## 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nozzle (40) having a hollow shape, the nozzle being configured to be freely inserted into the passage of the spout and withdrawn from the spout, the nozzle being configured to deliver the viscous material collected at the spout to outside.

## Claims

### Claim 1

A viscous material feed apparatus comprising:
a container configured to include a bag body with a housing space configured to house a viscous material and a spout with a passage configured to deliver the viscous material in the housing space to outside;
a squeeze portion configured to squeeze the bag body toward the spout and move the viscous material in the housing space toward the spout; and
a nozzle having a hollow shape, the nozzle being configured to be freely inserted into the passage of the spout and withdrawn from the spout, the nozzle being configured to deliver the viscous material collected at the spout to outside,
wherein the nozzle has a contact portion having a shape corresponding to a shape of the squeeze portion.

### Claim 2 (depends on 1)

The viscous material feed apparatus according to claim 1, wherein the spout has a contact portion having a shape corresponding to a shape of the squeeze portion.

### Claim 3 (depends on 1)

The viscous material feed apparatus according to claim 1, further comprising a pumping portion configured to pump the viscous material delivered through the nozzle.

### Claim 4 (depends on 1)

The viscous material feed apparatus according to claim 1, wherein the bag body further comprises a reduction portion in which a cross-sectional area of the housing space is reduced toward the spout.

### Claim 5 (depends on 1)

A viscous material feed method using the viscous material feed apparatus according to claim 1, the method comprising:
inserting the nozzle having a hollow shape to the passage inside the spout attached to the bag body housing the viscous material delivered to outside;
squeezing the bag body to deliver the viscous material through the nozzle inserted into the passage of the spout; and
withdrawing the nozzle from the spout of the bag body and inserting the nozzle into a different spout attached to a different bag body to deliver the viscous material housed in the different bag body.
