Description

  The present invention relates to an application body used when an application agent such as a paint is applied to an object having a smooth surface such as glass, light metal, or hard synthetic resin.

  Conventionally, the term “painting” mainly applies to buildings such as floors and walls, furniture to be coated such as wood and iron plates such as furniture, and coating bodies such as brushes and rollers have been used.

  These conventionally used brushes and other applied bodies can hold a relatively large amount of coating agent and can be applied over a wide range at one time. However, a large amount of coating agent is applied to the surface to be coated. As a whole, it tends to become thicker or a spot like a brush eye.

  Therefore, recently, the application of coating agents such as paints has increased, and coating agents such as paints are very thin on a coated object having a smooth coated surface such as glass, light metal, and hard synthetic resin. It cannot be used when it is necessary to apply a uniform film.

 Therefore, as shown in FIG. 10, a rod-shaped grip 12 is protruded from a bowl-shaped applicator main body 11 so that a cloth-like applicator 13 is wound around the applicator main body 11 and attached to the applicator main body 11. The applicator 1 fixed by the engaging tool 14 like a hook-and-loop fastener is used.

  The applicator 13 used in the applicator 1 can be applied evenly and relatively uniformly compared to conventional applicators such as brushes.

  However, since the entire coated body 13 is formed of a piece of cloth, the amount of the coating agent to be retained is not sufficient, and the number of times the coating agent is retained in the middle increases. .

  In order to increase the holding amount of the coating agent, it is necessary to enlarge the volume of the coating body 13, and therefore, it is necessary to make the yarn constituting the cloth piece thick. For this reason, the weaves and stitches become large, resulting in variations in the amount of the coating agent detached, and the uniformity of the formed coated surface is impaired. Furthermore, since the application body 13 is formed of a piece of cloth, the elasticity is poor, the usability at the time of painting is poor, and the function is inferior.

  In order to solve the problem of the applicator shown in FIG. 10, Japanese Patent Application Laid-Open No. 2003-71369 discloses an application part made of ultrafine fibers on the surface of a holding part formed of a continuous foam such as urethane sponge. What you have is presented.

  The application body presented in this gazette soaks the application agent in the application part, quickly passes through the application part and is impregnated and held in the holding part, and holds when the application part is pressed against the surface of the object to be applied. Part of the coating agent is applied, a sufficient coating agent can be retained, and a relatively smooth coating surface can be obtained with a fine coating part.

  However, in the application body presented in the above publication, since the application part is formed of ultrafine fibers, even though the application part can be applied relatively smoothly, the holding part is not inherently hydrophilic and has water absorption and water retention. Since it is formed of a poor urethane sponge, it does not hold the coating agent sufficiently, and since it is relatively flexible, it is constant because a large amount of the applied coating agent is pushed out when pressed to apply thinly during painting. It is difficult to move the amount uniformly to the application part, and as a result, a uniform painted surface cannot be obtained.

In addition, the coating part is made of ultrafine fibers, so even if it can be applied relatively smoothly, paint or the like on a coated object having a smooth coated surface such as glass, light metal, hard synthetic resin, etc. It is difficult to apply the coating agent in the form of a film. In addition, since the coated surface is in close contact with the smooth coated surface, the contact resistance increases, and it is difficult to move and there is a problem in operability.
JP 2003-71369 A

  The problem to be solved by the present invention is that the conventional applicator can sufficiently hold a coating agent such as a paint and can coat a wide range of painted surfaces by a single holding operation. The present invention provides an applied body that can uniformly apply a coating agent such as a liquid paint to a coated object having a smooth coated surface such as a hard synthetic resin.

  The first invention made to solve the above-mentioned problems is a woven fabric or warp made of super-fine fibers of 0.3 denier or less on the surface of a holding part formed by laminating a woven or knitted fabric or nonwoven fabric made of ultra-fine fibers of 1 denier or less. The second invention is characterized by superfine fibers having a denier of 0.3 denier or less on the surface of the holding portion which is a polyvinyl alcohol-based or viscose-based foam. It is characterized by being formed by superimposing application portions made of woven fabric or warp knitted fabric.

  Further, it is more preferable that the application part superimposed on the holding part forms a continuous loop by fixing the wiping cloth with a slack allowance at predetermined intervals.

  According to the present invention, the fiber crossing and looping rules such as warp knitted fabrics, in which each warp yarn arranged in an orderly manner is formed in the same manner as a woven fabric or woven fabric of ultrafine fibers of 0.3 denier or less as an application portion. Since a very uniform and uniform gap with a uniform property is used, the retained coating agent can always be uniformly transferred to the coated surface having a smooth surface, and the smooth surface is bitten. Is very good and can be applied in the form of a thin film. Furthermore, fine dust and the like existing on the surface to be coated are also absorbed.

  In addition, since the holding portion is excellent in holding ability of 1 denier or less, that is, a laminate of woven fabric, knitted fabric, non-woven fabric, etc. having a high porosity, it is possible to hold a sufficient amount of coating agent uniformly as a whole. It can cope with a wide coated surface.

  Fabrics with super-fine fibers of 0.3 denier or less, or fabrics with regularity of the fiber crossing and loops, such as warp knitted fabrics, in which each warp arranged in an orderly manner is looped in the same way as a fabric As a result, the coating applied by the pressure applied at the time of application is joined and united and held in the holding part is uniformly transferred to the application part by the mutual capillary action, and the uniform application is continued over a wide area. Can do.

  In particular, since both the holding part and the application part are formed of fibers, they can be used regardless of aqueous or oily.

  Further, since the holding part can absorb and hold the coating agent, the coating amount can be adjusted, and an appropriate amount of the coating agent can always be applied to the object to be coated.

  Furthermore, in the second invention, when a polyvinyl alcohol-based or viscose-based foam is used as the holding portion, the water absorption, water retention, squeezability, strength, and body wear resistance are improved by being overlapped with the coating portion. Demonstrate. In particular, when the application part superimposed on the holding part forms a continuous loop by fixing the wiping cloth with a slack allowance at predetermined intervals, the application agent is absorbed and retained in the application part. Since it is possible to increase the capacity, not only can the workability be improved by applying the coating agent to the object to be coated in one operation, but also the coating surface where adjacent loops overlap each other during coating. Is formed, the frictional resistance generated between the coated surface and the coated surface in the case where no loop is formed is reduced, so that the movement is easy and the operability is excellent.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIGS. 1 and 2 show an embodiment in which the first invention is applied to an applicator 13 used for the applicator 1 similar to the conventional example shown in FIG. 5 has a width and length covering and covering the bowl-shaped applicator main body 11 shown in FIG. 5 to form a flat rectangular cloth shape. A plurality of eyes of a certain size can be formed uniformly by crossing the fibers on the surface of the holding part 2 formed by laminating one or a plurality of woven or knitted fabrics or non-woven fabrics of ultrafine fibers of 1 denier or less. The application portions 3 made of a woven fabric or warp knitted fabric of super-fine fibers of 0.3 denier or less are overlapped and integrally bonded around the periphery.

  According to the present embodiment, the holding portion 2 is formed by laminating a plurality of woven or knitted fabrics or non-woven fabrics made of ultrafine fibers having a denier of 1 denier or less, so that the amount of coating agent applied at one time is absorbed and held in a uniform state. In addition, it is possible to evenly replenish the coating part 3 with the held coating agent on the surface. In particular, the holding part 2 has moderate elasticity, and both the holding part 2 and the application part 3 are formed of fine fibers, so that a number of capillaries formed in the joining direction of both hold the pressing part during application. A suitable amount of the coating agent moves from the holding unit 2 to the coating unit 3 in a uniform state with the pressure.

  In addition, the application part 3 is a woven fabric or warp having regular and dense fiber intersections with ultrafine fibers of 0.3 denier or less that are thinner than those of conventional woven mesh or nonwoven fabric of 1 denier or less. Since it is made of woven or knitted fabric, a smooth coated surface such as glass also has an adsorption effect, and a thin and uniform coated surface can be formed.

  In addition, in this Embodiment, although the application part 3 was provided only in the single side | surface of the holding | maintenance part 2, you may provide in both surfaces.

  3 and 4 show an embodiment of the second invention. The purpose of use and the like are almost the same as those of the embodiment shown in FIGS. 1 and 2, but the holding portion 2 is made of polyvinyl alcohol. The difference is that it is a foam having a thickness of up to about 10 mm and a coating part 3 is disposed on both sides of the holding part 2.

  According to the present embodiment, the polyvinyl alcohol-based or viscose-based foam is hydrophilic, excellent in water retention, has moderate elasticity, and has microscopic pores. Similar to the woven mesh and non-woven fabrics, the coating part 3 is made of a woven or warp knitted fabric having regular and dense fiber intersections with super fine fibers of 0.3 denier or less. And fuse in terms of functionality.

  Polyvinyl alcohol-based or viscose-based foams have poor water absorption when fitted, but they exhibit very good water absorption once wetted, which is particularly problematic in terms of painting work. Never become.

  Polyvinyl alcohol-based or viscose-based foams are significantly superior in terms of tear strength, body wear, water absorption rate, maximum water retention rate, etc. compared to woven or non-woven fabrics or rubber sponges made of ultrafine fibers. Therefore, it is excellent in workability and durability.

  FIG. 5 and FIG. 6 show still another embodiment of the first invention, in which the coated body 13 is a natural or synthetic conventionally known woven or knitted or non-woven fabric made of ultrafine fibers of 0.1 denier or less. A woven fabric made of ultra-fine fibers of 0.3 denier or less, in which a plurality of eyes having a certain size can be uniformly formed by crossing fibers on the surface of the holding part 2 formed by laminating one or a plurality of sheets The application portion 3 made of warp knitted fabric is overlapped and integrally bonded around the same as in the embodiment shown in FIG. 1 and FIG. The application unit 3 is different in that the wiping cloth is fixed with a slack allowance at predetermined intervals to form a continuous loop 31.

  The loop 31 is formed by fixing the wiping cloth with a slack allowance at predetermined intervals, for example, by sewing means, and the height and width of the loop are selected suitable for application. The width is preferably about 1 to 10 mm, and the width may have an attachment width that overlaps with the adjacent loops 31 when pressed against the substrate 8 and lying down.

  The present embodiment has the same operation and effect as the embodiment shown in FIGS. 1 and 2, but in particular, the application unit 3 has a slack allowance for the wipes at predetermined intervals. Since the adhering and adhering loop 31 is formed, the amount of the coating agent replenished from the holding unit 2 is larger than that of the embodiment shown in FIGS. A coating agent can be applied to the surface.

  Further, in the present embodiment, as shown in FIG. 7, in particular, a gap is generated when each adjacent loop 31 overlaps with each other adjacent loop 31 during application.

  Accordingly, the embodiment shown in FIGS. 1 and 2 is in close contact with the object to be coated, whereas in this embodiment, the edge shape formed by the fall of the loop 31 between the object 8 and the object to be coated. As a result, the friction between the coating portion 3 and the coated body 8 can be reduced and the smooth movement can be achieved. Since each edge passes sequentially, a uniform and thin coating film is formed, the finish is good, and the workability is excellent.

  In the present embodiment, the wiping cloth 32 part forming the loop 31 of the application part 3 is formed separately from the application part 3 part. However, as shown in FIG. 8, the wiping cloth 32 part forming the loop 31 is applied. It may be formed integrally with the portion 3, and in this case, it is economically advantageous because it requires less material and requires fewer manufacturing steps.

  In this embodiment, the holding unit 2 similar to that of the embodiment shown in FIGS. 1 and 2 is used. However, as the holding unit 2, the polyvinyl alcohol type or screw shown in FIGS. The same can be applied to the case of the second invention which is a foam having a course-like plate shape and a thickness of up to about 10 mm (not shown).

  Furthermore, since the present invention is formed of a fine porous body including the holding portion 2 in some cases, it may be difficult to hold the coating agent depending on the type of coating agent. FIG. 9 shows an embodiment of the means for holding the coating agent 4 used in such a case, and it is formed of fibers of, for example, about 1 denier or less in a container 5 containing the coating agent 4. The holder 2 according to the present invention, which is provided at the front end of the applicator 1 provided with a stamp base 6 using a woven or knitted fabric, a nonwoven fabric, or a polyvinyl alcohol-based or viscose-based foam, and inserted in the container 5 By applying an operation of pressing the application body 13 portion composed of the portion 3 against the stamp portion 7 to cause the holding portion 2 and the application portion 3 to perform a suction operation, the coating agent 4 can be easily and quickly applied to the application portion 3 and the holding portion 2. Can be retained.

  Furthermore, in the present embodiment, the case where the application body 13 used in the bowl-shaped applicator 1 shown in FIG. 10 is implemented is shown, for example, in the above-mentioned JP-A-2003-71369. Other types of applicators, such as those having a rectangular parallelepiped support, can be similarly implemented.
