METHOD FOR THE PRODUCTION OF A SERIES OF CONTAINERS COMPRISING A STEP FOR MARKING CONTAINERS

The invention relates to a method for controlling a production facility of a series of containers from a series of preforms made of plastic materials. The method includes a first step of producing a preliminary series of individual containers from a preliminary series of preforms made of plastic materials. For each individual container produced during a tracking period, the method records (i) a marking that distinguishes said container other containers produced during said tracking period, and (ii) data relative to the production facility, its operation, and/or the preform or container. The method also includes a second step during which one or more physical values of each of the individually identified containers are measured during the first step, and a third step of compiling a database that matches, for each individually identified container, the measurement(s) of the second step, and the series of data acquired during the first step.

Articles comprising isosorbide and processes for their manufacture

The invention is generally directed to sports bottles and other articles produced by blow molding from polymeric materials containing isosorbide having glass transition temperatures ranging from 90° C. to 130° C., as well as to processes for producing them. These articles can be exposed to water at high temperatures and can be produced by using a suitable combination of a stretch ratio of less than 3× and a preform temperature at least 20° C. greater than the glass transition temperature (Tg) of the polymeric material.

METHOD FOR MANUFACTURING PLASTIC CONTAINERS BY BLOW MOLDING

Disclosed is a method for forming blanks made from plastic material into containers, the method including steps of blowing into the blanks in such a way as to form them into containers, then internally degassing the formed containers. In the method, the steps are carried out according to a first cycle at a first rate. Then, during a second subsequent cycle of steps carried out at a second rate slower than the first rate, a time delay is added with respect to the first cycle, during or after degassing, such that the second cycle lasts longer than the first.

Method and apparatus for sterilizing preform

To provide a method and an apparatus for sterilizing a preform that can reduce the amount of the remaining hydrogen peroxide in sterilization of a preform, a sterilizer at least containing 30% by mass or less of hydrogen peroxide and a solvent having a boiling point of 85° C. or lower is gasified, the sterilizer gas is blasted to the preform, and the preform to which the sterilizer has been blasted is heated to a temperature suitable for molding by blasting hot air or without blasting hot air.
