反思使用調味醬料的行為。有時候倒番茄醬時，很不巧地量太少了，以至於無法立即地將番茄醬壓擠出來。這時可能將罐子倒過來讓它緩慢地流出，或者乾脆大力地擠壓。然而原本美好的早餐時光即被破壞，即使不是生活中巨大的問題，但我們可以擁有更美好的時光。

無論濃稠醬料的存量為多少都相當方便。以蕃茄醬為例，醬量多時就如同平常的使用模式一樣由上開啟；醬量少時就只要打開底部蓋子。無論蕃茄醬是多或少，對於"Dual-open Bottle"醬料罐來說完全沒有問題。

Reflection for the behavior dropping the sauce and seasoning. Sometime when you want to drop some of catsup, badly the volume of catsup is too less to make the catsup flew out at once. Then you may rotate the bottle to make the sauce flew down slowly of roughly press it, however, the nice time already was destroyed. It's even not a big problem in our living but we can have a better time.

Convenient for thick sauce whenever how much the volume. When the volume of catsup is much, than open the top cap as usual. When the volume of catsup is a little, than open the bottom cap. Whatever the catchup is more or less, there is no problem with the sauce bottle named "Dual-open Bottle"
