Patent No. 5487011 gazette

Discharging containers containing such propellants may cause damage if compressed by a garbage collection vehicle or a waste disposal facility, so that the propellants must be completely discharged from the containers and then discarded. It is required. However, since the container used is one that has pressure resistance and does not deform, it can not be confirmed whether the propellant remains, unless the valve of the container is opened.
In view of the above problems, the present invention has an object to provide a discharge container capable of confirming whether the propellant is filled by appearance.

  The discharge container of the present invention has an outer bottle, a flexible inner bottle housed in the outer bottle, and a valve assembly attached to the outer bottle and closing the outer bottle and the inner bottle, the outer bottle and the inner bottle A discharge container for storing the undiluted solution in one of the first storage chambers or the second storage chamber in the inner bottle and storing the propellant in the other storage chamber, wherein the outer bottle is the discharge container It has a cylindrical barrel, and the barrel is provided with a fold extending in the vertical direction, and when the outer bottle has a predetermined internal pressure, it is elastically deformed so that the angle of the fold of the barrel is expanded. It is characterized.

  The discharge container of the present invention is preferably provided with a plurality of the folds. In that case, the space between the folds is a flat surface, and when the outer bottle has a predetermined internal pressure, the flat surface elastically deforms to a curved surface projecting outward, or It is preferable that the space is a curved portion that protrudes inward, and that when the outer bottle has a predetermined internal pressure, the curved portion elastically deforms to a curved surface that protrudes outward. And it is preferable that the barrel of the outer bottle is a substantially polygonal cylinder, in particular, a substantially regular polygonal cylinder.

The discharge product of the present invention is characterized by comprising the discharge container of the present invention, the stock solution stored in the first storage chamber, and the propellant stored in the second storage chamber.
A second aspect of the discharge product of the present invention is characterized by comprising the discharge container of the present invention, the stock solution stored in the second storage chamber, and the propellant stored in the first storage chamber.
In the discharged product of the present invention, preferably, the propellant comprises compressed gas.

  The discharge container of the present invention has an outer bottle, a flexible inner bottle housed in the outer bottle, and a valve assembly attached to the outer bottle and closing the outer bottle and the inner bottle, the outer bottle and the inner bottle A discharge container for storing the undiluted solution in one of the first storage chambers or the second storage chamber in the inner bottle and storing the propellant in the other storage chamber, wherein the outer bottle is the discharge container It has a cylindrical barrel, and the barrel has a fold extending in the vertical direction, and when the outer bottle has a predetermined internal pressure, it is elastically deformed so that the angle of the fold of the barrel is expanded, The elastic deformation makes the contour of the outer bottle fold thinner. Therefore, it can be known from the appearance of the outer bottle whether or not the propellant is stored. Also, the folds extending up and down increase the strength of the outer bottle in the up and down direction. Therefore, manufacture of a discharge container can be simplified, such as attachment to the outer bottle of a valve assembly from the upper part, for example.

In the discharge container of the present invention, in the case where a plurality of the folds are provided, the contour of each fold changes, so that the change in the appearance of the outer bottle can be seen more clearly. The strength in the vertical direction of the outer bottle also becomes stronger.
When the outer bottle has a predetermined internal pressure, when a space between the plurality of folds is a flat portion and the outer bottle has a predetermined internal pressure, the flat portion elastically deforms to a curved surface projecting outward. The barrel of the outer bottle has a rounded shape, and the difference from the state without the internal pressure is further clarified.
When the outer bottle has a predetermined internal pressure, the outer bottle can be deformed to a curved surface in which the curved portion protrudes outward when the outer bottle has a predetermined internal pressure. When having a predetermined internal pressure, the body has a rounded shape, and the difference from the state without the internal pressure is clear.
When the body portion of the outer bottle is a substantially polygonal cylinder, when the outer bottle has a predetermined internal pressure, it has a substantially cylindrical shape, and it is easy to understand the difference from the state without the internal pressure. In particular, in the case of a substantially regular polygonal tube, the appearance may be good.

  Since the discharge product of the present invention comprises the discharge container of the present invention, the stock solution stored in the first storage chamber, and the propellant stored in the second storage chamber, the stock solution and the propellant are stored. The presence of the container can be recognized not only by visual observation but also by the feel when the container is gripped by the change of the barrel of the outer bottle (the angle of the folded portion, the curved surface projecting outward, etc.). Further, according to the first aspect, not only the inner bottle but also the outer bottle and the stock solution are interposed between the propellant and the outside air, and permeation of the propellant to the outside can be prevented as much as possible. And since it is not necessary to think about permeation of a propellant as a role of an outer bottle, it is possible to make an outer bottle thin and to make the trunk part into a thickness that can be elastically deformed by an internal pressure.

  The second aspect of the discharge product of the present invention also includes the discharge container of the present invention, the stock solution stored in the second storage chamber, and the propellant stored in the first storage chamber. It can be recognized not only by visual observation but also by the feeling when holding the container that the agent is stored by the change of the barrel of the outer bottle (the angle of the folding portion, the curved surface projecting outward, etc.) . In the second aspect, since the inner bottle contracts with the discharge of the stock solution, the discharge passage of the stock solution is not blocked, and the remaining amount of the stock solution is small.

In the discharge product of the present invention, when the propellant is made of compressed gas, discharging the stock solution increases the volume of the storage chamber for storing the compressed gas, and at the same time, the internal pressure of the outer bottle decreases. That is, by discharging the stock solution, the elastic deformation of the folded portion (and the flat portion or the curved portion) of the outer bottle is gradually released. Therefore, the remaining amount of the stock solution can be recognized by the appearance of the outer bottle and the feel when the container is gripped.
In particular, when the propellant of the first aspect of the discharged product of the present invention is a compressed gas, when the undiluted solution in the first storage chamber is discharged and the internal pressure decreases, the angle of the outer bottle folding portion narrows. A gap can be easily formed between the incoming inner bottle and the first storage chamber which contracts the discharge passage of the stock solution communicating between the first storage chamber and the outside air. Further, when the stock solution is stored in the first storage chamber of the discharge container of the present invention and the propellant is stored in the second storage chamber, the inner bottle is expanded with the discharge of the stock solution and the stock solution is pressed against the entire inner surface of the outer bottle, When the amount of undiluted solution decreases, the drop in liquid level is not seen like a general discharge container, but it is difficult to check the remaining amount in appearance but due to changes in the angle of the fold and the curved surface that protrudes outward, It can be recognized by visual observation and touch when holding the container.

  The discharge product 10 of FIG. 1 includes an outer bottle 11, a flexible inner bottle 12 accommodated in the outer bottle 11, and a valve assembly 13 attached to the outer bottle 11 and closing the outer bottle 11 and the inner bottle 12; The undiluted solution C stored in the cylindrical first storage chamber S1 between the outer bottle 11 and the inner bottle 12 and the propellant P stored in the inner bottle 12 (second storage chamber S2) . The discharge product 10 operates the push button 14 attached to the stem 26 of the valve assembly 13 to make the first storage chamber S1 communicate with the outside, so that the pressure of the propellant P causes the inner bottle 12 to move It is expanded toward the inner surface, and the first storage chamber S1 is contracted to discharge the stock solution C.

  As shown in FIG. 2a, the outer bottle 11 has a bottom 11a, a cylindrical body 11b, a tapered shoulder 11c whose diameter decreases upward from the upper end of the body, and the upper end of the shoulder. And a cylindrical neck 11d extending upward from the container.

  The bottom portion 11a has a hemispherical shape continuous from the lower end of the body portion 11b. In particular, the inner surface of the bottom portion 11a is a curved surface continuous from the lower end of the body portion 11b. As described above, when the inner bottle 12 is expanded and deformed by continuously connecting the bottom portion 11a with the lower end of the body portion 11b, the bottom portion 11a of the outer bottle 11 and the bottom portion 12a of the inner bottle 12 closely contact. Can. That is, the first storage chamber S1 can be efficiently contracted, and the remaining amount of the stock solution C can be reduced. However, the shape of the bottom 11a is not particularly limited.

Eight folds 15 extending up and down from the trunk 11b to the shoulder 11c are formed at equal intervals in a ring shape. And between the folding part 15 and the folding part 15, it is the flat part 16 (refer FIG. 2 b). That is, when the pressure is not provided, the body portion 11b is a substantially regular octagonal cylinder, and the shoulder portion 11c is a substantially regular octagonal frustum. The inner surface of the folded portion 15 of the outer bottle 11 is a groove 15a. The fold 15 may be slightly inclined or may be spiral.
Further, the trunk portion 11b is configured to elastically deform so that the angle of the folded portion 15 is expanded at a predetermined internal pressure, and so as to curve the flat portion 16 outward. . Therefore, as shown by the broken line in FIG. 2b, when the outer bottle 11 has a predetermined internal pressure, the angle of the folding portion 15 becomes large, and the flat portion 16 is curved to expand and form an outward curved surface 16a, and the trunk portion 11b Approaches a generally cylindrical shape as a whole. In addition, the outer bottle 11 of FIG. 1 b has shown the expansion | swelling state. Therefore, in appearance, the outlines of the folding portion 15 and the flat portion 16 appear thin, and the appearance of the outer bottle 11 is in the state filled with the propellant P and in the state just before disposal after the propellant P is discharged. It is different.
In addition, as a predetermined internal pressure which elastically deforms the trunk | drum of the outer bottle 11, it is preferable that the pressure in a discharge container in 25 degreeC shall be 0.1 Mpa (gauge pressure) or more. In this case, for example, when the outer bottle 11 is molded with a synthetic resin such as polyethylene terephthalate, polypropylene, or polyamide, the thickness of the body portion 11b is 0.2 to 0.6 mm, particularly 0.25 to 0.5 mm. Is preferred.
Also in the shoulder 11c, a fold 15 continuous from the body 11b is formed. Similarly, the shoulder portion 11c is elastically deformed, and when the outer bottle 11 has a predetermined internal pressure, the folded portion 15 spreads and the flat portion 16 curves and elastically expands. However, the shoulder portion 11 c may have a substantially frusto-conical shape without providing the fold portion 15 and the flat portion 16. In that case, the shoulder 11 c may or may not elastically expand.

  A screw 11 d 1 for fixing the valve assembly 13 is formed on the outer periphery of the neck portion 11 d. An outer seal holding portion 11d2 is formed below the screw 11d1 for holding an outer seal member 18 for sealing between the outer bottle 11 and the valve assembly 13 (see FIG. 1). The outer seal holding portion 11d2 may be provided above the screw portion 11d1. Furthermore, under the screw 11d1 and the outer seal holding portion 11d2, there is formed an annular flange 11d3 for holding the outer bottle 11 at the time of assembly of the discharge container 10 or suspending the outer bottle 11 at the time of filling the undiluted solution C. . However, the outer peripheral structure of the neck portion 11 d is not particularly limited, and is appropriately determined according to a cap attached to the discharge product 10 or the like.

  As shown in FIG. 3a, the inner bottle 12 has a bottom 12a, a cylindrical body 12b, a tapered shoulder 12c whose diameter is reduced upward from the upper end of the body, and the upper end of the shoulder And a cylindrical neck 12d extending upwardly therefrom.

The inner bottle 12 has substantially the same shape as the inner surface of the outer bottle 11. Specifically, the bottom 12a has a hemispherical shape continuous from the lower end of the body 12b. The body 12b is a regular octagonal cylinder, and the shoulder 12c is a regular octagonal frustum. That is, similarly to the outer bottle 11, eight inner bottle folded portions 21 extending up and down from the body 12b to the shoulder 12c are formed annularly at equal intervals, and an inner bottle flat portion between the inner bottle folded portions 21 22 are provided (see FIG. 3b). An outwardly projecting flange portion 12d1 is formed on the upper end of the cylindrical neck portion 12d. The neck 12 d is inserted along the neck 11 d of the outer bottle 11.
The bottom 12a, the body 12b and the shoulder 12c of the inner bottle 12 are flexible, and the neck 12d is rigid. Then, an inner sealing material 19 for sealing between the inner bottle 12 and the valve assembly 13 is provided on the inner surface of the rigid neck 12 d of the inner bottle 12 (see FIG. 1).

  A plurality of vertically formed longitudinal passage grooves 12P formed continuously and vertically are formed annularly at equal intervals from the lower surface of the flange portion 12d1 of the inner bottle 12 to the outer surface of the upper end of the shoulder portion 12c via the outer surface of the neck portion 12d. Arranged (see FIG. 3a). The vertical passage groove 12P serves as a passage for the stock solution C connecting the first storage chamber S1 and the valve assembly 13. The vertical passage groove 12P may be provided on the inner surface of the neck portion 11d of the outer bottle 11, or on both the inner surface of the neck portion 11b of the outer bottle 11 and the outer surface of the neck portion 12b of the inner bottle 12. May be A passage may be formed to connect at least the first accommodation chamber S1 and the outside air (the valve assembly 13).

The inner bottle 12 is inserted coaxially with the outer bottle 11 so that the flange portion 12d1 is disposed at the upper end opening of the outer bottle 11 (see FIG. 1).
Then, when the stock solution C is filled in the first storage chamber S1, the bottom 12a, the body 12b, and the shoulder 12c of the inner bottle shrink and deform so that the volume of the inner bottle 12 decreases (broken line in FIGS. 1 and 3b reference). In addition, in FIG. 1, FIG. 3 b, although the shrinkage | contraction shape of the inner bottle 12 is described regularly, it shows an outline and is not limited. The contraction shape of the inner bottle 12 is irregularly deformed according to the filling path of the stock solution C, the viscosity of the stock solution C, the filling pressure of the stock solution C, and the like. However, by providing the inner bottle folding portion 21, it can be controlled so as to be preferentially folded along the inner bottle folding portion 21. Then, the inner bottle folding portion 21 exerts a rib effect on the inner bottle 12 to prevent the inner bottle 12 from being broken into the upper and lower two.
On the other hand, when the stock solution C in the first storage chamber S1 is discharged, the bottom 12a, the body 12b, and the shoulder 12c of the inner bottle are expanded and deformed so that the volume of the inner bottle 12 is increased. Finally, the outer surface of the bottom 12a, the body 12b and the shoulder 12c of the inner bottle 12 abuts on the inner surface of the bottom 11a, the body 11b and the shoulder 12c of the outer bottle 11, respectively. Return the prototype (see FIG. 6). Therefore, the first storage chamber S1 can be contracted efficiently. The neck 12 d is inserted along the inner surface of the neck 11 d of the outer bottle 11 and does not deform due to the filling and discharging of the stock solution C. Therefore, the vertical passage groove 12P is always secured.

  In addition, if the bottom 12a, the body 12b and the shoulder 12c of the inner bottle are deformed toward the inner surface of the bottom 11a, the body 11b and the shoulder 11c of the outer bottle 11 by discharging the stock solution C, respectively. The inner bottle 12 may have an outer shape and an inner shape of the outer bottle 11. For example, the inner bottle 12 may be smaller than the inner surface shape of the outer bottle 11. In that case, by discharging the undiluted solution C, the bottom 12a, the body 12b, and the shoulder 12c expand to the substantially same shape as the inner surface of the bottom 11a, the body 11b, and the shoulder 11c of the outer bottle 11 (elasticity Or plasticity). Further, the inner bottle folded portion 21 may or may not be provided in the inner bottle 12.

Examples of the material of the outer bottle 11 include synthetic resins such as polyethylene terephthalate, polyethylene, polypropylene and nylon.
Materials for the inner bottle 12 include synthetic resins such as polyethylene terephthalate, polyethylene and polypropylene, urethane-based, ester-based, styrene-based, olefin-based, butadiene-based and fluorine-based elastomers, silicone rubber, urethane rubber, isoprene rubber, ethylene Examples thereof include rubbers such as propylene rubber, ethylene propylene diene rubber, styrene butadiene rubber and mixed materials thereof.
The combination of materials of the outer bottle 11 and the inner bottle 12 can be appropriately selected according to the application.

As shown in FIG. 4a, the valve assembly 13 has a first in-valve passage 13a communicating the first storage chamber S1 with the outside, and an in-valve first passage communicating the inside of the inner bottle (the second storage chamber S2) with the outside. It is a lid provided with a two-passage passage 13b and a valve mechanism 25 for communicating / blocking the in-valve first passage 13a and the in-valve second passage 13b. The in-valve first passage 13a communicates with the first accommodation chamber S1 via the vertical passage groove 12P. However, the structure of the valve assembly 13 is not particularly limited as long as it includes at least a first in-valve passage communicating with the longitudinal passage groove 12P and a valve mechanism communicating / blocking the first in-valve passage. . In addition, although the valve assembly 13 is detachably fixed to the outer bottle 11, it may be fixed by welding or the like and may not be detachable.
As shown in FIG. 4b, the valve mechanism 25 includes two independent first in-stem passages 26a (part of the first in-valve passage 13a) to second in-the-stem passages 26b (part of the second in-valve passage 13b). ) Is provided. By depressing the stem 26, both passages in the valve communicate with the storage chambers S1 and S2. As such a stem 26, a push button 14 is used which communicates the first in-stem passage 26a with the outside air and blocks the second in-stem passage 26b. However, two stems may be used to connect / disconnect the respective in-valve first passage and the in-valve second passage.

The manufacturing method of this discharge product 10 prepares the double bottle which accommodated the inner bottle 12 in the outer bottle 11 first (refer FIG. 5 a). Although the inner bottle 12 is shrunk in the outer bottle 11 in FIG. 5a, the inner bottle 12 may not be shrunk in the prepared double bottle. After the inner bottle 12 is shrunk, it is easy to control the shrunk shape of the inner bottle 12 by filling the next stock solution C.
The valve assembly 13 is then attached to the double bottle outer bottle 11. Then, the stem 26 of the valve assembly 13 is pushed down, and the stock solution C is filled into the first storage chamber S1 via the first in-valve passage 13a of the stem 26 (see FIG. 5c). Further, the stem 26 of the valve assembly 13 is pushed down, and the propellant P is charged into the inner bottle 12 through the second in-valve passage 13b of the stem 26 (see FIG. 5e). Finally, the push button 14 is attached to the stem 26. The order in which the stock solution C and the propellant P are filled may be reversed. In that case, the valve assembly 13 is attached to the outer bottle 11 of the double bottle, and the propellant P is filled into the second storage chamber S2, and the stem is pushed down to make only the first passage in the valve communicate with each other. Air may be discharged, and then the stock solution may be pressure-filled from the first passage in the valve. The stock solution C may be filled before attaching the valve assembly 13 to the outer bottle 11, and the propellant P may also be filled immediately before attaching the valve assembly 13 to the outer bottle 11.
By filling the propellant P, the outer bottle 11 is expanded via the inner bottle 12 and the stock solution C, and the angle of the folding portion 15 is expanded, and the flat portion 16 is elastically deformed to the curved surface 16 a protruding outward. .

As a manufacturing method of a double bottle, the method of respectively shape | molding the outer bottle 11 and the inner bottle 12, folding the inner bottle 12, and inserting in the outer bottle 11 is mentioned.
As another manufacturing method of the double bottle, a method of molding the outer bottle 11, inserting an inner preform for the inner bottle into the inside and blow molding the shoulder portion or less by using the inner surface of the outer bottle 11 as a mold The method of preparing the double preform which inserted the inner preform for inner bottles in the outer preform for outer bottles, and simultaneously molding the outer bottle 11 and the inner bottle 12 is mentioned. In this case, an inner preform in which the flange portion 12d1 and the longitudinal passage groove 12P are formed in the neck portion 12d, and an outer preform in which the screw 11d1, the outer seal holding portion 11d2 and the annular flange 11d3 are formed in the neck portion 11d are used. When this manufacturing method is used, the outer shape of the inner bottle 12 can be shaped to be in contact with the inner surface of the outer bottle 11, that is, substantially the same shape as the inner surface of the outer bottle 11 (see FIG. 5g).

In the method of using the discharge product 10, the stem 26 of the valve assembly 13 is depressed via the push button 14. As a result, the first in-stem passage 26a of the stem 26 is opened, and the stock solution C is discharged. At this time, since the second in-stem passage 26b of the stem 26 is closed by the push button 14, the pressurizing agent P is not jetted (see the push button 14 in FIG. 6).
By discharging the stock solution C in this manner, the inner bottle 12 expands in proportion to the discharge amount of the stock solution C. In particular, when compressed gas is used as the propellant P, the pressure in the outer bottle 11 drops due to the discharge of the undiluted solution, whereby the elastic expansion is gradually released and contracted, and the angle of the fold 15 is narrowed. Therefore, even if the inner bottle 12 is expanded to the vicinity of the inner surface of the outer bottle 11, a gap is easily formed between the groove 15a (see FIG. 2b) of the inner surface of the outer bottle 11, and the gap is the first storage chamber S1. Acts as a passage connecting the two and the vertical passage groove 12P. In addition, the elastic deformation of the folded portion 15 and the flat portion 16 is also gradually released by the pressure reduction and the release of the elastic expansion accompanying the discharge of the stock solution C described above. Therefore, the appearance of the outer bottle 11 can be changed according to the remaining amount of the undiluted solution C. Since the neck 12d of the inner bottle 12 is hard, the vertical passage groove 12P is in fluid communication with the clearance passage to the end, and the first accommodation chamber S1 and the valve assembly 13 are always in communication. When the volume of the first storage chamber S1 decreases and the entire amount of the stock solution C is discharged, the inner bottle 12 is in contact with the inner surface of the outer bottle 11 because it has flexibility (see FIG. 6). Even in this state, the elastic expansion of the outer bottle 11 is maintained without being completely eliminated by the pressure of the propellant in the inner bottle 12.

  After the entire amount of the stock solution C is discharged (after use), the propellant P in the inner bottle 12 can be discharged to the outside through the second in-valve passage 13b by removing the push button 14 and depressing the stem 26. it can. By discharging the propellant P, the elastic expansion of the outer bottle 11 is released, and the outline and the flat portion 16 of the folded portion 15 of the outer bottle 11 appear clearly. Thus, the user can confirm that the propellant P has been completely discharged. Therefore, the user can safely remove the valve assembly 13 from the outer bottle 11. Finally, the outer bottle 11, the inner bottle 12 and the parts of the valve assembly 13 can be separated.

  In the discharge product 10 of FIG. 1, the barrel portion 11b of the outer bottle 11 is a regular octagonal cylinder, but before and after the filling of the propellant P, the folded portion 15 elastically deforms, the appearance looks different, and extends vertically. The shape is not particularly limited as long as it is a cylindrical body having a folded portion. Further, in the case where the body portion 11 b is a polygonal cylinder, the flat portion 16 may not be curved. As the folded portion 15, 4 to 16, preferably 5 to 12 are preferable. However, it is not particularly limited. Furthermore, the portion between the fold 15 and the fold 15 may not be a flat portion. For example, as shown in the outer bottle 11 of FIG. 2c, the inner curved surface 16b gently protrudes inward, and when the outer bottle has a predetermined internal pressure, it elastically deforms to the outer curved surface 16a protruding outward. It is good also as things. In this case, the change in the appearance of the flat portion 16 before and after the filling of the propellant P becomes more remarkable.

  The discharged product 30 shown in FIG. 7 has an outer bottle 31 provided with eight grooves 35 formed of three folds at regular intervals in a ring shape. Specifically, the outer bottle 31, the flexible inner bottle 32 accommodated in the outer bottle 31, the valve assembly 13 attached to the outer bottle 31 and closing the outer bottle 31 and the inner bottle 32, the outer bottle 31 and the inner The undiluted solution C stored in the cylindrical first storage chamber S1 between the bottle 32 and the propellant P stored in the inner bottle 12 (second storage chamber S2) are provided. The valve assembly 13 and the push button 14 are substantially the same as the dispensed product 10 of FIG.

In the outer bottle 31, as shown in FIG. 8a, eight groove strips 35 extending up and down from the body 11b to the shoulder 11c are annularly formed at equal intervals. The groove 35 and the groove 35 form a flat portion 16 (see FIG. 8 b). Therefore, in a state in which the internal pressure is not provided, the body portion 11b is a substantially regular octagonal cylinder, and the shoulder portion 11c is a substantially regular octagonal frustum. The other configuration is substantially the same as the outer bottle 11 of the discharge product 10 of FIG. 1 and comprises a bottom 11a, a body 11b, a shoulder 11c and a neck 11d.
The groove strip 35 is composed of two groove walls 35 a extending inward and connecting respectively from two adjacent flat portions 16. Therefore, the groove strip 35 is provided with a total of three folds 36 (cross-sectional W-shape) between the flat portion 16 and the groove wall 35a and between the connection portion of the two groove walls 35a. Then, the groove strips 35 elastically deform the outer bottles 31 so that the angles of the folds 36 thereof expand at a predetermined internal pressure.
That is, as shown by the broken line in FIG. 8b, the groove portion 35 and the flat portion 16 are elastically deformed at a predetermined internal pressure, and the trunk portion 11b approaches a substantially cylindrical shape as a whole. As described above, by forming the groove formed of a plurality of folds, the body portion 11b can be expanded more, and the change in the appearance of the outer bottle 11 before and after the filling of the propellant P can be increased. Furthermore, since the inner surface shape of the groove 35 also becomes complicated, when the inner bottle 32 expands, a gap is easily formed between the inner surface of the groove 35 and the outer surface of the inner bottle 32, and the stock solution C is not easily clogged.

  The inner bottle 32 has substantially the same shape as the inner surface of the outer bottle 31, as shown in FIG. Similar to the outer bottle 31, eight inner bottle groove stripes 37 extending up and down from the body 12b to the shoulder 12c are formed at equal intervals annularly, and the inner bottle flat portion 22 is formed between the inner bottle groove stripes 37. Is formed. The other configuration is substantially the same as the inner bottle 12 of the discharge product 10 of FIG. 1, the neck 12d is rigid, and the shoulders 12c and below are flexible.

  In this discharged product 30, too, the outer bottle 11 has the folds 36 (grooves 35), so that the propellant P is stored (the outer bottle has a predetermined internal pressure) as in the discharged product 10. Since the appearance changes between the state where the internal pressure is not held and the state where the internal pressure is not provided, the user can safely perform the disposal work. In addition, when using the propellant P composed of compressed gas, the internal pressure decreases with the discharge of the stock solution C, so that the elastic expansion of the outer bottle 11 is also gradually released. Therefore, the remaining amount of the undiluted solution C can be known from the appearance of the discharged product 30.

The discharge product 40 of FIG. 10 is a dual aerosol type discharge product in which the storage positions of the discharge product 10, the stock solution C, and the propellant P are reversed. That is, the propellant P is stored in the first storage chamber S1, and the stock solution C is stored in the second storage chamber S2. Then, as the push button 41, one that shuts off the first in-stem passage 26a and communicates with the second in-stem passage 26b is used. The other configuration is substantially the same as the discharge product 10 of FIG. 1 and comprises an outer bottle 11, an inner bottle 12 and a valve assembly 13.
Also in the discharged product 40, since the outer bottle 11 has the folding portion 15, a state in which the propellant P is stored (a state in which the outer bottle has a predetermined internal pressure) and a state in which the propellant P is not stored The appearance of the outer bottle 11 changes between (the state without the internal pressure) (broken line in FIG. 10 b). Therefore, disposal work can be done safely. Further, by using the propellant P as compressed gas, the internal pressure of the outer bottle 11 decreases with the discharge of the stock solution C, and the elastic expansion of the outer bottle 11 is gradually released. The appearance of the bottle 11 changes.
