しかしながら、こうした従来のヒンジキャップは、貫通孔での目詰まりを防止できるものの、蓋体を閉じた状態での気密性の確保は、蓋体とベースの上部外表面とが面一状態となるようにすることで行なうのみであり、必ずしも気密性を確保できるものではなかった。 However, such a conventional hinge cap can prevent clogging in the through hole, but ensuring the airtightness when the lid is closed is such that the lid and the upper outer surface of the base are flush with each other. However, it was not always possible to ensure airtightness.

本発明の解決すべき課題は、ベースの貫通孔での目詰まりを防止しつつ、蓋体を閉じた状態での気密性を確保できるヒンジキャップを提供することにある。 The problem to be solved by the present invention is to provide a hinge cap capable of ensuring airtightness in a state in which a lid is closed while preventing clogging at a through hole of a base.

本発明であるヒンジキャップは、容器の内部に通じる貫通孔を有し当該容器の口部に装着されるベースと、このベースの貫通孔に挿入可能な突起を有しヒンジを介して揺動可能に繋がる蓋体とを備えるヒンジキャップであって、前記ベースの外表面に、前記貫通孔を取り囲むように配置され、当該蓋体の閉じ状態において、前記蓋体に接触して前記貫通孔の周りを密封する環状の弾性部材を備えることを特徴とするものである。 The hinge cap according to the present invention has a through-hole that leads to the inside of the container, a base that is attached to the mouth of the container, and a protrusion that can be inserted into the through-hole of the base, and can swing through the hinge. A hinge cap provided on the outer surface of the base so as to surround the through-hole and in contact with the lid when the lid is in a closed state. An annular elastic member is provided for sealing.

上記発明において、前記弾性部材は、蓋体の閉じ状態において、当該蓋体の裏面に接触する凸形状をしてなるものとすることができる。 In the above invention, the elastic member may have a convex shape that comes into contact with the back surface of the lid in the closed state of the lid.

また、上記発明は、前記弾性部材の内縁全周に、当該内縁の内側の前記貫通孔を除いた全体を満たすように繋がり、蓋体の閉じ状態において、当該蓋体との相互間に隙間を形成する補助弾性部を設けてもよく、また、上記発明において、前記弾性部材は、その内縁を前記貫通孔の口径に対応させてなり、当該弾性部材の外縁全周に、当該外縁の外側全体をシート状に繋ぎ、前記蓋体の閉じ状態において、当該蓋体との相互間に隙間を形成する補助弾性部を設けてもよい。 In the above invention, the entire circumference of the inner edge of the elastic member is connected so as to fill the entire area excluding the through hole inside the inner edge, and in the closed state of the lid, a gap is formed between the lid and the lid. An auxiliary elastic portion to be formed may be provided, and in the above invention, the elastic member has an inner edge corresponding to the diameter of the through hole, and the entire outer edge of the outer edge of the elastic member is entirely outside. May be provided in the form of a sheet, and in the closed state of the lid, an auxiliary elastic portion may be provided that forms a gap between the lid and the lid.

更に、上記発明は、前記環状部材に、前記蓋体に折り曲げ可能に繋がり当該蓋体を開き状態に付勢する延長弾性部を設けてなることが好ましい。 Further, in the above invention, it is preferable that the annular member is provided with an extended elastic portion that is foldably connected to the lid body and biases the lid body in an open state.

また、本発明に係る、ヒンジキャップは、容器の内部に通じる貫通孔が前方に形成された天壁部を有し当該天壁部から容器の口部に装着される装着部が垂下するベースと、このベースの壁部の背面を窪ませて棚面を有する窪みを形成して当該窪みの棚面に傾動可能に一体に立設した押圧板と、ベースの貫通孔に挿入可能な突起を有し前記押圧板の上端部にヒンジを介して揺動可能に繋がる蓋体とを備えるヒンジキャップであって、前記押圧板の上端部のうち、その裏面側を一部切り欠いて押圧板の幅方向に延在する段部を形成する一方、当該押圧板の幅方向に沿って延在すると共に前記段部に一体に成形される横架弾性部材を設け、当該横架弾性部材の端部をそれぞれ、前記ベースに形成された窪みの側縁に固定保持して当該窪みに向けての前記押圧板の押し込みに抗する付勢力を得るものとすることができる。 Further, the hinge cap according to the present invention has a top wall part in which a through hole leading to the inside of the container is formed forward, and a base from which a mounting part attached to the mouth part of the container hangs from the top wall part. The bottom of the base wall is recessed to form a recess having a shelf surface, and a pressing plate that is integrally provided to be tiltable on the shelf surface of the recess, and a protrusion that can be inserted into the through-hole of the base. And a lid that is swingably connected to the upper end portion of the pressing plate via a hinge, wherein the back surface of the upper end portion of the pressing plate is partially cut away to reduce the width of the pressing plate. A horizontal elastic member that extends along the width direction of the pressing plate and is integrally formed with the step is formed, and an end portion of the horizontal elastic member is formed. Each is fixedly held on the side edge of the depression formed in the base and directed toward the depression. It can be made to obtain a biasing force against the pushing of the serial pressing plate.

なお、本発明において、前記貫通孔は、少なくとも１つであればよい。また、「環状」とは円形に閉じられたものだけでなく、三角や矩形等の多角形に閉じられたものも含む。加えて、上記弾性部材と各弾性部とは、例えば、インサート成形により一体成形できる。更に、弾性部材に用いる材質は、エラストマやこれに類する弾性を有する材質等が挙げられる。 In the present invention, the number of through holes may be at least one. In addition, “annular” includes not only a circular shape but also a closed shape such as a triangle or a rectangle. In addition, the elastic member and each elastic portion can be integrally formed by insert molding, for example. Further, examples of the material used for the elastic member include an elastomer and a material having elasticity similar to the elastomer.

本発明の如く、蓋体の裏面に、当該蓋体の閉じ状態にて、ベースの貫通孔に挿入される突起を有し、更に、ベースの外表面に、前記貫通孔を取り囲むように配置され、当該蓋体の閉じ状態において、前記蓋体に接触して前記貫通孔の周りを密封する環状の弾性部材を設ければ、前記突起の挿入によりベースの貫通孔での目詰まりを防止し、更に、前記貫通孔を取り囲んだ環状の弾性部材が蓋体と接触することにより当該蓋体を閉じた状態での気密性も確保することもできる。 As in the present invention, the back surface of the lid body has a protrusion inserted into the through hole of the base in the closed state of the lid body, and is further disposed on the outer surface of the base so as to surround the through hole. In the closed state of the lid body, if an annular elastic member that contacts the lid body and seals around the through hole is provided, clogging in the through hole of the base is prevented by inserting the protrusion, Furthermore, when the annular elastic member surrounding the through hole comes into contact with the lid, airtightness in a state where the lid is closed can be ensured.

また、上記発明において、前記弾性部材が、蓋体の閉じ状態において、当該蓋体の裏面に接触する凸形状をしてなるものであれば、蓋体を閉じた状態での接触は、凸形状をしてなる環状の弾性部材の頂部に集中するため、蓋体を閉じた状態での気密性の確保を更に確実なものとすることができる。 Moreover, in the said invention, if the said elastic member has a convex shape which contacts the back surface of the said cover body in the closed state of a cover body, the contact in the state which closed the cover body is convex shape. Since it concentrates on the top part of the cyclic | annular elastic member which carries out, securing of airtightness in the state which closed the cover body can be made still more reliable.

更に、上記発明において、前記弾性部材に、前記蓋体に折り曲げ可能に繋がり前記蓋体を開き状態に付勢する弾性延長部を設ければ、上述した効果を奏する操作性に優れたヒンジキャップを提供することができる。 Furthermore, in the above invention, if the elastic member is provided with an elastic extension portion that is foldably connected to the lid body and biases the lid body in an open state, a hinge cap excellent in operability that exhibits the above-described effects can be obtained. Can be provided.

FIG. 2 (a) and 2 (b) are a cross-sectional view taken along line XX in FIG. 1 (a) and a cross-sectional view showing the closed state of the lid body 13 along the line XX in FIG. 1 (a). . Further, FIG. 3 is an enlarged cross-sectional view of FIG.

符号11は、図１(a)に示すように、図示せぬ容器の内部に通じる５つの貫通孔11aを有するベースである。ベース11は、図１(b)に示すように、その内側下部に容器の口部に螺着される装着部11bを有し、その外表面には、貫通孔11aの前方から背面に亘って延在する窪みＣ(C₁,C₂,C₃)が形成されている。窪みＣのうち、ベース11の背面を窪ませた窪みC₃は、図２(a)に示すように、装着部11bとの間に平坦な棚部11cを形成する。 Reference numeral 11 denotes a base having five through holes 11a communicating with the inside of a container (not shown) as shown in FIG. As shown in FIG. 1 (b), the base 11 has a mounting portion 11b that is screwed into the mouth portion of the container at the inner lower portion thereof, and the outer surface thereof extends from the front to the back of the through hole 11a. An extending recess C (C ₁ , C ₂ , C ₃ ) is formed. Of recesses C, depression C ₃ is recessed to the rear of the base 11, as shown in FIG. 2 (a), to form a flat ledge 11c between the mounting portion 11b.

符号12は、図１(b)に示すように、窪みC₃を形成する２つの側縁ｅ₁,ｅ₂のうち、窪みC₃の狭幅部分を形成する側縁ｅ₂との間にスリットＳを形成し、棚面11cから一体に立設された平板状の押圧板である。押圧板12には更に、棚面11cより高い位置に、横方向に沿って伸びる折り曲げ可能な薄肉部12tが形成されている。 Reference numeral 12, as shown in FIG. 1 (b), of the recess C ₃ 2 two side edges forming the e _1, e _2, between the side edge e ₂ to form a narrow portion of the recess C ₃ It is a flat pressing plate that forms a slit S and is erected integrally from the shelf surface 11c. The pressing plate 12 is further formed with a foldable thin portion 12t extending along the lateral direction at a position higher than the shelf surface 11c.

これにより、押圧板12は、薄肉部12tを起点に、図２(a)の矢印D₁に示すように、ベース11の前面側及び背面側に揺動することができる。押圧板12は、使用者が実際に押し込む側に、使用者の指先が当たる突条12aを有する。 Thus, the pressing plate 12, starting from the thin portion 12t, as shown by an arrow D ₁ of the FIG. 2 (a), the can be swung to the front side and rear side of the base 11. The pressing plate 12 has a ridge 12a on which the user's fingertip hits on the side where the user actually pushes.

符号13は、図１(a)に示すように、ベース11に形成した窪みＣに略等しい幅を有し、押圧板12の上端部12eにそれぞれヒンジHを介して一体に繋がる蓋体である。この蓋体13は、図２(a)の矢印D₂に示すように、ヒンジＨを起点に揺動すると共に、蓋体13の閉じ状態を維持する係合手段ｆ（図３参照。）として、蓋体13の閉じ状態にあっては、ベース11の前方に設けた係止凸部f₁₁と係合し、その係合を所定の力で解除可能な係止凸部f₁₃が設けられている。 Reference numeral 13 denotes a lid having a width substantially equal to the recess C formed in the base 11 and integrally connected to the upper end portion 12e of the pressing plate 12 via hinges H as shown in FIG. . The lid 13, as shown by the arrow D ₂ in FIG. 2 (a), as well as swing hinge H as a starting point, as the engaging means f for maintaining the closed state of the lid 13 (see FIG. 3.) , in the closed state of the lid 13, locking projections f ₁₁ engages which is provided in front of the base 11, the engagement locking portion f ₁₃ releasable by a predetermined force provided ing.

これにより、図２(b)に示す蓋体13の閉じ状態は、押圧板12を窪みC₃に向けて押し込んで係合手段ｆを解除しない限り維持できる。なお、かかる係合手段ｆは、凸部同士の係合のみならず、凹部と凸部による係合であってもよい。 Thus, it closed state of the lid 13 shown in FIG. 2 (b), can be maintained unless the disengaging means f is pushed toward the C ₃ recess the presser plate 12. The engaging means f may be not only the engagement between the protrusions but also the engagement between the recesses and the protrusions.

蓋体13は、図１(a)に示すように、その裏面13fに、円形の凹部13aを有し、この円形の凹部13aの内側には、図２，３に示すように、蓋体13の閉じ状態において、５つの貫通孔11aを取り囲むように配置された環状の凸形状部13sが一体に形成されており、更に、その内側には、蓋体13の閉じ状態において、５つの貫通孔11aにそれぞれ間隔を空けて挿入可能な５つの突起13pが一体に形成されている。 As shown in FIG. 1 (a), the lid 13 has a circular recess 13a on its back surface 13f. Inside the circular recess 13a, as shown in FIGS. In the closed state, an annular convex portion 13s arranged so as to surround the five through-holes 11a is integrally formed. Further, in the closed state of the lid body 13 there are five through-holes. Five protrusions 13p that can be inserted into the 11a at intervals are integrally formed.

これにより、円形凹部13aの内側にて、図１(a)に示すように、間隔ΔY₁を空けて凸形状部13sを覆うように環状の弾性部材を設ければ、蓋体13の裏面13fに、５つの突起13pを取り囲むように配置され、当該蓋体13の閉じ状態において、ベース11に接触して突起13pの周りを密封する凸形状をしてなる環状の弾性部材1aが形成される。 Thus, at the inner side of the circular recess 13a, as shown in FIG. 1 (a), by providing the annular elastic member so as to cover the convex portion 13s at intervals [Delta] Y _1, the back surface 13f of the lid 13 The annular elastic member 1a is formed so as to surround the five protrusions 13p and has a convex shape that comes into contact with the base 11 and seals around the protrusions 13p when the lid body 13 is closed. .

従って、蓋体13を図２(b)のように閉じれば、図３に示すように、５つの突起13pがベース11の貫通孔11aそれぞれに間隔を空けた状態で挿入されることにより当該貫通孔11aでの目詰まりを防止し、更に、突起13pを取り囲んだ環状の弾性部材1aがベース11の外表面と接触することにより蓋体13を閉じた状態での気密性を確保することができる。 Therefore, if the lid 13 is closed as shown in FIG. 2B, the five protrusions 13p are inserted into the through holes 11a of the base 11 with a space therebetween as shown in FIG. It is possible to prevent clogging in the hole 11a and to ensure airtightness in a state where the lid 13 is closed by the annular elastic member 1a surrounding the protrusion 13p coming into contact with the outer surface of the base 11. .

なお、環状の弾性部材1aが、同形態のように、蓋体13の閉じ状態において、ベース11の外表面に接触する凸形状をしてなるものであれば、蓋体13を閉じた状態での接触は、凸形状をしてなる環状の弾性部材1aの頂部に集中するため、蓋体13を閉じた状態での気密性の確保を更に確実なものとすることができる。 If the annular elastic member 1a has a convex shape in contact with the outer surface of the base 11 in the closed state of the lid 13 as in the same form, the lid 13 is in the closed state. Since this contact is concentrated on the top of the annular elastic member 1a having a convex shape, it is possible to further ensure airtightness with the lid 13 closed.

なお、弾性部1aを凸形状としたことによる効果は、ベース11の外表面に環状の凸形状部を設け、環状の弾性部材1aが、蓋体13の閉じ状態において、ベース11に設けた前記凸形状部に接触する接触面を有してなるものであっても同様である。 The effect of the elastic portion 1a having a convex shape is that the annular convex portion is provided on the outer surface of the base 11, and the annular elastic member 1a is provided on the base 11 in the closed state of the lid body 13. The same applies to the case having a contact surface that contacts the convex portion.

そして、本参考技術では更に、環状の弾性部材1aの内側を覆うように弾性部材を設け、図１(a)等に示すように、弾性部材1aの内縁全周に、当該内縁の内側全体を満たすように繋がり、図３に示すように、当該蓋体13の閉じ状態において、ベース11との相互間に隙間ΔZ₁を形成する補助弾性部1bが一体に形成されている。 In this reference technique, an elastic member is further provided so as to cover the inside of the annular elastic member 1a, and as shown in FIG. 1 (a) and the like, the entire inner edge of the inner edge is disposed around the entire inner edge of the elastic member 1a. As shown in FIG. 3, auxiliary elastic portions 1 b that form a gap ΔZ ₁ with the base 11 are integrally formed with the lid 13 in the closed state, as shown in FIG. 3.

加えて、蓋体13の裏面13fには、図１(a)に示すように、円形の凹部13aからヒンジＨとの連結端部に至るまで切り欠かれた延長凹部13bが形成されている。そして、押圧板12の上端部12eには、図１(b)に示すように、延長凹部13bと整列する切り欠き凹部12bが形成されており、更に、上端部12eの窪みC₃側には、破線で示すように、切り欠き凹部12bと直交するように押圧板12の幅方向に沿って切り欠かれた段部12cが形成されている。 In addition, on the back surface 13f of the lid 13, an extended recess 13b that is cut out from the circular recess 13a to the connecting end with the hinge H is formed as shown in FIG. Then, the upper end portion 12e of the pressure plate 12, as shown in FIG. 1 (b), the cutout recess 12b align with the extension recess 13b and is formed, further, the recess C ₃ side of the upper unit 12e As shown by a broken line, a stepped portion 12c is formed that is cut along the width direction of the pressing plate 12 so as to be orthogonal to the cutout concave portion 12b.

これにより、押圧板12の窪みC₃側上端部12eに弾性部材を保持固定すれば、図１(a)に示すように、押圧板12の幅方向に沿って延在する横架弾性部1cが一体に形成され、更に、この横架弾性部1cの端部1eをそれぞれ、窪みC₃を形成する側縁e₂に保持固定すれば、押圧板12は、窪みC₃に向けての押し込みに抗する付勢力を得ることができる。 Thus, if the holding fix the elastic member in the recess C ₃ side upper portion 12e of the pressure plate 12, as shown in FIG. 1 (a), lateral bridging elastic portion 1c extending along the width direction of the pressing plate 12 There are integrally formed, further, each of the end 1e of the lateral bridging elastic portions 1c, if held fixed to the side edge e ₂ which forms a depression C _3, the pressing plate 12 is pushed in towards the recess C ₃ It is possible to obtain an urging force that resists.

しかも、押圧板12の上端部12eには、上述のように、切り欠き凹部12bが形成されているため、環状の弾性部材1aから延長凹部13b のΔY₂だけ内側を当該延長凹部13bに沿って延長し切り欠き凹部12bを通して横架弾性部1cに繋げれば、環状の弾性部材1aからベース11に繋がり蓋体13を開き状態に付勢する弾性延長部1dが一体に形成されることになる。 Moreover, the upper end portion 12e of the pressure plate 12, as described above, since the notched concave portion 12b is formed, the inner only [Delta] Y ₂ extended recess 13b from the annular elastic member 1a along the extended recess 13b If it is extended and connected to the horizontal elastic portion 1c through the cutout recess 12b, an elastic extension portion 1d that connects the annular elastic member 1a to the base 11 and biases the lid 13 in an open state is integrally formed. .

従って、環状の弾性部材1aが弾性延長部1dを介して横架弾性部1cに繋がることにより、蓋体13は、係合手段ｆが解除されると、蓋体13の閉じ状態で図２(b)に示すように折り曲げられていた弾性延長部1dの弾性復帰に伴う付勢力により、初期の位置まで自動的に広がるため、上述した効果を奏する操作性に優れたヒンジキャップを提供することができる。しかも、横架弾性部1cは、窪みC₃に向けて押し込んだ押圧板12をその撓みに抗する復元力で復帰すべく付勢力を与えるため、材質の異なる弾性材料を適宜選択するだけで、目的や用途に応じて、押圧板12の押し込みによる操作感を重視するタイプ、押し込みがスムースな操作性を重視するタイプに容易に変更することができる。 Accordingly, when the annular elastic member 1a is connected to the horizontal elastic portion 1c via the elastic extension 1d, the lid 13 is in the closed state when the engaging means f is released as shown in FIG. As shown in b), the elastic extension portion 1d that has been bent is automatically expanded to the initial position due to the urging force accompanying the elastic return, so that it is possible to provide a hinge cap with excellent operability that exhibits the effects described above. it can. Moreover, lateral bridging elastic portion 1c to provide a biasing force so as to return by the restoring force against the recess C ₃ pressing plate 12 is pushed toward the deflection thereof, only appropriately selecting the different elastic materials in material, Depending on the purpose and application, it can be easily changed to a type that emphasizes the operational feeling by pressing the pressing plate 12, or a type that emphasizes smooth operability.

同形態は、図４に示すように、ベース11の外表面に、５つの貫通孔11aを取り囲むように環状の弾性部材を埋め込んで、蓋体13の閉じ状態において、蓋体13に設けた環状の凸形状部13sに接触してこれら貫通孔11aの周りを密封する環状の弾性部材2aを形成し、更に、環状の弾性部材2aの内側を覆うように弾性部材を設けることで、同図に示すように、環状の弾性部2aの内縁全周に、当該内縁の内側の５つの貫通孔11aを除いた全体を満たすように繋がり、蓋体13の閉じ状態において、図６に示すように、蓋体13の裏面13fとの相互間に隙間ΔZ₂を形成する補助弾性部2bを一体に形成し、環状の弾性部材2aと補助弾性部2bとの面を同一の接触面2fとしたものである（図５，６では便宜上、符号２として示す。）。 In the embodiment, as shown in FIG. 4, an annular elastic member is embedded in the outer surface of the base 11 so as to surround the five through holes 11a, and the annular body provided in the lid body 13 in the closed state of the lid body 13 The annular elastic member 2a that seals around the through-hole 11a in contact with the convex portion 13s is formed, and an elastic member is provided so as to cover the inside of the annular elastic member 2a. As shown in FIG. 6, the entire circumference of the inner edge of the annular elastic portion 2 a is connected so as to fill the entire area excluding the five through holes 11 a inside the inner edge. those formed integrally with the auxiliary resilient portion 2b to form a gap [Delta] Z _2, and the surfaces of the annular elastic member 2a and the auxiliary elastic portion 2b and the same contact surface 2f therebetween the back 13f of the lid 13 (In FIG. 5, 6, it shows as the code | symbol 2 for convenience.).

この場合も、図５(b)に示すように蓋体13を閉じれば、図６に示すように、５つの突起13pが貫通孔11aそれぞれに間隔を空けて挿入されることにより当該貫通孔11aでの目詰まりを防止し、更に、貫通孔11aを取り囲んだ環状の弾性部材2aがベース11の外表面と接触することにより蓋体13を閉じた状態での気密性を確保することができる。 Also in this case, if the lid 13 is closed as shown in FIG. 5B, the five protrusions 13p are inserted into the through holes 11a at intervals as shown in FIG. In addition, the annular elastic member 2a surrounding the through hole 11a is in contact with the outer surface of the base 11, so that the airtightness in the closed state of the lid 13 can be ensured.

なお、環状の弾性部材2aは、図５，６に示すように、蓋体13の閉じ状態において、当該蓋体13の裏面13fに設けた環状の凸形状部13sに接触する接触面2fを有してなるものであるから、蓋体13を閉じた状態での接触は、凸形状部13sの頂部と接触する接触面2fに集中するため、蓋体13を閉じた状態での気密性の確保を更に確実なものとすることができるが、環状の弾性部材2aが、蓋体13の閉じ状態において、当該蓋体13の裏面13fに接触する凸形状をしてなるものとしても、蓋体13を閉じた状態での接触は、凸形状をしてなる環状の弾性部材2aの頂部に集中するため、同様の効果を奏する。 5 and 6, the annular elastic member 2a has a contact surface 2f that comes into contact with the annular convex portion 13s provided on the back surface 13f of the lid body 13 when the lid body 13 is closed. Therefore, the contact in the closed state of the lid 13 is concentrated on the contact surface 2f in contact with the top of the convex portion 13s, so that the airtightness in the closed state of the lid 13 is ensured. Even if the annular elastic member 2a has a convex shape in contact with the back surface 13f of the lid 13 in the closed state, the lid 13 Since the contact in the closed state concentrates on the top of the annular elastic member 2a having a convex shape, the same effect can be obtained.

また、補助弾性部2bに形成した貫通孔は、図６に示すように、突起13sに対して大径となり、当該突起13sとの間に目詰まりを防止すべく上述の隙間が形成されることが好ましい。 Further, as shown in FIG. 6, the through hole formed in the auxiliary elastic portion 2b has a large diameter with respect to the protrusion 13s, and the above-described gap is formed between the protrusion 13s and the protrusion 13s to prevent clogging. Is preferred.

図７(a),(b)はそれぞれ、本発明の第二の形態であるワンタッチキャップ30を、蓋体13の開き状態で示す上面図及び、同キャップ30を、ヒンジＨを断面として示す背面図である。また、図８(a),(b)はそれぞれ、図７(a)のＸ−Ｘ断面図及び、蓋体13の閉じ状態を図７(a)のＸ−Ｘ断面で示す断面図である。更に、図９は、図８(b)の拡大断面図である。なお、以下の説明においても、他の図面と同一部分は、同一符号をもって、その説明を省略する。 FIGS. 7A and 7B are a top view showing the one-touch cap 30 according to the second embodiment of the present invention with the lid 13 opened, and a back view showing the cap 30 with the hinge H as a cross section. FIG. FIGS. 8A and 8B are a cross-sectional view taken along line XX in FIG. 7A and a cross-sectional view showing the closed state of the lid body 13 taken along the line XX in FIG. . Further, FIG. 9 is an enlarged cross-sectional view of FIG. In the following description, the same parts as those in other drawings are denoted by the same reference numerals, and the description thereof is omitted.

同形態は、図７に示すように、５つの環状の弾性部材3aがそれぞれ、その内縁を貫通孔11aの口径に対応してなり、当該弾性部材3aの外縁全周に、当該外縁の外側全体をシート状に繋ぐ補助弾性部3bを一体に設けてなるものである。補助弾性部3bは、図８に示すように、ベース11の外表面に形成した凹部11dに埋め込まれる凸部3dを有し、図９に示すように、５つの環状の弾性部材3aがそれぞれ、蓋体13の閉じ状態において、蓋体13の裏面13fに接触して各突起13pの周りを密封すると共に、蓋体13の裏面13fとの相互間に隙間ΔZ₃を形成するものである。 In this embodiment, as shown in FIG. 7, each of the five annular elastic members 3a has an inner edge corresponding to the diameter of the through hole 11a, and the entire outer edge of the outer edge is arranged around the entire outer edge of the elastic member 3a. The auxiliary elastic portion 3b that connects the two in a sheet form is integrally provided. As shown in FIG. 8, the auxiliary elastic part 3b has a convex part 3d embedded in a concave part 11d formed on the outer surface of the base 11, and as shown in FIG. In the closed state of the lid 13, the back surface 13 f of the lid 13 is contacted to seal around each protrusion 13 p and a gap ΔZ ₃ is formed between the lid 13 and the back surface 13 f.

この場合も、蓋体13を図８(b)に示すように閉じれば、図９に示すように、５つの突起13pが貫通孔11aそれぞれに間隔を空けて挿入されることにより当該貫通孔11aでの目詰まりを防止し、更に、突起13pを取り囲んだ環状の弾性部材3aが蓋体13の裏面13fと接触することにより蓋体13を閉じた状態での気密性を確保することができる。 Also in this case, if the lid 13 is closed as shown in FIG. 8 (b), as shown in FIG. 9, the five protrusions 13p are inserted into the through-holes 11a at intervals, thereby the through-holes 11a. In addition, the annular elastic member 3a surrounding the protrusion 13p is in contact with the back surface 13f of the lid 13 so that airtightness in the closed state of the lid 13 can be ensured.

このため、環状の弾性部材3aの内径も、図９に示すように、突起13sに対して大径となり、当該突起13sとの間に隙間が形成されることが好ましい。 Therefore, it is preferable that the inner diameter of the annular elastic member 3a is larger than the protrusion 13s as shown in FIG. 9, and a gap is formed between the protrusion 13s and the protrusion 13s.

なお、環状の弾性部3aは、図８，９に示すように、蓋体13の閉じ状態において、当該蓋体13の裏面13fに接触する凸形状をしてなるものであるから、蓋体13を閉じた状態での接触は、凸形状をしてなる環状の弾性部材3aの頂部に集中するため、蓋体13を閉じた状態での気密性の確保を更に確実なものとすることができるが、環状の弾性部材3aが、蓋体13の閉じ状態において、当該蓋体13の裏面13fに個々の突起13p周りに設けた環状の凸形状部13sに接触する前述した接触面2fと同様の接触面を有してなるものとしても、蓋体13を閉じた状態での接触は、凸形状部13sの頂部と接触する環状の弾性部材3aの接触面に集中するため、同様の効果を奏する。 As shown in FIGS. 8 and 9, the annular elastic portion 3 a has a convex shape that comes into contact with the back surface 13 f of the lid body 13 in the closed state of the lid body 13. Since the contact in the closed state is concentrated on the top of the annular elastic member 3a having a convex shape, the airtightness in the closed state of the lid 13 can be further ensured. However, in the closed state of the lid body 13, the annular elastic member 3a is in contact with the annular convex shape portion 13s provided around the individual projections 13p on the back surface 13f of the lid body 13 in the same manner as the contact surface 2f described above. Even if it has a contact surface, the contact in a state where the lid 13 is closed concentrates on the contact surface of the annular elastic member 3a that contacts the top of the convex portion 13s, and thus has the same effect. .

補助弾性部3bは更に、図７に示すように、窪みＣに沿って伸びる２つの延長弾性部3cを一体に有し、これら延長弾性部3cが、横架弾性部1cの端部1eそれぞれに一体に繋がる。この場合、操作性や操作感について、第一の形態と同様の効果を奏する。 As shown in FIG. 7, the auxiliary elastic portion 3b further has two extended elastic portions 3c extending along the recess C, and these extended elastic portions 3c are respectively attached to the end portions 1e of the horizontal elastic portion 1c. Connect together. In this case, the same operability and operational feeling as in the first embodiment can be obtained.

上述したところは、本発明の好適な形態をしたものであるが、特許請求の範囲において、種々の変更を加えることができる。例えば、弾性部材としてはエラストマが挙げられるが、密封性や耐久性を考慮すれば、弾性を有する種々の材質のものが適用できる。また、環状の弾性部材と各弾性部は、インサート成形等により一体に形成することができ、更に、環状の弾性部材のみを単独のパーツとすることもできる。加えて、キャップの構造も蓋体の開きが自動で行われるワンタッチキャップに限らず、蓋体の開きが自動で行われないヒンジキャップに適用することもできる。 The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims. For example, an elastomer may be used as the elastic member, but various materials having elasticity can be applied in consideration of sealing performance and durability. In addition, the annular elastic member and each elastic portion can be integrally formed by insert molding or the like, and only the annular elastic member can be a single part. In addition, the cap structure is not limited to the one-touch cap in which the lid is automatically opened, and can be applied to a hinge cap in which the lid is not automatically opened.

更に、上述した各構成はそれぞれ、目的及び用途に応じて、例えば、参考技術の延長弾性部1dと第一の形態の弾性部材2aとの組み合わせや、第二の形態の延長弾性部3cと参考技術の延長弾性部1dとの置換等、適宜組み合わせや置換等の変更を行うことができる。 Furthermore, each of the above-described configurations is, for example, a combination of the extended elastic part 1d of the reference technique and the elastic member 2a of the first form, or the extended elastic part 3c of the second form and the reference according to the purpose and application. It is possible to appropriately change the combination or replacement, such as replacement with the extended elastic portion 1d of the technology.
