A refillable flexible container, light weight and compact when empty, with a wide mouth to make it easy to keep clean. A range of optional cases and lids will provide a range of dispensing options for varying uses and needs.
The containers could be made from recycled plastics and with a collection point (and discount incentive) at the point of sale for worn-out containers, all plastic used to produce them could then be recycled by the manufacturers.
This container would reduce the need for disposable containers for people on the go, such as cyclists, who want to keep the bulk and weight of what they carry minimal. It could also be developed for shoppers wanting to keep what they carry to the shops minimal if their journey is tied in with other activities and tasks.
