Description

  The present invention provides a lid that realizes a tightly-sealed state that can be attached to a container mouth portion of a beverage container body in a packing attachment posture to which the packing is attached, and prevents liquid leakage from the beverage container body in the attached state. The present invention relates to a beverage container provided.

A beverage container provided with a beverage container main body for storing a beverage and a lid attached to a container mouth portion of the beverage container main body is well known.
When the lid is attached to the beverage container body, the male container is usually provided on the outer side of the beverage container body, the female screw part is provided on the inner side of the lid body, and the lid body is attached to the beverage container body. A structure that can be mounted is employed (Patent Document 1, Patent Document 2).

  A lid can be fixedly attached to the lid, and a packing attachment part is provided on the container mouth side of the closure, and the lid is attached to the beverage container body in a packing attachment posture with the packing attached to the packing attachment part. Then seal the container mouth. Thereby, it can prevent that a drink leaks from a drink container main part. In other words, the lid with the packing attached, which is in a normal use state, is attached to the container mouth portion of the beverage container body to realize a sealed state.

In Patent Document 1, the packing 16 is a packing provided for this purpose, and the packing 16 is attached to a packing mounting collar 15 provided under the packing pressing collar 14. In the beverage container stopper disclosed in Patent Document 2, a packing 33 is provided for this purpose. The packing 33 is attached to the seal member mounting portion 32.
With regard to the removal and attachment of these packings 16 and 33, the form in the vicinity of the packing attachment portion does not change.

  Both of the technologies disclosed in these documents make up the lid with a plurality of parts, allowing the lid to be disassembled and assembled, and improving the cleanability of each part to keep the lid clean. Care is also good. When cleaning, a packing (so-called plug packing) can also be removed.

  The lid body having the disassembled structure disclosed in these Patent Documents 1 and 2 improves the careability, but on the other hand, the work for disassembling and assembling occurs, causing forgetting to assemble the parts when the lid is assembled. was there.

  Therefore, in order to prevent forgetting to assemble the inner stopper, a configuration is adopted in which the lid cannot be attached to the beverage container body when the inner stopper is not assembled.

JP-A-7-204108 JP, 2015-13675, A

However, if the plug packing is also removed, it may be forgotten to attach the plug packing to the inner plug.
If the lid packing is turned over before it is attached to the container mouth, the user has no opportunity to know whether or not he / she has forgotten to install the plug packing. For this reason, problems such as leakage due to forgetting to install the plug packing may occur during use. That is, the inner plug itself is attached to the inside of the lid, but when the packing is forgotten, a sealed state that prevents liquid leakage cannot be realized.

  In view of this situation, the main problem of the present invention is to ensure that the packing for sealing the container mouth of the beverage container main body is securely attached, and that unexpected problems such as leakage occur when the packing is forgotten. It is the point which provides the beverage container which does not have.

The characteristic configuration of the present invention realizes a tightly plugged state in which the packing can be attached to the container mouth portion of the beverage container main body in a packing attachment posture to which the packing is attached, and prevents liquid leakage from the beverage container main body in the attached state. A beverage container with a lid,
In the configuration where the lid body takes a posture different from the packing attachment posture in the packing removal posture where the packing is removed,
In the packing removal posture, regarding the mounting of the lid to the container mouth, the mounting to realize the sealed state is not possible.

  According to this configuration, in a state where the lid is in the packing removal posture, the lid cannot be attached to the container mouth portion to realize a sealed state. The user of the beverage container cannot attach the lid itself to the main body of the beverage container at the stage where the lid is to be attached (in this case, of course, it is not sealed), or cannot reach the sealed state. Recognizing this, it can be recalled that the packing may remain removed and needs to be installed. As a result, it is possible to solve the problem that the lid is attached to the beverage container main body without the packing being attached and the liquid leaks from the inside of the beverage container.

  The characteristic configuration of the present invention is that the lid body is provided with a blocking portion that prevents the lid body from being mounted on the container mouth side in the packing removal posture.

  According to this configuration, at the stage of attaching the lid body to the beverage container body, the blocking portion prevents the lid body from being attached to the container mouth side, thereby preventing the lid body from being attached in the packing removal posture. .

  The characteristic configuration of the present invention is configured as a cylindrical member in which the lid body and the container mouth portion share a central axis, and the blocking portion extends toward the container mouth side of the lid body along the central axis. The point is to prevent the movement of.

  According to this configuration, when the lid is about to be attached to the container mouth portion, the blocking portion prevents axial movement along the common central axis, so that the packing cannot be attached due to the lid being unmountable. In this case, the beverage container is not used (therefore no problems such as leakage). In addition, since the lid cannot be attached, the user can think of the possibility of forgetting to install the packing.

A characteristic configuration of the present invention is that the lid body includes a screw body that is screwed into the container mouth portion;
A packing attaching portion to which the packing is attached is provided, and an inner plug that can be fixed to the lid main body, and the packing is attached to the packing attaching portion to fix the inner plug to the lid main body. There is a fixing control means that is in a packing mounting posture, and has a packing removal posture in which the inner plug is released from the lid body when the packing is removed from the packing mounting portion.

  According to this configuration, by providing the fixing control means on the lid body in which the inner plug to which the packing is attached is originally fixed to the lid body, the inner plug is removed from the lid body when the packing is removed. It is released and cannot be fixed substantially. For example, as shown in an embodiment described later, the inner plug can rotate in the circumferential direction with respect to the lid body. As a result, this released state allows the user to know that there is a possibility that the packing is not attached, and can recognize that it is necessary to install the packing.

  The characteristic configuration of the present invention is characterized in that the fixing control means is provided in the inner plug and swings between a packing attachment posture and a packing removal posture, a protrusion provided in the lid body, As the swinging member swings, the position of the swinging member is allowed to move so that the protruding portion can be engaged and fixed with the swinging member in the packing mounting posture, and the protruding portion is moved to the position in the packing removal posture. The movement body is provided with a movement restricting rocking end portion for changing to a restriction position for restricting the movement of the position of the rocking member to be engaged and fixed.

  The fixing control means for controlling the fixing of the inner plug to the lid main body (engagement fixing or non-engagement fixing) is constituted by a protrusion provided on the lid main body side and a swing member provided on the inner plug side. By providing the movement regulating rocking end portion on the rocking member, it is possible to realize the posture change described so far as the rocking member rocks, and to realize the fixed control.

The characteristic configuration of the present invention is as follows:
The lid body and the inner plug are configured as a cylindrical member sharing a central axis,
When the posture is changed from the packing removal posture to the packing mounting posture, the rocking end for movement restriction of the rocking member moves in the radial direction, and the protruding portion moves in the axial direction of the central axis. There is in point to do.

  According to this configuration, when the fixed control means is configured by the movement restricting rocking end and the protruding portion, the movement of the movement restricting rocking end in the radial direction causes the portion to move between the allowable position and the restricting position. It is possible to realize interference / non-interference with the protrusions that are close to each other along the axial direction of the central axis.

The characteristic configuration of the present invention is as follows:
The lid body and the inner plug are configured as a cylindrical member sharing a central axis,
In a state where the swing member takes the packing mounting posture,
The lid body rotates around the central axis with respect to the inner plug or moves in the direction of the central axis, so that the inner plug is fixed to the lid main body.

  According to this configuration, when the fixed control means is configured by the movement restricting rocking end and the protrusion, the lid body is centered with respect to the inner plug while the movement restricting rocking end is in the allowable position. The inner plug can be fixed to the lid body by being rotated around the axis or moved in the axial direction.

The characteristic configuration of the present invention is as follows:
Regarding the fixing operation, on the distal end side in the movement direction of the lid body with respect to the inner plug,
A fixing end is provided on the tip side from the movement regulating swinging end,
By the movement, the protrusion and the fixing end are engaged.

  According to this configuration, when the fixing control means is configured by the movement restricting rocking end and the protrusion, in addition to the movement restricting rocking end, the fixing end is provided at the distal end side in the rotational movement direction of the lid body. It is possible to achieve engagement and fixation between the fixing end and the protruding portion.

The characteristic configuration of the present invention is as follows:
The lid body includes a lid main body having a screwing portion that is screwed into the container mouth portion, and an inner plug fixed to the lid main body, and a packing attaching portion to which the packing is attached. Configured for the inner plug,
In the packing removal posture, the lid main body and the inner plug are in an unfixed state in which the relative positional relationship between the two changes.

  According to this configuration, in the packing removal posture in which no packing is attached, the lid main body and the inner plug are in an unfixed state. For example, even when both are combined to some extent, the two are not fixed. Since it is in a state, the user can easily recognize this non-fixed state when assembling, and can recall forgetting to install the packing.

The characteristic configuration of the present invention is that the fixed control means unique to the present invention described above is
It is composed of a swinging member swingable around a swinging shaft provided in the inner plug, and a protrusion provided in the lid body.
The lid body and the inner plug are configured as a cylindrical member sharing a central axis,
In the packing removal posture, the lid body and the inner plug are in an unfixed state in which the relative positional relationship between the two changes, and the lid body is in the posture position of the swinging member in the packing attachment posture. The inner plug is fixed to the lid body by rotating around the central axis with respect to the inner plug.

  According to this configuration, in the packing removal posture, since the lid main body and the inner plug are in an unfixed state, it is substantially difficult for the user to enter the operation of attaching the lid. On the other hand, since the fixing between the lid main body and the inner plug can be completed in a state where the packing mounting posture is taken, it is possible to shift to the mounting of the lid accompanying the packing mounting.

As a characteristic configuration of the present invention, the lid body includes a lid body provided with a screwing portion screwed into the container mouth portion, and an inner plug fixed to the lid body, and the packing The inner plug is provided with a packing attachment portion to which is attached,
In the packing removal posture, the top surface of the lid body and the top surface of the inner plug are located at different positions, and a step may be provided between the surfaces.

  If this configuration is adopted, the user must be in a state where the packing has been removed in this situation when there is only a step between the top of the lid and the top of the plug. The cause can be investigated and solved (the packing can be attached if the packing is removed).

  As described above, it is possible to reliably install the packing for sealing the container mouth of the beverage container main body, and to obtain a beverage container that does not cause unexpected leakage or the like due to forgetting to install the packing. It was.

Embodiments of the present invention will be described with reference to the drawings.
1 to 7 are drawings of the first embodiment, and FIG. 8 is a drawing of another embodiment.

  A beverage container 100 according to the present invention includes a beverage container main body 101 and a lid 102 that is screwed onto the beverage container main body 101, and the lid 102 has the packing 10 attached to the lid 102. In the state, it can be attached to the container mouth portion 101a of the beverage container body 101, and a sealed state that prevents liquid leakage from the inside of the beverage container body 101 is realized in the attached state.

This mounting operation is performed by screwing the lid 102 to the male side screwing portion 101b provided on the outer peripheral side of the container mouth portion 101a of the beverage container main body 101.
FIG. 1 is a longitudinal sectional view in a state where the screwing operation is completed.

  As can be seen from FIG. 1, the beverage container main body 101 is provided with a container mouth portion 101 a at the upper portion thereof, and a hermetic stopper in which the smallest diameter portion of the container mouth portion 101 a is tightly sealed by the packing 10 attached to the lid 102. Part 101c. The packing 10 is a plug packing having a general annular shape.

  As can be seen from FIGS. 1 and 2, the lid body 102 includes a lid main body 20 having a female side screwing portion 20 a screwed to the male side screwing portion 101 b of the container mouth portion 101 a on the inner side surface, An inner plug 30 fixed to the lid body 20 is provided.

  The lid main body 20 is engaged with a plate holder 22 with a decoration plate 21 sandwiched between the top surface portions thereof, and the inner plug 30 is engaged and fixed therein. The lid main body top surface 22 c of the plate holder 22 becomes the “top surface” of the lid body 102 together with the top surface 32 a of the inner cap cap 32. Therefore, in the present invention, the top surface 32a of the inner cap cap 32, which is the latter, is referred to as “part of the top surface”.

  The inner plug 30 includes an inner plug body 31 and an inner plug cap 32, and the upper part of the inner plug body 31 is engaged with the lid body 20, and the packing 10 is attached to the lower part of the inner plug body 31. A mounting portion 31a is provided (see FIG. 1).

A feature of the present invention is that the lid 102 is attached to the beverage container main body 101 in the packing attachment posture in which the packing 10 is attached to the lid 102, and the sealed state is realized, and the packing 10 is removed from the lid 102. (In other words, the packing 10 is not attached) Even if the lid 102 is attached to the beverage container main body 101 in the packing removal posture, it is impossible to realize a sealed state.
In the first embodiment, corresponding to whether the inner plug 30 is fixed or not fixed to the lid main body 20, it is determined whether the sealed plug state is realized or not realized. That is, a sealed state can be realized in a fixed state in which the inner plug 30 is fixed to the lid body 20, and a sealed state cannot be realized in an unfixed state in which the inner plug 30 is not fixed to the lid body 20.

  Here, the inner plug 30 is fixed to the lid main body 20 in such a manner that the inner plug 30 contacts the lid main body 20 in the axial direction Z1 along the central axis Z, and the inner plug 30 further rotates around the central axis Z. Rotate to complete.

Hereinafter, these configurations will be described with reference to FIGS.
3 and 4 are a partial cross-sectional perspective view (FIG. 3), a vertical cross-sectional view (FIG. 4A), and a horizontal cross-sectional view (FIG. 4B) in the packing removal posture.
FIG. 4B is a bottom view when the lid 102 is viewed from the bottom side, and a cross section taken along IVa-IVa shown in FIG. 4A is shown in FIG.
In this packing removal posture, the inner plug 30 and the lid body 20 are separated in the axial direction Z1 and cannot be fixed.

FIGS. 5 and 6 are a partial cross-sectional perspective view (FIG. 5), a vertical cross-sectional view (FIG. 6A), and a horizontal cross-sectional view (FIG. 6B) in the packing mounting posture.
FIG. 6B is also a bottom view when the lid 102 is viewed from the bottom side, and a cross section of VIa-VIa shown in FIG. 6A is shown in FIG.
In this packing mounting posture, the inner plug 30 and the lid main body 20 are in contact with each other in the axial direction Z1, but in a state of waiting for a rotation operation of the central axis Z in the circumferential direction R and in a state of being relatively rotated and fixed. You can take both.
FIG. 7 is a cross-sectional view of the main part in a state where the relative rotation operation is completed and the fixing of the inner plug 30 to the lid body 20 is completed, and the vertical cross-sectional view in this state is FIG. 1 described above. .

  In these drawings, Z is a member (cover body 20, decoration plate 21, plate holder 22, inner plug 30 (inner plug body 31 and inner plug cap) that constitutes the lid 102 basically configured as a cylindrical member. 32))), Z1 is a direction along the central axis Z, D is a radial direction of the central axis Z, and R is defined around the central axis Z. When the inner stopper main body 31 is rotationally fixed, the direction in which the lid main body 20 rotates with respect to the inner stopper main body 31 is shown. 4 (b) and 6 (b) are cross-sectional views of the main part as viewed from the bottom, and are opposite to those shown in FIG.

Hereinafter, first, assembly of the common lid 102 in the packing mounting posture will be described.
As shown in FIG. 2, the lid body 102 is configured as a cylindrical member in which the lid main body 20, the inner plug body 31, and the inner plug cap 32 share a central axis Z. Further, the lid 102 is engaged with the inner plug main body 31 and the inner plug cap 32 via an intermediate inner peripheral side engaging portion 31 b provided in the inner plug main body 31, so that the upper outer peripheral side engagement provided in the inner plug main body 31 is engaged. The inner plug main body 31 and the lid main body 20 are configured to be engageable and fixed via the joint portion 31c. The upper outer peripheral engagement portion 31c is engaged with an engaged portion 20c provided on the lid body 20, and is prevented from coming off downward in the axial direction Z1.

  Here, the engagement basically secures the positional relationship in the axial direction Z1 in which both engage with each other by adjusting the relative position in the axial direction Z1 along the central axis Z, and then the relative rotation in the circumferential direction R. By moving, the engagement and fixation between the two are completed.

As described above, the inner plug 30 is fixed to the lid main body 20 by bringing the inner plug 30 into contact with the lid main body 20 in the axial direction Z1 along the central axis Z. (Axial positioning) and further rotation (circumferential positioning) around the central axis Z is realized.
In the axial positioning, in the relative phase relationship between the inner plug 30 and the lid body 30 in the circumferential direction R shown in FIGS. It moves in the axial direction Z1 using the hole 20b as a guide, and is completed by being positioned on the axial direction Z1 side (upper side in FIG. 2) from the engaged portion 20c.
Therefore, this positioning prevents the axial direction Z1 from coming off. However, as will be described later, the movement in the axial direction Z1 can be performed when the packing 10 is attached, but cannot be performed when the packing 10 is removed.
The circumferential positioning and fixing is realized by rotating the inner plug 30 from the relative phase relationship between the inner plug 30 and the lid body 20 shown in FIG. 6B to the relative phase relationship shown in FIG. With this circumferential positioning, the protrusion 23 provided on the lid main body 20 gets over the fixing end 42 of the swinging member 40 provided on the inner plug main body 31 and engages and fixes.

  As shown in FIG. 7, in the engagement and fixation, in the circumferential direction, the rotation base end side of the projecting portion 23 that hangs down from the inner peripheral surface of the lid body 20 is the fixing end portion of the swing member 40. 42, and the leading end side of the rotation is positioned by the engaged portion 20c described above with reference to FIG.

Engaging and fixing the inner plug body and the inner plug cap Since the inner plug cap 32 is made of an elastic member (for example, a silicone material), the engagement between the inner plug cap 32 and the inner plug body 31 is an axis along the central axis Z. This can be done by fitting in the direction Z1.
Specifically, the inner plug cap 32 is elastically contracted and inserted between the upper inner peripheral side engaging portions 31b provided in the insertion holes 31h of the inner plug main body 31, thereby fitting them together (a kind of engagement). ) Can be completed. As shown in FIGS. 4 and 6, the inside of the inner plug cap 32 is fitted into the inner plug main body 31, and the inside of both forms a heat insulating space 35.

Engagement and fixing of the inner cap cap to the lid body As described above, since the inner plug cap 32 is made of an elastically deformable member, the engagement and fixation of the inner plug cap 32 to the lid body 102 is performed by the lid body 102. This is performed by elastically contracting and inserting into the lid body 30 and the hole 22b (the “communication hole” of the present invention) of the plate holder 22 constituting the.

  Next, a configuration related to attachment of the lid 102 to the beverage container main body 101 corresponding to attachment / detachment of the packing 10 will be described.

As shown in FIG. 2, a swinging member 40 that can swing around a swinging axis a orthogonal to the central axis Z is provided at a predetermined phase position in the outer periphery and circumferential direction of the inner plug main body 31.
As shown in FIG. 4 (a), the swinging member 40 is located on the radially outer side of the radial direction D from the spring 45 that is a biasing member on the base end side in the axial direction Z1, which is below the swinging shaft a. Is being energized.

  As shown in FIGS. 2, 3, and 5, the swing member 40 has a movement restricting swing end 41, a fixing end 42, and a front end side in the axial direction Z <b> 1 above the swing shaft a. It has.

The cross section of the movement restricting rocking end 41 is configured to be long in the radial direction at the base end side in the circumferential direction R and short in the radial direction at the tip end side in the circumferential direction R. Accordingly, the movement restricting rocking end portion 41 has the guide inclined surface 41a positioned on the outer diameter side toward the inner diameter side and the distal end side in the circumferential direction R.
The circumferential direction R is defined around the central axis Z as described above, and the lid body 20 rotates with respect to the inner plug body 31 when the lid body 20 is rotationally fixed with respect to the inner plug body 31. Direction, which is the screwing direction when the lid body 20 is mounted (hereinafter the same).

  On the other hand, the cross section of the fixing end 42 is configured to be short in the radial direction at the base end side in the circumferential direction R and long in the radial direction at the tip end side in the circumferential direction R. Therefore, the fixing end portion 42 has a guide inclined surface 42a projecting toward the outer diameter side toward the outer diameter side and the distal end side in the circumferential direction R.

As shown in FIGS. 3 to 6, a protruding portion 23 that protrudes downward (in the side of the inner plug main body 31) is provided at a predetermined phase position in the inner periphery and circumferential direction of the lid main body 20.
The cross section of the projecting portion 23 is configured to be long in the radial direction on the circumferential direction R base end side and short in the radial direction on the circumferential direction R distal end side. As a result, the projecting portion 23 has a guide inclined surface 23a on the outer diameter side thereof.

  The swing member 40 has an intermediate approach between which the protrusion 23 can enter as the lid body 20 rotates between the movement restricting swing end 41 and the fixing end 42 described above. A portion d is provided (see FIGS. 2 and 3).

  By adopting the above configuration, in the beverage container 100 of the first embodiment, the fixing control means M is provided between the inner plug 30 and the lid body 20. In the description using FIGS. 3 to 7, the description proceeds in the process of fixing the inner plug 30 to the lid body 20. The function of the fixing control means M in this process is to attach the inner plug 30 to the lid body 20 in the packing mounting posture. This is a function that makes it possible to fix the inner plug 30 to the lid body 20 in the packing removal posture.

Hereinafter, the description will be further advanced.
The relative relationship between the inner plug 30 and the lid body 20 shown in FIGS. 3 and 4 is that “the packing removal posture” is a position (regulation position) where the movement restricting rocking end 41 is swung to the inner diameter side in the radial direction D. The relative relationship between the inner plug 30 and the lid body 20 shown in FIGS. 5 and 6 is the position at which the movement restricting oscillating end 41 is oscillated radially outward (in the retracted position with respect to the protrusion 23). Yes, which is the allowable position of the present invention).
In these figures, the circumferential direction R phase of the inner plug 30 and the lid body 20 is the same, and when the inner plug 30 is to be attached to the lid body 20, both are first guided to this relative phase.

Restricted Position In the restricted position, the movement restricting rocking end 41 is located below the protruding portion 23, and the two come into contact with each other at their heads to restrict movement in the axial direction Z <b> 1. That is, the inner plug 30 cannot sufficiently enter the lid main body 20. In the relative position in the axial direction, the upper outer peripheral side engaging portion 31c and the engaged portion 20c provided on the lid body 20 may be such that the former 31c is positioned above the latter 20c in the axial direction Z1. Therefore, the movement in the circumferential direction R is prevented between the two, and as a result, the inner plug 30 cannot be attached to the lid main body 20.

  Further, as shown in FIGS. 3 and 4A, in this state, the top surface 32a of the inner cap cap 32 takes a retracted position in which it is sunk in the axial direction Z1 with respect to the lid main body top surface 22c. In other words, a step appears and is not flush. Therefore, in this state, the user can easily know that the packing 10 is not attached.

Permissible position In the permissible position, the movement restricting rocking end 41 is retracted to the outside in the radial direction D from below the projecting portion 23, and the two do not come into contact with each other at the head and move in the axial direction Z <b> 1. Is acceptable. That is, as is apparent from a comparison between FIG. 4A and FIG. 6A, the lid main body 20 is lowered to the swing member 40 side (in other words, the inner plug 30 side) and provided on the inner plug body 31. The positioning protrusion 31d comes into contact with a predetermined part of the lid body 20.

  As shown in FIGS. 5 and 6A, in this state, the top surface 32a of the inner cap cap 32 can enter the same position as the lid main body top surface 22c. However, since the thickness in the radial direction of the projecting portion 23 is configured to be thin with respect to the intermediate entry portion d described above, the inner plug 30 still stands against the lid body 20 (between the two). A type of non-fixed state where the relative position changes). As a result, even in this state, the user can easily know that the engagement fixing of the inner plug 30 with respect to the lid body 20 is not completed.

  As described above, the fixing control means M according to the present invention includes the swinging member 40 that can swing around the swinging shaft provided in the inner plug 30 and the protrusion 23 provided in the lid body 20.

  Further, in changing the posture from the packing removal posture to the packing attachment posture, the movement restricting swing end portion 41 moves in the radial direction, and the protruding portion 23 moves close in the axial direction of the central axis Z. ing.

Fixing the inner plug to the lid body The above is the situation where the inner plug 30 enters and contacts the lid body 20. When the lid body 102 is attached to the beverage container body 101, the inner stopper 30 is fixed to the lid body 20. Need to be.
The user can fix the inner plug 30 to the lid body 20 by the fixing control means M when the user rotates the lid body 20 relative to the inner plug 30 in the circumferential direction R during this operation. The cross section of the lid body 102 is in the state shown in FIGS.

As can be seen from a comparison between FIG. 7 and FIG. 6B, the projecting portion 23 projecting downward from the lid body 20 is rotated beyond the fixed end portion 42 of the swing member 40 by this relative rotation operation. The inner plug 30 is engaged and fixed to the lid body 20 in the circumferential direction R. The axial direction Z1 is fixed by the upper outer peripheral side engaging portion 31c provided on the inner plug main body 31 described above, the engaged portion 20c provided on the lid main body 20, and the positioning protrusion provided on the inner plug main body 31. This is achieved by 31d and the lid body 20.
In this configuration, a fixing end 42 is provided on the distal end side of the movement restricting rocking end 41 on the distal end side in the rotational movement direction of the lid body 20 with respect to the inner plug 30, and the protrusion 23 is fixed by rotational movement. It is supposed that the engagement and fixing in the circumferential direction R is completed by getting over the end portion 42.
Therefore, the fixing control means M described above has the position of the swinging member 40 as the swinging member 40 swings. Is changed to a permissible position allowing position movement enabling engagement with the fixed end portion 42) and a restriction position restricting position movement allowing the protrusion 23 to engage with the swinging member 40 in the packing removal posture. The movement restricting rocking end 41 is provided. The engagement here is the engagement fixation described in this paragraph.

  The release of the engagement and fixation is realized by swinging the fixed end portion 42 from the position where the engagement and fixation can be performed (the position shown in FIG. 7) to the inner diameter side in accordance with the removal of the packing 10. Therefore, the fixing control means M of the present invention has a packing mounting posture in which the inner plug 30 is fixed to the lid body 20 by mounting the packing 10 to the packing mounting portion 31a, and the packing 10 is detached from the packing mounting portion 31a. By doing so, it has a function of making the packing removal posture in which the inner plug 30 is released from the lid body 20.
