Patent No. 6320796 JP 2019-182517 Publication Patent No. 6734699

The two-liquid discharge member disclosed in Patent Document 1 has the advantage that the outer discharge material blocks the odor of the inner discharge material, but since the inner discharge material is covered by the outer discharge material, it is difficult to confirm the discharge amount of the inner discharge material. In the two-liquid discharge nozzle of Patent Document 2, the two liquids are discharged in a striped pattern, so the discharge amount of the two liquids can be confirmed, but the odor of the contents cannot be blocked. The discharge tool of Patent Document 3 expands the surface area of the discharged material to exert the effect of the aromatic component. However, it does not discharge two types of contents.

SUMMARY OF THE INVENTION An object of the present invention is to provide a two-liquid discharge member and a two-liquid discharge product that can block the odor coming out of the inner discharge material and also allow easy confirmation of the discharge amount of the inner discharge material.

The two-liquid discharge member 40 of the present invention includes a first stem attachment part 81 attached to the first stem 24, a second stem attachment part 82 attached to the second stem 34, and a first discharge port at the axial tip. 71, an outer nozzle 140 that covers the inner nozzle 130 and forms a second discharge port 72 between the inner nozzle 130 and the inner nozzle 130 at its axial tip, and a A first discharge passage R1 that passes through and reaches the first discharge port 71, and a second discharge passage R2 that passes from the second stem mounting portion 82 and between the inner nozzle 130 and the outer nozzle 140 and reaches the second discharge port 72. , a plurality of V-shaped notches 41c are provided at the tip of the outer nozzle 140.

In such a two-liquid discharge member 40, it is preferable that the inner surface of the outer nozzle 140 is gradually tapered toward the tip.

The two-liquid discharge product 1 of the present invention includes a first container 20 having a first stem 24, a foamable first content C1 filled in the first container 20, and a second stem 34. A second container 30 filled with a second container 30, a second content C2 filled in the second container 30 that has a lower foaming property than the first content C1, or which does not foam, and a second content C2 filled in the second container 30. It is characterized in that it consists of any one of the two-liquid discharge members 40 attached thereto.

In the two-liquid discharge member of the present invention, the first stem attachment part is attached to the stem of the first container filled with foamable content, and the first stem attachment part is attached to the stem of the second container filled with low foaming or non-foaming content. It is used by attaching the second stem attachment part. As a result, the foamable first content is discharged from the inner first discharge port, and the low foaming or non-foaming second content is discharged from the outer second discharge port. At this time, since the first ejected material of the inner first content is covered by the second ejected material of the outer second content, the odor of the inner first ejected material is blocked. Furthermore, the foamed inner first ejected material expands, and the outer second ejected material bulges out from the V-shaped cut. As a result, a plurality of protrusions and grooves between them are formed on the surface of the second ejected material, and the first ejected material inside can be confirmed through the thin grooves.

If the inner surface of the outer nozzle is gradually tapered toward the tip, the progress of the ejected material is suppressed, so that the ejected material is strongly pushed out from the notch. Therefore, protrusions and grooves can be clearly formed on the surface of the discharged material.

In the two-liquid discharge product of the present invention, the inner first content foams and expands the outer second content, which has low foamability or does not foam, so that the thick and thin parts of the outer second discharge Easy to adjust the thickness.

The two-liquid discharge product 1 is a product in which the first container 20 is filled with the first content C1 and the second container 30 is filled with the second content C2. Each member will be explained in detail below.

The first container 20 on the right side of FIG. 1 includes a container body 21 having an opening 21a at the upper end, and a first valve 22 that closes the opening 21a of the container body 21. The first container 20 does not contain an inner container, and the first contents C1 are filled into the first container 20 directly or via a liner that protects the inner surface of the container.

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

The first valve 22 includes a bottomed cylindrical first stem 24 having a stem hole 24a on the side surface, a housing 25 that accommodates the first stem 24 so as to be movable up and down, and a housing 25 that allows the first stem 24 to always be kept upward (outside). The biasing elastic body (spring) 26 is approximately donut-shaped, and before the first stem 24 is pushed down (pushed in), the inner peripheral surface closes the stem hole 24a, and the first stem 24 is pushed down ( This is a so-called aerosol valve that includes a stem rubber 27 whose inner circumferential side bends to open the stem hole 24a when pushed (into the container), and a mounting cup 28 which fixes the housing 25 to the container body 21. Further, a gasket 25b is provided to seal between the outer peripheral surface of the housing 25, the upper end of the container body 21, and the inner surface of the mounting cup.

The mounting cup 28 is generally cup-shaped with a bottom at its upper end, and a portion of the first stem 24 projects upwardly from the bottom. Further, the mounting cup 28 is fitted onto the neck portion 21e of the container body 21 and caulked in the diameter reduction direction, and is fixed to the container body 21. The first container 20 configured as described above is in a closed state, and the first content C1 can be discharged only through the first valve 22.

The second container 30 shown on the left side of FIG. A second valve 32 that closes the opening 23a of the internal container 23 is provided. The inner container 23 is crushed by a pressurizing agent P filled in the space between the inner container and the container body 21, and is a bag made of synthetic resin or soft metal. The gasket 25b also seals between the inner container 23 and the housing 25 and between the inner container 23 and the container body 21. The second valve 32 does not have a dip tube 29, and is provided with an opening 25a on the side surface of the housing 25 for introducing the stock solution G of the second content C2 in the internal container 23 into the housing 25. Since the other parts are the same as those of the first valve 22, the same reference numerals are given and detailed explanations are omitted.

A shoulder cover 50 is attached to the first container 20 and the second container 30 to connect them. The shoulder cover 50 includes a fixed cylinder 50a that is externally fitted and fixed to the mounting cups 28 of the first container 20 and the second container 30, and a pair of guide cylinders 50c that protrude upward from the fixed cylinder 50a. The guide tube 50c is located on the outer periphery of the main body 60 of the discharge member 40, and guides the vertical movement of the discharge member 40.

The discharge member 40 connects the first stem 24 of the first valve 22 and the second stem 34 of the second valve 32. Therefore, by pushing down the discharge member 40, the first stem 24 of the first valve 22 and the second stem 34 of the second valve 32 can be pushed down (pushed) together, and the first stem 24 of the first valve 22 and the second stem 34 of the second valve 32 can be pushed down together. and can be opened together. Further, the first valve 22 and the second valve 32 can be kept open. Furthermore, by stopping the pressing down (releasing the hand), the first stem 24 of the first valve 22 and the second stem 34 of the second valve 32 return to their original positions before being pressed down together, and the first valve 22 and the second valve 32 can be closed together.

This discharge member 40 has a first connection port 61 connected to the first stem 24 of the first valve 22, a first discharge port 71 that discharges the first content C1, and a first discharge port 71 from the first valve 22. A first discharge passage R1 that communicates with the second content, a second connection port 62 that connects to the second stem 34 of the second valve 32, and a second connection port 62 that is arranged concentrically around the first discharge port 71 and that communicates with the second content in an annular manner. It includes a second discharge port 72 (see FIG. 4) that discharges C2, and a second discharge passage R2 that communicates from the second valve 32 to the second discharge port 72.

The first discharge passage R1 and the second discharge passage R2 do not intersect with each other and are independent from each other. Therefore, the first content C1 and the second content C2 do not mix within the discharge member 40.

The discharge member 40 having the above configuration includes a main body 60, a discharge nozzle 70, and a cutting nozzle 41, as shown in FIG. The incision nozzle 41 may be formed integrally with the discharge nozzle 70, particularly with an outer cylindrical portion 143 of an outer nozzle, which will be described later. The first discharge passage R1 passes through the main body 60 and the discharge nozzle 70, and finally communicates with the outside through the notch 41c of the notch nozzle 41 and the opening 41e at the tip. The second discharge passage R2 passes through the main body 60 and the discharge nozzle 70, and communicates with the interior of the cut nozzle 41.

The substantially cylindrical main body 60 on the side of the first container 20 is provided with a first stem connection part 81, and the first connection port 61 and a part of the first discharge passage R1 (on the main body 60 side) are provided inside the first stem connection part 81. It is provided. Specifically, a first connection port 61 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 61. A portion of the first discharge passage R1 extends upward from the first connection port 61 and then extends laterally. The main body 60 on the second container 30 side is provided with a second stem connection part 82 in the same way as described above, and the second connection port 62 and a part of the second discharge passage R2 (on the main body 60 side) are provided inside the second stem connection part 82. is provided.

The discharge nozzle 70 is a part that projects laterally from the main body 60, and has a cylindrical inner nozzle 130 and a thick cylindrical outer nozzle 140 surrounding the inner nozzle 130, as shown in FIG. The inner nozzle 130 and the outer nozzle 140 are arranged concentrically, and a first discharge port 71 on the inside and a second discharge port 72 on the outside are open at their tips. In other words, it can be said that the first discharge passage R1 and the second discharge passage R2 are each opened at the tip of the discharge nozzle 70.

As shown in FIG. 2, a substantially cylindrical cutting nozzle 41 is fitted at the tip of the outer nozzle 140. As shown in FIG. As shown in FIGS. 3A to 3C, the cutting nozzle 41 includes a cylindrical base 41a that fits into the tip of the outer nozzle 140, and a split end portion 41b extending forward from the base 41a. The diameter of the split end portion 41b gradually decreases toward the tip, and is further curved to convex outward, so that it has the shape of a cannonball or half of a rugby ball. As shown in FIG. 3A, the tip split portion 41b has a V-shaped cut 41c that gradually widens toward the tip. The split end portion 41b is divided into six nozzle pieces 41d by the cuts 41c.

The width of each nozzle piece 41d gradually becomes narrower toward the tip. In this embodiment, the left and right edges of each nozzle piece 41d are approximately arcuate, and as shown in FIG. 3C, the thickness gradually decreases toward the tip. Further, the tip of the nozzle piece 41d when viewed from the outside is sharp so as to have a substantially V-shape.

The first content C1 filled in the first container 20 includes a first agent (undiluted solution) of a two-component reaction type that exhibits its effect by reacting two types of contents, and a first agent (undiluted solution) that is a two-component reaction type that exhibits an effect by reacting two types of contents. It contains a foaming agent for pressurizing and foaming, and the foaming agent is emulsified in a stock solution, or emulsified by shaking before discharge. The dip tube 29 is open within the liquid phase of the first content C1, and mainly the liquid phase is discharged. The contents of the two-component reactive type include, for example, a two-component warming preparation, a two-component exothermic preparation, a two-component cooling preparation, a two-component gelling agent, a two-component film forming agent, a two-component adhesive, Examples include two-component hair dyes and two-component perm agents. In particular, in the case of a two-component hair dye that exhibits its effect through oxidation, by containing the oxidation dye in the first content C1, the part that is thickly covered by the second content C2 will not change color and will be thinly covered. The part that is covered starts to develop color and changes in color, making it easy to confirm through the second content C2.

The blowing agent also serves as a pressurizing agent, and is a liquefied gas, a compressed gas, or a mixed gas thereof. Examples of the liquefied gas include normal butane, isobutane, propane, and liquefied petroleum gases that are mixtures thereof, dimethyl ether, hydrofluoroolefins, and mixtures thereof. Examples of the compressed gas include nitrogen, air, oxygen, hydrogen, carbon dioxide, nitrous oxide, etc., and are filled so that the pressure at 25° C. is 0.2 to less than 1.0 MPa.

The second content C2 filled in the second container 30 is between the second agent (undiluted solution) G of the two-liquid reaction type content filled in the inner container 23 and the second container 30 and the inner container 23. , and a pressurizing agent P for pressurizing the second agent (undiluted solution) G through the internal container 23 and discharging it to the outside. Hereinafter, the second agent (undiluted solution) may be simply referred to as the second content C2. Furthermore, the contents that are discharged to the outside and have a foam-like or cream-like appearance are also referred to as contents 1 and 2 as they are. As the pressurizing agent P, it is preferable to fill it with compressed gas. In addition, a fine foaming agent having a boiling point of 15 to 40°C, such as isopentane or trans-1-chloro-3,3,3-trifluoropropene, may be added to the second part (stock solution) G to emulsify it. In this case, the second agent foams slowly and small after being discharged.

In addition, the undiluted solution of the first content C1 and the undiluted solution of the second content C2 may be contents that exhibit at least two effects other than the two-component reaction type, such as a sunscreen, an antiperspirant, and a sunscreen. and pest repellents, hand sanitizers and moisturizers, foundations and antiperspirants, cosmetic coats and antiperspirants, etc. Moreover, the first content C1 is discharged from the discharge port (see reference numeral 71 in FIG. 4) inside the double nozzle, and is foamed externally to form a foam shape. The second content C2 is discharged in the form of a gel, cream, or low-foaming foam from the outer discharge port (numeral 72 in FIG. 4) of the double nozzle. None of the contents are sprayed, and the second content C2 is discharged in the form of a gel or cream, or even in a slightly foamed state, and the first content C1 is foamed and foamed, and the second content C2 The object C2, including the first content C1, passes through the incision nozzle 41 and is discharged to the outside. By making the second content C2 into a cream, gel, or low-foaming foam, and making the first content C1 into a foam, the foam injected into the cream or gel after discharging increases and the incision nozzle 41 When passing through the second content C2, a difference in thickness is likely to be formed in the second content C2.

In addition, to give an example of the first content C1, by using a fragrance having a different scent from the second content C2 in the first content C1, the first content C1 is injected into the second content C2. When C1 comes into contact with the outside air, it can change its odor. Furthermore, if the first content C1 contains a component that emits a pungent odor, such as ammonia, the pungent odor can be alleviated by wrapping it in the second content C2. Furthermore, if the first content C1 contains a component that decomposes and generates gas, such as hydrogen peroxide, scattering during discharge can be suppressed by injecting it into the second content C2.

Returning to FIG. 1, in this two-liquid discharge product 1, 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 the shoulder cover 50, which includes a connecting portion 50b that connects the fixed cylinders 50a in the lateral direction, and their mutual positional relationship is fixed. Further, a cover member 90 is attached to the shoulder cover 50. This cover member 90 is provided with a surrounding part 90a that protrudes above the discharge nozzle 70 and surrounds the discharge nozzle 70 from the side, and functions as a cap to prevent the discharge nozzle 70 from being pushed in unintentionally. This helps prevent the nozzle 70 from tilting when pushed.

Both the first valve 22 and the second valve 32 are continuous valves, with the first valve 22 having a dip tube 29 and the second valve 32 not having a dip tube.

In the discharge member 40, the main body 60 is divided into two parts, one of which is connected to the first valve 22 and the other to the second valve 32.

The discharge nozzle 70 connects the main body 60 divided into two parts. This discharge nozzle 70 includes a first connecting portion 100 extending from the main body 60 on the first valve 22 side, a second connecting portion 110 extending from the main body 60 on the second valve 32 side, and a first connecting portion 100 and a nozzle member 120 connected to the second connecting portion 110.

As shown in FIGS. 2 and 4, the first connecting portion 100 and the second connecting portion 110 include a substantially cylindrical base 101 and a substantially circular shape protruding in a direction (lateral direction) substantially perpendicular to the axial direction of the base 101. A columnar nozzle connection part 102 is provided. The nozzle connection part 102 is a part inserted into and connected to the nozzle member 120, as shown in FIG. Inside the first connecting portion 100, there is provided a connecting portion passage J1 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 internal passage J1 extends upward along the axial direction of the base portion 101, and then extends laterally along the axial direction of the nozzle connecting portion 102. The upstream side of this passage J1 within the connecting portion communicates with a passage within the main body 60.

As shown in FIG. 4, the nozzle member 120 is a so-called double nozzle, including an inner nozzle 130 having a first discharge port 71 at the axial tip, and a second discharge port 71 that covers the inner nozzle 130 and has a first discharge port 71 in between. An outer nozzle 140 forming two discharge ports 72 is provided. The inner nozzle 130 and the outer nozzle 140 are arranged concentrically.

The inner nozzle 130 includes a cylindrical inner cylinder part 131 and a flange part 132 provided at the rear end of the inner cylinder part 131. Inside the inner cylinder portion 131, an inner nozzle passage N1 is provided along the axial direction. The opening at the tip of the inner nozzle passage N1 is the first discharge port 71. The rear end of the inner nozzle passage N1 is closed. An outlet hole 131a is provided on the side surface of the inner cylinder part 131, which communicates the outside of the inner cylinder part 131 with the inner nozzle passage N1.

The outer nozzle 140 includes a first insertion part 141 into which the first connection part 100 of the inner passage is inserted, a second insertion part 142 into which the second connection part 110 of the outer passage is inserted, and a cylindrical outer cylinder part 143. We are prepared.

The outer cylindrical portion 143 has a circular cross-sectional shape on both the outer and inner peripheries. However, the shape is not limited to a circle, and may be a polygon. Preferably, the shape is rotationally symmetrical, such as a regular polygon. By housing the inner nozzle 130 in the outer cylinder part 143, an outer nozzle internal passage N2 is formed between the inner nozzle 130 and the outer cylinder part 143.

In this discharge member 40, the first discharge passage R1 passes through the first valve 22, the main body 60, the first connecting portion 100, and the inner nozzle passage N1 to reach the first discharge port 71, and the second discharge passage R2 It reaches the second discharge port 72 through the second valve 32, the main body 60, the second connecting portion 110, and the outer nozzle internal passage N2. The first discharge passage R1 and the second discharge passage R2 are independent from each other, and the contents C1 and C2 do not mix with each other within the two-liquid discharge member 40.

To use the two-liquid discharge product 10 described above, the upper surface of the nozzle member 70 is pushed in with the tip of the nozzle member 70 facing the palm, brush, plate, etc. that will receive the discharged material. Thereby, the second content C2 passes through the outer nozzle internal passage N2 and comes out from the second discharge port 72. On the other hand, the first content C1 passes through the inner nozzle passage N1, comes out from the first discharge port 71, and enters the second content C2. Alternatively, the second content C2 is discharged in a cylindrical shape so as to cover the first content C1 (see FIG. 5B).

Next, the inner first content C1 foams and swells, and moves forward while pushing and expanding the outer second content C2. Thereby, the second content C2 passes through the notch 41c of the notch nozzle 41 and spreads outward, forming a protrusion 42 and extending in a striped manner as shown in FIG. 5B (see FIG. 5C). A groove 43 remains between the protrusions 42. As a result, as shown in FIG. 5B, a double ejected material T is obtained in which a foamy first content C1 is covered with a layer of creamy second content C2. The outer layer of the second content C2 has a gear-like or petal-like shape in which protrusions 42 and grooves 43 are alternately formed.

Since this discharged material covers the first content C1 with the second content C2, even if the first content contains a volatile component that generates an odor, it is blocked by the layer of the second content C2. Discomfort is suppressed. Furthermore, since the layer of the second contents C2 on the outside is thinner at the groove 43, the first contents C1 inside can be visually recognized from the outside. In this case, the inner first content C1 tends to become white due to foaming, but it becomes easier to visually recognize it by providing a thinly covered portion with the outer second content C2. Note that if the entire second content C2 is made thinner, the color of the inner first content C1 appears over the whole, making it difficult to distinguish the outline of the inner first content C1. Since this discharge member 70 has the protrusions and grooves as described above, the inner first content C1 appears in a striped manner, making it easy to see the outline and the position of the tip of the inner first content C1. . In particular, when a two-component discharge product is used as a two-component hair dye, the inner first content C1 is the first ingredient containing an oxidized dye, and the outer second content C2 is an oxidized dye such as hydrogen peroxide. By using the second agent containing the agent, it becomes easier to visually confirm the first agent that is oxidized and begins to develop color in a thin portion of the second content C2.

Although the embodiments of this invention have been described above, this invention is not limited to the above embodiments, and can be implemented with various changes within the scope of this invention. For example, although the above-mentioned cutting nozzle 41 has the split end portion 41b gradually tapered toward the tip, it may extend with the same diameter.

Further, the second container 30 can be an external container (container main body 21) that does not contain a flexible inner container, and the first container 20 can be used to prevent corrosion caused by the first contents C1. Additionally, an inner container made of synthetic resin having a shape along the inner surface of the outer container can be accommodated. Further, each of the two-liquid discharge containers 10 and 10A uses two containers (the first container 20 and the second container 30), but one container having two valves may also be used. In this case, two chambers or inner bags are provided in one container to prevent the contents from mixing with each other, and to allow different contents to be discharged from the two valves.
