PURPOSE: Provided is a flexible pouch fitment structure, whereby it is possible to simultaneously contact a package film, thus sealing the film surface at the top of the pouch at the same time as attaching the fitment. CONSTITUTION: The flexible pouch fitment(22) includes a pair of side walls(26,28), the side walls(26,28) each having a center portion(30,32) comprising diametrically opposed segments of a common cylinder and straight segments(34,36,38,40) tangent to and blending respectively into the cylindrical segments(30,32), the side walls(26,28) being joined together at both ends thereof thereby forming a canoe shape; a cover joining the top edges of the canoe shape and extending at both ends of the canoe shape between the cylindrical segments(30,32) and the joined ends, the cover being the only support for the side walls(26,28); and a thin fin(42,44) at each end of the joined side walls, the fins(42,44) comprising extensions of the canoe shape. |
