Abstract: De vinding betreft de fabricage van een fles in 2 elementen, welke op te verkiezen functionele hoogte een opendraalend segment kent, waardoor de fles zelve in 2 losse delen zich splitst, welke 2 segmenten om functionele redenen open en wederom tot één functioneel geheel waterdicht te draaien valt, naast de reguliere functionaliteit van de dop van het bovensegment. 1. Het systeem brengt een tweedeling teweeg om betere toegankelijkheid naar invoer van Ijsblokjes hetgeen het desgewenst effect in koeling opwaardeert, hetgeen met een "normale" fles niet mogelijk is (fig.l). 2. Het systeem brengt een tweedeling teweeg om betere toegankelijkheid naar invoer van schijfjes citroen hetgeen met een "normale" fles niet mogelijk is (fig.l). 3. Het systeem kan een toepassing zijn voor het koelen van een daartoe bestemde post-mix PET-bottle, wat opengedraaid voorzien kan worden van ijsblokjes om vervolgens, na het dichtdraaien met het bovensegment, gevuld te kunnen worden, zodat na voltooiing van dat proces de afsluitbare dop toegevoegd kan worden. 4. Aangezien dranken die meegenomen worden door mensen veelal gekoeld worden door koeltassen is deze vorm van koeling en instelling op additionele wensen middels de functionaliteit een welkome innovatie naar functionele duurzaamheid.
