Summary of the Invention
Problems to be Solved by the Invention
[0004] In the container of Patent Document 1, when the operation lever is pressed, it is discharged at once. Without pressing it in a full stroke, the inside of the chamber may overflow with the discharge from the aerosol container body. However, if it is not pressed in a full stroke, only the liquid is discharged from only one container body, so that the two liquids stored in each container body do not come out evenly, and there is a problem that when the non - uniform mixture of the two liquids is applied to the hair, the dyeing result is not good. Furthermore, if the nozzle of the container in Patent Document 1 is replaced with a configuration in which the hair dye mixture is dispensed from a brush connected to a mixing nozzle, when the contents of the aerosol container are dispensed, the brush becomes full of the contents, and it becomes impossible to press the brush until the two liquids are dispensed evenly, resulting in the problem of only the contents of one container being consumed (uneven dispensing).
[0005] The objective of the present invention is to provide a double aerosol container that enables even dispensing by dispensing the contents of a pair of aerosol containers with a delay after the push button is pressed down. [Means for solving the problem]
[0006] The first means comprises a pair of aerosol containers 2 having a stem 6 with an upper end opening, A nozzle head 40 is provided, which is connected to the stems 6 of the pair of aerosol container bodies 2, and has a nozzle 48 protruding from a communication chamber C that communicates with these stems 6, This nozzle head 40 and the upper part 4 of the pair of aerosol containers 2 are surrounded by a cover member 10 that holds these aerosol containers 2 together, The nozzle head 40 is equipped with a push button member 50 which is attached to the cover member 10 on the upper side, The push button member 50 has a push button 70a and a pressing piece 70b whose base end 84 is connected to the push button 70a, and is formed such that the pressing piece 70b presses the nozzle head 40 with a delay after the push button 70a is pressed down. Occasionally, The pressing piece 70b is an elastic piece supported in a cantilevered manner with its tip portion 88 as a free end, and is designed to deform in the opposite direction to the direction of contact when the tip portion 88 is pressed against the nozzle head 40 by the pressing operation of the push button 70a. The push button member 50 has a stopper 76 above the tip portion 88 for pressing down on the tip portion 88 from above when the push button 70a is pressed down.
[0007] In this method, as shown in Figure 1(B), a nozzle head 40 is connected to the stem 6 of a pair of aerosol containers 2, the nozzle head 40 and the upper part of the pair of aerosol containers 2 are surrounded by a cover member 10, and a push button member 50 is provided on the upper side of the nozzle head 40, which is assembled to the cover member 10. The push button member 50 has a push button 70a and a pressing piece 70b whose base end 84 is connected to the push button 70a. As shown in Figures 4(A) and 4(B), the pressing piece 70b is formed to press the nozzle head 40 with a delay after the push button 70a is pressed down. This structure allows the contents to be dispensed by starting to press the push button 70a and then pressing it further, thereby enabling the contents to be dispensed evenly from the pair of aerosol containers 2. Furthermore, in this means, as shown in Figure 2(A), the pressing piece 70b is an elastic piece supported in a cantilevered manner with its tip portion 88 as the free end, and is designed to deform in the opposite direction to the direction of contact when the tip portion 88 is pressed against the nozzle head 40 by the pressing operation of the push button 70a. Furthermore, the push button member 50 has a stopper 76 above the tip portion 88 for pressing down on the tip portion 88 from above when the push button 70a is pressed down. With this structure, the pressing pressure of the push button 70a can be adjusted by utilizing an elastic piece supported in a cantilevered manner with the tip 88 as the free end. This appropriately enables the dispensing of the contents of each aerosol container 2 with a delay of one beat from the start of the push button 70a pressing operation, and ensures that these dispensed materials are dispensed evenly.
[0010] The 2 The means is, 1 The push button member 50 has a means of operation, and the push button member 50 is rotatably connected to an assembly 52 assembled and fixed inside the cover member 10 via a hinge portion 68 to a leaf spring-shaped operating lever 70. When viewed from above, a separation line 82 is drilled into the operating lever 70, thereby forming a pair of pressing pieces 70b extending in a direction perpendicular to the rotation axis A at two locations spaced apart from each other in the direction of the rotation axis A of the operating lever 70, and the remaining part of the operating lever 70 is designated as the push button 70a.
[0011] In this configuration, as shown in Figure 1(B), the push button member 50 is rotatably connected to an assembly 52, which is assembled and fixed inside the cover member 10, via a hinge portion 68 to a leaf spring-shaped operating lever 70. As shown in Figure 1(A), a separation line 82 is drilled into the operating lever 70, thereby forming a pair of pressing pieces 70b extending in a direction perpendicular to the rotation axis A at two locations spaced apart from each other in the direction of the rotation axis A of the operating lever 70 when viewed from above, and the remaining portion of the operating lever 70 is designated as the push button 70a. This structure allows the pressing pressure of the push button 70a to be adjusted by using the pressing pieces provided at two locations in the direction of the rotation axis of the leaf spring-shaped operating lever 70.
[0012] The3 The means has the means of 2 and, The tip portion 88 of the pressing piece 70b is positioned closer to the rotation axis A than the base portion 84 of the pressing piece 70b. , Adjacent to this tip portion 88, the stopper 76 is formed on the lower surface of the push button 70a, and the tip portion 88 is arranged lower than the stopper 76, and when the push button 70a is pushed down, the tip portion 88 is configured to be inserted into the gap G between the stopper 76 and the upper surface 47 of the nozzle head 40.
[0013] In this means, as shown in FIGS. 4(A) to 4(C), The tip 88 of the pressing piece 70b is positioned closer to the axis of rotation A than the base end 84 of the pressing piece 70b, The tip portion 88 of the pressing piece 70b is inserted into the gap G between the stopper 76 and the upper surface 47 of the nozzle head 40 by the pressing operation of the push button 70a. According to this structure, the nozzle head 40 can be efficiently pushed in by utilizing the lever principle. As a result, an even mixture can be discharged all at once with a one-tempo delay from the start of the pressing operation of the push button 70a.
Effect of the Invention
[0014] According to the present invention, it is possible to discharge the contents of a pair of aerosol container bodies with a delay in the pressing operation of the push button, and the contents from both container bodies can be discharged evenly.

Best Mode for Carrying Out the Invention
[0016] Figs. 1 to 4 show a two - part aerosol container according to an embodiment of the present invention. As shown in Fig. 1(B), this container is composed of a pair (a left - right pair in the illustrated example) of aerosol container bodies 2, a cover member 10, a nozzle head 40, and a push - button member 50. The above - mentioned cover member 10, nozzle head 40, and push - button member 50 can be formed of, for example, a synthetic resin material. In this specification, the lower side of Fig. 1(A) is expressed as "front", the upper side of the same figure is expressed as "rear", and the left - right sides of the same figure are expressed as "left - right".
[0017] The pair of aerosol container bodies 2 are aerosol cans each containing a different kind of content liquid, and for example, they contain a drug used by mixing the content liquid such as a hair dye container. From the head 4 of each aerosol container body 2, a stem 6 with an upper - end opening stands up so as to be able to move up and down. The pair of aerosol container bodies 2 are held and fixed in the cover member 10 by a holder 12 described later in a side - by - side state.
[0018] The cover member 10 surrounds the nozzle head 40 and the upper parts of the pair of aerosol container bodies 2, and has a role of holding these aerosol container bodies 2 together. The cover member 10 of the present embodiment is composed of a holder 12 and a cover cylinder 20 as shown in Fig. 1(B). However, this structure can be appropriately changed.
[0019] The holder 12 is a member that surrounds the heads 4 of the pair of aerosol containers 2, and a retaining wall 16 is suspended from an upper wall portion 14 that rests on the heads 4, and the retaining wall 16 is tightly fitted onto the heads 4 of the aerosol containers 2. A claw portion 18 is attached to the upper half of the outer circumferential surface of the holder 12. In the illustrated example, as shown in Figure 2(A), the inner surface of the retaining wall 16 is provided with a retaining rib p that engages with the head 4 of the aerosol container body 2, and the outer surface of the retaining wall 16 is provided with a pressure contact rib q that is pressed against the cover cylinder 20, which will be described later.
[0020] The lower part of the cover cylinder 20 is fitted onto the outer circumference of the holder 12. The cover cylinder 20 in the illustrated example is an oval-shaped cylinder when viewed from above, as shown in Figure 1(A), but its shape can be changed as appropriate. The front of the cover cylinder 20 has a front opening 22A for inserting the nozzle 48, which will be described later, and the rear of the cover cylinder 20 has a rear opening 22B for operating the operating lever 70, which will be described later. In the illustrated example, a pair of inwardly protruding portions 24 are provided projecting inward from the lower edges of the front opening 22A and the rear opening 22B, as shown in Figure 2(A). Furthermore, as shown in Figure 1(B), a pair of engagement holes 26 for fitting the claw portion 18 are opened in the left and right walls of the cover cylinder 20, and a finger rest portion 28 is attached just above each engagement hole 26. Furthermore, a pair of upward-facing stepped portions 30 are formed on the upper side of the pair of finger rest portions 28, and parallel flat wall portions 32 extend upward from these stepped portions 30. Furthermore, a convex receiving portion i is provided at the upper end of the inner surface of these flat wall portions 32. In the illustrated example, the convex receiving portion i is formed as part of the closing plate portion 36, which will be described later. In this embodiment, as shown in Figure 1(A), a pair of substantially U-shaped closing plate portions 36 are connected to the upper end of the cover cylinder 20 when viewed from above. These closing plate portions 36 serve to close the gap between the upper end of the cover cylinder 20 and the top plate 56, which will be described later, and are formed extending between the first end portion e1 adjacent to the front opening 22A and the second end portion e2 adjacent to the rear opening 22B.
[0021] The nozzle head 40 is connected to the stems 6 of the pair of aerosol containers 2, and a nozzle 48 is provided protruding forward from a communication chamber C that communicates with these stems 6. In this specification, the term "communicating chamber" includes not only the type shown in the illustration, which mixes the contents flowing in from a pair of aerosol containers inside and discharges the mixture (mixing chamber), but also a type in which the inside of the chamber is separated into two chambers, each communicating with a pair of aerosol containers, and nozzles are provided protruding from each chamber (separated chamber). In the case of the separated type, the contents from the two nozzles protruding from the chamber can be discharged, for example, onto the user's palm and mixed on the palm. In this embodiment, the nozzle head 40 is formed of a lower half 40a and an upper half 40b, as shown in Figure 1(B). The lower half 40a has a tall, dish-shaped bottom 42 that is long in the left-right direction and has an upright outer circumference, and a pair of left and right fitting cylindrical portions 44 that hang down from the bottom. Each fitting cylindrical portion 44 is fitted onto the stem 6 of the pair of aerosol container bodies 2. The upper half 40b has a long, cylindrical housing 46 with a top that extends in the left-right direction, and a nozzle 48 that protrudes forward from the housing 46, and the lower end of the housing 46 is fitted to the outer circumference of the bottom 42. The bottom portion 42 and the housing 46 form a mixing-type communication chamber C for mixing the discharged material from the pair of aerosol containers 2. In the illustrated example, the housing 46 and the bottom portion 42 are pivotally connected via an integrated hinge 45, as shown in Figure 2(A). However, this structure can be modified as appropriate.
[0022] The push button member 50 is positioned above the nozzle head 40 and has the function of being a button that is pressed down from above, and also has the function of pushing the nozzle head 40 in with a slight delay after the push operation. In this specification, the phrase "delayed by the pressing operation" means "delayed from the moment the pressing begins." This push button member 50 is assembled to the cover member 10 on the upper side of the nozzle head 40. In this embodiment, the push button member 50 has an assembly 52 assembled and fixed inside the cover member 10, and a leaf spring-shaped operating lever 70 rotatably connected to the assembly 52 via a hinge portion 68. Furthermore, by drilling a separation line 82 into the operating lever 70, a portion of the operating lever 70 is made into a pressing piece 70b for pushing in the nozzle head 40, while the remaining portion of the operating lever 70 forms a push button 70a for pressing down.
[0023] The assembly 52 can have any structure as long as it is fixedly attached to the cover member 10 to support the operating lever 70. As shown in Figure 1(B), the assembly 52 of this embodiment has a horizontal top plate 56 with a shape corresponding to the inner circumferential surface of the cover cylinder 20, and a pair of mounting wall portions 53 that are suspended from at least both left and right ends of the top plate 56. The mounting wall portion 53 is then fixed to the corresponding location on the cover cylinder 20 (in the illustrated example, the inner surface of the flat wall portion 32). In the illustrated example, contact ribs j are attached to the outer surfaces of each of the pair of mounting wall portions 53. These contact ribs j abut against the inner surface of the flat wall portion 32 and are locked to the lower surface of the convex receiving portion i. As shown in Figure 3(A), the top plate 56 has a rectangular notch 66 that opens to the rear, corresponding to the rear opening 22B, and an operating lever 70 is connected to the front edge of this notch 66 via a hinge portion 68, which will be described later. The notch 66 is cut out from the rear edge s1 of the top plate 56 to near the front edge s2, leaving a strip-shaped top plate portion 56b (the portion between the imaginary lines k1 and k2) between it and the front edge. The tabletop 56 in the illustrated example is formed from a strip-shaped tabletop portion 56b and a pair of semicircular tabletop portions 56a. In this embodiment, as shown in Figure 2(B), a top plate-side inclined wall portion 58 is projected downward and backward from the rear end of the strip-shaped top plate portion 56b, and an operating lever 70 is connected to the lower end of this top plate-side inclined wall portion 58 via a hinge portion 68. Furthermore, a connecting wall portion 60 is suspended from the front end of the strip-shaped top plate portion 56b, and a front wall portion 64 is suspended from the lower end of the connecting wall portion 60 via an outward overhang portion 62. In the illustrated example, a side plate 67 that is continuous with the side edge of the notch 66 and a rib r adjacent to the side plate 67 are vertically attached from the semicircular top plate portion 56a, as shown in Figure 3(B).
[0024] The operating lever 70 is a leaf spring rotatably connected to the top plate 56 of the assembly 52 via the hinge portion 68. In the illustrated example, the operating lever 70 is rectangular in shape when viewed from above, as shown in Figure 3(A), and protrudes further back than the rear edge s1 of the top plate 56. However, these structures can be modified as appropriate. As shown in Figure 2(A), the operating lever 70 in the illustrated example has a horizontal plate portion 74 projecting backward from the hinge portion 68 via a lever-side inclined wall portion 72 that extends upward and backward. As shown in Figure 3(B), the horizontal plate portion 74 in the illustrated example is a curved plate in which the central portion is lower and recessed compared to the left and right ends, and a pair of reinforcing wall portions 71 are vertically attached from its left and right ends. As shown in Figure 1(A), the operating lever 70 is provided with a raised rib 78 that crosses the horizontal plate portion 74 in the left-right direction. The horizontal plate portion 74 is divided into a front plate portion 74a and a rear plate portion 74b by the raised rib 78. Furthermore, the lower surface of the front plate portion 74a shown in Figure 2(B) is a stopper 76 that restricts the movement of the tip portion 88 of the pressing piece 70b, which will be described later. It is formed so as to abut the tip portion 88 from above when the operating lever 70 is pressed down, as shown in Figure 4(B).
[0025] In this embodiment, a U-shaped separation line 82 is drilled into the operating lever 70 when viewed from above, thereby forming a pair of pressing pieces 70b extending in a direction perpendicular to the rotation axis A at two locations spaced apart from each other in the direction of the rotation axis A of the operating lever 70, and the remaining part of the operating lever 70 is a push button 70a. The pair of pressing pieces 70b in the illustrated example are symmetrical and have equal elastic forces, and are designed to uniformly press down the pair of aerosol containers 2. However, the above structure can be modified as appropriate; for example, the number of pressing pieces 70b may be one or three or more. Furthermore, the "separation line" can have any structure as long as the pressing piece formation area and the surrounding leaf spring plate portion are separated when viewed from above. The illustrated separation line 82 is formed by two lateral line portions 82b extending in a direction perpendicular to the rotation axis A, and a forward line portion 82a that is continuous with the front ends of these lateral line portions 82b.
[0026] As shown in Figure 2(B), the pressing piece 70b is a cantilevered elastic piece with its base end 84 supported on the push button 70a side and its tip end 88 being a free end. In the illustrated example, a pressing protrusion 90 is provided protruding from the tip portion 88, and when the operating lever 70 is pressed down, it rotates around the hinge portion 68, causing the pressing protrusion 90 to press against the upper surface 47 of the nozzle head 40 (see Figure 4(A)). The pressure projection 90 in the illustrated example has a rounded shape when viewed from the side, as shown in Figure 2(B). Furthermore, the pressing piece 70b has enough flexibility to deform in the opposite direction to the contact direction and come into contact with the stopper 76 due to the reaction force of the contact force of the tip portion 88 against the nozzle head 40. In other words, by pressing the tip portion 88 against the nozzle head 40, the tip portion 88 is displaced in the opposite direction to the direction of pressure, as shown by the dashed line in Figure 4(B), compared to the position (virtual position v) when the pressing piece 70b rotates around the pivot point 81 without deformation. The pressing force of the push button 70a can be adjusted by deforming the pressing piece 70b in the opposite direction to the direction of contact. The tip portion 88 is positioned lower than the stopper 76, and a height difference h is provided between the tip portion 88 and the stopper 76, as shown in Figure 2(B), which is an upward clearance for the tip portion 88. The aforementioned configuration enables the dispensing of the contents from the nozzle head 40 with a slight delay from the start of pressing down the push button 70a. The technical significance of this can be further explained by supplementing what was stated in the problem the invention aims to solve. Conventional aerosol containers, when the push button is pressed, release the contents all at once, potentially causing excessive dispensing and splashing. Therefore, some users may be afraid of over-dispensing and refrain from fully pressing the lever, resulting in an incomplete press. However, when this operation is performed with a dual aerosol container, one aerosol container (2) will dispense its contents before the other, filling the connecting chamber with the contents of one container. Even if the other aerosol container then dispenses, the ratio of the two liquids will not be equal. In the present invention, even if the button is pressed only partially, it will not push in the nozzle head 40 of the aerosol container 2, forcing the user to press the push button 70a with a full stroke. Since the pressing pressure does not increase suddenly, the user can press the full stroke without fear, thereby enabling the two liquids to be dispensed evenly.
[0027] In this embodiment, as shown in Figure 2(B), a horizontal plate portion 74 is raised at the rear of the pressing piece 70b, and the front end of this raised portion 80 is connected to the base end portion 84 of the pressing piece 70b, forming a fulcrum portion 81 that supports the pressing piece 70b. This fulcrum portion 81 is formed to be elastically bendable, and this deformation allows the pressing piece 70b to rotate around the fulcrum portion 81 as shown by the dashed line in Figure 2(B). Furthermore, the tip portion 88 is provided projecting from the base portion 84 via a bent portion 86 that curves forward and downward. This tip portion 88 is positioned lower than the base portion 84 and closer to the axis of rotation A than the base portion 84, so that it is located near the gap G between the upper surface 47 of the nozzle head 40 and the stem 6. Furthermore, as shown in Figures 4(A) and 4(B), the operating lever 70 is configured such that when it is rotated around the hinge portion 68 by a downward operation, the tip portion 88 is inserted into the gap G between the stopper 76 and the upper surface 47 of the nozzle head 40.
[0028] In this embodiment, the push button 70a is formed on the operating lever 70 in a portion other than the area where the pressing piece is formed. However, this structure can be modified as appropriate. For example, instead of an operating lever that rotates around the hinge, a push-button member that slides perpendicularly to the cover cylinder 20 may be provided, and the push-button may be attached to the upper surface of the member.
[0029] In the above configuration, when the push button 70a of the operating lever 70 is pressed down from the state shown in Figure 2(A), the operating lever 70 rotates around the rotation axis A. As a result, as shown in Figure 4(A), the pressing protrusion 90 attached to the tip 88 of the pressing piece 70b presses against the upper surface 47 of the nozzle head 40. Due to the reaction force of this pressing force, the pressing piece 70b elastically deforms and the tip 88 retracts upward, so in this state, the nozzle head 40 is not yet pressed down. Furthermore, as the operating lever 70 rotates around the hinge portion 68, the pressing protrusion 90 slides along the upper surface 47 of the nozzle head 40, and the tip portion 88 enters the gap G between the upper surface 47 and the stopper 76, and is held between the upper surface 47 and the stopper 76. In this state, if the operating lever 70 is rotated further, the nozzle head 40 will be pushed down. As a result, the contents of each aerosol container 2 are dispensed with a slight delay from the start of the pressing operation, the contents flow into the communication chamber C, are mixed evenly within the communication chamber C, and the mixture is dispensed from the nozzle 48.
[0030] According to the above configuration and operation, the push button member 50 has a push button 70a and a pressing piece 70b whose base end 84 is connected to the push button 70a. The pressing piece 70b is formed to press the nozzle head 40 with a delay after the push button 70a is pressed down. Therefore, the contents are dispensed by pressing the push button 70a and then pressing it further, thereby enabling the contents to be dispensed evenly from the pair of aerosol containers 2. Furthermore, by utilizing the elastic piece supported in a cantilevered manner with the tip portion 88 as the free end, the pressing pressure of the push button 70a can be appropriately adjusted.
