PAPER ARTICLE CONSISTING OF TWO OR MORE LAYERS |
摘要 |
The closures in known paper articles (1) are insufficient insofar as the closures can be opened and closed again unnoticed if handled cleverly. In the new paper article (1), any unauthorised opening attempt is to be subsequently readily recognisable. In the new paper article (1), the fibres of the layers (2, 3) of paper in the closure region (8) are offset relative to one another in such a way that they form a woven attachment (11) which inevitably tears when separated. <IMAGE> |
