专利说明:

[001] The present invention relates to an interdental cleaner with a bar-shaped support, which in a final axial area has a cleaning device, and the cleaning device comprises a support cover made of a synthetic material. -soft elastic elastic, and, on the external side, a structure is formed, which presents several fingers with radial components protruding from the cover, which are made of the same material as the cover and are connected in one piece with this covered.
[002] A corresponding interdental cleaner is known from patent document EP 0 932 371 B1. The interdental cleaner described there has a bar-shaped support of a 1st synthetic material, which at its first end has a cable part and at its axially opposite end has a cleaning device in the form of a support cover. The cover consists of a soft elastic synthetic material, for example, a thermoplastic elastomer, and is sprayed on the support. On its external side, the cover has a structure in the form of nodules or fingers extending radially outwards. The user grasps the interdental cleaner on the handle part and introduces the bar-shaped support with the end that supports the cover to an intermediate space of the tooth, and moves the interdental cleaner to and fro, so the intermediate space of the tooth it is cleaned and any adherent particles are loosened.
[003] It has been shown that, with this interdental cleaner, very good cleaning of the intermediate spaces of the tooth is possible, however it is difficult to remove impurities or deposits of very narrow, fine pockets of the denture.
[004] The invention has the task of creating an interdental cleaner of the type mentioned, with which it can also be obtained cleaning in narrow bags and crevices in a reliable way.
[005] This task is solved according to the invention by an interdental cleaner with the characteristics of claim 1. In this case, it is provided that the structure additionally presents to the fingers protruding from the cover with radial components also a bristle edge with several bundles of bristles and / or individual bristles with radial components protruding from the cover, which are formed respectively, by prefabricated bristles, seated on the cover and / or on the support.
[006] In the sense of this requirement, bristles are prefabricated sections of a monofilament or multifilament made of synthetic material, which have a maximum diameter of 0.25mm.
[007] The “axial” concept used in this text refers to the longitudinal axis of the bar-shaped support and thus also to the longitudinal axis of the cover. The “radial” concept refers to a direction corresponding to a direction that passes perpendicular to the axial longitudinal direction.
[008] The fingers and / or bundles of bristles and / or the individual bristles may extend or radially, that is, at a right angle to the longitudinal axis of the interdental cleaner, or also inclined in relation to that axis, which is expressed by through the expression “with radial component”.
[009] In a known way, the cover is preferably sprayed on the bar-shaped support, and can consist of a thermoplastic synthetic material, for example, a thermoplastic elastomer based on SEBS or ethylene-propylene-diene rubber , or another soft synthetic material, for example, silicone. The covering is preferably executed in the form of a glove and has a shape that follows the longitudinal extension of the support in the form of a bar.
[010] Due to the common arrangement of fingers and bristle edge on the outside of the cover, in combination a high cleaning effect can be achieved. The projected fingers, which deform and flex during the introduction of the interdental cleaner in the intermediate space of the tooth, serve, in essence, to clean the surfaces of the intermediate space of the tooth. Due to the small dimensions of the bristles, however, they can also penetrate cracks and narrow intermediate spaces, and clean those spaces that otherwise could not be cleaned with your fingers.
[011] The fingers are connected in one piece with the cover and are made of the same material as that cover. They are manufactured during the manufacture of the interdental cleaner, together with the formation of the cover, preferably in the injection molding process.
[012] The bundles of individual bristles and / or bristles extend radially or at least with a radial direction component outward. In a preferred embodiment of the invention, it is envisaged that the bundles of bristles and / or the individual bristles penetrate the cover completely and are secure in the support. In this case, the bundles of bristles and / or the individual bristles can be fixed or on the support, however it is also possible that the support is made of synthetic material, and the bundles of bristles and / or the individual bristles are partially seated on the support and preferably that they are safe against extraction. For example, this can be achieved by the fact that the bundles of bristles and / or the individual bristles are positioned at least in an injection molding tool, and then are injected with the support material in desired sections, so the bundles of bristles and / or individual bristles are fixed. In this case, the bundles of bristles and / or the individual bristles are secured in the support with closure due to the shape and / or with closure due to the material. Then the cover can be sprayed with soft elastic synthetic material, and at the same time the fingers are formed connected in one piece with the cover.
[013] Various geometric configurations are possible for the arrangement of fingers and edge of bristles or bundles of bristles and / or individual bristles. In a possible embodiment of the invention, it can be envisaged that several bundles of bristles and / or individual bristles are arranged preferably distributed evenly across the circumference of the cover with the formation of a crown of bristles. In the longitudinal direction of the cover, several crowns of bristles arranged in a radial interval may be provided. The bundles of bristles and / or the individual bristles of the crown of bristles can be arranged in the direction of the circumference with reciprocal gap, but it is also possible to arrange the bundles of bristles and / or individual bristles so narrow from each other that the crown of bristles it forms a disk of bristles circulating perpendicular to the axial longitudinal direction of the cover.
[014] In addition, it is possible that at least some of the bundles of bristles are arranged offset from the bundles of adjacent bristles in the longitudinal direction of the interdental cleaner.
[015] In a possible configuration of the invention it can be provided that several fingers are arranged distributed across the circumference with the formation of a crown of fingers. Preferably several crowns of fingers are disposed in the axial direction of the cover at opposite intervals, and in a possible conformation of the invention it can be provided that the crowns of bristles and the crowns of fingers are arranged alternately in the longitudinal direction of the cover.
[016] In addition, it can be provided that at least some of the fingers are arranged offset from the adjacent fingers in the longitudinal direction of the interdental cleaner.
[017] The fingers, which preferably have a conical shape, which is radially reduced outwards, for example, in the form of a circular cone, protrude with their length out of the cover. In a preferred embodiment of the invention it is envisaged that the bundles of bristles and / or individual bristles will have a longer length protruding in such a way that at least some of the bundles of bristles and / or some of the individual bristles protrude radially through the fingers in the radial direction around an M measurement, with the M measurement being in the range of 0.1mm to 1.5mm, preferably in the range of 0.3mm to 0.7mm, and particularly particularly in the range from 0.4mm to 0.6mm.
[018] In another possible configuration of the invention, it can be provided that at least some of the fingers protrude radially through the bundles of bristles and / or individual bristles around a measure N, whereas measure N is located at range of 0.1mm to 1.5mm, preferably in the range of 0.3mm to 0.7mm, and particularly preferably, in the range of 0.4mm to 0.6mm.
[019] The bundles of bristles can be arranged as bundles of isolated bristles, that is, with an interval in relation to the bundles of adjacent bristles. In a possible embodiment of the invention, it is envisaged that at least some of the bundles of bristles and / or individual bristles are arranged in one or several rows of bristles extending in the longitudinal direction of the cover. The bundles of bristles and / or the individual bristles forming a row of bristles are preferably arranged so closely adjacent that a continuous row of bristles is formed without gaps. The rows of bristles can pass in a straight line in the longitudinal direction of the cover, alternatively or in addition to this, however, it can also be envisaged that the rows of bristles will curl in the longitudinal direction of the cover.
[020] The bundles of bristles and / or individual bristles can be arranged independently of the fingers, on the outside of the cover. In an improvement of the invention, however, in an alternative or additional way, it can be provided that at least one of the fingers of a bundle of bristles and / or at least one individual bristle is penetrated. In this case, preferably more than half the length of the individual bristle or the bristles that form the bundle of bristles is arranged inside the fingers and protrudes with its free end out of the finger, preferably at the radially outer end of the finger, that is, from the fingertip out of that finger.
[021] It has been proven to be advantageous if the finger is penetrated by 1 to 4 individual bristles.
[022] In a possible embodiment of the invention, it can be provided that the bundle of bristles and / or the individual bristles at their radially internal end are secured in the support and in particular, are seated on that support. Alternatively, however, it is also possible for the bundle of bristles and / or the individual bristle to radially penetrate the support and protrude on the opposite sides out of that support. In its central area, which is arranged within the support, the bundle of bristles and / or the individual bristle are secured in the support and in particular are seated on that support.
[023] In another possible configuration of the invention it can be provided that the bundle of bristles and / or the individual bristles are shaped in a U-shape or in a V-shape, and are seated with their base section on the support, in such a way that they with their free ends protrude radially in the aforementioned way.
[024] In another possible configuration of the invention, it may be provided that the bundle of bristles and / or the individual bristles are shaped in an L shape and are seated with an L-shaped flap on the support, and protrude from that support with the other flap. in L. In this case, the L-tab seated on the support can extend in the longitudinal direction of the interdental cleaner, that is, in the axial direction, and the other L-tab passes, in essence, perpendicular to the support, that is, radially or tilted in relation to it.
[025] The bristles can be secured in the support with zipper due to the shape or with zipper due to the material. Particularly good support of the bundles of bristles and / or individual bristles is provided when at an axial end of the bundles of bristles and / or the individual bristles a thickening in the form of an enlarged head is formed, which is seated on the support material. A corresponding head can be made by repressing the bundle of bristles and / or individual bristles, possibly with previous heating in a well-known manner.
[026] Other particularities and characteristics of the invention are evident from the following description of examples of execution with reference to the drawing. They are shown:

[043] In figure 17 a sectional view with bundles of L-shaped bristles and
[044] In figure 18, a sectional representation with U-shaped bristle bundles.
[045] Figure 1 shows a perspective representation of an interdental cleaner 10, which has a support 11 in the form of a bar, made of synthetic material, in which at its rear right end, according to figure 1, a section is formed handle 13, on which a user can grab the interdental cleaner 10.
[046] At the left end according to figure 1, the front which is axially opposite the cable section 13, a cleaning device 12 is placed on the support 11 in the form of a bar. This device has a cover 14 of the support 11, and the cover 14 is made of a soft elastic synthetic material, and on its external side it has a structure 19.
[047] Figures 2 to 4 show the particularities of the structure and elements of the cleaning device 12 and the structure 19.
[048] On its external side, the cover 14 has fingers 15 that protrude freely, protruding radially outwards, which are made of the same material as the cover 14, and executed in one piece with this cover, as shown in figure 4 The fingers 15 have the shape of a cone reducing radially outwards (in this case, represented by way of example as a circular cone). In the example shown, 6 fingers are arranged distributed across the circumference of the cover 14, respectively, in a plane that passes perpendicular to the longitudinal axis L of the support 11, and form a crown of fingers 17. As shown in figure 2, in the longitudinal direction axial of the cover 14, several crowns of fingers 17 are provided arranged with an axial gap. Between the adjacent crowns of fingers 17, a crown of fingers 18 is arranged respectively. Each crown of fingers 18 comprises six bundles of bristles 16, which are seated with their radially internal end on the support 11 (see figure 3), penetrate the cover 14 and protrude radially out of that cover. As shown in figure 4, the length protruding freely at least from some bundles of bristles is greater than the length protruding freely from the fingers 15, such that the free ends of the bundles of bristles protrude radially outward through of the fingers 15 around a measure M, which is in the range of 0.1mm to 1.5mm.
[049] Figure 5 shows a representation similar to figure 4, however, here, the fingers exceed the bundles of bristles 16 radially around a measure N. Measure N is in the range of 0.1mm to 1, 5mm, in such a way that the fingers 15 protrude radially outward through the bundles of bristles 16.
[050] As shown in figures 3 and 4, fingers 15 and bundles of bristles 16 are aligned in the direction of the circumference such that, in projection respectively, a bundle of bristles 16 is disposed between two fingers 15 or a finger 15 it is arranged between two bundles of adjacent bristles 16.
[051] Figure 6 shows a 2nd execution example, which differs from the 1st execution example according to figures 1 to 4 in the arrangement and alignment of the bristle edge. According to figure 6, the bristle edge is formed by several rows of bristles 21, extending in the longitudinal direction of the cover 14 or of the bar-shaped support 11, which pass in a straight line in the longitudinal direction of the cover 14, and form a compact “bristle wall” without gaps. According to the example of execution shown, four rows of straight bristles are evenly distributed across the circumference of the cover 14, and between two adjacent rows of bristles in the direction of the circumference, respectively, a row of fingers is arranged 15.
[052] Figure 7 shows an improvement or a variation of the execution according to figure 6, and it differs from this by the fact that the rows of bristles 22 pass in a curl in the longitudinal direction of the cover 14, and with that they involve this covered. Also in this case, between two rows of bristles 22 spaced in the direction of the circumference, a row of fingers 15 is provided, respectively.
[053] Figures 8 to 10 show a 3rd example of execution, which represents an improvement of the example of execution according to figures 1 to 4, and it differs from these in the fact that, the crowns of bristles 18 to from now on they are formed by a large number of individual bristles 20, which are arranged in a tight package, in such a way that the crowns of bristles 18 are made according to the type of a continuous bristle disk, which extend perpendicularly with respect to to the longitudinal axis L of the cover 14 or the support 11.
[054] As shown in figure 9, the individual bristles 20 at their radially inner end are seated on the support material 11 and penetrate the cover 14 and protrude freely out of that cover.
[055] Figure 11 shows an improvement of the execution according to figure 8, and it differs from this by the fact that the crowns of bristles 18 or discs of bristles have a substantially larger dimension in the axial direction of the cover 14 or the support 11, that is, they are substantially thicker and have a thickness s in the range of 0.5mm to 1.0mm.
[056] In the case of the execution examples shown so far, the fingers 15, on the one hand, and the bristle edge, that is, the bundles of bristles 16 or the individual bristles 20, on the other hand, are executed and are supported or kept respectively independent of each other.
[057] Figures 12 and 13 show an example of a different execution of the interdental cleaner according to the invention, in which individual bristles 20 are provided, which penetrate the fingers 15.
[058] The interdental cleaner 10 has the structure mentioned with the support 11 in the form of a bar and the cover 14, which on its external side supports several fingers 15 molded in one piece, protruding radially outwards. As shown in figure 13, each finger 15 is penetrated by two individual bristles 20. At its radially internal end, the individual bristles 20 are seated on the support material 11, and from there they pass radially outward through the fingers 15 and exit at their end radially external, that is, at the fingertip 15 and protrude radially out of that finger. In this way the individual bristles 20 are influenced and the corresponding finger 15 respectively, in a reciprocal way, so that the individual bristles 20 give the finger 15 greater flexural stability and the finger 15 supports the individual bristles 20 through an essential section of its axial length, such that the danger of bending the bristles 20 is reduced.
[059] Figure 14 shows a variation of the execution according to figure 13. Also in this case, two individual bristles 20 extend in the radial direction through the fingers 15, and leave that finger at the outer tip of the finger 15. However, the individual bristles 20 are not secured with their inner end to the support material 11, but pass through the support 11 and a finger 15 disposed on the opposite side, and exit from that finger at its radially outer end. Accordingly, the individual bristles 20 are arranged in a central area within the support, and are maintained in that support.
[060] In the case of the execution examples mentioned above, bundles of bristles 16 and / or individual bristles 20 and / or fingers 15 are arranged in crowns of surrounding fingers. Figure 15 then shows an example of execution, in which the fingers are disposed, respectively, in relation to the adjacent fingers in the axial or longitudinal direction of the interdental cleaner. The same is true for bundles of bristles 16 and / or individual bristles. This way, it is obtained that during the insertion of the interdental cleaner in an intermediate space of the tooth, the fingers 15 come in successive contact with the tooth surface, so the resistance is reduced. The same goes for individual bristles 20.
[061] Figure 16 shows alternative possibilities for fixing a bundle of bristles 16 to the support material 11. In a 1st embodiment shown above in figure 16, at the radially inner end of the bundle of bristles 16 an enlarged head 23 is formed , with which the bundle of bristles 20 is seated on the support material 11, in such a way that a high resistance to extraction in the form of a seal is obtained due to the shape.
[062] According to a 2nd embodiment shown in the center in figure 1, the bundle of bristles 20 is so long that it completely penetrates the material of the support 11, and protrudes out of that bundle on opposite sides.
[063] According to a 3rd execution shown below in figure 16, the bundle of bristles is curved in a V shape, and with the curved base section of the V shape is seated on the support material 11, being that the flaps of the V shape protrude radially. Also in this case, very high extraction security is provided.
[064] Figure 17 shows another execution of the fixation of the bundle of bristles 16. The bundle of bristles 16 is curved in the shape of an L, and an L-shaped flap passes in the longitudinal direction of the interdental cleaner inside the material of the support 11, while the other L-shaped flap passes perpendicular to it, that is, radially in relation to the longitudinal direction of the interdental cleaner and protrudes radially.
[065] According to figure 18, the bundle of bristles 16 is curved in the shape of a U, and has a base section, preferably horizontal, and two flaps protruding from that section. With the base section, the bundle of bristles 16 is seated on the material of the support 11, and is secured in that support, while the two flaps protrude radially.
