Description

The present invention relates to a multiple-dispensing container equipped with multiple container bodies.

Aerosol containers (dispensing containers) in which the contents are stored in the container body together with a propellant such as liquefied gas are known. Aerosol containers are often used as dispensing containers for hair dyes in which a first liquid and a second liquid are mixed and used. For example, Patent Document 1 discloses a double aerosol container (multiple dispensing container) in which two container bodies are arranged side by side and bound together. This double aerosol container is provided with an actuator equipped with a discharge lever, a nozzle, etc., and when the discharge lever is pressed down, the stem inserted into each container body is pushed in, which opens the valve attached to the stem, and the force of the propellant causes the contents stored in each container to be ejected from the nozzle outlet at the same time.

Aerosol containers are often fitted with an overcap to prevent erroneous operation of the discharge lever during distribution, etc. The top surface of the overcap is also used as the suction surface of the suction conveyor used in the manufacturing process. The actuator transported by the suction conveyor is filled with the contents and transported above the container bodies arranged side by side, and the actuator is attached to the mouth of the container body to manufacture the product.

JP 2015-9863 A

In this type of multiple dispensing container, each container body is elongated in the axial direction, and the bottom area of the mounting surface is small relative to the axial length. Also, since multiple container bodies are arranged side by side in the left-right direction, the multiple dispensing container as a whole is wide in the left-right direction and thin in the front-to-back direction (depth direction). And since the actuator is located at the top, the center of gravity of the container itself is located at the top. Therefore, when the remaining amount of contents becomes low, for example, as shown in Figure 9, when a force is applied in the front-to-back direction, even if it is a light force, the multiple dispensing container is likely to tip over in the front-to-back direction. Note that Figure 9 shows an example of a conventional multiple dispensing container 200.

When the contents are hair dye or the like, if the dispensing container falls over during use, the contents adhering to the discharge port may soil the support surface. One way to prevent the multiple dispensing container from falling over is to place the barrel of each container body on the support surface with the container turned sideways. However, this requires the multiple dispensing container to be lifted each time the contents are dispensed, which makes it difficult to use, and there is also the risk that the support surface will be soiled by the contents adhering to the vinyl gloves, etc., if hands wearing vinyl gloves, etc., touch the support surface when lifting the multiple dispensing container.

Therefore, it is necessary to consider a container shape that will prevent the multiple discharge container from tipping over when placed in an upright position, but this must not significantly change the overall shape of the container or increase the number of parts. The objective of this invention is to provide a multiple discharge container that can be stably placed in an upright position without significantly increasing the container shape or number of parts compared to conventional multiple discharge containers.

In order to solve the above problems, the multiple dispensing container according to the present invention is a multiple dispensing container comprising a plurality of bottomed cylindrical container bodies, a dispensing head section that is provided on top of the container bodies when the container bodies are arranged side by side and that dispensing the contents contained in each container body from the dispensing port, and a removable overcap that covers the top of the dispensing head section, the overcap comprising a cap body having a lid surface section that covers the top of the dispensing head section, and a protruding section that is on the outside of the cap body and protrudes in a direction that intersects with the direction in which the container bodies are arranged side by side, the cap body is configured to be attachable to the bottom of the container body, and when the cap body is attached to the bottom of the container body, at least a portion of the protruding section is flush with the lid surface section.

In the multiple dispensing container according to the present invention, it is preferable that the protrusion has an inversion piece that forms part of the lid surface portion, is provided so as to be invertible with respect to the cap body, protrudes outside the cap body when inverted, and has a surface that is flush with the lid surface portion.

In the above case, it is also preferable that the cap body and the inverted piece are provided with an engaging portion and an engaged portion for releasably engaging with the cap body when the inverted piece is inverted.

In the multiple discharge container according to the present invention, it is also preferable that the protruding head portion has a nozzle portion that protrudes in a direction intersecting the arrangement direction of the container body, and when the overcap is attached to the top of the discharge head portion, the protruding portion covers the top of the nozzle portion.

In the multiple dispensing container according to the present invention, it is also preferable that the protrusions are provided on the outside of the cap body, on both sides in a direction intersecting the direction in which the container bodies are arranged side by side.

The multiple discharge container according to the present invention is configured such that a plurality of bottomed cylindrical container bodies are arranged side by side, and a discharge head portion is provided on the top of the container bodies, and when the axial length of the container bodies is long, the center of gravity of the container itself is likely to be located upward. However, in the multiple discharge container according to the present invention, the cap body of the overcap, which is detachably attached to the top of the discharge head portion, can be attached to the bottom of the container body. The cap body is provided with a protruding portion that protrudes in a direction intersecting the direction in which the container bodies are arranged side by side. At least a part of the protruding portion is flush with the lid surface portion of the cap body. Therefore, when the cap body is attached to the bottom side of the container body and the multiple discharge container is placed on a placement surface, the protruding portion that protrudes outward of the cap body comes into contact with the placement surface together with the lid surface portion, and the contact area of the multiple discharge container with the placement surface can be increased in a direction intersecting the placement direction of the container bodies. Therefore, when the multiple discharge container is placed in an upright position, it can be stably placed on the placement surface, and the multiple discharge container can be prevented from falling over. Furthermore, with this invention, all that is required is to provide a protrusion on the cap body, which does not require significant changes to the shape of conventional multiple dispensing containers and also prevents an increase in the number of parts.

Hereinafter, one embodiment of a multiple discharge container according to the present invention will be described with reference to the drawings. Fig. 1 is a diagram showing a multiple discharge container 100 of this embodiment, (a) being a front view, and (b) being a side view of (a).
As shown in FIG. 1, the multiple discharge container 100 of this embodiment is a container body 10 arranged side by side and bound together. More specifically, FIG. 1 shows a double aerosol container in which two container bodies 10 are arranged side by side on the left and right. The multiple discharge container 100 includes a discharge head portion 20 as an actuator for discharging the contents contained in the container body 10, and an overcap 30 is detachably attached to the top of the discharge head portion 20. Hereinafter, the direction along the central axis O when the multiple discharge container 100 is placed on a placement surface in an upright position as shown in FIG. 1 is referred to as the axial direction, and in the axial direction, the side where the discharge head portion 20 is arranged is referred to as the upper side, and the bottom side (bottom surface portion 11 of the container body 10) of the multiple discharge container 100 is referred to as the lower side. The direction in which the container bodies 10 are arranged side by side is the width direction of the multiple discharge container 100, the direction perpendicular to the width direction is the front-rear direction, and the side where the discharge port 21b is located, i.e., the side where the contents are discharged, is the "front" side, and the opposite side is the "rear" side. The same is true for the overcap 30, where the side where the first protrusion 32 described below is located is the "front" side, and the opposite side is the "rear" side.

First, the configuration of the container body 10 will be described with reference to FIG. 1. Each container body 10 has the above-mentioned bottom surface portion 11, body portion 12, and a mouth portion (not shown), is configured as a bottomed cylinder, and all have the same shape. As shown in FIG. 1(a), in this embodiment, two container bodies 10 are connected with their body portions 12 arranged close to each other or in contact with each other so that their central axes are parallel. The central axes of the two container bodies 10 and the central axis O of the multiple discharge container 100 are parallel, and the central axis O of the multiple discharge container 100 is located between the two container bodies 10.

The container body 10 of this embodiment is configured as an aerosol container (aerosol can) that contains a propellant such as liquefied gas (LPG, DME, etc.) or compressed gas (nitrogen gas, carbon dioxide gas, etc.) together with the liquid contents, and is sealed by covering the mouth with a top wall. However, in relation to the present invention, the container body 10 may be configured as a double container or the like that includes an inner bag (inner layer body) having a storage space that reduces in volume as the contents decrease, and an outer bag (outer layer body) that stores the inner bag. In addition, the multiple discharge container according to the present invention is not limited to an aerosol container that discharges the contents by the force of the propellant, but may be a pump container that discharges the contents by using a pump mechanism.

Although not shown here, a stem is erected in the mouth of each container body 10 so that it can be pushed down while being biased upward. A discharge valve is provided on the stem, and the mouth of the container body 10 is closed when the stem is erected. When the head portion 21 attached to the stem is pushed axially downward relative to the container body 10, the discharge valve opens, and the contents in the container body 10 pass through the internal flow path of the head portion 21 and are discharged to the outside through the discharge port 21b. In this embodiment, the container body 10 contains different contents, such as a first liquid (oxidative dye and alkaline agent) and a second liquid (oxidizing agent) of a hair dye.

Next, the discharge head portion 20 will be described with reference to Figs. 1 to 3. Figs. 2(a) and (b) are cross-sectional views of the overcap 30 in the multiple discharge container 100 shown in Figs. 1(a) and (b), respectively. Fig. 3(a) is a top view of the multiple discharge container 100 when the overcap 30 is removed, and (b) is a top view of the multiple discharge container 100 when the overcap 30 is attached, showing a part of its inside (the discharge lever 22 and the vertical mating rib 34). Fig. 3(c) will be described later.

As shown in Figures 2 and 3(a), the discharge head unit 20 includes a discharge lever 22 for pushing the head unit 21 axially downward, and a cover body 23, and is configured as a so-called actuator.

The head portion 21 has a nozzle portion 21a that protrudes forward at approximately the center of the width of the multiple discharge container 100, and the tip of the nozzle portion 21a is a discharge port 21b for discharging the contents. The nozzle portion 21a is provided with flow paths that communicate with the internal flow paths of the head portion 21. The contents discharged from each container body 10 pass through these internal flow paths, join just before the outlet of the discharge port 21b, and are discharged to the outside.

As shown in FIGS. 2(a) and 2(b), the cover body 23 has a cylindrical side wall portion 23a and a top cover portion 23b provided on the upper portion of the side wall portion 23a.
The cover body 23 is equipped with an internal cover body (not shown) and is configured as an exterior cover body that is detachably attached to the internal cover body. At this time, the internal cover body is attached to the mouth of the container body 10, and the container body 10 is bound together in a state of being arranged in parallel. These configurations can be appropriately adopted from conventionally known configurations.

As shown in Figures 2(a) and (b), the body 12 of the container body 10 arranged in parallel is inserted into the lower end of the side peripheral wall 23a, and the upper part of the body 12 of the container body 10 is covered by the cover body 23. The head portion 21 is housed inside the side peripheral wall 23a. A nozzle opening 23c is formed in the front surface of the side peripheral wall 23a, and the nozzle portion 21a is arranged to protrude forward from this nozzle opening 23c.

The top cover portion 23b is connected to the upper portion of the side peripheral wall portion 23a and is a generally dome-shaped cover body that covers the top surface side of the side peripheral wall portion 23a. In the top view shown in FIG. 3(a), a recess 23d that is open at the rear is provided at approximately the center in the width direction of the top cover portion 23b, and the discharge lever 22 is housed in the recess 23d so that it can be depressed. In addition, in the top view shown in FIG. 3(a), the front side of the top cover portion 23b is a recess 23e that is recessed inward.

Next, the overcap 30 will be described. As shown in Figs. 1 to 4, the overcap 30 detachably covers the upper part of the discharge head 20, i.e., the top part of the multiple discharge container 100. The overcap 30 has a cap body 31 having a cover surface part 31a that covers the top part of the multiple discharge container 100 and a peripheral wall part 31b that is vertically attached from the outer edge of the cover surface part 31a, a first protrusion part 32 that protrudes outward from the cap body 31, and an inverted piece 40 that forms part of the cover surface part 31a. The inverted piece 40 is connected to the cap body 31 in a reversible manner as shown in Figs. 5(a) and (b). When the inverted piece 40 is inverted, the inverted piece 40 protrudes outward from the cap body 31 and functions as a second protrusion part.

The cover surface portion 31a has a rounded rectangular shape in top view as shown in Fig. 4(a) and a thin plate shape in side view as shown in Fig. 4(b). A fitting vertical rib 34 shown in Fig. 4(b) is provided on the underside of the cover surface portion 31a so as to protrude downward.
In this embodiment, the fitting vertical ribs 34 are formed in the shape of a long plate in the axial direction, and four fitting vertical ribs 34 are provided on the lower surface of the cover surface portion 31a as shown in Fig. 3(b). As shown in Fig. 2(a) and Fig. 3(b), these fitting vertical ribs 34 are inserted into the recesses 23d and 23e of the top cover portion 23b, and are arranged not to interfere with the discharge lever 22 when the overcap 30 is attached to the discharge head portion 20.

1, the first protrusion 32 has a shape like an upside-down T-shape in front view. In detail, the first protrusion 32 has a covering portion 32a having a substantially rectangular flat plate shape in top view as shown in FIG. 4(a), and a vertical rib portion 32b standing on the upper surface of the covering portion 32a at a substantially central position in the width direction. As shown in FIG. 1, when the overcap 30 is attached to the ejection head portion 20, the covering portion 32a is located above the nozzle portion 21a with a predetermined distance from the upper surface of the nozzle portion 21a, and covers the upper portion of the nozzle portion 21a. As shown in FIG. 1 and FIG. 4(a) and (b), the vertical rib portion 32b has a thin plate shape with a small thickness in the width direction in front view and a predetermined length in the front-rear direction. The upper end surface of the vertical rib portion 32b is flush with the upper surface of the cover surface portion 31a. In addition, the rear end side of the vertical rib portion 32b is joined to the peripheral wall portion 31b of the cap body 31.

Here, the upper end surface of the vertical rib portion 32b and the upper surface of the lid surface portion 31a being "flush" means that the axial height position of the upper surface of the lid surface portion 31a and the axial height position of the upper end surface of the vertical rib portion 32b match. In this embodiment, the vertical rib portion 32b is joined to the peripheral wall portion 31b of the cap body 31, so the upper end surface of the vertical rib portion 32b and the upper surface of the lid surface portion 31a are continuous. However, the two do not necessarily have to be continuous, and there may be a recess or gap between them, and there may be a portion where the height of the two surfaces is discontinuous. However, it is assumed that there is no protrusion protruding axially upward between the upper end surface of the vertical rib portion 32b and the upper surface of the lid surface portion 31a. In other words, assuming that there is a flat reference surface (imaginary surface) that abuts against the upper surface of the lid surface portion 31a and that this reference surface is substantially horizontal, it is sufficient that the upper surface of the lid surface portion 31a and the upper end surface of the vertical rib portion 32b can abut against this reference surface at the same time, and that even if the upper surface of the lid surface portion 31a and the upper end surface of the vertical rib portion 32b abut against this reference surface at the same time, the reference surface does not tilt and can remain substantially horizontal.

Next, the configuration of the inverted piece 40 will be described with reference to Figures 4 and 6. Figure 6(a) is an enlarged perspective view of the portion of the overcap 30 where the inverted piece 40 is provided. In Figure 6(a), the surface extending in the axial direction is hatched in order to make the shape of the inverted piece 40 easier to understand. Also, Figure 6(b) is an enlarged view of the circled portion in Figure 4(a). However, Figure 6(b) shows the corresponding portion in Figure 4(a) rotated 90 degrees. As shown in Figures 4(a) and 6(a), the inverted piece 40 is elongated in the front-rear direction, has both corners on the front end side rounded, and is formed in a tongue shape connected to the cap body 31 at the rear end side. An opening 33 shaped along the outer edge of the inverted piece 40 is formed in the cover surface portion 31a, and the inverted piece 40 is disposed within this opening 33. A gap is provided between the outer peripheral surface 40a of the inverted piece 40 and the inner peripheral surface 33a of the opening 33. The reversible piece 40 can be reversed from a first position forming part of the cover surface portion 31a to a second position shown in Fig. 5. Here, as shown in Fig. 4(b), when the surface (upper surface) facing the same direction as the upper surface of the cover surface portion 31a in the first position is the top surface 40b, and the opposite surface (lower surface) is the back surface 40c, reversing the reversible piece 40 from the first position to the second position means that, as shown in Figs. 5(a) to (c), in the second position, the top surface 40b of the reversible piece 40 faces downward and the back surface 40c faces upward, so that the top and bottom are reversed.

As shown in Figs. 5(a) to (c), when the inverted piece 40 is inverted, the inverted piece 40 protrudes to the rear of the cap body 31. At this time, the upper surface of the lid surface portion 31a and the back surface 40c of the inverted piece 40 are flush with each other. In this case, the term "flush" is the same as above, and it is sufficient that the upper surface of the lid surface portion 31a and the back surface 40c of the inverted piece 40 can simultaneously abut on the reference surface when a flat reference surface (imaginary surface) that abuts on the upper surface of the lid surface portion 31a exists and the reference surface is substantially horizontal, and even if the upper surface of the lid surface portion 31a and the back surface 40c of the inverted piece 40 abut on the reference surface simultaneously, the reference surface does not tilt and can be maintained substantially horizontal. Note that the back surface 40c of the inverted piece 40 and the upper surface of the lid surface portion 31a are flush with each other through the opening 33.

Next, the configuration of the inverted piece 40 will be described in more detail with reference to FIG. 6. FIG. 6(a) shows the inverted piece 40 in the first position, in an uninverted state. The inverted piece 40 has, in the front-rear direction, an inverted protrusion 41, an engagement portion 42, a joint portion 43, and a bent portion 44, in that order from the front.

The inverted protrusion 41 forms part of the lid surface portion 31a, and the thickness of the lid surface portion 31a and the thickness of the inverted protrusion 41 are formed to be the same. When the inverted piece 40 is inverted, the inverted protrusion 41 protrudes to the rear of the cap body 31. In addition, the top surface 40b of the inverted piece 40 described above corresponds to the upper surface of the inverted protrusion 41, and the back surface 40c of the inverted piece 40 corresponds to the lower surface of the inverted protrusion 41.

The engaging portion 42 is connected to the inverted protrusion 41. As shown in FIG. 6(a), the engaging portion 42 has engaging protrusions 42a that protrude outward in the width direction from both sides of the inverted protrusion 41. As shown in FIG. 4(a), the engaging protrusions 42a are semicircular in top view, with the arc portions protruding outward. The thickness of the engaging protrusions 42a is about 1/3 to 1/2 the thickness of the inverted protrusion 41, and the upper surface of the engaging protrusions 42a is flush with the upper surface of the inverted protrusion 41. As shown in FIG. 4(c) which is an enlarged view of a portion of FIG. 4(b), the engaging portion 42 has a first vertical surface portion 42b extending approximately parallel to the axial direction in a cross-sectional view, and a flat surface portion 42c extending approximately perpendicular to the axial direction. The upper surface of the flat surface portion 42c is located axially lower than the upper surface of the inverted protrusion 41, and the thickness of the flat surface portion 42c is thinner than the thickness of the inverted protrusion 41. In other words, there is a step between the top surface of the inverted protrusion 41 and the top surface of the flat surface 42c, and there is also a step between the top surface of the engagement protrusion 42a and the flat surface 42c.

The joint 43 joins the engagement portion 42 and the bent portion 44. As shown in Figs. 4(c) and 6(a), the upper and lower surfaces of the joint 43 are inclined. The thickness of the joint 43 becomes thinner from the engagement portion 42 toward the bent portion 44.

The thickness of the bent portion 44 in the inverted piece 40 is the thinnest, and it is configured to be easily bent. The bent portion 44 is connected to the rear end of the cap body 31. Therefore, for example, when the back surface of the inverted protrusion 41 (the back surface 40c of the inverted piece 40) is pressed upward with a finger or the like from the underside of the cover surface portion 31a, the bent portion 44 bends at approximately the center position of the bent portion 44 in the front-rear direction, and the inverted protrusion 41 can be inverted. In other words, the bent portion 44 functions as a hinge portion that connects the inverted protrusion 41 to the cap body 31 in an invertible manner. The rear end side of the bent portion 44 is configured to be thick, and is connected to the support portion 35 that protrudes from the upper end side of the peripheral wall portion 31b toward the underside of the rear end of the bent portion 44.

Incidentally, the rear end portion of the opening 33 formed in the cover surface portion 31a, and the upper end portion of the peripheral wall portion 31b, are configured as an engaged portion with which the engaging portion 42 of the inverted piece 40 engages. Specifically, they are configured as follows. First, as shown in Figures 4(a), (c) and 6(a), (b), the inner peripheral surface 33a of the opening 33 is provided with a convex portion 33b that protrudes inwardly of the opening 33. In addition, the rear end side of the bent portion 44 is provided with a second vertical surface portion 44a that extends approximately parallel to the axial direction, and at a position facing the opening 33 of the peripheral wall portion 31b, the upper end surface of the peripheral wall portion 31b is at the same height position in the axial direction as the back surface 40c of the inverted piece 40 (see Figure 4(c)). By configuring the rear end portion of the opening 33 in this manner, as shown in FIG. 5, when the inverted piece 40 is inverted and the engagement portion 42 is pushed axially downward, the first vertical surface portion 42b faces the second vertical surface portion 44a, and the flat surface portion 42c faces the upper end surface of the peripheral wall portion 31b, and the engagement protrusion portion 42a is pushed downward into the protrusion portion 33b, so that the engagement portion 42 engages with the cap body 31. On the other hand, as shown in FIG. 5, when the inverted piece 40 is in the inverted second position, the downward-facing top surface 40b is pushed upward, so that the engagement protrusion portion 42a overcomes the protrusion portion 33b and the engagement state is released. This allows the inverted piece 40 to be returned to its original first position.

The overcap 30 configured in this manner can be attached to the bottom of the multiple discharge container 100, as shown in Figures 7 and 8. In this embodiment, the multiple discharge container 100 has two container bodies 10. When the overcap 30 is attached to the bottom of the multiple discharge container 100, the bottom surface portions 11 of the container bodies 10 are placed on the back surface of the lid surface portion 31a, and each container body 10 is fitted together by the peripheral wall portion 31b and the fitting vertical rib 34. The underside of the multiple discharge container 100 when the overcap 30 is attached to the bottom of the multiple discharge container 100 is shown in Figure 3(c).

As shown in FIG. 3(c) and FIG. 5(a)-(c), when the reversing piece 40 is inverted, the first protrusion 32 and the reversing piece 40 each protrude in the front-rear direction. In addition, the upper end surface of the vertical rib portion 32b of the first protrusion 32, the upper surface of the lid surface portion 31a, and the back surface 40c of the reversing piece 40 are flush with each other. Therefore, when the overcap 30 is attached to the bottom of the multiple discharge container 100 and the multiple discharge container 100 is placed on a mounting surface, the first protrusion 32 and the reversing piece 40 come into contact with the mounting surface together with the lid surface portion 31a as shown in FIG. 7 and FIG. 8, and the contact area between the multiple discharge container 100 and the mounting surface can be increased in a direction substantially perpendicular (intersecting) to the arrangement direction of the container body 10. Therefore, when the multiple discharge container 100 is placed in an upright position, it can be stably placed on the mounting surface, and the multiple discharge container 100 can be prevented from falling over.

In contrast, in the case of a conventional multiple discharge container 200 as shown in FIG. 9, the center of gravity of the multiple discharge container 200 itself is located at an upper position, so that when a force is applied in the front-to-rear direction, even a light force, the multiple discharge container 200 is likely to tip over in the front-to-rear direction. Therefore, as shown in FIG. 9, for example, when a force is applied to the multiple discharge container 200 pushing it backward in the front-to-rear direction, the multiple discharge container 200 is likely to tip backward. In particular, as the amount of content remaining decreases, the multiple discharge container 200 is more likely to tip over. When the content is a hair dye or the like, if the multiple discharge container 200 tips forward during use, the content adhering to the discharge port 21b may soil the placement surface. However, although the multiple discharge container 100 of the above embodiment has a configuration substantially similar to that of the conventional multiple discharge container 200, the overcap 30 having the first protrusion 32 and the reversible piece 40 is attached to the bottom, and the multiple discharge container 100 can be prevented from tipping over by the simple method of keeping the reversible piece 40 inverted at that time.

In addition, in the above embodiment, the container body 10 and the discharge head portion 20 can be configured in common with the conventional multiple discharge container 200 (see FIG. 9), and there is no need to change their configuration. In addition, the conventional multiple discharge container 200 also has an overcap to prevent erroneous operation of the discharge lever during distribution, etc., and to ensure an adsorption surface during adsorption and transport in the manufacturing process, and this makes it possible to suppress an increase in the number of parts compared to the conventional multiple discharge container 200. In addition, although the above overcap 30 has an inversion piece 40, it can be easily manufactured by resin molding using a mold, etc., so there is no increase in assembly man-hours during manufacturing.

Furthermore, in the above embodiment, when the overcap 30 is attached to the discharge head portion 20, the first protrusion 32 covers the top of the nozzle portion 21a, which can prevent, for example, inadvertent application of force to the nozzle portion 21a from above. On the other hand, the reversing piece 40 can be reversed only when the overcap 30 is attached to the bottom of the multiple discharge container 100, and if the reversing piece 40 is kept in the first position at other times, the reversing piece 40 can be prevented from protruding outside the cap body 31 and becoming bulky during distribution or storage.

(Modification)
Next, a modified example of the multiple discharge container 100 of the above embodiment will be described. As shown in Figures 1 to 8, the multiple discharge container 100 of the above embodiment is provided with an overcap 30 having a first protruding portion 32 and one reversible piece 40. However, the configuration of the overcap 30 is not limited to the aspect described in the above embodiment, and for example, an overcap 50 shown in Figures 10 and 11 may be adopted. In the following, elements having the same functions and configurations as the respective components described in the above embodiment will be given the same names, and their description will be omitted.

10 and 11, the overcap 50 has a cap body 51 and two inverted pieces 52 that protrude from the outer side of the cap body 51 on both sides in the front-rear direction. However, FIG. 10 shows the state where each inverted piece 52 is in the first position, and FIG. 11 shows the state where each inverted piece 52 is inverted and in the second position. The overcap 50 has substantially the same configuration as the overcap 30 of the above embodiment, except that the inverted piece 52 is used as the first protrusion instead of the first protrusion 32, and includes an engaging protrusion 52a, a protrusion 52b, a bending portion 52c, a fitting vertical rib 53, etc., which have the same configuration and function as the above-mentioned engaging protrusion 42a, a protrusion 33b, a bending portion 44, a fitting vertical rib 34, etc. In addition, each inverted piece 52 forms a part of the lid surface portion 51a, and an opening 54 is formed in the lid surface portion 51a along the outer shape of each inverted piece 52. The other parts are the same, and will not be described here.

Even in this modified example, when the overcap 50 is attached to the bottom of the multiple discharge container 100 with the reversible piece 52 inverted from the first position shown in FIG. 10, the reversible piece 52 comes into contact with the mounting surface together with the lid surface portion 51a as shown in FIG. 11. This increases the contact area of the multiple discharge container 100 with the mounting surface in a direction that is approximately perpendicular (intersecting) to the arrangement direction of the container bodies 10. Therefore, when the multiple discharge container 100 is placed in an upright position, it can be stably placed on the mounting surface, and tipping over of the multiple discharge container 100 can be prevented.

The embodiment described above is one aspect of the present invention, and the present invention is not limited to the above-mentioned multiple discharge container 100 and its modified examples, and can of course be modified as appropriate within the scope of the present invention. For example, in the above embodiment, a double-barreled aerosol container having two container bodies 10 is given as an example, but the number of container bodies 10 is not limited to two, and may be three or more. Also, as described above, it is not limited to an aerosol container. The specific configurations and shapes of the container body 10, discharge head portion 20, and overcap 30 (overcap 50) can be modified as appropriate within the scope of the present invention.

An overcap similar to the overcap 30 described above may also be applied to a discharge container (such as an aerosol container) that has a discharge head portion such as an actuator for one container body. If the body portion of the container body is long in the axial direction relative to the bottom area, the center of gravity of the container itself will be located at the top, as with the multiple discharge container 100 described above. Therefore, by providing an overcap similar to the overcap 30 described above, it is possible to prevent a discharge container with a center of gravity located at the top from tipping over.
