Dosirac

Dosirac (도시락, Доширак) is a brand of cup ramyeon produced by Paldo in South Korea since 1986. The brand is sold in 30 countries and annual sales exceed $1.5 billion.

The literal translation of 도시락 means lunchbox.

Since being introduced to the market in the 1990s, Dosirac has become one of the most popular brands of instant noodles in Russia and Central Asian nations such as Kazakhstan and Uzbekistan, albeit slightly rebranded as Doshirac ("Доширак" in Cyrillic). It was first introduced to Russians through sellers who visited Korea via the port of Busan. To facilitate its growing popularity in the country, Paldo had opened a subsidiary in Russia in 2002. It makes up over 60% of the instant noodle market in Russia and its immense popularity has led people in the country to refer to all instant noodles as Doshirac. In June 2019, Paldo applied to register Doshirac as a trademark with Russia's patent office; after being rejected, the application sparked a court case that Paldo eventually won in 2021.

As for 2010s, Доширак brand name is also used for the simplified (no-box) instant noodles, initially known as "Kvisti" - a smaller (70g e.g. 2,3 oz) brick of instant noodles the similar texture and the similar spices. The cup-less "Doshirac Kvisti" packet is only the third of the price of the "classic" box of Doshirac.

A rival's reaction
Rollton (another instant noodles brand in ex-USSR) answered to Dos(h)irac's success by making a similar-sized 90g "brick" of instant noodles that could match the dimensions of Doshirac's rectangular cups, so a Doshirak consumer could reuse the cup for cheap.
