Abstract
[Problems]To provide a container not deformed nor burst even if its content and gas in the container inflate due to a temperature difference between before and after forming a frozen material packaging body and also capable of performing hygienic administration of the content. [Means for Solving Problems]A vent port covered with a filter material having microbial impermeability and air permeability is formed at least in a portion of the container.

1-6. (canceled)
A frozen material packaging body comprising:
- a container formed using a laminated body including at least a thin layer of paper and a thin layer of aluminum;
- and
- a vent port covered with an air-permeable filter material,
- made from an unwoven paper having microbial impermeability and air permeability of a range of 5 to 10000 sec/100 cc under JIS-P8117 (Gurley method), and formed at least in a portion the container;
- and
- frozen culture filled in the container.
A method of manufacturing a frozen material packaging body comprising:
- a step of forming a pellet-like frozen culture by dropping a culture that is incubated in a liquid medium through liquid nitrogen along with the liquid medium;
- a step of filling the pellet-like frozen culture in a a container formed using a laminated body including at least a thin layer of paper and a thin layer of aluminum and having, at least in a portion the container, a vent port covered with an air-permeable filter material, made from an unwoven paper having microbial impermeability and air permeability of a range of 5 to 10000 sec/100 cc under JIS-P8117 (Gurley method);
- and
- a step of hermetically sealing the container thus filled.
A method of freezing and fermenting a culture comprising:
- a step of forming a pellet-like frozen culture by dropping the culture, incubated in a liquid medium, through liquid nitrogen along with the liquid medium;
- a step of filling the pellet-like frozen culture in a a container formed using a laminated body including at least a thin layer of paper and a thin layer of aluminum and having, at least in a portion the container, a vent port covered with an air-permeable filter material, made from an unwoven paper having microbial impermeability and air permeability of a range of 5 to 10000 sec/100 cc under JIS-P8117(Gurley method);
- a step of hermetically sealing the container thus filled;
- a step of heating the frozen material packaging body thus sealed in an unopened state to melt the frozen culture;
- and
- a step of successively fermenting the frozen culture.
