11 Claims. 1
My invention relates to a powder sprayer or duster.
One of the principal objects of this invention is to providea simple and economical article of manufacture whereby powder of various kinds, such as talcum, insecticide, and. the like, may be sprayed, and thereby more or less finely and uniformly spread, dispersed, or dusted.
Another important object of this invention is to provide means of finely and uniformly spreading, dispersing or dusting powder in connection with or on a flexible and resilient bulbous container, and a container from which such means may be readily removed so that the container may be readily refilled with powder.
An important object also is to provide a means of this class in connection with or on such a bulbous container whereby air may be quickly or readily drawn into the container, but from which the air may be exhausted at a much slower rate while powder is suspended in the exhausted air.
A further important object of this invention is to provide simple and economical means of causing the powder to be blown uniformly from the container and suspended in and spread with the exhausted air.
Still another important object of this invention is to provide an article of this class which may be used interchangeably as a powder spreader or a syringe. I
With these and other objects in view, as will appear hereinafter, I have devised a powder sprayer having certain novel features of construction, combination, and arrangement of parts and portions, as' will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the'accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:
Fig. l is a longitudinal sectional view of my powder sprayer in one form of construction, showing by dotted lines the reverse position of the nozzle;
Fig. 2 is a fragmentary longitudinal section, showing a modified form of the construction of the nozzle, which may also be reversed;
Fig. 3 is a fragmentary sectional view of the normally inner'end of the nozzle when the device is used as a powder sprayer, or the outer end of the nozzle when the device is used as a syringe;
Fig. 4 is a fragmentary longitudinal section of my device, showing another slightly modified form of a spray nozzle therefor; and,
I for filling the same with powder.
Fig. 5 is a transverse sectional view thereof, taken through 5-5 of Fig. 4.
The container for holding the product to be spread, dispersed, or dusted, designated l, is a contractable container, and is preferably of a compressible bulbous form, such as the rubber bulbs commonly used in syringes.
The neck i of the bulbous container has a relatively large opening l which is hereinafter referred to as the filling opening. The walls of this opening preferably have internal threads I for receiving an enlarged externally threaded portion 2 of a nozzle member 2. This nozzle member has an axially inwardly extending tubular portion 2 which has a constricted opening 2 at its inner end.
At the outer end of the nozzle member, and in axial alignment with the tubular portion 2*, is a recess 2 in which is secured, preferably frictionally, a nozzle tip 3, which is of inverted cup shape. The cylindrical side wall portion extends into and engages the side wall of the recess 2 and the head end 3*, which is rounded, is positioned beyond the outer end of the nozzle member 2. This rounded end has a plurality of diverging orifices 3 for spraying the contents of the container as they are forced outwardly by the compression of the bulb or the bulbous container I.
When the nozzle member 2 is removed, a relatively large opening is provided in the container When the nozzle member is screwed into position, compression of the bulbous container will cause the powder to be discharged through the tubular portion 2* and dispersed, spread, or dusted from the nozzle tip 3. The constricted inner end 2 causes a limited amount of powder to be blown from the container, and is immediately allowed to spread or be suspended in the air also blown therefrom. It is further spread or expanded when discharged through the orifices 3 When desiring to use the article as a syringe, the nozzle member is merely reversed, with the tubular portion 2 directed outwardly, as indicated by dotted lines in Fig. 1. In such condition, water or other liquid within the bulbous container may be forced in the direction desired.
In the modified form shown in Fig. 2, the nozzle member, designated 4, is shown as being mere- 1y pressed within the opening I of the bulbous container and is held therein by an annular ridge N. In this modification, the outer end of the nozzle member is axially extended, as indicated by 4 providing an extended powder spreading,
reduced aperture communicating with the interior of the container, said nozzle being further provided with a spraying head at its outer extremity, the diameter of said passage being progressively increased outwardly of said neck portion, whereby fluent material dispensed through said passage will disperse therein prior to discharge.
9. A collapsible container as described in claim 7 where said reduced aperture is disposed transversely of said passage at the inner extremity thereof.
10. A collapsible container as described in claim 8 where said reduced aperture is disposed transversely of said passage at the inner extremity thereof.
11. A collapsible container adapted to receive fluent material to be dispensed therefrom, said container having a portion provided with an aperture therein, a nozzle member disposed in said aperture, means for retaining said nozzle in said aperture, said nozzle being provided with a longitudinal passage communicating with the interior of the container and providing means for restricting the quantity of fluent material dispensed from said container, said nozzle being further provided with a spraying head at its outer extremity, and means for dispersing fluent material within said spraying head prior to discharge therefrom.
