The bottom is “thicker” and fitted with reinforcing ribs at precisely those points where increased stiff- ness and/or stability are required. Double sealing membrane International Patent No. WO 2014 / 170215 A1 Applicant: S.A. des Eaux Minerales d’Evian SAEME, Evian-les-Bains (FR) Date of Application: 10.4.2014 The application proposes seal- ing a bottle made from PET with a foil and a reinforcement ring instead of a cap or screw closure. This enables savings in materials to be made as a result of omitting thread and screw closures. Bottom shape for hot filling International Patent No. WO 2014 / 170115 A1 Applicant: Krones AG, Neutraubling (DE) Date of Application: 28.3.2014 Plastic bottle that is designed and shaped for hot filling but at the same time takes into account the requirements of the marketing department for “not too high” shaped bottom so as to be pleasing to the eye and enabling attractive label- ling to be attached. Rapid action closure Disclosure No. DE 102013007664 A1 Applicant: Helmut Obieglo, Düsseldorf (DE) Application date: 6.5.2013 The threads on the bottle and on the closure incorporate recesses to ensure rapid, problem-free fitting of the closure and sealing of the bottle. The closure is fitted and a minimum angle of rotation deployed to seal the bottle tightly. Handles for PET containers International Patent No. WO 2014 / 207614 A1 Applicant: René Wilhelm, Lütisburg (CH) Application date: 18.6.2014 Thin-walled and high volume PET bot- tles are inclined to become unstable or collapse as the fill quantity decreases. In the interests of improved handling, the use of a separately fabricated plastic strip attached to the container by sticking or welding or by means of a sleeve is pro- posed. This indirectly serves as a handle for grasping and holding the bottle. Lightweight container European Award of Patent No.EP 2582584 B1 Applicant: Sidel Participations, Octeville sur Mer (FR) Application date: 15.6.2011 A reduced weight plastic bottle made from PET with a rein- forced bottom section is being awarded a European patent. The base section incorporates grooves aimed at maintain- ing adequate stability despite reduced wall thickness.
