Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for instantaneously mixing and taking out fluids contained in a plurality of containers in a required time, and an apparatus for carrying out the method.

Traditionally, in cosmetics, medicine, food, etc., different types of fluids were stored in separate containers.
When mixing these fluids during use to obtain the desired product, the mixing ratio of the fluids must be accurate, and if the fluids are an oxidizing agent and a reducing agent, they must react safely. There is. An example of a product that uses a combination of an oxidizing agent and a reducing agent to react is an aerosol hair dye.

However, in the case of this aerosol type hair dye, there are almost no mixing methods or devices that can be easily used by general users, and the commonly used means are one part...H ₂ O ₂ and two parts...
… Store the hair dye base (para-tolylene diamine, para-amino diphenylamine, sodium sulfite, 50% alcohol, etc.) in separate containers, and mix them in another container before use. was.

Similarly, as an example of mixing and reacting two fluids,
There is hot shaving cream. This is done by storing the 1st part...H ₂ O ₂ and the 2nd part...shaving base (shaving cream stock solution, K ₂ SO ₃ , gas, etc.) in separate containers. A mixed reaction is performed to obtain a heated foamy cream, but it is inconvenient for the user to put the above liquids 1 and 2 into another container and mix and _react . There was also the risk of O ₂ adhering to the skin and causing burn-like injuries.

This invention was made in view of the above circumstances,
Its purpose is to collect many types of gases and liquids into one
To enable even general users to easily obtain desired products mixed in accurate ratios by storing them in separate containers and rapidly mixing, reacting, and ejecting them during use. It is in.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The method of the present invention and the apparatus for carrying out the method will be described in detail below with reference to drawings showing embodiments.

The reference numeral 1 in the figure is a container body, and this container body 1 can withstand the pressure of the compressed gas stored therein.
This mountain 2
A through hole 4 is formed in the center.

A housing 5 is airtightly attached to the mountain 2 of the container body 1 via a stem rubber 6, and the housing 5 is integrally formed with a first housing 7 on the upper side in the drawing and a second housing 8 on the lower side in the drawing. This is what I did. The first housing 7 has an insertion hole 9 formed at the upper center in the drawing into which a stem (to be described later) is inserted, and a gas filling hole 10 formed at an arbitrary side wall for ejecting fluid from the inside to the outside. A filling valve 11 for preventing backflow is provided, and a cylindrical stopper 12 having a tapered surface facing downward is formed. Further, the second housing 8 has a first orifice 14 formed in the inner bottom surface 13 thereof, is communicated with an appropriate position in the container body 1 via a tube 15, and is appropriately spaced from the first orifice 14. in position, second
An orifice 16 is formed and communicated with another fluid container 17.

A piston member 18 that is movable in the vertical direction in the drawing is inserted into the housing 5, and the piston member 18 has a press valve 19 at its lower portion that abuts the first and second orifices 14 and 16 to close them. A first spring 21 is interposed between the stepped portion 20 on the outer circumferential surface and the inner bottom surface 13 of the housing 5, and is always urged upward. An engaging part 22 is formed, a plurality of notches 23 are formed above the engaging part 22 in order to facilitate its elastic deformation, and a recessed part 24 facing the first housing 7 is formed in the upper part. , and a through hole 25 is formed in the center.

In addition, a stem 2 is provided in the center of the housing 5.
6 is inserted, and this stem 26 is in liquid-tight contact with the stem rubber 6 and is movable in the vertical direction in the drawing, and the recess 2 of the piston member 18 is inserted in the intermediate portion.
A first flange 27 that abuts on the second housing 7 is formed between the first flange 27 and the second housing 7.
A second spring 28, which is relatively stronger than the spring 21, is inserted so that the entire body is always urged downward as shown in the figure, and a second collar 29 is provided at the bottom with a distance from the lower end surface of the through hole 25 of the piston member 18 in the figure. A passage 30 for communicating the outside air with the inner bottom surface 13 of the second housing 8 is formed in the axial center portion, and a circumferential groove 31 is formed in the outer peripheral portion protruding from the mountain.

Note that reference numeral A indicates a mixing chamber appropriately formed between the inner bottom surface 13 of the second housing 8 and the piston member 18.

Hereinafter, the operation of this invention configured as described above will be explained.

On the right side of FIG. 3, one liquid is stored in a fluid container 17, and this fluid container 17 itself is formed to have flexibility so that it can be squeezed out by the fluid pressure within the container body 1. If compressed gas is sealed together with liquid 2 in liquid 1, liquid 1 and liquid 2 will flow through each orifice 14 and 1 under the pressure of the compressed gas.
6 and attempts to discharge it into the housing 5. At this time, each of the orifices 14 and 16 is closed by the pressure valve 19 pushed by the urging force of the second spring 28, so that mixing of the first and second liquids is not performed under normal conditions.

Next, when an operating member (not shown) or the like is engaged with the circumferential groove 31 of the stem 26 and the stem 26 is operated in the direction of arrow A on the left side of FIG. A gap is created between the two and 24. At this time, the piston member 18 has the engaging portion 22 supported by the stopper 12 of the housing 5,
Since the upward movement in the drawing is stopped against the biasing force of the first spring 21, the gap between the recess 24 and the first collar 27 gradually increases. Next, the second collar 29 of the stem 26 comes into contact with the lower end surface of the through hole 25 of the piston member 18, and moves the entire piston member 18 upward in the diagram against the locking action of the stopper 12 of the housing 5. shall be.

At this time, if the force for operating the stem 26 in the direction of arrow A on the left side of FIG. The engaging portion 22 can be slid along the tapered surface of the stopper 12 and elastically deformed toward the center so that the engaging portion 22 can overcome the stopper 12, thereby releasing the locking action.
By releasing this locking action, the piston member 18
is rapidly moved upward in the drawing by the biasing force of the first spring 21 by the distance between the first collar 27 and the recess 24 described above. Further, at this time, the notch 23 formed in the engaging portion 22 of the piston member 18 functions to facilitate elastic deformation of the engaging portion 22.

When the piston member 18 is moved rapidly, the fourth
As shown on the right side of the figure, the pressure valve 19 and each orifice 1
4 and 16 is released, and the fluid container 17
The first and second liquids stored in the container body 1 are transferred from the orifices 14 and 16 to the housing 5.
They are simultaneously discharged into the interior of the mixing chamber A, mix and react with each other in the mixing chamber A, and become the required mixed fluid through the passage 30 of the stem 26 and are jetted out to the outside. That is, in this embodiment, since the compressed gas in the container body 1 also discharges the fluid in the fluid container 17 at the same time, the cross-sectional area and shape of each orifice 14 and 16 are adjusted depending on the viscosity of the fluid. , it is possible to mix fluids in the desired ratio.

Furthermore, as shown on the right side of FIG. 4, if the stem 26 is maintained in the upper part of the figure against the biasing force of the second spring 28, it is possible to continuously eject the mixed fluid, but the ejection To stop the system, simply release the stem 26. That is, stem 2
6 in the free state, the second spring 28 moves the piston member 18 in the direction of arrow B via the first collar 27, and the pressure valve 19 closes each orifice 14, 16. rapidly occludes. At this time, the engaging portion 22 of the piston member 18 is
It will ride over the stopper 12 of the housing 5 and then re-engage. When the pressure valve 19 closes each orifice 14, 16, the fluid discharge is stopped and the state shown on the right side of FIG. 3 is returned. The same operation is then repeated as the fluid is ejected.

On the other hand, FIG. 5 explains the operation of filling compressed gas into the container body 1, in which the stem 26 is moved slightly upward in the figure and the gas supply device and stem 2 are connected as appropriate.
When the passage 30 of the stem 6 is connected, the gas flows through the stem 2.
The gas is filled into the container body 1 through the passage 30 of No. 6, the mixing chamber A, the through hole 25 of the piston member 18, the gas filling hole 10 of the first housing, and the filling valve 11, respectively. The filled gas is not released to the outside when the stem 26 is not operated because the filling part 11 has a backflow prevention effect and the first orifice 14 is also closed by the pressure valve 19. Alternatively, a hole or a groove communicating with the inside of the housing 5 may be formed in a part of the stem 26 so that gas can be filled without operating the stem 26.

In the above-described embodiment, the fluid is ejected when the stem 26 is operated upward in the drawing, but the fluid is not limited to ejected when the stem 26 is operated downward. Further, although the piston member 18 is pressed by the stem 26 when releasing the stopper 12, it is also possible to release the stopper 12 directly by the stem 26 by applying conventional means. Further, although an example in which one fluid container 17 is provided in the container body 1 has been shown, a design change such as arranging a plurality of fluid containers in parallel and communicating with each other through the pressure valves 19 is possible.

As described in detail above, the present invention applies relatively different biasing forces in opposite directions to the piston member inserted into the housing, and switches the biasing force by operating the stem to communicate with each container. By rapidly opening and closing the orifice, fluids in each container are mixed or shut off, so that many types of fluids can be accommodated in one container body. It can also be applied to things that need to be mixed in precise proportions, such as oxidizing agents and reducing agents, and can be rapidly discharged with compressed gas. It is easy to handle by simply manipulating the stem, and it has excellent effects such as being able to be used in products sold to general users and having a wide range of uses.
