Description

  The present invention relates to an applicator for applying a coating material.

  Conventionally, as an applicator, for example, the one described in JP-A-2005-87433 is known. In this publication, a cosmetic container containing a cosmetic, a shaft cylinder positioned in front of the cosmetic container, a tubular mouth end connected to the shaft via a spring, and a inside of the mouth end are provided. Described is a cosmetic applicator including a bottomed cylindrical application member that is housed and projects forward from the mouth end.

  Inside the cosmetic applicator, a cosmetic inflow portion, a second valve chamber, and a first valve chamber are provided in this order from the rear, and a space between the cosmetic inflow portion and the second valve chamber is provided. A second valve body is interposed between the first valve body and the second valve chamber, and the first valve body is interposed between the second valve chamber and the first valve chamber. The first valve chamber communicates with the internal space of the coating member. Further, the application member is provided with a plurality of ejection holes for ejecting the cosmetic material therein and a brush located between the plurality of ejection holes.

  In this applicator, the cosmetic material is filled in the cosmetic material inflow portion, the second valve chamber, the first valve chamber, and the inside of the application member. When the front end portion of the application member is pressed in this state, the mouth end portion moves backward with respect to the axial cylinder against the biasing force of the spring, the internal pressure of the second valve chamber rises, and the first valve body moves forward. Along with this, the cosmetic material flows forward from the first valve body and reaches the inside of the application member.

  At this time, since the cosmetic is discharged from the discharge hole of the application member and the cosmetic is supplied to the brush, the applicator can be used by applying the brush to the applied part such as the face. On the other hand, when the pressing on the front end portion is released, the mouth end portion advances and returns to the original position, the internal pressure of the second valve chamber is reduced, and the second valve body advances. Along with this, the cosmetic flows from the cosmetic inflow portion into the second valve chamber.

JP, 2005-87433, A

  The applicator as described above pours an application material such as a cosmetic material into the application member by pressing the front end portion of the application member. However, the pressing force applied to the front end of the coating member is not always constant, and a large amount or a small amount of the coating material may flow, which causes a problem that the discharge amount of the coating material is not stable. .. Further, in this type of applicator, the amount of the internal coating material gradually decreases while the user continues to use the applicator for a long period of time. As a result, the amount of the coating material supplied to the coating member is also reduced, which causes a problem that the coating material cannot be discharged in a fixed amount for a long period of time. Furthermore, the above-mentioned applicator employs a configuration in which the coating material is ejected from a plurality of ejection holes. Therefore, the coating material may be solidified in the discharge hole, and in this case also, the problem that the discharged amount of the coating material is not stable may occur.

  An object of the present invention is to provide an applicator that can stabilize the discharge amount of a coating material.

The applicator according to the present invention comprises a tubular container having a container for accommodating a coating material provided therein, and an applicator provided in the accommodating part and a rear side of the applicator in the container. A moving body connected to the cage applicator so as to be movable by a certain amount in the axial direction, and an applicator in which the applicator is pushed out from the front end of the container by advancing the applicator onto the surface of the applicator. Has a recessed portion that is exposed at the front of the container as the applicator advances, and the moving body is located in the accommodating part and moves forward with respect to the applicator to move the coating material in the accommodating part It has a押寄unit to concentrate on the front side, the mobile after a predetermined amount advanced relative coating material, advances along with the coating material.

  In this applicator, the applicator and the moving body that is connected to the applicator so as to be movable in the axial direction by a certain amount advance, and the applicator is pushed out from the front end of the container. The applicator body has a recess for containing the coating material on its surface, and this recess is exposed in front of the container as the applicator advances. Therefore, it is possible to expose the concave portion in a state where the coating material is stored in the concave portion and to make the application body usable. In addition, the moving body includes a pushing portion that pushes the coating material in the housing portion toward the front side of the housing portion by advancing with respect to the coating body. In this way, since the coating material in the housing portion can be concentrated on the front side by the pushing portion that moves forward with respect to the application body, even when the coating material in the housing portion is reduced, the coating material can be stably recessed in the coating material. Can be housed in. Therefore, even if the user continues to use the coating material for a long period of time, the coating material can be stored in the concave portion, so that the discharge amount of the coating material can be stabilized for a long period of time.

  The pushing portion is a protruding portion that projects radially outward on the front side of the moving body, and the outer diameter of the protruding portion may be smaller than the inner diameter of the housing portion and larger than the minimum outer diameter of the applicator. .. In this case, since the outer diameter of the pushing portion is smaller than the inner diameter of the accommodating portion, the pushing portion can be smoothly advanced. Furthermore, since the coating material can escape rearward from the gap formed between the pushing portion and the inner surface of the housing portion, it is possible to prevent excessive pressure from being applied to the front side of the housing portion. Therefore, it is also possible to appropriately concentrate the coating material on the front side of the housing portion.

  Further, the pushing portion may have a passage for passing the coating material from the front side to the rear side of the pushing portion. In this case, the pushing portion allows the coating material to be moved to the front side and part of the coating material to escape rearward from the passage. Therefore, it is possible to prevent excessive pressure from being applied to the front side of the accommodating portion, and it is possible to appropriately concentrate the coating material on the front side of the accommodating portion.

  Further, as a configuration that preferably achieves the above-described effects, specifically, the container includes a cylindrical container front part and a cylindrical container rear part, and the container front part and the container rear part are Is relatively rotatable in a direction, the container is provided with a screwing portion configured by a male screw and a female screw, the moving body, when the container front part and the container rear part are relatively rotated in one direction, There is a configuration in which the male screw and the female screw move forward by the action of screwing.

  Further, a plurality of screwing portions are provided in the container, and the moving body may advance by the screwing action of the plurality of screwing portions working together. When a plurality of screwing portions are provided in this way, the amount of movement of the moving body during relative rotation can be increased as compared with the case where there is one screwing portion. In addition, when a plurality of screwed portions are provided, the moving amount of the moving body can be secured even if the length of the container is short. It is also possible to shorten.

Also, moving body, before advancing with the coating material, since the relative movement forwardly relative to the coating material,押寄unit also moves relatively forward with respect to the coating material. Therefore, the coating material can be moved forward along the coating body while the pushing portion is moving forward relative to the coating body. Therefore, it is possible to easily store the coating material in the concave portion on the surface of the coating body.

  In addition, the applicator and the moving body are retracted from the state where the applicator is pushed out from the front end of the container, the applicator is immersed in the container, and the moving body is retracted by a certain amount with respect to the applicator, You may retreat with an application body. In this case, the applicator immerses in the container as it retreats. Therefore, for example, at the end of use, the applicator can be immersed in the container. Therefore, when not in use, it is possible to prevent the concave portion from being exposed by immersing the applicator body, and thus it is possible to avoid the application material from solidifying. Further, the position of the pushing portion can be surely returned to the state before use by moving the moving body backward relative to the application body. Therefore, the coating material can be reliably pushed forward by the pushing portion even when it is used next time.

  Further, the pushing portion comes into contact with a predetermined portion of the applicator when the moving body advances by a certain amount with respect to the application body, and the moving body advances by a certain amount with respect to the applying body, and then moves to a predetermined portion of the pushing portion. The application body may be pressed forward by the contact of 1 and moved forward together with the application body. In this case, both the function of pushing the coating material forward and the function of moving the coating body forward together with the moving body can be used as the pushing portion.

  According to the present invention, the discharge amount of the coating material can be stabilized.

  The operation when using the applicator 100 configured as described above will be described below. In the applicator 100 in the initial state shown in FIG. 1, the first screw cylinder 4, the second screw cylinder 5, the moving body 6, the first screwing portion 11, the second screwing portion 12 and The third screwing portion 13 is located at the rear end, and the rear ends of the first screw cylinder 4, the second screw cylinder 5 and the moving body 6 contact the bottom surface 3b of the operation cylinder 3. There is. The rear end of the enlarged diameter portion 7g of the applicator 7 contacts the front end of the first sealing member 8 to seal the insertion portion 8b of the first sealing member 8. Further, the first concave portion 7e and the second concave portion 7f of the application body 7 are located in the housing portion 2d inside the container body 2.

  In this state, for example, when the user relatively rotates the operation tube 3 in one direction (for example, clockwise) with respect to the container body 2, the female screw portion 3a of the operation tube 3 and the screwing protrusion of the first screw tube 4 are inserted. 4h, the screwing action of the first screwing portion 11 and the second screwing constituted by the female screw portion 4c of the first screw cylinder 4 and the screwing protrusion 5a of the second screw cylinder 5. The screwing action of the coupling portion 12 and the screwing action of the third screwing portion 13 constituted by the female screw portion 5c of the second screw cylinder 5 and the screwing protrusion 6c of the moving body 6 work. Then, the first screw cylinder 4 moves forward with respect to the operation cylinder 3 by the screwing action of the first screwing portion 11, and the first screw cylinder 4 with respect to the first screw barrel 4 by the screwing action of the second screwing portion 12. The second screw cylinder 5 moves forward, and the moving body 6 moves forward with respect to the second screw cylinder 5 by the screwing action of the third screwing portion 13.

  As shown in FIG. 2, the first screw cylinder 4 advances with respect to the operation cylinder 3, the second screw cylinder 5 advances with respect to the first screw cylinder 4, and the second screw cylinder 5 further advances. When the moving body 6 advances with respect to the cylinder 5, the moving body 6 advances without rotating with respect to the container body 2 because the protrusion 6d of the moving body 6 is non-rotatably engaged with the concave groove 2f. When the moving body 6 moves forward in the moving area 2e, the moving body 6 slides inside the insertion portion 8b of the second sealing member 9, and the protrusion 6a of the moving body 6 moves forward to move inside the housing portion 2d. The cosmetic M is pushed toward the front by the protrusion 6a. At this time, since the applicator body 7 does not move forward, the cosmetic material M pushed toward the front side is smoothly stored in the first concave portion 7e and the second concave portion 7f.

  When the moving body 6 continues to move forward as described above, the protruding portion 6a of the moving body 6 contacts the stepped portion 7c of the coating body 7. In this state, when the operating cylinder 3 is further relatively rotated in one direction to move the moving body 6 forward, the projecting portion 6a is in contact with the step portion 7c, so that the moving body 6 and the applying body 7 also start moving forward. ..

  Then, as shown in FIG. 3, when the moving body 6 and the coating body 7 reach the forward limit, the protrusion 6 a approaches the rear end of the first sealing member 8 and the front end of the protrusion 6 d moves to the first end. The front end of the protruding portion 6d abuts on the step portion 2j while being close to the rear end of the second sealing member 9. Further, the screwing projection 6c of the moving body 6 contacts the projection 5e (side surface 5e3) of the second screw cylinder 5, and the screwing projection 5a of the second screw cylinder 5 is the projection 4e of the first screw cylinder 4. By making contact with the (side surface 4e3), further advancement of the moving body 6 and the second screw cylinder 5 is restricted. Further, the front end of the rear side cylinder portion 4b of the first screw cylinder 4 comes into contact with the rear end of the container body 2, and further advancement of the first screw cylinder 4 is restricted.

  For example, in the female screw portion 3a, the female screw portion 4c, and the female screw portion 5c, the screwing protrusion 6c abuts the protrusion 5e and the screwing protrusion 5a abuts the protrusion 4e in the forward movement limit. The shapes and lengths of the female screw portion 3a, the female screw portion 4c, and the female screw portion 5c are set so that the front end of the rear tubular portion 4b contacts the rear end.

  Further, when the moving body 6 and the coating body 7 are moved forward as described above, the coating portion 7a of the coating body 7 is moved forward and the expanded diameter portion 7g, the first concave portion 7e and the second concave portion 7f are formed in the container body 2. Exposed in front. In this way, the application part 7a of the application body 7 appears from the front end of the applicator 100, so that the user can apply the cosmetic M contained in the first recess 7e and the second recess 7f to the application target. Becomes

  After the user applies the cosmetics M, when the user relatively rotates the operation tube 3 in the other direction (for example, counterclockwise) with respect to the container body 2, the screwing action of the first screwing portion 11, The screwing action of the second screwing portion 12 and the screwing action of the third screwing portion 13 work. Then, the first screw cylinder 4 is retracted by the screwing action of the first screwing portion 11, the second screw cylinder 5 is retracted by the screwing action of the second screwing portion 12, and the third screw cylinder 5 is retracted. The moving body 6 retracts due to the screwing action of the joining portion 13.

  Then, the moving body 6 retreats in the moving region 2e of the container body 2, but at this time, the coating body 7 does not retreat. That is, the relative position of the moving body 6 with respect to the application body 7 is returned to the initial state by retracting the moving body 6 relative to the application body 7. When the moving body 6 retreats with respect to the application body 7 in this manner, the projection 6g of the moving body 6 comes into contact with the annular projection 7d of the application body 7 from the front, and then the application body 7 moves backward together with the moving body 6. To do. Then, as shown in FIG. 1, the application body 7 is retracted into the container body 2 from the front, and the rear end of the moving body 6, the rear end of the second screw cylinder 5, and the rear end of the first screw cylinder 4 are inserted. The use of the applicator 100 is completed by bringing the end into contact with the bottom surface 3b of the operation tube 3 and setting the initial state.

  As described above, in the applicator 100 of the present embodiment, the applicator body 7 and the moving body 6 connected to the applicator body 7 so as to be movable by a certain amount in the axial direction advance, and the applicator body 7 becomes a container. It is pushed out from the front end of the main body 2. The application body 7 has a first concave portion 7e and a second concave portion 7f for accommodating the cosmetic material M on the surface thereof, and the first concave portion 7e and the second concave portion 7f are advanced as the application body 7 advances. It is exposed in front of the container body 2. Therefore, it is possible to expose the first concave portion 7e and the second concave portion 7f in a state where the cosmetic material M is stored in the first concave portion 7e and the second concave portion 7f to make the application body 7 usable.

  Further, the moving body 6 is provided with a protruding portion 6a that pushes the cosmetic material M in the housing portion 2d toward the front side of the housing portion 2d by advancing with respect to the application body 7. In this way, since the cosmetic material M in the housing portion 2d can be concentrated on the front side by the projecting portion 6a that advances with respect to the application body 7, even when the cosmetic material M in the housing portion 2d decreases. Therefore, the cosmetic material M can be stably contained in the first recess 7e and the second recess 7f. Therefore, even if the user continues to use the cosmetic material for a long period of time, the cosmetic material M can be stored in the first concave portion 7e and the second concave portion 7f, so that the discharge amount of the cosmetic material M can be stabilized for a long period of time. ..

  Further, the protruding portion 6a protrudes outward in the radial direction on the front side of the moving body 6, the outer diameter of the protruding portion 6a is smaller than the inner diameter of the housing portion 2d, and the outer diameter of the applying body 7 (the applying portion 7a and the applying portion 7a Larger than the outer diameter of the insertion portion 7b). Therefore, since the outer diameter of the protrusion 6a is smaller than the inner diameter of the accommodation portion 2d, the protrusion 6a can be smoothly advanced. Furthermore, since the cosmetic material M can escape rearward from the gap formed between the protruding portion 6a and the inner surface of the housing portion 2d, it is possible to prevent excessive pressure from being applied to the front side of the housing portion 2d. Therefore, the cosmetic material M can be appropriately concentrated on the front side of the housing portion 2d.

  Further, the applicator 100 includes a tubular container body 2 and an operation tube 3, and the container body 2 and the operation tube 3 are relatively rotatable in one direction. Inside the cylinder 3, there are provided a first screwing portion 11, a second screwing portion 12 and a third screwing portion 13 formed by male and female screws, and the moving body 6 is connected to the container body 2 and When the operating cylinder 3 is relatively rotated in one direction, the male screw and the female screw work together to move forward. That is, the plurality of screwing portions 11, 12, 13 are provided inside the container body 2 and the operation tube 3, and the moving body 6 has the screwing action of the plurality of screwing portions 11, 12, 13 working. To move forward.

  When the plurality of screwed portions 11, 12, and 13 are provided in this way, the moving amount of the moving body 6 during relative rotation can be increased as compared with the case where there is one screwed portion. Further, when the plurality of threaded portions 11, 12, and 13 are provided, it is possible to secure the movement amount of the moving body 6 even if the container body 2 and the operation tube 3 have a short length (length in the axial direction). Therefore, it is possible to shorten the lengths of the container body 2 and the operation tube 3 as compared with the case where one screwing portion is provided.

  Further, the moving body 6 advances with respect to the application body 7 by a predetermined amount, and then advances with the application body 7. Therefore, since the moving body 6 moves relative to the application body 7 before moving forward together with the application body 7, the protrusion 6 a also moves forward relative to the application body 7. Therefore, the cosmetic material M can be moved forward along the application body 7 while the protrusion 6 a is relatively moved forward with respect to the application body 7. Therefore, the cosmetic material M can be easily stored in the first concave portion 7e and the second concave portion 7f on the surface of the application body 7.

  Further, the applicator 7 and the moving body 6 are retracted from the state where the applicator 7 is pushed out from the front end of the container body 2, the applicator 7 is immersed in the container body 2, and the moving body 6 is the applicator. After a certain amount of retreat with respect to 7, it retreats together with the coating body 7. Therefore, since the applicator 7 is retracted into the container body 2 as it is retracted, the applicator 7 can be retracted into the container body 2 at the end of use, for example.

  Therefore, when not in use, it is possible to immerse the applicator body 7 so that the first concave portion 7e and the second concave portion 7f are not exposed, and thus it is possible to prevent the cosmetic material M from hardening. .. Further, first, by moving the moving body 6 backward relative to the coating body 7, it is possible to surely return the position of the protruding portion 6a to the state before use (initial state). Therefore, the cosmetic material M can be reliably pushed forward by the protrusion 6a even when it is used next time.

  Further, the protrusion 6 a contacts the step portion 7 c of the application body 7 when the moving body 6 advances by a certain amount with respect to the application body 7, and the moving body 6 advances by a certain amount with respect to the application body 7. The applicator body 7 is pressed forward by the contact of the projecting portion 6a with the step portion 7c, and moves forward together with the applicator body 7. Therefore, both the function of pushing the cosmetic material M forward and the function of advancing the application body 7 together with the moving body 6 can be made to function as the projecting portion 6a.

  Further, the first sealing member 8 seals the housing portion 2d and handles the cosmetic material M on the outer peripheral surface of the application portion 7a. Since the accommodation portion 2d is sealed by the first sealing member 8, the situation in which the cosmetic material M is hardened is prevented, and the first sealing member 8 handles the cosmetic material M and is discharged. Since it is possible to prevent the cosmetic M from becoming too large, it is possible to discharge an appropriate amount of the cosmetic M.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, but is modified within a range not changing the gist described in each claim or applied to other things. May be That is, the configuration of each component that constitutes the applicator 100 can be appropriately changed without changing the above-mentioned gist.

  For example, in the above-described embodiment, the elongated round bar-shaped application body 7 has been described, but the shape of the application body can be appropriately changed. For example, as shown in FIG. 12 showing the cross section of the application body 17, the container body 2 and the moving body 6 according to the modified example, the cross section of the application body 17 may be an elliptical shape with both ends in the major axis direction being sharp. The applicator body 17 is provided with a pair of pointed heads 17a that taper toward both ends in the major axis direction, and each pointed head 17a is provided with a recessed portion 17e corresponding to the recessed portions 7e and 7f for containing the cosmetic material M. Has been.

  In this modification, the outer diameter of the projecting portion 6a of the moving body 6 is smaller than the inner diameter of the housing portion 2d and larger than the minor diameter (minor axis diameter) of the application body 17. That is, the outer diameter of the protrusion 6 a is larger than the minimum outer diameter of the application body 17. Also in the case of this modification, the protruding portion 6a can be smoothly advanced, and the cosmetic material M can be released rearward from the gap formed between the protruding portion 6a and the inner surface of the housing portion 2d. Therefore, it is possible to prevent excessive pressure from being applied to the front side of the storage section 2d, and the cosmetic material M can be appropriately concentrated on the front side of the storage section 2d.

  Further, in the above-described embodiment, the moving body 6 having an elongated round bar shape has been described, but the shape of the moving body can be changed as appropriate. For example, an outer diameter may be made larger than that of the protruding portion 6a shown in FIG. 1 and the like, and the protruding portion may slide on the inner surface of the housing portion 2d (having the same outer diameter as the inner diameter of the housing portion 2d). Then, a passage for circulating the cosmetic M may be formed in the protruding portion so as to penetrate in the axial direction.

  In this case, since the protrusion has a passage through which the cosmetic M passes from the front side to the rear of the protrusion, the protrusion causes the cosmetic M to move toward the front side while part of the cosmetic M passes through the passage. You can escape from behind. Therefore, it is possible to prevent excessive pressure from being applied to the front side of the protruding portion, and it is possible to appropriately concentrate the cosmetic material M on the front side of the housing portion 2d.

  Further, in the above-described embodiment, an example has been described in which the pressing portion that concentrates the cosmetic material M on the front side of the housing portion 2d is the protruding portion 6a that protrudes radially outward on the front side of the moving body 6. However, the pushing portion may have a shape other than the protruding portion 6a. For example, instead of the protruding portion 6a of the moving body 6, the entire insertion portion 6e of the moving body 6 may be thickened and the front end of the insertion portion 6e may be used as the pushing portion.

  Further, in the above-described embodiment, the example in which the application body 7 includes the first concave portion 7e and the second concave portion 7f in a pair has been described. However, the shape and arrangement of the concave portion for accommodating the cosmetic material M formed on the surface of the application body 7 are not limited to the above-mentioned first concave portion 7e and second concave portion 7f, and can be changed as appropriate. The type and number of recesses formed on the surface of the applicator body 7 can be changed as appropriate.

  Further, in the above-described embodiment, an example has been described in which the applicator body 7 includes the step portion 7c, and the projecting portion 6a is abutted against the step portion 7c so that the applicator body 7 advances together with the moving body 6. However, the predetermined portion of the applicator 7 that comes into contact when the moving body 6 advances by a certain amount with respect to the applicator 7 is not limited to the step portion 7c. For example, in place of the stepped portion 7c, a portion where the stepped portion 7c is provided may be provided with a measure for increasing the friction coefficient, and the portion may be set as the predetermined portion. In this case, the applicator 7 advances together with the moving body 6 by the protrusion 6a coming into contact with the location where the coefficient of friction is increased.

  In addition, in the above-described embodiment, the first screw cylinder 4, the second screw cylinder 5, and the second screw cylinder 5 are screwed by the first screwing portion 11, the second screwing portion 12, and the third screwing portion 13. The example in which the moving body 6 moves forward has been described. However, the number of screwed portions may not be three, and the number of screw cylinders may not be two. That is, the numbers of screwing portions and screw cylinders can be changed as appropriate. Further, instead of the first screwing portion 11, the second screwing portion 12, and the third screwing portion 13, for example, the moving body 6 may be moved forward by a slide mechanism slidable in the axial direction. That is, it is possible to move the moving body 6 forward by using a mechanism other than the screwing portion.

  Further, in the above-described embodiment, an example has been described in which the moving body 6 advances by the relative rotation of the container body 2 and the operation tube 3 in one direction, and the moving body 6 retracts by the relative rotation of the other direction. However, the moving body 6 may be moved forward or backward by means other than relative rotation, such as the slide mechanism. Further, instead of the two containers of the container body 2 and the operation tube 3, one container or three or more containers may be used.

  Further, in the above-described embodiment, the cosmetic material M is exemplified as the coating material stored in the housing portion 2d. However, as the coating material, it is possible to use a coating material other than the cosmetic material such as ink or stick glue.
