Detailed Description

Distribution aisles for sending and receiving goods typically use transportation documents to route, sort and track the various goods that flow through the aisles. Shipping documents include, for example, air bills of lading, shipping labels, invoices, packing lists, and other documents relating to the goods. The shipping documents are placed within bags that are attached to a receiving surface, such as a package, box, carton or other container, for shipping through the passageway. To ensure proper sorting, tracking, import/export and final delivery, it is important to keep the transport documents together with the goods throughout the entire journey through the aisles.

During transport, the bags may be opened and closed (i.e., resealed) multiple times before the goods reach the final destination (particularly for international goods). For example, the shipping documents may be removed from the bags, one at a time, by the carrier at various points of operation for shipping through the aisles, and/or by customs personnel at export and import ports. At the destination, the recipient opens the bag and removes the shipping document. Thus, the bag may employ a resealable flap or cover to provide a means of accessing the shipping documents.

Such resealable flaps may fail during shipping because, for example, the flap is rubbed open (i.e., unsealed) or the flap is completely torn from the pouch. The failure may be due to movement of the container containing the goods and/or interaction with other containers and sorting equipment (e.g., conveyors and slides). If the flap fails, the shipping documents within the bag may slip out of the open bag, which may result in the goods being incorrectly sorted, lost, kept at customs, and/or delayed delivery.

Embodiments of the present disclosure generally relate to resealable packaging manifest bags (i.e., package inventory envelopes). More particularly, embodiments of the present description relate to resealable, self-attaching packaging manifest bags that are particularly adapted to receive and contain shipping documents and attach to a receiving surface. Embodiments include a protective lip forming a portion of the pocket and providing a redundant barrier in addition to the resealable flap to accommodate shipping documents placed within the pocket. The protective lip provides a series of mechanical, safety and passive protection to the opening of the pocket and prevents transport documents placed in the pocket from sliding out through the opening when the closure produced by sealing the resealable flap fails.

In some embodiments, the resealable package booklet includes two panels or sheets, a resealable flap and a protective lip. These components are made of thin, flexible materials and are heat sealed or otherwise adhered to one another to form pockets for the placement of shipping documents. The protective lip is attached to the back panel such that a lower portion of the protective lip covers the top panel directly below the pocket opening. The front flap is attached to a protective lip at the top edge of the package booklet pouch. An adhesive material (e.g., a pressure sensitive material or a contact sensitive material), which may be in the form of a strip, is applied to a portion of the top surface of the top panel. The flap may be sealed, opened, and then resealed to the top surface of the top panel by an adhesive material. When sealed to the top surface of the top panel, the flap extends from the attachment edge to cover the protective lip, the opening of the pocket, and a portion of the top panel. A lacquer material, such as silicon, may be applied to the bottom surface of the flip to prevent transfer of adhesive material between the top surface of the top panel and the bottom surface of the flip. In addition, a coating of adhesive material is applied to the rear surface of the rear panel and is used to attach the invoice bag to the receiving surface. One or more removable release liners are attached to the back panel by the coating of adhesive material and can be removed to attach the manifest bag to the receiving surface by the coating of adhesive material.

Turning to the drawings, fig. 1,2 and 3 show a front view of a preferred embodiment of a resealable packaging bag 100, fig. 4 shows a perspective view of the front side of the preferred embodiment, fig. 5 and 6 show a rear view of the preferred embodiment, fig. 7 shows a perspective view of the rear side of the preferred embodiment, and fig. 8 and 9 show a side view of the preferred embodiment of the resealable packaging bag.

Resealable package manifest bag 100 comprises four plastic sheets (flap 110, protective lip 120, front sheet 130 and back sheet 150), adhesive strip 140, backing adhesive 160 and release liners 170 and 172. In a preferred embodiment, these plastic sheets are at least partially made of a transparent (or translucent) flexible plastic. Preferred plastic materials include polyethylene, polypropylene and polyethylene terephthalate (PET). In various embodiments, the protective lip sheet 120, the front sheet 130, the back sheet 150, and the flap sheet 110 are made of polyethylene film.

The back sheet 150 and the front sheet 130 are joined at their respective side and bottom edges to form a bottom 182 of the pocket 180 between the back sheet 150 and the front sheet 130. The bottom 182 of the pocket 180 is formed such that the top edge 152 of the back sheet 150 extends beyond the top edge 132 of the front sheet 130 to form an opening 188 (see fig. 4).

The protective lip 120 and the back sheet 150 are connected at their respective top edges. In addition, the side edges of the protective lip 120 are connected to the tops of the respective side edges of the back sheet 150 and the tops of the respective side edges of the back sheet 130. The bottom 124 of the protective lip 120 covers the top edge 132 of the front panel 130 and extends just below the opening 188. The protective lip 120 and back sheet 150 form the top 184 of the pocket 180.

The flip cover sheet 110 and the protective lip 120 are connected at their respective top edges such that the top edge of the protective lip 110 is located between the top edge of the flip cover sheet 120 and the top edge of the bottom sheet 150. Resealable adhesive strip 140 is adhered to the outer surface of front panel 130 proximate bottom edge 122 of protective lip 120. The bottom of flap 110 may be sealed to front panel 130 by resealable adhesive tape 140. When sealed to front panel 130 by resealable adhesive strip 140, flap 110 forms a closure over opening 188 (see fig. 1,2,4 and 8) and extends from the top edge of resealable packaging bag 100 to cover protective lip 120, opening 188 and the top of front panel 120. The sealed packaged manifest bag 100 (see fig. 2) can be opened by peeling the flap sheet 110 and breaking the seal between the flap sheet 110 and the front sheet 130 along the adhesive strip 140. The shipping documents may then be inserted into the pockets 180 through the openings 188. The packaged manifest bag 100 can then be resealed by applying pressure to the bottom of the flap 110 along the resealable adhesive strip 140.

In various embodiments, as described above, the connections formed between the respective edges of the four plastic sheets (flap 110, protective lip 120, front sheet 130 and back sheet 150) of resealable package booklet bag 100 are created by heat sealing. Heat sealing is a process of bonding materials together by applying heat and pressure together. In the preferred embodiment shown in fig. 1-9, the overlapping edges of the plastic sheets are aligned. Pressure and heat are applied near the edges to be bonded using heating elements that melt the plastic and merge the plastic sheets together. Various machines for performing heat sealing may be used and operated by AC or DC power.

In other embodiments, the connections between the four plastic sheets of the resealable packaging bag 100 are formed by permanent adhesives or a combination of heat sealing and permanent adhesives. Preferred permanent adhesives include acrylic adhesives and hot melt adhesives. A primary characteristic distinguishing permanent adhesives from resealable adhesives (e.g., for forming the resealable adhesive strips 140, see below) is that once the bond of the permanent adhesive is broken, the adhesive no longer functions as an adhesive (i.e., the permanent adhesive is not resealable). Moreover, the bond strength of permanent adhesives is typically much higher than that of resealable adhesives. For example, the bond strength of permanent adhesives is much higher than the force required to open the resealable adhesive without failure, separation, or peeling.

The resealable adhesive strip 140 is preferably deposited in a width of between 0.25 inches and 0.50 inches in a strip as shown in fig. 2-4, although other dimensions may be used. The resealable adhesive strip 140 may be made of a pressure sensitive or contact adhesive material, such as acrylic, natural and/or synthetic rubber. Preferably, the material used to form the resealable adhesive strip 140 has sufficient peel strength, which is the average load per unit width of the adhesive line required to separate the adhesive material (e.g., front panel 130 and flap 110), wherein the separation angle is 180 degrees. In a preferred embodiment, the resealable adhesive strip 140 has sufficient adhesive strength to withstand the rough shipping environment to prevent the flap 110 from being frictionally opened and/or torn. At the same time, the flap 110 can still be opened under the normal efforts of the person needing to open the resealable packaging bag 100 (i.e., the force required to separate the flap 110 from the front panel 130 along the resealable adhesive strip 140 does not damage or cause the plastic to tear). The material used to form the resealable adhesive strip 140 leaves little or no residue on the bottom surface of the flip top sheet 110 after each opening and resealing of the resealable packaging single serve bag 100. The bottom surface of the flip sheet 130 adhered to the resealable adhesive tape 140 may be coated with a lacquer material, such as silicone, to prevent the adhesive from transferring from the top surface of the front sheet 130 to the bottom surface of the flip sheet 110.

In an alternative embodiment, an adhesive tape release liner (not shown in the figures) may be attached to the adhesive tape 140. The adhesive tape release liner may be formed from a paper material coated with a release agent such as silicone. By sealing the flap 110 to the front panel 130 via the exposed adhesive tape 140, the adhesive tape release liner will be removed prior to closing the resealable packaging bag 100.

In various embodiments, the resealable adhesive tape 140 may be a double-sided tape (i.e., a plastic tape/carrier) having a permanent adhesive, such as an acrylic adhesive or a hot melt adhesive, on one side and a resealable adhesive on the other side. In such embodiments, the permanent adhesive side of the tape may be adhered to the outer surface of the front panel 130 proximate the bottom edge 122 of the protective lip 120, leaving a resealable adhesive side to form a resealable closure with the flap 110.

In an alternative embodiment, resealable adhesive strip 140 may be adhered to the bottom surface of flip sheet 110, and a lacquer material applied to the outer surface of front sheet 130. In other alternative embodiments, adhesive tape (e.g., adhesive tape 140) may be applied to both surfaces (i.e., the outer surface of front panel 130 and the bottom surface of flip panel 110).

The backing adhesive 160 may be coated on the outside of the backsheet 150 (see fig. 6), and preferably covers most, if not all, of the outside of the backsheet 150. In an alternative embodiment, the backing adhesive 160 is applied along an edge or strip on the outside of the backsheet 150. The backing adhesive 160 is formed of an adhesive material such as a hot melt adhesive.

Release liners 170 and 172 are attached to the outer surface of the backsheet 150 by the backing adhesive 160 to cover and protect the backing adhesive 160 until the resealable packaging manifest bag 100 is ready for attachment to a receiving surface (see fig. 5-9). The release liners 170 and 172 may be formed from a paper material coated with a release agent such as silicone. The release liners 170 and 172 can be removed, at which point the resealable packaging manifest bag 100 can be attached to a receiving surface of a shipping container (e.g., package, envelope, or box) using the backing adhesive 160. In an alternative embodiment, a single release liner (i.e., a single sheet of paper material coated with a release agent such as silicone) may be used for both release liners 170 and 172.

In an alternative embodiment, the bottom edge of the protective lip is near or against the top of the front panel (i.e., at the opening of the pocket) so that the bottom of the protective lip does not cover the opening of the formed pocket. In other alternative embodiments, a resealable packaged manifest bag having front and back panels of equal or nearly equal size is formed by joining the respective top, bottom and side edges. In these embodiments, an opening is formed in the front panel by, for example, slitting or cutting between the top edge of the front panel and the adhesive tape. The opening extends from one side edge adjacent the front belt to the other side edge.
