| 摘要 | PURPOSE: To simplify starting operation of duration display by folding and holding a bellows part in the vicinity of an open end of main vessel in which a substance to be dyed is stored, by closing off a hole provided to a sub-vessel which seals and stored, dyeing substance at a place lower than the bellows part, and by fixing together the main and sub-vessels at their top ends. CONSTITUTION: The duration displaying body of this invention consists of a cylindrical main vessel 2 storing a substance to be dyed, and a cylindrical sub- vessel 3 which is inserted and engaged into an open end of the main vessel 2, and stores and seals a dyeing substance. In the vicinity of the open end of main vessel 2, a bellows part 6 is folded and held, and a hole 4,4' provided to the sub-vessel 3 is closed off by a barrel wall 5 placed below the bellow part 6. The main vessel 2 and the sub-vessel 3 are fixed together at their top ends. When in use, the bellows part 6 of the main vessel 2 is extended, then the hole 4,4' is released for the dyeing substance to proceed to the side of substance to be dyed and therewith display of duration is commenced by contact of the both substances. In this way, operation to start display can be simplified. COPYRIGHT: (C)1992,JPO&Japio |
