  A through hole 90 that is elongated in the connecting direction and opens at both ends in an arc shape is provided at a position slightly closer to the outer top cover piece 46 of the side surface 18. It is continuous. A folding line 92, which is a notch for assisting folding at the time of opening, is provided in parallel with the connecting direction at a position slightly closer to the inner upper cover piece 50 of the side surface 22. The side surface 20 is provided with a first break line 94 at a position connecting one end of the folding line 92 and one end of the through-hole 90, and the glued piece 24 extends the other end of the folding line 92. One break line 96 is provided, and a first break line 98 is provided on the side surface 16 at a position connecting the other end of the through hole 90 and the center of the second break line 44 of the knob 42. Therefore, in the assembled state, the folding line 92, the first breaking lines 94, 96, 98, and the through holes 90 are continuous, and make a round of the side wall of the cylindrical body formed by the side surfaces 16, 18, 20, and 22.

  As described above, the box-forming piece 12 has the transparent resin film 14 attached to the entire front surface, and the through holes 90 are closed with the resin film. The resin film 14 may be of a size that covers at least the range including the through-hole 90 and the knob piece 42. Here, in order to improve the dirt resistance, water resistance, etc. of the entire packaging box 10, the box is formed. The entire surface of the piece 12 is covered. The resin film 14 is delimited by a half-cut line 100 that surrounds the peripheral portion of the through-hole 90 and the peripheral portion 90a that includes the knob piece 42 and the first break lines 94 and 98, and the inside of the half-cut line 100 is unsealed. Part 102. The half-cut line 100 is obtained by cutting the resin film 14 and cutting the half of the thickness without cutting the box forming piece 12.

  The box-forming piece 12 to which the resin film 14 is attached can be manufactured, for example, by the method shown in FIG. First, as shown in FIG. 3A, an ink layer 106 representing a product name, a company name, a design image, and the like is printed at a predetermined position of a paper blank sheet 104. Next, as shown in FIG. 3B, the through hole 90 is punched out using the punching blade 108. At the same time, a second break line 44, a notch 50, a sewing machine line 54, a folding line 92, and first break lines 94, 96, 98 (not shown) are also formed.

  Next, as shown in FIG. 3C, an adhesive is applied to the side of the blank sheet 104 where the ink layer 106 is formed to form an adhesive layer 110, and a large resin film 14 is attached to the surface. And glue. The base material of the resin film 14 is preferably, for example, polypropylene (PP) resin or polyethylene terephthalate (PET) resin, and may be colored as long as it is transparent enough to visually recognize the contents in the packaging box 10. Good. Also, the adhesive layer 110 is preferably close to transparency so that the ink layer 106 can be seen through.

  And as shown in FIG.3 (d), the half cutting line 100 surrounding the peripheral part 90a of the through-hole 90 is formed using the cutting blade 112. As shown in FIG. The half cut line 100 cuts the resin film 14 and reaches a depth halfway through the blank sheet 104. At the same time, the outer shape of the box-forming piece 12 is punched out using the punching blade 114. If such a manufacturing method is used, the box-forming piece 12 can be easily mass-produced.

  Next, a method for assembling the box forming piece 12 to which the resin film 14 is attached will be described. Here, FIG. 2 is a view of the box-forming piece 12 as viewed from the front side. Hereinafter, the folding method in which the front-side surface of the box-forming piece 12 is convex is folded forward, and the back side is convex. This folding method is called reverse folding.

  First, the crease lines 40, 58, 72, and 82 are normally folded, and the crease line 64 of the glued piece 62 and the crease line 88 of the glued piece 86 are respectively folded backward. Then, paste is applied to the back side surface of the glued piece 62 and the crease line 26 is normally folded. Thereby, the back surface of the glued piece 62 is glued to the front surface of the flap 38. Similarly, glue is applied to the back side surface of the glued piece 86 and the crease line 30 is normally folded. Thereby, the back surface of the glued piece 86 is glued to the front surface of the flap 70. Next, glue is applied to the front side surface of the glued piece 24, and the back side surface of the side surface 14 is glued in accordance with the front side surface of the glued piece 24. And it is shipped from the manufacturing factory of the box formation piece 12 in this folded state.

  Next, in a factory or the like for containing and packaging items such as merchandise, the crease lines 26, 28, 30, and 32 are normally folded at 90 degrees to form a rectangular cylindrical body. Then, the first bottom cover piece 56 is raised together with the flap 38 from the side face 18 and is normally folded at right angles at the crease line 58, and at the same time, the second bottom cover piece 80 is raised together with the flap 70 from the side face 22 and is perpendicular at the crease line 82. It is folded forward. Further, the insertion piece 60 of the first bottom cover piece 60 is inserted into the back side of the end portion 80 a of the second bottom cover piece 80, and the insertion piece 84 of the second bottom cover piece 80 is the end portion of the first bottom cover piece 56. It is inserted in the back side of 56a, and it mutually latches reliably. In this manner, a bottom lid is formed which is an end surface member that closes one end of the cylindrical body formed of the side surfaces 16, 18, 20, and 22. Further, the knob piece 42 protrudes over the extension of the side surface 16 beyond the crease line 32 of the side surface 22.

  In this state, after accommodating the contents in the cylindrical body, the flaps 34 and 66 are normally folded at 90 ° by the crease lines 36 and 68, and the inner upper lid piece 76 is normally folded at 90 ° by the crease line 78. Then, after the insertion piece 52 is normally folded at 90 ° with the sewing machine line 54, the outer upper lid piece 46 is oriented at 90 ° with the crease line 48 while inserting the insertion piece 52 into the notch 50 at the position of the crease line 78. Fold it. In this manner, an upper lid that is an end surface member that closes one end of the cylindrical body formed of the side surfaces 16, 18, 20, and 22 is formed.

  The packaging box 10 assembled in this way is in the state shown in FIGS. 1A and 1B, and the contents contained therein can be viewed through the transparent resin film 14 that closes the through holes 90.

  Next, the usage method of the packaging box 10 is demonstrated. When the consumer wants to open the through hole 90 closed with the resin film 14 so as to touch the contents contained therein, the knob 42 is picked together with the end of the film opening portion 102, and the second breaking line 44 is broken. Then, the tab 42 is separated from the side surface 16, and the film opening portion 102 is peeled off from the peripheral portion 90a as shown in FIG. As shown in FIG. 3E, the peripheral portion 90a from which the film opening portion 102 has been peeled is peeled off integrally with the adhesive layer 110 of the film opening portion 102, leaving only the lower layer portion. Moreover, since the resin film 14 part except the film opening part 102 is isolate | separated from the film opening part 102 by the half cut line 100, even if it peels off the film opening part 102, it will not be influenced. When the film opening portion 102 is peeled off to the end, the through hole 90 is opened and the first break lines 94, 96, 98 are also exposed.

  Furthermore, when opening the packaging box 10 and taking out the contents contained therein, as shown in FIG. 5, the first break lines 94, 96, 98 are broken to separate the cylindrical body, and the folding line 92 is formed. The upper lid side portion of the cylindrical body is tilted while being reversely folded, and the contents are taken out from the inside.

  As described above, the packaging box 10 has a structure that surrounds the entire package so as not to damage the package such as merchandise in the process of distribution in the market, and is still unopened when displayed at the storefront. You can see the contents. Further, the consumer can easily open the through hole 90 by holding the knob 42 and peeling off the film opening portion 102, and can directly see or touch the contents contained therein. Further, it is possible to store the contents in the packaging box 10 even after the consumer opens the through hole 90.

  In particular, when opening the packaging box 10, the three side surfaces 16, 18, and 20 of the cylindrical body are formed by tearing off the film opening portion 102 and breaking the exposed first break lines 84, 96, and 98. Since it can be opened separately from the top and bottom, the contents can be easily taken out.

  Next, 2nd embodiment of the packaging box of this invention is described based on FIG. The packaging box of this embodiment is obtained by changing the structure of the film opening portion 102 of the peripheral edge portion 90a of the through hole 90 in the packaging box 10 described above. Here, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the box-forming piece 116 according to this embodiment, a release agent layer 118 that restricts the adhesive strength of the adhesive 110 is provided on the peripheral edge 90 a of the through hole 90, and the film opening portion 102 is an upper surface of the release agent layer 118. It is peeled and adhered. Other configurations are the same as those of the box-forming piece 12.

  The box-forming piece 116 can be manufactured, for example, by the method shown in FIG. First, as shown in FIG. 6A, a release agent layer 118 is provided by a method such as printing so as to cover a region corresponding to the peripheral edge portion 90 a of the paper blank sheet 104. Next, as illustrated in FIG. 6B, an ink layer 106 representing a product name, a company name, a design image, or the like is printed at a position other than the peripheral edge 90 a of the blank sheet 104. The order of FIGS. 6A and 6B may be reversed. Next, as shown in FIG. 6C, the through hole 90 is punched using the punching blade 108. At the same time, a second break line 44, a notch 50, a sewing machine line 54, a folding line 92, and first break lines 94, 96, 98 (not shown) are also formed. Next, as shown in FIG. 6D, an adhesive is applied to the side of the blank sheet 104 where the ink layer 106 is formed to form an adhesive layer 110, and a large resin film 14 is attached to the surface. And glue. Then, as shown in FIG. 6 (e), a half-cut line 100 surrounding the peripheral edge portion 90 a of the through hole 90 is formed using the cutting blade 112. The half-cut line 100 cuts the resin film 14 and reaches a depth halfway through the blank sheet 104. At the same time, the outer shape of the box forming piece 116 is punched using the punching blade 114.

  The method of using the packaging box 10 constituted by the box-forming pieces 116 is the same as that of the case where the box-forming pieces 12 are used. That is, when opening the through-hole 90 closed with the resin film 14, the knob 42 is picked together with the end of the film opening portion 102, the second breaking line 44 is broken, and the knob 42 is separated from the side surface 16. In the same manner as the operation shown in FIG. 4, the film opening portion 102 is peeled off from the peripheral edge portion 90a. At this time, since the adhesive 110 peels cleanly at the interface with the release agent layer 118, the peripheral portion 90a from which the film opening portion 102 has been peeled off does not cause tearing or the like on the surface layer portion of the paper board, and FIG. As shown in f), a smooth surface release agent layer 118 appears.

  Next, a third embodiment of the packaging box according to the present invention will be described with reference to FIGS. The packaging box of this embodiment is also the same as the packaging box 10 except that the structure of the film opening portion 102 of the peripheral edge 90a of the through hole 90 is changed. Here, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  The box-forming piece 120 according to this embodiment includes an ink release agent layer 122 that represents a negative shape of a predetermined character or a pattern, and an entire peripheral portion 90 a including the ink release agent layer 122 on the peripheral portion 90 a of the through-hole 90. An ink layer 124 that covers the upper surface, and a release agent layer 126 that covers the upper surface of a region of the ink layer 124 that does not overlap with the ink release agent layer 122 and restricts the adhesive strength of the adhesive 110 are provided. The upper surface of the layer 124 and the release agent layer 126 are detachably bonded. Other configurations are the same as those of the box-forming piece 12 of the above embodiment.

  The box-forming piece 120 can be manufactured, for example, by the method shown in FIG. First, as shown in FIG. 7A, an ink release agent layer 122 representing a predetermined character or pattern is provided in a peripheral portion 90a of a paper blank sheet 104 by a method such as printing. For example, a decorative figure or a cautionary note such as “Please use as soon as possible after opening”. The ink release agent layer 122 adheres firmly to the blank sheet 104, but a release agent that is weakly bonded to the ink layer 124 is selected. Next, as shown in FIG. 7B, a product name, a company name, a design image, and the like are displayed at predetermined positions on the ink layer 124 covering the peripheral edge portion 90 a including the ink release agent layer 122 and the blank sheet 104. The ink layer 124 is printed. Next, as shown in FIG. 7C, a release agent layer that covers the upper surface of a region that does not overlap the ink release agent layer 122 of the ink layer 124 provided on the peripheral edge portion 90 a and restricts the adhesive strength of the adhesive 110. 126 is provided by a method such as printing. The release agent layer 126 has a positive shape such as a decorative figure or a cautionary note. Next, as shown in FIG. 7 (d), the through hole 90 is punched using the punching blade 108. At the same time, a second break line 44, a notch 50, a sewing machine line 54, a folding line 92, and first break lines 94, 96, 98 (not shown) are also formed. Next, as shown in FIG. 7E, an adhesive is applied to the side of the blank sheet 104 where the ink layer 124 is formed to form an adhesive layer 110, and a large resin film 14 is attached to the surface. And glue. The adhesive layer 110 is a material that adheres firmly to the blank sheet 104 and the ink layer 124 and is selected to be nearly transparent so that the ink layer 124 can be seen through. Then, as shown in FIG. 7 (f), a half-cut line 100 surrounding the peripheral edge portion 90 a of the through hole 90 is formed using the cutting blade 112. The half-cut line 100 cuts the resin film 14 and reaches a depth halfway through the blank sheet 104. At the same time, the outer shape of the box forming piece 120 is punched out using the punching blade 114.

  The method of using the packaging box 10 constituted by the box-forming pieces 120 is the same as the case where it is constituted by the box-forming pieces 12 described above. That is, when the consumer wants to open the through-hole 90 closed with the resin film 14 so as to touch the contents contained therein, the knob 42 is picked together with the end of the film opening portion 102, and the second breaking line 44. And the knob 42 is separated from the side surface 16, and the film opening portion 102 is peeled off from the peripheral portion 90a in the same manner as the operation shown in FIG. At this time, since the adhesive 110 is peeled off at the interface with the release agent layer 126 and the ink layer 124 is peeled off at the interface with the ink release agent layer 122, the peripheral portion 90a from which the film opening portion 102 has been peeled off is As shown in FIG. 7G, a portion of the ink layer 124 without the ink release agent layer 122 remains, and a predetermined pattern appears as shown in FIG.

  If the box-forming piece 120 of this embodiment is used, it is possible to improve the appearance of the peripheral edge 90a from which the film opening portion 102 has been peeled off, and to display information such as a note.

  Next, 4th embodiment of the packaging box of this invention is described based on FIG. The packaging box of this embodiment is obtained by changing the position where the through hole 90 is provided and the size thereof in order to change the method for taking out the contents in the packaging box 10. Here, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 9, the box-forming piece 128 of this embodiment replaces the through hole 90 and the peripheral portion 90 a of the box-forming piece 12 with a wide range of the side surface 18 and a part of the outer upper lid piece 46. A through hole 130 and a peripheral edge 130a are newly provided in the range. Further, the knob 42, the folding line 92, and the first breaking lines 94, 96, 98 provided on the box forming piece 12 are omitted. Other configurations are the same.

  Since the method of assembling the box forming piece 128 is the same as that of the box forming piece 12, the description thereof is omitted. The method of opening the through-hole 130 closed by the resin film 14 is almost the same, but here, in place of the omitted knob 42, a knob 102a provided at the end of the film peeling portion 102 is provided. To remove it. When the contents in the packaging box 10 are taken out, they are taken out from the through holes 130 that are opened relatively large. For example, if a large number of jasper and caramel are accommodated, one or two can be taken out by inserting a finger into the through hole 130. Further, by applying the structure of the third embodiment described above, a notice such as “Don't eat too much because it is delicious” may appear on the peripheral portion 130a of the through hole 103.

  The packaging box of the present invention is not limited to the above embodiment, and the shape and position of the half-cut line that divides the through hole and the film opening part can be freely set, and the irregular waveform or Anything, such as a wave inclined in one direction, a continuous triangle or a semicircle, is acceptable. Moreover, it is not limited to a rectangular parallelepiped or a cubic box, but may be another polygonal packaging box or an irregular three-dimensional packaging box. When providing a first breaking line that divides the cylindrical body vertically, a straight line Other waveforms may be used.
