吹制或拉吹热塑材料制成的中空主体底部及该中空主体
摘要：
通过吹制或拉吹热塑材料制成的预型件所获得的中空主体的底部，所述底部包括一横向支撑表面，并且在所述横向支撑表面的两侧包括：一横向外边缘(7)和一具有横向中心部分(11)的凹形的内壁，所述横向中心部分包含具有低结晶度的材料制成的料头体(12)；所述底部包括加强肋(1)，所述加强肋具有一外部边缘(13)，所述外部边缘靠近横向外边缘(7)但未到达所述横向外边缘(7)，这些加强肋(1)具有一内部边缘(14)，所述内部边缘靠近横向中心部分(11)但未到达所述横向中心部分(11)，所述横向支撑表面由加强肋(1)所间断的区段(6a，6b，6c，6d，6e)形成；所述中空主体的底部(4)还包括凹槽(2)，所述凹槽的远端部分(24)接近但未到达底部的外边缘(7)，凹槽(2)的近端部分(25)相切于横向支撑表面但未通到所述横向支撑表面。
摘要（英）：

Bottom of hollow ware obtained by the blow moulding or stretch-blow moulding of a thermoplastic preform, this bottom having a transverse bearing surface and, on either side of this transverse bearing Bottom of hollow ware obtained by the blow moulding or stretch-blow moulding of a thermoplastic preform, this bottom having a transverse bearing surface and, on either side of this transverse bearingsurface, a transverse external edge (7) and a concave internal wall with a transverse central portion (11) containing a disc (12) of material having a low crystallinity, this bottom including reinforcsurface, a transverse external edge (7) and a concave internal wall with a transverse central portion (11) containing a disc (12) of material having a low crystallinity, this bottom including reinforcing ribs (1) having an outer edge (13) coming close to the transverse external edge (7) but without reaching this transverse external edge (7), these reinforcing ribs (1) having an inner edge (14) coming ribs (1) having an outer edge (13) coming close to the transverse external edge (7) but without reaching this transverse external edge (7), these reinforcing ribs (1) having an inner edge (14) coming close to the transverse central portion (11), but without reaching this transverse central portion (11), the transverse bearing surface being formed from segments (6a, 6b, 6c, 6d, 6e) interrupteding close to the transverse central portion (11), but without reaching this transverse central portion (11), the transverse bearing surface being formed from segments (6a, 6b, 6c, 6d, 6e) interruptedby the reinforcing ribs (1), this hollow ware bottom (4) further including notches (2), the distal end portion (24) of which comes close to but does not reach the external edge (7) of the bottom, theby the reinforcing ribs (1), this hollow ware bottom (4) further including notches (2), the distal end portion (24) of which comes close to but does not reach the external edge (7) of the bottom, theproximal end portion (25) of the notches (2) being tangential with the transverse bearing surface but not opening into this transverse bearing surface.proximal end portion (25) of the notches (2) being tangential with the transverse bearing surface but not opening into this transverse bearing surface.
