Definitions
- the invention relates to the field of containers obtained by blow molding or stretch blow molding from a blank (for example a preform or an intermediate container) made of plastic material such as PET (polyethylene terephthalate).
- a blank for example a preform or an intermediate container
- plastic material such as PET (polyethylene terephthalate).
- the invention relates more particularly to flat containers, that is to say to the containers having in section a flattened shape, typically oval or rectangular.
- This type of container is particularly suitable for certain applications (especially cosmetics) in which the content has a high viscosity, a pressure on the container body promoting the flow of the contents.
- the stability of the container is inversely proportional to its ease of handling. It is a compromise between these two constraints aimed at by the solution disclosed in the aforementioned document WO 2007/127789, which proposes on the one hand to maintain the ratio W / D (where W is the large width of the container, and D is small). width) between 1.2 and 1.8, and secondly to provide the bottom of the container rounded chamfers (sic) whose diameter is smaller in the small width of the container that in its wide.
- a first simple solution could be to increase the blowing pressure, but manufacturers face the need to control the energy consumption of machines, forcing the blowing pressure down.
- a second simple solution could be to increase the blowing time (and thus the cycle time) to promote a better impression of the bottom, but this solution also comes up against the process constraints, which aim at reducing the cycle time for increase production rates.
- the invention aims to provide a flat container capable of filling one or more (and preferably all) of the following objectives: - good stability;
- a plastic container provided with a flattened body and a bottom in the extension of the body at a lower end thereof, the bottom comprising:
- a peripheral seat defining an annular laying plane whose outline has, along a major axis, a large dimension A and, along a minor axis perpendicular to the major axis, a small dimension A 'strictly smaller than the large dimension, this seat having:
- ⁇ a concave arch that extends from the seat to a central area.
- this container has both a good rigidity at its seat (to the benefit of the stability of the container), especially in the plane of the minor axis, while providing a good breathability seat.
- the seat has, between the laying plane and the vault, an inner annular cheek substantially perpendicular to the laying plane, this cheek extending, along the major axis, on a height D such that:
- the height D of the cheek is such that:
- the height D of the cheek is such that:
- the cheek extends along the minor axis to a height D such that:
- the width C of the seat along the major axis is such that:
- the width C of the seat along the minor axis is such that:
- Figure 1 is a perspective view from below of a plastic container, inset, on an enlarged scale, the bottom of the container;
- Figure 2 is a bottom view of the bottom of the container of Figure 1;
- Figure 3 is a detailed sectional view of the container of Figure 2, according to the sectional plane III-III, according to a first embodiment
- Figure 4 is a detailed sectional view of the container of Figure 2, according to the sectional plane IV-IV, according to the first embodiment;
- Figure 5 is a view similar to Figure 3, according to a second embodiment
- Figure 6 is a view similar to Figure 4, according to the second embodiment.
- Figure 1 a container 1 formed by stretching, in a mold in the cavity of the container 1, a plastic preform such as PET (polyethylene terephthalate).
- PET polyethylene terephthalate
- the container 1 comprises a body 2 which extends along a main axis X and extends, on a lower side, by a bottom 3, and, on an upper side, opposite the bottom 3, by a shoulder 4 itself. even extended by a neck 5 defining a drinking.
- the container 1 At the junction between the body 2, at the lower end thereof, and the bottom 3, the container 1 has an external connection fillet 6 having a low radius radius arc profile (less than or equal to 2 mm). ).
- the bottom 3 comprises a peripheral seat 7 which defines a plane 8 of continuous laying, substantially perpendicular to the main axis X of the container 1, and by which the latter can lie flat on a flat surface (in particular the upper surface of a table or conveyor belt, within a handling machine on a container production line).
- the laying plane 8 is bounded transversely outwards (that is to say opposite to the axis X of the container) by an external perimeter 9 defined internally by the fillet 6.
- the container 1 has, in cross section (that is to say, perpendicular to its axis X), a flattened shape, in this case substantially oval. This shape extends to the bottom 3, especially at the level of the laying plane 8, whose contour is substantially the same as the body 2 in section and which, like an ellipse, has: along a major axis (In the sectional plane III-III in Figure 2, or in the plane of the sheet in Figure 3), a large transverse extension A (called large dimension), measured perpendicular to the axis X at the perimeter 9, and
- the seat 7 comprises an inner annular cheek 10 that extends axially inwardly of the container 1 in the extension of the laying plane 8, substantially perpendicular to it.
- the seat 7 comprises an internal fillet 11 having a low radius circular arc profile (less than or equal to about 2 mm), which connects the laying plane 8. on the cheek 10.
- the seat 7 comprises, instead of a fillet of connection of the laying plane 8 to the cheek 10, a step 11 'forming a recess at the junction between the Laying plane 8 and the cheek 10.
- this joint plane being defined between a wall of the mold (at the footprint of the body and the laying plane) and a mold bottom (at the footprint of the vault).
- the laying plane 8 is delimited transversely inwards (that is to say in the direction of the axis X of the container) by an internal perimeter 12, defined externally by the internal discharge 11 (in the case of the first embodiment). of realization) or, respectively, by an inner edge of the step 11 ', at its junction with the cheek 10 (in the case of the second embodiment).
- the bottom 3 further comprises a concave arch 13, concavity facing outwardly of the container 1.
- This arch 13 extends from the seat 7, in the extension of the cheek 10, to a central zone 14 of the bottom defining a pin which extends axially projecting towards the interior of the container 1.
- C a width of the laying plane 8 (coincides with a width of the seat 7), measured radially along the major axis between the inner perimeter 12 and the outer perimeter 9, respectively between an inner edge of the step 11 ', at its junction with the cheek 10, and the outer perimeter 9;
- D height of the cheek 10 (coincides with an internal height of the seat 7), measured along the major axis (that is to say in the section plane III in Figure 3, or in the plane of the sheet in Figure 3 or Figure 5) between the laying plane 8 and the junction of the cheek 10 with the roof 13;
- the bottom 3 is designed to maximize the stability of the seat 7 while promoting its blowing.
- the seat 7 is dimensioned so that its width C is variable as a function of its transverse extension. More specifically, the width C of the seat 7 is dimensioned as follows:
- the width C of the seat 7 along the major axis is such that:
- the width C of the seat 7 along the minor axis is such that:
- the width C of the seat 7 along the major axis is preferably strictly greater than its width C along the minor axis:
- the cheek 10 is also sized according to the transverse dimension of the seat 7:
- the height D of the seat measured along the major axis is such that:
- the height D of the seat measured along the major axis is such that:
- This dimensioning makes it possible to maintain a good stability of the container 1 in particular in the plane of the minor axis (that is to say of the small dimension), while maintaining a good puffability of the container in the plane of the major axis, where the stretching is more difficult but where the stability of the container 1 is naturally better.
- the greatest width of the laying plane 8 along the major axis contributes to a good breathability of the seat 7 in this direction, minimizing the risk of appearance of distortions (or flatness defects) on the laying plane.
- the narrowness of the laying seat 7 along the minor axis gives it a quasi-linear character, which reduces the risk of hyperstatism of the seat 7 and therefore increases the stability of the container 1.
- the dimensioning of the cheek 10 contributes in particular:
- the boxing technique in which the container 1 is blown into a mold provided with a side wall defining a cavity in the cavity of the body 2 and a mounted mold bottom movable relative to the wall between a low position in which the bottom is spaced from the cavity, and a high position in which the bottom closes the cavity by completing the cavity of the container 1.
- the mold bottom initially in the low position, is reassembled during blowing, which leads to an overstretching of the material at the bottom 3, favorable to its impression, especially at the seat 7.
