Description

  The present invention relates to a beverage container.

Conventionally, as a stopper for beverage containers of this type are known, such as the following.

  In a stopper for a beverage container (for example, Patent Document 1), a vent hole is vertically closed with a lid, and the lid is held in a closed state by a lock structure.

  However, when the closure of the beverage container is operated to release the lid closed state by operating the lock member (lock button), the closure of the straw (drink part) and the closure of the vent hole are released almost simultaneously, The internal pressure is released from both the vent hole and the straw, which may cause the liquid beverage to blow out of the straw. In addition, since the air vent is open when the lid is opened, there is a possibility that the liquid beverage leaks from the air vent when it falls.

  Next, in a beverage container with a straw (for example, Patent Document 2), a lid (straw cap) is opened after a vent hole is opened by a lock member, and a liquid beverage is sucked by a straw. Since it is necessary to operate the lock member after closing, the operation is troublesome. Further, when the vent is opened by operating the lock member, there is a possibility that the liquid beverage leaks from the vent to the outside when the container falls.

  Further, in the beverage container with a straw, when the stopper is closed with the straw cap closed (straw closed state), and the liquid beverage stays in a part of the straw due to vibration or the like, the blowout due to the increase in internal pressure Although it can be prevented by operating the locking member, there is a risk that the liquid beverage staying in the straw may blow out due to the rise of the liquid level inside the straw when the straw is opened.

  Next, in a beverage container with a straw (for example, Patent Document 3), when the lock member is operated, the lock member applies an external force to the valve body, and the slit provided in the valve body is deformed by the external force to release the internal pressure. When the lid (straw cap) is opened, the lock member is returned to a predetermined position and the valve body is restored, so that the internal pressure is released and the liquid beverage is prevented from leaking out from the slit (vent). Since the slit may leak if it is not very thin, high-precision processing is required. In addition, since there is no mechanism for maintaining the slit in a closed state, the liquid beverage may leak due to an impact such as dropping.

  Next, in a beverage container (for example, Patent Document 4), a rotation base that opens and closes a vent hole is provided inside the hinge, and the rotation base rotates inside the hinge together with the rotation of the lid to release the internal pressure. However, there is a possibility that the rotating base may be worn due to wear during rotation, and the durability remains doubtful. Further, when the lid is open, the vent hole is closed, and if the straw is sucked in this state, the pressure is reduced and the suction cannot be continued. Furthermore, since the pivot base is provided inside the hinge, the hinge becomes large, and there is a secondary problem that hinders downsizing.

  Next, a beverage container (for example, Patent Document 5) has a structure in which a vent is opened and closed by a sliding operation of a lid (food member). However, the operation of the lid is complicated and the operation distance is long, and the operation is troublesome. Further, although the ventilation hole is closed by a sliding operation, there is a possibility that the closing member may be worn due to wear during sliding, and there is a doubt about durability. Furthermore, when the lid is open, the air hole is closed, and if the straw is sucked in this state, the pressure is reduced and the suction cannot be continued.

  Next, the beverage container (for example, Patent Document 6) has a structure in which the vent hole is opened and closed by a sliding operation of a lid (lid plate), but the operation is troublesome because the operation distance of the lid is long. Further, although the ventilation hole is closed by a sliding operation, there is a possibility that the closing member may be worn due to wear during sliding, and there is a doubt about durability.

  Next, a beverage container cap (for example, Patent Document 7) has a structure in which a vent is opened and closed by a sliding operation of the lid. However, the operation of the lid is complicated and the operation distance is long, and the operation is troublesome. Further, although the ventilation hole is closed by a sliding operation, there is a possibility that the closing member may be worn due to wear during sliding, and there is a doubt about durability. Further, when the lid is open, the vent hole is closed, and if the straw is sucked in this state, the pressure is reduced and the suction cannot be continued.
