A resin lid for a container body with an opening in an upper part, including a body part that closes the opening and has an air hole, and a flap that includes a base, a hinge on a first end of the base, and a projection provided on a second end side of the base and fitted in the air hole. The flap is swingable around the hinge between a first position in which the projection fits in the air hole and a second position in which the air hole is open. The body part and flap are integrally formed. When the flap travels from the second to the first position, a tip of the projection comes into contact with a circumferential edge of the opening of the air hole on a side opposite the hinge, and the projection fits in the air hole as the flap elastically deforms.

1. A lid for attachment to a container body that has an opening in an upper part, comprising: a body part that closes the opening of the container body and has an air hole for communication with the inside of the container body, anda flap that includes a base, a hinge that is provided on a first end of the base and connected to the body part, and a projection that is provided on a second end side of the base and fitted in the air hole so as to be capable of sealing the air hole, and is configured to be swingable around the hinge between a first position in which the projection fits in the air hole and a second position in which the air hole is open,wherein the body part and the flap are integrally formed from resin, andwherein, the projection includes a surface on a distal tip of the projection, the surface being substantially parallel to the second end side of the base, and as the flap swings from the second position to the first position, the surface on the distal tip of the projection comes into contact with a circumferential edge of the air hole on a side opposite the hinge, the projection then, while moving toward the hinge side, fits into the air hole as the flap elastically deforms in response to downward pressure. 2. The lid according to claim 1, wherein a diameter of a tip of the projection is smaller than an inner diameter of the air hole, a diameter of the projection becomes greater toward a side of the base, and a diameter at a halfway point of the projection is greater than the inner diameter of the air hole. 3. The lid according to claim 1, wherein the flap further includes a first latching part that is attached to the second end side of the base,the body part further includes a second latching part that can engage with a portion of the first latch facing the hinge side, andthe first latching part and the second latching part engage when the flap is in the first position. 4. The lid according to claim 1, wherein the flap further includes at least one first rib that extends from the first end side toward the second end side of the base. 5. The lid according to claim 1, wherein the second end of the base of the flap is rounded, andthe base is provided with a second rib that extends in a second direction that is perpendicular to a first direction extending from the first end toward the second end, at a predetermined distance away from the second end toward the first end side. 6. A container comprising a container body that has an opening in an upper part and the lid according to claim 1 that is for attachment to the container body.
