Examples of the present invention will be described below. As shown in FIGS. 1 and 2, the container 1 includes a main body member 2, a lid member 4, and a rotation lock member 6 pivotally supported by the lid member 4. The main body member 2 has horizontally extending cylindrical protrusions 8 at two opposing locations on its outer side wall.

所望によりクリツク凹部42が設けられる。 A shaft hole 16 of the rotation lock member 6 is fitted into the protrusion shaft 14, and a protrusion 8 is fitted into the rotation lock member 6.
A cam groove 20 is provided in which the cam groove 20 is engaged. The cam groove 20 consists of a continuous outer cam part 34 and a continuous inner cam part 40. The continuous outer cam portion 34 engages the protrusion 8 when the rotation locking member 6 is in the locked position shown in FIG.
and the escape cam surface portion 30 separated by a distance D from the
and a convex cam surface portion 32 that abuts the protrusion 8 and separates the protrusion shaft 14 and the protrusion 8 to open the lid member 4 when in the unlocked position shown in FIG. When the rotation locking member 6 is in the locking position, the continuous inner cam portion 40 contacts the protruding portion 8 and brings the protruding shaft 14 and the protruding portion 8 closer together to create a seal between the main body member 2 and the lid member 4. It consists of a convex cam surface part 36 that forms a relationship, and an escape cam surface part 38 that does not come into contact with the protrusion 8 when in the unlocked position. The convex cam surface portion 36 has
A click recess 42 is provided if desired.
以上の構成において、本体部材2に蓋部材4を

ツク力によつて阻止される。 In the above configuration, when the lid member 4 is engaged with the main body member 2 and the rotation lock member 6 is rotated to the locking position shown in FIG.
The convex cam surface portion 36 of 0 comes into contact, the protruding shaft 14 and the protruding portion 8 are brought closer together, and a sealing relationship is established between the main body member 2 and the lid member 4. Here, if the click concave portion 42 is provided in the convex cam surface portion 36,
The protrusion 8 falls into the click part 42, and the rotation of the rotary lock member 6 in the locking position is prevented by a certain amount of click force.

によつて比較的小さな力によつて突出軸14と突
出部8とを引離して蓋部材4を本体部材2から持
上げることができる。 Next, when the rotation lock member 6 is rotated against the friction force or click force between the protrusion 8 and the convex cam surface 36 to the unlocked position shown in FIG. The convex cam surface portion 3 comes into contact with the protruding shaft 14 and the protruding portion 8 to separate them. At this time, for example, even if negative pressure is generated in the container 1 due to cooling of the food,
Due to the lever action and wedge action of the rotating lock member 6, the projecting shaft 14 and the projecting portion 8 can be separated with a relatively small force, and the lid member 4 can be lifted from the main body member 2.
ところで、2つの回転ロツク部材6が錠止位置

損することはない。 By the way, when only one rotary lock member 6 is rotated from the state in which the two rotary lock members 6 are in the locked position to the unlocked position, the lid member 4 moves the other rotary lock member 6 to the protrusion 8. While it is still locked, move the fifth
It opens on one side as shown in the figure. At this time, the rotation locking member 6 in the locking position is tilted as shown in FIG. 5 while maintaining the engagement between the convex cam surface 36 of the continuous inner cam section 40 and the protrusion 8, but the escape cam surface 30 and the protrusion 8, there is a distance D shown in FIG.
, the cam groove 20 will not damage the protrusion 8.

In the present invention described above, the body member and the lid member can be easily sealed and opened and separated by rotating the rotary lock member, and in particular, one rotary lock member can be set to the unlocked position. Even when the other rotary lock member is placed in the locking position and the lid member is left in a half-open state, the protrusion of the rotary lock member that engages with the cam groove provided therein will not be damaged.
