OG exemplary drawing
 
1. A jig comprising:
a side surface body that has a tubular shape and that forms an insertion space into which an accommodation bag accommodating polycrystalline silicon fracture piece is to be inserted from above;
lift portions that are provided to the side surface body in order to lift the accommodation bag and the side surface body; and
a tray that is detachably provided to a bottom portion of the side surface body and that is configured to support the accommodation bag,
the tray being configured to, when the side surface body is lifted, be detached, so that an opening is formed at the bottom portion of the side surface body,
the opening being configured to form, when the accommodation bag is placed from above into an accommodation space in which the accommodation bag is to be accommodated, a placement path for the accommodation bag from the insertion space to the accommodation space,
wherein the opening fits in a cross section of the accommodation space cut along a plane substantially parallel to a horizontal plane.
 
2. A method for producing a polycrystalline silicon-packed box by packing, with use of the jig according to claim 1, the accommodation bag into a box provided with the accommodation space, the method comprising the steps of:
lifting, together with the jig, the accommodation bag inserted in the jig; and
causing the jig lifted and the accommodation bag lifted to move to a position above the predetermined accommodation space and placing the accommodation bag from above the accommodation space into the accommodation space.
