'somma (Cilaos-4s) This invention relates to a new and. useful lcontainer, particularly one to be utilized in the pack- `aging of edibles, such as cookies, cakes, biscuits, nuts, fruit, candy, raisins and the like. These o products are ordinarily packed fresh from the ovenor process. In this condition they contain considerable moisture and,'in some instances, are hot and therefore occupy a considerably larger volume than when they are cold. lit' At one time it was the practice to pack such v commodities upon 'a sheet of strawboard or fiberboard.' However, this practice was not successfulv because moisture condensed upon the transparent wrappers, obscuring thefl products and making the package unsightly. In addition, when the products cooled and shrank, the wrapper-would be- "come loose because, while it had been initially drawn tight over the products, the products, upon shrinking, occupied less volume 'and did not stretch the wrapper. This made an-unsightly package, one givingl the appearance of an old packag'ewsince even a suggestion ofage and Y staleness-is highly undesirable in the trade, this manner of packing was not'successful.

In accordance with my invention I provide a package in which the condensation of moisture is obviated, and, at -the same time, the wrapper is kept stretched and taut so that an acceptable package is provided.l This package I am able 3 to provide by utilizing Ia backing of corrugated paper, the backing being provided in a. particular' 'manner to -accomplishthe en ds of the present invention. It is in general the broad object 'of thepresent invention to providev a novel package ior4 edible products.

The invention includes other objects and fea.- tures of advantage, some of which, togetherwith the foregoing, will appear hereinafter wherein I '40 have disclosed'certain preferred ways'in. which I practice my invention. Inthe drawings accompanying and forming .a parthereof 'I have disclosed certain packages to illustrate my present.

preferred practice. However, it is to be understood that the invention is not to beV limited to 4 these but is to be accorded a range of equivalents in accordance with the claims. l In the drawings, Figurel is a perspective view illustrating aj package embodying features of the 50. present invention.

rugated paper. This material, as appears in Figure 5, is made up'of abase strip II and a corrugated strip I2 secured to the base strip by a. suitable adhesive and formed in a manner well known in the art. 4This material is relatively light and inexpensive to manufacture and yet 20 Iprovides resiliency and strength.

In accordance with this invention, I take a sheet of corrugated paper I3 and, to provide the structures shown in Figures land 2, provide score lines Il and I5 therein. The corrugated strip is then bent in either direction uponthe scorelines 25 .I4 and I5, and sides. I6 and II are formed. The

products, in this case small cookies or cakes, indicated by numeral I8, are placed upon the base orsmoothside of the corrugated strip, the ends vIl and I'I being bent back upon the strip.` Under 30 tension, the transparent cover Il i's then placed over the strip and is secured' thereto, usually to the back, to provide a substantially airtight package. Subsequently, even if the products cool and vshrinkin Lize, it will be found that the transpar- 35 ent material I9 has been kept taut over the prod-- ucts. This is because the sides I8 and I'I tend to straighten out or unbend. As the products cool they move slightly, exerting a' constant=ten sion upon the .transparent material which has 40 As suitable transparent material I can use cellophane, glassine, or other transparent ina-A terial as is usually employed in the art.

The package disclosed also prevents the con- 45 densation of moisture upon the interior surface of the transparent material. 'Apparently this is due -to the air circulation permitted by the plurality or conduits provided by the corrugated material.

In that form of the invention shown iii-Figures 3 and 4, astrip 2| of corrugated paper il provided with score lines 22 and 2l parallel to each l other'and extending transversely to the corrugations. Score lines 24 and-2l are provided ad- 55 jacent the ends of the strip and extend parallel sections 21 are provided which, when turned into to the corrugations so that the strip can be suitably bent into the form of the box as appears in Figure 3.l I prefer that the score lines 22 and 23 beyond the score lines 24 and 26 be so deep as to actually sever the corrugated paper so that end position, engage end areas 28 to form a box structure. The ends 2l`and 28 can be secured together inserted with the corrugations uppermost,lso that' when 'the cookies are inserted they engage the corrugations and do not slide, although the strip can b'e placed inthe bag with the smooth side Pacldng of the cookies to against the products. an undue extent in the bottom of the bag is not encountered if they engage the corrugated face. The corrugated strip 32 inserted in the bag 3| is also bent slightly upon itself so that when the products are inserted the strip of corrugated material is in tension and exerts a stretching effect at all times upon thetransparent bag 3| to maintain the bag taut over the products. In'Figure 6, I have indicated this bending and its position by the letter M, the sheet being curved slightly in the bag about the crease line M-M. The Wrapper can be secured to the back'face of strip 32 if it is desired to economize on wrapping material.

In Figures 8, 9 and 10 I-have shown a carton embodying the features of the invention. In this form I manufacture a continuous strip of corrugated material, severing the strip at edges 36 and 31 and creasing it at 38,39 and 40 so that the severed strip can be bent into a tubular sleeve with edges 36 and 31 suitably secured together. One face of the sleeve is cut'with an H cut- 4|, the HA being deep but leaving uncut portions 42.

`In use, the sleeve, cut and joined, is readily handled and shipped ilat. When it is to be lle'd,` the sleeve is unfolded and H sections 43 depressed.

The corrugations of each H section engage the corrugations of the bottom section and lock the two together, the sections bending' easily along the proper corrugations. AThe box thus formed .is ilied with the commodity. Since the H sections provide rigid ends, the carton can be wrapped with a wrapper M on a standard Wrapping machine. the wrapper being sealed at the box ends.- This enables a saving in wrapping material tobe made.

The wrapper, Cellophane, or another regenerated cellulosemateriahor glassine, can be used as the wrapper, being stretched over the box.

It is believed to be apparent that the invention disclosed can be embodied in various other useful forms to provide advantageously employed containers for the productsindicated and those of a like nature.

What I claim as new and desireto secure by Letters Patent isz- 1. A package for products comprising a ilat sheet of corrugated paper for supporting prod'- ucts on the corrugated face thereof,.and 'a wrapper of transparent material stretched over said products and said sheet to retain products on said sheet, said sheet being foldedalong a line substantially at the middle of said sheet and extending transversely. to corrugations in-saidk paper whereby said sheet4 is bowed upon itself to stretch said Wrapper.

2. A -package forvproducts comprising a Atransparent baglike container, and a substantially ilat sheet of corrugated paper positioned in said container to provide a substantially fiat, side in said container with corrugations in said sheet, extending in one direction, said sheet being bent slightlyv V upon itself in a direction transverse to the direction of the corrugations to stretch said container over said products. 3. A package for products comprising a transparent baglike container, and a substantially flat sheet ofA corrugated paper'positioned in said container to provide a substantially at side .in saidcontainer with corrugations in said sheet extending in one direction and uppermost in said-container to provide a rough surface for engagement with products in said container, said'sheet being bent slightlyupon itself in a'direction transverse to the direction of the corrugations` to stretch said 'container over said products.

4. A package for products comprising a sheet of corrugated paper bent upon itself in a direction transverse to that of the corrugations to provide opposite terminal edge portions at an angle to each other and tensioned with respect to each.

other through the portion ofthe sheetiritermediate said terminal edge portions whereby said portions tend to return freely to that positionv which said`portions occupy when the sheet is fiat, and a transparent wrapper extended about said sheetand over products supported on a 'face of said sheet and resisting return of said tensioned Y edge portions whereby said wrapper is maintained taut over said products.

A package liner for use in a package wherein a plurality of products are-'carried in said packagevon one face of said liner with an outercovering' for said products stretched by said liner over said products and holding the latter tautly in place,4 said liner consisting of a substantially at sheet of corrugated paper rectangular in form, said sheet having a major axis and a. minor axis substantially 90,to each other, the corrugations in said paper running substantially transverse to said major axis, and a crease line constituting a bending zone extending parallel to the major axis Y i at or nearthe mid-point of said minoraxis, the areas on either side of the crease line being relativelyrigid in a direction transverse to the major axis, the width of said liner alongfits minor axis being such that when in place in saidpackage the liner stretches the outer covering over prod-- ucts supported between the liner and said covering.
