The side wall, extending below a shoulder of the thermoplastic bottle, has a gripping portion formed substantially in the middle of the bottle body and includes a first line and a second line each defined in a vertical symmetry plane. The second line has a second point at minimal distance ds2 between the side wall and the central axis, while the first line has a first point at minimal distance dsl between the first line and the central axis. For these particular points in the gripping portion: &#xb7;ds2&#x3c;ds1&#xb7;hs1&#x3c;hs2 A thick portion is provided at and above the second point.

Plastic bottle with an annular gripping portion

The liquid filled bottle includes a plastic bottle () and a cover member (C) sealing an opening () of the bottle, the cover member (C) including: &#x2014;a closing portion () sealing the opening () of the bottle () in an annular area (), the closing portion having a circumference () defined by an outer edge of the annular area, the closing portion defining a first surface (S) that is substantially planar and delimited by the circumference; and &#x2014;a label portion () that defines a second surface (S), the label portion () and the closing portion () being parts of a single piece foil, for instance a flexible plastic foil. The second surface (S) is entirely offset relative to the annular area (), the ratio between the second surface (S) and the first surface (S) being at least 1:2, and preferably at least 1:1.

Liquid filled bottle having a cover member with a label forming extension

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.

Preform and method for the manufacture of a PEF container using said preform by injection stretch blow-molding

An injecting/blowing device includes a mold for injecting a thin-walled hollow preform capable of being transformed into a more voluminous hollow body. The mold includes a counter mold defining a cavity, a cure located in the cavity, and a preform impression located between the counter mold inner surface and the core which will receive the melt, at least two main preferential flow channels or at least two secondary preferential flow channels having a recessed zone at the surface of the core and the inner surface of the cavity. The main flow channels are located only at the impression zone corresponding to the zone for transforming the perform, and in the optional secondary flow channels are flow channels discontinuous from the main flow channel.

Process for injection molding of thin-walled preform

The invention concerns an injecting/blowing device comprising at least one mold for injecting a thin-walled hollow preform capable of being transformed into a more voluminous hollow body by blowing, said mold including a counter mold defining the inner surface of the cavity, a cure located in the cavity and spaced apart from said inner surface, a preform impression located between the counter mold inner surface and the core, and which will receive the melt, at least two main preferential flow channels (CEP) optionally at least two secondary preferential flow channels (CEP), each CEP being delimited by at least one recessed zone at the surface of the core and the inner surface of the cavity. Said device is characterized in that: the main CEP are located only at the impression zone corresponding to the zone for transforming the preform; and in that the optional secondary CEP are discontinuous, distinct from the main CEP, and located at the impression zone corresponding to the base and/or the body and/or the ring of the preform.
