DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, a method for manufacturing a product with a packaging box according to one embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to the following embodiment.

[0022] Fig. 1 is a diagram showing a packaging box for a product with a packaging box according to one embodiment of the present invention. (a) is a front view. (b) is a side view showing a state in which the lid surface part is open. As shown in Figs. 1(a) and (b), a packaging box 1 used for a product to be packaged in a packaging box is a hexahedral box main body 2 with one side open, and a base end edge 3a of a lid surface part 3 that closes the one side is joined to the box main body 2 in a foldable manner. In the following description, the left side of Fig. 1(b) will be referred to as the front and the right side as the rear.

[0023] Then, by folding, a first attached surface portion 4 extending from one edge 2a side to the other edge side is disposed on one edge 2a of the box body 2 (one edge of one surface that is open of the box body 2) that corresponds to the leading edge 3b of the lid surface portion 3. The lid surface portion 3 is folded, and the leading edge 3b of the lid surface portion 3 is attached to the first attached surface portion 4 so that the leading edge 3b of the lid surface portion 3 coincides with the one edge 2a of the box body 2, thereby forming the packaging box 1.

[0024] The first attached surface portion 4 extends from one edge 2a (the tip edge 3b of the lid surface portion 3) of the box body 2 to the other edge (the base edge 3a of the lid surface portion 3), and is provided with a support surface portion 5 extending rearward (the right side in FIG. 1(b)) from the side edge of the other edge, with the support surface portion 5 being horizontal from below. The support surface portion 5 extends to the back surface portion 2A of the box body 2, and the back surface portion 2A supports the first attached surface portion 4 via the support surface portion 5 so that it is parallel to the back surface portion 2A.

[0025] A second attached surface portion 6 is also disposed next to the first attached surface portion 4 on the base end edge 3a side of the cover surface portion 3. This second attached surface portion 6 is provided with support surface portions 7, 8 on both side edges that extend to the back surface portion 2A of the box body 2, and the support surface portions 7, 8 are horizontal from below. The support surface portions 7, 8 extend to the back surface portion of the box body 2, and the back surface portion supports the second attached surface portion 6 via the support surface portions 7, 8 so that it is parallel to the back surface portion.

[0026] The cover surface portion 3 is attached at its four corners to the ends of the first and second attached surface portions 4, 6 (see adhesive attachment positions P1 to P4). The opposing support surface portions 5, 7 can also be structured such that holes are drilled and contents such as containers are inserted and held in the holes. In this embodiment, the rear edges of the support surface portions 5, 7 are connected to each other by a connecting surface portion 9 that fits along the bottom surface of the box body 2, ensuring shape retention.

[0027] In this way, the attached surface portions 4, 6, the supporting surface portions 5, 7, and the connecting surface portion 9 can function as a holding frame having a size corresponding to the packaging box 1 and holding the contents. The attached surface portions 4, 6 are part of the holding frame, and are aligned parallel to one edge 2a of the box body 2.

[0028] The box body 2 also includes side parts 2Da and 2Db formed by bending the upper surface part 2B and the lower surface part 2C to both sides to form side surfaces, and a side part 2Dc formed by bending the rear surface part 2A to both sides. The side part 2Dc is disposed so as to cover a part of the side parts 2Da and 2Db.

[0029] The side parts 2Da and 2Db are sized so that the top and bottom dimensions are such that they do not touch each other and have a predetermined gap, and the left and right dimensions are such that they extend forward from the back part 2A of the box body 2 and have a predetermined gap from the front end. In addition, the side parts 2Da and 2Db are each inclined in an eight-shape from the part where the side part 2Dc covers in the direction in which the predetermined gap widens. This shape makes it easier to take out the contents with your fingers when taking out the contents, and at the same time, the strength of the part overlapping with the side part 2Dc can be ensured.

[0030] The side part 2Dc has a generally rectangular shape that extends from the upper end to the lower end of the box body 2 and extends forward from the rear part 2A of the box body 2 to cover parts of the side parts 2Da and 2Db. This configuration improves the strength of the box body 2 and the holding frame. The side part formed by these side parts 2Da, 2Db, and 2Dc allows the contents to be visually confirmed, while stabilizing the box body 2 and the holding frame.

[0031] (Defective judgment system) Here, in the above-mentioned box body 2, if the position of the lid surface part 3 is misaligned when it is attached to the first attached surface part 4 (box body 2), it will look bad, so a system to be described below is used to judge whether it is defectively attached. Note that if there is a defect in the attachment of the lid surface part 3 to the second attached part 6, this will cause a defect in the attachment of the lid surface part 3 to the first attached surface part 4 (box body 2), so it is considered that it is sufficient to judge whether there is a defect in the attachment only for the attachment of the lid surface part 3 to the first attached surface part 4 (box body 2).

[0032] 2(a) and (b) show an example of a gluing defect judgment system used to judge gluing defects in the lid surface portion 3 of a packaging box 1. In this system, packaging boxes 1 in which products are packed are transported in order on a transport conveyor 11 (transport path) while maintaining a constant interval.

[0033] An imaging means 12 is disposed midway above the transport conveyor 11 to capture an image of the bonding portion between the attached surface portion 4 and the tip portion of the lid surface portion 3. A portion where the packaging box 1 is bonded is disposed upstream of the portion where the imaging means 12 is disposed.

[0034] A passage detection means 13 is provided upstream of the portion where the photographing means 12 is provided, which detects the passage of the packaging box 1 relative to the transport conveyor 11. The passage detection means 13 includes an illumination means 13A provided on one side of the transport conveyor, and a light receiving means 13B provided opposite the illumination means 13A on the other side of the transport conveyor 11. When the packaging box 1 passes, it blocks the light from the illumination means 13A, and the passage is detected by the blocking.

[0035] Since the distance between the position where the passage detection means 13 is provided and the photographing position by the photographing means 12 is known, it is possible to calculate how long it will take for the packaging box 1 to pass the area where the photographing means 12 is provided after passing the area where the passage detection means 13 is provided, taking into consideration the transport speed of the transport conveyor 11. Therefore, the timing of photographing by the photographing means 12 is determined based on the detected passing time of the packaging box 1. The amount of deviation can be calculated by using a well-known image processing method for the image (image of the pasted part) photographed by the photographing means 12.

[0036] That is, the amount of misalignment between one edge 2a of the box body 2 and the tip edge 3b of the lid surface portion 3 in the direction perpendicular to one edge 2a of the box body 2 is detected, and if the amount of misalignment exceeds a set amount (for example, 5 mm), it is determined that the bonding is defective. If the bonding is defective, the operator is notified of this fact using a display, a buzzer, etc.

[0037] In this case, the amount of misalignment is detected at two locations near both ends of the bonded portion (near adhesive bonding positions P2 and P4 in Figure 1(a)), and if the set amount is exceeded simultaneously near both ends, it is determined that the bonding is defective.

[0038] As described above, the preferred embodiment of the present invention has been described with reference to the drawings, but various additions, modifications, or deletions are possible within the scope of the present invention. For example, the present invention may be applied to a wide packaging box 1A having a shape as shown in Fig. 3(a)(b). In this case, the packaging box 1A is configured such that the base end edge 23a of the lid surface portion 23 is foldably connected to the hexahedral box body 22, and the lid surface portion 23 is folded and the tip edge portion of the lid surface portion 23 is attached to the first attachment surface portion 24 so that the tip edge 23b of the lid surface portion 23 coincides with one edge 22a of the box body 22.

[0039] The first attached surface portion 24 is supported by a support surface portion 25 extending rearward (to the right in FIG. 3(b)) so as to be parallel to the rear surface portion. A second attached surface portion 26 is also arranged next to the base end edge 23a of the lid surface portion 23. This second attached surface portion 26 is also supported by support portions 27, 28 extending to the rear surface portion of the box body 2 so as to be parallel to the rear surface portion.

[0040] The cover surface portion 23 is attached at its four corners to the ends of the first and second attached surface portions 24, 26 (see adhesive attachment positions P11 to P14). For example, holes may be drilled in the opposing support surface portions 15, 17 to hold contents of a container or the like larger than those in the above-described embodiment. The rear edges of the support surface portions 25, 27 are connected to each other by a connecting surface portion 29. [Explanation of symbols]
