A disk-like support member is dimensioned to be attached to a spout end of a thermoplastic tube in snap fit engagement. A tear band is attached to the member periphery by weakened regions. A cap is hinged to the support member to close the spout. The tube has an annular groove. The tear band has a first rib which locks to the annular groove of the tube and a second rib which engages a recess in the cap to lock the cap to the tear band in a closed condition. The locking arrangement is such that the tear band must be removed to remove the support member from the tube or to open the cap.
