Description

Technical Field

[0001] This invention relates to an application container and an applicator for containing contents such as a medicinal hair growth agent and a cosmetic, measuring the amount used at one time, and directly applying it to an object to be coated.

Background Art

[0002] Conventionally, for example, there is an application container disclosed in Patent Document 1 in a metering and discharging container that contains contents such as a medicinal hair growth agent and a cosmetic, measures the amount used at one time, and makes it constant. This application container includes a container body having an outlet formed at one end, a middle plug member provided at the outlet and having a communication hole formed therein, a measuring cylinder member attached to the middle plug member and forming a measuring chamber between the middle plug member and having a discharge hole formed therein, and an application plug having a tip protruding from the discharge hole to the outside of the measuring chamber. The application plug is disposed so as to be movable in the axial direction of the container between a measuring position and an application position. The tip of the application plug is formed in a cylindrical shape, and a plurality of slits penetrate through the inside and outside of the cylindrical shape in the radial direction. The method of using this application container is to move the application plug to the measuring position and invert the container body. As a result, the contents in the container body flow into the measuring chamber through the communication hole, and a predetermined amount of the contents is measured. Next, when the tip of the application plug is pressed against the object to be coated, the application plug moves toward the application position. Then, the contents are discharged from between the application plug and the discharge hole of the measuring cylinder member and can be applied to the object to be coated.

[0003] In the case of the application container of Patent Document 1, since the application plug directly contacts the object to be coated, there is a risk that various bacteria and the like may enter the container. In addition, since the thin cylindrical tip of the application plug is pressed against the object to be coated to apply the contents, when the object to be coated is the skin, there is a lot of irritation to the skin and a tactile load may be felt, and the usability is not good.

[0004] To address this problem, there is a measuring and dispensing container disclosed in Patent Document 2. This measuring and dispensing container includes a container body, an inner stopper, a measuring cylinder member, and a valve having a nozzle portion that protrudes outward from the dispensing cylinder portion of the measuring cylinder member. A dispensing head made of a flexible elastomer or the like is provided at the tip of the nozzle portion that protrudes above the measuring device. The dispensing head is ring-shaped with a groove of a certain width around the nozzle portion, and has a cylindrical inner surface that surrounds the outer surface of the nozzle portion with a groove of a predetermined width, a cylindrical outer surface that goes around the outside of the inner surface, and a top surface that connects the upper ends of the inner surface and the outer surface. The top surface is located slightly higher than the tip of the nozzle portion. To use this measuring and dispensing container, first, move the valve to the measuring position and invert the container body. This measures the contents inside the container body. Next, the object to be coated is lightly tapped with the top surface of the coating head, and the impact from the tap causes small amounts of the contents to be dispensed from the nozzle. This measuring and dispensing container has a coating head that flexes appropriately and deforms easily, so the impact when tapping the object to be coated is mitigated, resulting in less irritation and a good user experience. In addition, since the top surface of the coating head is higher than the tip of the nozzle, the nozzle does not come into contact with the object to be coated, preventing the entry of bacteria.

[0005] [Patent Document 1] Japanese Patent Publication No. 2019-147608 [Patent Document 2] Japanese Patent Publication No. 2019-81615 [Overview of the project] [Problems that the invention aims to solve]

[0006] In the case of the latter type of measuring and dispensing container described above, the dispensing head comes into contact with the object to be coated, and is therefore made of a flexible material. It is difficult to select a relatively rigid material such as synthetic resin, resulting in limited material options. Furthermore, because the top surface area of ​​the dispensing head is large, the contents adhere to the top surface, leading to wasted liquid. In particular, when the object to be coated is the scalp, the contents adhere to the hair, reducing the amount of contents that adheres to the scalp.

[0007] This invention has been made in view of the problems of the background art described above, and aims to provide a coating container and coating body that offer a wide range of material options, minimize physical stress on the coated object even when using relatively rigid synthetic resins, and reduce waste of contents. [Means for solving the problem]

[0008] The present invention relates to a coating container comprising a container body having an opening at the top for containing contents, a stopper attached to the opening and having a partition wall portion that closes the opening and a through hole formed in the partition wall portion, and a nozzle portion attached to the through hole in the stopper for dispensing the contents, wherein the coating body is attached to the nozzle portion and a portion of which protrudes above the nozzle portion, and comprises a cylindrical rising portion provided on the outer circumference of the nozzle portion with the nozzle portion as the center and surrounding the outer surface of the nozzle portion, and a curved portion continuous with the upper end of the rising portion, wherein the curved portion is ring-shaped and encircles the upper end of the rising portion, the shape of the cross section of the curved portion parallel to the central axis direction and radial direction of the rising portion is an arc shape that is convex upward from the upper end of the rising portion, and the curved portion is provided with a notch that connects the inner curved surface facing downward and the outer curved surface facing upward. The notch is a slit that is long in one direction, with one end of the notch in the longitudinal direction located on the rising portion and the other end communicating with the outer peripheral edge of the curved portion opposite to the rising portion, and the notch divides the portion from the upper end of the rising portion to the peripheral edge of the curved portion.

[0009] The cross-sectional shape of the curved portion parallel to the central axis direction and radial direction of the rising portion is a shape that folds downward from the uppermost point of the curve, and the lower end of the rising portion is provided with a mounting portion that protrudes from the inner circumferential surface of the rising portion toward the center and is assembled to the outer circumferential surface of the nozzle portion, and the notch portion is, The apex of the curved portionFrom the mounting portion of the rising part Until They are arranged in a continuous sequence.

[0010] Multiple notches are provided at predetermined intervals along the circumference of the curved portion.

[0011] The aforementioned curved section The aforementioned The peripheral edge is divided by the notch portion of the curved portion The aforementioned An annular connecting band is provided to connect the peripheral edges, and the connecting band and the curved portion The aforementioned The peripheral edges are continuous with each other, forming a ring.

[0012] The present invention also relates to a coating container comprising: a container body having an opening at the top for containing contents; a stopper attached to the opening and having a partition wall portion that closes the opening and a through hole formed in the partition wall portion; a nozzle portion attached to the through hole in the stopper for dispensing the contents; and a coating body attached to the nozzle portion, with a portion of which protrudes above the nozzle portion, wherein the coating body is provided on the outer circumference of the nozzle portion with the nozzle portion as the center and consists of a cylindrical rising portion that surrounds the outer surface of the nozzle portion and a curved portion that is continuous with the upper end of the rising portion, the curved portion is ring-shaped and encircles the upper end of the rising portion, the shape of the cross section of the curved portion parallel to the central axis direction and radial direction of the rising portion is an arc shape that is convex upward from the upper end of the rising portion, and the curved portion is provided with a notch that connects the inner curved surface facing downward and the outer curved surface facing upward. The notch is a slit that is long in one direction, with one end of the notch in the longitudinal direction located on the rising portion and the other end communicating with the outer peripheral edge of the curved portion opposite to the rising portion, and the notch divides the portion from the upper end of the rising portion to the peripheral edge of the curved portion. [Effects of the Invention]

[0013] The coating container and the applicator of the present invention offer a wide range of choices for the material of the applicator. Even when using a relatively rigid synthetic resin, the physical burden on the object to be coated is small, and the usability is good. While the applicator has a folded shape with a curved portion that provides good usability, the content does not accumulate on the inner curved surface of the curved portion. Also, the contact area with the object to be coated is small, reducing waste of the content. Further, since the applicator is positioned to protrude beyond the tip of the nozzle portion for dispensing the content, the nozzle portion does not contact the object to be coated, preventing the intrusion of contaminants.

Modes for Carrying Out the Invention

[0015] The embodiments of this invention will now be described based on the drawings. Figures 1 to 5 show the first embodiment of this invention. The coating container 10 of this embodiment has a bottomed cylindrical container body 12 as shown in Figure 5, and the container body 12 is made of glass or synthetic resin. A small diameter cylindrical mouth portion 14 is integrally formed above the upright position of the container body 12, and male threads 16 are formed on the outer circumferential surface of the mouth portion 14.

[0016] An inner plug 18 made of a relatively rigid synthetic resin such as PP is fitted and attached to the opening 14. The inner plug 18 is provided with a cylindrical mounting portion 20 that fits inside the opening 14, and a flange portion 22 that abuts against the upper end surface of the opening 14 is formed on the outer circumferential surface of the mounting portion 20, protruding laterally around the outer circumferential surface. On the inner circumferential surface of the mounting portion 20 opposite to the flange portion 22, a partition wall portion 24 that closes the opening of the mounting portion 20 is formed around the inner circumferential surface. A circular through hole 25 is formed in the center of the partition wall portion 24, and a cylindrical portion 26 having a central axis parallel to the insertion direction of the mounting portion 20 is integrally provided in the through hole 25. The upper end of the cylindrical portion 26 is continuous with the partition wall portion 24, and the lower end reaches near the lower end of the mounting portion 20, and a bottom portion 28 that closes the opening of the cylindrical portion 26 is provided at the lower end of the cylindrical portion 26. Four through-holes 30 are formed in the cylindrical portion 26 and the bottom portion 28 at 90° intervals in the circumferential direction, connecting the inside of the cylindrical portion 26 to the internal space of the container body 12. A cylindrical shaft portion 32 is integrally provided at the center of the bottom portion 28. The shaft portion 32 is parallel to the insertion direction of the cylindrical portion 26, and the upper end of the shaft portion 32 is a plane located perpendicular to the axial direction, reaching a predetermined position that protrudes slightly above the partition wall portion 24.

[0017] Furthermore, at the boundary between the partition wall portion 24 and the cylindrical portion 26, a first valve seat portion 34 is provided, which is open upwards and has a groove cut out in an L-shape in cross-section all around its inner circumferential surface. The partition wall portion 24 slopes downward in a mortar shape toward the first valve seat portion 34. A stepped portion 22a is provided on the outer circumferential surface of the flange portion 22, to which a measuring device 38, which will be described later, is locked.

[0018] An engaging projection 36 is provided around the outer circumference of the upper end of the mouth portion 14, and a measuring device 38 is attached to the engaging projection 36. The measuring device 38 is made of a relatively rigid synthetic resin such as PP and is a cylindrical body attached to the tip of the mouth portion 14 of the container body 12, extending in the insertion direction of the mouth portion 14. The lower end of the measuring device 38 is a mounting cylinder portion 40 that covers the tip of the mouth portion 14 together with the flange portion 22 of the inner stopper 18, and an engaging recess 42 is provided around the inner circumference of the mounting cylinder portion 40 into which the engaging projection 36 of the mouth portion 14 is inserted. Slightly above the engaging recess 42 on the inner circumference of the mounting cylinder portion 40, a stepped portion 40a is provided around the circumference into which the stepped portion 22a of the flange portion 22 of the inner stopper 18 is fitted and locked. A measuring cylinder portion 44, which has a smaller diameter than the mounting cylinder portion 40, is continuously provided at the upper end of the mounting cylinder portion 40.

[0019] The measuring cylinder portion 44 has an inner diameter that fits snugly against the outside of the inner plug 18 in the portion above the flange portion 22 of the mounting portion 20 of the inner plug 18, and the internal space of the measuring cylinder portion 44 becomes a measuring space 46 that communicates with the cylindrical portion 26 of the inner plug 18. A dispensing cylinder portion 48, which has a smaller diameter than the measuring cylinder portion 44, is continuously provided at the upper end of the measuring cylinder portion 44. The upper end of the measuring cylinder portion 44 rises as it approaches the dispensing cylinder portion 48 and is inclined in a frustoconical shape. A closing projection 54 is formed around the inner circumferential surface of the dispensing cylinder portion 48 near the measuring cylinder portion 44, projecting from the inner circumferential surface toward the center, and the space at the center of the closing projection 54 becomes an insertion opening 56 through which a valve 60, described later, is inserted. The lower surface of the closing projection 54 becomes a second valve seat portion 58.

[0020] A valve 60 made of synthetic resin is provided inside the inner stopper 18 and the measuring device 38. The valve 60 has a cylindrical portion 62 that opens downwards, into which the shaft portion 32 of the inner stopper 18 is slidably fitted. At the lower open end of the cylindrical portion 62, a first valve 64 is provided that protrudes laterally around the outer surface of the cylindrical portion 62 and makes tight contact with the first valve seat portion 34 of the inner stopper 18. Near the end of the upper end of the cylindrical portion 62, a second valve 66 is provided that protrudes laterally around the outer surface, closes the insertion opening 56 of the measuring device 38 and makes tight contact with the second valve seat portion 58. The distance between the first valve 64 and the second valve 66 is set to be shorter than the distance between the first valve seat portion 34 of the stopper 18 and the second valve seat portion 58 of the measuring device 38 in the assembled state. The valve 60 is slidable between a dispensing state in which the first valve 64 closes the first valve seat portion 34 of the stopper 18 and a measuring state in which the second valve 66 closes the second valve seat portion 58 of the measuring device 38. The dispensing state and the measuring state are alternately switched by sliding the valve 60.

[0021] On the portion of the valve 60 opposite the cylindrical portion 62 from the second valve 66, a cylindrical nozzle portion 68 is formed, having a diameter approximately equal to the inner diameter of the insertion opening 56 of the measuring device 38, and protruding from the opposite side of the cylindrical portion 62 parallel to the insertion direction of the cylindrical portion 62. Four through holes 74 are formed in the nozzle portion 68 near the second valve 66 at 90° intervals in the circumferential direction, connecting the inner and outer surfaces of the nozzle portion 68. In the metering state, when the second valve 66 closes the second valve seat portion 58 of the measuring device 38, the through holes 74 are located above the closing projection 54 of the measuring device 38, and the metering space 46 and the inside of the nozzle portion 68 are separated. In the dispensing state, when the first valve 64 closes the first valve seat portion 34 of the stopper 18, the through holes 74 are located below the closing projection 54 of the measuring device 38, and the metering space 46 and the inside of the nozzle portion 68 are connected. Furthermore, a locking groove 70 is provided around the outer circumference of the nozzle portion 68, slightly above the through hole 74, to which the coating body 76, described later, is locked. A locking groove 72 is provided around the outer circumference of the nozzle portion 68, slightly above the locking groove 70, to which the cap 96, described later, is locked. The locking groove 72 is slightly deeper than the locking groove 70, and its upper inner surface intersects the insertion direction of the nozzle portion 68 at approximately a right angle.

[0022] The tip 68a of the nozzle portion 68 of the valve 60 is mounted so as to protrude above the closing projection 54 of the measuring instrument 38, and a coating body 76 is provided on the protruding portion. The coating body 76 can suitably be made of various elastomers, flexible materials such as LDPE, LLDPE, EVA, soft PVC, and soft urethane, as well as relatively rigid materials such as HDPE, PP, PMP, and SBC. Furthermore, even highly rigid materials such as PA, POM, PC, ABS, and saturated polyester resins such as PET, PBT, PEN, and PCTA can be suitably used by appropriately adjusting the length, width, and number of notches 88, which will be described later. Therefore, the coating body 76 has a wide range of material options.

[0023] The coating body 76 is provided in a ring shape that encircles the nozzle portion 68 of the valve 60 with a groove 77 of a certain width, and the shape of the cross-section of the coating body 76 parallel to the central axis and radial direction is constant at 360°. The coating body 76 has a cylindrical rising portion 78 that surrounds the outer circumferential surface of the nozzle portion 68 with a groove 77 of a predetermined width, and the central axis of the rising portion 78 coincides with that of the nozzle portion 68. At the lower end of the rising portion 78, a mounting portion 80 is formed all the way around, which is a mounting projection that protrudes from the inner circumferential surface of the rising portion 78 toward the center, and the space in the center of the mounting portion 80 becomes an insertion hole 82 through which the nozzle portion 68 is inserted.

[0024] On the inner circumferential surface of the insertion hole 82 of the mounting portion 80, a locking projection 84 is formed all the way around, which is inserted into the locking groove 70 of the nozzle portion 68 for assembly.

[0025] The coating body 76 has a curved portion 86 continuously provided at the upper end 78a of the rising portion 78, opposite to the mounting portion 80. The curved portion 86 is arranged in a ring shape that extends around the outside of the cylindrical rising portion 78, with the inner through-hole having a diameter matching that of the rising portion 78, and the outer peripheral portion 86a having a larger diameter than the rising portion 78. The shape of the cross-section of the curved portion 86 parallel to the central axis and radial direction is a semicircular arc that is convex upward from the upper end 78a of the rising portion 78. The peripheral portion 86a of the curved portion 86 is located below the apex that is convex upward from the curved portion 86, meaning it is folded downward, and is located at the same position as or slightly below the upper end 78a of the rising portion 78.

[0026] The curved portion 86 is provided with a notch 88 that connects the inner curved surface 86b facing downwards and the outer curved surface 86c facing upwards. The notch 88 is a long slit along the radial direction of the curved portion 86, with one end of the notch 88 in the longitudinal direction communicating with the peripheral edge 86a of the curved portion 86, and the other end located approximately midway between the upper end 78a of the rising portion 78 and the mounting projection 80. The peripheral edge 86a of the curved portion 86 is divided into multiple sections by the notch 88. Multiple notches 88 are provided at equal intervals along the circumference of the curved portion 86; in this case, eight are provided.

[0027] The peripheral edge 86a of the curved portion 86 is provided with a connecting band 90 that connects the peripheral edges 86a divided by the notch 88. The connecting band 90 is annular and formed by a curve along the circumference of the peripheral edge 86a, so that the connecting band 90 and the peripheral edges 86a of the curved portion 86 are continuous and circular. Below the notch 88 on the outer circumferential surface of the rising portion 78, a liquid-tight projection 92 is provided all the way around, protruding outwards. In the dispensing state, when the first valve 64 closes the first valve seat 34 of the stopper 18, the liquid-tight projection 92 makes liquid-tight contact with the inner circumferential surface near the tip of the dispensing cylinder portion 48 of the measuring device 38.

[0028] The peripheral edge 86a of the curved portion 86 is positioned at approximately the same height as the tip 68a of the nozzle portion 68 when assembled to the valve 60. The convex apex on the upper surface of the curved portion 86 is higher than the tip 68a of the nozzle portion 68, and this apex is provided with a hemispherical projection 94 that protrudes upward. One projection 94 is formed between each of the pair of notches 88. When the curved portion 86 is assembled to the nozzle portion 68, it does not come into contact with the dispensing cylinder portion 48 of the measuring device 38, and does not interfere with the first valve 64 of the valve 60 closing the first valve seat portion 34 of the stopper 18.

[0029] Furthermore, a detachable cap 96 is provided at the mouth 14 of the container body 12. The cap 96 has a disc-shaped upper surface 98 and a cylindrical side surface 100 that is continuous with the periphery of the upper surface 98. A female thread 102 is formed on the inner circumferential surface of the side surface 100, which is screwed onto the male thread 16 of the mouth 14 of the container body 12. The upper surface 98 protrudes downward in a frustoconical shape with a slightly inclined slope so as to be inserted into the curved portion 86 of the applicator 76, and a cylindrical liquid-stopping cylinder portion 104 is provided on the circumference of the frustoconical shape, which is liquid-tightly inserted into the groove 77 between the applicator 76 and the nozzle portion 68. A valve-lifting hook 106, which is a projection that fits into the locking groove 72 of the valve 60, is provided around the inner circumferential surface of the liquid-stopping cylinder portion 104. Inside the liquid-stopping cylinder portion 104, there is a short cylindrical insertion cylinder portion 108 that is inserted into close contact with the inner circumferential surface of the nozzle portion 68.

[0030] A retaining cylinder portion 110 is provided between the side surface 100 and the liquid-stopping cylinder portion 104 on the upper surface 98. The retaining cylinder portion 110 is cylindrical with a diameter slightly smaller than that of the side surface 100 and is provided at a predetermined distance from the inner circumferential surface of the side surface 100. The lower end of the retaining cylinder portion 110 abuts against the stepped portion 45 formed between the mounting cylinder portion 40 and the metering cylinder portion 44 of the measuring device 38 when the cap 96 is closed on the container body 12, thereby holding the measuring device 38 in place and also holding the inner stopper 18 between the measuring device 38 and the container body 12.

[0031] Next, the assembly method of the coating container 10 in this embodiment will be described. First, the nozzle portion 68 of the valve 60 is inserted from the mounting cylinder portion 40 side of the measuring device 38, and the nozzle portion 68 is made to protrude upward from the insertion opening 56 of the closing projection 54. At this time, a portion of the valve 60 that is slightly thicker than the insertion opening 56 may be provided to give a clicking sensation when inserting it, and once inserted it may be locked in place so that it does not come out. The coating body 76 is attached to the nozzle portion 68 of the valve 60 that protrudes upward from the insertion opening 56 of the measuring device 38. The coating body 76 is attached by inserting the nozzle portion 68 into the inside of the rising portion 78 from the opposite side of the curved portion 86, fitting the locking projection 84 of the mounting portion 80 of the coating body 76 into the locking groove portion 70 of the nozzle portion 68, and attaching the curved portion 86 so that it spreads outward from the extension of the dispensing cylinder portion 48. Next, the inner stopper 18 is attached to the mounting cylinder portion 40 of the measuring device 38. The mounting portion 20 of the inner plug 18 is inserted into the mounting cylinder portion 40 of the measuring device 38 from the end opposite to the bottom portion 28, and fitted into the inner circumferential surface of the quantitative cylinder portion 44. The flange portion 22 of the inner plug 18 abuts against the lower end of the quantitative cylinder portion 44, preventing it from being inserted any further. At this time, the stepped portion 22a of the flange portion 22 is locked into the stepped portion 40a of the mounting cylinder portion 40, preventing it from falling out. At this time, the shaft portion 32 of the inner plug 18 is slidably inserted inside the cylindrical portion 62 of the valve 60.

[0032] Next, the inner stopper 18, measuring device 38, valve 60, and applicator 76 are attached to the mouth 14 of the container body 12 containing the liquid 112, in the assembled state described above. First, the mounting portion 20 of the inner stopper 18 is inserted into the mouth 14 from the end on the bottom 28 side. The mounting portion 20 is fitted liquid-tightly to the inner circumferential surface of the mouth 14, and the flange portion 22 abuts against the upper end surface of the mouth 14 to prevent it from being inserted any further. At this time, the engaging projection 36 of the mouth 14 is fitted into the engaging recess 42 of the measuring device 38 and locked in place, preventing it from falling out.

[0033] Furthermore, a cap 96 is attached to the mouth 14 of the container body 12. The cap 96 is placed over the curved portion 86 of the applicator 76 from above and rotated around its axis to screw the female thread 102 onto the male thread 16 of the mouth 14. The stepped portion 45 of the measuring device 38 is pressed against the retaining cylinder portion 110 of the cap 96, and the stopper 18 is closed with the stopper 18 sandwiched between it and the mouth 14 of the container body 12, resulting in a sealed state as shown in Figure 1. At this time, the valve 60 and the applicator 76 are pushed down by the liquid stopper cylinder portion 104, and the first valve 64 of the valve 60 closes the first valve seat portion 34 of the stopper 18, resulting in a dispensing state, and the inside of the container body 12 is isolated from the measuring space 46. In this state, even if the container body 12 is tilted, the liquid 112 contained in the container body 12 will not come out, and the applicator container 10 can be safely transported and stored.

[0034] The liquid preparation 112 contained in this application container 10 can be a variety of products. For example, a hair growth agent, the active ingredient of which may be minoxidil. A hair tonic may also be used, and the active ingredients of a hair tonic may include, for example, carpronium chloride, Swertia japonica extract, tocopherol acetate, trans-3,4-hydroxyflavanone, nicotinamide, benzyl nicotinate, pantothenyl alcohol, pantothenyl ethyl ether, β-glycyrrhetinic acid, dipotassium glycyrrhizate, glyceride pentadecanoate, acetyl decapeptide-3, acetyl tetrapeptide-3 / red clover flower extract, ginkgo biloba leaf extract, carrot extract, ethinylestradiol, orchid extract, L-arginine, and watercress. These include extracts, cytokines, calamus root extract, stemoxydin, cepharanthine, chuanxiong extract, ginseng extract, swallow's nest extract, chili pepper extract, cordyceps extract, niacinamide, garlic extract, saw palmetto, iris extract, Isodon leaf / stem extract, human oligopeptide-21, pyrrolidinyl diaminopyrimidine oxide, 6-benzylaminopurine, capixyl, Enmeiso extract, estradiol benzoate, isopropylmethylphenol, adenosine, Sophora flavescens extract, ginger tincture, etc. Furthermore, liquid formulation 112 may also be an antifungal agent, and the antifungal components may include, for example, efinaconazole, liranaftate, luliconazole, butenafine, terbinafine, amorolfine, lanoconazole, neticonazole, bifonazole, ketoconazole, etc. In addition, liquid formulation 112 may be an anti-inflammatory analgesic, and the active ingredients of such anti-inflammatory analgesics include, for example, indomethacin, diclofenac, felbinac, loxoprofen, ketoprofen, methyl salicylate, glycol salicylate, etc. Liquid formulation 112 may also be an antipruritic, and the active ingredients of such antipruritics include, for example, crotamiton, diphenhydramine hydrochloride, lidocaine, etc. It may also be a medication for eczema and dermatitis, and the active ingredients of such a medication include, for example, prednisolone valerate acetate, l-menthol, dexamethasone acetate, dl-camphor, fluocinolone acetonide, glycyrrhizic acid, isopropylmethylphenol, betamethasone valerate, etc.

[0035] Next, the method of using the application container 10 will be described. When taking the liquid 112 out of the container body 12 for use, first rotate the cap 96 around its axis to release the threads between the female thread 102 and the male thread 16 of the opening 14, and then pull up the cap 96 approximately parallel to the insertion direction of the valve 60 to remove it. At this time, the valve pull-up hook 106 of the cap 96 is inserted into the locking groove 72 of the valve 60 and is locked with a certain degree of force, so as the cap 96 is pulled up, the valve 60 and the application body 76 slide and are pulled up. Since the cylindrical part 62 of the valve 60 is slidably fitted onto the shaft part 32 of the inner stopper 18, it slides along the axial direction of the shaft part 32. When the second valve 66 of the valve 60 comes into contact with the second valve seat part 58 of the closing projection 54 of the measuring device 38, the valve 60 stops being pulled up any further. When the cap 96 is further pulled up, the engagement between the valve lifting hook 106 and the locking groove 72 of the valve 60 is released, and the cap 96 is removed. At this time, as shown in Figure 2, the second valve 66 of the valve 60 closes the second valve seat 58 of the measuring device 38, and the first valve 64 opens the first valve seat 34 of the stopper 18, creating a measuring state where the internal space of the container body 12 communicates with the measuring space 46 of the measuring device 38.

[0036] Then, when the container body 12 is inverted in this measuring state, as shown in Figure 3, the liquid 112 inside the container body 12 passes through the through hole 30 of the inner stopper 18 and flows into and fills the measuring space 46 of the measuring device 38, and a fixed amount is measured. Since the second valve 66 of the valve 60 blocks the second valve seat 58 of the measuring device 38, the liquid 112 inside the measuring space 46 does not leak out from the nozzle part 68. In this state, the partition wall 24 of the inner stopper 18 becomes an inclined surface that is located upward as it approaches the through hole 25, so that the liquid 112 is reliably filled into the measuring space 46. This solves the problem that if the partition wall 24 is a horizontal surface, an air pocket will form between the partition wall 24 and the mounting part 20 unless the container body 12 is inverted precisely vertically, and the liquid 112 will not be filled into the measuring space 46, making accurate measurement impossible.

[0037] Next, while maintaining that state, the applicator 76 is brought close to the object to be coated, such as the scalp, and the curved portion 86 of the applicator 76 is pressed against the object to be coated. As shown in Figure 4, the valve 60 is pushed down into the measuring device 38, the first valve 64 closes the first valve seat 34, the second valve 66 separates from the second valve seat 58, the through hole 74 of the valve 60 is exposed to the measuring space 46 of the measuring device 38, and the measuring space 46 communicates with the nozzle portion 68. Then, the liquid 112 that was filling the measuring space 46 flows through the through hole 74 into the nozzle portion 68 and exits from the tip portion 68a. At this time, since the first valve 64 is blocking the first valve seat 34, the liquid 112 in the container body 12 does not flow out, and only the liquid 112 that was filling the measuring space 46 is dispensed, so no excess liquid 112 is dispensed from the container body 12, and the amount is constant. However, because the nozzle portion 68 has a small diameter, the liquid 112 will not be dispensed continuously simply by inverting the container body 12.

[0038] Here, the curved portion 86 of the applicator 76 is used to lightly tap the object to be coated, and the impact of the tapping causes small amounts of liquid 112 to be dispensed from the nozzle portion 68. The curved portion 86 is an arc shape that is convex from the upper end 78a of the rising portion 78, and multiple notches 88 are provided at equal intervals along the circumference of the curved portion 86, so it bends and deforms easily, reducing the impact on the object to be coated and minimizing irritation. The peripheral edge 86a of the curved portion 86 is provided with a connecting band 90 that connects the peripheral edges 86a divided by the notches 88, so the connecting band 90 and the peripheral edges 86a of the curved portion 86 are continuous and circular, so that hair and other debris from the object to be coated do not get entangled in the curved portion 86. The apex of the outer curved surface 86c of the curved portion 86 protrudes more than the tip 68a of the nozzle portion 68, so the thin and hard tip 68a of the nozzle portion 68 does not come into contact with the object to be coated.

[0039] A groove 77 is provided between the rising portion 78 of the applicator 76 and the outer surface of the nozzle portion 68, so they do not come into contact with each other. As a result, most of the liquid 112 dispensed from the nozzle portion 68 does not transfer to the applicator 76, and is instead precisely dropped onto the object to be coated from the small-diameter nozzle portion 68. The liquid 112, which has been evenly dropped in small amounts onto the object to be coated, is then lightly tapped and vibrated by the curved portion 86 to allow it to penetrate the object. Because the curved portion 86 has a notch 88, the contact area with the object to be coated is small, which reduces the adhesion of the liquid 112 from the object to be coated, so the liquid 112 is not wasted and can be applied efficiently.

[0040] After use, the container body 12 is turned upright again and the cap 96 is attached, creating a liquid-tight seal with the liquid-stopping cylinder portion 104, insertion cylinder portion 108, and retaining cylinder portion 110 of the cap 96, ensuring safe storage. Furthermore, even if the liquid 112 penetrates the curved inner surface 86b of the curved portion 86 during measuring or application, the notch portion 88 is provided in communication with the curved inner surface 86b and the curved outer surface 86c, so the liquid 112 is discharged without accumulating, and when the container body 12 is turned upright, the liquid 112 that has accumulated on the curved inner surface 86b does not drip down.

[0041] According to the coating container 10 and coating body 76 of this embodiment, there are many material options for the coating body 76, and even if a relatively rigid synthetic resin is used, the physical burden on the object to be coated is small, resulting in a good user experience. Even if the coating body 76 is made of a relatively rigid synthetic resin, the curved portion 86 that contacts the object to be coated is arc-shaped, resulting in less irritation, and the curved portion 86 is divided into thin sections by notches 88 provided in the radial direction, resulting in high flexibility. By providing multiple notches 88 in the radial direction of the curved portion 86, the cushioning effect of the curved portion 86 is evenly improved in the circumferential direction. As a result, the curved portion 86 bends appropriately and deforms easily, and when pressed against and tapped on the object to be coated, the impact can be mitigated, resulting in less irritation, no pain, a good tactile feel, and a comfortable massage while gently applying to the object to be coated, resulting in a good user experience. By appropriately adjusting the length, width, and number of notches 88, the flexibility of the curved portion 86 can be adjusted, and it can be suitably used according to the type of liquid 112, the method of use, and the object to be coated.

[0042] The peripheral edge 86a of the curved portion 86 is provided with a connecting band 90 that wraps around and connects the peripheral edges 86a divided by the notch 88. This prevents hair and other debris from getting tangled in the curved portion 86, which is divided into thin sections by the notch 88, and prevents tangled hair from falling out. The curved portion 86 is semicircular in shape, and the peripheral edge 86a is folded back, so the peripheral edge 86a does not come into contact with the object to be coated. Moreover, the liquid 112 does not accumulate in the inner curved surface 86b which folds back to form a pocket, and the liquid 112 passes through the notch 88 and is discharged to the outer curved surface 86c, resulting in minimal waste of the liquid 112. Furthermore, the liquid 112 accumulated in the inner curved surface 86b which folds back to form a pocket does not drip when the container body 12 is upright. Since the curved portion 86 is provided with a notch 88, the contact area of ​​the liquid agent 112 adhering to the curved portion 86 is reduced, as is the contact area between the object to be coated and the curved portion 86. As a result, the dispensed liquid agent 112 is not wasted, and the liquid agent 112 can be efficiently applied directly to the object to be coated. In particular, when the object to be coated is the scalp, reducing the contact area between the scalp and the curved portion 86 reduces the adhesion of the liquid agent 112 to the hair, allowing for efficient application of the liquid agent 112 to the scalp.

[0043] The coating container 10 has a simple structure, allowing the applicator 76 to be attached to the tip 68a of the nozzle 68, the applicator 76 to be placed against the object to be coated, and the valve 60 to be pressed to dispense the liquid 112. Moreover, a fixed amount of liquid 112 can be reliably measured and used accurately. The apex of the curved outer surface 86c of the curved portion 86, which is the top surface of the applicator 76, protrudes more than the tip 68a of the nozzle 68, so the hard nozzle 68 does not come into contact with the object to be coated. Furthermore, contamination of the object to be coated by bacteria from the nozzle 68 can be prevented. A groove 77 is provided between the upright portion 78 of the applicator 76 and the outer surface of the nozzle 68, so the liquid 112 dispensed from the nozzle 68 does not run down to the applicator 76, but drops vertically onto the object to be coated, allowing for precise targeting of the application location.

[0044] Next, a second embodiment of the present invention will be described with reference to Figures 6 and 7. Here, components similar to those in the above embodiment are denoted by the same reference numerals and their descriptions are omitted. In this embodiment, the coating container 114 does not have the connecting band 90 provided in the above embodiment on the peripheral edge 86a of the curved portion 86 of the coating body 76. The peripheral edge 86a of the curved portion 86 is divided by a notch 88.

[0045] The coating container 114 of this embodiment has the same effects as the above embodiment when used in the same manner. Furthermore, the structure is simpler, and the curved portion 86 divided by the notch 88 can bend and deform separately, resulting in less irritation to the object being coated.

[0046] Next, a third embodiment of this invention will be described with reference to Figures 8 and 9. Here, components similar to those in the above embodiments are denoted by the same reference numerals and their descriptions are omitted. The coating body 76 of the coating container 116 in this embodiment has a cylindrical rising portion 78, and a curved portion 118 is continuously provided at the upper end 78a of the rising portion 78. The curved portion 118 is ring-shaped, tapering around the inside of the cylindrical rising portion 78, and the inner through-hole has a smaller diameter than the rising portion 78. The shape of the cross-section of the curved portion 118 parallel to the central axis and radial direction is a semicircular arc shape that is convex upward from the upper end 78a of the rising portion 78. The inner edge 118a of the curved portion 118 opposite to the rising portion 78 is located below the apex that is convex upward from the curved portion 118, that is, it is folded downward and is located at the same position as or slightly below the upper end 78a of the rising portion 78.

[0047] The curved portion 118 is provided with a notch 120 that connects the inner curved surface 118b facing downwards and the outer curved surface 118c facing upwards. The notch 120 is a long slit in the direction along the radial direction of the curved portion 118, with one end of the notch 120 in the longitudinal direction communicating with the inner edge 118a of the curved portion 118, and the other end located approximately midway between the upper end 78a of the rising portion 78 and the mounting portion 80. The inner edge 118a of the curved portion 118 is divided by the notch 120. Multiple notches 120 are provided at equal intervals along the circumference of the curved portion 118; in this case, eight are provided. The inner edge 118a of the curved portion 118 is provided with a ring-shaped connecting band 122, which consists of the inner edge 118a divided by the notch 120. The connecting band 122 is sized to fit inside the tip portion 68a of the nozzle portion 68, and the inner edge portion 118a of the curved portion 118 is continuous with the upper surface of the connecting band 122, which is one of the surface directions.

[0048] A large-diameter receiving recess 124 for accommodating the connecting band 122 is provided on the inner circumferential surface of the tip portion 68a of the nozzle portion 68 of the valve 60, communicating upward. The vertical length of the receiving recess 124 is longer than the vertical length of the connecting band 122, and the connecting band 122 is slidable up and down while accommodating the receiving recess 124.

[0049] When the coating body 76 is assembled to the valve 60, the connecting band 122 is almost flush with the tip 68a of the nozzle portion 68. The apex of the upper surface of the curved portion 118, which is convex upwards, protrudes above the tip 68a of the nozzle portion 68.

[0050] The coating container 116 of this embodiment has the same effects as the above embodiment when used in the same manner. Furthermore, the coating body 76 is compact, and the connecting band 122 is guided by the nozzle portion 68 and slidable, so when the curved portion 118 is pressed against the object to be coated and a downward force is applied, it can move smoothly downward, resulting in less irritation to the object to be coated.

[0051] Next, a fourth embodiment of the present invention will be described with reference to Figures 10 and 11. Here, components similar to those in the above embodiments are denoted by the same reference numerals and their descriptions are omitted. The coating body 76 of the coating container 126 in this embodiment has a cylindrical rising portion 78, and a curved portion 128 is continuously provided at the upper end 78a of the rising portion 78. The curved portion 128 is ring-shaped, extending around the outside of the cylindrical rising portion 78, with an inner through-hole having a diameter matching that of the rising portion 78, and an outer peripheral edge 128a having a larger diameter than the rising portion 78. The shape of the cross-section of the curved portion 128, parallel to the central axis and radial direction, is a quarter-circular arc shape that is convex upward from the upper end 78a of the rising portion 78, and there is no downward fold from the apex of the curve. The peripheral edge 128a of the curved portion 128 is located diagonally above and outside the upper end 78a of the rising portion 78, and this is the apex of the upward convexity.

[0052] The curved portion 128 is provided with a notch 130 that connects the inner curved surface 128b facing downwards and the outer curved surface 128c facing upwards. The notch 130 is a long slit in the direction along the radial direction of the curved portion 128, with one end of the notch 130 in the longitudinal direction at the apex of the inner curved surface 128b of the curved portion 128, and the other end located approximately midway between the upper end 78a of the rising portion 78 and the mounting portion 80. The peripheral edge 128a of the curved portion 128 is divided by the notch 130. Multiple notches 130 are provided at equal intervals along the circumference of the curved portion 128; in this case, there are 10. The peripheral edge 128a of the curved portion 128 is provided with a ring-shaped connecting band 132, which consists of the peripheral edges 128a divided by the notches 130. The connecting strip 132 is provided with an upper surface 132a that faces upward in a substantially horizontal direction.

[0053] The coating container 126 of this embodiment has the same effects as the above embodiment when used in the same manner. The notch 130 is provided up to the apex of the curved inner surface 128b which is convex upward of the curved portion 128, and although it is shorter than in the above embodiments, it can reliably discharge the liquid 112 that accumulates in the groove 77. The connecting band 132 has a flat upper surface 132a, so the upper surface 132a comes into contact with the object to be coated, distributing the pressure and reducing irritation to the object to be coated. Since there is no notch 130 on the upper surface 132a, there is no feeling of unevenness. The curved portion 128 has no folds and has a simple structure.

[0054] It should be noted that the coating container and coating body of this invention are not limited to the above embodiments, and the materials, shapes, etc., can be freely changed. The longitudinal length of the notch only needs to be provided continuously from the apex of the curve of the curved section to the rising section, and can be freely changed according to the characteristics of the material of the object to be coated or the coating body 76. The width and number of the notches can also be changed, as long as they improve the flexibility of the curved section, but it is preferable to provide three to six or more. The contents can be any liquid that drips from the nozzle, and can be used for various things other than liquids. The coating container may not have a measuring device, and in this case, the nozzle and coating body can be integrally molded. [Explanation of symbols]
