In addition, there is a problem that it takes a long time to apply a large area of the coating, it is hard work, coating efficiency is low, and coating unevenness easily occurs. On the other hand, the method of supplying paint to the roller by the conduit used in the paint applicator makes it difficult to supply the liquid uniformly to the sponge around the roller, and because the liquid is supplied from inside the roller, the amount of liquid is large. In particular, in the case of a chemical solution having a relatively low viscosity, there is a problem that it is easy to drop and dripping, and it is difficult to apply. It is not economical because the amount of liquid used increases.

Accordingly, a basic object of the present invention is a roller-type applicator capable of applying a large area with good workability in one application operation, and is made of an elastic porous material of a cylindrical application roller.

[0009]

[Embodiment of the invention]

 The basic features of the roller-type foamed chemical liquid applicator according to the present invention include a cylindrical application roller having an application portion made of an elastic porous material on the outer peripheral portion, and a bubble reservoir cover having an internal space having a substantially semicircular cross section. The liquid medicine is rotatably mounted in the member, and supplies the chemical solution in the form of foam to a bubble reservoir space formed by a gap between the inner peripheral surface of the foam reservoir cover member and the outer peripheral surface of the cylindrical application roller. And to impregnate and impregnate the coating section of the roller. Since the chemical is foamy, it does not drip or drip and can be applied evenly with a small amount of liquid thinly and evenly, which is economical. It can be applied with good workability.

[0010] In order to supply the chemical solution in the form of foam as described above, in the applicator of the present invention, the chemical solution supply path (foam outlet) of the foam generating nozzle attached to the upper end of the hollow handle portion stores the foam. It has a structure in which the upper end of a chemical solution supply pipe extending into the hollow handle is connected to the chemical solution supply passage of the foam generating nozzle, which communicates with the internal space of the cover member. Therefore, when the body of the container is squeezed with the lower end of the chemical solution supply pipe inserted into the chemical solution container and the mounting portion at the lower end of the hollow handle fixed to the container mouth, the chemical solution vigorously flows in the chemical solution supply tube. The chemical liquid flows and jets out from the chemical supply path of the bubble generation nozzle. At this time, the air is entrained through the small air inlet hole communicating with the chemical supply path, so that the chemical liquid jets out in the form of foam. It is supplied to the bubble reservoir space between the inner surface of the reservoir cover member and the cylindrical application roller. At this time, at a predetermined location on the inner peripheral portion of the foam reservoir cover member, a foam reservoir chamber that is communicated with the chemical solution supply path of the foam generating nozzle and that is defined by a peripheral wall having a plurality of holes in a side wall portion is formed. For example, the foamed chemical solution ejected from the foam generation nozzle once fills the foam reservoir, and then ejects from several holes provided in the foam reservoir, so that the cylindrical coating roller is rotated. It can be uniformly adhered to the outer peripheral application portion. It is also advantageous in that the scattering of the chemical solution can be completely prevented.

[0011] In this specification, the effervescent chemical liquid means a chemical liquid capable of generating bubbles when air is mixed therein, and any application for applying such a chemical liquid is applicable to all uses. The applicator of the present invention can be used. In addition, even if the liquid has a low viscosity and is unlikely to generate bubbles, it can be applied by, for example, adding a surfactant to easily generate bubbles. As described above, the applicator of the present invention does not use a propellant gas to generate the foam of the chemical solution, and since it is of the application type, there is no danger of the chemical solution being scattered, and the safety is improved. Excellent. Therefore, it can be suitably used for application of a chemical solution that needs to avoid inhalation and contact, in particular, a mold removing agent. Other features and aspects of the present invention will be described together with the embodiments shown in the accompanying drawings.

[0012]

【Example】

 FIG. 1 schematically shows the entire configuration of an embodiment of the roller-type foamed chemical liquid applicator of the present invention. In the figure, reference numeral 1 denotes a container for accommodating a foaming chemical liquid 2, and 10 denotes a container. The hollow handle portion, 20 is a foam generating nozzle attached to the upper end of the hollow handle portion 10, 30 is a chemical solution supply pipe whose upper end is connected to the foam generating nozzle 20, and 40 is air intake with a check valve. The mouth, 50 is a bubble reservoir cover member attached to the upper end of the hollow handle portion 10, 60 is a cylindrical application roller rotatably mounted inside the bubble reservoir cover member 50, and 70 is disposed in the container 1. It is the chemical | medical solution backflow prevention cylinder which was done.

The chemical liquid backflow prevention cylinder 70 disposed in the container 1 has a length that reaches the bottom from the edge of the mouth of the container 1, and the upper end has a hole into which the chemical liquid supply pipe 30 is inserted. It is closed by a shielding plate 71 on which 72 is formed. On the other hand, the lower end of the chemical liquid backflow prevention cylinder 70 is open, and the opening edge is formed in a waveform, and the chemical liquid 2 can enter and exit through the concave portion 73 of the waveform. Further, the chemical liquid backflow prevention cylinder 70 has an outer diameter equal to the inner diameter of the mouth 3 of the container 1. On the other hand, the hollow handle 10 has an inner diameter slightly smaller than or approximately equal to the outer diameter of the chemical liquid backflow prevention cylinder 70, and has a lower end formed with an external thread formed on the outer periphery of the mouth 3 of the container 1. A female screw part screwed with the part has a large-diameter mounting part 11 formed on the inner peripheral surface.

Therefore, when the chemical liquid backflow prevention cylinder 70 is inserted from the mouth 3 of the container 1 and the mounting portion 11 of the hollow handle 10 is screwed into the mouth 3 of the container 1, as shown in FIG. The backflow prevention cylinder 70 is fixed in the container 1 in a state where the upper end edge thereof is pressed by the base step 12 of the attachment part 11 of the hollow handle 10. As a result, communication between the space in the container 1 and the space in the hollow handle 10 is blocked by the shielding plate 71 at the upper end of the chemical liquid backflow prevention cylinder 70. Even if the container 1 is inverted, the chemical liquid 2 in the container 1 is hollow. It does not flow into the handle 10. In addition, since the space in the container 1 is sealed by the chemical liquid backflow prevention cylinder 70 as described above, when the container 1 is squeezed, the chemical liquid 2 in the container 1 vigorously rises inside the chemical liquid supply pipe 30 and the upper end thereof It is ejected from the bubble generation nozzle 20 to which the section is connected.

A bubble generating nozzle 20 is attached to the upper end of the hollow handle 10 as shown in FIGS. The bubble generating nozzle 20 has a large-diameter cylindrical portion 21 and a small-diameter cylindrical portion 22 protruding downward from a central portion, and a through-hole in these cylindrical portions forms a chemical solution supply path 23. A plurality of (six in the illustrated example) slits 24 are formed in the stepped portion between the large-diameter cylindrical portion 21 and the small-diameter cylindrical portion 22 as shown in FIG. Since it is slightly larger than the outer diameter of the portion 22, a minute air inflow hole 25 is formed in the slit forming portion. Therefore, the chemical liquid that vigorously rises in the chemical liquid supply pipe 30 whose upper end is joined to the small-diameter cylindrical part 22 moves the ball 27 accommodated in the space (mixing chamber 26) in the large-diameter cylindrical part 21. When the liquid is pushed up and flows into the mixing chamber 26, air also flows in as fine bubbles from the minute air inflow holes 25 of the slit 24, and the liquid medicine and air bubbles are mixed in the mixing chamber 26 to form a foamy liquid medicine. It is ejected from the ejection port 53. The ball 27 functions as a check valve for preventing the foamed chemical liquid once ejected from flowing down into the chemical liquid supply pipe 30, but also has a function as a stirring member at the time of the gas-liquid mixing. . A net or a perforated plate 28 is arranged on the upper part of the large-diameter cylindrical portion 21 and is fixed by a cylindrical pressing member 29 so that the ball 27 does not fly out of the ejection port 53 when the foamed chemical solution is ejected. ing.

When the space in the hollow handle 10 is sealed, the air in the hollow handle 10 is sucked into the mixing chamber 26 from the air inlet 25 when the foamed chemical solution is ejected. It is preferable that the space in the hollow handle 10 be in communication with the atmosphere because the pressure in the space is slightly reduced and the suction of air becomes worse. For this purpose, a part of the foam generating nozzle 20 is formed with an air inlet 40 with a check valve communicating with the outside. The air inlet 40 with a check valve is composed of a vertical through hole 41 and a ball 42 housed therein, and a chemical solution enters the hollow handle 10 when the applicator is turned upside down. Even if it is, the ball 42 closes the hole 54 formed at a position aligned with the through hole 41 of the bubble reservoir cover member 50, so that liquid leakage is prevented. When the chemical liquid 2 in the container 1 is completely prevented from flowing into the hollow handle 10 by the chemical liquid backflow prevention cylinder 70 as described above, for example, the liquid A space inside the hollow handle 10 may be communicated with the outside by forming a hole having a large size.

FIG. 4 shows the bubble reservoir cover member 50 and a tubular coating roller 60 rotatably mounted inside the bubble reservoir cover member 50. The bubble reservoir cover member 50 includes a semicircular side wall portion 51 and side plate portions 52 integrally formed at both ends thereof. As shown in FIGS. 1 and 4, one side of the side wall portion 51 is so formed that the surface of the opening portion is inclined at a predetermined angle with respect to the axial direction of the hollow handle portion 10 as shown in FIGS. It is fixed to the upper end of the hollow handle 10 and the upper surface of the bubble generating nozzle 20 at a position in the center in the longitudinal direction near the portion. A spout 53 is formed at the position of the side wall 51 aligned with the chemical solution supply passage 23 of the foam generating nozzle 20, and a hole 54 is formed at a position aligned with the air intake 40 with a check valve. A peripheral wall 56 having a semicircular cross section that defines a bubble reservoir chamber 55 that communicates with the ejection port 53 is provided at a predetermined position in the lower portion of the inner peripheral portion of the side wall portion 51. The peripheral wall 56 is set at a height such that the peripheral wall 56 comes into contact with the application portion 62 of the cylindrical application roller 60 or a small gap is formed between the peripheral wall 56 and the inner peripheral surface of the bubble reservoir cover member 50. A plurality of (four in the illustrated example) holes (bubble ejection holes) 57 are provided on the wall facing the center of the bubble reservoir space 58 formed by a gap between the outer peripheral surface of the roller 60 and the outer peripheral surface. Are formed.

On the other hand, the cylindrical application roller 60 is composed of a cylindrical body 61 and an application part 62 made of an elastic porous material wound around the outer periphery thereof. As shown in FIG. 1, the inside of the cylindrical body 61 is divided into three hollow chambers, and when the coating part 62 to which the foamed chemical liquid is attached and impregnated is applied while being pressed against the surface to be coated. Then, the excessively impregnated chemical solution is temporarily held in each hollow chamber, and then shifts when the amount of the chemical solution on the surface of the coating section 62 becomes small, and the chemical solution is efficiently and uniformly distributed without dripping or the like. Although it is devised so that it can be applied to the surface, it goes without saying that it may be formed into a simple cylindrical body. The coating portion 62 can be made of an elastic porous material such as various synthetic resin foams, rubber foams, felts, etc., but particularly from the viewpoints of chemical resistance, durability, chemical solution retention, etc., a polypropylene resin or a polyethylene resin. Open-celled bodies of a polyolefin resin such as are preferred.

The cylindrical application roller 60 is formed by fitting both ends of a cylindrical body 61 into a circular concave fixing portion 59 formed at the center of the inner surface of both side plates 52 of the bubble reservoir cover member 50. It is attached. The tubular application roller 60 mounted on the bubble reservoir cover member 50 in this manner is rotatable in both directions, but it is preferable to use it while rotating in the direction indicated by the arrow in FIG. . The foamed chemical liquid ejected from the foam generation nozzle 20 by squeezing the container 1 once fills the foam storage chamber 55, and then through a plurality of holes 57 formed in the peripheral wall 56 through the bubble storage space. It spouts into 58 and is stored there. The foamed chemical liquid in the bubble reservoir space 58 continuously adheres to and impregnates the coating portion 62 made of the elastic porous material as the cylindrical coating roller 60 rotates in the direction of the arrow. The amount of the adhering liquid 62 is regulated by the peripheral wall 56 of the bubble reservoir 55, and is uniformly applied. Therefore, by performing the coating operation while pressing and rotating the cylindrical coating roller 60 against the surface to be coated, the chemical solution can be thinly and evenly applied. At this time, if the foam reservoir cover member is transparent or translucent and is made of a material that allows visual confirmation of the bubble accumulation state, for example, if it is made of a transparent or translucent plastic material, the coating operation is performed while confirming the bubble accumulation state. This makes it easy to judge the next squeeze time of the container, making the work easier.

FIG. 5 shows another embodiment of the chemical liquid backflow prevention means. This chemical liquid backflow prevention member 70a is formed of a disk having a hole 72 having a diameter equal to the outer diameter of the chemical liquid supply pipe 30 formed at the center thereof, and the outer diameter of the disk is substantially equal to the outer diameter of the mouth 3 of the container 1. equal. The chemical liquid supply pipe 30 is fitted into the hole 72 of the disc-shaped chemical liquid backflow prevention member 70a and placed on the mouth end of the container 1 with the chemical liquid supply pipe 30 inserted therein, and the mounting portion 11 of the hollow handle 10 is attached to the mouth 3 of the container 1. When screwed together, the chemical liquid backflow prevention member 70a is fixed so as to be sandwiched between the mounting portion 11 and the mouth 3 of the container 1, and communication between the space in the container 1 and the space in the hollow handle 10 is cut off. In this embodiment, the length of the flexible chemical supply pipe 30 is such that the tip thereof reaches the bottom peripheral edge of the container 1, but the remaining amount of the chemical in the container is as small as possible. Any length is acceptable as long as it can be supplied.

[0021]

[Effect of the invention]

 As described above, the roller-type foam-type chemical liquid applicator of the present invention foams the chemical liquid and supplies it to the application part of the cylindrical application roller, where it is adhered and impregnated, so that dripping or dripping may occur. It is economical because it can be applied thinly and evenly with a small amount of chemical solution, and the application part is a roller type, so that it can be applied to a wide area without unevenness in a short time with good workability. In addition, the chemical solution can be supplied only by squeezing the container, which is easy to use and uses no propellant gas, so there is no danger and it can be used safely. In addition, by providing a bubble reservoir inside the bubble reservoir cover member so as to cover the injection port, it is possible to more reliably prevent the chemical solution from scattering, and whether the peripheral wall of the bubble reservoir is in contact with the application portion of the cylindrical application roller. Alternatively, by setting the height such that a slight gap is formed, the foamed chemical liquid can be more uniformly adhered to the application portion of the cylindrical application roller. Furthermore, by providing a chemical liquid backflow prevention means between the container and the hollow handle, the chemical in the container leaks out through the hollow handle even when the applicator is turned upside down or placed sideways. It can be reliably prevented from coming out. The roller-type foamed chemical liquid applicator of the present invention can be used for applying various chemical liquids such as a cleaning liquid and a mold removing liquid.However, since it is excellent in safety, it can be suitably used especially as a mold removing agent applying tool. It is advantageous in that it can be easily applied in a short time without unevenness over a large area as compared with the trigger type, which is the mainstream of conventional mold remover products. In addition, since the amount of the mold remover used is small, rinsing after the application operation is easy, and the chlorine odor is weak and the operation is easy. In addition, there is little danger that the fungicide will be scattered because of the foam type.
