Description

Technical Field

[0001] The present invention relates to an adhesive cleaner for capturing mites. Background Art

[0002] In the past, as a means of cleaning floors, carpets, etc., an adhesive cleaner having an adhesive tape was used. As an adhesive cleaner, the following adhesive cleaner is known: it has an adhesive tape, the adhesive tape has a strip-shaped base material and an adhesive surface formed only on one surface of the base material, and forms a winding body obtained by winding the adhesive tape with the adhesive surface facing outward. With the adhesive cleaner, by rolling the winding body on the cleaning object such as the floor, foreign matter on the cleaning object can be attached to the adhesive surface. In addition, in a case where the adhesive force of the adhesive surface is reduced due to the capture of foreign matter, etc., the outermost portion of the winding body that has been used can be disconnected to expose a new adhesive surface (for example, Patent Document 1).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-745 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] However, such conventional adhesive cleaners have a problem that even if they can temporarily capture walking pests such as house dust mites, the surviving mites move on the adhesive surface and escape from the adhesive surface.

[0008] In view of the above problems, an object of the present invention is to provide a sticky cleaner having an excellent performance in capturing mites.

[0009] Solutions for solving problems

[0010] The adhesive cleaning device for capturing mites according to the present invention comprises an adhesive tape,

[0011] The adhesive tape includes an adhesive portion having an adhesive surface, and is formed into a rolled body which is wound with the adhesive surface facing outward.

[0012] The wound body is configured to roll while the adhesive surface is in contact with the cleaning object.

[0013] The adhesive portion has a hardness of 0.005 MPa or more and 0.04 MPa or less.

[0014] The sticky cleaner having the above-described structure can sink mites into the sticky portion and capture them by setting the hardness of the sticky portion to 0.005 MPa or more and 0.04 MPa or less, and thus has excellent performance in capturing mites.

[0015] In the adhesive cleaner for capturing mites according to one embodiment of the present invention,

[0016] The adhesive tape comprises a surface layer portion including the adhesive portion,

[0017] The adhesive force of the surface layer is 25 N / 25 mm or less.

[0018] According to the above configuration, by making the adhesive force of the surface layer portion 25N / 25mm or less, the winding body can be easily rolled (improved running performance) even if the cleaning object is easy to stick to the adhesive surface, such as a floor or other cleaning object with a relatively smooth surface with few bumps. More specifically, it is possible to prevent the winding of the winding body from loosening and causing the adhesive tape to stick to the cleaning object (rail pulling phenomenon).

[0019] In the sticky cleaner for capturing mites according to one aspect of the present invention, the sticky part contains 50 parts by mass or more of a plasticizer based on 100 parts by mass of the polymer.

[0020] According to the above configuration, since the adhesive portion contains 50 parts by mass or more of the plasticizer based on 100 parts by mass of the polymer, the adhesive portion becomes soft and mites can easily sink into the adhesive portion.

[0021] In the sticky cleaner for capturing mites according to one aspect of the present invention, the thickness of the sticky portion is 20 μm or more and 150 μm or less.

[0022] According to the above configuration, by setting the thickness of the adhesive portion to be 20 μm or more, mites can be deeply sunk into the adhesive portion, thereby achieving better performance in capturing mites. In addition, by setting the thickness of the adhesive portion to be 150 μm or less, the viscosity of the adhesive portion can be appropriately suppressed, thereby suppressing the generation of residual adhesive due to a portion of the adhesive portion being transferred to the cleaning object.

[0023] Effects of the Invention

[0024] As described above, according to the present invention, it is possible to provide a sticky cleaner having an excellent performance in capturing mites. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Hereinafter, a sticky cleaner according to an embodiment of the present invention will be described with reference to the drawings.

[0034] like Figure 1 and Figure 2 As shown, the adhesive cleaner 1 of this embodiment comprises: a rod-shaped roller member 10 that can rotate around an axis, an adhesive tape 20 that is formed into a cylindrical winding body 20r in a manner of forming a through hole for penetrating the roller member 10, an axis member 30 that supports the roller member 10 in a manner that allows the roller member 10 to rotate around the axis, and a holding member 40 connected to the end of the axis member 30 on the opposite side of the portion supporting the roller member 10.

[0035] In the adhesive cleaner 1 of the present embodiment, the roller member 10 is cylindrical with an outer peripheral surface that supports the inner peripheral surface of the winding body 20r, and is configured to be rotatable around an axis while supporting the winding body 20r. The adhesive tape 20 includes a surface portion 21 having an adhesive surface that contacts the cleaning object, and the winding body 20r is formed by winding the adhesive surface toward the outside. The shaft member 30 is formed by bending a metal rod at a predetermined position. Specifically, the shaft member 30 includes: a roller support shaft that passes through the roller member 10, and an operating shaft 31 that extends from the roller support shaft to the outside of the roller member 10 and extends in the radial direction of the roller member 10. The gripping member 40 is a portion that is grasped by the user and is joined to the end of the operating shaft 31 side of the shaft member 30. Using the above-described structure, if the user of the adhesive cleaner 1 moves the shaft member 30 in a direction orthogonal to the rotation axis of the roller member 10 while the adhesive surface of the winding body 20r is in contact with the cleaning object, the friction force acting along the circumferential direction of the winding body 20r is generated between the adhesive surface and the cleaning object, so that the winding body 20r can roll on the cleaning object.

[0036] Next, refer to Figure 3 and Figure 4 The adhesive tape 20 of the present embodiment is described in detail. The adhesive tape 20 is in the form of a strip that can be formed into a roll 20r. Hereinafter, regarding the directions of the adhesive tape 20 in a state of being drawn out from the roll 20r along a plane, the first direction in the surface direction of the adhesive tape 20 that is the direction of drawing out from the roll 20r is referred to as the length direction D1, the second direction in the surface direction that is orthogonal to the length direction D1 is referred to as the width direction D2, and the third direction that is orthogonal to both the length direction D1 and the width direction D2 is referred to as the thickness direction D3. In addition, the direction around the winding axis of the roll 20r is referred to as the circumferential direction.

[0037] like Figure 3 As shown in FIG. 1 , the adhesive tape 20 has a plurality of easy-to-cut lines 23 extending in the width direction D2 at predetermined positions in the longitudinal direction D1. The plurality of easy-to-cut lines 23 are formed at predetermined intervals in the longitudinal direction D1 so as to be able to separate the outermost peripheral portion of the winding body 20r whose adhesive strength decreases with use. The easy-to-cut lines 23 of this embodiment are formed by linear perforations, but are not limited thereto and may be formed by known means.

[0038] like Figure 4 As shown, the adhesive tape 20 includes: a surface portion 21 having an adhesive surface, and a base material 22 on which the surface portion 21 is laminated. The surface portion 21 is formed only on one surface of the base material 22. Hereinafter, regarding the surfaces of the adhesive tape 20 itself and each layer of the adhesive tape 20, the surface facing radially outward when forming the wound body 20r is referred to as the front surface, and the surface facing radially inward is referred to as the back surface.

[0039] The surface layer portion 21 of the present embodiment is laminated on the substrate 22 with the surfaces of both side edge portions in the width direction D2 of the substrate 22 (both side edge portions extending in the length direction D1) exposed. In other words, the adhesive tape 20 of the present embodiment includes: a pair of non-adhesive portions 24 (dry edges) constituted by the exposed surfaces of both side edge portions of the substrate 22, and the surface layer portion 21 formed between the pair of non-adhesive portions 24. The width of each non-adhesive portion 24 may be 1 mm to 20 mm, or 3 mm to 15 mm.

[0040] The surface layer portion 21 has an adhesive portion 211 laminated on the surface of the base material 22. The adhesive portion 211 is continuously connected at least in a region between adjacent easy-to-cut lines 23, and forms one layer on the surface of the base material 22.

[0041] The hardness of the adhesive portion 211 is below 0.04 MPa. Thus, the adhesive cleaner 1 can make mites sink into the adhesive portion 211 and capture them. In addition, the hardness of the adhesive portion 211 is above 0.005 MPa, preferably above 0.01 MPa. Thus, it is possible to prevent the adhesive constituting the adhesive portion 211 from adhering to cleaning objects such as carpets. In addition, the traveling property of the winding body 20r can be improved. It should be noted that the hardness of the adhesive portion 211 is measured by the nanoindentation method according to ISO14577. Figure 6 The load-displacement curve obtained by the nanoindentation method shown has: a load curve representing the relationship between the displacement of the sample and the load of the indenter when the indenter is pressed into the sample to a specified depth, and an unloading curve representing the relationship between the displacement of the sample and the load of the indenter when the indenter is pulled out from the aforementioned specified depth. Regarding the specific measurement conditions for obtaining the load-displacement curve, the measurement device used is the "TI950 TriboIndenter" (manufactured by Hysitron). In addition, a spherical Conical indenter with a curvature radius of 10 μm is used as the indenter. The indentation depth of the indenter is set to 3.5 μm, the indentation speed of the indenter is set to 5000 nm / second, and the withdrawal speed is set to 5000 nm / second. The measurement temperature is set to 25°C. In addition, three measurements are performed and their average values ​​are used. Moreover, for hardness, the indenter is pressed to a specified depth h Pmax The load at the end is set as the maximum load P max , will reach h Pmax When the cross-sectional area of ​​the indenter at the contact depth with the sample is set as the contact projection area A, P max / A to calculate.

[0042] The adhesive portion 211 has a thickness of more than 20 μm. The adhesive cleaner 1 can make the mites sink deeper into the adhesive portion 211 and be captured, and can inhibit the mites from falling off after being captured. The thickness of the adhesive portion 211 is more preferably more than 30 μm. On the other hand, if the thickness of the adhesive portion 211 with low hardness is too large, the adhesive portion 211 will have a buffering effect on the mites, so that the mites can survive easily. Therefore, the thickness of the adhesive portion 211 is preferably less than 150 μm, less than 130 μm, less than 100 μm, less than 90 μm, less than 80 μm, less than 70 μm, less than 60 μm, or less than 50 μm. It should be noted that the thickness of the adhesive portion 211 is calculated by enlarging and observing the cross section of the portion drawn out from the winding body 20r along a plane with a microscope, etc., measuring the thickness at any 10 locations, and averaging them.

[0043] The first composition (adhesive composition) constituting the adhesive portion 211 includes at least a polymer, a tackifier, and a plasticizer.

[0044] As the adhesive constituting the adhesive portion 211, for example, acrylic adhesive, rubber adhesive, polyester adhesive, urethane adhesive, polyether adhesive, silicone adhesive, etc. can be used. These adhesives include a base polymer as a main component (the component with the highest mixing ratio). The mass ratio of the base polymer relative to the gross mass of the adhesive is more than 50 mass %, preferably more than 70 mass %, more preferably more than 90 mass %. On the other hand, the mass ratio of the base polymer can be less than 100 mass %, or less than 99 mass %. In terms of obtaining the adhesive portion 211 of a specified hardness, the adhesive is preferably an acrylic adhesive or a rubber adhesive, more preferably a rubber adhesive.

[0045] The rubber-based adhesive contains one or more natural rubbers, natural rubber-based polymers such as modified products of natural rubbers, isoprene rubber, chloroprene rubber, styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene / butylene-styrene block copolymer (SEBS), crystalline polyolefin-ethylene / butylene-crystalline polyolefin block copolymer (CEBC), and styrene-ethylene / butylene-crystalline polyolefin block copolymer (SEBC) as a base polymer.

[0046] The tackifier includes one or more tackifier resins selected from rosin, terpene, hydrocarbon, epoxy, polyamide, elastic, phenolic, ketone, etc. The amount of the tackifier to be added is, for example, 50 to 200 parts by mass, preferably 80 to 150 parts by mass, relative to 100 parts by mass of the base polymer of the adhesive.

[0047] The plasticizer of the adhesive portion 211 includes one or more of process oils selected from paraffin, cycloalkane, aromatic, etc. In order to obtain the adhesive portion 211 of a specified hardness, the amount of the plasticizer blended relative to 100 parts by mass of the base polymer of the adhesive is preferably 50 parts by mass or more, more preferably 80 parts by mass or more, and further preferably 90 parts by mass or more. On the other hand, the amount of the plasticizer blended is preferably 200 parts by mass or less, more preferably 150 parts by mass. Thus, the change in the hardness of the adhesive portion 211 caused by the exudation of the plasticizer during storage can be suppressed.

[0048] The first composition (adhesive composition) constituting the adhesive portion 211 may contain various additives such as an antioxidant, an antioxidant, an ultraviolet absorber, a light stabilizer, an antistatic agent, a lubricant, and a colorant in addition to the above-mentioned substances.

[0049] The hardness of the adhesive portion 211 can be reduced by increasing the amount of a component that is liquid at room temperature (25° C.) among the components of the first composition. Examples of such a component include a plasticizer.

[0050] The adhesive portion 211 of the present embodiment is formed in a transparent state so that the user can visually recognize the color of the surface of the base material 22 .

[0051] The adhesive force of the surface layer 21 of the present embodiment can be 0.1N / 25mm or more and 25N / 25mm or less, preferably 5N / 25mm or more and 20N / 25mm or less. It should be noted that the adhesive force of the surface layer 21 is measured according to the test method described in JIS Z 0237:2022 (Test method for adhesive tapes and adhesive sheets). Specifically, under an environment of temperature 23°C and humidity 50%, a test piece with a width of 25mm (corresponding to the width in the width direction D2) is cut out from the adhesive tape 20, and the test piece is crimped to a SUS steel plate using a crimping device equipped with a 2kg crimping roller. After 30 minutes, the test piece is peeled off 180° relative to the SUS steel plate at a tensile speed of 300mm / min, and the measurement is performed.

[0052] The substrate 22 of this embodiment has a plurality of layers formed by stacking two or more layers. That is, the substrate 22 has a support layer 221 that supports the surface layer portion 21, and an easily peelable layer 222 that promotes peeling from the surface layer portion 21 in the wound body 20r. In addition, although not shown, an intermediate layer is inserted between the support layer 221 and the easily peelable layer 222.

[0053] The support layer 221 of this embodiment is colored blue, and the user can visually recognize the coloring through the transparent adhesive portion 211. As a result, the user can visually recognize that the adhesive portion 211 has captured whitish mites, which can increase the user's enthusiasm for cleaning. It should be noted that the coloring of the substrate 22 is not limited to the coloring of the support layer 221. For example, the support layer 221 can be made transparent, and the layer on the back side of the support layer 221 can be colored. In addition, the coloring is not limited to blue, for example, it can also be a color corresponding to the electromagnetic waves that constitute visible light, or black, dark gray, etc.

[0054] The back side of the easily peelable layer 222 of this embodiment is made of a silicone-based surface treatment agent, making it easy to peel from the surface layer 21. The surface treatment agent is not limited to the above, and may be a fluorine-based surface treatment agent or a long-chain alkyl-based surface treatment agent, for example.

[0055] The intermediate layer may be composed of a film made of polyolefin such as polyethylene, for example.

[0056] The thickness of the substrate 22 is, for example, 10 μm or more, 25 μm or more, 40 μm or more, or 50 μm or more. The thickness of the substrate 22 is, for example, 200 μm or less, 150 μm or less, or 100 μm or less.

[0057] The width of the substrate 22 is preferably 30 mm or more, 50 mm or more, or 100 mm or more. In addition, the width of the substrate 22 is preferably 500 mm or less, 400 mm or less, 300 mm or less, or 200 mm or less.

[0058] Next, refer to Figure 5 A modified example of the adhesive tape 20 will be described. It should be noted that in the description of the modified example of the adhesive tape 20, Figure 1 to Figure 4 The adhesive tape 20 shown has substantially the same structure, and is denoted by reference numerals and the description thereof is omitted.

[0059] like Figure 5 As shown, the adhesive tape 20 of the modified example includes a surface portion 21 having: an adhesive portion 211 laminated on the surface of a substrate 22, and a plurality of protrusions 212 having a weaker adhesive force than the adhesive portion 211 and protruding from the surface of the adhesive portion 211 in the thickness direction D3.

[0060] The plurality of protrusions 212 extend in one direction of the surface direction of the adhesive tape 20 and are formed at predetermined intervals in a direction orthogonal to the one direction. More specifically, the plurality of protrusions 212 extend in the length direction D1 and are formed at intervals d in the width direction D2. In the wound body 20r, the plurality of protrusions 212 protrude radially outward.

[0061] The protrusion 212 of this embodiment has a quadrilateral cross section perpendicular to the length direction D1, and is in the shape of an elongated strip when viewed from one side in the thickness direction D3. It should be noted that the present invention is not limited thereto, and the protrusion 212 may also be in the shape of a trapezoid that becomes thinner toward the front end surface, or the front end surface may also be circular.

[0062] Through the adhesive portion 211 and the plurality of protrusions 212 as described above, the surface portion 21 has: a plurality of first contact surfaces 21a consisting of a strong adhesive surface belonging to the exposed surface of the adhesive portion 211, and a plurality of second contact surfaces 21b consisting of a weak adhesive surface belonging to the front end surface of each protrusion 212. The first contact surface 21a and the second contact surface 21b can be surfaces that come into contact with the cleaning object when in use. More specifically, the first contact surface 21a of the adhesive portion 211 mainly contacts with the cleaning object having a large uneven surface such as a carpet and a velvet rug, which helps to capture foreign matter attached to them. The second contact surface 21b of the protrusion 212 mainly contacts with the cleaning object having a smooth surface with few uneven surfaces such as a floor, which helps to capture foreign matter attached to them.

[0063] Each protrusion 212 is made of a second composition that can provide the protrusion 212 with an adhesive force weaker than that of the adhesive portion 211 and make the protrusion 212 harder than the adhesive portion 211. That is, each protrusion 212 has an adhesive force weaker than that of the adhesive portion 211.

[0064] In the winding body 20r, each protrusion 212 overlaps in the radial direction (from the innermost circumference to the outermost circumference of the winding body 20r) to form a plurality of winding parts extending in the radial direction. In addition, a plurality of winding parts are formed at intervals in the width direction D2 of the winding body 20r. The winding part of this embodiment shows a more significant hardness than the winding part formed by the adhesive part 211 due to the overlapping of the hard protrusions 212. Moreover, the winding part formed by the protrusions 212 has excellent resistance to the squeezing force from above when the winding body 20r moves, and is not easy to deform. Through such an effect, in this embodiment, it becomes easy for the protrusions 212 to perform their functions.

[0065] The first contact surface 21a and the second contact surface 21b of the nth week of the winding body 20r are surfaces that can contact the back side of the n+1th week (i.e., the back side of the substrate 22). By such contact between the surface of the nth week and the back side of the n+1th week, the phenomenon of the winding of the winding body 20r loosening when not in use (loose winding) and the phenomenon that the outer peripheral surface of the winding body 20r is sequentially attached to the cleaning object (rail pulling phenomenon) can be suppressed. In this embodiment, the adhesive force of the adhesive portion 211 is relatively strong, and thus, there is a concern that the first contact surface 21a is hindered from peeling off from the back side of the substrate 22, thereby making it difficult to lead out the winding body 20r. In contrast, in this embodiment, the protrusion portion 212 with a protrusion height of more than 40μm partially hinders the first contact surface 21a from sticking to the back side of the substrate 22. Although the adhesive force of the adhesive portion 211 is strong, the winding body 20r is easy to lead out.

[0066] The second composition constituting the protrusion portion 212 contains a polymer different from the polymer contained in the first composition (adhesive composition) of the adhesive portion 211 , and may further contain a plasticizer.

[0067] Examples of the polymer of the protrusion 212 include polyolefins such as polyethylene (PE), polypropylene (PP), and ethylene-propylene copolymers.

[0068] The second composition constituting the protrusion 212 may contain various additives such as an antioxidant, an antioxidant, an ultraviolet absorber, a light stabilizer, an antistatic agent, a lubricant, and a colorant in addition to the above.

[0069] Next, a method for producing the pressure-sensitive adhesive tape 20 according to the present embodiment will be described.

[0070] The manufacturing method of the adhesive tape 20 of this embodiment is not limited to the following method, and includes: an adhesive portion forming step of forming a layered adhesive portion 211 on the surface of a substrate 22, and a ridge forming step of forming a plurality of ridges 212 on the surface of the adhesive portion 211 as needed.

[0071] In the manufacturing method of this embodiment, the first composition and the second composition are molten. Then, the first composition is applied to the surface of the substrate 22 using a coating device such as a die coater, and the second composition is applied to the coating film formed by the molten first composition. That is, the manufacturing method of this embodiment adopts a wet-on-wet method.

[0072] In the case of increasing the hardness, elastic modulus, and the slope of the load curve of the bonding portion 211, for example, a polymer with a high elastic modulus can be mixed in the first composition. In addition, by designing the thickness of the bonding portion 211 to be larger, these physical property values ​​can also be increased. On the other hand, in order to reduce the hardness, elastic modulus, and the slope of the load curve of the bonding portion 211, for example, a polymer with a low plasticizer or elastic modulus can be mixed in the first composition. In addition, by designing the thickness of the bonding portion 211 to be less, these physical property values ​​can also be reduced.

[0073] In order to increase the minimum load of the load curve and the minimum load of the unloading curve of the adhesive portion 211, for example, a material with poor adhesiveness may be mixed more in the first composition. On the other hand, in order to reduce the minimum load of the load curve and the minimum load of the unloading curve of the adhesive portion 211, for example, a material with high adhesiveness may be mixed more in the first composition.

[0074] It should be noted that the sticky cleaner of the present invention is not limited to the above-mentioned embodiment. In addition, the sticky cleaner of the present invention is not limited to the above-mentioned effects. The sticky cleaner of the present invention can be modified in various ways without departing from the scope of the present invention.
