4 Claims. (Cl. 222-103) Our present invention relates to supporting devices and more particularly to a device for supporting a collapsible tube such as is commonly used for dispensing tooth paste, shaving creams, and the like.

An object of our invention is to provide a simple, inexpensive and practical supporting means by which a collapsible tube of tooth paste or like commodity may be mounted` upon a wall where its contents may be extruded in a convenient lo Figure 3 is a vertical sectional view taken cenmarmer without removal from the support. trally along line III- III of Figure l looking in Another object of the invention is to provide direction of arrows, a new and novel form of support which may be Figure 4 is a fragmentary sectional view similar attached to the wall of a washroom for holding to Figure 3 showing the parts in another operaa collapsible tube and in which a novel extruding l5 tive position, and mechanism is employed to extrude measured Figure 5 is a fragmentary view taken at the quantities of a commodity in a simple and effecbottom of Figure l, showing the spring clip artive manner. rangement employed for gripping the discharge Another object of the invention is to provide end of a collapsible tube. a collapsible tube discharging means upon a wall Upon referring to the accormoanying` drawing it` mounted support by which the contents of a will be noted that our improved collapsible tube collapsible tube may be extruded with a kneading supporting device comprises two main cooperataction to thus insure against a caking or hardening portions; namely, a base or back portion I0 ing of the contents of the tube at the closed end which is adapted to be hung upon a wall or other thereof. suitable support and a vertically movable car- We are aware that many attempts have been rias@ Il having means, aS Will be presently BX- made to provide a practical support for tooth plained, by which the upper end of a commodity paste and like collapsible dispensing containers dispensing collapsible tube l2 may be compressed. but so far as we are aware none of these devices As here shown. the back or base portion IU has have come into any extensive use. The need for vertically extending side flanges I3 and M which such a device is generally due to a desire to have extend outwardly at the front thereof. Along the the particular commodity, whether it be tooth inner surfaces of these vertically extending paste or shaving cream, in a convenient location iianges I3 and ifi there is a groove that forms unwhere its contents may be extruded without endercut traclrways i5 into which outwardly distaillng messy operation or injury to the tube posed lips IB at eachside of the movable carriage as so often happens when these tubes are rolled il extend. In this manner the carriage I I is free by hand. There is also the further difficulty that to move vertically along the base or back portion as these tubes become more collapsed and citen Ill when the latter is secured against a wall or distorted they require some special form of reother surface. As a means for suspending the pository. ln practice when squeezed by hand 4G base or back portion I0 upon a wall or other surthe contents of these tubes often become depositface there is a keyhole slot I'I through which a ed on the outside of the tube and therefore the nail or screw may extend. At its lower end the matter of placing them away in a medicine cabibase or back portion IIJ has a horizontally disnet becomes objectionable and as a consequence posed and outwardly extending flange or boss I 8 these tubes in various degrees of discharge are which carries a spring clip I9 that is adapted to more often found laying on the wash bowl wherev engage with the neck of the collapsible tube I2 bethcy present an untidy appearance. It is theretween its shoulder 2l] and a cap 2l at` the end fore a further object of our invention to provide thereof. At its other end, as is more clearly shown a full and complete support for a Collapsible tube in Figure 3 of the drawing, the collapsible tube l2 commodity from which its contents may be exis gripped at its closed end between two eccentritruded in a simple, convenient and neat manner cally mounted substantially cylindrical surfaces and winch will overcome the above objectionable 22 and 23 which when rocked with respect to features. each other will produce a squeezing or kneading Other objects and advantages of our invenaction alternately upon the opposite sides of tion will be in part evident to those skilled in the the tube I2. In this particular showing the ecart and in part pointed out in connection with the accompanying drawing, wherein there is shown by way of illustration and not of limitation a preferred embodiment of the invention.

In the drawing;

Figure 1 is a front view of our improved device,

Figure 2 is a plan view of our device with the base portion sectionalized along line II-II of Figure l,

der the influence of a biasing spring 29 which is looped around the shaft 23. In order to limit this outward swinging movement of the arcuate members 2t there is provided oppositely disposed arcuate slots 3@ in the side p-lates 2d and 25 of the movable carriage and into which the ends of a transversely extending pin 3l' project. At this point it will be noted that the arcuate member 2t upon which thD cylindrical surface 22 is formed is mounted closely adjacent the back or base portion Ill of the device and where it will be engaged by one side of the collapsible tube I2 when held by the neck engaging spring clip i9. In this position the arcuate member 2t with its cylindrical surface 22 will operate as a rocking anvil against which the collapsible tube I2 will be squeezed when the arcuate surface 23 is operated to extrude the contents of the tube I2. In this instance the arcuate surface 23 is shown as formed upon a lever-like member 252 which is pivotally mounted in spaced relation with the arcuate or anvil forming member 2t by means of a shaft 33 that extends through the side plates 2li and 25 of the carriage II. This in effect forms what may be termed a cam-like hub portion upon the lever-like member 32 which will exert a rolling pressure upon the tube I2 when the lever-like member 32 is operated downward.

With the above arrangement and with particular reference to Figure 3 of the drawing it will be seen that when the collapsible tube I2 is engaged at its neck by the spring clip I9 and with its closed end disposed between the substantially cylindrical surfaces 22 and 2d formed respectively upon the arcuate member 25 and the lever 32, a downward movement of the lever 32 will cause the eccentrically disposed cylindrical surface 23 to roll downwardly in kneading fashion against the outside of the tube I2. At the same time the surface 22 upon the member 2G will yield with a somewhat contrary rolling action, as is more Clearly illustrated in Figure i of the drawing, and as a result the contents of the tube I2 will be forced downwardly and extruded at the neck thereof. Under these conditions the cap 2l of the tube will be removed and by holding a tooth or shaving brush or the hand therebelow the extruded commodity may be conveniently collected. In this operation it will be understood that the amount of the commodity extruded during any one operation will be determined by the amount of movement imparted to the hand operated lever 32. Under normal operating conditions it is contemplated that only a Very slight movement of the lever 32 will be found sufficient and as each desired quantity of the commodity is extruded the lever will be released and returned to its uppermost position. During this particular backward movement .of the lever 32 the yieldingly supported anvil-like cylindrical surface 22 will again rock or swing outwardly against the tube I2 and cause the side of the tube I2 engaged thereby to be compressed a further amount to compensate for and equalize the deformation caused by the previous operation of the lever 32. Operating in this manner it will be seen that as the contents ISO of the collapsible tube I2 is discharged its closed or bottom end will become flattened. This will permit the movable carriage II to travel downwardly in the trackway I5 formed in the sides I4 of the back or base portion I0 until the tube I2 has become completely empty. An advantage of this arrangement is that by providing the rocking anvil-like surface 22 which engages one side of the tube I2 and the eccentrically mounted cylindrical surface 23 which engages the other side of the tube I2 there is effected a squeezing action that will be alternately applied to the opposite sides of the tube I2. In other words the contents of the tube may be said to be kneaded rather than squeezed out of the tube. Another advantage of this arrangement is that the contents of the tube will be more effectively extruded from the tube and with less danger of breaking the tube than is the case where the tube is compressed by two oppositely disposed rollers as has been proposed in many prior art devices produced for this purpose.

The particular device here described and illustrated in the accompanying drawing is constructed entirely of transparent plastic material which is cut, bent or rolled into the shapes desired from sheets and then cemented together by the use of a suitable adhesive. The spring 39 and the spring clip I9 are of course of spring steel. When constructed of this material in the manner shown the device with the tube I2 mounted therein presents a decidedly ornamental appearance which will further encourage its use in an exposed position upon the wall of a washroom.

While we have, for the sake of clearness and in order to disclose the invention so that the same can be readily understood, described and illustrated a specific form and arrangement, we desire to have it understood that this invention is not limited to the specific form disclosed, but may be embodied in other ways that will suggest themselves to persons skilled in the art. It is believed that this invention is new and all such changes as come within the scope of the appended claims are to be considered as part of this invention.
