' INVENTOR.\ LOUIS D. Freiberg BYWIE Patented Mar. 20, 1945 UNITED sTATE 2,311,985 I a WRAPPED ARTICLE AND METHOD OF WRAPPING THE SAME Louis D. Freiberg, Akron, Ohio a Application February 8, 194 3,'Serial No; 43,188 1 4 Claims.

This present invention relates to packaged moisture containing articles and to procedure for producing the same. r i

Heretofore, many articles usually purchased in grocery stores such as meat, fillets, chops, cuts, and steaks thereof, whole fish, fillets, and steaks thereof, mm or game, whole, or Joints thereof, citrus fruits, tomatoes, grapes, cakes of soap and many other articles containing iroisture which is present at and may evaporate from the surface thereof have been provided with envelopes or wrappers of various sheet materials of the'nature of waxed paper, Cellophane, Pliofilm, Koroseal and other tough flexible transparent or translucent materials, in some cases, as in the case of Cellophane bags or envelopes, being sealed to prevent loss of moisture from the packaged article.

Sealing of such bags or envelopes necessitates the use of adhesives applied locally to the bag or envelope along flaps or margins thereof and involve manufacturerof the bag or envelop, insertion of the moisture containing article theren, and finally sealing by the use of adhesives or adhesive tapes appliedat the mouths of the bags or envelopes.

It has been discovered by the present inventor that sheet materials sucha Cellophane, Pliofihn,

, Koroseal, etc., which are tough, flexible, and

transparent and are coated with water-repellent, permanently-tacky, pressure-sensitive, clear adhesives of a known type applied over one face thereof and which materials are on the market as Scotch tape or other trade names are capable of highly advantageous use a wrappers for the previously enumerated articles. While this sheet material is strongly adhesive to itself wherever laps, crimps, or. folds of the material are pressed together with at least one layer of the adhesive;

coating between the abutting faces of the sheet material, because of the character of the surfaces of the article such as those enumerated and the presence of more or less moisture therein, the

tacky water-repellent adhesive will not adhere str'ongly,-anc l in many cases will not adhere at all to surfaces of the articles against which it maybe pressed, and will peel readily away from the article when the wrappers of suchmaterial are being removed.

In carrying out the present invention, toughflexible transparent material havinga clear'adhesive coating of the kind described is merely wrapped and lapped in any convenient way about the article with the'adhesive face against the article and projecting margins thereof are crimped or folded to bring adhesive faces of the about the article which may. inevitably be entrapp d. Articles such as citrus fruits, meats, fish, fowl,

aged, expecially ifkept refrigerated, keep substantially all of their original water content, vitamins, and palatability without desiccation, putrefaction or decay and for indefinite periods of time,

l5 and do so without requiring the use of ice refrigeration.

mechanical refrigeration,'etc., have no appreciable dehydrating or other effect upon the contents of the packages.

Fillets of meats, fish, etc., have heretofore had ordinary sheet wrappers of Cellophane or the like applied about them but have required ice refri'geration for their preservation. By use of the present invention-this expensive and troublesome 26 icing may be avoided, dry refrigeration being entirely satisfactory.

The packages are, of course, complete germ and vermin proof, and thus not onlypreserve the. moisture within the article, but prevent ingress of i dirt and "foreign matters of all kinds;

I The packages, being transparent permit handling as well as visual inspection to note the Weight, feel, color, and texture of theipackaged,

contents without danger of contamination. v For purposes of illustration of the invention, there is shown in the accompanyingdrawing an orange being packaged in accordance with the present invention.

" herein may be different articles containing moisture present at surfaces thereof which comprises orange as indicated in Figure 2 with over-lapping margins of the sheet pressed together, and finally the projecting portions of the wrapper are crimped and pressed snugly against the surface of the orange, the folds or crimps adhering to To remove the wrapper it may be cut and readily peeled from the orange, or a thread or band (not shown) as is well-known in the art of packaging, may be incorporated in the wrapper. a projecting end of which may be grasped and pulled to sever the wrapper.

It will be apparent that the invention disclosed applied in the packaging of many their surfaces and of a surfac texture such that the adhesive will not adhere to the surface of the article or will only slightly adhere. The invention is operable in thismanner with .many different articles of similar surface characteristics to those specifically mentioned.

Modifications of the invention may be resorted to without departing from the spirit thereof in the scope of the appended claims.

What is claimed is:

1. An article containing moisture which is mor I or less present at the surface thereof and having tough flexible transparent sheet material with a face 'coated with clear, permanently-tacky, pressure-responsive, waterrepellant adhesive wrapped snugly about the article with the adhesive-coated face applied against the article, said wrapper crimped or folded about the article so as snugly to encase the same with the laps and crimps or folds pressed together whereby the adhesive seals the wrapper about the article completely to seal the article therein, said adhesive having little or no adherence to the surface of the article so that it may be readily peeled therefrom'to remove the wrapper, and said wrapper containinglittle' or no air excepting that which may'inevitably be entrapped during the wrapping process;

2. That method of packaging moisture-containing articles having moisture-present at the applying a sheet of tough flexible transparent material having a thereon a wrapper of permanently tacb', water-repellent, pressure-responsive adhesive on oneface thereof about the article with said adhesive-coated face against the surface of the article and lapping and crimping or folding the wrapper snugly about the article while pressing the laps and crimps or folds together so as snugly and completely to encase the article with exclusion of all air excepting such small quantities as may be entrapped during the wrapping process.

3. An article containing moisture which is more or less present at the surface thereof and having thereon a wrapper of tough flexible transparent sheet material with a face coated with clear,

permanently-tacky pressure-responsive, waterrepellent adhesive wrapped snugly about the article with the adhesive-coated face applied against the article, said wraper having its overlapping margins adhesively secured together and then being lapped and crimped or folded about the article so as snugly to encase the same with the laps and crimps or folds pressed together whereby the adhesive seals the wrapper about the article completely to seal the article therein, said adhesive having little or no adherence to the surface of the article so that itmay be readily "peeled therefrom to remove the wrapper, and

being lapped and 5 said wrapper containing little or no air excepting that which may inevitably be entrapped during the wrapping process.

4. The method of packaging moisture-containing articles having moisture present at the surfaces thereof which comprises applying a sheet of tough flexible transparent material having a permanently-tacky, water-repellent, pressure-responsive, adhesive on one face thereof about the article with said adhesive-coated face against the surface of the article, overlapping opposed marginal portions of the sheet and adhesively securing the overlapped portions together, and lapping and crimping or folding the wrapper snugly about the article while pressing the laps and crimps or folds together so as snugly and completely to encase the article with exclusion of all air excepting such small quantities as may be entrapped during the wrapping process.
