Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a discharge container configured to discharge a liquid. As liquids, cosmetics such as eyeliner, lip color, foundation, writing liquid such as ink and paint, mayonnaise,
Cooking ingredients such as tomato ketchup, mustard, cooking oil,
Other examples include machine oil and toothpaste.

(Prior Art) There are various discharge containers. For example, a liquid storage chamber that decreases in volume as the discharged liquid is consumed, a volume change chamber that reduces and recovers volume by the addition or removal of an external force, and a liquid in the liquid storage chamber that changes in volume when the volume of the volume change chamber is recovered. The first valve, which serves as a liquid inlet for the volume change chamber, is opened so as to be introduced into the change chamber, and the valve is opened so as to draw out the liquid for the volume change chamber when the volume of the volume change chamber is reduced. There is also a discharge container having a liquid passage formed by a second valve serving as a liquid outlet.

(Problems to be Solved by the Invention) The above-described discharge container has the advantage that the pressing amount can be set appropriately. However, the liquid stored in the liquid storage chamber is only one type, and when using a plurality of liquids,
It is necessary to prepare as many discharge containers as the number of kinds of liquids. This is extremely inconvenient to handle during use.

A specific example will be given. When the above-mentioned discharge container is a cosmetic product, a plurality of cosmetic products are often carried in a handbag or the like. At this time, a large amount of cosmetics will be taken inside the handbag. Also, even if it is provided on a table such as mayonnaise and tomato ketchup, not only do you have to have many things to mix and use, but also each discharge container for mixing. Must be picked up and ejected.

Therefore, an object of the present invention is to provide a discharge container that is easy to handle during use.

(Means for Solving the Problem) The liquid storage chamber is a container body divided into a plurality of parts. Of course, each container body must decrease in volume as the liquid to be discharged is consumed. That is, the present invention provides a liquid storage chamber that decreases in volume as the liquid to be discharged is consumed,
A volume change chamber that undergoes a volume reduction recovery by adding or removing an external force, and a liquid inlet for the volume change chamber that opens the valve to introduce the liquid in the liquid storage chamber into the volume change chamber when the volume change of the volume change chamber is restored. And a liquid passage formed by a second valve that serves as a liquid outlet of the volume change chamber when the volume of the volume change chamber decreases, and a pressing portion that applies an external force for the volume change chamber. And a liquid container having a plurality of divided liquid storage chambers, the outlet center of the liquid storage chamber and the center of the liquid passage are made different, and from each of the liquid storage chambers. Of the liquid is squeezed by the first valve and introduced into the volume change chamber and mixed in the volume change chamber. Further, when the liquid flows out from the volume change chamber, the liquid is also mixed by the second valve. Mixed like a squeak Rutotomoni, the gist of the discharge vessel which made different from the center of the outlet center and a liquid passage of the liquid containing chamber including a plurality.

(Embodiment) A first embodiment will be described with reference to the attached FIGS. 1 and 2.
It should be noted that the expression about directions such as "up, down, left and right" in the following means the directions in FIG.

Reference numeral 1 indicates a container body, and the discharge port 2a is sequentially arranged from above.
And a piston 4 mounted below the inside of the pressing body 2 and having an upper valve 3 mounted on its upper surface, and a lower valve arranged on the upper surface so as to slide in a liquid-tight manner relative to the piston 4. 5, a cylinder 6 to which 5 is attached, an elastic member 7 such as a coil spring that is stretched between the piston 4 and the cylinder 6 and applies a force in a direction separating them from each other, and an opening member disposed below the cylinder 6. 8, soft bags 9 and 10 for accommodating the liquid, which are respectively attached to the openings 8a and 8b of the opening member 8, are arranged. Here, the number of the bag bodies 9 and 10 which are the container bodies in this example can be appropriately set to two or more.
Reference numeral 1a is an air hole provided in the container body 1.

Although illustration is omitted, the upper valve 3 and the lower valve 5 are disc-shaped as a whole having a “C” -shaped notch, and are the second valve and the first valve in this example, respectively. Both can only open upwards. In addition, the cylinder 6 has bags 9,10
A through hole 11 that communicates with the opening portion 8a of the opening member 8 is formed so that the liquid therein can reach the lower valve 5.
A volume change chamber 12 is provided between the upper valve 3 and the lower valve 5.

That is, when a force in the direction of bringing the upper valve 3 and the lower valve 5 closer to each other is applied to the pressing body 2 against the force of the elastic body 7, the upper valve 3 is opened and the liquid in the volume change chamber 12 is discharged. The volume of the volume change chamber 12 decreases while being led to 2a, and when the applied force is removed, the elastic force of the elastic body 7 opens the lower valve 5 to remove the liquid in the bags 9 and 10. The volume changing chamber 12 recovers its volume while being introduced into the volume changing chamber 12.

The bag body is formed by repeating such simple pressing of the pressing body 2.
The liquid in 9, 10 is gradually discharged, but as shown in FIG. 2, the through hole 11 of the cylinder 6 forms an appropriate opening amount with the opening portion 8a of the opening member 8, and therefore, The liquid in the bags 9 and 10 is discharged in accordance with the amount of the openings.

The above is the basic part, but the present example has some further improvements in two points, which will be described.
The first point is that the cylinder 6 is rotatably attached to the container body 1. That is, the through hole of the cylinder 6
11 is not concentrically arranged with respect to the center of the container body 1, and therefore, when the cylinder 6 is rotated with respect to the container body 1, the through hole 11 is formed between the opening portion 8a of the opening member 8. The amount of apertures formed in step 2 changes, and the amount of liquid discharged from the bags 9 and 10 can be adjusted. The liquid may be any suitable, for example,
In the case of cosmetics, even a single pink consisting of red and white has subtly different tastes depending on the individual. Also,
Preferences change from time to time. Therefore, it is extremely desirable that an individual can adjust the discharge amount of the liquid in the bags 9 and 10. The same applies to the case of seasonings. In addition, such a discharge amount adjustment by the rotation of the cylinder 6 is performed by the through hole 11 of the cylinder 6 and the opening portion of the opening member 8.
This is due to the relative positional relationship with 8a, and may be satisfied with an appropriate shape and appropriate relationship.

Next, the second point is that the liquid discharged from the bags 9 and 10 is in a non-separated state in the portion of the through hole 11 of the cylinder 6. The mixed solution is started from the stage before passing through the lower valve 5. In such a case,
The through hole 11 portion of the cylinder 6 becomes a part of the liquid storage chamber. However, if the liquid is highly viscous, even if there is a partial non-separation inside the liquid storage chamber due to the through hole 11, the bag 9 Unnecessary mixing of liquids in 10 and 10 is negligible. In the present invention, the phrase "becomes a container body in which the liquid storage chamber is divided into a plurality of portions" includes such an incomplete division. In the case of a liquid that requires complete division, the partition wall that divides the through hole 11 of the cylinder 6 should be in contact with the lower valve 5 and that the plurality of openings 8a should be divided. , The lower valve 5 attached to the cylinder 6 instead of the lower valve 5 formed in the central portion of the opening member 8, or separately from this lower valve 5, a valve that opens only upward is formed into the bag body 9, 10 or open. It may be attached to the opening 8a of the hole member 8 or the like.

Next, a second embodiment is shown in FIGS. The same reference numerals are used for the basically same parts as in the previous example (the same applies hereinafter).

The difference of the present example from the previous example is that the upper valve 3 has a generally rectangular shape having a "U" -shaped notch attached to the pressing body 2, and the pressing body 2 and the cylinder 6 are integrated. That the vertical relationship between the piston 4 and the cylinder 6 is reversed, the attachment of the bag bodies 9 and 10 to the aperture member 8 is changed from the inside of the aperture portion 8a to the outside, and
A protrusion 2b is provided on the outer lower end of the pressing body 2, and a vertical groove 4a for engaging the protrusion 2b is provided on the piston 4, so that the pressing body 2 can move up and down with respect to the piston 4 and If the rotational force to the container body 1 is applied to 2, the piston 4
This is because it is possible to adjust the opening amount by the through hole 11 and the opening portion 8a of the opening member 8. An example is shown in which the shape, the integrity of the parts, the positional relationship, the operability, etc. can be appropriately set.

Next, FIG. 5 shows a third embodiment. This example is also different from the previous two examples in some points such as the integrity of the parts, but the biggest difference is that instead of the soft bags 9 and 10, the opening part of the opening member 8 is formed. Hard cylindrical bodies 13 and 14 screwed to 8a,
The sealing members 15 and 16 inserted into the bottoms of the cylindrical bodies 13 and 14 are used. The sealing members 15 and 16 are tubular members 13 and 14, respectively.
When the internal pressure of the device decreases, it moves upward accordingly.
That is, there is shown an example in which the volume can be reduced as the liquid is consumed even if the liquid storage chamber is not a soft one, and a cartridge which can be replaced if necessary. What corresponds to the lower valve 5 can be attached to the cylindrical bodies 13 and 14 as the cartridge.

In addition to the above, various things can be done. For example, the entire shape may be flat, or the discharge port 2a portion of the pressing body 2 is provided with a seal body generally called a virgin seal for improving the hermeticity until the start of use. It may be provided with a tray part for receiving the liquid discharged from the discharge port 2a of the pressing body 2, or an application part made of a porous elastic body or a brush tip such as having a communicating vent hole. It is also possible to have a puff or the like as a product, or to appropriately have a cap, and a plurality of container bodies are not positioned in parallel. Alternatively, as shown in FIG. 5, when a hard container is used, liquid discharge due to unnecessary pressure can be easily suppressed even if the container body is omitted, and the valve can be self-contained. Elasticity Instead, it may have a separate elastic body for opening and closing. Further, the relationship between the opening portion 8a of the opening member 8 and the through hole 11 is made so that only the liquid in one container body can be discharged, or
By sealing all the openings 8a depending on the positional relationship, it is possible to store the openings 8a when not in use.

(Effect of the Invention) Not only has the advantage that the pressing amount can be set appropriately, but it is also possible to reliably mix a plurality of types of liquids, and it is also possible to easily change the mixing ratio of each liquid. .
