Description

明細書 ' ピルファ一プル一フキャップ 技術分野  Description '' Pillow pull cap Technical field
この発明は、 キャップ本体の下端にプリッジ部を介してバンド部を設け たピルファ一プルーフキャップに関するものである。 背景技術  The present invention relates to a pill-proof cap having a band at the lower end of a cap body via a ridge. Background art
メカニカルに瓶口に係止するタイプのピルファープル一フキヤップのバ ンド部は、 開栓時、 あるいはいたずらに対して強固に瓶口にグリップしな ければならない。 すなわち、 開栓時、 例えば不連続の状態でバンド部下端 から折曲して内向き上方向に立ち上げた複数個の立ち上げ部が瓶口の膨出 部 （ボトルネック， ビード） からすつぼ抜けないよう、 かつ、 キャップ本 体およびバンド部間に設けた複数個のブリッジ部に上下方向 （縦方向） の 弓 Iつ張り力がかかつてブリッジ部が確実に破断するよう、前記各立ち上げ 部の先端部分を膨出部の下周面に確実に係止する必要がある。  The band of the pill fur pull-up cap, which is mechanically locked to the bottle mouth, must be firmly gripped on the bottle mouth when opened or against tampering. In other words, at the time of opening, for example, in the discontinuous state, a plurality of rising portions bent from the lower end of the band portion and raised inward upward from the bulging portion of the bottle mouth (bottleneck, bead) to the crucible. Each of the above-mentioned rises so that the bridge part provided between the cap body and the band part does not come off, and a vertical (longitudinal) bow I tension force is applied to the plurality of bridge parts provided between the cap body and the band part so that the bridge part is reliably broken. It is necessary to securely lock the tip of the portion to the lower peripheral surface of the bulging portion.
このためには、 立ち上げ部の付根部から先端部まで、 第 1 5図 （A) に 示すような矩形状、 あるいは、 第 1 5図 （B ) に示すようなほぼ台形形状 の横断面を持つ、 細長い平板よりなる立ち上げ部 4 1， 4 2において、 座 屈 （立ち上げ部の縦方向に加わる圧力で横方向に順次変形を起こして折れ 曲がる現象） を防止するとともに、立ち上げ部 4 1 , 4 2が内側に倒れる 反転現象を防止するためには肉厚 a , bを上げるしか方法がなかった。 こ れは、 複数個の立ち上げ部をそれぞれ薄肉にすると立ち上げ部自体が座屈 するからである。 座屈は立ち上げ部の弱化部からはじまったり、 あるいは 立ち上げ部のバンド部への付根部（ヒンジ部） からはじまる。 し力、し、 立ち上げ部の厚肉化は、 キャップを瓶口に巻き締める際 （閉栓 の際） に瓶口のスカート部を乗り越えるときには障害となって、 キャップ を瓶口に嵌めるのが難しく、 このため厚肉化には自ずと制限があり、 極端 な厚肉化はできないことになる。 さらに、 立ち上げ部の前記付根部（ヒン ジ部） はきわめてわずかな空間に施すため、 また、立ち上げ部を前記付*** （ヒンジ部） から折り曲げるため、 立ち上げ部の前記付根部 （ヒンジ部To do this, a rectangular cross-section as shown in Fig. 15 (A) or a substantially trapezoidal cross-section as shown in Fig. 15 (B) is used from the root to the tip of the rising part. The buckling (the phenomenon that the rising portion is deformed sequentially in the horizontal direction due to the pressure applied in the vertical direction and bends) is prevented at the rising portions 4 1 and 4 2 of the rising portions 4 and 4. 1 and 4 2 fall inward The only way to prevent the reversal phenomenon was to increase the wall thicknesses a and b. This is because if the plurality of rising portions are made thinner, the rising portions themselves buckle. Buckling starts at the weakened part of the rising part or at the root (hinge part) of the rising part to the band. The thickening of the rising part is an obstacle to getting over the skirt part of the bottle mouth when tightening the cap around the bottle mouth (when closing), and it is difficult to fit the cap into the bottle mouth. For this reason, there is a natural limitation in thickening, and extremely thickening cannot be achieved. Further, since the root portion (hinge portion) of the rising portion is provided in a very small space, and the rising portion is bent from the root portion (hinge portion), the root portion (hinge portion) of the rising portion is formed.
) は薄肉になり易い。 ) Tends to be thin.
この発明は上述の事柄に留意してなされたもので、 その目的は、 閉栓時 には瓶口への取り付け （嵌まり込み） を容易にしてキヤッビング性能を向 上できるとともに、 開栓時には立ち上げ部の座屈および/または倒れを防 止しながら、瓶口へのグリップ性能を向上できるピルファープルーフキヤ ップを提供することである。 発明の開示  The present invention has been made in consideration of the above-mentioned matters, and its purpose is to facilitate attachment (fitting) to a bottle opening when the bottle is closed, improve the cabbing performance, and to start up when the bottle is opened. An object of the present invention is to provide a pill fur proof cap that can improve grip performance on a bottle mouth while preventing buckling and / or falling of a part.

The base portion 9 may be bent from the inner wall 4a of the band portion 4.
以下、 この発明の特徴的構成について説明する。  Hereinafter, the characteristic configuration of the present invention will be described.
上述したように、 バンド部 4から内向き上方向に連設した立ち上げ部 5 を、 バンド部 4の円周方向において不連続の状態で複数個設けてある。 そ して、 各立ち上げ部 5のバンド部 4への付根部分 9から先端部分 8まで、 横断面において、 全部がキャップ中央側に円弧の中心を持つ円弧となるよ う構成してある。 また、 付根部分 9を、 キャップ高さ方向 （両矢印 Tで示 す方向） に湾曲した円弧で、 かつ、上側へ向けて T\ 方向に凸状になるよ う構成してある 〔第 3図 （A)参照〕 。 As described above, a plurality of rising portions 5 that are continuously provided inward and upward from the band portion 4 are provided discontinuously in the circumferential direction of the band portion 4. Then, from the root portion 9 to the tip portion 8 of each rising portion 5 to the band portion 4, in the cross section, the whole is configured to be an arc having the center of the arc at the center of the cap. In addition, the base 9 is an arc that is curved in the cap height direction (the direction indicated by the double-headed arrow T) and that is convex in the T \ direction upward. [See Fig. 3 (A)].
詳しくは、 立ち上げ部 5は、横断面円弧状で、 円弧がキャップ中央側に 円弧の中心を持つよう薄肉で矩形の平板を湾曲させたような形状に形成さ れるとともに、 付根部分 9が上側へ向けて凸状になる円弧 9 a， 9 bを有 するよう形成されている。 すなわち、 立ち上げ部 5は、 薄肉で矩形の平板 をキャップ中央側から外側に向けて円弧状に凸状になるよう湾曲させた形 状、 つまり、横断面形状において外向き凸状の円弧状部分を有し、 第 3図 (A) に示すように、立ち上げ部 5の付根部分 9から先端部分 8まで、 横 断面において、全部がキャップ中央側に中心を持つ円弧となっている。 例 えば、 付根部分 9の平面視あるいは横断面形状は、 第 2図 （B) に示すよ うに外向きに突出した円弧状に形成されている。 しかも、付根部分 9は、 バンド部 4の下端に形成した裾 1 1から曲げられてキャップ高さ方向 （T 方向） の上側 ( T , 方向） へ向く凸状の湾曲部分 Sで構成されている。 こ の上に凸の湾曲部分 Sの上端および下端は、 それぞれ、 T , 方向に湾曲し た上下の円弧 9 aおよ 15び 9 bを有する。 そして、 付根部分 9も薄肉で形 成してある。  Specifically, the rising portion 5 has an arc-shaped cross-section, and is formed into a shape in which a thin rectangular plate is curved so that the arc has the center of the arc at the center of the cap, and the root portion 9 has an upper portion. It is formed to have arcs 9a and 9b that are convex toward. That is, the rising portion 5 has a shape in which a thin, rectangular flat plate is curved so as to protrude in an arc shape from the center of the cap toward the outside, that is, an arc-shaped portion having an outwardly convex cross-sectional shape. As shown in FIG. 3 (A), from the root portion 9 to the tip end portion 8 of the rising portion 5, the entire cross section is an arc centered on the center of the cap. For example, as shown in FIG. 2 (B), the root portion 9 has a plan view or a cross-sectional shape formed in an arc shape protruding outward. Moreover, the root portion 9 is formed of a convex curved portion S which is bent from the skirt 11 formed at the lower end of the band portion 4 and faces upward (T, direction) in the cap height direction (T direction). . The upper and lower ends of the upwardly curved portion S have upper and lower arcs 9a and 9b curved in the T, direction, respectively. And the base part 9 is also formed thin.
先端部分 8の横断面は、 瓶口 6の膨出部 7のリング状の下周面 （傾斜面 ) mの円弧 7 a , 7 a 〔第 4図 （A) 参照〕 に沿うよう円弧状に形成され ており、 開栓の初期 （キャップ開けはじめ） において、前記下周面 mに立 ち上げ部 5の上面 Pがほぼ当接するよう立ち上げ部 5の上面 Pを平面視円 弧状としてある。 すなわち、 第 4図 （A) に示すように、立ち上げ部上面 Pの円弧 8 aおよび 8 aを含むそれぞれ外円および内円と、 膨出部 7の下 周面 mを構成する円弧 7 aを含む円とはキャップ中央側の中心 0を共有す る同心円となっている。 これにより、 立ち上げ部上面 Pのほぼ全領域を下 周面 mにぴったりと強固に当接させることが可能である。 なお、 平面視の 形状が、 外向きに突出した円弧状であり、 かつ、 その曲率をキャップの中 央を中心 0とする円弧 8 aの曲率より大としてある第 4図 （A) に点線で 示した形状を持つ立ち上げ部上面 P ' であっても、 この立ち上げ部上面 P ， のほぼ全領域を下周面 mに強固に当接させることができる。 The cross section of the distal end portion 8 is formed in an arc shape so as to follow the arcs 7a and 7a (see Fig. 4 (A)) of the ring-shaped lower peripheral surface (inclined surface) m of the bulging portion 7 of the bottle mouth 6. The upper surface P of the rising portion 5 is formed in an arc shape in a plan view so that the upper surface P of the rising portion 5 almost comes into contact with the lower peripheral surface m at the initial stage of opening the cap (beginning of opening the cap). That is, as shown in FIG. 4 (A), an outer circle and an inner circle including the arcs 8a and 8a of the rising surface upper surface P and an arc 7a forming the lower peripheral surface m of the bulging portion 7, respectively. Is a concentric circle sharing the center 0 on the center side of the cap. Thereby, almost the entire area of the upper surface P of the rising portion can be exactly and firmly brought into contact with the lower peripheral surface m. The shape in plan view is an arc that protrudes outward, and the curvature is Even if the upper surface P ′ of the rising portion has the shape shown by the dotted line in FIG. 4 (A), which is larger than the curvature of the arc 8a centered at the center 0, almost all of the upper surface P, The region can be firmly brought into contact with the lower peripheral surface m.
なお、 この実施形態の立ち上げ部 5は、横断面形状において、 外向き凸 状の部分を有し、 付根部分 9は、 キャップ高さ方向 （T方向） に湾曲し、 かつ、 第 5図にも示すように、 上側へ向けて 方向に凸状になるよう構 成してあればよく、立ち上げ部上面 Pの形状は適宜設定できる。  Note that the rising portion 5 of this embodiment has an outwardly convex portion in the cross-sectional shape, the root portion 9 is curved in the cap height direction (T direction), and FIG. As shown also, it is sufficient if the configuration is such that it is convex in the upward direction, and the shape of the rising portion upper surface P can be set as appropriate.
すなわち、 立ち上げ部上面 Pを、 第 5図 （A) に示すように、 立ち上げ 部 5の高さ方向 （T方向） に垂直な平面に形成してもよい。 この場合、 立 ち上げ部 5の先端部分 8のみ横断面において矩形状とし、 第 4図 （B ) に 示すように、 立ち上げ部上面 P， ' を平面視矩形形状に形成してもよい。 また、 第 5図 （B ) に示すように、 立ち上げ部上面 Pを、 瓶口の膨出部 7の下周面 （係止面） mに面接触するよう下方に凹入する凹入面に形成し てもよい。 また、 第 5図 （C ) に示すように、 立ち上げ部上面 Pを、上方 に凸出する凸出面に形成してもよい。  That is, the rising portion upper surface P may be formed on a plane perpendicular to the height direction (T direction) of the rising portion 5 as shown in FIG. 5 (A). In this case, only the leading end portion 8 of the rising portion 5 may be rectangular in cross section, and the rising portion upper surface P, ′ may be formed in a rectangular shape in plan view, as shown in FIG. 4 (B). Also, as shown in FIG. 5 (B), the upper surface P of the rising portion is a concave surface which is recessed downward so as to make surface contact with the lower peripheral surface (locking surface) m of the bulging portion 7 of the bottle mouth. May be formed. Further, as shown in FIG. 5 (C), the rising portion upper surface P may be formed on a protruding surface that protrudes upward.
更に、立ち上げ部上面 Pをボトル中心軸 Zに対し、 垂直となるよう構成 してもよい。  Further, the rising portion upper surface P may be configured to be perpendicular to the bottle center axis Z.
而して、 立ち上げ部 5の付根部分 9から先端部分 8まで、 横断面におい て、 全部がキャップ中央側に中心◦を持つ円弧となっている。 そして、 立 ち上げ部 5を横断面において円弧とすることにより、 横断面円弧状の部分 を持たない平板よりなる立ち上げ部に比べて強度を大にでき、座屈を防止 できる。 すなわち、 この発明では、 開栓時は、 あるいはキャップちょい回 しに対しては、立ち上げ部 5の平面視円弧状の上面 Pのほぼ全領域が膨出 部 7のリング状の下周面 （傾斜面） mにぴったりと強固に当接することに なる。 これにより、 立ち上げ部 5全体に均等に応力が分散されるため、 バ ンド部 4は、 開栓時、 あるいはキャップちょい回しに対して強固に瓶口 6 の膨出部 7の下周面 mをグリップでき、立ち上げ部 5が薄肉であるにもか かわらず、 かつ不連続であるにもかかわらず立ち上げ部 5の座屈を防止し ながら、瓶口 6へのグリップ性能を向上できる。 Thus, in the cross section, from the root portion 9 to the tip portion 8 of the rising portion 5, all are arcs having a center ◦ on the center side of the cap. Further, by forming the rising portion 5 as an arc in the cross section, the strength can be increased as compared with a rising portion formed of a flat plate having no arc-shaped portion in the cross section, and buckling can be prevented. That is, in the present invention, when the cap is opened, or when the cap is slightly turned, almost the entire area of the upper surface P of the rising portion 5 in the shape of a circular arc in plan view is formed on the lower peripheral surface of the bulging portion 7 (see FIG. (Slope surface) It comes into contact with m firmly and firmly. As a result, the stress is evenly distributed throughout the rising section 5, so that the band section 4 is firmly opened when the cap is opened or when the cap is slightly turned. The bulging part 7 of the bottle can be gripped by the lower peripheral surface m, and while the rising part 5 is thin, it is also discontinuous, while preventing buckling of the rising part 5, Grip performance to mouth 6 can be improved.
また、 立ち上げ部 5の付根部分 9を、 キャップ高さ方向に湾曲し、 かつ 、上側へ向けて T , 方向に凸状になるよう上に凸の湾曲部分 Sで構成して あるので、 立ち上げ部 5が内側に倒れる反転現象を確実に防止できる。 す なわち、 付根部分 9が薄肉であるにもかかわらず立ち上げ部 5の倒れを防 止しながら、瓶口へのグリップ性能を向上できる。  In addition, the root portion 9 of the rising portion 5 is formed by a curved portion S that is curved in the height direction of the cap and that is upwardly convex so as to be convex in the direction T and upward. It is possible to reliably prevent the inversion phenomenon in which the raising portion 5 falls down inward. In other words, it is possible to improve the grip performance on the bottle mouth while preventing the rising portion 5 from falling even though the base portion 9 is thin.
ところで、 比較例としての座屈を起こし易い薄肉で、 かつ、細長い平板 よりなる立ち上げ部では、 上述したように座屈は立ち上げ部の弱化部から はじまったり、 あるいは立ち上げ部のバンド部への付根部 （ヒンジ 部） からはじまる。 これは、立ち上げ部がこの発明の立ち上げ部 5のように横 断面円弧状ではなく、 立ち上げ部上面を瓶口の膨出部のリング状の下周面 (係止面） の円弧に沿わない平面視矩形状、 あるいは、平面視ほぼ台形形 状としていることと、 開栓時あるいはいたずらによるちよい回し時におい て、 立ち上げ部にかかる応力が分散されず、極端な場合膨出部のリング状 の下周面に一点で接触している立ち上げ部上面の中央に応力が集中して、 立ち上げ部は均等に力を分散して受けることができないことによる。 また 、比較例の場合、 この発明のようなキャップ高さ方向に湾曲し、 かつ、 上 側へ向けて凸状になるよう構成してある付根部分 9を持たないので、 開栓 時において付根部分が曲がり易く、 これにより、 立ち上げ部が内側に倒れ 易くなる。 よって、 比較例では、 付根部分から先端部分までの座屈が生じ るとともに、反転による （倒れることによる） 立ち上げ部の、瓶口の膨出 部の下周面 （係止面） からのすつぼ抜けが発生することになる。 このよう な問題点をこの発明は解決している。  By the way, as a comparative example, in the rising portion that is thin and easily formed and that is formed of an elongated flat plate, the buckling starts from the weakened portion of the rising portion, or to the band portion of the rising portion as described above. Begins at the base (hinge) of the. This is because the rising portion does not have an arc shape in cross section as in the rising portion 5 of the present invention, but the upper surface of the rising portion has an arc of a ring-shaped lower peripheral surface (locking surface) of the bulging portion of the bottle mouth. A rectangular shape or a trapezoidal shape in plan view that does not conform to the shape, and the stress applied to the rising portion is not dispersed when opening or turning it by mischief. This is because stress concentrates on the center of the upper surface of the rising portion that contacts the lower peripheral surface of the ring at one point, and the rising portion cannot receive the force evenly. Further, in the case of the comparative example, since the base portion 9 which is curved in the height direction of the cap as in the present invention and which is configured to be convex toward the upper side is not provided, the base portion at the time of opening the cap is opened. Is easy to bend, which makes it easy for the rising portion to fall inward. Therefore, in the comparative example, buckling occurs from the root portion to the tip portion, and the rising portion due to inversion (by falling down) is disengaged from the lower peripheral surface (locking surface) of the bulging portion of the bottle mouth. Potholes will occur. The present invention solves such a problem.
更に、 この発明では、 立ち上げ部 5の付根部分 9から先端部分 8まで、 横断面において、 全部がキャップ中央側に中心を持つ円弧となっているの で、 周方向に対する柔軟性を向上でき、 キャップ 1のねじ込みをスムース に行うことができる。 1 3は、立ち上げ部 5の裏の円弧面である。 Further, in the present invention, from the root portion 9 of the rising portion 5 to the tip portion 8, In the cross section, since all are arcs having a center on the center of the cap, flexibility in the circumferential direction can be improved, and the cap 1 can be screwed smoothly. 13 is an arc surface on the back of the rising portion 5.
また、 付根部分 9は上に凸の湾曲部分 Sで構成されているので、 バンド 部 4と立ち上げ部 5間に溜まったドレン、 例えば洗浄用の水滴、 あるいは 内容物のオーバーフローによる液は、 付根部分 9の前記上の円弧 9 a 〔第 2図 （B ) 参照〕 に沿って素早く立ち上げ部 5の裏側から、 バンド部 4お よび立ち上げ部 5間の隙間 Qを通って流れ落ちる。 そのため、 比較例のよ うな薄肉で、 かつ、細長い平板よりなる立ち上げ部の場合に比して、 バン ド部 4と立ち上げ部 5間に溜まったドレンを容易に素早く確実に排出でき る。  Further, since the root portion 9 is formed by the upwardly curved portion S, the drain collected between the band portion 4 and the rising portion 5, for example, a water drop for washing, or a liquid due to overflow of the content is removed from the root portion. Along the arc 9a above the part 9 [see FIG. 2 (B)], it quickly flows down from the back side of the rising part 5 through the gap Q between the band part 4 and the rising part 5. Therefore, the drain collected between the band portion 4 and the rising portion 5 can be discharged easily, quickly and surely, compared with the thin portion and the rising portion formed of an elongated flat plate as in the comparative example.
なお、 上記実施形態では、 第 2 図 （A) 、 第 6図 （A) に示すように、 平面視において立ち上げ部の付根部分 9の横断面形状が、外向きに突出し た円弧状であり、 かつ、 その曲率をキャップの中央を中心〇とする円弧 9 c , 9 dの曲率に設定したものを示したが、 この発明では、 前記円弧 9 c , 9 dの曲率より大きな曲率を持つ付根部分を備えた立ち上げ部を用いる の力好ましい。 すなわち、 横断面において、 キャップの中央を中心〇とす る第 6図 （A) に示したような円弧 9 c , 9 dを持つ付稂部分 9に比して 、 円弧 9 c , 9 dよりも湾曲度が大きな第 6図 （B ) に実線で示すような 円弧 4 5 a , 円弧 4 5 bを持つ付根部分 9を備えた立ち上げ部を用いるの が好ましい。 これにより、 立ち上げ部 5が内側に倒れる反転現象をより確 実に防止できる上に、立ち上げ部 5の強度を更に大にでき、 立ち上げ部を 薄肉で形成しても、 開栓時における立ち上げ部の座屈を確実に防止できる 第 7図および第 8図は、 バンド部 4から内向き上方向に連設した立ち上 In the above embodiment, as shown in FIGS. 2 (A) and 6 (A), the cross-sectional shape of the root portion 9 of the rising portion in a plan view is an outwardly protruding arc shape. Although the curvature is set to the curvature of the arcs 9c and 9d centered on the center of the cap, the present invention provides a root having a curvature larger than the curvatures of the arcs 9c and 9d. The use of a riser with a part is preferred. That is, in the cross section, as compared with the appendix 9 having the arcs 9 c and 9 d as shown in FIG. 6 (A) centered on the center of the cap, the arcs 9 c and 9 d Also, it is preferable to use a rising portion having a root portion 9 having a circular arc 45a and a circular arc 45b as shown by a solid line in FIG. 6 (B) having a large degree of curvature. As a result, it is possible to more reliably prevent the inversion phenomenon in which the rising portion 5 falls down inward, and further increase the strength of the rising portion 5. The buckling of the raised part can be reliably prevented.
