ABSTRACT:
TECHNICAL FIELD
This invention relates to a mixing and discharge device that can simultaneously eject the contents out of a pair of containers, each equipped with a discharge nozzle, and can discharge both contents together.
BACKGROUND OF THE INVENTION
Official gazette of Japanese Patent Application (OPI) No. 102569/1992 disclosed a device of the type that discharges together two liquid chemicals, such as certain hair dye components. The aerosol containers contain the two liquid chemicals separately, and when in use, the device ejects the contents, i.e., the chemical agents, simultaneously from a pair of aerosol containers, discharges the mixed chemical agents together through a common hole, and applies the mixture onto hair of the head by means of a brush.
This device based on the prior-art technology comprises a pair of aerosol containers containing liquid chemicals; a bottomed container case for housing the two aerosol containers in a side-by-side position; a guide member equipped with two step holes, which are connected by a hinge in a manner that closes the top opening of this container case and into which the discharge nozzles of respective aerosol containers bump and are fitted from underside, a discharge port on the top surface, and passages for connecting the discharge port with both step holes; and a movable cover equipped with a depressible lever, which is suspended on the front side of the container case.
In this prior art, a depressible lever is pressed toward the container case with fingers of the hand holding the containers, and thereby the guide member is moved downward and tilted, with the hinged connection working as the axis. This movement makes the discharge nozzles on the pair of the aerosol containers depressed and opened simultaneously, and enables both liquid chemicals inside the aerosol containers to be sent through the step holes and the passages and discharged outside together through the discharge port. Thus, this prior art is highly effective because a simple depressing operation of a depressible lever allows the contents of the two aerosol containers to be discharged together simultaneously, in the integrally blended state in which they are useful, and to be applied by means of a brush.
However, this prior-art technology requires that a hinge connects the container case with the movable cover having the discharge port. The fitting structure is not simple, and there is a difference in the extent to which the discharge nozzles of respective aerosol containers are depressed because these discharge nozzles are opened by pressing down and tilting the movable cover through the action of the depressing force that is biased to one side. For this reason, this prior art has a problem in that there is a difference in the volumes of the contents discharged from the two aerosol containers and that the user may use the contents at an improper ratio, without recognizing this imbalance.
Similarly, because pressing down and tilting the movable cover opens the discharge nozzles of the aerosol containers, there was another problem in that it is difficult to secure the seal between the discharge nozzles and the step holes in the movable cover.
Furthermore, the depressible lever has a hard structure that does not undergo deflective deformation. Thus, the prior art has still another problem in that, since the hard depressible lever is located at a projected position in front of the containers, this projected lever disturbs the handling and storage of the containers.
Because of this hinge, the brush and the entire passages for discharging the contents cannot be separated easily from the attachment to the containers provided with discharge nozzles. Therefore, a problem arose in that the entire discharge passages and the brush could not be cleaned for the convenience of repeated use.
The discharge passage components comprise a movable cover and a guide member. From the configuration shown in the drawings, it is not considered easy to separate these two parts. Rather, it seems that the movable cover and the guide member are fixed to each other to obtain reliable sealing ability. Thus, the prior art had another problem in that even if the discharge passage components are separated from the attachment to the containers provided with discharge nozzles, it is hardly possible to clean the inside of the passages.
This invention has been made to solve the above-described problems found in prior art. A technical problem of this invention is that the device of this invention has a configuration ensuring that the portions with which to depress the discharge nozzles of aerosol containers, the containers of the pumping type, and the like, are pulled right downward by the operation of these portions with fingers of the hand holding the containers. Another technical problem of this invention is that the mixing and discharge device has a configuration that enables the components of the device to be easily disassembled. An object of this invention is thus to obtain a mixing and discharge device that can be used always properly and cleaned.
Still another technical problem is that the portions with which to depress the discharge nozzles can be displaced downward simply and stably. Another object of this invention is to obtain a mixing and discharge device that gives a stabilized posture to the portion for discharging the contents, secures strong, stable sealing performance, and has good, safe handling ability.
Still another technical problem of this invention is to give the device of this invention a structure capable of exposing the brush and the entire passages for discharging the contents from the containers of the aerosol type and the pumping type, provided with discharge nozzles. Still another object of this invention is thus to obtain a mixing and discharge device that enables the remaining contents to be fully washed away from the brush and the entire discharge passage components.
In an embodiment of the invention, the device comprises:
a pair of containers standing next to each other and respectively provided with a discharge nozzle having an open/close function;
an attachment, which is fitted firmly around the top portions of said containers and which comprises an elliptic cylinder to be fitted tightly around the top portions of the bodies of said pair of containers, a top inward brim disposed on the top edge of the elliptic cylinder, and an opening from which the discharge nozzles come out; and
a cap unit to be fitted detachably to the discharge nozzles and provided with a passage block, which comprises a pair of step holes disposed in the areas near both sides, into which the discharge nozzles are fitted tightly from underside, a discharge cylinder disposed at the center and on top of this unit to form a discharge port, and discharge passages for connecting this discharge port with the step holes,
wherein said mixing and discharge device also comprises: a pair of hanging plates (
51
) that comes out of the central, front and rear portions of the passage block (
17
) and hangs down on the front and rear walls of the elliptic cylinder (
27
); a pair of manipulating plates (
55
) extending from the lower end of either one of said hanging plates (
51
) or the elliptic cylinder (
27
); descendible projections (
16
), which are provided respectively with a guide slope (
16
a
) and disposed on the manipulating plates (
55
) at positions opposite to valley-shaped portions that are formed in abutment with the bodies of said pair of containers (
33
), with the tip of the guide slope (
16
a
) being set at a height under the lower end of said elliptic cylinder (
27
); and a pair of edges of contact (
57
) disposed at the other one of the hanging plates (
51
) or the elliptic cylinder (
27
) at positions opposite to said guide slopes (
16
a
), and wherein a force to pull down the cap unit (
8
) is actuated by depressing said manipulating plates (
55
) in the lateral direction and sliding said guide slopes (
16
a
) over the edges of contact (
57
).
