Description

本発明は、電子部品や日用品、その他の物品を収納して保管や運搬、或いは展示などに供するのに好適な合成樹脂薄板の真空成形体よりなる収納トレーに関する。   The present invention relates to a storage tray made of a synthetic resin thin plate vacuum molded article suitable for storing electronic parts, daily necessities, and other articles for storage, transportation, or exhibition.

例えば電子部品などの生産工程で使用される収納トレー１００として、図２３に示されるように、縦横のリブ１０２で仕切られた物品収納部１０１の周囲が外周リブ１０３で囲われ、この外周リブ１０３を、当該リブの上面１０３ａの幅がその下端開口部の幅よりも幅広となる逆テーパ状の断面形状に設けて形成されており、収納トレー１００を上下に重ねた際に、上段の収納トレー１００の外周リブ１０３の下端部が下段の収納トレー１００の外周リブ１０３の上面に当接することで外周リブ１０３の没入を防止し、収納トレー１００、１００同士を上下多段に積み重ねることができるように構成されたものが知られている（例えば特許文献１、２、３参照）。   For example, as a storage tray 100 used in a production process of electronic parts or the like, as shown in FIG. 23, the periphery of an article storage unit 101 partitioned by vertical and horizontal ribs 102 is surrounded by an outer peripheral rib 103. Is formed in a reverse tapered cross-sectional shape in which the width of the upper surface 103a of the rib is wider than the width of the lower end opening, and when the storage tray 100 is stacked up and down, the upper storage tray The lower end of the outer peripheral rib 103 of the 100 abuts the upper surface of the outer peripheral rib 103 of the lower storage tray 100 so that the outer peripheral rib 103 can be prevented from being immersed, and the storage trays 100, 100 can be stacked in multiple stages. What was comprised is known (for example, refer patent documents 1, 2, and 3).

ところで、電子部品などの生産工程において、収納トレーを同方向に向けて積み重ねることができれば、収納作業における人為的ミスが生じ難く、収納トレーに電子部品の向きを揃えて収納し保管や運搬に供することが可能である。
前記図２３に示された収納トレー１００は、収納トレー１００同士を同方向に向けて積み重ねることができるものの、収納する電子部品が重量物である場合や収納トレー１００を多段に積み重ね過ぎた場合には、同図（Ｃ）に示されるように、上段の収納トレー１００から受ける下向きの荷重によって外周リブ１０３の縁辺部が外側へ逃げる如く広がって変形してしまい易いという問題があった。
電子部品を含む各種物品の運搬に用いられるこの種の収納トレーは、軽量化や材料費削減の要請から合成樹脂材料の薄肉化を図るべく開発が進められているが、合成樹脂材を薄くすると強度が低下することから、薄肉であっても強度を維持できる構造が望まれる。前記逆テーパ状の外周リブ１０３の傾斜角度を大きく確保できれば強度は高まるが、それでは成型金型のコストが高くなってしまう。 By the way, if the storage trays can be stacked in the same direction in the production process of electronic parts and the like, human errors in the storage work are unlikely to occur, and the electronic parts are stored in the storage tray in the same direction for storage and transportation. It is possible.
The storage tray 100 shown in FIG. 23 can stack the storage trays 100 in the same direction, but when the electronic components to be stored are heavy or when the storage trays 100 are stacked in multiple stages. As shown in FIG. 5C, there is a problem that the edge of the outer peripheral rib 103 is likely to spread and deform due to a downward load received from the upper storage tray 100 so as to escape to the outside.
This type of storage tray used for transporting various items including electronic parts is being developed to reduce the thickness of synthetic resin materials due to demands for weight reduction and material cost reduction. Since the strength is lowered, a structure capable of maintaining the strength even if it is thin is desired. If the inclination angle of the reverse-tapered outer peripheral rib 103 can be ensured to be large, the strength is increased, but this increases the cost of the molding die.

本発明は従来技術の有するこのような問題点に鑑み、合成樹脂薄板の真空成形体からなる収納トレーにおいて、トレー全体を薄肉に成形しても所望の強度を維持して、物品を収納したトレーを同方向に向けて上下多段に積み重ねて保管や運搬などに供することができるようにすることを課題とする。   SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention is a storage tray made of a synthetic resin thin plate vacuum molded body, which maintains the desired strength even when the entire tray is molded thin, and stores articles. It is an object of the present invention to stack them in the upper and lower stages in the same direction so that they can be stored and transported.

前記課題を解決するため本発明は、物品収納部の周囲が、収納部から立ち上がって外方へ張り出した平坦部と平坦部から下向きに折れて斜め下方へ拡開した外壁部からなる側枠部で囲われてなる合成樹脂薄板の真空成形体よりなる収納トレーであって、前記側枠部に形成された複数のスタック部で同一方向に向けて重ねられた上段のトレーを下段のトレーが支持して上下に積み重ね可能に構成された収納トレーにおいて、
前記各スタック部は、側枠部の外面に形成された窪み部内に窪み部の底部から起立して前記平坦部に連なる細柱部が設けられているとともに、当該細柱部はその下部両側面に内方へ凹んだ凹面部をそれぞれ設けて形成された構成を有することを特徴とする。 In order to solve the above-mentioned problem, the present invention provides a side frame portion including a flat portion that rises from the storage portion and protrudes outward from the storage portion, and an outer wall portion that folds downward from the flat portion and expands obliquely downward. A storage tray made of a synthetic resin thin plate vacuum molded body surrounded by a lower tray that supports an upper tray stacked in the same direction by a plurality of stack portions formed on the side frame portion. In the storage tray that can be stacked up and down ,
Wherein each stack portion together with Hosohashira portion continuous to the flat portion stands up from the bottom of the recess in the recess portion formed on an outer surface of the side frame portions are provided, the Hosohashira portion lower sides thereof It has the structure formed by providing the concave part recessed inward in each, It is characterized by the above-mentioned.

前記構成の収納トレーによれば、収納トレー同士を同方向に向けて重ね合わせた状態で、下段のスタック部の細柱部の上端が、上段のスタック部の細柱部の下端に接合することで、上下の収納トレーを一定の間隔を保持して積み重ねることができる。
上下に重なったスタック部で接合する細柱部は、その下部両側面に凹面部がそれぞれ形成され、細柱部の両側面間の間隔がその上部よりも下部の方が小さくなるように設けてあるので、下段の細柱部の上端は上段の細柱部の細幅の下端部に当接して支持され、下段の細柱部が上段の細柱部内に没入し難くなっている。また、各スタック部に細柱部を設けることで側枠部が補強されて外側へ開き難くなり、段積みした収納トレーに大きな衝撃が加わったときは上下の細柱部が互いに上下端部を接合させたままトレーの外周方向に互いに滑ることで衝撃を吸収し、これにより側枠部が外側へ開いてしまうなどの変形を来し難くなる。 According to the storage tray having the above configuration, the upper ends of the thin column portions of the lower stack portion are joined to the lower ends of the thin column portions of the upper stack portion in a state where the storage trays are overlapped in the same direction. Thus, the upper and lower storage trays can be stacked while maintaining a certain interval.
The narrow pillars joined by the stacks that overlap each other are provided with concave parts on both sides of the lower part so that the distance between both sides of the fine pillars is smaller in the lower part than in the upper part. Therefore, the upper end of the lower fine column portion is supported by being in contact with the narrow lower end portion of the upper fine column portion, and the lower fine column portion is difficult to be immersed in the upper fine column portion. In addition, by providing the narrow column part in each stack part, the side frame part is reinforced and it is difficult to open to the outside, and when a large impact is applied to the stacked storage tray, the upper and lower fine column parts mutually connect the upper and lower ends. While being joined, the impact is absorbed by sliding on each other in the outer peripheral direction of the tray, thereby making it difficult for deformation such as the side frame portion to open outward.

前記構成の収納トレーにおいて、細柱部の下部両側面と窪み部の底部とがそれぞれテーパ部で連なり、両テーパ部の上方の細柱部の両側面に凹面部をそれぞれ設けて形成された構成を有することが好ましい。

It is preferable to have.
By connecting the lower both side surfaces of the narrow pillar part to the bottom part of the hollow part via the taper part, the concave surface part provided above both taper parts can be molded while ensuring an appropriate thickness, By providing tapered portions on both sides of the lower column, when the storage trays are stacked, the narrow columns of the lower storage tray are connected to each other along the lower surface of the upper storage tray. It is possible to accurately guide to the matching position.

また、前記構成の収納トレーにおいて、窪み部内に複数の細柱部が適宜な間隔を開けて設けられた構成を有することが好ましい。
窪み部内に細柱部を設けることによって側枠部の強度が増して外周に開き難くなるが、細柱部を複数本、少なくとも一対を適宜な間隔を開けて設ければ、収納トレーに重量物を載せた際に側枠部を作用する開く方向への応力に対し、各細柱部同士が相互に引き合うように作用して側枠部の開きを防止し、側枠部の強度をより高めることができる。 Further, the storage tray having the above-described configuration preferably has a configuration in which a plurality of fine column portions are provided at appropriate intervals in the recess portion.
By providing the narrow column in the recess, the strength of the side frame is increased and it is difficult to open it to the outer periphery. However, if multiple thin columns and at least one pair are provided at an appropriate interval, a heavy load is placed on the storage tray. Against the stress in the opening direction that acts on the side frame when it is placed, the narrow pillars act so as to attract each other to prevent the opening of the side frame, and further increase the strength of the side frame be able to.
