Description

本発明は、電子機器、精密機器などの内容物体を保護するバッグに関するものである。
The present invention relates to a bag for protecting content objects such as electronic equipment and precision equipment.

従来、パソコンなどの電子機器をバッグに入れて持ち運ぶ際、電子機器の荷重でバッグの生地がつぶされ、その個所で生地の反発弾性力を失う。そのため、その時点で外力が作用すると、電子機器に衝撃力が働き、電子機器を破損する恐れがある。
Conventionally, when carrying an electronic device such as a personal computer in a bag, the fabric of the bag is crushed by the load of the electronic device, and the rebound resilience of the fabric is lost at that location. Therefore, if an external force is applied at that time, an impact force is applied to the electronic device, and the electronic device may be damaged.

本発明は、内容物体を保護するバッグを提供することにある。
It is an object of the present invention to provide a bag that protects a content object.

＜イ＞本発明は、高反発弾性素材の層と低反発弾性素材の層の少なくとも２層を有する多層生地で形成され、内容物体を保護するバッグにある。
＜ロ＞また、本発明は、上記バッグにおいて、高反発弾性素材の層を外側に配し、低反発弾性素材の層を内側に配するバッグにある。
＜ハ＞また、本発明は、上記バッグにおいて、高反発弾性素材の層の厚さは２ｍｍ〜１０ｍｍとし、低反発弾性素材の層の厚さは４ｍｍ〜２０ｍｍとするバッグにある。
<A> The present invention is a bag which is formed of a multi-layer fabric having at least two layers of a high rebound resilience material layer and a low rebound resilience material layer, and protects a content object.
 Further, according to the present invention, in the above bag, the layer of the high resilience elastic material is arranged on the outside and the layer of the low resilience elastic material is arranged on the inside.
<C> Further, the present invention is the above bag, wherein the layer of the high repulsion elastic material has a thickness of 2 mm to 10 mm, and the layer of the low repulsion elastic material has a thickness of 4 mm to 20 mm.

以下、図面を用いて本発明の実施の形態を説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

＜イ＞バッグ
バッグは、電子機器、精密機器などの内容物体を収納し、内容物体にかかる衝撃などの力から保護するもので、高反発弾性素材の層と低反発弾性素材の層の少なくとも２層を有する多層生地で構成される。バッグは、ケース、かばん、容器、袋物など、内容物体を収納し、内容物体にかかる衝撃などから保護できるものであればよい。
<A> Bag The bag is used to store a content object such as an electronic device or a precision device and protect it from a force such as an impact applied to the content object. At least two layers of a high-repulsion elastic material layer and a low-repulsion elastic material layer are used. Consists of multi-layer fabric with layers. Any bag may be used as long as it can store a content object such as a case, a bag, a container, or a bag and protect it from an impact applied to the content object.

＜ロ＞多層生地
多層生地は、高反発弾性素材の層と低反発弾性素材の層の少なくとも２層を有する多層の生地である。多層生地２は、例えば図１に示すように、バッグ１の本体１１に使用される。低反発弾性素材の層２１と高反発弾性素材の層２２とは、相互にずれないように、接着、縫製などで一体化されているとよい。多層生地２は、デザインや保護のために必要に応じて、図１（Ｂ）に示すように、内生地（インナークロス）２３及び／又はナイロンクロスなどの外生地（表面クロス）２４で覆う。また、多層生地２は、図示していないが、他の素材の層を加えて、３層以上（内外の表面生地を除いて）にしてもよい。 Multilayer Fabric The multilayer fabric is a multilayer fabric having at least two layers of a high rebound resilience material layer and a low rebound resilience material layer. The multilayer fabric 2 is used for the main body 11 of the bag 1, for example, as shown in FIG. The layer 21 of the low rebound resilience material and the layer 22 of the high rebound resilience material are preferably integrated by adhesion, sewing, or the like so as not to be displaced from each other. The multilayer fabric 2 is covered with an inner fabric (inner cloth) 23 and / or an outer fabric (surface cloth) 24 such as a nylon cloth, as shown in FIG. Moreover, although the multilayer fabric 2 is not shown in the figure, it may be formed of three or more layers (excluding the inner and outer surface fabrics) by adding layers of other materials.

低反発弾性素材の層２１と高反発弾性素材の層２２は、バッグの内側又は外側のどちらに配しても良いが、好ましくは、高反発弾性素材の層２２を外側に配し、低反発弾性素材の層２１を内側に配するとよい。低反発弾性素材の層２１をバッグ１の内側に配すると、例えば内容物体の荷重などの力で内容物体の凸部がバッグの生地を外側に押し出す際、低反発弾性素材の層２１が潰れ、内容物体の凸部が低反発弾性素材の層２１に食い込み、低反発弾性素材が凸部全体を覆い、内容物体にかかる力を分散する。それと共に、高反発弾性素材の層２２は、弾性力が大きいので、内容物体の凸部が外側に押し出す力を阻止することができる。また、高反発弾性素材の層２２は、バッグ１の外からの外力が内容物体に作用する力を阻止することができる。このように、多層生地２をバッグ１に使用することにより、内容物体を保護することができる。 The layer 21 of the low resilience material and the layer 22 of the high resilience material may be arranged either on the inside or the outside of the bag, but preferably, the layer 22 of the high resilience material is arranged on the outside, It is preferable to arrange the elastic material layer 21 inside. When the layer 21 of the low-rebound resilience material is arranged inside the bag 1, for example, when the convex portion of the content object pushes the cloth of the bag outward by a force such as a load of the content object, the layer 21 of the low-rebound resilience material is crushed The convex part of the content object bites into the layer 21 of the low rebound resilience material, and the low rebound elastic material covers the whole convex part, and the force applied to the content object is dispersed. At the same time, the layer 22 of high resilience elastic material has a large elastic force, and therefore can prevent the force of the convex portion of the content object from pushing outward. Moreover, the layer 22 of the high rebound resilience material can prevent the force that the external force from the outside of the bag 1 acts on the content object. Thus, by using the multilayer fabric 2 for the bag 1, the content object can be protected.

それに対して、従来の主に低反発弾性素材の生地からなるバッグの場合、高反発弾性素材の層がないので、内容物体の荷重で低反発弾性素材の層が潰れきってしまい、バッグの生地の弾性力がなくなり、外力が作用すると、内容物体を破損する恐れがある。また、内容物体の凸部がバッグの生地を外側に押し出して突出し、外力が作用すると、内容物体を破損する恐れがある。このように、主に低反発弾性素材の生地からなるバッグの場合、内容物体の荷重によって低反発弾性素材の層がつぶれきってしまい、保護能力が著しく低下するが、本発明のように、多層生地２を使用すると、外側に高反発弾性素材の層２２があるので、低反発弾性素材の層２１がつぶれきった場合でも高反発弾性素材の層２２により保護力を高めることができる。
On the other hand, in the case of conventional bags made mainly of low-rebound elastic material, there is no layer of high-rebound elastic material, so the layer of low-rebound elastic material is completely crushed by the load of the content object, and the bag fabric If the elastic force is lost and an external force is applied, the content object may be damaged. Further, if the convex portion of the content object pushes out the cloth of the bag and protrudes and an external force acts, the content object may be damaged. In this way, in the case of a bag mainly made of low rebound elastic material cloth, the layer of the low rebound elastic material is crushed by the load of the content object, and the protective ability is remarkably reduced. When the fabric 2 is used, since the layer 22 of the high rebound resilience material is provided on the outside, the protective force can be enhanced by the layer 22 of the high rebound resilience material even when the layer 21 of the low rebound resilience material is completely crushed.

＜ハ＞低反発弾性素材の層
低反発弾性素材は、反発力の弱い素材であり、ＪＩＳＫ６４００に基づいて算出された反発弾性率が４０％以下のものを使用できる。好ましくは、反発弾性率が３０％以下のものがよい。低反発弾性素材は、ウレタンフォームなどで作られたもの、発泡剤、整泡剤、触媒などを混合し、樹脂化させながら発泡させたもので、気泡が連通し、柔らかくて復元性がある。低反発弾性素材は、内容物体の荷重などの外力で凹み、内容物体の凸部など一部の周囲を覆って保護するものである。反発力が強すぎると、内容物体に強い力が作用する恐れがある。低反発弾性素材の層２１の厚さは、２ｍｍ以上、特に４ｍｍ以上、２０ｍｍ以下が好ましい。あまり薄いと、内容物体にかかる力を十分に吸収することができなくなり、また、厚すぎるとバッグとして利便性に欠けるようになる。
<C> Layer of Low Rebound Elastic Material The low rebound elastic material is a material having a weak rebound force, and a material having a rebound elastic modulus calculated based on JIS K 6400 of 40% or less can be used. Preferably, the impact resilience is 30% or less. The low resilience material is made of urethane foam or the like, and is made by mixing a foaming agent, a foam stabilizer, a catalyst, etc., and foaming while making it into a resin. The low rebound resilience material is recessed by an external force such as a load of the content object, and covers and protects a part of the periphery such as the convex portion of the content object. If the repulsive force is too strong, a strong force may act on the content object. The thickness of the layer 21 of the low impact resilience material is preferably 2 mm or more, particularly 4 mm or more and 20 mm or less. If it is too thin, it will not be possible to sufficiently absorb the force applied to the content object, and if it is too thick, it will be inconvenient as a bag.

＜ニ＞高反発弾性素材の層
高反発弾性素材は、低反発弾性素材と比較して、ＪＩＳＫ６４００に基づいて算出された反発弾性率が５％以上、好ましくは１０％以上高いものを使用する。例えば、低反発弾性素材の反発弾性率が２０％の場合、高反発弾性素材の反発弾性率は、３０％以上のものを使用する。また、低反発弾性素材の反発弾性率が３０％の場合、高反発弾性素材の反発弾性率は、４０％以上のものを使用する。低反発弾性素材と高反発弾性素材の反発弾性率は、バックに入れられる内容物体の荷重や精密機器の種類などによって選択することができる。高反発弾性素材は、クロロプレンや軟質ゴム、発泡ウレタン、ゲル板、柔らかいビニール、シリコンなどの素材を使用できる。高反発弾性素材の層２２の厚さは、１ｍｍ以上、特に２ｍｍ以上、１０ｍｍ以下が好ましく、あまり薄いと、内容物体の一部にかかる力を十分に吸収することができなくなり、また、厚すぎるとバッグとして利便性に欠けるようになる。
<D> Layer of high rebound resilience material High rebound resilience material has a rebound resilience calculated based on JIS K 6400 of 5% or more, preferably 10% or more higher than that of low rebound resilience material To do. For example, when the rebound resilience of the low rebound resilience material is 20%, the rebound resilience of the high rebound resilience material is 30% or more. When the rebound resilience of the low rebound resilience material is 30%, the rebound resilience of the high rebound resilience material is 40% or more. The rebound resilience of the low rebound resilience material and the high rebound resilience material can be selected depending on the load of the content object placed in the bag, the type of precision instrument, and the like. As the high resilience material, materials such as chloroprene, soft rubber, urethane foam, gel plate, soft vinyl, and silicon can be used. The thickness of the layer 22 of the high resilience material is preferably 1 mm or more, particularly 2 mm or more and 10 mm or less, and if it is too thin, the force applied to a part of the content object cannot be absorbed sufficiently, and is too thick. And it will become inconvenient as a bag.
