本発明の請求項１に係る緩衝性を有する封筒は、外部袋体の内部に備えた２枚のシートが緩衝材として機能する構成となっている。該シートにはエキスパンドメタル状の切り込みを設けており、エキスパンドメタルの製造過程と同様、切り込みの方向に対して垂直方向に延伸する事によりシートは網目状となる。同時に該シート各部位の変形はシート厚み方向にも生じる為、結果的にシートは弾性を備えた緩衝材として機能するようになる。変形されたシートは元の形状に戻ろうとするため、延伸した状態を保つためには該シートをエキスパンドメタルのように塑性変形させるか、弾性変形状態のままで延伸する力を保つ必要がある。しかし緩衝材として機能させる為には、概ね弾性変形内に留めるのが望ましい。従って延伸する力を保っている必要性が生じる。
緩衝材として機能する前記シートは、一辺が外部袋体の開口端部に固着されていることに加え、その辺に対向する辺同士が固着されている。その際、該シートの切り込みは前記外部袋体の開口部と平行になっている。該シートの切り込みに垂直する方向の寸法が前記外部袋体の同方向の内寸より少なくなっている為、外部袋体いっぱいに収容される物品を挿入すると該シートは延伸させられる。さらに外部袋体の開口部を封緘すると該シートは延伸した状態を保持する事になる。従って封緘されている限りは、該シートが緩衝材として機能する形状を保つことになる。
封緘を解き、内部の物品を取り出すと、弾性変形していた該シートは延伸した状態を保持する力から解除され元の形状に復元する。該シートの厚み方向の変形もなくなり、元の厚さに戻ることになる。その結果、封筒はほぼ使用前の容積となるため、廃棄する場合でも必要容積を減少することができ、廃棄物としての容量の削減に寄与できる。
また本発明の緩衝性を有する封筒は、前記外部袋体および緩衝材として機能するシートの全てが紙で形成されている構成を採用しているので、使用後は分別することなく再資源化が可能である。 The envelope having cushioning properties according to claim 1 of the present invention is configured such that two sheets provided inside the outer bag function as cushioning materials. The sheet is provided with expanded metal-like cuts, and the sheet becomes mesh-like when stretched in a direction perpendicular to the direction of the cut, as in the process of producing expanded metal. At the same time, deformation of each part of the sheet also occurs in the sheet thickness direction, and as a result, the sheet functions as a cushioning material having elasticity. Since the deformed sheet tends to return to its original shape, in order to maintain the stretched state, it is necessary to plastically deform the sheet like an expanded metal or to maintain a stretching force in an elastically deformed state. However, in order to function as a cushioning material, it is generally desirable to keep within elastic deformation. Therefore, it is necessary to maintain the drawing force.
The sheet functioning as a cushioning material has one side fixed to the open end of the external bag body, and the sides opposite to the side are fixed. In that case, the cut | notch of this sheet | seat is parallel to the opening part of the said external bag body. Since the dimension in the direction perpendicular to the notch of the sheet is smaller than the inner dimension in the same direction of the outer bag, the sheet is stretched when an article accommodated in the outer bag is inserted. Further, when the opening of the external bag is sealed, the sheet is held in the stretched state. Therefore, as long as the sheet is sealed, the sheet functions as a cushioning material.
When the seal is released and the article inside is taken out, the elastically deformed sheet is released from the force that holds the stretched state and is restored to its original shape. The deformation in the thickness direction of the sheet is eliminated and the original thickness is restored. As a result, since the envelope has almost the volume before use, the required volume can be reduced even when discarded, which can contribute to the reduction of the capacity as waste.
Moreover, since the envelope which has buffer property of this invention employ | adopts the structure by which all of the sheet | seat which functions as the said external bag body and a buffer material is formed of paper, it can recycle without separating after use. Is possible.
緩衝材として機能する前記シートは、一辺が外部袋体の開口端部に固着されていることに加え、その辺に対向する辺同士が固着されている。その際、該シートの切り込みは前記外部袋体の開口部と平行になっている。該シートの切り込みに垂直する方向の寸法が前記外部袋体の同方向の内寸より少なくなっている為、外部袋体いっぱいに収容される物品を挿入すると該シートは延伸させられる。さらに外部袋体の開口部を封緘すると該シートは延伸した状態を保持する事になる。従って封緘されている限りは、該シートが緩衝材として機能する形状を保つことになる。
封緘を解き、内部の物品を取り出すと、弾性変形していた該シートは延伸した状態を保持する力から解除され元の形状に復元する。該シートの厚み方向の変形もなくなり、元の厚さに戻ることになる。その結果、封筒はほぼ使用前の容積となるため、廃棄する場合でも必要容積を減少することができ、廃棄物としての容量の削減に寄与できる。
また本発明の緩衝性を有する封筒は、前記外部袋体および緩衝材として機能するシートの全てが紙で形成されている構成を採用しているので、使用後は分別することなく再資源化が可能である。 The envelope having cushioning properties according to claim 1 of the present invention is configured such that two sheets provided inside the outer bag function as cushioning materials. The sheet is provided with expanded metal-like cuts, and the sheet becomes mesh-like when stretched in a direction perpendicular to the direction of the cut, as in the process of producing expanded metal. At the same time, deformation of each part of the sheet also occurs in the sheet thickness direction, and as a result, the sheet functions as a cushioning material having elasticity. Since the deformed sheet tends to return to its original shape, in order to maintain the stretched state, it is necessary to plastically deform the sheet like an expanded metal or to maintain a stretching force in an elastically deformed state. However, in order to function as a cushioning material, it is generally desirable to keep within elastic deformation. Therefore, it is necessary to maintain the drawing force.
The sheet functioning as a cushioning material has one side fixed to the open end of the external bag body, and the sides opposite to the side are fixed. In that case, the cut | notch of this sheet | seat is parallel to the opening part of the said external bag body. Since the dimension in the direction perpendicular to the notch of the sheet is smaller than the inner dimension in the same direction of the outer bag, the sheet is stretched when an article accommodated in the outer bag is inserted. Further, when the opening of the external bag is sealed, the sheet is held in the stretched state. Therefore, as long as the sheet is sealed, the sheet functions as a cushioning material.
When the seal is released and the article inside is taken out, the elastically deformed sheet is released from the force that holds the stretched state and is restored to its original shape. The deformation in the thickness direction of the sheet is eliminated and the original thickness is restored. As a result, since the envelope has almost the volume before use, the required volume can be reduced even when discarded, which can contribute to the reduction of the capacity as waste.
Moreover, since the envelope which has buffer property of this invention employ | adopts the structure by which all of the sheet | seat which functions as the said external bag body and a buffer material is formed of paper, it can recycle without separating after use. Is possible.
本発明の請求項２に係る緩衝性を有する封筒は、前記外部袋体および緩衝材として機能するシートの両方もしくは一方を樹脂シートで形成している構成を採用している。例えば防水性や耐湿性を必要とする場合、あるいは開封する事なく内容物を透過して確認する必要性がある場合、これらの性能を付加できる。また、外部袋体とシートを同一の樹脂で形成すれば、この場合も分別することなく廃棄が可能である。
The envelope having cushioning properties according to claim 2 of the present invention adopts a configuration in which both or one of the outer bag and the sheet functioning as a cushioning material is formed of a resin sheet. For example, when waterproofness and moisture resistance are required, or when there is a need to confirm the contents through without opening, these performances can be added. Further, if the outer bag and the sheet are formed of the same resin, it can be discarded without separation in this case.
本発明の請求項３に係る緩衝性を有する封筒は、前記外部袋体および緩衝材として機能する２枚のシートに加え、内部に少なくとも１枚の紙または樹脂により形成された台紙が挿入されている。該台紙は外部袋体の内部に完全に収納できる寸法であるが、前記シートの切り込みに垂直する方向の寸法がシートの同方向の寸法より大きくなってなっている。前記シートを緩衝材として機能させるには、２枚のシートが互いに固着されている部分を押してシートを延伸する必要がある。しかし外部袋体に比較してかなり小さい物品を収容する場合などは、物品の代わりにこの台紙が前記２枚のシートの固着部を押す事によりシートを延伸させ、緩衝性を有する封筒として機能するようになる。
In the envelope having cushioning properties according to claim 3 of the present invention, in addition to the two sheets functioning as the outer bag body and the cushioning material, at least one sheet of paper or a mount made of resin is inserted therein. Yes. The mount is of a size that can be completely accommodated in the outer bag, but the size in the direction perpendicular to the sheet notch is larger than the size in the same direction of the sheet. In order for the sheet to function as a cushioning material, it is necessary to stretch the sheet by pressing a portion where the two sheets are fixed to each other. However, when an article that is considerably smaller than the external bag is accommodated, the mount extends the sheet by pushing the fixing portion of the two sheets instead of the article, and functions as an envelope having a cushioning property. It becomes like this.
本発明の請求項４に係わる緩衝性を有する封筒は、前記の台紙が２枚以上挿入されている場合、その台紙同士が外部袋体の開口側の辺を除く他の３辺の少なくとも１辺を固着している構成となっている。物品を収納する際、台紙と台紙の間に挟むことになるが、台紙同士が固着されていることにより、外部袋体に押し込む作業が容易になる。また開口側の辺に関しては、物品を収容した後に固着できるようフラップを設けておいてもよい。
In the envelope having cushioning properties according to claim 4 of the present invention, when two or more of the mounts are inserted, the mounts are at least one side of the other three sides excluding the opening side of the external bag body. It is the structure which has adhered. When the articles are stored, they are sandwiched between the mounts, but the mounts are fixed to each other, so that the work of pushing into the external bag body is facilitated. Further, with respect to the side on the opening side, a flap may be provided so that it can be fixed after the article is accommodated.
第１実施形態
本発明の第１の実施形態を、図面を参照しながら説明する。図１は本実施形態に係る緩衝性を有する封筒１の概略構成図である。封筒１は、一端に挿入用開口を有し他端を固着し有底とした外部袋体２と、緩衝材として機能する２枚のシート３により構成される。またシート３には、開口端と平行するようにエキスパンドメタル状切り込み４が設けられている。また図２はシート３を前記切り込み４に垂直する方向に延伸した状態を示す。
図３は本実施形態の切断線Ｘ−Ｘにおける断面図である。前記シート３は一辺が外部袋体２の開口部端部５に固着されており、対向する辺６が互いに固着されている。シート３の前記切り込み４に垂直する方向の寸法Ｌは外部袋体２の同方向の寸法Ｌ２より少なくなっている。
図４は本実施形態において、物品７を外部袋体２の中に完全に挿入した状態の切断線Ｘ−Ｘにおける断面図である。シート３は延伸される事によりシート厚み方向にも変形を生じる。この変形によりシート３自体がアーチ状の突起が連立する形状となり、厚み方向からの加重に対して弾性を備えた緩衝材として機能するようになる。
前記した実施形態では、外部袋体２と、緩衝材として機能する２枚のシート３を固着することにより、緩衝性を有する袋体１を構成しているが、例えば辺６で固着されている２枚のシート３は予め一体として形成してもよく、さらに開口部端部５で固着されている外部袋体２と、緩衝材として機能する２枚のシート３を予め一体として形成しておいても良い。図５は本発明の緩衝性を有する封筒１を単一のシートから形成する場合における概略構成図である。さらに外部袋体２には封緘用フラップ８が設けてあることが望ましいが、このフラップ８、もしくは外部袋体２本体のフラップ８と固着するべき箇所に接着テープ９を予め貼付しておいても良い。
第２実施形態
図６を用いて本発明の第２の実施形態の緩衝性を有する封筒１を、図面を参照しながら説明する。図６は封筒１に台紙１０を挿入した状態の概略構成図である。台紙１０は外部袋体２内部に完全に収納できる寸法であるが、シート３の切り込み４に垂直する方向の寸法Ｌより同方向の寸法Ｌ３が大きくなっている。よってシート３を延伸していない状態では、台紙１０が外部袋体２から一部はみだした状態となっている。図６で示すように、外部袋体２に比較してかなり小さい物品７を収容する場合などは、この台紙１０を外部袋体２に完全に収納するとシート３が変形され緩衝材として機能するようになる。また、台紙１０はシート３と辺６の部分で固着されていても良い。
第３実施形態
