Description

本発明は、電子機器を梱包箱に梱包するときに、前記電子機器の角部と前記ダンボール箱との隙間に挿入される緩衝用梱包材に関するものである。   The present invention relates to a cushioning packing material that is inserted into a gap between a corner of the electronic device and the cardboard box when the electronic device is packed in a packing box.

従来、電子機器はダンボール箱等の梱包用箱に梱包されて、搬送される。前記電子機器をダンボール箱に梱包するときには、前記ダンボール箱と前記電子機器との隙間に緩衝用梱包材が挿入される。前記緩衝用梱包材は前記電子機器が梱包されたダンボール箱が落下したり、他のものと接触したりして前記ダンボール箱に衝撃が加えられたときに、その衝撃が前記電子機器に伝達されないように吸収する部材である。前記緩衝梱包材として、緩衝能力及び強度の高さ、加工性のよさ、軽量である点で優れているという理由から発泡樹脂の成型体が広く採用されている。また、前記緩衝用梱包材は前記電子機器の４隅に取り付けられることが多い。このように、前記緩衝用梱包材を配置することで、十分な緩衝能力を発揮することができるとともに、使用量を少なくすることができる。   Conventionally, electronic devices are packed in a packing box such as a cardboard box and transported. When packing the electronic device in a cardboard box, a cushioning packing material is inserted into the gap between the cardboard box and the electronic device. The shock-absorbing packing material is not transmitted to the electronic device when the cardboard box in which the electronic device is packaged falls or comes into contact with another object and an impact is applied to the cardboard box. It is a member to absorb. As the buffer packaging material, a foamed resin molded body is widely used because of its superior buffer capacity, high strength, good workability, and light weight. Further, the cushioning packing material is often attached to the four corners of the electronic device. Thus, by arranging the buffer packaging material, it is possible to exhibit a sufficient buffer capacity and reduce the amount of use.

図８は従来の緩衝用梱包材を含む緩衝用梱包材ユニットの正面図であり、図９は図８に示す緩衝用梱包材ユニット分割させた状態の正面図である。図８に示すように１つの金型を用いて４個の緩衝用梱包材９２、９３、９４、９５が一体的に形成された緩衝用梱包材ユニット９１が製造される。   FIG. 8 is a front view of a cushioning packing material unit including a conventional cushioning packing material, and FIG. 9 is a front view of the buffering packing material unit shown in FIG. As shown in FIG. 8, a shock-absorbing packing material unit 91 in which four shock-absorbing packing materials 92, 93, 94, 95 are integrally formed is manufactured using a single mold.

図８に示すように緩衝用梱包材ユニット９１において、緩衝用梱包材９２と緩衝用梱包材９３とは連結部９１１、９１２で、緩衝用梱包材９３と緩衝用梱包材９４とは連結部９１３で、緩衝用梱包材９４と緩衝用梱包材９５とは連結部９１４、９１５でそれぞれ一体的に連結されている。   As shown in FIG. 8, in the buffer packaging material unit 91, the buffer packaging material 92 and the buffer packaging material 93 are connected portions 911 and 912, and the buffer packaging material 93 and the buffer packaging material 94 are connected portions 913. Thus, the cushioning packing material 94 and the cushioning packaging material 95 are integrally connected by connecting portions 914 and 915, respectively.

図９に示すように、連結部９１１、９１２、９１３、９１４、９１５にはそれぞれ、中央部に弱所が形成されており、緩衝用梱包材ユニット９１を連結部９１１〜９１５で分割することで、緩衝用梱包材９２〜９５が形成される。分割された緩衝用梱包材９２〜９５にはそれぞれ、連結部９１１〜９１５が凸部９１１ａ〜９１５ａ、９１１ｂ〜９１５ｂとなって残留される。   As shown in FIG. 9, each of the connecting portions 911, 912, 913, 914, and 915 has a weak portion at the center, and the buffer packaging unit 91 is divided by the connecting portions 911 to 915. The buffer packing materials 92 to 95 are formed. In the divided cushioning packing materials 92 to 95, the connecting portions 911 to 915 remain as convex portions 911a to 915a and 911b to 915b, respectively.

図１０は従来の緩衝用梱包材、電子機器を梱包箱に収納したときの平面図である。図１０に示すように緩衝用梱包材９２、９３、９４、９５は、電子機器９６の４隅にそれぞれ装着された後、梱包箱（ここでは段ボール箱９７）の内部に収納される。   FIG. 10 is a plan view when a conventional cushioning packing material and electronic device are stored in a packing box. As shown in FIG. 10, the shock-absorbing packing materials 92, 93, 94, and 95 are mounted in the four corners of the electronic device 96 and then stored in a packing box (here, a cardboard box 97).

このように緩衝用梱包材９２、９３、９４、９５を電子機器９６に取り付けた状態で、ダンボール箱９７に収納することで、段ボール箱９７に衝撃が加えられた場合であっても、緩衝用梱包材９２、９３、９４、９５にて衝撃が緩衝され電子機器９６が守られる。   Even when an impact is applied to the cardboard box 97 by storing the cushioning packing materials 92, 93, 94, and 95 in the cardboard box 97 in a state of being attached to the electronic device 96, The shock is buffered by the packing materials 92, 93, 94, and 95 to protect the electronic device 96.

図１０に示しているように、緩衝用梱包材９３、９４の凸部９１３ｂ、９１３ａはダンボール箱９７の側面部９７１と当接するように配置される。このことにより、段ボール箱９７の側面部９７１が押されて外側に膨らんでしまい、側面部９７１の膨らんだ部分の外部がこすれて印刷がはがれてしまったり、コンテナ等の搬送具への積載時の密接度が低下し、積載量が減ってしまったりする。   As shown in FIG. 10, the convex portions 913 b and 913 a of the cushioning packing materials 93 and 94 are disposed so as to contact the side surface portion 971 of the cardboard box 97. As a result, the side surface portion 971 of the cardboard box 97 is pushed and bulges outward, the outside of the bulged portion of the side surface portion 971 is rubbed off, and the print is peeled off. The closeness decreases and the loading capacity decreases.

そこで、実用新案登録第３１２８４０９号公報に記載の考案では、緩衝用梱包材の凸部の裏側の部分に切り込みを形成し、切り込み部で変形して、凸部が切り込み部側に入り込むことで、梱包箱が膨らむのを防いでいる。
実用新案登録第３１２８４０９号公報 Therefore, in the invention described in Utility Model Registration No. 3128409, by forming a cut in the back side portion of the convex portion of the cushioning packing material, deforming at the cut portion, the convex portion enters the cut portion side, The packing box is prevented from expanding.
Utility Model Registration No. 3128409

しかしながら、緩衝用梱包材ユニット９１を分割するときに、連結部９１３の割れ具合がばらつき、凸部が緩衝用梱包材９３或いは９４の一方のみに残り、他方には凸部が形成されない場合がある。このように、一方にのみ形成された凸部はその突出量が多くなるので、切り込み部で変形するだけでは、十分に入り込むことができない場合があり、側面部の膨らんだ部分の外部がこすれて印刷がはがれてしまったり、コンテナ等の搬送具への積載時の密接度が低下し、制裁量が減ってしまったりする不具合を解決できない場合がある。   However, when the cushioning packaging unit 91 is divided, the degree of cracking of the connecting portion 913 varies, and the convex portion may remain only on one of the cushioning packaging materials 93 or 94, and the convex portion may not be formed on the other. . As described above, since the protruding portion formed only on one side has a large amount of protrusion, it may not be able to sufficiently enter only by deforming at the cut portion, and the outside of the bulging portion of the side surface portion is rubbed. In some cases, it may not be possible to solve the problem that the print is peeled off, the closeness when the container or the like is loaded on the carrier, and the amount of sanctions is reduced.

そこで本発明は、緩衝用梱包材が取り付けられた電子機器を梱包箱に収納したときに、前記緩衝用梱包箱に形成された凸部によって、前記梱包箱が膨らむのを抑制し、前記梱包箱の外装が削れたり、積載量が減ったりするのを抑えることを目的とする。   Therefore, the present invention suppresses the expansion of the packing box by the convex portion formed in the buffering packing box when the electronic device to which the buffering packing material is attached is stored in the packing box, and the packing box The purpose is to prevent the exterior of the machine from being scraped or the load being reduced.

上記目的を達成するため本発明は、１つの金型に発泡性樹脂を充填して一列に並ぶように一体的に形成し、隣り合うもの同士を連結する連結部で４個に分割することで形成され、搬送時に梱包箱に収納される電子機器の角部周辺を覆うように装着され、前記梱包箱と前記電子機器との間に配置されて、前記電子機器への衝撃を緩衝する緩衝用梱包材において、分割前に中央部に位置された２個の緩衝用梱包材の少なくとも一方には、前記２個の緩衝用梱包材を連結した連結部が分割時に残留することで形成された直方体形状の凸部が備えられており、前記２個の緩衝用梱包材は、いずれも、内部に前記凸部に近接し、前記凸部と平行に形成された第１凹孔と、前記第１凹孔の中央部と接続し前記第１凹孔と直交するとともに、前記凸部と反対側に延伸して形成された第２凹孔とを有するＴ字状の凹孔を有しており、前記第１凹孔の長手方向の長さが前記凸部の長手方向の長さよりも長く、前記第１凹孔の深さが前記凸部の短手方向の長さよりも深くなるように形成されていることを特徴とする。   In order to achieve the above-mentioned object, the present invention can be obtained by filling a mold with a foamable resin and integrally forming it in a row and dividing it into four parts by connecting portions that connect adjacent ones. A buffer that is formed so as to cover the periphery of the corner of the electronic device that is housed in the packaging box during transportation, and is arranged between the packaging box and the electronic device to buffer the impact on the electronic device. In the packing material, a rectangular parallelepiped formed by connecting at least one of the two cushioning packing materials positioned in the central portion before the division with a connecting portion connecting the two cushioning packing materials remaining at the time of the division. A convex portion having a shape is provided, and each of the two cushioning packing materials is close to the convex portion inside and has a first concave hole formed in parallel with the convex portion, and the first Connected to the central part of the concave hole and orthogonal to the first concave hole, opposite to the convex part Having a T-shaped concave hole having a second concave hole formed by extending the first concave hole, the length of the first concave hole in the longitudinal direction being longer than the length of the convex portion in the longitudinal direction, The depth of the first concave hole is formed so as to be deeper than the length of the convex portion in the short direction.

この構成によると、前記凸部が前記第１凹孔に押し込まれるように形成されているので、梱包箱が膨らむのを抑制することができる。   According to this structure, since the said convex part is formed so that it may be pushed in into the said 1st recessed hole, it can suppress that a packaging box swells.

これにより、前記梱包箱がこすれて前記梱包箱の外装が剥がれてしまったり、積載量が減ってしまったりする不具合を抑制することができる。   Thereby, the malfunction that the said packaging box is rubbed and the exterior of the said packaging box peels off, or a load amount reduces can be suppressed.

上記構成において、前記第１凹孔は長手方向の両端部が前記凸部長手方向の両端部よりも外側に伸びて形成されているものであってもよい。   The said structure WHEREIN: The said 1st recessed hole may be formed so that the both ends of a longitudinal direction may extend outside the both ends of the said convex part longitudinal direction.

上記構成において、前記第１凹孔の第２凹孔と反対側の壁面は、開口部に向かって拡がるように傾斜した傾斜面を有するものであってもよい。   The said structure WHEREIN: The wall surface on the opposite side to the 2nd recessed hole of a said 1st recessed hole may have an inclined surface inclined so that it might expand toward an opening part.

上記構成において、前記電子機器は直方体形状であり、前記電子機器の四隅を覆うように装着されるものであってもよい。   In the above configuration, the electronic device may have a rectangular parallelepiped shape and may be mounted so as to cover four corners of the electronic device.

本発明によると、緩衝用梱包材が取り付けられた電子機器を梱包箱に収納したときに、前記緩衝用梱包箱に形成された凸部によって、前記梱包箱が膨らむのを抑制し、前記梱包箱の外装が削れたり、積載量が減ったりするのを抑えることができる。   According to the present invention, when the electronic device to which the buffering packing material is attached is stored in the packing box, the protruding box formed on the buffering packing box prevents the packing box from expanding, and the packing box It is possible to prevent the exterior of the machine from being shaved and the load from being reduced.

以下に本発明の実施形態を図面を参照して説明する。図１は本発明にかかる緩衝用梱包材の製造直後の状態である緩衝用梱包材ユニットの正面図であり、図２は図１に示す緩衝用梱包材ユニットから分解された緩衝用梱包材の正面図であり、図３は本発明にかかる緩衝用梱包材を電子機器の一例であるＤＶＤレコーダに装着する状態の平面図である。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a shock-absorbing packing material unit in a state immediately after the production of the shock-absorbing packing material according to the present invention, and FIG. 2 is a view of the shock-absorbing packing material disassembled from the shock-absorbing packing material unit shown in FIG. 3 is a front view, and FIG. 3 is a plan view showing a state in which the cushioning packing material according to the present invention is mounted on a DVD recorder which is an example of an electronic apparatus.

図１に示すように緩衝用梱包材ユニット１は４個の緩衝用梱包材２、３、４、５が一体的に連結された形状を有するものである。緩衝用梱包材２と緩衝用梱包材と３は連結部１１、１２を介して、緩衝用梱包材３と緩衝用梱包材４とは連結部１３を介して、緩衝用梱包材４と緩衝用梱包材５は連結部１４、１５を介してれそれぞれ一体的に連結されている。   As shown in FIG. 1, the cushioning packaging material unit 1 has a shape in which four cushioning packaging materials 2, 3, 4, 5 are integrally connected. The shock-absorbing packing material 2 and the shock-absorbing packing material 3 are connected to the shock-absorbing packing material 4 and the shock-absorbing packing material 4 via the connecting portion 13. The packing material 5 is integrally connected via the connecting portions 14 and 15.

緩衝用梱包材ユニット１は発泡スチロール等の発泡樹脂の一体成型で製造されるものであり、金型に緩衝用梱包材２または緩衝用梱包材５のいずれか一方側より、発泡樹脂を注入させることで形成されるものであり、連結部１１〜１５は発泡性樹脂が隣り合う緩衝用梱包材を形成する金型に流入するときの流入口に充填された発泡樹脂が固化したものである。   The shock-absorbing packing material unit 1 is manufactured by integral molding of a foamed resin such as polystyrene foam, and foam resin is injected into the mold from either the shock-absorbing packing material 2 or the shock-absorbing packing material 5. The connecting portions 11 to 15 are formed by solidifying the foamed resin filled in the inflow port when the foamable resin flows into the mold forming the adjacent cushioning packing material.

図２に示すように、緩衝用梱包材ユニット１は連結部１１、１２、１３、１４、１５を割ることで、緩衝用梱包材２、３、４、５に分割することが可能である。通常は、図２に示すように連結部１１、１２は緩衝用梱包材２に凸部１１ｂ、１２ｂとして、連結部１１、１２、１３は緩衝用梱包材３に凸部１１ａ、１２ａ、１３ａとして、連結部１３、１４、１５は緩衝用梱包材４に凸部１３ｂ、１４ｂ、１５ｂとして、連結部１４、１５は緩衝用梱包材５に凸部１４ａ、１５ａとしてそれぞれ、残留される。   As shown in FIG. 2, the buffer packaging material unit 1 can be divided into buffer packaging materials 2, 3, 4, and 5 by dividing the connecting portions 11, 12, 13, 14, and 15. Usually, as shown in FIG. 2, the connecting portions 11 and 12 are provided as convex portions 11 b and 12 b on the cushioning packing material 2, and the connecting portions 11, 12 and 13 are provided as convex portions 11 a, 12 a and 13 a on the cushioning packing material 3. The connecting portions 13, 14, and 15 are left as convex portions 13 b, 14 b, and 15 b on the cushioning packing material 4, and the connecting portions 14 and 15 are left as convex portions 14 a and 15 a on the buffering packing material 5.

図３に示すようにＤＶＤレコーダ６を梱包箱（ここでは段ボール箱７）に収納するときには、ＤＶＤレコーダ６の４隅に緩衝用梱包材２、３、４、５が取り付けられる。緩衝用梱包材２はＤＶＤレコーダ６の左前の角部に装着され、緩衝用梱包材３はＤＶＤレコーダ６の左後ろの角部に装着され、緩衝用梱包材４はＤＶＤレコーダ６の右後ろ角部に装着され、緩衝用梱包材５は右前の角部に装着される。   As shown in FIG. 3, when the DVD recorder 6 is stored in a packaging box (here, a cardboard box 7), cushioning packing materials 2, 3, 4, and 5 are attached to the four corners of the DVD recorder 6. The buffer packing material 2 is mounted on the left front corner of the DVD recorder 6, the buffer packing material 3 is mounted on the left rear corner of the DVD recorder 6, and the buffer packing material 4 is mounted on the right rear corner of the DVD recorder 6. The cushioning packing material 5 is attached to the right front corner.

４つの角部にそれぞれ緩衝用梱包材２、３、４、５が取り付けられたＤＶＤレコーダ６は段ボール箱７の内部に収納される。このとき、緩衝用梱包箱３、４の凸部１３ａ、１３ｂは段ボール箱７の側壁部７１と当接するものである。   The DVD recorder 6 having the cushioning packing materials 2, 3, 4, and 5 attached to the four corners is housed in a cardboard box 7. At this time, the convex portions 13 a and 13 b of the buffer packaging boxes 3 and 4 come into contact with the side wall portion 71 of the cardboard box 7.

また、図４は図１に示す緩衝用梱包材ユニットの中央の２個の緩衝用梱包材を分割したときの正面図であり、図５は図４の示す緩衝用梱包材の平面図である。図４、図５に示すように、緩衝用梱包材ユニット１を分割するときに、連結部１３の割れ方にばらつきが発生することがある。図４に示すように、連結部１３が一方の緩衝用梱包材（図４、図５においては緩衝用梱包材４０）との境界で分割され、他方の緩衝用梱包材（図４、図５においては緩衝用梱包材３０）にのみ凸部１３ｃが形成される場合がある。   4 is a front view when the two cushioning packing materials at the center of the cushioning packaging unit shown in FIG. 1 are divided, and FIG. 5 is a plan view of the cushioning packaging material shown in FIG. . As shown in FIGS. 4 and 5, when the cushioning packaging unit 1 is divided, variations may occur in how the connecting portion 13 is cracked. As shown in FIG. 4, the connecting portion 13 is divided at the boundary with one buffer packing material (the buffer packing material 40 in FIGS. 4 and 5), and the other buffer packing material (FIGS. 4 and 5). The convex portion 13c may be formed only on the cushioning packing material 30).

このように、凸部１３ｃが形成された緩衝用梱包材３０をＤＶＤレコーダ６の角部に取り付けて、段ボール箱７に収納すると、段ボール箱７の側壁部７１が大きく膨らんでしまう。   As described above, when the cushioning packing material 30 formed with the convex portion 13c is attached to the corner portion of the DVD recorder 6 and stored in the cardboard box 7, the side wall 71 of the cardboard box 7 swells greatly.

そこで、緩衝用梱包材３（３０）には、断面Ｔ字状の凹孔３１が形成されている。凹孔３１は、凸部１３ｃに平衡に形成された第１凹孔部３１１と第１凹孔部３１１の凸部１３ｃと反対側の面より直交するように形成された第２凹孔部３１２とを有している。第１凹孔部３１１は凸部１３ｃの長手方向の長さよりも長くなるように形成されている。また、第１凹孔部３１１は、凸部１３ｃの長手方向の両端部よりも外側に到達するように形成されている。   Therefore, a concave hole 31 having a T-shaped cross section is formed in the cushioning packing material 3 (30). The concave hole 31 is formed so as to be orthogonal to the first concave hole portion 311 formed in equilibrium with the convex portion 13c and the surface opposite to the convex portion 13c of the first concave hole portion 311. And have. The first concave hole portion 311 is formed to be longer than the length of the convex portion 13c in the longitudinal direction. Moreover, the 1st recessed hole part 311 is formed so that it may reach an outer side rather than the both ends of the longitudinal direction of the convex part 13c.

図４、図５に示す緩衝用梱包材３０を用いて、ＤＶＤレコーダ６の段ボール箱７への収納を図を用いて説明する。図６は図４、図５に示す緩衝用梱包材を用いてＤＶＤレコーダを梱包箱に収納したときの断面図である。図６に示すように、段ボール箱７に収納された緩衝用梱包材３０は段ボール箱７の側壁部７１と当接することで、凸部１３ｃが形成されている緩衝用梱包材３０の外壁部３２が第１凹孔部３１１側に押し込まれて変形する。凸部１３ｃが第１凹孔部３１１に入り込むことで、段ボール箱７の側壁部７１が膨らむのを抑制することが可能である。   The storing of the DVD recorder 6 in the cardboard box 7 will be described with reference to the drawings using the cushioning packing material 30 shown in FIGS. FIG. 6 is a cross-sectional view of the DVD recorder stored in a packing box using the cushioning packing material shown in FIGS. As shown in FIG. 6, the cushioning packing material 30 stored in the cardboard box 7 abuts against the side wall portion 71 of the cardboard box 7, so that the outer wall portion 32 of the cushioning packaging material 30 on which the convex portions 13 c are formed. Is pushed into the first concave hole 311 side and deformed. It is possible for the side wall 71 of the cardboard box 7 to be prevented from bulging because the convex portion 13 c enters the first concave hole portion 311.

また、図４に示すように、凹孔３１には、第２凹孔部３１２の上下に当接部３１３が形成されている。ＤＶＤレコーダ６が収納された段ボール箱７が落下したり、他の物品が接触したりして、側壁部７１に外力が付与した場合であっても、緩衝用梱包材３０の外壁部３２の内部が当接部３１３と当接し、当接部３１３が衝撃を吸収するので、ＤＶＤレコーダ６に衝撃が伝達されず、衝撃によって破損したり、故障したりするのを抑制することができる。なお、この当接部３１３の厚みＨは、少なくとも落下時の衝撃を吸収し、衝撃がＤＶＤレコーダ６に伝達されない厚さのものが好ましい。   In addition, as shown in FIG. 4, a contact portion 313 is formed in the concave hole 31 above and below the second concave hole portion 312. Even if the cardboard box 7 in which the DVD recorder 6 is stored falls or other articles come into contact with each other and an external force is applied to the side wall 71, the inside of the outer wall 32 of the cushioning packing material 30. Comes into contact with the contact portion 313, and the contact portion 313 absorbs the impact, so that the impact is not transmitted to the DVD recorder 6, and it is possible to suppress damage or failure due to the impact. The thickness H of the contact portion 313 is preferably a thickness that absorbs at least the impact when dropped and does not transmit the impact to the DVD recorder 6.

なお、緩衝用梱包材ユニット１を分解するときに連結部１３が緩衝用梱包材４０との境界部で分割された場合を説明したが、緩衝用梱包材３０と同様に緩衝用梱包材４０も同様に第１凹孔部４１１及び第２凹孔部４１２とを有する凹孔４１が形成されている。このことによって、緩衝用梱包材ユニット１を分解するときに、連結部１３が緩衝用梱包材３０との境界で分割され、凸部が緩衝用梱包財４０のみに形成された場合であっても同様に変形し、側壁部７１が膨らむのを抑制することが可能である。   In addition, although the case where the connection part 13 was divided | segmented in the boundary part with the buffer packaging material 40 when disassembling the buffer packaging material unit 1 was demonstrated, the buffer packaging material 40 is also the same as the buffer packaging material 30. Similarly, a concave hole 41 having a first concave hole portion 411 and a second concave hole portion 412 is formed. Thus, when disassembling the shock-absorbing packing material unit 1, even when the connecting portion 13 is divided at the boundary with the shock-absorbing packing material 30 and the convex portion is formed only on the shock-absorbing packing material 40. Similarly, the side wall 71 can be prevented from bulging by being deformed.

図７は本発明にかかる緩衝用梱包材の他の例の断面図である。図７に示すように、緩衝用梱包材３及び緩衝用梱包材４の第１凹孔部３１１、４１１には、凹孔３１、４１の開口部にいくにしたがって拡がる傾斜が形成された拡大部３１３、４１３が形成されている。このように拡大部３１３、４１３が形成されていることで、図２或いは図４に示されるように、凸部１３ａ、１３ｂ、１３ｃが第１凹孔部３１１或いは４１１の内部に入り込みやすく、それだけ、段ボール箱７の側壁部７１が膨らみにくい。   FIG. 7 is a cross-sectional view of another example of the cushioning packing material according to the present invention. As shown in FIG. 7, the first recessed hole portions 311 and 411 of the cushioning packing material 3 and the cushioning packing material 4 have an enlarged portion formed with an inclination that expands toward the opening of the recessed holes 31 and 41. 313 and 413 are formed. Since the enlarged portions 313 and 413 are formed in this way, as shown in FIG. 2 or FIG. 4, the convex portions 13a, 13b, and 13c easily enter the first concave hole portion 311 or 411. The side wall 71 of the cardboard box 7 is difficult to swell.
