Description

  The present invention relates to a cardboard case, and more specifically, a case for storing a plurality of pack containers containing fruits and vegetables such as strawberries and other products, and the cardboard is hooked on the edge of the pack container for the storage. It is about the case.

  For example, fruits and vegetables such as strawberries, figs and butter are not directly stored in a cardboard case, but are stored in a cardboard case for each pack (usually 2 or 4 packs). Provided for distribution.

  A cardboard case using a pack container that has been conventionally used is stored by a method in which the bottom of the pack container directly touches the cardboard case. However, in that method, it is easy to cause a damage during distribution, and this damage causes a drop in the market price of fruit and vegetables and disposal, so it must be considered in packaging materials for shipping vegetables and fruits. There was no problem.

  As a countermeasure, a so-called suspended structure is considered in which the pack container is floated in the case so that the pack container does not directly touch the cardboard case. Further, there is a demand for a pack container suspended structure with an easy method so as not to increase the burden on the user. For example, the thing of Unexamined-Japanese-Patent No. 2005-15046 corresponds to this. However, what is described there is a tongue piece coming out from the side wall to hook the edge of the pack container, but this tongue piece makes the support of the pack container unstable, and the bottom surface of the pack container is in contact with the bottom surface of the case. There is a risk of contact.

  The thing of Unexamined-Japanese-Patent No. 2004-292054 is not only easy to slip because the part which hooks the semicircle edge of a cross section of a pack container is a flat surface, but all the four surrounding walls are double structures, There is a problem that the amount used is complicated and complicated, and it takes time to assemble.

  Japanese Patent Application Laid-Open No. 2005-35612 describes that the support piece formed on the short side wall of the case and hooking the short side of the pack container is not sufficient (particularly both ends), and inwardly. Not only is it easy to tilt, but the four-walled wall is a double wall, and there is a problem similar to that disclosed in Japanese Patent Application Laid-Open No. 2004-292054.

  Furthermore, in the thing of Unexamined-Japanese-Patent No. 2005-112448, in the 1st Example, since the short side of a pack container is hooked on the support piece arrange | positioned at the corner | angular part of a case, it is not stable, In the second embodiment, the support piece to which the short side of the pack container is hooked is bent from both side walls, and the inner end butting portion is engaged by the vertical partition piece, but the occlusion is not necessarily sufficient. Therefore, there is a possibility that it may come off due to an impact, and the pack container may not be sufficiently supported.

  In addition, although there is also a thing described in JP-A-2005-29257, this is provided with an abutting portion for supporting the pack container with an inclined surface from both sides and floating from the bottom surface of the case on the bottom surface of the case. This is for receiving and supporting the bottom surface of the pack container from below, and is different from the suspended state contemplated in the present invention.

  As described above, the cardboard case of the pack container suspended structure that has been proposed in the past has a high cost due to the large amount of cardboard paper material that cannot support the pack container in a stable state. Therefore, the present invention does not have such a problem, that is, it has a relatively simple configuration and is easy to assemble, and the both sides on the short side of each pack container are firmly and stable. Therefore, an object of the present invention is to provide a cardboard case that can reliably prevent damage to fruits and vegetables caused by the bottom of the pack container touching the cardboard case directly.

  The invention according to claim 1 for solving the above-mentioned problems is a container in which a corrugated cardboard material is bent and assembled into a box shape, and a cross-shaped partition that is fitted into the container and divides the container into four parts. The long wall of the container is formed by folding the long wall inner side surface forming part on the long outer side surface forming part connected to the bottom wall and then standing up, and the short wall of the container The forming portion includes a short outer surface forming portion continuously provided on the bottom wall, and a folded piece forming portion formed by extending the short outer surface forming portion on both sides and extending the both side extensions outward. A support wall forming portion provided between the outer extension portions of the folded piece forming portion at an appropriate interval from the short outer surface forming portion, and folding lines are formed on both sides of the support wall forming portion. The support wall forming portion and the short outer surface are formed when the container is assembled by the action of the folding line. Bets are corrugated board, characterized in that it is separated.

  Preferably, the partition is a cross-shaped partition composed of a horizontal partition and a vertical partition, and the horizontal partition is assembled in a U-shaped cross-section through connecting surfaces disposed at both end portions and an intermediate portion. The upper end of the surface extends upward between the connecting surfaces existing in the end portion and the intermediate portion and constitutes a support wall of the pack container.

  Since the cardboard case according to the present invention has the above-described configuration, it is relatively simple and easy to assemble, and can support both sides of the short side of each pack container in a stable and stable state. Thus, there is an effect of reliably preventing the damage of fruits and vegetables caused by the bottom of the pack container directly touching the cardboard case.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The cardboard case according to the present invention includes a container A and, for example, a cross-shaped partition B that is incorporated in the container A and partitions the container A. FIG. 1 shows a mount formed by punching a corrugated cardboard material for forming it. It is for storing four pack containers and includes a container forming part and a cross-shaped partition forming part. A solid line in the mount indicates a cut line, and a broken line indicates a folding line.

  First, the container forming portion will be described. In the figure, reference numeral 1 denotes a bottom wall of the container, and both long sides thereof (the left and right sides in FIG. 1. The long walls 4a and 4a which are double walls are installed. In order to form the long walls 4a and 4a, the long wall outer surface forming portions 2 and 2 are provided continuously on both long sides of the bottom wall 1, and the outer sides of the long walls 4a and 4a are formed via the frame forming portions 3 and 3 respectively. Long wall inner side surface formation parts 4 and 4 are provided in a row. In addition, two insertion holes 6 and 7 are formed along the folding lines 5 and 5 between the bottom wall 1 and the long wall outer surface forming portions 2 and 2 respectively. Insertion protrusions 8 projecting from the outer sides of the long wall inner surface forming portions 4 and 4 are inserted into the respective insertion ports 6 at the middle.

  On both short sides of the bottom wall 1, support walls 14a are provided for hooking the upper edge of the short side of the pack container. Therefore, the short wall outer surface forming portions 10 and 10 are provided continuously on both short sides of the bottom wall 1, and the folded piece forming portions 11 and 12 are extended on both sides thereof. The length (left and right direction) of the folded piece forming portions 11 and 12 is set to about one half of the length of the long wall outer surface forming portions 2 and 2, and the width (vertical direction) is the short wall outer surface. It is about twice as large as the forming portions 10 and 10, and folding lines 13 and 13 are engraved in the middle lateral direction.

  The support wall forming portions 14 and 14 are passed between the outward extending portions of the folding piece forming portions 11 and 12 (outside the folding curves 13 and 13). Folding curves 28 and 28 are engraved on both sides of the support wall forming portions 14 and 14, and the support wall forming portions 14 and 14 and the short wall outer surface forming portions 10 and 10 are separated from each other. Punching holes 15 and 15 are provided. The width of the support wall forming portions 14 and 14, in other words, the height of the support wall 14 a is determined by the vertical width of the punched holes 15 and 15. In other words, the width of the support wall forming portions 14 and 14 is determined by the pack container to be stored. It needs to be set to be a little larger than the height of.

  A vertical partition forming portion 16 and a horizontal partition forming portion 17 for forming the cross-shaped partition B are connected to the outside of one long wall inner surface forming portion 4 so as to be cut off. These vertical partition forming part 16 and horizontal partition forming part 17 are separated during assembly (see FIG. 2).

  The vertical partition forming portion 16 has cuts 18 and 19 formed at both ends and two central portions, and is used as the vertical partition 26 as it is. The horizontal partition forming part 17 has parallel folding lines 20 and 21 each having a predetermined width that are cut short at both ends and the central part, and extends in the central length direction to form a parallel folding line 20 and a parallel folding line 21. A subsequent cut line 22 is entered.

  In the lateral partition forming part 17, when both sides are bent at right angles along the parallel folding lines 20, 21, the connecting surfaces between the parallel folding curves 20, 20 at both ends and between the parallel folding curves 21, 21 at the central part, respectively. 23 and 24 remain, and a transverse partition 25 having an inverted U-shaped cross section with the connecting surfaces 23 and 24 as the upper surface is assembled (see FIG. 3). Both side plates of the horizontal partition 25 serve as support walls 17a for hooking one short side of the pack container on the upper end surface. The vertical partition 26 is assembled by engaging the notches 19 and 19 at the center thereof from above with a slit 28 formed from the connecting surface 24 of the horizontal partition 25 to the support wall 17a, thereby forming a cross-shaped partition B.

  In order to fold the mount and assemble the container A, first, the upper and lower folded piece forming portions 11 and 12 are folded in two from the folding lines 13 and 13 respectively (see FIG. 4). At that time, the support wall forming portions 14 and 14 are also turned over to overlap the short wall outer surface forming portions 10 and 10. Next, the folded folded piece forming portions 11, 12 are bent at right angles from the folding lines 31, 31a, 32, 32a to form folded pieces 11a, 12a, and further, the short wall outer surface forming portions 10, 10 are formed. Is bent from the fold lines 33 and 33 and raised at right angles to form the short walls 10a and 10a (FIG. 5).

  As the folding pieces 11 a and 12 a are bent, the support wall forming portions 14 and 14 are separated from the short wall outer surface forming portion 10. That is, since the folding lines 31 and 32 and the folding lines 31a and 32a are engraved on the same line as shown in FIG. 1, the folding lines 31a and 32a on the inner side are bent due to the thickness of the cardboard when they are folded over. The support wall forming portions 14 and 14 between them receive a compressive force from both sides (see FIG. 9). However, since the folding lines 28 and 28 are engraved on both sides of the support wall forming portions 14 and 14, the compressive force is generated by the support wall forming portions 14 and 14 being bent from the folding curves 28 and 28. I can escape. As a result, the support wall forming portions 14 and 14 are lifted and separated from the short wall outer surface forming portions 10 and 10.

  As described above, the short wall outer surface forming portions 10 and 10 are bent from the folding lines 33 and 33 to stand, thereby forming the short walls 10a and 10a on the outer side, and at the same time, the supporting walls 14a and 10a on the inner side. 14a is configured. At that time, since the folding pieces 11a and 11a (12a and 12a) on both sides are positioned on the folding lines 5 and 5, respectively (see FIG. 5), each folding piece is folded into the long wall outer surface forming portions 2 and 2. While bending from the curves 5 and 5, the long wall inner side surface forming portions 4 and 4 are folded along the frame forming portions 3 and 3 so as to enclose each of the folding pieces 11a and 12a. Long walls 4a and 4a are formed (see FIGS. 6 and 7). At that time, each insertion protrusion 8 is inserted into the corresponding insertion port 6.

  After the container A is assembled in this way, the cross-shaped partition B is inserted into the container A, and the intermediate portions of the support walls 14a and 14a are fitted into the notches 18 and 18 of the vertical partition 26, thereby completing the assembly (see FIG. 8).

  Thus, the corrugated cardboard case according to the present invention has a simple process of simultaneously raising the short wall 10a and the support wall 14a, a process of constructing the long wall 4a while folding the folding pieces 11a and 12a, and an assembling process of the cross-shaped partition B. In addition, it is possible to assemble easily and quickly by a simple method.

  In the assembled cardboard case, the support walls 14a and 14a are fixed from both sides, and the central part is held by the vertical partition 26, so that it is firm without swinging. Further, since the horizontal partition 25 is formed in an inverted U shape via the connecting surfaces 23 and 24 and is held by the vertical partition 26, it is also firm without swinging. Thus, the stored pack container 40 is securely hooked and supported over its entire length by the upper edge of the short side being inserted into the concave portion of the support wall 14a and the support wall 17a of the horizontal partition 25. Therefore, the pack container 40 maintains a stable suspended state in the cardboard case.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
