Description

本発明は、包装部材に関し、特に、被梱包物を保護する緩衝材と、被梱包物および緩衝材を収納する箱体と、を備えた包装部材に関する。 The present invention relates to a packaging member, and more particularly to a packaging member including a cushioning material for protecting the packaged object and a box body for storing the packaged object and the cushioning material.

従来、電子機器等の製品（被梱包物）を包装するための包装部材が知られている。包装部材としては、製品を衝撃から保護する緩衝材と、製品および緩衝材を収納する箱体と、を備えたものが知られている。 Conventionally, packaging members for packaging products (packaged objects) such as electronic devices have been known. As a packaging member, a material including a cushioning material that protects the product from impact and a box body that stores the product and the cushioning material is known.

このような包装部材を用いて製品を梱包する場合、緩衝材を箱体内に配置した後、製品を箱体内に収納して蓋を閉じる。 When the product is packed using such a packaging member, the cushioning material is placed inside the box, and then the product is stored inside the box and the lid is closed.

なお、製品を衝撃から保護する緩衝材と、製品および緩衝材を収納する箱体と、を備えた包装部材は、例えば特許文献１に開示されている。 A packaging member including a cushioning material that protects the product from impact and a box body that stores the product and the cushioning material is disclosed in, for example, Patent Document 1.

特開２０１４－４６９３１号公報Japanese Unexamined Patent Publication No. 2014-46931

しかしながら、上記従来の包装部材では、箱体に対して緩衝材を固定していないため、緩衝材を箱体内に配置した状態で箱体を例えば逆さまにした場合などに、緩衝材が箱体から落下したり、緩衝材が箱体の底面から浮き上がったりしてしまう。このため、梱包作業性が低下するという問題点があった。 However, in the above-mentioned conventional packaging member, since the cushioning material is not fixed to the box body, when the cushioning material is placed inside the box and the box body is turned upside down, for example, the cushioning material is released from the box body. It may fall or the cushioning material may rise from the bottom of the box. Therefore, there is a problem that the packing workability is lowered.

本発明は、上記のような課題を解決するためになされたものであり、本発明の目的は、梱包作業性を向上させることが可能な包装部材を提供することである。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a packaging member capable of improving packing workability.

上記目的を達成するために、本発明の第１の構成の包装部材は、被梱包物を保護する緩衝材と、被梱包物および緩衝材を収納する箱体と、を備える。緩衝材の外側面は、上方に向かって緩衝材の内方向に傾斜している。箱体は、矩形状の底面部と、底面部の周縁に立設される４つの側面部と、を有する。対向する一対の側面部の端部の内面には、隣接する側面部の端部に折り線を介して連設された固定片が固定されている。対向する固定片の各々には、固定片の上端から所定の距離を隔てて切り欠き部が形成されている。緩衝材を箱体内に配置した状態で、緩衝材の一部は切り欠き部の内部に配置される。 In order to achieve the above object, the packaging member of the first configuration of the present invention includes a cushioning material for protecting the packaged object and a box body for storing the packaged object and the cushioning material. The outer surface of the cushioning material is inclined inwardly toward the cushioning material. The box body has a rectangular bottom surface portion and four side surface portions erected on the peripheral edge of the bottom surface portion. A fixed piece connected to the end of the adjacent side surface portion via a fold line is fixed to the inner surface of the end portions of the pair of side surface portions facing each other. Notches are formed in each of the facing fixed pieces at a predetermined distance from the upper end of the fixed pieces. With the cushioning material placed inside the box, a part of the cushioning material is placed inside the notch.

本発明の第１の構成の包装部材によれば、対向する固定片の各々には、固定片の上端から所定の距離を隔てて切り欠き部が形成されており、緩衝材を箱体内に配置した状態で、緩衝材の一部は切り欠き部の内部に配置される。これにより、緩衝材を箱体内に配置した状態で箱体を例えば逆さまにしたとしても、緩衝材の一部が切り欠き部の上縁に係合するので、緩衝材が箱体から落下したり箱体の底面から浮き上がったりするのを抑制することができる。このため、梱包作業性を向上させることができる。 According to the packaging member having the first configuration of the present invention, a notch is formed in each of the facing fixing pieces at a predetermined distance from the upper end of the fixing piece, and the cushioning material is arranged in the box. In this state, a part of the cushioning material is arranged inside the notch. As a result, even if the box body is turned upside down with the cushioning material placed inside the box, a part of the cushioning material engages with the upper edge of the notch, so that the cushioning material may fall from the box body. It is possible to prevent the box from rising from the bottom of the box. Therefore, the packing workability can be improved.

図１に示すように、本発明の一実施形態の包装部材１は、被梱包物５０（例えば電子機器等の製品）が載置される下ケース（箱体）１０と、下ケース１０内に配置され被梱包物５０を外部衝撃から保護する緩衝材２０と、底面が開口しているとともに、上方から被梱包物５０および緩衝材２０に被せられる上ケース３０とを備えている。 As shown in FIG. 1, the packaging member 1 according to the embodiment of the present invention includes a lower case (box body) 10 on which an object to be packed 50 (for example, a product such as an electronic device) is placed, and a lower case 10 inside the lower case 10. It is provided with a cushioning material 20 that is arranged and protects the packaged object 50 from an external impact, and an upper case 30 that has an open bottom surface and is covered with the packaged object 50 and the cushioning material 20 from above.

下ケース１０は図２に示すように、矩形状の底面部１１と、底面部１１の周縁に立設された４つの側面部１２と、を含んでいる。下ケース１０の側面部１２の所定の位置には、貫通穴１５が形成されている。上ケース３０は図１に示すように、底面が開口しているとともに、上面部３１と、上面部３１の周縁から下方に延びるように設けられた４つの側面部３２と、を含んでいる。上ケース３０の下端部には、下ケース１０の貫通穴１５と重なる位置に貫通穴３５が形成されている。貫通穴１５と貫通穴３５とを重ねた状態で図示しない留め具を差し込むことにより、下ケース１０と上ケース３０とが一体に連結される。なお、本実施形態では、上ケース３０は、下ケース１０の側面部１２の外側を覆うように配置される。 As shown in FIG. 2, the lower case 10 includes a rectangular bottom surface portion 11 and four side surface portions 12 erected on the peripheral edge of the bottom surface portion 11. A through hole 15 is formed at a predetermined position on the side surface portion 12 of the lower case 10. As shown in FIG. 1, the upper case 30 includes an upper surface portion 31 and four side surface portions 32 provided so as to extend downward from the peripheral edge of the upper surface portion 31 as well as having an open bottom surface. At the lower end of the upper case 30, a through hole 35 is formed at a position overlapping the through hole 15 of the lower case 10. The lower case 10 and the upper case 30 are integrally connected by inserting a fastener (not shown) in a state where the through hole 15 and the through hole 35 are overlapped with each other. In this embodiment, the upper case 30 is arranged so as to cover the outside of the side surface portion 12 of the lower case 10.

図２に示すように、下ケース１０の側面部１２は、矢印ＡＡ´方向に対向配置された一対の第１側面部１２ａと、矢印ＢＢ´方向に対向配置された一対の第２側面部１２ｂと、を含んでいる。 As shown in FIG. 2, the side surface portions 12 of the lower case 10 are a pair of first side surface portions 12a arranged to face each other in the direction of arrow AA'and a pair of second side surface portions 12b arranged to face each other in the direction of arrow BB'. And, including.

下ケース１０は、段ボールシートからなるシート材１０ａ（図３参照）を所定の位置で折り曲げることによって形成されている。シート材１０ａは図３に示すように、底面部１１と、底面部１１の矢印ＡＡ´方向の端縁に設けられた一対の第１側面部１２ａと、底面部１１の矢印ＢＢ´方向の端縁に設けられた一対の第２側面部１２ｂと、を有する。一対の第２側面部１２ｂの矢印ＡＡ´方向の両端には、折り線Ｌを介して固定片１３が連設されている。なお、図３では、折り曲げ位置を一点鎖線で示している。 The lower case 10 is formed by bending a sheet material 10a (see FIG. 3) made of a corrugated cardboard sheet at a predetermined position. As shown in FIG. 3, the sheet material 10a has a bottom surface portion 11, a pair of first side surface portions 12a provided on the edge of the bottom surface portion 11 in the direction of arrow AA', and an end of the bottom surface portion 11 in the direction of arrow BB'. It has a pair of second side surface portions 12b provided on the edge. Fixing pieces 13 are continuously provided at both ends of the pair of second side surface portions 12b in the direction of the arrow AA'via the folding line L. In addition, in FIG. 3, the bent position is shown by a alternate long and short dash line.

下ケース１０を組み立てる場合、第２側面部１２ｂを底面部１１に対して折り曲げるとともに、固定片１３を第２側面部１２ｂに対して折り曲げる。そして、第１側面部１２ａを底面部１１に対して折り曲げる。これにより、第１側面部１２ａの矢印ＢＢ´方向の両端部の内面に固定片１３が対向配置される。そして、固定片１３と第１側面部１２ａとを接着固定することによって、図２に示した下ケース１０が得られる。 When assembling the lower case 10, the second side surface portion 12b is bent with respect to the bottom surface portion 11, and the fixing piece 13 is bent with respect to the second side surface portion 12b. Then, the first side surface portion 12a is bent with respect to the bottom surface portion 11. As a result, the fixing pieces 13 are arranged to face each other on the inner surfaces of both ends of the first side surface portion 12a in the direction of the arrow BB'. Then, by adhesively fixing the fixing piece 13 and the first side surface portion 12a, the lower case 10 shown in FIG. 2 can be obtained.

ここで、図２に示すように、固定片１３の各々には、固定片１３の上端から所定の距離を隔てて切り欠き部１４が形成されている。本実施形態では、切り欠き部１４は、固定片１３の下端に設けられている。また、切り欠き部１４は、底面部１１と平行に延びるように細長状に形成されている。 Here, as shown in FIG. 2, each of the fixed pieces 13 is formed with a notch portion 14 at a predetermined distance from the upper end of the fixed piece 13. In the present embodiment, the notch portion 14 is provided at the lower end of the fixed piece 13. Further, the notch portion 14 is formed in an elongated shape so as to extend in parallel with the bottom surface portion 11.

また、固定片１３には、切り欠き部１４に対して折り線Ｌと反対側の部分に、後述するように緩衝材２０が切り欠き部１４の延在方向へ移動するのを規制する規制部１３ａが設けられている。 Further, the fixing piece 13 has a regulating portion that regulates the movement of the cushioning material 20 in the extending direction of the notch portion 14 at a portion opposite to the fold line L with respect to the notch portion 14, as will be described later. 13a is provided.

緩衝材２０は図４に示すように、下ケース１０内に一対配置される。緩衝材２０は、矢印ＡＡ´方向に延びるように配置されるとともに、下ケース１０の底面部１１の矢印ＢＢ´方向の両端部に配置される。 As shown in FIG. 4, a pair of cushioning materials 20 are arranged in the lower case 10. The cushioning material 20 is arranged so as to extend in the direction of arrow AA', and is arranged at both ends of the bottom surface portion 11 of the lower case 10 in the direction of arrow BB'.

図５に示すように、緩衝材２０には、被梱包物５０の下部の一部が配置されるとともに、矢印ＡＡ´方向に延びる凹部２０ａが設けられている。具体的には、緩衝材２０は、被梱包物５０の下部の一部が配置される本体部２１と、本体部２１の矢印ＡＡ´方向の両端部に設けられ被梱包物５０の矢印ＡＡ´方向の側面を保護する一対の側壁部２２と、本体部２１の矢印ＢＢ´方向の外側（図５では左方向）の端部に設けられ被梱包物５０の矢印ＢＢ´方向の側面を保護する側壁部２３と、を有する。本体部２１、一対の側壁部２２、及び側壁部２３によって、凹部２０ａが形成されている。なお、側壁部２３の矢印ＡＡ´方向の中央部には、留め具（図示せず）との接触を回避するために凹状の逃げ部２３ａが形成されている。また、緩衝材２０の矢印ＢＢ´方向の長さは、下ケース１０の切り欠き部１４の矢印ＢＢ´方向の長さよりも少しだけ短く又は同じ長さに形成されている。 As shown in FIG. 5, the cushioning material 20 is provided with a portion of the lower portion of the packaged object 50 and a recess 20a extending in the direction of the arrow AA'. Specifically, the cushioning material 20 is provided at both ends of the main body portion 21 in which a part of the lower portion of the packed object 50 is arranged and both ends of the main body portion 21 in the direction of the arrow AA', and the arrow AA'of the packed object 50 is provided. A pair of side wall portions 22 that protect the side surfaces in the direction and an end portion of the main body portion 21 outside the arrow BB'direction (left direction in FIG. 5) are provided to protect the side surface of the packaged object 50 in the arrow BB'direction. It has a side wall portion 23 and. The recess 20a is formed by the main body portion 21, the pair of side wall portions 22, and the side wall portions 23. A concave relief portion 23a is formed in the central portion of the side wall portion 23 in the direction of the arrow AA'in order to avoid contact with a fastener (not shown). Further, the length of the cushioning material 20 in the arrow BB'direction is slightly shorter than or the same length as the length of the cutout portion 14 of the lower case 10 in the arrow BB' direction.

緩衝材２０は、パルプモールド成型体であり、金型を用いてパルプ材を成型することにより形成される。このため、緩衝材２０を金型から抜き取りやすくするために抜き勾配が必要であるので、緩衝材２０の全ての側面は、上方に向かって緩衝材２０が細くなるように傾斜している。 The cushioning material 20 is a pulp molded body, and is formed by molding a pulp material using a mold. Therefore, since a draft is required to facilitate the removal of the cushioning material 20 from the mold, all the side surfaces of the cushioning material 20 are inclined so that the cushioning material 20 becomes thinner toward the upper side.

具体的には、図６に示すように、緩衝材２０の矢印ＡＡ´方向の両端に設けられる一対の外側面２４ａ、凹部２０ａの矢印ＡＡ´方向の両端面を形成する一対の内側面２４ｂ、及び逃げ部２３ａの矢印ＡＡ´方向の両端面を形成する一対の内側面２４ｃは、鉛直方向に対して約５度（抜き勾配）だけ傾斜している。また、図７に示すように、緩衝材２０の矢印ＢＢ´方向の内方向（図７では右方向）に設けられる外側面２４ｄ、緩衝材２０の矢印ＢＢ´方向の外方向（図７では左方向）に設けられる外側面２４ｅ、及び凹部２０ａの矢印ＢＢ´方向の外方向（図７では左方向）の端面を形成する内側面２４ｆは、鉛直方向に対して約５度（抜き勾配）だけ傾斜している。なお、緩衝材２０の外周面を形成する一対の外側面２４ａ、外側面２４ｄ、及び外側面２４ｅは、上方に向かって緩衝材２０の内方向に傾斜している。 Specifically, as shown in FIG. 6, a pair of outer surfaces 24a provided at both ends of the cushioning material 20 in the direction of arrow AA', and a pair of inner side surfaces 24b forming both end faces of the recess 20a in the direction of arrow AA'. The pair of inner side surfaces 24c forming both end faces in the arrow AA'direction of the relief portion 23a are inclined by about 5 degrees (draft) with respect to the vertical direction. Further, as shown in FIG. 7, the outer surface 24d provided in the inner direction (right direction in FIG. 7) of the cushioning material 20 in the arrow BB'direction and the outer direction of the cushioning material 20 in the arrow BB' direction (left in FIG. 7). The outer surface 24e provided in the direction) and the inner surface 24f forming the end surface in the outer direction (left direction in FIG. 7) in the arrow BB'direction of the recess 20a are only about 5 degrees (draft) with respect to the vertical direction. It is tilted. The pair of outer surface 24a, outer surface 24d, and outer surface 24e forming the outer peripheral surface of the cushioning material 20 are inclined inward of the cushioning material 20 inward.

緩衝材２０を下ケース１０内に配置した状態（図４の状態）で、図８に示すように、緩衝材２０の下端部の一部は切り欠き部１４の内部に配置されている。また、本実施形態では、緩衝材２０を下ケース１０内に配置した状態で、緩衝材２０の外側面２４ａは、第１側面部１２ａの内面に当接している。なお、緩衝材２０を下ケース１０内に配置した状態で、切り欠き部１４の上縁１４ａが緩衝材２０の外側面２４ａに当接（又は近接）していることが好ましい。 In a state where the cushioning material 20 is arranged in the lower case 10 (state in FIG. 4), as shown in FIG. 8, a part of the lower end portion of the cushioning material 20 is arranged inside the notch portion 14. Further, in the present embodiment, the outer surface 24a of the cushioning material 20 is in contact with the inner surface of the first side surface portion 12a in a state where the cushioning material 20 is arranged in the lower case 10. It is preferable that the upper edge 14a of the notch portion 14 is in contact with (or is close to) the outer surface 24a of the cushioning material 20 in a state where the cushioning material 20 is arranged in the lower case 10.

本実施形態では、上記のように、固定片１３の各々には、切り欠き部１４が形成されており、緩衝材２０を下ケース１０内に配置した状態で、緩衝材２０の一部は切り欠き部１４の内部に配置される。これにより、緩衝材２０を下ケース１０内に配置した状態で下ケース１０を例えば逆さまにしたとしても、緩衝材２０の一部（外側面２４ａ）が切り欠き部１４の上縁１４ａに係合するので、緩衝材２０が下ケース１０から落下したり下ケース１０の底面から浮き上がったりするのを抑制することができる。このため、梱包作業性を向上させることができる。 In the present embodiment, as described above, a notch portion 14 is formed in each of the fixed pieces 13, and a part of the cushioning material 20 is cut while the cushioning material 20 is arranged in the lower case 10. It is arranged inside the notch 14. As a result, even if the lower case 10 is turned upside down while the cushioning material 20 is arranged in the lower case 10, a part (outer surface 24a) of the cushioning material 20 engages with the upper edge 14a of the notch portion 14. Therefore, it is possible to prevent the cushioning material 20 from falling from the lower case 10 or rising from the bottom surface of the lower case 10. Therefore, the packing workability can be improved.

また、緩衝材２０の外側面２４ａの下部が切り欠き部１４の内部に配置されるので、固定片１３に切り欠き部１４が設けられていない場合と比べて、固定片１３の厚み分だけ緩衝材２０の厚み（側壁部２２の矢印ＡＡ´方向の厚み）を大きくすることができる。このため、緩衝材２０の緩衝性能を向上させることができる。 Further, since the lower portion of the outer surface 24a of the cushioning material 20 is arranged inside the notch portion 14, the cushioning material 20 is cushioned by the thickness of the fixing piece 13 as compared with the case where the notch portion 14 is not provided. The thickness of the material 20 (thickness of the side wall portion 22 in the direction of arrow AA') can be increased. Therefore, the cushioning performance of the cushioning material 20 can be improved.

また、上記のように、緩衝材２０を下ケース１０内に配置した状態で、緩衝材２０の外側面２４ａの一部は固定片１３が固定された第１側面部１２ａの内面に当接する。これにより、切り欠き部１４の上縁１４ａに緩衝材２０の一部（外側面２４ａ）がより係合しやすくなるので、緩衝材２０が下ケース１０から落下したり下ケース１０の底面から浮き上がったりするのをより抑制することができる。 Further, as described above, with the cushioning material 20 arranged in the lower case 10, a part of the outer surface 24a of the cushioning material 20 comes into contact with the inner surface of the first side surface portion 12a to which the fixing piece 13 is fixed. As a result, a part of the cushioning material 20 (outer surface 24a) is more easily engaged with the upper edge 14a of the notch portion 14, so that the cushioning material 20 falls from the lower case 10 or rises from the bottom surface of the lower case 10. It is possible to further suppress the cushioning.

また、上記のように、切り欠き部１４は、底面部１１と平行に延びるように形成されている。これにより、緩衝材２０の外側面２４ａが切り欠き部１４の上縁１４ａに係合する領域を容易に大きくすることができる。 Further, as described above, the notch portion 14 is formed so as to extend in parallel with the bottom surface portion 11. As a result, the region where the outer surface 24a of the cushioning material 20 engages with the upper edge 14a of the notch portion 14 can be easily increased.

また、上記のように、固定片１３には、切り欠き部１４に対して折り線Ｌと反対側の部分に、緩衝材２０が切り欠き部１４の延在方向へ移動するのを規制する規制部１３ａが設けられている。これにより、緩衝材２０が下ケース１０の内方向へ移動するのを容易に抑制することができる。 Further, as described above, the fixing piece 13 is regulated to restrict the cushioning material 20 from moving in the extending direction of the notch portion 14 at the portion opposite to the fold line L with respect to the notch portion 14. A portion 13a is provided. As a result, it is possible to easily prevent the cushioning material 20 from moving inward in the lower case 10.

また、上記のように、上ケース３０の側面部３２は、下ケース１０の側面部１２の外側に配置される。これにより、下ケース１０の側面部１２と緩衝材２０との間に上ケース３０の側面部３２を挿入するためのスペースを設けたり、上ケース３０の側面部３２に緩衝材２０を避けるための切り欠きを設けたりする必要がない。 Further, as described above, the side surface portion 32 of the upper case 30 is arranged outside the side surface portion 12 of the lower case 10. As a result, a space for inserting the side surface portion 32 of the upper case 30 is provided between the side surface portion 12 of the lower case 10 and the cushioning material 20, and the cushioning material 20 is avoided on the side surface portion 32 of the upper case 30. There is no need to provide a notch.

また、上記のように、緩衝材２０としてパルプモールド成型体を用いた場合、緩衝材２０の外側面２４ａは上方に向かって緩衝材２０の内方向に傾斜するため、緩衝材２０の側壁部２２の矢印ＡＡ´方向の厚みが小さく（又は下ケース１０が大きく）なってしまう。このため、緩衝材２０の外側面２４ａの下部を切り欠き部１４の内部に配置し、固定片１３の厚み分だけ緩衝材２０の側壁部２２の厚みを大きくすることは、特に効果的である。 Further, as described above, when the pulp molded body is used as the cushioning material 20, the outer surface 24a of the cushioning material 20 is inclined inward of the cushioning material 20 toward the upper side, so that the side wall portion 22 of the cushioning material 20 is used. The thickness in the direction of the arrow AA'is small (or the lower case 10 is large). Therefore, it is particularly effective to arrange the lower portion of the outer surface 24a of the cushioning material 20 inside the notch portion 14 and increase the thickness of the side wall portion 22 of the cushioning material 20 by the thickness of the fixing piece 13. ..
