The device comprises a container comprising a base member and a cover member being sealingly connected with each other along the circumference of the container, a compartment for receiving the substance, and an open ended pocket area into which the substance is transferable from the compartment, and a cannula having an internal passageway being in fluid communication with the pocket for dispensing the substance. ## Claims ### Claim 1 A device for storing and dispensing a flowable substance, comprising: a container comprising a base member and a cover member being sealingly connected with each other along the circumference of the container, wherein said base member is formed as a sheet, at least one compartment for receiving said substance, and an open ended pocket area into which said substance is transferable from said at least one compartment, and a cannula having an internal passageway being in a fluid communication with said pocket for dispensing said substance, wherein said cannula is a separate component having a first end and a second end, said first end being adapted for insertion into said open end of said pocket area, and a portion separating said compartment from said pocket, said separating portion comprising a passage area adapted to be selectively opened by pressure effective on said passage area for placing said compartment in communication with said pocket. ### Claim 2 (depends on 1) The device of claim 1, wherein said first end comprises an extension part having a portion with an increased cross-section. ### Claim 3 (depends on 2) The device of claim 2, said extension part having a cross-sectional shape comprising sharp edges in the plane between the base member and the cover member, and preferably comprises a rhombic or fin-like cross-sectional shape. ### Claim 4 (depends on 1) The device of claim 1, wherein said extension part comprises at least one portion having an increased diameter. ### Claim 5 (depends on 1) The device of claim 1, wherein said extension part comprises a portion being tapered along the length thereof, with the thickness of the tapered portion decreasing towards said first end. ### Claim 6 (depends on 5) The device of claim 5, wherein said tapered portion comprises an U-shaped sealing area on each of the opposing surfaces of said tapered portion, the legs of said U-shaped sealing areas extending towards said first end and being connected at the edge of said first end. ### Claim 7 (depends on 1, 2, 3, 4, 5, 6) The device of any of claims 1 to 6, wherein said first end is attached to said open ended pocket area by a heat seal, a press fit, and/or an adhesive. ### Claim 8 (depends on 1) The device of claim 1, wherein said first end comprises an extension part adapted for being attached to the outer surface of said container. ### Claim 9 (depends on 8) The device of claim 8, wherein said extension part is attachable to said cover member. ### Claim 10 (depends on 8) The device of claim 8, wherein said extension part comprises a first portion and a second portion being inclined relative to said first portion. ### Claim 11 (depends on 8, 9) The device of claim 8, 9, or 10, wherein said cannula is inclined relative to said extension part. ### Claim 12 (depends on 8, 9, 10) The device of any of claims 8 to 10, wherein said internal passageway of said cannula extends through said extension part. ### Claim 13 (depends on 12) The device of claim 12, wherein said extension part comprises a recess in the surface that is attachable to said container, said recess being adjacent to and surrounding said passageway opening. ### Claim 14 (depends on 13) The device of claim 13, wherein said recess is ring shaped. ### Claim 15 (depends on 13) The device of claim 13, wherein said extension part comprises a raised portion adjacent to and surrounding said passageway opening, said recess surrounding said raised area. ### Claim 16 (depends on 1) The device of claim 1, said separate cannula being attached to said cover member, whereby said fluid communication with said pocket is established through said cover member. ### Claim 17 (depends on 16) The device of claim 16, wherein said cannula comprises a dosing system having a variable volume, preferably a bellow. ### Claim 18 (depends on 17) The device of claim 17, wherein said cannula further comprises an applicator at said second end for applying said substance to a treatment area. ### Claim 19 (depends on 18) The device of claim 18, wherein said applicator comprises bristles being integrally formed with said second end of said cannula, or comprises a foamed material, a non-woven material, or a plurality of fibres incorporated into said second end of said cannula. ### Claim 20 (depends on 19) The device of claim 19, wherein said internal passageway of said cannula further comprises flow resistors, preferably formed by structured surfaces, constricted portions, and/or orifices. ### Claim 21 (depends on 2, 3, 4, 5, 6) The device of any of claims 2 to 6, said extension part further comprising stiffening elements extending away from said extension part. ### Claim 22 (depends on 1) The device of claim 1, wherein said base member sheet is a deep-drawn sheet formed of a polypropylene layer, an aluminium layer, and a polyethylene layer. ### Claim 23 (depends on 1) The device of claim 1, said cover member being formed as a sheet, preferably being formed of a polyethylene terephthalate layer, an aluminium layer, and a polyethylene layer. ### Claim 24 (depends on 1) The device of claim 1, said cover member being formed as a plastic part, preferably as an injection moulded part. ### Claim 25 (depends on 1) The device of claim 1, comprising two or more compartments for holding different substances, and a passage area adapted to be selectively opened for placing said compartments in communication with each other prior to dispensing the mixed final substance. ### Claim 26 (depends on 1) The device of claim 1, said cannula further comprising a mixer. ### Claim 27 (depends on 26) The device of claim 26, said mixer comprising mixing helixes or elements providing flow resistance. ### Claim 28 (depends on 1) The device of claim 1, further comprising a handle. ### Claim 29 (depends on 1) The device of claim 1, wherein the container is pre-filled. ### Claim 30 (depends on 1) The
