Description of the Related Art Conventionally, as a method for artificially cultivating mushrooms using a culture medium containing a sawdust or rice bran as a main component and a nutrient source, a culture medium is filled in a cultivation bottle, sterilized, and the filled cultivation is performed. After inoculating seeds of mushrooms such as enoki mushrooms and maitake in the bottles, cover the mouth of the cultivation bottles with a cap, close the bottles, and cultivate the bacteria under predetermined temperature and humidity conditions for industrial cultivation. Or, the culture medium is filled in a plastic bag, the bag opening of the filled culture medium-filled packaging bag is folded back to the side of the bag, and the shape of the bag is shaped and maintained. There is a method of inoculating a treated and sterilized culture medium-filled packaging bag with a seed bacterium, culturing the bacterium under predetermined temperature and humidity conditions, and industrially cultivating the bacterium.

[0003] In the former case, cultivation of enoki mushrooms and the like is performed according to the diameter of the mouth of the cultivation bottle. Cannot be applied because it is not suitable. Therefore, in the artificial cultivation of shiitake mushroom, nameko, etc., the latter plastic packaging bag is used.

Due to such a problem, in recent years, the demand for the latter disposable but culture medium-filled packaging bag has been increasing.

By the way, when the packing of the culture medium into the packaging bag is manually performed, first, the bag mouth of the packaging bag is pushed open to fill a predetermined amount of the culture medium therein, and the upper surface thereof is held by a hand or a jig. After being compacted into a cylindrical shape using the method described above, an inoculation hole is formed at the center of the upper surface thereof through a push rod or the like, so that the culture medium is filled and pressure-molded so as to be bagged.
