This invention relates to toothbrushes, and more particularly to toothbrushes that can manipulate the position of the head by applying pressure to a specific section of the handle. 5 Background of the Invention Traditional toothbrushes include a uniform tuft of bristles, each bristle having a first end that is held tethered and secured to the -brush head, and a second end that is free and used to brush teeth. The free ends of the different bundles present a surface envelope, which can be slightly deformed by the bending of the bristles when the free ends of the bristles are in contact with the surface to be brushed, but cannot properly fit the complex shapes. surface. Such complex surfaces exist in the mouth, where the teeth are arranged approximately in a C-shaped curve in the upper and lower jaws, and each row of teeth therefore has a convex outer curve and a concave inner curve. When brushing the teeth, the user's desire to match the bristles with the teeth is to use the toothbrush vigorously so that the bristles are properly transformed into an accurate dentition profile. Such forceful use of the toothbrush only causes excessive wear on the tooth surface and the gums, and does not allow the toothbrush to properly fit the teeth to provide the desired cleaning. A toothbrush having a flexible neck 20 between a bristle-containing brush head and a handle has been disclosed in the prior art to provide a toothbrush with a tooth profile. Examples of such flexible neck toothbrushes include the toothbrushes disclosed in U.S. Patent Nos. 759490 and 4520526. U.S. Patent No. 759490 creates a flexible neck by inserting a soft and elastic material between the rigid brush head and the handle. This flexible and elastic material can be used in accordance with the Chinese National Standard (CNS) A4 for this paper size.

U.S. Patent No. 526 produces the crotch by removing a portion of the material from the top and bottom of the toothbrush, by having a hollow shape extending from the -side to the other side of the neck—1 The eruption toothbrush neck allows the brush head to yield relative to the handle when excessive force is applied to the 5 users, thereby reducing the risk of damaging teeth and gums. However, this recording mechanism does not give the user the ability to control the contour of the brush head to a particular arched inner surface of the mouth being brushed to avoid having to apply excessive force at first. U.S. Patent No. 4,333,199 discloses a toothbrush whose head is mounted on a coil spring above a recessed 10-in handle, so that the head can be rotated and tilted when used for teeth. Although this flexible effect allows the toothbrush head to generally follow the arch of the inner surface of the mouth being brushed, it does not provide any direct control of the user's movement, tilt, and rotation of the toothbrush head. 0 15 PCT International Application W089 / 10076 discloses a toothbrush having the ability to change the angle between the brush head and the handle to position the brush head in parallel with the arcuate portion of the dentition. W089 / 10076 discloses a toothbrush with a handle pivotally connected to the head, where the handle is formed by a pair of spaced apart rigid upper and lower sides that are pivotally connected to move in a direction of length 20 relative to each other . Alternatively, the spaced-apart rigid upper and lower sides may be connected by an elastic spacer layer, which will also allow the two to move in the length direction relative to each other. It is difficult to accurately control the position of the toothbrush head using such a pivotally connected handle and head controlled by the longitudinal movement of the rigid two sides of the toothbrush. The lack of this precise control is due to the lack of rigidity. -4- The paper size is suitable for the National Fresh (CNS) A4 specification (210: 297 mm)

The head 14 has a surface 20 on the upper side 13 and the rows of bristle tufts 22 extending from this surface are transverse to the longitudinal axis A-A. According to the present invention, the head 14 may flex relative to the handle 18 in the vertical plane indicated by V in FIG. 1A, but is substantially rigid relative to the handle in the horizontal 10 plane indicated by η in FIG. This flexibility is due to the fact that the handle 18 is multi-segmented, it is formed from two parts made of a material with significantly different elastic modulus, one part is formed by a fairly rigid plastic, and the other Partly formed from a flexible, flexible elastomer. The rather rigid plastic portion contains a generally S-curved longitudinal back bone 26 extending from the neck of the toothbrush to its widened base 1524. The flexible pliable elastomeric portion 28 is also substantially s-curved, and is substantially s-curved into the longitudinal back bone 26, so that the opening of the rigidly s-curved rigid longitudinal dorsum is elastically pliable. The S curve of section 28 is closed. The S-curved rigid longitudinal back bone 26 and the relatively substantially S-curved elastic 20 flexible elastic body portion 28 together form the shape of a substantially elongated number 8. The interlocking s-curves forming a handle of the shape of approximately number 8 define two openings, namely an upper opening 30 closer to the neck 16 and a lower opening 32 closer to the base 24, the two openings preferably having approximately equal Sectional area.

Description of the invention (6) Openings 30 and 32 have Sufficient cross-sectional area, so that when the user applies a greater force to the relatively rigid flexible portion around the upper opening 30 than the relatively elastic and flexible portion around the upper opening 30, When a large amount of force is applied to the relatively fairly rigid back bone portion around the lower opening 32, the connected bristle bearing head 14 is deflected to a position in the direction of the upper side 13 of the toothbrush. The force involved in this manipulation by the user is shown in Fig. 1 by opposing arrows at acute angles to the longitudinal axis A-A. Accordingly, the user can apply a relatively large amount of force to the rather elastic flexible portion 28 around the upper opening 30 at a suitable angle than the corresponding rigid back bone 26 applied to the corresponding 10 by the upper opening 30, so that The bristle-bearing head 14 is deflected to a position opposite to the toothbrush (that is, away from the upper side 3). The S-curve-shaped portion forming the interlock of the handle is shown in FIG. 丨 as being substantially equally spaced relative to the longitudinal axis AA, but in another embodiment of the present invention 15, the S-curve of the interlock may be as shown in FIG. 2 It is shown in front of the longitudinal axis AA, or as shown in FIG. 3, behind the longitudinal axis AA. In addition, although in the figure, the openings 30 and 30 are substantially oval and have a transverse axis that is relatively narrow relative to the longer longitudinal axis, and the longer longitudinal axis may be aligned or aligned with the longitudinal axis A-A of the toothbrush Sharp 20 angles, but these openings may be circular and have a greater length of the transverse axis than the length of the longitudinal axis, as shown in FIG. 2.

Description of the invention (7) Other plastics with a rigid structure are molded into a whole workpiece, such as polyamide, that is, financial theory; S purpose, such as polyethylene terephthalate (PET), or acid-modified polycyclohexylene 5 dimethylene terephthalate (PCTA); or cellulose plastic ; Or styrene acrylonitrile (SAN) or acrylonitrile butadiene styrene (ABS). Polypropylene or other rigid plastics preferably have a Shore A Hardness ranging from 40 to 110, more preferably 60 to 110, and most preferably 80 to 100. A suitable polypropylene is available from Huntsman Corporation of Longview (75603), Texas under the trade designation Huntsman Polypropylene P4G3Z-039. The relatively elastic, flexible elastomeric S-curve portion 28 may be molded from a variety of different elastomeric materials, especially thermoplastic elastomers 15 (TPE). Acceptable TPE materials for the relatively elastic flexible elastomer s-curve section 28 include styrene-ethylene / butene-styrene (SEBS) type styrene block copolymers such as styrene-butadiene Monostyrene, styrene-isoprene styrene, and related copolymers, and thermoplastic polyurethane (TPU) or thermoplastic vulcanized rubber 20 (vulcanate (TPV)), which is composed of polypropylene and EPDM (Ethylene propylene diene monomer), which can be obtained as 88111; 00 generation 116 (brand) described in US Patent No. 5,393,796, or Vyram (brand), a mixture of polypropylene and natural rubber Another TPV, Santoprene and Vyram are made by Akron -9 of Ohio.

Another preferred TPE is Dynaflex G6713 (brand) marketed by GLS Corp. of Gary (60013), Illinois. These and other suitable elastomers typically have a Shore A hardness from about 1 to 94, preferably 5 to about 15 to 60, and more preferably about 15 to 40. As shown in the cross-sectional view of Fig. 4, a flexible, flexible elastomeric material can be molded around the handle 18 to form an elastomeric overmold area. The S-curved portion of the elastic flexible elastomer is shown in Figure 4 as regions 38 and 40, which are separated in the section shown by a substantially elongated S-curved shape of the rather rigid back bone 26. The degree of flexibility of both the rather rigid back bone portion 26 and the elastic pliable elastomeric S-curve portion (regions 38 and 40) can be further controlled by changing their thickness, i.e. providing greater or lesser Softness. If the rather rigid components of the toothbrush want a substantially transparent is appearance, the toothbrush head 14, neck 16, fairly rigid, substantially S-curved back bone portion 26, and base 24 may be aligned, for example Polyester of polyethylene terephthalate, or copolyester such as PCTA or SAN, or cellulose plastic such as cellulose acetate propionate (CAP). If the toothbrush's flexible, flexible elastomeric group of 20 pieces wants a substantially transparent appearance, that is, the elastic and flexible S-curve elastomer portion 28, then some TPE, or TPUS, or vinyl acetate Vinyl ester (EVA) material.

Invention Description (9 ) Another embodiment of this Maoming may include not only the two openings previously discussed, but also the single-openings or clusters in each segment. Multiple openings, also P_four, five, or six openings. In the case where there is a single or a group of 5 openings in the handle W, the rather rigid back bone forms the first side of each opening or group of openings, while the relatively elastic flexible body forms each opening or group of openings. Second side. The opening may be generally meniscus-shaped, substantially oval-shaped, or substantially circular, and its longitudinal axis may be substantially aligned with or acutely aligned with the longitudinal axis A-A of the toothbrush. The plurality of openings can all be positioned around the longitudinal axis of the toothbrush 10, or on either side thereof. Examples of such alternative embodiments are shown in Figs. 6, 7, and 9. Because embodiments of the present invention that include a widened base that is employed with the integral two-component construction greatly increases the weight of a typical toothbrush, the base can be hollow to minimize additional weight. As shown in Fig. 5, such a hollow base 15 may be formed of a relatively rigid polypropylene casing 34 which is injection-molded by an interior surrounded by an elastic flexible elastomeric material 36 composed of an elastic flexible elastomeric material. Alternatively, as shown in FIG. 10, the present invention may contain a typical narrow toothbrush base to reduce the added weight. The multi-component toothbrush of the present invention can be molded by conventional injection molding techniques known in the art. For example, according to the present invention, a portion of a flexible, flexible elastomeric material may be injected into the head 14, the neck 16, the fairly rigid handle back bone portion 26, and the frame or backbone of the base 24 including hard bristles. After the first forming step, it is molded around the handle 18 by the second injection forming step.
