[Action]

 According to the present invention as set forth in claim 1, the following effects are obtained. The second container is made of a stretched plastic such as polystyrene and has a reduced strength in the direction perpendicular to the stretching direction and is easily torn by the pressing force applied to the side surface of the container. Therefore, when the first and second containers are in communication with each other, the first container made of elastic plastic that is easily elastically deformed is pressed and deformed from the outside to exert a pressing force on the side surface of the second container inside the first container. Then, as a result of causing a rupture in the second container, both the first and second containers are made to communicate through this rupture (FIG. 1 (B)). That is, both the first and second containers can communicate with each other only by exerting a pressing force on the two-liquid mixing container, and it is easy to handle.

【Example】

 FIG. 1 is a schematic view showing a two-liquid mixing container according to an embodiment of the present invention, and FIG. 2 is a schematic view showing various aspects of a sheet forming method for a second container.

As shown in FIG. 1A, the two-liquid mixing container 10 connects a first container 11 containing a first liquid and a second container 12 containing a second liquid, This is to mix two liquids.

The first container 11 is formed of a blow-molded product of elastic plastic (plastic having elasticity) such as polyethylene and polypropylene. On the other hand, the second container 12 is formed of a sheet molded product of stretched plastic (stretchable plastic) such as polystyrene. The two-liquid mixing container 10 is configured by loading the second container 12 inside the first container 11.

At this time, in the two-liquid mixing container 10, the opening 14 of the second container 12 is fitted into the opening 13 of the first container 11. Then, the opening edge portion 14A of the second container 12 can be locked in the opening edge portion 13A of the first container 11, and the sealing tool 15 attached around the opening portion 13 of the first container 11 allows The opening edge portion 14A of the container 12 is sandwiched by the opening edge portion 13A of the first container 11, and the body portion 16 of the second container 12 is suspended and held in the first container 11. The sealing member 15 is composed of a cover body 17 screwed around the opening 13 of the first container 11, and a cap 18 screwed on the base portion of the discharge nozzle 17A of the cover body 17.

Further, in the two-liquid mixing container 10, a portion of the second container 12 which is continuous with the opening 14 of the body 16 is a thin portion 16A. The thin portion 16A has a wall thickness thinner than the other portions of the body portion 16 over the entire circumference of the body portion 16.

However, as described above, the second container 12 is formed of a molded product obtained by drawing a stretched plastic sheet, and the body portion is formed at a temperature equal to or lower than the melting point of the plastic material by the sheet molding method. It is stretched in 16 axial directions and the molecules are oriented parallel to the pulling direction. This reduces the strength of the second container 12 in the direction perpendicular to the stretching direction, that is, in the circumferential direction of the body portion 16, and makes it easy to tear in the longitudinal direction at each circumferential portion of the body portion 16.

As the sheet forming method for forming the second container 12 described above, for example, the following various methods are adopted (FIG. 2). (A) Straight molding (Fig. 2 (A)) A plastic sheet clamped on a mold is heated by a heater to exert a vacuum suction force applied to the inner surface of the mold on the lower surface of the sheet.

(B) Plug Assist Molding (FIG. 2 (B)) A plastic sheet clamped on a mold is heated by a heater, and a vacuum suction applied to the inner surface of the mold while exerting a pressing force of the plug on the upper surface of the sheet. A force exerted on the lower surface of the seat.

(C) Pneumatic molding (FIG. 2 (C)) The plastic clamped on the mold is heated by the heater, and the vacuum applied to the inner surface of the mold is applied while the compressed air applied to the heater is applied to the upper surface of the sheet. A device that exerts suction force on the bottom surface of the sheet.

(D) Combined use of vacuum and compressed air (FIG. 2 (D)) The plastic clamped on the mold is heated by a heater to exert the pressing force of the plug on the upper surface of the sheet, and to compress the compressed air applied to the plug. While exerting on the upper surface of the sheet, exerts a vacuum suction force applied to the inner surface of the mold on the lower surface of the sheet.

In addition to the sheet molding described above, stretch blow molding may be used as a method for forming a molded product by stretching a stretched plastic.

The operation of this embodiment will be described below. The second container 12 is made of a stretched plastic such as polystyrene and has a reduced strength in the direction perpendicular to the extending direction and is easily torn by the pressing force applied to the side surface of the container. Therefore, when the first and second containers 11 and 12 are in communication with each other, the first container 11 formed of elastic plastic that is easily elastically deformed is deformed by pressing from the outside, and the second container in the first container 11 is deformed. When a pressing force is applied to the side surface of the container 12, a rupture 20 is generated in the second container 12, and as a result, the first and second containers 11 and 12 are communicated with each other through this crevice 20 (FIG. 1 (B)). ). That is, the first and second containers 11 and 12 can be communicated with each other only by exerting a pressing force on the two-liquid mixing container 10, and it is easy to handle.

The first container 11 is made of elastic plastic and is elastically deformable, but is tough. The second container 12, which is easily broken by the pressing force, is loaded in the tough first container 11 at the manufacturing stage and the distribution stage, does not easily cause the tear 20, and can maintain the integrity of the seal. .

The sealing tool 15 attached around the opening 13 of the first container 11 holds the opening edge 14 A of the second container 12 between the opening edge 13 A of the first container 11 and the second container 12. Is suspended and held in the first container 11. Therefore, not only the opening 13 of the first container 11 but also the opening 14 of the second container 12 is sealed by the single sealing tool 15, and the overall configuration of the two-liquid mixing container 10 is simplified. You can

The wall thickness of the container body near the opening 14 of the second container 12 is made thinner than the other portions, and the thin portion 16A is weakened. Therefore, when the first and second containers 11 and 12 are communicated with each other, a force applied from the outside of the first container 11 causes the aforementioned split 20 to occur in the body portion 16 of the second container 12, and the second container The fragile thin portion 16A provided in the body portion near the opening portion of 12 is broken, and the crevice 20 of the second container 12 is generated. The body portion 16 is separated from the opening portion 14 side so that the first container 11 By dropping the mixed liquid inside, it is possible to improve the dischargeability of the second mixed liquid from the discharge nozzle 17A of the cover body 17 screwed around the opening 13 of the first container 1.
