Publication number: 20230090849Abstract: The invention relates to a closure consisting of a screw cap (10) with a tamperproof strip (3). The screw cap has at least one cylindrical cap casing (2) with an inner thread and a circumferential tamperproof strip at the lower open end of the cap casing, said tamperproof strip being connected to the lower edge of the cap casing along easily tearable weakness lines (13, 14), wherein the tamperproof strip remains captively connected to the cap casing after a tearing process along the weakness lines by means of holding strips (15, 16). The aim of the invention is to design a captive screw cap with a tamperproof strip in such a manner that after the screw cap has been unscrewed and released from the bottleneck opening, the screw cap is folded away or tilted into a position in which the screw cap does not interfere with the additional use of the bottle or with pouring or drinking out of the bottle and can remain there without additional measures.Type: ApplicationFiled: November 25, 2022Publication date: March 23, 2023Inventor: Gunter Krautkramer

Patent number: 11377271Abstract: The invention concerns a plastic closure part (10) which can be fixed to a container or a further closure part to be fixed to the container, comprising a tubular discharge portion (3) whose cross-section is closed by a membrane (7) which has a tear line (8) extending peripherally over more than 180° along its outer edge and a corresponding method for the production of such a closure. In order to develop a closure part having the features set forth in the opening part of this specification and a method for the production thereof to the effect that the problems occurring upon injection moulding due to narrow flow passages are eliminated it is provided according to the invention that the tear line (8) is formed by a cut introduced into the material of the membrane (7) with a cutting or punching tool.Type: GrantFiled: November 13, 2018Date of Patent: July 5, 2022Assignee: BERICAP Holding GmbHInventor: Günter Krautkrämer

Patent number: 11174078Abstract: Pouring closure for liquid containers with pour spout sealingly fixed to a container neck, the cross section of which is closed by a membrane before use. A portion of the membrane extends transversely, approximately pear-shaped, and connected to the remaining portion via an easily tearable line of weakness and can be detached from the membrane. After detachment, an opening in the membrane is released that is correspondingly pear-shape, and liquid poured selectively out of a relatively narrower section or wider section. The pouring closure is produced by tearing out a membrane section and facilitates dosed pouring. Webs on the inner surface at a close distance parallel to the line of weakness and outside the tear-out section run on both sides of the narrow section of the tear-out portion or of the opening and along at least a portion of a transition region between the narrower and the wider sections.Type: GrantFiled: December 13, 2017Date of Patent: November 16, 2021Assignee: BERICAP Holding GmbHInventor: Günter Krautkrämer
