the manner of a bellows, the ribs, in the tubular member serving to break up the particles of powder into a fine dust. The box may be made of any height or diameter depending upon the use to which it is to be put.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
