BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a culture container for culturing plants and the like.

[0002]

2. Description of the Related Art As a container for plant cultivation, for example, JP-A-57 / 57
Some of them are composed of a base and a cap, as disclosed in Japanese Patent No. 141226.

[0003]

[Problems to be solved by this device] However,
In the above means, the length of the outer edge of the lid is longer than or the same as the length of the inner edge, so if water drops adhere to the inner surface of the outer edge of the lid, the outer edge of the upper portion of the main body when the lid is set again is set. Water collects between them and makes it easy for bacteria to enter the container, and it is difficult to cover when the lid is put on the base.

[0004]

[Means for Solving the Problems] The present invention provides a culture container for preventing the propagation of various bacteria, and has taken the following technical means. That is, the main body 4 and the lid 2 are provided so that the edge 1 of the hollow upper body of which the upper surface is opened can be fitted into the groove 3 of the lid 2 provided with the peripheral edge formed in an inverted U shape. The edge 5 is provided longer than the outer edge 10, and an upper wall 7 integrally formed with the inner surface 6 of the inner edge 5 is provided below the upper surface of the lid 2, and the upper wall 7 has an upward projection. 8 is provided, and the bottom surface of the main body 4 is formed in such a size that the bottom surface of the main body 4 can fit into the recess formed by the inner surface 6 of the edge 5 and the upper wall 7. On the inside,
A protrusion 9 is provided to prevent the edge 5 from contacting the edge 1 on the upper portion of the main body, and the edge 10 on the outer side of the lid 2 and / or the outer surface of the edge 1 contact the edge 10 and the edge 1 on the upper portion of the main body. The culture container was provided with the protrusions 11 for preventing the above-mentioned problems.

[0005]

When the lid 2 is attached to the body 4, the peripheral edge is inverted U
The groove 3 of the lid 2 formed in the shape of a letter is fitted into the edge 1 of the hollow main body upper part whose upper surface is open. At this time, the inner edge 5 enters the edge 1 of the body 4 prior to the outer edge 10. Then, in this state, autoclave is performed to sterilize the culture container. After that, when performing the culturing work, the lid 2 is removed and the culture product may be put into the main body.

[0006]

[Effect] When the lid 2 is put on the main body 4, the inner edge 5, which is longer than the outer edge 10, enters the space surrounded by the edge 1 of the main body 1 prior to the outer edge 10, so that the lid 2 is put on. Easily improve work efficiency. Then, the long inner edge 5 prevents water droplets attached to the inner surface of the lid 2 from entering the groove 3, so that invasion of various bacteria can be prevented. Further, even when the ventilation hole and the ventilation film are provided in the upper wall 7 surrounded by the inner surface 6 of the lid 5 and the protrusions 8, the ventilation film is not easily detached during cleaning. When the culture vessels are stacked, it is possible to prevent the culture vessels in the upper stage from slipping off and prevent the aeration membrane from being blocked. And the lid 2
It is possible to prevent water droplets adhering to the inner surface of the above from rising to the fitting portion between the groove 3 and the rim 1 due to the capillary phenomenon and introducing external germs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings. First, the main body 4 is formed of a heat-resistant material (for example, glass) into a rectangular tube having an open top, and the bottom is provided smaller than the top. An overhanging portion 12 having a predetermined width is provided in the lateral direction at the upper end of the edge 1 on the upper part of the main body.

The lid 2 is formed of a heat-resistant material (for example, glass) in a quadrangular shape, and is provided with an inverted U-shaped groove 3 into which the upper portion of the rim 1 of the main body 4 is fitted. The inner edge 5 of the lid 2 is provided longer than the outer edge 10 in the vertical direction. Further, an upper wall 7 is integrally formed on the inner surface of the edge 5 below the upper surface of the lid 2, and each corner of the upper wall 7 has a circular shape whose end portion is continuous with the inner surface of the edge 5. The protrusion 8 is provided upward. Then, holes 13 are respectively provided in the upper wall 7 in a place surrounded by the protrusion 8 and the edge 5. A thin air-permeable film 14 that closes the hole 13 is attached to the upper surface of the upper wall 7.

The projection 9 is provided on the outer surface of the edge 5 of the lid 2 so as to prevent the edge 5 and the edge 1 on the upper part of the main body from coming into contact with each other. The protrusion 9 may be provided on the inner surface of the edge 1 of the main body 4. The protrusion 11 is formed on the inner surface of the edge 10 of the lid 2,
It is provided so as to prevent the edge 1 of the upper part of the main body from coming into contact with each other. The protrusion 10 may be provided on the outer surface of the edge 1 of the main body 4.

Next, the operation will be described. First, the lid 2 is positioned on the upper side of the main body 4, and then the groove 3 of the lid 2 is placed.
The rim 1 of the main body 4 is fitted in and the lid 2 is set. And
Sterilize the culture vessel in an autoclave. Next, the lid 2
Then, the medium and the culture are put in the main body, and then the lid 2 is put on the main body 4 again.

When the lid 2 is put on the main body 4, the outer edge 10
The longer inner edge 5 precedes the outer edge 10 and the body 4
Since it enters the space surrounded by the edge 1, the lid 2 is easily covered and the work efficiency is improved. Since sterilization by autoclave is usually performed with steam, the lid 2 should be used when a culture or the like is put in.
It adheres to the inner surface of the upper wall 7. Therefore, the edge 5 of the lid 2 is provided longer than the edge 10 so that water droplets can be prevented from entering the groove 3 and invasion of various bacteria into the water droplets can be prevented. Also,
Even when the culture vessels are stacked, since the bottom surface of the main body 4 is received by the projections 8, the membrane 14 is not blocked. Further, even during cleaning, the projections 8 receive the water flow, so that the peeling of the film 14 can be prevented. Moreover, even if the main body 4 moves laterally when the culture vessels are stacked, the upper portion of the rim 5 receives the bottom portion of the main body 4, so that slipping can be prevented.

Since the protrusion 9 prevents the outer surface 6 of the edge 5 of the lid 2 and the inner surface of the edge 1 of the body 4 from contacting each other, the water droplets on the inner surface of the culture vessel are capillarity to cause the lid 2 and the body 4 to come into contact.
It does not come up to the superposed part and introduce foreign bacteria from the outside. Moreover, since the contact resistance between the lid 2 and the main body 4 is small, the lid 2 can be easily opened and closed. Since the protrusion 11 prevents the inner surface of the rim 10 of the lid 2 and the outer surface of the rim 1 of the main body 4 from contacting each other, water droplets are unlikely to adhere to the overlapping portion of the lid 2 and the main body 4, and Since it dries quickly, it is difficult for bacteria to enter the water droplets.
