Oral hygiene means

Abstract

An oral hygiene means with at least one application unit has a base body, and at least one handle unit which has a base body. The oral hygiene means includes at least one coupling unit for a releasable coupling of the application unit with the handle unit, the coupling unit including a first coupling element which is fixedly connected with the handle unit, and a second coupling element which corresponds to the first coupling element and is fixedly connected with the application unit, wherein the first coupling element delimits at least one orientation groove extending at least substantially along a main extension direction of the handle unit, and the second coupling element includes at least one inside-situated guide ridge extending at least substantially along a main extension direction of the application unit and configured to engage in the orientation groove in a coupled state of the coupling unit.

1 . An oral hygiene means, with at least one application unit which has a base body, and with at least one handle unit, which has a base body,
 further comprising   at least one coupling unit for a releasable coupling of the application unit with the handle unit, the coupling unit comprising a first coupling element which is fixedly connected with the handle unit, and a second coupling element which corresponds to the first coupling element and is fixedly connected with the application unit, wherein the first coupling element delimits at least one orientation groove extending at least substantially along a main extension direction of the handle unit, and the second coupling element comprises at least one inside-situated guide ridge extending at least substantially along a main extension direction of the application unit and configured to engage in the orientation groove in a coupled state of the coupling unit.

         17 . An oral hygiene means with at least one application unit which has a base body, and with at least one handle unit, which has a base body, wherein the handle unit comprises at least one material volume body and at least one substantial hollow-space structure which is at least substantially delimited by the material volume body and which extends at least over a substantial portion of a main extent of the at least one handle unit,
 wherein   the material volume body has at least three recesses, via which the hollow-space structure is connected to an environment in at least one direction respectively.   
     
     
         18 . The oral hygiene means according to  claim 17 ,
 wherein   the directions in which the at least three recesses connect the hollow-space structure to an environment are angled by at least 80° relative to one another, starting from a geometric center point of the hollow-space structure.   
     
     
         19 . The oral hygiene means according to  claim 17 ,
 wherein   the hollow-space structure is completely enclosed by the material volume body in at least one plane parallel to a main extension plane of the handle unit.   
     
     
         20 . The oral hygiene means according to  claim 17 ,
 wherein   the material volume body has at least two at least substantially oval recesses, a first recess being arranged on a front side of the handle unit and a second recess being arranged on a rear side of the handle unit, offset from the first recess along the main extension direction of the handle unit.   
     
     
         21 . The oral hygiene means according to  claim 20 ,
 wherein   the material volume body has at least two at least substantially semi-oval recesses, which are arranged on a front side of the handle unit, the at least substantially semi-oval recesses being arranged along a main extension direction of the handle unit at a level of the second oval recess.   
     
     
         22 . The oral hygiene means according to  claim 21 ,
 wherein   the material volume body has at least two further at least substantially semi-oval recesses, which are arranged on a rear side of the handle unit, the further at least substantially semi-oval recesses being arranged along a main extension direction of the handle unit at a level of the first oval recess.   
     
     
         23 . The oral hygiene means according to  claim 21 ,
 wherein   the at least substantially semi-oval recesses extend at least substantially perpendicularly to a main extension plane of the handle unit, wherein the at least substantially semi-oval recesses do not extend through a middle plane that extends parallel to the main extension plane through a geometric center point of the handle unit.   
     
     
         24 . The oral hygiene means according to  claim 20 ,
 wherein   the at least substantially oval recesses extend at least substantially perpendicularly to a main extension plane of the handle unit, wherein the at least substantially oval recesses extend through a middle plane that extends parallel to the main extension plane through a geometric center point of the handle unit.   
     
     
         25 . The oral hygiene means according to  claim 20 ,
 wherein   there is an imaginary straight line which extends perpendicularly to the main extension plane of the handle unit and which extends, free from an intersection point with the material volume body, through the at least one first oval recess and the at least one second oval recess.   
     
     
         26 . The oral hygiene means according to  claim 21 ,
 wherein   at least two at least substantially semi-oval recesses open into the second oval recess.   
     
     
         27 . The oral hygiene means according to  claim 20 ,
 wherein   the material volume body is sloped towards the first oval recess and forms a thumb-gripping region.   
     
     
         28 . The oral hygiene means according to  claim 17 ,
 wherein   the hollow-space structure is at least approximately completely covered by the material volume body from the front.   
     
     
         29 . The oral hygiene means according to  claim 17 ,
 wherein   the material volume body has in at least one region at least five strand elements, which are spaced apart from one another in a first region of the handle unit and are arranged in a contacting manner in at least one second region of the handle unit.
