Description

This disclosure relates to a mixing container capable of mixing two or more liquids without incorporating air bubbles, and to a mixing method using said mixing container. In fields such as semiconductors and precision equipment, liquid materials are widely used as coatings, sealants, and adhesives. These liquid materials are mixed immediately before use, with two or more components being combined. To achieve their desired performance, the liquid must harden; therefore, the main component and hardener are mixed immediately before use. Since hardening occurs over time after mixing, applying a hardened liquid to the intended application site results in changes to its properties, such as viscosity, preventing it from performing optimally. A mixing container is needed that allows for the rapid mixing of two or more liquid materials immediately before use, enabling quick and efficient use of the mixture. A packaging bag has been proposed that has two separate compartments for different liquids, and that allows the seal between adjacent compartments to be opened by external pressure, enabling the mixing of the two liquids (see Patent Document 1). A container has been proposed for mixing two liquids by fitting the openings of two containers, each containing a liquid with a flexible resin wall, together using a connecting material (see Patent Document 2). A container has been proposed that allows for the mixing of two or more liquids by stacking containers for liquids and piercing the film between them (see Patent Document 3). Japanese Utility Model Publication No. 57-105272Japanese Unexamined Patent Publication No. 10-194353Japanese Patent Publication No. 2015-67317 A mixing container according to an embodiment of this disclosure is shown.A cross-section of a mixing vessel according to an embodiment of this disclosure is shown.The present disclosure shows a method for manufacturing a mixing container according to an embodiment of this disclosure.This invention provides a method for manufacturing a flexible film for a mixing container according to an embodiment of this disclosure.This shows a mixing-promoting structure for the mixing section of a mixing container according to an embodiment of the present disclosure.This shows a mixing-promoting structure for the mixing section of a mixing container according to an embodiment of the present disclosure.Other mixing vessels relating to embodiments of this disclosure are shown.Other mixing vessels relating to embodiments of this disclosure are shown.The mixing method according to the embodiments of this disclosure is shown.The mixing method according to the embodiments of this disclosure is shown. A mixing container according to an embodiment of this disclosure is shown in Figure 1. The mixing container is made of a material including a flexible film. It may be made of two flexible films. It may be made of one flexible film and one rigid sheet. It may also be made of one flexible film. Figure 1 shows a plan view of a mixing container composed of two flexible films or one flexible film and one rigid sheet. Figure 1(A) shows the container equipped with filling sections 1A and 1B for filling liquids. The mixing container according to this application is for mixing liquids, and the liquids to be mixed are two or more types. Different liquids are filled into filling sections 1A and 1B. In Figure 1, two filling sections 1 are shown, but three or more may be provided. When the mixing container is composed of two flexible films or one flexible film and one rigid sheet, the two flexible films or one flexible film and one rigid sheet are partially bonded together to form the filling section 1. Bonding is preferably done by heat sealing. Partial bonding using an adhesive is also acceptable. In Figure 1(A), filling sections 1A and 1B are provided adjacent to each other via an adhesive section 6. Adjacent to filling sections 1A and 1B, a first fluid section 3, a mixing section 2, and another second fluid section 3 are provided sequentially. Filling sections 1A and 1B are individually filled with liquid and then sealed. When filling the filling section 1 with liquid, it may be done through the filling port 4. In Figure 1, the filling port 4 is not adhesive and therefore not sealed. However, after filling the required amount of liquid into filling sections 1A and 1B through the filling port 4, the inner surfaces of the filling port 4 are adhesively sealed. The adhesive section 6 provides the sealing. After filling the filling sections 1A and 1B with the liquid, the mixing container is exposed to reduced pressure with the filling port 4 open to remove gases contained in the liquid and any remaining gases in the filling sections 1A and 1B. After removing the gases, the inner surfaces of the filling port 4 are sealed together under reduced pressure. This is to prevent gases from entering the mixture when the liquids are mixed. Alternatively, the entire mixing container may be exposed to
