Abstract
Abstract This invention relates to a synthetic resin bottle-shaped container comprising a bottle-shaped main body and a pedestal body for providing stable self-standing capability to the main body. The bottle-shaped main body (1) is made of a biaxially oriented blow-molded synthetic resin material. A center portion (6) of a bottom portion (3) of the main body (1) is depressed inwardly and a curved outer peripheral surface area of the bottom portion (3) is formed with a wide press-fit recess (4) to be engaged with a pedestal body (7). The pedestal body (7) is a short cylindrical portion with an outer diameter substantially equal to that of the bottle portion (2) of the main body (1) and comprises an upper half portion (9) for engaging with the press-fit recess (4) of the bottom portion (3) and a lower half portion (8) for accommodating the bottom portion (3) so that the lowest end of the pedestal body (7) is positioned below the lowest end of the bottom portion (3 ). The pedestal body (7) is easily and exactly engaged with the main body (1) and also provides a high protection capability against external impact to the bottom portion (3) of the main body (1).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A synthetic resin bottle-shaped container comprising: a biaxially-oriented blow-molded bottle-shaped body having a body portion with a diameter and a curved bottom portion, said curved bottom portion having an inwardly concave bottom and an outer peripheral outwardly convex surface extending between the concave bottom and body portion forming an outwardly convex press-fit recess, said convex press-fit recess extending circumferentially around said bottom portion and longitudinally from said body portion to an annular groove located between the concave bottom and the convex press-fit recess of said bottom portion, wherein a high-projecting portion extends circumferentially around said concave bottom below said annular groove radially outwardly from said convex press-fit recess; and a pedestal body for supporting said bottle-shaped body having an exterior surface and an inner surface, said inner surface including an upper concave portion and a lower pedestal portion with a press-fir rib therebetween, said upper concave portion being shaped to abut and substantially entirely cover said convex press-fit recess, said press-fit rib engaging said annular groove and being retained therein by said high projecting portion, said lower pedestal portion extending around and below said bottom portion.
