Next, the deployable body 210 of the second embodiment will be described with reference to FIGS. 9 to 16. FIG. In the following, description of the same points as in the first embodiment will be omitted. In the first embodiment, when the first set of plates is rotated 180 degrees relative to the second set of plates, the respective surfaces of the two right side plates 40, 42 are in contact with each other and the two left side plates 40,42 are in contact with each other. The respective surfaces of faceplates 50 and 52 contact each other. In contrast, in this embodiment, the deployable body 210 is configured such that the back surfaces of the two right side plates are in contact with each other and the back surfaces of the two left side plates are in contact with each other.

FIG. 9 shows a plan view of the deployable body 210. FIG. Hatching of reference numeral 320 means an adhesive portion present on the back side. The deployable body 210 includes front plates 220, 222, top plates 230-238, right side plates 240, 242, left side plates 250, 252, bottom plates 260-266, and rear plates 270, 272.

A boundary 300 between the top plates 232 and 233 and a boundary 302 between the top plates 234 and 235 are substantially aligned. As shown in FIG. 10, in the deployable body 10, a first plate set including a plurality of plates 220, 230, 232, 234, 240, and 250 is arranged with the boundaries 300 and 302 as rotation axes. It is configured to be rotatable with respect to a second set of plates including plates 222,233,235,238,242,252,260-66,270,272. When the first set of plates is rotated 180 degrees with respect to the second set of plates, the situation of FIG. 11 occurs.

In the state of FIG. 11 , the back surface of right side plate 240 contacts the back surface of right side plate 242 , and the back surface of left side plate 250 contacts the back surface of left side plate 252 . Here, the deployable body 10 does not include a bonding portion for bonding the back surface of the right side plate 240 and the back surface of the right side plate 242, and the bonding portion for bonding the back surface of the left side plate 250 and the back surface of the left side plate 252. do not have departments. According to this configuration, after the packaging container 202 is formed from the unfoldable body 210, the first plate set including the right side plate 240 and the left side plate 250 can be easily separated from the packaging container 202 (FIGS. 15 and 16). reference).

In the state of FIG. 11 , the back surface of the top plate 232 contacts the back surface of the top plate 233 , and the back surface of the top plate 234 contacts the back surface of the top plate 235 . Also, the rear surface of the front plate 220 contacts the rear surface of the front plate 222 . Here, as shown in FIG. 9 , an adhesive portion 320 is provided on the rear surface of the front plate 220 . In the state of FIG. 11, the back surface of the front plate 220 and the back surface of the front plate 222 are bonded together by the bonding portion 320 . Thereby, formation of a gap in the front portion of the packaging container 202 can be suppressed. In addition, in a modified example, an adhesive portion may be provided on the back surface of the front plate 222 .

Next, each plate is folded (that is, rotated) from the state shown in FIG. 11 to form the packaging container 202 shown in FIG. Specifically, the top plates 232 and 233, the right side plates 240 and 242, and the bottom plate 264 are rotated 90 degrees to the rear side about the folding line 340, and the bottom plate 264 is rotated about the folding line 341 as the rotation axis. Rotate 90 degrees to the side. Next, the back plate 272 is rotated 90 degrees to the back side about the folding line 342, and the top plates 234, 235, the left side plates 250, 252, and the bottom plate 266 are rotated 90 degrees to the back side about the folding line 343 as the rotation axis. , and the bottom plate 266 rotates 90 degrees to the rear side with the folding line 344 as the axis of rotation. Next, the top plate 238, the bottom plate 262, and the back plate 270 are rotated 90 degrees to the back side around the folding line 345, and the bottom plate 262 is rotated 90 degrees to the back side around the folding line 346, The bottom plate 260 rotates 90 degrees to the back side with the folding line 347 as the axis of rotation.

As shown in FIG. 9, the top plate 232 has a right folding line 310 formed at a position a predetermined distance L2 away from the boundary 300 on the upper side of the paper surface, and the top plate 233 is located on the lower side of the boundary 300 on the paper surface. has a right turn line 312 formed at a position separated by a predetermined distance L2. Therefore, in the state of FIG. 12, the two right bend lines 310 and 312 are aligned substantially on a straight line. 12, the top plates 232, 233 rotate 90 degrees toward the inside of the packaging container 202 about the two right folding lines 310, 312 as rotation axes. As a result, formation of a gap between the upper surface portion and the right side surface portion of the packaging container 202 can be suppressed.

Similarly, as shown in FIG. 9, the top plate 234 has a left bend line 314 formed at a position a predetermined distance L2 above the boundary 302, and the top plate 235 extends from the boundary 302. A left turn curve 316 is formed at a position separated by a predetermined distance L2 on the lower side of the drawing. Then, the top plates 234 and 235 rotate 90 degrees toward the inside of the packaging container 2 from the state shown in FIG. As a result, formation of a gap between the upper surface portion and the left side surface portion of the packaging container 2 can be suppressed.

Next, the top plate 230 is rotated 90 degrees toward the inside of the packaging container 202 about the folding line 350, and the top plate 230 and the top plates 232, 234 are bonded to each other by a bonding portion (not shown). Also, the top plate 238 rotates 90 degrees toward the inside of the packaging container 2 around the folding line 351 as a rotation axis, and the top plate 238 and the top plates 233 and 235 are bonded to each other by bonding portions (not shown). Thereby, the packaging container 202 of FIG. 13 is completed.

In the state of FIG. 13, front plates 220 and 222 form the front portion of packaging container 2 . In particular, the back surface of the front plate 220 and the front surface of the front plate 222 are exposed to the front of the packaging container 202 . Also, top plates 230 to 238 form the top portion of the packaging container 202 . In particular, the back surface of the top plate 230 and the top surface of the top plate 238 are exposed to the top surface of the packaging container 202 .

Also, right side plates 240 and 242 form the right side portion of the packaging container 202 . In particular, the back surface of the right side plate 240 and the front surface of the right side plate 242 are exposed to the right side surface of the packaging container 202 . Here, the entire boundary 240A (see FIG. 9) of the right side plate 240 on the back side of the packaging container 202 is covered with the right side plate 242. As shown in FIG. According to this configuration, formation of a gap between the right side plate 240 and the right side plate 242 in the right side portion of the packaging container 202 can be suppressed. In a modified example, deployable body 210 may be configured such that only part of boundary 240</b>A of right side plate 240 is covered with right side plate 242 . Also, according to this embodiment, the entire surface of the right side plate 242 is exposed. For this reason, a lot of information (for example, information about contents) can be printed on the surface of the right side plate 242 . In the first embodiment (see FIG. 5), since most of the surface of the right side plate 42 is not exposed, not only the front surface of the deployable body 10 but also the back surface (for example, the back surface of the front plate 20, the back surface of the right side plate 40, etc.) may also need to print information. According to this embodiment, since the entire surface of the right side plate 242 is exposed, there is no need to print information on the rear surface of the development body 210 . However, in a modified example, information may be printed on the rear surface of the deployable body 210 .

Although not visible in FIG. 13, left side plates 250 and 252 form the left side of packaging container 202 . In particular, the back surface of the left side plate 250 and the front surface of the left side plate 252 are exposed to the left side surface of the packaging container 202 . Here, the entire boundary 250A (see FIG. 9) of the left side plate 250 on the back side of the packaging container 202 is covered with the left side plate 252. As shown in FIG. According to this configuration, formation of a gap between the left side plate 250 and the left side plate 252 in the left side portion of the packaging container 202 can be suppressed. Also, since the entire surface of the left side panel 252 is exposed, much information can be printed on the surface of the left side panel 252 .

13, the bottom plates 260 to 266 form the bottom portion of the packaging container 202, and the back plates 270 and 272 form the back portion of the packaging container 2. As shown in FIG. Next, a configuration for separating a portion of the packaging container 202 will be described in detail below.

As shown in FIG. 9, perforations 340 are formed on the top plate 232 . In other words, a perforation 340 is formed between the right side plate 240 and the right side plate 242 . In addition, perforations 342 are formed on the top plate 234 . In other words, a perforation 342 is formed between the left side plate 250 and the left side plate 252 . That is, in this embodiment, perforations 340 and 342 are formed near the rotation shafts 300 and 302 for rotating the first plate set by 180 degrees with respect to the second plate set. To this end, the first set of plates can be separated from the packaging container 202 by breaking the perforations 340 , 342 . Each perforation 340 , 342 extends obliquely from each boundary 300 , 302 toward the rear side of the packaging container 202 . Note that, in a modified example, the perforations 340 and 342 may extend obliquely toward the front side of the packaging container 202 or may extend in a direction perpendicular to the boundaries 300 and 302 . Note that in this embodiment, the boundaries 300 and 302 are not perforations. However, in the modified example, instead of providing the perforations 340 and 342 as in the first embodiment, the boundaries 300 and 302 may be perforations.

Further, as shown in FIG. 9, perforations 322 are formed on the front plate 220 . The perforations 322 are located near the bonding portion 320 after the front plate 220 and the front plate 222 are bonded together. Specifically, perforation 322 is formed to surround adhesive portion 320 . The length of the perforations 322 in the left-right direction is shorter than the length of the packaging container 202 in the left-right direction, that is, the length of the front plate 220 in the left-right direction. According to this configuration, compared to a configuration in which perforations are formed over the entire lateral direction of the packaging container 202, it is possible to easily break the periphery of the adhesive portion 320 along the perforations 322 (FIGS. 15 and 15). See Figure 16). In addition, perforations 330 are formed on the top plate 230 .

First, when the vicinity of the perforations 330 of the top plate 230 is pressed, part of the top plate 230 is broken along the perforations 330, and as shown in FIG. is formed. Thereafter, as shown in FIG. 15, a finger is inserted into opening 360 to wrap the first set of plates, including front plate 220, top plates 230, 232, 234, right side plate 240, and left side plate 250. A force is applied from the upper surface of the container 202 toward the front. In this case, each of the perforations 322 , 340 , 342 breaks and separates the first plate set from the packaging container 202 . Thereby, as shown in FIG. 16, the packaging container 202A after separation is completed.

According to the deployable body 210 of this embodiment, the first set of plates including the plates 220, 230, 232, 234, 240, and 250 is configured to include the plates 222, 233, 235, 238, 242, 252, Packaging container 202 is formed by rotating 180 degrees with respect to a second set of plates comprising 260-266,270,272. For this reason, the packaging container 202 can be molded from one unfolded body 210 . Also, the first set of plates can be separated from the packaging container 202 to form an opening in the packaging container 202 . For this reason, it is not necessary to provide a cut line across the entire horizontal area of the packaging container 202 . Therefore, the packaging container 202A looks good after the first plate set is separated.

As shown in FIG. 17, perforations 502 are formed on the back plate 470 . In the state of FIG. 19, when a force is applied near the perforations 502, the perforations 502 are broken, and as a result, the back plate 470 is partly separated. This allows the first set of plates to be separated from the packaging container 402 while the insertion portion 510 is inserted into the hole portion 500 . Since the insertion portion 510 need not be separated from the hole 500, the first set of plates can be easily separated from the packaging container 402. FIG. Note that in a modified example, the perforations 502 may not be provided.
