Abstract: The present disclosure is directed to a process. In an embodiment, the process includes (A) providing a flexible container having (i) a body, and (ii) a neck. The process includes (B) positioning a fitment into the neck. The fitment is composed of a polymeric material and includes a top portion and a tapered base. The tapered base extends from the top portion to a base end. The top portion has a top inner diameter (TiD) and the base end has a base end inner diameter (BEiD). The BEiD is less than the top inner diameter, (TiD). The process includes (C) heating the tapered base to a malleable state and (D) inserting a mandrel into the fitment. The mandrel includes an expandable collar. The process includes (E) expanding the expandable collar radially outward to contact an inner surface of the tapered base. The process includes (F) increasing, with the expanding, the inner diameter of the base end to a stretched base end inner diameter (sBEiD). The sBEiD is greater than the BEiD.

Abstract: The present disclosure provides a flexible container having four panels—a front panel, a rear panel, and opposing gusseted side panels. The front panel bottom face includes a first line defined by the inner edge of a first peripheral tapered seal and a second line defined by the inner edge of a second peripheral tapered seal. The first line intersects the second line at an apex point in a bottom seal area. The front panel bottom face has a bottom distalmost inner seal point on the inner edge and the apex point is separated from the bottom distalmost inner seal point by a distance from 0 mm to less than 8.0 mm.

Abstract: A fitment has an axis and a registration feature. The fitment is sealed within a bottle neck in a position in which the registration feature has a predetermined orientation to the bottle neck rotationally about the axis. Preferably, the fitment has a screw thread defining a limit of rotation for a bottle cap to be screwed onto the fitment. The registration feature has a predetermined orientation to the screw thread rotationally about the axis, whereby the limit of rotation also has a predetermined orientation to the bottle neck rotationally about the axis.

Abstract: A plastic film preform is expanded to form a container. The preform has a longitudinal axis that extends from an open top to a closed bottom. The preform is pressurized with a first pressure sufficient to cause side walls of the preform to expand outwardly and the bottom of the preform to be drawn inwardly thereby reducing a length of the preform along the longitudinal axis. Side molds are closed around the side walls of the preform, the closed side molds being larger than the expanded side walls. A bottom mold is closed to be adjacent to the bottom of the preform after pressurizing the preform with the first pressure. The preform is pressurized with a second pressure sufficient to expand the preform to fill the closed molds. The preform is thereby significantly stretched in a direction perpendicular to the longitudinal axis and minimally stretched along the longitudinal axis.

Abstract: A flexible container includes a panel structure of flexible web material, including panels that are adjoined to define a pouch. The pouch has a top opening with a fitment, and is expandable from a collapsed, unfilled condition to an expanded, filled condition. When the pouch is in the filled condition and resting on a flat surface, the panel structure supports the pouch in an upright orientation in which the fitment opening faces upward. The panel structure also provides the pouch with a flat footprint upon which the pouch overlies the flat surface. The flat footprint is defined in part by the pouch and in part by the lower handgrip in a condition folded beneath the pouch.
