Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to discharge a mixed liquid by putting a second agent from an auxiliary container into a container body containing the first agent and mixing the same, and forming a discharge port at the tip of the nozzle portion. The present invention relates to a mixed liquid container used while being allowed to move.

[0002]

2. Description of the Related Art For example, since a hair dye that is applied to hair to dye hair is a liquid cosmetic that generates gas by oxidation, it is composed of, for example, a redox agent. One agent and a second agent made of an oxidative hair dye are stored in separate containers made of, for example, a thermoplastic resin,
At the time of use, these are mixed to perform hair dyeing work. That is, the second agent contained in the auxiliary container is put into the mixing container containing the first agent and mixed, and the hair agent is applied to the hair from the nozzle portion provided in the mixing container for use.

In the conventional mixing container in which the first agent and the second agent are mixed and used, an encapsulating member such as an overcap is attached so that the mixed solution can be enclosed in the container during mixing. After the mixing is completed, these sealing members are removed and the mixed liquid is discharged from the nozzle portion.

A mixing container for containing a liquid mixture which produces a gas by mixing a first agent and a second agent such as a hair dye is liable to deteriorate the contents mixed with the passage of time.
In many cases, it is used as a disposable container, and the mixing container may be discarded or stored while being left inside without being used up. On the other hand, users tend to discard or store the mixing container after reattaching the encapsulating member so that the number of dust and parts does not increase, so the mixing container is discarded and stored in such a state. When this happens, the gas generated from the remaining mixture loses its escape and fills the inside of the container under pressure, and eventually the pressure causes the mixture container to rupture, causing the remaining mixture to scatter around. I will let you.

According to the present invention, it is possible to surely prevent the mixed solution remaining after use from being sealed inside, effectively avoid the scattering of the mixed solution due to the rupture of the container, and eliminate the need for an overcap or the like. An object of the present invention is to provide a mixed liquid container capable of reducing the cost.

SUMMARY OF THE INVENTION The present invention is a flexible container body for containing a first agent, a nozzle portion mounted on the neck of the container body, and an auxiliary for containing a second agent. A second container from the auxiliary container into the container body for mixing, and a thermoplastic resin used while discharging the mixed liquid by forming a discharge port at the tip of the nozzle portion. A container for liquids, wherein the mixed liquid generates gas by mixing a first agent and a second agent, and the tip of the nozzle portion is ruptured by pressing from a direction facing the tip portion. The above object is achieved by providing a container for mixed liquid in which a closing film that opens is provided and a pressing protrusion that breaks the closing film is provided in the cap portion of the auxiliary container.

In the operation of mixing the first agent and the second agent in the container body, the container body is shaken before the discharge port is formed at the tip of the nozzle portion attached to the neck of the container body. It is also possible to perform the mixing work by breaking the closing film at the tip of the nozzle portion to form the discharge port, and then pressing the discharge port with a finger or the like.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the mixed liquid container 10 of the present embodiment contains, for example, a redox agent that forms a hair dye as a first agent, a container body 11 to which a nozzle portion 12 is attached, and an oxidative dye. It is commercialized and sold in a state of being combined with an auxiliary container 20 that contains a hair material as a second agent.

That is, the mixed liquid container 10 of the present embodiment.
Is a container body 11 that is flexible and contains the redox agent.
And a nozzle portion 12 attached to the mouth portion of the container body 11.
And an auxiliary container 20 for accommodating the oxidative hair dye, and the oxidative hair dye is put into the container body 11 from the auxiliary container 20 and mixed, and a discharge port is formed at the tip of the nozzle portion 12 to form a mixed liquid. Is a container for a mixed liquid made of a thermoplastic resin used while discharging the hair dye. Further, according to the present embodiment, the hair dye which is a mixed liquid generates gas by mixing the redox agent and the oxidative hair dye, and the tip of the nozzle portion 12 faces the tip. A closing film 13 (see FIG. 2) that is torn and opened by pressing from the direction is provided, and a pressing protrusion 14 that breaks the closing film 13 has an auxiliary container 20.
It is provided on the cap portion 22.

According to the present embodiment, the container body 11 constituting the mixing container 10 is a blow molded product made of, for example, a single-layer or laminated polyethylene as a thermoplastic resin, and has flexibility. By pressing (squeezing) the torso portion, the hair dye can be discharged by discharging the hair dye from a discharge port formed at the tip of the nozzle portion 12 described later. A male screw ridge is formed on the mouth of the container body 11, and the base end skirt 15 of the nozzle 12 is detachably screwed.

Nozzle portion 12 constituting the mixing container 10
Is a base end skirt portion 15 and an elongated substantially conical discharge having a diameter of about 3 to 10 mm and protruding upward from the central portion of the ceiling surface of the base end skirt portion 15 by a length of, for example, about 20 to 50 mm. The nozzle 16 is an injection molded product made of polypropylene, for example. A female screw ridge is formed on the inner peripheral surface of the base end skirt portion 15, and the nozzle portion 1 is removed from the state in which the redox agent is enclosed in the container body 11.
2 is removed and the oxidative hair dye is put in from the auxiliary container 20, and then the nozzle portion 12 is screwed on again to enclose them,
The mixing operation of the redox agent and the oxidative hair dye can be easily performed by, for example, shaking the mixing container 10 vertically and horizontally. As shown in FIG. 2, the discharge nozzle 16 has a hollow interior and a discharge flow path 17 for a hair dye having a diameter of about 0.5 to 5 mm, which communicates with the opening of the neck of the container body 11. And a closing film 13 for blocking the discharge channel 17 and sealing the mixing container 10 until the mixing container 10 is used for hair dyeing work. Has been.

According to this embodiment, the closing film 13 is provided integrally with the nozzle portion 12 when the nozzle portion 12 is molded, and is located inside the end edge 18 of the discharge nozzle 16 forming the nozzle portion 12 (on the container body side). It is located in the discharge flow path 17 and is arranged, for example, about 0.5 to 5 mm away from the end edge 18. Further, as shown in FIG. 3, the closing film 13 has a circular plane shape with a diameter of, for example, about 0.5 to 5 mm and is provided with a thickness of about 0.1 to 1 mm. Further, according to the present embodiment, a plurality (six) of opening guide wires 19 extending in the radial direction from the center of the circular plane shape have, for example, cuts on the front surface or the back surface,
It is provided by reducing the thickness of the closing film 13 along the opening guide wire 19.

Since the closing film 13 is provided inside the discharge flow path 17 inside the end edge 18 of the nozzle portion 12, when the closing film 13 is broken and the discharge port is opened, It is possible to avoid the cut pieces of the closing membrane 13 from protruding outwardly from the edge 18, so that the nozzle portion 12
Even if the hair is dyed while the tip of the hair is in contact with the scalp, the work can be performed without damaging the scalp. Further, since the opening guide wire 19 is provided in the closing film 13, even if the closing film 13 is made of polypropylene having a considerable strength similar to that of the nozzle portion 12, the pressing protrusion 14 presses the closing film 13. When breaking, by smoothly extending the breaking line outward in the radial direction, it becomes possible to easily form an opening of a considerable size over substantially the entire discharge passage 17 having a narrow cross section. Further, even when the closing protrusion 13 cannot be sufficiently broken by the pressing protrusion 14, the breaking line can be extended and guided radially outward by the pressure from the inside when the hair dye is discharged, so that the opening can be greatly expanded. Become.

As shown in FIGS. 1 and 2, the auxiliary container 20 is a laminated blow-molded product made of a thermoplastic resin such as polyethylene and ethylene vinyl alcohol copolymer. A hair material is contained as a second agent. Further, a cap portion 22 is detachably screwed to the mouth portion of the main body portion 21 so that the oxidative hair dye material can be enclosed in the auxiliary container 20.

The cap portion 22 that is screwed into the main body portion 21 of the auxiliary container 20 is an injection molded product made of polypropylene, for example, and a female thread ridge is formed on the inner peripheral surface of the base end skirt portion 23. In addition, from the central portion of the ceiling plate 26 of the base end skirt portion 23 toward the outside, the length of the bottom portion is, for example, about 1.0 to 10 mm, and the diameter of the bottom portion is 0.
A pressing protrusion 14 having a conical portion 24 of about 5 to 5 mm at its tip is provided so as to project. Further, on the opposite side of the base end skirt portion 23 sandwiching the ceiling plate 26, an annular protection wall 25 extending in the same sectional shape as the base end skirt portion 23 is provided concentrically with the pressing protrusion 14. There is.
Since the protective wall 25 projects from the ceiling plate 26 with a length of, for example, about 1 to 15 mm, which is longer than the projecting length of the pressing projection 14, the pressing projection 14 having a sharp tip directly touches and damages the surrounding objects. There is no protection.

The protruding length of the pressing projection 14 provided on the cap portion 22 of the auxiliary container 20 and the mixed liquid container 10
The distance from the edge 18 of the nozzle portion 12 of the closing film 13 provided in the nozzle portion 12 of the
The pressing projection 1 until it contacts the ceiling plate 26 of the cap 22.
4 is inserted inside the tip of the discharge nozzle 16 to close the closing film 1.
It is appropriately set such that at least the bottom of the conical portion 24 of the pressing protrusion 14 has a length capable of penetrating the closure film 13 when breaking 3.

According to this embodiment, when the mixed liquid container 10 is used for hair dyeing work, for example, the nozzle portion 12 of the mixed liquid container 10 in which the redox agent is enclosed is removed, and the container is removed from the auxiliary container 20. The oxidative hair dye is put in the main body 11, the nozzle portion 12 is attached again, and the redox agent and the oxidative hair dye are mixed to form a hair dye. Then, as shown in FIG.
Using the empty auxiliary container 20 in which the cap portion 22 is reattached, the pressing protrusions 14 projecting to the outside of the cap portion 22 are arranged facing toward the tip of the nozzle portion 12, and the pressing protrusions 14 of the nozzle portion 12 are arranged. By inserting into the hollow portion of the tip portion and pressing the closing film 13 disposed therein, the closing film 13 is ruptured and plastically deformed, and the discharge passage 17 is discharged to the tip portion of the nozzle portion 12. The outlet is opened. As a result, the mixed liquid container 10 is gripped by the hand, the body portion of the container body 11 is pressed, and the hair dye, which is the liquid mixture, is discharged from the discharge port formed in the opening and applied to the hair. Will be able to do.

Even if the user interrupts the hair dyeing work by only mixing the redox agent and the oxidative hair dye in the container body 11, it is possible to prevent the container body 11 containing the mixture from bursting. In addition, after the oxidative hair dye is put into the container body 11 from the auxiliary container 20 and the nozzle portion 12 is attached, the closing film 13 is ruptured and the tip of the nozzle portion 12 is broken before shaking the container body 11 to perform mixing. It is also possible to form a discharge port in the above and perform mixing while closing the discharge port with a finger or the like. In addition, since the pressing protrusion 14 is provided on the cap portion 22 that is integrally mounted to the auxiliary container 20 having a certain size, the auxiliary container is broken when the closing film 13 is broken to form the discharge port. Due to the easiness of holding 20, it becomes possible to easily press the opening film 13 with a considerable force by the pressing protrusions 14, and even if the closing film 13 is made of polypropylene having strength, the discharge port can be easily opened. It becomes possible to form an opening.

Further, according to the present embodiment, the container body 1 to which the nozzle portion 12 constituting the mixed liquid container 10 is attached.
After using 1 for hair dyeing work, even if the hair dye still remains inside the container body 11, the hair dye was reliably prevented from being enclosed, and was discarded or stored after use. When
It is possible to effectively avoid scattering of the hair dye due to the rupture of the container body 11. That is, according to the present embodiment, the discharge port of the discharge flow path 17 is obtained by breaking and opening the closing film 13 with the pressing projection 14, and after breaking the closing film 13, the discharging port of the nozzle portion 12 is again opened. Since the user does not have any encapsulating member such as an overcap that closes and encloses the hair dye inside, the user cannot mistakenly reattach the encapsulating member to the container 10 and dispose of it. It is possible to reliably avoid the scattering of the hair dye due to the rupture of the main body 11. Further, according to the present embodiment, since the discharge flow passage 17 formed inside the elongated discharge nozzle 16 has a small cross-sectional area and is narrow, the container body 11 that has been discarded or stored while the hair dye remains, falls down. Even if it is turned upside down, it is possible to prevent the remaining hair dye from leaking out.

Further, according to the present embodiment, the closing film 13 and the pressing protrusion 14 for forming the discharge port are formed when the nozzle portion 12 of the mixed liquid container 10 or the cap portion 22 of the auxiliary container 20 is formed. Since it is formed integrally with these and does not require separate parts such as an overcap for opening and sealing, it is possible to easily reduce the cost and reduce the amount of dust generated. Become.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the mixture that generates gas by mixing the first agent and the second agent does not necessarily have to be a hair dye, but may be another mixture such as a perm agent or an adhesive. Further, the container body of the mixed liquid container may be a laminated release container or the like, and the auxiliary container containing the second agent does not necessarily have to be a container made of a thermoplastic resin.

According to the mixed solution container of the present invention, it is possible to reliably prevent the mixed solution remaining after use from being sealed inside, and effectively avoid the scattering of the mixed solution due to the rupture of the container. Further, the cost can be reduced by eliminating the need for an overcap or the like.
