Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corrugated cardboard partition frame that partitions the interior of the packaging box body into a predetermined area, and in particular, enables easy and quick assembly and creation of the partition frame, and yet further strengthens the rigidity of the partition frame. The present invention relates to a cardboard simple partition frame for a packaging box, which enables packaging of relatively heavy and small products.

[0002]

[Prior art]

 The conventional corrugated cardboard partition frame for this type of packaging box has a vertical partition frame with notched grooves at regular intervals, and a lateral groove provided with notched grooves that intersect with the notched grooves of this vertical partition at a right angle. It is generally constructed by assembling a partition frame and a box.

Since such a conventional assembling partition frame has low strength and weak rigidity, when a relatively heavy and small product is packaged, the partition frame may be deformed due to vibration or shock during transportation, or its end surface may be damaged. Crushing occurs, and there is a drawback that it cannot fully fulfill the role of holding the product.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to enable easy and quick assembly and production of a corrugated cardboard partition frame that partitions the space of the packaging box body into a predetermined rectangular area, and to strengthen the rigidity of the partition frame. Therefore, it is intended to obtain a cardboard simple partition frame for a packaging box that can sufficiently hold a small product which is relatively heavy.

[0005]

[Means for Solving the Problems]

 The present invention has been made in view of the above viewpoints, and includes a plurality of strip-shaped corrugated cardboard horizontal strips having a predetermined width and a predetermined length, and a required length having substantially the same width as the horizontal strip. It consists of a plurality of corrugated vertical strips of corrugated cardboard, and the horizontal strip has a punching groove in the center with a partitioning interval of a specified width in its center and ears half the length of the partitioning at both ends. The end punched groove with one piece and one or more intermediate punched grooves that are evenly spaced between each of the end punched grooves and the center punched groove at the shortest position thereof are located below. The vertical strip is provided with a folding curve that defines the partition space and a folding curve that defines both end ears, and the vertical strip has punched grooves of the horizontal strip at both ends thereof. A step box for a packaging box, in which a step part that fits in the upper part and a partition groove that opens upward with a distance corresponding to the partition interval of the horizontal band are provided between the step parts. It is intended to provide Le Made Simple partition frame.

[0006]

[Action and Example]

 An embodiment of the present invention will be described below with reference to the drawings, along with its operation. A plurality of strip-shaped corrugated cardboard horizontal strips 1 having a predetermined width and a predetermined length are formed. Then, a plurality of vertical corrugated strips 11 made of corrugated board having a required length and having substantially the same width as the horizontal strip 1 are formed.

As shown in FIG. 1, the one lateral strip 1 has central punching grooves 3 and 3 having a partitioning interval 2 having a predetermined width in the central portion thereof, and the partitioning portions at both ends thereof. Of the end punching grooves 5 and 5 having the half-length selvages 4 and 4, and the end punching grooves 5 and the corresponding central punching groove 3 at the shortest position. An intermediate punching groove 6 in the middle of the space is opened downward and cut. Further, folding lines 7 and 7 are arranged at positions that define the partition space 2, and folding lines 8 and 8 are arranged at positions that define the two end pieces 4 respectively.

As shown in FIG. 2, the other vertical strip 11 has stepped portions 12 at both ends which are fitted in the punching grooves of the horizontal strip 1 at the lower part thereof. . A partition groove 14 is opened between the two step portions 12 at an interval 13 corresponding to the partition interval 2 of the horizontal strip 1 and opening upward.

Therefore, as shown in FIG. 3, a plurality of the horizontal strips 1 and a plurality of the vertical strips 11 are assembled by intersecting at right angles in a grid pattern. At the time of assembly, as shown in the state of being separated and pulled up in FIG. 3, first, the folding curves 7 and 7 of the corrugated cardboard horizontal strip 1 are respectively bent inward at right angles, and the folding curves 8 at both ends are When 8 are bent inward at right angles, the partition space 2 is formed on one side in the longitudinal direction, and the ear pieces 4, 4 are abutted on the other side, so that the same space as the partition space 2 is formed. A quadrilateral partition frame A is formed.

The first and last partition frame bodies A are formed with central punching grooves 3 and 3, end punching grooves 5 and 5, and intermediate punching grooves 6 and 6 formed at both ends in the longitudinal direction. Are respectively fitted to the step portion 12 of the vertical strip 11 and the partition groove 14 at the position adjacent thereto.

The partition frame A arranged in the middle of each of the vertical strips 11 has the central punching grooves 3, 3 and the end punching grooves 5, 5, which are sequentially formed at both longitudinal ends thereof. The intermediate punching grooves 6, 6 are fitted into the adjacent dividing grooves 14 of the separate vertical strips 11, respectively.

As described above, the partition frame obtained by fitting and assembling the plurality of horizontal strips 1 and the plurality of vertical strips 11 is assembled inside the packaging box body 21. 22 is a packaging box lid.

In the partition frame assembled as described above, the strength of the partition frame is remarkably strengthened because the double ends of the horizontal strip 1 and the vertical strip 11 constitute the double wall at both ends in the longitudinal direction. . Moreover, since the lateral strip 1 has a long quadrilateral shape, it is strengthened against collapse.

[0014]

[Effect of device]

 As is apparent from the above description, according to the present invention, it is possible to easily and quickly assemble and create a corrugated board partition frame that partitions the space of the packaging box body into a predetermined area, and in particular, the partition frame Since it can be toughly strengthened, even small products that are relatively heavy can be fully packaged and held.
