[Detailed description of the invention]

[0001]

The present invention relates to a dispensing container, and in particular,
The present invention relates to a container for containing contents in which fine spheres that can be broken and contain a solvent are dispersed in a solution.

[0002]

2. Description of the Related Art Conventionally, when a solution-like substance, whether natural or chemical, is stored in a container, a temporal change may occur due to a chemical change such as polymerization.

[0003] In addition to changes in materials, deterioration or discoloration may occur due to ultraviolet rays from the outside, or the contents may be oxidized by oxygen in the air.

[0004] Further, in the case of natural fragrances and compounded fragrances which are mixtures of substances having different volatility, the contents may be partially changed due to volatilization of the volatile substances. In particular, a fragrance is usually added to a lotion or an emulsion, but in such a mixture, the above-mentioned various changes are likely to occur, so that various measures need to be taken.

In many cases, it is possible to suppress the chemical change of the contents by a chemical treatment, but in the course of developing a more effective product, the formulation must be liable to undergo chemical aging over time. May not be.

In order to put such a product into practical use, for example, when there are a first solution and a second solution which should be used at the same time but are inappropriate to be mixed, the first solution is used.
It is conceivable to disperse fine spheres (microcapsules) that can be broken and contain the second solution inside the solution. According to such a method, the reaction is avoided because the two do not come into direct contact with each other during storage, and the desired effect can be exerted by breaking and mixing the microspheres during use.

[0007]

[Problems to be Solved by the Invention] However, when such a method is adopted, it is necessary to break the fine spheres by taking the solution in which the fine sphere solution is dispersed, taking it on the palm of the hand, and crushing it at the time of use. However, there are insufficient aspects in terms of usability.

The present invention has been made in view of the above-mentioned problems, and contains contents in which a sphere capable of being broken and containing a solvent is dispersed is contained in a solution, and the sphere is broken in a container. It is a technical object of the present invention to provide a dispensing container capable of dispensing after mixing a solvent and a solution.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problems, the present invention provides a method for accommodating, in a solution, a content obtained by dispersing a microsphere 1 capable of being broken and containing a solvent therein. A container having the following configuration.

A squeeze container body 2 is provided with a mouthpiece 3, a cylindrical cylinder 4 is provided in the mouthpiece 3, and a check valve which opens at the container side end of the cylinder 4 in the direction of discharging the contents. 5
While providing, Roh nozzle serves the piston 6 a gas-liquid-tight manner slidably and irremovably from the cylinder 4 into the cylinder 4
And a crushing section 9 having a flow-through portion 8 smaller than the diameter of the fine sphere 1 at the inlet side of the injection hole 7.
Was provided.

As the crushing section 9, a porous plate or mesh is suitable.

[0012]

When the internal pressure of the container is increased by strongly pressing the squeeze container main body 2, the contents are pushed into the cylinder 4 by pushing the check valve 5 open. At the same time, the nozzle / piston 6 rises and a part of the nozzle / piston 6 is exposed to the outside.

Subsequently, when the nozzle / piston 6 is pushed into the cylinder 4, the pressure in the cylinder 4 increases, and the contents flow out of the pouring hole 7. At this time, the fine sphere 1 passes through the flow portion 8 having a smaller diameter than the diameter of the fine sphere 1 and is broken.

After the fine spheres are broken in the container as described above, the solvent and the solution can be mixed and poured out, so that it is not necessary to crush the fine spheres after pouring.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. The squeeze container main body 2 is made of a flexible synthetic resin, and accommodates therein a content in which microspheres 1 that can be broken and contain a solvent are dispersed in a solution.

The squeeze container body 2 is provided with a mouthpiece 3. A thread 3a is provided on the outer periphery of the mouthpiece portion 3, and the cap 20 is fitted on the thread 3a. A cylindrical cylinder 4 is provided in the mouthpiece portion 3.

The cylinder 4 is provided at one end of the cylindrical body with the mouthpiece 3
Is formed by forming a flange 4a that engages with the rim of the rim. Then, this cylinder 4, Roh nozzle combined piston 6, freely vapor liquid-tight slide, and the cylinder 4
It is internally fitted to undetachable.

The nozzle / piston 6 has an injection hole 7 formed at the center of the cylindrical body, and a skirt 6a is provided at the container side end of the nozzle / piston 6. This skirt 6
a is for improving airtightness. A slit 7a is provided on the tip side of the nozzle / piston 6. The slit 7a is provided in one character so as to cross the tip of the pouring hole 7, and is configured so that the pouring hole 7 is not closed even when the tip of the nozzle / piston 6 is pressed.

At the inlet side of the pouring hole 7, the fine sphere 1
A mesh finer than the diameter of the mesh is provided, and this mesh is the crushing portion 9. The crushing portion 9 may be any material such as a punching metal as long as it has a flow portion 8 having a diameter smaller than the diameter of the fine sphere 1.

A check valve 5 which opens in the direction of discharging the contents is arranged at the container side end of the cylinder 4. This check valve 5
Is formed of an elastic synthetic resin, and is hinged to a fixing portion 9 a fixed to the mouthpiece portion 3. This check valve 5 is normally urged in the closing direction, but the pressure from the inside of the container causes
As shown in FIG.

Next, the operation of the above configuration will be described. When the squeeze container body 2 is pushed strongly to increase the internal pressure, the contents push the check valve 5 open and flow into the cylinder 4. At the same time, the nozzle / piston 6 rises and the upper part of the nozzle / piston 6 is exposed to the outside (FIG. 2).

Subsequently, when the container is turned upside down and the nozzle / piston 6 is pushed into the cylinder 4 with a finger or palm (FIG. 3), the pressure in the cylinder 4 increases. Here, since the check valve 5 is closed, the contents flow out of the discharge hole 7 to the outside. At this time, the fine sphere 1 passes through the flow portion 8 having a smaller diameter than the diameter of the fine sphere 1 and is broken. Then, the solvent and the solution are mixed in the pouring hole 7.

The dispensed the contents can be smoothly dispensed to the outside through the slit 7a. As described above, after the fine spheres are broken in the container, the solvent and the solution can be mixed and poured out, so that the trouble of crushing the fine spheres after the pouring is unnecessary.

[0024]

As described above, according to the present invention, it is possible to accommodate the contents in which fine spheres are dispersed, to break the fine spheres in a container, and to pour out the mixed fine spheres.

In addition, since the pressure for breaking the fine sphere is obtained by pushing the piston serving also as the nozzle, a pressure higher than the pressure obtained by pressing the container is obtained, and the fine sphere can be easily broken.
