Abstract

A bag 101 is provided with releasable closure members (117, 123 fig. 1), such as a zip, by means of which the bag 101 can be assembled in either one of two configurations (Figures 2A and 2B). Using different zips to form the bag (117, 123) may provide a bag of different depth, and since each side may comprise different surface decoration, so changing the configuration may also alter the bag's appearance. The bag may be formed from a combination of flexible and rigid panels. Handles (696, fig.6), shoulder straps (567, fig. 5, 693, fig.6) and pockets (573, fig.5, 697, 698, fig.6) may be provided for use in either configuration.

Description

ABAG

This invention relates to reversible bags and methods of assembly of reversible bags. More specifically but not exclusively the invention relates to reversible bags for use in applications such as carrying laptops, as rucksacks, as shoulder bags, as camera bags, or as bags fulfilling multiple functions such as a backpack with a laptop compartment.

It is well known that consumers may find reversible products such as clothing and bags desirable, especially where turning the product inside out provides an alternate function or appearance. Currently however reversible bags for many purposes are not available or have shortcomings.

In particular reversible bags are often cumbersome to reverse. This is frustrating for the user and may also result in the bag having a reduced life if seams and material are stressed during reversal. Additionally there are often compromises with reversible bags; for example features that would be useful in both configurations (such as, zipped pockets, shoulder straps, handles and/or additional pockets) are only accessible in one configuration, have compromised performance in one or both configurations, or are not included as being incompatible with reversible bags.

The present invention seeks to mitigate the above mentioned shortcomings.

According to a first aspect of the invention a reversible bag is provided, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, the bag being provided with one or more releasable closure members, the closure members being suitable for operation when the bag is in either one of the first and second configurations. A reversible bag may be convenient for the user as it may increase the utility of the bag through flexibility. By providing a means for closing the bag when it is in either of its reversed configurations the utility and convenience of the bag may be further increased.

It may be that the bag has substantially rigid panels, to provide protection for items placed in the bag, and flexible panels, to make reversal of the bag possible.

In some embodiments the bag may be formed with the flexible panels forming one or more corner areas of the bag and the substantially rigid panels forming surfaces between the corner areas. This may be advantageous where it is desirable that a greater proportion of the surface area of the bag is substantially rigid to provide a greater area of protection.

In other embodiments the bag may be formed with the substantially rigid panels forming one or more corner areas of the bag and the flexible panels forming surfaces between the corner areas. This may be advantageous where it is anticipated that protection at the corner areas is paramount, perhaps due to an expectation that most impacts will occur at these points.

Preferably the flexible panels are fabricated from neoprene or closed cell foam, but other suitable materials may be used.

Preferably the substantially rigid panels are fabricated from a stiff polyethylene board or a stiffer variety of closed cell foam than that that might be used for the flexible panels, but other suitable materials may be used.

It may be that the bag has substantially rigid panels to provide protection for items placed in the bag, an interface between one or more of the panels having one or more joints to make reversal of the bag possible.

Preferably the joints are formed at corner areas of the bag.

It may be that the joints are provided by one or more creases formed in the substantially rigid panels. Alternatively the joints may be formed by one or more gaps between the substantially rigid panels. Creases and gaps might be used in the same bag.

Preferably a flexible material is provided between the gaps. The flexible material may be attached to the substantially rigid panels by stitching, adhesive tape or any other suitable means.

Preferably the substantially rigid panels are fabricated from a stiff polyethelene board.

It may be that the joints are disguised and/or covered on both sides of the bag. This may prevent the joints from being seen and/or felt where this is deemed undesirable. The disguise may be provided by a foam layer on either side of the joints. The foam may also double as padding.

It may be that the bag is provided with the one or more closure members provided on selected seams, the selected seams being chosen such that the bag is disassemblable from the first configuration or the second configuration upon release of the closure members, into a substantially flat template configuration, and is asemblable upon securing of the closure members into the first three dimensional configuration or the second three dimensional configuration.

The use of releasable closure members along selected seams of the bag, such that during reversal of the bag a substantially flat template configuration is produced, may result in reduced stress on the bag seams during reversal (i.e. when compared with a pull-through' reversible bag where seams are not released). Additionally it may allow the reversal process to be performed more easily. As will become apparent the present reversal system may also offer greater scope for aesthetic and functional differences between the first and second three dimensional configurations.

It should be noted that in this context a flat template', is concerned with the main structure of the bag and takes account of the main structural seams of the bag, A third dimension introduced by additional pockets or other augmenting features are not considered part of the template. The key aspect of the flat template is that there is no trace of the main pocket previously created by the bag. Consequently there should be no folds in the material of the template or additional material extending out of the plane of its surface. Such folds or additional material might create significant kinks in the material or cavities between layers of material, giving it a three dimensional configuration.

It may be that the overall dimensions of the first and second configurations are different. In this way the height and/or width and/or depth of a main pocket in the bag may be altered by reversing the bag from one configuration to the other. This may be particularly useful where different items of the same type may have different dimensions, for example laptops. In this case the same bag may be suitable for customers with differently sized laptops.

It may be that the overall height of the first and second configurations is different.

It may be that the overall width of the first and second configurations is different.

It may be that the overall depth of the first and second configurations is different.

A facility for the alteration of the height, width or depth of the bag may be particularly useful in particular instances (e.g. a change in width may be particularly useful for differently sized laptops, whereas a change in depth may be advantageous where different numbers of files are to be carried).

Preferably a change in any one or more of the overall height, width or depth is achieved by the provision of alternative, differently sized sets of one or more panels, one set of panels being provided for use during assembly of the first configuration the other being provided for use during the assembly of the second configuration.

It may be that at the selected seams between parts of the bag that are to be secured to one panel of the set of panels for use during assembly of the first configuration or the set of panels for use during assembly of the second configuration, the said parts of the bag are provided with separate closure means for each of the alternative panels. This may allow for each panel to have a dedicated closure means for securing it to the relevant part of the bag when desired. This may make assembly and disassembly easier and less complicated.

It will be appreciated that embodiments of the present invention are not limited to use in particular types of bag. Embodiments may for example be advantageous in laptop cases, rucksacks, shoulder bags, camera bags, or bags fulfilling multiple functions such as a backpack with a laptop compartment. Additionally the bag itself may be manufactured from a wide array of suitable materials and these may be relatively flexible or relatively rigid.

Preferably the appearance and/or functionality of the first configuration is different to that of the second configuration. In this way the aesthetic appeal of the bag and/or its utility may be changed. This may eliminate the need for the purchase of an additional bag.

Preferably at least part of the difference in appearance and/or functionality of the first configuration from the second configuration is caused by alternative sides of the flat template being provided with different surface designs. Such designs might for example include differing artwork, colours, materials, textures or reflective safety panels.

Preferably at least part of the difference in appearance and/or functionality of the first configuration from the second configuration is caused by alternative sides of the flat template being provided with different additional storage layout and/or size and/or function. Each configuration may for example have some external pockets that differ in their position relative to the other three dimensional configuration.

Preferably each closure means is a zip assembly. A zip assembly may offer a reliable closure between parts of the bag that is nonetheless easy to release during disassembly. Nonetheless closure means of any other suitable type may be used, for example hook and ioop faster arrangements, or a series of button fasteners.

Preferably one or more of the zips are of the type that are operable from both sides. This may facilitate release and re-securing of the zips when the first or second configurations are being assembled or disassembled.

Alternatively however a pair of zips, each designed to be operable from one side only, may be provided.

It may be that the bag is provided with one or more support means such as buckles, clips, clasps or the like. Such support means may complement the securing function of one or more of the closure means and/or help to maintain the shape of the bag in the first and/or second configurations.

Some embodiments may be provided with a handle suitable for use in both of the first and second configurations.

Other embodiments may be provided with a pair of handles, one for use when the bag is in each of the first and second configurations.

It may be that the bag is provided with one or more shoulder straps. The shoulder straps may be suitable for use when the bag is in the first configuration and when it is in the second configuration. This may be achieved by allowing the shoulder straps to be pulled through to the exterior of the bag regardless of the configuration in which it is arranged.

Alternatively the straps may be detachable from one side and re-attachable to the other.

Preferably the bag is provided with a removable storage sleeve. A removable storage sleeve may be used for locating and providing additional padding for items placed in the bag regardless of whether the bag is in the first or second configuration. The sleeve may be particularly convenient where the item(s) to be protected might be vulnerable to damage by dirt or other detritus (such as a laptop) that may be present inside the bag. It should be noted that the likelihood of dirt or detritus being present on the interior surfaces of the bag may be increased in view of said surfaces potentially having previously been on the exterior of the bag when reversed and so potentially exposed to dirt and moisture etc. Preferably the bag is provided with one or more additional internal or external pockets when in the first configuration and/or the second configuration. Additional pockets may increase the functionality and/or aesthetic appeal of the bag.

It may be that the same additional pocket is one of internal or external when the bag is in the first configuration and the other when the bag is in the second configuration.

It may be that access is provided to the same additional pocket internally and externally of the bag regardless of whether it is in the first or second configuration. This may provide a high level of convenience as the additional pocket need not be pulled through when the bag is reversed.

It may be that one or more of the additional pockets are divided into two or more compartments. This might for example be advantageous where access is provided to the pocket when the bag is in both configurations, but that it is desirable for the contents of the pocket to be segregated according to the configuration in which the bag was arranged when items were placed in the pocket. This may be particularly advantageous where the pocket is positioned within a wall of the bag.

It may be that one or more of the additional pockets are reversible so as they are internal or external pockets for both the first and second configurations. This may be advantageous where the intended function or aesthetic of a pocket is exclusively particularly suited to either internal or external positioning.

It may be that one or more of the additional pockets are provided with one or more gusseted walls to facilitate reversal of the pocket. In this way the pocket may be easily turned inside Out when the bag is reversed to allow the pocket to be positioned as required.

It may be that one or more of the additional pockets are detachable. In this way a pocket that is useful in one of the first and second configurations may be attached when the bag is assembled in that configuration but removed when the other configuration is used.

It may be that detachable padding is provided, attachable to the bag in one or both of its configurations. This may be particularly advantageous where for example a fragile item (such as a laptop is sometimes but not always carried in the bag).

According to a second aspect of the invention a method of assembling a reversible bag in one of two configurations is provided comprising providing a reversible bag, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, the bag being provided with one or more releasable closure members, the closure members being suitable for operation when the bag is in either one of the first and second configurations, and releasing the closure members and turning the bag inside out and optionally securing the closure members.

According to a third aspect of the invention a reversible bag is provided, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, the bag being provided with a removable storage sleeve. A removable storage sleeve may be used for locating and providing additional padding for items placed in the bag regardless of whether the bag is in the first or second configuration. The sleeve may be particularly convenient where the item(s) to be protected might be vulnerable to damage by dirt or other detritus (such as a laptop) that may be present inside the bag. It should be noted that the likelihood of dirt or detritus being present on the interior surfaces of the bag may be increased in view of said surfaces potentially having previously been on the exterior of the bag when reversed and so potentially exposed to dirt and moisture etc. According to fourth aspect of the invention a reversible bag is provided, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, where the bag is provided with one or more additional pockets and where the additional pockets are accessible from outside of the bag regardless of whether it is in the first or second configuration.

According to a fifth aspect of the invention a reversible bag is provided, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, the bag having substantially rigid panels to provide better protection for items placed in the bag, and flexible panels to make reversal of the bag possible.

Preferably the substantially rigid panels are fabricated from a stiff polyethelene board or a stiffer variety of closed cell foam than that that might be used for the flexible panels, but other suitable materials may be used.

According to a sixth aspect of the invention a reversible bag is provided, the bag being reversible between a first configuration and a second configuration, where the reversing action is to turn the bag inside out, the bag having substantially rigid panels to provide better protection for items placed in the bag, one or more of the panels having one or more joints to make reversal of the bag possible.

Preferably the joints are formed at corner areas of the bag.

It may be that the joints are provided by one or more creases formed in the substantially rigid panels. Alternatively the joints may be formed by one or more slits in the substantially rigid panels. Creases and slits might be used in the same bag.

Preferably a flexible material is provided between the slits. The flexible material may be attached to the substantially rigid panels by stitching, adhesive tape or any other suitable means.

Embodiments of the invention will now be described, by way of example only, with reference to the accompanying figures, in which: Figure 1 is a schematic view of an embodiment according to the invention in its flat template configuration; Figure 2A is a schematic view of the embodiment of figure 1 in its first configuration; Figure 2B is a schematic view of the embodiment of figure 1 in its second configuration; Figure 3 is a perspective view of an embodiment of the invention during assembly of the bag from the flat template configuration to one of its first and second configurations; Figure 4 is a perspective view of another embodiment of the invention in one of its first and second configurations; Figure 5 is a perspective view of another embodiment of the invention in one of its first and second configurations; Figure 6A is a perspective view of another embodiment of the invention in its first configuration; Figure 6B is a perspective view of the embodiment of figure 6A; Figure 7A is a perspective view of another embodiment of the invention during reversal of the bag from a first configuration to a second configuration; Figure 7B is a perspective view of the embodiment of figure 7A in its second configuration; Figure 8 is a perspective view of another embodiment of the invention in its first configuration; Figure 9A is a perspective view of another embodiment of the invention in its first configuration; Figure 9B is a schematic view illustrating the corner panels 936 of the embodiment of figure 9A.

Referring first to figure 1 a reversible bag is generally provided at 101.

As shown the bag 101 is in a disassembled state and is thus in a flat template configuration 103. The template 103 is flat in the sense that it has a depth of only material thickness. There are no folds in the material or additional material extending out of the plane of the surface of the template 103.

The template 103 has a rectangular main body 105 with a pair of short sides 107 and a pair of long sides 109. The main body 105 is responsible for forming a front panel llOa, a base panel hUb, a back panel hOc, a top panel hOd and a front flap hOe. Extending outwards from each long side 109 are short side panels 111 and long side panels 113. Each short side panel 111 has side edges 112a and a distal end edge 112b. Each long side panel 113 has side edges 114a and a distal end edge 114b. In the orientation of the template 103 shown in figure 1 the short side panel 111 overlies the long side panel 113. The short 111 and long 113 side panels have substantially the same width but the long side panels 113 can be seen extending beyond the short side panels 111 due to their greater length.

Each of the short 111 and long 113 side panels meet the main body 105 at a fold line 115. The pair of short side panels 111 form a set of panels for use during assembly of a first configuration and the pair of long side panels 113 form a set of panels for use during assembly of a second configuration.

A pair of first zip assemblies are generally provided at 117. It will be appreciated that each of the pair of first zip assemblies 117 are identical and therefore only the left hand assembly (as viewed with the template 103 in the orientation of figure 1) is described below. Zip assembly 117 has two co-operable rows of teeth. The first row 119 extends along long side 109 of the front panel llOa and base panel ilOb of the main body 105. The second row 121 extends along the side edge 112a nearest base panel liOb and distal end edge 112b. The base (not shown) of the zip assembly 117 is provided at the intersection between the long side 109 and the short side panel 111.

A pair of second zip assemblies are generally provided at 123. It will be appreciated that each of the pair of second zip assemblies 123 are identical and therefore only the left hand assembly (as viewed with the template 103 in the orientation of figure 1) is described below. Zip assembly 123 has two co-operable rows of teeth. The first row 125 extends along long side 109 of the front panel llOa and base panel ilOb of the main body 105, adjacent first row 119 of zip assembly 117. The second row 127 extends along the side edge 114a nearest base panel liOb and distal end edge 114b. The base (not shown) of the zip 123 is provided at the intersection between the long side 109 and the long side panel 113.

Referring now to figures 1, 2A and 2B, assembly and disassembly of the bag 101 will now be described. Starting from the flat template configuration 103 of figure 1, a user has the option of assembling the bag 101 into a first configuration or a second configuration. In the first configuration the depth of the bag is less than the depth of the bag in the second configuration. The dimension in question can be clearly seen in figures 2A (showing the bag 101 in the first configuration having depth A-A) and 2B (showing the bag 101 in the second configuration having depth B-B), where depth A-A is less than depth B-B.

The difference in the depth is created by reversing the bag 101 to form either the first or second configuration. If it is desirable that the bag 101 has a smaller depth, the pair of first zip assemblies 117 are actuated (securing co-operating teeth rows 119 and 121). Securing of the zip assemblies 117 will urge the template 103 into the first configuration as shown schematically in figure 2A. In this first configuration the base panel ilOb takes a smaller share of the main body 105 and the front panel llOa takes a larger share. The respective sizes of the base panel ilOb and front panel llOa are dictated by the length of the short side panel 111 and this also therefore results in the shorter depth A-A.

As will be appreciated returning the bag 101 to the template configuration 103 is achieved by actuation of the first zip assemblies 117 to release them. Thereafter the bag 101 may be reassembled as described above or else into the second configuration, If it is desirable that the bag 101 has a larger depth, it is reversed (essentially turning the first three dimensional configuration inside out) and the pair of second zip assemblies 123 are actuated (securing co-operating teeth rows 125 and 127). Securing of the zip assemblies 123 will urge the template 103 into the second configuration as shown schematically in figure 2B. In this way surfaces previously forming the interior of the bag 101 now form its exterior and vice versa. In this second configuration the base panel liOb takes a larger share of the main body 105 and the front panel llOa takes a smaller share. The respective sizes of the base panel ilOb and front panel llOa are dictated by the length of the long side panel 113 and this also therefore results in the shorter depth B-B. As can be seen in figure 2B it also results in the front panel llOa having a reduced height.

Returning the bag 101 from the second configuration to the template configuration 103 is achieved by actuation of the second zip assemblies 123 to release them. The user may then once again select between assembly of the first or second configurations.

it will be appreciated that in the first and second configurations the front panel llOa, base panel ilOb, back panel hOc, top panel hOd, front flap hOe and respectively the two short side panels 111 or the two long side panels 113, define a main pocket (not shown) there between. The depth of the main pocket is dictated by whether the short side panels 111 or the long side panels 113 are used. In the first configuration the long side panels 113 are redundant, and are contained within the main pocket. In the second configuration the short side panels 111 are redundant, and are contained within the main pocket. It should also be understood that several seams, joining material areas, may exist throughout the template 103 and that the perimeter areas where first zip assemblies 117 and second zip assemblies 123 are provided are selected seams having one or more releasable closure members (in this case the zip assemblies 117 and 123).

As will be appreciated, the embodiment of figures 1, 2A and 2B allow for the dimensions of the bag 101 to be altered by reversing it. Additionally differing surface decoration on either side of the template 103 means that the bag 101 alters in appearance between the first and second configurations.

Referring now to figure 3 an embodiment of the invention is shown. The embodiment incorporates the feature whereby the depth of the reversible bag may be changed by reversing the bag between its two configurations (as discussed in relation to figures 1, 2A and 2B). Where appropriate similar features to those already discussed are given like reference numerals in the series 300.

The embodiment of figure 3 includes co-operable clasps 329 attached to the short side panels 311 and extending perpendicular to distal end edges 31 2b.

The embodiment also includes an interior detachable sleeve 337, attached to the back panel (not shown). Additional storage space is provided by a zipped pocket 339 which is formed within the front flap 310e and is accessible from the exterior of the bag 301 when in the first configuration. Co-operable clasps 329 are engageable once the bag 301 is in the first configuration to provide support to first zip assemblies 317 and to assist in maintaining the shape of the bag 301.

Referring now to figure 4 an alternative embodiment of a reversible bag according to the invention is provided. Where appropriate similar features to those already discussed are given like reference numerals in the series 400. In the embodiment shown in figure 4 the bag 401 is a reversible laptop case. The principal of the bag 401 is similar to the bag 101 (the appearance of the bag 401 can be altered by reversing it between first and second configurations with an intermediate template configuration). The feature whereby the depth of the reversible bag may be changed by reversing the bag between its two configurations is not present however.

The bag 401 is shown in its first configuration and has a base panel 410b, a back panel 410c, a top panel 410d, a front flap 410e and two side panels 441. Between these parts is defined a main pocket 443.

In the embodiment of figure 4 a single zip assembly 445 is provided. The zip assembly 445 is of the type that are operable from both sides. The zip assembly 445 has two co-operable rows of teeth. The first row 447 extends around the perimeter of a combination of the base panel 410b and side panels 441. The second row 449 extends around the perimeter of a combination of the back panel 410c, top panel 410d and front flap 410e.

The base (not shown) of the zip assembly 445 is provided at the intersection between the back panel 410c and one of the side panels 441.

Only a single zip assembly 445 is required because the zip assembly runs around the entire perimeter of the bag template (not shown) and also because there is only one set of side panels 441. Because there is only one set of side panels 441, there is no dimension change that results from the reversal of the bag 401. It will be apparent however that the facility for dimensional changes could be employed with the laptop case if desired. In the embodiment of figure 4 the appearance of the bag 401 changes depending on whether the bag 401 is in the first or the second configuration. The functionality of the bag 401 is designed to be substantially the same in both configurations, including the provision of a gusseted pocket 451 (shown in both its possible configurations). The gusseting on the pocket 451 allows for it to be reversed when the bag 401 is reversed. It can therefore perform the same function and be positioned in similar positions for both the first and second configurations. Fixed gusseted pocket flaps 452 are provided on both the internal and external sides (as shown in the bag configuration of figure 4) for use with the gusseted pocket 451 when its configuration makes this appropriate.

It should be understood that several seams, joining material areas, may exist throughout the bag 401 and that the perimeter areas where zip assembly 445 is provided is a selected seam having a releasable closure member (in this case the zip assembly 445).

Referring now to figure 5 an alternative embodiment of a reversible bag according to the invention is provided. Where appropriate similar features to those already discussed are given like reference numerals in the series 500. In the embodiment shown in figure 5 the reversible bag 501 is a different embodiment of a reversible laptop case. The principal of the bag 501 is similar to the bag 401. The bag 501 is shown in its first configuration and has a front panel 510a, a base panel (not shown), a back panel 510c, a front flap 510e and two side panels 541. Between these parts is defined a main pocket 543.

In the embodiment of figure 5 a pair of zip assemblies (not shown) are provided, one associated with each of the side panels 541. Since each zip assembly is identical only one is described below, but it will be understood that the explanation is applicable to both zip assemblies, each associated with one of the side panels 541. The zip assembly is of the type that are operable from both sides. The zip assembly has two co-operable rows of teeth. The first row (not shown) extends along a short edge 553 of the front panel 510a and along a short edge 555 of the base panel. The second row (not shown) extends around a base edge 557 and a side edge 559 of the side panel 541. The base (not shown) of the zip assembly is provided at the corner intersection 561 of the base panel, back panel 510c and the side panel 541. In addition to the zip assemblies the bag 501 is provided with a first 563 and second 565 set of co-operable clasps. The co-operable clasps 563, 565 complement the securing function of the zip assemblies.

The bag 501 is provided with a shoulder strap 567. The shoulder strap has two roots 569 each of which is attached to a top edge 571 of one of the side panels 541. Front 573 and side 575 additional pockets are also provided. Front pocket 573 is provided within the wall of the front panel 510a and has internal access via a first zip (not shown) and external access via a second zip 577. It will be appreciated that when the bag 501 is in its second configuration, the first zip will be for external access and the second zip 577 will be for internal access. Within the front pocket 573 is a dividing panel (not shown), such that articles placed into the front pocket 573 via the first zip and the second zip 577 are separate. The side pocket 575 is provided within the wall of one of the side panels 541. The side pocket 575 is accessible both internally and externally via zipped entry points (one 579 only shown). In contrast to the front pocket 573 the side pocket 575 does not have a dividing panel, so articles placed in the side pocket 575 via alternative zipped entry points are not separated.

Because there is only one set of side panels 541, there is no dimension change that results from the reversal of the bag 501. It will be apparent however that the facility for dimensional changes could be employed with the bag 501 if desired. Jn the embodiment of figure 5 the appearance of the bag 501 changes depending on whether the bag 501 is in the first or the second configuration. The functionality of the bag 501 is designed to be substantially the same in both configurations.

It should be understood that several seams, joining material areas, may exist throughout the bag 501 and that the perimeter areas where zip assemblies are provided are selected seams having releasable closure members (in this case the zip assemblies).

Referring now to figures 6A and 6B a reversible bag 601 is provided according to the invention. In the embodiment of figures 6A and 6B the bag 601 is a rucksack. The principal of the bag 601 is similar to the bags 101, 301, 401 and 501 in that the appearance of the bag 601 can be altered by reversing it between first and second configurations. It is different however in the sense that no flat intermediate template configuration is created during reversal. The bag 601 is shown in its first configuration and has a base part 681 and a top closing part 683. A rim 685 of the base part 681 and a perimeter region of the top closing part 683 are provided with a zip assembly 687 of the type that are operable from both sides. The zip assembly 687 has two co-operable rows of teeth.

The first row 689 extends around the rim 685 of the base part 681. The second row 691 extends around a perimeter region of the top closing part 683. The base (not shown) of the zip assembly 687 is provided at one intersection between the base part 681 and the top closing part 683.

The bag 601 is provided with a pair of shoulder straps 693 attachable to the base part 681.

The bag 601 is also provided with a handle 696 extending from the base part 681. Upper 697 and lower 698 additional pockets are also provided. Both upper 697 and lower 698 additional pockets are provided within the wall of the top closing part 683 and are accessible from both sides of the top closing part 683 via zipped entry points 699.

As can be seen, the embodiment of figures 6A and 6B has different surface decoration on its interior and exterior surfaces. As will be appreciated therefore, when the bag 601 is reversed into a second configuration the appearance of the bag 601 will change. Reversal of the bag 601 from the first configuration into the second configuration is achieved by pulling or pushing the base part 681 through the opening left by the top closing part 683 when it is open. Thereafter the zip assembly 687 can be operated externally of the bag 601 in view of it being operable from both sides. The pair of shoulder straps 693 can be attached to the exterior of the rucksack 601 on suitably provided attachment points (provided on both sides of the bag 601). The position and operation of the upper 697 and lower 698 additional pockets does not change following reversal. This is because access to each pocket is provided both internally and externally. An additional handle (not shown) is also provided, positioned on the exterior of the rucksack 601 when it is in the second configuration.

It will be appreciated that in the embodiment shown in figures 6A and 6B, the functionality of the bag 601 remains substantially unchanged regardless of whether it is in the first or the second configuration. The appearance of the bag 601 is changed however, and in the embodiment shown this is the primary motivation for reversing the bag 601.

It should be understood that several seams, joining material areas, may exist throughout the bag 601 and that the perimeter areas where zip assembly 687 is provided are selected seams having a releasable closure member (in this case the zip assembly 687).
