Abstract: A multi-layer article includes a non-active state and an active state. The multi-layer article includes at least one layer that includes a volatile material therein. The multi-layer article is folded along an axis so that an upper portion of the multi-layer article is disposed on a lower portion of the multi-layer article.

Abstract: A multi-layer article includes a non-active state and an active state. The multi-layer article includes an outer layer with a first side and a second side, and at least one inner layer that is disposed adjacent to at least a portion of the outer layer and that includes a volatile material therein. The at least one inner layer is coupled to the outer layer in both the active state and the non-active state. The multi-layer article is folded along an axis so that an upper portion of the multi-layer article is disposed on a lower portion of the multi-layer article. The outer layer is a non-porous, non-permeable material that includes an aperture.

Abstract: A method of operating a dispenser for consistently emitting a volatile material is provided. The dispenser has a front face and a rear face and is provided for use in the emanation of the volatile material into an ambient environment. A substrate with the volatile material is dosed. The substrate is positioned between the front face and the rear face. The substrate 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.

Abstract: A substrate for emitting a volatile material, the substrate comprising a first woven layer, a second woven layer, and a third layer. The first woven layer has a first weave pattern. The second woven layer has a second weave pattern that is different than the first weave pattern. The third layer is disposed between the first woven layer and the second woven layer. Further, the substrate 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.

Abstract: A multi-layer article including a first non-active state and a second active state, the multi-layer article comprising an outer layer having a first side and a second side, an inner layer adjacent to at least a portion of the outer layer and including a volatile material, and an upper layer including a first side and a second side, the first side of the upper layer being adjacent to at least a portion of the inner layer. The multi-layer article is folded upon itself in the first non-active state so that at least a first portion of the second side of the upper layer is disposed on a top of a second portion of the second side of the upper layer, and the first portion and the second portion of the upper layer are heat sealed in the non-active state.

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.
