A container (20) disclosed includes a receptacle (22) and a cover (24) each of which includes a unitary member (26,28) molded from plastic. A helical thread (44) on the upper end of the receptacle side wall (30) and a helical thread (58) on a downwardly projecting lip (50) of the cover are engaged with each other in mating relationship by either threading of the cover onto the receptacle or by downward movement as the receptacle side wall and the cover lip flex to permit such engagement by a snap action. A retainer (46) on the receptacle side wall receives the lower edge (52) of the cover lip and a retainer (60) on the cover receives the upper edge (36) of the receptacle side wall so as to maintain the mating relationship of the threads with the cover in its closed position. The container has particular utility for use as a paint container especially when utilized with specific constructional features disclosed.

摘要:
To provide a container for storing a biological tissue capable of storing the biological tissue with an immersed state with its original form being maintained. A container for storing a biological tissue comprises an inner container used to store the biological tissue, and an outer container which seals and accommodates the inner container. The outer container comprises a gas permeation part which allows sterilization gas to flow into the inner container from outside, or the outer container and the inner container are made of a material which allows permeation of a radioactive ray or an electron beam. The inner container comprises a container having an upper opening and capable of accommodating the biological tissue and a solution which hydrates the biological tissue, and a lid part which closes the opening. The outer container and the inner container are pierceable by an injection needle which injects the solution from outside.
