Definitions

  • the present invention refers to a face seal for protective masks.
  • the protective masks at present in use comprise a face-shield which acts both as support of the ocular surface and of the filter with which the mask is provided and as a seal on the user's face.
  • the face-shield is made by a single piece of rubber which is sharpened at the edge in order to be particularly flexible and soft to adhere hermetically to the face with as much comfort as possible, acting as a seal.
  • the rubber of the face-shield is on the contrary thick and presents a limited flexibility so that it supports rigidly the filter(s) and the ocular surface of the mask.
  • the object of the present invention is to provide a face seal associable to a face-shield, structured in whatsoever way, for protective masks, able to avoid the above mentioned drawbacks, namely to give the necessary tightness without weariness or inflammation of the circumferential portion of the face with which it interacts; said face seal is not affected by the deformations of the face-shield of the mask caused by the weight of the filter(s) and of the ocular surface.
  • Another object of the present invention is to allow many people to use the same mask reducing the number of the sizes necessary to satisfy a population of persons.
  • a face seal for protective masks provided with a face-shield, characterized by the fact that siad face seal presents an annular development and is provided with means for its fit to the edge of the face-shield of the mask and with means for the tightness between said edge and the user's face, having a bellows section.
  • the main advantages obtained by the use of such face seal on protective masks are the following: - improved comfort of use of the mask with the highest guarantee of tightness; - reduction of the number of necessary sizes with consequent standardization of the production of the masks; - possibility to make the face seal by a type of rubber or other materials which privilege the characteristics of anti-allergy and softness in restect to those of durability, being possible to replace periodically and easy the possibly worn face seal with another one.
  • the face seal presents an annular development which allows it to anchor to an edge 2 of a face-shield 3 for instance of rigid type.
  • the face seal 1 comprises fitting means cooperating with the edge 2 and tightness means operating between said edge 2 and the user's face (not shown).
  • the tightness means of the face seal comprise a bellows 4 in which a first 5 and a second 6 annular foil are reciprocally hinged along a line 7 so that they form between themselves an angle "alpha" with concavity towards the interior of the face-shield 3.
  • the second annular foil 6 extends itself to form a chin-­latch by the lower part of the face-shield.
  • the means for the fit of the face seal 1 to the edge 2 of the face-shield 3 comprise a couple of annular flaps (internal 10 and external 11) joined together to form a U-shaped structure fitted on the edge 2 of the face-­shield 3.
  • the external flap 11 is pressed against the edge 2 by a metallic hooping 12 made, according to the requirements, even by many pieces and cooperating also with a step 13 associated to said edge 2.
  • the face seal 1 can be fitted, with all the related advantages, also to a soft face-shield with the sole condition that the edge 2 is rigid and therefore indipendent from the means which fit it to the face-­shield 3.
  • the second annular foil 6 comes in contact with the user's face (not shown) and rotates elastically around a hinge line approaching the first foil 5.
  • the concave angle "alpha" between said foils reduces itself till the elastic force generated by the face seal 1 balances the elastic force produced by the means of fit of the mask to the user's head (not shown); said means are usually formed by elastic belts connected directly to the face-shield 3 of the mask.
  • the connecting baffle 8 is present and cooperates to balance said force by its deformation.
