JP5060702B2 - Face mask nose clip and face mask - Google Patents

Description

  The present invention relates to a face mask nose clip and a face mask that use a shape-retaining material that is excellent in retaining the deformed shape when deformed.

  Conventionally, various facial masks used for medical and hygiene applications include a mask body that covers the mouth, nose, etc., with a nose clip attached to the outer surface of the nose. Exists. The nose clip has a function of causing the mask to follow the uneven shape of the nose when the face mask is worn, and is also referred to as a nose wire or a nose bridge.

  Conventionally, as a face mask provided with a nose clip, in a mask body made of nonwoven fabric and gauze (hereinafter abbreviated as nonwoven fabric etc.), the nose clip is sealed inside by bonding a pair of nonwoven fabric etc. A pleat type face mask or a dust-proof type face mask in which a nose clip is bonded to a non-woven fabric or the like formed in a cup shape is often used.

  The nose clip is required to have a function of retaining the deformed shape while being deformable according to the shape of the nose even when the shape of the nose is different. Therefore, conventionally, the nose clip has been made of a metal material having excellent plastic deformability. For example, Patent Document 1 below discloses a metal nose clip made of aluminum.

  However, when the waste is separated and discarded, the metal nose clip must be separated and discarded from the mask body made of a nonwoven fabric or the like. Therefore, the separation work is complicated. In addition, the metal nose clip may cause damage to the skin surface of the nose and may cause metal allergy, which is difficult in terms of safety.

  Therefore, there is a demand for a nose clip made of a resin such as a plastic instead of a metal.

  However, in general, when a nose clip made of resin is configured, even if it is deformed along the face shape, it easily returns to the original shape. That is, it has been difficult to achieve sufficient shape retention.

  On the other hand, Patent Document 2 below discloses a face mask having a nose clip made of a synthetic resin. Here, the nose clip is made of a shape retaining material made of resin. More specifically, a first component to which an inorganic filler such as glass fiber, talc, mica and calcium carbonate is added in order to impart plastic deformation to polyethylene having an intrinsic viscosity of less than 3.5 dl / g, and a first component It is said that a shape-retaining material having excellent shape-retaining properties can be obtained by co-extrusion of a second component comprising a polymer that is heat-sealed with polyethylene.

  However, in the nose clip described in this prior art, by mixing an inorganic filler such as glass fiber or calcium carbonate with a resin such as polyethylene as described above, and coextruding the second component together with the first component, Shape retention is obtained by utilizing the characteristics of the two-component resin. Therefore, in the production, an inorganic filler such as calcium carbonate or glass fiber has to be added to the resin, and the production is complicated.

  Moreover, since shape retention was obtained by mix | blending inorganic fillers, such as glass fiber and a calcium carbonate, with resin, it was difficult to reuse resin after disposal.

  In addition, the nose clip made of resin tends to have insufficient adhesion between the mask body and the nose clip when bonded to the mask body made of nonwoven fabric or the like.

Patent Document 3 below discloses a polyolefin string in which a sheet having a three-dimensional polyolefin having a weight average molecular weight of 500,000 or less is rolled and then stretched to have a total draw ratio of 10 times or more. Here, it is stated that when the total draw ratio, which is the product of the rolling ratio and the draw ratio, is 10 times or more, it can be easily twisted and bound by hand. The rolling ratio is preferably 2 to 10 times, and then stretched about 3 times. In that case, when the thickness of the string to be obtained is thick, when cutting the stretched sheet to form a string, whiskers may occur on the cut surface, or rattling may occur. It was difficult to obtain a thick string.

  In view of the current state of the prior art described above, an object of the present invention is made of a resin, has sufficient shape retaining ability to hold a deformed shape, is easy to discard, and can be reused after disposal. It is an object of the present invention to provide a face mask nose clip and a face mask using a shape-retaining material that is easy to manufacture and has excellent productivity.

According to a wide aspect of the present invention, a thermoplastic resin film is formed on a strip made of a stretched polyolefin resin having a rolling ratio of 5 to 16 times, a stretching ratio of 1.3 to 2.5 times, and a total stretching ratio of 10 to 40 times. It is made of laminated shape-retaining material, and its shape-retaining angle (the shape-retaining material is bent at a right angle along the mold, then the force is released and the inner angle of the shape-retaining material is released) There is provided a nose clip for a facial mask characterized by being no greater than 99 degrees .

  The face mask according to the present invention comprises a mask body and a nose clip for a face mask provided on the mask body and configured in accordance with the present invention so that the face mask contacts the face when the nose clip is attached. It is configured.

  On the specific situation with the facial mask which concerns on this invention, the said mask main body is comprised with the nonwoven fabric.

  In another specific aspect of the facial mask according to the present invention, a nose clip for a facial mask constructed according to the present invention is bonded to a mask body made of a nonwoven fabric with a hot melt adhesive.

  In still another specific aspect of the facial mask according to the present invention, a part of the face mask nose clip configured according to the present invention is bonded to the mask body by ultrasonic fusion.

  Details of the present invention will be described below.

  When the total draw ratio of the stretched olefin-based resin sheet in the present invention is small, the shape retention may be insufficient, and when it is large, it may be liable to tear longitudinally, so that it is 10 to 40 times, preferably 15 to 35 times.

  In addition, although the shape retention material which concerns on this invention is equipped with the strip | belt material which consists of the said extending | stretching olefin resin sheet at least, this strip | belt material is obtained by rolling and extending | stretching an olefin resin. The total draw ratio is the product of the rolling ratio and the draw ratio. The roll ratio is 5 to 16 times, the draw ratio is 1.3 to 2.5 times, and the total draw ratio is 10 to 40. Doubled.

  As the olefin-based resin constituting the stretched olefin-based resin sheet, any olefin-based resin having a film forming ability can be used. For example, a high-density polyethylene resin, a medium-density polyethylene resin, a low-density polyethylene resin, a linear low-density Polyethylene resin, polypropylene resin, ethylene-propylene copolymer, ethylene-pentene-1 copolymer, ethylene-vinyl acetate copolymer, ethylene- (meth) acrylate copolymer, ethylene-vinyl chloride copolymer, Examples thereof include an ethylene-propylene-butene copolymer, and a high-density polyethylene resin is preferably used.

When the density of the high-density polyethylene resin is reduced, the shape retention is not improved even when stretched, so 0.94 g / cm ³ or more is preferable.

  In addition, if the weight average molecular weight of the high-density polyethylene resin is too small, the shape-retaining property is not so much improved even if it is stretched, and if it is too large, it becomes difficult to form and stretch the film. preferable. The melt index (MI) is preferably in the range of 0.1 to 20 where the film formability is excellent, more preferably 0.2 to 10.

  In the present invention, the high-density polyethylene may be used alone, but other polyolefins may be mixed in a proportion of 30 parts by weight or less with respect to 100 parts by weight of the high-density polyethylene. Examples of other polyolefins used in combination include low density polyethylene, ethylene-vinyl acetate copolymer, and polyvinyl acetate. Further, the high-density polyethylene may be cross-linked.

  The rolling is a method in which an olefin-based resin sheet is supplied to a pair of rolls rotating in opposite directions and pressed to reduce the thickness of the sheet and to elongate.

  If the rolling temperature is low, rolling may not be performed uniformly, and if it is high, melt cutting may occur. Therefore, the roll temperature at the time of rolling is "melting point -40 ° C" of the olefin resin of the olefin resin sheet to be rolled. The melting point is preferably in the range of “melting point −30 ° C.” to “melting point −5 ° C.” of the olefin resin.

  In the present invention, the melting point refers to the maximum point of the endothermic peak that accompanies melting of the crystal, which is recognized when thermal analysis is performed with a differential scanning calorimeter (DSC).

If the rolling ratio is small, the subsequent stretching is burdened, and if it is too large, the subsequent stretching becomes difficult, so it is limited to 5 to 16 times. If the rolling ratio is too small, not only a sheet having a high total stretching ratio cannot be obtained, but local stretching occurs in the next stretching step, and uniform stretching becomes difficult. Furthermore, the thickness of the sheet after stretching differs in the width direction, and those having the same shape retention performance cannot be obtained. Moreover, it is difficult to efficiently perform rolling 16 times or more with a normal rolling method. In the present invention,
Rolling ratio = (cross-sectional area of the sheet before rolling) / (cross-sectional area of the sheet after rolling)
Stretch ratio = (cross-sectional area of the sheet before stretching) / (cross-sectional area of the sheet after stretching)
Total stretch ratio = (cross-sectional area of the sheet before rolling) / (cross-sectional area of the sheet after stretching)
It is.

  The stretching performed after the rolling may be any conventionally known method, and examples thereof include a method of stretching while heating with a heater or hot air by a roll stretching method or a zone stretching method.

  If the stretching temperature is low, the film may not be uniformly stretched, and if it is high, the sheet may be melt-cut. Therefore, the stretching temperature is from “melting point −60 ° C.” to melting point of the olefin resin of the olefin resin sheet to be stretched. The range is preferably “melting point−50 ° C.” to “melting point−5 ° C.” of the olefin resin.

  The stretching ratio after rolling may be determined by considering the total rolling ratio in consideration of the rolling ratio, but if the stretching after rolling is small, the shape retaining property required for the nose clip cannot be obtained, but cannot be obtained. It is preferably 1.3 times or more, more preferably 1.5 times or more. Further, if the draw ratio is too high, whiskering or rattling occurs at the end when the nose clip is cut out from the sheet, the draw ratio is 2.5 times or less.

  The stretched olefin-based resin sheet has a reduced shape retention force when it is thinned, and the shape tends to be restored following the mask body, and when it is thick, it becomes difficult to form a desired shape. The thickness is generally 0.05 to 1.5 mm, preferably 0.15 to 1.0 mm.

  However, the thickness and width of the nose clip may be appropriately set according to the face mask to which the nose clip is applied so as to exhibit an excellent wearing feeling. For example, in the nose clip used for the pleated type face mask described above, it is preferable that the nose clip has a thickness of 0.15 to 0.9 mm and a width of 2 to 10 mm. On the other hand, in a nose clip used for a dust-proof face mask in which a nonwoven fabric or the like is formed in a cup shape, the nose clip preferably has a thickness of 0.3 to 1.2 mm and a width of 3 to 16 mm.

  The bending rigidity is a physical property proportional to the cross-sectional second moment (proportional to the square of thickness), but the shape retention force is a physical property that conforms to the bending rigidity of the shape-retaining material, and is therefore approximately proportional to the square of the thickness. Value.

Nose clip of the present invention, on at least one surface of the web made of the stretched olefin resin sheet, which thermoplastic resin film is laminated, that can prevent the cracking of the stretched olefin resin sheet, and, This is preferable in terms of adhesion to the mask body.

  The nose clip is composed of a laminated strip of stretched olefin resin sheet and nonwoven fabric, or a laminate strip of stretched olefin resin sheet, thermoplastic resin film, and nonwoven fabric laminated in this order. In this case as well, as described above, the adhesiveness to the mask body is easily improved, which is preferable.

  As the thermoplastic resin constituting the thermoplastic resin film, one that is firmly bonded to the stretched olefin resin sheet is preferable, and therefore, the above-mentioned olefin resin and ethylene vinyl acetate resin (EVA) can be suitably used.

  When the thermoplastic resin is a resin having a melting point lower than that of the olefin resin constituting the stretched olefin resin sheet and capable of adhering to the olefin resin, the thermoplastic resin is heated by an adhesive means such as heat fusion. When laminating a plastic resin film, it is preferable in that the stretched olefin resin sheet can be bonded without substantially heat shrinking. More preferably, the thermoplastic resin has a melting point 5 to 50 ° C. lower than the melting point of the olefin resin.

Therefore, when the olefin resin is a high density polyethylene resin, the thermoplastic resin is preferably a linear low density polyethylene resin, a low density polyethylene resin, or an ethylene-vinyl acetate copolymer (EVA).

  The thickness of the thermoplastic resin film is not particularly limited, but if it is too thick, the shape retaining property against deformation of the nose clip obtained is likely to be lowered, so that it is generally 0.01 to 0.3 mm, preferably 0.8. 02 to 0.1 mm.

  The thermoplastic film may be laminated on one side of the stretched olefin resin sheet, or may be laminated on both sides. Further, a plurality of the thermoplastic films and stretched olefin resin sheets may be used, and for example, a multilayer configuration in which layers are alternately laminated may be used.

The nonwoven fabric is not particularly limited as long as it is a cloth-like product made by bonding fibers without using a spinning machine, a loom, or a knitting machine. However, the stretched olefin resin sheet is laminated by heat fusion or the like. In terms of easyness, those made of thermoplastic resin fibers such as polyolefin and polyester are preferred. The basis weight of the nonwoven fabric preferably has a 10 to 300 g / m ^2, more preferably from 20 to 200 g / m ^2.

  When the thermoplastic resin constituting the non-woven fiber is a resin having a melting point lower than that of the olefin resin constituting the stretched olefin resin sheet and capable of adhering to the olefin resin, for example, heat fusion When the thermoplastic resin film is laminated by an adhesive means such as the above, it is preferable in that the stretched olefin-based resin sheet can be bonded without substantially thermal shrinkage. More preferably, the thermoplastic resin has a melting point 5 to 50 ° C. lower than the melting point of the olefin resin.

Accordingly, examples of the thermoplastic resin include polyethylene resin, polypropylene resin, ethylene-vinyl acetate copolymer (EVA), and when the olefin resin is a high-density polyethylene resin, the thermoplastic resin is linear. A low density polyethylene resin, a low density polyethylene resin or an ethylene-vinyl acetate copolymer (EVA) is preferred.

  The nonwoven fabric may be laminated on one side of a stretched olefin resin sheet or may be laminated on both sides. Moreover, the said nonwoven fabric and the extending | stretching olefin resin sheet are used in multiple numbers, for example, the multilayer structure laminated | stacked alternately may be sufficient.

  The face mask of the present invention (see FIGS. 1, 2, 4 and 5) is not particularly limited as long as it is provided on the mask body so as to come into contact with the adherend when the nose clip is attached, The nose clip may be used not only on the nose portion but also on all or part of the periphery of the mask.

  Moreover, it is preferable that the mask main body is made of a nonwoven fabric in that the adhesiveness with the nose clip is improved.

  In the face mask of the present invention, when the face mask nose clip is bonded to the mask body made of nonwoven fabric by a hot melt adhesive, the nose clip and the mask body can be firmly bonded. preferable.

  In the above, in the case where the nose clip for the face mask is composed of a laminated strip obtained by laminating the strip made of the stretched olefin resin and the nonwoven fabric, the nonwoven fabric of the mask body and the nonwoven fabric constituting the nose clip are hot-melted. It can adhere | attach via an adhesive agent, In this case, it becomes possible to adhere | attach a nose clip more firmly with a mask main body.

  The hot melt adhesive is not particularly limited, and conventionally known adhesives can be used. Examples of such hot melt adhesives include, for example, an ethylene-propylene copolymer system, a propylene-1-butene copolymer system, an ethylene-1-butene copolymer system, and a homopolypropylene copolymer mainly composed of amorphous polyolefin. Hot melt adhesion such as polymer systems, olefin copolymer systems such as EVA (ethylene-vinyl acetate copolymer) system, EVOH (ethylene-vinyl alcohol copolymer) system, EEA (ethylene-ethyl acrylate copolymer) system Agents.

  Further, the hot melt adhesive may contain other low molecular weight components such as other thermoplastic resins and waxes as necessary.

If the viscosity of the hot-melt adhesive is too low, the mechanical strength of the hot-melt adhesive itself is small, and the hot-melt adhesive may be excessively impregnated inside the nonwoven fabric, resulting in insufficient adhesive strength and too high. And the handleability of a hot melt adhesive tends to deteriorate. Therefore, in the case of using an ethylene-vinyl acetate copolymer -based hot melt adhesive, the viscosity is preferably 300 to 30,000 mP · s at the bonding temperature, more preferably 1,000 to 10,000. 000 mP · s.

  As an adhesion method in the above, for example, a hot melt adhesive heated using a hot melt gun or a hot melt applicator is applied to the nose clip, and the application surface is necessary for a nose portion in a nonwoven fabric of the mask body. A method of pasting so as to be in contact with the surface of the part is suitable.

The ultrasonic fusion may be performed at any part of the nose clip. However, by melting only both ends of the nose clip to the mask body, the nose clip retains almost no shape retention. Can be worn. The method of ultrasonic fusion is not particularly limited, but usually, vibration of 10 KHz or more is applied to the fusion part.
The face mask nose clip may be colored for the purpose of clearly indicating the position of the nose clip in the mask. The coloring can be performed by a method of adding a pigment to a stretched olefin resin sheet or a thermoplastic resin film.

Since the nose clip for a face mask of the present invention is a shape-retaining material in which a thermoplastic resin film is laminated on a belt-shaped object composed of a stretched olefin-based resin sheet having a total stretch ratio of 10 to 40 times, A nose clip suitable for a facial mask can be provided due to the property of maintaining a shape against deformation such as bending, which occurs in a highly stretched olefin resin.

  The generation mechanism of the shape retention is not necessarily clear, but the olefinic resin is highly stretched to increase the molecular strength in the stretching direction, and the elastic limit for tensile deformation is in the low strain region, resulting in bending deformation. Therefore, it is considered that since the amount of tensile deformation on the surface exceeds the elastic limit, plastic deformability and shape retention are exhibited.

In the face mask of the present invention, a nose clip made of a shape-retaining material formed by laminating a thermoplastic resin film on a strip made of the above-mentioned stretched olefin resin is used. With the hot melt adhesive, a facial mask firmly bonded to the mask body can be provided.

The nose clip for a face mask of the present invention has a thermoplastic resin film on a strip formed of a stretched polyolefin resin having a rolling ratio of 5 to 16 times, a stretching ratio of 1.3 to 2.5 times, and a total stretching ratio of 10 to 40 times. It is made of laminated shape-retaining material, and its shape-retaining angle (the shape-retaining material is bent at a right angle along the mold, then the force is released and the inner angle of the shape-retaining material is released) Since it is 99 degrees or less, it is possible to provide a nose clip that has a shape-retaining property suitable for a facial mask and has a low environmental impact when discarded.

Since the nose clip is formed by laminating a thermoplastic resin film on at least one side of the stretched olefin-based resin sheet, it can prevent cracking of the stretched olefin-based resin sheet and improve the adhesion to the mask body. it can.

  The facial mask of the present invention is characterized in that it is provided on the mask body so as to abut on the adherend when the nose clip is attached. Even if it is deformed, the shape is difficult to return to its original shape and has good shape retention.

  When the nose clip is bonded to the non-woven fabric of the mask body via a hot melt adhesive in the face mask, in addition to the above effects, a face mask having excellent adhesion between the nose clip and the mask body is provided. can do.
