The present invention relates to polymeric packages and, more particularly, relates to polymeric packages having both integrally formed flanges for tying and a second integrally formed closure mechanism such as an adhesive based closure element.

Tack and tie bags

A flexible reclosable package comprises first and second opposing films and first and second closure profiles attached to inner surfaces of the respective first and second films. The first closure profile includes a first closure element and a first lower lateral flange extending downward from the first closure element. The second closure profile includes a second closure element and a second lower lateral flange extending downward from the second closure element. The first and second closure elements are releasably engaged with each other. To render the package child resistant, the first and second closure profiles are free of respective graspable upper flanges extending upward from the respective first and second closure elements. The first and second closure profiles are free of mechanical means operably coupled thereto such that the first and second closure profiles are disengaged by grasping the first and second films below the first and second closure elements and pulling the first and second films in opposite directions.

Child resistant packaage

A rigid reclosable package comprises a rigid tray and a flexible cover. The tray includes a bottom, side walls and a flange extending from upper portions of the sides walls and around the periphery of the tray. The flange has a tray opening edge on which a first closure profile is attached. A second closure profile is attached to the flexible cover opposite the first closure profile. The first and second opposing closure profiles are adapted to releasably engage each other. The cover is permanently attached to the flange except along the tray opening edge.

Rigid reclosable packaging

A reclosable bag arrangement comprises a bag and an external zipper clip. The bag includes first and second opposing films. The external zipper clip includes first and second opposing closure profiles adapted to releasably engage each other. Each of the first and second closure profiles has opposing ends, and the opposing ends of the first closure profile are attached to the respective opposing ends of the second closure profile. The first and second opposing films extend through the zipper clip between the first and second closure profiles. The zipper clip closes the bag in response to interlocking the first and second closure profiles with the first and second films interposed therebetween. The zipper clip is not heat-sealed or adhered to the bag such that the zipper clip is separable from the bag in response to disengaging the first and second closure profiles. Since the zipper clip may be separated from the bag, the material of the zipper clip need not be heat-sealable to the bag and the zipper clip may be reused with other bags.

A recloseable profile strip designed to eliminate the slipping of the top web with respect to the bottom web in the recloseable profile strip of a recloseable package and remove the need for a tack seal. The present invention utilizes a joining web to join the top web and bottom web of the recloseable profile strip of a recloseable package. The recloseable profile strip is extruded through a die from molten material in a flat, single strip. In the double recloseable profile strip of the present invention, the first and second top webs each having an interlocking member flank the bottom web having two interlocking members. A thin, first joining web joins the the margin of the first top web to a first margin of the bottom web, and a thin, second joining web joins the margin of the second top web to the second margin of the bottom web. The single strip is then cooled. A machine positions the top webs above the bottom webs, and a 'mater' interlocks the interlocking members of the top webs with the interlocking members of the bottom web. The strips of double recloseable profile strip can then be used with conventional form-fill-seal machinery to make the recloseable packages.

A closure system for a film wall package includes profile strips having a reclosable seal of the interlocking type, flange elements and, adjacent the reclosable seal, an adhered strip of peelable material. The peelable material and the profile strip may be co-extruded. With packaging film attached to the profile strips, typically to the flange elements, the resulting product may be used in a horizontal form, fill and seal operation, at which time the reclosable elements are mated and a peel seal is formed. The peel seal may be disposed on either side of the reclosable seal with respect to the interior of the package. The benefits of both peel seals and reclosable seals may be obtained by using optimum materials for those elements while, at the same time, allowing the use of a different material for the walls of the package.
