DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge container, and more particularly to a two-drain discharge container which discharges two contents of two containers individually from the tip of a nozzle without mixing them on the way.

[0002]

2. Description of the Related Art A pair of aerosol containers of this type are placed in the upper end of an outer cover for restraining the aerosol container adjacently in a manner in which the stem is hidden.
In a mode in which the orifice portion is protruded, a nozzle for individually discharging the two agents from the stem without being mixed on the way is dropped and mounted, and the nozzle is attached to the outer cover by a push-down lever having a pivot point secured to the stem. Japanese Patent Application Laid-Open No.
No. 9746.

That is, as shown in FIG. 10, a two-agent discharge container 1 is engaged with first and second containers 3 and 4 provided with stems 2a and 2b, and with stems 2a and 2b. A nozzle 5 that can move up and down with the nozzle 5
A cover 7 having insertion holes 6a and 6b for engaging the first and second stems 2a and 2b with each other,
And a lever 8 which comes into contact with the nozzle 5 and can push down the nozzle 5 and the stems 2a and 2b from above. The guiding path in the nozzle 5 is each container 3,
4 are divided by a partition plate 9 to individually guide the contents, and hanging cylinders 10a and 10b are suspended from the bottom surface for engagement with the stems 2a and 2b. This two-agent discharge container 1
Even if the cream-like hair dye becomes clogged inside the nozzle during use of the hair dye (the hair dye can exhibit the hair dyeing effect by mixing the first hair dye and the second hair dye). Therefore, it is necessary that the first agent and the second agent are simultaneously injected so as to maintain a certain ratio, but, for example, a hair dye and a propellant are mixed and injected in an aerosol container. In the agent discharge container, the injected hair dye becomes foamy (bubble), so there is almost no clogging in the nozzle. However, in the aerosol container, the creamy hair dye is injected In the two-agent discharge container configured to separate the agent through the inner bag, the hair dye in the form of a cream is injected as it is, so that the hair dye remaining without being ejected in the guide path of the nozzle The agent may be clogged.), Nozzle 5
Is engaged with the stems 2a and 2b from above the cover 7 through the insertion ports 6a and 6b, so that the nozzle 5 is taken out (pulled up) from the stems 2a and 2b and washed to obtain a creamy hair dye. Can be eliminated.

The above cleaning is performed as follows. That is,
The cleaning device 11 shown in FIG. 11 is used. The cleaning device 11
A pump unit capable of sucking and discharging a fluid such as water,
It is formed so that it can be attached to the hanging cylinders 10a and 10b of the nozzle,
And a flow passage 11b through which the fluid sucked and discharged by the pump portion 11a flows inside the nozzle 5.

The pump portion 11a has a bellows 12, and by expanding and contracting the bellows 12, water and the like can be sucked and discharged, and the fitting portion 13 is fitted at one end of the bellows 12 to the flow passage 11b. Can be done. Flow passage 11b
Is a fitting port 1 fitted to the fitting portion 13 of the pump portion 11a.
4 and a mounting port 15 which is bifurcated from the fitting port 14 and at which a hanging cylinder 10a, 10b of the nozzle 5 can be mounted at the tip thereof.
a, and a tube section 16 having 15b.

The cleaning method is as follows. First, the hanging cylinders 10a and 10b of the nozzle 5 removed from the two-agent discharge container 1 are cleaned.
With the mounting openings 15a and 15b.

[0007] The washing device 11 is immersed in water or the like together with the nozzle 5, and the bellows 12 is expanded and contracted so that water flows between the nozzle 5 and the washing device 11. In addition, bellows 1
Repeat the expansion and contraction of 2 several times. By using the cleaning device 11 to clean the nozzle 5, the cream-like hair dye clogged in the nozzle 5 can be completely removed without any trouble.

[0008] In order to enable a sufficient cleaning without relying on the cleaning device 11, examples of various configurations of the nozzles 5 are introduced as shown in FIGS. 12 and 13.

More specifically, FIGS. 10 and 13 show vertical division and horizontal division of the fitting method of the base 5a of the nozzle 5, and FIGS. 12a and b show vertical division and hinge division of the nozzle 5.
Horizontal division.

[0010]

However, the above-mentioned proposal of the deployable configuration has the following disadvantages.

The base 5a of the nozzle 5 is a so-called closed space pool for storing the injection of the contents from the stems 2a and 2b.
Although the internal pressure is high, the sealing effect of the configuration cannot be expected due to the simple butting of the ring-shaped divided portions of the closed space.

That is, under the premise of split expansion,
In the case of FIG. 10, the seal failure is apparent due to the mere abutment between the ring cuts, and FIG.
Unlike the case of FIG. 10, although there is an advantage that the pressing force of the lever 8 works, the poorness of the lap seal portion is not complemented by this.

FIG. 12A is exactly the same as that of FIG. 10 described above, and FIG. 12B is exactly the same as that of FIG. 13 described above.

The recovery of the nozzle 5 is carried out by removing the nozzle 5 from the recess of the cover 7 after removing the interference of the lever 8, which is extremely troublesome.

The present invention has been made in view of the above circumstances, and has as its object to rationally ensure a sealing effect of a nozzle base which is divided so as to be deployable for cleaning,
It is still another object of the present invention to provide a two-agent discharging device for individually discharging two contents of two containers that can be quickly taken out of a nozzle.

[0016]

In order to achieve the above object, a two-part discharge container according to the present invention is provided with an orifice portion in the upper end of an exterior cover for restraining a pair of aerosol containers adjacently in a manner in which their stems are hidden. When two nozzles from the stem are ejected individually without being mixed on the way in a protruding mode, the nozzle is dropped and mounted, and the nozzle is pressed against the stem by a push-down lever securing a pivot point on the exterior cover. In the two-agent discharge container described above, the above-mentioned nozzle is hinged to the upper half having an orifice portion and a partition plate at the rear edge of the nozzle base bottom, and the nozzle base bottom is raised into an inner rib shape. The partition plate fitting groove and the hanging tube for the stem are disposed in the raised portion, and the seal function is expandable and the sealing action when not expanded is ensured by a plug effect. .

Furthermore, by taking out a hanging arm provided with an undercut at the tip from the lever and holding and integrating the nozzle, the nozzle can be easily taken out by turning the lever.

[0018]

The rise of the inner rib at the bottom of the nozzle base acts like a plug to seal the opening in the upper half of the nozzle having the partition plate.

This sealing effect is of a completely different quality from the seal obtained by abutting the ring-shaped openings in a closed space.

When the nozzle integrated with the lever is taken out, it is convenient that the nozzle can be lifted to an exposed position where it can be easily taken out by turning the lever.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.
