- Nov. 19, 1968 J. GOULD DEFORMABLE PLASTIC DISPENSER Original Filed May 20, 1965 l/VVd'A/TOL: Jerome 6011/1 United States Patent 3,411,674 DEFORMABLE PLASTIC DISPENSER Jerome Gould, Encino, Calif., assignor to Design Properties, Inc., Los Angeles, Calif., a corporation of California Continuation of application Ser. No. 457,347, May 20, 1965. This application Mar. 1, 1967, Ser. No. 619,871 8 Claims. (Cl. 222215) ABSTRACT OF THE DISCLOSURE This invention relates to a seasoning dispenser which is formed from a pair of oppositely disposed rigid ends and a corrugated body between the ends. Holes are provided in one of the ends to dispense the seasoning. The dispenser is operated by pressing the corrugated portion. This causes the body portion to become collapsed on the corrugations and the opposite end portions to become rotated in opposite directions without deforming the end portions and without changing the distance between the end portions.

This application is a continuation of Ser. No. 457,347, filed May 20, 1965, now abandoned.

This application relates to a plastic dispenser. More specifically, this application relates to a deformable plastic dispenser so constructed that a compressive force on the dispenser reduces the volume within the dispenser so as to dispense a portion of the contents of the dispenser through an opening in one end wall of the dispenser.

The dispenser of the present invention is compressed by encircling the dispenser with one hand and squeezing the dispenser, using a normal gripping motion. With the novel construction of the dispenser, large rapid changes in volume of the dispenser follow the squeezing. Also, as the dispenser is squeezed, not only is the volume within the dispenser reduced, but opposite ends of the dispenser rotate in opposite directions to provide twisting motions in the dispenser. Since the dispenser is operated with one hand, and since the operator uses the entire hand rather than just the fingers, the dispenser when being operated has a natural feel in the hand. Also, it is possible to apply much more pressure through the gripping motion of the hand rather than using only fingers. The plastic dispenser of the present invention also has a very pleasing, attractive and distinctive shape.

The deformable plastic dispenser of the present invention substantially takes the shape of a cylinder. In the particular embodiments described in this application, the dispensensubstantially takes the shape of a right circular cylinder. The cylindrical wall, however, is formed of corrugated material. More specifically, the corrugations in the wall run in a diagonal direction from one end of the cylinder to the other. The ends of the dispenser are formed as rigid end walls. In a first embodiment of the invention, the end walls are flat, and holes are provided in one end wall so that a portion of the contents of the dispenser can be ejected from the dispenser through the holes to the outside. In a second embodiment of the invention, one end wall of the dispenser has a domed portion with a plurality of holes in the domed portion. This allows for greater dispersion of the contents of the dispenser. Also, one end wall of the dispenser can be formed to have a small nozzle with a very small hole so that the end wall acts as a spray nozzle. Another adaptation of the deformable plastic dispenser is to have one end wall contain a removable portion to allow for a refilling of the dispenser. Y

The deformable plastic dispenser of the present inven- 3,41 1,674 Patented Nov. 19, 1968 tion can be used for liquid materials, such as deodorants or shampoo, or could be used for dry materials, for example, talcum powder. The invention will become clearer with reference to the following drawings wherein:

FIGURE 1 illustrates a first embodiment of the invention;

FIGURE 2 illustrates the operation of the invention, specifically with reference to the structure of the first embodiment shown in FIGURE 1;

FIGURE 3 illustrates a modification of the invention using a domed top;

FIGURE 4 illustrates another modification of the invention using a spray nozzle top; and

FIGURE 5 illustrates a refillable dispenser.

In FIGURE 1 a plastic dispenser 10 substantially has the shape of a right circular cylinder. The cylindrical wall is formed of a series of upwardly extending parallel ridges having side walls 12 and 14. End walls 16 and 18 are connected and sealed to the cylinder. As shown in FIG- URE 1, the end walls are flat. Holes 20 are placed in one end wall to allow the ejection of the contents of the dispenser. The dispenser is made of a tough, flexible plastic material which allows the flexing of the cylindrical wall but provides sulficient restoring force so that the dispenser will return to its original shape.

FIGURE 2 illustrates the operation of the deformable plastic dispenser of the present invention. As can be seen in FIGURE 2, the dispenser 10 is gripped in a position intermediate the end walls by the user. The dispenser 10 is then squeezed, using a normal gripping motion of the hand, to collapse the corrugations or ridges formed in the cylindrical wall of the dispenser. The side walls 12 and 14 of the ridges are compressed toward each other so that the normal volume of the dispenser is reduced. In addition, the compression of the dispenser produces rotation at the outer ends of the cylinder. More specifically, the upper portion of the cylinder rotates in a direction as shown by arrow 22 and the lower end of the cylinder rotates in an opposite direction as shown by arrow 24. The double rotation of the dispenser is helpful when the dispenser is used to eject dry materials such as powders, since the double rotation loosens the powders within the dispenser and prevents the powder from becoming caked in a single position. As the container is operated as shown in FIGURE 2, a portion of the contents of the container is ejected through the holes 20 in an upward! direction as shown by the lines 26, due to the rapid reduction in the internal volume of the dispenser.

In FIGURE 3 a modification of the upper end wall of the plastic dispenser is shown which uses a domed top 100. The domed top also provides a rigid end wall and includes holes 102 disposed through the domed top. The contents of the dispenser are ejected as shown by lines 104. As can be seen in FIGURE 3, the contents of the dispenser are dispersed over a much broader area than from the dispenser of FIGURE 1.

FIGURE 4 illustrates another modification of the dispenser and shows an upper portion which has a spray nozzle 200 attached to one of the rigid end walls. This type of dispenser would be used to dispense liquid materials such as deodorants. A small hole 202 extends through the nozzle 200. As the dispenser is squeezed, the liquid material is forced through the small hole 202 and forms a spray, as shown at 204. It will be appreciated that the hole 202 may be made larger so as to allow for the dispensing of heavier liquids, such as shampoos, in a steady stream.

FIGURE 5 illustrates the dispenser constructed in accordance with the invention using a plug 300 inserted in the bottom end wall. The plug 300 is designed to be removable. For example, the plug can be screwed into the bottom portion or can snap into the bottom portion. The use of the plug 300 allows the deformable plastic dispenser to be refillable and, therefore, reusable.

Since the deformable plastic dispenser of the present invention is formed of a substantially circular cylindrical shape, it can be very easily grasped in one hand. It is, therefore, not necessary to use two hands, or to use only the fingers to operate the dispenser. Also, since the dispenser is formed with diagonally disposed corrugations or ridges, a good surface is provided for gripping the dispenser, and the dispenser will not easily slip from the hand of the user. In addition, since the dispenser does have a good surface for gripping, it is possible for the user to exert very strong pressure on the dispenser, and since the collapsible corrugations or ridges allow for considerable reduction in volume, the contents of the dispenser can be ejected very easily. The deformable plastic dispenser has been illustrated with reference to particular embodiments, but it is to be appreciated that other adaptations and modifications may be made. Therefore, the in vention is only to be limited to the appended claims.
