Description

  The present invention relates to a catcher, and more particularly, to a seal structure for a catcher.

  Conventionally, interceptors have been used in kitchens of restaurants and the like. The interceptor takes in the waste water discharged from the sink (sink), removes oil components, solid components, and the like from the taken-in waste water, and discharges the waste water from which these components have been removed to the sewer.

  The interceptor usually has a structure in which an opening is formed on the upper surface and a lid that covers the opening is attached, and the rear surface of the tank is placed close to the wall in the space provided under the sink. Installed (fixed). In order for the interceptor to be detachable in the state of being installed in this way, a hook fitting such as a hinge is attached to the rear end side (that is, the side close to the wall) of the peripheral edge adjacent to the opening of the tank. The catch clip is attached to the front end side (that is, the side facing the rear end side). In this structure, a hinge fixed to the rear end side of the lid is hooked (engaged) with a hinge attached to the rear end side of the tank, and the lid is rotated around these hinges as a central axis to cover the opening. The lid is attached to the tank by bringing the catch clip attached to the front end side of the tank into a state and engaging a catch received on the front end side of the cover. Conversely, the catch clip attached to the front end of the tank releases the lid and the lid is removed from the tank by rotating the lid around the hinge attached to the rear end of the tank. Is done.

  However, the above-described conventional interceptor has the following problems. That is, first, in a state where the lid is attached to the tank, since the catch fixed to the front end side of the lid is fixed by the catch clip attached to the front end side of the tank, the front end side of the lid The torque toward the tank is sufficient. However, on the rear end side of the lid, the hinge fixed to the rear end side of the lid is only supported by a hinge attached to the rear end side of the tank. Almost no torque toward is applied. As a result, since the lid is not pressure-bonded to the tank, when the water level of the drainage stored in the tank rises, the drainage is performed between the tank and the lid around the rear end side of the tank (lid). The part may discharge water. Thus, the interceptor which concerns on the said prior art has the problem that the adhesiveness (crimpability) between a lid | cover and a tank is low.

  Furthermore, as described above, the interceptor according to the conventional technique is usually fixed in a space provided under the sink. When the space provided under the sink is narrow, that is, when the distance between the bottom surface of the sink and the top surface of the interceptor is short, the operator attaches a hinge fixed to the rear end side of the lid to the tank. When hooked on a hinge provided on the rear end side, a certain angle is formed between the lower surface of the lid and the upper surface of the tank, so that the lid blocks the operator's view. This makes it difficult for the operator to perform the operation of hooking the lid on the tank while visually confirming it when the lid is mounted on the tank. Thus, the interceptor according to the above prior art has a problem that the lid cannot be easily attached to the tank.

  The present invention has been made in view of the above-described problems, and is an obstruction capable of easily mounting the lid on the tank while improving the adhesion (crimpability) between the lid and the tank. The purpose is to provide a vessel.

  The interceptor according to the present invention includes a tank in which an opening is formed, a water stop means provided on a peripheral edge formed of an elastic material and adjacent to the opening of the tank, and a side surface adjacent to the peripheral edge of the tank. A lid that covers the opening by forming an accommodation area between the side surface by surrounding the side wall and forming an insertion port for communicating the accommodation area with the outside so as to be adjacent to the water stop means And supporting means for supporting the upper surface of the lid that has pressed the water-stopping means.

(Embodiment 1)
FIG. 1 is a perspective view showing the configuration of the interceptor according to Embodiment 1 of the present invention. 2A is a diagram showing a front surface of the interceptor shown in FIG. 1 as viewed from the direction A, and FIG. 2B is a diagram showing a side view of the interceptor shown in FIG. FIG. 2 (c) is a diagram showing an upper surface of the interceptor shown in FIG.
For convenience of explanation, FIG. 1 shows a state in which the lid 120 is removed from the tank 110 in order to show the internal configuration of the tank 110, but FIGS. 2 (a) to 2 (c). 1 shows a state in which the lid 120 shown in FIG.

  The interceptor 100 according to the present embodiment is roughly divided into a tank 110 and a lid 120.

(About the overall configuration of the tank 110)
First, the configuration of the tank 110 will be described.
As shown in FIG. 1, the tank 110 has a box shape as a whole. An opening 111 is formed on the upper surface of the tank 110, and the inside and the outside of the tank 110 communicate with each other through the opening 111.

  The tank 110 has a peripheral edge 112 extending in a substantially square shape at a position adjacent to the opening 111. On the peripheral edge 112, a packing 113 functioning as a water stop portion is extended in a substantially square shape. The packing 113 is made of an elastic material (for example, various elastic materials such as Teflon (registered trademark) and silicone).

On the back surface 110a of the tank 110, a lid pressing metal 114 that functions to press (clamp) the lid 120 is fixed by, for example, welding or screwing.
As shown in FIG. 2C, a catch clip 115 that functions to fix the lid 120 to the tank 110 is attached to the front surface 110 b of the tank 110.

  A fixing member 116 having a substantially L-shaped cross section is attached to the right side surface 110c and the left side surface 110d of the tank 110, as shown in FIGS. 1, 2 (a), and 2 (c). It has been. Each of the fixing members 116 is formed with a screw hole 116a. The tank 110 is fixed to the floor using a screw (not shown) passing through the screw hole 116a.

  As shown in FIGS. 1 and 2, an inflow port 117 is formed on the right side surface 110 c of the tank 110 to take in wastewater from a sink (not shown) into the tank 110. As shown in FIGS. 1 and 2, an outlet 118 is formed on the left side surface 110 d of the tank 110 to discharge the drainage from which oil components and solid components are removed by the tank 110 to a drainage groove (not shown).

The internal configuration of the tank 110 will be further described with reference to FIG. FIG. 3 is a cross-sectional view showing the internal configuration of the tank 110 shown in FIG. 1 along the line XX ′.
The inside of the tank 110 is roughly divided into three rooms, that is, rooms R1, R2, and R3 by partition plates 110e and 110f.

  A collecting basket 110g is arranged in the room R1. The collection basket 110g collects oil components, solid components, and the like from the wastewater taken in from the inflow port 117, and allows other components to pass therethrough. The room R1 and the room R2 are connected via a gap G1. Therefore, the waste water that has passed through the collection basket 110g flows into the room R2 through the gap G1.

  In the room R2, a partition plate 110h is provided between the partition plates 110e and 110f. This partition plate 110h is provided in order to prevent the wastewater that has flowed into the room R2 through the gap G1 from directly flowing into the room R3 through the gap G2. Even if an oil component still remains in the wastewater that has flowed into the room R2, the oil component has a specific gravity smaller than that of water, and thus rises to the vicinity of the water surface. Therefore, only the waste water excluding the oil component flows into the room R3 through the gap G2.

A trap 110i is arranged in the room R3. Trap 110i includes a cheese 110i ₁ which extends in a T-shape, cheese and UV pipe 110i ₂ attached to the lower end 110i ₁₁ of 110i _1, the upper end or lid attached to the cleaning port 110i ₁₂ cheese 110i ₁ 110i ₃ , a UV pipe 110 i ₄ attached to the right end 110 i ₁₃ of the cheese 110 i ₁ , and a socket 110 i ₅ attached between the UV pipe 110 i ₄ and the outlet 118. The waste water that has flowed into the UV pipe 110i ₂ of the trap 110i reaches the outlet 118 through the cheese 110i ₁ , the UV pipe 110i ₄ and the socket 110i ₅ , and goes out of the tank 110 through the outlet 118. Discharged.

(About the overall configuration of the lid 120)
Next, the configuration of the lid 120 will be described.
As shown in FIGS. 1 and 2, the lid 120 includes an upper surface 120a, a front surface 120b extending perpendicularly to the upper surface 120a, a right side surface 120c, and a left side surface 120d. As best shown in FIG. 1, the lid 120 has a configuration in which the back surface is opened, that is, a configuration having no back surface.

As shown in FIG. 1, for example, two handles 121 extending in a substantially U shape are attached to the upper surface 120 a of the lid 120.
As best shown in FIGS. 2A and 2C, a receiver 122 is fixed to the front surface 120 b of the lid 120. This money receiving is to engage with a catch clip 115 attached to the front face 110b of the tank 110.

(Regarding the specific configuration of the lid presser fitting 114 of the tank 110)
Next, the detailed configuration of the lid pressing metal fitting 114 of the tank 110 will be specifically described together with the configuration of the lid 120 engaged therewith.

  FIG. 4 is a cross-sectional view of the tank 110 shown in FIG. 1 taken along line YY ′. 4 shows a cross section of the lid 120 along the line ZZ ′ of the lid 120 shown in FIG. FIG. 5 is an enlarged cross-sectional view of the lid pressing metal fitting 114 shown in FIG. 4 and its periphery. FIG. 6 is an enlarged cross-sectional view showing the catch clip 115 shown in FIG. 4 and its periphery.

Referring to FIG. 5, the cover pressing metal 114 surrounds the side surface of the tank 110 (in FIG. 5, the side surface 110 </ b> L adjacent to the peripheral edge 112 among the side surfaces of the tank 110), thereby forming an accommodation region 501 with the outer surface. doing. Further, the lid pressing metal 114 forms an insertion port 502 that allows the accommodation area 501 to communicate with the outside. The insertion port 502 is formed at a position adjacent to the packing 113.
Further, the lid pressing metal 114 has an inner surface 114 a disposed at a position higher than the upper surface 113 a of the packing 113. The inner surface 114 a extends substantially parallel to the upper surface 113 a of the packing 113. The inner surface 114 a is one of the inner surfaces surrounding the accommodation area 501. The distance (distance d ₁ ) in the height direction between the inner surface 114a of the lid pressing metal fitting 114 and the upper surface 113a of the packing 113 is the thickness of one end 120E of the lid 120 (that is, the rear end 120E of the lid 120 shown in FIG. 1). Less than the thickness (thickness t ₁ ) (ie, d ₁ <t ₁ ).

One end (rear end) 120E of the lid 120 has a uniform thickness (thickness t ₁ ), that is, has a flat upper surface 120A and a lower surface 120B extending substantially parallel to each other.

  Next, referring to FIG. 6, a metal receiver 122 is fixed to the front surface 120 b of the lid 120 by, for example, welding or screwing. The receiver 122 includes a fixing portion 122a formed in a plate shape, an engaging portion 122b attached to the fixing portion 122a and having an engaging surface 122c formed in a substantially square shape, including.

  A pedestal 119 is fixed to the front surface 110 b of the tank 110, and a catch clip 115 is attached on the pedestal 119. The catch clip 115 includes a base portion 115a fixed to the pedestal 119, a rotating portion 115c rotatably attached to the base portion 115a around a central axis 115b, and a through hole 115d formed in the center of the rotating portion 115c. And an engaging portion 115e that is rotatably attached to the base and extends in a substantially square shape. According to this configuration, the catch clip 115 moves the through hole 115d upward by rotating the rotating portion 115c counterclockwise around the central axis 115b. When the through hole 115d moves upward, the engaging portion 115e attached to the through hole also moves upward. In this state, the catch clip 115 moves the through hole 115d downward by rotating the rotating portion 115c clockwise around the central axis 115b. When the through hole 115d moves downward, the engaging portion 115e attached to the through hole also moves downward.

  A method of mounting the lid 120 on the tank 110 using the lid pressing metal fitting 114 and the catch clip 115 having such a configuration will be described.

First, as shown in FIGS. 4 and 5, the operator holds the handle 121 of the lid 120 and inserts one end 120 </ b> E of the lid 120 into the accommodation region 501 through the insertion port 502 of the lid pressing metal fitting 114. Specifically, the operator can easily perform the operation by simply sliding (sliding) the lid 120 leftward on the paper surface with the lower surface 120B of the one end 120E of the lid 120 placed on the upper surface 113a of the packing 113. In addition, one end 120 </ b> E of the lid 120 can be inserted into the accommodation area 501 from the insertion port 502. Since the thickness (thickness t ₁ ) of the lid 120 is larger than the distance (distance d ₁ ) between the inner surface 114 a of the lid pressing metal fitting 114 and the upper surface 113 a of the packing 113, the thickness of the front end 120 E of the lid 120 is inevitably increased. The lower surface 120B and the upper surface 113a of the packing 113 are not parallel to each other, and a predetermined angle is generated between them (for example, about 7 degrees as shown in FIG. 5). In a state where the one end 120E of the lid 120 is housed in the accommodation area 501 and the upper surface 120A of the one end 120E faces the inner surface 114a of the lid pressing member 114, the operator lowers the lid 120 by weakening the force to support the handle 121. . Thereby, the lower surface 120C of the lid 120 is substantially parallel to the bottom surface 110E of the tank 110, that is, the opening 111 of the tank 110 is covered by the lid 120.

  In this state, as shown in FIG. 5, the lower surface 120C of the lid 120 contacts the upper surface 113a of the packing 113, and the lid 120 presses the packing 113 downward by its own weight. The packing 113 is contracted by being crimped by the lid 120. Thereby, the upper surface 120A of the one end 120E of the lid 120 comes into contact with the inner surface 114a of the lid pressing metal fitting 114. In this state, since the contracted packing 113 is formed of an elastic material, the lower surface 120C of the lid 120 is pressed upward, so the upper surface 120A of the one end 120E of the lid 120 is the inner surface 114a of the lid pressing metal fitting 114. Press. In other words, the inner surface 114a of the lid pressing metal fitting 114 abuts on the upper surface 120A of the one end 120E of the lid 120 in a state where the packing 113 is pressed to support the upper surface 120A.

  On the other hand, in the state where the opening 111 of the tank 110 is covered with the lid 120, the lower surface 120C of the other end (front end) 120F of the lid 120 also contacts the upper surface 113a of the packing 113, as shown in FIG. The lid 120 presses the packing 113 downward by its own weight. The packing 113 is contracted by being crimped by the lid 120. In this state, the metal receiver 122 attached to the front surface 120 b of the lid 120 faces the catch clip 115 attached to the front surface 110 b of the tank 110. As shown in FIG. 6, in a state where the engaging portion 115e of the catch clip 115 is engaged with (engaged with) the engaging surface 122c of the engaging portion 122b of the catch 122, the rotating portion 115c of the catch clip 115 is watched. By rotating around, the engaging portion 122b of the metal receiver 122 is pulled downward by the engaging portion 115e of the catch clip 115. Thereby, the lower surface 120C of the lid 120 further presses the packing 113 downward.

Thus, in the interceptor according to the present embodiment, the packing 113 provided on the peripheral edge 112 of the peripheral edge 112 of the tank 110 adjacent to the front surface 110b is attached to the front surface of the tank 110. Since the catch clip 115 and the catch 122 attached to the front surface 120b of the lid 120 are engaged with each other, the peripheral edge 112 of the tank 110 and the lower surface 120C of the lid 120 are sufficiently compressed. Adequate adhesion / crimpability is ensured between the peripheral edge 112 of 110 and the packing 113, and between the lower surface 120 </ b> C of the lid 120 and the packing 113.
On the other hand, of the peripheral edge 112 of the tank 110, the peripheral edge 112 adjacent to the back surface 110a is accommodated by surrounding the side surface of the tank 110 (particularly, the side surface 110L adjacent to the peripheral edge 112) by the lid pressing metal fitting 114 attached to the tank 110. A region 501 is formed, and an insertion port 502 that allows the accommodating region 501 to communicate with the outside is formed adjacent to the packing 113. Further, the lid pressing metal fitting 114 receives the lid 120 from the insertion port 502 into the accommodating area 501, and contacts the upper surface 120 </ b> A of the lid 120 in a state where the packing 113 is pressed inside the accommodating area 501. Support. As a result, the packing 113 is sufficiently compressed between the peripheral edge 112 of the tank 110 and the lower surface 120B (120C) of the lid 120, and therefore between the peripheral edge 112 of the tank 110 and the packing 113 and the lid 120. Sufficient adhesion / crimpability is ensured between the lower surface 120B (120C) and the packing 113.
In addition, since both the packing 113 provided on the periphery adjacent to the front surface 110b of the tank 110 and the packing 113 provided on the periphery adjacent to the back surface 110a are sufficiently pressure-bonded, The packing 113 provided on the periphery adjacent to each of the right side surface 110c and the left side surface 110d is also sufficiently crimped.

  Further, when the operator attaches the lid 120 to the tank 110, the operator makes one end 120 </ b> E of the lid 120 abut on the packing 113, and then the one end 120 </ b> E slides (slides) on the packing 113. ) And grip the handle 121 provided on the lid 120 so as to reach the inside of the accommodation area 501 of the lid presser fitting 114. Thereafter, the operator makes the upper surface 120A of the lid reaching the inside of the accommodation area 501 abut on the inner surface 114a of the lid pressing metal fitting 114, that is, the lower surface 120C of the lid 120 abuts on the upper surface 113a of the packing 113. Then, the handle 121 of the lid 120 is operated (the handle 121 is lowered downward according to the weight of the lid 120). As described above, the operator grips the handle 121 of the lid 120 and slides the lid 120 from the front surface 110b toward the rear surface 110a in a state of facing the front surface 110b of the tank 110, and then lowers the lid 120 downward. The lid 120 can be attached to the tank 110 by performing the operation of lowering. Since the operator can visually recognize the insertion port 502 of the lid pressing metal fitting 114 provided in the tank 110 at a position facing the front surface 110b of the tank 110, the operator visually observes the operation of mounting the lid 120 on the tank 110. It can be executed while confirming.

  Further, as shown in FIG. 5, in a state where one end 120 </ b> E of the lid 120 is inserted into the housing region 501 of the lid pressing metal fitting 114, the upper surface 120 </ b> A or the lower surface 120 </ b> B of the lid 120 and the upper surface 113 a of the packing 113. The angle formed between them is about 7 degrees (preferably 5 degrees to 10 degrees). This means that the space required above the interceptor 100 according to the present embodiment can be suppressed when the lid 120 is attached to the tank 110. That is, even when the space prepared below the sink is narrow (that is, the height of the space is small), the interceptor 100 according to the present embodiment can be disposed, and the lid 120 with respect to the tank 110 is arranged. A mounting operation can be executed.

  Thus, according to the present invention, it is possible to provide an interceptor that can easily attach the lid to the tank while improving the adhesion (crimpability) between the lid and the tank.

(Embodiment 2)
In the present embodiment, a case where the configuration of the lid pressing metal fitting 114 and the configuration of the lid 120 engaged therewith are changed in the above-described first embodiment will be described with reference to FIGS. In addition, about the same structure as the interceptor which concerns on Embodiment 1 mentioned above among the interceptors which concern on this Embodiment, the detailed description is abbreviate | omitted.

  FIG. 7 is a cross-sectional view showing the configuration of the interceptor according to Embodiment 2 of the present invention. FIG. 8 is an enlarged cross-sectional view of the lid pressing metal fitting shown in FIG. 7 and its periphery.

Referring to FIG. 8, the lid pressing metal 700 surrounds the outer surface of the tank 110 (that is, the outer surface of the packing 113 and the outer surface of the peripheral edge 112), thereby forming an accommodation region 701 between the outer surface. Further, the lid holding metal fitting 700 forms an insertion port 702 that allows the accommodation region 701 to communicate with the outside. The insertion port 702 is formed at a position adjacent to the packing 113.
Furthermore, the lid pressing metal 700 has a flat inner surface 700a that is disposed at a position higher than the upper surface 113a of the packing 113 and extends substantially parallel to the upper surface 113a. The inner surface 700 a is one of the inner surfaces surrounding the accommodation area 701.

One end (rear end) 120E of the lid 120 has an upright portion 120G that extends substantially perpendicular to the lower surface 120C of the lid 120. The upright portion 120G has a flat upper end face 120G _1. The upper end surface 120G ₁ extends substantially parallel to the lower surface 120C of the lid 120. The upper end surface 120G ₁ corresponds to one of the upper surfaces of the lid 120. The length l ₁ of the upright portion 120G is larger than the distance (distance d ₂ ) between the inner surface 700a of the lid pressing metal fitting 700 and the upper surface 113a of the packing 113 (ie, l ₁ > d ₂ ).

In the interceptor having such a configuration, as shown in FIGS. 7 and 8, the operator holds the handle 121 of the lid 120 and accommodates the one end 120 </ b> E of the lid 120 through the insertion port 702 of the lid pressing metal fitting 700. Insert into region 701. Specifically, the operator simply slides (slides) the lid 120 leftward on the paper surface with the lower surface 120C of the lid 120 placed on the upper surface 113a of the packing 113, so that the lid 120 can be easily moved. The upright portion 120 </ b> G can be inserted into the accommodation region 701 through the insertion port 702. Since the height of the insertion port 702 is smaller than the height (l ₁ ) of the upright portion 120G of the lid 120, when the upright portion 120G is passed through the insertion port 702, the lower surface 120C of the lid 120 and the packing 113 are necessarily formed. The upper surface 113a is not parallel to each other, and a predetermined angle is formed between them (for example, about 30 degrees as shown in FIG. 8).

It housed in the upright portion 120G is receiving region 701 of the cover 120, in a state in which the upper end face 120G ₁ is opposed to the inner surface 700a of the retainer member 700 cover the standing portion 120G, the operator, the lid by weakening the force to support the handle 121 120 is lowered. Thereby, the lower surface 120C of the lid 120 is substantially parallel to the bottom surface 110E of the tank 110, that is, the opening 111 of the tank 110 is covered by the lid 120. In this state, as shown in FIG. 8, the lower surface 120 </ b> C of the lid 120 is in contact with the upper surface 113 a of the packing 113, and the upper end surface 120 </ b> G ₁ of the standing portion 120 </ b> G of the lid 120 is in contact with the inner surface 700 a of the lid pressing metal 700. Since the length l ₁ of the upright portion 120G is larger than the distance (distance d ₂ ) between the inner surface 700a of the lid pressing metal fitting 700 and the upper surface 113a of the packing 113, the lower surface 120C of the lid 120 lowers the packing 113 together with its own weight. Press toward. The packing 113 is contracted by being crimped by the lid 120.

In other words, the inner surface 700a of the lid pressing fitting 700, a packing 113 to the upper end face 120G ₁ standing portion 120G of the lid 120 pressing state contact for supporting the upper end face 120G _1.

(Embodiment 3)
In the present embodiment, a case where the configuration of the lid pressing metal fitting 114 and the configuration of the lid 120 engaged therewith are changed in the above-described first embodiment will be described with reference to FIGS. 9 and 10. In addition, about the same structure as the interceptor which concerns on Embodiment 1 mentioned above among the interceptors which concern on this Embodiment, the detailed description is abbreviate | omitted.

  FIG. 9 is a cross-sectional view showing the configuration of the interceptor according to Embodiment 3 of the present invention. In FIG. 9, the expression of the handle 121 of the lid 120 is omitted. FIG. 10 is an enlarged cross-sectional view of the lid pressing metal fitting shown in FIG. 9 and its periphery.

Referring to FIG. 10, the lid pressing metal 900 surrounds the outer surface of the tank 110 (that is, the outer surface of the packing 113 and the outer surface of the peripheral edge 112), thereby forming an accommodation region 901 between the outer surface. Further, the lid pressing metal 900 forms an insertion port 902 that allows the accommodation area 901 to communicate with the outside. The insertion port 902 is formed at a position adjacent to the packing 113. Further, the lid pressing metal 900 has a flat end surface 900a that is disposed at a position lower than the upper surface 113a of the packing 113 and extends substantially parallel to the upper surface 113a.
One end (rear end) 120E of the lid 120 includes a connecting portion 120H extending in a direction intersecting the lower surface 120C of the lid 120, and an engaging portion 120I extending substantially perpendicular to the connecting portion 120H.

In the interceptor having such a configuration, as shown in FIGS. 9 and 10, the operator first holds a handle 121 (not shown) of the lid 120 and then lowers the lower surface 120I of the engaging portion 120I. _The lid 120 is moved so that ₁ faces the insertion port 902 of the lid pressing metal 900 (position P ₁ ).
Next, the operator lowers the lid 120 downward (position P ₂ ) so that the lower surface 120C of the one end 120E of the lid 120 contacts the packing 113. At this time, the end surface 120I ₃ of the engaging portion 120I faces the inner surface 900b of the lid pressing metal 900. In this state, an angle of about 10 degrees is formed between the lower surface 120C of the lid 120 and the upper surface 113a of the packing 113.
Further, to the end surface 120I ₃ of the engaging portion 120I comes into contact with the inner surface 900b of the lid retainer member 900, the operator, after pushed (i.e. the paper surface on the left) the lid 120 in the forward direction, the lower surface of the lid 120 120C The operator lowers the lid 120 downward (position P ₃ ) so as to contact the upper surface 113a of the packing 113. Thereby, the opening 111 of the tank 110 is covered with the lid 120. In this state, as shown in FIG. 10, the lower surface 120 </ b> C of the lid 120 contacts the upper surface 113 a of the packing 113, and the upper surface 120 </ b> I ₂ of the engagement portion 120 </ b> I of the lid 120 contacts the end surface 900 a of the lid pressing metal 900.
Here, the lower surface of the lid 120 in a state where the upper surface 120I ₂ of the engaging portion 120I is in contact with the end surface 900a of the lid pressing metal 900 and the end surface 120I ₃ of the engaging portion 120I is in contact with the inner surface 900b of the lid pressing metal 900. The distance between 120 C and the upper surface 112 a of the peripheral edge 112 is smaller than the thickness of the packing 113. Accordingly, the lower surface 120C of the lid 120 presses the packing 113 downward together with its own weight. The packing 113 is contracted by being crimped by the lid 120. In this state, the packing 113 deflated, by being formed of an elastic material, so to press the lower surface 120C of the lid 120 upward, pressing the upper surface 120I ₂ lid engaging portion 120I of the lid 120 fitting 900 The end surface 900a of the first press is pressed. In other words, the end face 900a of the lid pressing bracket 900, the upper surface 120I ₂ engaging portion 120I of the lid 120 in the state of pressing the packing 113 abuts to support the upper surface 120I _2.
