Definitions
- the invention relates to filter masks which isolate both the mouth and nostrils of a wearer from the surrounding environment. More particularly, the invention relates to a conforming, collapsible filter mask which requires only a headband to secure the filter mask to the wearer's head.
- filter masks are often used to prevent substances exhaled by the wearer from entering the surrounding environment.
- the same mask may also be used to protect the wearer from inhaling harmful microorganisms.
- One of the more common applications of filter masks in the medical arts is the wearing of masks by a surgical team while performing surgical procedures.
- a mask worn during surgical procedures desirably provides proper air filtration while still being comfortable for the wearer who may be wearing the same mask for several hours.
- the full benefits of the filter mask will not be realized if inhaled or exhaled air is allowed to leak around the edges of the mask when held against the wearer's face.
- a mask that is relatively quick and easy to place on the face, and that will remain in the proper position while the wearer continues his or her ordinary activities. It is further desirable to design a mask that is compact. Generally, a flat storage configuration provides for the most compact storage. Moreover, it is desirable that a mask be economical, since most users of filter masks dispose of the mask after limited use.
- the present invention includes a disposable respirator which defines an area surrounded by a periphery, the disposable respirator extending across a wearer's nose bridge, across each of the wearer's cheeks, and underneath the wearer's chin for covering the nose and mouth of the wearer.
- the disposable respirator includes a filter body comprising a non-elastic material defining a first area, and a first stretch-panel having an outer edge defining a portion of the mask periphery, the first stretch -pan el defining a second area.
- the first stretch-panel is an elastic material. The area of the first stretch-panel is less than the area of the filter body.
- the respirator is made with a filter body sized to fit over the mouth and nose of the wearer, the filter body having a top edge arranged to extend across the nose and cheeks of the wearer, a bottom edge arranged to extend along a wearer's jaw line, and a seam edge arranged to extend between the wearer's nose to the wearer's chin; and a triangular elastic panel attached to the bottom edge of the filter body, wherein the stretch-panel is arranged to fit underneath the wearer's chin.
- the respirator is made from a filter body sized to fit over the mouth and nose of the wearer, the filter body having a top edge arranged to extend across a nose and upper cheeks of the wearer; a bottom edge arranged to extend along lower cheeks and underneath a chin of the wearer, wherein the bottom edge has two spaced apart notched portions; and a seam edge arranged to extend between the wearer's nose to the wearer's chin; and a stretch-panel disposed within each of the of notched portions and attached to the filter body.

- Attach and its derivatives refer to the joining, adhering, connecting, bonding, sewing together, or the like, of two elements. Two elements will be considered to be attached together when they are integral with one another or attached directly to one another or indirectly to one another, such as when each is directly attached to intermediate elements. "Attach” and its derivatives include permanent, releasable, or refastenable attachment. In addition, the attachment can be completed either during the manufacturing process or by the end user.
- Connect and its derivatives refer to the joining, adhering, bonding, attaching, sewing together, or the like, of two elements. Two elements will be considered to be connected together when they are connected directly to one another or indirectly to one another, such as when each is directly connected to intermediate elements.
- Connect and its derivatives include permanent, releasable, or refastenable connection. In addition, the connecting can be completed either during the manufacturing process or by the end user.
- disposed on is intended to mean that one element can be integral with another element, or that one element can be a separate structure bonded to or placed with or placed near another element.
- Layer when used in the singular can have the dual meaning of a single element or a plurality of elements.
- spunbonded fibers refers to small diameter fibers which are formed by extruding molten thermoplastic material as filaments from a plurality of fine, usually circular capillaries of a spinneret with the diameter of the extruded filaments then being rapidly reduced to fibers as by, for example, in U.S. Patent No. 4,340,563 to Appel et al., and U.S. Patent No. 3,692,618 to Dorschner et al. , U.S. Patent No. 3,802,817 to Matsuki et al., U.S. Patent Nos. 3,338,992 and 3,341 ,394 to Kinney, U.S. Patent No. 3,502,763 to Hartman, and U.S.
- Spunbond fibers are generally continuous and have diameters generally greater than about 7 microns, more particularly, between about 10 and about 20 microns.
- "Stretch bonded laminate” refers to a composite material having at least two layers in which one layer is a gatherable layer and the other layer is an elastic layer. The layers are joined together when the elastic layer is extended from its original condition so that upon relaxing the layers, the gatherable layer is gathered. Such a multilayer composite elastic material may be stretched to the extent that the non- elastic material gathered between the bond locations allows the elastic material to elongate.
- One type of stretch bonded laminate is disclosed, for example, by U.S. Patent No.
- “Necking” or “neck stretching” interchangeably refer to a method of elongating a nonwoven fabric, generally in the machine direction, to reduce its width (cross- machine direction) in a controlled manner to a desired amount.
- the controlled stretching may take place under cool, room temperature or greater temperatures and is limited to an increase in overall dimension in the direction being stretched up to the elongation required to break the fabric, which in most cases is about 1.2 to 1.6 times.
- the web retracts toward, but does not return to, its original dimensions.
- Ultrasonic bonding refers to a process in which materials (fibers, webs, films, etc.) are joined by passing the materials between a sonic horn and anvil roll.
- An example of such a process is illustrated in U.S. Patent No. 4,374,888 to Bornslaeger, the content of which is incorporated herein by reference in its entirety.
- Thermal point bonding involves passing materials (fibers, webs, films, etc.) to be bonded between a heated calender roll and an anvil roll.
- the calender roll is usually, though not always, patterned in some way so that the entire fabric is not bonded across its entire surface, and the anvil roll is usually flat.
- the percent bonding area varies from around 10 percent to around 30 percent of the area of the fabric laminate.
- thermal point bonding holds the laminate layers together and imparts integrity to each individual layer by bonding filaments and/or fibers within each layer.
- Elastic refers to any material, including a film, fiber, nonwoven web, or combination thereof, which upon application of a biasing force in at least one direction, is stretchable to a stretched, biased length which is at least about 110 percent, suitably at least about 130 percent, and particularly at least about 150 percent, its relaxed, unstretched length, and which will recover at least 15 percent of its elongation upon release of the stretching, biasing force.
- a material need only possess these properties in at least one direction to be defined as elastic.
- Recover refers to a contraction of a stretched material upon termination of a biasing force following stretching of the material by application of the biasing force. For example, if a material having a relaxed, unbiased length of one (1 ) inch is elongated 50 percent by stretching to a length of one and one half (1.5) inches the material would have a stretched length that is 150 percent of its relaxed length. If this exemplary stretched material contracted, that is recovered to a length of one and one tenth (1.1 ) inches after release of the biasing and stretching force, the material would have recovered 80 percent (0.4 inch) of its elongation.
- Polymer generally includes but is not limited to, homopolymers, copolymers, such as for example, block, graft, random and alternating copolymers, terpolymers, etc. and blends and modifications thereof. Furthermore, unless otherwise specifically limited, the term “polymer” shall include all possible geometrical configurations of the molecule. These configurations include, but are not limited to isotactic, syndiotactic and random symmetries.
- the present invention is a respirator 10 that is generally constructed from a filter body 12 and one or more stretch-panels 14, exemplified by panels 14A and 14B in FIGS. 1-10.
- respirator 10 preferably has the general shape of a cup defining an opening 11 that is generally against the wearer's face when worn (see, FIG. 3).
- the filter body portion of the mask 10 is preferably held away from the wearer's nostrils and mouth.
- Such "off-the-face" style masks provide a breathing chamber to permit cooler wear and easier breathing.
- the respirator is intended to be disposable, that is, used for a limited period of time and disposed of rather than washed or otherwise rejuvenated for reuse.
- the stretch-panel(s) 14 may be located at various locations of the respirator providing that it coincides with the mask periphery 16.
- a stretch-panel 14 at the mask periphery 16 may desirably stretch in a direction that is approximately tangent or parallel to the periphery 16 so that the periphery 16 can selectively increase in size as needed. More detailed non-limiting examples of the present invention are described below.
- a first exemplary embodiment of the respirator 10, shown in FIGS. 1-5 may be constructed from a unitary filter body 12 and a single stretch-panel 14, specifically referred to as panel 14A.
- filter body 12 is formed from one of more layers of material as described below.
- the filter body may be cut into a blank that is symmetric about a fold line 18. A fold is formed at fold line 18 when the constructed mask 10 is in a flat configuration (see FIGS. 1 and 2).
- FIGS. 1 and 2 instead of the unitary body blank shown in FIG. 2, it is contemplated that two or more separate parts may form the filter body 12.
- the overall shape of filter body 12 is defined by a top edge 22 flanked by a pair of side edges 24, which together extend across the nose bridge and along the cheeks of the wearer; a pair of bottom edges 25 that when joined together, extend along the lower jaw of a wearer (see FIG. 4); and a pair of seam edges 26 that converge together from the inner end of each bottom edge 25 to the lower end of the fold line 18.
- Each edge 22, 24, 25 and/or 26 may be curved as shown, or a may have an angular configuration. It is desirable to have the some type of headband attachment structure located near each junction of edges 22 and 24, referenced as points "A" and "B" in FIG. 2.
- side edge 24 may be shaped to define tab members 27, used to accommodate a headband attachment structure as described below.
- Respirator 10 has an outer surface area (viewable when the mask is worn), and an opposite inner surface area.
- the outer surface area of the respirator 10 is defined as the sum of the filter body 12 outer surface area and the stretch-panel 14A outer surface area, minus any margins used to connect these components together.
- the outer surface of stretch- panel 14 is the sum of the individual outer surface areas for each stretch-panel.
- the type of filter materials and/or media used may depend on the intended end use of the respirator by a consumer. For instance, different uses will require different levels of filtration, which is beyond the scope of the present invention. Desirably, the combined layers of the filter body provide structural stiffness such that mask 10 does not collapse against the nose and mouth while being worn.
- suitable materials for the filter body 12 may include one or more layers of material. In one embodiment, there are two layers of material. Outer layer 60 may be formed from a material that is (a) gas permeable such that it permits air to pass through filter body 12 in both directions, and (b) liquid impermeable such that it prevents liquid from passing through layer 60 in at least one direction. Layer 60 is preferably arranged to help prevent the passage of liquids from the exterior of mask 10 to the interior of mask 10.
- filter body 12 is a three layer structure that includes an outer mask layer 60, an inner mask layer 62, and a middle layer (not shown).
- filter body 12 may include outer mask layer 60 that is constructed from a spun-bonded polypropylene that may have a 30.5 gsm basis weight.
- Alternative materials for outer mask layer 60 include, but are not limited to, thermally-formed polyester-bonded carded web, bi-component and/or powder bonded polyethylene or polypropylene nonwovens, wet-laid nonwovens, cellulosic tissue, or a spunbond polyester. The basis weight of these materials may range from about 15 to about 200 gsm.
- Inner mask layer 62 may be constructed from the same materials as layer 60, or a in the alternative, a composite made from bicomponent polyethylene and polypropylene, or a composite made from bicomponent polyethylene and polyester. Layer 62 may also be constructed from a polyester and/or polyethylene material or a cellulosic tissue. In one particular embodiment, layer 62 is a thermally formed blended fiber bonded carded web. Desirably, layer 62 may have a basis weight of about 17 gsm.
- the middle layers of filter media which may be disposed between outer mask layer 60 and inner mask layer 62, can depend on the degree and type of filtration required by the wearer.
- Suitable mediums for the middle layer include, but are not limited to, melt-blown polypropylene, extruded polycarbonate, melt-blown polyester, or melt-blown urethane, bicomponent spunbond and/or an expanded polytetrafluoroethylene (PTFE) membrane.
- the middle layer may be a filtrating material such as electret-treated meltblown polypropylene having a basis weight of roughly 70 gsm, or alternatively, in the range of about 30 to about 120 gsm.
- the middle layer may be a combination of lighter weight layers which together, add up to the desired basis weight.
- the middle layer may be a laminate formed from a two plies of 50 gsm sheets.
- Stretch-panel 14A may have various shapes. For example, as seen in FIG. 2, stretch-panel 14A is basically a triangular wedge. It is contemplated that stretch- panel 14A may be asymmetric or symmetric as shown. Further, stretch-panel 14A may be a truncated ovoid, a rectangle, or even a decorative shape such as a lightning bolt. If there is more than one stretch-panel (as seen in latter embodiments of the present invention) they do not need to be identical shapes. Regardless of the exact shape of any stretch-panel 14, it will characteristically have an edge, such as edge 28, coincides with the periphery 16. Because the stretch-panel is designed to stretch, the shape desirably provides adequate area adjacent the edge 28, and an adequate length for edge 28, so as not to prevent or limit stretching.
- stretch-panel 14 is symmetric in shape and has a pair of sides 25' which correspond in length to the bottom edges 25 on filter body 12. Desirably, the length of side 25 is about equal to the length of side 25'. Most desirably, the triangular shape is truncated to create a short side 29. The purpose of truncation is to lessen the amount of material that comes together when seam 26 is created, specifically, at the outer end 30 of seam edges 26. This reduction of material will create a cleaner and more flexible seam.
- stretch-panel 14 is desirably constructed from a material that is stretchable in at least one direction, and air impermeable.
- stretchable describes a material that can stretch yet substantially recover to its initial pre-stretched dimension.
- air impermeable means that for all practical purposes, the wearer cannot breathe through the stretch-panel 14.
- One direction of stretch will substantially align with the periphery edge 16. If periphery edge 16 is a straight edge, it is desirable that the stretch direction be about parallel with periphery 16. If periphery 16 is a curved edge, it is desirable that the stretch direction be about parallel with a tangent of periphery 16 taken at about the midpoint of a stretch-panel edge 28.
- Suitable materials for the stretch-panel 14 include, but are not limited to, films, nonwovens, or laminates that may include an elastic component such as natural rubber latex, urethanes, elastic block copolymers (e.g. KRATON ® from Kraton
- Laminates may be in the form of necked materials such as necked bonded nonwovens, or single- or dual-faced elastic film laminates such as stretch bonded laminates. Desirably, these stretch-panel 14 materials can be stretched to at least about 30% of an original length. However, it may be more desirable that such materials may be stretchable up to about 100% of an original length, and most desirable that such materials may be stretchable up to about 200% of an original length.
- the stretch- panel material may be air impermeable, or have a greater filtration performance (e.g. higher density, less porous, etc.) throughout the entire range of stretch than filter body 12.
- top edge 22 of the mask 10 inside of top edge 22 of the mask 10, there may be an elongated malleable strip 52 as shown in FIGS. 1 -3 and 5.
- Malleable strip 52 known in the respirator art, is provided so that top edge 22 of mask 10 can be configured to closely fit the contours of the nose of the wearer. In order to reduce
- malleable strip 52 is preferably positioned at about the center of top edge 22 and has a length in the range of about 40 percent to about 70 percent of the total length of the top edge 22, defined as the distance between points A and B (see FIG. 2).
- Malleable member 52 is preferably constructed from an aluminum-alloy strip with a rectangular cross-section, but may also be a moldable or malleable metal or plastic member. Desirably, strip 52 is located between layers 60, 62, and may be held in position by adhesive, or by a border that is stitched or heat sealed to closely surround strip 52 to prevent slippage. Malleable strip 52 may be used in any embodiment of the present invention.
- the present invention may further include devices for attaching mask 10 to the face of the wearer. Any type of conventional attachment devices are within the scope and spirit of the invention.
- the mask 10 may include at least one strap for securing about the wearer's head.
- the mask may include straps extending from the top and bottom edges thereof for being tied around the wearer's head (not shown).
- the mask may include loops for being fitted over the ears of a wearer (not shown).
- a vast number of attaching devices are well known to those skilled in the art and any manner of such device may be incorporated in the present invention.
- the attaching device allows a wearer to place the respirator 10 onto the wearer in a manner that no gapping between the wearer's face and the periphery 16 occurs accidentally.
- a simple headband attachment device is a strap 42, and one of the ways to adjustably connect the headband strap 42 to a respirator 10 is through an aperture such as a slit 44.
- additional clips, snaps, loops, hook and loop, buttons, or other mechanical fasteners may be used to selectively and/or adjustably attach a headband straps 42 to respirator 10.
- headband straps 42 are preferably constructed from resilient polyurethane, but may be constructed from elastic rubber or a covered stretch yarn.
- the covered stretch yarn may consist of an elastomeric material wrapped with nylon or polyester.
- headband straps 42 may be double knitted headbands such as circle knitted polyester/LYCRA or nylon/LYCRA. Any flexible strip that is tolerated by the wearer may be used as a strap.
- the assembly of mask 10 is as follows.
- Filter body 12 may be formed by cutting and connecting layers 60, 62 and optional middle layer (or other layers) to each other along margins adjacent the periphery 16. Such connections are preferably provided along top edge 22 and side edges 24, respectively.
- the corresponding margins 65 may be formed by sewing, glue, heat sealing, welding, thermal point bonding, ultrasonic bonding and/or any other suitable connection procedure.
- a margin 67 may surround slit 33 for structural reinforcement. After the margins are formed on the filter body, the body-facing surface of the mask may be brought together by folding the blank about fold line 18.
- the stretch-panel edges 25' are aligned with the filter body edges 25 and bonded together to form outwardly facing fin seams 71.
- the edges 26 may be further be bonded together in a like manner to create an outwardly facing fin seam 73.
- the junction between seams 71 and 73 is bonded to prevent air leakage.
- Top edge 22, side edge 24, and exposed edge 28 of the stretch-panel 14A cooperate with each other to define the periphery 16 at the opening 11 of mask 10.
- each of the bonded seams 71 , 73 share the characteristic of being air impermeable. Thought it is contemplated that lap seams or other connection methods may be used. It is most desirable that seams 71 and 73 be created via an air impermeable bond such as a pressure or ultrasonic bond.
- a second exemplary embodiment of the respirator 10, shown in FIG. 6, has not one, but two stretch-panels 14, designated as "14B." Of course, more than two stretch-panels may make up the overall surface area of mask 10. However, if stretch-panel 14 is air impermeable, it may not be desirable to incorporate too much stretch-panel material into the mask configuration as the mask 10 breathability could be compromised.
- filter body 12 differs from that shown in FIG. 2 in that it is larger.
- the filter body 12 is symmetric about the fold line 18. Because there is no stretch- panel 14A located under the chin, the seam edges 26 extend all the way to edges 24. Seam edges 26 extend between points "C" and "E.”
- a fin seam 73 (or other seam type mentioned previously) formed by connecting the seam edges 26 together. Desirably, fin seam 73 is air impermeable as in the previous embodiment.
- stretch-panels 14B may be triangular as shown, or the other various shapes mentioned. Desirably, each stretch-panel is located over the wearer's cheeks in a symmetric configuration. In the embodiment of FIG. 6, each stretch-panel 14B is located between the headband structure, tab 27 at about point "D" and the end of seam 26 at point "C.”
- the stretch-panel 14B has an edge 28 that is shorter in length than the distance 80 between points "C" and "D.” Desirably, the length 82 of edge 28 is between about 0.2 to about 0.33 the length of distance 80. More desirably, length 82 is less than about 0.25 to about 0.5 of the length of distance 80.
- the side panels 14B may be positioned to coincide with the tab member 27, and may have strap 42 or another headband attachment device connected thereto.
- the panels 14B as shown in FIGS. 6 and 8 may be elongated and meet at the edge 26. It is further contemplated in these embodiments; the stretch-panels 14B may be clear or translucent so that one may be able to see the wearer's mouth.
- seams 77 are outwardly facing fin seams created by an air impermeable bond such as a pressure or ultrasonic bond.
- a direction of stretch may coincide with the anticipated movement of the wearer. For instance, chewing may cause the wearer's jaw to move in direction 84 (see FIG. 6).
- the stretch direction of panel 14B may substantially align with direction 84. So as not to "lock up" the stretchability of panel 14B, the periphery may also be configured to align with the anticipated direction of movement.
- vent 100 is defined by a vent body having a fastening system attached thereto.
- the fastening system comprises at least one pull-strap fastening component 102 being formed integrally with a fastening component 104. Additional details regarding the vent 100 are disclosed in U.S. Patent Application, Serial 11/840031 , filed August 16, 2007, and incorporated herein to the extent it is consistent with the present invention. Other applicable exhalation vents are shown and described in U.S. Patent Application, Serial 11/840046, filed August 16, 2007, and incorporated herein to the extent it is consistent with the present invention.
- the mask may be configured as any number of conventional masks.
- the mask may be formed as a traditional molded cup or cone-shaped mask.
- Various configurations and shapes of masks are well known to those skilled in the art and any and all such conventional masks are within the scope and spirit of the present invention.
