Description

  The present invention relates to a beverage container having a straw function.

  Beverages that are poured into beverage containers such as beverage cups are generally drunk using straws. However, general straws are made of plastic (resin), and after drinking beverages with straws sold at convenience stores, they are thrown away into trash cans, and are also used for household and many restaurants. Since it is also disposable, it costs money as a plastic waste disposal and is not friendly to environmental problems.

  In recent years, it has been a problem that marine life eats plastic trash and has a big impact on the ecosystem, but those who have visited the sea by swimming etc. throw away the drinking straw to the coast as it is. Or the inflow from rivers, etc., contributes to the generation of plastic waste.

  Against this background, there is a movement to ban the use of plastic straws in the United States, Taiwan, and the United Kingdom, and these efforts are accelerating all over the world. However, as an alternative to plastic straws, This is a change to eco-friendly materials such as bamboo and bamboo, and does not eliminate the straw itself.

  Conventionally, a combination of a mudler and a straw has been proposed (Patent Document 1). However, since this is also disposable, it does not help solve environmental problems. In addition, a food storage container is known in which rice is stored in an inner container of a double container, soup is stored in an outer container, and a vertical hole is formed between the outer container and the inner container (Patent Document 2). Since the hole is a hole for inserting a straw, the use of a straw is merely a premise.
