Claims.

This invention is for improvements in or relating to the wrapping of block shaped articles, and refers to wrappers of the type in which a wrapper 'is formed from a substantially rectangular and 5 readily foldable blank, which blank when placed about the article to be wrapped encloses two pairs of opposed faces of the article the end portions of the wrapper being arranged to overlap.

According to the present invention there is l0 provided a wrapper of the type described wherein one end portion of the wrapper is slit to provide a tongue the slit end portion being undermost when the end portions of the wrapper blank are overlapped, and wherein the tongue is folded against the wrapper blank to protrude between the said overlapping ends (e. g. to extend beyond a face of the article), whereby the tongue may be gripped to facilitate the removal of the wrapper from the article. The wrapper may be weakened (e. g. slit) adjacent the tongue.

The ample with reference to the 'accompanying drawing in whichz- Fig. 1 shows a blank from which the wrapper is to be formed. I

Figs. 2 to 5 show various stages during the folding of a Wrapper blank about an article.

Fig. 6 shows an alternative form of wrapper.

Like references refer to like parts throughout the specification and drawing.

Referring to Figs. 1-5 one end portion of the wrapper blank 'l is provided with two slits 8 which extend from an edge of the Wrapper blank in the direction of the length of the blank thereby forming a tongue 9. The wrapper blank is folded into a U about the article to be wrapped, the limb l0 of. the U being of a length substantially equal to the length of the article being wrapped, whilst the other limb of the U extends beyond that face of the article which is opposite the face about whichv the U is formed. The end portionof the longer limb of the U is folded about that face of the article which is opposite the face about which the U is formed so that the extreme end portionof the longer limb of the U is folded against that face of the article whichis engaged by the limb I0.

. The tongue portion 9 is folded backwardly upon the wrapper blank so that the tongue extends beyond that face of the article opposite the face about which the U is formed. The limb l0 is folded into engagement with the end portion Il and secured thereto by any suitable means such, for example, as adhesive, or if the wrapping material is made from a cellulose derivative then invention will be described by way of ex Great Britain October 18, 1935 it may be secured by a suitable cenulosic solvent. The limb Ill when folded into engagement with the end portion l l also covers a part of the folded tongue 9, as `can clearly be seen 4 and 5.

The tongue portion 9 is folded about a fold from Figures 3,

line I2, and normally the slits 8 terminate atv the line l2. If, however, it is desired to provide tear starting slits further to facilitate the removal of the -wrapper fromabout an article, then the slits are extended beyond the line l2 in the manner illustrated in Fig. l, or, if desired, the tear starting slits are disposed adjacent the tongue 9. In each case, however, the tear starting slits lextend in the general direction of the length of the wrapper blank, that is, in a 'direction-.transverse to the edge of the slit end portion of the blank.

Thewrapper is completed by firstV folding inwardly the narrow side folds i3 at the ends of the wrapper and thereafter folding into. engagement with each other the side folds M and I5.A

The side folds of the wrapper are secured together in any suitable manner such, for example, as those referred to above.

Referring to Fig. 6 the wrapper shown therein is a wrapper of the well known block ended type, and the wrapper is provided with a tongue 9 in a manner similar to that described above. The wrapper blank is, however, in the embodiment of the invention shown in Fig. 6 folded in the well known manner by means of which a block ended wrapper is obtained.

The tongue may be arranged to project be-zyond a face of the article, as shown in Figs. 2-6 of ,the drawing, or if desired the tongue may be again folded so that it is in engagement with the limb l0 in the construction shown in Figs. 1 5, or, so that it engages with the outer closureap 1,6- of the construction shown in Fig. 6. Alternatively, the length of the tongue may be such that whilst it projects from between the overlapping end portions of the wrapping material it does not project beyond a face of the wrapped article. In this latter construction the tongue must of course project sufficiently to enable lt to be gripped when it is desired to open the wrapper.

It will be appreciated that the tongue portion n than itis to the other side, as

What I claim as my invention and desire to secure by Letters Patent is:-

1. A wrapping comprising a substantially rectangular wrapper, said wrapper being folded so as to enclose two pairs of opposed faces of an article with-a pair of opposite end portions of the wrapper overlapping, that end portion which is below the other being provided with a tongue, said tongue being folded so as to protrude from between the overlapping end portions to provide a ngerhold to facilitate the removal of the wrapping from about the article contained therein.

2. A wrapping comprising a substantially rectangular wrapper, said wrapper being folded so as to enclose two pairs of opposed faces of an article with a pair of opposite end portions of the Wrapper overlapping, that end portion which is below the other having slits to provide a tongue, said tongue being folded so as to protrude from between the overlapping end portions to provide a nngerhold to facilitate the removal of the wrapping from about the article contained therein.

3. A wrapping comprising a substantially rectangular wrapper, said wrapper being folded so as to enclose two pairs of opposed faces of an article with a pair of opposite end portions of the wrapperoverlapping, that end portion which is below the other being provided with a tongue, said tongue being folded so as to, protrude from be- -tween the overlapping end portions to provide a ngerhold to facilitate the removal of the wrapping from about the article contained therein,

said wrapper being weakened adjacent the tongue further to facilitate the removal of the wrapping.

4. A wrapping comprising a substantially rectangular wrapper, said wrapper being folded so as to enclose two pairs of opposed faces of an article with a pair of opposite end portions of the wrapper overlapping, that end portion which is below the other being provided with a tongue, said tongue being folded so as to protrude from between the overlapping end portions to provide a flngerhold to facilitate the removal of the wrapping from about the article contained therein, said wrapper having slits adjacent the tongue further to facilitate the removal of the wrapping, said slits extending in the general direction of the wrapper.

5. A mapping comprising a substantially rectangular wrapper, said wrapper being folded so as to enclose two pairs ofopposed faces of an article with a pair of opposite end portions of the wrapper overlapping, that end portion which is below the other having slits to provide a tongue,

said tongue being folded so as to protrude from between the overlapping end portions to provide a ngerhold to facilitate removal of the wrapping from about the article contained therein, said slits extending beyond the line about which the tongue is folded further to facilitate the removal of thewrapping.
