[Detailed description of the device]

[0001]

[Industrial applications]

 An object of the present invention is to provide a paper stopper cap for mushroom cultivation, and particularly, a cap effective for a mushroom cultivation paper bottle cap for mushroom cultivation bottles.

[0002]

[Prior Art]

 Conventionally, as a mushroom cultivation paper stopper cap, one having a lower lid fitted to the mouth of the culture bottle and an upper lid for stopping the paper stopper has been used (for example, Japanese Utility Model Publication No. 62-35317). The structure is such that the upper lid is covered with a cap shape with respect to the lower lid, and the outer periphery of the paper is folded and bent between the peripheral edges of the cap. Therefore, such a thing is called a paper cap.

[0003]

[Problems to be solved by the device]

 With such a structure, the durability of the paper stopper is good, but when assembling, a large force is required to bend and clamp the outer periphery of the flat paper between the peripheral edges of the cap. It was extremely difficult to assemble and replace a huge number, ranging from 10,000 to several hundred thousand. Also, simply holding the paper as a flat surface between the upper and lower lid caps has the disadvantage that various bacteria can invade and good mushroom growth cannot be guaranteed. It was.

[0004]

[Means for Solving the Problems]

 Therefore, in the paper stopper cap consisting of the lower lid 1 fitted to the mouth of the culture bottle and the upper lid 2 for stopping the paper stopper 3, the lower lid 1 includes the stopper ring 4 for the bottle mouth, the upper lid stopper ring 5, the paper receiving ring 6 and A paper receiving stay 8 having an air port 7 in the center is an integrally molded product, an upper lid 2 has a structure fitting with the lower lid 1 described above, and a paper pressing ring 9 and a paper receiving stay 11 having an air port 10 in the center 11 Is a one-piece molded product, and the paper receiving ring 6 and the paper pressing ring 9 are one or a plurality of concavo-convex fitting strips.

[0005]

[Action]

 With such a structure, a large amount of force is not required for assembling, and flat paper is pinched by the uneven fitting strips of the paper receiving ring 6 and the paper pressing ring 9 at the outer peripheral portion, so that various kinds of bacteria can be prevented. Intrusion is prevented.

【Example】

 1 to 3 show the lower lid 1, FIG. 1 is a plan view, FIG. 2 is an enlarged sectional view taken along the line AA in FIG. 1, and FIG. 3 is an enlarged sectional view taken along the line BB. As is clear from these figures, the lower lid 1 has a retaining ring 4 that fits around the bottle mouth 12 shown in FIG. 7, an upper lid retaining ring 5, a paper receiving ring 6, and an air port 7 in the center. It is an integrally molded product including a paper receiving stay 8 that The stopper ring 4 is provided with stopper ribs 4a at its inner wall at four locations for the bottle mouth. In addition, there are eight contact projections 4b on the bottle mouth. In order to make it easier to release the fitting state with the upper lid 2, a detachment slope 5a which is an inclined groove is provided at the upper edge of the upper lid retaining ring 5. Further, four long communication holes 6a are provided at the boundary between the upper lid retaining ring 5 and the paper receiving ring 6 for discharging condensed water. The upper lid retaining ring 5 is also provided with ribs 5b that maintain engagement with the upper lid. The upper surface of the paper receiving ring 6 is a holding projection 6b.

4 to 6 show the upper lid 2, FIG. 4 is a plan view, FIG. 5 is an enlarged sectional view taken along line C-C in FIG. 4, and FIG. 6 is an enlarged sectional view taken along line D-D. As shown in FIG. 7, the upper lid 2 has a fitting structure with the lower lid 1, and the paper pressing ring 9 and the paper receiving stay 11 having the air port 10 at the center are integrally formed. On the outer periphery of the paper holding ring 9, there is an engaging projection 9a for engaging the lower lid 1, and there is also a holding concave portion 9b for holding the paper stopper 3 between itself and the holding convex portion 6b on the upper surface of the lower lid 1. The protrusion 2a provided on the upper surface of the upper lid 2 has a function of preventing slippage with the bottom surface of the container when the protrusion 2a is housed in the container and stacked.

FIG. 7 shows a usage state of the paper stopper cap including the lower lid 1 and the upper lid 2. A paper stopper cap consisting of a lower lid 1 and an upper lid 2 with a paper stopper 3 sandwiched between a holding convex portion 6b and a holding concave portion 9b is fitted into the bottle mouth 12. A stop rib 4a on the inner wall of the stop ring 4 is engaged with the thick edge of the bottle mouth 12. The ribs 5b and the engaging protrusions 9a engage the lower lid 1 and the upper lid 2 and do not come off.

FIG. 8 shows a second embodiment of the paper stopper cap composed of the lower lid 1 and the upper lid 2. In this example, a recess is provided near the center of the holding projection 6b on the upper surface of the lower lid 1, and a projection is provided near the center of the holding recess 9b of the upper lid 2 so that the paper stopper 3 is sandwiched between them. The complex unevenness holds the paper stopper more firmly and at the same time prevents invasion of bacteria. As shown in Fig. 9, the dent near the center of the holding convex portion 6b and the projection of the holding concave portion 9b of the upper lid 2 are small and have a sharp shape to further improve the holding function and prevent invasion of germs. Disappear.

[0010]

[Effect of the device]

 Since the mushroom cultivation paper stopper cap of the present invention has the above-mentioned structure, it does not require a great deal of force to clamp the paper stopper during assembly, so it is extremely necessary to assemble and replace multiple pieces. It's easy. In addition, there is no invasion of various bacteria and good mushroom growth can be achieved.

FIG. 8 shows a second embodiment of the paper stopper cap composed of the lower lid 1 and the upper lid 2. In this example, a recess is provided near the center of the holding projection 6b on the upper surface of the lower lid 1, and a protrusion is provided near the center of the holding recess 9b of the upper lid 2 so that the paper stopper 3 is sandwiched between them. The complex unevenness holds the paper stopper more firmly and at the same time prevents invasion of bacteria. As shown in Fig. 9, the dent near the center of the holding convex portion 6b and the projection of the holding concave portion 9b of the upper lid 2 are small and have a sharp shape to further improve the holding function and prevent invasion of germs. Disappear. The fitting structure of the upper lid 2 and the lower lid 1 may be reversed to that of FIGS. 7 to 9 so that the upper lid 2 covers the outer surface of the upper lid retaining ring 5 of the lower lid 1.
