Description

[Technical Field]

[0001] The present invention relates to a nozzle for applying various liquids such as detergents, fabric softeners, adhesives, and medicines, and an application tool including the nozzle. [Background technology]

[0002] Nozzles and application tools including nozzles for applying various liquids such as detergents, fabric softeners, adhesives, and medicines to objects are widely used.

[0003] For example, the nozzle disclosed in Patent Document 1 (JP 2012-045542 A) has a through hole that discharges liquid from the second side of the nozzle body, a plurality of first openings provided on the second side for discharging pressurized gas so as to be approximately tangent to the outer periphery of the liquid bead discharged from the through hole, thereby forming the liquid bead into a spiral discharge pattern of elongated liquid fibers, and a plurality of second openings on the second side that are positioned the same distance from the through hole as the plurality of first openings or closer to the through hole than the plurality of first openings, and that discharge pressurized gas parallel to the longitudinal axis 7 of the through hole around the spiral discharge pattern in order to suppress expansion of the diameter of the initial swirling spiral at an early stage in which the liquid fiber swirls.

[0004] [Patent Document 1] Patent Publication No. 2012-045542 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the nozzle disclosed in Patent Document 1 has a through hole that penetrates at approximately the central protrusion position and multiple other openings that penetrate at different positions to ensure a liquid passage, so it is not suitable for applying to objects with a relatively large area, and there is a risk that workability will actually be reduced.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an application nozzle and an application tool including the application nozzle that can perform application work reliably over a wide area with simple operation. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention a connection part that is attached to an opening of a container that stores a liquid; an application part that covers the connection part and has a discharge hole that discharges the liquid, the application part has, on an application surface thereof, a group of inner protrusions formed in a substantially radial pattern around the discharge hole, and a group of outer protrusions formed in a substantially radial pattern outside the group of inner protrusions; The present invention provides a coating nozzle characterized by the above.

[0008] In the application nozzle of the present invention, it is preferable that the group of inner projections and / or the group of outer projections are arranged at approximately equal intervals in the circumferential direction.

[0009] In the coating nozzle of the present invention, it is preferable that the projections constituting the inner projection group and / or the outer projection group have a length.

[0010] In the application nozzle of the present invention, it is desirable that the spacing between the inner projections in the circumferential direction is greater than the spacing between the outer projections in the circumferential direction.

[0011] In the application nozzle of the present invention, it is desirable that the radial length of the inner projection group is longer than the radial length of the outer projection group.

[0012] Furthermore, in the application nozzle of the present invention described above, it is desirable that the application surface includes a central portion where the group of inner protrusions is arranged and an outer surface where the outer peripheral portion is arranged, and that the outer peripheral portion is inclined with respect to the central portion.

[0013] The present invention also provides an application tool including any one of the application nozzles described above. [Effects of the Invention]

[0014] The application nozzle of the present invention allows for easy and reliable application over a wide area while distributing the liquid over a wide area using the inner projections, while the outer projections allow for localized application of the liquid over a relatively small area.

[Figure 4] 1 is a schematic diagram showing an example of how a liquid is applied to clothing 7 using an application tool 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] Representative embodiments of the application nozzle and application tool according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these drawings. Furthermore, since the drawings are intended to conceptually explain the present invention, dimensions, ratios, and numbers may be exaggerated or simplified as necessary to facilitate understanding.

[0017] In this embodiment, clothing 7 is used as an example of an object, detergent is used as an example of a liquid L to be applied, and the explanation is based on the assumption that the detergent is applied to the collar, sleeves, etc. of the clothing 7 using an application tool 1 (application nozzle 5).

[0018] However, the applicator 1 can also be applied to liquids L other than those mentioned above (for example, fabric softeners, adhesives, medicines, etc., or viscous fluids.) Furthermore, the objects to be applied are not limited to clothing 7, but broadly include cloth products such as towels, paper products, wooden products, resin products, and metal products.

[0019] 1. Application tools The applicator 1 will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing an overview of the applicator 1. As shown in Fig. 1, the applicator 1 is used to apply various liquids L (including viscous fluids) such as detergents, fabric softeners, adhesives, and medicines to an object.

[0020] The applicator 1 dispenses the stored liquid L onto an object and spreads the dispensed liquid L over the object, thereby distributing the liquid L to a desired position on the object. The applicator 1 includes a container 3 for storing the liquid L and an application nozzle 5.

[0021] The container 3 may be any type that can store the liquid L and to which the application nozzle 5 can be attached, but a bottle, for example, is suitable. The container 3 may be made of any material, such as a resin material or glass. The container 3 includes a peripheral wall and a bottom surface, and has an opening 31 (see FIG. 3(A)). The opening 31 and the application nozzle 5 may be covered with a cap (not shown).

[0022] 2. Application nozzle The coating nozzle 5 will be described in detail with reference to Fig. 2. Fig. 2 shows the structure of the coating nozzle 5.

[0023] The application nozzle 5 includes a connection part 51 that is attached to the opening 31 of the container 3, and an application part 52 that covers the connection part 51 and has a discharge hole 53. The application nozzle 5 may be produced as a single-piece molded product made of a resin material.

[0024] The connecting part 51 is fitted into the opening 31 of the container 3. More specifically, the connecting part 51 is substantially cylindrical, and the outer peripheral surface of the connecting part 51 comes into contact with the inner peripheral surface of the opening 31 of the container 3, thereby fixing the application nozzle 5 to the opening 31 of the container 3 (see FIG. 3(A)).

[0025] The outer diameter of the connecting part 51 may be gradually reduced towards the tip, which makes it possible to easily insert the tip of the connecting part 51 into the opening 31 of the container 3.

[0026] Applicator 52 is a substantially disc-shaped member that covers connecting portion 51 and bulges outward (toward the tip) (see FIGS. 2(B) and 2(D)). More specifically, applicator 52's surface (applicator surface 52A) may include a substantially circular, flat central portion 52B and an outer peripheral portion 52C that surrounds central portion 52B and is inclined relative to central portion 52B. The inclination angle θ of outer peripheral portion 52C relative to central portion 52B may be, for example, 30 to 45°, and preferably 35 to 45°.

[0027] The application part 52 extends radially outward beyond the connecting part 51. The outer edge of the application part 52 comes into contact with the tip of the opening 31 of the container 3, thereby preventing the application part 52 from entering the container 3 (see FIG. 3(B)).

[0028] A discharge hole 53 is formed in the central portion 52B of the application part 52. The discharge hole 53 is a passage for discharging the liquid L in the container 3 to the outside. The diameter of the discharge hole 53 may be set appropriately depending on the expected viscosity of the liquid L, but for example, in the case of a liquid detergent, it may be set in the range of 0.4 to 1.2 mm, and preferably in the range of 0.6 to 1.0 mm.

[0029] The application part 52 has, on the application surface 52A, a group of protrusions 54 (an inner group of protrusions) including a plurality of protrusions formed approximately radially around the discharge hole 53 (i.e., with the discharge hole 53 as the center), and a group of protrusions 55 (an outer group of protrusions) including a plurality of protrusions formed approximately radially outside the group of protrusions 54.

[0030] The projection group 54 is disposed in the central portion 52B of the application surface 52A. The height of each projection in the projection group 54 may be, for example, 0.3 to 0.7 mm, and preferably 0.4 to 0.6 mm. The radial length of each projection in the projection group 54 may be, for example, 2.0 to 6.0 mm, and preferably 3.0 to 5.0 mm. The individual protrusions of the protrusion group 54 may be arranged at approximately equal intervals in the circumferential direction. For example, the protrusion group 54 may be composed of six stripe-like protrusions arranged at intervals of approximately an angle α=45°.

[0031] Protrusion group 55 is arranged on outer circumferential portion 52C of application surface 52A. The height of each protrusion in protrusion group 55 may be roughly the same as or slightly lower than the height of each protrusion in protrusion group 54, for example, 0.1 to 0.5 mm, and preferably 0.2 to 0.4 mm. The radial length of each protrusion in protrusion group 55 may be, for example, 1.0 to 5.0 mm, and preferably 2.0 to 4.0 mm. The individual protrusions of the protrusion group 55 may be arranged at approximately equal intervals in the circumferential direction. For example, the protrusion group 55 may be composed of 24 stripe-like protrusions arranged at intervals of approximately angle β=15°.

[0032] That is, the circumferential spacing of the projection group 54 is preferably greater than the circumferential spacing of the projection group 55. Also, the radial length of the projection group 54 is preferably greater than the radial length of the projection group 55.

[0033] Therefore, when applicator part 52 slides over clothes 7, liquid L such as detergent discharged from discharge hole 53 onto clothes 7 is pushed out by projection group 54 and spreads over clothes 7. In other words, by using projection group 54, liquid L such as detergent can be dispersed over a wide area and reliably adhered to clothes 7.

[0034] Furthermore, by tilting the applicator 1 at approximately the angle β with respect to the clothes 7, the projections 55 (part of them) can be brought into contact with the clothes 7. In other words, by using the projections 55, the liquid L, such as detergent, can be applied to a relatively small area of ​​the clothes 7.

[0035] 3. How to use the application tool The method of using the applicator 1 will now be described.

[0036] First, a method for connecting the application nozzle 5 and the container 3 will be described with reference to Fig. 3. Fig. 3 shows a method for connecting the application nozzle 5 and the container 3. Liquid L (detergent in this embodiment) is poured into container 3, and connection part 51 of application nozzle 5 is inserted into opening 31 of container 3. Application nozzle 5 is pressed toward container 3, and the outer edge of application part 52 comes into contact with the tip of opening 31. In this way, application tool 1 can be constructed.

[0037] A method for applying liquid L to clothes 7 using the applicator 1 will be described with reference to Fig. 4. Fig. 4 shows how liquid L is applied to clothes 7 using the applicator 1. The collar or sleeve of the garment 7 is spread out on a flat surface. The application part 52 of the application tool 1 is brought close to the garment 7, and the liquid L is dispensed from the application part 52 by, for example, pressing the circumferential surface of the container 3 with a hand. The user may dispense the liquid L onto the application surface 52A, or may immediately drip the liquid L onto the garment 7.

[0038] Then, by bringing the applicator part 52 into contact with the clothing 7 and moving the applicator 1 in the desired direction (for example, toward the collar) while appropriately pressing the side of the container 3, the desired amount of liquid L can be applied to the desired area on the clothing 7. Furthermore, by appropriately using the projection groups 54 and 55, it is possible to spread the liquid L over a relatively wide area of ​​the object, or to selectively apply the liquid L to a relatively narrow area.

[0039] Therefore, with the applicator 1 of this embodiment, the projections 54 allow the liquid L to be dispersed over a wide area of ​​the target, and the application can be performed reliably and easily over a wide area. Furthermore, by simply tilting the applicator 1 slightly, the projections 55 allow the liquid L to be applied locally to a relatively narrow area of ​​the target.

[0040] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to these embodiments, and other improvements and modifications may be made without departing from the spirit and teaching of the claims of the utility model. It will be readily apparent to those skilled in the art that all such improvements and modifications are included within the technical scope of the present invention. [Explanation of symbols]
