  Next, an example of a manufacturing method of the screw cylinder 31 in the operation cylinder 3 of the coating material extruding container 100 having such a configuration will be described with reference to FIG.

  First, a pair of core pins 50 (50a, 50b) are butted so as to face each other, and a split mold (molded outer mold, not shown) is disposed so that these core pins 50a, 50b are surrounded by a predetermined amount, and a molten resin Is injected between the inner peripheral surface of the split mold and the outer peripheral surface of the core pin 50. Thereby, the molten resin flows into the gap between the inner peripheral surface of the split mold and the core pin 50 and between the core pins 50a and 50b, and then the molten resin is solidified to form the screw cylinder 31.

  The core pins 50a and 50b have shapes corresponding to each other on their respective front end surfaces. One core pin 50a is provided with a concave portion 52a that is recessed in a circular shape when viewed in the axial direction at the center of the front end surface, and the concave portion 52a is provided at the center of the front end surface of the other core pin 50b.

In addition, a convex portion 53a is provided in parallel along the circumferential direction on the outer edge around the concave portion 52a on the tip surface of one core pin 50a. The protrusions 53a are provided in the number corresponding to the number of the protrusions 33 of the screw cylinder 31 (six equally distributed along the circumferential direction), and are formed in a mountain shape inclined to one side in the circumferential direction. And the circular-arc-shaped recessed part 54a extended along the circumferential direction is formed in the outer edge part of the slope of each convex part 53a. Similarly to the convex portion 53a, the other core pin 50b is provided with a plurality of convex portions 53b along the circumferential direction, and the convex portion 53b is provided with an arcuate concave portion 54b. These convex portions 53a and 53b face each other when the core pins 50a and 50b are abutted, and the gap between the concave portions 54a and 54b corresponds to the protruding portion 33.

  One core pin 50a is provided with an uneven portion 55 including an uneven first half portion 55x corresponding to the first half portion 32a of the knurl 32 and an uneven second half portion 55y corresponding to the second half portion 32b of the knurl 32. It has been.

  Then, when such a core pin 50 is used to mold the screw cylinder 31 having the projection 33 by injecting molten resin, in this embodiment, the core pins 50a and 50b are opposite to each other in the insertion direction (front side, rear side in the figure). ). Then, as described above, the protrusions 33 do not overlap with each other when viewed in the axial direction, that is, there is no other protrusion 33 in the extraction path of the core pin 50, so that the core pin 50 is not forcedly removed. There is no need to unscrew. Therefore, when forming the screw cylinder 31, the core pins 50a and 50b can be pulled out to the front side and the rear side, so that the coating material extruding container 100 can be easily and quickly formed, and the manufacture is facilitated. Yes.

  Further, as described above, since the protrusion 33 is formed by a gap formed by abutting the pair of core pins 50a and 50b, the protrusion end on the unwinding side is formed as in the case where the protrusion extends spirally. The portion does not have an acute edge, and the strength and durability can be suppressed.

  In the coating material extruding container 100 in the initial state shown in FIG. 1 having the above-described configuration, the coating material M filled with the molten resin in the filling region 1x and solidified is the inner peripheral surface of the filling member 1 and the piston 7. Is in close contact with the Here, between the coating material M and the piston 7, a filler having adhesiveness and fluidity with a composition different from that of the coating material M is used to enhance the adhesion and followability between the coating material M and the piston 7. A small amount (not shown) can be interposed. When the cap 10 is removed by the user and the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the feeding direction (one direction), the filling member 1, the moving screw cylinder 5 and the moving body 6 are relatively rotated. In addition, the moving screw cylinder 5 and the screw cylinder 31 of the operation cylinder 3 rotate relative to each other. Accordingly, the screwing action of the first screwing portion 8 constituted by the male screw 5e of the moving screw tube 5 and the projection 33 of the screw tube 31 is activated, and the protrusion 5b of the moving screw tube 5 and the filling member 1 are moved. The moving screw cylinder 5 moves forward by cooperation with the rotation preventing portion constituted by the knurl 1c, and at the same time, a second screw constituted by the female screw 5d of the moving screw cylinder 5 and the male screw 6b of the moving body 6. The screwing action of the screwing portion 9 is activated, and the moving body 6 is also cooperated with the rotation preventing portion constituted by the protrusion 35g of the shaft body 35y and the protrusion 6f of the moving body 6 in the tail plug 35. Advance. In other words, the moving body 6 advances along with the moving screw cylinder 5 and simultaneously advances alone.

  When the main cylinder 2 and the operation cylinder 3 continue to rotate relative to each other in the extending direction, the locking portion 5a of the moving screw cylinder 5 contacts the front half portion 32a of the knurling 32 of the screw cylinder 31, as shown in FIG. The spring portion 5z of the moving screw cylinder 5 is extended and the male screw 5e of the moving screw cylinder 5 is disengaged from the tip of the protrusion 33 of the screw cylinder 31, and the first screwing portion 8 is screwed. The combination is released and the moving screw cylinder 5 reaches the forward limit.

  Then, in the state where the screwing is released at the time of forward movement, the male screw 5e of the moving screw cylinder 5 is urged rearward by the elastic force of extension in the spring portion 5z of the moving screw cylinder 5. Accordingly, when the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction is further continued, the male screw 5e of the moving screw cylinder 5 enters the tip of the protrusion 33 of the screw cylinder 31 adjacent to the rotation direction and enters the first position. One screwing portion 8 is screwed back. When the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction is further continued, the moving screw cylinder 5 moves forward while the spring portion 5z is extended, and the male screw 5e of the moving screw cylinder 5 becomes the screw cylinder. 31 is released from the tip of the projecting portion 33, and the screwing is released, and the screwing is restored by further relative rotation in the same direction. Repeated.

  In addition, the screwing action of the first screwing portion 8 works in this way, the moving screw cylinder 5 moves forward by a predetermined amount and reaches the forward limit, and the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction continues. In the state where the screw release and screw return of the first screwing part 8 are repeated (the screwing action of the first screwing part 8 is not substantially activated) Only the screwing action of the second screwing portion 9 works, and only the moving body 6 moves forward.

  Here, in a state where the moving screw cylinder 5 reaches the advance limit and only the moving body 6 moves forward, as described above, the first screwing is performed by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction. Since the screw release and screw return of the part 8 are repeated, this causes a click feeling, and the degree of relative rotation in the feed-out direction and the moving state of the moving body 6 are suitably detected by the user, and Only the moving body 6 moves forward by the relative rotation accompanied by a click feeling in the feeding direction of the main body cylinder 2 and the operation cylinder 3, and the coating material M is pushed out by the piston 7 at the tip and appears through the opening 1a. Therefore, the first screwing portion 8 is used as a click mechanism for generating a click feeling, and the user can be made to detect that the coating material M appears from the opening 1a with a click feeling, and the coating material M is filled. Excessive extrusion from the opening 1a of the member 1 can be prevented with a simple structure.

  At this time, as described above, since the lead of the second screwing portion 9 is set to be smaller than the lead of the first screwing portion 8, the moving body 6 is slowly drawn out. M can be further prevented from being excessively extruded.

  On the other hand, after the use, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the rewinding direction (other direction), the male screw 5e of the moving screw cylinder 5 biased rearward is When the first threaded part 8 enters the tip of the projecting part 33 and the first threaded part 8 is screwed back, and the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the rewinding direction is further continued, the first threaded part 8 And the screwing action of the 2nd screwing part 9 act | operates, the moving screw cylinder 5 reverse | retreats, and the moving body 6 also reverses with respect to the moving screw cylinder 5. FIG. In other words, the moving body 6 is retracted along with the moving screw cylinder 5 and is also retracted alone.

  When the moving screw cylinder 5 and the moving body 6 retreat in this way, as described above, the piston 7 comes into close contact with the inner peripheral surface of the filling member 1, and the coating material M comes into close contact with the inner peripheral surface of the filling member 1. 7 and the coating material M are in close contact with each other, and as the piston 7 moves backward, a suction action (an action to maintain the close contact) is exerted between the piston 7 and the coating material M so that the coating material M is a filling member. When the coating material M appears back from the opening 1a of the filling member 1 and retracts, the coating material M quickly immerses from the opening 1a. Further, as described above, since the filler having adhesiveness and fluidity is interposed between the coating material M and the piston 7, the adhesion and followability between the coating material M and the piston 7 are improved. As the piston 7 moves backward, the coating material M is reliably pulled back and moves backward. Further, when the filler enters between the coating material M and the filling member 1, the slidability between the coating material M and the filling member 1 is enhanced, and the coating material M is lowered in temperature as the piston 7 moves backward. It is possible to move back more reliably even underneath.

  When the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction is continued, the moving screw cylinder 5 reaches the retreat limit, and the rear end surface of the spring portion 5z of the moving screw cylinder 5 is The male screw 5e of the moving screw cylinder 5 comes off from the rear end of the projecting portion 33 of the screw cylinder 31 while the spring part 5z of the moving screw cylinder 5 is compressed by the further relative rotation while contacting the bottom surface of the tail plug 35. The screwing of one screwing part 8 is released.

  When the screw is released during retraction, the male screw 5e of the moving screw cylinder 5 is urged forward by the elastic force of compression in the spring portion 5z of the moving screw cylinder 5. Therefore, when the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction is further continued, the male screw 5e of the moving screw cylinder 5 enters the rear end of the protrusion 33 of the screw cylinder 31 adjacent to the rotation direction. The first screwing portion 8 is screwed back. When the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction is further continued, the moving screw cylinder 5 moves backward while the spring portion 5z is compressed, and the male screw 5e of the moving screw cylinder 5 is screwed. The screw 31 is released from the rear end of the projecting portion 33 of the cylinder 31, and the screwing is released by the relative rotation in the same direction. The screwing release and screwing of the first screwing portion 8 are performed. The return is repeated.

  In addition, the screwing action of the first screwing portion 8 works in this way, the moving screw cylinder 5 moves backward by a predetermined amount to reach the retreat limit, and the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction is performed. In a state where the screw release and screw return of the first screwing part 8 are repeated (the screwing action of the first screwing part 8 is not substantially activated). Only the screwing action of the second screwing portion 9 works, and only the moving body 6 moves backward.

  Here, when the moving screw cylinder 5 reaches the retreat limit and only the moving body 6 retreats, as described above, the first screw is rotated by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction. Since the unscrewing and the unscrewing of the joint portion 8 are repeated, this causes a click feeling, and the degree of relative rotation in the retraction direction and the moving condition of the moving body 6 are suitably sensed by the user, Then, only the moving body 6 is retracted by the relative rotation accompanied by a click feeling in the retraction direction between the main body cylinder 2 and the operation cylinder 3, and the coating material M is pulled back. Accordingly, even when only the moving body 6 is retracted, the first screwing portion 8 is used as a click mechanism for generating a click feeling, and the user senses that the coating material M is pulled back with a click feeling. It is possible to prevent the coating material M from being pulled back excessively with a simple structure. As a result, when the coating material M is pushed out next time, the time it takes for the coating material M to appear from the opening 1a of the filling member 1 after the main body tube 2 and the operation tube 3 start to rotate relative to each other in the feeding direction is shortened. The coating material M can be made to appear immediately from the opening 1 a of the filling member 1.

  At this time, as described above, since the lead of the second screwing portion 9 is set to be smaller than that of the first screwing portion 8, the moving body 6 is slowly fed back. Can be further prevented from being pulled back excessively.

  Thereafter, the same operation as described above is performed, and such an operation is repeated. Further, as shown in FIG. 3, when the piston 7 moves forward to the maximum by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the feeding direction, the coating material M is almost used up.

  As described above, according to the coating material extruding container 100 of the present embodiment, when the first screwing portion 8 is unscrewed and further rotated relative to one direction / the other direction, the first screwing portion 8. The screw release and the screwing return by the spring portion 5z of the moving screw cylinder 5 are repeated, and a click feeling is generated, and the degree of relative rotation and the moving state of the moving body 6 are perceived by the user. That is, the first screwing portion 8 is used as a click mechanism for generating a click feeling, and the application material M is prevented from being excessively pushed out / retracted with a simple structure.

  Further, in this embodiment, both the elastic force of expansion and compression of the spring portion 5z is applied to both the screwing return when the moving body 6 moves forward and backward and the first screwing portion 8 is unscrewed. Since the spring portion 5z is also used, the spring portion 5z is screwed back to the male screw 5e of the moving screw cylinder 5 only when the moving body 6 moves forward and backward. The male screw 5e and the spring part 5z can be made into an integral part. Therefore, the number of parts of the coating material extruding container 100 can be reduced.

  In addition, as described above, the present embodiment includes the locking portion 5a that locks the spring portion 5z in the container so that the elastic force of extension of the spring portion 5z is applied. Therefore, the spring portion 5z can be locked to the front half portion 32a of the knurl 32 of the screw cylinder 31 by the locking portion 5a, so that the spring portion 5z can be suitably extended, and the elastic force of extension of the spring portion 5z is applied to the first screwing. It can be suitably applied so that the portion 8 is screwed back.

  In the coating material extruding container 100 of the present embodiment, as described above, the protrusions 33 are arranged equally on the inner peripheral surface of the screw cylinder 31 of the operation cylinder 3 along the circumferential direction. A plurality of screw cylinders 31 may be provided along the circumferential direction on the inner peripheral surface of the screw cylinder 31. For the following reason, it is preferable that four or more protrusions 33 are provided on the inner peripheral surface of the screw cylinder 31 along the circumferential direction.

  That is, the larger the number of clicks per rotation, the easier it is for the coating material M to appear in small amounts. Therefore, if the number of protrusions 33 is three or less, the number of clicks per rotation is small and the coating material M is pushed out excessively. This is because the above-described effect of preventing the occurrence of the problem may be insufficient.

  Further, the more protrusions 33 are provided, the more complicated the shape of the core pins 50a and 50b. From the viewpoint of manufacturing the coating material extruding container 100, the number of protrusions 33 is preferably small. Therefore, in view of both the viewpoints of reliably preventing the coating material M from being excessively extruded / retracted and the above viewpoints of the manufacturing surface of the coating material extruding container 100, the protruding portion 33 is connected to the screw cylinder of the operation cylinder 3. Six to eight are preferably provided on the inner peripheral surface of 31 along the circumferential direction, and six protrusions 33 are more preferably provided as in the present embodiment. As described above, when six protrusions 33 are provided on the inner peripheral surface of the screw cylinder 31 of the operation cylinder 3 along the circumferential direction, and the male screw 5e of the moving screw cylinder 5 is a twelve thread as described above, There will be 12 clicks per relative rotation. Incidentally, eight protrusions 33 are provided along the circumferential direction, and the male screw 5e may be an eight-thread screw. In this case, a click feeling is generated eight times per one relative rotation.

It has become.

  The manufacturing method of such a screw cylinder 104 is the same as the manufacturing method in the screw cylinder 31 of the coating material extruding container 100 of the first embodiment.

  The moving screw cylinder 105 is an injection-molded product made of resin, and is configured in a stepped cylindrical shape as shown in FIGS. 30 to 32. The moving screw cylinder 105 is connected to the rear outer diameter large diameter portion 105y via a step surface 105p. The outer diameter small diameter part 105x of the front side is provided.

  On the outer diameter small diameter portion 105x of the moving screw cylinder 105, a protrusion 105b extending in the axial direction at four positions along the circumferential direction on the outer peripheral surface in the center in the axial direction rotates the protrusion 110f of the rotating member 110.

  A threaded projection (spiral projection) 105e constituting the other (male screw) of the first threaded portion 8 is opposed to the outer diameter surface 105y of the moving screw cylinder 105 on the outer peripheral surface on the tip side. A plurality of them are provided. Further, in the outer diameter / large diameter portion 105y, a spring portion 105a, which is a so-called resin spring (biasing means) that can be expanded and contracted in the axial direction, is integrally connected to the rear side of the screw projection 105e. ing. Further, the outer diameter / large diameter portion 105y has an annular flange 105c on the outer peripheral surface on the rear side of the spring portion 105a. As shown in FIG. 19, the flange 105 c comes into contact with the rear end surface of the screw cylinder 104 when the moving screw cylinder 105 moves forward, and functions as a forward limit locking portion of the moving screw cylinder 105.

  As shown in FIG. 18, this moving screw cylinder 105 is inserted into the moving body 6 and inserted into the screw cylinder 104, and the female screw 105d is screwed into the male screw 6b of the moving body 6. The second screwing portion 9 is configured.

  In the coating material extruding container 200 in the initial state shown in FIG. 18 configured as described above, when the filling member 1 and the main body cylinder 102 are relatively rotated in the feeding direction, the screwing of the first screwing portion 8 is performed. The combined action is activated, and the moving screw cylinder 105 is moved forward by cooperation with the rotation preventing portion composed of the protrusions 110f and 105b. At the same time, the screwing action of the second screwing portion 9 is activated, and the protrusion 102d, The moving body 6 also moves forward by the cooperation with the rotation stop portion composed of 6f.

  Subsequently, when the moving screw cylinder 105 moves forward by a predetermined amount, as shown in FIG. 19, when the flange 105 c comes into contact with the rear end surface of the screw cylinder 104 and is further relatively rotated in the feeding direction, the spring of the moving screw cylinder 105 is moved. While the portion 105a is extended, the screwing projection 105e of the moving screw tube 105 is disengaged from the tip of the protrusion 104d of the screw tube 104, the screwing of the first screwing portion 8 is released, and the relative movement in the further feeding direction is released. According to the rotation, the first screwing portion 8 is screwed back by the elastic force of extension in the spring portion 105a of the moving screw cylinder 105, and this screwing release and screwing return are repeated. When the relative rotation is further performed in the same direction, only the screwing action of the second screwing part 9 works while the screwing release and screwing of the first screwing part 8 are repeated, and the moving body 6 Only advancing with a feeling of clicking, the coating material M is appropriately pushed out by the piston 107 at the tip, appears through the opening 1a, and is put into use.

  On the other hand, after the use, when the filling member 1 and the main body cylinder 102 are relatively rotated in the retraction direction, the first screwing section 8 is screwed by the elastic force of the extension of the spring section 105a of the moving screw cylinder 105. By returning and further rotating in the same direction, the screwing action of the first screwing portion 8 and the second screwing portion 9 is activated, and the moving screw tube 105 is retracted, and at the same time, Then, the moving body 6 also moves backward, and the coating material M is pulled back in the filling member 1 by the suction action by the pressure reduction according to the backward movement of the piston 107 and moves backward.

  Subsequently, when the moving screw cylinder 105 moves backward by further relative rotation in the same direction, the rear end surface of the moving screw cylinder 105 comes into contact with the bottom surface of the main body cylinder 102 as shown in FIG. When the relative rotation is further performed in the same direction, the spring portion 105a of the moving screw cylinder 105 is compressed, the moving screw cylinder 105 is retracted, and the screwing protrusion 105e of the moving screw cylinder 105 is the tip of the protrusion 104d of the screw cylinder 104. The first screwing portion 8 is released, and the first screwing portion 8 is screwed by the elastic force of compression in the spring portion 105a of the moving screw cylinder 105 in accordance with the relative rotation in the rewinding direction. The joint is restored, and the screw release and the screw return are repeated. When the relative rotation is further performed in the same direction, only the screwing action of the second screwing part 9 works while the screwing release and screwing of the first screwing part 8 are repeated, and the moving body 6 Only retreats with a click. When the piston 107 moves forward by the relative rotation of the filling member 1 and the main body cylinder 102 in the feeding direction, the coating material M is almost used up as shown in FIG.

  Needless to say, according to the coating material extruding container 200 of this embodiment, substantially the same effect as that of the first embodiment can be obtained.

As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment.

  For example, in the second embodiment, the screw cylinder 104 that engages with the main body cylinder 102 in the rotational direction and the axial direction around the axis is disposed in the main body cylinder 102, and the protrusion 104 d is disposed on the inner surface of the screw cylinder 104 in the circumferential direction. However, a plurality of protrusions may be provided along the circumferential direction on the inner surface of the main body cylinder 102 without having a screw cylinder.

  Further, in the above embodiment, as the urging means, the moving screw cylinders 5 and 105 are integrally provided with the spring portions 5z and 105a which are so-called resin springs that can be expanded and contracted in the axial direction. May be provided integrally, or may be provided integrally with a flexible soft material (for example, synthetic resin such as urethane resin or silicone resin, rubber, etc.).

  The male screw and the female screw may function in the same manner as a screw thread, such as a group of protrusions arranged intermittently or a group of protrusions arranged helically and intermittently.

  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.

  In the above embodiment, when the container front part and the container rear part are relatively rotated in one direction / other direction, the screwing action of the first screwing part 8 is activated and the second screwing part 9 is simultaneously operated. Although the screwing action is configured to be activated, only the screwing action of the first screwing portion 8 may be activated.
