  1 includes a first container 1 filled with a first content A and a second container 2 filled with a second content B. As shown in FIG. The barrels of the first container 1 and the second container 2 are connected in parallel by a shrink film 3. A discharge member 4 is mounted on the top of the first container 1 and the second container 2. Further, a holding cap 5 is attached to the lower end of the second container 2.

As shown in FIG. 3, the first container 1 is a conventionally known double aerosol container, and includes a container body 6, an inner bag 7 accommodated in the container body 6, and upper openings of the container body and the inner bag. And a valve assembly 8 for closing the valve.
As shown in FIG. 4, the container main body 6 has a conventionally known form, and a metal plate is formed into a bottomed cylindrical shape having a barrel portion 6a and a bottom portion 6b, and a substantially conical shoulder at the upper end of the barrel portion. 6c is formed, an annular recess 6d is formed at the upper end of the shoulder, and a cylindrical opening 6e extending upward from the recess 6d is provided. Aluminum, tinplate, etc. are used as the metal plate. A one-piece can, a two-piece can, or a three-piece can may be used as the first container 1. The inner surface of the container body 6 of the first container 1 is provided with a coating film or coating made of synthetic resin.
The inner bag 7 is made of a synthetic resin having a bottom portion 7a, a cylindrical trunk portion 7b, a neck portion 7c provided at the upper end of the trunk portion, and a cylindrical opening portion 7d provided at the upper end of the neck portion. Examples of the synthetic resin include polyethylene, polypropylene, ethylene / vinyl alcohol copolymer, nylon, and laminates thereof.
A valve assembly 8 is attached to the openings 6e and 7d of the container body and the inner bag, and the lower end of the mounting cap 8b is fitted into the recess 6d of the container body. Reference numeral 8 a denotes a stem extending from the valve assembly 8. When the contents are discharged in the form of foam, the inner bag is filled with the stock solution and the propellant, and the inner bag is not filled with the cream or gel. Fill the space between the bags with a pressure agent such as nitrogen gas.

Returning to FIG. 3, the second container 2 is a single-layer aerosol container in which a stock solution and a propellant are filled together, and a valve body for closing the upper opening of the container body 9 made of synthetic resin. The assembly 10 is comprised.
As shown in FIG. 5, the container body 9 of the second container 2 includes a bottom portion 9a, a cylindrical trunk portion 9b, a shoulder portion 9c whose diameter is reduced upward from the upper portion of the trunk portion 9b, and the shoulder portion 9c. A cylindrical neck portion 9d extending upward from the top of the neck portion and a mouth portion 9e extending outward from the upper end of the neck portion 9d. The mouth portion 9e has a mouth portion side surface 9f and a planar mouth portion upper surface 9g on the upper surface of the mouth portion, and the mouth portion upper surface 9g has an annular shape for enhancing the sealing performance with the gasket of the valve assembly. The rib 9h is provided. Further, the bottom portion 9a is provided with a leg portion 9i so that it can stand on its own. In addition, as shown in FIG. 3, the bottom may be hemispherical, and the holding cap 5 (see FIG. 3) may be engaged with the spherical portion so as to be able to stand on its own.
The container body 9 is molded by injection blow molding using a synthetic resin such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), or nylon (NY). Since the said container main body 9 has translucency, the contents filled inside can be confirmed visually. Furthermore, even a content that easily corrodes a metal such as a hair dye can be stably stored without being corroded. Further, a synthetic resin container may be used as the first container. For example, when the content is a two-component hair dye, a nylon container body is used for the first container, and the second container is used. It is preferable to use a container body made of polyethylene terephthalate and fill the first container with an alkaline agent containing a dye and the second container with an acidic two agent containing an oxidizing agent. Furthermore, for the reason that the shrink film 4 (see FIG. 1) can be uniformly coated, it is preferable that the outer diameters of the body portions of the first container 1 and the second container 2 are substantially the same.

  As shown in FIG. 6, the valve assembly 10 holds a valve mechanism 15 and a gasket 16 disposed on the upper surface 9g (see FIG. 5) of the mouth of the container body 9 while holding the valve mechanism 15 and the housing 14 of the valve mechanism 15. And a mounting cap 17 fixed to the mouth portion 9e (see FIG. 5) so as to be compressed. The valve mechanism 15 includes a stem 11, a stem rubber 12, a spring 13, and a housing 14 for housing them.

  The stem 11 is composed of a cylindrical portion 11a provided on the upper side and a block-like columnar portion 11b provided on the lower side. Between the cylindrical part 11a and the cylindrical part 11b, a stem hole 11c communicating with the passage in the cylindrical part 11a is formed. The stem 11 is urged upward by a spring 13, and the upper surface 11d of the cylindrical portion 11b presses upward from the lower surface of the stem rubber 12 to always seal the stem hole 11c.

  FIG. 7 a shows another embodiment of the valve mechanism of the second container 2. In addition, the same code | symbol is attached | subjected to the same part as the valve mechanism 15 (refer FIG. 4) mentioned above, and the description is abbreviate | omitted. The valve mechanism 15a shown in FIG. 7A includes a housing 18 and a housing holder 19 that holds the housing 18. The housing 18 includes a cylindrical portion 11b of the stem 11 and a storage portion 18a in which the spring 13 is stored. The housing 18a extends outward from the upper end of the storage portion 18a, and fits downward at a substantially right angle at the tip. A piece 18b is provided. An introduction side hole 18c communicating with the inside of the second container is formed in the side wall of the storage portion 18a, and the second content B is guided into the stem 11 through the introduction side hole 18c. The housing holding body 19 has a cover portion 19a formed with a through-hole penetrating the stem 11 in the center, a housing holding portion 19b extending downward from the vicinity of the periphery thereof and pushed into the opening of the mouth portion 9e of the second container 9. The flange portion 19c extends further outward from the side edge of the cover portion 19a. An inward projecting piece 19d is provided at the lower end of the housing holding portion 19b.

  The housing 18 is pushed from below the housing holding portion 19b by bending the protruding piece 19d of the housing holding body 19 outward. When the housing 18 is housed inside the housing holding portion 19b, the bent projecting piece 19d returns to its original state by its elasticity and is disposed at the lower end of the fitting piece 18b of the housing 18. As a result, the housing 18 is held inside the housing holding portion 19 b of the housing holding body 19. The flange 19c of the housing holder 19 is disposed on the upper surface 9g of the mouth of the second container 9 via the gasket 16, and is caulked by the mounting cap 17 from above. The housing holding portion 19b of the housing holding body 19 is compressed and bent inward together with the vicinity of the mouth portion 9e of the second container 9 by a force when the mounting cap 17 is caulked. As the housing holding portion 19b bends inward, the housing 18 is firmly held inside the housing holding portion 19b. In particular, if the housing 18 is made of metal such as stainless steel, the housing 18 is more firmly held by the elastic force. Therefore, even if the propellant is filled from the stem, the housing does not fall due to the filling pressure. Further, since the mounting cap 17 is attached to the container body 9 via the housing holding body 19, it does not directly touch the second content B. Therefore, the material of the mounting cap 17 is not affected by the second content B.

FIG. 7 b shows still another embodiment of the valve mechanism of the second container 2. The fitting piece 18b of the housing 18 of the valve mechanism 15b is a large-diameter portion provided above the storage portion 18a. The large-diameter fitting piece 18b is continuous with the outer peripheral surface of the storage portion 18a through a step portion 18c inclined obliquely upward and outward. Further, the protruding piece 19d of the housing holding portion 19b of the valve mechanism 15b is provided with a tapered surface 19e extending outwardly so as to be in contact with the inclined surface of the stepped portion 18c. For this reason, the housing holding portion 19b of the housing holding body 19 is compressed inward through the vicinity of the mouth portion 9e of the container main body 9 of the second container by the force when the mounting cap 17 is caulked. The inward compression force of the housing holding portion 19b is transmitted from the tapered surface 19e of the protruding piece 19d to the inclined surface of the step portion 18c of the housing 18. Since the housing 18 is pulled upward by the force received from the inclined surface of the step portion 18 c, the housing 18 can be firmly held by the housing holder 19 by caulking the mounting cap 17. Further, the vicinity of the step portion 18c of the housing 18 that supports the compressive force is thickened to increase its strength. Furthermore, an introduction bottom hole 18e is formed at the bottom of the storage portion 18a of the housing 18 of the present embodiment, and the content B is guided into the stem 11 through this hole.

Returning to FIG. 1, the shrink film 3 is provided in a cylindrical shape, and a transparent portion 3 a having transparency to the extent that the contents of the synthetic resin container main body can be visually confirmed from the outside is provided in part of the shrink film 3. Have. The see-through part 3a is provided on the side surface on the short side when connecting the first container 1 and the second container 2 (see reference numeral 3b in FIG. 2b), and before and during use through the see-through part 3a. The amount of contents can be confirmed visually. The shape includes a strip shape, a slit shape, a spiral shape, an elliptical shape, etc., but if it extends in the vertical direction to the extent that the remaining amount can be confirmed, it may be a curved shape in the middle, and further, a circle, A plurality of small see-through portions such as triangles and squares may be provided.
As shown in FIGS. 8A to 8D, in the case of the slit shape, the transmission of light can be reduced, and deterioration due to light can be reduced. Further, as shown in FIG. 8a, the slit may be a horizontal slit, or the slit may be a scale. In addition, when the see-through part 3a of the shrink film is from the lower end to the upper end of the side surface of the container body, the legal display, legal precautions and usage instructions provided on the container body overlap with the see-through part. It is preferable to align the positions so as not to occur.
In the embodiment shown in FIG. 8e, the vicinity of the upper end of the see-through portion 3a is made substantially the same as the position of the liquid surface 3d when the contents B filled in the container body 9 are not used. At this time, by providing the lower end of printing of the container body above the see-through portion, there is no overlap between the printing and the see-through portion, so the orientation of the container body is not necessary, and the production efficiency is increased. In the case of using a horizontal slit-shaped fluoroscopic part as shown in FIG. 8a, the liquid level 3d may be arranged near the upper end of the slit provided on the top.
Returning to FIG. 2b, the short side portions 3b and 3b of the shrink film 3 on the left and right sides (left and right direction in FIG. 2b) are in contact with the container body 6 of the first container and the container body 9 of the second container, respectively. Since the materials of the two container bodies 6 and 9 are metal and synthetic resin, respectively, the thermal conductivity is different in the short side portions 3b and 3b on the left and right (left and right direction in FIG. 2b). On the other hand, since the long side portions 3c and 3c in the vertical direction (the vertical direction in FIG. 2b) are in contact with air (the portions not in contact with the first container 1 and the second container 2), the thermal conductivity is the same. Therefore, when the shrink film 3 is heated and contracted, the contraction of the long side portions 3c and 3c is more stable than that of the short side portions 3b and 3b. That is, by providing a legal display or the like on the long side portion 3c in which the heat contraction state is stable, it is easy to finish the character after contraction to a predetermined size. And the manufacturing process to heat-shrink can be made easy.

  The shrink film 3 is a heat-shrinkable plastic and is a conventionally known film such as a stretched film. For example, polyester such as polyethylene terephthalate (PET), polyolefin such as polypropylene and polyethylene, polyvinyl chloride, and the like can be used. In order to prevent the contents from being deteriorated by light, it is possible to apply a component that absorbs ultraviolet rays or deposit a powder that scatters ultraviolet rays on at least a part including the fluoroscopic part. preferable. The shrink film 4 is mounted on a connecting member, which will be described later, on top of the first container 1 and the second container 2 filled with the contents, and is placed in parallel, and the vicinity of each trunk is heated. It is coated by shrinking.

The container body 9 shown in FIG. 5 is provided with a printed portion 2a on the side surface on which a display of legal indications, usage methods, precautions for use, etc. stipulated by the Pharmaceutical Affairs Law, the Fire Service Law, the High Pressure Gas Safety Law, etc. is printed. ing. These printed portions 2a are arranged so as not to overlap with the see-through portion 3a (see FIG. 1) of the shrink film. For example, when the printed portion 2a is printed by an inkjet or the like, or when a printed seal (not shown) is attached, the adhesive component 2b is applied to the top or bottom of the printed portion 2a, and the first container 1 By contacting the container main body 4, it is possible to reliably prevent the printed portion 2a of the second container from adhering to the first container side and the see-through portion 3a and the printed portion 2a from overlapping each other. Alternatively, a mark may be attached to the top or bottom of the print portion 2a, or the mark may be read to direct the print portion toward the first container 1 side.
In addition, as the said adhesive component 2b, what can adhere | attach a synthetic resin, a metal, and synthetic resins satisfactorily, such as a hot melt and an adhesive tape, is preferable.

  Returning to FIG. 2, the discharge member 4 is mounted on the stems 8 a and 11 of the valves of the first container 1 and the second container 2, respectively, and a pressing portion 21 that discharges two liquids, the first container 1, The first container 1 is attached to the mounting caps 8b, 17 (see FIG. 3) of the two containers 2 and is connected to the connecting members 20 for integrally connecting the container bodies 6, 9 together. The outer cover 21d made of synthetic resin is placed on the shoulders 6c, 9b (see FIG. 3) of the second container 2.

  As shown in FIG. 3, the pressing portion 21 includes vertical members 21 a and 21 a fitted to the stems 8 a and 11, a horizontal member 21 b connecting the upper ends of the vertical members, and a central portion of the horizontal member. And a nozzle 21c projecting forward from the nozzle 21c. The push portion 21 is guided by the inner side surface of the outer cover 21d so as to be movable up and down. Note that a lever (not shown) for pressing the pressing portion 21 downward may be swingably attached to the outer cover 21d.

Returning to FIG. 2, the connecting member 20 includes a first mounting portion 20 a for mounting the first container 1 and a second mounting portion 20 b for mounting the second container 2. The first mounting portion 20a and the second mounting portion 20b are shaped so as to be fitted to the mounting caps 8b and 17 (see FIG. 3) of the first container 1 and the second container 2, respectively. And when connecting both containers with the connection member 20, the 1st mounting part 20a and the 2nd mounting part 20b are each in a height direction so that the height position of the front-end | tip of each stem 8a, 11 may align. The positions to be fitted to the mounting caps 8b and 17 are adjusted in advance.
Furthermore, since the 1st container 1 and the 2nd container 2 are connected by the connection member 20, and those relative movement is controlled, for example, using the container main body of a different material like aluminum and polyethylene terephthalate, The direction in which the shrink film 3 shrinks can be adjusted, and the shape after shrinkage can be stabilized.

  9a and 9b show another embodiment of the connecting member. The connecting member 22 shown in FIGS. 9a and 9b is divided into a first mounting member 22a having a first mounting portion and a second mounting member 22b having a second mounting portion, and the members 22a and 22b can be freely engaged and disengaged. Has been. Therefore, since the members 22a and 22b can be engaged with each other after the first container 1 and the second container 2 are mounted on the separate mounting members 22a and 22b, the material and shape of the one connecting member 22 are different. Compared with connecting the two containers 1 and 2, the working efficiency is high. Moreover, since there is an engaging part, the position of the containers 1 and 2 with respect to the connecting member 22 can be determined. That is, the printed portions on the outer surfaces of the containers 1 and 2 can be positioned so as to face each other.

FIG. 10 shows still another embodiment of the connecting member. The connecting member 23 shown in FIG. 10 includes a second mounting portion 20b having the same shape as the shape of mounting the first container 1 of the first mounting portion 20a. The second mounting portion 20b is mounted with a mounting auxiliary member 20c having an outer surface shape substantially the same as the side peripheral surface of the mounting cap 17 of the first container 1. Details of the mounting assisting member 20c are shown in FIGS. The mounting auxiliary member 20c shown in FIG. 11a has an upper outer shape that can be mounted on the first mounting portion 20a and the second mounting portion 20b (in FIG. 10, the mounting shape of the first container 1 is the same). ). An annular groove 20d is formed on the outer peripheral surface of the mounting auxiliary member 20a, and the annular groove 20d is formed on an annular protrusion (not shown) formed on the inner surface of the second mounting portion 20b (first mounting portion 20a). It is fixed by engaging. The annular protrusion of the first mounting portion 20a is engaged with a portion (see reference numeral 8c in FIG. 4) caulked inward of the mounting cap 8b (see FIG. 4) of the first container 1. As shown in FIG. 11b, the inner surface of the mounting auxiliary member 20c has a shape for mounting the second container 2, and a plurality of protrusions 20d are annularly formed on the inner surface. A mounting auxiliary member 20c is mounted on the second mounting portion 20b, and the second container 2 is mounted via the mounting auxiliary member 20c. For this reason, when attaching the 1st container 1 and the 2nd container 2 to the connection member 23, direction regulation becomes unnecessary and production efficiency becomes high.

Returning to FIG. 3, the holding cap 5 is molded into a bottomed cylindrical shape or a cylindrical shape using a synthetic resin such as polypropylene. The holding cap has an opening attached to the hemispherical bottom of the second container 2. Since the holding cap 5 has a thin cylindrical opening, the holding cap 5 is slightly expanded by the pressing force when it is attached to the hemispherical bottom, and can be adjusted in height before the two containers are connected by the shrink film. . Further, by shrinking the shrink film in this state, it can be fixed in a state where the height of the container is matched.
In addition, the first container 1 and the second container 2 can be connected by the holding cap 5 so that the lower ends of the two containers are fixed, and the relative movement between the first container 1 and the second container 2 is restricted. Has been. In particular, when the upper ends of the two container bodies 4 and 9 are connected by the connecting member 20, the effect of restricting the movement in the axial direction of each other is increased, so that the two containers 1 and 1 are further formed by the shrink film 3 (see FIG. 1). It is easy to connect the two. Furthermore, even if the container is placed in a place that is easily wetted, such as a wash basin, the bottom is prevented from coming into contact with water and is not easily corroded. If the holding cap 5 is formed of a transparent material or a material that easily transmits light, the see-through portion of the trunk portion 9d by external light entering from the bottom portion 9a of the container body 9 of the first container (see reference numeral 3a in FIG. 1). The inside is easy to see.

  Returning to FIG. 1, the discharge device 24 stores the first content A (A agent) and the second content B (B agent) separately, and mixes them during use. In this embodiment, it is suitably used for a product that reacts and exhibits an effect by mixing two liquids, such as a two-liquid hair dye or a two-liquid exothermic preparation.

As a two-component hair dye, for example, a first content A composed of an aqueous stock solution and a propellant containing an oxidation dye, an alkali agent, a surfactant, and the like, and an oxidation agent for oxidizing the oxidation dye 2nd content B which consists of the aqueous | water-based stock solution and propellant which were made.
The oxidation dye includes, for example, a dye intermediate (dye precursor) composed of a para component such as p-phenylenediamine and p-aminophenol, an ortho component such as o-phenylenediamine and o-aminophenol, or a derivative thereof. And couplers having various color tones in combination with the above-mentioned dye intermediates such as meta-phenylenediamine, aminophenol and polyhydric phenols.

The alkaline agent is blended for the purpose of improving the hair dyeing effect and for the purpose of obtaining a bright color tone by simultaneously proceeding the oxidative degradation of melanin granules in the hair. It also has the function of maintaining alkalinity so that the oxidation dye does not develop color during storage. Examples of the alkaline agent include ammonia water, ammonium hydrogen carbonate, monoethanolamine and the like.
The aqueous stock solution used for the first content A can be adjusted by blending an oxidation dye, an alkaline agent or the like with water. In addition, an oil phase base, a surfactant, a solubilizer, an antioxidant and the like can be blended. The aqueous stock solution has a pH of about 8 to 13, particularly preferably in the range of 9 to 11.

On the other hand, the aqueous stock solution used for the second content B filled in the second container 2 can be adjusted by blending an oxidizing agent such as hydrogen peroxide with water together with a stabilizer. The aqueous stock solution has a pH of about 2 to 5, particularly preferably in the range of 2 to 4.

  Examples of the propellant include liquefied petroleum gas (main components: propane, i-butane and n-butane), dimethyl ether, hydrofluoroolefin, and liquefied gas obtained by mixing them, such as carbon dioxide, nitrogen, and air. Compressed gas is also used.
