Description

[Detailed Description of the Invention] The present invention relates to a shiitake mushroom seed bag, and more particularly to a packaging bag that functions as an incubator and packaging container for shiitake mushroom seeds.

Conventionally, artificial cultivation of shiitake mushrooms has been carried out by driving a piece of wood with a shiitake seed fungus called seed sesame into the withered trunk of a shiitake, chestnut, nara, etc., and then planting the shiitake mushroom inoculum into the shiitake, chestnut, nara, etc. In this Shiitake cultivation, as seed sesame seeds with Shiitake starter bacteria, sesame wood chips are placed in a polyethylene narrow-mouth bottle container, culture solution is added, and ventilation holes are made in the top of the cap.
Then, cover the mouth of the bottle with a breathable cap with a sponge attached to the back of the top plate, steam sterilize it, open the lid, put the Shiitake mushroom starter into the container, and close the mouth of the bottle again with the breathable cap. The lid is then left in an atmosphere of temperature and humidity suitable for culturing bacteria for the required period of time. In the process of cultivating this shiitake starter, the polyethylene narrow-mouth bottle container used as the incubator does not have a wide mouth, so it is not only difficult to put in and take out the seeds and fill the culture solution, but also when not in use. The disadvantage is that it takes up a lot of space to store.

The inventor of the present invention, as a result of research to eliminate the drawbacks of the polyethylene narrow-mouth bottle containers conventionally used as culture vessels for shiitake starter, developed a self-standing bag with a foldable bottom plate that can be opened and closed at the bottom of the bag. By opening one or more ventilation holes in the upper part of the side plate, blocking the ventilation holes, and gluing a breathable sheet to the inner surface of the side plate of the self-supporting bag, the wide opening makes it easy to fill with sesame seeds and culture solution. In addition, the inventors discovered that the incubator can be folded when not in use, which not only saves storage space, but also costs less than conventional products. Based on this knowledge, the present invention was completed.

That is, the gist of the present invention is to stack two relatively flexible plastic films that will serve as the side plates, and then sandwich the same film folded in half to serve as the bottom plate between the two films and heat seal them. The bag has a folded bottom plate that can be opened and closed at the lower part of the bag, one or more ventilation holes are opened in the upper part of the side plate, and a breathable sheet is provided on the inner surface of the side plate to cover the ventilation holes. This is a shiitake mushroom seed bag characterized by the fact that it is glued with.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

1 to 4 show the shiitake mushroom bag 13 of the present invention, FIG. 1 is a front view, FIG. 2 is a sectional view taken along line A-A shown in FIG. 1, and FIG. B-
It is a sectional view taken along the line B.

For example, a bifold bottom plate is sandwiched between a pair of side plates at a position corresponding to the lower part of the side plates, the open ends between the side plates are heat-sealed, and the open ends between the side plates and the bottom plate are heat-sealed. Furthermore, at least one of the side plates 1 and 2 of the self-supporting bag has a foldable bottom plate that can be opened and closed at the lower part of the bag, which is formed by heat-sealing the lower ends of both sides of the side plates to each other through the notch of the bottom plate. One or more ventilation holes 4 are opened in the upper part, and a breathable sheet 5 is bonded to the inner surface of the side plate 1 to close the ventilation holes 4. This breathable sheet 5 is a band-shaped body with a length extending to both side edges of the side plate, and both ends in the longitudinal direction of the breathable sheet 4 are clamped and fixed to both side heat-sealed parts 6 of the bag, and both ends in the width direction of the breathable sheet 4 are fixed. Areas 7, 8 along the edges are locally thermally bonded to the inner surface of the side plate 1. In the figure, 9 is the heat-sealed portion between the side plate 1 and the paper 5 in the areas 7 and 8, 10 is the heat-sealed portion between the bottom plate 3 and the side plates 1 and 2, 11 is the notch in the bottom plate 3, and 12 is the notch. This is a heat-sealed portion between the side plates 1 and 2 through the portion 11.

In the present invention, materials for the side plates 1 and 2 include, for example, biaxially oriented polyester, unoriented nylon, biaxially oriented nylon, unoriented polypropylene, unoriented polyethylene, polyvinylidene chloride,
Alternatively, a laminated film thereof can be used.

Next, in the present invention, as the material for the bottom plate 3, biaxially stretched polyester, unstretched nylon, biaxially stretched nylon, unstretched polypropylene, unstretched polyethylene, polyvinylidene chloride, or a laminated film thereof can be used. .

Next, in the present invention, as the breathable sheet 5, paper, Japanese paper, nonwoven fabric, polyethylene mixed paper, polypropylene mixed paper, paper impregnated or coated with thermoplastic resin, etc. can be used.

Instead of adhering a part of the air permeable sheet surface to the inner surface of the side plate as shown in the first figure, the air permeable sheet 5 may be attached to the inner surface of the side plate by adhering the entire opposite air permeable sheet surface to the inner surface of the side plate. good.

Using the above-mentioned shiitake seed bag of the present invention, put the seed sesame wood chips into the bag from the wide bag opening, then fill with culture solution, easily seal the bag opening with a clip, etc., and then steam sterilize. , then open the bag opening and
After putting the Shiitake mushroom starter into the bag, the bag opening is heat-sealed and placed in an atmosphere of temperature and humidity suitable for culturing the bacteria for a required period of time to produce seed sesame seeds with the Shiitake starter and sell them on the market. can be provided to Figure 4 shows the shiitake seed bag 1 shown in Figures 1 to 3.
Sesame seeds 14 with Shiitake mushroom inoculum are housed in the container 3, and the bag opening is sealed.

As described above, the shiitake seed bag of the present invention can be effectively used for producing sesame seeds with shiitake mushroom seeds, and since it can be folded when not in use, it does not take up much storage space. In addition, the shiitake seed bag of the present invention can be manufactured at a significantly lower cost than conventional narrow-mouth polyethylene bottle containers.

5 and 6 show another embodiment 16 of the shiitake mushroom bag according to the present invention, FIG. 5 is a plan view, and FIG. 6 is a sectional view taken along the line C--C in FIG. 5.

This embodiment differs from the embodiments shown in the first to fourth figures in that a concavo-convex fitting type fastener 15 for opening and closing the bag is provided near the bag opening.

If the bag of this embodiment is used, the bag opening can be easily opened and closed, making handling easier.

As detailed above, according to the Shiitake seed bag of the present invention, it is easy to fill with sesame seed pieces and culture solution, and since it can be folded when not in use, it not only takes up less storage space, but is also cost-effective. It has the advantage of being cheaper than other products.
