Abstract: A container, in particular in ampoule form, and consists entirely or predominantly of plastic materials and has a container body (10) for receiving a filling product (12). The filling product can be removed via a releasable container opening (22) after a closure part (18) has been removed, which closure part is detachably connected to the neck part (14) of the container body (10) along a separation line (20) in an unopened position. In the unopened position, a conically extending wall (36) on the neck part (14) on the container body (10) and a conically (38) or cylindrically extending wall (38a) on the closure part (18) adjoin the separation line (20). These walls (36, 38, 38a) delimit at least part of an annular space (40, 40a), one end of which opens out into the environment and the other end of which opens out into the separation line (20).

Abstract: A container, in particular an ampule, of a plastic material has a container part (10) for receiving the contents of a container (14) to be dispensed via a container opening (12). Opening (12) is closed by a head part (18) that can be separated along a separation line (16). The head part (18) is adjoined by a neck part (20), which has a plurality of different functional surfaces on the inner circumference. One functional contact surface (44) is used to seal against a withdrawal body (32), which is provided for withdrawing the contents of a container (14) when the container opening (12) is opened. A lead-in area (50) is provided as a further functional surface on the interior of the neck part (40) and differs geometrically from the functional contact surface (44). The lead-in area (50) seamlessly merges into the functional contact surface (44). The lead-in area (50) and the functional contact surface are located between the other functional surfaces in the neck part (20).
