## Abstract

A feeding container includes a feeding mechanism having a sleeve. In the feeding container, a first groove through which a projection formed in a holding member that holds a coating material passes and a second groove that extends from the first groove to an end surface of the sleeve are formed on an inner surface of the sleeve, and the first groove has a projection holding portion which is configured to accept the projection and disposed at a position away along the first groove from a connection portion of the first groove and the second groove.

## Claims

### Claim 1

A feeding container comprising:
a feeding mechanism having a sleeve,
wherein a first groove through which a projection formed in a holding member that holds a coating material passes and a second groove that extends from the first groove to an end surface of the sleeve are formed on an inner surface of the sleeve,
wherein the first groove has a projection holding portion which is configured to accept the projection and disposed at a position away along the first groove from a connection portion of the first groove and the second groove,
wherein the feeding mechanism includes:
a first cylindrical member interposed between the sleeve and the holding member: and
a second cylindrical member positioned outside the first cylindrical member,
wherein one of the first cylindrical member and the second cylindrical member includes an inclined rib having an inclined surface inclined with respect to an axial direction of the first cylindrical member,
wherein another one of the first cylindrical member and the second cylindrical member includes a rib that is configured to engage with the inclined rib in a circumferential direction of the second cylindrical member, and
wherein, when the projection enters the projection holding portion, a position of an end portion of the rib in the axial direction coincides with a position of the inclined surface in the axial direction.

### Claim 2 (depends on 1)

The feeding container according to claim 1, wherein a convex portion is formed in the second groove of the sleeve.

### Claim 3 (depends on 1)

The feeding container according to claim 1, wherein the second groove has a widened portion in which a width of the second groove increases toward the end surface of the sleeve.

### Claim 4 (depends on 3)

The feeding container according to claim 3, wherein
the widened portion is defined by a first surface and a second surface that are inclined with respect to an axial direction of the sleeve, and
an end position of the first surface in the axial direction of the sleeve on a side opposite to the end surface is different from an end position of the second surface in the axial direction of the sleeve on a side opposite to the end surface.

### Claim 5 (depends on 4)

The feeding container according to claim 4, wherein
the widened portion is partially defined by the second surface that is inclined with respect to the axial direction of the sleeve, and
a position of the projection holding portion in the axial direction of the sleeve is within a range of the second surface in the axial direction of the sleeve.

### Claim 6 (depends on 3)

The feeding container according to claim 3, wherein
the widened portion is partially defined by a second surface that is inclined with respect to an axial direction of the sleeve, and
a position of the projection holding portion in the axial direction of the sleeve is within a range of the second surface in the axial direction of the sleeve.

### Claim 7 (depends on 1)

The feeding container according to claim 1, wherein the second groove has a widened portion in which a width of the second groove increases toward the end surface of the sleeve.
