The microphone cover 21 is formed to have the same size as or slightly smaller than the microphone M so as to be mountable on the microphone M in a state in which the linear elastic body 5 is extended, and can further improve the suitability for the microphone M when mounted. In addition, since the microphone cover 21 has a plurality of fine wrinkles formed on the surface thereof by contracting the linear elastic body 5, when the microphone cover 21 is mounted on the microphone M, it is possible to prevent wind generated during the sound emission and respiration of the user from directly flowing into the sound pickup portion M1, and to remove noise included in the sound by the wrinkles of the microphone cover 21, thereby improving sound quality and picking up a softer and cleaner sound.
The microphone cover 21 is formed in a bag shape by folding and overlapping sheets having a shape as shown in fig. 2, for example, and joining the peripheral edges of the overlapped portions so as to form the mouth portion 22 to form a joint portion 26. The joining portion 26 can be joined by any conventionally known method such as ultrasonic joining, high-frequency joining, low-frequency joining, joining by heat sealing, joining by heat fusion, and joining by various adhesives such as hot melt adhesives. The bonding width of the bonding portion 26 may be determined arbitrarily, and is preferably a bonding width that does not cause breakage of the bonding portion 26 due to a force applied when the microphone M is mounted. The hole 29 can be formed as a non-joined portion when joining the long sides of the folded body. Furthermore, the folded end 24 may be similarly engaged with the other end. Further, the sheet is not limited to the case where one sheet is folded and joined into a bag shape, and two sheets may be overlapped and joined into a bag shape. In addition, when the microphone cover 21 in the state shown in fig. 2 is turned upside down, the joint portion 26 is located inside the bag shape, and the joint portion 26 cannot be visually confirmed, which is preferable.

The nonwoven fabric is defined as a nonwoven fabric in JIS L0222 as a product in which "fibers are oriented in one direction or randomly and are bonded to each other by crossing and/or fusing and/or bonding. However, paper, fabric, knits, tufted and shrink felts are excluded. "for example, a spunbonded nonwoven fabric, a chemically bonded nonwoven fabric, an air-laid (airlad) nonwoven fabric, a needle-punched nonwoven fabric, a spunlaced nonwoven fabric, a heat-sealed nonwoven fabric, a pulp air-laid nonwoven fabric, a nanofiber nonwoven fabric, etc., can be mentioned, and a meltblown nonwoven fabric can also be used, but the fiber sheet of the present invention can exhibit an excellent filtering function without using an expensive material having a high filtering function such as a meltblown nonwoven fabric, and thus a relatively inexpensive spunbonded nonwoven fabric is generally used. As the nonwoven fabric sheet, a material composed of fibers mainly composed of non-pulp fibers such as synthetic fibers is used. The amount of the non-pulp fibers contained in the nonwoven fabric sheet is preferably 50 mass% or more, more preferably 70 mass% or more, and still more preferably 80 mass% or more. Examples of the non-pulp fibers include natural fibers such as wool, silk, and cotton, polyester fibers such as nylon, vinylon, and polyethylene terephthalate, polyolefins such as polypropylene, polyethylene, and polypropylene, synthetic fibers such as polyurethane, regenerated fibers such as rayon, and semi-synthetic fibers such as acetate.
As the nonwoven fabric constituting the nonwoven fabric sheet, a meltblown nonwoven fabric, a spunbond nonwoven fabric, a spunlace nonwoven fabric, a heat-seal nonwoven fabric, a pulp air-laid nonwoven fabric, a nanofiber nonwoven fabric, or the like can be used. Examples of the knitted fabric include knit Stitch (media Stitch), plain Stitch (garter Stitch), rib Stitch (rib Stitch), mesh Stitch (net Stitch), leno Stitch (lace Stitch), short Stitch (single Stitch), long Stitch (long Stitch), and jujube Stitch (Bobble). Examples of the woven fabric include a flat fabric such as oxford (oxford), a fine flat fabric (broadcloth), a sheet fabric (sheeting), a waterproof fabric (weather), a canvas (canvas), and a gauze (gauze), a twill (twill) such as a serge, a gabardine (gabardine), and a denim (denim), and a satin fabric (satin) called a satin. The nonwoven fabric sheets 7 and 8 may be used by stacking the same or different types of nonwoven fabric sheets (for example, by stacking a spunbond nonwoven fabric and a meltblown nonwoven fabric), and the nonwoven fabric sheets 7 and 8 may be made of different materials. The first nonwoven fabric sheet 7 and the second nonwoven fabric sheet 8 are preferably made of 8 to 30g/m basis weight2One or two of the materials are overlapped. In addition, the adhesive may be applied to a nonwoven fabricThe sheets 7 and 8 contain the antibacterial substance or have an antibacterial layer containing the antibacterial substance on the surface.
The first nonwoven fabric sheet 7, the first paper sheet 3, the elastomer layer 6 composed of the threadlike elastomer 5, the second paper sheet 4, and the second nonwoven fabric sheet 8 are joined and integrated via adhesive layers 9, 10, and 11. The adhesive for forming the adhesive layers 9, 10, and 11 is preferably a hot melt adhesive. Examples of the hot-melt adhesive include ethylene vinyl acetate, polyolefins, synthetic rubbers, polyamides, polyurethanes, and amorphous a-olefin copolymers. The hot melt adhesive is preferably supplied by spraying or the like in a planar manner to the surface of the paper sheet or the nonwoven fabric sheet, and the sheets are joined to each other. The threadlike elastic body 5 constituting the elastic body layer 6 is preferably bonded between the first paper sheet 3 and the second paper sheet 4 via a hot-melt adhesive applied to the surface of the threadlike elastic body 5.
When the paper sheet, the elastomer layer, and the nonwoven fabric sheet are bonded to each other with a hot melt adhesive or the like, if the sheets are bonded in a state in which the threadlike elastic body 5 is stretched, the threadlike elastic body 5 contracts due to the restoring force of the threadlike elastic body 5 when the stretched state is released, wrinkles are generated on the surfaces of the first paper sheet 3 and the second paper sheet 4 bonded to the threadlike elastic body 5 in association with the contraction of the threadlike elastic body 5, and wrinkles are also formed on the surfaces of the first nonwoven fabric sheet 7 and the second nonwoven fabric sheet 8 bonded to the first paper sheet 3 and the second paper sheet 4. As a result, the fiber sheet 1 as a whole is provided with stretchability in the longitudinal direction of the linear elastic body 5, and fine uneven wrinkles are formed on the surface of the fiber sheet 1, thereby providing stretchability to the fiber sheet 1.
The fiber sheet may sandwich the moisture absorbent between the first paper sheet 3 and the second paper sheet 4. When the moisture absorbent is disposed between the paper sheets 3 and 4, for example, droplets, sweat, and the like are absorbed and held by the moisture absorbent, so that uncomfortable moist feeling during use can be reduced, and moisture retention can be improved. Examples of the moisture absorbent include Super Absorbent Polymers (SAP), super absorbent polymer fibers (SAF), silica gel desiccants, magnesium chloride-based moisture absorbents (dremax (trade name)), magnesium chloride-based moisture absorbents (KALAHARI DRY (trade name), EX-DRY (trade name), and the like), natural zeolites, synthetic zeolites, silica-alumina-based moisture absorbents such as montmorillonite and allophane, clay-based moisture absorbents such as bentonite and clay, and the like.
Fig. 4 shows another form of the fiber sheet 1 used for the sanitary cover of the present invention. The fiber sheet 1 has a structure in which a nonwoven fabric sheet is provided only on the surface side of one of the first paper sheet 3 and the second paper sheet 4. The fiber sheet 1 in this form is formed by bonding the coat layer 2 side of the first paper sheet 3 provided with the coat layer 2 and the coat layer 2 side of the second paper sheet 4 provided with the coat layer 2 between the coat layer 2 sides via an adhesive layer 10 formed by a hot melt adhesive or the like, and bonding the nonwoven fabric sheet 7 to the front surface side of the first paper sheet 3 via an adhesive layer 9 formed by a hot melt adhesive or the like. In the case of the fiber sheet 1 of this form, it is preferable that the paper sheet 3 to which at least one side of the nonwoven fabric sheet 7 is joined has a coating layer 2 formed on one side or both sides.
The fiber sheet 1 may be subjected to softening treatment by embossing or the like, if necessary. The embossing can be performed by pressing both sides of the fiber sheet 1 with embossing rolls, but the embossing can also be performed by pressing the fiber sheet 1 between embossing rolls and flat rolls. The embossing roll may have a plurality of irregularities on the surface, or may have a stripe of irregularities in the longitudinal direction of the web 1 (longitudinal embossing roll) or in the width direction of the web 1 (transverse embossing roll), or may be a combination of these rolls to perform the irregular embossing. In addition, the fiber sheet of the first embodiment and the fiber sheet of the second embodiment may be further laminated with a woven fabric, a knitted fabric, or the like on at least one surface.
Next, the operation and effect of the sanitary cover of the present invention will be described.
The sanitary cover of the utility model is composed of a laminated sheet formed by laminating a non-woven fabric sheet on a composite sheet, the composite sheet is formed by arranging and bonding an elastic body layer 6 between paper sheets having a coating agent coating layer 2 on at least one surface, the laminated sheet is formed by bonding the sheets with a hot-melt adhesive applied in a planar manner so as to be stretchable, the fiber sheet is formed by bonding the sheets with a hot melt adhesive coated in a planar manner so as to be stretchable, the fiber sheet is excellent in the permeation prevention performance of fine particles, and therefore, when a microphone or the like is covered with the sanitary cover of the present invention, the surface area of the microphone cover 21 is increased by forming the wrinkles while maintaining the sound-collecting performance of the microphone, this prevents droplets scattered from the mouth of the user and dirt on the hand from adhering to the microphone and the like. Further, the risk of contamination of the next user with droplets scattered from the mouth of the previously used person, dirt on the hands, sweat, and the like can be reduced. Further, the fibrous sheet constituting the sanitary cover of the present invention has a structure in which the paper sheet and the nonwoven fabric sheet are laminated, and therefore, the sanitary cover is excellent in moisture absorption and air permeability, and is sanitary because the risk of the user that sweat, saliva, and the like adhere to the surface is reduced, and the uncomfortable feeling of use due to sweat and the like adhering to the surface can also be reduced. Further, since the fibrous sheet has elasticity, the fibrous sheet is excellent in suitability for the object to be mounted.
As described above, according to the sanitary cover of the present invention, the dustproof property and the flying defense property can be improved, and the sanitary cover can be used while maintaining the sanitary state, and the possibility that the risk of viral infection and the like, which have been a serious problem in recent years, can be reduced can be improved. In addition, since the microphone cover 21 has a plurality of fine wrinkles formed on the surface thereof by contracting the linear elastic body 5, when the microphone cover 21 is mounted on the microphone M, it is possible to prevent wind generated during the sound emission and respiration of the user from directly flowing into the sound pickup portion M1, and to remove noise included in the sound by the wrinkles of the microphone cover 21, thereby improving sound quality and picking up a softer and cleaner sound.
Next, another embodiment of the sanitary cover of the present invention will be described. The same description as above is omitted for the configuration and operational effects of the sanitary cover. Fig. 5 shows a state in which the microphone cover 21 as the sanitary cover is viewed from the front, and fig. 6 shows a state in which the microphone cover 21 is turned upside down. The microphone cover 21 shown in fig. 5 and 6 is formed so as to be able to be mounted only on the sound pickup portion M1 of the microphone M. Since the microphone cover 21 can cover the sound pickup portion M1, which is often close to the mouth of a person during use and in which droplets are particularly likely to adhere and invade, according to this embodiment, the microphone cover can be used while maintaining the above-described sanitary state, and the above-described risk of the user can be reduced. In the case of the microphone cover 21 of this embodiment, both end edges of the folded portion 24 are cut off, and the cut-off edge portions are also joined, whereby the microphone cover 21 and the microphone can be formed into shapes suitable for the shape when the microphone M is mounted. When the microphone cover 21 is turned upside down in the state shown in fig. 6, the microphone cover 21 shown in fig. 5 is obtained.
As shown in fig. 7 to 9, the microphone cover 31 may be configured such that a grip 32 is formed at an end portion on the side where the microphone M is mounted to the sound pickup unit M1, and the microphone cover is mounted to the sound pickup unit M1 by being gripped by the grip 32 or removed from the sound pickup unit M1 after use. In this way, by forming the grip portion 32, the part of the microphone cover 31 to which the mist is easily attached can be removed without being in contact with the part, and thus the risk of infection with viruses or bacteria can be reduced. The grip portion 32 may be formed at only one location, or may be formed at two or more locations. For example, in the case of two-point formation, if the respective nipping portions 32 are formed at positions facing each other, the sound receiving portion M1 can be easily attached and detached. The microphone cover 31 is formed in a bag shape with a curved upper portion as shown in fig. 8. When the microphone cover 31 is turned upside down as shown in fig. 9, the joint portion 26 is formed at the periphery other than the mouth portion. By forming the microphone cover 31 in this way, the microphone M can be more easily fitted when the microphone M is mounted.

As the nonwoven fabric constituting the sheet, a nonwoven fabric having a basis weight of 10g/m was used2The spunbonded nonwoven fabric of (2) used as a paper sheet and having a basis weight of 13g/m2The paper for paper towels of (1). The linear elastic bodies are arranged between the paper sheets at a pitch of 5mm, and the nonwoven fabric sheet and the linear elastic bodies are arrangedBetween paper sheets, at a ratio of 7g/m2Applying a hot melt adhesive in a planar form and bonding the sheets together at a ratio of 11g/m2The hot melt adhesive is applied in a planar form and joined. The paper sheet used was one-side coated with a base weight of 1.8g/m2A material coated with an acrylic coating agent to provide a coating layer. The threadlike elastic body is sandwiched between the paper sheets in a stretched state and joins the sheets to each other. The following sheets were set: when the stretched state of the threadlike elastic body is released, the threadlike elastic body contracts in the longitudinal direction by 1/2.5 to form a plurality of wrinkles on the surface. The sheet was used as a test sample to test the microparticle-capturing property and the ultrafine particle-capturing property.
Test method
As the fine particles for the test, use was made of Lycopodium clavatum (30 to 40 μm) manufactured by Nippon powder Industrial technology Association, use was made of MAGSPHERE PSL standard particles having a particle size of 0.1 μm as ultrafine particles, and the sample area was 100cm under the conditions of a temperature of 23 ℃. + -. 2.0 ℃ and a relative humidity of 40. + -. 10%2The test particles were supplied at 58L/min, and the trapping rate of the test particles was determined. The collection rate of microparticles was determined by measuring the weight of the sample and the collection filter on the downstream side of the sample using an electronic scale (model: CP225D) manufactured by Sartorius. The ultrafine particle collection ratio was measured using a scanning mobility particle size meter manufactured by TSI: the SMPS (model: 3938) measures the particle concentration on the upstream side and the downstream side of the sample to determine the collection rate. The results of the microparticle capture rate are shown in table 1, and the results of the ultrafine particle capture rate are shown in table 2.
TABLE 1
Microparticle trapping ratio (%)
Test 1 99.0
Test 2 99.5
Test 3 99.3
Average 99.3

Capture rate of ultrafine particles (%)
Test 1 79.5
Test 2 81.0
Test 3 79.3
Test 4 78.6
Test 5 83.1
Average 80.3
From these results, it can be understood that: the sheet constituting the sanitary cover of the present invention has excellent trapping properties particularly for microparticles of about 30 to 40 μm and also for ultrafine particles of about 0.1 μm. Therefore, the microphone cover 21 configured by using the sheet can stop the scattered matter such as the mist scattered from the mouth of the user or the like on the surface or inside the sheet, and can prevent the scattered matter from entering the inside of the microphone M and becoming unsanitary.
The sanitary cover according to the present invention has been described in detail, but the above description is merely an example of the sanitary cover according to the present invention, and modifications can be made without departing from the scope of the present invention. For example, in the sanitary cover, the width of the mouth portion 22 may be formed wider than the width of the other portions, and the portion where the mouth portion 22 is formed may be folded back to form a layer having a plurality of layers, thereby improving the strength around the mouth portion 22. When the sanitary cover of the present invention is applied to a glove, the paper sheets 3 and 4 can easily absorb sweat from the hand, and the presence of the nonwoven fabric sheets 7 and 8 can provide a glove with good hand feeling and excellent air permeability for the wearer. Other modifications may be made as appropriate.
