Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container in which a desired amount of liquid in a container can be blown out from an outlet by making the container upright or tilting.

[0002]

2. Description of the Related Art Liquid reagents, liquid detergents, purified water, diluents, lubricants, etc. have been conventionally used for semi-rigid liquid containers formed of a flexible synthetic resin such as polyethylene into a size that can be held by hand. Various liquids such as oil are contained, and used to discharge the required amount from the outlet at a suitable time.

By the way, in the liquid container with the outlet as described above, there is a method of use according to the application, such as when the outlet is used upward, when it is inclined, or when it is used downward. is there.

In a liquid container which is used with its outlet mainly facing upward, a pouring pipe whose tip reaches the bottom of the container is provided in the container, and the peripheral side wall of the container is manually pressed to control the atmospheric pressure in the container. When the liquid is raised, the liquid in the container can be appropriately blown out at a desired fixed angle through the pouring pipe.

[0005]

However, in the case where the spout pipe communicating with the spout is suspended in the container as described above,
When the container is tilted or inverted, there is a problem that the liquid cannot be poured out because the base end of the pipe is located above and is located in the head space (upper air portion).

Further, the air in the container expands and contracts due to the fluctuation of the room temperature while the container is not used, and the liquid surface in the container is pressed, so that the liquid is pushed out to the outlet.
Since it may drop out and naturally leak outside, such a minute leak may be a problem not only when cleaning the surrounding area but also when precision is required for chemical experiments.

Further, in the above container, when the liquid is poured out by pressing the peripheral side wall with a hand and then the force of the hand is loosened, the outside air is sucked into the container through the pouring pipe and bubble in the liquid. Therefore, oxygen, carbon dioxide, or other unspecified gas in the air dissolves in the liquid, and in a chemical experiment or the like, the dissolution of such a minute amount of gas may cause a problem such as degrading the precision of the experiment. there were.

[0008]

A liquid container according to the present invention is intended to solve the above-mentioned problems, and two inflow ports are formed in a branched shape in a pouring pipe hung in the container, and one of them is a container. The valve body is characterized in that the valve body is opened near the inner bottom portion and the other is opened near the container inner ceiling portion, and the inlet is provided with a valve body that closes only one of the upper portions by gravity.

[0009]

Operation Even if the posture of the container is changed, the inflow port located below is always opened so that the liquid can be blown out. Therefore, the container can be used without any change whether it is upright or tilted or inverted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The container 1 in the figure is formed of a synthetic resin such as polyethylene with a quasi-rigidity, and a lid 3 is screwed into an upper end opening 2 of the container 1. Then, the spout tube 4 is inserted through the lid 3. Reference numeral 5 denotes a tapered nozzle-like outlet that is detachably attached to the protruding end of the spouting pipe 4 outside the container 1. The outlet pipe 4 is a container 1
A straight tubular branch pipe 6 that hangs inside and branches in a forked shape in the vertical direction is connected to the tip thereof. A trumpet-shaped inlet port 7 opens at one end of the branch pipe 6 near the inner bottom of the container 1, and a trumpet-shaped inlet port 8 opens at the other end near the ceiling of the container 1. .

Further, a linear shaft 10 is movably inserted so that a sufficient gap 9 exists in the branch pipe 6, and one end of the shaft 10 is projected outward from the inflow port 7 and the protruding portion is A spherical valve body 11 is formed which forms a spherical valve body 11 capable of opening and closing the inflow port 7, and which projects the other end of the shaft 10 outward from the inflow port 8 and can open and close the inflow port 8 at the protruding portion. To form. The numeral 13 indicates a liquid contained in the container 1 by about half. The shaft 10, the valve body 11, and the valve body 12 are made of a material such as glass or metal having a specific gravity larger than that of the liquid 13 so as to be submerged in the liquid 13 by gravity.

In the upright state of this liquid container, as shown in FIGS. 1 and 2, the valve body 12 is lowered by gravity to close the inflow port 8, while the valve body 11 is separated from the inflow port 7. The inlet 7 is open in the liquid 13 since it is retained. For this reason, when the peripheral side wall of the container 1 is pressed by hand in this upright state, the inflow port 8 is closed.
The air pressure in the inside rises, and the liquid 13 can be extruded from the inflow port 7 to the ejection pipe 4 and ejected from the ejection port 5.

Further, when the container 1 is tilted downward as shown in FIG. 4, the valve body 11 closes the inflow port 7 by gravity, and conversely, the valve body 12 opens the inflow port 8, so that the liquid 13 can be blown from the inflow port 8 through the pouring pipe 4 to the blowout port 5.

As described above, in the container 1, whether the holding posture is upward, downward, or slanted, only the inflow port located below is always opened, so that the inside of the container 1 is opened. Almost all of the liquid can be blown out at any angle.

When the pressure inside the container 1 becomes negative by loosening the force of the hand pressing the peripheral side wall of the container 1, outside air flows into the container 1 through the outlet 5 and the spout pipe 4. At that time, the valve body located above either the valve body 11 or the valve body 12 (in other words, the valve body located in the air in the container 1) is separated from the opening by the negative pressure, and the inside of the container 1 is separated. Since air is introduced into the liquid 13, bubbling rarely occurs in the liquid 13.

Further, when not used in this container and placed in an upright state, one inflow port 8 is located in the head space (upper air portion) in the container 1 as shown in FIGS. Since the air in the head space expands or contracts due to room temperature fluctuations, the pressure in the dead space changes slowly so that the dead space air flows between the valve body 12 and the inlet 8. The pressure inside the container 1 does not fluctuate significantly by moving in and out through a slight gap. Therefore, the liquid in the container 1 does not leak to the outside due to changes in room temperature.

Further, even when the peripheral side wall of the container 1 is grabbed by hand and the liquid is blown out, the air in the head space can enter the branch pipe 6 from the inflow port located above, so that hand If the grip force is loosened a little, the liquid in the spout pipe 4 is cut off. For this reason, by holding the container 1 several times as necessary, it is possible to always blow out a desired amount of liquid without blowing out a large amount of liquid at one time.

In this embodiment, the valve bodies 11 and 12 are connected by the shaft 10 so that they can move integrally. However, even if they are not necessarily connected integrally, they are separate bodies as shown in FIG. May be That is, in the embodiment shown in FIG. 5, the valve seat portions 14 and 15 are formed by narrowing the inner diameters at both ends of the branch pipe 6, and the valve seat portions 14 and 15 are further extended with a plurality of inward facing pawls. To form the separation prevention pieces 16 and 17,
Spherical valve bodies 11 and 12 are swingably disposed between the valve seat portions 14 and 15 and the separation preventing pieces 16 and 17, respectively, and when the valve bodies 11 and 12 descend due to gravity, the valve seat portion 14 is moved. , 15 so that the opening thereof is closed. With such a configuration, the same operation as described above is performed.

Further, in the embodiment shown in FIG. 5, a flexible bellows portion 18 is provided at the protruding portion of the spouting pipe 4 in the container 1, so that the branch pipe 6 can be freely moved in the container 1 according to the posture of the container 1. To be able to move. By doing so, the inflow port 7 always moves to the lower part of the inner bottom of the container 1, so that the liquid in the container 1 can be more completely discharged.

Although the above embodiments have been described with reference to a semi-rigid container made of synthetic resin, it goes without saying that a rigid glass or metal container may be used. Further, the present invention can also be applied to a so-called spray can in which a pressurized gas is filled in the container to eject the liquid in a spray form, or a container having a manual or electric pump for pumping the liquid into the pouring portion. .

[0021]

As described above, according to the present invention, the liquid inside can be blown out regardless of the posture of the container, so that the liquid can be blown upward, downward or obliquely depending on the application. This has the effect of improving usability.
