Description

  The present invention relates to a partition and a packaging material set.

  When storing a plurality of articles in a cardboard box, a partition plate formed from a cardboard sheet may be inserted between the articles so that the articles do not directly contact each other. For example, when bottled beverages and the like are arranged in rows and columns and stored in a box, a partition body in which two or more partition plates are provided with slits for engaging each other and combined in a cross shape or a cross-beam shape in plan view ( The partition is widely used.

  Further, a general corrugated cardboard box extends from a pair of long side surface panels and short side surface panels that are alternately arranged in the left-right direction, and an upper edge and a lower edge 2 of the long side surface panel. It is formed by assembling a box sheet having a pair of outer flaps and two pairs of inner flaps extending from the upper and lower edges of the short side panel. More specifically, a general corrugated cardboard box is formed by connecting four side panels in a square cylinder shape and sealing the upper and lower openings of the square cylinder body with an inner flap and an outer flap. In a general corrugated cardboard box, the extension length of the outer flap and the inner flap is about half of the length in the left-right direction of the short side panel, and the outer flap is folded and opposed to the outside where the inner flap is folded. The opening of the rectangular cylindrical body formed from the side panel is sealed by bringing the front end of the outer flap into a butted state.

  In such a cardboard box, there is a portion where the inner flap does not exist inside the bottom wall formed by the inner flap and the outer flap, and the portion where the inner flap does not exist is recessed by the thickness of the cardboard sheet. It has become. When a plurality of articles are stored in a cardboard box, the articles arranged in the recesses where no inner flap is present have a large play in the vertical direction and may be easily damaged due to vibration during transportation, for example.

  For this reason, when storing articles that are easily damaged by up and down play, a buried board formed from a cardboard sheet is fitted into a recess in which no inner flap exists in the cardboard box, so that the inner surface on the bottom side is substantially flush. A configuration or a configuration in which a bottom pad formed of a corrugated cardboard sheet is disposed on the entire inner surface of the bottom wall so that the inner surface on the bottom side is substantially flush may be employed.

  When using a buried plate, it is necessary to arrange the buried plate in the concave portion of the cardboard box before accommodating the article. However, the corrugated cardboard box before storing the articles may be in a state where the inner flap is lifted from the outer flap, and problems such as a buried plate entering between the inner flap and the outer flap are likely to occur. . In particular, when the above-mentioned partition body is used in addition to the buried plate, the partition body is inserted after the buried plate is placed in the cardboard box. The plate is easily displaced.

  On the other hand, Japanese Unexamined Patent Application Publication No. 2014-223926 proposes a partition body in which a bottom pad is integrated. In the partition described in the above publication, a side plate having a rectangular shape is arranged on the side edge of the long side partition plate (length direction partition member) so as to be in close contact with the short side panel of the box. By connecting the bottom pad (bottom plate) to the lower edge, the bottom pad is integrated. In this configuration, in addition to using the bottom pad that covers the entire bottom wall of the cardboard box, a side plate for connecting the bottom pad is required, so that the area of the corrugated cardboard sheet to be used is increased and the cost is increased. .

JP 2014-223926 A

  In view of the above problems, an object of the present invention is to provide a partition and a packaging material set that can form a partition body in which a corrugated cardboard sheet is used in a small area and a buried plate is integrated.

  The assembly partition according to one aspect of the present invention made to solve the above problems is a partition formed from a corrugated cardboard sheet and arranged in the corrugated cardboard box in an assembled state to partition the internal space of the corrugated cardboard box, A short side center partition plate having a first slit extending downward from the upper edge, and a long side having a second slit extending upward from the lower edge and meshing with the first slit, and combined with the short side center partition plate Including a partition plate and a buried plate that is connected to a lower edge of the short side central partition plate and fits into a recess inside the bottom wall of the cardboard box, wherein the short side central partition plate and the buried plate are It is connected below one slit, the short side central partition plate has a notch below a portion without the first slit, and the buried plate has a convex part complementary to the notch.

  In the assembly partition, since the buried plate is continuously provided on the lower edge of the short side central partition plate, a partition body in which the buried plate is integrated can be formed. Moreover, the said partition has formed the notch in the short side center partition plate, and formed the convex part complementary to this notch in the buried plate, Therefore The area of a short side center partition plate and a buried plate is small. Further, by arranging the notches and the projections so as to mesh with each other, the center portion of the buried plate can be directly connected to the lower edge of the short side central partition plate. There is no need to provide an extra panel for alignment between the plate and the buried plate. Therefore, the assembled partition has a small use area of the cardboard sheet. Moreover, the said partition formed the 1st slit extended below from an upper edge in the short side center partition plate, and formed the 2nd slit extended upwards from the lower edge in the long side partition plate, Therefore A short side center partition A long side partition plate is engaged from above the plate to form a partition. For this reason, it is difficult to insert a finger between the partition body and the article in the package body in which the partition body formed by assembling the assembly partition is arranged in the cardboard box and the article is accommodated in the space partitioned by the partition body. In such a case, by first extracting the long side partition plate upward, a space for inserting a finger between the articles can be formed, and the article can be easily taken out.

  The partition has a third slit in which the long side partition plate extends downward from the upper edge, and has a fourth slit extending upward from the lower edge and meshing with the third slit, It is preferable to further include a short side outer partition plate combined with the long side partition plate so as to be arranged in parallel. Thus, when the said partition further includes the said short side outer side partition plate, the inside of a cardboard box can be divided into more divisions. In addition, the long side partition plate has a third slit extending downward from the upper edge, and the short side outer partition plate has a fourth slit extending upward from the lower edge, thereby extracting the long side partition plate upward. At the same time, the short side outer partition plate can be extracted. That is, the partition formed by assembling the assembly partition is the other partition plate except for the buried plate on which the article is placed in the package and the short side central partition plate connected to the buried plate. It is possible to easily remove the article by pulling it out from the cardboard box.

  In the assembly partition, it is preferable that the boundary between the lower edge of the short side central partition plate and the buried plate is defined by a half cut line obtained by cutting only one surface of the corrugated cardboard sheet. Thus, by demarcating the boundary between the short side central partition plate and the buried plate by the half cut line, it becomes easy to bend the buried plate with respect to the short side central partition plate.

  The partition includes a plurality of the long side partition plates, the short side center partition plate has the plurality of first slits, and the short side center partition plate and the buried plate include the plurality of first slits. It is preferable that they are respectively connected below the. As described above, the short side central partition plate and the buried plate are connected to each other below the plurality of first slits, thereby improving the strength of the short side central partition plate and reducing the short side central partition plate. The buried plate can be bent accurately.

  The packaging material set which concerns on another aspect of this invention is provided with the above-mentioned assembly partition and the sheet | seat for boxes which can be assembled in the cardboard box in which the said partition is arrange | positioned inside.

  Since the packaging material set includes the above-described partitioning, the use area of the corrugated cardboard sheet is relatively small, and the buried plate and the partition can be accurately arranged inside the corrugated cardboard box formed by assembling the box sheet. it can.

  In the present invention, the “assembly partition” is not limited to the one assembled in the partition body, and includes a set of a plurality of partition plates that can form the partition body by being combined.

  As described above, the assembly partition and the packaging material set according to the present invention have a small use area of the corrugated cardboard sheet and can form a partition body in which the buried plate is integrated.

It is a typical top view (development drawing) of the sheet | seat for boxes of the packaging material set of one Embodiment of this invention. It is a typical top view (development figure) which shows the decomposition | disassembly state of the partition of one Embodiment of this invention used with the sheet | seat for boxes of FIG.

<Partition>
The partition 2 of this embodiment is engaged with one short side central partition plate 31, one buried plate 32 provided continuously to the short side central partition plate 31, and the short side central partition plate 31. Two long-side partition plates 33 to be engaged, and two short-side outer partition plates 34 that engage with the two long-side partition plates 33.

  In the partition 2, each plate can be cut out from a single large cardboard sheet using a Thomson mold. FIG. 2 shows an example of the arrangement of the plates when the plates of the partition 2 are cut out from the base paper of the cardboard sheet using a Thomson mold. For this reason, the upper and lower orientations of the long side partition plate 33 on the upper side of the drawing and the short side outer side partition plate 34 on the lower side of the drawing are reversed. In addition, in FIG. 2, it is preferable that the direction of the ridgeline of the core of the corrugated cardboard sheet is the vertical direction.

  In the present specification, “upper” and “lower” mean the upper and lower sides in the assumed general usage of the partition formed by assembling the partition 2 and the box formed by assembling the box sheet 1. The “left-right direction” means a direction corresponding to the horizontal direction in the assumed general usage, but requires that the partition 2 and the box seat 1 are always held in this direction. is not.

(Short side center divider)
The short side center partition plate 31 has two first slits 35 extending downward from the upper edge. The short side central partition plate 31 has a notch 36 below the portion without the first slit 35, and the lower portions of the two first slits 35 are leg portions 37 respectively extending to the buried plate 32. Yes.

  The long side partition plate 33 is fitted in the first slit 35. For this reason, the first slit 35 is linearly formed with a width substantially equal to the average thickness of the corrugated cardboard sheet. The opening of the first slit 35 may be widened in a tapered shape so that the long side partition plate 33 can be easily received.

  The length of the first slit 35 is preferably approximately half the height of the short side central partition plate 31.

  Since the short side central partition plate 31 has the leg portions 37 to which the buried plates 32 are respectively connected below the first slits 35, the width of the leg portion 37 can be made relatively large. While improving the intensity | strength of the board 31, the buried board 32 can be bend | folded correctly with respect to the short side center partition plate 31. FIG.

  The first slit 35 is formed to extend downward from the upper edge of the short side central partition plate 31, and the first slit 35 is not formed on the lower edge of the short side central partition plate 31, thereby The connection length with the buried plate 32 can be made relatively large. In addition, since the first slit 35 is formed on the upper edge side of the short side central partition plate 31, the buried plate 32 does not interfere when the long side partition plate 33 is engaged with the short side central partition plate 31. There is no need to provide the plate 32 with a structure such as a slit through which the long side partition plate 33 passes.

(Burying board)
The buried plate 32 is connected to the lower edge of the short side central partition plate 31 and, as shown in FIG. 4, is a recess between the bottom flaps 22 and 23 inside the bottom wall of the cardboard box formed by assembling the box sheet 1. By fitting to, the step on the inner surface of the bottom wall of the cardboard box is substantially eliminated.

  More specifically, the buried plate 32 is connected to the short side central partition plate 31 and the first slit 35 as described above, and has a convex portion 38 complementary to the notch 36 of the short side central partition plate 31. There is an area where no corrugated cardboard sheet exists between the convex portions 38 of the buried board 32. Since the area where no corrugated cardboard sheet exists is arranged directly below the long side partition plate 33, articles stored in the cardboard box are Then, it is placed on the convex portion 38.

  Thus, by forming the notch 36 in the short side central partition plate 31 and forming the convex portion 38 on the buried plate 32, the short side central partition plate 31 is connected to the center in the vertical direction when the buried plate 32 is deployed. In the installed state, the short side central partition plate 31 and the buried plate 32 can be integrally formed from one cardboard sheet.

  Further, by connecting the short side central partition plate 31 and the buried plate 32 below the first slit 35, the portion that does not contribute to the height adjustment of the support surface of the article can be used as the leg portion 37. For this reason, since the assembly partition 2 can make the width | variety of the leg part 37 comparatively large, the intensity | strength of a short side center partition plate can be ensured.

(Long side divider)
The long side partition plate 33 extends upward from the center of the lower edge in the left-right direction, and engages with the first slit 35 of the short side center partition plate 31, and from the upper edges on both sides of the second slit 39 in the left-right direction. And a third slit 40 extending downward.

  The long side partition plate 33 is vertically combined with the short side central partition plate 31 by engaging the second slit 39 with the first slit 35 of the short side central partition plate 31. The shape of the second slit 39 and the third slit 40 of the long side partition plate 33 can be the same as the shape of the first slit 35 of the short side center partition plate 31.

  As shown in FIG. 5, the long side partition plate 33 is engaged with the short side center partition plate 31 from above, so that it is separated from the short side center partition plate 31 in the cardboard box formed by assembling the box sheet 1. can do. Therefore, with the article placed on the buried plate 32, the buried plate 32 that is obstructed by the article and the short side central partition plate 31 that is formed integrally with the buried plate 32 remain in the cardboard box. The long side partition plate 33 can be extracted from the cardboard box. Thus, by extracting the long side partition plate 33, the gap between the accommodated articles is increased, so that the articles can be easily taken out.

(Short side outer divider)
The short side outer partition plate 34 has two fourth slits 41 extending upward from the lower edge and meshing with the third slit 40 of each long side partition plate 33.

  The short-side outer partition plate 34 is vertically combined with the long-side partition plate 33 by engaging the fourth slit 41 with the third slit 40 and sandwiches the short-side center partition plate 31 so as to sandwich the short-side center partition plate. 31 is arranged in parallel. The shape of the fourth slit 41 of the short side outer partition plate 34 can be the same as the shape of the first slit 35 of the short side center partition plate 31.

  As shown in FIG. 5, since the short side outer partition plate 34 is engaged with the long side partition plate 33 from above, the long side partition plate 33 is extracted from the cardboard box formed by assembling the box sheet 1. The long side partition plate 33 is extracted from the cardboard box. As a result, the gap between the articles can be increased to further facilitate the removal of the articles.
