Benefits of technology

[0006] The present invention solves many of the problems that plague conventional flexible packages and packaging methods. Embodiments of the present invention are directed to a package generally including at least one slit, tie and/or handle membe

Problems solved by technology

Such simplistic tying techniques lack meaningful application in storage and handling of materials such as food, liquid, and the like.
In addition, durability and efficiency is lacking as twist ties can become undesirably detached and lost.
Further, unattached and distinct twist ties are often stored remote from the flexible packages thus imposing potential inconveniences on the user.
Traditional twist ties are also often too short to accommodate storage and handling functions.
Traditional twist ties and techniques lack flexibility for use as handles.

Embodiment Construction

[0031] Referring to FIGS. 1-11, a flexible package 10 in accordance with the present invention is shown. The package 10 generally includes a front panel portion 12, a back panel portion 14 and at least one slit portion 30. Further, a bottom panel portion 15, gusseted or non-gusseted, can be included, especially in those embodiments defining a stand up package. The joining and / or shaping of the panel portions 12, 14, 15, generally define an inner cavity 19 having an adjustable internal volumetric capacity. The panel portions 12-15 are often referred to as “webs.”

[0032] The package panel portions 12-15 are generally constructed of flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylenes laminated with other materials such as nylon, polyester, and other materials known to one skilled in the art. To provide for higher barriers, embodiments can use combination layers or laminates of said materials, and material of the like. Generally, in such e...

Abstract

A flexible package having front, back, and bottom panel portions (preferably gusseted). The front and back panel portions each preferably include longitudinal edges that can be joined together to create respective side seals. Each of the respective side seals can include a slit portion having a slit member. The slit member preferably includes a detachment portion and an anchor portion. The detachment portion of the slit member is detachable from a portion of the side seal to provide a tie or a looped handle for use in tying and / or handling the flexible package. The anchor portion provides support and reinforcement to prevent complete detachment of the slit member.

Description

Related Applications [0001] The present application claims priority to U.S. Provisional Patent Application 60 / 506,912 filed Sep. 29, 2003, entitled, “FLEXIBLE PACKAGE HAVING INTEGRATED SLIT”, which is fully incorporated by reference herein in its entirety.FIELD OF THE INVENTION [0002] The present invention relates generally to flexible packaging and, more particularly, to flexible packaging having at least one slit member formed and integrated therein. BACKGROUND OF THE INVENTION [0003] Conventional flexible packages generally include integrated closeable devices, sliding means, or other devices designed to allow a user to selectively gain access into the pouch or package. Other simpler packages can come with external, non-integrated, twist ties and other tying means. In use, an end user must pinch or compress an open-end portion of the applicable package such that a twist tie is wrapped around the pinched area to provide selective closure. [0004] Such simplistic tying techniques la...
