Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container in which a plug body is mounted on a liquid container body so as to be opened and closed directly from the outside.

[0002]

2. Description of the Related Art In a conventional liquid container, particularly a pump injection type liquid container, a large lid having an outer diameter equal to the outer diameter of the liquid container main body is covered on the upper part of the liquid container main body. However, with such a large lid, there is a problem that it becomes difficult to handle it when opening and closing it.In recent years, a small-diameter plug that opens and closes the liquid supply port of the liquid container body is directly opened and closed from the outside. A liquid container without a lid has been proposed.

As an example of this liquid container without a lid (pump injection type liquid container), one shown in FIG. 4 is known (Japanese Utility Model Publication No. 56-13873). In this known liquid container, the plug body 10 that opens and closes the liquid supply port 115 is used.
2 is formed to have a diameter considerably smaller than the outer diameter of the liquid container body 101, and the plug body 102 is detachably attached to the liquid container body 101, and the plug body 102 is attached to the chain line 10.
As shown by 2 ', the liquid supply port 11
5 can be opened. When cleaning the inside of the liquid container main body or when discharging the residual liquid, it is easier to perform the work when the stopper 102 is separated from the liquid container main body 101.

[0004]

However, in the known liquid container shown in FIG. 4, since the stopper 102 is formed to have a relatively small diameter, there is an advantage that the opening / closing operation of the stopper is simple, but the liquid is There was a problem that the stopper 102 had to be pulled out and separated from the liquid container body 101 each time the stopper 102 was replenished, and a place for placing the separated stopper 102 was necessary. Moreover, in the liquid container of FIG.
The inner peripheral surface of the plug hole into which is fitted is formed in a circular shape over the entire circumference.With such a shape of the plug hole, when the liquid container is inclined downward and the residual liquid is discharged, the opening is opened. The liquid comes to flow out from a place with a wide angle range of the part, and there is a possibility that the discharged liquid may wet an unexpected place.

In view of the above-mentioned problems of the known liquid container, the present invention is a liquid container in which the plug can be opened and closed directly from the outside, and the plug is held in the liquid container main body in an open posture during liquid replenishment. It is possible to perform the work as it is, and to make it possible to separate the stopper from the liquid container main body when cleaning or discharging the residual liquid, and
When the residual liquid is discharged, the liquid can be discharged only from a place in the small angle range on the outlet side of the upper opening (plug hole), and further, the plug arc rotating operation and the plug separating operation can be easily performed. That is the purpose.

[0006]

In the liquid container of the present invention, an annular outer peripheral portion having a predetermined width is formed on the upper surface of the liquid container main body, and a plug hole into which a plug is fitted is formed in the annular outer peripheral portion. The body is pivotally attached to the liquid container body so as to be freely pivotable by a hinge device on the rear side which is the opposite pouring side, while being locked by a stopper locking device on the front side which is the pouring side, The front projection of the front part of the plug body is formed so as to project forward, while the annular outer peripheral part is formed with a front recessed part into which the front projection is fitted. Each of which has a groove serving as a bearing formed in a frontwardly inclined state at a predetermined angle, and a pair of left and right shafts that can be removably fitted into each groove. Left and right sides of the front protrusion can be unlocked from left and right Provided work button, and the stopper member in the unlocking state of the lock release operating button characterized in that provided as capable of arc rotation.

[0007]

According to the liquid container of the present invention, since the stopper is pivotally attached to the liquid container main body so as to be detachable and can be rotated and opened and closed in an arc, the stopper is still attached to the liquid container main body. While it is possible to open and close the arc, the plug body can be separated from the liquid container body. Further, the plug hole of the liquid container body is formed in an annular outer peripheral portion having a predetermined width and has a small inner diameter, and the plug body fitted in the plug hole has a small outer diameter. Therefore, the plug body can be easily held when opening or closing the plug body or when attaching or detaching the plug body. Furthermore, if both lock release operation buttons of the stopper lock device that locks the stopper body are pinched from the left and right, the stopper body can be unlocked, and at the same time, the stopper body can be grasped by the fingers pinching the both lock release operation buttons, It is possible to continuously perform the arc rotation opening operation of the plug body or the plug body separation operation in the plug body open posture while the plug lock release operation is performed. In that case, since both lock release operation buttons are provided on both left and right sides of the front protrusion formed on the plug, the front protrusion is left and right in the plug lock released state (a state in which both lock release operation buttons are pinched). It can be firmly gripped from both sides, and thereby the gripping state of the plug body becomes stable. Further, when the residual liquid in the liquid container is discharged, if the liquid container is provided on the front side (pouring side), the discharged liquid will flow out while being guided by the front recessed portion provided on the annular outer peripheral portion. Therefore, the residual liquid can be discharged only from a place in the small angle range on the pouring side. In particular, since the front recessed portion is formed on the side facing the hinge device, even when the liquid container is tilted to the front side while the stopper is still connected by the hinge device when discharging the residual liquid, The discharge action from the small angle range can be achieved.

[0008]

The liquid container of the present invention has the following effects.

(1) Since the arc can be rotated and opened while the plug is attached to the liquid container main body, there is no need to worry about where to place the plug when replenishing the liquid, and the plug is pivotally mounted in such a manner. Since the stopper can be separated from the main body of the liquid container even if it has been used, if the stopper is separated from the main body of the liquid container at the time of discharging the residual liquid or cleaning, those operations (residual liquid discharging work) , Cleaning work) can be easily performed.

(2) Since the plug has a small diameter,
It becomes easy to handle the arc rotation opening / closing operation or the attaching / detaching operation.

(3) Since the stopper can be pinched at the same time as the stopper lock releasing operation, the stopper pivot unlocking operation and the stopper separating operation can be performed continuously with the stopper lock releasing operation. It will be easy.

(4) On the front side (pouring side) of the annular outer peripheral portion,
Since the front recessed portion into which the front protruding portion of the stopper is fitted is formed, when the residual liquid is discharged into the liquid container, by tilting the liquid container to the front side, the discharged liquid is discharged into the front recessed portion. It is possible to allow the residual liquid to be discharged while being guided by, and the residual liquid can be discharged only from a place in the small angle range on the spouting side, and the trouble of wetting an unexpected place with the discharged liquid can be solved in advance.

(5) Especially, since the front recessed portion is formed on the side of the annular outer peripheral portion facing the hinge device,
Even when the residual liquid discharging operation is performed while the stoppers are connected by the hinge device, the discharging action from the small angle range described above can be achieved.

(6) Since both lock release operation buttons of the stopper lock device are provided on both left and right sides of the front protrusion formed on the stopper body, the stopper lock release state (the state in which both lock release operation buttons are pinched) In the above, the front protrusion can be firmly gripped from both left and right sides, and thereby the plug can be gripped in a stable state.
