DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0011] In the following description, like numbers refer to like elements.

[0012] FIGS. 1 to 4 depicts an embodiment of a wearable device 100 that connects to a person's clothing and diffuses aroma compounds for inhalation by the person wearing the device. The embodiment is intended to be representative of devices that incorporate one or more of the features described below. The device 100 is comprised of an enclosure 102 that may be connected to clothing (not shown) at a location desired by the person wearing the device. It may further comprise a substrate 104 containing aroma compounds or other chemical compounds that will volatilize or evaporate at or around normal room temperatures, without the application of heat, and diffuse into the atmosphere outside the enclosure through a plurality of openings106 defined in a front side 108 of the enclosure. The enclosure 102 retains the substrate 104. The substrate cannot fall out of or be removed from the enclosure when it is in a closed position, as shown in FIGS. 2-4, and must be opened as shown in FIG. 1.

[0013] In alternative embodiments, the front side may one or more openings. Each opening has a shape and size that prevents the substrate from falling through it.

[0014] The number and size of openings may be chosen or, optionally, made adjustable to increase or decrease the total area of the openings to increase or decrease the rate diffusion of vapor. In the illustrated embodiment, the openings relatively long and narrow, which provide a relatively large amount of open area while still retaining the substrate and restricting visual sight lines into the disclosure. However, in alternative embodiments, the openings may have a different shape, or multiple different shapes, and may have multiple different sizes. Furthermore, the openings may be partially or completely covered using louvered or mesh-like structure that vapors to escape but also retain the substrate within the disclosure and make it more difficult to see inside the disclosure. Furthermore, the shape, size, and arrangement of openings may be chosen to create decorative patterns that make the device more aesthetically pleasing. Although the illustrated embodiment does not have any, the enclosure may optionally have one or more openings located elsewhere in the enclosure, from which vapor may be diffused.

[0015] The enclosure in this embodiment has a relatively narrow thickness 108 (measured front to back) as compared to its length 110 and width 112. This gives it a relatively low profile when worn with its back surface 114 is placed next to the person's clothing.

[0016] Disposed on the back surface 114 is a fastener 116 that is capable of connecting the enclosure to clothing worn by a person and/or that is capable of connecting the enclosure to a fashion accessory worn by the person, such as a necklace. In this representative example the fastener comprises a clip capable of pinching a small amount of fabric to hold the enclosure on clothing, such as a shirt, blouse, dress or coat, allowing it to be placed in the vicinity of the wearer's nose. Optionally, the clip is capable of clasping a necklace or similar fashion accessory. Alternative, non-limiting examples of fasteners that may be suitable include hooks, buttons, pins, clasps, and similar fasteners that are capable of attaching the enclosure to clothing and/or fashion accessories.

[0017] The substrate functions to contain compounds to be evaporated to create the desired vapor for inhaling. The substrate is relatively thin as compared to its length and width, which allows it to have a large area for evaporation that faces openings 106 while permitting the enclosure 102 to be relatively. The substrate may be provided with the enclosure or provided separately. It may also be provided without the compounds to be evaporated, permitting a user to add the compounds to the substrate. Non-limiting example of the substrate 104 includes a pad that is comprised of a thin, relative to its length and width, piece of absorbent material. The pad may, optionally, be provided soaked or saturated with a liquid containing the compounds to be evaporated. Alternatively, the substrate can made of another type of solid material capable of holding the compounds to be evaporated. Non-limiting examples of liquids held by the pad or substrate include essential oils.

[0018] In one embodiment, the enclosure is provided with one or more substrates, such as pads. In another embodiment, the enclosure is provided with one or more replaceable substrates containing the compounds to be evaporated in a sealed package, non-limiting examples of which include pads containing with a liquid that includes compounds to be evaporated and pads soaked, impregnated, or saturated with essential oils.

[0019] A tray 118 with a receptacle 120 for holding the substrate 104 is received within the enclosure 102. The tray swings outwardly from the enclosure from a closed position shown in FIGS. 2-4 to an open position, one of which is shown in FIG. 1, that makes receptacle 120 accessible to insert a substrate into or remove (and optionally replace or change) a substrate from the enclosure 102, The tray comprises a rim 122 rising from a relatively flat bottom surface of the tray (not shown) and extending around the perimeter of the tray, thereby defining the receptacle 120 that holds the substrate 104. The receptacle holds the substrate when the enclosure is open and closed, thus making it relatively simple, easy and quick to place, change, or recharge a substrate 104. The receptacle 120 and substrate 104 may, optionally, have complementary shapes, like the one shown in FIG. 1, to reduce movement of the substrate within the enclosure. It is preferable, though not required, that the receptable have dimensions allows some room between it and the rim 122 for manually grasping the substrate to remove it.

[0020] The illustrated embodiment of enclosure 102 is comprised of a front wall 124, a a back wall 126 and a side wall 128 that joins front wall 124 and 126. The top, bottom and side walls at least partially define interior volume or chamber 130 in which tray 118 is received. When received, the tray cooperates with a bottom surface of the front wall 124 to trap the substrate 104. The top and back walls are flat and are spaced apart at the same distance. They could be said to be substantially planar and parallel to each other. They are also have substantially the same, rectangular shape and dimensions. The result is an enclosure and a chamber having box-like shapes. These characteristics offer certain advantages in terms of construction, assembly and closeness and ease of fit of the tray within chamber 130. However, in alternative embodiments, the top and back walls could be concave or convex and can differ in size and/or shape; they need not be parallel or spaced apart along their respective perimeters at a consistent distance. For example, each of the top and back walls could have triangular, polygonal, or other rectilinear shapes; circular, elliptical or other curved or arcuate shapes; a combination of straight and curved sides; or free-form.

[0021] The side wall 128 extends only partially around the perimeters of front wall 124 and back walls 126 to allow the tray 118 to be able to rotate or pivot about axis 132 between the closed position shown in FIGS. 2-4 and the open position shown in FIG. 1. The tray 118 is comprised of an outer side wall 134 that, when the tray is in a closed position, cooperates with at least the front wall 124 to prevent the substrate104 from falling out of the device 100 when the tray is rotated to the closed position. Although not required, a top edge 136 of outer side wall 134 of the tray fits closely with a bottom surface (not visible) of the front wall 124. It also aligns with the outer perimeter edge 137 of the front wall 124, and a bottom, outer perimeter edge 138 of the tray aligns with an outer perimeter edge 140 of the back wall 126.

[0022] Rather translating linearly, the tray rotates or pivots about an axis 132 to allow the tray to be swung out of the enclosure 102 while remaining joined to it, though it still may be removed. The tray includes a pocket 142 that receives a post or pin 144, around which the tray rotates. The pocket is open, which allows the tray to be removably retained to the pin using, for example, spacer or bearing 146 or other means.

[0023] Room temperature is, in one embodiment, between 60 and 100 degrees and, in another embodiment, between 65 and 80 degrees.

[0024] The foregoing description is of exemplary and preferred embodiments. The invention, as defined by the appended claims, is not limited to the described embodiments. Alterations and modifications to the disclosed embodiments may be made without departing from the invention. The meaning of the terms used in this specification are, unless expressly stated otherwise, intended to have ordinary and customary meaning and are not intended to be limited to the details of the illustrated or described structures or embodiments.
