Description

  The present invention relates to an electric kettle, and more specifically, includes a container body in which an inner container made of metal that is heated by a heater is housed in an outer case, and a lid body that closes the inner container at the upper end of the container body. The lid is provided with a pouring path for pouring the content liquid toward the upper front of the container, an open / close mechanism for opening and closing the pouring path, and a steam passage with a water stop function at the time of falling to allow the steam to escape to the outside It relates to a handy type electric kettle.

Kettles have been used for a long time as so-called “kettles” that simply boil hot water on a stove. It has become widespread (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-157

  However, the conventional electric kettle known from Patent Document 1 or the like gives priority to simplicity while being heated by a heater, and the kettle container remains exposed to the outside, the outflow of the contents liquid at the time of falling, the vapor There was no safety against the release. Regarding the safety of the user and the safety of the electrical product itself, the risk factor increases as it is used conveniently.

  Therefore, the present applicant has previously proposed an electric kettle with improved safety, although it does not perform a heat retaining function or complicated control unlike an electric pot (Japanese Patent Application No. 2007-52328). As shown in FIG. 15 (b), this includes a container c containing a metal inner container b that is heated by a heater a in an outer case i, and an inner container b at the upper end of the container c. A lid d for closing, a pouring path e for pouring the content liquid toward the upper front end of the container body c, an opening / closing mechanism f for opening and closing the pouring path e, and steam to the outside And a steam passage g with a water stop function at the time of falling is provided, and a handle h is provided on the container c to provide a handy type electric kettle that can be easily handled.

  In this case, the inner container b, which is a kettle container, is covered with the outer case i, so that the user does not touch it directly to feel hot or get burned, and the heating efficiency is somewhat increased. Further, the content liquid can be poured out only when the inner container b is closed by the lid body d and the pouring path e provided in the lid body d is opened by the opening / closing mechanism f, and the container body c falls down when not pouring including hot water. Even so, it is possible to prevent the content liquid from flowing out through the discharge channel e. Further, the steam passes through a predetermined steam passage g provided in the lid body d, and a predetermined safety position, specifically, a position where the operation part f1 of the opening / closing mechanism f and the attachment / detachment operation part j of the lid body d are provided. For example, because it is released to the lower part of the vessel c, the risk of unlimited discharge from the spout m is suppressed, and the water stop function at the time of the fall, that is, the fall provided in the steam passage g The water stop valve k moves to a position that closes the steam passage g in response to the fall of the vessel c, thereby preventing the liquid content from flowing out through the vapor passage g even if the vessel c falls. can do.

  On the other hand, the steam passage g is bulged around the outer side of the inner container b in order to make contact with the steam sensor l for detecting boiling by detouring through the inside of the container body c through the lid body d and releasing it to the outside. Even if the outer case i is locally expanded to the outside, there is not enough space as a result of being restricted in size to protect the ease of handling, and the aperture shape that narrows from the middle of the inner container b to the mouth As necessary space is secured.

  However, in response to the fact that the steam passage is always open, the use of a water stop valve k for falling with operation to stop water when the body falls will increase costs and support low-cost models It is difficult to make the steam passages dark and wide, making it easy to release steam, which is disadvantageous for water stoppage in the event of a fall, and also because it does not have a heat retaining function, the liquid content can be easily cooled. In order to cope with this, providing a narrow portion in the steam passage limits the discharge of steam through the steam passage too much, and when the content liquid is poured out immediately after boiling, it is particularly smooth when the pouring passage is opened. It is conceivable that the residual steam is likely to be inadvertently blown out through the pouring path designed to be wide for pouring, and the flow of the liquid to be dispensed thereafter may be disturbed or disturbed. In addition, in models with a water stop valve k at the time of tipping, when the content liquid is poured out by tilting the body, the water stop valve k at the time of tipping closes and prevents intake through the steam passage. There is also a problem that cannot be performed smoothly.

  An object of the present invention is to solve such a problem, an electric kettle that exhibits the function of preventing the content liquid from flowing out when the body falls without an operating member, and can smoothly dispense the content liquid without blowing out steam. Is to provide.

  In order to solve the above-mentioned problems, the electric kettle of the present invention closes the inner container through a sealing member at the upper end of the container containing the metal inner container that is heated by the heater in the outer case. In a handy type electric kettle equipped with a lid, the pouring path for pouring the content liquid from the outlet opening in the inner container to the spout toward the upper front of the container, An open / close mechanism that opens and closes the exit path and a steam passage that allows steam to escape to the outside from the steam discharge port are provided. The steam passage is a liquid reservoir that accumulates the liquid that flows in when the body falls and prevents or delays reaching the steam discharge port. The lid is provided with a communication path that branches from the liquid reservoir to the vapor path and communicates with the communication port in the inner container, and the communication path is opened at the same time or earlier by the opening / closing mechanism. Electricity characterized by Torr.

  In such a configuration, the lid that closes the inner container through the seal member allows the inside of the inner container to be connected to the outside of the container for the function of the pouring path and the steam passage, thereby discharging the content liquid and discharging the steam to the outside. However, since the pouring path is securely closed by the open / close mechanism except when pouring the content liquid, the liquid will flow out of the body through the pouring path even if the container falls over during non-pouring, including when boiling. Never do. In addition, the steam passage is always open and the steam generated from the time of boiling water is discharged from the steam outlet of the lid to the outside, preventing the pressure inside the container from falling, and the container falls down. Even if the content liquid flows into the steam passage, the content liquid can be stored in the liquid storage portion and blocked or delayed from reaching the steam discharge port. Furthermore, the communication path that branches from the liquid reservoir and leads to the inner container is opened at the same time or earlier than the outflow path through which the content liquid is poured out by the opening / closing mechanism, and is parallel to the steam path and passes through the inner container. Since it communicates with the liquid reservoir, the remaining steam is prevented from blowing out to the spout side by the amount of the passage area that extends between the inside and outside of the lid, flows into the liquid reservoir of the steam passage, and is discharged from the steam outlet as required. Easy to make. In particular, when the communication path is opened prior to the pouring path, it is possible to further promote the release of residual steam from the steam discharge port before the pouring path is opened. In addition, the communication passage branches off from the liquid reservoir portion of the steam passage and communicates with the inner container.With the steam passage alone, the condensed water and the inflowing content liquid that may remain in the liquid reservoir portion without returning to the inner container, It can also be used to return to the inner container 2 as it is or when the container is tilted when it is poured out.

  In the above, the communication path may be further characterized by branching from the liquid reservoir portion to the spout side, and a communication port opening at the rear portion of the outflow port.

  In such a configuration, in addition to the above, further, the communication path branches to the inclined side of the container when the content liquid is poured into the liquid reservoir, and the condensed water remaining in the liquid reservoir It is convenient to return the inflowing content liquid into the inner container through the communication path with the inclination of the container at the time of pouring. In addition, the communication port of the communication path is located at the rear of the outlet of the pouring channel, and the content liquid poured out toward the outlet is difficult to reach due to the inclination of the container, and even if it extends, the communication path can reach the liquid reservoir. There will be no backflow.

  In the above, the steam detection part that detects boiling by touching the steam and turns off the heater is located on the opposite side of the liquid reservoir part from the branch side of the communication path so that the steam reaches from the liquid reservoir part. Can be characterized.

  In such a configuration, in addition to the above, the steam detector detects the boiling by touching the steam and turns off the heater, so that the power supply can be stopped at the time of boiling without requiring complicated control and circuit. The detection unit is located on the opposite side of the liquid reservoir from the branch side of the communication path, and is not affected by the condensed water or the inflowing content liquid that is returned from the liquid reservoir to the inner container through the communication path.

  In the above, the communication passage may be formed in a Γ shape.

  In such a configuration, in addition to the above, the form of the communication path is simplified, it is easy to form integrally, and the residual vapor is easily discharged to the liquid reservoir, and the condensed water remaining in the liquid reservoir and the inflow content It is easy to return the liquid into the inner container.

  In the above, the opening / closing mechanism may be characterized by opening and closing both the outlet and the communication port with one valve body.

  In such a configuration, in addition to the above, since the outlet and the communication port are opened and closed by one valve body, the valve structure is not particularly complicated, and regardless of the presence or absence of a step between the outlet and the communication port. In addition to simultaneous opening and closing, the opening operation preceded by the communication port can be realized by changing the fitting amount of the valve body at the closing position with respect to the outlet and the communication port.

  In the above, the steam passage may further include a water stop valve at the time of falling upstream of the liquid reservoir.

  In such a configuration, in addition to the above, when the body falls, in addition to preventing the outflow of storing the liquid in the liquid reservoir, the water stop valve at the time of falling works to close the steam passage and stop the water. Doubles outflow prevention function. In addition, the liquid reservoir is compatible with the fact that the content liquid does not flow in darkly by closing the upstream water stop valve, and the water stop valve at the time of falling does not stabilize at the water stop position until the fallen body settles down. It is only necessary to receive a small amount of content liquid leaking in a short time and prevent the liquid from flowing out to the outside, and it is easy to prevent the liquid from flowing out and return it to the inner container. In particular, even if the tilt angle of the body that closes the water stop valve at the time of falling is set small to enhance the water stop function at the time of falling, the communication path branched from the liquid reservoir becomes a bypass when the content liquid is poured out. The inside can be communicated with the steam discharge port to secure the intake air and does not hinder the extraction.

  Further features of the present invention will become apparent from the following specific description and drawings. Each feature of the present invention can be used alone or in combination with various combinations.

  According to the electric kettle of the present invention, the lid that closes the inner container through the seal member is led out from the inner container to the outside of the container through the pouring path and the steam passage, and the content liquid is poured out and the steam is discharged to the outside. However, when the content liquid is not being dispensed, the dispensing path is closed with an opening / closing mechanism, and even if the container falls over when it is not being dispensed, the content liquid will not flow out of the container, or when the steam passage is constantly open, After that, the generated steam is released to the outside to prevent the pressure inside the container, and even if the liquid content flows into the steam passage due to overturning of the container, it prevents or reaches the steam discharge port by storing in the liquid reservoir. Since the delay is made, it is possible to prevent the content liquid from flowing out to the outside in a large amount at an early stage through the vapor passage with a simple and low-cost structure without an operating part. In addition, the communication path branched from the liquid reservoir is not opened to the outlet side of the residual steam by the opening / closing mechanism, which is opened at the same time as or earlier than the outflow path and enlarges the area of the passage through the inside and outside of the lid. The user's safety can be improved by preventing preparation balloons and disturbing or disturbing the pouring. In particular, when the communication passage is opened in advance, the release of residual steam from the steam discharge port is further promoted before the discharge passage is opened, and the safety can be improved by preventing the discharge from the discharge port. In addition, if the steam passage alone is not returned to the inner container, the condensed water or the inflowing content liquid that may remain in the liquid reservoir is left in the inner container 2 as it is or when tilted when the container is poured out. As much as they can be used to return, measures are not required or are easier to take.

  In addition to the above, the communication channel branches off from the liquid reservoir to the inclined side of the container when the content liquid is being dispensed, and the condensed water and inflowing content liquid remaining in the liquid reservoir are removed. It is easy to return to the inner container along with the inclination. In addition, the communication port of the communication path is located at the rear end of the outlet of the extraction passage, and there is no problem that the liquid content poured out toward the outlet reaches.

  In addition to the above, the steam detector detects boiling and turns off the heater, eliminating the need for complicated control and circuitry, reducing product costs and the steam detector on the opposite side of the reservoir It is less susceptible to the influence of condensed water and inflowing content liquid that is returned to the inner container through the communication path, and electrical safety can be achieved.

  In addition to the above, the communication path is integrally formed in a simple Γ shape, which does not cause an increase in cost, and the residual vapor is discharged into the liquid reservoir, the residual condensed water in the liquid reservoir and the contents of the inflowing liquid The return to the vessel can be facilitated.

  In addition to the above, the outflow port and the communication port are opened and closed by a single valve body, the structure is not complicated and easy to clean, and the cost does not increase. Regardless of whether there is a step between the outlet and the communication port, not only simultaneous opening and closing, but also the opening operation preceded by the communication port depends on the difference in the amount of fitting between the valve body, the outlet and the communication port at the closed position, etc. Easy to implement.

  In addition to the above, the overflow function is doubled in the contents liquid at the time of falling of the body in both the case of falling of the body, the liquid reservoir, and the water stop valve at the time of falling, which is suitable for an expensive model. In addition, the liquid reservoir does not flow the content liquid darkly by closing the water stop valve at the time of tipping, and a small amount of content liquid that leaks out before the water stop valve stabilizes at the water stop position when the body falls. Since it is only necessary to accept and prevent the outflow to the outside, it is easy to prevent the outflow, and it is easy to return to the inner container. In particular, even if the body tilt angle that closes the water stop valve at the time of falling is reduced and the water stop function at the time of falling is increased by early closing, the communication path branched from the liquid reservoir is bypassed when the liquid is dispensed. By connecting the inside of the chamber to the steam outlet, air intake can be secured and there is no hindrance to pouring.

  Embodiments of the present invention will be described below with reference to FIGS. However, the present invention is not intended to limit the scope of the present invention to the following embodiments, but is merely an illustrative example, unless otherwise specified.

  In the present embodiment, as shown in FIG. 1, a container 4 in which a metal inner container 2 made of stainless steel or the like that is heated by a heater 1 is housed in a resin outer case 3, A lid 5 that closes the inner container 2 is provided at the upper end. Furthermore, a pouring path 6 for pouring the content liquid toward the upper end front of the container body 4, an opening / closing mechanism 7 for opening and closing the pouring path 6, and a water stop function at the time of falling that allows the steam to escape to the outside. A hand-held electric kettle that can be easily handled by providing a handle 9 on the container body 4. As a result, the inner container 2 that is a kettle container is covered with the outer case 3 so that the user does not touch it directly to cause hot feelings or burns, and the heat insulating property due to the outer case 3 being made of resin. Since the air insulation action between the inner container 2 and the outer case 3 is also helped and the temperature of the outer surface of the container body 4 can be suppressed, the thermal safety when touched is increased. Also, the heating efficiency is somewhat increased due to their heat insulating effect.

  Further, the inner container 2 is closed by the lid 5 and the content liquid can be poured out only when the pouring path 6 provided in the lid 5 is opened by the opening / closing mechanism 7, and the container body 4 falls down when not pouring including the time of boiling water. Even so, the outflow of the content liquid through the pouring channel 6 can be prevented. Further, the steam passes through a predetermined steam passage 8 provided in the lid 5, and a predetermined safe position on the predetermined path, specifically, the operation unit 11 from the outside of the lid 5 of the opening / closing mechanism 7 and the lid of the lid 5. 5 Since the discharge is performed at the rear portion of the lid 5 shown in FIG. 1, for example, away from the position where the external operation unit of the attachment / detachment mechanism 12 is provided from the outside, the discharge is unlimited from the spout 13 of the container 4 15 (a), FIG. 15 (a), FIG. 15 (a), and FIG. 15 (a) and FIG. 16 can prevent the liquid content from flowing out through the vapor passage 8 even if the container body 4 falls down.

  However, even if the attachment / detachment mechanism 12 is not essential, the use of the steam passage 8 having the operation mechanism such as the water stop valve 14 at the time of falling as described above causes an increase in the product cost, resulting in a low-cost model. It is difficult to adopt. Further, making the steam passage 8 darkly wide is disadvantageous for water stoppage at the time of overturning, and the content liquid 16 is easy to cool, and if it is handled with a narrow structure, it restricts the release of steam, especially at the time of pouring immediately after boiling. It is also conceivable that residual steam may be inadvertently blown out from the pouring path 6 at the same time as the pouring path 6 is opened, or disturbing or disturbing the pouring. Further, in the model provided with the overturn stop valve 14 as in the illustrated example, when the container 4 is tilted as shown in FIG. 16 and the content liquid 16 is poured out, the overturn stop valve 14 is closed, Since the intake through the vapor passage 8 is hindered, there is also a problem that the content liquid 16 cannot be poured out smoothly.

  In order to cope with these, in the present embodiment, the pouring path for pouring the content liquid from the outflow opening opened in the inner container to the pouring outlet directed toward the upper front end of the container, and the pouring path In the basic configuration that does not require the water stop valve 14 at the time of overturning provided with an opening / closing mechanism for opening and closing the steam and a steam passage for releasing the steam from the steam outlet, the steam passage 8 flows in when the body 4 falls down. The vapor passage 8 has a partially expanded liquid reservoir portion 8a so as to prevent or delay the content liquid 16 from being accumulated and reaching the vapor discharge port 47, and branched from the liquid reservoir portion 8a to the vapor passage 8. A communication passage 77 communicating with the communication port 77 a is provided in the inner body 2 in the lid 5, and the communication passage 77 is opened by the opening / closing mechanism 7 at the same time or earlier than the pouring path 6.

  As a result, the lid body 5 that closes the inner container 2 via the sealing member 21 allows the inside of the inner container 2 to be communicated to the outside of the container body 4 due to the function of the dispensing path 6 and the steam path 8, Although the steam is discharged to the outside, the pouring path 6 is reliably closed by the opening / closing mechanism 7 except when the content liquid 16 is poured, so that the container body 4 falls down when not pouring including the time of boiling water. However, the content liquid 16 does not flow out of the container through the extraction channel 6. Further, the steam passage 8 is always opened to discharge steam generated not only during boiling but also from the steam outlet 47 of the lid 5 to the outside, thereby preventing the pressure inside the container 4 from being increased. Even if the body 4 falls down and the content liquid 16 flows into the vapor passage 8, the content liquid 16 can be stored in the overturning liquid reservoir 8 a and blocked or delayed from reaching the vapor discharge port 47. Further, the communication passage 77 branched from the liquid reservoir 8 a and leading to the inner container 2 is opened simultaneously with or earlier than the outflow passage 6 through which the content liquid 16 is poured out by the opening / closing mechanism 7 and is parallel to the vapor passage 8. Then, since the inside of the inner container 2 communicates with the liquid reservoir 8a, the remaining steam is prevented from blowing out toward the spout 17 side by the amount that the passage area passing between the inside and outside of the lid 5 is enlarged, and the liquid in the steam passage 8 It is easy to flow into the reservoir 8a and discharge from the vapor discharge port 47 in a predetermined manner. In particular, when the communication path 77 is opened prior to the pouring path 6, it is possible to further promote the discharge of residual steam from the steam discharge port 47 before the pouring path 6 is opened. Further, the communication passage 77 branches from the liquid reservoir portion 8a of the vapor passage 8 and communicates with the inner container 2. Condensation that may remain in the liquid reservoir portion 8a without returning to the inner vessel 2 with the vapor passage 8 alone. The water or the inflowing content liquid can be used as it is or returned to the inner container 2 at the time of tilting as shown in FIG.

  As a result, the lid 5 is introduced from the inner container 2 to the outside of the container body 5 through the pouring path 6 and the steam passage 8 so that the content liquid 16 is poured and the steam is discharged to the outside. The discharge passage 6 is closed by the opening / closing mechanism 7 except when the container is discharged, and the liquid 16 does not flow out of the container 5 even when the container 4 falls over when the container is not poured. After that, the generated steam is discharged to the outside to prevent the pressure inside the container 4 from being increased, and even if the liquid 16 flows into the steam passage 8 due to the container falling down, the steam is released into the steam discharge 47 by the storage in the liquid reservoir 8a. Therefore, it is possible to prevent the content liquid 16 from flowing out to the outside in a large amount through the vapor passage 8 at an early stage with a simple and low-cost structure having no moving part. Further, the communication passage 77 branched from the liquid reservoir 8a is opened by the opening / closing mechanism 12 at the same time as the outflow passage 6 or earlier than that, and the passage area of the inside and outside of the lid body 5 is expanded to increase the passage area. The safety of the user can be improved by preventing inadvertent blowing to the side of the spout 17 and preventing or disturbing the spout. In particular, when the communication passage 77 is opened in advance, the release of residual steam from the steam discharge port 77 is further promoted before the discharge passage 6 is opened, and the safety by preventing the discharge from the discharge port 17 can be enhanced. Further, the communication passage 77 alone is not returned to the inner container 2 by the steam passage 8 alone, but the dew condensation water and the inflowing content liquid that may remain in the liquid reservoir portion 8a are used as they are or when the container 4 is poured out. Therefore, it is not necessary or easy to take measures for the amount that can be used for returning to the inner container 2 at the time of tilting.

  Further, the communication passage 77 branches from the liquid reservoir 8 a to the spout 17 side, and the communication port 77 is opened at the rear portion of the outflow port 15. As a result, the communication passage 77 branches to the inclined side of the container body 4 shown in FIG. 16 when the content liquid 16 is poured into the liquid reservoir 8a, and the condensed water remaining in the liquid reservoir 8a. Or the inflowing content liquid is convenient and easy to return to the inner container 2 through the communication passage 77 with the inclination of the container 4 at the time of pouring. In addition, the communication port 77a of the communication passage 77 is located at the rear of the outlet 15 of the pouring path 6, and the content liquid 16 poured out toward the outlet 15 as shown in FIG. Even if this occurs, the communication passage 77 does not flow back to the liquid reservoir, and the presence of the communication passage 77 is not a particular problem.

  In addition, since the communication path 77 is formed in a Γ shape, the form of the communication path 77 is simplified, and it is easy to be integrally formed with the lid member, which does not cause an increase in cost. In addition, it is easy to allow residual steam to escape to the liquid reservoir 8a, and it is easy to return the condensed water and inflowing content liquid remaining in the liquid reservoir 8a to the inner container 2, so that these measures are unnecessary and easy to take. Become.

  The opening / closing mechanism 7 opens and closes both the outlet 15 and the communication port 77a with a single valve body 84b. As a result, the outlet 15 and the communication port 77a are opened and closed by the single valve body 84b, so that the valve structure is not particularly complicated and does not cause an increase in cost, and the figure between both the outlet 15 and the communication port 77a. Regardless of whether there is a step or no step as shown in the example, not only simultaneous opening and closing, but also the opening operation preceded by the communication port 77a is fitted to the outlet 15 of the valve body 84b and the communication port 77a in the closed position It can be easily realized by changing the amount.

  In addition, it has a steam detection unit 26 that detects boiling by touching the steam and turns off the heater 1, and power supply can be stopped at the time of boiling without requiring complicated control and circuit, leading to cost reduction. In particular, the steam detection unit 26 is located on the opposite side of the liquid reservoir 8a from the branch side of the communication passage 77, so that the vapor reaches from the liquid reservoir 8a. As described above, the vapor detection unit 26 is positioned on the opposite side of the liquid reservoir 8a from the branch side of the communication passage 77, and the dew condensation water and the inflowing content liquid returned from the liquid reservoir 8a to the inner container 2 through the communication passage 77. The electrical safety can be achieved.

  In the illustrated example, the overturn stop water valve 14 is provided in the liquid reservoir 8a of the steam passage 8, and the steam passage 8 includes the overturn stop valve 14 upstream of the liquid reservoir 8a. As a result, when the container falls, in addition to preventing the outflow of storing the content liquid 16 in the liquid reservoir 8a, the stop water valve 14 operates to close the steam passage 8 and stop the water, thereby preventing the outflow of the content liquid 16 The function doubles. In addition, the liquid reservoir 8a does not flow in the content liquid 16 in the dark by closing the upstream water stop valve 14 and the water stop valve 14 is stable in the water stop position until the fallen body 4 is settled. It is only necessary to accept a small amount of the content liquid 16 leaking in a short time corresponding to not to prevent the outflow to the outside, and it is easy to prevent the outflow and return to the contents 2 container, so measures can be omitted Easy to take measures. In particular, even if the tilting angle of the vessel body 4 that closes the water stop valve 14 at the time of falling is set small to enhance the water stop function at the time of falling, the communication passage 77 branched from the liquid reservoir 8a when the content liquid is poured out is shown in FIG. (A) As shown in FIG. 16, it becomes a bypass and the inside of the inner container 2 is communicated with the vapor discharge port 47 so that intake air can be ensured and does not hinder the extraction.

  On the other hand, in the above configuration, it is not possible to maintain the form in which the container body 4 is not bulky, reduce the remaining amount at the time of pouring, and increase the volumetric efficiency. 1, FIG. 7, FIG. 8, FIG. 11, FIG. 5, the content liquid 16 is poured out from the outlet 15 opened in the inner container 2 toward the spout 17 toward the front upper end of the container 4. 12, an opening / closing mechanism 7 as shown in FIG. 1, FIG. 6, FIG. 7, FIG. 8, and FIG. A steam passage 8 as shown in FIG. 1, FIG. 15 (a), and FIG. 16 is provided. In addition, the inner container 2 has a cylindrical shape having a substantially straight body as shown in FIGS. 1, 15, and 16, and the sealing member 21 of the lid 5 is moved to a predetermined sealing position 2 a in the container body 4. The outlet 15 is opened in the vicinity of the body wall front portion 2b of the inner container 2 in a plan view in the region surrounded by the sealing member 21 of the lid 5. It is provided so that the front portion 15a of the edge is located.

  As described above, the inner container 2 has a cylindrical shape with a substantially straight body portion, and the sealing member 21 of the lid is closed by contact with the predetermined sealing position 2a from above. The mouth portion of the vessel 2 does not require the inner fitting with the shoulder portion 4a or the lid 5 side of the vessel body 4 or the inward wraparound, and the inner container 2 in the region surrounded by the seal member 21 of the lid body 5. Since the front portion 15a of the opening edge of the outlet 15 of the pouring channel 6 is located in the vicinity of the body wall front portion 2b in plan view, it is easier to make the space smaller than the preceding example. Only when the content liquid 16 is poured out, the remaining amount with respect to the tilt angle of the container body 4 can be made smaller than in the preceding example. When the container 4 is tilted to the horizontal, the remaining amount is as shown in FIG. 15A, and is smaller in each stage as compared with the preceding example of FIG. 15B.

  Further, the diameter of the upper end portion 2a of the inner container 2, that is, the inner diameter is the same as or substantially equal to the diameter of the trunk portion, and the seal member 21 of the lid 5 comes into contact with the predetermined seal position 2a from above. Along with the lid 5 that closes 2, the inside diameter of the body 4 becomes large, and the lid 5 has a pouring path 6, an opening / closing mechanism 7, and a steam passage 8 that satisfy the functions required for them, and is easily arranged in an integrated manner. Become.

  As a result, the inner container 2 having a substantially straight body is closed by abutment of the sealing member 21 of the lid 5 from above on the predetermined sealing position 2a, and the sealing member 21 of the lid 5 In the enclosed area, it is easy to bring the body wall front part 2b of the inner container 2 and the front phase 15a of the opening edge of the outlet 15 of the pouring channel 6 close to each other, and the remaining amount with respect to the inclination angle of the container 4 is as shown in FIG. As illustrated in FIG. 15A, the content is reduced, and the content liquid is efficiently discharged at a small inclination angle as compared with the preceding example illustrated in FIG. In addition, the lid body 5 that abuts the seal member 21 on the large-diameter upper end 2a, which is substantially the same as the body diameter of the inner container 2 and enhances the volumetric efficiency, becomes large without the bulkiness of the container body 4, so Satisfying that the pouring path 6, the opening / closing mechanism 7 and the steam passage 8 are centrally arranged to satisfy the functions required for the lid 5 without overlapping, that is, without being bulky. The part around can be made slimmer than the previous example.

  The sealing position 2a as described above may be a part of the opening 4b portion of the shoulder portion 4a of the container body 4 that is connected to the upper end of the inner container 2 from above, but as in the example shown in the drawing If the lid 5 is brought into contact with the upper end 2a of the upper end of the inner container 2 directly from above to close the inner container 2, the seal can be achieved. In order to ensure a more reliable and sealing property, an inner fitting part or an inner contact part to the upper end part 2a opening of the sealing member 21 having substantially the same diameter as that of the body part of the inner container 2 is provided. The front portion 15a of the opening edge of the outlet 15 provided in the lid 5 can be brought closer to the front portion 2b of the body wall of the inner container 2 without being protruded inward or wrapped around. In addition, when the upper end 2a of the inner container 2 forming the sealing position 2a is an outward flange 2a bent outward as shown in the drawing, the outward flange 2a has a wide contact with the seal member 21 abutting from above. Since the contact surface is provided and the sealing performance is further improved, it is preferable to eliminate the need for a sealing structure that projects and seals inside the upper end portion 2a in order to secure the sealing performance of the sealing member 21. Further, as shown in the figure, the outward flange 2a is supported on the step 4a1 below the opening 4b of the shoulder 4a from below via the seal packing 22 so that the inner flange 2 is fitted to the inner container 2 on the body 4 side. It is suitable to connect the both without.

  In this case, as shown in FIG. 1, the bottom part 42 and the contents are formed by applying the resin-formed bottom part 42 from below to the lower end of the body part 41 integrally molded with the shoulder part 4a and the body part 4c of the container 4. By connecting the bottom of the container 2 with the screw 23, the assembly of the container 4 can be easily performed and maintenance is also possible. Of course, fixing the heater 1 to the bottom of the inner container 2 is advantageous in terms of heating efficiency such as adhesion, and the internal power supply unit 24 to the heater 1 is externally fixed to the bottom 42 side. Conveniently, the power supply device 25 can be connected by direct fitting as shown in the figure. However, prior to the connection between the main body portion 41 and the bottom portion 42, the heater 1 side and the internal power supply device portion 24 need to be connected in advance, and the connection is between the unconnected main body portion 41 and the bottom portion 42. Therefore, a wiring length is required that enables operations such as connection release and parts replacement by separating both the main body portion 41 and the bottom portion 42.

  Further, the connecting structure in the vertical direction between the main body portion 41 and the bottom portion 42 is formed between a holding hole 41a opened downward on the main body portion 41 and a holding hole 42a opened upward on the bottom portion 42 as shown in the figure. In addition, the handle 9 can be sandwiched and assembled, and it becomes easy to provide the handle 9 on the container body 4, and it is possible to perform independent maintenance by removing it.

  For this purpose, the base 9a of the handle 9 to be attached to the body 4 needs to have a size and form extending from either the main body part 41 or the bottom part 42 to one side from these connecting parts. When the part is closer to the lower part of the body 4, a size and shape that are long in the vertical direction are suitable for satisfying it. In the illustrated example, an inner loop body 9b, a gripping portion outer peripheral wall 9c fitted to the gripping portion outer side, and a mounting base portion 9a outside so that the handle 9 and its mounting base portion 9a form a substantially rectangular loop. The steam detection is performed by the base outer peripheral wall 9d to be fitted, the steam is touched on the upper part to detect boiling, the power supply path from the internal power supply device 24 to the heater 1 is opened, and the power supply is cut off. A steam sensor 26 as a part 26 is built in, and this also serves as an on / off switch for power feeding. In this connection, the upper part of the handle 9 is provided with a steam introduction path 31 through which steam is introduced and brought into contact with the bimetal 26a portion of the steam sensor 26 from the steam passage 8 of the container body 4, and the steam that has touched the bimetal 26a is placed in the container. The body 4 side is U-turned, and has an inclined bottom surface 31a that returns the dew condensation water, and is formed so as to expand downward toward the body 4 side. A return path 32 formed in the attachment base 9a from the introduction path 31 is guided to the lower part of the handle 9, and flows out from an outlet 32a there. Here, the return path 32 is located near the container 4, and as shown in the drawing, the return path 32 around the slim body 4 c of the container 4 is closer to the inner container 2 than the other parts. By doing so, even if the condensed water flows down in the return path 32, it is easy to evaporate by the heat from the inner container 2, and it is possible to prevent the condensed water from going out and getting wet around. . For this reason, even if the temperature of the portion of the return path 32 rises to some extent, there is no fear that the hand holding the handle 9 will touch, and thermal safety is ensured.

  The discharge of the steam flowing into the steam sensor 26 part together with condensed water through the return path 32 in the unlikely event of condensate water is introduced from the liquid pool part 8a under the steam sensor 26 and makes a U-turn. Instead of flowing back to the 5 side, it passes through one side so as to be pulled out. As a result, the steam whose static pressure increases with the filling of the steam in the liquid reservoir 8a is diverted into the introduction path 31 over time by a predetermined amount based on the restriction by the partition wall 94 and brought into contact with the steam sensor 26. When the steam temperature reaches the boiling equivalent temperature, the steam sensor 26 can immediately react to enable the heater 1 to be turned off, while reducing the amount of steam entering the steam introduction path 31 and the return path 33. Condensed water is less likely to be generated while being limited to the limit, and even if it occurs, it can be easily diffused by heat from the inner container 2 side as described above.

  As shown in the figure, the connection between the steam sensor 26 and the power supply circuit to the heater 1 is performed by a lead wire 34 wired through a passage 33 provided in the gripping portion of the handle 9, so that the steam introduction path 31 and the return path 32 can be connected. Pull away, making it difficult for steam and condensed water to affect the wiring. In particular, in the vicinity of the steam sensor 26, the steam introduction path 31 and the passage 33 are partitioned by an attachment member 35 of the steam sensor 26 for further safety. In order to serve as an on / off switch for the heater 1, the steam sensor 26 has a passive member 26b that stabilizes the bimetal 26a with the leaf spring 36 in a position where the power supply circuit to the heater 1 is kept open and in a closed state. Then, the operation member 37 connected to the passive member 26b and the shaft 26c moves between the swing around the shaft 26c and the operation window 38 that exposes the operation member 37 to the upper rear side of the handle 9 as shown in FIG. The bimetal 26a is switched between the off position and the on position according to the position, and the operation member is used for detecting boiling by detecting the temperature of the steam. 37 is self-off. Such a vapor sensor 26 is a commercially available product.

  Here, as shown in FIGS. 1, 7, and 11, the opening / closing mechanism 7 is positioned in the vicinity of the rear side of the spout 17 for pouring the content liquid toward the front upper end of the container 4 of the lid 5. It is. Thus, since the opening / closing mechanism 7 is located in the vicinity of the rear side of the spout 17 of the lid body 5, the whole from the outlet 15 to the spout 17 of the spout path 6 that is opened and closed by the open / close mechanism 7 is covered by the lid. The space can be set close to the front side of the body 5, and the operation part 11 of the opening / closing mechanism 7 can be used as the vicinity of the spout 17 or the spout 13 connected to the spout 17, thereby enhancing the visual relevance of both. That is, since the opening / closing mechanism 7 is positioned in the vicinity of the rear side of the spout 17 of the lid 5, the entire portion of the pouring path 6 that is opened and closed by the open / close mechanism 7 from the outlet 15 to the spout 17 is the lid 5. It is possible to install a small space by approaching the front side, and it is advantageous for installation of other necessary equipment, and the operation part 11 of the opening / closing mechanism 7 is close to the spout 17 or the spout 13 connected to it as shown in the illustrated example. The high visual relevance of both makes it easy to use without misoperation.

Further, the steam passage 8 is provided on the rear side of the lid 5 opposite to the opening / closing mechanism 7,
It can be installed near the rear part of the lid 5 with little space, and can be sufficiently distant from the operation unit 11 to release steam to the outside. In this way, the steam passage 8 is located on the rear side of the lid body 5 opposite to the opening / closing mechanism 7 side that is frequently externally operated by the manipulator 11, and it is possible to enlarge the lid body 5. Even when it is discharged, it is kept away from the operation unit 11 sufficiently, and the safety of the user against steam can be achieved.

  In the example shown in FIGS. 1, 15, and 16, the metal inner lid 43 is provided on the lower side of the lower plate 71 where the outlet 15 of the lid 5 is opened. As shown in FIG. 4, the sealing member 21 provided around the peripheral wall 45 of the lid 5 is attached to the lid 5 by utilizing the fact that the resin lid 5 is thermally protected by being attached with screws 44 or the like. In addition to the sealing member 21 being sandwiched between the outer periphery of the inner lid 43 and the outer periphery of the inner lid 43, a valve chamber 46 is formed between the rear plate 71 of the lid 5 and the inner lid 43 at the time of falling. The water stop valve 14 is accommodated. The valve chamber 46 has a valve chamber upper part 46b having a valve port 46a located in the middle of the steam passage 8, a seating part 46c that is joined to the valve chamber upper part 46b from below to seat the stop valve 14 at the time of falling, and And a valve chamber lower part 46e having a steam inlet 46d around it, and the seating surface 46c1 of the seating part 46c is shaped like a mortar so that the stop valve 14 at the time of falling has the same shape and settles down. It is.

  As a result, when the body 4 is tilted to the extent shown in FIG. 16, that is, the tilt of the seating surface 46c1 is reversed with respect to the horizontal, the water stop 14 at the time of falling is along the tilt of the seating surface 46c1. It is possible to prevent the content liquid 16 from flowing out through the vapor passage 8 and to be closed more reliably by the dynamic pressure when the content liquid 16 arrives. If the valve chamber 46 is provided near the inside of the inner container 2 of the steam passage 8 as shown in the illustrated example, it is preferable that the content liquid 16 is prevented from flowing into an extra portion of the steam passage 8. However, providing the valve chambers 46 at a plurality of locations in the steam passage 8 can increase the chance of water stoppage.

  In the present embodiment, instead of providing a plurality of valve chambers 46, the steam passage 8 is caused by a delay in closing the stop valve 14 at the time of falling or the like on the way from the valve port 46 a to the steam discharge port 47 opening at the rear upper surface of the lid 5. The liquid reservoir 8a described above in which the steam passage 8 is partially expanded is provided by utilizing a dead space due to an increase in the size of the lid body 5 or the like, even if it flows into the valve port 46a after that. However, instead of this, it is possible to bypass the content liquid 16 that has flowed in due to the maze form so as not to reach the vapor discharge port 47 or to delay it.

  It should be noted that the above-described stoppage of the water stop valve 14 by the inclination of the seating surface 46c1 to the water stop position is performed in any direction around the axis, and the above-mentioned stoppage is performed regardless of the direction in which the body 4 falls. Water is achieved.

  Further, in connection with the provision of the inner lid 43, the inner lid 43 is provided with an outlet 15 of the inner lid 43 so as not to hinder the discharge of the content liquid 16 and the discharge of vapor as shown in FIG. 4. The corresponding range is provided with a communication hole 48 through which mainly the content liquid 16 to be dispensed passes, and a communication hole 49 through which mainly the discharge steam is passed around the valve chamber 46. In order to make it easy to pass, the number of communication holes 48 is extremely smaller than the number of the communication holes 48, and the internal solution 16 is restricted from reaching the valve chamber 46 when the container 4 falls.

  Moreover, the attachment / detachment mechanism 12 is provided between the opening / closing mechanism 7 of the lid 5 and the steam passage 8 as shown in FIGS. 1, 6, 10, and 11. Thereby, the attachment / detachment mechanism 12 of the lid 5 can be installed using the dead space 52 between the opening / closing mechanism 7 and the steam passage 8 in front and back of the lid 5, and the center position of the lid 5 in the front-rear direction Thus, the lid 5 can be easily locked on the side of the vessel 4 without being biased in position and locking force, and can be locked stably. Further, the lid 5 can be easily handled without being biased even when the lid 5 is attached and detached with the release of the lock.

  Specifically, the lid 5 is formed on the recessed portion 4d as shown in FIGS. 1, 3 and 9 formed above the step 4a1 at the lower part of the opening 4b of the shoulder 4a of the vessel 4 as shown in FIG. With a fitting with a certain amount of play, the attachment / detachment mechanism 12 allows the attachment / detachment. The above-mentioned fitting with play is a so-called plug fitting type in which both the lid 5 and the recessed portion 4d have a gentle inclination of a draft angle at the time of resin molding, are fitted in the axial direction, and are removed from the fitting. It is supposed to be removed.

  As shown in FIGS. 13 and 14, the attaching / detaching mechanism 12 for attaching / detaching the lid 5 individually exposes the thumb 61 and the index finger or ring finger 62 facing the thumb 61, as shown in FIGS. A pair of left and right engaging members 63 having outwardly operating pieces 63a, 63a adapted to be hung on the lid 5 are provided in the lid body 5, and the engagement of each engaging member 63 by a spring 64 acting between these engaging members 63 is provided. The joining piece 63b is configured to always protrude from windows 45a provided at two places on the left and right of the diameter line of the peripheral wall 45 of the lid 5. Opposing to this, there are locking recesses 65 in which the protruding engagement pieces 63b are engaged at two places on the diameter line of the peripheral surface of the recess 4d formed by the shoulder 4a of the vessel body 4 in FIGS. As shown in FIG.

  As a result, when the finger is put on the pair of left and right operation pieces 63a, the attachment / detachment mechanism 12 is received by the repulsive force of the spring 64 without retracting the engaging member 63 against the spring 64. Can be easily and stably gripped and can be handled freely. Therefore, the lid 5 can be gripped by the attaching / detaching mechanism 12 and can be plug-fitted in the axial direction from above to the recessed portion 4d of the container 4 as shown in FIGS. In the plug fitting intermediate attachment / detachment mechanism 12, the engagement piece 63b protruding from the peripheral wall 45 of the lid 5 abuts on the opening edge of the recessed portion 4d from above. However, the engaging piece 63b receives the pushing force toward the retreat side by the opening edge of the recessed portion 4d because the lower surface of the projecting portion is the inclined surface 63b1, and retreats against the spring 64 as shown in FIG. Be made. For this reason, the lid 5 can be further plug-fitted into the recessed portion 4d only by applying a light pushing force without any special operation. The plug fitting final stage lid 5 has its sealing member 21 pressed against the flange 2a at the upper end of the inner container 2 which is a predetermined sealing position on the side of the container 4 by a predetermined amount, and the inner container 2 is shown in FIGS. Close as shown in 2. Simultaneously with this closed state, the engaging piece 63b of the engaging member 63 faces the locking recess 65 on the inner surface of the recessed portion 4d as shown by the phantom line in FIG. Since it is released, it is projected again from the peripheral wall 45 by the spring 64 and engages with the locking recess 65. As a result, the engagement piece 63b prevents the lid 5 from being pulled upward by the flat upper surface being caught by the same flat lower surface of the locking recess 65, and the repulsive force of the seal member 21 causes the engagement portion 63b to be pulled out. The gap can be kept in the pressure contact state in the vertical direction. That is, the lid 5 can be locked in the closed state and stabilized in the vertical direction. However, the plug fitting to the recessed portion 4d of the lid 5 can be performed with the retraction of the pair of engaging members 63 by manual operation.

  Here, the locking recess 65 is designed so that the receiving amount of the engagement piece 63b is received at a push-back position that gives the spring 64 an appropriate compression state, so that the recess 4d has a play and is plug-fitted. Since the left and right centripetal function of holding the lid 5 being held at the neutral position where the spring force of the spring 64 balances left and right is exhibited, the lid 5 can be stabilized in the neutral position and the axial position in the left-right direction. In this connection, the spout 13 formed in the shoulder 4a of the vessel body 4 has a step 4d1 which is lowered toward the recessed portion 4d at the base as shown in FIGS. The spout 17 of the lid 5 is received and connected. As a result, the content liquid poured out through the pouring path 6 of the lid 5 flows from the pouring port 17 to the pouring port 13 and is poured out. 17 is small, and the lid 5 can be easily handled as a single unit, and the content liquid to be poured out by connection with the spout 13 can be poured out from a position away from the outer surface of the body part of the container 4 by a necessary amount. In addition, the fitting of the spout 17 with the stepped portion 2d1 exhibits a positioning function around the axis when the lid 5 is plugged into the recessed portion 4d from above, and at the end of the plug fitting, The function of preventing the body 5 from rotating around the axis is also exhibited. Accordingly, the lid 5 rattles around the axis, assuming that the engagement between the engagement piece 63b and the locking recess 65 has a moderate play for facilitating engagement / disengagement around the axis of the lid 5. This can be prevented.

  As shown in FIGS. 1, 13, and 14, the lid 5 is further fitted to the lower plate 71 having the lower plate 71 and the peripheral wall 45 from above, and shown in FIGS. The heater 1 is formed into a hollow shape by elastic engagement with the hook piece 81 and the locking portion 82 or the upper plate 70 screwed by the screw 72. In addition to the previously described vapor discharge port 47, the upper plate 70 includes an operation window 73 for exposing the operation portion 11 of the opening / closing mechanism 7 and an operation piece 63a of the attachment / detachment mechanism 12 as shown in FIGS. An attaching / detaching operation concave portion 74 that is protruded to perform the attaching / detaching operation, and a spout lid 70 a extending above the spout 17 and spout 13 are integrally formed. In addition to the valve chamber 46 described above, the lower plate 71 is interposed between the lower plate 71 and the intermediate plate 75 sandwiched between the upper plate 70 shown in FIGS. 1, 8, 11, and 12, as shown in FIG. 7, 8, and 12, the intermediate plate 75 is formed to form the pouring path 6 having the outflow port 15 and the pouring port 17, and the pouring portion inner lid 75 a that fits under the pouring portion lid 70 a. , And the auxiliary intermediate plate 76 shown in FIGS. 1, 6, and 11 sandwiched between the intermediate plate 75 and the upper plate 70 to form a steam passage 8 having a liquid pool 8a, and a pouring path 6 The communication passage 77 described above is formed adjacent to the rear portion.

  Here, in the attaching / detaching mechanism 12, the engaging member 63 is fitted to the connecting boss 70a as shown in FIG. 6 with the window 63c of its own as shown in FIG. In this state, it is sandwiched between the upper and lower plates 70, 71 and protrudes from the guide portion 8 b protruding upward from the liquid reservoir 8 a formed by the auxiliary intermediate plate 76, and the lower surface of the upper plate 70 so as to face this. The guide convex part 70b provided is guided from the left and right sides so that the cover body 5 is smoothly advanced and retracted so that the lid 5 is smoothly attached and detached with the unlocking. However, the guide on the front side of the engaging member 63 may use another part instead of the guide convex part 70b, for example, another structural protrusion, and depending on the case, it may be moved upward by the liquid reservoir 8a. It may be a protruding portion.

  Further, the opening / closing mechanism 7 is formed in a sliding hole 83 as shown in FIGS. 1 and 7A formed at a position concentric with the outlet 15 of the intermediate plate 75 as shown in FIGS. 1 and 7B. The valve shaft 84a is supported so as to be vertically slidable through two O-ring type seal members 85 at the upper and lower portions, and the outlet 15 is separated from and connected to the lower end valve body 84b of the valve shaft 84a through the seal member 86 from below. And a movable cam member 87 for opening and closing is rotatably connected to the valve shaft 84a of the valve 84 and is urged upward by a spring 88 to guide the vertical sliding of the movable cam member 87. As shown, a plurality of sets of fixed cams 91 are formed on the inner periphery of the guide cylinder 70c formed on the lower surface of the upper plate 70 so as to switch between opening and closing of the valve 84 in the circumferential direction. In addition to this, the outer periphery of the movable cam member 87 is radially overlapped. Each time the projecting movable cam 87a is engaged and the movable cam member 87 is pushed down against the spring 88, the valve 84 is opened as shown in FIG. Then, it is repeatedly switched to the rotational position where the holding of the opening is released and the valve 84 is closed as shown in FIG. Such a configuration has long been known as a so-called knock mechanism that switches between a protruding state and a retracted retracted state of a ballpoint pen, and is also known in Japanese Utility Model Publication No. 61-160831, and requires special features. Therefore, detailed illustration and description are omitted here.

  In the present embodiment, the outer peripheral engagement piece 11a is shown in FIG. 1 as the cap 11 having the operation portion 11 fitted to the movable cam member 87 so as to be relatively rotatable from above as shown in FIG. As described above, the movable cam member 87 is pushed down by engaging with the opening edge 73a of the operation window 73 from the inside, and the movable cam member 87 is pushed down, but the arc rotation of the movable cam member 87 at that time is affected. Not to be affected. Further, the valve 84 also prevents the rotation of the valve 84 by fitting the guide pin 84c integrally protruding on the valve body 84b with the guide hole 80 of the lower plate 71 shown in FIG. Does not affect the rotation of the machine, so that it is not affected. The seal member 86 provided on the valve body 84b is separated from and connected to the communication port 77a of the communication passage 77 adjacent to the outflow port 15, and is closed while the valve 84 is closed, that is, the discharge passage 6 is closed. The inner container 2 is closed during the pouring so that the inner container 2 is not discharged through a route other than the predetermined steam passage 8.

  In the plug fitting structure between the lid 5 and the recessed portion 4d of the container 4 as described above, the steam branched from the steam passage 8 and the reservoir 8a of the steam passage 8 is supplied to the steam sensor 26 built in the handle 9. The connection with the steam introduction path 31 as a leading steam path is connected at the same time as the plug fitting between the plug fitting region of the peripheral wall 45 of the lid 5 and the recessed portion 4d of the container body 4, and by releasing the fitting The connection is canceled. Such a connection is such that the steam is discharged mainly from a predetermined position by the steam discharge port 47 or the steam reliably reaches the steam sensor 27 part through the steam introduction path 31 so that boiling is detected without delay. Therefore, it is necessary to prevent the steam from leaking out at this connection portion. For this reason, in the present embodiment, as shown in FIGS. 1 and 18, the connection is made through the seal member 92, but even with such a connection through the seal member 92, the above-described seal member 21 and the flange are connected. It is more reliable to carry out the crimping in the axial direction in which the lid 5 is plug-fitted into the recessed portion 4d as in the crimping with 2a. However, as described above, the plug fitting region is a region in which the peripheral wall 45 of the lid 5 and the recessed portion 4d of the container body 4 are plug-fitted with some play, so that the axial direction, that is, the vertical direction It is difficult to provide a plane space for connection with direction crimping.

  Therefore, an attempt was made to use the axial crimping between the oblique surfaces using the draft described above in this plug fitting region, but allowing smooth plug fitting to the recessed portion 4d of the lid 5, In addition, it is very difficult to obtain a sufficient pressure-bonded state of the seal member 92 for sufficient sealing between the connecting portions.

Corresponding to this, in the present embodiment, as shown in FIGS. 1, 7, and 17, the lower portion of the vapor discharge port 47 at the rear of the lid 5 is set against the draft surface of the peripheral wall 45. The connection surface 45b which is inclined more greatly than the connection port 8c of the steam passage 8 is formed so as to penetrate the steam introduction port 31b corresponding to the connection port 8b. The connection port 4d2 is formed so as to protrude with a greatly inclined seal surface 92a, and the maximum initial value when the plug is fitted between the connection surface 45b and the seal surface 92a as shown in FIG. The lid 5 is plugged into the recessed portion 4d so that the connection surface 45b increases the axial overlap with the seal surface 92a while satisfying the relationship of gap G> pressure contact margin S, and the overlap amount is L. ₀ connection surface 45b from the time when the sealing surface 92 It begins to contact, connection surface 45b until the amount of overlap or later becomes the largest L ₁ is gradually pressed against the sealing surface 92a, to ensure a final pressure margin S to. With this final pressure contact allowance S, the connection ports 8c, 4d2 are connected to each other while securing the sufficient pressure contact of the seal member 92 at the same time as the plug fitting to the recessed portion 4d of the lid 5 is completed. Moreover, in the pressure welding for the pressure welding allowance S, the amount of pressure contact is increased while sliding only within a limited range of the remaining overlap L ₃ between the connection surface 45b and the seal surface 92a in the final stage of plug fitting. Therefore, since there is no catching and the sliding resistance does not work so much, the attachment of the lid 5 by plug fitting is easily achieved. Since the lid body 5 is extracted in a direction to reduce the pressure contact, it can be performed more easily.

  As shown in FIG. 17, the pressure contact allowance S is set uniformly between the connection surface 45 b and the seal surface 92 a, but this makes the inclination angle of the seal surface 92 a larger than the inclination angle of the connection surface 45 b. Then, when the pressure contact allowance S is set so as to gradually increase from the uppermost side to the lowermost side between the connection surface 45b and the seal surface 92a, it is possible to avoid or connect when the lid 5 is plug-fitted into the recessed portion 4d. While being advantageous in reducing the resistance, a firm connection can be obtained at the final stage.

  The connection port 4d2 is integrally formed outwardly with the peripheral wall 45, and is fitted into a vertical cylinder 4e that faces the upper end of the steam introduction path 31, and is connected to the steam introduction path 31 to be connected to the inner end of the elastic saddle pipe 93 The seal member 92 is integrally formed there. The seal member 92 has a seal lip 92b that protrudes toward the connection surface 45b and is curved toward the inner diameter side. The seal surface 92a is formed by a curved surface that is convex toward the connection surface 45b of the seal lip 92b. ing. As a result, the connection between the connection ports 8c and 4d2 via the seal member 92 is lighter, and is achieved in a sufficiently contacted state in which more annular contact continuity and sufficient contact surface width are ensured.

  By the way, the reaction force of the pressure contact due to the pressure contact allowance S between the connection surface 45b and the seal surface 92a is the engagement stop in the radial direction between the spout 17 of the lid 5 and the step portion 4d1 of the spout 13 of the vessel 4. The lid 5 is received by the function, and is stably held in the front-rear direction without the influence of the plug fitting with play with the recessed portion 4d, and the connection between the connection ports 8c and 4d2 via the seal member 92 is achieved. There will be no loosening or poor connection.

  In the steam passage 8, steam from the liquid reservoir 8 a substantially corresponding to the installation height range is provided between the steam discharge port 47 and the connection port 8 c, which are separated from each other in the rear part of the lid body 5. The partition wall 94 branched to the steam discharge port 47 side and the connection port 8c side is formed so as to face the lower side of the steam discharge port 47, and steam generated actively at the boiling stage has low ventilation resistance. It obstructs the escape to the steam discharge port 47 side, and it surely enters the steam introduction path 31 with the lower plate 71 under a predetermined limit, and the steam sensor 26 ensures boiling without delay. It is supposed to be detected. On the other hand, steam generated actively in a boiling state does not enter through the communication passage 77 on the side where the communication passage 77 is opened at the portion where the valve port 46 a of the steam passage 8 of the lower plate 71 opens upward. In addition, a Γ-shaped guide wall 95 as shown by an imaginary line in FIG. 1 that guides to the rear side of the lid 5 may be provided.

  Finally, as shown in FIG. 1, the container body 4 has a stationary surface 101 on the lower surface of the bottom portion 42. The stationary body 101 is installed on the power supply base 102 by the stationary surface 101, and an external power supply device provided there. 25 is connected to an internal power supply device 24 so that it can be heated by being supplied with power from a household power source connected to the power supply stand 102. After boiling, it is removed from the power supply stand 102 and carried by the handle 9, and can be moved to the required position. Can be used for repeated dispensing on the spot.

  If the power supply stand 102 is equipped with a power supply cord 103 connected to a household power supply together with the cord take-up reel 104 as shown in the example shown in FIG. Although illustration is omitted, it is preferable to have a stopper mechanism that performs winding by a spring force and stops at a predetermined drawing position, but is not limited thereto.

  The present invention is practically applied to a model equipped with a pouring path, an opening / closing mechanism for the pouring path, and a steam passage in the lid body. It is possible to prevent inadvertent blowout of residual steam through the route and obstruction of the pouring.
