The structure of the cup is novel, the principle is unique, thecup can be conveniently stored by users, and space is saved; the cleanliness and dryness of the interior and brim of the cup are ensured, and moreover, the dustproof cup has certain ornamental value.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a water cup. Background technique [0002] The water cup is a common item for people to drink water in daily life. In order to ensure the cleanliness of the inside of the water cup, the water cup is often buckled in the cup tray when storing and placing, which can effectively prevent the floating and sinking in the air from sinking into the water cup; but this operation method will make the cup If the mouth of the cup is in contact with the cup, plate or table, a layer of water film will be formed at the position where the mouth of the cup is in contact with the table.

In order to ensure the cleanliness of the inside of the water cup, the water cup is often buckled in the cup tray when storing and placing, which can effectively prevent the floating and sinking in the air from sinking into the water cup; but this operation method will make the cup If the mouth of the cup is in contact with the cup, plate or table, a layer of water film will be formed at the position where the mouth of the cup is in contact with the table. In this humid and unventilated place, bacteria are easy to breed and seriously pollute the mouth of the cup. Therefore, the cup appears normal when it is placed. It is embarrassing to place or invert; therefore, some bars and restaurants choose to hang the cups, but the hanging cups and cup holders occupy a large space, and are prone to collisions and falls, which is always inconvenient for storage
