Field of the Invention
[0001] The present invention concerns a face mask retention system.
Brief Description of the Prior Art
[0002] As is commonly known, wearing a face mask is often considered cumbersome and uncomfortable,
especially when the face mask is worn for longer continuous periods.
[0003] Most face masks are retained on a wearer's head by elastic loops designed to fit
behind a wearer's outer ear or alternatively, with straps designed to be tied behind
a wearer's head.
[0004] While face masks with elastic loops fitting behind a wearer's ear are easy and fast
to put on, the elastic loops have the disadvantage that there is no suitable one size,
fit all and hence, the length of the loops often needs to be adapted to fit a wearer,
wherein such adaptation of the length in most cases results in a knot or a kind of
length regulator is present behind the outer ear of a wearer, which knot or regulator
is a source of irritation for most people. Moreover, the elastic loops are sensitive
to wear and loss of elasticity, resulting in the need to, on a regular basis, (re-)adapt
length of the loops in order to retain the face mask in position. Notwithstanding
the need for adaptation of the loops, the most often complaints about face masks retained
with elastic loops is that the elastic loops exert a pressure on the outer ear, especially
at a backside of the outer ear, resulting in irritation of the skin at the contact
points between the elastic loops and a wearer's skin and sometimes in pain at the
outer ear or even headaches.
[0005] Face masks with straps to be tied behind a wearer's head are far more difficult to
apply and remove the face masks with elastic loops and can be painful too when the
wearer's hair gets stuck in the knot. Also the knot can loosen when wearing the face
mask for longer periods such that the face mask does no longer snugly fits on a wearer's
head and hence potentially looses its protection functionality.
[0006] Apart from the above retention types for face masks,
US2281181 discloses a face mask with a retention system comprising ear hooks such as common
in glasses. Such ear hooks can be considered as a kind of non-elastic version of the
elastic loops, and as a face mask, in order to offer optimal protection, preferably
snugly fits on a wearer's head, the ear hooks are tensioned around the outer ear of
a wearer and hence, as is the case with elastic loops, exert a pressure on the outer
ear, especially at a backside of the outer ear, resulting in irritation of the skin
at the contact points between the ear hooks and a wearer's skin and sometimes in pain
at the outer ear or even headaches.
[0007] It is clear from the above that there remains a need for face mask retention system
that is comfortable to wear and easy to put on or take off.
Brief Summary of the Invention
[0008] The present invention concerns a face mask retention system comprising:
- (a) one or more elastic members configured for retaining the face mask on a wearer's
head, said elastic members connected to and transferring a face mask retaining force
to
- (b) earbuds comprising
- (i) a main body configured to be lodged in a concha cavum, behind an intertragical
notch and or tragus of a wearer's outer ear, and
- (ii) an armlike extension with a shoulder defined between the main body and the armlike
extension, said shoulder configured to seat in the intertragical notch of a wearer's
ear and the armlike extension configured to protrude from the ear;
wherein the one or more elastic members are connected to said armlike extension, such
that the face mask retaining force biases the shoulder of the earbuds against the
intertragical notch and/or tragus, which force acts against an upward tilting movement
of the armlike extension typically used to remove the earbuds from a wearer's ear.

Detailed Description
[0010] As illustrated in Fig. 1, a face mask is retained on a wearer's face by a face mask
retention system according to the present invention.
[0011] The face mask is preferably made of a gauze or non-woven fabric and has a predominantly
rectangular or trapezium like outline designed to cover both mouth and nose of a wearer.
The material wherein the face mask is manufactured can be either elastic (=stretching)
or non-elastic. The face mask has two longitudinal side edges, extending predominantly
horizontally when correctly worn by a wearer that is in upright position and two transversal
side edges extending between the longitudinal side edges. The gauze or non-woven fabric
may have a multiple layer build-up and/or can comprise a pocket for receiving a filter
element as is known in the art. Providing a pocket for receiving a filter element
is especially desired for face masks made in an elastic gauze, as when putting the
gauze under tension by stretching the material might result in increased pore sizes
in the gauze. The face mask can be made in transparent material or comprise a transparent
section, in particular to not block sight on a wearer's mouth.
[0012] In a first embodiment, the gauze or non-woven fabric has a predominantly rectangular
outline or with a trapezium like outline wherein the longitudinal side edges extend
substantially parallel and differ slightly in length. The face mask retention system
in this case comprises elastic members connected to on the one hand, the face mask
and on the other hand, earbuds, wherein for the sake of the current invention, the
earbuds are part of the face mask retention system.
[0013] In a most basic execution, four elastic members are provided, each connected to,
on the one hand, a different corner of the face mask and, on the other hand to an
earbud, wherein the elastic members connected to the corners of a same transversal
edge of the face mask are connected to the same earbud, thereby defining a two triangles,
the angles of which are the corners of one transversal side edge and the connection
between the concerned elastic members and the earbuds.
[0014] The earbuds, illustrated in Fig. 2, comprise a main body configured to be lodged
in a concha cavum, behind an intertragical notch and/or tragus of a wearer's outer
ear, and an armlike extension with a shoulder defined between the main body and the
armlike extension, said shoulder configured to seat in the intertragical notch of
a wearer's ear and the armlike extension configured to protrude from the ear. The
earbuds can be either disposable and designed for single or limited use, or made more
rigidly for multiple uses and are preferably made in pressed paper or a plastic material
and have an outer surface, at least in zones where the earbuds are designed to contact
human skin, that either has a very low surface roughness or is cushioned by a layer
of tissue or is made from a highly elastic material.
[0015] According to yet another embodiment, the earbud (Fig 10) comprise means configured
for receiving and fastening the elastic members.
The elastic members can then be pulled alongside and inside the guiding channels of
the earbud and turned around as many times needed to provide for the right tension
and fitting of the mask. Alternatively, no turn arounds are necessary if the user
himself shorten the elastic members prior to attachment by making a knot in the elastic
members. The width and the length of the guiding channels on the earbud and the internal
dimensions of the extended parts may vary depending on the type and thickness of the
elastic members and/or the wearer. The length of the extended parts and/or extended
parts with increased internal dimension can compensate for different sizes of faces.
The elastic members can be fully integrated into the earbud leading to a fashionable
aesthetically acceptable mask retention system. Preferred means are provided in the
center of the main body of the earbuds such as a providing a baffle in an open space
in the middle of the earbud. The advantage of this embodiment is that the earbud can
be used for elastic members already forming part of a commercial mask as well as for
elastic members which are separately sold from the mask such as straps.
[0016] The elastic members are preferably connected to the armlike extension of the earbuds.
In accordance with the present invention, the elastic members are dimensioned such
that, when a wearer puts on the face mask with the earbuds positioned in the concha
cave, a force F
1, shown in Fig. 3, is exerted on the earbuds that extends substantially parallel to
a length direction of the intergratical notch, in other words a force that biases
the shoulder of the earbuds against the intergratical notch, said force thus acting
against an upward tilting movement of the armlike extension of the earbuds, which
upward tilting movement is typically used to remove the earbuds from a wearer's ear.
The forces F
1, applied on both earbuds, results in maintaining forces F
2 on both sides of the face mask, thereby securing the face mask in place on the wearer's
face, as is illustrated in Fig. 8 where the fask mask is securely held on a wearer's
face by the face mask retention system with the earbuds A and B.
[0017] The connection between the earbuds and the elastic members can be permanent or releasable,
eg. by an auxiliary piece that slides over the armlike extension of the earbuds and
is kept in place by a friction fit, or by a magnetic connection, a hook and loop connection
or the like.
[0018] In an alternative execution of the first embodiment, illustrated in Fig. 4a&b, the
aforementioned triangles are defined between the corresponding corners of the lateral
side edges of the face mask and an adaptor piece through which at least one of the
elastic members extend. In this execution, one of the elastic member of each triangle
may be attached to the adaptor piece, whilst the other elastic member extends through
it or both elastic member may extend though the adaptor piece. In case both elastic
members extend through the adaptor piece, both elastic members extend from the adaptor
piece to the earbud onwards, one next to another in a parallel fashion. The adaptor
piece preferably comprises a tubular section through which the one or more elastic
member extend and which is provided with a clamp or friction fits over the elastic
member(s), allowing sliding the adaptor piece along said elastic member(s) and as
such adapting the concerned triangle and as a consequence the direction of the force
exerted on the earbud.
[0019] The elastic members of a first embodiment of the face mask retention system can be
formed by four separate elastic members each connected to a corner of the face mask
by sewing or by extending through a hole provided at a corner of the face mask.
[0020] Alternatively, as shown in Fig. 5, two elastic members can be provided, one extending
along each longitudinal side edge of the face mask such that each elastic member defines
a side edge of the two triangles formed by the face mask retention system. In such
case, the elastic members can extend through a channel formed along each longitudinal
side edge in the face mask or alternatively can be sewn to a longitudinal side edge
of the face mask and create a physical connection between both earbuds.
[0021] Fig. 6a&b illustrate a second embodiment of a face mask retention system that is
particularly suited for face masks having a trapezium outline wherein the parallel
extending longitudinal side edges substantially differ in length. In this case, the
triangle overlaps partially or entirely with the face mask. In the illustrated embodiment
of Fig. 6, four elastic members are provided, one along each (slanting) transversal
side edge of the mask and two elastic members along the top longitudinal side edge,
whereby the elastic members join one another two by two at the top corners of the
face mask and extend from thereon in parallel to the earbuds. Again the triangles
created by the elastic members are configured to exert a force on the earbuds that
extends substantially parallel to a length direction of the intergratical notch, in
other words a force that biases the shoulder of the earbuds against the intergratical
notch and/or tragus, said force thus acting against an upward tilting movement of
the armlike extension of the earbuds, which upward tilting movement is typically used
to remove the earbuds from a wearer's ear.
[0022] In this embodiment, the two elastic members extending along the top longitudinal
side edge can be made as a single elastic member that physically connects both earbuds.
[0023] For all embodiments disclosed supra, the earbuds can comprise integrated speakers
and serve as headphones(/telephone), either wired or wireless with a Bluetooth connection.
[0024] In case the elastic member create a physical connection between both earbuds, as
can be the case in both embodiments described supra, a electric and/or acoustic wire
can be embedded in the elastic member physically connecting both earbuds, and as such
be part of the wiring of the headphones and/or may comprise a battery for powering
the headphones or a microphone connected to the headphones. The electric and/or acoustic
wire can be integrated in the elastic members as an electrically isolated yarn or
a plurality of electrically isolated yarns or as a standard cable wound around the
concerned elastic member as illustrated in Fig. 7. The connection between wiring embedded
or guided along the elastic members and the earbuds can be releasable and is preferably
of an inductive type.
[0025] Alternatively to the embodiment of Fig. 6, the face mask retention system can comprise
one or two top elastic members connected to the face mask at a top side edge and a
single bottom elastic member, connected to a bottom side edge of the face mask and
extending from earbud to earbud. The bottom elastic member is thereby designed to
pass under a wearer's chin when worn. Such embodiment is particularly suited for face
masks made in an elastic material, whereby the bottom elastic member also functions
as a bottom side edge reinforcement for the face mask.
[0026] According to yet another separate embodiment (Fig 4 C/D), the releasable connector
may further comprises means to connect to the elastic members and means to connect
to the earbud.
[0027] According to this embodiment the releasable connector comprise a lower part (Fig
4D) comprising one or more extended parts such as one or more arm like extension(s)
said extended parts configured to protrude from the ear. According to this embodiment,
the arm like extensions comprises means openings/ slot configured for receiving the
elastic members of a mask. According to a further embodiment, the arm like extensions
comprises means for receiving and fastening the elastic members (Fig 4D).
Fig 4D illustrates such an embodiment where the connector comprise two extended parts.
The extended parts form a V-shape thereby optimally guiding the elastomeric members
through this V-pathway. The lower part of this embodiment provides for an adjustable
and fashionable way of wearing a mask. At the top of the lower part, an opening (Fig
4D) is formed at one side of the connector at the point of the two extended parts
connection thereby forming an access starting point for receiving and fastening the
elastic members. The elastic members can then be pulled alongside and inside the guiding
channels of the extended parts and turned around as many times needed to provide for
the right tension and fitting of the mask. Alternatively, no turn arounds are necessary
if the user himself shorten the elastic members prior to attachment by making a knot
in the elastic members. The width and the length of the guiding channels of the extended
parts and the internal dimensions of the extended parts may vary depending on the
type and thickness of the elastic members and/or the wearer. The length of the extended
parts and/or extended parts with increased internal dimension can compensate for different
sizes of faces. The elastic members can be fully integrated into the extended parts
leading to a fashionable aesthetically acceptable mask retention system. Preferred
extended parts are in the form of a tube, being hollow with a baffle in the center
of the tube (Fig 4D)

[0029] The present invention is also directed to a face mask comprises two guides, one along
each transversal side edge, each guide defined by a pair of slits provided in the
gauze or non-woven fabric of the mask and configured to receive an elastic loop therethrough.
[0030] Fig. 9 shows such an embodiment of the present invention, comprising a face mask
preferably made of a gauze or non-woven fabric and having a predominantly rectangular
or trapezium like outline designed to cover both mouth and nose of a wearer. The material
wherein the face mask is manufactured can be either elastic (=stretching) or non-elastic.
The face mask has two longitudinal side edges, extending predominantly horizontal
when correctly worn by a wearer that is in upright position and two transversal side
edges extending between the longitudinal side edges. The gauze or non-woven fabric
may have a multiple layer build-up and/or can comprise a pocket for receiving a filter
element as is known in the art. The face mask can be made in transparent material
or comprise a transparent section, in particular not to block sight on a wearer's
mouth.
[0031] According to this embodiment, the face mask comprises two guides, one along each
transversal side edge, each guide defined by a pair of slits provided in the gauze
or non-woven fabric of the mask and configured to receive an elastic loop therethrough.
The elastic loops hereby correspond to two elastic members as defined supra in accordance
with embodiments Fig 4C, whereby the elastic members are connectable to one another
two by two to provide said two elastic loops.
[0032] The above mentioned slits of each guide in the face mask are preferably positioned
in a spaced apart setting, one proximate to each longitudinal side edge, whereby each
elastic loop extends through one guide to obtain the aforementioned triangle when
connected to an earbud. The face mask of the present invention is firmly hold close
to the face due to the loops which holds down the side edges of the mask to the face.
The elastic loops are hereby configured such that they can be opened to remove the
loops from the guide as in a kit of parts, such that one pair of elastic loops can
consecutively be used in combination with a multitude of face masks according to the
present invention.
[0033] In case the face mask comprises only a single layer of material, the loops preferably
extend through the guide such that the part of the loops situated between both slits
of each guide, faces a wearer's face (=extends at a backside of the mask) and the
remainder of the loops emerges to a front side of the mask, i.e. the visible side
of the mask when correctly worn by a wearer, at the slits, from where the elastic
members extend to the earbuds.
[0034] In case of a multiple layer build-up, the guide preferably extends between two consecutive
layers of the mask, with the slits only extending through a outermost front layer,
i.e. at the visible side of the mask when correctly worn by a wearer. In analogy with
a single layer build-up of the mask, the part of the loops situated between both slits
of each guide, extends between two consecutive layers of the mask and the remainder
of the loops emerges to a front side of the mask, i.e. the visible side of the mask
when correctly worn by a wearer, at the slits, from where the elastic members extend
to the earbuds.
[0035] Depending on the material wherein the face mask is manufactured, it is ideal to reinforce
the guides in the mask, either by adding reinforcement elements such as metal insert
at the transversal edge of the mask or by a reinforced stich line or by providing
a tube between both slits of each guide, this to prevent unwanted deformation of the
mask when the loops are under tension and ensure a good and comfortable fit of the
face to a wearer's face.
