[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for cultivating mushrooms such as enoki mushrooms, shimeji mushrooms, hiratake mushrooms, nameko mushrooms, etc. by cultivating containers such as bottles.

[0002]

2. Description of the Related Art Conventionally, in artificial cultivation of mushrooms, cultivation soil mixed with nutrients such as sawdust and rice bran is placed in a container such as a bottle, steam-sterilized, and seeds are planted in the cultivation. A method of cultivating mushrooms by culturing mycelia in a kept growth room has been adopted. In this case, when various bacteria such as bacteria (bacteria), Trichoderma bacteria, and radioactive bacteria enter the soil, the growth conditions of hyphae and the growth of harmful bacteria are similar, and the growth of mushrooms is hindered by the propagation of various bacteria.
Mushrooms are aerobic, and if the container is sealed with a material that does not allow air to flow, the growth of mycelia will be impaired. Between the caps, a cap is used in which a sheet formed by laminating a foamed polyurethane having a thickness of 5 to 6 mm or a sheet of tarpaulin paper perforated between two pieces of kraft paper is used as a filter.

[0003]

[Problems to be Solved by the Invention] Many filters of the cap currently used are foamed polyurethane, and this filter has a high porosity so that harmful bacteria can easily enter, and the filter can pass through the gap between the cap and the bottle mouth. Otherwise, a situation may occur in which the yield of mushrooms is reduced due to the invasion of harmful bacteria in the inflowing air, or the harvest may be completely eliminated. Also, kraft paper filters are not sufficiently breathable for mushroom growth.
Furthermore, since the cap has a two-layer structure for sandwiching the filter, and each has a vent, it must be manufactured with two complicated molds. It has become something.
An object of the present invention is to provide an inexpensive container that can sufficiently supply oxygen necessary for the growth of mushrooms in a container cultivation of mushrooms and that can sufficiently prevent invasion of various bacteria and the like.

That is, the cap of the container for cultivating mushrooms of the present invention has a vent hole on the upper surface communicating with the inside of the container,
Furthermore, it has an annular or a plurality of protrusions around the upper part.
The filter member is mounted on the upper or lower surface of the ventilation hole and protected by an annular or multiple protrusions, so that the filter member contacts the container or the bottom of the container even when the containers are stacked during seed inoculation or during transport work. Never do. Therefore, the filter becomes contaminated during operation,
No damage and no harmful bacteria enter the container.

[0006] The filter member used in the present invention is 0.1.
When the filter is attached to an air flow path containing a certain amount of 0.3 μm particles generated by a dust generator, the cutoff rate of 3 μm particles is 40% or more, that is, 40% or more of the upstream side dust concentration. Melt tub that can collect
It is a filter member made of a lawn nonwoven fabric . By using such a filter, the container can be ventilated without contaminating the inside of the container with harmful bacteria.

[0007] Mycelia of mushrooms are aerobic and require sufficient oxygen, but they need water in addition to oxygen for their growth. Has been adopted. For oxygen supplementation, it is preferable that the filter member has high air permeability, but excessive air permeability causes drying of the container. The maturation period of the mushroom mycelium is different depending on the type, for example, 20 days for enokitake and 80 days for braised mushrooms. It can be difficult. The amount of water evaporation can be adjusted by the number and size of the vent holes opened in the cap. It is economically advantageous to change the number of the same filter members to be laminated or to attach filter members having different air permeability to the cap manufactured by the mold described above. Also in this case, it is necessary to use a filter member having a blocking rate of 0.3 μm particles of 40% or more.

As the filter member used in the present invention, a non-woven fabric or paper is used, but a non-woven fabric having high air permeability is preferable. The nonwoven fabric can be produced by various methods such as a wet method, a card method, a spunbond method, a melt blown method, and a flash spinning method. Among them, the melt blown method or the flash spinning method using ultrafine fibers has many uniform fine pores and is preferable in terms of air permeability and bacteria-blocking property, and furthermore, the one subjected to electret processing is particularly preferable. The filter member is made of a water-repellent polymer such as polypropylene itself, or a water-repellent filter member does not penetrate into the interior even if water drops fall on the surface, and is preferable in terms of preventing contamination by harmful bacteria. Non-woven fabric used as a filter member, even in one layer,
It may be laminated with two or more layers with other nonwoven fabric, paper, reinforcing sheet, etc. for reinforcement or other purposes.

The filter member is mounted on the front surface or the back surface of the cap so as to cover a ventilation hole provided on the upper surface of the cap which is a concave portion surrounded by a ring or a plurality of protrusions.
The filter member can be attached using a pressure-sensitive adhesive or an adhesive. However, it is preferable that the filter member is thermally adhered by an ultrasonic fusion method or the like from the viewpoint of adhesion and workability between the filter member and the cap. In order to heat-bond the filter member, the filter member contains heat-bonding or heat-fusible fibers on at least the surface in contact with the cap,
Alternatively, a heat-fusible film or the like needs to be laminated on a portion in contact with the periphery of the opening of the container. Generally, polypropylene is often used as a material for the cultivation container, and it is preferable that the material be capable of being thermally bonded to polypropylene at a temperature equal to or lower than the softening point of polypropylene. A laminated structure of a material having a low softening point and a material having a high softening point or a material that does not soften and melt is preferable because heat sealing can be performed stably. Further, in order to increase the adhesion between the cap and the container, it is preferable to attach a packing such as a rubber ring to the back surface of the cap. In this case, the filter member can be installed on the back surface of the ventilation hole and fixed by the rubber ring. . The fitting portion of the cap with the container body may be of a type that is inserted into and fixed to the mouth of the container as shown in FIG. 1 or a type that is fitted over the mouth of the container as shown in FIGS. In order to prevent invasion of falling bacteria in the case of poor contact with the mouth, it is preferable that the insertion-fixing type also has a cover portion as shown in FIG.
