Abstract
A face mask comprises a container coupled to a first surface of a face mask, a fragrance material disposed in the container, and an exhalation valve coupled to a second surface of the a face mask. The fragrance material comprises a fluid configured to evaporate from the fragrance material, and the container is configured to releasably engage the exhalation valve to form a closed chamber. The closed chamber is configured to enclose the fragrance material when the container is releasably engaged with the exhalation valve.
Claims19
A mask comprising:
- a container coupled to a first surface of a mask;
- a fragrance material disposed in the container, wherein the fragrance material comprises a fluid configured to evaporate from the fragrance material and into an interior of the mask;
- and
- an exhalation valve coupled to a second surface of the mask, wherein the container is configured to releasably engage the exhalation valve to form a closed chamber in an instance in which the mask is folded along a center fold line, the closed chamber is configured to enclose the fragrance material when the container is releasably engaged with the exhalation valve, wherein the container is further configured to disengage the exhalation valve-to open the chamber to allow the fragrance material to evaporate in an instance in which the mask is unfolded, and wherein the exhalation valve is separate from the container,
- wherein the exhalation valve comprises a valve base and a valve plate coupled to the valve base, wherein the valve plate forms a seal with the valve base to seal the fragrance material, wherein the seal is adapted to prohibit evaporation of the fragrance material until the mask is unfolded.

A method of determining an end of service life of a mask, the method comprising:
- exposing a fragrance material that is retained in a container coupled to an interior surface of a mask to an interior of the mask by unfolding the masks to disengage the container from an exhalation valve, wherein the fragrance material initially comprises a predetermined amount of fragrance composition;
- engaging the container with the exhalation valve in an instance in which the mask is folded along a center fold line, wherein the exhalation valve is coupled to a surface of the mask, and wherein the fragrance material is retained between the container and the exhalation valve while the container is engaged with the exhalation valve, wherein the exhalation valve is separate from the container;
- vaporizing the predetermined amount of fragrance composition while the fragrance material is exposed to the interior of the mask, wherein the exhalation valve comprises a valve base and a valve plate coupled to the valve base, wherein the valve plate forms a seal with the valve base to seal the fragrance material,
- prohibiting, via the seal, evaporation of the fragrance material until the mask is used;
- evaporating a predetermined quantity of the predetermined amount of fragrance composition;
- and
- determining an end of service life of the mask based on evaporating the predetermined quantity of the predetermined amount of fragrance composition.
4 more elements
A mask comprising:
- a container coupled to a first surface of a mask;
- a fragrance material disposed in the container, wherein the fragrance material comprises a fragrance composition configured to evaporate from the fragrance material and provide a scent within an interior of the mask;
- a visual indicator disposed on an outer surface of the mask, wherein the visual indicator corresponds to the scent provided by the fragrance composition;
- and
- an exhalation valve configured to engage the container in an instance in which the mask is folded along a center fold line and to disengage the container in an instance in which the mask is unfolded, the exhalation valve comprising a valve base and a valve plate coupled to the valve base, wherein the valve plate forms a seal with the valve base to seal the fragrance material, wherein the seal is adapted to prohibit evaporation of the fragrance material until the mask is used wherein the exhalation valve is separate from the container.
