BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to monitoring of adherent bacteria for prevention of nosocomial infection in the medical field and hygiene control of home medical care, hygiene control in the food field, environmental survey of restaurants and hotels, industrial waste disposal. The present invention relates to a container for storing and transporting the wiped-out member when wiping off adherent microorganisms such as bacteria and viruses for use in management, and the container.

2. Description of the Related Art Conventionally, as a method of collecting adherent bacteria when monitoring adherent bacteria, a stamp method has been widely used in which a stamp made of an agar medium is pressed against a target point and the adherent bacteria are transferred to the agar medium and collected. It has been used. However, in this method, the agar medium used as a stamp is liable to cause dew condensation on the surface of the medium, and in a wet state, the colony separation of the bacterium is deteriorated, so that there is a problem that the collection efficiency of the bacterium is likely to vary. . In addition, the agar medium adheres to the wall or floor at the time of collection, and bacteria may grow on the adhered agar medium, which may further spread contamination by the bacteria in the hospital. for that reason,
After collecting the bacteria, it is necessary to clean the sampling point.

In terms of handling, the usable agar medium has a small area, and the area of commonly used agar medium is 7 to 10 cm ² . This area is not enough as a single area to collect, and if a larger area is required to collect the bacteria, a lot of agar medium is needed, and a lot of space is required for the culture after collecting the bacteria. However, the cost will be high. If you try to collect a large area with one agar medium and repeat stamping over a large area many times, the bacteria collected once on the agar medium will be transferred to the wall or floor again with the next stamping, Accurate collection of bacteria is not possible.

Therefore, a method of collecting adherent bacteria by wiping has been proposed instead of the stamp method. This is because the member for wiping off adherent bacteria is impregnated with physiological saline or water to wipe off the bacteria, and then the member is put into the medium,
This is a method of washing out the wiped bacteria. In this method, since the medium is not used for wiping, there is no fear of secondary contamination and there is an advantage that the area for collecting bacteria can be wide.

In this method, however, rolled cotton wool or non-woven fabric has been conventionally used as a member for wiping bacteria, but after wiping bacteria with these members, it is stored in a container filled with a growth medium. Then, it is often transported to an external organization that fixes the bacteria. When putting the wiping member into the container, be careful not to touch the opening of the container, and drop the wiping member.However, for commonly used containers, make sure that the inside diameter of the opening and the inside diameter of the body are equal. If the opening is small, it is difficult to drop the wiping member into the container.If not carefully done, it may drop out of the container or contact the opening to contaminate it. The work effect is poor when trying to collect measurement points. On the other hand, when a container with a large opening, that is, a thick container is used, it is necessary to fill a large amount of medium in order to completely immerse the wiping member in the medium.

In monitoring bacteria in hospitals, food factories, etc., many measuring points are used and a large number of wiping members are used, so that the number of containers to be transported also increases. Therefore, it is possible to forget to seal the container, and during transport, the medium inside the container may leak out to cause secondary contamination.

SUMMARY OF THE INVENTION An object of the present invention is to use a wiping member for collecting adhered microorganisms by wiping, using a member for wiping the microorganisms, and transporting them at the same time. It is easy to store the members, has excellent workability, and the filling amount of the medium is small,
In addition, it is intended to provide a container and a container thereof which are excellent in safety by preventing leakage from the container due to human error in transportation.

That is, the present invention is directed to a container body having a funnel-shaped opening at the top of a cylindrical housing, and a mechanism for fitting and sealing the opening of the container body. A container for wiping off adherent microorganisms, which comprises a cap having

A second aspect of the present invention is a container for accommodating a plurality of the storage containers, the container main body including a perforated plate for determining the position of the storage container, and the entire surface of the container main body. It consists of a lid, and the depth of the container body (the distance from the bottom of the container body to the bottom surface of the lid)
It is characterized in that it is formed almost equal to the height of the storage container with the cap fitted to the container body.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a view showing the shape of a container for an adherent microorganism wiping member according to an embodiment of the present invention.

A container body (1) having a funnel-shaped opening (3) provided on an upper part of a cylindrical storage part (2) and a top part of the opening (3) are fitted to each other to fit the container. Basically, the shape is composed of a cap (5) that can be sealed, and as shown in FIGS. 1 (b) and 1 (c), the upper end of the opening (3) is formed in a cylindrical shape (4). .

The funnel shape of the opening (3) may be a conical shape, a mortar shape, a bowl shape, or the like, and is not particularly limited, but there is no step in the portion connected to the storage section (2). desirable. If there is a step, the wiping member may not fit smoothly into the container when it is dropped into the container. The length of the opening (3) is preferably about 1/3 to 1/2 of the length of the wiping member to be stored. If it is shorter than 1/3, the inclination angle of the side wall of the opening becomes small and the opening cannot be made large.
When putting the wiping member in the container, it is difficult to operate and the desired effect cannot be obtained. For the same reason, it is desirable that the maximum inner diameter of the opening (3) is about 1.2 to 2 times the inner diameter of the storage (2). If it is more than twice, the opening becomes large and the stability becomes poor, and it becomes difficult for the container to stand alone. In order to solve such a problem, as shown in FIG. 3, the bottom of the container may be enlarged or a hakama (15) may be formed for stabilization.

The storage part (2) is generally cylindrical, but it is not limited to this, and a cylindrical cross-section may be used.

The material constituting the storage container of the present invention is not particularly specified as long as it has water resistance and a certain degree of impact resistance, is easy to mold, and is not toxic to the microorganism to be handled. Examples of such materials include polypropylene, polyethylene, polystyrene, ABS resin,
Examples of the plastic include polyethylene terephthalate, polymethylpentene, and polycarbonate.

Next, a mechanism for fitting and sealing the opening (3) of the container body (1) and the cap (5) will be described. First, as shown in FIG. 1 (a), when the opening (3) has a conical shape, the inner peripheral surface of the side wall of the cap (5) is located at a position almost in contact with the peripheral edge of the upper end of the opening (3). As shown in FIG. 2 (a), a ridge (6) having a mountain-shaped cross section is provided on a part or the entire circumference of the inner peripheral surface, or on the entire circumference of FIG. 2 (b).
Such a groove (7) is provided to fit with the peripheral edge of the upper end of the opening. When the concave groove (7) is provided, it is desirable to provide a taper at the bottom of the inner surface of the side wall of the cap (5) as shown in FIG. 2 (b).

When a cylindrical portion (4) is formed at the upper end of the opening (3) as shown in FIGS. 1 (b) and (c),
As shown in FIG. 2 (c), a ridge (8) having a mountain-shaped cross section around a part or the whole circumference surrounding the outer peripheral surface of the cylindrical portion (4).
On the other hand, when the lower surface (inner flat surface) of the cap (5) and the top of the opening (3) are aligned with the inner peripheral surface of the side wall of the cap (5), the lower side of the ridge (8) is provided. The ridge (9) is provided on a part or the entire circumference of the inner peripheral surface at a position where the ridges are fitted to each other.

Further, as shown in FIGS. 2 (d) and 2 (e), a cross section is formed on part or all of the outer peripheral surface of the cylindrical portion (4) or the inner peripheral surface of the side wall of the cap (5). Is provided with a ridge (8, 9) having a mountain shape, and concave grooves (10, 11) are provided at positions corresponding to the inner peripheral surface of the side wall of the cap (5) or the outer peripheral surface of the cylindrical portion (4), respectively. You may provide and you may make a ridge and a concave groove fit.

Between the peripheral edges of the top of the opening (3) of the container body (1) and the lower surface of the cap (5), a suitable pressing force is generated so that the projections can be sealed together or the projections and the recessed grooves. The positional relationship is adjusted, but by making the width of the ridge slightly larger, it is possible to increase the difference in the total length of the container between the non-sealed state and the closed state of the container, which facilitates identification, which is preferable.
In addition, the cross-sectional shape of the ridge is preferably semicircular or semi-elliptical, and by adopting such a shape, the cap can be easily attached and detached.

Although a container is used for transporting a large number of containers, the container according to the second invention of the present application determines the position of the storage container (23) and stably holds it, as shown in FIG. It is composed of a container body (20) containing a perforated plate (21) and a lid (22) covering the entire surface of the body (20). The holes of the perforated plate (21) are made slightly larger than the lower storage section (2) of the storage container (23) so that the storage containers (23) can be inserted and stored one by one. The perforated plate (21) is the container body (20).
May be integrally molded or may be separately manufactured and installed in the body (20).

The depth of the container body (20), that is, the distance from the bottom surface of the container body (20) to the lower surface of the lid (22) is determined by attaching the cap (5) to the container body (1) according to the first aspect of the present invention. It is made almost equal to the height of the fitted storage container (23). Therefore, if even one of the storage containers (23) stored in the container is not completely fitted with the cap, the container lid (22) cannot be closed in a predetermined state. It can be seen that the storage container (23) is incompletely sealed. Further, if the lid (22) is pressed and closed in a predetermined state, the pressing force at this time can completely seal and seal the cap of the storage container in which the cap is not completely fitted. . In this way, by using the container of the present invention for transporting the container containing the wiping member, it is possible to prevent leakage of the contents during transportation due to forgetting to close the cap due to artificial carelessness or loosening of the cap. You can do it.

In the container according to the present invention, the main body (20) and the lid (22) may be integrally formed, or they may be separately formed, and it does not matter at all. The material is not particularly limited as long as it is strong enough to be transported and handled by a transportation facility, such as metal or plastic, but in consideration of cost and disposal after use, it is made of paper. Is preferred.
