Dosage package

A dosage package for storing and discharging a liquid, semi-liquid or pasty product, comprising a squeezing thermoplastic container portion and a discharge portion, said container portion and discharge portion being parts of a unitary member, said container portion having a closed all around extending circular cylindrical shaped substantially rigid edge wall portion to which said discharge portion is joined, two opposite side wall portions, at least one of which includes an outwardly durved portion which is compressible to an inwardly similarly curved position so as to measure and discharge a specific dosage when the outwardly curved portion is compressed to the inwardly curved position, and an annular bulged portion forming a juncture between the edge wall portion and the outwardly curved portion so as to form and to limit the outwardly curved portion and also limit the inwardly curved position of the outwardly curved portion, said edge wall portion and said side wall portions having a substantially equal thickness, said thickness being sufficient so that substantially no fluid is diffusable through said wall portions, and so that the side wall portions are imcompressible without said annular bulged portion and said discharge portion being configured so as to prevent discharge of the product stored in the container in the absence of compression of said outwardly curved portion to the inwardly curved position.
