Abstract

A liquid absorber including a liquid absorbent body configured to include a small piece aggregate including a plurality of small pieces having a fiber base material containing a fiber and a water absorbent resin, and a container that includes a wall portion defining a storage space accommodating the liquid absorbent body, and a protrusion portion provided to protrude from the wall portion toward the storage space, in which when a minimum separation distance between a tip end of the protrusion portion and a structure different from the protrusion portion is L1, and an average value of a distance between farthest ends of the small piece is L2, 0<L1/L2≤1.80 is satisfied.

First claim

What is claimed is:

1. A liquid absorber comprising:
a liquid absorbent body configured to include a piece aggregate including a plurality of pieces having a fiber base material containing a fiber and a water absorbent resin; and
a container that includes
a wall portion defining a storage space accommodating the liquid absorbent body and
a protrusion portion provided to protrude from the wall portion toward the storage space, wherein

0<L1/L2≤1.80, wherein L1 is a minimum separation distance between a tip end of the protrusion portion and a structure different from the protrusion portion, and L2 is an average value of a distance between farthest ends of a piece of the pieces.

2. The liquid absorber according to claim 1 , wherein
the protrusion portion is provided to protrude from a bottom surface of a container main body, the bottom surface facing the storage space.

3. The liquid absorber according to claim 2 , wherein
a height of the tip end of the protrusion portion from the bottom surface is 50% or more of a depth of the container main body.

4. The liquid absorber according to claim 1 , wherein
the protrusion portion is provided to protrude from a side surface of a container main body, the side surface facing the storage space.

5. The liquid absorber according to claim 1 , wherein
the container includes a partition portion that partitions the storage space into a first storage space and a second storage space, a filling density of the piece in the second storage space being lower than a filling density of the piece in the first storage space, and
the partition portion is formed from one or more of each of a plurality of protrusion portions each of which is the protrusion portion arranged to separate the second storage space from the first storage space.

6. The liquid absorber according to claim 5 , wherein
the partition portion includes a communication portion through which a liquid passes between the first storage space and the second storage space.

7. The liquid absorber according to claim 5 , wherein
the container includes a supply portion that supplies a liquid to the second storage space.

8. The liquid absorber according to claim 1 , wherein
the container is provided with a plurality of protrusion portions, each of which is the protrusion portion provided to protrude from the wall portion toward the storage space, and
the L1 is a distance between tip ends of the protrusion portions adjacent to each other.

9. The liquid absorber according to claim 1 , wherein
the L1 is a distance between the tip end of the protrusion portion and the wall portion.
