Patent ID: 8448820

Claim:
A fitment for use on a collapsible bag for dispensing of liquids and semi-solids from the bag, the fitment comprising: (a) a spout comprising a generally hollow cylindrical body having an external surface capable of mating with a cap, the spout having at one end a base portion for securing the spout to the collapsible bag; (b) a cap having an outer collar and an inner collar with the outer collar and the inner collar each having an inner and outer surface, the inner surface of the outer collar and the outer surface of the inner collar forming a cavity adapted to be removably attachable to the spout, the inner surface of the inner collar being capable of attaching to a poppet, the cap further comprising a hollow cylinder section comprising a proximal end and a distal end with each having an inner and outer surface, the cylinder section being fixedly attached at its distal end to the inner collar, the inner surface of the inner collar and the outer surface of the proximal end of the cylinder forming a cavity; (c) said poppet comprising a flexible, non-porous, plastic material or elastomeric material, the poppet comprising an essentially dome-shaped central portion, an upper surface of which is in contact with the proximal end of the cap and which forms a seal with the cap that can be unsealed by a probe, the poppet further comprising a perforated section extending from a lower portion of the dome, the perforated section being curved upwards as compared to the lower portion of the dome so that the perforated section and the dome form a cavity on the upper surface of the poppet, the perforated section further comprising an end which comprises a flange capable of attaching to the inner surface of the inner collar of the cap to form a seal, the dome of the poppet being capable of partially collapsing upon contact of the upper surface of the poppet by a probe, the collapsing dome permitting fluid flow from the spout to travel through the at least one slit of the perforated section; and (d) a slidably removable probe.
