Description

  The present invention relates to an applicator incorporating a coating liquid such as paint, paint, ink, correction liquid, glue, adhesive, cosmetic liquid, chemical liquid, repair agent, coating agent, and the like.

As an applicator in which an application destination member having an application portion is attached in front of an opening of a container having an application liquid storage chamber therein, and a large number of protrusions appear and disappear around the application destination member, Japanese Patent Laid-Open No. 9-201419 No. 2 is known.
The applicator disclosed in Japanese Patent Application Laid-Open No. 9-201419 is an applicator container provided with an applicator head 4 for exuding liquid in the container body at the mouth portion 2 of the squeeze container body 1. A cylindrical scraper 5 forming a wavy scraping claw 6 is screwed so as to be able to appear and retract. In addition, a valve that opens by pressing inside the application head 4 may be provided.
Japanese Patent Application Laid-Open No. 9-201419 “Applicator with scraper”.

When the built-in coating solution is a chemical solution such as an insect bite and is applied to the affected area, it is applied by pressing the application destination lightly against the inflamed area of the skin, or applied to the inflamed area of the skin. There is a case where the application destination is strongly pressed and applied so as to reduce itchiness by stimulation of the pressing force of the application destination, or the strength of pressing of the application destination to the skin may be used properly.
In addition, when the coating liquid incorporated is a synthetic glue liquid containing polyvinyl alcohol as a main component and the application tool is used for bonding paper or the like, when the application tool is applied to a narrow surface, it is applied thinly. In addition, when applying this applicator over a wide surface, it should be applied thickly so that the previously applied glue will not dry during the application work, or it may be applied thinly to the part where it is applied thickly like a musical score. There are cases where it is desired to use a thin coating and a thick coating (or blotting) separately, such as a coating method (spraying) in which the spot is parallel.
However, in the case of applying a chemical solution with an applicator provided with a protrusion that protrudes and protrudes around a conventional circular application portion, it is good to apply lightly with the protrusion being submerged. However, there was an application problem even when trying to apply an application with irritation by strongly pressing the application point to the affected part with itching after being touched by a mosquito with protrusions in order to reduce itching. In other words, since the position of the application part where the chemical liquid oozes out and the protrusion around the application part are separated, the chemical application and the stagnation-reducing stimulus must be performed at different sites, and the chemical application and the stagnation reduction at the same position It was impossible to stimulate at the same time.
Furthermore, when applying paste with an applicator provided with protrusions that protrude and appear around a conventional circular application portion, it may be thinly applied while the protrusions are submerged. However, in thick coating with the protrusions submerged, if the squeeze container is pressed strongly to try to discharge a large amount of glue liquid, the container may be pushed too much and a lot of glue liquid may come out. Further, in the thick coating with the protrusions protruding, it is difficult to make the coating thickness uniform unless the container is placed perpendicularly to the application surface and all the protrusions are in contact with the application surface. This vertical coating operation is difficult to perform compared to a general method of coating operation with a slight inclination.
Therefore, the present invention provides a strength operation for pressing the application portion against the application surface, that is, by properly using the pressing force, the application feeling is different depending on the strength of the application touch in the chemical solution, and the strength of the application touch is different in the adhesive solution. It is an object to provide an applicator that can adjust the thickness.

  The present invention provides an applicator provided with a coating tip having a circular coating portion at the tip in front of an opening of a container having a coating liquid storage chamber therein, and a large number of dispersed protrusions are arranged on the surface of the coating destination. Or a large number of dispersed protrusions arranged behind the application destination, or a large number of dispersed protrusions arranged so as to appear and disappear.

  The present invention provides an applicator provided with a coating tip having a circular coating portion at the tip in front of an opening of a container having a coating liquid storage chamber therein, and a large number of dispersed protrusions are arranged on the surface of the coating destination. Or a large number of dispersed protrusions are arranged behind the application destination, or a large number of dispersed protrusions are arranged so that they appear and disappear. The application feeling action varies depending on the strength of the application touch, and an applicator that can be applied thicker or thinner depending on the strength of the application touch can be provided with the applicator storing the paste liquid.

The spring valve 5 is fitted and joined to the front shaft 2 by a convex rib provided on the outer periphery of the rear portion 5c and a circumferential groove provided on the inner surface behind the base 2a of the front shaft 2.
Further, the rear end of the central opening of the top portion 2b of the front shaft 2 and the step portion in the middle of the front and rear of the tip portion 5a of the spring valve 5 are pressed against each other by the spring portion 5b of the spring valve 5 to form a valve mechanism. Incidentally, the tip of the tip portion 5a of the spring valve 5 is provided so as to slightly protrude from the tip of the center opening of the top portion 2b of the front shaft 2.
Reference numeral 6 is a bottomed cylindrical cap that can be easily screwed to and detached from the container 1, and is formed of a substantially transparent grade material of a polypropylene resin material of thermoplastic resin. An internal thread portion is provided behind the inner surface of the cap 5. Of course, the cap 5 protects the coating destination 3 and prevents drying of the coating liquid adhering to the coating destination 3 during storage of the applicator.
In this embodiment, the container 1 is made of a flexible material, and the discharge amount of the coating liquid can be adjusted by adjusting the pressure of the hand holding the container 1, but other discharge structures, For example, a pump mechanism may be provided at the rear of the container to form an internal pressurizing structure, or an internal pressurizing structure in which a pressurized gas is enclosed in a hard container may be used.

All members including the application destination 3 of the present embodiment are intended to be synthetic materials such as thermoplastic resins and synthetic rubbers. The material used here may be adopted according to the purpose of use such as the built-in liquid characteristics such as oiliness and aqueousness of the applicator, the appearance of the appearance, and the transparent material.
For example, in a single resin material of thermoplastic resin, acrylonitrile / styrene resin, acrylonitrile / butadiene / styrene resin, polyvinyl chloride resin, polyacetal resin, polyamide resins (PA6 / PA66 / PA610 / PA11 / PA12), polyarylate resin , Thermoplastic elastomers (urethane, olefin, styrene, polyamide, polyester, nitrile), polyether ether ketone, polysulfone resin, low density polyethylene, high density polyethylene, linear low density polyethylene, polyethylene terephthalate , Polycarbonate resin, polystyrene resin, polyphenylene ether resin, polyphenylene sulfide resin, polybutadiene resin, polybutylene terephthalate resin, polyethylene naphthalate Resins, polypropylene resins, and methacryl resins. In addition, for the purpose of improving heat resistance, cold resistance, impact resistance, etc., a polymer alloy material obtained by mixing these various resin materials can be used, or the characteristics of each additive can be modified. In addition, products once used in the market can be sorted by molding material, recycled recycled molding material, and molding material (off grade) that is out of specification at the material manufacturer can be used.
In particular, the application destination 3 may be a continuous air hole-like soft material, and urethane foam or a solid soft material may be formed by a number of fine perforations. Soft materials include the various elastomer materials described above and synthetic rubber. Synthetic rubbers include butadiene rubber, polyisoprene, chloroprene rubber, nitrile rubber, which are diene-based synthetic rubbers, butyl rubber, ethylene-propylene rubber, urethane rubber, chlorosulfonated polyethylene, acrylic rubber, fluororubber, which are non-diene-based synthetic rubbers, Other rubbers include silicon rubber, chlorinated polyethylene, epichlorohydrin, polysulfide rubber and the like.
In addition, each member such as the application destination 3 used for an applicator that dislikes the propagation of various bacteria such as a drug solution applicator can be molded using a material in which an antibacterial agent is kneaded in advance. There are organic and inorganic antibacterial agents, but inorganic ones are preferred over organic ones. As inorganic substances, silver, copper, zinc, copper oxide, etc., and these substances are oxidized. Examples include those adsorbed and fixed on inorganic fine particles such as silicon and calcium carbonate. Incidentally, commercially available antibacterial agents include Avatarizer AW (manufactured by Sangi Co., Ltd.), Zeomic (manufactured by Shinagawa Fuel Co., Ltd.) and the like.

The operation will be described.
In the above-described embodiment, when the chemical solution is lightly applied, the protrusion 3a of the application destination 3 comes into light contact with the inflamed part of the skin. At the same time, the tip portion 5a of the spring valve 5 is pushed backward through the application destination 3, the valve mechanism is opened, and the built-in chemical liquid exudes. As a result, the medicinal solution can be applied lightly and gently to the damaged affected area without causing pain during application.
Next, when the application destination 3 is strongly pressed against the affected part, the tips 5a of the protrusions 3a are pressed apart from each other, and at the same time, the front part 5a of the spring valve 5 is pushed backward via the application destination 3. As a result, the valve mechanism opens and the internal chemicals ooze out. When attention is paid to the tip of the application destination 3, a skin bulge occurs between the protrusions 3 a of the application destination 3. In this way, since many tips of the protrusions 3a are spaced and pressed against the skin, the surface of the skin is pressed against and compressed, and the stretched portion caused by the bulge generated between the pressings. At the same time, the chemical solution from the container is supplied to the skin surface. When the application destination 3 is moved on the skin in this state, the compressed portion and the stretched portion of the skin are reversed.
Here, looking at the affected area, the compressed part of the skin stimulates with a weak pain sensation to relieve itching, and in the stretched part of the skin, the absorption of chemicals is promoted by the expansion of cells and hair roots . That is, it is possible to simultaneously reduce the itchiness of the affected area and speed up the swallowing of the drug solution, thereby increasing the drug efficacy.
In this way, a light application touch can be applied lightly and gently so as not to cause pain when applied to an injured affected area, and a strong application touch can alleviate the itchiness of the affected area and accelerate drug efficacy.

FIG. 3 shows a second embodiment, and shows a cross-sectional view of the main part front.
The container 1, the coupling ring 4, the spring valve 5, and the cap 6 are the same as in the first embodiment. A front shaft 12 having a substantially bottomed cylindrical shape is fitted in front of the container 1. The base 12a of the front shaft 12 is the same as in the first embodiment. A thin top 12b whose center is open is provided at the tip of the base 12a. In front of the top portion 12b, a large number of substantially identical protrusions 12c are provided so as to be dispersed.
In front of the front shaft 12, a soft coating tip 13 having a continuous air hole shape is provided. The surface of the application destination 13 is a smooth application part 13b.
The operation will be described. When the chemical solution is lightly applied, the affected part is brought into contact with the smooth surface of the application part 13a of the application destination 13 and can be applied more gently than in the first embodiment. This is because the protrusion 12 c is provided behind the application destination 13. When the application destination 13 is strongly pressed against the affected area, each tip of the protrusion 12c of the front shaft 12 is pressed against the affected area via the application destination 13, and the same application as in the first embodiment is applied. It fulfills its function.
As another example, in the case of using an applicator containing glue solution for bonding paper, when the application destination 13 is lightly pressed against the paper surface, the application portion 13b of the application destination 13 is lightly in contact with the application destination 13 at the same time. Accordingly, the front portion 5a of the spring valve 5 is pushed backward, the valve mechanism is opened, and the built-in paste liquid is discharged. As a result, the glue liquid can be applied thinly to a narrow portion of the paper surface. Further, when the application destination 13 is strongly pressed against the paper surface, the tips of the projections 12c of the front shaft 12 are pressed against the paper surface via the application destination 13, and the contact gap between the paper surface and the application destination 13 is increased. A contact state in which a narrow gap portion and a wide gap portion are mixed with or without the protrusion 12c is obtained. The size of this gap becomes a coating thickness unevenness of the paste liquid, and even if it is applied on a wide surface, the previously applied portion is not dried. Further, even with a general application operation in which the applicator is slightly inclined, it can be applied to a uniform thickness without hindrance.

4 to 6 show a third embodiment. 4 shows a cross-sectional view of the front of the main part, FIG. 5 shows a top view excluding the cap 26 of FIG. 4, and FIG. 6 shows a state in which the protrusion 27c protrudes without the cap 26 of FIG.

The front shaft 22 includes a cylindrical base portion 22a inserted in pressure contact with the inner surface of the opening of the container 21, a spring portion 22d substantially corresponding to the spring portion 5b of the spring valve 5 of the first embodiment, A tip portion 22e substantially corresponding to the tip portion 5a of the spring valve 5 of the embodiment is provided. A longitudinal rib 22f extending in the front-rear direction is provided in front of the outer periphery of the base portion 22a.
A substantially bottomed cylindrical coating destination 23 is provided on the front outer side of the front shaft 22. The tip of the application destination 23 is open at the center, and through holes 23a in which a large number of holes are dispersed are provided around the tip. Further, a circumferential groove is provided on the rear inner surface of the cylindrical portion of the application destination 23 and is fitted to the front rib of the container 21. On the other hand, on the front inner surface of the cylindrical portion of the application destination 23, three waved wave ribs projecting toward the axis around the entire circumference are provided. The tip portion 22e of the front shaft 22 is inserted through the central opening of the application destination 23 and is provided so as to protrude.
Furthermore, a substantially bottomed cylindrical moving body 27 is provided behind the application destination 23. The longitudinally moving body 27 includes a cylindrical tube 27a and a thin plate-shaped top portion 27b. A large number of protrusions 27 c are provided in front of the top portion 27 b of the longitudinally moving body 27 so as to be inserted through the large number of through holes 23 a of the application destination 23. A circumferential groove is provided in front of the outer periphery of the cylinder 27a of the longitudinally moving body 27.
An annular back-and-forth motion ring 28 is provided in the coating destination 23. The front / rear moving ring 28 may be provided outside the cylinder 27 a of the front / rear moving body 27. Further, the front inner side of the front / rear moving ring 28 protrudes toward the axial center, and is fitted to the entire circumferential groove of the cylinder 27a of the front / rear moving body 27. Further, a large number of protrusions scattered throughout the entire circumference are provided on the outer periphery of the front / rear moving ring 28 and engaged with the wave ribs of the application destination 23. Further, on the inner surface of the front / rear moving ring 28, there is provided a vertical rib that meshes with a vertical rib provided on the front outer periphery of the base portion 22 a of the front shaft 22.
The longitudinal moving body 27 and the longitudinal moving ring 28 may be provided as an integral member.
The operation will be described. When the cap 26 is pulled out in the reverse direction of the container 21 and then rotated around the axis of the application destination 23, the longitudinally moving body 27 appears and disappears via the longitudinally moving ring 28. As a result, a large number of protrusions 27 c of the longitudinally moving body 27 appear and disappear from the surface of the application destination 23.
When the chemical solution is lightly applied in a state where the numerous protrusions 27c of the longitudinally moving body 27 are immersed in the application destination 23, it can be gently applied as in the second embodiment. Further, if the coating is performed strongly with a large number of protrusions 27c of the longitudinally moving body 27 protruding from the coating destination 23, the same application action as in the first embodiment is achieved.
Also, when the applicator containing the paste liquid is lightly applied to the adhesion between papers in a state where the numerous protrusions 27c of the longitudinally moving body 27 are submerged in the application destination 23, the adhesive is the same as in the second embodiment. The liquid can be applied thinly. Moreover, if it applies strongly in the state where many protrusions 27c of the longitudinally moving body 27 protrude from the application tip 23, it can be applied to an equal thickness as in the second embodiment.
In this way, the protrusion and disengagement state of the protrusion 27c can be adjusted in advance in accordance with the strength application operation.
