KG, Hard (AT) Registration date: 02/15/2014 An improved method for making a container using the stretch blow-moulding process is described. The support ring inte- grated into the preform is “reused” as part of the container shoulder and is in close proximity to it. This allows for a more attractive container and closure design. Destruction of product capsules European Patent No.EP 2749502 A1 Applicant: Colgate-Palmolive Comp., New York (US) Date of Application: 21.4.2011 A disc similar to a filter with sharp edges is inserted into the neck of a container which stimulates/destroys the capsules inside the product that contain a second product. The two products are mixed together shortly before use and are able to react with one another. Bottom section mould European Patent No.EP 2752369 A1 Applicant: Yoshino Kogyosho Co. Ltd., Tokyo (JP) Date of Application: 29.8.2012 The shape of the bottom section of a hot fill bottle or a bottle containing carbonates needs to be specially designed and by definition capable of elastic deformation so as to be able to absorb differences in pressure without having a negative effect on the stability or external shape of the bottle. Pressure compensation opening European Patent No.EP 2752370 A1 Applicant: Yoshino Kogyosho Co. Ltd., Tokyo (JP) Date of Application: 8.8.2012 Multi-layer plastic bottle and process for manufacturing the said bottle inclusive of the insertion of an opening for pressure compensation (to allow air to flow in) in the neck area. As air flows in, one layer of plastic is delami- nated and the product cham- ber formed by the internal layer is reduced in volume. Foam dispenser European Patent No.EP 2752374 A1 Applicant: Yoshino Kogyosho Co. Ltd., Tokyo (JP) Date of Application: 21.8.2012 Squeezable container for absorbing a liquid. Pressure on the container and a corresponding dispensing device gener- ate a foam on output. Anti-drip closure International Patent No. WO 2013 / 041716 A1 Applicant: Maitrise & Innovation, Val de Reuil (FR) Date of Application: 24.9.2012 Structure and operation of an improved closure for a squeezable container. As a result of manual pressure on the container and thus on the product, the closure is opened and, when pressure is removed, is resealed so that it is once again tight and ”drip-free“.
