Definitions

  • the object of the invention is to remedy, inter alia, the difficulties of completely rinsing the external surfaces of plastic containers described above, to arrange the latter so that the caustic detergents and rinsing liquids can flow over all these external surfaces without being able to stagnate there, in order to eliminate all traces of detergent.
  • a projection of the base on a plane passing through the laying surface is included in a projection of the hollow body on the same plane or substantially coincides with this latter projection.
  • the invention also relates to a use of the container according to the invention.
  • this use consists, in an industrial and commercial circuit, of filling the container with a drink, in particular natural mineral water, for storing and distributing it for consumption, and, when the container is empty, to collect, wash and reuse it, for the same storage and distribution purposes, in an industrial and commercial beverage circuit, possibly the same circuit.
  • a drink in particular natural mineral water
  • Figure 1 shows an elevational view, with partial breaking of the base, of an embodiment of a container according to the invention.
  • Figure 2 shows in elevation, on another scale, with partial breakage and section, another embodiment of a container according to the invention.
  • Figure 3 shows in elevation, with broken, on the same scale as that of Figure 1, a view of a bottom area of a container according to the invention.
  • FIG. 4 shows an axial section on an enlarged scale, in elevation, with breakage, of the base of the container of FIG. 1.
  • the bottle 1 according to the invention can have any usual cross section in the field of the product to be stored and transported.
  • This cross section could for example be hexagonal.
  • a circular cross section is however generally preferred both for the hollow body 2 and for the base 7, the hollow body 2 advantageously being cylindrical over a substantial section 11 of axial length h1 (FIG. 1).
  • a projection of the base 7 on a plane passing through the laying surface 8 is included in a projection of the hollow body 2 on the same plane or substantially coincides with this latter projection.
  • the external diameter d2 of the cylindrical hollow body 2 is greater than or at most equal to the external diameter d1 of the base 7.
  • the hollow body 2 comprises the cylindrical section 11 of axis 12, this is perpendicular to the laying surface 8. It is then advantageous (FIG. 3) that the bottom zone 7 connected to this cylindrical section 11 has an end portion 13 partially in shape of a spherical cap, of radius R (in axial section, for the internal surface), which is coaxial with the cylindrical section 11 and whose concavity is turned towards the latter, the cap possibly being flattened at its bottom 14, close to its intersection with said axis 12.
  • the end portion 13 of practically hemispherical shape advantageously makes it possible to obtain a substantially constant thickness of the wall of the hollow body 2 at this location.
  • This consistency of thickness ensures the most regular and homogeneous cooling and, consequently, an almost total absence of internal tensions in this wall.
  • Such internal tensions when they exist, give rise in the presence of aggressive products (washing solutions, lubricants for transport chains, etc.), during washing at high temperature, to phenomena of "stress cracking" by which appear in the wall of tension cracks which force to discard bottle 1 after washing (unnecessary handling and washing costs and loss of bottle 1).
  • the portion 13 in a spherical cap may comprise, opposite its flattened bottom 14, a region with radius r (in axial section, for the internal surface) substantially smaller than the radius R above, of so that said end portion 13 ends in a cross section III-III greater than the other cross sections of this same end portion 13 but preferably less than the cross section of diameter d2 of the cylindrical section 11.
  • a base 7 of diameter d1 less than or equal to the diameter d2 can surround at least the end portion 13 while maintaining the above-mentioned interval 10 between the rest of the base 7 and hollow body 2.
  • the bottom zone 4 also has an intermediate zone 15 whose cross section decreases progressively towards the end portion 13 and / or in steps (FIGS. 3 and 1), from the cross section of external diameter d2 of the cylindrical section 11 to the cross section III-III of said end portion 13.
  • the base 7 of the invention preferably has in its general appearance the form of a hollow element of revolution 16 which, in the state fixed to the hollow body 2, is coaxial with the cylindrical section 11 and surrounds the end portion 13 above and advantageously also the intermediate zone 15 while leaving the above-mentioned interval 10 open.
  • This arrangement gives the entire bottle a pleasant aspect of continuity between the hollow body 2 and the base 7 when the diameters d1 and d2 are very close.
  • the laying surface 8 of the base 7 is advantageously located beyond the intersection between the portion 13 in the form of a cap and the axis 12, opposite the cylindrical section 11. In this way, the bottom of the hollow body 2 is protected as much as possible against friction, and therefore scratches, on automatic transport elements, storage surfaces, etc.
  • the base 7 advantageously has for example (FIGS. 4 and 1) three regularly distributed supports 17, arranged to locate the hollow body 2 relative to the base 7, at least during an operation for fixing the hollow body. 2 at the base 7, so as to form the gap 10.
  • These supports 17 may have a stud shape if, for example, after the fixing operation they are no longer in contact with the hollow body 2, as is explained below.
  • the base 7 in the form of an element of revolution 16 essentially comprises a wall 18 of a type of sleeve, erected substantially parallel to the direction of the axis 12 and provided with stiffening ribs 19 and / or 20 regularly distributed, for example respectively on the external 21 and internal 22 faces of the wall 18, and each extending parallel to the axis 12 on at least part of the face 21 , 22 corresponding.
  • an annular collar 23, fixed in the base 7 to the abovementioned internal face 22 and extending parallel to the laying surface 8, is provided between the latter and the hollow body 2 in the fixed state, in order to stiffen the 'base 7 against a radial crushing.
  • An abovementioned interval 10 is also provided between this annular collar 23 of stiffening and hollow body 2.
  • the base 7 advantageously comprises, on the side of its laying surface 8, at least one passage orifice 24 for the above-mentioned fluid, preferably of a large section relative to the laying surface 8 in order to facilitate washing, rinsing and drying of the bottle 1 between base 7 and hollow body 2.
  • the fixing locations 9 between hollow body 2 and base 7 are constituted by spots of adhesive resistant to washing solutions of the container and to thermal stresses, for example a CECA adhesive from Elf Aquitaine, of the XPU18007 type, which has a hardened state in the hardened state relative to its state of application to the elements to be bonded 2, 9.
  • a CECA adhesive from Elf Aquitaine
  • hot melt a hot melt adhesive
  • the glue dots that is to say the fixing locations 9, to be arranged at or near the abovementioned supports 17.
  • the hollow body 2 is made of bioriented synthetic material, possibly at more than 30% of crystallinity, advantageously at approximately 40% of crystallinity, preferably released from internal tensions, in particular in the bottom zone 4.
  • This material synthetic is for example polyethylene terephthalate.
  • This high crystallinity is obtained by known methods of blowing the hollow body 2 in a mold, to a dimension greater than its final dimension, by a heat treatment contracting the hollow body of greater dimension to a dimension less than its final dimension, and finally by a new blowing in a mold to give the hollow body 2 said final dimension.
  • This high crystallinity provides, among other things, a better impermeability of the wall of the latter to washing and rinsing products as well as to the drinks which are stored there. This practically results in an absence of subsequent restitution by said wall of flavors which it would have accumulated and which could modify the flavor of a drink which is stored there later or which could give a flavor by example to a mineral water stored in the bottle 1 after a recycling wash thereof.
  • the high crystallinity chosen also gives three-dimensional stability to the bottle 1 when it is subjected to thermal stresses.
  • the container 1 according to the invention is used in a recyclable manner, with reuse as it is, in an industrial and commercial circuit of drinks sold in bottles according to the invention, in particular natural mineral water whether it is carbonated, slightly carbonated or non-carbonated, to store and distribute these drinks for consumption.
  • the container 1 is empty, it is collected, washed, rinsed and reused for the same purposes, either for the same drink as that which was stored there in the previous round or for another drink compatible with the material of the hollow body 2.
  • the container 1 according to FIG. 2 allows a buyer to easily check in the bottom of the container, for example, the good condition of purity of a drink which is stored there.
  • the same possibility can exist if provision is made in the base 7 (of FIGS. 1 and 4) for lateral holes suitably arranged so as to be able to see through them the bottom of the container and especially of the product stored therein, product which can be, among other things, a liquid other than a drink.
  • the base 7 of FIG. 2 can for example be provided with three pillars extending upwards from its upper face, to be fixed to the hollow body and for keep it away from the base 7 proper and to allow viewing of the bottom of the hollow body 2: the product it contains, the state of cleanliness of this bottom ...
