Synthetic resin bottle-shaped container having bottom support

摘要

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).
