Abstract
A liquid applicator implement includes a container for freely movable liquid (6), a capillary storage means (16) for temporarily receiving liquid upon a change in air pressure and/or temperature of the environment, an applicator element (12) and a capillary air inlet for compensation in respect of liquid taken from the container. A passage (20) for conveying the liquid entirely or partially bridges over the distance between the container with the liquid (6) and the applicator element (12). The passage is not directly in communication with the storage means (16) and it is of lower capillarity than the storage means (16).
Claims21
An implement for applying liquid to a support, comprising:
- a container defining an interior surface, the container being separated into a first storage area for storing fluid and a second storage area with an opening therebetween;
- a tip;
- a capillary wick having a longitudinal axis, the capillary wick completely filling the opening and extending from the opening through at least a portion of the second storage area to the tip, wherein the capillary wick has a passage along at least a portion of the longitudinal axis of the capillary wick, wherein the capillary wick has an average capillary;
- and
- a capillary storage associated with the second storage area and separated from the first storage area such that the capillary storage only comes into contact with fluid from the first storage area by way of the capillary wick, wherein the capillary storage has an average capillary;
- wherein the average capillary of the capillary storage is less than the average capillary of the capillary wick, and the passage has a lower capillary than the average capillary of the capillary storage;
- wherein within the capillary wick is a capillary air inlet to allow air to enter thereof for compensation of liquid taken from the first storage area of the container.
