A liquid absorbing sheet includes: a receiving base material which has a liquid permeability and which includes a first base material, a second base material, and a bonding portion at which the first base material and the second base material are bonded to each other at margins thereof, the first base material and the second base material each being composed of a material including fibers; and a water absorbing resin which has a water absorbing property, which is swelled in association with water absorption, and which is received in a portion between the first base material and the second base material surrounded by the bonding portion. In the liquid absorbing sheet described above, the bonding portion is at least partially broken when the water absorbing resin is swelled.

Liquid absorbing sheet

A liquid container includes: a case having a liquid introduction port through which liquid is introduced and a storage portion that stores the liquid; and an absorber stored in the case and configured to absorb the liquid. The absorber includes multiple absorbent resins that swell by absorbing the liquid and a substrate that supports the absorbent resins and allows the liquid to permeate therethrough. With the absorbent resins swelling by absorbing the ink, at least some of the absorbent resins are spaced apart from the adjacent absorbent resins.

Liquid container

A liquid ejecting apparatus includes: a liquid ejecting head configured to eject a liquid; a liquid flowing portion coupled to the liquid ejecting head and configured to flow the liquid; and a frame that houses the liquid ejecting head and the liquid flowing portion. The frame is provided with a passage hole configured to pass the liquid flowing portion along a depth direction. when viewed in the depth direction, a portion of the liquid flowing portion disposed outside the passage hole is configured to be deformed.

Liquid ejecting apparatus

An ink absorber includes: a plurality of ink absorbent bodies that are elongated and absorb waste liquid of an ink ejected from a liquid ejecting head; and an accommodating container that accommodates the plurality of ink absorbent bodies, in which the plurality of ink absorbent bodies are arranged such that a longitudinal direction thereof extends vertically. Occupancy of the plurality of ink absorbent bodies in a region in which the ink absorbent bodies are arranged in the accommodating container is desirably 50% or more and 99% or less when the ink absorbent bodies are dry.

Ink absorber and printing apparatus

Provided is a powder supply device including a storage tank in which an internal space that stores powder and a discharge port that discharges the powder from the internal space to outside are formed, a roller that has an outer peripheral surface formed of a rough surface and is rotatably provided, in the discharge port, to face both the internal space and the outside, and a doctor blade that is provided at the discharge port and faces the outer peripheral surface of the roller. The internal space includes a first chamber into which the powder is charged and a second chamber in which the doctor blade is disposed. The first chamber communicates with the second chamber via an opening. A partition member that restricts the width of the opening is provided between the first chamber and the second chamber. The powder charged into the first chamber moves to the second chamber through the opening.

Powder supply device

A liquid absorber includes a container and an absorbing unit. The container has an opening and collects a liquid. The absorbing unit is an assembly of porous absorbent blocks, each containing fibers and a polymeric absorbent, and is in the container with spaces between the porous absorbent blocks. Each of the porous absorbent blocks has a first component and a second component. The first component is porous and has a density of 0.05 [g/cm] or more and 0.50 [g/cm] or less. The second component has a higher polymeric absorbent content than the first component.

Liquid absorber, liquid-absorbing sheet, liquid absorbent, and image-forming apparatus

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.

Liquid absorber and method for producing same, and liquid ejection apparatus

A liquid absorber includes a plurality of small chips. Individual ones of the small chips include a first substrate containing fibers, a second substrate containing fibers, and an absorbent resin supported between the first substrate and the second substrate. The first substrate contains an ion scavenger.

Liquid absorber, liquid absorbing unit, and liquid ejection apparatus

A liquid absorbent body according to the present disclosure includes a water absorbent resin and a pulp fiber, in which an evaporation rate of a pure water until elapse of 360 minutes after the pure water is absorbed is 0.0006 g/(cm&#xb7;min) or more and 0.0020 g/(cm&#xb7;min) or less, when the pure water of 20 mL is absorbed into the liquid absorbent body of 2.57 g, under an environment of 60&#xb0; C. and 20% RH. It is preferable that the liquid absorbent body is configured to include an aggregate of small pieces in which a fiber base material containing the pulp fiber carries the water absorbent resin.

Liquid absorbent body, liquid absorber, and liquid treatment apparatus

A liquid absorber includes a plurality of small chips. Individual ones of the small chips include a first substrate containing fibers, a second substrate containing fibers, an absorbent resin supported between the first substrate and the second substrate, and an ion exchange resin supported between the first substrate and the second substrate. At least one of the absorbent resin and the ion exchange resin is exposed at an end face of the small chips.

A liquid absorber includes a liquid absorption member and a case. The liquid absorption member absorbs liquid. The liquid absorption member includes materials that include a fiber and a liquid-absorbent resin. The liquid absorption member is stored in the case. The case has an opening portion. The materials of the liquid absorption member are bonded together in at least a portion of a surface of the liquid absorption member. The surface is a surface adjacent to the opening portion.

Liquid absorber and liquid ejection apparatus

A liquid absorber includes a liquid absorption member, a case, and a cover. The liquid absorption member absorbs liquid. The liquid absorption member includes a fiber and a liquid-absorbent resin. The liquid absorption member is stored in the case. The cover covers the liquid absorption member. The cover includes through-holes through which the liquid is to pass.
