Description

本発明は、データなどを記録するための磁気テープなどを収容したカートリッジの包装に適した包装容器に関する。 The present invention relates to a packaging container suitable for packaging a cartridge containing a magnetic tape or the like for recording data or the like.

例えば、単リール型のテープカートリッジでは、図２に示すごとく、角箱状の本体ケース３の内部に、磁気テープが巻かれる一つのリール５を収容してあり、本体ケース３の一つの角部３ａに傾斜面３ｂを角落とし形成し、この傾斜面３ｂに磁気テープを繰り出すためのテープ引出口６が開口している。 For example, in a single reel type tape cartridge, as shown in FIG. 2, one reel 5 around which a magnetic tape is wound is accommodated in a rectangular box-shaped main body case 3, and one corner portion of the main body case 3 is accommodated. An inclined surface 3b is formed on the inclined surface 3a with a corner, and a tape outlet 6 for feeding the magnetic tape is opened on the inclined surface 3b.

本体ケース３の前記一角部３ａは、テープ引出口６が開口している分だけ強度が低下している。このため、特許文献１〜３などに示す包装容器にテープカートリッジ１を梱包した状態において、落下衝撃を受けると本体ケース３の前記一角部３ａが損傷しやすい。 The corner portion 3 a of the main body case 3 is reduced in strength by the amount of opening of the tape outlet 6. For this reason, in the state which packed the tape cartridge 1 in the packaging container shown in patent documents 1-3 etc., if the drop impact is received, the said corner | angular part 3a of the main body case 3 will be easy to be damaged.

そこで、本出願人は、図１に示すごとく、テープカートリッジ１のテープ引出口６を有する一角部３ａが包装容器の内面角と対峙しないようテープカートリッジ１を収容し、落下衝撃がテープカートリッジ１の該当の一角部３ａに直接加わらないようにすることを検討した。 Therefore, as shown in FIG. 1, the applicant stores the tape cartridge 1 so that the corner 3 a having the tape outlet 6 of the tape cartridge 1 does not face the inner corner of the packaging container, and the drop impact of the tape cartridge 1 It was studied not to directly add to the corresponding corner 3a.

しかし、包装容器にテープカートリッジ１を収容する際に、テープカートリッジ１の向きを誤った状態で収容するおそれがあり、この点を配慮する必要性があることを知った。 However, when storing the tape cartridge 1 in the packaging container, there is a possibility that the tape cartridge 1 may be stored in the wrong direction, and it has been found that there is a need to consider this point.

そこで、本発明の目的は、カートリッジが誤った向きで収容されることを確実に防止し、落下衝撃を受けてもカートリッジの特に開口部（テープ引出口）を有する一角部が損傷し難い包装容器を提供することにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reliably prevent a cartridge from being stored in a wrong orientation and to prevent damage to a corner portion having an opening (tape outlet) of the cartridge even when subjected to a drop impact. Is to provide.

本発明が対象とする包装容器は、図２に示すごとく角箱状の本体ケース３の一つの角部３ａが角落とし状に形成されていて、その一角部３ａに開口する開口部６を有するカートリッジ１を、図１に示すごとく左右方向に複数列並べた状態で包装する。ここでのカートリッジ１は、磁気テープが巻かれる一つのリール５を収容した単リール型のテープカートリッジなどが該当する。 As shown in FIG. 2, the packaging container targeted by the present invention has one corner 3 a of a rectangular box-shaped main body case 3 formed in a corner drop shape, and has an opening 6 that opens to the corner 3 a. The cartridge 1 is packaged in a state where a plurality of rows are arranged in the left-right direction as shown in FIG. Here, the cartridge 1 corresponds to a single reel type tape cartridge that accommodates one reel 5 around which a magnetic tape is wound.

本発明の包装容器は、各カートリッジ１の前記一角部３ａが上側に向き、かつ左右両端のカートリッジ１・１の前記一角部３ａが包装容器の左右中央側に向く姿勢で包装されるよう設定してあり、カートリッジ１の上側を覆う蓋２２の内面には、規制突起２５・２６が設けられていて、この規制突起２５・２６が、本体ケース３の前記一角部３ａの角落としによって包装容器内に生じた空間２７・２９に入り込むようにしたことを特徴とする。蓋２２は、上蓋の場合と底蓋の場合とが該当し、蓋２２に対面する側がカートリッジ１の上側になる。 The packaging container of the present invention is set so that the corner 3a of each cartridge 1 is directed upward and the corner 3a of the cartridges 1 and 1 at both left and right ends is packaged in a posture toward the center of the left and right of the packaging container. The inner surface of the lid 22 that covers the upper side of the cartridge 1 is provided with restricting protrusions 25 and 26. The restricting protrusions 25 and 26 are formed inside the packaging container by dropping the corners 3a of the main body case 3. It is characterized in that it enters the spaces 27 and 29 generated in the above. The lid 22 corresponds to the case of an upper lid and the case of a bottom lid, and the side facing the lid 22 is the upper side of the cartridge 1.

具体的には、図３に示すごとく、四角形状の外箱９と、この外箱９内に収容されてカートリッジ１を覆う内装部材１０とを備えており、内装部材１０は、カートリッジ１の上側を覆う蓋壁２２を含み、蓋壁２２の内面に規制突起２５・２６を配してある。 Specifically, as shown in FIG. 3, a rectangular outer box 9 and an interior member 10 that is accommodated in the outer box 9 and covers the cartridge 1 are provided. The control projections 25 and 26 are arranged on the inner surface of the cover wall 22.

複数個のカートリッジ１を前記一角部３ａが同じ向きになるよう揃えた状態で、前後方向に重ねて結束したカートリッジ束２を形成し、このカートリッジ束２を、左右方向に複数個並べた状態で包装する。前記カートリッジ１の結束は、帯体Ｔのみでの結束や、シュリンク包装のみによる結束などが含まれる。 In a state in which a plurality of cartridges 1 are aligned so that the corners 3a are in the same direction, a cartridge bundle 2 is formed by bundling them in the front-rear direction, and a plurality of cartridge bundles 2 are arranged in the left-right direction. Packaging. The bundling of the cartridge 1 includes bundling only by the belt T, bundling only by shrink wrapping, and the like.

本発明によれば、各カートリッジ１を正しい向きで梱包したときには、規制突起２５・２６が空間２７・２９に入り込んで、蓋２２がカートリッジ１の上側を適正に覆う。このときには、左右両端のカートリッジ１・１の一角部３ａが、包装容器の左右中央側にそれぞれ向いているので、包装容器を誤って落下させても、その落下衝撃がカートリッジ１の一角部３ａに加わり難く、該当部位をよく保護する。 According to the present invention, when the cartridges 1 are packed in the correct orientation, the restricting projections 25 and 26 enter the spaces 27 and 29, and the lid 22 appropriately covers the upper side of the cartridge 1. At this time, since the corners 3a of the cartridges 1 and 1 at the left and right ends are respectively directed to the left and right central sides of the packaging container, even if the packaging container is accidentally dropped, the drop impact is applied to the corner 3a of the cartridge 1. It is hard to join and protects the corresponding part well.

左右両端のカートリッジ１・１のいずれか一方の向きを間違えて包装容器に梱包したときには、規制突起２５・２６がカートリッジ１の上面に突き当たって、蓋２２は半開き状態になる。これにより、カートリッジ１の向きが間違っていることに気付き、カートリッジ１を正しい向きに修正できる。 When one of the cartridges 1 and 1 at the left and right ends is mistakenly packed in the packaging container, the regulation protrusions 25 and 26 abut against the upper surface of the cartridge 1 and the lid 22 is in a half-open state. Thereby, it is noticed that the orientation of the cartridge 1 is wrong, and the cartridge 1 can be corrected to the correct orientation.

カートリッジ１を外箱９と内装部材１０とで二重に覆うと、落下衝撃をより緩和できてカートリッジ１の損傷防止に有利である。 If the cartridge 1 is covered twice with the outer box 9 and the interior member 10, the drop impact can be further reduced, which is advantageous for preventing damage to the cartridge 1.

複数個のカートリッジ１でカートリッジ束２を形成して包装容器に収容する場合、多数のカートリッジ１であっても正しい向きで包装容器に丸ごと収容でき、カートリッジ１が確実に損傷し難くなる。 When the cartridge bundle 2 is formed with a plurality of cartridges 1 and accommodated in a packaging container, even a large number of cartridges 1 can be accommodated in the packaging container in the correct orientation, and the cartridge 1 is hardly damaged.

図面は、本発明が対象とする包装容器の実施例を示す。ここでの包装容器は、図３に示す四角形状のカートリッジ束２を左右方向に３列並べた状態で包装することを想定している。カートリッジ束２は、図２に示すごとく、１０個のテープカートリッジ１を前後（厚み）方向に重ねた状態で帯体Ｔで束ねたのちに、これらの外周を熱収縮性フィルムＦでシュリンク包装したものである。 The drawings show examples of packaging containers to which the present invention is directed.

And a lid wall (lid) 22.

緩衝板１６・１６は、それぞれ前後方向に長い扁平長方形状に形成されており、図１に示すごとく、３個のカートリッジ束２と、外箱９の箱本体１１の左右内面との間に縦姿勢でそれぞれ配される。各緩衝板１６の高さは、外箱９内に配した状態で内装本体１５の前後の内壁２０・２１の上端部位よりも突出するよう寸法設定した。 The buffer plates 16 and 16 are each formed in a flat rectangular shape that is long in the front-rear direction. As shown in FIG. 1, the buffer plates 16 and 16 are vertically disposed between the three cartridge bundles 2 and the left and right inner surfaces of the box body 11 of the outer box 9. Each is arranged in a posture. The height of each buffer plate 16 was set so as to protrude from the upper end portions of the inner walls 20 and 21 before and after the interior body 15 in a state of being arranged in the outer box 9.

内装本体１５の蓋壁２２の内面には、図１および図５に示すごとく、前後方向に延びる左右一対の規制突起２５・２６が固定されている。左右の規制突起２５・２６は、段ボールや発泡スチロールなどで形成した。 As shown in FIGS. 1 and 5, a pair of left and right restricting protrusions 25 and 26 extending in the front-rear direction are fixed to the inner surface of the lid wall 22 of the interior body 15. The left and right restricting protrusions 25 and 26 were formed of corrugated cardboard or polystyrene foam.

左側の規制突起２５は、図１に示すごとく、左端のカートリッジ束２におけるテープカートリッジ１の前記一角部３ａと、中央のカートリッジ束２におけるテープカートリッジ１の前記一角部３ａとによって包装容器内に形成された断面三角形の左側空間２７内に入り込む。右側の規制突起２６は、右端のカートリッジ束２のテープカートリッジ１の前記一角部３ａによって包装容器内に形成された断面三角形の右側空間２９内に入り込む。 As shown in FIG. 1, the left regulation protrusion 25 is formed in the packaging container by the corner 3a of the tape cartridge 1 in the cartridge bundle 2 at the left end and the corner 3a of the tape cartridge 1 in the cartridge bundle 2 at the center. It enters the left space 27 of the cross-sectional triangle. The right restricting protrusion 26 enters the right space 29 having a triangular cross section formed in the packaging container by the one corner portion 3a of the tape cartridge 1 of the cartridge bundle 2 at the right end.

梱包に際しては、内装本体１５の底壁１９に対して前後の内壁２０・２１をそれぞれ折線Ｌ１・Ｌ２を介して直角に内折りする。この後、内装本体１５を外箱９内に収容し、内装本体１５の底壁１９上に３個のカートリッジ束２を左右方向に並べて載置し、外箱９に緩衝板１６・１６をそれぞれ配する。この際、左端、中央および右端の各カートリッジ束２は、先に説明した向きに載置する。 In packaging, the front and rear inner walls 20 and 21 are folded at right angles with respect to the bottom wall 19 of the interior body 15 via folding lines L1 and L2, respectively. Thereafter, the interior body 15 is accommodated in the outer box 9, the three cartridge bundles 2 are placed side by side on the bottom wall 19 of the interior body 15, and the buffer plates 16, 16 are placed on the outer box 9. Arrange. At this time, the cartridge bundles 2 at the left end, the center, and the right end are placed in the direction described above.

次いで、内装本体１５の後側内壁２１に対して蓋壁２２を折線Ｌ３を介して直角に内折りする。これによって、左右の規制突起２５・２６が左右の空間２７・２９にそれぞれ入り込み、３列のカートリッジ束２の上側に蓋壁２２が密着する（図１の状態）。最後に、外箱９の内フラップ１２・１２と外フラップ１３・１３とを箱本体１１に対して直角に内折りして、箱本体１１の開口上端を閉じる。この包装状態で、カートリッジ束２は内装部材１０に密着し、内装部材１０が外箱９の内面に密着して、３列のカートリッジ束２が外箱９と内装部材１０とで二重に覆われる。 Next, the lid wall 22 is folded inward at a right angle with respect to the rear inner wall 21 of the interior main body 15 via the folding line L3. As a result, the left and right restricting projections 25 and 26 enter the left and right spaces 27 and 29, respectively, and the lid wall 22 is in close contact with the upper side of the three rows of cartridge bundles 2 (state shown in FIG. 1). Finally, the inner flaps 12 and 12 and the outer flaps 13 and 13 of the outer box 9 are folded in at a right angle with respect to the box body 11 to close the upper open end of the box body 11. In this packaging state, the cartridge bundle 2 is in close contact with the interior member 10, the interior member 10 is in intimate contact with the inner surface of the outer box 9, and the three rows of cartridge bundles 2 are covered by the outer case 9 and the interior member 10. Is called.

例えば、左右両端のカートリッジ束２のうち、いずれか一方のカートリッジ束２の向きを間違えた状態で、内装本体１５の底壁１９上に載置したときには、規制突起２５・２６の一方がカートリッジ束２の上面に突き当たって、蓋壁２２は半開き状態になる。これで作業者は、カートリッジ束２の向きが間違っていることに気付き、カートリッジ束２の向きを修正できる。 For example, when one of the cartridge bundles 2 at the left and right ends is placed on the bottom wall 19 of the interior main body 15 in a state where one of the cartridge bundles 2 is in the wrong direction, one of the restricting protrusions 25 and 26 is not in the cartridge bundle. 2, the lid wall 22 is in a half-opened state. Thus, the operator can recognize that the orientation of the cartridge bundle 2 is wrong and can correct the orientation of the cartridge bundle 2.

開梱に際しては、外箱９の外フラップ１３・１３と内フラップ１２・１２とを開いて、内装本体１５の蓋壁２２を起立させたのち、左右の緩衝板１６・１６を、それぞれ上方に引っ張って外箱９から引き抜く。これによってカートリッジ束２と外箱９の左右の内面との間に生じた隙間に、指などを差し入れてカートリッジ束２を包装容器から引き出す。 When unpacking, the outer flaps 13 and 13 and the inner flaps 12 and 12 of the outer box 9 are opened, the lid wall 22 of the interior body 15 is raised, and the left and right buffer plates 16 and 16 are moved upward. Pull it out of the outer box 9. As a result, a finger or the like is inserted into the gap formed between the cartridge bundle 2 and the left and right inner surfaces of the outer box 9 to pull out the cartridge bundle 2 from the packaging container.

蓋壁２２は、内装本体１５とは別に形成してもよい。外箱９内に内装部材１０を配しない場合には、外箱９の内フラップ１２・１２の内面に規制突起２５・２６を配してもよい。 The lid wall 22 may be formed separately from the interior body 15. When the interior member 10 is not arranged in the outer box 9, the regulation protrusions 25 and 26 may be arranged on the inner surfaces of the inner flaps 12 and 12 of the outer box 9.

内装本体１５の底壁（底蓋）１９の内面に規制突起２５・２６を配してもよい。この場合、テープカートリッジ１の一角部３ａを底壁１９側に向けることになる。隣り合うカートリッジ束２・２間にも緩衝板１６を配することができる。外箱９や内装部材１０は、合成樹脂製の段ボールであってもよい。 The restriction protrusions 25 and 26 may be arranged on the inner surface of the bottom wall (bottom lid) 19 of the interior body 15. In this case, one corner 3a of the tape cartridge 1 is directed toward the bottom wall 19 side. The buffer plate 16 can also be disposed between the adjacent cartridge bundles 2. The outer box 9 and the interior member 10 may be cardboard made of synthetic resin.
