Abstract
A wrapping blank of paper or plastic film for a cuboid soft pack for cellulose tissues or the like has a rectangular zone (1) for the production of the narrow sides (7, 8), the face and the back (6) as well as of the bottom (9) of the soft pack. Further, a closing flap (13) is provided, which is integrally formed on the rectangular zone (1) and which covers a removal opening formed by a cutout (15) of the soft pack in the latter's closed condition. The free lateral edge of the closing flap (13) and the cutout (15) are formed by a common, substantially sinusoidal edge of cut (16) of continuous run free from corners and misalignments, the convex section (17) of which defines the closing flap (13) and the concave section (19) of which defines the cutout (15).
Description
WO 96/36481 pGT/US96/05542 . EASY OPENING HANKY PACK/iIAVE CDT
The invention relates to a wrapping blank of paper or plastic film for a cuboid soft pack for cellulose tissues or the like comprising the features specified in the preamble of patent claim 1 as well as a method for the production of such a wrapping blank.
Cellulose tissues, for instance handkerchieves, but also other kinds of tissues, such as facial tissues, cleansing tissues and the like, mostly come in certain quantities, for instance in the number of ten, to form packs. The corresponding soft pack consists of a wrapping blank of pa-per or plastic film, serving various purposes. At the manufacturer or the retailer, it is the object of the wrapping to protect the contents from soil. When the pack is used, the wrapping must be easy to open so that the contents can be removed in as simple a manner as possible. This is accompanied by the demand for the wrapping to be reclosable after the removal of a tissue so that the remaining tissues continue to be protected from soil.
Of course, the manufacture of reclosable wrappings also poses an econom-is problem. Reclosability demands for a more complicated wrapping blank than this was the case with non-reclosable packs. With prior art wrap-ping blanks, as for instance specified by German utility model 75 39 076, it is in particular the closing flap, but also the cutout for the removal opening that require cuts causing waste in the production of the wrap-ping blank for the soft pack. Consequently, the manufacture of such packs gives rise to some material requirements. Further, the waste pro-duced during the manufacture of the wrapping blank must be removed permanently to avoid breakdown of the wrapping machine.

With prior art wrap-ping blanks, as for instance specified by German utility model 75 39 076, it is in particular the closing flap, but also the cutout for the removal opening that require cuts causing waste in the production of the wrap-ping blank for the soft pack. Consequently, the manufacture of such packs gives rise to some material requirements. Further, the waste pro-duced during the manufacture of the wrapping blank must be removed permanently to avoid breakdown of the wrapping machine.
DE 33 24 490 Cl discloses a wrapping blank of the species that can be
2 produced without waste from an endless web of film. The wrapping blank disclosed thereby is however accompanied by several disadvantages, re-sulting in the fact that this wrapping blank was not put into practice. For instance, the course taken by the cut to form the free edge of the closing flap and the cutout is extremely complicated, having sections of perpendicular design. As a result, there are problems in cutting the wrapping blank from a continuously conveyed endless web with the aid of conventional rotating cutting tools. Furthermore, the design of the wrapping blank results in that lateral flaps remain in the vicinity of the removal opening, which partially cover l0 the removal opening located at the front of the pack. This is uncomfortable when you want to take out the contents of the pack.
Proceeding from the problems explained, it is an object of an aspect of the invention to improve a wrapping blank of the generic type such that while keeping its characteristic of production free from waste, the blank can be cut without any difficulties in particular from an endless web with the aid of conventional cutting tools, while simultaneously being convertible into an optically pleasant soft pack offering the possibility of unimpeded removal.
Accordingly, the free edge of the closing flap and of the cutout constituting the removal opening of the pack in the folded condition is formed by a common, substantially sinusoidal edge of cut of continuous run free from corners and misalignments, the convex section of which substantially defines the closing flap and the concave section of which substantially defines the aforesaid cutout for forming the removal opening. As a result of the sinusoidal course of the edges of cut and their being free from corners and misalignments, the shape of the blank is of the most simple design in spite of the closing flap and the cutout realized thereby. In particular, it has no sectional cuts of perpendicular arrangement, which strongly complies with the mechanical cutting of the wrapping blank. Owing to the smooth and harmonious sinusoidal shape of the free edge, which lies open over its entire length in the opened condition of the soft pack produced with the aid of the wrapping blank, the

In particular, it has no sectional cuts of perpendicular arrangement, which strongly complies with the mechanical cutting of the wrapping blank. Owing to the smooth and harmonious sinusoidal shape of the free edge, which lies open over its entire length in the opened condition of the soft pack produced with the aid of the wrapping blank, the
3 soft pack is of an esthetically especially attractive design. Furthermore, due to the aforesaid sinusoidal shape, manufacture free from waste is still possible, since two wrapping blanks assigned to each other in pairs can be produced at a time by a common, substantially sinusoidal wavecut for the simultaneous production of the edge of cut from an endless web of paper or plastic film.
The wrapping blank helps create an esthetically especially attractive soft pack. Moreover, two identical wrapping blanks can be produced by the point symmetric design of the edge of cut during the cutting free from waste of two blanks assigned to each other in pairs.
A further embodiment serves to improve the esthetic overall appearance of the soft pack produced from the wrapping blank according to the invention. This will be illustrated in conjunction with the description of several exemplary embodiments.
Further embodiments provide alternative configurations of the wrapping blank according to the invention, which are suitable in particular for a broadside pack or a so-called "flat case" and in some cases serve to make the bottom of the soft pack more attractive optically.
In accordance with one embodiment of the present invention there is provided a method for the production of wrapping blanks from an endless web of paper or plastic film, each of said blanks having three lateral straight edges disposed at right angles and a sinusoidal edge, wherein two of the wrapping blanks at a time, assigned to each other in pairs, are cut free from waste from the endless web by a common, substantially sinusoidal wavecut for the simultaneous production of the sinusoidal edges and by straight cuts for the production of the lateral straight edges.

4 Further features, details and advantages of the invention will become ap-parent from the ensuing description of examplary embodiments of the sub-ject matter of the invention and the method for its production, taken in conjunction with the drawings, in which:
Fig. 1 is a plan view of a first embodiment of a wrapping blank placed flat, Fig. 2 is a partial plan view of an endless web of plastic film with cutting lines for the production of the wrapping blank according to Fig. 1 being drawn, Fig. 3 and 4 are partial plan views of endless webs by analogy to Fig.
2 showing alternative shapes of cutting lines, Fig. 5 is a perspective illustration of a soft pack for tissue handker-chieves produced with the aid of the wrapping blank according to Fig. 1, and Fig. 6 is a partial plan view of an endless web of plastic film with cutting lines drawn for the production of a wrapping blank, showing further alternative configurations of the wrapping blank.
In the wrapping blank of Fig. 1, which is designed for an upright pack, the actual contour is shown by thicker solid lines. The thinner solid lines mark the folding edges along which the wrapping blank can be folded around a pile of cellulose tissues to form the soft pack of Fig. 5.
As a matter of principle, the wrapping blank comprises a rectangular zone 1, which is defined by three lateral edges 2, 3, 4 disposed at right angles. In the folded condition, this rectangular zone 1 constitutes the . face 5, the back 6, the two intermediate narrow sides 7, 8 and the bot-tom 9 of the soft pack, which is in the form of a conventional block bot- ' tom. The lateral strips . IO extending along the two lateral edges 2, 4 in common form the one narrow side 8, the strips 10 being glued (for a pa-per wrapping blank) or welded (for a plastic film wrapping blank) in the vicinity of the overlap I1. The strip I2 extending in parallel to the lateral edge 3 forms the bottom 9.

As a matter of principle, the wrapping blank comprises a rectangular zone 1, which is defined by three lateral edges 2, 3, 4 disposed at right angles. In the folded condition, this rectangular zone 1 constitutes the . face 5, the back 6, the two intermediate narrow sides 7, 8 and the bot-tom 9 of the soft pack, which is in the form of a conventional block bot- ' tom. The lateral strips .

The strip I2 extending in parallel to the lateral edge 3 forms the bottom 9.
5 A closing flap 13 is integrally formed on the rectangular zone 1, cover-ing the removal opening 14 of the soft pack in the tatter's closed con-dition. The removal opening 14 is formed by a cutout 15 of the wrapping blank located beside the closing flap I3.
As seen in Fig. 1, the free edge of the closing flap 13 and the cutout 15 is formed by a common, substantially sinusoidal edge of cut 16 of con-tinuous run free from corners and misalignments. The term "sinusoidal" is not to be understood in the strictly mathematical sense, but means that the edge _of cut 16 comprises a convex section 17 followed by a concave section 19 - via a straight section 18 if required. From the starting point 20 to the final point 21 the edge of cut 16 must not have any cor-ners or misalignments, i.e. it must be of continuous and substantially smooth run. As seen in Fig. 1, the convex section 17 of the edge of cut 16 defines the closing .flap I3 and the concave section 19 defines the cutout 15 for the production of the removal opening 14. The straight section 18 defines a substantially triangular side tab 22 prolonging the narrow side 7 upwards (cf. Fig. 5).
Between the starting point 20 of the edge of cut 16 and the convex sec-tion 17 on the one hand and betweeir the concave section 19 and the final point 21 of the edge of cut 16 on the other hand, starting and final sec-tions 23, 24 of the edge of cut I6 are provided, which are of reverse curvature. As seen in Fig. 5, these starting and final sections 23, 24 overlap in the folded condition constituting the soft pack, the misalign-went of level of the starting point 20 relative to the final point 21 caused by the overlap 11 being reduced by the reverse . curvature of the starting and f nal sections 23, 24. This improves the optical appearance of the soft pack in particular in the opened condition shown in Fig. S.
As seen in Fig. 1, the free edge of the closing flap 13 and the cutout 15 is formed by a common, substantially sinusoidal edge of cut 16 of con-tinuous run free from corners and misalignments. The term "sinusoidal" is not to be understood in the strictly mathematical sense, but means that the edge _of cut 16 comprises a convex section 17 followed by a concave section 19 - via a straight section 18 if required. From the starting point 20 to the final point 21 the edge of cut 16 must not have any cor-ners or misalignments, i.e. it must be of continuous and substantially smooth run. As seen in Fig. 1, the convex section 17 of the edge of cut 16 defines the closing .flap I3 and the concave section 19 defines the cutout 15 for the production of the removal opening 14. The straight section 18 defines a substantially triangular side tab 22 prolonging the narrow side 7 upwards (cf. Fig. 5).
Between the starting point 20 of the edge of cut 16 and the convex sec-tion 17 on the one hand and betweeir the concave section 19 and the final point 21 of the edge of cut 16 on the other hand, starting and final sec-tions 23, 24 of the edge of cut I6 are provided, which are of reverse curvature. As seen in Fig. 5, these starting and final sections 23, 24 overlap in the folded condition constituting the soft pack, the misalign-went of level of the starting point 20 relative to the final point 21 caused by the overlap 11 being reduced by the reverse . curvature of the starting and f nal sections 23, 24. This improves the optical appearance of the soft pack in particular in the opened condition shown in Fig. S.
6 Further, the starting and final sections 23, 24 of the edge of cut 16 define a second side tab 25 of the soft pack lying opposite the side tab 22.
The overall course of the edge of cut 16 is designed such that the latter is point symmetric referred to its point of intersection S intersecting a wrapping blank central line M placed between the two parallel lateral edges 2, 4 of the rectangular zone 1.
As seen from Fig. 2, the production of these wrapping blanks from an endless web 26 is possible free from waste. ThP endless web 26 is fed in the conveying direction T to a cutting device (not shown), where two wrapping blanks 27, 2T at a time assigned to each other in pairs are cut by a common, substantially sinusoidal wavecut 29 for the simultane-ous production of the corresponding sinusoidal edge of cut 16 of the wrapping blanks 27, 2T as well as by straight cuts 30 in the broadwise direction B for the production of the corresponding lateral edges 2, 4.
The width of the endless web 26 is such that two copies can be produced side by side. If the width of the endless web 26 is correspondingly in-creased, the number of side-by-side copies produced may of course rise to four, six etc. In the example of embodiment according to Fig. 2, the lateral edge 3 of the wrapping blank 27, 2T is formed by the lateral edges 31, 32 of the endless web 26.
In the case of the exemplary embodiment of Fig. 3 illustrating the cutting of the wrapping blanks 27, 2'f from the endless web 26, the sinusoidal wavecut is produced substantially parallel to the conveying direction T as is the case with the embodiment of Fig. 2. In the em-bodiment of Fig. 3, the wavecut 29 is such that there are no starting and final sections 23, 24 of reverse curvature. Rather, a misalignment V
of the respective starting and final points 20, 21 of the wavecut 29 is ' provided for compensation of the difference in level between the starting point 20 and the final point 21 of the edge of cut.

The overall course of the edge of cut 16 is designed such that the latter is point symmetric referred to its point of intersection S intersecting a wrapping blank central line M placed between the two parallel lateral edges 2, 4 of the rectangular zone 1.
As seen from Fig. 2, the production of these wrapping blanks from an endless web 26 is possible free from waste. ThP endless web 26 is fed in the conveying direction T to a cutting device (not shown), where two wrapping blanks 27, 2T at a time assigned to each other in pairs are cut by a common, substantially sinusoidal wavecut 29 for the simultane-ous production of the corresponding sinusoidal edge of cut 16 of the wrapping blanks 27, 2T as well as by straight cuts 30 in the broadwise direction B for the production of the corresponding lateral edges 2, 4.
The width of the endless web 26 is such that two copies can be produced side by side. If the width of the endless web 26 is correspondingly in-creased, the number of side-by-side copies produced may of course rise to four, six etc. In the example of embodiment according to Fig. 2, the lateral edge 3 of the wrapping blank 27, 2T is formed by the lateral edges 31, 32 of the endless web 26.
In the case of the exemplary embodiment of Fig. 3 illustrating the cutting of the wrapping blanks 27, 2'f from the endless web 26, the sinusoidal wavecut is produced substantially parallel to the conveying direction T as is the case with the embodiment of Fig. 2. In the em-bodiment of Fig. 3, the wavecut 29 is such that there are no starting and final sections 23, 24 of reverse curvature. Rather, a misalignment V
of the respective starting and final points 20, 21 of the wavecut 29 is ' provided for compensation of the difference in level between the starting point 20 and the final point 21 of the edge of cut.
WO 96!36481 PCTlUS96/05542
7 In the embodiment of Fig. 4, the endless web 26 is provided with sinu-soidal wavecuts 29, which are placed substantially transversely to the conveying direction T for the production of wrapping blanks 27, 2T con-secutive by twos and between which cuts 30 are provided. In this re-gard, each wavecut 29 forms the edge of cut I6 of the wrapping blanks 27, 2T assigned to each other by twos. The two lateral edges 3I, 32 of the endless web 26 constitute the lateral edges 2, 4. Each straight cut 30 serves to produce the two lateral edges 3 of two subsequent wrapping blanks 2T, 27. Again, there is a misalignment V between the starting 20 and final point 21 of the edge of cut 16.
In connection with Fig. 5 it must be added that in the vicinity of the convex section I7 of the edge of cut 16, the closing flap 13 may be pro-vided for instance with a sticker 34 with which to fix the closing flap I3 to the face 5 below the concave section 19 of the removal opening 14.
This--position- is--roughly outlined by the dotted Iine in Fig. 5. When the soft pack is closed, the two side tabs 22, 25, which project from the pile 35 of tissue handkerchieves 36 in prolongation of the narrow side 7, 8, are folded inwards in the way of a gusset along the oblique folding lines 37, 38 shown by dashes in Fig. 5.
As an alternative of the sticker 34, an adhesive zone 39 roughly outlined by hatching in Fig. S may be used on the face 5 of the soft pack. This adhesive zone 39 is disposed preferably centrally in front of the concave section 19 of the edge of cut 16. It may for instance consist of a revers-ibly adhesive, pressure sensitive glue applied by dot screen printing. A
continuous Iayer of pressure sensitive glue may also be used. The exter-nal geometry of the adhesive zone 39 is advantageously suited to the contour of the substantially sickle-shaped overlap portion between the closing flap 13 and the face 5 of the soft pack, as apparent from the arcuate course of the adhesive zone 39 according to Fig. 5.
Fig. 6 illustrates further configurations of wrapping blanks designed for broadside packs or so-called "flat cases". As outlined by thick solid
In connection with Fig. 5 it must be added that in the vicinity of the convex section I7 of the edge of cut 16, the closing flap 13 may be pro-vided for instance with a sticker 34 with which to fix the closing flap I3 to the face 5 below the concave section 19 of the removal opening 14.
This--position- is--roughly outlined by the dotted Iine in Fig. 5. When the soft pack is closed, the two side tabs 22, 25, which project from the pile 35 of tissue handkerchieves 36 in prolongation of the narrow side 7, 8, are folded inwards in the way of a gusset along the oblique folding lines 37, 38 shown by dashes in Fig. 5.
As an alternative of the sticker 34, an adhesive zone 39 roughly outlined by hatching in Fig. S may be used on the face 5 of the soft pack. This adhesive zone 39 is disposed preferably centrally in front of the concave section 19 of the edge of cut 16. It may for instance consist of a revers-ibly adhesive, pressure sensitive glue applied by dot screen printing. A
continuous Iayer of pressure sensitive glue may also be used. The exter-nal geometry of the adhesive zone 39 is advantageously suited to the contour of the substantially sickle-shaped overlap portion between the closing flap 13 and the face 5 of the soft pack, as apparent from the arcuate course of the adhesive zone 39 according to Fig. 5.
Fig. 6 illustrates further configurations of wrapping blanks designed for broadside packs or so-called "flat cases". As outlined by thick solid
8 Lines, a basic type of a wrapping blank again comprises a rectangular zone 1 defined by lateral edges 2, 3, 4 and a sinusoidal edge of cut 16 , with a convex section 19 for the production of the removal opening 14.
The folding lines necessary for the production of the face 5, the back 6, , the two lateral narrow sides 7, 8 and the bottom 9 are shown by short dashes.
As seen in Fig. 6, again two wrapping blanks at a time can be produced head by head and free from waste by a transverse wavecut 29 from an 1o endless web 26 - as explained above.
As roughly outlined by lines of long dashes in Fig. 6, an alternative configuration of the wrapping blank may ~be realized, in which the later-al edge 3 of the wrapping blank opposite to the edge of cut 16 takes a course that is stepped in the way of two trapezoids 40, 41 disposed in opposite directions. In this case, the course of the lateral edge 3' thus produced is point symmetric relative to the point of intersection S' formed by the lateral edge 3' intersecting the central line M of the wrapping blank.
Fig. 6 illustrates another alternative of the shaping of the wrapping blank. This is the area roughly outlined by wide hatching. This shape is produced in that the area defined by solid lines and lines of long dashes is cut up along the central line M and in that the right part - referred to Fig. 6 - of the wrapping blank is attached, rotated by 180°. Figura-tively speaking, the two parts amalgamate in the vicinity of the abutting sections of the lateral edge 3. As a result, the convex section 17 of the edge of cut 16 defining the closing flap I3 on the one hand and the con-cave section 19 of the edge of cut 16 defining the removal opening on the other hand are disposed on two opposite sides of the wrapping blank, which are connected with each other by the straight lateral edges 2, 4.
In this embodiment, too, there is the possibility to produce wrapping blanks lined up in series from an endless web free from waste.
The folding lines necessary for the production of the face 5, the back 6, , the two lateral narrow sides 7, 8 and the bottom 9 are shown by short dashes.
As seen in Fig. 6, again two wrapping blanks at a time can be produced head by head and free from waste by a transverse wavecut 29 from an 1o endless web 26 - as explained above.

Figura-tively speaking, the two parts amalgamate in the vicinity of the abutting sections of the lateral edge 3. As a result, the convex section 17 of the edge of cut 16 defining the closing flap I3 on the one hand and the con-cave section 19 of the edge of cut 16 defining the removal opening on the other hand are disposed on two opposite sides of the wrapping blank, which are connected with each other by the straight lateral edges 2, 4.
In this embodiment, too, there is the possibility to produce wrapping blanks lined up in series from an endless web free from waste.
