Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container for accommodating crushable microcapsules containing a material such as cosmetics therein together with a liquid.

[0002]

[Prior art]

 In a two-liquid mixing type fragrance or cosmetic such as an antiperspirant, one of the liquid agents is filled in a microcapsule and housed in a container, and the other liquid agent is filled around the microcapsule in the container. A technique is being considered in which the microcapsules are crushed at the time of use and the two liquids are mixed.

In this type of container, it is necessary to crush the microcapsules by applying pressure to the microcapsules in some form when the content liquid is poured out.

[0004]

[Problems to be solved by the device]

 By the way, many of the microcapsules filled in such a container are minute, but depending on the material to be contained, the diameter of the microcapsules may be several millimeters.

For example, in a cosmetic that is used a large amount once, a large microcapsule is used in the container, but it is difficult to break such a large microcapsule only by pressure. There was such a problem.

Therefore, in the container filled with these two-liquid mixing type fragrances, the microcapsules are not properly crushed during use, so that the contents are poured or ejected out of the container while the two liquids are not sufficiently mixed. There was a problem that it would be done.

The present invention has been made in view of the above problems, and provides a container provided with a dedicated mechanism for crushing a microcapsule having a relatively large size, which enables reliable crushing of microcapsules during use. The object is to provide a simple container structure.

[0008]

[Means for Solving the Problems]

 The present invention is a container for pouring out the microcapsules 6 contained in the container body 2 together with the content liquid in the container body 2 through a pump portion 14 attached to the mouth portion 3 of the container body 2. did.

That is, the present invention constitutes the pump 4 a, and the cylinder 10 in which the opening 8 for sucking the content liquid is inserted into the internal space 5 of the container body 2, and the opening of the cylinder 10. 8 and a suction pipe 1 having a communication space 11 communicating therewith. Then, in the communication space 11 of the suction tube 1, a needle body 12 having a pointed portion directed toward the inner space 5, and a truncated portion provided around the needle body 12 in the direction of the inner space 5. And a blade body 13 pointing to.

[0010]

[Action]

 By operating the pump unit 14, the content liquid is sucked from the suction pipe 1 into the cylinder 10. At this time, the microcapsules 6 enter the communication space 11 together with the content liquid. Since the needle body 12 and the blade body 13 are provided in the communication space 11, first, the outer skin portion of the microcapsule 6 is destroyed by the tip of the needle body 12. Then, the outer skin portion of the microcapsule 6 is completely crushed by the blade body 13 provided around the needle body 12, and the material in the microcapsule 6 is scattered into the cylinder 10. As a result, the content liquid in the cylinder 10 and the raw material are mixed, and the mixed liquid is poured out to the outside.

The needle body 12 may be supported in the communication space 11 of the suction pipe 1 at the center of the space by the blade body 13 provided on the inner peripheral surface 16. That is, the blade body 13 also serves as a support member for the needle body 12, whereby the microcapsules 6 can be crushed more reliably with a small number of parts.

Further, the needle body 12 and the blade body 13 may be molded integrally with the main body of the suction tube 1 from plastic or the like. Further, the suction tube 1 has a structure that is attachable to and detachable from the cylinder 10, so that an optimum one for the diameter of the microcapsule 6 to be housed can be used. At this time, even if the passage space 7 or the opening 8 of the cylinder 10 is smaller than the diameter of the microcapsule 6, only the diameter of the communication space 11 of the adapter needs to be larger than the diameter of the microcapsule 6.

[0013]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional view showing a microcapsule storage container of the present invention.

As shown in FIG. 1, the microcapsule container of the present invention has a nozzle head 4, and a pump portion 14 for generating a pumping action by pushing down the nozzle head 4 has a mouth portion 3 of a container body 2. It is fixed to the screw cylinder. A pouring nozzle 15 is provided on the side of the nozzle head 4.

The pump unit 14 has a cylinder 10. The cylinder 10 has a passage space 7 therein, and a piston (not shown) is vertically movable in the passage space 7. This piston is biased in the upward direction by a spring (not shown). An opening 8 is formed at the lower end of the cylinder 10, and the end enters the internal space 5 of the container body 2. Also, a check valve (not shown) is provided in the cylinder to realize the pump mechanism. A known pump mechanism can be used.

A suction tube 1 is attached to the lower end of the opening of the cylinder 10. The suction pipe 1 has a communication space 11 inside, and its base end portion has an inner diameter substantially the same as the outer diameter of the cylinder 10 so that it can be fitted into the tip portion of the cylinder 10. . Moreover, the inner diameter of the tip portion is processed into a reverse taper shape in which the diameter of the communication space 11 gradually increases, and it becomes easy to store the microcapsules 6 housed in the inner space 5 of the container body 2 in the communication space 11. ing.

A blade body 13 is formed so as to project in the radial direction from four points on the inner peripheral surface 16 of the communication space 11 of the suction pipe 1 toward the center thereof, and these four blade bodies 13 are formed at the center thereof. The needle body 12 provided in the axial direction is supported at the side tip. The tip of the blade body 13 on the inner space 5 side is formed into a truncated shape. Further, the tip of the needle body 12 on the inner space 5 side is formed in a pointed shape.

In the present embodiment, the main body of the suction tube 1, the blade body 13, and the needle body 12 are all formed of hard plastic having an integral structure, but the needle body 12 and the blade body 13 are made of metal or the like. The structure may be formed by another member and fitted into the communication space 11.

As the suction tube 1, it is possible to prepare a plurality of suction tubes 1 having different diameters of the communication space 11, and the kind of the suction tube 1 may be changed depending on the diameter of the microcapsule 6 accommodated therein. . In this case, only the suction tube 1 needs to be replaced even if the microcapsule 6 to be stored is changed, and the container body 2 and the pump portion 14 can be used for general purposes.

In addition, if the diameter of the communication space 11 of the suction tube 1 is made sufficiently large, the microcapsule 6 will be crushed at the stage of passing through the suction tube 1 during use, so that the opening of the cylinder 10 is opened. Even if the diameter of the portion 8 is small, the microcapsule 6 having a diameter larger than this can be used. The size of the microcapsule has a large diameter on the order of millimeters.

In the case of using the microcapsule-containing container of the present embodiment, when the container head 2 is gripped and the nozzle head 4 is pushed down and then the head 4 is released, the piston rises by the spring. At that time, the inside of the cylinder becomes negative pressure. As a result, the liquid in the internal space 5 of the container body 2 and the microcapsules are sucked into the suction tube 1. When the microcapsule 6 passes through the communication space 11 of the suction tube 1, a part of the outer skin of the microcapsule 6 is first destroyed by the tip of the needle body 12. Furthermore, the outer skin of the microcapsule 6 is finely crushed by the blade 13 provided around the needle body 12. By this series of processing, the material in the microcapsule 6 is mixed with the content liquid. Then, when the head 4 is pushed again, the inside of the cylinder is pressurized by shutting off the communication space by the check valve, and the mixed material in the cylinder 10 is discharged to the outside through the discharging nozzle 15. Since the outer shell of the microcapsule 6 is crushed into smaller pieces, it does not get stuck in the internal passage of the pump portion 14.

In the present embodiment, the suction pipe 1 is described as a detachable structure with respect to the cylinder 10, but the cylinder 10 and the suction pipe 1 may be integrated.
