Description

  The present invention relates to a refill container.

Conventionally, as this type of refill container, as described in, for example, Patent Document 1 below, a container main body for storing contents to be refilled in the present container, and a mouth mounted on the mouth of the container main body There is known a refill container that includes an inner stopper that closes the portion, and is refilled by screwing the inner stopper into the mouth of the container.
The above-described inner plug is formed with a spout for pouring out the contents and a seal portion for closing the spout. The seal portion is made of, for example, a lid provided with a pull top.

  In the refill container having the above-described configuration, for example, the pull top is first pulled up to open the spout of the inner plug. Subsequently, the refill container is placed in an upright posture (the mouth portion is in an upward posture), and the mouth portion of the main container in an inverted posture (the mouth portion is in a downward posture) is screwed onto the inner plug of the refill container. Thereafter, the refill container and the main container are reversed to bring the main container into an upright posture and the refill container into an inverted posture. As a result, the contents in the refill container are refilled into the main container through the insides of the mouths of the refill container and the main container.

JP 2000-159249 A

However, in the above-described conventional refill container, after opening the spout of the inner stopper, it is necessary to screw the mouth of the main container into the inner stopper, and then turn the refill container and the main container upside down. Work was easy to become complicated.
Also, since the mouth of the container is screwed into the refill container after opening the spout of the inner plug, if the refill container is accidentally tilted during the screwing operation, the contents in the refill container will spill. There was a risk of getting out.
Further, since the container is placed in an inverted position when the mouth of the container is screwed onto the inner plug, the contents in the container are likely to spill if the contents remain inside the container. Therefore, it was difficult to perform refilling work after the contents in the container were used up.

  The present invention has been made in view of such circumstances. The purpose of the present invention is to enable easy refilling work and to prevent the contents from being spilled during refilling. An object of the present invention is to provide a refill container that can be refilled even if it remains.

In order to achieve the above object, the present invention provides the following means.
The refill container according to the present invention includes a container main body in which the contents to be refilled in the container are accommodated, a mounting cylinder attached to the mouth of the container main body, and a guide cylinder arranged inside the mounting cylinder in the radial direction. A base cylinder member having a bottomed cylindrical pour cylinder that is slidably fitted in the container axis direction in the guide cylinder and has a pour hole that opens toward the side, and An operating member that surrounds the dispensing cylinder from the outside in the radial direction, and is externally attached to the guide cylinder so as to be slidable in the container axial direction, and has a connecting cylinder part connected to the inlet part of the container; The base cylinder member is provided with a seal portion that is in close contact with the outer peripheral surface of the extraction cylinder and blocks communication with the extraction hole and the inside of the container body, , Between the pouring hole and the bottom wall portion of the pouring cylinder along the container axial direction Between a seal position where the seal portion is disposed and a communication position where the extraction hole is disposed inside the container body along the container axial direction with respect to the seal portion and opened in the container body. It is characterized by being slidably movable.

According to the refill container of the present invention, when the contents are refilled in the main container, first, the connecting cylinder part of the operation member is connected to the inlet part, and the refill container and the main container are combined. And the operation member is moved toward the container main body side by relatively moving the container main body and the main container of the refill container along the container axial direction.
Thereby, since the pouring hole is arranged inside the container axial direction from the seal part and opens into the container main body, the inside of the container main body of the refill container and the inside of the inlet of the main container are disposed through the pouring hole. The contents in the container main body are poured out into the inlet through the outlet hole and the outlet cylinder. Thereby, the contents in the container body are refilled in the container.

As described above, after connecting the connecting cylinder part to the inlet part and combining the refill container and the main container, the container main body and the main container are moved relatively close to each other along the container axial direction. Since the contents can be refilled, refilling work can be facilitated.
In addition, when refilling, the container main body and the main container communicate with each other through the spout hole in a state where the connecting cylinder part and the inlet part of the main container are connected. In addition, the contents are refilled into the container through the dispensing cylinder. As a result, it is possible to prevent the contents from spilling, and it is possible to perform refilling work without placing the container in an inverted position, and the contents in the container remain. Can also refill the contents.

Moreover, by forming an extraction hole that opens toward the side of the bottomed cylindrical extraction cylinder, the refill container can be simply moved by moving the extraction cylinder toward the container body relative to the base cylinder member. Can be opened. Therefore, for example, the refilling operation can be simplified compared to the case where a separate inner plug is provided at the mouth of the container body.
Also, for example, unlike when the mouth of the container body is closed with a breakable stopper, the stopper that has been broken during refilling falls into the container body or closes the mouth of the container body again. There is no risk of getting stuck. That is, there is no need to break the stopper portion, and the contents in the container body can be refilled more easily and efficiently by merely sliding the pouring tube.

  Further, in the refill container according to the present invention, a restricting member for restricting movement of the operation member toward the container main body with respect to the base tube member is disposed between the mounting tube and the connecting tube portion. May be.

  In this case, since a regulating member that regulates the sliding movement of the operating member is arranged between the mounting cylinder and the connecting cylinder part, even if an external force is unexpectedly applied to the refill container at the distribution stage or the like, It is possible to prevent the operation member from moving to the communication position by restricting the sliding movement of the operation member, and to prevent the refill container from being opened unexpectedly.

  Further, in the refill container according to the present invention, the dispensing cylinder is located on the bottom wall portion side, is located on the opening portion side with a small diameter portion where the dispensing hole is formed, and is located on the opening portion side. A large-diameter portion formed in a large diameter and slidably fitted in the guide tube, and the seal portion protrudes radially inward from the guide tube. The small diameter portion may be slidably fitted inside.

  In this case, since the small-diameter portion reduced in diameter with respect to the large-diameter portion and the seal portion reduced in diameter relative to the guide tube are in close contact with each other, Compared with the case where is closely in contact with the entire region in the container axial direction, the contact area between the extraction tube (small diameter portion) and the seal portion can be reduced. Thereby, the surface pressure between the small-diameter portion and the seal portion can be improved, the sealing performance can be improved, and an increase in sliding resistance at the time of opening (at the time of sliding movement) can be suppressed, so that the dispensing cylinder can be easily moved.

  In the refill container of the present invention, at the communication position, the opening side end of the extraction tube in the extraction hole and the seal portion are arranged at equivalent positions along the container axial direction. May be.

In this case, the contents located closer to the container body than the seal portion can be poured into the container through at least the dispensing hole.
In addition, in the communication position, when the opening side end portion of the dispensing tube in the dispensing hole is located inside the container body with respect to the seal portion, the contents flow between the dispensing tube and the guide tube. Therefore, it is possible to refill the contents without waste while maintaining the sealing performance between the dispensing cylinder and the seal portion.

  According to the refill container according to the present invention, the refilling operation can be easily performed, and it is difficult to spill the contents at the time of refilling, and the refilling work can be performed even when the contents in the container remain. It can be carried out.

  In addition, the container main body 2, the base cylinder member 5, and the operation member 7 mentioned above are arrange | positioned in the state in which each center axis line was located on the common axis. In the present embodiment, this common axis is referred to as a container axis O, and in the refill container 1 described above, the operation member 7 side along the container axis O is referred to as an upper side, and the container body 2 side is referred to as a lower side. A direction perpendicular to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

The mounting cylinder 3 includes a seal cylinder part 10 fitted in the mouth part 2a of the container body 2, an outer cylinder part 11 screwed to the outer surface of the mouth part 2a of the container body 2, and an upper end of the outer cylinder part 11 And a connecting ring 12 disposed on the opening edge of the mouth portion 2a.
The guide tube 4 extends upward from the inner peripheral edge of the connecting ring 12. The guide cylinder 4 is formed to have the same diameter as the seal cylinder part 10 and is longer in the vertical direction than the seal cylinder part 10. That is, the guide tube 4 extends from the inner periphery of the connecting ring 12 and the seal tube portion 10 extends downward.

  The operating member 7 is fitted into the guide tube 4 so as to be movable in the vertical direction, and has a bottomed cylindrical pouring tube 21 in which a pouring hole 6 opened to the side is formed, The cylinder 21 is enclosed from the outside in the radial direction, and is connected to the guide cylinder 4 so as to be movable in the vertical direction, and has a connecting cylinder portion 22 connected to the inlet portion 52 of the container 51. .

  The connection cylinder part 22 is provided with the main body cylinder 25 extrapolated by the guide cylinder 4, and the cyclic | annular stopper part 26 projected toward the outer side of radial direction at the lower end part of the main body cylinder 25. As shown in FIG. In addition, as for the connection cylinder part 22, it is preferable that the main body cylinder 25 is undercut fitting with respect to the guide cylinder 4 mentioned above. Thereby, the upward movement of the connecting cylinder part 22 is restricted, and the operation member 7 can be prevented from coming off the base cylinder member 5.

The main body cylinder 25 is formed with a guide plate 27 that protrudes outward in the radial direction and extends substantially over the entire length in the vertical direction. A plurality of guide plates 27 are formed in the connecting cylinder portion 22 at intervals in the circumferential direction, preferably at equal intervals in the circumferential direction. Further, the upper end portion of the guide plate 27 gradually decreases in the amount of protrusion toward the outside in the radial direction from the lower side toward the upper side, and the lower end portion is connected to the stopper portion 26.
The outer diameter of the stopper part 26 is formed larger than the outer diameter of the mounting cylinder 3, and the outer peripheral edge of the stopper part 26 projects outward in the radial direction from the outer peripheral edge of the connecting ring 12 (outer cylinder part 11). ing. In addition, as the stopper part 26, it may replace with cyclic | annular form and may employ | adopt the board | plate body arrange | positioned by the circumferential direction at intervals, for example. In this case, you may use the space | interval of the board bodies adjacent in the circumferential direction as an air replacement hole.

The dispensing cylinder 21 is disposed on the radially inner side of the connecting cylinder part 22, and the upper end part thereof is connected to the upper end part of the connecting cylinder part 22 via an annular connecting plate 29. Specifically, the pouring cylinder 21 is located on the bottom wall portion 36 side and is connected to the bottomed tubular small diameter portion 33 in which the pouring hole 6 is formed and the upper end of the small diameter portion 33 and is directed upward. The taper portion 32 is gradually enlarged in accordance with the taper portion 32 and the upper end (opening portion side) of the taper portion 32. The taper portion 32 has a larger diameter than the small diameter portion 33 and is slidable in the guide tube 4 described above. And a fitted large-diameter portion 31. Therefore, a gap is formed between the small diameter portion 33 and the guide tube 4 and the seal tube portion 10 in the radial direction along the circumferential direction.
The extraction hole 6 has a long hole shape with the vertical direction as the major axis direction, and penetrates the small diameter portion 33 in the radial direction so as to communicate the inside and the outside of the small diameter portion 33. Note that a plurality of the extraction holes 6 are formed at intervals in the circumferential direction, preferably a plurality at equal intervals in the circumferential direction. In this case, the two extraction holes 6 of the present embodiment are formed so as to be opposed to each other in the circumferential direction, that is, in the radial direction, but only one extraction hole 6 may be formed. .

Here, the lower end of the above-described seal cylinder portion 10 is continuously provided with a throttle portion 34 that is gradually reduced in diameter toward the lower side, and the lower end of the throttle portion 34 is connected to the outlet hole 6 and the inside of the container body 2. A seal portion 35 for blocking the communication is formed. The seal portion 35 is formed in a cylindrical shape extending coaxially with the container axis O from the lower end of the throttle portion 34 downward, and its inner peripheral surface is in close contact with the outer peripheral surface of the small diameter portion 33. Therefore, the small diameter portion 33 described above is slidably fitted into the seal tube portion 10.
In this case, the above-described operation member 7 has a pour hole from the seal position (see FIG. 1) where the seal portion 35 is disposed between the pour hole 6 and the bottom wall portion 36 of the small diameter portion 33 along the vertical direction. 6 is arranged below the seal portion 35 and slides to a communication position (see FIG. 5) opened in the container body 2. At the sealing position, the sealing portion 35 has an upper end position (a boundary portion with the throttle portion 34) positioned below the above-described pouring hole 6 and a lower end position positioned above the bottom wall portion 36. Yes. Therefore, the seal portion 35 is in close contact with the entire area in the vertical direction on the inner peripheral surface from the pouring hole 6 of the small diameter portion 33 to the bottom wall portion 36.

As shown in FIGS. 1 and 2, the restricting member 8 described above includes a support wall 41 connected to a part of the outer peripheral edge of the stopper portion 26 in the circumferential direction, and a hinge portion 42 on the support wall 41. And a movable wall 43 connected rotatably.
The support wall 41 is formed in an arc shape along the outer peripheral edge of the stopper portion 26 in a top view and extends along the vertical direction. Moreover, the hinge part 42 mentioned above is formed in the one end side of the circumferential direction in the support wall 41, and the latching protrusion 44 which protrudes toward the outer side of radial direction is formed in the other end side of the circumferential direction.

The movable wall 43 is formed to have a length in the vertical direction equivalent to that of the support wall 41, and is disposed between the stopper portion 26 and the connecting ring 12, and is a restriction position that restricts the downward movement of the operation member 7 ( From FIG. 1), it retracts from between the stopper portion 26 and the connecting ring 12, and rotates to a retracted position (see FIG. 4B) that allows the operation member 7 to move downward. .
Specifically, the movable wall 43 includes an extending part 45 extending radially inward from the hinge part 42, and a main body restricting part 46 continuously provided from the radially inner end of the extending part 45. , And a knob piece 47 extending from the opposite side of the extending portion 45 in the main body regulating portion 46 toward the outside in the radial direction with the container shaft O interposed therebetween.

The main body restricting portion 46 is formed in a C shape in a top view and is disposed so as to surround the guide tube 4. Further, a locking projection 48 that protrudes outward in the radial direction is formed on one end side in the circumferential direction of the main body restricting portion 46. The locking protrusion 48 is adapted to be undercut fitted to the locking protrusion 44 of the support wall 41 at the retracted position.
The knob piece 47 protrudes from the other end side in the circumferential direction of the main body restricting portion 46 toward the outside in the radial direction, and a pair of engaging convex portions 49 protrudes downward from the stopper portion 26 at the restricting position described above. Engaged between them.

Next, a method for refilling the contents W from the refill container 1 configured as described above into the main container 51 will be described.
First, as shown in FIG. 3, the refill container 1 is placed above the main container 51 with the refill container 1 in the inverted posture and the main container 51 in the upright posture. Then, the refill container 1 and the main container 51 are moved relatively close to each other while aligning, and the stopper portion 26 of the operation member 7 is brought into contact with the opening edge of the inlet portion 52 of the main container 51. The refill container 1 and the main container 51 are combined. At this time, the refill container 1 and the main container 51 are combined in a state where the connecting cylinder portion 22 of the operation member 7 is inserted into the inlet portion 52 of the main container 51.

Here, in the present embodiment, as described above, the refill container 1 is turned upside down, so that the top and bottom of the refill container 1 are inverted, and the operation member along the container axis O direction in the refill container 1 in the inverted position. The 7 side is the lower side, and the container body 2 side is the upper side.
At this time, since the seal portion 35 of the refill container 1 is in close contact with the small-diameter portion 33 between the pouring hole 6 and the bottom wall portion 36 along the vertical direction, the inside of the pouring hole 6 and the container body 2 Communication is blocked. Therefore, even if the refill container 1 is in an inverted posture, the content W in the container body 2 does not flow out through the pouring hole 6. Furthermore, since the restricting member 8 is disposed between the connecting ring 12 of the base cylinder member 5 and the stopper portion 26 of the operating member 7, the downward movement of the operating member 7 is restricted. For this reason, the inside of the container body 2 and the inside of the container 51 do not communicate with each other through the pouring hole 6. In addition, a plurality of guide plates 27 are formed in the connecting cylinder portion 22 at intervals in the circumferential direction, and the outer peripheral surface thereof is inserted and fitted into the inner surface of the injection port portion 52 of the container 51. 22 can be stably connected to the inlet 52 of the container 51.

  Next, as shown in FIG. 4, the restriction of the operation member 7 by the restriction member 8 is released. Specifically, the knob piece 47 of the regulating member 8 is picked and the movable wall 43 is rotated around the hinge portion 42. Thereby, the movable wall 43 retracts from between the base tube member 5 and the operation member 7, and the restriction of the operation member 7 is released. Note that the movable wall 43 can be held in the retracted position by fitting the locking projection 48 to the locking projection 44 of the support wall 41 undercut.

  In this embodiment, the case where the restriction member 8 is released after the refill container 1 is assembled to the main container 51 has been described. However, after the movable wall 43 is retracted, the refill container 1 is attached to the main container 51. It may be assembled. It is preferable that the movement of the operation member 7 is suppressed even after the restriction by the restriction member 8 is released. As such a configuration, in this embodiment, after fitting the extraction cylinder 21 to the guide cylinder 4, the large-diameter portion 31 of the extraction cylinder 21 is slidably fitted to the guide cylinder 4, The small diameter portion 33 is slidably fitted to the seal portion 35. However, the present invention is not limited to this, and an engaging portion (protrusion or recess) that engages with an engaging portion (protrusion or recess) formed on the outer surface of the dispensing tube 21 and that can be overcome by movement of the operation member 7 is provided as a guide tube. 4 or the like can be adopted.

  Then, as shown in FIG. 5, the container body 2 of the refill container 1 and the main container 51 are relatively moved along the vertical direction. Then, the opening edge of the inlet 52 of the main container 51 pushes the stopper 26 toward the container main body 2, so that the operation member 7 moves toward the container main body 2. At this time, the outer peripheral surface of the large-diameter portion 31 slides on the inner peripheral surface of the guide tube 4 and the outer peripheral surface of the small-diameter portion 33 slides on the inner peripheral surface of the seal portion 35. However, the operation member 7 slides toward the container body 2 side.

  Then, the protrusion amount from the seal portion 35 of the small-diameter portion 33 along the vertical direction increases with respect to the seal position (see FIG. 1), and the small-diameter portion 33 enters the container main body 2, so that the extraction hole 6 is formed. Open in the container body 2 (communication position). The operation member 7 is moved to a position where the stopper portion 26 abuts on the connection ring 12 of the base cylinder member 5. As a result, the entire pouring hole 6 of the operation member 7 opens into the container body 2. At this time, the lower end position of the pouring hole 6 and the seal portion 35 are arranged at equivalent positions along the vertical direction.

  Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the inlet 52 of the main container 51 communicate with each other through the inside of the extraction hole 6 and the extraction cylinder 21. Then, the contents W accommodated in the container body 2 of the refill container 1 are poured into the dispensing cylinder 21 through the dispensing hole 6, and then into the inlet 52 of the main container 51 through the dispensing cylinder 21. (Arrow A shown in FIG. 5). As a result, the contents W can be refilled from the refill container 1 to the main container 51.

As described above, according to the refill container 1 of the present embodiment, after the refill container 1 and the main container 51 are combined in a state where the stopper portion 26 is in contact with the opening edge of the inlet portion 52, the container body 2 Since the contents W can be refilled by a simple work of relatively moving the container 51 and the container 51 in the vertical direction, the refilling work can be facilitated.
Further, when the refill is performed, the refill container 1 and the main container 51 communicate with each other through the extraction hole 6 in a state where the connecting cylinder portion 22 of the refill container 1 and the injection port 52 of the main container 51 are connected. Simultaneously with opening of the refill container 1, the contents W are refilled into the main container 51 through the pour hole 6 and the pour cylinder 21. Thereby, it is possible to suppress the spilling of the contents W, and it is possible to perform the refilling operation without setting the main container 51 in the inverted posture, and the contents W in the main container 51 remain. Even in this case, the contents W can be refilled.

In addition, when the refill is performed, the stopper portion 26 and the connecting ring 12 are kept in contact with each other, so that it is possible to prevent the positions and postures of the main container 51 and the refill container 1 from becoming unstable. Further, it is possible to realize the refilling operation more easily and to make it difficult to spill the contents W at the time of refilling.
Further, since the operation member 7 can be stabilized by bringing the stopper portion 26 into contact with the opening edge of the injection port portion 52 as described above, the operation member 7 can be moved smoothly along the vertical direction. Can do. Therefore, the pouring hole 6 can be opened in the container body 2 without requiring an excessive force. In this respect, the refilling operation is easy to perform.

Moreover, since the regulating member 8 that regulates the downward movement of the operation member 7 is arranged between the base tube member 5 and the operation member 7, it is assumed that an external force is unexpectedly applied to the refill container 1 at the distribution stage or the like. In addition, the movement of the operation member 7 can be restricted to prevent the operation member 7 from moving to the communication position, and the refill container 1 can be prevented from being opened unexpectedly.
Furthermore, at the time of refilling, the regulating member 8 can be retracted in a state where the refill container 1 and the main container 51 are combined. In this case, since the operation member 7 can be moved only after the container body 2 is combined with the main container 51 while the dispensing cylinder 21 is sealed with the sealing portion 35 and then the regulating member 8 is retracted, the contents during refilling work It is possible to reliably prevent the object W from spilling.

Moreover, in the present embodiment, by forming the extraction hole 6 that opens to the side in the bottomed cylindrical extraction cylinder 21, the extraction cylinder 21 is placed on the container body 2 side with respect to the base cylinder member 5. The refill container 1 can be opened simply by moving it toward. Therefore, for example, the refilling operation can be simplified compared to the case where a separate inner plug is provided in the mouth 2a of the container body 2.
In addition, for example, unlike the case where the mouth portion 2a of the container body 2 is closed with a breakable stopper portion, the stopper portion that is broken during refilling falls into the container body 2 or the mouth portion 2a of the container body 2 is removed. There is no risk of closing again. That is, there is no need to break the stopper portion, and the contents W in the container body 2 can be refilled more simply and efficiently simply by sliding the pouring cylinder 21.

Furthermore, since the small-diameter portion 33 reduced in diameter with respect to the large-diameter portion 31 and the seal portion 35 reduced in diameter relative to the guide tube 4 are in close contact with each other, the dispensing tube 21 and the seal portion 35 and The contact area between the small diameter portion 33 and the seal portion 35 can be reduced as compared with the case where the guide tube 4 is in close contact with the entire area in the vertical direction. As a result, the surface pressure between the small-diameter portion 33 and the seal portion 35 can be improved, the sealing performance can be improved, and an increase in sliding resistance at the time of opening (moving) can be suppressed, so that the operation member 7 can be easily moved. .
Further, at the communication position (see FIG. 5) where the pouring hole 6 opens into the container body 2, the lower end position of the pouring hole 6 and the seal portion 35 are disposed at the same position in the vertical direction, so that the seal The contents W located above the portion 35 can be poured into the main container 51 through at least the pouring hole 6.
When the lower end position of the pouring hole 6 is located above the seal portion 35 (inside the container main body 2) at the communication position, the content W is placed between the pouring cylinder 21 and the guide cylinder 4. Therefore, the contents W can be refilled without waste while maintaining the sealing performance between the dispensing cylinder 21 and the seal portion 35.

  The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the restricting member 8 in the above-described embodiment is configured to be able to turn the movable wall 43 via the hinge portion 42. However, the present invention is not limited to this. For example, as shown in FIG. You may connect to the connection ring 12 integrally via the part 71. FIG.
Specifically, the regulating member 72 shown in FIG. 6 is formed in a cylindrical shape arranged coaxially with the container axis O, and surrounds the guide cylinder 4 from the outside in the radial direction over almost the entire circumference. The restricting member 72 is configured to restrict the movement of the operation member 7 between the connecting ring 12 of the base tube member 5 and the stopper portion 26 of the operation member 7. Further, a knob piece 73 whose length in the vertical direction is gradually reduced along the circumferential direction is formed on a part of the regulating member 72 in the circumferential direction. In the vicinity of the portion where the knob piece 73 is formed, the restricting member 72 is preferably divided in the circumferential direction by a slit (not shown) extending in the vertical direction or connected so as to be capable of being divided.
The weakening portion 71 is formed thinner than the connecting ring 12 and the regulating member 8, and is formed at the lower end of the regulating member 8 over the entire circumference. The weakened portion 71 is not limited to a thin wall, and can be appropriately changed in design, for example, formed in a perforated shape.

Further, if the restriction member described above is disposed between the base tube member 5 and the operation member 7, the restriction member 5 and the operation member 7 may be connected to either the base tube member 5 or the operation member 7. It may be provided separately from the member 7.
As a configuration in which the restricting member is provided separately from the base tube member 5 and the operation member 7, the restricting member 81 shown in FIG. 7 has a C-shaped cross section along the radial direction, and the guide tube 4 is fitted inside. A deformable C-ring portion 82, and a knob piece 83 projecting outward in the radial direction on the opposite side of the opening extending in the vertical direction across the container axis O in the C-ring portion 82; It has.

In the above-described embodiment, the case where the base tube member 5 and the operation member 7 are configured separately has been described.
