Abstract

A redeemable carbonated beverage can on the lid of which there is provided a pair of spaced, redundant, arcuately distributed code patches containing regional redemption information. The code patches are read by a scanning laser beam. These patches may be formed in several different ways, as by impressing them, embossing them, or printing them. Information in the patches may be coded in any convenient manner, as, for example, in a binary-type code or in a frequency-type code.

Claims

1. In a redeemable carbonated beverage container or the like including a cylindrical side wall, and intended for distribution in a selected region,

a generally circular lid having inner and outer faces for joining with and closing off one axial end of said side wall, and

means formed with said lid defining, on the outer face thereof, an arcuately distributed, electromagnetic-wave-readable code unique to such region including redemption-code information,

said code including code elements located along lines which generally radiate from the axis of revolution of said lid.

2. The container of claim 1, wherein said code elements are spaced angularly relative to one another in a pattern of presences and absences which embodies the coded information.

3. The container of claim 2, wherein said code elements are elongated and linear in nature.

4. The container of claims 1, 2 or 3, wherein said code elements take the form of axial depressions in said outer face.

5. The container of claims 1, 2 or 3, wherein said code elements take the form of axial projections from said outer face.

6. The container of claims 1, 2 or 3, wherein said code elements take the form of printing on said outer face, which printing has an electromagnetic-wave-reflectance characteristic which differs from that of adjacent areas on the outer face.

7. The container of claims 1, 2 or 3, wherein said code elements are arranged to form a binary-type code.

8. The container of claims 1, 2 or 3, wherein said code elements are arranged to form a frequency-type code.

9. The container of claims 1, 2 or 3 which further includes a second code-defining means, like said first-mentioned code-defining means, but located at a region displaced on the lid angularly from the latter for the purpose of affording code-reading redundancy.
