Engage the upper surface.

Reference numeral 50 denotes an outer peripheral wall of the press-down head 25.
5a and the upper part of the cylindrical tube 39 are suspended. The outer surface of the lower end portion of the outer peripheral wall 50 is formed in the large outer diameter portion 51 via a tapered portion having a large diameter below.

Reference numeral 60 denotes an elastically deformable seal cylinder made of a soft material. The small-diameter cylinder portion 61 is fitted to the inner surface of the large-diameter portion 51 in an unextractable and water-tight manner through an uneven engagement means.
From the lower end of the small-diameter tube portion 61, a large-diameter tube portion 63 is vertically suspended via an outwardly curved outward flange-like wall portion 62, and the lower end of the large-diameter tube portion is engaged with the upper portion of the mounting tube 15. Engage via the joint.

The engaging portion is formed by a fitting tube 15a rising from the upper surface of the outer peripheral portion of the inward flange-like top plate 16, and the lower end of the seal tube 60 is formed on the outer surface of the fitting tube. Fit. A plurality of first communication passages 64 and a plurality of second communication passages 15b are formed in the seal cylinder 60 and the fitting cylinder 15a, respectively, so that the two communication paths communicate with each other. It is preferable that an outward flange 65 be provided on the outer surface of the lower end of the seal cylinder 60 as described in claim 3.
The communication passage 64 is formed radially on the lower surface of the outward flange.
In the above description, the seal cylinder 60 is fitted to the fitting cylinder 15a. However, the present invention is not limited to this, and the seal cylinder 60 may be fitted to the upper outer surface of the mounting cylinder 15.

Further, the guide tube 15c is erected from the inner peripheral edge of the inward flange-like top plate. When water enters the guide cylinder from the first and second communication passages 64 and 15b, the water does not enter the large-diameter cylinder 3 from the gap between the flange hole of the inward flange-like top plate 16 and the cylindrical pipe 39. The upper end of the seal cylinder 60
In the small-diameter cylindrical portion 61. Note that a ventilation gap through which air can flow is formed between the inner surface of the guide cylinder 15c and the outer surface of the cylindrical tube 39. Further, the guide tube 15c and the small-diameter tube portion 6
1 so that a small-diameter cylindrical portion 61 is formed.
When it is elastically deformed downward, it does not interfere with the guide cylinder 15c.

Further, the mounting cylinder 15 may be provided as described in claim 3.
The outer periphery of the lower part of the mounting cylinder is surrounded by a large-diameter ring 15e via a plurality of connecting pieces 15d projecting from the lower outer surface of the mounting cylinder. Reference numeral 70 denotes a cover member according to claim 3, wherein a drum-shaped cylinder 72 having an opening at the top is erected from an upper part of the cylindrical part which is unremovably fitted to the outer surface of the large-diameter ring 15e through an uneven engagement means. Then, the seal cylinder 6 below the small-diameter cylinder portion 61 in the drum-shaped cylinder
Surround the 0 part. Also, a plurality of triangular engaging plates 73 are protruded from the inner surface of the drum-shaped cylinder 72, and the lower surfaces of these engaging plates are engaged with the upper surface of the outward flange 65 of the sealing cylinder. It is made to approach the outer surface of the large-diameter cylindrical portion 63.

Reference numeral 80 denotes a cap. The lower end of the peripheral wall 81 hanging from the outer periphery of the top plate is detachably fitted to the outer surface of the cover member 70, and the lower end of the peripheral wall is placed on the upward step 71.

Although the present invention has been described above with reference to an example in which the present invention is applied to a bubble jet container having a small-diameter cylinder 23 for jetting liquid, a large-diameter cylinder 3 for air compression, and a mixing chamber 33 for liquid and air. It is needless to say that the present invention can be applied to a liquid ejection container having no large-diameter cylinder 3 for air compression.

Next, the operation of the present embodiment will be described.
Since the sealing cylinder 60 is formed of a soft elastically deformable material, the pressing head 25 can be pressed down. When the cap 80 is removed and the pressing head is pressed down, the upper part of the sealing cylinder is elastically lowered inward. Deform. Conversely, when the pressing head is raised, the seal cylinder 60 returns to the original shape.
Since such a seal cylinder 60 covers the ventilation gap between the guide cylinder 15c and the cylinder tube 39, the infiltration of shower water into the ventilation gap is prevented. On the other hand, the pressing head outer peripheral wall 5
The shower water that has entered the bar member 70 from the gap between the outer surface of the lower end of the cover member 70 and the inner surface of the top opening of the cover member 70 flows out of the cover member 70 through between the connecting pieces 15d of the large-diameter ring 15e.

After the bubbles and the like are ejected, when the press-down head 25 rises and the inside of the container becomes negative pressure, outside air flows in from the lower end between the cover member 70 and the mounting cylinder 15 and the connecting piece 1 of the large-diameter ring.
From between 5d, through the first and second communication passages 64 and 15d, enter the ventilation gap between the guide cylinder 15c and the cylinder tube 39, and further flow into the container body 1 from the large-diameter cylinder 3 through the outside air suction hole 10. I do. When the cover member 70 is not used, the shower water may flow into the seal cylinder 60 from the first and second communication passages 64 and 15b. However, since the guide cylinder 15c is provided, the shower water enters the container body. Is prevented.

[0029]

According to the first to third aspects of the present invention, since the sealing cylinder hangs down from the outer peripheral wall of the press-down head, permeation of shower water or the like into the container body is prevented. According to the second aspect of the present invention, since the communication passage for introducing outside air is formed in the seal cylinder,
With a simple configuration, the introduction of outside air into the container when the container is negatively pressured is ensured. In addition, since the guide cylinder is provided, even when the cover member is not used, infiltration of water into the container body is prevented. According to the third aspect of the present invention, since the cover member is provided, the appearance is improved, and the engagement member is formed on the cover cylinder.
