6 Claims.

This invention relates to paste dispensers, and more particularly to means for housing a flexible tube containing a plastic or semi-plastic material and for permitting the dispensing of said mate rial from said tube in regulated quantities.

One object of this invention is to provide a housing for a conventional paste tube which is manually operable to extnude the paste through the neck of the uncapped tube.

Another object is to provide a paste dispenser of the above nature which will be simple in construction and operation, inexpensive to manufacture, light in weight, compact, easy to install and manipulate, and very eflicient and durable in use.

With these and other objects in view, there has been illustrated in the accompanying drawing (consisting of one sheet of flve figures, numbered Figs. 1 to 5, inclusive), one form in which the invention may conveniently be embodied in practice.

In the drawing:

Fig. 1 is a longitudinal cross-sectional View of the paste dispenser with a full tube of paste shown in operative position.

Fig. 2 is a longitudinal crosssectional view of the same, showing the appearance of the device after the paste tube has been collapsed.

Fig. '3 is a rear end view of the same.

Fig. 4 is a transverse cross-sectional view of the same taken along the line 44 of Fig. 2, looking in the direction of the arrows, and

Fig. 5 is a fragmentary side view of the cap end. ofthe device.

Referring now to the drawings in which like reference characters designate corresponding parts throughout the several figures, the numeral I indicates a cover, the numeral I I a base plate, and the numeral I2 a presser plate, all of which are hinged together at one end upon a common pintle I3, to form an elongated housing of suitable length, width and depth, to conveniently enclose a conventional flexible paste-containing tube M.

The front end wall l of the paste dispenser is provided with a centrally-disposed elongated transverse opening [6, adapted to loosely receive a dispensing neck I! of the flexible paste tube I4.

The central portion of the base plate ll throughout the length thereof is offset inwardly to provide a wedge-shaped back rest l8 for the flexible tube 14. The marginal edges of the base plate I I project outwardly to form lateral flanges |9l9 and an end flange 20.

The paste dispenser may be supported in any 2 suitable manner, as by means of wood screws 2|--2l passing through holes formed in the lateral flanges l9l9 and into a suitable support or mounting such as a bathroom wall.

The cover I0 is provided with a pair of slots 22-22 to afford free passage for a U-shaped operating handle 23 which is rigidly attached to the presser plate l2 in any suitable manner.

A short curved flap 24 is hinged at 25 to the presser plate l2 adjacent the operating handle 23 and has a free outer end 26 designed to engage the yieldable portion of the tube l4 behind the relatively rigid conical end 21 thereof, as the flexible wall of said tube collapses (see Fig. 2).

A closure cap 28 is hinged at 29 to the end wall l5, and is adapted when open to afford access to the dispensing neck I1 and when closed covers the elongated opening l6 and the dispensing neck l1.

Operation The dispenser will first be mounted upon a suitable support, as by means of the wood screws 2l 2|'. The cover l0 and the presser plate l2 will then be arranged in the open position substantially as shown by the dot and dash lines in Fig. 2. A conventional flexible paste-containing tube M will then be inserted in the cover I!) so that the dispensing neck I! of the flexible tube I4 is disposed in the elongated laterallyextending opening l6 of the end wall l5, and with the presser plate l2 located adjacent the cover It.

The cover is then snapped against the base plate ll whereupon the several parts will assume the position substantially as shown in Fig. 1. I

To dispense the paste, the closure cap 28 is opened about its hinge 29, and the operating handle 23 pressed inwardly until the presser plate 12 flexes the wall of the tube 14 sufliciently to dispense the desired portion of the contents of the tube in ribbon or round form.

As the tube empties, the wall of flexible tube M will flatten and the presser plate l2 gradually will approach the sloping back rest I8 to collapse the walls of the flexible tube M with a substantially uniform pinching action. As the walls of the flexible tube thus collapse, the dispensing neck I! will move laterally in the elongated opening l6, and the flexible tube M will mold itself to the inwardly-offset contour of the base plate ll until the movement of the head end 21' is arrested by the end flange 20 (Fig. 2);

In the region of the dispensing neck I I, the flexible wall of the paste containing tube I4 will be held open by the relatively rigid outwardly flaring conical skirt 2'! which merges with the dispensing neck IT. The flap 24 will pivot upon its hinge 25, thus increasing the amount of paste which can be dispensed and avoiding injury to the rigid conical end section of the tube.

The presser plate l2 will, however, continue to move towards the back rest l8, progressively flattening the paste containing tube M from its sealed flat end. 30 to the rigid conical section until the presser plate l2.v and base plate H come into abutment throughout their entire length, as shown in full lines in Fig. 2, at which time the tube I4 will be substantially empty.

The cover It] may now be opened and thecollapsed paste tube l4 removed and replaced by a new one. I

While there has been disclosedin this specification one form in which the invention. may. bev embodied, it is to be understood that this form isshown for the purposeofillustration only, and

that the inventionisrnot tobe limited to the specific disclosure; but way be modified and em bodied in various other, forms without departing from its spirit; Inshcrt, the invention includes all the modifications and embodiments coming within the scope of the-following claims.

Having thus, fully-described the invention, what is claimed as new, and, for which it is desired to.
