To provide a filler introduction apparatus which can introduce a filler into a bag without using a power source, such as electric power supply, and separate the bag from the apparatus without manual operation.
The filler introduction apparatus is inserted into an inlet of the bag to introduce such a solid material as grain or powder, gelled material, or liquid material into the bag. The apparatus includes a cylinder, a guide portion which extends upward from the upper end of the cylinder while expanding in diameter to guide a charged granular material to the cylinder, and hooking portions which are disposed on the outer periphery of the guide portion or the cylinder. Each hooking portion has a bar-like balance, a hook provided at one end of the balance, a pivot enabling the turning of the balance, a support supporting the pivot, and a resilient material that connects the other end of the balance and the support to draw the balance. As the balance turns on the pivot by the gravity of the bag, the hook is released from engagement with a hole or loop.
