(産業上の利用分野)
本発明は缶詰用缶胴及びその製造方法に関し、より詳細
には内容物充填後の冷却過程或いはその後の保存中にお

使用金属素材の薄肉化が可能である缶詰用缶胴に関する
。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a can body for canned goods and a method for manufacturing the same, and more specifically, the present invention relates to a can body for canned goods and a method for manufacturing the same. The present invention relates to a can body for canned goods that is resistant and allows the metal material used to be made thinner.
(従来の技術)
従来、缶詰用缶としては、金属板を筒状に成形して対向
する端縁部を溶接、接着或いはハンダ付等の手段で接合
して側面継目付缶胴を成形し、この缶胴の両端を天地蓋
と巻締して成る所謂スリーピース缶や、金属板を有底缶
胴に絞り深絞り成形成いは更にしごき成形に付し、この
有底缶胴の上端に蓋を巻締して成る所謂ツーピース缶が
使用されている。(Prior Art) Conventionally, cans for cans are made by forming a metal plate into a cylindrical shape and joining opposing edges by means such as welding, gluing, or soldering to form a can body with side seams. A so-called three-piece can is produced by seaming both ends of the can body with a top and bottom lid, or a metal plate is drawn into a bottomed can body by deep drawing or ironing, and a lid is attached to the top end of the bottomed can body. A so-called two-piece can is used.
これらの缶詰用缶においては、缶の金属素材コストを低
減させ且つ缶内体を軽量化することを目的として、金属
素材の厚みを可及的に薄くすべく多くの努力が払われて
いる。しかしながら、金属素材の厚みを小さくすると、
缶胴の機械的強度が当然低下し、特に内容物充填後の冷
却過程或いはその後の保存や輸送中に、内部の減圧によ
る缶胴の変形(くぼみ変形)が顕著に生じるようになる
。また、缶詰製品では、その取扱いや輸送中に、缶同士
の衝突等が避は得ないこともあるが、この衝突等によっ
ても缶胴の変形を生じることがある。In these cans, many efforts have been made to reduce the thickness of the metal material as much as possible in order to reduce the cost of the metal material of the can and to reduce the weight of the can interior. However, if the thickness of the metal material is reduced,
The mechanical strength of the can body naturally decreases, and the can body becomes noticeably deformed (concave deformation) due to internal depressurization, especially during the cooling process after filling with contents or during subsequent storage and transportation. Further, in the case of canned products, collisions between cans are sometimes unavoidable during handling and transportation, and these collisions can also cause deformation of the can body.
缶詰製品の缶胴にこのような変形が生じると、製品の外
観が不良となり、商品価値を損うばかりでなく、金属板
の内外保護被覆層にもピンホール、クラック、剥離等の
被覆欠陥を発生し、腐食や金属溶出或いは更に孔食等に
よる漏洩等の問題を起すおそれがある。When such deformation occurs in the can body of a canned product, the product not only has a poor appearance and loses its commercial value, but also causes coating defects such as pinholes, cracks, and peeling in the inner and outer protective coating layers of the metal plate. This may cause problems such as corrosion, metal elution, or even leakage due to pitting corrosion.
従来、缶胴部材を補強する手段として、缶胴部材に周方

凹凸状となって、缶の美観や商品価値が失われると共に
、缶内面にも被覆欠点が表われるようになり、金属露出
(ERV値)が高くなるという欠点がある。このため、
現在実用に供されているビード付缶胴は、缶胴の極く限
られた部分に周状ビードを設けるにとどまっている。Conventionally, as a means for reinforcing a can body member, it has been known to form a bead in the circumferential direction and a bead in the can height direction in the can body member (Problem to be Solved by the Invention) Beads in the can body member Forming a bead is quite effective in preventing the above-mentioned deformation due to reduced pressure, but even if a circumferential bead is provided on the entire surface of the can body member, the deformation load due to external pressure increases (increase in external pressure deformation strength). is at most twice the size of a similar can without a bead, and is still sufficient for the purpose of completely preventing deformation due to decompression even when the metal material is made significantly thinner. In addition, if a bead is formed on the can body, the printed outer surface becomes uneven, detracting from the beauty and commercial value of the can, and coating defects also appear on the inner surface of the can. There is a drawback that metal exposure (ERV value) becomes high. For this reason,
The beaded can bodies currently in practical use only have a circumferential bead in a very limited portion of the can body.
従って、本発明の目的は、従来のビードに代わる新規補
強構造が導入され、外圧(乃至内部減圧)による変形強
度が著しく向上し、外観特性が良好で、しかも缶内面に
おける金属露出も比較的小さい範囲に抑制される缶詰用
缶を提供するにある。Therefore, an object of the present invention is to introduce a new reinforcing structure to replace the conventional bead, which significantly improves the deformation strength due to external pressure (or internal depressurization), has good appearance characteristics, and has relatively little metal exposure on the inner surface of the can. To provide canning cans that are constrained to a range.
本発明の他の目的は、缶外面が組み合わされたに基づく
パネル及びフレームに基ずく特異な立体感と美観とを備
え、缶内容物の喫飲等に際して缶胴の把持も容易であり

供するにある。Another object of the present invention is that the outer surface of the can has a unique three-dimensional effect and aesthetic appearance based on the combined panel and frame, and that the can body is easy to grasp when drinking the contents of the can. To provide a can for canning that also has resistance to dents.

係に設けたものは未だ知られていない。Therefore, the frames are connected to each other and exist continuously, but the panels are independent from each other, and a frame is always interposed between the panels. In the present invention, when the panel is a draw-formed part or an overhang-formed part, the frame is an unprocessed part, and conversely, when the frame is a draw-formed part or an overhang-formed part, the panel is an unprocessed part. Even in conventional bead-type reinforcement structures, there are already structures in which draw-formed or overhang-formed sections and unprocessed sections are provided alternately, but one in which they are provided in the relationship between the panel and the frame described above is still unknown. do not have.

In general, the fact that the panel is located on a cylindrical surface with a relatively small diameter and a constant diameter, while the frame is located on a cylindrical surface that is relatively large and a constant diameter, reduces friction scratches on the outside of the can. This is preferable in terms of preventing damage caused by scratches and dents, but conversely, it is preferable that the panel be located on a cylindrical surface with a relatively large diameter and constant diameter, while the frame be located on a cylindrical surface that is relatively small in diameter and have a constant diameter. Of course, it is also possible to be located at

That is, in the can body of the present invention, in any cross section parallel to the can axis direction and any arbitrary cross section parallel to the can circumferential direction, there is a frame projecting in the radially outward direction and a panel recessed in the radially inward direction, or Panels protruding in the radial outward direction and frames concave in the radial inward direction alternate, and only the panels or only the frames do not exist on these cross sections.

上効果は全く認められない。According to the present invention, the above structural features are combined, a new reinforcing structure is introduced in place of the conventional bead, and the deformation strength due to external pressure (or internal reduced pressure) can be significantly improved. For example, as shown in Examples and Comparative Examples to be described later, an outer diameter of 5 mm using TFS material with a plate thickness of 0.155 mm
0mm, the external pressure resistance of adhesive for can height 120mm is approximately 1
Whereas the external pressure resistance is only on the order of 2 kg/cm2, it is recognized that the external pressure resistance is improved to more than 2 kg/cm'' with the same adhesive except that the new reinforcing structure according to the present invention is introduced. The remarkable improvement in the external pressure resistance of the invention is achieved only when all of the above characteristics are combined. If the panels and frames are not alternately present but are in the same phase, no improvement in external pressure resistance can be observed.

じられる。The fact that the external pressure resistance of the can body of the present invention is significantly improved by introducing the above structure was discovered as a result of numerous experiments and measurements, and although the reason for this is not necessarily clear, , the panels and frames always exist alternately in the can axial direction and the can circumferential direction, and one of the panels and frames is a drawn part or an overhang part, and the panels and frames have different diameters. It is believed that the location on the cylindrical surface improves the bending yield stress in a constant thickness can body and prevents plastic buckling deformation.

。In the can for canning of the present invention, the external pressure resistance can be significantly improved when compared with a constant thickness. As a result, it is possible to save the amount of metal materials used, reduce can manufacturing costs, reduce the weight of the container, and further improve thermal efficiency during heat sterilization.

Moreover, since the panel surface is provided with a relatively large area, metal exposure on the inside of the can is suppressed to a relatively small range compared to conventional bead cans. The presence of the can body makes it easy to hold the can body when drinking or drinking the contents of the can, and it also has excellent resistance to dents.

小さく、耐腐食性に優れている。In the can of the present invention, the drawn portion or the overhang portion constitutes a panel, the unprocessed portion constitutes a frame, the panel is located on a cylindrical surface with a small diameter, and the frame is located on a cylindrical surface with a large diameter. It is particularly preferable that the
In this structure, a panel formed by drawing or stretch forming is located on a small-diameter cylindrical surface inside the unprocessed frame, so that the external pressure resistance is particularly large. Comparing the case where the panel is made to protrude outwards by drawing or stretch forming, and the case where it is made to protrude inwardly, the case where the panel is made to protrude inwardly has stronger resistance to deformation due to the reduced diameter. In this aspect of the invention, since the area of the panel is relatively large, the effect of reducing the diameter is particularly large, and this is combined with the effect of work hardening, resulting in a significant increase in strength. Moreover, since the area of the frame in the unprocessed part is quite small, its influence on the buckling deformation of the entire body is generally small.Thus, in this preferred embodiment, the improvement in external pressure resistance is particularly remarkable. Since the frame has a small area and consists of unprocessed parts, there is less tendency for metal exposure to occur, and it has excellent corrosion resistance.

Of course, the panel of the present invention is not limited to the above-mentioned examples, and may take any shape such as a triangle, quadrangle, pentagon, hexagon, hexagon, other polygons, circle, ellipse, or a combination thereof. Although the panels generally have the same shape, they may be composed of a combination of two or more panels having different shapes. FIG. 2 shows some examples of panel and frame shapes. A is an example in which the panels are rectangular, and not only the panels but also the frames are arranged in an adjacent circumferential direction and an adjacent axial direction with a phase difference of 1/2.

く、耐腐食性に優れている。The drawing part or the stretch forming part constitutes a panel, the unprocessed part constitutes a frame, the panel is located on a cylindrical surface with a small diameter, and the frame is located on a cylindrical surface with a large diameter. In a preferred can, a panel formed by drawing or stretch molding is located on a small diameter cylindrical surface inside the frame of the unprocessed part, so that the external pressure resistance is particularly large. In this aspect of the invention, since the area of the panel is relatively large, the effect of reducing the diameter is particularly large, and this is combined with the effect of work hardening, resulting in a significant increase in strength. Furthermore, since the area of the frame in the unprocessed portion is quite small, the effect this has on the overall buckling deformation, etc., is generally small. Thus, in this preferred embodiment, the improvement in external pressure resistance is particularly remarkable. In addition, since the narrow area of the frame is formed from unprocessed parts, there is little tendency for metal exposure to occur, and it has excellent corrosion resistance.
