Abstract

DEVICE TO PRACTICE HOLLOW HOLES FLAT IN A CONTAINER OBTAINED IN DEEP STUFFING MOLD, AND CONTAINER MADE WITH SUCH DEVICE, characterized in that the deep drawing mold (38) has at least one protruding stem, pivot (12, 23, 41) or analogous on whose free end (14, 25) rests in a flexible arrangement against the force of a spring (20, 30, 49), a male (18, 28, 44) foldable about a transverse axis (17, 27, 43) with a lateral or protruding insert (19, 29, 45), said male being covered, for the purposes of forming the undercut projection, together with the stem, pivot or the like, during the deep drawing process, by the sheet made of previously heated plastic, so that the male, when removing the already formed container, collapses around its axis on a position in which its insert or lateral projection releases the undercut portion of the projection of the container.
