JP 2003-144338 A

However, in the heat retaining bottle described in Patent Document 1, the entire inside of the large diameter attached to the mouth of the bottle body is used as a content liquid outlet path, and the large lower end opening and upper end opening are formed by a valve and a lid. Since it is a simple single structure that only closes, the heat in the bottle body easily escapes to the top through the stopper, resulting in low heat retention. In addition, the larger the liquid content, the more easily it is disturbed by the valve support and the operating member because it passes through a wider area in the plug body. There is a problem that is easy to be done. Furthermore, since the operation pieces of the locking member are positioned at two places on the diameter line of the lid body and are operated to slide on the lid body using the anti-slip on the upper surface, the thumb and forefinger, ring finger, and other opposing fingers It is difficult to operate individually simultaneously, and it is not suitable for pinching, and it is difficult to use the operation part to continuously remove the unlocked lid continuously with the unlocking operation. It is difficult and difficult to use.

  In view of the above problems, an object of the present invention is to provide a heat retaining bottle that can be used safely without incomplete assembly of a stopper that can be disassembled and that can improve heat retaining properties.

  In order to achieve the above object, the heat retaining bottle of the present invention is mounted on the bottle body having a heat insulating structure and the mouth of the bottle body so as to be detachable from above, and allows the content liquid to flow from the inside of the bottle body. A lead-out portion that pours out from the spout, and a valve body that closes the inlet of the lead-out portion, and an outer plug that plugs the mouth portion, and is detachably attached to the outer plug. It is attached so that it can be attached to the outside of the mouth of the bottle body from above, an inner stopper that locks the inner stopper in a state where it is attached to the outer stopper, an operation section that opens the valve body, and And a cup-shaped cap that covers the inner plug, the outer plug, and their equipment members, and the valve body and the lid have a closing behavior and are opened by the operation unit and are held in the opened position. When the cap is floating from the mounting position, When the valve is in the open position, it is pushed back to the closed position by mounting the cap. In both cases, the inner plug is pushed into the outer plug and the valve It is characterized in that the return from the open position to the closed position is performed by a single attachment of the cap.

  In such a configuration, the mouth part of the bottle main body is in a plugged state in which the outer plug itself attached so as to be detachable has a lead-out part and a valve body that closes the inlet of the content liquid of the lead-out part. The inner plug that is attached so that it can be attached to and detached from the outer stopper locks the outer plug and puts the outer plug in a stable plugged state, but there is a deficiency in the mounting of the inner plug to the outer plug because they can be separated and washed together. When the cap is attached to the mouth of the bottle during regular holidays, the cap is pushed to the position where it is attached to the cap, and the cap is plugged. It is returned to the closed position by mounting, and in both cases, the cap is pushed into the outer plug and the valve body is returned from the open position to the closed position by one mounting of the cap. Even if is removed, the liquid content will not leak.

In addition to the another feature, the lid contact portion may be further located on the cap side than the inner plug contact portion.

  The lid may be positioned on the side closer to the cap than the contact-related portion of the operation knob portion in the closed position.

  The valve body closes the inlet of the outlet chamber that opens to the bottom of the outer plug and the outside air inlet between the lower end of the outer plug, and the inner plug has a bottom that enters the operation chamber from above, The introduction port may be configured to introduce outside air from an outside air introduction port provided on the peripheral wall of the outer stopper through a gap between the peripheral wall and the inner periphery of the mouth of the bottle.

According to the characteristics of the heat retaining bottle of the present invention, the mouth part of the bottle body has a lead-out part mounted so that it can be attached to and detached from the mouth part, and a valve body that closes the inlet of the content liquid in the lead-out part. The inner plug attached so that it can be attached to and detached from the outer plug is locked to the outer plug, and the outer plug is made into a stable plugged state. If the cap is attached to the mouth of the bottle during regular holidays when the fitting is inadequate, the cap is pushed to the mounting position on the outer plug to put the outer plug into the plugged state, and the valve body is in the open position. In this case, the cap is returned to the closed position, and in both cases, the inner plug is pushed into the outer plug and the valve body is returned from the open position to the closed position by a single mounting of the cap. So, even if the cap is removed afterwards, the contents liquid will be inadvertent There is no possibility that Del Re.

It is sectional drawing which shows the heat retention bottle which concerns on embodiment of this invention. It is sectional drawing of the principal part seen changing the bottle direction of FIG. It is a disassembled perspective view which shows the stopper of the bottle of FIG. It is each sectional drawing which shows the open / close state of the stopper of the bottle of FIG.

  Hereinafter, the heat insulating bottle according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4 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.

  As shown in FIG. 1, the heat retaining bottle of the present embodiment has a metal bottle main body 1 having inner and outer walls made of stainless steel and a vacuum heat insulating space 2 therebetween, and a mouth portion 1 a of the bottle main body 1. A synthetic resin stopper 3 is attached so that the male screw 8 can be attached to and detached from the female screw 7 formed on the inner wall of the bottle body 1 from above, and the female screw 5 is arranged on the male screw 4 formed on the outer wall of the mouth 1a of the bottle body 1. And a cup 6 made of synthetic resin that covers the outer periphery of the stopper 3 so that it can be attached and detached by screwing from the outside, and the cap 6 is removed upward to open the stopper 3 to open the inner solution. The bottle body 1 and the stopper 3 can be washed out of the bottle body 1 by removing the stopper 3 upward from the bottle body 1. It can be. However, the specific heat insulating structure of the bottle body 1, the detachable structure of the stopper 3 and the cap 6, and the material of each member are not particularly limited in the present invention.

  As shown in FIGS. 1 and 2, the cap 6 has a handle 6 a for receiving the internal solution and making it easy to drink, and the handle 6 a is integrally formed on one side of the cap 6. As shown in FIGS. 1 and 2, the stopper 3 is attached to the mouth 1a of the bottle body 1 so as to be detachable from above by screwing the female screw 7 and the male screw 8, and has a bottomed shape to be plugged. A double plug structure is formed by the outer plug 11 and an inner plug 12 having a bottomed shape that is attached to the outer plug 11 so as to be detachable from above and is in a plugged state.

  The outer stopper 11 is attached to the bottle main body 1 to allow the content liquid to flow into the outlet chamber 13 to be poured out from the spout 13a shown in FIG. 1, and the outlet chamber 13 adjacent to the outlet chamber 13 is shown in FIG. It has the operation chamber 15 equipped with the valve body 14 which closes the inflow port 13b, and it is set as the plugging state as shown to FIG.1, FIG.2, FIG.4 (a) with respect to the said opening part 1a. The inner plug 12 is mounted so that it can be attached to and detached from the operation chamber 15 of the outer plug 11 from above, and the upper end portion of the operation chamber 15 is plugged as shown in FIGS. 1, 2, 4 (a) and 4 (b). And a lid 16 that closes the spout 13 a at the upper end of the outlet chamber 13. The inner plug 12 faces the operation chamber 15 from the outside of the inner plug 12 and the locking member 21 as shown in FIGS. 2, 3, and 4 that locks the inner plug 12 in the mounted state on the outer plug 11. 1, 3, 4 (a) and (b) for operating the valve body 14 and the lid 16, and the cap 6 and the inner plug 12 are the same as the inner plug 12. The contact-related portion as shown in FIG. 2 that is pushed directly or indirectly to the mounting position to the outer plug 11 by the mounting of the cap 6 when floating from the mounting position to the plug 11 and locked to the mounting position. P.

As a result, the mouth portion 1a of the bottle body 1 has an outlet plug 11 mounted so as to be detachable from above, and a valve body 14 that closes the inlet 13b of the content liquid in the outlet chamber 13. 1, 2, 4 (a) and 4 (b), the lid 16 closes the spout 13 a of the outlet chamber 13 with the inner plug 12 attached to the outer plug 11 so as to be detachable from above. The upper end of the operation chamber 15 adjacent to the lead-out chamber 13 is plugged as shown in FIG. 1 and FIG. 4 (b). However, as shown in FIG. Even when the stopper 12 is not properly attached to the outer stopper 11 and is floating as indicated by phantom lines in FIG. 2, when the cap 6 is attached to the mouth 1 a of the bottle body 1, The inner plug 12 is pushed to the mounting position on the outer plug 11 by the contact-related portion P as shown in FIG. Figure 1 an upper portion of the filled-in operation room 15 of the outer plug 11, FIG. 2, since the plugging state as shown in FIG. 4 (a), a double plugging condition is ensured. As a result, even if the cap 6 is subsequently removed, the content liquid does not leak inadvertently and can be used safely. Further, since the space between the inner and outer plugs 11 and 12 is divided into two spaces of the lead-out chamber 13 and the operation chamber 15, it is easy to suppress the retention of air, and the operation chamber 15 is kept in a plugged state by the inner plug 12. Although it is difficult for heat to escape upward, the outlet chamber 13 is opened as shown in FIG. 4 (b) each time the inner solution is poured out. Therefore, the heat retaining property can be enhanced together with the bottle body 1 having a heat insulating structure.

  In short, it is opened at the time of pouring out the content liquid, but it is relatively small and easily occupies a region other than the lead-out chamber 13 and the lead-out chamber 13 that can easily suppress deterioration of the heat insulation. Inside the operation chamber 15, the double-plug structure of the outer plugs 11, 12 closes the mouth 1 a of the bottle body 1 with good heat insulation to improve heat retention, and the outer plug of the inner plug 12 on the separation structure that can be washed in a round. 2, even if the cap 6 is incomplete, the outer plug 11 is plugged at the contact portion P with the cap 6 mounted as shown in FIG. Can be safely used without inadvertent leakage.

  Further, the valve body 14 and the lid 16 have a closing behavior by a spring 23 or the like that is applied to the valve body 14 as illustrated in FIGS. The cap 6 and the inner plug 12 are operated by opening the cap 6 when the cap 6 and the inner plug 12 are lifted from the mounting position on the outer plug 11 as shown in FIG. In addition to having a contact-related portion P as shown in FIG. 2 that is directly or indirectly pushed to the mounting position on the outer plug 11 and locked to the mounting position, the cap 6 and the lid 16 are When the lid 16 is in the open position shown in FIG. 4B, the cap 6 is attached to the position shown by the phantom line through the contact start position shown by the broken line in FIG. It is assumed that it has a contact relation part Q. As a result, the cap 6 is secured to the outer plug 11 by the attached cap 6, and even when the lid 16 of the inner plug 12 remains open, the cap 6 holds the cap in the open position. Is removed and closed together with the valve body 14, so that even if the cap 6 is subsequently removed, the internal solution is prevented from inadvertently leaking in connection with the function of holding the lid 16 together with the valve body 14 in the open position. Can be used more safely.

  The outlet chamber 13 has an inlet 13b at the bottom 13c, and the operation chamber 15 supports the valve element 14 at the bottom 15a. Specifically, the outlet chamber 13 has a pour spout 13a that opens to the upper end of the trunk portion, whereas the inlet 13b opens to the bottom 13c smaller than the inlet 13b. In addition, the operation chamber 15 has a cylindrical portion 15b that supports the valve rod 14a of the valve body 14 so that the valve rod 14a can be vertically moved by being inserted from below at the center of the bottom portion 15a, and on the cylindrical portion 15b of the valve rod 14a. The spring 23 is acted between the spring receiver 24 elastically engaged with the constricted portion 14c of the protruding portion and the bottom portion 15a of the operation chamber 15 to give the valve body 14 a closing behavior. As described above, the operation chamber 15 has a bottom so that the space is always sealed and heat insulation is improved. The outlet chamber 13 has an inflow port 13b, but has a bottom, thereby suppressing heat escape even if the operation chamber 15 is opened. Since it becomes easy, heat retention improves.

Further, as shown in FIGS. 1, 4A, and 4B, the locking member 21 is pivotally supported by the inner plug 12 by a shaft 21a, and the upper portion is connected to the outer plug 11 along the operation portion 21b. A lever having an engaging portion 21c that is elastically engaged with the stopper portion 29 and biased by a resin spring portion 26 as shown in FIGS. 1, 4 (a) and 4 (b) on the engagement side with the outer plug 11 The lever portion 27 includes the pivot portion supported by the shaft 21a as a whole, and the play S in the diameter line direction X as shown in FIG.
Is provided between the peripheral wall 41d and the inner guide wall 41e. In this way, the locking member 21 has a lever portion 27 pivotally supported by the inner plug 12 with the shaft 21a at the lower portion, an operating portion 21b at the upper portion, and an engaging portion 21c to the outer plug 11 in the middle. Thus, the engagement / disengagement stroke centered on the pivot portion of the operation portion 21b is more than the engagement / disengagement stroke centered on the pivot portion by the shaft 21a of the engagement portion 21c. And the lever ratio in the same direction but with a larger lever ratio, the lever portion can be operated with respect to the disengagement operation in the inner direction Y of the lever portion 27 as shown in FIGS. 2 to a position where the pivotal support portion by the shaft 21a of the lever portion 27 is free from play with the inner plug 12 by the urging force of the resin spring portion 26 acting in the direction of engagement with the outer plug 11 at 27. Pressed in a stable direction, and then operated As a result of the disengagement operation of the mast portion 21b in the Y direction, the lever portion 27 is smoothly rotated in the inner direction Y without turning around the pivotal support portion of the shaft 21a as a rough center, and the engagement portion 21c becomes the outer plug 11. 2 and FIG. 3, it can be surely removed from the locking portion 29, and the engagement can be released.

  As shown in FIGS. 2 and 3, the locking member 21 is attached to a locking portion 29 provided on the outer cylinder 31 fitted to the outside of the peripheral wall 11 b through a window 11 c provided on the peripheral wall 11 b of the outer plug 11. The inner plug 12 is engaged and locked to the mounting position on the outer plug 11. As a result, the locking member 21 extends from the inner plug 12 side through the peripheral wall 11b of the outer plug 11 to the locking portion 29 of the outer cylinder 31 on the outer side, and thus engages with the locking portion 29 of the engaging portion 21c. The engagement / disengagement stroke can be increased, so that a sufficient engagement function can be secured with a small engagement force, and the engagement / disengagement operation can be performed easily. Is easy to be aware of, and it is difficult to forget to operate or misoperate. Here, the outer cylinder 31 is attached to the outer periphery of the upper end of the peripheral wall 11b of the outer stopper 11 screwed to the inner wall of the mouth 1a of the bottle body 1 by forcible fitting 30, adhesion, ultrasonic welding, etc. It goes outside through the upper end of 1a and covers the mouth 1a. However, the outer cylinder 31 may be integrally formed on the peripheral wall 11b of the outer plug 11 or may be a part to be attached by screwing the outer plug 11 to the outer periphery of the mouth portion 1a.

  The outer plug 11 is attached to the mouth portion 1a by being screwed, so that the seal packing 32 attached to the lower end portion is pressure-bonded to the upward stepped portion 33 formed in the inner wall of the mouth portion 1a and the mouth portion 1a. The valve body 14 is pressed against the seal packing 32 from below to indirectly close the inlet 13b of the outlet chamber 13, but the inlet 13b may be closed directly. Good. However, the closed structure in which the valve body 14 is pressure-bonded to the seal packing 32 is to seal the entire region of the bottom portion 3a of the plug 3 that fits inside the mouth portion 1a, that is, the entire outlet chamber bottom portion 13c and the operation chamber bottom portion 15a. Thus, the inner solution does not leak unless the valve body 14 is opened. In addition, the base of the valve rod 14a is tightly sealed with the inner periphery of the cylinder portion 15b of the operation chamber bottom 15a through which the valve rod 14a is inserted, as shown in FIGS. A packing 34 is attached to cooperate with the valve body 14 to form a double seal structure. However, the seal by the seal packing 34 is located at the center of the bottom 3a of the stopper 3, and the content liquid is easily spread when the bottle main body 1 is tilted toward the front portion, that is, the eccentric side where the outlet chamber 13 is provided and poured out. It is considered by the range, and the anti-pour-out side where the inner solution does not reach does not require consideration of such a seal. Therefore, an outside air introduction port 35 is provided in a portion on the further anti-pouring side of the bottom portion 15a of the operation chamber 15 on the anti-pouring side, an outside air introducing port 36 provided on the anti-pouring side of the peripheral wall 11b of the outer plug 11, and Even if the lead-out chamber 13 is set to a size that is the upper limit of heat insulation by introducing outside air through the gap 37 as shown in FIG. 2 in the screw fitting portion between the outer plug 11 and the inner periphery of the mouth portion 1a. The liquid is poured out smoothly. Moreover, the outside air inlet 35 of the bottom portion 3a of the plug 3 is closed together with the inlet 13b of the outlet chamber 13 when the valve body 14 is closed, so that it causes heat release and leakage of the content liquid. Must not.

As shown in FIGS. 1, 2, 3, and 4 (a) and 4 (b), the inner plug 12 is forcibly fitted into a container-type main body 41 having an open upper end and the upper end opening of the main body 41. A hollow structure is formed by a lid portion 42 attached by a portion 40 or the like. As a result, the operation chamber 15 having a double plugging structure, combined with the hollow structure of the inner plug 12, forms a double sealed space above and below to further prevent the escape of heat, thereby further improving heat retention.

  Further, as shown in FIGS. 2 and 3, a pair of locking members 21 are provided at two locations on the diameter line X opposite to each other on the outer peripheral portion of the inner plug 12, so that the inner plug 12 is connected to the outer plug 11. By elastically engaging the two locking portions 29 on the diameter line of the outer plug 11 from the inside during mounting, the operation unit 21b locks the inner plug 12 at the mounting position to the outer plug 11 and the elastic engagement. An operation knob 43 that forms a knob for attaching and detaching the inner plug 12 and an operation knob 43 for removing the inner plug 12 are provided at opposite positions on the diameter line X with a non-slip ridge 43a. The operation knob 43 has an indirect contact portion P shown in FIG. 2 with the cap 6 in the inner plug 12. In this way, the locking member 21 is paired at two locations on the diameter line X opposite to the outer peripheral portion of the inner plug 12 and is elastically engaged with the outer plug 11 from the inside, whereby the inner plug 12 is connected to the outer plug 11. It can be stably locked to the mounting state. Moreover, the pair of locking members 21 have their respective operation knobs 43 positioned opposite to each other at two locations on the diameter line X of the inner plug 12 so that the thumb of one hand and the index finger or ring finger face each other. The operation of pulling inwardly in the Y direction to release the elastic engagement at the same time is performed at the same time, and the inner plug 12 is held and removed as it is and can be attached to the outer plug 11 on the contrary. Can be done. Further, the operation knob 43 forms an abutting relationship portion P that abuts against the cap 6 attached to the bottle body 1 when the inner stopper 12 is floating with respect to the outer stopper 11 and the inner stopper 12 is pushed to the attachment position. In addition, the inner plug 12 and the outer plug 11 are overhanging on the cap 6 side, leading to ease of operation.

  In addition, the protrusions as shown in FIGS. 2 and 3, in which the contact portion P of the operation knob 43 with the cap 6 is provided on both sides of the upper surface of the operation knob 43 parallel to the diameter line X direction. 43a. As described above, the operation knob portion 43 has the protrusion 43a on both sides parallel to the diameter line X direction forming the contact relation portion P with the cap 6, so that the protrusion 43a is the operation knob 43. It is useful as a finger guide indicating the operation position in the circumferential direction of the inner plug 12 on the surface of the operation knob portion 43. As shown in FIGS. 2 and 3, the operation knob portion 43 projects outward from the outer periphery of the inner plug 12, and a vertical operation knob wall 43 b faces the outer peripheral surface of the outer plug 11 at the projecting end. . The vertical operation knob wall 43b that protrudes from the outer periphery of the inner plug 12 of the operation knob portion 43 and faces the outer peripheral surface of the outer plug 11 is a counter surface for the engagement release operation and the pinching of the inner plug 12. After receiving from the finger for operating the disengagement operation and the pinching operation without slipping out or slipping without being obstructed by the outer plug 11 and the inner plug 12, and after responding to the disengagement position While maintaining the unlocked state, the inner plug 12 naturally shifts to the pinched state, and the unlocked inner plug 12 can be removed from the outer plug 11 without difficulty. Further, the detached inner plug 12 is attached to the outer plug 11 by holding the inner plug 12 with a pair of operation knob walls 43b at, for example, the disengagement operation position of the locking member 21, and the operation knob is maintained while maintaining this attachment state. By releasing the wall 43b, the locking member 21 returns to the engagement position, engages with the outer plug 11, and locks the inner plug 12 to the mounting position on the outer plug 11. Therefore, the outer plug 11 of the inner plug 12 is locked. Can be easily attached and detached.

The lid 16 is a lever member pivotally supported by a shaft 51 with respect to the inner plug 12 as shown in FIGS. 1 and 4B, and the tail end portion 16a located in the inner plug 12 is formed by the operation member 22 in FIG. 4 (a), the valve body 14 having the upward closing behavior is moved downward by being pushed down as shown in FIG. 4 (b) until it contacts the stopper 42a. It is assumed that the tail end portion 16a has a cam 52 that is opened and stabilized in the open position, and the operation member 22 is biased by a spring 53 so as to be returned to the upper position. The cam 52 opens the valve body 14 by pushing down the valve body 14 through the valve rod 14a by the opening operation of the lid 16 by the operating member 22, holds the valve body 14 in the open position at the end of the opening of the lid 16, and 16 and an opening holding portion 52b for stabilizing the opening 16 in the opening position. The opening holding portion 52b has an arc surface centered on the shaft 51, and the valve stem 14
The corner portion 52c between the opening operation portion 52a of the cam 52 and the opening holding portion 52b is closed by the valve rod 14a pressed against the cam 52 and the lid 16 is closed. When a neutral portion that does not rotate on any of the opening sides is formed and the pressure contact position of the valve stem 14a is disengaged from the corner portion 52c toward the opening operation portion 52a, the valve body 14 and the lid 16 are closed by the spring 23 of the valve body 14. When it is disengaged toward the open holding portion 52b, it is held in the open position by the spring 23 of the valve body 14. The spring 53 of the operation member 22 is for the operation member 22 to interlock with the closing operation of the lid 16. This is because play S1 is given between the operation member 22 and the lid 16 during the initial opening operation of the operation member 22 so that the opening operation can be performed smoothly, and even when the lid 16 is returned to the closed position. This is because the spring 53 compensates that the operating member 22 cannot return to the initial position. Accordingly, the spring force of the spring 53 is weak and does not affect the holding of the valve body 14 and the lid 16 in the open position by the spring 23 of the valve body 14.

  In this way, the lid 16 is operated by the operation member 22 and the valve body 14 is used by the lid 16 by lever operation centering on the pivotal portion by the shaft 51 of the lid 16 and the cam 52 of the lever tail end portion 16a of the lid 16. The optimal interlocking condition in the drive and driven relationship is satisfied, and the lid 16 and the valve body 14 can be opened and held in the open position by one operation of the operation member 22, as shown in FIG. When the lid 16 in the open position shown in FIG. 2 is pushed down slightly against the spring 23 of the valve body 14, the valve rod 14a moves from the opening holding portion 52b of the cam 52 over the corner portion 52c and the contact position is displaced toward the opening operation portion 52a. The lid 16 is closed together with the valve body 14 by the bias of the spring 23. Therefore, even if the lid 16 is forgotten to be tightened and the cap 6 is mounted, the lid 16 is pushed to the closing side by the cap 6 and is closed together with the valve body 14.

  Further, as shown in FIG. 2, the lever portion 27 of the locking member 21 is formed so that the engaging portion 21 c protrudes in a protruding piece shape, and when the inner plug 12 is fitted to the outer plug 11 from above, The downward slope 21d of the portion abuts against the upper edge of the locking portion 29 of the outer cylinder 31 of the outer plug 11 and moves over the upper edge of the locking portion 29 while retreating against the resin spring portion 26 with the lever portion 27, The lever 27 can be automatically engaged with the lower edge of the locking portion 29 by the return by the resin spring portion 26, and the inner plug 12 is pinched by the pair of operation portions 21b, that is, the pair of operation knob portions 43. Even if the locking member 21 is not operated to the disengagement position, it only has to be fitted while being pressed lightly from above, so that the inner plug 12 is engaged with the locking portion 29, for example. In the unlikely event that the joint 21c is placed, it will float from the outer plug 11 And even cap 6 is mounted in the state becomes as reliably engaged to the mounting position is effortlessly in the mounted state by the contact relationship with the cap 6.

  The lever portion 27 is located immediately above the engagement portion 21c so that the engagement release operation from the outer surface of the outer cylinder 31 by the operation knob portion 43 is realized with a compact structure while satisfying such a locking structure. The outer cylinder 31 is provided with a U-shaped operation knob 43 and is formed so as to reach the engaging portion 29 from the upper end of the outer cylinder 31 through a notch 62 as shown in FIGS. That is, it faces the outer peripheral surface of the outer plug 11, and the operation knob wall 43 b faces the outer peripheral surface of the outer plug 11 with little interference between the operation knob portion 43 and the inner plug 12. The upper piece 43d faces the upper surface of the inner plug 12. As a result, the operation knob portion 43 and the engaging portion 21c are S-shaped. Correspondingly, a stopper 71 for restricting the unlocking position of the operation knob portion 43 is formed on the upper surface of the inner plug 12, and the operation knob portion 43 is received by the stopper 71, and the inner plug is in the unlocked state. 12 will be pinched stably.

Further, the hollow portion of the inner plug 12 is provided with a bottom portion 41b which is further lowered by forming a step portion 41c with respect to the intermediate bottom portion 41a supporting the valve body 14, as shown in FIGS. 1, 4 (a) and 4 (b). The bottom portion 41b receives the spring 53 of the operation member 22, and the valve body 14 on which the spring 23 works and the operation member 22 on which the spring 53 works can be accommodated in a small space. The lid 16 is provided with a seal packing 61 as shown in FIGS. 1, 3, 4A and 4B so that the spout 13a can be closed tightly. As a result, the heat retaining property is enhanced, and even if the content liquid remains in the outlet chamber 13, it can be prevented from leaking.

  INDUSTRIAL APPLICABILITY The present invention can be practically used for a heat-retaining bottle and can be used without any incomplete assembly of a plug that can be disassembled to provide a plug with good heat insulation.
