This invention relates to a holder for compressible tubes for dispensing tooth paste or the like.

One object of the invention is to provide a device of the character described including a casing in which a collapsible tube of paste is adapted to be received in inverted position, and improved means for progressively applying pressure from the inverted bottom end of the tube to squeeze' the paste from the tube orifice presented at the bottom of the casing, the pressure-applying means being movable away from pressure-applying position to facilitate. ready passage of the tubes into and out of the casing.

Another object of the invention is to provide a device of the character described which may be manufactured at a minimum of costas compared with prior art devices.

These and other objects of the invention will be manifest from the following brief description and the accompanying drawings.

Of the accompanying drawings:

Figure 1 is a vertical transverse cross-section through a tooth paste tube holder, embodying the features of the invention.

Figure 2 is a cross-section, taken substantially on the line 22 of Figure 1.

Referring to the drawings, the numeral designates a box-like holder or casing having a back wall ll against which a collapsible tube of tooth.

paste l2 may be backed in inverted position as shown, the tube being supported by engagement of a nozzle end of the same with a bottom wall l3 of the casing. The wall I3 is provided with an orifice l4 through which the dispensing nozzle l5 of the tube projects. vertically extending elongated slots I5, [6, in laterally spacedside walls [1,11 of the casing, may be a shaft i8 011 which is rotatably mounted a roller l9, of rubber or othersuitable material to-be-engageable with" the tube. The slots are in parallelism withxthe back wall l I, and the radius of the roller approximates the distance from the vertical center of the slots to the inner'face of said back wall, less at least the thickness ofthe tube in a flattened or collapsed condition.

The roller !9 is narrower than the space between the two side walls I! to provide substantial spaces zll and Zlon the shaft l8, between ends of the roller and the adjacent side walls l1. Extended between each: shaft-ipor'tion lBu, I8a in said spaces and the bottom wall I3 may be flexible elements 22, 22, of wire, cord, chain, or the like, adapted to be wound on said shaft portions as the shaft is rotated in counter-clockwise direction as'viewed in Figure 1. The shaft is so rotated as Rotatably received through 6 Claims. (Cl. ZZZ- 401) by manual operation of" a knob fixed on one end of the same projecting outwardly of the casing l0. That is; the "flexible elements are ar-' ranged to be maintained in taut condition, as

:the knob '23 is turned 'insaid counter-clockwise direction, by opposing pressure of roller l9 against an expanded .or filled part of the tube l2,'and

continued rotation of the roller in this manner,-

that is with forced downward movement of shaft 1! l8, from a position adjacent the top of the casing will progressively flatten or collapse the tube from the invertedbottom end thereof toward the downwardly presented nozzle end thereof, to squeeze paste from the nozzle openi-ngas desired. Al-- though the roller l 9 works mosteffectively when-- rotatably mounted on shaft 1-8, it is self-evident that if rollerl9 were-fixedon said shaft any differential-between the speed at -which. element 22 j. is wound and the peripheral speedofthe roller i would be compcnsatedfor by slidingmovement of the roller on the tube, as distinguished from rolling movement of the roller, as force is applied through nuts 25, 25 which are suitably anchored to the bottomwall 13. Thus the screws 24 are vertically adjustable from the exterior of the eas- "ing, to set both elements 22.at uniform tension.

An opening isprovided in the top of the casing Ill for inserting therein filled tubes l2, or for removing collapsed or empty .tubes from the same,

angles to the verticalportions of the slots in direction forwardly ofthef. back wall ,I l, whereby by unwindingtheneleiiientsii the 'rollerl9 may be; moved forwardly a distance sufficient to permit 1 passag of a full tube between .the' roller and said backwall. A cap 2'| is hingedionth'eouter face of bottom wall. I 3, in position to .be engageable with the projecting endof nozzle l5,'to close the opening of the same when paste is not being dispensed.

In use of the-holder l'ltdescribed above a s atooth paste dispensenit is adapted tobe mounted a b tween Well iaihsr e- Show? I in the drawing, as by means of screws received through spaced keyhole slots I l a in the back wall II. A tube of tooth paste I2 is maintained ment of the roller l9 therewith (see Figure 2), and

3 when it is desired to dispense 'a 'small quantity of paste from the nozzle I5 onto'a toothbrush, it is only necessary to turn knob 23 a fraction of a revolution in clockwise direction as shown in Figure 1, to wind the elements 22 on the shaft portions I 8a, and thereby to urge the roller I9 downwardly against the full part of the tube. When all of the paste been idispensed in this manner, the roller 1 9 may be moved upwardly and out wardly along the slot extensions (see chain-dotted lines in Figure 1) Him by rotating the knob 23 to unwind the flexible elements 22, thereby to permit replacement of the flattened tube 12 with a full one, through the top of the hole.
