A Chinese company has a new idea to prevent the coronavirus from spreading: Eat your lunch in a paper box.

Food delivery firm Meituan is reportedly giving out a paper “shield” to help customers in China keep germs off their plates in crowded offices or cafeterias.

The shield unfolds into a 20-inch, box-shaped “independent space” that covers the diner’s meal while they eat, reports say. Meituan is providing them to eight restaurant chains to include with deliveries in Beijing and Shanghai in tests that launched this week, the South China Morning Post reported Thursday.

“It can effectively block the possible pollution of droplets when eating in a relatively densely populated area,” Meituan told the outlet in a statement. “With the help of the shields, commuters who return to work can ‘eat alone’ easily.”

The Beijing-based company will also provide medical workers in Wuhan — the epicenter of the coronavirus outbreak — with free protective covers, for which Meituan has applied for two national patents, according to CNBC.

The coronavirus outbreak has reportedly taken a toll on China’s food delivery companies as it has disrupted the country’s economy and sickened more than 80,000 people there. Many people in China continue to work from home and businesses have not fully reopened, CNBC reported.

China’s food delivery apps had some 30 million daily active users prior to the late January Lunar New Year holiday, a number that has fallen by half during the course of the pandemic, according to the South China Morning Post.
