Y. i Itis an object of the present invention to provide an improved container of the type described which shall be strong and durable inuse, capable of holding liquids Withoutleakage and inexpensive and simple tomanufacture. v
A further object of the invention is to. provide an improved joint for securing the fabric of the side Wall tothe metal bottom member.`
A still further object of the invention is to provideanimproved bottom, member for such containers, the bottom member being `formed of metal, plastic composition'or. other suitable substantially rigid material. 2
A still further objectof the inventionisj the 'of being permanently secured in position without periorating` or weakening the fabric.
These objects as well` as others which `will become apparent from the following detailed description of the-invention are attained by means of the present invention, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted towithout departing from the spirit or` sacricing the advantages of the invention.

Fig. 6 is a diagrammatic view showing a preferred methodl of geometricallylocating and designing the enlarged` space for the fabric hem between the bottom cups.
Referring to the drawing wherein like numerals refer to similar parts throughout the `several views, Il` is the body portion of the container` which is formed of waterproof fabric or the like eXible material. i As shown the body is tubular and is provision of a container of the-*character described composed of` a fewy number of parts` capable of' assembly and dis-assembly,` by simply sliding one partover` another orwhenassembled formed by overlapping and cementing or sewing two opposite ends of a rectangular piece of fabric together seam--like` as at 2f. While, as illustrated, the body is substantially cylindrical, it may be made in the form of a truncated cone or have other shapes. A small stitched hem 3 (Fig. 3) is providedat the bottom end of the tube to form a thickened or enlarged portion at this point. If desired'` a `reinforcing member such as a wire. or fabric cord (not shown) may be enclosed in the hem. l i
The bottom of the container is formed of` two saucer or cupshaped members 4` and 5 respec-` tively whichvareof the formV of a disc curving offperipherally on 'a radius` to terminate in a short` cylinder 6-6 at right angles to the base4 Asi stated, these members areformed oi` metal or plastic material or the like and are adapted to fit one Awithin the other withrtheir bottom Walls in surface to surfacecontact ahd'with the` lower endY of the fabric body portion sandwiched be tween the sidewalls of the members. For` this purpose inner member 4- is constructed with a cylindrical outside diameter equal to but not substantially greater than the inside diameter of the lower end of the fabric body portion, while the inside diameter of the outer member 5 is equal to but not substantially smaller than the outside diameter of the fabric body portion. Thus the cylindrical side walls of the cups, when the cups are nested or assembled with their side walls concentrically arranged, are spaced apart a distance equal to but preferably slightly less than the thickness of the fabric of the body portion above the hem. More or less frictional engagement or compression of the fabric between the side walls may be desirable depending upon the nature and texture of the fabric. 'Io increase compression, the cups are constructed with diameters more nearly equal so as to provide a normal spacing of the side walls substantially less than the thickness of the fabric above the hem. Greater compression is desired when the fabric is composed of soft loose-woven material than when the material of the fabric is hard-spun and tightly woven. If desired, a waterproof cement may be applied to the fabric before the outer cup is slipped over the fabric on the inner cup. This will not only form a good seal and serve as an adhesive but will lubricate the surface and reduce the friction encountered in sliding the outer cup in place.
In order to accommodate the bead or hemmed lower end of the body portion, an enlarged space 'I is provided between the two cups at the points of curvature of the flat bottoms of the cups into the short upstanding cylindrical portions. This space may take substantially any form, such as an annular channel or indentation in the wall of one or both of the cups, and may be located between the side walls of the cups below their top edge or between the bottoms of the cups. A preferred construction consists in curving the bottom wall of the inner cup on a longer radius than the curvature of the wall of the outer cup as illustrated in Figs. 3 and 6 of the drawing. The maximum width of space I is advantageously not substantially greater than the thickness of the hem 3 or two and one-half times the thickness of the fabric.
As shown in Fig. 6, the rounded annular bot tom portions of the cups intermediate the flat,
disc-like bottoms and the short cylindrical side walls, are, in lcross-section, curves of quadrants of large and small circles, respectively. The radius of curvature of therounded, annular bottom portion or corner of the inner cup is somewhat dependent upon the characteristics of the fabric of the side wall of the container. Generally, if the fabric used is thin and fiimsy, the corner can be made fairly sharp or in other words, the radius of curvature of the corner can be small. On the other hand, if the fabric is thick and stiff, a curvature of a larger radius is desirable.
One preferred method of obtaining the radius of curvature of the annular corner of the outer cup is illustrated in Fig. 6, wherein the arc B-K represents the curvature of the corner or bottom edge of the inner cup. As shown, curve B-K is the arc of quadrant B-O-K- To determine the center and radius of curvature of the bottom edge of the outer cup, radius line O-B is extended from B to C, as shown, a distance equal to the thickness of the fabric selected for the body of the container, and the distance B-C is laid ofi on O-B as shown at O-G. Using line G-C as one side, a square G-C-M-L is next drawn.
tact.
The diagonal, G-M, of the square so formed is the center line of the arc of the bottom corner of the outer cup. From point Q, where the center line crosses arc BK, the distance Q-R, equal, advantageously to about two and one-half times the thickness of the fabric, is laid oi on the line and at R a line is drawn at right angles to G-M which intersects lines L--M and C-M at F and H, respectively. Angles L-F-Rand C-H-R are then bisected as shown and. the point P on line G-M determined where these bisectors intersect. With point P then, as the center, and with the radius P-R, the arc D-R--E of the outer cup may be drawn.
Such construction is advantageous in that the approach of curves K-B and D-E toward each other at the top provides for extreme wedging of the hem on the lower end of the body portion and development of considerable friction and tightness between the cups when the fabric is pulled.
'Ihe body portion at the top is folded about a wire reinforcing ring 8 and stitched to itself as at 9. A fabric strap or handle I0 stitched to the top at each side as at I I is provided for carrying the container.
In the modified handle construction shown in Fig. 5, wire ringr S is formed with two upstanding diametrically opposite loops I2 which project above the top of the container for the purpose of attachment of a handle. f
To permit ready assembly of the bottom cups to the fabric of the body portion and to decrease wear on the fabric at this point, the top edges of the cups are advantageously rounded oif as shown at I3 and I4.
In one method of assembly of the container the inner cup is inverted and placed over a suitable mandrel. The tubular fabric body portion, also inverted, is next slipped down over the outside of the inner cup until the hem is positioned opposite the curvature on the bottom of the inner cup. The outer cup is then gently slipped or forced down over the fabric on the inner cup until the bottoms of the two cups lie in mutual con- A small pinhole opening I5 is provided in the bottom wall of the outer cup to permit the air between the cups to escape during assembly. A slight downward pull or jerk on the fabric body portion wedges the hem 3 tightly between" the walls of the cup after which pinhole I5 may be plugged by soldering to plug the hole or by spot welding the cups together over the hole. Additional spot welds may be provided, if desired, as at I6, I'I and I8. With this construction the more the pull on the fabric, as when material is placed in the container, the tighter the wedge or the joint and there is little or no tendency for the outer cup to slip off because of the absence of an entrance for air between the cups, because of the friction between the cups and, where the cups are spot welded, because of the spot weld.
If it is desirable to be able to disassemble the container forvreplacing the fabric body portion, spot welding of the cups together is dispensed with and the hole I5 reopened so as to admit air between the cups.
In actual practice, hole I5 may ofttimes be dispensed with depending upon the friction developed between the fabric and the cups and the character of the fabric used.
What I claim is: y

A container comprising a flexible, tubular fabric body portion provided with a hem at one end and a pair of intertting substantially rigid cup-shaped bottom closure memberseach provided with a substantially "cylindrical, vertically disposed side wall and a flat bottom Wall, said side walls being adapted to engage and hold the heinmed end of said body portion wedged between them said cup-shaped members forming the bottom of the container, the outside diameter of the inner cup at the top being substantially equal to the inside diameter of the fabric body portion above the hem, the inside diameter ofthe outer cup `at the top being substantially equal to the outside diameter of the fabric body portion above the hem, the side walls of said cup below their top edge defining an enlarged space for reception and retention of the hem.
