A container having a tubular sidewall. A closure is mounted to one end of the sidewall by molding in situ. The sidewall end portion is provided with an array of circumferentially spaced through openings, and the closure includes a U-shaped connecting portion having a pair of spaced legs on opposite sides of the end portion, with securing portions extending between the legs through the openings. The closure is injection molded so as to clamp the end portion of the tubular element between the legs and sealingly connect the closure thereto. At the opposite end, a connecting ring is formed in situ on the end portion of the tubular element in the same manner as the connecting portion of the first described closure. The connecting ring includes a radially outwardly opening annular recess adapted to receive an inturned complementary flange on a removable closure member. The flange is split and the removable closure member is provided with a pair of tabs. Different forms of constricting and locking structure for cooperation with the tabs are disclosed, including such structure adapted to be utilized without the need for tools.
