DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container mounted on a liquid container main body so that a plug can 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 the same outer diameter as the outer diameter of the liquid container main body is covered on the upper portion of the liquid container main body. However, with such a large lid, there is a problem that it is difficult to handle the opening and closing operation. In recent years, a small-diameter plug for opening and closing 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.

FIG. 4 shows an example of such a liquid container without a lid (pump injection type liquid container) (Japanese Utility Model Publication No. 56-13873). In this known liquid container, the plug 10 for opening and closing the liquid supply port 115 is provided.
Numeral 2 is formed to be considerably smaller in diameter than the outer diameter of the liquid container main body 101, and the outer shape of the plug 102 and the plug hole on the liquid container main body 101 side are each formed in a circular shape without unevenness. Further, in this liquid container, the lock release operation buttons 161a and 161a of the stopper lock device are provided on the upper surface portion of the stopper 102, and both the lock release operation buttons 161a and 161a are provided.
The liquid supply port 115 can be opened by pulling out the plug 102 upward as indicated by a chain line 102 'with the 161a pinched from the left and right.

[0004]

However, the known liquid container shown in FIG. 4 has the following problems.

That is, a circular plug 102 having no irregularities in its outer shape.
The lock member of the stopper lock device (lock release operation button 1)
61a, 161a) are provided.
When the lock member is provided in the main portion (in the circular portion) of No. 02,
Since a space for installing the lock member is required in the plug main body, downsizing of the plug is restricted.

Further, the inner peripheral surface of the plug hole into which the plug 102 is fitted is formed in a circular shape over the entire circumference, and in such a plug hole, the liquid container is inclined downward and the liquid container is left. When the liquid is discharged, the liquid flows out from a wide angle range of the opening, and there is a possibility that the discharged liquid may wet an unexpected place.

[0007] In view of the above-mentioned problems of the known liquid container, the present invention can achieve further miniaturization of the plug, and furthermore, at the time of discharging the residual liquid, the location of the upper opening (plug hole) with a small angle range on the discharge side at the upper opening (plug hole). It is an object of the present invention to allow the liquid to be discharged only from the container and prevent the stopper lock device from being inadvertently unlocked when the liquid container falls.

[0008]

According to the liquid container of the present invention, the top surface of the liquid container main body is formed by a shoulder member forming a shoulder of the liquid container main body, and a plug is fitted into the shoulder member. ,
On the rear side, which is the anti-pouring side, the hinge is pivotally openable and closable with respect to the liquid container body, while the front side, which is the discharging side, is locked with a plug lock device, and the front side of the plug body is locked. The front locking portion is formed on the left and right sides of the front locking portion. An unlock operation button that can be operated is provided,
The lock release operation button is installed so as to fit into the fitting recess in the closed state, and a gap for unlocking the lock release operation button is formed between the lock release operation button and the fitting recess. I have.

[0009]

According to the liquid container of the present invention, the following effects are obtained.

In the liquid container having a structure in which the stopper is fitted into the shoulder member of the liquid container main body, the lock release operation buttons of the stopper locking device are provided on the left and right sides of the front protrusion. A lock release operation button can be provided by utilizing this.

In the closed state, the two unlocking buttons are fitted in the fitting recesses of the shoulder member, so that the unlocking buttons are guarded by the shoulder members. The release operation button does not collide with the external structure and the lock release operation is not carelessly performed.

In particular, when discharging the residual liquid in the liquid container,
When the liquid container is tilted to the front side (pouring side), the discharged liquid flows out while being guided by the fitting recess provided in the shoulder member, and this fitting recess can be used as a passage for the residual liquid treatment. .

[0013]

According to the liquid container of the present invention, the following effects can be obtained.

(1) In the liquid container having a structure in which the plug is fitted into the shoulder member, the lock release operation buttons of the plug locking device are provided on the right and left sides of the front protruding portion. There is no need to provide a plug locking device, and the outer shape of the plug main body can be formed more compact accordingly. When the outer shape of the plug main body is formed compact in this way, the plug opening and closing operation is facilitated.

(2) In the closed state, the two unlocking buttons are fitted into the fitting recesses of the shoulder member, so that the fitting recesses function as a protective cover for the unlocking button, for example, when the liquid container falls down. The problem that the lock release operation button does not collide with the external structure and the lock release operation is performed carelessly and the liquid inside flows out can be solved beforehand.

(3) Since the fitting concave portion is formed on the front side (pouring side) of the shoulder member, when the liquid remaining in the liquid container is discharged, the liquid container is inclined forward to discharge the liquid. The liquid to be discharged can be caused to flow out of a narrow range while being guided by the fitting concave portion, and the trouble of wetting an unexpected place with the discharged liquid can be solved beforehand.

(4) The operation of discharging the residual liquid from the fitting recess can be performed while the plug is attached to the liquid container body in an open position, and the operation of discharging the residual liquid is facilitated.
