いても均一にする方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for making the thickness of an applied plastic layer uniform in a large number of products, and more specifically, a method for making the thickness of a coated plastic layer uniform in a large number of products, and more specifically, a method for forming a push-button can lid opening for beverage cans manufactured in large numbers. This method relates to a method for making the thickness of plastisol uniform for all lids by coating and heating and curing the overlapping part formed by overlapping both sides of the cut part that defines the.
ビール缶なとの缶蓋に、そのパネルの一部を切断して、
注出口または通気口を形成したものがある。Cut a part of the panel into the lid of a beer can.
Some have a spout or vent.
この切断された部分をシールするために、たとえばプラ
スチゾルが、この缶蓋の裏側に塗布される。To seal the cut, plastisol, for example, is applied to the back side of the can lid.
この種の缶蓋は、「押しボタン式缶蓋」とよばれ、その
一例が米国登録意匠第２２６１７１号に示される。This type of can lid is called a "push-button can lid," and an example thereof is shown in U.S. Registered Design No. 226171.
ここで、「押しボタン式缶蓋」とは、缶蓋のパネル部の
一部を切断して開口部となる部分を規定し、その切断部
分の両側を互いに重ね合せ、その重合部を封鎖する封鎖
剤（プラスチゾル）を塗着した缶蓋をいい、開口すると
きは、押しボタンを押す要領で、該開口部を押し下げて
封鎖剤を破断させるものである。Here, "push-button can lid" refers to a method in which a part of the panel of the can lid is cut to define an opening, and both sides of the cut part are overlapped with each other, and the overlapping part is sealed. It refers to a can lid coated with a sealant (plastisol), and when opened, the opening is pushed down, similar to pressing a push button, to break the sealant.
ところで、その重合部に塗着されているプラスチゾルが
厚すぎると、開口に際し必要以上の力を加えなければな
らなくなるので、その厚さを特定の所望厚さにすること
が必要になってくる。By the way, if the plastisol applied to the polymerized part is too thick, it will be necessary to apply more force than necessary to open the opening, so it is necessary to adjust the thickness to a specific desired thickness.
しかし、反面缶内の内容物が使用前に逸出しない程度の
ある最少の厚さのプラスチゾルを使用して缶蓋を適正に
シールする必要もある。However, it is also necessary to properly seal the can lid using a minimum thickness of plastisol that will prevent the contents within the can from escaping prior to use.
これは、すべての押しボタン式缶蓋について必要なこと
である。This is required for all push-button can lids.
本発明は大量生産される缶蓋の不規則な面に、プラスチ

さにする方法を提供するものである。The present invention provides a method for achieving a desired uniform thickness of plastisol on all can lids that are mass-produced on irregular surfaces without curing the plastisol and then aligning the plastisol. It is something to do.
本発明は缶蓋の不規則な面の一部に塗着され、加熱キュ

である。The present invention is a method for uniformizing the thickness of plastisol applied to a part of the irregular surface of a can lid and heated and cured, comprising:
The method is to attach, heat, and while the can lid with the cured and still hot plastisol is transported on a conveyor, the hot plastisol side of the can lid is brought into contact with a roll coated with silicone rubber to flatten the plastisol and create a uniform thickness. It is something to be looked at.
以下、本発明の好ましい具体例を図面で説明する。Hereinafter, preferred embodiments of the present invention will be explained with reference to the drawings.
缶蓋のパネル部の一部を切断して、環状の通気口１７と
注出口１９とを規定し、その切断部の両側を重ね合せた
重合部１８，２０をもつ押しボタン式缶蓋１５の内面１
３側で、該重合部に沿ってプラスチゾル１１を環状に塗
着する。A push-button can lid 15 has an annular vent hole 17 and a spout 19 by cutting a part of the panel portion of the can lid, and has overlapping parts 18 and 20 with both sides of the cut portion overlapped. Inner surface 1
On the third side, plastisol 11 is applied in an annular manner along the polymerized area.
その塗着は周知手段による。The coating is done by known means.
例えば、缶蓋の上方に設置したプラスチゾル塗布ノズル
を、該重合部に沿って移動させながら、プラスチゾルを
ノズルから注出したり、或いは重合部の大きさの環状ノ
ズルから注出したりするなどである。For example, a plastisol application nozzle placed above the can lid is moved along the overlapping area while the plastisol is poured out from the nozzle, or plastisol is poured out from an annular nozzle having the size of the overlapping area.
プラスチゾル１１を塗着してから、缶蓋１５を、コンベ
ア２１に乗せて、プラスチゾルをキュアするキュア用加
熱炉２３を通過させる。After applying the plastisol 11, the can lid 15 is placed on a conveyor 21 and passed through a curing heating furnace 23 for curing the plastisol.
キュアされた熱いプラスチゾルを有する缶蓋１５は、コ
ンベア２１に乗って更に進み、スポンジ状シリコンゴム
２７で被覆したロール２５（図示しないが、ある動力源
で駆動される）の下を通る。The can lid 15 with the cured hot plastisol travels further on the conveyor 21 and passes under a roll 25 (not shown, but driven by some power source) coated with a spongy silicone rubber 27.
コンベア２１の速度はプラスチゾルのキュア時間および
キュア用加熱炉２３の炉長に関連する。The speed of the conveyor 21 is related to the curing time of the plastisol and the length of the curing furnace 23.
ロール２５の周速度はコンベア２１の速度に合せる。The circumferential speed of the roll 25 is matched to the speed of the conveyor 21.
この場合、ロール２５の表面とコンベア２１との距離は
、缶蓋１５の高さより小さく、例えば缶蓋の高さ約５．
７ｍｍ（０，２２５インチ）に対し、前記距離を約３．
１８ｍｍ（０，１２５インチ）とする。In this case, the distance between the surface of the roll 25 and the conveyor 21 is smaller than the height of the can lid 15, for example, about 5.5 mm above the height of the can lid.
For 7 mm (0,225 inches), the distance is approximately 3.
18 mm (0,125 inches).
スポンジ状シリコンゴム２７と接触する前のプラスチゾ
ル１１は、第３図に示すように巾狭且つ厚く塗着され、
しかも、大量生産される缶蓋のすべてに均一に塗布され
ることはなく、バラつきが避けられない。Before coming into contact with the sponge-like silicone rubber 27, the plastisol 11 is coated narrowly and thickly as shown in FIG.
Moreover, the coating is not uniformly applied to all mass-produced can lids, and variations are inevitable.
しかしロールをかけられた後のプラスチゾル１１は第４
図に示すように厚さが減少し、その上面は同一平坦面と
なり、前記重合部において所望厚みとなる。However, plastisol 11 after being rolled is the fourth
As shown in the figure, the thickness decreases and the top surface becomes a coplanar surface, resulting in the desired thickness at the overlap.
シリコンゴムは熱プラスチゾル１１にロールが付着する
のを防止するために使用される。Silicone rubber is used to prevent the roll from sticking to the thermal plastisol 11.
シリコンゴムを柔かくすることが必須であるのでスポン
ジ状シリコンゴムを使用するが、ショアーの硬さ試験機
（Ｚｗｉｃｋ ａｎｄ ＣＯ，製）のＡスケールで測定
したときの硬さが１５〜２１であればたとえば注型シリ
コンゴムのような任意のシリコンゴムを使用することが
できる。Sponge-like silicone rubber is used because it is essential to make the silicone rubber soft, but if the hardness is 15 to 21 when measured on the A scale of a Shore hardness tester (manufactured by Zwick and CO). Any silicone rubber can be used, such as cast silicone rubber.
缶蓋１５はロール２５を通過してからコンベア１２１の
冷却帯に移動する。The can lid 15 passes through the rolls 25 and then moves to the cooling zone of the conveyor 121.
プラスチゾル１１を所望の厚さにするために缶蓋１５と
ロール２５とを心合せする必要が全くないことが認めら
れよう。It will be appreciated that there is no need to align can lid 15 and roll 25 to achieve the desired thickness of plastisol 11.
