Description

Specimen container {SPECIMEN CONTAINER}

The present invention relates to a specimen container. In detail, it relates to a sealed sample container for preservative solution that accommodates and seals the preservative solution, thereby improving worker safety.

Liquid-based cytology is a technique that replaces the conventional cytology test (Papanicolaou) by storing collected cell samples in a preservation solution and then placing the cell sample with a monolayer of preserved cells evenly dispersed on a slide and examining it. It was also developed. Compared to conventional cytology tests, liquid cytology improves cell fixation and minimizes unclear factors, resulting in excellent specificity and sensitivity.

Meanwhile, cell tissue collected from the patient's lesion is transported to a location with testing equipment for accurate diagnosis of the disease. In this case, the movement of the collected cell tissue needs to be preserved for a fairly long time, so it is stored in a preservation solution (or fixative solution). The preservative solution maintains and preserves the state at the time of collection so that the cell tissue shed from the human body does not die, decompose, degenerate, or change shape, maintaining a state suitable for observing or analyzing the structure of the cell tissue, or making specimens, etc. It performs the function it commands. A mixed solution containing formaldehyde is usually used as a preservative solution.

Formaldehyde has a coagulating and polymerizing effect on proteins and is most commonly used as a main ingredient in preservation solutions. However, formalin (formaldehyde solution) is not only highly toxic to the human body but is also volatile, so caution is required when handling it. Additionally, if volatilized formalin is left in the air for a long time, grade 1 carcinogens may be generated. If a person is exposed to gaseous formalin, formaldehyde can penetrate through the skin or mucous membranes. In particular, a high degree of caution is required when handling formalin because continuous inhalation of formaldehyde can cause central nervous system disorders or heart failure.

However, workers performing cell preservation processes are always exposed to formalin. Therefore, when handling formalin, workers wear gas masks to minimize the harm caused by formalin, but despite this, workers' health is exposed to harmful elements. For this reason, various attempts are being made to seal the preservation solution.

The prior art documents described disclose a structure in which a preservative solution is sealed using a thin film sheet, the cap is rotated, the thin film sheet is cut using the structure, the preservative solution is poured out, and the specimen is immersed in the preservative solution.

However, this structure of sealing the preservation solution using a thin film sheet has several problems. Medical devices such as specimen containers are collectively disposed of as medical waste after use. The thin film sheet of the prior art is composed of aluminum foil, etc., but there is a problem of causing environmental pollution by mixing and disposing of the hard plastic material and aluminum material that constitutes the container.

A more important point is the issue of the adhesive method between the container cap and the aluminum foil. The prior art often uses adhesive to attach aluminum foil to the bottom of the cap. As time passes after the specimen container is produced, the adhesive or aluminum components may leach out into the preservative solution due to the preservative solution such as formaldehyde that comes in contact with the adhesive, or the preservative solution may penetrate into the adhesive, and in severe cases, the preservative solution may leak out through the infiltration. I also do it.

In addition, as described above, a specimen container with a sealed preservative solution is being developed to prevent workers operating the specimen container to immerse the specimen in the preservative solution from being exposed to formalin. However, a thin film sheet is used to seal the formalin. When using it, the manufacturing process of the sample container is not simple, and the time that formalin is exposed to the air during the manufacturing process of the sample container is inevitably long. In short, according to the prior art, formalin must be injected into the cap, adhesive applied to the end, and a thin film sheet placed on it to cure it. However, in the process of manufacturing such a container, the time the formalin is exposed to the air is very long, and therefore, it may cause damage to specimen workers. It is merely a solution that transfers possible safety problems to the operators manufacturing the sample containers.

Accordingly, the problem to be solved by the present invention is to provide a sample container with a structure in which the preservative solution is sealed in a different way from the conventional method.

Another problem to be solved by the present invention is to provide an accessory member used in the above sample container, for example, a flow path providing member.

It is configured to interfere.

The lower outer peripheral surface of the member may have a locking groove, and when the bottom portion is arranged to face downward, the locking groove may have a shape whose depth increases as it goes counterclockwise in plan.

When the cap is coupled to the upper part of the container body and the member is coupled to the lower part of the cap, when the cap is rotated relative to the container body, the cap and the member may rotate together and move downward.

In addition, when the cap is further rotated, further rotation and downward movement of the member is prevented due to interference between the side surface of the post and the side step of the groove, while the cap is configured to rotate further and move downward. You can.

When the cap and the member rotate together, the relative position between the cap and the member in the vertical direction can be maintained.

Additionally, when the cap and the member rotate together, the separation distance between the bottom of the main body and the member may decrease.

In addition, when the cap and the member rotate together, the post may be at least partially inserted into the locking groove, so that the post and the member overlap in the horizontal direction.

And when the cap and the member rotate together, with respect to the member, the post moves counterclockwise on a plane within the locking groove, and the insertion depth into the locking groove can increase.

In a state where the side of the post and the side step of the groove are in contact with each other, the upper surface of the post may be in contact with the upper step inclined surface of the locking groove.

A sample container according to another embodiment of the present invention for solving any of the above problems includes a container body; a container cap configured to be coupled to the container body; and a sealing stopper configured to engage with the cap, wherein the cap includes a cap ceiling portion, a cap wall portion protruding downward from the cap ceiling portion, and one or more blocking protrusions further protruding downward from a bottom of the cap wall portion.

The blocking protrusion may be inserted between the stopper partition and the stopper wall part so that its inner surface is adhered to the outer surface of the stopper partition, and can be configured to seal the passage opening.

In addition, when the cap is coupled to the upper part of the container body and the stopper is coupled to the lower part of the cap, when the cap is rotated relative to the container body, the cap and the stopper may rotate together and move downward. .

In addition, when the cap is further rotated relative to the container body, the cap is prevented from rotating and moving downward due to interference with the container body, while the cap rotates and moves downward, and the blocking protrusion of the cap The alignment of the passage opening may be misaligned.

The hole in the bottom of the stopper may be located only between the stopper partition and the stopper wall, and may not be located in an area surrounded by the stopper partition.

The stopper diaphragm portion has a ring shape in plan, and the stopper diaphragm portion includes a first diaphragm portion having a first height and a second diaphragm portion having a second height smaller than the first height. The side surface of the first partition wall and the upper surface of the second partition wall form the passage opening, and the hole and the second partition wall part may be aligned in a radial direction.

Referring to FIGS. 1 to 8 , the sample container 10 according to this embodiment may include a container body 100, a container cap 200, and a sealing stopper 300. Here, the stopper 300 functions as a stopper of the container cap 200, and the container cap 200 and the stopper 300 can form a sealed internal space together depending on the degree of rotation between them. In addition, as will be described later, the sealing stopper 300 is located in a path through which a liquid substance, that is, a preservative solution, flows from the container cap 200 to the container body 100, and the poured liquid substance flows through the hole 310H of the sealing stopper 300. ) can flow through. Although not shown in the drawings, the sealed internal space may contain a preservation solution (or fixative solution) for preserving or fixing cell tissue, with or without formaldehyde.

The container body 100 (or sample container) may be a substantially cylindrical container with an open top. The container body 100 includes a main body bottom 110 and a main body wall 130 protruding upward from an edge of the main body bottom 110, and the main body wall 130 is located at the main body bottom 110. A first stopper 170 (or stopper bar, or stopper protrusion, or support bar, or post, or protrusion) disposed in the surrounding space and a first coupling portion disposed on the upper outer peripheral surface of the main body wall portion 130 ( 190) (or a first screw thread, or a body screw thread, or a body coupling member, or a first coupling means, or a first coupling structure, or a first coupling element) may be further included.

Here, the first stopper 170, together with the second stopper 370, which will be described later, may refer to a configuration that limits the relative degree of rotation between the container body 100 and the stopper 300. The first stopper 170 may be fixed in position inside the container body 100, specifically on the body bottom 110. In addition, the first coupling portion 190 may refer to a configuration that forms a reversible coupling between the container body 100 and the container cap 200 together with the second coupling portion 290, which will be described later.

The body bottom 110 may have a substantially circular shape. The main body bottom 110 may provide a floor space in which objects accommodated within the container main body 100, such as a tissue (specimen) to be tested or a preservative solution, are accommodated. The body bottom 110 may provide a planar space to which the first direction (X) and the second direction (Y) approximately belong, but the present invention is not limited thereto. In another embodiment, the planar center of the body bottom 110 may be relatively high and may become lower toward the edge.

The first coupling portion 190 includes a screw thread, and the container body 100 and the container cap 200 may be thermally coupled and released using the first coupling portion 190. The coupling and disengagement may be performed by screw tightening. A screw tightening coupling may be a coupling in which the vertical distance between a plurality of components changes according to or in proportion to the relative rotation between the plurality of components. In other words, it is different from a fit coupling or an interference fit coupling in that rotation and linear movement are dependent on the inclination of the pre-designed screw thread.

A first stopper 170 may be disposed on the body bottom 110. Specifically, the first stopper 170 may be disposed in a space surrounded by the main body wall part 130 on the main body bottom part 110. The first stopper 170 may come into contact with the main body wall portion 130. In an exemplary embodiment, the first stopper 170 extends in the third direction (Z) and may have a bar shape protruding inward from the main body wall portion 130. As a non-limiting example, four first stoppers 170 may be provided in a rotational or circular arrangement at an angle of about 90° based on the planar center of the main body bottom 110. The first stopper 170 may function as a stopper using a predetermined height in the third direction (Z), for example, near the top. The first stopper 170 may provide a lowering limit and/or a rotation limit in the third direction (Z) of the stopper 300 with respect to the container body 100. The operation of the first stopper 170 will be described later.

The above-described main body bottom 110, main body wall 130, first coupling part 190, and first stopper 170 may be formed integrally with each other without physical boundaries, but the present invention is not limited thereto. .

The container cap 200 (or a preservative solution receiving portion, a container stopper, or a container lid) may have a shape with an open bottom. The container cap 200 may be configured to seal the internal space of the sample container 10 by covering the upper opening formed by the main body wall portion 130 of the container body 100. That is, the container cap 200 functions as a container with a sealed interior along with the container body 100, and can selectively seal the interior together with a stopper 300 to be described later and accommodate a preservative solution.

The container cap 200 includes a cap ceiling 210, a cap wall 230 protruding downward from the cap ceiling 210, and a blocking protrusion 250 further protruding downward from the cap wall 230, A fastening body 280 protruding downward from the edge of the cap ceiling 210 and a second coupling part 290 disposed on the inner surface of the fastening body 280 (or a second screw thread, or a cap screw thread, or It may further include a cap coupling member, or a second coupling means, or a second coupling structure, or a second coupling element).

The cap ceiling portion 210 may form the upper surface of the sample container 10. The cap ceiling portion 210 may have a substantially circular shape. Additionally, the cap wall portion 230 may have a substantially circular pillar shape. The top of the cap wall portion 230 may be closed by the cap ceiling portion 210. The cab wall portion 230 may form a concave receiving space together with the cap ceiling portion 210. A liquid substance, such as a preservative solution, may be accommodated in the space surrounded by the cap wall portion 230 and the cap ceiling portion 210. The lower portion of the cap wall portion 230 may have an open shape. And, as will be described later, the lower end of the cap wall 230 is coupled to the stopper 300, and the preservative solution is sealed and accommodated in the space surrounded by the cap ceiling 210, the cap wall 230, and the stopper 300. You can.

In some embodiments, the width (e.g., outer diameter) of the outer peripheral surface of the cap wall portion 230 is smaller than the width (e.g., inner diameter) of the inner peripheral surface of the main body wall portion 130, and the container body 100 and the container cap 200 In this coupled state, the cap wall portion 230 can be inserted into the container body 100.

The fastening body portion 280 may have a substantially circular pillar shape. The fastening body portion 280 may be configured to provide a space in which the second coupling portion 290 for coupling to the container body 100 is disposed. The fastening body portion 280 may have a shape that protrudes downward from the edge of the cap ceiling portion 210. Accordingly, from a plan view, the fastening body portion 280 may have a shape surrounding the cap wall portion 230. The length at which the fastening body portion 280 protrudes downward from the cap ceiling portion 210 may be smaller than the length at which the cap wall portion 230 protrudes downward. That is, the length of the fastening body portion 280 in the third direction (Z) may be smaller than the length of the cap wall portion 230 in the third direction (Z). The fastening body portion 280 and the cap wall portion 230 may be spaced apart in the horizontal direction. In a state where the container body 100 and the container cap 200 are at least partially coupled, the body wall portion 130 of the container body 100 is spaced horizontally between the fastening body portion 280 and the cap wall portion 230. Can be inserted into space.

A second coupling portion 290 may be disposed on the inner surface, that is, the inner peripheral surface, of the fastening body portion 280. The second coupling part 290 may include still threads and have an inclination capable of being coupled to the first coupling part 190. That is, the second coupling portion 290 may have a shape corresponding to the first coupling portion 190, that is, it may be provided as a pair. Through the above-described structure, the first coupling portion 190 protruding outward from the main body wall portion 130 and the second coupling portion 290 protruding inward from the fastening body portion 280 face each other and are tightened with screws. A bond structure can be formed.

One or more blocking protrusions 250 (or shielding portions, or passage shielding portions, or passage shielding protrusions) may be disposed at the bottom of the cap wall portion 230. The blocking protrusion 250 may be configured to seal or open the third passage opening 350p of the stopper partition 350 of the stopper 300, which will be described later. The lower or lower surface of the cap wall portion 230 has a planar ring shape, and the blocking protrusion 250 may protrude downward from the lower surface of the cap wall portion 230. The blocking protrusion 250 may have a substantially circular arc shape in plan view. As a non-limiting example, four blocking protrusions 250 may be provided in a rotational or circular arrangement at an angle of about 90° based on the center of the plane of the cap ceiling 210.

When a plurality of blocking protrusions 250 are provided, a second passage opening 250p (or a separation space, a separation portion, or a passage portion) may be formed between the blocking protrusions 250 that are closest to each other. When four blocking protrusions 250 are provided, four second passage openings 250p may also be defined. In another embodiment, when only one blocking protrusion 250 is provided, one side and the other side of the blocking protrusion 250, which has a circular arc shape in plan, are spaced apart from each other, and a space between the one side and the other side is provided. The second passage opening may be defined by. In this case, there may be one second passage opening.

As described above, the blocking protrusion 250 and the second passage opening 250p formed or defined by the blocking protrusion 250 are the stopper partition 350 of the stopper 300 and its third passage opening 350p, which will be described later. Depending on the state of alignment, a path or passage through which the preservation solution flows can be provided or sealed. That is, the internal space can be sealed or opened depending on the relative degree of rotation between the container cap 200 and the stopper 300. To this end, the blocking protrusion 250 and the second passage opening 250p must have an appropriate shape and size to seal or open the third passage opening 350p.

In an exemplary embodiment, the horizontal length L250 of the blocking protrusion 250 may be greater than the length L350p of the third passage opening 350p of the stopper 300. For example, the lower limit of the length L250 of the blocking protrusion 250 may be about 45° or more, or about 50° or more, or about 60° or more, or about 70° or more. In this specification, the length of the components such as the blocking protrusion 250, the second passage opening 250p, and the third passage opening 350p is the center of the planar center when they are circularly arranged and have the shape of a circle or arc. It can be explained as a central angle based on . This is because when a component has the shape of a circle or arc, the actual length in the circumferential direction is proportional to the central angle of the circle or arc. In other words, the length of circularly arranged or arc-shaped components can be expressed as a central angle and understood as the length in the circumferential direction, unless otherwise defined.

The upper limit of the length L250 of the blocking protrusion 250 may be determined depending on the number of blocking protrusions 250, etc. The upper limit of the length L250 of the blocking protrusion 250 is not particularly limited, but may be about 340° when there is only one blocking protrusion 250. Alternatively, when two blocking protrusions 250 are provided, the angle may be about 160°. Alternatively, when three blocking protrusions 250 are provided, the angle may be about 100°. Alternatively, when four blocking protrusions 250 are provided as shown in the drawing, the angle may be about 80°, or about 75°.

Meanwhile, the lower limit of the horizontal length L250p of the second passage opening 250p may be about 15° or more, about 18° or more, or about 20° or more. For example, the length L250p of the second passage opening 250p may be smaller than the length L250 of the blocking protrusion 250. The upper limit of the length L250p of the second passage opening 250p is not particularly limited, but may be about 30° or less, or about 25° or less. As a non-limiting example, the length of the second passage opening 250p may be substantially the same as the length of the third passage opening 350p, or within a range of about ±10%, or within a range of about ±5%. However, the present invention is not limited to this, and the length (L350p) of the third passage opening (350p) may be greater than the length (L250p) of the second passage opening (250p).

The above-described cap ceiling portion 210, cap wall portion 230, fastening body portion 280, second coupling portion 290, and blocking protrusion 250 may be formed integrally with each other without physical boundaries, but the present invention It is not limited to this.

The stopper 300 (or sealing cap, or preservative solution sealing means, or preservative solution plugging means) may have an open top. The stopper 300 may be configured to cover the lower opening formed by the cap wall portion 230 of the container cap 200 to seal or open the space in which the preservative liquid is accommodated.

The stopper 300 includes a stopper bottom 310, a stopper wall 330 protruding upward from the edge of the stopper bottom 310, and a stopper partition 350 protruding upward from the stopper bottom 310. It can be included.

The stopper bottom 310 may be approximately circular in shape. The stopper bottom portion 310 may face the cap ceiling portion 210 and be spaced apart from each other in the third direction (Z). The bottom of the stopper 310 may have a hole 310h. The hole 310h may have a substantially circular arc shape in plan, but the present invention is not limited thereto. The maximum length of the hole 310h in the circumferential direction may be smaller than the length L250 of the blocking protrusion 250. The hole 310h may function as a fluid path through which the preservative liquid contained in the internal space formed by the container cap 200 and the stopper 300 flows down and flows into the container body 100. As a non-limiting example, four holes 310h may be provided in a circular arrangement or a rotational arrangement at an angle of about 90° based on the planar center of the stopper bottom 310.

The stopper wall portion 330 may have a substantially circular pillar shape. The lower end of the stopper wall part 330 may be closed by the stopper bottom part 310. The stopper wall portion 330 may form a coupling structure with the cap wall portion 230 of the container cap 200. For example, the cap wall portion 330 is press-fitted with the cap wall portion 230, and the cap wall portion 230 is inserted into the cap wall portion 330, and the inner surface of the cap wall portion 330 is It is in close contact with the outer surface of the cap wall portion 230 and can be fitted. To this end, the inner diameter of the stopper wall portion 330 may be larger than the outer diameter of the cap wall portion 230, but the present invention is not limited thereto and may have an appropriate inner diameter to enable interference fit.

The fitting coupling formed by the stopper wall portion 330 and the cap wall portion 230, unlike the above-described screw-fastening coupling, depends on the relative degree of rotation between the stopper 300 and the container cap 200 and the stopper 300 and the container cap. The distance in the third direction (Z) (up and down direction) between 200 may be independent and free. In other words, the relative rotation and linear motion of the stopper 300 and the container cap 200 may not be dependent on each other. As a non-limiting example to explain the fitting, in a state in which the rotation of the stopper 300 is fixed, the cap 200 maintains its height without moving in the vertical direction, and only the cap 200 may rotate. . For another non-limiting example, while the height of the stopper 300 is fixed, the cap 200 may not rotate and only the cap 200 may move in the vertical direction. For another non-limiting example, in a state in which the rotation of the stopper 300 is fixed, the cap 200 rotates a first rotation degree (e.g., 180°) and the cap 200 moves downward by a first distance. Alternatively, the cap 200 may rotate a second rotation degree (eg, 270°) and the cap 20 may move downward by the first distance.

Although not shown in the drawing, the outer surface of the cap wall part 230 and the inner surface of the stopper wall part 330 have grooves and grooves to stably maintain the mutual fitting state and the initial distance in the third direction (Z) accordingly. A fitting auxiliary structure such as a protrusion may be formed. In an exemplary embodiment, the outer and/or inner surfaces of each of the cap wall portion 230 and the stopper wall portion 330 are provided with a third direction (Z), for example, vertical direction holding structure that can contact or interfere with each other. can be provided. Unless a strong external force or rotation is provided through contact, interference, etc. between the first vertical direction holding structure provided on the cap wall portion 230 and the second vertical direction holding structure provided on the cap wall portion 330. , the distance between the cap 200 and the stopper 300 in the third direction (Z) may be maintained, that is, the relative third direction (Z) positions of the cap 200 and the stopper 300 may be maintained.

When the container body 100 and the container cap 200 are combined, and the container cap 200 and the stopper 300 are combined, the stopper 300 may be located in the inner space of the container body 100. At this time, the outer diameter of the stopper wall 330 of the stopper 300 is smaller than the inner diameter of the main body wall 130 of the container body 100, and the outer peripheral surface of the stopper wall 330 is the inner diameter of the main body wall 130. It can be spaced apart laterally and horizontally.

Additionally, a second stopper 370 may be formed on the outer peripheral surface of the stopper wall portion 330. The second stopper 370 causes interference with the first stopper 170 of the container body 100, and through this, the degree of rotation of the stopper 300 with respect to the container body 100 and the position of the stopper 300 are adjusted. It may be configured to limit the degree of descent in three directions (Z). The drawing illustrates a case where the second stopper 370 is in the form of a groove formed on the outer peripheral surface of the stopper wall portion 330, but the present invention is not limited thereto. A person skilled in the art may, within the scope of the technical idea of the present invention, form the first stopper in the form of a groove and configure the second stopper in the form of a protrusion, or in another form, create a physical barrier between the stopper 300 and the container body 100. It may be transformed into a form that causes interference.

The second stopper 370 (or locking groove) according to this embodiment is formed at the bottom of the stopper wall portion 330, and the depth in the third direction (Z) increases as it goes in one direction, and the stopper surface 370s increases. May include exposed structures. The second stopper 370 is formed at the bottom of the outer peripheral surface of the stopper wall portion 330, and may be a groove indented in the inner direction on the plane of the stopper 300 and from the bottom towards the upper side in the third direction (Z). The groove recessed from the outer peripheral surface of the stopper wall portion 330 provides an inclined surface 370a, which is a step located on the third direction (Z) side, and a planar space to which the third direction (Z) belongs, which is a step located on the side. A stopper surface (370s) can be provided. Figure 5 and the like illustrate a case where four second stoppers 370 are provided and they are arranged adjacent to each other. That is, the planar shape of the second stopper 370 is approximately arc-shaped, and the center angle of the arc may be within a range of approximately 90°, for example, approximately 90°±5%.

Specifically, as shown in FIGS. 6 and 7, the bottom portion of the stopper 310 is arranged to face downward, that is, the stopper 300 is arranged to be coupled to the container cap 200. , From a plan view, the locking groove 370 may have a shape whose depth increases counterclockwise. Here, the clockwise and counterclockwise directions are based on the state in which the stopper bottom 310 is arranged to face downward. As shown in FIG. 7, the stopper 300 is turned over so that the stopper bottom 310 faces upward. In this state, the clockwise direction in the plane can be understood as the counterclockwise direction.

That is, when the container body 100 is fixed, the stopper bottom 310 of the stopper 300 is placed facing downward, and the stopper 300 is rotated clockwise, the first stopper 170 ( That is, a stopper protrusion) is inserted into the second stopper 370 (or a locking groove, or a stopper groove), and the first stopper 170 can advance according to the change in depth of the second stopper 370. And after rotating to a predetermined degree, the side of the first stopper 170 may be configured to come into close contact with the stopper surface 370s of the second stopper 370 and further rotation may be restricted.

In other words, when the stopper 300 is press-fitted to the container cap 200 and the container cap 200 and the container body 100 are screwed together, the stopper 300 and the container body 100 are screwed together. Depending on the tightening state, it may have a predetermined arrangement state.

At this time, in a state in which the container cap 200 and the container body 100 are sufficiently screwed together, the first stopper 170 (i.e., post) of the container body 100 is connected to any one of the stoppers 300. 2 It may be at least partially inserted into the stopper 370 (i.e., the locking groove). If the first stopper 170 is inserted at a position where the depth of the second stopper 370 is small, the upper surface of the first stopper 170 (i.e., post) and the inclined surface 370a of the second stopper 370 is in contact with each other, and the upper surface of the first stopper 170 and the inclined surface of the second stopper 370 may function as a stopper to prevent the stopper 300 from descending in the third direction (Z) (e.g., in the first state ).

And when the container cap 200 is further rotated clockwise with respect to the container body 100, the stopper 300 press-fitted with the container cap 200 is, with respect to the container body 100, the container cap ( 200) can rotate clockwise. At this time, if it is understood that the container body 100 is in a fixed state, that is, the position of the first stopper 170 is fixed, the second stopper 370 rotates clockwise, and the first stopper 170 and In terms of the relative positions between the second stoppers 370, it may be understood that the first stopper 170 inserted into the second stopper 370 moves counterclockwise. That is, the side of the first stopper 170 may gradually become closer to the stopper surface 370s of the second stopper 370 structure.

Furthermore, as the second stopper 370 has a shape in which the indentation depth in the third direction (Z) becomes deeper as it goes counterclockwise on the plane, the second stopper 370 of the first stopper 170 (i.e., the post) The insertion depth into the (i.e., catching groove) can be larger. Therefore, compared to the above first state, the third direction (Z) positions of the container body 100 and the first stopper 170 are fixed, but as the second stopper 370 moves counterclockwise, the third direction (Z) positions of the container body 100 and the first stopper 170 are fixed. Because the depth in the direction Z is shaped to increase, the stopper 300 may be able to move further downward compared to the first state. That is, in this state (second state), more first stoppers 170 are inserted than in the first state, and the length over which the stopper 300 and the first stopper 170 overlap in the horizontal direction may be greater.

And when the container cap 200 is further rotated clockwise based on the container body 100, the side surface of the first stopper 170 is in contact with the stopper surface 370s of the second stopper 370, and the first stopper 170 is in contact with the stopper surface 370s of the second stopper 370. Further rotation of the stopper 300 may be restricted through interference between the side of 170 and the stopper surface 370s. In other words, even if the container cap 200 is further rotated with respect to the container body 100, the stopper 300 may no longer rotate with respect to the container body 100, and therefore is in an interference-fitted state. In the coupling relationship between the container cap 200 and the stopper 300, only the container cap 200 can rotate with respect to the stopper 300.

Due to the above roughly wedge-shaped second stopper 370 structure and the first stopper 170 of the container body 100 interfering with it, the user can rotate only the container cap 200 with respect to the container body 100. Even in this case, the rotation relationship between the container body 100, the container cap 200, and the stopper 300 is varied, and the rotation relationship between the container body 100 and the stopper 300 is maintained regardless of the rotation state of the container cap 200. The height of the stopper 300 in the third direction (Z) according to the degree of rotation, that is, the relative position of the container body 100 and the stopper 300 in the third direction (Z) can be adjusted.

Meanwhile, the stopper partition 350 (or stopper protrusion) may have a substantially circular pillar shape. The plug partition wall portion 350 protrudes upward from the plug bottom portion 310 and may be surrounded by the plug wall portion 330 in plan view. Accordingly, the inner surface of the stopper wall part 330 and the outer surface of the stopper partition wall part 350 may be spaced apart from each other in the horizontal direction.

When the container cap 200 and the stopper 300 are combined, the cap wall portion 230 and the blocking protrusion 250 of the container cap 200 are connected to the stopper wall portion 330 and the stopper partition wall portion ( 350) can be inserted into the space between them and combined. As described above, the container cap 200 and the closure 300 may be an interference fit in which the outer surface of the cap wall portion 230 of the container cap 200 is in close contact with the inner surface of the closure wall portion 330. Furthermore, the cap partition 350 may be inserted into the cap wall part 230, and the inner surface of the cap wall part 230 may be in close contact with the outer surface of the cap partition 350 and fitted. To this end, the inner diameter of the cap wall portion 230 may be larger than the outer diameter of the stopper partition 350, but the present invention is not limited thereto and may have an appropriate inner diameter that allows interference fit.

In addition, the hole 310h of the above-mentioned stopper bottom 310 is located only in the space between the stopper partition 350 and the stopper wall part 330, and the stopper partition wall portion ( 350) may not exist in the inner space. The space of the stopper bottom part 310 surrounded by the stopper partition 350 may not have any space for fluid to pass through. The maximum protrusion length of the stopper partition 350 in the third direction (Z) may be smaller than the protrusion length of the stopper wall part 330 in the third direction (Z). That is, the height of the top of the stopper partition 350 may be lower than the height of the top of the stopper wall part 330.

As described above, the stopper partition 350 has a substantially circular pillar shape, and its upper surface has a shape with heights, that is, the upper surface of the stopper partition 350, which is approximately annular in plan, is partially oriented in the third direction (Z). ) It may have a shape that is indented or depressed toward the bottom. The indented portion may be defined as a third passage opening 350p. The shape of the stopper partition 350 is understood as a shape in which protrusions are more protruding on the upper side of the shape of a complete ring pillar, or the first partition 351 (or the first part, or the first partition 351) having different heights. 1 protrusion) and the second partition wall portion 352 (or the second portion, or the second protrusion) may be understood as being alternately arranged in a circular manner.

For example, the stopper partition 350 includes a first partition 351 (or first portion) having a first height H1 and a second height H2 smaller than the first height H1. 2 may include a partition wall portion 352 (or a second portion). The first partition walls 351 and the second partition walls 352 may be arranged in an alternating circular manner and may be in close contact with each other. As a non-limiting example, the first partition wall portion 351 and the second partition wall portion 352 are each rotated or circularly arranged at an angle of about 90° with respect to the planar center of the stopper bottom portion 310, so that there are four of them. can be provided.

When a plurality of first partition walls 351 are provided, a third passage opening 350p (or separation space, or separation part, or passage part) will be formed between the first partition walls 351 that are closest to each other. You can. When four first partition walls 351 are provided, four third passage openings 350p and four second partition walls 352 may also be defined. An approximately U-shaped space surrounded by the side surfaces of the two first partition walls 351 that are closest to each other and the top surface of one second partition wall part 352 may be defined as the third passage opening 350p. . In another embodiment, only one first partition wall portion 351 may be provided, and in this case, one side and the other side of the first partition wall portion 351, which has a circular arc shape in plan, are spaced apart from each other, A third passage opening may be defined between one side and the other side. In this case, there may be one second partition wall portion 352 and one third passage opening. As a non-limiting example, as will be described later, the third passage opening 350p and the hole 310h are aligned in a predetermined relationship, and the third passage opening 350p (i.e., the second partition 352) The number of holes 310h may be provided the same.

In an exemplary embodiment, the length L350p of the third passage opening 350p (or the length of the second partition 352) may be smaller than the length L250 of the blocking protrusion 250. For example, the upper limit of the length L350p of the third passage opening 350p is less than about 70°, or less than/about 60°, or less than/about 50°, or less than/about 45°, or about It may be below/below 40°, or below/below about 35°. The lower limit of the length L350p of the third passage opening 350p is not particularly limited, but may be about 15° or more, about 18° or more, or about 20° or more for smooth flow of the preservation liquid.

Meanwhile, the lower limit of the length L351 of the first partition 351 may be about 45° or more, about 50° or more, about 60° or more, or about 70° or more. The upper limit of the length L351 of the first partition 351 may be determined depending on the number of the first partition 351 and the second partition 352, etc. The upper limit of the length L351 of the first partition 351 is not particularly limited, but may be about 340° when there is only one first partition 351. Alternatively, when two first partition walls 351 are provided, the angle may be about 160°. Alternatively, when there are three first partition walls 351, the angle may be about 100°. Alternatively, when there are four first partition walls 351 as shown in the drawing, the angle may be about 80°, or about 75°. Meanwhile, the number of third passage openings 350p of the stopper 300 may be greater than or equal to the number of second passage openings 250p of the container cap 200.

In an exemplary embodiment, the difference between the first height H1 and the second height H2 of the first partition wall portion 351 and the second partition wall portion 352, that is, the third height H2 of the third passage opening 350p The length in the direction (Z) may be in a predetermined relationship with the protrusion length (H250) of the blocking protrusion 250 in the third direction (Z). The difference between the first height H1 and the second height H2 may be smaller than or substantially equal to the protrusion length H250 of the blocking protrusion 250.

Additionally, from a plan view, the second partition wall portion 352 (or the third passage opening 350p) may be aligned with the hole 310h in the radial direction. That is, from a plan view, the virtual reference line extending in the radial direction from the center of the stopper bottom 310 and passing through the second partition 352 (or the third passage opening 350p) is the hole 310h. can pass at least partially.

The separation distance between the most adjacent holes 310h among the holes 310h formed in the bottom of the stopper 310 may be substantially equal to or greater than the length L250 of the blocking protrusion 250 of the container cap 200. there is.

The present invention is not limited to this, but if, unlike the present embodiment, the stopper partition 350 has a third passage opening, but does not have a second partition of a relatively small second height H2, only the plug partition 350 is spaced apart from each other. When it is made up of only the first partition wall portion and the space between the first partition walls is defined as the third passage opening, that is, when the lower end of the third passage opening is defined by the stopper bottom portion 310, it is blocked from the first partition wall portion. Despite the alignment between the protrusions 250, the liquid preservative cannot be completely sealed due to the fine gap formed between the blocking protrusions 250 and the bottom of the stopper 310. In addition, as will be described later, in the initial state, the lowermost end of the container cap 200, for example, the bottom of the blocking protrusion 250, and the stopper bottom 310 of the stopper 300, which are coupled to seal the preservative solution accommodation space, are separated by a predetermined distance. (D) Must be separated. However, if the second partition 352 is omitted, the preservation liquid cannot be completely sealed due to the separation. In other words, the second partition wall may be necessary to secure the separation distance.

Hereinafter, the use of the sample container 10 according to this embodiment and the operational effects due to the arrangement and arrangement between components will be described.

Figures 9 to 12 are cross-sectional perspective views showing the state in which the sample container is used. Specifically, Figure 9 shows the container body 100 and the container cap 200 being disassembled to introduce a sample (not shown) into the container body 100, and the container cap 200 and the stopper 300 are initially combined. This is a diagram showing the state (first state 10a). FIG. 10 is a diagram showing a second state 10b in which the container body 100 and the container cap 200 are at least partially coupled by the first coupling portion 190 and the second coupling portion 290. Figure 11 shows the point at which the coupling by the first coupling part 190 and the second coupling part 290 progresses further compared to Figure 10, and interference by the first stopper 170 and the second stopper 370 occurs. (This is a diagram showing the third state (10c)). FIG. 12 is a diagram illustrating a fourth state 10d in which the coupling by the first coupling portion 190 and the second coupling portion 290 progresses further compared to FIG. 11 and the preservative solution accommodating space is opened.

Additionally, FIGS. 13 to 16 are cross-sectional views showing the state in which the sample container is used in the first state (10a) to the fourth state (10d) of FIGS. 9 to 12, respectively. Figures 17 to 20 are perspective views showing the arrangement of the container cap and sealing stopper in the states of Figures 9 to 12, respectively. Figures 21 to 24 are side projection views showing the arrangement of the container cap and sealing stopper in the states of Figures 9 to 12, respectively.

9 to 20, the container body 100 remains fixed without rotating, and only the container cap 200 and/or stopper 300 rotates. 21 to 24 show a state in which the container cap 200 is rotated while the stopper 300 is fixed.

First, referring further to FIG. 9 and the like, in the first state 10a, the first coupling portion 190 and the second coupling portion 290 of the container body 100 and the container cap 200 do not form mutual coupling. The container body 100 and the container cap 200 can be disassembled. The sample collected in the first state 10a may be put into the container body 100.

Additionally, in the first state 10a, the container cap 200 and the stopper 300 may be coupled, that is, fitted. As described above, the cap wall portion 230 and the blocking protrusion 250 of the container cap 200 are at least partially formed on the inner surface of the closure wall portion 330 and the outer surface of the closure partition wall portion 350 of the closure 300. It is in close contact with and can be inserted between them.

At this time, the lowest end of the container cap 200, for example, the lowest end of the blocking protrusion 250, is inserted between the stopper wall part 330 and the stopper partition 350, and its base surface, for example, the upper surface of the stopper bottom part 310, They may not be in contact but are spaced apart in the third direction (Z) by a predetermined distance (D). Here, the predetermined distance D is the difference between the first height H1 and the second height H2 (i.e., the third direction (Z) length of the third passage opening 350p) and/or the blocking protrusion 250. It may be smaller than the third direction (Z) protrusion length (H250). When the predetermined distance D and the length of the third passage opening 350p and the blocking protrusion 250 in the third direction (Z) are in the above relationship, from the third state 10c to be described later to the fourth state 10d. Modification may be possible.

Additionally, in the first state 10a, the blocking protrusion 250 may be aligned to overlap the third passage opening 350p in the radial direction. That is, the inner surface of the blocking protrusion 250 is in contact with a part of the horizontal edge of the outer surface of the first partition 351 and the upper part of the outer surface of the second partition 352, so that the blocking protrusion 250 is The third passage opening (350p) can be sealed. Additionally, a portion of the lower end of the inner surface of the cap wall portion 230 may be in contact with a portion of the upper portion of the outer surface of the first partition wall portion 351. In other words, an internal space in which the stopper 300 and the container cap 200 are sealed together is formed by aligning the third passage opening 350p of the stopper partition 350 with the blocking protrusion 250 of the container cap 200. It can be configured to form a state in which a preservation solution (not shown) is sealed and contained. Additionally, in the first state 10a, the blocking protrusion 250 may at least partially or completely overlap the hole 310h in the third direction (Z).

Next, referring further to FIG. 10 and the like, after the sample is introduced into the container body 100 in the first state 10a, the container cap 200 and the container body 100 may be at least partially screwed together. That is, the second state 10b is at least partially between the first coupling part 190 and the second coupling part 290 before rotation and lowering restrictions by the first stopper 170 and the second stopper 370 occur. It may mean the point in time when a positive bond was formed.

While coupling from the first state 10a to the second state 10b is in progress using the first coupling portion 190 and the second coupling portion 290, with respect to the container body 100, The container cap 200 and the stopper 300 may rotate clockwise on a horizontal plane and move downward together in the third direction (Z).

Next, referring further to FIG. 11 , the screw-fastening coupling between the container cap 200 and the container body 100 progresses further in the second state 10b, and at some point, a third state 10c may be formed. The third state 10c is a state in which the first coupling portion 190 and the second coupling portion 290 are at least partially coupled, and at the same time, the container body ( This may mean a point in time when the rotation and descent of the stopper 300 is limited based on 100). In other words, while changing from the second state 10b to the third state 10c, with respect to the container body 100, the container cap 200 and the stopper 300 rotate clockwise together and move in the third direction ( Z) can move downward. In other words, from the first state 10a to the third state 10c, the coupling state of the container cap 200 and the stopper 300 does not change, and the rotation degree and third direction (Z) position of the container cap 200 and the stopper 300 do not change. etc., the relative positions can be maintained.

As described above, while changing from the second state 10b to the third state 10c, the first stopper 170 in the shape of a protrusion protruding inward from the main body wall portion 130 of the container body 100 is a stopper. It is inserted into the groove-shaped second stopper 370 formed on the outer surface of the stopper wall portion 330 of (300), and at some moment (i.e., in the third state 10c), the side of the first stopper 170 is 2. It physically interferes with the stopper surface 370s of the stopper 370, and further rotation and descent in the third direction (Z) of the stopper 300 may be restricted.

Next, referring further to FIG. 12 and the like, the screw-fastening coupling between the container cap 200 and the container body 100 may proceed further in the third state 10c. In the third state 10c described above, interference occurs between the first stopper 170 of the container body 100 and the second stopper 370 of the stopper 300, and after the third state 10c, the stopper 300 ) can be further rotated and lowered.

On the other hand, based on the container body 100, the container cap 200 continues to rotate clockwise on the horizontal plane and may make an additional downward movement in the third direction (Z). Accordingly, while reaching from the third state 10c to the fourth state 10d, the relative degree of rotation between the container cap 200 and the stopper 300 changes, and the relative distance in the third direction (Z) may change. . In other words, after the position of the stopper 300 is fixed in the third state 10c, the container cap 200 may further rotate and move downward. Here, the distance by which the container cap 200 moves further downward in the third direction (Z) from the third state 10c to the fourth state 10d may approximately correspond to the predetermined separation distance D described above. Through this, unlike in the first state 10a to the third state 10c, the alignment between the blocking protrusion 250 and the third passage opening 350p is misaligned, and at least a portion of the blocking third passage opening 350p Can be opened without being shielded or blocked by the blocking protrusion 250. That is, the second passage opening 250p formed by the blocking protrusion 250 of the container cap 200 spaced apart from each other and the third passage opening 350p of the stopper partition 350 of the stopper 300 are at least partially in the radial direction. It can be aligned or overlapped and connected. And the preservative liquid flows out through the open gap formed by connecting the second passage opening 250p and the third passage opening 350p, and toward the container body 100 through the hole 310h of the bottom of the stopper 310. It can flow.

In some embodiments, in the fourth state 10d, the lower end of the blocking protrusion 250 may at least partially contact the upper surface of the stopper bottom 310 of the stopper 300. In addition, the blocking protrusion 250 at least partially overlaps the hole 310h of the stopper 300 in the third direction (Z), or the blocking protrusion 250 overlaps the hole 310h and the third direction (Z). Z) can be completely non-overlapping.

Although the above description focuses on the embodiments of the present invention, this is only an example and does not limit the present invention, and those skilled in the art will understand the present invention without departing from the essential characteristics of the embodiments of the present invention. It will be apparent that various modifications and applications not exemplified above are possible.
