  • Publication number: 20190174845
    Abstract: A face mask having an embedded nose pad, including: a mask body having an outer layer, a middle layer, and an inner layer sequentially; and a nose pad disposed on the outer layer, wherein the inner layer extends and doubles back to form an inner layer flap, and the nose pad is enclosed by the inner layer flap and the outer layer jointly, allowing a raised portion to be formed on the mask body and corresponding in position to the nose pad. Hence, the face mask effectively prevents users from inhaling unfiltered air and stops exhaled moisture from rising through the mask body, thereby not only precluding a leak through the nasal portion of the face mask but also preventing eyeglasses from fogging.

  • Patent number: 8052821
    Abstract: A method for manufacturing facemask structure includes following steps. A facemask with first folds is placed on a seat and a pressing body forces the facemask so as to form step-shaped structures. Then, two movable plates are used to form the step-shaped structures as second folds on the facemask. Thereby, the mask can be stretched both vertically and horizontally, in a way that the mask body becomes more three-dimensional, fitting more firmly to the contours of a wearer's face, and providing more comfort and convenience than the conventional facemasks.

  • Publication number: 20070061947
    Abstract: An adjuster for facemask comprising a lamellar structure and a plurality of stabilizing pillars on the lamellar structure, which each stabilizing pillar is comprised of a stabilizing piece installed in a stabilizing groove. When users wear facemasks, they insert ear-loops extending from one side of the facemask into the stabilizing groove of the respective-side stabilizing pillar on the lamellar structure, to be held fixed in the lamellar structure by respective stabilizing piece. Afterwards, the user places the adjuster to the back of the head and inserts the other ear-loops into their respective stabilizing grooves on respective stabilizing pillars to be held fixed by their respective stabilizing piece. Hence, the ear-loops are tucked to the bottom of the stabilizing groove of stabilizing pillar due to a pulling-force, and the facemask becomes firmly held fixed by the adjuster, wrapping around the head, which for this reason air leakage is reduced and security is heighten.
