A device for dispensing a dental material, comprising: a first and a second compartment (11, 12) formed between interconnected sheet-like layers (21, 22), the first compartment at an inactivated stage encapsulating a first flowable component of the dental material; the second compartment at an inactivated stage encapsulating a second flowable component of the dental material; a reservoir for jointly holding at least parts of the first component and the second component at an activated stage; a dispensing outlet which opens the reservoir; a first seal openably sealing the first compartment and the second compartment at the inactivated stage from each other; a second seal openably sealing the second compartment and the reservoir at the inactivated stage from each other; each of the first seal and the second seal being formed by the layers (21, 22) in a non-permanent sealing area (16, 17) in which the layers are interconnected such that they are disconnectable in consequence of forcing a component of the dental material between the layers (21, 22); wherein the capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open; characterised therein that the dental material has a predetermined desired mixing ratio of the first component and the second component, and the device contains a first amount of the first component and a second amount of the second component at a ratio of the amounts which is different from the desired mixing ratio; wherein the first compartment has a first capacity for the first component which is greater than a second capacity for the second compartment; and wherein the desired mixing ratio is defined by a quantity n of the first component relative to a quantity m of the second component, and wherein the first amount of the first component present in the first compartment corresponds to a quantity of n + m and the second amount of the second component present in the second compartment corresponds to a quantity of m. a first and a second compartment (11, 12) formed between interconnected sheet-like layers (21, 22), the first compartment at an inactivated stage encapsulating a first flowable component of the dental material; the second compartment at an inactivated stage encapsulating a second flowable component of the dental material; a reservoir for jointly holding at least parts of the first component and the second component at an activated stage; a dispensing outlet which opens the reservoir; a first seal openably sealing the first compartment and the second compartment at the inactivated stage from each other; a second seal openably sealing the second compartment and the reservoir at the inactivated stage from each other; each of the first seal and the second seal being formed by the layers (21, 22) in a non-permanent sealing area (16, 17) in which the layers are interconnected such that they are disconnectable in consequence of forcing a component of the dental material between the layers (21, 22); wherein the capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open; characterised therein that the dental material has a predetermined desired mixing ratio of the first component and the second component, and the device contains a first amount of the first component and a second amount of the second component at a ratio of the amounts which is different from the desired mixing ratio; wherein the first compartment has a first capacity for the first component which is greater than a second capacity for the second compartment; and wherein the desired mixing ratio is defined by a quantity n of the first component relative to a quantity m of the second component, and wherein the first amount of the first component present in the first compartment corresponds to a quantity of n + m and the second amount of the second component present in the second compartment corresponds to a quantity of m.
