BACKGROUND ART Conventionally, containers have been used that squirt out the liquid contents of various food seasonings, cosmetics, medicines, and the like by squeezing them.
There is also known a spouting cap that can spray the contents in a mist over a relatively wide area by squeezing (see, for example, Patent Document 1).

However, in the case of the cap for a squeeze container disclosed in Patent Document 1, the spouting tube of the spouting cap is sealed with a seal part that is vertically disposed from the lid body, and the liquid inside the pouring cap is sealed from the spouting port through the spouting tube during distribution. There was a problem with maintaining airtightness during distribution.
Additionally, when a sealing member such as an aluminum seal is welded to the nozzle to maintain airtightness during distribution, the heat during welding deforms the nozzle and prevents the liquid from being properly sprayed into a mist. The problem was that it disappeared.
