Abstract

The present invention relates to a personal respiratory protection device, in particular, such a device comprising a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length.

First claim

1 . Personal respiratory protection device for use by a wearer, comprising:
a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length, wherein the gasket is formed of a flexible elastomeric material and is contoured, the contour comprising a ridge that projects away from the periphery, and wherein the ridge is adapted to be deformable and deform towards the periphery.

2 . Device of claim 1 , further comprising headband means to secure the personal respiratory device onto a wearer such that the gasket flexes and conforms to the facial features of the wearer.

3 . Device of claim 2 , wherein the headband means are adjustable, such that when the adjustable headband means are adjusted the gasket flexes and conforms to the facial features of the wearer.

4 . Device of claim 3 , wherein when the gasket flexes, the ridge deforms towards the periphery and creates an accommodation space.

5 . Device of claim 4 , wherein the accommodation space is adapted to accommodate eyewear.

6 . Device of claim 5 , wherein the eyewear does not impinge upon the gasket.

7 . Device of claim 1 , wherein the ridge is provided with an indent adapted to accommodate the nose of a wearer.

8 . Device of claim 1 , wherein the ridge is deformable such that the gasket fits substantially flush against the nose and cheeks of a wearer.

9 . Device of claim 1 , wherein the gasket extends along the entire periphery of the respirator body.

10 . Device of claim 9 , wherein the gasket fits substantially flush against the nose, cheeks and chin of a wearer.

11 . Device of claim 1 , wherein the ridge is formed in the region of the gasket that contacts the nose of a wearer during use.

12 . Device of claim 1 , wherein the contour is substantially V-shaped.

13 . Device of claim 1 , wherein the ridge is formed from a local increase in thickness of elastomeric material.

14 . Device of claim 1 , wherein the gasket comprises a thermoplastic elastomer (TPE).

15 . (canceled)

16 . Device of claim 1 , wherein the filter media is in the form of a cover, and the respirator body comprises an inner cup shaped support and the filter media is overlaid on the inner cup shaped support.

17 . Device of claim 16 , wherein the cover and the inner cup shaped support are joined at the periphery of the respirator body.

18 . Device of claim 1 , wherein the respirator body comprises at least two panels.

19 . Device of claim 1 , wherein the device is a maintenance-free respirator device.

20 . Device of claim 1 , wherein the gasket comprises a sheet-like elastomeric material.

21 . Device of claim 1 , wherein the gasket is provided with an aperture adapted to accommodate the nose and mouth of a wearer.
