## Abstract

A sanitizing system for preventing the spread of harmful germs on food or beverage containers by utilizing a quick and compact UV sanitizing system. The doors of the pass-through chamber allow the customer to insert an un-sanitized container on the entry (“dirty”) side of the system, and the retail employee to remove the sanitized container from the exit (“clean”) side of the system without having to touch any other surface (doors, knobs, handles, etc.) than the container itself. The system utilizes movable UV light sources to minimize the time required for effective sanitizing.

## Claims

### Claim 1

A food or beverage container sanitizing system, comprising:
a housing;
a chamber inside the housing having a top, one or more sides, and a bottom, the chamber being sized, dimensioned, and configured to envelope a food or beverage container;
an access door providing access to the chamber when the access door is in an open state and blocking access to the chamber when the access door is in a closed state;
a rotating base for rotating the food or beverage container within the chamber; and
at least one UV light source disposed on an inner surface of the one or more sides of the chamber and configured to direct UV light at a predetermined intensity level and time duration onto a food or beverage container positioned inside the chamber in such a way as to result in sanitizing of surfaces of the food or beverage container;
wherein when the access door is in the closed state a UV sanitation cycle is initiated using the UV light source and when the UV sanitation cycle is complete, the access door is moved to the open state; and
wherein the housing rotates around the chamber and wherein the access door connected to the housing receives un-sanitized food or beverage container in a first position located on a first side of the chamber and rotates to a second position located on second side of the chamber to provide access to a sanitized food or beverage container.

### Claim 2 (depends on 1)

The sanitizing system of claim 1, wherein the food or beverage container the system is configured to sanitize a reusable food or beverage container.

### Claim 3 (depends on 1)

The sanitizing system of claim 1, further comprising a retrieval door opposite the access door, the retrieval door providing access to the chamber when the retrieval door is in an open state and blocking access to the chamber when the retrieval door is in a closed state.

### Claim 4 (depends on 3)

The sanitizing system of claim 3, wherein the access door is configured to receive an un-sanitized food or beverage container and the retrieval door is configured to allow retrieval of a sanitized food or beverage container after the UV sanitation cycle.

### Claim 5 (depends on 1)

The sanitizing system of claim 1, further comprising a container centering device disposed within the chamber.

### Claim 6 (depends on 5)

The sanitizing system of claim 5, wherein the food or beverage container centering device comprises at least one mechanical arm.

### Claim 7 (depends on 1)

The sanitizing system of claim 1, wherein the at least one UV light source comprises an array of UV lights.

### Claim 8 (depends on 1)

The sanitizing system of claim 1, wherein the at least one UV light source is disposed on an arm that extends into an internal volume of the food or beverage container to sanitize an interior surface of the container.

### Claim 9 (depends on 8)

The sanitizing system of claim 8, wherein the arm is configured to place the UV light source in proximity to the interior surface of the container allowing for effective sanitation at a lower intensity level or time duration.

### Claim 10 (depends on 8)

The sanitizing system of claim 8 wherein the arm is configured to rotate within the internal volume of the container to distribute application of UV light.

### Claim 11 (depends on 1)

The sanitizing system of claim 1, further comprising:
a second chamber inside the housing that is sized, dimensioned, and configured to envelope the food or beverage container;
a second access door providing access to the second chamber when the second access door is in an open state, and blocking access to the second chamber when the second access door is in a closed state; and
at least one UV light source disposed within the second chamber and configured to direct UV light at a predetermined intensity level and time duration onto the food or beverage container positioned inside the second chamber in such a way as to result in sanitizing of surfaces of the food or beverage container;
wherein when the second access door is in the closed state a UV sanitation cycle is initiated using the UV light source and when the UV sanitation cycle is complete, the second access door is moved to the open state.

### Claim 12 (depends on 11)

The sanitizing system of claim 11, wherein the second chamber is configured to operate in an opposite direction of the chamber.

### Claim 13 (depends on 1)

The sanitizing system of claim 1, wherein the access door is locked during the sanitation cycle and unlocked after the sanitation cycle.

### Claim 14 (depends on 1)

The sanitizing system of claim 1, wherein the access door automatically transitions between the closed and open states.

### Claim 15

A method for sanitizing a food or beverage container, the method comprising:
providing a food or beverage container sanitizing system, comprising:
a housing;
a chamber inside the housing having a top, one or more sides, and a bottom, the chamber being sized, dimensioned, and configured to envelope a food or beverage container;
an access door providing access to the chamber when the access door is in an open state and blocking access to the chamber when the access door is in a closed state;
a rotating base for rotating the food or beverage container within the chamber;
at least one UV light source disposed on an inner surface of one or more sides of the chamber and configured to direct UV light at a predetermined intensity level and time duration onto a food or beverage container positioned inside the chamber in such a way as to result in sanitizing of surfaces of the food or beverage container;
wherein when the access door is in the closed state a UV sanitation cycle is initiated using the UV light source and when the UV sanitation cycle is complete, the access door is moved to the open state; and
wherein the housing rotates around the chamber and wherein the access door connected to the housing receives un-sanitized food or beverage container in a first position located on a first side of the chamber and rotates to a second position located on second side of the chamber to provide access to a sanitized food or beverage container;
inserting an un-sanitized food or beverage container into the chamber;
initiating a UV sanitation cycle sanitizing the food or beverage container; and
retrieving a now sanitized food or beverage container from the chamber.
