Abstract

A solution for disinfecting flowable products, such as liquids, suspensions, creams, colloids, emulsions, powders, and/or the like, as well as accessories and products relating thereto, such as containers, caps, brushes, applicators, and/or the like, using ultraviolet radiation is provided. In an embodiment, an ultraviolet impermeable cap is configured to enclose a volume corresponding to a flowable product. At least one ultraviolet radiation source can be mounted on the cap and be configured to generate ultraviolet radiation for disinfecting the enclosed area. The ultraviolet radiation source can be configured to only generate ultraviolet radiation when the volume is enclosed by the ultraviolet impermeable cap.

Claims

1. An apparatus, comprising:

an ultraviolet radiation containing case configured to enclose a volume corresponding to a flowable product, the case including a first compartment configured to store a first portion of the flowable product and a second compartment configured to store a second portion of the flowable product, wherein one of the first portion or the second portion of the flowable product can be accessed when the case is open;

a rotatable support trunk located within the first compartment;

a plurality of ultraviolet radiation sources mounted on the rotatable support trunk, wherein the plurality of ultraviolet radiation sources are configured to emit radiation onto the first portion of the flowable product;

a cover configured to selectively close and open the case; and

a sensor configured to cause the plurality of ultraviolet radiation sources to turn off when the cover is removed from the case.

2. The apparatus of claim 1, wherein the plurality of ultraviolet radiation sources mounted on the rotatable support trunk are configured to emit radiation onto the flowable product during rotation of the support trunk.

3. The apparatus of claim 1, further comprising a control system configured to control disinfection of the first portion of the flowable product with the plurality of ultraviolet radiation sources.

4. The apparatus of claim 3, wherein the support trunk includes a nob that effectuates rotation of the support trunk within the first compartment of the case.

5. The apparatus of claim 4, wherein the nob is operatively coupled to the control system, the nob automatically rotating the support trunk within the first compartment of the case at the direction of the control system.

6. The apparatus of claim 1, wherein the second portion of the flowable product can be accessed when the case is open, and wherein the cover includes an ultraviolet radiation source to disinfect the second portion of the flowable product in the second compartment of the case.

7. The apparatus of claim 1, further comprising at least one one-way channel to transfer a portion of the flowable product from the first compartment to the second compartment.

8. The apparatus of claim 1, wherein the cover is ultraviolet impermeable.

9. The apparatus of claim 1, further comprising an interconnect positioned between the case and the cover to form an interconnection therebetween.

10. The apparatus of claim 1, further comprising at least one reflector mounted on an interior surface of at least one of:

the case or the cover for reflecting the ultraviolet radiation.

11. An apparatus, comprising:

an ultraviolet radiation containing case configured to enclose a volume corresponding to a flowable product, the case including a first compartment configured to store a first portion of the flowable product and a second compartment configured to store a second portion of the flowable product, wherein one of the first portion or the second portion of the flowable product can be accessed when the case is open;

a rotating auger configured to transfer the flowable product from the first compartment to the second compartment, the rotating auger having a first end extending into the first compartment and a second end extending into the second compartment;

a cover configured to selectively close and open the case; and

at least one ultraviolet radiation source mounted on at least one of;

the case or the cover to generate ultraviolet radiation for disinfecting the flowable product.

12. The apparatus of claim 11, wherein the case includes a separation plate that separates the first compartment from the second compartment.

13. The apparatus of claim 12, wherein the separation plate moves vertically in the case as a function of the rotation of the rotating auger.

14. The apparatus of claim 11, further comprising at least one one-way channel to transfer a portion of the flowable product from the first compartment to the second compartment.

15. The apparatus of claim 14, wherein rotation of the rotating auger pushes portions of the flowable product from the first compartment through the at least one one-way channel into the second compartment.

16. The apparatus of claim 11, further comprising a control system configured to control disinfection of the flowable product with the at least one ultraviolet radiation source.

17. The apparatus of claim 16, further comprising at least one sensor to obtain attribute information regarding biological activity in the flowable product, the control system controlling and adjusting at least one of an irradiating direction, an intensity, a pattern, or a spectral power, of the at least one ultraviolet radiation source, based on attribute information acquired by the at least one sensor.

18. A system, comprising:

an ultraviolet radiation containing case including a flowable product stored therein;

an inert enclosure located inside the ultraviolet radiation containing case, the inert enclosure including at least one ultraviolet radiation source mounted thereon that is configured to emit ultraviolet radiation onto at least one of the flowable product or an interior of the ultraviolet radiation containing case, and a control system configured to control operation of the at least one ultraviolet radiation source; and

an external controller operatively coupled to the inert enclosure, the external controller configured to allow an operator to remotely control disinfection of the flowable product and the interior of the ultraviolet radiation containing case with the inert enclosure, the external controller having a communication channel with the control system in the inert enclosure that permits the operator to remotely control operation of the at least one ultraviolet radiation source for disinfection of the at least one of the flowable product or the interior of the ultraviolet radiation containing case.

19. The system of claim 18, wherein the external controller includes a wireless controller.

20. The system of claim 18, wherein the inert enclosure further includes a sensor operatively coupled to the control system in the inert enclosure, wherein the sensor is configured to detect when the inert enclosure is no longer enclosed by the ultraviolet radiation containing case, and the control system is configured to turn off the at least one ultraviolet radiation source in response to the sensor detecting that the inert enclosure is no longer enclosed by the ultraviolet radiation containing case.
