Description

The present invention relates to an auxiliary spacer for a mask used when wearing a mask for hygiene or the like using a flexible and breathable mask sheet.

The epidemic of the new coronavirus will not end even in the summer of 2020, and many people wear sanitary masks even in the hot and humid summer as a countermeasure against the epidemic of the new coronavirus from the viewpoint of mainly preventing droplet infection. Is going.
The death toll of this new coronavirus in Japan has exceeded 1,000 as of the end of July 2020.
On the other hand, heat stroke, which increases at high temperatures, has never fallen below 500 in terms of annual deaths from 2010 to 2018. In particular, in both 2010 and 2018, more than 1,500 people died from heat stroke, which is about 1.5 times the number of deaths caused by the above-mentioned new coronavirus.
As is clear from such a comparison of the number of deaths, it can be said that countermeasures against the new coronavirus and heat stroke are of great importance.

However, the hygiene mask is highly airtight due to its original function, and the wearer's own exhaled breath stays between the mask sheet and the face, so that hot air stays inside the mask and it feels hot when wearing the mask. Cannot be avoided. Therefore, it must be said that wearing a hygiene mask in the summer increases the risk of heat stroke, but there are still effective and practical means to solve these two difficult problems. The current situation is not shown.

Looking at the prior art documents, Patent Document 1 has an object of providing a hygienic mask having hygienic functions such as dustproof and pollenproof, and also having measures against heat stroke. The present invention discloses an invention relating to a cool mask, which is equipped with a pocket for storing hygiene, and also has a so-called heat stroke countermeasure that lowers the body temperature by putting a cooled or frozen ice pack in the pocket to cool the cheeks. However, it is necessary to prepare a cooled or frozen ice pack, and there remains a problem in that it can be easily and continuously used.
Patent Document 2 can be used without impairing the function of the mask, using a commercially available mask that covers both the mouth and nose as it is, without worrying about makeup removal or wearing marks, and breathing. It discloses an auxiliary spacer intervening between the mask sheet and the face for the purpose of facilitating conversation. However, this auxiliary spacer has an annular shape that covers the circumference of the user's nose and mouth, and the entire auxiliary spacer is attached so as to be completely contained inside the mask sheet. Therefore, it is not possible to prevent the wearer's own exhaled breath from staying between the mask sheet and the face.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(overview)
The mask auxiliary spacer according to the first embodiment shown in FIGS. 1 to 3 is arranged between a hygienic mask provided with mask sheets s having flexibility and breathability and a user's face f. It is provided with an intervening portion 10.
The intervening portion 10 includes an upper face facing portion 11 and a lower extending portion 31.
Since it is generally desirable that the mask does not form a gap between the periphery of the mask sheet s and the face f of the user, the exhaled breath a of the user is shown in FIG. 1 (B). As described above, the exhaled air a tends to stay between the mask sheet s and the face f, and the hot air of the exhaled air a stays around the nose and mouth at high temperatures such as summer, regardless of cold weather, which causes the temperature of the face f to rise. I will be there.
On the other hand, when the auxiliary spacer for mask is used, as shown in FIG. 1 (A), the end portion u of the mask sheet of the mask sheet s is on the outer surface of the extending portion 31 of the auxiliary spacer for mask. Since the mask is worn in contact with each other, the exhaust space e is secured downward between the intervening portion 10 and the user's face f and chin c. As a result, the exhaled air a of the user can be released substantially downward from the exhaust space e to the outside, and the temperature rise of the face f of the user can be suppressed.
Commercially available masks can be appropriately selected and used, and the mask sheets s can be made of non-woven fabric, woven or knitted fabric, urethane foam, etc., and can suppress the invasion of droplets and pollen. Those having micropores capable of ensuring respiration and having appropriate flexibility can be appropriately selected and used.
In the following description, as a general rule, the side closer to the user's face f will be referred to as the rear, and the side away from the user's face f will be described as the front. Further, the auxiliary spacer for the mask discharges the exhaled breath a of the user from the inside to the outside of the mask sheet, and the direction substantially orthogonal to the flow direction thereof will be described as the left-right direction. Further, the upstream side (the side far from the exhaust space e) in the flow direction will be described as the upward direction, and the downstream side (the side closer to the exhaust space e) will be described as the downward direction.

(About the face facing portion 11)
The intervening portion 10 of the auxiliary spacer for the mask according to this embodiment has rigidity to the extent that it does not cause a large deformation when inserted between the mask sheet s and the face f of the user, and is a synthetic resin. It can be composed of a molded product of.
As shown in FIG. 2, the face facing portion 11 includes left and right face contact portions 12 and a spacer portion 13 passed between the two face contact portions 12.

(About the face contact part 12)
The face contact portion 12 has a plate shape extending in the vertical direction in the figure, and by making surface contact with the left and right face f of the user's mouth, the stress concentration is suppressed and the wearing feeling is suppressed. Suppresses the decrease in. It is also preferable that the contact surface of the face contact portion 12 is made of an elastic member made of silicon or the like in order to enhance the wearing feeling.

(About the spacer part 13)
The spacer portion 13 is provided with a breathing opening 24 for ensuring a space between the face f around the mouth and the mask sheet s and allowing the outside air from the mask sheet s to pass through the nose and mouth. Various shapes and forms can be adopted, but in this embodiment, it is carried out assuming that it has the following configuration.
The spacer portion 13 according to this embodiment includes an upper frame 14 connected and supported on the upper part of the face contact portion 12, and a lower frame 17 connected and supported on the lower part of the face contact portion 12.
The upper frame 14 includes left and right side portions 15 extending forward from the upper part of the face contact portion 12, and a front portion 16 passed between the left and right side portions 15. The lower frame 17 includes left and right side portions 18 extending forward from the lower part of the face contact portion 12, and a front portion 19 passed between the left and right side portions 18. In this embodiment, since the side portion 18 of the lower frame 17 is longer than the side portion 15 of the upper frame 14, the lower frame 17 protrudes forward from the upper frame 14 in a plan view.
The left and right center frames 20 are passed in the substantially vertical direction between the upper frame 14 and the lower frame 17. The central frame 20 includes an upper portion 21 extending forward from the front portion 16 of the upper frame 14, and a vertical portion 22 connecting the front end of the upper portion 21 and the front portion 19 of the lower frame 17.
Further, the left and right central frames 20 include a front bar portion 23 passed between the left and right vertical portions 22, thereby reliably suppressing the mask from approaching the face and creating a space. At the same time, the overall strength can be increased.
As described above, there is nothing between the respective parts of the spacer part 13, and the breathing opening 24 is sufficiently open so that the person can breathe comfortably.
As described above, since the spacer portion 13 of the auxiliary spacer for the mask is configured by combining a thin rod-shaped frame, the breathing opening 24 is a large opening, but the structure of the frame is changed in various ways. Alternatively, the spacer portion 13 may be configured with a large number of relatively small openings such as a punching sheet and a relatively coarse mesh.

(About the extension 31)
An extending portion 31 is arranged below the face facing portion 11. The extension portion 31 is preferably extended below the user's chin c to prevent the end portion u of the mask sheet from coming into close contact with the user's face f or chin c, and is extended. An exhaust space e is formed between the portion 31 and the face f including the user's chin c.
Specifically, the extension portion 31 includes a front portion 32 extending downward from the front portion 19 of the lower frame 17 described above, and left and right side portions 33 extending downward from the left and right side portions 18 of the lower frame 17. It is. The extending portion 31 may be provided with only the front portion 32, but the deformation of the front portion 32 can be suppressed by including the side portion 33. In particular, some of the end u of the mask sheet have rubber passed through them, and there is a risk that the front portion 32 will be deformed so as to approach the face due to the tension of the rubber, etc., but the left and right side portions 33 are provided. As a result, deformation of the front portion 32 can be suppressed. In this embodiment, the extension portion 31 is formed as a plate without an opening, but it may be implemented as having an opening by being formed of a thin rod-shaped frame or the like like the spacer portion 13. I do not care.

(how to use)
The mask auxiliary spacer according to this embodiment is held by elasticity such as a rubber string of the mask in a state of being sandwiched between the user's face f and the mask sheet s. In this wearing state, the face contact portion 12 is in contact with the face f on both sides of the user's mouth, and almost the entire intervening portion 10 of the mask auxiliary spacer is covered with the mask sheet s, and the lower end of the extending portion 31 is formed. Only the vicinity is slightly protruding from the end u of the mask sheet. In order to position the end portion u of the mask sheet, a locking portion (not shown) such as an unevenness or a slit may be provided near the lower end of the extending portion 31.
By attaching this mask auxiliary spacer, a sufficient space can be created between the area around the user's nostrils and mouth and the mask sheet s.
More specifically, the upper frame 14 and the central frame 20 of the spacer portion 13 bulge forward to suppress the adhesion of the mask sheet s to the face f, and the space created therein is discharged from the nose a. It becomes a space for smooth discharge. Further, since a sufficient opening area is secured by the breathing opening 24 of the spacer portion 13, it is possible to smoothly perform breathing through the mask sheet s.

Further, the extending portion 31 always secures an exhaust space e that opens downward beyond the end portion u of the mask sheet between the face f including the user's chin c, so that the space e is smooth downward. Exhaust of exhaled breath and exhaust heat can be realized.
As a result, fresh air can be taken into the inside of the mask sheet s from the mask sheet s and the breathing opening 24, the temperature of the face can be lowered, and measures against heat stroke can be taken. Further, since the exhaust space e is opened downward from the end portion u of the mask sheet, it is possible to suppress the exhalation a of the user from flowing forward. Further, by forming the extending portion 31 into a plate shape, the effect of preventing the diffusion of droplets can be enhanced.

(Second embodiment)
