A method of making reclosable packaging utilizes a longitudinally extending web of film material having cutouts therein. A length of zipper strip substantially half the width of the web and having an attached slider is applied transversely across the web of film material with the slider positioned in the cut out. The web is folded longitudinally with the zipper attached to the web and the slider positioned in the cut out. The edges of the web are brought together longitudinally and seamed to form a tube. The opposite ends of the tube are sealed to form the package. The resultant bag has the slider seated in the cut-out where it is readily visible to a consumer.

A reclosable package having a front wall ( ), a rear wall ( ), bottom ( ), top ( ), and first and second sides ( ). A zipper ( ) extends across the package top between the sides with a slider ( ) disposed along the zipper between a zipper fully open position when the slider is at the first side ( ) and a fully closed position when the slider is at the second side ( ). A side seal ( ) on the first side ( ) joins the front wall ( ) to the rear wall ( ) and extends between the bottom ( ) and the zipper ( ). The side seal ( ) further extends toward the second side ( ) for a distance at least as long as the length of the slider ( ). When the slider ( ) is in the zipper fully open position it parks above the side seal ( ) and out of the mouth of the package ( ) leading to a product cavity ( ).

An apparatus ( ) for feeding sliders ( ) from a source of sliders to the slider insertion area ( ) of at least two slider insertion devices ( ). A sensor ( ) on a sender track ( ) detects a lack of sliders ( ) in the sender track. A signal is sent from the sensor ( ) to actuate a vibratory bowl ( ) of sliders ( ) and a plunger ( ) to open a passage, thereby releasing the sliders ( ) to a sender track ( ). When a sensor ( ) detects a lack of sliders ( ) in a loading rack ( ) or a slider insertion area ( ), the sensor ( ) signals a plunger ( ) and a pneumatic valve ( ) to open a passage to provide an air blast, thereby launching the sliders ( ) onto the slider insertion area ( ) of each slider insertion device ( ). A directional gate ( ) sends the sliders ( ) to either sender track ( ) prior to launching to either slider insertion device ( ), or a directional gate ( ) sends the sliders ( ) to either slider insertion device ( ) after launching of the sliders ( ).

An ultrasonic welding assembly comprising a horn, an anvil and an anvil cover. The horn comprises a generally T-shaped flattening surface and a rail projecting forward of the flattening surface. The rail is shaped to serve as a dam for flowing thermoplastic zipper material during stomping of slider end stops. The horn further comprises a plurality of vertical energy directors designed to direct ultrasonic energy into the mass of zipper material and deflect flowing zipper material toward the dam. The horn further comprises first and second recesses located on opposite sides of a stem of the T-shaped flattening surface. The anvil cover overlies opposing portions of the anvil and comprises a T-shaped cutout. The T-shaped flattening surface of the horn fits in the T-shaped cutout of the anvil cover. The resulting zipper has slider end stops located at opposing ends.

A method and a system for forming slider end stops on a zipper tape that comprises first and second interlockable zipper parts. The method comprises the following steps: (a) transmitting sufficient ultrasonic wave energy into first and second areas of the zipper tape to cause the first and second interlocked zipper parts to deform and fuse in the first and second areas, the first and second areas being separated by a gap; and (b) applying sufficient heat and pressure onto a third area of the zipper tape to cause the interlocked zipper parts to deform and fuse in the third area, at least part of the third area being located between the first and second areas in the gap. The first and second areas do not impinge upon the zipper rails. The third area does impinge upon the zipper rails. Thus the zipper rails are deformed in the third area, but not in adjacent areas located below and contiguous with the first and second areas.

The reclosable plastic bag is formed by opposing panels of web with four sides sealed. A zipper is sealed within the bag so that a first zipper profile is sealed to a first opposing panel and a second zipper profile is sealed to a second opposing panel. A slider engaging the zipper profiles in a closed position protrudes from an opening in at least one of the opposing panels and may be further secured in place by a label. The slider cannot be moved from the position wherein the zipper profiles are closed to the position wherein the zipper profiles are open prior to the user tearing a perforated or otherwise weakened line across the panels. When this tear is made, it is unmistakable and intuitive evidence that the bag may have been previously opened and depending upon the circumstances, possibly tampered.

A reclosable package has a first wall and a second wall opposite to the front wall A first zipper profile including a first interlocking member is attached to the first wall and a second profile having a second interlocking member, engageable with the first interlocking member, is attached to the second wall. A slider is positioned on the profiles for movement along the profiles from side to side of the package. Package material is provided which must be removed or ruptured to permit operation of the slider or to provide access to the package contents. In either event, the steps needed to permit the initial access to the package contents leave clear evidence for a consumer that the package has been opened.

A method for making a reclosable bag ( ) with gussets ( ) in which a zipper profile ( ) is attached to bag-making film ( ), while leaving side margins ( ) of the film. The film ( ) is folded as a tube ( ). Gusset-forming wheels ( ) indent the tube ( ) to form the side gussets ( ). The side gussets ( ) are sealed to the tube ( ) and/or the zipper profile ( ) with the profile sealed to the tube. The tube ( ) is sealed and cross-cut to form the bag ( ). In an alternative method, lengths of tubular gusset material ( ) are positioned on a lower web ( ) of film ( ) transverse to a bag-forming direction. A zipper ( ) is sealed in the bag-forming direction to the webs ( ), and the gusset material ( ). The webs ( ) and the material ( ) are sealed to each other to form an end seal ( ) as well as cross-cut and sealed to form the gussets ( ) of a reclosable bag ( ). The webs ( ) may be sealed above the zipper ( ) to form a tamper-evident feature ( ).
