FREILING ATTORNEYS 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.

FIG. 4 is a fragmentary, generally perspective view illustrating a modified form of the cap-like closure which can be employed with the applicator device of the present invention.
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 rightangle 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 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 I 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 transparentto facilitate visual observation of the condition of the bristles, as desired.
