Description

本発明は、ボトル等の容器口部に金属製キャップを巻締する際に、キャップ頂部の角部に加圧成形により形成された環状の絞り段差部の絞り深さを測定するキャップの絞り深さゲージ及びその測定方法に関する。   The present invention relates to a cap squeezing depth for measuring a squeezing depth of an annular squeeze step formed by pressure molding at a corner of a cap top when a metal cap is wound around a container mouth of a bottle or the like. It is related with a thickness gauge and its measuring method.

ボトルの容器口部に形成されたネジへの金属製キャップの巻締密封は、通常アルミニウム薄板で形成され、天面内面にライナー材を備えたネジ未加工のシェルを容器口部に巻締成形することにより行なっている。その際、キャップの密封性を確保するために、巻締装置のプレッシャーブロックにより天壁からスカート壁に通じる角部を絞り成形して角部に環状の絞り段差部を形成して、キャップシェル天壁内面に嵌装されたライナー材をボトルの口部端面に圧接させている。絞り段差部の絞り深さが不充分であると、ライナーとボトル口部端面との密着が不足し、密封不良となる。そのため、このような容器への充填密封ラインにおいては、サンプリング検査により、巻締されたキャップの絞り段差部の絞り深さの測定を行なって、品質管理を行なっている。従来、その絞り深さの測定は、図６に示すようなアダプタ２６付きのダイヤルゲージ２５を使用して手作業により行なっており、ダイヤルゲージ２５を片手で持ち、他方の手で測定物であるキャップが巻締されたボトル２９を把持して、キャップ３０の天面３１にアダプタ２６の底面を当て、測定子２７を直接キャップの絞り段差部３２に当てることにより、絞り段差部３２の深さを測定している（特許文献１の図９参照）。   The metal cap is tightly sealed to the screw formed at the bottle mouth of the bottle, and is usually formed of a thin aluminum plate, and the unthreaded shell with liner material on the inner surface of the top surface is wound onto the container mouth. It is done by doing. At that time, in order to secure the sealing performance of the cap, the corner portion leading from the top wall to the skirt wall is drawn by a pressure block of the winding device to form an annular throttle step portion at the corner portion, and the cap shell ceiling A liner material fitted on the inner surface of the wall is pressed against the end face of the mouth of the bottle. If the aperture depth of the aperture step portion is insufficient, the adhesion between the liner and the bottle mouth end surface is insufficient, resulting in poor sealing. Therefore, in such a filling and sealing line for the container, quality control is performed by measuring the drawing depth of the drawn stepped portion of the wound cap by sampling inspection. Conventionally, the measurement of the drawing depth is performed manually using a dial gauge 25 with an adapter 26 as shown in FIG. 6, and the dial gauge 25 is held with one hand and the other hand is the object to be measured. By grasping the bottle 29 around which the cap is wound, the bottom surface of the adapter 26 is applied to the top surface 31 of the cap 30, and the measuring element 27 is directly applied to the aperture step 32 of the cap. (Refer to FIG. 9 of Patent Document 1).

しかしながら、その場合、ダイヤルゲージも被測定物である容器も所定位置に固定されてなく、手で把持しているため、測定ブレや測定子の接触角度が一定せずに測定誤差が発生し易く、且つ測定精度に測定者の熟練度による個人差が大きいという問題点がある。そのため、前記特許文献１では、金属製のＰＰキャップで巻締密封した飲料ボトルの絞り深さの寸法測定を、手作業による測定を廃して自動的に測定できるようにした飲料ボトル製品の自動検査装置を提案している。特に、本願図５に示すような近年の薄肉ボトル缶用キャップ３５の場合、絞り荷重の低減による絞り深さの減少から、絞り段差部３７を特定することが困難となってきており、ダイヤルゲージを用いた手動による絞り段差部の正確な測定は困難な状況となっている。   However, in that case, the dial gauge and the container to be measured are not fixed in place and are held by hand, so that the measurement blur and the contact angle of the probe are not constant, and measurement errors are likely to occur. In addition, there is a problem that there is a large individual difference in measurement accuracy depending on the skill level of the measurer. Therefore, in the above-mentioned patent document 1, automatic inspection of beverage bottle products in which squeezing depth dimension measurement of a beverage bottle that is wound and sealed with a metal PP cap can be automatically measured without using manual measurement. A device is proposed. In particular, in the case of the cap 35 for a thin wall can as shown in FIG. 5 of the present application, it is difficult to specify the stepped portion 37 due to the reduction of the drawing depth due to the reduction of the drawing load. It is difficult to accurately measure the stepped portion of the aperture manually using the.

前記提案の自動検査装置は、コンベヤで搬送中の飲料ボトルを検査ステージに導入コンベヤで供給して、検査ステージに設置された昇降移動するターンテーブル上にボトルを１本づつ載せ、レーザー光路と直交するように移動させ、キャップの周面上の２箇所に予め設定した測定点を、レーザー寸法測定器により、非接触式に寸法を連続式に検出して、検出値とキャップの移動量とを演算処理することにより、キャップの絞り込み段差部の深さ（絞り深さ）を測定するものである。
しかしながら、このような自動検査装置は高価であり、且つ任意の測定場所に移動する等の自在な取り扱いができず、簡易な抜き取り検査には適してないなどの問題点がある。
特開平１０−３８５２７号公報 In the proposed automatic inspection apparatus, the beverage bottles being conveyed by the conveyor are supplied to the inspection stage by the introduction conveyor, and the bottles are placed one by one on the turntable installed on the inspection stage and orthogonal to the laser beam path. The measurement points set in advance at two locations on the peripheral surface of the cap are continuously detected in a non-contact manner with a laser dimension measuring device, and the detected value and the amount of movement of the cap are obtained. By performing arithmetic processing, the depth (throttle depth) of the narrowing step portion of the cap is measured.
However, such an automatic inspection apparatus is expensive and cannot be freely handled such as being moved to an arbitrary measurement place, so that it is not suitable for simple sampling inspection.
Japanese Patent Laid-Open No. 10-38527

前記のように容器に巻締されたキャップの絞り深さを光学的に自動的に測定できる装置は従来種々提供されているが、簡易に且つ測定者の個人差による測定値のバラツキが少なく、精度良く測定でき、しかも自在に持ち運びできる簡易で安価な満足のいく測定装置は未だ提供されてない。また、ダイヤルゲージで被測定物を正確に測定するには、ボトルの形状や寸法に対応してゲージの零点設定を正確に設定しなければならないが、従来の装置ではボトルに対応して簡単に且つ正確に零点設定を行なうのが困難であった。   Various devices that can optically and automatically measure the drawing depth of the cap wound on the container as described above have been provided in the past, but there are few variations in measurement values due to individual differences of the measurer, A simple, inexpensive and satisfactory measuring device that can be measured with high accuracy and can be freely carried has yet to be provided. In addition, in order to accurately measure an object to be measured with a dial gauge, the zero point setting of the gauge must be set accurately according to the shape and dimensions of the bottle. Moreover, it is difficult to set the zero point accurately.

本発明は、上記実情に鑑み創案されたものであって、ボトルへの充填密封ラインでの金属キャップの巻締密封検査のための抜き取り検査等において、キャップの絞り深さを簡易に測定でき、且つ測定者の個人差による測定値のバラツキが少なく、精度良く測定でき、しかも比較的安価であり、取り扱いが容易であるキャップの絞り深さ測定ゲージ、及びその測定方法を提供することを目的とする。   The present invention was devised in view of the above circumstances, and can easily measure the squeezing depth of a cap in a sampling inspection for a winding and sealing inspection of a metal cap in a filling and sealing line to a bottle, An object of the present invention is to provide a cap squeezing depth measurement gauge that can be measured with high accuracy, with little variation in measurement values due to individual differences among measurers, and relatively easy to handle, and a measuring method thereof. To do.

上記課題を解決する本発明に係るキャップ絞り深さゲージは、金属キャップの容器への巻締成形後のキャップ絞り深さを測定する絞り深さゲージであって、ダイヤルゲージ本体、該ダイヤルゲージ本体を保持するゲージホルダ、該ゲージホルダと一体になったアダプタとからなり、該アダプタはキャップシーリング時に用いるプレッシャーブロックの絞り成形型部分と同じ形状の段差部を有していることを特徴とするものである。   A cap drawing depth gauge according to the present invention for solving the above-mentioned problems is a drawing depth gauge for measuring a cap drawing depth after a metal cap is wound on a container, and comprises a dial gauge body and the dial gauge body. A gauge holder for holding the adapter, and an adapter integrated with the gauge holder, wherein the adapter has a step portion having the same shape as the drawing mold portion of the pressure block used during cap sealing. It is.

前記アダプタは、円筒壁部と天壁部を有し、前記円筒壁部の内周面に前記プレッシャーブロックの絞り成形型部に相当する段差部を有し、該段差部から下方の円筒壁内径が測定するキャップのスカート壁上部外径と略等しく形成され、且つ前記天壁部に測定子がキャップ天面基準面に当接できる位置に測定子出入穴が形成されている構成を採用することができる。被測定キャップのローレット部外径と同一寸法の外径を有し頂面に平坦面なゼロ点基準面を有する円柱状のゼロ点校正用ゲージとを組み合わせることによって、ゼロ点設定が容易且つ正確にできる。   The adapter has a cylindrical wall portion and a ceiling wall portion, and has a step portion corresponding to a drawing mold portion of the pressure block on an inner peripheral surface of the cylindrical wall portion, and an inner diameter of the cylindrical wall below the step portion. Adopting a configuration in which a measuring element entrance / exit hole is formed at a position where the measuring element can abut against the top surface of the cap top surface in the top wall portion. Can do. The zero point setting is easy and accurate by combining with a cylindrical zero point calibration gauge that has the same outer diameter as the knurled outer diameter of the cap to be measured and a flat zero point reference surface on the top surface. Can be.

また、本発明のキャップの絞り深さ測定方法は、金属キャップを容器に巻締成形後のキャップ絞り深さをダイヤルゲージにより測定する絞り深さ測定方法であって、絞り深さ測定時に、キャップシーリング時に用いるプレッシャーブロックの絞り成形型部分と同じ形状の段差部を有しているアダプタをキャップの絞り段差部に当て、且つ測定子がキャップ天面基準面に当るようにし、前記測定子のキャップ天面基準面からの変位量をダイヤルゲージで検知することにより絞り深さを測定するようにしたことを特徴とするものである。絞り深さ測定に先立ち、前記アダプタの絞り段差部がゼロ点校正用ゲージの頂部角部に当るように前記ダイヤルゲージを載せ、測定子がゼロ点基準面に当接した状態でゼロ点設定を行なうことによって、容易に且つ正確に零点設定を行なうことが出来る。   The method for measuring the depth of drawing of a cap according to the present invention is a drawing depth measuring method for measuring a cap drawing depth after a metal cap is wound around a container with a dial gauge. Apply the adapter having the same step as the drawing mold part of the pressure block used for sealing to the throttle step part of the cap and make the probe contact the top surface of the cap. The diaphragm depth is measured by detecting the amount of displacement from the top reference plane with a dial gauge. Prior to the aperture depth measurement, place the dial gauge so that the aperture step of the adapter contacts the top corner of the zero point calibration gauge, and set the zero point with the probe in contact with the zero point reference surface. By doing so, the zero point can be set easily and accurately.

請求項１〜請求項６の本発明によれば、ダイヤルゲージの測定子を直接絞り段差部に当ててキャップの絞り深さを測定するのでなく、プレッシャーブロックの絞り成形部分と同じ形状の筒状のアダプタを絞り段差部に当てて測定するので、絞り深さゲージが傾くことなく、熟練を要することなく簡単に且つ正確に精度良く測定することができる。また、従来のダイヤルゲージでは測定が困難であった絞り段差をほとんど特定できないような浅い絞り深さであっても、手動により正確に測定することが可能となる。   According to the first to sixth aspects of the present invention, instead of measuring the drawing depth of the cap by directly contacting the dial gauge probe to the drawing step portion, a cylindrical shape having the same shape as the drawing portion of the pressure block. Therefore, the diaphragm depth gauge is not tilted and measurement can be performed easily and accurately with high accuracy without requiring skill. Further, it is possible to manually measure accurately even with a shallow aperture depth that makes it difficult to specify the aperture step, which was difficult to measure with a conventional dial gauge.

また、ゲージホルダを請求項２のように構成することによって、ダイヤルゲージの測定子を被測定物の測定面に対して容易に直角に設定することができ、且つゲージの零点設定が容易にできる。そして、請求項３及び請求項５の構成によれば、ゼロ点校正ゲージを使用して零点設定を行なうことによって容易に且つ正確に零点設定を行なうことが出来、正確に被測定物の絞り段差部の深さを測定することができる。そして、１度ゼロ点校正を行えば、同一種類のキャップの絞り深さの測定には、以後はその都度ゼロ点設定を行なうことなく、アダプタを絞り段差部に押し当てるだけで、正確に測定することができ、測定効率を向上させることができる。   Further, by configuring the gauge holder as in claim 2, the dial gauge probe can be easily set at a right angle to the measurement surface of the object to be measured, and the zero point of the gauge can be easily set. . According to the configuration of claim 3 and claim 5, the zero point can be set easily and accurately by using the zero point calibration gauge, and the diaphragm step of the object to be measured can be accurately set. The depth of the part can be measured. Once the zero point calibration is performed, it is possible to accurately measure the aperture depth of the same type of cap by simply pressing the adapter against the aperture step without setting the zero point each time. Measurement efficiency can be improved.

以下、本発明の実施形態を図面を基に詳細に説明する。
図１〜図３は本発明に係る絞り深さ測定装置の実施形態を示し、図１はその一部破断正面図、図２は絞り段差部の深さを測定している状態の断面図、図３は測定前のキャリブレーション時の断面図を示している。本実施形態の絞り深さゲージ１は、ゲージ本体２、ゲージホルダ３及びアダプタ４から構成されている。ゲージ本体２は、ダイヤル目盛盤５、ステム６、測定子７を有する公知のダイヤルゲージが採用できる。ゲージホルダ３は、前記ゲージ本体１のステム６を嵌合固定し、且つ測定子７が貫通して下方に突出できるような嵌合穴８を有し、下端にアダプタ４が一体に固定されている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 3 show an embodiment of a drawing depth measuring device according to the present invention, FIG. 1 is a partially broken front view thereof, and FIG. 2 is a sectional view of a state in which the depth of a drawing step portion is measured, FIG. 3 shows a cross-sectional view during calibration before measurement. The drawing depth gauge 1 of the present embodiment includes a gauge body 2, a gauge holder 3, and an adapter 4. As the gauge body 2, a known dial gauge having a dial scale plate 5, a stem 6 and a measuring element 7 can be adopted. The gauge holder 3 has a fitting hole 8 through which the stem 6 of the gauge main body 1 is fitted and fixed, and the probe 7 can pass through and protrude downward. The adapter 4 is integrally fixed at the lower end. Yes.

アダプタ４は、本実施形態では図１に示すように、ゲージホルダ３と一体の金属材料で形成されているが、別途に形成して一体に固定してもよい。アダプタ４は、絞り段差部を形成するキャップ巻締装置のプレッシャーブロックと同様な形状及び寸法で形成され、円筒壁部１２と天壁部１３を有し、円筒壁１２の内周面に前記プレッシャーブロックの絞り成形型部に相当する段差部１４を有し、該段差部から下方の円筒壁内周面１６の内径が被測定キャップのスカート壁上部（この部分にはローレットが形成されている場合が多い）外径と略等しく形成されている。そして、天壁部１３に測定子７が通過する測定子出入穴１７が形成されている。測定子出入穴１７の位置は、測定時に測定子７がキャップ天面基準面に当接する位置であればよく、図２に示すようにボトル口頂部の真上に位置する環状のキャップ天面平坦部３８をキャップ天面基準面とするのが望ましく、そこに測定子が当接するように形成するのが望ましいが、キャップ天面が一様な平面であれば、天面中央部であってもよく、特にその位置は限定されない。なお、１８は、測定子出入穴１７近傍の円筒壁部１２に形成された監視穴であり、ゼロ点設定時および測定時に測定子７の当接位置を確認できるようになっている。   In this embodiment, the adapter 4 is formed of a metal material that is integral with the gauge holder 3, as shown in FIG. 1, but may be separately formed and fixed integrally. The adapter 4 is formed in the same shape and size as the pressure block of the cap winding device that forms the throttle step portion, and has a cylindrical wall portion 12 and a top wall portion 13, and the pressure is applied to the inner peripheral surface of the cylindrical wall 12. It has a step 14 corresponding to the drawing mold part of the block, and the inner diameter of the inner peripheral surface 16 of the cylindrical wall below the step is the upper part of the skirt wall of the cap to be measured. It is formed approximately equal to the outer diameter. A measuring element entrance / exit hole 17 through which the measuring element 7 passes is formed in the top wall portion 13. The position of the probe access hole 17 may be any position where the probe 7 abuts the cap top surface reference surface at the time of measurement. As shown in FIG. 2, the annular cap top surface is flat just above the bottle top. It is desirable that the portion 38 be a cap top surface reference surface, and it should be formed so that the probe contacts the surface. However, if the cap top surface is a uniform plane, Well, the position is not particularly limited. Reference numeral 18 denotes a monitoring hole formed in the cylindrical wall portion 12 in the vicinity of the probe access hole 17 so that the contact position of the probe 7 can be confirmed at the time of zero point setting and measurement.

本実施形態の絞り深さゲージは、付属部品としてゼロ点校正用ゲージを備え、測定開始に先だって該ゼロ点校正用ゲージを使用することによって、簡単にゼロ点校正ができるようになっている。ゼロ点校正用ゲージ２０は図３に示すように、円柱状を呈し、その周壁２１の外径がキャップのスカート壁上部外径と略等しく、その頂面２２が平坦面に形成されている。したがって、アダプタ４の段差部１４下方の円筒壁内周面１６が、ゼロ点校正用ゲージ２０の周壁２１に嵌合し、段差部１４がその頂部角部に係合し、ゼロ点校正を行うことができるようになっている。   The aperture depth gauge of the present embodiment includes a zero point calibration gauge as an accessory, and the zero point calibration can be easily performed by using the zero point calibration gauge prior to the start of measurement. As shown in FIG. 3, the zero point calibration gauge 20 has a cylindrical shape, the outer diameter of the peripheral wall 21 is substantially equal to the outer diameter of the upper part of the skirt wall of the cap, and the top surface 22 is formed as a flat surface. Accordingly, the cylindrical wall inner peripheral surface 16 below the step portion 14 of the adapter 4 is fitted to the peripheral wall 21 of the zero point calibration gauge 20, and the step portion 14 is engaged with the top corner portion to perform zero point calibration. Be able to.

本実施形態に係る絞り深さゲージは、以上のように構成され、キャップ巻締容器のキャップ絞り深さ測定に先立ってダイヤルゲージの零点設定をゼロ点校正ゲージ２０により次のように行なう。
絞り深さゲージ１のアダプタ４を図３に示すようにゼロ点校正用ゲージ２０の頂部に嵌合すると、アダプタ４の段差部１４がゼロ点校正用ゲージ２０の頂面外周部に係合し、アダプタ円筒壁内周面１６が周壁２１と嵌合するので、傾くことなく安定してダイヤルゲージをゼロ点校正用ゲージ２０に垂直に当てることができる。その際、測定子７の先端は図１に示すように段差部１４の位置より下方に突出している状態から、ゼロ点校正用ゲージ２０の頂面に当って押し込まれ、その先端が段差部１４と同じレベル位置でゼロ点校正用ゲージ２０の頂面に当接した状態となる。したがって、その点を基準にしてダイヤルゲージのゼロ点設定を行なうことができる。 The drawing depth gauge according to the present embodiment is configured as described above, and the zero point of the dial gauge is set by the zero point calibration gauge 20 as follows prior to the measurement of the cap drawing depth of the cap winding container.
When the adapter 4 of the aperture depth gauge 1 is fitted to the top of the zero point calibration gauge 20 as shown in FIG. 3, the stepped portion 14 of the adapter 4 is engaged with the outer peripheral portion of the top surface of the zero point calibration gauge 20. Since the adapter cylindrical wall inner peripheral surface 16 is fitted with the peripheral wall 21, the dial gauge can be stably applied perpendicularly to the zero point calibration gauge 20 without being inclined. At that time, the tip of the measuring element 7 is pushed in from the state where it protrudes downward from the position of the stepped portion 14 as shown in FIG. Is in contact with the top surface of the zero point calibration gauge 20 at the same level position. Therefore, the zero point of the dial gauge can be set based on that point.

以上のようにしてゼロ点設定を終了した絞り深さゲージを使用して、例えば、図５に容器４０に巻締されたキャップ３５の絞り段差部３７の絞り深さｓを測定するには、図２に示すように、ダイヤルゲージのゲージホルダ３を把持して容器のキャップ天面に、真上から押し当てることにより、ゲージホルダ３の円筒壁内周面がキャップのスカート壁上部３９に形成されたローレット部の外周に嵌合し、その段差面１４がキャップの絞り段差部３７に突き当たる。この状態で測定子の先端はキャップのキャップ天面基準面である天面平坦部３８に当っている。したがって、そのときの測定子のゼロ点設定値からの変位量が絞り成形部の絞り深さとなり、ダイヤルゲージの目盛を読み取ることによって、絞り深さを測定することができ、合格基準値内にあるか否かすぐに判別できる。   For example, in order to measure the drawing depth s of the drawing step portion 37 of the cap 35 wound around the container 40 in FIG. 5 using the drawing depth gauge after the zero point setting is completed as described above, As shown in FIG. 2, the inner peripheral surface of the cylindrical wall of the gauge holder 3 is formed on the upper part 39 of the skirt wall of the cap by grasping the gauge holder 3 of the dial gauge and pressing it against the top of the cap of the container from directly above. The stepped surface 14 abuts against the throttle stepped portion 37 of the cap. In this state, the tip of the probe contacts the top flat portion 38 which is the cap top reference plane of the cap. Therefore, the amount of displacement from the zero point setting value of the probe at that time becomes the drawing depth of the drawn part, and the drawing depth can be measured by reading the scale of the dial gauge. It can be immediately determined whether or not there is.

以上のように、本発明の絞り深さゲージによれば、従来の絞り深さゲージと同様、手持ちで絞り深さを測定するものであるが、直接測定子をキャップの絞り段差部に当てて絞り深さを測定するのでなく、プレッシャーブロックの絞り成形部と同じ形状の筒状のアダプタを絞り段差部に当てて測定するので、絞り深さゲージが傾くことなく、熟練を要することなく簡単に且つ正確に測定することができる。   As described above, according to the diaphragm depth gauge of the present invention, the diaphragm depth is measured by hand as in the case of the conventional diaphragm depth gauge, but the probe is directly applied to the diaphragm step portion of the cap. Rather than measuring the drawing depth, the cylindrical adapter with the same shape as the drawing part of the pressure block is applied to the drawing step part, so the drawing depth gauge does not tilt and it does not require skill. And it can measure accurately.

図４は、本発明に係るキャップの絞り深さゲージの他の実施形態であり、前記実施形態と同様な部分は同一符号を付し、相違点のみ説明する。上記実施形態の絞り深さゲージは、特定のキャップ外径、絞り深さを有するキャップ専用に形成されているが、キャップの巻締の場合、絞り深さは一定であるが、容器への充填条件や容器の材質等によってスカート壁上部外径を若干変更して巻締する場合がある。そのような場合、前記実施形態では、円筒壁内周面の内径の相違するアダプタを有する絞りゲージを用意しなければならないが、本実施形態では、キャップのスカート壁上部に嵌合する部分を交換可能な別部材にすることによって、１台の装置で対応できるようにしたものである。すなわち、本実施形態では、アダプタ４を絞り成形型部２３とキャップスカート壁上部嵌合部２４に分割し、キャップスカート壁上部嵌合部２４は、絞り成形型部の円筒壁部に適宜手段で着脱自在に取付けてある。キャップスカート壁上部嵌合部２４は、スカート壁上部と嵌合する部分がスカート壁上部外径と同じ内径を有するリング状に形成されている。したがって、絞り成形型部２３にキャップスカート壁上部嵌合部２４を取り付けた状態で、絞り成形型部２３の下端面とキャップスカート壁上部嵌合部２４との間に段差ができ、絞り成形型を構成する。キャップスカート壁上部嵌合部２４は、キャップのスカート壁上部外径に応じて複数内径のものを用意し、スカート壁上部径が相違するキャップの絞り深さを測定する場合、交換することによって、１台の絞り深さゲージで測定することができる。また、それに伴って、キャップスカート壁上部嵌合部の外径に対応するゼロ点校正用ゲージも用意する必要がある。   FIG. 4 shows another embodiment of the cap depth gauge according to the present invention. The same parts as those in the above embodiment are given the same reference numerals, and only different points will be described. The drawing depth gauge of the above embodiment is formed exclusively for a cap having a specific cap outer diameter and drawing depth, but when the cap is tightened, the drawing depth is constant, but the container is filled. Depending on the conditions and the material of the container, the outer diameter of the upper part of the skirt wall may be slightly changed and tightened. In such a case, in the above-described embodiment, it is necessary to prepare a restriction gauge having an adapter having an inner diameter different from that of the inner peripheral surface of the cylindrical wall. By making it a possible separate member, it can be handled by a single device. That is, in this embodiment, the adapter 4 is divided into the drawing mold part 23 and the cap skirt wall upper fitting part 24, and the cap skirt wall upper fitting part 24 is appropriately attached to the cylindrical wall part of the drawing mold part. It is attached detachably. The cap skirt wall upper fitting portion 24 is formed in a ring shape in which a portion fitted with the skirt wall upper portion has the same inner diameter as the outer diameter of the skirt wall upper portion. Accordingly, in a state where the cap skirt wall upper fitting portion 24 is attached to the drawing mold portion 23, a step is formed between the lower end surface of the drawing mold portion 23 and the cap skirt wall upper fitting portion 24, and the drawing mold. Configure. The cap skirt wall upper fitting portion 24 is prepared with a plurality of inner diameters according to the outer diameter of the cap skirt wall upper part. It can be measured with one drawing depth gauge. Accordingly, it is also necessary to prepare a zero point calibration gauge corresponding to the outer diameter of the cap skirt wall upper fitting portion.
