Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a multilayer mask.
[0002]
[Prior art]
Conventionally, masks have been used to prevent infection by viruses such as influenza that is prevalent due to air infection or droplet infection in a crowded place.
[0003]
In recent years, pathogenic viruses such as severe acute respiratory syndrome (SARS) have become prevalent and have become a major social problem.
[0004]
Furthermore, there is a current situation in which it is not known what unknown virus will occur in the future, and there is an increasing sense of anxiety about viruses with strong infectivity.
[0005]
As such an anti-virus mask, a mask member is formed in multiple layers, and each layer is provided with a specific function such as a sterilizing function or a virus collecting function.
[0006]
For example, a mask is formed in multiple layers with a photocatalyst layer and a carbon fiber layer, and when the virus passes through the mask, it is sterilized with the photocatalyst layer, and the virus is adsorbed on the carbon fiber layer, so that the virus enters the human body. There was a thing of the structure which prevents (refer patent document 1).
[0007]

[Problems to be solved by the invention]
However, since the conventional multi-layer mask uses a photocatalyst device, light is required during use, so that the bactericidal effect cannot be expected in a dark place, and the use form is limited. is there.
[0009]
Further, as described above, if a mask is formed from a photocatalyst layer, a carbon fiber layer, or the like to obtain a sterilization and high collection effect, even if two layers are formed, the cost becomes high. In order to prevent the spread of viruses, the area (including the country) where infection has been confirmed and the residents in the vicinity can obtain it without burden, or it is inexpensive enough to be distributed to residents by the country or local government free of charge. In addition, a mask having a sufficient function is desired.
[0010]
Further, some viruses may infect from the mucous membrane, and even if the nose and mouth are covered with the above-described conventional multilayer mask, there is a risk that the virus may adhere to the mucous membrane of the eye, for example.
[0011]
[Means for Solving the Problems]
Accordingly, in the present invention according to claim 1, in a multilayer mask configured by laminating a plurality of mask members, at least a synthetic fiber mask member made of a chemical fiber, a nonwoven fabric mask member made of a nonwoven fabric, and a cotton fabric Or a non-woven fabric mask member made of gauze, wherein the non-woven fabric mask member is composed of a plurality of non-woven fabric mask members each having a different roughness. Members, a relatively coarse first nonwoven fabric mask member, a cotton fabric mask member, and a relatively fine second nonwoven fabric mask member are laminated in this order, and the innermost of the mask members. A strip-shaped metal foil that is deformable along the face shape of the user is attached to the vicinity of the upper end of the inner surface of the second nonwoven fabric mask member disposed on the mask, The chemical fiber mask member which is disposed closest to the outside of the timber is formed by a chemical fiber having a chargeability, fitted with eye protector having a light-transmitting property that covers the eyes of the user to one of said mask member.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a multilayer mask configured by laminating a plurality of mask members, and at least a synthetic fiber mask member made of a chemical fiber, a nonwoven fabric mask member made of a nonwoven fabric, and a cotton fabric mask made of cotton fabric or gauze fabric It is set as the structure which has a member for use.
[0017]
In this way, by using a plurality of inexpensive materials that can be easily obtained as mask members and using them in multiple layers, it is possible to reliably block viruses and prevent entry into the human body while being inexpensive. A functional mask can be provided.
[0018]
In particular, for the synthetic fiber mask member, for example, a polyester cloth may be used and can be charged with static electricity, so that the virus can be effectively adsorbed and collected on the surface.
[0019]
Moreover, it is preferable that the nonwoven fabric mask member uses a plurality of nonwoven fabric mask members each having a different roughness.
[0020]
For example, a first non-woven fabric mask member having a relatively coarse mesh and a second non-woven fabric mask member having a relatively fine mesh can be used.
[0021]
Thereby, most viruses can be adsorbed by the first nonwoven fabric mask member, and the remaining viruses can be reliably adsorbed by the second nonwoven fabric mask member.
[0022]
In addition, the cotton mask member is made of cotton fabric, but a thin gauze fabric that is a woven fabric similar to cotton cloth may be used as the cotton fabric, and as a cotton mask member in the present invention, In addition to cotton cloth, gauze fabric is also included.
[0023]
In order to make use of the respective functions, how to stack the plurality of mask members is a first non-woven fabric mask member that is relatively coarser than the outside in the mounted state, and a second that is relatively finer. The nonwoven fabric mask member, the synthetic fiber mask member, and the cotton mask member may be laminated in this order.
[0024]
According to this configuration, first, most of the virus is adsorbed by the first nonwoven fabric mask member, the amount of virus adsorption on the inner layer side is reduced, and the second nonwoven fabric mask member reliably blocks the virus. And the virus which passed each member for nonwoven fabric masks is reliably interrupted | blocked by the member for synthetic fiber masks which charged static electricity. Further, the cotton mask member can reliably block moisture from the outside and adsorb moisture from the user's mouth to prevent the mask from deteriorating. Moreover, a feeling of use becomes favorable by arrange | positioning the member for cotton cloth masks in the position which touches a user's skin directly.
[0025]
By the way, in the multilayer mask having the above-described configuration, a strip-shaped metal foil that can be deformed into a desired shape can be attached to any one of the mask members.
[0026]
With such a configuration, it is possible to change the three-dimensional shape of the mask so as to best fit the face shape of the user who wears it or to obtain a desired wearing feeling, thereby significantly improving usability. Can do.
[0027]
As another embodiment of the present invention, a translucent eye protector that covers the eyes of the user can be attached to any of the mask members.
[0028]
In other words, it is possible to infect from the mucous membrane by receiving droplets containing the virus, but by providing the above eye protector, it is possible to prevent the virus from adhering to the mucosa of the eye and infecting it, and more reliable infection prevention Become.
[0029]
【Example】
In the following, embodiments of the present invention will be described in detail with reference to the drawings.
[0030]
Example 1
1 is an overall perspective view of the multilayer mask according to the first embodiment, FIG. 2 is an overall perspective view of an eye protector attached to the multilayer mask, and FIG. 3 is an overall view when the multilayer mask is mounted. It is explanatory drawing. A shown in FIGS. 1 to 3 is a multilayer mask according to the first embodiment, and is configured by attaching a head strap B to a mask body M. FIG.
[0031]
The mask body M includes a first nonwoven fabric mask member 1, a second nonwoven fabric mask member 2 that is polymerized on the inner side (user H side) of the first nonwoven fabric mask member 1, and the second The synthetic fiber mask member 3 that is polymerized inside the non-woven fabric mask member 2 and the cotton mask member 4 that is polymerized inside the chemical fiber mask member 3 are laminated in four layers, and each mask member 1 to 4 are integrally formed by sewing, for example, by sewing together the peripheral edges of the four.
[0032]
The 1st nonwoven fabric mask member 1 is formed in the rectangular shape with the nonwoven fabric coarser than the 2nd nonwoven fabric mask member 2 mentioned later. Thus, since the 1st nonwoven fabric mask member 1 is comprised with the nonwoven fabric and this is arrange | positioned on the outermost side, viruses (henceforth a "virus" only), such as SARS virus, are for 1st nonwoven fabric masks. By adsorbing on the surface of the member 1, it is possible to prevent the virus from entering the multilayer mask A as much as possible.
[0033]
The second nonwoven fabric mask member 2 is formed in a rectangular shape by a finer nonwoven fabric (for example, a high-density nonwoven fabric subjected to antibacterial processing used for medical use) than the first nonwoven fabric mask member 1. ing. Thus, since the 2nd nonwoven fabric mask member 2 was comprised with the fine nonwoven fabric, and this was arrange | positioned in the 2nd layer from the outer side, it was not able to interrupt | block with the above-mentioned 1st nonwoven fabric mask member 1. It is possible to reliably block the virus and reliably prevent the virus from entering the multilayer mask A.
[0034]
The synthetic fiber mask member 3 is formed in a rectangular shape by a chemical fiber such as polyester capable of charging static electricity. In this way, the chemical fiber mask member 3 is constituted by the chemical fiber having charging properties, and this is arranged in the third layer from the outside, so that the virus that has passed through each of the nonwoven fabric mask members 1 and 2 should be It can adsorb | suck to the surface of the member 3 for chemical fiber masks, and can prevent reliably that a virus will enter into the multilayer mask A inside.
[0035]
The cotton mask member 4 is formed in a rectangular shape with cotton fabric, and is disposed on the innermost side. Therefore, the cotton fabric mask member 4 absorbs moisture from the outside due to the characteristics of the cotton fabric, and removes moisture from the mouth of the user H. Can be adsorbed. In addition, since the cotton mask member 4 made of cotton is used at a position in direct contact with the skin of the user H, the feeling of use is improved and allergies to the skin of the user H can be prevented.
[0036]
Thus, since each mask member 1-4 is laminated | stacked and comprised, it can prevent reliably that a virus will enter into the multilayer mask A by each mask member 1-4. Can do.
[0037]
Also, a strip-shaped metal foil 5 extending in the left-right direction is attached in the vicinity of the upper end of the inner surface of the innermost mask member (here, the cotton mask member 4).
[0038]
The metal foil 5 is formed of a plastic material, and when the multilayer mask A is mounted, the metal foil 5 is deformed into a shape desired by the user H, so that the shape of the mask body M is changed to the metal foil 5. The user can be deformed along the desired shape of the user H, for example, along the face shape of the user H. Thus, when the metal foil 5 is deformed along the face shape of the user H when the multilayer mask A is worn, the mask body M can be worn while being in close contact with the user H. A virus can be prevented from entering.
[0039]
Alternatively, the breathing of the user H can be facilitated by deforming the metal foil 5 so that a gap is formed between the mask body M and the face of the user H.
[0040]
In this way, by deforming the metal foil 5, the mask body M can be freely deformed into a desired shape according to the application.
[0041]
Also, as shown in FIG. 2, between the mask member (here, the synthetic fiber mask member 3) arranged in the third layer from the outside and the mask member (here, the cotton mask member 4) arranged on the innermost side. In addition, by providing a translucent eye protector 6 that covers the eyes of the user H, it is possible to prevent the virus from being scattered and received on the mucous membrane of the eye while ensuring the vision of the user H. it can. The eye protector 6 may be formed by appropriately forming a transparent film-like material, and can be sewn simultaneously when each mask member is sewn.
[0042]
In this embodiment, the head straps B made of rubber or the like are attached to the upper and lower ends of the innermost mask member (here, the cotton mask member 4), respectively. H can be worn so that the multilayer mask A covers the head. In addition, the attachment method, attachment position, etc. of this head strap B can be determined as appropriate.
[0043]
The multilayer mask A according to the present invention has the above-described configuration, and can effectively prevent invasion of viruses scattered in the air into the body.
[0044]
That is, most of the virus is adsorbed by the first nonwoven fabric mask member 1, the amount of virus adsorption on the inner layer side is reduced, and the second nonwoven fabric mask member 2 reliably blocks the virus. In the unlikely event, the virus that has passed through the nonwoven fabric mask members 1 and 2 is surely blocked by the synthetic fiber mask member 3 charged with static electricity. Furthermore, the cotton mask member 4 reliably blocks moisture from the outside and adsorbs moisture from the mouth of the user H to prevent the mask from deteriorating.
[0045]
Further, the eye protector 6 that covers the eyes of the user H prevents the virus from adhering to the mucous membrane of the eye and infects it, thereby providing a more reliable infection prevention measure.
[0046]
At this time, the mask body M can be deformed and attached so as to be in close contact with the nose of the user H by the plastic metal foil 5. In this way, it is possible to prevent a gap from being formed between the user H and the multi-layer mask A, thereby preventing a virus from entering the user H's body.
[0047]
The metal foil 5 can be appropriately deformed so that the mask main body M is not in close contact with the nose of the user H to facilitate the breathing of the user H.
[0048]
In this way, the mask main body M configured in a four-layered state with the mask members 1 to 4 completely prevents the virus from entering the body of the user H.
[0049]
(Example 2)
A shown in FIG. 4 is a multilayer mask in the second embodiment, and the basic configuration is substantially the same as the multilayer mask A in the first embodiment, but differs in the configuration of the mask body M laminated in four layers. Hereinafter, detailed description will be given with reference to the drawings.
[0050]
The mask body M of the multilayer mask A in Example 2 includes a synthetic fiber mask member 3, a first nonwoven fabric mask member 1 that is polymerized on the inside (user H side) of the synthetic fiber mask member 3, and the same A cotton cloth mask member 4 made of gauze that is polymerized on the inside of one nonwoven fabric mask member 1 and a second nonwoven fabric mask member 2 that is polymerized on the inside of the cotton cloth mask member 4 are laminated in four layers. In addition, the mask members 1 to 4 are integrally formed by sewing, for example, by sewing together the peripheral edges of the mask members 1 to 4.
[0051]
The synthetic fiber mask member 3 is formed in a rectangular shape by a chemical fiber such as polyester capable of charging static electricity. As described above, the chemical fiber mask member 1 is constituted by the chemical fiber having charging properties, and this is disposed on the outermost side. Therefore, the virus is adsorbed on the surface of the chemical fiber mask member 1 so that the virus is absorbed into the multilayer mask A. It is possible to prevent entering the inside as much as possible.
[0052]
The 1st nonwoven fabric mask member 1 is formed in the rectangular shape with the nonwoven fabric coarser than the 2nd nonwoven fabric mask member 2 mentioned later. Thus, since the 1st nonwoven fabric mask 1 is comprised with the nonwoven fabric and this is arrange | positioned in the 2nd layer from the outside, a virus is made to adsorb | suck to the surface of the member 1 for 1st nonwoven fabric masks, and a virus is a multilayer type. It is possible to prevent the inside of the mask A as much as possible.
[0053]
Since the cotton mask member 4 is formed in a rectangular shape by gauze and is arranged in the third layer from the outside, the aerosol (fine dust) to which moisture and viruses from the outside adhere due to the characteristics of the gauze. By adhering to the surface of the cotton mask member 4, it is possible to block the entry into the human body as much as possible.
[0054]
The second nonwoven fabric mask member 2 is formed in a rectangular shape with a finer nonwoven fabric than the first nonwoven fabric mask member 4 (for example, a high-density nonwoven fabric subjected to antibacterial processing used for medical purposes). ing. Thus, since the 2nd nonwoven fabric mask member 2 is comprised with the fine nonwoven fabric, and this is arrange | positioned in the innermost side, the virus which could not be interrupted | blocked by each said mask members 1-3 is completely interrupted | blocked can do.
[0055]
Thus, in order to make use of the respective functions, the plurality of mask members 1 to 4 in the attached state, the synthetic fiber mask member 3 from the outside, the first nonwoven fabric mask member 1 having a relatively coarse mesh, and the cotton cloth The mask member 4 and the relatively fine second nonwoven fabric mask member 2 are laminated in this order.
[0056]
According to this configuration, the amount of the virus that is first adsorbed on the surface of the mask body M by the charged synthetic fiber mask member 3 and absorbed on the lower layer side is reduced as much as possible, and the first nonwoven fabric mask member 1 uses the virus. Adsorbs most of the amount of virus, further reducing the amount of virus adsorbed on the lower layer side. Then, the cotton cloth member 4 reliably blocks the aerosol (fine dust) to which moisture and viruses from the outside are attached. Furthermore, the fine second nonwoven fabric mask member 2 can reliably adsorb the virus reaching the lowest layer and reliably prevent entry into the human body.
[0057]
In the figure, the same reference numerals are given to the portions corresponding to the portions shown in the first embodiment, and the description thereof is omitted.
[0058]
The multilayer mask A according to the second embodiment is configured as described above. Also in this embodiment, it is possible to effectively prevent the virus that is scattered in the air from entering the body.
[0059]
That is, the amount of virus adsorbed on the surface of the mask body M by the charged synthetic fiber mask member 3 and absorbed on the lower layer side is reduced as much as possible, and the first nonwoven fabric mask member 1 adsorbs most of the virus. This further reduces the amount of virus adsorbed on the lower layer side. Then, the cotton cloth member 4 reliably blocks the aerosol (fine dust) to which moisture and viruses from the outside are attached. Furthermore, the fine non-woven second non-woven fabric mask member 2 reliably adsorbs the virus reaching the lowest layer and reliably prevents entry into the human body.
[0060]
In addition, the eye protector 6 that covers the eyes of the user H can prevent the virus from adhering to the mucous membrane of the eye and infect it, thereby providing more reliable infection prevention measures.
[0061]
At this time, if the mask body M is deformed and attached so as to be in close contact with the nose of the user H with the plastic metal foil 5, a gap is created between the user H and the multilayer mask A. To prevent the virus from entering the user H's body.
[0062]
The metal foil 5 may be appropriately deformed so that the mask body M is deformed so as not to be in close contact with the nose of the user H, thereby facilitating the breathing of the user H.
[0063]
In this way, the mask main body M configured in a four-layered state with the mask members 1 to 4 completely prevents the virus from entering the body of the user H.
[0064]
(1) In the present invention described in claim 1, the amount of the synthetic fiber mask member provided on the uppermost layer side (outermost side) is adsorbed on the surface of the mask body and absorbed on the lower layer side (inner side). Next, the amount of virus adsorbed on the lower layer side is further reduced by adsorbing most of the virus with the first non-woven fabric mask member, and then the moisture from the outside by the cotton mask member. And the aerosol (fine dust) attached to the virus is surely blocked, and the finer second non-woven mask member provided on the lowermost layer side securely adsorbs the virus reaching the lowermost layer to the human body. It is possible to reliably prevent the intrusion into. In particular, among the multiple layer mask members, since the strip-shaped metal foil is attached in the vicinity of the upper end of the inner surface of the second non-woven fabric mask member arranged on the innermost side, and when attached to the other layer mask member In comparison, when the metal foil is deformed along the shape of the face of the user, a gap is not easily formed between the face and the mask, and the virus is prevented from entering the mask as much as possible. It is possible to prevent the virus from entering the body. Moreover, since the mask member disposed in the lowermost layer is made of non-woven fabric, there is no sag unlike cotton fabric or gauze fabric, and the metal foil can be securely attached to the desired position, and the fabric after the attachment. Since there is no sagging, the fit between the metal foil and the face shape is not impaired. In addition, among the multiple mask members, the fiber mask member, which is placed on the outermost side and is in direct contact with the outside air, is made of charged chemical fibers, so that most of the virus is adsorbed on the surface of the fiber mask member. It is possible to prevent the virus from entering the multilayer mask as much as possible. In addition, since a translucent eye protector that covers the user's eyes is attached to one of the mask members, it is possible to prevent the virus from adhering to the mucous membrane of the eye and infecting it. can do.
