Description

The present invention relates to a wiper dispenser and a method for installing the wiper dispenser.

A wiper dispenser is used that stores wet wipes or dry wipes (hereinafter, these may be collectively referred to as "wipers") for disinfection, sterilization, or sanitization purposes. A wiper dispenser can store a large number of wipes.

Fig. 12 is a perspective view of an example of a conventional wiper dispenser, and Fig. 13 is a schematic cross-sectional view for explaining the use state of the wiper dispenser of Fig. 12. Fig. 13 is a cross-sectional view of the wiper dispenser of Fig. 12 taken along line A-A, and shows a schematic diagram of the wiper dispenser being used after being installed on an installation stand 200.

The conventional wiper dispenser 100 is a so-called pop-up type wiper dispenser. The wiper dispenser 100 comprises a container body 10 in which a wiper W can be stored from an opening 13 at the top end, and a first lid body 20 connected via a first hinge portion 22. The first hinge portion 22 is provided around the edge of the opening 13 at the top end of the container body 10, which allows the first lid body 20 to rotate around the first hinge portion 22. The first lid body 20 is provided with a first grip portion 21 that can be grasped by a user, making it easy to open and close the first lid body 20.

The first lid 20 has an opening 23 formed on its top surface for removing the wiper W, and is equipped with a second lid 24 connected via a second hinge portion 26. The first lid 20 has a recess 27 formed on its top surface that can fit with the second lid 24, and the opening 23 is formed on the bottom surface of this recess 27. This opening 23 is a through hole that is approximately elliptical in top view, communicates with the container body 10, and allows the wiper W to be removed from here.

The second hinge portion 26 that connects the second lid body 24 to the first lid body 20 is provided around the end of the access opening 23 of the first lid body 20, which allows the second lid body 24 to rotate around the second hinge portion 26 (see arrow R in FIG. 13). The second lid body 24 is also provided with a second grip portion 25 that can be grasped by the user, making it easy to open and close the second lid body 24.

The wiper dispenser 100 is used, for example, as follows:

First, when a user fills the wiper dispenser 100 with a stack of wipers W (when filling), the user opens the first lid 20 and opens the opening 13 at the top end of the container body 10. The wipers W are stored in the container body 10 through this opening 13 at the top end. The first lid 20 is then closed to block the opening 13 at the top end of the container body 10. This allows the wipers W to be stored in the container body 10 without coming into contact with the outside.

Next, when the user removes a wiper from the wiper dispenser 100 (when in use, see FIG. 13), the user opens the second lid 24 (see arrow R in FIG. 13) to open the removal opening 23. The user picks up the end of the first wiper W1 protruding from this removal opening 23 and pulls it upward (see arrow F1 in FIG. 13). By repeating this action, the user can sequentially remove the required number of wipers W1, W2, and W3 from the removal opening 23. After removing the wiper W, the user closes the second lid 24 (see arrow R in FIG. 13) to close the removal opening 23.

The wipers W are alternately folded and stacked so that they can be taken out continuously from the outlet 23. For example, wiper W2 is alternately folded and stacked so that it interlocks with the adjacent wiper W1 above it and the adjacent wiper W3 below it. The stack of wipers W stacked in this way is stored in the container body 10.

Regarding such a wiper dispenser, Patent Document 1 is disclosed, which presents a dispenser structure that is easier to use. Patent Document 2 also proposes providing an attachment to the wiper dispenser as an improved technology for such a wiper dispenser. For example, Patent Document 2 discloses an attachment that includes an attachment body that is provided on the dispenser body and is positioned between the dispenser body's outlet and the laminate, and a wiper passage portion that is formed on the attachment body by a notch or through-hole through which a wet wiper can pass and has an opening area smaller than the opening area of the outlet.

However, in order to further improve the wiper dispenser, the inventors observed the use of the wiper W in the conventional wiper dispenser 100, and found that the user rarely pulls out the wiper W vertically (for example, in the up-down direction in FIG. 13, see arrow F2) from the outlet 23 of the wiper dispenser 100 provided on the stand, but rather pulls it out slightly diagonally upward as if pulling it towards their body. Therefore, the inventors noticed that the wiper dispenser 100 moves unintentionally on the installation surface 210 (for example, see arrows F2 and F3 in FIG. 13), causing the wiper dispenser 100 to shift position. In severe cases, the wiper dispenser 100 falls off the installation stand 200. In particular, if some of the parts constituting the wiper dispenser 100 are made of resin, the wiper dispenser may be damaged by falling. Also, if some of the parts constituting the wiper dispenser 100 are made of metal, the wiper dispenser may be deformed by falling.

This problem is particularly noticeable in a usage situation where many users frequently take out wipers W from all four sides of the wiper dispenser 100, such as a commercial dispenser. When each person takes out a wiper W in their own direction, the wiper dispenser 100 repeatedly shifts position on the table in the direction of the wiper W being taken out. This type of position shift is undesirable for the wiper dispenser 100, which is desired to be managed in a fixed position.

In order to prevent the wiper dispenser 100 from shifting out of position or falling off, a method is used in which the bottom surface 11 of the wiper dispenser 100 is fixed to the installation stand 200 with double-sided tape or adhesive. However, such double-sided tape and adhesive have too strong an adhesive force, making it difficult to remove the wiper dispenser 100 from the installation stand 200.

As such, when the wiper dispenser 100 is in use, it is desirable that the wiper dispenser 100 does not shift from the installation surface 210. At the same time, it is also desirable that the wiper dispenser 100 can be easily removed from the installation surface and carried around. However, the current situation is that it is not possible to satisfy all of these demands.

The present invention was made in consideration of these circumstances, and aims to provide a wiper dispenser and a method for installing a wiper dispenser that will not shift out of position when in use and that is easy to remove from the installation surface and to carry.

As a result of intensive research into achieving the above-mentioned object, the inventors discovered how to adhere a support material having a specific structure to a portion of the outer surface of the bottom of a resin or metal container body, and control the arrangement of the adhered and non-adhered areas of the support material on the outer surface of the bottom, and have completed the present invention based on this discovery.

＜Wiper dispenser＞

Figure 1 is a schematic cross-sectional view of a wiper dispenser according to a first embodiment, Figure 2 is a partially enlarged view for explaining the support material of the wiper dispenser of Figure 1, and Figure 3 is a schematic view from the bottom side for explaining the arrangement of the support material of the wiper dispenser according to the first embodiment.

The wiper dispenser 1 according to this embodiment comprises a resin or metal container body 10 having at least a substantially rectangular bottom surface 11 and a side wall 12 erected from the bottom surface 11, a first lid body 20 capable of closing an opening 13 formed by the side wall of the container body 10, and a support material 30 adhered to a part of the outer surface of the bottom surface 11 of the container body 10. A stack of wipers W is stored in the container body 10, and the opening 13 is closed by the first lid body 20 for storage.

(Container body 10 and first lid body 20)

The container body 10 and the first lid body 20 can be the conventional wiper dispenser 100 (see Figs. 12 and 13). Furthermore, the configuration of the container body 10 and the first lid body 20 is not limited to the same as that of the wiper dispenser 100 shown in Figs. 12 and 13, and may be any configuration in which the support material 30 can be attached to the bottom surface 11 of the container body 10. Therefore, for example, the bottom surface 11 and the side wall 12 are connected by a curved surface, but this is not limited thereto, and they may be connected at a right angle or an obtuse angle that is approximately a right angle as in Fig. 1, without having a curved surface, or a commercially available wiper dispenser made of resin or metal may be used.

Examples of resins used in the container body 10 include biodegradable resins such as polypropylene, polyethylene, polystyrene, ABS resin, PET resin, vinyl chloride resin, and polybutylene succinate. Examples of metals used in the container body 10 include stainless steel, aluminum, and titanium. The material of the first lid 20 is not particularly limited, but may be the above-mentioned resins, transparent rubber, metal, or a combination of these.

(Wiper W)

The wiper W stored in the container body 10 may be either a wet wiper or a dry wiper. The wiper W is used in various places, such as medical facilities, laboratories, precision parts factories, food processing plants, school lunch centers, and restaurants. The wiper W is used to wipe down equipment, supplies, and various container packaging, as well as for cleaning the site.

The wiper W includes, for example, a substrate formed of nonwoven fabric and a chemical solution impregnated into the substrate. For example, by impregnating the substrate with a chemical solution having sterilizing, disinfecting, and/or antibacterial properties, such as alcohol or hypochlorous acid water, the wiper can be made into a wet wiper with the required hygienic properties. Furthermore, the wiper W is not limited to a wet wiper, and may be a dry wiper.

The wiper W may also be colored with a coloring agent so that it is easy to detect if it is left behind or mixed in with food or its packaging, for example, during the food manufacturing process.

The coloring agent for coloring the wiper W is not particularly limited, and examples thereof include direct dyes, cationic dyes, basic dyes, acid dyes, and other dyes generally used for coloring textiles and paper, natural dyes, food dyes, dye-based inks, and pigment-based inks. Among these, from the viewpoint of dyeability and weather resistance, direct dyes, cationic dyes, and pigment-based inks are preferred. The color is not particularly limited, and can be appropriately selected depending on the application, such as red, blue, yellow, etc.

The type of nonwoven fabric that is the substrate is not particularly limited, and examples include those that are made by laminating and integrating fibers such as rayon fibers, polyester fibers, polypropylene fibers, polyamide fibers, polyethylene fibers, acrylic fibers, cotton, and wool, either alone or in combination. The method of integration is not particularly limited, and any method that can maintain a strength that does not generate lint when used as a wiper can be used, and examples include methods using binder adhesion, heat fusion, water jet, and needle punching.

(Support material 30)

The support material 30 comprises an adhesive layer 31 containing an adhesive, which is adhered to the outer surface of the bottom surface 11 of the container body 10, and a magnetic layer 32 containing an anisotropic magnet, which is laminated on the surface of the adhesive layer 31 opposite to the surface adhered to the outer surface. The adhesive layer 31 preferably has an adhesive force that allows it to be fixed to the bottom surface 11 of the container body 10 so as not to fall off from the bottom surface 11. On the other hand, the magnetic layer 32 preferably has a magnetic force that allows it to be magnetically attached to, for example, a metal installation surface 210, and can be easily removed from the installation surface 210 by inserting a finger or fingernail into the bottom surface 11 of the container body 10 as described below.

Furthermore, it is preferable that the adhesive force of the adhesive layer 31 to the container body 10 and the magnetic layer 32 is stronger than the magnetic force of the magnetic layer 32 to the installation surface 210. When the wiper dispenser 1 is removed from the installation surface 210, the magnetic layer 32 does not separate from the installation surface 210, and this can prevent the adhesive surface between the adhesive layer 31 and the container body 10, or the adhesive surface between the adhesive layer 31 and the magnetic layer 32, from peeling off. From this perspective, it is preferable that the adhesive force of the adhesive layer 31 is stronger than the magnetic force of the magnetic layer 32, and that the materials are selected accordingly.

(Adhesive layer 31)

The type of adhesive contained in the adhesive layer 31 is not particularly limited, and may be any type that can be bonded to the container body 10 made of resin or metal. Examples of adhesives that have high adhesive strength to the container body 10 include acrylic adhesives, epoxy adhesives, ethylene-vinyl acetate adhesives, urethane adhesives, silicone adhesives, and rubber adhesives. Among these, acrylic adhesives are preferred from the viewpoints of high adhesive strength to the resin used as the material of the container body 10, stability against light and oxygen, heat resistance, and chemical resistance. Rubber adhesives are preferred from the viewpoints of excellent initial adhesive strength, fewer restrictions on the material of the adherend (e.g., the container body 10 and the magnetic layer 32), and ability to adhere to a relatively large number of materials. Furthermore, silicone adhesives are preferred from the viewpoints of compatibility with a wide temperature range and excellent weather resistance, chemical resistance, and moisture resistance.

The adhesive layer 31 preferably further includes a nonwoven fabric. In this case, a suitable embodiment is a double-sided tape. When using the wiper dispenser 1, every time the wiper W is taken out of the outlet 23, an impact due to misalignment is applied. For this reason, it is preferable to use a double-sided tape with excellent impact resistance as the adhesive layer 31, and in particular, a double-sided tape in which an adhesive is applied to the front and back surfaces of a substrate is more preferable. A double-sided tape without a substrate has a single-layer structure of only adhesive, whereas a double-sided tape with a substrate has a three-layer structure of an adhesive layer, a substrate layer, and an adhesive layer from the front to the back, and therefore has a thickness that provides a gap buffering function. When the container body 10 and the magnetic layer 32 are bonded with the double-sided tape, even if there is a gap such as some unevenness or inclination on the contact surface between the container body 10 and the magnetic layer 32, the thickness of the double-sided tape including the substrate serves as a gap filling function, and the container body 10 and the magnetic layer 32 can be bonded with a large contact area.

The thickness of the double-sided tape is preferably 0.015 to 1.00 mm. If it is 0.015 mm or more, the gap-filling function is further improved. On the other hand, if it is 1.00 mm or less, even if a horizontal force is applied to the dispenser placed on the stand, the thickness of the adhesive layer can reduce the force that twists the adhesive layer 34 on the magnetic layer side of the double-sided tape and the adhesive layer 31 on the bottom side of the dispenser in the horizontal direction, making it difficult for the double-sided tape to peel off from the magnetic layer surface or the dispenser surface.

The adhesive layer 31 containing nonwoven fabric and adhesive may be, for example, a laminated sheet in which a layer containing the above-mentioned adhesive is laminated on both sides of a substrate (e.g., nonwoven fabric, pulp fiber sheet, resin film, porous sheet such as acrylic foam, and laminates thereof). In this case, the adhesive is preferably the above-mentioned acrylic adhesive, rubber adhesive, or silicone adhesive, and more preferably an acrylic adhesive. Acrylic adhesives are particularly suitable because of their excellent adhesion to nonwoven fabric.

(Magnetic layer 32)

The magnetic layer 32 is formed using an anisotropic magnet. The orientation of the crystals in the anisotropic crystal arrangement of the anisotropic magnet is fixed in the direction of easy magnetization, so a strong magnetic attraction force can be secured in that direction. This allows the magnetic force to be directed in a specific direction (see, for example, arrow F5 in Figure 2), and the magnetic force is stronger than that of an isotropic magnet made of the same material. The anisotropic magnet may be either one-sided magnetized or double-sided multi-pole magnetized, but one-sided magnetization is preferable.

By using the above-mentioned anisotropic magnet as the magnetic layer 32, the magnetic attraction force (hereinafter sometimes abbreviated as "magnetic attraction force") to the installation surface 210 becomes moderately strong due to the magnetic orientation of the anisotropic magnet, and the horizontal static friction coefficient and dynamic friction coefficient for the contact surface between the magnetic layer 32 and the installation surface 210 become high. This makes it possible to effectively suppress horizontal positional deviation of the dispenser. For example, the wiper dispenser 1 can be stably installed on a metal (iron, etc.) installation stand 200 or the installation surface 210, which is a side wall. It is also possible to make the magnetic layer 32 thinner and lighter.

From this viewpoint, the magnetic adhesion force (magnetic attraction force) of the magnetic adhesion layer 32 is preferably 30 to 160 g/cm ^2. The lower limit of the magnetic attraction force is more preferably 40 g/cm ² or more, and even more preferably 88 g/cm ² or more. The upper limit of the attraction force is more preferably 160 g/cm ² or less, and even more preferably 145 g/cm ² or less.

The magnetic attraction force (magnetic adhesion force) referred to here is a value measured by contacting a magnet with an iron plate, pulling it perpendicular to the vertical axis using a load cell, and dividing the force exerted when the magnet separates from the iron plate by the contact area of the magnet. The measurement conditions are that the thickness of the iron plate (T) is equal to or greater than the thickness of the magnet (H), the magnet is placed at the center of the iron plate, the area of the iron plate is at least three times the area of the magnet, the material of the iron plate is pure iron, the surface of the iron plate is flat with no irregularities, there is no coefficient of friction, and there is no gap between the iron plate and the magnet with a tight fit.

Types of anisotropic magnets include, for example, ferrite magnets, neodymium magnets, cobalt magnets, alnico magnets, and composite magnets of these. In addition, the magnets may be composites in which powder of these magnets is mixed with a binder (e.g., resin and/or rubber).

The magnetic force generally tends to be weaker in the order of neodymium magnets (strong), cobalt magnets, alnico magnets, and ferrite magnets (weak). In this trend, the magnetic forces of neodymium magnets, cobalt magnets, and alnico magnets tend to be stronger than the adhesive force of the adhesive layer 31, so ferrite magnets are more preferable as the magnets used in this embodiment. Although ferrite magnets have a relatively weaker magnetic force than the other types of magnets mentioned above, by using an anisotropic type magnet, it is possible to sufficiently magnetically attach the magnet to the installation surface 210, and as mentioned above, it is possible to control the magnetic force to be lower than the adhesive force of the adhesive layer 31.

The chemical resistance of magnets generally tends to decrease in the order of ferrite magnets (high), cobalt magnets, alnico magnets, and neodymium magnets (low). The wiper dispenser 1 is often used together with chemicals such as alcohol or hypochlorous acid water, and the chemicals adhere to the magnetic layer 32 during use. However, ferrite magnets have excellent chemical resistance, so they can more effectively prevent rust and loss of magnetic force due to the adhesion of chemicals.

From the above viewpoint, a specific example of the magnetic layer 32 is preferably an anisotropic magnet sheet, more preferably an anisotropic ferrite magnet sheet, and even more preferably an anisotropic ferrite magnet rubber sheet. The rubber sheet referred to here can be a composite mixed with the binder described above.

Furthermore, if the magnetic sheet is a rubber type, it has excellent conformability and can be adhered closely to the entire surface of the mounting surface 210, even if the mounting surface 210 is a rough surface with unevenness. It can also prevent the mounting surface 210 from being scratched.

(Arrangement of adhesive area S1 and non-adhesive area S2)

The support material 30 is adhered to the container body 10 in the following manner so that the bottom surface 11 can be easily inserted with a finger or fingernail. First, the outer surface of the bottom surface 11 of the container body 10 is adhered so as to have an adhered region S1 to which the support material 30 is adhered, and a non-adhesive region S2 to which the support material 30 is not adhered. Then, when the outer surface is divided into m equal intervals in a first direction (e.g., horizontal direction) (m is an integer between 3 and 40) and into n equal intervals in a second direction (e.g., vertical direction) perpendicular to the first direction (n is an integer between 3 and 40), the non-adhesive region S2 is adhered so as to include at least the peripheral section that is in contact with the periphery of the outer surface when the outer surface is divided into a plurality of sections (e.g., see FIG. 3).

The ratio of the lengths in the first and second directions is preferably set to 1:3 to 3:1, in accordance with the aspect ratio of the wiper stack. Any dimension ratio outside this range is not suitable for a wiper, as the sheet size that can be stored in the stacked state will be elongated.

Therefore, when a user lifts the wiper dispenser 1 from the installation stand 200 and moves it, a space can be secured in which a finger or fingernail can be inserted into the bottom surface 11 of the container body 10 (see arrow F4 shown in the partially enlarged view of area B in FIG. 1). This makes it easy to remove and lift the wiper dispenser 1 from the installation surface 210. In this embodiment, the arrangement of the adhesive region S1 and the non-adhesive region S2 can be controlled to facilitate removal and lifting.

The arrangement of the adhesive region S1 and the non-adhesive region S2 will be described below as an example with reference to Figure 3. Figure 3 shows an embodiment in which the outer surface of the bottom surface 11 of the container body 10 is roughly rectangular, and is divided into 5 equal intervals horizontally (when m = 5, see x1 to x5 in Figure 3) and 7 equal intervals vertically (when n = 7, see y1 to y7 in Figure 3), resulting in a total of 35 (5 x 7) sections.

For convenience, in this specification, a section may be specified by its horizontal and vertical coordinates. For example, the section located in the leftmost column and bottom row of FIG. 3 is called "(x1, y1)." A section that includes the periphery of the bottom surface 11 is called a "peripheral section." A section that is surrounded on all four sides is called "surrounded," and a section that is surrounded in this way is called a "surrounding section."

Figure 3 illustrates an embodiment in which the non-adhesive region S2 includes all of the peripheral sections (a total of 20 sections: (x1, y1), (x1, y2), (x1, y3), (x1, y4), (x1, y5), (x1, y6), (x1, y7), (x2, y1), (x2, y7), (x3, y1), (x3, y7), (x4, y1), (x4, y7), (x5, y1), (x5, y2), (x5, y3), (x5, y4), (x5, y5), (x5, y6), and (x5, y7)). Figure 3 also illustrates an embodiment in which the adhesive region S1 is a surrounding section surrounded by the non-adhesive region S2. In this case, a space is provided on all four sides that allows a finger or fingernail to be inserted from the bottom surface 11.

In this embodiment, the non-adhesive region S2 does not have to include all of the peripheral sections, but only needs to include at least one of the peripheral sections. Also, the adhesive region S1 does not have to be a surrounding section, but may include the peripheral section. Such modified examples are described in other embodiments described below.

Usually, the thickness of a human fingernail is said to be about 0.3 to 0.8 mm, which is generally less than 1 mm. For this reason, it is preferable that the thickness of the magnetic layer 32 is 1 to 3 mm. By setting the lower limit of the thickness of the magnetic layer 32 to 1 mm or more, a gap large enough to insert at least a fingernail can be formed between the wiper dispenser 1 and the installation surface 210 (for example, see arrow F4 in the enlarged partial view of area B in FIG. 1). In addition, by setting the upper limit of the thickness of the magnetic layer 32 to 3 mm or less, a moderate magnetic force can be maintained. If it is 3 mm or less, the magnetic force is not too strong and it is not difficult to pull it up using a fingernail. For example, the wiper dispenser 1 can be removed from the installation surface 210 by inserting the left and right hands into the gap between two opposing peripheral sections (for example, (x1, y4) and (x5, y4), (x3, y1) and (x3, y7) in FIG. 3) and pulling it up perpendicularly to the installation surface 210. Furthermore, from the above viewpoint, the thickness T1 of the support material 30 is preferably 1 to 4 mm. The lower limit of the thickness T1 is more preferably greater than 1 mm, more preferably greater than 2 mm, and even more preferably greater than 2.5 mm. The upper limit of the thickness T1 is more preferably 3.5 mm or less, even more preferably 3.3 mm or less, and even more preferably 3.1 mm or less.

The lower limit of m and n is 3 or more. By dividing into three or more, at least one surrounding section can be formed. The upper limit of m and n is 40 or less. If divided into more than 40, the length of each section will be shorter. As a result, it becomes difficult to ensure a sufficient depth to insert a finger or fingernail from the non-adhesive region S2. From this perspective, the upper limit of m and n is preferably 35 or less, more preferably 30 or less, even more preferably 20 or less, even more preferably 15 or less, and even more preferably 13 or less. The lower limit of m and n is preferably 5 or more, more preferably 8 or more, and even more preferably 10 or more. Note that m and n may be the same or different.

Furthermore, according to this embodiment, the area ratio (S1/(S1+S2)) of the adhesive region S1 to the outer surface of the bottom face 11 is preferably 10 to 90%. The lower limit of this area ratio is more preferably 30% or more, even more preferably 35% or more, even more preferably 40% or more, even more preferably 60% or more, and even more preferably 65% or more. The upper limit of this area ratio is more preferably 80% or less, and even more preferably 70% or less.

From the viewpoint of facilitating lifting by inserting a finger or fingernail, it is preferable that the non-adhesive region S2 includes one or more pairs of opposing peripheral sections, and more preferably includes two or more pairs of peripheral sections. The "one pair of opposing peripheral sections" here refers to those that are in a positional relationship such as a pair of (x1, y4) and (x5, y4) and a pair of (x3, y1) and (x3, y7) in FIG. 3. The "two pairs of opposing peripheral sections" refer to those that are in a positional relationship such as two pairs of (x1, y4) (x1, y5) and (x5, y4) (x5, y5) and two pairs of (x3, y1) (x4, y1) and (x3, y7) (x4, y7) in FIG. 3. In this regard, the wiper dispenser 1 has opposing peripheral sections included in the non-adhesive region S2 on each of two pairs of opposing sides (horizontal and vertical sides in FIG. 3) on the outer surface of the bottom surface 11. This makes it easy to insert opposing fingers or fingernails of both hands from either the horizontal or vertical sides, and the dispenser can be removed by holding it symmetrically left and right, up and down, or up and down and left and right, and the worker can remove the dispenser from the wall surface without losing his or her balance.

Figure 4 is a schematic diagram seen from the bottom side to explain the arrangement of the support material of the wiper dispenser according to the second embodiment.

4 differs from FIG. 3 in the arrangement of the adhesive region S3 and the non-adhesive region S4, but is otherwise the same. In the wiper dispenser 2, the adhesive region S3 encompasses the four corner sections of the bottom surface 11 (e.g., (x1, y1), (x1, y7), (x5, y1), (x5, y7)). For example, at a work site where the wiper dispenser 2 is used, fingers may be wet. In that case, a finger or fingernail inserted into the gap between the bottom surface 11 and the installation surface 210 may slip in the horizontal direction of the bottom surface 11 (toward the paper surface of FIG. 4). However, since the four corner sections are adhesive regions S1, these function as stoppers and can prevent the finger from slipping. At least one of the four corner sections may be adhesive region S1, but from the viewpoint of the effect as a stopper described above, in this embodiment, preferably two or more of the four corner sections, more preferably three or more of the four corner sections, and even more preferably all of the four corner sections are encompassed by adhesive region S1.

Figure 5 is a schematic diagram seen from the bottom side to explain the arrangement of the support material of the wiper dispenser according to the third embodiment.

Figure 5 differs from Figure 4 in the arrangement of the adhesive region S5 and non-adhesive region S6, but is otherwise the same. One of the peripheral sections is a non-adhesive region S6, and the sections adjacent to that section are all adhesive regions S5. For example, looking at one section (x1, y3) which is a non-adhesive region S6, the adjacent sections (x1, y2), (x1, y4), and (x2, y3) are adhesive regions S5. In this way, if the area ratio of the adhesive region S5 to the outer surface of the bottom surface 11 is high, the magnetic force can be further improved. For example, if the wiper dispenser 3 is relatively large, it is preferable to increase the number of sections of the adhesive region S5 in this way.

Figure 6 is a schematic diagram seen from the bottom side to explain the arrangement of the support material of the wiper dispenser according to the fourth embodiment.

6 differs from FIG. 3 in the arrangement of the adhesive region S7 and the non-adhesive region S8, but is otherwise the same. Specifically, the adhesive region S7 is arranged in the center of the outer surface of the bottom surface 11, and another non-adhesive region S8 (e.g., (x3, y3), (x3, y4), (x3, y5)) is provided within the adhesive region S7, which is arranged in the center of the outer surface of the bottom surface 11, to reduce the number of sections of the adhesive region S7. Since the area ratio of the adhesive region S7 to the outer surface of the bottom surface 11 is low in this way, the magnetic force is suppressed to a certain extent, and it is easy to remove from the installation surface 210. For example, if the device is often used by people with weak strength, it is preferable to reduce the number of sections of the adhesive region S7 in this way. In that case, it is preferable that the adhesive region S7 is arranged so as to surround the non-adhesive region S8, as shown in FIG. 6. This allows the magnetic force to be maintained at an appropriate strength and to be evenly distributed over the outer surface of the bottom surface 11.

As shown in FIG. 6, the adhesive area S7 of the wiper dispenser 4 is arranged so as to be linearly symmetrical with respect to the center line passing through the center of gravity of the outer surface of the bottom surface 11, so that the wiper dispenser 4 can maintain a sufficient magnetic force even if the number of sections of the adhesive area S7 is at a minimum.

Figure 7 is a schematic diagram seen from the bottom side to explain the arrangement of the support material of the wiper dispenser according to the fifth embodiment.

Figure 7 differs from Figure 4 in the arrangement of the adhesive region S9 and non-adhesive region S10, but is otherwise the same. Also, compared to the wiper dispenser 2 shown in Figure 4, Figure 7 reduces the number of sections of the adhesive region S9 by providing separate non-adhesive regions S10 (e.g., (x3, y3), (x3, y4), (x3, y5)) surrounded within the adhesive region S9 located at the center of the outer surface of the bottom surface 11. Therefore, this wiper dispenser 5 has a lower area ratio occupied by the adhesive region S9 compared to the wiper dispenser 2 in Figure 4, which reduces the magnetic force to a certain extent and makes it easier to remove from the installation surface 210.

Figure 8 is a schematic diagram seen from the bottom side to explain the arrangement of the support material of the wiper dispenser according to the sixth embodiment.

Figure 8 differs from Figure 3 in the arrangement of the adhesive region S11 and the non-adhesive region S12, but is otherwise the same. As shown in Figure 8, the adhesive region S11 may be only a part of a partition unit (one partition) into which the outer surface is divided (e.g., (x2, y2), etc.). However, even in such a case, from the viewpoint of ensuring a depth sufficient to insert a finger or fingernail, at least one of the peripheral partitions included in the non-adhesive region S12 (preferably two or more opposing peripheral partitions) is non-adhesive over the entire area of the unit partition.

In this embodiment, the shape of the magnetic layer 32 is not particularly limited, but is any one selected from the group consisting of a rectangle, a triangle, an ellipse, a circle, and a polygon, and is preferably arranged so that the shape of the magnetic layer 32 is line-symmetrical with respect to a center line passing through the center of gravity of the outer surface, or point-symmetrical with respect to the center of gravity. By arranging in this manner, the magnetic force can be exerted over the entire outer surface, and it becomes easy to remove from the four periphery of the bottom surface 11. It also has excellent design. Figure 8 shows an example in which the shape of the magnetic layer 32 is an ellipse.

In particular, when the magnetic layer 32 has a complex shape, it is preferable to use the above-mentioned magnetic sheet as the magnetic layer 32. By using a magnetic sheet, the magnetic layer 32 can be easily cut to the desired shape.

Figure 9 is a schematic cross-sectional view of a support material for a wiper dispenser according to the seventh embodiment.

The wiper dispenser 7 differs from the wiper dispenser 1 of FIG. 1 in that the support material 40 includes an adhesive layer 31, a spacer layer 33 laminated on the surface of the adhesive layer 31, another adhesive layer 34 laminated on the surface of the spacer layer 33, and a magnetic layer 32 laminated on the surface of the other adhesive layer 34. The support material 40 further includes a spacer layer 33 to ensure thickness.

The thicker the magnetic layer 32, the easier it is to form a space for inserting a finger or fingernail. However, from the viewpoint of controlling the magnetic force suitable for removing the magnetic sheet from the installation surface, and from the viewpoint of the difficulty in obtaining a relatively thick magnetic sheet, it may be undesirable to make the magnetic layer 32 thick. Therefore, by interposing the spacer layer 33 between the magnetic layer 32 and the bottom surface 11, it is possible to secure a space of a height that makes it easy to insert a finger or fingernail while satisfying such a demand. The material of the spacer layer 33 is not particularly limited as long as it can be bonded to the adhesive layers 31 and 34. For example, it may be a resin (for example, a plastic made of a known thermosetting resin or thermoplastic resin, or a foamed plastic such as a soft polyurethane foam, a hard polyurethane foam, a polystyrene foam, a polyethylene foam, a polypropylene foam, an EVA crosslinked foam, a PET resin foam, or a phenol foam) or a metal (for example, aluminum, brass, stainless steel, carbon steel, titanium, copper, lead, etc.). In addition, the other adhesive layer 34 may be appropriately used as described for the adhesive layer 31. The adhesive layer 31 and the separate adhesive layer 34 may be the same or different.

Furthermore, from the viewpoint of ease of insertion of a finger or fingernail and control of the magnetic force, the thickness of the magnetic layer 32 is preferably 1 to 3 mm. And the thickness T2 of the support material 40 is preferably 5 to 15 mm. The thickness of the support material 40 here refers to the overall thickness T2 of the support material 40, that is, the total thickness of the support material 40 including the spacer layer 33 and the separate adhesive layer 34.

Furthermore, in the wiper dispensers 1, 2, 3, 4, 5, 6, and 7 according to the present embodiment described above, the shape of the bottom surface 11 and side wall 12 of the container body 10 may be such that a recess into which a finger can be inserted is provided at the peripheral edge. Specifically, the recess is provided at a part of the peripheral edge of the bottom surface 11 of the container body 10, at the peripheral edge where the bottom surface 11 and the side wall 12 meet, and is recessed from the bottom surface 11 toward the top surface when viewed from the side wall 12, and is recessed from the peripheral edge toward the center when viewed from the bottom surface 11.

This recess may be provided on at least a part of the periphery where the bottom surface 11 and the side wall 12 meet, but may also be provided on the entire width of the side wall 12 from one end to the other on which the recess is provided. By providing such a recess, the user can hook their fingers on the recess from the outside, making it even easier to remove from the installation surface 210. Although not particularly limited, the recess may be provided in the area of the periphery where the support materials 30, 40 are arranged, or in the area where the support materials 30, 40 are not arranged.

Further variations are described below.

Figures 10(A) and (B) are drawings of the container body of a wiper dispenser according to the eighth embodiment, where Figure 10(A) is a partial perspective view of the container body, and Figure 10(B) is a partial enlarged view of the container body. Figure 10(B) is a schematic cross-sectional view taken along line X-X in Figure 10(A).

As shown in FIG. 10, the container body 50 preferably has at least one recess 53 recessed toward the bottom surface 11 and the side wall 12 on the periphery 51 where the bottom surface 11 and the side wall 12 meet. The recess 53 is formed on the periphery 51 where the bottom surface 11 and the side wall 12 meet, and is recessed from the bottom surface 11 toward the top surface (not shown, above the drawing in FIG. 10) when viewed from the side wall 12, and is recessed from the periphery 51 toward the center of the bottom surface 11 when viewed from the bottom surface 11. These recessed structures may be rectangular or have a concave curved shape, but are preferably structures having a concave curved shape. With this structure, the fingers can be inserted smoothly without hurting the fingers on the sharp corners of the curved surface. By providing such a recess 53, the user can hook his/her fingers on the recess 53 from the outside (see arrow F4), making it easier to lift the container.

Moreover, it is more preferable that the area of the recess 53 farthest from the side wall 12 and closest to the center is deeper than the other areas of the recess 53 from the bottom surface 11 toward the top surface (not shown, toward the top of the drawing in FIG. 10). With this structure, the inserted finger can be hooked deeply into the center of the recess 53, making it easier to lift it stably.

The recesses 53 can be provided, for example, on the periphery where the bottom surface 11 and side wall 12 of the container body 10 of the wiper dispensers 1, 2, 3, 4, 5, 6, and 7 according to the first to seventh embodiments described above. The dimensions, shape, number, and location of the recesses 53 can be determined taking into consideration the dimensions and shape of the wiper dispensers 1, 2, 3, 4, 5, 6, and 7, and the dimensions and shapes of each member constituting the support material. The recesses 53 are preferably provided in a non-contact area where the supports 30 and 40 are not present. With this structure, the recesses 53 become deeper by the thickness of the supports 30 and 40, making it easier to insert a finger.

The number of recesses 53 should be at least one, and is preferably two or more. Furthermore, when two or more recesses 53, 54 are provided, it is preferable to provide the recesses 53, 54 on one periphery 51 and the opposite periphery 52, respectively, when viewed from the bottom of the container body 50. Specifically, it is more preferable that the container body 50 has at least one recess 53 provided on one periphery 51 and at least one recess 54 provided on the opposite periphery 52, when viewed from the bottom, and that the recesses 53 and 54 are arranged opposite each other. By arranging the two recesses 53, 54 opposite each other, fingers can be inserted from both the left and right sides (see arrow F4), making it easier to lift the container.

From this viewpoint, it is preferable that the recesses 53, 54 are provided symmetrically on the left and right, up and down, or up and down and left and right on the bottom surface of the dispenser. In order to insert fingers into the recesses 53, 54 to lift the dispenser, two or more recesses 53, 54 may be provided along any same side (same periphery) constituting the four periphery of the bottom surface 11, spaced apart by a size that allows fingers to fit. For example, as shown in FIG. 10, two or more (e.g., three) recesses 53 can be provided in series on one periphery 51. The same number (e.g., three) of recesses 54 can also be provided in series on the periphery 52 opposite the periphery 51. In this case, the recesses 53, 54 that are provided in series may be arranged so that a part of each recess is connected to each other. By connecting the recesses 53 and 54 without providing a gap, the recesses 53, 54 can be inserted while the fingers of the hand are in contact (for example, the three fingers from the index finger to the ring finger of the same hand are in contact), making it easier to lift the dispenser. In any of the above embodiments, it goes without saying that the dimensions of the width, height, and depth of the recess into which the finger is inserted can be selected as appropriate.

Figure 11 is a partial perspective view of the container body of a wiper dispenser according to a ninth embodiment.

The container body 60 shown in FIG. 11 has a recess 63 formed on the periphery 61 where the bottom surface 11 and side wall 12 meet, the recess 63 being recessed toward the bottom surface 11 and side wall 12. When viewed from the side wall 12, the recess 63 is recessed from the bottom surface 11 toward the top surface (not shown, above the drawing in FIG. 11), and when viewed from the bottom surface 11, the recess 63 is recessed from the periphery 61 toward the center of the bottom surface 11. However, compared to the recesses 53 and 54 shown in FIG. 10, the recess 63 is wider. Similarly, a recess 64 is provided on the other periphery 62 that faces the periphery 61, so as to face the recess 63.

The recesses 63, 64 have such a wide concave shape that two or more fingers can be inserted into the recesses 63, 64. As a result, the fingers do not slip when removing the wiper dispenser because they are not pinched between the non-recessed parts, and the wiper dispenser can be removed stably.

From this perspective, it is preferable that the distance of the recesses 63, 64 on the periphery 61, 62 is 1/4 to 2/3 of the length (side length) of the periphery 61, 62 on which they are provided. It is more preferable that the lower limit of this ratio is 1/3 or more. It is also more preferable that the upper limit of this ratio is 1/2 or less. By making the recesses 63, 64 wider with such ratios, the above-mentioned advantage of being able to remove the cover stably without fingers slipping is further improved.

As described above, the wiper dispensers 1, 2, 3, 4, 5, 6, and 7 according to this embodiment have at least the advantage that they do not shift position when in use and are easy to remove from the installation surface 210 and carry. Therefore, they are suitable, for example, as commercial wiper dispensers that are frequently used by many users.

Commercial wiper dispensers are used in places such as medical facilities, laboratories, precision parts factories, food processing factories, school lunch centers, and restaurants, where a large number of wipers W are used repeatedly. This makes it easy for problems such as the above-mentioned misalignment during use and even falling off the installation stand 200 to occur. However, this embodiment is particularly suitable because it can prevent such misalignment and is easy to remove from the installation surface 210 and carry.

<How to install a wiper dispenser>

According to this embodiment, for example, a method for installing an existing wiper dispenser 100 that does not include the support material 30, 40 can also be provided using the support material 30, 40. For example, the installation method for the wiper dispenser 100 according to this embodiment is a method for installing a wiper dispenser 100 that includes a resin or metal container body 10, 50, 60 having at least a substantially rectangular bottom surface 11 and a side wall 12 erected from the bottom surface 11, and a first lid body 20 that can close an opening 13 formed by the side wall 12 of the container body 10, 50, 60, and stores a wiper W in the container body 10, 50, 60, and includes the following steps.

(1) a preparation step of preparing a support material 30, 40 including an adhesive layer 31 and a magnetic layer 32 including an anisotropic magnet and having a thickness of 1 to 3 mm laminated on the surface of the adhesive layer 31;
(2) a bonding step of bonding the support material 30 to the wiper dispenser 100 such that the adhesive layer 31 of the support material 30, 40 is bonded to the outer surface of the bottom surface 11 of the wiper dispenser 100;
(3) An installation step of installing the wiper dispenser 100 on the installation stand 200 so that the magnetic layer 32 of the support material 30, 40 contacts the installation stand 200 of the wiper dispenser 100.

Then, (3) the bonding process divides the outer surface of the bottom surface 11 of the wiper dispenser 100 into m equal-spaced sections in a first direction (m is an integer between 3 and 40) and into n equal-spaced sections in a second direction perpendicular to the first direction (n is an integer between 3 and 40), so that when the outer surface is divided into a plurality of sections, the non-bonded regions S2 to which the adhesive layer 31 is not bonded include at least the peripheral sections that are in contact with the periphery of the outer surface.

The installation method according to this embodiment can also be implemented by, for example, using a conventional wiper dispenser 100 as shown in Figures 12 and 13, and adhering the support materials 30, 40 to the outer surface of the bottom surface 11. In this way, the installation method according to this embodiment has the advantage of being highly versatile in that it does not shift position during use, and can be easily removed from the installation stand 200 and carried, even with an existing commercially available wiper dispenser 100.

The present invention will be described in more detail with reference to the following examples and comparative examples, but the present invention is not limited to these examples in any way.

Example 1
The wiper dispenser 1 shown in Figures 1 and 2 was produced. The support material 30 was placed on the bottom surface 11 of the container body 10, and a rectangular support (110 mm long, 175 mm wide) conforming to Figure 3 was placed at 81% of the center in the vertical direction and 83% of the center in the width direction of the dispenser bottom surface (135 mm long, 210 mm wide). The bottom surface 11 of the wiper dispenser 1 was rectangular, and was divided into 11 vertical divisions (n = 11, y1 to y11) and 12 horizontal divisions (m = 12, x1 to x12) to form unit sections, and the area was divided into 132 unit sections.

The materials used are as follows:
As the container body 10 and the first lid body 20, an existing wiper dispenser 100 (length 156 mm, width 226 mm, height 113 mm, container body 10 made of polypropylene, first lid body 20 made of polypropylene) shown in Figures 12 and 13 was used.
The adhesive layer 31 was a double-sided adhesive sheet (thickness of adhesive layer 31: 16 μm) in which adhesive layers were formed by applying an acrylic adhesive to both sides of a nonwoven fabric (pulp-based nonwoven fabric).
The magnetic layer 32 was an anisotropic ferrite rubber sheet (single-sided magnetized type, magnetic force: 88 g/cm ² , magnetization pitch: 3 mm, thickness of magnetic layer 32: 1 mm) in which an anisotropic ferrite magnet was mixed with nitrile rubber as a binder.
The thickness T1 of the support material 30 was 1.016 mm.

Example 2
The wiper dispenser 1 is the same as that of Example 1, except that a 3 mm-thick anisotropic ferrite-based rubber sheet (single-sided magnetized type, magnetic force: 145 g/cm ² , magnetization pitch: 5 mm, thickness of magnetic layer 32: 3 mm) is used as the magnetic layer 32.
The thickness T1 of the support material 30 was 3.016 mm.

Example 3
The wiper dispenser 1 is the same as that of Example 1, except that a 5 mm-thick anisotropic ferrite rubber sheet (single-sided magnetized type, magnetic force: 1180 g/cm ² , magnetization pitch: 5 mm, thickness of magnetic layer 32: 5 mm) is used as the magnetic layer 32.
The thickness T1 of the support material 30 was 5.016 mm.

Example 4
The arrangement of the magnetic layer 32 is the same as that of the wiper dispenser 1 of Example 1, except that 12 partitions, (x1, y1), (x2, y1), (x1, y2), (x1, y11), (x2, y11), (x1, y10), (x12, y11), (x11, y11), (x12, y10), (x12, y1), (x12, y2), and (x11, y1), are added as arrangement areas of the support so that the arrangement of the magnetic layer 32 is a pattern similar to that of Figure 4.
The thickness T1 of the support material 30 was 1.016 mm.

Example 5
The wiper dispenser 1 is the same as that of Example 4, except that a 3 mm-thick anisotropic ferrite-based rubber sheet (single-sided magnetized type, magnetic force: 145 g/cm ² , magnetization pitch: 5 mm, thickness of magnetic layer 32: 3 mm) is used as the magnetic layer 32.
The thickness T1 of the support material 30 was 3.016 mm.

(Comparative Example 1)
A wiper dispenser 100 shown in Fig. 12 and Fig. 13 was used. The wiper dispenser 100 was the same as the wiper dispenser 1 of Example 1 except that it did not include the support material 30.

(Comparative Example 2)
The magnetic layer 32 is the same as the wiper dispenser 1 of Example 1, except that an isotropic ferrite rubber sheet (single-sided magnetized type, magnetic force: 47 g/ ^cm2 , thickness of magnetic layer 32: 1 mm) made by mixing an isotropic ferrite magnet with nitrile rubber as a binder is used.

(Comparative Example 3)
This is the same as the wiper dispenser 1 of Comparative Example 2, except that the magnetic layer 32 is disposed on the entire front outer surface of the container body.

(evaluation)

(1) Evaluation of positional deviation from the installation surface 210: See Table 1

The wiper dispenser 100 was placed on a horizontally placed magnetic table (a desk manufactured by Okamura Corporation, product code DS165P MB41) so that the magnetic layer 32 was in contact with the table, and nonwoven fabric (100 sheets of Higene (trademark) Blue Handy Wipes manufactured by Nippon Paper Crecia Co., Ltd., mass of 100 sheets is 200 g) was placed inside the wiper dispenser 100, and the first lid 20 was closed, while the second lid 24 was left open and not closed.

Next, the first sheet is pulled out through the removal opening 23 provided in the first lid 20. In this state, 10 workers pulled out the sheet in the lengthwise or widthwise direction of the dispenser, diagonally upward at 45 degrees from the horizontal direction in which the dispenser was placed, and after each sheet was pulled out, the positional deviation from the installation surface 210 was evaluated by checking the average value of the maximum displacement (mm) before and after the movement of the four corners of the dispenser that had moved the most.

If the positional deviation was less than 5 mm, it was evaluated as "○", if it was 5 mm or more but less than 20 mm, it was evaluated as "△", and if it was 20 mm or more, it was evaluated as "×". The direction in which the wiper W was pulled out was the vertical direction along the pull-out direction of the pop-up type sheet stack, and the horizontal direction perpendicular to the pull-out direction. The results of the wiper W in a dry state without applying any chemical solution are shown below, but the evaluation results were the same even when the wiper W (100 sheets of Higene (trademark) Blue Handy Wipers, manufactured by Nippon Paper Crecia Co., Ltd., mass of 100 sheets is 200 g) was applied with 800 g of chemical solution (manufactured by Niitaka Co., Ltd., product name: food additive ethanol preparation Safecall 58S) and the attachment described in Patent Document 2 was attached with double-sided tape to the side of the removal port facing the wiper. The composition of the Safecall 58S drug solution is 50.18% by mass ethanol, 0.35% by mass DL-malic acid, 0.30% by mass glycerin fatty acid ester, 0.06% by mass sodium DL-malate, and 49.11% by mass purified water. The dimensions of the attachment are 55 mm in length, 130 mm in width, and 1 mm in thickness, made of polypropylene, with the line width extending vertically and horizontally of the cross being 0.7 cm, the length of the vertical lines of the cross being 2.5 cm, and the length of the horizontal lines of the cross being 4 cm.

(2) Evaluation of removal from installation surface 210 and carrying: See Table 2

The wiper dispenser 100 was placed on the vertically placed iron plate surface so that the magnetic layer 32 of the wiper dispenser 100 was in contact with it, and the nonwoven fabric was placed inside the wiper dispenser 100, occupying the first lid 20 and the second lid 24. Next, the ease of removing the dispenser from the installation surface 210 and carrying it was evaluated by evaluating it on a three-level scale when 10 workers (workers whose length from the yellow line of the nail to the tip of the nail was in the range of 0.5 mm to 2.0 mm) inserted their nails or fingers between the support material and the iron plate to remove the dispenser vertically from the iron plate.

If it was easy to remove, it was rated as "◎", if it was difficult to remove, it was rated as "○", and if it could not be removed, it was rated as "△". If there were different evaluation results among the 10 people, "◎" was rated as 3, "○" was rated as 2 and "△" was rated as 1, the total for all 10 people was calculated, and this value was divided by the 10 people to find the average, and when rounded off to the nearest whole number, the one digit of the most similar number was represented as "◎", "○", or "△" and this was the evaluation result.

In Example 1, the adhesive force of the adhesive layer 31 is stronger than the magnetic force of the magnetic layer 32, and when removing the wiper dispenser 1 from the installation surface 210, the adhesive surface between the bottom surface 11 of the container body 10 and the adhesive layer 31, or the adhesive surface between the magnetic layer 32 and the adhesive layer 31, does not peel off, and the magnetic layer 32 can be easily removed from the installation surface 210.

(1) The evaluation results of the positional deviation when the sheet was pulled vertically toward the dispenser at a 45-degree angle upward were "○" for Examples 1 and 2, "×" for Comparative Example 1, and "△" for Comparative Example 2. On the other hand, the evaluation results of the positional deviation when the sheet was pulled horizontally toward the dispenser at a 45-degree angle upward were "△" for Example 1, "○" for Example 2, and "×" for Comparative Examples 1 and 2. Since the take-out port 23 in FIG. 12 has an elliptical shape that is long in the horizontal direction, the result of (1) showed that the amount of movement was greater when the sheet was pulled horizontally at a 45-degree angle upward than when the sheet was pulled vertically at a 45-degree angle upward. This is thought to be because the sheet formed wrinkles and gathered in the narrow areas at both ends of the width direction of the elliptical take-out port, increasing the take-out resistance. In Comparative Example 1, the evaluation was "×" because no space was secured for inserting a finger or nail.

(2) The evaluation results of removal and carrying of the dispenser from the installation surface 210 for Examples 1 to 3 were "good" or "excellent" for removal and carrying up to 3 mm in thickness for Example 2, and "good" for removal and carrying when the thickness was 5 mm or more. Furthermore, when the hands or nails were wet, the inserted finger or finger was easily slippery, so Examples 1 and 2 were "good". And, in Examples 4 and 5, in which the magnets were arranged according to FIG. 4, even if the inserted finger or nail slipped sideways in the inserted space, the magnets arranged in the peripheral section acted as a stopper, so even if it slipped, it was possible to suppress the slippage, and it was "good". On the other hand, in Comparative Example 3, it was "good" in both the dry and wet states. Note that the evaluation of the positional deviation for all of Examples 1 to 5 was good. That is, in Examples 1 to 5, the positional deviation during use was sufficiently prevented, and as described above, the evaluation of the removal and carrying was also good.

From the above, it has been confirmed that the wiper dispenser and the installation method of this embodiment do not shift position during use, and are easy to remove from the installation surface and to carry around.
