Moreover, because the lip portion 5 d is not a straw type or a tube type, therefore cold and hot drinks are both suitable.
  • the conventional metal spring is being replaced by a non-metal resilient member 14 made of soft synthetic resin or rubber to force the lid body 7 towards an opening direction. Therefore, even when the plug 3 gets wet due to washing, it does not rust and is very hygienic. Additionally, because the resilient member 14 is arranged at the side of the lid body 7 , therefore there is no unnecessary protrusion on the plug body 5 and the user will not knock his nose while he/she drinks. By using this resilient member 14 to block the air hole 12 , the number of assembly parts can be reduced to decrease the manufacture cost. Furthermore, because the resilient member 14 is arranged in a direction vertical to the air hole 12 , the air hole 12 can be firmly blocked.

  • the upper surface 20 a of the lip portion 20 is cut along an angle ⁇ 2 from the line L 5 vertical to the axial line L 4 of the installation ring 5 h and the lip portion 20 .
  • a user can make the upper surface 5 f face along any circumferential direction he/she likes to freely drink the beverage contained inside the container body 2 .
  • the resilient member forcing the lid body towards an opening direction can also be arranged at the side of the plug body.
  • the resilient member blocks the air hole of the plug body.
  • the containers for beverages can also have no air holes. Even if the container has an air hole, it is not limited to use the resilient member to block the air hole.
  • the resilient member is made to be a hollow type, a solid type of a resilient member can also be used to practice the present invention. Additionally, the resilient member can be freely located rather than along the line connecting the hinge and the lock device.
  • the resilient member is made of a non-metal such as soft synthetic resin or rubber replacing the conventional metal spring to force the lid body towards an opening direction, therefore even when the plug is wetted during washing, it will not rust and is very hygienic.
  • the resilient member is arranged at the side of the lid body, there will be no unnecessary protrusion on the plug body, and therefore the user will not knock his/her nose as the user drinks the beverage contained inside the container body 2 .
  • the resilient member is arranged in a direction vertical to the air hole such that the air hole can be firmly blocked.
  • the resilient member can contract and stretch well following the closing and opening of the lid body and therefore it can provide the functions of spring opening of the lid body and also blocking the air hole.
  • the lip portion and the plug body are separately formed, the lip portion is installed on the top plate of the plug body in a way capable of rotating in the circumferential direction. Therefore, the user can turn the upper surface cut into a taper shape to the direction he likes and drink freely.
