Abstract
Abstract Containers, e.g. bottle crates, industrial containers, of a common issue (Fxx1), e.g. a manufacturing series, are provided with a specific marking which indicates that they belong together. The mixing up of the various issues (Fxx1 . . . Fyz1 . . . Fzz2) which occurs during the circulation (Z, RZ) can again be reversed in an automatic sorting process, which makes it possible to sort out a desired sub-quantity (Fxx1) and to subject same to a further process stage (Rxx1, Axx1). The marked containers display an optically readable marking (3, 4), from which the information for the automatic sorting out of an issue can be noted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
Method for sorting out containers, such as bottle crates and industrial containers, from a stock of containers by means of optical detection, which comprises: providing a stock of containers with specific markings from which it can be noted if they belong to a common issue, whereby after being mixed up during use the containers of a common issue are brought together; optically detecting said markings; separating containers from said stock based on the optical detection of containers belonging to a common issue; further checking the separated containers at a further processing stage for reuseable containers; and returning said reuseable containers to a more recent common issue, wherein the marking is changed before returning separated items to said more recent common issue.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
136 words
Device for the identification of a container, such as bottle crates and industrial containers, to be sorted out from a stock of containers by means of optical detection, which comprises a stock of containers with specific optically detectable markings from which it can be noted if they belong to a common issue whereby after being mixed up during use the containers of a common issue are brought together, characterized in that each container bears a marking identifying characteristics of the container wherein said marking is stamped into the material of the container as an integral part thereof during the manufacture thereof and the marking is such that it can be changed with regard to the information therein from a marking indicating an older date of manufacture to a marking indicating a more recent date of manufacture.
Claim 4
Dependent Claim
136 words
Device for the identification of a container, such as bottle crates and industrial containers, to be sorted out from a stock of containers by means of optical detection, which comprises a stock of containers with specific optically detectable markings from which it can be noted if they belong to a common issue whereby after being mixed up during use the containers of a common issue are brought together, characterized in that each container bears a marking identifying characteristics of the container wherein said marking is stamped into the material of the container as an integral part thereof during the manufacture thereof and the marking is such that it can be changed with regard to the information therein from a marking indicating an older date of manufacture to a marking indicating a more recent date of manufacture.
Claim 5
Dependent Claim
22 words
Device according to claim 2 wherein the marking consists of a series of optically readable perforations in the material of the container.
Claim 6
Dependent Claim
24 words
Device according to claim 2 wherein the marking consists of a plurality of optically readable, web-like raised parts in the surface of the container.
Claim 7
Dependent Claim
12 words
Device according to claim 4 wherein the marking is a multibar marking.
Claim 8
Dependent Claim
15 words
Device according to claim 5 wherein a marking bar comprises at least two height stages.
Claim 9
Dependent Claim
15 words
Device according to claim 5 wherein a marking bar comprises at least 3 height stages.
