Description

  The present invention relates to a bag, and more particularly, to a bag having, for example, a bag body having an inspection port and a lid that is detachably attached to the inspection port via a seal member.

An example of this type of conventional bag is disclosed in Patent Document 1. The technology of Patent Document 1 is a synthetic resin aggregate cage provided with a partition in the interior of the cage body. A lid is detachably attached to a lid fitting opening formed in the upper part of the main body in a state of being completely sealed by a lip-shaped packing (seal member). The lid is attached by using a bayonet connection between a locking rod protruding from the upper edge of the rod body and a flange formed on the lid.
Japanese Patent No. 3791770 [E03F 5/10]

  When a lid is attached to the bag body, a sealing member such as an O-ring is used so that odors in the bag do not leak to the outside. In addition, it is necessary to prevent the lid from being inadvertently removed when the pressure in the cage rises, so not only simply fitting the lid into the bag body, but also bayonet coupling or screw coupling, A method of fixing by turning the lid is often employed.

  The seal member usually has its frictional resistance lowered by applying a lubricant or the like, but the lubricant is dried and does not function over time, and the seal member may be compressed and fixed. is there. In the technique of Patent Document 1, since it is necessary to remove the lid by rotating the lid itself, that is, rotating the seal member in the circumferential direction, it is very difficult to remove the lid when the seal member is in a fixed state. It becomes difficult. In a cage installed in a large space, it is conceivable to use a turning jig to turn the lid. However, if the cage is installed in a narrow place such as under the floor, the turning jig cannot be used. In addition, in order to use a turning jig under the floor or the like, there is a restriction that an inspection port must be provided in the floor and a ridge must be installed under the inspection port.

  Therefore, the main object of the present invention is to provide a novel bag.

  Another object of the present invention is to provide a scissors that can be easily removed even when the sealing member is in a fixed state.

  The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses and supplementary explanations indicate correspondence with embodiments described later in order to help understanding of the present invention, and do not limit the present invention.

  1st invention is provided with the presser member which presses a lid in cooperation with a coffin main body, in a coffin which has a coffin main body which has an inspection port, and a lid which can be detachably attached to an inspection port via a seal member It is a cocoon characterized by.

  In the first invention, the gutter (10) is installed, for example, under the floor (100) of a detached house or the like, and discharges the drainage branch pipe (102) through which drainage from housing equipment flows and the drainage to the outside. The drainage main pipe (106) to be connected is connected. The scissors include a scissors body (12) having an inspection port (24), and a lid (14) is airtightly and watertightly attached to the inspection port via a seal member (68). The pressing member (16) is attached to the heel body using, for example, bayonet coupling, and presses the lid in cooperation with the heel body. Since the presser member holds the lid, it is not necessary to use a method of rotating and fixing the lid, such as bayonet coupling, to prevent the lid from being inadvertently detached from the bag body, and the lid is simply fitted into the inspection port, for example. Just get better.

  According to the first invention, when removing the lid, it is not necessary to rotate the lid in the circumferential direction, so that the lid can be easily removed even when the seal member is in a fixed state.

  A second invention is dependent on the first invention, the lid has a vent hole that allows the inside of the bag body to communicate with the outside air, and the pressing member covers the vent hole with a predetermined space therebetween.

  In the second invention, the lid (14) has a vent hole (116) for communicating the inside of the bag main body (12) with the outside air. For example, a one vent valve (110) is provided inside the lid, and when negative pressure is generated in the bag main body, air flows through the vent hole. The pressing member (16) covers the vent hole with a predetermined space (126, 128) therebetween. This makes it difficult for foreign matter such as dust to accumulate on the upper surface of the lid around the vent hole. For this reason, when air flows in from the vent hole, dust and the like are not sucked at the same time, and the sealing performance of the vent valve can be ensured.

  According to the present invention, the lid can be easily removed from the inspection port of the bag main body even when the seal member is in a fixed state.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  With reference to FIG. 1 and FIG. 2, the gutter 10 which is one Example of this invention is arrange | positioned under floors 100, such as a detached house, and the domestic waste_water | drain discharged | emitted from residential equipment, such as a toilet and a bath, This is a junction that connects a plurality of drainage branch pipes 102 to flow and a drainage main pipe 106 that passes through the foundation 104 and discharges domestic wastewater to the outside. The heel 10 is formed of a synthetic resin such as vinyl chloride, and includes a heel body 12, a lid 14, and a pressing member 16 for pressing the lid 14.

  As shown in FIG. 3, the bag main body 12 is formed by injection molding or the like, and includes a substantially cylindrical side wall portion 20. The inner diameter of the side wall part 20 is 155 mm, for example. The upper end 22 of the side wall 20 is open, and the upper end opening is used as the inspection port 24. A lid 14, which will be described in detail later, is detachably attached to the inspection port 24. In addition, four first claw portions 26 projecting outward are formed at the upper end 22 of the side wall portion 20.

  Moreover, one side of the side wall part 20 is dented inward, and the level | step-difference part 28 is formed there. Each of the upper portions on both side ends of the step portion 28 has a step shape, and a first support portion 30 is formed there, and a second support that protrudes in an arc shape so as to connect the horizontal surfaces of the first support portion 30 to each other. Part 32 is formed.

  An inflow portion 34 is provided on each of the three sides excluding the stepped portion 28 side of the side wall portion 20 so as to protrude outward. The inflow portion 34 is an inflow port through which drainage from the drainage branch pipe 102 flows, and is also a connection portion connected to the drainage branch pipe 102 by adhesive bonding or the like. In this embodiment, three inflow portions 34 are provided, and drainage from the three drainage branch pipes 102 can flow in (join). The inflow portion 34 is formed in a cylindrical shape having a receiving structure, and has an inner diameter of, for example, 90 mm.

  Further, a tapered bottom wall portion 36 (see FIG. 2) is formed in the lower portion of the side wall portion 20, and the upper surface of the bottom wall portion 36, that is, the bottom surface of the bag main body 12 is inclined downward toward the center direction. A cylindrical outflow portion 38 is formed extending downward in the center of the bottom wall portion 36. The outflow portion 38 is an outflow port through which drainage flows out to the drainage main pipe 106 and is also a connection portion connected to the drainage main pipe 106 by adhesive bonding or the like. The outer diameter of the outflow portion 38 is, for example, 106 mm, and the height thereof is, for example, 40 mm.

  Moreover, the partition 40 as shown in FIG. 4 may be provided in the inside of the bag main body 12 so that attachment or detachment is possible. However, it is not always necessary to provide the partition body 40 in the bag main body 12, and the partition body 40 may not be provided, and the configuration thereof will be described later.

  A lid 14 is detachably attached to the inspection port 24 of the bag main body 12. As shown in FIG. 5, the lid 14 is formed by injection molding or the like, and includes a disk-shaped zenith portion 60. The outer diameter of the zenith portion 60 is the same as or substantially the same as the outer diameter of the side wall portion 20 of the heel body 12, and when the lid 14 is attached to the inspection port 24 of the heel body 12, the side wall portion of the heel body 12. The upper end 22 of 20 and the lower surface peripheral part of the zenith part 60 contact | abut. In addition, two concave portions 62 are formed on the top surface of the zenith portion 60. The concave portion 62 is used as a grip portion into which an operator's finger is inserted when the lid 14 is attached or detached.

  Further, a short cylindrical fitting portion 64 is formed on the lower surface of the zenith portion 60. The fitting portion 64 is a portion that is fitted into the inspection port 24, and when the lid 14 is attached to the inspection port 24 of the bag main body 12, the outer surface of the fitting portion 64 is along the inner surface of the side wall portion 20 of the bag main body 12. A groove 66 extending in the circumferential direction is formed on the outer surface of the fitting portion 64, and a seal member 68 is mounted in the groove 66. The outer diameter of the fitting portion 64 is set to be slightly smaller than the inner diameter of the side wall portion 20 of the bag main body 12 so that the fitting portion 64 can be fitted into the inspection port 24 with the seal member 68 attached.

  The seal member 68 is an annular packing such as an O-ring formed of rubber such as styrene butadiene rubber (SBR) and ethylene propylene rubber (EPDM). FIG. 5 shows a seal member 68 having a substantially circular cross section. As the seal member 68, one having an appropriate cross-sectional shape such as a rectangular cross section and an irregular cross section can be used. By this seal member 68, airtightness and watertightness between the fitting portion 64 and the inspection port 24 (that is, the upper end portion of the side wall portion 20 of the bag main body 12) are maintained.

  Further, as shown in FIG. 6, the pressing member 16 is formed by injection molding or the like, presses the lid 14 in cooperation with the heel body 12, and prevents the lid 14 from being inadvertently detached from the heel body 12. Here, cooperation means that two or more members cooperate to perform a function.

  The pressing member 16 includes an upper wall portion 70 formed in a donut plate shape, and a short cylindrical side wall portion 72 formed so as to extend downward from the peripheral surface of the lower surface of the upper wall portion 70. A plurality of ribs 74 are formed on the outer surface of the side wall portion 72 of the pressing member 16 and extend in the vertical direction and are arranged at predetermined intervals in the circumferential direction. The rib 74 increases the rigidity of the pressing member 16. In addition, since the operator can place a finger on the rib 74, the pressing member 16 can be easily rotated in the circumferential direction.

  In addition, on the inner surface of the side wall portion 72 of the pressing member 16, four second claw portions 76 projecting inward are formed at positions corresponding to the four first claw portions 26 of the heel body 12. The second claw portion 76 includes a lateral portion 78 that extends in the circumferential direction along the lower inner surface of the side wall portion 72, and a longitudinal portion 80 that extends upward from one end of the lateral portion 78. 80 to form an L shape.

  When attaching the presser member 16 to the heel body 12, the lid 14 is first attached to the inspection port 24 of the heel body 12, and the presser member 16 is attached from above the lid 14. Specifically, the upper end portions of the lid 14 and the side wall 20 of the heel body 12 are inserted into the side wall 72 of the pressing member 16. Then, by rotating the pressing member 16 in the circumferential direction, the first claw portion 26 of the heel body 12 is inserted between the upper wall portion 70 of the pressing member 16 and the lateral portion 78 of the second claw portion 76. The presser member 16 is fixed to the heel body 12. In other words, bayonet coupling, which is fixed by inserting and rotating, is used for attaching the pressing member 16. In addition, the vertical part 80 of the 2nd nail | claw part 76 is utilized as a stopper.

  When the pressing member 16 is attached to the heel body 12, the upper surface of the lateral portion 78 of the second claw portion 76 of the pressing member 16 comes into contact with the lower surface of the first claw portion 26 of the heel body 12 as shown in FIG. The upper surface of the zenith portion 60 contacts the lower surface of the upper wall portion 70 of the pressing member 16. Since the upward movement of the pressing member 16 is restricted by the contact between the second claw portion 76 and the first claw portion 26, the lid 14 pressed by the pressing member 16 is firmly fixed. That is, the collar body 12 and the pressing member 16 cooperate to hold the lid 14 firmly.

  Since the fitting portion 64 of the lid 14 is only fitted into the inspection port 24, this alone may cause the lid 14 to come off from the inspection port 24 when the pressure in the bag main body 12 rises. There is. However, as described above, pressing the lid 14 with the pressing member 16 prevents the lid 14 from being inadvertently detached from the bag main body 12. In other words, since the lid 14 is firmly held by the holding member 16, the lid 14 such as bayonet coupling is fixed by taking into consideration that the lid 14 is inadvertently detached from the inspection port 24. It is not necessary to adopt the method of doing this, and the lid 14 need only be mounted in a state of being fitted into the inspection port 24.

  Further, when removing the lid 14 from the main body 12 in order to perform inspection work, cleaning, etc. of the main body 10, first, the presser member 16 is reversely rotated and removed, and then the concave portion 62 formed in the zenith section 60 is used. Then, the lid 14 is removed.

  As described above, since the seal member 68 is attached to the fitting portion 64 of the lid 14 so as to extend in the circumferential direction, when the seal member 68 is in a fixed state, the lid 14 itself is rotated in the circumferential direction. In order to do so, a great deal of power is required. However, in this embodiment, only the fitting portion 64 of the lid 14 is fitted into the inspection port 24, and when removing the lid 14, there is no need to rotate the lid 14 in the circumferential direction.

  Therefore, according to this embodiment, even if the seal member 68 is in a fixed state, the lid 14 can be easily removed with a small force without using a turning jig or the like for removing the lid 14. For this reason, it becomes easy for an operator to enter under the floor 100 and remove the lid 14 there to perform inspection work and cleaning, and the maintenance management of the bag 10 is improved. Further, since there is no restriction that the cage 10 has to be installed under the inspection port provided on the floor 100, the cage 10 can be arranged at an appropriate place such as near the wall of the foundation 104, and the space below the floor 100 can be set in other places. It can be used effectively for various purposes.

  The shape of the pressing member 16 is not limited to that shown in FIG. 6, and an appropriate shape can be adopted. For example, the upper wall portion 70 may be formed in a disk shape. Further, for example, instead of forming the side wall portion 72 of the pressing member 16 in a short cylindrical shape, only at a position where the second claw portion 76 is formed, that is, only at a position corresponding to the first claw portion 26 of the heel body 12, The arc-shaped side wall 72 may be formed in a dispersed manner.

  Moreover, although the bayonet coupling | bonding was utilized for attachment of the pressing member 16, it is not limited to this. For example, a screw thread is formed on the outer surface upper part of the heel body 12 and a screw groove that is screwed with the screw thread is formed on the inner surface of the side wall portion 72 of the presser member 16. May be attached to the bag main body 12.

  Furthermore, the pressing member 16 does not necessarily need to press the lid 14 by rotating in the circumferential direction and being attached to the bag main body 12, and can hold the lid 14 by an appropriate method. For example, as shown in FIG. 8, the hook body 12 is formed with a first locking portion 90 projecting outward from the upper end 22, and the lid 14 corresponds to the first locking portion 90. A second locking portion 92 that protrudes outward from the side surface of the zenith portion 60 is formed at the position. When the lid 14 is attached to the inspection port 24, the positions of the first locking portion 90 and the second locking portion 92 are aligned, and the presser member 16 formed in a frame shape is fitted therein. The lid 14 can be pressed. In this case, the pressing member 16 and the first locking portion 90 of the heel body 12 cooperate to press the lid 14 so that it does not come off from the inspection port 24 of the heel body 12.

  In addition, for example, by holding the presser member 16 rotatably attached to the side surface of the top plate portion 60 of the lid 14 using a hinge mechanism to a locking portion formed on the outer surface of the heel body 12. The lid 14 can also be pressed so as not to be detached from the bag main body 12.

  However, when the hinge mechanism is used, there is a concern that the structure becomes complicated and the manufacturing cost of the bag 10 increases. Further, when the presser member 16 shown in FIG. 8 is used, it is necessary to accurately align the positions of the first locking portion 90 and the second locking portion 92, and it is attached in a narrow place such as under the floor 100. There is a concern that will become difficult. Therefore, it is desirable to use the presser member 16 that uses bayonet coupling or screw coupling that is easy to mount.

  Further, the shape of the lid 14 is not limited to that shown in FIG. 5, and an appropriate shape can be adopted.

  For example, in the lid 14 shown in FIG. 5, the concave portion 62 for inserting a finger is formed on the upper surface of the zenith portion 60, but instead of the concave portion 62, a handle is formed on the upper surface of the zenith portion 60. And the lid 14 can be removed from the inspection port 24.

  Further, instead of the concave portion 62 or together with the concave portion 62, for example, a notched portion formed by notching a part thereof may be provided at the lower end of the side surface of the zenith portion 60. In this case, a jig such as a screwdriver may be inserted between the notch, that is, the lid 14 and the bag main body 12, and the lid 14 may be removed from the inspection port 24 using the principle of leverage. As a result, the lid 14 can be removed more easily. In addition, since the jig | tool in this case only inserts from the side of the coffin main body 12, and lifts the lid | cover 14, it can be used also under the floor 100 with a restriction | limiting in a height direction. Further, such a notch may be formed at the upper end 22 of the side wall 20 of the bag main body 12.

  In the above-described embodiment, the upper end 22 of the side wall portion 20 of the heel body 12 and the lower peripheral edge of the zenith portion 62 of the lid 14 are brought into contact, that is, the zenith portion 62 is above the upper end 22 of the heel body 12. Although it came to a position, it is not limited to this. For example, the zenith portion 62 itself may be fitted into the inspection port 24, and the zenith portion 62 may also serve as the fitting portion 64. In this case, it is preferable that the upper end 22 of the side wall portion 20 and the upper surface of the zenith portion 60 are flush with each other when the lid 14 is attached to the heel body 12.

  Further, the lid 14 is not necessarily formed with the fitting portion 64, and the lid 14 formed only by the zenith portion 60 may be used. For example, a groove 66 is formed on the peripheral edge of the lower surface of the zenith portion 60, and a seal member 68 is attached to the groove 66. And it is good to attach the lid | cover 14 to the inspection port 24 so that the sealing member 68 may be contact | abutted to the upper end 22 of the side wall part 20 of the bag main body 12. FIG. In this case, the pressing member 16 may be formed not only to press the lid 14 downward, but also to prevent the lateral lid 14 from being displaced. For example, a protrusion that protrudes inward is provided on the inner surface of the side wall 72 of the pressing member 16, and the end of the protrusion is brought into contact with the side surface of the zenith portion 60 of the lid 14. It is good to prevent deviation. In this way, even if the lid 14 is simply put on the inspection port 24, the pressing member 16 can hold the lid 14, so that the lid 14 can be prevented from being inadvertently detached from the bag body 12, and The lid 14 can be easily removed when the bag 10 is inspected.

  Instead of fitting the fitting portion 64 of the lid 14 into the inspection port 24, the inspection port 24 (that is, the upper end portion of the side wall portion 20 of the bag main body 12) may be fitted into the fitting portion 64. In this case, for example, the short cylindrical fitting portion 64 having an inner diameter corresponding to the outer diameter of the side wall portion 20 of the heel body 12 so as to protrude downward from the lower peripheral edge portion of the top portion 60 of the lid 14. It is preferable to form the groove 66 on the inner surface of the fitting portion 64 and attach the seal member 68. Further, the first claw portion 26 is formed on the outer surface of the side wall portion 20 of the heel body 12 at a position lower than the lower end of the fitting portion 64 of the lid 14, and the first claw portion 26 and the receiving portion 78 of the pressing member 16 are provided. The presser member 16 may be attached to the heel body 12 using the lid 14 and the lid 14 may be pressed.

  Further, as described above, the partition body 40 may be detachably provided inside the bag main body 12. Referring to FIG. 4, the partition body 40 is formed by injection molding or the like, and includes a contact plate 42 and a partition plate 44.

  The contact plate 42 is a plate-like body that is formed so as to face the stepped portion 28 of the bag main body 12, and upper portions on both sides thereof are along both side ends of the stepped portion 28. In addition, a first contact portion 46 that protrudes outward is formed at the upper end of the contact plate 42. The first abutting portion 46 is formed in a shape along the stepped first support portion 30 of the stepped portion 28, and when the partition body 40 is attached to the heel body 12, the first abutting portion 46 and the first support are formed. The part 30 contacts (see FIG. 2).

  The partition plate 44 divides between the inflow portions 34 and is formed at each position facing the inflow portions 34. Specifically, the partition plate 44 has a main surface 44 a that faces the inflow portion 34, and is a plate-like body that curves toward the inflow portion 34 as it goes upward and both sides from the center of the lower end of the main surface 44 a. Formed. That is, the partition plate 44 covers the opening portion 48 (see FIG. 3) of the inflow portion 34 on the center side of the heel body 12 in a bowl shape, and the upper side surface 50 of the partition plate 44 extends over the upper half circumference of the opening portion 48. Along the inner surface of the side wall 20 of the heel body 12. Moreover, the side surface lower part 52 of the partition plate 44 curves so that a parabola may be drawn toward an inner side as it goes to a lower end. That is, the side surface lower part 52 of the partition plate 44 and the inner surface of the side wall part 20 of the bag main body 12 are separated, and a space is formed between them. This space communicates the drainage passages partitioned by the partition plate 44 in the circumferential direction of the main body 12.

  Further, the partition body 40 includes a wall portion 54 whose outer surface is flush with the side surface upper portion 50 of the partition plate 44. The wall portion 54 is formed in a substantially cylindrical shape integrally with the contact plate 42, and the outer surface of the wall portion 54 is along the inner surface of the side wall portion 20. The upper end of the wall portion 54 is formed with a second contact portion 56 that protrudes outward along with the first contact portion 46 over the entire circumference. When the partition body 40 is attached to the heel body 12, the second contact portion 56 and the second support portion 32 are in contact with each other, and the upper surfaces of the first contact portion 46 and the second contact portion 56 are Form the same surface as the top surface.

  When the lid 14 is attached to the inspection port 24 of the bag main body 12, the lower end of the fitting portion 64 of the lid 14 comes into contact with the upper surfaces of the first contact portion 46, the second contact portion 56, and the step portion 28. . Accordingly, the partition body 40 is sandwiched between the bag main body 12 and the lid 14 (see FIG. 7) and is firmly fixed. Therefore, even if the wastewater collides with the partition body 40, the partition body 40 is loose. Not stick.

  When such a partition body 40 is used, the wastewater flowing from the inflow portion 34 can be guided and the flow direction of the wastewater can be smoothly changed downward, so that the backflow of the wastewater to the other inflow portion 34 is prevented. it can. In addition, when a large amount of drainage flows into the bag main body 12 at a time, the drainage flows downward and flows out from the outflow portion 38, and between the side surface lower portion 52 of the partition plate 44 and the side wall portion 20. It also flows in the circumferential direction (lateral direction) through the space. That is, since the drainage can be discharged not only using the drainage passage partitioned by the partition plate 44 corresponding to each inflow portion 34 but also using the drainage passage corresponding to the other inflow portion 34, the main body 12 The occurrence of a full water condition can be prevented. Therefore, it is not necessary to increase the tube diameter of the rod main body 12 in order to secure the drainage passage in the portion partitioned by the partition plate 44 and prevent the water from filling up, and the rod 10 can be downsized.

  Moreover, as shown in FIG. 9, the lid | cover 14 provided with the one-way ventilation valve 110 can also be used. In the following, the embodiment shown in FIG. 9 will be described, but the description overlapping the embodiment shown in FIG. 1 will be omitted or simplified.

  As shown in FIG. 10, the lid 14 includes a top cylindrical inner tube portion 112 and a flange portion 114 formed on the outer surface of the inner tube portion 112. The peripheral edge of the lower surface of the flange 114 abuts on the upper end 22 of the side wall 20 of the flange body 12. Further, the inner cylinder portion 112 is formed with a vent hole 116 for communicating the inside of the heel body 12 and the outside air at a position higher than the heel portion 114. Furthermore, a cylindrical fitting portion 118 is formed on the lower surface of the flange portion 114. The outer surface of the fitting portion 118 is along the inner surface of the side wall portion 20 of the heel body 12, and the sealing member 120 attached to the outer surface of the fitting portion 118 is provided between the side wall portion 20 of the heel body 12 and the fitting portion 118. Airtightness and watertightness are maintained.

  Further, the one-way vent valve 110 is attached to the inside of the inner cylinder portion 112 by using bayonet coupling or screw coupling. On the other hand, the vent valve 110 is normally closed, and reliably prevents leakage of drainage to the outside and leakage of bad odor in the bag 10. On the other hand, when a negative pressure is generated in the bag main body 12, the vent hole 116 and the bag main body 12 are communicated to take outside air into the bag main body 12, and the bar main body 12 is maintained at atmospheric pressure.

  As shown in FIG. 11, the pressing member 16 includes an upper wall portion 70 formed in a donut plate shape, and the diameter of the circular hole 122 formed in the center thereof is the outer diameter of the inner cylinder portion 112 of the lid 14. Is set to approximately the same size. When the pressing member 16 is attached to the heel body 12, the inner cylindrical portion 112 of the lid 14 is inserted into the hole 122, and the edge of the hole 122 abuts the outer surface of the inner cylindrical portion 112. Further, a short cylindrical side wall portion 72 extending downward is formed on the peripheral surface of the lower surface of the upper wall portion 70. On the inner surface of the side wall portion 72, four second claw portions 76 projecting inward are formed at positions corresponding to the four first claw portions 26 of the heel body 12. The 2nd nail | claw part 76 contains the horizontal part 78 extended in the circumferential direction along the inner surface lower end of the side wall part 72, and the vertical part 80 extended toward the upper direction from one end of the horizontal part 78, and is formed in an L shape. .

  Further, a bulky portion 124 is formed on the lower surface of the upper wall portion 70. The bulky portion 124 is formed integrally with the upper end of the vertical portion 80 of the second claw portion 76 so as to extend inward. Referring to FIG. 9, the lower surface of the bulky portion 124 abuts on the upper surface of the collar portion 114 of the lid 14, thereby providing a space between the lower surface of the upper wall portion 70 of the pressing member 16 and the upper surface of the collar portion 114 of the lid 14. 126 is formed. The height of this space, that is, the height of the bulk upper portion 124 is set to be substantially the same as the height of the vent hole 116 of the lid 14 or larger than the height of the vent hole 116, and the upper wall portion 70 of the pressing member 16 116 is covered. Moreover, since the 1st nail | claw part 26 and the 2nd nail | claw part 76 are formed in the side wall part 20 outer surface of the heel main body 12, and the side wall part 72 inner surface of the pressing member 16, the side wall part 20 outer surface and the pressing member of the heel main body 12 are formed. A space 128 is also formed between the sixteen side walls 72, and the vent holes 116 communicate with the outside through the space 126 and the space 128.

  By forming the presser member 16 in this way, the upper wall portion 70 of the presser member 16 covers the flange portion 114 of the lid 14, so that foreign matter such as dust is less likely to accumulate on the upper surface of the flange portion 114 of the lid 14. When the ventilation valve 110 is opened and outside air is taken into the bag main body 12, dust and the like can be prevented from being sucked from the ventilation holes 116. Accordingly, it is possible to prevent dust and the like from adhering to the one-side vent valve 110 and reducing its sealing performance.

  However, the bulky portion 124 of the pressing member 16 is not necessarily formed, and the vent hole 116 may directly communicate with the outside without passing through the spaces 126 and 128. For example, the diameter of the hole 122 of the upper wall part 70 is set larger than the outer diameter of the inner cylinder part 112, and a gap is formed between the edge of the hole 122 of the upper wall part 70 and the outer surface of the inner cylinder part 112. Alternatively, the vent hole 116 may be formed at a position higher than the upper surface of the upper wall portion 70.

  In each of the embodiments described above, the heel body 12 as shown in FIG. 3 is used. However, the shape and configuration of the heel body 12 are not limited to this, and the heel body 12 having an appropriate shape and configuration is used. be able to. For example, the bag main body 12 does not necessarily have a plurality of inflow portions 34 and may have only one inflow portion 34. For example, the outflow part 38 can be provided in the side wall part 20, and waste_water | drain can also be discharged | emitted from a side.

  Further, in each of the embodiments described above, the seal member 68 is attached to the lid 14, but the seal member 68 can also be attached to the bag main body 12.
