PROBLEM TO BE SOLVED: To lighten the physical burden of a patient who has drunk a press through pack by mistake, by bringing a terpene hydrocarbon compound into contact with a press through pack made from a film or sheet of a cyclic olefin resin to soften or fluidize the olefin resin. SOLUTION: This cyclic olefin resin is obtained by copolymerizing ethylene with a cyclic olefin of formula I (wherein n is 0 or 1; m is 0 or a positive integer; k is 0 or 1; and R1 to R18, Ra and Rb are each a hydrogen atom, a halogen atom, or a hydrocarbon group) or formula II (wherein p and q are each 0 or an integer of 1 or greater; r and s are each 0, 1 or 2; and R21 to R39 are each a hydrogen atom, a halogen atom, a hydrocarbon group or an alkoxy group). A ring-opening polymer of the cyclic olefin of formula I or II, a copolymer thereof, a hydrogenated derivative thereof, or a grafted modification thereof can also be used. A terpene hydrocarbon compound is preferably limonene. When a person has drunk a press through pack(PTP) by mistake, limonene is poured towards the PTP while the PTP stagnating in the esophagus is confirmed, thus softening or fluidizing the resin. |
