High-speed laser marking on goods

Abstract

To improve the placement of laser marks on an object in order to provide both precision and speed. [Solution] A laser-marked article having a predetermined feature marking on a wall surface, which is user-readable, machine-readable, or both. Also, a method for producing an article marked by laser marking.

Claims

1. An article (10) marked by a pulse-raising device (200), wherein the article is The main body including the wall material, A predetermined feature portion (17) incorporated into at least a portion of the wall material, wherein the predetermined feature portion includes a plurality of marks (12) of a grid pattern (16) including a plurality of positions (11, 12) arranged along a series of substantially parallel rows (48), Each pair of adjacent positions along any of the substantially parallel columns is separated by a distance X (41), Each adjacent pair of parallel columns is separated by a distance Y (43). The aforementioned Y distance is different from the aforementioned X distance, Articles stacked between adjacent parallel rows.

2. The article according to claim 1, wherein the predetermined feature portion includes at least one alphanumeric character (14).

3. The article according to claim 2, wherein the alphanumeric characters have a font size in the range of 6pt to 10pt, and the Y distance is 1.2 to 2 times the X distance.

4. The article according to claim 2, wherein the alphanumeric characters have a font size in the range of 11pt to 16pt, and the Y distance is 2 to 4 times the X distance.

5. The article according to claim 1, wherein the article is a container (10) further comprising an opening (11) and a base, the main body portion comprising one or more wall portions extending from the opening to the base and surrounding an internal space (15), the one or more wall portions having an inner surface and an outer surface, and the opening is in fluid communication with the internal space.

6. The article according to claim 5, wherein the container further comprises a neck portion (13) adjacent to the opening.

7. The article according to claim 5, wherein the main body portion includes a first surface and a second surface, the first surface having an ink-containing decoration, and the second surface does not contain ink and includes the plurality of marks.

8. The wall material further comprises a laser absorption additive, the laser absorption additive being titanium dioxide (TiO2). 2 ), antimony tin oxide (ATO), ATO-coated substrates (e.g., ATO-coated mica), indium tin oxide (ITO), Sb 2 O 3 The article according to claim 1, comprising tin oxide, carbon black, graphite carbon, bismuth oxide, mixed metal oxides, metal nitrides, doped metal nitrides, metal carbides, metal borides, pearlescent pigments, zero-valent metals, doped tungsten oxide, tungsten oxide, doped tungsten oxide, and mixtures thereof.

9. An article marked by a pulse-raising device, the article is The main body including the wall material, The main body portion comprises a predetermined feature portion incorporated into at least a part thereof, The predetermined feature portion includes at least one alphanumeric character formed by a plurality of marks in a grid pattern including a plurality of positions arranged along a series of substantially parallel rows, Each pair of adjacent positions along any of the aforementioned parallel columns is separated by a distance of X. Each adjacent pair of parallel columns is separated by a distance Y. The aforementioned Y distance is different from the aforementioned X distance, The aforementioned positions between adjacent parallel columns are stacked, An article in which the multiple marks forming the alphanumeric characters are not enclosed by a boundary.

10. The article according to claim 9, wherein the alphanumeric characters have a font size in the range of 6pt to 10pt, and the Y distance is 1.2 to 2 times the X distance.

11. The article according to claim 9, wherein the alphanumeric characters have a font size in the range of 11pt to 16pt, and the Y distance is 2 to 4 times the X distance.
