Abstract
A developer container includes a pouch, a communication member, and a cap. A marking including an arrowhead part and a parting line are formed on an outer peripheral surface of the cap. A rear end of the arrowhead part is disposed between a first position that is a position 45° upstream from a reference position in a direction of rotation and a second position that is a position 45° downstream in the direction of rotation. The rear end of the arrowhead part overlaps the parting line.
Claims15
A developer container configured to accommodate a developer, comprising:
- a pouch including a bottom portion and a side portion extending from the bottom portion to form an opening;
- a communication member configured to make inside of the pouch communicate with outside, the communication member being fixed to the opening of the pouch;
- and
- a cap formed by injection molding and configured to be detached from the communication member by rotation with respect to the communication member, a marking indicating a direction of rotation to detach the cap from the communication member and a parting line extending in a direction along a rotation axis of the cap being disposed on an outer peripheral surface of the cap which is configured in a cylindrical shape, the marking including an arrowhead part formed to protrude from the outer peripheral surface, the arrowhead part including a rear end located upstream and a front end located downstream in the direction of rotation,
- wherein a direction connecting the opening and the bottom portion of the pouch is a first direction, a longitudinal direction of a cross-sectional shape of the pouch is a second direction, the second direction being orthogonal to the first direction, and a direction orthogonal to the first direction and the second direction is a third direction,
- wherein in a state of the cap attached to the communication member, the cap has a reference position on the outer peripheral surface, the reference position being a position in the second direction corresponding to where a thickness of the pouch in the third direction is maximized in a case where the pouch is viewed along the first direction, and
- wherein the rear end is positioned between a first position and a second position in the direction of rotation of the cap on the outer peripheral surface of the cap when installed on the communication member, the rear end being located to overlap the parting line, the first position end being a position 45° upstream from the reference position in the direction of rotation with the rotation axis as a center of rotation, the second position being a position 45° downstream from the reference position in the direction of rotation with the rotation axis as the center of rotation.

- wherein in a state of the cap attached to the communication member, the cap has a reference position on the outer peripheral surface, the reference position being a position in the second direction corresponding to where a thickness of the pouch in the third direction is maximized in a case where the pouch is viewed along the first direction,
- wherein at least a part of the arrowhead part is disposed along the outer peripheral surface between a first position and a second position in the direction of rotation, the first position being a position 45° upstream from the reference position in the direction of rotation with the rotation axis as a center of rotation, the second position being a position 45° downstream from the reference position in the direction of rotation with the rotation axis as the center of rotation, and
- wherein in a case where seen along the first direction, the parting line is positioned between a third position and a fourth position in the direction of rotation of the cap on the outer peripheral surface of the cap when installed on the communication member, the third position being located 45° upstream of a position where a second imaginary line intersects the outer peripheral surface of the cap, the second imaginary line being orthogonal to a first imaginary line connecting a position where the rear end intersects the outer peripheral surface and the center of rotation of the cap and passing through the center of the rotation of the cap, the fourth position being located 45° downstream of a position where the second imaginary line intersects the outer peripheral surface of the cap.
