Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an inclined liquid injection type in which a handle can be grasped to incline a liquid container, and the liquid can be injected through an injection passage in a stopper body in a plugged state. The present invention relates to a liquid container adapted to be able to do so.

[0002]

2. Description of the Related Art Known liquid containers of this type include, for example, those disclosed in JP-B-59-25332 or JP-B-62-37543. In these known liquid containers, an operation button is provided on the upper part of the handle for tilting the liquid container, the valve body inside the stopper is opened by pressing the operation button, and the handle is gripped and tilted to move the inside of the inner container. The liquid can be poured to the outside through the injection passage in the stopper.

In the liquid container disclosed in Japanese Utility Model Publication No. 59-25332, the valve element can be opened via the valve element operating member provided in the stopper body by pressing the operation button on the handle. However, when the finger is released from the operation button, the valve element is immediately closed by the biasing action of the spring. Incidentally, the third in the publication
In the liquid container shown in FIG. 4 and FIG. 4, by pressing the operation button, the valve body can be opened via the valve body operating member, and at the same time, the flap for opening and closing the inlet can be opened. However, when the finger is released from the operation button, the valve body and the flap are immediately closed.

On the other hand, in the liquid container of Japanese Utility Model Publication No. 62-37543, a valve body position holding mechanism (called a push-push mechanism) is provided on the shoulder of the liquid container body.
Each time the operation button on the upper part of the handle is pressed once, the valve body can be alternately held in the open position or the closed position, but the operation button is biased outward by the spring. When the finger is released from the operation button, the operation button is automatically returned to the outer fixed position.

[0005]

However, in the liquid container disclosed in Japanese Utility Model Publication No. 59-25332, the valve body is automatically closed when the finger is released from the operation button. There is a problem that it is necessary to tilt the liquid container main body while pressing the operation button, and the liquid injection operation must be performed in an unnatural state (the operation button is pressed).

Further, in the liquid container of Japanese Utility Model Publication No. 62-37543, the valve body position holding mechanism (push-push mechanism) allows the valve body inside the stopper body to be held at the open position and the closed position. However, when you release your finger from the operation button, the operation button automatically returns to the outside fixed position, and from the appearance it is possible to know whether the valve body is in the valve closing position or the valve opening position. There was a problem that I could not. When not injecting the liquid, if the valve body is left open and not noticed, the heat retention will decrease and the liquid in the inner container will be injected into the stopper when the liquid container is tumbled. There is a problem that it flows out to the outside through the liquid passage, and during the liquid injection operation, even if the liquid injection operation (tilt the liquid container) is performed without noticing that the valve element is in the closed state, It is not possible, and it is necessary to perform the liquid injection operation again after performing the valve opening operation.

In order to address the above-mentioned problems, the applicant of the present invention has disclosed, as Japanese Patent Application No. 4-48097, a liquid container in which a valve element inside a stopper can be opened and closed by an operation button provided on an upper portion of a handle. In the above, it is proposed that the liquid injection operation can be performed with the finger released from the operation button, and that the open / closed state of the valve body can be known from the outside even with the finger released from the operation button. However, in the case of this prior application example, a valve body for simultaneously opening and closing the valve body and the flap,
Since the flap operating member is arranged on the plug side and the flap is arranged on the liquid container body side, when the valve body and the flap are opened, the operating body of the valve body / flap operating member is on the liquid container body side. The state of being projected from the opening (facing the rear end portion of the flap) formed in is retained. In such a state, if a user who is not familiar with the structure of this type of liquid container inadvertently unscrews the stopper, the operating end of the valve body / flap operating member engages with the opening edge. May be damaged.

The present invention has been made in view of the above points, and when the valve body and the flap operation member are accidentally screwed out while the valve body and the flap are in the open operation, The purpose is to prevent the operation end and the opening on the liquid container body side from engaging with each other.

[0009]

Means for Solving the Problems In the present invention, as means for solving the above-mentioned problems, a plug body that can be screwed into and removed from a liquid container body, a handle for lifting the liquid container body, and the liquid A flap provided on the container body for opening and closing a pouring port, a liquid injection passage communicating with the pouring port, a valve body for opening and closing the liquid pouring passage, the valve body and the flap. A valve element / flap operating member for simultaneously opening and closing the valve is provided, while an operating button for the valve element / flap operating member is provided at an upper position of the handle, and the valve element / flap operating member is opened or closed. In a liquid container provided with a valve body / flap position holding mechanism for holding the valve body / flap position member in the side position, the operation end of the valve body / flap operation member is connected to the open side of the valve body / flap operation member. It is composed of a rod-shaped body that protrudes to a position where the rear end of the flap should be pressed through an opening formed on the liquid container body side when moving, and the opening edge is the screw unthreading direction of the plug body. An inclined guide surface is formed on the side on which the operation end engages when it is turned to, to promote the disengagement of the operation end from the opening.

[0010]

In the present invention, the following actions can be obtained by the above means.

That is, the valve body and the flap operating member simultaneously open the valve body and the flap (that is,
(The operation end of the valve body / flap operating member is projected into the liquid container body through the opening), and someone who is not familiar with the structure of the liquid container accidentally tried to unscrew the plug body. Also in this case, the operation end of the valve body / flap operation member is guided by the inclined guide surface formed at the opening edge and easily separated from the opening.

[0012]

According to the present invention, the valve body and the flap operating member simultaneously open and close the valve body and the flap, and the valve body and the flap position holding mechanism act to open or close the valve body and the flap operating member. In a liquid container configured to be held at a closed side position, the operating end of the valve body / flap operating member is formed on the liquid container body side when the valve body / flap operating member is operated to the open side. The flap is formed of a rod-like body that projects through the opening to the position where the rear end of the flap is to be pressed, and the operation end is engaged when the stopper body is rotated in the screwing-out direction. On the side, an inclined guide surface that promotes the separation of the operating end from the opening is formed, and the valve body and the flap operating member simultaneously open the valve body and the flap (that is, the valve body
Even if a person who is not familiar with the structure of the liquid container accidentally tries to unscrew the stopper when the operating end of the flap operating member is projected into the liquid container main body through the opening) Since the operating end of the valve body / flap operating member is guided by the inclined guide surface formed on the opening rim so that it can be easily separated from the opening, the operating end of the valve body / flap operating member is damaged. There is no fear, and there is an excellent effect that screw rotation of the stopper can always be performed safely.
