It is a figure which shows one process of forming a box from the blank sheet. It is a figure which shows one process of forming a box from the blank sheet. It is a figure which shows the intermediate body of the box.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a box 1 of the present embodiment. The box 1 is made of a bendable material such as paper. The box 1 is formed in a substantially hexagonal columnar shape having a regular hexagonal top surface (first top surface) 31 and a ground surface (first ground surface) 32 and six substantially rectangular side surfaces.

FIG. 2 is a cross-sectional view taken along the line II of FIG. The side surfaces of the box body 1 are sequentially arranged via a folding line, and the first surface 11, the second surface 12, the third surface 13, the fourth surface 14, and the fifth surface 15 constituting the hexagonal columnar outer surface. And the sixth surface 16, and the first auxiliary surface 21 and the second auxiliary surface 22 that are connected to the sixth surface and connect the first surface 11 and the sixth surface 16.
In the first surface 11 and the sixth surface 16, the first auxiliary surface 21 enters the inside of the box 1, and the second auxiliary surface 22 that is folded outward with respect to the first auxiliary surface 21 is the first surface 11. The inner surface is connected by bonding or the like. Thereby, the side surface of the box 1 is connected so that a sealed state can be maintained when the box 1 is completed.

When the user puts a hand or finger on the first surface 11 and the first auxiliary surface 21 and applies a force to separate the two surfaces, the box 1 is opened from the side as shown in FIG. The
As shown in FIG. 3, there is a hexagonal second ground 42 inside the ground 32, the second ground 42, the fourth surface 14, the fifth surface 15, the sixth surface 16, and the first auxiliary surface. 21 is connected. Similarly, inside the top surface 31 is a hexagonal second top surface 41, and the second top surface 41, the fourth surface 14, the fifth surface 15, the sixth surface 16, and the first auxiliary surface 21. And are connected.
On the other hand, the top surface 31 and the ground surface 32 are connected to the first surface 11, the second surface 12, and the third surface 13.

With the structure as described above, the box body 1 includes the first top surface 41, the second ground surface 42, the fourth surface 14, the fifth surface 15, the sixth surface 16, and the first auxiliary surface 21. 51 and a second divided body 52 including a top surface 31, a ground surface 32, a first surface 11, a second surface 12, and a third surface 13. When the user bends the first divided body 51 and the second divided body 52 outward along the folding line between the third surface 13 and the fourth surface 14, the box 1 is opened.

When the box 1 is opened, the first auxiliary surface 21 and the second auxiliary surface 22 are cut along a perforation (cutting auxiliary line) 61 provided therebetween. A part of the folded second auxiliary surface remains as a flap 62 on the first auxiliary surface 21. On the other hand, a part of the first auxiliary surface 21 remains on the second auxiliary surface 22 side, and a locked portion 63 is formed on the first auxiliary surface 21.

When the box body 1 is opened once and then bent so that the first divided body 51 and the second divided body 52 are brought close to each other, the box body 1 is closed and the flap 62 is joined to the inner surface of the first surface 11. The first divided body 51 and the second divided body 52 are locked by the two auxiliary surfaces 22. Thus, the state where the box 1 is sealed is maintained by the lock mechanism formed by the first auxiliary surface 21 and the second auxiliary surface 22. When the locking piece 11a formed on the side close to the sixth surface 16 of the first surface 11 is inserted into the first auxiliary surface 21 and locked to the locked portion 63, the box 1 is more preferably used. The sealed state can be maintained.

The box 1 of the present embodiment having the above-described structure can be easily and efficiently manufactured from a single blank sheet.
FIG. 4 is a view showing a blank sheet 101 for forming the box 1. The top surface 31 and the ground 32 are directly connected to the second surface 12 via a fold line. Similarly, the second top surface 41 and the second ground 42 are directly connected to the fifth surface 15 via a broken line. Tongues that serve as gluing surfaces to the top and bottom to be joined to the top and bottom ends of the first surface 11, the third surface 13, the fourth surface 14, the fifth surface 15, and the first auxiliary surface 21, respectively. The pieces 71 are connected via a folding line. Each tongue piece 71 is formed in a trapezoidal shape or a substantially triangular shape so that the width gradually decreases toward both sides of the top and bottom direction.

On the top surface 31 and the ground surface 32, a perforation (second separation auxiliary line) 75 that is cut off when opened is formed. One end portion of the perforation 75 is located at an intermediate portion P1 of the side facing the fold line that becomes the boundary with the second surface among the sides of the top surface 31 and the ground 32, and the other end portion is the top surface. Among the vertices of the surface 31 and the ground surface 32, it is located at a position P2 in the vicinity of the

vertices

72a and 72b located closest to the third surface 13 side. The position P2 is located farther from the second surface 12 than the

vertices

72a and 72b, and when the tongue piece 71 is joined to the top surface 31 and the ground 32, the perforation 75 and the tongue piece 71 do not overlap. Is set to

Both ends of the perforation 61 for separating the first auxiliary surface 21 and the second auxiliary surface 22 are located on the second auxiliary surface 22. The perforation 61 extends from both ends toward the intermediate portion in the vertical direction, and then smoothly bends toward the first auxiliary surface 21 and further extends toward the intermediate portion in the vertical direction. The first surface 16 is displaced toward the sixth surface 16 and then connected in a vertical direction. Thereby, the perforation 61 has the 1st area | region 61a of the both ends for forming the flap 62, and the intermediate | middle area | region 61b which forms the to-be-latched part 63 and connects the two 1st area | regions 61a. Yes.
Of the eight surfaces constituting the side surface of the box 1, the first surface 11 and the second auxiliary surface 22 are narrower than the other surfaces.

An example of a procedure for manufacturing the box 1 filled with contents from the blank sheet 101 will be described. In the following description, it is assumed that the surface of the blank sheet 101 shown in FIG. 4 is the surface that forms the outer surface of the box 1.

In the blank sheet 101, an easy-release agent such as a release varnish is applied to at least one of the first auxiliary surface 21 and the second auxiliary surface 22 in advance by printing or the like. At this time, you may print the information regarding the content, the design which exhibits the designability, etc. with an easy-release agent on the other surface.

Next, a bonding material such as glue or adhesive is applied to the surface of the second auxiliary surface 22 in a line extending in the vertical direction, and a folding line that is a boundary line between the first auxiliary surface 21 and the second auxiliary surface 22 The second auxiliary surface 22 is bent to the front side along L 1 and joined to the first auxiliary surface 21. FIG. 5 shows a state in which the second auxiliary surface 22 and the first auxiliary surface 21 are joined. The first auxiliary surface 21 and the second auxiliary surface 22 are temporarily fixed to the extent that they can be peeled off by applying a light force while maintaining a substantially flat sheet shape with a bonding material and an easy-release agent. Yes. The easy release agent is preferably applied only on the first auxiliary surface 21. If it does in this way, when a box is opened, since an easy peeling agent adheres to the 2nd auxiliary surface side by all means, there exists an advantage that a joining material cannot stick easily to a user's hand.

Next, the first auxiliary surface 21 to which the second auxiliary surface 22 is temporarily fixed is bent to the back side along a fold line L2 that is a boundary line with the sixth surface 16. FIG. 6 shows a state where the first auxiliary surface 21 is bent to the back side. FIG. 5 shows the blank sheet 101 turned upside down for the sake of explanation, and the perforation 61 formed on the first auxiliary surface 21 is indicated by a broken line.

Next, a bonding material is applied to the back surface of the second auxiliary surface 22 in a linear shape extending in the vertical direction, and a region where the second divided body is formed is a fold line L3 between the third surface 13 and the fourth surface 14. The back surface of the first surface 11 and the back surface of the second auxiliary surface 22 are joined together. At this time, the bonding material is applied to avoid the portion 62a so that the portion 62a to be the flap is not bonded to the first surface 11. An easy-release agent may be applied in advance to the back surface of the portion 62a so that it can be easily peeled off even if the bonding material is accidentally applied to the portion 62a and bonded.

Through the steps so far, as shown in FIG. 7, a cylindrical intermediate body 102 that can be assembled to the box 1 is formed. In the intermediate body 102, eight surfaces forming the side surfaces of the hexagonal columnar box 1 are connected in the circumferential direction of the box 1 in a state where a sealed state can be realized.

After the formation of the intermediate body 102, the contents are filled. A fold line on the side surface of the intermediate body 102 is appropriately bent to form a hexagonal cross section with an open top, and the contents are filled into the internal space from any open top. Then, after bending the tongue piece 71 of the 4th surface 14, the 6th surface 16, and the 1st auxiliary | assistant surface 21, the 2nd top surface 41 and the 2nd ground 42 are bent, and it joins with the tongue piece 71 with a joining material. Next, the tongue piece 71 of the first surface 11 and the third surface 13 is bent. Finally, when the bent top surface 31 and the ground 32 and the tongue piece 71 are joined, and the substantially quadrangular region surrounded by the perforation 75 is spot-joined with the second top surface 41 and the second ground 42, the contents The box 1 filled with and sealed is completed.

When the user opens the box 1, the top surface 31 and the ground 32 are cut into two along the perforations 75. As a result, the portion joined to the second top surface 41 and the second ground 42 remains on the second top surface 41 and the second ground 42, and the remaining portion is against the second top surface 41 and the second ground 42. Can be moved. Thereby, opening as shown in FIG. 3 is attained.

As described above, according to the box 1 of the present embodiment, the first auxiliary surface 21 and the second auxiliary surface 22 that are connected to one of the side surfaces are provided, and the first auxiliary surface and the second auxiliary surface are provided. A perforation 61 that functions as a separation auxiliary line that enables separation from the surface is provided. The second auxiliary surface 22 is folded outward and joined to one of the side surfaces where the first auxiliary surface is not continuously provided, so that the side surface can be opened and the side surface is sealed before opening. The body 102 can be formed.
Here, the folding lines L1, L2, and L3 that are bent to form the intermediate body 102 all extend in the vertical direction and are parallel to each other, and a bonding material for bonding the second auxiliary surface 22 to the first surface 11 Since it is applied so as to extend in the vertical direction, all the steps for forming the intermediate body 102 can be executed by appropriately setting a known sack pasting machine. As a result, the filling and sealing of the contents into the intermediate body 102 can be easily performed only by modifying or changing the setting of a highly versatile filling and packaging facility on a small scale. Therefore, the box 1 can be manufactured regardless of the method of forming the contents while wrapping the contents in the blank sheet, and all steps of forming the intermediate from the blank sheet 101, filling the contents, and sealing are efficiently performed. It can be carried out.

Further, the perforation 61 for separating the first auxiliary surface 21 and the second auxiliary surface 22 has a first region 61a for forming the flap 62, and has a locking function when the flap 62 is resealed after opening. Demonstrate. That is, when the intermediate body 102 is formed, the lock mechanism for resealing has already been constructed, so that it is not necessary to construct a lock mechanism separately from the assembly of the box. As a result, it is possible to provide a box that can be efficiently manufactured and the required manufacturing accuracy is not excessively high, and that can be efficiently manufactured while having a lock mechanism.

Furthermore, since the tongue piece 71 to be joined to the ceiling is formed in a substantially triangular or trapezoidal shape, the tongue pieces are prevented from interfering with each other when joined.

Furthermore, one end portion of the perforation 75 for separating the top surface 31 and the ground surface 32 from the second top surface 41 and the second ground surface 42 that are spot-joined is the It is located in the vicinity of the

vertices

72a and 72b located at both ends of the broken line L3 that becomes the boundary of the bifurcated body 52. Thereby, the level | step difference in the shape of the top surface 31 and the ground 32 which becomes movable with respect to the 2nd top surface 41 and the 2nd ground 42 decreases, and the 2nd top surface 41 and the 2nd ground 42 are top surfaces at the time of resealing. It is possible to suitably suppress problems such as moving outside 31 and the ground 32 and being caught by the step so that the box 1 cannot be closed.

Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, and various modifications may be made to each component without departing from the spirit of the present invention. It is possible to delete or combine the configurations of the embodiments.

For example, in the present invention, the locking piece and the locked portion are not essential. In other words, the resealing can be performed without any problem even with the flap 62 alone, and the locking piece and the locked portion are merely auxiliary structures for ensuring the resealing.
In addition, the size, shape, number, etc. of the flaps may be changed as appropriate by changing the shape of the perforation 61, and the tongue piece 71 is provided on one or both of the ceilings, not on the side surface. May be. Furthermore, the shape of the perforation 75 may be changed so that both ends are positioned in the vicinity of the top surface and the top of the ground, or the width dimension of the first surface may be the same as that of the other side surface.

Furthermore, the shape of the box of the present invention is not limited to the substantially hexagonal column shape described above. Accordingly, various polygonal column shapes such as a substantially triangular column shape can be used. However, if the shape is substantially triangular, the inner angle of the top and bottom is reduced, and it may be difficult to open. Therefore, it is preferable that the top and bottom be in the shape of another prism having four or more corners.

In addition, the contents to be stored are not limited to foods, but can naturally be applied to a box for storing various contents.
