FIELD: manufacturing technology.
SUBSTANCE: thermoplastic bottle (1) contains bottom wall (2), made with the possibility of determining supporting plane (SP), neck (6) having hole (6a) of the bottle, shoulder (5) connected to neck (6), and side wall (8), continuing in the longitudinal direction around central axis (Z) of bottle (1) between bottom wall (2) and shoulder (5). Side wall (8) has plane (P1) of symmetry, which includes central axis (Z), first line (PL1) of the side wall and second line (PL2) of side wall (8), defined in plane (P1) of symmetry as a whole below shoulder. Second line (PL2) has second point (11a) at a radial distance ds2 from central axis (Z), which is the minimum distance between side wall (8) and central axis (Z). First line (PL1) has first point (19a) at the radial distance ds1 from central axis (Z), which is the minimum distance between first line (PL1) and central axis (Z). Moreover, ds2<ds1; hs1<hs2, where hs1 is the height of first point (19a), and hs2 is the height of second point (11a), each of which is measured parallel to central axis (Z) from supporting plane (SP). Side wall (8) contains on second line (PL2) at least one thickened section (23), which continues at second point (11a) and above it. Thickened portion (23) has a thickness greater than opposite thickness (E1) provided on first line (PL1) at the same height as the height hs2 of second point (11a).
EFFECT: group of inventions provides the bottle with resistance to loads applied from the upper side when stacking and comfortable grip.
