Description

[Detailed description of the invention] The present invention relates to the structure of a cartridge type liquid container.

Cartridge-type liquid containers are required to be easy to attach and detach from the device, and to ensure that there is no spillage of liquid when attaching and detaching, and to ensure that the liquid is securely attached to the device when in use, so that the liquid flows out smoothly, and when stored. It is required that there is no liquid leakage, etc., that it has a necessary and sufficient capacity, and that it is inexpensive. For example, although an ink cartridge for a fountain pen satisfies each of the above conditions to some extent, it cannot be used as a large-capacity cartridge due to its small capacity. In case of large capacity,
There is a drawback that the attachment is insufficient, and that if it is removed while the liquid remains, the liquid will leak.

Furthermore, it is well known that oil heater cartridges tend to leak oil when they are installed or removed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive liquid container that solves the above-mentioned conventional drawbacks and satisfies the above conditions.

The liquid container of the present invention is a cartridge-type liquid container in which the filled liquid can be supplied to the apparatus by attaching the cartridge body filled with the liquid to the apparatus, wherein the cartridge body is rotated in one direction to the apparatus. The shaft part has a threaded part or a fitting part to be attached, and a frame part that opens the liquid outlet of the cartridge body by rotation in the same direction as the above rotation direction and closes the liquid outlet by rotating in the opposite direction to the cartridge body. It is characterized by being screwed onto.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the present invention. In other words, the IJ joint body 1 has a bottom part and a lid part integrally formed, and the bottom center has a mounting part 7 formed with a right-handed thread that is screwed onto the device by clockwise rotation. stands out. A liquid outflow hole 5 is bored through the center of the bottom of the IJ joint body 1. In addition, the lid of the cartridge body 1 has a left-hand thread 3.
A shaft portion 2 having a shape thereon is screwed by a knob 8.

A frame portion 6 that closes the fluid outflow hole 5 by compression is formed at the lower end of the shaft portion 2 in the figure, and when the knob 8 is rotated counterclockwise, the shaft portion 2 moves downward in the figure. It has a structure in which the outflow hole 5 is sealed with the frame part 6. Further, when the knob 8 is rotated clockwise, the shaft portion 2 moves upward and the frame portion 6 opens the outflow hole 5. When the container is removed from the device, the knob 8 is fully rotated counterclockwise and the frame 6 seals the outflow hole 5. Therefore, the liquid 9 will not leak out.

Next, when attaching this container to the device, as shown in Fig. 2(a), screw the attachment part 7 into the threaded part (right-handed thread) 1o on the attached side drilled in the device. .

This is done by rotating the knob 8 clockwise as shown. When the knob 8 is rotated clockwise, the cartridge main body 1 rotates together with the knob 8, and the mounting part 7 is screwed onto the threaded part 1o and is mounted on the device as shown in FIG. . When the knob 8 is further rotated clockwise from this state, the shaft portion 2 moves upward in the figure, the frame portion 6 is separated from the outflow hole 5, and the outflow hole 5 is opened. That is, the internal liquid smoothly flows out into the device through the outflow hole 5. When removing the container, rotate the knob 8 counterclockwise to lower the shaft 2 and close the frame 6 to the outflow hole 5, and then rotate the knob 8 counterclockwise to loosen the mounting part 7. It separates from the threaded part 10 at . At this time, since the frame portion 6 seals the outflow hole 5, no liquid will leak out. This embodiment has the advantage that it has a simple structure, can be provided at low cost, can be easily attached to and detached from the device, and does not cause liquid leakage. Further, the container can be of any size and can be filled with the necessary and sufficient amount of liquid.

The screwing of the shaft portion 2 to the cartridge body 1 is shown in Fig. 3(a).
The knob 8 and the lid may be screwed together as shown in FIG.
Alternatively, as shown in FIG. 2B, a left-hand thread (male) provided on the inner periphery of the outer edge of the knob 8 may be screwed into a left-hand thread (male) on the upper outer periphery of the cartridge body 1. The cartridge main body can be attached to the device by screwing a female screw drilled in the center of the bottom of the cartridge main body 1 into a male screw on the device side as shown in FIG. ), a male thread may be formed on the outer periphery of the lower part of the cartridge body 1, and the structure may be such that it is screwed into a large diameter female thread on the device side. Alternatively, as shown in FIG. 3(d), instead of a screw, it is a mounting part 7' that is simply fitted into the device (5), so that when the cartridge body 1 rotates, the bottom surface of the cartridge body 1 is brought into contact with the top surface of the device. It may also be a structure in which grooves or protrusions are formed to allow close contact. Furthermore, the frame portion that opens and closes the liquid outflow hole 5 has a structure that closes the outflow hole 5 according to the position of a groove parallel to the axial direction formed at the tip of the shaft portion 2, as shown in FIG. It's okay.

FIG. 4(a) shows the state where the outflow hole 5 is closed, and FIG.
) shows the state in which the outflow hole 5 is opened. In short, the shaft part 2
Any structure is sufficient as long as the outflow hole can be opened and closed by the rotation of the valve, and various modifications other than those described above are conceivable.

As described above, in the present invention, the cartridge body has a threaded part or a fitting part that is attached to the device by rotating in a certain direction, and an outflow hole is opened by rotating in the same direction as described above, and the outflow hole is opened in the opposite direction. Since the structure is such that the shaft is screwed onto the cartridge main body, which has a frame that closes the outflow hole by rotating the shaft, the outflow hole can be opened after the cartridge main body is installed in the device by rotating the shaft in one direction. After opening has taken place and the outlet (6) has been closed by rotation in the opposite direction, the IJ joint body is removed from the device. Therefore, it is possible to easily attach and detach the cartridge to and from the device, and there is an effect that liquid leakage does not occur.

The container of the present invention has a simple structure, can be provided at low cost, and can be of any size.
