5 claims. (cl. 229-44) i This invention relates to a container.

An object of the invention is toprovide an inexpensive container for foodstuffs, and beverages which will not impart a foreign taste to its 5 contents.

Another object of this invention-is to provide a container suitable for holding oils and greasy substances. f

Known containers are usually made from paper 10 or cardboard, waxed or treated in various ways.

for the purpose of waterproofing the container and in some cases, wax is also used to act as a stiffening and supporting agent for thin materials.

'15 Such containers invariably impart a cardboard taste to their contents, regardless of temperature, and the taste is particularly noticeable when the containers are used for hot beverages.

It has been found that when ordinary con- 20 ltainers are used for a salad, such. as chicken salad or any food substance containing an oil or grease, the container quickly becomes saturated with oil which dissolves the protective coat ing, and the contents thereafter have a distinctive container taste.

It has been proposed to use the cellulose product now widely known as Cellophane for the purpose of lining containers, but thus far the results from eiorts in this direction have been unsatisv30 factory owing to the difficulty of manipulating thin sheets of Cellophane, and when seams or splices are made in this material, they lack the strength and insoluble qualities of Cellophane.

Furthermore a container lining of thin Cello--4 35 phane made according tothe usual practice, will not retain its shape and size as will waxed paper linings. Accordingly, the present invention hasfor an object the' provision of low-priced container 40 having a seamless lining of Cellophane Aor other thin material, suitably supported so that the liningwill retain its shape. v

It will be understood that when Cellophane is referred to hereinafter, that Cellophane or yany 45 'other material suitable for lining purposes, will be meant.

Other objects'will appear in the following description given with the aid of the accompanying drawings of which;

Figure 8 shows one form of a supporting member.

Figure 9 shows the supporting member of Fig- 10 ure 8 with the arms partly curved.

YFigure 10 is a plan view showing Figure 9 with the arms bent upward. Figure 11' shows a square of lining material.

Figure 12 is a plan view showing the lining ma- 15 terial shaped to t inside the .supporting member shown in Figure 10.

Figure 13 is a front elevation showing the partially folded lining of Figure 12 disposed withinthe arms of the supporting member shown The invention will now be described with the aid of the drawings:

Figure 8 shows a plan view of a supporting member blank provided with four arms, I, 2, 3,

and 4 integral with a circular central section 5 which forms a base for the supporting member.

In the case of a container having vertical sides such as shown in Figure 2, the arms may be shaped with opposite edges parallel and substantially at right-angles to those of the adjacent arms, the width of the arms being such that when formed. to the curved shapeshown in Figures 9 and 10, a small space is left between adjacent upright members formed by the 'respective arms 35 of the supporting member.

The Cellophane square shown in Figure 1K1 may be ,superimposed on the blank shown n Figure 8 so that the round base section .5 coincides with the circle located lin the center of 40 Figure 11 and arms I 'tol coinciding with the i arms of the cross indicated by dotted lines in the figure.

It will be observed that the Cellophane will extend some distance beyond the ends of arms L to 4.

The Cellophane may be fastened at various places to the supporting member by applications of suitable cement, but this-is not a necessary operation. l

The assembly may then be shaped about a suitable mandrel, and during th operation, the Cellophane is folded along dotte lines 6, 1, 8 and 9, and the folds are brought out between the arms of the supporting member producing a-serles ,of M

Aclockwise direction,

uniformly triangular shaped fins projecting outward from the sides of a hollow cylinder.

Thereafter any uneven edges ofthe Cellophane above the cylinder may be trimmed so that the Cellophane at this stage appears as shown in AFigure 13.

Figure 12 is a plan View showing the shape of the Cellophane liner on-the completion of this operation.

The 'Cellophane ns then may be tightly fountains, is desired, the Cellophane at this stage may be turnedover on the outside ofthe supporting member and the Cellophane rolled, cemented, or otherwise secured in any suitable manner on the outside of the container.

If, however, a stronger and more durable container is required, the Cellophane lining and supporting member may be inserted in a cardboard tube I0, which may be of inexpensive inaterial, since it does not come in contact with the contents of the container. The tube may be closed Vat one end-by a disc II, suitably secured to the tube by being crimped at the edges' as indicated by the reference character I2, or

by other desired means, or any other suitable outside shell may be used. The height of the outside tube is preferably less than that of the lining, but greater than that of the liningsupporting member, permitting the outer shell to be folded inwardly over the top of the supporting member, and then back over itself with the folds of the lining brought over the top and some distance down the outside of the shell and the Whole being tightly pressed or crimped thus sealing the tucks of the lining and eilectively preventing seepage of any sort. The edges of the layers of the lining material, varying in number, according to the tucks made therein,

u preferably terminate at an inverted bead or groove pressed in the side of the shell so that they coincide with a metal strip attached to a yCellophane-lined cover I4.

One form of a suitable metal sealing strip is shown in Figure l, indicated by the reference character I5. One end of the strip is provided with a tab I6 which`when inserted in the slot I1 at `the opposite end of the strip, may be pulled tight and then locked by bending inwardly toward the container, thus pressing the beaded part I8 and the Cellophane lining I9 of. the cover together with the various layers of the container lining into groove I3 sealing the containereifectively and making it air tight and splash proof.

While but one modication of the invention is described herein in detail, it will be understood that many modications may be made Without departing from the spirit thereof. For example. a cylindrical container has been described with a liner-supporting member having four arms.

vObviously a smaller or greater number of arms could be used. Three armsl could be used if a triangular-shaped container were to be constructed.

The arrangement shown, obviously could be an arm;

made into a container of square or oblong crosssection by suitably shaping the supporting member and not curving the sides.

l Likewise, containers having the shape of a truncated cone or pyramid might be made readily by suitably shaping the supporting member. For example, if the arms tapered outwardly from the base, a container with a flaring top could be made, and conversely, if the arms were smaller at the top, a container of truncated cone shape could be made, such as are commonly used for milk. y

It Will be noted that in all modifications of the present invention that the lining is seamless and in no case can the contents of the container come in contact with any cement or adhesive.

What is claimed is: l. In a container, a seamless Cellophane lin- Ling, supporting and retaining means for said lining comprising a base portion and a plurality of arms extending upward therefrom, a plurality of tucks corresponding to the number of said arms formed in said Cellophane, the respective tucks extending outwardly through the spaces between the arms, each tuck being folded over 2. In a container, a seamless Cellophane lining shaped to conform substantially to the shape of the inside of a container by means of a series of tucks formed on the outside of the lining, and means separate from the container about which said tucks may be folded to support said lining in the container.

3. In a container, a seamless Cellophane lining shaped to conform substantially to the shape of the inside of a container but being of greater height than the container, ,supporting means ailxed to said lining effective from the base to the top of the container, and means for sealing the top of the container, comprising a uniform fold of lining and container material at the top of the container, and cover means for retaining said fold in position.

4. In a container, a seamless Cellophane lining shaped to conform substantially to the shape of the inside of a container, supporting means effective from the base to the top of the lining, said lining and supporting means being within the container, an annular fold of said lining material depending from the top at the exterior of the container, a cover therefor having a Cellophane lining overlapping said annular fold, and means at the edge of said cover for holding the lining thereof tightly in contact with the lining of Athe container.

5. In a container, a seamless Cellophane lining shaped to conform to the general shape of the inside of a container by means of a `series of pleats formed in said lining, a supporting meinber disposed outside of said lining having a plurality of' openings through which said pleats extend, folds in the respective pleats on the outside of said supporting member, a shell for retaining said supporting member, an annular ring integral with said lining sealed on the outside of said shell, a groove in said shell formed at the edge of said ring, a cover for said container having a Cellophane lining, and a metallic ring secured to the edge of the cover adapted to register with said groove whereby the linings of the container and that of the cover may be tightly secured to each other.
