Description

[Detailed Description of the Invention] ■ Background Technical Field of the Invention The present invention relates to improvements in test containers used for culturing bacteria, such as Petri dishes and Petri dishes.

PRIOR ART Most of the conventional test containers have a cylindrical container body fitted with a cylindrical lid having a diameter larger than the container body.

In addition, as shown in FIG. 1, a peripheral wall is provided inside the side wall of the container body at equal intervals to the side wall.

Problems with the Prior Art In the combination of a cylindrical container body and a cylindrical lid having a larger diameter than the container body, the part where the side wall of the container body and the side wall of the lid come into contact is separated by some distance to facilitate opening and closing. Because
When carrying the entire container, it was sometimes the case that only the lid was lifted by mistake.

Also, even when you lift both the container body and the lid, the part that can hold the container body is slightly loose, so it is difficult to put your fingers on the container body, and you often drop the container body, causing damage to the container body. Sometimes the contents of the container were spilled.

Therefore, the user had to hold it with both hands, making operation cumbersome.

In particular, when the fingers are wet, they tend to become slippery, which is an inconvenience even though sufficient care and speed are required.

Also, although containers like the one shown in Figure 1 have become easier to carry, they have also become larger and larger.
It became necessary to increase the storage space for containers.

In addition, double walls are formed on the sides of the container, making it difficult to observe the bottom and inner peripheral surface of the container from the outside.

■ Purpose of the invention The present invention was made by paying attention to the above-mentioned circumstances. In an inspection container comprising a cylindrical lid that is closed at one end and opened at the other end and is fitted onto the container body, a holding protrusion is provided on the outer peripheral surface of the side wall of the container body, and the side wall of the lid is The present invention provides a test container characterized in that a cutout portion larger than the holding protrusion is provided on the outer peripheral surface of the lid from the lower edge of the side wall of the lid.

The present invention also provides a test container in which the holding protrusion is provided with projections and depressions.

Furthermore, there is provided a test container in which the holding protrusions are provided at two opposing locations on the outer circumferential surface of the side wall of the container body, and the cutting sections are provided at two opposing locations on the outer circumferential surface of the side wall of the lid. It is something to do.

(2) Detailed Description of the Invention FIG. 2 shows an embodiment of the test container of the present invention, in which reference numeral 1 indicates a test container made of synthetic resin such as polyethylene or polypropylene.

This material may be glass or other material.

This test container 1 consists of a container body 2 and a lid 3.

The container body 2 preferably has a tapered shape with a depth of 1077E111, an inner diameter of 35 mm on the open end side, and an inner diameter of 33.4 mm on the closed end side.

The thickness of the side wall portion 4 and the flat portion 5 of this container body 2 is preferably 0.6 mm.

The holding protrusion 8 provided on the outer circumferential surface of the side wall 4 preferably has a length of about 41rgR1 and a width of about 175 of the outer circumference of the main body.
The thickness is 3rra.

The lid 3 preferably has a depth of 8TfgIL1 and an inner diameter of 3 on the closed end side.
6.877111. Inner diameter of open end side 37.8rIrln
It has a tapered shape.

The thickness of the side wall portion 7 and the flat portion 6 of this lid 3 is preferably 0.
．． There are 6 temples.

The cutout 9 provided in the side wall 7 preferably has a length of 5 rr.
rrn, the width is about 174 lengths of the outer circumference of the lid.

2 so that the holding protrusion 8 and the cutout part 9 correspond to each other.
More than one location may be provided.

Further, the shape is not limited to the above embodiments, and may be circular, triangular, etc.

Furthermore, it is preferable to provide anti-slip properties by attaching letters to the holding protrusion so as to create unevenness or by performing surface treatment such as embossing.

■ Specific effects of the invention Test containers are used for various purposes such as culturing bacteria, but they are very often carried in the hand.

The lid 3 is placed over the container body 2 so that the holding protrusion 8 of the container body 2 and the cutout portion 9 of the lid 3 are aligned.

Since the cutout part 9 is larger than the holding protrusion 8, the holding protrusion enters the cutout part without difficulty.

After this, the operator carries the container body 2 with the lid 3 fitted.The operator presses the holding protrusion 8 of the container body with his thumb and holds the side wall of the lid 3 opposite to this part. It is carried by holding it in place with your middle or index finger and holding it in place from both sides.

When removing the lid 3 from the container body 2, hold the outer peripheral surface of the side wall portion 7 of the lid other than the cut portion between two fingers.

Furthermore, even if the holding protrusion is provided at two locations on the container body and the cutout is provided at two locations facing the lid, if the lid is placed over the container body so that the holding protrusion and the cutout are aligned. Since the cutout is larger than the retaining protrusion, the retaining protrusion can enter the cutout without any problem.

Thereafter, the operator holds the holding protrusion of the container body directly with two fingers and carries the container by holding the container between the two fingers.

When removing the lid from the container body, hold the outer peripheral surface of the side wall portion other than the cut portion between two fingers.

Furthermore, if the holding protrusion is given surface treatment such as text or embossing so as to have unevenness, fingers will fit into the grooves formed in the holding protrusion, and the holding protrusion will be held securely.

■ Specific effects of the invention According to the testing container of the invention, it is possible to
The device can be easily carried with only two fingers on one hand and can be easily operated without accidentally dropping the container and damaging the container or spilling the contents of the container.

Moreover, the size of the container can be maintained the same as the conventional one, and it is not difficult to observe the bottom surface, inner periphery, etc. of the container.

Furthermore, a plurality of holding protrusions 8 of the container body 2 and a plurality of cutouts 9 of the lid 3 may be provided so that they correspond to each other, or a plurality of holding protrusions 8 may be provided.
It can be carried even more easily by adding letters to create unevenness or by applying surface treatments such as embossing.

Therefore, in this field where speed is required, the present invention allows speedy operation and greatly contributes to shortening inspection time.
