Description

  The present invention is a liquid in which the content liquid stored in the container is led out to the outside through a lead-out path by pressing the air pump in the lid by a manual lever provided on the upper surface of the lid that opens and closes the upper end of the container. It relates to a container and is used, for example, for a household pot.

This type of liquid container is already known (for example, see Patent Documents 1 and 2). In the devices described in Patent Documents 1 and 2, when the manual lever is pulled up from the storage position in the lid, the operation transmission mechanism between the manual lever and the pressing lever below it causes a tension between the two levers. Thus, the operation transmission mechanism transmits the pressing operation of the manual lever to the pressing lever, and the pressing lever presses the air pump to pressurize the content liquid and guide it to the outside through the outlet path. When the two levers are interlocked in this manner, the push stroke of the air pump can be increased with a small stroke of the manual lever by combining the lever ratio, and a large amount of content liquid can be derived in one operation. In particular, the one described in Patent Document 1 discloses a lock member c that prevents the operation transmission mechanism a from transmitting the operation of the manual lever b to a pressing lever (not shown) as illustrated in FIG. The lock member c is provided on the side of the lid d so as to be movable between an untransmittable position where the operation transmitting mechanism a cannot be transmitted and a transmit position where the operation transmitting mechanism a can be transmitted as indicated by an arrow in FIG. ing.
Japanese Utility Model Publication No. 3-119327 Japanese Utility Model Publication No. 3-119341

  However, the operation transmission mechanism a transmits a pressing operation of the manual lever b, and is provided at the manual lever b itself or between the manual lever b and the pressing lever. In contrast, the lock member c is provided with an operation portion c1 on the side of the manual lever b. For this reason, the lock member c must be provided as a member that spans at least a wide range from the position of the operation portion c1 to the position of the operation transmission mechanism a on the manual lever b side. In addition, the operation portion c1 of the lock member c and the action portion that changes the state of the operation transmission mechanism a are positioned away from each other, and there is a problem that the operation is likely to be drowned and rattled, and it is difficult to operate smoothly. As described in Patent Document 1, it is necessary to guide both the left and right sides of the lock member c, and the structure becomes complicated and bulky. This increases the size of the lid and increases the cost.

  It is an object of the present invention to provide a liquid container that can be selected safely with a derivation safety member having a structure that is simple, small, easy to operate, and inexpensive with respect to the derivation operation by a lever, in a non-transmission state and a transmission state of the operation transmission mechanism There is to do.

  In order to achieve the above object, the liquid container according to the present invention is a liquid container accommodated in a container by pressing down an air pump in the lid by a manual lever provided on the upper surface of the lid that opens and closes the upper end of the container. In the liquid container in which the liquid is led out through the lead-out path, there are two transmission states, a transmission state in which the pressing operation of the manual lever is transmitted between the manual lever and the air pump, and a non-transmission state in which the transmission is disabled. One feature is that an operation transmission mechanism that adopts a state is provided, and a derivation safety member is provided on the manual lever to selectively take the transmission state and the non-transmission state of the operation transmission mechanism to prevent inadvertent derivation. Yes.

  In such a configuration, the derivation safety member works on the operation transmission mechanism located at the position related to the manual lever from the manual lever without any positional deviation from its immediate vicinity, and the transmission state and non-transmission state of the operation transmission mechanism can be selected. Even if the manual lever is pressed, as long as the non-transmittable state is selected, it is not transmitted to the air pump, and the content liquid can be prevented from being led out.

  In the liquid container of the present invention, the content liquid contained in the container is led out through the lead-out path by pressing the air pump in the lid with a manual lever provided on the upper surface of the lid that opens and closes the upper end of the container. The liquid container is provided with an operation transmission mechanism that takes two states, a transmission state in which a manual lever pressing operation is transmitted to the air pump side and a transmission impossible state in which transmission is disabled. Another feature is that a derivation safety member is provided for selectively preventing the transmission state and non-transmission state of the operation transmission mechanism to prevent inadvertent derivation.

  In such a configuration, in addition to the case of one feature, further, the derivation safety member works from the position closer to the operation transmission mechanism on the same manual lever than the manual lever without any positional deviation, so that the transmission of the operation transmission mechanism is performed. A state and a non-transmittable state can be selected.

In a further configuration, the lead-out safety member is provided inside the manual lever and is slid between the transmission state selection position and the transmission impossible state selection position by an operation unit facing the manual lever.
The derivation safety member can be selected between the transmission state selection position and the transmission impossible state selection position by sliding operation, and it is easier to place the operation part on the manual lever by placing it low in volume between the manual lever and the lid. It is provided as a thing.

The operation transmission mechanism is in an operation transmission state when the manual lever is pulled up from the retracted position to the lid by selecting the transmission state by the lead-out safety member, and transmits the pressing operation of the manual lever directly or indirectly to the air pump. As the manual lever is retracted, it is configured to return to or return to the non-transmissible state selection position, and the manual lever has been retracted with the derived safety member at the transmission state selected position on the surface of the lid facing the derived safety member. In a further configuration, when a cam portion is provided to return the derivation safety member to the transmission disabled state selection position
If the derivation safety member is in the transmission state selection position when the manual lever is lifted from the retracted position, the operation transmission mechanism changes from the non-transmittable state to the transmittable state and returns to the non-transmittable state as the manual lever is retracted. When the manual lever is retracted while the member is in the transmission state selection position, the lead-out safety member abuts against the cam portion of the lid and returns to the non-transmission state selection position side during the storage process, and the operation transmission mechanism transmits. Automatically corresponds to returning to the disabled state.

An upper end of the vent passage of the inner plug is detachably attached to the opening of the container body so as to be detachable with an inner passage provided with an air passage for pressurizing the content liquid by an air pump and an outlet passage for extracting the content liquid to be pressurized. In the further configuration, the opening and the air supply port from the air pump are positioned so as not to face each other in the sealing area between the inner plug side and the lid body side that contain them.
An internal plug device having a vent passage for pressurizing the content liquid by an air pump and a lead-out passage for deriving the pressurized content liquid while allowing supply and discharge of the content liquid through the opening to the container body It is possible to pressurize the content liquid by the air pump and lead it out through the lead-out path, and include the upper end opening of the vent passage of the inner plug and the air supply port from the air pump. In the sealing area between the inner plug side and the lid body side, even if the liquid contents may flow out from the upper end through the ventilation path due to overturning of the container, the outflow position does not face the air supply port Therefore, it is possible to delay the flow from the air supply port to the air pump until the water level reaches the air supply port while filling the seal area.

In the further configuration, the interval between the inner plug side and the lid side in the seal area is 3 mm or more, and preferably 4 mm or more.
When the interval between the inner plug side and the lid side in the seal area is less than 3 mm, when the content liquid reaches, it easily fills in the capillary phenomenon due to its surface tension and easily flows into the air pump, but exceeds 3 mm, Even better, if it exceeds 4 mm, such a situation can be avoided.

  According to one characteristic of the liquid container of the present invention, the derivation safety member works on the operation transmission mechanism at a position related to the manual lever from above the manual lever without any positional deviation, so that the transmission state and transmission of the operation transmission mechanism can be achieved. It is easy, small and low-cost, can be operated smoothly without wobbling or rattling, and even if the manual lever is operated based on the selection of the non-transmittable state, the contents liquid is not prepared It is possible to secure the derivation that prevents the derivation.

  According to another characteristic of the liquid container of the present invention, in addition to the case of one characteristic, the lead-out safety member works from the nearest position to the operation transmission mechanism located on the same manual lever with less misalignment from the nearest position. It is easier to operate, simpler, smaller and less expensive.

  The lead-out safety member can be selected between a transmission state and a non-transmission state by a slide operation, and is provided as a simpler one that is placed in a low volume between the manual lever and the lid so that the operation unit faces the manual lever. .

  When the manual lever is lifted from the retracted position, the operation transmission mechanism becomes in the transmission state according to the transmission state selection of the derivation safety member. When the manual lever is retracted, the lead-out safety member is automatically returned to the non-transmissible state selection position side by the cam portion of the lid, and the operation transmission mechanism automatically corresponds to the non-transmissible state.

  To supply and discharge the content liquid through the opening to the container, pressurize the content liquid through the vent passage of the inner plug attached to the opening, and lead out the pressurized content liquid through the outlet path. In the sealing area between the inner plug side and the lid side that contains the upper end opening of the air passage and the air supply port from the air pump, even if the contents liquid tries to flow out through the air passage due to overturning of the container, the outflow position is the air supply It is easier to take measures such as delaying the flow into the air pump until the water level reaches the air supply port without facing the mouth and raising the body during that time.

  The interval between the inner plug side and the lid side in the seal area is 3 mm or more, and more preferably 4 mm or more. Even if the content liquid reaches the seal area, it avoids the immediate filling of the capillarity due to the surface tension. The time for the water level to reach the air supply port can be surely delayed.

Hereinafter, embodiments according to the present invention will be described in detail with reference to FIGS. 1 to 8 for the understanding of the present invention. However, the following description is a specific example of the present invention and does not limit the content of the claims.

  This embodiment is an example of the case of a heat insulation pot used for heat insulation and cold insulation for home use, and includes a vacuum double container 1 made of metal, specifically stainless steel, as shown in FIG. The metal vacuum double container 1 is formed by combining a bottomed inner cylinder 2 and a bottomed outer cylinder 3 in an inner and outer double, and joining both mouths by welding or the like to form a common container mouth 1a. It is integrated into a double wall structure and has a sealing portion 4 in which the vacuum exhaust port is sealed with a sealing material while evacuating between the inner cylinder 2 and the outer cylinder 3, and a vacuum space 5 is provided between the double walls. As it is. A getter 6 as a gas adsorbent is attached to the inner wall surface of the vacuum space 5 so that the degree of vacuum can be maintained for a long time.

  The vacuum double container 1 is provided with a resin bottom member 7 and a shoulder member 8 as shown in FIGS. 1 and 5 on the bottom 1b and shoulder 1c shown in FIG. The portion 1d forms an outer surface, and the bottom member 7 constitutes a container body 12 that forms a stationary portion 11 to a stationary surface 9 such as a table. As shown in FIGS. 1 and 2, the vessel body 12 has a lid 13 that covers the upper end of the vessel body 12 formed by the shoulder member 8, and a container port 1 a of the vacuum double container 1 formed on the shoulder member 8. Through the opening 14 of the vessel body 12 connected to the evacuation unit 12 is provided with a lead-out path 15 for leading the content liquid stored in the vacuum double container 1 to the outside and an air pump 16 for pressurizing the content liquid and pushing it out from the lead-out path 15 to the outside. . The lead-out port 15a of the lead-out path 15 faces downward from the lower surface of the substantially central portion in the left-right direction of the projecting portion 17 projecting from the shoulder member 8 to the front.

  Thereby, the heat retaining pot of the present embodiment has a high heat retaining property by the metal vacuum double container 1 and a simple stationary in which the resin bottom member 7 and the shoulder member 8 are attached to the bottom 1b and the shoulder 1c. Durability in the mold body 12 and the position in the center in the front left and right direction of the upper part of the body 12 by the lead-out path 15 using the opening 14 of the container body 12 formed by the shoulder member 8 and the projecting portion 17 to the front part. Derivation path by derivation of the content liquid from the outlet port 15a and pressurization of the content liquid using the opening 14 of the body 12 of the shoulder member 8 by the air pump 16 on the lid body 13 side so as to be able to open and close the shoulder member 8 Derivation through 15 is realized, saving resources and energy and making it easy to use.

  1 and 2, for the purpose of derivation of the content liquid, a resin inner plug 18 is fitted into the opening 14 of the container 12 so as to be detachable from above, and a seal packing 19 is used. It sits tightly on the lip of the opening 14. The inner plug 18 is provided with a lead-out path 15, the lower end extends to the vicinity of the inner bottom of the vacuum double container 1, the inner plug 18 extends to a predetermined position of the overhanging portion 17, and the outlet 15 a is bent downward, It faces the bottom of the overhanging portion 17 through the bottom opening 21 of the overhanging portion 17. The lid 13 has a hollow structure made of resin and incorporates a bellows type air pump 16. The lid 13 is connected to the rear part of the shoulder member 8 so as to be opened and closed by a hinge pin 22. The air supply port 16 c formed on itself or on the lower surface of the lid body 13 is crimped to the upper surface of the inner plug 18 via a seal packing 24 and enters the vacuum double container 1 via an air passage 25 provided in the inner plug 18. The content liquid can be pressurized without air leakage.

  The content liquid in which the vacuum double container 1 is sealed can be kept warm, and the state in which the content liquid can be derivatized under pressure is on the side of the lid 13 shown in FIGS. 1 and 2 when the lid 13 is closed. The hook portion 27a formed integrally with the operation lever 27 pivotally supported by the shaft 26 is elastically engaged with the engaging portion 28 provided on the shoulder member 8 side as indicated by the broken line by the bias of the spring 29, and the lid 13 Is automatically locked in the closed state. The unlocking of the lid 13 to the closed position can be released by pushing the rear side 27b of the operating lever 27 against the spring 29 with an index finger or the like and rotating it clockwise around the shaft 26. The lid 13 can be rotated in the opening direction by pulling up the front part 27c of the operation lever 27 that gets up sometimes, such as by placing a thumb on it. As a result, the inner plug 18 can be removed from the opening 14 of the container body 12 together with the lead-out path 15 and washed, and the content liquid can be supplied and discharged through the opening 14 and the inside can be cleaned.

  Here, the air pump 16 is pressed by a manual lever 31 provided on the upper surface of the lid body 13 that opens and closes the upper end of the container body 12 as shown in FIGS. In order to lead out to the outside through the lead-out path 15, in particular, the transmission state shown in FIGS. 1 and 6 in which a pressing operation h of the manual lever 31 is transmitted between the manual lever 31 and the air pump 16 to the air pump 16 side. 2, an operation transmission mechanism 111 that takes two states, the transmission disabled state shown in FIG. 2, is provided, and the transmission state of the operation transmission mechanism 111 and the transmission disabled state are selectively taken on the manual lever 31. A lead-out safety member 33 is provided to prevent inadvertent lead-out. As a result, the lead-out safety member 33 operates from the immediate vicinity to the operation transmission mechanism 111 located at a position related to the manual lever 31 without being displaced from the manual lever 31 as shown in FIGS. 1, 2, 6, and 7. The transmission state and non-transmission state of the operation transmission mechanism 111 can be selected, and even if the manual lever 31 is pressed, as long as the non-transmission state is selected, it is not transmitted to the air pump 16 and the liquid content is prevented from being derived. can do. Accordingly, the derivation safety member 33 works on the operation transmission mechanism 111 at the position related to the manual lever 31 from the position on the manual lever 31 without any misalignment from the nearest position, and the transmission state and non-transmission state of the operation transmission mechanism 111 can be selected. Simple, small and low-cost, can be operated smoothly without wobbling or rattling, and prevents inadvertent derivation of content liquid even when the manual lever 31 is operated based on the selection of the non-transmittable state Derivation safety can be achieved. If the transmission state is selected, for example, as illustrated in FIG. 6, when the manual lever 31 is pulled up from the storage position indicated by the solid line to the virtual line position and then pressed as indicated by the broken line, the operation transmission mechanism 111 is responsively transmitted to the air pump 16 and pressed as indicated by a broken line, so that the content liquid is pressurized and led out to the outside through the lead-out path 15.

  Further, the operation transmission mechanism 111 includes a transmission state by the lead-out safety member 33 such as a press mediating member 34 pivotally supported by the support shaft 35 as shown in FIGS. 1, 2, 6, and 7 on the manual lever 31. By accepting the selection of the non-transmittable state, the derivation safety member 33 works from the manual lever 31 to the operation transmission mechanism 111 on the same manual lever 31 without any positional deviation from the nearest position. The transmission state 111 and the transmission impossible state 111 can be selected. Therefore, the derivation safety member 33 works from the nearest position to the press mediating member 34 of the operation transmission mechanism 111 on the same manual lever 31 from the manual lever 31 without any misalignment from the nearest position, so that the operability is better and the operability is simpler and smaller. And cheap.

  1, 2, and 6, the lead-out safety member 33 is provided inside the manual lever 31, and the operation portion 33 a that faces the manual lever 31 through the window 31 e is illustrated in FIGS. 1 and 6. Since the slide operation is performed between the transmission state selection position shown in FIG. 2 and the non-transmission state selection position shown in FIG. 2, the derivation safety member 33 can select the transmission state and the transmission impossible state by the slide operation. As shown in FIGS. 1, 2, and 6, a small space S between the lever 31 and the lid body 13 is disposed so as to be less bulky, and is provided as a simpler one that allows the operation portion 33 a to face the manual lever 31. It is done. With respect to the transmission state selection position and the non-transmission state selection position of the derivation safety member 33, the upward convex portion 33d of the front end of the derivation safety member 33 is elastically engaged with the engagement concave portions 31g and 31f provided on the front and rear of the lower surface of the manual lever 31. Thus, the elastic engagement release and the elastic engagement at the time of selection change can give a click feeling to the switching operation so that the user can clearly recognize the switching start and switching end.

  The operation mechanism of the air pump 16 will be described in further detail. As shown in FIGS. 1, 2, 6, and 7, the manual lever 31 is a lid body together with the operation lever 27 at the center in the left-right direction of the front portion of the lid body 13. In the recess 13 a formed to extend in the front-rear direction at the center in the left-right direction on the upper surface of the upper surface 13, the rear end of the operation lever 27 extends to the rear portion of the lid body 13, and the rear end portion is raised and lowered to the lid body 13 by the support shaft 32. It is urged so that it is in the retracted state shown by the solid line in FIGS. 1, 2, and 6 by the retracting return spring 30 that is pivotally supported and acted around the support shaft 32. As shown in FIG. 7, the manual lever 31 has an arcuate shape in the width direction facing left and right, and the pins 31a on the side walls formed on both sides of the rear half of the manual lever 31 are formed on the side walls of the lead safety member 33 having a channel shape. It is held in a space S formed with the lid 13 so that it can be fitted in the hole 33b and slid in the front-rear direction. As shown in FIGS. 1, 2, and 5, the front end, which is the free end of the manual lever 31, is easy to hang a finger as a handle 31 c that protrudes from the upper surface of the operation lever 27 and the lid 13 in an arc shape. Further, a stopper 31d that protrudes downward toward the free end of the lower surface of the manual lever 31 is integrally formed. By abutting against the stopper receiver 13b on the upper surface of the lid 13, it is excessively moved downward by an external load or the like. The transmission mechanism 111 is not damaged.

  As shown in FIG. 6, when the manual lever 31 is lifted to the maximum from the solid line position to the virtual line position against the spring 30, the lead-out safety member 33 on the manual lever 31 is On the condition that the rear end portion 33c is disengaged from the engagement portion 34c of the press mediating member 34 on the manual lever 31, it is not obstructed by the lead-out safety member 33, as shown in FIG. From the retracted position along the manual lever 31 indicated by the solid line, the tip end 34a hangs around the support shaft 35 on the manual lever 31 as shown by the phantom line and the broken line, and is in a state of stretching toward the air pump 16 side. Is transmitted directly or indirectly to the air pump 16 so as to be able to lead out the content liquid. Specifically, the tip part 34a depending on the press mediating member 34 is engaged with the air pump 16 by dropping the rear end part onto the engagement recess 36a on the upper surface of the press lever 36 supported by the support shaft 37 on the air pump 16, When the manual lever 31 is pushed down from the phantom line position to the broken line position, the pressing mediating member 34 is configured to stretch between the manual lever 31 and the pressing lever 36. As a result, the pressing mediating member 34 transmits the pressing operation of the manual lever 31 to the pressing lever 36, and the pressing lever 36 is moved downward about the support shaft 37 to the lid 13 so that the air pump 16 is shown as a broken line from the solid line. The internal air is fed into the vacuum double container 1 through the inner plug 18 to pressurize the content liquid, and can be led out through the lead-out path 15. By combining the two lever ratios as described above, a large pressing stroke of the air pump 16 is realized by a small pressing stroke of the manual lever 31, and a large amount of content liquid can be derived by a single pressing operation of the manual lever 31. Become.

  The air pump 16 has a restoring spring 16a that automatically recovers when the pressure is released. However, the air pump 16 expands while sucking outside air from the air inlet 16b at the center of the top plate, and is accompanied by the manual lever 31 and the operation transmission mechanism 111. Return. If the pressing operation by the manual lever 31 is repeated after waiting for such return, the content liquid can be repeatedly derived.

  In order to store the manual lever 31 after finishing the operation of deriving the content liquid, in the state shown by the phantom line in FIG. 6, as the leading end portion 34a of the press mediating member 34 hangs down, the manual lever 31 protrudes through the window 31h. It is only necessary to operate the upper end portion 34b rearward, whereby the press mediating member 34 is rotated clockwise around the support shaft 35 so that the tip end portion 34a is on the air pump 16 side, specifically, the engagement recess of the press lever 36. Since the engagement with 36 a is released and the tension between the manual lever 31 and the pressing lever 36 is released, the manual lever 31 is returned to the storage position by the bias of the storage return spring 30. Accordingly, the pressing mediating member 34 is automatically returned to the storage position along the lower surface of the stored manual lever 31 while the front end 34 a slides in the recess 13 a of the lid 13. Therefore, after the manual lever 31 and the press mediating member 34 are returned to the storage position, the lead-out safety member 33 is slid from the transmission state selection position from the left shown in FIG. 6 to the transmission impossible state selection position from the right shown in FIG. Then, even if the lead-out safety member 33 is engaged with the engaging portion 34c of the press mediating member 34 as shown in FIG. 2 and the manual lever 31 is pulled up from the retracted position to the virtual line position in FIG. Is held in the retracted position, and does not stretch between the air pump 16 side and therefore the pressing lever 36, and is not transmitted to the air pump 16 side even if the manual lever 31 is pressed. That is, it is possible to return to the state where the transmission disabled state is selected. Thereby, the content liquid is not derived by an inadvertent operation by an unintelligible person such as an infant.

  By the way, as shown by the phantom line in FIG. 6, when the manual lever 31 is pulled up and the pressing mediating member 34 is stretched and stable with the pressing lever 36, the handle 103 is moved to the phantom line when carrying the electric pot. If this happens, the manual lever 31 may be pushed down by the handle 103 and the content liquid may be inadvertently derived. Therefore, a portion or member protruding on the manual lever 31, in this example, the upper end 34 b of the press mediating member 34 is extended upward as indicated by reference numeral 34 a 1 to receive the handle 103, so that it does not occur any more. By doing so, such a worry can be easily avoided.

  In the present invention, the type of the body, therefore, the presence / absence of the heat retaining function, the presence / absence of the outer case, whether or not it has a heating function as disclosed in Patent Documents 1 and 2, whether or not the electric pump is used, The present invention can be applied regardless of whether it is inside or outside the body. However, when adopting the pressurization and derivation method of the content liquid using the inside plug 18 as in the present embodiment, the inside of the inside plug 18 Is provided with a check valve 81 that is normally open due to its own weight located in the middle of the outlet passage 15, and is closed by its own weight or the dynamic pressure of the liquid flow when the container body 12 rolls over, and the content liquid is externally passed through the outlet passage 15. I try to prevent it from leaking. Further, the vent passage 25 of the inner plug 18 exhibits a steam vent function for discharging steam to the outside through the air pump 16 and the intake port 16b, but also serves as a passage through which the content liquid flows when the container 12 rolls over. However, when the content liquid flows out, it flows into the air pump 16 and hardly returns. For this reason, in the example shown in the figure, the air passage 25 in the inner plug 18 is opened on the lower surface of the inner plug 18 by a throttle hole 25a that is restricted to the minimum diameter in terms of ventilation resistance, and the passage when the content liquid flows out. While restricting the outflow by utilizing the fact that the liquid resistance is higher than the ventilation resistance, the upper end of the inner plug 18 opens on the upper surface by a bowl-shaped passage 25b that provides a flow path that bends sideward and upward sequentially, The upper surface of the inner plug 18 and the lower surface of the lid body 13 face the seal area 101 that is expanded laterally by the seal packing 24, and the air supply port 23 on the lower surface of the lid body 13 is shifted in the lateral direction so as to face each other. ing.

  As a result, when the vent 12 is partly submerged in the content liquid when the container 12 rolls over, the content liquid tends to flow out through the vent 25, but first flows into the vent 25 through the throttle hole 25a. It is possible to prevent the air from flowing into the air passage 25 at once. Further, even if the content liquid flows into the vent passage 25 and tries to flow out to the upper surface of the inner plug 18, it takes time to flow out into the seal region 101 due to two collisions and changes in the vertical passage 25b. Even if it flows into the seal region 101, the vertical passage 25b and the air supply port 16c on the lower surface of the lid 13 are misaligned, so that the air supply port 16c is submerged in the content liquid flowing into the seal region 101. It is delayed from flowing into the air pump 16 from the air supply port 16c until it collects in the air.

  In this sense, it is essential that the space interval of the seal area 101 is not filled with liquid due to capillary action. In the illustrated example, the interval is set to about 3 mm, but is preferably set to about 4 mm or more. As the number of times increases, the inflow to the air pump 16 is delayed. However, if it is too wide, the heat-insulating pot will be too high.

  As a result, it takes a long time for the content liquid to flow into the air pump 16 from the rollover of the container body 12, so that sufficient measures can be taken to raise the container body 12 until then. In particular, there is sufficient time margin for rollover during handling. The vacuum double container 1 is a narrow-mouthed type in which the container mouth 1a is less than ½ of the body diameter due to the narrowed shape that passes through the shoulder 1c from the body 1d, and suppresses the heat from coming out to the upper part. 4 and 7, between the bottom member 7 and the bottom 1b of the vacuum double container 1, between the shoulder member 8 and the shoulder 1c of the vacuum double container 1, and the internal space of the inner plug 18 The heat insulating effect is further enhanced by accommodating the heat insulating material 104. On the diameter line of the shoulder member 8 in the left-right direction, both end portions of a resin U-shaped handle 103 are pivotally supported so as to be raised and lowered.

  In the present embodiment, since the outer surface of the container 12 is formed by the body portion of the vacuum double container 1, a liquid amount display portion 41 protruding from the outer surface is provided as shown in FIGS. However, the body 12 has a smooth rising shape from the outer surface of the body 12 at a position close to the left or right of the front part of the body 12, or the both sides of the body 12 do not have rising stepped portions. 12 is provided so as to protrude from the outer surface of the liquid quantity display section 41. The liquid quantity display section 41 has a built-in liquid quantity display pipe 42 with at least a lower end communicating with the bottom 1b of the vacuum double container 1. Thereby, with the liquid amount display by the easy-to-see liquid amount display unit 41 protruding from the outer surface of the container body 12, the above-described high heat retention and durability in the simple stationary container body 12 with a small number of parts, Derivation of the content liquid from the front left and right central portion of the upper part of the body 12 and derivation by pressurization of the content liquid by the air pump 16 on the lid 13 side are realized, saving resources and energy, and being convenient for use It becomes.

  In particular, the liquid amount display part 41 protrudes from the outer surface of the container body 12, but protrudes in a smooth raised shape of the container body 12, or both sides from the outer surface of the container body 12 without having a rising step part, A complicated detail portion is not formed between the outer surface of the container 12 and around the liquid amount display portion 41 itself, so that it is difficult to get dirty, and can be easily removed even if dirt is attached. Moreover, although the liquid amount display part 41 protrudes from the outer surface of the container body 12, it is located close to one of the front part left and right direction of the container body 12, and the outlet port is located at the center part of the front part left and right direction of the container body 12. Since the position is shifted to one side in the left-right direction with respect to 15a, it is difficult to be used for receiving the discharged liquid from the outlet 15a by a container such as a cup, and the container is difficult to touch or collide. So it is easy to ensure safety from external loads.

  Further, since the liquid amount display section 41 has a built-in liquid amount display tube 42 and protrudes from the outer surface of the container 12, the entire liquid amount display tube 42 can be viewed from the outside. However, if the viewing angle from the outside around the liquid amount display tube 42 is visible from a wide area of about 180 ° at the protruding position from the outer surface of the container 12 in the liquid amount display portion 41, the left and right sides of the container 12 are Compensating or reversing the retraction by the amount offset to one of the directions, the viewing angle from the left and right other side of the body 12 is not impaired, or the impairing angle is reduced, It is convenient because the amount of liquid can be confirmed from a wide area. Accordingly, the viewing angle of the liquid amount display tube 42 is preferably set to approximately 180 ° or more. Even if the viewing angle is less than 180 °, there is no particular inconvenience in use, and a viewing angle of approximately 160 ° or more is sufficient for practical use. It can be said that it is visible from a wide area.

  As shown in FIG. 5, the liquid amount display unit 41 includes a liquid amount display tube 42 and a cover body 43 that covers the liquid amount display tube 42 with a liquid amount display window 41a for visually recognizing the liquid amount display tube 42 from the outside. 43 is composed of a base member 44 on the side of the container 12 and a cover member 45 fitted to the front side of the base member 44, and the base member 44 and the cover member 45 have upper and lower ends at the bottom member 7 and the shoulder member 8. I try to keep it. The liquid level display unit 41 thus configured can project the liquid level by projecting to the outer surface of the container 12 without a detail portion with a simple and low-cost structure including only the liquid level display tube 42 and the cover body 43 covering it. The cover body 43 has a split structure of a base member 44 on the side of the container body 12 and a cover member 45 fitted to the base member 44 from the front side. 42 can be covered and protected, and the bottom member 7 and the shoulder member 8 are used to hold both the upper and lower ends without any special member, which does not cause an increase in cost. In addition, since the base member 44 of the cover body 43 provides a patterning surface for clarifying the liquid level in an open state, such a pattern is provided on the inner surface of the cover body 43 directly facing the back portion of the liquid amount display tube 42, That is, the liquid level can be made clear by simply providing the base member 44 on the patterned surface that is the front surface in the open state, and the base member 44 does not have to be transparent.

  In the present embodiment, the base member 44 is made of an opaque resin, the cover member 45 is made of a transparent resin, and the decorative edge 41b that forms the liquid amount display window 41a is formed on the cover member 45 by opaque printing or a film. Such a decorative edge 41b is preferably provided on the inner surface of the cover member 45 in order to prevent peeling off. Due to such a liquid amount display structure, in the illustrated example, the viewing angle around the liquid amount display tube 42 is slightly less than 180 °. Further, the base member 44 and the cover member 45 have a slide fitting portion that fits in the vertical direction, and the base member 44 and the cover member 45 are slid and fitted in the longitudinal direction. By combining, a cover body 43 can be formed and covered around the liquid amount display tube 42 to be protected. As described above, the cover body 43 is divided into two members, the base member 44 and the cover member 45. However, the cover body 43 becomes a stable integral body by the long slide fitting at the slide fitting portion 46 in the longitudinal direction. At that time, it can be handled as one cover body 43.

  The cover body 43 in which the base member 44 and the cover member 45 of the liquid amount display section 41 are slidably fitted to assemble the liquid amount display section 41 and the container body 12 is a vacuum double container as shown in FIG. 1 is fixed to approximately three places in the circumferential direction by welding to the bottom 1b and the bottom member 7 that is fixed to the mounting bracket 55 by screws 56 from the outside to the mounting bracket 55 that is fixed to the circumferential portion 1b. The upper and lower ends are sandwiched between the mounting member 57 and the shoulder member 8 screwed by the screw 58 and pressed against the outer surface of the container body 12, so that the outer surface of the container body 12 is also supported and firmly held. The For this holding, the cover member 59 separately formed as a part of the bottom member 7 and the shoulder member 8 and applied from the lower side to the overhanging portion 17 of the shoulder member 8 faces the liquid amount display portion 41 outward. It has pocket portions 7a and 8a which have a continuous shape and are stepped on the upper and lower ends of the cover body 43 between the outer surface of the body portion 1d of the vacuum double container 1 and thus the outer surface of the container body 12. The tenon part which was made thin through is inserted and held.

  The shoulder member 8 extends along the outer periphery of the container 12 from the outer peripheral rising peripheral wall of the dish-shaped part 8b and the dish-shaped part 8b that rises after extending from the portion of the container 12 where the opening 14 is formed. And the skirt wall 8c is applied to a stepped portion provided on the outer periphery of the shoulder 1c of the vacuum double container 1 so that the screw is fixed to the vacuum double container 1. The projecting portion 17 projects forward from the skirt wall 8c, and the cover member 59 is disposed on the projecting portion 17 and the skirt wall 8c in the circumferential direction corresponding to the projecting base portion. It is fitted with an internal fit to the peripheral wall and is clamped between the shoulder member 8 and the shoulder 1c of the vacuum double container 1 by screwing the shoulder member 8 to the vacuum double container 1 Yes. Here, the cover member 59 forms the bottom of the overhanging portion 17, and the outlet 15 a is formed in the cover member 59. Further, the opening 14 of the vessel 12 formed by the shoulder member 8 and the lower side of the container opening 1a of the vacuum double container 1 are applied to the container opening 1a via the seal packing 71, and the container opening 1a and the opening 14 A resin mouth ring 72 is provided to connect the two.

  In the above example, the derivation safety member 33 is manually operated to return the derivation safety member 33 from the transmission state selection position to the non-transmission state selection position. However, such a return operation is performed after the content liquid derivation operation. Can be forgotten, but if this happens, the derivation cannot be secured. Therefore, in the example illustrated in FIG. 8, the operation transmission mechanism 111 is in the transmission state when the manual lever 31 is pulled up from the storage position in the lid 13 by the selection of the transmission state by the derivation safety member 33, and the manual lever 31 Is transmitted directly or indirectly to the air pump 16 and returns to the non-transmittable state selection position when the manual lever 31 is retracted, or the return surface of the lid 13 is opposed to the safety member 33 by using the returned relationship. Therefore, in this example, the cam portion 13c is provided in the recess 13a to return the derived safety member 33 to the non-transmittable state selected position when the derived safety member 33 is in the transmission state selected position and the manual lever 31 has been stored. As a result, when the manual lever 31 is pulled up from the retracted position, if the safety member 33 is in the transmission state selection position, the operation transmission mechanism 111 changes from the non-transmittable state to the transmit state, and cannot be transmitted as the manual lever 31 is retracted. However, when the manual lever 31 is stored while the derivation safety member 33 is in the transmission state selection position, the derivation safety member 33 contacts the cam portion 33c of the lid body 13 during the storage process and the transmission impossible state is selected. Returning to the position side automatically corresponds to the operation transmission mechanism 111 returning to the transmission impossible state, and engages with the engaging portion 34c of the press mediating member 34. Therefore, forgetting to return the derivation safety member 33 to the transmission disabled state selection position is avoided, and derivation safety can be ensured.

  The present invention is practically used for household pots, and the transmission and non-transmission state of the operation transmission mechanism for the lever operation for deriving the content liquid is selected with a simple and small derivation safety member that is easy to operate and inexpensive. The safety of derivation can be achieved.
