FIG. 1 is a perspective view showing a state in which a mouth plug of a liquid container according to the present invention is attached to a liquid container.
FIG. 3 is an exploded perspective view of the mouth plug of the liquid container of the present invention, and FIG.
1 is a cross-sectional view of FIG. 1, and FIG. 4 is a perspective view of a state where the lid of FIG. 1 is opened. Hereinafter, description will be made based on these drawings.

In the mouth plug of the liquid container according to the present invention, the cap of the liquid container 1 such as a PET bottle is removed, and the liquid container 1 is attached to the threaded opening 2 instead of the cap. It can be used as follows.

The mouth plug of the liquid container according to the present invention is provided with a mounting portion 3 having a hole capable of projecting a thread groove of the mouth portion 2 of the liquid container 1 and a threaded engagement with the thread groove of the mouth portion 2. Pressing member 4
And a lid 5 for opening and closing the mouth 2, and a handle 6 is provided integrally with the mounting portion 3.

More specifically, the mounting portion 3 has a cylindrical portion 3a for covering the neck of the liquid container 1 and a skirt portion 3b for covering the shoulder of the liquid container 1, and the cylindrical portion 3a has a liquid. A step 3c is provided on the inner peripheral surface for contacting the ring remaining when the cap of the container 1 is removed. Then, the mounting portion 3 is connected to the opening 2 of the liquid container 1.
, The thread groove portion of the mouth 2 of the liquid container 1 projects from the central hole.

The holding member 4 is a cylindrical member having an internal thread formed on the inner peripheral surface thereof to be screwed with the screw groove of the mouth 2 of the liquid container 1, and holds the mounting portion 3 against the liquid container 1. It is for fixing.

The lid 5 comprises a lid main body 5a and a lever 5b extended from the lid main body 5a. The lid main body 5a covers the upper end opening of the holding member 4. 5a
A packing 5c is provided on the inner side surface of the holding member 4 so as to contact the upper end opening of the holding member 4. Further, one end of the lever 5b is an operation unit.
5d, when the operating portion 5c is pressed, the pivoting portion 5e pivotally supported by the handle 6 pivots, the lid body 5a is lifted, and the upper end opening of the holding member 4 is opened. I have. Further, a substantially J-shaped lock claw 5f is slidably mounted near the lid body 5a of the lever 5b.
The lid 5 is locked by sliding the tip 5f forward and engaging the tip with a part of the handle 6.

The lock mechanism for preventing the lid 5 from being opened is not limited to this example, but may be changed to another mechanism.

The handle 6 has an inverted L-shape integrally formed with the mounting portion 3, and has a lock claw engaging hole 6a at a position corresponding to the tip of the lock claw 5f and a shaft support projection 5e. A shaft support hole 6b is formed at a position where the shaft support hole 6b is formed.

The mouth plug of the present invention having the above structure is used as follows.

When the cap of the liquid container 1 is removed and the mounting portion 3 is covered, the screw groove portion of the mouth portion 2 of the liquid container 1 projects from the central hole.

Next, when the holding member 4 is screwed into the screw groove of the mouth portion 2 of the liquid container 1, the mounting portion 3 is firmly fixed to the liquid container 1.

In use, when the operating portion 5d of the lever 5b is pressed, the lid body 5a is raised and the lid is opened, so that the handle 6 is poured with the handle 6.

When not in use, when the lock claw 5f is moved toward the front lid body 5a, the lid is locked and cannot be opened.

The embodiment has been described above. In this embodiment, the mounting portion 3 and the holding member 4 are provided separately, but they may be implemented integrally.

Further, although an example has been shown in which the attachment portion 3 is pressed against the mouth portion 2 of the liquid container 1 for attachment, the attachment portion 3 may be pressed on the shoulder portion of the liquid container 1 for attachment. it can.

Furthermore, the mouth plug of the liquid container of the present invention is attached to the mouth of the liquid container 1 and is not limited to the size of the liquid container 1.
The present invention can be applied to the liquid container 1 of any size from ml to 2000 ml.

[0027]

As described above, in the mouth plug of the liquid container according to the present invention, it is screwed into the screw groove of the mouth 2 of the liquid container 1 and can be securely attached, so that it is easy to use. Become.

The lid 5 for opening and closing the opening 2 can be further opened and closed by turning the lever 5b.

Furthermore, if a lid 5 for opening and closing the opening 2 is provided with a lock mechanism for preventing the lid from opening, the lid will not be opened inadvertently, making it easier to use.
