Abstract
A particularly small eyedropper or the like is provided, which has a construction such that, when a body thereof is squeezed, an introduction hole thereof can be easily closed to compress air in a space between an inner layer and an outer layer thereof even in the absence of a check valve in the introduction hole, and defectiveness of the introduction hole can be easily checked. To this end, a test hole (19) communicating with an introduction hole (17) via a space between an outer layer bottle (1) and an inner layer bag (16) is provided in an outer layer mouth portion (4). The test hole (19) is closed by the inner layer bag (16) and an inside plug (21) fitted in the mouth portion (4). Further, the introduction hole (17) is provided in a middle portion of a body which is pressed by a finger when the bottle is squeezed. The introduction hole (17) is closed by the finger.
