1 Claim.

This invention relates to improvements in vapor, powder or liquid spraying devices.

I have found that by constructing a tube or other container of cellulosic material and by 5 providing a small orifice at one end thereof a very practical, economical and efficient sprayer may be provided. A container made of cellulosic material of suitable thickness yields to slight or moderate hand pressure and when the pressure 10 is released the container returns to its original shape. By intermittently depressing or collapsing the sides of the receptacle containing the powder or liquid, a fine spray is emitted through the small orifice which spreads after the same leaves the receptacle.

Such a device affords a very satisfactory medium for dispensing toilet powder over the body, for instance, when the body is moist from perspiration, or after the bath, when it is difiicult 2 to apply powder to the body through the instrumentality of a powder puff, as the latter will absorb the moisture and cause the same to cake on its surface.

In using the usual perforated box or container 25 the powder or liquid cannot be readily directed to the parts to be sprayed.

Devices in use at present are usually made of either cardboard or metal. These materials are subject to cracking or permanently setting, while 30 the cellulosic material intended for this improvement will retain its resiliency, and further permit the use for spraying substances in liquid form.

An object of the invention is to provide a simple, inexpensive and efiicient means for carrying 35 and dispensing powders or liquids or vapors.

Another object of the invention is to provide a container having simple means for ejecting the contained material in a very fine spray.

Another object of the invention is to provide 40 a, refillable tube sprayer.

Another object of the invention is to construct a container and sprayer of cellulosic material, either colored, opaque or transparent.

The invention will best be understood from a 45 consideration of the following detailed description, taken in connection with the accompanying drawing forming part of this specification, with the further understanding that while the drawing shows some practical forms of the in- 50 vention, the latter is not confined to any strict conformity with the showing of the drawing, but may be changed and modified so long as such changes and modifications come within the scope of the appended claim.

65 In the drawing:

Fig. 1 is a view of one embodiment of the invention having a press fit cap and flat bottom.

Fig. 2 is a view of a further embodiment of the invention, the tube having a round press fit bottom and screw cap type of closure. 5

Fig. 3. is a view showing the invention in another modified form, having a nozzle on one end and a screw bottom on the other.

Fig. 4 is a view showing the invention in a further modified form, in which the screw cover 1s provided with a small outlet.

Fig. 5 is an end View of Figure 4 showing the screw cover in detail.

Like numerals refer to like parts throughout the specification. In Figure 1 of the drawing there is disclosed a collapsible tube In having the conventional fiat clamped end I2 and a spout or neck II. Neck l I is provided with a small opening 13. The tube I0 is constructed of thin cellulosic material, and by virtue of its resiliency and yieldability a slight or moderate pressure on tube portion I4 with the hand holding the tube will expel the air contained therein carrying along with it part of the contents. The contents upon leaving the tube I through the small opening l3 will be broken up into a fine spray. Upon releasing the pressure applied, the wall of the tube will quickly return to its normal shape. The thickness of the material is such as to permit of rapid intermittent depressing or collapsing of the sides of the receptacle or tube Ill, to cause a succession of fine sprays of material to be emitted through the opening I3. The spout l I may be covered with a suitable cover or cap I5.

At times it may be desired to have a container of cylindrical shape instead of one having a fiat end portion. In this case a round end piece I6 is inserted either by pressure alone or cemented to the body I8 of the container at its open end l'l. This end piece maintains the container cylindrical. The spout ll may be of the threaded type in which case a threaded cap I9 is employed for closing.

This device is adaptable for spraying insect destroying chemicals, and to facilitate the reaching of insects in cracks or small openings, the sprayer may be supplied with a tapered nozzlelike outlet 20 having an opening 2| at its extreme end. The nozzle 20 may be covered with a suitable cap 22. The tapered opening in cap 22 will assure a tight closing fit with nozzle 20. The tube as exemplified in Figure 3 is shown as of a refillable type, in which there is provided a screw cover bottom 23 engaging the outside threaded portion 24 of the tube 25.

A still further form of the invention is shown in Figure 4, in which the container 26 has a rounded closed end 21, and an internally threaded screw cover or cap 28 engaging its openable end. This cap may be made of metal or any other suitable material. The ejecting opening 29 is provided in the cover 28.

It is understood, that any combination of the various forms illustrated may be employed, and that there are other modifications possible, which are contemplated as being within the scope of the invention, so that while certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claim.

Having thus described my invention, what is claimed as new and desired to secure by Letters Patent, is:

A sprayer comprising a substantially cylindrical body constructed of cellulosic material and having an open end, and a removable cap for closing said end, the cylindrical wall of said body being of such resiliency as to be yieldable by mod erate hand pressure whereby when depressed and upon the pressure being released adapts it to quickly resume normal shape, by which to cause rapid intermittent collapsing of the wall, said cap having a minute opening through which material in the body may be dispensed upon application and release of such pressure.

HENRY F. COLVIN.
