- the protuberance has a second angular dimension relative to the axial direction of the object, less than the first angular dimension. The presence of the protuberance does not disturb the opening of the upper neck of the shell and does not compromise the elastic interlocking.
- the bottle has a concave bottom, for example hemispherical
- the shell has a bottom defining at least one flat support for placing the object in a vertical position.
- the flat or flat bottom makes it possible to provide a stable vertical support, although the bottle alone, with a thin wall, therefore flexible by definition, and whose bottom is hemispherical in shape, cannot be placed and held vertically on a work surface.
- the shell has an external diameter
- the bottom of the shell comprises at least one flat crown (that is to say contained in a plane), or supports distributed along a flat crown (that is to say contained in a plane), the plane crown having a diameter greater than or equal to 50% of the external diameter.

- wall or cylindrical part is meant a portion of the shell or bottle which has a lateral surface whose generatrices are parallel straight lines, and which follow a base curve (defined by the intersection of the lateral surface with a plane perpendicular to a axial direction of the bottle) which is a closed curve.
- This closed base curve can be circular (a circle), oval (an ellipse or any oval), square or rectangular, where appropriate with rounded corners.
- the bottle is formed from polyethylene terephthalate (PET).
- the bottle has an internal volume:
- the upper neck of the shell has an upper rim, and the upper rim is formed over more than 180 ° relative to an axial direction of the object.
- more than half of the perimeter of the neck of the bottle is received and held by the open top neck of the shell, which provides an effective hold.
- the upper rim is included in a plane.

- FIG 10 shows a second view of the alternative shell of Fig. 8, with a sketch of a mated cylinder.
- Figures 1 to 3 show a shell 10 seen from different directions.
- the shell 10 comprises an upper neck 11, a side wall 15, a bottom 14 and a shoulder 16 arranged between the upper neck 11 and the side wall 15.
- the side wall 15 is cylindrical or substantially cylindrical (that is to say that its outer surface comprises parallel straight generatrices which follow a base curve, here a circle).
- the bottom 14 has a lower plate, which allows to put the shell 10 in a vertical position, as will be discussed in Figure 7.
- the shell 10 comprises a passage opening 12 mainly visible in Figures 1 and 3, arranged in the shoulder 16, and an introduction opening 13, mainly visible in Figure 2.
- the upper neck 11 is an open neck in the form of a C (or U), as shown in Figures 1 and 3.
- the upper neck 11 has a passage dimension D2 according to its largest internal diameter, and a passage dimension D'2 at its opening.
- the opening of the upper neck 11 (of dimension D'2) gives or opens into the passage opening 12, and it can be noted that the passage dimension D1 of the passage opening 12 is greater than the passage dimensions D2 and D'2 of the upper neck 11.
- Figures 4 and 5 show a bottle 20 which comprises a neck 21 (or neck), a side wall 24 and a bottom 25.
- the neck 21 is threaded to receive a cap 26 (visible figure 6), and a collar 22 is provided under the thread, and a protuberance 27 is arranged under the collar 22.
- the bottle 20 also contains a liquid food (non-carbonated mineral water for example).
- FIG. 5 represents an external dimension D3 of the flange 22, and this external dimension D3 is less than the passage dimension D1 of the passage opening 12 of the shell 10, but greater than the passage dimension D2 or D'2 of the upper neck 11 of the shell 10.
- the shell 10 and the bottle 20 can mate and be held together.
- the upper neck 11 of the shell 10 is designed to fit elastically with the neck 21 of the bottle 20.
- the upper neck 11 of the shell 10 has dimensions adapted to fit elastically on the bottle 20, under the collar 22.
- the upper neck 11 of the shell 10 is formed over more than 180 ° (for example 270 °, at ⁇ 45 °) so as to be able to move away , receive and retain the neck 21 of the bottle 20, in particular by retaining the collar 22.
- the upper neck 11 of the shell has a cylindrical rim of a few millimeters
- the bottle 20 comprises the collar 20, and a cylindrical neck portion arranged between the collar 22 and the shoulder of the bottle 20, and the cylindrical rim of the upper neck 11 clamps the cylindrical neck portion of the bottle 20, while coming into axial abutment with the flange 22, which provides an assembly of the shell 10 and the bottle 20.
- the shell 10 and the bottle 20 form an object 30 easy to handle for a user.
- the bottom 14 of the shell 10 is flat, so that the object 30 holds a stable vertical position when it is placed on a work surface.
- a return 16 is provided on the lower part of the shell 10 to secure the coupling and the holding of the bottle 20 - shell 10 assembly.
- the cap 26 is screwed on the bottle 20.
- a protuberance 27 is provided on the bottle 20 to come to be housed in the opening of the upper neck 11 of the shell 10.
- a torque applied to the bottle 20 is transmitted to the shell 10 via the protuberance 27.
- indexing as by example a neck 21 of the bottle 20 with a non-circular section, crenellations at the level of the upper neck 11 which engage in counter-shapes of the collar 22 ...
- the shell 10A comprises in particular two side edges 17 and 18 connecting the bottom to the shoulder, as seen in Figures 8 and 9.
- first side edge 17 is curved or curved towards the outside
- second lateral edge 18 is rather straight or rectilinear.
- Such an arrangement makes it possible to provide an integrated handle once the bottle 20 is coupled to the shell 10A.
- the first side edge 17 is distant from the bottle 20, so that a gripping space between the first side edge 17 and the bottle 20 is offered to the user, and forms a handle P.
- the second lateral edge 18 for its part follows the bottle 20 and provides a support which prevents it from coming apart.
- the user can easily grasp the object thus formed, via the first lateral edge 17.
- Such an implementation is economical and however offers a reliable coupling between the shell 10A and cylinder 20.
- the bottle 20 is formed from a thermoplastic material with thin walls.
- the material is preferably a polyester such as polyethylene terephthalate (PET), poly-trimethylene terephthalate (PTT), polyethylene furanoate (PEF) or poly-trimethylene furanoate (PTF). It is preferably shaped by an injection blow molding process (“Injection Blow Molding” in English), for example an injection stretch blow molding process (“Injection Stretch Blow Molding”). In these processes a solid preform is manufactured by injecting the material into a mold and then cooling, the preform is then heated in order to soften, optionally stretched longitudinally using a rod, then stretched axially and longitudinally by blowing in a mold in the form of the bottle.
- injection blow molding process injection blow molding process
- injection Stretch Blow Molding injection stretch blow molding process
- polyester materials and methods are known to those skilled in the art. Their combination makes it possible to obtain thin, light walls, with good mechanical resistance and good sealing or other barrier properties. These properties are due to the orientation of the macromolecular chains, at least partially inducing crystallization.
- these polyesters have the advantage of being easily recyclable.
- the recovery, sorting and regeneration channels are organized. Regeneration can be mechanical recycling involving melting and shaping, for example into granules before new plastics processing operations such as injection blowing or chemical recycling involving depolymerization, recovery of monomers or precursors, then a new polymerization.
- the implementation and use of the thin-walled bottles of the invention therefore has a very advantageous environmental balance, in addition to good practicality, in particular by contribution to the implementation of conventional PET bottles non-activatable, thicker.
- the thin wall is preferably such that the body of the bottle has a thickness within a range of 30 ⁇ m to 150 ⁇ m, for example in a range of 30 ⁇ m to 50 ⁇ m or from 50 ⁇ m to 70 ⁇ m or from 70 ⁇ m to 100 ⁇ m, or from 100 ⁇ m to 125 ⁇ m or from 125 ⁇ m to 150 ⁇ m, preferably in a range of 100 ⁇ m to 125 ⁇ m.
- the thickness mentioned is the thickness at at least one point of the body, preferably the average thickness over a portion representing at least 50% in length or area of the body, preferably at least 80%, preferably the thickness average over the whole body.
- the bottom of the bottle can have a thickness slightly greater than that of the body, for example a thickness of up to 50% more than that of the body, for example up to 20% more.
- the bottom may also have a cup, typically corresponding to the bottom of the preform and to its injection point.
- the thickness can be adjusted by adapting, for a target bottle volume, the characteristics of the preform, in particular its shape and the thickness of its walls, as well as the drawing characteristics. It is mentioned that the thickness of the preform walls, the geometry of the preform such as its length, its diameter and its bottom shape, together with the neck which may form a bottle neck, determine the weight. The bottle, unfilled, not closed, and / or the preform generally have the same weight. Subsequently, the weights given refer to either the bottle weight or the preform weight. For a 75 cl bottle, it is advantageously possible to use preforms of 8 to 13 g.
- the overall stretch ratio may for example be between 12.0 and 27.0, preferably between 15.0 and 20.0.
- the axial stretch rate (typically the ratio between the height of the bottle and the length of the stretchable part of the preform, typically the distance under the neck) can for example be between 3.0 and 4.5.
- the radial stretch rate (typically ratio between the diameter of the bottle and the diameter of the stretchable part of the preform) can for example be between 4.0 and 6.0. It is stated that the overall stretch rate is generally equal to the product of the axial stretch rate and the radial stretch rate.
