Threadless vertical lid-opening structure for containers

A container with a threadless vertical lid-opening structure, comprising

• a container body,
• a lid body,
• a sealing device, wherein the sealing device is arranged on the lid body and comprises a base and a deformable elastic sealing element sleeved on the base,
• wherein the lid body is sealably arranged on the container body through the sealing device;
• the base is provided with a pulling shaft, the lid body is provided with a latch switch, the latch switch and the pulling shaft are connected through a rotating member, a guiding face is arranged inside the lid body, the rotating member and the guiding face abut against each other to rotate, an opening is formed on the guiding face, one end of the pulling shaft penetrates through the opening and is connected to the rotating member, the other end of the pulling shaft is connected to the base, and when the latch switch rotates, the rotating member is driven to rotate, and the rotating member causes the pulling shaft and the base to axially move upward or downward;
• the lid body is further provided with a limiting block, and the limiting block limits flipping of the latch switch with an optimal effect;
• and
• when the base connected to the pulling shaft moves upward, the deformable elastic sealing element expands radially and bends outward to be snap-fitted with a snap-fit opening of an inner wall of the container body, thereby achieving sealed engagement between the lid body and the container body;
• and when the base connected to the pulling shaft moves downward, the deformable elastic sealing element retracts and disengages from the inner wall of the container body, thereby achieving disengagement between the lid body and the container body.
