Abstract
A developer accommodating container includes first and second members, and first and second seals. The first member includes one end portion and the other end portion in a first direction. At least a part of the one end portion of the first seal is nipped between the first member and the second member in a state of being superposed on the second seal. The one end portion of the first seal includes first, second, third, and fourth ridge lines. At least one of a first corner formed by the first ridge line and the second ridge line and a second corner formed by the third ridge line and the fourth ridge line is nipped between the first member and the second member so as to be elastically deformed in a state of being superposed on the second seal.
Claims17
A developer accommodating container comprising:
- a first member configured to form an accommodating portion for accommodating developer;
- a second member mounted to the first member and configured to form the accommodating portion;
- a first seal extended along a first direction at a periphery of the accommodating portion and configured to seal between the first member and the second member by being nipped between the first member and the second member so as to be elastically deformed;
- and
- a second seal extended along a second direction crossing the first direction at the periphery of the accommodating portion and configured to seal between the first member and the second member by being nipped between the first member and the second member so as to be elastically deformed,
- wherein the first seal includes one end portion and the other end portion with respect to the first direction,
- wherein at least a part of the one end portion of the first seal is nipped between the first member and the second member so as to be elastically deformed in a state of being superposed on the second seal,
- wherein the one end portion of the first seal includes a first ridge line extending along the first direction, a second ridge line extending from the first ridge line along a direction crossing the first ridge line so as to be spaced from the accommodating portion in the second direction, a third ridge line extending from the second ridge line along a direction crossing the second ridge line, and a fourth ridge line extending from the third ridge line along a direction crossing the third ridge line so as to be spaced from the accommodating portion in the second direction,
- wherein a first corner formed by the first ridge line and the second ridge line is positioned closer to the other end portion of the first seal than a second corner formed by the third ridge line and the fourth ridge line is,
- wherein an interval between the first corner and the second corner in the first direction is shorter than a width, in the first direction, of a region where the first seal is superposed on the second seal, and
- wherein at least one of the first corner and the second corner is nipped between the first member and the second member so as to be elastically deformed in a state of being superposed on the second seal.
