Embodiments for Carrying Out the Invention

[0017] Embodiments of the paper material according to the present invention and paper articles using the same will be described based on the drawings. Note that the present invention is not limited only to the following embodiments described based on the drawings, and various technical matters described in each embodiment can be appropriately combined or replaced as needed.

[0018] [First Embodiment] A first embodiment of the paper material and paper articles utilizing the same according to the present invention will be described with reference to Figures 1 to 6.

[0019] As shown in Figures 1 and 2, this embodiment is a package 110, which is a paper container that is a vertically elongated rectangular parallelepiped paper article for housing a stick-shaped confectionery, and the paper material 100 that constitutes it. As shown in Figure 1, the paper material 100 has a pair of rectangular fronts 111 and backs 112, rectangular sides 113 and 114 provided in pairs on one side (right in Figure 1) and the other side (left in Figure 1) of the front 111, and rectangular tops 115 and bottoms 116 provided in pairs on the upper and lower sides of the front 111.

[0020] The paper material 100 has one side of its back surface 112 (right side in Figure 1) connected to the side surface 114 of the other side of its front surface 111 (left side in Figure 1). The paper material 100 has adhesive surfaces 117 on the other side of its back surface 112 (left side in Figure 1) and on its top and bottom edges. The paper material 100 has flaps 118 on the top and bottom edges of its sides 113 and 114.

[0021] Furthermore, fold lines 102 are provided between each surface 111 to 116, between the back surface 112 and the adhesive side surface 117, and between the sides 113, 114 and the flap 118. Near the top of the front surface 111, there is an opening zipper 120 with a periphery formed by a cut line 121 and a fold line 122 formed inside the cut line 121. The cut line 121 of the zipper 120 has multiple cuts 121a formed intermittently, so that connecting parts 121b are formed between adjacent cuts 121a.

[0022] Near the top of sides 113 and 114, cut lines 101 are formed, which serve as a slit connecting the cut line 121 of the zipper 120 on the front 111 to the back 112. On the glued edge 117 of the other side (left in Figure 1) of the back 112, a cut line 101 is formed that overlaps with the cut line 101 of side 113 when it overlaps with one side 113 of the front 111 (right in Figure 1). Near the top of the back 112, a fold line 102 is formed, which serves as a fold connecting the cut line 101 of side 114 to the cut line 101 of the glued edge 117.

[0023] The zipper 120 is formed so that, after being cut out, it becomes a design (a puppy in this embodiment) that can be used for paper crafting (see Figures 5 and 6). That is, as shown in Figure 3, the zipper 120 is provided with cut lines 121 that are cut out to form the outline of the design, and also with fold lines 122 that are folded into mountain folds and valley folds to make the design three-dimensional.

[0024] Furthermore, the zipper 120 has multiple (two in this embodiment) notches 121 provided in a direction O perpendicular to the cutting direction D on a plane along the cutting direction D. In the zipper 120, the connecting portions 121b of the multiple (two in this embodiment) notches 121 are formed offset so that they do not overlap at the same position in the aforementioned perpendicular direction O.

[0025] In the paper material 100 according to this embodiment, by folding each fold line 102 to form a box shape and adhering the side surface 113, top surface 115, and bottom surface 116 to the corresponding adhesive surface 117, a rectangular package 110 that is long in the vertical direction can be assembled and formed as shown in Figure 2.

[0026] In this case, the zipper 120 is formed such that the connecting portion 121b of the two notches 121 do not overlap at the same position in the orthogonal direction O. This allows the load applied to the package 110 in the orthogonal direction O to be distributed and the resistance to be increased. As a result, the decrease in the rigidity of the package 110 can be significantly suppressed.

[0027] To open the package 110, pinch one end of the zipper 120 with your hand and pull along the cutting direction D, which is the longitudinal direction of the zipper 120, and the zipper 120 can be cut along the cut line 121 (see Figure 5).

[0028] In this case, since the connecting portion 121b of the two notches 121 of the zipper 120 is formed offset so that they do not overlap at the same position in the orthogonal direction O, the connecting portion 121b of the two notches 121 can be cut sequentially at different timings without being cut simultaneously. As a result, the force required to cut the zipper 120 can be greatly reduced, making it easy for even children with little strength to open.

[0029] Next, by cutting the notches 101 on the sides 113, 114 and the adhesive side 117 and folding along the fold lines 102 on the back 112, the package 110 can be easily opened (see Figure 4), and the stick-shaped confectionery or other items can be easily removed from inside.

[0030] The zipper 120, which has been opened and cut off from the package 110 in this way, can be folded along the fold line 122 to assemble the three-dimensional puppy 120A, as shown in Figure 6.

[0031] Therefore, according to the paper material 100 and the package 110 using it according to this embodiment, the zipper 120 after cutting can be effectively reused as a paper craft without being discarded.

[0032] Furthermore, the connecting portion 121b of the two notches 121 of the zipper 120 is formed offset so that they do not overlap in the same position in the orthogonal direction O. Therefore, the load applied to the package 110 in the orthogonal direction O can be distributed and the resistance can be increased, and the decrease in rigidity of the package 110 can be greatly suppressed. Moreover, since the connecting portion 121b of the two notches 121 can be cut sequentially at different timings rather than simultaneously, the force required to cut the zipper 120 can be greatly reduced, making it easy for even children with little strength to open.

[0033] [Second Embodiment] A second embodiment of the paper material and paper articles utilizing the same according to the present invention will be described with reference to Figures 7 to 12. However, for parts that are the same as those described in the previously described embodiment, the same reference numerals used in the previously described embodiment will be used, and any explanations that overlap with the previously described embodiment will be omitted.

[0034] As shown in Figures 7 and 8, this embodiment is a package 210, which is a paper container in the shape of a rectangular parallelepiped close to a cube, for containing granular confectionery, and the paper material 200 that constitutes it. As shown in Figure 7, the paper material 200 has a pair of roughly square fronts 211 and backs 212, rectangular sides 213 and 214 provided in pairs on one side (right in Figure 7) and the other side (left in Figure 7) of the front 211, and rectangular tops 215 and bottoms 216 provided in pairs on the upper and lower sides of the front 211.

[0035] The paper material 200 has one side of its back surface 212 (right side in Figure 7) connected to the side surface 214 of the other side of its front surface 211 (left side in Figure 7). The paper material 200 has adhesive surfaces 217 on the other side (left side in Figure 7) and bottom of the back surface 212, and a lid surface 219 on the top of the back surface 212. The paper material 200 has flaps 218 on the top and bottom of the sides 213 and 214, respectively.

[0036] On the lid surface 219, an insertion piece 219a is provided projecting from the middle of the width direction (left-right direction in Figure 7) of the side (top side in Figure 7) opposite the side (bottom side in Figure 7) that connects to the back surface 212 (bottom side in Figure 7), forming a coplanar plane. On the other hand, on the top surface 215, a slit 215a is formed in the middle of the width direction (left-right direction in Figure 7) near the side (bottom side in Figure 7) that connects to the front surface 211 (bottom side in Figure 7), into which the insertion piece 219a is detachably inserted.

[0037] In the middle of the depth direction (vertical direction in Figure 7) of the top surface 215, there is an opening zipper 220 with a periphery formed by a cut line 221 that serves as a slit, and a fold line 222 that serves as a fold formed inside the area surrounded by the cut line 221. The cut line 221 of the zipper 220 has multiple cuts 221a formed intermittently, so that connecting parts 221b are formed between adjacent cuts 221a.

[0038] The zipper 220 is formed so that, after being cut out, it becomes a design (a shrimp in this embodiment) that can be used for paper crafting (see Figures 11 and 12). That is, as shown in Figure 9, the zipper 220 is provided with cut lines 221 that are cut out to form the outline of the design, and also with fold lines 222 that are folded into mountain folds and valley folds to make the design three-dimensional.

[0039] Furthermore, the zipper 220 has multiple notches 221 (in this embodiment, mostly two, and in some cases four) in a direction O perpendicular to the cutting direction D on a plane along the cutting direction D, and the cuts 221a of the notches 221 are curved in an arc (streamlined shape) along the cutting direction D.

[0040] Furthermore, the zipper 220 is formed such that the end ed located downstream of the cutting direction D (right side in Figure 9) and the end eu located upstream of the cutting direction D (left side in Figure 9) of the connecting portion 221b of the cut line 221 do not overlap in the same position along the cutting direction D.

[0041] In the paper material 200 according to this embodiment, each fold line 102 is folded to form a box shape, and the side surface 213 and bottom surface 216 are bonded to the corresponding adhesive surface 217, while the side of the top surface 215 opposite the side connected to the front surface 211 (bottom side in Figure 7) (top side in Figure 7) is bonded to the back surface 212 of the lid surface 219. As a result, a package 210 in the shape of a rectangular parallelepiped close to a cube can be assembled and formed, as shown in Figure 8.

[0042] To open the package 210, pinch one end of the zipper 220 with your hand and pull along the cutting direction D, which is the longitudinal direction of the zipper 220, and the zipper 220 can be cut along the cut line 221 (see Figure 11).

[0043] Next, by opening the top surface 215, the lid surface 219, and the sides 213 and 214, the package 210 can be easily opened (see Figure 10), and the granular confectionery or other items inside can be easily removed. Furthermore, after closing the sides 213 and 214, the package 210 can be easily resealed by closing the top surface 215 and inserting the insertion piece 219a of the lid surface 219 into the slit 215a of the top surface 215.

[0044] In this way, after the package 210 is opened and the zipper 220 is cut off, the three-dimensional shrimp 220A can be assembled as shown in Figure 12 by folding it in a mountain or valley fold along the fold line 222, as in the embodiment described above.

[0045] Therefore, according to the paper material 200 and the package 210 using it according to this embodiment, the zipper 220 after cutting can be effectively reused as a paper craft without being discarded, just as in the previously described embodiment.

[0046] Furthermore, the cut line 221a of the zipper 220 is curved in an arc (streamlined shape) along the cutting direction D, and the downstream end ed and the upstream end eu of the connecting portion 221b of the cut line 221 are offset so as not to overlap in the same position along the cutting direction D. This allows for an emphasis on three-dimensionality when assembled, thereby enhancing the design.

[0047] Furthermore, at least a portion of the connecting portion 221b of the cut line 221 of the zipper 220 is formed such that the downstream end ed is located inward in the perpendicular direction O than the upstream end eu. This prevents the zipper 220 from breaking midway when being cut, even if it is long in the cutting direction D, thereby improving the usability of the zipper 220 as a paper craft.

[0048] [Other embodiments] In the embodiments described above, we explained the case of paper materials 100, 200 having zippers 120, 220 with a design that can be cut out and used for paper crafting, extending along their entire length, and packages 110, 210 that utilize these materials, but the present invention is not limited to these.

[0049] As another embodiment, for example, it is also possible to have a paper material having a zipper on which a design that can be cut out and used as a paper craft is provided along at least a portion of its total length, and a paper article that uses the same. However, as in the embodiment described above, a paper material having zippers 120, 220 on which a design that can be cut out and used as a paper craft is provided along its entire length, and a paper article that uses the same, is highly preferable because the zipper can be used to its fullest potential.

[0050] Furthermore, while the embodiments described above describe paper materials 100, 200 and packages 110, 210 that utilize the same, having zippers 120, 220 with designs that allow for the three-dimensional molding of a puppy 120A and a shrimp 220A, the present invention is not limited thereto. As other embodiments, for example, as shown in Figures 13 and 14, it is also possible to have paper materials and paper articles that utilize the same, having a zipper 320 with a design that allows for the three-dimensional molding of a dog 320A, or as shown in Figures 15 and 16, having a zipper 420 with a design that allows for the three-dimensional molding of a giraffe 420A.

[0051] Furthermore, while the embodiments described above described the case of box-shaped packages 110, 210 and paper materials 100, 200 that contain stick-shaped or granular confectionery, the present invention is not limited to these. As other embodiments, for example, paper containers with zippers for opening, such as corrugated boxes for delivering pizzas, or cardboard envelopes for delivering documents, and the paper materials that constitute them, as well as paper materials with zippers formed by perforations and various paper articles that utilize them, the same effects and advantages as in the embodiments described above can be obtained.

[0052] For example, as shown in Figures 17 and 18, it is also possible to make a book 510, such as a booklet, which is a paper article that is bound by binding together a bag 500A made of paper material 500 on which a zipper 220 is formed.

[0053] Specifically, as shown in Figure 17, perforations 501a and 501b are formed along the width direction (left-right direction in Figure 17) on the top (upper side in Figure 17) and bottom (lower side in Figure 17) of the paper material 500, respectively. A zipper 220 is formed in the central part of the paper material 500 in the width direction (left-right direction in Figure 17) to connect the perforations 501a and 501b.

[0054] In the paper material 500 according to this embodiment, the zipper 220 is folded along the fold line 222 in the center, and glue is applied between the top (upper end in Figure 17) and the cut line 501a, and between the bottom (lower end in Figure 17) and the cut line 501b. This creates a saddle-stitched binding 500A, and by binding it together with printed sheets 530 so that the open sides are bound, a booklet or the like is formed, as shown in Figure 18, as a paper article having saddle-stitched pages.

[0055] In this embodiment of the book 510, the book 500A can be opened by cutting along the notches 501a and 501b and cutting the zipper 220. Then, the cut zipper 220 can be assembled by mountain folding or valley folding along the fold line 222, as in the embodiment described above.

[0056] Furthermore, as shown in Figure 19, for example, the flyer 610 is made of paper material 600 with a zipper 220 formed on it.

[0057] Specifically, a zipper 220 is formed on the paper material 600, closer to the bottom (in Figure 19, towards the bottom) than the middle in the vertical direction (in Figure 19, the up and down direction), connecting both ends in the width direction (in Figure 19, the left and right direction). Between the bottom (in Figure 19, the bottom edge) of the paper material 600 and the zipper 220, multiple cut lines 601a and 601b are formed in a grid pattern. The areas enclosed by the cut lines 601a, 601b and the zipper 220 are each coupon tickets 610a.

[0058] In the flyer 610, which is a paper article according to this embodiment, the coupon 610a can be used by cutting out the perforations 601a, 601b and the zipper 220. Then, the three-dimensional shrimp 220A can be assembled by folding the cut-out zipper 220 along the fold line 222, in the same manner as in the previously described embodiment.

[0059] Furthermore, as shown in Figures 20 and 21, for example, a tabletop calendar 710 can be made using a stand 700A made of paper material 700 with a zipper 120 formed on it.

[0060] Specifically, as shown in Figure 20, a fold line 702 is formed in the middle of the paper material 700 in the vertical direction (up and down direction in Figure 20) extending in the width direction (left and right direction in Figure 20), and three of these fold lines 702 are formed in the vertical direction (up and down direction in Figure 20).

[0061] Multiple holes 703a and 703b are formed on the top (upper side in Figure 20) and bottom (lower side in Figure 20) of the paper material 700, respectively, along the width direction (left-right direction in Figure 20). A zipper 120 is formed between the bottom (lower side in Figure 20) of the paper material 700 and the fold line 702, connecting the two ends in the width direction (left-right direction in Figure 20).

[0062] In the paper material 700 according to this embodiment, a stand 700A is formed by folding the fold line 702 so that the holes 703a and 703b face each other (see Figure 21). Then, multiple sheets of paper 730 are prepared, each having holes 731 corresponding to the holes 703a and 703b and on which the date is written. By passing a ring 740 through the holes 703a and 703b of the stand 700A and the holes 731 of the sheets of paper 730 and binding them together, a tabletop calendar 710, which is a paper item, is formed.

[0063] In the desktop calendar 710 according to this embodiment, when the calendar is no longer needed, the zipper 120 can be cut off from the stand 700A, and the three-dimensional dog 120A can be assembled by folding the zipper 120 along the fold line 122 in a mountain or valley fold, as in the embodiment described above. [Industrial applicability]

[0064] The paper material and paper articles utilizing the same according to the present invention can be effectively used in various industries because the zipper after tearing can be utilized. [Explanation of symbols]
