Abstract

Abstract 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 129 words
A blow-molded bottle-shaped container of biaxially oriented synthetic resin integrally molded with a neck at the top of a multi-sided shaped body, comprising: a pair of recesses depressed inwardly on opposing wall portions of the body, each of said recesses being defined by a pair of tapered walls inwardly inclined toward a center of each recess; a grip comprising a first multi-sided shaped body portion between said recesses; a second multi-sided shaped body portion opposite to said grip; and at least one laterally extending reinforcing rib of projecting strip shape crossing both tapered walls of each of said recesses, said at least one laterally extending reinforcing rib having a length substantially equal to a lateral length of said recess and a height less than the depth of said recess.
Claim 2
Dependent Claim 129 words
A blow-molded bottle-shaped container of biaxially oriented synthetic resin integrally molded with a neck at the top of a multi-sided shaped body, comprising: a pair of recesses depressed inwardly on opposing wall portions of the body, each of said recesses being defined by a pair of tapered walls inwardly inclined toward a center of each recess; a grip comprising a first multi-sided shaped body portion between said recesses; a second multi-sided shaped body portion opposite to said grip; and at least one laterally extending reinforcing rib of projecting strip shape crossing both tapered walls of each of said recesses, said at least one laterally extending reinforcing rib having a length substantially equal to a lateral length of said recess and a height less than the depth of said recess.
Claim 3
Dependent Claim 28 words
The blow-molded bottle-shaped container of biaxially oriented synthetic resin according to claim, wherein said reinforcing ribs project concavely in an arch shape bent inward to cross the recesses.
Claim 4
Dependent Claim 35 words
The blow-molded bottle-shaped cotnainer of biaxially oriented synthetic resin according to claim 2, wherein said reinforcing ribs are aligned at such a predetermined interval that a finger of a human head can enter the interval.
Claim 5
Dependent Claim 28 words
The blow-molded bottle-shaped container of biaxially oriented synthetic resin according to claim, wherein a plurality of lateral grooves are aligned across the grip without extending into said recesses.
