Definitions

  • the invention relates to the manufacture of containers, such as bottles or pots, obtained by blow molding or stretch blow molding from thermoplastic preforms.
  • heat setting Frnch translation of the English expression "heat set”
  • Heat-setting only solves a part of the container deformation problems related to hot filling. Indeed, while cooling, the liquid and the air which overhangs it in the clogged container undergo a decrease in volume which tends to retract the container.
  • an object of the invention is to improve the mechanical and / or aesthetic properties of containers for use in hot filling.
  • the bottom comprises ribs, preferably having a V-shaped cross-section and extending at least partly radially and projecting from the membrane towards the inside of the container.
  • the bottom may comprise a bearing extending from the step, and a riser extending from the bearing and in which the ribs are anchored at an outer end.
  • the ribs may extend radially or have two radial sections connected by a curved intermediate section.
  • the bottom may further comprise a central rib, preferably having a V-section in section and dividing the membrane into two parts, namely a central portion surrounding the pin and a peripheral portion surrounding the central portion.
  • the ribs protrude over the peripheral portion of the membrane; they can be anchored in the central rib, or tangent to it.
  • the membrane may have, before filling, a concavity facing inwardly or on the contrary towards the outside of the container. Its radius of curvature is preferably between 50 mm and 150 mm. This radius of curvature is for example about 100 mm.
  • the container may be heat set.
  • a container 1 - in this case a wide-necked bottle, with a capacity of about 0.6 l - produced by stretch-blow molding from a thermoplastic preform such as PET (polyethylene terephthalate).
  • PET polyethylene terephthalate
  • This container 1 comprises, at an upper end, a threaded neck 2 , provided with a rim 3.
  • the container 1 comprises in its upper part a shoulder 4 flaring in the direction opposite to the neck 2, this shoulder 4 being extended by a side wall or body 5, of generally cylindrical shape of revolution about a main axis X of the container 1.
  • the body 5 comprises a succession of stiffeners 6 in the form of annular beads separated in pairs by annular grooves 7 .
  • some grooves 7a located near the shoulder 4 (in this case the two grooves 7a closest to the shoulder 4 ) have a V-shaped profile to provide the container 1 of the radial stiffness while allowing axial retraction of the latter in this region, while the following grooves 7b , in the central part of the container 1 and in its lower part, have a flat bottom U-shaped profile to provide the container 1 a stiffness that is both axial and radial.
  • the container 1 further comprises a bottom 8 which extends to a lower end of the container 1.
  • the bottom 8 comprises an annular base 9 , through which the container 1 can rest stably on a flat surface (such as a table ) and which extends substantially perpendicular to the body 5 (or to the axis X of the container) in the extension thereof.
  • the bottom 8 also comprises an annular step 10 , which extends from the base 9, in the extension thereof towards the inside of the container 1.
  • the step 10 is preferably frustoconical; the angle at the top of this step is between 30 ° and 90 °.
  • the bottom 8 further comprises an annular membrane 11 , which extends in the extension of the step 10 towards the axis of the container 1, substantially perpendicular to the body 5 (or the X axis ).
  • the bottom 8 finally comprises, at its center and in the extension of the membrane 11, a central pin 12 which projects inwards towards the container 1.
  • the membrane 11 has, at the junction with the step 10, a circular outer edge 13 , and at the junction with the pin 12, a circular inner edge 14 .
  • the membrane 11 is, before hot filling of the container 1, concave concavity turned inwardly thereof.
  • the inner edge 14 of the membrane 11 appears to be situated below the outer edge 13 - without, however, that the inner edge 14 exceeds the plane of the base 9.
  • the membrane 11 is, before the hot filling of the container 1, convex, that is to say that its concavity is turned towards the outside of the container 1.
  • the inner edge 14 of the membrane 11 appears located above the outer edge 13 .
  • the membrane 11 is preferably in the form of a spherical cap, of symmetry of revolution about the main axis X of the container and whose radius of curvature is between 50 mm and 150 mm.
  • spherical cap here refers to a curved surface, for which the radius of curvature is substantially continuous, that is to say that the concavity does not change on the surface.
  • the radius of curvature of the membrane 11 is preferably between 60 and 80 mm, for example about 70 mm.
  • the radius of curvature of the membrane 11 is preferably between 80 mm and 120 mm, for example about 100 mm.
  • the pin 12 has a side wall 15 of generally conical shape, surmounted by a substantially plane circular outline top 16 , at the center of which is a pellet 17 of amorphous material not stretched, corresponding to the injection point of the preform from which the container is made.
  • the side wall 15 of the central pin 12 is not smooth but has a broken profile and comprises, substantially at mid-height, a recess 18, the wall 15 thereby presenting, near the apex 16, a narrowed area 19 .
  • the sidewall 15 is concave with its concavity facing away from the main axis X of the container 1.

  • the body 5 substantially retains its original shape given the presence of the stiffeners 6, which, by increasing the radial stiffness of the container 1, limit the ovalization.
  • Bottom 8 essentially crystalline (with the exception of vertex 16 of pion 12), does not undergo, unlike the essentially amorphous bottom of a conventional container, deformation under the effect of the sole temperature of the filling liquid.
  • the bottom 8 initially deforms by deflection of the membrane 11, articulated around its outer edge 13 , accompanied by a lowering of the pin 12. This deflection can eventually lead to a configuration - temporary - where the inner edge 14 of the membrane 11 exceeds the plane of the base 9. This intermediate configuration is shown in dashed line on the figure 3 .
  • the bottom 8 rises, from its intermediate configuration described above, to a final configuration where the membrane 11 bends in the opposite direction around its outer edge 13 , the pin 12 going back to beyond its initial position (that is to say before any filling).
  • the membrane 11 may, in the case of the first embodiment described above, see its inverted curvature with respect to its initial configuration, that is to say that its concavity is turned outwards. of the container 1, as illustrated in dashed line on the figure 3 .
  • annular stiffeners 6 in the form of beads on the body 5 and a deformable membrane 11 in the bottom 8 causes the deformations to be located on the bottom 8, firstly during the hot filling, then during the subsequent cooling of the liquid.
  • the crystallinity of the bottom 8 can be mechanically increased by a so-called boxing process within a mold provided with a sliding mold bottom parallel to the axis.
  • X of the container 1. the mold bottom is first placed in a low position below its final position, which allows, at first, to stretch the bottom 8 of the container 1 beyond its final position. Then the mold bottom is reassembled to give the bottom 8 its final shape by stretching the material to the maximum.
  • a description of such a process can be found in the document FR 2 508 004 .
  • the bottom 8 comprises a substantially plane annular base 9 , bordered in the direction of the axis of the container 1 by a frustoconical step 10 whose apex angle is, as previously indicated, between 30 ° and 90 °.
