Description

FIELD OF THE INVENTION

The present invention relates to self opening square bags with handles, and in particular, to bag closures for covering the open tops of such bags.

BACKGROUND

Self opening square (SOS) bags are commonly used throughout the world for a number of purposes, including uses as gift bags and shopping bags. The term SOS is an industry recognized term, but SOS bags are not necessarily square as the name suggests. Rather, most are rectangular in shape and come in many sizes, colors, and patterns. Typical SOS bags are shown in FIGS. 1A and 1B and 2A and 2B. Each includes an open top, a pair of handles disposed either outside the bag, as in FIGS. 1A and 1B, or inside the bag as in FIGS. 2A and 2B, and each folds substantially flat when not in use, as shown in FIGS. 1B and 2B. The SOS bags shown in FIGS. 1A and 1B and 2A and 2B are often referred to as “euro-style” shopping bags, which are commonly considered quality shopping bags, incorporating a reinforced turn-top, a bottom board, and better quality handles attached by knots, a continuously connected loop, or integrally to the turn-top by insertion through slits or die-cuts and attachment to the turn-top reinforcement. Such bags may use other manners of handle construction from whatever material, including but not exclusively woven, braided or twisted natural or synthetic fibers, ribbons or tapes of whatever made, plastic handles, plastic molded handles, or handles made by any other process or from whatever other materials.

When used as gift bags, the open top of the SOS bag must be obscured by tissue paper or some other barrier to prevent the recipient for knowing what it inside. Similarly, when used as shopping bags, paper or other barriers must be placed over items, such as clothing made from silk or suede, to protect the items from damage from moisture entering through the open top of the bag. The use of tissue paper or other barriers in each case is not aesthetically pleasing and, as most papers used for these purposes do not repel moisture, they do not adequately protect the items inside of the bag from damage or theft. Therefore, there is a need for a bag closure for the open tops of SOS bags that will be aesthetically pleasing and will effectively protect the contents of the bag from damage or theft.

A number of prior art bags and bag closures have been developed, but each has major disadvantages. For example, U.S. Pat. No. 6,000,849 discloses a gift package that includes a bag topper that is designed to fit within the open top of the bag. This invention is more aesthetically pleasing than paper. However, its major drawback is its lack of a means or securing it to the open top of the bag, which makes it prone to shifting during transit. Accordingly, it is not effective at protecting the contents of the bag from damage.

U.S. Pat. No. 6,146,018, discloses a gift package with a topper that includes a pair of paperclip-like extensions that attach the topper to the right and left side gussets of the bag. This topper also has significant drawbacks. First, it requires the topper to rest above the top of the bag, which results either in the topper extending past the periphery of the bag or not adequately covering the top. In either case, it is not aesthetically pleasing, does not adequately obscure the contents when used as a gift bag, and does not adequately protect the contents of the bag. Further, it is prone to becoming dislodged in transit, which renders it ineffective at protecting the contents of the bag from damage.

U.S. Pat. No. 6,012,842, discloses a bag that represents an attempt to make a folding carton box from a bag and includes an integrated lid that purportedly folds flat when not in use. Unfortunately, this bag also has significant drawbacks. Because the lid is integrated with the bag, both the lid and bag must be made from the same material. Depending on the material chosen, the material is either heavy and rigid enough to make a folding carton, for example 350 gsm or more, or it's light enough to make a shopping bag, generally 120-170 gsm. However, it cannot be both. Accordingly, if the heavier material is chosen, the bag will not fold easily and the entire package will constitute a box and not a shopping bag that can be easily carried. If the lighter material is chosen, the lid will not be rigid enough to prevent deformation, which renders it ineffective at protecting the contents of the bag from damage.

U.S. Patent Publ. No. 2012/0051669 discloses a topper that takes the form of a decorative pop-up similar to those pages in children's books that pop up when opened. Certain embodiment of this topper function in the same manner as U.S. Pat. No. 6,000,849 and have the same drawbacks. Others are secured to the interior of the bag by adhesive material making them unsuited for reuse. Still others extend over the top of the bag and are secured to the front panel and back panel by adhesive, again making them unsuitable for reuse. All embodiments disclosed in the publication overlook that fact that they seek to marry a flexible structure, the bag, to a rigid or semi-rigid one. They only work by modifying one or the other materials and this causes function to fail.

Therefore, there is a need for a bag closure for the open tops of handled SOS bags that will be aesthetically pleasing, will effectively protect the contents of the bag from damage or theft, is secured within the open top of the bag, is not prone to shifting and loss of protection in transit, may be easily folded flat when not in use, is economical to manufacture, and which allows the bag to be reused.

SUMMARY OF THE INVENTION

The present invention is an internal bag closure, and a bag kit that includes an SOS bag and the internal bag closure of the present invention.

The internal bag closure of the present invention is manufactured from a single sheet or panel of paper or lightweight board. The paper weight of the internal bag closure would ordinarily be between 250-400 gsm, but might be more or less, circumstances requiring. The internal bag closure would ordinarily be made of paper or board, laminated or unlaminated, coated or uncoated, or any other suitable material that offers a similar function.

A bag is ordinarily measured first by its width left to right, then by the open dimension of its side gussets, and finally by its height, such that a bag 405+150×450 mm measures 405 mm wide, has a depth, equal to its open gusset dimension, of 150 mm, and a height of 450 mm. The internal bag closure preferably has a length that is generally but not exclusively 10-15% less than the width of the bag. This is preferred in order to fit the internal bag closure within the side gussets without the gussets pressing against the ends of the internal bag closure. The preferred panel has two parallel folded over sections, which extend the length of the internal bag closure and are generally and approximately 20-30 mm in width. The folds in the parallel folded over sections define a central section having a width approximately equal to the depth of the bag. Each of the parallel folded over sections of the panel include a handle orifice therethrough. The handle orifice is shaped to allow the easy passage of the bag's handles through the orifice and their subsequent locking within the orifice when the handles are drawn to their natural handle attachment points on the bag.

The preferred internal bag closure incorporates a scalloped portion at each end of its central section, which is the section that covers the bag opening. Such scalloped portion is preferably die-cut and defines an arc that is geometrically calculated to fit within the interior of the bag based upon the bag width and depth to allow the natural inward tendency of the gusset fold to be unimpeded.

In the preferred internal bag closure, the parallel folded over sections are of a double thickness formed by including two sections of equal width defined by a fold, identically shaped handle orifices through each section, and folding over the sections upon themselves and glued together. This arrangement is preferred as it increases the durability of the internal bag closure, and it provides a finished edge to the internal bag closure. However, other embodiments are of single thickness.

In embodiments of the internal bag closure for use with knotted cord or ribbon handled bags, the handle orifice includes an expanded center portion sized to allow the knots at the ends of a cord or ribbon handle to pass therethrough. The expanded center opening preferably an oblong oval shape, but can also be rectangular, circular, or any other shape that allows the knots at the ends of the handle to pass therethrough. Slots of a reduced width having a size less than the diameter of the cord, referred to herein as its thickness, or the thickness of the ribbon extend from either side of the expanded center portion along the length of the handle orifice and terminate such that the end of each slot is disposed proximate to the location of the handle openings through the bag. The width of each slot is designed to be less than the less than the thickness of the cord or ribbon in order to provide a frictional lock that retards movement of the cord or ribbon within each slot. The slots preferably terminate in a semicircle, which is preferred due to its improved tear resistance over sharply angled ends. However, in some embodiments for use with cord handles, the slot terminates in a round opening having a diameter slightly smaller than the diameter of the cord.

In embodiments of the internal bag closure for use with non-knotted ribbon handled bags, the handle orifice includes an expanded center portion sized to allow the ribbon handle to pass therethrough. Slots of a greatly reduced width, having a size less than the thickness of the ribbon, extend from either side of the expanded center portion along the length of the handle orifice and terminate such that the end of each slot is disposed proximate to the location of the handle openings through the bag.

In all embodiments of the internal bag closure, the handle is disposed through the expanded center portion of each orifice and each side of the handle is moved outward along the slots until it reaches the slot termination, where they are held in place.

The kit of the present invention includes an internal bag closure and a conventional SOS bag. The kit is preferably provided partially assembled with the internal bag closure attached to the internal front face of the bag, and flat against this face. The user would readily deduce the attachment to the second side from that seen on the first, a maneuver ordinarily requiring no more than one to two seconds.

The internal bag closure is easily re-closable such that the user may open the shopping bag and re-close it multiple times, maintaining the practicality offered by a shopping bag, that its contents may be removed or added to as required.

As is readily evident from the foregoing, a closure for SOS shopping bags with or without turn-tops, reinforced or not, has long been sought and a variety of impractical, impracticable, unaesthetic, or uneconomic attempts have been made to find a solution. The present invention overcomes the drawbacks of the prior attempts by incorporating the following:

(a) Practicality: Its use is intuitive. It folds flat with the bag upon manufacture, for delivery and for storage. It protects the contents of the bag from ambient conditions, dust and weather. It shields the contents from view thus diminishing the attraction of theft and also impedes theft. It not only shields the contents from view but also allows a decorative and more gift-like presentation. It can be used for the furtherance of brand identity or other advertising.

(b) Aesthetic appeal: The bag closed by the internal bag closure will be at least as appealing as an open bag without the closure, and indeed more so.

(c) Economy: The cost of adding the closure to a “euro-style” shopping bag will not exceed 15% of the basic bag cost, enabling broad use, and even certain consequential economies, as the elimination for the need for tissue paper, often a poor substitute for a closure.

(d) Removability: The consumer who wishes to reuse the shopping bag, but without the closure, can easily and intuitively remove it.

Therefore it is an aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that will be aesthetically pleasing.

It is a further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that will effectively protect the contents of the bag from damage.

It is a further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that is secured within the open top of the bag.

It is a further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that is not prone to shifting and loss of protection in transit.

It is a further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that may be easily folded flat when not in use.

It is a further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that is economical to manufacture.

It is a still further aspect of the present invention to provide a bag closure for the open tops of handled SOS bags that allows the bag to be reused.

These aspects of the present invention are not meant to be exclusive and other features, aspects, and advantages of the present invention will be readily apparent to those of ordinary skill in the art when read in conjunction with the following description and accompanying drawings.

DETAILED DESCRIPTION

FIG. 3 shows a typical prior art SOS bag 10 open in a perspective view. Prior art SOS bag 10 includes a front panel 12, a back panel 14, right side gusset 16, left side gusset 18, bottom gusset 20, an open top opposite the bottom gusset 20, and a turntop 22 that extends around the periphery of the open top. Turntop 22 is an inward fold of sheet forming the front panel 12, back panel 14, right side gusset 16, and left side gusset 18, and is included to reinforce the open top of the SOS bag 10 to resist tearing. However, it is noted that not all SOS bags include a turntop 22.

Right side gusset 16 and left side gusset 18, and bottom gusset 20 allow the SOS bag 10 to be expanded from a flat folded position to the open position, as shown in FIGS. 1 and 3. When folded, bottom gusset 20 folds upward toward the formerly open top and right side gusset 16, left side gusset 18 fold inward. When expanded and open, prior art SOS bag 10 may rest upright with bottom gusset 20 on the ground forming the bottom of the bag 10. Although the SOS bag 10 of FIG. 3 includes an inverted bottom gusset 20 that folds upward between the front panel 12 and back panels 14 when closed, it is noted that many prior art SOS bags 10, including the bag shown in FIG. 2A and 2B, include bottom gussets 20 that fold upward and cover part of the back panel 14 when folded.

As is typical of many SOS bags, the SOS bag 10 of FIG. 3 also includes a front handle 24 a back handle (not shown). The front handle 24 and back handle of the SOS bag 10 of FIG. 3 are cords that that pass through handle openings (not shown) through the front panel 12 and back panel 14 respectively and through turntop 22 and are secured by knots 26 that prevent the cords from passing back through the turntop 22. This type of SOS bag is referred to herein as a knotted external handle bag.

As shown in FIG. 2A, it is also common for the front handle 24 and back handle 28 to not extend through the front panel 12 and back panel 14 but, rather, to extend only through the turntop 22. In these bags, the handles 24, 28 are disposed between and secured to the turntop 22 and the front panel 12 and back panel 14 respectively, such that the ends of the handles 24, 28 are hidden from view and the handles 24, 28 extend inside of the SOS bag 10. This type of SOS bag is referred to herein as an internal handle bag.

It is also common for the front handle 24 and back handle 28 of SOS bags 10 to be made from ribbons instead of cord. Such ribbon handles may be used in knotted external handle bags or internal handle bags in a manner similar to those described above. Referring now to FIGS. 4A-6, one embodiment of the internal bag closure 50 and kit 100 including a knotted external handle bag 10 is shown and described. FIG. 4A is an assembly view of the kit 100 of the present invention. The kit 100 includes a bag 10 and an internal bag closure 50. The bag 10 is a knotted external handle bag that is similar in all respects to the bag 10 described with reference to FIG. 3.

The internal bag closure 50 is most clearly described with reference to FIG. 6. The internal bag closure 50 is preferably manufactured from a single sheet or panel of paper or lightweight board. The paper weight of the internal bag closure 50 is preferably between 250-400 gsm, but may be more or less depending upon the particular application, and may be laminated or unlaminated, coated or uncoated, or made of any other suitable material that offers a similar function.

The internal bag closure 50 has a length that is preferably 10-15% less than the width of the bag. The internal bag closure 50 incorporates a right end 70 and left end 72 of its central section 56, which is the section that covers the open top of the bag. The ends 70, 72 are preferably die cut scalloped shaped ends 70, 72 that each define an arc that is geometrically calculated based upon the bag width and depth to allow the natural inward tendency of the folds of the side gussets 16, 18 to be unimpeded.

The preferred internal bag closure 50 has front folded over section 52 and back folded over section 54 which are substantially parallel, extend the length of the internal bag closure 50. Front fold 53 and back fold 55 in the panel at the interior of the in the parallel folded over sections 52, 54 define a central section 56 having a width approximately equal to the depth of the bag 10. The distance between front edge 71 and front fold 53 and rear edge 73 and rear fold 55 are each preferably approximately 20-30 mm. Each of the parallel folded over sections 52, 54 of the internal bag closure 50 includes a handle orifice 58, 60 therethrough. Each handle orifice 58, 60 is shaped to allow the easy passage of the handles 24, 28 of the bag 10 through the orifice 58, 60 and their subsequent locking within the orifice 58, 60 when the handles are drawn to their natural handle attachment points on the bag 10.

In the embodiment of the internal bag closure 50 shown in FIG. 6, which is adapted for use with cord handled bags or knotted ribbon handle bags, each handle orifice 58, 60 includes an expanded center portion 62 sized to allow the cord handle 24, 28, or knots 26 of a cord or ribbon handle, to pass therethrough. Slots 64, 65 of a reduced width having a size less than the thickness of the handles 24, 28 or the knots 26 extend from either side of the expanded center portion 62 along the length of each handle orifice 58, 60 and terminate such that the end 66, 67 of each slot is disposed proximate to the location of the handle openings through the bag 10. In the embodiment of FIG. 6, the end 66, 67 of each slot 64, 65 is semicircular in shape. This shape is preferred due to its improved tear resistance over sharply angled ends. However, the end 66, 67 of each slot 64, 65 may take any shape.

Referring again to FIGS. 4A-4D, the assembly of the kit 100 is described. As shown in FIG. 4A, the internal bag closure 50 is first positioned above the open top of the bag 10. As shown in FIGS. 4B and 4C, the internal bag closure 50 is then fitted into the open top of the bag 10 and the knots 26 of handle 26 are passed through the expanded center portion 62 of orifice 60. The knots 26 are then moved outward through slots 64, 65, as indicated by the arrows in FIG. 4B, until the knots 26 reach the ends 66, 67 of each slot 64, 65, as shown in FIG. 4C. The knots 26 of the other handle 24 are passed through the orifice 58 as also shown in FIG. 4C and process is then repeated. The end result of this process is shown in FIG. 4D.

One distinct advantage of the internal bag closure 50 is its ability to be secured and stored flat within the bag 10 when not in use. As shown in FIG. 5, when the bag 10 is emptied and is ready for storage, the knots 26 of one handle 29 are removed from the orifice 60 while the other knots 26 remain in their location at the ends 66, 67 of each slot 64, 65 in orifice 58. This results in the internal bag closure 50 hanging parallel to one side of the bag 10, allowing the bag 10 to be folded flat with the internal bag closure 50 secured within.

Referring now to FIGS. 7A-7C, a preferred embodiment of the internal bag closure 50 and kit 100 including a internal cord handle bag 10 is shown and described. FIG. 7A shows the bag closure 50 in a stored position within the bag 10 with the handle 24 in its assembled location with ends of the handle 24 at the ends 66, 67 of each slot 64, 65 in orifice 58. As was the case with knotted external handle bag, the ends 66, 67 of each slot 64, 65 align with the location of the handle openings (not shown) in each side of the bag. As shown in FIG. 7B, the internal bag closure 50 is assembled by moving it into position within the open top of the bag 10 and passing the handle 28 through the expanded center portion 62 of the orifice 60. The handle 28 is then drawn outward through slots 64, 65 until the two ends of the handle 24 reach the ends 66, 67 of each slot 64, 65, as shown in FIG. 7C.

Referring now to FIG. 8, another embodiment of the internal bag closure 50 includes parallel folded over sections 52, 54 that are of a double thickness. As shown in FIG. 8, each of these double thickness portions 52, 54 are formed by including additional sections 90, 92 of equal width to the width of the folded over sections 52, 54, additional folds 94, 96, and identically shaped handle orifices 58A, 58B and 60A, 60B through each section 52, 54 and 90, 92, and folding over the sections along folds 94, 96. The end result of this process when performed on the sheet of FIG. 8 is the internal bag closure of FIG. 6. This arrangement is preferred as it increases the durability of the internal bag closure and provides the closure with finished edges. However, other embodiments are of single thickness.

In the embodiment of FIG. 8, the end 66, 67 of each slot 64, 65 includes a round opening having a diameter slightly smaller than the diameter of the cord handle 24, 28 but smaller than the knots 26. This design prevents impingement upon the handles 24, 28 that could cause damage to the handles 24, 28 and/or the slots 64, 55 of the internal bag closure. However, this embodiment does not allow the internal bag closure 50 to be held tightly within the bag and, therefore, is not preferred.

Referring now to FIG. 9, an embodiment of the internal bag closure 50 for use with non-knotted ribbon handles is shown. This internal bag closure 50 is similar in most respects to the internal bag closure 50 of FIG. 6, except for elimination of the scalloped ends and the difference in the slots 64, 65 in the orifice. In this embodiment, the handle orifice 58, 60 includes an expanded center portion 62 sized to allow the ribbon handles to pass through in a manner similar to the cord handle shown in FIGS. 7A-7C. Slots 64, 65 are of a vastly reduced width and essentially take the form of slits having a width less than the thickness of the ribbon from which the handles are formed. Slots 64, 65 extend from either side of the expanded center portion 62 along the length of each handle orifice 58, 60 and terminate such that the end 66, 67 of each slot is disposed proximate to the location of the handle openings through the bag 10. The ends 66, 67 of the slots 64, 65 these embodiments do not include round openings like those of FIG. 6 and, rather are merely extensions of the slots.

Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions would be readily apparent to those of ordinary skill in the art. Therefore, the spirit and scope of the description should not be limited to the description of the preferred versions contained herein.
