Abstract

A toothbrush including a handle extending in a longitudinal direction and including an upper portion and a base. The upper portion includes an insert portion. The base is made of a flexible material and overlaps the insert portion and includes an interior cavity. A light is configured to emit light visible from outside the handle. An activation device is positioned in the interior cavity and is configured to be pressed in a direction transverse to the longitudinal direction to activate the light upon a user pressing the base.

Claims (26)

1. A toothbrush comprising:

a head including a plurality of bristles;

a handle connected to the head, extending in a longitudinal direction;

a base being made of a flexible material overlapping the handle, and having a sidewall with a raised push point for a user to press;

a light configured to emit light visible from outside the handle;

a power source positioned in the toothbrush and configured to supply power to the light; and

an activation device positioned in the toothbrush and configured to be pressed in a direction transverse to the longitudinal direction to activate the light upon the user pressing on the push point of the sidewall of the base.

2. A toothbrush as set forth in claim 1 wherein the activation device comprises a switch positioned in an interior cavity to complete a circuit to cause the light to be activated upon a user pressing on the push point of the sidewall of the base.

3. A toothbrush as set forth in claim 2 wherein the switch is a dome switch.

4. A toothbrush as set forth in claim 2 wherein the switch comprises a first electrical terminal and a second electrical terminal and is configured such that the first electrical terminal contacts the second electrical terminal to complete the circuit when the activation device is pressed.

5. A toothbrush as set forth in claim 1 wherein an interior surface of the base positioned opposite the push point is configured to contact the activation device to press the activation device to activate the light.

6. A toothbrush as set forth in claim 5 wherein the interior surface of the base positioned opposite the push point includes a protrusion configured to contact the activation device.

7. A toothbrush as set forth in claim 1 wherein the light, the power source, and the activation device are coupled to each other to allow the light, the power source, and the activation device to be inserted into an interior cavity of the handle as a unit.

8. A toothbrush as set forth in claim 1 wherein the activation device is configured to be pressed in a direction towards the power source to activate the light upon the user pressing on the sidewall of the base.

9. A toothbrush comprising:

a head including a plurality of bristles;

a handle coupled to the head and extending in a longitudinal direction and including an interior cavity;

a base coupled to the handle and having an interior surface, at least a portion of the base being flexible and defining a push point;

a light positioned in the interior cavity and configured to emit light visible from outside the handle; and

a dome switch positioned in the interior cavity to complete a circuit to cause the light to be activated upon a user pressing the push point in a direction transverse to the longitudinal direction.

10. The toothbrush of claim 9 wherein the push point is a raised portion of the base.

11. The toothbrush of claim 9 further comprising a power source positioned in the interior cavity such that the dome switch is positioned between the power source and the push point.

12. The toothbrush of claim 9 wherein the dome switch comprises a first electrical terminal and a second electrical terminal and is configured such that the first electrical terminal contacts the second electrical terminal to complete the circuit when the dome is pressed.

13. The toothbrush of claim 9 further comprising a suction cup positioned at a bottom of the base.

14. The toothbrush of claim 9 wherein a sidewall of the base is substantially parallel to the longitudinal direction.

15. The toothbrush of claim 9 wherein the push point is capable of being pressed by a human finger.
