Description
【０００１】[0001]
本考案は、使い捨て注射針又は人工心肺の使い捨て部品等のように無菌状態で ユーザーに供給される滅菌済み医療用具に対して、該医療用具を無菌状態に保持 するための包装用封止部に関するものである。 The present invention relates to a packaging sealing portion for maintaining a sterile condition of a sterilized medical device such as a disposable injection needle or a disposable part of a heart-lung machine which is aseptically supplied to a user. It is a thing.
【０００２】[0002]
滅菌済み医療用具にとって最も大切なことは、該医療用具が確実に滅菌されて いることであり、該医療用具の包装体にとって最も大切なことは、滅菌されて無 菌状態にされている該医療用具の無菌状態を該医療用具の使用時まで確実に保持 することである。 The most important thing for a sterilized medical device is that the medical device is definitely sterilized, and the most important thing for a package of the medical device is that the medical device is sterilized and sterilized. To ensure that the sterile condition of the device is maintained until the medical device is used.
【０００３】 滅菌済み医療用具の包装体の従来の実施の一例は、図１３，図１４に示されて おり、滅菌済み医療用具の代表的製品であるディスポーザブル・シリンジｂの包 装体ａである。An example of a conventional implementation of a sterilized medical device package is shown in FIGS. 13 and 14, and is a package a of a disposable syringe b that is a typical sterilized medical device product. ..
【０００４】 包装体ａは、合成紙又は不織布等からなるフィルターｃが長手方向と直交する 断面において断面Ｖ字形に成形され、該Ｖ字の両側面の外側上部に沿ったヒート シール部ｄ，ｅにポリエチレン又はポリプロピレン等の合成樹脂シートｆがヒー トシールによって気密に接着されており、合成樹脂シートｆの長手方向の両端部 ｇ，ｈの一方の端部ｇがヒートシールによって密閉された後に、合成樹脂シート ｆの内部にディスポーザブル・シリンジｂが収納され、合成樹脂シートｆの長手 方向の両端部ｇ，ｈの他方の端部ｈがヒートシールによって密閉されて、ディス ポーザブル・シリンジｂが袋状パッケージｉ内に密封されている。ところで、フ ィルターｃは、多数のフィルター空隙を有しており、該フィルター空隙の大きさ が、滅菌ガスとして使用される酸化エチレンガスや高圧蒸気等の分子の大きさよ り大きく、細菌等の異物の大きさより小さく設定されている。In the package a, a filter c made of synthetic paper or non-woven fabric is formed into a V-shaped cross-section in a cross section orthogonal to the longitudinal direction, and heat-sealing parts d and e along the upper outer sides of both side surfaces of the V-shaped structure. A synthetic resin sheet f such as polyethylene or polypropylene is airtightly adhered by a heat seal, and one end g of both ends g and h in the longitudinal direction of the synthetic resin sheet f is hermetically sealed by heat sealing. The disposable syringe b is housed inside the resin sheet f, and the other end h of both ends g and h in the longitudinal direction of the synthetic resin sheet f is hermetically sealed by heat sealing, so that the disposable syringe b is a bag-shaped package. It is sealed in i. By the way, the filter c has a large number of filter voids, and the size of the filter voids is larger than the size of the molecules such as ethylene oxide gas and high-pressure steam used as sterilizing gas, and foreign substances such as bacteria are present. Is set smaller than the size of.
【０００５】 包装体ａは、図１３に示すように組み立てられた後、圧力容器内に入れられ、 圧力容器内で減圧及び滅菌ガスによる加圧が数回繰り返されるところの滅菌処理 が施されて、フィルターｃのフィルター空隙を通して滅菌ガスが袋状パッケージ ｉ内に導入され、袋状パッケージｉ内が隅々まで滅菌ガスで滅菌される。After the package a is assembled as shown in FIG. 13, the package a is put in a pressure vessel and subjected to a sterilization treatment in which depressurization and pressurization with sterilization gas are repeated several times in the pressure vessel. The sterilizing gas is introduced into the bag-shaped package i through the filter gap of the filter c, and the bag-shaped package i is sterilized by the sterilizing gas in every corner.
【０００６】 ところで、袋状パッケージ内で無菌状態を保持される滅菌済み医療用具の中に は、人工心肺の使い捨て部品等のように、人工心肺等の本体に取り付けられて使 用されるため、袋状パッケージ内から取り出された後に、本体への取り付け作業 が必要な滅菌済み医療用具がある。このような滅菌済み医療用具は、本体への取 り付け作業の作業時間がたとえ短い場合であっても、取り付け作業中に主要部の 内部が大気に晒されるため、該作業中に主要部の内部が大気中の細菌等で汚染さ れる危険性がある。そして、前記医療用具の主要部の内部が細菌等によって汚染 された場合には、汚染を感知することが極めて困難なため、前記汚染された医療 用具が人工心肺等の本体に取り付けられて、患者の治療等に使用される危険性が 極めて高くなってしまうという問題がある。By the way, in a sterilized medical device which is kept sterile in a bag-shaped package, it is used by being attached to the main body of an artificial heart lung, such as a disposable part of an artificial heart lung. There are sterilized medical devices that need to be attached to the main body after being taken out from the bag package. In such a sterilized medical device, even if the work time for the attachment to the main body is short, the inside of the main part is exposed to the atmosphere during the attachment work, so that the main part of the main body is exposed during the work. There is a risk that the inside will be contaminated with bacteria in the atmosphere. When the inside of the main part of the medical device is contaminated by bacteria or the like, it is extremely difficult to detect the contamination, so the contaminated medical device is attached to the main body such as an artificial heart-lung machine, and There is a problem that the risk of being used for the treatment of is extremely high.
【０００７】 上述したディスポーザブル・シリンジや人工心肺の使い捨て部品等の滅菌済み 医療用具では、包装体に袋状パッケージが使用されているが、滅菌済み医療用具 の中には、使い捨て注射針等のように、医師や看護婦等によって診断又は治療等 の目的で常時携帯される滅菌済み医療用具があり、使い捨て注射針等の滅菌済み 医療用具の包装体には、かさばらないこと及び丈夫であることが要求されるため 、以下に説明する容器状パッケージも使用されている。In the sterilized medical devices such as the disposable syringe and the disposable parts of the heart-lung machine described above, a bag-shaped package is used for the packaging body. In addition, there are sterilized medical devices that are always carried by doctors, nurses, etc. for the purpose of diagnosis or treatment, and the packaging of sterilized medical devices such as disposable injection needles should be bulky and durable. As required, the container package described below is also used.
【０００８】 滅菌済み医療用具の従来の包装体の他の一例は、図１５〜図１７に示されてお り、使い捨て注射針ｑの包装体ｒである。Another example of a conventional package of a sterilized medical device is shown in FIGS. 15 to 17, which is a package r of a disposable injection needle q.
【０００９】 包装体ｒは、針管ｏ及び針もとｐからなる使い捨て注射針ｑ並びに中空有底の キャップ部ｓ及び中空有底の収納部ｔからなるプラスチック製の容器状パッケー ジｕで構成されている。容器状パッケージｕは、収納部ｔの収納開口部ｖ寄りの 直円筒状の外周面が収納はめ合い面ｘとされ、キャップ部ｓのキャップ開口部ｗ 寄りの直円筒状の内周面がキャップはめ合い面ｙとされて、収納はめ合い面ｘの 外径Ａとキャップはめ合い面ｙの内径Ｂとがほぼ同一の値に設定されており、収 納部ｔの中空部の内周面ｍが収納開口部ｖに向かって拡径された円錐状のテーパ 面とされている。使い捨て注射針ｑは、針もとｐの針もと開口部ｚ寄りの外周面 ｎが針管ｏに向かって縮径された円錐状のテーパ面とされている。ところで、収 納部ｔは、０．１ｍｍ程度の深さを有する縦溝ｊが収納はめ合い面ｘの長手方向 に１，２本凹設されて、図１６に示されるような縦溝構造とされているか、又は 、０．１ｍｍ程度の高さを有する環状リブαが収納はめ合い面ｘの周方向に１， ２本突設され、各環状リブαに切り欠き部βがそれぞれ１箇所づつ形成されて、 図１７に示されるような環状リブ構造とされている。The package r is composed of a disposable injection needle q consisting of a needle tube o and a needle base p, and a plastic container-like package u consisting of a hollow bottomed cap section s and a hollow bottomed storage section t. ing. In the container-shaped package u, a right cylindrical outer peripheral surface of the storage portion t near the storage opening v is a storage mating surface x, and a right cylindrical inner peripheral surface of the cap portion s near the cap opening w is a cap. As the fitting surface y, the outer diameter A of the storage fitting surface x and the inner diameter B of the cap fitting surface y are set to substantially the same value, and the inner peripheral surface m of the hollow portion of the receiving portion t is set. Is a conical tapered surface whose diameter increases toward the storage opening v. The disposable injection needle q has a conical tapered surface in which the outer peripheral surface n of the needle base p near the opening z is narrowed toward the needle tube o. By the way, in the storage part t, a vertical groove j having a depth of about 0.1 mm is recessed in the longitudinal direction of the storage fitting surface x to form a vertical groove structure as shown in FIG. Or one or two annular ribs α having a height of about 0.1 mm project in the circumferential direction of the housing fitting surface x, and each annular rib α has one notch β. It is formed to have an annular rib structure as shown in FIG.
【００１０】 使い捨て注射針ｑの針もとｐの外周面ｎを容器状パッケージｕの収納部ｔの内 周面ｍで保持し、使い捨て注射針ｑの針管ｏを収納部ｔの中空部に収納して、容 器状パッケージｕの収納部ｔとキャップ部ｓとを互いにはめ合わせると、収納部 ｔが縦溝構造とされている場合には、収納はめ合い面ｘとキャップ部ｓのキャッ プはめ合い面ｙとが互いに気密に嵌合されて、縦溝ｊに沿って微小な断面積を有 する縦溝空隙ｋが形成され、容器状パッケージｕの内部と外部が縦溝空隙ｋによ って連通される。また、収納部ｔが環状リブ構造とされている場合には、環状リ ブαの頂部がキャップはめ合い面ｙによって圧縮されて、環状リブαがキャップ はめ合い面ｙに密接され、収納はめ合い面ｘとキャップはめ合い面ｙとが環状リ ブαによって隔離されて、収納はめ合い面ｘとキャップはめ合い面ｙとの間に微 小空間が形成されると共に、環状リブαの切り欠き部βに切り欠き空隙γが形成 されて、容器状パッケージｕの内部と外部が微小空間及び切り欠き空隙γによっ て連通される。すなわち、包装体ｒは、収納部ｔが縦溝構造とされていても、あ るいは、環状リブ構造とされていても、容器状パッケージｕの内部と外部が連通 される。従って、包装体ｒを組み立てた後に、上述した滅菌処理を包装体ｒに施 すと、包装体ｒは、容器状パッケージｕの内部が滅菌ガスによって滅菌されて、 容器状パッケージｕ内の使い捨て注射針ｑが無菌状態に保持される。The outer peripheral surface n of the needle base p of the disposable injection needle q is held by the inner peripheral surface m of the storage portion t of the container package u, and the needle tube o of the disposable injection needle q is stored in the hollow portion of the storage portion t. Then, when the storage portion t of the container-shaped package u and the cap portion s are fitted to each other, if the storage portion t has a vertical groove structure, the storage fitting surface x and the cap portion s are capped. The mating surfaces y are airtightly fitted to each other to form a vertical groove space k having a minute cross-sectional area along the vertical groove j, and the inside and outside of the container-shaped package u are formed by the vertical groove space k. Is communicated. Further, when the storage portion t has an annular rib structure, the top of the annular rib α is compressed by the cap fitting surface y, and the annular rib α is brought into close contact with the cap fitting surface y, so that the housing fitting is performed. The surface x and the cap fitting surface y are separated by the annular rib α to form a microscopic space between the housing fitting surface x and the cap fitting surface y, and the cutout portion of the annular rib α. A cutout space γ is formed in β, and the inside and outside of the container-shaped package u are communicated with each other by the minute space and the cutout space γ. That is, in the package r, whether the storage portion t has the vertical groove structure or the annular rib structure, the inside and the outside of the container-shaped package u are communicated with each other. Therefore, when the package r is subjected to the above-described sterilization treatment after the package r is assembled, the package r is sterilized by the sterilizing gas inside the package r, and the disposable injection in the package u is performed. The needle q is kept sterile.
【００１１】 ところで、容器状パッケージｕの収納部ｔとキャップ部ｓは、それぞれ射出成 形されるのであるが、射出成形される際に僅かに収縮するため、収納部ｔには、 収納はめ合い面ｘの外径Ａに微妙なばらつきが生じ、キャップ部ｓには、キャッ プはめ合い面ｙの内径Ｂに微妙なばらつきが生じる。By the way, the storage part t and the cap part s of the container-shaped package u are respectively injection-molded. However, since they slightly shrink when injection-molded, the storage part t is fitted with a storage fitting. A slight variation occurs in the outer diameter A of the surface x, and a slight variation in the inner diameter B of the cap fitting surface y in the cap portion s.
【００１２】 収納部ｔが縦溝構造とされている場合には、縦溝ｊが収納はめ合い面ｘに凹設 されているため、キャップはめ合い面ｙの内径Ｂが収納はめ合い面ｘの外径Ａよ り少しでも大きくなると、収納部ｔとキャップ部ｓとのはめ合いが甘くなってし まう。そして、前記はめ合いが甘くなった場合には、上述した滅菌処理が包装体 ｒに施されて、容器状パッケージｕ内が一旦は無菌状態にされても、滅菌処理後 に大気中の細菌等の異物が容器状パッケージｕ内に侵入して、容器状パッケージ ｕ内の使い捨て注射針ｑが前記異物によって再汚染される危険性が高くなる。従 って、収納部ｔが縦溝構造とされている場合には、収納部ｔとキャップ部ｓとの はめ合いが甘くならないように、収納部ｔとキャップ部ｓとを適切にはめ合わせ る必要があり、適切なはめ合いを実現させるため、複数の収納部ｔ及びキャップ 部ｓから適切なはめ合いとなる組合せを選び出す必要がある。すなわち、縦溝構 造には、収納部ｔとキャップ部ｓとの適切なはめ合いを実現させるために手間が 係るという問題がある。When the storage portion t has a vertical groove structure, since the vertical groove j is recessed in the storage fitting surface x, the inner diameter B of the cap fitting surface y is equal to the storage fitting surface x. If the outer diameter A is slightly larger than that of the outer diameter A, the fitting between the storage portion t and the cap portion s will be weakened. When the fit becomes loose, the above-mentioned sterilization treatment is applied to the package r, and even if the inside of the container-shaped package u is once made aseptic, the bacteria in the atmosphere after the sterilization treatment are removed. There is a high risk that the foreign matter will enter the container-shaped package u and the disposable injection needle q in the container-shaped package u will be re-contaminated by the foreign matter. Therefore, when the storage part t has a vertical groove structure, the storage part t and the cap part s are properly fitted together so that the fitting of the storage part t and the cap part s is not loosened. It is necessary to select an appropriate fitting combination from the plurality of storage parts t and the cap part s in order to realize an appropriate fitting. That is, the vertical groove structure has a problem that it takes time to achieve proper fitting between the storage portion t and the cap portion s.
【００１３】 これに対し、収納部ｔが環状リブ構造とされている場合には、環状リブαが収 納はめ合い面ｘに突設されており、キャップはめ合い面ｙの内径Ｂ及び収納はめ 合い面ｘの外径Ａの製造時のばらつきが環状リブαの圧縮によって吸収されるた め、収納部ｔとキャップ部ｓとの適切なはめ合いを実現させるための手間が係ら ない。しかし、収納部ｔが環状リブ構造とされている場合には、環状リブαの切 り欠き部βに形成される切り欠き空隙γの長さが短いため、滅菌処理後に大気中 の細菌等の異物が切り欠き空隙γを通って容器状パッケージｕ内に侵入して、容 器状パッケージｕ内の使い捨て注射針ｑが前記異物によって再汚染される危険性 がある。すなわち、環状リブ構造には、フィルター機能不良による再汚染の危険 性があるという問題がある。On the other hand, when the storage portion t has an annular rib structure, the annular rib α is provided so as to project from the storage fitting surface x, and the inner diameter B of the cap fitting surface y and the storage fitting surface y. Since the variation in the outer diameter A of the mating surface x during manufacture is absorbed by the compression of the annular rib α, it does not take time and effort to realize the proper fitting between the housing portion t and the cap portion s. However, when the storage part t has an annular rib structure, the length of the notch gap γ formed in the notch β of the annular rib α is short, so that bacteria such as bacteria in the atmosphere after sterilization treatment are not present. There is a risk that foreign matter may enter the container-shaped package u through the cutout space γ and re-contaminate the disposable injection needle q in the container-shaped package u with the foreign matter. That is, the annular rib structure has a problem that there is a risk of recontamination due to a defective filter function.
【００１４】 ところで、適切なはめ合いを実現させるための手間が係る又はフィルター機能 不良による再汚染の危険性があるという問題は、使い捨て注射針ｑの容器状パッ ケージｕに限定される問題ではなく、容器状パッケージが使用されている、滅菌 済み医療用具の包装体に共通の問題である。すなわち、滅菌済み医療用具の中に は形状が大きい物や重量が重い物があり、これらは、その大きさや重さ故に袋状 パッケージを破損して、該袋状パッケージ内の無菌状態を台無しにする危険性が あるため、形状が大きい滅菌済み医療用具や重量が重い滅菌済み医療用具の包装 体には、袋状パッケージではなく容器状パッケージが使用されているのであるが 、該容器状パッケージにも共通する問題である。By the way, the problem that it takes time and labor for realizing an appropriate fitting or there is a risk of recontamination due to defective filter function is not limited to the container-shaped package u of the disposable injection needle q. This is a common problem with sterilized medical device packaging, where container packages are used. That is, some sterilized medical devices have large shapes and heavy weights, and these damage the bag-shaped package due to its size and weight, ruining the aseptic state in the bag-shaped package. Therefore, a container-shaped package is used instead of a bag-shaped package for packaging of sterilized medical devices with large shapes and heavy sterilized medical devices. Is a common problem.
【００１５】[0015]
従来技術の前記問題点に鑑み、本考案は、以下の課題を解決することを目的と している。 In view of the above problems of the prior art, the present invention aims to solve the following problems.
【００１６】 人工心肺の使い捨て部品等のように、無菌状態の袋状パッケージ内から取り出 した後に人工心肺等の本体への取り付け作業を行なう必要がある滅菌済み医療用 具において、該医療用具を袋状パッケージ内から取り出しても、該医療用具の主 要部が有するところの、本体に取り付けられる全開口部のそれぞれの開口部の内 部を、それぞれの開口部が本体に取り付けられる直前まで、無菌状態で保持でき るようにして、前記主要部の内部が前記取り付け作業中に細菌等によって汚染さ れる危険性を減少させる。A sterilized medical device, such as a disposable component of a heart-lung machine, which needs to be attached to the body of the heart-lung machine after being taken out from the bag in a sterile state. Even when taken out from the bag-shaped package, the inside of each opening of all the openings attached to the main body, which the main part of the medical device has, until just before each opening is attached to the main body, The possibility of being maintained in an aseptic state reduces the risk that the inside of the main part will be contaminated by bacteria or the like during the mounting operation.
【００１７】 使い捨て注射針等の滅菌済み医療用具を無菌状態で保持するための容器状パッ ケージにおいて、縦溝構造の場合にかかる手間（適切なはめ合い実現させるめの 手間）を削減すると共に、環状リブ構造が有する危険性（フィルター機能不良に よる再汚染の危険性）をなくする。[0017] In a container-shaped package for holding a sterile medical device such as a disposable injection needle in an aseptic state, it is possible to reduce the time and labor required for the vertical groove structure (the time and effort for realizing an appropriate fitting), and Eliminates the risk of the annular rib structure (risk of recontamination due to filter malfunction).
【００１８】[0018]
本考案は、前記課題を解決するため、互いにはめ合わされる２部材の何れか一 方の部材のはめ合い面にネジ部が形成され、該ネジ部のネジのピッチとネジ山の 高さが共に著しく小さく設定されており、前記２部材が互いにはめ合わされ、前 記ネジ部を有しない部材のはめ合い面で前記ネジ山が圧縮されて、前記ネジ部を 有しない部材のはめ合い面に前記ネジ山が密接されていると共に、前記ネジ部の ネジの谷と前記ネジ部を有しない部材のはめ合い面との間に微小空隙が形成され ているという構成とされている。 According to the present invention, in order to solve the above-mentioned problems, a screw portion is formed on a fitting surface of one of two members to be fitted to each other, and the screw pitch and the height of the screw thread of the screw portion are the same. It is set to be extremely small, and the two members are fitted to each other, and the thread is compressed at the fitting surface of the member having no threaded portion, and the screw is fitted to the fitting surface of the member having no threaded portion. The crests are in close contact with each other, and a minute gap is formed between the thread trough of the threaded portion and the fitting surface of the member having no threaded portion.
【００１９】[0019]
本考案に係る包装用封止部は、前記構成とされているので、微小空隙がネジ部 のネジの谷に沿って螺旋状に連続して形成される。このため、包装用封止部の内 部と外部が螺旋状に連続して形成される微小空隙によって連通される。しかも、 本考案に係る包装用封止部に形成される微小空隙は、螺旋状に連続して形成され るため、従来技術の項で説明したフィルター空隙及び従来技術の項で説明した切 り欠き空隙と比べて空隙の長さが著しく長くなる。従って、本考案に係る包装用 封止部は、微小空隙の断面積が前記フィルター空隙及び前記切り欠き空隙と比べ て多少大きくなっても、包装用封止部の内部と外部との間に大きな圧力差を人為 的に生じさせない限り、包装用封止部の内部と外部の気体の流通が阻止されて、 包装用封止部の外部から内部への細菌等の異物の進入が阻止される。すなわち、 本考案に係る包装用封止部を滅菌済み医療用具の包装体に採用した場合には、従 来技術の項で説明した滅菌処理を該包装体に施して包装用封止部の内部と外部と の間に大きな圧力差を生じさせることにより、該包装体の内部を無菌状態にする ことが可能になると共に、該包装体の内部の無菌状態を包装用封止部の開封時ま で保持することが可能になる。 Since the packaging sealing portion according to the present invention is configured as described above, the minute voids are continuously formed in a spiral shape along the valleys of the threads of the threaded portion. Therefore, the inner part and the outer part of the packaging sealing part are communicated with each other by the minute voids formed continuously in a spiral shape. Moreover, since the microscopic voids formed in the packaging sealing portion according to the present invention are continuously formed in a spiral shape, the filter voids described in the section of the prior art and the cutouts described in the section of the prior art. The length of the void is significantly longer than that of the void. Therefore, the packaging sealing part according to the present invention has a large gap between the inside and the outside of the packaging sealing part even if the cross-sectional area of the micro voids is slightly larger than that of the filter void and the cutout void. As long as the pressure difference is not artificially generated, the flow of gas inside and outside the packaging sealing portion is blocked, and foreign substances such as bacteria are prevented from entering the packaging sealing portion from the outside. That is, when the packaging sealing part according to the present invention is adopted in the packaging body of sterilized medical devices, the packaging body is subjected to the sterilization treatment described in the section of the prior art, and the inside of the packaging sealing part is sealed. By creating a large pressure difference between the inside and the outside of the package, the inside of the package can be made sterile, and the inside of the package can be kept sterile until the packaging sealing portion is opened. Can be held at.
【００２０】 また、本考案に係る包装用封止部は、前記構成とされているので、互いにはめ 合わされる２部材のはめ合いで多少のばらつきが生じても、２部材を互いにはめ 合わせるときのネジ山の圧縮によって前記ばらつきが吸収される。Further, since the packaging sealing portion according to the present invention is configured as described above, even if there is some variation in the fitting of the two members fitted to each other, when the two members are fitted to each other, The variation is absorbed by the compression of the threads.
【００２１】[0021]
本考案に係る包装用封止部の実施例を図１〜図１２に基づいて以下に説明する 。 An embodiment of the packaging sealing portion according to the present invention will be described below with reference to FIGS.
【００２２】 第１の実施例は、図１に示されており、人工心肺の使い捨て部品等の滅菌済み 医療用具２の開口孔３に本考案に係る包装用封止部が採用されている前記滅菌済 み医療用具２の包装体の要部１を示している。互いにはめ合わされる２部材のう ちの一方の部材である前記滅菌済み医療用具２は、開口孔３の開口部４寄りの直 円筒状のネジ面が孔はめ合い面５とされて、孔はめ合い面５にネジ部６が形成さ れており、ネジ部６のネジのピッチＰが１ｍｍに設定され、ネジ部６の断面波型 形状のネジ山７の高さＨが０．１ｍｍに設定されて、ネジ部６のネジのピッチＰ 及びネジ山７の高さＨが共に著しく小さく設定されている。互いにはめ合わされ る２部材のうちの他方の部材であるプラスチック製の封止栓８は、端面９に向か って縮径された円錐状のテーパ面が栓はめ合い面１０とされており、栓はめ合い 面１０の傾きが１００分の１程度に設定されている。また、端面９の外周縁が全 周に亘って面取りされており、栓はめ合い面１０の最小外径Ｃが開口孔３の内径 Ｄとほぼ同一の値に設定されている。The first embodiment is shown in FIG. 1, in which the packaging sealing portion according to the present invention is adopted in the opening hole 3 of the sterilized medical device 2 such as a disposable part of a heart-lung machine. The main part 1 of the package of the sterilized medical device 2 is shown. In the sterilized medical device 2 which is one of the two members to be fitted with each other, the straight cylindrical screw surface near the opening 4 of the opening hole 3 is used as the hole fitting surface 5, and the hole fitting surface 5 is fitted. A thread 6 is formed on the surface 5, the thread pitch P of the thread 6 is set to 1 mm, and the height H of the thread 7 having the corrugated cross section of the thread 6 is set to 0.1 mm. Thus, both the pitch P 1 of the threads of the threaded portion 6 and the height H of the thread 7 are set to be extremely small. The plastic sealing plug 8 which is the other member of the two members fitted to each other has a conical taper surface whose diameter is reduced toward the end surface 9 as the plug fitting surface 10. The inclination of the plug fitting surface 10 is set to about 1/100. Further, the outer peripheral edge of the end surface 9 is chamfered over the entire circumference, and the minimum outer diameter C of the plug fitting surface 10 is set to be substantially the same as the inner diameter D of the opening hole 3.
【００２３】 封止栓８を端面９側から開口孔３の開口部４へ挿入して押進させると、孔はめ 合い面５に形成されているネジ部６のネジ山７が、開口部４寄りのネジ山７から 順に、栓はめ合い面１０に当接され、栓はめ合い面１０で圧縮されて、栓はめ合 い面１０に密接されていく。また、ネジ部６のネジの谷１１と栓はめ合い面１０ との間に微小空隙１２が形成されると共に、微小空隙１２が開口部４寄りのネジ の谷１１から連続して螺旋状に形成されていく。最も開口部４寄りに形成される 微小空隙１２が栓はめ合い面１０で閉塞される前に封止栓８の押進を停止させて 、栓はめ合い面１０と孔はめ合い面５とのはめ合いを完了させると、ネジ部６の ネジの谷１１に沿って螺旋状に連続して形成される微小空隙１２によって開口孔 ３の内部と外部が連通されるため、開口孔３が封止栓８によって密閉されること なく、栓はめ合い面１０と孔はめ合い面５が互いにはめ合わされる。When the sealing plug 8 is inserted into the opening 4 of the opening hole 3 from the end surface 9 side and pushed forward, the screw thread 7 of the screw portion 6 formed on the hole fitting surface 5 becomes From the screw thread 7 nearer to the plug fitting surface 10, the plug fitting surface 10 is abutted, compressed by the plug fitting surface 10 and brought into close contact with the plug fitting surface 10. In addition, a minute void 12 is formed between the screw trough 11 of the screw portion 6 and the plug fitting surface 10, and the minute void 12 is continuously formed in a spiral shape from the screw trough 11 near the opening 4. Will be done. Before the micro voids 12 formed closest to the opening 4 are closed by the plug fitting surface 10, the pushing of the sealing plug 8 is stopped so that the plug fitting surface 10 and the hole fitting surface 5 fit together. When the fitting is completed, the inside and outside of the opening hole 3 are communicated with each other by the minute voids 12 which are continuously formed in a spiral shape along the thread trough 11 of the screw portion 6, so that the opening hole 3 is sealed. The plug fitting surface 10 and the hole fitting surface 5 are fitted to each other without being sealed by 8.
【００２４】 ところで、第１の実施例は、封止栓８の端面９の外周縁が全周に亘って面取り されていると共に、栓はめ合い面１０が端面９に向かって縮径された円錐状のテ ーパ面とされているので、栓はめ合い面１０と孔はめ合い面５とのはめ合いがス ムーズに行なわれる。By the way, in the first embodiment, the outer peripheral edge of the end surface 9 of the sealing plug 8 is chamfered over the entire circumference, and the plug fitting surface 10 is a cone whose diameter is reduced toward the end surface 9. Since the tapered taper surface is formed, the plug fitting surface 10 and the hole fitting surface 5 are fitted smoothly.
【００２５】 第１の実施例は、上述したように、螺旋状に連続して形成される微小空隙１２ によって開口孔３の内部と外部が連通される。このため、開口孔３に本考案に係 る包装用封止部が採用されている人工心肺の使い捨て部品等の滅菌済み医療用具 ２を圧力容器内に密閉した後、圧力容器内を真空状態に減圧して、開口孔３の内 部と外部に大きな圧力差を生じさせると、螺旋状に連続して形成されている微小 空隙１２を通って開口孔３の内部の空気が開口孔３の外部に抜け出て、開口孔３ の内部が真空状態になる。この後、酸化エチレンガスや高圧蒸気等の滅菌ガスで 圧力容器内を加圧し、開口孔３の内部と外部に再び大きな圧力差を生じさせと、 螺旋状に連続して形成されている微小空隙１２を通って滅菌ガスが開口孔３の内 部に入り込み、開口孔３の内部が滅菌ガスで滅菌される。従って、圧力容器内で 上述した減圧及び加圧を数回繰り返す滅菌処理を施すことによって、第１の実施 例は、開口孔３の内部が完全に無菌状態となる。In the first embodiment, as described above, the inside and outside of the opening hole 3 are communicated with each other by the minute voids 12 formed continuously in a spiral shape. Therefore, after the sterilized medical device 2 such as the disposable part of the heart-lung machine in which the packaging sealing portion according to the present invention is adopted in the opening hole 3 is sealed in the pressure container, the pressure container is evacuated. When the pressure is reduced to generate a large pressure difference between the inside and the outside of the opening hole 3, the air inside the opening hole 3 passes through the minute voids 12 formed continuously in a spiral shape and the outside of the opening hole 3 is discharged. Then, the inside of the opening hole 3 becomes a vacuum state. After that, sterilizing gas such as ethylene oxide gas or high-pressure steam pressurizes the inside of the pressure vessel to again generate a large pressure difference between the inside and the outside of the opening hole 3, and the minute voids formed continuously in a spiral shape are formed. The sterilizing gas enters the inside of the opening 3 through 12 and the inside of the opening 3 is sterilized with the sterilizing gas. Therefore, by performing the sterilization process in which the above-described depressurization and pressurization are repeated several times in the pressure vessel, the inside of the opening hole 3 becomes completely sterile in the first embodiment.
【００２６】 また、第１の実施例は、上述したように、微小空隙１２が螺旋状に連続して形 成されるので、従来例の項で説明した図１３に示されるフィルターｃのフィルタ ー空隙と比べて微小空隙１２の長さが著しく長くなる。このため、微小空隙１２ の断面積が前記フィルター空隙の断面積と比べて多少大きくなっても、開口孔３ の内部と外部の空気の流通が微小空隙１２によって阻止されるので、開口孔３の 外部から内部への細菌等の異物の進入が阻止される。従って、上記滅菌処理が施 されると、封止栓８が取り外されるまで、開口孔３の内部が無菌状態で保持され る。In addition, in the first embodiment, as described above, since the minute voids 12 are continuously formed in a spiral shape, the filter of the filter c shown in FIG. 13 described in the section of the conventional example. The length of the minute voids 12 becomes significantly longer than the voids. Therefore, even if the cross-sectional area of the microscopic void 12 is slightly larger than the cross-sectional area of the filter void, the flow of air inside and outside the opening 3 is blocked by the microscopic void 12, so that Invasion of foreign substances such as bacteria from the outside to the inside is prevented. Therefore, when the above sterilization process is performed, the inside of the opening hole 3 is kept aseptic until the sealing plug 8 is removed.
【００２７】 更に、第１の実施例は、図１３に示されるような袋状パッケージとの併用が可 能である。このため、人工心肺の使い捨て部品等のように、無菌状態の袋状パッ ケージ内から取り出した後に人工心肺等の本体への取り付け作業を行なう必要が ある滅菌済み医療用具３において、該医療用具３の主要部が有するところの、人 工心肺等の本体に取り付けられる全ての開口部に本考案に係る包装用封止部を採 用すると共に、袋状パッケージ内に滅菌済み医療用具３を収納して包装体を形成 した場合には、該包装体に上述した滅菌処理を施せば、袋状パッケージの内部だ けでなく、滅菌済み医療用具３の主要部の内部も無菌状態となる。しかも、この 場合には、滅菌済み医療用具３を人工心肺等の本体に取り付ける際に、滅菌済み 医療用具３を袋状パッケージから取り出しても、滅菌済み医療用具３の主要部が 有するところの、人工心肺等の本体に取り付けられる全ての開口部を構成する各 開口部において、各開口部を人工心肺等の本体に取り付ける直前まで、各開口部 に挿入されている封止栓を取り外さなければ、滅菌済み医療用具３は、人工心肺 等の本体への取り付け作業中に、主要部の内部が殆ど大気中に晒されない。従っ て、本考案に係る包装用封止部と袋状パッケージを併用して滅菌済み医療用具３ の包装体を形成した場合には、単に袋状パッケージだけを使用している従来の包 装体と比べて、滅菌済み医療用具３の人工心肺等の本体への取り付け作業中に、 滅菌済み医療用具３の主要部の内部が細菌等によって汚染される危険性が減少す る。Furthermore, the first embodiment can be used together with a bag-shaped package as shown in FIG. For this reason, in a sterilized medical device 3 such as a disposable component of a heart-lung machine, which needs to be attached to the body of the heart-lung machine after being taken out from the bag-shaped package in a sterile state, the medical device 3 The packaging sealing part according to the present invention is applied to all the openings that are attached to the main body of the artificial heart-lung machine, etc., which is included in the main part of When the package is formed by performing the above-mentioned sterilization treatment on the package, not only the inside of the bag-shaped package but also the inside of the main part of the sterilized medical device 3 becomes aseptic. Moreover, in this case, even when the sterilized medical device 3 is taken out from the bag-shaped package when the sterilized medical device 3 is attached to the main body such as the heart-lung machine, the main part of the sterilized medical device 3 has At each opening that constitutes all the openings attached to the body of the heart-lung machine, etc., the sealing plugs inserted in the respective openings must be removed until immediately before the openings are attached to the body of the heart-lung machine, etc. The interior of the main part of the sterilized medical device 3 is hardly exposed to the atmosphere during the work of attaching it to the body of the heart-lung machine or the like. Therefore, when a packaging body of the sterilized medical device 3 is formed by using the packaging sealing portion according to the present invention and the bag-shaped package together, the conventional packaging body that uses only the bag-shaped package is used. Compared with the above, the risk of contamination of the inside of the main part of the sterilized medical device 3 with bacteria or the like during the attachment work of the sterilized medical device 3 to the body of the heart-lung machine or the like is reduced.
【００２８】 ところで、封止栓８の材質は上述した材質に限定されないし、ネジ部６のネジ 山７の高さＨ及びネジのピッチＰ並びに栓はめ合い面１０の傾きは上述した数値 に限定されない。また、第１の実施例では、図１に示されるように、孔はめ合い 面５が直円筒状のネジ面とされて、孔はめ合い面５にネジ部６が形成されており 、栓はめ合い面１０が端面９に向かって縮径された円錐状のテーパ面とされてい るが、栓はめ合い面１０及び孔はめ合い面５の形状は第１の実施例に限定されな いし、ネジ部６が形成されるのは孔はめ合い面５に限定されない。以下に、第２ 〜第６の実施例として、第１の実施例と異なる構造を図２〜図６に基づいて説明 する。By the way, the material of the sealing plug 8 is not limited to the above-mentioned material, and the height H of the screw thread 7 of the screw portion 6, the pitch P of the screw, and the inclination of the plug fitting surface 10 are limited to the above-mentioned numerical values.

A threaded portion 6b is formed on the inner surface of the plug, and the plug fitting surface 10b is a cylindrical outer peripheral surface.

【００３２】 第５の実施例は、図５に示されており、孔はめ合い面５ｄが開口部４ｄに向か って拡径された円錐状のテーパネジ面とされて、孔はめ合い面５ｄにネジ部６ｄ が形成されており、栓はめ合い面１０ｄが端面９ｄに向かって縮径された円錐状 のテーパ面とされている。また、孔はめ合い面５ｄ及び栓はめ合い面１０ｄのそ れぞれの傾きがほぼ同一とされている。A fifth embodiment is shown in FIG. 5, in which the hole fitting surface 5d is a conical taper screw surface whose diameter is expanded toward the opening 4d, and the hole fitting surface 5d is formed. A threaded portion 6d is formed on the inner surface of the plug, and the plug fitting surface 10d is a conical tapered surface whose diameter is reduced toward the end surface 9d. The inclinations of the hole fitting surface 5d and the plug fitting surface 10d are substantially the same.
【００３３】 第６の実施例は、図６に示されており、孔はめ合い面５ｅが開口部４ｅに向か って拡径された円錐状のテーパ面とされており、栓はめ合い面１０ｅが端面９ｅ に向かって縮径された円錐状のテーパネジ面とされて、栓はめ合い面１０ｅにネ ジ部６ｅが形成されている。また、孔はめ合い面５ｅ及び栓はめ合い面１０ｅの それぞれの傾きが同一とされている。The sixth embodiment is shown in FIG. 6, in which the hole fitting surface 5e is a conical taper surface whose diameter is enlarged toward the opening 4e, and the plug fitting surface 5e is formed. 10e is a conical taper screw surface whose diameter is reduced toward the end surface 9e, and a screw portion 6e is formed on the plug fitting surface 10e.

【００３４】 ところで、図示されてはいないが、孔はめ合い面が直円筒状のネジ面とされて 、孔はめ合い面にネジ部が形成されており、栓はめ合い面が円柱状の外周面とさ れていてもよいし、孔はめ合い面が直円筒状の内周面とされており、栓はめ合い 面にネジ部が形成されて、栓はめ合い面が円柱状のネジ面とされていてもよい。 ただし、上述した実施例のように、孔はめ合い面及び栓はめ合い面の何れか一方 又は両方が円錐状とされていた方が、両方ともテーパを有しない面とされている 場合と比べて、栓はめ合い面と孔はめ合い面のはめ合いがよりスムーズに行なわ れるため、より好ましい。By the way, although not shown, the hole fitting surface is a right cylindrical threaded surface, and a threaded portion is formed on the hole fitting surface, and the plug fitting surface is a cylindrical outer peripheral surface.

However, as in the above-described embodiment, when one or both of the hole fitting surface and the plug fitting surface are conical, both are not tapered, compared with the case where both surfaces are not tapered. It is more preferable that the plug fitting surface and the hole fitting surface are fitted more smoothly.
【００３５】 上述した第１〜第６の実施例では、滅菌済み医療用具として、人工心肺等の本 体への取り付け作業が必要であるところの、人工心肺の使い捨て部品等の滅菌済 み医療用具が取り上げられているが、次に、滅菌済み医療用具として使い捨て注 射針を取り上げ、該注射針を無菌状態で保持するための容器状パッケージに本考 案に係る包装用封止部を採用した場合の実施例を図７〜図９に基づいて以下に説 明する。In the above-described first to sixth embodiments, as sterilized medical devices, sterilized medical devices such as disposable parts of the heart-lung machine, which need to be attached to the body of the heart-lung machine or the like. Next, the disposable injection needle was picked up as a sterilized medical device, and the packaging sealing part according to the present invention was adopted as a container-shaped package for holding the injection needle in a sterile state. An example of the case will be described below with reference to FIGS.
【００３６】 第７の実施例は、図７，図８に示されており、使い捨て注射針２１とプラスチ ック製の容器状パッケージ２２から構成されている包装体２０である。包装体２ ０は、既に従来技術の項で図１５〜図１７に基づいて説明した包装体ｒの構造と ほぼ同じ構造とされているが、容器状パッケージ２２の構造が、図１５及び図１ ６に示される容器状パッケージｕの構造と比べると次の点で異なっている。互い にはめ合わされる２部材の一方の部材であるキャップ部２３は、キャップはめ合 い面２４がキャップ開口部２７寄りの直円筒状のネジ面とされて、キャップはめ 合い面２４に断面波型形状のネジ部２５が形成されており、ネジ部２５のネジの ピッチＰ１が１ｍｍに設定され、ネジ部２５のネジ山２６の高さが０．１ｍｍに 設定されて、ネジ部２５のネジのピッチＰ１及びネジ山２６の高さが共に著しく 小さく設定されている。また、キャップ開口部２７側の端面２８には、複数の切 込み部２９が形成されている。更に、互いにはめ合わされる２部材の他方の部材 である収納部３０は、収納はめ合い面３１が収納開口部３２に向かって縮径さた 円錐状のテーパ面とされており、収納はめ合い面３１の傾きが１００分の１程度 に設定されており、収納はめ合い面３１の最大外径Ｇがキャップはめ合い面２４ のネジ部２５のネジの谷３３の径Ｉより僅かに小さく設定されている。The seventh embodiment is shown in FIGS. 7 and 8 and is a package 20 including a disposable injection needle 21 and a plastic container-like package 22. The packaging body 20 has almost the same structure as the packaging body r which has already been described based on FIGS. 15 to 17 in the section of the prior art, but the structure of the container-shaped package 22 is shown in FIGS. Compared with the structure of the container-shaped package u shown in FIG. 6, it differs in the following points. The cap portion 23, which is one of the two members to be fitted to each other, has a cap fitting surface 24 as a right cylindrical screw surface near the cap opening 27, and the cap fitting surface 24 has a wavy cross section. The shaped screw portion 25 is formed, the screw pitch P1 of the screw portion 25 is set to 1 mm, and the height of the screw thread 26 of the screw portion 25 is set to 0.1 mm. Both the pitch P1 and the height of the screw thread 26 are set to be extremely small. Further, a plurality of cutouts 29 are formed on the end surface 28 on the side of the cap opening 27. Further, in the storage portion 30 which is the other member of the two members fitted together, the storage fitting surface 31 is a conical taper surface whose diameter is reduced toward the storage opening 32. The inclination of 31 is set to about 1/100, and the maximum outer diameter G of the storage fitting surface 31 is set to be slightly smaller than the diameter I of the screw valley 33 of the screw portion 25 of the cap fitting surface 24. There is.
【００３７】 収納部３０を収納開口部３２側からキャップ部２３のキャップ開口部２７へ挿 入して押進させ、キャップはめ合い面２４と収納はめ合い面３１を互いにはめ合 わせると、第１の実施例で説明したように、収納はめ合い面３１でキャップはめ 合い面２４のネジ部２５のネジ山２６が圧縮され、収納はめ合い面３１にキャッ プはめ合い面２４のネジ部２５のネジ山２６が密接されて、ネジ部２５のネジの 谷３３と収納はめ合い面３１との間に微小空隙３４が形成される。また、微小空 隙３４がネジ部２５のネジの谷３３に沿って螺旋状に連続して形成されると共に 、図８に示されるように、キャップ開口部２７側の端面２８に形成されている切 込み部２９に微小空隙３４が連通される。このため、キャップはめ合い面２４と 収納はめ合い面３１が互いにはめ合わされても、容器状パッケージ２２は、螺旋 状に連続して形成される微小空隙３４によって内部が外部と連通されて、内部が 密閉されない。従って、包装体２０は、使い捨て注射針２１が容器状パッケージ ２２内に納められた後に、第１の実施例で既に説明した滅菌処理が施されること によって、容器状パッケージ２２内の使い捨て注射針２１が滅菌ガスで滅菌され ると共に、キャップが取り外されるまで、容器状パッケージ２２内の使い捨て注 射針２１が無菌状態で保持される。When the storage portion 30 is inserted from the storage opening portion 32 side into the cap opening portion 27 of the cap portion 23 and pushed forward, and the cap fitting surface 24 and the storage fitting surface 31 are fitted to each other, As described in the first embodiment, the thread 26 of the screw portion 25 of the cap fitting surface 24 is compressed at the storage fitting surface 31, and the storage fitting surface 31 is compressed by the screw thread 25 of the cap fitting surface 24. The screw threads 26 are brought into close contact with each other, and a minute gap 34 is formed between the thread trough 33 of the screw portion 25 and the housing fitting surface 31. In addition, a minute space 34 is formed continuously in a spiral shape along the thread valley 33 of the screw portion 25, and is formed on the end surface 28 on the cap opening 27 side as shown in FIG. The minute gap 34 is communicated with the cutout portion 29. Therefore, even if the cap fitting surface 24 and the housing fitting surface 31 are fitted to each other, the inside of the container-shaped package 22 is communicated with the outside by the minute voids 34 formed continuously in a spiral shape, and the inside is Not sealed. Therefore, the packaging body 20 is configured such that after the disposable injection needle 21 is housed in the container-shaped package 22, the sterilization process described in the first embodiment is performed, so that the disposable injection needle in the container-shaped package 22 is packaged. 21 is sterilized with sterilizing gas, and the disposable injection needle 21 in the container package 22 is kept aseptic until the cap is removed.
【００３８】 ところで、容器状パッケージ２２の収納部３０及びキャップ部２３を製造する 際に、収納はめ合い面３１の最大外径Ｇ及びキャップ部２３のキャップはめ合い 面２４のネジ部２５のネジの谷３３の径Ｉに微妙なばらつきが生じても、収納部 ３０とキャップ部２３を互いにはめ合わせると、ネジ部２５のネジ山２６が収納 部３０の収納はめ合い面３１で圧縮されて、前記ばらつきが吸収される。従って 、図７，図８に示される第７の実施例は、従来技術の項で図１６に基づいて説明 した縦溝構造においてかかる手間（適切なはめ合いを実現させるための手間）が 削減される。By the way, when manufacturing the storage portion 30 and the cap portion 23 of the container-shaped package 22, the maximum outer diameter G of the storage fitting surface 31 and the screw of the screw portion 25 of the cap fitting surface 24 of the cap portion 23 are adjusted. Even if there is a slight variation in the diameter I of the valley 33, when the storage portion 30 and the cap portion 23 are fitted to each other, the screw thread 26 of the screw portion 25 is compressed by the storage fitting surface 31 of the storage portion 30, and Variations are absorbed. Therefore, in the seventh embodiment shown in FIGS. 7 and 8, the labor (labor for realizing an appropriate fitting) in the vertical groove structure described in the section of the prior art based on FIG. 16 is reduced. It
【００３９】 また、第７の実施例は、微小空隙３４がネジ部２５のネジの谷３３に沿って螺 旋状に連続して形成されるので、従来技術の項で図１７に基づいて説明した環状 リブ構造が有する切り欠き空隙γの長さと比べて微小空隙３４の長さが著しく長 くなる。従って、第７の実施例は、前記環状リブ構造が有する危険性（フィルタ ー機能不良による再汚染の危険性）がない。Further, in the seventh embodiment, since the minute voids 34 are continuously formed in a spiral shape along the screw valleys 33 of the screw portion 25, the description of the prior art section will be given based on FIG. The length of the minute void 34 is significantly longer than the length of the notch void γ of the annular rib structure. Therefore, in the seventh embodiment, there is no risk of the annular rib structure (risk of recontamination due to defective filter function).
【００４０】 ところで、容器状パッケージ２２の材質は上述した材質に限定されないし、ネ ジ部２５のネジ山２６の高さＨ１及びネジのピッチＰ１は上述した数値に限定さ れず、収納はめ合い面３１の傾きも上述した数値に限定されない。また、第７の 実施例では、図８に示されるように、キャップはめ合い面２４が直円筒状のネジ 面とされて、キャップはめ合い面２４にネジ部２５が形成されており、収納はめ 合い面３１が収納開口部３２に向かって縮径された円錐状のテーパ面とされてい るが、キャップはめ合い面２４及び収納はめ合い面３１の形状は第７の実施例に 限定されないし、ネジ部２５が形成されるのはキャップはめ合い面２４に限定さ れない。By the way, the material of the container-shaped package 22 is not limited to the above-mentioned material, and the height H1 of the screw thread 26 of the screw portion 25 and the pitch P1 of the screw are not limited to the above-mentioned numerical values, and the fitting surface of the housing The inclination of 31 is not limited to the above numerical value. In addition, in the seventh embodiment, as shown in FIG. 8, the cap fitting surface 24 is a right cylindrical threaded surface, and the cap fitting surface 24 is formed with a threaded portion 25. Although the mating surface 31 is a conical taper surface whose diameter is reduced toward the housing opening 32, the shapes of the cap mating surface 24 and the housing mating surface 31 are not limited to those in the seventh embodiment. The threaded portion 25 is not limited to being formed on the mating surface 24 of the cap.
【００４１】 第８の実施例は、図８に示すものと同一部位の拡大断面図である図９に示され ており、図７及び図８に示される第７の実施例とほぼ同一の構造とされて、第７ の実施例と同一の機能を有しているが、第７の実施例と比べて以下の構造が異な っている。キャップはめ合い面２４ａが直円筒状の内周面とされており、収納は め合い面３１ａが収納開口部に向かって縮径された円錐状のテーパネジ面とされ て、収納はめ合い面３１ａにネジ部２５ａが形成されている。また、収納はめ合 い面３１ａのネジ部２５ａのネジの谷３３ａの径の中の最大径Ｊがキャップはめ 合い面２４ａの内径Ｋより僅かに小さく設定されている。The eighth embodiment is shown in FIG. 9, which is an enlarged cross-sectional view of the same portion as that shown in FIG. 8, and has substantially the same structure as the seventh embodiment shown in FIGS. 7 and 8. Therefore, it has the same function as that of the seventh embodiment, but the following structure is different from that of the seventh embodiment. The cap fitting surface 24a is a right cylindrical inner peripheral surface, and the storage fitting surface 31a is a conical taper screw surface whose diameter is reduced toward the storage opening. The screw portion 25a is formed. Further, the maximum diameter J of the diameters of the thread troughs 33a of the threaded portion 25a of the housing fitting surface 31a is set to be slightly smaller than the inner diameter K of the cap fitting surface 24a.
【００４２】 ところで、キャップはめ合い面及び収納はめ合い面の構造は、上述した第７及 び第８の実施例以外に、以下に述べる構造も可能である。By the way, the cap fitting surface and the housing fitting surface can have the structures described below, in addition to the seventh and eighth embodiments described above.

Therefore, the container-shaped package is used instead of the bag-shaped package. The container-shaped package also employs the packaging sealing portion according to the present invention, so that the seventh and eighth embodiments are implemented. It is possible to have the same functionality as the example.
【００５１】 ところで、上述した第１〜第８の実施例では、本考案に係る包装用封止部を形 成する２部材のそれぞれのはめ合い面の形状が全て円柱状，直円筒状又は円錐状 とされているが、２部材のそれぞれのはめ合い面の形状は、円柱状又は円錐状に 限定されず、多角柱状，直多角筒状又は多角錘状等でもよい。By the way, in the above-mentioned first to eighth embodiments, the shapes of the respective fitting surfaces of the two members forming the packaging sealing portion according to the present invention are all cylindrical, right cylindrical or conical. However, the shape of the fitting surface of each of the two members is not limited to a cylindrical shape or a conical shape, and may be a polygonal pillar shape, a right polygonal cylinder shape, a polygonal pyramid shape, or the like.
【００５２】 また、上述した第１〜第８の実施例では、ネジ部の断面形状が全て図１０に示 される断面波型形状とされているが、ネジ部の断面形状は、断面波型形状に限定 されず、本考案に係る包装用封止部を形成する２部材が互いにはめ合わされたと きに、ネジ部を有しない部材のはめ合い面でネジ山が圧縮されて、ネジ部を有し ない部材のはめ合い面にネジ山が密接されていると共に、ネジ部のネジの谷とネ ジ部を有しない部材のはめ合い面との間に微小空隙が形成される断面形状であれ ばよい。従って、ネジ部の断面形状は、図１１に示される断面三角形状でもよく 、図１２に示されるネジの谷を平坦にした断面三角形状でもよく、そのほか断面 矩形形状や断面台形形状等でもよい。Further, in the above-described first to eighth embodiments, the cross-sectional shape of the screw portion is all the cross-sectional wavy shape shown in FIG. 10, but the cross-sectional shape of the screw portion is the cross-sectional wavy shape. The shape is not limited, and when the two members forming the packaging sealing portion according to the present invention are fitted to each other, the thread is compressed at the mating surface of the member having no threaded portion to have the threaded portion. If the thread is closely attached to the mating surface of the non-member, and if the cross-sectional shape is such that a minute gap is formed between the thread trough of the screw part and the mating surface of the member that does not have a screw part, Good. Therefore, the cross-sectional shape of the screw part may be a triangular cross-section shown in FIG. 11, a triangular cross-section shown in FIG. 12 in which the roots of the screws are flat, or a rectangular cross-section or a trapezoidal cross-section.
【００５３】 また、上述した第１〜第８の実施例ではネジ部が１条ネジとされているが、ネ ジ部は、１条ネジに限定されず、多条ネジでもよい。本考案に係る包装用封止部 のネジ部に多条ネジを採用した場合には、ネジ部を有する部材とネジ部を有しな い部材を互いにはめ合わせたときに、ネジ部を有しない部材のはめ合い面とネジ 部のネジの谷との間に形成される微小空隙の、ネジの谷に沿って走る螺旋の数が 多くなるので、微小空隙の目詰まり等により螺旋が閉塞されても、全ての螺旋が 閉塞されない限り、本考案に係る包装用封止部の内部と外部が連通されるので、 本考案に係る包装用封止部の内部の滅菌処理が可能になると共に、該包装用封止 部内の無菌状態を該包装用封止部の開封時まで保持することが可能になる。Further, in the above-described first to eighth embodiments, the screw portion is a single-thread screw, but the screw portion is not limited to a single-thread screw and may be a multiple-thread screw. When a multi-threaded screw is used for the thread part of the packaging sealing part according to the present invention, when the member having the thread part and the member having no thread part are fitted to each other, the thread part does not have the thread part. The number of spirals running along the thread troughs of the micro voids formed between the mating surface of the member and the thread troughs of the screw part increases, so the spirals are blocked by clogging of the micro voids, etc. However, as long as all the spirals are not closed, the inside and outside of the packaging sealing portion according to the present invention communicate with each other, so that the inside of the packaging sealing portion according to the present invention can be sterilized and It is possible to maintain the aseptic state in the packaging sealing portion until the packaging sealing portion is opened.
【００５４】 更に、上述した第１〜第８の実施例ではネジ部がはめ合い面全体に形成されて いるが、ネジ部は、はめ合い面の一部に形成されていてもよい。Further, in the above-described first to eighth embodiments, the threaded portion is formed on the entire fitting surface, but the threaded portion may be formed on a part of the fitting surface.
