<p>This aims to create such a shape of an evacuation absorbing panel in a synthetic resin bottle body as can suppress a bulging deformation accompanying a hot charge, without deteriorating an evacuation absorbing function. In the synthetic resin bottle body, the evacuation absorbing panels are depressed and formed in the trunk of the bottle body in parallel in the circumferential direction. In the transverse center portion of the evacuation-absorbing panel, vertical grooves are formed to perform a function as a starting point for the depressed deformation at the evacuation time. The vertical grooves are made deeper upward and downward from the vertical center portion of the evacuation-absorbing panel.</p> |
