11 Claims. (Cl. 206-46) My invention relates to an improved display wrapper package for food commodities such as sliced bacon and the like.

One of the objects of my invention is to pro- 'vide a novel package or wrapper for food commodities, such as sliced bacon, whichare characteristically limp and irregular in form and difficult to handle and wrap in a manner which will properly display them and at the same time completely enclose and protect them.

Other objects of my invention will appear hereinafter.

The accompanying drawings illustrate my invention as embodied in several modifications of packaging forms or wrappers.

, It is desirable in wrapping food or other articles that a substantial portion thereof be exposed through the wrapper for display purposes, and for this reason I utilize a thin flexible sheet of suitable. transparent wrapping material 1 such as cellophane, for the display portion of the wrapper, which in the completed package exposes a substantial portion of the article to view. In fact, with my improved wrapper, practically the whole area of one side or face of the completed package is formed by the transparent portion 1 of the wrapper. The flexible sheet of cellophane is preferably rectangular and is somewhat longer and wider than the article 2 to be wrapped, so that the portions which project beyond the ends of the article form and flaps 3 which are folded completed package 4 and 5 are folded over over the ends of the article as shown more particularly in the sectional view Fig. 2. The sheet of cellophane is laid out flat and the article 2, such as the group of slices of bacon, placed thereon in the central portion thereof. While wrapping the article the cellophane sheet is laid fiat on a table and is on the bottom of the package, but when the package is completed and turned over, the cellophane portion becomes the top or display side of the package.

In the form shown in Figs. 1 to 4, there are provided two rectangular strips or sheets 4 and 5 of relatively stiff material such as cardboard which provides stiffness or rigidity and regularity of form to the completed package. These strips in the form shown in Figs. 1 to 4 are separate pieces, but in the modifications in Figs. 5 to 12 they are cut from a single sheet of material and connected by integral cross-connecting portions, as will be hereinafter described.

These strips are preferably rectangular in shape and are preferably made substantially the length andrwidth desired for the completed package because, in a sense, they determine these dimensions when the wrapper is folded around the article. In the manufacture of the wrappenthese stiff backing strips are positioned to overlap the longitudinal marginal portions 6 of the cellophane sheet in parallel relation to the edges thereof the overlapping portions of the cellophane and stiff members being secured together by glue or any suitable adhesive. The edges '7 of the two strips are spaced apart on the cellophane sheet substantially the width desired for the completed package because these edges determine the lines along which the sheet 1 is folded in wrapping the article.

The manufactured wrapper comes to the operator as a fiat structure comprising the cellophone sheet 1 with the strips or flap members 4 and 5 attached as above described. The operator lays one of these wrappers on the tablein flat condition and places on the central portion thereof the slices of bacon or other article to be wrapped. The operator first folds the end flaps 3 of the transparent sheet over the end portions of the article, as indicated "n Fig. 2, using'theend edges 9 of the strips 4 and 5 to define the lines on which the folds of the flaps are made. After the end folds have been formed, the stiff flap members the top of the article, first one and then the other in superposed relation, the folds in the sheet 1 being defined by the edges '7 of said stiff members 4 and 5, as shown in Fig. 4. The folding of these flaps completes the enclosure of the food product in a package which completely protects the contained operator.

ing of the wrapper on the lines of these edges acts to always form a uniform package of the same definite width and length without the ex ercise of any particular skill on the part of the This is obvious because whether the folding is done manually or by means of folding mechanism, the relatively stiff edges 7 and 9 automatically cause the fold to take place on these lines.

In the event that the food article should extend beyond the area defined by the folding lines, the folding of the flaps will force or compress the article within the dimensions of the package. Thus a neat appearing package is always formed. The package is stiffened by the two layers of cardboard flaps 4 and 5 so that it can be handled as much as necessary and still retain its shape. The flaps 4 and 5 are preferably not sealed so that a portion of the contents can be removed and the remaining portion again wrapped by refolding the flaps.

It is desirable in a package of this character, to display the goods to the best avantage and for this reason it is desirable that the transparent portion of the wrapper, which constitutes the window for exposing the goods, shall lay smooth and unruilled. In my improved package this is accomplished very effectively in the folding of the wrapper for the reason that the package has no definite side faces but, in effect, has simply a front or top transparent face and a bottom or rear non-transparent face. On account of the thickness of the article, however, the flexible transparent portion of the wrapper is forced into curved formation. The backing flaps or members 4 and 5, being relatively stiff, are not curved in section to any great extent. Hence,

'when the flaps are folded, the curving of the cellophane causes it to tension or stretch transversely and this action lays the cellophane material flatly against and in intimate contact with the surface of the contained article. In the case of sliced bacon or similar products'which are wet or greasy, the cellophane material adheres intimately to the article and because of its transparency it does not show, but the food article appears in a natural uncovered condition. In this manner the character of the product is very effectively displayed. In addition to this, the pressing of the meat or other product into intimate contact with the cellophane excludes air from the exposed face of the meat and preserves this exposed face against deterioration for a relatively long period of time thereby maintaining the fresh and attractive appearance of the meat as it was originally packed.

While the stifl backing flanges 4 and 5 may be maintained in flat condition in the package, it is preferable that these members spring slightly out of a flat plane in the completed package in order to improve its appearance and form. Several score marks 13, spaced apart and arranged parallel longitudinally of the package may be provided in the faces of the stiff members whereby in the folding of the flaps they will bend slightly along these score marks as indicated in Figure 4.

The outer faces of the stiff backing flaps 4 and 5 provide space upon which advertising matter may be placed, but it is desirable that a label of some character he provided on the display face of the package. In the structure shown in Fig. 1, this may be accomplished by the provision of a separate thin label 12 indicated in 1 dotted lines. The label may be placed trans- .terial before the versely upon the surface of the cellophane mabacon is placed thereon. en the wrapper is folded up, this label will also be stretched tightly across the displayed face of the product and will appear through the cellophane material when the package is completed.

The structures from the structure of Figs. 1 to 4 Just described, principally in the fact that the flap members 4 and 5 are connected by integral cross members. This has an advantage over the structure of Fig. it, particularly in the manufacturing of the wrapper for the reason that the cross-connecting members tie the two side flaps together and enable them to be die-cut from a single sheet of material, and in the assembling operation enables one piece of cardboard material to be handled instead of two separate flap members.

In the structure shown in Figs. 5 to 8, this cross member 14 is preferably transversely positioned midway of the length of the package and provided with suitable area upon which advertising matter such as the name of the manufacturer may be placed. This advertising matter 15 may be printed directly on the cross-connecting member 14 or a separate label may be attached to this member during the process of assembling the wrapper.-

In the structure shown in Figs. 9 to 12, there is provided, in addition to the central cross member 14, end connecting portions 16 which are likewise formed integrally with the flap members. These end connecting portions together with the marginal portions 17 of the flap members have the effect of providing a window frame on the display side of the package. In order that the marginal portion 17 will remain on the display face of the package when the wrapper is formed, the flaps are made wider and provided with score lines 18 for folding purposes. The score lines 18 correspond to the marginal edges 7 of the structure of Fig. 1 in determining the lines on which the flaps will be folded. Thus, when the wrapper is folded in the same manner as that described in connection with Fig. 1, the

window-framing remains on the display face of the package as shown more clearly in Figs. 11 and 12. The flaps 4 and 5 in other respects function in the same manner in forming the back of the package. The advantage of this structure over that of either Figs; 1 to 4 or 5 to 8 lies in the fact that the exposed portion of the product is set-off trimmed by a frame which conceals the appearance of the ragged edges, particularly at the ends of the contained product.

It is apparent from the disclosures herein made that the structures embodying my invention are capable of changes in the construction and operation of the parts without departing from the spirit of the invention, and I contemplate such changes as fairly of the appended claims.
