Description

  The present invention relates to a test specimen container, and more specifically, watertight for collecting and storing specimens for cytodiagnosis such as sputum, saliva, and cell tissues, and test specimens such as lesion tissues and bacteria (for example, tuberculosis). The present invention relates to a sex test specimen container.

  In this type of conventional test specimen container, since the opening is narrow, there are disadvantages such as sputum and saliva spilling out of the container or adhering to the container wall. In addition, since the opening is narrow, there is a problem that it is difficult to work when taking a specimen such as sputum and saliva collected on two slide glasses and creating a microscope specimen (smear) by sliding them together.

  Also, since unused empty containers cannot be stacked, a large space is required for storage of the containers, which is inconvenient especially when a large number of containers are required, such as in the case of group screening. It was.

  Furthermore, since containers containing specimens cannot be stacked, workability is poor, and a large space is required for transportation, storage in a refrigerator, and the like.

  It is an object of the present invention to improve the conventional test specimen container and eliminate the above-mentioned problems.

  In order to achieve the above object, a test sample container according to the present invention is a container body having a wide-mouthed opening and an inverted frustoconical trunk, and a cap-shaped cap that is removably attached to the opening. A lid, and an inner diameter of the opening is set to 50 to 100 mm, and a depth of the container main body is set to 20 to 50 mm. A double cylindrical seal portion having a cross-sectional shape is formed, and at least one annular seal lip rich in elasticity is formed on the outer periphery of the seal portion (Claim 1). .

  As a preferred mode, the test specimen container according to claim 1, wherein the container main body is transparent (claim 2).

  As a preferred embodiment, the test specimen container according to claim 1 or 2, wherein the cap-shaped lid is transparent (claim 3).

  A preferred embodiment is a test specimen container in which an annular protrusion or recess is provided on the bottom surface of the bottom plate of the container body, and a recess or protrusion is formed on the top surface of the lid so that the annular protrusion is detachably fitted. ). Thereby, when a plurality of containers with lids are stacked up and down, the containers are prevented from shifting to the left and right, and the stacking of containers can be stabilized.

Since the opening of the container of the present invention has a wide-mouthed shape, it is easy to collect sputum and saliva, and troubles such as wrinkles and saliva spilling out of the container or adhering to the wall surface can be prevented. Moreover, when producing a smear, it is easy to put a slide glass directly in a container, and workability | operativity improves.
Further, a double cylindrical seal portion having a U-shaped cross section is formed on the inner lower surface of the top plate of the lid, and at least one annular seal lip rich in elasticity is formed on the outer periphery of the seal portion. Therefore, when the seal portion is inserted into the opening portion, the seal lip contacts the inner periphery of the opening portion and curves upward, and the tip portion is in surface contact with the inner periphery of the opening portion and is airtight between the inner periphery of the opening portion. And keep watertight.
Further, by making the container body transparent, the internal specimen can be easily seen from the outside. Further, by making the lid transparent, the internal specimen can be seen from above the lid.

  In addition, since the body of the container body has an inverted frustoconical shape, the lower half of the body of an empty container body that is not covered is inserted into the opening of another container body so that the container bodies are positioned at a low height. Can be stacked. Therefore, since the container bodies stacked in use can be taken one by one, the workability is good, and the storage space for the container body is small.

  If the inner diameter of the opening is outside the range of 50 to 100 mm, it is difficult to collect sputum, saliva, etc., and problems such as sputum, saliva etc. leaking out of the container or adhering to the wall surface are likely to occur. If the depth of the container body is outside the range of 20 to 50 mm, it becomes unnecessarily bulky, resulting in inconvenience in handling, storage and transportation, and inconvenience in collecting, storing and taking out the specimen. Furthermore, the workability of the smear is also reduced.

  Examples of the present invention will be described below with reference to the drawings. However, it is needless to say that the present invention is not necessarily limited to the following examples.

Example 1
As shown in FIG. 1, the test sample container of the present embodiment is formed by detachably attaching a cap-shaped lid 2 to an opening 3 of a container body 1.

The container body 1 is made of various plastics, paper laminated with a polyethylene film, and preferably made of polystyrene, methacrylic resin, polypropylene, polyethylene, polycarbonate, polyarylate, etc., and is opposite to the wide-mouthed opening 3. And a truncated cone-shaped body 4.
A male screw part 5 is formed on the outer periphery of the opening 3, and an annular flange part 6 is formed below the male screw part 5.
An annular projection 8 is formed on the lower surface of the bottom plate 7 of the body 4.

  The inner diameter D of the opening 3 is set in the range of 50 to 100 mm, and the depth H of the container body 1 is set in the range of 20 to 50 mm. If the inner diameter D is outside the above range, it is difficult to collect the soot, and troubles such as soot leaking out of the container or adhering to the wall surface are likely to occur, and the workability of the smear also deteriorates. If it is out of the range, it is unnecessarily bulky, which causes inconvenience in handling, storage, and transportation, inconvenience in collecting, storing, and taking out specimens, such as sputum, and unfavorable smear workability. Moreover, it is appropriate that the inner diameter d of the bottom plate 7 of the body 4 is about 30 to 50 mm.

  The lid 2 is made of a soft plastic such as soft vinyl chloride, an elastomer such as silicon rubber, natural or synthetic rubber, and the like, and a cylindrical portion 33 is formed on the periphery of the circular top plate 32, and on the inner lower surface of the top plate 32. A double-cylindrical seal portion 34 having a U-shaped cross-sectional shape is formed, and a recess 35 into which the annular protrusion 8 of the bottom plate 7 of the container body 1 is detachably fitted is formed on the top plate 32. Yes. A knurl 36 is formed on the outer periphery of the cylindrical portion 33.

  In addition, at least one annular seal lip 37 (2 in the figure) that is rich in elasticity is formed on the outer periphery of the seal portion 34. The seal lip 37 includes those having a triangular cross-sectional shape as shown in FIG. 2 and those having a rectangular cross-sectional shape as shown in FIGS. 3 and 4, and the seal portion 34 is located in the opening 3. When inserted, the seal lip 37 comes into contact with the inner circumference of the opening 3 and curves upward, and the tip part comes into surface contact with the inner circumference of the opening 3 so as to be airtight or watertight. (See the two-dot chain line in FIG. 2).

2 and FIG. 3 has a thick portion 38 formed at the base, thereby improving airtightness or watertightness and extending the life.
In this embodiment, the lid 2 can be made of hard plastic, and a sheet provided with the seal lip 37 can be adhered to the outer peripheral surface of the seal portion 34 of the lid 2 by adhesion or the like.
Furthermore, a concave portion 35 is formed on the top surface of the top plate 32 so that the annular projection 8 of the bottom plate 7 of the container body 1 is detachably fitted.

  The test specimen container having the above configuration is stored and used as follows.

  First, when storing or using a plurality of empty containers, as shown in FIG. 5, the lid 2 is removed from the container main body 1, and the lower half of the body 4 of the container main body 1 is connected to another container main body 1. The lower surface of the flange portion 6 of the upper container body 1 is brought into contact with the upper end surface of the lower opening 3 of the container body 1. Thereby, a slight gap 16 is generated between the upper and lower body parts 1 of the container body 1, and the upper and lower container bodies 1 can be easily separated. If there is no gap 16 and the upper and lower body parts 4 are in close contact with each other, when the upper and lower container bodies 1 are to be used separately, the space between the upper and lower bottom plates 7 becomes negative pressure and separates. This causes a problem that separation becomes difficult.

  Since the empty container body 1 can be stacked at a low height as described above, a space for storage and use can be reduced.

  Next, as shown in FIG. 1, in order to store the collected specimen 17 in the container body 1, the lid 2 is detachably attached to the opening 3 of the container body 1. At that time, when the seal portion 34 of the lid 2 is inserted into the opening 3, the seal lip 37 comes into contact with the inner periphery of the opening 3 and curves upward, and the tip portion is in surface contact with the inner periphery of the opening 3. In addition, since airtightness and watertightness are maintained between the inner periphery of the opening 3, it is possible to inject a chemical solution 18 such as physiological saline into the container body 1 when necessary.

In addition, if the container main body 1 is comprised with a transparent body, the accommodated specimen 17 can be observed from the outside. Therefore, for example, it is convenient to visually check whether the specimen 17 contains blood or not. Moreover, there is an advantage that the specimen 17 can be visually recognized from above the lid 2 by making the lid 2 transparent.
Further, the flange portion 6 of the opening 3 of the container body 1 prevents an external foreign object from hitting the lower end surface of the cylindrical portion 33 of the lid 2 and loosening the screwing of the lid 2.

  Further, the flange portion 6 can reinforce the body portion 4 of the container body 1 to reduce the wall thickness of the body portion 4, so that the used container body 1 can be discarded or reused. In this case, it can be easily crushed to reduce the bulk, so that the efficiency of storage and transportation can be improved and the material can be saved, so that the cost can be reduced.

  In order to store a plurality of containers containing the specimen 17 as described above, as shown by a two-dot chain line in FIG. 1, the containers are stacked up and down to save storage space. At that time, the annular projection 8 of the bottom plate 7 of the upper container body 1 is detachably fitted into a recess 35 formed on the upper surface of the lid 2 of the lower container. This prevents the stacked containers from shifting to the left and right, and stabilizes the stacking of the containers. Of course, a recess may be provided in the bottom plate 7 of the container body 1, and a protrusion that fits into the recess may be provided on the upper surface of the lid 2.

  In the present invention, as described above, since the opening of the container body has a wide mouth shape, it is easy to collect and store the specimen. In addition, the workability of the smear is also good.

  Further, a double cylindrical seal portion having a U-shaped cross section is formed on the inner lower surface of the top plate of the lid, and at least one annular seal lip rich in elasticity is formed on the outer periphery of the seal portion. Therefore, when the seal portion is inserted into the opening portion, the seal lip contacts the inner periphery of the opening portion and curves upward, and the tip portion is in surface contact with the inner periphery of the opening portion and is airtight between the inner periphery of the opening portion. And keep watertight.

  Further, by making the container main body a transparent body, the specimen accommodated in the container main body can be observed from the outside. Furthermore, the specimen can be observed from above the lid by using a transparent lid.

  In addition, since a plurality of empty container bodies without lids can be stacked one above the other at a low height, workability is improved because it is possible to take out the container bodies one by one when using the container body. In addition, the storage space is small. Therefore, it is convenient especially when a large number of container bodies are required, such as a mass examination.

  In addition, since it is possible to stably stack a number of containers that contain specimens and cover them vertically, a large space is required to place containers after specimen collection, transport containers, and store in refrigerators. And not.

  Furthermore, since the inner diameter of the opening of the container main body is limited to 50 to 100 mm and the depth of the container main body is limited to 20 to 50 mm, operations for collecting, storing, and taking out specimens and smear operations are possible. Easy and efficient.
