Description

Mouth mask

The present invention relates to a kind of mouth mask, is about suiting in more working site such as manufacturing works, the dust of hospital, food etc. as being the disposable breathing mask of gurry product use with crossing in detail.

Disclose a kind of disposable sanitary mask in the Te Kaiping 9-149945 communique, covered the coating member of user's oral area at least by retractility sheet things such as nonwoven, integrally formed with the ear-hang parts that extend to the rear portion from the relative both sides of this coating member.Because this mouth mask is low in fit on saving man-hour thereby cost, this is very suitable for disposable breathing mask.

Above-mentioned known mouth mask, when being with the ear-hang parts, the ear-hang parts hang over the base portion of the basal part of the ear, and the ear-hang parts are promptly extended, and at this moment just have tension force and act in the narrow scope of base portion, and the people is felt bad.In this case, the ear-hang parts are in tension, and the people then feels otalgia.Problem of the present invention is exactly to eliminate the otalgia that respirator belt is given people.

In order to address the above problem, the present invention mainly is the mouth mask that is made of the coating member of corresponding user's oral area and the ear-hang parts that extend back from the coating member both sides.

Under this prerequisite, feature of the present invention is: but described ear-hang parts constituted by the composite sheet of elastic telescopic, described composite sheet is mutually stacked for one by having extensibility fiber elongate layer that constitutes and the elastic layer with elastic extension.

It below is most preferred embodiment of the present invention.

(1) described coating member and ear-hang parts, but be that composite sheet by a series of aforesaid elastic telescopics constitutes.

(2) but the composite sheet of described elastic telescopic is that the elongate layer that the two sides by described elastic layer and this elastic layer forms constitutes.

Fig. 1 is the oblique view of mouth mask.

Fig. 2 is the profile of II among Fig. 1-II line.

Fig. 3 is and the figure same with Fig. 2 that represents ear-hanger one example.

Fig. 4 is the plane that is different from mouth mask among Fig. 1.

With reference to the accompanying drawings the present invention is elaborated.

In diagram, represented mouth mask 1, constituted that wherein ear-hang parts 3 constitute and have the hole 4 that the cover ear is used by the coating member 2 of corresponding user's oral area and the ear-hang parts that rearward extend from coating member 2 both sides respectively 3 with squint mode.Coating member 2 by thermoplasticity simultaneously telescopic or non-flexible symmetrical a pair of the 1st 11 constitute, and by medial margin 13 overlapping, weld and form.But ear-hang parts 3 by thermoplasticity simultaneously again the sheet 12 of elastic shrinkage constitute, this sheet 12 dissolves and is engaged in the 1st lateral border 13.Because add in heating as the interior lateral border 13,13 at the junction surface of coating member 2 and to depress deposition, therefore, coating member 2 more has rigidity with ear-hang parts 3 compared with other place, makes mouth mask that guarantor's type function be arranged.

Accompanying drawing 2 is profiles of II among Fig. 1-II line.Forming the 2nd 12 of ear-hanger 3, is the integrated article that coincided by contact-making surface relative with mouth mask user skin and noncontact face.Wherein but contact-making surface is the elastic layer 16 of elastic telescopic; Noncontact face is stiff stretchable layers 17.The elastic layer 16 of example among the figure is made of the fiber of elastic extension, at least near the oral area to the folk prescription of ear to the fibrage that is flexible retractility.Be positioned at the elongate layer 17 in elastic layer 16 outsides, at least near the oral area to the folk prescription of ear to being stiff tensile fibrage.Two-

layer

16,17 can form one mutually like this by fibroplastic this of difference, heating and weld mutually together or by bonding agent bond together or by mechanical mode with its tangle up.At ear-hang parts 3 places, can be two these parts of handing at least in case to aforesaid folk prescription to elongation, the elastic layer 16 in this part is in elasticity aspect elongation, elongate layer 17 is done stiff elongation.In case hand is decontroled elongation from the ear-hang parts and promptly removed, the elastic layer in this part 16 flexibly is returned to life size like this, when the fiber majority of elongate layer 17 elongations produces gauffer, also is reduced to the size of elastic layer 16.When this part was extended once more, 17 of elongate layers need be opened wrinkle can need extending force that it is stretched out hardly, so only needed to satisfy make the power of elastic layer 16 elongations promptly enough.Can be easy to like this ear-hang parts 3 only are designed to some elastic telescopic easily.

In other words,, utilize such field, ear-hang parts 3 can be set the face that suitable length and flexible scope are suitable for the user most because comparing with the part of not extending once the part of extending of ear-hang parts 3 is in the flexible field of low stress.Particularly, make near the oral area with basal part of the ear base portion in the middle of the easy retractility of ear-hang parts 3 at place, its belt of not have in the past the ear-hang parts made by rubber strip etc. flexible at basal part of the ear base portion then, so also just do not had the sensation of otalgia.

Outside the illustrated ear-hang parts 3, elastic layer 16 can be constituted the outside, elongate layer 17 constitutes the internal layer of contact skin.The elongate layer 17 that constitutes by many fibers, fluffy and sense of touch good once will being produced many gauffers by elongation, thereby make fibrage can claim it is best improvement as the inboard.In addition, elastic layer 16 and skin contact with contact with rubber-like feel similar, so for the people who dislikes such skin tactility, preferably with elastic layer 16 as the outside.

Fig. 3 also is the legend of ear-hang parts, and it and Fig. 2 are same diagram faces.But the composite sheet of the elastic telescopic that the ear-hang parts 3 among Fig. 3 are 3-tier architectures to be formed all has elongate layer 17 on the two sides of elastic layer 16.In a single day a part of ear-hanger spare 3 of between oral area and ear this extends on fore-and-aft direction, elastic layer 16 is promptly done elastic elongation, and elongate layer 17 is promptly done non-resilient elongation.After elongation was removed, to the full-sized while, the elongated portion of elongate layer 17 produced many gauffers, shrinks with length with elastic layer 16 at elastic layer 16 elastic recoils.Diagram and ear-hang parts 3 shown in Figure 2 have been same purposes.

Fig. 4 is the plane of the mouth mask 1 different with Fig. 1.In this mouth mask, coating member 2 and ear-hang parts 3, but promptly be the incorporate composite sheet of a series of elastic telescopics of using in the ear-hang parts 3 among Fig. 2 or Fig. 3.This mouth mask 1 in use can be done the part elongation at fore-and-aft direction (left and right directions among the figure) in advance in addition.The mouth mask 1 of Fig. 4 is a kind of make simple, good disposable of usability.

In mouth mask 1 of the present invention, but in order to form the elastic layer 16 of composite sheet at least at ear-hang parts 3 with elastic telescopic, can use bonded fabric, the weaving cloth of the elasticity series that constitutes by the elastomer of thermoplastic synthetic resin or urethane fat etc., the elastic film that the fiber ripple of indefinite form etc. form.Elastic layer 16, at corresponding folk prescription to locating to have 30% at least, be preferably 100%, better then be 200% extending elasticity.On the other hand, but elongate layer 17 can use the non-resilient extensible materials series that is made of thermoplasticity synthetic resin such as polyethylene or polypropylene.This serial nonwoven, weave cotton cloth, atypic fiber ripple etc. engages with elastic layer 16.Elongate layer 17 should have 70% elongation at break at least, has identical degree or higher degree for well with the elastic elongation limit of elastic layer 16.Object lesson as elongate layer 17 comprises, do not extend or the fused mutually weight per unit area of polyethylene continuous fiber of low elongation is 20～200g/m ²Mutually fused continuous fiber and weight per unit area such as bonded fabric, the copolymer of ethylene, propylene or the copolymer of ethylene, propylene butylene be 20～200g/m ²

The present invention is a mouth mask, because the part in the ear-hang part is easily flexible, so the wider range that can draw back in advance maybe can be done narrow setting, can automatically adjust the user of the mouth mask that suits owing to the tension force of ear-hang parts.If at this easy telescopic section, if this position is set in the middle of oral area and the ear, the base portion place of mouth mask user's the basal part of the ear does not just have the contractility effect of ear-hang parts so, and such mouth mask will bring good usability to the user.
