JP 2008-43590 A

  Here, in the coating material extruding container as described above, when the screwing action of the first screwing part is released, the first screwing part is biased by a spring so as to return to screwing. However, in this case, for example, depending on the dimensional accuracy of the first screwed portion and the spring, the strength of the spring biasing force, or the decrease of the spring biasing force due to the change over time or temperature change, the screwing return of the first screwed portion is achieved. At this time, the male screw and the female screw are difficult to engage with each other, and it may be difficult to return the screwing action.

  Then, this invention makes it a subject to provide the coating material extrusion container which can return the screwing effect | action of a 1st screwing part reliably while preventing the failure | damage of a 1st screwing part.

In order to solve the above-described problem, the coating material extrusion container according to the present invention includes a first screwing portion and a second screwing portion in the container, and the container front portion and the container rear portion are relatively rotated in one direction. Then, the screwing action of the first screwing part works, the moving body moves forward by a certain amount, the screwing action of the first screwing part is released, and when the relative rotation is further performed in one direction, Only the screwing action of the screwing part works, the moving body moves forward, the coating material is pushed out from the opening at the tip of the container, and the container front part and the container rear part are relatively rotated in the other direction which is the opposite direction of one direction. Then, the screwing action of the first screwing part works, the moving body moves backward by a certain amount, the screwing action of the first screwing part is stopped, and the first screwing part is further rotated in the other direction. be those meshing operation of the engaging portion is mobile works only the meshing operation of the second engagement portion in a state of being stopped is retracted, the container front and relative rotation allowed into the container And an operation cylinder that engages the movable body so as to be axially movable and synchronously rotatable. The operation cylinder and the rotation stopper cylinder are synchronously rotated with a rotational force smaller than a predetermined rotational force. Then, the first screwing portion is operated, and the second screwing portion is operated by relative rotation with a rotational force equal to or greater than a predetermined rotational force. It has an elastic force in the direction and has a convex portion that engages with the other of the operation cylinder or the rotation stopper cylinder .

Moreover, the coating material extruding container according to the present invention includes a first screwing portion and a second screwing portion in the container,
When the container front part and the container rear part are relatively rotated in one direction, the screwing action of the first screwing part works, the moving body moves forward by a certain amount, and the screwing action of the first screwing part is stopped. When the relative rotation is further performed in one direction, only the screwing action of the second screwing part works and the moving body advances while the screwing action of the first screwing part is stopped, and the opening of the container tip is opened. When the coating material is pushed out from the container and the container front part and the container rear part are relatively rotated in the other direction, which is the opposite direction of one direction, the screwing action of the first screwing part works and the moving body moves backward by a certain amount. When the screwing action of the first screwing part is released and further relative rotation is performed in the other direction, only the screwing action of the second screwing part works and the moving body moves backward , And an operation cylinder engaged with the movable body so as to be axially movable and synchronously rotatable. The operation cylinder and the rotation stop cylinder rotate synchronously with a rotational force smaller than a predetermined rotational force to operate the first screwing portion, and rotate relative to each other with a rotational force equal to or greater than the predetermined rotational force to rotate the second screw. The joint portion is operated, and is provided on either the operation cylinder or the rotation stopper cylinder, and has a convex portion that has an elastic force in the radial direction and engages the other of the operation cylinder or the rotation stopper cylinder. .

Moreover, the coating material extruding container according to the present invention includes a first screwing portion and a second screwing portion in the container, and when the container front portion and the container rear portion are relatively rotated in one direction, When the moving body moves forward by a certain amount and the screwing action of the first screwing part is stopped and further rotated further in one direction, the screwing of the first screwing part is performed. In the state where the combined action is stopped, only the screwing action of the second screwing part works, the moving body advances, the coating material is pushed out from the opening at the tip of the container, and the container front part and the container rear part are opposite in one direction. When the relative rotation is performed in the other direction, which is the direction, the screwing action of the first screwing part works, the moving body moves backward by a certain amount, the screwing action of the first screwing part is stopped, and further in the other direction. When relative rotation, there is the second only the meshing operation of the engagement portion acts mobile in a state in which the meshing operation of the first engagement portion is stopped is retracted, into the container A rotating cylinder that can rotate relative to the front of the container, and an operating cylinder that engages the movable body so as to be axially movable and synchronously rotatable. The operating cylinder and the rotating cylinder are provided with a predetermined rotational force. In addition, the first screwing part is operated by synchronous rotation with a small rotational force, and the second screwing part is operated by relative rotation with a rotational force equal to or greater than a predetermined rotational force. It has a convex part which is provided in either of these and has an elastic force in the radial direction and engages with the other of the operation cylinder or the rotation stopper cylinder .

  Note that “stopping the screwing action” means that the screw threads of the male screw and the female screw are engaged and engaged with each other, and the screwing does not work. Further, “releasing the screwing action” means that the male screw, the female screw, and the screw thread are disengaged, and the screwing action does not work.

  In the coating material extruding container of the present invention, even if the container front portion and the container rear portion are further rotated relative to each other in a state where the screwing action of the first screwing portion is stopped, excessive rotational force is applied to the first screwing portion. Since the moving body is moved without adding, it is possible to prevent the first screwing portion from being damaged. Further, when the rotation direction of the relative rotation is changed, the screwing action of the stopped first screwing part returns (acts again) without relying on a biasing means such as a spring, so that the screwing of the first screwing part is performed. The combined action can be reliably restored.

It is preferable that they can be rotated synchronously with a force, and can be relatively rotated with a rotational force equal to or greater than a predetermined rotational force. In the present invention, when the container front portion and the container rear portion are relatively rotated and a rotational force smaller than a predetermined rotational force is applied to the operation cylinder and the rotation stopper cylinder, the operation cylinder and the rotation stopper cylinder rotate synchronously. Therefore, for example, when the moving screw cylinder rotates synchronously with the front part of the container, the moving screw cylinder and the moving body, the operation cylinder, and the rotation stopper cylinder rotate relative to each other, so that the first and second screwing portions are screwed together. Will work. When the screwing action of the first screwing portion is stopped, the container front portion and the container rear portion are further rotated relative to each other, and when a rotational force greater than a predetermined rotational force is applied to the operation tube and the rotation stop tube, The cylinder and the rotation stop cylinder rotate relative to each other. Therefore, for example, when the moving screw cylinder rotates synchronously with the front part of the container, the moving screw cylinder and the rotation stop cylinder, the moving body and the operation cylinder rotate relative to each other, so that only the screwing action of the second screwing portion works. It will be.

  Also provided in either one of the operation cylinder or the rotation stopper cylinder, provided with a convex portion having elastic force in the radial direction, and provided in the other of the operation cylinder or rotation stopper cylinder so as to have a sawtooth shape in the circumferential direction. And an engaging force that engages in the rotational direction for the relative rotation between the operation cylinder and the rotation stopper cylinder is an elastic force of the convex part And the shape of the protrusion. In this case, by appropriately setting the elastic force of the convex portion and the shape of the protrusion, the relative rotation between the operation tube and the rotation stop tube can be controlled as desired.

  According to the present invention, it is possible to prevent the first screwing portion from being damaged and to reliably return the screwing action of the first screwing portion.

  That is, first, when the cap 13 is removed by the user and the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction which is the feeding direction, the convex portion 44 of the arm portion 43 of the rotation stop cylinder 4 is moved to the operation cylinder. Since the operation cylinder 3 and the rotation stop cylinder 4 rotate synchronously with the side surface 36b (see FIG. 7) of the projection 36 of FIG. The operation cylinder 3 and the rotation stop cylinder 4 are rotated relative to each other, and the screwing action of the first screwing portion 8 constituted by the protrusion 56 of the moving screw cylinder 5 and the protrusion 41 of the rotation stop cylinder 4 works and moves. The movable screw cylinder 5 moves forward by the cooperation of the rotation stop portion constituted by the protrusion 55 of the screw cylinder 5 and the knurl 1g of the filling member 1. Hereinafter, the predetermined engagement force between the protrusion 44 and the protrusion 36 at the time of relative rotation in one direction is referred to as “one-way engagement force”.

  At the same time, the filling member 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 also moves forward by the cooperation of the rotation preventing 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. In other words, the moving body 6 advances along with the moving screw cylinder 5 and simultaneously advances alone.

  Then, as shown in FIG. 2, when the relative rotation in one direction is continued and the moving screw cylinder 5 moves forward by a certain amount, the front end portion 5x of the moving screw cylinder 5 (located in the enlarged diameter portion 12 of the filling member 1). 1) is located in the inner peripheral surface 11 of the filling member 1. Thereby, the outer diameter of the front end part 5x is regulated by the inner peripheral surface 11 of the filling member 1 so that the front end part 5x does not expand.

  Further, when the relative rotation in one direction is continued, the moving body 6 moves forward, and the protrusion 56 of the moving screw cylinder 5 is disengaged from the front end of the protrusion 41 of the rotation stopper cylinder 4, and the first screwing portion 8 is screwed. The combined action is released, and the moving screw cylinder 5 reaches the forward limit. In the forward limit state of the moving screw cylinder 5, since the moving screw cylinder 5 is urged rearward by the elastic force of the coil spring 14 being reduced, the main body cylinder 2 and the operating 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. It will be.

  Thereafter, when the relative rotation in one direction is further continued, only the screwing action of the second screwing part 9 works while the first screwing part 8 is urged by the coil spring 14 so as to return to the screwing. The body 6 advances further. And as shown in FIG. 3, the protrusion 6c of the moving body 6 remove | deviates from the front-end | tip of the protrusion 37 of the shaft 31y in the operation cylinder 3, a rotation stop part does not work, and the moving body 6 reaches a forward limit.

  In the forward limit state of the moving body 6, the second threaded portion 9 remains screwed although the protrusion 6 c of the moving body 6 is disengaged from the protrusion 37 of the operating cylinder 3. The moving body 6 is pulled backward by the coil spring 14 via the two screwing portions 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 the forward limit state, the protrusions 6c and 37 are immediately engaged with each other, and the rotation stop portion works, so that the moving body 6 is It will immediately retreat.

  On the other hand, for example, after use, 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 arm portion 43 of the rotation stopper cylinder 4 The convex portion 44 is engaged with the side surface 36a (see FIG. 7) of the projection 36 of the operation tube 3 in the circumferential direction with a predetermined engagement force, and the operation tube 3 and the rotation stop tube 4 rotate synchronously. The operation cylinder 3 and the rotation stop cylinder 4 rotate relative to each other, and the screwing action of the first screwing portion 8 works to move the moving screw cylinder 5 backward. Hereinafter, the predetermined engagement force between the projection 44 and the protrusion 36 at the time of relative rotation in the other direction is referred to as “other direction engagement force”.

  At the same time, the filling member 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. In other words, the moving body 6 is retracted along with the moving screw cylinder 5 and is also retracted alone.

  Then, when the relative rotation in the other direction is continued and the moving screw cylinder 5 is retracted by a certain amount, the front end portion 5x of the moving screw cylinder 5 located in the inner peripheral surface 11 of the filling member 1 is expanded. Thus, the restriction of the outer diameter of the front end portion 5x is released, and the front end portion 5x can be expanded.

  Further, 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. The moving screw cylinder 5 and the rotation stopper cylinder 4 can be rotated synchronously by the axial force of the screwing portion 8, and the moving screw cylinder 5 reaches the retreat limit (see FIG. 1). As described above, when the screwing action of the first screwing portion 8 is stopped and the moving screw cylinder 5 and the rotation stopper cylinder 4 can be rotated synchronously, thereafter, the operation cylinder 3 and the rotation stopper cylinder 4 are rotated slightly. Even if force is applied, they are not rotated relative to each other. Therefore, after the screwing action of the first screwing portion 8 is stopped, the main body cylinder 2 and the operation cylinder 3 are moved in the other direction by the same operation rotational force as before the stop (meaning the rotational force by the user; hereinafter the same). Even if relative rotation is attempted, the main body cylinder 2 and the operation cylinder 3 are not relatively rotated.

  However, although the screwing action of the first screwing portion 8 is stopped, the user applies a larger operating torque than before the stop without stopping the relative rotation between the main body cylinder 2 and the operating cylinder 3. When the main body cylinder 2 and the operation cylinder 3 are further relatively rotated in the other direction and a large rotational force is applied to the operation cylinder 3 and the rotation stopper cylinder 4, the operation cylinder 3 and the rotation stopper cylinder 4 are caused by the engagement force in the other direction. Therefore, the projection 44 of the arm 43 slides so as to run up the side surface 36a of the projection 36 and over the projection 36, so that the operation cylinder 3 and the rotation stop cylinder 4 are rotated relative to each other ( Hereinafter, it is also referred to as “idle rotation”. Therefore, the filling member 1, the moving screw cylinder 5 and the rotation stopper cylinder 4, the moving body 6 and the operation cylinder 3 rotate relative to each other, and the screwing action of the first screwing portion 8 is stopped. Only the screwing action of the screwing portion 9 works, and the moving body 6 further moves backward.

  Then, when the relative rotation in the other direction is continued by the operation rotational force larger than that before the stop, 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 reaches the backward limit. In the retreat limit state of the moving body 6, since the restriction of the outer diameter at the front end portion 5 x of the moving screw cylinder 5 is released as described above, the relative rotation in the other direction after that causes excessive rotational force. Even if it joins to the 2nd screwing part 9, the front-end part 5x is expanded and the screwing action of the 2nd screwing part 9 is cancelled | released.

  Note that, for example, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction at the time of an abnormality such as when the first screwing portion 8 is deformed and does not operate, the rotation stop cylinder 4 and the operation cylinder 3 are rotated. A rotational force larger than the one-way engagement force is applied to the arm portion 43, the engagement between the convex portion 44 of the arm portion 43 and the rotation stopper cylinder 4 is released, and the operation cylinder 3 and the rotation stopper cylinder 4 are idled. The filling member 1, the moving screw cylinder 5 and the rotation stopper cylinder 4, the moving body 6 and the operation cylinder 3 rotate relative to each other, and only the screwing action of the second screwing portion 9 works to move the moving body 6 forward. Therefore, since the screwing action of the second screwing portion 9 works and the moving body 6 can move back and forth even during an abnormality, the coating material M can be pushed out and pulled back, and the coating material extrusion container 100 can be used preferably. it can.

  As described above, in the coating material extruding container 100 of the present embodiment, even if the main body cylinder 2 and the operation cylinder 3 are further rotated relative to each other in a state where the screwing action of the first screwing portion 8 is stopped, the operation cylinder 3 and the rotation stop cylinder 4 are idled so that only the screwing action of the second screwing portion 9 works, and the movable body 6 is retracted without applying excessive rotational force to the first screwing portion 8. Therefore, it is possible to prevent the first screwing portion 8 and its peripheral parts from being damaged.

  Further, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction with the screwing action of the screwing part 8 stopped, the screwing action of the first screwing part 8 is attached to a spring or the like. Since it returns immediately (re-acts) without relying on the biasing means, adverse effects caused by the biasing means such as the strength of the biasing means and changes over time can be suppressed, and the screwing of the first screwing portion 8 can be suppressed. The combined action can be reliably restored. That is, according to the present embodiment, the first screwing portion 8 can be prevented from being damaged and the screwing action of the first screwing portion 8 can be reliably restored.

  Further, in the present embodiment, as described above, the convex portion 44 of the arm portion 43 of the rotation stop cylinder 4 and the projection 36 of the operation cylinder 3 are engaged with each other with a predetermined engagement force in the rotation direction. When the operation cylinder 3 is relatively rotated and a rotational force is applied to the operation cylinder 3 and the rotation stop cylinder 4, the operation cylinder 3 and the rotation stop cylinder 4 are rotated relative to each other by the magnitude of the rotation force and the predetermined engagement force. . Therefore, the relative rotation between the operation cylinder 3 and the rotation stopper cylinder 4 can be controlled as desired by appropriately setting the elastic force and the shape of the protrusions of the convex portion 44 of the arm portion 43 and controlling the predetermined engagement force. it can.

  In the present embodiment, as described above, the front end portion 5x provided with the female screw 53 of the second screwing portion 9 in the moving screw cylinder 5 can be expanded radially outward by the slit 51. Yes. Therefore, for example, when the female screw 53 of the moving screw cylinder 5 is formed of a core pin, the core pin can be pulled out in the axial direction (so-called forcible removal) without turning it out. For example, when the moving body 6 is assembled to the moving screw cylinder 5, it is not necessary to rotate the moving body 6 around the moving screw cylinder 5 for the second screwing portion 9, and the moving body 6 is moved to the moving screw cylinder 5. 5 can be inserted and assembled at once in the axial direction. Therefore, manufacture of the coating material extruding container 100 can be facilitated.

  In the present embodiment, as described above, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction and the moving screw cylinder 5 moves forward by a certain amount, the outer diameter of the front end portion 5x of the moving screw cylinder 5 is reduced. Regulated and prevented from spreading. Therefore, when the movable body 6 is further rotated in one direction and the moving body 6 is advanced by the screwing action of the second screwing portion 9, for example, due to the sliding resistance between the coating material M and the inner peripheral surface 11 of the filling member 1. It is possible to prevent the front end portion 5x of the moving screw cylinder 5 from expanding and the inner diameter of the female screw 53 from expanding. That is, when the moving body 6 moves forward, the screwing action of the second screwing portion 9 can be reliably exerted, and the coating material M can be pushed out with sufficient extrusion strength.

  In the present embodiment, as described above, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the other direction, the moving screw cylinder 5 is retracted by a certain amount by the screwing action of the first screwing portion 8. The restriction of the outer diameter at the front end portion 5x of the moving screw cylinder 5 is released. Therefore, even when the moving body 6 is positioned at the retreat limit, the front end portion 5x is expanded and the second screwing is performed even if the relative rotation is further performed in the other direction and an excessive rotational force is applied to the second screwing portion 9. Since the screwing action of the portion 9 is released, the second screwing portion 9 and its peripheral parts can be prevented from being damaged.

  In the present embodiment, as described above, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction and the moving screw cylinder 5 reaches the forward limit, the screw threads of the first screwing portion 8 are connected to each other. Although it is disengaged and does not mesh, since the biasing force of the coil spring 14 biases it in the direction of screwing return, the relative rotation in one direction is continued as it is, and the moving body 6 advances only with the second screwing portion 9. When this is done, a click feeling is generated, so that the extrusion of the coating material M can be detected.

  In the present embodiment, as described above, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the other direction and the moving screw cylinder 5 reaches the retreat limit, the screwing action of the first screwing portion 8 is performed. When the rotation is stopped and the relative rotation in the other direction is further continued, the convex portion 44 of the arm portion 43 of the rotation stopper cylinder 4 gets over the protrusion 36 of the operation cylinder 3, and the rotation stopper cylinder 4 and the operation cylinder 3 rotate relative to each other. When the convex portion 44 gets over the protrusion 36, a click feeling is generated, so that the backward movement of the piston 7 and the moving body 6 can be detected.

  Moreover, in this embodiment, since the lead of the 1st screwing part 8 is set larger than the lead of the 2nd screwing part 9, as mentioned above, there exists the following effect. That is, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction, the coating material M is quickly pushed out until it is used, and then slowly pushed out. . Further, when the coating material M is relatively rotated in the other direction, the coating material M retracts quickly by a certain amount and then slowly retracts, so that the coating material M can be prevented from returning too much.

  In addition, the charging material M can be charged into the filling member 1 by filling the molten coating material M from the front end side of the filling member 1 or filling the coating material M from the rear end side of the filling member 1. 1 can be assembled. Further, when the coating material M is a rod-shaped article formed by a mold or extrusion molding, the coating material M can be loaded after assembly.

  Further, by adopting the rotation stop cylinder 4 as in the present embodiment, a certain amount of advance (or retreat) of the moving body 6 and the moving screw cylinder 5 by the first screwing portion 8 is about 1-2 mm. It is also possible to set the lead to a very small amount. And in advance (or retreat) only by the second screwing part 9 after a certain amount of advance (or retreat), the moving body 6 can be slowly advanced (or retreated) with a lead of about 0.5 mm, Even if the coating material M is very soft, the coating material M can be used without breaking down.

  Incidentally, in this embodiment, when the main body cylinder 2 and the rotation stop cylinder 4 are rotated relative to each other, the moving screw cylinder 5 moves forward / backward by a fixed amount by the screwing action of the first screwing portion 8. If the cylinder 5 can be moved forward by a certain amount, various means may be employed instead of the first screwing portion 8, and for example, a ratchet mechanism as shown in FIG. 14 may be employed.

  In another example of the rotation stopper cylinder 4 and the moving screw cylinder 5 shown in FIG. 14, the rotation stopper cylinder 4 is configured to have a convex portion 48 instead of the female screw 41 of the first screwing portion 8. The moving screw cylinder 5 is configured to have a convex portion 58 instead of the male screw 56 of the screwing portion 8. The convex portion 48 is provided side by side along the circumferential direction on the end face 47 on the front end side of the rotation stopper cylinder 4 and has a mountain shape inclined toward one side in the circumferential direction. The convex portion 58 is provided side by side along the circumferential direction at the end surface 57 on the rear end side of the moving screw cylinder 5 and has a mountain shape inclined toward the other side in the circumferential direction. The rotation stopper cylinder 4 and the moving screw cylinder 5 are mounted so that the inclined surfaces 49 and 59 of the convex portions 48 and 58 are in contact with each other, and when they are relatively rotated in one direction, the inclined surface 49 59, the moving screw cylinder 5 moves forward, and when it is relatively rotated in the other direction, the moving screw cylinder 5 moves backward by a predetermined amount by the biasing forces of the inclined surfaces 49, 59 and the coil spring 14.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.

  For example, in the above embodiment, the protrusion 56 as the male screw of the first screwing portion 8 is provided on the outer peripheral surface of the moving screw cylinder 5, and the protrusion 41 as the female screw is provided on the inner peripheral surface of the rotation stopper cylinder 4. Although provided, the male screw of the first screwing portion 8 may be provided on the inner peripheral surface of the moving screw cylinder 5, and the female screw may be provided on the outer peripheral surface of the rotation stop cylinder 4.

  In the above embodiment, the screwing action of the first screwing part 8 is released after the moving screw cylinder 5 has moved forward by a certain amount by the screwing action of the first screwing part 8. The screwing action of the screwing part 8 may be stopped. In this case, when the relative rotation is further performed in one direction, only the screwing action of the second screwing part 9 works and the moving body 6 advances while the screwing action of the first screwing part 8 is stopped. . Further, in this case, after the moving screw cylinder 5 is retracted by a certain amount due to the screwing action of the first screwing part 8, the screwing action of the first screwing part 8 is released and further rotated in the other direction. Then, only the screwing action of the first screwing part 9 works and the moving body 6 may be retracted.

  In addition, by setting the height and shape of the protrusion 36 so that the one-way engagement force becomes extremely large, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction, the operation cylinder 3 and the rotation stop cylinder 4 The relative rotation may be substantially impossible.

  Further, in the above embodiment, the convex portion 44 is provided on the rotation stopper cylinder 4 and the projection 36 that engages with the convex portion 44 is provided on the operation cylinder 3, but the convex portion 44 is provided on the operation cylinder 3. The rotation stopper cylinder 4 may be provided with a protrusion 36 that engages with the convex portion 44.

  Moreover, in the said embodiment, since the internal diameter of the internal peripheral surface 11 of the filling member 1 is slightly larger than the outer diameter of the front-end part 5x of the moving screw cylinder 5, the outer diameter of the front-end part 5x is controlled by non-contact. However, it may be regulated by making it contact so as to slide.

  Moreover, in the said embodiment, although the enlarged diameter part 12 is provided in the internal peripheral surface 11 of the filling member 1, depending on the case, this enlarged diameter part 12 does not need to be provided. In this case, it is possible to prevent the front end portion 5x of the moving screw cylinder 5 from expanding even if the moving screw cylinder 5 is in the retreat limit.

  Further, in the above embodiment, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in one direction / other direction, the screwing action of the first screwing part 8 works and at the same time the second screwing part 9. However, it may be configured such that only the screwing action of the second screwing part 8 works after only the screwing action of the first screwing part 8 works. . Further, the male screw and the female screw described above are not only a screw thread or a screw groove, but also a thread group or a screw groove such as an intermittently arranged protrusion group or a spiral and intermittently disposed 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.
