〔産業上の利用分野〕
本発明は、塩化ビニールシートを貼り合わせたアルミニ
ウムの板状材を絞り加工し、化粧品容器等のキャップ等
に使用されるカップ形状に成形する加工方法に係る。[Detailed Description of the Invention] [Industrial Application Field] The present invention involves drawing an aluminum plate-like material bonded with a vinyl chloride sheet and forming it into a cup shape used for caps of cosmetic containers, etc. It concerns the processing method.
アルミニウム板へ化成処理層を構成し、その表面に接着
剤層を介在させてロール圧着法により、塩化ビニールシ
ートを貼り合わせた板状の材料を絞り加工してカップ形
状に成形する方法は、従来より用いられている。即ち、
加工後表面処理を施こさなくとも、塩化ビニールシート
層が装飾性の優れた表面処理層となる為である。Conventionally, a chemical conversion treatment layer is formed on an aluminum plate, an adhesive layer is interposed on the surface, and a plate-like material is pasted with a vinyl chloride sheet and then drawn and formed into a cup shape using a roll compression method. It is more used. That is,
This is because the vinyl chloride sheet layer becomes a surface-treated layer with excellent decorative properties even without surface treatment after processing.
前記加工方法に於いて、製品高さをポンチ直径で除した
数値、即ち絞り深さ比を１．０程まで成形し、キャップ
形状に加工すると、アルミニウムの材料の方向性により
、塩化ビニールシートの存在に係りなく耳部が発生する
。該耳部を切削除去しキャップ等として通常利用するも
のである。しかし、耳部を切削除去した端部に化粧料等
に含有されるアルコール等の溶剤骨が付着した時、アル
ミニウムに貼り合わされて加工され伸びた塩化ビニール
シートは、弾性を有して収縮しようと内部応力を有して
いる為、接着層を僅かに溶かす溶剤であっても端部より
７１１離してしまう事が多く発生するものであった。In the above processing method, when the product height divided by the punch diameter, that is, the drawing depth ratio, is formed to about 1.0 and processed into a cap shape, due to the orientation of the aluminum material, the vinyl chloride sheet is Ears occur regardless of their presence. The ears are usually cut off and used as a cap or the like. However, when solvent bones such as alcohol contained in cosmetics etc. adhere to the edges where the ears have been removed, the vinyl chloride sheet that has been bonded to aluminum and processed and stretched becomes elastic and tends to shrink. Because of the internal stress, even with a solvent that slightly dissolves the adhesive layer, the adhesive layer often separates from the edge.
アルミニウムの表面に化成処理層２を構成させ、更に塩
化ビニールシート４を貼り合わせた板状の材料を絞り深

を、６０℃から８０℃の温度に３分間以上加熱処理し、
その後にアルミニウム材料の方向性によって発生する耳
部５を切削除去しキャップ体６を成形する。A chemical conversion treatment layer 2 is formed on the surface of aluminum, and a plate-shaped material in which a vinyl chloride sheet 4 is further bonded is press-formed into a cap shape with a drawing depth ratio of 1.0 or more. This is heat-treated at a temperature of 60°C to 80°C for 3 minutes or more,
Thereafter, the ears 5 generated due to the directionality of the aluminum material are cut off and the cap body 6 is formed.
前記塩化ビニールシート４が、貼り合わせられたアルミ
ニウム板ｌを絞り深さ１．０以上にプレス成形した場合
、アルミニウム板ｌは塑性変形により成形されるが、塩

接着されたまま引っ張られた状態となっている。この内
部応力を有した塩化ビニールシート４は、６０“Ｃから
８０℃に加熱すると伸長し、内部応力となっている収縮
力は除去されるものである。When the vinyl chloride sheet 4 is formed by press-forming bonded aluminum plates l to a drawing depth of 1.0 or more, the aluminum plate l is formed by plastic deformation, but the vinyl chloride sheet 4 is an aluminum plate that undergoes plastic deformation. It is in a stretched state while being glued to 1. The vinyl chloride sheet 4 having this internal stress expands when heated from 60"C to 80°C, and the shrinkage force causing the internal stress is removed.
従って、この後に耳部５を取り去るべく切削除去すれば
剥離しにくいキャップ体６となる。Therefore, if the ears 5 are then cut and removed to remove them, the cap body 6 will be difficult to peel off.

にプレス成形する。この時点で、６０℃の湯の中へ３分
間浸漬し加熱処理をする。A chemical conversion treatment layer 2 was formed on the front and back surfaces of an aluminum plate 1 with a wall thickness of 0.6 mm, and a vinyl chloride sheet 4 with a thickness of Q and 2 mm was bonded together using an adhesive layer 3 using a roll pressure bonding method. Product height: 40 x Diameter: 3
It is press-formed into a 0m5 cab shape, that is, a drawing depth ratio of 1.2 or more. At this point, heat treatment is performed by immersing it in hot water at 60°C for 3 minutes.
この後、湯の中より取り出し耳部５を切削除去しキャッ

ものである。Thereafter, it is taken out of the hot water and the ears 5 are cut and removed to form the cap body 6. A lid body A is completed by inserting and fixing an inner cap 9 made of synthetic resin having a spiral groove 7 carved into the inner wall and housing a top cover 8 into the cap body 6.
上記実施例と同じ材料及びプレス成形にて、製品高さ４
０龍直径３０■ｌのキャップ状体の耳部５を熱処理せず
に切削除去しキャップ体６を形成した。Using the same material and press molding as in the above example, the product height is 4.
A cap body 6 was formed by cutting and removing the ears 5 of a cap-shaped body having a diameter of 30 μl without heat treatment.
この後、合成樹脂製の内キャップ９を挿嵌止着させて蓋
体Ｂを構成した。Thereafter, the inner cap 9 made of synthetic resin was inserted and fixed to form the lid B.
実施例に於いて構成した蓋体Ａ及び比較例に於いて構成

ビニールシート４がｆｆ１ｌ＋離していた。Lid A constructed by immersing lid A constructed in the example and lid B constructed in the comparative example in an 80% ethanol aqueous solution at 30° C. showed no change even after 48 hours.
After 36 hours, the vinyl chloride sheet 4 was circumferentially separated by about 5 mm from the end of the lid B.
実施例に於いて構成した蓋体Ａ及び比較例に於いて構成
した蓋体Ｂを煮沸した。蓋体Ｂは３０分で端部より周状
に塩化ビニールシート４が剥離しはしめたが、蓋体Ａは
６０分経過しても変化が見られなかった。Lid body A constructed in the example and lid body B constructed in the comparative example were boiled. The vinyl chloride sheet 4 of the lid B began to peel off in a circumferential manner from the end after 30 minutes, but no change was observed in the lid A even after 60 minutes.

プ体６を成形する加工方法である。As explained above, the present invention removes the elasticity and tensile force remaining in the vinyl chloride sheet 4 by heat treatment after press forming, that is, the stress that tends to cause peeling. This is a processing method for molding a cap body 6 that does not easily peel off even when the cap body 6 is not easily peeled off.
