  However, since the box described in Patent Document 1 needs to cut out a relatively complicated shape such as a plurality of tongue pieces and lid pieces from the box-shaped state, it requires not only complicated work and a long time. The box itself may be damaged by the cutting operation.

  In view of the above-described points, an object of the present invention is to provide a box that can be closed again by reducing the capacity and the external shape according to the reduction of contents by a simple operation.

  In order to achieve such an object, the present invention provides a box having a cylindrical body and a pair of closing surfaces for closing both ends of the body, except for a part of the body. An excisable portion that enables excision of a predetermined band-shaped region extending in the circumferential direction of the portion and a part of the trunk portion, and the trunk portion is divided into two parts by excising the excisable portion. A connecting portion that maintains a connection state between the two divided body portions when the one divided body portion and the second divided body portion are formed, and the connecting portion is located at a boundary with the first divided body portion. The first fold line formed along the boundary between the first fold line and the second fold line formed between the first fold line and the second fold line. And a third fold line that folds the connecting part into a superposed state when the body parts are moved in the direction of approaching each other. To.

  In the case of the box of the present invention, when the capacity and the external shape are reduced in accordance with the decrease in the contents, first, the excisable part is excised and the trunk part is divided into two parts. Thereby, although a 1st division | segmentation trunk | drum and a 2nd division | segmentation trunk | drum are formed, the connection state of both division | segmentation trunk | drums is maintained by the connection part.

  Next, when the opening ends facing each other in both divided body parts are moved in the direction close to each other, for example, a mountain fold is formed via the third fold line (projecting outside the body part), and the connecting part is overlapped. It becomes a state.

  Then, the opening end portions of the two divided body portions facing each other are overlapped (for example, the opening end portion of the first divided body portion is inserted inside the opening end portion of the second divided body portion), and the capacity and appearance A box with a small shape is in a closed state.

  Further, in the present invention, the connecting portion is freed from the boundary with the first divided body portion as a base end, and the engaging portion is in a folded and overlapped state through the third fold line. It is preferable to provide a locking hole for locking the piece.

  According to this, the engagement piece can be engaged with the engagement hole to maintain the overlapping state of the connecting portion, and both end edges where the first divided body portion and the second divided body portion come into contact with each other of the connecting portion. It is possible to form a connected state using as a hinge. Accordingly, one of the divided body portions can be swung from the both closed body portions in the closed state via the hinges of the connecting portions, so that the cover can be smoothly opened.

  In the present invention, the second fold line is formed by a perforation that allows the second divided body portion and the connecting portion to be separated from each other, and the first divided body portion is the second divided body portion. Another predetermined region over the entire circumference on the end side facing the body portion and the connecting portion can be excised.

  According to this, when the contents of the box locked by the 1st division body part and the 2nd division body part further reduce, according to it, it shall be made into a closed state with a smaller volume and appearance shape. Can do. That is, first, the second divided body portion is separated from the connecting portion by breaking along the second fold line by the perforation. Next, another predetermined region of the first divided body portion is cut out together with the connecting portion. And the opening edge part of the 1st division | segmentation trunk | drum which became small in volume and external appearance shape can be made into a closed state by a 2nd division | segmentation trunk | drum.

  Moreover, in this invention, it is preferable that the said 1st division | segmentation trunk | drum is provided with the tongue piece which can swing freely in the edge part which opposes a said 2nd division | segmentation trunk | drum. According to this, the tongue piece of the 1st division body part can be inserted in the opening end part of the 2nd division body part, and the opening end part of the 1st division body part can be made into a closed state smoothly.

The second excisable part 23 is excised using another longitudinal cut line 24 provided in the first side plate 1 extending in the vertical direction as a break start part.

  With the above configuration, when the box A is formed, first, the side plates 1, 2, 3, 4 and the adhesive piece 5 are bent through the fold lines a, b, c, d, and the adhesive piece 5 is formed into the fourth. Adhere to the side plate 4 to form a square cylinder. Thereby, as shown in FIG. 1, the trunk | drum B is formed. Next, after putting the confectionery in the body part B, referring to FIG. 2, the first inner flaps 6, 6, the second inner flaps 7, 7, and the third inner flaps 8, 8 are sequentially folded inward. The outer flaps 9, 9 are bonded to the outside of the third inner flaps 8, 8. Thereby, as shown in FIG. 1, the upper and lower ends of the trunk | drum B are obstruct | occluded by the obstruction | occlusion surfaces C and C, and it will be in an unopened state.

  In order to consume the confectionery inside, when opening the box A, the first excisable portion 12 is excised as shown in FIG. 3A. Thereby, the trunk | drum B is divided | segmented into 1st division | segmentation trunk | drum Ba and 2nd division | segmentation trunk | drum which is divided | segmented into 1st division | segmentation trunk | drum Bb which functions as a 1st division | segmentation trunk | drum Ba on lower side and a lid | cover on the upper side. It remains in a state where Bb is connected. Further, by cutting off the first excisable portion 12, semi-circular tongue pieces 25, 25, 25 are formed at the end of the first divided body Ba facing the second divided body Bb. . Each tongue piece 25, 25, 25 can be freely moved by bending inward and outward.

  The first divided body portion Ba can be closed by the second divided body portion Bb. That is, as shown in FIG. 3B, the second split barrel Bb is brought close to the open end of the first split barrel Ba while the intermediate fold line 18 of the connecting portion 13 is folded in a mountain fold. Next, as shown in FIG. 3C, the upper and lower halves are folded and overlapped via the intermediate fold line 18 of the connecting portion 13, and the second divided body Bb is placed on the open end of the first divided body Ba. At this time, the tongue pieces 25, 25, 25 of the first divided body portion Ba are overlapped with the inner surface of the second divided body portion Bb, and a reliable closed state is formed.

  Thereafter, as shown in FIG. 4, when the locking piece 19 is released from the connecting portion 13 and pushed into the locking hole 20, the folded overlapping state of the connecting portion 13 is reliably maintained, and the second divided body portion Bb is covered with the lid. As described above, when the first divided body portion Ba is opened and closed, the base end of the connecting portion 13 functions as a hinge so that a smooth opening and closing operation can be performed.

  Since the connecting portion 13 can be separated from either the first divided body portion Ba or the second divided body portion Bb by the first horizontal perforation 15 and the second horizontal perforation 16, It is also possible to close the first divided body portion Ba with the second divided body portion Bb in a state where the part is removed and the hinge is removed. In order to prevent the connecting portion 13 from being separated, the first horizontal perforation 15 and the second horizontal perforation 16 may be changed to crease lines, respectively.

Moreover, the box A of this embodiment can make the volume of the 1st division | segmentation trunk | drum Ba smaller further, when internal confectionery is consumed further. That is, as shown to FIG. 5A, 2nd division | segmentation trunk | drum Bb is cut off from the connection part 13 via the 2nd horizontal perforation 16, and the 2nd excisable part 23 of 1st division | segmentation trunk | drum Ba is excised. Thereby, the height of the 1st division body part Ba falls and volume reduction is given.
And as shown to FIG. 5B, it can be closed in the state reduced in size by covering 2nd division | segmentation trunk | drum Bb on the open end of 1st division | segmentation barrel | drum part Ba.
