  • Patent number: 8484934
    Abstract: The present disclosure relates to a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces.

  • Patent number: 7478512
    Abstract: The present invention relates to a process used for packaging a product in a web of material that has a zipper attached thereto. The process includes providing a web of material having first and second edges and a zipper including first and second interlocking members. The first and second interlocking members of the zipper are interlocked together. The first interlocking member of the zipper is attached to the web at an intermediate portion of the web between the first and second edges of the web. The second interlocking member has an attachment region that is facing away from the web. One edge of the web is folded away from the zipper and toward the other edge of the web. Unit operations are performed on the zipper to create zipper segments from the zipper while the zipper is exposed. Each of the zipper segments is associated with an individual food package made from the web.

  • Patent number: 7455636
    Abstract: An apparatus for application of zippers to film material 10 comprises an applicator bar 22 for presenting pre-cut lengths of zipper 26 to the film and a heated sealing bar 34 for sealing the pre-cut lengths to the film. The applicator bar, the sealing bar, feed rollers 30a, 30b and a zipper cutter 32 are mounted for movement with the film on a linear motor 14. A pneumatic cylinder 18 raised the application bar towards the film 10. The applicator bar moves in direction C to apply the zipper to the film 10 moving in direction A, then moves with the sealing bar and the film in direction B, away from the film in direction C?, back to its starting position in direction B?, then towards the film again in direction C. A further length of zipper may be fed to the applicator bar at any time after the bar has moved away from the film in direction C? and therefore during an end portion of the forward stroke of the motor, or during its return stroke.

  • Patent number: 7404787
    Abstract: Methods and apparatus for feeding continuous zipper material with sliders to a thermoforming packaging machine that advances the packaging film N package lengths each advance, where N is a positive integer greater than unity. In the packaging machine, pockets are thermoformed in a central zone of the web, while the zipper material is sealed to the web along a lateral zone that is parallel to the machine direction and does not intersect the pockets. A trailing portion of the zipper material in a zipper processing machine is advanced N times every work cycle, one package length per advance. A slider is inserted during each dwell time between advances of the trailing zipper portion. In the zone between the slider insertion device and the zipper sealing station, the zipper material is accumulated each time the zipper material is advanced without concurrent advancement of the packaging material.
