In addition to the configuration of the first or second problem solving means, at least one of the plurality of rods has a protrusion or a cilia.
A packaging body according to a fourth problem solving means is formed between a container having a spout provided with any one of the first to third problem solving means and a plurality of bars housed in the container and viewed from above. And a liquid in which a solid larger than the gap formed is deposited.

According to the spout of the first problem solving means, since the plurality of bars belong to any of a plurality of groups having different heights as viewed from the side, the number of bars arranged at the same height is Since the opening at the same height as viewed from the side is larger because the number is less than the total number, and in order to stop the agglomerates etc. with the rod, especially film-like agglomerates etc. are caught so as to be wound around the rod, There is an effect that clogging hardly occurs due to film-like aggregates.
According to the spout of the second problem solving means, since the plurality of bars overlap with each other when viewed from the top surface, the overlapping portions can be molded with a mold that can be broken up and down and overlapped Since they are connected to each other, it is not necessary to insert the mold between the overlapping parts, so it can be easily molded at once with a mold that is divided into upper and lower parts, and the cost can be reduced. There is.
According to the spout of the third problem solving means, the aggregates entangled by the sticks having protrusions or cilia are less likely to fall off, and the effect of preventing the aggregates from passing through can be improved.
According to the package of the fourth problem solving means, there is an effect that the liquid can be poured out while filtering the solid generated from the liquid, and the amount of the usable liquid can be increased compared to the conventional case because clogging is difficult.
