    [0001] The present invention relates to an applicator for cosmetics and for medical use, which comprises a container for applying a liquid and which is intended to uniformly apply a liquid of a relatively high viscosity and the like. [0002] Conventionally, there have been various proposals for applicators for applying liquid solutions of a content. For example, there have been applicators that simply apply and spread a liquid with a cotton swab or sponge, and applicators that dispense a liquid and spread the liquid by means of its application portion of the container, disclosed in Japanese Patent Application Laid Open Publication No. 2010-42046 (Patent Document 1) and Japanese Patent Application Laid Open Publication No. 2007-130157 (Patent Document 2). Usually, for the application of the liquid, it is expected that the applicator spreads the liquid in a thin layer and uniformly on the application surface. [0005] The use of the fingers for application facilitates the uniform distribution of the liquid, but this poses the problem of dirtying the fingers. The use of cotton pads makes the application work easy, but poses the problem of non-uniform application and adhesion of fibers. When a sponge is used as an application part, the liquid impregnates the surface of the sponge and has a tendency to damage the application surface, causing hygienic problems. In addition, there is also another problem, namely that the component which easily penetrates the sponge, as a solvent of the liquid, is absorbed by the sponge, changing the composition of the liquid retained in the application portion . [0008] There have also been various types of applicators using brushes as application bodies. A brush is an application body (part of application) formed by a bundle of fibers, and so leaves traces of fibers on the surface applied during application, and it becomes difficult to apply the liquid finely and in a uniform way. In the silicone applicator as proposed in Patent Document 1 of a liquid applicator, although the application body will not absorb the liquid, the application body has an approximately uniform elasticity because that the application body is formed by a silicone molding. Therefore, when the applicator body of a substantially spherical surface is pressed against the application surface, the pressure becomes higher in the center of the contact zone on the sphere than in the center surround, and this In fact, the liquid is not applied uniformly but is distributed in a thinner layer in the center of the contact zone and its vicinity than in the surrounding thereof. Therefore, when the liquid is applied by moving the application body under this condition, the liquid, after application, will not be uniform, but a thin layer application of the liquid will appear along the center trace. and its neighborhood. In addition, when the applicator is a flat application body, it is possible to apply a uniform pressure if the liquid is applied to the surface of a perfectly flat object 15. However, even in this case, if the application body is slightly inclined, or if the application surface is not a perfect plane, the pressure becomes uneven so that the thickness obtained of the application liquid becomes not equal. When a liquid dispensing hole is provided in the applicator body, as in Patent Document 1, the applied liquid is scraped by the edge forming and surrounding the hole, when the applicator moves or moves. As a result, the scraped trace tends to appear on the liquid surface along the trace of the dispensing or dispensing hole. In particular, a perceptible amount of liquid is scraped off by the edge configured as shown in FIG. 6 of Patent Document 1. [0012] When the applicator comprises an elastic application body similar to a spatula able to deform completely. in accordance with the application surface to be covered, as disclosed in Patent Document 2, the variation of the application body pressure in the width direction can be suppressed by the deformation of the application body which follows the application portion. However, the pressure force of the elapsed time-dependent applicator can not be made uniform, and thus the application thickness becomes non-uniform with respect to the direction of liquid application. In addition, this configuration also poses the problem that when a dispensing hole is formed in the application body, the liquid is scraped by the edge forming and surrounding the hole so that it is not possible. to obtain a uniform or regular application surface. Related Art Documents [Patent Document 1] Japanese Published Patent Application 2010-42046 [Patent Document 2] Japanese Published Patent Application 2007-1 301 57 [0015] In view of the circumstances set forth herein above, the object of the present invention is to provide an applicator with an applicator body which is non-absorbent and which is able to spread and uniformly apply an application liquid to the application surface to be covered, without scraping the liquid applied during the application. We will now describe the circumstances that led to the design of the present invention. When a liquid is applied with the finger, the liquid can be applied easily and uniformly on the application surface to be covered even if this surface is curved. This is possible for the following reasons: [0018] (a) There are oily protective substances or soft sebum and the like inside the finger, and during application, sebum and the like easily deform together with the outer surface (surface of the skin) and modify the shape, following the application surface, whereby the fingers can apply a uniform pressure on the application surface on the contact width. .25 The soft sebum is an elastic body but is able to deform in accordance with the pressure. [0019] (b) There is the phalanx bone and the nail on the back side of the outer skin and sebum. At the time of application, the nail and bone will not bend and deform, and thus the outer skin and sebum deform according to the application surface to be covered. [0020] (c) The width of the nail is narrower than the width of the finger so that when the liquid is applied by taking advantage of the deformation of the skin and sebum, the nail will never come into contact with the application surface even when the finger is inclined, and it will not scrape the applied liquid from the application surface. (D) The surface of the skin is non-absorbent or will not absorb the liquid, so the composition of the liquid will not change. (E) When the application liquid is applied with the finger, the application liquid is directly delivered from the container to the finger or to the surface to be covered and is then spread with the finger. Therefore, it is not possible for the edge around the delivery hole of the container to scrape the application liquid. The inventors of the present have prepared applicators having the features and functions set forth above and have designed an applicator of the invention adapted to easily and uniformly apply an application liquid in a manner similar to the application with the fingers. The applicator of the invention is configured as follows: [0024] (1) According to the present invention, an applicator for applying application liquid to a surface to be covered by means of an applicator body, applicator comprising: an applicator body, comprising: a membranous portion which is easily deformable upon application of a liquid; and a cavity portion enclosed by the membranous portion, where when an explaining surface of the membranous portion comes into contact with a surface to be covered, the application surface of the membranous portion in contact with the application surface follows a contact surface of the application surface by a pressure of the membranous part acting on the contact surface of the surface to be covered. As described in support of the related Patent Documents, in the application of liquid with a usual application part formed by a type of soft elastic material, such as silicone rubber, sponge or the like suggested as part of conventional soft application, it is inevitable that the pressure acting on the application surface becomes higher at the deeper portion of the application portion so that the thickness of the application liquid will not be uniform relative to the sense of the width of the application part. Therefore, the problem mentioned above can be solved by an application part made of a soft deformable outer skin with a cavity portion (space) in which a load that can be deformed at the time of application is introduced or stuffed. The membranous part of the outer skin may be made of rubber (silicone rubber, urethane rubber, isoprene rubber (IR), butadiene rubber (BR), styrene butadiene rubber, chloroprene rubber (CR)) , acrylonitrile butadiene rubber (NBR), butyl rubber (IIR), ethylene-propylene rubber (EPM), chlorosulfonated polyethylene rubber (CSM), acrylic rubber (ACM), fluororubber (FKM), rubber natural and other) so as to make it fine and mine and so that it can easily deform. For the rubber of the outer skin, it is necessary to select a rubber with a hardness easy to handle depending on the application liquid. The hardness of the rubber is preferably from 20 to 60. A rubber with a rubber hardness of less than 20 is soft and easily deformed, but tends to break. A rubber with a rubber hardness exceeding 60 can not provide sufficient deformation and it is therefore difficult to render the application liquid uniform in thickness. The hardness of the rubber is more preferably 20 to 40. [0028] The interior of the cavity portion preferably contains a load which is not elastically deformed, but which deforms easily and does not have a great repulsion. The load does not need to be introduced or fully loaded so that the outer skin will be in a pressurized state to have a defined tension, but it is preferably loaded so that the outer skin will be more or less relaxed or relaxed, like a finger. [0029] (2) In the present invention, it is preferable that the cavity portion contains a substance that forms a soft gel after introduction by a crosslinking reaction. When a gelatinous material is introduced or stuffed as a filler into the cavity portion (the inside of the outer skin), the pressure acting when the liquid is applied becomes approximately uniform. Therefore, it is possible to apply the liquid in a uniform thickness. When, for example, a two-component liquid reaction silicone or the like is used as a gelatinous material, the two liquids can be loaded into the outer skin and subsequently made to form a soft gel by crosslinking. In this case, the liquid silicone and the like are loaded into the cavity portion to adjust to the inner shape of the outer skin, and then crosslinked to form a gel. Due to gel-like physical properties, the charge will not flow easily through the fill hole although pressure is applied during application so that it is not necessary to seal or seal the filling hole. As a result, the production of the application body can be simplified. The gel-like material preferably has a hardness (penetration) of 30 to 90. [0034] (3) In the present invention, it is preferable that the cavity portion contains a foamable substance after filling for form a soft sponge. The introduction of soft spongy material into the outer skin also provides an advantage of the present invention. In this case, a spongy substance of the reaction type, such as urethane foam, is caused to react within the cavity portion so as to completely fill the hollow portion without the load spilling out of the filling hole. when the applicator is used for the application. As to the appropriate hardness of the sponge, it preferably has a repelling force of 10N to 350N when a test piece of the sponge with a length of 390 mm, a width of 390 mm and a thickness of 50 mm is compressed by 25%. (4) In the present invention, it is preferred that the cavity portion contain a filler that has been made viscous by a thickener. When using a thickener to form a gel-like filler and to fill the cavity portion, the agent couples with the filler due to gravity to form a gel-like clump. The use of various types of thickeners, either water-based or oil-based, facilitates the production of gel-like fillers of flexibility or softness different. Since the thickener can be selected, the use of a thickener for food or cosmetic purposes is able to ensure safety even when the contained or contained liquid leaks and comes into contact with the body of the user. (5) It is preferable in the present invention for the cavity portion to contain air, and the air is retained in a sealed manner in the cavity portion by adjusting the thickness of the membranous portion, or a shape of the cavity portion is maintained due to an elastic force of the membranous portion in a state where the air is not sealed in the cavity portion. When the air can be used as the charge of the cavity portion (the inside of the outer skin of the membranous portion), it is possible to reduce costs. In particular, it is not necessary to keep the air inside the cavity portion if the thickness and the internal space of the outer skin are adjusted so as to provide an appropriate pressure when the application body is subjected to pressure for application. However, in this case, the application body must return substantially to its original shape after use because of the elasticity of the outer skin. It goes without saying that there is no problem in using a type in which the cavity portion is sealed to prevent air leakage.
    [0002] Similarly, in this case, it is preferable that the air is not fully charged so that the charged air will exert pressure on the outer skin, but is loaded so as to create more or less releases. (6) In the present invention, it is preferable that a liquid dispensing hole is arranged in a zone other than the application surface of the application body. The provision of a liquid distribution hole in the zone other than the application surface makes it possible to eliminate unevenness of application as a result of the scraping of the liquid during application by the part surrounding the dispensing hole. liquid. (7) In the present invention, it is preferable that the application body is made with a rigid portion which has greater rigidity than the side of the application surface and is arranged on an opposite side of the application surface with respect to a liquid flow passage so as to prevent overall distortion of the application body during application of the liquid. When the entire application portion is made by an outer skin and a load, it is difficult to easily and uniformly apply the liquid over a wide area because the application body is curved everywhere at the time of the application of the liquid. In contrast, when using the finger for the application, the finger has a nail and bone that support the application portion (that is to say the pad or finger pulp) formed by skin and sebum, allowing the finger to perform an easy application of the liquid. To obtain that the application body produces the same effect as a finger, it is necessary to provide a rigid portion on the opposite side of the application portion formed by the outer skin and the load. The structure for imparting rigidity to the application body may be configured by thickening the opposite side of the soft elastic material (rubber) forming the outer skin of the application portion to impart rigidity, or by arranging a molding in resin, metal part or the like on the opposite side of the application part in order to impart rigidity in the assembly. Here, a through hole for the delivery or distribution of the liquid may be formed in a reinforcing portion to provide rigidity, and this rigidity allows the user to dispose or place the liquid at a desired position in a manner easy and reliable. (8) In the present invention, it is preferable that the application body is formed so that the side of the application surface is wider than the rigid portion, in a cross-sectional view, perpendicular to the flow passage of the liquid. To spread the liquid uniformly, it is important that the soft deformable application surface alone comes into contact with an application surface to be covered. If the application takes place while the portion (rigid portion) made to make the rigid application body comes into contact, the applied liquid is scraped by the spreading performance so that the application in a uniform thickness can not not be reached. To solve this problem, the application surface must be formed so as to spread outside beyond the rigid portion when the liquid is applied. Specifically, when the application portion is viewed from above (on the rigid portion side), it is necessary that the soft application portion be visible outside the rigid portion. [0055] (9) In the present invention, it is preferable that the application surface of the applicator body is made by a non-absorbent surface. When the outer skin of the application surface is non-absorbent, the application surface will not only absorb the solvent component, which tends to be absorbed, the liquid to be applied, and there is therefore no risk that the composition of the liquid varies. [Advantages of the Invention] According to the applicator of the present invention, the applicator body is formed so that when the membranous application surface comes into contact with the surface to be coated, the contact surface membraneuse is deformed following the surface to be covered by the pressure acting on the contact surface. As a result, this application body can produce an excellent advantage during the application of the liquid by pressing the applicator body onto the surface to be covered, that is to say that it is possible to apply the liquid - regularly in a uniform thickness even if the surface to be covered is curved. 10058] The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying drawings given solely by way of example illustrating several modes. embodiment of the invention and in which: - Figure 1A is a side view of an applicator according to a first embodiment of the present invention; FIG. 1B is a side view of the applicator including a vertical cross sectional view taken along the plane A1-A2 of FIG. 1A; FIG. 1C is an enlarged vertical cross-sectional view taken along the plane A1-A3 of FIG. 1A; FIG. 2A is a front view showing an applicator body made for an applicator according to a second embodiment of the present invention, seen from one side of the delivery port; FIG. 2B is a vertical cross sectional view taken along a plane B1-B2 of FIG. 2A; FIG. 2C is a perspective view showing the application body according to the second embodiment; FIG. 3A is a front view showing an applicator according to the second embodiment, seen from a cap side 2; FIG. 3B is a vertical cross sectional view of the applicator assembly, taken along the plane C1-C2 of FIG. 3A; FIG. 3C is an enlarged cross-sectional view showing the applicator body and its surroundings of FIG. 3B; FIG. 4A is an illustrative view showing a state of use of the applicator, based on the vertical cross sectional view of the applicator body taken along the plane D1-D2 of FIG. 2B; FIG. 4B is an illustrative view showing a state of use when the application body of FIG. 4A is inclined; and FIG. 4C is a view in vertical section of a variant of the application body represented in FIGS. 4A and 4B. Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
    [0003] Hereinafter, FIGS. 1A to 1C, FIGS. 2A to 2C, FIGS. 3A to 3C and FIGS. 4A to 4C may also be mentioned as FIG. 1, FIG. 2, FIG. 3 and FIG. 4, respectively. Figure 1 is an illustrative view of the applicator according to the first embodiment of the present invention. The applicator according to the first embodiment is an applicator for applying an application liquid to a surface of an application object by means of an application body 10. The application body 10 possesses a membranous portion 12 which is easily deformed at the time of application and a cavity portion 14 enclosed by the membranous part. The applicator body 10 is configured so that when an application surface 12a of the membranous portion 12 comes into contact with the application surface to be covered, a contact surface of the membranous portion 12 adjusts closely to following a contact zone of the application surface due to the pressure of the membranous part 12 on the contact area of the application surface to be covered. Specifically, as shown in FIG. 1, the applicator body 10 is formed by the membranous portion 12, as an outer skin, and the cavity portion 14 alone, and is a flexible bag-shaped molding having a front portion approximately spherical and a cylindrical rear part. The applicator body 10 is configured as simply as the front part acts as an application part 10a, which is fed with liquid and brought into contact with the surface to be covered, thus being able to execute the application. The rear cylindrical portion of the applicator body 10 is fixed on a front end of a cylindrical drum 16. The membranous portion 12 of the applicator body is made of rubber (for example silicone rubber) while the cavity portion 14 of the applicator body 10 is filled with a readily deformable soft substance such as a gel (liquid silicone), sponge or the like, or air, to form the soft application portion 10a. The applicator according to the second embodiment will now be described. Figure 2 is the illustration of the application body used for the applicator according to the second embodiment. Figure 3 is the illustrative view of the applicator as a whole. Fig. 4 is the illustrative view showing states of use of the applicator. As shown in FIG. 2, an application body 10 according to the second embodiment comprises: a membranous part 12 forming an application surface 12a; a stiff reinforcement portion 18 made thicker than the application surface 12a; and a liquid dispensing or dispensing hole 20 formed between the two preceding parts. The rigid reinforcing portion 18 is formed at the opposite side of the application surface 12a of the membranous portion 12 relative to the liquid delivery hole 20. The reinforcing portion 18 is made such that the application body 10 in its assembly will not deform when the applicator is used for the application. The applicator body 10 is molded from liquid silicone (either a type of LIM or a type to grind can be used). Fig. 2 shows the configuration of the outer skin of the membranous portion 12. [0068] The applicator body 10 can be molded into a grindable type so that the membranous portion 12 of silicone rubber has a thickness of 0.4 mm and a rubber hardness of 20, 30 or 40. As for the operability, the softer the rubber, the more a flexible and comfortable feeling can be obtained when the applicator is used. As shown in Figure 2, in the application body 10, the thin membranous portion 12 forms an application portion 10a within which a hollow portion or cavity 14 is formed. As shown in Fig. 2A, the curved surface in the bottom side front side view has a radius of curvature R1 which is smaller than the radius of curvature R2 of the curved surface on the upper side seen from the front side. As a result, the curved surface on the lower side inflates further to simulate a human finger. The lower side portion having the radius of curvature R1 is the application portion 10a of the membranous portion 12 having the cavity portion 14. On the other side of the application portion 10a (the curved surface having the radius of curvature R2) constitutes the thick reinforcement portion 18, the thickness of the rubber of the reinforcing portion 18 being greater than that of the membranous portion 12. The application portion 10 is entirely formed of soft rubber, but the portion of reinforcement 18 is thicker than the application portion 10a so that the upper side forming the reinforcing portion 18 produces rigidity. Here, as shown in FIG. 2, the application body 10 is configured such that the application portion 10a is made of a diameter that is thicker than the cylindrical portion, designated C, to be coupled with the barrel or cylinder 16 (Figures 3B and 3C) located in the back of the applicator body, so the application portion 10a is formed into a wide area for easy application. The liquid dispensing or dispensing hole (liquid flow passage (20) is formed between the application portion 10a and the reinforcing portion 18. Since the opening of the liquid dispensing hole 20 is away from the application portion 10a, this arrangement is advantageous or makes it possible to prevent the portion forming and surrounding the liquid distribution hole from scraping the liquid applied during the application of the liquid. [0071] To obtain a more stable rigidity it is possible to insert a resin molding or a metal part (metal tube, stainless tube) into the reinforcing part 18 (rigid part) made of rubber. [0072] FIGS. 3B and 3C show a configuration of an applicator wherein a stainless tube 22 is inserted as a reinforcing member in the applicator body 10, particularly in the liquid dispensing hole 20. Alternatively it is possible to fix the application part 10a on a reinforcing element. That is, to provide the necessary rigidity, a rubber molding to form an application portion 10a of a membranous portion and a cavity portion may be attached to a resin molding or a metal portion (essentially forming a reinforcing portion) to construct an application body provided with rigidity. In a manner similar to the first embodiment, the introduction of an easily deformable substance in the cavity portion 14 inside the outer skin allows to perform an unequal application of the liquid without causing the outer skin to produce uneven pressure during spreading of the application liquid. Figures 3B and 3C show the applicator wherein a hard tube 22 of stainless steel or the like is inserted into the liquid dispensing hole 20 to make the entire application body 10 more rigid. Inside the barrel or cylinder 16 is arranged a reservoir (container) 24 for the storage of a liquid, a piston 26 and a feed mechanism 28 which advances the piston 26 to bring the liquid from the reservoir The plunger 26 has a structure which has a soft outer peripheral portion disposed and slidable a liquid impervious contact with the inner wall of the reservoir 24 to bring the liquid to the application body 10. [ The advancement mechanism 28 comprises a control handle 30 at the rear end of the barrel 16 and a feed cylinder 32 which is fixed with respect to the direction of rotation of the handle 30 and arranged inside the housing. 16. In the feed cylinder 32 is arranged a threaded rod 34 for advancing the piston 26 so that the rod 34 is retained against rotation and can move freely in the directions of advancement and of retirement it. The threaded rod 34 has a varied external force and a male thread. Inside the barrel 16 is fixed a threaded body 36. The threaded body 36 is configured to engage a female thread formed inside the threaded body 36, with the threaded rod 34. The piston 26 is adjusted by A rotating manner at the front end of the threaded rod 34, so that the piston 26 propels the liquid in the reservoir 24 vent the application body 10 as the threaded rod 34 advances. The cylindrical portion C in the rear portion of the applicator body 10 is fitted into a front barrel 38 (FIG. 3C) which is inserted into and fixed to a hinge 40 at the front end of the barrel 16. [0079] The applicator shown in Fig. 3 has a liquid delivery hole 20 which is connected to the reservoir (container) 24. This liquid delivery hole 20 is arranged at the top of the application portion 10a, in the zone other than the application surface 12a. A necessary amount of liquid is removed and placed on the surface to be covered by the liquid distribution hole 20 by means of the feed mechanism 28, after which the liquid is spread by rubbing the liquid with the application portion 10a. Here the applicator shown in Figure 3 is constructed such that a cap 42 is removably fitted to the front end of the barrel 16 when the applicator is not in use. When the applicator body 10 is not in use, the applicator body 10 is covered by the cap 42 so as to prevent drying of the liquid delivery hole 20 and the application surface 12a of the body. application 10, thus ensuring a regular application of the application liquid during the next use of the applicator. In the present embodiment, the liquid distribution hole 20 is not formed in the application surface 12a. There is therefore no risk that the liquid delivered from the liquid-dispensing hole 20 is scraped immediately by the structure forming the liquid-dispensing hole 20. Therefore, the liquid can be applied in a uniform thickness and / or in a uniform width. In the application body 10, the cavity portion 14 is open towards the rear (opening 14a), as shown in FIG. 2. That is, since the core is removed. when the application body 10 is molded, the opening 14a is inevitably formed. However, the use of a gelatinous material which reacts and crosslinks with a liquid silicone or the like, as a charge to be introduced into the cavity portion 14, prevents the charge from being expelled from the opening 14a on the back side. In a similar manner, when a sponge, such as foam urethane or the like, is loaded into the cavity portion 14 of the outer skin (application surface 12a) and then made to foam, the sponge will not be expelled from the opening 14a when the applicator is used. [0083] Alternatively, when a gelatinous material is prepared using a thickener such as guar gum or the like and loaded into the cavity portion 14, the material is molded to fit the inner shape with time. after filling or introduction, so that the material will not be expelled through the opening 14a. The ease with which the load is expelled from the opening 14a when the applicator is used differs depending on the viscosity. When a gelatinous thickener is used, there is a risk that the base liquid (solvent) will evaporate, and the gel volume may decrease. In this case, the mouth (opening 14a) needs to be sealed. On the other hand, if the cavity portion 14 is not filled with a soft material, or if the application portion 10a which is not filled with a load is used such that, this configuration is economic. In this case, the elasticity can be adjusted by the thickness of the membranous portion 12 and the selection of the rubber material. The use of the application portion 10a with its unchanged cavity can be accomplished by sealing the opening 14a of the cavity portion 14 within the application portion 10a. The air inside does not need to be pressurized. Although the application portion is more or less soft or flaccid, there will be no problem as long as the application portion is under 'voltage' when it is used. Alternatively, the thickness of the outer skin rubber (the thickness of the membranous portion 12) can be increased to increase or slightly increase the rigidity, and thus it is possible to obtain a usable configuration even if the opening 14a of the cavity portion 14 within the membranous portion 12 (outer skin) is connected to the atmosphere. [0088] The conditions of the applicator body during use will now be described. When the application part 10a during the application is seen in section, as shown in FIG. 4A, there are two parts, the part of the application surface 12a (application part 10a) of the body 10 and the crest portion or thick edge (reinforcing portion 18). The cross section of each zone will be taken into consideration. The covered area of the applied object is indicated by H (FIGS. 4A and 4B). An additional line A (FIGS. 4A and 4B) is drawn in the width direction of the application body 10 so as to pass through the liquid distribution hole (liquid flow passage) 20 while another line additional B (Figures 4A and 4B) is drawn in the direction of the thickness. In the application body 10, in the case where the cross section of the application portion 10a including the cavity portion 14 is approximately the same as the cross section of the reinforcing portion 18, when the body 10 is placed with the application surface 12a inclined relative to the surface H of the object to be covered, the corner of the reinforcing portion 18 comes into immediate contact with the area in which the liquid is spread on the surface to cover because the cross sections of the application portion 10a and the reinforcing portion 18 are equal to each other as shown in Fig. 4B. As a result, the rigid wedge can scrape the liquid from the covered surface, leading to the risk that the application of the liquid becomes uneven and causes a lack of uniformity in width. To remedy this situation, a variant of the application body 10 is shown in Figure 4C. An applicator body 10 in Fig. 4C has a configuration in which the cavity portion 14 within the outer skin extends toward (spreads into) the reinforcing portion, forming extended cavity portions. 14b. In this arrangement, the extended cavity portions 14b are hollow so that the width of the application portion 10a having extended cavity portions 14b is greater than the width of the rigid solid portion 18, relative to the width direction. A. That is, the expanded cavity portions 14b that are softer and more resiliently deformable than the corner of the rigid portion 18 are formed outside the rigid portion relative to the width direction A. Therefore, the corner of the rigid portion (reinforcement portion) 18 does not approach or come into contact with the surface to be covered H of the applied object even if the liquid is applied with the inclined application body. As a result, the applied liquid will not be scraped off, or will not tend to be scraped off. It should be noted that the present invention is not limited to the embodiments described above, but various changes and modifications can be made to the scope of the invention. For example, a tube may be inserted as a reinforcing member in the application body. Or a two-color molding can be used to form a reinforcing part.
