There is used a container which includes a first member which serves as a lid portion, a second member which serves as a container portion, and resin with which a flow path, which is formed between the first member and the second member when the first member and the second member come into contact with each other, is filled, the resin bonds the first member and the second member to each other by reaching a filling target position after flowing in from an inflow opening to the flow path, and an opening portion exposed to an exterior of the container is provided at a position where the resin having flowed in from the inflow opening flows out beyond the filling target position in the flow path.

A mold for molding a sleeve of protective material onto a wiring harness. The mold includes: a mold body; an inlet; an outlet; and a channel extending through the mold body and connecting the inlet to the outlet. The mold also has a plurality of centralizing spacers, configured to hold the wiring harness centrally within the channel as the wiring harness extends between the inlet and the outlet. The mold also includes an injection port and an exit port arranged to convey fluid sleeve material into and out of the channel. The channel follows a path along a helical curve as it extends between the inlet and the outlet of the mold.
