Abstract
A resealable flexible nonporous bag includes inner and outer film pockets having tops that are open or separable. The bag includes a plurality of malleable fibers, some of the fibers being sandwiched between first faces of the inner and outer film pockets and some fibers being sandwiched between second faces of the inner and outer film pockets. There is a first fold line in the inner and outer film pocket first faces, the malleable fibers being weakened adjacent the first fold line so as to predispose the inner and outer film pockets to fold along the first fold line. A second fold line is in the inner and outer film pocket second faces, the malleable fibers being weakened in the second fold line to predispose the inner and outer film pockets to fold along the second fold line.
Description
- The present invention relates generally to food containers and, more particularly, to a resealable nonporous bag for selectively maintaining the freshness of food products within the bag.
- The large and growing snack food market depends on having appropriate packaging to keep the food products fresh. Flexible nonporous packaging, such as film packaging, is advantageous in that it is virtually impermeable by air or moisture and is inexpensive to manufacture. However, flexible nonporous packaging is not typically resealable once it is initially opened and, as a result, the food products packaged therein tend to become stale and unappetizing.
- Various devices and methods have been proposed for maintaining a flexible nonporous bag in a closed configuration after it has been initially or subsequently opened. Namely, the open end of the package may be rolled up or twisted into a closed configuration. While this method may hold the bag closed for a period of time, the bag opening will naturally move toward the open configuration unless it is specifically held closed by tape, a clip, or other fastener. Although assumably effective for their intended purposes, the existing devices include fasteners that may become lost, adhesive or metal sealing tape that increase manufacturing costs, or a malleable member that may be repeatedly twisted and untwisted.
- Therefore, it would be desirable to have a resealable nonporous film bag that will hold its shape when rolled or twisted by a user. Further, it would be desirable to have a resealable nonporous bag having a multitude of semi-rigid fibers sandwiched between two
- Docket 7492 layers of film. In addition, it would be desirable to have a resealable nonporous bag that may be sealed and unsealed many times without degradation.
- Therefore, a resealable flexible nonporous bag according to the present invention includes inner and outer film pockets having tops that are open or separable. The bag includes a plurality of malleable fibers, some of the fibers being sandwiched between first faces of the inner and outer film pockets and some fibers being sandwiched between second faces of the inner and outer film pockets. There is a first fold line in the inner and outer film pocket first faces, the malleable fibers being weakened adjacent the first fold line so as to predispose the inner and outer film pockets to fold along the first fold line. A second fold line is in the inner and outer film pocket second faces, the malleable fibers being weakened in the second fold line to predispose the inner and outer film pockets to fold along the second fold line.
- Therefore, a general object of this invention is to provide a resealable film bag that will hold its shape when bent, folded, or twisted.
- Another object of this invention is to provide a resealable film bag having a multitude of semi-rigid fibers sandwiched between two layers of film.
- Still another object of this invention is to provide a resealable film bag that is easy to use and economical to manufacture.
- Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

FIG. 5 is a fragmentary view of a resealable bag according to another embodiment of the present invention. - A resealable flexible nonporous bag will now be described in detail with reference to
FIG. 1 a throughFIG. 5 of the accompanying drawings. More particularly, a resealable flexiblenonporous bag 100 includes inner andouter film pockets 110, 120 (FIG. 1 b). It is understood that reference to “film” in the specification and claims is meant to include flexible nonporous materials such as film, transparent or translucent plastic, film covered paper, and the like, such as is typically used in potato chip, snack (e.g. pretzels), and cereal packaging. While the present invention may be best understood for use with foil packaging, it should be appreciated that many forms of flexible nonporous materials may be used. - As shown in
FIG. 1 b, theinner film pocket 110 has atop 112 a that is open or separable, a bottom 112 b, opposedsides 114, and first and second opposedfaces 116 a, 116 b. Similarly, theouter film pocket 120 has atop 122 a that is open or separable, a bottom 122 b, opposedsides 124, and first and second opposedfaces 126 a, 126 b. - A plurality of
malleable fibers 130 are sandwiched between theinner film pocket 110 and theouter film pocket 120. For example, as shown inFIG. 2 c, themalleable fibers 130 may be sandwiched between thefirst face 116 a of theinner film pocket 110 and thefirst face 126 a of theouter film pocket 120. Similarly,malleable fibers 130 may be sandwiched between the second face 116 b of theinner film pocket 110 and the second face 126 b of the outer film pocket 120 (FIG. 1 b). At least some of themalleable fibers 130 are bendable to reclose the innerfilm pocket top 112 a and the outerfilm pocket top 122 a after thetops outer pockets 110, 120 (and themalleable fibers 130 therebetween) may be rolled or bent to close thetops malleable fibers 130 may keep thetops malleable fibers 130 may include metal, plastic, and/or composite materials, and may be based on performance, cost, bonding, and/or other considerations. - As shown in
FIG. 5 , theouter film pocket 120 includes at least onefold line 125. Afirst fold line 125 a may be in the inner film pocketfirst face 116 a and the outer film pocket firstface 126 a, for example, and a second fold line 125 b may be in the inner film pocket second face 116 b and the outer film pocket second face 126 b. Except adjacent the fold line(s) 125, themalleable fibers 130 may be generally uniformly configured between the inner andouter film pockets malleable fibers 130 are possible and likely acceptable, themalleable fibers 130 may extend generally parallel to theopposed sides 124 of theouter film pocket 120, and themalleable fibers 130 may be generally equally spaced (FIG. 1 b). At the fold line(s) 125, themalleable fibers 130 may be absent or weakened to dispose inner andouter film pockets second fold lines 125 a, 125 b). - The fold line(s) 125 (e.g., the first and
second fold lines 125 a, 125 b) may be generally parallel to or curved away from the outer film pocket bottom 122 b (FIG. 3 a), and may be relatively closer to the outer film pocket bottom 122 b than to the outerfilm pocket top 122 a (FIG. 5 ). Ifmalleable fibers 130 are between thefirst faces 116 a, 116 b and between thesecond faces 126 a, 126 b (FIGS. 1 b and 5), at least some of themalleable fibers 130 between thefirst faces 116 a, 116 b may be coupled to or unitary with at least some of themalleable fibers 130 between thesecond faces 126 a, 126 b (e.g., at points 119). - In use, contents may be placed in the
inner film pocket 110 in a conventional manner, and thetops tops FIGS. 1 a, 4 b, 4 d, and 5), the inner andouter pockets 110, 120 (and themalleable fibers 130 therebetween) may be rolled or bent to close thetops malleable fibers 130 may keep thetops outer pockets malleable fibers 130 may allow the inner andouter pockets FIG. 4 d, the inner andouter film pockets FIG. 4 b shows inner andouter film pockets fold lines 125. In addition, the fold line(s) 125 may make the inner andouter film pockets 110, 120 (and the malleable fibers 130) easier to bend than if afold line 125 was not present. - It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
