The embodiment described below is an example of the configuration of the present invention, and the present invention is not limited to the following embodiment. Various modifications may be made as long as the effects of the present invention are achieved.

  The cap mounted on the container used in the present invention is a so-called GIZMO cap disclosed in Patent Documents 1 to 3. The GIZMO cap has a tank in which a secondary liquid and a gas for injecting the secondary liquid are placed, a nozzle for injecting the secondary liquid, and a valve that partitions the tank and the nozzle. Here, in the container used in the present invention, GIZMO is deformed so that the tip of the nozzle is positioned above the liquid surface of the main liquid. And in the beverage product with a secondary liquid mixing function in which the GIZMO cap is attached to the mouth of the container filled with the main liquid, the valve is opened with the cap opening operation, and the secondary liquid is injected by the injection gas. It is injected toward the main liquid. In the present invention, it is possible to use the cap disclosed in Patent Documents 1 to 3 or a modified form of the cap, but as an example, the configuration shown in FIGS. The GIZMO cap will be described using the first form of the container) and the form shown in FIGS. 5a to 5e of the Patent Document 2 (hereinafter referred to as the second form of the container), and also refer to the modified form. .

  First, the plastic cap which concerns on the 1st form of a container is demonstrated with reference to FIG. FIG. 1 is a cross-sectional view for explaining the structure of a plastic cap used in the first form of the container. (A) is an unopened state, and (b) is a state immediately before the valve is opened during the opening of the cap. The state (c) shows a state in which the valve is opened during the opening of the cap. As shown in FIG. 1 (a), the plastic cap 20 has a housing 1 having an upper lip 2. Extending from the bottom of the housing 1 is a nozzle connector 5. The nozzle length can be adjusted by attaching a nozzle (not shown) to the nozzle connector 5. The housing 1 has a rupture member 6 that extends upward and ends at a spike 7. In the present embodiment, it is preferable that the nozzle is shortened so that the tip of the nozzle is positioned above the liquid surface of the main liquid, and a form in which the tip of the nozzle ends at the bottom of the housing 1 is more preferable. The nozzle connector 5 may be used as a nozzle without mounting the nozzle on the nozzle connector 5. When the nozzle is long, it is easy to give the user a sense of incongruity in appearance.

  On the side wall of the housing 1 is a ridge 3 that extends to surround the interior of the housing 1.

  The tank 11 has a lower open end sealed by a sealing gasket 12 and a rupturable membrane 13. The sealing gasket 12 is annular and has a central opening 14. The tank 11 also has an O-ring seal 8 surrounding it in a recess 4 surrounding the periphery of the tank 11.

  In use, the tank 11 is filled with a secondary liquid 15 and a pressurized propellant gas 16 by conventional techniques used to fill pressurized dispenser packs commonly known as aerosol containers. The tank 11 is inserted into the housing 1 and pushed into the housing 1 until the O-ring 8 meshes with the ridge 3. The position is shown in FIG. In this position, the membrane 13 is above the rupture member 6 and the spike 7.

  The housing 1 and the tank 11 are inserted into the opening (not shown) of the container, the housing 1 is in close contact with the opening, and the tip of the nozzle (not shown) attached to the nozzle connector 5 contacts the main liquid in the container 50. Although it may be, it is more preferable that it is directed in the direction without contact. The housing 1 is supported in the opening by an upper lip 2 that rests on top of the container opening. It is more preferable that the housing 1 is fixed to the inner surface side of the top surface of the lid that is threaded.

  When the lid is moved to the opening side of the container, the tank 11 moves downward and moves to the position shown in FIG. At this time, the spike 7 ruptures the rupturable membrane 13 and the rupture member 6 reaches the opening 14 in the gasket 12. In this position, the secondary liquid 15 and the injection gas 16 are prevented from escaping from the tank 11 by the gasket 12 and the rupture member 6 that are sealed together to prevent the secondary liquid 15 and the injection gas 16 from being released from the tank 11. It is.

  The tank 11 remains in the position shown in FIG. 1 (b) until the user opens the lid from the container. When the lid is released from the container, the tank 11 moves to the position shown in FIG. In this position, the gasket 12 is no longer sealed from the rupture member 6, and the secondary liquid 15 passes alongside the rupture member 6 together with the injection gas 16 by the injection gas 16 and into the direction of the arrow 17 and into the nozzle connector 5. Extruded. At that time, the secondary liquid 15 is discharged through the nozzle connector 5 toward the main liquid in the container. That is, the rupturable membrane 13 serves as a valve that partitions the tank 11 and the nozzle (in the case of the present embodiment, the nozzle connecting machine 5), and the valve (ruptureable membrane) is accompanied by the opening operation of the plastic cap. 13) is in the open state, and the secondary liquid 15 is jetted by the jet gas 16 toward the main liquid.

  When the lid is removed, the tank 11 is fixed to the inner surface of the top surface of the lid, and the housing 1 is fixed to the tank 11 by the non-return locking tab 19. Removed from. Before the housing 1 and the tank 11 are removed from the container, the secondary liquid 15 is jetted toward the main liquid from the nozzle connector 5 and further from the nozzle when the nozzle is fixed. The secondary liquid is prevented from rising between the housing 1 and the tank 11 by the O-ring 8.

  The upward movement of the tank 11 from the position shown in FIG. 1 (b) to the position shown in FIG. 1 (c) is supported by a spring located between the gasket 12 and the bottom of the housing 1. Can do. The tank 11 is shown in FIG. 1 (c) by using a spring or by the pressure in the container 11 that reacts against the rupture member 6 to push the tank 11 into the position shown in FIG. 1 (c). You may move to a position.

  Next, the plastic cap which concerns on the 2nd form of a container is demonstrated with reference to FIG. FIG. 2 is a cross-sectional view for explaining the structure of a plastic cap used in the second form of the container. FIG. 2 (a) shows a container 150 having an insertion member 100 that is secured within the neck 160 of the container. The screw lid 152 is separated before the container 150 is sealed. The lid 152 has an internal groove that mates with the external groove of the container neck 160. The lid forms an integrally formed tank 111, and the tank 111 has a cylindrical shape that is closed at the upper end by a convex portion on the top surface of the lid 152 and opened at the lower end.

  Insert member 100 is secured within neck 160 of container 150 in any suitable manner. The insertion member 100 consists of a substantially cylindrical housing 101 that has several legs 190 that open at the upper end and project from the lower end. The housing is provided with a locking member that meshes with the inside of the neck 160 of the container so that it cannot be easily removed. The upper end of the housing has a lip 102 that is fitted to mate with a recess 103 in the neck 160 of the container to prevent the insertion member 100 from being pushed down into the neck 160.

  The foot 190 is connected at its lower end to a hollow spike member 104 having a small diameter bore portion at its upper end and a large diameter bore portion at its lower end. Between the legs 190, there is an opening through which liquid can pass from between the spike member 104 and the side of the container when the liquid is poured from the container. The number of legs and the number of openings between them may be two, three, four or suitably more.

  The wall of the small diameter bore is provided with several radial passages 108 leading to the hollow interior of the spike 104 and the interior of the housing 101. Extending from the bottom of the hollow rupturable member 104 is a nozzle 130 secured to the rupturable member 104. In the present embodiment, it is preferable that the nozzle is shortened so that the tip of the nozzle is positioned above the liquid surface of the main liquid, and a form in which the tip of the nozzle ends at the bottom of the housing 1 is more preferable. When the nozzle is long, it is easy to give the user a sense of incongruity in appearance.

  In use, the tank 111 is filled with a secondary liquid 115 and a propellant gas 116 pressurized according to the prior art used to fill a pressurized dispenser pack, commonly known as an aerosol container. In the cited document 2, the secondary liquid is represented as the liquid 131 put in the nozzle 130. However, in this embodiment, the liquid 115 is put in the tank 111 without containing the liquid 131. Is preferably used as a secondary liquid.

  FIG. 2B shows the lid 152 while being screwed onto the neck 160. When the lid 152 is screwed and installed deeper into the container 150, the tank 111 is moved downward and the spike 104 enters the space formed by the inner cylindrical wall 172 of the ferrule 170.

  When the lid 152 is fully screwed onto the container 150, the tank 111 moves to the position shown in FIG. 2 (c), and the sealing member 154 inside the lid 152 is tight against the upper portion 156 of the container neck 160. Seal. When this happens, the spike 104 ruptures the rupturable membrane 180 and the hollow spike reaches the tank 111. In this position, the secondary liquid 115 and the injection gas 116 escape from the tank 111 by the ferrule 170 and the spike member 104 that seal against each other in order to prevent the secondary liquid 115 and the injection gas 116 from being released from the tank 111. It is prevented.

  The tank 111 remains in the position shown in FIG. 2C until the user opens the lid 152 from the container 150. When this happens, the tank 111 moves to the position shown in FIG. The secondary liquid 115 and the injection gas 116 are pushed out to the nozzle 130 through the radial passage 108 between the spike member 104 and the ferrule 170 in the directions of arrows 184, 185 and 186. It is discharged into the main liquid that has entered the container 150. That is, the ruptureable membrane 180 serves as a valve that partitions the tank 111 and the nozzle 130, and the valve (ruptureable membrane 180) is opened as the plastic cap is opened, and the secondary liquid is opened. 115 is injected toward the main liquid by the injection gas 116.

  Upon removal of the lid 152, the tank 111 and the ruptured ferrule 170 are removed together from the container 150, leaving the insertion member 100 and nozzle 130 in the container, as shown in FIG. 2 (e). The insertion member 100 does not prevent the liquid from being poured into the container 150, and the liquid can flow between the support legs 190 of the insertion member 100.

  As a modified example of the second form of the container, FIG. 3 shows a modified example of the structure of the plastic cap used in the second form of the container (the form in which there is no nozzle and the secondary liquid is jetted toward the liquid surface of the main liquid). It is sectional drawing for demonstrating, (a) is an unopened state, (b) is a state just before a valve will be in an open state in the middle of opening of a cap, (c) is a valve in an open state in the middle of opening of a cap. (D) shows a state in which the secondary liquid is injected, and (e) shows a state in which the lid is removed. Although it does not give the user a sense of incongruity in appearance, forming is easier because the secondary liquid spreads during injection than when a nozzle is used.

  In the first form of the container or the second form of the container (including modified examples), when the container body is filled with a beverage that does not contain carbon dioxide gas as the main liquid, the mixing of the secondary liquid can be done by placing the nozzle tip in the main liquid. It can be easily adjusted by dipping and adjusting the length of the nozzle. That is, the convection condition of the secondary liquid in the main liquid may be made suitable. However, when the container body is filled with a beverage containing carbon dioxide as the main liquid, it cannot be handled only by adjusting the convection condition of the secondary liquid in the main liquid. 4A and 4B are diagrams for explaining a state when the sub-liquid is injected toward the main liquid. FIG. 4A is a state immediately after the sub-liquid is injected into the main liquid, and FIG. Convection in the container, (c) shows that the secondary liquid does not convect well due to forming. For example, when the auxiliary liquid is injected toward the main liquid, as shown in FIG. 4A, an extremely reduced pressure point (injection flow) is locally generated at the boundary between the injection flow (sub-liquid flow 201) and the main liquid. Side part) 200 occurs. When the secondary liquid is injected, the secondary liquid is pushed out together with the injection gas and is released from the high-pressure space to the low-pressure space, so that it immediately boils immediately after the injection and bubbles are generated. At the same time, the carbon dioxide in the main liquid is also induced by the stimulation and vaporizes. However, if the forming is suppressed as shown in FIG. 4B, the flow 201 of the secondary liquid proceeds toward the bottom of the main liquid. However, when the forming is not suppressed, as shown in FIG. 4C, an upward flow is generated by the forming 202, so that the secondary liquid is raised without reaching the bottom of the main liquid. The liquid cannot be settled and a secondary liquid pool is generated in the upper part of the main liquid. When the degree of forming is intense, further blow-off occurs. The difference in height between the main liquid level and the top surface of the container mouth (headspace height) is usually about 1 to 6 cm.

  Therefore, when the container main body is filled with a beverage containing carbon dioxide gas as the main liquid, it is necessary to prevent the secondary liquid from being pooled and to prevent spilling. For this purpose, it becomes a problem to suppress forming. In order to suppress the forming, the kinetic energy given to the main liquid by the secondary liquid must be suppressed. On the other hand, if this kinetic energy of the secondary liquid is lowered too much, there arises a problem that the secondary liquid does not mix with the main liquid. The kinetic energy of the secondary liquid is determined by the injection speed of the secondary liquid and the amount (mass) of the secondary liquid. The injection speed of the secondary liquid is further influenced by the pressure of the injection gas and the gas volume of the injection gas. If the pressure of the injection gas is high and the gas volume of the injection gas is large, the injection speed of the secondary liquid is Get faster.

  In order to suppress the forming, among the factors affecting the kinetic energy of the secondary liquid, for example, there is a method of suppressing the injection speed of the secondary liquid. Specifically, (1) the injection speed is reduced by lowering the pressure of the injection gas and reducing the gas volume of the injection gas, and (2) when the secondary liquid is injected by reducing the nozzle diameter. Increase viscosity resistance and reduce injection speed. (3) Increase viscosity resistance of secondary liquid by increasing viscosity of secondary liquid and decrease injection speed. (4) Reduce nozzle length. There are four methods: lengthening, increasing the viscous resistance during the injection of the secondary liquid, decreasing the injection speed, or bringing the tip of the nozzle into contact with the base. However, the method (1) does not provide a sufficient effect for suppressing forming, and further pressure drop tends to cause injection failure. In the method (2), the inner diameter of the nozzle is usually 0.50 to 0.90 mm (for example, 0.75 mm), and it has been found that forming the nozzle smaller than less than 0.5 mm has an effect of suppressing forming. There is a demerit that nozzles of less than 0.5 mm cannot be stably produced. Further, the method (4) is effective, but it is easy to give the user a sense of incongruity in appearance, and it is desirable that the nozzle is housed in the housing so as not to stand out in appearance. It has been found that the method (3) suppresses forming in a specific viscosity range and can eliminate mixing failure.

  Therefore, in this embodiment, the tip of the nozzle is separated from the liquid surface of the main liquid, and preferably a cap with a tank in which the nozzle is housed in the housing is used, and the sub-liquid injection speed is suppressed as means for suppressing the sub-liquid injection speed. A method of keeping the viscosity within a specific range was adopted.

(First form of the product: When the carbon dioxide volume of the main liquid is 1 to 3 GV)
In the beverage product with a secondary liquid mixing function according to the present embodiment, the main liquid filled as the contents of the container is a beverage containing carbonic acid having a carbon dioxide gas volume of 1 to 3 GV and a sugar concentration of 0 to 20 w / w%. . Here, the beverage containing carbonic acid is not particularly limited as long as it is a beverage containing carbonic acid, and examples thereof include carbonated beverages, wort, sparkling liquor, chuhai, and cocktails. When the carbon dioxide volume is 1 to 2 GV, it belongs to a so-called fine carbonated product, and when the carbon dioxide volume is 2 to 3 GV, it belongs to a normal product. In the case of carbonated drinks such as juice, sugars derived from sweeteners are contained, sugars derived from fermentation raw materials are contained in barley and happoshu, and sugars derived from fruit juice etc. are contained in Chuhai and cocktails. All of them contain 0 to 20 w / w% of sugar as the sugar concentration. The sugar concentration affects the viscosity of the main liquid, and the lower the sugar concentration (the lower the viscosity), the more difficult it is to suppress forming.

The secondary liquid is, for example, an extract such as a fragrance, a coloring agent for adding color, and an umami component, and enhances the main liquid when mixed with the main liquid. Moreover, an entertainment effect is easy to be acquired by mixing with the main liquid at the time of opening. Since it is separated from the main liquid until just before serving for beverages, it is easy to preserve. In the present embodiment, the secondary liquid preferably has a viscosity of 5 to 41 mPa · s. In order to control the injection speed when being pushed out of the tank by the injection gas, viscosity adjustment is performed. If the viscosity is increased, the injection speed can be decreased, and if the viscosity is decreased, the injection speed can be increased. Specifically, the sugar is added to the secondary liquid to increase the viscosity. For example, the viscosity can be adjusted to 5 to 41 mPa · s by adjusting the density of the secondary liquid to 1.14 to 1.26 g / cm ³ . As saccharides, monosaccharides, disaccharides, oligosaccharides (trimers or more), polysaccharides, or combinations thereof can be used, and they are properly used according to various properties such as compatibility with the main liquid and specifications of beverage products. . If the density of the secondary liquid exceeds 1.26 g / cm ³ , it tends to settle at the bottom of the main liquid.

In this embodiment, by setting the kinetic energy (Econq) of the secondary liquid to be in the range of 0.10 to 0.27 J, forming is suppressed and it is difficult to cause the secondary liquid to accumulate. If Econq) is less than 0.10 J, a secondary liquid pool tends to occur, and if it exceeds 0.27 J, forming tends to occur. The kinetic energy (Econq) is the density of the secondary liquid ρ (g / cm ³ ), the volume of the secondary liquid in the tank vt (cm ³ ), and the initial injection speed of the secondary liquid injected from the nozzle is V1 (m / cm ³ ). When s), the calculation is performed using Equation 1. The injection initial speed V1 is measured using, for example, a high-speed camera.
(Equation 1) Econq = 1/2 · vt · ρ · (3/4 · V1) ²

Equation 1 was obtained as follows. First, the condition was set so that the volume of the secondary liquid was half the tank capacity.
When the initial pressure in the tank before injection is P1, and the tank pressure at the moment of completion of injection is P2, the relationship of Equation 2 is established.
(Expression 2) P2 = 1/2 · P1
The initial injection speed is V1, the injection speed at the end of injection is V2, and the average injection speed during the injection process is Va.
(Expression 3) V2 = 1/2 · V1
(Expression 4) Va = (V1 + V2) / 2 = (V1 + 1/2 · V1) / 2 = 3/4 · V1
When the volume of the secondary liquid in the tank is vt and the density is ρ, the kinetic energy (Econq) of the secondary liquid is (Equation 5) Econq = 1/2 · vt · (Va) ² = 1/2 · vt · ρ · ( 3/4 · V1) ²

(The second form of the product: When the carbon dioxide volume of the main liquid exceeds 3 GV and 4 GV or less)
In the beverage product with a secondary liquid mixing function according to the present embodiment, the main liquid filled as the contents of the container contains carbon dioxide having a carbon dioxide gas volume exceeding 3 GV and 4 GV or less and a sugar concentration of 0 to 20 w / w%. It is a beverage. Here, the beverage containing carbonic acid is the same as in the case of the first form of the product. However, when the carbon dioxide volume exceeds 3 GV and is 4 GV or less, it belongs to a so-called strong carbonated product. Also, as in the case of the first form of the product, 0-20 w / w% of saccharide is included as the sugar concentration, the sugar concentration affects the viscosity of the main liquid, and the sugar concentration is lower (low viscosity) However, it is difficult to suppress forming. A product with a high amount of carbonic acid and a low sugar concentration is most likely to form, so the injection conditions for the secondary liquid are also strict.

The secondary liquid is the same as in the case of the first form of the product, but the viscosity is set to 20 to 41 mPa · s in order to further suppress the forming. In order to obtain such viscosity, specifically, the viscosity can be adjusted to 20 to 41 mPa · s by adjusting the density of the secondary liquid to 1.22 to 1.26 g / cm ³ . As the saccharides, monosaccharides, disaccharides, oligosaccharides (trimers or more), polysaccharides, or combinations thereof can be used, and they are properly used according to various properties such as compatibility with the main liquid and specifications of beverage products. . If the density of the secondary liquid exceeds 1.26 g / cm ³ , it tends to settle at the bottom of the main liquid.

  In this embodiment, by setting the kinetic energy (Econq) of the secondary liquid to be in the range of 0.10 to 0.19 J, forming is suppressed and the liquid pool of the secondary liquid is hardly generated. If Econq) is less than 0.10 J, a secondary liquid pool tends to occur, and if it exceeds 0.19 J, forming tends to occur. Kinetic energy (Econq) is calculated by Equation 1 as in the case of the first form of the product.

Three levels, the gas for injection was nitrogen gas. Moreover, the injection initial velocity V1 of the secondary liquid was measured using a high-speed video camera (FASTCAM ultra 1024 manufactured by PHOTRON). Furthermore, the volume of the container body is 265 cm ³ , the volume of the main liquid filled in it is 250 cm ³ , the difference in height between the main liquid surface and the top of the container mouth (head space height) is 5 cm, the height of the container body The thickness was set to 170 mm.

Table 1 summarizes the results of the kinetic energy of the secondary liquid, the presence or absence of spilling due to forming, and the situation of the secondary liquid pool. In Table 1, the following criteria were used for forming and evaluation of the liquid pool.
○: Blowing does not occur and there is no liquid pool of secondary liquid.
× 1: Blowing occurred. × 2: Blowing did not occur, but the secondary liquid accumulated at the bottom of the main liquid.

  As can be seen from Table 1, when the main liquid is a beverage containing carbonic acid having a carbon dioxide volume of 1 to 3 GV and a sugar concentration of 0 to 20 w / w%, that is, a beverage of fine carbonate to ordinary carbonate. In this case, when the viscosity of the secondary liquid is 5 to 41 mPa · s and the kinetic energy Econq in the injection of the secondary liquid is within the range of 0.10 to 0.27 J, the secondary liquid does not spill and the secondary liquid pools. Absent. Under the condition that the carbon dioxide gas volume is 1 GV, even when the kinetic energy Econq in the injection of the secondary liquid exceeds 0.27 J and is 0.36 J or less, similarly, the blow-off does not occur, and the secondary liquid pools. However, the condition that the carbon dioxide volume of the main liquid can be commonly used in the whole range of 1 to 3 GV is when the above range is satisfied.

  As can be seen from Table 1, when the main liquid is a beverage containing carbon dioxide with a carbon dioxide volume volume exceeding 3 GV and 4 GV or less and a sugar concentration of 0 to 20 w / w%, that is, a beverage with strong carbon dioxide. When the viscosity of the secondary liquid is 20 to 41 mPa · s and the kinetic energy Econq in the injection of the secondary liquid is in the range of 0.10 to 0.19 J, the secondary liquid does not spill and the secondary liquid does not accumulate. . In the case of a strong carbonated beverage, the conditions are more stringent, but when the above conditions are satisfied, the spillage does not occur and no secondary liquid pool is produced. This condition satisfies the preferable condition even in the case of a beverage containing carbonic acid having a carbon dioxide volume of 1 to 3 GV and a sugar concentration of 0 to 20 w / w%, and the viscosity of the secondary liquid is 20 When the kinetic energy Econq in the injection of the secondary liquid is in the range of 0.10 to 0.19 J when the secondary liquid is jetted, it does not depend on the type of the main liquid, does not spill, and the liquid pool of the secondary liquid Does not occur.

  In Table 1, examples where the forming and the liquid pool evaluation were performed and the kinetic energy of the secondary liquid was not obtained are indicated as “-”. This is because it is predicted that the kinetic energy exceeds the above range.
