【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、アルミニウム箔をプレス成形したしわつき
容器に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wrinkled container obtained by press-molding an aluminum foil.
アルミニウム箔をプレス成形した容器で、側壁及びフラ
ンジにしわが形成されたものは、例えばうどんなどの食
品を収納して、そのまま調理できる容器として普及して
いる。BACKGROUND ART A container formed by press-molding an aluminum foil and having wrinkles formed on a side wall and a flange is widely used as a container that can store, for example, food products such as udon.
このような容器は、特に調理用に使用する場合、充分な
強度が必要である。Such a container needs to have sufficient strength, especially when used for cooking.
ところが、最近のコスト削減の要求により、出来るだけ
薄いアルミニウム箔を用いる一方、構造的には強度の高
い成形容器の必要が高まっている。However, due to the recent demand for cost reduction, there is an increasing need for a molded container having structurally high strength while using as thin an aluminum foil as possible.
そこで、この考案の課題は、強度の大きい構造を有する
アルミニウム箔しわつき容器を提供することである。Then, the subject of this invention is providing the aluminum foil wrinkle container which has a structure with high intensity | strength.
上記の課題を解決するため、この考案は、底壁及びそれ
から立ち上る側壁を有し、この側壁の上端開口部外周に
フランジを設け、このフランジの外周縁に縁巻きを設け
たしわつき容器において、前記フランジの全周にわたっ
て、前記縁巻きから所要巾だけしわを圧縮してリング状
偏平部を形成した構成を採用したのである。In order to solve the above-mentioned problems, the present invention has a bottom wall and a side wall rising from the bottom wall, a flange is provided on an outer periphery of an upper end opening of the side wall, and a wrinkle container is provided with a curl on an outer peripheral edge of the flange, The ring-shaped flat portion is formed by compressing the wrinkle from the edge winding by the required width over the entire circumference of the flange.

容器全体としての強度が向上する。一方垂直方向（フラ
ンジの折れ曲り強度）には、しわによるリブの効果が大
きいが、フランジのしわつき部分がかなり残存しており
かつリング状偏平部がとり巻いているので強度が向上す
る。The wrinkle itself consists of one sheet of aluminum foil, but when it is compressed and flattened, the excess part of the wrinkle overlaps the other part, and the aluminum foil becomes double or triple, Since the flanges are reinforced against horizontal loads and such flanges surround the container,
The strength of the container as a whole is improved. On the other hand, in the vertical direction (the bending strength of the flange), the effect of ribs due to wrinkles is great, but the wrinkled portion of the flange remains considerably and the ring-shaped flat portion surrounds it, so the strength is improved.
以下、この考案の実施例を添付図面に基づいて説明す
る。An embodiment of the present invention will be described below with reference to the accompanying drawings.

る。As shown in FIGS. 1 and 2, an aluminum foil wrinkled container 1 includes a bottom wall 2, a side wall 3 rising from the bottom wall 2, and a flange 5 provided on an outer periphery of an opening 4 at an upper end of the side wall 3, The edge winding 6 is provided on the outer peripheral edge of the flange 5.

うに、偏平部５１は、しわが押しつぶされ、その部分が
重なりあって多重になっている。The bottom wall 2 is flat except for reinforcement unevenness and marks, and the side wall 3 is provided with irregular wrinkles 31 during molding as shown in FIG. Also flange 5
As shown in FIG. 4, the ring-shaped flat portion 51 is compressed from the edge winding 6 by the required width W to form a ring-shaped flat portion 51, and the other wrinkled portions 52 have wrinkles as they are. This state is schematically shown in FIGS. 5 and 6. FIG. 5 is a circumferential cross-section of the flange 5 taken along the line AA in FIG. 2, in which wrinkle unevenness remains as shown in the figure, and the circumference taken along the line BB in FIG. As shown in the directional cross-sectional view, the flat portion 51 has crushed creases, and the portions are overlapped to form a multiple layer.

Has a higher strength with respect to a vertical load as its radius diameter, that is, the so-called top-in R is larger, and has a higher strength with respect to a horizontal load as the top-in R is smaller. Therefore, as shown in FIG. 2, when the opening 4 is formed in a polygonal shape such as an octagon, the top-in R of the shoulder 53 'at the side portion is increased and the top-in R of the shoulder 53 "at the apex portion is increased. If is made small (see FIG. 7), the strength is improved.

部を設け、比較例のものは偏平部を設けていない。The results of measuring the strength of the above-mentioned aluminum foil container and a normal container are shown in FIGS. 8 and 9. The used aluminum foil wrinkled container is an aluminum foil with a thickness of 85μ, the bottom wall diameter is 130.5 mm, the opening diameter is 172.0 mm.
mm, the outer diameter of the flange (including the edging) is 202.0 mm, the capacity is 980 cc. In the comparative example, the flat portion is not provided.
