Embodiment Construction

[0031] figure 1 A container 1 is shown, which is blown or blow-drawn from a preform made of a thermoplastic material such as PET (polyethylene terephthalate). The container 1 , here a bottle, typically has a capacity of 0.5 liters, however, this capacity is non-limiting and may be larger, for example 1.5 liters.

[0032] The container 1 has a main body 2 which extends along a main axis X. The body 2 has a polygonal cross-section (ie perpendicular to the main axis X). The terms "polygon" and "polygonal" are used broadly in this patent application and are not limited to the strict mathematical definition of a closed geometric shape consisting of straight line segments (forming sides of a polygon) joined by their ends (vertices forming a polygon), Instead, it includes approximate geometric shapes whose sides can be curved (such as circular arcs) and whose vertices are circular. According to this definition of a polygon, the cross-section of the container shown in the drawings ...

Abstract

Plastics container (1) comprising a body (2) with a polygonal section which extends along a main axis (X), a shoulder (4) which extends in continuation of the body (2) on an upper side, a neck (5) which extends in continuation of the shoulder (4), and a bottom (3) which extends in continuation of the body (2) on a lower side, the bottom (3) comprising: an annular seat (9) defining a standing perimeter (10), having a polygonal contour formed from a plurality of sides and vertices, and approximately perpendicular to the main axis (X); a central peg (16) having a side wall (17) that has a generally axisymmetric frustoconical shape about the main axis (X) and which is connected to the rest of the bottom (3) by a connecting fillet (19) which has a radius that is variable in revolution about the main axis (X) of the container (1).

Description

technical field [0001] The present invention relates to a container having a bottom having an annular base defining a placement perimeter having a polygonal profile formed by a plurality of sides and vertices, and a centering pin having a generally sectional shape. Conical side walls of revolution about the main axis, the side walls are connected to the rest of the base by connecting fillets. Background technique [0002] Containers with this structure are manufactured according to technical requirements or aesthetic requirements. In this type of container, due to technical requirements, the containers are stackable, the containers are shaped so as to be stackable one on top of the other and for this purpose are provided with a base and a neck which are substantially complementary, so that the lower layer A container can be inserted into the cavity of the base of an upper container of the same kind, the bottom of which is supported on a shoulder of the lower container.
