Abstract

PROBLEM TO BE SOLVED: To provide a wrapping bag for sterilization which reliably detects seal defect.SOLUTION: The wrapping bag for sterilization is for wrapping a wrapped object, such as medical instruments, which needs sterilization, such as an injection, uses a transparent flexible sheet 11 having gas barrier and a sterilization sheet 13 of prescribed width having gas transmission and bacteria barrier and performs bag manufacturing while wrapping a wrapped object. An inner surface on both end edges in the width direction of the flexible sheet 11 is heat-sealed on an outer surface of both end edges in the width direction of the sterilization sheet 13, and the flexible sheet 11 and the flexible sheet 11, and the flexible sheet 11 and the sterilization sheet 13 are heat-sealed at both end parts in the longitudinal direction. On both end edges in the width direction of the flexible sheet 11, seal defect detection display 12 where many slanting lines SL are printed on an inner surface side at regular intervals is performed and, when the end edge in the width direction of the flexible sheet 11 is partially folded toward the inner surface side, many of the slanting lines SL are changed into V shaped lines.

Description

この発明は、例えば、注射器やカテーテルのように、滅菌処理が必要な医療用器具を包装する滅菌用包装袋に関する。   The present invention relates to a sterilization packaging bag for packaging medical instruments that require sterilization, such as syringes and catheters.

この種の滅菌用包装袋としては、例えば、図９に示すようなものがある。この滅菌用包装袋５０は、同図に示すように、内面にシーラント層が積層された、ガスバリア性を有する柔軟性シート５１と、ヒートシール性、ガス透過性及び菌バリア性を有する所定幅の滅菌シート５２とから構成されており、図１０に示すように、医療用器具等の被包装体Ｇを収容した状態で、柔軟性シート５１の両側縁の内面が滅菌シート５２の両側縁の外面にヒートシールされていると共に、両端部において、柔軟性シート５１同士及び柔軟性シート５１と滅菌シート５２とがヒートシールされている。なお、図９における網掛け表示領域がヒートシール部分である。   An example of this type of sterilization packaging bag is shown in FIG. As shown in the figure, the sterilization packaging bag 50 includes a flexible sheet 51 having a gas barrier property with a sealant layer laminated on the inner surface, and a predetermined width having a heat seal property, a gas permeability property, and a bacteria barrier property. As shown in FIG. 10, the inner surface of both side edges of the flexible sheet 51 is the outer surface of both side edges of the sterilizing sheet 52 in a state in which a package G such as a medical instrument is accommodated. In addition, the flexible sheets 51 and the flexible sheet 51 and the sterilized sheet 52 are heat sealed at both ends. The shaded display area in FIG. 9 is a heat seal portion.

従って、この滅菌用包装袋５０によって被包装体である医療用器具等を包装した状態で、過酸化水素ガス等を用いたガス滅菌や蒸気滅菌等の滅菌処理を施すと、滅菌シート５２を通って滅菌ガス等が袋内に侵入し、侵入した滅菌ガス等によって袋内が滅菌処理されるようになっている。なお、滅菌シート５２は、菌バリア性を有しているので、医療用器具等を包装した後に菌が袋内に侵入することはなく、袋内が滅菌処理された状態に保持される。   Therefore, when a sterilization process such as gas sterilization using hydrogen peroxide gas or steam sterilization is performed in a state in which a medical instrument or the like as a package is packaged in the sterilization packaging bag 50, the sterilization sheet 52 passes through. As a result, sterilization gas or the like enters the bag, and the bag is sterilized by the sterilization gas or the like that has entered. In addition, since the sterilization sheet 52 has a bacteria barrier property, the bacteria do not enter the bag after packaging a medical instrument or the like, and the bag is held in a sterilized state.

特開２００３−２９９７１７号公報JP 2003-299717 A

ところで、柔軟性シート５１の両側縁の内面を滅菌シート５２の両側縁の外面にヒートシールする際、何らかの要因で、図１１に示すように、柔軟性シート５１の側縁が部分的に内面側に折れ込んでしまうことがあるが、そのようにして折れ込んだ柔軟性シート５１の側縁部分は、ヒートシール性を有していない外面が滅菌シート５２の外面に接触することになるので、その部分はヒートシールされることがなく、袋全体として菌バリア性を確保することができなくなる。   By the way, when heat sealing the inner surfaces of both side edges of the flexible sheet 51 to the outer surfaces of both side edges of the sterilization sheet 52, as shown in FIG. However, the side edge portion of the flexible sheet 51 folded in such a manner is such that the outer surface that does not have heat sealability comes into contact with the outer surface of the sterilization sheet 52. The portion is not heat-sealed, and the bacteria barrier property cannot be ensured as the whole bag.

従って、こういったシール不良が発生した滅菌用包装袋に医療器具等の被包装体が収容された不良品は、目視や撮像手段を有する検査器等で検出して分別除去する必要があるが、上述したガスバリア性を有する柔軟性シート５１は、通常、透明であり、しかも、ヒートシール性を有していない柔軟性シート５１の外面と滅菌シート５２の外面とは熱によって擬似接着するので、シール不良を検出しにくく、不良品を確実に分別除去することができないといった問題がある。   Therefore, a defective product in which a packaged body such as a medical instrument is accommodated in a sterilization packaging bag in which such a sealing failure has occurred needs to be detected and separated by visual inspection or an inspection device having an imaging means. The flexible sheet 51 having gas barrier properties described above is usually transparent, and the outer surface of the flexible sheet 51 that does not have heat sealability and the outer surface of the sterilized sheet 52 are pseudo-bonded by heat. There is a problem that it is difficult to detect a sealing failure and the defective product cannot be reliably separated and removed.

そこで、この発明の課題は、シール不良を確実に検出することができる滅菌用包装袋を提供することにある。   Then, the subject of this invention is providing the packaging bag for sterilization which can detect a sealing defect reliably.

上記の課題を解決するため、請求項１に係る発明は、ガスバリア性を有する柔軟性シートに、ガス透過性及び菌バリア性を有する滅菌シートを部分的に接合してなる包材によって形成された滅菌用包装袋であって、前記柔軟性シートの端縁内面が前記滅菌シートの外面にヒートシールされており、前記滅菌紙にヒートシールされる前記柔軟性シートの端縁部分には、その端縁部分が折れ込んだときに異なるデザインに変化するシール不良検出用表示を施したことを特徴とする滅菌用包装袋を提供するものである。   In order to solve the above problems, the invention according to claim 1 is formed by a packaging material in which a sterilized sheet having gas permeability and bacteria barrier properties is partially joined to a flexible sheet having gas barrier properties. In the sterilization packaging bag, the inner edge of the flexible sheet is heat sealed to the outer surface of the sterilized sheet, and the edge of the flexible sheet that is heat sealed to the sterilized paper The present invention provides a sterilization packaging bag provided with a seal failure detection display that changes to a different design when the edge portion is folded.

以上のように、請求項１に係る発明の滅菌用包装袋は、滅菌シートにヒートシールされる柔軟性シートの端縁部分に、その端縁部分が折れ込んだときに異なるデザインに変化するシール不良検出用表示を施しているので、柔軟性シートの端縁部分のデザインの変化を目視または検出器等によって検出することで、シール不良が発生しているか否かを確実に把握することができる。   As described above, the sterilization packaging bag according to the first aspect of the present invention is a seal that changes to a different design when the edge portion is folded into the edge portion of the flexible sheet that is heat sealed to the sterilization sheet. Since the display for defect detection is provided, it is possible to reliably grasp whether or not a seal defect has occurred by detecting a change in the design of the edge portion of the flexible sheet visually or by a detector. .

以下、実施の形態について図面を参照して説明する。図１は、この発明に係る滅菌用包装袋１を示している。この滅菌用包装袋１は、注射器、カテーテル等の滅菌処理が必要な医療用器具等（以下、被包装体と言う。）を包装するものであり、ピロー包装機により、被包装体を包材によって包み込みながら製袋される。   Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a sterilization packaging bag 1 according to the present invention. This sterilization packaging bag 1 is used for packaging medical instruments that require sterilization treatment such as syringes and catheters (hereinafter referred to as a packaged body), and the packaged body is packaged by a pillow packaging machine. The bag is made while wrapping.

前記包材は、図１及び図２（ａ）、（ｂ）に示すように、ガスバリア性を有する透明な柔軟性シート１１と、ガス透過性及び菌バリア性を有する所定幅の滅菌シート１３とから構成されており、柔軟性シート１１の幅方向の両端縁の内面が滅菌シート１３の幅方向の両端縁の外面にヒートシールされていると共に、長手方向の両端部において、柔軟性シート１１同士及び柔軟性シート１１と滅菌シート１３とがヒートシールされている。なお、図１における網掛け表示部分がヒートシール部分を示している。   As shown in FIGS. 1 and 2 (a) and 2 (b), the packaging material includes a transparent flexible sheet 11 having gas barrier properties, and a sterilized sheet 13 having a predetermined width having gas permeability and bacteria barrier properties. The inner surfaces of both end edges in the width direction of the flexible sheet 11 are heat-sealed to the outer surfaces of the both end edges in the width direction of the sterilization sheet 13, and the flexible sheets 11 are And the flexible sheet | seat 11 and the sterilization sheet | seat 13 are heat-sealed. The shaded display portion in FIG. 1 indicates the heat seal portion.

前記柔軟性シート１１は、図３に示すように、二軸延伸ポリプロピレンフィルム、二軸延伸ポリアミドフィルム、二軸延伸ポリエステルフィルム等の単層フィルム等からなる厚さ１０〜３０μｍ程度の基材層１１ａと、この基材層１１ａの内面側に積層されたエチレン・ビニルアルコールコポリマ（ＥＶＯＨ）からなる単層フィルムやＥＶＯＨとポリアミドとを共押出しした２層構造または３層構造のラミネートフィルムからなるガスバリア層１１ｂと、このガスバリア層１１ｂの内面側に積層された未延伸ポリエチレンフィルムや未延伸ポリプロピレンフィルム等からなる厚さ３０〜１５０μｍ程度のシーラント層１１ｃとから構成されており、図２（ｂ）に示すように、幅方向の両端縁には、内面側に多数の斜線ＳＬが一定間隔で印刷されたシール不良検出用表示１２が施されている。   As shown in FIG. 3, the flexible sheet 11 is a base layer 11a having a thickness of about 10 to 30 μm made of a single layer film such as a biaxially stretched polypropylene film, a biaxially stretched polyamide film, or a biaxially stretched polyester film. And a gas barrier layer comprising a single-layer film made of ethylene / vinyl alcohol copolymer (EVOH) laminated on the inner surface side of the base material layer 11a, or a laminate film having a two-layer structure or a three-layer structure in which EVOH and polyamide are coextruded 2b and a sealant layer 11c having a thickness of about 30 to 150 μm made of unstretched polyethylene film or unstretched polypropylene film laminated on the inner surface side of the gas barrier layer 11b, as shown in FIG. 2 (b). As shown in the figure, a large number of diagonal lines SL are printed at regular intervals on both edges in the width direction. In addition, a seal failure detection display 12 is provided.

前記滅菌シート１３は、ガス透過性及び菌バリア性を有していれば、その材質等にも特に限定されず、紙製、樹脂製等、種々市販のものを使用することができる。具体的には、例えば、高圧で紡糸された、０．５〜１０ミクロンの高密度ポリエチレン連続性極細長繊維をランダムに積層した後、これを熱と圧力だけでシート状にしたデュポン社製の タイベック（登録商標）等が挙げられる。   If the said sterilization sheet 13 has gas permeability and microbe barrier property, it will not specifically limit to the material etc., Various products, such as paper and resin, can be used. Specifically, for example, a high-density polyethylene continuous ultra-fine fiber of 0.5 to 10 microns spun at high pressure is randomly laminated, and then made into a sheet shape only by heat and pressure. Examples include Tyvek (registered trademark).

以上のように、この滅菌用包装袋１は、滅菌シート１３にヒートシールされる透明の柔軟性シート１１の端縁部分に、一定間隔で印刷された多数の斜線ＳＬからなるシール不良検出用表示１２が施されているので、柔軟性シート１１の幅方向の両側縁の内面を滅菌シート１３の幅方向の両端縁の外面にヒートシールする際、何らかの要因で、図４（ａ）、（ｂ）に示すように、柔軟性シート１１の幅方向の一方の端縁が部分的に内面側に折れ込んだ場合、柔軟性シート１１の端縁は、ヒートシール性に乏しい外面が滅菌シート１３の外面に接触することになるので、その部分はヒートシールされることがなく、袋全体として菌バリア性を確保することができなくなる。   As described above, the sterilization packaging bag 1 has a seal failure detection display composed of a large number of oblique lines SL printed at regular intervals on the edge portion of the transparent flexible sheet 11 heat-sealed to the sterilization sheet 13. 4 is applied to the outer surfaces of both edges in the width direction of the flexible sheet 11 to the outer surfaces of both edges in the width direction of the sterilization sheet 13, for some reason, FIG. ), When one edge in the width direction of the flexible sheet 11 is partially folded into the inner surface, the outer edge of the flexible sheet 11 has a poor heat-seal property. Since it comes into contact with the outer surface, the portion is not heat-sealed, and the bacteria barrier property cannot be secured as a whole bag.

しかしながら、同図（ｂ）に示すように、柔軟性シート１１の幅方向の一方の端縁が部分的に内面側に折り込まれると、同図（ａ）に示すように、シール不良検出用表示１２を形成している多数の斜線ＳＬが、逆「く」字状の線ＣＬに変化することになるので、このシール不良検出用表示１２のデザインの変化を目視または検出器等によって検出することで、シール不良が発生しているか否かを確実に把握することができ、シール不良が発生している滅菌用包装袋１を確実に分別除去することができる。   However, when one edge in the width direction of the flexible sheet 11 is partially folded to the inner surface side as shown in FIG. 4B, a seal failure detection display is shown as shown in FIG. Since many slant lines SL forming 12 change to an inverted “<”-shaped line CL, the design change of the seal failure detection display 12 is detected visually or by a detector or the like. Thus, it is possible to reliably grasp whether or not a seal failure has occurred, and the sterilization packaging bag 1 in which the seal failure has occurred can be reliably separated and removed.

図５及び図６はシール不良検出用表示の変形例を示している。図５に示すように、柔軟性シート１１における幅方向の両端縁の内面には、その先端に、赤色または黒色のように、白色に対して明確に区別することができる色彩の直線Ｌを印刷した後、その直線Ｌを覆うように所定幅で白色のベタ印刷ＢＷを施したシール不良検出用表示１２Ａを採用すると、柔軟性シート１１の幅方向の一方の端縁が部分的に内面側に折り込まれると、図６に示すように、その折り込まれた部分には、直線Ｌが全く表示されない領域ができるので、この直線Ｌの有無を目視または検出器等によって検出することで、シール不良が発生しているか否かを確実に把握することができ、シール不良が発生している滅菌用包装袋１を確実に分別除去することができる。   5 and 6 show a modification of the seal failure detection display. As shown in FIG. 5, a straight line L of a color that can be clearly distinguished from white, such as red or black, is printed on the inner surface of both end edges in the width direction of the flexible sheet 11. After that, when the seal failure detection display 12A having a solid white print BW with a predetermined width so as to cover the straight line L is adopted, one edge in the width direction of the flexible sheet 11 is partially on the inner surface side. When folded, as shown in FIG. 6, there is a region where the straight line L is not displayed at all in the folded portion. By detecting the presence or absence of the straight line L with the naked eye or by a detector or the like, there is a seal failure. Whether or not it has occurred can be ascertained reliably, and the sterilization packaging bag 1 in which a sealing failure has occurred can be reliably removed.

また、図７に示すシール不良検出用表示１２Ｂのように、柔軟性シート１１の幅方向に延びる多数の直線ＨＬを一定間隔で印刷した場合も、柔軟性シート１１の幅方向の一方の端縁が部分的に内面側に折り込まれると、図８に示すように、デザインが変化することになるが、直線ＨＬの長さが短くなるだけで、デザインが顕著に変化するわけではないので、上述した各実施形態のように、線の形状が変化したり、線が消えたりするといった大きな変化が起こるようなデザインにしておくことが望ましい。   Moreover, even when a large number of straight lines HL extending in the width direction of the flexible sheet 11 are printed at regular intervals as in the seal failure detection display 12B shown in FIG. 8 is partially folded on the inner surface side, the design changes as shown in FIG. 8, but the length of the straight line HL is shortened and the design does not change significantly. As in each of the embodiments described above, it is desirable that the design be such that a large change occurs such that the shape of the line changes or the line disappears.

なお、上述した各実施形態では、斜線ＳＬや直線Ｌを印刷したシール不良検出用表示１２、１２Ａを採用しているが、これに限定されるものではなく、柔軟性シート１１の幅方向の端縁が内面側に折り込まれることによって、異なるデザインに変化するものであれば、線以外に文字配列やイラスト等、種々のデザインを採用することができる。このとき、斜線ＳＬのようなシール不良検出用表示１２の場合は、折り込まれた表示部分が外面側から確認することができるように柔軟性シート１１が透明であることが好ましく、直線Ｌのようなシール不良検出用表示１２Ａの場合は、直線Ｌを目立たせるような色を背景色とするベタ印刷を柔軟性シート１１に施しておくか、或いは不透明のフィルムや金属箔等を柔軟性シート１１の一層に設けることにより、柔軟性シート１１を不透明にしておくことが好ましい。   In each of the above-described embodiments, the seal failure detection displays 12 and 12A printed with the oblique lines SL and the straight lines L are employed. However, the present invention is not limited to this, and the end of the flexible sheet 11 in the width direction is used. In addition to the lines, various designs such as character arrangements and illustrations can be adopted as long as the edges are folded into the inner surface to change into different designs. At this time, in the case of the seal failure detection display 12 such as the slanted line SL, the flexible sheet 11 is preferably transparent so that the folded display portion can be confirmed from the outer surface side. In the case of a display 12A for detecting a defective seal, the flexible sheet 11 is subjected to solid printing with a background color that makes the straight line L conspicuous, or an opaque film or metal foil is applied to the flexible sheet 11. It is preferable to make the flexible sheet 11 opaque by providing it in one layer.

また、上述した各実施形態では、３方シールタイプのピロー包装袋について説明したが、これに限定されるものではなく、平袋、サイドガセット袋、底ガセットを備える自立袋等についても本発明を適用することができる。   In each of the above-described embodiments, the three-side seal type pillow packaging bag has been described. However, the present invention is not limited thereto, and the present invention is also applied to a flat bag, a side gusset bag, a self-supporting bag having a bottom gusset, and the like. Can be applied.

また、上述した各実施形態では、滅菌シート１３を袋の長手方向に配設したが、これに限定されるものではなく、袋の幅方向に配設することも可能である。   Moreover, in each embodiment mentioned above, although the sterilization sheet | seat 13 was arrange | positioned in the longitudinal direction of a bag, it is not limited to this, It is also possible to arrange | position in the width direction of a bag.

本発明は、注射器やカテーテルのように、滅菌処理が必要な医療用器具を包装する場合に利用することができる。   The present invention can be used when packaging medical instruments that require sterilization treatment, such as syringes and catheters.
