The container which is produced with the thermoplastics which possess the petal forma bottom

摘要

A thermoplastic container, such as a bottle, obtained by extrusion-blow or injection-blow molding and having a petaloid base ( 6, 7 ). The base includes a convex wall ( 7 ) hemispherical in shape; the wall ( 7 ) is linked to the wall ( 2 ) forming the container body by a marginal zone ( 8 ) with a curve (R 1 , R 2 ). Members ( 6 ) originate from the hemispherical wall ( 7 ) and are separated in pairs by a part thereof; the top end of each member is directly linked to the wall ( 2 ) forming the body.
