Synthetic resin bottle with handle and its production method

A blow-molded bottle-shaped container of biaxially oriented synthetic resin integrally molded with a neck at the top of a cylindrical body thereof, comprising a pair of recesses depressed inwardly on the cylindrical wall thereof at both sides of the cylindrical body and spaced so that one remaining container body surface of the container body forms a grip by the formation of said recesses. The blow-molded bottle-shaped container of biaxially oriented synthetic resin can enhance sufficiently the mechanical strength of the recesses formed on the container body by providing reinforcing ribs for effectively dispersing internal pressure acting one the recesses.

Biaxial-orientation blow-molded bottle-shaped container with axial ribs

A blow-molded bottle-shaped container of biaxially oriented synthetic resin integrally molded with a neck at the top of a cylindrical body thereof, comprising a pair of recesses depressed inwardly on the cylindrical wall thereof at both sides of the cylindrical body and spaced so that one remaining container body surface of the container body forms a grip by the formation of said recesses. The blow-molded bottle-shaped container of biaxially oriented synthetic resin can enhance sufficiently the mechanical strength of the recesses formed on the container body by providing reinforcing ribs for effectively dispersing internal pressure acting on the recesses.

Bottle-shaped container having inclined grip surfaces

A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin includes a pair of recesses depressed inwardly on the right and left side parts of a rear half portion substantially at the central height position of a cylindrical container body to form a grip to be grasped by one hand. The bottle-shaped container can enhance the buckling stiffness of an integrally molded grip by providing parallel grooves and/or reinforcing ribs in and around the grip.
