Abstract

A powder container includes a body and a pair of walls that blocks one longitudinal end of the body and the other longitudinal end of the body. Powder is accommodated within the powder container which is mounted to an apparatus using the powder in a posture where a longitudinal direction of the body is a transverse direction of the apparatus. The powder container has an opening, through which the powder is supplied to the apparatus, formed in a lower position of the body in a posture where the powder container is mounted to the apparatus. The powder container includes a shutter and a shield. The shutter is, prior to mounting the powder container to the apparatus, in a closed location to block the opening and, when the powder container is mounted, is moved along an outer peripheral surface of the body to an opened location to open the opening.

First claim

What is claimed is:

1. A powder container comprising:
a body; and
a pair of walls that blocks one longitudinal end of the body and the other longitudinal end of the body, powder being accommodated within the powder container and the powder container being mounted to an apparatus that uses the powder,
wherein each of the pair of walls includes:
a first locking portion having a cantilever shape and configured to be prevented from being withdrawn from the apparatus such that the powder container is pulled out from the apparatus when the powder container is mounted to the apparatus; and
a second locking portion configured to be prevented from being withdrawn such that the powder container is not withdrawn from the apparatus by being pressed by a movable member of the apparatus by the movement of the movable member of the apparatus after the powder container is prevented from being withdrawn by the first locking portion,

wherein
the powder container receives a repulsive force relatively stronger in a direction of pulling out the powder container from the apparatus at the vicinity of a first wall side than at the vicinity of a second wall side when the powder container is mounted to the apparatus, and
the first locking portion provided in the first wall has the cantilever shape where the distance between the fixed end and the free-end of the cantilever shape is relatively longer than that in the first locking portion provided in the second wall,
in the vicinity of the first wall of the body, there are provided an opening through which the powder within the powder container is supplied to the apparatus, and a shutter that is, prior to mounting the powder container to the apparatus, disposed in a closed location to block the opening, and is, in the state where the powder container is mounted, moved along the outer peripheral surface of the body to an opened location to open the opening, and
in the state where the powder container is mounted to the apparatus, the shutter receives an action from the movable member of the apparatus to be moved to the opened location.

2. The powder container according to claim 1 , wherein the first wall of the pair of walls that blocks the one end, constitutes a container body that receives the powder in a state where the other end is opened, together with the body,
the second wall of the pair of walls that blocks the other end is a cover that blocks the other end after the powder is accommodated within the container body,
the first locking portion provided in the first wall has the cantilever shape that extends along the outer wall surface of the first wall in a direction of crossing a longitudinal direction of the body, and
the first locking portion provided in the second wall has the cantilever shape that protrudes in the longitudinal direction of the body from the outer wall surface of the second wall.

3. The powder container according to claim 1 , wherein
the first locking portion provided in the first wall is a locking portion that is prevented from being withdrawn by a locking force relatively stronger than that of the first locking portion provided in the second wall.

4. An image forming apparatus which is mounted with a powder container according to claim 1 to form an image using the powder accommodated within the powder container.
