7 Claims. (Cl. 229-62) ABSTRACT OF THE DISCLOSURE A bag with the end folded down and sealed to itself along a band parallel to the fold; a handle being provided by finger holes in the bag and intersecting the band, the apertures being die cut across the band or fusion-formed with heat sealed peripheries.
This invention relates to a bag for confining articles for transport and, storage and having a carrying handle formed in the upper marginal portion thereof.
An object of my invention is to provide a new and improved article-confining bag with a novel and improved bag carrying portion formed integrally into the upper marginal edge portion of the bag.
Another object of my invention is to provide an improved article-confining bag with a simple and inexpensive closure formed in the upper marginal portion of the bag, into which a carrying feature is provided of a nature as to be formed by high speed processing machinery.
Another object of my invention is to provide in an article confining bag constructed of heat scalable material, a carrying handle which is easy on a persons fingers so that a substantial weight of material can readily be handled without injuring or unduly tiring a persons hand.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
FIG. 1 is a perspective view of a bag incorporating the present invention.
FIG. 2 is an enlarged detail section view taken at approximately 22 in FIG. 1.
FIG. 3 is an enlarged detail section view taken approximately at 33 in FIG. 1.
FIG. 4 is a perspective view of a modified form of the bag.
FIG. 5 is an enlarged detail elevation view of a portion of the bag illustrated in FIG. 4.
FIG. 6 is an enlarged detail section view taken approximately at 6-6 in FIG. 5.
FIG. 7 is a perspective view of another modification of the bag and incorporating the present invention.
FIG. 8 is an enlarged detail section view taken approximately at 88 in FIG. 7.
FIG. 9 is an enlarged detail section view, similar to FIG. 8, but illustrating a further modification of the bag incorporating my invention.
In FIG. 1, the bag 10 is constructed of a tube of flexible heat sealab-le material, such as polyethylene, which is flattened into an oblong bag shape so that the bag essentially has a pair of front and rear flattened panels 11 and 12 in confronting relation with each other. The bag is shown having a closed bottom 13, and as illustrated the bag 10 has a quantity Q of merchandise such as fertilizer contained therein. The bag 10 is particularly adapted for confining small quantities of various granular materials, such as fertilizer, or for confining articles of manufacturers which are commonly sold in retail stores, and the bag is well adapted to be carried by a purchaser from the store, substantially in the manner of a womans purse.
3,339,825 Patented Sept. 5, 1967 "ice As illustrated in FIGS. 2 and 3, the upper portion 14 of the bag is folded at 15 downwardly so as to define a multiple thickness closure area 16, cooperatively defining a strong handle and an efiicient closure for the bag 10. The closure area 16 is provided with a pair of continuous seals 17 and 18 in spaced and parallel bands extending entirely across the width of the bag. The seal 18 provides a complete closure for the interior of the bag and fuses together the multiple thicknesses of the closure area to very materially strengthen the bag in the closure area 16 which also serves as a handle.
The closure area 16 is also provided with a plurality of finger-receiving holes or apertures 19, the periphery of each intersecting the seal 17 so that the edges 20 of the multiple thicknesses in the closure area are held together by the seal 17.
In the form illustrated in FIGS. l-3, the holes 19 are die cut around their entire peripheries 19.
It will be noted that the holes 19 are spaced from each other so that the fingers of a persons hand can be comfortably inserted into these holes for gripping the bag. The sealing together at the edge 20 of the multiple thicknesses produces an intimate cooperation between the several thicknesses of heat scalable polyethylene as to provide a handle of very substantial strength and comfort for the fingers. The weight of the material in the bag and the tension applied at the holes 19 on the fingers is spread out over a substantial width of the bag by the seals 17 and 18, and furthermore, the upper peripheral portions of the holes 19 tend to turn over slightly under weight of the material Q so as to distribute the weight over a substantial surface area of the persons fingers.
The construction of the bag illustrated in FIGS. 4, 5, and 6 is substantially the same as that hereinbefore described. The flattened rear and front panels 31 and 32 have their upper portions 33 folded downwardly at 34 to define a multiple thickness closure portion 35 having seals 36 and 37 fusing together all of the thicknesses of polyethylene material in the closure portion 35. The holes or apertures 38 are die cut incompletely around the periphery 39 of the holes and in intersecting relation with the seal 36 so as to define a depending flap 40 attached to the closure area 16 at the top of each of the holes 38. The flap also has multiple thicknesses which are secured together by the seals 36' formed prior to the die cutting of the holes 38.
The several flaps 40 at each of the holes is swung out of the hole and folded upwardly as illustrated in FIG. 6 when a persons fingers are inserted into the apertures for carrying the bag. It will be understood that the seal 36 which is intersected by the die cut peripheries of the holes, holds the multiple thickness of the closure area together adjacent the holes 38 as to multiply the strength of the material by assuring all of the available material is continuously used in supporting the load carried by the bag.
Retaining of the multiple thicknesses together in the closure area 35 also facilitates easier insertion of the persons fingers through the holes.
Additionally, and of substantial importance in this form of the invention, the flaps 40 provide a smoothly rounded or contoured surface against which the fingers of a persons hand press when the bag 30 is lifted by means of the fingers extending the the holes.
In the form of the invention illustrated in FIG. 7, the bag is substantially identical to bag 10 hereinbefore de scribed, but it will be noted that the apertures 51 in the closure area 52 have diametrically opposite portions 53 of the hole peripheries secured together by the seal 54 which is entirely intersected by each of the holes 51. This contrast to the placement of the holes 19 in FIG. 1 which intersect the seal 17 only at the edges 20 adjacent the lower 3 portion of the periphery and the seal 17 is uninterrupted across the entire width of the bag.
The form of the bag 60 illustrated in FIG. 9 is similar to the bags 10 and 50 of FIGS. 1 and 7 and has the seals 61 and 62 in the closure area 63. Each of the apertures 64 is formed by melting the heat sealable material and forming an annular bead 65 at the entire periphery of the hole. The complete peripheral bead around the whole periphery provides additional strengthening by assuring complete cooperation between all of the thicknesses of the closure area 63 in supporting the material carried by the bag. The peripheral bead 65 also increases the comfort in supporting the bag on a persons fingers. It will be seen that I have provided a new and improved bag having an integrally formed carrying handle in such a simple and inexpensive manner as to eliminate the need for other form of carrying devices or handle structures or bags in which rather heavy products are sold. The bag provides a complete closure to confine the granular material or other type of merchandise therein.
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.
