  By the way, in general, in the coating material extrusion container, for example, from the viewpoint of operability and usability, it is desired that the coating material is surely moved into and out of the container during the initial operation. There is a demand for reliably moving the coating material with respect to the front tube. Here, when the coating material moves in the pipe member, it is found that the coating material may be difficult to move depending on the state of the coating material accompanying a temperature change. Therefore, at the time of initial operation, it is preferable to first move the pipe member together with the coating material with respect to the tip tube.

  In this regard, in the above-described coating material extruding container, the order of operation is set depending on the size of the leads in the first and second screwing portions, whereby the movement of the pipe member with respect to the front tube and the coating material with respect to the pipe member are set. The order of movement (hereinafter referred to as “movement order”) is controlled. However, for example, when an abnormality such as an extreme increase in frictional resistance due to a dimensional error or screw clogging occurs in at least one of the first and second screwing portions, the operation order of the first and second screwing portions is increased. There is a possibility that a malfunction occurs, and as a result, a malfunction occurs in which the moving order is reversed.

  Therefore, the present invention provides a coating material extruding container that can suppress the occurrence of malfunctions related to the order of movement of the pipe member and the coating material, and can reliably move the coating material with respect to the front tube during the initial operation. Let it be an issue.

  In order to solve the above-described problems, an application material extrusion container according to the present invention is an application material extrusion container that includes first and second screwing portions in a container and extrudes the application material for use. A front tube having a discharge port at the front end, and a pipe member inserted in the inside of the front tube so as to be slidable in the axial direction and loaded with a coating material therein, and a container front portion and a container rear portion Are rotated relative to each other by the screwing action of the first and second screwing parts, the pipe member moves to the one side in the axial direction together with the coating material, and the container front part and the container rear part further move. When the relative rotation is performed, the movement of the pipe member with respect to the front tube stops, and the coating material moves to one side in the axial direction with respect to the front tube and the pipe member by the screwing action in at least one of the first and second screwing portions. It is characterized by moving.

  In the coating material extruding container according to the present invention, when the container front part and the container rear part are relatively rotated, first, the screwing action of the first and second screwing parts works, and the pipe member is applied to the front tube. It moves to the axial direction one side with the material. Then, the movement of the pipe member is stopped, and then the screwing action of at least one of the first and second screwing portions works, and the coating material moves to the one side in the axial direction with respect to the tip tube and the pipe member. Thus, in the present invention, since the screwing action of the first and second screwing parts works in cooperation during the initial operation, for example, even if an abnormality occurs in the first or second screwing part, It is possible to suppress the occurrence of malfunctions related to the order of movement of the pipe member and the coating material. Therefore, in the initial operation, the pipe member can be reliably moved with respect to the front tube, and as a result, the coating material can be reliably moved with respect to the front tube.

  At this time, when the container front part and the container rear part are relatively rotated, the pipe member moves together with the coating material to one side in the axial direction with respect to the front tube by the screwing action of the first and second screwing parts, The screwing action of the first screwing part is released or stopped, and only by the screwing action of the second screwing part, the coating material continues to move to the one side in the axial direction with respect to the front tube and the pipe member, and the container front When the portion and the container rear portion are further rotated relative to each other, the movement of the pipe member with respect to the tip tube stops, and the coating material is applied to the tip tube and the pipe member in the axial direction only by the screwing action of the second screwing portion. It is preferable to move to the side. In this case, when the container front part and the container rear part continue to rotate relatively, the coating material first moves together with the pipe member by the screwing action of the first and second screwing parts, and then the second It moves further with the pipe member only by the screwing action of the screwing part, and then moves only by the screwing action of the second screwing part within the pipe member.

  At this time, after the movement of the pipe member with respect to the front tube is stopped, the coating material moves to one side in the axial direction with respect to the front tube and the pipe member by the screwing action of the first and second screw portions, and the container front When the portion and the container rear portion are further rotated relative to each other, the screwing action of the first screwing part is released or stopped, and only the screwing action of the second screwing part is applied to the leading tube and the pipe member. It is preferable that the coating material continues to move to one side in the axial direction. In this case, if the container front portion and the container rear portion continue to rotate relative to each other, the coating material first moves together with the pipe member, and then the first and second threaded portions are screwed in the pipe member. Then, it moves further only by the screwing action of the second screwing portion in the pipe member.

  The pipe member is slidably inserted in the axial direction and includes an extruding portion for moving the coating material. The tip tube, the pipe member, and the extruding portion have sliding resistance between the tip tube and the pipe member. It is preferable to be configured to be smaller than the sliding resistance between the extruded portion and the pipe member. In this case, it is possible to suitably set the moving order in which the coating material moves with respect to the leading tube and the pipe member after the pipe member moves with the coating material with respect to the leading tube.

  In addition, as a configuration that preferably exhibits the above-described effects of the present invention, specifically, a movable body that is disposed in the container and moves the coating material and an intermediate portion that engages with the front of the container so as to be able to rotate synchronously. And an operation body that constitutes a rear portion of the container and engages with the movable body so as to be able to rotate synchronously, and the first screwing portion is provided between the intermediate body and the operation body, and the second screw A configuration in which the joint portion is provided between the moving body and the intermediate body is exemplified.

  According to the present invention, it is possible to suppress the occurrence of malfunctions related to the order of movement of the pipe member and the coating material, and to reliably move the coating material with respect to the leading tube during the initial operation.

It is a longitudinal cross-sectional view which shows the state of the piston advance limit in a material extrusion container. As shown in FIG. 1, the coating material extruding container 100 of the present embodiment accommodates the coating material M and can be pushed out and pulled back appropriately by the user's operation.

  Examples of the coating material M include various stick-shaped cosmetics such as lipstick, lip gloss, eyeliner, eye color, eyebrow, lip liner, cheek color, concealer, beauty stick, hair color, and writing tools. It is possible to use a rod-shaped core, etc., and particularly a very soft rod-like material (semi-solid, soft-solid, soft, jelly-like, mousse-like, or a kneaded shape containing these) is used. Is preferred. Further, a thin rod-shaped object having an outer diameter of 1 mm or less or a thick rod-shaped object having a diameter of 10 mm or more can be used.

  The coating material extruding container 100 includes a front tube 1 having a filling region 1x filled with the coating material M and having a discharge port 1a at the tip, and a front half portion of the front tube 1 inserted in the front half thereof. 1 is engaged with the axial direction and the rotational direction around the axial line (hereinafter also simply referred to as “rotational direction”) and is connected so as to be integrated with each other, and the rear end portion of the main body cylinder 2 is relatively rotatable. An operation cylinder 3 connected in the axial direction is provided as an outer configuration, and a front part of the container is constituted by the front cylinder 1 and the main body cylinder 2, and a rear part of the container is constituted by the operation cylinder 3. The “axis” means a center line extending in the front-rear direction of the coating material extruding container 100 (hereinafter the same).

  The coating material extruding container 100 includes a rotation stopper cylinder 4, a moving screw cylinder 5, a moving body 6, and a piston 7 therein. The rotation stop cylinder 4 is rotatable relative to the main body cylinder 2 and engages in the axial direction.

The groove portions 12x and 12y have different groove widths in the circumferential direction. Here, the groove width of the groove portion 12x is larger than the groove width of the groove portion 12y.

  Between the coating material hole 11a and the pipe member hole 11b, a step surface 11c that engages the tip surface of the pipe member 10 in the axial direction is formed to stop the advancement of the pipe member 10. The step surface 11c has a surface shape corresponding to the tip of the pipe member 10, and here is formed by an inclined angle surface inclined at an angle corresponding to the discharge port 1a (the predetermined angle).

  Further, a stepped surface 11d is formed at the central portion in the axial direction of the pipe member hole 11b to ensure the thickness of the pipe member 10 and stabilize the moldability. The step surface 11d is an annular inclined surface that extends in the circumferential direction and is inclined so that the diameter of the rear side is increased with respect to the axial direction. Thereby, in the pipe member hole 11b, the hole diameter on the rear side of the step surface 11d is slightly larger than the hole diameter on the front side of the step surface 11d.

  As shown in FIG. 1, the pipe member 10 has a cylindrical shape, and the opening at the front end thereof is formed by an inclined angle surface that is inclined at the predetermined angle in the same manner as the discharge port 1a. The pipe member 10 includes a filling region 1x therein. Specifically, the pipe member 10 is filled with the coating material M and loaded, and the coating material M is in close contact with the pipe member 10 so as to be slidable in the axial direction. The inner diameter of the pipe member 10 is equal to the inner diameter of the coating material hole 11 a of the front tube 1. Thereby, when the pipe member 10 is accommodated in the pipe member hole 11b of the front tube 1, the inner peripheral surface of the pipe member 10 and the inner peripheral surface of the coating material hole 11a of the front tube 1 are flush with each other. Yes.

  On the other hand, the outer diameter of the pipe member 10 is slightly smaller (for example, 15/100 mm) than the inner diameter of the pipe member hole 11b of the front tube 1. Thereby, when the pipe member 10 is accommodated in the pipe member hole 11b of the front tube 1, a predetermined clearance is formed between the pipe member 10 and the front tube 1 in the radial direction. It is slidable in the axial direction with respect to the front tube 1, and its sliding resistance is a desired sliding resistance according to a predetermined clearance. Here, the pipe member 10 is slidable in the axial direction with respect to the front tube 1 with the first sliding resistance.

  As shown in FIGS. 9 and 10, a step surface 10 a is formed on the outer peripheral surface of the pipe member 10 on the front side in the axial center portion so as to correspond to the step surface 11 d (see FIG. 8) of the pipe member hole 11 b. Has been. The step surface 10a is an annular inclined surface similar to the step surface 11d. That is, the step surface 10a is an annular inclined surface that extends in the circumferential direction and inclines so that the diameter of the rear side of the axial direction increases. Thereby, in the pipe member 10, the outer diameter on the rear side of the step surface 10a is slightly larger than the outer diameter on the front side of the step surface 10a.

  In addition, on the rear side of the axial center portion on the outer peripheral surface of the pipe member 10, a pair of protrusions 10x extending short in the axial direction is assumed to be engaged with the grooves 12x and 12y of the pipe member hole 11b in the rotational direction. , 10y are provided so as to face each other. The ridges 10x and 10y have different circumferential widths. Here, the width of the ridge 10x is larger than the groove width of the ridge 10y.

  As shown in FIGS. 1 and 8 to 10, in the front tube 1, the pipe member 10 is inserted and accommodated in the pipe member hole 11 b, and the pipe member 10 can be slid in the axial direction with respect to the front tube 1. ing. At this time, the protrusion 10x is engaged with the groove portion 12x in the rotation direction, and the protrusion 10y is engaged with the groove portion 12y in the rotation direction, whereby the relative rotation of the pipe member 10 with respect to the front tube 1 is restricted. Yes.

  The front tube 1 configured as described above is inserted between the main body tube 2 and the moving screw tube 5 from the rear side, and the annular concavo-convex portion 2b of the main body tube 2 is engaged with the annular convex recess 1b in the axial direction. At the same time, the knurl 2a of the main body cylinder 2 is engaged with the protrusion 1g in the rotation direction so that the main body cylinder 2 is engaged and mounted in the axial direction and the rotation direction, and is integrated with the main body cylinder 2. .

  Further, the piston 7 is inserted into the rear end portion of the pipe member 10 of the front tube 1 so as to be tightly adhered. That is, the piston 7 is inserted into the pipe member 10 and is located behind the coating material M in the pipe member 10 and is in close contact with the pipe member 10 so as to be airtight. The pipe member 10 is slidable in the axial direction with a second sliding resistance greater than the sliding resistance.

  Further, as shown in FIG. 1, in the coating material extruding container 100, the main body cylinder in the radial direction is between the rear end surface of the front cylinder 1 in the axial direction and the flange 54 (see FIG. 7) of the moving screw cylinder 5. A coil spring 14 is mounted coaxially at a position between the pipe member 10 and the pipe member 10. The coil spring 14 is an elastic member having a predetermined elastic force, and biases the moving screw cylinder 5 rearward in the axial direction. Thereby, when the moving screw cylinder 5 moves forward by a certain amount and the screwing action of the first screwing part 8 is released, the moving screw cylinder 5 is set so that the first screwing part 8 is screwed back. Be energized.

  Incidentally, the screwing return here means a stage in which the protrusion 56 as the male screw of the first screwing portion 8 returns until it comes into contact with the side surface of the screw thread of the protrusion 41 as the female screw. (same as below). As the coil spring 14, for example, a resin spring produced by injection molding of a cylindrical shape with a part cut away using a resin such as POM or PP (polypropylene), or a spring made of stainless steel wire in a coil shape is adopted. Can do.

  Next, an example of operation | movement of the coating material extrusion container 100 is demonstrated.

  For example, in the coating material extruding container 100 in the initial state, the coating material M is in close contact with the coating material hole 11 a of the front tube 1, the inner peripheral surface of the pipe member 10, and the piston 7. The tip end surface of the pipe member 10 is positioned farther to the rear side than the step surface 11 c of the front tube 1, and the pipe member 10 can be advanced relative to the front tube 1.

  In the initial state of the coating material extruding container 100, when the user removes the cap C (see FIG. 1) and the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction which is the feeding direction, the rotation stop cylinder The four convex portions 44 come into contact with the convex portion 36 of the operation cylinder 3 and are locked (tightly engaged) in the rotation direction, so that the operation cylinder 3 and the rotation stopper cylinder 4 are rotated synchronously. As a result, the movable screw cylinder 5, the operation cylinder 3, and the rotation stopper cylinder 4 rotate relative to each other, and the first screwing portion 8 constituted by the protrusion 56 of the movement screw cylinder 5 and the protrusion 41 of the rotation stopper cylinder 4. The moving screw cylinder 5 moves forward by the cooperation of the rotation stop portion formed by the protrusion 55 of the moving screw cylinder 5 and the protrusion 1g of the leading cylinder 1. The body 6 moves forward.

  At the same time, the leading cylinder 1 and the moving screw cylinder 5 and the moving body 6 rotate relative to each other, and the second screwing portion 9 constituted by the female screw 53 of the moving screw cylinder 5 and the male screw 6b of the moving body 6 is used. The screwing action works, and the moving body 6 moves forward by the cooperation of the rotation stop portion constituted by the protrusion 37 of the shaft body 31 y and the protrusion 6 c of the moving body 6 in the operation cylinder 3. That is, the moving body 6 moves forward with the moving screw cylinder 5 and simultaneously moves forward with respect to the moving screw cylinder 5.

  As a result, the moving body 6 moves forward by a predetermined amount with respect to the piston 7, the moving body 6 contacts the rear end surface of the piston 7 and presses the piston 7 forward, and the piston 7 moves forward with respect to the front tube 1. The pipe member 10 moves forward integrally with the piston 7 by the sliding resistance between the pipe member 10 and the pipe member 10. Accordingly, as the pipe member 10 advances, the coating material M is also fed out to the front tube 1 (that is, the pipe member 10 is advanced together with the coating material M with respect to the front tube 1), and the coating material M is discharged from the discharge port 1a. Appears from.

  At this time, as described above, since the protrusions 10x and 10y are engaged with the grooves 12x and 12y of the front tube 1 in the rotation direction, the forward movement of the pipe member 10 with respect to the front tube 1 can be guided (guided). The pipe member 10 can be moved straight forward without rotating in the circumferential direction. Therefore, when the pipe member 10 moves, the inclined angle surface at the opening on the distal end side of the pipe member 10 is always in a substantially parallel state with the inclined angle surface of the discharge port 1a.

  Subsequently, when the relative rotation in one direction is continued, the protrusion 56 of the moving screw cylinder 5 comes off from the front end of the protrusion 41 of the rotation stopper cylinder 4, and the screwing action of the first screwing portion 8 is released. The moving screw cylinder 5 reaches the forward limit. Therefore, when the relative rotation in one direction is further continued, only the screwing action of the second screwing part 9 acts while the first screwing part 8 is urged by the coil spring 14 so that the screwing is restored. The pipe member 10 moves slowly together with the coating material M as the piston 7 advances with respect to the cylinder 1. Then, the tip surface of the pipe member 10 engages with the step surface 11c of the front tube 1 in the axial direction, and the advance of the pipe member 10 with respect to the front tube 1 stops (the pipe member 10 reaches the forward limit, see FIG. 1). ).

  Subsequently, when the relative rotation in one direction is continued, only the screwing action of the second screwing part 9 continues to act while the first screwing part 8 is urged by the coil spring 14 so as to return to the screwing. In the stopped pipe member 10, the coating material M is pushed out by the piston 7 and moves forward (that is, the coating material M moves forward with respect to the front tube 1 and the pipe member 10). Thereafter, the moving body 6 and the piston 7 reach the forward limit (see FIG. 2).

  In the state where the moving screw cylinder 5 is in the forward limit, the moving screw cylinder 5 is urged rearward by the elastic force of the reduction of the coil spring 14, so that the main body cylinder 2 and the operation cylinder are moved in the other direction which is the retraction direction. 3 is relatively rotated, the protrusion 56 of the moving screw cylinder 5 immediately enters the tip of the protrusion 41 of the rotation stopper cylinder 4 adjacent to the rotation direction, and the first screwing portion 8 is immediately screwed back. .

  Further, when only the screwing action of the second screwing part 9 works and the piston 7 further moves forward, the first screwing part 8 released from the screwing is attached in the direction in which the screwing is restored by the biasing force of the coil spring 14. Therefore, the engagement and disengagement between the protrusions 41 and 56 are repeated (that is, the protrusions 41 and 56 are repeatedly brought into contact with and separated from each other), and the engagement and engagement are performed. A click feeling is given to the user at each release, and the push of the coating material M is perceived by the user. At this time, as described above, since the protrusion 41 is softer than the protrusion 56 (has flexibility), the click sound (volume) of the generated click feeling is reduced, and the click sound Is considered profound in the bass.

  Incidentally, in the forward limit state of the movable body 6 and the piston 7, the second threaded portion 9 remains screwed although the ridge 6c of the movable body 6 is disengaged from the ridge 37 of the operating cylinder 3. Then, the moving body 6 is pulled backward by the coil spring 14 through the second screwing portion 9 and the moving screw cylinder 5. Therefore, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the other direction in such a forward limit state, the protrusions 6c and 37 are immediately engaged with each other to act as a rotation stop, and the moving body 6 and the piston 7 moves back immediately.

  On the other hand, for example, in the applied material extruding container 100 after use, the rear end surface of the pipe member 10 is located farther forward than the flange portion 54 of the moving screw cylinder 5, and the rear end surface of the flange portion 54 is The pipe member 10 is located in front of the rotation stop cylinder 4 and can be retracted with respect to the front cylinder 1.

  In the coating material extruding container 100 in the used state, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the other direction, a small rotational force is applied to the operation cylinder 3 and the rotation stopper cylinder 4, and the rotation stopper cylinder 4. The side surface 44a (see FIG. 5) of the convex portion 44 contacts the side surface 36a (see FIG. 4) of the convex portion 36 of the operation cylinder 3, and is engaged in the circumferential direction with a predetermined engagement force. 4 and the moving screw cylinder 5, the operation cylinder 3 and the rotation stopper cylinder 4 are rotated relative to each other, and the screwing action of the first screwing portion 8 works to move the moving screw cylinder 5 backward, Accordingly, the moving body 6 moves backward. At the same time, the leading cylinder 1 and the moving screw cylinder 5 and the moving body 6 rotate relative to each other, and the moving action of the second screwing portion 9 works to move the moving body 6 backward. That is, the moving body 6 is retracted along with the moving screw cylinder 5 and at the same time is retracted independently of the moving screw cylinder 5.

  As a result, the movable body 6 moves backward by a predetermined amount with respect to the piston 7, the tip of the movable body 6 engages with the piston 7 annular protrusion 7 b and pulls the piston 7 backward, and the piston 7 moves backward with respect to the front tube 1. At the same time, the pipe member 10 is retracted integrally with the piston 7 due to the sliding resistance between the piston 7 and the pipe member 10. Accordingly, as the pipe member 10 is retracted, the coating material M is also fed back with respect to the front tube 1 (that is, the pipe member 10 is retracted together with the coating material M with respect to the front tube 1), and the coating material M is discharged from the outlet. Immerse from 1a. At this time, as described above, since the protrusions 10x and 10y are engaged with the grooves 12x and 12y of the front tube 1 in the rotation direction, the pipe member 10 is moved back straight without being rotated in the circumferential direction. Can do.

  Subsequently, when the relative rotation in the other direction is continued, the flange portion 54 of the moving screw cylinder 5 comes into contact with the front end surface of the rotation stopper cylinder 4, and the screwing action of the first screwing portion 8 is stopped, so that the moving screw The cylinder 5 reaches the backward limit. Then, the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the other direction with an operation rotational force larger than that before the stop of the screwing action in the first screwing portion 8, and a large rotational force is applied to the operation cylinder 3 and the rotation stop cylinder 4. Is applied, the convex portion 44 slides over the side surface 36a of the convex portion 36, gets over the convex portion 36, and the operation cylinder 3 and the rotation stop cylinder 4 are relatively rotated (so-called “idle rotation”). . As a result, only the screwing action of the second screwing portion 9 acts, and the pipe member 10 slowly moves back together with the coating material M as the piston 7 moves backward with respect to the front tube 1. The rear end surface of the pipe member 10 abuts on the flange portion 55 in the axial direction. Thereby, the retreat of the pipe member 10 with respect to the front tube 1 stops (the pipe member 10 reaches the retreat limit, see FIG. 3).

  Subsequently, when the relative rotation in the other direction is continued, only the screwing action of the second screwing portion 9 continues to act, the piston 7 moves backward with respect to the stopped pipe member 10, and The application material M is pulled back in the front tube 1 by the pressure reducing action (the action of keeping the sealed state) and retreats (that is, the coating material M moves back with respect to the front tube 1 and the pipe member 10). Thereafter, the rear end of the movable body 6 reaches the bottom surface of the main body 31 of the operation cylinder 3, and the movable body 6 and the piston 7 reach the backward limit.

  By the way, when the projecting portion 44 of the rotation stop cylinder 4 gets over the projecting portion 36 of the operation cylinder 3 when the moving body 6 is further retracted only by the screwing action of the second screwing section 9, a click feeling is generated. That is, when the moving body 6 is further retracted, engagement and disengagement (engagement and disengagement) of the convex portions 44 and 36 are repeated, and the user feels a click each time such engagement and disengagement occurs. Is granted. Thereby, a click feeling of 8 times per one rotation of the relative rotation is generated, and the backward movement of the piston 7 and the moving body 6 is detected. At this time, as described above, since the convex portion 44 is softer than the convex portion 44 (has flexibility), the click sound of the generated click feeling is reduced and the click sound is in the low frequency range. It is supposed to be profound.

  Further, in the state where the movable body 6 and the piston 7 are in the retreat limit, even if excessive rotation force is applied to the second screwing portion 9 after that due to relative rotation in the other direction, the front end is caused by the slit 51 (see FIG. 7). The part 5x is expanded and the screwing action of the second screwing part 9 is released.

  As described above, in the coating material extruding container 100 according to the present embodiment, the first and second screwing portions 8 and 8 are in the initial stage from the start of feeding or the beginning of feeding (during initial operation) until the movement of the pipe member 10 is stopped. For example, even if an abnormality occurs in the first or second screwing portions 8 and 9, a malfunction occurs in the order of movement of the pipe member 10 and the coating material M. Can be suppressed. Therefore, at the time of the initial operation, the pipe member 10 having a large contact area with the coating material M can be reliably moved with respect to the front tube 1, and as a result, the coating material M is brought along with the pipe member 10 to be constant The amount is surely moved.

  By the way, in a general coating material extruding container, for example, when the coating material M contracts due to a low temperature state due to a rapid temperature change and the air is mixed between the pipe member 10 and the coating material M, there is the following possibility. . That is, even if the piston 7 is moved forward, due to the compressibility of the air, there is a possibility that the coating material M may not be pushed out accurately due to the appearance delay (time lag) of the coating material M, or the piston 7 is moved backward. Even if it makes it, it may become difficult for the coating material M to be pulled back (retracted) by the suction action. In this regard, in this embodiment, as described above, since the pipe member 10 itself moves reliably during the initial operation, there is less concern about such a possibility, and the coating material M can be reliably moved.

  Therefore, according to the present embodiment, it is possible to suppress the occurrence of malfunctions related to the order of movement of the pipe member 10 and the coating material M, and to reliably move the coating material M with respect to the front tube 1 during the initial operation. . As a result, the coating material M can surely appear and disappear from the discharge port 1a during the initial operation, and as a result, the operability and usability of the coating material extrusion container 100 can be improved.

  In the present embodiment, as described above, a predetermined clearance is formed between the pipe member 10 and the front tube 1 in the radial direction, and the pipe member 10 can slide on the front tube 1 with the first sliding resistance. It is said that. On the other hand, the piston 7 is in close contact with the pipe member 10 so that the piston 7 can slide with respect to the pipe member 10 with a second sliding resistance larger than the first sliding resistance. Thus, by appropriately adjusting the sliding resistance between the front tube 1, the pipe member 10 and the piston 7, the pipe member 10 and the coating material M move in the order described above, that is, the pipe member 10 is applied to the front tube 1. It is possible to suitably realize that the coating material M moves with respect to the front tube 1 and the pipe member 10 after moving together with M.

  Moreover, in this embodiment, since each of the protrusions 10x and 10y of the pipe member 10 is engaged with each of the groove portions 12x and 12y of the front tube 1 in the rotation direction as described above, When the pipe member 10 is moved, the pipe member can be prevented from rotating with respect to the front tube.

  In the present embodiment, as described above, the circumferential width of the groove 12x and the circumferential width of the groove 12y are different from each other. Since the circumferential width of 10y is different from each other, when the pipe member 10 is assembled to the front tube 1, the position of the pipe member 10 in the rotational direction is restricted (that is, the vertical direction is not reversed). It is possible to prevent erroneous assembly. As a result, the inclined angle surface at the opening on the distal end side of the pipe member 10 and the inclined angle surface of the discharge port 1a can be reliably made substantially parallel.

  In the present embodiment, as described above, the pipe member 10 is moved relative to the front tube 1 by rotating the main body tube 2 and the operation tube 3 in one direction, whereby the first and second screwing portions 8 are engaged. , 9 can be quickly advanced only by the screwing action of the second screwing part 9. Further, by rotating relatively in the other direction, the pipe member 10 is quickly retracted by the screwing action of the first and second screwing portions 8 and 9 with respect to the front tube 1, and then the second screwing portion. 9 can be moved backward slowly only by the screwing action.

  In normal use in the coating material extruding container 100, it is not necessary to rewind the coating material M beyond the retreat limit of the pipe member 10. Therefore, the coating material M is used to be retreated by the retreat of the pipe member 10. There are more. Therefore, in the coating material extruding container 100, even if the coating material M contracts due to temperature conditions and the like and the adhesion to the pipe member 10 and thus the pressure reducing action is reduced, the coating material M is reliably retracted. .

  Incidentally, in this embodiment, the following effects are also exhibited. That is, as described above, when the moving body 6 moves forward or backward only by the second screwing portion 9, a click feeling is given to the user. At the same time, since the protrusion 41 is softer than the protrusion 56, the click sound can be made heavy while reducing (relaxing) the click sound of the click feeling. Therefore, it is possible to make the click sound high-value-added and high-value-added, and to produce a high-quality click feeling.

  As described above, in the above description, the piston 7 constitutes an extrusion portion, the moving screw cylinder 5 constitutes an intermediate body, and the operation cylinder 3 and the rotation stopper cylinder 4 constitute an operation body.

  The preferred embodiment of the present invention has been described above, but the coating material extrusion container according to the present invention is not limited to the above-described embodiment, and is modified without changing the gist described in each claim, or It may be applied to other things.

  For example, in the above embodiment, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated, the pipe member 10 is applied to the front cylinder 1 by the screwing action of the first and second screwing portions 8 and 9. M is moved with M, the screwing action of the first screwing part 8 is released or stopped, and the pipe member 10 is continuously moved together with the coating material M only by the screwing action of the second screwing part 9, and the pipe The forward movement of the member 10 is stopped, and then the coating material M is moved relative to the pipe member 10 only by the screwing action of the second screwing part 9. The release timing or stop timing is not limited to this.

  Specifically, after the pipe member 10 moves together with the coating material M with respect to the front tube 1 by the screwing action of the first and second screwing portions 8 and 9, the movement of the pipe member 10 is stopped, and then The application material M may advance with respect to the pipe member 10 only by the screwing action of the second screwing part 9 when the screwing action of the first screwing part 8 is released or stopped.

  In the above, “releasing the screwing action” means that the threads of the male screw and the female screw (projections 41, 56) are disengaged, and the screwing action does not work. The “stop of the screwing action” means that the screw threads (the protrusions 41 and 56) of the male screw and the female screw are engaged and engaged with each other, and the screwing does not work. In addition, the male screw and female screw described above are not limited to a screw thread and a screw groove, but a thread group and a screw groove, such as an intermittently arranged protrusion group, or a spiral and intermittently arranged protrusion group. It may be one that performs a similar function.

  Further, as the coating material M, for example, lip gloss, lip, eye color, eyeliner, cosmetic liquid, cleaning liquid, nail enamel, nail care solution, nail remover, mascara, anti-aging, hair color, hair cosmetics, oral care, For coating material extrusion containers using liquid coating materials such as massage oil, ink for liquids such as square plug loosening liquid, foundation, concealer, skin cream, marking pens, writing instruments, etc. However, it is of course applicable.
