Definitions

  • the present invention generally relates to the field of liquid food containers, and particularly relates to a preferably thin-walled bottle collar (typically made of plastic) which contains a liquid food such as non-carbonated mineral water.
  • the invention also relates to an object or an apparatus which can be coupled with the bottle.

  • it may be necessary to provide reliable orientation, and/or a possibility of recognizing that the bottle is a genuine bottle . . . and these functions may require on the bottle mechanical actions or contacts which must be safe and repeatable, in particular by a variety of users.
  • One aim of the present invention is to overcome the drawbacks of the documents of the prior art mentioned above and particularly, first of all, to propose a bottle collar which is easy and inexpensive to manufacture, while offering a capacity of facilitated, reliable and repeatable coupling with an object or an apparatus, in particular by a user.

  • the protuberance 27 is adjacent to the shoulder 28 of the bottle 20 , so that the wall of the shell 10 at the level of the flange 11 or of the shell shoulder 16 cannot slip between the shoulder 28 and the protuberance 27 of the bottle 20 .
  • the rotational stop and stop position are well controlled.
  • FIG. 8 shows a front view of the bottle 20 and of the protuberance 27 .
  • the flange 22 has a diameter D 3
  • the collar under the flange has for its part a diameter D 4 less than D 3 , over a height X 1 of 2.5 mm at least, and over 360°.
  • a gripping by a clamp is possible under the flange 22 , even in the presence of the protuberance 27 .
  • the protuberance 27 has a width smaller than the value of the diameter D 4 under the flange, so that it is possible to guide the bottle 20 during the manufacture via rails which bear under the flange 22 .
  • FIG. 5 which shows the bottle 20 from the side
  • the protuberance has a radial dimension similar to that of the flange 20 and that it does not protrude.
  • FIG. 9 which shows the bottle 20 in section along a plane normal to the axial direction of the bottle and passing between the protuberance 27 and the flange 22
  • the radial dimension A 3 of the protuberance 27 is substantially equal to D 3 / 2 .
  • the rest of the collar has a radial dimension A 2 smaller than A 3 .
  • FIG. 9 also shows that the protuberance 27 extends along an angular sector A 1 , with a value of approximately 90° here, but values between 30 and 150° can for example be envisaged.
  • a strap or a wrist strap or textile loop and hook fastener strips can also be provided to allow the consumer to transport the object 30 in various activities (sport, hiking, etc.). It is also possible to provide for one or several grips on the shell 10 .
  • the bottle 20 , the collar and/or the body of the bottle is preferably formed from a preferably thin-walled thermoplastic material.
  • the material is preferably a polyester such as polyethylene terephthalate (PET), poly-trimethylene terephthalate (PTT), polyethylene furanoate (PEF) or poly-trimethylene furanoate (PTF).
  • PET polyethylene terephthalate
  • PTT poly-trimethylene terephthalate
  • PET polyethylene furanoate
  • PEF poly-trimethylene furanoate
  • PPF poly-trimethylene furanoate
  • the material can be an at least partially recycled material.
  • the bottle is preferably shaped by an Injection Blow Molding process, for example an Injection Stretch Blow Molding process. In these processes, a solid preform (represented in FIG.
  • the preform 10 is manufactured by injection of the material into a mold and then by cooling, the preform is then heated in order to soften it, optionally stretched longitudinally using a rod, then stretched axially and longitudinally by blow molding in a mold in the shape of the bottle.
  • polyester materials and methods are known to those skilled in the art. Their combination allows obtaining 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 sectors are organized.
  • the regeneration can be a mechanical recycling involving melting and shaping, for example into granules prior to new plastics processing operations such as the injection blow molding or chemical recycling involving depolymerization, recovery of monomers or precursors, then a new polymerization.
  • the thin wall is preferably such that the body of the bottle has a thickness within a range from 30 ⁇ m to 150 ⁇ m, for example in a range from 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 from 100 ⁇ m to 125 ⁇ m.
  • the thickness mentioned is the thickness at least at one point of the body, preferably the average thickness over a portion representing at least 50% in length or in surface of the body, preferably at least 80%, preferably the average thickness over the whole body.
  • the bottom of the bottle can be slightly thicker than the body, for example up to 50% thicker than the body, for example up to 20% thicker.
  • the bottom can also have a cup typically corresponding to the bottom of the preform and at 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 stretching 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 determine, together with the collar that may form a bottle neck, the weight.
  • the unfilled, unclosed bottle and/or the preform generally have an identical weight. Subsequently, the weights given refer either to the bottle weights or to the preform weights. For a 75 cl bottle, it is advantageously possible to implement preforms from 8 to 13 g.
  • the overall stretching rate can for example be comprised between 12.0 and 27.0, preferably between 15.0 and 20.0.
  • the axial stretching 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 collar) can for example be comprised between 3.0 and 4.5.
  • the radial stretching rate (typically ratio between the diameter of the bottle and the diameter of the stretchable part of the preform) can for example be comprised between 4.0 and 6.0. It is mentioned that the overall stretching rate is generally equal to the product of the axial stretching rate and of the radial stretching rate.
  • FIG. 10 represents a preform 40 produced by injection and which can be used in a blow molding process to produce the bottle 20 of FIG. 4 .
  • the preform 40 has a threaded upper part CF which will not be stretched during the blow molding process and which therefore has the same dimensions as the collar of the bottle 20 .
  • the presence of the flange 22 which is of the same dimensions as that of the bottle 20 can be noted.
  • a cylindrical part separates the flange 22 from a slightly tapered part Ep, adjacent to a lower part Co of the preform.
  • the part Ep of the preform approximately corresponds to the shoulder 28 of the bottle 20
  • the part Co approximately corresponds to the side wall 24 and to the bottom 25 of the bottle 29 . It is important to note that the cylindrical area between the part Ep and the flange 22 of the preform 40 is free of bosses or protuberances. Indeed, the protuberance 27 will be formed during the blow molding operation in this exemplary embodiment.
  • the preform 40 or 40 A can be formed in a thermoplastic material, and it can have:
  • a protuberance 27 arranged under the flange 22 and adjacent to the shoulder 28 of the bottle allows reliably coupling the bottle 20 to a shell 10 .
  • the protuberance 27 can be used in order to:
  • the protuberance 27 can be used in order to:
  • the protuberance 27 can also be used to bear a marking, a logo for example in order to provide traceability or indication of material for a particular recycling in the case of specific material.
  • the protuberance 27 can itself be used as a marking for example in order to provide traceability or indication of material for a particular recycling in the case of specific material.
