본 발명은 접철식 마스크 및 그 제조방법에 관한 것으로서, 보다 상세하게는 접철 구조에 의해 구조적 강성이 향상되고, 사용 여부를 시각적으로 확인할 수 있는 접철식 마스크 및 그 제조방법에 관한 것이다.The present invention relates to a foldable mask and a method for manufacturing the same, and more particularly, to a foldable mask with improved structural rigidity by a foldable structure and visually confirming whether to use it, and a method for manufacturing the same.

일반적으로 호흡기 보호효과를 위한 안면 마스크로는 성형 컵 형상과 납작하게 접히는 형상 등이 있다. 납작하게 접히는 형태는, 다수 면이 접히는 방향에 따라 다시 수평 적첩식과 수직 적첩식으로 나누어질 수 있다. In general, as a face mask for respiratory protection, there are a molded cup shape and a flat folding shape. The flat folding form may be divided into a horizontal stacking type and a vertical stacking type again according to the direction in which multiple surfaces are folded.

그러나, 종래의 성형 컵 형상의 마스크는 단단한 구조에 의하여 바깥으로부터 밀폐되는 내부 공기 체임버를 정확하게 구축할 수 있을 것 같지만 사람마다 얼굴 윤곽이 달라 이를 다 수용하기가 어렵다. 또한, 컵의 외주연의 폭이 제한되어 턱 관절과 관자놀이 사이에 위치하게 되어 말을 하는 것과 같은 얼굴 근육 움직임에 밀폐 구조를 유지하기가 어렵다. However, the conventional molded cup-shaped mask seems to be able to accurately build an internal air chamber sealed from the outside by a rigid structure, but it is difficult to accommodate them all because the facial contours of each person are different. In addition, since the width of the outer periphery of the cup is limited, it is located between the temporomandibular joint and the temple, so that it is difficult to maintain a closed structure for facial muscle movements such as speaking.

또한, 마스크가 사용자의 호흡에 의해 형태가 변경되며, 마스크의 변형에 의해 마스크가 피부에 밀착됨에 따라 호흡이 어려울 수 있다. 또한, 마스크의 내측면에 화장이 묻거나 얼굴의 화장이 마스크에 의해 지워질 수 있다.In addition, the shape of the mask is changed by the user's breathing, and as the mask is in close contact with the skin due to the deformation of the mask, breathing may be difficult. Also, makeup may be applied to the inner surface of the mask, or makeup on the face may be removed by the mask.

상부외곽라인(135)과 하부외곽라인(145)을 절단하여 상부사이드접철부(130)와 하부사이드부(140)를 형성한다. 커버부가 상부외곽라인(135)과 하부외곽라인(145)의 폭방향 중심부를 절단한다. 때, 상부외곽라인(135)과 하부외곽라인(145)은 동시에 절단하거나 순차적으로 절단할 수 있다. 상부외곽라인(135)과 하부외곽라인(145)이 절단되더라도 상부사이드접철부(130)와 하부사이드부(140)의 외측 둘레부는 접합된 상태를 그대로 유지한다.The upper outer line 135 and the lower outer line 145 are cut to form the upper side folding part 130 and the lower side part 140 . The cover part cuts the widthwise center of the upper outer line 135 and the lower outer line 145 . At this time, the upper outer line 135 and the lower outer line 145 may be cut simultaneously or sequentially. Even if the upper outer line 135 and the lower outer line 145 are cut, the outer periphery of the upper side folding part 130 and the lower side part 140 maintains the joined state as it is.

상부사이드접철부(130)와 하부사이드부(140)의 양측에 귀걸이부(160)를 각각 연결한다. 귀걸이부(160)의 양측은 초음파 융착에 의해 상부사이드접철부(130)와 하부사이드부(140)의 양측에 고정된다.Earrings 160 are respectively connected to both sides of the upper side folding part 130 and the lower side part 140 .
