Description

  The present invention relates to an improvement in a partitioning piece structure of a storage box for storing a plurality of articles in series in a storage box while partitioning a plurality of articles individually.

Conventionally, for example, Japanese Utility Model Application No. 60-15817 discloses a structure of a partition plate for preventing moss and the like from colliding with each other in order to pack moss. A partition wall formed in combination, a partition fin formed by cutting each side of the partition wall to have the same width so as to partition adjacent moss, and a folding formation from the lower part of each partition wall The pair of bottom plates provided with the locking portions for locking the leg portions of the partition fins, and the one bottom plate and the other bottom plate are connected so that the protruding directions from the side edges in the longitudinal direction are different. A configuration including an abutting portion is disclosed.
As a result, in the empty state before inserting the moss into the packaging box, the bottom plate is bent obliquely upward at the partition position where the partition fin is bent at a right angle, and the locking portion of the bottom plate is locked to the partition fin. Thus, the partition fin can be restrained at the partition position.
Further, when inserting the moss, the moss is inserted all at once, so that the bottom plate and the partition fins are disengaged at the same time due to the weight of the moss, and the bottom plate is in a horizontal state. Functions as a partition between mosses.
Further, the engaging portion of the bottom plate is fitted to the lower end of the leg portion of the partition fin even when the bottom plate is horizontal, and restrains the partition fin at the partition position.
However, since the bottom plate is integrally formed when storing the moss, when the moss arranged in series is separately inserted, the bottom plate is pushed down by the moss inserted first.
In particular, when the space is divided into three spaces with two partition fins, when the moss is first inserted into one of the spaces, the bottom plate is loaded with a load only on the side where the moss is placed. Since it falls down, the whole may not become a horizontal surface, and there is a possibility that the remaining two partition fins that do not contact the moss cannot be held in the partition position.
Therefore, the moss must be inserted so as to be in contact with the bottom plate at the same time, and there is a problem that the moss cannot be stored in an arbitrary partition space in an appropriate order.
In addition, the lower end of the leg portion of the partition fin needs to be formed so as to protrude from the lower folding line for folding the bottom plate to the bottom plate side by the length that fits the engaging portion in order to fit the engaging fin.

[Partition piece]
The partition piece structure shown in FIGS. 1 to 4 is configured to be used when the storage box 30 is divided into two parts and articles are stored side by side in series.
The partition piece 1 uses a substrate 1A made of cardboard, cardboard, thin plate, or the like made of paper or synthetic resin, and extends left and right at an intermediate position in the vertical direction so that the substrate 1A is separated from the upper partition main body 10 and the lower bottom plate. A transverse folding curve L1 for valley folding that bisects the portion 20 is provided.

[Partition piece]
The partition main body 10 includes a vertical folding curve 11 extending vertically from the upper end to the middle position at a midway position (center in the illustrated example) of the substrate 1A, and an end of the horizontal folding curve from the lower end of the vertical folding curve. A cut line 12 extending in an arc shape of approximately ¼ circle, and a partition piece portion 13 formed on the side where the upper and lower sides are separated from the lower end of the cut line 12 along the extension line of the lateral folding curve L1. And a back plate piece 19 formed on the opposite side of the vertical folding curve 11.

[Fitting port]
The partition piece portion 13 has a substantially rectangular shape with a lower portion cut out in an arc shape, and has a fitting opening portion 14 formed of a long hole extending obliquely toward the lower side.
[Bottom plate part]
The bottom plate portion 20 is composed of two bottom piece portions 25 separated by a bottom plate slit 21 extending from the horizontal folding curve L1 to the lower end on the extension line of the vertical folding curve 11.

[Bottom plate slit]
The bottom plate slit 21 that separates the adjacent bottom piece portions 25 has a straight portion 21a that extends on the extension line of the vertical folding curve 11 starting from a position in contact with the horizontal folding curve L1.
Further, on the front end side of the straight portion 21a, a rear convex portion 22 is formed on one bottom piece portion 25 so as to protrude toward the other bottom piece portion (referred to as 25 'for convenience of explanation), and the other bottom piece portion 25' is formed. The front convex part 23 which protrudes toward one bottom piece part 25 is formed.

  And when the said partition piece part 13 is bent at right angle with respect to the backplate piece part 19 along the vertical fold curve 11, the insertion opening part 14 slanted each bottom piece part 25 along the horizontal fold curve L1. When bent upward, the rear convex portion 22 fits behind the fitting port portion 14, and the front convex portion 23 fits in front of the fitting port portion 14.

In the illustrated example, a rear convex portion 22 is formed on the bottom piece portion 25 corresponding to the back plate piece portion 19, and a front convex portion 23 is formed on the bottom piece portion 25 ′ corresponding to the partition piece portion 13.
The partition piece 13 is folded at a right angle with respect to the back plate piece 19 by folding the vertical folding curve 11 into a valley.

  Further, the two bottom piece portions 25, 25 ′ are valley-folded along the lateral folding curve L1 and bent obliquely upward, and at a predetermined inclination position, the rear convex portion 22 formed on the bottom piece portions 25, 25 ′, The front projection 23 is fitted into the fitting opening 14 of the partition piece 13 from both the left and right sides.

Since the rear convex portion 22 and the front convex portion 23 are displaced from each other in the front-rear direction, the rear convex portion 22 and the front convex portion 23 are hooked separately and independently without overlapping each other in the long hole fitting opening portion 14.
In the state where the bottom piece portion 25 is locked to the partition piece portion 13 as described above, the space is inserted into the storage box 30 and partitioned by the partition piece portion 13 as shown in FIG.

Therefore, when the article is inserted into the space partitioned by the partition piece portion 13, the load of the article is applied to the bottom piece portion 25 (or 25 ′), and the rear convex portion 22 or the front convex portion provided integrally with the bottom piece portion 25. Only 23 is disengaged from the fitting opening 14, and the bottom piece 25 (or 25 ') returns to the original horizontal posture.
Since the bottom piece 25 ′ (or 25) to which no load is applied is maintained as it is, the partition piece 13 can maintain a right-angled partition position.
As a result, the partition piece 25 does not swing or displace when the article is inserted first into any of the plurality of partition spaces (see FIG. 4A).

[Cutting line]
In addition, the cut line 12 has a ¼-circular arc shape, and a latching step portion 15 is formed on the extension of the fitting port portion 14 in the inclined direction. A large-diameter arc portion 16 is formed therethrough.

The locking piece portion 18 has a shape that can be fitted into a locking hole 26 described later, and is formed by cutting out the bottom side cut off from the bottom piece portion 25 of the partition piece portion 13.

The locking hole 26 is formed along the bottom plate slit 21. The locking piece portion 18 is combined with the adjacent bottom piece 25 displaced in the horizontal posture on the side closer to the lateral folding curve than the rear convex portion 22. It consists of a rectangular hole that fits.
That is, the straight portion 21 a of the bottom plate slit 21 is a rectangular long side, and the bottom plate slit 21 is cut into a rectangular shape toward the bottom piece portion 25 ′ facing the partition piece portion 13.

  And the edge part 26a close | similar to the horizontal folding curve of the locking hole 26 cut out in the rectangle to the said bottom piece part 25 'side inclines bottom piece part 25', and the front convex part 23 is said fitting opening part 14 When it is locked, the latching step portion 15 is locked.

  Further, when the adjacent bottom piece 25 descends and returns to the horizontal posture, the linear portion 21a of the bottom plate slit 21 and the rear convex portion 22 are combined to form a locking hole 26, and the locking hole is formed as described above. 26, the locking piece 18 enters (see FIG. 4B).

In addition, the back convex part 22 and the front convex part 23 which removed from the insertion opening part 14 form a horizontal surface, and abutting with the bottom part cut | disconnected from the latching piece part 18 of the partition piece part 13 is carried out.
Thereby, even if it is a case where articles | goods are taken out from a storage box, the attitude | position of the partition piece part 13 can be restrained to a partition position.

In the above-described embodiment, the case where there is one partition piece 13 and partitions the two storage spaces has been described, but two partition piece portions 13 may be provided to partition the three storage spaces.
