Abstract

A dispensing device for release of a volatile material includes a base, a drive arm coupled to a pendulum based drive mechanism, and a refill coupled to the drive arm. The refill includes a support base, at least one flange, a substrate coupled with the at least one flange, and a use-up cue.

First claim

We claim:

1. A dispensing device for release of a volatile material, comprising:
a base;
a drive arm coupled to a pendulum based drive mechanism; and
a refill coupled to the drive arm,
wherein the refill includes:
a support base and at least one flange,
a substrate coupled with the at least one flange, and
a use-up cue.

2. The dispensing device of claim 1 further including one or more magnets disposed along a lower arm of the drive arm.

3. The dispensing device of claim 1 further including a left flange and a right flange that extend from the support base, and
wherein the refill further includes a volatile material disposed on the substrate.

4. The dispensing device of claim 3 further including a center flange that extends from the support base.

5. The dispensing device of claim 1 further including one or more shade attachments coupled with the base.

6. The dispensing device of claim 5 , wherein the one or more shade attachments each include a plurality of flow apertures.

7. The dispensing device of claim 5 , wherein the one or more shade attachments are non-removably inserted into the base.

8. A refill for dispensing a volatile material, comprising:
a support base;
one or more flanges extending from the support base;
one or more retention mechanisms disposed on the support base;
a substrate coupled with the one or more flanges; and
a use-up cue.

9. The refill of claim 8 , wherein the use-up cue includes a semi-permeable membrane and a removable impermeable membrane is provided over the semi-permeable membrane.

10. The refill of claim 9 further including a frangible portion adjacent the use-up cue.

11. The refill of claim 9 , wherein the use-up cue includes a reservoir holding an indicator material, which diffuses through the semi-permeable membrane when the removable impermeable membrane is removed therefrom.

12. The refill of claim 8 further including a volatile material disposed on the substrate, and wherein the substrate comprises a non-woven material.

13. The refill of claim 12 , wherein the volatile material is one of metofluthrin or transfluthrin, and wherein the substrate comprises nylon.

14. A refill for dispensing a volatile material, comprising:
a support base;
at least one retention mechanism provided on the support base;
a substrate coupled with the support base, wherein a volatile material is provided on the substrate; and
one or more flanges provided along the substrate.

15. The refill of claim 14 , wherein the at least one retention mechanism includes a first indentation, a second indentation, and a groove.

16. The refill of claim 15 , wherein the first indentation and the second indentation extend outward from a front face of the support base.

17. The refill of claim 16 , wherein the groove extends outward from a back face of the support base.

18. The refill of claim 16 , wherein the first and second indentations are U shaped.

19. The refill of claim 14 , wherein the one or more flanges extend from the support base.

20. The refill of claim 19 further including a left flange, a right flange, and a center flange.
