The bag 1 is composed of a pair of main body sheets 2 and a pair of side sheets 3, and has an article storage section 4 between the opposing sheet surfaces 2c of the main body sheets 2. Is the same as the bag 1 in FIG.
袋 1 は、 両主体シー 卜 2の端縁部 2 bに沿って両主体シー ト 2 どう しを互いに係脱させるこ とが可能なファスナ手段 9 が形 成されている。 図では、 ファスナ手段 9 を介して両主体シー ト 2 どう しが係合し、 袋 1 が閉じられている。  The bag 1 is formed with fastener means 9 capable of engaging and disengaging the two main body sheets 2 along the edge 2b of the two main body sheets 2. In the figure, the two main body sheets 2 are engaged with each other via the fastener means 9, and the bag 1 is closed.
袋 1 は、 それを複数積み重ねたときに、 両主体シー ト 2のシ — ト面 2 c どう しが互いに重な り合うだけで、 側部シー ト 3 の 露出状態を維持するこ とができるので、 袋 1 の通気性が奪われ て しまう こ とはない。 複数の袋 1 を積み重ねた状態で、 有機気 化薬品の雰囲気にさ らされた場合でも、 薬品が側部シー ト 3 を 通して袋 1 の内部に流入するこ とができる。 ファスナ手段 9 を 有するものは、 両主体シー ト 2 どう しを係脱させて、 収納部 4 に物品 5 を入れた り取り 出した りする こ とができるので、 袋 1 を繰り返し使用するこ とができる。 The bag 1 can maintain the exposed state of the side sheet 3 only when the sheet surfaces 2 c of the two main sheets 2 overlap each other when a plurality of the bags 1 are stacked. Therefore, the air permeability of the bag 1 is not lost. Even when multiple bags 1 are stacked and exposed to the atmosphere of organic vaporized chemicals, the chemicals can wrap side sheets 3 And can flow into the inside of bag 1. The one having the fastener means 9 allows the two main sheets 2 to be disengaged from each other so that the article 5 can be put in and taken out of the storage section 4, so that the bag 1 is used repeatedly. Can be.
両主体シー ト 2 は、 ポリエチレン、 ポリ プロ ピレン、 ポリエ ステル等の熱可塑性合成樹脂で形成されたプラスチックシー ト を使用するこ とができる。 側部シー ト 3は、 滅菌紙や商品名夕 ィベックで知られる熱可塑性合成繊維で形成された不織布を使 用するこ とができる。 両主体シー ト 2 と側部シー ト 3 との接合 には、 ヒ一 ト シ一ルゃソニックシール等の熱融着の技術を利用 するこ とができる。 熱融着の技術の他に、 ホッ トメル ト接着剤 を利用するこ ともできる。 収納部 4 には、 不織布で形成された 使い捨ての手術用ガウン、 手術用ズボン、 手術用手袋等の物品 を収納するこ とができる。  As the main body sheet 2, a plastic sheet formed of a thermoplastic synthetic resin such as polyethylene, polypropylene, or polyester can be used. The side sheet 3 may be made of sterilized paper or a non-woven fabric formed of thermoplastic synthetic fiber known under the trade name of Yvec. For joining the main body sheet 2 and the side sheet 3, a heat sealing technique such as a heat seal sonic seal can be used. In addition to the heat fusion technology, hot melt adhesives can also be used. The storage section 4 can store articles such as disposable surgical gowns, surgical pants, and surgical gloves formed of non-woven fabric.
不通気不透湿性シー ト と通気不透湿性シー ト とを互いに重ね 合わせてそれらシー トの周縁部を互いに接合した袋では、 通気 不透湿性シー トを容易に引き裂く こ とができないので、 袋から 物品を取出すときには、 不通気不透湿性シー ト と通気不透湿性 シー ト との接合部位でそれらシー ト どう しを剥離させなければ ならない。 シー ト どう しの接着強度にもよるが、 シー ト どう し を剥離させるには、 かな りの力を必要とするので、 物品の取り 出し操作に手間取るこ とがある。 本実施の形態の袋 1 では、 物 品 5 を取出すために両主体シー ト 2 と側部シ一 ト 3 との接合部 位でそれらシー ト 2 , 3 どう しを剥離させる必要はな く、 案内 切り欠き 8 を利用して両主体シー ト 2 を引き裂いた り、 フ ァス ナ手段 9 を利用して袋 1 を開けるこ とができるので、 物品 5の 取り出し操作が容易である。 本発明に係る物品収納袋によれば、 互いに重な り合う不通気 不透湿性の両主体シー 卜の周縁部の間に部分的に通気不透湿性 の側部シ一 卜 を配置しているので、 滅菌処理に際して、 物品を 収納した多数の袋を積み重ねたときであっても、 袋の通気性が 奪われることはな く、 効率的に滅菌処理するこ とができる。 A bag in which an air-impermeable and impermeable sheet and an air-impermeable and impervious sheet are overlapped with each other and the peripheries of the sheets are joined to each other cannot be easily torn. When removing an article from an air-impermeable sheet, the sheet must be peeled off at the joint between the air-impermeable sheet and the air-impermeable sheet. Although it depends on the adhesive strength between the sheets, peeling off the sheets requires a considerable amount of force, and it may take time to remove the articles. In the bag 1 of the present embodiment, it is not necessary to peel off the sheets 2 and 3 at the joint of the main body sheet 2 and the side sheet 3 in order to take out the article 5, Since the main body sheet 2 can be torn using the guide notch 8 and the bag 1 can be opened using the fastener means 9, the operation of taking out the article 5 is easy. ADVANTAGE OF THE INVENTION According to the goods storage bag which concerns on this invention, the air-permeable and moisture-impermeable side sheet | seat is arrange | positioned partially between the peripheral parts of the air-impermeable and moisture-permeable main body sheets which overlap mutually. Therefore, even when a large number of bags containing articles are stacked during sterilization, the bags can be efficiently sterilized without losing the air permeability of the bags.
