' OLKUDE B DAVIS, 01 RICHMOND, VIRGINIA, ASSIGNOR OF ONE-HALF TO STEPHEN .A.
ELLISON, OF RICHMOND, VIRGINIA.
Be it known that I, CLAUDE B. DAYIS, a citizen of the United States, residlng at Richmond, in the county of Henrico,
State. of Virginia, have invented certain new. and useful Improvements in Collapsible Containers; and I 'do, hereby declare the following to be a full," clear, and exact description of the invention, such as will enable others skilled in the art to' which it appertainsto make and use the same.
This invention relates to collapsible tubular containers such as are used for holding paints, paste and'similar semi-fiuctuantmaterials, the object of the invention being to provide improved means that will insure progressively from its bottom or The invention consists in the prov'sion within the collapsible.- container, of a cylindrical follower, one end of which is flat and at right angles to. theaxis of the cylinder while the opposite end portion is beveled at' opposite sides to an edge that intersects the axis of the cylinder so that when the beveled faces are pressed through the wall of the container by the thumb and forefinger of the operator, the follower .will .be held against rotation and will move positively longitudinally of the container, to expel a corresponding portion of its contents.
I am aware .that a collapsible container has been provided with a follower in theform of a ball, but I have found in practice that when this is squeezed to urge it through the container, it is impossible to concentrate all of the pressure to result in a tendency of the ball to move-along the axis of the tube. On the contrary, and as the pressure on the ball will not necessarily be at two opposite points in a common plane with the .axis of the tube, the ball will have a lateral inclination which will serve to en large the tube and preclude efficient.v ejectment ofits contents. Furthermore, by form'- ing "the end of the cylindrical follower flat, an edge is provided that efiiciently scrapes the contained material from the wall of the tube.
In the drawing forming a portion of this Specification of Letters Patent.

specification and in which like numerals of eral views Figure 1 is an elevation showing a container embodying the present invention, a part of the contents of the container having been ejected. v
Fig. 2 is a central longitudinal section on the line 22 of Fig. 1.
Fig. 3 is a detail perspective view of the follower employed by me.
- Referring now to the drawings, there is shown a collapsible foil tubelO having at one end the usual threaded nozzle 11 with reference indicate similar parts in the sevwhich is engaged the removable cap 12, the
opposite or bottom end of the tube being 'fol'ded upon itself in the usual manner as illustrated.
Within the tubelO at the'bottom thereof is disposed a follower 13 of cylindrical form having its bottom end beveled at oppositefaces as shown at 14: and 15. The follower may be made of wood or of other suitable material and while fitting the tubular bottom 10 with a sufficient closeness to insure ejection of the contents of the tube through the nozzle when the follower is moved in the direction of the latter, is slidable to accomplish the ejection of the contents, by pressure with the fingers of the operator against the beveled-faces 14 and 15 through the collapsible foil wall of the tube. a
In practice, when the contents of the tube is to be ejected, the cap is removed in the usual manner and pressure of the thumb and forefinger is brought to bear against the faces 14 and 15 through the wall ofthe tube, with the result that the wall is collapsed and the follower is slid in the direction of the nozzle andthe contents is forced through thelatter.
After each operation, the collapsed lower I its end nearest the outlet opening of the container flat and its opposite end portion beveled on opposite faces whereby movement of the follower axially of the-container un der the influence of pressure upon its beveled faces through the wall of the container,
is insured.
In testimony whereof, I afllx my signature, 1n the presence of two w'ltnesses.
