Abstract: The invention concerns an injecting/blowing device comprising at least one mold for injecting a thin-walled hollow preform capable of being transformed into a more voluminous hollow body by blowing, said mold including a counter mold defining the inner surface of the cavity, a cure located in the cavity and spaced apart from said inner surface, a preform impression located between the counter mold inner surface and the core, and which will receive the melt, at least two main preferential flow channels (CEPP) optionally at least two secondary preferential flow channels (CEP), each CEP being delimited by at least one recessed zone at the surface of the core and the inner surface of the cavity.

Abstract: A bottle made of plastic material having a body extending along a central axis which comprises: a lower portion having a cross section with an essentially constant profile, followed by a gripping portion, and ending in an upper portion having a section with an essentially constant profile arranged in alignment with the profile of the section of the lower portion. The gripping portion comprises two globally plane gripping panels arranged parallel to one another and in relation to the central axis at a distance which is adapted for a hand taking. These panels have at least one reinforcing relief which extends in a transverse plane and are interconnected by connecting panels extending in continuation of the lower and upper portions by means of rounded corners located at the circumferential ends of the panels.

Abstract: A molded plastics bottle including a bottom having improved strength and stability, the bottom comprising a concave central portion (26) which connects via a plane annular surface (28) with a convex peripheral surface (30) for standing on a support surface (32), radial grooves (38) being formed in said convex annular surface (30) and connecting tangentially with the plane annular surface (28).

Abstract: The invention discloses a strain gauge weighing device in which the load cell comprises a not very flattened flexion bar associated with a flat and wide parallel secondary plate connecting a mobile upright to a fixed upright. A platform is fast with the mobile upright whereas a base is fast with the fixed upright. Strain gauges are spaced apart on the surface of the flexion bar and connected in a Wheatstone bridge for measuring the load.
