    [0001] The present invention relates to an applicator of the feed type provided with an application portion covered by a cap. Conventionally, there have been applicators that have a writing tip sealed by a sealing member arranged on a cap when the cap is put in place, as disclosed in Patent Documents 1 When these applicators are used with a highly viscous or adhesive liquid, there is a risk that the writing tip and the sealing member will stick to one another causing the removal. or the displacement of the sealing member. To solve this problem, it is necessary to take measures to prevent the sealing element from being removed by improving the force of the engagement between the sealing element and the fastening element for the element. sealing; [0004] With respect to these countermeasures, there has been a method disclosed in Patent Document 3, wherein an inner cap is fitted from the back side to be secured within the cap. However, in the cap for a writing instrument of this Patent Document 3, a screw-in crown is fitted from the front side of the cap into the inner cap and is engaged therewith to retain and to fix a sealing element between the inner cap and the screw-in crown. In another configuration, when a sealing member is secured using an inner cap, undercuts (see Patent Document 5) or a face cut is used to secure a sealing rubber. In this case, if the tip of the application portion comes into liquid contact with the sealing rubber and sticks, the bonding can produce a greater bonding force than the fixing force, bringing the sealing rubber to be removed from the cap. When undercuts and a face cut are used to improve the strength of resistance, the realization of adjustment margins exceeding a predetermined amount is considered impossible because the assembly of the sealing rubber in the inner hood becomes unfeasible. When other methods of attachment than those of the undercuts and the face cut are examined, the fixing of the sealing element is performed by adjustment methods as in Patent Document 1. However, the method described in Patent Document 1 uses a sealing element of a complicated configuration so that the use of a thermoplastic elastomer is required, thereby resulting in additional steps and effort as well. application of heat and the like.

Embodiments of the present invention will now be described with reference to the accompanying drawings. Figures la to 5b are illustrative diagrams of an applicator provided with the cap according to the first embodiment of the present invention. Here, in the description which follows, FIGS. 1a and 1b can also be collectively referenced as FIG. 1. FIGS. 2a and 2b can also be collectively referenced as FIG. 2. FIGS. 3a to 3h can also be collectively referenced as FIG. FIGS. 4a to 4f can also be collectively referenced as FIG. 4. FIGS. 5a and 5b can also be collectively referenced as FIG. 5. The applicator according to the first embodiment is a feed or click supply container which is capable of supplying or delivering contents following pressure on a click cover 12 arranged at the rear end of a barrel body (barrel cylinder) forwardly in the axial direction, such as represented in FIG. 1. In the following description of the applicator of FIG. 1, the side of the cap 28 will be referenced as the front side by reference. t to the direction of extension (axial direction) of the axis of the applicator, while the side of the cover to click 12 will be designated by back side with respect to the axial direction. The applicator comprises a click mechanism A for converting the pressing force of the click action exerted by the user acting on the lid to click 12 in rotation force, a threaded body 14 fixed to the body of barrel 10 (barrel cylinder) and a threaded rod 16 matched with the threaded body 14. The rotational force converted by the clipping mechanism A rotates the threaded rod 16, and thereby the threaded rod 16 advances through the body threaded 14 so as to push a resilient or resilient piston 18 at the front end of the threaded rod 16 for the supply of the contents of a reservoir 20. Here are attached to a front end portion 10a of the body barrel 10 a seal 22, an application portion 24 and a front barrel 26, as shown in Figure 1b. The contents (a liquid or fluid such as flowable makeup in the present embodiment) fed from a reservoir 20 of the barrel body 10 is dispensed from the tip to the front side of an application portion 24. [0022] The applicator of the first embodiment has a removable cap 28 which completely covers the application portion in the front portion of the applicator. When this cap 28 is adjusted or put in place, the front end on the front side of the application portion 24 is sealed by a sealing member 30 (Figure 1b). When the applicator is used, the cap 28 is removed so as to expose the application portion 24, allowing writing or tracing. When the applicator is not used after tracing, the cap 28 is fitted to the front end of the barrel body 10 so that a waste of the contents of the application portion 24 is prevented by the element. Sealing 30. The barrel body 10 comprises the front end portion 10a on the front side in the axial direction, the front end portion 10a having a stepped shape whose diameter becomes smaller towards the front side . The cylindrical seal 22 is fitted in the front end portion 10a. The seal 22 and the front end portion 10a are covered by the front barrel 26. The tube-like application portion 24 is supported by the front interior of the front barrel 26 and the front portion of the seal 22 (Fig. 1b ). In this arrangement, the cap 28 can be adjusted to cover the application portion 24 and the front barrel 26 (Figure lb). The click mechanism A may have any configuration to the extent that it is able to advance the piston 18 to the front side when a thrust is exerted on the cover 12 to be clicked by way of example , the click mechanism A disclosed in Japanese Patent Application Laid-Open 2010-88793 can be used. In the clipping mechanism A, a rotation body 32 is assembled inside the threaded body 14, the rear portion of which extends in a cylindrical manner while the threaded rod 16 is inserted through the axial center. . The click cover 12 is rotatably arranged at the rear end of the rotation body 32 and can not move in the axial direction. The rotational body 32 has an annular configuration in which a first forward cam surface is formed at the front end, and a second rearward directed cam surface is formed on the outer periphery in the middle portion. and is rotatably and axially displaceable within the barrel body 10 and the threaded body 14. The threaded body 14 includes a stepped tubular portion of a small diameter in the end before, provided with a female thread in the bore therein, and a first stationary cam surface in the rear face of the tubular portion. A cam body 34 is assembled within the rear tubular portion of the threaded body 14 to cover the rotational body 32 and includes a second stationary cam surface formed on its front end. The threaded body 14 and the cam body 34 are fixed in the direction of rotation and the axial direction relative to the barrel body 10. A spring 36 urging the body of rotation 32 rearward (towards the rear side ) is arranged in the threaded body 14. When the user clicks on the click cover 12, the first cam surface of the rotation body 32 meshing with the first fixed cam surface of the threaded body 14 is guided along teeth of the first stationary cam surface due to the pressing force opposing the spring 36, and thereby the rotation body 32 advances (towards the front side) by turning in the predetermined direction of rotation according to a tooth . On the other hand, when the pressure force is canceled, the rotation body 32 moves back due to the repulsion force of the spring 36, and the second cam surface meshes with the second stationary cam surface of the body. cam 34 so that the second cam surface is guided along the tooth, and thereby the rotation body 32 moves back (towards the rear side) by turning in the predetermined direction of rotation according to a tooth. The click mechanism A is configured to produce rotational movement by the cams, as above. The rotation of the rotating body 32 causes the threaded rod 16 to rotate to advance the piston 18 to the front side by means of the threaded body 14 and thus distributes the contents. Figure 2 shows the cap 28, Figure 3 shows an inner cap 38 in its closed state, Figure 4 shows the inner cap 38 in its open state, and Figure 5 shows the cap 28. [0036] shown in FIG. 2, the cap 28 completely covers the application part 24 (FIG. 1b) in the front part of the applicator and seals the end end portion of the application part 24 with the element sealing 30 when the cap 28 is attached to the applicator (Figure lb). The inner cap 38 is inserted into and attached to the inside of the cap 28 (Figure 2). As shown in FIGS. 3 and 4, the inner cap 38 is configured so that a hollow hinged cap 42 is joined to an inner cap body 38a by a band-shaped foldable hinge structure 40. [FIG. As shown in FIG. 5, a plurality of projecting engagement portions 44 (FIGS. 2b, 5a and 5b) for securing the hinged cap 42 are formed within the cap 28. [0040] The inner cap body 38a includes a rear part of a large diameter. The hinge structure 40 is formed contiguously in the portion of the outer periphery of the rear portion. The inner cap body 38a is joined to the hinged cap 42 by the hinge structure 40 (Fig. 3c). In the inner cap 38, the sealing member 30 is placed inside the inner cap body 38a, then the hinge structure 40 is bent so that the hinged cap 42 abuts against the side of the inner cap body 38a. rear opening of the inner cap body 38a, whereby the sealing member 30 can be maintained in a predetermined condition within the inner cap 38. The cylindrical outer peripheral surface of the hinged cap 42 is conically formed , becoming progressively narrower from the front side to the back side.
    [0002] In addition, a flange-like protrusion 42d is formed along the front-end opening on the outer peripheral surface of the hinged cap 42 except for the position where the hinge structure 40 is connected or joined. Here, the configuration of the protrusion 42d is not limited to the flange shape but may be of any shape as long as it can be engaged with the engaging portions 44 described below. In addition, instead of producing the projection 42d, the outer peripheral surface of the hinged cap 42 may be tapered so as to engage engagement portions 44.
    [0003] That is, the hinged cap 42 can have any configuration as long as its outer peripheral surface can be engaged with the engaging portions 44. Within the hinged cap 42 is formed a hollow portion which is defined by a stepped portion 42a hereinafter which serves as a mounting portion for mounting the sealing member 30. On the rear side of the hinged cap 42 is formed an opening 42c which communicates with the portion hollow defined by the stepped portion 42a. When the inner cap 38 is inserted into the cap 28 with the sealing member 30 retained between the hinged cap 42 and the inner cap body 38a, the inner cap 38 moves to the front side while passing over the portions of the inner cap 38. engagement 44 (Figure 5) within the cap 28 until the rearward side of the projection 42d of the hinged cap 42 engages the front side of the engagement portions 44. Therefore, the inner cap 38 can be engaged and fixed inside the cap 28 (Figure 2b). That is, the rear side of the projection 42d engages the front side of the engaging portions 44 so as to prevent a fall of the inner cap 38 from the inside of the cap 28. sealing 30 is arranged to be visible through the circular opening 42c of the hinged cap 42 when the inner cap 38 has been inserted into the cap 28. Here, the opening 42c can have any configuration as long as the front end of the application portion 24 can pass through the hinged cap 24, and thus the size and shape of the opening 42c are not limited. In more detail, the cap 28 is a closed hollow cylinder on the front side and open towards the rear, as shown in Figures 2 and 5. As shown in Figure 5, the inside of the cap 28 is constructed such that the front portion has a slightly reduced inner diameter and enlarged to a stepped portion 28b. On the inner side, a plurality of insulated projections are formed at a rearward distance from the stepped portion 28b as engagement portions 44 located at the same position relative to the axial direction. During assembly, the front end of the inner cap 38 abuts the front end within the cap 28 while the rear side of the protrusion 42d on the outer peripheral surface of the hinged cap 42 in the The rear of the inner cap 38 interferes with the front side of the engagement portions 44, whereby the inner cap 38 is secured in the front end to the inside of the cap 28 so that the hinged cap 42 will not open. not. In addition, a protruding and serrated portion 28a formed by a plurality of continuous or discrete annular ribs is formed on the inner periphery in the rear of the engagement portions 44 and in the rear portion of the cap 28 (FIGS. 5). When the cap 28 is attached to the barrel body 10, the protruding and serrated portion 28a fits over the outer peripheral surface of the rear side of the front barrel 26 of the front end of the barrel body 10 so that the cap does not rotate. will not remove until a predetermined force is applied. Before the hinged cap 42 is closed, the inner cap 38 assumes a shape such that the cylindrical inner cap body 38a which is open at both ends is connected to the annular hinged cap 42 by the shaped hinge structure. 40, as shown in Fig. 4. The opposed surfaces of the inner cap body 38a and the hinged cap 42 are formed by surfaces having almost the same outer shapes. As shown in FIGS. 3 and 4, the inner cap body 38a has an outer peripheral configuration with a taper towards the front side, corresponding to the inner peripheral side of the cap 28. The inner peripheral wall in the back part of the body inner cap 38a is stepped for enlarging its diameter forming a mounting portion 38b (Figs. 2b, 3e, 4c-4f) to receive the sealing member 30 and has a plurality of projections. The inside of the hinged cap 42 on the front side also has a stepped portion (mounting portion) 42a (Figs. 3c, 4c-4e) forming a reduced diameter, such as an undercut. The inner cap 38 has an arrangement adapted to retain and secure the sealing member 30 without clearance or gap between the mounting portion 38b of the inner cap body 38a and the stepped portion 42a (Figs. 2 and 3e). The hinged cap 42 includes a hooking portion 42b which protrudes toward the front side in the axial direction, formed on the opposite side of the hinge structure 40 (Figures 2b, 3d to 3f and 3h). That is, when the hinged cap 42 is closed, the hooking portion 42b abuts against the inner cap body 38a along its outer periphery so as to position the hinged cap 42 with respect to the direction radial. The portion (38a) of the inner cap body 38a abutting the hooking portion 42b has a flat surface (Figs. 3f and 4f). The inner cap body 38a, the hinge structure 40 and the hinged cap 42 of the embodiment may be made with resins (or partially with metals) which are selected as appropriate. For example, these components may be made integrally of the same material, may be separately formed of different materials and connected by a hinge structure, may be formed by two-color molding of different materials, or may be formed by n any other method, as appropriate. The sealing element 30 has a sectional configuration H formed by integrating a cylinder and a membrane therein (FIGS. 2 and 3). This is just an example. The sealing member may be a thick, spherical plate or any other shape. The sealing member 30 is preferably made of resilient elastomers such as NRB (nitrile rubber); EPDM (ethylene-propylene diene rubber), thermoplastic elastomer, silicone resin and the like, by selection as appropriate depending on the application liquid material and other factors. The application portion 24 (Fig. 1b) of the embodiment has a tube-like configuration. When the cap 28 is fixed, the tip of the application portion 24 passes through the opening 42c of the hinged cap 42 and pushes the membrane of the sealing member 30 so that the membrane is extended and is deformed to the front side while sealing the opening at the tip of the application portion 24. Therefore, when the cap 28 is attached to the front barrel 26, the sealing member 30 comes into close contact with the opening at the tip of the application portion 24 to thus permanently prevent a flow of the application liquid. The transverse surface of the opening of the application portion 24 is preferably 0.2 mm 2 or larger. The position of the sealing member 30 within the inner cap 38 with respect to the axial direction can be arbitrarily selected within a range in which the above operation and effect can be achieved when the cap 28 is put in place. [0049] The application liquid to be applied by the applicator preferably has a solids content of 5% by weight or higher as a coating or coating component. According to the applicator according to the first embodiment, when the inner cap 38 is installed in the cap 28 with the sealing member 30 retained between the hinged cap 42 and the inner cap body 38a by bending of the articulated cap at the hinge structure 40, the hinged cap 42 can be engaged and fixed with the engagement portions 44 within the cap 28. Since the sealing member 30 is arranged to be visible from the rear side of the hinged cap 42 through the opening 42c of the hinged cap 42, it is possible to obtain excellent operation and effect by securely fixing the sealing member 30 with a simple configuration. [0051] Now an applicator with a cap according to the second embodiment will be described with reference to Figs. 6a to 8g. In this case, the same components as those of the applicator of the first embodiment will be designated by the same reference numerals. Here, in the description which follows, FIGS. 6a and 6b can also be collectively referenced as FIG. 6. FIGS. 7a to 7i can also be collectively referenced as FIG. 7. FIGS. 8a to 8g can also be collectively referenced as FIG. As shown in FIGS. 6 to 8, in the applicator according to the second embodiment, an engagement structure 46 (FIGS. 7f and 7g) is formed between the hinged cap 42 and the inner cap body 38a. . With the sealing member 30 retained therebetween, the hinged cap 42 is bent at the hinge structure 40 so that the hinged cap 42 and the inner cap body 38a can be engaged with the hinge plate 40. with the engagement structure 46. [0053] Specifically, the engagement structure 46 includes projections 46a on the side of the hinged cap 42 and ribs 46b on the side of the body of the hinge 46. inner cap 38a.
    [0004] As for the projections 46a on the side of the hinged cap 42, the hooking portion 42b of the hinged cap 42 has a rounded semi-cylindrical projection 46a projecting in the width direction on both sides relative to the width direction, as represented on a larger scale in FIGS. 7g and 8g (FIGS. 8d to 8g). As for the ribs 46b on the side of the inner cap body 38a, the inner cap body 38a being closed by the hinged cap 42, the circumferentially extending ribs 46b oppose the projections 46a so as to come into contact with each other. engagement with the outer peripheral side of the projections 46a are prominently formed at opposite positions of the inner cap body 38a (Figs. 7g, 8d, 8e and 8g). When in accordance with the second embodiment the hinged cap 42 abuts against the inner cap body 38a, the projections 46a engage with the ribs 46b so that the hinged cap 42 is attached to the opposite position to the body inner cap 38a to thereby prevent the hinged cap 42 from opening. Therefore, since the hinged cap 42 will not open, the sealing member 30 being retained in the inner cap 38, it is unlikely that the sealing member 30 will move or be dislodged when the inner cap 38 is fitted into the cap 28, thereby facilitating assembly. In addition, the engagement structure 46 increases the resistance to loosening or release of the hinged cap 42 after assembly so that the attachment of the sealing member 30 can be further increased. The present invention should not be limited to the first and second embodiments described above, but various changes may be made within the scope of the invention. For example, as to the sealing element, other than that described in the first and second embodiments, an embodiment variant 1 shown in Figures 9a to 9h and an alternative embodiment 2 shown in Figures 10a to 10h can be adopted. Here, in the following description, FIGS. 9a to 9h can also be collectively referenced as FIG. 9. FIGS. 10a to 10h can also be referenced collectively as FIG. 10. FIG. 9 is an illustrative diagram showing an inner cap 38 with a sealing member 30A retained therein according to an alternative embodiment 1, the sealing member 30A being retained between the inner cap 38 and the hinged cap 42. Fig. 10 is an illustrative diagram showing an inner cap 38 with a sealing member 30B retained therein according to another alternative embodiment 2, wherein the sealing member 30B is retained between the inner cap 38 and the hinged cap 42. The same components as those of the inner cap in the second embodiment are designated by the same reference numerals. As shown in FIG. 9, the sealing component 30A according to the embodiment variant 1 has a solid and approximately cylindrical or solid configuration and is similar to a button so as to wind up the application part 24 that goes into inside but when the tip of the application part is pushed inwards, thereby preventing leakage of the application liquid from the application part 24. The sealing element 30A according to the Embodiment 1 is sufficiently thick to receive the application portion 24 compared to the sealing elements 30 in the first and second embodiments, so that its endurance or service life is high. In addition, the sealing element has a simple shape and can therefore be easily formed. As shown in FIG. 10, the sealing component 30B according to the embodiment variant 2 has a solid and approximately spherical configuration so as to wind the application part 24 that goes into the interior even though the tip of the application part is strongly pushed in the interior, and it thus becomes possible to prevent leakage of the application liquid from the application portion 24. The sealing element 30B according to the embodiment variant 2 is thick enough to receive the application portion 24 compared to the sealing members 30 in the first and second embodiments, so that its endurance is high. In addition, the sealing member 30B is spherical, so it can be formed easily. On the other hand, the sealing member 30B is spherical so that the sealing member can be positioned simply by dropping it without special positioning on the mounting portion 38b being necessary when the element is placed on the inner cap 38. Therefore, this sealing element can be assembled more easily in comparison with that in the first and second embodiments and in the embodiment variant 1. The applicators of the present invention can be applied to writing instruments and various applicators for the correction of liquids, cosmetics etc. A click mechanism 10 barrel body 18 piston reservoir 24 application part 20 28 cap 28a protruding portion and rear serrated 28b stepped portion 30 sealing member 38 inner cap 38a inner cap body 38b mounting portion structure articulation 42 articulated cap 42a stepped portion (mounting portion) 42b engaging portion 5 42c aperture 42d protruding 44 engaging portion 46 engaging structure 46a protruding 10 46b rib 19
