Flexible Container with Closure and Method
A flexible container is formed from a flexible container body formed from a flexible material, the flexible container body having at least one end opening. A pair of spaced apart elongated flexible closure members is coupled to the sides of the flexible container body generally along the length or portion of the length of the flexible container body. The flexible closure members are deformable and configured to facilitate selectively closing of the end opening of the flexible container body by twisting together the flexible closure members along with a portion of the flexible container body so that the flexible closures generally stay in a twisted configuration. The end opening of the flexible container body is selectively opened by untwisting the flexible closures from the twisted configuration.
This application claims priority to U.S. Provisional Patent Application No. 60/891,980, entitled “Closure for Flexible Container,” filed Feb. 28, 2007, which is herein incorporated by reference in its entirety.
BRIEF DESCRIPTION OF THE DRAWINGSFor a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying figures, in which:
Referring to
In the embodiment shown in
The container body 12 may be formed from a variety of different materials that are relatively thin and flexible so that the container body 12 is generally flexible and collapsible. The flexible body 12 may be formed from paper, fabric or a plastic or polymeric sheet material. In particular, the flexible body 12 may be formed from polymer materials, such as polyethylene (e.g. HDPE, LLDPE, etc.), polypropylene, nylon, etc. or those materials often used to form those containers referred to as “poly bags” used for storing bread and other food items, such as baked goods, ice, popcorn, produce, etc. The walls of the flexible body 12 may be a variety of different thickness, but typically will be from about 0.001 mil to about 10 mil or more depending upon the purpose of the container.
It should be noted that the description and embodiments described are presented solely for the purpose of illustrating the invention and should not be necessarily construed as a limitation to the scope and applicability of the invention. In the description, each numerical value should be read once as modified by the term “about” (unless already expressly so modified), and then read again as not so modified unless otherwise indicated in context. Also, in the description, it should be understood that a value or range listed or described as being useful, suitable, or the like, is intended that any and every value within the range, including the end points, is to be considered as having been stated. For example, “a range of from 1 to 10” is to be read as indicating each and every possible number along the continuum between about 1 and about 10. Thus, even if specific values within the range, or even points within the range, are explicitly identified or refer to only a few specific values, it is to be understood that the inventor appreciates and understands that any and all points or values within the range are to be considered to have been specified, and that the inventor is in possession of the entire range and all points within the range.
Coupled to the container body 12 along the length of the sidewalls 20, 22 are closure members 26. In the embodiment shown, a pair of closure members 26 is formed from a single, continuous flexible member that extends along either side of the container body 12 along the length of the sidewalls 20, 22 and across the bottom wall 24. In other embodiments, however, closure members may be formed from two or more separate members. Additionally, the closure members may be non-continuous segments, extending in portions along the length or a portion of the length of the sidewalls of the container body. The closure members 26 may be formed from a flexible material that may undergo plastic deformation so that it its shape is retained after being deformed. Such materials may be thin metal wire or tape. The thickness of the material for the closure member 26 may vary depending upon the material used for the container body 12. Thicker or more substantial materials may be used with container bodies that have a greater weight or resistance to being deformed so that the closure members 26 are adequate to facilitate closing and maintaining the flexible container in a closed configuration.
It has been found that circular or oval cross-sectional shapes are more suitable for metal closure members, with circular being particular well suited for metal closure members. Metal closure members may have a generally uniform and continuous cross-sectional area along generally its entire length, although tapered closure members or closure members with variations in cross-sectional areas may also be used.

In an alternate embodiment, the flexible container may have openings at opposite ends. Each end may be selectively closed or opened by twisting together or untwisting the closure members at a position adjacent to the openings. In this way, materials may be positioned within or removed from different ends of the flexible container.
While the invention has been shown in only some of its forms, it should be apparent to those skilled in the art that it is not so limited, but is susceptible to various changes and modifications without departing from the scope of the invention. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
