Description

本発明は缶胴に幾何学模様を付して立体感を持たせるようにした金属缶に関する。   The present invention relates to a metal can provided with a geometric pattern on a can body to give a three-dimensional feeling.

金属缶の意匠性を高めるための手法として、エンボス加工によって缶胴表面に凹凸模様を形成する方法がある。また、近年では、エンボス加工による凹凸模様と印刷を組み合わせて意匠性を高める技術が開発されている(特許文献1〜3参照)。   As a method for improving the design of the metal can, there is a method of forming an uneven pattern on the surface of the can body by embossing. In recent years, a technique has been developed that improves the design by combining an uneven pattern by embossing and printing (see Patent Documents 1 to 3).

特許文献1は建築用表面材に関する文献であり、金属板の表面に凸エンボス加工を施して凸部を彩色するに際し、凸部と彩色を一致させるための着色方法が記載されている。特許文献2は金属缶の缶胴の模様に関する文献であり、三角形の凹エンボス部をさらに小さい三角形に区分し、隣接する小三角形を高反射部と低反射部とに塗り分けて立体感に変化を付ける方法が記載されている。特許文献3も金属缶の缶胴の模様に関する文献であり、六角形の凹エンボス部に同形同寸の六角形を位相をずらして印刷することにより立体感を持たせ、模様を直方体のように立体的に見せる方法が記載されている。   Patent Document 1 is a document relating to a building surface material, and describes a coloring method for matching a convex portion with a color when a convex embossing is performed on the surface of a metal plate to color the convex portion. Patent Document 2 is a document related to the pattern of the can body of a metal can. The concave embossed portion of the triangle is divided into smaller triangles, and the adjacent small triangles are painted into a high reflection portion and a low reflection portion to change to a three-dimensional effect. The method of attaching is described. Patent Document 3 is also a document related to the pattern of a metal can body. A hexagon having the same shape and the same size is printed on a hexagonal concave embossed portion by shifting the phase to give a three-dimensional effect, so that the pattern looks like a rectangular parallelepiped. Describes a method of making it appear three-dimensionally.

上述した方法はいずれも意匠性を高める効果を奏しているが、エンボス加工と印刷という2つの工程が必要であるために製造効率の点で難がある。また、缶胴の強度を低下させるようなエンボス加工は厳に避けなければならないので、模様の形状や位置にも制限がある。   All of the above-described methods have an effect of improving the designability, but there are difficulties in terms of manufacturing efficiency because two steps of embossing and printing are necessary. In addition, embossing that lowers the strength of the can body must be strictly avoided, so there is a limit to the shape and position of the pattern.

本発明は、上述した背景技術に鑑み、印刷のみで缶胴に立体感を持たせた意匠性の高い金属缶を提供するものである。   In view of the above-described background art, the present invention provides a metal can with high design that gives the can body a three-dimensional effect only by printing.

即ち、本発明は下記[1]〜[5]に記載の構成を有する。   That is, this invention has the structure as described in following [1]-[5].

[1]缶胴の平滑な周壁の少なくとも一部に、多角形のセルの規則的な繰り返しによって形成される幾何学模様が印刷により付され、
前記幾何学模様を構成する多数のセルは3階調以上の同系色で表示分けされ、最も明るい階調を有する最明セルと最も暗い階調を有する最暗セルとがこれらの表示色とは異なる色の境界線で隔てられることなく隣接していることを特徴とする金属缶。
[1] A geometric pattern formed by regular repetition of polygonal cells is attached to at least a part of the smooth peripheral wall of the can body by printing,
A large number of cells constituting the geometric pattern are displayed with similar colors of three or more gradations. The brightest cell having the brightest gradation and the darkest cell having the darkest gradation are the display colors. A metal can characterized by being adjacent to each other without being separated by a border of different colors.

[2]前記最明セルと最暗セルとが隣接する対セルが幾何学模様において同一方向で配置されている前項1に記載の金属缶。   [2] The metal can according to [1], wherein the pair of cells in which the brightest cell and the darkest cell are adjacent are arranged in the same direction in the geometric pattern.

[3]前記最明セルは最も着色の薄いセルであり、最暗セルは最も着色が濃いセルである前項1または2に記載の金属缶。   [3] The metal can according to item 1 or 2, wherein the brightest cell is a lightest colored cell and the darkest cell is a darkest cell.

[4]前記セル内が多段階の階調で表示され、セル内の平均階調をそのセルの階調とする前項1〜3のいずれか1項に記載の金属缶。   [4] The metal can according to any one of [1] to [3], wherein the inside of the cell is displayed with multi-level gradation, and the average gradation in the cell is the gradation of the cell.

[5]前記缶胴にベースコートが付され、前記ベースコート上に幾何学模様が付されている前項1〜4のうちのいずれか1項に記載の金属缶。   [5] The metal can according to any one of items 1 to 4, wherein a base coat is attached to the can body, and a geometric pattern is attached to the base coat.

[6]前記缶胴にベースコートを付することなく前記幾何学模様が付されている前項1〜4のうちのいずれか1項に記載の金属缶。   [6] The metal can according to any one of items 1 to 4, wherein the geometric pattern is attached to the can body without attaching a base coat.

[1]に記載の発明によれば、幾何学模様を構成するセルを3階調以上の同系色で表示分けすることによって、缶胴の平坦な周壁に凹凸が存在するように見せることができる。   According to the invention described in [1], the cells constituting the geometric pattern can be displayed with three or more similar colors, so that the flat peripheral wall of the can body can appear to be uneven. .

前記幾何学模様はエンボス加工を行わず印刷のみによって立体感を作り出したものであるから、少ない工程で意匠性の高い缶胴を効率良く製造できる。また、立体感は印刷による視覚的効果によるものであるから、模様が缶胴強度維持のために制限されることがなく、デザインの自由度が大きく、幾何学模様を付する位置や領域も自由である。   Since the geometric pattern creates a three-dimensional effect only by printing without embossing, it is possible to efficiently produce a can body having high design properties with a small number of processes. In addition, since the three-dimensional effect is due to the visual effect of printing, the pattern is not limited to maintain the can body strength, the degree of freedom of design is large, and the position and area where the geometric pattern is attached is also free It is.

[2]に記載の発明によれば、最明セルと最暗セルの対セルが幾何学模様において同一方向で配置されているので明暗のコントラストが明瞭であり、特定方向から光が当たっているかのように見えてより一層立体感を感じさせるものとなる。   According to the invention described in [2], since the paired cells of the brightest cell and the darkest cell are arranged in the same direction in the geometric pattern, the contrast between light and dark is clear and whether light strikes from a specific direction. It looks like this and makes it feel more three-dimensional.

[3]に記載の発明によれば、印刷時の着色の濃淡によってセルの明暗を容易に設定することができる。   According to the invention described in [3], the lightness and darkness of the cells can be easily set according to the color shade at the time of printing.

[4]に記載の発明によれば、幾何学模様に、より一層立体感を持たせることができる。   According to the invention described in [4], the geometric pattern can have a more three-dimensional effect.

[5]に記載の発明によれば、ベースコートによって缶胴表面の金属光沢が打ち消されるので、淡い色使いや明度差の小さい幾何学模様でもくっきりと見せることができ、安定した立体感を作り出すことができる。   According to the invention described in [5], since the metallic luster on the surface of the can body is canceled by the base coat, it is possible to clearly display even a light color or a geometric pattern with a small difference in brightness, thereby creating a stable three-dimensional effect. Can do.

[6]に記載の発明によれば、幾何学模様の背後に缶胴の金属光沢が透けて見えるので、幾何学模様に光輝性が付加されてベースコート付きのものとは違った趣となる。また、缶胴の置かれている背景や照明が缶胴に映り込み、またそれらが見る角度によって変化するので複雑な立体感が作り出される。   According to the invention described in [6], the metallic luster of the can body can be seen through behind the geometric pattern, so that the geometric pattern is added with glitter and has a different taste from that with the base coat. In addition, the background and lighting on which the can body is placed is reflected in the can body, and it changes depending on the angle at which they are viewed, creating a complex three-dimensional effect.

本発明にかかる、幾何学模様が付された缶胴の一実施形態の斜視図である。1 is a perspective view of an embodiment of a can body with a geometric pattern according to the present invention. 図1の缶胴に付された幾何学模様を構成するセルユニットの拡大図である。It is an enlarged view of the cell unit which comprises the geometric pattern attached | subjected to the can body of FIG. 他の幾何学模様を示す図である。It is a figure which shows another geometric pattern. さらに他の幾何学模様を示す図である。It is a figure which shows another geometric pattern. さらに他の幾何学模様を付した缶胴の斜視図である。FIG. 6 is a perspective view of a can body with still another geometric pattern. 図5の缶胴に付された幾何学模様を構成するセルユニットの拡大図である。It is an enlarged view of the cell unit which comprises the geometric pattern attached | subjected to the can body of FIG.

図1は飲料用アルミニウム缶の有底円筒形の缶胴(1)であり、上部のネック加工前の状態を示している。前記缶胴(1)の周壁は平滑であり、その外周面には幾何学模様(2)が印刷によって付されている。   FIG. 1 shows a bottomed cylindrical can body (1) of an aluminum can for beverages, and shows a state before processing an upper neck. The peripheral wall of the can body (1) is smooth, and a geometric pattern (2) is attached to the outer peripheral surface thereof by printing.

前記幾何学模様(2)は、図2に示す菱形のセルユニット(10)が周方向および缶軸方向に規則的に繰り返すことにより形成されている。前記セルユニット(10)は繰り返しの最小単位であり、同形同寸ではあるが向きの異なる6個の二等辺三角形のセル(a)(b)(c)(d)(e)(f)の組み合わせによって形成され、かつこれらのセル(a)(b)(c)(d)(e)(f)は階調の異なる同系色で表示分けされている。   The geometric pattern (2) is formed by regularly repeating the rhomboid cell unit (10) shown in FIG. 2 in the circumferential direction and the can axis direction. The cell unit (10) is a minimum unit of repetition, and isosceles six cells having the same shape and the same size but different directions (a) (b) (c) (d) (e) (f) These cells (a), (b), (c), (d), (e), and (f) are displayed and divided in similar colors with different gradations.

本発明において、セルの階調数は3階調以上であり、最も明るい階調を有する最明セルと最も暗い階調を有する最暗セルとの間に少なくとも1つの中間階調のセルを有する。図示例の幾何学模様(2)は、セルユニット(10)中の6個のセルの階調が全て異なり、セル(c)が最明セルであり、以下、セル(f)、セル(b)、セル(e)、セル(a)の順に暗くなり、セル(d)が最暗セルである。   In the present invention, the number of gradations of the cell is 3 or more, and at least one intermediate gradation cell is provided between the brightest cell having the brightest gradation and the darkest cell having the darkest gradation. . The geometrical pattern (2) in the example shown in the figure shows that the six cells in the cell unit (10) are all different in gradation, and the cell (c) is the brightest cell. Hereinafter, the cell (f), cell (b ), Cell (e), and cell (a) become darker in this order, and cell (d) is the darkest cell.

また、最明セル(c)と最暗セル(d)は隣接する対セルであり、幾何学模様(2)はこの対セルを多数有している。   The brightest cell (c) and the darkest cell (d) are adjacent cell pairs, and the geometric pattern (2) has a large number of cell pairs.

図1に示すように、幾何学模様(2)を構成するセル(a)(b)(c)(d)(e)(f)を3階調以上の同系色で表示分けすることによって、缶胴(1)の平坦な周壁に凹凸が存在するように見せることができる。3階調以上とするのは、明と暗の2階調では立体感が乏しいためである。階調数に上限はなく、模様に応じて任意の階調数を設定することができる。また、同系色で階調のみを変えるのは、異なる色調で階調差を付けても自然な立体感を得にくいからである。さらに、本発明においては、最明セル(c)と最暗セル(d)との間にこれらの表示色とは異なる色の境界線を引かないことも自然な立体感を表すための手法である。ただし、中間階調のセル(a)(b)(e)(f)同士、最明セル(c)と中間階調のセル(a)(b)(e)(f)、最暗セル(d)と中間階調のセル(a)(b)(e)(f)は明度差が小さいので、立体感を損なわない限り境界線を表示しても良い。   As shown in FIG. 1, the cells (a), (b), (c), (d), (e), and (f) constituting the geometrical pattern (2) are displayed and divided by three or more similar colors, It can be seen that there are irregularities on the flat peripheral wall of the can body (1). Three or more gradations are used because the three-dimensional effect is poor at two gradations, light and dark. There is no upper limit to the number of gradations, and an arbitrary number of gradations can be set according to the pattern. The reason why only the gradation is changed in the similar color is that it is difficult to obtain a natural three-dimensional effect even if a gradation difference is applied with different color tones. Furthermore, in the present invention, it is a technique for expressing a natural three-dimensional effect that a boundary line of a color different from these display colors is not drawn between the brightest cell (c) and the darkest cell (d). is there. However, the cells (a), (b), (e), and (f) of the intermediate gradation, the brightest cell (c), the cells (a), (b), (e), and (f) of the intermediate gradation, and the darkest cell ( Since the difference in brightness is small between d) and the cells (a), (b), (e), and (f) of the intermediate gradation, boundary lines may be displayed as long as the stereoscopic effect is not impaired.

また、最明セル(c)と最暗セル(d)の対セルは幾何学模様(2)において同一方向で配置されているので明暗のコントラストが明瞭であり、特定方向(図1の場合は、缶軸方向の上部)から光が当たっているかのように見えてより一層立体感を感じさせる。また、前記効果は、特に水平線(缶胴の周方向線)または水平線に近い角度の線の上下に最明セル(c)と最暗セル(d)が配置されている場合に顕著である。また、最明セルと最暗セルとはどちらが上であっても同様の効果が得られる。本実施形態の幾何学模様(2)は水平線の上に最明セル(c)を配し、下に最暗セル(d)を配したものである。この場合、セル(a)(b)(c)、およびセル(d)(e)(f)からなる図形が缶胴表面から缶軸に向かって三角錐状に凹んでいるような立体感を得ることができ、セルユニット(10)を繰り返すことよって規則的な凹凸を感じさせる幾何学模様(2)となっている。なお、最明セルと最暗セルの上下が逆になった場合は、凹凸が逆になって見える。   The brightest cell (c) and the darkest cell (d) are arranged in the same direction in the geometric pattern (2), so the contrast of light and dark is clear, and the specific direction (in the case of FIG. 1) The upper part in the can axis direction) makes it appear as if the light is shining on it, making it feel more three-dimensional. The above-mentioned effect is particularly remarkable when the brightest cell (c) and the darkest cell (d) are arranged above and below a horizontal line (a circumferential line of the can body) or a line having an angle close to the horizontal line. Further, the same effect can be obtained regardless of which is the brightest cell or the darkest cell. The geometric pattern (2) of the present embodiment is one in which the brightest cell (c) is arranged on the horizontal line and the darkest cell (d) is arranged below. In this case, the three-dimensional effect that the figure made of the cells (a), (b), (c), and the cells (d), (e), and (f) is recessed in a triangular pyramid shape from the can body surface toward the can axis. Geometric pattern (2) that can be obtained and feel regular irregularities by repeating cell unit (10). In addition, when the top and bottom of the brightest cell and the darkest cell are reversed, the unevenness appears to be reversed.

セルの明るさは、例えばJIS Z 8729で規定されるL表色系の明度(L)によって表すことができる。最明セル(c)と最暗セル(d)とは明度(L)として4.0以上の差があることが好ましい。明度差(L)差が4.0未満では立体感が乏しい。特に好ましい明度(L)の差は4.4〜10.0である。また、辺で隣接するセル間の明度(L)の差は0.5〜10.0が好ましく、特に0.7〜8.0が好ましい。
また、最明セル(c)の明るさ100とし他のセルの明るさを相対的に表すと、最暗セル(d)の明るさは80.0〜96.0の範囲が好ましく、特に90.0〜95.0の範囲が好ましい。また、辺で隣接するセル間の明るさの差は、最明セルの明るさ100として0.5〜12.0の範囲が好ましく、特に0.9〜9.0の範囲が好ましい。
The brightness of the cell can be represented by, for example, the lightness (L * ) of the L * a * b * color system defined by JIS Z 8729. The lightest cell (c) and the darkest cell (d) preferably have a difference of 4.0 or more in lightness (L * ). If the lightness difference (L * ) difference is less than 4.0, the stereoscopic effect is poor. A particularly preferable difference in lightness (L * ) is 4.4 to 10.0. Further, the lightness (L * ) difference between adjacent cells on the side is preferably 0.5 to 10.0, and particularly preferably 0.7 to 8.0.
When the brightness of the brightest cell (c) is 100 and the brightness of other cells is relatively expressed, the brightness of the darkest cell (d) is preferably in the range of 80.0 to 96.0, particularly 90. A range of 0.0 to 95.0 is preferred. Further, the difference in brightness between adjacent cells on the side is preferably in the range of 0.5 to 12.0 as the brightness 100 of the brightest cell, and particularly preferably in the range of 0.9 to 9.0.

最小セルであるセル(a)(b)(c)(d)(e)(f)内は単一階調で表示することも、多段階の階調で表示することもできる。多段階階調による表示とは、例えば、一定方向に沿って明から暗に、または暗から明に連続的に変化するグラデーションである。セル内を多段階階調で表示する場合はセル内の平均階調をそのセルの階調とする。このようにセル内でグラデーションを付けることによって、幾何学模様に、より一層立体感を持たせることができる。
また、幾何学模様を構成するセルの一部にのみグラデーションをつけて表示することも任意である。
The cells (a), (b), (c), (d), (e), and (f), which are the smallest cells, can be displayed with a single gradation or with multiple gradations. The display with multi-level gradation is, for example, gradation that changes continuously from bright to dark or from dark to bright along a certain direction. When a cell is displayed with multi-level gradation, the average gradation in the cell is used as the gradation of the cell. By adding gradation in the cell in this way, the geometric pattern can be given a more three-dimensional effect.
It is also optional to display a gradation only on a part of the cells constituting the geometric pattern.

前記幾何学模様(2)は印刷によって付するものであるから、各セル(a)(b)(c)(d)(e)(f)の階調は印刷時のインクの色、インクの付着量によって設定することができる。例えば、インクの付着量を少なくして着色を薄くすることによって明るい階調の色が得られ、インクの付着量を多くして着色を濃くすることによって暗い階調の色が得られる。このように印刷時の着色の濃淡によってセルの明暗を容易に設定することができる。また、網点印刷においては、ドットの密度やドットの直径を変えることによって階調差を出すことができるが、これらもインクの付着量の差によって階調を表す手法である。   Since the geometric pattern (2) is attached by printing, the gradation of each cell (a) (b) (c) (d) (e) (f) is the color of the ink at the time of printing, It can be set according to the amount of adhesion. For example, a light gradation color can be obtained by reducing the amount of ink attached to lighten the color, and a dark gradation color can be obtained by increasing the amount of ink attached to increase the coloration. In this way, the lightness and darkness of the cells can be easily set according to the shade of coloring during printing. In halftone printing, a gradation difference can be obtained by changing the density of dots and the diameter of the dots, and these are also techniques for representing gradation by the difference in the amount of ink attached.

また、セルの階調は幾何学模様(2)を印刷する缶胴(1)の表面色の影響も受ける。一般的な缶胴印刷においては、ベースコートを塗装してその上に模様の印刷を行う場合と、ベースコートを塗装せずに直接模様の印刷を行う場合とがある。本発明においてもベースコートの有無は任意に選択することができ、それぞれに特徴のある立体感を作り出すことができる。   The cell gradation is also affected by the surface color of the can body (1) on which the geometric pattern (2) is printed. In general can body printing, there are a case where a base coat is applied and a pattern is printed thereon, and a case where a pattern is directly printed without applying the base coat. Also in the present invention, the presence or absence of the base coat can be arbitrarily selected, and each of the three-dimensional effects can be created.

ベースコートを塗装した場合は缶胴表面の金属光沢が打ち消されるので、淡い色使いや明度差の小さい幾何学模様でもくっきりと見せることができ、安定した立体感を作り出すことができる。また、ベースコート上にインクを塗布しなければベースコートの色をそのままセルの表示色の一つとして利用できる。前記ベースコートが白色であれば、そのセルは最明セルとなる。   When the base coat is applied, the metallic luster on the surface of the can body is canceled out, so even light colors and geometric patterns with small brightness differences can be clearly displayed, creating a stable three-dimensional effect. If no ink is applied on the base coat, the base coat color can be used as it is as one of the display colors of the cells. If the base coat is white, the cell is the brightest cell.

一方、ベースコートを塗装しない場合は、幾何学模様の背後に缶胴の金属光沢が透けて見えるので、幾何学模様に光輝性が付加されてベースコート付きのものとは違った趣となる。また、インクを塗布しないセルは金属光沢がそのまま表示色となるから、ひときわ光輝性の高いセルとなる。また、缶胴の置かれている背景や照明が缶胴に映り込み、またそれらが見る角度によって変化するので複雑な立体感が作り出される。また、印刷で形成した階調に背景等が映り込むことでセルの階調の順序(明るさの順序)が入れ替わることもあるので、なお一層複雑な立体感が作り出される。   On the other hand, when the base coat is not applied, the metallic luster of the can body can be seen behind the geometric pattern, so that the glitter is added to the geometric pattern, which is different from the one with the base coat. Further, since the cell without the ink applied has the metallic luster as it is as the display color, it becomes a cell with extremely high glitter. In addition, the background and lighting on which the can body is placed is reflected in the can body, and it changes depending on the angle at which they are viewed, creating a complex three-dimensional effect. Further, since the background or the like is reflected in the gradation formed by printing, the order of the gradation of the cells (brightness order) may be changed, so that an even more complicated stereoscopic effect is created.

前記幾何学模様はエンボス加工を行わず印刷のみによって立体感を作り出したものであるから、少ない工程で意匠性の高い缶胴を効率良く製造できる。缶胴の製造ラインには缶胴の外面印刷の工程も組み込まれているので、印刷内容の変更だけで実施可能である。また、エンボス加工であれば缶胴強度を低下させないためにセルの形状、寸法、数が制限されるが、本発明は印刷による視覚的効果によって立体感を得たものであるから、模様が缶胴強度維持のために制限されることがなく、デザインの自由度が大きく、幾何学模様を付する位置や領域も自由である。   Since the geometric pattern creates a three-dimensional effect only by printing without embossing, it is possible to efficiently produce a can body having high design properties with a small number of processes. Since the can body production line also includes a process for printing the outer surface of the can body, it can be carried out only by changing the printing contents. In addition, although the shape, size, and number of cells are limited in order to prevent the can body strength from being lowered if embossing is performed, the pattern is a can because the present invention has a three-dimensional effect due to the visual effect of printing. There is no restriction for maintaining the trunk strength, the degree of freedom in design is large, and the position and area where the geometric pattern is attached is also free.

本発明において、幾何学模様は、多角形セルの規則的繰り返しによるものである限り、形状は自由である。また、形状や寸法の異なるセルを組み合わせることも自由である。図3の幾何学模様(3)は同形の4個の三角形の組み合わせによる模様であり、缶胴の表面から四角錐が突出しているような立体感が得られる。図4の幾何学模様(4)は寸法、形状の異なる三角形の組み合わせによって複雑な凹凸を感じさせる模様である。また、図5および図6の幾何学模様(5)は6個の同形同寸の二等辺三角形のセル(a’)(b)(c)(d’)(e)(f)を組み合わせたセルユニット(11)を繰り返して形成したものである。前記セルユニット(11)は図2のセルユニット(10)と同一形状であるがセルの階調の順序が異なり、最明セルがセル(c)であり、以下、セル(f)、セル(b)、セル(e)、セル(d’)の順に暗くなり、セル(a’)が最暗セルである。前記セルユニット(11)を繰り返す幾何学模様(5)の場合は、缶軸方向の左上から右下に向けて45°の角度から光が当たっているかのように見えている。   In the present invention, the geometric pattern is free as long as it is a regular repetition of polygonal cells. It is also possible to combine cells having different shapes and dimensions. The geometrical pattern (3) in FIG. 3 is a pattern of a combination of four triangles having the same shape, and a three-dimensional effect is obtained such that a quadrangular pyramid protrudes from the surface of the can body. The geometric pattern (4) in FIG. 4 is a pattern that makes a complex unevenness feel by combining triangles with different dimensions and shapes. The geometric pattern (5) in FIGS. 5 and 6 is a combination of six isosceles cells (a ′), (b), (c), (d ′), (e), and (f) having the same dimensions. The cell unit (11) is formed repeatedly. The cell unit (11) has the same shape as the cell unit (10) of FIG. 2, but the order of cell gradation is different, and the brightest cell is the cell (c). Hereinafter, the cell (f), cell ( b) It becomes dark in the order of cell (e) and cell (d ′), and cell (a ′) is the darkest cell. In the case of the geometrical pattern (5) in which the cell unit (11) is repeated, it appears as if light is shining from an angle of 45 ° from the upper left to the lower right in the can axis direction.

The shape of the metal can is not limited except that the peripheral wall of the can body is flat, a two-piece can that attaches a lid by forming a flange at the neck, and a three-piece that attaches a bottom and a lid to a bottomless can body The present invention can be applied to both a can and a bottle can in which a base having a male screw portion is formed on the top of the can body and a screw cap is attached to the base. In addition to a metal can printed directly on a can body, a metal can in which a geometric pattern is printed on a film in advance and the printed film is wound around the can body is also included in the present invention.

アルミニウム製の有底円筒形の缶胴(1)に、図1、2に参照される幾何学模様(2)および図5、6に参照される幾何学模様(5)を印刷した。   A geometric pattern (2) referred to in FIGS. 1 and 2 and a geometric pattern (5) referred to in FIGS. 5 and 6 were printed on an aluminum bottomed cylindrical can body (1).

缶胴(1)は直径66mmのDI缶であり、周壁は凹凸の無い平滑壁である。印刷領域は缶軸方向に115mm×円周方向に約207mmである。缶胴(1)は、外周面に白色のベースコートを塗装したもの(A)と、ベースコートなしの鏡面仕上げ(B)の2種類を準備した。   The can body (1) is a DI can having a diameter of 66 mm, and the peripheral wall is a smooth wall without irregularities. The printing area is 115 mm in the can axis direction × about 207 mm in the circumferential direction. Two types of can bodies (1) were prepared: one with a white base coat applied to the outer peripheral surface (A) and a mirror finish without base coat (B).

印刷は、幾何学模様(2)(5)と階調の形成を黒インクによる網点印刷で行い、さらに色彩を加えるために4色のカラーインクによるベタ塗りを行った。これらの幾何学模様(2)(5)は、セルユニット(10)(11)の形状が同一であり、セルユニット(10)(11)を構成するセルの階調の順序が異なる。   For printing, geometric patterns (2) and (5) and gradation were formed by halftone dot printing with black ink, and in order to add color, solid coating with four color inks was performed. In these geometric patterns (2) and (5), the shape of the cell units (10) and (11) is the same, and the order of gradation of the cells constituting the cell units (10) and (11) is different.

網点印刷はインクの塗布量を変えることによって6段階の階調を形成し、図2示す6個のセル(a)(b)(c)(d)(e)(f)からなるセルユニット(10)を形成し、このセルユニット(10)の繰り返しによる幾何学模様(2)の形成を行った。前記セルユニット(10)において、セル(c)は黒インクを塗布しないセルである。また、セル(a)(b)(d)(e)(f)は所定の方向に沿って漸次黒インクの塗布量を減じ、セル内でグラデーションをつけた。同様にして、図6に示す6個のセル(a’)(b)(c)(d’)(e)(f)からなるセルユニット(11)を形成し、このセルユニット(11)の繰り返しによる幾何学模様(5)の形成を行った。   Halftone printing forms six levels of gradation by changing the amount of ink applied, and is a cell unit comprising six cells (a) (b) (c) (d) (e) (f) shown in FIG. (10) was formed, and the geometric pattern (2) was formed by repeating this cell unit (10). In the cell unit (10), the cell (c) is a cell to which black ink is not applied. In the cells (a), (b), (d), (e), and (f), the application amount of the black ink was gradually decreased along a predetermined direction, and gradation was given in the cells. Similarly, a cell unit (11) comprising six cells (a ′) (b) (c) (d ′) (e) (f) shown in FIG. 6 is formed, and the cell unit (11) The geometric pattern (5) was formed by repetition.

表1に図2のセルユニット(10)における各セル(a)(b)(c)(d)(e)(f)のグラデーションの角度と塗布量を示し、表2に図6のセルユニット(11)における各セル(a’)(b)(c)(d’)(e)(f)のグラデーションの角度と塗布量を示す。グラデーションの方向とは黒インクの塗布量が少なくなる方向であり、水平線上の左向きを0°とし、0°から反時計回りにプラス角度、時計回りにマイナス角度で表しし、水平線に沿って右向きの方向を180°で表した。また、黒インクの塗布量は相対値で表すものとし、数字が小さくなるほど塗布量が少なくなる。表1より、セルユニット(10)において、塗布量の最も少ないセルは塗布しない(塗布量が0)セル(c)であり、以下、(f)(b)(e)(a)(d)の順で黒インクの塗布量が増え、セル(d)が最も塗布量が多い。また、表2より、セルユニット(11)において、塗布量の最も少ないセルは塗布しない(塗布量が0)セル(c)であり、以下、(f)(b)(e)(d’)(a’)の順で黒インクの塗布量が増え、セル(a’)が最も塗布量が多い。   Table 1 shows the gradation angle and application amount of each cell (a) (b) (c) (d) (e) (f) in the cell unit (10) of FIG. 2, and Table 2 shows the cell unit of FIG. The gradation angle and the coating amount of each cell (a ′), (b), (c), (d ′), (e), and (f) in (11) are shown. The direction of gradation is the direction in which the amount of black ink applied decreases, with the left direction on the horizontal line being 0 °, expressed as a positive angle counterclockwise from 0 °, a negative angle clockwise, and rightward along the horizontal line. The direction of was represented by 180 °. The application amount of black ink is expressed as a relative value, and the application amount decreases as the number decreases. From Table 1, in the cell unit (10), the cell with the smallest coating amount is not coated (coating amount is 0), which is the cell (c), and hereinafter (f) (b) (e) (a) (d) In this order, the application amount of black ink increases, and the cell (d) has the largest application amount. Further, from Table 2, in the cell unit (11), the cell with the smallest coating amount is not coated (coating amount is 0), which is the cell (c), and hereinafter (f) (b) (e) (d ') The amount of black ink applied increases in the order of (a ′), and the cell (a ′) has the largest amount of application.

ベースコート付缶胴(A)およびアルミニウム鏡面缶胴(B)に上記の網点印刷を行った。セル(c)は黒インクを塗布していないので、各缶胴(A)(B)の表面色がそのままセル(c)の表示色である。これにより、6階調のセルによる幾何学模様(2)(5)が形成された。   The above halftone printing was performed on the base drum with base coat (A) and the aluminum mirror can body (B). Since the cell (c) is not coated with black ink, the surface color of each can body (A) (B) is the display color of the cell (c) as it is. As a result, geometrical patterns (2) and (5) were formed by six gradation cells.

さらに、前記網点印刷の上に、グレー(黒20%+白80%)、黄、赤、青のカラーインクによる塗装を行った。塗装は階調を付けることなく均一量のカラーインクを塗布した。カラーインクは塗布量が少ないので6階調の幾何学模様(2)(5)が透けて視認でき、色彩の加わった幾何学模様(2)となった。   Further, on the halftone dot printing, painting with gray (black 20% + white 80%), yellow, red and blue color inks was performed. For coating, a uniform amount of color ink was applied without gradation. Since the color ink was applied in a small amount, the geometric pattern (2) (5) with 6 gradations could be seen through and became a geometric pattern (2) with added color.

2種類の幾何学模様(2)(5)について、それぞれ、網点印刷のみを行った缶胴を加え、2種類(A、B)×5カラー(網点印刷のみ、網点印刷+グレー、網点印刷+黄、網点印刷+赤、網点印刷+青)=10種の幾何学模様付の缶胴を得た。これら10種類の缶胴を目視観察したところ、幾何学模様はいずれも立体感を感じさせるものであり、印刷によって立体感を作り出すという作用を奏していた。   For the two types of geometric patterns (2) and (5), add a can body that has only halftone dot printing, and add two types (A, B) x 5 colors (halftone dot printing only, halftone dot printing + gray, Halftone dot printing + yellow, halftone dot printing + red, halftone dot printing + blue) = 10 can bodies with geometric patterns were obtained. When these ten kinds of can bodies were visually observed, all of the geometric patterns gave a three-dimensional effect, and the effect of creating a three-dimensional effect by printing was exhibited.

さらに、各10種類の缶胴について、幾何学模様(2)(5)のセルユニット(10)(11)における6つのセル(a)(b)(c)(d)(e)(f)、(a’)(b)(c)(d’)(e)(f)のL表色系の明度(L)、色度(a)(b)を測定した。測定は、分光色測計(コニカミノルタ株式会社、M−700d)を用い、SCI(Specular Component Include)方式で受光角度を8°とし、測定口径をφ3mm(安定板なし)として測定した。なお、測定は各セルの中心部分で行い、中心における明度および色度をそのセルの平均明度および平均色度とした。セルユニット(10)の測定値を表3に示し、セルユニット(11)の測定値を表4に示す。また、最も高い明度を示したセルをL比率=100.0とし、他のセルを相対値で表した。また、L比率の大きいものから小さいものの順に順位をつけた。即ち、順位「1」のセルが最明セルであり、順位「6」のセルが最暗セルである。 Furthermore, for each of the 10 types of can bodies, the six cells (a) (b) (c) (d) (e) (f) in the cell units (10) (11) of the geometric pattern (2) (5) , (A ') (b) (c) (d') (e) (f) L * a * b * color system lightness (L * ), chromaticity (a * ) (b * ) did. The measurement was performed using a spectrocolorimeter (Konica Minolta Co., Ltd., M-700d), with a SCI (Specular Component Include) method, a light receiving angle of 8 °, and a measurement aperture of 3 mm (no stabilizer). The measurement was performed at the center of each cell, and the brightness and chromaticity at the center were defined as the average brightness and average chromaticity of the cell. The measured values of the cell unit (10) are shown in Table 3, and the measured values of the cell unit (11) are shown in Table 4. Moreover, the cell which showed the highest brightness was made into L ratio = 100.0, and the other cell was represented by the relative value. In addition, the ranking was given in the order from the largest L ratio to the smallest L ratio. That is, the cell with the rank “1” is the brightest cell, and the cell with the rank “6” is the darkest cell.

表3、4の結果より、ベースコート付缶胴(A)およびアルミニウム鏡面缶胴(B)ともに幾何学模様(2)(5)を構成する6つのセル(a)(b)(c)(d)(e)(f)、(a’)(b)(c)(d’)(e)(f)の明るさの順序は黒インクの塗布量の順序に合致していた。   From the results of Tables 3 and 4, the six cells (a), (b), (c), and (d) that constitute the geometric pattern (2) and (5) in both the base coat can body (A) and the aluminum mirror surface can body (B). ) (E) (f), (a ′) (b) (c) (d ′) (e) (f), the order of brightness matched the order of black ink application amounts.
