The container is generally cylindrical, and is made of resiliently-deformable plastics material. The workhead is attached to one end of the container, and is provided with a pair of internal ducts which connect the interior of the container to the outlets. The other end of the container is closed off by a screw cap. An air-intake valve is provided in the screw cap, the air-intake valve being such as to open when the pressure in the container is less than that outside the container. The air-intake valve is constituted by a plurality of valve openings passing through the screw cap, a valve seat formed on the interior surface of the screw cap, and a resiliently-deformable valve closure member which overlies the valve seat and the valve openings. ## Claims ### Claim 1 A hair-tinting implement comprising a tinting-medium container, and a workhead provided with a tinting medium outlet, the container being generally cylindrical and being made of resiliently-deformable material, the workhead being attached to one end of the container and being provided with an internal duct which connects the interior of the container to the outlet, the other end of the container being closed off by a sealing member, an air-intake valve being provided in the sealing member, the air-intake valve being such as to open when the pressure in the container is less than that outside the container, wherein the air-intake valve comprises at least one valve opening passing through the sealing member, a valve seat formed on the interior surface of the sealing member, and a resiliently-deformable valve closure member which overlies the valve seat and said at least one valve opening, wherein the sealing member is provided with an integral socket projection which extends into the container and defines a recess in the sealing member, said at least one valve opening being provided in the socket projection. ### Claim 2 (depends on 1) An implement according to claim 1, wherein the workhead is provided with a comb, a spike-like hair spreader, and a flat brush. ### Claim 3 (depends on 2) An implement according to claim 2, wherein respective tinting-medium outlets are provided both on the hair spreader and the flat brush, and the workhead is provided with a pair of internal ducts which connect the interior of the container to the two tinting-medium outlets. ### Claim 4 (depends on 3) An implement according to claim 3, wherein the tinting-medium outlets can be closed selectively or simultaneously. ### Claim 5 (depends on 4) An implement according to claim 4, wherein the workhead is provided with a valve member which is effective to close either or both of the tinting-medium ducts. ### Claim 6 (depends on 3) An implement according to claim 3, wherein a flat, resilient nozzle is arranged within the flat brush, the lips of the nozzle, which bear resiliently against each other to close the nozzle mouth, being separable from each other by the pressure of the tinting-medium. ### Claim 7 (depends on 1) An implement according to claim 1, wherein the container is made of resiliently-deformable plastics material. ### Claim 8 (depends on 1) An implement according to claim 1, wherein the sealing member is made of plastics material. ### Claim 9 (depends on 1) An implement according to claim 1, wherein a screw cap comprises the sealing member, the screw cap having a screw-threaded edge portion which surrounds the air-intake valve and engages a complementary screw-threaded portion at said other end of the container. ### Claim 10 (depends on 1) An implement according to claim 1, wherein the socket projection is provided with a plurality of valve openings, all of which are overlaid by the valve closure member. ### Claim 11 (depends on 1) An implement according to claim 1, wherein the container tapers from said other end towards said one end. ### Claim 12 A hair-tinting implement comprising a tinting-medium container, and a workhead provided with a tinting medium outlet, the container being generally cylindrical and being made of resiliently-deformable material, the workhead being attached to one end of the container and being provided with an internal duct which connects the interior of the container to the outlet, the other end of the container being closed off by a sealing member, an air-intake valve being provided in the sealing member, the air-intake valve being such as to open when the pressure in the container is less than that outside the container, wherein the air-intake valve comprises at least one valve/opening passing through the sealing member, a valve seat formed on the interior surface of the sealing member, and a resiliently-deformable valve closure member which overlies the valve seat and said at least one valve opening, wherein a flat disc comprises the resilient valve closure member, and wherein a cup-shaped member is formed integrally with the sealing member, the cup-shaped member accommodating the flat disc. ### Claim 13 (depends on 12) An implement according to claim 12, wherein the valve seat is a knife-edged annular rib formed integrally with the base of the cup-shaped member, the valve seat surrounding said at least one valve opening. ### Claim 14 (depends on 12) An implement according to claim 12, wherein the flat disc is held by a releasable plastics clamping member inserted into the cup-shaped member. ### Claim 15 (depends on 14) An implement according to claim 14, wherein the clamping member is a clamping ring. ### Claim 16 (depends on 14) An implement according to claim 14, wherein the clamping member is provided with groove-like recesses on that surface bearing against the flat disc. ### Claim 17 (depends on 12) An implement according to claim 12, wherein the sealing member is made of plastics material. ### Claim 18 (depends on 12) An implement according to claim 12, wherein a screw cap comprises the sealing member, the screw cap having a screw-threaded edge portion which surrounds the air-intake valve and engages a complementary screw-threaded portion at said other end of the container. ### Claim 19 (depends on 12) An implement according to claim 12, wherein the container tapers from said other end towards said one end.
