A closing cap made of plastic for closing a container, having a head part and a jacket part, the jacket is substantially shaped like a hollow cylinder and has a longitudinal axis, the jacket extends from the head along the longitudinal axis, the jacket has an end segment at the end opposite the head. The closing cap has a tamper-evident part and bridge parts, wherein the tamper-evident part is arranged at a distance from the jacket and is connected to the end segment of the jacket by bridge parts. Additionally the tamper-evident part is arranged in the direction of extension of the longitudinal axis along the end segment, such that the tamper-evident part is arranged at a distance from the jacket in a direction radial to the longitudinal axis and extends in a circumferential direction to the longitudinal axis on the outside along the jacket.
A tamper-evident closure comprising a closing cap made of plastic and a container neck,
A container neck having a pour channel which extends in the direction of a longitudinal axis and which opens into an outlet opening, wherein the container neck has, toward the outlet opening, a front portion and, adjoining the front portion in the direction of the longitudinal axis, a rear portion, and wherein the container neck has, on the outside of the front portion, an outer thread or an engagement means for securing a closing cap, wherein the outer thread or the engagement means has a depth radial to the longitudinal axis, and wherein the container neck has, in the rear portion, a connection site and an engagement part, wherein the connection site extends radially with respect to the longitudinal axis, and wherein the engagement part, starting from the connection site, extends in the direction of the longitudinal axis and toward the outlet opening, and wherein the container neck has a support part which is arranged opposite the engagement part, such that a gap extending in the direction of the longitudinal axis forms between the support part and the engagement part, and wherein the support part has a width, radial to the longitudinal axis, which width is at least as great as the depth.
A method for producing a tamper-evident closure by connecting a closing cap to a container neck having a pour channel which extends in a direction of a longitudinal axis and which opens into an outlet opening, wherein container neck has, toward the outlet opening, a front portion and, adjoining the front portion in the direction of the longitudinal axis, a rear portion, and wherein the container neck has, on the outside of the front portion, an outer thread or an engagement means for securing a closing cap, wherein the outer thread or the engagement means has a depth radial to the longitudinal axis, and wherein the container neck has, in the rear portion, a connection site and an engagement part, wherein the connection site extends radially with respect to the longitudinal axis, and wherein the engagement part, starting from the connection site, extends in the direction of the longitudinal axis and toward the outlet opening, and wherein the container neck has a support part which is arranged opposite the engagement part, such that a gap extending in the direction of the longitudinal axis forms between the support part and the engagement part, and wherein the support part has a width, radial to the longitudinal axis, which width is at least as great as the depth, the method comprising:
