Summary of the Invention

Problems to be Solved by the Invention

[0004] As a discharge device for simultaneously discharging a first agent and a second agent or a discharge device for discharging a single agent, there is one that is detachably assembled to an aerosol container. Since the aerosol container has a structure in which the first agent and the second agent are discharged by pressing down a stem protruding from the top surface of the container, when attaching the discharge device to the aerosol container, the stem may be inadvertently pressed down and either or both of the first agent and the second agent may be accidentally discharged.

[0005] The present invention relates to a discharge container and a discharge device that can effectively suppress the discharge of an unintended agent when attached to an aerosol container. [Means for solving the problem]

[0006] This invention relates to a dispensing container comprising an aerosol container having a stem protruding from its top surface, and a dispensing device detachably attached to the top of the aerosol container. In one embodiment, it is preferable that the dispensing device comprises a cap, a nozzle extending in the height direction of the dispensing container and having a discharge port formed at its tip, a pressing member having a stem insertion cylinder portion attached to the stem of the aerosol container, and a dispensing operation unit for pushing the pressing member downward toward the stem. In one embodiment, it is preferable that the pressing member is interposed between the nozzle and the top surface, and that the flow path of the pressing member is connected to the flow path within the nozzle. In one embodiment, it is preferable that the dispensing operation unit has an operation body portion arranged around the aerosol container and a push-down portion arranged between the upper part of the cap and the pressing member. In one embodiment, it is preferable that the operating body portion has a support piece extending downward from the push-down portion and a pressing operating portion connected to the support piece. In one embodiment, it is preferable that the aerosol container or the connecting member attached to the aerosol container has a portion that faces the inner surface of the pressing operation portion. In one embodiment, it is preferable that the inner surface of the pressing operation part or the opposing part is provided with a sliding inclined portion that is inclined downward toward the aerosol container. In one embodiment, it is preferable that when the dispensing device is attached to the aerosol container, the cap restricts the downward movement of the stem insertion cylinder. In one embodiment, it is preferable that the dispensing container is configured such that when the pressing operation part is pushed toward the aerosol container, the pressing operation part slides downward along the sliding inclined part, and as a result, the operating body part also moves downward. [Effects of the Invention]

[0007] According to the dispensing container of this invention, when attached to an aerosol container, unintended dispensing of the agent can be effectively suppressed. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0009] Hereinafter, the ejection container of the present invention will be described based on its preferred embodiments with reference to the drawings. FIGS. 1 to 8 show an embodiment of the ejection container of the present invention. The description of the ejection device included in the ejection container described below can be appropriately applied to the ejection device of the present invention. The ejection container 1 of the present embodiment includes, as shown in FIGS. 1 to 3, a pair of aerosol containers 11, 11 having a stem 14 protruding from the top surface portion 13t, and an ejection device 10 detachably attached to the upper portion 13 of the aerosol container 11. The aerosol container 11 includes a vertically long container body 12 having a bottomed cylindrical shape for storing the content liquid, and the upper end opening of the container body 12 is closed by a mountain cup provided with the stem 14. This mountain cup forms the top surface portion 13t of the aerosol container 11, and when the stem 14 is pushed down, the valve mechanism provided in the mountain cup is opened, and the content liquid is ejected together with the propellant from the opening of the stem 14.

[0010] The ejection container 1 of the present embodiment is an ejection container for a two-component hair treatment agent composed of a first agent and a second agent. This hair treatment agent is used after mixing the first agent and the second agent immediately before use. The pair of aerosol containers 11, 11 are separately filled with the first agent and the second agent.

[0011] When the ejection container 1 of the present embodiment is in a self-standing state where the bottoms of the container bodies 12 of the pair of aerosol containers 11, 11 are grounded on a horizontal plane, the central axis direction of the container body 12 coincides with the vertical direction, and the ejection device 10 attached to the upper portion 13 of the aerosol container 11 is located above in the vertical direction. Hereinafter, unless otherwise specified, the description of the ejection container 1 of the embodiment shown in FIGS. 1 to 8 shall be the description of such a self-standing state.

[0012] In the discharging container 1, a pair of aerosol containers 11, 11 are arranged side by side such that the central axis directions of the container bodies 12 are parallel to each other as shown in FIGS. 1 and 2. The discharging container 1 of the present embodiment has a lateral direction X in which the pair of aerosol containers 11, 11 are arranged, a depth direction Y orthogonal to the lateral direction X, and a height direction Z orthogonal to each of the lateral direction X and the depth direction Y (see FIG. 2). The height direction Z coincides with the vertical direction.

[0013] The discharging container 1 of the present embodiment includes a connecting member 6 attached to the upper portions of the pair of aerosol containers 11, 11 (see FIGS. 1 and 2). The connecting member 6 connects the aerosol containers 11, 11 to each other in the lateral direction X and attaches the discharging device 10 to the upper portion 13 of the aerosol container 11. In the present embodiment, the pair of aerosol containers 11, 11 are maintained in a side-by-side state by the connecting member 6. The pair of aerosol containers 11, 11 may be integrally covered with a resin film such as a shrink film to reinforce the side-by-side state.

[0014] The connecting member 6 of the present embodiment has a top surface covering plate 63 disposed on the top surface portion 13t of the aerosol container 11 and a connecting cylindrical main body 60 disposed around the upper portion 13 of the aerosol container 11 (see FIG. 2). The top surface covering plate 63 is a substantially elliptical plate-shaped portion corresponding to the planar shape of the pair of side-by-side aerosol containers 11, 11, and is formed with a stem through-hole 63a through which the stem 14 is inserted and a plate insertion hole 63b through which an insertion plate 52 described later is inserted. The connecting cylindrical main body 60 is a cylindrical portion surrounding the top surface covering plate 63, and has an upper cylindrical portion 61 protruding upward from the peripheral edge of the top surface covering plate 63 and a lower cylindrical portion 62 protruding downward from the peripheral edge of the top surface covering plate 63. The outer surfaces of the upper cylindrical portion 61 and the lower cylindrical portion 62 are flush and continuous (see FIG. 1). The connecting member 6 forms a fitting recess that opens downward and is formed by the top surface covering plate 63 and the lower cylindrical portion 62, and the upper portion 13 of the pair of aerosol containers 11, 11 fits into the fitting recess. By inserting the upper portion 13 into the lower cylindrical portion 62, the connecting member 6 is attached to the pair of aerosol containers 11, 11.

[0015] The connecting member 6 of this embodiment has a pair of operation placement sections 65, 65 connected to each of the depth direction Y sides of the connecting cylindrical body 60 (see Figures 2 and 5). The operation placement section 65 is a wall portion with its main surface facing the depth direction Y, and hangs down from a part of the peripheral edge of the top surface covering plate 63. In a front view of the discharge container 1 viewed from one side in the depth direction Y (hereinafter also simply referred to as "front view"), the operation placement section 65 is located in the center of the lateral direction X so as to divide the connecting cylindrical body 60 into left and right lateral sections in the lateral direction X. In the mounted state in which the discharge device 10 is attached to the connecting member 6 (hereinafter also simply referred to as "mounted state"), the pressing operation section 32 of the operation body section 31, which will be described later, is arranged on the operation placement section 65. In this embodiment, the connecting member 6 has a portion facing the inner surface of the pressing operation portion 32 in the discharge container 1. The operation arrangement portion 65 corresponds to the facing portion. Instead of this connecting member 6, the aerosol container 11 may have an opposing portion.

[0016] As shown in Figure 2, the discharge device 10 comprises a cap 2, a nozzle 38 extending in the height direction Z and having a discharge port formed at its tip, a pressing member 5 that pushes down the stem 14, and a discharge operation unit 30 that pushes down the pressing member 5 toward the stem 14. The cap 2 has a cover body 20 that covers the pressing member 5 from above. In this embodiment, the cap 2 has a cylindrical nozzle cover portion 25 that covers the outer circumferential surface of the nozzle 38 and a cover body 20 that closes the upper opening of the connecting cylindrical body 60, with the nozzle cover portion 25 protruding upward from the cover body 20. In a plan view, the cover body 20 has an elliptical shape in which the long axis direction coincides with the horizontal direction X, and corresponds to the plan view shape of the top surface covering plate 63. The outer surfaces of the cover body 20 and the nozzle cover portion 25 are continuous and form a substantially inverted T shape in a front view (see Figure 1). These cover body 20 and nozzle cover portion 25 constitute the upper part 2S of the cap 2.

[0017] The cap 2 has a lower cap portion located below the cover body 20. In this embodiment, the cap 2 has a cylindrical wall portion 24 as its lower cap portion, which protrudes downward from the lower surface of the cover body 20 (see Figure 2). The cylindrical wall portion 24 has a missing portion in the center in the lateral direction X, and is divided into left and right halves in the lateral direction X by this missing portion. In a plan view, the cylindrical wall portion 24 has a shape that is smaller and approximately similar to the periphery of the cover body 20. In this embodiment, the cylindrical wall portion 24 has a cap-side restricting portion 29r formed along the depth direction Y (see Figure 6). This cylindrical wall portion 24 has cap-side restricting portions 29r at both ends in the lateral direction X, and the pressing-side restricting portion 53a, which will be described later, is inserted into the cap-side restricting portion 29r. In this embodiment, the cap-side restricting portion 29r consists of an opening that penetrates the cylindrical wall portion 24 (lower part of the cap). Alternatively, the cap-side restricting portion 29r may be a recessed portion formed in the cylindrical wall portion 24 (lower part of the cap). In this case, the cap-side restricting portion 29r will be a recessed portion with an opening on the side of the pressing-side restricting portion 53a, which will be described later.

[0018] The cap 2 of this embodiment has a cover step portion 23 as the lower part of the cap, which hangs down from a part of the edge of the cover body 20 along the lateral direction X. The cover step portion 23 protrudes outward in the depth direction Y from the outer surface of the cylindrical wall portion 24, and the length of the protrusion that extends downward from the cover body 20 is shorter than that of the cylindrical wall portion 24. The lower edge of the cover step portion 23 forms a step with the outer surface of the cylindrical wall portion 24 due to the thickness of the cover step portion 23, and corresponds to the shape of the upper edge of the connecting cylindrical body 60. When installed, the lower edge of the cover step portion 23 abuts against the upper edge of the connecting cylindrical body 60. In the dispensing device, it is preferable that the lower part of the cap has a cap-side contact portion that abuts against the aerosol container 11 or the connecting member 6 attached to the aerosol container 11. In this embodiment, the cap-side contact portion is the lower end of the cover step portion 23, and this lower end abuts against the upper edge of the upper cylindrical portion 61. Thus, the cap-side contact portion is composed of the part of the lower part of the cap that abuts against the aerosol container 11 or the connecting member 6, and consists of the lower end of the lower part of the cap, or parts such as ribs and plate-like portions provided on the lower part of the cap.

[0019] In this embodiment, the cap 2 is provided coaxially with the nozzle cover portion 25 and has a cylindrical nozzle insertion portion 26 that protrudes downward from the center of the inner surface of the cover body 20 (see Figures 5 and 6). The inside of the nozzle insertion portion 26 is in communication with the inside of the nozzle cover portion 25, and when installed, the nozzle 38 is inserted into the inside of the nozzle insertion portion 26 and the nozzle cover portion 25.

[0020] The discharge device 10 of this embodiment is equipped with a composite operation unit 3 in which the nozzle 38 and the discharge operation unit 30 are integrated (see Figure 2). The discharge operation unit 30 has a cylindrical push-down section 35 and a pair of operation body sections 31, 31 connected to the front and rear surface walls of the push-down section 35 along the lateral direction X. The push-down portion 35 of this embodiment has a roughly cross shape that is elongated in the lateral direction X when viewed from above, and has lateral ends that protrude outward in the lateral direction X from the front and rear surface walls that are aligned with the lateral direction X. The external dimensions of these lateral ends correspond to the internal dimensions of the outer frame wall portion 53, which will be described later, and fitting protrusions that fit with the inner surface of the outer frame wall portion 53 are formed on the outer surfaces of these lateral ends.

[0021] Each pair of operating body sections 31, 31 has a support piece 34 extending downward from the push-down section and a pressing operating section 32 connected to the support piece 34 (see Figure 2). More specifically, the operating body section 31 has a support piece 34 hanging down from the side wall of the push-down section 35 and a pressing operating section 32 connected to the lower end of the support piece 34. The pressing operation section 32 has an elliptical shape in which the long axis direction coincides with the height direction Z when viewed from the front, and a recess is formed on the outer surface that is recessed inward in the depth direction Y (see Figure 1). At the bottom of this recess, a plurality of ribs 32a extending in the lateral direction X are intermittently formed in the height direction Z.

[0022] In this embodiment, the inner surface of the pressing operation part 32, or the opposing part of the aerosol container 11 or the opposing part of the connecting member 6, is provided with a sliding inclined part that is inclined downward toward the aerosol container 11. The inner surface of the pressing operation section 32 of this embodiment is provided with a pull-down projection 33 that protrudes inward in the depth direction Y, and one edge 33a of the pull-down projection 33 forms a sliding inclined portion. More specifically, in a side view of the discharge container 1 viewed from one side in the lateral direction X (hereinafter also simply referred to as "side view"), the pull-down projection 33 has a triangular shape, and the upper edge (one edge) of the projection 33 is an inclined edge 33a that is inclined with respect to the inner surface of the pressing operation section 32 and the height direction Z [see Figures 7(a) and 8(a)]. In the installed state, the inclined edge 33a abuts against the lower end edge of the operation placement section 65. The sliding inclined section causes the operating body 31 to descend through the discharge operation described later.

[0023] The combined operating section 3 has an inner plate section 39 on which a nozzle 38 is erected (see Figure 2). The inner plate section 39 is continuous with the side wall of the push-down section 35 and is provided so as to span across the side walls in the depth direction Y. A through hole (not shown) is formed in the inner plate section 39, which is located coaxially with the central axis of the nozzle 38. The nozzle 38 protrudes upward from the inner plate section 39, beyond the upper edge of the push-down section 35. The nozzle 38 of this embodiment has a shape that tapers towards the tip. This nozzle 38 has a discharge tip portion 38a in which a discharge opening is formed, a base portion 38c that is continuous with the inner plate portion 39, and an intermediate portion 38b located between the discharge tip portion 38a and the base portion 38c (see Figure 4). The nozzle 38 has different inner diameters in the height direction Z, with the base portion 38c, intermediate portion 38b, and discharge tip portion 38a having larger inner diameters in that order. That is, the intermediate portion 38b has a larger inner diameter than the discharge tip portion 38a, and the base portion 38c has a larger inner diameter than the intermediate portion 38b. The inner dimensions of the base portion 38c correspond to the outer dimensions of the connecting channel forming portion 46, which will be described later, and a fitting projection is formed on the inner circumferential surface of the base portion 38c that fits onto the outer circumferential surface of the connecting channel forming portion 46.

[0024] The pressing member 5 of this embodiment has a pressing base plate 50 facing the top surface 13t of the aerosol container 11, an outer frame wall portion 53 rising upward from both ends in the depth direction Y on the periphery of the pressing base plate 50, and a lower flow path forming portion 54 protruding upward from the upper surface of the pressing base plate 50 (see Figure 2). The pressing member 5 also has an insertion plate 52 and a pair of stem insertion cylinder portions 56, 56 protruding downward from the lower surface of the pressing base plate 50 (see Figures 4 and 5). The pressing substrate 50 has a rectangular shape that is long in the lateral direction X, and the outer frame wall portion 53 rises from the edge along the depth direction Y of the pressing substrate 50 and from the edge of each corner (see Figure 5). The outer frame wall portion 53 is a wall portion that forms a frame on which the pressing portion 35 is placed on the pressing substrate 50, and has a U-shape in plan view (see Figure 2). On the inner surface of the wall portion of the outer frame wall portion 53 along the depth direction Y, fitting recesses are formed into which the lateral ends of the pressing portion 35 are fitted. Furthermore, in this embodiment, the outer frame wall portion 53 has a pressing-side restricting portion 53a formed in the portion along the depth direction Y (see Figures 4 and 6). This pressing-side restricting portion 53a consists of a protrusion that projects outward in the lateral direction X from the outer surface of the outer frame wall portion 53. Thus, the pressing-side restricting portion 53a is provided on the outer surface of the pressing member 5 (outer frame wall portion 53 in this embodiment).

[0025] The lower channel forming section 54 is located laterally inward (X) and inward in depth (Y) than the outer frame wall section 53. In plan view, the lower channel forming section 54 has a peripheral wall section 54a that is substantially elliptical in shape, and a pair of central partition walls 54b, 54b that divide the area enclosed by the peripheral wall section and extend in depth (Y) (see Figure 4). The outer circumferential surface of this peripheral wall section 54a has a fitting projection that fits with the peripheral wall section 44b of the lateral channel forming section 44, which will be described later. The internal space enclosed by the peripheral wall section 54a and the central partition walls 54b of the lower channel forming section 54 partially forms a channel for the liquid content (first agent or second agent) (see Figures 4 and 6).

[0026] The pair of stem insertion tubes 56, 56 are spaced apart in the lateral direction X, corresponding to the position of the stem 14. Each of the pair of stem insertion tubes 56, 56 is a cylindrical portion having a through hole into which the stem 14 is inserted. The through hole of the stem insertion tube 56 continuously penetrates the pressing substrate 50 (see Figures 4 and 6). This through hole is located within the region surrounded by the lower flow path forming portion 54 in a plan view. As a result, the inside of the stem insertion tube 56 communicates with the internal space (flow path) formed by the lower flow path forming portion 54 and the lateral flow path forming portion 44, which will be described later. The insertion plate 52 is located between a pair of stem insertion cylinders 56, 56 in the lateral direction X, and is a plate portion that hangs down from the lower surface of the pressing substrate 50 (see Figure 4).

[0027] The discharge device 10 of this embodiment comprises a composite inner member 4 which integrates a mixing member 43 and a lateral channel forming section 44 that partially forms a flow path for the liquid contents (first agent or second agent) (see Figure 2). The lateral channel forming section 44 has a top-cylindrical lateral channel forming section 44 and a cylindrical connecting channel forming section 46 that protrudes upward from the top surface 44a of the lateral channel forming section 44. The lateral channel forming section 44 has an elliptical top surface 44a and a peripheral wall 44b that protrudes downward from the periphery of the top surface. The internal dimensions of the peripheral wall 44b of the lateral channel forming section 44 correspond to the external dimensions of the peripheral wall 54a of the lower channel forming section 54. The connecting channel forming section 46 has a top surface on which the shaft 41 of the mixing member 43 is erected, and a pair of through holes 46a, 46a located on both sides of the top surface in the lateral direction X and penetrating in the height direction Z. The interiors of the pair of through holes 46a, 46a in the connecting channel forming section 46 are in communication with the interior of the lateral channel forming section 44 (see Figures 4 and 6).

[0028] The mixing member 43 has a shaft portion 41 extending in the height direction Z and a screw blade 42 helically attached around the shaft portion 41. When installed, the mixing member 43 is positioned in the flow path inside the nozzle 38. This mixing member 43 is a static mixer, and by passing the first agent and the second agent (content liquid) through the flow path provided inside the static mixer, the contents can be mixed without the need for a motor or other drive. Instead of the configuration with a shaft portion 41 and screw blade 42 shown in Figure 4, the mixing member 43 may be a static mixer in which a helical screw (screw groove) is formed on the outer surface of a round rod-shaped shaft to form a helical flow path.

[0029] The composite inner member 4 has an extended fitting portion 47 that extends outward in the depth direction Y from the portion of the peripheral wall of the lateral flow path forming portion 44 along the lateral direction X, and fits onto the pressing substrate 50. A recess corresponding to the thickness of the pressing substrate 50 is formed on the inner surface of the extended fitting portion 47, and the composite inner member 4 can be fixed to the pressing member 5 by fitting the pressing substrate 50 into the recess.

[0030] The discharge device 10 of this embodiment is constructed by assembling a cap 2, a composite operating section 3, a composite inner member 4, and a pressing member 5. In this embodiment, first, the composite inner member 4 and the pressing member 5 are assembled. Specifically, the composite inner member 4 is placed on the upper surface of the pressing base plate 50 of the pressing member 5, and the composite inner member 4 is fixed to the pressing base plate 50 by the extended fitting portion 47. At the same time, the inner surface of the peripheral wall portion of the lateral flow path forming section 44 is placed on the outer surface side of the peripheral wall portion 54a of the lower flow path forming section 54, and the peripheral wall portions 54a and 44b of these flow path forming sections 54, 44 are fitted together. This creates an internal space defined by the peripheral wall portion 54a and the central partition wall 54b of the lower flow path forming section 54, and the top surface portion 44a and the peripheral wall portion 44b of the lateral flow path forming section 44 (see Figure 4). This internal space communicates with the through-hole of the stem insertion tube 56 and serves as a flow path for the liquid inside.

[0031] The pressing member 5 and the composite inner member 4 are assembled to the composite operating unit 3. Specifically, the mixing member 43 is inserted into the nozzle 38, and the connecting channel forming part 46 is inserted into the base end portion 38c of the nozzle 38, so that the connecting channel forming part 46 is fitted into the base end portion 38c. As a result, the mixing member 43 is positioned in the intermediate portion 38b (inside the channel) which is continuous with the discharge tip portion 38a, and the inside of the pair of through holes 46a in the connecting channel forming part 46 is in communication with the inside of the nozzle 38 (see Figure 4). In addition, the lateral ends of the push-down portion 35 are positioned on the inner surface side of the outer frame wall portion 53 of the pressing member 5, and the outer frame wall portion 53 and the lateral ends of the push-down portion 35 are fitted together. In this fitted state, the lower ends of both lateral ends of the pressing portion 35 are positioned on the pressing substrate 50, and the inner plate portion 39 is positioned on the top surface portion 44a of the lateral flow path forming portion 44. The pressing portion 35 is also positioned to surround the periphery of the lateral flow path forming portion 44.

[0032] The composite operating section 3, to which the pressing member 5 and the composite inner member 4 are assembled, is assembled to the cap 2. Specifically, the nozzle 38 is inserted into the nozzle insertion section 26 and the nozzle cover section 25, and the outer frame wall section 53 is positioned in the internal space of the cap 2 defined by the cover body 20 and the cylindrical wall section 24 (see Figures 3 and 5). The pressing side regulating section 53a of the outer frame wall section 53 is engaged with the cap side regulating section 29r of the cylindrical wall section 24 (see Figure 6). More specifically, the pressing side regulating section 53a, which is a convex portion, is inserted into the cap side regulating section 29r, which is an opening. Since the length of the cap side regulating section 29r (opening) is longer in the height direction Z than the length of the pressing side regulating section 53a (convex portion), the pressing side regulating section 53a can move in the height direction Z within the cap side regulating section 29r (see Figure 6). As a result, the outer frame wall section 53 can move relative to the cylindrical wall section 24 in the height direction Z. In other words, in the discharge device 10, the pressing member 5 is assembled to be movable relative to the cap 2 in the height direction Z. The cap-side restricting portion 29r and the pressing-side restricting portion 53a restrict the amount of movement (downward movement) of the pressing member 5 relative to the cap 2. Such assembly is performed by a convex portion (pressing-side restricting portion 53a) and a concave portion or opening (cap-side restricting portion 29r) formed on the outer surface of the outer frame wall portion 53 and the inner surface of the cylindrical wall portion 24. By assembling the cap 2, composite operating portion 3, composite inner member 4, and pressing member 5 in this manner, the discharge device 10 is obtained. In the discharge device 10 of this embodiment, the discharge tip portion 38a of the nozzle 38 protrudes upward from the upper opening of the nozzle cover portion 25 (see Figures 1 and 3).

[0033] In the dispensing device 10, the pressing member 5 is interposed between the nozzle 38 and the top surface 13t of the aerosol container 11 (see Figures 3 and 4). In the dispensing device 10, the flow paths formed by the lower flow path forming section 54 and the lateral flow path forming section 44 are connected to the flow paths inside the nozzle 38 via the through holes 46a, 46a of the connecting flow path forming section 46 (see Figure 4). More specifically, the through hole of the stem insertion cylinder section 56, the internal space formed by the lower flow path forming section 54 and the lateral flow path forming section 44, the through holes 46a, 46a of the connecting flow path forming section 46, and the inside of the nozzle 38 (intermediate section 38b) are in communication, forming a flow path for the liquid contents. This flow path for the liquid contents is connected to each of the stems 14 of the pair of aerosol containers 11 and merges inside the intermediate section 38b (see Figure 4). In other words, the first and second agents discharged from the stem 14 pass through independent channels up to the intermediate section 38b, where they are mixed by the mixing member 43. From the viewpoint of better mixing of the first and second agents, it is preferable that the shaft portion 41 of the mixing member 43 extends from the intermediate portion 38b to the discharge tip portion 38a.

[0034] In the discharge device 10, a pair of operating body parts 31, 31 protrude outward in the depth direction Y from a missing portion in the cylindrical wall portion 24 of the cap 2 (see Figures 5 and 7(a)). The operating body part 31 has at least the upper end of the support piece 34 covered by the lower part of the cap (in this embodiment, the cover step portion 23 and the cylindrical wall portion 24), while the pressing operating part 32 is exposed from the lower edge of the lower part of the cap (see Figure 1). As a result, when attaching the discharge device to the connecting member 6, the downward pressing of the support piece 34 can be suppressed by the lower part of the cap, thereby preventing unintended discharge.

[0035] The discharge device 10 has a cylindrical wall portion 24 positioned inside the upper cylindrical portion 61 so as to close the upper opening of the upper cylindrical portion 61 of the connecting member 6 (see Figure 5), and is attached to the connecting member 6 by fitting the cap 2 and the connecting member 6 together. Such fitting is achieved by the convex and concave portions formed on the outer surface of the cylindrical wall portion 24 and the inner surface of the upper cylindrical portion 61. In the installed state, i.e., in the discharge container 1, the lower edge of the cover step portion 23 abuts against the upper edge of the upper cylindrical portion 61 (connecting cylindrical body 60), the pressing member 5 is positioned inside the upper cylindrical portion 61, and the operating body portions 31, 31 are positioned on the outer surface side of the operating arrangement portions 65, 65. The operating arrangement portion 65 faces the inner surface of the pressing operating portion 32. The insertion plate 52 is inserted into the gap between the upper parts 13 of the pair of aerosol containers 11, 11.

[0036] In the discharge container 1, the operating body 31 is arranged around the pair of aerosol containers 11, 11, the lower part of the pressing operating part 32 is located below the operating arrangement part 65, and the inclined edge 33a (sliding inclined part) of the pull-down projection 33 faces the lower end of the operating arrangement part 65 [see Figure 7(a)]. In the discharge container 1, the push-down portion 35 is positioned between the upper part 2S of the cap 2 and the pressing member 5. In this embodiment, the push-down portion 35 is positioned inside the cap 2 and above the pressing member 5 (on the opposite side from the stem 14). More specifically, the push-down portion 35 is sandwiched between the cover body 20 and the pressing substrate 50 (see Figure 3). A stem insertion cylinder portion 56 is positioned below the pressing substrate 50. Before the discharge operation, the stem insertion cylinder portion 56 is at a height that does not press down the stem 14 (see Figure 7(b)).

[0037] In this embodiment, the dispensing container 1 can dispense its contents from the nozzle 38 by performing a dispensing operation on the operating body 31. The dispensing operation in this embodiment involves pressing the pressing operation parts 32 of each of the pair of operating body parts 31, 31 with a finger, pushing the pressing operation parts 32, 32 inward in the depth direction Y (i.e., toward the aerosol container 11) [see Figure 8(a)]. When the pressing operation parts 32 of both operating body parts 31, 31 are pressed simultaneously, the inclined edge 33a comes into contact with the lower end of the operating position part 65, and the downward projection 33 slides along the inclined edge 33a, causing the pressing operation parts 32 to slide downward [see Figure 8(a)]. As this sliding downward occurs, the operating body 31 descends, and together with the downward pressing part 35 to which the support piece 34 is attached, the pressing base plate 50 is pushed down, and the stem insertion cylinder part 56 on the lower side of the pressing base plate 50 is also pushed down [see Figure 8(b)]. As a result, the stem 14 is pushed down, and the liquid contents (first agent and second agent) are discharged from the opening of the stem 14. In this way, the discharge device 10 of this embodiment, as a result of the discharge operation described above, causes the operating body 31, the push-down part 35, and the pressing member 5 to descend relative to the cap 2. The first and second agents discharged from the stem 14 pass through the aforementioned flow path, are mixed by the mixing member 43 in the intermediate section 38b, reach the discharge port of the discharge tip 38a, and are discharged from the discharge port as a mixture of the first and second agents.

[0038] During the discharge operation on the operating body 31 described above, in the discharge container 1 of this embodiment, the stem insertion cylinder 56 is pushed down in conjunction with the push-down section 35, and the relative movement of the pressing member 5 with respect to the cap 2 in the height direction Z is restricted by the contact between the pressing-side restricting section 53a and the cap-side restricting section 29r (see Figure 6). In other words, the pressing-side restricting section 53a and the cap-side restricting section 29r act as a downward stopper for the pressing member 5. In the discharge container 1 of this embodiment, during the discharge operation, the pressing member 5 can descend relative to the cap 2 until the pressing-side restricting section 53a contacts the cap-side restricting section 29r. As a result, even if the operating body 31 descends excessively, the pressing member 5 is less likely to follow the descent, effectively suppressing damage to the stem 14, and stabilizing the amount of liquid ejected (ejection speed) by maintaining the amount of downward movement of the pressing member 5 within a predetermined range.

[0039] In this embodiment, the discharge container 1 can stop discharging the contents by stopping the discharge operation on the operating body 31. That is, the discharge of the contents can be stopped by releasing the pressure on the pressing operation part 32. When the pressure on the pressing operation part 32 is released, the pull-down projection 33 rises relative to the lower end of the operating arrangement part 65, and the operating body 31 (pressing operation part 32 and support piece 34) returns to its original height position before the discharge operation [see Figure 7(a)]. Accordingly, the push-down part 35 also returns to its original height position, and the pressing base plate 50 also returns to its original height position [see Figure 7(b)]. As a result, the push-down of the stem 14 by the stem insertion cylinder part 56 is released, and the discharge of the contents (first agent and second agent) is stopped.

[0040] The dispensing device 10 is designed so that when it is attached to a pair of aerosol containers 11, 11, the cap 2 restricts the downward movement of the stem insertion cylinder portion 56. In this embodiment, when the dispensing device 10 is attached to the connecting member 6, the lower edge of the cover step portion 23 abuts against the upper edge of the upper cylinder portion 61 (connecting cylindrical body 60), thereby restricting further downward movement of the cap 2. In other words, the lower edge of the cover step portion 23 of the cap 2 acts as a downward stopper for the cap 2, and can also restrict the downward movement of the composite operating portion 3 assembled to the cap 2, and the downward movement of the pressing member 5 assembled to the composite operating portion 3. As a result, even if the cap 2 is excessively pressed against the connecting member 6 when the dispensing device 10 is attached, the downward movement portion 35 and the pressing member 5 will not move, effectively suppressing unintended discharge of the liquid contents.

[0041] When the dispensing device 10 is attached to a pair of aerosol containers 11, 11, a portion of the cap 2 comes into contact with the aerosol container 11 or a member attached to the aerosol container 11 (for example, a connecting member 6) in the height direction Z. In this embodiment, the dispensing device 10 has a cover step portion 23 that comes into contact with the connecting cylindrical body 60, but other parts of the cap 2, such as the cover body 20 or the cylindrical wall portion 24, may come into contact with the aerosol container 11 or the connecting member 6 and function as a downward stopper. It is preferable that the movement of the pressing member 5 in the height direction Z is restricted in this manner. Furthermore, when a portion of the cap 2 comes into contact with the aerosol container 11 during attachment, it is preferable that the portion of the cap 2 comes into contact with a portion other than the stem 14, such as the peripheral edge of the top surface 13t of the aerosol container 11. Furthermore, when the cap-side contact portion contacts the connecting member 6 and restricts the downward movement of the cap 2, it is preferable that the cap-side contact portion contacts an upward-facing portion of the connecting member 6 (for example, the upper surface of the top covering plate 63 or the upper edge of the upper cylindrical portion 61).

[0042] From the viewpoint of further suppressing unintended discharge of liquid contents, it is preferable that in the discharge container 1, the amount of movement of the cap 2 in the height direction Z is smaller than the amount of movement of the pressing member 5 in the height direction Z. This configuration also includes the case where the amount of movement of the cap 2 is 0, that is, when the position of the cap 2 in the height direction Z (height position) in the discharge device 10 is fixed. The amount of movement of the cap 2 is the distance (clearance) between the cap-side contact portion in the height direction Z and the part that the cap-side contact portion contacts (aerosol container 11 or part of the connecting member 6). The amount of movement of the pressing member 5 is the distance (clearance) between the cap-side restricting portion 29r and the pressing-side restricting portion 53a in the height direction Z, and corresponds to the relative amount of movement (downward movement) of the pressing member 5 with respect to the cap 2 as described above. In other words, the amount of movement is restricted by the cap-side restricting portion 29r and the pressing-side restricting portion 53a. From the same viewpoint as described above, the difference between the amount of movement of the cap 2 in the height direction Z of the discharge container 1 and the amount of movement of the pressing member 5 in the height direction Z is preferably 0.1 mm or more and 10 mm or less, more preferably 0.1 mm or more and 2 mm or less. The amount of movement of the pressing member 5 in the height direction Z corresponds to the height difference D1 (see Figure 6) between the cap-side restricting portion 29r and the pressing-side restricting portion 53a, and can be the amount of movement (change) of the lower end of the stem insertion cylinder portion 56 in the height direction Z before and after the discharge operation.

[0043] From the viewpoint of further suppressing unintended discharge of the liquid contents, it is preferable that the height position (position in the height direction Z) of the cap 2 in the discharge container 1 is fixed by the connecting cylindrical body 60. In this embodiment, the cap 2 is able to fit the cylindrical wall portion 24 and the upper cylindrical portion 61 together by convex and concave portions (not shown) formed on the outer surface of the cylindrical wall portion 24 and the inner surface of the upper cylindrical portion 61, and the height position of the cap 2 is fixed by this fitting and the stopper.

[0044] From the viewpoint of further suppressing unintended discharge of the liquid contents during attachment, it is preferable that the cap 2 and the operating body 31 are separate components. In this way, when the cap 2 and the component that contributes to pressing down the pressing member 5 (operating body 31) are independent components, the height position of the cap 2 is less likely to change before and after the discharge operation. In this embodiment, the dispensing device 10 has a cap 2 and a nozzle 38 as separate components, and a composite operating unit 3 in which the nozzle 38 and the operating body 31 are integrated. Examples of the integrated form of the nozzle 38 and the operating body 31 include those in which the nozzle 38 and the operating body 31 are joined by adhesive, welding, or fitting. When the aforementioned dispensing operation is performed on the operating body 31 of this dispensing device 10, the nozzle 38 is pushed down together with the push-down part 35 [see Figure 8(b)]. This configuration is preferable because the nozzle 38 and the pressing member 5 can be moved integrally in the height direction Z, thereby improving the sealing performance of the flow path of the liquid contents. In this embodiment, the nozzle 38 and the operating body 31 are integrally molded. This configuration is more preferable in that it can further improve the sealing performance of the flow path of the liquid contents.

[0045] In this embodiment, the nozzle 38 has a central axis direction that coincides with the height direction Z, and the discharge tip 38a has a tapered shape that narrows in diameter towards the tip. This makes it easy to position the discharge port of the nozzle 38 at the roots and partings of the hair, and facilitates the operation of supplying the mixed solution of the first and second agents to the roots and partings of the hair. The central axis of the nozzle 38 may be inclined with respect to the height direction Z (vertical direction). In this case, the angle between the central axis of the nozzle 38 and the height direction Z is preferably 70° or less, more preferably 45° or less.

[0046] In this embodiment, the operating section 65 is an opposing section of the connecting member 6 that faces the inner surface of the pressing operating section 32. Preferably, a pair of guide protrusions 66, 66 extending in the height direction Z are formed near the opposing section of the aerosol container 11 or the opposing section of the connecting member 6 (in this embodiment, the operating section 65) (see Figures 1 and 5). In this embodiment, the operating section 65 has a pair of guide protrusions 66, 66 on both side edges that extend in the height direction Z. This pair of guide protrusions 66, 66 are protrusions that project from the outer surface of the opposing section and are arranged along both side edges of the support piece 34 in the dispensing device. In other words, the support piece 34 is sandwiched between the pair of guide protrusions 66, 66. When the support piece 34 comes into contact with the guide projection 66, the movement of the support piece 34 in the circumferential direction (lateral direction X in this embodiment) of the dispensing device is restricted. This stabilizes the dispensing operation, improves the user experience, and makes it easier to maintain uniformity in the amount of liquid dispensed.

[0047] The discharge device 10 and connecting member 6 of this embodiment are molded products made of synthetic resin. As the synthetic resin, various known materials such as polyolefins such as polypropylene and polyethylene, polyesters such as polyethylene terephthalate, and polyamides such as nylon can be used.

[0048] Furthermore, from the viewpoint of easily confirming the discharge of the first and second agents, it is preferable that the cap 2 and the composite inner member 4 each have at least a portion of a transparent part that allows the inside to be seen. In this case, it is more preferable that the top surface portion 44a of the cover body 20 and the lateral flow path forming portion 44 each have a transparent part. Such a configuration is effective in that the inside of the flow path of the liquid contents can be seen through the transparent part. The transparent part is a portion made of transparent or translucent resin.

[0049] Next, another embodiment of the discharge container according to the present invention will be described. In the following, the components of the other embodiment will be described mainly in terms of components that differ from those of the embodiments shown in Figures 1 to 9, and similar components will be denoted by the same reference numerals and their description will be omitted. For components that are not specifically described, the description of the embodiments shown in Figures 1 to 9 will be applied as appropriate.

[0050] In the above-described embodiment, the discharge container 1 (discharge device 10) had the discharge tip 38a of the nozzle 38 protruding upward from the upper opening of the nozzle cover portion 25, but it is not limited to this configuration. For example, as shown in Figure 9, the discharge container 1a may have the tip of the nozzle 38 housed inside the nozzle cover portion 25.

[0051] In the above-described embodiment, the discharge container 1 (discharge device 10) had a cap 2 with a cylindrical wall portion 24 disposed within the upper cylindrical portion 61. However, instead of the cylindrical wall portion 24, the cap 2 may have a cover outer wall portion 24r disposed around the connecting member 6, including the upper cylindrical portion 61. In other words, the cap 2 may be an overcap that covers the connecting member 6. The cover outer wall portion 24r is a peripheral wall portion that hangs down from the periphery of the cover body 20 and protrudes downward to or beyond the lower end of the connecting member 6. When installed, the cover outer wall portion 24r covers the outer surface of the connecting member 6. In this case, the connecting member 6 is housed within the cylindrical cover outer wall portion 24r.

[0052] The cap 2b in the embodiment shown in Figures 10 to 15 has a cover outer wall portion 24r as the lower part of the cap. The inner circumferential surface of the lower end of this cover outer wall portion 24r has an elliptical shape similar to the outer circumferential surface of the connecting member 6 in a plan view, and the connecting member 6 can be inserted through the lower end opening of the cover outer wall portion 24r.

[0053] In this embodiment, the outer wall portion 24r of the cover has a cutout portion 24d that curves upward convexly at the lower end of the central part in the lateral direction X when viewed from the front, and the pressing operation portion 32 is positioned below the cutout portion 24d (see Figure 10). In the discharge container 1b of this embodiment, the upper half or more of the support piece 34 is covered by the cap 2b, more specifically by the outer wall portion 24r of the cover, while the pressing operation portion 32 connected to the support piece 34 is exposed from the lower edge of the outer wall portion 24r (below the cap). In this manner, the outer wall portion 24r of the cover (lower part of the cap) preferably covers more than the upper half of the total length of the support piece 34 in the height direction Z, and more preferably covers the entire length of the support piece 34. With this configuration, unintended pressing down of the support piece 34 during the assembly of the dispensing device 10 can be further suppressed, and the intuitive assembly of the dispensing device 10 can be facilitated.

[0054] In the discharge container 1b (discharge device 10) of this embodiment, the inner surface of the outer wall portion 24r of the cover faces the outer circumferential surfaces of the upper cylindrical portion 61 and the lower cylindrical portion 62 of the connecting member 6 (see Figure 11). Furthermore, in this embodiment, the lower end 25b of the nozzle cover portion 25 of the cap 2b extends downward from the cover body 20, and this extended portion is located inside the cap 2b.

[0055] In this embodiment, the lower end of the outer wall portion 24r of the cover of the dispensing container 1b is positioned above the mountain cup of the aerosol container 11 and above the upper end of the container body 12 in the height direction Z (see Figures 10 and 11). With this configuration, the lower end of the outer wall portion 24r of the cover can approach or come into contact with the outer surface of the container body 12, so that the posture of the combined operating section 3 can be stably maintained. More specifically, even if one-handed operation is performed by pressing only one of the pressing operating sections 32 during dispensing, the bias of the combined operating section 3 to one side in the depth direction Y can be effectively suppressed, and dispensing operability and dispensing stability can be further improved.

[0056] In this embodiment, a guide projection 27 extending in the height direction Z is formed on the inner surface of the cover outer wall portion 24r (see Figures 12 and 14). This cover outer wall portion 24r has a pair of guide projections 27, 27 located laterally outward in the lateral direction X than the nozzle cover portion 25. The guide projections 27 in this embodiment are projections that protrude inward in the depth direction Y from the inner surface of the cover outer wall portion 24r and are continuous with the entire length of the cover outer wall portion 24r in the height direction Z. That is, the pair of guide projections 27, 27 reach the lower edge of the cover outer wall portion 24r. The pair of guide projections 27, 27 are arranged so as to sandwich the missing portion 24d of the cover outer wall portion 24r in the lateral direction X.

[0057] In the dispensing device 10, the guide protrusions 27 are arranged along both side edges of the support piece 34. That is, in the lateral direction X, the pair of guide protrusions 27, 27 are arranged to sandwich the support piece 34. As a result, in the dispensing container 1b of this embodiment, the support piece 34 contacts the guide protrusions 27, thereby restricting the movement of the support piece 34 in the circumferential direction (lateral direction X in this embodiment) of the dispensing device. More specifically, when the pressing operation part 32 is pressed, the lateral (left and right) wobble of the support piece 34 can be suppressed, and the pressing member 5 can be pressed down in a balanced manner. This effect is desirable because it allows for both uniform dispensing and ease of operation, even when operated with one hand as described above. That is, even with one-handed operation, the first and second agents can be dispensed more uniformly, thus stabilizing the mixing of these two agents and improving the user experience of the dispensing container 1b.

[0058] In the embodiments shown in Figures 1 to 8 above, the discharge container 1 is prevented from descending further by the contact between the cover step portion 23 and the upper end edge of the upper cylindrical portion 61. However, this restriction may also be achieved by the contact between the cover outer wall portion 24r and the connecting member 6. In the embodiments shown in Figures 10 to 15, the downward movement of the cap 2 is restricted when the cap-side contact portion, which consists of a recess or protrusion provided on the inner surface of the outer wall portion 24r of the cover, comes into contact with each part of the connecting member 6b or the connecting cylindrical body 60, which consists of a connecting-side contact portion 68 provided on the outer surface of the connecting cylindrical body 60.

[0059] The outer wall portion 24r of the cover in this embodiment has a cap-side contact portion consisting of a protrusion formed on the inner surface of the front and rear surface walls along the lateral direction X. The aforementioned pair of guide protrusions 27, 27 have a semi-elliptical portion 27a at their upper end that protrudes most inward in the depth direction Y (see Figures 14 and 15), and this portion forms the contact portion on the cap side. In the discharge device of this embodiment, the lower end of the semi-elliptical portion 27a of the guide protrusion 27 is positioned on the top surface covering plate 63 of the connecting member 6 (see Figures 14 and 15). The lower end of this semi-elliptical portion 27a contacts the top surface covering plate 63, thereby restricting the downward movement of the cap 2.

[0060] Furthermore, the outer wall portion 24r of the cover in this embodiment has a pair of cap-side contact portions 28b (hereinafter also referred to as "vertical cap-side contact portions 28b") which are located laterally outward in the X direction from the pair of guide protrusions 27, 27 and extend in the height direction Z (see Figures 14 and 15). These vertical cap-side contact portions 28b consist of protrusions that project inward in the depth direction Y from the inner surface of the outer wall portion 24r, and have a semi-elliptical portion that protrudes the most inward in the depth direction Y at its upper end. In these vertical cap-side contact portions 28b, the lower end of the semi-elliptical portion is located above the lower ends of the guide protrusions 27, 27. In the discharge device, the lower end of the semi-elliptical portion of the vertical cap contact portion 28b is positioned on the upper edge of the upper cylindrical portion 61 (see Figures 14 and 15). The lowering of the cap 2 is restricted when this semi-elliptical portion comes into contact with the upper cylindrical portion 61.

[0061] The outer wall portion 24r of the cover in this embodiment has a cap-side contact portion 28c (hereinafter also referred to as the "lower cap-side contact portion 28c") on its inner surface along the depth direction Y, which consists of a recess extending in the depth direction Y (see Figures 14 and 15). The connecting member 6 in this embodiment also has a connecting-side contact portion 68 (hereinafter also referred to as the "lower connecting-side contact portion 68") on the outer surface of the lower cylindrical portion 62 along the depth direction Y, which consists of a convex portion that protrudes outward in the lateral direction X and extends in the depth direction Y (see Figures 14 and 15). These lower cap-side contact portion 28c and lower connecting-side contact portion 68 engage with each other in the discharge device. That is, the lower cap-side contact portion 28c and the lower connecting-side contact portion 68 come into contact with each other, thereby restricting the downward movement of the cap 2.

[0062] The cap 2b of this embodiment has a pair of internal cap beams 29, 29 inside (see Figures 14 and 15). The internal cap beams 29 of this embodiment are parts that connect the inner surfaces of the outer cover wall 24r. More specifically, the internal cap beams 29 are plate-like portions that hang down from the inner surface of the cover body 20 and have thickness in the lateral direction X, and are arranged to span between the front and rear wall portions of the outer cover wall 24r along the lateral direction X. The internal cap beams 29 are located outward in the lateral direction X from the vertical cap side contact portion 28b. In this embodiment, the internal beam portion 29 of the cap has an opening formed at its lower end that penetrates the plate-like portion. This opening corresponds to the aforementioned cap-side restricting portion 29r. In the discharge device, the internal beam portion 29 of the cap has a lower end edge that extends in the depth direction Y, and the portion of the lower end edge that is outward in the depth direction Y abuts against the upper end edge of the upper cylindrical portion 61 (see Figures 13 and 15). In other words, the internal beam portion 29 of the cap in this embodiment functions as a cap-side contact portion.

[0063] In this embodiment, the pressing member 5 has a protrusion 53a formed on the outer surface of the outer frame wall portion 53 along the depth direction Y, which protrudes outward in the lateral direction X and extends in the depth direction Y (see Figure 11). This protrusion 53a corresponds to the pressing side restricting portion 53a. In the discharge device of this embodiment, the pressing member 5 is housed within the outer wall portion 24r of the cover together with the connecting member 6b, and the outer frame wall portion 53 is sandwiched between a pair of inner beam portions 29, 29 of the cap in the lateral direction X (see Figure 13). In this state, the protrusion forming the pressing-side restricting portion 53a is positioned within the opening forming the cap-side restricting portion 29r (see Figures 11 and 13). In this way, the composite operating portion 3 with the pressing member 5 assembled is attached to the cap 2b. In this embodiment as well, in the height direction Z, the relative movement amount of the pressing member 5 with respect to the cap 2 is restricted by the contact between the pressing-side restricting portion 53a and the cap-side restricting portion 29r. For ease of explanation, the composite inner member 4 is omitted from the illustration in Figures 12 to 15.

[0064] This invention is not limited to the embodiments described above and can be modified as appropriate. Furthermore, the embodiments described above may be combined. For example, the dispensing container in the embodiment described above comprises a pair of aerosol containers 11, 11, but there may be only one aerosol container. In this case, the dispensing device and the connecting member 6 are each attached to one aerosol container. Furthermore, while the discharge container in the above-described embodiment had a cap-side contact portion and a cap-side restricting portion in the lower part of the cap, and a pressing member had a pressing-side restricting portion, the discharge container of the present invention may not have a cap-side contact portion, a cap-side restricting portion, or a pressing-side restricting portion. Alternatively, instead of the above-described embodiment, the cap 2 and the nozzle 38 may be integrally molded. In this case, for example, the nozzle cover portion 25 may be provided with the same configuration as the nozzle 38, and the connecting channel forming portion 46 may be inserted into the nozzle cover portion 25, thereby allowing the nozzle cover portion 25 to be used as a nozzle and connecting the channel of the liquid contents to the inside of the nozzle cover portion 25. Alternatively, the pressing member 5 and the nozzle 38 may be integrally molded. In this case, for example, it is preferable that the pressing member 5 has a flow path connecting the inside of the stem insertion cylinder portion 56 and the inside of the nozzle 38.

[0065] Furthermore, although the discharge container in the above-described embodiment had a sliding inclined portion (the inclined edge portion 33a of the pull-down projection 33) on the inner surface of the pressing operation portion 32, the sliding inclined portion may also be provided on the opposing portion of the aerosol container 11 or the opposing portion of the connecting member 6. For example, the outer surface of the operation arrangement portion 65 may be an inclined surface that slopes downward toward the aerosol container 11.

[0066] With regard to the embodiments described above, the present invention further discloses the following discharge container and discharge device. <1> A dispensing container comprising an aerosol container having a stem protruding from the top surface, and a dispensing device detachably attached to the top of the aerosol container, The dispensing device comprises a cap, a nozzle extending in the height direction of the dispensing container and having a discharge port formed at its tip, a pressing member having a stem insertion cylinder portion that is attached to the stem of the aerosol container, and a dispensing operation unit that pushes the pressing member downward toward the stem.
