Ltd., Tokyo (JP) Application Date: 14.1.2009 A plastic bottle is equipped with surfaces facing inwards which, following hot filling and subsequent cooling, demonstrate fur- ther defined penetration into the inside so as to compensate for the negative pres- sure that develops. Container closure International Patent No. WO 2009 / 112752 A1 Applicant: Tetra Laval Holdings / Finance S.A., Pully (CH) Application Date: 24.2.2009 In this international patent application a number of options for improving the tamper-evident closure on a hinged lid are set out.

Bottle with handle International Patent No. WO 2011 / 017481 A2 Applicant: Robert Priessnitz, Dunellen (US) Date of Application: 5.8.2010 Children, the elderly or people with restricted movement in the hand find it difficult – particularly if there is an external build up of condensation – to hold a container of liquid securely and to pour out the contents. The design of this handle – moulding and integration in the neck area of the bottle – is aimed at minimising these problems. Plastic bottle International Patent No. WO 2011 / 016544 A1 Applicant: Dai Nippon Printing Co., Tokio (JP) Date of Application: 6.8.2010 The middle segment of a plastic bottle is specially moulded so as to elastically absorb any differences in pressure that may occur. Segments featuring a type of pre-tensioning can be “twisted“, thus compensating for the change in pressure by means of a change in volume.
