There is.

Patent No. 5279970

By the way, gas may be mixed in the pouch, and the gas is in a state of being compressed by the pressurizing agent filled in the outer container. Therefore, if a gas is mixed in the stock solution, it expands when it is discharged to the outside and the volume becomes large, so that the discharge rate of the stock solution becomes high. As a result, there is a problem that the undiluted solution is vigorously discharged and it becomes difficult to apply it to an object such as a brush. Especially when the pressure inside the container is high, such as when starting to use, the degree of compression of the gas inside the pouch is large, and when it is discharged from the stem hole to the outside, it expands significantly due to the pressure difference from the atmospheric pressure. The discharge state of the undiluted solution is not stable, such as the discharge speed of the stock rapidly increasing. Therefore, when filling the pouch with the undiluted solution, measures such as sucking the inside of the pouch may be taken in advance, but it is difficult to completely remove the air because air tends to remain in the parts that are difficult to deform such as valves. is there.

Therefore, before shipping the discharged product, the valve is operated (opened) for a certain period of time to remove the air accumulated above the pouch, but the cause of the gas accumulation in the pouch is the pressurizing agent. However, there are some that occur after a certain period of time, such as permeation through the pouch or generation of gas from the undiluted solution itself, so it cannot be said that this is a sufficient countermeasure.

Therefore, an object of the present invention is to provide a discharge container capable of suppressing a discharge failure of a stock solution caused by a gas in a pouch.

The discharge container of the present invention includes an outer container 10, a pouch 20 housed in the outer container 10 for storing the undiluted solution C, a valve assembly 40 attached to the opening 10f of the outer container 10, and a pouch 20. A discharge container including a flow path member 30 that communicates with the valve assembly 40. The flow path member 30 is interposed at a bonding portion of the pouch 20 and communicates with a communication portion 32 that communicates inside and outside the pouch 20. An extension 33 that extends the undiluted solution passage S in the 32 downward, and a flow path forming portion 34 that extends from the extension 33 toward the bottom 10a of the pouch 20 and forms a flow path of the undiluted solution C toward the extension 33 side. The undiluted solution passage S opens below the upper end of the undiluted solution accommodating chamber 20d in the undiluted solution accommodating chamber 20d in the pouch 20, and a gas storage portion R for retaining the gas G is formed above the opening. It is characterized by being.

Further, it is preferable that a regulating means for regulating the adhesion between the inner surfaces of the pouches in the gas storage portion R is interposed in the bonding portion of the pouch 20.

It is preferable that the regulating means is composed of the communication portion 32 which is wider than the extension portion 33.

It is preferable that the regulating means is composed of recesses 32b formed on the lower surface of the communication portion 32.

Further, a part of the stock solution storage chamber 20d may be expanded upward.

In the discharge container of the present invention, since the undiluted solution passage opens below the upper end of the undiluted solution accommodating chamber in the undiluted solution accommodating chamber and a gas storage portion for retaining gas is formed above the opening, the inside of the pouch is formed. Even if a gas is present, it is possible to suppress the discharge of the gas and prevent the undiluted solution from being discharged vigorously, such as by gradually discharging the gas or preventing the discharge of the gas.

Further, if the pouch bonding portion is provided with a regulatory means for regulating the adhesion between the inner surfaces of the pouches in the gas storage portion, the gas is stored even if the undiluted solution in the pouch is reduced by the discharge and the inner surfaces of the pouches come close to each other. The capacity of the part can be secured, and the discharge of gas can be further suppressed.

In particular, if the regulating means is configured to make the communication portion wider than the extension portion, the inner surfaces of the pouches around the lower surface of the communication portion and around the inside corner formed by the communication portion and the extension portion. It is possible to regulate the close contact of the gas, and it is easy to secure a gas storage part.
Further, when the regulating means is composed of recesses formed on the lower surface of the communication portion, a predetermined amount of capacity of the gas storage portion can be secured until the undiluted solution in the pouch is exhausted.

Further, if a part of the stock solution storage chamber is expanded upward, the expanded part also functions as a gas storage part, and the discharge of gas can be further suppressed.

Next, the discharge container (aerosol container) of the present invention will be described with reference to the drawings. First, the outline of the discharge container 1 of the present invention will be described. As shown in FIG. 1, the outer container 10, the pouch 20 housed in the outer container 10 and containing the undiluted solution C, and the outer container 10 thereof. A valve assembly 40 attached to the opening 10f and a flow path member 30 that communicates the pouch 20 and the valve assembly 40 are provided. Then, the pouch 20 is filled with the undiluted solution C, and the space between the outer container 10 and the pouch 20 is filled with the pressurizing agent P, so that the undiluted solution C is discharged by the pressure of the pressurizing agent P. The product (aerosol product) is manufactured.
Hereinafter, each component will be specifically described.

First, the outer container 10 will be described. As shown in FIG. 1, the outer container 10 has a cylindrical body portion 10b whose lower end is closed by a bottom portion 10a, and the diameter of the outer container 10 is reduced upward from the upper end of the body portion 10b. The dome-shaped shoulder portion 10c provided as described above, the cylindrical neck portion 10d provided at the upper end of the shoulder portion 10c, the flange portion 10e formed in an annular shape at the upper end of the neck portion 10d, and the inside of the flange portion 10e. It is provided with an opening 10f that opens on the peripheral side. Further, in order to ensure pressure resistance, five legs 10g are provided so as to be arranged at equal intervals in the circumferential direction downward (so-called petaloid), and the diameter is reduced from the lower part of the body part 10b to the bottom part 10a. ing.

The outer container 10 is manufactured by, for example, biaxially stretched blow molding a synthetic resin such as polyethylene terephthalate (PET), nylon or polypropylene, and has transparency or translucency. The outer container may be colored or opaque. However, the outer container 10 may be formed by, for example, pressing or squeezing a metal such as aluminum. In this case, the light-shielding property, heat resistance, and gas barrier property are high.

As shown in FIG. 1b, two pouches 20 are housed in the outer container 10. These pouches 20 are formed by stacking a plurality of sheets or folding one sheet and then laminating the peripheral edges with heat welding, an adhesive or the like (bag making process).

As shown in FIG. 2, the shape of the pouch 20 is substantially rectangular, and the bonding portions 20a, 20b, and 20c are formed on the upper portion, both side portions, and the lower portion, respectively. Then, a stock solution storage chamber 20d for filling the stock solution C is formed in a rectangular portion surrounded by these bonding portions 20a, 20b, and 20c. The width of the pouch 20 is larger than the opening diameter of the opening 10f of the outer container 10 and larger than the inner diameter of the body portion 10b. The lower bonding portion 20c has a semicircular notch 20e that triggers the pouch 20 to be folded in the width direction, and a notch 20f that is cut off at both ends to facilitate insertion into the outer container 10. Is provided. However, these notches 20e and 20f do not necessarily have to be provided. In FIG. 1a, 20 g is a bent line generated when the corner portion of the pouch 20 abuts on the inner surface of the shoulder portion 10c of the outer container 10.

The sheet constituting the pouch 20 is determined by the undiluted solution C contained therein. For example, a synthetic resin sheet such as polyethylene, polypropylene, polyethylene terephthalate, nylon, or ever, or a vapor-deposited resin obtained by depositing silica or alumina on the synthetic resin sheet. Examples thereof include a sheet, a metal foil sheet such as aluminum, a synthetic resin sheet, a vapor-deposited resin sheet, and a laminated sheet in which at least two sheets selected from the metal foil sheet are laminated (particularly, a laminated sheet having a metal layer). In the present embodiment, since the two-component reaction type preparation is filled as the undiluted solution C, a configuration suitable for each undiluted solution C can be selected. For example, when a two-component hair dye is used as a two-component reaction type preparation, the pouch 20 filled with the first agent containing an oxidation dye that exerts a hair dyeing effect by being oxidized is oxygen-blocking. The pouch 20 is composed of an opaque laminated sheet in which both sides of a high metal foil sheet are laminated with a synthetic resin sheet having high chemical resistance, and is filled with a second agent containing an oxidizing agent such as hydrogen peroxide. It is composed of a high-quality synthetic resin sheet. In addition, in the case of a synthetic resin sheet, it can be configured to have transparency or translucency. In this case, if the outer container is also transparent, it is possible to check the remaining amount of the undiluted solution and the presence or absence of air bubbles. Further, a laminated sheet obtained by laminating a synthetic resin sheet having a high gas barrier property such as nylon or Eval and a synthetic resin sheet having a high chemical resistance such as polyethylene or polyethylene terephthalate may be used.

The flow path member 30 is an integrally molded product of a synthetic resin such as polyethylene, polypropylene, or polyacetal, and as shown in FIGS. 3a and 3b, the mounting portion 31, the communicating portion 32, the extension portion 33, and the flow path forming portion are formed from above. It is equipped with 34. Further, the flow path member 30 is provided with an internal passage (a stock solution passage S through which the stock solution C from the stock solution storage chamber 20d is passed: shown by a dotted line in the figure) from the mounting portion 31 to the extension portion 33, but the flow path is formed. The portion 34 is not provided, and the flow path of the undiluted solution is formed by the unevenness of the surface of the flow path forming portion 34 and the inner surface of the pouch. The internal passage S and the flow path are communicated with each other by a lead-out hole 35 opened by a through hole between the upper end of the flow path forming portion 34 and the lower end of the extension portion 33.

The mounting portion 31 is a portion mainly for connecting to the housing 51 of the valve 50 of the valve assembly 40, and has a substantially cylindrical shape, and the upper end thereof engages with the engaging step portion 60c of the valve holder 60 described later. It is provided with an engaging claw 31a for the purpose.

The communication portion 32 is a portion that is interposed in the upper bonding portion 20a of the pouch 20 and secures a passage that communicates the stock solution storage chamber 20d and the outside of the pouch 20 (inside the housing 51 of the valve 50). Further, it is also a portion for fixing (welding) the pouch 20 by heat welding, ultrasonic welding, or the like, and can be said to be a welded portion. As shown in FIG. 3c, the shape of the communication portion 32 is a substantially rhombus in a plan view, and is flat along the surface of the sheet constituting the pouch 20. Further, in order to strengthen the fixing of the pouch 20, a plurality of horizontal ribs 32a extending in the horizontal direction are formed on the side surface thereof.

The extension portion 33 is a portion for extending the internal passage S of the communication portion 32 below the upper end of the stock solution storage chamber 20d, and extends downward from the lower end of the communication portion 32 (bottom of the pouch 20). It is installed (see FIGS. 1a and 1b). The length of extending the internal passage S (the length from the upper end of the stock solution storage chamber 20d to the upper end of the lead-out hole 35) is, for example, 3 to 45 mm, preferably 5 to 30 mm, and the lead-out hole 35 is provided in the stock solution storage chamber 20d. It is provided above 1/2 of the height, preferably above 1/3 of the height. The planar shape of the extension portion 33 is substantially a rhombus. However, since the communication portion 32 is wider, an inside corner portion is formed between the communication portion 32 and the communication portion 32.

The flow path forming portion 34 is a rod-shaped body extending downward (bottom of the pouch 20) from the lower end of the extension portion 33, and a plurality of irregularities are provided on the surface, and the pouch 20 is formed by the irregularities. The sticking (adhesion) between the constituent sheets is suppressed, and the flow path of the undiluted solution C is secured.

The plurality of irregularities are formed on a plurality of main ridges 34b provided at regular intervals in the vertical direction along the central axis of the rod-shaped main body portion 34a, and on both sides of the main ridges 34b, the main ridges 34b. It is composed of a plurality of sub-ridges 34c provided at regular intervals in the vertical direction and at regular intervals in the vertical direction. The main ridge 34b and the sub ridge 34c are provided so as to be displaced from each other in the vertical direction so that the sub ridge 34c is located between the main ridges 34b. Further, a valley portion 34d connected in the vertical direction is formed between the main ridge 34b and the sub ridge 34c, and this valley portion 34d forms a flow path of the stock solution C. The upper end of the flow path is connected to a lead-out hole 35 provided so as to straddle the front and back surfaces of the main body portion 34a.

As shown in FIG. 4, the valve assembly 40 covers the valves 50 for two independent pouches, the valve holder 60 for receiving the valves 50, the valve 50 and the valve holder 60, and puts the valve holder 60 in the outer container 10. It is composed of a mountain cover 70 to be fixed.

The valve 50 is for filling the pouch 20 with the undiluted solution C, and selectively discharges / shuts off the undiluted solution C filled in the pouch 20 to the outside, and is a flow path member. A tubular housing 51 to which the mounting portion 31 of the 30 is mounted (outer fitting), a stem 52 that is movably inserted into the housing 51, and a stem that closes the stem hole 52a provided on the side surface of the stem 52. It is composed of a rubber 53, a spring 54 that constantly urges the stem 52 upward, and a cover 55 that fixes the stem 52 and the stem rubber 53 to the housing 51.

The valve holder 60 is for closing the opening 10f of the outer container 10 and holding the two valves 50, and communicates with the plug portion 60a having substantially the same diameter as the opening 10f in the vertical direction. It is provided with a holder portion 60b. Further, the holder portion 60b is formed with an engaging step portion 60c for engaging with the engaging claw 31a of the flow path member 30, and while engaging with the flow path member 30, the flow path member 30 and the valve. The connection state with 50 is strengthened.

The mountain cover 70 covers the cover portion 70a that covers the valve 50 and the valve holder 60 and the flange portion 10e of the outer container 10, and crimps the valve holder 60 toward the lower surface side of the flange portion 10e to make the valve holder 60 into the outer container 10. It is composed of a fixing portion 70b for fixing.

A discharge product using the discharge container 1 having the above configuration is manufactured as follows. First, the pouch 20 is fixed to the flow path member 30 to integrate the two. Specifically, in the flow path member 30, the parts (communication part 32, extension part 33, flow path forming part 34) other than the mounting part 31 are interposed between the sheets constituting the pouch 20. Stick the edges together. At this time, after the communication portion 32 is positioned at the planned bonding portion, the inner surface of the sheet and the outer surface of the communication portion 32 are fixed to each other. Further, the upper end of the stock solution storage chamber 20d (the lower end of the upper bonding portion 20a) is fixed so as to be located at the boundary between the communication portion 32 and the extension portion 33. By doing so, the lower surface of the communication portion 32 is exposed (facing) to the stock solution storage chamber 20d side. Further, the extension portion 33 and the flow path forming portion 34 are located in the stock solution storage chamber 20d.

After integrating the pouch 20 and the flow path member 30, the mounting portion 31 of the flow path member 30 is subsequently engaged with the engaging step portion 60c of the valve holder 60. Then, the valve 50 is inserted into the holder portion 60b of the valve holder 60. As a result, the housing 51 and the mounting portion 31 are connected, and the stock solution accommodating chamber 20d and the valve 50 communicate with each other.

Next, the pouch 20 is inserted into the outer container 10. Then, the pressurizing agent P is filled between the outer container 10 and the pouch 20. The pressurizing agent P is filled in a state where the valve holder 60 is slightly lifted from the opening 10f of the outer container 10 (that is, undercup filling). The pressurizing agent P is filled with a compressed gas such as nitrogen, compressed air, carbon dioxide gas, or nitrous oxide. The pressure after filling is, for example, 0.4 to 1.0 MPa at 25 ° C. After filling with the pressurizing agent, the valve holder 60 is pushed down to come into contact with the opening 10f of the outer container 10, and the lower end of the mountain cover 70 is crimped to be fixed to the outer container 10.

Then, after sucking and discharging the air in the pouch 20 from the stem 52, the pouch 20 is filled with the undiluted solution C through the valve 50. Examples of the undiluted solution C include a two-component hair dye, a two-component perm agent, a two-component adhesive, and a cream, gel, and liquid of a two-component reaction type preparation. After that, a discharge member (not shown) is attached to the valve assembly 40 to manufacture a discharge product.

In the discharge product having the above configuration, the flow path member 30 includes an extension portion 33 that extends the stock solution passage S of the communication portion 32 downward, and the stock solution passage S opens below the upper end of the stock solution storage chamber 20d. Therefore, a gas storage portion R capable of retaining gas by the length of the extension portion 33 is formed in the upper part of the stock solution storage chamber 20d. Further, since the communication portion 32 is wider than the extension portion 33, the contact between the inner surfaces of the pouches is restricted by the lower surface of the communication portion 32 and the inside corner formed by the communication portion 32 and the extension portion 33. (Functions as a regulatory means: see the alternate long and short dash line in FIG. 4), and the capacity of the gas reservoir R is unlikely to decrease. Therefore, although the flow path member 30 for discharging the stock solution C from the upper part of the pouch 20 (near the lead-out hole 35) is used, the discharge of the gas G in the stock solution can be suppressed, and the discharge of the stock solution C can be suppressed. It is possible to suppress a problem that the speed suddenly increases and the gas is discharged vigorously. When the discharged product is stored for a long period of time, the pressurizing agent P may permeate through the pouch 20 and be mixed in the undiluted solution, or the gas generated by the decomposition of the undiluted solution C may be mixed in the undiluted solution. Since the density is lower than that of the undiluted solution C, it easily moves to the upper part of the undiluted solution storage chamber 20d and is easily stored in the gas storage unit R. As the undiluted solution C is discharged, the inner surfaces of the pouches facing each other come close to each other, and the capacity of the gas storage portion R decreases accordingly, but the capacity decreases gradually and does not occur all at once. Even if the gas G is discharged, it is discharged little by little, and the discharge state of the undiluted solution C does not vary greatly. Further, since the compressed gas is used as the pressurizing agent P, when the stock solution C in the pouch 20 decreases, the pressure in the outer container 10 decreases accordingly, so that the gas G expands significantly even if it is discharged. However, the discharge rate of the undiluted solution is unlikely to increase as the undiluted solution C scatters from the discharge nozzle.

The inside corner also acts as an air pool when the stock solution is filled, and the air collected in the inside corner remains in the pouch 20 together with the air in the housing 51 and the stock solution passage S that could not be completely sucked. However, since the pressure inside the outer container 10 becomes high after the undiluted solution is filled, it is compressed and its volume becomes small, and it is easy to be stored in the gas storage unit R.

FIG. 5 shows another flow path member 30A. As shown in the figure, the flow path member 30A is provided with a recess 32b that opens downward on the lower surface of the communication portion 32. In this state, a tubular body having an upper bottom (welded portion to be welded to the pouch) is separately provided on the outer periphery of the communicating portion, and a space is formed between the outer surface of the communicating portion and the inner surface of the tubular body. I can say. In the case of such a configuration, not only the adhesion between the inner surfaces of the pouches located near the lower part of the communication portion 32 is regulated (functions as a regulating means), but also the gas storage portion R is located above the stock solution storage chamber 20d. As a result, it is possible to form a space that is not affected by the discharge of the undiluted solution C (the capacity does not change), so that the discharge of the gas G can be further suppressed. In this form, the upper end of the stock solution storage chamber 20d is the lower surface of the upper bottom of the recess 32b. Therefore, if the height position of the lead-out hole 35 is lower than the lower surface of the upper bottom of the recess 32b, for example, it is located above the lower end of the recess 32b (the lower end of the communication portion 32), and the upper part of the pouch 20 is attached. It may be above the lower end of the mating portion 20a.

FIG. 6 shows a pouch with a characteristic shape. In the pouch 20A shown in FIG. 6a, the length of the upper bonding portion 20a in the vertical direction is different in the width direction. Specifically, the length of the bonding portion in the center in the width direction is set below both ends in the width direction. By lengthening it, a part (upper end corner) of the stock solution storage chamber 20d is expanded upward. By expanding the stock solution storage chamber 20d in this way, the expanded portion can be used as the gas storage unit R, and the capacity of the gas storage unit R can be increased. In particular, the upper end corner (shoulder) of the pouch 20A abuts on the inner surface (inner surface of the shoulder 10c) of the outer container 10 and bends when housed in the outer container 10 (see the one-dot chain line in the figure), but the bending line 20g Therefore, the shoulder portion of the pouch 20A can be made into a space in which the undiluted solution is difficult to invade, but the gas G having an extremely low viscosity as compared with the undiluted solution can easily invade, and can be effectively used as the gas storage portion R.

In the pouch 20B shown in FIG. 6b, the gas storage portion R is expanded to the upper end corner by using a sheet having an upper end corner extended upward as the sheet constituting the pouch. With such a configuration, the position of the pouch in the outer container 10 is located higher than that of the other pouches 20 and 20A using a substantially rectangular sheet, and the pouch is located on the inner surface of the outer container 10. There is an advantage that the corners of the can be easily brought into contact with each other.

Although the typical embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example, the number of pouches is not limited to two, and may be one or three or more. Further, the type of pouch may be one composed of two sheets or one having a gusset portion. Further, in the discharge container of FIG. 1, for both of the two pouches, the flow path members (flow path members provided with the regulating means) 30 and 30A in which the communication portion is wider than the extension portion are used. It may be used for either one. For example, it may be used for a side filled with a stock solution containing a raw material that is relatively unstable such as hydrogen peroxide and generates bubbles by itself, or for a pouch formed of a sheet having gas permeability. Further, in FIG. 6, the flow path member 30B not provided with the regulating means is used, but the flow path members 30 and 30A provided with the regulating means may be used.
