Tamper-proofing European Award of Patent No.EP 2424789 B1 Applicant: Krones AG, Neutraubling (D) Application Date: 19.2.2010 A bottle made from glass or plastic is closed by means of a simplified screw closure which is secured by affixing a seal. When the lid is unscrewed this seal is irreversibly destroyed. This version permits dispensing with a guarantee strip which, in turn, results in a reduction in the material used. Bottom Section Moulding International Patent No.WO 2014 / 004919 A1 Applicant: Plastipak Packaging Inc., Plymouth (US) Application Date: 27.6.2013 In the interests of improving the appearance of a plastic bottle for carbonated products or those intended for hot fill- ing, compensation for the change in volume is undertaken from the bottom section. This needs to be specially moulded in order to do this so that it can absorb these forces elastically. This outside section of the bottle may be designed so that it incorporates a smooth surface.

Ltd., Tokyo (JP) Application Date: 12.11.2012 A bag is placed in a liquid container with carbonated contents. This bag releases carbonic acid over an extended period of time and thus keeps the product inside at a specific carbonic acid level. Dispensing cap International Patent No. WO 2014 / 005845 A1 Applicant: Obrist Closures Switzerland GmbH, Reinach (CH) Application Date: 20.06.2013 Dispensing cap optimised for products such as mustard, ketchup or similar which are capable of flowing.
