This invention is embodied in a holder an end section 13, closing one end of the body adapted to contain and support in a predesection and detachably secured thereto by termined position, a collapsible tube charged means such as hooks 14, pivoted at 15 to the with plastic or semi-tluid material, such as body section, and studs 16, fixed to the end tooth paste or shaving cream, the holder havsection.

When the valve is closed, extruding movement of the presser is prevented.

In Figures 1 and 2 the roller 30 is shown as hearing on the usual. folded and closed end 180 of the tube, said end being inserted between the roller and the bed by an endwise movement of the tube. Said movement causes the inclined face 31 of the presser to form a flattened incline on the inner end of the tube, said incline progressing toward the outlet when the springs are permitted, by the opening of the valve, to move the presser.

Figure 7 shows the holder proportioned to permit the insertion of the tube in an inclined position, as shown by full lines, and then be moved downward to bear on the bed 17 as shown by dotted lines.

The presser body may be provided with nature.

studs 33, projecting through longitudinal slots 34 in the body section 12. Said studs permit the operator to conveniently force the presser to the retracted position shown by igures l and 7.

To operatively assemble the holder and tube, the end section 13 is removed, the presser is retracted,the end portion 18a of the tube is inserted between the roller 30 and the bed, and the end section 13 is secured in place, the valve being closed. The presser is then released and forced forward by the springs until the tube mouth 21 enters the outlet portion 20.

When a portion of the charge is to be extruded, the operator opens the valve 22, holds it open until a sufficient quantity is dispensed and then closes the valve. The force of the springs is sufiicient to cause the presser to flatten nearly the entire length of the tube.

When the tube is exhausted, the end section and the tube are removed and a charged tube is inserted.

The tube 18 here shown is supposed to be of the usual soft metal variety. The tube may be made of rubber, if desired, and adapted to be refilled and repeatedly used.

I claim:

1. A holder having a bed adapted to support a collapsible tube charged with plastic material, a dispensing outlet adapted to be coupled to the tube mouth, a valve adapted to open and close said outlet, a presser movable in the holder and formed to cooperate with said bed in collapsing a tube supported thereby, means for guiding the presser, and resilient means normally urging the presser toward the outlet, said presser being formed to progressively exert collapsing pressure on the tube, and thereby extrude the charge therefrom when the valve is opened, the closing of the valve preventing extruding movement of the presser.

52. A holder as specified by claim 1, composed of a body section having said bed and
