Description

【０００１】
【発明の属する技術分野】
本発明は、冷蔵庫、洗濯機等の電気製品や空調機器や家具等の大型の物品を梱包する際に、物品の底部に配置される梱包用トレーに関するものである。
【０００２】
【従来の技術】
従来、図６に示されているように、物品Ａの底部ａ１が載置される段部１００を有するとともに、段部１００の外側には、断面形状が略逆Ｕ字状で、下方が開放された周壁部材１０１で囲まれた梱包用トレーが知られている（例えば、特開平９−５８７５１号公報、特開２００１−１５１２６６号公報等）。
【０００３】
【発明が解決しようとする課題】
上述した従来の梱包用トレーにおいては、衝撃が、梱包用トレーに横方向から加わった場合には、断面形状が略逆Ｕ字状で、下方が開放された周壁部材１０１により、その衝撃が吸収され緩和される。また、輸送途中で、梱包された物品Ａが落下する場合があるが、このような落下時には、梱包用トレーのコーナーに、大きな衝撃が加わることになるが、従来の梱包用トレーの場合には、衝撃を吸収緩和する周壁部材１０１が、断面形状が略逆Ｕ字状で、下方が開放された構造であるため、衝撃が、周壁部材１０１の一枚の板材からなる外壁１０１ａの下端部に加わることになる。従って、梱包用トレーが、このような衝撃を、十分に吸収緩和することができず、梱包用トレーや梱包された物品Ａが損傷するという問題があった。
【０００４】
また、梱包用トレーの段部１００に物品Ａを載置するとともに、物品Ａの上部にカバーを配置し、その後、結束紐により緊諦するが、従来の梱包用トレーの場合には、周壁部材１０１が、断面形状が略逆Ｕ字状で、下方が開放された構造である。そのため、結束紐による緊諦により、周壁部材１０１の一枚の板材からなる外壁１０１ａが変形したり破損したりするために、強固に緊諦することができないという問題があった。
【０００５】
本発明は、上記従来の問題点を解決するもので、梱包作業の作業性の向上した梱包用トレーを提供することにある。
【０００６】
【課題を解決するための手段】
本発明は、上述した目的を達成するために、第１の発明は、外周壁部と底部と内周壁部とにより構成された断面形状が略Ｕ字状の周壁部材と、周壁部材の内周壁部と物品が載置される略水平状の載置部と垂直壁とにより構成された環状土手部とを有するとともに、周壁部材に形成された緊諦部材用凹部が位置する周壁部材の外周壁部と緊諦部材用凹部と対向する位置にある周壁部材の内周壁部とが架橋リブにより連結されているものであり、第２の発明は、環状土手部の弾性変形を容易にするために、環状土手部には、環状土手部の長手方向に対して垂直で、且つ、環状土手部の幅と同じ長さを有する適当数の水平凹部が形成されているものであり、第３の発明は、緊諦部材用凹部と環状土手部に形成された凹部とが、環状土手部の長手方向にずらして配置されているものであり、第４の発明は、緊諦部材用凹部が、周壁部材を構成する外周壁部に形成された外周壁部側凹部と、周壁部材を構成する底部に形成された底部側凹部とにより構成されているものであり、第５の発明は、周壁部材を構成する外周壁部が、物品が載置される環状土手部の載置部より高く形成されているものである。
【０００７】
【実施例】
以下に、本発明の実施例について説明するが、本発明の趣旨を越えない限り何ら、本実施例に限定されるものではない。主として、図１及び図２について説明する。
【０００８】
１ａは、平面形状が略方形状で、略垂直に立設された外周壁部であり、外周壁部１ａの下端からは、略水平方向に底部１ｂが延在しており、更に、底部１ｂの先端からは、上方に向かって略垂直に延在するとともに、外周壁部１ａより低い内周壁部１ｃが形成されている。上記の外周壁部１ａ、底部１ｂ及び内周壁部１ｃとにより、断面形状が略Ｕ字状の周壁部材１が構成されている。
【０００９】
周壁部材１を構成する内周壁部１ｃの上端からは、外周壁部１ａに対して反対方向、即ち、梱包用トレーの中央部方向に略水平状に延在する載置部２が形成されている。載置部２の先端からは、略垂直状に下方に延在する垂直壁３が垂下されており、また、垂直壁３の下端からは、周壁部材１の外周壁部１ａに対して反対方向に略水平状に延在する水平部４が形成されている。更に、水平部４の先端からは、下方に傾斜した傾斜部５が形成されており、傾斜部５の下端には、水平状の水平底部６が形成されている。水平底部６は、周壁部材１を構成する底部１ｂより、上方に位置しており、従って、梱包用トレーを床等の水平面に載置した際には、床等の水平面と水平底部６との間には、所望の間隙が形成されるように構成されている。上記の周壁部材１を構成する内周壁部１ｃと載置部２と垂直壁３とにより、平面形状が額縁状の環状土手部７が形成されている。
【００１０】
平面形状が額縁状の環状土手部７には、環状土手部７の長手方向に対して垂直で、且つ、環状土手部７の幅Ｗ１と同じ長さ（環状土手部７の長手方向に対して垂直方向の長さ）Ｌ１を有する適当数の水平凹部８が形成されている。本実施例においては、環状土手部７の各辺に、所定の間隔を置いて、２個の水平凹部８が形成されている。水平凹部８の底部８ａは、水平部４までは達することはなく、環状土手部７を構成する載置部２と水平部４との中間に位置している。水平凹部８は、環状土手部７の各辺の中心に対して、対称に形成されていることが好ましい。水平凹部８は、環状土手部７を弾性変形し易くする機能を有するものであり、水平凹部８の深さ及び環状土手部７の長さ方向に沿った幅Ｗ２を、適宜、調整整することにより、環状土手部７の弾性変形の程度を、適宜、調整することができるように構成されている。
【００１１】
次に、図３について説明する。９ａは、周壁部材１を構成する外周壁部１ａの一方の相対する辺１ａ１に、所定の間隔を置いて形成された一対の外周壁部側凹部であり、外周壁部側凹部９ａは、外周壁部１ａを、内周壁部１ｃ方向に凹ますことにより形成されている。また、周壁部材１を構成する底部１ｂにも、底部１ｂを上方に膨出させることにより、外周壁部側凹部９ａに連続する底部側凹部９ｂが形成されており、外周壁部１ａに形成された外周壁部側凹部９ａと底部１ｂに形成された底部側凹部９ｂとにより、緊諦紐や緊諦バンド等の緊諦部材Ｂが挿入される緊諦部材用凹部９が形成されている。本実施例には、外周壁部１ａの一方の相対する辺１ａ１に、緊諦部材用凹部９を構成する外周壁部側凹部９ａが形成された例が示されているが、必要に応じて、外周壁部１ａのもう一方の相対する辺１ａ２に、外周壁部側凹部９ａを形成することもできるし、各辺１ａ１、１ａ２に、３個以上の緊諦部材用凹部９を形成することもできる。緊諦部材用凹部９は、上述した環状土手部７に形成された水平凹部８と相対するようには形成されておらず、緊諦部材用凹部９と水平凹部８とは、環状土手部７の長手方向にずれて形成されている。また、緊諦部材用凹部９は、水平凹部８より、環状土手部７の長手方向に対して外側に位置するように構成されている。
【００１２】
次に、図４について説明する。１０は、緊諦部材用凹部９が位置する周壁部材１を構成する外周壁部１ａと、緊諦部材用凹部９と対向する位置にある、同じく周壁部材１を構成する内周壁部１ｃとを連結する架橋リブであり、架橋リブ１０は、周壁部材１を構成する底部１ｂに連結されていてもよく、また、架橋リブ１０は、載置部２を越えて上方に延在しないように構成されている。
【００１３】
次に、主として、図５を用いて、上述した構成を有する梱包用トレーを用いて、物品Ａを梱包する手段について説明する。
【００１４】
先ず最初に、物品Ａを載置部２に載置するが、この際、物品Ａの底部付近の側面が、周壁部材１を構成する外周壁部１ａの内側に位置するとともに、好ましくは、物品Ａの底部付近の側面が、周壁部材１を構成する外周壁部１ａに近接或いは当接するようにする。また、物品Ａの上部に、図示されてないカバーを載置するが、このカバーは、上述した構成を有する梱包用トレーでもよく、この場合には、梱包用トレーを逆さにして載置する。次いで、緊諦紐や緊諦バンド等の緊諦部材Ｂが、緊諦部材用凹部９を構成する外周壁部１ａに形成された外周壁部側凹部９ａと底部１ｂに形成された底部側凹部９ｂとに挿入されるように配置し、その後、周知のように、緊諦部材Ｂにより、梱包用トレー、物品Ａ及びカバーを、一緒に、緊諦する。このようにして、物品Ａを梱包した後に、梱包用トレー、物品Ａ及びカバーの全体を、熱収縮性フィルム等のフィルムで被覆する。勿論、梱包する前に、物品Ａのみを、熱収縮性フィルム等のフィルムで被覆し、梱包後のフィルムによる被覆を省略することもできる。また、上述したように、水平底部６が、周壁部材１を構成する底部１ｂより、上方に位置しており、梱包用トレーを床等の水平面に載置した際に、床等の水平面と水平底部６との間には、所望の間隙が形成されるように構成されているので、緊諦部材Ｂを、容易に、梱包用トレーの下方に挿通することができるので、梱包作業の作業性が向上する。
【００１５】
上述したように、本発明の梱包用トレーにおいては、物品Ａが載置される載置部２の外側に、外周壁部１ａ、底部１ｂ及び内周壁部１ｃとからなる上方が開放された断面形状が略Ｕ字状の周壁部材１が形成されているので、梱包用トレーのコーナーの強度が大きく、従って、コーナーから落下しても、梱包用トレーのコーナーが損傷するようなことがなく、しかも、梱包用トレーは、底部１ｂを介して、外周壁部１ａと内周壁部１ｃとの二重構造に構成されているので、梱包用トレーに加わる衝撃を、確実に、吸収緩和することができる。
【００１６】
梱包用トレーのコーナーに加わった衝撃は、周壁部材１を構成する内周壁部１ｃと載置部２と垂直壁３とにより構成される環状土手部７に伝わることになるが、環状土手部７には、適当数の水平凹部８が形成されており、従って、環状土手部７は、このような水平凹部８が形成されていない場合に比べて、より弾力変形し易いので、梱包用トレーのコーナーに加わった衝撃を、より確実に、吸収緩和することができる。
【００１７】
緊諦部材用凹部９を形成したので、緊諦部材Ｂの位置決めを、容易に、且つ、確実迅速に行うことができる。また、緊諦部材用凹部９が位置する周壁部材１を構成する外周壁部１ａと、緊諦部材用凹部９と対向する位置にある、同じく周壁部材１を構成する内周壁部１ｃとを連結する架橋リブ１０を形成したので、緊諦部材Ｂの締め付けにより、外周壁部１ａが変形して、梱包用トレーや梱包された物品Ａが損傷するようなことが防止できる。更に、緊諦部材用凹部９を、環状土手部７に形成された水平凹部８と相対するように配置せずに、緊諦部材用凹部９と水平凹部８とを、環状土手部７の長手方向にずらして配置するように構成することにより、環状土手部７に形成された水平凹部８による衝撃を、より確実に、吸収緩和することができる。更にまた、緊諦部材用凹部９を、水平凹部８より、環状土手部７の長手方向に対して外側に位置するように構成することにより、水平凹部８を、環状土手部７の角部ではなく、より各辺の中央寄りに配置することができ、従って、環状土手部７が弾力変形し易くなり、梱包用トレーのコーナーに加わった衝撃を、更に確実に、吸収緩和することができる。
【００１８】
底部側凹部９ｂを形成することなく、外周壁部１ａに形成された外周壁部側凹部９ａのみにより、緊諦部材用凹部９を構成することもできるが、底部側凹部９ｂを形成することにより、より確実に、緊諦部材Ｂの位置決めができるとともに、緊諦部材Ｂが、緊諦部材用凹部９から外れることを防止することができる。また、直接、見えない周壁部材１を構成する底部１ｂに、確実に、且つ、最適位置に、緊諦部材Ｂを掛けることができる。
【００１９】
周壁部材１を構成する外周壁部１ａが、物品Ａが載置される載置部２より高く構成されているので、梱包用トレーに載置された物品Ａの横方向への移動を抑制することができるとともに、梱包用トレーに載置された物品Ａの下部を保護することができる。
【００２０】
上述した実施例においては、周壁部材１を構成する外周壁部１ａの一方の相対する辺１ａ１側に位置する環状土手部７に形成された水平凹部８の幅Ｗ２と、外周壁部１ａのもう一方の相対する辺１ａ２側に位置する環状土手部７に形成された水平凹部８の幅Ｗ２が異なっているが、梱包用トレーに物品Ａを載置した際に、より多くの重量がかかる環状土手部７を構成する載置部２に形成される水平凹部８の幅Ｗ２を狭くして、物品Ａが載置される載置部２の載置面積を大きくすることが好ましい。このように構成することにより、物品Ａのより大きな部分を負担する載置部２の変形を防止することができ、従って、梱包用トレーの変形に起因する転倒や物品Ａの損傷等を防止することができる。
【００２１】
なお、上述した梱包用トレーは、合成樹脂で一体成形することが好ましく、更には、家電リサイクル法等により回収された合成樹脂で成形することが、低コストや省資源化の観点から、特に好ましい。また、上述した梱包用トレーは、送付先より回収し、何度も繰り返して使用することができるので、リサイクル性に優れている。
【００２２】

【００２３】
第１に発明によれば、物品が載置される載置部の外側に、外周壁部、底部、内周壁部とにより、断面形状が略Ｕ字状の周壁部材を形成したので、梱包用トレーがコーナーの強度がアップし、梱包用トレーのコーナーが損傷するようなことがなく、しかも、梱包用トレーが、外周壁部、底部、内周壁部とにより断面形状が略Ｕ字状に構成されているので、梱包用トレーに加わる衝撃を、確実に、吸収緩和することができる。

Furthermore, the horizontal concave portion 8 is formed at the corner of the annular bank portion 7 by configuring the concave member concave portion 9 so as to be positioned outside the horizontal concave portion 8 with respect to the longitudinal direction of the annular bank portion 7. Therefore, the annular bank portion 7 is easily elastically deformed, and the impact applied to the corner of the packaging tray can be absorbed and relaxed more reliably.
[0018]
Without forming the bottom-side concave portion 9b, it is possible to form the tightening member concave portion 9 only by the outer peripheral wall-side concave portion 9a formed in the outer peripheral wall portion 1a. However, by forming the bottom-side concave portion 9b, And the positioning of the elastic member B can be performed more reliably, and the elastic member B can be prevented from coming off the elastic member recess 9. Moreover, the elastic member B can be reliably and optimally hung on the bottom part 1b which comprises the surrounding wall member 1 which cannot be seen directly.
[0019]
Since the outer peripheral wall part 1a which comprises the surrounding wall member 1 is comprised higher than the mounting part 2 in which the articles | goods A are mounted, the movement to the horizontal direction of the articles | goods A mounted in the tray for packing is suppressed. In addition, the lower part of the article A placed on the packing tray can be protected.
[0020]
In the embodiment described above, the width W2 of the horizontal recess 8 formed in the annular bank portion 7 located on one side 1a1 of the outer peripheral wall portion 1a constituting the peripheral wall member 1, and the other end of the outer peripheral wall portion 1a. Although the width W2 of the horizontal recessed part 8 formed in the annular bank part 7 located in the one side 1a2 opposite side differs, the cyclic | annular form which requires more weight when the articles | goods A are mounted in the packaging tray It is preferable to reduce the width W2 of the horizontal recess 8 formed in the placement portion 2 constituting the bank portion 7 and increase the placement area of the placement portion 2 on which the article A is placed. By configuring in this way, it is possible to prevent the placement portion 2 that bears a larger part of the article A from being deformed, and thus prevent falls caused by the deformation of the packaging tray, damage to the article A, and the like. be able to.
[0021]
The packaging tray described above is preferably integrally molded with a synthetic resin, and more preferably molded with a synthetic resin collected by the Home Appliance Recycling Law from the viewpoint of low cost and resource saving. . Moreover, since the packaging tray described above can be collected from the destination and used repeatedly over and over, it is excellent in recyclability.
[0022]
【The invention's effect】
Since this invention has the structure demonstrated above, there exists an effect described below.
[0023]
1st invention WHEREIN: Since the outer peripheral wall part, the bottom part, and the inner peripheral wall part formed the outer peripheral wall member in which cross-sectional shape is substantially U-shaped in the outer side of the mounting part in which articles | goods are mounted, for packing The strength of the tray is improved, the corner of the packaging tray is not damaged, and the packaging tray has a substantially U-shaped cross section with the outer peripheral wall, bottom, and inner peripheral wall. Therefore, the shock applied to the packaging tray can be reliably absorbed and reduced.
[0024]
According to the second invention, since an appropriate number of recesses are formed in the annular bank portion, the annular bank portion is easily elastically deformed, and therefore, the impact applied to the corner of the packaging tray can be absorbed more reliably. Can be relaxed.
[0025]
According to the third invention, since the concave member concave portion is formed in the peripheral wall member, the positioning of the elastic member can be performed easily and surely and quickly.
[0026]
According to the fourth aspect of the invention, the outer peripheral wall portion constituting the peripheral wall member in which the concave portion for the tightening member is located and the inner peripheral wall portion constituting the peripheral wall member at the position facing the concave portion for the tightening member are connected. Since the bridging rib to be formed is formed, it is possible to prevent the outer peripheral wall portion from being deformed by the tightening of the fastening member, and the packing tray or the packed article can be prevented from being damaged.
[0027]
According to the fifth aspect of the present invention, since the concave portion for the elastic member and the concave portion formed in the annular bank portion are shifted in the longitudinal direction of the annular bank portion, the impact caused by the concave portion formed in the annular bank portion is Absorption can be relaxed more reliably.
[0028]
According to the sixth invention, the concave portion for the elastic member is constituted by the outer peripheral wall portion-side concave portion formed in the outer peripheral wall portion constituting the peripheral wall member and the bottom portion-side concave portion formed in the bottom portion constituting the peripheral wall member. Therefore, the positioning of the tightening member can be more reliably performed, and the tightening member can be prevented from coming off from the concave portion for the tightening member, and directly on the bottom part constituting the invisible peripheral wall member, The tightening member can be reliably and optimally hung.
