The invention concerns a container comprising a container body of a material such as metal, PE or cardboard, having a primary opening which is closed by a metal plate portion acting as a first lid element, wherein the metal plate portion includes a lid tab which is defined by a separation line and which after being broken open opens a discharge opening, and the lid tab has an inclined surface co-operating with a first projection arranged on an opening means movable substantially parallel to the plate portion for applying a force to the lid tab in order to break open the separation line. In order to ensure that in such a container of the general kind set forth, a sufficiently high force can be provided for breaking open the plate portion at the separation line of the lid tab, it is proposed that a depressed bead (32) and adjacent thereto a raised bead (36) is provided at the lid tab (30), wherein the inclined surface is composed at least of a portion of a flank (33) of the depressed bead and at least a portion of a flank (37) of the raised bead. The invention further concerns a lid (20, 50) for such a container and a method of opening such a container (FIG. 4).
A container comprising a container body having a primary opening which is closed by a metal plate portion acting as a first lid element, wherein the metal plate portion includes a lid tab which is defined by a separation line and which after being broken open opens a discharge opening, and the lid tab has an inclined surface co-operating with a first projection arranged on an opening means movable substantially parallel to the plate portion for applying a force to the lid tab in order to break open the separation line, wherein the lid tab has a depressed bead and adjacent thereto a raised bead, wherein the inclined surface is composed at least of a portion of a flank of the depressed bead and at least a portion of a flank of the raised bead.
A container lid for a container comprising a container body of a material which is stable in respect of shape such as metal, PE or cardboard, which has a primary opening which is closed by a metal plate portion acting as a first lid element, wherein the metal plate portion includes a lid tab which is defined by a separation line and which after being broken open opens a discharge opening, and the lid tab has an inclined surface co-operating with a first projection arranged on an opening means movable substantially parallel to the plate portion for applying a force to the lid tab in order to break open the separation line, wherein the lid tab has a depressed bead and adjacent thereto a raised bead, wherein the inclined surface is composed at least of a portion of a flank of the depressed bead and at least a portion of a flank of the raised bead.
A method of opening a container comprising a container body of a material which is stable in respect of shape such as metal, PE or cardboard, having a primary opening which is closed by a metal plate portion as a first lid element, wherein in the opening operation for opening a discharge opening a separation line on the plate portion is broken open, which defines a lid tab, and for breaking open the separation line a first projection arranged on an opening means movable substantially parallel to the plate portion is guided along an inclined surface of the lid tab, whereby a force is produced on the lid tab, wherein the first projection in the opening operation is guided at least portion-wise along flanks of a depressed bead and a raised bead adjacent thereto.
