This creation is a kind of cup seat structure improvement,Its fan substrate body left side,Combination is mutually sticked together in the engaging portion of right two sides,It is in a plane fan-shaped by combining tapered fan substrate body to close cutting die line portion to flatten folding and close with respect to what folding,User's finger pulls recess set by what rising wood when what is to be unfolded,And cutting die line portion is closed in the folding of micro- force compacting two side of fan substrate body,It closes folding and is launched into three-dimensional cone cell in the fan substrate body stabilization of plane fan-shaped,And completing to stick together and flatten folding and close when fan substrate body what automation processing is in a plane fan-shaped,Simplify overall processing time-histories and increase production capacity,The effect of to reach structural stability and good ease of use.本創作係一種杯座結構改良，其扇型基板體左、右二側之結合部相互黏著結合，藉由結合呈錐狀之扇型基板體相對於摺合刀模線部壓平摺合呈一平面扇狀，於欲展開時使用者手指扳於上緣部所設凹口，並微施力壓制扇型基板體二側之摺合刀模線部，使摺合呈平面扇狀之扇型基板體穩定展開成立體錐狀，且該扇型基板體於自動化加工時即完成黏著及壓平摺合呈一平面扇狀，簡化整體加工時程並增加產能，以達結構穩定性及使用便利性佳之功效。
