Description

本発明は、容器に取り付けられるキャップに関する。 The present invention relates to a cap attached to a container.

従来、この種のキャップとしては、例えば図３０，図３１に示すように、容器に取り付けられる中栓１０１と、回転することにより中栓１０１に着脱自在なねじ式の蓋１０２とを有するものがある。中栓１０１は、中栓本体１０３と、中栓本体１０３に第１弱化部１０４を介して離脱可能に設けられた離脱部１０５とを有している。 Heretofore, as this type of cap, for example, as shown in FIGS. 30 and 31, one having an inner plug 101 attached to a container and a screw-type lid 102 detachable from the inner plug 101 by rotating it. is there. The inner plug 101 includes an inner plug body 103 and a release portion 105 provided on the inner plug body 103 so as to be removable via the first weakening portion 104.

また、蓋１０２は、蓋本体１０６と、蓋本体１０６に第２弱化部１０７を介して離脱可能に設けられた封印帯１０８とを有している。
離脱部１０５の外周には、所定方向に傾いた三角形状の複数の第１歯部１０９が設けられ、蓋本体１０６の内周には、所定方向に傾いた突片状の複数の第２歯部１１０が設けられている。これら第１歯部１０９の相互間と第２歯部１１０の相互間とにはそれぞれ、蓋１０２の回転方向において空転領域（図示省略）が設けられている。 Further, the lid 102 has a lid main body 106 and a sealing band 108 provided on the lid main body 106 so as to be detachable via the second weakening portion 107.
A plurality of triangular first teeth 109 inclined in a predetermined direction are provided on the outer periphery of the detachment portion 105, and a plurality of second teeth in a protrusion shape are inclined on the inner periphery of the lid body 106. The part 110 is provided. Between the first teeth 109 and between the second teeth 110, idle areas (not shown) are provided in the rotational direction of the lid 102.

尚、第１歯部１０９と第２歯部１１０とで一方のラチェット機構１１２が構成されており、蓋１０２を開方向Ｏへ回しても、一方のラチェット機構１１２は、空転領域（図示省略）の範囲内で、第１歯部１０９と第２歯部１１０との歯合を起こさない。 In addition, one ratchet mechanism 112 is comprised by the 1st tooth part 109 and the 2nd tooth part 110, and even if it rotates lid 102 in the opening direction O, one ratchet mechanism 112 is an idle rotation area (illustration abbreviation) In the range of (1), the first tooth portion 109 and the second tooth portion 110 do not mesh.

また、中栓本体１０３の外周には、所定方向に傾いた板状の複数の第３歯部１１３が設けられ、封印帯１０８の内周には、所定方向に傾いた突片状の複数の第４歯部１１４が設けられている。第３歯部１１３と第４歯部１１４とで他方のラチェット機構１１５が構成されており、封印帯１０８が蓋本体１０６に設けられている状態で、蓋１０２を開方向Ｏへ回した場合、封印帯１０８は開方向Ｏへ回転することができない。 In addition, a plurality of plate-like third tooth portions 113 inclined in a predetermined direction is provided on the outer periphery of the inner plug body 103, and a plurality of protrusion-like pieces inclined in the predetermined direction is provided on the inner periphery of the sealing band 108. A fourth toothed portion 114 is provided. When the lid 102 is turned in the opening direction O in a state in which the other ratchet mechanism 115 is configured by the third tooth portion 113 and the fourth tooth portion 114 and the sealing band 108 is provided on the lid body 106, The sealing band 108 can not rotate in the opening direction O.

以下、上記構成における作用を説明する。
離脱部１０５が中栓本体１０３に設けられ且つ封印帯１０８が蓋本体１０６に設けられている未使用状態において、蓋１０２を中栓１０１に取り付ける場合、蓋１０２を閉方向Ｓへ回しながら、蓋１０２側の螺条１１７を中栓１０１側の螺条１１８に螺合する。この際、蓋１０２と一体に、第２歯部１１０が閉方向Ｓへ移動して第１歯部１０９をその斜面に沿って乗り越えるとともに、第４歯部１１４が閉方向Ｓへ移動して第３歯部１１３を押し退けながら乗り越える。これにより、蓋１０２を閉方向Ｓへ回して中栓１０１に取り付けることができる。 Hereinafter, the operation in the above configuration will be described.
When the lid 102 is attached to the inner plug 101 in an unused state in which the detachment portion 105 is provided in the inner plug body 103 and the sealing band 108 is provided in the lid main body 106, the lid 102 is rotated in the closing direction S. The screw 117 on the 102 side is screwed into the screw 118 on the inner plug 101 side. At this time, the second tooth portion 110 moves in the closing direction S integrally with the lid 102 and rides over the first tooth portion 109 along the slope, and the fourth tooth portion 114 moves in the closing direction S and (3) Get over the teeth 113 while pushing it away. Thereby, the lid 102 can be turned in the closing direction S and attached to the plug 101.

その後、蓋１０２を中栓１０１から取り外して、容器の内容物を使用する場合、蓋１０２を開方向Ｏへ回す。この際、一方のラチェット機構１１２では、空転領域の範囲内で、第２歯部１１０が開方向Ｏにおいて第１歯部１０９に歯合しないのに対して、他方のラチェット機構１１５では、第４歯部１１４が開方向Ｏにおいて第３歯部１１３に歯合しているため、封印帯１０８は蓋本体１０６の開方向Ｏの回動に追従することができず、先ず、第２弱化部１０７が破断して蓋本体１０６が封印帯１０８から離脱する。 Thereafter, the lid 102 is removed from the plug 101, and the lid 102 is turned in the opening direction O when the contents of the container are used. At this time, in one ratchet mechanism 112, the second tooth portion 110 does not mesh with the first tooth portion 109 in the opening direction O within the range of the idling region, while the other ratchet mechanism 115 Since the toothed portion 114 meshes with the third toothed portion 113 in the opening direction O, the sealing band 108 can not follow the pivoting of the lid main body 106 in the opening direction O. First, the second weakened portion 107 Is broken and the lid body 106 is separated from the sealing band 108.

その後、第２歯部１１０が空転領域の範囲を開方向Ｏに移動して第１歯部１０９に歯合するため、第１弱化部１０４が破断して離脱部１０５が中栓本体１０３から離脱する。これにより、中栓本体１０３に注出口が形成され、容器の内容物を注出口から注出することができる。 After that, the second tooth portion 110 moves in the open direction O in the opening direction O and meshes with the first tooth portion 109, so the first weakening portion 104 breaks and the separating portion 105 separates from the inner plug body 103 Do. Thus, a spout is formed in the inside plug body 103, and the contents of the container can be spouted from the spout.

尚、上記のようなキャップは例えば下記特許文献１に記載されている。 The above-mentioned cap is described, for example, in Patent Document 1 below.

しかしながら上記の従来形式では、未使用状態において、蓋１０２を閉方向Ｓへ回して中栓１０１に取り付けるため、第３歯部１１３と第４歯部１１４とが閉方向Ｓにおいて歯合せず且つ開方向Ｏにおいて歯合するように、第３歯部１１３と第４歯部１１４とでラチェット機構１１５を構成する必要があり、第３歯部１１３と第４歯部１１４との形状が限定され、設計が制限された。同様に、第１歯部１０９と第２歯部１１０についても、ラチェット機構１１２を構成する必要があるため、形状が限定され、設計が制限された。 However, in the above-described conventional type, the third tooth 113 and the fourth tooth 114 do not mesh in the closing direction S and are open because the lid 102 is rotated in the closing direction S and attached to the plug 101 in the unused state. It is necessary to configure the ratchet mechanism 115 with the third tooth 113 and the fourth tooth 114 so as to mesh in the direction O, and the shapes of the third tooth 113 and the fourth tooth 114 are limited, The design was limited. Similarly, since it is necessary to configure the ratchet mechanism 112 for the first tooth 109 and the second tooth 110, the shape is limited and the design is limited.

本第４発明におけるキャップは、容器に取り付けられる中栓と、回転することにより中栓に着脱自在なねじ式の蓋とを有し、
中栓は、中栓本体と、中栓本体に第１弱化部を介して離脱可能に設けられた離脱部とを有し、
蓋は、蓋本体と、蓋本体に第２弱化部を介して離脱可能に設けられた封印帯とを有し、
蓋を開方向へ回すことにより、第２弱化部が破断して蓋本体が封印帯から離脱し、第１弱化部が破断して離脱部が中栓本体から離脱して、中栓本体に注出口が形成されるキャップであって、
離脱部に第１係合部が設けられているとともに蓋本体に第２係合部が設けられ、
中栓本体に第３係合部が設けられているとともに封印帯に第４係合部が設けられ、
第１係合部と第２係合部ならびに第３係合部と第４係合部がそれぞれ蓋の開方向において係合可能であり、
離脱部が中栓本体に設けられ且つ封印帯が蓋本体に設けられている未使用状態において、蓋を軸心方向に移動させて中栓に取付可能であり、
未使用状態において蓋を中栓に取付けた後、蓋を開方向へ回した際、先ず、第４係合部が開方向において第３係合部に係合し、第２弱化部が破断し、その後、第２係合部が開方向において第１係合部に係合し、第１弱化部が破断するものである。 The cap in the fourth aspect of the present invention has a plug inside the container attached to the container, and a screw-type lid that is removable from the plug by turning.
The inside plug includes a inside plug body and a disengaging part provided detachably on the inside plug body via the first weakening part,
The lid has a lid body, and a sealing band removably provided on the lid body via the second weakening portion,
By turning the lid in the opening direction, the second weakening part is broken and the lid body is separated from the sealing band, and the first weakening part is broken and the separated part is separated from the inside plug body and poured into the inside plug body. A cap on which the outlet is formed,
A first engaging portion provided at the disengaging portion and a second engaging portion provided at the lid body;
A third engaging portion is provided on the inner plug body and a fourth engaging portion is provided on the sealing band,
The first engagement portion and the second engagement portion and the third engagement portion and the fourth engagement portion are engageable in the opening direction of the lid,
In an unused state in which the disengaging portion is provided on the inside plug body and the sealing band is provided on the lid body, the lid can be moved in the axial direction and attachable to the inside plug,
After attaching the lid to the inside plug in the unused state, when the lid is turned in the opening direction, first, the fourth engaging portion engages with the third engaging portion in the opening direction, and the second weakened portion is broken. Thereafter, the second engaging portion engages with the first engaging portion in the opening direction, and the first weakening portion is broken.

これによると、未使用状態において、蓋を軸心方向に移動させて中栓に取付けた後、容器の内容物を注出するために蓋を中栓から取り外す場合、蓋を開方向へ回す。これにより、先ず、蓋の第４係合部が開方向において中栓の第３係合部に係合し、第２弱化部が破断して蓋本体が封印帯から離脱し、その後、蓋の第２係合部が開方向において中栓の第１係合部に係合し、第１弱化部が破断して離脱部が中栓本体から離脱し、中栓本体に注出口が形成され、容器の内容物を注出口から注出することができる。 According to this, in the unused state, after the lid is moved in the axial direction and attached to the plug, when the lid is removed from the plug in order to pour out the contents of the container, the lid is turned in the opening direction. Thereby, first, the fourth engaging portion of the lid engages with the third engaging portion of the inner plug in the opening direction, the second weakening portion breaks, and the lid main body separates from the sealing band, and thereafter the lid The second engagement portion engages with the first engagement portion of the inner plug in the opening direction, the first weakening portion is broken, the release portion is separated from the inner plug body, and the outlet port is formed in the inner plug body, The contents of the container can be dispensed from the outlet.

このように、離脱部が中栓本体から離脱するよりも先に蓋本体が封印帯から離脱するため、蓋が開方向へ回転操作されたことを確実に外部から目視で認識し得る。仮に、上記とは逆に、離脱部が中栓本体から離脱した後に蓋本体が封印帯から離脱する場合、離脱部が中栓本体から離脱しているが、蓋本体が封印帯から離脱していない状態が生じる虞がある。このような状態が生じると、蓋が既に開方向へ回転操作されているにも関わらず、蓋に対して回転操作が行われたことを確実に認識することは困難となる。 As described above, since the lid body is detached from the sealing band before the detachment portion is detached from the plug body, it is possible to visually recognize from the outside that the lid has been rotated in the opening direction. If, on the contrary to the above, the lid body is detached from the sealing band after the detachment portion is detached from the plug body, the detachment portion is detached from the plug body, but the lid body is detached from the sealing band There is a risk that a non-existence will occur. If such a state occurs, it becomes difficult to reliably recognize that the lid has been rotated in spite of the fact that the lid has already been rotated in the opening direction.

以上のように本発明によると、第３係合部と第４係合部とが閉方向において係合せず且つ開方向において係合するようなラチェット機構を構成する必要はなく、同様に、第１係合部と第２係合部とが閉方向において係合せず且つ開方向において係合するようなラチェット機構を構成する必要もない。これにより、各係合部の形状が限定されず、設計の自由度が増す。 As described above, according to the present invention, there is no need to configure a ratchet mechanism in which the third engaging portion and the fourth engaging portion do not engage in the closing direction and engage in the opening direction. It is not necessary to configure a ratchet mechanism in which the first engaging portion and the second engaging portion do not engage in the closing direction and engage in the opening direction. Thereby, the shape of each engaging portion is not limited, and the degree of freedom in design is increased.

また、離脱部が中栓本体から離脱するよりも前に蓋本体が封印帯から離脱するため、未使用状態において蓋が開方向へ回転操作されたことを確実に外部から目視で認識し得る。これにより、万一、第三者が未使用状態において蓋を開方向へ回転操作して離脱部を中栓本体から離脱させ、異物を容器内に混入させた場合、必ず蓋本体が封印帯から離脱しているため、使用者は異常を的確に察知することができる。 In addition, since the lid body is detached from the sealing band before the detachment portion is detached from the plug body, it is possible to reliably visually recognize from the outside that the lid has been rotated in the opening direction in an unused state. Thereby, in the case where a third party rotates the lid in the opening direction in an unused state to separate the disengaging part from the plug body and cause foreign matter to be mixed in the container, the lid body must always come from the sealing band Since the user has left, the user can accurately detect an abnormality.

封印帯３８は円環状のバンドである。第２弱化部３７は、周方向における複数箇所に形成された接続部位４７（ブリッジ）を残して、周方向に切断された切れ目を有している。封印帯３８は接続部位４７を介してのみスカート部４１の下端に接続されている。 An annular fitting portion 45 protruding from the inner surface of the top plate portion 40 into the holding portion 42 is provided inside the holding portion 42.
The sealing band 38 is an annular band. The second weakening portion 37 has cuts cut in the circumferential direction, with connection portions 47 (bridges) formed at a plurality of locations in the circumferential direction. The sealing band 38 is connected to the lower end of the skirt portion 41 only via the connection portion 47.

図２，図３，図５に示すように、離脱部１２の外周面には、径方向外側へ突出した複数の第１突起部４９（第１係合部の一例）が周方向Ｃにおいて所定角度αおきに形成されている。例えば、図５では、６個の第１突起部４９が６０°（所定角度αの一例）おきに形成されているが、第１突起部４９の個数は６個に限定されるものではなく、６個以外の複数個又は単数個であってもよい。 As shown in FIG. 2, FIG. 3 and FIG. 5, a plurality of first protrusions 49 (an example of the first engaging portion) projecting radially outward are predetermined in the circumferential direction C on the outer peripheral surface of the disengaging portion 12. It is formed at every angle α. For example, in FIG. 5, six first protrusions 49 are formed every 60 ° (an example of the predetermined angle α), but the number of first protrusions 49 is not limited to six, It may be plural or single other than six.

また、蓋本体３６の保持部４２の内周面には、径方向内側へ突出した複数の第２突起部５０（第２係合部の一例）が周方向Ｃにおいて所定角度αおきに形成されている。例えば、図７では、６個の第２突起部５０が６０°（所定角度αの一例）おきに形成されているが、第２突起部５０の個数は６個に限定されるものではなく、６個以外の複数個又は単数個であってもよい。 Further, on the inner peripheral surface of the holding portion 42 of the lid main body 36, a plurality of second protrusions 50 (an example of second engaging portions) protruding inward in the radial direction are formed at a predetermined angle α in the circumferential direction C. ing. For example, although six second protrusions 50 are formed every 60 ° (an example of the predetermined angle α) in FIG. 7, the number of second protrusions 50 is not limited to six, It may be plural or single other than six.

第１突起部４９と第２突起部５０とは蓋５の開方向Ｏにおいて係合可能である。
第１突起部４９は、図３に示すように、径方向外側から見て、上端（先端）が先細りの山形状であり、離脱部１２の円錐部２５の外周面と円筒部２４の外周面とにわたり形成されている。また、第２突起部５０は、図６に示すように、径方向内側から見て、下端（先端）が先細りの逆山形状である。 The first projection 49 and the second projection 50 can be engaged in the opening direction O of the lid 5.
As shown in FIG. 3, the first protrusion 49 has a mountain shape having a tapered upper end (tip) as viewed from outside in the radial direction, and the outer peripheral surface of the conical portion 25 of the separation portion 12 and the outer peripheral surface of the cylindrical portion 24 And is formed over. Further, as shown in FIG. 6, the second protrusion 50 has an inverted mountain shape whose lower end (tip) is tapered as viewed from the inner side in the radial direction.

図２〜図５に示すように、中栓本体１０の胴部１４の外周面には、径方向外側へ突出した第３突起部５２（第３係合部の一例）が周方向Ｃにおいて多数（複数）形成されている。また、図２，図６，図７に示すように、封印帯３８の内周面には、径方向内側へ突出した複数の第４突起部５３（第４係合部の一例）が周方向Ｃにおいて所定角度βおきに形成されている。例えば、図７では、１２個の第４突起部５３が３０°おきに形成されているが、第４突起部５３の個数は１２個に限定されるものではなく、１２個以外の複数個であってもよい。 As shown in FIGS. 2 to 5, a large number of third protrusions 52 (an example of third engagement portions) protruding in the radial direction on the outer peripheral surface of the body portion 14 of the inside plug body 10 in the circumferential direction C (Multiple) formed. Further, as shown in FIG. 2, FIG. 6, and FIG. 7, on the inner peripheral surface of the sealing band 38, a plurality of fourth protrusions 53 (an example of fourth engaging portions) protruding inward in the radial direction In C, they are formed at every predetermined angle β. For example, in FIG. 7, twelve fourth protrusions 53 are formed at an interval of 30 °, but the number of fourth protrusions 53 is not limited to twelve, and a plurality other than twelve may be used. It may be.

第３突起部５２と第４突起部５３とは蓋５の開方向Ｏにおいて係合可能であり、第４突起部５３はキャップ１の軸心方向Ａにおいて第３突起部５２間に挿脱自在である。
第３突起部５２（一方の突起部の一例）は、図８に示すように、径方向外側から見て、上端（先端）が先細りの山形状であり、周方向Ｃにおける片側に傾斜面５６を有している。尚、傾斜面５６は、第３突起部５２（一方の係合部の一例）間に第４突起部５３（他方の係合部の一例）を案内する案内手段の一例である。 The third projection 52 and the fourth projection 53 can be engaged in the opening direction O of the lid 5, and the fourth projection 53 can be inserted and removed between the third projections 52 in the axial direction A of the cap 1. It is.
The third protrusion 52 (an example of one protrusion) is, as shown in FIG. 8, a mountain shape in which the upper end (tip) is tapered when viewed from the radial outer side, and the inclined surface 56 is formed on one side in the circumferential direction C. have. The inclined surface 56 is an example of guiding means for guiding the fourth protrusion 53 (an example of the other engaging portion) between the third protrusions 52 (an example of the one engaging portion).

以下、上記構成における作用を説明する。
先ず、中栓４と蓋５とを個別に製作した後、離脱部１２が中栓本体１０に設けられ且つ封印帯３８が蓋本体３６に設けられている未使用状態において、蓋５を軸心方向Ａへ移動して中栓４に取り付ける。この際、図２に示すように、中栓４の内部に治具（図示省略）を挿入し、蓋５を中栓４の上方から下向き（取付方向Ｂ）に打栓する（打ち込む）。これにより、図１に示すように、保持部４２が取付方向Ｂ（すなわち打栓方向）から間隙２８（図２参照）に挿入されるとともに、頂板部４０が取付方向Ｂから離脱部１２の上端面に当接し、雌ねじ４４が雄ねじ２１を乗り越え、離脱部１２が保持部４２内に入り込んで保持され、離脱部１２の先端部が嵌め込み部４５に嵌め込まれ、図１０に示すように、蓋５の第２突起部５０が中栓４の周方向Ｃにおいて隣り同士の第１突起部４９間に挿入されるとともに、図９に示すように、蓋５の第４突起部５３が中栓４の第３突起部５２間に挿入される。これにより、第３突起部５２と第４突起部５３とが噛み合った状態で、蓋５が中栓４に取り付けられる。 Hereinafter, the operation in the above configuration will be described.
First, after the inside plug 4 and the lid 5 are separately manufactured, the lid 5 has an axial center in an unused state in which the detachment portion 12 is provided on the inside plug body 10 and the sealing band 38 is provided on the lid body 36. Move in direction A and attach to plug 4. At this time, as shown in FIG. 2, a jig (not shown) is inserted into the inside plug 4, and the lid 5 is plugged (punched) downward from above the inside plug 4 (mounting direction B). Thereby, as shown in FIG. 1, the holding portion 42 is inserted into the gap 28 (see FIG. 2) from the mounting direction B (that is, the tapping direction), and the top plate portion 40 is above the separating portion 12 from the mounting direction B. The female screw 44 passes over the male screw 21 so as to abut on the end face, the detachment portion 12 is held in the holding portion 42 and held, and the tip of the detachment portion 12 is fitted into the fitting portion 45, as shown in FIG. Is inserted between the adjacent first protrusions 49 in the circumferential direction C of the inner plug 4 and, as shown in FIG. It is inserted between the third protrusions 52. Thereby, the lid 5 is attached to the inside plug 4 in a state in which the third projection 52 and the fourth projection 53 are engaged with each other.

このとき、図１に示すように、上記のように頂板部４０が取付方向Ｂから離脱部１２の上端面に当接するため、保持部４２の間隙２８への挿入量が規制される。これにより、保持部４２が間隙２８に過剰に挿入されることはなく、保持部４２の先端が第１弱化部１１に当接して第１弱化部１１を破断させてしまうのを防止することができる。尚、雄ねじ２１が二条ねじであるのに対して雌ねじ４４が一条ねじであるため、雌ねじ４４が雄ねじ２１を乗り越えるときの抵抗が緩和される。 At this time, as shown in FIG. 1, since the top plate portion 40 abuts on the upper end surface of the separation portion 12 in the mounting direction B as described above, the insertion amount of the holding portion 42 into the gap 28 is regulated. As a result, the holding portion 42 is not excessively inserted into the gap 28, and it is possible to prevent the tip of the holding portion 42 from coming into contact with the first weakening portion 11 and breaking the first weakening portion 11. it can. In addition, since the female screw 44 is a single thread while the male screw 21 is a double thread, the resistance when the female screw 44 passes over the male screw 21 is alleviated.

また、蓋５を中栓４に打栓して取り付ける際、蓋５が中栓４に対して取付方向Ｂへ移動するのに伴って、図８に示すように、蓋５の第４突起部５３が中栓４の第３突起部５２の傾斜面５６に案内されて第３突起部５２間に確実に導入されるため、蓋５を中栓４に対し周方向Ｃにおいて位置合わせする必要はない。 In addition, when the lid 5 is plugged and attached to the inside plug 4, as the lid 5 moves in the mounting direction B with respect to the inside plug 4, as shown in FIG. Since the guide 53 is guided by the inclined surface 56 of the third projection 52 of the inner plug 4 to be reliably introduced between the third projections 52, the lid 5 needs to be aligned with the inner plug 4 in the circumferential direction C Absent.

上記のように未使用状態において蓋５を中栓４に打栓して取付けた後、治具を中栓４の内部から取り外し、図１に示すように、容器２の口部３を嵌入部２０に嵌め込んで、中栓４を容器２に取付ける。 After plugging the lid 5 to the inside plug 4 in an unused state as described above and attaching it, the jig is removed from the inside of the inside plug 4 and the opening 3 of the container 2 is fitted as shown in FIG. Fit in 20 and attach the plug 4 to the container 2.

その後、容器２の内容物を注出するために蓋５を中栓４から取り外す場合、蓋５を開方向Ｏへ回す。これにより、先ず、図９に示すように、蓋５の第４突起部５３が開方向Ｏにおいて中栓４の第３突起部５２に係合し、封印帯３８が蓋本体３６の開方向Ｏへの回動に追従することができず、第２弱化部３７の接続部位４７が破断して、蓋本体３６が封印帯３８から離脱する。その直後、図１０の仮想線で示すように、蓋５の第２突起部５０が開方向Ｏにおいて中栓４の第１突起部４９に係合し、図１１に示すように、第１弱化部１１が破断して離脱部１２が中栓本体１０から離脱し、中栓本体１０に注出口２２が形成され、容器２の内容物を注出口２２から注出することができる。 Thereafter, when the lid 5 is removed from the inside plug 4 in order to pour out the contents of the container 2, the lid 5 is turned in the opening direction O. Thereby, first, as shown in FIG. 9, the fourth projection 53 of the lid 5 engages with the third projection 52 of the inside plug 4 in the opening direction O, and the sealing belt 38 is in the opening direction O of the lid main body 36. The connection portion 47 of the second weakening portion 37 is broken, and the lid body 36 is separated from the sealing band 38. Immediately thereafter, the second projection 50 of the lid 5 engages with the first projection 49 of the inner plug 4 in the opening direction O as shown by the phantom line in FIG. 10, and as shown in FIG. The part 11 is broken so that the separation part 12 is separated from the inside plug body 10, and the spout 22 is formed in the inside plug body 10, and the contents of the container 2 can be dispensed from the spout 22.

尚、図８（ｂ）および図９に示すように、蓋５の第４突起部５３が中栓４の第３突起部５２間に挿入されて、第３突起部５２と第４突起部５３とが噛み合った状態であるため、図１１に示すように、蓋本体３６から分断されて中栓本体１０側に残留した封印帯３８が中栓本体１０から取外方向Ｄへ脱抜されるのを防止することができる。 As shown in FIGS. 8B and 9, the fourth protrusion 53 of the lid 5 is inserted between the third protrusions 52 of the inner plug 4, and the third protrusions 52 and the fourth protrusions 53 are inserted. And the sealing strip 38 separated from the lid body 36 and remaining on the inside plug body 10 side is pulled out from the inside plug body 10 in the removal direction D as shown in FIG. Can be prevented.

このように、離脱部１２が中栓本体１０から離脱するよりも先に蓋本体３６が封印帯３８から離脱するため、蓋５が開方向Ｏへ回転操作されたことを確実に外部から目視で認識し得る。これにより、万一、第三者が未使用状態において蓋５を開方向Ｏへ回転操作して離脱部１２を中栓本体１０から僅かに離脱させ、異物を外部から容器２内に混入させた場合、必ず蓋本体３６が封印帯３８から離脱しているため、使用者は異常を的確に察知することができる。 As described above, since the lid body 36 is detached from the sealing band 38 before the detachment portion 12 is detached from the inner plug body 10, it is surely confirmed from the outside that the lid 5 has been rotated in the opening direction O It can be recognized. Thus, in the case where a third party rotates the lid 5 in the opening direction O in an unused state, the detachment portion 12 is slightly detached from the inside plug main body 10 and foreign matter is mixed into the container 2 from the outside. In this case, since the lid main body 36 is always detached from the sealing band 38, the user can accurately detect an abnormality.

仮に、上記とは逆に、離脱部１２が中栓本体１０から離脱した後に蓋本体３６が封印帯３８から離脱する場合、離脱部１２が中栓本体１０から離脱しているが、蓋本体３６が封印帯３８から離脱していない状態が生じる虞がある。このような状態が生じると、第三者により蓋５が既に開方向Ｏへ回転操作されているにも関わらず、蓋５に対して回転操作が行われたことを確実に認識することは困難となるため、使用者は異常を察知することが困難となる。 On the contrary, when the lid body 36 is detached from the sealing band 38 after the detachment portion 12 is detached from the inner plug body 10, the detachment portion 12 is detached from the inner plug body 10, contrary to the above. There is a possibility that a state where it does not separate from the sealing band 38 may occur. If such a state occurs, it is difficult to reliably recognize that the rotation operation has been performed on the lid 5 despite the fact that the lid 5 has already been rotated in the opening direction O by a third party This makes it difficult for the user to detect an abnormality.

また、離脱部１２は保持部４２内に入り込んで保持されているため、蓋５を開方向Ｏへ回転して中栓４から取り外した際、図１１に示すように、離脱部１２は蓋５の内側から脱落せずに蓋５の内側に留まる。このように、蓋５に円筒状の保持部４２を備えるだけのシンプルな構成で、離脱部１２を蓋５の内側に保持することができる。 Further, since the disengaging portion 12 is held in the holding portion 42, when the lid 5 is rotated in the opening direction O and removed from the plug 4, as shown in FIG. Stay inside the lid 5 without falling off from the inside of the Thus, the detachment portion 12 can be held on the inside of the lid 5 with a simple configuration in which the lid 5 is provided with the cylindrical holding portion 42 as well.

また、上記のように、未使用状態において、蓋５を閉方向Ｓへ回して中栓４に取り付けるのではなく、図２に示すように、蓋５を軸心方向Ａから中栓４に打栓して（打ち込んで）取付けることができるため、第３突起部５２と第４突起部５３とが蓋５の閉方向Ｓにおいて係合せず且つ開方向Ｏにおいて係合するようなラチェット機構を構成する必要はない。同様に、第１突起部４９と第２突起部５０とが蓋５の閉方向Ｓにおいて係合せず且つ開方向Ｏにおいて係合するようなラチェット機構を構成する必要もない。これにより、第１〜第４突起部４９，５０，５２，５３の形状が限定されず、設計の自由度が増す。 Further, as described above, in the unused state, instead of turning the lid 5 in the closing direction S and attaching it to the inside plug 4, as shown in FIG. Since it can be plugged and installed, the ratchet mechanism is configured such that the third projection 52 and the fourth projection 53 do not engage in the closing direction S of the lid 5 and engage in the opening direction O. do not have to. Similarly, there is no need to configure a ratchet mechanism in which the first projection 49 and the second projection 50 do not engage in the closing direction S of the lid 5 and engage in the opening direction O. Thus, the shapes of the first to fourth protrusions 49, 50, 52, 53 are not limited, and the degree of freedom in design is increased.

上記第１の実施の形態では、第４突起部５３の個数を第３突起部５２の個数よりも少なくしているが、同数であってもよい。また、第３突起部５２の個数を第４突起部５３の個数より少なくしてもよい。 In the first embodiment, the number of fourth protrusions 53 is smaller than the number of third protrusions 52, but the number may be the same. In addition, the number of third protrusions 52 may be smaller than the number of fourth protrusions 53.

上記第１の実施の形態では、図８に示すように、傾斜面５６を、第３突起部５２に形成したが、第４突起部５３に形成してもよく、或いは両突起部５２，５３にそれぞれ形成してもよい。 In the first embodiment, as shown in FIG. 8, the inclined surface 56 is formed on the third projection 52, but may be formed on the fourth projection 53 or both projections 52 and 53. It may be formed respectively.

A plurality of fourth claws 71 (an example of a fourth engagement portion) protruding in the mounting direction B of the lid 5 and the other retaining projections 72 are formed in the sealing belt 66 in the circumferential direction C. There is.

第３爪部６８と第４爪部７１とは蓋５の開方向Ｏにおいて係合可能であり、第４爪部７１はキャップ１の軸心方向Ａにおいて第３爪部６８間に挿脱自在である。
第３爪部６８（一方の突起部の一例）は、図１２，図１４に示すように、径方向外側から見て、蓋５の取外方向Ｄにおける端部が先細りの三角波形状であり、周方向Ｃにおける片側に傾斜面７４を有している。 The third claw portion 68 and the fourth claw portion 71 can be engaged in the opening direction O of the lid 5, and the fourth claw portion 71 can be inserted and removed between the third claw portions 68 in the axial direction A of the cap 1 It is.
As shown in FIGS. 12 and 14, the third claw portion 68 (an example of one protrusion portion) has a triangular wave shape whose end in the removal direction D of the lid 5 has a tapered shape as viewed from the radial outer side, An inclined surface 74 is provided on one side in the circumferential direction C.

第４爪部７１（他方の突起部の一例）は、図１５，図１６に示すように、径方向外側から見て、蓋５の取付方向Ｂにおける端部が先細りの逆三角波形状であり、周方向Ｃにおける片側に傾斜面７５を有している。尚、両傾斜面７４，７５は第３爪部６８（一方の係合部の一例）間に第４爪部７１（他方の係合部の一例）を案内する案内手段の一例であり、図１８に示すように、蓋５を中栓４に取り付けた状態では、両傾斜面７４，７５同士が軸心方向Ａにおいて当接している。 The fourth claw portion 71 (an example of the other protrusion portion) has an inverse triangular wave shape in which the end in the mounting direction B of the lid 5 has a tapered shape as viewed from outside in the radial direction, as shown in FIGS. An inclined surface 75 is provided on one side in the circumferential direction C. The two inclined surfaces 74 and 75 are an example of guiding means for guiding the fourth claw portion 71 (an example of the other engagement portion) between the third claw portions 68 (an example of the one engagement portion). As shown in 18, in the state where the lid 5 is attached to the inside plug 4, the two inclined surfaces 74, 75 abut each other in the axial direction A.

図１２，図１４に示すように、一方の抜止用突部６９は周方向Ｃにおいて隣接している第３爪部６８間に形成され、図１６，図１７に示すように、他方の抜止用突部７２は第４爪部７１の内側に形成されている。図１８に示すように、蓋５を中栓４に取り付けた状態では、他方の抜止用突部７２は取外方向Ｄにおいて一方の抜止用突部６９に係合する。 As shown in FIGS. 12 and 14, one retaining projection 69 is formed between the third claws 68 adjacent in the circumferential direction C, and as shown in FIGS. The protrusion 72 is formed inside the fourth claw portion 71. As shown in FIG. 18, when the lid 5 is attached to the inside plug 4, the other retaining projection 72 engages with one retaining projection 69 in the removal direction D.

以下、上記構成における作用を説明する。
中栓４と蓋５とを個別に製作した後、図１４に示すように、離脱部１２が中栓本体１０に設けられ且つ封印帯６６が蓋本体３６に設けられている未使用状態において、蓋５を取付方向Ｂから中栓４に打栓する。これにより、図１８に示すように、蓋５の第２突起部５０が中栓４の周方向Ｃにおいて隣り同士の第１突起部４９間に挿入されるとともに、他方の抜止用突部７２が一方の抜止用突部６９を取付方向Ｂに乗り越えて、蓋５の第４爪部７１が中栓４の第３爪部６８間に挿入される。これにより、第４爪部７１が第３爪部６８に噛み合って、蓋５が中栓４に取り付けられる。 Hereinafter, the operation in the above configuration will be described.
After the inner plug 4 and the lid 5 are separately manufactured, as shown in FIG. 14, in the unused state in which the detachment portion 12 is provided on the inner plug body 10 and the sealing band 66 is provided on the lid main body 36, The lid 5 is plugged from the mounting direction B to the inside plug 4. Thereby, as shown in FIG. 18, the second projection 50 of the lid 5 is inserted between the adjacent first projections 49 in the circumferential direction C of the inner plug 4, and the other projection 72 is The fourth claw portion 71 of the lid 5 is inserted between the third claw portions 68 of the inner plug 4 by getting over one of the retaining projections 69 in the mounting direction B. As a result, the fourth claw portion 71 meshes with the third claw portion 68, and the lid 5 is attached to the inside plug 4.

中栓４を容器２に取付けた後、容器２の内容物を注出するために蓋５を中栓４から取り外す場合、蓋５を開方向Ｏへ回す。これにより、先ず、蓋５の第４爪部７１が開方向Ｏにおいて中栓４の第３爪部６８に係合し、封印帯６６が蓋本体３６の開方向Ｏへの回動に追従することができず、第２弱化部３７の接続部位４７が破断して、蓋本体３６が封印帯６６から離脱する。その直後、蓋５の第２突起部５０が開方向Ｏにおいて中栓４の第１突起部４９に係合し、第１弱化部１１が破断して離脱部１２が中栓本体１０から離脱し、図１９に示すように、中栓本体１０に注出口２２が形成され、容器２の内容物を注出口２２から注出することができる。 After attaching the inside plug 4 to the container 2, when removing the lid 5 from the inside plug 4 in order to pour out the contents of the container 2, the lid 5 is turned in the opening direction O. Thereby, first, the fourth claw portion 71 of the lid 5 engages with the third claw portion 68 of the inner plug 4 in the opening direction O, and the sealing band 66 follows the rotation of the lid main body 36 in the opening direction O If it can not be done, the connection part 47 of the second weakening part 37 is broken, and the lid body 36 is separated from the sealing band 66. Immediately after that, the second projection 50 of the lid 5 engages with the first projection 49 of the inner plug 4 in the opening direction O, and the first weakening portion 11 breaks and the disengaging portion 12 is released from the inner plug body 10 As shown in FIG. 19, a spout 22 is formed in the inside plug body 10, and the contents of the container 2 can be spouted from the spout 22.

また、図１９に示すように、封印帯６６の他方の抜止用突部７２が取外方向Ｄにおいて中栓本体１０の一方の抜止用突部６９に係合するため、蓋本体３６から分断されて中栓本体１０側に残留した封印帯６６が中栓本体１０から取外方向Ｄへ脱抜されるのを防止することができる。 In addition, as shown in FIG. 19, the other protrusion 72 of the sealing band 66 is engaged with one protrusion 69 of the inside plug body 10 in the removal direction D, so that it is separated from the lid main body 36. It is possible to prevent the sealing band 66 remaining on the inner plug body 10 side from being removed from the inner plug body 10 in the removal direction D.

また、上記のように、未使用状態において、蓋５を閉方向Ｓへ回して中栓４に取り付けるのではなく、図１４に示すように、蓋５を軸心方向Ａから中栓４に打栓して（打ち込んで）取付けることができるため、第３爪部６８と第４爪部７１とが閉方向Ｓにおいて係合せず且つ開方向Ｏにおいて係合するようなラチェット機構を構成する必要はない。これにより、第３および第４爪部６８，７１の形状が限定されず、設計の自由度が増す。 Further, as described above, in the unused state, instead of turning the lid 5 in the closing direction S and attaching it to the inside plug 4, as shown in FIG. It is necessary to construct a ratchet mechanism that allows the third claw portion 68 and the fourth claw portion 71 not to engage in the closing direction S and to engage in the opening direction O, since they can be plugged and driven. Absent. Thus, the shapes of the third and fourth claws 68 and 71 are not limited, and the degree of freedom in design is increased.

尚、上記のように蓋５を中栓４に打栓して取り付ける際には、第４爪部７１が第３爪部６８に正確に噛み合うように、中栓４に対する蓋５の位置を周方向Ｃにおいて決めておく必要がある。但し、第４爪部７１の位置が第３爪部６８に対して周方向Ｃに若干ずれても、第４爪部７１の傾斜面７５が第３爪部６８の傾斜面７４に当接して開方向Ｏへ案内されることで、中栓４に対する蓋５の位置が修正され、第４爪部７１が第３爪部６８に正確に噛み合う。尚、このような位置修正機能は、両傾斜面７４，７５の傾斜角度が急なほど、顕著に発揮される。 In addition, when the lid 5 is plugged and attached to the inside plug 4 as described above, the position of the lid 5 with respect to the inside plug 4 is circumferentially set so that the fourth claw portion 71 engages with the third claw portion 68 correctly. It is necessary to decide in the direction C. However, even if the position of the fourth claw portion 71 is slightly shifted in the circumferential direction C with respect to the third claw portion 68, the inclined surface 75 of the fourth claw portion 71 abuts on the inclined surface 74 of the third claw portion 68. By being guided in the opening direction O, the position of the lid 5 with respect to the inside plug 4 is corrected, and the fourth claw 71 engages with the third claw 68 exactly. In addition, such a position correction function is exhibited notably, so that the inclination angle of both the inclined surfaces 74 and 75 is steep.

（第３の実施の形態）
以下に説明する第３の実施の形態のキャップ１は、先に説明した第１の実施の形態のキャップ１の変形例であり、第１の実施の形態のキャップ１と同じ構成については同一の符号を付して、その詳細な説明を省略する。 Third Embodiment

図２０〜図２２に示すように、未使用状態において蓋５を中栓４に取り付ける際、蓋５と中栓４との周方向Ｃにおける相対的な位置を決める複数の位置決め部８１，８２（位置決め手段の一例）が蓋５と中栓４とにそれぞれ設けられている。このうち、図２０，図２１に示すように、中栓側位置決め部８１は、中栓４の離脱部１２の内側に設けられた凸状のリブであり、周方向Ｃにおいて所定角度（例えば図２１では６０°）おきに複数形成されている。 As shown in FIGS. 20 to 22, when attaching the lid 5 to the inside plug 4 in an unused state, a plurality of positioning portions 81, 82 (relative position in the circumferential direction C between the lid 5 and the inside plug 4) An example of positioning means is provided on the lid 5 and the inside plug 4 respectively. Among these, as shown in FIG. 20 and FIG. 21, the inside plug side positioning part 81 is a convex rib provided on the inside of the disengaging part 12 of the inside plug 4 and has a predetermined angle in the circumferential direction C (for example, 21 are formed at intervals of 60 °.

また、図２０，図２２に示すように、蓋側位置決め部８２は、蓋５のスカート部４１の外周面に設けられた山形状の部材であり、周方向Ｃにおいて所定角度（例えば図２２では６０°）おきに複数形成されている。尚、蓋側位置決め部８２はスカート部４１の外周面に形成されたローレットを異なった形状に加工したものである。 In addition, as shown in FIGS. 20 and 22, the lid-side positioning portion 82 is a mountain-shaped member provided on the outer peripheral surface of the skirt portion 41 of the lid 5, and has a predetermined angle in the circumferential direction C (for example, in FIG. Multiple) are formed every 60 °). The lid-side positioning portion 82 is formed by processing the knurl formed on the outer peripheral surface of the skirt portion 41 into a different shape.

また、未使用状態において、蓋５を軸心方向Ａへ移動して中栓４に取り付ける際、図２３に示すように、中栓４を中栓用治具８４に嵌め、蓋５を蓋用治具８５に嵌め、蓋５を中栓４の上方から下向き（取付方向Ｂ）に打栓する。 In addition, when the lid 5 is moved in the axial direction A and attached to the inner plug 4 in the unused state, as shown in FIG. 23, the inner plug 4 is fitted to the inner plug jig 84 and the lid 5 is used for the lid The jig 5 is fitted, and the lid 5 is plugged from above the plug 4 downward (in the mounting direction B).

中栓用治具８４は、上部に、中栓４の離脱部１２の内側に挿入される円形の挿入端部８６を有している。図２３〜図２５に示すように、挿入端部８６の外周面には、複数の治具側中栓用位置決め溝８７（治具側中栓用位置決め手段の一例）が周方向Ｃにおいて所定角度（例えば図２４では６０°）おきに形成されている。 The plugging jig 84 has a circular insertion end 86 at the top, which is inserted into the inside of the release portion 12 of the plug 4. As shown in FIGS. 23 to 25, on the outer peripheral surface of the insertion end portion 86, a plurality of positioning grooves 87 for plugging in the jig (one example of positioning means for plugging in the jig) have a predetermined angle in the circumferential direction C For example, they are formed at every 60 ° in FIG.

図２３，図２６，図２７に示すように、蓋用治具８５は、下方が開放された円形の嵌合凹部８８を有している。嵌合凹部８８の内周面には、谷形状の複数の治具側蓋用位置決め溝８９（治具側蓋用位置決め手段の一例）が周方向Ｃにおいて所定角度（例えば図２６では６０°）おきに形成されている。 As shown in FIG. 23, FIG. 26, and FIG. 27, the lid jig 85 has a circular fitting recess 88 whose lower side is opened. On the inner peripheral surface of the fitting recess 88, a plurality of valley-shaped positioning grooves 89 for the lid (an example of positioning means for the lid on the jig) have a predetermined angle in the circumferential direction C (for example, 60 ° in FIG. 26) It is formed every moment.

蓋用治具８５は、蓋５を中栓４にセットするキャップセット装置（図示省略）に保持されて、上方から中栓用治具８４に対向しており、中栓用治具８４に対して上下方向に移動自在に構成されている。 The lid jig 85 is held by a cap setting device (not shown) for setting the lid 5 to the inner plug 4 and is opposed to the inner plug jig 84 from the upper side. Is vertically movable.

以下、上記構成における作用を説明する。
未使用状態において、蓋５を中栓４に取り付ける際、図２３に示すように中栓４を中栓用治具８４に嵌め、蓋５を蓋用治具８５に嵌める。このとき、図２４，図２５に示すように、中栓４の中栓側位置決め部８１を中栓用治具８４の治具側中栓用位置決め溝８７に挿入することにより、中栓４が中栓用治具８４に対して周方向Ｃに位置決めされる。また、図２６，図２７に示すように、蓋５の蓋側位置決め部８２を蓋用治具８５の治具側蓋用位置決め溝８９に挿入することにより、蓋５が蓋用治具８５に対して周方向Ｃに位置決めされる。 Hereinafter, the operation in the above configuration will be described.
When the lid 5 is attached to the inside plug 4 in the unused state, as shown in FIG. 23, the inside plug 4 is fitted to the inside plug jig 84, and the lid 5 is fitted to the lid jig 85. At this time, as shown in FIGS. 24 and 25, the inner plug 4 is inserted by inserting the inner plug side positioning portion 81 of the inner plug 4 into the jig side inner plug positioning groove 87 of the inner plug jig 84. It is positioned in the circumferential direction C with respect to the inside plug jig 84. Further, as shown in FIG. 26 and FIG. 27, the lid 5 is inserted into the lid jig 85 by inserting the lid side positioning portion 82 of the lid 5 into the jig side lid positioning groove 89 of the lid jig 85. It is positioned in the circumferential direction C.

これにより、蓋５と中栓４とが周方向Ｃにおいて相対的に位置決めされ、図２３の矢印に示すように、この状態で、キャップセット装置を作動させ、蓋用治具８５と共に蓋５を下降させ上方から中栓４に打栓することによって、図２９に示すように、蓋５の第２突起部５０が中栓４の周方向Ｃにおいて隣り同士の第１突起部４９間に確実に挿入されるとともに、図２８に示すように、蓋５の第４突起部５３が中栓４の第３突起部５２間に確実に挿入される。尚、このとき、図２９の実線で示すように、第２突起部５０は第１突起部４９の開方向Ｏ側に隣接する位置に確実に定められ、第３突起部５２と第４突起部５３とが噛み合った状態で、図２０に示すように、蓋５が中栓４に取り付けられる。 Thereby, the lid 5 and the inner plug 4 are positioned relative to each other in the circumferential direction C, and the cap setting device is operated in this state as shown by the arrow in FIG. By lowering and plugging the plug 4 from above, as shown in FIG. 29, the second protrusions 50 of the lid 5 are reliably between the adjacent first protrusions 49 in the circumferential direction C of the plug 4. While being inserted, as shown in FIG. 28, the fourth projection 53 of the lid 5 is securely inserted between the third projections 52 of the inner plug 4. At this time, as shown by the solid line in FIG. 29, the second projection 50 is reliably determined at a position adjacent to the opening direction O of the first projection 49, and the third projection 52 and the fourth projection In a state in which 53 engages, the lid 5 is attached to the inside plug 4 as shown in FIG.

このようにして蓋５を中栓４に取付けた後、蓋用治具８５を上昇させ、蓋５を蓋用治具８５から離脱し、中栓４を中栓用治具８４から取り外し、中栓４を容器２に取付ける。
その後、容器２の内容物を注出するために蓋５を中栓４から取り外す場合、蓋５を開方向Ｏへ回す。これにより、先ず、図２８に示すように、蓋５の第４突起部５３が開方向Ｏにおいて中栓４の第３突起部５２に係合し、封印帯３８が蓋本体３６の開方向Ｏへの回動に追従することができず、第２弱化部３７の接続部位４７が破断して、蓋本体３６が封印帯３８から離脱する。その直後、図２９の仮想線で示すように、蓋５の第２突起部５０が開方向Ｏにおいて中栓４の第１突起部４９に係合し、第１弱化部１１が破断して離脱部１２が中栓本体１０から離脱し、中栓本体１０に注出口２２が形成され、容器２の内容物を注出口２２から注出することができる。 After the lid 5 is attached to the inside plug 4 in this manner, the lid jig 85 is raised, the lid 5 is detached from the lid jig 85, and the inside plug 4 is removed from the inside plug jig 84. Attach the stopper 4 to the container 2.
Thereafter, when the lid 5 is removed from the inside plug 4 in order to pour out the contents of the container 2, the lid 5 is turned in the opening direction O. Thereby, first, as shown in FIG. 28, the fourth projection 53 of the lid 5 engages with the third projection 52 of the inside plug 4 in the opening direction O, and the sealing belt 38 is in the opening direction O of the lid main body 36. The connection portion 47 of the second weakening portion 37 is broken, and the lid body 36 is separated from the sealing band 38. Immediately after that, as shown by the phantom line in FIG. 29, the second projection 50 of the lid 5 engages with the first projection 49 of the inner plug 4 in the opening direction O, and the first weakening portion 11 is broken and separated. The portion 12 is separated from the inside plug body 10, and the inside outlet body 10 is formed with the outlet 22 so that the contents of the container 2 can be poured out from the outlet 22.

このように、離脱部１２が中栓本体１０から離脱するよりも先に蓋本体３６が封印帯３８から離脱するため、蓋５が開方向Ｏへ回転操作されたことを確実に外部から目視で認識し得る。これにより、万一、第三者が未使用状態のキャップ１の蓋５を開方向Ｏへ回転操作して離脱部１２を中栓本体１０から僅かに離脱させ、異物を外部から容器２内に混入させた場合、必ず蓋本体３６が封印帯３８から離脱しているため、使用者は異常を的確に察知することができる。 As described above, since the lid body 36 is detached from the sealing band 38 before the detachment portion 12 is detached from the inner plug body 10, it is surely confirmed from the outside that the lid 5 has been rotated in the opening direction O It can be recognized. As a result, a third party rotates the lid 5 of the unused cap 1 in the opening direction O to slightly detach the disengaging portion 12 from the inside plug main body 10, and foreign substances are introduced into the container 2 from the outside. In the case of mixing, since the lid body 36 is always detached from the sealing band 38, the user can accurately detect an abnormality.

上記第３の実施の形態では、図２４，図２６に示すように、中栓側位置決め部８１と蓋側位置決め部８２と治具側中栓用位置決め溝８７と治具側蓋用位置決め溝８９とをそれぞれ６カ所ずつ設けているが、６カ所以外の複数箇所又は１カ所に設けてもよい。 In the third embodiment, as shown in FIGS. 24 and 26, the inside plug side positioning portion 81, the lid side positioning portion 82, the jig side inside plug positioning groove 87, and the jig side lid positioning groove 89. Are provided at six places each, but may be provided at a plurality of places other than six places or one place.
