The traditional yoghurt cartons have cubic-shaped design. Typically, a layer of yoghurt will cling to the bottom (corners) and sidewalls inside the carton. This thin layer is still tasty and can be enjoyed, but it is difficult to access. The most common way to drink this type of layer is to insert a straw through the lid. This makes it difficult to access the corners and the sidewalls. Usually, people peel off the lid and then scrape off the remaining yoghurt, which is not a convenient approach. The StrawGhurt carton can let people enjoy the remaining yoghurt just by compressing yoghurt carton.
