PROBLEM TO BE SOLVED: To improve an opening part of a synthetic resin beverage container which is opened by twisting and cutting an upper suction port pipe, protect beverage stored in the container and improve a container structure. SOLUTION: This container is constituted such that a knob having a tubular suction port opened and protruded upward of a packaging container with transparent beverage and colored beverage such as soft drinks and tea or the like is provided with a thick wall part to cause it to be easily twisted with a finger tip force. Its bottom surface is provided with a stable bulged-out segment and a body structure to have such a constitution as shown in a sectional view of Fig.6 so as to prevent the four-layer structure from melting out by the molding technology and filled liquid from being oxidized. |
