Description

Oral care system

The present invention is directed to an oral care system.

Many people use oral health appliances (especially toothbrushes) every day. A typical oral health care device includes an extended grip and a head attached to one end of the grip. The grip provides a structure by which a user can hold and manipulate the oral care implement during use. The head generally includes one or more elements designed to perform their intended function, such as a tooth cleaning element, a soft tissue cleaning element, and/or an oral care agent.

Over the years, efforts have been made to improve the design of grips for oral health appliances in order to provide users with increased control of the appliance and to improve the range of components contained in the head for oral care during oral health care sessions. The appliance can deliver improved cleaning of the user's mouth. Such efforts have included the development of grips having multiple components, including a hard core structure and a softer gripping cover or gripping body, in an attempt to increase user control of the appliance.

The body 140 is immovable relative to the head 120. The body 140 and the head 120 are unitary in unitary construction. However, in other embodiments, the head 120 and the body 140 can be formed as separate components that are tied to subsequent stages of the process by any suitable technique known in the art (including but not limited to thermal welding, sonic welding) , a tight fit assembly, a coupling sleeve, an adhesive, a snap, and a snap connection are operatively connected. In all embodiments, whether the head 120 and the body 140 are constructed as a single-piece or multi-part assembly (including joining techniques) is not a limitation of the present invention. Further, other manufacturing techniques may be used in place of injection molding and/or in addition to injection molding to construct the grip 110 and/or the head 120 (or elements thereof), such as milling and/or machining.

In this embodiment, each of the head 120 and the body 140 is constructed of a rigid or rigid material, particularly a hard plastic polypropylene (PP). However, in various variations with respect to this embodiment, the head 120 may alternatively or alternatively be constructed from one or more of the following rigid or rigid materials: polyethylene, polypropylene, polyamide, polyester, fiber. , styrene-acrylonitrile (SAN), acrylic, acrylonitrile butadiene styrene (ABS) and a thermoplastic. Again, in various variations with respect to this embodiment, the body 140 may alternatively or alternatively be constructed from one or more of the following rigid or rigid materials: polyethylene, polypropylene, polyamide, polyester, cellulose. , styrene-acrylonitrile (SAN), acrylic acid, acrylonitrile butadiene styrene (ABS) and a thermoplastic.

We should note that relative terms, such as distal, intermediate, proximal, upper, lower, top, bottom, lateral, front, rear, left, right, etc., are only used to describe the components of appliance 100 relative to each other. Relative position, and is not intended to go any further Ways to limit the invention.

The head 120 generally includes a front surface 124 and a rear surface 125. The front surface 124 and the rear surface 125 of the head 120 can assume a variety of shapes and contours without limiting the invention. For example, the front and rear surfaces 124, 125 can be planar, contoured, or a combination thereof. Front surface 124 and rear surface 125 are joined by a surrounding or lateral surface 126 of head 120.

A plurality of tooth cleaning elements 130, generally shown as a block, are disposed on and extend outwardly from the front surface 124 of the head 120 for cleaning contact with an oral surface, preferably a contact of the teeth. While the set of cleaning elements 130 is particularly suitable for brushing teeth, the set of cleaning elements 130 can also be used to clean replacement teeth or soft tissues other than teeth, such as the tongue, gums or cheeks. As used herein, the term "cleaning element" is used in the generic sense to mean any structure that can be used to clean or massage an oral surface (eg, a tooth or soft tissue) via associated surface contact.

In the present embodiment, a plurality of cleaning elements 130 are provided. However, in a variation with respect to this embodiment, only one cleaning element 130 is provided. Also, in the present embodiment, the cleaning element 130 includes a plurality of bristles.

Wool (or other components, such as synthetic rubber components) Extend through the board or film. The free distal end 131 of the bristles 130 on one side of the plate or film performs a cleaning function. The ends of the bristles 130 on the other side of the plate or film are melted together by heat to be held in place. Any suitable form of cleaning element 130 can be utilized in the broad manner of the present invention. Alternatively, the cleaning element 130 can be mounted to the tuft block or section by extending through an appropriate opening in the tuft block, such that the base of the cleaning element 130 can be mounted within or below the tuft block . An alternative is to use a staple technology.

Regardless of the type and number of cleaning elements 130 provided, the or each cleaning element 130 has its distal end 131 that is furthest from the front surface 124 of the head 120. As shown in FIG. 1, at least one cleaning element 130 extends from the front surface 124 of the head 120 such that the longitudinal axis A-A of the appliance 100 passes through this, some or each cleaning element 130. For each of the cleaning elements 130 through which the longitudinal axis A-A passes, the axis A-A passes through the cleaning element 130 at a point on the cleaning element 130 between the front surface 124 of the head 120 and the free distal end 131 of the cleaning element 130. The importance of this feature is explained below.

If desired, the head 120 posterior surface 125 can include one or more structures for oral cleaning, such as one or more soft tissue cleaners (as shown in Figures 8(b) through 8(d)). The soft tissue cleaner can be constructed from a Thermoplastic Elastomer ("TPE") and can include one or more protrusions (eg, nubs and/or ridges) for Join and massage a soft oral tissue such as the tongue.

In addition to the body 140, the grip 110 of the appliance 100 of the present embodiment includes a gripping structure 150 or "grip". The gripping structure 150 forms a portion of the outer surface 111 of the grip 110 and includes a plurality of projections 158, such as one or more knobs, ridges, ridges, and ribs. The raised portion 158 provides a textured surface for the gripping structure 150 that assists a user in grasping and manipulating the appliance 100 during an oral care event.

In the present embodiment, the grip structure 150 is composed of only one part. Yu Shishi In the embodiment, the grip structure 150 is constructed of an elastic material comprising a thermoplastic elastomer. In other embodiments, the elastomeric material may replace or also include styrene-ethylene/butylene-styrene (SEBS). In still further embodiments, the grip structure 150 may alternatively or alternatively be constructed from one or more rigid or rigid materials such as hard plastic. The rigid or rigid material may comprise any one or more of the following: polyethylene, polypropylene, polyamide, polyester, cellulose, styrene-acrylonitrile (SAN), acrylic, acrylonitrile butadiene styrene (ABS) ) and a thermoplastic plastic. For example, as shown in FIG. 3 (discussed in more detail below), a second embodiment of an oral care implement 100 in accordance with the present invention includes a grip structure 150 having a first part or portion 151 and a first Two parts or portions 152, the first part 151 is constructed of an elastic material (which in the second embodiment is a thermoplastic elastomer), and the second part 152 is connected to the first part 151 and is made of hard or The rigid material (which in the second embodiment is constructed of a hard plastic such as polypropylene).

Returning to the first embodiment of Figures 1 and 2, the grip structure 150 includes a sleeve having an interior surface 153 that defines an internal cavity of a sleeve. The gripping structure 150 is disposed opposite the body 140 such that the first component 145 of a body 140 is disposed within the interior cavity of the sleeve. The inner surface 153 of the grip structure 150 and the outer surface 143 of the first component 145 of a body 140 are sized to allow the grip structure 150 to move relative to the body 140. That is, a gap existing in the form of an annular gap is provided between the inner surface 153 and the outer surface 143. In the present embodiment, the inner surface 153 of the grip structure 150 and the outer surface 143 of the portion of the body 140 are both cylindrical, and the inner surface 153 has a diameter slightly larger than the diameter of the outer surface 143.

The grip structure 150 is attached or mounted to the body 140 and is rotatable relative to the body 140. Additionally, the gripping structure 150 is attached or mounted to the body 140 and is rotatable relative to the head 120, thereby being rotatable relative to the cleaning element 130. The grip structure 150 is about the longitudinal axis A-A of the oral care implement 100 relative to the body 140 and the phase The head 120 is rotatable. In the present embodiment, the grip structure 150 is rotatable relative to the body 140 and relative to the head 120 about the longitudinal axis A-A by 360 degrees (and, above 360 degrees). In addition, the grip structure 150 is free to rotate relative to the body 140 and relative to the head 120 about the longitudinal axis A-A. That is, the rotation of the gripping structure 150 relative to the body 140 and relative to the head 120 is not limited to any other components of the appliance 100. Thus, for example, the gripping structure 150 is not biased relative to the body 140 or A specific angular position relative to the head 120.

The rotation of the gripping structure 150 relative to the head 120 is shown in FIG. The alternate position of the head 120 relative to one of the gripping structures 150 is shown in phantom, which is reached after a relative rotational movement between the head 120 and the gripping structure 150. This relative rotation is further shown in Figures 8(a) through 8(d). In each of Figures 8(a) through 8(d), the grip structure 150 is located at the same position relative to the page, but the head 120 (and the body 140) is rotated 90 degrees between successive images. In an embodiment of the implement 100 other than the body 140, the skilled person will be able to understand similar relative rotational movement between the head 120 and the grip structure 150 (e.g., discussed in the fifth embodiment below).

The body 140 of the appliance 100 of the present embodiment includes a first component 141 and a second component 142. The first component 141 includes a first portion 145 of the body 140 having an outer surface 143 as discussed above. The two components 141, 142 are two parts of the body 140 that are joined together, although in a variation with respect to this embodiment, the two components 141, 142 may be a single, unitary component. The first member 141 has a surface 141a that is not parallel to the longitudinal axis A-A, and the first axial end 150a of a gripping structure 150 abuts against the surface 141a. The second portion 146 of the first member 141 is not disposed within the inner cavity of the gripping structure 150 by the first axial end 150a of the gripping structure 150 adjacent the surface 141a of the first member 141, but instead Extending from the second axial end 150b of a gripping structure 150. The second component 142 of the body 140 is by any means (eg, adhesive, solder, bond, snap connection, mating screw threads) And connected to the first component 141 of the body 140. The second member 142 has a surface 142a that is not parallel to the longitudinal axis A-A, and the second axial end 150b of the gripping structure 150 abuts against the surface 142a. Therefore, the grip structure 150 is disposed between the two components 141, 142 of the body 140, so that the grip structure 150 can be relative to the body 140 and relative to the head by the two components 141, 142 of the body 140. The portion 120 is axially fixed.

In a variation on the illustrated embodiment, the axial length of the gripping structure 150 can be slightly shorter than the axial distance between the surface 141a of the first component 141 and the surface 142a of the second component 142, which can be in the gripping structure 150. When the second axial end 150b abuts the surface 142a of the second component 142, the first axial end 150a of the gripping structure 150 cannot simultaneously abut the surface 141a of the first component 141, thereby allowing the gripping structure 150 to be opposite to the body 140. A small amount of axial movement. Preferably, the axial length of the gripping structure 150 is at least 90% of the axial distance between the surface 141a of the first component 141 and the surface 142a of the second component 142. More preferably, the axial length of the gripping structure 150 is at least 95% of the axial distance between the surface 141a of the first component 141 and the surface 142a of the second component 142.

In a variation with respect to the first embodiment shown, the gripping structure 150 is coupled to the body 140 by a snap connection while still being free to rotate about the axis AA relative to the body 140 and the head 120. .

As described above, the gripping structure 150 is free to rotate relative to the head 120 about the longitudinal axis A-A relative to the cleaning element 130. Moreover, as discussed above, at least one cleaning element 130 extends from the front surface 124 of the head 120 such that the longitudinal axis A-A of the appliance 100 passes through this, some or each cleaning element 130. For each of the cleaning elements 130 through which the longitudinal axis A-A passes, the axis A-A passes through the cleaning element 130 at a point on the cleaning element 130 between the front surface 124 of the head 120 and the free distal end 131 of the cleaning element 130. Thus, the oral care implement 100 has an "oral surface self-tracking function" during use of an oral health care activity. That is, when the cleaning element is moved across the tooth, soft tissue or another oral surface, the head The portion 120 and the cleaning elements rotate relative to the gripping structure 150 to follow the oral surface without requiring the user to change their grip on the gripping structure 150. Thus, where the user does not need to move the surface of their hands and/or fingers relative to the outer surface of the gripping structure 150, the cleaning element 130 is free to follow the contours and relief of the surface of the surface being cleaned. This provides improved cleaning of the user's mouth because it more ensures that the cleaning elements 130 on the head 120 of the appliance 100 can reach and contact the oral surface to be cleaned.

In the present embodiment, the point on the cleaning element 130 through which the axis A-A passes is located between a distal end 131 and the front surface 124 of the head 120. For at least some of the cleaning elements 130, this may be located at each distal end 131 of the cleaning elements 130, which may further ensure that the distal end 131 of the cleaning elements 130 tracks the surface of the oral cavity being cleaned. For one or more other cleaning elements 130, this point is spaced from the respective distal ends 131 of the cleaning elements 130, which may further ensure that the cleaning elements 130 apply a force to the surface of the surface being cleaned, particularly if the cleaning elements 130 Flexible. In any event, this point is preferably closer to the distal end 131 of the cleaning element 130 than the front surface 124 of the head 120.

As described above, the oral care system of the first embodiment further includes a lock. The latching element 200 is moveable between a first state and a second state, as will be explained in more detail below. In Figures 1 and 2, the locking element 200 is attached to the oral care implement 100 in a first position on an oral care implement 100, the first position being the first state of being locked. More particularly, the latching element 200 is mounted to the second component 142 of the body 140 of the grip 110 that is not rotatable relative to the head 120. The latching member 200 includes an inner projection 201 that engages a recess in the outer surface of the second member 142 of the grip 140 to prevent the latching member 200 from rotating about the axis A-A relative to the head 120. When the latch is in the first state (ie, the latching member 200 is in the first position shown in FIGS. 1 and 2), the gripping structure 150 is relative to the head 120. Rotate freely about axis A-A, as described above.

However, by gripping the outer surface 211 of the latching member 200, a user can cause the latching member 200 to face the direction toward the head 120 and parallel to the axis AA, from the first on the oral care implement 100. The position is moved to a second position for placing the buckle in its second state. This movement is relative to the grip 110, the body 140, the gripping structure 150, and the head 120. When the locking component 200 is in the second position (ie, the locking buckle is in its second state), the convex portion 201 located inside the locking component 200 engages the groove in the second component 142 and is formed in the grip Both of the grooves 159 in the outer surface of the structure 150 are held to avoid rotation of the gripping structure 150 relative to the head 120. That is, the latching element 200 prevents the gripping structure 150 from rotating relative to the head 120.

The user then moves the latching element 200 from its second position to its first position, thereby removing the tab 201 from the recess 159 and allowing the gripping structure 150 to freely rotate relative to the head 120.

Figure 8 (a) shows the latching element 200 in its second position, while Figures 8 (b) through 8 (d) show the latching element 200 in its first position, thereby allowing the head 120 and the gripping structure 150 The relative free rotation.

The oral care system of the first embodiment can be manufactured as follows. As a first step, the body 120 of the head 120 and the grip 110 is provided. During manufacture, they can be formed together into a single, unitary part, for example, using an injection molding process, a milling process, and/or a machining process. Alternatively, the head 120 and the body 140 may initially be formed into two separate parts, for example, by an injection molding process, a milling process, and/or a machining process, and then in a subsequent process stage, by Any suitable technique known in the art, including but not limited to thermal welding, sonic welding, a close fitting assembly, a coupling sleeve, an adhesive, a snap and a snap connection, are connected to one another.

As a second step, the head 120 is provided with at least one cleaning element 130, Extending from the front surface 124 of the head 120. This can be by any of the techniques discussed above, such as through AFT, through the use of a shackle, or other techniques. Each of the at least one cleaning element 130 or the at least one cleaning element 130 can take any of the forms discussed above, such as a tooth cleaning element, a soft tissue cleaning element, a bristles, a synthetic rubber element, and the like.

As a later third step, the gripping structure 150 (including the recess 159) is optionally disposed and coupled to the body 140 by a snap connection, relative to the longitudinal axis AA of the appliance 100 The body 140 is free to rotate and the grip structure 150 forms at least a portion of the outer surface 111 of the grip 110. As described above, the axis A-A passes through at least one cleaning element 130 at a point on the cleaning element 130 between the front surface 124 of the head 120 and the distal end 131 of the cleaning element 130. The grip structure 150 is disposed between the two members 141, 142 of the body 140 such that the grip structure 150 is axially fixed relative to the body 140 and the head 120 by the two members 141, 142. That is, the sleeve of the gripping structure 150 is slid over the body 140 such that the first component 145 of the body 140 is positioned within the interior cavity of the sleeve. The second component 142 of the body is then coupled to the first component 141 of the body by any of the mechanisms discussed above such that the gripping structure 150 can be trapped between the two components 141, 142. The grip structure 150 can be provided by using any of an injection molding process, a milling process, and/or a machining process.

In a variation on this method, the third step can be performed before or in conjunction with the second step.

Finally, the buckle is provided by attaching the locking element 200 to the appliance 100 due to the first position or the second position.

A second embodiment of the present invention will now be described with reference to FIG. The second embodiment includes all of the above-described elements of the first embodiment of the present invention, and the same elements are denoted in FIG. 3 by the same reference numerals as used in FIGS. 1 and 2. For simplicity, two implementations Common elements of the example will not be described in detail with reference to FIG. 3. All of the above possible variations with respect to the first embodiment are equally applicable to the second embodiment.

The oral care implement 100 of the system of the second embodiment differs from the implement 100 of the first embodiment only in the form and configuration of the grip structure 150. In the first embodiment, the grip structure 150 is composed of only one part. In the second embodiment, the grip structure is composed of two or more parts joined together. More specifically, the holding structure 150 has a first part 151 and a second part 152, and the first part 151 is constructed of an elastic material such as a thermoplastic elastomer and/or SEBS, and the second part 152 is constructed of a rigid or rigid material (in this case a hard plastic such as polypropylene). The rigid or rigid material may alternatively or additionally comprise any of the plastics discussed above.

The first part 151 forms an outer surface of a majority of the grip structure 150. In a variation on this embodiment, the first part 151 can form all of the outer surfaces of the grip structure 150. A plurality of such first parts 151 may be provided, each of the first parts 151 being coupled to the second part 152. In such variations, the first features 151 can each include a protrusion (eg, a knob, ridge, ridge, or rib) from the second component to assist a user in grasping the grip structure 150. on.

The grip structure 150 is coupled to the body 140 via a second part 152 that is coupled to or mounted to the body 140. The first part 151 is not directly connected to the body 140, but is only indirectly connected to the body 140 through the second part 152. The grip structure 150 is disposed between the two components 141, 142 of the body 140, as described above with respect to the first embodiment. Because both the body 140 and the second part 152 of the grip structure are composed of a hard material, the grip structure 150 can be freely rotated relative to the body 140, wherein the body 140 and the second part 152 are mutually contact. However, because the first part 151 is constructed of an elastic material, the grip structure 150 has a comfortable outer surface for gripping. Preferably, the outer surface of the first part 151 The coefficient of friction is greater than the coefficient of friction of the inner surface 153 of the second part 152.

The locking element 200 of the system of the second embodiment is substantially identical to the locking element 200 of the first embodiment except that the recess 159 is formed only in the first part 151 of the gripping structure 150. In a variation on this embodiment, the groove 159 can extend through both the first and second parts 151, 152 of the grip structure 150.

The oral care system of the second embodiment can be manufactured substantially in accordance with the above-described manufacturing method of the first embodiment, the only difference being the manner in which the grip structure 150 is provided. According to a second embodiment, the grip structure 150 is formed by first forming a second part 152 of hard material, such as via an injection molding process, a milling process, and/or a machining process. The second part 152 can be symmetrical about rotation and preferably has cylindrical symmetry. The material of the first part 151 is then molded onto the second part 152, for example by plastic injection molding. Further, a groove 159 is formed in one or both of the first and second parts 151, 152.

A third embodiment of the present invention will now be described with reference to FIG. The third embodiment includes the above-described elements of the first embodiment of the present invention, and the same elements are denoted by the same reference numerals as those used in FIGS. 1 and 2 in FIG. For the sake of brevity, elements common to both embodiments will not be described in detail with reference to FIG. All of the above possible variations with respect to the first and second embodiments are equally applicable to the third embodiment.

In the third embodiment, the grip 110 still includes a body 140 and a gripping structure 150, but the body 140 does not have a component that is equivalent to the second component 142. The body 140 is constructed of only one component 141 and is constructed of a rigid or rigid material such as a rigid plastic. A member 145 of a body 140 includes a sleeve having an interior surface 146 defining an internal cavity of a sleeve, and a first portion 155 of a gripping structure 150 is disposed within the sleeve. Inside. The second portion 157 of a gripping structure 150 includes an outer surface for a user to grip, the outer surface of which forms a portion of the outer surface 111 of the grip 110.

The inner surface 146 of the body 140 and the outer surface 156 of the first portion 155 of the gripping structure 150 are sized to allow the gripping structure 150 to move relative to the body 140. That is, a gap existing in the form of an annular gap is disposed between the inner surface 146 and the outer surface 156. In the present embodiment, both the inner surface 146 of the body 140 and the outer surface 156 of the first portion 155 of the gripping structure 150 are cylindrical, the inner surface 146 having a diameter that is slightly larger than the diameter of the outer surface 156.

The grip structure 150 is coupled to the body 140 via a snap connection between the grip structure 150 and the body 140 (more specifically between the second part 152 of the grip structure 150 and the body 140). However, in various variations with respect to this embodiment, other forms of connections may be used. The grip structure 150 is free to rotate relative to the body 140. In addition, the gripping structure 150 is attached or mounted to the body 140, and is rotatable relative to the head 120, thereby being free to rotate relative to the cleaning element 130. The grip structure 150 is free to rotate relative to the body 140 and relative to the head 120 about the longitudinal axis A-A of the oral care implement 100.

In the third embodiment, the grip structure 150 is constructed of two parts 151, 152 that are joined together. More specifically, the holding structure 150 has a first part 151 and a second part 152, and the first part 151 is constructed of an elastic material such as a thermoplastic elastomer and/or SEBS, and the second part 152 is constructed of a rigid or rigid material (in this case a hard plastic such as polypropylene). The rigid or rigid material may alternatively or additionally comprise any of the plastics discussed above.

The first part 151 forms an outer surface of a majority of the grip structure 150. In a variation on this embodiment, the first part 151 can form all of the outer surfaces of the grip structure 150. The grip structure 150 is coupled to the body 140 via a second part 152 that is coupled to or mounted to the body 140. The first part 151 is not directly connected to the body 140, but is only indirectly connected to the body 140 through the second part 152. Because both the body 140 and the second part 152 of the grip structure are made of a hard material The composition is such that the grip structure 150 can be easily rotated relative to the body 140 in the case where the body 140 and the second part 152 are in contact with each other. However, because the first part 151 is constructed of an elastic material, the grip structure 150 has a comfortable outer surface for gripping. Preferably, the coefficient of friction of the outer surface of the first part 151 is greater than the coefficient of friction of the outer surface 156 of the second part 152.

In a variation with respect to the third embodiment shown, the gripping structure 150 can be constructed from only one piece and can be used with any of the above discussed ones for the gripping structures 150 of the first and second embodiments. A variety of materials are constructed.

The oral care system of the third embodiment further includes a buckle that includes a locking element 200. In FIG. 4, the locking element 200 is attached to the oral care implement 100 in a first position on an oral care implement 100, which is in a locked first state. More particularly, the locking element 200 is mounted to the gripping structure 150 that is rotatable relative to the head 120. The latching member 200 includes an inner projection 201 that engages a recess in the outer surface of the gripping structure 150 to prevent the latching member 200 from rotating about the axis A-A relative to the gripping structure 150. When the latch is in the first state (ie, the latching member 200 is in the first position shown in FIG. 4), the gripping structure 150 is free to rotate about the axis AA with respect to the head 120. As mentioned above.

However, by gripping the outer surface 211 of the latching member 200, a user can move the latching member 200 from a first position on the oral care implement 100 toward a head 120 and parallel to the axis AA. To a second position for placing the buckle in its second state. This movement is relative to the grip 110, the body 140, the gripping structure 150, and the head 120. When the locking component 200 is in the second position (ie, the locking buckle is in the second state thereof), the convex portion 201 located inside the locking component 200 engages the groove in the holding structure 150 and is formed on the body Both of the grooves 149 in the outer surface of 140 are not rotatable relative to the head 120. Thus, the grip structure 150 becomes free from rotation relative to the head 120. That is, the latching member 200 avoids gripping the structure 150 For the head 120 to rotate.

Next, the user can move the latching element 200 from its second position to its first position, thereby removing the tab 201 from the recess 149 and allowing the gripping structure 150 to freely rotate relative to the head 120. The oral care system of the third embodiment can be manufactured substantially in accordance with the above-described manufacturing method of the second embodiment, the only difference being the manner in which the gripping structure 150 is coupled to the body 140. According to a second embodiment, a portion of the body 140 is disposed within a sleeve of a gripping structure 150. Conversely, in the third embodiment, the first portion 155 of the gripping structure 150 is disposed within the sleeve of the body 140 and is optionally coupled to the body 140 by a snap connection. Further, in the third embodiment, the recess 159 is disposed at an end of the grip structure 150 of the first member 141 of the body 140. In the third embodiment, the buckle is provided by attaching the locking element 200 to the appliance 100 due to the first position or the second position.

A fourth embodiment of the present invention will now be described with reference to FIG. The fourth embodiment includes a plurality of the above-described elements of the second embodiment of the present invention, and the same elements are denoted by the same reference numerals as those used in FIG. 3 in FIG. For the sake of brevity, elements common to both embodiments will not be described in detail with reference to FIG. All of the above possible variations with respect to the first to third embodiments are equally applicable to the fourth embodiment.

In the fourth embodiment, the grip 110 still includes a body 140 and a gripping structure 150, but the body 140 does not have a component equivalent to the second component 142 as compared to the second embodiment. The body 140 is constructed of only one component 141 and is constructed of a rigid or rigid material such as a rigid plastic.

Regarding the second embodiment, the grip structure 150 has two parts 151, 152. The first part 151 is constructed of an elastic material such as a thermoplastic elastomer and/or SEBS, and the second part 152 is constructed of a rigid or rigid material (in this case a hard plastic such as polypropylene). . The rigid or rigid material may alternatively or additionally comprise any of the plastics discussed above. The first part 151 forms the grip structure 150 Most of the exterior surfaces. In a variation with respect to this embodiment, the first part 151 can only form all of the outer surfaces of the grip structure 150. The grip structure 150 is coupled to the body 140 via a second part 152 that is coupled to or mounted to the body 140. The first part 151 is not directly connected to the body 140, but is only indirectly connected to the body 140 through the second part 152. Because both the body 140 and the second component 152 of the gripping structure are comprised of a hard material, the gripping structure 150 can be easily rotated relative to the body 140 with the body 140 and the second component 152 in contact with one another. However, because the first part 151 is constructed of an elastic material, the grip structure 150 has a comfortable outer surface for gripping. Preferably, the coefficient of friction of the outer surface of the first part 151 is greater than the coefficient of friction of the inner surface 153 of the second part 152.

The grip structure 150 is coupled to the body 140 via a snap connection between the grip structure 150 and the body 140 (more specifically between the second part 152 of the grip structure 150 and the body 140). However, in various variations with respect to this embodiment, other forms of connections may be used. The grip structure 150 is free to rotate relative to the body 140. In addition, the gripping structure 150 is attached or mounted to the body 140 and is rotatably free relative to the head 120 relative to the cleaning element 130. The grip structure 150 is free to rotate relative to the body 140 and relative to the head 120 about the longitudinal axis A-A of the oral care implement 100.

In a variation with respect to the fourth embodiment shown, the gripping structure 150 can be constructed from only one piece and can be used with the gripping structures 150 of the first, second and third embodiments discussed above. Any one or more materials are constructed.

The oral care system of the fourth embodiment further includes a buckle that includes a locking element 200. In FIG. 5, the locking element 200 is attached to the oral care implement 100 in a first position on an oral care implement 100, which is in a locked first state. More particularly, the latching element 200 is mounted to the first component 141 of the body 140 of the grip that is not rotatable relative to the head 120. The locking component 200 includes an inner protrusion 201. It engages a recess in the outer surface of the first member 141 of the body to prevent the latching member 200 from rotating about the axis A-A relative to the head 120. When the latch is in the first state (ie, the latching member 200 is in the first position shown in FIG. 5), the gripping structure 150 is free to rotate about the axis AA with respect to the head 120. As mentioned above.

However, by holding the outer surface 211 of the latching member 200, a user can cause the latching member 200 to face the first position on the oral care implement 100 in a direction toward the head 120 and parallel to the axis AA. Move to a second position to place the buckle in its second state. This movement is relative to the grip 110, the body 140, the gripping structure 150, and the head 120. When the locking component 200 is in the second position (ie, the locking buckle is in its second state), the convex portion 201 located inside the locking component 200 engages the groove in the first component 141, and is formed on Both of the grooves 159 in the outer surface of the structure 150 are gripped to avoid rotation of the gripping structure 150 relative to the head 120. That is, the latching element 200 prevents the gripping structure 150 from rotating relative to the head 120.

Next, the user can move the latching element 200 from its second position to its first position, thereby removing the tab 201 from the recess 159 and allowing the gripping structure 150 to freely rotate relative to the head 120.

The oral care system of the fourth embodiment can be manufactured substantially in accordance with the above-described manufacturing method of the second embodiment, the only difference being the manner in which the gripping structure 150 is coupled to the body 140. According to the second embodiment, the grip structure 150 is configured or trapped between the two components 141, 142 of the body 140. Conversely, in the fourth embodiment, the second component 142 of the body is not provided, and the gripping structure 150 is via a snap connection between the gripping structure 150 and the body 140, or via still allowing the gripping structure 150 to be relatively Another suitable connection for rotation of the head 120 and the body 140 is coupled to the body 140. A groove 159 is formed at an end of the grip structure 150 of the first component 141 of the body 140.

In the fourth embodiment, the buckle is provided by attaching the locking element 200 to the appliance 100 due to the first position or the second position.

A fifth embodiment of the present invention will now be described with reference to FIG. The fifth embodiment includes a plurality of the above-described elements of the third embodiment of the present invention, and the same elements are denoted by the same reference numerals as those used in FIG. 4 in FIG. For the sake of brevity, elements common to both embodiments will not be described in detail with reference to FIG. 6. All of the above possible variations with respect to the first to fourth embodiments are equally applicable to the fifth embodiment.

In the fifth embodiment, the grip 110 no longer has a component that is comparable to the body 140. The grip 110 is constructed solely of the grip structure 150 that is rotatably coupled to the head 120. The head 120 includes a sleeve having an interior surface 127 defining an internal cavity of a sleeve and a first portion 155 of a gripping structure 150 disposed within the interior cavity of the sleeve. The second portion 157 of a gripping structure 150 includes an outer surface for a user to grip, the outer surface of which forms a portion of the outer surface 111 of the grip 110.

The inner surface 127 of the head 120 and the outer surface 156 of the first portion 155 of a gripping structure 150 are sized to permit the gripping structure 150 to move relative to the head 120. That is, a gap existing in the form of an annular gap is disposed between the inner surface 127 and the outer surface 156. In the present embodiment, the inner surface 127 of the head 120 and the outer surface 156 of the first portion 155 of the gripping structure 150 are cylindrical, and the inner surface 127 has a diameter that is slightly larger than the diameter of the outer surface 156.

The grip structure 150 is coupled to the head 120 via a snap connection between the grip structure 150 and the head 120 (more specifically between the second part 152 of the grip structure 150 and the head 120). However, in various variations with respect to this embodiment, other forms of connections may be used. The grip structure 150 is free to rotate relative to the head 120 about the longitudinal axis A-A of the oral care implement 100, relative to the cleaning element 130.

The grip structure 150 is comprised of two parts 151, 152 that are joined together. More specifically, the grip structure 150 has a first part 151 and a second part 152, the first part 151 being constructed of an elastic material such as a thermoplastic elastomer and/or SEBS, and the second part 152 Constructed from a rigid or rigid material (in this case a hard plastic such as polypropylene). The rigid or rigid material may alternatively or additionally comprise any of the plastics discussed above.

The first part 151 forms an outer surface of a majority of the grip structure 150. In a variation on this embodiment, the first part 151 can form all of the outer surfaces of the grip structure 150. The grip structure 150 is coupled to the head 120 via a second part 152 that is coupled to or mounted to the head 120. The first part 151 is not directly connected to the head 120, but is only indirectly connected to the head 120 through the second part 152. Because both the head 120 and the second part 152 of the gripping structure 150 are comprised of a hard material, the gripping structure 150 can be easily rotated relative to the head 120, wherein the head 120 and the second part 152 are in contact with each other. However, because the first part 151 is constructed of an elastic material, the grip structure 150 has a comfortable outer surface for gripping. Preferably, the coefficient of friction of the outer surface of the first part 151 is greater than the coefficient of friction of the outer surface 156 of the second part 152.

In a variation with respect to the fifth embodiment shown, the gripping structure 150 can be constructed of only one piece and can be used by the gripping structures 150 of the first to fourth embodiments for any of the above discussed or A variety of materials are constructed.

The oral care system of the fifth embodiment further includes a buckle, and the buckle includes a locking member 200.
