ENHANCED CLEANING EFFECTS

FIELD OF THE INVENTION The present invention relates to an improved cleaning brush having an elongated handle and a head protruding from the handle on the opposite side of the handle and having a longitudinal geometric axis, the end of which has one end of flexible bristle bundles. The special bristle brushing of the toothbrush is particularly suitable for penetrating the front side of the toothbrush and exerting an increased cleansing effect, with an enhanced surface cleansing effect.

In general, the purpose of toothbrushes is to clean the surface of the teeth, to remove deposits and food debris from the surface of the teeth, including curved tooth surfaces and tooth teeth, i.e. the entire tooth surface. For such complete cleaning, conventional toothbrushes are generally provided with bristles of equal length bristle bundles, the ends of the bristle bundles being cut straight and the other end fastened to the toothbrush head. However, the cleaning ability of such a generally flat surface bristle is limited, as it does not fit into the teeth and cannot penetrate into the teeth to remove deposits and food debris from there, especially because the bristle bundles with the flat contact surface collide with each other.

The user with such a flat surface bristle brushing the teeth under strong pressure and attempts to deform the bristle according to the above purpose in order to follow the curvature of the teeth and at least partially penetrate the bristles. However, such a rough use, on the one hand, causes significant damage to the tooth surfaces and gums and, on the other hand, is not really suitable for providing the desired cleaning effect.

U.S. Pat. No. 5,742,972 discloses a toothbrush having a bristle bracket designed to be the longest at the furthest portion of the bristles and gradually decreasing

97974-5894A Er / Dm • · · · · · · · · · · · · · · · · · · · · · ·

-2levágva. At the end of the head towards the handle, the bristle bundles are also the longest at the end of the bristle and at a lower height toward the middle. Thus, the bristle is slit-like along the longitudinal axis of the head section. This design meant that the bristles were better aligned with the teeth surface and the teeth in the intervertebral and tibial areas.

Although this combination of shapes aligned the bristles with the design of the teeth, as with conventional flat bristles, it still did not provide the proper bristle arrangement and shape to allow effective cleaning of the teeth.

Various other brewery designs are described in U.S. Patent Nos. 5,335,389, 5,341,537, 5,446,940, and 5,459,899. These bristles show combinations of different longer and shorter bristle bundles that are generally perpendicular to the plane of the toothbrushes, but also include angled bristle bundles formed from individual bundles and / or bristle blocks.

The bristle pattern disclosed in U.S. Patent No. 5,742,972 is more consistent with the shape of the tooth and the teeth than the conventional flat design, but, as in the case of the solution described in U.S. Patent No. 5,742,972, the arrangement and design of the bristle bundles does not provide a proper fit for the teeth. the cleaning surface is not intensive enough.

U.S. Pat. No. 422,143 and U.S. Pat. No. 425,306 show a bristle arrangement in which the bristle bundles are flat in themselves, but three spaced bristle blocks are formed in a direction perpendicular to the longitudinal axis of the toothbrush at the ends of the toothbrush head. Since the conventional toothbrush head sections are generally about 30 mm long, such a three-bristle block has a length of only about 20 mm to accommodate the bristle bundles, i.e. the distance between the bristle blocks can be up to 10 mm. Considering that the size of the adult tooth may be 10 mm or more, the distance of up to 10 mm between the bristle blocks, as described by the reference pattern, does not allow the bristle blocks to penetrate into the gaps between the teeth.

• · · · · ··· «· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

-3In addition, the three bristle blocks in the described arrangement, positioned perpendicular to the longitudinal axis of the head section, have the result that at least one of the bristle blocks strikes a surface of a small front teeth and thus prevents other bristle blocks from penetrating and exerting a cleaning effect on the teeth. In the absence of the introduction of the bristle blocks by the light movement into the intervertebral parts, the user tries to introduce the bristle blocks again with intense pressure between the incisors, canines, grinding teeth and the teeth, causing the harmful effect described above.

Therefore, there is a clear need for a toothbrush design in which the bristle bundles are designed to penetrate easily into the teeth and better fit the toothpicks to provide more effective cleaning in conventional solutions without the need for intensive and harmful rubbing.

The object is accomplished by a toothbrush having an elongated shaft and a head extending from the handle end extending at the tip opposite to the shaft, having a longitudinal geometric axis, the end of which has one end of flexible bristle bundles, the head being transverse to the geometric axis two, a bristle bundle extending at least 10 mm from the front panel divides the bristle bundle portions, the first bristle bundle being located at the apex and a radius of curvature concave with radius R1, the second bristle bundle being located between the two transverse bristle bundles and the radius R2 the front bristle has a concave envelope, the third bristle bundle is located on the handle and has a concave envelope with radius R3, seen from the handle.

In another embodiment, the first bristle bundle portion is a casing curve sloping from the tip to the center of the head portion of the second bristle bundle located between the transverse bristle bundle rows, the V-shaped envelope facing the center of the head, and the third bristle bundle being the head portion. It has a sloping envelope toward the middle of it.

In a third preferred embodiment, the first bristle bundle portion has a concave envelope facing from the tip, the second bristle bundle portion having a radius of curvature concave with a radius R2 and consisting of a bristle bundle group 4, some of which are centered toward the tip or toward the handle. and another portion of them is inclined at the edges of the head in opposite directions to the adjacent groups. The third portion of the bristle bundle has a radius of curvature concave with respect to the shank R3.

Preferably, the first bristle bundle portion and the third bristle bundle portion comprise at least two bristle bundles, each transverse to the geometric axis, and the radii R1 and R3 of the sheaths are 150 to 200 mm in length.

The two transverse bristle bundles can form beer bars with a diameter of about 0.8 mm and a length of at least 50 mm.

The diameter of the bristle bundles is generally at least 0.25 mm.

The bristle bracket according to the first embodiment fits well to the curvature of the teeth while at the same time being able to penetrate easily into the teeth and provides a better cleaning and deposition removal effect on both the tooth surfaces and the tooth surfaces.

The pattern according to the second embodiment further removes the space between the bristle bundles, thereby providing an enhanced cleaning effect, especially on the tooth surfaces.

The pattern of the third embodiment also easily penetrates into the teeth, especially when moving the toothbrush in a horizontal direction forward and backward.

Further details of the invention are illustrated by way of example in the drawing. It is in the drawing

Fig. 4 is a side view of the third embodiment, wherein the drawing does not include a handle representation and

Fig. 5 is a top view of the embodiment shown in Fig. 4.

-5Αζ The embodiment shown in Fig. 1 is a toothbrush 10 having an elongated mandrel 12 and an elongated head portion 14 on which two transverse bristle bundles 24 and 26 are disposed in a bristle arrangement along the longitudinal axis AA. The length of the two bristle bundles 24, 26 is at least equal to the length of the other bristle bundles of the bristle, which means that they are at least 10 mm, preferably at least 12 mm long, measured from the front face 22 of the toothbrush. These bristle bundles 24, 26 may be formed from individual bristle bundles, but may also be provided as a continuous bristle block. Their distance between each other is at least 12 mm, preferably at least 13 mm, particularly preferably at least 15 mm, and is located on the front face 22 of the toothbrush 10 to divide the head 14 into three different bristle bundles 16, 18 and 20. The free ends of the bristle bundle portions 16, 18 and 20 in each of the three segments are cut into a profiled casing, such that, from the front face 22 of the head 14, the envelopes are concave.

The profiles thus formed provide enhanced cleaning performance as each bristle tufts do not stick together and, at the same time, better fit the curves of the tooth surfaces or the teeth. This brewery combination, where the bristle bristle is divided into two portions with two transverse bristle bands 24, 26, and the portions are cut into shape, allows easy penetration of the bristles into the teeth, without preventing the penetration of another bristle or bristle bundle and providing the bristles. the enhanced cleaning effect of the present invention.

Figures 2 and 3 show well the bristle bundle portions 16 and 20, which consist of at least two generally parallel bristle bundles. The number of rows can be more than two, and their arrangement is transverse to the longitudinal axis AA of the head 14. It can be seen from above that the bristle bundle portion 18 also consists of substantially parallel bristle bundles, which are also perpendicular to the longitudinal axis AA of the head 14, as shown, for example, in Figure 5. However, the solution shown in Figure 3 may also be formed, wherein the bristle bundle portion 18 consists of bristle bundles arranged along substantially concentric circles. In addition, the second portion of the bristle bundle 18 may be formed in other geometric shapes, such as hexagons, octagons, or other forms. Regardless of the form in which the bristle bundles are arranged in a top view, each ·· · ·

In the case of the second envelope shown in Figures 2a or 4.

Figure 2 shows that the free end of the first bristle bundle portion 16 is formed in a downward curved shape near the tip of the toothbrush 10, i.e., in the side view, or the profile, the free ends are arranged along a circle of radius R1. This arc is concave when viewed from the tip of the toothbrush 10. Similarly, the free ends of the third bristle bundle portion 20 will be shortened at a portion close to the toothbrush 12 of the toothbrush 10, and there will also be a concave envelope that is concave with the radius R3 from the handle. This R3 radius may be the same as the radius R1, but may be different. Preferably, both R 1 and R 3 are about 150-200 mm long, preferably 160-190 mm.

It is also apparent from Figure 2 that the free ends of the second bristle bundle portion 18, which are disposed between the transverse bristle strips 24 and 26, are cut along a radius R2. This envelope of radius R2 is concave viewed from the front face 22 of the head portion 14 of the toothbrush. The preferred length of R2 is 90-150 mm, preferably 110-140 mm.

The toothbrush lines of the present invention are preferably flexible to easily fit into the tooth curve and tooth teeth. Such flexible bristles are generally 10 mm high from the front panel 22 and are preferably circular in diameter, preferably at least 0.254 to 1.27 mm in diameter. This basically means that their cross-sections are from 0.00645 to 0.03871 cm 2 .

The bristle blocks 24 and 26 are different from the bristle bundle since the bristle bundles are formed from bristle groups, i.e. bundles, as described above, while the bristle blocks are shapes formed by individual bristles formed by individual bristles, acting as a single array at a glance, where the array is at least 5 longitudinally at least 5 mm, preferably at least 8 mm, and transversely at least 8 mm, preferably at least 10 mm.

In addition to being flexible in the bristles, it is advantageous to have a softness to form the arrangement according to the invention, thereby also ensuring cleaning and removal of food residue along the gum, without the · · · · ·.

Would cause irritation or bleeding. Preferably, the ends of the bristles are rounded and have a diameter of 0.0762-0.3048 mm, preferably 0.127-0.02032 mm.

Another preferred embodiment of the toothbrush of the present invention is shown in Figure 2a. Here, as previously mentioned, the length of the bristles on the first and third bristle bundle portions 16 and 20 decreases toward the center of the head portion 14 and is cut off in a lateral plane with an inclined plane. The middle portion of the third bristle bundle 18 is delimited in side view by two also oblique planes which are bent downwardly in the V-shape from the center 36 of the head 14, i.e. in two directions from the BB plane shown in Figure 2. The inclination of the oblique planes is reduced by about 20%, i.e. two units along ten length units.

Figures 4 and 5 show a third embodiment of a toothbrush according to the invention. Here, the side view of the bristle bracket is substantially the same as the side view of the first embodiment shown in Figure 2, the difference being that the middle bristle bundle 18 partially comprises the inner bristle bristles 28, which are separated by outer bristle bundles 34 from the flange 32 of the toothbrush head 14 on both sides. A portion of the inner bristle bristles 28 is inclined at an acute angle with respect to the front face 22 of the head section 14, or toward or opposite the tip 30. At the same time, the outer bristle bristles 34 are positioned at the same or different angles in the opposite direction, i.e. in the opposite direction to, or inclined to, the tip 30, i.e. always in the opposite direction to the inner bristle bundles 28 as shown in Figure 4. The outer bristle bristles 34 and the inner bristle bristles 28 also tend to be inclined at an angle of 78 to 95 ° to the front face 22 of the head 14. This angle is preferably 80-90 °, most preferably 80-85 °.

The bristle bundle arrangement thus aligned ensures that each bristle bundle can easily penetrate into the tooth when the toothbrush is moved horizontally between the front and rear teeth during brushing.

The rows of the toothbrush of the present invention may be made of any conventional bristle material. Usually it is appropriate to use nylon and polyester materials, of which nylon is recommended. DuPont de has proved to be beneficial

Nemours and Company (Wilmington, Delaware) nylon material 6.12, marketed under the TYNEX® brand.

-8A bristle bundles can be fixed to the front face 22 of the head section 14 of the toothbrush 10 using conventional stacking technology, but more modern, non-bundling technologies such as US 4,635,313, US 4,637,660, US 4,954,305, US 5,045,267, US 5,390,984, US can be used.

5,533,791, U.S. Patent Nos. 5,609,890 and 5,823,633.

When using such techniques, the bristle bundles are melted into the front face 22 of the head section 14 by softening or melting the bristle bundles and the head 14, or the bristles are embedded in the toothbrush molded tool, such that when the toothbrush material flows into the tool and the toothbrush is finished, the bristle bundles are already embedded in the tool.
