Claims.

This invention relates to a container.

An object ofthe invention is to provide an inexpensive container for foodstuils, and beverages which will not impart a foreign taste to its contents.

Another object oi this invention is to provide a container` suitable for holding oils and greasy substances.

Still another object is the provision of a low priced container suitable for soda fountain use.

A further object is the provision of alcontainer which may be readily converted into a dinner plate.

Known containers are usually made from paper or card-board, 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 stiiening and supporting agent. for thin materials.

board taste to their contents, regardless of temperature, and the taste is particularlynoticeablewhen the containers are used for hot beverages.

It has been found that when ordinary containers 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 the contents thereafter have tainer 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 efforts in this direction have been unsatisfactory 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 celloa distinctive conyphane. Furthermore a container lining of thin cellophane made according to the usual practice, will not retain its shape and size as will waxed paper linings.

Accordingly, the present invention has for an object the provision ci a low-priced container having a seamless lining of cellophane or other thin material, suitably supported so that the lin-- ing will retain its shape.

It will be understood that when cellophane is referred to hereinafter, that cellophane or any other'materiai suitable for lining purposes will be meant.

Other objects will appear in the following de scription given with the aid ofthe accompanying drawings of which duced scale.

container formed without cutting, from a pattern such as shown in Figure 9.'

Figure 8 is a horizontal section taken through 8-8 of Figure 7.

Figure 9 is a plan view-on a reduced scale of the sides of the container shown in Figure 'l as it appears before'folding.

The invention will nowv be described with the aid of the accompanying drawings.

Figure 3 shows an octagonal-shaped piece of 4 cardboard or other suitable material I having a protective coating, and

circular base section at the center, indicated by dotted line 2, from which a series of regular wings or blades 8 to I0 is formed -by cuts which radiate from line 2 to the corners of the Octagon.

In constructing this modification of the invention, a sheet o! cellophane or other lining material, octagonai in shape but larger than the cardboard, indicated in Figures land 2 by reference character Il, is placed over the cardboard, so that the latter is centered in respect tothe lining material. It is preferred that the lining` material be cemented to corresponding parts of the respective blades or wings Ito I0 formed by the cuts in the cardboard at some place off-center,

thus leaving the cellophane unattached /to the opposite half of the wing. This cementing is largely used to aid in retaining the parts in position during a subsequent folding operation as the structurels such when completed that no cement is required to make the respective parts keep their-shape.

. The cardboard and cellophane are then folded about a suitable mandrel, with the successive wings 3 to i0 overlapping each other, forming regular lfolds I2 of cellophane which are caught between the `by' the wings I Y Figure 5 is a horizontal section taken through overlapping edgesof the shell formed Since the-cellophane octagon was larger than the cardboard, edges of the lining will extend beyond the tops of the wings and this edge is folded over lthe outside of the vessel at I3, and

' with any cement preparation. Furthermore, the

shell material may be quite thin, and not necessarily Very strong, as one layer of the material reinforces the others.

Figures d, 5, and 6 show a modification in which the outer shell is formed by four wings I5 to I r8, which are divided by cuts extending outwardly from a central portion i9 which forms the base of the icintainer, to the edges of a square. lophane is superimposed on the ,cardboard square, the Cellophane square being the larger, and after being cemented together in desired places, the arms and the lining material, indicated generally in the drawings by reference character 20, arel folded upward and curved about a suitable form so that the respective Wings overlap each other retaining tucks 2i of Cellophane 2li between the wings. As in the case with Figure 1, the excess of lining material is folded over on the outside of the cup l forming an outside rim d of lining material cardboard 29 with the center or base portion indicated by the reference character 30, from which radiate a series of dotted lines 32 regularly spaced and extending to the corners of the piece, While a second series of regularly-spaced dotted lines extend to the perimeterrof the octa-l gon, in the present embodiment, they are shown as intersectingthe faces at a point ofi center. The dotted lines indicate the places where the cardboard 29 and a larger, similarly shaped,

piece of lining material 34 superimposed thereon and secured thereto by sui/table means, are to be folded. e

As in the previous cases piece 29, together with the lining material, are formed about .a suitable mandrel and tucks are made where indicated by the dotted lines, so that the completed article appears Ain section as shown in Figure 8. 'I'he excess Cellophane is shown in this embodiment as being rolled over the edge' An advantage of this invention, particularly in the embodiments shown in Figures l and 7,

In this embodiment a square of Celis-that they are especially adapted for food conrims might be broken or torn after the container is opened in order that the shell and lining material might be spread open to a greater or less extent, whereupon the container will be in effect, an octagonal food plate, the partially open folds made during thev original forming of the container serving to keep the parts in a concave condition. Awire loop, indicated by dotted. lines and reference character 36 shows an arrangement for breaking the rim.

What isclaimed is:

l. The method of making a container which comprises superimposing a layer of lining material over a piece of cardboard having a plurality of cuts radiating from a central` base section, and forming the sides of the container by bending the-sections of the cardboard formed by the cuts upward so that the respective sections overlap each other and support tucks formed in the lining material, and thereafter folding said lining material over .the edge of the cardboard in the form of an annular ring.

2. The method of making a container which comprises dividing a regularly shaped geometric figure of container material by cuts extending from the edges thereof to a central section to -be l used for a. base, then superimposing lining material of greater area than said gure thereon, then forming the sides of the container by bending the sections formed by the cuts so that they overlap each other and retain tucks of lining material, and thereafter forming a rim on the outside of the container from said lining material.

3. The method of making a container which ycomprises dividing a regularly shaped geometric figure by cuts extending from the edges thereof to a central section to beused for a base, then superimposing lining material of greater area than said figure thereon, then forming the sides of the container by bending the sections formed by the cuts so that they overlap each other and retain tucks of lining material, and thereafter forming a breakable rim on the outside of the container from said lining material.

4. A container comprising an outer shell consisting of a plurality of flaring, overlapping Wings integral with a base section, a seamless l angular-shaped tucks retained by said-overlapping wings, and a ring on the outside of said shell at the top thereof formed integral -with said lining materiai, 'means associated with said ring for lbreaking the same whereby said container can be converted into a dinner dish.
