DETAILED DESCRIPTION
[0041] Referring to FIGS. 1-2 and 9-11, the present disclosure describes a device 10 for removably fastening to a mask 12 to more safely permit nourishment, and a protective headwear 14 that includes the mask 12 and the device 10.
[0042] Referring to FIGS. 3-8 and 12-14, the device 10 includes a ring-shaped body 16 and at least one membrane 18, 20. The body 16, which may be in the form of a grommet, has an outer surface and defines an inner opening 22 (see FIGS. 8, 12, 13). The outer surface of the body 16 is mountable about a hole 24 (see FIG. 4, 9, 12, 13) in the mask 12 in a mouth region of the wearer, such that the inner opening 22 of the body 16 at least partially overlaps with the hole 24. The membrane 18, 20 is connected to the body 16 to substantially close the inner opening 22. The membrane 18, 20 includes at least one slit 26, 28 to permit passage of a utensil 30 (e.g., a straw) through the membrane 18, 20.
[0043] Referring to FIGS. 3-8 and 12-14, the body 16 of the device 10 includes first and second body portions 32, 34 that engage respective surfaces on opposite sides of the mask 12. In the illustrated embodiments, the first body portion 32 engages an outer side surface of the mask 12, while the second body portion 34 engages an inner side surface of the mask 12.
[0044] In some embodiments (see FIGS. 1-8), the first and second body portions 32, 34 of the device 10 are discrete components that are removably connectable to one another (e.g., via a snap-fit or threaded connection). In some such embodiments, at least one of the first and second body portions 32, 34 includes a sharp edge 36 for piercing the mask 12 to form the hole 24. Referring to FIGS. 3-8, in the illustrated embodiment, the first body portion 32 includes an annular collar 38 that at least partially defines the inner opening 22 (see FIG. 8), and an annular flange 40 that extends radially from the collar 38. The second body portion 34 similarly includes an annular collar 42 and an annular flange 44 that extends radially from the collar 42. The sharp edge 36 (see FIGS. 3-4) is provided on the end of the collar 38 of the first body portion 32 opposite the flange 40. The flange 44 of the second body portion 34 defines an opening 46 (see FIG. 3) configured to receive the sharp edge 36 of the first body portion 32 when the first and second body portions 32, 34 are fit together to create the hole 24 (see FIG. 4) by cutting the mask 12, as shown sequentially in FIGS. 3-5. When connected to one another, the first and second body portions 32, 34 are concentrically aligned relative to an axis 48 of the device 10.
[0045] Referring to FIG. 7, in some embodiments in which the first and second body portions 32, 34 of the device 10 are discrete components that are removably connectable to one another, at least one of the first and second body portions 32, 34 includes radial ribs 50, 52 to facilitate rotation of the one of the body portions 32, 34 relative to one another for installation and removal of the device 10 relative to the mask 12. Referring to FIGS. 7 and 8, in the illustrated embodiment, the flange 40 of the first body portion 32 includes four (4) radial ribs 50 disposed thereon, and the flange 44 of the second body portion 34 includes four (4) radial ribs 52 disposed thereon. The first and second body portions 32, 34 fit together via threaded connection. The outer surface of the collar 38 of the first body portion 32 defines male threads that threadably engage female threads defined on the inner surfaces of the flange 42 and collar 44 of the second body portion 34. The ribs 50, 52 facilitate rotation of the first and second body portions 32, 34 relative to one another during threaded connection and disconnection of the first and second body portions 32, 34.
[0046] In some embodiments (see FIGS. 9-14), the first and second body portions 32, 34 of the device 10 are integrally connected to one another. In some such embodiments, the device 10 is configured to be installed into a pre-defined hole 24 in the mask 12. Referring to FIGS. 12-14, in the illustrated embodiment, the first and second body portions 32, 34 of the device 10 are integrally connected to one another and define an annular groove 54 (see FIG. 12) therebetween. The device 10 is configured to be installed into a pre-defined hole 24 in the mask 12 (see FIG. 9). The mask 12 is made of a flexible material. The user stretches the material to expand the size of the pre-defined hole 24 and thereby permit installation of the device 10. Once installed, the groove 54 of the body 16 engages the edge 55 (see FIGS. 12-13) of the mask 12 that defines the hole 24.
[0047] In some embodiments (see FIGS. 1-8), the device 10 includes more than one membrane 18, 20, and/or each membrane 18, 20 includes more than one slit 26, 28. Referring to FIGS. 7 and 8, in the illustrated embodiment the device 10 includes a first membrane 18 disposed relative to first body portion 32 of the device 10, and a second membrane 20 disposed relative to the second body portion 34 of the device 10. The first membrane 18 includes four (4) slits 26 that intersect at a center of the first membrane 18, and the second membrane 20 includes four (4) slits 28 that intersect at a center of the second membrane 20.
[0048] In other embodiments (see FIGS. 9-14), the device 10 includes a single membrane 18 disposed relative to one of the first and second body portions 32, 34. Referring to FIGS. 12-14, in the illustrated embodiment the device 10 includes a single membrane 18 disposed relative to the first body portion 32 of the device.
[0049] The body 16 and the one or more membranes 18, 20 of the device 10 can be made of various types of materials. In the illustrated embodiments, the body 16 is made of a rigid plastic material, and the membranes 18, 20 are made of a flexible rubber that is overmolded onto the body 16.
[0050] The mask 12 is a respirator mask, an n95 mask, a surgical mask, a buff, a neck gaiter, or another component that covers at least the mouth of a user. Referring to FIGS. 1-2, in the illustrated embodiment the mask 12 is a respirator mask with a plurality of straps 56 for mounting onto the wearer's head. Referring to FIGS. 9-11, in the illustrated embodiment the mask 12 is a buff.
[0051] The mask 12 can be made of various types of known materials, including woven materials, non-woven materials, plastics, etc.
[0052] Referring to FIGS. 2, 6, 11, 14, after the device 10 is installed relative to the mask 12, the wearer can insert a utensil 30 (e.g., a straw) to more safely permit nourishment without the need for removal of the mask 12. The wearer can remove the device 10 from the mask 12 before disposal of the mask 12. For example, in the embodiment of FIGS. 1-8, the device 10 is removed from the mask 12 by rotating the first and second body portions 32, 34 relative to one another about the axis 48 to undo the threaded connection therebetween. Once the device 10 has been removed from the mask 12, the device 10 can be reused with a new mask 12. The reusable nature of the device 10 avoids the high cost of providing a plurality of masks with the same functionality built into each mask.
[0053] While several embodiments have been disclosed, it will be apparent to those having ordinary skill in the art that aspects of the present invention include many more embodiments. Accordingly, aspects of the present invention are not to be restricted except in light of the attached claims and their equivalents. It will also be apparent to those of ordinary skill in the art that variations and modifications can be made without departing from the true scope of the present disclosure. For example, in some instances, one or more features disclosed in connection with one embodiment can be used alone or in combination with one or more features of one or more other embodiments.
