Description

The present invention relates to an oral care implement having various elements, which may include a cleaner for cleaning soft tissue surfaces in a user's oral cavity, elements for brushing or caring for teeth, movable cleaning elements, vibration mechanisms and / or handle gripping elements .

There are many configurations of toothbrushes that have fixed and / or movable elements for cleaning with a mechanical drive. These conventional toothbrushes are for brushing / polishing operations and typically include a head portion for brushing / grinding operations and a handle portion. The head typically has a flat or slightly curved surface to which cleaning elements are attached or to which movable carriers with a mechanical drive for cleaning elements are attached.

There are scrapers for the tongue, as a device for removing microscopic plaque that has settled in the user's language. Conventional tongue scrapers are self-contained devices designed for the special purpose of cleaning the user's tongue. These conventional devices typically include a handle and a scraper portion without the inclusion of other cleaning elements.

Users manipulate conventional toothbrushes and tongue scrapers while grabbing their handle parts. The handles are typically simple linear rods of relatively hard material, which are both uncomfortable for the user and not easy to handle. Since these devices are commonly used in wet conditions, their handles are often slippery when used.

Many people daily use several oral care products, such as toothbrushes and tongue scrapers, to perform various oral care tasks. For example, a user can use a toothbrush to brush his teeth and then use a tongue scraper to remove plaque from his tongue. The user can reuse a toothbrush to further clean his tongue. Thus, the user can switch between various oral care products during a single procedure in a humid environment.

Conventional toothbrushes have cleaning elements that recede from the hard head. Teeth and gums are intrinsically complex in shape. Due to the solid nature of the attachment of the cleaning elements to the head of the toothbrush, the orientation of the cleaning elements is not flexible, and thus, conventional toothbrushes do not provide optimal cleaning of teeth and gums. Conventional toothbrushes therefore create greater difficulty in areas of contact with teeth located at a greater distance from the head, including interdental spaces between the teeth.

The present invention relates to an oral care product that provides several advantages and which can be used to perform many functions in brushing teeth.

The following design options describe the objects of the invention in the form of various configurations of the means for caring for the oral cavity, which provide various signs and functions. Although these objects are described in the context of specific typical design options, the invention provides an oral care product that includes one or more of the features described herein. The oral care product may include a first feature described herein in one typical configuration, as well as a second feature described here in another typical configuration.

In other words, the invention contemplates mixing and conjugating features of the described construction options in various combinations in a single oral care product. The present invention, therefore, allows you to choose a combination of configurations of the cleaning element, the configurations of the fabric cleaner, signs of the handle, signs of gripping, signs of mechanical drive, materials and orientations, etc. to achieve the intended results and provide additional health benefits for the oral cavity, such as improved brushing, polishing, teeth whitening, tongue cleansing, massaging gums, etc.

The term "cleaning elements" is intended to be used in a general sense and may include elements for cleaning, treating, grinding, bleaching, scraping, washing, etc. Cleaning elements may include, but are not limited to, nylon or fiber bristles, massage elements, and elastomeric fingers or walls configured with a circular cross section or with any desired shape including straight parts or sinusoidal parts. In the form of bristles, cleaning elements can be attached to a flexible membrane or web using molding technology, installing bundle blocks or sections by passing them through the corresponding holes in the flexible membrane or other mechanisms.

Various oral care products are described herein. One configuration is an oral care product having a plurality of groups of cleaning elements that are uniquely mounted on the head of an oral care product to facilitate flexible orientation of some groups relative to the teeth and gums being cleaned. For example, head groups can interact to “encompass” individual teeth, resulting in deeper penetration of cleaning / treating elements between the teeth. Such a configuration can provide effective complete cleaning, for example, by independently moving groups of cleaning elements relative to the head and to each other. This configuration and others are described below.

Figure 1-4 shows a toothbrush 610 in accordance with one embodiment of this invention. As shown here, the toothbrush 610 includes an elongated handle 612 with a head 614 connected to and extending from the handle. The head 614 is divided into many separate cleaning areas, which are spaced from each other. As shown, the cleaning areas include a base 616 located on the distal end of the head 614 and retreating outward from the main body 930 (figure 4) of the head. The base 616 includes at least one and preferably a plurality of cleaning elements 618. The head 614 also includes a base or carrier 620 at the proximal end of the head 614. The cleaning elements 618 also extend outward from the base 620.

Between the cleaning areas, which include the bases 616 and 620, a pair of cocoons 622 624 is installed. Each cocoon is provided with at least one and, preferably, a plurality of cleaning elements. As described below, the cocoons 622, 624 have greater degrees of freedom than the bases 616, 620. In the preferred practice of the invention, the cocoons 622, 624 are elastic elements, as a result of which the cleaning elements of the cocoons add a range of motion beyond the range of cleaning elements 618, which are in Generally static or motionless. Since the various cleaning elements are separated from each other, for example by channels 728 that extend across the entire head 614 in the transverse direction, and due to the elastic nature of the cocoons 622 624, the cleaning elements 626 can be able to rotate 360 degrees around the vertical axis of each individual cocoon. The bending angle can be dictated by the ability of the material to bend.

Toothbrush 610 thus has a head 614 in which the front (distal end) and rear (proximal end) areas are in a relatively fixed position, and in which the cleaning / treating elements, such as the cleaning / treating elements 618, have no additional degree of movement. However, the middle part of the head 614 has two areas of cleaning elements 626 that are able to rotate 360 degrees.

As shown in FIG. 4, head 614 includes a main body 930 that supports bases and cocoons. The housing 930 and the bases 616 and 620 are preferably made of conventional hard plastics, such as, for example, polypropylene, commonly used in the manufacture of toothbrush handles and heads. However, the cocoons 622, 624 are made elastic. In the preferred practice of this invention, the elasticity of the cocoons 622, 624 is achieved by using a small-diameter rocker 932 that extends from the main toothbrush head body 930. The rocker arm 932 is connected to the underside of a thin pad or plate 934, which forms the base area to which the cleaning elements 626 are attached. The mounting method of the cleaning elements 626 on the holding plates 934 can be carried out using various cleaning elements, such as bristles and other cleaning materials, according to known methods of attachment.

The desired flexibility or resilience of the cocoons 622, 624 is enhanced by enclosing the thin rocker arms 932 in the elastic material 936 during the multiple molding process. The elastic material 936 is so resilient that the rocker arms 932 return to their original shape or initial position. This action of return creates an active movement in the opposite direction of the bend of the rocker arm, which helps to brush your teeth by creating additional cleaning strokes.

As best shown in FIGS. 1, 2, and 4, the cocoons 622, 624 include an expanded portion facing the housing 930. The carrier gaskets 934 are also expanded. Each cocoon has a central part 938 of a narrow or reduced diameter in the longitudinal direction in the middle of the length of each cocoon. Thus, each cocoon as a whole has a mushroom shape.

The beam 932 may have any suitable shape, for example, with a round, square, or any other geometric shape that provides a thin size or thin diameter for the beam to facilitate the flexibility of the beam. Elastomer 936 can be considered as a continuous layer of any suitable thickness, which covers the entire Central region of the head 614, as shown, so that both cocoons 622, 624 are embedded as part of one elastic material. A portion of the head 614, which includes cocoons 622, 624, may be formed as a separate assembly, similar to the assembly described later in relation to FIGS. 5 and 6.

Although the invention can be carried out with one base and one cocoon and can be carried out with a base having some but less degree of flexibility than a cocoon, the invention is preferably carried out so that the base is generally static or fixed. In addition, the invention is preferably carried out so that there are many such bases and many cocoons. The figures show a configuration according to the invention in which four separate cleaning areas with cocoons are applied, which are located in the central part of the head 614. The invention can be implemented in a configuration in which the cleaning elements comprise a plurality of bristles or strands on each base and each cocoon.

As shown in FIGS. 3 and 4, each base 616 and 620 and each cocoon 622 and 624 may have a generally oval outer surface. The bases and cocoons are longitudinally aligned, but are separated from each other by recesses or open areas that form channels 728. As also shown in FIG. 3, the cocoons may have a larger outer surface or bearing surface for the cleaning element than at the base.

As shown in FIG. 2, the end surfaces of the cleaning elements 618 and 626 are tapered so that the end surfaces of the cleaning elements 618 taper outward towards the center of the head 614, while the end surfaces of the cleaning elements 626 taper outward in the direction away from the center of the head 614 Thus, the highest points of each set of cleaning elements 618 and the adjacent set of cleaning elements 626 are generally facing each other for each pair of base and cocoon 616, 622 and 620, 624.

Any suitable form of cleaning elements may be used as cleaning elements 618 and 626 in the broad practice of this invention. The term "cleaning elements" is intended to be used in a general sense, as described above. The use of various cleaning materials as cleaning elements of toothbrushes can have various effects. In an attempt to provide better stain removal, a rubber-like material or elastomer can be used in combination with known bristles, or it can be used on its own to “grind / whiten" the teeth.

It should be understood that the specific cleaning elements shown are for illustrative purposes only. The invention may be practiced with various combinations of the same or different configurations of cleaning elements (such as with stapled, unfinished tufted bristles or bristles embedded in molding technology, etc.) and / or with materials of the same elements from bristles or cleaning elements (such like nylon bristles, spiral bristles, elastomeric bristles, etc.). Similarly, although FIG. 2 shows cleaning elements that are generally perpendicular to the outer surface of the head 614, some or all of the cleaning elements may be inclined at different angles with respect to the outer surface of the head 614. Thus, a combination of configurations of cleaning elements, materials and orientations to achieve certain intended results for additional oral health benefits, such as improved brushing and grinding of teeth, whitening of teeth and / or masses gums.

5-6 show another embodiment of this invention. Toothbrush 1110A has the ability to provide flexible support for bristles 1026A, 1126A in certain areas. Flexibility is ensured by performing the beam holding regions 1034A, 1134A as plates, which in combination with the legs 1038A, 1138A form mushroom-shaped cocoons. The mushroom leg 1038A, 1138A is flexible to allow the plate 1034A, 1134A, filled with bristles or cleaning elements 1026A, 1126A, to move in different directions when cleaning, as described with respect to the flexible cocoons shown in figures 1-4.

Figures 5-6 show a toothbrush 1110A and, in particular, a part 1023, 1123 of the head 1114A bearing a cleaning element or bristles. As shown in FIG. 5, the cleaning element or bristle carrier portion 1023 forms an initial assembly. This assembly is carried out by introducing cleaning elements 1026A into the mold cavity into which the plastic material is injected. When the injected material solidifies, it constantly grips the bristles or cleaning elements 1026A to form a brush or assembly 1023.

To achieve functional flexibility and proper beam retention, part of the bristle holding part or assembly 1023, which includes plates 1034A, legs 1038A and connection base 1025, preferably consists of a mixture of polypropylene and a soft thermoplastic elastomer. When a mixture of polypropylene and a thermoplastic elastomer is combined with bristles 1026A, an assembly 1023 is formed. The assembly 1023 is then filled with the material of the entire toothbrush handle 1112A and head 1114A during the second injection cycle to form the complete toothbrush 1110A shown in FIG. 6. If desired or required, the entire handle 1112A and head 1114A without assembly 1123 can be made first, and then assembly or bristle holding part 1123 can be made. Although the crimping process has been described, the assembly can also be formed using a beam forming process without termination, when, for example, the cleaning elements are fused to each other and then fixed within the plates.

It should be understood that the embodiment of FIGS. 5-6 can be configured such that all parts of the head 1114A include flexible mushroom sections without less flexible bases, such as the bases 616 and 620 shown in FIGS. 1- four. Similarly, the two-stage technique for the assembly shown in FIGS. 5-6 can be used in the design shown in FIGS. 1-4 to form two or more central cocoons as a single assembly made originally separate from the residual portion heads 1114A. A completed toothbrush may be manufactured during a second injection molding process in which an assembly having interconnected cocoons 622, 624 can be molded to a handle 612 and a head 614 of a harder material.

As indicated, FIG. 2 shows the end surfaces of the cleaning elements 618 and 626, tapered up and down or zigzag. Figures 5-6 show in an alternative embodiment a narrowing when the end surfaces form a smooth, smoothly concave shape. If desired, other shapes may be used, such as a flat shape for end surfaces, or a convex shape, as well as a zigzag shape or going up and down shown in FIG. Similarly, the ends of the cleaning elements of the embodiment shown in FIGS. 1-4, as well as in FIGS. 5-6, can have various shapes, such as zigzag, convex, concave, or flat.

Figures 7-25E show further embodiments of the invention that further show the compatibility of the various aspects, features, and functions described herein in single oral care configurations. Figures 7-25E show the configurations of oral care products that provide a dentifrice having separate groups of cleaning elements, each of which can be mounted on a fixed base or flexible cocoon, and which can provide a soft tissue cleaner in addition to a tool for brushing your teeth. The configurations may be actuated or manually actuated devices, and the handles may include signs of gripping. As such, the oral care products shown in FIGS. 7-25E generally include the objects described along with those shown in FIGS. 1-6 related to groups of cleaning elements that may include flexible cocoons. It should be understood that other features can be used along with these configurations, such as the features of a mechanical drive described in the simultaneously pending applications No. 11/122224 and No. 10/768363 (that is, the heads of the various designs described here may be vibrating heads) , and signs of brushing, discussed throughout the description.

7-9 show an oral care implement 9910, such as a toothbrush, in accordance with another embodiment of the invention. As shown here, the toothbrush 9910 includes a head 9914 and a handle 8103. The handle 8103 can be formed in accordance with US patent application No. 10/902257, filed July 30, 2004, included here as a reference material, although other configurations may be used. pens such as pen 612, 1112A shown in FIGS. 1-6. The head 9914 is generally similar to the head 614 described in connection with FIGS. 1-6, with the exception of the cleaning elements 9918 and the contour surface 9940 located on the side of the head opposite to the cleaning elements. Thus, the head 9914 as a whole includes bases 616 and 620, which respectively support the cleaning elements 9942 and 9944 in a substantially static configuration. The head 9914 also includes cocoons 622 and 624 located between the bases for holding the cleaning elements 9946 and 9948 respectively. As described in connection with FIGS. 1-6, the cocoons 622 and 624 can form flexible holders for the cleaning elements 9946 and 9948, attached to them, and may allow rotation and / or oscillation of the cleaning elements 9946 and 9948.

7 shows a contour surface 9940 located on the side of the head opposite to the cleaning elements. Contour surface 9940 includes bulges 9950 and recesses 9952 to obtain a curved or wavy surface on the rear surface of the head. The surface 9940 may be relatively smooth for use in massaging oral tissues and, as shown in FIGS. 10 and 12-18, the surface may include elements for cleaning soft tissues to come into contact with soft tissues of the oral cavity and provide the benefits of cleaning them.

Fig. 9 is a plan view of a head 9914 that shows the configuration of toothbrushing elements 9918 for use with head 9914. Cleaning elements 9918 may be formed from elastomeric wall elements, elongated tufts of bristles, or other types of cleaning elements that are independently flexible. Thus, the cleaning elements are capable of providing a limited and controlled flow of dentifrices, as well as maintaining sufficient flexibility to provide improved cleaning of the user's teeth and stimulation of the user's gums with the cleaning elements.

The cleaning elements 9918 are oriented to come into contact with the surfaces to be cleaned in the generally intended direction of use (see FIG. 8), which is generally perpendicular to the surface of the head 9914. The cleaning elements 9918, however, include a mixture of cleaning elements that are aligned (non-inclined) and deviate (inclined) relative to direction A. The location of the inclined and non-inclined cleaning elements ensures effective contact and cleaning of the surfaces of the oral cavity, which is further improved by the movable config atsiey cocoons. The cleaning elements 9946 and 9948 mounted on the cocoons 622 and 624 are adapted to come into contact with the teeth, gums and other oral surfaces of the user in various ways due to the advantages of a flexible base configuration. As such, the cleaning elements 9946 and 9948 include front elements 9950 inclined towards the end of the head and rear elements 9952 inclined towards the handle. As shown, the front and rear elements 9950, 9952 are preferably located on the front and rear sides of their respective cocoons, and more preferably, are located in the corner regions of the cocoons. This arrangement and orientation increases the likelihood that the elements 9950 and 9952 will initially come in contact with the surface being cleaned before other cleaning elements on the corresponding cocoon, which stimulate the bending of the corresponding cocoon when the remaining cleaning elements on it come in contact with the surface.

For example, when the oral care implement 9910 moves forward so that the head 9914 is the front of the toothbrush, the front elements 9950 will be the first to come in contact with the surfaces being cleaned before the rear elements 9952 or other cleaning elements located between the elements 9950 and 9952. The rake angle of the elements 9950 will facilitate backward bending of the cocoons 622 and 624 when the front elements come in contact with the surface being cleaned while the toothbrush advances forward. Bending cocoons back and moving them springy forward, as a reaction to bending, increases the cleaning efficiency of the cleaning elements 9946 and 9948 located on the cocoons. The angular configuration of the elements 9950 and 9952 improves the bending of the cocoons compared to alternative designs in which the cleaning elements are perpendicular to the surface 9954 of the toothbrush and are not inclined forward or backward.

Cleaning elements 9946 and 9948 cocoons also include non-inclined cleaning elements 9954, which are useful for penetrating the surfaces to be cleaned. In addition, the cleaning elements 9946 and 9948 include a pair of bent vertical walls 9956 in the central part of the cocoons. Such walls can be formed as a tightly packed bundle of bristles using the technique of pressing or forming bundles without sealing, or such walls can include elastomeric elements. Other configurations are provided. Each of the walls in pair 9956 has a concave side opposite the concave side of the other wall in pair. The curved configuration and opposing convex sides of the vertical walls 9956 improve the retention of dentifrices between them during use of the oral care product. In addition, the curved configuration provides a pair of solid walls, which in their central location on the cocoon support the cocoon, preventing excessive bending of the cleaning elements 9946, 9948.

Cleaning elements 9942 and 9944, located on fixed bases 616 and 620, are configured to interact with cleaning elements 9946 and 9948 on moving cocoons, as well as for effective cleaning of oral surfaces. Each base includes bristles 9960, a series of vertical walls 9962, and inclined cleaning elements 9964, 9966. The bristles 9960 are a generally non-inclined column that effectively penetrates the cavities and spaces between the oral structures (eg, teeth).

The row of vertical walls 9962 is positioned so that they generally form a concave wall facing the remaining cleaning elements 9918. Thus, the concave wall 9962 of the front base 616 has its concave side facing back to the handle, and the concave wall on the rear base 620 has its concave side facing forward to the other bristles 9918. In this configuration, the opposed concave walls cooperate to hold the dentifrices in the area of the 9918 bristles due to their concave shape, covering the brush teeth, and also with the help of small gaps between the vertical walls, which form concave walls, which reduce the flow of dentifrices between them. In addition, the vertical walls forming the concave walls are non-inclined cleaning elements that support the 9914 head during use and prevent excessive bending of the cleaning elements when an excessive downward force is applied by the user.

Inclined cleaning elements 9962 and 9964 are tilted towards the movable cocoons 622 and 624 to interact with the cleaning elements 9946 and 9948 attached to them for effective cleaning of the surfaces of the oral cavity. As such, the rear base 620 includes forward inclined elements 9964, and the front base 616 includes rearward inclined elements 9966. The inclined cleaning elements 9962 and 9964 are located close to each other within a relative pair of inclined cleaning cocoons 9950 and 9952. Thus, when the cocoons bend back and forth, the inclined cleaning elements 9962 and 9964 are between the corresponding inclined cleaning elements 9964 and 9966. This provides a scissor action that increases cleaning efficiency and eliminates mutual interference between opposing cleaning elements 9964, 9966 and 9962, 9964 that can limit the movement of cocoons.

The cleaning elements described in connection with the embodiment shown in FIGS. 7-9, as well as the following construction options, are preferably formed using a non-embedment beam forming technique according to the prior art. This technique facilitates the manufacture of cleaning element designs that retreat from a traditional stapled perpendicular bundle. With the technique of forming beams without sealing, the fixed ends of the cleaning elements are fused with each other to form a block of cleaning elements, which can then be located on the head plate with different sizes, angles and orientations. Thus, the blocks of cleaning elements as a whole are captured in the structures of the cocoons without being embedded in the carrier medium.

10-13, an oral care implement 10210 is shown in accordance with another embodiment of the invention. As shown, the oral care implement 10210 includes a handle 8103, a head 10214 having cleaning elements 10218 attached thereto on a first side of the head, and soft tissue cleaners 10280 located on a second side of the head that is opposite to the first side. The oral care implement 10210 generally includes objects and features of the oral care implement 9910, with the exception of the configuration of the cleaning elements and the signs of cleaning the soft tissue. The cleaning elements 10218 primarily include vertical walls, which may include an elastomeric element, or may be formed as a tightly packed bundle of bristles by a pressing technique or a bundling technique without sealing. Other configurations are contemplated. The vertical walls provide useful grinding and grinding of teeth in addition to the benefits of brushing. The cleaning elements 10218 also includes a central columnar cleaning element 10270, which may be bristles for penetration to the surfaces of the oral cavity. As shown in FIG. 10, each central cleaning element 10270 protrudes further than other cleaning elements proximal thereto on the same cocoon. In addition, the central cleaning element has a pointed end. As such, the central cleaning element 10270 effectively penetrates and comes into contact with the surfaces of the oral cavity and with the gaps between the surfaces.

Like the configuration shown in FIGS. 4 and 7, and as shown in FIG. 11, the tips or extremities of the cleaning elements 10218 are narrowed so that the cocoons accordingly tend to their adjacent static base, making contact with the surfaces being cleaned. Thus, during use, the cleaning elements 9948 are generally biased towards coming into contact with the cleaning elements 9944 on the rear base 620, and the cleaning elements 9946 are generally biased towards coming into contact with the cleaning elements 9944 on the front base 616. This bias can act along with the movement of the cocoons, which is transmitted due to the contact of the inclined cleaning elements with the surfaces being cleaned when the device is moving. The increasing movement and bending of the bases 622 and 624 further increase the cleaning efficiency of the oral care product.

The soft tissue cleaner 10280 includes a plurality of protrusions 10281 extending from the surface 10284 on the second side of the head 10214, which is generally opposite to the direction in which the tooth cleaning elements 10218. The soft tissue cleaner 10280 is located on a contour surface, such as the contour surface 9940 shown in 7, which includes the bulge 9930 and recesses 9952 to obtain a curved or wavy surface on the second surface of the head. The protrusions 10281 may be separately molded and glued to the contour surface or otherwise attached to it. In addition, they can be formed integrally with the head 10214. Each protrusion can be made of a material different from the material of the other protrusions and / or different from the material of other parts. Soft materials, such as a thermoplastic elastomer or the like, may be attached to the head 10214 to form protrusions. However, harder material or virtually any known material used for the manufacture of oral care products may be suitable for projecting protrusions.

The protrusions 10281 include a plurality of cones 10282 that extend from the contour surface 9940 to come into contact with the soft tissue in the user's mouth. The protrusions 10281 can have many different shapes, structures, sections, configurations, etc., and the soft tissue cleaner can have many different configurations for the protrusions.

As shown in FIG. 13, the cones 10282 generally cover the back surface 10284 in the area of the cleaner 10288, which extends from the area opposite the rear base 620 in the lower part of the head to the area opposite the front side of the base 616 in the end part of the head. Cones are distributed substantially continuously over the area of the purifier. The purifier region includes bulges 10290 near the edge parts of the surface 10284 and the trough 10292 located between the bulges and in the central part of the surface. The configuration of the bulges and depressions increases the effectiveness of the soft tissue cleaner by concentrating the applied force in the protruding parts during initial contact with the soft tissue of the user, which can increase penetration into the soft tissue compared to the relatively flat configuration. When the user exerts additional force, the recesses come in contact with a soft tissue, helping to clean the soft tissues. If excessive force is applied, the recesses help to limit excessive penetration. When the bumps in the areas of the recesses come in contact with soft tissue, they provide the added benefit of removing plaque, which is weakened by the deeper penetration of the bumps on the bulges. Thus, the protrusions on the bulges and depressions interact to initially loosen and then remove plaque on the user's soft tissue.

14 and 15 show another embodiment 10610 of an oral care implement according to the invention. Oral care product 10610 generally includes the same objects and features of the oral care tool 10210, except for the configuration of the protrusions on the soft tissue cleaner 10680. Instead of the existing cones in the area of the purifier, the soft tissue cleaner 10680 includes cones 10282 only on the bulges 10288. Instead, many ribs 10294 are located in some areas of the recesses 10290, including the central part of the surface 10284. The ribs can be made of the same material as the cones , or from another material. For example, cones and ribs may be made of one type of elastomer; however, the elastomer for ridges may be harder than the elastomer for cones.

Ribs 10294 have different lengths that provide different levels of contact with soft tissue during use. As such, longer and shorter ribs can interact to weaken and remove plaque when different crest lengths come into contact with parts of soft tissue in sequence. The ribs 10294 taper from a wide base region located near surface 10284 to a narrower end 10696. In this way, increasing levels of contact with soft tissue are provided depending on the amount of force exerted by the user.

FIG. 16 shows another embodiment 10810 of an oral care implement according to the invention. Oral care product 10810 generally includes the same object and features as oral care tool 10610, except for the configuration of protrusions on a soft tissue cleaner 10880. The soft cloth cleaner 10880 differs from the soft cloth cleaner 10680 in that it does not include ribs 10294. Thus, the soft cloth cleaner includes bumps 10282 that are located only on the bulges 10288 along the side portions of the surface 10284. As such, soft cleaning is provided by the bumps located on the bulges. Soft brushing is useful for the simultaneous functionality of an oral care product, such as when a user brushes his teeth while contacting soft tissues on the inside of his cheek with a soft tissue cleaner 10880. Gentle contact makes for a pleasant sensory stimulation along with soft cleansing of soft tissues.

17 and 18 show another embodiment 10910 of an oral care implement according to the invention. Oral care product 10910 generally includes the same objects and features of the oral care tool 10610, except for the configuration of the protrusions on the soft tissue cleaner 10980. The soft tissue cleaner 10980 differs from the soft fabric cleaner 10680 in that the ribs 10994 are absent in the central part of the surface 10284 but exist in the depressions 10290 located between adjacent pairs of bulges 10288. In addition, the ribs 10994 are generally smaller than the ribs 10294. Essentially a gentle cleaning is provided, which, like cleaning with an oral care product 10810, may be useful when using the simultaneous functionality of the device.

FIGS. 19-20 show an oral care implement 12000 according to another embodiment of the invention. As shown, the oral care implement 12000 includes a pen 8103, a head 12002 having a body 12004, bases or cocoons 12010, 12020, 12032 and 12034 on the front of the head, cleaning elements 12218 that extend from the cocoons, and a soft cloth cleaner 12280, located on the back of the head, which is opposite the front side. The oral care implement 12000 generally includes the objects and features of the oral care implement 10210 shown in FIGS. 10-13, except as described below. A soft tissue cleaner 12280 is generally similar to a soft tissue cleaner 10280. However, various configurations of a soft tissue cleaner can be used, such as, for example, soft tissue cleaners shown in FIGS. 14-18.

The oral care implement 12000 shown in FIGS. 19 and 20 is shown as having four cocoons: a proximal cocoon 12010, a distal cocoon 12020 and two central cocoons 12032 and 12034. The proximal and distal cocoons depart from the body 12004, which is located on the back heads. The embodiment shown in FIGS. 19 and 20 differs from the designs shown in FIGS. 1-18 in that the central cocoons 12032 and 12034 are not directly connected to the rear housing of the head housing 12002, but rather are suspended between the proximal cocoon 12010 and a distal cocoon 12020. The proximal cocoon and the distal cocoon are attached to the body, while the central cocoons are suspended above the body. Essentially, the central cocoons are spaced from the body in such a way that between them there is a gap of 12050.

The central cocoons 12032 and 12034 are suspended using bridge supports 12060, which may include a pair of substantially parallel supports 12067 separated by a gap 12065. The first bridge support extends longitudinally between the proximal cocoon 12010 and the central cocoon 12034, and the second pair of bridge supports extend longitudinally between distal cocoon 12020 and central cocoon 12034. In addition, the bridge support runs longitudinally between the central cocoons 12032 and 12034. Thus, each central cocoon is supported by a pair of opposite bridges X supports.

Although the embodiment shown has pairs of supports 12067 on each side of each central cocoon, other configurations are contemplated. For example, instead of a pair of supports 12067, one bridge element may be located between the proximal or distal cocoon and the adjacent central cocoon and between two central cocoons. Such a single bridge may be wider than each individual pair of supports 12067, such that the width of one bridge support is generally equal to the width of the pair of supports plus the gap 12065 between them.

Central cocoons 12032 and 12034 as a whole have greater degrees of freedom than proximal and distal cocoons. In one configuration, the bridge supports 12060 and 12070 are substantially rigid. Even so, the suspension device provides a moderate degree of flexibility for the central cocoons. In a preferred, more flexible configuration, the bridge supports 12060 and 12070 are flexible features that allow the cleaning elements passing from the central cocoons 12032 and 12034 to have a much greater range of motion than the cleaning elements passing from the proximal and distal cocoons 12010 and 12020, respectively, which are generally static or motionless. Flexible bridge supports can be formed from an elastic material such as a thermoplastic elastomer. Other rubber-like materials may be used, such as other thermoplastic resins or thermoplastic urethane, or a plastomer or any combination thereof.

In a flexible configuration, the bridge supports 12060 and 12070 are flexible and allow the central cocoons to rotate around the axis of their base and / or move to the housing 12004 when a downward force is applied to the central cocoons during use of the tool. In addition, the elastic nature of the bridge supports can allow the central cocoons to return to their original shape or initial position when the force is reduced. In addition, when the oral care product is moved in a longitudinal direction parallel to the handle 8103, the central cocoons may deviate longitudinally when they come in contact with the surface being cleaned. The deviation of the central cocoons in the longitudinal direction can also be due to the elastic nature of the bridge supports 12060 and 12070. Such a return action can create an active movement in the direction opposite to the direction of movement, which helps to brush your teeth by creating additional cleaning strokes.

The distance between the proximal cocoon 12010 and the distal cocoon 12020 may be greater than the width of each of the central cocoons 12032 and 12034, and in the embodiment shown in FIG. 19 is approximately two widths of one of the central cocoons. In addition, in the shown embodiment, the central cocoons 12032 and 12034 are suspended at a distance less than the thickness of the central cocoons 12032 and 12034 from the body. The length of the bridge supports 12060 and 12070 can be significantly less than the length of the central cocoons 12032 and 12034 , and in the configuration shown in FIGS. 19 and 20, is approximately 1/5 of the length of the central cocoons. As a result, with two central cocoons in the configuration shown in FIGS. 19 and 20, the bridge supports 12060 and 12070 cover less than 25% of the total distance between the proximal and distal cocoons 12010 and 12020, respectively.

In addition, the configuration shown in FIGS. 19 and 20 includes a unitary unit 12500 (reference number not shown) that forms the top of the proximal cocoon 12010, the top of the distal cocoon 12020, bridge supports 12060 and 12070 and central cocoons 12032 and 12034. Unitary block 12500 may be made of an elastomeric material, such as a soft thermoplastic elastomer (thermoplastic elastomer). Again, other rubber-like materials may be used, such as other thermoplastic resins, or thermoplastic urethane, or plastomer, or any combination thereof. The upper parts 12033 and 12035 of the proximal and distal cocoons can be attached to protrusions (not shown) extending from the underlying head 12002, thus providing sufficient support and strength for the proximal and distal cocoons 12032 and 12034. The upper parts can also be formed as unitary signs along with the body of the head, for example, from a unitary plastic casting. When they are formed as various features, the proximal and distal cocoons can be formed from the same material as the body, bridge supports and / or central cocoons, or from another material. For example, bridge supports and central cocoons may be made of a first thermoplastic material, and proximal and distal cocoons may be formed separately of a second thermoplastic material, such as polypropylene. In this configuration, the bridge supports and central cocoons can be made as a unitary structure, which is welded or glued to the proximal and distal cocoons. In addition, bridge supports, central cocoons and the upper parts of the proximal and distal cocoons can be formed as a unitary element that is attached to the body.

As described with respect to the embodiment shown in FIGS. 7 and 8, the cleaning elements 12218 mounted on the central cocoons can be adapted to come into contact with the teeth, gums and other surfaces of the user in various ways due to the advantage of a flexible base configuration. For example, as shown in FIG. 19, cleaning elements located on central cocoons may include front elements 12090 tilted toward the end of the head and rear elements 12092 tilted toward the end of the handle. The location and orientation of these front and rear elements may increase the likelihood that such elements will initially come in contact with the surface being cleaned before other cleaning elements on the corresponding cocoon, thereby stimulating the bending of the corresponding cocoon when other cleaning elements located on it come into contact with the surface.

As also shown in FIG. 19, the cleaning elements 12218 may include vertical walls 12094, which may be made of elastomer or based on bristles, as described above. Vertical walls can provide beneficial rubbing and grinding of teeth in addition to the benefits of brushing. Cleaning elements 12218 may also include a central columnar cleaning element 12270, which may include one or more bristles to penetrate the surfaces of the oral cavity. Columnar cleaning elements may protrude further than other cleaning elements located close to them on the same cocoon, and they may have a generally pointed end. Essentially, the central cleaning element 12270 can effectively penetrate and come into contact with the surfaces of the oral cavity and the gaps between the surfaces.

The tips or ends of the cleaning elements 12218 can be narrowed so that the suspended cocoons are respectively carried away to their adjacent proximal or distal cocoon 12020 and 12010, respectively, making contact with the surfaces being cleaned. Thus, during use, the cleaning elements extending from the central cocoon 12032 can generally be displaced in the direction of contact with the cleaning elements departing from the proximal cocoon 12010, while the cleaning elements departing from the central cocoon 12034 can be generally displaced in the direction of contact with the cleaning elements, departing from the distal cocoon 12020. This displacement can interact with the movement of the cocoons caused by the contact of the inclined cleaning elements with clean E surfaces when the device is moved. The increased movement and bending of the suspended central cocoons 12032 and 12034 further increase the cleaning efficiency of the oral care product.

FIG. 21 shows a toothbrush 13000, which is similar to the design shown in FIGS. 19 and 20 and generally has the same objects and features, except for its central cocoon and configuration of the cleaning elements 13218 and the absence of a soft tissue cleaner. Toothbrush 13000 includes a handle 8103 and a head 13002 having a combination of fixed and suspended cleaning elements. Head 13002 includes a housing 13004, proximal and distal cocoons 13010 and 13020, and one central cocoon 13050 suspended between the proximal and distal cocoons. The handle 8103, the head 13002, and the proximal and distal cocoons 13010 and 13020 can be formed as a unitary structure of a thermoplastic material such as polypropylene.

One central cocoon 13050 has an elastomeric section 13055 located in the middle of the central cocoon. The elastomeric section is preferably made of an elastic material, such as a soft thermoplastic elastomer, while the central cocoon is preferably made of a harder material, such as polypropylene. The central cocoon 13050 is held in place by a molded thermoplastic elastomer membrane 13070 that is connected to the proximal and distal cocoons 13010 and 13020 to form bridge supports 13060. The membrane 13070 can form a loop that spans a pair of fixed proximal and distal cocoons 13010 and 13020 and is attached to opposite sides of the central cocoon 13050. Grooves (not shown) in the sides of the proximal and distal cocoons, as well as the central cocoon, can receive the membrane 13070. In addition, the membrane and 13070 may be attached to the pods by means of adhesive and / or by melting.

The membrane 13070 allows the central cocoon 13050 to move towards the housing 13004 when sufficient force is applied during the cleaning operation. When such a force is applied to the central cocoon, the opposite halves of the central cocoon 13051 and 13053 will also bend around the elastomeric section 13055. As a result, two sets of cleaning elements 13218 extending from each end of the central cocoon 13050 can rotate towards each other. The central cocoon 13050 can bend back to its original position when the force acting on the central cocoon and moving it to the head 13002 decreases.

The cleaning elements 13218, departing from the central cocoon 13050, generally taper in the center, which is generally the opposite orientation with respect to the configuration of the cleaning elements shown in FIGS. 10 and 11 and FIGS. 19 and 20. The central cone allows the cleaning elements 13218 to penetrate interdental spaces of the user's teeth when moderate force is applied to the toothbrush 13000 in the direction of the teeth. When the user exerts a more excessive force on the toothbrush, the central cocoon 13050 moves into contact with the housing 13004, which causes the central cocoon to bend around the elastomeric section 13055 and further come into contact with the interdental space to which the cleaning elements are attached.

On figa and 22B shows a toothbrush 13010, which is similar to the design variant shown in Fig.21, and generally has the same objects and features as the toothbrush 13000, except for touching its body. As shown, the housing 13007 includes an elastic hinge element 13080 located in the Central part of the housing and intersecting it in width. The hinge element may be formed of a thermoplastic elastomer or other elastic material that is more flexible than other parts of the body. The hinge element may also include an area of reduced thickness of the housing around which a thermoplastic elastomer or other elastic material is located. For example, the proximal casing part 13082 and the distal casing part 13084 may be formed from a relatively hard material, such as polypropylene material, and may include a thin neck region (not shown) located between them. The neck region can allow the proximal and distal parts of the body to rotate relative to each other. Elastic material 13081 may surround the neck to reduce rotation around the neck. The resilient material may be bonded to the body via adhesive bonding, fusion bonding, or other attachment mechanism, such as compression fit around the neck.

The hinge element 13080 allows the proximal and distal parts 13082 and 13084, respectively, of the housing 13004 to rotate relative to each other during use. Thus, the head 13010 can generally be twisted or bent around a surface to be cleaned, such as a user's tooth, as shown in FIG. 22B. In addition, the hinge element 13080 can simply improve the overall flexibility of the head to adapt to various signs of cleaning, orientation of use and applied forces. For example, as shown in FIG. 22B, the hinge member 13080 may allow the housing 13007 to bend in an arc. In another example (not shown), the hinge element 13080 may allow the tip of the head to bend backward, which will facilitate the movement of the central cocoon 13050 from the housing when the bridge supports are pulled.

On figa and 23B shows the means 13020 care for the oral cavity, which is similar to the design shown in Fig.21, and generally has the same objects and features as the toothbrush 13000, with the exception of touching its Central cocoon, the location of the cleaning elements 13218 and having a cleaner 13280 soft tissue located on the back side of its head, which is opposite the front side. The soft tissue cleaner 13280 is generally the same as the soft tissue cleaners 10280 and 12280 of FIGS. 10-13 and 19-20, respectively. However, various soft tissue cleaner configurations may be used, such as soft tissue cleaners shown in FIGS. 14-18. Toothbrush 13020 includes a central cocoon 13058, which is essentially unitary and does not have an elastomeric section 13055 of the toothbrush 13000. Thus, the central cocoon can provide relatively stable contact with the cleaned elements of the oral cavity due to the larger rigid central cocoon, while maintaining benefits, provided by its suspended configuration. Essentially, the central cocoon can adapt to the cleaning forces exerted by the head by moving forward, backward, sideways and / or downward relative to the housing. However, its relatively large size and rigidity provide a uniform orientation for a large number of cleaning elements 13218 attached to it.

The cleaning elements 13218 that extend away from the central cocoon are similar to the cleaning elements 12218 of the toothbrush 12000 and generally include the same configuration, objects and features as the cleaning elements 12218 shown in FIG. 19. However, since the central cocoon 13058 is the only cocoon that covers the same distance as the central cocoons 12032 and 12034 of the toothbrush 12000 in FIG. 19, the central cocoon 13058 includes additional cleaning elements in its central region. As shown in FIG. 23A, a central columnar cleaning element 13096 is located in a central part of a central cocoon that is similar to columnar cleaning elements 12270 of a toothbrush 12000. A columnar cleaning element 13096 interacts with columnar cleaning elements 12270 to effectively penetrate and come into contact with cavity surfaces the mouth and the gaps between the surfaces and transmit downward force to the central cocoon when excessive cleaning force is applied to the cleaning elements. In addition, several radial cleaning elements 13098 depart from the central columnar cleaning element 13096 as a whole in a knitting-like configuration in the central region of the central cocoon. Radial cleaning elements come in contact with the features being cleaned throughout the central part of the cocoon and form the perimeter structure in the lateral parts of the central cocoon. The perimeter structure enhances the contact of the cleaned signs of the oral cavity and can help to keep the dentifrice within the cleaning elements of the central cocoon during use.

On figa and 24B shows a toothbrush 14000, which is similar to the design shown in Fig.21, and contains a handle 8103 and a head 14002 having a combination of fixed and suspended cleaning elements. Head 14002 includes a housing 14004, proximal and distal cocoons 14010 and 14020 having cleaning elements 14018, and a single central cocoon 14050 suspended between the proximal and distal cocoons. The handle 8103, the head 14002 and the proximal and distal cocoons 14010 and 14020 can be formed as a unitary structure of a thermoplastic material such as polypropylene. The soft tissue cleaner 14280 is generally the same as the soft tissue cleaners 10280 and 12280 of FIGS. 10-13 and 19-20, respectively. However, various configurations of a soft tissue cleaner may be used, such as the soft tissue cleaners of FIGS. 14-18.

The central cocoon 14050 has an elastomeric section 14055 located in the middle of the central cocoon, or, more specifically, between a pair of cocoon segments. The elastomeric section is preferably made of an elastic material, such as a soft thermoplastic elastomer, while the central cocoon is preferably made of a harder material, such as polypropylene. The central cocoon 14050 is held in place by a molded thermoplastic elastomer membrane 14070 that is connected to the proximal and distal cocoons 14010 and 14020 to form bridge supports 14060. The membrane 14070 can form a loop that spans a pair of fixed proximal and distal cocoons 14010 and 14020 and is attached to opposite sides of the central cocoon 14050. Grooves (not shown) in the sides of the proximal and distal cocoons, as well as the central cocoon, can receive the membrane 14070. In addition, the membrane and 14070 may be attached to the pods by means of, for example, adhesive bonding and / or fusing compound.

The cleaning elements 14218 on the central cocoon 14050 are similar to the configuration of the cleaning elements shown in FIGS. 19 and 20, with the exception of the plurality of central flexible cleaning elements 14270 extending from the housing 14004 and passing through one or more holes (not shown) in the central cocoon 14050. Cleaning element 14270 also contains massaging and / or grinding elements 14272 on its upper surface. Although two cleaning elements 14270 are shown, it will be appreciated that only one or more than two cleaning elements 14270 can be used, as desired. The cleaning element 14270 can be attached to the housing 14004 or pass through the housing 14004 from the soft cloth cleaner 14280 on the opposite side of the head 14002. In the latter case, the cleaning element 14270 can be cast simultaneously with the soft cloth cleaner 14280. In any case, the unitary structure formed by the membrane 14070 supporting cocoons 14010, 14020 and 14050 can be connected to the base 14004 over the cleaning elements 14270. Other construction methods are contemplated.

The membrane 14070 allows the central cocoon 14050 and the cleaning elements 14218 to move toward the housing 14004, being guided by the cleaning elements 14270 when sufficient force is applied during the cleaning operation. This movement provides additional functionality not described above. One such feature is the grinding of a tooth in the middle of the head, which is surrounded by fixed and movable cleaning elements 14018, 14218, respectively. In addition, the cleaning element 14270 includes massaging and / or grinding elements 14272 that are at a fixed height relative to the head 14004 and yet are surrounded by cleaning elements 14218 that recede to the head 14004 under the cleaning pressure, allowing the cleaning elements 14272 to be more effective during cleaning .

When the cleaning pressure is applied to the central cocoon 14050, the segments 14051 and 14053 of the central cocoon 14050, as well as the cleaning elements 14270, will bend around the elastomeric section 14055. As a result, the cleaning elements 14218 extending from both ends of the central cocoon 14050, as well as the cleaning elements 14270, can be rotated to each other. The central cocoon 14050 can bend back to its original position when the force exerted on the central cocoon, moving it to the head 14002, decreases.

On figa-25E shows a toothbrush 15000A-C, which is similar to the design shown in figa and 23B, and includes a handle 8103 and a head 15002 having a combination of fixed and suspended cleaning elements. Head 15002 includes a housing 15004, proximal and distal cocoons 15010 and 15020 having cleaning elements 15018, and a central cocoon 15050 formed by segments of cocoon 15051-15054 (design options shown in figa-25D), or segments 15055-15058 cocoon ( design variant shown in FIG. 25E) suspended between the proximal and distal cocoons. Handle 8103, head 15002, and proximal and distal cocoons 15010 and 15020 can be formed as a unitary structure from a thermoplastic material such as polypropylene.

Segments 15051-15058 of the central cocoon are held in place by a molded membrane 15070 of thermoplastic elastomer that connects to the proximal and distal cocoons 15010 and 15020 to form bridge supports 15060. Membrane 15070 can form a loop that spans a pair of fixed proximal and distal cocoons 15010 and 15020 and segments of the central cocoon 15051-15058, which can be separated by a flexible gap 15062 along the longitudinal axis (design variant shown in figa and 25B) or the transverse axis (design variant, according to 25C and 25D) of the head 15002. Alternatively, the segments 15055-15058 of the design shown in FIG. 25E may be separated by a flexible gap 15062 along the longitudinal and transverse axes of the head. The grooves (not shown) in the cocoons can receive the membrane 15070. In addition, the membrane 15070 can be attached to the cocoons, for example, using adhesive bonding and / or fusion bonding.

The cleaning elements 15218 on the central segments of the cocoon are similar to the configuration of the cleaning elements shown in FIGS. 23A and 23B, with the exception of the central cleaning element 15270 having polishing ribs 15272 on its upper surface that pass through an opening (not shown) in the membrane 15070. Such a cleaning element 15270 functions like a cleaning element 14270 in FIGS. 24A and 24B, with respect to membrane 15070 and central cocoon segments 15051, 15053 in FIGS. 25A and 25B. However, since the central cocoon segments 15051, 15053 are separated along the longitudinal axis of the head 15002 by the gap 15062, such segments 15051, 15053 will tend to rotate from the protruding cleaning element 15270 or rotate around the cleaning element 15270 under the cleaning pressure, thereby simulating the movement of the bird's wings, resulting in to increase efficiency and penetration into the interdental space. Similar movement is tested along the transverse axis with segments 15052, 15054 in FIGS. 24C and 24D, and even more extensive movement is tested along the longitudinal and transverse axes with segments 15055-15058 in FIG. Thus, the cleaning element 15270 forms a central pivot point around which the cocoon segments 15051-15058 can move.

The cleaning element 15270 can be attached to the housing 15004 or pass through the housing 15004 from a soft tissue cleaner (not shown) on the opposite side of the head 15002. In the latter case, the cleaning element 15270 can be cast simultaneously with the soft tissue cleaner. In any case, the unitary structure formed by membrane-bearing 15070 cocoons 15010, 15020 and segments 15051-15058 of the central cocoon 15050 can be connected to the base 15004 over the cleaning element 15270. Other construction methods are contemplated.

As shown in FIGS. 26 and 27, the toothbrush 16000 comprises a handle 8103 and a head 16002 having a combination of fixed and suspended cleaning elements. Head 16002 includes a housing 16004, proximal and distal cocoons 16010 and 16020 having cleaning elements 16018, and a central cocoon 16050 formed by segments of cocoon 16051 and 16053 suspended between the proximal and distal cocoons. Handle 8103, head 16002, and proximal and distal cocoons 16010 and 16020 can be formed as a unitary structure from a thermoplastic material such as polypropylene.

Segments 16051 and 16053 of the central cocoon can be separated by a bridge 16052, which is preferably flexible and formed from the same material as the thermoplastic elastomer membrane 16070, which is connected to the proximal and distal cocoons 16010 and 16020 to form bridge supports 16060. Membrane 16070 can form a loop that encompasses a pair of fixed proximal and distal cocoons 16010 and 16020 and a central cocoon 16050 including segments 16051 and 16053, which can be separated by a flexible gap of 16062 d the transverse axis of the head 16002 and / or along the longitudinal axis, as shown in other designs (see, for example, Fig.25A-25E). The grooves (not shown) in the cocoons can receive the membrane 16070. In addition, the membrane 16070 can be attached to the cocoons, for example, using an adhesive joint and / or fusion joint.

The proximal and distal cocoons 16010 and 16020 can be integral with the head body 16004 so that the membrane extends around the central part of such cocoons, or the cocoons can end at the edge of the membrane 16070 (see cocoon base 16050 in FIG. 27) and attach to the body 16004 heads by ultrasonic welding, glue or similar. Accordingly, the membrane 16070 can serve as an external housing for the plate of cleaning elements included in the cocoons 16010, 16020 and 16050, and the plate can be attached as a single element to the housing 16004 of the head. Thus, cocoons 16010, 16020 and 16050 can be assembled and handled as a single element and can be attached to the head housing 16004 as a single element at the proximal and distal ends of the head housing 16004.

On Fig shows the construction of the part of the cocoon 16050 and, more specifically, the part of the cocoon 16051, in which the base 16019 of the cleaning elements 16018 are molded to form the mat 16021, and the mat 16021 is caught between the cocoon body 16053 and the ceiling 16054. Mat 16021 prevents the passage of the cleaning elements 16018 through the holes for the beam of the body 16053 cocoon. The floor 16054, for example, can be glued or welded to the body 16053, and the floor 16054 is at least partially surrounded by a membrane 16070. Thus, the cleaning elements 16018 in this embodiment are captured and secured within the cocoon body 16053 and the floor 16054, known as bundle formation without embedment, but such cleaning elements are not rigidly and firmly attached to any particular supporting structure such as a stapled bundle, they are fixed inside the bundle opening.

The cleaning elements 16018 on the proximal and distal cocoons 16010 and 16020 can be held using the bead-free bundling method, as described above, according to which they can be trapped between the corresponding cocoon body and the head body, or they can be attached to cocoons 16010, 16020, if such cocoons constitute an integral extension of the head housing 16004. If they were made using the method of forming beams without sealing, the connection between the cocoon body and the head body can be an edge connection, while the cocoon body, for example, is welded to the head body at the periphery of the cocoon body so that the mat of fused ends of the bristles is between the body cocoon and head housing.

When brushing with a toothbrush, for example, shown in FIGS. 22A-22B, which has a head of a toothbrush that consists of several areas with attached cleaning elements (proximal and distal ends) connected by a flexible central rubber-like field, the central area may drop and touch with the head housing located below in an uncontrolled manner (see figv). As a result, ringing noise may occur, significant “slipping / stretching” of the central part of the flexible area with the block (s) of cleaning elements embedded in it, which may cause damage to the structure or user. By including bases that protrude upward from the brush head, movements of the flexible area can be controlled with the intention of allowing the flexible area to move in a certain way relative to the brush head.

FIGS. 26 and 27 show one example of one central protrusion 16270 extending from a soft tissue cleaner 16280 on the rear side of the head 16002 to a recess or recess 16055 located in the overlap 16054 of the block 16050 beams. Such a protrusion 16270 is preferably formed or molded integrally with a soft tissue cleaner 16280 from a flexible material, although this is not necessary, and forms a pivot point for the cocoon 16050. This allows the cocoon 16050 to move in a controlled manner relative to the head body 16004. Depending on the flexibility of the protrusion 16270, the cocoon 16050 may also be able to move normally or move toward the head housing 16004 (again, for example, see FIG. 22B). Alternatively, the protrusion 16270 may be rigid and extend from the head housing 16004 to provide a rigid pivot point that resists the normal movement of the cocoon 16050 to the head housing 16004. Of course, although one central protrusion 16270 is shown in FIGS. 26 and 27, the number and type of protrusions or supports may vary, as shown, but not limited to, in FIG. 28 (a plurality of supports 17270 and 17271 extending between the head housing 17004 and the central cocoon 17050) and Fig. 29 (transverse plate support 18270 extending from the head housing 18004 along the transverse axis of the central cocoon 18050 of the toothbrush 18000, creating linear contact with the central cocoon 18050). Each of the design variants shown in FIGS. 26-29 allows a unique movement of the flexible cocoon relative to the head housing, while the structure shown in FIGS. 26-27 allows rotation of at least 360 degrees, the structure shown in FIG. .28 allows more limited rotational movement, and the structure shown in FIG. 29 allows swinging movement on the protrusion 18270.
