[0001]

The present invention relates to a liquid ejector.

[0002]

2. Description of the Related Art As a liquid ejector, for example, a liquid ejector provided with a container body having a mouth and a neck rising from a body and a push-down head type pump mounted on the container body is generally known. In these pumps, for example, the upper part of a cylinder hanging down into the container body is fixed by a mounting cap fitted to the mouth and neck, and a pipe fitted to a suction port at the lower end of the cylinder is hung down at the bottom part in the container body. Further, a vertical moving member is provided in which an upper end of a stem in which an annular piston internally fitted in the cylinder is projected from a lower outer periphery is projected above an upper end opening of the cylinder, and an ejection head is fitted and fixed to the upper end. . In addition, a suction valve is provided at the lower end of the cylinder, and a discharge valve is provided at the upper part of the stem, and the vertically moving member is constantly urged upward by a coil spring or the like. It is configured such that the liquid in the container is sucked up and spouted from the spout of the head.

[0003]

In this type of conventional ejector, generally, one kind of liquid is stored and ejected in a container body. However, recently, these ejectors are insoluble and specific gravity of each other. It has also been practiced to store two different liquids, mix the two liquids by shaking the container immediately before use, and use them by jetting.

However, stirring and mixing the two liquids by shaking the container is troublesome in itself. In some cases, sufficient mixing is not produced unless the container is vigorously shaken.
Since the lower end opening of the suction pipe exists in the lower part of the container body, only the heavy liquid below may be ejected, and it is difficult to always eject the mixed liquid having substantially the same mixing ratio. In addition, depending on the type of the two liquids, once mixed liquids are separated quickly, and it is necessary to eject the liquid immediately after stirring.

Further, if the two liquids are stored in separate ejectors and ejected, respectively, such inconvenience can be solved, but the two ejectors are required, which is uneconomical, and the storage is bulky. There are inconveniences.

The present invention has been made in view of the above points, and two liquid insoluble liquids having different specific gravities can be simultaneously stored in a single liquid ejector so that the liquid is not bulky. The present invention proposes a liquid ejector which can always eject two liquids having substantially the same mixing ratio without requiring the same, is easy to use, has a simple structure, and is easy to manufacture.

[0007]

In order to solve the above-mentioned problems, the spouting device according to the present invention is characterized in that the mouth and neck portion 5 is erected from the body portion 4 and the inner surface of the outer layer 2a having a shape-retaining property is flexible. Inner layer
A container body 2 in which two insoluble liquids having different specific gravities are stacked, and a lower end hanging down to the upper part of the container body is bifurcated into a first suction port 8 and a second suction port. 9 and a liquid ejecting pump 3 of a down-head type, the upper end of which is communicated and fixed to the first suction port 8, and the lower end of which is provided with a pipe 13 having a lower end hanging down on the bottom of the heavy liquid A in the lower part of the container. An opening is formed as a first suction port a for heavy liquid, and a second suction port 9 opened above the light liquid B is formed as a second suction port b for light liquid. .

Further, in the jetting device according to the second aspect of the invention, a vertically long protective wall 15 capable of introducing a liquid into the second suction port b is provided below the lower end of the second suction port b. The liquid ejection device according to claim 1 is configured.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

The liquid ejector 1 according to the present invention includes a container body 2 and a pump 3 of a down-head type.

The container body 2 is formed by erecting the mouth and neck portion 5 from the cylindrical body portion 4 and laminating a flexible inner layer 2b on the inner surface of an outer layer 2a having shape-retaining properties. By inner layer
This is configured so that 2b is peeled off and the internal volume of the remaining liquid is substantially maintained. In addition, two insoluble liquids having different specific gravities are accommodated inside. In the two liquids, a heavy liquid A having a high specific gravity is stored in a lower layer, and a light liquid B having a low specific gravity is stored in an upper layer.

The press-down head type pump 3 is constructed by pushing a jet head at the upper end which is conventionally used.
It is possible to use the one configured to eject liquid from the ejection port of the ejection head, provided that the lower end hanging down to the upper part of the container body is configured as a forked first suction port and a second suction port, and the internal mechanism is The internal mechanism of this type of conventional pump can be adopted.

In the illustrated example, a lower end of a cylinder 7 having an upper end fixed by a mounting cylinder 6 screwed to the outer periphery of the mouth and neck portion 5 is hung down on the upper part of the container body, and a first suction port 8 branched into two at the lower end is provided. The second suction port 9 is opened in the upper part of the container. Also, a stem 10 protrudes from the upper end opening of the cylinder, and a vertical moving member is provided at the upper end of which a jet head 12 with a jet port 11 is fitted and fixed. By moving the vertical moving member up and down, a built-in pump is provided. A well-known pump mechanism configured to suck up the liquid in the container body by the action of the mechanism and eject the liquid from the ejection port 11 is provided.

In the present invention, an upper end is connected to and fixed to the first suction port 8, and a pipe 13 whose lower end is hung down on the bottom of the heavy liquid A in the lower part of the container is provided. The second suction port 9 is formed as the second suction port b for the light liquid, and the second suction port 9 opened at the upper portion of the light liquid B is not provided with the port a.

The position of the first suction port a may be any position close to the bottom wall of the container body, and the position of the second suction port b may be an upper part in the container body. The inner layer 2b that is peeled off by the ejection of the liquid by the pump 3 does not seem to be peeled off in principle, and the interface 14 between the heavy liquid A and the light liquid B seems to move up and down depending on the peeled position. There is no problem when the interface 14 moves downward, and when the interface rises, it is inconvenient if it goes above the second suction port b. Therefore, the interface
It is preferable to open the upper part of the second suction port b so that it does not become higher than the second suction port b even if it rises. Specifically, although it is impractical, even if it is assumed that only the lower half of the inner layer 2b has peeled off and the liquid has become half, if the trunk has the same diameter from top to bottom, At least at least 3/4 or more of the upper part of the torso can be reliably prevented. This point may be appropriately selected depending on the size of the container, the shape of the body, and the like.

In the illustrated example, the first suction port 8 and the second suction port 9 are formed integrally with the cylinder. However, by providing a connecting member separate from the cylinder, for example, the upper part is located at the lower end of the outer periphery of the cylinder. It is also possible to provide a connecting member that is fitted in a liquid-tight manner and has a lower part formed in two branches. Also, the inner diameter of the first suction port a and the second suction port b may be the same or different,
If they differ, it is preferable to adjust the storage amounts of the heavy liquid A and the light liquid B, respectively.

A description will be given of a case in which the above-described ejector 1 is used. After the ejection head 12 is pushed down to eject the liquid from the ejection port 11, when the pressure of the head is released and the operation member rises, the first The heavy liquid A flows from the suction port a to the second suction port b.
, The light liquid B is sucked into the cylinder 7 respectively. With the suction of each liquid into the cylinder 7, the amount of each liquid in the container body 2 decreases, and as a result, the inner layer 2b becomes negative pressure and the inner layer 2b becomes the outer layer.
Partially peeled off from 2a.

FIG. 2 shows another embodiment. In this embodiment, a vertically long protective wall capable of introducing a liquid into the second suction port b below the lower end of the second suction port b is provided. 15 are hanging.

When the amount of residual liquid stored in the protective wall 15 is reduced, the inner layers 2b of the container body are locally in contact with each other below the second suction port b, so that the suction of the light liquid B is deteriorated. It is to prevent that. Even if the protective wall 15 is not present, if the stored liquid is large, the second suction port b due to contact between the inner layers 2b
It seems that there is almost no inconvenience such as blockage of the inner layer 2b.However, when the residual liquid is reduced, most of the inner layer 2b is peeled off from the outer layer 2a, and the protection wall 15 prevents the second suction port b from being blocked. As a result, the two liquids can be ejected until the remaining amount of the stored liquid becomes considerably small. still,
In the case of the first suction port a, since the first suction port a is opened at the lower end portion of the container, there is no inconvenience such that the inner layers 2b contract and close below each other.

The protective wall 15 in the illustrated example is formed by vertically suspending a pair of vertically long rectangular plates having a horizontal cross-section from the lower surface of the pump 3 sandwiching the second suction port b. The center side edge of each long plate is in contact with the pipe 13.

Incidentally, the protective wall 15 is not limited to the one shown in the figure, but is configured so that liquid can be introduced into the second suction port b, and the blockage by the inner layer is physically prevented therebelow. If so, various forms can be selected. For example, it is possible to adopt a cylindrical shape in which a cut groove is provided vertically, and the length is not limited to the length extending to the lower portion of the inside of the container as in the present embodiment, but may be short.

[0022]

As described above, the liquid ejector according to the present invention has the above-described structure, and thus does not require two containers, does not require two pumps, and has a specific gravity different from each other. The two liquids can be stored at the same time so that they are not bulky, and the mixed liquid can be simultaneously discharged, so that the two liquids can be stored and discharged very conveniently and conveniently. Also, there is no trouble such as shaking and mixing the stored liquid by shaking the container body, and there is no danger that the liquid having an insufficient mixing ratio and a non-uniform mixing ratio is jetted out, and the liquid having the substantially same mixing ratio is always jetted out. Is what you can do.

[0023] Further, it has a simple structure, and as a result, it has an advantage that it is easy to manufacture and can be obtained at low cost. Further, the outside air is not introduced into the inside due to the ejection of the liquid and is kept in contact with the air. This is convenient for storing an inconvenient liquid.

Further, in the pump according to the second aspect of the present invention, the presence of the protective wall prevents the shrinking inner layer from closing the second suction port, so that the liquid can be reliably sucked from the second suction port. is there. In particular, it is possible to prevent the second suction port, which tends to be generated when the residual liquid is reduced, from being blocked, and to efficiently eject the two liquids until the residual liquid is reduced.
