Application June 16, 1955, Serial No. 515,827
6 Claims. (Cl. 222-212) This invention relates to a dispenser, and more particularly to a package for holding and dispensing a quantity of powder like material.
The object of the invention is to provide a dispenser which is adapted to be used for manually dispensing a quantity of powder like material, there being a means for preventing accidental discharge of the material from the package.
Another object of the invention is to provide a dispensing package whereby powder can be readily manually dispensed or discharged in the form of a spray when desired, and wherein the discharge opening in the package can be readily sealed off to prevent accidental dispensing or discharge of the powder.
A further object of the invention is to provide a powder dispenser which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
Figure 1 is an elevational view illustrating the powder dispenser of the present invention being used.
Figure 2 is an elevational view illustrating the dispenser turned around and with the discharge opening sealed off as when powder is not being dispensed.
Figure 3 is a sectional view taken on the line 3-3 of Figure 2.
Figure 4 is a fragmentary elevational view illustrating the bracket or clamp in place for sealing off the container.
Figure 5 is a plan view, with parts broken away and in section, illustrating a modified spring member for urging the sections or body members apart.
Figure 6 is a sectional view taken on the line 66 of Figure 5.
Figure 7 is a sectional view taken on the line 7-7 of Figure 1.
Figure 8 is a view similar to Figure 7 but showing the plug in closed position.
Figure 9 is a sectional view taken. on the line 9-9 of Figure 2.
Referring in detail to the drawings, the numeral 10 designates a package or container which is adapted to be made of flexible transparent material such as cellophane or other suitable transparent plastics, and the container 10 includes a pair of wall members or body members 11 of rectangular shape. The container 10 is adapted to hold a quantity of powder 12 which is to be dispensed, and the powder 12 may be of any desired composition. The outer edge portions 14 of the wall members 11 are secured together by any suitable means, as for example by means of an adhesive or glue.
A means is provided for biasing or normally urging the wall members 11 away from each other as shown in Figure 3, and this means comprises in Figures 1, 2 and 3 a cylindrical or coil spring 15 which is interposed between the central portions of the wall members 11. How- "ice ever, by manually applying pressure to the package as shown in Figure 1, the spring 15 will be compressed so that the powder 12 will be dispensed or discharged through an opening 17 in the corner of the package 10.
A corner of the container 10 is cut away as at 16 adjacent the discharge opening 17. A closure plug 18 which is wedge shaped is provided, and the closure plug 18 may be made of sponge or foam rubber or the like.
Secured to the plug 18 and arranged exteriorly of the container 10 is a bracket 19. The bracket 19 may be made of a single piece of wire and includes a twisted portion 20 which has a pair of curved arms 21 extending therefrom. A corner portion 22 of the container 10 is adapted to be folded over as shown in Figures 2 and 4 when the powder 12 is not being dispensed, and the arms 21 are adapted to coact with the twisted portion 20 to clamp the folded portion 22 therebetween whereby the powder will not accidentally spill from the container. Referring to Figures 5 and 6 of the drawings there is shown a modified resilient means for urging the wall members 11 outwardly or away from each other, and
this resilient means comprises a coil spring 23 which is arranged in an elliptical formation. The spring 23 may have an eye 24 on one end for engagement with a hook 25 on the other end of the spring.
From the foregoing it is apparent that there has been provided a dispenser which is especially suitable for use in dispensing powder like material such as the material 12. In use, the container 10 may be filled with the powder by any suitable means, and when the powder 12 is not being dispensed the parts are in the position shown in Figure 2. Thus, with the parts as shown in Figure 2 the portion 22 is folded over and the. arms 21 are bent over the opposite side of the folded over portion from the twisted portion 20 whereby a clamp is provided which retains the end of the container sealed oft. At the same time the wedge like plug 18 helps prevent any flow of powder through the opening 17. When it is desired to dispense the powder, it is only necessary to disengage the bracket or clamp 19 from the folded. over portion and then move the parts to thevposition shown in Figure 1..
Then, by applying manual or finger pressure on the wall members 11, the spring 15 can be compressed back and forth alternately so that the powder 12 will be dispensed out past the plug 18 through the opening 17 in the form of a fine powdery like spray. As soon as pressure on the spring 15 is released the walls 11 will move away from each other so that by quickly compressing and releasing the spring 15 the powder 12 can be dispensed. Instead of using the cylindrical coil spring 15, the spring member 23 can be used as shown in Figures 5 and 6.
With the spring 23 arranged as shown in Figures 5 and 6, pressure can be applied to any part of the package to dispense the powder. The dispenser of the present invention can be oscillated with one hand so that the other hand is free to do other tasks. The dust is dispensed in a controlled amount in the desired direction and the device can be made in any desired size and shape and out of any suitable material. The bracket 19 also serves as a handle for moving the plug 18 into and out of closing relation with respect to the opening 17. The plug 18 prevents the contents from accidentally spilling out of the container when the container is turned upside down, but the parts are constructed so that sufficient air can enter the interior of the container as the powder is dispensed from the container. Instead of using a spring in the center of the container for causing the walls to flex outwardly, any suitable resilient means can be used. The transparent wall members 11 permit the user to readily observe the quantity of material in the container.
Formed integral with the bracket 19 is an enlarged portion or eye 26. The eye portion 26 is of a size so 3 that the plug 18will be maintained immobile in its various adjusted positions. Thus, with the device in closed position as shown in Figure 118, the eye portion 26 is arranged exteriorly of the container 10. With the dispenser in open position as shown in Figures 1 and '7, the eye portion 26 is pushed through the .discharge opening .17 so that it is arranged interiorly ,or within the container so that the plug 18 is maintained away from the opening 17 whereby the contents "12 can be readily dispensed through the opening 17. The eye portion 2e is of a size that it can move through the opening 17.
Thus, the eye portion 26 holds the plug .18 in its open position when desired and also holds the plug in its closed position when desired, but by applying manual pressure to the bracket 19, the eye portion can'be moved through the discharge opening '17. With the plug 18 in the position shown in .Figure 1 the powder '12 will be readily able to pass around the plug '18 and out through the opening 17. The eye portion 26 maybe formed in the twisted section 20 of the bracket 19. As shown in Figure 2, the package is sealed oil when not being used so that a .double seal is formed whereby the contents are maintained airtight so that no moisture can enter the interior of the package to dampen the powder '12 when the bracket 19 is placed over the folded portion 22. The outer edge portions 14 of the device can be sealed together in any suitable manner, as for example by means of an adhesive or glue or by means of heat sealing.
