PURPOSE:To secure complete safety on battery handling by allowing the vessel surface of a small battery, etc., to contain a flavor offering an unpleasant taste which makes a baby want to vomit it when he puts it into his mouth, hereby forcing the baby to vomit out it without swallowing it. CONSTITUTION:In a flat small battery, a negative electrode cap 5 and a positive electrode cap 6 are provided with a corrosion resistant and electrically conductive layer 9 on its surface such that said caps are not dissolved due to acid in the stomach and alkali solution in the bowels in a human body. Further, a flavor offering an unpleasant taste which makes a baby want to vomit it when he puts it in his mouth is absorbed into a resin layer 10 after filling the porous resion layer 10 comprising butyl rubber, chlorinated rubber into a gap between an insulating packing 8 and the negative electrode cap 5. Hereby, it is possible to avoid any danger such as swallowing without relying on the identification by letters difficult to be read by the baby. |
