Description

Three-dimensional mask

Technical field

The present invention relates to cover the three-dimensional mask at object position of the face of the mouth that comprises the user and nasal cavity.

Background technology

Past, this mouth mask that uses under various situations nearly all is with stacked main parts that forms such as the gauze of multi-disc rectangle or nonwoven, and (hereinafter the mouth mask with this form abbreviates " existing plane face mask " as to set up the rubber rope that is used to hang on the ear in the form of a ring in the end, the left and right sides of this main part.)。But in this existing plane face mask, gauze etc. contact with user's mouth, and meeting such as this gauze is elongated and become moist along with service time, are difficult to the problem of being breathed by mouth or nose thereby exist.

So the plane face mask of form that has occurred being provided with fold along width (be folded into pleated and form gauffer) on this main part that is made of gauze etc. is (for example, with reference to patent documentation 1.)。The plane face mask of this form is flat condition before use, but can form three-dimensional shape according to the projection of mouth shape and nose in use.But also very fast appearance distortion can't thoroughly solve the problem that breathing can become difficult to the plane face mask of this form because the ability (shape retention) of lasting maintenance three-dimensional shape is relatively poor.

So, having occurred just main part being formed the mouth mask of three-dimensional shape such as cup-shaped in recent years and just main part has been implemented the mouth mask of stereo clipping in the fabrication stage in the fabrication stage, this mouth mask is called three-dimensional mask, has been subjected to people's welcome.As the latter's carrying out the mouth mask of stereo clipping, following mouth mask is for example arranged: main part left part and main part right sides that material is different partially overlap, these two parts are got up to constitute the central portion of main part width (for example, with reference to patent documentation 2 along the engaged at end of a side.)。This three-dimensional mask is flat condition before use, in use will left part and the right side launch to form three-dimensional shape between dividing so that the corners of the mouth and nose can be attached between this left part and the right side branch.

But, for these three-dimensional masks, though the shape retention height big advantage that is one, but just because of this, can not be out of shape according to user's face on the contrary, above nose or its and form the gap between the main part, thereby cause malaria to pass through to rise on this gap, glasses etc. are hazed.

The specific embodiment

Below embodiments of the present invention are described.

[definition etc.]

In this specification, so-called three-dimensional mask is meant that in principle main part is the mouth mask of three-dimensional shape when using.Therefore, three-dimensional mask comprises: for example, (stereo clipping is meant that for making finished product be that three-dimensional shape is got shape, cutting to main part through stereo clipping in the fabrication stage.), even be the mouth mask of three-dimensional shape when using as flat condition before using; Main part forms the mouth mask of cup-shaped etc. in the fabrication stage, is exactly the mouth mask of three-dimensional shape before promptly using; Deng.

But, even main part is the mouth mask of three-dimensional shape for flat condition before use in use, also have and a kind ofly belong to plane face mask and be not included in the three-dimensional mask of this specification, that is: be provided with fold at main part, when the top and bottom of tractive main part so that they are when separating, fold launches so that pars intermedia bloats laterally, and its bulk deformation is a three-dimensional shape.Have the mouth mask of gauffer because shape retention is relatively poor and easily deformable, thereby be inferior to three-dimensional mask aspect being convenient to breathe, because air is difficult to rise, its character approaches common (existing) plane face mask conversely speaking.Therefore, satisfy prerequisite of the present invention (problem) because this mouth mask is insufficient, thereby it is classified as plane face mask rather than three-dimensional mask in this manual.In addition, in the art, will utilize the effect of fold usually and become three-dimensional mouth mask and be categorized as plane face mask.

[basic structure]

Fig. 1 shows the three-dimensional mask 1 of the manner.This three-dimensional mask 1 mainly has main part 2 and holding division 3, described main part 2 covers the object position (with reference to Fig. 3,5,7) of the face that comprises mouth 8 and nasal cavity 7, described holding division 3 extends out from side end 2e, the 2e of this main part 2, and it is used for by this side end of tractive 2e, 2e main part 2 being fixed at face.

Main part 2 is made of left part 2L and the right side part 2R with respect to width Central Line symmetry.And these two part 2L, 2R are made by smooth material and are bonded together at the edge part 4 of width center side.And this bonding part 4 forms the curved shape that pars intermedia bloats more laterally than both sides up and down.

On the other hand, holding division 3 is the ring-type flat member with the opening 5 that is used to hang on the ear, and it is bonded on main part 2 left and right sides end 2e, the 2e.

Main part 2 and holding division 3 are smooth under left part 2L and non-working condition that right side part 2R overlaps.Relative therewith, under the user mode of launching between with left part 2L and right side part 2R (shown position), main part 2 is three-dimensional shape.Under this state, put on this three-dimensional mask 1 so that its covering when comprising the object position of face of user's mouth 8 and nasal cavity 7, can cover under the state that leaves the space around mouth 8 and the nasal cavity 7.

In the manner, be main part 2 to be formed with the different parts of holding division 3 usefulness and both are bonded together, but also can form main part 2 and holding division 3 with single parts as shown in Figure 2.

And closing line 4 also needn't form along the vertical direction, though not shown, for example also can broad ways form.

Main part 2 can be illustrated in figure 1 as single layer structure, but is preferably the sandwich construction that has the inside piece 2B that comprises more than 1 layer or 2 layers as shown in Figure 2 and comprise the lateral film 2A more than 1 layer or 2 layers equally.In this case, for example can be as shown in Figure 2, form lateral film 2A (or inside piece 2B) and holding division 3 with single parts, go up lamination inside piece 2B (or lateral film 2A) by inner surface (or outer surface), just main part 2 can be made sandwich construction in the part that is equivalent to this main part 2.

When becoming sandwich construction, be preferably wherein one deck at least and be and have the functional layer that function, aromatic function, virus-anaphylactogen deactivation function, antibacterial functions, the shape of for example filtering dust etc. keep function etc.For this functional layer, it is also conceivable that can be with respect to the form of main part 2 disassembled and assembled freelies.

And sandwich construction as described above also goes for holding division 3.

[feature structure]

(the 1st mode)

Plane when Fig. 3 shows from the three-dimensional mask 1 of inboard (user's side) observation the manner, Fig. 4 shows along the profile of the I-I line of Fig. 3.

The three-dimensional mask 1 of the manner is characterised in that: above the position of the covering nasal cavity 7 of main part 2 inner surfaces, transversely be formed with to the outstanding protrusion tab 9 in oblique below, this protrusion tab 9 is by forming lateral film 2A and the protruding to the inside folding of inside piece 2B.In this three-dimensional mask 1, this protrusion tab 9 has played the effect of valve with respect to the humid airs in the mouth mask 2, owing to suppressed the rising of the humid air in the mouth mask 2, thereby can not make humid air be discharged to the top in the mouth mask 2 and glasses etc. are hazed.And this protrusion tab 9 also has and stops that main part 2 surpasses necessary limit ground to the close function of face.

Protrusion tab 9 is can be in advance just outstanding to oblique below, but is preferably as follows structure from can gently contacting facial angle, that is: when utilizing holding division 3 to fix, when side end 2e, the 2e of tractive main part 2 to oblique below outstanding (erecting).As this structure that erects, can adopt at the top of protrusion tab 9 structure, for example with identical structure such as widely used three-dimensional edge and standing gather in disposable paper diaper now with the fixing not shown elastic telescopic parts such as rubber rope of extended state.

(the 2nd mode)

Plane when Fig. 5 shows from the three-dimensional mask 1 of inboard (user's side) observation the manner, Fig. 6 shows along the profile of the II-II line of Fig. 5.

Except the feature identical with the three-dimensional mask 1 of the 1st mode, promptly have beyond the protrusion tab 9, the three-dimensional mask 1 of the manner is characterised in that, also below the position of the covering mouth 8 of main part 2 inner surfaces, transversely be formed with outstanding obliquely upward protrusion tab 11, this protrusion tab 11 is by forming lateral film 2A and the protruding to the inside folding of inside piece 2B.In this three-dimensional mask 1,, thereby needn't worry that pollen etc. is entered by this gap because this protrusion tab 11 has been blocked the space between main part 2 and user's the face.And this protrusion tab 11 also has and stops that main part 2 surpasses necessary limit ground to the close function of face.

This protrusion tab 11 is also can be in advance just outstanding obliquely upward, but preferably with protrusion tab 9 is equally, when utilizing holding division 3 to fix, gives prominence to the structure of (erecting) obliquely upward when side end 2e, the 2e of tractive main part 2.And this structure that erects also can adopt the structure same with protrusion tab 9.

(the 3rd mode)

Plane when Fig. 7 shows from the three-dimensional mask 1 of inboard (user's side) observation the manner, Fig. 8 shows along the profile of the III-III line of Fig. 7.

Except the feature identical with the three-dimensional mask 1 of the 2nd mode, promptly have beyond protrusion tab 9 and the protrusion tab 11, the three-dimensional mask 1 of the manner is characterised in that, also at the position of the covering nasal cavity 7 of main part 2 inner surfaces and cover between the position of mouth 8, transversely be formed with to the outstanding protrusion tab 12 in oblique below, this protrusion tab 12 is by forming lateral film 2A and the protruding to the inside folding of inside piece 2B.For the ease of breathing, be the place that needs most the space between nasal cavity 7 and the mouth 8,,, be subjected to external force easily and be out of shape because the position that main part 2 covers these spaces is the place that bloats most.But, in this three-dimensional mask 1,, thereby guaranteed the space because protrusion tab 11 can stop that the position between main part 2 covering nasal cavities 7 and the mouth 8 close to face with surpassing necessary limit.And, because the guaranteeing of this space, thereby have the advantage that can not make lipstick come off, can not fluff owing to friction fibers such as beards.

This protrusion tab 12 is also can be in advance just outstanding to oblique below, but preferably with protrusion tab 9 is equally, when utilizing holding division 3 to fix, gives prominence to the structure of (erecting) to oblique below when side end 2e, the 2e of tractive main part 2.And this structure that erects also can adopt the structure identical with protrusion tab 9.

(the 4th mode)

The three-dimensional mask 1 of this mode is shown in Fig. 9 (1), and protrusion tab 9 is only formed by the protruding folding of inside piece 2B, and lateral film 2A is made by the material that has retractility at least on above-below direction.Thus, shown in Fig. 9 (2), main part 2 stretches at the position that has protrusion tab 9, just can become the also suitable mouth mask for the people of long face.Certainly, this structure also can adopt in protrusion tab 11 and protrusion tab 12.

(other modes)

In the above-mentioned the 1st～4 the mode, formed protrusion tab 9,11,12 with the sheet material that constitutes main part 2.But the present invention is not limited to this, for example the sheet material different with the sheet material that constitutes main part 2 can be bonded on the main part 2, forms protrusion tab 9,11,12 with this different sheet material.

And the sheet material 2A, the 2B that turn back that constitutes protrusion tab 9,11,12 also can utilize fusion such as ultrasonic wave to become one.

[constituting the material of each parts]

(main part)

As the material of main part 2 (or each sheet material 2A, 2B or constitute the layer of each sheet material 2A, 2B), can suitably set, for example can use among the JIS Z 0208 air permeability of regulation to be 300g/m ²The poromeric material that hr is above.

As this material, except porous matter sheet material with a large amount of air-vents, net material, can also enumerate weave cotton cloth, short fiber or long fibre aggregate and their laminate such as nonwoven.

Use under the situation of fiber assembly, it for which kind of raw fibre is not particularly limited.For example can enumerate olefines such as polyethylene or polypropylene, polyesters, natural fibers such as regenerated fibers such as synthetic fibers, artificial silk, CUP, cotton such as polyamide-based etc., or be selected from wherein two or more composite fibre.

And then, use under the situation of nonwoven, use which kind of processing method to make and all can.As processing method, can enumerate known method: for example water acupuncture manipulation, spun-bond process, heat viscosity method, meltblown, needle point method, hot gas (air-through) method etc.And,, can use such lamination type nonwoven such as SMS nonwoven or SMMS nonwoven with the layer that constitutes by superfine fibre (about diameter 0.5～5 μ m) in order to improve the performance of blocking-up pollen or fine dust.

Use under the situation of fiber assembly, can make weight per unit area is 15～70gsm, is in particular 20～50gsm.If the not enough 15gsm of weight per unit area then goes wrong aspect intensity easily.Particularly holding division 3 is because breakage may appear in wearing and taking repeatedly.On the other hand, if weight per unit area surpasses 70gsm, then the sense of touch variation may make the user be not easy to speak, or scratch user's skin.

(holding division and lateral film) with retractility

As the material of holding division 3, can select the material same with main part 2, select to be rich in retractility and elasticity and the material lighter but be preferably to the stimulation of skin.

As holding division 3 and material with lateral film 2A of retractility, except for example at the about both sides applying nonwoven of elastic extension film and implement the laminated nonwoven fabric that processes of raising retractilities such as acupuncture processing as required, by the nethike embrane that is made of the composite fibre with hot crimpiness being heat-treated the flexible nonwoven fabrics that obtains, can also use following nonwoven well, that is: by fitting a pair of nonwoven and between nonwoven, accompany simultaneously flexible nonwoven fabrics that elastic telescopic parts such as rubber covered wire form etc.Certainly, for holding division 3, in addition can also use for example rubber such as flat rubber, round rubber.In addition, these materials and the material that can be used in main part 2 can also be combined by lamination etc., the material that obtains is used for holding division 3.

(other)
