Abstract

A liquid dispenser for attachment to or forming part of a liquid container including a bore and a plug portion of substantially the same cross-section as the bore mounted in and across the bore so that the outer surface of the plug and the inner surface of the bore are in sealing contact, the outer surface of the plug portion or the inner surface of said bore including a protrusion whereby the plug or brush holder are distorted to provide a liquid channel for control of the flow of the liquid between the outer surface of the plug and the inner surface of the bore.

Claims

1. In a liquid dispenser of flexible material for dispensing liquid from a container comprising a brush holder member having an inner surface defining a bore and a plug member mounted in the bore and having an outer surface, substantial portions of the inner and outer surfaces having circular cross-sections of the same diameter and being maintained in sealing contact with each other, the improvement comprising:

protrusion means extending substantially axially on one of the inner and outer surfaces for radially distorting circular cross-sectional portions of at least one of the inner and outer surfaces to interrupt the circular cross-sections thereof to form passage means therebetween for communicating the liquid therethrough.

2. The liquid dispenser of claim 1 wherein at least one of the plug member and the brush holder member is composed of a plastic material.

3. The liquid dispenser of claim 1 wherein the protrusion means comprises a single protrusion extending at least substantially parallel relative to a longitudinal axis of the bore.

4. The liquid dispenser of claim 1 wherein the protrusion means is on the outer surface of the plug member.

5. The liquid dispenser of claim 1 wherein the protrusion means is on the inner surface of the brush holder member.

6. The liquid dispenser of claim 1 wherein portions of the outer surface of the plug member adjacent the protrusion means are distorted to provide the passage means.

7. The liquid dispenser of claim 1 wherein portions of an outer surface of the brush holder adjacent the protrusion means are distorted to provide the passage means.

8. The liquid dispenser of claim 1 wherein portions of each of the inner surface of the brush holder member and the outer surface of the plug member adjacent the protrusion are distorted to provide the passage means.

9. The liquid dispenser of claim 1 wherein the passage means comprises a pair of circumferentially-spaced passages having the protrusion means disposed therebetween.
