    • The invention relates to a bottom of a mould (13) for a mould for producing containers, especially bottles, by blow moulding or blow drawing, said containers having a body and a bottom (14) of a container, comprising a peripheral base (15) in the shape of a crown, which is connected on the inside to a central area (16) forming an arch consisting of a plurality of radiating impressions (17) alternating with a plurality of radiating projections which are distributed in an angular and equidistant manner about a central axis (Y) of the bottom (14) of the container. For the moulding of the central area (16) of the bottom (14) of the container, the bottom (13) of the mould comprises: a plurality of radiating projecting branches (19) distributed in an angular and equidistant manner, and extending approximatively radially to the axis (X) of the bottom of the mould; a central core (20) comprising a lateral wall (21) to which the branches (19) are connected; and in-between sections (22) forming cores of angular sectors regularly separating said branches from each other. The bottom (13) of the mould is characterised in that each radiating projecting branch (19) has an upper part (23) in the form of an inclined platform which descends from the centre towards the periphery with at least two points (24, 25) of inflection of the curve.

    • A wide-mouth, hot-fill plastic container (10) having pinch-grips (14) and a high push-up base (24) and method for forming the same. According to the method, a preform (40) is positioned in a mold cavity (34) defined in part by surfaces which deviate substantially inward to form pinch-grips (14) in the resulting container (10). Initially, a mold base (50) is located so that it defines an initial mold cavity (34) whose length is greater than the final length of the container (10). The preform (40) is axially stretched in the cavity to a length greater than the container's final length. After stretching the preform (10), the preform is generally expanded radially outward under low pressure. The mold bottom (50) is then moved to a position where the length of the cavity (34) is about the same as the final length of the container (10). The preform (40) is further expanded under high pressure such that it contacts the molding halves (36) thereby forming the finished container (10). As a result of the above method, the base and contact ring of the container (10) is fully circumferentially formed below the pinch-grips (14). The container (10) is also heat treated to allow for filling with a hot product.
    • 一种具有夹紧手柄(14)和高上推基座(24)的广口热填充塑料容器(10)及其形成方法。 根据该方法,预成型件(40)定位在模具腔(34)中,模腔(34)部分地由基本上向内偏离的表面限定,以在所得容器(10)中形成夹紧夹(14)。 最初,模座(50)定位成使得其限定长度大于容器(10)的最终长度的初始模腔(34)。 预成型件(40)在空腔中轴向拉伸至大于容器最终长度的长度。 在拉伸预成型件(10)之后,预制件通常在低压下径向向外膨胀。 然后将模具底部(50)移动到空腔(34)的长度与容器(10)的最终长度大致相同的位置。 预成型件(40)在高压下进一步膨胀,使其与半成品(36)接触,从而形成成品容器(10)。 作为上述方法的结果,容器(10)的基部和接触环在夹紧柄(14)的下方完全周向地形成。 容器(10)也被热处理以允许填充热产品。
