    FIELD OF THE INVENTION
    [0001] The present invention relates to an oral cleaning section and refers, in particular, to an oral cleaning section that has a first magazine on which at least one first cleaning element is mounted and a second magazine on which at least a second cleaning element is mounted. BACKGROUND OF THE INVENTION
    [0002] US 2008/0307591 A1 presents as an oral cleaning section a brush section for use with an electric toothbrush. The brush section has a brush head portion that supports a first plurality of contact elements and a movable contact element retainer that supports a second plurality of contact elements. In some embodiments, multiple rows of the first plurality of contact elements are separated by a row or rows of the second plurality of contact elements.
    [0003] Each of the support structures must have a width that allows the assembly of the contact elements without undue rupture or deformation of the support structures, which does not allow a high density of contact elements perpendicular to the row direction, specifically when the rows of contact elements of the first and second plurality of contact elements are arranged alternately.
    [0004] Thus, it is desired to offer an oral cleaning section that allows a high density of the first and second oral cleaning elements and, at the same time, allows a relative movement of the first and second cleaning elements in relation to each other . SUMMARY OF THE INVENTION
    [0005] An oral cleaning section that satisfies the mentioned desire is given according to claim 1. Additional modalities are given by the dependent claims.
    [0006] The oral cleaning section, as proposed, comprises a first loader that has a cleaning side on which at least one first cleaning element is mounted and a second loader that has a cleaning side on which at least one second cleaning element is mounted. At least one opening is provided on the first charger. The second magazine is arranged under the first magazine in relation to the cleaning side of the first magazine (ie, the first and second magazine are arranged on top of each other in such a way that the cleaning side of the first magazine defines the outermost side. of the provision that is intended to face a location of the mouth to be cleaned). In addition, the cleaning side of the second magazine extends laterally beyond the opening, that is, the second magazine overlaps the first magazine at least in a lateral direction, which is possible when the magazine (not just its mounting surfaces) they are arranged under one another. The second cleaning element extends through the opening. The first loader and the second loader are arranged so that they move in relation to each other. As the first loader and the second loader are arranged on top of each other, this allows for the overlap in the wall thickness necessary for mounting the first and second cleaning elements on the first and second loaders, respectively. This leads to a higher density of cleaning elements in the field formed by cleaning elements as the first and second cleaning elements can be closer to each other with the proposed layout than with the known layout of the US document. 2008/0307591 A1. The first and / or the second cleaning element or cleaning elements can be realized in bristles or in tufts of bristles, but this does not mean that the possibility that the cleaning elements can be realized, for example, soft elastomeric cleaning structures.
    [0007] In a modality of the proposed oral cleaning section, the first loader and the second loader are mobilely coupled to each other; for example, the second magazine may have the first magazine as a support to enable relative movement in a low volume embodiment.
    [0008] In another modality of the proposed oral cleaning section, the second loader is arranged so as to perform an oscillatory rubbing movement around a longitudinal axis that is essentially parallel to an axis of longitudinal extension of the oral cleaning section. Thus, in operation, when the oral cleaning section extends to the oral cavity, the second cleaning element or second cleaning elements perform an oscillatory rubbing movement similar to the rubbing movement that a user of a manual toothbrush would use to brush your teeth, but, in the proposed modality, the user does not have to actively move the oral cleaning section.
    [0009] In another embodiment of the proposed oral cleaning section, the oral cleaning section comprises a coupling element for transferring motion induced by a driver to at least one of the first and second loaders.
    [00010] In yet another additional embodiment of the proposed oral cleaning section, the first magazine is arranged so as to at least partially involve the second magazine. The first loader can be used to house the second loader in an internal cavity. In particular, the second carrier may have a second side that is exposed to the rear of the oral cleaning section in such a way that it can come in contact with tissue present in the oral cavity. The second side may have a texture, that is, a roughness or structures suitable for, for example, cleaning the tongue.
    [00011] In this regard, according to one aspect of the invention, an oral cleaning section has a mounting frame and a second magazine that has a cleaning side on which at least one cleaning element is mounted and a second side , opposite the cleaning side, said second side being exposed so that it can come in contact with tissue present in an oral cavity, for example, the tongue, in which case the second side may contain roughness.
    [00012] In yet another modality of the proposed oral cleaning section, at least a first row of first cleaning elements is mounted on the first magazine and at least a second row of second cleaning elements is mounted on the second magazine, with the second row of second cleaning elements extending through the opening. Several openings can be formed in the first magazine in such a way that one of the several second rows of second cleaning elements extends through each of the openings and several first rows of first cleaning elements can be mounted on the first magazine in such a way that the first rows and the second rows are arranged alternately. In such an embodiment, a high density of cleaning elements in a direction perpendicular to the direction of the row extension can be achieved.
    [00013] In an embodiment of the proposed oral cleaning section, the distance between an outer edge of the first cleaning element and an outer edge of the second cleaning element is less than 1.6 mm, for example less than 1.4 mm or less than 1.2 mm and, in particular, the distance can be around 1.0 mm. This can only be achieved if the wall thickness required for assembly overlaps, which is allowed because of the stacked arrangement of the first and second loaders.
    [00014] In another embodiment of the proposed oral cleaning section, a third carrier completes the oral cleaning section at a distal end (the distal end being the end that is located far from a cable section of the oral cleaning device in a coupled state, that is, the proximal end of the cleaning section is the end that is intended to be coupled to the cable section), with the third charger being fixedly connected to the second charger. In such an arrangement, the third loader would perform the same relative movement in relation to the first loader as the second loader; for example, an oscillatory rubbing movement around a longitudinal axis. The specific arrangement of a charger arranged to complete the oral cleaning section can be considered as an innovation in its own right, which is independent of the other features previously discussed. The respective carrier can, in particular, be arranged to carry out an oscillatory rubbing movement around a longitudinal axis that is parallel to the longitudinal extension axis of the oral cleaning section.
    [00015] The oral cleaning section can be realized as a replacement brush head for a removable connection to a handle section of a toothbrush, in particular an electric toothbrush.
    [00016] The invention additionally relates to an oral cleaning device (such as an electric toothbrush or a manual toothbrush) in which an oral cleaning section, as proposed, is used. In case the oral cleaning device is realized as a manual toothbrush, the oral cleaning section can form a single piece with the handle of the manual toothbrush. The oral cleaning device may comprise a section of cable to which the oral cleaning section is removably connected. In a manual toothbrush, provision can be made for an actuator that can be used to move the second charger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION
    [00018] Figure 1A is a side view of an exemplary embodiment of an oral cleaning section 10 as proposed. In the embodiment shown, the oral cleaning section 10 is realized as a removable brush head for removable connection to a cable section of an oral cleaning device (in figure 6 an exemplary oral cleaning device is shown which is realized as a brush electric toothbrush). The oral cleaning section 10 comprises a head portion 100 and a tubular mounting structure 190. The head portion 100 of the oral cleaning section 10 comprises a cleaning element field 101 (embodied therein as a bristle tuft field) extending from the head part 100, essentially in a direction perpendicular to the direction of the longitudinal extension L of the oral cleaning section, as is customary in the art, in order to enable the effective cleaning of an area in the oral cavity such as teeth , the gum, the mucosa or the surface of the tongue. In another embodiment, the oral cleaning section forms a single piece with the handle section of an electric toothbrush (battery operated or rechargeable) or a manual toothbrush.
    [00019] The assembly structure 190 comprises a tube 191 which is slightly tapered towards the head part 100 and is realized to form a single piece with a first loader 110 of the head part 100 of the oral cleaning section 10. The tube 191 has an opening 192 at the end, positioned distally to the part of the head 100, in order to accommodate, for example, a drive rod that extends from the cable section of the oral cleaning device and for the removable assembly of the oral cleaning section on a cable section of an oral cleaning device.
    [00020] The first loader 110 has a cleaning side 113 on which first cleaning elements 111 (realized as tufts of bristles) are mounted, the first cleaning elements 111 forming part of the cleaning element field 101. The first loader 110 forms a single piece with the oral cleaning section 10 and can be manufactured, for example, by a single plastic injection molding process, together with tube 191. The first cleaning elements 111 can be considered as static cleaning elements of the oral cleaning section 10 since they are fixed in relation to the mounting frame 190. When mounted on the cable section of the oral cleaning device, the first charger 110 may not be activated during operation, but may remain static in relation to the 191 tube and the cable section. In another embodiment, the entire cleaning section 10 is additionally activated so that it moves (for example, a reciprocating oscillation in the direction of the longitudinal extension L). The first cleaning elements 111 are still fixed (i.e., static) in relation to the mounting frame 190.
    [00021] The head part 100 additionally comprises a second magazine 120 which is a movable supported part of the oral cleaning section 10 (as will be further discussed with reference to figure 2 and figure 4). The second cleaning elements 121 (also embodied in this as tufts of bristles) are mounted on the cleaning side of the second magazine 120, the second cleaning elements 121 extending through openings 130 formed in the first magazine 110 so whereas the second cleaning elements 121 also form part of the cleaning element field 101 here and are arranged in the immediate vicinity of the first cleaning elements 111. The first and second cleaning elements 111 and 121 form the element field cleaning 101 (here, a field of tuft of bristles) as it is known in relation to the brush heads of electric or manual toothbrushes. When attached to a cable section of an electric oral cleaning device, the second charger 120 can be coupled to the drive shaft of the electric oral cleaning device. During operation, the second loader 120 would then be placed in an oscillatory arc-shaped movement (either with oscillatory rubbing or sweeping movement) around a longitudinal axis that is essentially parallel to the longitudinal extension axis L of the oral cleaning section 10. In operation, the second cleaning elements 121 will then move relative to the first cleaning elements 111 (which, at this point, will remain static in relation to the mounting structure 190). In general, the first loader 110 and the second loader 120 are arranged so as to perform relative movement to each other; consequently, in another embodiment, both the first loader and the second loader are arranged so as to perform relative movement in relation to each other and in relation to the assembly structure. The oscillatory movement of rubbing the second cleaning elements 121 around the longitudinal axis is very similar to the movement that a user would make with a manual oral cleaning device, for example, a manual toothbrush. Consequently, the modality shown of an oral cleaning section 10, as proposed, provides the sensation of a natural movement that may be preferred by some users in contrast to other movements that the brush head can perform.
    [00022] The second magazine 120 has a second side 124 that extends through an opening in the rear side of the head portion 100 (i.e., the first magazine is designed in such a way that it covers the cleaning side of the second magazine 120 and it also partially surrounds the second loader 120 - it can be said that the second loader 120 is at this point partially housed in the first loader 110 - such that the second side 124 of the second loader 120 is exposed). Consequently, in operation, not only the second cleaning elements 121 move in relation to the mounting frame 191, but also the second side 124 of the second magazine 120 moves and thus provides a moving surface over the rear sludge of the part head 100. This can be used, for example, to provide a tongue cleaning structure suitable for cleaning the tongue by making the second side 124 of the second magazine 120 become textured (for example, by making the second side 124 becomes rough or when providing structures on the back side, the texture can be provided by an additional layer of material, for example, an elastomeric material, applied to the second side 124).
    [00023] It should be noted, at this point, that it is considered an invention in itself to provide an oral cleaning section that has a part of the head and at least one loader supported, movably, on the part of the head, being that said mobile loader has a first side on which cleaning elements are mounted and a second side which is exposed on the rear side of the head part, said rear side being opposite to the front side of the head part from which the cleaning elements extend.
    [00024] In the example embodiment shown, the head part 100 additionally comprises a third magazine 150 that completes the distal end of the oral cleaning section 10. The third magazine 150 has a cleaning side on which third cleaning elements 151 (again realized in this as tufts of bristles) are assembled. The extension direction of the third cleaning elements 151 is very inclined (outwardly) in relation to the cleaning side of the oral cleaning section 10, while the extension direction of the first and second cleaning elements 111 and 121 is essentially normal in relation to the cleaning side of the oral cleaning section 10. In the embodiment shown, the third magazine 150 forms a single piece with the second magazine 120. The provision of such a mobile magazine that concludes the distal end of the oral cleaning section and also performing an oscillatory rubbing motion around a longitudinal axis that is essentially parallel to the longitudinal extension axis of the oral cleaning section 10 is an independent innovation in itself and is additionally considered as an ideal resource in the context of the present invention.
    [00025] In the case of the first, second or third cleaning elements 111, 121 or 151, respectively, realized as tufts of bristles, these can be mounted on the first, second or third loaders 110, 120 or 150, respectively, in a manner as it is known in the art, for example, by means of stapling (anchoring), formation of anchor-free tufts (FTIA) or in an internal modeling process. Instead of bristles or tufts of bristles, at least some of the cleaning elements could, for example, be realized as soft, flexible elastomeric fingers in order to massage and gently remove debris from the oral tissue or as thin, flexible flaps in order to clean interdental cavities, etc.
    [00026] Figure 1B is a front view of the cleaning side 113 of the oral cleaning section 10 as shown in figure 1A. The same resources as those already shown in figure 1A have the same reference numerals, with reference to the previous description. In the front view, it can be seen that the first cleaning elements 111 and the second cleaning elements 121 are arranged in alternating rows. The first cleaning elements 111 form first rows 112 of first cleaning elements and the second cleaning elements 121 form second rows 122 of second cleaning elements. In this, the first three rows 112, each having three double bristles, and the three second rows 122, each having two double bristles, are alternately arranged in a longitudinal direction. As shown in this, the rows of cleaning elements can be aligned centrally in their resting position. Consequently, during operation, each row of cleaning elements is alternately placed in an arc-shaped oscillation that occurs in a plane that is essentially perpendicular to the longitudinal extension axis of the oral cleaning section 10. The second cleaning elements 121 are they extend through openings 130 formed in the first loader 110. The openings 130 have a circumferential extension (at this point, the circumferential extension is taken in relation to the longitudinal extension axis L indicated by the dashed dashed line drawn in figure 1B; the opening 130 does not it must be curved around the longitudinal extension axis) which is large enough to allow the arc-shaped oscillation of the second cleaning elements 121, but the axial extension (on the longitudinal extension axis L) is only the width of the axial extension (at this point, the axial extension is the width of the second cleaning elements 121 in the direction of the longitudinal extension) of the second cleaning elements 121 (at this point, realized as tufts of bristles) to enable a high density of cleaning elements in the longitudinal direction (in other words: the chosen design helps to achieve a minimum distance between the first and second rows 112 and 122 in the longitudinal direction, which leads to a high density of cleaning elements in the longitudinal direction; this will be further discussed with reference to figure 3 and figure 4). The density of cleaning elements achieved in the longitudinal direction is greater than the density that could be achieved in the first and second loaders that are arranged side by side instead of one over the other, since the assembly of the cleaning elements as tufts of bristles require a certain thickness of the carrier material between the mounting cavities to prevent the material from breaking (or deforming) during the assembly process (for example, anchoring requires having a wall thickness of about 0.8 mm or more). The present invention proposes to have a first and a second loader 110 and 120 that are arranged on top of each other in relation to the direction of extension of the cleaning elements, so that the first and second loaders can move one in relation to to the other and can both extend laterally, so that they overlap in at least one lateral direction. This makes it possible to overlap the required walls between the mounting cavities, so that, in total, a higher density of cleaning elements is achieved in the longitudinal direction than in a side-by-side (not overlapping) arrangement.
    [00027] It should be noted that the modality shown is just an example. The basic feature related to an aspect of the proposed oral cleaning section depends on the fact that a first loader and a second loader are arranged on top of each other (the first and second loaders thus overlapping laterally). Only a single second cleaning element can be mounted on the cleaning side of the second magazine. The first and / or second cleaning elements can be arranged as individual elements, in rows, in dies, etc. The first and second cleaning elements can be arranged in alternating order or the second cleaning element or second cleaning elements can (m) extend through a single opening formed in the first magazine or through several openings formed in the first loader.
    [00028] Figure 2 is a section in longitudinal cross section through the oral cleaning section 10, as shown in figure 1B, along line A-A. The tube 191 of the mounting frame 190 is essentially hollow and accommodates a tongue 180 for securing the oral cleaning section 10 on the cable section mounting element of an oral cleaning device, and a coupling element 170 for coupling the spindle. actuation of the oral cleaning device to the second loader 120 mobilely supported. The mounting element and the rod of the cable section of the oral cleaning device are inserted into the hollow tube 191 through the opening 192. The coupling element 170 comprises a snap-fit hook 171 having a V-shaped snout fits by pressure into a groove, also in the form of a V, formed on the shaft of the drive shaft in order to establish a removable connection of the coupling element 170 and the shaft. Such a snap-fit hook is described in EP 0 500 537 B1, the description of which is incorporated herein by reference. The tongue 180 has a spring-like element that attaches to the mounting element. The details of the tongue 180 and the insert for coupling 170 are more fully explained in U.S. Patent 6,588,042 and EP 1 023 001 B1, the description of which is incorporated herein by reference. The coupling element 170 is connected to the second loader 120 by means of a coupling rod 163, said coupling rod 163 transferring an induced movement through the driving shaft of the oral cleaning device on the coupling element 170 to the second loader 120, so that an oscillatory rubbing motion of the second loader 120 essentially around a longitudinal axis W defined by the first and second bearing axes 161 and 162 is carried out during operation. The longitudinal axis W defined by the first and second bearing axes 161 and 162 is essentially parallel to the longitudinal extension axis L of the oral cleaning section 10. In the example shown, the second magazine 120 forms a single piece with the third magazine 150, said third loader 150 being consequently also executing said oscillatory rubbing movement during operation. The third magazine 150 is movably supported on the first magazine 110 via the second bearing shaft 162. As explained above, the second cleaning elements 121, which are mounted on the cleaning side 123 of the second magazine 120, extend through openings 130 formed in the first magazine 110 and thus form a high density field of cleaning elements together with the first cleaning elements 111, mounted on the cleaning side 113 (see figure 1 A) of the first magazine 110, in the immediate vicinity of the openings 130. In the example shown, also the third cleaning elements 151 mounted on the cleaning side of the third magazine 150 are part of the field of cleaning elements.
    [00029] In figure 2, it can be seen that the second magazine 120 is disposed under the first magazine 110, that is, the cleaning side 123 of the second magazine 120 is positioned under the second side 114 (being opposite the cleaning side first loader) of the first loader 110, thus enabling a lateral overlap of the first and second loaders 110 and 120.
    [00030] Figure 3 is a front view of the cleaning side 113 of a "bare" part of the head 100 'of the mouth treatment section as shown in figure 1B, but shown here without the cleaning elements assembled. Thus, first mounting holes 119 for mounting the first cleaning elements are visible on the first magazine 110, second mounting holes 129 for mounting the second cleaning elements are visible on the second magazine 120 through the openings 130 formed in the first magazine 110 , and third mounting holes 159 for mounting the third cleaning elements are visible on the third magazine 150. The first mounting holes 119 and the second mounting holes 129 are realized as double tufted holes with a bridge-shaped wall recess in order to improve the density of cleaning elements in the row direction. Mounting holes divided into multiple segments are described in EP 1 138 222 B1, the content of which is included here for reference. The vertical distance d1 (which is the distance between the mounting holes measured in a plane perpendicular to the longitudinal extension axis that coincides with the BB line) between the double holes is, here, about 0.8 mm, which is necessary to ensure, for example, stapling in order to secure the tufts of bristles without the risk of break or strong deformation of the intermediate walls. The total longitudinal distance d between the rows of cleaning elements is here about 1 mm due to the wall thickness of about 0.8 mm between the first mounting holes 119 and the wall of the openings 130 as well as a a short distance of about 0.2 mm between the second mounting holes 129 and the walls of the openings (the last distance allowing for a slight widening of, for example, tufts of bristles extending through the openings 130). In case the second loader 120 is placed side by side with the first loader 110 (whether the loaders are arranged at the same height or one of the loaders undergoes a considerable recess), the minimum wall thickness of about 0.8 mm required for the second loader would add to the 0.8 mm wall thickness required for the first loader, so that a distance of at least about 1.6 mm would result between the rows of cleaning elements. A side-by-side arrangement of a first loader and a second loader is described in EP 2 107 892 A1, the content of which is included here for reference. Consequently, the proposed arrangement of the second magazine 120 arranged under the first magazine 110 makes it possible to increase the density of the cleaning elements in the direction that is perpendicular to the row direction. The distance d between a row of first cleaning elements and a row of second cleaning elements can therefore be less than about 1.6 mm; the distance d may be less than about 1.4 mm; less than about 1.2 mm; and the distance d can be in the range of about 0.8 to 1.0 mm. In general, the distance between cleaning elements arranged on the first magazine and cleaning elements arranged on the second magazine can be approximately as small as the distance between two cleaning elements arranged on only one of the two magazine due to the allowed lateral overlap between the first and second loaders arranged on top of each other.
    [00031] Figure 4 is a section in longitudinal cross section through a frontal section of the "bare" part of the head 100 ', as shown in Figure 3 along the BB line, as shown in Figure 3. The second loader 120 is movably supported on the first loader 110 of the oral cleaning section through the first bearing shaft 161 and the second bearing shaft 162. The front part of the first bearing shaft 161 is attached to the second loader 120. The second bearing shaft bearing 162 extends in the longitudinal direction and is attached to the third loader 150 and is loosely extending to a crevice formed in the first loader 110, so that the second loader 120 (and the third loader 150, forming a single piece with the second loader 120) can (m) rotate around the longitudinal axis W defined by the first bearing axis 161 and the second bearing axis 162. As the cross-section cut crosses the walls between the s second mounting holes, the second mounting holes are not visible. The cut also passes through the bridge walls with recess in the first mounting holes, so that the first mounting holes are not visible either. A third mounting hole 159 is visible in this cross-section. In addition, openings 130 are visible. In the assembled state, the second cleaning elements 121 extend through the openings 130 as shown in figure 2. The second magazine 120 has a second side 124 which is exposed on the rear side of the head part. The second side 124 may be textured, for example, it may be provided with a pattern of elastomeric elements suitable for cleaning the tongue as is well known in the art. As can be seen, the cleaning side 123 of the second loader 120 extends laterally (here: in the longitudinal direction) under the second side 114 of the first loader 110, so that the first and second loaders 110 and 120 overlap in the direction longitudinal.
    [00032] Figure 5 is a stepwise cross section with a cut through the head part of the oral cleaning section along the CC line, as shown in Figure 4. The CC line has stages so that the cut passes through the first mounting holes 119 and second mounting holes 129. The second magazine 120 is partially enclosed (i.e., confined) by the first magazine 110. The second side 124 of the second magazine 120 is exposed on the back side of the head part. so that it can come in contact with the tissue present in the oral cavity, for example, the tongue. In another embodiment, the first magazine is completely enclosing the second magazine (that is, the second magazine is completely housed within the first magazine without the second side of the second magazine being exposed).
    [00033] Figure 6 shows an oral cleaning device 1 realized as an electric toothbrush comprising a handle section 20 and an oral cleaning section 10, as proposed, realized as a removable brush head.
    [00034] The dimensions and values presented in the present invention are not to be understood as being strictly limited to the exact numerical values mentioned. Instead, unless otherwise specified, each of these dimensions is intended to mean both the mentioned value and a functionally equivalent range around that value. For example, a dimension displayed as "40 mm" is intended to mean "about 40 mm".
