Description

  The present invention relates to a stopper for a beverage container that can be disassembled.

  Conventionally, the following is known as a structure for improving the cleanability by allowing the stopper of this type of beverage container to be disassembled.

  In the plug structure of a portable container (for example, Patent Document 1), the internal plug (the plug body in Patent Document 1: the same applies hereinafter) and the external plug (plug cover) are fitted by an elastic member (plug cover packing), This elastic member prevents the internal stopper from slipping or falling off, but it cannot reliably prevent the slipping or dropping off. For example, when the lid is closed with the stopper removed from the container body, The stopper will slip or drop off.

  A portable vacuum double bottle (for example, Patent Document 2) and a bottle stopper (for example, Patent Document 3) include an internal plug (internal plug portion) and an external plug (outer plug member), and have no elastic member. Since the internal plug is not securely fitted in the same manner as the above, the internal plug is displaced or dropped when the lid is closed with the plug removed from the container body. In addition, since the lid body has a structure that can be separated and disassembled in Patent Document 2, the number of parts increases, the attachment / detachment operation becomes complicated, and there is a concern that the parts may be lost.

  Moreover, in the thing of patent document 3, since an inner stopper is further comprised by an inner / outer cylinder, the number of parts increases, attachment / detachment operation becomes complicated, and there also exists a possibility of losing parts.

  Moreover, in the stopper (for example, patent document 4) of the container for drinks, since there is only one latching | locking part when there is one latching member, there exists a possibility that a fitting may come off with the force from the upper side, When there are a plurality of locking members, only one locking member may be fitted, and it is necessary to operate with both hands.

  Moreover, in the stopper (for example, patent document 5) of a liquid container, although an internal stopper (lower assembly) is attached or detached from the downward direction of an outer stopper (upper assembly), since there is no appearance change element exposed to an upper outer surface by operation, Confirmation of the attachment / detachment state and the attachment / detachment operation (completion) is difficult from the top viewpoint, and insufficient attachment or attachment failure due to an operation error occurs, causing leakage. In addition, the structure is such that it does not slip or fall off after being securely fitted, but the structure is complex, and the operability when removing the internal plug is not simple and clear.

  In addition, in the heat retaining bottle (for example, Patent Document 6), since the internal plug (inner plug) is attached / detached from above the external plug (outer plug), it is easy to check the attached / detached state and the attaching / detaching operation (completed), but the valve body is separated. Since it cannot be integrated with the plug body, the liquid flow path is not completely opened by parts decomposition, and the cleaning performance is not sufficiently improved by parts decomposition.

  Finally, in a beverage container plug (for example, Patent Document 7), the plug can be washed to every corner by removing the inner plug from the outer plug. Since the locking member supported by the hinge is attached to the inner plug, the internal stopper is inferior in cleaning performance at the locking member portion.

  And as a problem common to patent documents 1-7, since an external stopper is attached to a container main part even if there is no internal stopper, when attaching an external stopper to a container main part in the state which forgot to attach an internal stopper, it is a lid. Leakage occurs without water stopping in the body.

  In addition, it is not preferable that other parts that cannot be disassembled are attached to the internal stopper when the internal stopper that is most easily touched and dirty with beverages is washed.

  Further, since the lid of the beverage container of this type is arranged so that the lid covers the stopper body, if the lid is impacted by a drop impact or the like, the lid hinge shaft is easily loaded, and the lid hinge There is a concern that the shaft may be bent or the lid may be damaged. In addition, the center of gravity of the stopper moves backward when the lid is open. However, in the structure in which the lid covers the stopper body, the lid becomes relatively large so that the independence of the beverage container is stabilized. There is a risk of disappearing.

Japanese Patent No. 3904899 Japanese Patent No. 5157627 JP 2008-239177 A Japanese Patent No. 5236768 Japanese Patent No. 2735091 Japanese Patent No. 5012920 JP 2013-56680 A

In this case, since the click protrusion 90 is engaged with the open position recess 91A and the lid body 12 is held in the open position, the lid body 12 does not close when drinking or pouring, and the lid body 12 is not closed. Will not get in the way. In this case, the urging force of the compression coil spring 87 is set so that the click protrusion 90 does not get over the click portion 92 at least by the dead weight of the lid body 12.

  On the other hand, when the cover body 12 in the closed position is rotated in the closing direction and a predetermined force or more is applied in the closing direction, the click projection 92 can get over the click projection 92. In the state where the lid 12 is opened, the safety stopper 121 is positioned above by the compression coil spring 129 as shown in FIG. This position is a position where the movement of the lock member 16 is not restricted. When the lid body 12 is rotated downward from the position shown in FIG. 6, the rear surface of the connecting portion 112 comes into contact with the plug body engaging portion 101, and the connecting portion 112 is When the lock member 16 is rotated so as to move to the front side and the plug main body engaging portion 101 passes through the connecting portion 112, the lock engaging portion 115 is locked under the plug main body engaging portion 101. Also in this case, similarly to when the lid 12 is opened, the lock member 16 is elastically deformed so that the arm portions 111 and 111 are opened at the time of the passage, and after the passage, the lock member 16 is restored by the elastic restoring force. It is done by one action.

  After the lock engagement portion 115 is locked to the stopper main body engagement portion 101 in this way, the safety stopper 121 is lowered and the claw portion 133 is locked to the downward surface 103, whereby the restriction portion 123 of the safety stopper 121 is locked. It is located in front of the joint portion 115, and this position is a position where the operation of the lock member 16 is restricted by the safety stopper 121. Even if the lock member 16 is touched, the lock is not released. Thus, the safety stopper 121 is held at a position that restricts the operation of the lock member 16 only when the lid 12 is in the closed position. When the lid 12 in the opened position is closed, the safety stopper 121 is held.
