An oral care implement, comprising: a handle for grasping; a head including at least one tooth cleaning element; a reservoir for storing a flowable substance; at least one outlet (15, 130) disposed on the head; and a capillary channel fluidly coupling the reservoir to the outlet (15, 130), the capillary channel comprising: a first wicking member (122, 163) formed of a wicking material and defining a first flow section (120, 160); and a second wicking member (123, 165) formed of a wicking material and defining a second flow section (121, 161), the second wicking member (123, 165) being fluidly coupled to the first wicking member (122, 163); wherein the flowable substance flows via capillary action from the first wicking member (122, 163) to the second wicking member (123, 165) through a flow restrictor (150, 170) at a rate of flow that is different than a rate of flow through the first or second wicking members (122, 163); characterised in that the flow restrictor (150, 170) comprises one of: a notched area formed between the first and second wicking members (122, 123, 163, 165); a non-permeable sealant heat-fused or applied to at least part of a cross-sectional end portion between the adjacent first and second flow sections (120, 121, 160, 161) to seal at least some of the pores; a reduced cross-sectional flow area disposed between the first and second wicking members (122, 123, 163, 165); a unidirectional or bidirectional flow gate or valve between the first and second wicking members; a porous membrane between the first and second wicking members; a perforated partition plate between the first and second wicking members; and a diaphragm between the first and second wicking members. a handle for grasping; a head including at least one tooth cleaning element; a reservoir for storing a flowable substance; at least one outlet (15, 130) disposed on the head; and a capillary channel fluidly coupling the reservoir to the outlet (15, 130), the capillary channel comprising: a first wicking member (122, 163) formed of a wicking material and defining a first flow section (120, 160); and a second wicking member (123, 165) formed of a wicking material and defining a second flow section (121, 161), the second wicking member (123, 165) being fluidly coupled to the first wicking member (122, 163); a first wicking member (122, 163) formed of a wicking material and defining a first flow section (120, 160); and a second wicking member (123, 165) formed of a wicking material and defining a second flow section (121, 161), the second wicking member (123, 165) being fluidly coupled to the first wicking member (122, 163); wherein the flowable substance flows via capillary action from the first wicking member (122, 163) to the second wicking member (123, 165) through a flow restrictor (150, 170) at a rate of flow that is different than a rate of flow through the first or second wicking members (122, 163); characterised in that the flow restrictor (150, 170) comprises one of: a notched area formed between the first and second wicking members (122, 123, 163, 165); a non-permeable sealant heat-fused or applied to at least part of a cross-sectional end portion between the adjacent first and second flow sections (120, 121, 160, 161) to seal at least some of the pores; a reduced cross-sectional flow area disposed between the first and second wicking members (122, 123, 163, 165); a unidirectional or bidirectional flow gate or valve between the first and second wicking members; a porous membrane between the first and second wicking members; a perforated partition plate between the first and second wicking members; and a diaphragm between the first and second wicking members. a notched area formed between the first and second wicking members (122, 123, 163, 165); a non-permeable sealant heat-fused or applied to at least part of a cross-sectional end portion between the adjacent first and second flow sections (120, 121, 160, 161) to seal at least some of the pores; a reduced cross-sectional flow area disposed between the first and second wicking members (122, 123, 163, 165); a unidirectional or bidirectional flow gate or valve between the first and second wicking members; a porous membrane between the first and second wicking members; a perforated partition plate between the first and second wicking members; and a diaphragm between the first and second wicking members.
