Facemask structure improvement

BACKGROUND OF THE INVENTION

1. Field of the Invention

0001The present invention relates to facemasks, but more precisely, it is an improvement on existing facemask structures that renders them more three-dimensional as to fit better to the face of the wearer.

2. Description of Related Art

0002The major function of a facemask lies in creating a special breathing cavity, which harmful substances in the air are kept from entering that cavity, and harmful substances exhaled by the wearer are prevented from exiting that cavity. This keeps the hazardous substances in the air from being inhaled, and the exhaled hazardous substances from affecting the environment.

0003Different facemasks are used for different needs. Generally, the common facemasks are disposable and are usually referred to as simple facemasks. A simple facemask is one in which the filtering materials themselves are made into the face configuration, in a way that the filtering face configuration comes in direct contact with the face of the wearer. The simple facemask is well known and popular since it is cheap, easy to use, and widely available.

0004Referring to Fig. 1, a disposable facemask as disclosed includes a mask body 80 and two ear bands 90. The mask body 80 is made of a filtering material and is rectangular in shape, covering over the nose and mouth of the wearer. The two ear bands 90 are respectively connected to the two sides of the mask body 80 and loops around the ears of the wearer, so that the mask body 80 can be held in place to cover over the nose and mouth of the wearer.

0005The disposable facemask is generally made planar shaped, with ear bands 90 thereof used to loop around the ears of the wearer. Since people's faces are not planar, facemasks such as these have serious leakage problems. To resolve this problem, a plurality of folds 81 are placed on the mask body 80 of a disposable facemask extending horizontally, forming a cambered shape to cover over part of the face of the wearer. See e.g. <patcit id="pcit0001" dnum="US5699792A"><text>US 5699792</text></patcit>.

0006However, the afore said conventional facemask structure has a rather cramped shape because the mask body 80 merely provides a plurality of horizontal extending folds 81 and thus the mask body 80 can only be stretched vertically. Hence, the conventional facemask cannot conform closely to the contours of the face of the wearer, allowing gaps to form causing leakages. Moreover, the conventional facemask provides a very limited cavity for the wearer to breath and converse, and comes in direct contact with mouth of the wearer when he or she tries to speak.

0007Therefore, due to these inconvenience and disadvantages, the conventional facemask was meant to be improved.

SUMMARY OF THE INVENTION

0008The objective of the present invention is to provide a facemask which can be stretched both vertically and horizontally, thus being better three-dimensionally shaped than conventional facemask, and conforming better to the contour of the wearer's face, effectively avoiding leaks while giving the wearer the convenience of a better breathing cavity which would also make conversing easy.

0009To meet the objective described above, this invention provides an improvement on the existing facemask, wherein the new facemask structure includes a mask body having two pluralities of folds as well as ear bands that respectively connects to the two sides of the mask body. The two pluralities of folds consist of a first plurality of folds extending horizontally on the mask body, and a plurality of second folds extending vertically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

0011Referring to Figs. 2 and 3, the facemask structure improvement provided by this invention includes a mask body 10 made of a multi-layered filtering material and two ear bands 20. The mask body 10 is rectangular in shape and covers the nose and mouth of the wearer.

0012The first plurality of folds 11 is placed extending horizontally on the mask body 10. A respective first fixing section 12 is formed by thermal pressing or stitching at the top, bottom, right and left edges of the mask body 10. The first fixing sections 12 at the right and left edges of the mask body 10 fix in place the two ends of the first plurality of folds 11 along with the two ear bands 20, such that the two ear bands 20 are respectively fixed and connected to the right and left sides of the mask body 10, thereby to be looped around the ears of the wearer when used.

0013Furthermore, a plurality of second folds 13 is placed on the mask body 10. In this embodiment, two of the second folds 13 are shown. The second folds 13 extend vertically on the mask body 10. A plurality of second fixing sections 14 are formed by thermal pressing or stitching at the top and bottom edges of the mask body 10, corresponding to the two ends of the second folds 13. The second fixing sections 14 are used to held fixed the two ends of the second folds 13.

0014In addition, a flexible nose adjustment piece 15 can be placed near the upper edge of the mask body 10 in this invention. When the facemask is worn, the nose adjustment piece 15 can be shaped to ensure that the upper edge of the mask body 10 nicely conforms to the contours of the wearer's face, such that no gap can form and the facemask remains airtight.

0015In this invention, by means of the first plurality of folds 11 extending horizontally on the mask body 10, the mask body 10 can be stretched vertically. By means of the second folds 13 extending vertically on the mask body 10, the mask body 10 can be stretched horizontally. Hence, the mask body 10 of this invention is more three-dimensionally shaped than conventional face masks, in a way that it fits better to the contours on the face of the wearer, as shown in Fig. 4, effectively preventing leakages, and giving the wearer greater comfort and convenience.

0016Moreover, since the facemask of this invention is better three-dimensionally shaped by means of a simple structural design, the cost of producing the facemask is cheaper.

0017The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all aspects as illustrative and not restrictive. The scope of this invention is indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning or the range of equivalency of the claims are therefore intended to be embraced therein.
