  • Patent number: 6241842
    Abstract: A transfer film for printing onto at least partially three-dimensional articles, with the intention that surfaces having different planar portions can be printed onto at the same time and with equally good effect, is partially cut into in the region of contour lines of the planar portions. The article printed onto is characterized by scarcely visible printing defects in marginal zones of the printing. Applications include any articles having raised planar portions, for example containers, rotary knobs etc.

  • Patent number: 5657870
    Abstract: A pack for stacked articles with at least an identical base area, for example rectangular or square, comprises two adhesive strips which do not have lines of weakness or tearing lines and are provided at least on the narrow sides of the stack. The material is recyclable and corresponds as far as possible to the other packaging material. A gripping aid facilitates the largely non-destructive pulling off of the adhesive strips for individually separating the articles. The pack can be used for all rectangularly shaped articles such as cuboids, cubes, disks etc.

  • Patent number: 5558275
    Abstract: An environmentally appropriate protective covering for articles, in particular rectangular parallelepipedal bodies, comprises a container receiving the article or rectangular parallelepipedal body, if appropriate is of a rectangular parallelepipedal form and is closed by means of an at least three-part, partly separable closure strip. For opening, the central part is separated from the side parts, which remain on the container. The presence or absence of the central part consequently represents an indication of originality. The closure strip can also be used advantageously in the case of a protective covering unit, comprising a plurality of stacked containers, for connecting and forming a pack. The invention can be used advantageously in any application where a single closure strip can be used to economize on outer packaging materials.
