Description

  The present invention relates to a liquid container including a main body provided with a heat insulating container and a lid for opening and closing a spout provided in the main body.

  This type of liquid container tends to condense on the outer surface of the lid when a liquid having a temperature lower than the outside air is stored in the heat insulating container. In order to prevent this dew condensation, a cylindrical portion with an upper end covering the spout is provided on the inner side of the lid, a plug body for closing the spout is attached to the inner side of the cylindrical portion, and the side peripheral wall of the cylindrical portion is further attached. Some have a space around them. Even if the cylinder portion is cooled, the periphery of the side peripheral wall is a space, so that the outer surface of the lid is hardly cooled by the heat insulating action, and condensation is prevented (see Patent Document 1).

  Further, in the above-mentioned Patent Document 1, a space is provided as much as possible between the plug body and the inner surface of the cylindrical portion, and further, the mounting shaft of the plug body protruding from the inner surface of the cylindrical portion is made hollow. Therefore, heat transfer between the plug body and the cylinder portion is prevented, and further condensation prevention is achieved.

Japanese Patent Laid-Open No. 2006-160278

  However, the liquid container of Patent Document 1 described above has room for improvement in that the cylindrical portion is formed on the lower surface of the outer shell member of the lid, and the upper portion of the cylindrical portion on the outer surface of the lid is more likely to condense than other portions.

  In the liquid container disclosed in Patent Literature 1, the opening / closing operation member for opening / closing the lid is spring-biased toward the front which is the lock side, and the lid is opened by pushing the opening / closing operation member against the biasing. Is unlocked. The opening / closing operation member is forcibly fitted to the inner periphery of the attachment hole formed on the main body side using a limited space within the shoulder width of the heat insulating container. For this reason, the opening / closing operation member is easily tilted due to wear, strong impact, or the like, and may be detached.

  Further, when the push-type opening / closing operation member as described above is employed, a lock holding mechanism is provided in order to prevent the lock from being unlocked unexpectedly. As this lock holding mechanism, a mechanism that restricts the backward movement of the opening / closing operation member in a state where the opening / closing operation member is in the locked position is widely adopted. When this type of lock holding mechanism is closed in a restricted state, a large load is applied to the opening / closing operation system from the lock holding mechanism to the opening / closing operation member, which is not preferable.

  In view of the above circumstances, the present invention provides a liquid container having a main body provided with a heat insulating container and a lid that opens and closes a spout provided in the main body, and a lid outer surface on a cylindrical portion on which a stopper is attached. Opening and closing when the lid is closed while the backward movement of the opening / closing operation member is restricted is made the first problem to make it difficult to condense on the second object and making the opening / closing operation member difficult to tilt. The third task is to reduce the burden on the operation system.

  The present invention for solving the first problem includes a main body provided with a heat insulating container, and a lid for opening and closing a spout provided in the main body, and an upper end closed cylinder covering the pour spout on the inside of the lid. In the liquid container in which a stopper is provided on the inner side of the cylindrical portion, and a space surrounding the side peripheral wall of the cylindrical portion is provided. The lower plate is provided with the cylindrical portion. And an outer cap that covers the lower plate from above, and a space is provided between the upper end closing portion of the cylindrical portion and the outer cap.

Specifically, if a lid having a lower plate provided with a cylindrical portion and an outer cap covering the lower plate is formed, a space can be formed between the outer cap and the cylindrical portion, and insulation can be achieved between them. become.
And if a space is provided between the upper end blocking part of the cylinder part and the outer cap, a heat insulating action can be obtained between the cylinder part and the lid outer surface on the cylinder part.
Therefore, according to the structure of this invention, even if a cylinder part is cooled with the stored liquid, it becomes difficult to condense on the cover outer surface on the cylinder part which attached the plug to the inner side.
Here, in the present invention, since the lid has the lower plate as described above, by using the lower plate, it is possible to effectively prevent the inclination while providing the opening / closing operation member on the lid side. It is.

  That is, the present invention for solving the second problem has an upper plate portion that covers the lower plate from above and both side plate portions that are connected to the upper plate portion, and is opened forward. The lower plate is a support plate portion extending from the cylindrical portion and extends between both side plate portions of the outer cap, and an opening / closing operation member for opening and closing the lid is provided with respect to the outer cap and the lower plate. The opening / closing operation member is vertically slid between the outer cap and the support plate portion of the lower plate, and the outer opening / closing operation member is interposed between the inner and outer double side walls provided on the opening / closing operation member. The side plate part on the same side of the cap is inserted and slidably guided.

Specifically, if the outer cap has an upper plate portion covering the lower plate from above and both side plate portions connected to the upper plate portion and is opened forward, the outer cap and the lower plate A space for sliding the opening / closing operation member for opening / closing the lid back and forth is obtained.
If the lower plate is a support plate portion extending from the cylindrical portion and extends between the both side plate portions of the outer cap, the both side plate portions of the outer cap are supported by the lower plate between them. The slide of the opening / closing operation member is stable.
Therefore, if the opening / closing operation member is combined with the outer cap and the lower plate so as to be slidable back and forth, and the opening / closing operation member is vertically sandwiched between the outer cap and the support plate portion of the lower plate, the opening / closing operation member When sliding, the play in the vertical direction is prevented.
Further, if the side plate portion on the same side of the outer cap is inserted between the inner and outer double side walls provided on the opening / closing operation member and is guided by sliding, a limited forward / backward stroke is provided when the opening / closing operation member slides. Even so, side play is reliably prevented.
Therefore, according to the structure of this invention, it becomes difficult to produce the inclination of an opening / closing operation member.

  Preferably, if a contact guide portion for preventing lateral play is provided between the lower plate and the opening / closing operation member, the sliding of the opening / closing operation member becomes more stable.

  Further, the present invention for solving the third problem is provided such that the opening / closing operation member is spring-biased forward toward the lock position side and is retracted from the lock position while the lid is closed. The main body is provided with a lock piece that can be horizontally slid between a lock holding position and a restriction release position for restricting the retraction of the opening and closing operation member in a state where the opening and closing operation member is in the locked position, When the lid is closed in a state where the lock piece is disengaged from the restriction release position, the opening / closing operation member is retracted and returned to the lock position. The lock piece is pushed by the taper cam portion of the opening / closing operation member and is slid to the restriction release position.

Specifically, if the opening / closing operation member is spring-biased toward the front which is the lock position side and provided so as to retract from the lock position while the lid is closed, the opening / closing operation member is After being retracted once from the lock position while being closed, it is returned to the lock position by spring bias.
If the main body is provided with a lock piece that is horizontally slidable between a lock holding position and a restriction release position that restrict the retraction of the open / close operation member in a state where the open / close operation member is in the lock position, the lock piece is horizontal. The slide holding the position is displaced between the lock holding position and the restriction release position.
If the lid is provided so as to be opened and closed by a hinge shaft provided at the rear end portion, the positional relationship between the lid and the main body while the lid is closed is determined.
For this reason, by providing the taper cam portion on the opening / closing operation member that determines the position when the lid is closed and closed by the spring bias, it becomes possible to move the lock piece that performs the slide displacement while maintaining the level.
When the lid is closed in a state where the lock piece is out of the restriction release position, the lock piece is brought into contact with the taper cam portion of the opening / closing operation member until the opening / closing operation member moves backward and returns to the lock position. If it is pushed and slides to the restriction release position, the lock piece is sent to the restriction release position by the taper cam when the cover is closed while the retracting of the opening / closing operation member is restricted. The burden on the system is reduced. Here, since the feeding operation is performed until the opening / closing operation member is retracted and returned to the lock position, the taper cam portion of the opening / closing operation member returned to the lock position with the lid closed is locked. The lock piece is displaced forward and backward, and the lock piece can be slid to the lock holding position.

As described above, the present invention that solves the first problem includes a main body provided with a heat insulating container and a lid that opens and closes a spout provided in the main body. It is possible to prevent condensation on the outer surface of the lid on the cylindrical portion.
The present invention for solving the second problem can make it difficult for the opening / closing operation member to be inclined.
The present invention that solves the above third problem can reduce the burden on the opening / closing operation system when the lid is closed while the backward movement of the opening / closing operation member is restricted.

Hereinafter, a liquid container according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the liquid container according to this embodiment includes a heat insulating container 11, a shoulder member 12 covering the upper end of the heat insulating container 11, a lid mounting base 13 attached to the shoulder member 12, and a shoulder member 12. A main body 10 provided with a handle 14, a bottom member 15 covering the lower end portion of the heat insulating container 11, and a spout 16 for communicating between the mouth of the heat insulating container 11 and the inner periphery of the lid mounting base 13. A lid 20 for opening and closing the spout 16 provided in the main body 10 is provided.

  The heat insulating container 11 is a vacuum double container having a structure in which a space between the inner container and the outer container is evacuated. The bottom member 15 is attached to the lower end of the outer periphery of the outer container of the heat insulating container 11.

  The inner peripheral portion of the shoulder member 12 covers the upper end portion of the mouth portion of the heat insulating container 11 via packing. This is in order to particularly protect the upper end portion of the mouth portion that is the joint portion between the inner container and the outer container.

  The lid mounting base 13 is screwed to the outer periphery of the shoulder member 12. The spout 16 is detachably fitted to the inner periphery of the lid mounting base 13 and the inner periphery of the mouth portion of the heat insulating container 11 via packing. When the spout 16 is fitted to the inner periphery of the lid mounting base 13, the upper end of the spout 16 protrudes from the lid mounting base 13.

As shown in FIGS. 3 and 4, the handle 14 has a substantially U shape straddling the shoulder member 12, and has a hinge shaft 12 a on the outer diameter of the shoulder member 12. Thereby, the handle 14 is rotatably attached to the shoulder member 12.
In this embodiment, the liquid container is a relatively large container having a capacity of at least 3 liters. For this reason, although the handle | steering-wheel 14 is employ | adopted as a hanging tool, when the capacity | capacitance of a liquid container is small, a belt can also be employ | adopted as a hanging tool.

  As shown in FIG. 1 and FIG. 3A, a shallowly inclined finger-hanging portion 15 a that is recessed upward is formed at the lower rear portion of the bottom member 15. This makes it easier to place a finger when the handle 10 is held and the main body 10 is tilted.

  Further, as shown in FIGS. 1 and 3B, a deeply inclined finger-hanging portion 15 b protruding forward is formed at the center of the front end of the bottom member 15. This makes it easier to place a finger when the handle 10 is held and the main body 10 is tilted.

  Here, the shallowly-fingered finger hanger 15a is provided because the deep-fingered finger hanger 15b on the front surface of the product cannot be protruded greatly. This is because, even when the amount of the remaining liquid is large and the container is heavy, it is possible to make it easy to hold the hand firmly.

  In addition, the deeply inclined finger-hanging portion 15b is provided so that the inclination angle of the liquid container becomes larger than when the finger-holding portion 15a for shallow inclination is put on, and the liquid can be poured into the spout without leaving the stored liquid. Because it can.

  Here, the rotation range of the handle 14 is limited by contact with the shoulder member 12.

  Specifically, as shown in FIG. 4, sliding contact surfaces 12 b and 14 a are respectively formed on the opposing surfaces of the handle 14 and the shoulder member 12, and the handle 14 is from the front side to the rear side or the rear side. When rotating from the side to the front side, the sliding contact surface 14a of the handle 14 comes into contact with the sliding contact surface 12b of the shoulder member 12, and a braking effect is obtained. In order to enhance the braking effect, the sliding contact surfaces 12b and 14a are tapered surfaces.

  Further, when the sliding contact surface 14a of the handle 14 reaches the terminal end of the sliding contact surface 12b of the shoulder member 12, the handle 14 abuts against the convex portion 12c and is prevented from rotating. In the detent position, the grip portion 14b of the handle 14 is set so as not to come into contact with the body portion of the heat insulating container 11, and the shocking contact between the two is reliably prevented. Container rubbing is prevented.

  As shown in FIGS. 1 and 5 to 9, the lid 20 is supported by a hinge mechanism so as to be rotatable with respect to the lid mounting base 13. The spout 16 is sealed in a closed state in which the lid mounting base 13 and the lid 20 are closed.

  More specifically, the lid 20 includes a lower plate 21 provided with a cylindrical portion 21a that closes the top end of the spout 16 and an outer cap 22 that covers the lower plate 21 from above. The opening / closing operation member 23 is configured to be slidable back and forth with respect to the outer cap 22 and the lower plate 21.

  The cylindrical portion 21a is inside the lid 20, and a plug 24 that closes the spout 16 is attached to the inside of the cylindrical portion 21a.

  The outer cap 22 has an upper plate portion 22a that covers the lower plate 21 from above, and both side plate portions 22b and 22b that are connected to the upper plate portion 22a, and is open forward and downward. The reason for opening downward is to facilitate the combination of the opening / closing operation member 23.

  The lower plate 21 is a support plate portion 21b extending from the cylindrical portion 21a and extends between the side plate portions 22b and 22b of the outer cap 22. Thereby, both the side plate parts 22b and 22b are supported by the lower board 21, and become difficult to fall down inside. The lower plate 21 is attached in a state of being sandwiched between both side plate portions 22b and 22b of the outer cap 22.

  A space 25 is provided between the upper end closing portion of the cylindrical portion 21 a and the outer cap 22. For this reason, it is difficult for condensation to occur on the outer surface of the outer cap 22.

  Furthermore, the space 25 is provided so as to surround the side peripheral wall of the cylindrical portion 21a, and the heat insulating performance between the cylindrical portion 21a, the outer cap 22, and the opening / closing operation member 23 is enhanced.

  From the viewpoint of preventing the above-mentioned dew condensation, it is better that there are more heat insulating portions between the plug body 24 and the outer cap 22. For this reason, also in this embodiment, a heat insulating portion is provided in the same manner as in Patent Document 1 described above.

  Briefly speaking, the plug body 24 is composed of a packing that is attached to and detached from a protruding shaft provided at the upper end closing portion of the cylindrical portion 21a and pressed against the opening edge of the spout 16 at the outer collar portion. The protruding shaft of the cylindrical portion 21 a is a hollow shaft that is open downward, and forms a heat insulating space together with the plug body 24. In addition, the groove | channel for releasing the pressure fluctuation | variation of heat insulation space is formed in the outer periphery of the protrusion shaft of the cylinder part 21a.

  Further, in the state where the outer flange portion of the plug body 24 is pressed against the opening edge of the spout 16, a heat insulating space is generated between the plug body 24 and the portion excluding the protruding shaft of the lower plate 21. .

  A hinge shaft insertion portion 22c is connected to the rear end of each side plate portion 22b of the outer cap 22, and the positional relationship with the main body 10 when the lid 20 is opened and closed is determined.

  The opening / closing operation member 23 has a front wall 23a, an upper wall 23b, and inner and outer double side walls 23c and 23d on both sides. This is because the sliding direction of the opening / closing operation member 23 is the front-rear direction.

The front wall 23 a of the opening / closing operation member 23 is formed so as to cover the front open space of the outer cap 22. Accordingly, the lid 20 is closed with the lid mounting base 13 so as to cover the spout 16.
A recess is formed on the outer surface side of the front wall 23a of the opening / closing operation member 23 so that the opening / closing operation member 23 can be easily pressed with a finger.

  The side plate portion 22b of the outer cap 22 located on the same side is inserted between the inner and outer double side walls 23c and 23d. By this insertion, the side walls 23c, 23d and the side plate portion 22b come into sliding contact or contact with each other, whereby the lateral displacement of the opening / closing operation member 23 is restricted.

  More specifically, a space between the side walls 23c and 23d of the opening / closing operation member 23 is an upper end closing space, and the upper end of the side plate portion 22b is in contact with the upper end closing portion, thereby opening / closing operation member 23. Is displaced upward.

  Further, a front and rear ridge 23e is formed on one of the side plates 22b on the same side as the side walls 23c and 23d of the opening / closing operation member 23, and a front and rear dent 22d is formed on the other. Due to the contact between the ridges 23e and the wall surfaces of the concave grooves 22d, the vertical direction and lateral displacement of the opening / closing operation member 23 are restricted, and the opening / closing operation member 23 is also restricted from being inclined relative to the horizontal. Therefore, by inserting the side plate portion 22b of the outer cap 22 located on the same side between the inner and outer double side walls 23c and 23d, the opening / closing operation member 23 is slid and guided in the front-rear direction.

  The front wall 23a of the opening / closing operation member 23 has an engagement wall 23f extending rearward on the inner surface side thereof. The engaging wall 23f is configured to engage front and rear with a flange portion 21c that extends forward from the center portion of the front end of the support plate portion 21b of the lower plate 21. By this engagement, the advance position of the opening / closing operation member 23 is determined. Further, the downward displacement of the opening / closing operation member 23 is restricted by the contact between the engagement wall 23f and the flange portion 21c.

  Further, inside the opening / closing operation member 23, there are provided receiving walls 23g that face both side portions of the front end of the support plate portion 21b of the lower plate 21. The upward displacement of the opening / closing operation member 23 is restricted by the contact between the receiving wall 23g and both sides of the front end of the support plate portion 21b.

  The front wall 23a of the opening / closing operation member 23 has a guide wall 23h extending rearward on the inner surface side thereof. The guide wall 23h is passed through a slit in the front-rear direction that divides the center portion of the front end of the support plate portion 21b and both side portions of the front end. By the contact between the guide wall 23 h and the slit edge 21 d of the lower plate 21, the lateral displacement of the opening / closing operation member 23 is restricted.

  The upper wall 23b of the opening / closing operation member 23 extends rearward from the front wall 23a, and is passed between the upper plate portion 22a forming the space 25 and the upper end closing portion of the cylindrical portion 21a. The upward displacement of the opening / closing operation member 23 is regulated by the upper wall 23b coming into contact with the upper plate portion 22a.

  Thus, when the upper wall 23b extending rearward from the front wall 23a is passed between the upper plate portion 22a and the tube portion 21a, the upward displacement slides not only on the front side of the opening / closing operation member 23 but also on the rear side. Regulated with length in direction. In this configuration, the opening / closing operation member 23 is particularly effective in preventing the upward displacement in view of the fact that each wall is connected to the front wall 23a so that the center of gravity is on the front side and the rear side is easily displaced upward by a moment load. This is preferable in that it can be performed.

  Here, the opening / closing operation member 23 is normally set to have a gap so as not to come into contact with the upper end closing portion of the cylindrical portion 21a. This is to prevent heat conduction from occurring between the cylinder portion 21a and the upper plate portion 22a via the upper wall 23b.

  Further, the upper wall 23b and the upper plate portion 22a are in partial contact with each other. This is because if partial contact is made, even if heat transfer occurs between the tube portion 21a and the upper plate portion 22a via the upper wall 23b, this can be reduced.

In this embodiment, only one long ridge 22e is formed on the upper portion of the cylindrical portion 21a on the inner surface of the upper plate portion 22a, and the upper wall 23b is usually formed only by this ridge 22e. Set to contact with. Thereby, said heat transfer can be prevented as much as possible while preventing the upward displacement of the opening / closing operation member 23.
What is necessary is just to set the length of the protrusion part 22e so that a contact with the upper wall 23b may not remove | deviate in the sliding range of the opening / closing operation member 23. FIG.
In addition, the protrusion part 22e is set in the position which contacts the center of the width | variety of the upper wall 23b, and it is prevented that the opening / closing operation member 23 contacts the protrusion part 22e and inclines.

The opening / closing operation member 23 by contact between the upper wall 23b and the upper plate portion 22a, contact between the upper end closing portion between the side walls 23c and 23d and the side plate portion 22b, and contact between the receiving wall 23g and the support plate portion 21b. Due to the upward displacement restriction, the downward displacement restriction of the opening / closing operation member 23 due to the contact between the engagement wall 23f and the flange portion 21c, and the vertical displacement restriction due to the contact between the convex portion 23e and the wall surface of the concave groove 22d, Since the opening / closing operation member 23 is firmly positioned in the vertical direction, and the forward movement is restricted by the engagement of the engagement wall 23f and the flange portion 21c, that is, the opening / closing operation member 23 is prevented from coming off, the opening / closing operation member 23 is 21 and the outer cap 22.
Further, since the lateral displacement regulation of the opening / closing operation member 23 by the contact between each side wall 23c, 23d and the side plate portion 22b and the contact between the guide wall 23h and the slit edge 21d of the lower plate 21 is obtained, the sliding operation is limited. Even when the front / rear stroke is long, the lateral displacement of the opening / closing operation member 23 is reliably prevented. Therefore, according to this embodiment, it is possible to prevent the opening / closing operation member 23 from being inclined.

  A long hole 23i is formed in the upper wall 23b of the opening / closing operation member 23, and a spring receiver 22f formed in the upper plate portion 22a of the outer cap 22 is passed through the long hole 23i. A spring 26 is incorporated in a compressed state between the spring receiver 22 f and a spring receiver 23 j provided inside the opening / closing operation member 23. The spring 26 urges the opening / closing operation member 23 to move forward.

Moreover, the opening / closing operation member 23 has a hanging wall 23k on the inner side that engages and disengages with the hook portion 13a of the main body 10. In a state where the opening / closing operation member 23 is restricted to the forward movement position by the engagement wall 23f and the flange portion 21c, the hook wall 13k is vertically engaged with the hook portion 13a and the lid 20 is closed. That is, the advance position of the opening / closing operation member 23 is a lock position.
The opening / closing operation member 23 can be pushed in until the engagement wall 23f and the like come into contact with the cylindrical portion 21a. At this time, the hanging wall 23k is separated from the hook portion 13a. When the opening / closing operation member 23 is not pushed in, the opening / closing operation member 23 naturally returns to the locked position by the bias of the spring 26.

  A combination of the opening / closing operation member 23 will be described. First, with the lower surface of the outer cap 22 facing upward, the upper wall 23b of the opening / closing operation member 23 is fitted inside the outer cap 22, and the spring receiver 22f of the upper plate portion 22a is passed through the elongated hole 23i of the upper wall 23b. The spring 26 is attached to the spring receiver 23j of the opening / closing operation member 23.

Next, when the lower plate 21 is pushed into the inner surface of the outer cap 22, the lower plate 21 has a side end locking wall 22 g and a rear end locking wall 22 h protruding from the upper plate portion 22 a and the side plate portions 22 b. After getting over, the locking walls 22g, 22h and the supporting wall surface 22i are locked to the outer cap 22, and the mounting of the lower plate 21 is completed. Thereby, the space 25 is formed.
When the lower plate 21 is attached, the opening / closing operation member 23 is set at a position where the engagement wall 23f and the receiving wall 23g do not interfere with the support plate portion 21b of the lower plate 21 using the length of the long hole 23i. The

  Next, when the opening / closing operation member 23 is pushed in, the guide wall 23h of the opening / closing operation member 23 is inserted into the slit of the lower plate 21, and the engagement wall 23f of the opening / closing operation member 23 gets over the flange 21c of the lower plate 21 to open / close. The receiving wall 23g of the operation member 23 faces both sides of the front end of the support plate portion 21b of the lower plate 21, and the combination of the lower plate 21, the outer cap 22, and the opening / closing operation member 23 is completed. In order to prevent the lower plate 21 from being detached from the rear end locking wall 22h at the time of pushing, these are engaged not only in the front-rear direction but also in the downward direction.

  As described above, since each displacement is restricted only by each wall along the sliding direction of the opening / closing operation member 23, the lower plate 21 is first attached to the outer cap 22 and the opening / closing operation member 23 is moved. After the slide space is formed, the opening / closing operation member 23 can be simply assembled by simply pushing it in.

  The hinge mechanism that opens and closes the lid 20 around the lid hinge shaft 27 incorporates an urging spring so that the lid 20 opens and rotates. When the hanging wall 23k of the opening / closing operation member 23 is disengaged from the hook portion 13a of the lid mounting base 13, the lid 20 finishes opening naturally due to the spring bias of the hinge mechanism.

  Here, as for the upper board part 22a of the outer cap 22, the rear-end intermediate part is recessed. The recessed portion is fitted into a convex portion formed on the lid mounting base when the lid 20 is opened. When the lid mounting base 13 is screwed or unscrewed by grasping the opened lid 20, a part of the torque is dispersed by the engagement between the recessed portion and the protruding portion, and a load acting on the hinge mechanism is reduced. It is reduced.

  When the lid 20 is closed and rotated, the opening / closing operation member 23 is retracted by the sliding wall 23k sliding on the taper cam surface formed at the upper end of the hook portion 13a, and after passing through the taper cam surface of the hook portion 13a, the opening / closing operation member 23 is advanced to the lock position, the hanging wall 23k is engaged with the hook portion 13a, and the lid 20 is kept closed. By closing and rotating the lid 20, the plug 24 is pressed against the opening edge of the spout 16, and the cylindrical portion 21 a of the lower plate 21 covers the upper end of the spout 16.

  Here, as shown in FIGS. 6, 7, 9, and 10, the main body 10 has a lock holding position that regulates the backward movement of the opening / closing operation member 23 in a state where the opening / closing operation member 23 is in the locked position. A lock piece 28 that is horizontally slid between the restriction release position is provided.

  The lock piece 28 protrudes from a window 13 b formed at the upper end portion of the main body 10, and is horizontally supported by a pressing plate 29 attached to the inner surface side of the main body 10. A slide space of the lock piece 28 is formed by the inner surface of the main body 10 and the pressing plate 29, and the horizontal slide of the lock piece 28 is guided by the inner surface of this space.

  The lock piece 28 has an operation knob 28a protruding from an operation window 13c formed on the front surface of the main body 10, and can be moved between a lock holding position and a restriction release position. .

  The lock piece 28 is opposed to the front and rear of the abutting wall 23l provided inside the opening / closing operation member 23 in the lock holding position, and prevents the opening / closing operation member 23 from retreating. One side portion of the lower end of the abutting wall 23l is notched and formed so as not to face the lock piece 28 and the front and rear. The region where the lock piece 28 is in front of and behind the notch space of the abutting wall 23l is the restriction release position.

  The window 13b is in front of the hook portion 13a, and the lock piece 28 and the contact wall 23l are located in front of the contact wall 23l in a state where the opening / closing operation member 23 is in the lock position, and the horizontal slide Is set to a possible relationship.

  When the lid 20 is closed in a state where the lock piece 28 is out of the restriction release position, the other side portion of the lower end of the abutting wall 23l moves the lock piece 28 until the opening / closing operation member 23 moves backward and returns to the lock position. A taper cam portion is slid to the restriction release position.

  More specifically, as shown in FIGS. 10A and 10B, when the lid 20 is closed in a state where the lock piece 28 is out of the restriction release position, that is, in the lock holding position, the opening / closing operation member The hanging wall 23k of 23 comes into contact with the taper cam surface of the hook portion 13a and retracts. As a result, the abutting wall 23l also retracts in the same manner and contacts the upper end of the lock piece 28.

  As shown in FIGS. 10C and 10D, the lock piece 28 is pushed by the taper cam portion of the abutment wall 23l and slid to the restriction release position until the hanging wall 23k comes off the taper cam surface of the hook portion 13a. . At this time, the lock piece 28 is pressed by the abutment wall 23l, but is supported horizontally by the press plate 29 and can slide without trouble. Therefore, the load on the opening / closing operation system including the lid 20 including the opening / closing operation member 23, the lock piece 28, the pressing plate 29, and the inner surface of the main body 10 is reduced.

  When the opening / closing operation member 23 advances to the lock position, the abutting wall 231 advances in the same manner. Therefore, as shown in FIG. 7, the lock piece 28 and the abutting wall 231 can horizontally slide the lock piece 28. Returning to the positional relationship, the lock piece 28 can be slid to the lock holding position without hindrance.

  As the configuration of the lid, the lock piece, etc., an appropriate configuration can be adopted as long as the operation and effect of the present invention can be obtained. For example, a configuration in which a shoulder member and a lid mounting base are integrally provided, a configuration in which a plug body can be screwed to the inner periphery of the lid mounting base, and the like can be adopted as in Patent Document 1 described above. Moreover, as a heat insulation container, the heat insulation container which has other heat insulation structures, such as what interposed the heat insulating material between the inner container and the outer container, can also be utilized.
