JPH0626686B2 - Content mixing container and content mixing and discharging device using the container - Google Patents

Description

The present invention relates to a contents mixing container and a contents mixing and discharging device using the container. More specifically, in the present invention, the first content and the second content are separately stored before use, and a container that can efficiently mix and stir both at the time of use and after mixing in the container. The present invention relates to a content mixing and discharging device filled with a first content and a second content that generate internal pressure.

[Prior Art] Conventionally, products that use a reaction product formed by mixing two liquids include polyurethane foam, epoxy resin adhesives, paints, cosmetics such as hot shaving foam, hair dies, and permanent agents. Quasi drugs.

These products store two liquids separately and mix them at a predetermined ratio before use. There is no special method for mixing these two liquids. For example, the first content is placed in a container such as a beaker and the second content is added to the container and mixed with a glass rod or the like. ing.

Further, as a mixing and discharging apparatus that can easily apply the reaction product generated by mixing to the surface of another object, for example, Japanese Patent Application Laid-Open No. 60-28842
Some are described in Japanese Patent Publication.

In this product, the first content is sealed under pressure in a pressure vessel with a propellant, and an ampoule made of glass or the like filled with the second content is placed in the pressure vessel and the ampoule is crushed. A lever and a weight are attached to the container body or the inside thereof.

Further, as the same kind, there is one disclosed in JP-A-60-158073. This uses an internal container attached to the container body instead of the ampoule, and is provided with a needle or the like for punching the internal container from the outside of the container body.

[Problems to be Solved by the Invention] By the way, in the method of mixing with the beaker, it is necessary to measure each content in advance when mixing the first content and the second content, Moreover, operations such as stirring with a glass rod are required in order to make the respective contents into reaction products having a uniform composition.

Further, when the contents contain a solvent harmful to the human body, there is a possibility that the harmful solvent may be sucked when the contents are mixed. Further, for example, those having a high viscosity such as foamed polyurethane, which easily adhere to fingers, and those which must be poured into a mold are extremely difficult to handle.

Further, in the two-pack type aerosol product, the content containing the propellant is, for example, 5 to 7 kg / cm ² inside the outer container.
Since it is filled in a pressurized state, it is necessary to increase the pressure resistance and gas impermeability of the ampoule and the inner container itself. Therefore, in the conventional two-component aerosol product, an inner container or the like having a relatively high strength must be crushed or perforated from the outside of the container with difficulty.

Further, since the internal volume of the inner container is also limited, its use as a two-component aerosol product is also limited.

[Means for Solving the Problems] A contents mixing container of the present invention comprises a container body and a substantially rigid partition wall that divides the interior of the container body into two or more compartments and has an opening. An easily destructible thin film provided in the partition wall so as to close the opening and be rupturable by an external force; and an external force applied to the thin film from the outside of the container main body, which is provided in the container main body. And a means for applying the external force. The means for applying the external force is composed of a pressing operation section located outside the container body and a thin film pressing section located inside the container body.

Furthermore, the contents mixing and discharging apparatus of the present invention using the contents mixing container is a pressure resistant device in which the container body is provided with a take-out means, and the first contents to be mixed with each other in the compartment. And the second content are respectively filled in a non-pressurized state, and when the first content and the second content are mixed, two types of drugs that react with each other to generate pressure are added. Each of them is contained separately.

In the claims, it is stated that the means for applying an external force is provided in the container body, but in this case, the container body also includes a valve provided in the container body. That is, the means includes the means provided in the valve.

[Operation] As a content mixing container, two or more kinds of contents can be separately filled in a single container.

When the thin film is ruptured by using a means for applying an external force during use, it is opened almost entirely along the inner edge of the opening of the partition wall. That is, a large opening is formed in the partition.

Therefore, by holding the container body in your hand and shaking it,
The contents can be quickly and uniformly mixed and stirred. Such mixing and stirring can be performed very easily without using other tools such as beakers and glass rods.

The contents mixing and discharging device is filled with the contents in a non-pressurized state, that is, at atmospheric pressure. Therefore, manufacturing work such as filling work is easy. In addition, high pressure resistance and gas impermeability as a means to isolate contents from each other,
No need to give strength. Therefore, it is possible to employ a partition that is relatively thin and has a large area, for example, a partition that divides the interior of the container into upper and lower parts. Further, even if a thin film for forming a large opening is formed in the partition wall, it is not broken by the internal pressure difference between the compartments.

To use this product, the same operation as in the case of the above-mentioned mixing container is performed to mix and stir the contents to generate a reaction product, and the reaction product is discharged by the internal pressure generated thereby. . Various forms such as spray, foam, or liquid or gas can be adopted as the form for discharging.
