Bag gripping clip, container, and stirring method

A stirring method for stirring a liquid using a container including a bag gripping clip, which is attachable to and detachable from a bag, in which, in a case where the bag that forms an accommodation space between a first film and a second film facing the first film is gripped by the clip, a pressing force for bringing the first film and the second film into partially close contact with each other is applied to the bag, and a partition that divides the accommodation space into a first space and a second space which communicate with each other via a communication part is formed;

• and a bag gripped by the bag gripping clip, the stirring method comprising:
• a first step of gripping the bag by the bag gripping clip;
• a second step of accommodating a liquid in the second space after the first step;
• and
• a third step of forming an air pressure difference between the first space and the second space to transfer the liquid accommodated in the second space to the first space via the communication part.

A bag gripping clip, which is attachable to and detachable from a bag,

• wherein, in a case where the bag that forms an accommodation space between a first film and a second film facing the first film is gripped by the clip, a pressing force for bringing the first film and the second film into partially close contact with each other is applied to the bag, and a partition that divides the accommodation space into a plurality of spaces communicating with each other via a communication part is formed, and
• the partition divides the accommodation space into a first space, and a second space disposed below the first space in a vertical direction,
• further comprising:
• a first abutting part that abuts on the first film;
• a second abutting part that abuts on a portion of the first film, which is different from a portion on which the first abutting part abuts;
• a third abutting part that abuts on the second film and sandwiches the bag between the first abutting part and the third abutting part to form one part of the partition separating the first space and the second space, and one part of the partition forming the communication part;
• a fourth abutting part that abuts on the second film and sandwiches the bag between the second abutting part and the fourth abutting part to form the other part of the partition separating the first space and the second space, and the other part of the partition forming the communication part;
• a first fixing part that fixes a relative position between the first abutting part and the second abutting part;
• a second fixing part that fixes a relative position between the third abutting part and the fourth abutting part;
• a first sliding mechanism for changing a relative position between the first abutting part and the second abutting part by sliding at least one of the first abutting part or the second abutting part;
• and
• a second sliding mechanism for changing a relative position between the third abutting part and the fourth abutting part by sliding at least one of the third abutting part or the fourth abutting part.

A container comprising:

• a bag gripping clip;
• a bag gripped by the bag gripping clip;
• and
• a ventilation port that is connected to each of the plurality of spaces;
• wherein the bag gripping clip is attachable to and detachable from the bag, and
• in a case where the bag that forms an accommodation space between a first film and a second film facing the first film is gripped by the clip, a pressing force for bringing the first film and the second film into partially close contact with each other is applied to the bag, and a partition, formed by the partially close contact, that divides the accommodation space into a plurality of spaces communicating with each other via a communication part, where the first film and second film are not fused, is formed, and
• wherein the partition forms a pair of downward slopes.
