8 Claims.

This invention relates to a dispenser adapted to support a conventionally designed collapsible container, the dispenser constituting the present invention being so designed as to apply pressure against the container tending to collapse the same, under the control of a user.

Heretofore, dispensers for containers of the collapsible type have been devised, which dispensers apply squeezing pressure to the collapsible containers supported thereby, tending to reduce the interior cross sectional area of the containers and thereby bring about evacuation of the container contents. However, to my knowledge, there has not previously been devised a dispenser of this type which will initiate the containersqueezing action responsive to swinging of an operating lever by an object such as a toothbrush, when said object is positioned below the discharge end of the container at a location in which said object will receive the ejected container contents, ;2

with the operating lever transmitting pressure to a container-engaging pressure plate member through the medium of a self-adjusting yoke assembly that gravitates freely upon the plate member to a proper position determined by the extent of evacuation of the container contents.

The main object of the present invention is to provide an improved dispenser having the characteristics noted above. In this connection, it is believed important to note that by causing the a container contents to be dispensed through the medium of an operating lever, a freely gravitating, self-adjusting yoke assembly, and a swinging pressure plate member as discussed above, I propose to accomplish uniform ejection of the container contents regardless of the amount of material remaining within the container, without substantially varying swinging movement of the operating lever or the pressure which must exerted against the operating lever by the lever engaging object.

A. further object of importance is to provide a dispenser as described in which a stationary base plate and a pressure plate member will be pivotally connected to one another in such a manner as to cause the same to diverge in a direction away from the pivotal connection, the base plate being adapted to support a collapsible container in a position in which the container will be interposed between the diverging base plate and pressure plate member, said base plate and. pressure plate member being specifically designed, at their divergent ends, to squeeze the container transversely while holding deformation of the head part of the container to a minimum.

Yet another object is to provide a device as stated in which the pressure plate member and the base plate will each be provided with a longitudinal series of complementary recesses, said recesses being so designed as to engage the foot end of a supported container. It is proposed, in this connection, to so space the recesses longitudinally of the plate member and base plate as to permit the device to be efficiently used with collapsible containers of difierent sizes.

Yet another object is to provide a means for swinging the pressure plate member toward the base plate which will comprise a self-adjusting yoke assembly that gravitates downwardly upon the pressure plate member, to adjusted positions that will be determined proportionately to the angle of divergence of the plate member and base plate. In this way, it is proposed that the yoke assembly associated with the pressure plate member will remain in engagement with said plate member at all times, regardless of the extent to which the plate member will have been swung inwardly toward the base plate as the container contents are exhausted. It is further proposed to associate with said yoke assembly an operating lever and a double-throw crank, the lever and crank being so arranged as to cause a small amount of swinging movement of the operating lever to'be translated into a cam action exerted by one throw of the crank against the base plate, tending to shift the yoke assembly transversely of the base plate and the pressure plate member. A controlled, uniform pressure is thus applied against the plate member regardless of the position to which the plate member is swung toward the base plate, and regardless of the extent to which the yoke assembly has gravitated downwardly therealong.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawings, in which like reference characters designate like parts throughout the several views, and wherein:

Figure l is a perspective view of a dispenser formed in accordance with the present invention;

Figure 2 is a front elevational view, a collapsible container being shown in proper position for dispensing of the contents thereof;

Figure 3 is a top plan view;

Figure 4 is a longitudinal sectional view on line i-t of Figure 2, a toothbrush being illustrated in dotted lines in a position in which said brush is disposed preliminary to actuation of the lever engaged thereby;

Figure 5 is a view similar to Figure 4, the lever a being swung outwardly, the dotted lines indicating other positions of the lever assumed thereby during the dispensing operation;

Figure 6 is a sectional view on line 6 of Figure 4; and

Figure 7 is an enlarged transverse sectional view on line 1-1 of Figure 2.

Referring to the drawings in detail, the reference numeral 10 has been applied generally to a stationary support assembly. Said support assembly is adapted to be fixedly mounted upon any suitable surface, such as a room wall. The assembly I6 includes a vertically disposed, fiat back plate l2, said back plate being integrally formed, at its lower end, with rearwardly extended bracket members I4 terminating, at their rear ends, in outwardly extended ears I 6. Ears Hi are each formed with spaced apertures adapted to receive screws or other fastening elements, not shown, whereby the device can be fixedly mounted upon the wall surface. It will be readily appreciated that when the support assembly i0 is mounted upon the wall surface, the base plate I 2 will be spaced forwardly a short distance from said wall surface.

Integrally formed upon the lower end edge of the base plate 12 is a pair of forwardly projected support ledges l8. Ledges It are horizontally disposed, and have spaced apart, beveled inner edges 20. The inner edges merge, at their rear ends, with the opposite ends of the edge of a relatively wide clearance opening 22 formed in the lower end portion of the base plate I2.

Disposed medially between opposite ends of the opening 22 is a lip 24, formed upon the back plate 12 for the purpose of reducing deformation of the head part of a collapsible container, in a manner to be presently made apparent.

At its upper end, the base plate [2 is formed with slits extending inwardly from its opposite side edges, and the portions defined between said slits and the upper end edge of the base plate [2 are extended rearwardly to form bearing lugs 25. The bearing lugs 26 are apertured to receive the opposite ends of a pivot pin 28, said pivot pin extending rearwardly of the base plate at the upper end thereof.

A pressure plate assembly has been designated generally by the reference numeral 32, and includes a pressure plate member 32. The plate member 32 is coextensive in width with the base plate !2, but is slightly shorter in length than the base plate, thus to cause the lower end edge of the pressure plate member to be spaced upwardly from the support ledges it of the base plate.

At its upper end, the pressure plate member is slit inwardly from the opposite sides thereof, and the portions defined above said slits are extended rearwardly to provide ears 34. The ears 34 are apertured for extension of the pivot in 28 therethrough, and thus, it is seen that the plate member 32 is pivotally connected at its upper end to the base plate l2, for swinging of the free or lower end of said plate member toward and away from the lower end portion of the base plate.

The lower end edge of the plate member 32 is of arcuate formation, in the preferred embodiment of the invention, as best shown in Figures 1 and 2. It has been found that this particular shape of the lower end edge facilitates the transverse squeezing of the collapsible container, while holding deformation of the head part of the container to a minimum.

Disposed medially between the opposite side edges of the pressure plate member 32, and formed upon said arcuate lower end edge thereof, is a lip 36, which lip desirably thickens the pressure plate member at the particular location at which the head part 38 of a collapsible container- 46 would normally curl upwardly when the body 42 of said container has been squeezed almost to its full extent.

It will thus be seen (see Figures 4 and 5) that initially, the head part 38 of the container will be disposed below the lower end edge of the plate member 32, and below the upper edge of the clearance opening 22 of the base plate. As a result, swinging of the plate member 32 toward the base plate 12 will be effective to squeeze the body 42 of the container, while not squeezing the head part 38 correspondingly. Ordinarily, squeezing of the body 42 would tend to curl diametrically opposite portions of the head part upwardly, but the enlargements defined by lips 2 36 resist the upward curling of said diametrically oppositeportions of the head part, thereby to control the deforming of the head part during the reduction of the container to a completely exhausted state.

It may be noted that when the container 40 is inverted and positioned against the base plate I2, the neck of the container will extend downwardly within the space between the support ledges 18, the beveled inner edges 20 of said support ledges complementing the generally tapered or conical formation of the head part 38 (see Figure 2).

I provide, in my dispenser, means for accommodating the same to collapsible containers of different sizes. Accordingly, the inner surface of the plate member 32 is formed with a longitudinal series of shallow, transversely extending recesses .46. The recesses 48 are spaced equal distances apart, longitudinally of the plate member 32, and extend fully from side to side of the plate member. In the opposing surface of the base plate .12, a longitudinal series of shallow, transversely extending recesses 48 is provided, the several recesses 48 being paired with corresponding recesses 46 of the plate member 32.

The recesses 45, 42 are provided for engagement th rein of the bottom flange or clamp 44, generally provided at the foot end of a collapsible container of the type illustrated. It is desirable, in this connection, that said recesses be provided, since the clamp or flange 44 defines a thickened portion at the foot end of the container, which thickened portion would ordinarily prevent the container from being squeezed fiat. Since the recesses 48, 48 are arranged in pairs spaced longitudinally of the plate member 32 and base plate l2, it will be obvious that containers of different lengths can be readily accommodated in the dispenser constituting the present invention.

The device also includes a yoke assembly designated generally by the reference numeral 56. In this connection, the yoke assembly 50 is circumposed about the pressure plate member 32 and the base plate [2, and is slidable longitudinally of these parts, the yoke assembly gravitating freely therealong, responsive to the changing angle of divergence of the member 32 and base plate E2.

The yoke assembly 5 3 includes a yoke 52, the yoke 52 being formed substantially to a U shape, and having its bight extending transversely of and overlying the outer surface of the plate member 32. The arms of the yoke embrace between them the plate member and the base plate l2,

as best shown in Figure 7, and the free end portions of said arms are projected rearwardly for a short distance beyond the rear surface of the base plate [2.

Formed in the free ends of the yoke arms are bearing openings, in which are journaled the opposite end portions 54 of a double-throw crank designated generally at 56. The crank 56 has been illustrated to its best advantage in Figures 4-6, and as will be noted, said double-throw crank includes a relatively short throw 58, merging into a long throw 60. Thus, the bight portion of the short throw 58 is spaced outwardly a relatively short distance from the axis of rotation of the crank, the bight portion of the throw 60 being spaced a substantially greater distance away from said axis of rotation.

It is also important to note that in the preferred commercial embodiment of the invention, the throw 58 lies in a plane disposed at a wide obtuse angle to the plane in which the throw 69 lies (see Figure 4).

It will be seen that with throw 60 depending vertically in spaced relation to the back surface of the base plate l2, swinging movement of the throw 66 away from the base plate, that is, in a counter-clockwise direction when the throw $0 is viewed as in Figures 4 and 5, will be efiective to swing the short throw 58 inwardly into engagement with the back surface of the base plate l2. As a result, the entire yoke assembly 50 will be biased to the right in Figure 4, thus to cause pressure to be exerted against the plate member 32 tending to swing said plate member inwardly toward the base plate !2.

I provide means actuated by the object onto which the container contents are to be dispensed, that is adapted to impart said swinging movement to the long throw 553 of, the crank 56. Said crank rotating means has been designated generally by the reference numeral 62, and includes an elongated operating lever 64. Lever 554, as will be readily noted from Figure 4, is substantially greater in length than the length of the base plate I2, so as to cause the lower end of said lever to project below the lower end of the base plate.

At its upper end, the lever 54 is formed with a transversely extended bearing sleeve 6% (Figure 6) through which the pivot pin extends. In this way, the lever 84 is swingably connected, at its upper end, to the upper end of the base plate it. thus to permit the lever 64 to swing between the full and dotted line positions shown in Figure 5.

- At its lower end, the lever 64 is formed with I a laterally projecting, flat, enlargement 6B, having a recess Hi in which is engageable the tip of a lever-actuating object such as a conventional toothbrush 12.

It will thus be seen that if the brush or other object 12- is shifted to the right in Figures 4 and 5, the lever 6.! will be swung from its normal position shown in Figure 4 to the full or chaindotted positions shown in Figure 5. In other words, if it is desired that a relatively small amount be dispensed from the container, the lever could be urged rearwardly to the full line position shown in Figure 5. If, however, a longer ribbon. is desired, the lever could be swung to the chain-dotted position shown at the right in Figure 5.

In any event, when the lever is being swung rearwardly, the brush may be inclined as shown in full lines in Figure 5. As a result, when the lever 64 has been swung rearwardly, the ribbon dispensed from the container will extend downwardly from the discharge end of the container. so as to overlie the midlength or inner end portion of the bristle part of the brush, the portion toward which said ribbon extends depending, of course, upon the extent to which the lever 64 is swung rearwardly.

Thereafter, the brush may be tipped upwardly, pivoting about the point of its engagement with the lever 64, so as to cause the lower end of the dispensed ribbon to impinge against the bristles of the brush. The brush can then be pulled away from the lever 64, and will cause the rib bon to arrange itself longitudinally of the brush.-

It may be noted that the arcuate formation of the end edge of the plate member 32, and the arcuate formation of the intermediate edge portion of the opening 22 is designed to prevent tearing of the wall of the container, where said edges engage the container wall. It has been found by experimentation that the arcuate edge formation will elim' to such tearing, as distinguished from straight edges, which tend to tear the material of which the container is formed.

Further, it is to be noted that the particular formation and arrangement of the lips 24, 35, while preventing undesirable deformation of the head part 38 of the container, will, after the container has been substantially exhausted of contents, control the upward curling of the diametrically opposite portions of said head part. thus to eventually cause the head part to be collapsed to an extent efiective to make use of the full amount of the container contents.

or course, the device is adapted not only for use in association with toothpaste containers, but also is adapted to control the dispensing of shaving cream, cream shampoo, and other ma terial of a pastelike or cream-like consistency that is ordinarily dispensed from collapsible tubes.

It is also important to note that the particular construction which I have devised is such as to cause the pressure exerted against the plate member 32 to be maintained uniformly, regardless of the extent to which the plate member 32 is swung inwardly toward the base plate 12. In other words, the angle of divergence of the plate member 32- and base plate i2 will, of course change according to the extent to which the container contents are dispensed. As said angle of divergence changes, the yoke assembly will adjust itself to the changing angle, the yoke" assembly gravitating freely upon the'plate momber 32 and base plate IL. At all times, of course, the crank and the lever remain in the normal position shown in Figure this being true without regard to the location to which the yoke assembly adjusts itself longitudinally of the device. Therefore, the extent of throw of the lever at, under pressure of object 12, remains unchanged at all times, and the pressure exerted against the plate member 32 correspondingly remains substantially unchanged. Controlled dispensing of the container contents is thus assured, whether the container is full, or practically exhausted.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to .be necessarily limited to the specific construction illustrated and described. since such construction is only in the brush or other tended to be illustrative oi the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
