A device for closing a spout of a flexible container is provided. The device includes a connection tube and a sealable cap having an outer casing member with a lower, outer circumferential surface, an attachment member annularly positioned on a portion of the lower, outer circumferential surface, and an inner casing member having an inner casing sidewall and a bottom disc-shaped occlusion plate defining a cylindrical void space configured to receive a connection tube. The plate can be integrally connected to the inner casing sidewall via a thin-wall section sized to break by the insertion of an insertion edge of the connection tube. The device can also include an overcap sized to mate to the sealable cap.
