[Patent Document 2] Japanese Utility Model Publication No. 46-20317

[0003]   Generally, a threaded cap is screwed onto a threaded container to seal the mouth of the container. Place packing between container and cap. How to install the packing is Place the packing on the mouth of the vessel and screw the cap onto the inside of the cap. Either one with the packing attached is screwed into the container mouth. The sealed state of the part is that the threaded container is covered with a screw cap and fitted, Tighten the screws so that the bottom surface of the packing and the top surface of the container mouth contact all around. Starting from the tightened position of the screw (this position is called "zero touch point"), By further tightening the screw, the container mouth will not be easily sealed. Is maintained.

[0004]   Therefore, to maintain a tight seal between the threaded container and the threaded cap, The screw needs to be tightened further than the zero touch point, and also to release the seal. Loosen the screw further than the zero-touch point and leave a space between the container mouth and the packing. You need to make a gap.

[0005]   Traditionally in industry, the combination of threaded containers and threaded caps The simple operation ensures that the seal is unsealed and returns to ventilation. In addition, a sealed structure that can reliably restore the sealed state by a simple operation Is requested. For example, containers for culturing microorganisms do not allow the culture substrate to dry during culturing. In addition to the function of keeping the container mouth sealed to prevent it, it is necessary for the growth of microorganisms. Needs a function to obtain appropriate ventilation to take in the required oxygen from the outside In addition, the sealed state and the aerated state can be easily and easily maintained during the culture period. It is absolutely necessary to repeat it. In this way, it has both the function of sealing and ventilation. For the “rubber cap for culturing M. tuberculosis” that is provided, see Shoji 47-2. It is disclosed in Japanese Patent No. 0317. However, this device has a rubber cap structure. This involves opening and closing the split surface formed in the cap in response to changes in the pressure inside the container. Since it is a mechanism that operates, it is completely different in configuration from the packing according to the present invention. Of.

[0006]   A packing having an air circulation portion is disclosed in Japanese Patent Laid-Open No. 11-130127. It is disclosed. That is, this "packing for lid" is a disc-shaped or annular throat. It may be different, but the disk-shaped one has one or more through holes. The annular one has one or a plurality of arc-shaped penetrating portions. But this packing Is not intended to deform the through hole or the through part depending on how the screws are tightened. The packing is completely different from the invented packing.

[0007]   About the sealing structure that seals the container and the cap through the packing, the sealing If there are many structures, with a little movement between each container mouth and packing Make sure to create the same void and release the sealed state, and make all sealed structures the same ventilation state It's not easy to put back. The state where the screw is loosened is unstable and the position of the cap Fluctuates easily, and if the screws are loosened too much, there will be a gap between the container mouth and the packing. It gets too big and has too much ventilation, and to get it back to its sealed condition, screw Need to tighten. In addition, if the screws are loosely tightened, sufficient ventilation cannot be obtained. There are things.

[0008]   This will be explained using the microorganism culture container. In a container for microbial culture in which a conventional packing is installed between the It is necessary to loosen the cap slightly to obtain ventilation, but a lot of microbial culture is required. This operation is complicated when there is a food container, and unstable operation is required. Inevitably, depending on the degree to which the cap is loosened, the culture substrate will dry due to excessive ventilation. There is a situation in which the growth of microorganisms is suppressed due to insufficient ventilation.

[0009]   Under such circumstances, including the above-mentioned microbial culture container, a threaded container and screw Zero-touch if possible in a sealed structure consisting of a combination of caps It is desirable that the ventilation state can be reliably obtained at the point. If it is a zero touch point, It is easy to tighten the screw from that position, and use the tightened screw as the zero touch point. It's easy to put it back. Also, if it is a zero touch point, the position of the cap will shift There is no fear, and you can easily obtain a certain level of ventilation. Can be maintained. The present invention has been made to meet such a demand.

[0010]

[0018]

[Embodiment of device]

  Hereinafter, the present invention will be described in more detail.   The packing according to the present invention needs to be manufactured using an elastic material. Bullet There is no particular limitation as long as it is a material having properties, but silicone rubber, butyl rubber, urea If you use a rubber material such as tongue rubber or NBR synthetic rubber, the packing thickness and Regardless of size, the V-shaped notch can be opened and closed smoothly, so the present invention It is preferable to use rubber as the packing. In addition, foamed polyethylene or foam Since foamed synthetic resin such as polystyrene does not have a wide range of expansion and contraction, Not preferable. The packing according to the present invention is made of an elastic material. Therefore, when the screw is tightened, the V-shaped notch is deformed and both side edges are in contact. Since they are close to each other and the gaps at both ends are closed, the container mouth can be sealed. Well Also, when the screws are loosened, both ends of the V-shape will expand and return to the original shape. The vent can be returned to the vented state.

[0019]   The packing body according to the present invention may have any shape as long as the flat surface is plate-like, and is disk-like. However, other shapes may be used. The point is that a V-shaped cut is made on the outer periphery. One or more notches can be provided, and the tip of the notch is the container mouth. Any shape can be used as long as it can be formed so as to communicate with the inside of the part. I do not support it. However, screw caps and threaded containers are often cylindrical. From the standpoint of ease of use and ease of use, the packing body according to the present invention also has a disc-like shape. Those are preferable.

[0020]   In the present invention, the V-shaped notch provided on the outer periphery of the packing has a sharp point. The part is formed toward the inside (center part) of the packing. The number of cuts can be one However, for example, 2 facing each other, 3 or 4 evenly spaced, and so on. There is no problem even if several are provided. However, when the cap is tightened, all V-shapes V-shaped because it is necessary to seal the container by closing the side end of the notch The number of cuts is preferably about 1 to 4.

[0021]   Also, the V-shaped notch must be formed to a size that communicates with the inside of the container mouth. There is. Specifically, for example, the outer diameter of the mouth portion is 13.7 mm and the inner diameter is 10.5 mm. When using a 14.5 mm diameter packing for Since the distance between the end and the inner end of the container mouth is (14.5-10.5) / 2 = 2 mm, The length of the notch must be short in order for the packing to reach the inside of the container mouth. However, it is necessary to make it about 3 mm, preferably about 4 mm. This So that the V-shaped notch of the packing communicates with the inside of the container mouth. Once formed, place the packing on the mouth of the container and cover it with the zero touch point. Even when tightened up, the inside and outside of the container can be connected through the packing. Thus, the container can be maintained in an aerated state at the zero touch point. Therefore, multiple containers Even if there are several, if you make the notch of packing the same V shape, It is possible to obtain the same aeration state for all containers simply by returning to the Lotch point.

[0022]   The width of the V-shaped notch of the packing is not particularly limited, but for example, Packing made of NBR synthetic rubber when the cut length is set to 4 mm as described above. Then, the width of the cut is preferably about 1.0 to 2.0 mm.   Also, the thickness of the packing is not particularly limited, and the normal packing thickness is used. However, it is preferably about 1 to 3 mm, particularly preferably 1.5 to 2 m. It is good to set it to about m.   In addition, the container for microbial culture should be properly moistened by the humidity derived from the medium inside the container. The V-shaped notch is not affected by the length and width of the V-shaped cut, The transformation of the ring is done smoothly. Also, the cap for culturing microorganisms has a diameter The thing of 10-60 mm is generally used.

[0023]   The size of the packing according to the present invention is arbitrary and is usually the same as the inner diameter of the cap. The size may be the same, but depending on the material, loosening the screws The inner diameter of the cap so that the packing does not stick to the inner surface of the cap. It is preferable to mold it to a small size.

[0024]   As described in detail above, the packing according to the present invention includes a cap and a container mouth. The packing material, size, thickness, number of cuts and length depending on the inner and outer diameters of the In addition, the width of the cut can be appropriately selected.

[0025]

[Action]

  The packing according to the present invention has the above-mentioned structure and has a V-shaped cutout provided on the outer peripheral portion. The tip of the cut-in leads to the inside of the mouth of the threaded container, so it is possible to avoid The sealed state of the container mouth and the packing has been released, and the outside air is V-shaped. It is designed to communicate with the inside of the container through the notch. On the other hand, screw the zero touch point When tightened a little, the packing according to the present invention is made of elastic material. Therefore, the V shape of the notch is deformed, and both end portions of the V shape are brought closer to each other and the container mouth portion is To be sealed. In addition, loosen the cap a little and return it to the zero touch point, The locking shape returns to the original shape, and the notch reverts to a V shape, so the container mouth Can be returned to aeration. That is, the packing according to the present invention is a zero-tack. A slight tightening of the screw from the touch point can be used to create a sealed state. The inside and outside of the container can be brought into communication by simply returning to the Lotch point.
