ATTORNEY United States Patent O 3,203,596 HOLDER AND DISPENSER FOR COLLAPSIBLE T BE Isaac F. Davidson, 15404 SE. Wallace Road, Portland, Oreg. Filed June 1, 1964, Ser. No. 371,390 4 Claims. (Cl. 222-103) This invention relates in general to dispensing means for containers comprising collapsible tubes, and relates' more particularly to dispensers for the conventional collapsible tubes used as containers for toothpaste, shaving cream, and the like.

An object of the invention is to provide an improved and simplified holder and dispenser for such collapsible tube which, when in normal inoperative position, will hold the tube firmly, and which, when operated in one direction, will cause a desired amount of the tube contents to be discharged through the outlet neck of the tube, but which, when operated in the other direction, will enable the position of the tube in the device to be adjusted to compensate for the withdrawal of the contents from the .tube or enable the tube to be removed entirely from the device.

A related further object of the invention is to provide a novel holder and dispenser of very simple construction for such a collapsible tube which can be operated with one hand by the user, and which will include a special lever assembly, enabling the contents of the tube to be squeezed out from the neck of the tube as desired, and also enabling the position of the tube to be shifted in the device when required, when linger pressure is exerted upon the lever assembly.

A further object is to provide a practical and simplified holder and dispenser for collapsible tubes which can be produced very inexpensively and thus meet a market demand for such dispensers which other more complicated and more expensive devices of a similar nature have failed to satisfy.

The manner in which the improved and simplified holder and dispenser of the present invention is constructed and operated will be briey described with reference to the accompanying drawings, wherein:

FIG. l is a side elevation of the holder and dispenser showing a partially emptied toothpaste tube being held in the same, the device being in the normal tube-holding position;

FIG. 2 is a plan view taken on line 2-2 of FIG. l;

FIG. 3 is a sectional elevation taken on line 3*-3 of FIG. 1 drawn to a larger scale;

FIG. 4 is a fragmentary sectional elevation, similar in part to FIG. 3 but showing the device being operated to dispense toothpaste from the tube;

FIG. 5 is a similar fragmentary sectional elevation but showing the device being operated for enabling the position of the tube to be shifted on the device; and

FIG. 6 is a transverse section on the line indicated at 6-6 of FIG. 5.

In the figures the collapsible tube is indicated by the reference character T, the tube being of well-known shape and construction, such as an ordinary toothpase tube, for example, and thus needing no further description.

The holder and dispenser includes a base plate 10 of metal or plastic or any other suitably rigid material. A substantially trough-shaped operating lever assembly, indicated in general by the reference character 11, is hingedly or rockably mounted on the base plate and includes a pressure plate 12, extending forwardly and upwardly from the bottom portion of the lever assembly, and in integral lifting lever plate 13, extending rearwardly and upwardly from the bottom portion of the assembly, and a pair of

side brackets

14 and 15 formed integral with, or rigidly secured to the respective side edges of the pressure plate 12 and lifting lever plate 13 at the bottom portion of the lever assembly.

A U-shaped spring member 16 is mounted on the top of the base plate 10 in the location shown in FIG. 2 and has its

free ends

17 and 18 turned inwardly at right angles and so arranged as to extend through apertures in the

side brackets

14 and 15 respectively. This spring member 16 is held in place on the base plate 1G by two pairs of opposed rear lugs 19 and 211, and by a pair of

right angle clamps

21 and 22 mounted at opposite sides respectively. As apparent from the figures, these

clamps

21 and 22 cause the free ends 17 and 1S of the spring member 16 to exert a constant pressure downwardly towards the base plate 10.

The side brackets 14 and 1S are formed with rearwardly extending cam-edged

portion

14 and 15. However the front bottom edge portions of these side brackets do not extend below the upwardly curving lower portion of the bottom face of the front pressure plate 12.

The holes in the

side brackets

14 and 15 through which the

ends

17 and 18 of the spring member extend are so positioned that the lever assembly 11, when not being operated, will be held by the

spring ends

14 and 15 in the normal position shown in FIGS. 1 and 3. In 4such position, the lever assembly will be held down on the portion of the flattened tube immediately beneath the lever assembly and thus in such position serve to hold the tube in place on the base plate 10. However manual movement of the lever assembly 11, causing the assembly to rock in either direction will cause the

ends

17 and 18 of the spring member 16 to be lifted and consequently such rocking of the lever assembly will take place only against the force exerted by the spring ends.

When it is desired to squeeze contents out from the tube T the operator exerts finger pressure on the top of the pressure plate portion 12. 1For convenience, the top end of this portion 12 is preferably formed with an enlarged rounded contact edge 23. Downward pressure on this contact edge 23, by rocking the lever assembly forwardly, causes the underside of the pressure plate 12 to engage the adjacent upwardly sloping surface of the tube and thus exert squeezing pressure on this area of the tube. Such downward pressure on the Contact edge 23 of the pressure plate 12 can conveniently be exerted, for example, by the thumb of the operator while the device is being held in one hand of the operator. When such thumb or linger pressure on the pressure plate 12 is released, the lever assembly 11 will immediately return to the normal position of FIGS. 1 and 3 under the force exerted by the

spring ends

17 and 18, thus holding the tube in place on the device without causing further dispensing of the contents from the tube.

When the lever assembly has returned to normal inoperative position, after part of the contents has been squeezed out from the tube in this manner, it will be necessary to shift the tube on the device with respect of the lever assembly. To accomplish this the operator then exerts finger pressure on the lifting lever plate 13, the top end of which preferably is narrowed into an upwardly obliquely extending tongue 13'. Finger pressure on the tongue 13 causes the lever assembly to be rocked rear-- wardly on the cam-edged portions 14', 1S of the

side brackets

14, 15, as illustrated in FIG. 5, which results in lifting the bottom, tube-engaging portion of the lever assembly from contact with the underlying tube. This enables the tube to be slid rearwardly on the device in preparation for the removal of more contents from the tube. Similarly when the tube is to be removed entirely from the device, or when the rear end of a new tube is to be set in place on the device, the pressuring down of the tongue 13', by raising the tube-engaging portion of the lever assembly, enables the llattened portion of the tube to be moved beneath the lever assembly. The

side brackets

14, 15 are spaced apart a distance greater than the width of the llattened tube and consequently the cam edges 14. 1S engages the top of the base plate It) but do not contact the collapsible tube.

It will be noted that at most only a restricted amount of the contents can be squeezed out from .the tube by pressing down on the pressure plate 12, and after the pressing down of the presure plate 12 has resulted in the dispensing of some of the contents from the tube, the device cannot be operated to cause more of the contents to be squeezed from the tube until the position of the tube is shifted on the device with respect to the rockable lever assembly. Thus repeated pressing down -on the lever .plate 12, such as might take place by a child playing with the device, will not result in any excessive amount of the material being discharged from the tube since, after the restricted amount has been discharged, it is necessary then to adjust the lposition of the tube on the device in the manner described.

As previously indicated the device can be conveniently operate-d entirely in one hand by the operator. Unlike some of the other tube holders an-d dispensers, it does not `have to be mounted on a wall or secured to any special fixture. Preferably the base plate 10 is formed with a pair of side hars 24 and l25 on the underside of the base plate on opposite edges respectively. These base bars enable the extreme end section of the flattened used portion of the tube to be Lfolded around under the base plate in the event the flattened use portion extends back beyond the end of the base plate. For this reason the base plate need be only of moderate leng-th and the unsightly appearance of a long flattened used end portion of the tube is avoided. As apparent, the device with the collapsible tube held thereon can `be set down on any flat sur-face when not in use. ln view of the simplicity of the construct-ion, the device can he produced at very moderate cost.
