A collapsible container or reservoir including at least one side wall region (4-7) and a basal wall region or base (8) surrounding a containment region having an upper opening or mouth (10) surrounded by a perimeter flange (9) at the ends of the side walls distal from the basal wall region, the side
A collapsible container or reservoir including at least one side wall region (4-7) and a basal wall region or base (8) surrounding a containment region having an upper opening or mouth (10) surrounded by a perimeter flange (9) at the ends of the side walls distal from the basal wall region, the side walls include a region of concertina (14) whereby, upon squeezing or compression of the side walls, the basal wall region of the container is compacted more, relative to the extent of the upper opening. The container can be used for dispensing foods such as pet food, sauces, yogurt, custard or the like, or other liquids or semi fluid materials such as oil, grease, glue or resin.

1. A container having an upper portion and a lower portion comprising: a containment region including at least one side wall, a basal wall and at least one pair of opposed regions of said side wall extending from said basal wall;an upper opening at least partially surrounded by a flange disposed at an end of said at least one side wall distal from said basal wall;a plurality of pre-formed features reducing resistance to compression of said lower portion compared to said upper portion configured to accommodate substantially complete buckling of said basal wall to bring said opposed regions of said side wall substantially adjacent one another upon squeezing of said opposed regions of said side wall; andsaid pre-formed features including at least one surface relief on said basal wall and a region of concertina in said side wall. 2. The container as claimed in claim 1, wherein said at least one side wall is concertinaed in opposed regions of said at least one side wall. 3. The container as claimed in claim 1, wherein the region of concertina of said at least one side wall extends in a direction between the basal wall and said flange. 4. The container as claimed in claim 1, wherein said region of concertina extends from said basal wall upwards towards said flange. 5. The container as claimed in claim 1, wherein said at least one surface relief includes a region of concertina. 6. The container as claimed in claim 5, wherein the region of concertina of said basal wall extends in a direction parallel to a plane parallel to which the at least one side wall concertina features extend. 7. The container as claimed in claim 1, wherein said container is of a quadrilateral plan shape and includes four side walls extending between said flange and said basal wall. 8. The container as claimed in claim 7, wherein said four side walls include a first pair of opposed side walls in which the region of concertina of said side walls are defined. 9. The container as claimed in claim 1, wherein said region of concertina of said at least one side wall includes at least one trough formed in said at least one side wall and said at least one trough extends in a direction between said flange and said basal wall. 10. The container as claimed in claim 1, wherein said region of concertina of said at least one side wall includes at least two troughs and a ridge intermediate of two troughs, formed in said at least one side wall and the at least two troughs and the ridge extend in a direction between said flange and said basal wall. 11. The container as claimed in claim 1, wherein said region of concertina of said at least one side wall includes a series of ridges and troughs extending in a direction between said flange and said basal wall. 12. The container as claimed in claim 9, wherein each said trough extends from said basal wall towards said flange and is terminated by a web that transitions the at least one side wall between said trough and said flange. 13. The container as claimed in claim 12, wherein each said web is a planar triangular web with one base side parallel to said flange and one apex in the trough. 14. The container as claimed in claim 12, wherein each said web is a planar triangular web with one base side parallel to and contiguous said flange and one apex in the trough. 15. The container as claimed in claim 9, wherein said trough is one defined by said at least one side wall to extend towards said containment region. 16. The container as claimed in claim 1, wherein a partition wall is included in the containment region to define two partition wall separated compartments, said partition wall extending perpendicular to a direction of squeezing. 17. The container as claimed in claim 1, wherein said flange includes a zone of weakness to allow for a fracturing of the flange. 18. The container as claimed in claim 8, wherein said flange includes a zone of weakness to allow for a fracturing of the flange and wherein said zone of weakness is located intermediate non-concertina opposed side walls. 19. The container as claimed in claim 7, wherein said opposed side walls that include said concertina, at a given height above the basal wall, vary in distance from each other by virtue of the concertina. 20. The container as claimed in claim 19, wherein a variation of distance is symmetrical about a vertical mid-plane intermediate of said opposed side walls that include said concertina. 21. The container as claimed in claim 1, wherein said container is a food container. 22. The container as claimed in claim 7, wherein said concertina of said side walls meet at said basal wall. 23. The container as claimed in claim 6, wherein said side walls are curved towards each other from said opening and meet at said basal wall. 24. The container as claimed in claim 6, wherein said other pair of side walls are planar sidewalls. 25. The container as claimed in claim 1, wherein said container is an open top container. 26. The container as claimed in claim 6, wherein said opening is the same or larger in size than said basal wall. 27. The container as claimed in claim 1, wherein said flange extends in a plane parallel to a direction of squeezing. 28. The container as claimed in claim 1, wherein said flange projects outwardly from said opening and beyond the at least one side wall. 29. A set of containers, wherein each container having an upper portion and a lower portion, each container includinga containment region including at least one side wall, a basal wall and at least one pair of opposed regions of said side wall extending from said basal wall;an upper opening at least partially surrounded by a flange disposed at an end of said at least one side wall distal from said basal wall;a plurality of pre-formed features reducing resistance to compression of said lower portion compared to said upper portion configured to accommodate substantially complete buckling of said basal wall to bring said opposed regions of said side wall substantially adjacent one another upon squeezing of said opposed regions of said side wall; andsaid pre-formed features including at least one surface relief on said basal wall and a region of concertina in said side wall;said containers being integrally formed with each other. 30. The set of containers as claimed in claim 29, wherein the set of containers is integrally formed in an injection moulding, vacuum forming, rotary moulding or blow moulding process. 31. The set of containers as claimed in claim 29, wherein the set of containers is formed from a single sheet of material in a deep drawing thermoforming machine.
