Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a liquid dispensing container capable of discharging appropriate amounts of liquid for cosmetics, writing, drawing, etc. stored in the container body.

(Prior art and its problems) Japanese Utility Model Application Publication Nos. 59-10712 and 1983-126108 are known regarding a liquid discharge container capable of discharging the liquid stored in the container body.

In the structure disclosed in Utility Model Application Publication No. 59-10712,
The cream-like cosmetics stored in the storage tray are pressed by an elevating plate that rises with the rotation of the inner lid, and are discharged from the discharge hole of the storage tray and the opening of the inner lid. In the structure disclosed in , an inner container having a bellows-shaped side wall is pressed by an operating bottom plate that can be raised and lowered, so that the paste cosmetic in the inner container is discharged from a liquid passage hole in the center of the main body.

However, since both the former elevating plate that presses the stored liquid and the latter operating bottom plate are raised and lowered by a feeding mechanism using screw means, rotational operations are required when raising the elevating plate and the operating bottom plate. However, since it is necessary to visually check the amount of liquid discharged, there are problems in that the adjustment is troublesome.

(Purpose of the invention) The present invention was devised in view of the above-mentioned problems, and aims to provide a liquid dispensing container that can dispense an appropriate amount of liquid stored in the container body with a simple operation. .

(Summary of the invention) The present invention provides a press plate which can be freely pushed into a container body having an inner flange and is prevented from coming off upward by the inner flange, and a space between the press plate and the container body.
A storage chamber made of a soft material that can be contracted and deformed according to the consumption of the liquid to be stored is arranged, and the storage chamber has a normally closed valve on the top surface, and the upper end of the storage chamber is clamped around the opening. a cylinder that is fitted into a hole formed in the pressure plate; a piston that has a normally closed valve on its top surface and a passage in its wall surface and that is slidably fitted into the cylinder; a resilient member that biases downward relative to the piston, wherein a valve of the cylinder opens when the relative position change between the cylinder and the piston is in a pushing direction; Further, when the movement is in the withdrawal direction, the valve of the piston is opened, and the piston is supported by the inner wall of the container body via the wall of the storage chamber, and the pressing plate is The object of the present invention is to provide a liquid dispensing container capable of discharging the liquid stored in the storage chamber by pressing against the elastic force of the elastic member, and to meet the above object.

(Example) Hereinafter, the present invention will be explained in detail based on an example.

In FIGS. 1 and 2, reference numeral 1 is a container body having an inner flange 2 at the upper end, and a pressing plate is provided inside the container body 1, which is prevented from coming off upward by the inner flange 2. 3 is provided so that it can be pushed freely. 4 is a bag-shaped storage chamber made of a soft material arranged in the gap 5 between the container body 1 and the pressing plate 3;
Liquid for makeup, writing, drawing, etc. is stored in the storage chamber 4. Reference numeral 6 denotes a cylindrical cylinder having a normally closed valve 7 on the upper surface, and the cylinder 6 is clamped around the opening 8 at the upper part of the storage chamber 4 by the collar 9 and the lower surface of the pressing plate 3, and the upper end is pressed. It is fixed to the pressing plate 3 by fitting into a hole 11 of a saucer 10 formed at the center of the plate 3. 12 is a hollow cylindrical piston whose lower surface is in contact with the inner surface of the storage chamber 4 and whose upper portion is slidably fitted into the cylinder 6;
1 has a normally closed valve 13 on the top surface, and a passage 14 leading into the storage chamber 4 on the wall surface. In the illustrated example, an O-ring 15 is fitted to the outer periphery of the upper part of the piston 12 that fits into the cylinder 6, but the O-ring 14 is not necessarily required. 16 is an elastic member such as a spring stretched between the cylinder 6 and the piston 12;
The piston 12 is urged downward with respect to the cylinder 6 by the elastic force of the elastic member 16, and the outer stepped portion 1
7 is brought into contact with the inner surface stepped portion 18 of the cylinder 6 and brought into a normal position.

Next, the liquid ejecting operation in the above-mentioned embodiment will be explained using FIG. 3.

When discharging the liquid stored in the storage chamber 4 into the saucer 10, first, an appropriate location (for example, an arrow location) on the upper surface of the press plate 3 is pressed downward. Pressing plate 3
Since it is possible to tilt using the other end portion that is in contact with the inner flange 2 as a fulcrum no matter which part of the upper surface is pressed, it is also possible to move the entire body by pressing at multiple places. Because there is this press plate 3
Due to the movement of the container body 1 through the wall of the storage chamber 4,
Piston 12 and cylinder 6 supported on the inner wall of
This means that the elastic member 16 moves in the pushing direction against the elastic force of the elastic member 16. At this time, the piston 12
The valve 13 of the cylinder 6 is in a closed state, and if the cylinder 6 is filled with liquid in advance, this liquid will be pressurized, opening the valve 7 of the cylinder 6, and discharging the saucer 10.
is discharged.

Further, when the pressure of the press plate 3 is released, the piston 12 and the cylinder 6 move relative to each other in the withdrawal direction due to the elastic force of the elastic member 16. At this time, the valve 7 of the cylinder 6 is closed, and the inside of the cylinder 6 becomes negative pressure, while the valve 13 of the piston 12 is opened, and the cylinder 6 is filled with liquid flowing from the passage 14. Incidentally, since the storage chamber 8 shrinks and deforms as the stored liquid is consumed, the cylinder 6 is reliably filled with the stored liquid until the end.

In this way, the liquid filled in the cylinder 6 can be discharged into the saucer 10 by pressing an appropriate part of the upper surface of the pressing plate 3 and pushing the pressing plate 3 into the container body 1. If the pressing of the plate 3 is released, the liquid can be filled into the cylinder 6 again, so that an appropriate amount of liquid stored in the storage chamber 4 can be discharged into the saucer 10 by a simple pressing operation.

Note that the inner flange 2 provided at the upper end of the container body 1 may not be provided all around the circumference as in the illustrated example, but may be provided partially.

(Effects of the invention) As described above, according to the invention, an appropriate amount of liquid stored in the container body can be dispensed by an extremely simple operation of pressing the appropriate part on the top surface of the pressing plate and pushing the pressing plate into the container body. Can be discharged.

Moreover, the discharge amount can be varied not only by tilting the press plate using the contact part with the inner flange as a branch or by moving the entire press plate, but also by tilting the press plate and moving the entire plate. It remains constant regardless of the degree of consumption of the liquid, and the amount of liquid that remains unconsumed can be sufficiently suppressed, allowing the stored liquid to be used effectively. Furthermore, deterioration of the liquid due to the negative pressure inside the liquid storage chamber can be suppressed as much as possible. In this way, with a simple pressing operation, there is no waste, and
The liquid can be reliably ejected in an appropriate amount, including over time.
