Description

[Technical Field]

[0001] The present invention relates to a multiple discharge container having a plurality of discharge container bodies. [Background technology]

[0002] BACKGROUND ART Dual-seat containers capable of simultaneously discharging two liquids, such as a cosmetic product and a hair dye, are known. For example, Patent Document 1 discloses a double-barreled container in which two container bodies are arranged side by side and bound together to form a double-barreled container body, and a nozzle head, which is a common component, is attached to the stems of the dispensers attached to each container body. With this double-barreled container, when the nozzle head is pressed down, the stems of both dispensers are simultaneously pushed into the inside of the container body, and the contents inside each container body are sucked up by the dispenser and dispensed from the discharge port provided in the nozzle head.

[0003] In the double-barreled container disclosed in Patent Document 1, pressing the nozzle head once allows the contents contained in each container body to be simultaneously dispensed in predetermined amounts. However, when the stems of both dispensers are pressed down by a single nozzle head, as in this double-barreled container, the contents contained in either container body cannot be dispensed independently.

[0004] Therefore, for example, Patent Document 2 proposes a duplex container in which two discharge containers, each with a dispenser and a nozzle head attached to its container body, are integrally mounted on a shoulder part, and a presser plate that can rotatably and vertically move relative to the shoulder part and can simultaneously press down both nozzle heads. According to the duplex container disclosed in Patent Document 2, by rotating the presser plate over both nozzle heads, both nozzle heads can be simultaneously pressed down by pressing down the presser plate. Furthermore, by rotating the presser plate and retracting it from the nozzle heads, each nozzle head can be pressed down individually. Therefore, according to the duplex container disclosed in Patent Document 2, two liquids can be discharged simultaneously or individually, as needed. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-301843 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-162222 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the multiple-barreled container described in Patent Document 2 has a nozzle head for pressing down the stem of each dispenser attached to the container body, and a presser plate for simultaneously pressing down both nozzle heads is rotatably mounted on the shoulder part, so the head configuration tends to be larger than the multiple-barreled container disclosed in Patent Document 1. If the head portion is large, it may be difficult to place your fingers on the nozzle head portion when holding the dual-barreled container, which may reduce operability. Furthermore, if the nozzle head portion is too large, it may also result in design constraints.

[0007] Therefore, the object of the present invention is to provide a multiple-type dispensing container that has multiple dispensing container bodies, which allows multiple contents to be dispensed individually or simultaneously, and which allows the nozzle head portion to be configured compactly. [Means for solving the problem]

[0008] In order to solve the above problems, the multiple container of the present invention comprises a container body for accommodating contents, a holding part for holding a plurality of discharge container bodies each having a discharger attached to the container body and activated when a stem is pressed against the container body, and a nozzle head having a discharge port for discharging the contents and arranged to be movable in the pressing direction of the stem relative to the holding part, wherein each discharge container body is connected to the nozzle head via each stem and is held by the holding part so as to be movable in the pressing direction, The dispenser is attached to the mouth of the container body via a mounting cap, the mounting cap having a flange portion protruding outward from its outer circumferential surface, and the holding portion having a flange receiving portion disposed below in the pressing direction with respect to a predetermined flange portion corresponding to a predetermined discharge container body selected from the plurality of discharge container bodies, When the nozzle head is pressed down, The aforementioned The present invention is characterized in that, while a predetermined discharge container body is fixed in the pushing direction, discharge container bodies other than the predetermined discharge container body are moved in the pushing direction.

[0010] In the multi-compartment container according to the present invention, the holding portion is a storage case that stores the container bodies in a parallel arrangement, and the storage case has a support wall portion that is arranged between adjacent container bodies and is arranged lower than the flange portion in the pushing-down direction, and it is preferable that the flange receiving portion is arranged between the support wall portion and the flange portion in the pushing-down direction and is rotatably arranged below the adjacent flange portions.

[0011] In the multiple container according to the present invention, it is preferable that the storage case is provided with an opening through which a portion of the flange receiving portion is exposed, and that the position of the flange receiving portion can be switched through the opening.

[0012] In the multiple container according to the present invention, the container body preferably has a storage space that reduces in volume as the contents decrease.

[0013] In the multi-compartment container according to the present invention, it is preferable that the container body is provided with a tubular housing portion provided within the mouth portion for housing the cylinder of the dispenser, and a suction tube connected to the tubular housing portion, and when the dispenser is attached to the mouth portion of the container body, the cylinder is housed in the tubular housing portion, and the inside of the container body and the inside of the cylinder are connected via the suction tube. [Effects of the Invention]

[0014] According to the multiple container of the present invention, a plurality of discharge container bodies each including a container body and a discharger attached to the opening of the container body are provided, and each discharge container body can accommodate a different content, thereby enabling the storage of a plurality of different contents. The nozzle head is connected to each discharger via the stem of each discharge container body. Each discharge container body is held by a holding portion so that it can move in the direction of depressing the stem. In this multiple container, when the nozzle head is pressed down, a selected, predetermined discharge container body is fixed, and the other discharge container bodies are moved in the direction of depressing the stem. Therefore, if all discharge container bodies are selected and the nozzle head is pressed down, all discharge container bodies are fixed in the direction of depressing relative to the holding portion, so that the stems are pushed into the dischargers and each discharger is activated. On the other hand, if only some of the multiple discharge container bodies are selected, the selected discharge container body is fixed in the direction of depressing relative to the holding portion, but the other discharge container bodies move in the direction of depressing relative to the holding portion together with the nozzle head. In this way, by selecting a specific discharge container body and pressing down the nozzle head, the discharger attached to the selected discharge container body is activated, causing the contents to be discharged from the discharge port provided in the nozzle head.

[0015] As described above, with the multiple container according to the present invention, it is not necessary to provide a nozzle head for each dispenser, and the nozzle head can be used as a common component for all dispensers, allowing multiple contents to be dispensed individually or simultaneously. Furthermore, since it is not necessary to provide a nozzle head for each dispenser, the nozzle head portion can be configured compactly. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] A dual-barreled container 100, which is an embodiment of a multiple-barreled container according to the present invention, will be described with reference to the drawings. The dual-barreled container 100 shown in Figures 1(a) and 1(b) is configured such that two discharge container bodies 20 (20A, 20B) are arranged side by side in a storage case 10 (holding portion), and by pressing a nozzle head 70 against the storage case 10, the contents stored in each discharge container body 20 can be discharged individually or simultaneously.

[0018] Specifically, each discharge container body 20 comprises a container main body 30 in which the contents are stored, and a dispenser 60 (see FIG. 5(b)) attached to the container main body 30 via an attachment cap 50. The dispenser 60 is configured as a pump mechanism that includes a stem 61 as well as a piston, a cylinder, etc. (not shown in FIG. 1). In the duplex container 100, the attachment cap 50 is provided with a flange portion 55 that protrudes outward from its outer circumferential surface, and the flange portion 55 is supported by a flange receiving portion 80 rotatably provided between each discharge container body 20 and a support wall 12 (see FIG. 2) provided within the storage case 10, whereby each discharge container body 20 is stored in a suspended state within the storage case 10. By rotating the flange receiving portion 80, it is possible to select the discharge container body 20 from which the contents are to be discharged, and by supporting only the flange portion 55 (55A) on the selected discharge container body 20 (the first discharge container body 20A in the example shown in Figure 1 (b)), the selected discharge container body 20 (20A) is fixed in the axial direction, and when the nozzle head 70 is pressed down, the other discharge container body 20 (the second discharge container body 20B) is moved axially downward within the storage case 10, so that when only one discharge container body 20 (for example, the first discharge container body 20A) is selected, the contents are discharged from only that one discharge container body 20 (20A), and when both discharge container bodies 20 (20A, 20B) are selected, the contents are discharged from both discharge container bodies 20 (20A, 20B).

[0019] Here, FIG. 1(a) is a top view of the duplex container 100, and FIG. 1(b) is a front view of the duplex container 100, showing the AA cross section of the container case 10 and nozzle head 70 in FIG. 1(a). 1(b), when the duplex container 100 is placed in an upright position, the discharge container body 20 arranged on the left side of the drawing is referred to as the first discharge container body 20A, and the discharge container body 20 arranged on the right side is referred to as the second discharge container body 20B. However, when there is no need to particularly distinguish between the first discharge container body 20A and the second discharge container body 20B, they will simply be referred to as the discharge container body 20. Similarly, when it is necessary to distinguish between the container body 30, the mounting cap 50, the flange portion 55, and the dispenser 60, they will be referred to as the first container body 30A (inner member 40A), the second container body 30B (inner member 40B), the first mounting cap 50A, the second mounting cap 50B, the first flange portion 55A, the second flange portion 55B, the first dispenser 60A, and the second dispenser 60B, but at other times they will simply be referred to as the container body 30, the mounting cap 50, the flange portion 55, and the dispenser 60.

[0020] In this embodiment, the direction along the central axes O1 and O2 of each container body 30 is referred to as the axial direction. The bottom side of the container body 30 in this axial direction is referred to as the "lower" side, and the side on which the nozzle head 70 is provided is referred to as the "upper" side. In the state shown in FIG. 1(b), the direction perpendicular to the axial direction and perpendicular to the front-to-rear direction, i.e., the direction in which the discharge container bodies 20 are arranged side by side, is referred to as the left-to-right direction. In this embodiment, the storage case 10 has an elongated cylindrical shape that is elongated in the left-to-right direction when viewed from above. The side on which the discharge port 71a of the nozzle head 70 is provided is referred to as the "front" side, and the opposite side is referred to as the "rear" side. The central axes of the storage case 10 in the front-to-rear and left-to-right directions are indicated by the symbol Ac in the drawings. The central axis Ac of the storage case 10 is parallel to the central axes O1 and O2 of each container body 30 and is located at the center of the central axes O1 and O2 of each container body 30 in the left-to-right direction. Each component will be described in detail below.

[0021] First, the storage case 10 will be described with reference to Figures 1 and 2. As shown in Figure 1(b), the storage case 10 has a case body 11 and a case cap 15, and stores a first discharge container body 20A and a second discharge container body 20B.

[0022] Fig. 2 is a diagram showing only the case body 11 shown in Fig. 1. Fig. 2(a) is a top view of the case body 11, (b) is an FF cross-sectional view of the case body 11 in (a), and (c) is a GG cross-sectional view of the case body 11 in (a). As shown in Figs. 2(b) and (c), the case body 11 has a bottom wall 11a and a case-side peripheral wall 11b erected from the outer edge of the bottom wall 11a, and the case body 11 has an elongated cylindrical shape as described above.

[0023] As shown in Fig. 1(b), a case cap 15 is inserted into the upper part of the case side peripheral wall 11b, and the case cap 15 is detachably engaged with the case main body 11. As shown in Figs. 2(b) and 2(c), a plurality of (two in this embodiment) circumferential engagement grooves 11c extending around the entire circumference are formed on the inner surface of the case side peripheral wall 11b at intervals in the up and down axial direction. The circumferential engagement grooves 11c engage with engagement protrusions 15a provided on the case cap 15 side, thereby detachably engaging the case cap 15 with the case main body 11 (see Figs. 1(b) and 3).

[0024] As shown in FIG. 2(a), the case-side peripheral wall 11b is provided with support walls 12 (support wall portions) that protrude inward in a substantially V-shape from the inner front and rear surfaces of the case-side peripheral wall 11b. The support walls 12 extend upright from the bottom wall 11a of the case main body 11 and are shaped like two support plate pieces 13 connected to the case-side peripheral wall 11b, combined to form a substantially V-shape in top view. The support walls 12 are provided at a central position in the left-right direction within the case-side peripheral wall 11b. As shown in FIG. 1(b), the case-side peripheral wall 11b is substantially partitioned by the support walls 12 to accommodate a first discharge container body 20A in one space, and a second discharge container body 20B in the other space. By providing the support walls 12 within the case main body 11, the discharge container bodies 20 can be stably held within the storage case 10. Furthermore, by accommodating each discharge container body 20 in a space substantially surrounded by the support wall 12 and the case-side peripheral wall 11b, it is possible to guide the movement of each discharge container body 20 in the axial direction.

[0025] As shown in Figures 2(b) and 2(c), the upper end of the support wall 12 is located axially higher than the upper end of the case body 11. The upper end portion 12a of the support wall 12 is shaped such that one side portion 13a of each support plate piece 13 is cut out so as to slope inward toward the inside of the case body 11 as it extends axially upward. A flange receiving portion 80 (see Figures 6(b), 7 to 9, etc.) abuts against the upper end portion 12a of the support wall 12. The function and the like of the flange receiving portion 80 will be described later.

[0026] Furthermore, by making the upper end portion 12a of the support wall 12 protrude beyond the upper end of the case body 11 while providing a space between it and the case side peripheral wall 11b, the case cap 15 can be easily attached and detached to the case body 11 even when the upper end portion 12a of the support wall 12 is positioned axially above the upper end of the case body 11.

[0027] Next, the case cap 15 will be described with reference to Fig. 3. Fig. 3 shows the configuration of the case cap 15 only, with (a) being a side cross-sectional view and (b) being a top view. As shown in Figure 3(a), the case cap 15 has an attachment portion 16 located at the bottom of the case cap 15 and attached to the case body 11, a nozzle head guide portion 17 located at the top of the case cap 15 for guiding the axial movement of the nozzle head 70, and a connecting portion 18 connecting the attachment portion 16 and the nozzle head guide portion 17.

[0028] As shown in Fig. 1(b) etc., the mounting portion 16 is inserted into the upper part of the case main body 11. As shown in Fig. 3(a), the two engaging protrusions 15a are provided on the outer surface of the mounting portion 16 at positions corresponding to the engaging circumferential groove 11c on the case main body 11 side, spaced apart from each other in the axial direction above and below.

[0029] 3(a) and 3(b), the connecting portion 18 is configured in a cylindrical shape with a top, and includes a main body cap peripheral wall portion 18a and an annular main body cap top wall portion 18b connected to the upper edge of the main body cap peripheral wall portion 18a. The nozzle head guide portion 17 is provided on the upper surface of the main body cap top wall portion 18b.

[0030] As shown in FIG. 3(a), a pivot shaft 19 that protrudes downward along the axial direction is provided on the underside of the main body cap top wall 18b. A bearing 81 of the flange receiver 80 is rotatably mounted on the pivot shaft 19. The pivot shaft 19 is provided on the front side of the connecting portion 18 (see FIG. 3(b)). The pivot shaft 19 is disposed at the top of a space surrounded by the pair of support plates 13 that constitute the support wall 12 and the case-side peripheral wall 11b on the front side of the housing case 10. A substantially rectangular opening 15b is provided on the rear side of the connecting portion 18. When the bearing 81 of the flange receiver 80 is mounted on the pivot shaft 19, a part of the flange receiver 80 (rear edge 83b) is positioned in the opening 15b, allowing a user to place a finger or the like on the flange receiver 80 through the opening 15b and rotate the flange receiver 80 (see FIGS. 4(b), 8, and 9).

[0031] 3(a) and 3(b), the nozzle head guide portion 17 includes an outer peripheral wall portion 17a erected on the upper surface of the main body cap top wall portion 18b, an inner peripheral wall portion 17b provided inside the outer peripheral wall portion 17a, and a top wall portion 17c connecting the upper ends of the outer peripheral wall portion 17a and the inner peripheral wall portion 17b. As shown in FIGS. 1(b), 4(b), 5(b), etc., the nozzle head 70 is inserted inside the inner peripheral wall portion 17b so as to be axially movable while attached to the stem 61.

[0032] Next, the discharge container body 20 will be described with reference to Figs. 4 and 5. Fig. 4(a) is a front view showing the appearance of the discharge container body 20. Fig. 4(b) is a side cross-sectional view of the duplex container 100 showing the discharge container body 20 housed in the housing case 10 and the nozzle head 70 attached to the stem 61 of the dispenser 60. Here, Fig. 4(b) shows the cross section BB of Fig. 1(a) and shows the state in which the flange receiving portion 80 is disposed between the first discharge container body 20A and the second discharge container body 20B (see Figs. 8(a) and 9(a)). Fig. 4(b) also shows the state in which an overcap 90 that covers the nozzle head guide portion 17 and the nozzle head 70 is attached to the case cap 15. The overcap 90 is detachably attached to the case cap 15.

[0033] As described above, the discharge container body 20 includes the container body 30, the mounting cap 50, and the dispenser 60. In this embodiment, the container body 30 is detachable from the mounting cap 50 and configured as a replacement container that can be separated from the dispenser 60. In this embodiment, the container body 30 has a content storage space S (storage space) (see FIG. 5) that reduces in volume as the contents decrease. Each figure shows an example in which the container body 30 is configured as a flexible container (flexible bag) that reduces in volume as the contents decrease. By having the container body 30 have the content storage space S that reduces in volume as the contents decrease, it becomes easy to block air communication between the content storage space S and the outside. Therefore, the container body 30 can be suitably used as a container for storing contents that are undesirable when in contact with oxygen, such as hair dye liquid or various cosmetics.

[0034] In this embodiment, the container body 30 is configured as the above-mentioned flexible container, has a content-accommodating space S that shrinks and deforms as the content decreases, and is configured with an inner member 40 disposed in the mouth 31, as shown in Figure 5(a). The inner member 40 is a member that connects the internal space of the cylinder 62 of the dispenser 60 with the content-accommodating space S in the container body 30 via a suction tube 46, and is fitted into the mouth 31 of the container body 30. The configuration of the inner member 40 will be described below.

[0035] As shown in Figure 5(a), the inner member 40 comprises a cylinder accommodating cylindrical portion 41 that is inserted into the mouth portion 31 of the container body 30 and accommodates a cylinder 62 inside, a mouth fitting portion 42 that is provided on the outer surface of the cylinder accommodating cylindrical portion 41 and that fits the inner member 40 into the mouth portion 31 of the container body 30, a two-stage cylindrical communicating portion 43 that is connected to the lower end of the cylinder accommodating cylindrical portion 41 and that connects the content storage space S inside the container body 30 with the inside of the cylinder accommodating cylindrical portion 41, an outer fitting cylinder 44 that is fitted to the outside of the cylinder accommodating cylindrical portion 41, an inner fitting cylinder 45 that is fitted to the inside of the cylinder accommodating cylindrical portion 41, and a suction tube 46 that is connected to the lower end of the cylinder accommodating cylindrical portion 41.

[0036] The cylinder accommodating cylindrical portion 41 is configured in a cylindrical shape extending along the axial direction and includes an upper cylindrical portion 41a, a lower cylindrical portion 41b connected to the upper cylindrical portion 41a, and an annular bottom ring portion 41c protruding radially inward from the lower end edge of the lower cylindrical portion 41b. The lower cylindrical portion 41b of the cylinder accommodating cylindrical portion 41 is disposed within the mouth portion 31, and the upper cylindrical portion 41a protrudes above the mouth portion 31. A screw thread is provided on the outer peripheral surface of the upper cylindrical portion 41a, and engages with a screw groove on the mounting cap 50, allowing the mounting cap 50 to be detachably attached to the cylinder accommodating cylindrical portion 41.

[0037] The mouth fitting portion 42 is configured as a cap-shaped member fitted into the mouth 31 of the container body 30. Specifically, at the joint between the upper tubular portion 41a and the lower tubular portion 41b, it has a two-tiered annular top ring portion 42a that protrudes radially outward from the outer circumferential surface of the cylinder accommodating tubular portion 41, and a fitting tubular portion 42b that is connected to the outer edge of the top ring portion 42a. An axially extending groove 42c is formed on the inner surface of the fitting tubular portion 42b. An anti-rotation rib 32 that protrudes radially outward from the outer circumferential surface of the mouth 31 of the container body 30 is inserted into the groove, thereby fitting the inner member 40 into the container body 30 and preventing rotation.

[0038] Additionally, the upper part of the outer fitting tube 44, which is fitted onto the lower tube part 41b of the cylinder accommodating tube part 41, is fitted inside the top ring part 42a of the mouth fitting part 42. When the inner member 40 is fitted onto the mouth part 31 of the container body 30 by the mouth fitting part 42 as described above, the spaces between the upper end of the mouth part 31, the top ring part 42a of the mouth fitting part 42, and the outer fitting tube 44 are sealed via the packing 42d.

[0039] As described above, the communicating cylindrical portion 43 is provided at the lower end of the cylinder accommodating cylindrical portion 41. The communicating cylindrical portion 43 extends downward from the inner peripheral edge of the bottom ring portion 41c of the cylinder accommodating cylindrical portion 41, and has a two-stage cylindrical shape with a large diameter portion 43a located at the top and a small diameter portion 43b located at the bottom. The upper end of the suction pipe 46 is fitted inside the small diameter portion 43b.

[0040] The inner fitting cylinder 45 is fitted into the large diameter portion 43a of the communicating cylinder portion 43, and is also fitted onto the outer peripheral surface of a lower cylinder 62b of the cylinder 62, which will be described later.

[0041] In this embodiment, the container body 30 is configured as a replacement container that can be detached from the mounting cap 50 shown in FIG. 4(a) and other figures, as described above. Before the dispenser 60 is attached to the container body 30 via the mounting cap 50, a disk-shaped plug member 45a is provided on the inner circumferential surface of the inner fitting tube 45, as shown in FIG. 5(a). The outer circumferential edge of the plug member 45a is a breakable thin-walled portion. Therefore, the plug member 45a blocks communication between the content-accommodating space S in the container body 30 and the cylinder-accommodating tube portion 41 of the inner member 40.

[0042] Next, the mounting cap 50 and the dispenser 60 will be described. As shown in FIGS. 4(a) and 5(b), the mounting cap 50 is configured in a generally cylindrical shape with a top, and includes a side peripheral wall portion 51 and a cylinder holding portion 52 connected to the top end of the side peripheral wall portion 51. A stem insertion portion 53 is provided on the top surface of the cylinder holding portion 52, through which a stem 61 is inserted so as to be axially movable. As shown in FIG. 5(b), the upper end portion (fitting protrusion 62c) of the cylinder 62 is fitted inside the cylinder holding portion 52, thereby holding the dispenser 60 in the mounting cap 50. At this time, packings 52a are disposed between the cylinder holding portion 52 and the mouth portion 31 of the container body 30, and between the outer circumferential surface of the cylinder 62 and the mouth portion 31, thereby sealing these gaps.

[0043] Furthermore, the mounting cap 50 is provided with the flange portion 55 that projects radially outward from the outer circumferential surface of the side peripheral wall portion 51 .

[0044] As shown in Figure 5(b), the dispenser 60 is equipped with a cylinder 62, the stem 61 whose lower part is inserted into the cylinder 62 and which is arranged so as to be freely movable downward relative to the cylinder 62 while being biased upward in the axial direction, a piston which is linked to the up and down movement of the stem 61 and is fitted within the cylinder 62 so as to be freely slidable up and down, and a piston holder which is fitted within the cylinder 62 and supports the piston from above.

[0045] The cylinder 62 has a multi-stage cylindrical shape with the diameters of the stages decreasing axially downward. Specifically, the cylinder 62 includes an upper cylinder 62a with a larger diameter and a lower cylinder 62b with a smaller diameter, and the upper end edge of the upper cylinder 62a is provided with a fitting protrusion 62c that protrudes radially outward. The fitting protrusion 62c is fitted into the cylinder holding portion 52, thereby holding the cylinder 62 in the mounting cap 50. Furthermore, while held in the mounting cap 50, the cylinder 62 is housed in the cylinder housing cylindrical portion 41 (upper cylindrical portion 41a and lower cylindrical portion 41b) of the inner member 40. At this time, the lower cylinder 62b of the cylinder 62 is inserted into the communicating cylindrical portion 43 while fitted into the inner fitting cylinder 45.

[0046] As described above, before the dispenser 60 is attached, the plug member 45a is provided in the inner fitting cylinder 45. When the mounting cap 50 is attached while holding the dispenser 60, the cylinder 62 is inserted into the cylinder accommodating cylindrical portion 41, and the lower cylinder 62b of the cylinder 62 is inserted into the communicating cylindrical portion 43 and fitted into the inner fitting cylinder 45. During this time, the lower cylinder 62b of the cylinder 62 is pressed against the plug member 45a, causing the plug member 45a to break, and the content-accommodating space S in the container body 30 and the internal space of the cylinder 62 to communicate with each other via the suction tube 46 and the inner fitting cylinder 45.

[0047] Next, the nozzle head 70 will be described with reference to Figure 6. As shown in Figures 6(a) and (b), the nozzle head 70 comprises a nozzle portion 71 having the discharge port 71a, a mounting tubular portion 72 that fits with the stem 61 of each discharger 60 (60A, 60B), and connecting flow path portions 73 (73a, 73b) that connect the flow path in each mounting tubular portion 72 to the discharge port 71a. As shown in Figure 6(b), the interior of each mounting tubular portion 72 communicates with the stem 61 of each discharger 60, forming a flow path that faces upward in the axial direction.

[0048] The discharge port 71a is located above the nozzle head guide portion 17 provided on the case cap 15 of the accommodating case 10, and is located at a central position in the left-right direction of the accommodating case 10, as shown in Fig. 6(a). The discharge port 71a is located so as to protrude toward the outer peripheral wall portion 17a of the nozzle head guide portion 17, and the first connecting flow path portion 73a and the second connecting flow path portion 73b are generally arc-shaped when viewed from above.

[0049] Next, the flange receiving portion 80 will be described with reference to FIGS. 7 to 9. Here, FIG. 7(a) is a diagram showing a part of FIG. 4(b), and FIG. 7(b) is a top view of the flange receiving portion 80. Here, FIG. 7(b) (FIG. 4(b)) shows a state in which the flange receiving portion 80 is disposed at a position exactly midway between the first discharge container body 20A and the second discharge container body 20B. Also, FIGS. 8(a) to 8(c) are cross-sectional views as viewed axially upward from line DD in FIG. 1(b), showing only the case cap 15, the flange portion 55, and the flange receiving portion 80. Also, FIGS. 9(a) to 9(c) are cross-sectional views as viewed axially downward from line EE in FIG. 1(b), showing only the case cap 15, the flange receiving portion 80, and the support wall 12. In FIGS. 8 and 9, the positions where the discharge container bodies 20A and 20B are accommodated are indicated by dashed arrows.

[0050] As described above, the flange receiving portion 80 is disposed between the support wall 12 and the flange portion 55 in the axial direction as shown in FIG. 7(a), abuts against the upper end surface of the upper end portion 12a of the support wall 12, and is supported by the support wall 12. Also, as shown in FIGS. 8 and 9, the flange receiving portion 80 is provided rotatably between the first discharge container body 20A and the second discharge container body 20B around the rotation shaft portion 19. However, FIGS. 8(a) and 9(a) show a state in which the flange receiving portion 80 is disposed at a position exactly midway between the first discharge container body 20A and the second discharge container body 20B. FIGS. 8(b) and 9(b) show a state in which the flange receiving portion 80 is rotated toward the first discharge container body 20A, and FIGS. 8(c) and 9(c) show a state in which the flange receiving portion 80 is rotated toward the second discharge container body 20B.

[0051] As shown in FIGS. 7(a) and 7(b), the flange receiving portion 80 has a bearing 81, a bottom surface portion 82, and an outer peripheral frame portion 83 erected from the outer peripheral edge of the bottom surface portion 82. The bearing 81 is generally cylindrical and, as shown in FIG. 7(b), has a partially cut-out annular shape when viewed from above. The bottom surface portion 82 has an axisymmetric shape and is connected to the bottom end portion 81a of the bearing 81 as shown in FIG. 7(a). As shown in FIG. 7(a), the bottom surface portion 82 abuts against the upper end portion 12a of the support wall 12 and is supported from below in the axial direction by the support wall 12. Meanwhile, the upper end of the outer peripheral frame portion 83 is positioned at a height that allows it to abut against the lower surface of the flange portion 55.

[0052] Here, in the bottom surface portion 82 and outer peripheral frame portion 83 of the flange receiving portion 80, the area located on the first discharge container body 20A side of the symmetry axis As shown in Figure 7(b) is referred to as the first flange receiving area 80A, and the area located on the second discharge container body 20B side of the symmetry axis As is referred to as the second flange receiving area 80B.

[0053] 8(a) and 9(a), when the flange receiving portion 80 is disposed at an intermediate position between the first discharge container body 20A and the second discharge container body 20B, the first flange receiving area 80A of the flange receiving portion 80 abuts against the lower surface of the first flange portion 55A on the first discharge container body 20A side while abutting against the upper end portion 12a of the support wall 12. In addition, the second flange receiving area 80B abuts against the second flange portion 55B on the second discharge container body 20B side while abutting against the upper end portion 12a of the support wall 12.

[0054] When the flange receiving portion 80 is rotated toward the first discharge container body 20A, as shown in FIGS. 8(b) and 9(b), not only the first flange receiving area 80A but also the second flange receiving area 80B come into contact with the underside of the first flange portion 55A on the first discharge container body 20A side. At this time, the flange receiving portion 80 is retracted from the underside of the second flange portion 55B on the second discharge container body 20B side. Similarly, when the flange receiving portion 80 is rotated toward the second discharge container body 20B, as shown in FIGS. 8(c) and 9(c), not only the second flange receiving area 80B but also the first flange receiving area 80A come into contact with the second flange portion 55B on the second discharge container body 20B side. At this time, the flange receiving portion 80 is retracted from the underside of the second flange portion 55B on the first discharge container body 20A side.

[0055] In this way, the bottom surface portion 82 of the flange receiving portion 80 presents an axis of symmetry As passing through the rotation center of the bearing 81, and is shaped so that when positioned at an intermediate position between the first discharge container body 20A and the second discharge container body 20B, it abuts against the respective flange portions 55, when rotated toward the first discharge container body 20A it abuts only against the flange portion 55 on the first discharge container body 20A side, and when rotated toward the second discharge container body 20B it abuts only against the flange portion 55 on the second discharge container body 20B side.

[0056] As described above, the rotation shaft 19 is disposed on the front side of the accommodating case 10, and an opening 15b is provided on the rear side of the case cap 15 of the accommodating case 10 (see FIG. 7(a) and the like). The rear edge 83b of the outer peripheral frame 83 of the flange receiving portion 80 is positioned in the opening 15b, and the flange receiving portion 80 can be rotated to a desired position by moving the rear edge 83b with a finger or the like through the opening 15b toward the first discharge container body 20A or the second discharge container body 20B. At this time, the flange receiving portion 80 is configured so that the rotation of the flange receiving portion 80 can be temporarily restricted by a stopper (not shown) when the flange receiving portion 80 is positioned at one of three positions: a position rotated toward the first discharge container body 20A, an intermediate position between the first discharge container body 20A and the second discharge container body 20B, and a position rotated toward the second discharge container body 20B.

[0057] The operation of the duplex container 100 of this embodiment configured as described above will be described with reference to Fig. 10. Note that Fig. 10(a) corresponds to Fig. 1(b), Fig. 8(b), Fig. 9(b), etc., and shows a state in which the flange receiving portion 80 has been rotated toward the first discharge container body 20A. Also, some reference numerals have been omitted in Fig. 10.

[0058] In the double-barreled container 100 of this embodiment, when the nozzle head 70 is not pressed down, i.e., when no axial downward force is applied to the nozzle head 70, the first discharge container body 20A and the second discharge container body 20B are each positioned a predetermined distance axially above the bottom wall 11a of the case main body 11, and are held in a suspended state within the storage case 10.

[0059] 10(a), when the flange receiving portion 80 is rotated toward the first discharge container body 20A, as explained in FIGS. 8(b) and 9(b), the flange receiving portion 80 is retracted from the second flange portion 55B on the second discharge container body 20B side. When the nozzle head 70 is pressed axially downward in this state, the flange receiving portion 80 is disposed axially between the first flange portion 55A on the first discharge container body 20A side and the upper end portion 12a of the support wall 12, so that the first discharge container body 20A is fixed in the axial direction. Therefore, when the nozzle head 70 is pressed down, the stem 61 of the first dispenser 60A is pressed into the cylinder 62, and the first dispenser 60A is activated to dispense the content accommodated in the first container body 30A from the discharge port 71a.

[0060] On the other hand, since there is no flange receiving portion 80 below the flange portion 55 on the second discharge container body 20B side, when the nozzle head 70 is pressed axially downward as shown by the outlined arrow in Figure 10(b), the entire second discharge container body 20B moves axially downward within the storage case 10. At that time, since the stem 61 on the second dispenser 60B side is not pushed into the cylinder 62, the second dispenser 60B does not operate and the content stored in the second container body 30B is not dispensed from the discharge port 71a.

[0061] Then, when the downward axial force on the nozzle head 70 is released, the stem 61 is biased upward, so the stem 61 on the first discharge container body 20A side moves upward, and the nozzle head 70 moves upward in the axial direction. At that time, the stem 61 on the second discharge container body 20B side moves upward in the axial direction by the nozzle head 70, and accordingly the entire second discharge container body 20B moves upward in the axial direction, returning to the initial state shown in Fig. 10(a).

[0062] 10, when the flange receiving portion 80 is disposed at the intermediate position between the first discharge container body 20A and the second discharge container body 20B as shown in FIG. 8(a) and FIG. 9(a), the flange receiving portion 80 is disposed between the flange portions 55 (55A, 55B) of both the first discharge container body 20A and the second discharge container body 20B and the support wall 12 in the axial direction. In this case, both the first discharge container body 20A and the second discharge container body 20B are fixed in the axial direction. Therefore, when the nozzle head 70 is pressed down, the stems 61 of both dischargers 60 (60A, 60B) are pressed into the cylinders 62 in accordance with the pressing of the nozzle head 70, and both dischargers 60 (60A, 60B) are actuated, and the contents contained in both container bodies 30 (30A, 30B) are simultaneously discharged from the discharge ports 71a.

[0063] 8(c) and 9(c), when the flange receiving portion 80 is rotated toward the second discharge container body 20B, the second discharge container body 20B is fixed in the axial direction, and the first discharge container body 20A becomes movable in the axial direction. Therefore, when the nozzle head 70 is pressed down, only the second dispenser 60B is operated, and only the content accommodated in the second container body 30B is discharged from the discharge port 71a.

[0064] As described above, according to the duplex container 100 of the above embodiment, each discharge container body 20 is housed and held in the housing case 10 so as to be movable in the axial direction. By rotating the flange receiving portion 80, the user can select the discharge container body to be fixed in the axial direction. If different contents are housed in the first discharge container body 20A and the second discharge container body 20B, each content can be discharged individually or simultaneously. In this case, there is no need to provide a nozzle head 70 for each discharger 60 (60A, 60B) as in the conventional system. Instead, the nozzle head 70 can be used as a common component for both dischargers 60 (60A, 60B). Furthermore, since there is no need to provide a nozzle head 70 for each discharger 60 (60A, 60B), the nozzle head 70 portion can be configured compactly.

[0065] Furthermore, in the above embodiment, by rotating the flange receiving portion 80, it is possible to easily switch between discharging a plurality of contents individually or simultaneously.

[0066] Furthermore, in the above embodiment, the container body 30 is provided with an internal member 40 for communicating the internal space of the cylinder 62 of the dispenser 60 with the content storage space S of the container body 30, and the internal member 40 is provided with a suction tube 46 that communicates with the internal space of the cylinder 62. This configuration prevents the contents from adhering to the outer surface of the cylinder 62 when the mounting cap 50 is removed from the container body 30. Therefore, when replacing the container body 30 with a new one after using the contents, it is possible to prevent the contents adhering to the cylinder 62 from adhering to the hands, etc. Furthermore, because the suction tube 46 is also provided on the container body 30 side, the container body 30 can be replaced without touching the suction tube 46 with the contents adhering to it. Furthermore, when replacing the container body 30, the suction tube 46 is also replaced with a new one, so the contents do not come into contact with the used suction tube 46, keeping the contents clean.

[0067] The duplex container 100 described above is one aspect of the multiple container according to the present invention, and the multiple container according to the present invention is not limited to the duplex container 100 of the above embodiment, and can of course be modified as appropriate within the scope of the present invention. For example, in the duplex container 100 of the above embodiment, two discharge container bodies 20 are accommodated in the storage case 10, but three or more discharge container bodies 20 may be accommodated in the storage case 10 so as to be movable in the axial direction, and one or more of the multiple discharge container bodies 20 may be selected by operation by the user, etc., and the selected discharge container body 20 may be fixed in the axial direction, and when the nozzle head 70 is pressed down, only the dispenser 60 attached to the selected discharge container body 20 is activated, and the other discharge container bodies 20 are moved in the axial direction.

[0068] Furthermore, in the above embodiment of the double-barreled container 100, the dispenser 60 is attached to the mouth portion 31 of the container body 30 via the mounting cap 50, the mounting cap 50 is provided with a flange portion 55 that protrudes outward from its outer circumferential surface, the flange receiving portion 80 is arranged in the axial direction between the upper end portion 12a of the support wall 12 provided on the storage case 10 and the flange portion 55, and the flange receiving portion 80 is arranged to be rotatable between adjacent discharge container bodies 20, but the configuration for fixing the selected discharge container body 20 in the axial direction is not limited to this configuration.

[0069] For example, the support wall 12 may not stand upright on the bottom wall 11a of the case body 11, but may protrude from the inner surface of the case side peripheral wall 11b below the flange receiving portion 80. Furthermore, the form of the flange receiving portion 80 is not limited to the example described above, and a support member for supporting the flange portion 55 from the outside of the storage case 10 below the flange portion 55 may be provided as the flange receiving portion in an insertable and removable manner.

[0070] Furthermore, in the duplex container 100 of the above embodiment, the discharge container bodies 20 are accommodated and held within the storage case 10 so as to be axially movable, but for example, instead of the storage case 10, a holding holder that holds each discharge container body 20 so as to be axially movable may be configured. In this case, the holding holder may be configured so as to be able to be placed on a washbasin, shelf, etc., or may be attached to a wall, etc., as long as it is configured so as to be able to hold multiple discharge container bodies 20 so as to be movably in the direction in which the nozzle head 70 is pressed down.

[0071] Furthermore, in the above embodiment, the case cap 15 of the storage case 10 is provided with an opening 15b for rotating the flange receiver 80, but if the opening 15b is not provided and the flange receiver 80 is fixed at an intermediate position between the first dispensing container body 20A and the second dispensing container body 20B (FIGS. 7(a) and 8(a)), the duplex container 100 can also be configured to always dispense two types of contents simultaneously. In other words, by adopting the above configuration, the duplex container 100 can be used both as a container that dispenses two types of contents individually or simultaneously as needed, and as a container that always dispenses two types of contents simultaneously.

[0072] It is also possible to attach the dispenser 60 directly to the mouth 31 of the container body 30 via the mounting cap 50 without disposing the inner member 40 on the container body 30. In this case, the suction pipe 46 is attached to the suction end of the cylinder 62.

[0073] Furthermore, the form of the container body 30 in the multi-compartment container according to the present invention is not particularly limited, and in addition to the flexible container shown in the above embodiment, it may also be a container like an HVD (High Viscosity Dispenser) container used when dispensing highly viscous liquids such as lotions, which has an inner tray in the content storage space S, and the inner tray rises as the content decreases, thereby reducing the volume of the content storage space S.
