Definitions
- the present invention relates to improvements made to containers made of thermoplastic material and provided with a bottom of the type known as "Champagne bottom” (that is to say a bottom which is strongly curved towards the interior of the container), said bottom comprising a central button projecting downwards (that is to say in the concave face of the bottom), a peripheral support zone by which the container can rest stably on a substantially flat support, and ribs radiating from from said central button to said peripheral support zone.
- the so-called “Champagne bottoms” offer the advantage of allowing the creation of a peripheral, flat and above all continuous support zone over its entire extent, so that they provide a remarkably stable seat for the containers placed on a substantially flat support.
- Bottoms of this type are particularly advantageous when the containers are filled with liquids under pressure (carbonated drinks for example) because these bottoms, by their shape with strong convexity turned towards the inside, are intrinsically resistant to the pressure which is applied to them from the inside and they are therefore stable.
- obtaining these advantageous characteristics requires a sufficient thickness of thermoplastic material, which thickness is notably greater than that of the wall of the body of the containers (see for example the document FR 2 730 471) and makes the manufacture of the containers more delicate. by blow molding or stretch blow molding from heated preforms.
- Numerous variants of the production of Champagne bottoms are known which tend to obtain improved characteristics of flatness and stability of said bottoms, often in conjunction with the search for a minimum thickness of the material and therefore a lower cost price of these containers.
- the object of the invention is to propose an original Champagne base structure which combines all the advantageous characteristics specific to this type of base, at the same time as it saves on the quantity of material necessary for the production of the containers and therefore let it reduce the cost.
- the invention provides a container made of a thermoplastic material and provided with a bottom of the "Champagne bottom" type comprising a central button projecting downwards, a peripheral support zone and an intermediate vault provided with ribs. radiating from the central button to the support zone, which container, being arranged in accordance with the invention, is characterized in that
- the ribs are dihedral in shape with a V-shaped cross section with a median plane substantially parallel to the axis of the container and follow one another without discontinuity, and
- the ribs have a longitudinal profile which is curvilinear, the bottoms of the ribs, in their zone which borders the central button, rising higher than the base of said central button and the bottoms and edges of the ribs, in their zones which border the zone d '' support, having curvatures gradually merging into a continuous rounding without breaking curvature immediately above the support area so that it is substantially flat and continuous over its entire extent.
- the Champagne bottom vault which extends between the central button and the peripheral support zone has increased mechanical strength not only by the presence of ribs, but also by the very shape of the ribs which, being arranged one after the other without discontinuity, bear against each other and reinforce each other.
- This mechanical resistance is also increased by the specific longitudinal profile of each rib, with the bottom of each rib which, from the central button, rises higher than the latter towards the interior of the container and which consequently has a curvature. very pronounced with convexity facing
- the container providing it with increased resistance to pressure. All of these individual characteristics are generally combined in obtaining a Champagne background which is more resistant than the bottoms currently known and which is therefore capable either, with a wall thickness identical to that of the known bottoms, of withstanding increased pressures without deformation, or advantageously to be able to be produced with a smaller thickness to be able to withstand a given pressure. It should be noted here that the possible reduction in thickness relates not only to the vault equipped with said dihedral ribs, but also and above all to the peripheral support zone, the thickness of which is traditionally the greatest.
- the central button is in the form of a circular plate projecting downwards.
- the container is a bottle of generally approximately cylindrical shape of revolution and the support area is annular and substantially coaxial with the central button, the dihedral ribs extending radially.
- this container has ribs each having the same angular extent.
- the bottom of the bottle has ten ribs each having an identical angular extent. More generally, it can be envisaged that the number of ribs varies substantially with the diameter of the support zone, in particular between 8 and 16 for bottles of standard diameters. The arrangements in accordance with the invention can lead to substantial savings in material.
- FIGS. 1 and 2 are illustrated, 'by way of example, the lower part of a bottle 1 of generally approximately cylindrical shape of revolution, the side wall 2 of which is connected internally to a base 3 of the "Champagne base” type , that is to say strongly domed inward.
- the bottle 1 is made of thermoplastic material, in particular PET, and manufactured by a blowing or stretch-blowing process of a preform.
- the bottom 3 comprises: a central button 4 (constituted by or including the pellet of crystallized material resulting from the process of injecting the preform), which is advantageously produced in the form of a circular plate projecting downwards; a peripheral support zone 5, here of annular shape, which extends substantially in a plane so that the container can rest stably on a flat support; and an intermediate zone or arch 6 equipped with ribs 7 radiating from the central button 4 to the support zone 5.
- the ribs 7 extend from the central button 4 to the zone support 5, but excluding it; in other words, the ribs do not cut the support zone 5 which thus extends continuously annularly.
- the ribs 7 are dihedral, that is to say formed by two flat walls 7a, 7b inclined relative to each other with a V-shaped cross section symmetrical with respect to the median plane 7c substantially parallel to the axis la of the bottle and passing through said axis.
- the ribs 7 follow one another without discontinuity, so that all the ribs distributed circularly bear against each other and reinforce each other, which leads to a vault 6 having better mechanical strength and better resistance to the pressure applied to it.
- the ribs 7 have a curvilinear longitudinal profile.
- the bottoms 7d of the ribs in their area bordering the central button 4, rise higher than the base of said button 4, so that the bottoms 7d have, in this area, a very pronounced curvature, while, in the same area, the 7th edges of the ribs deviate from the central button substantially perpendicular to the axis la.
- This arrangement contributes to strengthening the resistance of the arch 6.
- the bottoms 7d and edges 7e of the ribs 7 have respective longitudinal profiles such that, towards the periphery of the bottom, they have curvatures gradually merging into a continuous rounding and without rupture of curvature immediately above (at 8) the area support 5, so that it is flat and continuous over its entire extent.
