The first body portion 20 and the second body portion 20 are provided with a plate portion 19, The lower lid 4 is inserted into the gap B between the second body portion 20 and the second outer circumferential plate portion 19 formed by the lower body portion 20 so as to be able to flow from the upper side. The second body portion 20 having the upper portion joined to the lower surface of the top plate portion 18 is provided with a heat insulating material 21 inside and has a high heat retaining performance. The airbag 13 is provided at a position facing the air hole 13 at the center of the lower portion thereof with an air hole closure A packing holding portion 24 for detachably holding the packing 23 is provided.

The engaging groove 22 is formed in a substantially L-shape in a substantially L-shape with its long side in the vertical direction and its long side. The insertion groove 25 A vertical guide path 26 extending in the up-and-down direction continuing to the inserting portion 25, a slant guide path 27 inclined continuously in an upward slanting manner to the vertical guide path 26, A horizontal guide path 28 continuous to the guide rail 27 and a first inclined guide 29 inclined downwardly in an inclined downward direction are provided integrally on the upper portion of the horizontal guide path 28. [ The first inclined guide portion 29 is provided with a closed state storage portion 31 having a first contact portion 30 which serves as the other end of the engagement groove 22. The closed state storage portion 31, And a second inclined guide portion 33 inclined downward toward the one end side is continuously provided. An open state storage portion 34 continuous with the second inclined guide portion 33 is provided at a lower position of the horizontal guide path 28 and the first inclined guide portion 29, (34) is formed with a second contact portion (35) formed by a difference in height from the inclined guide path (27).

The air hole closure packing 23 for closing the air hole 13 is made of an elastic member made of rubber or elastomer and is formed in a circular shape in plan view and is inserted into the packing holding portion 24 Shaped resiliently-resilient gap-holding portion 37 and a resilient closure portion 38 protruding downward toward the air hole 13 in a hemispherical shape, And the elastic dent gap-holding portion 37 is formed with a vent hole 39 communicating with the inside and outside.

Next, the operation of the opening and closing mechanism of the lid-equipped container 1 having the above-described configuration will be described. First, when the lid-attachable container 1 is assembled, the container body 2 is slidably inserted into the gap A between the first body 10 and the first outer circumferential plate 11 of the lower lid 4, The lower lid 4 is mounted on the container body 2 by screwing the lower lid 4 and the lower lid 4 into the male screw 9 of the container body 2 and tightly tightening the same, The elastic packing 14 attached to the attachment groove 15 of the lower lid 4 is brought into contact with the exponent portion 8 formed on the inner cylinder 7 of the lower lid 4 as shown in Fig. The upper lid 5 covering the upper opening 3 of the lower lid 4 is inserted into the engaging groove 22 provided at the position of the engaging projections 16 arranged at three places with equal intervals, The engaging projections 16 of the lower lid 4 are inserted into the vertical guide passage 26 and the inclination guide 16 by inserting the engaging projections 16 from the inserting portions 25 at the same time, (27). The engaging projection 16 guided by the inclined guide path 27 is pivoted toward the closed direction which is the other end side of the engaging groove 22 while pressing the upper lid 5 downward, The first guiding path 28 and the first inclined guiding portion 29 are guided in this order along the upper portion of the upper lid 28. When the first guiding portion 28 is brought into contact with the first contacting portion 30 in the finally closed storage portion 31, The upper lid 5 and the lower lid 4 are engaged with each other so that the assembled state of the lid attaching container 1, that is, the state where the container lid 2, the outer lid and the lower lid 4 are integrated, is closed. On the other hand, when the engaging projection 16 is guided from the one end side to the other end side of the closed state storage portion 31, the protruding portion 32 capable of obtaining a click feeling is ridden, and then the first contact portion 30 It can be confirmed that the engaging projection 16 enters the closed state storage portion 31 and is in the closed state. When the engaging projection 16 is brought into contact with the first contact portion 30, the rotation of the upper lid 5 in the closed direction is suppressed and the lower lid 4, which is integrated with the upper lid 5, When the lower lid 4 is not attached to the container body 2, the upper lid 5 and the lower lid 4 are screwed together with the container body 2 in a state in which they are integral with each other, Can be performed. Since the plurality of engaging projections 16 and the engaging grooves 22 are formed in the circumferential direction, the upper lid 5 and the lower lid 4 are easily held horizontally, The operation can be easily performed.

The air hole closure packing 23 before elastic deformation retains the elastic closure part 38 and the air hole 13 in a state of having a constant clearance C by the elastic denture holding part 37. [ The height T1 of the elastic dent gap holding portion 37 is set to a height T2 from the insertion portion 25 to the lower portion of the inner inclined guide portion 40 in the inclined guide path 27, (T1? T2), and their height is lower than the height T3 from the insertion portion 25 to the closed state storage portion 31 (T1? T2 <T3). With the above-described structure, until the engaging projection 16 is inserted into the engaging groove 22 and the upper portion of the vertical guide passage 26, in which the rotation of the upper lid 5 is transferred, The rotation of the upper lid 5 in the closing direction is stopped when the engaging projection 16 is moved to the upper portion of the inclined guide path 27 so that the upper lid 5 The elastic dent clearance holding portion 37 is elastically deformed and the air hole 13 is closed by the elastic occlusion portion 38. As a result, The gap D between the upper inner circumferential surface of the container body 2 and the first body 10 of the lower lid 4 expands as the exponent portion 8 and the elastic packing 14 come into contact with each other and the lower lid 4 The air hole 13 of the container main body 2 is closed by the contact with the elastic occlusion portion 38 so that liquid tightness due to the contents in the container main body 2 can be ensured without leaking liquid to the outside. The air hole closure packing 23 is elastically deformed while the engaging projection 16 is housed in the closed state storage portion 31 which is not less than the height of the vertical guide path 26. Therefore, The upper lid 5 is always urged upward so that the engaging projection 16 is held in contact with the lower portion of the closed state storage portion 31. [

On the other hand, when disassembling the lid-attachable container 1, the upper lid 5 is rotated in the open direction of the one end side of the engagement groove 22. When the upper lid 5 is rotated toward the open direction, the engaging projection 16 is in a state in which the upper lid 5 is always urged upward by the restoring force of the air hole closure packing 23, The protruding portion 32, the second inclined guide portion 33 and the opened state storage portion 34 are guided in this order from the storage portion 31 to the opened state storage portion 34 in order of the opened state storage portion 34). At this time, the lower portion of the opened state storage portion 34 has a height T4 (T4 &lt; T4) slightly lower than the height T2 from the insertion portion 25 to the lower portion of the inner inclination guide portion 40 in the inclined guide path 27, The air hole closure packing 23 having the elastic closure part 38 that has closed the air hole 13 is restored by the elastic restoring force and the elastic closure part 38 is removed from the air hole 13 The ventilation hole 39 is closed by the air hole 13, so that the container body 2 is released from the reduced pressure state. Therefore, since the elastic closure part 38 of the air hole closure packing 23 is moved away from the air hole 13 and only the engagement protrusion 16 enters the opened state storage part 34, The decompression can be easily released even in the decompressed state, so that the detachment can be easily performed. In addition, when the engaging projection 16 is located in the opened state storage portion 34, the height T1 of the elastic securing clearance holding portion 37 is increased from the insertion portion 25 to the upper portion of the inner inclined guide portion 40 In the opened state storage portion 34, the engaging projection 16 is not guided to the inclined guide path 27, so that the restored elastic spacing gap holding portion 37 is not guided to the inclined guide path 27, It is possible to stably maintain the engagement state of the upper lid 5 and the lower lid 4 with each other. On the other hand, when the engaging projection 16 is guided from the other end side to the other end side of the closed state storage portion 31, the protrusion portion 32 capable of obtaining a click feeling is ridden and then guided to the opened state storage portion 34 It is possible to easily confirm before and after the decompression cancellation.

When the upper lid 5 is further pivoted in the open direction from the state where the engaging projection 16 is located in the open state storage portion 34, the engaging projection 16 is engaged with the open state storage portion 34 And is brought into contact with the second contact portion 35 provided at one end. The upper lid 5 is rotated only in the open direction so that the engagement protrusions 16 are prevented from moving in the inclined guide paths 27 by the height difference from the lower portion of the open state storage portion 34 to the upper portion of the inner inclined portion And is not peeled off from the lower lid 4. [0064] Therefore, when the engaging projection 16 is rotated in the open direction while being in contact with the second contact portion 35, the screw of the lower lid 4 is loosened so that the upper lid 5 and the lower lid 4 The upper lid 5 and the lower lid 4 do not have to be peeled apart from each other since the lid can be separated from the container body 2 in an integrated state and the stopper can be opened. It can be removed without touching.

In order to guide the engaging projection 16 from the open state storage portion 34 to the inclined guide path 27 and detach the upper lid 5 from the lower lid 4, as shown in Fig. 7, In the step of moving from the closed state storage portion 31 to the opened state storage portion 34 while the upper lid 5 rides over the projected portion 32, the upper lid 5 is pivoted in the open direction while pressing the upper lid 5 downward. As a result, the air hole closure packing 23 is elastically deformed and the upper lid 5 is lowered, so that the engaging projection 16 in the opened state storage portion 34 can be guided to the inclined guide path 27. The engaging projection 16 guided by the inclined guide path 27 guides the inclined guide path 27 downward when the upper lid 5 is rotated in the open direction so that the air hole occluding packing 27 The elastic dart gap holding portion 37 of the upper lid 5 is gradually restored by the resilient restoring force so that the pivotal movement of the upper lid 5 from the lower lid 4 is assisted It can be easily removed. With this configuration, in order to remove the upper lid 5 from the lower lid 4, it is necessary to press the upper lid 5 in the vertical direction in addition to the pivotal movement in the lateral direction, so that the upper lid 5 is rotated in the open direction for some reason It is not easily peeled off from the lower lid 4 and liquid leakage can be prevented. Further, by disassembling the lower lid 4 and the upper lid 5, sanitary handling can be performed since each of them can be washed to a fine detail.

As described above, in this embodiment, the container main body 2 having the opening portion, the lower lid 4 screwed on the container main body 2, and the upper lid 5 fitted to the lower lid 4, The lower lid 4 has an air hole 13 communicating with the inside and outside formed at the central portion and an elastic packing 14 brought into contact with the inner surface of the container body 2 provided at the lower portion The upper lid 5 has an air hole closure packing 23 having an elastic closure part 38 at a position facing the air hole 13 and the inner lid 4 or the upper lid 5, And an open state storage part 34 for holding the engagement protrusion 16 and maintaining the open state of the upper lid 5 is formed on the other side of the outer lid 5, And an engagement groove 22 having a closed state storage portion 31 that maintains the closed state is formed The cap can be opened while the upper lid 5 and the lower lid 4 are integrated.

When the engaging projection 16 is located in the open state storage portion 34 of the engaging groove 22, the air hole 13 is not blocked by the elastic occlusion portion 38, When the engaging projection 16 is located in the closed state storage portion 31 of the upper lid 5 and the lower lid 4 by closing the air hole 13 by the elastic occlusion portion 38, The decompression can be released.

The engaging groove 22 has an insertion portion 25 communicating with the opened state storage portion 34 and the closed state storage portion 31 so that the integrated upper and lower lids 5 and 4 ) Can be disassembled, and the details of each lid can be washed.

The protruding portion 32 is formed between the open state storage portion 34 and the closed state storage portion 31 that are communicated with each other to thereby engage the open state storage portion 34 and the closed state storage portion 31 It is possible to obtain a click feeling when the projection 16 moves and to clearly identify the position of the engaging projection 16 and to easily confirm whether or not the container body 2 is decompression released.

The upper lid 5 or the lower lid 4 has an elastic dent gap holding portion 37 having a height higher than that of the elastic occlusion portion 38 so that the open state storage portion 34 of the engagement groove 22 The engaging position of the upper lid 5 and the lower lid 4 is maintained so that the lid can be stabilized.
