container including a neck portion with an opening and a trunk portion and configured to store the extraction target and a liquid, a filter arranged on the opening of the neck portion and configured to restrict leakage of the extraction target, and a driving unit configured to change a posture of the extraction container from a first posture in which the neck portion is located on an upper side to a second posture in which the neck portion is located on a lower side. ## Claims ### Claim 1 An extracting apparatus for extracting a beverage liquid from an extraction target, comprising: an extraction container configured to store the extraction target and a liquid, the extraction container including a first hole through which the beverage liquid made from the extraction target and the liquid in the extraction container passes from inside of the extraction container to outside of the extraction container and a second hole; a first operation unit configured to perform an open/close operation of a first member which opens/closes the first hole of the extraction container; a second operation unit configured to perform an open/close operation of a second member which opens/closes the second hole of the extraction container; and a posture-change unit configured to change a posture of the extraction container with the first hole closed by the first member and the second hole closed by the second member from a first posture in which the first hole is oriented upwardly in a vertical direction to a second posture in which the first hole is oriented downwardly in the vertical direction, wherein the beverage liquid is sent from the first hole of the extraction container with the second posture, in the second posture, the second hole is positioned above the beverage liquid in the extraction container, the extraction container is formed such that a height that the extraction target occupies in the extraction container in the second posture is larger than in the first posture, and in the second posture, the first hole is opened by operating the first member after the second hole is opened by operating the second member. ### Claim 2 An extracting method of extracting a beverage liquid from an extraction target, comprising: a first immersion step of immersing, in a liquid in an extraction container with a first posture, the extraction target accumulated in the extraction container in a first form; a first posture-change step of changing a posture of the extraction container from the first posture to a second posture after the first immersion step; and a sending step of sending the beverage liquid made from the extraction target and the liquid in the extraction container through a first hole of the extraction container from inside of the extraction container to outside of the extraction container with the second posture, wherein the extraction container in the posture-change step is in a state that the first hole is closed by a first member and a second hole of the extraction container is closed by a second member, in the second posture, the second hole is positioned above the beverage liquid in the extraction container, in the sending step, the first hole is opened by operating the first member after the second hole is opened by operating the second member, the extraction target is accumulated in a second form in the extraction container with the second posture, the second form is a form in which a height that the extraction target occupies in the extraction container is larger than in the first form, and in the sending step, the beverage liquid which passes through the extraction target accumulated in the second form is sent to outside of the extraction container through the first hole. ### Claim 3 (depends on 2) The extracting method according to claim 2, wherein the extraction container includes a thick portion and a thin portion, the thick portion has an internal width larger than an internal width of the thin portion, in the first posture, the extraction target accumulates in the thick portion, and in the second posture, the extraction target accumulates in the thin portion. ### Claim 4 (depends on 2) The extracting method according to claim 2, wherein the beverage liquid is a coffee. ### Claim 5 (depends on 1) The extracting apparatus according to claim 1, wherein the beverage liquid is a coffee. ### Claim 6 (depends on 1) The extracting apparatus according to claim 1, further comprising a spring that biases the first member in a closing direction, and wherein the first operation unit is driven by a motor. ### Claim 7 (depends on 1) The extracting apparatus according to claim 1, wherein the extraction container includes a main body having an opening and a lid unit configured to open/close the opening, the main body includes a neck portion having an internal width smaller than a width of the opening, in the second posture, the extraction target accumulates at least in the neck portion, and the posture-change unit includes an arm member configured to detachably hold the main body. ### Claim 8 (depends on 7) The extracting apparatus according claim 7, wherein the arm member includes a C-shaped clip portion configured to detachably hold the main body. ### Claim 9 (depends on 7) The extracting apparatus according to claim 7, wherein the lid unit includes the first hole, and the first operation unit is configured to perform the open/close operation of the first member and also an open/close operation of the lid unit for the opening of the main body. ### Claim 10 (depends on 1) The extracting apparatus according to claim 1, wherein the first operation unit is configured to perform the open operation of the first member after a second immersion type extraction in a state that the extraction target is accumulated in the extraction container with the second posture. ### Claim 11 (depends on 1) The extracting apparatus according to claim 1, wherein the posture-change unit also changes the posture of the extraction container from the first posture to the second posture after a liquid for cleaning the extraction container is introduced into the extraction container with the first posture. ### Claim 12 (depends on 2) The extracting method according to claim 2, further comprising a second immersion step of immersing, in the liquid in the extraction container with the second posture, the extraction target accumulated in the extraction container in the second form before the sending step. ### Claim 13 (depends on 2) The extracting method according to claim 2, further comprising a second posture-change step of changing the posture of the extraction container from the first posture to the second posture after a liquid for cleaning the extraction container is introduced into the extraction container with the first posture. ### Claim 14 (depends on 1) The extracting apparatus according to claim 1, wherein the posture-change unit changes the posture of the extraction container from the first posture to the second posture after a first immersion type extraction for a predetermined time in a state that the extraction target is accumulated in the extraction container with the first posture. ### Claim 15 (depends on 2) The extracting method according to claim 2, wherein in the first immersion step, the extraction target accumulated in the extraction container in the first form is immersed in the liquid for a predetermined time.
