Abstract

Abstract A blow-moulded bottle-shaped container (21) of biaxially-­oriented synthetic resin having an integrally-moulded neck (23) at the top of a cylindrical body (22) of the container, there being a pair of inwardly-depressed recesses (24) in the cylindrical wall of the cylindrical body at opposite sides thereof with the minimum spacing between the recesses (24) being at their deepest parts (25) so that a portion of the cylindrical wall between the recesses (24) forms a grip (27) as a result of the recesses, wherein at least one laterally-­extending reinforcing rib (28) projects concavely in an arch-­shape bent inwards to cross both tapered walls (26) of each of the recesses.

Independent Claim 109 words
A blow-moulded bottle-shaped container (21) of biaxially-­oriented synthetic resin having an integrally-moulded neck (23) at the top of a cylindrical body (22) of the container, there being a pair of inwardly-depressed recesses (24) in the cylindrical wall of the cylindrical body at opposite sides thereof with the minimum spacing between the recesses (24) being at their deepest parts (25) so that a portion of the cylindrical wall between the recesses (24) forms a grip (27) as a result of the recesses, characterized in that at least one laterally-­extending reinforcing rib (28) projects concavely in an arch-­shape bent inwards to cross both tapered walls (26) of each of the recesses.
Claim 2
Dependent Claim 109 words
A blow-moulded bottle-shaped container (21) of biaxially-­oriented synthetic resin having an integrally-moulded neck (23) at the top of a cylindrical body (22) of the container, there being a pair of inwardly-depressed recesses (24) in the cylindrical wall of the cylindrical body at opposite sides thereof with the minimum spacing between the recesses (24) being at their deepest parts (25) so that a portion of the cylindrical wall between the recesses (24) forms a grip (27) as a result of the recesses, characterized in that at least one laterally-­extending reinforcing rib (28) projects concavely in an arch-­shape bent inwards to cross both tapered walls (26) of each of the recesses.
Claim 3
Dependent Claim 31 words
A container according to claim 1, characterized in that the reinforcing ribs (28) are aligned at such a predetermined interval that a finger of a human hand can enter the interval.
Claim 4
Dependent Claim 26 words

Claim 6
Dependent Claim 34 words
A container according to claim 1, characterized in that the reinforcing ribs have a length substantially equal to a lateral length of the recesses and a height less than the depth of the recesses.
