11 Claims. (C1. 222-102) tents from a collapsible tube.

A further object of the invention is to provide a device for supporting and dispensing the contents of collapsible tubes of different diameters and/or lengths.

The invention has for a still further object the provision of a combined adjustable, supporting and dispensing device forcollapsible tubes that is simple, compact and sturdy in construction, that is reasonable in initial and maintenance costs, that may be readily assembled, adjusted and dismantled, and that iseflicient and troublefree in operation.

The foregoing objects, as well as other objects, together with the advantages, construction and operation of the dispensing device of this invention will be readily comprehended by persons skilled in the art from the following detailed description and accompanying drawing, which respectively describe and illustrate a preferred arrangement of elements `embodying the invention.

In the drawing:

Figure 1 is a view in side elevation of a device constructed in accordance with the invention and having a partially depleted collapsible tube mounted thereon;

Figure 2 is a top plan View of Figure 1;

Figure 3 is a central longitudinal cross-sectional view taken along line 3 3 of Figure 2, with the screw cap of the collapsible tube omitted;

Figure 4 is an end elevational view of the device of this invention as observed from the right of Figure l, the collapsible tube being omitted; and

Figure 5 is a view taken along line 5-5 of Figure 2.

Referring now to the drawing wherein like reference numerals denote corresponding parts throughout the Vseveral views, the device of this invention include a base Iii, the bottom surface of which (not shown) is preferably knurl-lin'- ished so as to minimize 'the possibility of slippage when the device is held in the palm of a hand. The base is provided with a pair of longitudinal parallel grooves I2. One such groove, as best shown in Figures 1 and 5, is formed in each side of the base. Secured to the rear end of the base, preferably by welding, is an upstanding bracket I4 having a through vertical drill hole I6 in a forward extension I8 (Figure 3). A member 2U made of suitable spring steel is secured to the top of bracket I4 by screws 22.

Integral with member is a stationary upper jaw 24 that overhangs bracket extension I8 and that constitutes an element of a clamping mechanism or vise which will now be described. The clamping mechanism also includes a plunger 26 reciprocable in drill hole I6 and normally urged upwardly by a helical compression spring 28 that is located within the drill hole and bears against the upper surface of the base and the under sur- 2() face of the plunger. A lower jaw 30 has an opening 32 (Figure 2) which receives the upper end of reduced diameter of plunger 26 whereby the lower jaw is press-fitted to the plunger. The lower jaw is provided with extensions or wings 33 (Figure 2) that project laterally beyond upper jaw 24 to facilitate downward movement of the lower jaw and plunger against the action of compression spring 28. y

As is best shown in Figures 1 and 3, upper jaw 24 is generally concave upwardly, while lower jaw 3D is generally concave downwardly. Further, both jaws are of suiiicient width to accommodate and clamp therebetween the clipped or vfolded closed end 34 of a collapsible tube 36.

The illustrated tube is partiallydepleted of its contents and includes the usual threaded disch-arge neck 38 (Figure 3). The tube neck is adapted to project through and beyond a central opening 40 in a dished support member42. A conventional tube cap 44 threadedly engages the tube neck to protect the contents of the tube against evaporation or contamination bythe air when the contents are not being discharged-from the tube. Support 42 has an integral depending plate 46 formed with a rearwardly projecting flange 48 (Figure 3), that bears against the upper surface of base IIJ,y and a pair of parallel spacedapart inwardly projecting tongues 50 that register With grooves I2 in the base to permit sliding movement of the support along the base. Support 42 is illustrated as being at the forward end of the base. It will be apparent that the support may be moved along the base to any desired location and locked in such location by a knurled Set screw 52v (Figures 2 and 4).

kmounted in support 42. `positioned intermediate the clamping mecha- A roller carrier, generally denoted by numeral 54, is movable klongitudinally of the tube in the direction of its discharge end to compress the tube and elect emission of the contents of the tube through neck 38. The carrier comprises a lower roller support frame 56 having a pair of parallel side walls 58 and a bottom wall 66, which is notched as indicated at 62 (Figure 2) for the reception of extension I8 of bracket I4 upon predetermined movement of the carrier toward the left as viewed in Figures 1-3. Depending from bottom wall 60 is a pair of spaced-apart, parallel, inwardly projecting tongues 64, each of which registers with a corresponding groove I2 in the base. A lower cylindrical roller 66 is provided with coaxial press-fitted trunnions 68 that are rotatably supported by side walls 58.

The carrier also includes an upper roller support frame or bracket 1U having a top wall 72, terminating in a forwardly and upwardly projecting lip 14, and depending side Walls 16. Bracket 'I0 is pivotal with respect to lower roller support frame 56 through the medium of coaxial pins 18. An upper roller 8U having press-fitted trunnions 82 is positioned between side walls 16 and freely rotatable with respect to the bracket. It will be noted from an examination of the drawing that upper roller 80 is positioned above lower roller 66 and is rotatable about an axis parallel to the axis of rotation of the lower roller. A fiat stock spring 84 is press-fitted in an opening provided in wall 12 and bears against the rear of support frame 56 in a manner t0 normally urge bracket in a counter-clockwise direction, as viewed in Figure 1, to thereby move upper roller 8D away from lower roller 66.

For the purpose of outlining the operation of the illustrated embodiment of the invention, it is rst assumed that the parts are in the relative position shown in the drawing and that the ldevice is being held in the palm of the left hand of a user. At such times, the clipped or folded end 34 of collapsible tube 36 is clamped between

jaws

24 and 30 of the clamping mechanism, while the discharge end of the tube is Roller carrier 54 is nism and forward support 42, the rearward por- 66 and 80 positioned respectively below and above the flattened portion of the tube.

When it is desired to withdraw a supply of paste material from the tube, the operator removes tube cap 44 and then grasps lip 'I4 of bracket 'l0 with the lingers of his right hand. He next exerts a combined downward and forward thrust on bracket 10 against the action oi spring 84, causing upper roller 80 to move downwardly toward lower roller 66 and simultaneously moving roller carrier 54 forwardly or to the right as viewed in Figure i. This lattens an additional portion of the tube and effects emission of a quantity of the contents of the tube through thread discharge neck 38.

It will be apparent that the device of this invention is adapted to readily and effectively ect substantially all of the contents from tube After the tube has become depleted, it may be readily and quickly removed and replaced with a full tube. The depleted tube may be removed from the device by nrst detaching its discharge end from support 42, and next pressing downwardly on extensions 33 of lower jaw 30 to disengage the closed end of the tube from the clamping mechanism. The tube may be then withdrawn from between rollers 66 and 8U, Roller carrier 54 is moved rearwardly or toward the left as viewed in Figure 1 until extension i8 of bracket I4 registers with opening 62 in the support frame bottom wall 60. Side walls 58 are spaced apart a sufficient distance to permit entry of the clamping jaws therebetween when the roller carrier is moved to its rearwardmost position. A full tube may then be mounted in the device and the foregoing procedural steps repeated.

From the foregoing, it is believed that the construction, operation, and advantages of my present invention will be readily comprehended by persons skilled in the art. It is to be clearly understood, however, that various changes in the apparatus Set forth above may be made Without departing from the scope of the invention, it being intended that all matter contained in the description or shown in the drawing shall be interpreted as illustrative only and not in a limiting sense.
