## Abstract

Provided is a flower pot generating little root rot by controlling a water supply rate for a relatively long period of time even using a simple structure regardless of its size. The flower pot includes: an outer pot body; an inner pot body housed in the outer pot body with a gap as a water supply portion; a vertical position changeable member provided in a predetermined place to connect the outer pot body and the inner pot body; a flange provided on an upper end surface of the sidewall of the inner pot body; and a sealing portion formed of an elastic member and provided between the flange and the upper end surface of the sidewall of the outer pot body, in which water stored in the water supply portion is supplied to the inner pot body through a nonwoven fabric member.

## Claims

### Claim 1

A flower pot comprising:
an outer pot body;
an inner pot body housed in the outer pot body with a gap as a water supply portion;
a folding portion provided on an upper end surface of a sidewall of the inner pot body; and
a sealing portion formed of an elastic member and provided between the folding portion and an upper end surface of a sidewall of the outer pot body,
wherein water stored in the water supply portion is supplied to the inner pot body through a nonwoven fabric member,
a planar shape of the nonwoven fabric member is a circular shape including a protruding portion, and a cross-sectional shape of the nonwoven fabric member is a planar member having the same thickness a through-hole is provided in a bottom of the inner pot body and the nonwoven fabric member is inserted inside the inner pot body, wherein the protruding portion reaches the gap at the water supply portion through the through-hole,
an inner bottom surface of the outer pot body is provided with a first threaded portion and an outer bottom surface of the inner pot body is provided with a second threaded portion as a vertical position changeable member, and
the inner bottom surface of the outer pot body and the outer bottom surface of the inner pot body are connected to each other with the first threaded portion and the second threaded portion.
