口罩Mask

本創作係與口罩有關,特別是有關於一種防止口沫噴灑之口罩。This creation is related to masks, especially one that prevents the spray of foam.

按,一般市面上所販售之口罩,係以棉質的口罩遮蓋住配戴者的口鼻,另外再透過彈性帶體掛於配戴者耳部而防止配戴者口沫噴灑,以免病毒或細菌經由口沫傳染,但由於此類口罩配戴時係將配戴者之口鼻完全包覆住,因此如長期配戴下配戴者會產生不舒適感甚至會影響到呼吸之順暢,另外此類口罩亦會影響到配戴者談話之清晰度,因此如餐飲業者則非常不適合配戴此類口罩。為此,市面上便出現一種不會將口鼻完全覆蓋之口罩,TWM438915所揭露之口罩即屬此類。According to the general masks sold on the market, the mouth and nose of the wearer are covered with a cotton mask, and the elastic band is hung on the ear of the wearer to prevent the wearer from spraying the spray to avoid the virus. Or the bacteria are transmitted through the mouth foam, but because the mask is completely covered by the wearer's mouth and nose, if the wearer wears it for a long time, it will cause discomfort and even affect the smoothness of the breath. In addition, such masks also affect the clarity of the wearer's conversation, so it is very unsuitable for the food and beverage industry to wear such masks. To this end, there is a mask on the market that does not completely cover the mouth and nose. The mask disclosed in TWM438915 belongs to this category.

然而,此類習知口罩係由一擋片及一架體所組成,雖然具有不會將口鼻完全覆蓋之功能,但此類習知於製造時需額外分開製造該擋片及該架體,因此會增加製造成本,另外該擋片與該架體係為組接方式,故配戴者於作業時配戴則容易發生該擋片與該架體相互脫離之問題,而影響到配戴者之工作效率及品質,存在亟待改善之缺弊。However, such conventional masks are composed of a flap and a body, and although they have a function of not completely covering the nose and mouth, such conventionally required to separately manufacture the flap and the frame during manufacture. Therefore, the manufacturing cost is increased. In addition, the baffle is assembled with the frame system, so that the wearer is prone to the problem that the baffle and the frame are separated from each other when the wearer wears the work, thereby affecting the wearer. The work efficiency and quality have shortcomings that need to be improved.

因此,有必要提供一種新穎且具有進步性之口罩,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive mask to solve the above problems.

本創作之主要目的在於提供一種口罩,可有效防止配戴者之口沫噴灑,且該口罩不會將口鼻完全覆蓋,故不會影響到呼吸之順暢且不會影響到配戴者談話時之清晰度,可使配戴者配戴時可感覺較舒適,另外,該口罩係為一體成型製成,因此製造上容易且可大幅降低製造之成本。The main purpose of this creation is to provide a mask that can effectively prevent the wearer from spraying the mouth spray, and the mask does not completely cover the mouth and nose, so it does not affect the smoothness of breathing and does not affect the wearer's conversation.
