  • Publication number: 20140216477
    Abstract: A pleated molded filtering face piece respirator to be worn upon the face of a wearer and for providing filtering including at least one layer of moldable flexible plastic material formed from openwork flexible plastic material for providing a plurality of perforations for allowing for the free passage of air through the openwork plastic. A layer of moldable filter material for filtering impurities in the air, the one layer of flexible plastic material formed from openwork flexible plastic material and the layer of filter material for filtering impurities in the air lying one on top of the other to form a moldable multilayer of flexible plastic material and filter material. The moldable multilayer of flexible plastic material and filter material are pleated into pleated material and molded to form the pleated filtering face piece respirator to a desired configuration where the one layer of openwork flexible plastic material forms a support layer to carry the layer of filter material.

  • Patent number: 8413663
    Abstract: A hearing protective earplug for insertion into the human ear canal of a user where the human ear canal has sidewalls and a typical curved portion. A soft resilient body has a main body element with a front end for insertion in the human ear canal. An elongated stem has two ends with one end attached to the main body element. The stem extends outward from the main body element and away from the front end. The other end of the stem forms a handle portion of the stem. The stem is sufficiently stiff as to allow manipulation of the main body element into the ear canal of the user. The stem member has a crooked or wavy configuration within the ear canal as it extends outward from the main body to the handle portion of the stem. As the front end of the main body element is inserted into the ear canal, the stem member is rotated during insertion with the handle portion to fit around the typical curved portion in the human ear canal.

  • Publication number: 20120030912
    Abstract: An adjustable buckle located around a resilience strap for a respirator including a resilient strap material having a particular length, width and thickness. An adjustable buckle is molded around the strap at a particular position and formed of two interlocking members each located at an end position of the strap and having at least one portion that interlocks with a corresponding portion of the other member. This provide for locking and unlocking of the members with each other. At least one of the interlocking members includes a plurality of such portions that interlocks with the corresponding portion of the other member. The plurality of portions are spaced from each other along the length of the strap so that an individual one of the plurality of portions may be interlocked with the corresponding portion of the other member to adjust the length of the strap.
