This disclosure relates to the field of masks, and, in particular, sleep masks. This disclosure also relates to a method of producing a mask.
This application claims priority to Australian provisional patent application number 2021902041, filed Jul. 5, 2021, the disclosure of which is incorporated by reference in its entirety.
Research has shown that sleep masks can have a positive effect on sleep, promoting melatonin and cortisol levels, and increasing REM (rapid eye movement) sleep. Sleep masks are known to aid in blocking intrusive or undesired light and can be used by people who have (for example): i) trouble falling asleep; ii) insomnia or other sleep disorders; iii) a need to sleep during the day due to (for instance) shift work; or iv) a wish to sleep while travelling, such as on airplanes.
Key features of a sleep mask are the ability to block as much light as possible and the ability to remain in place while the wearer is asleep. However, the technical field of sleep masks is still largely undeveloped and compromises between features such as comfort, shape, the weight of the mask and the material used are unrefined. Dermatological concerns are also commonly overlooked in the design of sleep masks and finer materials are ignored due to complexities in production.
Accommodating for different facial features also remains an undeveloped area for sleep masks. Whilst some sleep masks have attempted to accommodate, for example, eye lash extensions, these look and feel akin to wearing swimming goggles and lack refinement. Furthermore, as these masks fail to appreciate the contours of a face, the eye lash extensions may still contact the sleep mask leading to damage of the eye lash extensions.
Bearing this in mind, the present inventor(s) have developed a new mask, which is particularly suitable as a sleep mask.
Any reference to or discussion of any document, act or item of knowledge in this specification is included solely for the purpose of providing a context for the present invention. It is not suggested or represented that any of these matters or any combination thereof formed at the priority date part of the common general knowledge, or was known to be relevant to an attempt to solve any problem with which this specification is concerned.

Further features and advantages of the present disclosure will become apparent from the following detailed description.
By way of example only, embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying figures, wherein:
The body 100 has a largely straight edge 110 along the top of the body 100 and smooth curves at opposing sides 120 of the body 100. The bottom of the body 100 has two symmetrical curves 130 that substantially form a w-shape. The two curves 130 have a nose portion 150 spaced between them. The nose portion 150 is designed to sit across the bridge of the wearer's nose. The body 100 has a height (H) of approximately 96 mm and a width (W) of approximately 210 mm (as depicted in
The face portion 200 is shown further in
The face portion 200 conforms to the recesses 300 (or vice versa). The contoured recesses 300 are associated with the eyes of a wearer when the sleep mask 10 is worn. That is, the contoured recesses 300 align with a wearer's eyes during use. As detailed further below, the shape of the contoured recesses 300 ensure that there is no or limited contact of the eyelashes or eyelash extensions to the mask 10 itself and in turn to the wearer's pillow or bedding. The contoured recesses 300 include an upper ridge 310, an upper taper 315, a lower ridge 320, a lower taper 325, a side ridge 330 and a valley portion 340. The contoured recesses 300 are moulded into shape. In other words, the contoured recesses 300 are formed into specific, gradual shapes that suitable fit onto a wearer's face.
The upper ridge 310 is configured engage against a forehead of the wearer. The upper ridge 310 is substantially located above the retaining part 700. The upper ridge 310 extends adjacent to an upper portion of the valley portion 340. The lower ridge 320 extends adjacent to a lower portion of the valley portion 340. The lower ridge 320 is configured to engage against a cheek area of the wearer. The lower ridge 320 extends further away from the outer portion 500 of the body 100, in a direction towards the eyes of the wearer, compared to the upper ridge 310. This assists with the body 100 conforming to a variety of faces and, for example, blocking out sunlight whilst eyelash extensions are not compromised. The approximate width (F) of the ridges is approximately 28 mm to 29 mm and this may vary ±7.5 mm.
An upper taper portion 315 is formed between the upper ridge 310 and the valley portion 340. A lower taper portion 325 is also formed between the lower ridge 320 and the valley portion 340. The distance (T) between the upper end of the taper portion 315 and the upper end of taper portion 325 is approximately 49 mm. This distance (T) may vary between 38 and 58 mm. The lower taper 325 is formed with a shallower angle than the upper taper 315. This again assists with suitably conforming the body 100 to multiple wearers. In addition, as detailed further below and evident in
A side ridge 330 is located between the upper ridge 310 and lower ridge 320. As will be appreciated by a person skilled in the art, the ridges 310, 320 and 330 form one uniform ridge but the structure of each part has been detailed. The side ridges 330 are located adjacent the retaining part 700. The side ridges 330 assists in blocking out light to the right and left of a wearer.
As evident in
The padding part 350 is polyester in this embodiment. However, in further embodiments, the padding part 350 may be a memory foam. The memory foam may include polyurethane. The padding part 350 has an average density of approximately 32.6 kg/m3 and this may vary between approximately 28 kg/m3 to 38 kg/m3. To this end, as shown in
As shown in
The outer portion 500 (further shown in
As indicated above, the sleep mask 10 is held in place over the wearer's eyes with a retaining part 700. The retaining part 700 extends from a first side of the body 100 to a second opposing side of the body 100. The retaining part 700 is configured to extend around the back of the head of the wearer. The retaining part 700 is substantially located to one side of the axis 12. The retaining part 700 is made of a flexible material, preferably elastic. The flexible material is covered by silk (and in further embodiments may be covered by satin). The retaining part 700 has a crumpled and/or pleated look.
During use, a wearer stretches the retaining part 700 to place it around their head. The body 100 is positioned on the wearer's face such that the nose portion 150 sits on the wearer's nose. In this position, at least the ridges 310, 320, 330 distance the valley portion 340 in a position away from the wearer's face such that, if eye lash extensions are used, they do not engage with the recess portions 300.
With the above in mind, the sleep mask 10 or certain embodiments may be capable of achieving certain advantages. These advantages may include some or all of the following: reducing contact of all or portions of a wearer's eyelash extensions and/or long eyelashes with the sleep mask 10, the wearer's pillowcase and/or other bedding, thereby protecting the shape and bond of any eyelash extensions or long eyelashes; reducing contact between the wearer's eyes and the mask 10, thereby increasing user comfort for those users who do not like to sleep with a traditional sleep mask which compresses/touches their eyes; simultaneously providing function of a traditional sleep mask, including by blocking light to the wearer's external environment; and improving wearer comfort via composition of each component of the product.
