Abstract

An oral hygiene implement attachable to a handle of an oral hygiene device is provided. The implement includes a housing; a functional element movably mounted at the housing such that it can be driven into a motion; a motion transmitter element coupled with the functional element; and an adhesive layer provided at the motion transmitter element for adhesively coupling the motion transmitter element with a drive shaft of the handle when being attached.

First claim

The invention claimed is:

1. An oral hygiene implement having a longitudinal axis and attachable to a handle of an oral hygiene device, the implement comprising:
a housing;
a functional element movably mounted at the housing such that it can be driven into a motion;
a motion transmitter element structured for reciprocal linear motion along the longitudinal axis and having a coupling side at its first end that is distal to the functional element, the motion transmitter element being coupled with the functional element; and
an adhesive layer provided at the coupling side of the motion transmitter element for adhesively coupling the motion transmitter element with a drive shaft of the handle when being attached, for a reciprocal linear movement along the longitudinal axis.

2. The oral hygiene implement in accordance with claim 1 , wherein the adhesive layer is realized by a glue layer.

3. The oral hygiene implement in accordance with claim 1 , wherein the adhesive layer is realized by an adhesive tape or strip, in particular a double-sided adhesive tape or strip.

4. The oral hygiene implement in accordance with claim 1 , wherein the adhesive layer has at least one soft core.

5. The oral hygiene implement in accordance with claim 1 , wherein the adhesive layer has a normal tensile strength of at least about 0.15 N/mm 2 .

6. The oral hygiene implement in accordance with claim 1 , wherein the adhesive layer has a normal tensile strength of below about 0.7 N/mm 2 .

7. The oral hygiene implement in accordance with any claim 1 , wherein at least a part of the section of the motion transmitter element at which the adhesive layer is arranged is made from metal such as stainless steel or aluminum.

8. The oral hygiene implement in accordance with claim 1 , wherein at least a part of the section of the motion transmitter element at which the adhesive layer is arranged is made from a plastic material.

9. An oral hygiene device having a longitudinal axis and comprising:
a handle comprising
a housing; and
a drive shaft coupled to a drive;

an oral hygiene implement connected with the handle comprising
a housing;
a functional element movably mounted at the housing such that it can be driven into a motion; and
a motion transmitter element structured for reciprocal linear motion along the longitudinal axis and having a coupling side at its first end that is distal to the functional element, the motion transmitter element being coupled with the functional element; and
a non-destructively separable adhesive layer provided at the coupling side of the motion transmitter element and connecting the drive shaft with the motion transmitter element for a reciprocal linear movement along the longitudinal axis.

10. The oral hygiene device in accordance with claim 9 , wherein the adhesive layer has a higher adhesion force with respect to the motion transmitter element than with respect to the drive shaft.

11. A kit comprising:
at least one oral hygiene implement having a longitudinal axis and comprising a housing, a functional element movably mounted at the housing such that it can be driven into a reciprocal linear motion along the longitudinal axis, and a motion transmitter element structurerd and configured to be coupled with the functional element; and
an adhesive for coupling the functional element and the motion transmitter element for the reciprocal linear motion along the longitudinal axis.

12. The kit in accordance with claim 11 , wherein the adhesive is selected from the group consisting of a packaged fluid, a viscous adhesive, at least one piece of an adhesive tape or strip and combinations thereof.
