Application November 28, 1936, Serial No. 113,114 ` _ 8 Claims. 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 dis 5 played 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 10 small articles. The package comprises a bag or other sealed Wrapper preferably a tubular section of trans parent 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 ma terial is preferred, other transparent materials may be used. The material which has been used for this pur 20 pose in- the practice of applicant’s 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 self adhesive 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 accord ance with the method described in United States 30 Patent #1,986,422 or in any suitable manner, the bag or inner package being preferably ñat 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 par ticles into the transparent wrapping tubeas it is formed. For convenience, this wrapper ma terial may be referred to as Cellophane, it being .40 understood however that this word Cellophane is a trade-mark applied to the product of one man ufacture and that other sheet materials of this character may be used for this purpose. The tube is sealed longitudinally and is also sealed s. Ui transversely and cut at the center of each trans 3 verse seal so as to form a series of closed ñlled --bags, each having flattened portions at its ends where the front and back of the bags are joined by sealing. 50 In accordance with the -present invention these bags which when unprotected or unsupported are subject to breakage by bulging >with-the conse quent spilling of the contents, and are also lack ing in protection for the food product which is 55 apt to be’crushed and broken> in handling are (Cl. 20S-46) well protected. Also these bags in the unsup ported form are shapeless and not adapted for quick and easy handling or for packing uni formly 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 10 in an attractive manner for exhibition an-d ex amination. This wrapper is easily and cheaply applied _and of attractive appearance and provides conven iently for the display of advertising matter in 15 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 20 dlspleasing appearance of greasiness and discol oration and no loss of the food constituents by the absorbent properties and porosity of the pa per which are unavoidable incidents to other paper wrapping or backings. In the accompany 25 ing drawing,'I have illustrated a package em bodying the features of the invention in the pre ferred form. In the drawing: Figure 1 isl a plan view of the paper blank which forms the backing or outside Wrapper, the 30 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 35 partially folded, i. e. having one side ñap 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. ' 40 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 prac tice been composed of cellulose hydrate which is self-adhesive when heated and therefore capable of sealing by heat without any additional adhe 50 sive, other cellulose derivative as cellulose ace tate may be substituted ‘being sealed by means of an adhesive or a solvent..
