The specific embodiment

Below, with reference to accompanying drawing, the embodiment of disposable breathing mask of the present utility model is described.

Fig. 1 is the oblique view of disposable breathing mask 1.Mouth mask 1 comprises near the oral cavity that covers the wearer and nasal cavity and can collude the annulus 3 that is hung on ear with the main body 2 of its facial contact and the left and right sides that is positioned at main body 2.Mouth mask 1 is with respect to first junction surface, 4 symmetries of front surface central authorities, and main body 2 is made of the front surface tabs 5 of the pair of right and left that is bonded with each other at 4 places, first junction surface of extending along its longitudinal direction.Annulus 3 is made of the side tabs 7 of pair of right and left, the side tabs 7 of this pair of right and left is separated and is engaged with front surface tabs 5 at 6 places, second junction surface of extending along above-mentioned longitudinal direction at transverse direction with respect to first junction surface 4, and has and collude the perforate 8 that is hung on ear.Below so the engagement relationship of two front surface tabs 5 and side tabs 7 is described, two front surface tabs 5 have medial margin 5a and lateral border 5b, wherein, medial margin 5a extends along above-mentioned longitudinal direction, and central portion is linearly, the top and the bottom tilted rearward, lateral border 5b is parallel with the linearity central portion of medial margin 5a to be extended along above-mentioned longitudinal direction, and medial margin 5a is both hands and closes up shape and be bonded with each other with being strip, thereby forms first junction surface 4; Two sides tabs 7 has the medial margin 7a that extends along above-mentioned longitudinal direction linearity and is the lateral border 7b of circular-arc extension to foreign side, and medial margin 7a engages formation second junction surface 6 with the stripes of the inner face of the lateral border 5b of two front surface tabs 5.Like this first and second junction surface 4,6 that engages aspect rigidity, than high except the zone of the front surface tabs 5 at these junction surfaces and side tabs 7, has mouth mask integral body, especially the conformal function of its main body 2.In addition, first junction surface 4 of main body 2 is made into the shape to foreign side's projection of mouth mask 1, brings unplessantness displeasure to avoid contacting wearer's nose to it; And first junction surface 4 be made into shape to foreign side's bending of mouth mask 1 so that can be near wearer's oral cavity and around the nasal cavity slot milling ground with its covering.And then front surface tabs 5 and side tabs 7 are with near the form formation that increases gradually to first junction surface 4 of the lateral border 7b of tabs 7 from the side of its height dimension.Therefore, mouth mask is under it wears state, because the rearward tractive force of annulus 3 is from disperseing to first junction surface 4 near second junction surface 6, so front surface tabs 5 can not oppressed wearer's face, that is, contact substantially uniformly, can not bring unplessantness displeasure to the wearer with its face.

Front surface tabs 5 is a vapor-permeable type, and low than the extensibility or the retractility of side tabs 7, and the tension force corresponding to the left and right directions of wear mouth mask 1 time effect is difficult to elongation relatively.This just means that front surface tabs 5 is essentially non-extensibility or non-retractility.This front surface tabs 5 can be formed by following material: the yarn fabric that nonwoven, yarn fabric, plastics system net, the natural fiber of the molten bonded non-woven fabrics that is made of the thermoplastic synthetic fiber or spun-bonded non-woven fabrics etc. constitutes or its sandwich etc.

Side tabs 7 is preferably vapor-permeable type, and it constitutes: the tension force corresponding to the left and right directions of wear mouth mask 1 time effect demonstrates higher retractility than front surface tabs 5.This tabs 7 heat-treat by the net that the composite fibre of crispaturaing by being heated is constituted and the nonwoven with retractility form.

Fig. 2 is the oblique view of partly cut-away of mouth mask 1 of the example of expression another embodiment of the present utility model.The front surface tabs 5 of the main body of this mouth mask 1 is made by the sandwich of internal layer tabs 10 and outer tabs 11, the extension of internal layer tabs 10 for stretching out to main body 2 one sides from the side tabs 7 of annulus 3, outer tabs 11 is used than internal layer tabs 10 extensibilities or the low gas permeability tablet of

retractility.Ectonexine tabs

10,11 at first and second junction surface 4,6 and other appointed part places engage.

Fig. 3 is the side view of mouth mask 1 of the example of the different embodiment of another one.Constituting of this mouth mask 1: U font cut-crease lines 13 is set on the side tabs 7 of annulus 3 and the inboard of U word is divided into the cut-crease lines 14 that 2 parts, an end extend to the periphery of side tabs 7 along longitudinal direction forming, when when wearing mouth mask 1, the rearward end of side tabs 7 rearward being drawn, expansion and form perforate 8 shown in imaginary line 7A, and can collude and be hung on ear.So constitute, make side tabs 7 little than the mouth mask among Fig. 11, can save the use material.

In addition, though do not illustrate, the utility model also comprises such example: front surface tabs 5 also can form by a slice thermoplastic sheet material is converted into two parts, in this case, flaky material can be formed junction surface 4 by hot pressing.

Disposable breathing mask of the present utility model, its annulus is made of the nonwoven with retractility and gas permeability, so the skin that the part around the ear has picture cloth feels and gas permeability, wears and feels good, even wear for a long time, the phenomenon of annulus incision ear can not take place yet.Especially mouth mask integral body, particularly the conformal function in two zones between first and second junction surface are being brought into play in first and second junction surface that is rich in rigidity most in the mouth mask, therefore, can keep mouth mask to be in the suitable state of wearing always, nor can stop up near the oral cavity and the phenomenon of nasal cavity, breathing and session are easily carried out.So particularly conduct offers in the practical application of the mouth mask of wearing when the borough chief of hospital time and operation, has benefit.
