Description

  The present invention relates to a facial mask including a pair of adjustable ear hooks.

  Facial masks that cover a wearer's nose and mouth can be used for a variety of purposes, such as to prevent the spread of bacteria and / or to filter air. Many configurations have been introduced to assist users in wearing and securing facial masks. Traditional masks are strips tied behind the face, sticky or elastic strips that form a loop behind the face or around the ears ("ear loop configuration"). To use. Each configuration has advantages and disadvantages.

  Ear-hook configurations are often preferred over configurations with adhesive bands. Adhesive bands can be painful when peeling or removing the adhesive band from the wearer's skin. Further, the formation of a loop around the wearer's ear is often preferred over the wearer's head wrapping configuration. The former is usually easy to put on and take off, and is less likely to get entangled in the wearer's hair.

  Typically, the ear hook structure is formed of an elastic material to accommodate different sizes of the wearer's head. For example, U.S. Pat. No. 4,941,470 discloses a facial mask that is held in place by a pair of ear hooks. The fabric panel and the ear hook of the mask are joined together by heating the joint between the fabric panel and the free end of the ear hook. A drawback of this conventional "one-size fits all" configuration is that the mask and ear ears may not fit properly.

  In order to solve this problem, a structure in which the ear hook can be adjusted, as disclosed in US Published Patent Publication No. 2015/0335080 and US Pat. No. 5,819,731, has been devised. In the former, each of the ear hooks may be formed from an elongate member. "Take-up loops" are formed when the respective intermediate portions of the elongated members are inserted through the holes in the mask panel. The slider along this loop (rewind type loop) or the elongate member can provide an adjusting function to increase or decrease the size of the ear hook. The latter employs the use of an adjustable band that extends around the front of the mask and then around the back of the neck after forming a loop around the wearer's ear.

  Although the above-mentioned published patent publications and patents provide methods for making earplugs adjustable, their masks require a great deal of effort by the wearer to ensure a proper fit. .. Furthermore, those masks may require additional objects (ie, additional components for use). Therefore, there is a need for a less hassle-free means of adjustable earplugs that allows the earplugs to be adjustable and minimizes the objects needed to achieve this functionality. There is.

  The present invention recognizes that there is a need for ear hooks for face masks that can be adjusted to fit the size of the wearer, thereby ensuring comfort and proper sealing. Wearing the mask should be quick and easy. Moreover, the mask should be adjustable without the need for additional objects or components. The wearer should be able to place the mask over his or her face and easily adjust the size of the earrests so that the mask is safe and comfortable. Other masks have multiple components that fit over the ears, but with a sophisticated, customizable mask fit without sacrificing the firm fit of the mask on the wearer's face, Or, there is no intuitive and easy-to-use solution.

  The following summary is provided to facilitate an understanding of some of the innovative features unique to the disclosed embodiments, and is not intended to be provided as a complete disclosure. A complete understanding of various aspects of the embodiments disclosed herein can be gained by referring to the entire specification, claims, drawings, and abstract.

  The present invention relates to a mask with adjustable ear hooks formed from elastic fabric. Each earrest may have a pre-cut opening through which the wearer can insert one of his / her ears. In the preferred construction, the mask is constructed of an elastic fabric that is durable and comfortable for the wearer.

  More specifically, the present invention has (a) a central portion for filtering exhaled air and inhaled air, (b) a first ear hook having a tearable area, and (c) a tearable area. It includes a single piece face mask composed of a second ear hook. The first ear hook and the second ear hook are located on a side surface side of the central portion, and further, each of the first ear hook and the second ear hook is arranged such that the wearer has a first ear hook around the ear. And an opening for fixing each of the ear hooks and the second ear hooks. The wearer can increase the size of the first ear hook by tearing or cutting the tearable area of the first ear hook. Further, the wearer can increase the size of the second ear hook by tearing or cutting the tearable area of the second ear hook.

  The tearable area is perforated to assist the wearer in increasing the size of the opening by tearing or cutting. In addition, the tearable region may include one or more notches that assist the wearer in increasing the size of the opening by tearing or cutting. The plurality of notches may provide feedback to the wearer by increasing the force required to cause further tearing from each of the plurality of notches. The woven material and the notches can prevent the tearable area from further tearing after the face mask is applied. A portion of the tearable area may be partially torn to assist the wearer in identifying the tearable area and further reduce resistance to tearing. In alternative configurations, the first ear hook and the second ear hook may be elastic cords, bands, strings, or threads.

  The invention also includes a facial mask composed of a central air filtering portion and two pre-cut ear-hook regions flanking the central air filtering portion. Each of the ear-hook areas may include one or more perforated sections. The wearer can increase the size of the ear-hook area by tearing or cutting the one or more perforated sections. The two pre-cut ear hook regions may be square, triangular, or elliptical in shape. In addition, each portion of the perforated section is partially torn to assist the wearer in identifying the perforated section and further to reduce resistance to tearing. May be. The perforated section may also include one or more notches that assist the wearer in tearing or cutting.

  The present invention also includes a facial mask that includes a central air filtering portion and a first ear hook and a second ear hook that are located on a side surface side of the central air filtering portion. In this structure, each ear hook is composed of a cord. Each cord includes a midpoint portion, an upper twist thread, and a lower twist thread. The upper and lower strands are connected to a central air filtering section. One or more melting zones are formed in the midpoint zone, in which the yarns are fastened to each other from the upper side and the lower side. The wearer can increase the size of the earhook by tearing, peeling, or cutting the fused portion to separate the upper and lower threads from each other. The string may be composed of strings or threads.

  Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which by way of example illustrate the principles of the invention.

  The present invention includes a mask having an adjustable ear hook formed from a flexible and / or elastic fabric. FIG. 1A shows a mask 100 with ear hooks according to one aspect of the present invention. The central portion (shaded portion) may be constructed of conventional mask material that filters air. In normal use, this part covers the wearer's mouth and nose. The central portion can filter inhaled air and protect the wearer from dust, bacteria, or certain substances in the air. The central portion can also filter the exhaled air and prevent the spread of bacteria (eg, bacteria and viruses) from the wearer to others. The mask may be formed for one-time use (ie, disposable).

  FIG. 1B shows the ear hook of the mask 100 in more detail. Each earrest includes a pre-cut opening 120 for securing over or around the wearer's ear. The size of each earrest is adjustable to accommodate the size of the wearer's head. In the preferred configuration, the tearable portion comprising the plurality of notches 110 is adjacent to the pre-cut earpiece. The tearable portion allows the wearer to easily increase the size of the ear hook to the appropriate size by tearing or cutting the fabric.

  As shown, the plurality of notches form a tearable region and further extend away from the center of the mask. The plurality of notches allow for tearing along a pre-defined area (ie, tear line). Also, the plurality of notches can prevent further propagation of the tear when a force is applied to the mask. That is, the force to put on the mask will not further tear the area. Instead, such forces will be directed away from the tearable area. This prevents inadvertent increase in size or tearing of the ear hook during normal wear. It also prevents the user from performing more tears than necessary (i.e., "runaway tears") and forming holes that are larger than needed. Also, the fabric around each notch, such as a seam or a thinner fabric, can be reinforced.

  Also, the multiple notches in the ear hook can provide feedback to the wearer as the wearer tears to increase the size of the ear hook. This feedback can provide the user with an indication to stop further tearing. More specifically, the feedback stops / stops tear transmission by redirecting the force away from the tear line.

  For example, the initial tear may be one that requires little effort from the user. After the tear reaches the first notch, more force is required to make an additional tear to the second notch. This pattern is similar when the wearer tears from the second notch to the third notch. This feedback is provided both during manual tearing and when using tools to cut the material. The wearer can continue to tear until the mask fits comfortably and, moreover, fits snugly enough to stay in place.

  Also, the pre-defined sections, such as the notches on each side of the mask, ensure consistent adjustments when replacing the mask. When the wearer replaces the mask, he / she can quickly adjust the size of the ear-hook of the new mask to match the size of the previously worn mask. For example, assume that the mask fits properly on the wearer when the size of each earhook has been increased to the first notch. In this case, the wearer can quickly make adjustments by tearing each side up to the first notch before wearing the mask.

  FIG. 1C also shows the ear hook in more detail. In this alternative configuration, a tearable portion comprising a plurality of perforations 130 is adjacent to the ear hook 120. FIG. 1D illustrates a configuration having a tearable region with both multiple perforations and multiple notches 135. The tearable area may be marked by a dashed line, for example to make it easier for the wearer to find.

  To increase the size of the earplug, the wearer may perform a tear or cut along the notches, perforations, or lines described above to reduce the tension of the earhook when the mask is worn. Can be reduced. This task can be carried out in a stepwise manner, up to the point where it is comfortable for the wearer, while at the same time providing an appropriate amount of tension to secure the mask.

  A line may be printed along the tearable area to indicate where the earhook should be torn. In another embodiment, the line is perforated to facilitate the tearing action of the fabric and to control the direction of the tear. In other embodiments, this line is curved. In yet another embodiment, there are two or more sections (not shown) to be torn.

  In alternative configurations, the tearable portion may be physically modified (eg, folded or scored). Such a configuration may be practical when constructing a mask using a plurality of specific types of materials. When using multiple notches or marks, this modification can make the tearable area more discoverable to the wearer. In addition, this modification can help maintain tear along the tearable area while preventing other areas of the earhook from tearing.

  The fabric of the ear-hook portion of the mask may be formed from a thin elastic polymer layer of high elasticity sandwiched between one or more layers of woven fabric. The fabric need not have the high elasticity or yield strength of the elastic polymer layer, but is woven in a manner that allows it to accommodate stretch. In addition, the elastic fabric is easily tearable without any cutting tool and does not fail when the mask is worn (ie, it does not tear or tear). ) It may be formed and / or designed of a material that is sufficiently strong.

  The plurality of notches may be marked to indicate both the tear direction and the stopping point. The distance between the notches is large enough that the tension on each tear is greatly reduced, while at the same time short enough that it does not interfere with the tearing operation. As shown in FIG. 1B, the plurality of notches 110 may be equidistant from each other or may be substantially equidistant from each other. In an alternative configuration, the plurality of notches may be spaced apart from each other as is suitable for improving mask design and use. For example, the additional notches in the ear hook may be spaced closer together. The first few notches may allow the wearer to quickly adjust the size of the ear hook for use. The remaining notches may allow fine tuning for maximum comfort (not shown).

  FIG. 2A shows an alternative shaped earhook configuration having a triangular shape 140. Also, the pre-cut openings have a triangular shape 150. Here, the tearable region has a plurality of perforations and notches 135. The tearable region extends horizontally away from the center of the mask. The wearer can tear along the tearable area to increase the size of the ear hook. This shape can be superior to conventional shapes in terms of comfort and improved fit.

  FIG. 2B shows an earhook 160 having a curved shape that may be more ergonomic for the wearer. Here, the pre-cut ear hook extends from the horizontal direction in a direction inclined by about 45 degrees from the horizontal direction. The pre-cut openings 165 are similarly shaped. The tearable area 135 follows the angle of the pre-cut aperture (approximately 45 degrees from horizontal). This configuration is based on the wearer's head size, his / her facial features, and whether he / she prefers to wear the mask at a lower angle than a normal wearer. A more preferable configuration can be obtained. As with other configurations, the wearer can tear along the tearable area 135 to increase the size of the earhook. Here, the tearable region 135 includes a plurality of perforations and notches. In this configuration, the size of the ear hook increases at an angle rather than horizontally.

  FIG. 2C shows an alternative shape of earpiece 170 having an elliptical shape 180 pre-cut region. FIG. 2D illustrates a similar configuration of ear hook 190 having a tapered elliptical pre-cut region 210. In both configurations, the tearable region 135 comprises a plurality of perforations and notches for tearing.

  For configurations with multiple notches (as shown in FIG. 1D-3), the wearer tears along the marked line (dashed line) to the first notch to determine the size of the earhook. To increase. If the mask feels tight, he / she can tear further along the line to further increase the size of the earhook. Although three notches are shown in the figure, the configuration may include more or less notches.

  FIG. 3 shows the earhook of FIG. 2C with a partially pre-tearable tearable area 145. The pre-tear region provides at least two benefits. First, the wearer can provide a prominent starting point for tearing the mask. Continued tearing along the notch, mark, or perforation line can be more intuitive since the region has already been partially torn. Second, the pre-cut section allows the elastic fabric to fold when worn on the ear. This can increase the surface area of the elastic fabric that contacts the ears, and thus reduce the amount of pressure on the surface. Finally, this allows the user to wear the mask for a longer period of time, as the mask does not have to be adjusted or removed due to ear discomfort. Such pre-tear areas may or may not be marked.

  In an alternative embodiment, the mask 200 may include ear hooks formed from cords, strings, threads, or similar elastic or flexible materials, as shown in FIG. 4A. Good. In the preferred configuration, the earhook is formed from a single elastic string 220 joined to one side of the central portion of the mask at at least two points 225. One or more portions of the string are “bonded” to each other at a bond point 230. The user can increase the length of the string (and the size of the earhook) by tearing the area at one or more junctions 230.

  The junctions of the strings that are joined together act as tearable regions. The wearer wears the mask by inserting the ears into the ear hooks, which results in tension in the string. The size of the ear hook can be increased by peeling or tearing each of the junctures of the string with or without the aid of a tool. Therefore, the user can effectively increase the length of the cord (and the size of the ear hook) by peeling or tearing the joining points one by one. The user can do so while maintaining sufficient tension to secure the mask securely on his / her face until the mask is comfortable. In FIG. 4A, two splice points 230 are shown on the lace 220, but the earhook may have more than two splice points. In an alternative configuration, the lace may have a single juncture (not shown). The juncture may extend substantially along the length of the ear hook. The user may peel off the thread and increase the size of the ear hook.

  FIG. 4B shows a similar earhook configuration 200 formed from laces, strings, threads, or similar elastic or flexible material 200. The ear hook is joined to the central portion of the mask at two points 225. The points 230 of the strings joined together act as tearable areas. Here, there is an upper joining point (first tearable area) and a lower joining point (second joining area). The user can increase the length of the string (and the size of the earhook) by tearing these areas. This configuration allows adjustments to accommodate the wearer's head, his / her facial features, and whether he / she prefers to wear the mask at larger / smaller angles.

Use of the Invention to Improve the Fit of a Disposable Mask In a typical use of the invention, the wearer inserts his or her ear into the first earhook. If desired, the wearer can increase the size of the ear hook by performing a tear along the tearable section adjacent the ear hook. More specifically, the pre-defined section of the ear hook (ie, the tearable area) is tearable or severable to effectively increase the size of the ear hook opening, which allows The tension from the hanging can be reduced. The tearable area may comprise a plurality of notches and / or perforated areas. The wearer increases the size of the earhook by tearing the tearable area to accommodate the size of his / her head.

  The wearer then inserts his or her ears into the second earhook. The second ear hook also has a tearable area. As described above, the wearer can increase the size of the second ear hook by performing the tearing as described above.

  After placing the mask around both ears, the wearer can make additional adjustments (ie, tearing can increase the size of one or both of the earhooks). The wearer can adjust the size of the earhook so that the mask fits comfortably and, moreover, fits tightly on his / her face. The wearer can continue to increase the size of the earrest to ensure that the mask is both comfortable and tight enough to be used.

  In a preferred configuration, the mask is intended for single use (ie, disposable). Thus, the wearer can be familiar with how many notches should be torn in each side for an ideal fit. Accordingly, the wearer can quickly and easily make the size of each ear hook a preferable size each time the wearer uses it.

  It will be appreciated that variations of the above or other features and functions, or alternatives thereof, can be combined with other systems or applications. Various foreseeable or unexpected alternatives, modifications, variations, or improvements made therein by those skilled in the art will also fall within the scope defined by the following claims.

  While the current embodiments of the invention have been described in considerable detail and comprehensively to cover possible aspects, other versions of the invention are also possible to those skilled in the art. You can recognize that there is.
