Description

[Technical Field]

[0001] The present invention relates to a two-liquid dispensing container for dispensing two contents, and a two-liquid dispensing product using the same. [Background technology]

[0002] Patent Document 1 discloses an aerosol product for discharging two liquids, which has a double cylindrical pipe line, and by discharging a foamable composition from the inner pipe line and a viscous concentrate from the outer pipe line, the foamable composition can be covered with the viscous concentrate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6683431 Summary of the Invention [Problem to be solved by the invention]

[0004] In the two-liquid aerosol product of Patent Document 1, the foamable composition and the viscous concentrate are simultaneously discharged, so that the edge of the foamable composition is exposed and not covered by the viscous concentrate, as shown in Figure 4 of Patent Document 1.

[0005] An object of the present invention is to provide a two-liquid dispensing container that can produce two types of concentrate in a desired dispensing state. [Means for solving the problem]

[0006] The two-liquid dispensing container of the present invention comprises a first valve 22, 22A that dispenses a first content C1, a second valve 32, 32A that dispenses a second content C2, and a dispensing member 40, 40A that connects the first valve 22, 22A and the second valve 32, 32A so that they can be opened and closed together, and the dispensing member 40, 40A comprises a first discharge passage R1 from the first valve 22, 22A to the first discharge hole 71, a second discharge passage R2 from the second valve 32, 32A to the second discharge hole 72, and a time-delayed discharge means that blocks the second discharge passage R2 while the first content C1 is being dispensed and opens the second discharge passage R2 after the dispensing of the first content C1 is completed, and is characterized in that the second content C2 can be dispensed inside or on the surface of the dispensed first content C1.

[0007] The two-liquid discharging container is preferably provided with a nozzle attachment 75 for changing the discharging direction.

[0008] Furthermore, it is preferable that the discharge member 40A includes an inner nozzle 130 having a second discharge hole 72, and an outer nozzle 140 that covers the outside of the inner nozzle 130 and forms the first discharge hole 71 between itself and the inner nozzle 130. It is also preferable that the second discharge hole 72 protrudes further in the discharge direction than the first discharge hole 71.

[0009] The two-liquid discharging product of the present invention is characterized in that the first content C1 and the second content C2 are filled in any one of the two-liquid discharging containers 10, 10A described above. [Effects of the Invention]

[0010] The two-liquid dispensing container and two-liquid dispensing product of the present invention open the second dispensing passage to dispense the second contents after dispensing of the first contents is completed, so that the second contents can be dispensed into the inside of the dispensed first contents to cover the entire second contents with the first contents, or the second contents can be dispensed onto the surface of the dispensed first contents to place the second contents on the surface of the first contents, thereby achieving the desired dispense state.

[0011] Furthermore, if a nozzle attachment that changes the ejection direction is provided, it becomes easier to obtain the desired ejection state even when the two-liquid ejection product is used in a stationary state, for example.

[0012] When the discharge member includes an inner nozzle having a second discharge hole and an outer nozzle covering the outside of the inner nozzle and forming a first discharge hole between the inner nozzle and the outer nozzle, the first content is discharged in a generally cylindrical shape, making it easy to inject the second content into the interior. In particular, when the second discharge hole protrudes further in the discharge direction than the first discharge hole, it is easy to retain the first content that was previously discharged, it is easy to inject the second content into the first content, it prevents the second content from splashing when being discharged, and if the second content contains a volatile component, it is possible to suppress the diffusion of the odor of the volatile component.

[0014] Next, a two-liquid dispensing container 10 according to one embodiment of the present invention will be described in detail with reference to the drawings. As shown in Fig. 1, the two-liquid dispensing container 10 includes a first container 20 arranged upright, a second container 30 arranged in an inverted state above the first container 20, a dispensing member 40 that vertically connects the first container 20 and the second container 30, and a holder 95 that houses the first container 20, the second container 30, and the dispensing member 40. The first container 20 is filled with a first content C1, and the second container 30 is filled with a second content C2 to form a two-liquid dispensing product 1. Each component will be described in detail below.

[0015] The first container 20 includes a container body 21 having an opening 21a at the top end, and a first valve 22 that closes the opening 21a of the container body 21.

[0016] The container body 21 is made of a metal such as aluminum, and includes a bottom 21b, a body 21c rising from the outer peripheral edge of the bottom 21b, a shoulder 21d extending upward from the upper end of the body 21c while gradually reducing in diameter, and a neck 21e extending upward from the upper end of the shoulder 21d. The neck 21e has a constricted portion 21f approximately midway in the vertical direction. This constricted portion 21f is used when crimping and fixing the first valve 22. An opening 21a is provided at the upper end of the neck 21e.

[0017] The first valve 22 is a so-called aerosol valve, comprising a cylindrical stem 24 with a bottom having a stem hole 24a on the side, a housing 25 that accommodates the stem 24 so that it can move up and down, an elastic body (spring) 26 that constantly urges the stem 24 upward (outward), a roughly doughnut-shaped stem rubber 27 that closes the stem hole 24a with its inner circumferential surface before the stem 24 is pushed down (in), and that flexes its inner circumferential side to open the stem hole 24a when the stem 24 is pushed down (in), and a mounting cup 28 that fixes the housing 25 to the container body 21. However, the stem 24 is not always in communication with the inside of the container body 21 while it is being pushed down (in), but is a metered-volume valve that only dispenses a predetermined amount of the first content C1 even if the stem 24 is continuously pushed down.

[0018] Specifically, the first valve 22 further includes a stopper portion 91 provided at the bottom of the stem 24, which is inserted into a hole 25a1 provided in the bottom 25a of the housing 25, a seal material 92 provided below (upstream of) the bottom 25a of the housing 25, and a substantially cylindrical fixing member 93 that fixes the seal material 92 to the housing 25. A seal hole 92a that communicates between the inside of the container body 21 and the inside of the housing 25 is provided in the center of the seal material 92. Before the stem 24 is pushed down, the first content C1 flows into the housing 25 through this seal hole 92a. On the other hand, when the stem 24 is pushed down, the stopper portion 91 fits into the seal hole 92a and closes it (see S1 in FIG. 2). Closing the seal hole 92a forms a storage chamber S in the housing 25. Naturally, the supply of the first content C1 into the housing 25 stops. Therefore, the amount of the first contents C1 to be discharged naturally becomes the amount stored in the storage chamber S. When the stem 24 stops being pressed down and moves upward, the plug portion 91 releases the blockage of the seal hole 92a, and the first contents C1 again flows into the housing 25 (see S2 in FIG. 2).

[0019] The mounting cup 28 is generally cup-shaped with a bottom at the upper end, and a portion of the stem 24 protrudes upward from this bottom. The mounting cup 28 is fitted onto the neck 21e of the container body 21 and crimped in the direction of reducing its diameter, and is fixed to the container body 21. The first container 20 configured as described above is in a sealed state, and the first content C1 can be dispensed only through the first valve 22.

[0020] The second container 30 includes a container body 21 configured similarly to the first container 20, and a second valve 32 that closes the opening 21a of the container body 21. The second valve 32 is obtained by omitting the stopper 91, the sealant 92, and the fixing member 93 from the first valve 22. In other words, it is a simple aerosol valve (continuous valve) that does not include a constant-volume dispensing mechanism. However, to provide a configuration suitable for dispensing the liquid phase in an inverted state, a liquid phase introduction hole 25b is provided on the side of the housing 25. As the other components are the same as those of the first valve 22, the same reference numerals are used and detailed description will be omitted.

[0021] A shoulder cover 50 is attached to each of the first container 20 and the second container 30. The shoulder cover 50 includes a fixed cylinder 50a that fits securely onto the mounting cup 28, and a guide cylinder 50c that protrudes upward or downward from the fixed cylinder 50a. The guide cylinder 50c of the shoulder cover 50 on the first container 20 side is positioned on the outer periphery of the discharge member 40 and guides the vertical movement of the discharge member 40. The guide cylinder 50c of the shoulder cover 50 on the second container 30 side is also positioned on the outer periphery of the discharge member 40 and guides the shoulder cover 50 itself and the second container 30 to prevent tilting relative to the discharge member 40.

[0022] The discharge member 40 connects the stem 24 of the first valve 22 and the stem 24 of the second valve 32. Therefore, by pressing down the second container 30, the stem 24 of the first valve 22 and the stem 24 of the second valve 32 can be pressed down (pushed in) together, opening the first valve 22 and the second valve 32 together. The first valve 22 and the second valve 32 can be maintained in an open state. By stopping the pressing, the stem 24 of the first valve 22 and the stem 24 of the second valve 32 return to their original positions before being pressed down, closing the first valve 22 and the second valve 32 together. In other words, opening one valve also opens the other valve, and closing one valve also closes the other valve. The discharge member 40 connects the first valve 22 and the second valve 32 so that they can be opened and closed together.

[0023] This discharge member 40 is equipped with a first connection port 61a connected to the stem 24 of the first valve 22, a first discharge hole 71 for discharging the first content C1, a first discharge passage R1 connecting the first valve 22 to the first discharge hole 71, a second connection port 81 connected to the stem 24 of the second valve 32, a second discharge hole 72 for discharging the second content C2, a second discharge passage R2 connecting the second valve 32 to the second discharge hole 72, and a time-delayed discharge means that blocks the second discharge passage R2 when the first content C1 is being discharged and opens the second discharge passage R2 after the discharge of the first content C1 is completed.

[0024] The first discharge passage R1 and the second discharge passage R2 do not intersect with each other and are independent of each other, so that the first contents C1 and the second contents C2 do not mix with each other within the discharge member 40.

[0025] The time-delayed discharge means is a valve V1 that opens and closes the second discharge passage R2 in conjunction with the opening and closing of the second valve 32. Specifically, the valve V1 is provided in the second discharge passage R2, and is designed to close when the second container 30 is pressed down, and to open when the second container 30 stops being pressed down and returns to its original position.

[0026] Therefore, as shown in S1 of FIG. 2, when the second container 30 is pushed down, the first valve 22 and the second valve 32 are opened, and the first content C1 is discharged from the first discharge hole 71, but the second discharge passage R2 is closed (i.e., the valve V1 is activated), and the second content C2 does not reach the second discharge hole 72. The second content C2 discharged from the second valve 32 is stored in the storage chamber S provided upstream of the valve V1. When the second container 30 stops being pushed down, as shown in S2 of FIG. 2, the stem 24 returns to its original position by the elastic body 26, and the first valve 22 and the second valve 32 close at the same time. This stops the discharge of the first content C1 (discharge is completed). Meanwhile, the valve V1 is opened, and the second content C2 stored between the second valve 32 and the valve V1 is discharged from the second discharge hole 72.

[0027] The discharge member 40 configured as described above includes a main body 60, a discharge nozzle 70, and a stem mounting member 80. A first discharge passage R1 passes through the main body 60 and the discharge nozzle 70, and a second discharge passage R2 passes through the main body 60, the discharge nozzle 70, and the stem mounting member 80.

[0028] The substantially cylindrical main body 60 is provided with a first connection port 61a, a portion of the first discharge passage R1 (on the main body 60 side), and a portion of the second discharge passage R2 (on the main body 60 side). Specifically, the first connection port 61a is provided in the lower part of the main body 60, and a portion of the first discharge passage R1 is provided so as to communicate with the first connection port 61a. The portion of the first discharge passage R1 extends upward from the first connection port 61a and then extends laterally. A cylinder portion 63 is provided in the upper part of the main body 60 and is fitted onto the stem mounting member 80 so as to be slidable in the vertical direction. The internal space of this cylinder portion 63 constitutes most of the storage chamber S. A discharge hole 64 is provided in the lower part (downstream side) of the cylinder portion 63 to allow the second content C2 to flow downstream. This discharge hole 64 extends downward from the cylinder portion 63 and then extends laterally. A closing recess 65 is provided on the outer periphery of the upstream end of the outlet hole 64. When the second container 30 is pressed down, the closing recess 65 comes into contact with the stem mounting member 80 (the closing protrusion 84 described later), thereby blocking communication between the cylinder portion 63 and the outlet hole 64. In short, the closing recess 65 and the closing protrusion 84 constitute the valve V1.

[0029] The stem mounting member 80 includes a second connection port 81, a substantially dome-shaped lid portion 82 that closes the lower side (downstream side) of the second connection port 81, an introduction hole 82a provided in the lid portion 82 for introducing the second content C2 from the second connection port 81 into the cylinder portion 63, and a flange portion 83 that slidably abuts against the inner surface of the cylinder portion 63. A closing protrusion 84 is provided on the underside of the lid portion 82. The introduction hole 82a is provided on the side of the lid portion 82 and is not closed even when the closing recess 65 abuts against the closing protrusion 84, and always communicates between the second connection port 81 and the inside of the cylinder portion 63. A storage chamber S is formed when the closing recess 65 abuts against the closing protrusion 84 (see S1 in FIG. 2). This storage chamber S is constituted by an enclosed space formed from the stem hole 24a to the closing recess 65. Therefore, the second contents C2 are always discharged in the amount stored in the storage chamber S. In addition, since the stem 24 of the second valve 32 can be pushed in (opened) only after the closing recess 65 and the closing protrusion 84 come into contact and the second discharge passage R2 is cut off, the first contents C1 and the second contents C2 are not discharged at the same time, and the first contents C1 and the second contents C2 can be discharged in order.

[0030] The discharge nozzle 70 is a portion that protrudes laterally from the main body 60, and has a first discharge hole 71 and a second discharge hole 72 opening at its tip. In other words, it can be said that the first discharge passage R1 and the second discharge passage R2 each open at the tip of the discharge nozzle 70. As shown in FIG. 1, the portion where the second discharge hole 72 is provided protrudes further in the discharge direction than the portion where the first discharge hole 71 is provided. This state can also be said to be such that the second discharge passage R2 is extended in the discharge direction by the protruding portion 70a. It can also be said that the second discharge hole 72 protrudes further in the discharge direction than the first discharge hole 71.

[0031] The holder 95 includes a cylindrical body 95a and a bottom 95b that closes the lower end of the body 95a. The body 95a is open at its top. The upper end of the body 95a forms a cap mounting portion 95c for mounting a cap 96. A slit 95d is provided on the side of the body 95a, allowing the discharge nozzle 70 of the discharge member 40 to protrude outward. The slit 95d extends vertically. Its lower end is located below the discharge nozzle 70, allowing the discharge nozzle 70 to move downward. The height of the body 95a is preferably such that, when the first container 20, the second container 30, and the discharge member 40 are housed with the first container 20 facing downward, the bottom 21b of the second container 30 protrudes above the body 95a. A through-hole 95e is provided in the bottom 95b so that the bottom 21b of the first container 20 can be pressed when replacing the containers 20 and 30.

[0032] The first content C1 filled in the first container 20 contains a first agent (concentrate) of a two-component reactive content that exerts its effect by reacting two types of content, and a pressurizing agent for discharging the first agent, and is divided into a liquid phase and a gas phase. The fixing member 93 is open within the liquid phase, and the liquid phase is primarily discharged. Examples of two-component reactive content include two-component warming agents, two-component heat-generating agents, two-component cooling agents, two-component gelling agents, two-component film-forming agents, two-component adhesives, two-component hair dyes, and two-component perm agents. The pressurizing agent is liquefied gas, compressed gas, or a mixture thereof. Examples of liquefied gas include normal butane, isobutane, propane, and mixtures thereof such as liquefied petroleum gas, dimethyl ether, hydrofluoroolefins, and mixtures thereof. Examples of compressed gases include nitrogen, air, oxygen, hydrogen, carbon dioxide, and nitrous oxide, and are filled so that the pressure at 25°C is 0.2 to less than 1.0 MPa.

[0033] The second content C2 filled in the second container 30 contains a second agent (concentrate) of a two-liquid reactive content and a pressurizing agent for discharging the second agent, and is divided into a liquid phase and a gas phase. The pressurizing agent is preferably the same type as that filled in the first container 20, but a different type may also be filled.

[0034] In addition, the first content C1 and the second content C2 may be contents that exert at least two effects other than the two-liquid reaction type. Examples include insecticide and deodorant air freshener, sunscreen and antiperspirant, sunscreen and pest repellent, hand sanitizer and moisturizer, foundation and antiperspirant, and cosmetic coating and antiperspirant. Furthermore, both the first content C1 and the second content C2 are dispensed in foam, gel, cream, or other forms so that the concentrate remains in place rather than being sprayed. The dispense forms of the first content C1 and the second content C2 can be matched, for example, if the first content C1 is cream-like, the second content C2 can also be cream-like, or if the first content C1 is foam-like, the second content C2 can also be foam-like. When the first content C1 and the second content C2 are foam-like, the foaming properties can be different. Furthermore, the dispense forms of the first content C1 and the second content C2 may be different. For example, by making the first content C1 foamy and the second content C2 creamy or gel-like, it is possible to form an ejected product with cream inside the foam.Furthermore, by making the first content C1 creamy or gel-like and the second content C2 foamy, the foam injected inside the cream after ejection increases, making the surface of the ejected product smooth.

[0035] As an example of the second contents C2, by using a fragrance with a different scent from that of the first contents C1 in the second contents C2, the scent of the second contents C2 injected into the first contents C1 can be changed when exposed to the outside air. Furthermore, if the second contents C2 contain a component that emits a pungent odor, such as ammonia, the pungent odor can be reduced by wrapping it in the first contents C1. Furthermore, if the second contents C2 contain a component that decomposes and generates gas, such as hydrogen peroxide, by injecting it into the first contents C1, splashing during dispensing can be suppressed.

[0036] As described above, the two-liquid discharge product 1 of the present invention discharges the second content C2 after the discharge of the first content C1 is completed by the time-delayed discharge means. This makes it easier to inject the second content C2 into the discharged first content C1 than devices that simultaneously discharge the first content C1 and the second content C2. In particular, because the discharge nozzle 70 is provided with a protruding portion 70a, if the position of the two-liquid discharge product 1 is not shifted during the discharge operation, the protruding portion 70a will naturally be positioned within the discharged first content C1, making it easier to cover the second content C2 with the first content C1. Furthermore, by moving the position of the two-liquid discharge product 1 after discharging the first content C1, the second content C2 can be placed on the surface of the discharged first content C1. Since the second content C2 is not discharged as long as the second container 30 is continuously pressed, the second content C2 can be discharged at the user's preferred timing, making it easier to achieve the desired discharge state. Furthermore, since the first contents C1 and the second contents C2 can always be discharged at a predetermined ratio, the amount of one of the contents discharged does not become excessive, and the designed effect can be easily obtained.

[0037] FIG. 3 shows the nozzle attachment 75 attached to the discharge nozzle 70. The nozzle attachment 75 has two internal passages, and by attaching it to the tip of the discharge nozzle 70, it extends the first discharge passage R1 and the second discharge passage R2. Both of these internal passages extend downward. Therefore, the first content C1 and the second content C2, which flow sideways through the discharge nozzle 70, are discharged by changing their flow direction downward within the nozzle attachment 75. By changing the discharge direction of the first content C1 and the second content C2 in this way, the desired discharge state can be easily achieved even when the two-liquid discharge product 1 is used in a stationary state. Furthermore, it is easier to dispense onto the palm of a hand, a brush, or the like. By attaching this nozzle attachment 75, the first discharge hole 71 and the second discharge hole 72 are moved to the tip of the nozzle attachment 75, rather than the tip of the discharge nozzle 70. In FIG. 3A, the portion of the nozzle attachment 75 that will become the new second discharge hole 72 protrudes further than the portion that will become the new first discharge hole 71. That is, since the nozzle attachment 75 also has a protruding portion 75a, if the position of the two-liquid discharge product 1 is not shifted during the discharge operation, the protruding portion 75a will naturally be located within the discharged first contents C1, making it easier to cover the second contents C2 with the first contents C1. Note that, as shown in FIG. 3B, the protruding portion 75a does not have to be provided. In this case, it is easier to place the second contents C2 on the surface of the first contents C1.

[0038] 4 shows a two-liquid discharge product 1A according to another embodiment of the present invention. In this two-liquid discharge product 1A, a first container 20 and a second container 30 are arranged side by side. The first container 20 and the second container 30 are connected by a shoulder cover 50A having a connecting portion 50b that connects the fixed tubes 50a laterally, thereby fixing their relative positions. A cover member 97 is attached to the shoulder cover 50A. This cover member 97 protrudes above the discharge nozzle 70A and has a surrounding portion 97a that surrounds the discharge nozzle 70A from the side. This function as a cap to prevent the discharge nozzle 70A from being accidentally pushed in and also helps prevent the discharge nozzle 70A from tilting when pushed.

[0039] The first valve 22A and the second valve 32A are both continuous valves. Compared to the second valve 32 in Fig. 1, they differ in that they include a dip tube 29 and do not include a liquid phase introduction hole 25b, but otherwise have the same configuration.

[0040] In the discharge member 40A, the main body 60 is divided into two parts, one of which is connected to the first valve 22A and the other of which is fitted onto the stem mounting member 80 connected to the second valve 32A, thereby forming the valve V1.

[0041] Discharge nozzle 70A connects two separate main bodies 60. Discharge nozzle 70A includes a first connector 100 extending from main body 60 on the first valve 22A side, a second connector 110 extending from main body 60 on the second valve 32A side, and a nozzle member 120 connected to first connector 100 and second connector 110.

[0042] 5 and 6, the first connecting portion 100 and the second connecting portion 110 include a substantially cylindrical base portion 101 and a substantially cylindrical nozzle connecting portion 102 that protrudes in a direction (lateral direction) substantially perpendicular to the axial direction of the base portion 101. The nozzle connecting portion 102 is inserted into and connected to the nozzle member 120. A connecting portion passage J1 is provided within the first connecting portion 100, extending from the lower end of the base portion 101 to the opening at the tip of the nozzle connecting portion 102. The connecting portion passage J1 extends upward along the axial direction of the base portion 101 and then laterally along the axial direction of the nozzle connecting portion 102. The upstream side of the connecting portion passage J1 communicates with a passage within the main body 60.

[0043] The nozzle member 120 is a so-called double nozzle, and includes an inner nozzle 130 having a second discharge hole 72 at its axial tip, and an outer nozzle 140 that covers the inner nozzle 130 and forms a first discharge hole 71 between it and the inner nozzle 130. The inner nozzle 130 and the outer nozzle 140 are arranged concentrically.

[0044] The inner nozzle 130 protrudes in the discharge direction further than the outer nozzle 140. The inner nozzle 130 includes a cylindrical inner cylinder portion 131 and a flange portion 132 provided at the rear end of the inner cylinder portion 131. An inner-nozzle passage N2 is provided within the inner cylinder portion 131 along the axial direction. The tip opening of the inner-nozzle passage N2 is the second discharge hole 72. The rear end of the inner-nozzle passage N2 is closed. A lead-out hole 131a is provided on the side surface of the inner cylinder portion 131, connecting the outside of the inner cylinder portion 131 with the inner-nozzle passage N2.

[0045] The outer nozzle 140 includes a first insertion portion 141 into which the first connection portion 100 is inserted, a second insertion portion 142 into which the second connection portion 110 is inserted, and a cylindrical outer cylinder portion 143.

[0046] The cross-sectional shape of the outer cylinder portion 143 is circular on both the outer and inner circumferences. However, it is not limited to a circle, and may be a polygon. A rotationally symmetric shape such as a regular polygon is preferable. By accommodating the inner nozzle 130 inside the outer cylinder portion 143, an outer-nozzle inner passage N1 is formed between the inner nozzle 130 and the outer cylinder portion 143.

[0047] In this discharge member 40A, the first discharge passage R1 passes through the first valve 22A, the main body 60, the first connecting part 100, and the outer nozzle inner passage N1 to reach the first discharge hole 71, and the second discharge passage R2 passes through the second valve 32A, the main body 60, the second connecting part 110, and the inner nozzle inner passage N2 to reach the second discharge hole 72. The first discharge passage R1 and the second discharge passage R2 are independent of each other, and the contents C1 and C2 do not mix with each other within the dual-liquid discharge member 40.

[0048] In the two-component discharge product 1A having the above configuration, since the valve V1 (time-delayed discharge means) is provided in the second discharge passage R2, even if the discharge nozzle 70A is pushed in and the first valve 22A and the second valve 32A are both open, only the first content C1 is discharged from the first discharge hole 71 opening between the inner nozzle 130 and the outer nozzle 140, as shown in S1 of FIG. 7, and the second content C2 is not discharged. When the pushing of the discharge nozzle 70A is stopped and the hand is released from the discharge nozzle 70A, as shown in S2 of FIG. 7, the first valve 22A and the second valve 32A are both closed, and the first content C1 is no longer discharged (discharge is completed). At the same time, the valve V1 is opened, and the second content C2 is discharged from the storage chamber S through the inner nozzle 130 and the second discharge hole 72. Therefore, compared to when the first content C1 and the second content C2 are ejected simultaneously, it is easier to inject the second content C2 into the ejected first content C1. In particular, since the inner nozzle 130 protrudes from the outer nozzle 140, in other words, the second ejection hole 72 protrudes in the ejection direction more than the first ejection hole 71, a portion of the first content C1 ejected from between the inner nozzle 130 and the outer nozzle 140 is held on the outer periphery of the inner nozzle 130, and the second content C2 is ejected from the inner nozzle 130 in this state, so that the first content C1 can neatly encase the second content C2.

[0049] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be practiced with various modifications within the scope of the present invention. For example, a nozzle attachment 75 (see FIGS. 3A and 3B) may be attached to the discharge nozzle 70A of the two-liquid discharge container 1A in FIG. 4 to change the discharge direction.

[0050] 1 may be a continuous valve. Conversely, the first valve 22A of the two-liquid discharge product 1 of Fig. 4 may be a metered-dose valve. The discharge nozzle 70A of Fig. 4 does not necessarily have to have the inner nozzle 130 protrude beyond the outer nozzle 140.

[0051] Additionally, double containers can be used for both the first container 20 and the second container 30. Furthermore, although two containers (the first container 20 and the second container 30) are used for each of the two-liquid dispensing containers 10, 10A, a single container having two valves may also be used. In this case, two chambers or inner bags are provided within the single container to prevent the contents from mixing, and separate contents are dispensed from the two valves.
