Abstract

An additive container is configured to contain an additive to be added to a defibrated material therein and to be coupled to an intake port for introducing the additive of an additive supply device. The additive container includes a container that includes a discharge port and contains the additive, and a first shutter member that opens and closes the discharge port. The first shutter member enters an open state by rotating the container in a first direction around a central axis of the discharge port with respect to the first shutter member, and the first shutter member enters a closed state by rotating the container in a second direction opposite to the first direction with respect to the first shutter member from the open state.

First claim

What is claimed is:

1. An additive container configured to contain an additive to be added to a defibrated material therein and to be coupled to an intake port for introducing the additive of an additive supply device, the additive container comprising:
a container that includes a discharge port and contains the additive, the container further including a pair of first protruding pieces protruding outward from an outer peripheral side of the container, each of the first protruding pieces having a first protrusion that protrudes along a central axis of the discharge port; and
a first shutter member that opens and closes the discharge port, the first shutter member including a pair of second protruding pieces protruding outward from an outer peripheral side of the first shutter member, each of the second protruding pieces having a first surface, a second surface that faces in an opposite direction of the first surface, and a hole that penetrates through each of the second protruding pieces from the first surface to the second surface, wherein
the first shutter member enters an open state by rotating the container in a first direction around the central axis of the discharge port with respect to the first shutter member, and the first shutter member enters a closed state by rotating the container in a second direction opposite to the first direction with respect to the first shutter member from the open state,
the first protrusion and the hole restrict the first shutter member from rotating with respect to the container by the first protrusion being coupled to the hole from a side of the first surface,
the hole further restricts the first shutter member from rotating with respect to the additive supply device having a pair of second protrusions, by each second protrusion of the additive supply device being coupled to the hole from a side of the second surface,
the first protrusion which is being coupled to the hole is pushed outside of the hole by the each second protrusion in response to the each second protrusion being coupled to the hole from the side of the second surface, and
in a state where the rotation of the first shutter member with respect to the additive supply device is restricted by the hole being coupled to the each second protrusion, as the container is operated to rotate relative to the first shutter member, the open state and the closed state are switched.

2. The additive container according to claim 1 , wherein
the first shutter member includes a first opening portion that allows the additive to pass therethrough, and a first shielding portion that shields the additive, and
the discharge port includes a second opening portion that allows the additive to pass therethrough, and a second shielding portion that does not allow the additive to pass therethrough.

3. The additive container according to claim 2 , wherein
the additive container enters the open state in a state where the first opening portion overlaps with the second opening portion, and the additive container enters the closed state in a state where the first opening portion is shifted from the second opening portion.

4. The additive container according to claim 2 , wherein
a plurality of the first opening portions and a plurality of the first shielding portions are alternately provided around a rotation axis of the first shutter member, and
a plurality of the second opening portions and a plurality of the second shielding portions are alternately provided around a central axis of the discharge port.

5. The additive container according to claim 2 , wherein
the container includes a guide portion that guides the additive in the container to the second opening portion.

6. The additive container according to claim 5 , wherein
the guide portion is an inclined surface inclined toward the second opening portion.

7. The additive container according to claim 1 , wherein
the additive includes a binder that bonds fibers to each other.

8. The additive container according to claim 1 , wherein
the container includes a container body and a mouth member having the discharge port.
