Description

  The present invention relates to a filler extrusion container for extruding a filler for use.

Conventionally, as a cosmetic delivery container, a tip cylinder and a shaft cylinder constituting the outer shape of the container are connected so as to be relatively rotatable, and an intermediate shaft cylinder and a core chuck for holding cosmetics are provided in the container so as to be movable in an axial direction The first spiral groove provided on the inner peripheral surface of the cylinder and the protrusion provided on the outer surface of the rear end portion of the intermediate shaft cylinder constitute the first threaded portion, and the second provided on the inner peripheral surface of the intermediate shaft cylinder There is known that a second screwing portion is formed by a protrusion provided on the outer surface of the rear end portion of the spiral groove and the core chuck, thereby providing a double-structure feeding mechanism (for example, see Patent Document 1). . In this Patent Document 1, when the leading tube and the shaft tube are rotated relative to each other, the screwing action of the first screwing portion is actuated first, and the intermediate shaft moves forward with the core chuck. When the cylinder reaches the forward limit, the screwing action of the second screwing portion is activated and the lead chuck is advanced. Further, Patent Document 1 describes that the pitch of the first spiral groove and the second spiral groove can be made different. Accordingly, if the pitches of the first spiral groove and the second spiral groove are made different from each other in this way, until the intermediate shaft tube reaches the forward limit due to the relative rotation of the leading tube and the shaft tube in the feeding direction, the cosmetics Advances at the first speed by the screwing action of the first screwing part, and further continues to rotate in the feeding direction, the cosmetic is brought to the first speed by the screwing action of the second screwing part. Will be able to move forward at a different second speed. That is, two-stage feeding can be performed at different speeds. For example, the delivery specifications can be set such that cosmetics are quickly delivered by the first delivery and the cosmetics are delivered slowly by the second delivery. .

  However, in practice, the first screwing portion does not surely work first, and the second screwing portion may work first, so the speed was changed. Two-stage feeding as set is not always possible.

  The present invention has been made to solve such a problem, and includes various feedings with a variety of variety, including reliably performing two-stage feeding / returning as set at different speeds, It is an object of the present invention to provide a filler extrusion container that enables a combined operation of rewinding.

  The filled material extruding container according to the present invention includes a filled material filled in a filling region in the container, and when the container front part and the container rear part made relatively rotatable with the container front part are relatively rotated, And a movable body disposed in the container for advancing / retreating, pushing the filler forward to move forward, or pulling the filler back and backward, wherein the first screwing portion and the second threading container are disposed in the container. When the container front part and the container rear part are relatively rotated in one direction with the screwing part, the screwing action of the first screwing part and the second screwing part work together to advance the moving body, When the screwing action of the first screwing part works for a certain interval corresponding to the relative rotation of the container front part and the container rear part in one direction, the screwing of the first screwing part is released, and further in one direction When the relative rotation is performed, only the screwing action of the second screwing portion works and the moving body moves forward / backward.

  According to such a filling extrusion container, the movable body moves forward by the screwing action of the first screwing portion and the second screwing portion in the fixed section, and the second screwing section exceeds the fixed section. Since the moving body moves forward / backward only by the screwing action, various kinds of moving bodies that are rich in variety are fed out and fed back, including reliable two-stage feeding of the moving body as set at different speeds. Can be combined.

  As a specific example, for example, the lead of the first screwing part advances 3 mm with respect to one rotation of the relative rotation of the container front part and the container rear part, and the lead of the second screwing part advances 1 mm with respect to one rotation. By setting, the moving body moves forward by 4 mm for one rotation in a certain section, and when moving beyond a certain section, the moving body moves forward by 1 mm for one rotation, that is, the certain section quickly moves forward and exceeds a certain section. It is possible to move slowly. Further, for example, by setting the lead of the first screwing portion to 1 mm with respect to one rotation and setting the lead of the second screwing portion to a reversely advanced screw that advances by 2 mm with respect to one rotation, a predetermined interval The moving body moves forward by 1 mm for one rotation, and when the predetermined section is exceeded, the moving body advances by 2 mm for one rotation, that is, the fixed section slowly moves forward, and when the predetermined section is exceeded, the moving body moves forward quickly. it can. In addition, for example, by setting the lead of the first screwing portion to advance by 3 mm with respect to one rotation and setting the lead of the second screwing portion to reverse by moving backward by 2 mm with respect to one rotation, the predetermined interval is set. The moving body moves forward by 1 mm for one rotation, and when moving beyond a certain section, the moving body moves backward by 2 mm. That is, the moving section slowly moves forward by one rotation, and quickly moves backward after exceeding a certain section. it can. Further, for example, by setting the lead of the first screwing portion to advance by 4 mm for one rotation and setting the lead of the second screwing portion to reverse by going back by 1 mm for one rotation, the predetermined interval is set. The moving body moves forward by 3 mm for one rotation, and when moving beyond a certain section, the moving body moves backward by 1 mm, that is, the moving section moves forward rapidly by one section, and slowly moves backward after exceeding a certain section. it can. In addition, for example, by setting the lead of the first screwing portion to advance by 2 mm with respect to one rotation and setting the lead of the second screwing portion to reverse by going backward by 1 mm with respect to one rotation, the predetermined interval is set. The moving body moves forward by 1 mm for one rotation, and when moving beyond a certain section, the moving body moves backward by 1 mm. That is, the moving section moves forward by one section, and when moving beyond a certain section, moves backward at the same speed as the certain section. It can be. In addition, the same speed here is a case where it compares with the fixed rotation speed of the relative rotation of one direction.

When the moving body is retracted and the screwing action of the first screwing part works for a certain period corresponding to the relative rotation between the container front part and the container rear part in one direction, the screwing of the first screwing part is When it is released and further rotated in one direction, only the screwing action of the second screwing part works and the moving body moves backward / forward. It is a symptom.

  According to such a filling product extruding container, the movable body moves backward due to the screwing action of the first screwing portion and the second screwing portion in the fixed section, and the second screwing section exceeds the fixed section. Since the moving body moves backward / forward by only the screwing action, it is rich in variety as in the above-mentioned specific examples, including reliably performing the two-stage rewinding of the moving body as set with the speed changed. However, it is possible to combine various movements of the moving body.

A configuration is also possible in which the moving body can rotate synchronously with the operation cylinder and can move in the axial direction, and moves forward / backward by relative rotation between the filling member and the main body cylinder and the operation cylinder.

  Here, an urging means for urging the first screwing portion to be screwed back when the moving body moves forward / backward in a certain section and the screwing of the first screwing portion is released. It is preferable to provide. In the case of adopting such a configuration, when the first screwing portion is released, the first screwing portion is screwed back by the biasing force of the biasing means. And the rear part of the container are rotated relative to each other so that the moving body moves forward / backward in the direction in which the first screwing part returns to the screwing state, the screwing action of the first screwing part works without trouble and the moving body moves forward. / Comes back. Further, when the screwing of the first screwing part is released and the container front part and the container rear part are relatively rotated, the moving body moves forward / backward in the direction in which the first screwing part is released. , The screw release of the first screwing portion and the screwing return by the urging means are repeated, whereby a click feeling is generated, and the degree of relative rotation and the moving condition of the moving body are perceived by the user. .

  The screw cylinder 4, the moving screw cylinder 5, the moving body 6, the rotating member 10, and the intermediate member 11 are made of an injection molding material having high slidability such as POM (polyacetal) or UHMWPE (ultra high molecular weight polyethylene). Is preferred.

  As shown in FIG. 1, the filling member 1 is for filling the filling region 1q with the filling material M, and for causing the filling material M to appear from the tip according to the operation by the user. is there. The filling member 1 and the cap 12 are formed of an injection molding material such as ABS, PP (polypropylene), PET (polyethylene terephthalate), or PCT (polycyclohexanedimethylene terephthalate) based PETG, PCTG, PCTA, etc. It is preferable to use a transparent material, or a coloring material to which the color of the filling material M or other colors is applied so that the color tone and the filling state of the material can be confirmed from the outside.

  As shown in FIG.1 and FIG.20, the filling member 1 is comprised by the stepped cylindrical shape, and is provided with the small diameter part 1y of the rear side, and the large diameter part 1x of the front side from this via the level | step difference surface 1e. . The large-diameter portion 1x has a shape whose outer periphery is slightly tapered toward the tip, and the opening 1a at the tip is an opening for causing the filler M to appear. Further, here, as shown in FIG. 1, the front end surface of the filling member 1 and the front end surface of the filler M are inclined surfaces that are inclined with respect to a plane perpendicular to the axis as viewed from the direction perpendicular to the plane of FIG. Has been.

  As shown in FIG. 20, on the inner peripheral surface of the rear end portion of the small diameter portion 1y, an annular concavo-convex portion 1b is provided so as to engage with the annular convex concavo-convex portion 10d of the rotating member 10 in the axial direction. On the inner peripheral surface on the front side of the annular concavo-convex portion 1b, a large number of concavo-convex portions are arranged side by side in the circumferential direction, and the knurl 1c in which the concavo-convex portion extends in a predetermined length in the axial direction rotates in the protrusion 10e of the rotating member 10 It is provided to be engaged with.

  As shown in FIG. 1, the filling member 1 is inserted between the rotating member 10 and the piston 7 and the intermediate member 11 from the rear side, and the rear end surface is in contact with the flange portion 10 c of the rotating member 10, The portion 1b is engaged with the annular convex recess 10d of the rotating member 10 in the axial direction, and the protrusion 10e of the rotating member 10 is engaged with the knurling 1c in the rotating direction. It is mounted so that it cannot be detached, and is integrated with the rotating member 10. As described above, the rotating member 10 is prevented from detaching forward in the axial direction by the intermediate member 11 integrated with the main body cylinder 3 and can be rotated synchronously with the moving screw cylinder 5. Is screwed to the moving body 6 via the second screwing portion 9, and the moving body 6 can rotate synchronously with the main body cylinder 3. It is mounted so that it can rotate relative to the shaft and cannot be removed in the axial direction. Further, a piston 7 (annular protrusion 7 c) is inserted into the rear end portion of the filling member 1 so as to be in close contact with the filling member 1.

  As shown in FIG. 1, the filling member 1 is protected by the cap 12 by the cap 12 being detachably attached to the intermediate member 11.

  Next, an example of a manufacturing procedure of the filler extrusion container 100 having such a configuration will be described with reference to FIG. First, the moving screw cylinder 5 is screwed into the moving body 6 to the initial position. Alternatively, the screw thread is forcibly moved over and pushed to the initial position. Next, the rotating member 10 is extrapolated to the moving screw cylinder 5 so that the protrusion 5b of the moving screw cylinder 5 is engaged between the protrusions 10f, 10f of the rotating member 10, and then the piston 7 is attached to the moving body 6. Furthermore, the outer diameter large diameter portion 5 y of the moving screw cylinder 5 is inserted from the large diameter portion 4 x of the screw cylinder 4, and the female screw on the inner peripheral surface of the screw cylinder 4 is inserted into the screwing protrusion 5 e of the outer peripheral surface of the moving screw cylinder 5. 4d is screwed, rotated in the rewinding direction and retracted to a predetermined position to obtain a temporary assembly.

  Next, the temporary assembly is inserted from the opening side of the main body cylinder 3, and the movable body 6 is fixed to the shaft body while engaging the protrusion 6f of the movable body 6 between the protrusions 3d and 3d of the shaft body 3y of the main body cylinder 3. The screw cylinder 4 is inserted into the main body cylinder 3 while the protrusion 4a of the screw cylinder 4 is engaged between the protrusions 3c and 3c of the main body cylinder 3, and the spring portion of the moving screw cylinder 5 is inserted. The rear end surface of 5a is brought into contact with the bottom surface of the main body cylinder 3. Next, the intermediate member 11 is inserted and attached to the main body cylinder 3, and the intermediate member 11 makes the screw cylinder 4 unremovable forward in the axial direction via the rotating member 10 and the rotating member 10. can get.

  On the other hand, in the filling member 1, a predetermined amount of the molten filling material M <b> 1 is discharged from the nozzle 14 in the state where the opening 1 a at the front end is closed with the sealing member 13 and inverted, and from the front end to the rear end of the filling member 1. It is made to be in a state where there is no space in the front end of the filling member 1 by filling in part. When the molten filler M1 is cooled and solidified to become the filler M, the front end side of the main assembly 40 is extrapolated from above with respect to the filling member 1 filled with the filler M, and the piston 7 is filled. While being inserted into the member 1, the filling member 1 is attached to the main body cylinder 3 (intermediate member 11). At this time, the inner peripheral surface of the filling member 1 is engaged with the main body cylinder 3 while being in sliding contact with the annular protrusion 7 c for ensuring the airtightness of the piston 7.

  Then, when the sealing member 13 is removed from the thus-obtained filler extrusion container, an initial state of the filler extrusion container 100 is obtained as shown in FIG. The seal member 13 is hygienic when removed by the user (consumer) after purchase. Further, the internal shape of the cap 12 can be changed to be used also as the seal member 13.

  In other manufacturing procedures, as shown in FIG. 22, first, the filling member 1 is mounted on the main assembly 40, and this assembly is placed so that the inclined front end surface 1z of the filling member 1 is horizontal. In addition to being set on the jig 41, a cylindrical heat retaining member 15 made of, for example, a rubber material is extrapolated and set on the tip of the filling member 1. At this time, the inner peripheral surface of the heat retaining member 15 is provided with a step portion 15a having a large inner diameter on the rear side (the lower side in the drawing), and the front end surface 15b constituting the step portion 15a is the filling member 1. The inner peripheral surface in front of the step portion 15a of the heat retaining member 15 and the opening 1a at the tip of the filling member 1 are substantially flush with each other.

  Next, the molten filling material M1 is discharged from the nozzle 14 located above the opening at the tip of the heat retaining member 15, and the molten filling material M1 is filled from the piston 7 side, and is filled slightly more. At this time, it is difficult to entrain air between the piston 7 and the molten filler M1, and it is good for pulling back the filler M by the suction action caused by the retraction of the piston 7. Further, the heat retaining member 15 prevents a large amount of the molten filling material M <b> 1 from dripping from the tip of the filling member 1.

  The molten filler M1 is cooled and solidified. At this time, the heat retaining member 15 keeps the tip side of the filling member 1 warm, so that the molten filler M1 gradually moves from the piston 7 side toward the tip of the filling member 1. The bubbles in the molten filler M1 are well removed from the upper end of the molten filler M1, and the bubbles are prevented from remaining in the filler.

  When the molten filler M1 is cooled and solidified, the heat retaining member 15 is removed, and the tip of the filler M is cut and finished to obtain the initial state of the filler extrusion container 100 shown in FIG.

  According to the filler extrusion container 100 configured in this manner, as shown in FIG. 1, only the cylindrical filler member 1 is filled with the filler M, so that the thickness of the filler member 1 is relatively uniform. The thickness of the packing M in the radial direction is constant along the axial direction, and it is possible to stabilize the temperature conditions from filling the molten packing M1 to solidification. As a result, it is possible to satisfactorily fill the filler M, and the production yield is improved.

  Further, in the filling product extruding container shown in FIG. 21, since the filling member 1 filled with the filling material M is assembled to the main assembly 40, the manufacture is facilitated. Since the filling member 1 assembled in the main assembly 40 is filled with the filling material M, the manufacturing is further facilitated.

  In addition, since the filling member 1 filled with the filling material M is assembled to the main assembly 40 or the filling member 1 assembled to the main assembly 40 is filled with the filling M, the filling member 1 is soft. Even a semi-solid bar, a thin and brittle bar, a soft, jelly or mousse bar can be safely protected by the filling member 1.

  In this state, the piston 7 is in close contact with the inner peripheral surface of the filling member 1, the filler M is in close contact with the inner peripheral surface of the filling member 1, and the piston 7 and the filler M are in close contact with each other.

  In the filling extrudate container 100 in the initial state shown in FIG. 1 configured as described above, when the cap 12 is removed by the user and the filling member 1 and the main body cylinder 3 are relatively rotated in the feeding direction, The screw cylinder 4 that rotates synchronously with the main body cylinder 3 by the rotation preventing portion 60 between the rotating member 10 that rotates synchronously with the filling member 1 and the moving screw cylinder 5 and the rotation stopper 50 between the main body cylinder 3 and the moving body 6. The moving screw cylinder 5 is relatively rotated, and the moving screw cylinder 5 and the moving body 6 are relatively rotated. Therefore, from the first screwing portion 8 constituted by the screwing projection 5e of the moving screw cylinder 5 and the female screw 4d of the screw cylinder 4, and from 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 configured second screwing portion 9 is activated, the moving screw cylinder 5 moves forward, and the moving body 6 also moves forward relative to the moving screw cylinder 5. In other words, the moving body 6 advances along with the moving screw cylinder 5 and simultaneously advances alone.

  At this time, as described above, the lead of the first screwing portion 8 advances 8 mm with respect to one rotation of the relative rotation between the filling member 1 and the main body cylinder 3, and the lead of the second screwing portion 9 makes one rotation. On the other hand, since it is set to advance by 0.5 mm, the moving screw cylinder 5 advances large and quickly (8 mm for one rotation), and the moving body 6 itself advances small and slowly (0.5 mm for one rotation). Therefore, the moving body 6 moves forward from the initial position shown in FIG. 1 by adding a small amount of advancement of the moving body 6 itself to the large amount of advancement of the moving screw cylinder 5 (8.5 mm for one rotation). That is, the moving body 6 moves forward quickly by the cooperative action of the first and second screwing portions 8 and 9.

  Then, when the moving screw cylinder 5 quickly advances in this manner, the stepped surface 5p of the moving screw cylinder 5 comes into contact with the rear end surface of the spring portion 10y of the rotating member 10 as shown in FIG. 3, while the spring portion 10 y of the rotating member 10 is compressed and stores the urging force, the moving screw cylinder 5 moves forward, and the screwing protrusion 5 e of the moving screw cylinder 5 is connected to the screw cylinder 4. The first screw 8 is released from the tip of the female screw 4d, and the first screw 8 is released.

  In this unscrewed state, the moving screw cylinder 5 is urged rearward by the urging force of the spring portion 10y of the rotating member 10. Therefore, when the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction is further continued, the screwing projection 5e of the moving screw cylinder 5 biased rearward is connected to the female screw 4d in the screw cylinder 4. The first screwing portion 8 is screwed and returned to the tip adjacent to the rotation direction. When the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction is further continued, the moving screw cylinder 5 moves forward while the spring portion 10y of the rotating member 10 is compressed, and the moving screw cylinder 5 is screwed. The protrusion 5e is disengaged from the tip of the female screw 4d of the screw cylinder 4, and the screwing is released, and the screwing is restored by the relative rotation in the same direction, and the screwing of the first screwing part 8 is released. And screwing return is repeated.

  Here, a sliding resistance is generated between the piston 7 attached to the moving body 6 and the inner peripheral surface of the filling member 1, and this sliding resistance is caused by the biasing force of the spring portion 10 y of the rotating member 10. When the first screwing part 8 is screwed back, the resistance of the urging force of the spring part 10y acting on the moving body 6 via the second screwing part 9 becomes resistance, and in some cases, the spring part of the rotating member 10 Although there is a possibility that the first screwing portion 8 is not screwed back with an urging force of 10y, in the present embodiment, as described above, the movable body 6 can move by a predetermined amount in the axial direction with respect to the piston 7. Has been.

  That is, the moving body 6 is moved backward from the position shown in FIG. 11 via the second screwing portion 9 by the biasing force of the spring portion 10y of the rotating member 10 after the screwing of the first screwing portion 8 is released. 12, as shown in FIG. 12, it moves rearward with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1. The first screwing portion 8 is screwed back at the position where the tip surface of the groove 6d abuts the root of the annular protrusion 7b of the piston 7 on the tip side. When the moving screw cylinder 5 moves forward while the spring portion 10y of the rotating member 10 is compressed by the further relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction, it moves through the second screwing portion 9. The body 6 moves forward to the state shown in FIG. 11 and the screwing of the first screwing part 8 is released. In this way, the mobile body 6 is not subjected to sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1, and the mobile body 6 has a short axial range relative to the piston 7 (the annular groove portion of the mobile body 6). 6d) Going back and forth, the screw release and screw return of the first screwing part 8 are repeated, and the first screwing part 8 is screwed and returned smoothly and satisfactorily.

  Then, 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 filling member 1 and the main body cylinder 3 in the feeding 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 part 9 works, and only the moving body 6 moves forward as shown in FIG. When the moving body 6 alone moves forward, as described above, the moving body 6 is short in the predetermined axial direction by repeatedly releasing the screwing of the first screwing portion 8 and returning the screwing. Move forward and back repeatedly within the range.

  Here, in the 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 filling member 1 and the main body cylinder 3 in the feeding direction. Since the screw release and the 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 condition of the moving body 6 are suitably sensed by the user.

  And only the moving body 6 moves forward by the relative rotation accompanied by the click feeling in the feeding direction of the filling member 1 and the main body cylinder 3, and the filling material M is pushed out by the piston 7 at the tip and appears through the opening 1a.

  At this time, since the lead of the second screwing portion 9 is set to a small lead that moves forward by 0.5 mm with respect to one rotation, the moving body 6 is slowly drawn out according to the small lead of the second screwing portion 9. The filler M appears appropriately from the opening 1a of the filling member 1 and is put into use. That is, there is no possibility that the filler M is excessively discharged by mistake.

  In the case of using from the initial state, specifically, the case where the tip surface of the filler M is near the opening 1a at the tip of the filling member 1 and the moving screw cylinder 5 has not reached the forward limit. In this case, even if the moving screw cylinder 5 does not reach the forward limit, the filler M appears through the opening 1a.

Then, after use, when the filling member 1 and the main body cylinder 3 are relatively rotated in the retraction direction, the screwing protrusion 5e of the moving screw cylinder 5 biased rearward is the female thread 4d of the screw cylinder 4. When the first screwing portion 8 is screwed back and the relative rotation of the filling member 1 and the body tube 3 in the rewinding direction is further continued, the rotation preventing portion 60 and the rotation preventing portion 50 The screwing action of the first screwing part 8 and the second screwing part 9 is activated, the moving screw cylinder 5 is retracted, and the moving body 6 is also retracted with respect to the moving screw cylinder 5. That is, the moving body 6 is retracted along with the moving screw cylinder 5 and is also retracted alone.

  At this time, as described above, the lead of the first screwing portion 8 retreats by 8 mm with respect to one rotation of the filling member 1 and the main body cylinder 3, and the lead of the second screwing portion 9 is rotated once. On the other hand, since it is set to retreat by 0.5 mm, the moving screw cylinder 5 retreats large and quickly (8 mm for one rotation), and the moving body 6 itself retreats small and slowly (0.5 mm for one rotation). Accordingly, the moving body 6 moves backward by adding a small retracting amount of the moving body 6 itself to the large retracting amount of the moving screw cylinder 5 (8.5 mm for one rotation). That is, the moving body 6 is quickly retracted by the cooperative action of the first and second screwing portions 8 and 9.

  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 filler M comes into close contact with the inner peripheral surface of the filling member 1. 7 and the packing M are in close contact with each other, and as the piston 7 moves backward, a suction action (an action for maintaining the close contact) due to decompression acts between the piston 7 and the packing M, as shown in FIG. The filling material M is pulled back in the filling member 1 and retreats, and the filling material M quickly immerses from the opening 1a at the tip of the container. In particular, when the filler M is, for example, a soft, jelly-like, or mousse-like rod-like material, the rod-like material is likely to be in close contact with the filling member 1 and the piston 7, so that the above suction action works better.

  When the moving screw cylinder 5 is quickly retracted by the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction, the rear end surface of the spring portion 5a of the moving screw cylinder 5 comes into contact with the bottom surface of the main body cylinder 3. In accordance with the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction, the moving screw cylinder 5 moves backward while the spring portion 5a of the moving screw cylinder 5 is compressed and stores the urging force. The screwing protrusion 5e is disengaged from the rear end of the female screw 4d of the screw tube 4, and the screwing of the first screwing portion 8 is released.

  In this unscrewed state, the moving screw cylinder 5 is urged forward by the urging force of the spring portion 5a of the moving screw cylinder 5. Therefore, when the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction is further continued, the screwing projection 5e of the moving screw cylinder 5 biased forward becomes the female thread 4d in the screw cylinder 4. The first screwing part 8 is screwed and returned to the rear end adjacent to the rotation direction. Then, when the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction is further continued, the moving screw cylinder 5 moves backward while the spring portion 5a of the moving screw cylinder 5 is compressed, and the moving screw cylinder 5 The screwing protrusion 5e is released from the rear end of the female screw 4d of the screw tube 4, and the screwing is released, and the screwing is restored by relative rotation in the same direction. The screw release and screw return are repeated.

  At this time, the moving body 6 is urged forward from the screwing release position shown in FIG. 12 by the urging force of the spring part 5a of the moving screw cylinder 5 via the second screwing part 9, as shown in FIG. As shown, it moves forward with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1, and the flange portion 6 a of the moving body 6 moves to the cylindrical portion 7 d of the piston 7. The first screwing portion 8 is screwed back at a position where it abuts on the rear end surface 7f. When the moving screw cylinder 5 moves backward while the spring portion 5a of the moving screw cylinder 5 is compressed by the further relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction, the second screwing portion 9 is interposed. Thus, the moving body 6 moves backward to the state shown in FIG. 12, and the screwing of the first screwing portion 8 is released. As described above, the moving body 6 is short in the predetermined axial direction with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1 as in the case of forward movement. Back and forth within the range (annular groove 6d of the moving body 6), the first screwing portion 8 is repeatedly unscrewed and screwed back, and the first screwing portion 8 is smoothly and satisfactorily screwed back. It is supposed to be.

  Then, the screwing action of the first screwing part 8 works in this way, the moving screw cylinder 5 moves backward by a predetermined amount and reaches the retreat limit, and the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction is performed. In a state where the screw release and screw return of the first screwing portion 8 are repeated (the screwing action of the first screwing portion 8 is not substantially activated). Only the screwing action of the second screwing part 9 works, and only the moving body 6 moves backward as shown in FIG. Note that, when the moving body 6 alone is retracted, as described above, the moving body 6 is short in the predetermined axial direction by repeatedly releasing the screwing of the first screwing portion 8 and returning the screwing. Move back and forth repeatedly within the range.

  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 filling member 1 and the main body cylinder 3 in the retraction direction. Since the unscrewing and the screwing return 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 state of the moving body 6 are suitably detected by the user. .

  Then, when only the moving body 6 is retracted due to the relative rotation with a click feeling in the retraction direction between the filling member 1 and the main body cylinder 3, the lead of the second screwing portion 9 is 0 for one rotation. Since it is set to a small lead that retreats by 5 mm, the moving body 6 is slowly fed back according to the small lead of the second screwing portion 9, and the filler M is slowly pulled back along with the moving body 6. Therefore, it is possible to prevent the filler M from returning too much, and then finely adjust and return it.

  When the filling M is used from this state, the same operation as described above is performed, and such an operation is repeated.

  Moreover, as shown in FIG. 4, when the piston 7 moves forward to the maximum by the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction, the filling material M is almost used up.

  Thus, according to the filler extrusion container 100 of the present embodiment, the movable body 6 moves forward (retracts) by the screwing action of the first screwing portion 8 and the second screwing portion 9 in the fixed section, Since the moving body moves forward (retreats) only by the screwing action of the second screwing portion 9 beyond a certain section, the two-stage feeding / rewinding of the moving body 6 according to the setting with the speed changed is reliably performed. It is possible.

  In particular, in the present embodiment, in a certain section, the movable body 6 quickly moves forward by the cooperative action of the first and second screwing portions 8 and 9, and then only the second screwing portion 9 is screwed. Since it moves forward slowly by the combined action, it is prevented that the filler M is accidentally put out too much.

  Further, in the present embodiment, when the moving body 6 moves forward / backward in a certain section and the screwing of the first screwing part 8 is released, the first screwing part 8 is screwed back. Since the spring portion 10y of the rotating member 10 and the spring portion 5a of the moving screw cylinder 5 which are urging means for urging the first screwing portion 8 are released, the urging means is released. The first screwing portion 8 is screwed back by the urging force, and accordingly, the filling member 1 and the main body cylinder 3 are further rotated relative to each other, and the moving body 6 is screwed back to the first screwing portion 8. When moving forward / backward, the screwing action of the first screwing portion 8 works without any trouble so that the moving body 6 moves forward / backward. Further, the screwing of the first screwing part 8 is released, the filling member 1 and the main body cylinder 3 are further rotated relative to each other, and the moving body 6 advances / retreats in the direction in which the first screwing part 8 releases the screwing. In this case, the screw release of the first screwing portion 8 and the screwing return by the urging means are repeated, thereby generating a click feeling, and the degree of relative rotation and the moving condition of the moving body 6 are given to the user. It is to be perceived.

  In addition, the present embodiment has the following effects. That is, since the piston 7 is in close contact with the filling member 1, the filling M is in close contact with the filling member 1, and the filling M and the piston 7 are in close contact with each other in the filling member 1, While the filler M is pushed out as it moves forward and emerges from the opening 1a at the front end of the container, a suction action by decompression acts between the piston 7 and the filler M as the piston 7 moves backward, so that the filler M is inside the filling member 1. Thus, the filling material M can be fed out and fed back without any trouble.

  Further, when an external action is applied due to an impact, vibration, or the like, if the piston 7 and the filler M are separated from each other, the pressure is reduced, and the close contact action is exerted, so that the filler M is separated from the piston 7. The filling M is prevented from coming out of the container 100.

  Further, as described above, since the filler M is in close contact with the filling member 1 (particularly, the soft filler is in close contact with the filling member 1), even if the filler M is broken in the filling member 1. The broken portion is not detached from the filling member 1 and can be used continuously. Further, the close contact of the filling M with the inner wall of the filling member 1 also prevents the filling M from coming out of the container 100.

  In addition, it is possible to use a particularly soft rod-like material such as a jelly-like or mousse-like material that cannot be maintained by a normal rod-like material.

  In addition, when the inner peripheral surface of the filling member 1 is gradually tapered toward the tip side (tapered shape), a particularly soft rod-shaped object can be held and an external action such as impact or vibration is added during storage. This is preferable because the rod-shaped object is further prevented from falling off and is kept safe. Moreover, even if the opening 1a at the front end of the filling member 1 is narrower than the cylindrical hole on the rear side (the cylindrical hole of the filling member 1), the same operation and effect are obtained. And in the structure which narrows the opening 1a in this way, since the solidified filler M is pushed out by the piston 7 while narrowing the narrow opening 1a, the composition collapses and becomes soft, and the feeling of use is moderate. Moreover, it is possible to hold | maintain the filling material M which mix | blended the volatile component by giving airtightness to the fitting part of a cap.

  Furthermore, according to the present embodiment, the screwed portion of the filler extruding container 100 has a double spiral structure formed by the first and second screwed portions 8 and 9, so that the axial length of the container 100 can be saved. However, it is possible to ensure the length of the filler M.

  In the present embodiment, the lead of the first screwing portion 8 is advanced (retracted) by 8 mm with respect to one rotation of the relative rotation of the filling member 1 and the main body cylinder 3, and the lead of the second screwing portion 9 is set to one. By setting to advance (retreat) by 0.5 mm with respect to the rotation, the movable body 6 advances (retreats) by 8.5 mm with respect to one rotation in a certain section. It moves forward (retreats) by 0.5 mm, that is, as described above, it is possible to advance (retreat) quickly in a certain section and to advance (retreat) slowly after exceeding a certain section. You can also

  For example, the lead of the first screwing portion 8 is set to a backwardly moving screw that moves backward (advances) by 1 mm per rotation and the lead of the second screwing portion 9 moves forward (retreats) by 2 mm per rotation. As a result, the movable body 6 advances (retreats) by 1 mm with respect to one rotation in a certain section, and the movable body 6 advances (retreats) by 2 mm with respect to one rotation when the predetermined section is exceeded. It is possible to make an operation of moving forward (backward) quickly when the vehicle goes over a certain section. With such a configuration, when a large amount of the filling material M is fed out to check the filling material M, the filling material M can be quickly moved forward by quickly moving beyond a certain section, and the certain section can be used during use. By slowly retreating the filler M, the filler M can be used while being finely fed back, and after use, after the filler M has been finely returned by a small amount, it can be fed back at once.

  Further, for example, the lead of the first screwing portion 8 is advanced (retracted) by 3 mm with respect to one rotation, and the lead of the second screwing portion 9 is moved back (advanced) by 2 mm with respect to one rotation. With this setting, the movable body 6 moves forward (retreats) by 1 mm with respect to one rotation in a certain section, and when the predetermined section is exceeded, the moving body 6 moves backward (advances) by 2 mm with respect to one rotation. It can be set to move forward (backward) and quickly reverse (forward) when a certain section is exceeded. Further, for example, the lead of the first screwing portion 8 is advanced (retracted) by 4 mm with respect to one rotation, and the lead of the second screwing portion 9 is moved back (advanced) by 1 mm with respect to one rotation. By setting to, the moving body 6 moves forward (retreats) by 3 mm for one rotation in a certain section, and when exceeding a certain section, the moving body 6 moves back (advances) by 1 mm for one rotation. It can be set to move forward (backward) and slowly reverse (forward) when a certain section is exceeded. Further, for example, the lead of the first screwing portion 8 is advanced (retracted) by 2 mm per rotation, and the lead of the second screwing portion 9 is moved backward (advanced) by 1 mm per rotation. By setting to, the moving body 6 moves forward (retreats) by 1 mm with respect to one rotation in a certain section, and when exceeding a certain section, the moving body 6 moves back (advances) by 1 mm with respect to one rotation. (Backward), and when it exceeds a certain section, it can be operated to move backward (forward) at the same speed as the certain section. Thus, a special configuration in which the advancing / retreating direction of the moving body 6 is reversed by the relative rotation of the filling member 1 and the main body cylinder 3 in the same direction is also possible.

  In other words, according to the present embodiment, various combinations of various feeding and rewinding operations are possible, including reliable two-stage feeding / returning of the moving body 6 as set with different speeds. A filler extrusion container can be provided.

  The filling extrusion container 200 of the second embodiment is different from the filling extrusion container 100 of the first embodiment in that the moving screw shown in FIGS. 27 to 29 is used instead of the moving screw cylinder 5 shown in FIGS. This is a point using the cylinder 105. Further, as shown in FIG. 23, a rotating member 110 in which the shape of the rotating member 10 is slightly changed instead of the rotating member 10, a screw cylinder 104 in which the shape of the screw cylinder 4 is changed in place of the screw cylinder 4, and a piston Instead of 7, a piston 107 in which the shape of the piston 7 is slightly changed is used.

  27 to 29, the moving screw cylinder 105 is different from the moving screw cylinder 5 shown in FIGS. 13 to 15 in that the rear end of the outer diameter large diameter portion 5y is extended to the rear side, This is the point where the flange 5c is provided. The flange portion 5 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 flange portion 5 c of the moving screw cylinder 105. The other configurations are the same.

  As shown in FIG. 23, the rotating member 110 has a shape without the spring portion 10y of the rotating member 10 shown in FIGS. 16 and 17, and the other configurations are the same.

  The screw cylinder 104 has a shape in which the rear end of the screw cylinder 4 shown in FIGS. 18 and 19 extends rearward, and the other configurations are the same.

  The piston 107 has a bell shape in which the tip portion of the piston 7 shown in FIG. 10 is curved and protruded in an umbrella shape, and the other configurations are the same.

  23, the moving screw cylinder 105 is in the initial state of the filling extruding container 200 shown in FIG. 23, and its rear end surface comes into contact with the bottom surface of the main body cylinder 3, the spring portion 5a is compressed, and the screwing projection 5e is formed. The first screwing portion 8 is configured by being biased to the front side and the tip of the screwing projection 5e being screwed with the rear end of the female screw 4d of the screw cylinder 4.

  Then, when the moving screw cylinder 105 moves forward by a predetermined amount, as shown in FIG. 24, when the flange portion 5c comes into contact with the rear end surface of the screw cylinder 104 and is further relatively rotated in the feeding direction, the spring portion of the moving screw cylinder 105 The moving screw cylinder 105 moves forward while 5a is stretched and accumulates the urging force, and the screw projection 5e of the moving screw cylinder 105 is disengaged from the tip of the female screw 4d of the screw cylinder 104, and the first screwing portion 8 is screwed. Is released, and the first screwing portion 8 is screwed back by the urging force of the spring portion 5a of the moving screw cylinder 105 in accordance with the relative rotation in the further feeding direction, and this screwing release and screwing return are repeated. In this state, the moving body 6 moves back and forth within a short range in the predetermined axial direction with respect to the piston 107 without receiving sliding resistance between the piston 107 and the inner peripheral surface of the filling member 1. When the relative rotation is performed in the direction, only the screwing action of the second screwing part 9 works while the screwing release and screwing return of the first screwing part 8 are repeated, and only the moving body 6 Advances slowly with a click feeling, and the filler M is appropriately pushed out by the piston 107 at the tip, appears through the opening 1a, and is put into use. Accordingly, there is no possibility that the filler M is excessively discharged by mistake.

  Then, after use, when the filling member 1 and the main body cylinder 3 are relatively rotated in the retraction direction, the first screwing part 8 is screwed back by the spring part 5a of the moving screw cylinder 105, and further the same. By the relative rotation in the direction, the screwing action of the first screwing portion 8 and the second screwing portion 9 is activated, the moving screw cylinder 105 is quickly retracted, and the moving body 6 is moved relative to the moving screw cylinder 105. Accordingly, the movable body 6 is quickly retracted by the cooperative action of the first and second screwing portions 8 and 9, and the packing M is contained in the filling member 1 by the suction action by the decompression following the backward movement of the piston 107. It is pulled back and quickly retracts (see FIG. 25).

  Then, when the moving screw cylinder 105 moves backward due to 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 3 and is further rotated in the same direction as in the initial state. Then, while the spring portion 5a of the moving screw cylinder 105 is compressed and accumulates the urging force, the moving screw cylinder 105 moves backward, and the screwing projection 5e of the moving screw cylinder 105 is disengaged from the tip of the female screw 4d of the screw cylinder 4. The screwing of the first screwing part 8 is released, and the first screwing part 8 is screwed back by the urging force of the spring part 5a of the moving screw cylinder 105 according to the relative rotation in the further rewinding direction. The screw release and screw return are repeated. In this state, the moving body 6 moves back and forth within a short range in the predetermined axial direction with respect to the piston 107 without receiving sliding resistance between the piston 107 and the inner peripheral surface of the filling member 1. When the relative rotation is performed in the direction, only the screwing action of the second screwing part 9 works while the screwing release and screwing return of the first screwing part 8 are repeated, and only the moving body 6 Slowly retreats with a click.

  In addition, as shown in FIG. 26, when the piston 107 moves forward to the maximum by the relative rotation of the filling member 1 and the main body cylinder 3 in the feed-out direction, the filling material M is almost used up.

  As another example of the assembly procedure of the main assembly 240, the moving screw cylinder 205 is screwed into the moving body 6 to the end to obtain the moving body assembly, and then the moving body assembly is the same as described above. The movable cylinder 6 is inserted from the opening side of the main body cylinder 202 of the operation cylinder assembly, and the movable body 6 is externally engaged with the shaft body 203y of the operation cylinder 203, and the movable screw cylinder 205 is inserted into the main body cylinder 202. While urging the tip of the spring part 205b of the moving screw cylinder 205 in a direction against the urging force of the spring part 205b by a cylindrical jig, the operation cylinder 203 is temporarily rotated in the feeding direction, By rotating in the extending direction, the screwing action of the second screwing part 209 is exerted, and the moving body 6 is moved forward with respect to the moving screw cylinder 205 in cooperation with the rotation preventing part 250 of the moving body 6. Movement of moving body 6 in the same direction as Ensuring min, then rotated until it stops rotating in the feed-back direction of the operation tube 203, may be obtained the main body side assembly 240.

  On the other hand, in the filling member 201, the discharge port 201 c is closed with the seal 212, and the filling region 201 q is filled with a predetermined amount of the filling material L and there is no space in the tip of the filling member 201. And Then, with respect to the filling member 201 filled with the filling L, the front end side of the main body side assembly 240 is extrapolated from above, and the filling member 201 is inserted into the main body cylinder 202 while inserting the piston 107 into the filling member 201. Installing.

  At this time, the inner circumferential surface of the filling member 201 is engaged with the main body cylinder 202 while being in sliding contact with the annular protrusion 7 c for ensuring the watertightness of the piston 107. At the time of this engagement, as shown in FIG. 30, the air vent groove 201i on the inner peripheral surface of the filling member 201 is positioned so as to cross the annular protrusion 7c of the piston 107 in the axial direction. The air on the filling side is extracted to the rear side through 201i.

  When the mounting of the filling member 201 is completed, as shown in FIG. 30, there is a slight space A between the filling material L filled in the filling member 201 and the piston 107 inserted into the filling member 201. It is left. Here, the space A is formed on the front side of the entire surface of the piston 107. Such a space A is formed because the filling member 201 filled with the filling material L is assembled to the main assembly 240 and the piston 107 is inserted into the filling member 201. This is because if the gap between the first and second members 107 is set to zero, the filler L may be pushed out by the piston 107 and appear from the filling member 201. In this embodiment, in order to avoid this, a space is used. A is provided.

  Finally, if the seal 212 is peeled off, an initial state of the filler extruding container 300 shown in FIG. 30 is obtained.

  In this state, the piston 107 is in close contact with the inner peripheral surface of the filling member 201, and the filler L is in close contact with the inner peripheral surface of the filling member 201.

  According to the filling material extruding container 300 configured as described above, as shown in FIG. 50, the filling member 201 filled with the filling material L is inserted and attached to the front end side of the main assembly 240. Therefore, the assembly after filling the filling material 201 into the filling member 201 is easy.

  In the initial state of the filling extrusion container 300 shown in FIG. 30, when the cap 210 is removed by the user and the main body cylinder 202 and the operation cylinder 203 are relatively rotated in the feeding direction, the first screw is pushed. The screwing action of the joint part 208 is activated, and the moving screw cylinder 205 advances quickly by cooperation with the rotation preventing part 260 of the moving screw cylinder 205, and at the same time, the screwing action of the second screwing part 209 is performed. Is operated, and the moving body 6 slowly moves forward with respect to the moving screw cylinder 205 by the cooperation with the rotation preventing portion 250 of the moving body 6, so that the moving body 6 is moved to the first and second screwing portions 208. 209 move forward quickly.

  Then, from the initial state shown in FIG. 30, that is, the state where the air vent groove 201 i is opened to release the air in the space A, when the piston 107 quickly moves forward by a predetermined amount while sliding inside the filling member 201, As shown in FIG. 31, the air escapes well rearward through the air vent groove 201 i, and the space A is immediately lost, the air vent groove 201 i is closed, and the piston 107 and the filler L are connected to the filler member 201. It is in a state of airtight contact inside.

  Thus, since the piston 107 moves forward quickly, the pre-rotation for escaping the air in the space A can be reduced. If the space A remains, the piston 107 moves forward and compresses the air, which may cause a delay in the appearance of the filling L from the tip. However, in the present embodiment, as described above, the piston 107 The space A is immediately lost by the advance.

  Then, when the moving screw cylinder 205 is quickly advanced by a predetermined amount in this way, as shown in FIG. 31, when the flange portion 205g of the spring portion 205b comes into contact with the rear end surface of the filling member 201 and is further relatively rotated in the feeding direction. While the compression spring 205f of the moving screw cylinder 205 is compressed and accumulates the urging force, the moving screw cylinder 205 moves forward, and the screwing projection 205e of the moving screw cylinder 205 is disengaged from the tip of the female screw 204d of the screw cylinder 204. The first screwing portion 208 is screwed back by the urging force of the compression spring 205f of the moving screw cylinder 205 in accordance with the relative rotation in the further feeding direction, and the screwing release of the first screwing portion 208 is released. And screwing return is repeated. In this state, the moving body 6 moves back and forth within a short range in the predetermined axial direction with respect to the piston 107 without receiving sliding resistance between the piston 107 and the inner peripheral surface of the filling member 201. When the relative rotation is performed in the direction, only the screwing action of the second screwing portion 209 works in the state where the screwing release and screwing return of the first screwing portion 208 are repeated, and only the moving body 6 32 slowly moves forward with a click feeling, and as shown in FIG. 32, the filler L is appropriately pushed out by the piston 107 at the tip, appears through the discharge port 201c, and is put into use. Therefore, there is no possibility that the filling L is excessively discharged by mistake.

  Further, as described above, due to the rapid advancement of the moving screw cylinder 205, the space A is eliminated as shown in FIG. 31, and the filling region 201q between the inside of the front end of the filling member 201 and the piston 107 is filled. Since the object L is filled without a gap, the filler L is immediately discharged from the discharge port 201c by the advancement of only the moving body 6.

  Then, after use, when the main body cylinder 202 and the operation cylinder 203 are relatively rotated in the retraction direction, the first screwing portion 208 is screwed back by the compression spring 205f of the moving screw cylinder 205, and further the same. Due to the relative rotation in the direction, the screwing action of the first screwing part 208 is activated, and the moving screw cylinder 205 is quickly retracted by the cooperation with the rotation preventing part 260 of the moving screw cylinder 205, The screwing action of the second screwing portion 209 is activated, and the moving body 6 is slowly retracted with respect to the moving screw cylinder 205 by the cooperation with the rotation preventing portion 250 of the moving body 6. The first and second screwing portions 208 and 209 are quickly retracted by the cooperative action.

  At this time, as shown in FIG. 33, the filling L is pulled back from the discharge port 201c of the filling member 201 by the suction action by the decompression following the retraction of the piston 107, and quickly moves back to the inside of the discharge port 201c of the filling member 201. A predetermined space B is immediately formed. Therefore, the filling L remaining on the outer surface 201a at the front end of the filling member 201 is reduced, which is economical.

  Then, when the moving screw cylinder 205 moves backward due to further relative rotation in the same direction, the flange part 205g of the spring part 205b of the moving screw cylinder 205 comes into contact with the front end surface of the convex part constituting the knurl 202a of the main body cylinder 202, When the rotation is further rotated in the rewinding direction, the compression spring 205f of the moving screw cylinder 205 is stretched and accumulates the urging force, while the moving screw cylinder 205 is retracted and the screwing projection 205e of the moving screw cylinder 205 is moved to the screw cylinder 204. The first screwing portion 208 is disengaged from the rear end of the female screw 204d, the screwing of the first screwing portion 208 is released, and the first screwing is performed by the biasing force of the compression spring 205f of the moving screw cylinder 205 in accordance with the relative rotation in the further retraction direction. The part 208 is screwed back, and this screwing release and screwing return are repeated. In this state, the moving body 6 moves back and forth within a short range in the predetermined axial direction with respect to the piston 107 without receiving sliding resistance between the piston 107 and the inner peripheral surface of the filling member 201. When the relative rotation in the direction is performed, only the screwing action of the second screwing portion 209 is performed as shown in FIG. 34 in the state where the screwing release and screwing return of the first screwing portion 208 are repeated. And only the moving body 6 slowly moves backward with a click feeling.

  Then, when the movable body 6 at an arbitrary position advanced by the relative rotation of the main body cylinder 202 and the operation cylinder 203 in the retraction direction is retracted, the filling material filled in the filling region 201q Even if the air mixed in L and the filling L expands due to a change in temperature or pressure, leakage of the filling L from the discharge port 201c by the predetermined space B provided inside the discharge port 201c. Is prevented.

  In this state, that is, when the moving screw cylinder 205 and the moving body 6 are retreated, when the user again rotates the main body cylinder 202 and the operation cylinder 203 relative to each other in the extending direction so as to make the filling L into a use state. As described above, the screwing action of the first screwing portion 208 is activated, and the moving screw cylinder 205 is quickly advanced by the cooperation with the rotation preventing portion 260 of the moving screw cylinder 205, and the second The screwing action of the screwing portion 209 is activated, and the moving body 6 slowly moves forward with respect to the moving screw cylinder 205 by the cooperation with the rotation preventing portion 250 of the moving body 6. The first and second screwing portions 208 and 209 move forward quickly by the cooperative action.

  Thus, since the piston 107 moves forward quickly, pre-rotation for escaping the air in the space B can be reduced.

  Then, as shown in FIG. 35, when the piston 107 moves forward to the maximum by the relative rotation of the main body cylinder 202 and the operation cylinder 203 in the extending direction, the bell-shaped piston 107 is placed on the inner surface 201b of the front end portion of the filling member 201. In contact with each other, the filler L in the filling region 201q is almost used up.

  Thus, according to the filler extrusion container 300 of the present embodiment, it is needless to say that substantially the same effect as that of the first embodiment can be obtained, and in addition, the air in the spaces A and B is released. Therefore, the effect of reducing the pre-rotation can be obtained.

  In addition, by making the filling member 201 transparent, as shown in FIG. 30, the color of the filling material L can be confirmed through the flange portion 201d of the filling member 201 with the cap 210 at the tip.

  Incidentally, in order to release the air in the space A, the relative rotation operation between the main body cylinder 202 and the operation cylinder 203 that moves the piston 107 forward by a predetermined amount to eliminate the space A may be performed after purchase by the user as described above. It is also possible to carry out at the factory after the assembly of the filler extrusion container 300.

  As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. For example, the moving mechanism of the moving body 6 of the first and second embodiments may be applied to the third embodiment, and the moving mechanism of the moving body 6 of the third embodiment is the first and second embodiments.

  In addition, the male screw and the female screw may function in the same manner as a screw thread, such as an intermittently arranged projection group or a spiral and intermittently arranged projection group. The mating protrusion may be a continuous screw thread.
