Abstract
A method for sealing a bag which is formed from a tube of material and has front and rear sides, a pair of opposing, inward-tending gusset folds, each of these folds having front and rear vertical creases, comprising the steps of slitting each of the opposing front creases along longitudinal their axes, obtaining front and rear plies. A first rearward fold is formed by rearwardly folding the rear plies together with the rear vertical creases such that the inner surface of the rear ply is visible. A second rearward fold is formed by rearwardly folding the first fold until the inner surface of the rear ply lays against the rear side of the bag.
Description
- Embodiments are disclosed herein with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
-
FIG. 1A is a perspective view of the rear of a bag; -
FIG. 1B is a perspective view of the front of a bag; -
FIG. 2 is an elevational view of one lateral side of the bag showing a slit in one crease; -
FIG. 3 is an elevational view of the lateral side of the bag showing the portions to be folded grouped together; -
FIG. 4 is an elevational view of the lateral side of the bag after a first rearward fold; -
FIG. 5 is an elevational view of the lateral side of the bag after a second rearward fold; -
FIG. 6 is an elevational view of the rear side of the bag after the first rearward fold; and -
FIG. 7 is an elevational view of the rear side of the bag after the second rearward fold. - The various embodiments of the present invention and their advantages are best understood by referring to
FIGS. 1 through 7 of the drawings. The elements of the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the invention. Throughout the drawings, like numerals are used for like and corresponding parts of the various drawings. - The drawings represent and illustrate examples of the various embodiments of the invention, and not a limitation thereof. It will be apparent to those skilled in the art that various modifications and variations can be made in the present inventions without departing from the scope and spirit of the invention as described herein. For instance, features illustrated or described as part of one embodiment can be included in another embodiment to yield a still further embodiment. Moreover, variations in selection of materials and/or characteristics may be practiced to satisfy particular desired user criteria. Thus, it is intended that the present invention covers such modifications as come within the scope of the features and their equivalents.
- Furthermore, any reference in the specification to “an embodiment,” “one embodiment,” “various embodiments,” or any variant thereof means that a particular feature or aspect of the invention described in conjunction with the particular embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases “in one embodiment,” “in another embodiment,” or variations thereof in various places throughout the specification are not necessarily all referring to its respective embodiment.
- Shown in FIGS. 1A,B is a bag A of the type often used for animal feed, or similar types of contents. Bag A is made from a durable, flexible material suitable for such containment and storage of such material. One non-limiting example of such a material is polypropylene, and further, woven polypropylene. Other examples include polyethylene and blends of polypropylene and polyethylene, paper to polypropylene or paper. Bag A is formed from a tube-like structure which is cut to size. Then one end is closed and sealed, the bag is filled, and the opposing end is then sealed. For orientational reference, bag A includes a
front side 11, and an opposingrear side 12. Thefront side 11 may be considered the side on which prominent displays of labeling comprising, for example, graphic designs, trademarks, and the like, a notional example of which is represented inFIG. 1B . For storage purposes when the bag is empty, bag A is collapsible, having a pair of opposing inwardly-projecting gusset-type folds 1 formed at the lateral sides 15, 16 of the bag.FIG. 2 illustrates an end portion of an unclosed bag A, viewed from the perspective of agusset fold 1, where twoouter creases gusset fold 1 are referenced. - A
slit 5 is made in anouter crease 4, preferably the outer crease adjacent the side of bag A that will be the front of thebag 11. Theslit 5 then creates aforward ply 6 and arear ply 7. Theforward ply 6 is kept in place while a first rearward fold (FIG. 4 ) is formed by folding therear ply 7 along with therear fold 3. The first rearward fold is creased roughly at thevertex 5 a ofslit 5. A second rearward fold (FIG. 5 ) is created by fold the entire bag A rearward where it is creased approximately at or above the level reached by the ends of the plies 14 (indicated by ghosted line) after the first rearward fold. - Referring to
FIGS. 6 and 7 , means for securing the fold is illustrated inFIG. 6 where after the first rearward fold, adhesive 9 is deposited on the inner surface ofrearward ply 7. Adhesive 9 may be any suitable adhesive for securing or bonding the material to itself. By way of non-limiting example, adhesive 9 could be a hot melt adhesive known to those skilled in the relevant arts. In another embodiment,adhesive 9 is also deposited upon the rear surface of the bag A within the area at which the inner surface ofply 7 contacts it. -
FIG. 7 depicts the completed folded closure. Inner surface of rearward ply 7 (represented by dashed line) is bonded torear surface 12 of bagA. Front ply 6 extends roughly vertically with respect to the bag, beyond the crease of the first rearward fold.FIG. 1B , then, shows an exemplary bag A from the front perspective where it is apparent that an observer cannot see any seams, seals, or closures, thus presenting a more aesthetically pleasing package to the customer. - As described above and shown in the associated drawings, the present invention comprises a method for closing and sealing a tube-formed bag and bags produced thereby. While particular embodiments of the invention have been described, it will be understood, however, that the invention is not limited thereto, since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings. It is, therefore, contemplated by the following claims to cover any such modifications that incorporate those features or those improvements that embody the spirit and scope of the present invention.
