Nozzle insertion member, powder container, and image forming apparatus
First Claim
1. A powder container for use with an image forming apparatus, the powder container comprising:
- a nozzle insertion opening into which a conveying nozzle of the image forming apparatus is inserted;
an obstacle that is biased toward a closing position for closing the nozzle insertion opening and that opens the nozzle insertion opening along with insertion of the conveying nozzle;
a seal arranged on a circumference of the nozzle insertion opening; and
a portion having an inner cylindrical space in which the seal is arranged, the portion including a plurality of convexes that are arranged along an outer circumference of the seal,wherein a vertical surface of the seal on a downstream side in an attachment direction in which the powder container is attached protrudes toward the downstream side in the attachment direction relative to ends of the convexes on the downstream side in the attachment direction.

Abstract
A nozzle insertion member is in a powder container that includes a nozzle insertion opening into which a conveying nozzle is inserted. The nozzle insertion member includes an opening/closing structure to move to an opening position to open the nozzle insertion opening by being pressed by the inserted conveying nozzle, and to a closing position to close the nozzle insertion opening when the conveying nozzle is separated from the nozzle insertion member, and a seal arranged at the nozzle insertion opening and including a through hole into which the conveying nozzle is insertable. The opening/closing structure includes a front cylindrical portion to contact with an inner surface of the through hole, and a slide area formed on another side relative to the front cylindrical portion. W1<W4 is satisfied, where W1 is an inner diameter of the through hole, and W4 is an outer diameter of the slide area.
