BACKGROUND

1. The Field of the Present Disclosure
The present disclosure relates generally to face masks, and more particularly, but not necessarily entirely, to face masks with earloops.
2. Description of Related Art
A wide range of protective face masks are available on the market to accommodate various situations. Typically, most face masks comprise a panel dimensioned to cover a wearer's mouth and nostrils. The panel may serve as a filter to prevent undesirable contaminants and pathogens from being inhaled by the wearer. In this regard, the panel may comprise a fibrous filtering material with microscopic openings that is sandwiched between two air-permeable outer layers. The fibrous filtering material may filter contaminates while the two outer layers protect the fibrous filtering material. The two outer layers may be formed from a polymer-based fabric.
Various means are known to hold the panel in place over the user's mouth and nostrils. Most commonly, the panel is held in place with tie straps or earloops. For example, U.S. Pat. No. 4,941,470, granted Jul. 17, 1990 to Hubbard et al., discloses a face mask having a fabric panel held in place by a pair of earloops. The earloops are fabricated from a layer of elastically deformable heat malleable material. Each of the earloops are attached to the fabric panel on one side thereof with a heat formed seal. That is, the earloops and the fabric panel are bonded together by applying heat to the juncture of the free ends of the earloops and the fabric panel.
One drawback to the face mask of the '470 patent is that, other than the natural elasticity of the earloops, the length of the earloops are non-adjustable. This is problematic because the elasticity of the earloops does not adequately accommodate for the large disparity in the physical features of the wearers. That is, the earloops are manufactured as a one-size fits all, but the position of the ears on a head and the width and size of the nose varies between people in general, including between genders and between different ethnic groups.
Increasingly, wearers of face masks of the type disclosed in the '470 patent are becoming dissatisfied with the one size fits all approach. In particular, some wearers of face masks of the type disclosed in the '470 patent have complained that the earloops are too tight. Given that a typical wearer in a health care setting may don multiple masks in one day, tight earloops may cause discomfort, including headaches and ear pain. In some instances, wearers may unwisely choose not to wear the face masks because of the discomfort caused by the earloops. It would therefore be an improvement over the prior art to provide low-cost, disposable face masks with adjustable earloops that is easy to manufacture.
The prior art is thus characterized by several disadvantages that are addressed by the present disclosure. The present disclosure minimizes, and in some aspects eliminates, the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.
The features and advantages of the present disclosure will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the present disclosure without undue experimentation. The features and advantages of the present disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles in accordance with the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the disclosure as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the disclosure claimed.
In describing and claiming the present disclosure, the following terminology will be used in accordance with the definitions set out below. As used herein, the terms “comprising,” “including,” “containing,” “having,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps. It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
In an embodiment, the present invention comprises a method and apparatus for forming a face mask having a panel with a pair of adjustable earloops. The panel may comprise one, two, three or more layers. Preferably, but not necessarily, the panel may comprise an inner fibrous filtering material with microscopic openings that is sandwiched between two outer layers. The fibrous filtering material may filter contaminates while the two outer layers protect the fibrous filtering material and may also provide some filtering. The two outer layers may be formed from a polymer based fabric such that the edges of the two outer layers may be thermally bonded.
According to another aspect of the invention, each of the earloops may be formed from an elongated member. Each of the elongated members may comprise a first end and a second end. The first end and second end of each of the elongated members may be tacked to the panel, by heat bonding or in some other manner, such as stitching. In addition, according to another aspect of the invention, an intermediate portion of each of the elongated members may be threaded through a hole in the panel to form the earloop and a take-up loop. In this regard, each earloop may extend from the tacked first end of an elongated member to the hole in the panel and the take-up loop of the same elongated member may extend from the hole in the panel to the tacked second end.
According to another aspect of the invention, the earloops may be placed around a wearer's ears while the take-up loops may provide adjustability to increase or decrease the size of the earloops. In particular, the size of the take-up loops may be wearer adjustable to vary the size of their respective earloops. According to another aspect of the invention, the holes for the elongated members may be located in a heat bonded portion of the panels and may be slightly smaller than the diameters of the elongated members to provide a clamping, holding or compressing force on the elongated members.
Referring now to FIGS. 1 and 2, there is depicted a face mask 100 according to an embodiment of the present disclosure. The face mask 100 may comprise a panel 102. In an embodiment, the panel 102 may be substantially rectangular in shape and comprise a horizontal top edge 104, a horizontal bottom edge 106, a left vertical edge 108 and a right vertical edge 110. In an embodiment, a plurality of pleats 112 may extend horizontally with respect to the face of a wearer. It will be appreciated that the pleats 112 may expand when the face mask 100 is put on by a wearer. The pleats 112 may be formed by folding the panel 102 and tacking the ends of the pleats 112 by heat bonding or in some other manner, such as stitching.
In an embodiment, the panel 102 may comprise a plurality of layers. For example, the panel 102 may comprise a fibrous filtering material with microscopic openings that is sandwiched between two air-permeable outer layers. The inner fibrous filtering material may filter contaminates while the two outer layers protect the fibrous filtering material. The two outer layers may be formed from a fabric formed from a thermoplastic polymer. In particular, the two outer layers may be formed by melt blowing. (Melt blowing is a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor or takeup screen to form a fine fiberous and self-bonding web.) It will be appreciated that the panel 102 may comprise one, two, three, four, five or more layers. In an embodiment, the layers of the panel 102 may comprise a non-woven synthetic material. In an embodiment, one or more layers of the panel 102 may be formed from a woven material, such as cotton or the like. In an embodiment, the face mask 100 may be a one-time use mask or a reusable mask. For example, the face mask 100 may be washable.
In an embodiment, the layers of the panel 102 may be joined using a heat bonding process. As known to those of ordinary skill, heat bonding involves applying heat and pressure to the layers of the panel 102. The portion of the layers subjected to the heat and pressure may then melt together. In particular, as shown in FIG. 1, heat bonds 114 may be formed along a perimeter of the panel 102 to join the various layers together and to form the pleats 112.
In an embodiment, elongated members 120 be attached adjacent the left vertical edge 108 and the right vertical edge 110, respectively. Each of the elongated members 120 may have a first end 122 and a second end 124. The first end 122 and the second end 124 of each of the elongated members 120 may each be tacked to the panel 102. In an embodiment, the first end 122 and the second end 124 of each of the elongated members 120 may be joined to the panel 102 by heat bonding. In an embodiment, the first end 122 and the second end 124 of each of the elongated members 120 may be joined to the panel 102 by an adhesive. In an embodiment, the first end 122 and the second end 124 of each of the elongated members 120 may be joined to the panel 102 by stitching. It will be appreciated that the first end 122 and the second end 124 of each of the elongated members 120 may be joined to the panel 102 in any manner known to those having ordinary skill in the art.
In an embodiment, the panel 102 may comprise holes 126 for receiving an intermediate portion of the elongated members 120. It will be appreciated that holes 126 may be located anywhere on the panel 102, including in the top or bottom corners. That is, each of the elongated members 120 may pass through one of the holes 126. It will be appreciated that the holes 126 may be formed in a heat bonded portion of the panel 102. That is, a perimeter of the holes 126 may be heat bonded. It will be appreciated that the elongated members 120 may pass from front-to-back or back-to-front according to embodiments of the present invention.
In an embodiment, an intermediate portion of each of the elongated members 120 may be threaded through one of the holes 126 in the panel 102 such that the elongated members 120 each define an earloop 130 and a take-up loop 132. In this regard, each earlooop 130 may extend from the first end 122 of its elongated member 126 to one of the hole 126 and the take-up loop 132 may extend from the hole 126 to the second end 124 of the elongated member.
In an embodiment, the elongated members 120 may be deformable when placed under tension. In this regard, a diameter of each of the elongated members 120 narrows when the elongated members 120 are placed under tension. In an embodiment, the elongated members 120 may be elastically deformable. The elongated members 120 may be formed of a polymer.
It will be appreciated that the size of the earloops 130 may be adjustable to accommodate wearers of different sizes by varying the size of the take-up loops 132. A wearer may decrease the size of the earloops 130 by increasing the size of the take-up loops 132. A wearer may increase the size of the earloops 130 by decreasing the size of the take-up loops 132.
The sidewalls of the holes 126 in the panel 102 may be configured and dimensioned to apply a compressive force on the elongated members 120. In particular, because the holes 126 may be formed in a heat bonded portion of the panel 102, the heat bonded portion provides rigidity and reinforcement to the sidewalls of the holes 126 sufficient to provide a compressive force on the elongated members 120. Without the reinforcement provided by the heat bonded portion of the panel 102, the one or more layers forming the panel 102 would not have sufficient rigidity to provide a compressive force on the elongated members 120. A wearer may overcome the compressive force applied by the sidewalls of the holes 126 when adjusting the size of the earloops 130 by tensioning the elongated members 120, which decreases the diameter of the elongated members 120. When not under tension, the compressive force provided by the sidewalls of the holes 126 maintains the current position of the elongated members 120.
In an embodiment, the face mask 100 may be constructed by stacking the layers that form the panel 102. Then, at least one heated element may be pressed against an outer one of the layers, which causes the layers to “melt” together in the locations shown in FIG. 1 to form a heat bond. Holes 126 may then be formed through the panel 102 by a punch, needle, cutter, or in some other manner. Each elongated member 120 may be threaded through one of the holes and the ends 122 and 124 of the elongated members 120 may be heat bonded by a heating element or otherwise tacked to the panel 120. In an embodiment of the present disclosure, the second ends 124 of the elongated members 120 may be free or not tacked to the panel 102. In short, using essentially the same materials and construction techniques as the prior art face masks, the present invention provides a low-cost, disposable face mask with adjustable earloops as shown in FIG. 1.
