栓体３１は、その中心軸線３１Ｌを容器筒壁部２２開口端部の中心軸線に一致させて容器筒壁部２２に螺着される。 The plug body 31 can be screwed onto the cylindrical wall portion 22 of the container 20 by screwing the inner screw portion 35a of the screwing wall portion 35 with the outer screw portion 22a on the outer periphery of the opening end portion of the cylindrical wall portion 22 of the container 20.
The plug body 31 is screwed to the container cylinder wall portion 22 with its center axis 31L aligned with the center axis of the opening end of the container cylinder wall portion 22.

図１〜図４に示すように、栓体３１の採取用突片３２は、栓体３１の挿入突部３４の栓体底壁部３４ｂの環状天壁部３３とは反対側の面３４ｄ（底面。以下、栓体底面、とも言う）の外周部から環状天壁部３３とは反対側へ延出している。
図１〜図３に示すように、採取用突片３２は、栓体３１側の支持片部３２ａと、この支持片部３２ａの先端（栓体３１とは反対側の端）から延出する採取片部３２ｂとを有する。 As shown in FIGS. 1 to 4, the sampling protrusion 32 of the plug 31 has a surface 34 d (on the opposite side of the annular top wall 33 of the plug bottom wall 34 b of the insertion protrusion 34 of the plug 31 ( A bottom surface (hereinafter also referred to as a bottom surface of the plug body) extends from the outer peripheral portion to the side opposite to the annular ceiling wall portion 33.
As shown in FIGS. 1 to 3, the sampling protrusion 32 extends from the support piece portion 32 a on the plug body 31 side and the tip of the support piece portion 32 a (the end opposite to the plug body 31). And a collection piece 32b.

支持片部３２ａは、栓体底面３４ｄ（具体的には栓体底壁部３４ｂ）の外周部の一部から栓体天面３３ｂとは反対の側へ突出（延出）されている。
図１〜図４に示す採取片付き栓体３０の採取用突片３２の支持片部３２ａは、栓体底面３４ｄ外周に沿う円弧状断面で栓体底面３４ｄから栓体３１軸線方向に沿って突出する円弧板状に形成されている。図１〜図４の支持片部３２ａは、栓体底面３４ｄからの突出方向全長にわたって一定断面寸法で突出している。この支持片部３２ａの栓体底面３４ｄ外周方向の断面寸法は、栓体底面３４ｄ外周の８分の１以上、半分以下であることが好ましく、栓体底面３４ｄ外周の６分の１以上、半分以下であることがより好ましい。 The support piece 32a protrudes (extends) from a part of the outer periphery of the plug bottom surface 34d (specifically, the plug bottom wall 34b) to the side opposite to the plug top surface 33b.
The support piece 32a of the sampling protrusion 32 of the plug 30 with the sampling piece shown in FIGS. 1 to 4 protrudes along the axial direction of the plug 31 from the plug bottom 34d in an arcuate section along the outer periphery of the plug bottom 34d. It is formed in a circular arc plate shape. 1 to 4 protrudes with a constant cross-sectional dimension over the entire length in the protruding direction from the plug bottom surface 34d. The cross-sectional dimension of the support piece portion 32a in the outer peripheral direction of the plug bottom surface 34d is preferably 1/8 or more and half or less of the outer periphery of the plug bottom surface 34d, and is 1/6 or more and half of the outer periphery of the plug bottom surface 34d. The following is more preferable.

図３、図４に示すように、採取片付き栓体３０の採取用突片３２の採取片部３２ｂは、支持片部３２ａ先端から湾曲断面形状で延出する円弧板状に形成されている。採取片部３２ｂの先端部以外の部分は、支持片部３２ａと同様の断面寸法で延在している。円弧板状の採取片部３２ｂは、その湾曲内周側の凹曲面が支持片部３２ａの湾曲内周側の凹曲面と接し、湾曲外周側の凸曲面が支持片部３２ａの湾曲外周側の凸曲面と接する向きの断面湾曲形状に形成されている。
採取片部３２ｂの基端部（栓体３１側の端部）の採取片部３２ｂ延在方向に垂直の断面は、栓体３１の前記底面の外周部に沿う円弧状に湾曲延在する。 As shown in FIGS. 3 and 4, the collection piece 32b of the collection protrusion 32 of the stopper 30 with the collection piece is formed in an arc plate shape extending in a curved cross-sectional shape from the tip of the support piece 32a. Portions other than the tip of the collection piece portion 32b extend with the same cross-sectional dimensions as the support piece portion 32a. The arcuate plate-shaped sampling piece portion 32b has a concave curved surface on the curved inner peripheral side in contact with a curved curved surface on the curved inner peripheral side of the support piece portion 32a, and a convex curved surface on the curved outer peripheral side on the curved outer peripheral side of the support piece portion 32a. It is formed in a cross-sectional curved shape in a direction in contact with the convex curved surface.
A cross section perpendicular to the extending direction of the collection piece portion 32b of the base end portion (end portion on the plug body 31 side) of the collection piece portion 32b extends in a circular arc shape along the outer peripheral portion of the bottom surface of the plug body 31.

図１、図２に示すように、採取片部３２ｂは、栓体底面３４ｄから突出する支持片部３２ａの先端（突端）から栓体３１とは反対の側へ向かって、栓体中心軸線３１Ｌに対して栓体中心軸線３１Ｌを介して反対の側（支持片部３２ａ先端とは反対の側）へ傾斜して延出している。
採取片部３２ｂは支持片部３２ａを介して栓体３１に対して支持されている。 As shown in FIGS. 1 and 2, the collection piece portion 32b is formed from the distal end (protrusion end) of the support piece portion 32a protruding from the plug bottom surface 34d toward the opposite side of the plug body 31 to the plug body central axis 31L. In contrast to the plug body central axis 31L, it extends to the opposite side (side opposite to the tip of the support piece 32a).
The collection piece portion 32b is supported with respect to the plug body 31 via the support piece portion 32a.

図１〜図４に示す採取片付き栓体３０の支持片部３２ａは、栓体底面３４ｄから栓体３１軸線方向に突出されている。このため、採取片部３２ｂは、栓体中心軸線３１Ｌのみならず、支持片部３２ａの栓体底面３４ｄからの突出方向に対しても傾斜して延在している。   The support piece 32a of the plug 30 with the collection piece shown in FIGS. 1 to 4 protrudes in the axial direction of the plug 31 from the plug bottom surface 34d. For this reason, the collection piece part 32b is inclined and extended not only with respect to the plug body central axis 31L but also with respect to the protruding direction from the plug bottom face 34d of the support piece part 32a.

図１〜図４に例示した実施形態の採取片付き栓体３０の支持片部３２ａの栓体底面３４ｄからの突出寸法は、採取片部３２ｂの延在寸法（支持片部３２ａからの延出長）に比べて小さい。支持片部３２ａの栓体底面３４ｄからの突出寸法は、例えば、採取片部３２ｂの延在寸法の１５〜３５％の寸法に確保される。
この採取片付き栓体３０の採取片部３２ｂの、支持片部３２ａの栓体底面３４ｄからの突出方向に対する傾斜角度θ（図１参照）は１０〜７０度であることが好ましく、３０〜６０度であることがより好ましい。 The protruding dimension of the support piece part 32a of the stopper 30 with the collection piece 30a of the embodiment illustrated in FIGS. 1 to 4 from the bottom face 34d is the extension dimension of the collection piece part 32b (extension length from the support piece part 32a). Is smaller than The projecting dimension of the support piece portion 32a from the bottom surface 34d of the stopper is ensured to be, for example, 15 to 35% of the extending dimension of the collection piece portion 32b.
The inclination angle θ (see FIG. 1) of the collection piece portion 32b of the collection piece-attached plug body 30 with respect to the protruding direction from the bottom surface 34d of the support piece portion 32a is preferably 10 to 70 degrees, and 30 to 60 degrees. It is more preferable that

図４、図５に示すように、採取片部３２ｂの先端部は、その採取片部３２ｂ延在方向に垂直の湾曲断面の延在方向寸法が採取片部３２ｂ先端側へ行くにしたがって縮小する先細り形状に形成されている。
先細り形状の採取片部３２ｂ先端部は、固形糞便等への採取片部３２ｂの突き刺しなどを容易にする利点がある。 As shown in FIGS. 4 and 5, the distal end portion of the collection piece portion 32b is reduced as the extension direction dimension of the curved cross section perpendicular to the extension direction of the collection piece portion 32b goes to the distal end side of the collection piece portion 32b. It is formed in a tapered shape.
The distal end of the tapered collection piece 32b has an advantage of facilitating the puncture of the collection piece 32b into solid feces or the like.

円弧板状の支持片部３２ａの栓体底面３４ｄ外周方向の断面寸法が半分以下であり、採取片部３２ｂの断面寸法も支持片部３２ａと同様であることは、採取用突片３２の樹脂成形を容易にする点、低コスト化の点で有利である。
なお、採取片部３２ｂの断面寸法は、必ずしも支持片部３２ａ断面寸法と同様である必要は無く、支持片部３２ａ断面寸法と異なっていても良い。採取用突片３２は、例えば、円弧板状の採取片部３２ｂの先端部以外の部分のその延在方向に垂直の湾曲断面の延在方向寸法が、円弧板状の支持片部３２ａのその湾曲断面の延在方向寸法よりも大きい構成も採用可能である。 The fact that the cross-sectional dimension in the outer peripheral direction of the plug bottom surface 34d of the arcuate plate-like support piece 32a is less than half and the cross-sectional dimension of the collection piece 32b is the same as that of the support piece 32a is that This is advantageous in terms of easy molding and cost reduction.
In addition, the cross-sectional dimension of the collection piece part 32b does not necessarily need to be the same as that of the support piece part 32a, and may differ from the cross-sectional dimension of the support piece part 32a. The sampling protrusion 32 has, for example, an extending direction dimension of a curved cross section perpendicular to the extending direction of a portion other than the tip end portion of the arc plate-shaped sampling piece portion 32b, and that of the arc plate-shaped support piece portion 32a. A configuration larger than the dimension of the curved cross section in the extending direction can also be adopted.

容器２０から取り外した状態の採取片付き栓体３０は、採取用突片３２及び栓体３１の挿入突部３４を容器開口部２１に挿入するとともに、栓体３１を容器筒壁部２２開口端部に対して相対回転させて、螺着壁部３５の内ねじ部３５ａを容器筒壁部２２開口端部の外ねじ部２２ａに螺合させることで、栓体３１を容器筒壁部２２開口端部に螺着できる。そして、採取片付き栓体３０は、容器筒壁部２２開口端部に螺着した栓体３１の容器筒壁部２２開口端部へのねじ込みによって、容器口縁部に環状天壁部３３の当接面３３ａを当接した状態で栓体３１を容器２０に締め付けることで、容器開口部２１を密閉できる。また、３３ａにシリコン、ゴム等の材質によるパッキン（密閉部材、密封部材、シール部材等）を挟むことにより、密閉性を高めることも可能である。
容器筒壁部２２開口端部に螺着された栓体３１は、容器筒壁部２２開口端部に対してねじ込み時とは逆向きに回転操作することで、容器２０から離脱させることができる。 The stopper 30 with the sampling piece removed from the container 20 inserts the sampling protrusion 32 and the insertion protrusion 34 of the stopper 31 into the container opening 21, and the stopper 31 is opened at the opening of the container cylinder wall 22. And the inner threaded portion 35a of the threaded wall portion 35 is screwed into the outer threaded portion 22a of the opening end portion of the container tube wall portion 22 so that the plug 31 is opened at the open end of the container tube wall portion 22. Can be screwed to the part. Then, the stopper 30 with the collection piece is screwed into the opening end of the container cylinder wall 22 of the stopper 31 screwed to the opening end of the container cylinder wall 22 so that the annular top wall 33 is pressed against the container mouth. The container opening 21 can be sealed by tightening the stopper 31 to the container 20 with the contact surface 33a in contact. Further, it is possible to enhance the sealing performance by sandwiching packing 33 (a sealing member, a sealing member, a sealing member, etc.) made of a material such as silicon or rubber in 33a.
The stopper 31 screwed into the opening end of the container tube wall 22 can be detached from the container 20 by rotating the container 31 against the opening of the container tube wall 22 in the direction opposite to that during screwing. .

なお、採取片付き栓体３０の採取用突片３２は、採取片付き栓体３０の栓体３１の容器筒壁部２２開口端部へのねじ込み、締め付けによって容器開口部２１を密閉したときに、その先端が容器２０の底壁２３近傍に達する延在寸法を以て形成されている。
また、採取片付き栓体３０の栓体３１によって容器開口部２１を密閉したとき、採取片付き栓体３０の採取用突片３２の先端は、容器筒壁部２２の中心軸線付近（容器筒壁部２２中心軸線に接する位置あるいはその近傍）に配置される。 When the container opening 21 is hermetically sealed by screwing and tightening the stopper 31 of the stopper 30 with the collection piece into the opening end of the container cylinder wall 22, The tip is formed with an extension dimension that reaches the vicinity of the bottom wall 23 of the container 20.
When the container opening 21 is sealed by the stopper 31 of the stopper 30 with the sampling piece, the tip of the sampling protrusion 32 of the stopper 30 with the sampling piece is near the center axis of the container cylinder wall 22 (the container cylinder wall 22 at or near the center axis).

図１、図２に例示した採取片付き栓体３０の栓体３１は、環状天壁部３３から栓体天面３３ｂとは反対側に突出する密閉補助突壁３６を有する。密閉補助突壁３６は、栓体中心軸線３１Ｌを中心とするリング状に形成されている。但し、密閉補助突壁３６は、螺着壁部３５に比べて径小であり、螺着壁部３５から栓体中心軸線３１Ｌ側へ離隔させて形成されている。環状天壁部３３の当接面３３ａは、環状天壁部３３の栓体天面３３ｂとは反対の側において密閉補助突壁３６と螺着壁部３５との間に位置している。
密閉補助突壁３６と螺着壁部３５との間には、栓体３１によって容器開口部２１を密閉したときに容器筒壁部２２開口端部が挿入される。密閉補助突壁３６は、密閉補助突壁３６と螺着壁部３５との間に挿入された容器筒壁部２２開口端部内周面に当接して、容器２０内の試料４２が容器口縁部と栓体３１（具体的には環状天壁部３３）との間から漏出することを防ぐべく、栓体３１による容器開口部２１の密閉性を高める役割を果たす。
なお、採取片付き栓体は、密閉補助突壁３６を有していない構成も採用可能である。 The stopper 31 of the stopper 30 with a collection piece illustrated in FIGS. 1 and 2 has a sealing auxiliary protruding wall 36 that protrudes from the annular top wall 33 to the side opposite to the stopper top surface 33b. The sealing auxiliary protruding wall 36 is formed in a ring shape centered on the plug body central axis 31L. However, the sealing auxiliary protruding wall 36 is smaller in diameter than the screwing wall part 35 and is formed to be separated from the screwing wall part 35 toward the plug body central axis 31L. The contact surface 33 a of the annular ceiling wall 33 is located between the auxiliary sealing projection wall 36 and the screwing wall 35 on the opposite side of the annular ceiling wall 33 from the plug top surface 33 b.
Between the sealing auxiliary projecting wall 36 and the screwing wall portion 35, the container cylindrical wall portion 22 opening end is inserted when the container opening portion 21 is sealed by the stopper 31. The sealing auxiliary protruding wall 36 abuts on the inner peripheral surface of the opening end of the container cylinder wall portion 22 inserted between the sealing auxiliary protruding wall 36 and the screwing wall portion 35, so that the sample 42 in the container 20 is in the container lip. In order to prevent leakage from between the opening portion and the plug body 31 (specifically, the annular ceiling wall section 33), it plays a role of improving the sealing performance of the container opening 21 by the plug body 31.
In addition, the structure which does not have the sealing auxiliary | assistant protrusion wall 36 is also employable for the stopper with a collection piece.

試料採取用具１０の採取片付き栓体３０は、容器２０から取り外した状態（離脱させた状態）で糞便等の試料を採取に用いられる。容器２０から取り外した状態採取片付き栓体３０による試料採取は、例えば、その使用者が栓体３１を把持した手指で操作することで、採取片部３２ｂに糞便等の試料を採取する。
試料採取用具１０は、試料採取後の採取片付き栓体３０の採取用突片３２を採取した試料とともに容器開口部２１に挿入し、容器筒壁部２２開口端部に螺着した栓体３１を容器２０に締め付けて容器開口部２１を密閉することで、採取した試料を容器２０に収容、保管できる。 The stopper 30 with the collection piece of the sample collection tool 10 is used for collecting a sample such as stool in a state of being removed from the container 20 (a state of being detached). Sample collection by the plug 30 with the state collection piece removed from the container 20 is performed by, for example, operating the user with a finger holding the plug 31 and collecting a sample such as feces in the collection piece 32b.
The sample collection tool 10 includes a plug 31 that is inserted into the container opening 21 together with the collected sample, and the plug 31 that is screwed into the opening end of the container tube wall 22. By tightening the container 20 and sealing the container opening 21, the collected sample can be stored and stored in the container 20.

採取片付き栓体３０の採取片部３２ｂに採取された固形状の糞便等の試料は、主として、容器筒壁部２２と容器２０に挿入した採取用突片３２の採取片部３２ｂとの間に配置された状態にて、試料採取用具１０内に収容される。
試料採取用具は、図１、図２等に示す試料採取用具１０について採取片付き栓体３０の採取片部３２ｂのみを変更し、栓体３１によって容器開口部２１を密閉したときに採取片部３２ｂのその先端部よりも基端側部分が容器筒壁部２２の中心軸線と交差し、採取片部３２ｂ先端が容器筒壁部２２内周面に近接配置される構成（以下、採取部先端近接形採取用具、とも言う）も採り得る。但し、図１、図２等に示す試料採取用具１０であれば、栓体３１によって容器開口部２１を密閉したときの採取片部３２ｂと容器筒壁部２２内周面との間のスペースを採取部先端近接形採取用具に比べて大きく確保できる。このため、栓体３１によって容器開口部２１を密閉したときに採取用突片３２先端が容器筒壁部２２の中心軸線付近に配置される構成の試料採取用具１０は、採取部先端近接形採取用具に比べて試料収容量の増大に有利である。 A sample of solid stool or the like collected in the collection piece portion 32b of the stopper 30 with the collection piece is mainly between the collection piece portion 32b of the collection projection piece 32 inserted into the container cylinder wall portion 22 and the container 20. The sample is collected and stored in the sample collection tool 10.
The sample collection tool is a sample collection part 32b that is obtained when only the collection piece 32b of the stopper 30 with the collection piece is changed from the sample collection tool 10 shown in FIGS. 1 and 2 and the container opening 21 is sealed by the stopper 31. A configuration in which the base end side portion of the tip of the tube intersects the central axis of the container tube wall portion 22 and the tip of the collection piece portion 32b is disposed close to the inner peripheral surface of the container tube wall portion 22 (hereinafter referred to as the proximity of the tip of the collection portion) (Also known as a shape collection tool). However, in the case of the sample collection tool 10 shown in FIGS. 1 and 2, the space between the collection piece portion 32 b and the inner peripheral surface of the container cylindrical wall portion 22 when the container opening 21 is sealed with the stopper 31 is provided. It is possible to secure a larger size than that of the sampling part tip proximity type sampling tool. For this reason, when the container opening 21 is sealed by the stopper 31, the sample collection tool 10 having a configuration in which the tip of the collection protrusion 32 is arranged near the central axis of the container cylinder wall portion 22 is provided with the collection portion tip proximity collection. It is advantageous in increasing the sample capacity compared to the tool.

採取部先端近接形採取用具の支持片部３２ａの栓体底面３４ｄからの突出寸法は、例えば、採取片部３２ｂの延在寸法の５〜３５％の寸法に確保される。
採取部先端近接形採取用具の採取片部３２ｂの、支持片部３２ａの栓体底面３４ｄからの突出方向に対する傾斜角度θ（図１参照）は１０〜７０度であることが好ましく、３０〜６０度であることがより好ましい。 The protruding dimension from the bottom surface 34d of the support piece 32a of the sampling part tip proximity type collecting tool is ensured to be, for example, 5 to 35% of the extension dimension of the collecting piece part 32b.
The inclination angle θ (see FIG. 1) of the collection piece portion 32b of the collection portion tip proximity collection tool with respect to the protruding direction of the support piece portion 32a from the plug bottom surface 34d is preferably 10 to 70 degrees, and preferably 30 to 60 degrees. More preferably.

試料が糞便である場合、容器２０から取り外した状態の採取片付き栓体３０による試料採取は、固形状あるいは粘土状の糞便に突き刺した採取片部３２ｂへの取り出し、糞便が載置された載置面に沿って移動させた採取片部３２ｂへの掬い上げ（図６参照）、等によって実現できる。   When the sample is stool, the sample collection by the stopper 30 with the collection piece removed from the container 20 is taken out to the collection piece portion 32b stabbed into the solid or clay-like stool and placed on which the stool is placed. It can be realized by scooping up the collection piece 32b moved along the surface (see FIG. 6) or the like.

図６は、本発明の試料採取方法を説明する図であり、とくに水平方向に延在する載置面４１上にある試料４２を採取片部３２ｂに掬い上げて採取する掬い上げ操作を説明する図である。図６に示すように、掬い上げ操作は、容器２０から取り外した状態の採取片付き栓体３０を、その栓体中心軸線３１Ｌが採取片部３２ｂ側に比べて栓体３１側の方が載置面４１からの離隔距離が大きくなるように載置面４１に対して傾斜した向きで、採取片部３２ｂ先端を載置面４１に当接させて使用する。しかも、採取片付き栓体３０は、栓体底壁部３４ｂの採取用突片３２基端部と連続する部分が栓体底壁部３４ｂにおける最下部に位置する向きで使用する。
そして、掬い上げ操作は、採取片付き栓体３０を上述の向きで採取片部３２ｂ先端を載置面４１に当接させた状態を保ったまま載置面４１に沿って移動させ、載置面４１から試料４２を掬い上げて採取する。試料４２は採取片部３２ｂの凹曲面側に採取する。 FIG. 6 is a diagram for explaining the sample collecting method of the present invention, and in particular, a scooping operation for picking up and collecting the sample 42 on the mounting surface 41 extending in the horizontal direction onto the collection piece 32b. FIG. As shown in FIG. 6, the scooping operation is performed by placing the stopper 30 with the sampling piece removed from the container 20 so that the stopper central axis 31L is closer to the stopper 31 than the sampling piece 32b. The tip of the collection piece 32b is brought into contact with the mounting surface 41 in a direction inclined with respect to the mounting surface 41 so that the separation distance from the surface 41 is increased. Moreover, the stopper 30 with the collection piece is used in such a direction that the portion of the stopper bottom wall portion 34b that is continuous with the base end portion of the collection protrusion 32 is located at the lowermost portion of the stopper bottom wall portion 34b.
The scooping operation is performed by moving the stopper 30 with the sampling piece along the mounting surface 41 while keeping the tip of the sampling piece portion 32b in contact with the mounting surface 41 in the above-described direction. A sample 42 is picked up from 41 and collected. The sample 42 is collected on the concave curved surface side of the collection piece 32b.

図６の試料４２の掬い上げ操作にあっては、採取片付き栓体３０の栓体３１（具体的には螺着壁部３５）や栓体３１を把持する使用者の手指が載置面４１上の試料４２に接触して試料が付着することを防ぐには、栓体３１を載置面４１から上方に離隔させて支持した状態を保つ。なお、試料は載置面４１の広範囲に分散して存在することもある。栓体３１を載置面４１から上方に離隔させて支持することは、栓体３１（具体的には螺着壁部３５）や栓体３１を把持する使用者の手指が載置面４１の広範囲に分散して存在する試料に接触して試料が付着することを防ぐ。
その一方、掬い上げ操作では、採取片部３２ｂ上への試料採取のために、採取片部３２ｂを載置面４１に平行に近付けて試料の掬い上げを行ないたいケースがある。 In the scooping operation of the sample 42 in FIG. 6, the stopper 31 (specifically, the screwing wall portion 35) of the stopper 30 with the collection piece and the finger of the user holding the stopper 31 are placed on the mounting surface 41. In order to prevent the sample from adhering to the upper sample 42, the plug 31 is separated from the mounting surface 41 and supported. Note that the sample may be dispersed over a wide range of the mounting surface 41. Supporting the plug body 31 by separating it upward from the placement surface 41 means that the finger of the user who holds the plug body 31 (specifically, the screwing wall portion 35) or the plug body 31 is placed on the placement surface 41. The sample is prevented from coming into contact with a sample that is dispersed in a wide range.
On the other hand, in the scooping operation, there is a case where the sample is desired to be scooped up by bringing the collection piece 32b close to the placement surface 41 in order to collect the sample on the collection piece 32b.

採取片付き栓体３０の採取用突片３２は栓体底壁部３４ｂの外周部から延出している。
ここで、採取片付き栓体３０について、採取用突片３２が栓体底壁部３４ｂ（栓体底面３４ｄ）の中央部から延出するように改変した構成（以下、採取部中央延出形栓体、とも言う）との対比を説明する。
採取片付き栓体３０は、栓体底壁部３４ｂの採取用突片３２基端部と連続する部分が栓体底壁部３４ｂにおける最下部に位置する向きで掬い上げ操作に使用することで、採取部中央延出形栓体に比べて、栓体３１の載置面４１からの距離（高さ）を大きく（高く）確保できる。つまり、採取片付き栓体３０は、栓体底壁部３４ｂの採取用突片３２基端部と連続する部分が栓体底壁部３４ｂにおける最下部に位置する向きで掬い上げ操作に使用するとき、採取片部３２ｂの載置面４１に対する傾斜角度を同じにした採取部中央延出形栓体に比べて、栓体３１の載置面４１からの距離（高さ）を大きく（高く）確保できる。 The sampling protrusion 32 of the stopper 30 with the sampling piece extends from the outer periphery of the bottom wall 34b of the stopper.
Here, the plug 30 with the collection piece is modified so that the collection protrusion 32 extends from the central portion of the plug bottom wall portion 34b (the plug bottom surface 34d) (hereinafter, the collection portion central extension type plug). (Also called body).
The stopper 30 with the sampling piece is used for a scooping operation in a direction in which the base end portion of the sampling bottom 32 of the stopper bottom wall 34b is located at the lowermost part of the stopper bottom wall 34b, The distance (height) from the mounting surface 41 of the plug body 31 can be ensured to be large (high) as compared with the collection part central extension type plug body. That is, when the stopper 30 with the sampling piece is used for a scooping operation in a direction in which the base end of the sampling protrusion 32 of the stopper bottom wall 34b is located at the lowermost part of the stopper bottom wall 34b. The distance (height) from the mounting surface 41 of the plug body 31 is ensured to be larger (higher) than that of the sampling section central extension type plug body having the same inclination angle with respect to the mounting surface 41 of the sampling piece portion 32b. it can.

このため、採取片付き栓体３０は、採取部中央延出形栓体に比べて、掬い上げ操作の際に、栓体３１や栓体３１を把持する使用者の手指が載置面４１上の試料４２に接触して試料が付着することを防ぐ点で有利である。採取片付き栓体３０は、採取部中央延出形栓体に比べて、掬い上げ操作による試料採取の作業性向上に有利である。   For this reason, the stopper 30 with the sampling piece has the stopper 31 and the user's finger holding the stopper 31 on the mounting surface 41 during the scooping operation compared to the central extension extending stopper of the sampling part. This is advantageous in that it prevents the sample from adhering to the sample 42. The stopper 30 with the collection piece is more advantageous for improving the workability of collecting the sample by the scooping operation than the central extension plug body of the collection part.

特許文献１に記載の試料採取用具（試料採取用器具）の取っ手部は、特許文献１の図２、図６を参照して判るように、密閉栓における管状体の開口を密閉したときに管状体内側空間に臨む面の中央部から延出されている。
採取片付き栓体３０は、特許文献１に記載の試料採取用具に比べて、掬い上げ操作による試料採取の作業性向上に有利である。 The handle portion of the sample collection tool (sample collection device) described in Patent Document 1 is tubular when the opening of the tubular body in the sealing plug is sealed, as can be seen with reference to FIGS. 2 and 6 of Patent Document 1. It extends from the center of the surface facing the body space.
Compared with the sample collection tool described in Patent Document 1, the stopper 30 with the collection piece is advantageous in improving workability of sample collection by the scooping operation.

特許文献１に記載の試料採取用具の匙部の取っ手部先端からの延出寸法は、取っ手部の密封栓からの延出寸法に比べて格段に小さい。これに対して、支持片部３２ａの栓体底面３４ｄからの突出寸法が採取片部３２ｂの延在寸法に比べて小さい採取片付き栓体３０は、採取片部３２ｂのサイズの大型化、試料採取量の増大に有利である。また、採取片付き栓体３０は、支持片部３２ａの栓体底面３４ｄからの突出寸法が採取片部３２ｂの延在寸法の１５〜３５％であっても、掬い上げ操作による試料採取の作業性を良好に確保できる。   The extension dimension from the handle | tip part of the handle part of the collar part of the sampling tool of patent document 1 is remarkably small compared with the extension dimension from the sealing stopper of a handle part. On the other hand, the stopper 30 with the sampling piece whose protrusion dimension from the stopper bottom surface 34d of the support piece 32a is smaller than the extension dimension of the sampling piece part 32b is increased in size and sampling of the sampling piece part 32b. It is advantageous to increase the amount. In addition, the stopper 30 with the sampling piece has the workability of sampling by the scooping operation even if the protruding dimension of the support piece 32a from the bottom surface 34d of the supporting piece 32a is 15 to 35% of the extension dimension of the sampling piece 32b. Can be secured satisfactorily.

なお、特許文献１に記載の試料採取用具は、その構成上、仮に、匙部の取っ手部先端からの延出寸法を、取っ手部の密封栓からの延出寸法に比べて大きくすると、水平方向に延在する載置面４１上の試料を掬い上げる掬い上げ操作の際に、密閉栓の載置面４１からの距離（高さ）が小さくなる。その結果、特許文献１に記載の試料採取用具は、掬い上げ操作による試料採取の作業性が低下する。   In addition, the sample collection tool described in Patent Document 1 has a horizontal direction when the extension dimension from the front end of the handle part of the collar part is larger than the extension dimension from the sealing plug of the handle part. The distance (height) of the sealing plug from the mounting surface 41 is reduced during the scooping operation for scooping up the sample on the mounting surface 41 extending to the surface. As a result, the sample collection tool described in Patent Document 1 has poor sample collection workability due to the scooping operation.

採取片付き栓体３０の操作は、例えば、使用者が複数本の手指で栓体３１の外周部（具体的には螺着壁部３５）のみを把持して行なうが、これに限定されない。採取片付き栓体３０の操作は、例えば、栓体３１の栓体凹部３４ｃに差し入れた手指を利用して、複数の手指によって、栓体３１の螺着壁部３５外側面と栓体凹部３４ｃとの間に位置する部分を把持して行なっても良い。   The operation of the stopper 30 with the collection piece is performed, for example, by the user holding only the outer peripheral portion (specifically, the screwing wall portion 35) of the stopper 31 with a plurality of fingers, but is not limited thereto. The operation of the stopper 30 with the sampling piece is performed by using, for example, fingers inserted into the stopper recess 34c of the stopper 31 and by using a plurality of fingers, the outer surface of the screwing wall 35 of the stopper 31 and the stopper recess 34c. You may hold | grip the part located between.

例えば採取片付き栓体３０を狭隘な作業空間に差し入れて掬い上げ操作によって採取採取するとき、栓体３１の下側や左右両側に手指を回り込ませることが難しい場合が生じ得る。しかしながら、採取片付き栓体３０は、掬い上げ操作の際に、栓体３１の栓体凹部３４ｃに差し入れた手指を利用して、栓体３１の螺着壁部３５外側面と栓体凹部３４ｃとの間に位置する部分を手指で把持することで、狭隘な作業空間における掬い上げ操作を効率良く行うことも可能である。   For example, when the plug 30 with the collection piece is inserted into a narrow work space and collected by a scooping operation, it may be difficult to wrap the fingers under the plug 31 or both left and right sides. However, the stopper 30 with the sampling piece is used for the operation of scooping up the outer surface of the screwing wall 35 of the stopper 31 and the stopper recess 34c using the fingers inserted into the stopper recess 34c of the stopper 31. It is also possible to efficiently perform a scooping operation in a narrow work space by gripping a portion located between the fingers.

次に、本発明の試料採取用具１０を使用した試料の検査方法の発明について説明する。本発明の試料の検査方法においては、まず図６に示した試料の採取方法を実行する。具体的には、例えば図６において試料４２が被験者の糞便であるとすると、図６に記載された態様に従って採取片付き栓体３０を使用し、採取片部３２ｂによって試料４２（糞便）を掬い上げて採取する。
その状態で採取片付き栓体３０を、採取用突片３２及び栓体３１の挿入突部３４を容器開口部２１に挿入するとともに、栓体３１を容器筒壁部２２開口端部に対して相対回転させて、螺着壁部３５の内ねじ部３５ａを容器筒壁部２２開口端部の外ねじ部２２ａに螺合させ、栓体３１を容器筒壁部２２開口端部に螺着する。これにより試料採取用具１０は、図２の状態になる。ただし図２では図示されていないが、容器２０の内部空間には、採取片部３２ｂに採取した試料４２（糞便）が存在している。
この状態で、採取した試料４２（糞便）を、例えば、特許第５２６４２３９号公報に記載されるスギ花粉症の補助検査に供することができる。この場合は、採取した試料４２（糞便）の中のバクテロイデス・ユニフォルミスおよびバクテロイデス・カッカエからなる群より選択される１種以上の菌種の菌数が、試料４２（糞便）の１ｇ当たり１００万未満である場合に、被験者がスギ花粉症に罹患している可能性が高いと判断する。 Next, the invention of the sample inspection method using the sampling tool 10 of the present invention will be described. In the sample inspection method of the present invention, first, the sample collection method shown in FIG. 6 is executed. Specifically, for example, in FIG. 6, if the sample 42 is the stool of the subject, the stopper with a collection piece 30 is used according to the embodiment described in FIG. 6, and the sample 42 (feces) is scooped up by the collection piece portion 32 b. To collect.
In that state, the stopper 30 with the sampling piece is inserted into the container opening 21 with the sampling protrusion 32 and the insertion protrusion 34 of the stopper 31, and the stopper 31 is relative to the opening end of the container cylinder wall 22. By rotating, the inner threaded portion 35a of the threaded wall portion 35 is screwed into the outer threaded portion 22a at the opening end portion of the container tube wall portion 22, and the stopper 31 is screwed into the opening end portion of the container tube wall portion 22. Thereby, the sampling tool 10 is in the state shown in FIG. However, although not shown in FIG. 2, the sample 42 (feces) collected in the collection piece 32 b exists in the internal space of the container 20.
In this state, the collected sample 42 (feces) can be subjected to an auxiliary test for cedar pollinosis described in, for example, Japanese Patent No. 5264239. In this case, the number of bacteria of one or more bacterial species selected from the group consisting of Bacteroides Uniformis and Bacteroides kaykae in the collected sample 42 (stool) is less than 1 million per gram of sample 42 (stool). In this case, it is determined that there is a high possibility that the subject is suffering from cedar pollinosis.

以上のように、本発明の試料の採取方法は様々な検査方法に利用することが可能であり、例えば、試料４２が人の糞便であれば、糞便中の水分含量、アミノ酸類や脂肪酸等の腸内代謝産物（腸内分泌物を含む）の成分組成、細菌学的方法（培養法を含む）またはPCR法、次世代シーケンサーなどによる菌叢、色査計などによる色味等の検査に供することができる。また、試料４２が食品であれば、栄養成分組成、細菌数などの衛生試験、環境ホルモン測定等の検査に供することができる。さらに試料４２が土壌、泥等であれば、環境試験等の検査に供することができる。   As described above, the sample collection method of the present invention can be used in various inspection methods. For example, if the sample 42 is human stool, the water content in stool, amino acids, fatty acids, etc. Ingredient composition of intestinal metabolites (including intestinal secretion), bacteriological methods (including culture methods) or PCR methods, bacterial flora by next-generation sequencers, etc. Can do. Moreover, if the sample 42 is a food, it can be used for tests such as hygiene tests such as nutrient composition, bacteria count, and environmental hormone measurement. Furthermore, if the sample 42 is soil, mud, etc., it can be used for inspections such as environmental tests.
