Description

The present invention relates to a box-shaped storage case for storing and packaging a product in a box-shaped container.

  As a box with a lid for packaging that is assembled and used in a flat folded state, conventionally, a bevel mountain fold line from the front corner of the bottom plate to the edge of the front plate, and the edge of the side plate from the rear corner of the bottom plate And a slope fold line extending from the front corner of the top plate to the edge of the lid front plate is disclosed (for example, see Patent Document 1). In this box with a lid, in the folded state, the front plate, both side plates and the front plate of the lid are folded along the oblique mountain fold line, oblique valley fold line and oblique mountain fold line, respectively, so that the bottom plate and the rear plate overlap. Folded. By simply raising the rear plate from the bottom plate and extending the folding of the front plate, both side plates, the front plate of the lid or the lid side plate, it is possible to quickly squeeze from a flat folded state without the need to fold or hold the connecting piece. It can be assembled.

  Conventionally, as a cardboard one-touch case, the inner bottom flaps are superposed on the bottom surface of the corner where the paste is pasted and the outer bottom flaps in contact with the bottom surface of the corner opposite to the corner in a diagonal direction. Are disclosed in which each is bonded with an adhesive (for example, see Patent Document 2). This is because, in each of the inner bottom flaps, in each of the diagonal fold lines provided in the central part of the diagonal fold line provided in accordance with the line that bisects each corner in each outer bottom flap, Each tongue piece provided so as to protrude from the joining edge provided to be joined is inserted, and each tongue piece is bonded to the outer surface of each outer bottom flap with an adhesive, It is said that the strength at the bonded corner is strengthened.

  However, the above-mentioned box with lid and one-touch case made of cardboard lack strength at the assembling boundary such as the bottom, and the contents can be easily seen or tampered from the gap or the bonded portion of the bottom. In particular, the one-touch case made of cardboard, which will be described later, can increase the locking strength of the bottom, but it can be easily inserted from the edge of the bottom flap to be abutted. The effect would be reduced.

  In addition, other conventional anti-tampering functions, such as shrink wrapping and sealing, have been proposed. However, these require separate members and processes, which is troublesome in terms of management and work, and has high productivity. It was not a thing.

  In particular, the above-mentioned box with lid is such that a relatively large side plate provided on the left and right sides is folded into a folded state, and a complicated folded-back operation is required to produce a folded state mechanically. It was not possible to improve productivity.

  Therefore, an object of the present invention is to provide a box-type storage case with good productivity, which can prevent the container from being tampered with or tampered with after the assembly.

The present invention employs the following means in order to solve the above problems.
The box-shaped storage case of the present invention is
A side plate that has a front plate 11, an inner side plate 13, a back plate 12, and an outer side plate 14 that are connected laterally, and that is formed into a rectangular tube by bending each of the connecting sides;
A first flap plate 21 co-connected to the lower side of the front plate 11 and the lower side of one adjacent side plate (the inner side plate 13 or the outer side plate 14);
A second flap plate 22 co-connected to a lower side of the back plate 12 and a lower side of another adjacent side plate (outer side plate 14 or inner side plate 13);
In the box-shaped container that constitutes the bottomed box body by abutting the first flap plate 21 and the second flap plate 22 along the box bottom surface,
At the center in the width direction of the first flap plate 21 and the second flap plate 22 are formed lock pieces 23 and 24 that protrude in the diagonal direction of the rectangular shape at the bottom, respectively.
With the first flap plate 21 and the second flap plate 22 butted together, the lock piece 23 and the lock piece 24 are locked together at the bottom center,
The first flaps 21, each of the second flaps 22, the first pinching piece 31 extending toward the box upward when the box forming the shape, the second pinching piece 32 is extended,
The first pinching piece 31, by the second pinching piece 32 extends inclined to the box obliquely outward, seen write sandwiched contained goods in the box from the back plate 12 side and the front plate 11 side,
Further, a first side plate 51, a second side plate 52, and a third side plate 53 are sequentially connected to the outer side from the bonded side plate 15 connected to the back plate 12, and the back side of the third side plate 53 is the back plate 12. By being bonded to the inner surface, a three-side frame is formed in the square tube of the housing case, and a bottom partition plate 54 that is longer than the second side plate 52 is disposed on the third side plate 53 in a direction opposite to the connecting direction. When the rectangular tube is assembled, the bottom partition plate 54 obliquely crosses the inside of the three-side frame and forms a bottom partition for supporting the second container in the three-side frame. A box-shaped storage case characterized by being formed into

  The inner side plate 13 and the outer side plate 14 have a common side plate width 13W, and the first flap plate 21 and the second flap plate 22 have a common flap plate width 22W. The flap plate width 22W is larger than the side plate width 13W. It is 80%, preferably 60% of the side plate width 13W at most. And when assembling from the folded state to the box state, the boundary between the first flap plate 21 and the second flap plate 22 is taken as the folding side, and the first sandwiching piece 31 and the second sandwiching piece 32 respectively extended beyond the border. Fold the mountain side into the box. Due to the folding property of the formed paper at this time, the front end sides 311 and 321 of the first sandwiching piece 31 and the second sandwiching piece 32 are pressed against the inner surfaces of the front plate 11 and the back plate 12, respectively (FIG. 3).

  In addition, the sandwiching pieces 31 and 32 are composed of two plate surfaces connected to each other at the valley fold side, and in the process of changing from the folded state to the assembled state, the tip sides of the sandwiching pieces 31 and 32 are bordered by the corner portion, The sandwiching pieces 31 and 32 are raised with the angle twisted in the width direction with respect to the front plate and the back plate. At this time, the sandwiching pieces 31 and 32 are formed so that the tip side is inclined so that the inner portion in the width direction is short and the outer portion in the width direction is long. It is possible to prevent the tip portion from colliding and the tip portion on the outer side in the same width direction from floating from the front plate / back plate. And each pinching piece is arranged in an inverted cross-section direction without rising from the inner surface of the box, so that there is no excessive lifting of the contained material, and the contained material can be securely sandwiched between the sandwiching pieces. it can.

  Further, the sandwiching pieces 31 and 32 are reinforced by the formation of ribs, so that unnecessary bending and bending in the extending direction can be prevented, and the contents can be securely sandwiched. In the embodiment, four ribs 30 are formed at equal intervals by elongated oval stamping (ruled line processing).

  The box-shaped storage case of the present invention takes the above-described means, and the sandwiching plates are alternately extended in the box at the bottom where the internal tampering is easy, and the contents are sandwiched from the outside in the covering direction of the flap plate. Will be housed. Thereby, it became the box-type accommodation case which can prevent that the unauthorized opening of the accommodation thing and the alteration to the accommodation object were performed after an assembly. In addition, since the formation of the side square box and the flap plate can be formed planarly by the folding process and the bonding process, the folding workability can be improved, such as bonding with a sack machine is possible, It became a box-type storage case with good productivity.

In addition, a lead ruler is provided on the substantially horizontal connecting side, and the first and second sandwiching pieces 31 and 32 on the front side are surely folded.

  The front end side 311 of the first sandwiching piece 31 and the front end side 321 of the second sandwiching plate 32 are inclined downward from the side in the width direction toward the center, respectively, to prevent lifting from the inner surface of the box. The inclination angles 311θ of the tip sides 311 and 321 are both approximately 5 to 15 degrees with respect to the horizontal.

  Further, the side sides closer to the center in the width direction of the first and second sandwiching pieces 31 and 32 extend to the inner position reaching the center in the width direction of the lock pieces 23 and 24, and the first and second sandwiching pieces 31 and 32. The width of each piece is maximized so that they do not overlap each other, so that the pinching function is more reliable. In this way, the lateral sides closer to the center in the width direction that are closer to the inside by widening the sandwiching pieces 31 and 32 are notches 312 and 322 in the vicinity of the connection portions with the flap plates 21 and 22 and from the center in the width direction to the outside. Is forming. By keeping a certain distance from the lock pieces 23 and 24 by the notches 312 and 322, interference between the pieces is prevented. The cut angles 312θ of the cuts 312 and 322 in the embodiment are both approximately 45 degrees with respect to the horizontal.

  The first sandwiching piece 31 and the second sandwiching piece 32 are folded back above the box when the box is formed, and extend obliquely outward in the box so that the contents in the box are moved to the front plate 11 side and the back plate. It will be in the state of sandwiching from the 12 side. Therefore, the flap plate width 22W of the first and second flap plates is 60% to 80% of the side plate width 13W.

(Partition section)
The middle partition portion is formed by sequentially connecting the first side plate 51, the second side plate 52, and the third side plate 53 from the bonding side plate 15 to the outer side, and the back side of the third side plate 53 is bonded to the inner surface of the back plate 12. By matching, a three-sided frame is formed in the square tube of the housing case. A bottom partition plate 54 that is slightly longer than the second side plate 52 is laterally connected to the third side plate 53 in a direction opposite to the connecting direction. The bottom partition plate 54 obliquely crosses the inside of the three-side frame when the rectangular tube is assembled, and constitutes a bottom portion for supporting the second container B2 in the three-side frame.

(Assembling method)
To assemble the box-shaped storage case configured as described above, the connected side plates are raised in a square tube shape, the first flap plate 21 and the second flap plate 22 are brought into contact with each other, and the lock piece 23 and the lock piece 24 are placed at the bottom. Insert into the end flap plates so that they are locked together at the center. Thereby, it can assemble to the box state which has a bottom part as shown in FIG.

  Example 2 does not have a partition part compared with Example 1. FIG. The lock pieces 23 and 24 are partially arc-shaped, and a small cut is formed at the end on the side of the mating side. Further, the front end sides 311 and 321 of the sandwiching pieces 31 and 32 are formed perpendicular to the extending direction, that is, in the horizontal direction, and are not inclined sides as in the first embodiment. Other configurations and usage methods not specifically mentioned are the same as those in the first embodiment.

  According to the second embodiment, as shown in FIG. 8, the raised portion 3 </ b> D with respect to the front plate / back plate is formed on the outer side in the width direction of the front end sides 311, 321 of the sandwiching pieces 31, 32 during assembly. This is based on the fact that each of the flap plates 21 and 22 has valley fold sides 21F and 22F, and rises while twisting during assembly. Although there is a possibility that the contents are accidentally entered into the floating portion 3D, the sandwiching pieces 31 and 32 are arranged closer to the contents, so that the contents can be securely sandwiched.
