Abstract
Embodiments herein are generally directed to a flexible pouch for holding a liquid. The pouch includes a front portion and a back portion defining a compartment, a fitment and a frangible seal. The fitment has a body with a pair of wings extending outwardly from a center portion. The center portion has a spout. The front portion, the fitment and the back portion are joined together by a top seal. The frangible seal join the front portion and back portion beneath the fitment. The frangible seal has one end positioned in a portion of the top seal under one of the pair of wings and another end positioned in a portion of the top seal under another of the pair of wings to separate the spout from the contents in the compartment.
Claims22
A flexible pouch for holding a liquid, the flexible pouch comprising:
- a front panel and a back panel sealed to one another via a plurality of peripheral seals to define a compartment receiving a liquid;
- a gap disposed in an upper peripheral seal of the plurality of peripheral seals along an upper edge between the front panel and the back panel above the compartment;
- a fitment positioned within the gap, the fitment including a body with a pair of wings extending outwardly from a center portion, the center portion having a spout;
- the front panel, the fitment, and the back panel joined together by a top seal, the top seal structured and arranged to seal the gap;
- an ultrasonic frangible seal formed through the liquid joining the front panel and the back panel beneath the fitment, the frangible seal having a pair of ends, one end of the pair of ends abutting a portion of the top seal and another end of the pair of ends abutting another portion of the top seal to separate the fitment from liquid in the compartment;
- wherein a top edge of the top seal is disposed below the upper edge;
- wherein a bottom edge of the top seal is non-overlapping with an inner edge of the upper peripheral seal;
- and
- wherein the top seal extends laterally completely along the body of the fitment and beyond the pair of wings.
