Claims
We claim:
1. An applicator comprising a fluid container having a neck
provided with external threads and provided with a mouth forming a
shoulder, a fitting disposed in said neck, said fitting including a
cylindrical portion force fitted in said neck and a downwardly and
inwardly extending resilient truncated conical portion, a cap
threadedly removable disposed on said neck, a downwardly and
inwardly tapered shank depending from said cap and extending
through said fitting, bristles on the lower end of said shank
forming a brush, said conical portion having a circular opening of
less internal diameter than the smallest diameter of said shank and
being engageable with said bristles to wipe said shank clean of
fluid while removing excess material from said brush when said cap
is moved from said container, said conical portion having four
annularly equally spaced slits therein forming a plurality of wiper
blades, said slits extending substantially only half the height of
said conical portion so that when said wiper blades are in
engagement with said shank the uppermost part of said conical
portion is additionally forced against said neck to further
clampingly hold said fitting in said neck.
Description
This invention relates to a dripless brush applicator for use in
application of correction fluid and the like.
In the past, various brush-type applicators have been provided for
applying various types of pigments, lacquers, paints, correction
fluid and the like.
These brush-type applicators employ brushes which extend into the
liquid. Usually the liquid is relatively quick drying when exposed
to air and substantial quantities of the liquid gather on the shank
of the applicator and on the brush so that not only is there the
possibility of liquid dripping in an undesirable manner, but too
much liquid is usually left on the brush for careful application,
and substantial quantities of the liquid are wasted by drying on
the shank of the brush.
The concept of this invention is to employ a fitting which is
inserted in the neck of the container and wipingly engages both the
tapered shank of the brush and the bristles to wipe all of the
liquid from the shank and excess fluid from the bristles so that an
accurate marking for obliterating errors can be obtained through
the use of this device.
Still further objects and features of this invention reside in the
provision of a dripless brush applicator which is simple in
construction, which is capable of being used with various existing
formulations of correction liquid, and like lacquers, yet which is
simple in construction and manufacture and inexpensive to produce
so as to permit wide use and distribution.
These, together with the various ancillary objects and features of
this invention, which will become apparent as the following
description proceeds, are attained by this dripless brush
applicator, a preferred embodiment of which is illustrated in the
accompanying drawing, by way of example only, wherein:
FIG. 1 is an exploded sectional view of the dripless brush
applicator constructed in accordance with the concepts of the
present invention;
FIG. 2 is a bottom plan view of the fitting looking in the
direction of line 2--2 in FIG. 1;
FIG. 3 is a vertical sectional view of the invention shown in an
assembled condition; and,
FIG. 4 is a view similar to FIG. 3, but showing the manner of
operation of the device as the cap is being removed.
With continuing reference to the accompanying drawing, wherein like
reference numerals designate similar parts throughout the various
views, reference numeral 10 generally designates a container formed
of glass or the like having a neck 12 provided with external
threads 14 thereon. The container 10 is preferably formed with a
firm base and is adapted to be filled with a correction liquid 16
or similar lacquer which is relatively quick drying. The neck 14
terminates in a mouth 18 forming a shoulder 20.
A fitting, generally indicated at 22, is provided and includes a
cylindrical portion 24 having a downwardly and inwardly tapering
truncated conical portion 26 integral therewith. Also integral with
the cylindrical portion at the top thereof is a peripheral flange
28 which is adapted to engage the shoulder 20 when the fitting 22
is force fitted in the neck. The cylindrical portion 24 clampingly
engages the inside of the neck 12. The conical portion 26 has four
annularly spaced slits 30 therein which extend substantially or a
little more than half way the height of the truncated conical
portion 26 so that when in engagement with said shank the uppermost
portion of the conical portion is forced against the neck.
A cap, generally indicated at 34, is provided which includes a
cylindrical portion 36 having internal threads 38 adapted to
readily engage the threads 14 and a top portion 40 having a
dependent cylindrical portion 42 extending downwardly therefrom.
The cap 34 further includes a shank 44 integral with or detachably
secured to the cylindrical portion 42. The shank 44 is downwardly
and inwardly tapered. Affixed to the lower end 46 of the shank 44
are a plurality of bristles 48 forming a brush.
After the fitting 22 has been force fitted in the neck 12, the cap
is inserted through the fitting 22 and threaded on the neck 12. The
shank 44 and the bristles 48 extend into the fluid 16. When it is
desired to withdraw the brush from the container, it is merely
necessary to unscrew the cap and lift the cap. The inner diameter
of the tapered conical portion is of less diameter than the
smallest diameter of the shank 44 and the bristles 48 so that it
will wipe the shank 44 entirely clean from liquid, while removing
excess fluid from the bristles so that the brush will be in a
position for effective operation and use such as marking out
typewritten characters and the like.
A latitude of modification, substitution and change is intended in
the foregoing disclosure, and in some instances, some features of
this invention may be employed without a corresponding use of other
features.
