Description

FIELD OF INVENTION

The present invention relates to a cleaning brush, and more particularly, the present invention relates to a cleaning brush for hard-to-reach areas.

BACKGROUND

Bottle-cleaning brushes are well-known in the art of cleaning bottles. These brushes are often used to clean containers and the like. Available in varied sizes, the bottle-cleaning brushes can be inserted into long containers for providing abrasive cleaning action. The bottle cleaning brushes can be made from bristles interlocked into a twisted hard wire. The bristles are made from plastic materials while the wire can be made from metal. The twisted wire is rigid but can flex under force. Part of the brush can bend to reach difficult-to-reach areas. However, the known bottle-cleaning brushes are suitable for cleaning plain bottles only. Containers and articles of complex design, such as hookah are hard to clean with bottle brushes. For example, the hookah has a very narrow opening and a broad bottom. The stem or the neck of the hookah is long and narrow.

A need is therefore appreciated for a cleaning brush that overcomes the limitations of conventional bottle cleaning brushes.

Disclosed is a cleaning brush that because of its unique design and structure, can clean hard-to-reach areas. The disclosed cleaning brush can easily insert through narrow sections of the container without undesired force. The disclosed cleaning brush can easily clean complex design containers, such as those having a broad bottom and a narrow neck. An example of such a container is a hookah that has a wide round bottom container and a long narrow neck/stem. The disclosed cleaning brush can efficiently clean the wide bottom container by providing a flexible cleaning head with a larger cleaning area.

Referring to FIG. 1 is a perspective view of the disclosed cleaning brush. For understanding, the cleaning brush can be divided into three sections, an upper portion 110, a middle portion 120, and a lower portion 130. The cleaning brush 100 can be made from a long-twisted wire 105 of material, such as metal. Two or more wires can be twisted to form a braid. The bristles can be interlocked into the twisted wires. Such twisted wires are known to be used in bottle-cleaning brushes. However, the disclosed cleaning brush can have a long and strong twisted wire that can be used with long containers and articles, such as a hookah. The twisted wire can be rigid enough to prevent bending while cleaning. However, the twisted wire can bend without any recoil when force is applied. The twisted wire can although be flexible so that it can flex a little while applying force during cleaning. Bristles can be disposed along the length of the twisted wire that can be used for cleaning by providing an abrasive action. The bristles can be disposed in intervals. Moreover, the type of bristles can be varied along the length of the cleaning brush. Variations can be in the size of the bristles and the hardness of the bristles. For example, the bristles in the topmost portion of the cleaning brush can be small in size, wherein the top end of the cleaning brush can be used for cleaning narrow containers and passages. The middle portion of the cleaning brush can be provided with medium size bristles that can be suitable for cleaning most surfaces.

The top portion 110 of the cleaning brush 100 can act as a handle to hold the cleaning brush while cleaning. The proximal end portion 140 of the twisted wire can be provided with bristles so that the top portion can also be used for cleaning the narrow openings and passages. The top portion of the twisted wire can be bent as shown in FIG. 2 to hold the cleaning brush and rotate the same with the hand for cleaning. The bent top portion, as shown in FIG. 2, may provide a comfortable grip to hold the cleaning brush. The twisted wire portion between the topmost bristle portion 140 and the mid portion 120 can be provided with a grip 160, such as a silicon sleeve. The grip may make holding the cleaning brush more comfortable and ergonomic. The silicon sleeve can also protect the twisted wire from dirt, grease, and the like contaminants. Also, the silicon sleeve may prevent forming acute bends in the twisted wire which may damage it. Also, the silicon sleeve may prevent direct contact with the twisted wire to the rim of the container, which may otherwise scratch or damage the container being cleaned.

The elongated middle portion 120 can have bristles throughout, whereas the size and hardness of these bristles can be suitable for cleaning most surfaces and containers. For narrow stem containers, the mid portion can provide cleaning of the long narrow stem while the bottom portion of the cleaning brush can clean the bottom of the container.

The bottom portion 130 of the cleaning brush may have a cleaning head 150 that can be used to clean broad containers. The portion of the twisted wire between the middle portion 120 and the cleaning head 150 can be plain without any bristles. This portion can be bent under force to provide the cleaning head with a desired angle for cleaning. As shown in the drawing, the cleaning head 150 is at the distal end of the twisted wire and the plain twisted wire portion 135 is near the distal end. The cleaning brush can also be bent around the middle portion 120, while holding the handle portion 110 and the plain twisted wire portion 135, wherein the middle portion 120 forms a loop for cleaning. The top portion and the bottom portion can be grasped together, and the looped middle portion can clean a surface.

The distal portion 130 of the cleaning brush 100 having the plain twisted wire portion 135 can also be provided with a sleeve (more clearly shown in FIG. 3), such as the silicon sleeve. FIG. 3 shows the cleaning brush without bristles. One sleeve 160 is shown near the proximal end of the twisted wire and another sleeve 170 is shown near the distal end of the twisted wire. The silicon sleeves, as described above, may prevent the deposition of contaminants on the twisted wire and provide a soft grip. Also, the sleeves may prevent direct contact with the twisted wire.

FIG. 4 shows an enlarged view of the distal portion 130 of the cleaning portion. As shown, the distal end of the twisted wire is coupled to the cleaning head 150. FIG. 5 is an exploded view thereof showing the twisted wire 105, the silicon sleeve 170, a crimp 220, a plate 200, and a second twisted wire 210. FIG. 6A shows the top view of the plate 200, FIG. 6B shows a side view of the plate 200, and FIG. 6C shows a front view of the plate 200. The plate 200 has a proximal end and a distal end. Two holes 230 in proximity to each other are in the central portion of the plate 200. The distal end of the twisted wire 105 can loop through these two holes 230 for securing the cleaning head 150 to the twisted wire (shown in FIG. 4). The plate 200 can flex sidewards relative to the length of the twisted wire.

The plate 200 can have cutouts 250 at its two ends wherein the second twisted wire 210 can be secured to these cutouts 250. The second twisted wire 210 has loops 260 at its two ends, wherein the two loops can be secured to the two cutouts 250 while the second twisted wire passes across the bottom of the plate. To further stabilize the second twisted wire, an end of the twisted wire can be made to insert into an offset hole 240 in plate 200. The second twisted wire can also be provided with bristles, wherein the cleaning head being flexible can easily clean wide and contoured containers, such as bowls.

FIGS. 7-10 shows steps in the insertion of the disclosed cleaning brush 100 into container 10 with wide and rounded bottom and a long narrow neck. The cleaning head can flex sidewards to substantially align with the twisted wire, as shown in FIG. 7. This configuration of the cleaning head allows the distal portion of the cleaning brush to easily pass through the narrow opening. FIG. 8 shows the cleaning brush further inserted into the container. FIG. 9 shows the cleaning head touching bottom of the container while the middle portion is within the narrow neck. FIG. 10 shows the cleaning head pushed over the bottom of the container and the middle portion in contact with the neck of the container. The brush can now be agitated and moved within the container to clean the complete container at once. The cleaning head can flex while cleaning the wall of the container, thus efficiently cleaning the complex curves of the container.

The disclosed cleaning brush can be used to clean the hookah including the container and stem of the hookah. FIG. 11 shows the cleaning brush positioned inside a typical hookah; wherein different sections of the inner hookah come in contact with the bristles of the cleaning brush. The cleaning brush can be used at both ends, i.e., at the cleaning head or the handle portion to effect abrasive cleaning action.

As shown in FIGS. 4 and 5, the two holes through which the twisted wire passes are not at the center of the plate but are offset to the center. The portion of the plate left to the twisted wire joint is longer than the opposite right side portion of the plate. This is a critical feature of the invention and allows the cleaning head to be withdrawn from the container. The longer left side, upon lifting the cleaning head, first touches the wall of the container which causes the short right side to rise towards the twisted wire, and the cleaning brush in this configuration can be pulled out through the narrow stem of the container. Also, the right side of the plate has a bent portion 280 for balancing the position of the plate against the twisted wire.

In one case, the twisted wire can be about 20 inches in length. The small bristle portion at the proximal end of the cleaning brush can be about 0.5 inches followed by 4 inches of exposed twisted wire having the sleeve. The middle portion can be about 10 inches followed by about 5.5 inches of exposed twisted wire.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
