A can contains a neck with a thread and a body with the upper, medium and lower parts, from which the upper one is made with relief surface asperities, and the cylindrical medium part is made with a smaller diameter, than upper and lower ones, the parts are joined with the neck and a bottom. Thus the upper part of body is made in the form of sequentially joined first radial segment located from the side of medium part, a conic segment which is narrowed upward, and the second radial segment located from the side of neck. The lower part is made in the form of a cylindrical segment located from the side of medium part, a conic segment narrowed downward and smoothly conjugated with the bottom. Thus, the ratio of the maximum body diameter to overall can height is equal to 0.7±0.15 and the ratio of height of the medium part of body to the overall can height is equal to 0.35±0.025. Protrusions are distributed on a circle with intervals, and a surface enclosing the protrusions is made with corrugation. The strength for transportation and filling with product under pressure is provided, the product quality is maintained. |
