` PACKAGE Filed Nov. 28, 1956 Patented July 19, 1938 UNITED STATES PATENT GFFI'CE PACKAGE Walter E. Weeks, Baltimore, Md.

Application November 28, 1936, Serial No. 113,114

8 Claims. (Cl. 20S-46) The invention relates" to a package for loose particles of food as nut kernels or meats, candies or small cakes and the like, in and by means of which the food particles are attractively displayed and at the same time are protected from deterioration by the action of air, moisture and other harmful agencies and protected from crushing and breakage. While the package is primarily a food package, it may be used for other small articles.

The package comprises a bag or other sealed Wrapper preferably a tubular section of transparent sheet material which is Water resistant and may be to a large degree water proof. This 15 material is to the best advantage capable of sealing by heat though materialsotherwise sealed may be employed. While moisture resistant material is preferred, other transparent materials may be used.

The material which has been used for this purpose inthe practice of applicants invention is cellulose hydrate in the form of sheets which are flexible, transparent, non-absorbent and highly resistant to the action of water and also selfadhesive under the action of heat so that it is easily sealed by heating without the use of a separate adhesive.

The bags may be filled and sealed in accordance with the method described in United States 30 Patent #1,986,422 or in any suitable manner, the bag or inner package being preferably at or capable of flattening. In accordance with the method of the patent, a strip of Sheet cellulose derivative of the kind described or any suitable kind of material is bent laterally into tubular form about a feed tube which feeds the food particles into the transparent wrapping tubeas it is formed. For convenience, this wrapper material may be referred to as Cellophane, it being understood however that this word Cellophane is a trade-mark applied to the product of one manufacture and that other sheet materials of this character may be used for this purpose. The tube is sealed longitudinally and is also sealed transversely and cut at the center of each transverse seal so as to form a series of closed lled bags, each having flattened portions at its ends where the front and back of the bags are joined by sealing.

In accordance with the present invention these bags which when unprotected or unsupported are subject to breakage by bulging with-the consequent spilling of the contents, and are also lacking in protection for the food product which is apt to becrushed and broken in handling are well protected. Also these bags in the unsupported form are shapeless and not adapted for quick and easy handling or for packing uniformly in quantities.A

In accordance with the present invention, these filled bags or packages are given a uniform shape and supported and protected from bulging by means of a paper or other relatively stiff opaque envelope or backing which is quickly applied and inexpensive and which exposes the food product in an attractive manner for exhibition an-d examination.

This wrapper is easily and cheaply applied and of attractive appearance and provides conveniently for the display of advertising matter in connection with the product, and the package as completed has the further important advantage that the food product does not come in contact With-the paper backing at any point so that there is no absorption of grease by the paper with the dlspleasing appearance of greasiness and discoloration and no loss of the food constituents by the absorbent properties and porosity of the paper which are unavoidable incidents to other paper wrapping or backings. In the accompanying drawing,'I have illustrated a package embodying the features of the invention in the preferred form. In the drawing:

Figure 1 isl a plan view of the paper blank which forms the backing or outside Wrapper, the same being flattened for purposes of illustration.

Figure 2 is a plan View of the bag or inside wrapper of transparent sheet material containing the food product ready for the backing.

Figure 3 is a fragmentary view of the backing partially folded, i. e. having one side ap folded, the unfolded iiap being also shown in broken lines in the flat position.

Figure 4 is a .top plan view of the completed package.

Figure 5 is a side elevation of the same, looking at the long side of the package.

.Referring to the drawing by'munerals, each of which is used to indicate the same or similar parts in the different figures, the bag or Wrapper A in which the food product is initially enclosed, indicated by reference character I has in practice been composed of cellulose hydrate which is self-adhesive when heated and therefore capable of sealing by heat without any additional adhesive, other cellulose derivative as cellulose acetate may be substituted being sealed by means of an adhesive or a solvent.. 'I'hese materials are highly resistive to Water and non-absorbent, other transparent sheet materials which have joined and sealed at 3.

pose. The inner package indicated by reference character I is sealed at the ends where it is flattened, the two layers of the transparent sheet adhering at I". The longitudinal edges are also The details and manner of joining, closing and sealing the inner wrapper and package may be widely varied. 'I'he bag or inner wrapper I, while it protects the food from' deterioration by moisture and the action of air and other agencies, is soft and the package I' lis shapeless being subject to breakage by bulging and it does not protect thefood product from crushing.

,This bag or= envelope is protected and supported and still retains its facility for displaying the product when partially enclosed within a toughl paper or other backing in accordance with the invention. This backing is shown flattened y or spread out in Figure 1, being indicated by reference character 2. The backing as shown is elongated or oblong, the package being likewise of oblong form and is creased at each side at 5 in parallel with the outside edges 6. It is also creased transversely at the ends at I in parallel with the end edges 8, the creases 'I being preferably spaced inwardly from the end edges 8 by a distance considerably greater than the distance of the creases 5 from the edges 6, the creases 5 and 'I cross near the corners at 9 and to contribute to the neatness of the ypackage and to decrease spondence with the dimensions of the inner package I" or bag I as filled but slightly greater to facilitate the closing of the flaps of the backing and the fastening of the bag I within the backing 2. The outline of the bag is shown in dotted lines in Figure 4, the edges of the bag being indicated by reference character 4. l

In the practice of the invention to date while the bags are formed and filled by means of an automatic machine, the nal wrapping operation, i. e. the enclosing of the bag in the backing 2, has been performed by hand. In this operation the blanks being provided cut and scored as shown in Figure 1 and properly printed with the advertising matter desired, are spread iiat on the work table as shown in Figure 1. A corresponding inner package or lled bag I is then placed on the flat blank, the edges 4 of the bag beingrelated to the scores"5, 1 substantially as indicated in dotted lines in Figure 4.` The side flaps I I are then folded inwardly over the edges 4- of the inner package about the scores 5 and the end aps I5, I 5 are then folded inwardly over the ends of the bag and over the ends of folded flaps I4, after which the package is stapled at I2 at each corner, the staples preferably passing each of them rst through the flaps I5 near the corners I6 and then through the flaps I4, then through the corresponding corners of the bag, i. e. through the ends of sealed flat portions I and nally through the main body I'I of the backing so that the backing 2 is not only secured about the back of the inner package and over the edges of the package but the bag is definitely fastened 2,124,824 the desired properties may be used for this purat its corners or at other convenient point within the backing.

It is of interest as to the ilnished package that the package is stiifened and the product thereby protected,- also the package is given a ilat rear or 5 bottom surface being thus rendered of uniform shape for convenience in packing in quantities.

, The product is most attractively displayed at the front where the bag or inner wrapper I and its contents bulge forwardly as shown at I8 and fully protected from contact with the paper and consequentdiscoloration of the paper and deterioration of the product from this source and from exposure to air, moisture, germs and dirt. The method of wrapping described also has the advantage of 1.,

simplicity, cheapness and speed being also adapted for performance by automatic machinery if desired. Itis of further advantage that the method of wrapping provides for advertising display on the back of the package on the outside, on the body of the backing on the inside behind the product, and above and below the product and alsoon the front as to the flaps or edges of the wrapper.

I have Ythus. described specifically and in detail a package embodying the features of my invention in order that the manner of constructing, applying, operating and using the invention may be fully understood. However, the specific terms herein are used in a descriptive rather than in a limiting sense, the scope of the invention being defined inthe claims.'
