CONTAINER FOR PLASTIC MATERIAL.

Application filed April 22, 1924. swarm. 708,284.

This invention has for its object a container for plastic material, such as shaving and dental creams, pastes, Vaseline, ointments,

printers ink, paints, etc,, which is particularly simple and economical in construction and by which the head and cap or closure is dispensed with, and the tube produced, filled and sealed more economically than heretofore.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

. In describingthis invention, reference is had to the accompanying drawings in which like characters designate corresponding parts 16 in all the views.

Figures 1 and 2 are elevations of this container taken at a right angle to each other.

Figure 3 is an end view. Figure 4 is a View similar to Fig. 3, showing a-tube formed with an exit slit.

Figure 5 is a vertical sectionalview of one end of the container.

This container comprises generally a tubu-. lar compressible body having its ends flat- 2 tened. or pinched together or sealed, reinforcing means at such flattened ends, the reinforcing means at one or both ends being arranged to expose a portion of such sealed end, preferably the intermediate por 80 tion of such end, in drder that the exposed portion may be a slit, to form a discharge outlet, out of which the contents can be discharged and that the exposed portion may again squeeze or be squeezed together to temporarily seal the container until next used. The body '1 is composed of flexible compressible material, and the ends thereof are pinched together in a manner similar to the bottom end of tubes usually employed for holding tooth paste, shaving cream and the like. These ends are rolled or folded upon themselves, as shown at 2 in Figs. 2 and 5, and one end, as the bottom end, has a V or U-shaped reinforcing clip or cla'inp 2. One side of the clamp 2 is doubled in at 2 toward the bend of the U-shaped formation and interlocked with or'rolled in with the rolled end 2. The clip 2 may also have a perforated ear 2 struck therefrom, for the purpose of hanging the tube with the discharge end down. v

' The other, or discharge end, instead of having the usual head, nipple and cap, is also flattened and rolled and provided with reinforcing means through a portion of its extent only, so that a portion of the sealed or rolled edge isexposed. As here shown, such reinforcing means comprises a U or V-shaped clip 3, clamped upon the rolled or folded end of the tube, the intermediate part of the clip having a output 4 which leaves the inter-. mediate portion of such edge exposed, so that, 1t may be out or shaved off with a knife ,to form a discharge oriflce or slit 5. The reinforcing means or clip 3, is formed with one wall 4* doubled in, and interlocked with the rolled end of the tube at the discharge end of the tube.

In use, the tube is packed with its exposed edge uncut and the user first cuts or shaves off the edge to form the slit 5.

Upon squeezing the tube, the material will open the slit slightly and will pass out through the slit. After each use the tube closes itself due to the elastic quality of the metal or can be closed by merely pressing together the walls of the slit 5.

Owing to the fact that the edge is rolled, as at 2, there is but one thickness of metal at one side of the slit 5, as shown in Fig. 4, and this thickness yields outwardly, as shown in Fig. 4, when the tube is compressed to discharge the material therefrom, and closes when thepressure is relieved. The tube is thus formed with an expansible and contractile discharge orifice.

This tube is particularly advantageous in that it is not only more economical in manufacture, as it dispenses with the head, threaded nipple and cap,'but also is more satisfactory to use as there is no closure to become lost and the tube very readily closes after being used and, if not closed, no dama e is done to the I 'having a cut out to expose a portion of such sealed edge.

3. A container for plastic material comprising a tubular compressible body having its ends flattened and sealed together, reinforcing means at one end extending throughout the width of the sealed edge, and reinforcing means at the other end extending across such sealed edge and formed with a I cut out exposing a portion of the sealed edge.

4. A container for plastic material comprising a compressible tubular body flattened at its ends and having its flattened port-ion rolled, a V-shaped reinforcing strip clamped ID on one of the rolledends and extending entirely across the same, and a V-shaped reinforcing means clamped upon the other folded end and being shaped to expose a, portion of such folded end.

In testimony whereof, I have hereunto 15 signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 21st day of J an., 1924.
