Specifically, the present invention relates to a two-liquid mixing / discharging device for discharging a foamed content by mixing compositions stored independently, and a discharge product using the same.

Two-component mixing contents are known in which two types of compositions are stored separately and mixed immediately before use. In general, the contents for mixing these two liquids are prepared by dividing a reactive active ingredient into two compositions and mixing the two compositions at the time of use to make the active ingredient redox or the like. The chemical reaction is caused and the effect is demonstrated. Therefore, it is necessary to store each composition as independently as possible until just before use. On the other hand, if the two liquids are taken out from two tubes or the like and mixed immediately before use, the operation becomes complicated.
As a discharge product that solves these problems, for example, as shown in Patent Documents 1 to 4 and 6, two aerosol containers for storing the respective compositions, and aerosol valves of two aerosol containers are connected, and two 2. Description of the Related Art An aerosol product for discharging two liquids comprising a two-liquid mixing / discharging device for mixing the composition is known.

However, the two-liquid mixing / discharging device of Patent Documents 1, 3, and 4 is preferable for mixing liquids or highly fluid contents, but is not suitable for mixing foamed contents. That is, the foamed contents are a collection of many small bubbles containing gas inside, and the bubbles are poor in fluidity and cannot be mixed evenly. Furthermore, since the active ingredient is in the liquid film on the foam surface, even if it is mixed in the foam state, there is little contact with the active ingredient and the mixing efficiency is poor. Further, when the foam is stirred by an external force or the like, the foam (liquid film) is crushed by the stirring operation, and the foam is liquefied and the quality of the foam is lowered and it tends to sag.
Furthermore, although the two-liquid mixing and discharging apparatus of Patent Document 6 has a small passage for mixing in a liquid state, each composition tends to remain in the passage after use by simply reducing the passage, and the composition is dried in the passage. And become clogged easily.
An object of the present invention is to provide a two-liquid mixing and discharging apparatus that mixes two kinds of compositions and discharges foamed contents.

And the foam suppression means is a throttle hole whose cross-sectional area is less than or equal to the sum of the cross-sectional areas of the two passages . Here, the cross-sectional area of the passage refers to the minimum cross-sectional area in the passage for supplying the first composition and the second composition to the two-liquid mixing and discharging device.
A second aspect of the two-liquid mixing and discharging apparatus of the present invention is a two-liquid mixing and discharging apparatus that discharges the foamed contents obtained by mixing the first composition and the second composition containing at least one liquefied gas, A first passage for supplying the first composition and a second passage for supplying the second composition; a mixing chamber communicating with the respective passages and mixing the first composition and the second composition in a liquid state; Foam suppression, which is provided between the mixing chamber and the discharge hole, communicating with the mixing chamber and discharging the foamed contents obtained by foaming the mixed liquid, and suppresses foaming of the composition in the mixing chamber. And the foam suppression means is a valve that opens when the pressure in the mixing chamber rises.
In such a two-liquid mixing / discharging device, it is preferable that the apparatus further includes a foaming chamber for foaming the mixed first composition and second composition between the foaming suppression unit and the discharge hole .

  In the two-liquid mixing / discharging device of the present invention, it is preferable that the first passage and the second passage are independently communicated with the mixing chamber. However, the first passage and the second passage may join and communicate with the mixing chamber.

The two-liquid mixing / discharging device 15 includes a cylindrical holding member 26 that holds two aerosol products 11, and a pusher that is disposed in the holding member so as to be vertically movable and is connected to the stems 17 of the two aerosol products. And a button 27. The discharge holes 15a of the two-liquid mixing / discharging device 15 are oriented in the vertical direction (surface direction in FIG. 2) with respect to the two aerosol products arranged side by side. Here, the direction of the discharge hole 15a is defined as the front direction.
The holding member 26 is formed in a cylindrical outer cylinder part 26a, two cylindrical holding parts 26b that are provided in the inside thereof, and hold the respective aerosol products 11, and an annular shape that connects the outer cylinder part 26a and the holding part 26b. The outer connecting portion 26c and the disc-shaped inner connecting portion 26d for connecting the holding portions 26b to each other. As shown in FIG. 1, a spout portion 3 of a push button 27 to be described later is provided in front of the outer cylinder portion 26a.
2 is formed, and a rear groove 26f for operating a push button 27 (to be described later) with a finger is formed behind the outer cylindrical portion 26a.

As shown in FIGS. 3A and 3B, the push button 27 includes a rectangular main body 31 and a cylindrical spout portion 32 attached to the front surface thereof. As shown in FIGS. 3c and 3d, the main body 31 includes a base material 33 and a cover 34 inserted on the base material.
As shown in FIGS. 3e and 3f, the base material 33 has a rectangular shape, a flange 33a that engages with the lower end of the cover 34 at the outer periphery of the lower end, and two parallel parallel penetrating holes on both sides of the base material. Two in-base material through paths 33b, two coaxial horizontal grooves 33c extending in the center direction from the upper end of the in-base material passage 33b, and two parallel parallel grooves extending forward from the tips of the two horizontal grooves 33c. A front and rear groove 33d is formed. That is, the front and rear grooves 33d are partitioned by the partition walls 33e so that the horizontal grooves 33c do not merge. The partition wall 33e is tapered on both sides so as to become a thin wall toward the front. Moreover, the lower end of the in-base material penetration path 33b is a stem engaging portion 33f that engages with the stem.
Returning to FIGS. 3 c and 3 d, the cover 34 is a cylindrical body having an upper base 34 a, and the upper base 34 a comes into contact with the upper surface of the base material 33 and covers the base material 33. In addition, a protrusion 34 b is formed at the top of the cover 34 and protruding forward at the height of the front and rear grooves 33 d of the base material 33. The projecting portion 34 b has a cylindrical shape and communicates with the inside and outside of the cover 34. And the space in this protrusion part 34b comprises the mixing chamber 36 mentioned later.
Thus, by comprising the main body 31 from the base material 33 and the cover 34, it can be easily disassembled and the contents can be easily cleaned and removed after use.

  With this configuration, when the base material 33 and the cover 34 are combined, the main body 31 is connected to the stem engaging portion 33f, the mixing chamber 36, the stem engaging portion 33f, and the mixing chamber 36. A body passage 35 is formed. The main body passage 35 includes a base material 33 and a cover 34, extends upward from the stem engaging portion 33 f (in-base material passage 33 b), and has two protrusions 34 b at the height of the protrusion 34 b of the cover 34. It is bent vertically toward the center surface of the aerosol product (the horizontal groove 33c and the upper bottom 34a of the cover 34), and further bent toward the protruding portion 34b just before the center surface (the front and rear groove 33d and the upper bottom 34a of the cover 34). ). That is, the two in-body passages 35 independently extend from the stem engaging portion 33 f and merge in the mixing chamber 36. A stirring member may be provided in the mixing chamber 36 so that the two compositions join together in a spiral shape.

As shown in FIGS. 3b to 3d, the cylindrical spout portion 32 has a main body engaging portion 37 in which the rear space receives the protruding portion 34b, and the front space has a foaming chamber 38 for foaming the mixed contents. It has become. The main body engaging portion 37 and the foaming chamber 38 communicate with each other through a throttle hole 39. The opening at the tip of the foaming chamber 38 is a discharge hole. The throttle hole 39 is configured to limit the delivery amount of the first composition A1 and the second composition A2 supplied from the aerosol product 11, and to control the composition so that it does not foam under pressure. Has been. In the present embodiment, the minimum cross-sectional area portion of the first composition A1 and the second composition A2 upstream from the mixing chamber is the stem hole 17b. Therefore, the cross-sectional area of the throttle hole 39 is less than or equal to the total cross-sectional area of the two stem holes 17b. However, when the minimum cross-sectional area portion of the first composition A1 and the second composition A2 is the main body passage 35 upstream from the mixing chamber, the cross-sectional area of the throttle hole 39 is equal to or less than the total cross-sectional area of the two main body passages. It becomes.
Since the push button 27 is configured as described above, the inside of the mixing chamber 36 is in a high pressure state as long as the first composition A1 and the second composition A2 from the aerosol product are continuously supplied to the push button 27. Thereby, the vaporization of the liquefied gas of the first composition A1 and / or the second composition A2 is prevented in the mixing chamber 36, and the first composition A1 and the second composition A2 are mixed in a liquid state. . Further, by making the spout portion 32 detachable, the contents in the passage after use can be easily cleaned and removed.

  The discharge product configured as described above discharges the foamed contents as follows. That is, when the push button 27 of the discharge product 10 is pressed downward, the stem 17 of the first aerosol product 11 a and the stem 17 of the second aerosol product respectively move downward, and the respective stem holes 17 b move from the stem rubber 18. Opened. Accordingly, the first composition A1 of the first aerosol product 11a and the second composition A2 of the second aerosol product 11b are introduced into the two-liquid mixing / discharging device 15. Thereby, the first composition A1 and the second composition A2 pass through the in-body passage 35 and reach the mixing chamber 36, respectively. As described above, as long as the aerosol valve of the aerosol product 11 is opened, the flow rate of the composition from the mixing chamber 36 is limited by the throttle hole 39, so that the inside of the mixing chamber 36 is in a high pressure state. Therefore, vaporization of the liquefied gas of the first composition A1 and the second composition A2 is prevented in the mixing chamber 36, and the first composition A1 and the second composition A2 are mixed while being in a liquid state. As a result, the first stock solution of the first composition A1 and the second stock solution of the second composition A2 can be mixed uniformly. The first composition A1 and the second composition A2 thus mixed are gradually sent out from the throttle hole 39 to the foaming chamber 38 in a liquid state (partially vaporized). In the foaming chamber 38, the liquefied gas of the mixture sent out in a liquid state is vaporized and discharged from the foaming chamber 38 as foamed contents. The foamed contents discharged in this manner are highly effective because the first composition A1 and the second composition A2 are uniformly mixed. Furthermore, since it is made to foam after mixing in the liquid state, the foam quality is also high.

4 to 7 shown below can be used in place of the push button 27 of the discharge product 11 of FIG.
The push button 40 in FIG. 4 is a pressure valve 41 in the throttle hole 39 of the push button 27 in FIG. 3. The other configuration is substantially the same as that of the push button 27. The pressure valve 41 is closed in a normal state, and is configured to open when a predetermined pressure is applied. Here, the predetermined pressure may be a pressure that is higher than the pressure when the two compositions flowing through the in-body passage 35 join in the mixing chamber 36. Such a pressure valve 41 can be configured by forming the spout portion 32 of an elastic body such as silicone rubber or synthetic rubber and making a cut in the partition between the main body engaging portion 37 and the foaming chamber 38.
Since it is configured in this manner, by performing a discharge operation, the first composition A1 and the second composition A2 are mixed in a liquid state in the mixing chamber 36, and the first composition A1 and the second composition are mixed. A2 can be mixed uniformly. Thereafter, when a predetermined pressure is reached, the pressure valve 41 opens and reaches the foaming chamber 38 as a uniform mixture, so that it can be discharged as a high-quality foam content. Further, when the discharge operation is stopped, the pressure in the mixing chamber decreases and the pressure valve closes, so that after-draw can be prevented.

The push button 45 in FIG. 5 also includes a rectangular body 46 and a cylindrical spout portion 47 attached to the front surface thereof. The spout part 47 is substantially the same as the spout part 32 of FIG.
As shown in FIG. 5 b, the main body 46 includes a base material 51, a cover 52 inserted on the base material, and a passage member 53 disposed between the base material 51 and the cover 52.

The cover 52 is a cylindrical body having an upper base 52a and has a shape that covers the base material. In addition, a protrusion 52b that protrudes forward at a height corresponding to the upper end of the in-base material passage 51b of the base material 51 is formed on the cover 52. The protrusion 52b has a cylindrical shape and communicates with the inside and outside of the cover 52.
As shown in FIGS. 5d and 5e, the passage member 53 connects the two leg portions 53a inserted into the in-base material through-passage 51b of the base material 51, and the upper surface of the base material 51. It consists of the flat part 53b to cover. Further, the flat portion 53b is configured to abut on the upper bottom 52a of the cover.
The leg portion 53a is formed with a through passage 53c extending vertically. The leg portion 53a is configured to be shorter than the in-base material through passage 52b. Two horizontal grooves 53d extending in the center direction from the upper end of the through-passage 53c are formed in the flat portion 53b, and communicated with the two horizontal grooves 53d at the center of the flat portion 53b and forward. A notch 53e extending toward the top is formed. In this device, by using the passage member 53, the through passage 53 constituting the in-body passage 55 is narrowed. Further, as shown in FIG. 5d, the horizontal groove 53d is formed to expand forward as it goes toward the center.

5a and 5b, since it is configured in this way, the main body 46 in which the base material 51, the cover 52, and the passage member 53 are combined has a stem formed by the base material through passage 51b and the leg portion 53a.

(Horizontal groove 53d and upper bottom 52a of cover 52). Since the horizontal groove 53d of the in-body passage 55 is configured to expand, and the mixing chamber 56 is configured to flow from the in-body passage 55 (horizontal groove 53d) as shown in FIG. The merging area between the main body passage 55 and the mixing chamber 56 is increased, and the two compositions are easily mixed uniformly in the mixing chamber 56.
In this embodiment, penetration passage 53c serves as the minimum cross-sectional area part of the passage of the 1st composition A1 and the 2nd composition A2. Therefore, the throttle hole 39 is smaller than these total cross-sectional areas. However, the stem hole may be configured as a minimum cross-sectional area portion. The mixed composition passes through the throttle hole 39 and foams in the foaming chamber 38 to become a high-quality foamed content. Furthermore, in this embodiment, by narrowing the passage using the passage member 53, the vaporization of the liquefied gas in the composition is suppressed in the passage 55 in the main body, and the two compositions are uniformly mixed in order to maintain the liquid state. it can. Although the passage is narrowed, the main body 46 can be disassembled, so that the contents in the passage after use can be easily cleaned and removed.

It consists of the flat part 65b to cover. The flat portion 65b has different left and right thicknesses so as to come into contact with the upper bottom 64a of the cover 64, and a step portion 65c extending in the front-rear direction is formed at the center. 6D and 6E, the left side of the flat portion 65b is thick and the right side is thin. The leg portion 65a is formed with a through passage 65d extending vertically. The leg portion 65a is also configured to be shorter than the in-base material through passage 51b. The flat portion 65b is formed with a horizontal groove 65e extending in the center direction from the upper end of one through passage 65d (left side in FIG. 6d), and in the center direction from the upper end of the other through passage 65d (right side in FIG. 6d). An extending horizontal notch 65f is formed, and a front and rear notch 65g is formed at the center so as to communicate with the horizontal groove 65e and the horizontal notch 65f and extend in the front-rear direction. This also uses the passage member 65 to narrow the through-passage 65d constituting the main body passage 69 described later. Further, as shown in FIG. 5d, the horizontal groove 65e and the horizontal notch 65f are formed so as to expand forward as they approach the center.
