Description

TECHNICAL FIELD The present invention relates to a mask that covers a person's mouth. More particularly, it relates to a mouth opening/closing type mask improved so that the mouth portion can be opened and closed when eating and drinking.

From 2020 to 2021, the “new coronavirus infection” (WHO name “COVID-19”) was prevalent. Wearing a mask is recommended as a measure to prevent infection with this new coronavirus infection. Even at dinners where multiple people gather to eat and drink, it is recommended to wear a mask except when putting food in the mouth (Prime Minister Kan advocated on November 18, 2020, "Mask dinner").

However, many people do not wear a mask while eating because it is troublesome to wear a mask while eating and to remove or shift the mask every time they bring food to their mouth. In particular, it is troublesome to put on and take off the entire mask including the ear hooks. As a result, the actual situation is that people do not wear masks when eating and drinking, and the prevention of splashes caused by conversation during eating and drinking is insufficient.

Patent Literature 1 below discloses “a mask that can keep the skin moisturized and breathe easily without impairing the original functions of the mask”. However, the mask of this Patent Document 1 does not address the problem of facilitating "mask dinner", and does not have the configuration and action for that purpose.
