FIELD: package and storage.
SUBSTANCE: provided is plastic vessel description, in particular, for liquid products storage under small excess pressure, which has vessel body (2) passing along longitudinal axis, to one longitudinal end of which vessel neck (3) is adjoining, which is equipped with, at least, one drain hole (4). To vessel body (2) other longitudinal end bottom section (5) is adjoining, which has vessel bottom (6) and passing sideways upwards edge zone (8), which enters into vessel body (2). Vessel bottom (6) has concave section (9) curved in vessel inner space direction limited by vessel body (2), which circumference is connected with support surface (7) through axially extending stepped transition zone (10), which enters into passing sideways upwards edge zone (8). Support surface (7) and, at least, stepped transition zone (10) partial zone are interrupted by first number of grooves (11). In concave section (9) second number of panel-shaped projections (12) is formed, which pass, substantially, between stepped transition zone (10) and longitudinal axis and end before stepped transition zone (10).
EFFECT: provided is plastic vessel description, in particular, for liquid products storage under small excess pressure.
