A blow molded bottle (): a) which is self-collapsible during its emptying; b) which comprises at least two transversal grooves and/or ribs (), preferably located in the tubular body portion (), equipped with collapse starters (); c) wherein the mean wall thickness (Tmean) of the tubular body portion () is&#x2014;in an increasing order of preference&#x2014;less than or equal to 200; 180; 160; 150 &#x3bc;m; preferably comprised between 65 and 150; and more preferably comprised between 90 and 130 &#x3bc;m. The invention also discloses a method, a preform () and a mold for the manufacture of the aforementioned container by blow molding. The invention also discloses a method for bottling liquid into the bottles (), a method for dispensing the liquid, a dispenser for implementing the method and a method for packing the thin-walled bottles, in view of storage and transportation.

Self collapsible blow moulded plastic thin-walled containers and a dispensing method using same

A preform, which makes it possible to obtain PEF containers (bottles) having the awaited properties, notably mechanical, by an industrial injection stretch blow molding process, is of made of a thermoplastic PEF polymer of 2,5-FuranDiCarboxylic Acid (2,5-FDCA) monomer and monoethylene glycol (MEG) monomer and comprises a neck end, a neck support ring, and a closed tubular body portion. The preform is designed so as to produce, by injection stretch blow-molding, a container, the axial stretch ratio of which is greater than or equal to its hoop stretch ratio. Also provided is a plastic container, preferably a bottle, obtained by injection stretch blow-molding of PEF preform, the bottlehaving an axial stretch ratio greater than or equal to the hoop stretch ratio. A method for manufacturing the bottleis also provided.
