Japanese Utility Model Publication No. 6-40127

しかしながら、これらにはいずれも問題があった。すなわち、上記（１）の方法では、梱包作業の負担が大きく、上記（２）の方法では、緩衝材自体の体積が大きいため、不使用時の保管や破棄時の負担が大きく、上記（３）の方法では、輸送中の振動により箱中の物品の位置に偏りが生じ、物品が箱の内面に直接接してしまい破損する恐れがあり、上記（４）の方法では、物品の大きさ、形状に合わせて緩衝ケースを形成しなければならないため、特定の形の物品しか梱包できず、様々な物品に対応するのは困難であった。 However, both of these have problems. That is, in the method (1), the burden of packing work is large, and in the method (2), the volume of the cushioning material itself is large, so the burden when storing or discarding when not in use is large. In the method of (4), the position of the article in the box is biased due to vibration during transportation, and the article may be in direct contact with the inner surface of the box and be damaged. In the method (4), the size of the article, Since the buffer case must be formed in accordance with the shape, only articles of a specific shape can be packed, and it was difficult to deal with various articles.

本発明は、かかる問題点に鑑みてなされたもので、精密機械等の衝撃に弱い物品を、輸送するための梱包緩衝材として、梱包作業が簡易で、保管・破棄時の負担が小さく、物品の形状にかかわらず、物品を衝撃から守る梱包緩衝材を提供するものである。 The present invention has been made in view of such problems, and as a packing cushioning material for transporting an article vulnerable to impact such as a precision machine, the packing work is simple, the burden at the time of storage and disposal is small, and the article. The present invention provides a packaging cushioning material that protects articles from impacts regardless of their shape.

本発明は、被梱包物を格納する内袋部と前記内袋部を覆う外袋部とからなり、前記内袋部と前記外袋部との間は気体が充填密封されて気体充填部を形成し、前記内袋部は前記被梱包物を密着保持することを特徴とする梱包緩衝材である。 The present invention comprises an inner bag portion for storing an object to be packed and an outer bag portion covering the inner bag portion, and a gas filling portion is provided between the inner bag portion and the outer bag portion so that gas is filled and sealed. It is formed, and the inner bag part is a packing cushioning material characterized in that the packed object is held tightly.

本発明の梱包緩衝材によれば、被梱包物は内袋部に密着され気体充填部により保持されているので、内部で被梱包物が偏ることがなく、外部から衝撃を受けても気体充填部が衝撃を吸収し、被梱包物を破損から守ることができる。また、梱包緩衝材の梱包作業は、気体充填前の柔軟な状態で被梱包物を内袋部の間に格納し、その後、気体を充填するのみであるため、作業負担が非常に少ない。更に、本発明の梱包緩衝材は、未使用時の気体を充填していない状態では、体積が小さく保管・破棄時の負担が少ない。又、本発明では、内袋部に収まるものであれば、形状にかかわらず安定して梱包することが可能である。 According to the packing cushioning material of the present invention, the packed object is closely attached to the inner bag part and is held by the gas filling part. The part absorbs the impact and can protect the packaged items from damage. In addition, the packing work of the packing cushioning material involves only storing the packed object between the inner bag portions in a flexible state before gas filling, and thereafter filling the gas, so that the work load is very small. Furthermore, the packing cushioning material of the present invention has a small volume and a small burden during storage / discarding when not filled with gas when not in use. Moreover, in this invention, as long as it can fit in an inner bag part, it can pack stably irrespective of a shape.

更に、外袋部をある程度剛性の高い材質とし、気体充填時に定型になるようにすれば、運搬時に更にケースに収納することなく、梱包緩衝材がケースを兼ねることができる。 Further, if the outer bag portion is made of a material having a certain degree of rigidity and becomes a fixed shape at the time of gas filling, the packing cushioning material can also serve as the case without being stored in the case at the time of transportation.

A resin film is preferable, and examples thereof include hard polyethylene, polystyrene, nylon, etc. having a thickness of 200 μm or more. In order to withstand external impacts, it is also effective to use paper that has a resin coating that is more rigid than the inner bag portions 5a and 5b and has lost air permeability, or paper that is bonded with aluminum foil. is there. Furthermore, by using a highly rigid material and forming an outer bag portion having a fixed shape when filled with gas, it can also serve as a case during transportation.

内袋保持部１３ａ、１３ｂは、内袋を保持するに必要な強度を有する材質で形成され、好ましくは樹脂フィルムであり、ポリエチレン、ポリスチレン等が好適に使用可能である。 The inner bag holding portions 13a and 13b are formed of a material having a strength necessary for holding the inner bag, preferably a resin film, and polyethylene, polystyrene, or the like can be suitably used.

外袋部３ａ、３ｂには、気体を充填するための気弁部１７ａ、１７ｂを設ける。気弁部１７ａ、１７ｂは逆止弁であることが作業上好ましい。 The outer bag portions 3a and 3b are provided with air valve portions 17a and 17b for filling gas. The air valve portions 17a and 17b are preferably check valves for work.

気体充填部１９ａ、１９ｂの厚さは、特に限定するものではないが、衝撃を吸収するに充分な厚み、例えば図２において、振動や衝突等により内袋部がゆらいだ際、内袋部が外袋部に接しないのに充分な厚みを設ける必要がある。 The thickness of the gas filling portions 19a and 19b is not particularly limited. However, when the inner bag portion fluctuates due to vibration or collision in FIG. It is necessary to provide a sufficient thickness so as not to contact the outer bag portion.

次に、梱包緩衝材１に被梱包物７を梱包する方法を説明する。
まず、図１に示す気体充填部に気体を充填しない状態で、内袋部５ａと５ｂの間に被梱包物７を格納し、図２及び図３に示すように、気体充填後に気体充填部１９ａと気体充填部１９ｂとが離れないように、留め具１６で外袋部３ａと外袋部３ｂとを留め、外周をバンド１５で固定する。次に、気弁部１７ａ、１７ｂよりそれぞれ気体を注入すると、内袋部５ａ、５ｂと外袋部３ａ、３ｂとの間が膨張して、内袋部５ａと５ｂの間の気体は開口部１１より排出され、内袋部５ａ、５ｂが被梱包物７に密着するとともに、気体充填部１９ａ、１９ｂを形成する。この際、被梱包物７は、内袋保持部１３ａ、１３ｂにより、梱包緩衝材１の中で偏ることなく保持され、気体充填部１９ａ、１９ｂに挟まれて保護される。 Next, a method for packing the article 7 to be packed in the packing cushioning material 1 will be described.
First, in a state where the gas filling portion shown in FIG. 1 is not filled with gas, the article 7 is stored between the inner bag portions 5a and 5b. As shown in FIGS. The outer bag portion 3 a and the outer bag portion 3 b are fastened with the fastener 16 so that the 19 a and the gas filling portion 19 b are not separated, and the outer periphery is fixed with the band 15. Next, when gas is injected from the air valve portions 17a and 17b, the space between the inner bag portions 5a and 5b and the outer bag portions 3a and 3b expands, and the gas between the inner bag portions 5a and 5b opens. 11 and the inner bag portions 5a and 5b are in close contact with the article 7 to be packed and gas filling portions 19a and 19b are formed. Under the present circumstances, the to-be-packaged object 7 is hold | maintained by the inner bag holding | maintenance part 13a, 13b, without being biased in the packing cushioning material 1, and is pinched | interposed and protected by the gas filling part 19a, 19b.

開梱に当たっては、気体充填部１９ａ、１９ｂ内の気体を排出させて開口部１１から被梱包物を取り出すことができる。また、バンド１５と留め具１６をはずし、気体充填部１９ａと気体充填部１９ｂとの境界部を分割することにより、容易に被梱包物を取り出すことが可能である。 In unpacking, the packaged item can be taken out from the opening 11 by discharging the gas in the gas filling portions 19a and 19b. Further, by removing the band 15 and the fastener 16 and dividing the boundary portion between the gas filling portion 19a and the gas filling portion 19b, it is possible to easily take out the object to be packed.

本実施の形態によれば、被梱包物７は内袋部５ａ、５ｂに密着され、気体充填部１９ａ、１９ｂにより保持されているので、内部で被梱包物７が偏ることがなく、外部から衝撃を受けても気体充填部１９ａ、１９ｂが衝撃を吸収し、被梱包物７を破損から守ることができる。 According to the present embodiment, the object to be packed 7 is in close contact with the inner bag parts 5a and 5b and is held by the gas filling parts 19a and 19b. Even if it receives an impact, the gas filling parts 19a and 19b can absorb the impact and protect the packaged item 7 from being damaged.

また、梱包緩衝材１の梱包作業は、気体充填前の柔軟な状態で被梱包物を内袋部５ａと５ｂとの間に格納し、その後、気弁部１７ａ、１７ｂから気体を充填するのみであるため、作業負担が非常に少ない。また、内袋部５ａ、５ｂが、気体の充填により被梱包物に密着して固定するので、被梱包物の形状にかかわらず、被梱包物を衝撃による破損から守ることができる。更に、本発明の梱包緩衝材１は、未使用時の気体を充填していない状態では、体積が小さく保管・破棄時の負担が少ない。更に、外袋部をある程度剛性の高い材質とし、気体充填時に定型になるようにすれば、運搬時に更にケースに収納することなく、梱包緩衝材がケースを兼ねることができる。 Moreover, the packing operation of the packing cushioning material 1 is only to store the packed object between the inner bag portions 5a and 5b in a flexible state before gas filling, and then fill the gas from the air valve portions 17a and 17b. Therefore, the work load is very small. Further, since the inner bag portions 5a and 5b are in close contact with and fixed to the packed object by gas filling, the packed object can be protected from damage due to impact regardless of the shape of the packed object. Furthermore, the packing cushioning material 1 of the present invention has a small volume and a small burden during storage / discarding in a state where the packing cushioning material 1 is not filled with gas when not in use. Further, if the outer bag portion is made of a material having a certain degree of rigidity and becomes a fixed shape at the time of gas filling, the packing cushioning material can also serve as the case without being stored in the case at the time of transportation.

なお、上記実施形態では、気体充填部は、二つに分割したが、三つ以上に分割することも好適である。この場合、それぞれの気体充填部は、独立して気体が充填密封されるよう、気体充填部に気弁部をそれぞれ設ける。複数に分割して構成することにより、１つの気体充填部が破損した場合、他の気体充填部により、緩衝材としての機能を維持することが可能となる。図４に、四つに分割した場合の実施形態に係る梱包緩衝材２１の斜視図を示す。四つの気体充填部を備え、それぞれに上記実施例と同様の気弁部２３を設ける。本実施形態においても、上記実施形態と同様に、被梱包物を格納し、テープ等の留め具２７とバンド２５を用いて外袋部を固定した後、気弁部２３より気体を充填し、気体充填部を形成させる。 In addition, in the said embodiment, although the gas filling part was divided | segmented into two, dividing | segmenting into three or more is also suitable. In this case, each gas filling part is provided with a gas valve part in the gas filling part so that the gas is filled and sealed independently. By dividing it into a plurality of parts, when one gas filling part is damaged, the function as a buffer material can be maintained by the other gas filling part. In FIG. 4, the perspective view of the packing cushioning material 21 which concerns on embodiment at the time of dividing | segmenting into four is shown. Four gas filling parts are provided, and each is provided with the same air valve part 23 as in the above embodiment. Also in the present embodiment, similar to the above-described embodiment, the packaged goods are stored, and after fixing the outer bag portion using the fasteners 27 such as tape and the band 25, the gas is filled from the air valve portion 23, A gas filling part is formed.
