Abstract:
Disclosed are small, compact devices that provide readily deployed storage for small personal items, and they can also readily be returned to their stowed configuration. This toggling between deployed and stowed can be accomplished without a required change to the connection of any such device to another object, such as a travel case. The devices provide specific benefit to people going through an airport or building security checkpoint at which it is a requirement that pocket items such as cell phones, keys, and coins must be removed from one&#39;s pockets for assessment by a scanning apparatus.

Description:
CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This application claims the benefit of U.S. provisional application Ser. No. 60/742,193, filed on Dec. 2, 2005, the entire content of which is hereby incorporated herein by reference. 
     
    
     FIELD OF INVENTION  
       [0002]     The invention relates to readily deployed and stowed storage devices for temporary holding and transporting of personal items, especially when a person and the person&#39;s personal property are being screened at a security checkpoint.  
       BACKGROUND OF THE INVENTION  
       [0003]     People often find themselves with too many things to carry at once. This is true for travelers using commercial transport who take with them carry-on luggage. It is also true for those who carry briefcases and rolling travel cases during their trips to and from work, as well as to business meetings or, for lawyers, to court appearances.  
         [0004]     When people are required to go through a security checkpoint at the airport, at a government building, or at certain commercial buildings, getting such travel cases and myriad metal pocket items processed at the checkpoint is time consuming, and it can sometimes lead to the pocket items being unintentionally left behind at the checkpoint.  
         [0005]     The invention of this application addresses these and related problems.  
         [0006]     The invention provides convenient, closable storage devices of adequate size to carry typical pocket items, such as keys, coins, cell phones, music playback devices, text-messaging devices, watches, and wallets, that need to scanned at security checkpoints.  
         [0007]     These storage devices are collapsible, and in their collapsed state they can be unobtrusively attached to a travel case. For example, certain embodiments of the invention can be attached and be left attached to a piece of luggage just as would a luggage ID tag. When in their collapsed state, these embodiments are generally comparable in size and weight to such an ID tag. Yet, they can be quickly deployed, used for temporary storage, and then collapsed again.  
         [0008]     For use at a security checkpoint, the devices are designed to be deployed, filled with pocket items, closed, and then sent through the security scanner along with the travel case. At the exit end of the scanner machine, the device and its contents can be readily retrieved with the travel case, and the items stored within the device may be removed and placed back in one&#39;s pockets there or at some later time and place of convenience.  
         [0009]     Storage devices are known which attach to travel cases in order to carry additional items, even while such cases are sent through a scanner machine, yet those devices lack certain attributes, such as not being formed to allow them to be readily collapsed or to be collapsed such that they are compact and unobtrusive in size and appearance.  
         [0010]     Numerous collapsible bags are known. Some are made of thick, heavy materials, such as canvas, and are designed to be folded. Others are made of lightweight nylon so that they may be compacted into a very small size, often by stuffing them into an accompanying, small stuff sack. Yet, the designs of such bags generally do not allow them to be attached to a travel case in a collapsed state and, while still so attached, be expanded for advantageous use as described in this application.  
         [0011]     One bag has been proposed to allow collapsing and expanding while attached to a travel case, but its design does not allow it to be collapsed to and maintained in an unobtrusive size. Similarly, bags have also been disclosed in other fields which might seem adaptable to the advantageous use described here, but they also are too large even when collapsed. Just as a proper structural design for a 50 story building is not simply an upsized design for a 10 story building, at some point a change in size from a large device to small one entails more than simply a change in dimensions of constituent components.  
         [0012]     Because of the small size of the pouches of the present invention, as well as features allowing embodiments to be quickly and easily deployed and re-collapsed, and in between having items quickly stored in and retrieved from it, dynamics come into play that are different from those affecting the design of larger bags. For example, larger items of a given thickness can be folded more times than can smaller items of the same thickness, as shown by research undertaken by Britney Gallivan. While her work was performed for a high school project, it has been widely cited. From her work, she derived the following formula: L=((π*t)/6)*(2 n +4)*(2 n −1), where L is the minimum possible length of the material, t is the material&#39;s thickness, and n is the number of folds possible in one direction.  
         [0013]     Assuming that folding a large pouch and a small pouch the same number of times and according to the same pattern generates identical increases for each in the aggregate thickness of the folded material, through often this is not correct, relative to each pouch&#39;s height and width the thickness of the small pouch can be much greater. So, to minimize the actual and perceived thickness of a small pouch when it is collapsed, a small pouch&#39;s design must incorporate different construction features. For example, while some devices disclosed elsewhere utilize substantial stiffener components in each of a their folding sections, those embodiments of the present invention that utilize stiffeners utilize modest, foldable ones.  
         [0014]     The number of times and the direction in which a device is folded to minimize its size when in its collapsed state also affects the design of the systems used to attach it to a travel case, construction methods and components used to make the device easy to deploy and collapse, and particularly the materials used to make the pouch component of the device. For example, a device that simply folds or rolls up and down to move to and from its deployed and collapsed states can entail different attachment strap design challenges than does a device which folds up and down as well as side to side. Collapsing the latter device entails compound folds—layers of material folded over each other in one direction which are then folded in another direction—while that is not true for the former bag. Additionally, it can be more difficult to neatly fold a device which uses compound folds, and as suggested above this is especially true as the device becomes smaller in size.  
         [0015]     The present invention can be advantageously practiced using extremely lightweight material for constructing its pouch component. For example, the pouch of the invention can be constructed of nylon fabric weighing less than 45 grams per square meter, and the total weight of the embodiment can be as little as 30 grams.  
         [0016]     While lightweight nylon and comparable materials are generally not regarded as being stiff, when used to make a device of the invention appropriate sized for many situations, often smaller than 14 centimeters square, the pouch of the invention can be constructed to be stiff enough without a full complement of stiffeners to be folded in a geometric pattern readily and quickly, even using only one hand and while the device is dangling from a piece of luggage.  
         [0017]     Another design challenge for a storage device which collapses to a very small size and which also must serve the purposes of the present invention is that the pouch opening must be of at least a certain minimum size so that the user can place his hand into the bag to retrieve his items. Based on an analysis of glove industry data, the practical minimum opening size of a slit-style opening is approximately 5.25″, which would nevertheless make it somewhat difficult for someone with a large hand and basically impossible for someone with an XL hand size to reach into the pouch. Unless the pouch is designed to be folded side to side, the collapsed size of the bag would necessarily be substantially larger than the collapsed size of the devices of the invention.  
       OBJECTS  
       [0018]     It is an object of the invention to make it easier and more efficient for individuals to be processed with their personal items through a security checkpoint.  
         [0019]     It is also an object of the invention to provide individuals with a device to hold their pocket items and other personal items when such items are to be submitted for scanning, scanned, and then retrieved.  
         [0020]     It is also an object of the invention to provide to individuals such a device that is easy to quickly deploy, place items therein, retrieve items therefrom, collapse, and secure in a collapsed state.  
         [0021]     It is also an object of the invention that such device be lightweight, small, and compact when it is in its collapsed state.  
       GENERAL DESCRIPTION OF SELECT FEATURES OF THE INVENTION  
       [0022]     A number of novel elements of the invention are available for incorporation into select embodiments of the invention to help them meet objects of the invention.  
         [0023]     The choice and use of closure mechanisms for the storage pouch in devices of the invention depend not simply on the effectiveness of a given such mechanism. Rather, they also are based on the goal of promoting minimization of size of the devices when they are collapsed. For collapsible storage devices in which the pouch and its closure mechanism are folded along vertical axes, a portion of the closure mechanism is typically folded upon itself. Since the closure mechanism can be the thickest component of the device, design features which reduce such over-folding can reduce the finished thickness of the collapsed device.  
         [0024]     Related-art collapsible storage devices are constructed with the opening of their storage volume between their front and back walls at the top and a closure mechanism incorporated as a means to close that opening.  
         [0025]     Such storage devices which utilize a zipper for that function do so with the zipper&#39;s planar surfaces oriented horizontally. This makes compact folding of such a device side-to-side troublesome as a zipper can best be folded compactly when its planar surfaces are brought against each other in a face-to-face fold and for these zippers that would generally entail a lateral folding. The devices of the invention that are constructed to be folded geometrically side-to-side and that utilize a zipper orient the zipper so that it will be folded in a face-to-face fashion, though actual face-to-face contact is often minimized. This is generally accomplished by forming the opening and installing the zipper in the front wall near its top edge.  
         [0026]     For a top-opening storage device that uses a hook-and-loop closure mechanism, such as the brand-name product Velcro®, the design challenge is different. While such a closure mechanism is typically incorporated in a way that a side-to-side fold of the device would cause an acceptable face-to-face folding of the closure mechanism, such closure mechanisms are relatively thick and therefore present a special design challenge when crafting a device that collapses to a very small size. One novel approach of the invention comprises installing this type of closure mechanism in an offset pattern so that there is a reduction in the amount of overfolding. Another novel approach of the invention for reducing the total thickness of a collapsible storage device is to set this type of closure mechanism at a bias. This approach also works with other closure mechanisms, including continuous mechanisms such as zippers and zipper-like mechanisms used with food storage bags and the like. Or, if the closure mechanism is set at a regular angle, folding at an irregular angle can achieve the same beneficial result.  
         [0027]     Additionally, minimization of the thickness of the collapsed device of the invention is aided in some embodiments by constructing the device to minimize the total thickness of material sandwiched with the thickest part of the closure mechanism. One approach of the invention comprises irregular folding patterns, such as when a zipper will be divided by folding into two segments, arranging the construction so that the division, rather than being 50-50, favors the side on which the slider is present so that the slider will overshoot the opposite end of the zipper and come to rest on a non-zipper element of the device.  
         [0028]     For embodiments of the invention that comprise folding the device side-to-side to collapse it, placement of the strap or straps which connect the device to a travel case entails additional challenges. For example, affixing an attachment strap system at a location on the device that appropriately balances the pouch when the pouch is holding items can result in the collapsed device looking obtrusive, such as in a bottom-heavy T-shape. The invention discloses devices that provide appropriate balance for the pouch when in use yet an advantageous presentation of the device when it is collapsed.  
         [0029]     Some device embodiments of the invention that comprise side-to-side folding teach a novel design whereby the strap system is splayed at the cover of the device when the device is deployed but is unified when the device is collapsed. Related art teaches the use of splayed or spread-apart straps to meet balance concerns for a container device when it is carrying items, but because their strap arrangement are generally unchanged when the device is collapsed, they offer a disadvantageous opening created by such straps and the body of the device that can easily be snagged along the way.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0043]      FIGS. 1-1D  show a folding pouch with a tri-fold cover and a strap for engaging a luggage handle, a preferred embodiment of the invention.  
         [0044]     A storage device  15  is shown which comprises a cover mechanism  20  and a pouch  40 .  
         [0045]     The cover mechanism comprises a left section  20   a , a middle section  20   b , and a right section  20   c , a fastener-a  21   a , shown in  FIG. 3 , which cooperates with a fastener-b  21   b  to keep the cover closed. The cover mechanism further comprises an upper edge  24   a , a lower edge  24   b , an edge left  24   c , an edge right  24   d , as well as an inside  25  and an outside  26 .  
         [0046]     The cover mechanism additionally comprises a strap  70  which facilitates a secure engagement of the storage device with handle  10  through a strap void  70   a . In order to engage the handle, the strap can be made temporarily discontinuous by means of a buckle  75 . The strap comprises a first strap end  73   a  and a second strap end  73   b , as well as an inner surface  71 , which comprises a first surface  72   a  and a second surface  72   b.    
         [0047]     The strap is affixed to the cover mechanism, being joined at the and the first and second strap ends of the strap to a first location  74   a  and a second location  74   b , respectively, of the cover proximate its upper edge  24   a.    
         [0048]     The cover further comprises a window  28  through which an ID card, if inserted behind said window in a card-holding structure (not shown), can be seen.  
         [0049]     Pouch  40  comprises a front wall  46 , a back wall  48 , an opening  60 , and a zipper  80 . It further comprises a top segment  40   a , a mid-top segment  40   b , a mid-lower segment  40   c , and a lower segment  40   d , interspersed with a top crease  45   a , a middle crease  45   b , a bottom crease  45   c . Pouch  40  also comprises a top edge  42   a , a bottom edge  42   b , a left edge  42   c , and a right edge  42   d.    
         [0050]     Additionally, pouch  40  comprises a seam  47 , which affixes the pouch to the cover mechanism, and a pivot point  47   a  which can aid the folding of the pouch, namely mid-top segment  40   b  to top segment  40   a.    
         [0051]     Front wall  46  comprises a top front wall segment  46   a , a mid-top front wall segment  46   b , a mid-lower front wall segment  46   c , and a lower front wall segment  46   d , while back wall  48  comprises a back wall mid-top segment  48   b  and a back wall lower segment  48   d . Wall segments  46   c - d  and a majority of wall segment  46   b  is constructed from a see-through mesh material, making it easier to visually inspect personal items in the pouch and for the person suing the pouch to more easily discern that all items have been removed from it.  
         [0052]     Opening  60  comprises a first end  61   a  and a second end  61   b.    
         [0053]     Zipper  80  comprises an opened end  81   a , a closed end  81   b , a teeth component  83 , a slider  84 , and a pull  85 .  
         [0054]     As shown in  FIG. 1A , device  15  is shown substantially deployed with pouch  40  substantially unfolded, but slightly folded in order to highlight fold structures of the pouch and related structures.  
         [0055]     When device  15  is deployed compared to when it is stowed, strap ends  73   a - b  are splayed rather than in a unified arrangement and strap surfaces  72   a - b  are both facing forward rather than being opposed. This splaying is arranged by opening the cover mechanism which remains unified, without portions of the cover being split off from one another. This splaying can provide both actual and perceived stability for device  15  when it is in use holding a number of personal items.  
         [0056]     The creases  45   a - c  make it easy to quickly fold pouch  40 , combining in a fan-fold arrangement the segments  40   a - d  of the pouch. It can be advantageous to use material for at least one wall of the pouch that will retain a crease, to structurally guide folding of the pouch. Using material with such a feature can also be advantageous by visually indicating the intended fold lines, for with a material as thin as that which can be used for device  15  and with a pouch that is not much larger than the size of many hands, knowing where the folding should take place can encourage proper, faster folding. This takes into account, among other things, that while the device encourages proper folding, it cannot resist improper folding.  
         [0057]     While not shown here, the invention can advantageously include a thin, though relatively stiff interfacing in lower segment  40   d , affixed either to its front or back, though affixing to its front can be preferred as it can discourage billowing of the pouch when it is being folded. Such interfacing can fill most of the length and width of segment  40   d  and stop just below bottom crease  45   c , thereby providing a break or pivot point that can help guide the intended fold at such location. Such interfacing can also extend just over crease  45   c  to reinforce it as a fold. Another alternative entails only using a narrow piece of interfacing at the fold and a centimeter into each adjoining segment.  
         [0058]     It should be noted that the center of gravity of device  15  is not directly below a point half-way between first location  74   a  and second location  74   b , as might be expected. While, in this way, the strap can be seen to be off-center, for a device of this size and for this purpose, the extent of being off center is not substantial relative to the benefits that this deign can facilitate, such as quick folding and a compact and unified device when it is stowed.  
         [0059]     Normally a wide storage device that is designed to be folded more than simply at a medial vertical line is likely to require inward folding of segments serially from each side. While such a series of folding is not necessarily bad for the applications discussed here, it can be more difficult to accomplish, especially with one hand, and can require substantially stiffer pouch segments, resulting in a bulkier stowed device. Devices of the invention that comprise an offset, asymmetrical arrangement are able to be folded in a series of side-to-side folds which in the settings typical of the applications discussed here can be much easier to do.  
         [0060]      FIG. 1B  shows device  15  with all of the pouch segments  40   a - d  folded up. The strategic location of pivot point  47   a  can be seen, located along top crease  45   a.    
         [0061]     Also apparent is the advantageous integration of zipper  80 . As the zipper slider is the thickest component of the pouch, here the effect of this thickness on the thickness of the stowed device is reduced by folding the pouch without covering the slider. Also, because the zipper is set at a bias and the device can be stowed with the zipper at opened end  81   a , the zipper teeth component folds more easily and compactly, as an open zipper is easier to fold and the angle at which the zipper is set minimizes the extent of zipper teeth overlapping zipper teeth.  
         [0062]      FIG. 1B  also shows first axis  27   a  and second axis  27   b , at which the device  15  and its pouch  40  are to be folded side-to-side. While the crease retaining capability of the fabric used to construct the pouch provides some folding guidance her as well, also significant is the folding memory of the material used to construct the case, as well as the design structure of the device that encourages an alignment of the two ends of the strap, one over the other, as the device is toggled to its stowed state.  
         [0063]     As shown in  FIG. 1C , left section  20   a  of the cover mechanism has been folded over, left to right, creating said alignment of the strap ends. Also, edge left  24   c  has become a pivot point for the last fold of the device, namely right section  20   c  folding right-to-left. It should also be noted that these two side-to-side folds of the cover also folds the pouch.  
         [0064]      FIG. 1D  shows device  15  fully stowed. With the case closed, it is wrapped around the folded pouch. It does create a top portal  68   a  and bottom portal  68   b , which provide a very limited view of the folded pouch.  
         [0065]      FIG. 1D  also shows that when closed the device is compact and unified, in that it is small with a trim profile and presents a snagging hazard comparable to that of a standard luggage ID tag.  
         [0066]      FIG. 1E  shows a clip  90  which is a device for attaching storage device  15  to a pants belt, as an alternative to strap  70 . It comprises a front  92   a , a back  92   b , and a top  92   c , and an engagement space  91  is defined by these structures to receive a belt. The clip also comprises a back surface  93  at which it is to be affixed to outside  26  of cover mechanism  20  at its middle section  20   b . A configuration of the storage device with clip  93  can better meet the needs of someone who has reason to go through a security checkpoint but does not have reason to carry a briefcase, suitcase, or the like.  
         [0067]      FIGS. 2-2E  show views of a folding device with an offset zipper and bottom-up roll cover. Note than in  FIG. 2  and  FIG. 2A , in which the embodiment is shown in its collapsed state, the two strap ends, of the strap that is used to connect the device to the travel case, are attached to the device&#39;s cover, and wrapped within it, so as to be immediately proximate to each other. As the device is shown being deployed in  FIGS. 2B-2C , the straps are released to form a stability-enhancing triangle, described above. As an aid to keep the straps together when the device is being collapsed and is secured in that state, a small flap (the material above where the straps are connected to the device&#39;s case) was formed to fold over so as to make a sandwich of portions of the strap, with the flap and a proximate portion of the case located above and below the straps. As with certain other embodiments of the invention, the orientation of the strap to the rest of the device changes when the device is taken from its closed state to its deployed state.  
         [0068]      FIG. 2E  shows a portion of the inside front surface of the pouch. This drawing highlights the focused use of interfacing to promote the intended functioning of the device while minimizing its collapsed thickness. The fusible interfacing has been affixed to the pouch using heat-set glue and sewing. The pouch has four vertical sections for folding side-to-side and the interfacing has been affixed as four pieces, one for each section. While in the embodiment shown in  FIGS. 1-1C  the interfacing stops at the horizontal fold line, in this embodiment the interfacing extends above the fold line enough to help set the crease in this material so as to promote the ready folding of the pouch. For this purpose, it is not necessary to extend the interfacing up to the next fold line so as to cover the entire middle section of the pouch.  
         [0069]      FIGS. 3-3C  show views of a stuff bag with bottom-opening case. This bag is designed to be randomly folded, that is stuffed, into its case. The bag is attached via an intermediate cloth strip to the inside of the case so that the bag can be fully extended from the case. As an alternative the bag could be directly attached, such as by sewing, to the inside surface of the cover flap.  
         [0070]     As with all of the embodiments shown here that are not permanently affixed to a travel case, the bag is deployed, used, and collapsed without having to alter the bags connection to the travel case.  
         [0071]     The bag exits its case through an opening in the bottom of the case. The bag shown is made of 1.3 ounce ripstop nylon coated with Teflon®. If the bag were to come out of an opening at the tope of the case, the cover flap, which could flop down, could interfere with use of the bag. For a shorter flap, this might be less of a concern, and the objects of the invention could be met with this embodiment being flipped 180 degrees to locate the opening at the top. Here, however, a long flap is used to provide an unobstructed component of the case that can be easily imprinted or embroidered—even after the bag, with its case, has been manufactured.  
         [0072]     While the strap attachment and the embodiment could be considered to form an awkward T shape, discussed above, the case here is preferably between one inch and 3 inches square, so this does not present the same problem as would be presented by a bag or case that is five or more inches along its top edge.  
         [0073]      FIGS. 4-4A  show views of a stuff bag with a thin material stuff case. The bag is attached to its stuff case via a strip of cloth.  
         [0074]      FIGS. 5-5E  show views of a folding pouch with an offset zipper and side-roll cover. This pouch, with its case, is similar to the one shown in  FIGS. 2-2E . Here, the cover wraps around from the side, not up from the bottom. So, while the strap ends here also change their positions relative to each other as the device is deployed, a loose segment of the strap need not be enclosed within the case when the device is collapsed.  
         [0075]     An example of the novel folding of the invention is shown in  FIG. 5C . While the pouch is generally divided into three segments that run horizontally, the bottom two are formed to be smaller than the top one so that when the bottom two segments are folded up they do not cover the zipper&#39;s slider and pull.  
         [0076]     Also, while not shown, the pouch is attached to its case not only along a portion of its top edge, but also by sewing along a portion of the pouch&#39;s top horizontal fold line at the back piece of the pouch. By attaching the pouch to the case at the specific area, the sewn seam acts as a pivot point when the pouch is being folded up, thereby promoting orderly folding of the pouch.  
         [0077]      FIGS. 6-6C  show views of a unified material folding device in a wallet-shaped form. This embodiment also incorporates an ID card which is hidden when the device is fully collapsed.  
         [0078]      FIGS. 7-7D  show views of a folding device with an offset zipper. When closed, the device hangs in a diamond-like orientation as to the travel case to which it is attached. Yet when the device is deployed, the strap is located just above the device&#39;s center line. This device also comprises a clear plastic window to hold an ID card. And, as can be seen in  FIG. 7C , the device is attached to its case not only along portions of its top edge, but also at a fold line through the device&#39;s back piece.  
         [0079]      FIGS. 8-8B  show views of a folding device with offset hook-and-loop strips and a rigid plastic case. The device also comprises a translucent mesh panel at its front.  
         [0080]      FIG. 9  shows a view of a deployed folding pouch, standing alone, comprising alternative approaches to avoiding folding over the zipper slide. The pouch is divided into three segments running horizontally and two running vertically. The creases are heat set and no stiffener is used. While the zipper is not offset, the creases set in the pouch are offset. These offset creases promote folding of the pouch such that when the bottom two segments are folded up they do not cover the zipper. And, the vertical fold line is off center to the right, so that after the pouch is folded up and then side-to-side, the zipper&#39;s slider and pull are not covered.  
         [0081]      FIGS. 10-10C  show a bag of the invention integrated with a rolling suitcase. The bag is stored in its collapsed state in a zippered case. While the zippered case shown here is affixed to the front of the suitcase, it can be affixed to other surfaces of the suitcase or inset with access provided from the outside of the suitcase at other surfaces of the suitcase. The bag has a zipper at its top edge and it is attached to the suitcase via two tethering straps, the straps being affixed at a surface inside of the zippered case.  FIG. 10C  shows the bag, with items having be placed inside and the bag being closed, as the suitcase and bag would be oriented when going through a scanner machine.  
         [0082]     While there are known examples of small cases which are stored within pockets of larger cases and to which the small cases are tethered, such examples are lacking in relation to the present invention, and particularly to the embodiment shown in  FIGS. 10-10C . In those known examples, the small cases, such as a change purse, are not collapsible. And they are not stored in a pocket sized primarily to contain them—that is, the change purse is connected via a tether to the general, main compartment of a pocketbook, so when the change purse is needed, it must be hunted out from within the main compartment.  
         [0083]     While the embodiment shown in  FIGS. 10-10C  comprises a bag with a dedicated, integrated, zippered pocket directly accessible from the outside of rolling suitcase, the present invention anticipates any confined space serving a comparable function, such as an unzippered pocket, a set of straps, or a single wide strap affixed to the inside surface of a larger zippered pocket and dedicated primarily to holding the bag in its collapsed state.  
         [0084]     It should be noted that no matter how or where in the suitcase the bag is stored when in its collapsed state, it is important that, if that storage space does hold additional items that are not affixed to the suitcase, provision be made to prevent those items from falling out when the entire case is going through the scanner machine process. A benefit of the bag being stored in a dedicated, externally accessible pocket is that the pocket&#39;s opening need not be closed other than to keep stored the collapsed bag.  
         [0085]      FIGS. 11-11B  shows a bag of the invention more fully integrated with a rolling suitcase than the bag just described. The bag here is accessed for deployment via a zippered panel that is swung open to cause the bag to expand. The bag shown here is constructed of pleated material, generally in an accordion-like structure. The way in which the bag is connected to the suitcase, both when stored and when in use, is structurally substantial, as at least one face of the bag is completely affixed to the suitcase at all times. As shown here, and as aided by the pleat design, the bag can be collapsed for storage by simply swinging the covering panel shut and securing its zipper. The bag has its own closure device, a zipper on its top surface.  
         [0086]     While expandable holding structures, affixed to the outside of suitcases, and which collapse to essentially zero storage volume, are known, they do not include a separate closing device, such as the zippers shown here. Such expandable structures offer non-closable top openings, such as for holding a water bottle or sports accessory.  
         [0087]     A variation of the design shown here would comprise a similar panel which swings down to allow a pleated bag, or an unstructured bag, to be deployed. With such a drop-down panel, a simple non-gusseted bag could be used, similar to ones described above. Also, to help make the process of storing the bag quick and easy, the bag could be made of a stretchy material, such as Spandex™. This way, the bag could be constructed to lie flat when empty, but deployed, with a substantial portion of its back surface connected to the suitcase, and so would be very easy to put away by simply closing its covering, swinging panel—that is, there would be no loose fabric to be gathered up, yet the stretchy material would allow the bag to expand adequately to meet its purpose.  
         [0088]      FIGS. 12-12C  show a unified nylon folding device with an offset hook-and-loop closure device. The device does not comprise a discrete case, but rather is formed to provide the same enclosing function as the case described above. The nylon folding device has a tab combined with a strip of hook-and-loop material which joins to a complementary strip affixed to the back of the bag, as shown in  FIG. 12C . As can be seen in  FIG. 12B , a stiffener system, specifically fusible interfacing, has been affixed to the inside face of the front piece of the bag. Also, a portion of the strap used to attach the bag to a travel case is shown.  
         [0089]     The pouch is formed with fold lines that divide it into nine segments, providing some structure for an ordered folding—up twice and then to the side twice. While the stiffener system runs across all of the bottom pouch segments, the stiffener has been formed in three separate pieces so that when the bag is folded to the side, which are compound folds, the stiffener will not then be folded over and add to the bags thickness in its collapsed state.
