US Patent 11059638 Container

A container has an at least partially filled container body and at least one cap part (10). The cap part has at least one sealing part (16) that, for removal of the container contents, can be penetrated by a hollow-spike-shaped insertion part (22) from the outside, with a predeterminable actuating force, in an introduction direction. The insertion part can be removed from the container again, with a predeterminable pull-out force, in an oppositely directed pull-out direction. A device (16, 18) makes it difficult for the insertion part (22) to be removed with the pull-out force being increased such that unintentional removal of the insertion part (22) is at least made difficult.
