Fitment having removable membrane

In combination, a spud having a fitment-engaging surface and a fitment, said fitment comprising an annular spout flange, a spout projecting upward from said flange having an upper end a lower end and an inner and an outer wall surface,

• a membrane integral with said spout sealing off said spout, said membrane having a peripheral edge joined to said inner wall surface along a circumferential line of weakness,
• said membrane being formed with a serpentine groove extending from a point on said line of weakness inward of said membrane to a terminus remote from said point,
• a connector integral with said membrane extending from said point toward said upper end, and
• a pull tab connected to said connector at a point remote from said point,
• said membrane fracturing both on said line of weakness and said serpentine groove when said pull tab is pulled,
• said fitment being dimensioned to detachably engage said fitment-engaging surface of said spud by friction when said spud is applied to said lower end to prevent unintentional disengagement of said spud from said fitment.
