Abstract
A mask (100) includes one or more airflow deflection protrusions (111 a-111 d) for deflecting an airflow away from a wearer (190, 230) to avoid bacteria, viruses, or any other harmful substances in the airflow from depositing on the head (192) and/or hair of the wearer (190, 230). A full face mask (300) comprising a flexible sheet (310), and the flexible sheet (310) having a top portion (311) comprising two fold structures (320, 321) located adjacent lateral edges (312 a,312 b) of the flexible sheet (310), respectively, for bending the top portion (311) towards the forehead of a wearer (190, 230). When the top (311) of the full face mask (300) is bent towards the forehead of the wearer (190, 230) by the folded structure (320, 321), a substantial portion of the face, forehead and skull of the wearer (190, 230) may be protected.
Description
Technical Field
The present disclosure relates generally to a mask for protecting a wearer's face.
Background
In various service industries, service providers (e.g., healthcare workers, dentists, cashiers, receptionists, and taxi drivers) need to face various customers located nearby. The transmission and subsequent deposition of body fluids, splashes and saliva from the customer to the service provider can cause various health or wellbeing problems. In the catering industry, hot oil splatter, boiling water and steam can harm a worker's face. In the factory, flying chips generated during the machining process may injure operators. In hospitals, bacteria or viruses may be transmitted to medical practitioners when they breathe, cough or vomiting to the medical practitioners. In the healthcare field (e.g., the elderly's home), caregivers may be faced with spilled water while bathing the elderly.
Thus, donning the mask may help reduce the above-described accidents. There are a variety of mask designs on the market, but most are heavy to wear for a long period of time, disposable and not reusable, difficult to sterilize due to the presence of different soft materials (e.g. rubber), uncomfortable due to the hood contacting and rubbing the face and causing skin reactions, or difficult to breathe due to insufficient space between the hood and nose. Furthermore, most lightweight masks on the market do not protect the front of the head and there is a large gap between the forehead and the mask. As a result, aerosol droplets may fall into the gap and deposit on the wearer's nose, eyes, forehead and/or hair.
Accordingly, there is a need for an improved mask that eliminates or at least reduces the above-described disadvantages and problems.

Detailed Description
It will be apparent to those skilled in the art that modifications, including additions and/or substitutions, can be made without departing from the scope and spirit of the invention. Specific details may be omitted to avoid obscuring the invention. However, the disclosure is written to enable any person skilled in the art to practice the teachings herein without undue experimentation.
The present disclosure provides a mask that includes one or more airflow deflection protrusions for deflecting the airflow away from the wearer, thereby avoiding the deposition of bacteria, viruses, or any other harmful substances in the airflow on the wearer's head and/or hair.
Figures 1A-1D depict a mask according to certain embodiments. The mask 100 includes a sheet 110 for protecting the face 191 of the wearer 190, headgear 120 for securing the mask 110 to the head of the wearer 190, and a connection member 130 for connecting the headgear 120 to the sheet 110. The sheet 110 is flexible and transparent and includes four airflow deflection protrusions 111a-111d and three head contact protrusions 112a-112c. Each airflow deflection protrusion 111a-111D protrudes outward from sheet 110 and is located below top edge 113 of sheet 110 for deflecting airflow away from wearer 190 (as shown in fig. 1D) when airflow is directed toward sheet 110. Since the aerosol entering in the airflow is deflected by the airflow deflecting projections 111a-111d, this greatly reduces the chance of bacteria, viruses or any other harmful substances depositing on the hair and/or head 192 of the wearer 190.
Each of the three head contact protrusions 112a-112c protrudes inwardly from the sheet 110 and is positioned below the top edge 113 for contact with the head 192 of the wearer 190 (as shown in fig. 1D). The head contact protrusions 112a-112c leave space between the sheet 110 and the face 191 of the wearer 190 to allow air to circulate over the face 191 for comfort of the wearer 190.
In this embodiment, the airflow deflection protrusions 111a-111d and the three head contact protrusions 112a-112c are arranged in a row in a consecutive order that is parallel to the top edge 113 to minimize the space of the sheet 110 occupied by the airflow deflection protrusions 111a-111d and the head contact protrusions 112a-112c.
In this embodiment, as shown in fig. 1B, the headband 120 includes a head headband portion 121 with a barbed hair clasp 1211 and a tail headband portion 122 with a rounded hair clasp 1221, and the barbed hair Mao Kou 1211 and rounded hair clasp 1221 are used to connect the head headband portion 121 and the tail headband portion 122 together so that the headband 120 enables the mask 100 to be securely and comfortably supported on the head 192 in a desired length. In this embodiment, the tab 110 includes four slots 131 located adjacent to the lateral sides 114a,114b of the tab 110, respectively. As shown in fig. 1C, the headband 120 includes a narrower portion 123 and a wider portion 124 along the length of the headband 120. The connecting member 130 includes a slot 131 at the tab 110 and a transition 132 between the narrower portion 123 and the wider portion 124 of the headband 120.
As shown in fig. 1C, the headband 120 is connected to the patch 110 by a connecting member 130. The narrower portion 123 has a width less than the width of the slot 131 for allowing the narrower portion 123 to pass through the slot 131, while the wider portion 124 has a width greater than the width of the slot 131 such that the wider portion 124 is stopped by the slot 131 at the transition 132. Narrower portion 123 may pass through slot 131 from the front surface to the rear surface of sheet 110 and vice versa.
In certain embodiments, the sheet is made of a chemical resistant material such that the sheet can be re-sterilized or cleaned by a sterilant or cleaner, thereby rendering the mask reusable. In certain embodiments, the sheet comprises a plastic that is inert to avoid any allergic problems to the wearer. The plastic may be polyethylene terephthalate (PET), polyethylene (PE), polyvinylchloride (PVC) or Polycarbonate (PC). The plastic may be a lightweight plastic so that the mask may be worn for extended periods of time.
In some embodiments, the sheet is flat and flexible, allowing the mask to be conveniently carried by storing it in a container (e.g., a bag, purse or backpack), so that it can be easily removed and assembled into a functional mask when needed for use.
In certain embodiments, the sheet and the airflow deflection protrusion are integrally molded and formed as one piece (e.g., by vacuum forming or thermoforming).
In certain embodiments, the airflow deflection protrusion is hollow.
In certain embodiments, each airflow deflection protrusion is rectangular, cubic, cylindrical, or semi-conical. In certain embodiments, the height of the airflow deflection protrusion (distance from the tab to the top of the protrusion) is between 3mm and 15mm, the length (along the horizontal axis of the tab) is between 5mm and 30mm, and the width (along the vertical axis of the tab) is between 1mm and 5 mm.
In some embodiments, the sheet, the air flow deflection protrusion, and the head contact protrusion are integrally molded and formed as one piece by vacuum forming or thermoforming.
In certain embodiments, the head contact protrusion is hollow.
In certain embodiments, the head contact protrusion is rectangular, cubic, cylindrical, or semi-conical. In certain embodiments, the head contact protrusion is semi-conical and has a height of between 3mm and 35mm, a bottom diameter of between 10mm and 50mm, and a top diameter of between 5mm and 25 mm.
The present disclosure also provides a full face mask that covers the entire face and a substantial portion of the anterior skull of the wearer. The full face mask may be bent at the top to protect the forehead and a large portion of the anterior skull. This reduces the chance of bacteria, viruses or any other harmful substances depositing on the forehead, the front of the head and the hair of the wearer.
In some embodiments, the full facemask includes a transparent plastic flexible sheet including a fold structure having a securing structure including a plurality of protruding balls and submerged balls on the upper left and upper right sides of the flexible sheet for securing the fold structure. The full face mask also includes headgear for securely and comfortably mounting the full face mask on the head in a desired length by various locking mechanisms so as not to apply constant stress to the head as does elastic headgear. This provides additional comfort to the wearer. After use, the wearer only needs to take out the full face mask and clean with a cleaning agent or bactericide. Without the need to disassemble the flexible sheet and headband.
In certain embodiments, the full face mask comprises: a flexible sheet for protecting a wearer's face, the flexible sheet having a top portion comprising two fold structures, each located adjacent a lateral edge of the flexible sheet, for bending the top portion towards the wearer's forehead, each fold structure comprising a first region located between the lateral edge and the second region, a cut line separating the first region from the second region, and a securing structure for securing the overlapping first and second regions together.

Fig. 3A depicts a full face mask according to some embodiments. The full face mask 300 includes a flexible sheet 310 having a top portion 311. The top 311 comprises a first fold 320 and a second fold 321 for bending the top 311 towards the forehead of the wearer. The first fold 320 and the second fold 321 are located face-to-face near (to the left and right of) the lateral edges 312a,312b of the flexible sheet 310, respectively.
The first folding structure 320 includes an outer region 320a, a middle region 330a, a cut line 321a, and a first fixing structure. The outer region 320a and the middle region 330a are part of the top 311. The outer region 320a is located between the lateral edge 312a and the middle region 330a, and the cut line 321a is located between the outer region 320a and the middle region 330a and separates the outer region 320a and the middle region 330 a. The flexible sheet 310 may be bent in the direction of the cutting line 321 a. The outer region 320a and the middle region 330a may be bent such that the outer region 320a and the middle region 330a overlap each other.
In this embodiment, a first securing structure is used to secure the overlapping outer and middle regions 320a, 330a together and includes a submerged ball 325 within the outer region 320a and a protruding ball 326 within the middle region 330a, as shown in fig. 3A. Protruding balls 326 and sinking balls 325 protrude from the rear side of flexible sheet 310. After the outer region 320a and the middle region 330a overlap each other, the protruding balls 326 may be attached to the sinking balls 325, respectively.
The second folding structure 321 includes an outer region 320b, a middle region 330b, a cut line 321b, and a second fixing structure. The outer region 320b and the middle region 330b are part of the top 311. The outer region 320b is located between the lateral edge 312b and the middle region 330b, and the cut line 321b is located between the outer region 320b and the middle region 330b and separates the outer region 320b from the middle region 330 b. The flexible sheet 310 may be bent in the direction of the cutting line 321 b. The outer region 320b and the middle region 330b may be bent such that the outer region 320b and the middle region 330b overlap each other.
In this embodiment, the second securing structure is used to secure the overlapping outer and middle regions 320b, 330b together and includes a submerged ball 335 within the outer region 320b and a protruding ball 336 within the middle region 330b, as shown in fig. 3A. After the outer region 320b and the middle region 330b overlap each other, the protruding balls 336 may be attached to the sinking balls 335, respectively.
As shown in fig. 3B, the flexible sheet 310 is bent in the direction of the cutting line 321B. The outer region 320b and the middle region 330b may be bent such that the outer region 320b and the middle region 330b overlap each other. After the outer region 320b and the middle region 330b overlap each other, the protruding balls 336 are attached to the sinking balls 335, respectively.
In this embodiment, the full face mask 300 further includes a plurality of rectangular head contact protrusions 350 located below the top portion 311, as shown in FIG. 3A.
Fig. 4 depicts a full face mask 410 having flexible sheets 411, headgear 412. The headband 412 includes a spine Mao Kou a at the head of the headband 412 and a circle Mao Kou b at the tail of the headband 412. The head and tail are connected together by a spike Mao Kou a and a round button 412b. The flexible sheet 411 includes a rectangular head contact protrusion 450.
In certain embodiments, the material used to make the full facepiece may be any kind of transparent plastic material, such as PET, PE, PP, PVC, and the like.
In certain embodiments, because the full face masks are made of one type of material or a different material with similar characteristics, they can be re-sterilized or cleaned with one type of sterilizing or cleaning agent or combination of sterilizing or cleaning agents.
In certain embodiments, the relatively flat design of the full face mask prior to folding allows it to be conveniently carried by storing it in a container (e.g., a bag, briefcase, or backpack) so that it can be easily removed and assembled into a functional face mask when in use.
In certain embodiments, the full face mask is made of lightweight plastic so that it can be worn for extended periods of time.
In certain embodiments, the plastic used to form the full face mask is inert so as not to cause any allergic problems to the wearer.
In certain embodiments, there are rectangular, semi-conical, cylindrical, spherical or square head contact protrusions on the full face mask that contact the forehead, which allow air to flow and circulate over the face for comfort to the wearer.
It can thus be seen that an improved face mask and full face mask have been disclosed that eliminate or at least reduce the disadvantages and problems associated with prior art products. The airflow deflection protrusion of the mask deflects the airflow away from the wearer when the airflow guide tab is positioned. When the top of the full face mask is bent towards the forehead of the wearer by the folded configuration, a large portion of the forehead and the skull may be protected. This reduces the chance of bacteria, viruses or other harmful substances depositing on the forehead, the front of the head and the hair of the wearer. In addition, the folding structure is simple, so that the full face mask is easy to manufacture and assemble.
While the invention has been described in terms of certain embodiments, other embodiments apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the invention is limited only by the following claims.
