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.
What is claimed is: 1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
The tapered parts 8 are inclined slightly inwardly from the rear end of the container body toward the center so that the interval between the both tapered parts 8 is set to a predetermined numerical value for readily grasping the grip 7. For example, assume that the numerical value of the interval between both tapered parts 8 at the rear end of the container body 4 is represented by d and the numerical value of the interval at the center of the container body 4 is represented by d.sub.1. Both values always have a relationship of d&gt;d.sub.1 since the tapered parts 8 are inclined. The concrete numerical values d and d.sub.1 are determined depending upon the shape of the bottle-shaped container 1 such a circular-sectional cylindrical shape or a square- or polygonalsectional cylindrical shape, or the capacity of the container body. For example, in case of d=83 cm, d.sub.1 =77 cm, in case of d=88, d.sub.1 =84 cm, in case of d=77 cm, d.sub.1 =71 cm are experimentally obtained as desired intervals.
A plurality of longitudinal anti-slip strips 9 are formed on the tapered parts 8 so that the faces of the fingers may be readily engaged in case of grasping the grip 7. In addition, two parallel circumferential grooves 9a, 9b are respectively located above and below the recesses 6. The grooves 9a, 9b extend around the perimeter of the container body 4 and increase the overall rigidity of the bottle. In addition, the grooves 9a, 9b increase the buckling stiffness of the bottle when the recesses are grasped. That is, the grooves provide additional rigidity so that the grip 7 is unlikely to collapse (i.e., inward movement of the grip 7 so that d&lt;d.sub.1) under normally expected gripping pressure.
