Description

FIELD AND HISTORICAL BACKGROUND OF THE INVENTION

The present invention is directed to gift sacks, and more particularly to a gift sack with a drawstring or the like and a method for making the same.

The aspect of wrapping articles in various types of decorative paper or the like material is no more visible than in the well-rooted custom of exchanging gifts. The industry's response to this custom has been to provide cardboard boxes in which the articles are placed and decorative paper is then wrapped and taped around the box. In order to attain this objective, boxes of varying dimensions are provided for accommodating articles of different sizes.

The conventional gift wrapping technique, however, is time-consuming, cumbersome and requires stocking a large number of boxes separate and independent from the stock of various decorative wrapping paper. In addition, it has been observed that conventional method of gift wrapping requires some training and expertise in terms of cutting the wrapping paper to size the dimensions of a given box without wastage, and then following a specific folding sequence in order to obtain a neatly and attractively wrapped package. Notwithstanding the training, it has been noted that the present technique requires a substantially long period of time in order to gift-wrap an article.

Examples of various gift sacks, receptacles and accessories, and methods for making same are disclosed in U.S. Pat. Nos. 207,933; 291,447; 293,353; 414,679; 1,605,481; 2,376,256; 2,710,639; 2,771,010; 2,799,611; 2,841,905; 3,132,794; 3,301,387; 3,568,918; 3,632,464; 3,637,455; 3,772,968; 3,913,648; 4,112,551; 4,270,247; 4,276,031; 4,329,382; 4,445,230; 4,476,168; 4,515,837; 4,558,463; 4,608,283; 4,721,502; 4,824,425; 4,832,677; 4,850,944; Des. 156,059; Des. 296,870; Des. 309,257; and, Glitterwrap and Duro Catalogs.

In view of the drawbacks associated with conventional technique, there is a need in the art for a gift sack article which is easy to use, inexpensive to manufacture and saves time.

OBJECTS AND SUMMARY OF THE INVENTION

The principal object of the present invention is to provide a gift sack with a drawstring or the like which is easy to use, inexpensive to manufacture and does not require specialized training for wrapping various articles.

DETAILED DESCRIPTION OF THE INVENTION

As illustrated in FIG. 1, gift sack G includes a top portion 10 with opening 12 and a closed bottom portion 14. The sack G may be made of any suitable material that has a backing layer 16 made of a conventional material, such as foil, paper, plastic or the like, and has a heat-sealable resin-coating 18 applied thereto on one surface thereof (see FIG. 10). The coating 18 is made of any suitable thermoplastic polymeric/resin material, and functions as an adhesive to bond two portions of the bag, as described below in detail. The backing 16 may have surface color or decoration applied thereto on the side opposite to resin-coating (18) side. The top portion 10 includes a drawstring or drawtape 20 or the like member which when pulled in the direction of arrows A, shown in FIG. 1, closes opening 12 by gathering top portion 10.

As shown in FIG. 2-3, the method of making gift sack G of the present invention includes first securing drawstring 20 to a bag forming panel 22 of a suitable material as described above. The panel 22 is of a dimension that would produce a sack of a predetermined size. The panel 22 is then spread flat on a support surface (not shown) with the resin-coating side 24 facing up and print side 26 facing the support surface (print omitted from FIGS. 3, 5-9 for clarity). The drawstring or drawtape 20 of a suitable width, preferably one inch, is then placed across panel 22 on side 24 such that drawstring ends 28 and 30 extend past side edges 32 and 34 of panel 22, respectively. It is preferable that drawstring ends 28 and 30 each extend past side edges 32 and 34 by at least five inches. The drawstring 20, it should be noted, is positioned so as to be parallel to top edge 36 of panel 22. The portion 38 of panel 22 that lies adjacent edge 36 and on one side of fold line 42 is then folded over inwardly about fold line 42, as indicated by arrows B in FIG. 2, so as to overlie drawstring 20 and lower portion 40. In this manner, the resin-coating side 25 of upper portion 38 directly faces resin-coating side 24 of lower portion 40.

The drawstring 20 is made of nylon or a suitable heat-treatable resinous material. It should be noted, however, that although drawstring 20 is made of a heat-treatable material, it is non-bondable with resin-coating 18.

As shown in FIGS. 3 and 11, heat is then applied across and over drawstring 20 by using conventional means (not shown), in order to seal simultaneously sections 39 and 41 of upper portion 38 with corresponding underlying sections 43 and 45 of lower portion 40, lying adjacent the sides of drawstring 20 thereby providing seal or bonding strips 44 and 46 (FIG. 3). The top edge portion 36 may then also be sealed to provide top seal or bonding strip 48. The sections 47 and 49 of upper and lower portions 38 and 40, respectively, lying between seal strips 44 and 48, therefore, remain unbonded (see FIG. 11). Unbonded section 47 defines a ruffle-forming portion which forms a ruffle when drawstring 20 is pulled to close opening 12 by gathering top portion 10.

The heat-sealing step is preferably carried out by passing a hot-roller 50 across the entire upper portion 38 such that the entire upper and lower portions 38 and 40 are sealed together simultaneously, as shown in FIGS. 5 and 12, thereby forming upper and lower seal or bonding strips 51 and 55, respectively. The upper strip or ruffle forming portion 51 is considerably wider than lower strip 55. Accordingly, when drawstring 20 is pulled to close bag opening 12, upper wider strip 51 forms an attractive ruffle. Preferably, the width of strip 51 is about two to four inches.

It should be noted, however, that since drawstring 20 is made of a material that does not bond with resin-coating 18, the sections 52 and 53 of upper and lower portions 38 and 40, respectively, that over and underlie drawstring 20, do not bond together and drawstring 20 remains free to slide therebetween, shown in FIGS. 11 and 12. The panel 22 is then folded in half about vertically extending fold line 54 such that right side edge 34 thereof overlies left side edge 2, and are sealed together to form seal or bonding strip 56, shown in FIG. 4. The bottom edge portion 58 of panel 22 is likewise sealed to form bottom seal or bonding strip 60.

As shown in FIGS. 2 and 3, a side strip 61 bound by edges 62, 63, 65 and 67, preferably one-half inch in width, is cut-out from upper portion 38 of panel 22 before heat-sealing upper and lower portions 38 and 40. This leaves a corresponding underlying strip 64 of lower portion 40 unsealed when heat is applied over drawstring 20 to bond portion 38 and 40 together. Therefore, when panel 22 is folded in half, the resin-coating 18 on strip 64 comes into contact with corresponding portion 66 of upper portion 38 lying adjacent side edge 32 of panel 22, and is sealed therewith when heat is applied.

Subsequently, a base 68, preferably made of a cardboard material and square in dimension, is placed inside the sack thus formed for creating a gift sack with a defined bottom, shown in FIG. 6. The bottom end portions 70 and 72 are subsequently folded underneath base 68 and sealed together in the conventional manner by placing a self-adhesive sticker 74 or the like.

FIGS. 8 and 9 illustrate an alternative method of making the gift sack G of the invention. In particular, the fold-over upper portion 38 shown in FIG. 2, is substituted by a separate panel 76 that is positioned over drawstring 77 having been earlier placed on bag-forming panel 78. Both panels 76 and 78 are made of a like material that has a backing layer with a resin-coating on one side thereof. The panel 76 is placed such that the resin-coating side 80 thereof faces the resin-coating side 82 of panel 78, and the two panels are heat sealed in the manner described above.

FIG. 9 discloses an embodiment of gift sack G shown in FIG. 8, where the top edges of over-panel 76 and bag forming panel 78 have scalloped edges 84 and 86, respectively. This arrangement produces a bag with a scalloped edge opening. It should be noted that over-panel 76 would be disposed on the inside perimeter of bag opening 12, when the gift sack has been sealed and fully assembled. Therefore, it may be desirable to omit any printing or color from the side 88 of panel 76 which lies opposite to the resin-coating side 80 thereof.

Preferably, side 88 of over-panel 76 is silver colored with no printing and side 80 thereof includes decorative printing thereon. Likewise, side 82 of bag-forming panel 78 is silver colored with no printing, and side 90 thereof includes printing thereon.

While it is not necessary to apply a chemical (lubricating) or release agent to drawstring 20 or 77 to prevent its bonding with the resin-coating on the bag forming material, it may be desirable in certain circumstances to do the same. More specifically, talc, talcum powder, or the like material can be sprayed onto the sections of bag-forming panels 22 or 78 that over and underlie drawstring 20 or 77 so that when heat is applied, the drawstring 20 or 77 remains unbonded to the bag-forming material.

For example, in the embodiment disclosed in FIG. 13, a lubricant 96 has been applied on sections 92 and 94 of facing surfaces 18 of each of upper and lower portions 38 and 40, respectively, prior to positioning drawstring 20.

It should be noted that it is not necessary that both over-panel 76 and bag-forming panel 78 include a resin-coating applied on one side thereto. In other words, it is sufficient that either the side 80 of panel 76 facing panel 78, or the side 82 of panel 78 facing panel 76 has the resin-coating such that when heat is applied, panels 76 and 78 are sealed together.

In use, a user simply needs to place an article inside the gift sack G through top opening 12 and pull drawstring ends 28 and 30, as shown by arrows A in FIG. 1. The pulling forces cause drawstring 20 to constrict top opening 12 and gather top portion 10 in the known manner. The drawstring ends 28 and 30 can then be tied together to form a bow for making a decorative package. FIG. 14 shows a top portion of gift sack G after the drawstring has been pulled in direction A and the bow has been tied in the known manner, seal strip 48, unbonded section 47, seal strip 44, drawstring 20, and seal strip 46 being shown in hidden line.

While this invention has been described as having preferred designs, it is understood that it is capable of further modifications, uses, and/or adaptations of the invention, and including such departures from the present disclosure as come within known or customary practice in the art to which the present invention pertains, and as may be applied to essential features hereinbefore set forth, and fall within the scope of the invention or the limits of the claims appended hereto.
