Abstract: A material supply device and a spout mounted in a bag body that can efficiently output a material in an accommodation space when the material accommodated in the accommodation space of the bag body is output using a squeeze unit such as rollers, and can inhibit a decrease in the strength of the bag body which is caused by contact between the squeeze unit and the spout. A material supply device according to the present invention includes a bag assembly including a bag body that includes an accommodation space which accommodates a material, and a spout that includes a passage which delivers the material in the accommodation space to an outside, and is mountable in the bag body; and a squeeze unit that squeezes the bag body toward the spout to move the material in the accommodation space toward the spout.

Abstract: Providing a viscous material feed apparatus and a viscous material feed method capable of further reducing a viscous material remaining in a container, e.g., a bag, housing the viscous material. A viscous material feed apparatus according to the present invention includes: a container (10) configured to include a bag body (11) with a housing space configured to house a viscous material and a spout (20) with a passage configured to deliver the viscous material in the housing space to outside; a squeeze portion (30) configured to squeeze the bag body toward the spout and move the viscous material in the housing space toward the spout; and a nozzle (40) having a hollow shape, the nozzle being configured to be freely inserted into the passage of the spout and withdrawn from the spout, the nozzle being configured to deliver the viscous material collected at the spout to outside.
