A safety member 12 that can be moved up and down by a change in the internal pressure of the container body 1 and the moving members 9 and 9 and that can prevent the movement of the moving member 9 at the raised position of the safety member 12. Since the safety mechanism 11 including the stop portion 13 is provided, the safety member 12 passes through the large-diameter portion 13a at the fixed position K where the pair of locking members 3 and 3 are located inside as shown in FIGS. The safety member 12 rises due to an increase in the pressure in the container body 1. On the other hand, as shown in the imaginary line position in FIG. Here, when the operation member 14 is reciprocally swung to move the moving member 9 outward from the fixed position K to the release position F in a state where the pressure in the container body 1 is still high, FIG. 7, the peripheral surface of the safety member 12 in the raised position The edge part of the small groove part 13b contacts, and thereby, the outward movement of the moving member 9 is blocked, and the outward movement of the moving member 9 is blocked by the locking part 13, thereby preventing the unexpected lid 2 from being removed. Since the steam vent valve 16 having an adjustment weight 16b for adjusting the pressure in the container main body 1 is provided in the lid 2, the pressure in the container main body 1 is adjusted. Can increase safety.
この場合、上記運動変換機構１５として、ハンドル６に歯車横軸１５ａを回転自在に横設し、歯車横軸１５ａに操作部材１４の基部を固定し、歯車横軸１５ａと上記歯車軸５との間に歯車列１５ｂ・１５ｃを介装し、操作部材１４の基部を固定した歯車横軸１５ａの軸線を中心とする操作部材１４の往復揺動動作により歯車横軸１５ａを正逆回転させ、歯車列１５ｂ・１５ｃを介して歯車軸５を正逆回転させるように設けているから、操作部材１４の往復揺動動作により歯車横軸１５ａが正逆回転して歯車列１５ｂ・１５ｃを介して歯車軸５が正逆回転し、蓋体２の固定釈放を容易に行うことができると共に操作機構４の構造を簡素化することができ、又、この場合、上記安全部材１２内に閉蓋状態における容器本体１内の過大な圧力上昇時に開口して蒸気を逃がす開閉弁１２ａを設けてなるから、上記蒸気抜き弁１６の圧力調節作用に加えて過大な圧力上昇時に開閉弁１２ａが開口して蒸気を逃がすことにより一層安全性を高めることができる。 In this case, as the motion conversion mechanism 15, a gear horizontal shaft 15 a is rotatably disposed on the handle 6, the base of the operation member 14 is fixed to the gear horizontal shaft 15 a, and the gear horizontal shaft 15 a and the gear shaft 5 are The gear horizontal shaft 15a is rotated forward and backward by the reciprocating swinging motion of the operation member 14 about the axis of the gear horizontal shaft 15a with the gear trains 15b and 15c interposed therebetween and the base of the operation member 14 fixed. Since the gear shaft 5 is provided to rotate in the forward and reverse directions via the rows 15b and 15c, the gear horizontal shaft 15a is rotated in the forward and reverse directions by the reciprocating swinging motion of the operating member 14, and the gears are transmitted via the gear rows 15b and 15c. The shaft 5 rotates forward and backward, the lid body 2 can be fixed and released easily, and the structure of the operation mechanism 4 can be simplified. In this case, the safety member 12 is in a closed state. When excessive pressure rises in the container body 1 Since the opening / closing valve 12a for opening and releasing the steam is provided, in addition to the pressure adjusting action of the steam release valve 16, the opening / closing valve 12a opens when the pressure rises excessively, thereby further improving the safety. Can do.
尚、本発明は上記実施の形態例に限られるものではなく、例えば、上記運動変換機構１５として、上記操作部材１４は１８０度の範囲の往復揺動動作により歯車軸５を正逆回転させ、一対の移動部材９・９を蓋体２の半径方向に相互に異方向に移動させる構造としているが、上記操作部材１４を１８０度以外の範囲、例えば、９０度の範囲の往復揺動動作により歯車軸５を正逆回転させる構造とすることもでき、又、運動変換機構１５として、歯車構造以外のリンク構造等を採用することもでき、更に、容器本体１、蓋体２、係止部材３・３、操作機構４、歯車軸５、ハンドル６、操作部材１４等の構造や形態等は適宜変更されるものである。 The present invention is not limited to the above-described embodiment. For example, as the motion conversion mechanism 15, the operation member 14 rotates the gear shaft 5 forward and backward by a reciprocating swinging operation in a range of 180 degrees. The pair of moving members 9 and 9 are configured to move in different directions in the radial direction of the lid body 2, but the operation member 14 is moved by a reciprocating swinging operation in a range other than 180 degrees, for example, 90 degrees. The gear shaft 5 can be configured to rotate forward and reverse, and a link structure other than the gear structure can be employed as the motion conversion mechanism 15, and the container body 1, the lid body 2, and the locking member. 3 and 3, the structure and form of the operation mechanism 4, the gear shaft 5, the handle 6, and the operation member 14 are appropriately changed.
以上、所期の目的を充分達成することができる。 As described above, the intended purpose can be sufficiently achieved.
