Description

  The present invention relates to a partition member, and more particularly, to a partition member used for a storage box provided with a flap that is foldable and formed at at least one of an upper edge portion or a lower edge portion of one side surface.

  Conventionally, when a product is transported, a method of storing and transporting the product in a box-shaped storage box formed of cardboard or the like is generally used. When products are stored in a storage box, only one product may be stored in one cardboard, but a plurality of products may be stored in one cardboard.

  For example, it corresponds to the case where the product main body and accessories are stored in one cardboard, and the case where a product set consisting of a plurality of products such as tableware is stored in one cardboard.

  In this way, when storing multiple products in one cardboard, a partition member is installed in the storage box to prevent contact between the products and prevent the products from being damaged or damaged. Often to do.

  When installing the partition member, if the installed partition member easily moves or falls within the storage box, the stored products may come into contact with each other and cause damage or the like. For this reason, the partition member needs to be fixed so as not to move or tilt in the storage box.

As a method for fixing the partition member, for example, a method for firmly adhering the side end portion of the partition member to the side wall of the storage box (see, for example, Patent Document 1) has been proposed.
JP 2000-128150 A

  However, as described above, in the method of firmly adhering the side end portion of the partition member to the side wall of the storage box, there is a problem that the operation of adhering the partition member is complicated and the work load is heavy.

  Furthermore, even when the storage box is partitioned by the partition member, it is necessary to install a cushioning material or the like corresponding to the partitioned storage space, resulting in a problem that a large amount of packing material is required. It was.

  This invention is made | formed in view of the said problem, and makes it a subject to provide the partition member which can be easily installed in a storage box and can aim at reduction of the material to be used.

  In order to solve the above problem, the partition member according to the present invention is a partition member used for a storage box provided with a flap that is formed to be foldable at least one of an upper edge portion or a lower edge portion of one side surface. A standing wall portion that stands up against the one side surface, the side wall surface of the one side surface being in contact with a free end portion of the flap, and an end edge portion of the standing wall portion is opposite to the one side surface. It has the extending | stretching part extended and formed in the side surface direction, and inscribed in the other side surface side of the said storage box, It is characterized by the above-mentioned.

  According to the partition member according to the present invention, movement and tilting of the partition member in the direction of the one side wall surface are restricted by the one side wall surface of the standing wall portion coming into contact with the free end portion of the flap. In addition, since the extending portion of the partition member is extended and inscribed on the other side of the storage box, the movement of the partition member in the direction of the other side of the storage box is restricted. Therefore, by using the partition member configured in this way for the storage box, it is possible to restrict the partition member from easily moving in the box, and the standing wall portion of the partition member can be easily tilted. Can be prevented.

  Moreover, since the extending portion is formed by extending the end portion of the standing wall portion, the extending portion and the standing wall portion can be configured by, for example, a bendable plate-like member. For this reason, while being able to reduce the number of members, such as a partition member, the structure can be made into a simple structure.

  Furthermore, since the internal space of the storage box can be divided using the partition member, different stored items can be stored efficiently without causing interference.

  In addition, the partition member is configured to cushion the stored item stored between the upright wall portion and the other side surface by bending the extended portion formed to be extended according to the outer shape of the stored item. May be included.

  In this way, by forming the buffering means for the stored items by bending the extending portion, the partition member and the buffering means can be shared, so the number of members such as the buffering means can be reduced. It becomes possible to realize cost reduction.

  Further, since the partition member also serves as the buffering means, the number of constituent members can be reduced as compared with the case where the partition member and the buffer means are provided separately, so that it is possible to reduce the work load during the storing operation. .

  In addition, since the buffer means is formed by bending the stretched part, the bent shape can be changed according to the outer shape of the product, and a wide variety of buffer material shapes can be easily configured. It becomes.

  Moreover, the partition member mentioned above may have a top surface protection part that is formed to extend sideways along the ceiling surface of the storage box while the upper end edge of the standing wall part is bent.

  Thus, even when the partition member has the top surface protection portion and the tape material or the like is adhered to the pair of flaps forming the top surface of the storage box, the box is opened. The top surface protection part can prevent the tip of a blade or the like that has sometimes broken the tape material from entering the inside of the storage box. For this reason, the goods etc. which are stored in a storage box can be protected by a top surface protection part, and it can prevent that goods etc. are damaged.

  In the case of using the partition member according to the present invention, the position in the storage box is easily fixed by bringing the flap into contact with the standing wall portion and further bringing the end of the extending portion into contact with the other side surface of the storage box. Therefore, it is possible to easily install the partition member.

  Hereinafter, the partition member concerning the present invention is explained in detail using a drawing.

[Embodiment 1]
FIG. 1 is a perspective view showing a partition member according to Embodiment 1 and a storage box in which the partition member is stored.

  The storage box 1 is made of cardboard. The storage box 1 is a flap that can be bent by cutting the upper and lower ends along the corners of the rectangular cylinder after forming a rectangular cylinder whose upper and lower sides are opened by joining the ends of the cardboard. And each flap is bent at a right angle in a state where a certain height is secured.

  In FIG. 1, it forms in the 1st flap 2 provided with short side width L1 among the flaps formed in the lower edge part of a bottom face side, and the upper edge part of the top | upper surface side located above the 1st flap 2. In FIG. A second flap 3, a third flap 4 having a short piece width L <b> 1 that is also formed on the upper edge of the top surface side, and a fourth flap 5 and a fifth flap 6 having a long piece width are shown. In addition, the side wall surface 7a of the storage box 1 in which the 1st flap 2 is provided in a lower edge part, and the 2nd flap 3 is provided in an upper edge part corresponds to one side which concerns on this invention, and is the other side of a storage box. The side wall surface 7b corresponds to the other side surface according to the present invention.

  As shown in FIG. 2 (a), the partition member 8 is a strip-shaped dupole piece having a width substantially equal to or slightly shorter than the short side width L1 of the first flap 2, the second flap 3, and the third flap 4. It is constituted by. The partition member 8 is assembled into the shape shown in FIG. 1 by folding the dotted line portion A and the dotted line portion B of the corrugated cardboard piece shown in FIG. 2A into mountain folds and folding the dotted line portion C into valley folds. Here, the corrugated cardboard piece part between the dotted line part A and the dotted line part B constitutes a standing wall part 9 constituting the boundary wall of the storage space in the storage box 1, and the end of the corrugated cardboard piece bent by the dotted line part C The part portion constitutes the extending portion 10.

  FIG. 2B is a side sectional view showing a state in which the partition member 8 bent with respect to the storage box 1 is stored. When the partition member 8 is stored in the storage box 1, as shown in FIG. 2B, a dotted line portion is formed below the first flap 2 formed on the lower edge portion of the side wall surface 7 a of the storage box 1. The lower folded portion 11 formed by bending B and the dotted line portion C is caused to enter, and the free end portion of the first flap 2 is brought into contact with the side wall surface of the standing wall portion 9. In this case, since the first flap 2 is formed of a cardboard material in which the lower edge portion of the side wall surface 7a of the storage box 1 is bent, the bent first flap 2 is oriented in the bottom direction due to the rigidity of the cardboard material. There is a tendency to have the power to go back.

  Therefore, the lower folded portion 11 that has entered the lower side of the first flap 2 is in a state of being urged by the first flap 2, and the free end portion of the first flap 2 is also on the side wall surface of the standing wall portion 9. Since the pressing force is applied downward in the contacted state, the partition member 8 is moved in the first flap 2 side direction by the first flap 2 that is in contact with the standing wall 9. Can be regulated.

  On the other hand, the dimensions of the extending portion 10 on the end portion side are such that the end portion 10a of the extending portion 10 is the third flap 4 in a state where the tip of the first flap 2 is in contact with the side wall surface of the standing wall portion 9. Is defined in advance to a length that abuts against the lower edge of the side wall surface 7b. For this reason, when the edge part 10a of this extending | stretching part 10 inscribes the side wall surface 7b by the side of the 3rd flap 4, the movement to the side wall surface 7b direction in the partition member 8 is controlled.

  Further, since the width dimension of the partition member 8 is defined to be substantially the same width or slightly shorter than the short side width L1 of the first flap 2, etc., in the state where the partition member 8 is stored in the storage box 1, The side wall surface on which the fourth flap 5 is provided and the side wall surface on which the fifth flap 6 is provided come into contact with both side ends of the partition member 8, and movement in the width direction is restricted.

  Next, after the second flap 3 is bent to the inside of the storage box 1, the upper folded portion formed by bending the dotted line portion A so as to cover the free end portion of the second flap 3 from above. 12, the top flap is closed by closing the fourth flap 5 and the fifth flap 6 from above.

  As described above, by arranging the second flap 3 below the upper turn-back portion 12, the free end portion of the second flap 3 tends to rise in the direction of the top surface in the same manner as the first flap 2. The upper folded portion 12 located on the upper side of the second flap 3 is biased by the second flap 3. Further, in the same manner as the first flap 2, in order to apply a pressing force upward in a state where the free end portion of the second flap 3 is in contact with the side wall surface of the standing wall portion 9, it is brought into contact with the standing wall portion 9. The second flap 3 can restrict the upper part of the partition member 8 from tilting toward the side wall surface 7a.

  Thus, by installing the partition member 8 in the storage box 1, the internal space of the storage box 1 can be divided into the space S <b> 1 and the space S <b> 2 by the standing wall portion 9 of the partition member 8. In addition, the movement of the partition member 8 is restricted by the contact of the first flap 2 with the upright wall portion 9 and the inscribed contact with the side wall surface 7b by the end portion 10a of the extending portion 10, and the second flap 3 Since the tilting of the standing wall 9 is restricted by the contact with the standing wall 9, the position of the partition member 8 can be fixed without adhesively fixing the side end of the standing wall 9 to the inner wall of the storage box 1. Can be done.

  In the partition member 8 described above, the end portion 10a of the extending portion 10 is directly inscribed in the side wall surface 7b. However, another member (not shown) is provided between the end portion 10a of the extending portion 10 and the side wall surface 7b. It is good also as a structure which provides and regulates the movement of the partition member 8. FIG. For example, as an example of another member, by using a flap provided on the other side wall surface 7b side, the end portion 10a of the extending portion 10 may be inscribed in the side wall surface 7b side via the flap. Good.

  Furthermore, since the partition member 8 is constituted by a single piece of cardboard piece having a band shape, that is, by one member, it is not necessary to combine (assemble) a plurality of cardboard pieces as in the conventional partition member. Therefore, it is possible to simplify the assembly work and reduce the number of components.

  Further, since one side surface of the standing wall portion 9 of the partition member 8 is supported by the first flap 2 and the second flap 3, the partition member 8 has a dimension width sufficient to contact all the side surfaces of the storage box 1. There is no need to ensure the amount, and the amount of the material constituting the partition member 8 can be reduced as compared with the prior art.

  In the first embodiment, the case where the standing wall portion 9 and the extending portion 10 of the partition member 8 are configured by a single cardboard piece, that is, a single member has been described. However, the standing wall portion 9 and the extending portion 10 are extended. The part 10 is not necessarily limited to one constituted by one member.

  For example, as in the partition member 13 shown in FIG. 3A, the standing wall portion 14 and the extending portion 15 are formed by separate members, and the protruding edge portion 16 is provided at the lower edge portion of the standing wall portion, and the protruding portion A structure in which a slit-like engagement hole 17 that engages with the edge 16 is formed at the end of the extending portion 15 may be employed.

  Even when the partition member 13 is formed in this manner, as shown in FIG. 3B, the internal space of the storage box 1 is divided into the space S <b> 1 and the space S <b> 2 by the standing wall portion 14 of the partition member 13. It becomes possible to divide. Further, the movement of the partition member 13 is restricted by the contact of the first flap 2 with the standing wall portion 14 and the inscribed contact with the side wall surface 7b by the end portion 15a of the extending portion 15. Further, since the tilting of the standing wall portion 14 is restricted by the contact of the second flap 3 with the standing wall portion 14, the position of the partition member 8 can be fixed.

  Further, in the partition member 13 shown in FIG. 3, the end 15a of the extending portion 15 is directly inscribed in the side wall surface 7b. However, another not shown is provided between the end 15a of the extending portion 15 and the side wall surface 7b. It is good also as a structure which regulates the movement of the partition member 13 by providing this member. For example, as an example of another member, by using a flap provided on the other side wall surface 7b side, the end portion 15a of the extending portion 15 may be inscribed on the side wall surface 7b side via the flap. Good.

It has a function as a material. In the partition member 20 shown in FIG. 4, the end portion above the dotted line portion A is a portion that constitutes the above-described upper folded portion 12, and the portion sandwiched between the dotted line portion A and the dotted line portion B is a standing wall portion. 9 is a part that constitutes 9. Further, the lower folded portion 11 is formed by bending the dotted line portion B and the dotted line portion C.

  In addition, a strip-shaped (horizontal U-shaped) notch with the dotted line portion A as an end is formed in the center of the standing wall portion 9, and the strip-shaped portion 21 is formed by bending the dotted line portion A. It is more upright and has a structure in which the upper folded portion 12 and a horizontal top surface protection material (top surface protection portion) are formed. Further, an annular hole 22 corresponding to the pipe diameter of the cylindrical duct of the ventilation grill is formed in the center of the standing wall portion 9, and the side edge of the annular hole 22 is cut out in a rectangular shape (see FIG. 4). The shaded portion shown indicates the cut-out portion.)

  The portion below the dotted line portion C constitutes the stretched portion already described, but the stretched end portion of the stretched portion 23 is further stretched as compared to the first embodiment, A locking projection 24 is formed. A plurality of folding lines (dotted line part a, dotted line part b, dotted line parts c1 to c3, dotted line part d, dotted line part e1, and dotted line part e2) are formed in the extending part 23 and stored in the storage box 1. Guide characters 29 (A (mountain), B (mountain), C (valley), a (valley), b (valley), c1 (shown in FIG. 4) (Valley), c2 (valley), c3 (valley), d (valley), e1 (valley), e2 (mountain)) are printed on the surface of the cardboard piece.

  Further, the extending portion 23 is formed with a substantially H-shaped cut portion 26 in which the locking protrusion 25 is cut out. Further, in the portion of the extending portion 23 near the standing wall portion 9, two locking holes 27, 28 for maintaining the bent state of the extending portion 23 that is locked by the locking protrusions 24, 25 and bent are provided.
