A fitment for use as a pour spout for a paper carton or flexible bag for liquids and powders has a flange which may be welded around a hole in the carton or bag. A spout projecting outward from the flange is provided with a removable membrane integral with the interior of the spout. Preferably the membrane is concave. A horizontally disposed pull ring may be attached to the membrane by a connector so that pulling the ring removes the membrane by fracturing the tear line at the juncture of the outer edge of the membrane and the projection. A cap snaps over the spout and may be removed by unscrewing the complementary threads on cap and spout. Optionally, a tamper-evidencing band frangibly connected to the lower edge of the cap skirt engages the exterior of the spout so that the cap cannot be removed without breaking the frangible connection. Various means and methods for detachably securing the fitment to a spud or holder during delivery of the fitment from a chute to the interior of a carton are disclosed.

[ What is claimed is:] [1.] In combination, a fitment holder having a fitment-engaging first portion and a fitment comprising,a spout flange, a spout projecting upward from said flange having an upper and a lower end and an inner and an outer wall surface,said spout having a fitment holder engaging second portion formed to detachably engage said first portion to prevent unintentional disengagement of said holder from said fitment,a membrane sealing off said spout having a line of weakness whereby said membrane may be detached from said spout,at least one of said first and second portions being shaped and dimensioned to relieve any differential from ambient pressure within said spout when said fitment holder is inserted into or withdrawn from said lower end.
