Description

The invention according to the present application (hereinafter, "the present invention") relates to a string binding type mask in which the mask body is fixed and worn by string binding in the vicinity of the back of the head and the vicinity of the back of the neck.

Recently, as a preventive measure against the infection of the new coronavirus that is prevalent worldwide, most people, indoors and outdoors, wear masks on a daily basis.

However, when wearing a mask as a preventive measure against infection, it is preferable that the outer peripheral edge of the mask body is evenly adhered to the face, with an emphasis on preventing the spread of the virus from the wearer. Most of these masks are ear-hook type, and rubber (hereinafter, abbreviated as "ear rubber") is used as a means for holding and fixing the mask to the wearer's face. For this reason, it is desirable to use rubber with strong tensile force in order to improve the adhesion of the mask body to the face, but when rubber with strong tensile force is used, it often bites into the ears and causes pain. .. On the other hand, if rubber having a weak tensile force is used to relieve this pain, there is a problem that the adhesion of the mask body to the face is lowered.

Therefore, in order to reduce the burden on the ear, a mask provided with an adjusting portion for adjusting the length and strength of the rubber in the middle of the ear rubber (see, for example, Patent Document 1) and the ear rubber are elastic. A mask to which a member is attached (see, for example, Patent Document 2) is disclosed.

However, the masks described in any of these patent documents are supposed to use a single rubber cord as the ear rubber, and the tensile force acts concentrated in the length direction of the ear rubber, so that the rubber is made of rubber. All the tensile forces acted in the direction of expansion and contraction of the ear rubber, that is, in the same direction as the tightening direction by the ear hook, which caused pain in the ears and was insufficient to eliminate the tightening by the ear rubber.

As a mask with a different configuration, in order to avoid the burden on the ear hook, a connector for connecting the left and right ear rubbers at the back of the head and the back of the neck and a device for adjusting the length of the ear hook were attached. Is disclosed (see, for example, Patent Document 3 and Patent Document 4).

Japanese Unexamined Patent Publication No. 2014-210153 Japanese Unexamined Patent Publication No. 2015-042231 International Publication WO2016 / 047579 Gazette Utility Model Registration No. 3229291

However, in the published inventions and registered inventions of the above examples, elastic members such as rubber cords are used as ear hooks and occipital fixing means, and it is necessary to have a certain strong tensile force in order to improve the adhesion. When used for a long time in such a state, in addition to suffocation, the movement of the mouth during conversation may cause skin problems such as rough skin and rash (irritant contact dermatitis) due to the frictional stimulation of the crimped string. There was a risk of inviting.

The present invention is intended to solve the above problems, and can be fitted to the wearer's face in a good and airtight manner without burdening the ears, and can easily follow the movement of the mouth with a string. Provided is a mask intended to eliminate frictional irritation.

In order to solve the above problems, the present invention specified as claim 1 is separated vertically from each other as a pair on the left and right sides of the mask body that covers at least from the nose tip to the tip of the jaw of the wearer and the vicinity of the left and right edges of the mask body. It is a string binding type mask that consists of two sets of attached strings and each set of strings is not linked to each other and is bound and fixed near the back of the head and the back of the nose, respectively. Is formed of a non-stretchable member, and is attached to the mask body via a stretchable member arranged at a mounting portion with the mask body.

The present invention according to claim 2 is characterized in that the elastic member is a string-shaped, a planar shape, a strip-shaped, a coil-shaped, or a combination thereof.

According to the third aspect of the present invention, in the invention of claim 1 or 2, the expansion / contraction rate of the expansion / contraction member and the expansion / contraction rate of the expansion / contraction member and the expansion / contraction rate of the expansion / contraction member are obtained in the attachment of the mask body of two pairs of left and right strings attached vertically and separately. It is characterized in that the length or one of them is made different by the upper and lower strings.

Further, the above-mentioned string binding means is either a string tying method performed near the back of the head and the back of the neck (rear side of the neck), or a friction fixing method using a cord stopper that slides both strings extending from the left and right together. Can also be selected.

Since the mask according to the present invention (hereinafter referred to as “the present mask”) is configured as described above, it can be fitted well to the wearer's face without causing pain in the ears. In particular, since it is attached to the mask body by interposing an independent elastic member for each string body, it has an effect of easily following the movement of the mouth and jaw. This can reduce the rubbing of the string and eliminate the frictional irritation to the skin.

In addition, since this mask is a string binding type, it is a non-stretchable string that does not stretch when worn, and the optimum binding is artificially performed according to the wearer's preference, so the burden on the back of the head and the back of the neck is selected. Can be mitigated.

Furthermore, with a normal rubber ear-hook type mask, pulling the mask forward when eating or eating often causes it to come off the ear-hook, but with this mask, the expansion of the elastic member can be used. Therefore, it also has the effect of not having to wear it again.

It is a perspective view which shows the state which wore the mask which concerns on embodiment of this invention (hereinafter, abbreviated as "this Example"). It is a front view plan view which shows the mask which concerns on this Example, and since the string body has a long shape, a part length is omitted. It is a top view of the front view of the mask to which another embodiment of the string binding means is applied. It is explanatory drawing which showed the tensile force acting on the mask main body of this Example.

[Description of configuration]
Hereinafter, the mask according to this embodiment will be described with reference to the drawings. However, the technical scope of the present invention is not construed as being limited to the illustrated examples, and is determined based on the description of the scope of claims, and the form thereof is within a range easily understood by those skilled in the art. And it is possible to change the specifications as appropriate.
For convenience of explanation, the front side of the face of the mask wearer is set as the front, and based on this, the front / rear, the left-right direction, and the up-down direction are defined and used for the explanation.

The mask according to the present embodiment indicated by reference numeral 1 is a mask main body 11 that covers the nose, mouth, chin, etc. of the wearer's face in a series, and a pair of left and right strings near the left and right edges of the mask main body 11. It is provided with two sets of string bodies 12 to which the body 12 is attached at a distance from the top and bottom. Each string body 12 is formed of a narrow band member which is a non-stretchable member that does not expand or contract, and can be attached to the mask body 11 with an elastic elastic member 13 (for example, a rubber fiber) arranged at the attachment portion. Material, coiled fiber material, etc.).

The length of the telescopic member 13 is appropriate, but in this embodiment, it is set to a length of about 2 to 3 cm. In this length selection, the pair of left and right may be set to different lengths at the top and bottom, or the expansion / contraction ratio (adjustment of tensile force) may be different even if the length is the same. Further, the expansion / contraction force and the length may be set differently.

In this embodiment, the expansion / contraction member 13 is attached to the mask body 11 by an ultrasonic welding method, but the method is not limited to this, and a heat welding method, a hot melt adhesive, or a UV curable adhesive can be used. It may be attached by using or the like.

As shown in FIG. 1, each string body 12 having the above configuration has a knot 14 (for example, a bow knot) and a knot 14 (for example, a bow knot) on the tip end side of the pair of left and right string bodies 12pu on the upper side near the back of the head (or near the crown) of the wearer. A pair of left and right string bodies 12pd on the lower side are fixed by providing a knot 14 near the back of the neck (rear side of the neck). The position of these knots 14 is not limited to the above-mentioned position, and may be provided in the vicinity of the head side portion or the vicinity of the neck peripheral portion depending on the situation.

Further, in the mask 1 of the present embodiment, it is fixed with a string knot as described above, but the present invention is not limited to this, and as shown in FIG. 3, a pair of string bodies 12p extending from the left and right slide together. It may be fixed so as to be bound by friction fixing by the cord stopper 15.

The mask body 11 of this embodiment uses a mask of N95 standard of NIOSH (National Institute for Occupational Safety and Health) standard, which indicates the capture rate of a predetermined particulate matter and is used after wearing. Adhesion between the mask and the face is not guaranteed. Therefore, the mask 1 of the present embodiment is formed in a cup shape protruding in front of the face as shown in order to enhance the adhesion of the mask body 11 to the face, and the left and right edges 11s are outside the nasolabial fold of the face. It covers the face up to the position where it comes into contact with the cheek surface. Since it is cup-shaped, a certain ventilation gap is provided on the inner surface side (face side) of the mask body 11 so as not to come into direct contact with the wearer's nose tip and lips.

[Action and effect of Examples]
In this state, in the plan view (FIG. 4) of the side view of the mask body 11 when worn, the direction in front of the face (arrow A) and the upward diagonal direction of the pair of strings attached vertically separated from each other (arrow A). (Arrow B) and the tensile force in the downward diagonal direction (arrow C) are in a balanced state, and a stable close contact state can be maintained.

In addition, each of the elastic members 13 can individually expand and contract to stably maintain the movement of the mask body 11 and its edge 11s caused by the vertical movement of the jaw and the swelling of the cheeks due to conversation and breathing.

Furthermore, when ventilating the mouth, the mask body 11 can be moved forward or diagonally upward within the range of the expansion / contraction amount of the expansion / contraction member 13, which is a new mask that enables flexible response. Can be provided.
