Abstract
Claims
1. A container body comprising a bottom portion, a cylindrical main body side wall portion rising upward from the outer edge of the bottom portion, and a main body flange portion having an inclined portion that slopes downward toward the side from the upper end of the main body side wall portion, with an opening defined by the upper end of the main body side wall portion, A lid comprising a lid surface that covers the opening, and a lid side wall portion that is cylindrical in shape extending vertically from the outer edge of the lid surface and fits inside the side wall portion of the main body, which can be attached to the container body to seal the container body, while being removable from the container body, A hinge portion provided around the periphery of the lid side wall portion, having a single rotation center that extends linearly in the first transverse direction intersecting the vertical direction, A flap is positioned facing the inclined portion in the vertical direction, has a projection that curves downward in a convex shape, is connected to the lid via the hinge portion, extends in a second transverse direction intersecting the vertical direction and the first transverse direction, and is rotatable around the rotation center of the hinge portion between a first position that allows the lid to seal the container body and a second position that forms a gap between the lid and the container body, Equipped with, The inclined portion has at least one of a curved portion that extends downward while curving convexly toward the side, and a planar portion that extends inclined downward toward the side. The flap is configured such that when it rotates in one direction from the first position to the second position, the projection pushes against the curved or flat portion, and using the contact point between the projection and the curved or flat portion as a fulcrum and the hinge as the point of application, it pushes up the lid and releases the seal between the lid and the container body by lever principle, and when it is in the second position, it is sandwiched between the container body and the lid to maintain the gap. The inclined portion has a recess formed therein that fits with the tip of the flap. A container in which, when the flap and the recess are fitted together, the raised portion defining the recess restricts the flap from rotating in the opposite direction to the one direction, and the gap is maintained by holding the flap in the second position.
2. The container according to claim 1, wherein the angle between the direction in which the inclined portion extends and the second lateral direction is 45 degrees or less.
3. The inclined portion has both the curved portion connected to the main body side wall and the planar portion connected to the side of the curved portion. The container according to claim 1 or 2, wherein when the flap rotates in one direction from the first position to the second position, the projection pushes against the curved portion, and the contact point between the projection and the curved portion acts as a fulcrum, and the hinge portion acts as the point of application of force, thereby pushing up the lid and releasing the seal between the lid and the container body by the principle of leverage.
4. The lid surface is flat, The container according to claim 1 or 2, wherein the lid side wall portion is cylindrical, rising upward from the outer edge of the lid surface.
