[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid ejecting container which can be used both upside down.

[0002]

2. Description of the Related Art As shown in, for example, Japanese Utility Model Publication No. 56-20052,
A liquid ejector for both upright and inverted use is known, but in the conventional one, a main pipe of a three-pronged connecting pipe is fitted to a lower end of a cylinder, and an auxiliary pipe that branches downward and protrudes is provided with a suction pipe for upright use. The lower end of the suction pipe for inverted use is fitted to the upper end of the raising pipe, and the lower end of the suction pipe for inversion is inserted into the auxiliary pipe projecting upward and projecting downward and upward, and into the auxiliary pipe projecting downward. Has a check valve for closing the pipe line when it is inverted and a check valve for closing the pipe line when it is erected in the auxiliary pipe projecting upward.

Accordingly, the two suction pipes, one for the upright and the other for the upside down, have the former hanging downward from the lower end of the cylinder while the latter rising upward, and these are integrated with the cylinder. Therefore, it is inconvenient when inserting and removing the cylinder into and out of the container, and if the container is transparent, the suction pipes can be seen, so that the appearance is impaired.

[0004]

SUMMARY OF THE INVENTION According to the present invention, it is possible to use only one suction pipe.
When the container is erected, the liquid is sucked up through the suction pipe, whereas when the container is inverted, the upper end of the suction pipe is connected to a suction tube or a suspension tube that hangs down from the liquid ejector. A suction port is formed in the portion, and the liquid is sucked into the liquid ejector from the suction port, so that the above-mentioned disadvantage can be eliminated.

[0005]

As a first means, the lower end of the small-diameter cylindrical portion 4 is formed as an enlarged-diameter cylindrical portion 5 from the lower surface of the liquid ejector 1 attached to the mouth and neck of the container body. Suction cylinder 7 provided with a plurality of spacers 6 and communicating with the cylinder
While hanging the huge-diameter cylindrical portion 5 with the spacer,

The inner surface of the inner wall 12 is airtightly and watertightly in contact with the upper surface of the large-diameter cylindrical portion 5 so that communication between the flange-shaped hole formed by the inner peripheral portion of the upper wall 12 and the free-fitting cylinder chamber is not possible. The lower end of the spacer 6 supports the upper surface of the inward flange-like bottom wall 13 of the loose fitting cylinder by the lowering of the hanging member 11 by its own weight. At this time, the gap between the outer surface of the suction cylinder 7 and the inner surface of the loose fitting cylinder 14 is set. In addition, the gap between the spacers makes it possible to form the inverted liquid suction passage 18 into the suction cylinder 7.

As a second means, the first means is provided, and at the same time, the upper wall 12 of the loose fitting tube 14 is loosely fitted to the suction cylinder 7 or the outer surface of the hanging cylinder to hang laterally. The prevention cylinders 16 and 25 are erected.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a first embodiment shown in FIGS. 1 and 2 will be described. Reference numeral 1 denotes a known liquid in which a mounting cylinder 3 is detachably fitted to the mouth and neck of a container body 2. It is an ejector. In the illustrated example, a so-called vertical pump type liquid ejector is illustrated, but a trigger type liquid ejector may be used. From the lower surface of the liquid ejector, a suction tube 7 having a plurality of spacers 6 attached to the lower surface of the enlarged-diameter cylindrical portion is suspended from the lower end of the small-diameter cylindrical portion 4 as an enlarged-diameter cylindrical portion 5. In the illustrated example, the cylinder 8
The cylindrical portion hanging from the lower end is referred to as a small-diameter cylindrical portion 4, and a huge-diameter cylindrical portion 5.
The fitting tube portion rising from the upper end is fitted into the small-diameter tube portion 4 so that it cannot be pulled out.

In the illustrated example, the enlarged-diameter cylindrical portion 5 is formed into a hemispherical shape having no lower half, but may have a tapered shape with an upper small diameter, and the large-diameter cylindrical portion is suspended from the lower end of the small-diameter cylindrical portion through an outward flange. Shape may be sufficient. The enormous diameter cylindrical portion allows the inner surface of the upper wall of the loose fitting cylinder to be pressed against the upper surface in an airtight and watertight manner,
The upper surface is formed in a shape that can be pressed.

A hanging member 11 is hung from the suction cylinder 7. The member moves the enlarged-diameter portion 5 with spacer into a free-fitting cylinder 14 having an inwardly flanged upper wall 12 and a bottom wall 13 at both upper and lower ends by elastic deformation of one or both of them. It is movably engaged with the inner peripheral edge of the upper wall 12 of the loose fitting tube 14 by engaging with the outer peripheral portion of the upper surface of the enlarged diameter tube portion 5, and the suction pipe 15 is hung down from the lower portion of the loose fitting tube 14. I do.

In the illustrated example, the loose fitting tube 14 is formed into a spherical shape with upper and lower ends opened, and the cylindrical portions 16 and 17 project from the upper and lower ends thereof, and the upper end of the suction pipe 15 is fitted into the lower cylindrical portion 17. They are fixed together. When the loose fitting cylinder 14 is in the upright position shown in FIG. 1, the inner surface of the upper wall 12 of the loose fitting cylinder 14 is in airtight and watertight contact with the outer peripheral portion of the upper surface of the huge-diameter tubular portion 5, thereby forming the inner peripheral portion of the upper wall 12. It is provided so that communication between the flange-shaped hole and the room of the free-fitting cylinder 14 becomes impossible.

As shown in FIG. 2, when the container is inverted, the vertical member 11 descends by its own weight, so that the bottom surface of the bottom wall 13 of the loose fitting cylinder 14 comes into contact with the lower end of the spacer 6 and the suction Cylinder 7
The gap between the outer surface and the inner surface of the free-fitting cylinder 14 and the gap between the spacers 6 make it possible to form the inverted liquid suction path 18 into the suction cylinder 7. The suction passage communicates with the inside of the suction pipe.

When the liquid ejection operation is performed in the upright state of the container shown in FIG. 1, when the pressure in the cylinder 8 becomes negative, the suction pipe
15, the liquid in the container is sucked into the cylinder 8 through the loose fitting tube 14 and the suction tube 7, and when the container body is inverted and the liquid ejection operation is performed as shown in FIG. The lower end of the suction pipe 15 is exposed above the liquid surface 21 in the container body, but the liquid surface 21 is located below the loose fitting cylinder 14 and below the container body and is on the side of the suction pipe 15. In this case, since the liquid suction passage 18 for inversion and the inside of the suction pipe 15 communicate with each other via the gap between the spacers 6 and 6, the liquid level 21a in the suction pipe also changes. Thus, the liquid in the container is sucked into the cylinder through the inverted liquid suction passage 18 and the suction cylinder 7, and is ejected. When the liquid in the container is further reduced and the lower end of the suction tube 7 is exposed above the liquid surface when the container is inverted, the suction tube 7 sucks the air in the container through the suction pipe 15 and is in an inverted state. However, since the amount of liquid remaining in the container at this time is small, it does not cause much trouble. From this state, the liquid in the container can be used up by using the container upright.

FIGS. 3, 4 and 5 show a second embodiment. In this embodiment, as shown in FIG. 5, the enlarged diameter cylindrical portion 5 is formed by projecting tapered cylindrical portions 5b and 5b upward and downward from the upper end and the lower end of the large diameter cylindrical portion 5a, respectively. From the small diameter part at the tip of both tapered cylinder parts to the small diameter cylinder parts 5c, 5c
The upper cylinder portion is fitted into the small-diameter cylinder portion 4 hanging down from the lower end of the cylinder 8 so that it cannot be pulled out, and the lower cylinder portion is provided with vertical split grooves 5d, 5d. The parts are spacers 6 and 6.

The hanging member 11 is provided with an inward flange at an upper end of a cylindrical portion 22 having an inner diameter larger than that of the large-diameter cylindrical portion 5a to form an upper wall 12, and the upper wall is formed on an upper surface of the tapered cylindrical portion 5b. The upper part of the suction pipe connecting cylinder 24 having an inward flange 23 at the upper end is fitted into the lower part of the cylindrical part 22 in an airtight and watertight manner so that it cannot be pulled out. The upper part of the suction pipe 15 is fitted so as not to be able to be pulled out, and the above-mentioned cylindrical part is used as a loose fitting cylinder 14. The bottom wall 13 of the loose fitting cylinder is formed by the inward flange 23, and as shown in FIG. 4, when the container is inverted, the lower ends of the spacers 6, 6 contact the upper surface of the inward flange 23 to support the hanging member 11. Be provided. In the illustrated example, the large-diameter cylindrical portion 25 stands upright from the outer periphery of the free-fitting cylinder upper wall 12 and loosely fits on the outer surface of the cylinder 8, and the large-diameter cylindrical portion comes into contact with the outer surface of the cylinder. 8 so as not to be greatly inclined. The liquid suction passage when the container body is upright and when the container body is upside down is the same as in the case of the first embodiment described above.

FIGS. 6 and 7 show a third embodiment. In this embodiment, a lifting cylinder 31 having both an inward flange 32 and an inward flange 32 at the lower end of the liquid ejector is suspended from the lower surface of the liquid ejector in communication with the cylinder 8. In the illustrated example, the upper part of the hanging cylinder 31 is directly fitted to the outer surface of the lower part of the cylinder 8 so that it cannot be pulled out. However, the hanging cylinder 31 may be indirectly suspended via a separately provided connecting cylinder. The vertically moving member 33 is suspended from the inside of the hanging cylinder 31. The vertical moving member 33 is composed of a valve cylinder 34 and a suction pipe 15 that hangs down from the lower part of the valve cylinder. Then, a plurality of stoppers 38 are provided on the lower outer surface of the small-diameter cylindrical portion. The outer diameter of the large-diameter and short cylindrical portion 35 is smaller than the inner diameter of the hanging cylinder 31 and the outer diameter of the small-diameter cylindrical portion 37 is smaller than the flange hole 32a of the inward flange. Inside, small-diameter tube 37
Are inserted into the inward flange holes 32a so as to freely move up and down, and the downward step portions 36 are mounted on the upper surface of the inward flange 32 in an airtight and watertight manner. An appropriate gap is provided between the stopper 38 and the inward flange 32. When the upper surface of the stopper contacts the lower surface of the inward flange 32 as shown in FIG. To keep away from The suction pipe 15 has a small-diameter cylindrical part 37 as shown in the figure.
The lower portion may have a larger diameter and be fitted inside thereof, or may be fitted to the outer surface of the lower portion without increasing the diameter.

When the liquid ejection operation is performed in the container upright state shown in FIG.
Are in air-tight and water-tight, so that the liquid in the container is sucked into the cylinder through the suction pipe 15, the valve cylinder 34, and the suspension cylinder 31 due to the negative pressure in the cylinder 8, and is ejected.

When the container body is inverted as shown in FIG.
The vertically moving member 33 moves down with respect to the hanging cylinder 31 and the stopper 38
The upper surface contacts the lower surface of the inward flange 32 and the suction pipe 15
The lower end is exposed above the liquid level 21 in the container. In the state where the inward flange 32 is in the liquid in the container, the liquid is filled in the hanging cylinder 31 and the liquid is also in the upper part of the valve cylinder 34, so when performing the liquid ejection operation in this state, The gap between the stoppers 38 and the gap between the inner peripheral surface of the inward flange hole 32a and the outer surface of the small-diameter cylinder 37, and the gap between the inner surface of the suspension cylinder 31 and the outer surface of the large-diameter short cylinder portion 35 form the liquid suction passage 18 for inversion. Then, the liquid enters the cylinder through the liquid suction path and is ejected. When the liquid level 21 is lowered and the inward flange 32 is exposed, air in the container enters the suspension tube 31 and liquid suction becomes impossible, but at this time, the remaining amount of liquid in the container becomes small, The remaining liquid may be used by ejecting the liquid in an upright state of the container, or the liquid may be ejected in the inverted state of the container by replenishing the liquid in the container.

[0019]

According to the first aspect of the present invention, the suction tube 7 is hung down from the lower surface of the liquid ejector 1 and the enlarged-diameter tube portion 5 with the spacer provided at the lower portion of the suction tube is moved from the lower portion of the loose fitting tube 14 to the lower portion. The hanging member 11 hanging down the suction pipe 15 is fitted into the loose fitting tube 14 so as to be vertically movable into the loose fitting tube 14 and the inner surface of the loose fitting tube upper wall 12 is airtightly and watertightly engaged with the upper surface of the huge diameter cylindrical portion 5. Therefore, it is convenient to obtain a liquid ejector that can be used both upside down and upside down by providing only one suction pipe as compared with the conventional example described above. The inner surface of the wall 12 is air-tightly and water-tightly in contact with the upper surface of the huge-diameter cylindrical portion 5 so that communication between the flange-shaped hole formed by the inner peripheral portion of the upper wall and the free-fitting cylindrical chamber becomes impossible.
When the container body is inverted, the lower ends of the plurality of spacers 6 attached to the lower surface of the huge-diameter cylindrical portion 5 are inwardly-flanged bottom walls of the loose fitting cylinder 14.
13 The upper surface is supported, and at this time, the outer surface of the suction
Since the gap between the inner surface and the gap between the spacers can form the liquid suction path 18 for inverted use, the length of the liquid suction path especially for inverted use is shortened to simplify the structure. You can do it.

The second aspect of the present invention has the same effect as the first aspect of the present invention, and also has a structure in which the loose fitting cylinder 14 is freed from the upper wall 12 to the suction cylinder 7 or the outer surface of the cylindrical portion hanging down the suction cylinder. Since the cylindrical portions 16 and 25 are erected and fitted, the inner surfaces of the cylindrical portions 16 and 25 are brought into contact with the suction tube 7 or the tube portion hanging down from the suction tube 7 so that the vertical member 11 with respect to the suction tube 7 is formed. Of the vertical member relative to the suction cylinder 7 is not impaired by the horizontal blur.

In the case of the third aspect of the present invention, the suction pipe 15 is suspended from the lower part of the valve cylinder 34 into the suspension cylinder 31 having an inward flange 32 at the lower end of the cylinder part suspended from the lower surface of the liquid ejector. Since the large-diameter and short cylindrical portion 35 on the upper part of the moving member 33 is loosely fitted and hung down, as in the case of the first aspect of the present invention, only one liquid suction pipe 15 is required, and when the container body is erected, If there is a valve cylinder to the upper surface of the inward flange 32 at the lower end of the suspension cylinder 31
34 The downward stepped portion 36 The lower surface is in airtight contact with the inward flange hole
When the container body is inverted, the upper end surface of the stopper 38 attached to the lower outer surface of the small-diameter cylindrical portion 37 contacts the lower surface of the inward flange 32. A gap between the inner peripheral surface of the tube 32 and the outer surface of the small-diameter cylindrical portion 37 and a gap between the inner surface of the suspension tube 31 and the outer surface of the large-diameter short cylindrical portion 35 form the liquid suction passage 18 for inversion. With the provision, the length of the liquid suction path for inversion can be shortened and the configuration can be simplified as in the case of the first aspect of the invention.
