The invention proposes to dispense a substance from a container filled with a single portion of a substance. The container comprises a preformed deformable body, preferably made of sheet material, defining a filling cavity which body has an opening and an integral planar circumferential rim surrounding said opening, which opening is closed by a cover sheet which is sealed to the circumferential rim by means of a circumferential sealing seam. The container with the substance is opened by making use of the deformability of the cover sheet. A support surface supports the cover sheet except at the position of a recess. The recess is positioned at least over a part of the circumferential sealing seam. Upon compression of the container body the substance is pressurized and the cover sheet bulges out into the recess such that the sealing seam is broken at the location where the bulge is formed resulting in the container being open.

1. A container containing a liquid drink preparation substance, said container comprising: a preformed deformable body defining a filling cavity filled with the liquid drink preparation substance; anda cover sheet,said preformed deformable body having: an opening at said cavity,an integral planar circumferential rim surrounding said opening; anda dispensing region separated from said opening by said planar circumferential rim,said opening, said planar circumferential rim and said dispensing region being covered by said cover sheet, which is sealed to said planar circumferential rim at a circumferential sealing seam, anda dispensing passage for the liquid drink preparation substance being formed between the dispensing region and the cover sheet, said circumferential sealing seam including a seam portion upstream of and contiguous with said dispensing passage, said seam portion being configured to permit flow of said liquid drink preparation substance across said seam portion and along said dispensing passage between said cover sheet and said dispensing region, responsive to predetermined compression of said body,said cover sheet including a planar portion covering at least said dispensing region;said dispensing region being a flat dispensing region having an edge;said dispensing passage including at least two outwardly directed sealing seams sealing said cover sheet to said flat dispensing region;said outwardly directed sealing seams extending, at a distance from one another, from said circumferential sealing seam to said edge of said dispensing region; andsaid edge of the dispensing region between said two outwardly directed sealing seams being provided with a recess lying in the plane of the flat dispensing region. 2. The container according to claim 1, wherein said seam portion has a pointed portion of which the point is directed towards the filling cavity such that upon compression of the container said seam portion starts to break at the pointed portion. 3. The container according to claim 1, wherein the outwardly directed sealing seams are substantially parallel. 4. The container according to claim 1, wherein the dispensing region is shaped as an extending tab. 5. The container according to claim 4, wherein a gripping tab is provided at the circumferential rim. 6. The container according to claim 5, wherein the gripping tab is situated diametrically opposite the extending tab. 7. The container according to claim 1, wherein the dispensing region has a part near its edge with a decreasing thickness towards the edge. 8. The container according to claim 7, wherein the thickness of the dispensing region at the edge is substantially equal to the thickness of the cover sheet. 9. The container according to claim 1, wherein the edge of the dispensing region at the recess has a curved form. 10. The container according to claim 9, wherein the edge of the dispensing region at the recess has a V-shape. 11. The container according to claim 1, wherein the dispensing passage defined between the outwardly directed sealing seams is provided with one or more obstructions for the flow of substance exiting the container. 12. The container according to claim 1, wherein the dispensing passage is provided with one or more further weak seals. 13. The container according to claim 1, wherein the end of the dispensing passage at the edge of the dispensing region is open. 14. The container according to claim 1, wherein the deformable body is formed of a plastic material. 15. The container according to claim 14, wherein the plastic material is polystyrene. 16. The container according to claim 1, wherein the deformable body is formed of a metal. 17. The container according to claim 1, wherein the cover sheet is made of foil material. 18. The container according to claim 1, wherein the cover sheet is made of a multilayer material. 19. The container according to claim 1, wherein the cover sheet is preformed. 20. The container according to claim 1, wherein the deformable body is formed by at least one of vacuum forming and thermo forming. 21. The container according to claim 1, wherein the deformable body comprises a bottom and a side wall extending upwardly from the bottom. 22. The container according to claim 1, wherein the deformable body is corrugated so as to facilitate compression of the container. 23. The container according to claim 1, wherein the circumferential rim is provided with one or more positioning protrusions formed by a depression in the rim for positioning the container in a dispensing apparatus. 24. The combination of the container according to claim 1 and a dispensing apparatus comprising compression means for compressing the deformable body. 25. The combination according to claim 17, wherein the dispensing apparatus comprises receiving means for holding the container and a supporting surface for supporting the cover sheet of the container, wherein the supporting surface is provided with a recess at the location of the dispensing passage of the container, such that upon pressurization of the substance in the container by means of the compressing means, the cover seal is allowed to bulge out into the recess such that the seam portion is broken and the substance can flow through the dispensing passage.
