Abstract

A system for consistently emitting a volatile material, the system including a dispenser having at least one aperture, a substrate adapted to fit within the dispenser, and a volatile material. The substrate includes a first woven layer having a first pore size, a second woven layer having a second pore size, and a third, non-woven layer that extends between the first woven layer and the second woven layer. Further, the system has a steady state weight loss of the volatile material over a time greater than 30 days.

Claims (33)

1. A system for consistently emitting a volatile material, the system comprising:

a dispenser having at least one aperture; and

a layered substrate adapted to fit within the dispenser, the layered substrate including:

a first woven layer having a first pore size;

a second woven layer having a second pore size;

a third non-woven fiber layer extending between the first and second woven layers; and

a volatile material including an active agent that is applied to at least one of the first woven layer, the second woven layer, and the third non-woven fiber layer;

wherein the system is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

2. The system of claim 1 , wherein the active agent is selected from the group consisting of metafluthrin, transfluthrin, tefluthrin, and vaporthrin.

3. The system of claim 1 , wherein the first pore size of the first woven layer is between about 1 millimeter and about 10 millimeters.

4. The system of claim 1 , wherein the active agent is in an amount of between about 5% by weight and about 95% by weight of the volatile material.

5. The system of claim 1 , wherein an initial weight of the volatile material is between about 1 gram and about 5 grams.

6. The system of claim 1 , wherein the at least one aperture of the dispenser exposes a portion of the first woven layer.

7. The system of claim 6 , wherein the least one aperture of the dispenser exposes between about 50% and about 99% of a surface area of the first woven layer.

8. The system of claim 1 , wherein the system is configured to provide a steady state weight loss of the volatile material over a time of at least 60 days.

9. The system of claim 8 , wherein the system is configured to provide a steady state weight loss of the volatile material over a time of at least 70 days.

10. The system of claim 1 , wherein the first pore size is different than the second pore size.

11. The system of claim 1 , wherein the dispenser includes a front face and a rear face, and the front face includes the at least one aperture.

12. The system of claim 1 , wherein the first woven layer, the second woven layer, and the third non-woven fiber layer are constructed from the same material.

13. The system of claim 1 , wherein the first woven layer and the second woven layer are constructed from a first material, and the third non-woven fiber layer is constructed from a second material that is different than the first material.

14. A system for consistently emitting a volatile material, the system comprising:

a frame having at least one aperture;

a layered substrate positioned within the frame, the layered substrate including:

a first woven layer having a plurality of pores;

a second woven layer having a plurality of pores; and

a third non-woven fiber layer extending between the first and second woven layers; and

a volatile material including an active agent that is applied to at least one of the first woven layer, the second woven layer, or the third non-woven fiber layer,

wherein the system is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

15. The system of claim 14 , wherein the steady state weight loss of the volatile material is between about 4 mg/day and about 6 mg/day.

16. The system of claim 14 , wherein the active agent of the volatile material is selected from the group consisting of metafluthrin, transfluthrin, tefluthrin, and vaporthrin.

17. The system of claim 16 , wherein an initial weight of the volatile material is between about 2 grams and about 3 grams.

18. The system of claim 17 , wherein the system is configured to provide a steady state weight loss of the volatile material over a time of at least 70 days.

19. The system of claim 18 , wherein the frame includes a first aperture that exposes a portion of the first woven layer and a second aperture that exposes a portion of the second woven layer.
