[0005] Patent Document 1: Japanese Patent Application Publication No. 2017-136179 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] However, the toilet device disclosed in Patent Document 1 uses a tubular object as a resin film for storing waste, and continuously provides a tubular resin film by repeatedly packaging and cutting the film. In order to continuously provide a film for storing waste, the sealing device needs to repeatedly convey the film, and in order to convey the film, the sealing device needs to have a roller and a motor for driving the roller, as well as a control unit for controlling the motor. However, a sealing device with such a drive system and control system inevitably has a complex structure and is troublesome to repair and maintain. In addition, there is a problem that the device is impeded from being miniaturized and lightweight due to the complex structure, and further, there is a problem that the manufacturing cost increases due to the increase in components.

[0008] The present invention has been made in view of the above problems, and an object of the present invention is to provide a sealing device having a simple structure and capable of sealing a bag-shaped film body for storing wastes, etc., and to provide a bag-shaped film body having a structure suitable for sealing by the sealing device.

[0009] Technical solutions to the problem

[0010] In order to achieve the above-mentioned objectives, first, the present invention provides a sealing device to seal the opening of a bag-like film body, and the sealing device is configured to include: a frame component, which includes: an opening portion, on which the bag-like film body is inserted; a locking portion, on which a first portion of the bag-like film body on the end edge portion of the opening is locked; and a heater portion, which is arranged next to the locking portion; a moving component, which includes: a mounting portion, on which a second portion located at a position opposite to the first portion of the bag-like film body on the end edge portion of the opening is mounted; and a heater support portion, which is arranged next to the mounting portion; a handle component, which is freely slidably inserted into the frame component and connected to the moving component, wherein the moving component is configured to be able to move toward the locking portion in the opening, and when the moving component is moved to the side of the locking portion through the handle component, the bag-like film body clamped by the heater portion and the heater support portion is heated and sealed (first aspect).

[0011] According to the invention (first aspect), when the bag-like film body is inserted into the opening of the frame part, a part of the end edge of the opening of the bag-like film body can be stopped at the stop part of the frame part, and at the same time, another part of the bag-like film body located at a position opposite thereto can be installed to the mounting part of the movable part, and the installed movable part can be moved toward the stop part by the handle part. By moving the movable part toward the stop part, the end edge of the opening of the bag-like film body is folded and gathered, and the folded bag-like film body is clamped between the heater part and the heater support part, wherein the heater part is arranged next to the stop part on the frame part, and the heater support part is arranged next to the mounting part on the movable part, so that the bag-like film body can be heated in this state for sealing. Such a sealing device is not only simple in structure and easy to repair and maintain, but also can tightly seal the bag-like film body that stores waste and the like.

[0012] In the above invention (first aspect), a pair of left and right pushing parts can also be provided. As the movable part moves toward the locking part, the pushing part will push the third part and the fourth part toward the center direction of the opening, wherein the third part and the fourth part are located between the first part and the second part of the bag-like membrane at the end edge of the opening (second aspect).

[0013] According to the invention (the second aspect), when the movable part is moved toward the locking part, the pushing part pushes the side portions of the end edges of the opening of the bag-like membrane body toward the center of the opening from the left and right sides. Therefore, the opening attachment of the bag-like membrane body is folded tightly and gathered and will not overflow to the outside, thereby clamping the folded bag-like membrane body between the heater part and the heater support part.

[0014] In the above invention (first aspect), the handle component comprises: a pair of left and right rod-like portions arranged in parallel, and a holding portion spanning the ends of the left and right pair of rod-like portions, and the left and right pair of rod-like portions can be freely slidably inserted into a pair of insertion portions, wherein the insertion portions are arranged on the left and right of the opening portion of the frame component (third aspect).

[0015] According to the invention (claim 3), the handle member does not interfere with the opening of the frame member, and the movable member can be connected to the rod-shaped portion from both sides. Therefore, the movable member can be moved smoothly by operating the handle member.

[0016] In the above invention (third aspect), the sealing device may have the following configuration: The pair of left and right rod-shaped parts respectively include: a rod part connected to the holding part, and a base end part connected to the moving part, wherein the rod part is axially fixed to the base end part and can be tilted relative to the base end part, and when the rod part is pulled out of the insertion part, when the rod part is tilted to a predetermined position relative to the base end part, the heater part enters a heating state (fourth aspect).

[0017] According to the invention (fourth aspect), after the movable part is moved by the handle part and the folded bag-like membrane is clamped between the heater part and the heater support part, the rod part is tilted relative to the base end part and the heater part starts to heat, thereby ensuring safety during the sealing operation.

[0018] In the above invention (claim 1), the exhaust member may be suspended from the moving member, wherein the exhaust member has a contact surface that contacts the bag-like film body (claim 5).

[0019] According to the invention (fifth aspect), since the abutment surface will be pressed against the bag-like membrane body while the moving part moves, in this state, the exhaust part moves, so that the air in the bag-like membrane body is squeezed out from the opening, thereby preventing the bag-like membrane body from bulging due to air when the opening is sealed.

[0020] In the above invention (claim 5), the contact surface may have a convex shape protruding toward the locking portion (claim 6).

[0021] According to this invention (the sixth aspect), the air in the bag-like film body can be squeezed out from the opening more effectively.

[0022] In the above invention (claim 5), the exhaust member may be suspended from the moving member and may be swung relative to the moving member so that movement of the moving member toward the locking portion is not restricted (claim 7).

[0023] According to the invention (the seventh aspect), even if the exhaust component hits the waste contained in the bag-like membrane body during the movement of the moving component toward the stopper, the exhaust component can swing relative to the moving component, so the further movement of the moving component toward the stopper will not be restricted. In other words, it is possible to prevent the moving component from being unable to move during the movement due to interference between the exhaust component and the waste contained in the bag-like membrane body.

[0024] In the above invention (aspect one), a heater support guide plate may be provided at the lower side of both ends of the heater support portion, which guides the bag-like film body from the two ends of the heater support portion toward the center portion, and / or a heater guide plate may be provided at the lower side of both ends of the heater portion, which guides the bag-like film body from the two ends of the heater portion toward the center portion (aspect eight).

[0025] According to the invention (aspect eight), the end edge of the opening of the bag-like membrane body which is folded up due to the movement of the moving part can be prevented from extending further outward beyond the welding width of the heater support part and the heater part due to the presence of the heater support part guide plate and / or the heater part guide plate.

[0026] Second, the present invention provides a bag-shaped membrane body, wherein a plate member having a polygonal ring shape when viewed from above is circumferentially arranged at the end edge of an opening, wherein the plate member is formed by connecting a plurality of long strip plate portions respectively through a plurality of free bending portions (ninth aspect).

[0027] According to the invention (ninth aspect), the opening edge of the bag-like film body can be easily and smoothly folded by installing a plate member at the opening edge of the bag-like film body and applying a force and a pushing force to the plate member from the outside to move the plate member.

[0028] In the above invention (ninth aspect), the plate component includes 6 plate portions, namely the first plate portion, the second plate portion, the third plate portion, the fourth plate portion, the fifth plate portion, and the sixth plate portion, and the 6 plate portions can be connected through the 6 free bending portions (tenth aspect).

[0029] In the above invention (the tenth aspect), starting from the free bending portion between the first plate portion and the second plate portion, the six free bending portions are, in sequence, the first free bending portion, the second free bending portion, the third free bending portion, the fourth free bending portion, the fifth free bending portion, and the sixth free bending portion, wherein the first free bending portion, the third free bending portion, the fourth free bending portion, and the sixth free bending portion are formed so that the outer side of the opening is mountain-shaped and easy to bend, and the second free bending portion and the fifth free bending portion are formed so that the inner side of the opening is mountain-shaped and easy to bend (the eleventh aspect).

[0030] According to the invention (the eleventh aspect), between the first plate portion and the fourth plate portion, starting from the first plate portion side, the plate portion can be folded in a manner in which the second plate portion, the third plate portion, the sixth plate portion, and the fifth plate portion are overlapped in sequence, thereby applying a force and a pushing force to the plate portion from the outside to cause it to move, so that the end edge of the opening of the bag-like membrane body can be easily and smoothly folded.

[0031] In the above invention (the eleventh aspect), the second plate portion and the fifth plate portion may include an auxiliary free bending portion near the center of their respective long side directions, and the auxiliary free bending portion is formed so that the outer side of the opening is mountain-shaped and easy to bend (the twelfth aspect).

[0032] According to the invention (the twelfth aspect), during the folding process of the plate part, the second plate portion and the fifth plate portion are bent near the center in a mountain-shaped manner with the outer sides of the openings, so that the plate part can be folded more smoothly between the first plate portion and the fourth plate portion, starting from the first plate portion side, in a manner in which the second plate portion, the third plate portion, the sixth plate portion, and the fifth plate portion are overlapped in sequence.

[0033] In the above invention (aspects 10 to 12), if the bag-shaped membrane body is installed in the sealing device in the first aspect, preferably, the first plate portion is installed on the movable part as the first part, and the fourth plate portion is installed on the locking portion as the second part (aspect 13).

[0034] In the above invention (claim 9), preferably, the plate member is made of paper, and the freely bendable portion is formed by folding (claim 14).

In addition, the shapes and sizes shown in the drawings are only shown to facilitate understanding of the contents of the present invention, and do not accurately reflect the actual shapes or sizes.

[0102] The definitions of up, down, front, back, left, and right directions in the present invention are based on the state when the toilet device 1 and the sealing device 10 are used, and are specifically defined as follows. First, in the toilet device 1, the side provided with the toilet seat 40 is "up", and the side provided with the base 30 is "down". In addition, in the sealing device 10 constituting the toilet device 1, the side provided with the gripping portion 130 of the handle member 13 described later is "front", and the opposite side is "rear". Furthermore, in the state of observing the sealing device 10 from the front (the state facing the gripping portion 130), the right side direction is "right", and the left side direction is "left". Figure 1 , arrows indicating up, down, front, back, left, and right are shown according to the above-mentioned direction definition.

[0103] <Toilet unit>

[0104] like Figure 1 As shown, the sealing device 10 of this embodiment, together with the base 30 and the toilet seat 40, forms a component of the toilet device 1. In the toilet device 1, the bag-shaped membrane 20 installed on the sealing device 10 contains human excrement, and the sealing device 10 is used to heat-seal the opening of the bag-shaped membrane 20. The toilet device 1 is configured so that the sealing device 10, the base 30 and the toilet seat 40 can be easily disassembled and assembled, and the toilet device can be placed at the bedside of a room in a hospital, a nursing place, an accommodation facility, etc., or can be used as a simple toilet in the event of a disaster or an event.

[0105] The base 30 has a rectangular parallelepiped shape with an open top and bottom, and is formed by connecting six plate-like members and being foldable. A sealing device 10 is placed on the top of the base 30, and the sealing device 10 is detachably fixed to the upper edge of the base 30. In addition, a toilet seat 40 on which a user of the toilet device 1 can sit is installed on the top of the sealing device 10 placed on the base 30.

[0106] <Bag-like membrane>

[0107] Figure 2 This is an explanatory diagram showing the structure of the bag-shaped film body 20 sealed by the sealing device 10. In the bag-shaped film body 20 installed and used in the sealing device 10 of this embodiment, a plate member 22 having a polygonal ring shape when viewed from above is circumferentially provided on the edge portion 211 of the opening 210 of the resin bag body 21. The plate member 22 is formed by connecting a plurality of long strip-shaped plate portions through a plurality of free bending portions. Specifically, Figure 2 In the figure, the plate member 22 includes 6 plate parts, which are the first plate part A1, the second plate part A2, the third plate part A3, the fourth plate part A4, the fifth plate part A5, and the sixth plate part A6 in clockwise order, and these 6 plate parts are connected by 6 free bending parts (B1, B2, B3, B4, B5, B6). Starting from the free bending part between the first plate part A1 and the second plate part A2, the 6 free bending parts are the first free bending part B1, the second free bending part B2, the third free bending part B3, the fourth free bending part B4, the fifth free bending part B5, and the sixth free bending part B6.

[0108] The material constituting the bag body 21 is not particularly limited as long as it can be heat-sealed by the heater unit 114 of the sealing device 10 described later. For example, it can be a thermoplastic resin, especially a thermoplastic resin with a low melting point and high thermal processability such as polyethylene and polypropylene. The plate member 22 can be attached to the bag body 21 using various well-known methods, such as adhesion with an adhesive, or attachment using a fixing tool such as a stapler, or the end edge 211 of the opening 210 of the bag body 21 can be folded back to form a ring and inserted into the plate member 22.

[0109] The material constituting the plate component 22 can be paper, resin, metal, wood, stone, glass, fiber, etc., and at least it can be made of a material that can maintain its shape even when a certain external force is applied from the outside at room temperature. There is no special limitation. However, considering that the bag-like membrane body 20 will be thrown away after storing waste such as excrement, the plate component 22 is preferably made of paper or resin, and is especially preferably made of paper that can be easily formed into multiple free bending parts through crease processing.

[0110] In the present embodiment, the plate member 22 is made of paper, and is formed into a polygonal ring shape when viewed from above by connecting the two ends of a long strip of thick paper. In addition, the first free bending portion B1, the third free bending portion B3, the fourth free bending portion B4, and the sixth free bending portion B6 of the plate member 22 are formed by folding processing, so that the outer side direction of the opening 210 is mountain-shaped and easy to bend, and the second free bending portion B2 and the fifth free bending portion B5 are also formed by folding processing, so that the inner side direction of the opening 210 is mountain-shaped and easy to bend. Further, near the center of the long side direction of the second plate portion A2, a second plate auxiliary free bending portion C2 is formed by folding processing, so that the outer side direction of the opening 210 is mountain-shaped and easy to bend, and near the center of the long side direction of the fifth plate portion A5, a fifth plate auxiliary free bending portion C5 is formed by folding processing, so that the outer side direction of the opening 210 is mountain-shaped and easy to bend.

[0111] The bag-like film body 20 in this embodiment can easily and smoothly fold the end edge portion 211 of the opening 210 of the bag-like film body 20 by installing a plate part 22 on the end edge portion 211 of the opening 210 of the bag-like film body 20 and applying a force and a pushing force to the plate part 22 from the outside to move it.

[0112] <Sealing device>

[0113] Figure 3 The diagrams are for explaining the overall structure of the sealing device 10, wherein (a) is a perspective view of the sealing device 10 viewed from the upper side (outside), and (b) is a perspective view of the sealing device 10 viewed from the lower side (inside). The sealing device 10 is a sealing device for sealing the opening of a bag-shaped membrane such as a plastic bag, and includes: a frame component 11, a moving component 12, a handle component 13, and a pair of left and right pushing components 14. It should be noted that in order to facilitate the understanding of the structure of the sealing device, Figure 3 (b) shows a state where the handle member 13 is removed from the sealing device 10 .

[0114] The frame member 11 has a generally rectangular shape, and includes: a flat frame bottom 110, wherein an opening 111 into which the bag-shaped membrane 20 is inserted is formed in the center; and a side wall 112, which is uprightly arranged at the edge of the frame bottom 110. The shape and size of the opening 111 correspond to the toilet seat 40 installed on the upper part of the sealing device 10. In the present embodiment, the opening 111 is formed into a polygonal shape that is generally barrel-shaped when viewed from above. The opening 111 is not particularly limited as long as it is formed into a shape and size that can drop excrement from the upper side, and can be, for example, rectangular when viewed from above, or circular, elliptical, etc.

[0115] A stopper is provided at the front end of the opening 111, on which the first plate portion A1 of the bag-like film body 20 (as the first part of the bag-like film body 20 on the end edge portion 212 of the opening 211) is stopped, and the stopper is composed of two clamping parts 113. The two clamping parts 113 are installed on the front side wall portion 112a of the frame part 11 at intervals in a manner that they can respectively clamp the two ends of the first plate portion A1 of the bag-like film body 20. The clamping part 113 is a part with a U-shaped cross section, wherein a stopper groove 1133 is formed between the two plate-like parts 1131 and 1132, and the width of the stopper groove 1133 is substantially equal to the thickness of the first plate portion A1 of the bag-like film body 20. Due to such a structure, the first plate portion A1 of the bag-like film body 20 can be stopped on the clamping part 113 (stopper) by inserting the first plate portion A1 into the stopper groove 1133.

[0116] A heater unit 114 is provided beside the clamping member 113 (stopping portion), specifically, on the front side wall portion 112a of the frame member 11 and below the position where the clamping member 113 is installed. The heater unit 114 in this embodiment includes a heating surface (not shown) in which a linear heating wire (not shown) is embedded, and the heating surface faces the opening 111. When the bag-like film body 20 is clamped between the heating surface and the heater support portion 121 of the moving member 12 described later, the bag-like film body 20 is heated by the heater unit 114, and the bag-like film body 20 is sealed by heat welding of the heated portion.

[0117] like Figure 3 As shown in (b), a pair of insertion parts 115 are provided on the left and right sides of the opening 111 of the frame part 11. The surface of the insertion part 115 facing the opening 111 is an open surface and its cross section is a U-shaped surface, and the rod-shaped part 131 on the handle part 13 described later can be freely slidably inserted therein. Figure 3 (b) shows the state where the handle component 13 is removed) The insertion portion 115 has no particular limitation on its shape as long as the rod-shaped component 131 of the handle component 13 can be freely slidably inserted therein and the inserted rod-shaped component 131 does not fall off the frame component 11. For example, it can be formed into a cylindrical shape, or it can be formed by installing a groove-shaped guide rail component that fits with a part of the rod-shaped component 131 on the frame component.

[0118] The moving member 12 is configured to move in the opening 111 of the frame member 11 toward the locking portion composed of the two clamping members 113, that is, toward the front side wall 112a of the frame member 11. The moving member 12 can move in the opening 111 of the frame member 11 by operating the handle member 13 described later.

[0119] like Figure 4As shown, the upper part of the movable part 12 is provided with a mounting portion consisting of two clamping parts 120, on which the fourth plate portion A4 of the bag-like film body 20 (i.e., the second portion located at a position opposite to the first portion of the bag-like film body 20 on the end edge portion 211 of the opening 210) is mounted. The two clamping parts 120 are installed at intervals on the upper part of the movable part 12 in a manner that they can respectively clamp the two ends of the fourth plate portion A4 of the bag-like film body 20. The clamping parts 120 mount the movable plate portion 1202 on the block-shaped base 1201 through spring hinges, and the movable plate portion 1202 is in a state of being pressed against the base 1201 due to the force of the spring hinges. Due to such a structure, the fourth plate portion A4 of the bag-like film body 20 can be mounted on the clamping parts 120 (mounting portion) by inserting the fourth plate portion A4 between the base 1201 and the movable plate portion 1202. In addition, when the sealed bag-like film body 20 is pulled, the movable plate portion 1202 will move away from the base 1201, and the fourth plate portion A4 will be separated from between the base 1201 and the movable plate portion 1202, so that the bag-like film body 20 can be smoothly removed from the movable part 12.

[0120] A heater support portion 121 is provided beside the clamping member 120 (mounting portion) of the moving member 12, specifically, below the position where the clamping member 120 is mounted and at a position opposite to the heater portion 114 provided on the frame member 11. The heater support portion 121 has a length corresponding to the length of the heater portion 114, and when the moving member 12 moves in the opening portion 210 toward the front side wall portion 112a of the frame member 11 (that is, toward the locking portion composed of the two clamping members 113), the heater support portion 121 provided on the moving member 12 abuts against the heating surface of the heater portion 114 provided on the frame member 11.

[0121] An exhaust component 123 is suspended on the bottom 122 of the moving component 12, and the exhaust component 123 has an abutting surface 1231 that abuts against the bag-shaped membrane body 20 installed on the sealing device 10. The exhaust component 123 in this embodiment includes a rectangular flat plate component 1232 and a semi-cylindrical abutting component 1233 for forming the abutting surface 1231. Among the two surfaces of the flat plate component 1232, the abutting component 1233 is provided on the surface (front) located in the direction of the stopper (clamping component 113) provided on the frame component 11. Due to such a structure, the abutting surface 1231 of the exhaust component 1231 has a convex shape protruding in the direction of the stopper (clamping component 113) provided on the frame component 11. The abutting component 1233 has no particular limitation on its shape as long as it has a convex shape protruding in at least one direction, and can be, for example, a triangular prism shape or a quadrangular prism shape.

[0122] By suspending such an exhaust component 123, the exhaust component 123 moves with the contact surface 1231 pressed against the bag-like film body 20 while the moving component 12 moves, so that the air in the bag-like film body 20 is squeezed out from the opening 210, thereby preventing the bag-like film body 20 from bulging due to air when the opening 210 is sealed. In particular, the contact surface 1231 has a convex shape protruding toward the stopper (clamping component 113), so that the air in the bag-like film body 20 can be squeezed out from the opening 210 more effectively.

[0123] In addition, the exhaust component 123 is swingably suspended on the movable component 12 in a manner that does not restrict the movement of the movable component 12 in the direction of the stopper (clamping component 113) provided on the frame component 11. Specifically, the flat plate component 1232 on the exhaust component 123 is mounted on the bottom 122 of the movable component 12 using a hinge, so that the exhaust component 123 can be swingably suspended on the movable component 12. By suspending the exhaust component 123, the movable component 12 can be swung relative to the movable component 12 even if the exhaust component 123 hits the waste etc. stored in the bag-like film body 20 while the movable component 12 is moving in the direction of the stopper (clamping component 113), so that the exhaust component 123 will not be restricted from further moving in the direction of the stopper (clamping component 113). That is, it is possible to prevent the situation that the movable component 12 cannot move on the way due to the interference of the exhaust component 123 with the waste etc. stored in the bag-like film body 20.

[0124] The handle part 13 can be inserted into the frame part 11 in a freely slidable manner, and is also connected to the moving part 12. Figure 4 As shown, the handle member 13 includes a pair of left and right rod-shaped parts 131 arranged in parallel, and a gripping part 130 arranged between the ends of the pair of left and right rod-shaped parts 131. The pair of left and right rod-shaped parts 131 can be freely slidably inserted into a pair of insertion parts 115, and the insertion parts 115 are arranged on the left and right sides of the opening part 111 of the frame member 11. Since the handle member 13 has such a structure, the handle member 13 does not interfere with the opening part 111 of the frame member 11, and the movable part 12 can be connected to the rod-shaped parts 131 from both sides. Therefore, the movable part 12 can be smoothly moved by operating the handle member 13.

[0125] The pair of left and right rod-shaped parts 131 each include a rod part 1311 connected to the gripping part 130, and a base end part 1312 connected to the moving member 12. The rod part 1311 is axially fixed to the base end part 1312 and can be tilted relative to the base end part 1312. It is configured so that when the rod part 1311 is pulled out of the insertion part 115, when the rod part 1311 is tilted to a predetermined position relative to the base end part 1312, for example, when the rod part is tilted to a position where it stands 90 degrees relative to the base end part 1312, the heater part 114 is in a heating state.

[0126] A pair of left and right pushing members 14 are provided on the frame bottom 110 of the frame member 11. The pair of left and right pushing members 14 are symmetrically arranged on both sides of the opening 111 on the frame bottom 110 in a manner of clamping the opening 111. The pair of left and right pushing members 14 move as the moving member 12 moves toward the stopper (clamping member 113) provided on the frame member 11, and push the plate member 22 toward the center direction of the opening 111, wherein the plate member 22 is circumferentially arranged on the end edge 211 of the opening 210 of the bag-like film body 20, and the bag-like film body 20 is installed on the sealing device 10.

[0127] The structure of the pushing member 14 is as follows: a pushing portion 141 having a teardrop-shaped top view is formed at one end of the rod-shaped shaft portion 140, and a cylindrical shaft support portion 142 is formed at the other end. The shaft support portion 142 is fixed to the support portion 116 through the shaft member 143. The support portion 116 is provided on the frame bottom 110 of the frame member 11, so that the pushing portion 141 can move toward the center direction of the opening portion 111 with the shaft support portion 142 and the shaft member 143 as a rotation axis. The shaft member 143 moves as the rod-shaped member 131 of the handle member 13 slides, and the moving member 12 moves toward the stopper (clamping member 113) provided on the frame member 11 through the sliding of the rod-shaped member 131 of the handle member 13, that is, the left and right pair of pushing members 14 move as the moving member 12 moves toward the stopper (clamping member 113) provided on the frame member 11.

[0128] When the pushing portion 141 moves toward the center direction of the opening portion 111, the pushing portion 141 of the pushing portion 14 on the left side will push the second plate portion A2 and the third plate portion A3 (as the third part) toward the center direction of the opening portion 111, and the pushing portion 141 of the pushing portion 14 on the right side will push the fifth plate portion A5 and the sixth plate portion A6 (as the fourth part) toward the center direction of the opening portion 111, wherein the pushing portion 141 on the pushing portion 14 is located between the first plate portion A1 (as the first part) and the fourth plate portion A4 (as the second part) of the plate portion 22, and the plate portion 22 is circumferentially arranged on the end edge portion 211 of the opening 210 of the bag-like membrane body 20, and the bag-like membrane body 20 is installed on the sealing device 10. By arranging a pair of left and right pushing parts 14 in this way, when the movable part 12 is moved toward the stopping part (clamping part 113), the pushing parts 14 will push the side of the end edge 211 of the opening 210 of the bag-like film body 20 toward the center direction of the opening part 111 from the left and right sides. Therefore, the vicinity of the opening 210 of the bag-like film body 20 will be folded tightly and gathered, and the folded bag-like film body 20 will be clamped between the heater part 114 and the heater support part 121 and will not overflow to the outside.

[0129] like Figure 3 As shown in (b), heater support guide plates 15 are provided at the lower sides of both ends of the heater support 121 of the moving member 12, and the heater support guide plates 15 guide the bag-shaped film 20 from both ends of the heater support 121 toward the center. The heater support guide plates 15 are plate-shaped members that are approximately trapezoidal in plan view, and two are provided symmetrically on each side. The two heater support guide plates 15 are installed on the moving member 12 in such a manner that the distance between them gradually decreases and the oblique sides thereof extend in the direction from both ends of the heater support 121 toward the center and in the direction opposite to the heater portion 114.

[0130] In addition, if Figure 3 As shown in (b), heater guide plates 16 are provided at the lower sides of both ends of the heater part 114, and the heater guide plates 16 guide the bag-shaped film body 20 from both ends of the heater part 114 toward the center. The heater guide plates 16 are plate-shaped members that are approximately trapezoidal in plan view, and two are provided symmetrically on each side. The two heater guide plates 16 are mounted on the frame member 11 in such a manner that the distance between them gradually decreases and the oblique sides thereof extend in the direction from both ends of the heater part 114 toward the center and in the direction opposite to the heater support part 121.

[0131] When waste is stored in the bag-shaped film body 20 mounted on the sealing device 10, the bag-shaped film body 20 is stretched open by the weight of the waste and is suspended on the opening 111 of the sealing device 10. If the moving member 12 is moved in this state, the bag-shaped film body 20 is accurately guided to the center of the heater support part 121 by the two heater support guide plates 15, and is also accurately guided to the center of the heater part 114 by the two heater guide plates 16. If the sealing device 10 includes at least one of the heater support guide plate 15 and the heater guide plate 16, the bag-shaped film body 20 is guided to the center of the heater part 114 while being clamped between the heater part 114 and the heater support part 121. However, if both the heater support guide plate 15 and the heater guide plate 16 are included, the bag-shaped film body 20 is more reliably guided to the center of the heater part 114. This can prevent the edge portion 211 of the opening 210 of the bag-shaped film body 20 folded by the movement of the moving member 12 from protruding further outward beyond the welding width between the heater support portion 121 and the heater portion 114 .

[0132] like Figure 3 As shown in (a), guide walls 117 are vertically provided at the four corners of the opening 111 on the frame member 11. The guide walls 117 are used to prevent the plate member 22 of the bag-shaped film body 20 installed on the sealing device 10 from running out during the folding process.

[0133] In this embodiment, when the moving member 12 is moved to the side of the stopper (clamping member 113) through the handle member 13, the bag-shaped film body 20 clamped by the heater member 114 and the heater support member 121 is heated and sealed. Figure 5 As shown, when the rod 1311 of the handle member 13 is pulled out from the insertion portion 115 of the frame member 11 and tilted to a position where it stands 90 degrees relative to the base end portion 1312, the heater portion 114 enters a heating state. With such a configuration, the movable member 12 can be moved by the handle member 13, and the folded bag-shaped film body 20 can be clamped between the heater portion 114 and the heater support portion 121. After that, the heater portion 114 starts heating after the rod 1311 is tilted relative to the base end portion 1312, so that the safety during the sealing operation can be ensured.

[0134] It should be noted that the mechanism for sealing the bag-like film body 20 is not limited to this structure. For example, a detection device (sensor) can be provided to detect that the movable part 12 moves to a predetermined position (the folded bag-like film body 20 is clamped between the heater part 114 and the heater support part 121). When the detection device sends a detection signal, the heater part 114 starts heating. A switch can also be provided to control the start and stop of heating of the heater part 114.

[0135] According to the sealing device 10 described above, when the bag-like film body 20 is inserted into the opening portion 111 on the frame part 11, a part of the end edge portion 211 of the opening 210 of the bag-like film body 20 can be stopped on the stopping portion (clamping portion 113) of the frame part 11, and at the same time, another part of the bag-like film body 20 located at a position opposite to it is installed on the installation portion (clamping portion 120) of the movable part 12, and the installed movable part 12 is moved toward the stopping portion (clamping portion 113) through the handle part 13. By moving the moving part 12 toward the stopper (clamping part 113), the end edge 211 of the opening 210 of the bag-like film body 20 can be folded and gathered, and the folded bag-like film body 20 is clamped between the heater part 114 and the heater support part 121. The heater part 114 is arranged beside the stopper (clamping part 113) on the frame part 11, and the heater support part 121 is arranged beside the mounting part (clamping part 120) on the moving part 12. In this state, the bag-like film body 20 can be heated to be sealed. This sealing device 10 has a simple structure, is easy to repair and maintain, and can tightly seal the bag-like film body 20 that contains waste, etc.

[0136] <Sealing process of bag-shaped film>

[0137] Hereinafter, a specific example of attaching the bag-like film body 20 to the sealing device 10 and a process of sealing the bag-like film body 20 attached to the sealing device 10 will be described. Figure 6 This is an explanatory diagram schematically describing the process of sealing the bag-like film body 20 by the sealing device 10. For the sake of convenience, only the bag-like film body 20, the moving part 12, the pushing part 14, and the clamping part 13 of the frame part 11 are schematically shown. In addition, the bag-like film body 20 is shown in a state of looking down at the plate part 22, and the first free bending part B1, the second free bending part B2, the third free bending part B3, the fourth free bending part B4, the fifth free bending part B5, the sixth free bending part B6, the second plate auxiliary free bending part C2, and the fifth plate auxiliary free bending part C5 are respectively represented by black dots.

[0138] The user of the toilet device 1 installs the bag-like membrane body 20 on the sealing device 10 of the toilet device 1. The first plate portion A1 of the plate member 22 of the bag-like membrane body 20 is installed on the clamping member 120 (installation portion) of the moving member 12 (as the first part), and the fourth plate portion A4 is installed on the clamping member 113 (stopping portion) of the frame member 11 (as the second part). Figure 6 (a) schematically shows a state where the bag-shaped film body 20 is mounted on the sealing device 10 .

[0139] After the user stores waste and the like into the bag-shaped membrane body 20, the user grasps the gripping portion 130 of the handle member 13 with his / her hand and pulls the handle member 13 forward from the frame member 11. Since the moving member 12 is connected to the handle member 13, when the handle member 13 is pulled out, the moving member 12 moves forward (toward the clamping member 113 provided on the frame member 11). The moving member 12 moves forward, so that the first plate portion A1 installed on the clamping member 120 of the moving member 12 moves toward the fourth plate portion A4 installed on the clamping member 113 of the frame member 11. At this time, the pushing portions 141 of the left and right pushing members 14 move toward the center direction of the opening 111 respectively as the moving member 12 moves.

[0140] As mentioned above, the plate member 22 is circumferentially arranged on the end edge 211 of the opening 210 of the bag-shaped membrane body 20, and the plate member 22 includes 6 plate parts, namely the first plate part A1, the second plate part A2, the third plate part A3, the fourth plate part A4, the fifth plate part A5, and the sixth plate part A6, with 6 free bending parts (the first free bending part B1, the second free bending part B2, the third free bending part B3, the fourth free bending part B4, the fifth free bending part B5, and the sixth free bending part B6) in between. The first free bending part B1, the third free bending part B3, the fourth free bending part B4, and the sixth free bending part B6 are formed by folding processing so that the outer side direction of the opening 210 is mountain-shaped and easy to bend, and the second free bending part B2 and the fifth free bending part B5 are also formed by folding processing so that the inner side direction of the opening 210 is mountain-shaped and easy to bend.

[0141] Since the plate member 22 of the bag-shaped membrane body 20 has the above configuration, when the pushing parts 141 of the left and right pair of pushing members 14 move toward the center direction of the opening 111, as shown in FIG. Figure 6 As shown in (b), the pushing component 14 on the right side will push the connecting portion of the second plate portion A2 and the third plate portion A3 (i.e., the second free bending portion B2) to the left, and at the same time, the pushing component 14 on the left side will push the connecting portion of the fifth plate portion A5 and the sixth plate portion A6 (i.e., the fifth free bending portion B5) to the right, and the second free bending portion B2 and the fifth free bending portion B5 are bent in a mountain-shaped manner toward the inner side of the opening 210.

[0142] Furthermore, when the user continues to pull out the handle part 13, the movable part 12 will further move forward, so that the first plate part A1 moves toward the direction close to the fourth plate part A4, and the second plate part A2, the third plate part A3, the fifth plate part A5, and the sixth plate part A6 are folded between the first plate part A1 and the fourth plate part A4. When the second plate part A2 and the third plate part A3 folded from the right side begin to interfere with the fifth plate part A5 and the sixth plate part A6 folded from the left side, the second plate auxiliary free bending part C2 formed near the center of the second plate part A2 and the fifth plate auxiliary free bending part C5 formed near the center of the fifth plate part A5 are respectively bent in a mountain-shaped manner toward the outside of the opening 210, so that the third plate part A3 and the sixth plate part A6 overlap smoothly, presenting a shape like Figure 6 (c) The state shown.

[0143] exist Figure 6 When the handle member 13 is further pulled out in the state (c), and the moving member 12 is further moved forward, the first plate portion A1 approaches the fourth plate portion A4, so that Figure 6 (d) and Figure 6 As shown in (e), the plate member 22 is folded into a generally inverted Z-shape when viewed from above. Finally, after the rod portion 1311 of the handle member 13 is pulled out from the frame member 11, the plate member 22 is folded between the first plate portion A1 and the fourth plate portion A4 in a manner that the second plate portion A2, the third plate portion A3, the sixth plate portion A6, and the fifth plate portion A5 overlap in sequence starting from the first plate portion A1 side, and the folded bag-like film body 20 is clamped between the heater portion 114 and the heater support portion 121. In this state, when the user stands the handle member 13 upward by 90 degrees (i.e., the rod portion 1311 is pulled out from the insertion portion 115 and tilted to a position where it stands 90 degrees relative to the base end portion 1312), the heater portion 114 enters a heating state, and the opening 210 of the bag-like film body 20 is sealed.

[0144] The sealing device and the bag-like membrane provided by the present invention are described above based on the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments and can be modified in various ways. For example, in the present embodiment, the sealing device 10 is applied to the toilet device 1, and the waste stored in the bag-like membrane 20 is toilet excrement, but the present embodiment is not limited to this, and the sealing device 10 can also be applied to a device for disposing used diapers, and can also be applied to a device for processing kitchen waste, etc. In addition, in the above-mentioned embodiment, the bag-like membrane 20 including the plate member 22 is installed on the sealing device 10 for use, but it is not limited to this, and a bag-like membrane such as a generally commercially available plastic bag can be used as a sealing target of the sealing device 10, and the bag-like membrane 20 including the plate member 22 can also be used as a sealing target of a sealing device having a structure different from that of the sealing device 10.

[0145] In addition, in the above-mentioned embodiment, the plate parts constituting the plate member 22 are the first plate part A1, the second plate part A2, the third plate part A3, the fourth plate part A4, the fifth plate part A5, and the sixth plate part A6 in clockwise order, and the free bending parts constituting the plate member 22 are the first free bending part B1, the second free bending part B2, the third free bending part B3, the fourth free bending part B4, the fifth free bending part B5, and the sixth free bending part B6 in clockwise order, but they may also be the first, the second, etc. in counterclockwise order. In this case, the plate member 22 will also be folded into a roughly inverted Z shape when viewed from above, but similar to the case where it is finally folded into a roughly inverted Z shape, the plate member 22 is folded between the first plate part A1 and the fourth plate part A4 in a manner that the second plate part A2, the third plate part A3, the sixth plate part A6, and the fifth plate part A5 overlap in sequence starting from the first plate part A1 side.
