Abstract: A method for transcribing an odor or an aroma into a colorimetric description comprises: physico-chemical analysis of said odor or of said aroma in order to associate with it a physico-chemical description comprising a physico-chemical vector, comprising proportions associated with a predetermined set of respective volatile molecules; physico-chemical analysis of a set of so-called test odors and/or aromas in order to assign to each test odor or aroma of said set a so-called test physico-chemical description comprising a so-called test physico-chemical vector comprising test proportions associated with said predetermined set of respective volatile molecules; assigning to the test odors and/or aromas respective test colorimetric descriptions comprising so-called test proportions associated with a set of respective colors; assigning to the odor or to the aroma a colorimetric description comprising proportions associated with said respective colors.

Abstract: Pressurized gas injecting device (14) for a machine (1) for blow molding or stretch blow molding a container from a blank (2) of plastic material. The device has a nozzle (15) movable between an upper position separated from a mold (9) intended to receive the blank (2) and a lower position pressed against the mold (9) while covering a neck (3) of the blank (2); an insert (36) mounted movably with respect to the nozzle (15), the insert (36) having a lower end face (45) capable of being pressed against a lip (4) of the blank (2); and a return device (44) applying force on the insert (36) toward a lower position in which the insert (36) is at the end-of-travel stop with respect to the nozzle (15), and in which the lower end face (45) of the insert (36) extends beyond the nozzle (15).
