Abstract
A liquid absorber includes a case, a first liquid absorption member stored in the case, and a second liquid absorption member stored in the case. The case has an opening. The first liquid absorption member absorbs a portion of a liquid. The second liquid absorption member absorbs a portion of the liquid. The second liquid absorption member is disposed adjacent to the first liquid absorption member and is closer to the opening than is the first liquid absorption member. The first liquid absorption member and the second liquid absorption member include fiber substrates and a liquid-absorbent resin, the liquid-absorbent resin being liquid-absorbent resin particles.
Claims7
A liquid absorber comprising:
- a case having an opening;
- a first liquid absorption member stored in the case, the first liquid absorption member being a member that absorbs a portion of a liquid;
- and
- a second liquid absorption member stored in the case, the second liquid absorption member being a member that absorbs a portion of the liquid, the second liquid absorption member being disposed adjacent to the first liquid absorption member and being closer to the opening than is the first liquid absorption member, wherein
- the first liquid absorption member and the second liquid absorption member include fiber substrates and a liquid-absorbent resin, the liquid-absorbent resin being liquid-absorbent resin particles,
- the first liquid absorption member includes a first bonded portion in which at least some of the fiber substrates are bonded to one another, the first bonded portion being disposed in a surface of the first liquid absorption member, the surface being closer to the second liquid absorption member than is another surface of the first liquid absorption member,
- the second liquid absorption member includes a second bonded portion in which at least some of the fiber substrates are bonded to one another, the second bonded portion being disposed in a surface of the second liquid absorption member, the surface being closer to the opening than is another surface of the second liquid absorption member,
- the at least some of the fiber substrates in the first liquid absorption member are bonded to a bottom portion of the case and a sidewall portion of the case with at least one of a bonding force of a water-soluble adhesive and an adhesive force of the liquid-absorbent resin, and
- the at least some of the fiber substrates in the second liquid absorption member are bonded to a sidewall portion of the case with the at least one of a bonding force of a water-soluble adhesive and an adhesive force of the liquid-absorbent resin.
