Definitions
- the present invention relates to a mask used for health care, food hygiene, pollen measures, infection prevention measures and hygiene in daily life, and a mask used for general industrial use, particularly the adhesion of the nose which is difficult to closely contact the wearer's face Related to masks that have
- Masks are mainly used in places where hygiene is required, such as food factories and precision machine factories, in health care or daily life, and in industrial environments where there are many floating dusts.
- the present invention is used in these fields, and the mask body is composed of sheet-like filters such as gauze and non-woven fabric, which covers the nose, mouth and chin area of the human face, Although it is worn, since the shape of the human face is various, in order to match the shape of the face conventionally, various devices are applied. In particular, it is difficult to follow the contours of the nose and a reliable fit can not be obtained.
- Patent Document 1 discloses a sheet-like filter with metal parts such as soft aluminum laminated, and in particular, a sharp relief around the nose, a mask that bends the metal parts to conform to the shape of each individual's nose ing.
- each individual must bend according to his / her own face shape (nose shape), and it is difficult to easily match even if it is bent. It doesn't fit well with bending, nor does it fit with bending too much.
- this mask is used for relatively inexpensive masks such as disposable dust masks and other simple masks, since it uses metal, it is necessary to separate metal parts at the time of disposal. There is a problem of being bothersome.
- urethane foam and other low-cost sponges are breathable, so dust and the like pass from the cross section of the sponge and there is a high possibility of penetration into the mask, and high-humidity breath passes through the sponge and the glasses become cloudy There are also negative effects. Also, non-ventilated self-supporting foam materials are expensive.
- pattern 3 which folds the vicinity of the nose of the filter to the side in close contact with the face to improve the adhesion
- pattern 4 and 5 a method of bonding another filter to the back side of the mask. And repulsive force to secure sufficient adhesion can not be obtained.
- the present invention is an improvement of the above-mentioned drawbacks, and an object of the present invention is to provide a mask having a structure capable of obtaining cushioning properties and high protection performance by following the contour of the nose and enhancing adhesion.
- the gist of the present invention is a mask comprising a filter for filtering dust and a binding cord for attachment, the upper edge of the filter is folded back to provide a flap, and a sponge body is attached to the inside of the nose to form a nose It is a mask characterized in that it is in close contact with the concave portions on both sides.
- the filter flaps are provided along the recesses on both sides of the nose, and the sponge is attached to the inside of the filter flaps to provide cushioning properties and improve adhesion with the nose. be able to.
- FIG. 1 is a front view of the back surface of a mask according to the present invention.
- FIG. 2 is a plan view of the mask as viewed from above.
- FIG. 3 is a cross-sectional view of the flap portion of the mask.
- FIG. 4 is a view of using the mask according to the present invention.
- the present invention will be described in detail.
- the mask according to the present invention may be either a hygiene mask or a dustproof mask, and the filter constituting the mask is not particularly limited to non-woven fabric, gauze or the like.
- a sponge body to be used any material such as rubber sponge and urethane foam may be used.
- the sponge body may be either an independent foam or a continuous foam, but since the mask according to the present invention is not at a site communicating with the open air, it is possible to select an inexpensive sponge that is breathable.
- the shape of the mask is also not particularly limited, as long as the mask main body covering the nose, the mouth and the vicinity of the chin and the fastening straps are provided on both side edges of the mask main body. Application to the mask according to Japanese Patent Application No.
- the mask according to the present invention is provided with a flap on the back surface at a location corresponding to the recess of the nose, and a sponge such as urethane foam is inserted inside the flap, and the repulsion is achieved by inserting the sponge body.
- the figure is a front view of the back of the mask according to the present invention, this mask being symmetrical with respect to the center lines O, O and having a rectangular filter 1, 1 'at the center and a triangular shape at the top of the rectangle
- the filters 2, 2 ' are integrally provided with the triangular filters 3, 3' at the lower part to constitute a mask body.
- the two edges of the mask body are folded back with a tightening cord.
- the mask 4, 4 'hardened by ultrasonic welding or the like on the upper triangular filter so as to retain a three-dimensional shape and be easily folded, is similarly hardened by ultrasonic welding or the like on the lower triangular filter as well. Set up the 5 and 5 '.
- the vicinity of the nose of such a mask is folded back to the side in close contact with the face to provide the flaps 6, 6 ', and the sponge bodies 7, 7' are interposed inside the folded flaps 6, 6 '.
- the portion to which the sponge is attached may be folded back and the left and right sides of the sponge may be bonded by ultrasonic welding or the like, or the sponge may be attached to the folded end surface.
- the mask according to the present invention is provided with flaps along the recesses on both sides of the nose so as to follow the relief of the nose, and a sponge such as urethane foam is affixed to the inside, so the adhesion between the face and the mask Can provide a good mask.
Abstract
Description
本発明はこれらの分野で使用されるもので、マスク本体はガーゼ、不織布などのシート状フィルターで構成され、これで人間の顔の鼻、口部及びあご付近を覆い、しめひもを頭部にかけて装着するが、人間の顔の形状は様々であるので、従来から顔の形状に合わせるため、いろいろな工夫が施されている。
特に、鼻部の起伏に追従することが難しく、確実なフィットが得られない。この改良方法として特許文献1にはシート状フィルターに軟質アルミニウムなどの金属部品を貼り合わせ、特に起伏のはげしい鼻部周辺は、金属部品を曲げて各個人の鼻部の形状に合わせるマスクが記載されている。しかし、この場合各個人で自己の顔型(鼻部形状)に合わせて曲げなければならず、曲げても容易には合わせ難い。曲げが甘いと合わなく、曲げすぎても合わない。更に、このマスクは使い捨て式防じんマスク及びその他の簡易マスク等の比較的安価なマスクに使用されているが、金属を使用しているため、廃棄の際、金属部品を分別しなければならず、煩わしいという問題がある。
近年では、軟質アルミニウムなどの金属製に替わる素材としてポリオレフィン系合成樹脂からなる形状保持機能を備えた可撓性の形状保持材料を使用したものもあるが(特許文献2)、高価な材料であることと、時間と共に押さえつけがゆるむといった問題がある。
また、鼻部の密着性を高めるため、上記部品の押さえつけを強くすると鼻に痛みが生じることがある。その場合、上記部品と併せて鼻に当たる箇所にウレタンフォームなどのスポンジを貼り、鼻部のクッション性と密着性を向上させることも行われている。しかし、ウレタンフォームなどのスポンジで安価なものは通気性があるためスポンジの断面から粉じんなどが通過し、マスク内に侵入する可能性が高く、湿度の高い呼気がスポンジを通過してメガネが曇るなどの弊害もある。また、通気性のない独立発泡素材は高価である。
また、フィルターの鼻部付近を顔面と密着する側に折り返して、密着性を向上させる方法(特許文献3)、マスクの裏側に別のフィルターを貼り合わせる方法(特許文献4・5)もあるが、十分な密着性を確保する反発力を得ることができない。
図2は該マスクを上部より見た平面図である。
図3は該マスクのフラップ部分の断面図である。
図4は本発明に係るマスクを装着した使用図である。
本発明に係るマスクは、衛生用マスク或いは防塵用マスクの何れでもよく、またマスクを構成するフィルターとしては不織布、ガーゼなどで特に限定はされない。また、使用されるスポンジ体としては、ラバースポンジ、ウレタンフォーム等何れの材質でも良い。そして、スポンジ体としては独立発泡、または連続発泡の何れでもよいが、本発明に係るマスクは外気と通じる部位にないため、通気性のある安価なスポンジを選択することが可能である。
マスクの形状についても特に限定はなく、鼻部、口部、及び顎付近を覆うマスク本体と、該マスク本体の両側縁にしめひもを設けたものであればよいが、特にマスク本体としては本出願人が先に出願した特願2009−059307に係るマスクに適用すると、小さく折り畳める顔面に密着した使い捨てマスクを提供することができるので好ましい。
前記特願2009−059307に係るマスクとは、マスク本体の中心線を顔面の鼻梁の線に合わせ、左右に展開した長方形の中央部のフィルターとその長辺の上下に三角形状のフィルターとが一体に構成されたものである。従って、本発明にかかるマスクはその裏面に鼻部の凹部に相当する個所にフラップを設け、該フラップの内側にウレタンフォームなどのスポンジを入れたもので、該スポンジ体を入れることによって反発力が生まれ、鼻部に適度な圧力が加わり、高い密着性を確保することが可能となると共に、スポンジ体の緩衝性によって痛みを感じることはない。また、粉じんを捕集するフィルターでスポンジ体を覆っているため、スポンジ体の断面方向からの漏れ込みもない。
次に実施例として図面をもって具体的に説明するが、本発明はこの実施例によって限定させるものではない。
本発明においては折り返したフラップの内側にスポンジを入れることによって反発力が生じ、鼻部に適度な圧力が加わり、高い密着性を確保することが可能となり、また、粉じんを捕集するフィルターでスポンジ体を覆っているため、スポンジ体の断面方向からの漏れ込みもない。
