BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a dispensing cap for a liquid container provided with an applicator means fixed thereto and for insertion into an opening of the liquid container, wherein the dispensing cap has a closable outlet opening in its outer end located opposite the applicator means, which opening is connected along a channel running through the dispensing cap to at least one feed aperture arranged in the vicinity of the applicator means.
Such a dispensing cap is known from EP-A-0 398 936. The known cap is intended for a bottle with correction fluid and is provided with a brush for placing in the neck of the bottle with which the correction fluid can be applied and spread when larger areas have to be corrected, and a pin tip with which smaller quantities of correction fluid can be dispensed.
The known dispensing cap has the drawback that, after the use of the pin tip, correction fluid can remain behind in the channel which, when the brush is subsequently used, can then run out along the handle thereof whereby an unintentionally large amount of correction fluid is spread onto the error for correcting. There is therefore the danger of for instance a part of a text round an error also being smeared with correction fluid. In addition, an excess dose of correction fluid results in a comparatively long drying time, while in this manner the content of the bottle is also consumed too quickly.
SUMMARY OF THE INVENTION
The invention therefore has for its object to provide an improved dispensing cap of the above described type wherein these drawbacks do not occur. This is achieved according to the invention by a closing member co-acting with the feed aperture. Due to such a closing member unused liquid is retained in the channel between the feed aperture and the outlet opening and can therefore not leak out.
Preferred embodiments of the cap according to the invention are described in the dependent claims.
The invention also relates to a liquid container provided with a dispensing cap as described above.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is elucidated with reference to the annexed drawings in which:
FIG. 1 shows a longitudinal section of a dispensing cap according to the invention arranged on a liquid container in its rest position,
FIG. 2 shows a section corresponding with FIG. 1 of the liquid container with dispensing cap during use, and
FIG. 3 is a section corresponding with FIG. 1 and 2 of the dispensing cap per se.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
A dispensing cap 1 (FIG. 1) is provided with an internal screw thread 2 with which it can be screwed onto a neck 4 of a container 5 likewise provided with screw thread 3. An applicator means 6, in the example shown a brush, is fixed in the dispensing cap 1. With brush 6 a liquid arranged in container 5, for instance correction fluid, can be applied in dosed manner to a surface such as a sheet of paper which has been written on. A comparatively large amount of liquid is herein dispensed.
In order to also enable dispensing of more finely spread liquid the dispensing cap 1 is provided on its outer end 7 located opposite brush 6 with an outlet opening 8 which is closable by means of a needle valve 9. This needle valve 9 is movable in the outlet opening 8 and is biased by a pressure spring 22 connected to cap 1 to a rest position closing the opening 8. Valve 9 is pressed inward counter to the biasing force of spring 22 and thus leaves the opening 8 clear when it is pressed onto a surface (FIG. 2). The outlet opening 8 is connected via a channel 10 running through dispensing cap 1 to a plurality of radially directed feed apertures 11 which are arranged round the upper part of the brush 6 and which communicate with the interior of liquid container 5.
In order to prevent liquid which may have collected in channel 10 from leaking out through apertures 11 during the use of brush 6, the dispensing cap 1 according to the invention is provided with a closing member, in the example shown a ball 12. The ball 12 is movable in
