Description

The present invention relates to a lid lock structure for a beverage container, and more particularly to a lid lock structure useful for various beverage containers such as a water bottle and a portable thermos bottle.

Conventionally, various lid lock structures have been proposed in order to prevent the lid of the beverage container from opening unexpectedly. For example, a spout member attached to the upper opening of the container body and a lid member that is hingedly connected to the spout member and airtightly covers an extraction port that opens to the top plate of the spout member. In the stopper body of the beverage container provided with a lock mechanism for holding and releasing the closed state of the lid member on the side opposite to the hinge, the lock mechanism is provided at the rotating end of the lid member. A lock button pivotally supported by an engaging piece and a shaft member provided on the outer surface of the spout member and rotatably attached in the inward and outward directions of the spout member, and slidable on the outer peripheral wall of the spout member. The lock button is provided with a sliding stopper, and the lock button has an engaging portion on which the engaging piece can be engaged and disengaged, and the engaging portion is urged in the engaging direction with the locking piece. The sliding stopper is a stopper piece that regulates the movement of the lock button in the unlocking direction when the sliding stopper is inserted between the lower portion of the lock button and the outer peripheral wall of the spout member. And, there is known a stopper body of a beverage container characterized by having a locking portion for holding the sliding stopper at an insertion position and a non-insertion position of the stopper piece. 1). In the present invention, the sliding stopper is slid vertically with respect to the spout member of the beverage container, and the stopper piece is inserted between the lower part of the lock button and the outer peripheral wall of the spout member to lock the lock. It regulates the unlocking of buttons. However, in the present invention, when the slide-type stopper is lowered, a gap is formed between the lock button and the slide-type stopper, so that foreign matter may enter the gap. If the sliding stopper is raised without knowing it, the operation of the sliding stopper may be hindered. In addition, if the slide stopper is accidentally raised to a position that restricts the operation of the lock button with the lid member open, and the lid is closed in that state, an excessive load is applied to the lock button and its shaft portion. There was also the problem that it would be damaged.

In order to solve such a problem, for example, a lid lock structure that holds a lid pivotally attached on the main body in a closed state by locking with a locking claw of a locking member pivotally attached to the main body. Inside the locking member, the sliding lock member that slides along the locking member in the length direction thereof, and the sliding lock member and / or the locking member are urged outward. The sliding lock member includes an operating portion that projects to a position outside the outer surface of the locking member, and a locking member when the operating portion is pressed inward and rotated. When the sliding lock member is slid to one side in the length direction of the locking member and the rotational force transmitting portion that rotates the locking claw in the unlocking direction, the main body member A lid lock structure has been proposed in which a rotation restricting portion for preventing the rotation of the sliding lock member is formed in contact with or close to a part of the sliding lock member (Patent Document 2).

INDUSTRIAL APPLICABILITY The present invention can easily open and close the lid, prevent the lid from opening unintentionally, and reliably prevent the lid lock member from operating. It provides a lid lock structure for a beverage container, which can be manufactured at a remarkably low cost, in addition to having a structure that can be formed and hardly damages the lid lock member.

According to the invention described in Patent Document 2, various problems in the invention described in Patent Document 1 can be solved. However, in the lid lock structure described in Patent Document 2, since the structure is complicated, an increase in manufacturing cost cannot be avoided. Therefore, the present inventor has attempted various studies on how to solve the above problems without increasing the manufacturing cost. In the invention described in Patent Document 1, it is the operating portion of the slide-type stopper that a foreign substance enters the gap between the lock button and the slide-type stopper when the slide-type stopper is moved up and down and hinders the operation of the slide-type stopper. It was thought that this is because foreign matter may adhere to the vicinity of the operation part and get caught in it because it protrudes outward and slides up and down. In addition, since the operating part of the sliding stopper is the lower part of the lock mechanism and is attached to the spout member, it is difficult to recognize the presence of foreign matter at first glance when the lid member is changed from the open state to the closed state. I thought it was for. Therefore, if the operation part of the slide type stopper is installed at a position where it is easier to see, not only can the problem of foreign matter being caught in the slide type stopper be solved, but also the position of the stopper can be easily confirmed, and the lock part can be set.
