Abstract

A sterilization apparatus for sterilizing containers, such as plastic water bottles employs ultra violet (UV) light sterilization technology in a portable fashion. The apparatus is a standalone unit that is intended for residential use, is portable, and is specifically configured to receive and treat multiple sized bottles without additional add-ons. The apparatus positions and includes features to hold the bottle in a horizontal position within the housing of the apparatus such that the horizontally oriented UV bulb is disposed within the inside of the bottle.

Claims

1. An apparatus for sterilizing an inside of a container comprising:

a housing having a first part and a second part that define an interior, the first part being movable relative to the second part between an open position and a closed position in which the first and second parts are sealed, the housing including a first end portion that closes off a first end of the housing and is attached to the first part such that the first end portion and the first part move in unison between the open and closed positions, the housing also including a second end portion that closes off a second end of the housing and is attached to the second part and remains in a fixed position in the open and closed positions;

a UV bulb disposed horizontally within the interior and spaced above a floor of the second part;

a first retaining member for holding a neck portion of the container, the first retaining member being disposed about the UV bulb at one end thereof and having a plurality of concentric slots for accommodating different sized neck portions to permit the UV bulb to be received within an interior of the container;

a support disposed along the second part, wherein the first retaining member and support are configured to hold the container in an least substantially horizontal orientation within the interior; and

a power source operatively connected to the UV bulb and to a controller that provides control over the activation of the UV bulb.

2. The apparatus of claim 1, wherein each of the first part and the second part of the housing has a semi-circular shape such that in the closed position, the first and second parts define a cylindrical body.

3. The apparatus of claim 1, wherein the first retaining member comprises a plurality of concentric seal members formed of a resilient material, with one concentric slot being defined a pair of adjacent seal members.

4. The apparatus of claim 3, wherein the seal members are formed of rubber.

5. The apparatus of claim 3, wherein the UV bulb comprises an elongated bulb that is disposed within an inner, centermost seal member.

6. The apparatus of claim 1, wherein each of the first and second end portions comprises an end cap that closes off the housing in the closed position.

7. The apparatus of claim 6, wherein the power source and controller are disposed within the second end portion.

8. The apparatus of claim 1, wherein the first part includes a first sealing edge that seats against and seals relative to a second sealing edge of the second end portion.

9. The apparatus of claim 1, wherein the second part includes a third sealing edge that seats against and seals relative to a fourth sealing edge of the first end portion.

10. The apparatus of claim 1, wherein the support comprises an adjustable riser that supports the bottle and can be locked into one of a plurality of different heights.

11. The apparatus of claim 10, wherein the support comprises a pivotable riser that is pivotally attached to the second section, wherein a top edge of the support comprises an arcuate edge having a concave shape.

12. The apparatus of claim 11, wherein the pivotable riser includes biased locking pins that extend into a pair of openings formed within the second part for locking the riser in place.

13. The apparatus of claim 12, wherein there are a plurality of pairs of openings formed in the second part corresponding to different positions of the riser, wherein the arcuate edge is located at different heights in the different positions.

14. The apparatus of claim 1, wherein the first retaining member comprises a plurality of flexible fingers that define the concentric slots, the flexible fingers being arranged in pairs of opposing flexible fingers, with one pair of the flexible fingers defining one concentric slot.

15. The apparatus of claim 14, wherein each flexible finger comprises a locking flange located at a distal end of the flexible finger.

16. The apparatus of claim 15, wherein the locking flange comprises a T-shaped locking flange for engaging a thread associated with a neck of the bottle.

17. The apparatus of claim 1, wherein the support is movable and can be locked in different positions in which a top edge of the support is at different heights, the different positions of the support corresponding to the different concentric slots such that when the bottle is in one concentric slot, there is a corresponding position for the support to ensure that the bottle remains in a horizontal orientation.

18. The apparatus of claim 1, wherein the UV bulb is positioned for reception within an open neck of the container to allow the UV bulb to be horizontally oriented within the interior of the container.

19. The apparatus of claim 18, wherein a distal end of the UV bulb is disposed between the support and the first retaining member.

20. An apparatus for sterilizing an inside of a container comprising:

a housing having a first part and a second part that define an interior, the first part being movable relative to the second part between an open position and a closed position in which the first and second parts are sealed, the housing including a first end portion that closes off a first end of the housing and is attached to the first part such that the first end portion and the first part move in unison between the open and closed positions, the housing also including a second end portion that closes off a second end of the housing and is attached to the second part and remains in a fixed position in the open and closed positions;

a UV bulb disposed horizontally within the interior and spaced above a floor of the second part;

a first retaining member for holding a neck portion of the container, the first retaining member being disposed about the UV bulb at one end thereof and having a plurality of concentric slots for accommodating different sized neck portions to permit the UV bulb to be received within an interior of the container, wherein the first retaining member comprises a plurality of concentric seal members formed of a resilient material, with one concentric slot being defined a pair of adjacent seal members;

a support disposed along the second part, wherein the first retaining member and support are configured to hold the container in an least substantially horizontal orientation within the interior, wherein the support comprises a pivotable riser that is pivotally attached to the second section, wherein a top edge of the support comprises an arcuate edge having a concave shape; and

a power source operatively connected to the UV bulb and to a controller that provides control over the activation of the UV bulb;

wherein the support is movable and can be locked in different positions in which a top edge of the support is at different heights, the different positions of the support corresponding to the different concentric slots such that when the bottle is in one concentric slot, there is a corresponding position for the support to ensure that the bottle remains in a horizontal orientation.
