Description

本発明は、容器本体の口部に着脱可能に装着されるキャップ及び容器のキャップ部構造に関する。   The present invention relates to a cap that is detachably attached to a mouth portion of a container main body and a cap portion structure of the container.

一般に、液体洗剤、液体漂白剤、液体柔軟剤、溶剤等の液状物や、粒状洗剤、粒状漂白剤、粒状調味料等の粉粒物を収納する容器では、容器本体の口部にキャップを螺合により着脱可能に装着し、このキャップの着脱によって口部を開閉させる。前記キャップの中には、有蓋筒状の計量部の外周に螺合筒部を配置し、計量部における螺合筒部よりも上方（容器外方）に位置する周壁部を外殻部で覆って二重構造としたものがある（例えば、特許文献１参照）。この場合、単なる筒状の計量部の外観に円みを持たせる等のデザイン自由度を高めることができる。   Generally, in containers that store liquid products such as liquid detergents, liquid bleaches, liquid softeners, and solvents, and granular materials such as granular detergents, granular bleaches, and granular seasonings, a cap is screwed into the mouth of the container body. Attachable and detachable, and the mouth is opened and closed by attaching and detaching this cap. In the cap, a screwed tube portion is arranged on the outer periphery of the covered cylindrical measuring portion, and the outer wall portion covers the peripheral wall portion located above the screwed tube portion (outside the container) in the measuring portion. Some have a double structure (see, for example, Patent Document 1). In this case, it is possible to increase the degree of freedom of design such as giving the outer appearance of a simple cylindrical measuring part round.

実用新案登録第３１５２６３９号公報Utility Model Registration No. 3152639

ところで、上記従来の構成において、比較的大径の螺合筒部の外面ではなく、その上方の外殻部の外面を把持してキャップを回転させる使用者が散見される。しかし、外殻部が円みのある外観の場合は特に、手指が滑り易いことが考えられ、キャップの開閉のし易さの面で改良の余地がある。
また、計量部の周壁部の内周面には刻印や印字による計量目盛が記されるが、キャップが透明又は半透明であっても、計量部の周壁部が外殻部で覆われた二重構造である場合には、キャップ外方から計量目盛が視認し難く、この点でも改良の余地がある。 By the way, in the above conventional configuration, there are some users who rotate the cap by gripping the outer surface of the upper shell portion rather than the outer surface of the relatively large-diameter threaded tube portion. However, especially when the outer shell has a rounded appearance, it is considered that the fingers are likely to slip, and there is room for improvement in terms of ease of opening and closing the cap.
In addition, a measurement scale by engraving or printing is written on the inner peripheral surface of the peripheral wall portion of the measuring unit, but even if the cap is transparent or translucent, the peripheral wall portion of the measuring unit is covered with the outer shell part. In the case of a heavy structure, the measurement scale is difficult to visually recognize from the outside of the cap, and there is room for improvement in this respect.

そこで本発明は、容器本体の口部に着脱可能に装着されるキャップ及び容器のキャップ部構造において、キャップの開閉のし易さ、及びキャップ内側の計量目盛の視認のし易さを向上させることを目的とする。   Therefore, the present invention improves the ease of opening and closing of the cap and the visibility of the measurement scale inside the cap in the cap and container cap structure that is detachably attached to the mouth of the container body.

On the outer surface of the lid portion 21a, for example, five grounding convex portions 26 are formed that serve as legs when the measuring cap 20 is placed with the open end 21c of the measuring portion 21 facing upward. The grounding convex part 26 should just be at least three so that the measurement cap 20 can be mounted stably. The open end 21c of the measuring unit 21 is curved outward in the cap radial direction, and suppresses the wraparound to the outer surface of the peripheral wall 21b when the liquid content in the measuring unit 21 is poured out.

図３，４，６に示すように、外殻部２３は、例えばキャップ径方向で相対する二箇所に、それぞれキャップ軸方向と平行な切断面２７ａ，２７ｂに沿うように切り欠かれた切り欠き部２７を有する。換言すれば、外殻部２３は、計量部２１のボトル上方側におけるキャップ径方向で相対する二箇所にキャップ周方向で互いに離間して設けられる。   As shown in FIGS. 3, 4, and 6, the outer shell portion 23 is notched, for example, at two locations facing each other in the cap radial direction so as to be along cut surfaces 27 a and 27 b parallel to the cap axial direction. Part 27. In other words, the outer shell portion 23 is provided at two locations opposite to each other in the cap radial direction on the bottle upper side of the measuring portion 21 so as to be separated from each other in the cap circumferential direction.

両切断面２７ａ，２７ｂは互いに平行をなし、両切断面２７ａ，２７ｂ間の距離は計量部２１の外径よりも小とされる。両切り欠き部２７には、計量部２１の周壁部２１ｂのボトル上方側の一部が露出部２１ｄとして配置される。両露出部２１ｄのキャップ周方向両側方には、それぞれ切断面２７ａ，２７ｂに沿う立壁部２８が形成される。キャップ側螺合筒部２２のボトル下方側の開放端部２２ｄよりもボトル上方側において、キャップ内部空間がキャップ外面に開口することはない。計量キャップ２０は透明又は半透明に構成されており、両露出部２１ｄでは、周壁部２１ｂの内周面に刻印又は印字等により記された計量目盛をキャップ外方から視認可能である。計量キャップ２０は、少なくとも両露出部２１ｄが透明又は半透明に構成されていればよい。   Both the cut surfaces 27 a and 27 b are parallel to each other, and the distance between the both cut surfaces 27 a and 27 b is smaller than the outer diameter of the measuring portion 21. In the both cutout portions 27, a part of the peripheral wall portion 21b of the measuring portion 21 on the bottle upper side is arranged as an exposed portion 21d. Standing wall portions 28 are formed along the cut surfaces 27a and 27b on both sides of the exposed portions 21d in the cap circumferential direction. The cap internal space does not open to the outer surface of the cap on the bottle upper side of the open side 22d on the bottle lower side of the cap-side threaded cylinder portion 22. The measuring cap 20 is configured to be transparent or translucent, and in both exposed portions 21d, a measuring scale marked by marking or printing on the inner peripheral surface of the peripheral wall portion 21b is visible from the outside of the cap. The measuring cap 20 only needs to be configured so that at least both exposed portions 21d are transparent or translucent.

図３中符号Ｗは切断面２７ａ，２７ｂと直交する方向から見たときの露出部２１ｄの幅を、符号Ｆは切断面２７ａ，２７ｂに沿う方向から見たときの外殻部２３の幅をそれぞれ示す。露出部２１ｄの幅Ｗは、視認性や成型時の抜き勾配等を考慮すると、少なくとも２ｍｍは確保することが望ましい。   In FIG. 3, symbol W denotes the width of the exposed portion 21d when viewed from the direction orthogonal to the cut surfaces 27a and 27b, and symbol F denotes the width of the outer shell portion 23 when viewed from the direction along the cut surfaces 27a and 27b. Each is shown. The width W of the exposed portion 21d is preferably at least 2 mm in consideration of visibility, draft angle during molding, and the like.

図５を参照し、図中線Ｌ１はキャップ螺合筒部の上端角部と外殻部２３の外面とに接する接線を示し、図中線Ｒ１は接線Ｌ１と外殻部２３との接点Ｔ１を通過するキャップ周方向に沿う仮想円を示す（図２，３参照）。両切り欠き部２７は仮想円Ｒ１を切り欠いており、キャップを接線Ｌ１に沿う平面上に載置した際の転がりを抑止する。計量キャップ２０の外面には、滑り止めのためのローレット（ナール）やリブが形成されてもよいが、少なくとも両露出部２１ｄの外面は、計量目盛を見易くするために平滑であることが望ましい。   Referring to FIG. 5, a line L1 in the figure indicates a tangent line in contact with the upper end corner of the cap screwing cylinder part and the outer surface of the outer shell part 23, and a line R1 in the figure indicates a contact T1 between the tangent line L1 and the outer shell part 23. An imaginary circle that passes through the cap circumferential direction is shown (see FIGS. 2 and 3). Both notches 27 cut out the virtual circle R1, and suppress rolling when the cap is placed on a plane along the tangent L1. Knurls or ribs for preventing slipping may be formed on the outer surface of the measuring cap 20, but it is desirable that at least the outer surfaces of both exposed portions 21d be smooth in order to make the measuring scale easy to see.

図１，２を参照し、キャップ側螺合筒部２２の円筒状の外周面は、ボトル下方側の開放端部２２ｄから回り込んだ内容物が付着した場合、計量キャップ２０の着脱時に把持した手指が滑り易くなる。
これに対し、上記計量キャップ２０では、キャップ側螺合筒部２２の開放端部２２ｄから離間した外殻部２３の両切り欠き部２７を把持部とすることで、内容物の付着が抑えられると共に、キャップ側螺合筒部２２の円筒状の外周面よりも手指で摘み易く、かつキャップ周方向と交差する立壁部２８によってトルクも入力し易い。 Referring to FIGS. 1 and 2, the cylindrical outer peripheral surface of the cap-side threaded cylindrical portion 22 is gripped when the measuring cap 20 is attached / detached when the contents wrapped around from the open end 22 d on the bottle lower side are attached. Fingers become slippery.
On the other hand, in the measurement cap 20, the notch portions 27 of the outer shell portion 23 separated from the open end portion 22 d of the cap-side threaded cylinder portion 22 are used as gripping portions, thereby preventing the content from adhering. Further, it is easier to pick with fingers than the cylindrical outer peripheral surface of the cap-side threaded cylindrical portion 22, and torque can be easily input by the standing wall portion 28 that intersects the circumferential direction of the cap.

すなわち、上記計量キャップ２０では、手指の滑りが十分に抑止され、かつ回転操作がし易く、口部３の開閉が容易になる。
また、計量部２１の周壁部２１ｂを覆う外殻部２３を部分的に切り欠き、計量部２１の周壁部２１ｂに部分的な露出部２１ｄを設けることで、計量部２１の周壁部２１ｂが全周に渡って外殻部２３で覆われた二重構造である場合と比べて、計量部２１内の計量目盛や内容物が視認し易くなる。 That is, in the measuring cap 20, the sliding of fingers is sufficiently suppressed, the rotation operation is easy, and the opening / closing of the mouth portion 3 is facilitated.
In addition, the outer shell portion 23 covering the peripheral wall portion 21b of the measuring portion 21 is partially cut out, and a partial exposed portion 21d is provided on the peripheral wall portion 21b of the measuring portion 21 so that the peripheral wall portion 21b of the measuring portion 21 is entirely removed. Compared with the case of a double structure covered with the outer shell part 23 over the circumference, the measurement scale and contents in the measurement part 21 are easily visible.

上記計量キャップ２０はトルクを入力し易いことから、計量キャップ２０が強く締め込まれてしまうことが考えられる。そこで、上記計量キャップ付き容器１では、外口部１１の第三ネジ山１１ａ及びキャップ側螺合筒部２２の第四ネジ山２２ａの少なくとも一方の螺合終端部に、他方の螺合先端部をキャップ周方向で突き当てる規制壁部が突設される。   Since the measuring cap 20 is easy to input torque, it is conceivable that the measuring cap 20 is strongly tightened. Therefore, in the container 1 with the measuring cap, the other screwing tip end portion is at least one screwing end portion of the third screw thread 11a of the outer opening portion 11 and the fourth screw thread 22a of the cap side screwing tube portion 22. A restricting wall portion is provided so as to protrude in the circumferential direction of the cap.

図１０に示す例では、外口部１１の第三ネジ山１１ａの螺合終端部１１ｃに、キャップ側螺合筒部２２の第四ネジ山２２ａの螺合先端部２２ｂをボトル周方向で突き当てる規制壁部３１が連設される。この規制壁部３１とキャップ側螺合筒部２２の第四ネジ山２２ａの螺合先端部２２ｂとで、計量キャップ２０の締め込み停止位置を規定する規定部３１Ａが構成される。   In the example shown in FIG. 10, the screwing tip end part 22 b of the fourth screw thread 22 a of the cap side screwing cylinder part 22 is pushed in the bottle circumferential direction on the screwing end part 11 c of the third screw thread 11 a of the outer opening part 11. A regulation wall portion 31 to be hit is provided continuously. The regulation wall portion 31 and the screwing tip portion 22b of the fourth screw thread 22a of the cap-side screwing tube portion 22 constitute a defining portion 31A that defines the tightening stop position of the measuring cap 20.

逆に、キャップ側螺合筒部２２の第四ネジ山２２ａの螺合終端部２２ｃに、外口部１１の第三ネジ山１１ａの螺合先端部１１ｂをキャップ周方向で突き当てる規制壁部（不図示）が連設され、この規制壁部と外口部１１の第三ネジ山１１ａの螺合先端部１１ｂとで前記規定部が構成されてもよい。   On the contrary, a regulating wall portion that abuts the screwing end portion 11b of the third screw thread 11a of the outer opening portion 11 against the screwing end portion 22c of the fourth screw screw 22a of the cap side screwing tube portion 22 in the cap circumferential direction. (Not shown) may be provided in a row, and the regulation portion may be configured by the restriction wall portion and the screwing tip portion 11b of the third screw thread 11a of the outer port portion 11.

前記規定部は、各ネジ山を利用したものに限らず、例えば図１１に示すように、キャップ側螺合筒部２２のボトル下方側の開放端部２２ｄに係合部３３を突設すると共に、開放端部２２ｄとキャップ軸方向で対向する本体側フランジ部８の上面部８ａに係合部３３をキャップ周方向で突き当てる被係合部３４を突設し、これら係合部３３及び被係合部３４とで、計量キャップ２０の締め込み停止位置を規定する規定部３４Ａを構成してもよい。   For example, as shown in FIG. 11, the defining portion is not limited to one using each screw thread, and an engaging portion 33 protrudes from an open end 22 d on the bottle lower side of the cap-side threaded cylindrical portion 22. Further, an engaged portion 34 for projecting the engaging portion 33 in the circumferential direction of the cap is provided on the upper surface portion 8a of the main body side flange portion 8 facing the open end portion 22d in the cap axial direction. The engaging portion 34 may constitute a defining portion 34A that defines a tightening stop position of the measuring cap 20.

また、前記規定部はキャップ周方向での突き当てに限らず、例えばキャップ側螺合筒部２２のボトル下方側の開放端部２２ｄとこれをキャップ軸方向で突き当てる本体側フランジ部８の上面部８ａとで前記規定部を構成したり、計量部２１の開放端部２１ｃとこれをキャップ軸方向で突き当てる挿入部９の底部とで前記規定部を構成したり、樋部１０の先端部１０ａとこれをキャップ軸方向で突き当てる計量部２１の蓋部２１ａとで前記規定部を構成してもよい。さらに、前述の各規定部の構成を適宜組み合わせて用いてもよい。   The defining portion is not limited to abutment in the cap circumferential direction, and for example, an open end 22d on the bottle lower side of the cap-side threaded tube portion 22 and an upper surface of the main body side flange portion 8 that abuts this in the cap axial direction. The defining portion is constituted by the portion 8a, the defining portion is constituted by the open end portion 21c of the measuring portion 21 and the bottom portion of the insertion portion 9 that abuts the measuring portion 21 in the cap axial direction, or the distal end portion of the flange portion 10 You may comprise the said prescription | regulation part with 10a and the cover part 21a of the measurement part 21 which abuts this in a cap axial direction. Furthermore, you may use combining the structure of each above-mentioned prescription | regulation part suitably.

以上説明したように、上記実施形態における計量キャップ２０によれば、計量部２１における容器外方（容器本体２及び計量キャップ２０の外方）に位置する蓋部２１ａ側の周壁部２１ｂを覆う外殻部２３を備えることで、周壁部２１ｂを型抜き等を考慮した単純な円筒状にしながらも外殻部２３によりデザイン自由度を高めることができると共に、外殻部２３が計量部２１の周壁部２１ｂをキャップ周方向で部分的に露出させる切り欠き部２７を有する（外殻部２３がキャップ周方向で部分的に設けられる）ことで、両切り欠き部２７を把持部として手指で摘み易くし、かつトルク入力もし易くすることができる。これにより、計量キャップ２０の回転操作をし易くして口部３の開閉を容易にすることができる。また、外殻部２３の切り欠き部２７にキャップ周方向と交差する立壁部２８を設けることで、計量キャップ２０へのトルク入力をより容易にして回転操作を容易にすることができる。   As described above, according to the measuring cap 20 in the above embodiment, the outer portion covering the peripheral wall portion 21b on the lid portion 21a side located outside the container in the measuring portion 21 (outside the container main body 2 and the measuring cap 20). By providing the shell portion 23, the outer shell portion 23 can increase the degree of design freedom while making the peripheral wall portion 21 b a simple cylindrical shape considering die cutting and the like, and the outer shell portion 23 is a peripheral wall of the measuring portion 21. By having a cutout portion 27 that partially exposes the portion 21b in the circumferential direction of the cap (the outer shell portion 23 is partially provided in the circumferential direction of the cap), the two cutout portions 27 can be easily gripped with fingers. In addition, torque input can be facilitated. Thereby, the rotation operation of the measuring cap 20 can be facilitated, and the opening and closing of the mouth portion 3 can be facilitated. In addition, by providing the standing wall portion 28 that intersects the circumferential direction of the cap in the cutout portion 27 of the outer shell portion 23, it is possible to more easily input torque to the measuring cap 20 and facilitate the rotation operation.

また、透明又は半透明の周壁部２１ｂが外殻部２３に覆われることなくキャップ外方に露出することで、計量部２１の周壁部２１ｂが全周に渡って外殻部２３に覆われた二重構造である場合と比べて計量部２１内の計量目盛や内容物が視認し易くなり、計量キャップ２０の使い勝手を向上させることができる。   Further, the transparent or translucent peripheral wall portion 21b is exposed outside the cap without being covered by the outer shell portion 23, so that the peripheral wall portion 21b of the measuring portion 21 is covered by the outer shell portion 23 over the entire circumference. Compared with the case of the double structure, the measurement scale and contents in the measurement unit 21 are easily visible, and the usability of the measurement cap 20 can be improved.

なお、本発明は上記実施形態に限られるものではなく、例えば、外殻部２３の切り欠き部２７は二箇所に限らず、図７に示す計量キャップ１２０のように、切り欠き部２７が一箇所であってもよい。切り欠き部２７は三箇所以上であってもよいが、手指の掛かり易さや露出部２１ｄのキャップ周方向の幅による計量部２１の見易さを考慮すると、切り欠き部２７の数は少数であることが望ましい。
また、図８に示す計量キャップ２２０のように、外殻部２３とキャップ側螺合筒部２２との間のキャップ側フランジ部２４による段差を無くし、外殻部２３の外面とキャップ側螺合筒部２２の外面とを面一に形成することで、円みのある外観を強調した構成としてもよい。
他方、図９に示す計量キャップ３２０のように、計量部２１の蓋部２１ａを平坦状にして角張った外観にすると共に、計量部２１の開放端部２１ｃを上方に向けて計量キャップ２０を載置する際の安定性を高めた構成としてもよい。 Note that the present invention is not limited to the above-described embodiment. For example, the cutout portion 27 of the outer shell portion 23 is not limited to two places, and a single cutout portion 27 is provided like a measuring cap 120 shown in FIG. It may be a place. The number of the notch portions 27 may be three or more. However, in consideration of the ease with which a finger is caught and the visibility of the measuring portion 21 due to the width of the exposed portion 21d in the cap circumferential direction, the number of the notch portions 27 is small. It is desirable to be.
Further, unlike the measuring cap 220 shown in FIG. 8, the step by the cap side flange portion 24 between the outer shell portion 23 and the cap side screwing tube portion 22 is eliminated, and the outer surface of the outer shell portion 23 and the cap side screwing are removed. It is good also as a structure which emphasized the external appearance with roundness by forming the outer surface of the cylinder part 22 flush | planar.
On the other hand, like the measuring cap 320 shown in FIG. 9, the lid 21 a of the measuring unit 21 is flattened to have an angular appearance, and the measuring cap 20 is mounted with the open end 21 c of the measuring unit 21 facing upward. It is good also as a structure which improved the stability at the time of placing.

本発明は、計量具として用いないキャップ及び該キャップを具備するキャップ付き容器に適用してもよい。キャップ及び口部の螺合構造は、キャップ側を雄ネジ、口部側を雌ネジとした構成でもよい。キャップを螺合により回転係合させるスクリューキャップ構造に限らず、例えばバヨネット係合等の回転係合を用いた構造でもよい。ノズルキャップを有さない容器本体（ボトル体）の口部に直接キャップを装着する容器に適用してもよい。
そして、上記実施形態における構成は本発明の一例であり、当該発明の要旨を逸脱しない範囲で種々の変更が可能である。 The present invention may be applied to a cap that is not used as a measuring tool and a container with a cap that includes the cap. The screwed structure of the cap and the mouth may be configured such that the cap side is a male screw and the mouth side is a female screw. The structure is not limited to the screw cap structure in which the cap is rotationally engaged by screwing, but may be a structure using rotational engagement such as bayonet engagement. You may apply to the container which attaches a cap directly to the opening part of the container main body (bottle body) which does not have a nozzle cap.
