DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-liquid or multi-liquid discharging container which mixes and discharges two or many liquids separated during storage when used.

[0002]

2. Description of the Related Art Two-pack hair dyes and chemicals are used by separating and storing two contents liquids when not in use, and mixing and using the two contents liquids when in use. In order to mix these two liquids, the contents liquid such as each medicine is taken out on a tray or the like and mixed. However, in this case, there are inconveniences such as requiring a tray. Therefore, recently, each content liquid is separately filled in a separate aerosol container, and at the time of mixing, the content liquid is discharged from both containers at the same time through a common discharge hole, so that two or more liquids are discharged during the discharge.
A two-liquid discharge container that takes out the liquid while mixing the liquid is considered, or a two-liquid discharge container that discharges the liquid and mixes it on an applicator such as a comb is proposed.
No. 967, 1992 Patent Application Publication 102569, 1992 Utility Model Application Publication 135469, and 1995 Utility Model Application Publication 546). These conventional two-liquid discharge containers have a common communication hole for communicating the valve stems of the two aerosol containers and a joint cap that forms a discharge hole. The structure is such that the valve stems of the individual containers are simultaneously pushed down.

[0003]

[Problem to be solved] However, in the type in which the joint cap is pressed down by hand, it is not always easy to correctly press the center of the joint cap correctly so that the pressing pressure acts equally on the valve stems of both containers.
If the pressing pressures acting on the left and right valve stems become unequal, the discharge amounts and discharge states of both contents liquids become uneven, and a desired mixed contents liquid cannot be formed.

[0004] Further, in the type in which the joint cap is pushed down by a lever, the number of parts is increased by the amount of the lever, the structure becomes complicated, and the assembling process of the product becomes complicated. In addition, these aerosol containers have a cover cap that covers the joint cap to prevent dust from adhering to the discharge hole. In the case of the type that pushes down and the type in which the joint cap is pushed down with a lever, it is necessary to remove the cover cap first, so that the operation can not be performed with one hand and to prevent the removed cover cap from dissipating. Attention was required and it was inconvenient.

[0005] As a result, the joint cap can be correctly pushed so that the pushing pressure acts equally on the valve stems of both containers, and the number of parts increases, the structure becomes complicated, and the product becomes difficult. There is a demand for the development of a multi-liquid discharge container that does not complicate the assembling process and that can perform a depressing operation for taking out a content liquid without having to remove the cover cap.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and allows a joint cap to be correctly pushed so that a pressing force acts evenly on valve stems of both containers, thereby increasing the number of parts. Multi-liquid discharge container that can be pushed down for taking out the content liquid without complicating the structure, complicating the product assembling process, and without having to remove the cover cap The purpose is to provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings showing an embodiment. 1 and 2, reference numeral 1 denotes a two-liquid discharge container as an example of a multi-liquid discharge container. The two-liquid discharge container 1 has two aerosol cans 2, a bundling member 3, a joint cap 4, and a cover cap assembly 5.

The aerosol can 2 is filled with a viscous content liquid under an internal pressure and has a valve stem 6 projecting to the outside. When the valve stem 6 is pressed down, the content liquid is discharged through the valve stem 6. The aerosol can 2 having such a structure is conventionally known.

The two aerosol cans are erected in parallel, bound by a binding member 3 and their relative positions are fixed. As shown in FIGS. 1, 2, and 3, the bundling member 3
It consists of a base cup 7 and a shoulder cover 8. The base cup 7 is dish-shaped and has a bottom 11 of two aerosol cans 2.
The bottom portion 11 is received in a state in which the bottom portion 11 is tightly fitted to the body, and the relative positions of the bottom portions 11 of the two aerosol cans 2 are fixed. On the other hand, the shoulder cover 8 is provided with two annular fitting rings 13 connected by a connecting portion 14, and the shoulder portions 12 are tightly fitted to the respective fitting rings 13 with the shoulder portions 12 of the aerosol can 2. To fix the relative position of the two shoulders 12. In this way, the aerosol cans 2 are bundled at two places, the bottom part 11 and the shoulder part 12, and the relative positions are fixed.

A joint cap 4 is fitted to the upper end of the binding member 3 so as to be slidable. As shown in FIGS. 1, 2 and 4, the joint cap 4 communicates with two communication holes 15 formed in the vertical direction and a communication hole 16 formed in the horizontal direction for connecting the two communication holes 15. A discharge port 17 communicating with the center of the hole 16, and each of the guide holes 15 is attached to both or one of the two valve stems 6 while receiving the valve stem 6 one by one. I have. The communication hole 16 is formed by closing both ends of the through hole with plugs 18.
