<P>PROBLEM TO BE SOLVED: To provide an unsealing assisting implement for a cup-type vessel, which enables a mouthpiece air inlet to be easily, noiselessly and smoothly formed in a seal lid, and which can be attached as a mouthpiece for drinking to a cup. <P>SOLUTION: This unsealing assisting implement is provided with an overcap 6 which can be liquid-tightly attached to the cup, and one or more cutters 7 which are displaceably connected to the overcap 6 and which can open the seal lid 5. The cutter 7 is connected to the overcap 6 via an inverting hinge 22. In a state in which the overcap 6 is attached to the cup-type vessel 2, the inversion of the inverting hinge 22 enables the cutter to be displaced from a reference position where a cutting edge 31 is brought into noncontact with the seal lid 5, to an incision position where the cutting edge makes the seal lid 5 cut open. <P>COPYRIGHT: (C)2008,JPO&INPIT |
