Description
BACKGROUND OF THE INVENTION
This invention generally relates to an applicator device, and more
particularly relates to an improved construction for an applicator
device of the type for use with dispensers, such as toothpaste
tubes or the like, and which is particularly suited for use as a
disposable fountain toothbrush.
Heretofore, various arrangements have been employed to provide
devices for dispensing fluid materials, such as dentifrices and the
like. Such arrangements have included devices wherein the
toothpaste tube, for example, was of a special design and/or made
integral with some type of toothbrush for dispensing the
dentifrice. Such prior devices, however, limited the flexibility
for use of the device by reason of the particular design of the
toothpaste tube or were not susceptible to being readily of the
throw-away type due to the integral construction of the toothpaste
tube with the brush, for example. In addition, such prior devices
were not only cumbersome and space-consuming to store, but were
oftentimes difficult to operate by reason of clogging of the
dentifrice and the practical inability to clean the same without
damage to the component parts and/or the dentifrice material. Other
arrangements have included complex multi-part devices for
dispensing, such as squeezing, pressing, etc., the tube in order to
discharge the dentifrice material therefrom. Such devices, however,
are generally intended for relatively lasting and permanent use and
hence, are generally not disposable, compact, inexpensive to
produce, easy to transport and store, or convenient to use.
SUMMARY OF THE INVENTION
An applicator device for use with a toothpaste dispenser or the
like comprising an elongated body having a forward end and a
rearward end, said body including a bristle portion adjacent said
forward end and adapted to be detachably connected adjacent its
rearward end to said dispenser, and said body having a passageway
terminating inwardly of said forward end and communicating with
said bristle portion and opening onto the rearward end adapted for
transmitting fluid material delivered from said dispenser to said
bristle portion. The body includes a plural orifice means having a
baffle-like construction disposed in said passageway adapted to
selectively control the distribution of fluid material into said
bristle portion. The baffle construction is arranged so as to
uniformly distribute the fluid material throughout the bristle
portion. A closure means is adapted to be detachably mounted over
the bristle portion to provide a protective cover therefor in the
installed position thereof.
From the foregoing description and following specification
including the accompanying drawings, it will be seen that the
present invention provides a novel and improved construction for an
applicator device for use with a toothpaste dispenser which is of
an inexpensive, throw-away construction for repeated use. The
applicator device is of a simple, yet rugged construction which can
be employed efficiently with practically any type and/or size of
toothpaste tube. Accordingly, the device has great flexibility and
lends itself to use for household and commercial application. The
device is of a compact construction made from a minimum number of
parts which can be economically produced, and which can be quickly
and easily assembled with a minimum time and effort. Furthermore,
the device by reason of its construction and arrangement, can be
readily produced and sold separately as a unit and/or sold as a
package along with the toothpaste dispenser, as desired. Still
further, the device is constructed and arranged so as to provide
optimum flow conditions for distributing the dentifrice material
uniformly throughout the bristle area of the brush so as to afford
maximum cleansing application. In addition, the device effectively
prevents clogging by the dentifrice material of the essential parts
thereof and includes a cap-like closure which is readily detachably
mounted over the bristle area to prevent contamination in the
stored condition thereof. Other advantages of the invention will be
apparent as the description proceeds with reference to the
accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring again to the drawings, and particularly to FIG. 1
thereof, there is illustrated the applicator device, designated
generally at 2, of the invention for detachable connection to a
dispenser 4, such as a toothpaste tube or the like. The applicator
device 2 is preferably of a unitary, one-piece construction which,
in the embodiment shown, may have a detachable closure member 6
mounted thereon. The device 2 may be made from suitable materials
which preferably include polymeric materials which can be
economically formed by conventional molding techniques, as known in
the art, so that the device may be disposed of or thrown away after
each use thereof, as desired.
In the embodiment shown, the applicator device 2 includes an
elongated body 8 having a rearward end adjacent the dispenser 4 and
a forward end remote from the dispenser. Preferably, a major
portion of the body is tapered in a convergent direction away from
the rearward end in a generally cylindrical construction and then
levels out into a generally planar, polygonal construction to
provide a support surface for the bristles, as will hereinafter be
more fully described.
The body 8 includes an elongated passageway 10 which tapers
convergently in a direction from the rearward end toward the
forward end and then makes a generally right-angle bend as at 12 so
as to open onto the upper surface of the body to provide a fluid
transmitting passageway for communicating the dispenser 4 with the
bristles. Accordingly, the passageway opens into a generally
circular aperture or opening 14 (FIG. 2) which is disposed
generally centrally within a support section 16 which mounts the
bristles. Preferably, the passageway 10 is tapered throughout a
major length of the body 8, but is then of a generally cylindrical
linearly extending construction within the support section 16
wherein it is of a generally uniform diameter until it forms the
bend 12 and hence, the opening 14 which is preferably of a greater
diameter than that of the linearly extending portion of the
passageway which is disposed in the support section 16, as seen in
FIG. 3. By this arrangement, there is provided a good runner system
for transmitting fluid materials, such as dentifrices or the like
from the dispenser 4 through the applicator body 8 and out through
the orifice opening 14.
In the embodiment shown, the orifice opening 14 is provided with a
baffle construction for distributing fluid material uniformly
throughout the bristles. The baffle construction includes a baffle
member 18 which extends transversely in bridging relation across
the opening 14. The bridging member 18 provides a bifurcated
construction for the opening 14 and acts as a divider or partition
to divide the opening into a smaller hole 20 and a larger hole 22.
By this arrangement, a greater amount of fluid material may be
emitted through the hole 22 so as to be distributed upwardly and
generally forwardly throughout the bristles while the smaller hole
20 enables a reduced amount of material to be so distributed,
thereby to insure a generally uniform distribution throughout the
bristles. In the form shown, the baffle member 18 is preferably of
a polygonal, such as triangular construction, which has a generally
upper flat surface 24 disposed in the general plane of the support
member 16 and a pair of inclined side surfaces 26 and 28 (FIG. 3)
which extend convergently toward one another in a direction away
from the upper surface 24. Preferably, the side surface 26 is
disposed at a greater angular inclination with respect to the
longitudinal central axis of the body 8 as compared to the
forwardly disposed side surface 28. By this arrangement, the
surfaces 26 and 28 act as deflectors for selectively controlling
the distribution of fluid material through the respective openings
20 and 22 with the inclination of the side surface 28 being
disposed so as to deflect a greater portion of the fluid material
upwardly and forwardly throughout the bristles as compared to the
amount deflected by the surface 26. As best seen in FIG. 2, the
support section 16 is provided with a series of rows of oppositely
disposed, generally parallel extending bristles 32, 34 and 36 with
the intermediate row 34, for example, being foreshortened relative
to the rows 32 and 36 so as to accommodate therebetween the orifice
opening 14. Accordingly, in the invention either by varying the
size and/or shape of the openings 20 and 22, and/or by varying the
inclination of the surfaces 26 and 28 of the baffle member 18, the
amount and direction of fluid material delivered from the dispenser
4 can be selectively controlled to obtain a uniform distribution
throughout the bristles.
As best seen in FIG. 1, the body 8 is preferably provided with an
integral coupling member 40 which is of a generally cap-like
construction which is internally threaded for threaded attachment
to a corresponding neck portion provided on the dispenser 4, as
known in the art. Accordingly, the coupling member 40 is of a
generally hollow construction and communicates in fluid
distributing relationship with the passageway 10 provided in the
body 8 for the purposes, as aforesaid.
In the invention, the device 2 is preferably provided with a
detachable closure member 56 which is of a elongated, cylindrical
cup-like configuration defined by an endless cylindrical side wall
52 which is closed at one end by a top wall 54. The member 56 is
provided at its other end with a flexible sealing member 56
comprised of an elastomeric material, such as rubber or the like.
The sealing member 56 is provided with a cut-out opening 58 which
is shaped so as to correspond to the transverse cross-sectional
shape of the body 8. Preferably, the opening 58 is of a peripheral
dimension less than that of the outer peripheral shape of the body
8 so as to provide a tight fluid seal around the body to prevent
the ingress of deleterious materials onto the bristles.
In FIG. 4, there is illustrated another modified form of the
closure means for the applicator device 2 of the invention. In this
form, the means includes a closure member 60 which is also of a
cap-like construction. In this form, however, the member 60 is of a
generally U-shaped construction defined by an endless side wall 62
which is closed at one end by an integral top 64. The member 60 has
an open end remote from the top 64 which has a periphery generally
corresponding to that of the support section 16 so as to be
supported in generally nested relation thereon. As shown, the
member 60 includes two pair of oppositely disposed recesses 66
adapted for interlocking snap-acting coaction with projections or
protuberances 68 which are made integral with and which project
outwardly from the support section 16. Accordingly, by this
arrangement, the closure member 60 may be disposed over the
bristles and conveniently snapped into place for securement on the
support member 16 to provide a protective cover for the bristles
for the purposes, as aforesaid. In the invention, the closure
members 56 and 60 are preferably made from a light weight polymeric
material which is preferably transparent to facilitate visual
observation of the condition of the bristles, as desired.
