## Abstract

A lipstick container, including: a container main body and a cap, in which the container main body includes a middle plate body provided with a screw pin, a middle cylindrical body, an inner cylindrical body in which a spiral groove into which the screw pin screwed is formed, and an outer cylindrical body, and one of the middle plate body and the inner cylindrical body moves up to a fixed position through rotation of the outer cylindrical body, and once the one reaches the fixed position, the other of the middle plate body and the inner cylindrical body moves up through rotation of the outer cylindrical body.

## Claims

### Claim 1

A lipstick container, comprising:
a container main body; and
a cap mounted on the container main body,
wherein the container main body includes
a middle plate body in which lipstick is stored and is provided with a screw pin,
a middle cylindrical body which guides the middle plate body such that the middle plate body can move vertically but cannot rotate,
an inner cylindrical body in which a spiral groove into which the screw pin of the middle plate body is screwed is formed, and which vertically moves the middle plate body by rotating on an outer circumference of the middle cylindrical body, and
an outer cylindrical body, an inner circumferential surface of which is screwed into an outer circumferential surface of the inner cylindrical body, and
wherein one of the middle plate body and the inner cylindrical body moves up to a fixed position through rotation of the outer cylindrical body, and once the one reaches the fixed position, the other of the middle plate body and the inner cylindrical body is moved up through rotation of the outer cylindrical body.

### Claim 2 (depends on 1)

The lipstick container according to claim 1,
wherein an operation resistance when the inner cylindrical body is screwed into the outer cylindrical body is larger than an operation resistance when the screw pin of the middle plate body is screwed into the spiral groove of the inner cylindrical body.

### Claim 3 (depends on 2)

The lipstick container according to claim 2,
wherein the inner cylindrical body includes a screw portion screwed into the outer cylindrical body, and
wherein an interfering projection is formed in the screw portion.

### Claim 4 (depends on 3)

The lipstick container according to claim 3,
wherein a plurality of the interfering projections are formed intermittently along the screw portion.

### Claim 5 (depends on 3)

The lipstick container according to claim 3,
wherein the interfering projection is formed in a valve actuator elastically deformable in a radial direction.

### Claim 6 (depends on 1)

The lipstick container according to claim 1,
wherein an operation resistance when the inner cylindrical body is screwed into the outer cylindrical body is smaller than an operation resistance when the screw pin of the middle plate body is screwed into the spiral groove of the inner cylindrical body.

### Claim 7 (depends on 1)

The lipstick container according to claim 1,
wherein the inner cylindrical body includes a screw portion screwed into the outer cylindrical body, and
wherein a pitch of the spiral groove is larger than that of the screw portion.

### Claim 8 (depends on 7)

The lipstick container according to claim 7,
wherein an interfering projection is formed in the screw portion.

### Claim 9 (depends on 8)

The lipstick container according to claim 8,
wherein a plurality of the interfering projections are formed intermittently along the screw portion.

### Claim 10 (depends on 1)

The lipstick container according to claim 1,
wherein the inner cylindrical body includes a screw portion screwed into the outer cylindrical body, and
wherein a pitch of the spiral groove is smaller than that of the screw portion.

### Claim 11 (depends on 1)

The lipstick container according to claim 1,
wherein the inner cylindrical body has a planar portion provided at an upper end portion of the spiral groove, the planar portion along a direction orthogonal to a direction along a central axis of the inner cylindrical body.

### Claim 12 (depends on 11)

The lipstick container according to claim 11,
wherein the inner cylindrical body includes a screw portion screwed into the outer cylindrical body, and
wherein an interfering projection is formed in the screw portion.
