Abstract: The break-off spout of the present invention includes: a spout main body (110) having a break-off section (150) formed via a weakened section (121) such that an annular section (152) having a through-hole formed therein protrudes to the tip side; and a pair of left and right cover members (160) integrally formed with the spout main body (110) via hinge sections provided below the weakened section (121). The pair of left and right cover members (160) are formed in a shape such that, when the cover members are engaged with each other, the cover members cover a portion of the spout main body (110) above the hinge sections including the break-off section (150). An insertion port (164) through which deformation means that deforms the annular section (152) and blocks the through-hole can be inserted is provided in the cover members (160).

Abstract: The purpose of this invention is to provide a warning display system on which a warning from an emergency vehicle is displayed as letters. When an emergency vehicle emits letter information of ‘please leave the left traffic lane’ by acoustic watermarking (electronic watermarking) together with siren sound on a congested expressway, among general vehicles, vehicles driving on a left lane and having devices capable of receiving the information in a range in which sound can reach change the lane to a center lane. Because among the general vehicles, vehicles driving on the center lane and having devices capable of receiving the information allow vehicles traveling on the left lane to move to the center lane, the left lane becomes empty and the emergency vehicle can smoothly drive on the left lane.
