This invention relates particularly to wrappers of the kind employed in wrapping bread and similar products, although it will be readily adapted to the wrapping of many other articles. Among the 0 jects of my invention are the provision of a wrapper which will allow the wrapped article to be repeatedly withdrawn and replaced and thus better reserve the contents after it has been opene Still another object of the invention is to provide a roll of improved wrapping material from which individual wrappers may be formed. Other objects and advantages will be apparent from the specification and drawings.
Referring to the drawings which form a part of this specification and illustrate a preferred form of my invention;
Figure 1 is a perspective view of a loaf of bread wrapped in accordance with my invention, the wrapper having been expanded for a portion of its length to allow withdrawal of the loaf.
Figure 2 is a perspective view of a single wrapper.
Figure 3 is in Figure 2.
Figure 4 is a perspective view of a roll of wrapping material embodying my invention and from which the single wrapper shown in Figure 2 might be formed.
The wrapper 12, preferably of the usual waxed paper is wrapped around the loaf 10, its ends bein held in sealed relation at 14. A leat is ormed in the sheet 12, the folds o the pleat being held temporarily together by solidified wax or other suitable adhesive. be obtained in any suitable manner, but a simple and expedient manner of accomplishing this consists in melting the wax at the fold and allowing the wax to solidify while the paper is held folded.
The pleat formed in the wrapper is preferably positioned longitudinally of and at the top of the loaf as shown 1n Figure 1,
an end view of'the sheet shown after which the wrapper is formed about the loaf of bread and sealed together in the usual manner.
The form in which the wrappers would wrappin The adhesion of the folds may of extensib ordinarilybe sold is shown 'by Figure 4, where a roll-ofwrapping material 12 is formed with a plurality of spaced apart pleats 16,) thedistancebetwe'e'n adjacent pleats being not greater than the length of the individual wrappers to be formed from the web. Forusewith certain types of or sheet immediately before the wrapping operation, using for this purpose suitable folding mechanismewhich mi ht be incorporated in the wrapping mac ine. f
In use, one end only of the wrap er'wi'll be undone in the usual manner and t e 'pleat 'may be, unfolded or expanded by exerting aaslight tension onthe paper-lying on each side-of the pleat. This will sufiicientlyenlarge the-wrapper for'the loaf to be readily removed from the wrapper without tearing the wrapperor unsealing the'sealed portion 14; -After cutting the desiredquantity of bread the loaf may 'be replaced and the unmachines however, it would be more desirable to form the pleats in the Web to v out with any kind of paper or other material from which wrappers might be formed, and that other suitable adhesives might replace the wax to hold the pleat in folded relation, and although the pleat is the preferable form e portion, other extensible means might be found equally asuseful.
The wrapper will also be found useful for wrapping many other objects besides bread, cake, etc., and can easily be adaptedto the wrapping of any article which it might be advantageous to remove from and replace in its original wrapping. I therefore do not air-tight wrapper, extensible portion wish to be limited to the exact form shown and described, but only by the following claims.
What I claim and desire to secure by Letters Patent is:
l. A wrapper comprising a sheet of relatively impervious material adapted to be wrapped "around a prismoidal object, said wrapper being provided substantially intermediate its ends with an extensible portion 7 extending longitudinallyof the object to be wrapped, and releasably held against extension by an adhesive whereby the object can be readily removed from and replaced within the Wrapper when extended without destroying the continuity of the wrapper. I
2. ikwrapped article comprising a prismoidal object enveloped by asubstantially said wrapper having an releasably' heldv against extension and [extending longitudinally of the wrapped object, whereby the girth of thewrapper can be increased to loosen the wrapper without destroying the continuity of the wrapper, thereby allowing the body to be readily removed from and reinserted within the extended wrapper.
3.'A wrapper for perishable articles ineluding a sheet of substantially im ervious material only slightly longer than it I of the article to vbe wrapped, an extensible portion intermediate theends of the sheet, means for temporarily and adhesively securing the extensible portion of the wrapper in unextended condition, whereby the wrapper after being tightly enveloped around the body to be wrapped can be increasedin girth without destroyin thecontinuity of thewra per as wrapped or the repeated removal rom and reinsertion of the body within the expanded wrapper. I
In testimony whereof I have aifixed my signature. 7 I I i HORTEN R; DURHAM.
