- UNITED STATES OSCAR W. WENTZ, OF NEW YORK, N. Y.

WRAPPER.

Application filed April 13, 1921. Serial No. 461,030.

To all whom it may concern:

Be it known that I, OSCAR W. WENTZ, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in ,l/Vrappers; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

i This invention relates to wrappers particularly adapted for inclosing newspapers,

magazines, circulars, drawings, or other books or papers which may be rolled into cylindrical form.

It is the usual practice in wrapping an article of this character for I transmission through the mails or for other purposes to roll and then wind tightly about it one or more convolutions of paper of sufficient strength to resist tearing. The outer edge of the wrapper is secured to the portion thereof immediately beneath, and the tendency of the article to unroll adds to the security with which the wrapper is held in place.

On account of the tightness of the wrappers difliculty is usually experienced in quickly and easily opening packages of this character particularly without the use of a knife or paper cutter for slitting the wrappers. It frequently happens that the edges of the pages of the article become torn or otherwise mutilated while the wrapper is being removed, and if a knife is employed there is danger of slitting the article as well as the wrapper.

Various arrangements have been proposed for overcoming the disadvantages mentioned above such as the provision of a cord or the like which is placed beneath the wrapper so that the latter may be severed by drawing the cord through it from one end of the package to the other, or the provision of a weakened line running longitudinally of the package and'which is made by perforats ing or otherwise cutting the wrapper so that it may be easily torn along this line. The first named arrangement adds to the cost of the wrapper, while the second arrangement may weaken the wrapper to such an extent that it may become torn accidentally during transmission or by handling of the package before it reaches its destination.

It is an object of this invention to provide a wrapper for articles which may be rolled into cylindrical form, which is cut so that it may be quickly and easily severed and removed without the use of instruments and which when in place will possess the strength of a continuous sheet of paper, thereby preventing any danger of the package opening accidentally.

In accordance with the invention the wrapper-blank is provided with a plurality of parallel slits or series of perforations which are so arranged that when the wrapperis wound about a rolled article they will extend substantially at right angles to the axis of the roll thus producing a series of transverse straplike portions of the material integrally connecting continuous portions thereof. These straplike portions will ordinarily subtend a relatively small arc of the circumference of the package and will lie flat against it until displaced by twisting the ends of the package in opposite directions. When this occurs the edges of these portions will be slightly raised from the article and separated from each other so as to permit them to be caught and torn by running the thumb or finger along the package.

The particular nature of the. invention as well as other objects and advantages thereof will appear more clearly from a description of certain preferred embodiments as shown in the accompanying drawings in which,

Fig. 1 is a wrapper of one form,

Fig. 2 shows the wrapper in place upon a rolled article,

Fig. 3 is another form of wrapper that may be used, and

Fig. 4 represents another modification.

The wrapper shown in Fig. 1 consists of a blank 1 preferably of paper and provided with a plurality of parallel slits 2 between which are portions 3 adapted when the wrapper is wound about an article 4 to extend at right angles to the axis of the package as shown in Fig. 2 The slits may be of any desired length and number and placed at any suitable part of the blank. When the wrapper is in place the portions 3 will act as straps between the non-slit parts with which they are integral, and since they extend circumferentially of the package they will resist the tendency of the article to unroll as much as do the. continuous parts so that there is no danger of their giving way.

When it is desired to open the package the ends may be grasped in the hands and turned slightly in opposite ,directions. Thisg action willcause the portions 3 to be somewhat displaced from their normal position flat against the article so that their edges will be raised enough to be caught by a thumb or finger nail as it is run lengthwise of the package. The port-ions 3 may thus be easily torn to release the wrapper.

Instead of the simple narrow slits 2 as shown in Fig l the blank may be provided with wider slits .5 as shown in Fig. 4, or witlraplurality 01 series of perforations 6 as shown in Fig. 3.

or of'dif'ferent lengths as in-Fig. l, and, i'n'-' stead of being arranged to lie exactly at rightangles to the axis'of the package, they may be slightly inclined, desired; without weakening the strength of the Wrapper.

The slits or perforations maybe cut into the wrappers bya die or the like at the same time that the blanks are being cut to the requiredjsize, so that no extra operationsare, requiredand the cost of the wrappers not increased. 1

While the Wrapper will usually, be wound;

about the article with but one convolution "For the sake of economy, the portions 3 may be severed equally well if they lie upon a lower convolu'tionof the wrapper insteadof upon the article itself.

Certainpreferred embodiments of the in ventio'nhave been shown and described, but

In all cases the'slits may beeither of the same length as in'jFig l I axis of the package'when the; wrapper is inplace.
