As illustrated in
The air freshener 10 comprises a container 14 that contains a fragrant material, such as a fragrant gel material, from which a fragrance permeates over time. The container 14 contains at least two different fragrant materials, such as first and second fragrant materials 18a and 18b with different fragrances, such as first and second fragrances. The fragrances can be complimentary. The two fragrances can combine in a synergistic manner with the combined scent being more pleasing or different than either scent individually. The fragrant materials can be separate and discrete with respect to one another in the container. The first fragrant material can be an outer fragrant material, while the second fragrant material can be an inner fragrant material. The fragrant gel material can be a water based gel. In addition, the fragrant material can be transparent or at least translucent. The container 14 can have a cylindrical shape or a cylindrical-shaped perimeter to accommodate rotation as discussed below. In addition, the container 14 can have an outer perimeter wall 20. Furthermore, the container 14 can have a closed bottom and an open upper end or upper opening.
The container 14 can be a divided into separate and discrete containers or reservoirs, including an inner cylindrical reservoir 22 or container, and an outer annular reservoir 26 or container being separate and discrete from, and circumscribing, the inner cylindrical reservoir. The container 14 can be formed by an outer annular container and an inner cylindrical container. Each of the at least two different fragrant materials is disposed in a different one of the reservoirs. The first fragrant material 18a can be disposed in the outer annular reservoir 26 or container, and the second fragrant material 18b can be disposed in the inner cylindrical container 22. Thus, the outer annular container can have the annular reservoir, and can contain the first fragrant material. Similarly, the inner cylindrical container can be circumscribed by the outer annular container, and can have the cylindrical reservoir, and can contain the second fragrant material.
As described above, the reservoirs or containers can be separate and discrete, or can have separate and discrete volumes, as shown in
The inner cylindrical container or reservoir 22 and the outer annular container or reservoir 26 can be separately formed. Each of the inner cylindrical container or reservoir 22 and the outer annular container or reservoir 26 can be formed as a single, integral, monolithic piece that is formed together, such as of plastic in an injection molding process. Thus, the inner cylindrical container or reservoir 22 can be formed as a cup with a bottom wall and the opposing wall or innermost wall 34. Similarly, the outer annular container or reservoir 26 can be an annular cup with a bottom wall and the outer wall 20 and inner wall or outermost wall 30. The two containers or reservoirs 22 and 26 can be joined together to form the container 14. For example, an interlocking coupling 42 can be formed between the containers or reservoirs 22 and 26 at a bottom inner rim of the outer annular container or reservoir 26, and at a bottom outer rim of the inner cylindrical container 22. For example, each bottom rim can include a plurality of teeth that intermesh to connect the containers and resist rotation of the containers with respect to one another. The rims or teeth can be adhered together. The bottom walls of the containers can be co-planar or flush with a support surface upon which the container is disposed.
The containers or cups can be formed of, or can include, a material that resists reacting with the fragrant gel material, such as polypropylene. In addition, the container or cups, or walls thereof can be transparent, or at least translucent, so that the fragrant material is visible therethrough. In addition, the fragrant material, or at least the first fragrant material, can be transparent, or at least translucent, so that the second fragrant material is visible therethrough.
The air freshener 10 also comprises a cap 50 or lid carried by the container 14 and disposable on the container over the open upper end to cover the containers or reservoirs 22 and 26. The cap 50 can be part of the container 14. A sleeve 54 extends from the cap 50 into the container 14, and into the annular gap 38 between the containers or reservoirs 22 and 26, and between the pair of cylindrical walls 30 and 34. The sleeve 54 is cylindrical to match the annular gap and the pair of cylindrical walls 30 and 34. The sleeve 54 can have at least one lateral or radial aperture or opening 58. In one aspect, the at least one aperture 58 can include a plurality of apertures or holes circumscribing the sleeve, and disposed adjacent the top thereof. The cap 50 and the sleeve 54 are movable axially with respect to the container 14 (and thus containers or reservoirs 22 and 26) between a raised position (
In one aspect, the cap and the sleeve can extend linearly vertically or axially towards and away from the container, and can be held by a friction resistance or interference fit between the sleeve and the pair of walls. In another aspect, mating screw threads can be formed between the sleeve and the pair of walls such that rotation of the cap moves the cap axially with respect to the container. For example, an inner screw thread 62 can be formed on the inner wall or outermost wall 30 of the outer annular container or reservoir 26. Similarly, an exterior screw thread 64 can be formed on the sleeve 54, and can engaging the interior screw thread 62. The screw threads do not need to be continuous, but can be segmented to form portions of screw threads, such as shown by screw threads 62 in
The cap 50 and the sleeve 54 can comprise an inverted cup 70 and an outer annular cap 74 coupled together. The inverted cup 70 can have a top wall covering the inner cylindrical container or reservoir 22, and abutting to an upper rim thereof in the closed position. In addition, the inverted cup 70 can have a side wall forming the cylindrical sleeve. The inverted cup 70 can be formed of, or can include, a material that is reactable with the fragrant gel material, such as polystyrene, but is separated from the fragrant gel material by the pair of walls 30 and 34. In another aspect, the inverted cup can be formed of, or can include, a material that resists reacting with the fragrant gel material, such as polypropylene. At least the top wall of the inverted cup, and thus at least a portion of the cap 50 over the inner container or reservoir 22, is transparent, or at least translucent, so that the second fragrant material 18b is visible therethrough. The inverted cup can be translucent or transparent, including the sleeve. The outer annular cap 74 can coupled to the inverted cup 70, and can cover the outer annular container or reservoir 26, and can abut to an upper rim thereof in the closed position. The outer annular cap can have an annular groove or channel formed around a perimeter thereof to receive the upper rim of the outer wall in the closed position. In addition, the outer annular cap can have a center aperture to receive the top wall of the inverted cup. The inverted cup can have a projection extending into the center aperture of the outer annular cap. The outer annular cap and the inverted cup can be adhered together. The outer annular cap can be opaque.
As described above, the outer annular container 26, the inner cylindrical container 22, the cylindrical sleeve 54, and the first fragrant material 18a can be at least translucent so that the second fragrant material 18b is visible laterally therethrough. The outer wall 20 of the outer annular container 26 can be at least translucent, and the first fragrant material 18a can be visible laterally therethrough. At least a portion of the cap 50, such as the top wall of the inverted cup 70, over the inner cylindrical container 22 can be at least translucent so that the second fragrant material 18b is visible axially therethrough.
