Closure cap and container neck for preventing detachment of a tamperevident strip

A closure cap, comprising:

• a lid portion and a cap skirt,
• wherein the cap skirt comprises an inner thread and defines a closure axis such that the closure cap can be screwed onto an outer thread of a container neck,
• wherein a circumferential security band is arranged on an edge of the cap skirt facing away from the lid portion and connected to the cap skirt via multiple tearable bridges,
• wherein at least one latching element is arranged on the inner side of the security band,
• wherein the latching element extends inwardly from the security band,
• wherein the latching element comprises a first stop surface having a surface normal arranged at least proportionally tangentially to the cap skirt, such that, in an assembled state of the closure cap and a container comprising the container neck, the first stop surface can be brought into engagement with a first stop surface of the container neck,
• wherein, by the engagement of the two first stop surfaces, a holding torque acting counter to an opening direction of the closure cap is applied to the security band when the closure cap is initially rotated in the opening direction,
• wherein a blocking element is arranged on the security band,
• wherein the blocking element comprises a second stop surface having a surface normal facing at least proportionally in the axial direction, such that, in an assembled state of the closure cap and a container, the second stop surface can be brought into engagement with a second stop surface of the container neck,
• wherein, by the engagement of the two second stop surfaces, a holding force acting in the axial direction is applied to the security band when the container is tilted for pouring a filling material.

A container having a container neck,

• wherein the container neck defines a container neck axis and comprises a pouring opening and an outer thread for receiving a closure cap having an inner thread,
• wherein at least one latching element is arranged on the container neck on a side of the outer thread facing away from the pouring opening,
• wherein the latching element extends outwardly from the container neck,
• wherein the latching element comprises a first stop surface having a surface normal arranged at least proportionally tangentially to the container neck, such that, in an assembled state of the container and a closure cap, the first stop surface can be brought into engagement with a first stop surface of the closure cap,
• wherein, by the engagement of the two first stop surfaces, a holding torque acting counter to an opening direction of the closure cap is applied to the first stop surface of the closure cap when the closure cap is initially rotated in the opening direction,
• wherein a blocking element is arranged on the container neck,
• wherein the blocking element comprises a second stop surface having a surface normal facing at least proportionally in the axial direction, such that, in an assembled state of the container and the closure cap, the second stop surface can be brought into engagement with a second stop surface of the closure cap,
• wherein, by the engagement of the two second stop surfaces, a holding force acting in the axial direction is applied to the second stop surface of the closure cap when the container is tilted for pouring a filling material.

A combination of a closure cap and a container,

• wherein the closure cap comprises a lid portion and a cap skirt having an inner thread and the container comprises a container neck having an outer thread, such that the closure cap can be screwed onto the outer thread of the container neck,
• wherein the cap skirt defines a closure axis and the container neck defines a container axis, wherein the closure axis and the container neck axis are coextensive in the assembled state of the closure cap and container,
• wherein a circumferential security band is arranged on an edge of the cap skirt facing away from the lid portion and connected to the cap skirt via multiple tearable bridges,
• wherein at least one latching element is arranged on the inner side of the security band,
• wherein at least one further latching element is arranged on the container neck on a side of the outer thread facing away from the pouring opening,
• wherein the latching element of the closure cap and the latching element of the container neck are configured and arranged such that, in an assembled state of the closure cap and container, a first stop surface of the latching element of the closure cap can be brought into engagement with a first stop surface of the latching element of the container,
• wherein, by the engagement of the two first stop surfaces, a holding force acting counter to the opening direction of the closure cap is applied to the security band when the closure cap is initially rotated in the opening direction,
• wherein a blocking element is arranged on the security band and a blocking element is arranged on the container neck,
• wherein the blocking element of the closure cap and the blocking element of the container are configured and arranged such that, in an assembled state of the closure cap and container, a second stop surface of the blocking element of the closure cap can be brought into engagement with a second stop surface of the blocking element arranged on the container neck,
• wherein, by the engagement of the two second stop surfaces a holding force acting in the direction of the closure and container neck axis is applied to the security band when the container is tilted for pouring a filling material.
