Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin comprising: a container body defining a longitudinal center line and having a shoulder and neck portion at an upper end thereof and a bottom portion at a lower end thereof; a pair of recesses depressed inwardly on opposite sides of a rear half portion of the container body substantially at a central height position of the container body to form a grip to be grasped by one hand, said recesses including tapered parts disposed oppositely with respect to the longitudinal center line and having inclined surfaces substantially inclined in a direction from the rear half portion of said container body towards a center thereof, said recesses having a nadir area aligned with an area including a point defining the center of gravity of said container; and a substantially X-shaped projection formed from a pair of reinforcing ribs projecting from the surface of said tapered part of each of said recesses, said X-shaped projection extending substantially over an entire height and width of said tapered part.
Claim 2
Dependent Claim
175 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin comprising: a container body defining a longitudinal center line and having a shoulder and neck portion at an upper end thereof and a bottom portion at a lower end thereof; a pair of recesses depressed inwardly on opposite sides of a rear half portion of the container body substantially at a central height position of the container body to form a grip to be grasped by one hand, said recesses including tapered parts disposed oppositely with respect to the longitudinal center line and having inclined surfaces substantially inclined in a direction from the rear half portion of said container body towards a center thereof, said recesses having a nadir area aligned with an area including a point defining the center of gravity of said container; and a substantially X-shaped projection formed from a pair of reinforcing ribs projecting from the surface of said tapered part of each of said recesses, said X-shaped projection extending substantially over an entire height and width of said tapered part.
Claim 3
Dependent Claim
41 words
The blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin according to claim 1, wherein rib strips project along said pair of reinforcing ribs at upper and lower parts of the substantially X-shaped projection and at the rear of the grip.
Claim 4
Dependent Claim
62 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin as claimed in claim 1 further comprising: a pair of parallel upper and lower reinforcing grooves extending around an exterior peripheral surface of said container, said upper groove being located between said shoulder and neck portion and said recesses, and said lower groove being located between said bottom portion and said recesses.
Claim 5
Dependent Claim
38 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin as claimed in claim 3, further comprising: a notch formed in the bottom portion at a rear half portion of the container body and extending between the recesses.
Claim 6
Dependent Claim
26 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin as claimed in claim 1, further comprising: a substantially rectangular cross-section above and below said recesses.
Claim 7
Dependent Claim
41 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin as claimed in claim 5, wherein said shoulder and neck portion at the upper end thereof has a smaller cross section than said container body immediately above and below said recesses.
Claim 8
Dependent Claim
71 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin as claimed in claim 5, further comprising: a secondary recess portion in said body, said secondary recess portion extending across a front face of said substantially rectangular cross sectional body from a first side containing one of said recesses to a second side containing a second of said recesses, said secondary recess portion having a greater longitudinal dimension than said recesses.
Claim 9
Dependent Claim
199 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin, comprising: a container body defining a longitudinal center line and having a shoulder and neck portion at an upper end thereof and a bottom portion at a lower end thereof; a pair of recesses depressed inwardly on opposite sides of a rear half portion of the container body substantially at a central height position of the container body to form a grip to be grasped by one hand, said recesses including tapered parts disposed oppositely with respect to the longitudinal center line and having inclined surfaces substantially inclined in a direction from the rear half portion of said container body towards a center thereof, said recesses having a nadir area aligned with an area including a point defining the center of gravity of said container; a substantially X-shaped projection formed from a pair of reinforcing ribs projecting from the surfaces of said recesses; and a pair of parallel upper and lower reinforcing rib grooves located entirely in the grip between upper and lower limits of the recesses and extending between the tapered part of one recess and the tapered part of the opposite recess without extending into the recesses.
Claim 10
Dependent Claim
199 words
A blow-molded bottle-shaped container of biaxially oriented thermoplastic synthetic resin, comprising: a container body defining a longitudinal center line and having a shoulder and neck portion at an upper end thereof and a bottom portion at a lower end thereof; a pair of recesses depressed inwardly on opposite sides of a rear half portion of the container body substantially at a central height position of the container body to form a grip to be grasped by one hand, said recesses including tapered parts disposed oppositely with respect to the longitudinal center line and having inclined surfaces substantially inclined in a direction from the rear half portion of said container body towards a center thereof, said recesses having a nadir area aligned with an area including a point defining the center of gravity of said container; a substantially X-shaped projection formed from a pair of reinforcing ribs projecting from the surfaces of said recesses; and a pair of parallel upper and lower reinforcing rib grooves located entirely in the grip between upper and lower limits of the recesses and extending between the tapered part of one recess and the tapered part of the opposite recess without extending into the recesses.
