Brush device for dispensing liquid material by using plunger means
Brush device which dispenses fluid material such as toothpaste or paint is equipped with a dispenser and brush. The dispenser comprises a liquid material container and a plunger therein which is manually actuated to pressure out the liquid material from the container. The brush body is detachably connected to a liquid material container using a screw mate and elongated hub engagement. The material is pressured by the plunger to enter into a series of conduits incorporated into a body of the brush and, through the openings of the head of the brush, finally pushed out to the bristles of the brush. When the fluid in the container is completely used up, the dispenser is reloaded with new fluid by sliding a plunger of the dispenser.
I. Field of the Invention
The present invention relates to a brush. More specifically, the present invention relates to brush that provides fluid material such as toothpaste or paint to the bristles from a liquid container directly connected to the brush.
II. Description of the Related Art
There have been also proposed other various kinds of combination of a toothbrush and a toothpaste container. However, they are impractical in that they have complicated structure for toothbrush and thus, the use of such container increases the overall expense associated with oral hygiene. The prior proposals also do not take into account the fact that after the toothpaste has been completely consumed, it is very difficult for user to clean the toothpaste container and recharge it with a fresh supply of toothpaste. Those proposals are potentially messy during dispensing and reloading toothpaste because they are adapting a squeeze ball or thread directly contacting toothpaste. They are also unsanitary as a result of a toothpaste build-up therein and the inner components.
For example, U.S. Pat. No. 4,269,207 Konraqd et all discloses a disposable toothpaste container for use with a toothbrush. However, many disadvantages are present in this combination. For example, the container is disposal element intended for one-time usage. Since a threaded pin is extending generally axially together with paste within the chamber, it is not sanitary. Moreover, a piston threadedly connected to the pin makes its movement too slow and it cannot clean the brush after completion of toothpaste. The joint section between the container and brush stem is by screw engagement, but it is too weak and easily broken or deformed even with a normal operational pressure, especially when it is used by children users.
It is, therefore, an object of the present invention to provide an improved brush device overcoming the disadvantages of the prior arts by providing a dispenser which is more sanitary, structurally robust, easily reloaded and dispensable, and cost effective.
SUMMARY OF THE INVENTIONA novel and improved brush device for dispensing fluid material is described. In accordance with one embodiment of the invention, a brush device comprises a dispenser forming a liquid-containing container and pressing out the fluid material within the container by sliding a plunger therein, the dispenser having a external screw threaded collar and a elongated hub at and toward the opposite side of the plunger; a brush including a brush body and a bristle-carrying brush head formed integrally with the brush body; and a channel delivering the fluid material from the container to the bristles, the channel formed axially extending through the external screw threaded collar and elongated hub of the dispenser, the brush body and head, and outlet opening toward the region of the bristles formed within the brush head. The part of the channel formed in the brush body includes internal screw threads and a cylindrical conduit. Further, the internal screw threads are adapted to mate with the external screw threaded collar. Further, the cylindrical conduit substantially fits with the diameter of the elongated hub. In accordance with one embodiment of the invention, the brush is a toothbrush and the fluid material is toothpaste. In accordance with another embodiment of the invention, the brush is a paint brush and the fluid material is paint.
The features, objects, and advantages of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings in which like reference characters identify correspondingly throughout and wherein:
A toothbrush device 10 according to an embodiment of the present invention is shown in
