Description

  The present invention relates to a lid used for a specimen test (inspecting a test object obtained from a human body to perform a component analysis or a test for the presence or absence of microorganisms).

  Conventionally, various means have been used to close the entrance opening of the specimen test container, but as shown in the present invention, there is no sheet body type having continuous irregularities.

Conventionally, test tubes and blood collection tubes (hereinafter referred to as Spitz) are frequently used as specimen storage containers. In many cases, after completion of the test, specimens are dispensed into Spitz and the like, and each Spitz is covered with a cylindrical lid and stored in a refrigerator such as a test tube stand (hereinafter referred to as a rack).
Others are placed in a plastic bag to cover the whole rack, the upper part of Spitz is covered with an aluminum foil or film cover, and stored in a case that can be put together with the rack.
Of these, each means using a cylindrical lid is small and difficult to hold, and is made of a relatively hard material to improve hermeticity, making it difficult to work when wearing gloves to prevent infection. is there. Also, when storing the lid itself, it is stored as it is in a bag that has been opened once, or is taken out as needed by subdividing it into a slightly smaller box, and there are problems in grasping the remaining number and in terms of hygiene. Furthermore, this cylindrical lid tends to be dropped during use.
The latter means for covering the entire Spitz with the cover is poor in airtightness due to its shape, and when removing the specimen, the entire cover must be removed, and the cover once used is easily broken and difficult to reuse. Other means described above have problems such as the need for specific tools and airtightness.
In view of the above, the present invention is intended to provide a novel and useful lid for a specimen container that is inexpensive and easy to use, can be used for each specimen container, and has various advantages that are airtight. It was invented.

The present invention has the following configuration as means for solving the problems.
That is, an upper surface sheet body made of an arbitrary sheet-like material is provided, and a hollow recess having an inclined outer surface protruding downward from the sheet body with the upper surface opening being aligned with the sheet body. It is assumed that the diameter becomes smaller as it goes to.
The present invention is a specimen storage container lid having the above-described configuration. In addition, the further convenience improvement is acquired by adding a tear line part as shown in Claim 2.

The present invention has the following effects.
1. A concave portion formed by a lid is inserted into the container for use, and the concave portion has an inclined side surface that decreases in diameter as it goes downward, so that it can be pressed against the container and reliably prevent foreign matter from entering. .
2. Due to the method in which the concave portions are continuously provided, a plurality of specimens can be processed at a time.
3. By providing the cut line portion, it is possible to cut and use as much as necessary.
4). Since it is made of a thin sheet-like synthetic resin, it can be provided at a low cost.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes an upper surface sheet body made of a rectangular thin synthetic resin sheet, and 2 denotes a recess provided continuously with the sheet body at equal intervals. The concave portion is an inverted frustoconical hollow body projecting downward from the upper surface sheet body, and the inner diameter of the bottom portion 4 of the concave portion is smaller than the inner diameter of the opening portion 3 located on the sheet surface. Therefore, the outer surface of the recess has a predetermined inclination angle with respect to the direction orthogonal to the upper surface sheet. Each recessed part has a predetermined distance, and a cutoff line part 5 is provided in a direction perpendicular to the upper surface sheet body in a plan view at an intermediate position thereof.
As shown in FIG. 8, the cut line portion is provided with non-cut portions and cut portions alternately.
That is, the end cut portion 6 as a short cut portion is first provided symmetrically in a direction perpendicular to the long side of the top sheet body, and then the short non-cut portion 7 is located symmetrically on the same line, and has a long center. The cutting part 8 is located. Therefore, the adjacent concave portions can be easily separated with a finger.
In this example, as shown in FIG. 1, ten concave portions are provided continuously.

Next, the use of the present invention will be described.
Taking the case of blood collection as an example, blood collection tubes as shown in FIGS. 4 to 5 are used as an example of a sample storage container. This is a hollow cylindrical body with an open top, a transparent synthetic resin body in which a folded portion directed outward is formed at the upper end, and a gentle step portion is formed on the inner surface at a predetermined distance from the upper end. A blood sample collected in this tube is infused and stored.
Since the top of this tube is open, it must be capped to prevent unwanted objects from entering. Therefore, although there are the means described above, the present invention is presented as a more useful means.
Usually, a plurality of blood collection tubes are accommodated in a rack (test tube stand), and a portion of the tube that is sealed with a lid is the concave portion of the present invention. For example, as shown in FIG. When pressed against the mouth, the recess has an inclined side surface, so that the outer surface of the recess is pressed and adhered to the inner surface in the vicinity of the entrance of the blood collection tube as shown in the figure, thereby preventing unwanted materials from entering the tube. This recess is formed by processing a thin synthetic resin sheet, and the pressing force on the tube may be small. In this example, since 10 concave portions are formed continuously, it is possible to deal with 10 blood collection tubes at a time.

One of the features of the present invention is the inclination angle of the side surface of the recess. If this angle is too small, the compatible tube inner diameter range becomes smaller, and only a specific inner diameter can be accommodated, and the degree of pressing against the inside of the tube becomes high and it becomes difficult to remove. On the other hand, if the angle is too large, sufficient contact pressure with respect to the tube cannot be obtained, and it becomes easy to come off. As a result of experiments, it was recognized that the angle range θ is preferably between 10 degrees and 14 degrees, and that the thickness of the top sheet body and the recess is preferably 0.05 to 0.12 millimeters because it is easy to fit the tube. . In order to deal with individual blood collection tubes used at a time, in this example, as described above, a cut line portion is provided so that the individual blood collection tubes can be used separately.
FIGS. 6 to 10 show other examples of the present invention. In FIG. 3 of the example, the bottom of the recess is rounded, but FIG. 6 is an example in which the obtuse angle is formed. It is the same.
FIG. 9 shows a case where the bottom of the recess and its vicinity are bent in two steps, aiming at strengthening the recess. In FIG. 10, the concave portion is formed in a curved shape and is formed in a curved convex shape with the center of the bottom portion facing slightly upward, so that the concave portion is further strengthened.

As mentioned above, although this invention was described, this invention has the characteristic in the place which seals Spitz opening part using the sheet | seat body which provided the recessed part continuously, and the attachment or detachment is easy.
Conventionally, there is no such article, and there are various problems as described above, but this can be solved by the present invention. Since the present invention is in the form of a sheet and is easy to hold and airtight, it is suitable for sample storage, and the sample can be easily taken out. Moreover, even if it falls, it does not roll, and a hygienic and quick work is possible. In addition, it can be used one by one or several at the cut line portion, and the necessary number of Spitz after storage can be taken out. The sheet body can be stacked and stored in a case or the like, which is hygienic and can be easily managed.
In addition, the interval between the recesses in the invention is designed according to the rack size to be used, and the recess size is designed to match the Spitz size to be used, but the bottom of the recess is designed to keep the distance from the specimen moderate. It is important that the distance is 10 mm or less from the Spitz opening position. In the example, the cut line portion is configured by using the cut portion and the non-cut portion, but may be a so-called perforation in which cut portions and non-cut portions having the same length are alternately provided.
In addition, the above example shows the basic pattern of implementation and it is good also as another structure of approximation.
As described above, useful articles for a specimen storage container having various conveniences can be obtained in the present invention.
