Benefits of technology

[0007]According to a first aspect of the invention there is provided a variable volume bag comprising a main chamber, the main chamber having an external wall with an inside face and an outside face, at least part of the external wall being moveable between at least one folded position, in which the useable volume of the main chamber and the external size of the bag is reduced, and at least one extended position in which the useable volume of the main chamber and the external size of the bag is increased, a material join disposed substantially at or proximate a fold position for facilitating movement to the folded position, and retaining means for securing the external wall in the folded position.
[0008]The bag is advantageous because it is versatile in size and internal volume. The internal space of the bag can be fully utilised in both the folded and extended positions. The material join of the fabric of the bag provides a natural break and fold line, which as described further below, serves to assist the user in moving the bag from the extended to folded position.
[0009]The means for securing the external wall in the folded position facilitates providing a bag of compact appearance when the additional volume provided by the extended position(s) is not required.

Problems solved by technology

For example, a briefcase is smart and designed for use in an office-type environment but it is unlikely to have the additional capacity required for carrying grocery items following an impromptu visit to the supermarket after work.
Additionally, when the briefcase is then used in the supermarket environment, the carrying position of holding the briefcase by a short handle is unsuitable for heavy loads.
However, placing one or more items into an attaché case or a known general purpose backpack can lead to property damage, especially for electrical items such as MP3 players.

third embodiment

[0059]Referring now to FIGS. 11 and 12, bag is indicated generally at 100. Common reference numerals will be used to describe parts in common with the two previous embodiments of bag 10, 80. The bag 100 includes folding side portions 26, 28 constructed in exactly the same way as the side portions of the previous two embodiments. However, this bag is much smaller in size.

first embodiment

[0060]A single pocket 102 is provided on the front of the bag 12, which is accessed by a single zip. Other carrying options include a single strap 104 which cooperates with a flap 106 at the lower side 22 of the bag. Both the strap 104 and flap 106 may be tucked away inside the sleeve 52, which is similar to that of the first embodiment, and the strap and flap are held together by a male and female connector. A further method of carrying the bag is by means of a shoulder strap 108, as shown in FIG. 11, which attaches in conventional manner to triangular shaped loops 88 provided on the upper and lower sides of the side portion 28. These are only accessible, when the side portion 28 is in the extended state.

[0061]It will be appreciated that in all of the embodiments disclosed, either one or both of the side portions can be provided in the folded or extended state. The elements and teachings of the various illustrative embodiments may be combined in whole or in part in some or all of t...

The bag is typically selected according to the likely contents and the environment in which it will be used. For example, a briefcase is smart and designed for use in an office-type environment but it is unlikely to have the additional capacity required for carrying grocery items following an impromptu visit to the supermarket after work. Thus a separate grocery bag would be required.[0004]Additiona...
