Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention comprises a pair of aerosol containers restrained in a juxtaposed state and a discharge head attached to the top of the containers, and accommodates the aerosol containers. The present invention relates to a two-component mixing and discharging container for simultaneously discharging discharged contents from one nozzle. [0002] Conventionally, hair dyes and the like have been known as a mixture of two kinds of liquid preparations. For example,
In the case of a hair dye, the hair dye first agent and the hair dye second agent enclosed in separate containers are mixed in an applicator or on a tray so that the hair dye effect can be exhibited, and then the hair is dyed. Is generally performed. However, there is a restriction that it takes time and effort to perform the mixing operation and that it must be applied to the hair immediately after mixing. In order to save such troubles, for example, Japanese Patent Laid-Open No.
2. Description of the Related Art A two-component mixing and discharging container as described in 00-109150 is known. As shown in FIG. 8, this two-part mixture discharge container has two aerosol containers provided with stems, a hollow cylindrical cover 110 which is detachably engaged with a connector of both aerosol containers, and Hollow tubular cover 110
A nozzle 120 and an operation unit 130 sequentially housed therein. [0004] The nozzle 120 engages with the stems of both aerosol containers, and the cover 1 is vertically movable together with the stems.
It is housed within 10. To be precise, it is housed in a space defined by a nozzle sliding piece 114 provided on the inner wall of the cover 110. However, a sliding limited band 113 for limiting the sliding range of the nozzle 120 is provided around the inside of the hollow cylindrical cover 110 so as not to fall down. On the other hand, the operating section 130 has a pair of first projecting pieces 137 on both sides thereof, and this is formed by a vertical slit 115 provided on both inner walls of the hollow cylindrical cover 110.
By being fitted inside, it is fixed to the cover 110. In addition, the operating portion 130 is formed with a substrate portion 131 of the operating lever 136 in a cut-out shape while leaving the hinge portion 132. In order to strengthen the attachment so that the hinge portion is not displaced up and down when the operation lever 136 is pushed, the notch fitting portion 135 of the operating portion 130 has a second protrusion 1
38 are provided, and these are fitted into small holes 116 provided on the cover 110 side. Then, the entire operation unit 130 is fixed to the cover 110 with an adhesive. When the operation lever 136 is pressed down by a finger, two semicircular protrusions 139 formed on the back surface of the substrate portion 131 push the upper surface of the nozzle 120,
Accordingly, the stems of both aerosol containers are pushed down, and the first hair dye and the second hair dye are removed from both aerosol containers.
The agent enters the nozzle 120 via the introduction part 123 and is simultaneously ejected through guide paths formed in the nozzle base 121 and the nose part 122. According to the two-component mixing / discharging container having such a configuration, for example, the two components can be simultaneously discharged while being mixed on a brush, so that the hair dyeing operation can be performed quickly without the need for mixing. However, in the structure of the conventional two-part mixing / discharge container, the cover 110 can be removed by operating the detachable operation part 117, but the nozzle 120 is taken out from the cover 110. It is not possible. That is, the downward movement of the nozzle 120 in the cover 110 is restricted by the slide-limited band 113, and the operation unit 130 firmly fixed to the cover 110 also exists above the nozzle 120. Since the upward movement is prevented, the nozzle 120 cannot be taken out. In addition, the nozzle 120 itself is formed in a hollow shape by an adhesive and has a structure that cannot be separated. For this reason, there is an inconvenience that the nozzle 120 itself cannot be separated and the mixed liquid remaining inside cannot be washed. In view of this, the present inventor has separately proposed a two-part mixing / discharging container capable of taking out the nozzle and separating and cleaning the inside. This consists of a connector that restrains a pair of aerosol containers in a juxtaposed state, a nozzle with a guide path that mixes the contents discharged from the stems of both containers and simultaneously ejects them from the nose, and raises the nozzle upward. A two-part mixing / ejection container provided with a cover that is detachably engaged with the connector while being covered from above, and an operation lever that can press down the nozzle from above.
The nozzle is vertically movable and removably stored in a storage space formed in the cover, and the nozzle is divided into an upper nozzle piece and a lower nozzle piece so that the inside can be cleaned, and the operation lever is provided with the operation lever of the nozzle. This is a configuration in which a device is provided as a separate member in a recess at the top of the cover that is not provided. According to this, the nozzle can be taken out of the cover, and the inside can be easily cleaned by separating the nozzle. However, in the case of this two-part mixing and discharging container, the nozzle is made a member that can be taken out independently, and the nozzle is divided into two independent members, an upper nozzle piece and a lower nozzle piece, so that the inside can be cleaned. Therefore, when cleaning is necessary, the cleaning member is divided into four members, namely, a cover, an upper nozzle piece, a lower nozzle piece, and an operation lever. Therefore, it is conceivable that there are difficulties in the operability of disassembly and reassembly, such as management so that each part is not lost, and an increase in the number of combinations that need to be understood and stored in the order of assembly of each part. . An object of the present invention is to solve the above-mentioned problems and to provide a two-part mixture discharge container which has a structure capable of cleaning the inside of the nozzle and has excellent operability in disassembly and reassembly. . [0012] In order to achieve the above object, a two-part mixing and discharging container according to the present invention comprises a first aerosol container and a second aerosol container provided with a stem, and both containers arranged side by side. And a cover that detachably engages with the outer periphery of the connector, the nozzle being divided into two parts, an upper nozzle piece and a lower nozzle piece. A cover in which a stem push plate and a hinge portion are formed by slits in a bottom plate portion in the concave portion, and the stem push plate is used as a lid of the nozzle and the lower nozzle piece is carried thereon, The upper nozzle piece is provided with an operating portion which is continuous with the upper nozzle piece, and an operating lever which is swingable around the hinge portion is provided. While swinging around the nozzle part and pressing the stem, the contents discharged from both containers through the stem are guided into the nozzle and mixed from one discharge port so that they can be ejected simultaneously, while the nozzle is made to have the upper nozzle piece and It is characterized in that the inside can be cleaned by separating it into lower nozzle pieces. According to the two-part mixing and discharging container of the present invention, the nozzle is divided into an upper nozzle piece and a lower nozzle piece, but the lower nozzle piece is a stem push plate on the cover side as a nozzle lid. The upper nozzle piece is provided on the operation lever side. Therefore, the entirety can be divided into two parts simply by releasing the fit between the upper nozzle piece and the lower nozzle piece, and the nozzle can be separated vertically so that the liquid agent remaining inside can be washed. Also, as compared to a case where the interior is washable by making the nozzle an independent member that can be separated from the cover and the nozzle itself can be divided into an upper nozzle piece and a lower nozzle piece, the disassembling and assembling work of the washing is performed. The number of parts that are separated during operation is reduced, and the cover, upper nozzle piece, lower nozzle piece, and operation lever
The number of members is reduced to two members, one member of the cover and the upper nozzle piece, and one member of the lower nozzle piece and the operation lever.
Therefore, when disassembling and assembling, each part must be managed so as not to be lost, and the number of combined parts that must be memorized and memorized in the order of assembling each part is drastically reduced. Work operability is improved. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the illustrated embodiments.

First, as shown in FIG. 7, the cover 30 is removed from the connecting tool 10 by pushing the attaching / detaching operation portion 33 of the cover 30 inward from both sides. That is, when the attachment / detachment operation portion 33 of the cover 30 is pushed in the direction of the arrow, the lower end thereof is inclined on the inclined surface 1
6a, and is guided upward along the inclined surface 16a. For this reason, a force for pulling up the entire cover 30 is applied, and the engagement protrusion 32 at the lower end of the cover is moved to the engagement protrusion 1.
5 from above to below, and the cover 30
It is in a state where it has been removed from 0. Next, the lower nozzle piece 22 is connected to the upper nozzle piece 2
Extract from 1 and separate them. The lower nozzle piece 22 is loosely inserted into the upper nozzle piece 21 and is simply retained by the return force due to the elastic deformation of the guide path forming members 25a, 25b, so that the lower nozzle piece 22 can be easily separated without using any special tool. be able to. Therefore, the nozzle 20 can be easily cleaned while being separated into the upper nozzle piece 21 and the lower nozzle piece 22. After the cleaning, the nozzle 20 is loosely fitted with the lower nozzle piece 22 and the upper nozzle piece 21 to be integrated, whereby the nozzle 20 is set in the recess 36 of the cover 30 again. Then, by attaching the cover 30 assembled in this way to the connecting tool 10 again, the state returns to a state where it can be used as a two-component mixing and discharging container. In the above disassembly and cleaning operation for cleaning, the operation lever 40 and the upper nozzle piece 21 are integrated,
The stem push plate 39 and the lower nozzle piece 22 are also covered by the cover 3.
Since these two points are integrated with the discharge head 0 and are in a separated state among the components of the ejection head, disassembly and reassembly work for cleaning is very easy. That is, compared to the case where the ejection head is disassembled into three or more parts,
There is no difficulty in understanding and remembering the procedure of the reassembly operation, and there is little need to take care to not lose disassembled parts. As described above, according to the two-part mixing / ejection container of the present invention, the nozzle is divided into an upper nozzle piece and a lower nozzle piece, and the lower nozzle piece is provided with the nozzle lid. The upper nozzle piece is integrally provided on the operation lever side so as to be also used as a body and is integrally supported on the stem pushing plate on the cover side, and also as a substrate part of the operation lever. Therefore,
By simply releasing the fit between the upper nozzle piece and the lower nozzle piece, the ejection head can be disassembled at the same time, and the nozzle can be separated vertically and the liquid agent remaining inside can be washed.
In addition, the structure of the disassembly and disassembly for cleaning is compared to a structure in which the nozzle can be separated from the cover and the nozzle itself can be divided into an upper nozzle piece and a lower nozzle piece so that the inside can be cleaned. The number of parts that are separated during the process can be reduced, and the components of the ejection head are
The four members of the cover, the upper nozzle piece, the lower nozzle piece, and the operation lever are reduced to two members, one member of the cover and the upper nozzle piece, and one member of the lower nozzle piece and the operation lever. Accordingly, the number of parts that must be managed so that each part is not lost or that the assembly order of each part must be understood and stored is drastically reduced, and the operability of disassembly and reassembly for cleaning is improved.
