Description

The present invention relates to a pipe joint for a temporary toilet capable of connecting a vertical pipe buried in the ground and a temporary toilet.

Conventionally, there has been known a temporary toilet that can be connected to a standing pipe (for example, an outdoor manhole or a standing pipe) buried in the ground in advance after the fact. By installing a temporary toilet above the vertical pipe buried in the ground and connecting this temporary toilet to the vertical pipe, the existing vertical pipe can be used as a sewage pipe of the temporary toilet. As a result, in the event of a disaster or the like, a temporary toilet can be installed by diverting the existing standing pipe. For example, Patent Documents 1 and 2 disclose such temporary toilets.

Before installing the temporary toilet, the lid is fitted in the lid frame fixed to the upper end of the standing pipe, but when installing the temporary toilet, it is necessary to connect the temporary toilet and the standing pipe by piping. Patent Document 1 describes a method of connecting a temporary toilet and a standing pipe by forming a through hole in a lid and inserting a drainage pipe of the temporary toilet through the through hole. In Patent Document 2, instead of the lid, a joint having a flange portion fitted to the lid frame is attached to the lid frame, and the discharge pipe of the temporary toilet is connected to the joint to connect the temporary toilet and the standing pipe. How to do it is described.

The pipe joint for a temporary toilet according to the present invention connects a pipe line having a standing pipe buried in the ground and a lid frame fitted to the standing pipe, and a temporary toilet installed above the pipe line. The temporary toilet pipe joint is provided with a closing plate portion that is detachably supported by the lid frame and a tubular portion that penetrates the closing plate portion. A connection port to which the temporary toilet can be connected is formed in the upper part of the cylinder portion. When the lid is fitted into the lid frame, it is configured to be arranged below the lid.

In the temporary toilet pipe joint, a standing pipe is constructed, the lid frame is fitted to the standing pipe, and then the closing plate portion is supported by the lid frame. Then, the lid is fitted into the lid frame. As a result, the pipe joint for the temporary toilet is housed inside the standing pipe. When installing a temporary toilet, such as in the event of a disaster, remove the lid from the lid frame and connect the temporary toilet to the connection port of the cylinder. As a result, the temporary toilet and the standing pipe can be connected. In addition, "connecting a temporary toilet to the connection port of the cylinder" here means that the temporary toilet is directly connected to the connection port of the cylinder, or indirectly by using another member such as a pipe or a pipe joint. Includes both when connecting to and. According to the temporary toilet fitting, it is placed below the lid (in other words, inside the standing pipe) in advance, so it is necessary to carry it from the warehouse to the installation site when installing the temporary toilet in the event of a disaster. No. Further, the temporary toilet and the standing pipe can be connected only by connecting the temporary toilet to the connection port of the tubular portion. Therefore, even an unskilled worker can quickly and effortlessly connect the vertical pipe and the temporary toilet.

By the way, the vertical pipe is used as a sewage pipe for a temporary toilet when installing a temporary toilet, but normally (that is, before installing the temporary toilet), a manhole connected to a sewer main, or sewage. It is used as a pipe for inspecting pipes from the ground. The pipe joint for the temporary toilet is arranged below the lid before the installation of the temporary toilet, but since it is removable from the lid frame, it can be easily removed from the lid frame at the time of inspection. Therefore, it does not interfere with the inspection and the normal inspection is easy.

According to a preferred aspect of the present invention, the lid frame has a tubular portion, a lid fitting portion into which the lid is detachably fitted, and a radial direction from the tubular portion below the lid fitting portion. It has an annular portion that protrudes inward. The closing plate portion is configured to be placed on the annular portion without being fixed to the lid frame when the lid is fitted in the lid frame.

According to the above aspect, the temporary toilet pipe joint can be supported by the lid frame only by placing the closing plate portion on the annular portion of the lid frame. It is easy to attach / detach the pipe joint for temporary toilets to / from the lid frame. Therefore, the temporary toilet pipe joint can be easily installed at the time of construction of the vertical pipe, as compared with the case where the temporary toilet pipe joint is detachably fixed to the lid frame with bolts or the like. In addition, the temporary toilet fitting can be easily removed from the lid frame at the time of inspection.

According to a preferred embodiment of the present invention, the temporary toilet pipe joint includes a deodorant valve detachably connected to the closing plate portion or the cylinder portion. The term "connected" as used herein includes both a case of being directly connected and a case of being indirectly connected via another member.

According to the above aspect, when a temporary toilet not provided with a deodorant valve is connected, the deodorant valve can prevent the odor from leaking to the outside. On the other hand, since the deodorant valve is removable, when a temporary toilet provided with the deodorant valve is connected, it is possible to prevent the deodorant valves from being installed in duplicate by removing the deodorant valve.

According to a preferred aspect of the present invention, the temporary toilet pipe joint includes a seal member provided on the peripheral edge of the lower surface of the closing plate portion.

According to the above aspect, the sealing member enhances the adhesion between the closing plate portion and the annular portion of the lid frame. Therefore, it is possible to more reliably prevent the odor from leaking from the gap between the closing plate portion and the annular portion of the lid frame.

According to a preferred aspect of the present invention, the temporary toilet pipe joint includes a string-shaped member attachment portion to which a string-shaped member connected to the lid is attached.

According to the above aspect, the lid and the pipe joint for the temporary toilet can be connected by the string-shaped member. The lid remains removed from the lid frame during the period of use of the temporary toilet. However, since the lid is connected to the pipe joint for the temporary toilet by a string-shaped member, it is possible to prevent the lid from being lost.

According to the present invention, there is provided a pipe joint for a temporary toilet capable of connecting a vertical pipe buried in the ground and a temporary toilet quickly and without hassle even by an unskilled worker. be able to.

It is a bottom view of the pipe joint for the temporary toilet. It is a vertical cross-sectional view when the said pipe joint for a temporary toilet is housed in the standing pipe. It is a vertical cross-sectional view when the pipe joint for the temporary toilet is connected to the temporary toilet. It is a figure which shows the state which installed the temporary toilet which does not have a built-in deodorant valve. It is a side view at the time of removing the deodorant valve of the pipe joint for the temporary toilet. It is a figure which shows the state which installed the temporary toilet with a built-in deodorant valve.

Hereinafter, an embodiment of a temporary toilet fitting (hereinafter referred to as a fitting) according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of the pipe joint 1. FIG. 2 is a plan view of the pipe joint 1. FIG. 3 is a bottom view of the pipe joint 1. FIG. 4 is a vertical cross-sectional view when the pipe joint 1 is housed inside a standing pipe 7 buried in the ground.

As shown in FIGS. 1 to 3, the pipe joint 1 is a deodorizing valve detachably connected to the closing plate portion 2, the cylinder portion 3 penetrating the closing plate portion 2, and the closing plate portion 2 or the cylinder portion 3. It has 4.

The shape of the closing plate portion 2 is not particularly limited, but in the present embodiment, it is formed in a disk shape. An annular sealing member 5 is attached to the peripheral edge of the lower surface of the closing plate portion 2 (see FIG. 3). The material of the sealing member 5 is not particularly limited, but is, for example, rubber. As the seal member 5, for example, a rubber seal ring can be used.

The shape of the tubular portion 3 is not particularly limited, but in the present embodiment, it is formed in a cylindrical shape. A connection port 3a formed of a receiving port is formed on the upper portion of the tubular portion 3. However, the connection port 3a is not limited to the receiving port, and may be an outlet. The shape of the tubular portion 3 is not limited to the cylindrical shape.

The closing plate portion 2 and the cylinder portion 3 may be separate bodies, but may be integrally molded. In the present embodiment, the closing plate portion 2 and the cylinder portion 3 are integrally molded. The materials of the closing plate portion 2 and the cylinder portion 3 are not particularly limited, but in the present embodiment, they are made of synthetic resin.

The deodorant valve 4 has an arm 4a extending downward, a valve body 4b, a support shaft 4c that swingably supports the valve body 4b on the arm 4a, and a weight 4d. The arm 4a is formed in an L shape and is detachably connected to the closing plate portion 2 by a bolt 15. However, the method of connecting the arm 4a to the closing plate portion 2 is not limited at all. Further, in the present embodiment, the deodorant valve 4 is detachably connected to the closing plate portion 2, but the deodorant valve 4 may be detachably connected to the cylinder portion 3. As shown in FIG. 3, the weight 4d is connected to the valve body 4b. The weight 4d may be separate from the valve body 4b, or may be integrally molded with the valve body 4b. In this embodiment, the weight 4d is integrally molded with the valve body 4b. As shown in FIG. 3, the weight 4d is arranged on the side opposite to the valve body 4b with respect to the axis 4f of the support shaft 4c. In FIG. 3, the valve body 4b is arranged on the right side of the axis 4f, and the weight 4d is arranged on the left side of the axis 4f. Since the weight of the weight 4d is larger than the weight of the valve body 4b, an upward force acts on the valve body 4b around the axis 4f in a state where sewage is not accumulated on the valve body 4b. Therefore, as shown in FIGS. 1 and 4, the valve body 4b is in a closed state. On the other hand, when sewage collects on the valve body 4b and the weight of the sewage and the valve body 4b becomes larger than the weight of the weight 4d, the valve body 4b rotates downward around the axis 4f. As a result, as shown in FIG. 5, the valve body 4b is opened.

The valve body 4b is configured to open and close the lower opening of the tubular portion 3. A rubber ring 6 is attached to the lower end surface of the tubular portion 3 (see FIG. 5). When the valve body 4b is closed, the rubber ring 6 is interposed between the valve body 4b and the lower end surface of the tubular portion 3 (see FIG. 4). The rubber ring 6 improves the sealing property when the valve body 4b is closed. However, the rubber ring 6 is not always necessary and can be omitted. The rubber ring 6 may be attached to the valve body 4b. It is also possible to use a sealing member other than the rubber ring 6.

The above is the configuration of the pipe joint 1. The pipe joint 1 is a member that connects a pipe line 10 having a standing pipe 7 buried in the ground and a lid frame 8 fitted to the standing pipe 7 and a temporary toilet installed above the pipe line 10. However, as shown in FIG. 4, before the temporary toilet is installed, it is housed inside the vertical pipe 7.

The vertical pipe 7 is a pipe buried in the ground and extending vertically. The vertical pipe 7 is, for example, a manhole, a vertical pipe, or the like. Although not shown, the lower end of the standing pipe 7 is connected to a manhole, a sewage pipe, or the like connected to the sewage main. The material of the standing pipe 7 is not limited in any way, and is, for example, concrete, synthetic resin, or the like.

As shown in FIG. 4, the lid frame 8 has a tubular portion 8a, a lid fitting portion 8b into which the lid 11 is detachably fitted, and a radial inside from the tubular portion 8a below the lid fitting portion 8b. It has an annular portion 8c protruding into the shape.

The pipe joint 1 and the lid 11 are connected by a chain 12. Here, a mounting portion 9 projecting upward is formed on the closing plate portion 2 of the pipe joint 1. A hole 9a is formed in the mounting portion 9, and one end of the chain 12 is locked in the hole 9a. The lid 11 is formed with a mounting portion 11a that projects downward. The other end of the chain 12 is locked in the hole 11b of the mounting portion 11a. The chain 12 is an example of a string-shaped member. The string-shaped member is a long member that is easily deformed. However, the string-shaped member is not limited to the chain 12, and may be a belt, a string, a wire, or the like. In the drawings other than FIG. 4, the mounting portion 9 and the chain 12 are not shown.

As shown in FIG. 4, when the lid 11 is fitted in the lid frame 8, the pipe joint 1 is arranged below the lid 11. The pipe joint 1 is arranged at a position lower than the ground surface GL. The pipe joint 1 is housed inside the standing pipe 7. The pipe joint 1 is detachably supported by the lid frame 8. The pipe joint 1 may be fixed to the lid frame 8 with screws or the like, but in the present embodiment, the pipe joint 1 is not fixed to the lid frame 8 and the closing plate portion 2 is an annular shape of the lid frame 8. It is supported by the lid frame 8 by being placed on the portion 8c. The pipe joint 1 can be easily attached to the lid frame 8 simply by placing the closing plate portion 2 on the annular portion 8c of the lid frame 8. On the contrary, the pipe joint 1 can be easily removed from the lid frame 8 simply by lifting the pipe joint 1.

When the closing plate portion 2 is placed on the annular portion 8c, the sealing member 5 is interposed between the closing plate portion 2 and the annular portion 8c. The seal member 5 closes the gap between the closing plate portion 2 and the annular portion 8c. The gap between the pipe joint 1 and the lid frame 8 is closed, and good sealing performance is maintained.

As shown in FIG. 4, the closing plate portion 2 may be provided with a protrusion 2a having an outer peripheral surface that contacts the inner peripheral surface of the annular portion 8c of the lid frame 8. The closing plate portion 2 is in contact with the lower surface portion that contacts the upper surface of the annular portion 8c via the seal member 5 and the inner peripheral surface of the annular portion 8c (may be in direct contact, or is in contact via the seal member). A stepped portion having an outer peripheral surface may be provided.

Since the pipe joint 1 can be housed in the standing pipe 7, it can be installed at the same time as the standing pipe 7 is constructed. For example, after the standing pipe 7 is constructed, the lid frame 8 is fitted into the upper end of the standing pipe 7. Then, the pipe joint 1 is attached to the lid frame 8, and the lid 11 is fitted into the lid frame 8. As a result, the pipe joint 1 can be housed inside the standing pipe 7 in advance. By accommodating the pipe joint 1 inside the standing pipe 7 in advance, it is not necessary to bring the pipe joint 1 to the installation site when installing a temporary toilet in the event of a disaster or the like.

Next, an example of how to install a temporary toilet will be described. In the present embodiment, either a temporary toilet having no built-in deodorant valve or a temporary toilet having a built-in deodorant valve can be connected to the pipeline 10. The configuration of the temporary toilet is not particularly limited.

First, a method of connecting a temporary toilet without a built-in deodorant valve will be described. When installing a temporary toilet, first, the lid 11 is removed from the lid frame 8. Next, as shown in FIG. 6, a temporary toilet 20 is installed above the lid frame 8 and the standing pipe 7, and the temporary toilet 20 is connected to the connection port 3a of the pipe joint 1 (see FIG. 5). The term "connecting the temporary toilet 20" as used herein includes both a case where the discharge portion of the temporary toilet 20 is directly connected and a case where the temporary toilet 20 is indirectly connected via a pipe or a pipe joint.

Although not shown in FIG. 6, the lid 11 is connected to the pipe joint 1 by a chain 12 (see FIG. 4). The lid 11 stays in the vicinity of the temporary toilet 20 while being connected to the chain 12. Therefore, it is possible to prevent the lid 11 from being lost after the temporary toilet 20 is installed. However, if the lid 11 is an obstacle, the chain 12 can be removed and the lid 11 can be moved to another place.

The specific configuration of the temporary toilet 20 is not limited in any way, but the temporary toilet 20 according to the present embodiment includes a bowl 21 constituting a toilet bowl, a water supply tank 22 for storing water, and a frame for supporting the bowl 21 and the water supply tank 22. It is equipped with 23.

Since the temporary toilet 20 is not provided with a deodorant valve, the configuration is simple. In addition, there is an advantage that the size and weight can be reduced. However, the temporary toilet 20 itself cannot prevent the odor from leaking to the outside. However, according to the present embodiment, since the pipe joint 1 provided with the deodorizing valve 4 is interposed between the temporary toilet 20 and the standing pipe 7, it is possible to prevent the odor from leaking to the outside.

Next, a method of connecting a temporary toilet having a built-in deodorant valve will be described. In this case as well, first, the lid 11 is removed from the lid frame 8. When installing a temporary toilet with a built-in deodorant valve, the deodorant valve 4 of the pipe joint 1 is unnecessary. Therefore, next, the pipe joint 1 is removed from the lid frame 8, the bolt 15 is removed, and the deodorant valve 4 is removed from the closing plate portion 2 (see FIG. 7). Then, the pipe joint 1 from which the deodorant valve 4 has been removed is attached to the lid frame 8. As described above, in the present embodiment, the pipe joint 1 is only mounted on the annular portion 8c of the lid frame 8, so that the pipe joint 1 can be easily removed from the lid frame 8 simply by lifting the pipe joint 1. The pipe joint 1 can be easily attached to the lid frame 8 simply by placing the closing plate portion 2 on the annular portion 8c of the lid frame 8. Next, as shown in FIG. 8, the temporary toilet 30 is installed above the lid frame 8 and the standing pipe 7, and the temporary toilet 30 is connected to the connection port 3a of the pipe joint 1. If the bolt hole of the closing plate 2 (the hole into which the bolt 15 for attaching the deodorant valve 4 was inserted) is left open, odor will leak to the outside through this bolt hole, so the bolt hole is the bolt 15 or another. It is preferable to seal with the sealing member of.

Although not shown in FIG. 8, as described above, the lid 11 is connected to the pipe joint 1 by a chain 12 (see FIG. 4). Therefore, it is possible to prevent the lid 11 from being lost after the temporary toilet 30 is installed.

The specific configuration of the temporary toilet 30 is not limited in any way, but here, the temporary toilet 30 includes a bowl 31 constituting a toilet bowl, a deodorant valve 34 provided at the lower part of the bowl 31, a water supply tank 32 for storing water, and the like. It includes a bowl 31 and a frame 33 that supports the water supply tank 32.

As described above, according to the present embodiment, when the temporary toilet 20 is installed, the temporary toilet 20 is connected to the connection port 3a of the pipe joint 1 by removing the lid 11 from the lid frame 8. 20 and the standing pipe 7 can be connected. Since the pipe joint 1 is arranged in advance below the lid 11 (in other words, inside the standing pipe 7), it is not necessary to carry it from the warehouse or the like to the installation site when installing the temporary toilet 20 in the event of a disaster or the like. Further, it is not necessary to form a through hole in the lid 11 at the installation site, and the temporary toilet 20 and the standing pipe 7 can be connected only by connecting the temporary toilet 20 to the connection port 3a of the tubular portion 3. .. Therefore, even an unskilled worker can quickly and effortlessly connect the vertical pipe 7 and the temporary toilet 20.

By the way, the standing pipe 7 is used as a sewage pipe for a temporary toilet when the temporary toilet 20 is installed, but in normal times (that is, before the installation of the temporary toilet 20), a manhole connected to the sewer main is used. , Or used as a pipe for inspecting sewage pipes, etc. from the ground. The pipe joint 1 according to the present embodiment is arranged below the lid 11 before the temporary toilet 20 is installed, but is detachable from the lid frame 8. Therefore, it can be easily removed from the lid frame 8 at the time of inspection. Therefore, it does not interfere with the inspection and the normal inspection is easy.

Further, according to the present embodiment, the pipe joint 1 is supported by the lid frame 8 by mounting the closing plate portion 2 without being fixed to the annular portion 8c of the lid frame 8. Therefore, the pipe joint 1 can be easily attached to the lid frame 8 simply by placing the closing plate portion 2 on the annular portion 8c of the lid frame 8. According to this embodiment, the pipe joint 1 can be easily attached to and detached from the lid frame 8. Therefore, the pipe joint 1 can be easily installed when the vertical pipe 7 is constructed. Further, the pipe joint 1 can be easily removed from the lid frame 8 at the time of inspection.

Further, according to the present embodiment, the pipe joint 1 is provided with a removable deodorant valve 4. When a temporary toilet 20 not provided with a deodorant valve is connected, the deodorant valve 4 can prevent the odor from leaking to the outside. On the other hand, when a temporary toilet 30 provided with a deodorant valve 34 is connected, it is possible to prevent the deodorant valves from being installed in duplicate by removing the deodorant valve 4. According to the present embodiment, regardless of whether the temporary toilet 20 having no built-in deodorant valve or the temporary toilet 30 having a built-in deodorant valve is installed, the existing standing pipe 7 buried in the ground is used for the temporary toilet. It can be used as a sewage pipe. Therefore, at the construction stage of the standing pipe 7, the standing pipe 7 can be prepared so that it can be used for both temporary toilets 20 and 30.

By the way, in the present embodiment, at least the closing plate portion 2 and the tubular portion 3 of the pipe joint 1 are made of synthetic resin. The pipe joint 1 is lighter than the case where the closing plate portion 2 and the cylinder portion 3 are made of metal. When the weight of the pipe joint 1 is small, the pressure between the closing plate portion 2 and the annular portion 8c of the lid frame 8 is relatively small, so that the sealing property between the pipe joint 1 and the lid frame 8 is lowered. The odor may leak to the outside. However, the pipe joint 1 according to the present embodiment includes a weight 4d. Therefore, the weight of the pipe joint 1 can be increased, and the adhesion between the closing plate portion 2 and the annular portion 8c of the lid frame 8 can be enhanced. Therefore, the sealing property between the pipe joint 1 and the lid frame 8 can be enhanced, and the leakage of odor to the outside can be prevented more reliably.

The weight 4d according to the present embodiment is originally a weight that gives a force in the closing direction to the valve body 4b of the deodorant valve 4. After the valve body 4b of the deodorant valve 4 is opened by the weight 4d and the sewage accumulated on the valve body 4b is discharged, the valve body 4b is automatically closed. According to the present embodiment, the weight 4d for closing the valve body 4b can be diverted as the weight for improving the sealing property.

Further, in the present embodiment, the seal member 5 is provided on the peripheral edge of the lower surface of the closing plate portion 2 of the pipe joint 1. With this sealing member 5, the adhesion between the closing plate portion 2 and the annular portion 8c of the lid frame 8 can be enhanced, and the sealing property can be improved. Therefore, it is possible to more reliably prevent the odor from leaking to the outside. It is desirable that the seal member 5 is made of an elastic material. When the seal member 5 is crushed by the weight of the pipe joint 1 other than the seal member 5 and brought into close contact with the closing plate portion 2 and the annular portion 8c of the lid frame 8, deodorization can be achieved more reliably.

In the present embodiment, the pipe joint 1 includes a mounting portion 9 for attaching the chain 12. The pipe joint 1 and the lid 11 are connected by a chain 12. Therefore, the lid 11 is removed from the lid frame 8 when the temporary toilet 20 is installed, but it is possible to prevent the lid 11 from being lost during the period of use of the temporary toilet 20. However, the chain 12 and the mounting portion 9 are not always necessary. The pipe joint 1 and the lid 11 do not have to be connected.

Although one embodiment of the present invention has been described above, it goes without saying that the embodiment of the present invention is not limited to the above-described embodiment.

In the above embodiment, before the temporary toilets 20 and 30 are installed, the pipe joint 1 is housed inside the standing pipe 7 with the deodorant valve 4 attached (see FIG. 1). However, it is also possible to accommodate the pipe joint 1 inside the standing pipe 7 with the deodorant valve 4 removed (see FIG. 7). In this case, when installing the temporary toilet 30 having the deodorant valve 34 built-in, the temporary toilet 30 can be connected to the connection port 3a immediately after the lid 11 is removed. On the other hand, when installing a temporary toilet 20 without a built-in deodorant valve, the pipe joint 1 is temporarily removed from the lid frame 8 after the lid 11 is removed. Next, the deodorant valve 4 is connected to the closing plate portion 2, and the pipe joint 1 is attached to the lid frame 8. Then, the temporary toilet 20 is connected to the connection port 3a of the pipe joint 1.

The temporary toilet pipe joint 1 according to the embodiment includes a removable deodorant valve 4, but the temporary toilet pipe joint according to the present invention does not necessarily have to be provided with a deodorant valve. The pipe joint for a temporary toilet does not have to have a structure for attaching a deodorant valve (for example, a bolt hole into which the above-mentioned bolt 15 is inserted).

The inner peripheral surface of the connection port 3a may be a smooth surface or may have a spiral groove. That is, the connection port 3a may be configured such that the pipe member is slidable or screwable. The connection port 3a may be a so-called adhesive port or a rubber ring port, may be various outlets, and may have a screw structure (bag nut or the like).

When the deodorant valve 4 is removed, another pipe may or may not be connected to the lower side of the tubular portion 3. The lower portion of the tubular portion 3 may have various pipe connection structures as described above.

In the above embodiment, the temporary toilets 20 and 30 are installed directly above the pipeline 10, but the installation positions of the temporary toilets 20 and 30 are not limited. The temporary toilets 20 and 30 are installed above the pipeline 10, but the term "installed above the pipeline 10" means that the temporary toilets 20 and 30 are installed at a position higher than the pipeline 10. Means.

The sealing member 5 improves the sealing property between the pipe joint 1 and the lid frame 8 in order to prevent odor from leaking to the outside, but the arrangement thereof is not particularly limited. In the above embodiment, the seal member 5 is provided on the peripheral edge of the lower surface of the closing plate portion 2, and is arranged between the lower surface of the closing plate portion 2 and the upper surface of the annular portion 8c of the lid frame 8. However, it is not particularly limited, and other arrangements are possible. For example, the seal member 5 may be provided on the peripheral edge of the closing plate portion 2, and the sealing member 5 may be interposed between the peripheral edge of the closing plate portion 2 and the inner wall of the tubular portion 8a of the lid frame 8.
