Problems to be solved by the invention

[0005] By the way, when actually cultivating mushrooms using the container 1 for mushroom cultivation, the sterilization treatment of the mushroom medium K performed before inoculating the inoculum is performed in the state where the container 1 is placed in the container 1 for mushroom cultivation. When the mushroom medium is sterilized, there is a problem that the lid C disposed in the upper opening 2 of the mushroom cultivation container 1 is deformed.

That is, in this sterilization treatment, as shown in FIG. 12, a plurality of mushroom cultivation containers 1 containing mushroom culture medium K are stored in a container 16, and the container 16 is placed in a heat-pressure sterilization treatment apparatus. Although they are put in a stacked state and subjected to heat and pressure sterilization treatment (total of 8 steps in FIG. 12), the lid C has the above-described ventilation structure, that is, a synthetic structure having a ventilation structure having ventilation holes and gaps S. The lid C placed in the container 1 for mushroom cultivation, which is weak in strength because it is made of resin, is heated and pressed (100 ° C to 120 ° C) under heavy load. Therefore, deformation occurs. Specifically, as shown in FIG. As shown in FIG. 9, the central portion of the upper lid 5 falls downward and deforms. The deformation of the lid body C becomes more significant as the diameter of the lid body C increases, and the present inventors have found that the upper opening 2 of the container 1 for mushroom cultivation of the type generally used in the past is used. It is confirmed that the above deformation is likely to occur when the diameter is about 60 mm or more.

[0007] When the lid C is deformed, for example, the automatic opening and closing of the lid body in various apparatuses that perform various operations (such as inoculation and inoculation of mushrooms) after heat and pressure sterilization of the mushroom medium is improved. (Does not hold the lid C well in the lid holding part provided in various devices, or prevents the lid C from being fitted into the upper opening of the container 1 for mushroom cultivation. ) In addition, when this lid C is reused, the mushroom cultivation container 1 and the lid C cannot be fitted well, and are unstable when stacked during the heat and pressure sterilization process. There is a problem that it cannot be reused after all.

[0008] As a result of repeatedly conducting various experiments and researches, the present inventors have developed a lid attached to a groundbreaking mushroom cultivation container that has not been heretofore.

[0029] Therefore, the deformation of the lid C can be prevented as much as possible, and the force is not complicated, and a high-performance lid can be easily and reliably manufactured without any trouble in the conventional production line. be able to.

Example 1

A specific example 1 of the present invention will be described with reference to FIGS.

[0031] This example is provided with an aeration structure that is provided in the upper opening 2 of the container 1 for mushroom cultivation and ventilates the inside and outside of the container 1 for mushroom cultivation.

[0032] The mushroom cultivation container 1 according to the present embodiment is formed by integrally molding an appropriate synthetic resin member (polypropylene) as shown in Fig. 1, and has a large diameter portion 1A and the large diameter portion. It is composed of a small-diameter part 1B that is connected to the upper part of 1A and forms an upper opening 2 (this is a well-known one proposed in the past.) O In addition, when actually cultivating mushrooms, Mushrooms are cultivated by inoculating the mushroom medium K stored in the container 1 for mushroom cultivation with inoculum.

The lid C is composed of a lower lid 3 and an upper lid 5 provided on the upper portion of the lower lid 3 with a gap S therebetween.

The lower lid 3 is formed by integrally molding an appropriate synthetic resin member (polypropylene) as illustrated in FIGS. 2 and 3, and is formed on the lower surface of the substrate portion 15 having a circular shape in plan view. A cylinder 7 that is smaller in diameter than 15 and is fitted into the upper opening 2 of the container 1 for mushroom cultivation 1 is suspended, and a peripheral part 8 that is the outer position of the cylinder 7 as the base plate part 15. A vent hole 8a is provided on the outer periphery of the board portion 15, and a peripheral flange 9 protruding upward is provided on the outer periphery of the substrate portion 15. Further, the substrate portion 15 is formed inwardly of the peripheral portion 9. The rib 6 described later is projected upward, and this rib An air hole 3a is provided in the inside of 6.

[0035] Note that the width, number, and shape of the air holes 3a are appropriately set in consideration of the strength of the substrate portion 15, and specifically, the air holes 3a that constitute the substrate portion 15 as in the present embodiment. The diameter of the central circular portion 15a formed between the central circular portion 15a and the width of the linear portion 15a radiating from the central circular portion 15a is appropriately set.

[0036] Further, on the inner surface of the peripheral flange 9 of the lower lid 3, an annular locked stepped portion 9a is formed which is locked by an annular locking portion 5a 'formed on the outer surface of a peripheral flange 5a of the upper lid 5 described later. ing.

[0037] In addition, one reinforcing rib 11 is provided between the air holes 8a on the upper surface of the peripheral edge 8 of the lower lid 3, and this reinforcing rib 11 exhibits a reinforcing function against a load applied to the peripheral edge 8. To do.

[0038] The shape and number of the reinforcing ribs 11 can be changed as appropriate.

[0039] Further, when the substrate portion 15 of the lower lid 3 is fitted into the mushroom cultivation container 1, the lower surface thereof is in contact with the opening edge 2 'of the upper opening 2 of the mushroom cultivation container 1. A rib 6 is provided on the upper surface of the substrate portion 15 at a position where the opening edge 2 extends vertically, and the rib 6 has an upper lid 5 attached to the lower lid 3 as shown in FIG. When disposed, the tip portion is configured to abut against the inner surface of the upper lid 5.

Further, the rib 6 of the lower lid 3 has a predetermined width as shown in FIGS. 2 and 3, and a plurality of ribs 6 in a circular shape in plan view are provided at predetermined intervals on the outer peripheral edge of the upper surface of the substrate portion 15. It is installed side by side.

[0041] A ventilation structure is formed by the vent holes 3a and 8a between the ribs 6. When the lid C is fitted into the mushroom cultivation container 1, the outside air passes between the vent holes 8a and the ribs 6. It is introduced into the mushroom cultivation container 1 through the pores 3a (the flow of air A is shown by solid arrows in FIGS. 4 and 5).

[0042] The rib 6 having the above-described structure is a deformation of the peripheral portion of the lid C that has occurred when the containers containing the mushroom cultivation containers 1 are stacked in the heat and pressure sterilization treatment of the mushroom medium K, for example. Contribute to preventing as much as possible.

[0043] Specifically, the load P from above the lid C is strongly applied to the position where the rib 6 that is installed between the lower lid 3 and the upper lid 5 is provided. In the case of the lid C in which the conventional force shown in Fig. 2 is also proposed (when the rib 6 provided on the lower lid 3 is not in the vertical extension position with the opening edge 2 'of the upper opening 2 of the container 1 for mushroom cultivation 1) When the load P applied to the peripheral edge of C cannot be satisfactorily received, and therefore the peripheral edge of the lid C is deformed downward. (Refer to Figure 7 where the transmission of the load P is illustrated with a two-dot chain line arrow).

[0044] In this respect, in this embodiment, when the cover C is attached to the mushroom cultivation container 1, the opening edge 2 'of the upper opening 2 of the mushroom cultivation container 1 and the vertical extension position are set. Since the rib 6 is provided, the load P applied to the peripheral edge of the lid C is reliably received from the rib 6 at the upper opening 2 of the container 1 for mushroom cultivation (the transmission of the load P is two points). The load P is distributed from the upper opening 2 to the whole container 1 for mushroom cultivation 1 and deformation of the peripheral edge of the lid C is prevented as much as possible. It will be.

[0045] In addition, the rib 6 is not necessarily provided in the vertically extended position of the opening edge 2 'of the upper opening 2 of the container 1 for mushroom cultivation 1 but the rib 6 is not necessarily the upper opening 2 of the container 1 for mushroom cultivation. It is not limited to being located just above the rib. At least about half (50%) of the thickness of the rib 6 matches the opening edge 2 'of the upper opening 2 of the container 1 for mushroom cultivation 1. In order to fully demonstrate the above, this case is also included.

[0046] Further, in the container 1 for mushroom cultivation, the diameter of a circle formed by connecting the ribs 6 of the lid C is the same as the outer edge diameter of the bottom portion mounting portion of the container 1 for mushroom cultivation. Something like that has been adopted. Therefore, when other mushroom cultivation containers 1 are stacked on the lid C, each rib 6 coincides with the outer edge of the bottom placement portion of the mushroom cultivation container 1. Therefore, the load from the upper mushroom cultivation container 1 is favorably applied to the lower mushroom cultivation container 1 from the rib 6 of the lid C attached to the lower mushroom cultivation container 1. Therefore, even with this configuration, the deformation of the lid C is prevented as much as possible.

[0047] Further, the rib 6 has reinforcing ribs 12 formed on both sides of the outer surface thereof, and the reinforcement of the rib 6 is achieved by the reinforcing ribs 12, thereby further preventing the peripheral portion of the lid C from being deformed. It will be possible. The reinforcing ribs 12 may be provided on the outer surface of the rib 6 or on both the inner surface and the outer surface. The shape and number of the reinforcing ribs 12 can be changed as appropriate. Further, the thickness and width of the rib 6 are appropriately set for the purpose of reinforcement.

In the present embodiment, the rib 6 is configured by a plate-like body arranged in parallel in a circular shape in a plan view at a predetermined interval on the outer peripheral edge portion of the substrate portion 15. The ribs (reinforcing ribs 12) formed as a pair of protruding protrusions at the inner left and right positions of the respective shapes may be appropriately set so that the reinforcing ribs 12 also function as the ribs 6 or the reinforcing ribs. Only 12 It may be configured to show the function of the 6!

In addition, a filter 17 is disposed in a space surrounded by each rib 6, and each rib 6 exhibits a function of holding the filter 17.

In this embodiment, the rib 6 is formed to protrude from the lower lid 3, but may be formed to protrude from the upper lid 5.

[0051] The upper lid 5 is formed by integrally molding an appropriate synthetic resin member (polypropylene) as shown in Fig. 2, and the peripheral edge 5a Is provided on the upper portion of the lower lid 3, the peripheral rib 5 a is positioned between the peripheral rib 9 of the lower lid 3 and the rib 6, and the rib 6 is the substrate portion 19 of the upper lid 5. It is comprised so that it may contact | abut.

[0052] Further, the peripheral lid 5a of the upper lid 5 is formed with a locking portion 5a 'for locking to a locked portion 9a provided on the lower lid 3 peripheral flange 9 on the outer surface thereof.

In addition, the upper lid 5 is provided with reinforcing ribs 13 in the radial direction of the central point force on the inner surface of the substrate portion 19.

[0054] The reinforcing rib 13 prevents the central portion of the upper lid 5 from falling and deforming as shown in FIG. 10 during the heat and pressure sterilization treatment.

In the present embodiment, the reinforcing rib 13 is formed in a state that does not reach the outer peripheral edge of the upper lid 5, but may be formed in a state that reaches the outer peripheral edge of the upper lid 5. In this case, a recess into which the end of the reinforcing rib 13 is fitted is provided at the center of the tip of the rib 6. Further, the shape and number of the reinforcing ribs 13 (the number in the radial direction) can be changed as appropriate.

[0056] Since the present embodiment is configured as described above, for example, in the heat and pressure sterilization treatment of the mushroom medium K, when the containers 16 containing the mushroom cultivation containers 1 are stacked, the lid C is forced. By receiving (dispersing) the load P well, the deformation of the lid C can be prevented as much as possible.

Therefore, according to the present embodiment, the deformation of the lid C can be prevented as much as possible, and the force is not a complicated structure and has a high performance lid without any hindrance to the conventional production line. Can be manufactured easily and reliably.

Example 2

A specific example 2 of the present invention will be described with reference to FIG. [0059] In the second embodiment, the substrate portion 15 of the first embodiment is made into a different type. Specifically, as shown in Fig. 6, a circular shape communicating with the mushroom cultivation container 1 in the substrate portion 15 is used. Four vent holes 3 a are provided, and reinforcing ribs 14 formed in the diameter direction of the substrate portion 15 are formed on the substrate portion 15.

[0060] The reinforcing rib 14 prevents the central portion of the substrate portion 15 from falling and deforming as shown in FIG. 11 during the heat and pressure sterilization treatment.

[0061] The shape and number of each of the air holes 3a and the reinforcing ribs 14 can be changed as appropriate.

The rest is the same as in Example 1.

It should be noted that the present invention is not limited to the first and second embodiments, and the specific configuration of each constituent element can be appropriately designed.
