  In addition, a pair of arc-shaped ridges extending a predetermined length along the circumferential direction is provided on the outer peripheral surface of the housing member 1 at a rear side near the flange portion 1d. A pair of concavo-convex portions 1f are opposed to each other on the front side, and are provided to engage with the annular convex recess 2b of the main body cylinder 2 in the axial direction. In addition, at a position that is equidistant in the circumferential direction at a position on the rear side of the uneven portion 1 f on the outer peripheral surface of the housing member 1, an axially extending protrusion 1 g is rotated in the first half of the knurled 2 a of the main body cylinder 2. It is provided to be engaged with. Furthermore, as shown in FIG. 36, an air vent groove 1 i that is open to the rear side and is short toward the front end side is provided on the inner peripheral surface of the rear end portion of the housing member 1.

  The housing member 1 is inserted from the rear end side to the front end side of the main body cylinder 2, and as shown in FIG. 1f engages with the annular convex recess 2b of the main body cylinder 2 in the axial direction, and the protrusion 1g engages with the front half of the knurling 2a of the main body cylinder 2 in the rotational direction, so that the main body cylinder 2 rotates synchronously. The main body cylinder 2 is integrated with the main body cylinder 2 so that it can be detached in the axial direction. In this state, as shown in FIG. 2, the annular projecting portion 7 g of the piston 7 contacts the inner peripheral surface of the rear end portion of the housing member 1. As shown in FIG. 1, a cap 10 is detachably attached to the housing member 1.

  In the content extruding container 100 configured as described above, the elastic body 12 is pressed against the inclined inner surface 1b of the distal end portion of the housing member 1 when the movable body 6 is advanced forward (see FIG. 11), dimensions, arrangement, etc. are set.

  Next, an example of an assembly procedure of the content extruding container 100 having such a configuration will be described with reference to FIG. First, the intermediate member 13 is screwed into the moving body 6 to the end, and then the locking member 11 is inserted into the gap between the moving body 6 and the intermediate member 13 and attached to the rear end portion of the moving body 6 ( (See FIG. 28). At this time, the locking member 11 enters the slit 6e of the moving body 6 and engages in the rotational direction and the axial direction while the protrusion 11a is bent radially outward by the slit 11b sandwiching the protrusion 11a. Thus, by making the moving body 6 and the locking member 11 as separate parts, the intermediate member 13 can be screwed from the rear side of the moving body 6.

  Next, the moving body 6 and the locking member 5 are connected while the locking projection 6 d of the moving body 6 is caused to enter the groove 5 d of the locking member 5. At this time, the locking projection 6d of the moving body 6 abuts on the locking projection 5e provided in the groove 5d of the detent member 5, but the front surface of the locking projection 5e is an inclined surface. Therefore, it easily enters backward (see FIG. 21). Next, the distal end portion of the intermediate member 13 to which the movable body 6 and the rotation preventing member 5 are assembled is screwed to a predetermined position of the screw cylinder 4, and then a piston 7 is attached to the distal end of the movable body 6. The elastic body 12 is attached and a temporary assembly is obtained.

  Next, this temporary assembly is inserted from the front end side of the main body cylinder 2, and the screw cylinder 4 is moved while engaging the protrusion 4 a of the screw cylinder 4 constituting the temporary assembly with the knurl 2 a of the main body cylinder 2 in the rotation direction. The main body cylinder 2 is mounted, and then the operation cylinder 3 is inserted from the rear end side of the main body cylinder 2, and the protrusion 5 c of the rotation prevention member 5 constituting the temporary assembly is inserted into the knurling 3 c of the operation cylinder 3 in the rotation direction. The main body cylinder 2 and the operation cylinder 3 are connected while being engaged with each other, and the main body side assembly 40 is obtained.

  On the other hand, in the housing member 1, in a state where the discharge port 1 c is closed with the seal 12 and inverted, the housing region 1 x is filled with a predetermined amount of contents L so that there is no space in the tip of the housing member 1. . And the front end side of the main assembly side assembly 40 is extrapolated from above to the accommodating member 1 accommodating the contents L, and the accommodating member 1 is attached to the main body cylinder 2.

  At this time, the inner circumferential surface of the housing member 1 is engaged with the main body cylinder 2 while being in sliding contact with the annular protrusion 7g for ensuring the watertightness of the piston 7, as shown in FIG. At the time of this engagement, the air vent groove 1i on the inner peripheral surface of the housing member 1 shown in FIG. 36 is positioned so as to cross the annular protrusion 7g of the piston 7 in the axial direction. The air on the object side is extracted well to the rear side. And finally, if the seal | sticker 12 is peeled, the content extrusion container 100 of the initial state shown in FIG. 1 will be obtained. The seal 12 is hygienic when peeled off after purchase by a user (consumer).

  According to the content extruding container 100 configured as described above, as shown in FIG. 37, the storage member 1 that stores the content L is inserted and attached to the front end side of the main assembly 40. Therefore, the contents L can be easily assembled after being accommodated in the accommodating member 1, and the contents L are accommodated in the accommodating area 1 x between the inner side of the distal end of the accommodating member 1 and the elastic body 12 of the main assembly 40. Is fully (full) filled.

  In addition, since the rotation prevention member 5 that functions as a rotation stopper for the moving body 6 is accommodated in the main assembly 40, there is no need to make the accommodation member 1 and the movement body 6 non-circular as a rotation prevention, and therefore, the circular shape. Therefore, alignment in the rotational direction when connecting the housing member 1 and the main assembly 40 is not necessary, and the manufacture is facilitated.

  And when a user uses, with respect to the content extrusion container 100 of the initial state shown in FIG. 1, the cap 10 is removed by the user, and a container front part (the main body cylinder 2; the accommodating member 1 also). Yes) and the rear part of the container (the operation cylinder 3) are relatively rotated in the feeding direction which is one direction.

  Here, when the container front part and the container rear part are relatively rotated in the feeding direction, when the screwing action of the first screwing part 8 is activated first, the screwing action of the second screwing part 9 is When operating first, the screwing action of the first and second screwing portions 8 and 9 may operate together. First, a case where the screwing action of the first screwing portion 8 is activated first will be described.

  When the first screwing portion 8 constituted by the male screw 6b of the moving body 6 and the female screw 13a of the intermediate member 13 is actuated first, the rotation preventing member that engages with the operation cylinder 3 so as to be synchronously rotatable. The moving body 6 moves forward from the initial position shown in FIG. 1 in cooperation with the rotation stopper 50 of the moving body 6 constituted by the groove portion 5d of 5 and the locking projection 6d of the moving body 6.

  As shown in FIG. 4, the movable body 6 moves forward by a predetermined amount, and the locking member 11 that is attached to the movable body 6 and constitutes the rear end limit of the male screw 6 b of the movable body 6 is the female member of the intermediate member 13. When reaching the rear end of the screw 13a, the screwing action of the first screwing portion 8 stops.

  When the container front portion and the container rear portion are continuously rotated relative to each other in the feeding direction, the screwing action of the first screwing part 8 is stopped, so that the screwing action of the second screwing part 9 works. The intermediate member 13 moves forward with the moving body 6 as shown in FIG.

  Subsequently, when the container front portion and the container rear portion are relatively rotated in the feeding direction, and the intermediate member 13 and the moving body 6 move forward by a predetermined amount, the locking protrusion 6d of the moving body 6 becomes the locking protrusion 5e of the rotation preventing member 5. When the container front portion and the container rear portion are rotated relative to each other in the feeding direction, the engagement protrusion 6d of the movable body 6 and the rotation preventing member 5 are engaged as shown in FIG. Due to the locking with the stop protrusion 5e, the moving body 6 moves forward with the rotation preventing member 5, and the moving body 6, the intermediate member 13 and the rotation preventing member 5 move forward.

  Further, in the initial state shown in FIG. 1, the container front portion and the container rear portion are relatively rotated in the feeding direction, and the second screwing portion 9 configured by the female screw 4 c of the screw cylinder 4 and the male screw 13 b of the intermediate member 13. In the case where the screwing action is activated first, the intermediate member 13 is shown in FIG. 1 as shown in FIG. 1 by the cooperation of the screwing action of the second screwing part 9 and the rotation preventing part 50. It moves forward with the moving body 6 from the position in the initial state.

  Then, when the intermediate member 13 moves forward by a predetermined amount and the cylindrical portion 13c constituting the rear end limit of the male screw 13b of the intermediate member 13 reaches the rear end of the female screw 4c of the screw cylinder 4, the second threaded portion The screwing action 9 stops.

  When the container front portion and the container rear portion are continuously rotated relative to each other in the feeding direction, the screwing action of the second screwing part 9 is stopped, so that the screwing action of the first screwing part 8 works. As shown in FIG. 8, the movable body 6 moves forward by cooperation with the rotation stopper 50.

  Subsequently, when the container front portion and the container rear portion are relatively rotated in the feed-out direction and the moving body 6 advances by a predetermined amount, the locking projection 6d of the moving body 6 moves the locking projection 5e of the detent member 5 in the axial direction. Lock.

  Subsequently, when the container front portion and the container rear portion are relatively rotated in the feeding direction and the moving body 6 moves forward, the locking protrusion 6d of the moving body 6 and the locking protrusion 5e of the rotation preventing member 5 are locked. As shown in FIG. 9, the moving body 6 moves forward with the detent member 5.

  Further, in the initial state shown in FIG. 1, when the container front part and the container rear part are relatively rotated in the feeding direction, and the screwing action of the first screwing part 8 and the second screwing part 9 is operated together, The moving body 6 and the intermediate member 13 move forward from the initial position shown in FIG. 1 by the cooperation of the screwing action of the first and second screwing parts 8 and 9 and the rotation preventing part 50.

  Then, the moving body 6 and the intermediate member 13 move forward by a predetermined amount, and the locking protrusion 6d of the moving body 6 locks the locking protrusion 5e of the rotation preventing member 5 in the axial direction, followed by the container front and the container. When the rear part is relatively rotated in the feed-out direction, the movable body 6 moves forward with the detent member 5 by the latching of the latching projection 6d of the movable body 6 and the latching projection 5e of the detent member 5. The moving body 6, the intermediate member 13, and the rotation preventing member 5 move forward.

  Here, when the screwing action of the first screwing part 8 is actuated first, when the screwing action of the second screwing part 9 is actuated first, the first and second screwing parts 8, As shown in FIG. 1, the content L is stored in the housing member 1 in any case where the screwing action 9 is operated together (hereinafter, the operation order of the screwing action is referred to as any case). Since the accommodation region 1x between the inside of the tip of the container and the elastic body 12 is sufficiently filled, the content L is quickly and immediately without repeating the relative rotation more than necessary. It is discharged from 1c (see FIG. 11).

  Then, after the use, when the container front part and the container rear part are rotated relative to each other in the rewinding direction which is the other direction, if the screwing action of the first screwing part 8 operates first, When the moving body 6 moves backward by cooperation with the stopper 50 and the screwing action of the second screwing part 9 is activated first by relative rotation in the retraction direction, the rotation stopper 50, the intermediate member 13 moves backward with the moving body 6, and the screwing action of the first and second screwing portions 8, 9 is activated by relative rotation in the rewinding direction. When doing so, the movable body 6 and the intermediate member 13 are retracted by cooperation with the rotation stopper 50.

  As described above, regardless of the operation order of the screwing action, the contents L are sucked into the accommodation area 1x from the discharge port 1c of the accommodation member 1 by the retraction of the elastic body 12 accompanying the retraction of the movable body 6. In addition, a predetermined space is formed on the inner side of the discharge port 1 c of the housing member 1. Therefore, the contents L remaining on the outer surface 1a of the distal end portion of the containing member 1 are reduced and economical, and the contents L accommodated in the containing area 1x and the air mixed in the contents L are subjected to temperature changes and Even if it expands due to a change in atmospheric pressure, leakage of the contents L from the discharge port 1c is prevented by the predetermined space provided inside the discharge port 1c.

  Further, regardless of the operation order of the screwing action, the click engagement portion 4d of the screw cylinder 4 is configured in accordance with the relative rotation of the container front portion and the container rear portion in the feeding direction / returning direction. Since the protrusion 4e repeats the click engagement that enters the recess between the chevron portions 3e, 3e constituting the click engagement portion 3d of the operation cylinder 3, the user is given an appropriate click feeling and the feeding direction. / The degree of relative rotation in the retraction direction and the degree of movement of the moving body 6 are perceived by the user.

  For this reason, when the container front part and the container rear part are relatively rotated in the feeding direction (when the moving body 6 moves forward), an appropriate amount of the content L is discharged, and the container front part and the container rear part are fed back in the feeding direction. When the relative rotation is performed (when the movable body 6 moves backward), it is possible to prevent the elastic body 12 from returning too much and prevent the contents L from appearing from the discharge port 1c during the next use. ing.

  When the contents L remain in the accommodation area 1x, the container front portion and the container rear portion are relatively rotated again in the feeding direction by the user so that the contents L can be put into use. The operation is similar to the above, and such an operation is repeated.

  When the container front portion and the container rear portion are relatively rotated in the retraction direction and the screwing action of the first and second screwing portions 8 and 9 is stopped together, the movable body 6, The intermediate member 13 and the rotation preventing member 5 are returned to the initial position shown in FIG.

  Then, from the state shown in FIG. 6, when the container front part and the container rear part are relatively rotated in the feeding direction, the intermediate member 13 moves forward with the moving body 6 by the screwing action of the second screwing part 9, The moving body 6 moves forward with the rotation preventing member 5, and the moving body 6, the intermediate member 13 and the rotation preventing member 5 move forward. When the container front part and the container rear part are rotated relative to each other in the feeding direction, the cylindrical part 13c constituting the rear end limit of the male screw 13b of the intermediate member 13 becomes a screw cylinder as shown in FIGS. 4 reaches the rear end of the female screw 4c, the screwing action of the second screwing portion 9 stops, and the movable body 6, the intermediate member 13 and the rotation preventing member 5 reach the forward limit as shown in FIG. .

  Further, from the state shown in FIG. 9, when the container front part and the container rear part are relatively rotated in the feed-out direction, the moving body 6 moves forward with the detent member 5 by the screwing action of the first screwing part 8. To do. Subsequently, when the container front and the container rear are relatively rotated in the feed-out direction, the rear end limit of the male screw 6b of the moving body 6 is configured as shown in FIGS. The locking member 11 reaches the rear end of the female screw 13a of the intermediate member 13, and the screwing action of the first screwing portion 8 is stopped. As shown in FIG. The stop member 5 reaches the forward limit.

  Further, from the state shown in FIG. 10, when the container front part and the container rear part are relatively rotated in the feeding direction, when the screwing action of the first screwing part 8 is activated first, the moving body 6 is In the case where the second screwing portion 9 is actuated first, the intermediate member 13 moves forward with the moving body 6, and the first and second screwing portions 8 are moved forward. , 9 actuate together, the movable body 6 and the intermediate member 13 move forward. When the container front portion and the container rear portion are continuously rotated relative to each other in the feeding direction, the movable body 6, the intermediate member 13 and the rotation preventing member 5 reach the forward limit as shown in FIGS.

  Thus, in the content extruding container 100 of the present embodiment, the moving body 6, the intermediate member 13 and the rotation preventing member 5 move forward regardless of the operation order of the screwing action. It is configured to reach the forward limit.

  When the moving body 6, the intermediate member 13, and the rotation preventing member 5 reach the forward limit regardless of the operation order of the screwing action, as shown in FIG. 1 abuts against the inner surface 1b of the tip portion and elastically deforms following the inner surface 1b. At this time, the elastic body 12 is more preferably elastically deformed by the space 12 c in the elastic body 12. Due to such elastic deformation of the elastic body 12, there is almost no remaining content L remaining in a substantially distorted (obliquely cylindrical) space (a space including an inclined surface in the tip of the container) that cannot be pushed out by a conventional piston. It is sufficiently extruded and consumed, and it is economical because the contents L are hardly left over.

  In the present embodiment, when the screwing action of the second screwing part 9 is actuated after the screwing action of the first screwing part 8 is first actuated and stopped at the rear end limit 11, or , The case where the screwing action of the first screwing part 8 is actuated after the screwing action of the second screwing part 9 is actuated first and stopped at the rear end limit 13c is described. The screwing action of the next screwing part may be activated before stopping at the limits 11 and 13c. This occurs due to a balance of frictional resistance of the screwed portion.

  As described above, according to the content extruding container 100 of the present embodiment, when the container front part and the container rear part relatively rotatable to the container front part are relatively rotated, the first and second The screwing action of the screwing parts 8 and 9 works to engage the rear part of the container and the movable body 6 so as to be able to rotate synchronously, and to prevent the movable body 6 from engaging with the movable body 6 so as to be movable in the axial direction. By the cooperation with the member 5, the moving body 6 moves in the axial direction with respect to the front part of the container, and the rotation preventing member 5 is engaged with the rear part of the container so as to be movable in the axial direction. Since the structure moves in the axial direction, the moving distance of the moving body 6 can be extended as compared with the case where the detent of the moving body does not move in the axial direction, and the amount of use of the contents L can be increased. (The total length of the container is such that the detent of the moving body does not move in the axial direction. Flip has become possible to increase the accommodating capacity as the hiss the contents).

  The present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the operation tube 3 and the screw tube 4 are disposed in front of the container. Although it has composition which has click engagement part 34 (3d, 4d) which carries out click engagement according to relative rotation of a part and a container rear part, it can replace with this click engagement part 34, and can also use a ratchet mechanism. In this case, the chevron 3e and the protrusion 4e constituting the click engaging part 34 are controlled to rotate relative to each other in the retraction direction between the container front part and the container rear part, and the container front part and the container rear part are fed out. What is necessary is just to make it the structure like the ratchet tooth of the shape which accept | permits only the relative rotation to a direction.

  Moreover, in the said embodiment, although the outer surface 1a of the front-end | tip part of the accommodating member 1 is used as the application part, porous materials, such as foaming urethane and a fine net-like material, are used for the front-end | tip part (outer surface) 1a of the accommodating member 1, for example. It may be used as an application part, or it may be provided with fine hairs on the outer surface 1a as an application part, or a brush formed by bundling tapered taper polyester fibers is attached and this is used as an application part. Moreover, it is good also considering elastic bodies, such as a silicone rubber and a thermoplastic elastomer, as an application part. In addition, the housing member 1 is molded with two kinds of different materials of soft material by using a two-color different material injection molding machine to mold the transparent material hard part of the base and the part touching the skin, and adopting the one having excellent usability. Can do.

  Moreover, in the said embodiment, when the content L is made into semi-solid or soft solids, such as liquid form, jelly form, gel form, paste form, etc., for example, it is a particularly suitable content extrusion. Although the container 100 has been described, the contents are, for example, various rod-shaped cosmetics such as an eyeliner, eyebrow, lip liner, lipstick, etc., and a rod-shaped body such as a rod-shaped core such as a writing instrument. It can also be applied to. In this case, the accommodating member is a cylindrical body such as a pipe, and the rod-shaped body is accommodated in the cylindrical body, and the rod-shaped body follows the relative rotation in the feeding direction between the container front part and the container rear part. The moving body is pushed out by advancing in the axial direction and appears from the opening at the tip of the cylindrical body. When the contents are made into a rod-like body in this way, for example, a configuration in which the rod-like body and the piston at the tip of the moving body are brought into airtight contact in the cylindrical body is adopted, and the container front part and the container rear part are It is preferable to adopt a configuration in which the rod-shaped body moves backward as the moving body moves backward when it is relatively rotated in the retraction direction.

  Moreover, in the said embodiment, when the moving body 6 advances, the locking protrusion 5e is provided in order to lock the detent | locking member 5 to an axial direction reliably, For example, a user turns a container upside down, for example. For example, the rotation preventing member 5 can be moved by its own weight, or can be moved by friction or screwing.

  Further, in the above-described embodiment, the male screw and the female screw may function in the same manner as the screw thread, such as a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently. good.
