Abstract

A combination night light and vaporizer for liquids in which a plug-in electric wall bracket removably receives a throw-away container in the form of a dispensing package containing the vaporizable liquid. An electric lamp in the bracket provides a heat source for vaporizing the liquid in the container as well as the illumination for the night light, the lamp being controlled through an energizing circuit which includes an electric flow path in the vaporizable liquid between spaced electrodes built into the container, and an overriding manually operable switch enables the establishing of a circuit between the electrodes when there is no liquid in the container and it is desired to energize the lamp for use as a night light.

Claims

1. A vaporizer device adapted to be plugged into and supported by an electrical wall outlet, comprising:

a. a supporting bracket structure including;

plug-in connector prongs connectable with the wall outlet, electric heater means comprising an electric lamp having a base portion and a bulb portion, and having an energizing circuit, and spaced electric contact terminals in said energizing circuit;

b. a hollow container for a vaporizable medium, said container being adapted to be removably mounted on said bracket and including;

a closed bottom providing a heat sink operatively positioned with respect to said heater means, and electric contact terminals at the container bottom for mating coaction with the electric contact terminals of the bracket structure, and having connected portions projecting into the container to provide spaced electrodes in the container for completing said energizing circuit through the vaporizable medium; and

c. said bracket and mounted container having confronting surfaces with aligned surface opening recesses in registration, the recess of the bracket mounting The lamp base portion, and the lamp bulb portion extending into the recess of the container.

2. A vaporizer device according to claim 1, wherein the recess of the container is positioned in said heat sink bottom.

3. A vaporizer device adapted to be plugged into and supported by an electrical wall outlet comprising:

a. a supporting bracket structure of L-configuration, including;

plug-in connector prongs carried by one leg of the bracket connectable with the wall outlet, electric heater means having an energizing circuit, and spaced electric contact terminals in said energizing circuit;

b. a hollow container for a vaporizable medium, said container being adapted to be removably mounted on the other leg of said bracket and extending in substantially parallel relation to said one leg, and including;

a closed bottom providing a heat sink operatively positioned with respect to said heater means, and electric contact terminals at the container bottom for mating coaction with the electric contact terminals of the bracket structure, and having connected portions projecting into the container to provide spaced electrodes in the container for completing said energizing circuit through the vaporizable medium.

4. A vaporizer device according to claim 3, wherein the bracket legs have communicating internal cavities, and the energizing circuit includes electric conductors in said cavities having an electric source connection with said plug-in connector prongs.

5. A vaporizer device according to claim 4, wherein the plug-in connector prongs are supported for unitary rotation as a unit to angularly displaced 90* positions, circuit conductors being connected directly to the prongs and leading therefrom into the adjacent cavity substantially in a plane of rotation of said prongs, whereby the conductors may shift in a generally longitudinal direction and rendered free of bending forces.

6. A vaporizer device adapted to be plugged into an supported by an electrical wall outlet, comprising:

a. a supporting bracket structure including;

plug-in connector prongs connectable with the wall outlet, electric heater means comprising an electric lamp having a bulb portion and having an energizing circuit, and spaced electric contact terminals in said energizing circuit;

b. a hollow container for a vaporizable medium, said container being adapted to be removably mounted on said bracket and including;

a closed bottom providing a heat sink and having the lamp bulb portion positioned therein, and electric contact terminals at the container bottom for mating coaction with the electric contact terminals of the bracket structure, and having connected portions projecting into the container to provide spaced electrodes in the container for completing said energizing circuit through the vaporizable medium; and

c. switch means connected between said electrodes, whereby an energizing circuit may be established through the lamp to provide a night light in the absence of a vaporizable medium in the container.

7. As an article of manufacture, a container for dispensing a heat vaporizable medium and being adapted for operative connection and disconnection with a heat generating device, comprising:

a. a cylindrically elongated hollow envelope having a closed bottom providing a heat sink and an open top end closed by a removable cap member;

b. an inwardly spaced perforated top end wall;

c. a disc member engaged with the outer surface of said end wall, and sealing the perforations therein;

d. a pair of exposed electric elements at the bottom portion of said envelope; and

e. a pair of spaced electrodes extending to the interior of the envelope, and respectively being connected with said electric elements.

8. As an article of manufacture, a container for dispensing a heat vaporizable medium and being adapted for operative connection and disconnection with a heat generating device, comprising:

a. a hollow envelope having a closed bottom providing a heat sink and containing an outwardly opening recess for receiving heat generating means of the heat generating device, when the container is connected thereto;

b. a pair of exposed electric elements at the bottom portion of said envelope; and

c. a pair of spaced electrodes extending to the interior of the envelope, and respectively being connected with said electric terminal elements.

9. An article of manufacture according to claim 8, wherein the electrodes are positioned on opposite sides of said recess.

10. An article of manufacture according to claim 8, including a radial passage in the envelope bottom for venting the recess to atmosphere during connection of the container to the heat generating device.
