Definitions

  • Figure 3 depicts the same toothbrush head as in figure 2, vied in a tilted position.
  • Figure 4 illustrates an example of embodiment of the present invention that prevents unwanted water to penetrate the apertures on a surface of a toothbrush head.
  • the toothbrush head 30 has an elevated portion 35 comprising a cavity in fluid communication with cavity 31 in the toothbrush head 30, which in its turn is in fluid communication with reservoir comprising toothpaste.
  • Apertures 32 are arranged in the elevated part 35 on a surface of said elevated part 35 facing down towards the bottom face of the toothbrush head 30 such that toothpaste may be dispensed in the cavity 34 provided by the bottom surface of the toothbrush head and the elevated part 35.
  • the edges of the elevated part 35 makes up an aperture wherein the toothpaste dispensed through the apertures 32 may trickle out onto the surface of the bottom face of the toothbrush head 30.
  • the edges of the elevated part 35 is by default in sealing contact with the bottom surface of the toothbrush head 30.
  • the elevated part 35 is in itself provided as a flexible part with a tension in the surface of the elevated part 35 providing the sealing effect. That implies that normally no toothpaste may trickle out on to the bottom surface of the toothbrush head 30 from the cavity 34. However, when a force is applied on the toothpaste, the tension in the elevated part 35 may be compensated, allowing a lifting of the edges in sealing contact with the bottom face of the toothbrush head 30, and toothpaste may tickle out of the aperture provide by the edges of the elevated part 35.
  • bristle positioned on the elevated part 35 will be shorter than bristle located on the bottom surface of the toothbrush head 30. That implies a different stiffness of the bristle on these locations which is an advantageous feature of this example of embodiment.
  • the apertures 32 in the elevated element 35 may be arranged in the sidewalls of the elevated element 35.
  • the shutter mechanism will provide the necessary barrier according to the present invention.
  • Another variant of this example of embodiment comprise apertures in the sidewalls of the shutter 36 it self. When the shutter is moved the apertures 32 in the elevated part 35 may be aligned with the apertures in the sidewalls of shutter 36 thereby providing an open passage for fluid or toothpaste to tickle out from the cavity 31. When the shutter is moved again, a barrier is formed since the apertures no longer are aligned.
