In the applying filler extruding container 100, if the main body tube 2 or the filling member 1 and the operating tube 3 are relatively rotated by a user, the movable body 6 moves forward and backward by the engaging mechanism and the rotation preventing mechanism mentioned above, and the leading end portion 3f of the protrusion 3e in the operating tube 3 constituting the click mechanism 11 mentioned above and the click tooth 12a of the click spring member 12 energized to the leading end portion 3f repeat the click engagement in accordance with the relative rotation at this time. Accordingly, the click feeling is given to the user, and a forward moving degree and a returning degree of the movable body 6 are detected on the basis of the click feeling.
Further, if the user relatively rotates the main body tube 2 or the filling member 1 and the operating tube 3 so as to move the movable body 6 forward while accompanying with the click feeling, at the first applying time after buying the applying filler extruding container 100, the applying filler L is rapidly (immediately) discharged from the discharge port 10c of the applying body 10 as shown in FIG. 19(a) without repeating the relative rotation more than necessary, because the applying filler L is sufficiently filled in the filling region 1x between the inner side of the discharge port 10c of the applying body 10 constituting the leading end portion of the filling member 1 and the elastic body 9 of the movable body 6 of the main body side assembly 40, as mentioned above. Accordingly, there is provided the applying filler extruding container 100 in which customer satisfaction is improved.
The user presses the applying portion 10a of the applying body 10 to the applied portion A so as to apply the applying filler L to the applied portion A in this state, as shown in FIG. 19(b). At this time, the applying portion 10a of the applying body 10 is elastically deformed so as to be concaved (collapsed) to the rear side on the basis of the pressing to the applied portion A. Since the applying portion 10a of the applying body 10 is elastically deformed as mentioned above, a feeling given to the applied portion A such as a skin or the like is soft and good. Further, since the applying portion 10a of the applying body 10 is pressed and collapsed, an internal pressure is increased, the applying filler L is discharged at a proper amount, and a use amount is secured.
Further, if the application is finished, and the applying body 10 is moved apart from the applied body A, the applying portion 10a of the applying body 10 is elastically restored to the original position (refer to FIG. 19(a)) as shown in FIG. 19(c). At this time, a predetermined space B is formed in an inner side including the discharge port 10c of the applying portion 10a in the applying body 10.
Accordingly, even if the applying filler L filled in the filling region 1x of the filling member 1 and the air mixing into the applying filler L is expanded due to variation of temperatures or variation of atmospheric pressure at a time of not being used such as a carrying time or the like, the applying filler L is prevented from leaking from the applying body 10 on the basis of the predetermined space B. Accordingly, it is possible to provide the applying filler extruding container 100 having an improved quality.
In this case, in the assembling procedure of the applying filler extruding container 100 described in FIG. 18, if the applying filler L of the filling region 1x is filled in a state in which the applying portion 10a of the applying body 10 is concaved, the applying portion 10a of the applying body 10 is elastically returned after the application so as to make the applying filler extruding container 100 in which the predetermined space B is formed upon filling of the applying filler L. Accordingly, the applying filler L is prevented from leaking from the applying body 10, since this time point, that is, since the time when the product is assembled.
Further, in accordance with the applying filler extruding container 100 on the basis of the present embodiment, as shown in FIG. 2, if the movable body 6 reaches the front to the maximum on the basis of the relative rotation between the main body tube 2 or the filling member 1 and the operating tube 3 by the user, the elastic body 9 is brought into contact with the rear end portion of the attaching portion 10b of the applying portion 10 attached to the leading end portion of the filling member 1, and is elastically deformed on the lines of the rear end portion inclined in the circular ring shape. At this time, the elastic body 9 is elastically deformed more preferably on the basis of the space 9d within the elastic body 9. Further, the applying filler L leaving in an approximately hoof-shaped (oblique circular cylindrical) space (a space including an inclined surface within the container leading end), which cannot be pressed out by the conventional movable body, is sufficiently pressed out with almost no remainder so as to be consumed, on the basis of the elastic deformation of the elastic body 9 mentioned above. Accordingly, there is provided an economic applying filler extruding container 100 in which a waste is reduced.
Further, in accordance with the applying filler extruding container 100, since the structure is made such that the annular groove portion 1g corresponding to the locking portion of the outer peripheral surface of the filling member 1 and the annular protruding portion 2b corresponding to the locking portion between the annular protruding portion 1f and the inner peripheral surface of the main body tube 2, and the protrusion 1h corresponding to the locking portion of the outer peripheral surface of the filling member 1 and the knurling 2a corresponding to the locking portion of the inner peripheral surface of the main body tube 2 are directly locked via no other member, it is possible to make the applying filler extruding container 100 thin. Accordingly, there is provided the applying filler extruding container 100 in which an appearance and a use feeling are improved.
Further, in accordance with the applying filler extruding container 100, the forward moving degree and the returning degree are detected by a user on the basis of the click feeling given to the user by the click mechanism 11. Accordingly, there is provided the applying filler extruding container 100 having an improved usability.
In this case, in the present embodiment, the movable body 6 moves backward, when the main body tube 2 or the filling member 1 and the operating tube 3 are relatively rotated in the other direction corresponding to the opposite direction to the one direction by a user with click feeling. Accordingly, if the relative rotating force intending to move further backward is given to the movable body 6 existing at the maximum retreated position by the user, there is a risk that the shaft body 3c engaging with the movable body 6 is wrenched off in the bottom surface of the operating tube 3. However, in the present embodiment, since a plurality of protruding portions 3g in the bottom surface of the operating tube 3 and a plurality of grooves 6f in the rear end surface of the movable body 6 are engaged in the rotating direction at the maximum backward moving time of the movable body 6, the rotating force intending to move the movable body 6 further backward and applied to the shaft body 3c is also applied to the protruding portion 3g of the operating tube 3 via the groove 6f of the movable body 6 so as to be dispersed, thereby preventing the shaft body 3 from being wrenched off. Accordingly, there is provided the applying filler extruding container 100 in which a quality is further improved.
In this case, the structure may be made such that concave portions are provided in place of the grooves 6f of the movable body 6 for preventing the shaft body 3c from being wrenched off, and the concave portions are engaged with the protruding portions 3g of the operating tube 3 in the rotating direction.
Further, as the other example of the shaft body wrench-off preventing mechanism, on the contrary of the shaft body wrench-off preventing mechanism mentioned above, as shown in FIG. 20, the structure may be made such that the convex portions 6h protruding to the rear side are provided at a plurality of positions along the peripheral direction in the rear end surface of the movable body 6, and a plurality of concave portions 3h which the convex portions 6h of the movable body 6 move forward into at the maximum retreated time of the movable body 6 and engage with in the rotating direction are provided in the peripheral edge of the shaft body 3c in the bottom surface of the operating tube 3.
Further, in place of the applying body 10 shown in FIG. 17, an applying body 15 having a plurality of discharge ports 15c for discharging the applying filler L may be used as shown in FIG. 21.
Further, an applying body 21 shown in FIG. 22 may be used in place of the applying body 10 shown in FIG. 17. The applying body 21 is formed in an approximately columnar shape, as shown in FIG. 22(b), and is structured such that a portion near a center portion of the leading end surface is curved so as to protrude. Further, a discharge port 21c for discharging the applying filler L is provided in the center thereof so as to pass through in an axial direction. Further, an annular groove portion 21e concaved at a predetermined length from a rear end surface to a leading end side is provided in a peripheral edge portion of a rear end surface of the applying body 21. The annular groove portion 21e is provided so as to deflect an outer portion from the annular groove portion 21e to an axial side so as to easily pressure insert, at a time of pressure inserting the applying body 21 to the opening of the filling member 1. Further, the annular groove portion 21d concaved to the axial side is provided as a structure engaging with the peripheral edge portion 1j forming the opening of the filling member 1, in an outer peripheral surface of the applying body 21.
Further, the applying body 21 is pressure inserted to the opening of the filling member 1, and the annular groove portion 21d thereof is engaged with the peripheral edge portion 1j forming the opening of the filling member 1, thereby being attached to the filling member 1 so as not to be disconnected, and being structured such as to be positioned in the opening of the filling member 1.
The applying body 21 is elastically deformed in such a manner as to be concaved to a rear side by being pressed to the applied portion A at a time of application, as shown in FIG. 22(a), and is elastically restored to the original position at a time of being apart from the applied portion A. As shown in FIG. 22(b), a predetermined space B is formed in an inner side (a rear side) of the applying body 21 after application. Accordingly, it is possible to obtain the same effect as that of the applying filler extruding container 100 as mentioned above. In this case, in the embodiment shown in FIG. 22, the leading end surface having the opening 1c of the filling member 1 is formed as a surface which is vertical to the axial direction.
Further, a filling member 16 and an applying body 17 shown in FIG. 23 may be used. The filling member 16 is different from the filling member 1 in a point that the peripheral edge portion forming an opening 16c for discharging the applying filler L is structured such as to have an annular fold-back portion 16d folded back to an outer side, and a bag-shaped annular groove portion 16e for engaging the applying body 17 is formed by the annular fold-back portion 16d. Further, the applying body 17 is different from the applying body 10 in a point that an annular attaching portion 17b protruding to an axial side and a rear side is provided in a peripheral edge portion of a curved disc-shaped applying portion 17a having a discharge port 17c and curved to an outer side.
Further, the applying body 17 is structured such that an attaching portion 17b moves forward to the annular groove portion 16e of the filling member 16 so as to be engaged, thereby being attached to the filling member 16 so as not to be disconnected, and an applying portion 17a covers the opening 16c of the filling member 16. Even in the case that the filling member 16 and the applying body 17 are employed, the same operations and effects as those of the applying filler extruding container 100 mentioned above can be achieved.
Further, as shown in FIGS. 24 to 26, the structure may be made such that the applying body 20 is elastically restored by an elastic body 19 within a filling member 18 constituting the container.
The filling member 18 is provided with a filling member main body 18a coupled to the main body tube 2 so as to be non-rotatable, and immobile in the axial direction, a filling member leading end portion 18b attached to a leading end portion of the filling member main body 18a, and an applying body holding portion 18c attached to the filling member leading end portion 18b and holding the applying body 20, and is entirely formed in an approximately cylindrical shape.
The filling member main body 18a receives most of the applying filler L to be filled. The filling member leading end portion 18b is structured such that a leading end surface having an opening 18d for discharging the applying filler L is formed as a surface vertical to the axial direction, and is provided with a discharge passage 18e communicating from the opening 18d in the leading end surface to a rear end surface. The discharge passage 18e is structured such that an approximately center portion in the axial direction is formed as a small-diameter narrow passage 18f, and a front side and a rear side of the narrow passage 18f are formed as large-diameter expanded passages 18g and 18h. 
The applying body 20 is constituted by an elastic body made of a porous material, for example, an urethane foam, a fine net-like material or the like, and is formed in a curved disc shape curved to an outer side. A peripheral edge portion bent to a rear side in the applying body 20 is engaged with a leading end portion of the filling member leading end portion 18b and engaged with a leading end portion of the applying body holding portion 18c so as to be pressed, whereby the applying body 20 is attached to the filling member 18, and covers the opening 18d of the filling member 18.
Further, a compression spring 19 serving as the elastic body is arranged in a front side expanded passage 18g of the filling member leading end portion 18b. The compression spring 19 is arranged so as to be pinched between a back surface of the applying body 20 and a peripheral edge portion of the narrow passage 18f of the filling member leading end portion 18b, and is structured such as to always energize the applying body 20 to the outer side.
Further, since the applying filler extruding container having the structure mentioned above is structured such that the filling member 18 in which the applying filler L is filled is inserted and attached to the leading end side of the main body side assembly 40, it is easy to assemble after the applying filler L is filled in the filling member 18, and there is provided a state in which the applying filler L is sufficiently filled in a filling region 18x between an inner side of the applying body 20 constituting the leading end portion of the filling member 18, and the elastic body 9 attached to the leading end of the movable body 6 of the main body side assembly 40.
Accordingly, in the applying filler extruding container, in the case that the user relatively rotates the main body tube 2 or the filling member 18 and the operating tube 3 while accompanying the click feeling so as to move forward the movable body 6 at the first applying time after buying the applying filler extruding container, the applying filler L is rapidly discharged from the porous portion functioning as a discharge port of the applying body 20 without repeating the relative rotation more than necessary, because the applying filler L is sufficiently filled in the filling region 18x. 
Further, when pressing the applying body 20 to the applied portion A and applying the applying filler L to the applied portion A in the same manner as described in FIG. 19(b) under the state in which the applying filler L is discharged as mentioned above, the applying body 20 is elastically deformed so as to be concaved to the rear side against the energizing force of the compression spring 19 on the basis of the pressing to the applied portion A. When the application is finished and the applying body 20 is moved apart from the applied portion A, the applying body 20 is elastically restored to the original position shown in FIG. 25 on the basis of the energizing force of the compression spring 19. The predetermined space B is formed in the inner side of the applying body 20 at this time. Accordingly, even if the applying filler L filled in the filling member 18 and the air mixing into the applying filler L are inflated due to the variation of temperature and the variation of atmospheric pressure, the applying filler L is prevented from leaking from the applying body 20 on the basis of the predetermined space B.
In this case, in the same manner as the case of the applying filler extruding container 100 mentioned above, if the applying filler L is filled in a state in which the applying body 20 is concaved, the applying body 20 is elastically returned on the basis of the energizing force of the compression spring 19 after the application so as to make the applying filler extruding container in which the predetermined space B is formed upon filling of the applying filler L. Accordingly, the applying filler L is prevented from leaking from the applying body 20, since this time point, that is, since the time when the product is assembled.
Further, as shown in FIG. 25, if the movable body 6 moves forward to the maximum on the basis of the relative rotation between the main body tube 2 or the filling member 18 and the operating tube 3 by the user, the elastic body 9 is brought into contact with the inclined surface in the leading end side of the rear side expanded path 18h so as to be elastically deformed, and the leading end portion of the elastic body 9 bulges so as to move forward to the front side expanded passage 18g through the narrow passage 18f. Accordingly, the applying filler L is well pressed out so as to be consumed. In this case, the other operations and effects are the same as those of the applying filler extruding container 100 mentioned above.
The description is particularly given above of the present invention on the basis of the embodiments, however, the present invention is not limited to the embodiments mentioned above, but a cilia or the like may be planted on the outer surfaces of the applied bodies 10, 15, 17, 20 and 21 or a brush formed by bundling tapered polyester fibers may be attached.
In this case, the male threads 6b include intermittently arranged projection groups or spirally and intermittently arranged projection groups which have the same function as the thread ridge. Further, the female threads 4c include intermittently arranged projection groups, or spirally and intermittently arranged projection groups which have the same function as the thread ridge.
