A flexible plastic fitment for providing spouts for pouches formed of sheet material. The fitment includes a pair of opposed side walls each having a center portion formed from diametrically opposed segments of a common cylinder and straight segments that blend respectively into the cylindrical segments on opposite sides of the common cylinder. The side walls are joined together at both ends thereof to form a canoe shape. A cover, which provides the only support for the side walls joins the top edges of the canoe shape and extends at both ends of the canoe shape between the cylindrical segments and the joined ends. A thin fin extends from each end of the joined side walls. A method of and apparatus for attaching the fitment by distending the side walls outwardly while urging the sheet material toward the side walls is also disclosed.

Methods of making slide-zippered reclosable packages are provided. In one embodiment, a pair of opposing film extensions are provided on each package between which a zipper and slider are attached. In another embodiment, sliders are inserted on to zippered packages output from a form-fill-seal machine or the like. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and then a slider is inserted on to the zipper. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and a slider is inserted on to each zipper, either before or after zipper sealing.

A fitment has walls with a spout aperture therebetween. Reduced wall thickness results in a reduced amount of plastic in the fitment. An alternative embodiment uses radially extending meltable fins. During installation in a sealing apparatus, a heated mandrel engages the inner diameter of the spout aperture thereby pre-heating and physically supporting the fitment during the installation process. The heated mandrel typically engages the fitment at least one cycle prior to be installed. The fitment may be canoe-shaped.

A slide zipper assembly comprising an interlocked zipper and a slider is provided. The zipper has a first profile and a second profile. The profiles have arms ending in hooks that are engaged when the zipper is in a closed position. The slider is disposed for movement along the zipper. The slider has an opening end and a closing end. At the opening end the slider has a separator that extends downwardly to engage a profile arm to bend the same so that its hook disengages from the hook of the opposite profile.

A zipper strip for a reclosable package having a transverse zipper is provided. The zipper strip comprises a male interlocking profile and a female interlocking profile. Each profile includes an interlocking member and an integral web which defines a leading flange. The leading flanges are sealed to thermoplastic film material which is used to make the reclosable packages and to each other. A perforation extends along the length of the zipper strip so that the profiles can be readily separated.

Packages being produced on a form, fill and seal machine as provided with transverse zippers inserted thereinto through a fin seal gap. Pairs of fin sealing bars are separated by a gap to produce the fin seal gap. The fin seal gap is opened, perhaps by vacuum means, and a zipper probe inserts a zipper having a web into the tube of plastic sheet material being formed into bags. The web of the zipper is sealed to the plastic sheet material, and the zipper probe withdrawn from the tube. Cross seal jaws seal both transverse ends of the package, a knife separates each package from that previously made, and a fin gap sealer seals the fin seal gap to complete the manufacture.
