Description

この発明は、キャップ本体の下端にブリッジ部を介してバンド部を設けたピルファープルーフキャップに関するものである。   The present invention relates to a pilfer proof cap in which a band portion is provided at a lower end of a cap body via a bridge portion.

メカニカルに瓶口に係止するタイプのピルファープルーフキャップのバンド部は、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）からすっぽ抜けないよう、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）の引っ張り力がかかっ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 portion of the pilfer proof cap that is mechanically locked to the bottle mouth must be firmly gripped to the bottle mouth at the time of opening or against mischief. That is, at the time of opening, for example, a plurality of rising portions that are bent from the lower end of the band portion in a discontinuous state and are raised inward upwards from the bulging portion (bottleneck, bead) of the bottle mouth. The tip portions of the raised portions so that the bridge portions are surely broken by applying a tensile force in the vertical direction (vertical direction) to the plurality of bridge portions provided between the cap body and the band portion so as not to come off. Must be securely locked 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１５図（Ａ）に示すような矩形状、あるいは、第１５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４１，４２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４１，４２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。   For this purpose, from the root part to the tip part of the rising part, it has a rectangular shape as shown in FIG. 15 (A), or a substantially trapezoidal cross section as shown in FIG. 15 (B). In the rising portions 41 and 42 made of an elongated flat plate, buckling (a phenomenon in which bending is caused by sequential deformation in the lateral direction due to pressure applied in the vertical direction of the rising portion) is prevented, and the rising portions 41 and 42 are inward. The only way to prevent the falling reversal phenomenon is to increase the thicknesses a and b. This is because when the plurality of raised portions are thinned, the raised portions themselves buckle. The buckling starts from the weakened part of the rising part or starts from the root part (hinge part) of the rising part to the band part.

しかし、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根部（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）は薄肉になり易い。   However, the thickening of the start-up part becomes an obstacle when getting over the bottle skirt when tightening the cap around the bottle mouth (when closing the cap), making it difficult to fit the cap into the bottle mouth. Thickening is naturally limited, and extreme thickening cannot be achieved. Further, since the root portion (hinge portion) of the rising portion is provided in a very small space, and since the rising portion is bent from the root portion (hinge portion), the root portion (hinge portion) of the rising portion. 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）を容易にしてキャッピ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ャップを提供することである。   The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to facilitate capping performance by making it easy to attach (fit) to the bottle mouth when closing, and to improve the seating of the start-up part when opening. To provide a pill fur proof cap capable of improving the grip performance to the bottle mouth while preventing bending and / or falling.

上記目的を達成するために、この発明のピルファープルーフキャップは、キャップ本体の下端にブリッジ部を介してバンド部を設けたピルファープルーフキャップにおいて、前記バンド部から内向き上方向に立ち上げ部を連設し、この立ち上げ部の付根部分を、キャップ高さ方向に湾曲し、かつ、上側又は下側へ向けて凸状になるように構成してあることを特徴とする（請求項１）。 In order to achieve the above object, a pilfer-proof cap according to the present invention is a pilfer-proof cap in which a band portion is provided at a lower end of a cap body via a bridge portion, and a rising portion inwardly upward from the band portion. The root portion of the rising portion is curved in the cap height direction and is convex upward or downward (Claim 1). ).

また、上記ピルファープルーフキャップにおいて、前記立ち上げ部が横断面円弧状の部分を有していてもよく（請求項２）、この場合、さらに、前記立ち上げ部の前記バンド部への付根部分を横断面において円弧状とするとともに、前記立ち上げ部の先端部分を横断面において円弧状としてあってもよい（請求項３）。 In the pilfer-proof cap, the rising portion may have a circular arc-shaped portion (Claim 2). In this case, the root portion of the rising portion to the band portion is further included. May have an arc shape in the cross section, and a tip portion of the rising portion may have an arc shape in the cross section.

また、上記ピルファープルーフキャップにおいて、前記立ち上げ部が、横断面形状において、外向き凸状の部分および／または内向き凸状の部分を有していてもよい（請求項７）。 Further, in the pilfer proof cap, the rising portion may have an outwardly convex part and / or an inwardly convex part in a cross-sectional shape (claim 7).

また、上記ピルファープルーフキャップにおいて、前記立ち上げ部の付根部分の横断面形状が、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とする円弧の曲率より大としてあってもよい（請求項９）。 Further, in the pilfer-proof cap, the cross-sectional shape of the root portion of the rising portion is an arc shape protruding outward, and the curvature is larger than the curvature of the arc centered on the center of the cap. It may be a (claim 9).

請求項１では、立ち上げ部の付根部分を、キャップ高さ方向に湾曲し、かつ、上側又は下側へ向けて凸状になるように構成してあるので、立ち上げ部が内側に倒れる反転現象を確実に防止できる。
請求項２では、立ち上げ部が横断面円弧状の部分を有しているので、既存の平板よりなる立ち上げ部に比べて、強度が大であり、したがって、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防止できる。 In claim 1, since the root portion of the rising portion is configured to be curved in the cap height direction and convex toward the upper side or the lower side, the rising portion falls inward. The phenomenon can be reliably prevented.
In the second aspect, since the rising portion has an arc-shaped portion in cross section, the strength is higher than that of an existing flat plate rising portion. Therefore, the rising portion is formed thin. However, buckling of the rising portion at the time of opening can be prevented.

請求項３では、立ち上げ部のバンド部への付根部分を横断面において円弧状とするので、円弧状の付根部分を持たない既存の平板よりなる立ち上げ部に比べて、強度が大であり、したがって、付根部分を薄肉に形成しても、開栓時において付根部分を曲がり難くでき、これにより、立ち上げ部が内側に倒れないように付根部分の強度を大にでき、立ち上げ部の倒れを防止できる。更に、立ち上げ部の先端部分を横断面において円弧状としてあるので、付根部分から先端部分までの座屈と、瓶口の膨出部の係止面からの立ち上げ部のすっぽ抜けとを防止できる。 In claim 3, since the root portion of the rising portion to the band portion is formed in an arc shape in the cross section, the strength is higher than that of the rising portion made of an existing flat plate having no arc-shaped root portion. Therefore, even if the root portion is formed thin, it is difficult to bend the root portion at the time of opening, so that the strength of the root portion can be increased so that the rising portion does not fall inward. Can prevent falling. Furthermore, since the tip portion of the rising portion has an arc shape in the cross section, the buckling from the root portion to the tip portion and the slippage of the rising portion from the locking surface of the bulging portion of the bottle mouth Can be prevented.

請求項７のように構成した場合も前記した既存の平板よりなる立ち上げ部に比べて、強度が大であり、したがって、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防止できる。 Even when configured as in claim 7 , the strength is higher than that of the above-described rising portion made of an existing flat plate. Therefore, even if the rising portion is formed thin, the rising portion at the time of opening the plug Can be prevented from buckling.

請求項９記載のピルファープルーフキャップでは、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とする円弧の曲率より大としてあるので、つまり、横断面において、キャップの中央を中心Ｏとする図６（Ａ）に示すような円弧９ｃ，円弧９ｄを持つ付根部分９に比して、円弧９ｃ，円弧９ｄよりも湾曲度が大の円弧４５ａ，円弧４５ｂ〔第６図（Ｂ）参照〕を付根部分９が有することにより、立ち上げ部５の強度を更に大にでき、立ち上げ部５を薄肉で形成しても、開栓時における立ち上げ部５の座屈を確実に防止できる。 In the pilfer-proof cap according to claim 9, the cross-sectional shape of the root portion 9 of the rising portion is an arc shape projecting outward, and the curvature thereof is based on the curvature of the arc centered on the center of the cap. In other words, in comparison with the root portion 9 having the arc 9c and the arc 9d as shown in FIG. 6A with the center O at the center of the cap in the cross section, it is more than the arc 9c and the arc 9d. Since the root portion 9 has arcs 45a and 45b [see FIG. 6 (B)] having a large degree of curvature, the strength of the rising portion 5 can be further increased, and the rising portion 5 is formed thin. In addition, it is possible to reliably prevent buckling of the rising portion 5 at the time of opening.

第１図〜第４図は、バンド部から内向き上方向に連設した立ち上げ部を、バンド部の円周方向において不連続の状態で複数個設けるとともに、各立ち上げ部のバンド部への付根部分から先端部分まで、横断面において、全部がピルファープルーフ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するとともに、前記付根部分を、キャップ中心軸の方向（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に構成してあるこの発明の第１の実施形態を示す。   FIGS. 1 to 4 show that a plurality of rising portions connected inward and upward from the band portion are provided in a discontinuous state in the circumferential direction of the band portion, and to the band portion of each rising portion. In the cross section from the root part to the tip part of the pilfer proof cap, the entire part is formed into an arc having the center of the arc on the center side of the pilfer proof cap, and the root part is in the direction of the cap center axis (cap height direction) 1 shows a first embodiment of the present invention which is configured to be curved and convex upward.

第１図〜第４図において、１は、ピルファープルーフキャップで、キャップ本体２の下端に多数のブリッジ部３を介して環状のバンド部４が設けられている。５は、バンド部４の内面側で、且つ、円周方向において不連続の状態で複数個設けられた立ち上げ部である。各立ち上げ部５は、バンド部４から内向き上方向に連設されている。   1 to 4, reference numeral 1 denotes a pilfer-proof cap, and an annular band portion 4 is provided at the lower end of the cap body 2 via a large number of bridge portions 3. Reference numeral 5 denotes a plurality of rising portions provided on the inner surface side of the band portion 4 and in a discontinuous state in the circumferential direction. Each rising portion 5 is connected inward and upward from the band portion 4.

ボトル１’はピルファープルーフキャップ（以下、単にキャップという）１が取り付けられる（嵌込まれる）環状の瓶口６を有する一方、前記立ち上げ部５は、前記瓶口６に形成された環状の膨出部（ボトルネック，ビード）７の下周面（後述する）に係止する先端部分８を有する。   The bottle 1 ′ has an annular bottle opening 6 into which a pilfer proof cap (hereinafter simply referred to as a cap) 1 is attached (inserted), while the rising portion 5 is formed in an annular shape formed in the bottle opening 6. It has a front end portion 8 that engages with a lower peripheral surface (described later) of the bulging portion (bottleneck, bead) 7.

膨出部７は、リング状のテーパ面となっている下周面（係止面）ｍを有する。この下周面ｍは、瓶口６の径方向外側に上向きに傾斜している。   The bulging portion 7 has a lower peripheral surface (locking surface) m that is a ring-shaped tapered surface. The lower peripheral surface m is inclined upward outward in the radial direction of the bottle mouth 6.

そして、少なくとも環状の瓶口６の膨出部７の外周面とバンド部４の内周面Ｂとは同心円状に形成されている。すなわち、瓶口６にキャップ１が取り付けられた状態では、ボトル中心軸Ｚとキャップ中心軸Ｚ’とは同軸となる。更に、バンド部４の最小内径は膨出部７の最大外径以上に設定されている。   At least the outer peripheral surface of the bulging portion 7 of the annular bottle mouth 6 and the inner peripheral surface B of the band portion 4 are formed concentrically. That is, in the state where the cap 1 is attached to the bottle mouth 6, the bottle center axis Z and the cap center axis Z 'are coaxial. Further, the minimum inner diameter of the band portion 4 is set to be greater than or equal to the maximum outer diameter of the bulging portion 7.

９は、立ち上げ部５の前記バンド部４への付根部分（ヒンジ部分）である。この実施形態では、付根部分９は、バンド部４の内壁４ａからではなくバンド部４の下端に形成した裾１１から曲げられてなる。なお、付根部分９をバンド部４の内壁４ａから曲げて構成してもよい。   Reference numeral 9 denotes a root portion (hinge portion) of the rising portion 5 to the band portion 4. In this embodiment, the root portion 9 is bent not from the inner wall 4 a of the band portion 4 but from the skirt 11 formed at the lower end of the band portion 4. The root portion 9 may be bent from the inner wall 4 a 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。   The characteristic configuration of the present invention will be described below.

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Ｔ1 方向に凸状になるよう構成してある〔第３図参照〕。 As described above, a plurality of rising portions 5 that are continuously provided inward and upward from the band portion 4 are provided in a discontinuous state in the circumferential direction of the band portion 4. And from the root part 9 to the front-end | tip part 8 to the band part 4 of each raising part 5, all are comprised so that it may become a circular arc which has the center of a circular arc in the cap center side in the cross section. Further, the base portion 9, a circular arc curved in the cap height direction (the direction indicated by double-headed arrow T), and are configured so as to be convex T 1 direction towards the upper Third sloppy irradiation ].

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９ａ，９ｂ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１１から曲げられてキャップ高さ方向（Ｔ方向）の上側（Ｔ1 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、Ｔ1 方向に湾曲した上下の円弧９ａおよび９ｂ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 a circular cross-sectional shape and is formed in a shape in which a thin flat rectangular plate is curved so that the arc has the center of the arc on the cap center side, and the root portion 9 is on the upper side. It is formed to have arcs 9a, 9b that are convex toward the top. That is, the rising portion 5 has a shape in which a thin, rectangular flat plate is curved in a circular arc shape from the center side of the cap toward the outside, that is, an outwardly convex circular arc portion in the cross-sectional shape. As shown in FIG. 3, from the root portion 9 to the tip portion 8 of the rising portion 5, the entire cross section is an arc having a center on the center side of the cap. For example, the plan view or the cross-sectional shape of the root portion 9 is formed in an arc shape protruding outward as shown in FIG. 2 (B). In addition, the root portion 9 is formed of a convex curved portion S that is bent from a skirt 11 formed at the lower end of the band portion 4 and faces upward (T 1 direction) in the cap height direction (T direction). The upper and lower ends of the curved portion S of the convex upward, respectively, having upper and lower arc 9a Contact and 9b curved in T 1 direction. The root portion 9 is also 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７ａ，７ａ〔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８ａおよび８ａ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７ａを含む円とはキャップ中央側の中心Ｏ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Ｏとする円弧８ａ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 along arcs 7a and 7a (see FIG. 4A) 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 has an arcuate shape in plan view so that the upper surface P of the rising portion 5 is substantially in contact with the lower peripheral surface m at the initial stage of opening (cap opening). That is, as shown in FIG. 4 (A), an outer circle and an inner circle including the arcs 8a and 8a of the rising portion upper surface P, respectively, and a circle including the arc 7a constituting the lower peripheral surface m of the bulging portion 7 Is a concentric circle sharing the center O on the center side of the cap. As a result, almost the entire region of the rising portion upper surface P can be brought into tight contact with the lower peripheral surface m. In addition, the shape in plan view is an arc shape protruding outward, and its curvature is larger than the curvature of the arc 8a with the center O of the center of the cap as shown by a dotted line in FIG. Even if the raised portion upper surface P ′ has a shape, almost the entire region of the raised portion upper surface P ′ 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Ｔ1 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。 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 is shown in FIG. as also shown, it may if configured so as to be convex T 1 direction towards the upper side, the shape of the raised portion upper surface P may 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. In this case, only the tip 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). Further, as shown in FIG. 5 (B), a recessed surface that is recessed downward so that the upper surface P of the rising portion is in surface contact with the lower peripheral surface (locking surface) m of the bulging portion 7 of the bottle mouth. You may form in. Further, as shown in FIG. 5C, the rising portion upper surface P may be formed on a protruding surface protruding 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。   Furthermore, the rising portion upper surface P may be configured to be perpendicular to the bottle central 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Ｏ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, from the root portion 9 to the tip portion 8 of the rising portion 5, all of the cross section is an arc having a center O on the cap center side. And by making the rising part 5 into a circular arc in the cross section, the strength can be increased as compared with a rising part made of a flat plate having no arc-shaped part in the cross section, and buckling can be prevented. That is, according to the present invention, when the cap is opened or when the cap is swung, almost the entire region of the upper surface P in the arcuate shape of the rising portion 5 is the ring-shaped lower peripheral surface (inclined) of the bulging portion 7. Surface) abuts firmly and firmly on m. As a result, the stress is evenly distributed over the entire rising portion 5, so that the band portion 4 is firmly attached to the lower peripheral surface m of the bulging portion 7 of the bottle mouth 6 at the time of opening or turning the cap. The grip performance to the bottle mouth 6 can be improved while preventing the buckling of the rising portion 5 even though the rising portion 5 is thin and is discontinuous.

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Ｔ1 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。 Further, the base portion 9 of the raised portion 5, curved cap in the height direction, and, since the on so as to be convex T 1 direction towards the upper side are constituted with curved portion S of the convex, Standing The reversal phenomenon in which the raising portion 5 falls inward can be reliably prevented. That is, the grip performance to the bottle mouth can be improved while preventing the rising portion 5 from falling despite the thin root portion 9.

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ょい回し時において、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）からのすっぽ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 described above, in the rising portion made of a thin and thin flat plate as a comparative example, the buckling starts from the weakened portion of the rising portion or goes to the band portion of the rising portion as described above. starting from the root portion (Hin-shaped portion). This is because the rising portion is not in the shape of a circular arc as in the rising portion 5 of the present invention, but the upper surface of the rising portion is an arc of the ring-shaped lower peripheral surface (locking surface) of the bulging portion of the bottle mouth. It has a rectangular shape in plan view that does not follow, or a substantially trapezoidal shape in plan view, and the stress applied to the rising part is not dispersed during opening or when tampering with mischief. This is because stress concentrates at the center of the upper surface of the rising portion that is in contact with the lower peripheral surface 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 is curved in the cap height direction as in the present invention and does not have the root portion 9 configured to be convex upward, the root portion is not opened when the cap is opened. It is easy to bend, and this 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 tail of the rising portion due to inversion (by falling) from the lower peripheral surface (locking surface) of the bulging portion of the bottle mouth Missing will occur. The present invention solves such problems.

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。１３は、立ち上げ部５の裏の円弧面である。   Further, in the present invention, since all of the cross section from the root portion 9 to the tip portion 8 of the rising portion 5 is an arc having a center on the center side of the cap, the flexibility in the circumferential direction can be improved, and the cap 1 screwing can be performed smoothly. Reference numeral 13 denotes 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９ａ〔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 composed of an upwardly curved portion S, drainage accumulated between the band portion 4 and the rising portion 5, for example, water droplets for washing or overflowing contents, is Along the upper arc 9a [see FIG. 2 (B)] of the portion 9, it quickly flows down from the back side of the rising portion 5 through the gap Q between the band portion 4 and the rising portion 5. Therefore, the drain accumulated between the band part 4 and the rising part 5 can be easily and quickly discharged as compared with the case where the rising part is made of a thin and thin flat plate as in the comparative example.

なお、上記実施形態では、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Ｏとする円弧９ｃ，９ｄ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９ｃ，９ｄ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が好ましい。すなわち、横断面において、キャップの中央を中心Ｏとする第６図（Ａ）に示したような円弧９ｃ，９ｄを持つ付根部分９に比して、円弧９ｃ，９ｄ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４５ａ，円弧４５ｂ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。 In the above embodiment, as shown in FIG. 6 (A), the cross-sectional shape of the root portion 9 of the raised portion in a plan view, a circular arc shape protruding outward, and a cap of curvature The curvature of arcs 9c and 9d with the center O as the center is shown. However, in the present invention, a rising portion having a root portion having a curvature larger than the curvature of the arcs 9c and 9d is used. preferable. That is, in the cross section, the degree of curvature is larger than that of the arcs 9c and 9d as compared with the root portion 9 having the arcs 9c and 9d as shown in FIG. It is preferable to use a rising portion having a root portion 9 having an arc 45a and an arc 45b as shown by solid lines in FIG. 6 (B). As a result, the reversal phenomenon that the rising portion 5 falls inward can be prevented more reliably, and the strength of the rising portion 5 can be further increased. The buckling of the raised portion can be reliably prevented.

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げ部５’，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、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するとともに、付根部分９を、バンド部４の下端に形成した裾１１から曲げられてキャップ高さ方向（Ｔ方向）の上側（Ｔ1 方向）へ向く凸状の湾曲部分Ｓで構成し、更に、前記立ち上げ部５’，５’’の付根部分９から先端部分８まで、前記立ち上げ部５’，５’’における前記バンド部４の円周方向に沿う幅が変化するよう、それぞれ、構成してあるこの発明の第２の実施形態およびこの発明の第３の実施形態を示す。なお、第７図および第８図において、第１図および第４図に示した符号と同一のものは同一または相当物である。 7 and FIG. 8 are provided with a plurality of raised portions 5 ′, 5 ″ provided in a continuous inward direction from the band portion 4 in a discontinuous state in the circumferential direction of the band portion 4.

第７図において、立ち上げ部５’は、付根部分９から先端部分８にいくにつれ先細り形状に形成されている。この場合でも、上記第１の実施形態で示した立ち上げ部５と同様の効果を奏する。すなわち、この実施形態でも、開栓時には立ち上げ部５’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とともに、閉栓時には瓶口への取り付け（嵌まり込み）を容易にしてキャッピング性能を向上できるピルファープルーフキャップ１を提供することができる。   In FIG. 7, the rising portion 5 ′ is formed in a tapered shape as it goes from the root portion 9 to the tip portion 8.

第９図において、ピルファープルーフキャップ１には、キャップ本体２の下端に多数のブリッジ部３を介して環状のバンド部４が設けられている。   In FIG. 9, the pilfer proof cap 1 is provided with an annular band portion 4 via a large number of bridge portions 3 at the lower end of the cap body 2.

１００は、バンド部４の円周方向において連続の状態で全周にわたり設けた立ち上げ部である。立ち上げ部１００は、バンド部下端から折曲して内向き上方向に立ち上げたもので、ほぼ蛇腹形状または多数の花弁形状をなす。この立ち上げ部１００は、上記第１の実施形態で示した立ち上げ部５と同一構成の立ち上げ部５０を複数個バンド部４の内面で、円周方向の全周にわたり連設してなる。立ち上げ部１００は、瓶口６に形成された環状の膨出部（ボトルネック，ビード）７の下周面ｍに係止する先端部分８０を有する。   Reference numeral 100 denotes a rising portion provided over the entire circumference in a continuous state in the circumferential direction of the band portion 4. The rising portion 100 is bent from the lower end of the band portion and is raised upward inward, and has a substantially bellows shape or a number of petal shapes.

そして、この発明では立ち上げ部は、バンド部の円周方向において連続または不連続の状態で設けられる。すなわち、第１１図に示すように、例えば第１０図（Ａ）の横断面において弓型形状をなす複数個の立ち上げ部５１をバンド部の円周方向において全周または一部にわたり連続させてもこのように、複数個の立ち上げ部５１を連続させると座屈防止強度のアップに繋がる。同様に第１０図（Ｂ）〜第１０図（Ｄ）に示すような横断面形状を持つ立ち上げ部５２，５４も全周にわたり連続させてもよく、また、一部を連続させてもよい。   In the present invention, the rising portion is provided in a continuous or discontinuous state in the circumferential direction of the band portion. That is, as shown in FIG. 11, for example, a plurality of raised portions 51 having an arcuate shape in the cross section of FIG. 10 (A) are continuously provided over the entire circumference or a part in the circumferential direction of the band portion. In this way, if the plurality of rising portions 51 are made continuous, the buckling prevention strength is increased. Similarly, the rising portions 52 and 54 having a cross-sectional shape as shown in FIGS. 10 (B) to 10 (D) may be continuous over the entire circumference, or a part thereof may be continuous. .

なお、上記各実施形態では、立ち上げ部５の付根部分９として、キャップ高さ方向（Ｔ方向）に湾曲し、かつ、上側へ向けてＴ1 方向に凸状になるよう構成したものを示したが、この発明では、第１２図に示すようなＴ方向に湾曲し、かつ、Ｔ1 方向と反対の下側へ向けて凸状になるよう構成した付根部分９を有する立ち上げ部５を用いてもよい。この場合も立ち上げ部の倒れを確実に防止できる。更に、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Ｏとする円弧９ｃ，９ｄの曲率より大としてある第６図（Ｂ）に実線で示したような付根部分９を用いるのが立ち上げ部５の座屈防止の点で好ましい。 In each of the above embodiments, the root portion 9 of the rising portion 5 is configured to be curved in the cap height direction (T direction) and convex upward in the T 1 direction toward the upper side. However, in the present invention, the rising portion 5 having the root portion 9 which is curved in the T direction as shown in FIG. 12 and is convex toward the lower side opposite to the T 1 direction is provided. It may be used. Also in this case, it is possible to reliably prevent the riser from falling down. Furthermore, the cross-sectional shape is an arc shape projecting outward, and the curvature is larger than the curvature of the arcs 9c and 9d with the center O of the cap as the center O, as shown by a solid line in FIG.
