| 摘要 |
The invention relates to a closing device (1) consisting of a plastic material for applying to a closed container consisting of a plastic film material. Only two cutting teeth (20, 21) of the same height are to be applied to the cylindrical perforator (5) of said device, said teeth being arranged in an angular region of between 70° and 120° of the circumference. In this way, the section of the subsequent tooth extends into the section of the previous tooth, enabling a secure opening, without the risk of cutting an entire rondelle out of the plastic film of the container. The creation of only two partial sections without producing an opening in the container is also prevented.
