Description

  The present invention relates to a discharge device that simultaneously discharges a plurality of liquid contents using a pump device.

  Conventionally, as a two-component hair cosmetic, for example, a two-component hair dye comprising a first agent containing an oxidative dye and a second agent containing an oxidant such as hydrogen peroxide is known. Yes. Further, as a hair bleach, a two-agent type consisting of a first agent containing an alkaline agent and a second agent containing hydrogen peroxide is known.

  In such hair cosmetics, from the viewpoint of storage stability, the first agent and the second agent are accommodated in separate containers, and the first agent and the second agent are mixed at the time of use. As an apparatus for discharging the first agent and the second agent at the same time, for example, Patent Document 1 describes a device in which an operation member capable of simultaneously pushing down these stems is attached to two aerosol containers.

  Further, in Patent Document 2, an adapter for connecting these discharge stems to one discharge hole is provided in two pump containers, and two pumps are simultaneously actuated by depressing an ejection button mounted on the adapter, The one that discharges two liquids simultaneously from one discharge hole is described. Furthermore, what was equipped with the trigger type pump is also known as a pump container which discharges two liquids simultaneously (patent document 3).

JP 2000-297018 A Japanese Utility Model Publication No. 5-29982 JP-A-8-229465

  However, aerosol containers are expensive to manufacture. At the time of disposal, since it is necessary to degas and then throw away as canned waste, it is complicated. Further, since the content liquid continues to be discharged while the stem is being pushed down, it cannot be discharged in a fixed amount.

  On the other hand, in a pump container, in order to push down the stem of two pump apparatuses simultaneously with one ejection button, a suitable force is required. In particular, since the discharge operation of hair cosmetics such as hair dyes is usually performed with one hand, the pump container for two liquids is grasped with one hand, and in that state, the ejection button is pressed with one finger. It is not possible to push down the stem of the pump device at the same time with a light operation.

  When two agents are discharged with a trigger pump as described in Patent Document 3, once the two agents are discharged with a trigger pump, the mixture of the two agents is placed in the cylinder of the trigger pump. Since it stays, there is a problem that the reaction of the two agents proceeds in the cylinder before the next use of the container.

  On the other hand, the present invention allows the liquid contents filled in a plurality of containers to be simultaneously discharged by a light and simple operation using a pump device, and prevents mixing of the agent in the cylinder. Objective.

  The present invention provides a pump and a cylinder and a piston for each container, and a lever to act on each piston at the same time when discharging the contents of each container from a plurality of containers using a pump device. If a single discharge valve is provided in front of the discharge hole and the discharge path of the internal solution communicating with each cylinder faces this discharge valve, mixing of the internal solutions in the cylinder can be prevented. It has been found that it is sufficient to provide a single discharge valve as a check valve for blocking the flow in the opposite direction to the discharge of the solution, so that the manufacturing cost can be reduced by reducing the number of parts.

That is, the present invention comprises a plurality of containers for storing the content liquid,
A pump device in communication with a plurality of containers, and a lever for operating a piston of the pump device;
A discharge device that simultaneously discharges the content liquid contained in each container from the discharge hole by a single lever operation,
The pump device includes at least a first cylinder communicated with the first container, a first piston provided in the first cylinder, a second cylinder communicated with the second container, and a second piston provided in the second cylinder. Have
The lever acts on each piston simultaneously,
Provided is a discharge device in which a discharge path of an internal solution communicating with each cylinder faces one discharge valve before a discharge hole, and content liquid discharged from each cylinder joins by passing through the discharge valve.

  Moreover, the hair cosmetics discharge tool by which the 1st container and 2nd container of the discharge apparatus of this invention are filled with the 1st agent and 2nd agent of hair cosmetics, respectively is provided.

  According to the discharge device of the present invention, a predetermined amount of each solution stored in a plurality of containers can be discharged simultaneously. In addition, a discharge valve is provided in front of the discharge hole so that the discharge path of each internal solution faces this discharge valve, so that mixing of the internal solutions in the cylinder can be prevented, and the direction opposite to discharge As a check valve for blocking the flow, it is sufficient to provide one discharge valve, so the number of parts can be reduced and the manufacturing cost can be reduced.

  Furthermore, in the discharge device of the present invention, when a lever lever that acts on the first piston and the second piston at the same time is provided as a lever, the discharge device is held with one hand when discharging the content liquid from each container. Then, the finger can be put on the lever and ejected by one light lever operation. That is, usually, the push button provided as an operation member in the aerosol container or the pump container is formed so as to be pressed with one finger, so that it is practically difficult to operate with a plurality of fingers, Therefore, when performing a discharge operation for two liquids, the operation feels heavy, but in the present invention, when a lever lever is provided, a plurality of fingers can be easily hung on the lever, The discharge operation can be performed with a light force. In particular, when the lever lever is formed wide, it is easy to operate with a plurality of fingers, and the discharge operation can be performed with a lighter force.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  1A and 1B are cross-sectional views of an initial state of a discharge device 100A of one embodiment of the present invention. 1A is a view of a cut surface parallel to the arrangement direction of the two containers 1A and 1B, and FIG. 1B is a view of a cut surface in a direction perpendicular to the aforementioned cut surface. 2A, 2B, and 2C are cross-sectional views illustrating the operation of the ejection device 100A.

  The discharge device 100A includes a first container 1A that contains a first content liquid A, a second container 1B that contains a second content liquid B, and a pump device 10 that is attached to these containers 1A and 1B. Yes. The mouth portions 2A and 2B of the containers 1A and 1B are detachably screwed to the container mounting portions 11A and 11B of the pump device 10, respectively.

  The pump device 10 includes a pump unit 9A including a cylinder 13A, a piston 16A, and the like, and a pump unit 9B including a cylinder 13B, a piston 16B, and the like. The first cylinder 13A communicated with the first container 1A and the first cylinder 13A A second cylinder 13B communicating with the two containers is provided in parallel. Each cylinder 13A, 13B extends in a direction perpendicular to the longitudinal direction of the containers 1A, 1B. Also, pistons 16A and 16B are provided in the cylinders 13A and 13B, respectively, and the pistons 16A and 16B are placed in the cylinders 13A in the measuring chambers 17A and 17B defined by the cylinders 13A and 13B and the pistons 16A and 16B. , 13B are provided with spring materials 19A, 19B that repel against the force of pushing into 13B.

  As shown in FIG. 1A, two cylinders 13A and 13B are provided in parallel, so that the two pistons 16A and 16B can be moved in the same direction for the operation of the two pump parts 9A and 9B. Thus, the two pistons 16A and 16B can be moved simultaneously by operating one lever lever 29, and the inner solution can be discharged simultaneously from the two pump portions 9A and 9B.

  Here, the cylinders 13A and 13B are made of synthetic resin such as high density polyethylene and polypropylene, and the pistons 16A and 16B are made of low density polyethylene and the like.

  The measuring chamber 17A in the first cylinder 13A communicates with the opening 2A of the first container 1A via the suction valve 18A, and the measuring chamber 17B in the base portion 13B of the second cylinder passes through the suction valve 18B. It communicates with the mouth 2B of the second container 1B.

  As the suction valves 18A and 18B, resin spring valves, one-point valves, three-point valves, ball valves, and the like can be used. Further, when the containers 1A and 1B are removed from the container mounting portions 11A and 11B during the use of the discharge device 100A, suction is performed so that the suction valves 18A and 18B remain attached to the containers 1A and 1B. The valves 18A and 18B are preferably provided at the mouths of the containers 1A and 1B. Thereby, when the containers 1A and 1B are removed from the container mounting portions 11A and 11B, it is possible to prevent air from being mixed into the containers 1A and 1B. Therefore, it is possible to prevent oxidative deterioration of the content liquid due to air mixing into the container, and when the containers 1A and 1B are attached to the container mounting portions 11A and 11B again and used, the content liquid is discharged from the discharge device 100A. It is possible to prevent so-called air biting, in which air is mixed and discharged and the discharge amount of the content liquid becomes unstable.

  The discharge nozzle 22 is formed perpendicular to the operation direction of the pistons 16A and 16B (that is, the longitudinal direction of the container). A discharge valve 26 is provided at the inner base of the discharge nozzle 22 before the discharge hole 23 as a check valve that closes when the cylinder becomes negative pressure and opens when the cylinder is pressurized. . The discharge passages 25A and 25B extending from the respective measuring chambers 17A and 17B to the discharge nozzle 22 are formed separately, but each discharge passage 25A and 25B faces the discharge valve 26, and each content liquid A is downstream of the discharge valve 26. , B join and are discharged.

  Therefore, according to the discharge device 100A, the single discharge valve 26 can serve as both the discharge valve for the first content liquid A and the discharge valve for the second content liquid B. Therefore, the manufacturing cost can be reduced by reducing the number of parts. Can be reduced. Furthermore, the flow of the internal solutions A and B is disturbed by the passage of the discharge valve 26, the inside of the discharge nozzle 22 becomes a mixing space 24, and both the internal solutions A and B are well mixed and discharged. .

  1B is a plan view of the discharge valve 26 viewed from the discharge hole 23 side. The discharge valve 26 is made of a bottomed cylindrical elastic member. A cross-shaped slit 27 is formed at the center of the bottom, and the slit 27 is opened when the bottom is deformed.

  A check valve operation limiting member 28 is attached to the inside of the discharge valve 26. When the discharge valve 26 is deformed so as to protrude to the opposite side of the check valve operation restricting member 28, the check valve operation restricting member 28 does not prevent the deformation, but the check valve operation restricting member 28 side In the case of deformation so as to protrude, the deformation is prevented and the discharge valve 26 is prevented from opening. As described above, when the check valve operation restricting member 28 is used in combination with the discharge valve 26, it is possible to reliably function as a check valve with a simple structure and to block the flow in the opposite direction.

In the present invention, instead of the discharge valve 26 made of an elastic member with a slit 27, or the combination of the discharge valve 26 and the check valve operation limiting member 28, a discharge valve provided in front of the discharge hole 23 is used as a pump. A check valve structure such as a one-point valve or a three-point valve used in a dispenser, or a ball valve using a metal ball or resin ball may be provided.

  One end 29 a of a plate-like lever-shaped lever 29 is rotatably connected to the outer base portion of the discharge nozzle 22. The lever lever 29 is wide and has a convex portion 29b that simultaneously contacts the protruding portions of the first piston 16A and the second piston 16B. Since the lever lever 29 is plate-shaped and wide, a plurality of fingers can be applied simultaneously. Therefore, when the other end 29c of the lever lever 29 is pushed into the containers 1A and 1B, the first end 29a connected to the base of the discharge nozzle 22 serves as a fulcrum, and the convex 29b serves as an action point. The first piston 16A and the second piston 16B can be simultaneously pushed in with a light force.

  Further, when the recess 29c is formed in the end portion 29c that serves as the pressing portion of the lever lever 29, the lever lever 29 is wide, so that a plurality of fingers can be hooked on the lever lever lever. Is even easier to push.

  On the other hand, as the first content liquid and the second content liquid filled in the containers 1A and 1B, various agents that start the reaction by mixing the two agents, for example, various hair dyes and bleaching agents in the form of two agents , Hot shaving agents, adhesives and the like.

  As the containers 1A and 1B, those which can be deformed and whose internal volume is reduced in accordance with the discharge of the content liquid are preferable. Examples of such containers include tube containers and pouch containers (bags) made of a soft flexible material such as polyethylene and polypropylene, and a movable intermediate dish that gradually rises from the container bottom to the pump device side in accordance with the discharge of the content liquid. And a container having a laminated structure of an inner layer and an outer layer, and a delamination bottle in which the inner layer peels and the inner layer container shrinks in volume when the inner layer container is depressurized or reduced in volume according to the discharge of the content liquid.

  Moreover, as a forming material of the containers 1A and 1B, those having an oxygen barrier property are preferable according to the type of content liquid to be stored. For example, when this discharge device 100A is used as a two-component hair dye discharge tool comprising a first agent containing an oxidative dye and a second agent containing hydrogen peroxide, the second container 1B containing the first agent. The outer layer is formed from a polyolefin resin such as low density to high density polyethylene or polypropylene, and the intermediate layer is an oxygen gas barrier layer such as an ethylene / vinyl alcohol copolymer film or a polyamide film using metaxylenediamine, preferably moisture. A container having a laminated structure (Japanese Patent Application Laid-Open No. 2002-345548) is preferably formed from a cyclic polyolefin layer having excellent barrier properties and barrier properties for oxidation dyes, and the inner layer is a polyolefin layer. In addition, the first container 1A for storing the second agent includes an oxygen gas-permeable container (Japanese Patent Laid-Open No. 2002-87418) in which an outer layer is formed from low-density polyethylene and an inner layer is formed from linear low-density polyethylene. It is preferable to do.

  In order to use the discharge device 100A, first, the pump device 10 is grasped by placing a finger on the lever lever 29 with one hand, and the lever lever 29 is pushed in as indicated by an arrow in FIG. 2A. Thereby, the first piston 16A and the second piston 16B are simultaneously pushed into the respective cylinders 13A and 13B, the spring materials 19A and 19B are contracted, and the respective measuring chambers 17A and 17B are pressurized. Therefore, the air in the measurement chambers 17A and 17B is discharged through the discharge valve 26 via the discharge paths 25A and 25B.

  Next, the pushing of the lever lever 29 is released. Then, as shown in FIG. 2B, the pistons 16A and 16B are pushed back by the repulsive force of the spring material 19 that has been contracted. As a result, the volume of the measuring chambers 17A and 17B is increased and the inside thereof is depressurized, so that the suction valves 18A and 18B are opened, and the content liquids A and B are respectively measured from the first container 1A and the second container 1B. It is sucked into the chambers 17A and 17B. At this time, a force for deforming the metering chambers 17A and 17B is also applied to the discharge valve 26, but the check valve operation limiting member 28 existing on the discharge passages 25A and 25B (upstream side) prevents this deformation. The valve 26 remains securely closed without opening.

  Next, as shown in FIG. 2C, the lever lever 29 is pushed in again. As a result, the measuring chambers 17A and 17B are narrowed, the suction valves 18A and 18B are closed, the discharge valve 26 is opened, and the first content liquid A sucked into the first measuring chamber 17A and the second measuring chamber are sucked. The second content liquid B that has been discharged is simultaneously discharged from the discharge hole 23 in a mixed state.

  Thereafter, by repeatedly pushing and releasing the lever lever 29, the first content liquid A and the second content liquid B can be discharged simultaneously from the discharge hole 23.

  In this case, since the discharge amounts of the first content liquid A and the second content liquid B are determined by the effective areas of the pistons 16A and 16B and the movement amounts of the pistons 16A and 16B, respectively, the effective areas of the pistons 16A and 16B or their movements are determined. By appropriately adjusting the amount, the mixed liquid of the first content liquid A and the second content liquid B can be quantitatively discharged. Furthermore, since the convex portion 29b of the lever lever 29 is in contact with the protruding portions of the pistons 16A and 16B over the entire stroke of the lever lever 29, the discharge amount of the first content liquid A and the discharge amount of the second content liquid B The ratio of the amounts is determined by the ratio of the effective areas of the pistons 16A and 16B. Therefore, the user can make the mixing ratio of the first content liquid A and the second content liquid B constant regardless of the discharge amount of the mixed liquid, and adjust the pushing amount of the lever lever 29. A desired amount of a mixed solution can be easily obtained at a constant mixing ratio by simply using this method.

  Further, since the levers 29 are used to push in the two pistons 16A and 16B at the same time, the first content liquid A and the second content liquid B can be discharged by a light lever operation by the lever principle.

  3A is a modification of the discharge device 100A of FIGS. 1A and 2B, FIG. 3B is a side view thereof, and FIG. 3C is a bottom view thereof. In the discharge device 100 </ b> B, a pair of opposed gripping portions 30 are formed in the main body housing 12 of the pump device 10. The grip 30 is a plate-like member extending from the main body housing 12 in the longitudinal direction of the containers 1A, 1B so as to sandwich the side surfaces of the containers 1A, 1B attached to the pump device 10 from both sides.

  By providing the grip portion 30 in this manner, it is easy to apply a force to the lever lever 29 when the discharge device 100B is gripped by hand and the lever lever 29 is pushed in the direction of the arrow. In particular, when the containers 1A and 1B are tube containers or pouch containers made of a soft flexible material, force is applied to the lever lever 29 while directly holding the containers 1A and 1B and the lever lever 29 by hand. Since the containers 1A and 1B are bent, it is difficult to apply a force, but the grip lever 30 makes it easy to push the lever lever 29.

  Further, by providing the grip portion 30, when using the discharge device 100B, the containers 1A and 1B can be attached to the pump device 10 along the grip portion 30, so that the attachment of the containers 1A and 1B is facilitated. Even if an unexpected force is applied to the containers 1A and 1B when the discharge device 100B is used, the containers 1A and 1B can be prevented from being detached from the pump device 10.

  The discharge device 100C of FIGS. 4A, 4B, and 4C includes a gripping portion 30, similar to the discharge device 100B of FIGS. 3A, 3B, and 3C. The discharge device 100C pumps the containers 1A and 1B. In addition to being detachable from the pump 10, the pump device 10 itself can be easily provided with a lower housing 12b having a gripping portion 30 and a container mounting portion, an upper housing 12c having a built-in cylinder, a lever lever 29, and a discharge nozzle 22. It can be disassembled and assembled. This facilitates cleaning of the pump device 10.

In the discharge device 100D, as shown in FIG. Extends the grip 30 to the ends of the containers 1A, 1B. Therefore, in the discharge device 100D, a support plate 31 is provided between the pair of gripping portions 30 facing each other in order to prevent deformation due to the bending of the gripping portion 30.

  6A, 6B, and 6C are provided with a case 32 surrounding the containers 1A and 1B in place of the grip portion 30. This case is detachably fitted to the main body housing 12 of the pump device 10.

  The present invention can take various aspects. For example, in the discharge device 100A of FIGS. 1A and 1B, the discharge nozzle 22 may be formed in parallel with the operation direction of the pistons 16A and 16B. Further, the angle between the operation direction of the pistons 16A and 16B and the longitudinal direction of the containers 1A and 1B is not limited to be vertical.

  Further, in the discharge device 100A, a third container and a third cylinder communicating with the third container may be provided, and the third piston in the third cylinder may be pushed by the lever lever 29. As a result, the first, second, and third content liquids can be discharged simultaneously by one lever operation.

It may be covered. Thereby, when applying hair cosmetics directly to the hair from the discharge nozzle 22, the contact area of the nozzle with the scalp is widened, and the stimulation to the scalp can be eased. Further, by passing the slit 41 or the mesh, the flow of the first agent and the second agent in the discharge nozzle 22 is disturbed, and both the agents after discharged from the nozzle can be easily mixed.

  As shown in FIGS. 8A and 8B, a cylindrical applicator 43 provided with a brush portion 42 around the discharge hole 23 may be attached to the discharge nozzle 22. Thereby, it becomes easy to perform partial dyeing etc. directly using this discharge device 100A.

  As shown in FIGS. 9A and 9B, a plurality of brush teeth 45 may be erected on a rectangular base 44, and a brush 46 having a discharge hole 23 in the center may be attached to the discharge nozzle 22. Thereby, it becomes easy to dye the whole hair using this discharge device 100A. In addition, as shown in FIGS. 10A and 10B, a brush 47 erected in the direction in which the containers 1 </ b> A and 1 </ b> B stand is implanted around the slit-like discharge holes 23 extending in the arrangement direction of the two containers 1 </ b> A and 1 </ b> B.
