PROBLEM TO BE SOLVED: To secure the sealing performance of an attaching part between a cleaning container and a dispensing head, to facilitate attachment and detachment, and to safely discharge a residual gas to the outside during the detachment.SOLUTION: In a dispenser cleaning container provided with an attaching body 3 attached to a mouth 10 of a container body 1 storing a cleaning liquid W via a seal member 5 and detachably attaching a dispensing head 2, the attaching body includes a cylindrical attaching part 33 having a female thread 32 screwed with a male thread 11 provided at the mouth. The seal member is formed of a synthetic rubber member integrally forming first and second seal pieces 51, 52 fitted into a circumferential groove 34 formed at a cylindrical attaching part by means of a protrusion and capable of brought into contact with an inner circumferential surface 10a of the mouth and an inner wall 34a of the circumferential groove. The both seal pieces are formed in a mutual opening-expanded taper shape toward tips. A taper surface 13 with an opening expanding toward an upper end for gradually releasing the contact with one seal piece when detaching the attaching body is formed on an upper part of the inner circumferential surface of the mouth. |
