[Prior art]

As a two-liquid mixing container, for example, as shown in Japanese Patent Application Laid-Open No. H11-198975, two aerosol cans filled with different liquids are juxtaposed on the left and right sides and integrated with a connecting member. To the upper part of the liquid ejecting stem that rises through the top wall of each aerosol can and fits a leg tube vertically extending from the lower surface on both left and right sides to provide a press-down head with a nozzle. There is a known configuration in which two liquids of approximately equal amounts are mixed and ejected by lowering.

[0003] However, for example, in the case of a lotion or a gray hair dye, it may be desired to finely adjust the mixing ratio of the two liquids according to the condition of the user's skin or hair. After taking out the two liquids in an amount, it is desirable that only one required liquid can be selected and taken out.

[0004] As a measure for enabling the selection of the unloading operation, first, in the above-mentioned container, instead of the pressing heads connected to both stems, a pressing head with a normal nozzle is provided for each stem. It is conceivable that both the press-down heads are simultaneously pressed during the two-liquid jetting operation, and only the corresponding one-pressing head is pressed down with a finger or the like during the one-liquid jetting operation. However, only by this, in the above-mentioned two-liquid ejection, for example, the force applied to the finger applied to each of the press-down heads causes uneven pressing force to each of the press-down heads. The jetting amount of the ink tends to vary.

In view of the above, the present invention relates to a push-down plate in which two single containers having a push-down head attached to the upper end of a stem are connected to each other and placed on the inner side in the left-right direction of the upper surfaces of the push-down heads. A lowering member is provided between the two containers so that the leg portion hanging down from the lower surface of the container can move up and down and cannot be pulled out upward. By pressing down the upper surface of the pressing plate, an equal amount of the two liquids is ejected. And a two-liquid mixing / selection-type jet that is configured so that one liquid can be selected and jetted by pressing down the upper surface of one of the press-down heads exposed to the outside of the press-down plate. It is intended to provide a container.

FIG. 9 shows a third embodiment of the present invention. This embodiment is the same as the liquid passage in the second embodiment.
12 is formed linearly from the upper end of the stem 2 to the ejection nozzle 11.

[0028]

The present invention is configured as described above, and according to the first aspect of the present invention, the following effects can be obtained. In the container of the present application, a pressing plate 42 is placed on the upper surface of the pressing heads 3, 3 of the pair of left and right single containers 1, 1 integrally bound by the connecting member 21, and on the upper surface in the left-right direction. Since the pressing member 41 is provided so that the leg portion 43 hanging down from the lower surface of the pressing plate is vertically movable into the locking hole portion 28 of the connecting member 21 and cannot be pulled out upward, the pressing member 41 is pressed down. The pressing down of both press-down heads 3 and 3 can be performed simultaneously.
42 By pressing down the upper part of the pressing head that is exposed to the outside, the pressing head can be individually pressed down, and therefore, by each of the pressing operations, two liquids can be easily ejected simultaneously, or , Only the required one liquid can be selectively ejected. As described above, since the pressing member 41 has the pressing plate 42 placed on the upper surface of the middle part in the left-right direction of the pressing heads 3, 3, the pressing of the pressing heads 3, 3, Can be almost uniformly depressed, and there is no possibility that the ejection amount of the two liquids will vary, for example, when a finger is pressed down on each of the pressing heads.

Further, according to the second aspect of the present invention, the locking hole-shaped portion 28 has an elongated hole formed in the base plate 22 of the connecting member 21 so as to be elongated in the front-rear direction. A wide front and rear plate portion is inserted into the elongated hole, and retaining protrusions 46, 46 protruding from both front and rear surfaces of the plate portion are formed so as to be engageable with the lower surface of the substrate 22. Therefore, the locking hole 28 and the leg 43 can be formed compactly in a small gap between the two single containers 1, 1 and the container of the present application can be prevented from becoming bulky.

According to the third aspect of the present invention, vertical grooves 13, 13 which are open on both upper and lower sides are respectively formed in the front-rear intermediate portion of the opposing surfaces 10a of the press-down heads 3, 3. The left and right half-plate thick portions of the upper half of the leg portion 43 were slidably fitted in the two vertical grooves, respectively. 13 By sliding the inner surface and the outer surface of the half-plate thick portion, the pressing head 3 can be prevented from swinging in the front-rear direction together with the stem 2. The frictional resistance can be prevented from occurring during the operation.

According to the fourth aspect of the invention, the following effects can be obtained. ○ Virtual extension lines A, A obtained by extending the hole axes of the ejection nozzles 11, 11
However, since the two depressing heads 3 and 3 are provided so as to intersect with each other, the two liquids can be easily mixed by, for example, ejecting the two liquids onto the open palm at the intersection. A first flow path portion 12a extending inward in the left-right direction from the upper end of the stem, and a second flow path portion 12b extending from the first flow path portion to the left-right inward portion of the front surface of both press-down heads. Since the liquid flow paths 12 and 12 are provided, the angle θ ₁ formed by the virtual extension lines A and A of the discharge nozzle 11 opening at the end of the second flow path portion is reduced, so that the discharge from each discharge nozzle When the flow mixes, it is possible to prevent the splatters from splashing around.
