Description

[Technical Field]

[0001] The present disclosure relates to containers, reagent containers and tubes. [Background technology]

[0002] Automated analyzers that analyze blood components and the like are known. Such automated analyzers use reagents contained in containers. The containers containing the reagents are often shaken to homogenize the reagent before being placed in the automated analyzer, or they are moved at high speed by the automated analyzer. This can cause bubbles to form between the liquid reagent and air inside the container. If the dispensing nozzle absorbs or comes into contact with these bubbles, it may not be able to properly absorb the reagent, which can lead to various problems.

[0003] Furthermore, when the automated analyzer moves the container at high speed, the reagent surface sways. If the liquid surface sways, the dispensing nozzle cannot properly draw up the reagent. Therefore, it is necessary to wait for the liquid surface to stop swaying. This waiting time increases the analysis time.

[0004] Therefore, as disclosed in Patent Document 1, for example, it has been proposed to insert a tube into the container and fix it in place. This tube prevents bubbles from entering and the fluctuations in the liquid surface from being transmitted to the tube. This prevents the dispensing nozzle inserted into the tube from absorbing or coming into contact with bubbles, and also eliminates the need to wait for the fluctuations in the liquid surface to subside.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-099769 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the inventors discovered that when a tube is placed inside a container, the effect of surface tension can cause a phenomenon in which the liquid level inside and outside the tube differs. When this phenomenon occurs, the distance the liquid level drops inside the tube when a reagent is drawn into the dispensing nozzle may not correspond to the volume of the drawn reagent. For example, when a reagent is drawn into the dispensing nozzle, the liquid level outside the tube may decrease, but the liquid level inside the tube may remain unchanged. Alternatively, the distance the liquid level drops inside the tube may differ from the distance the liquid level drops outside the tube. When this phenomenon occurs, it becomes impossible to properly position the dispensing nozzle relative to the liquid level, which ultimately makes it impossible for the dispensing nozzle to properly draw in the reagent.

[0007] An object of the present disclosure is to provide a container, a container containing a reagent, and a tube in which the liquid level inside and outside the tube is equal. [Means for solving the problem]

[0008] The container according to the present disclosure comprises a container body for storing a reagent and having an opening on the upper side, and a tube inserted into the container body through the opening and fixed to the container body, the tube having a slit formed therein that penetrates between the inside and outside of the tube and extends in the vertical direction, the slit being formed so that the upper end of the slit is positioned above the height of the liquid surface when a rated capacity of reagent is stored in the container body, and the lower end of the slit is positioned below the height of the liquid surface. When implementing the above-described container, the container body may preferably have a cylindrical mouth that protrudes upward from the top surface of the container body and is continuous around the entire circumference. Also, The upper end of the tube may be cylindrical and continuous around the entire circumference, and may be fixed to the opening when inserted into the opening.

[0009] Furthermore, a container containing a reagent according to the present disclosure includes the container and a reagent stored in the container body.

[0010] Furthermore, the tube disclosed herein is a tube that stores a reagent, is inserted into a container body having an opening on the upper side through the opening, and is fixed to the container body, and the tube has a slit that penetrates between the inside and outside of the tube and extends in the vertical direction, and the slit is formed so that the upper end of the slit is positioned above the height of the liquid level when a rated capacity of reagent is stored in the container body, and the lower end of the slit is positioned below the height of the liquid level.

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the embodiments described below are merely examples, and the present disclosure is not limited to these embodiments.

[0014] First Embodiment 1 is an exploded perspective view of a container 1 according to a first embodiment. The container 1 includes a container body 100 and a pipe 200.

[0015] The container body 100 has an approximately triangular shape with its inner and outer surfaces in a plan view. One of the three sides forming the approximately triangle is an arc. A mouth 101 is formed on the upper side of the container body 100. An opening 102 connecting the inside and outside of the container body 100 is formed in the mouth 101.

[0016] The tube 200 has a circular inner and outer surface in a plan view. An opening 201 is formed at the upper end of the tube 200. A slit 202 is formed in the side of the tube 200, penetrating between the inside and outside of the tube 200 and extending in the vertical direction. The width of the slit 202 is uniform along its entire length. The slit 202 is rectangular in a front view, its vertical length is shorter than that of the tube 200, and its upper and lower ends are closed. Note that in this embodiment, the inner and outer surfaces of the tube 200 have the same shape in a plan view, but in other embodiments, they may have different shapes. Furthermore, the tube 200 is not limited to being cylindrical, and the outer surface may be a rectangular or polygonal tube in a plan view. Furthermore, in this embodiment, the width of the slit 202 is uniform along its entire length, but in other embodiments, the width of the slit 202 may not be uniform along its entire length as long as the object of the present invention is achieved.

[0017] An air vent 203 is formed on the side surface of the tube 200 at a position closer to the opening 201 than the slit 202, penetrating between the inside and outside of the tube 200. Note that the air vent 203 does not necessarily have to be formed.

[0018] The tube 200 is inserted through the opening 102 of the container body 100 and fixed to the container body 100. Specifically, the tube 200 is fixed to the inside of the mouth 101.

[0019] The outer diameter of at least the portion of tube 200 that is inserted into container body 100 is equal to or smaller than the inner diameter of opening 102 formed in mouth 101. Therefore, tube 200 can be easily inserted into container body 100 without deforming it. Furthermore, since there is no need to deform tube 200, the material and dimensions of tube 200 can be determined so as to increase the rigidity of tube 200. Increasing the rigidity of tube 200 can improve the effect of stirring and homogenizing the reagent inside container 1 by shaking container 1.

[0020] Fig. 2 is a vertical cross-sectional view of the container 1. Specifically, Fig. 2 is a vertical cross-sectional view of the container 1 cut along a vertical plane including the perpendicular bisector of the arc of the outer shape of the container body 100.

[0021] A liquid passage hole 204 is formed at the lower end of the tube 200. In the example shown in Fig. 2, the diameter of the liquid passage hole 204 is smaller than the inner diameter of the rest of the tube 200. However, the diameter of the liquid passage hole 204 may be equal to the inner diameter of the rest of the tube 200. Furthermore, the liquid passage hole 204 may be formed at the lowest end of the tube 200, i.e., on the bottom surface, as shown in Fig. 2, or may be formed near the lowest end, i.e., on the side surface of the tube 200, above the lowest end. It is not necessary to form the liquid passage hole 204. The slit 202 may be formed so as to be open at the lower end of the pipe 200, or may be formed so as to communicate with the liquid passage hole 204.

[0022] Liquid reagent 300 is poured into container 1 configured as described above through opening 201, and liquid reagent 300 is stored therein. Alternatively, after liquid reagent 300 is poured through opening 102 of container body 100, tube 200 may be inserted through opening 102 of container body 100 and fixed to container body 100. A cap (not shown) that opens and closes opening 201 can be attached to opening 101. Container 1 and reagent 300 constitute a reagent-filled container.

[0023] The slit 202 is formed so that the slit 202 is positioned at the height of the liquid surface when the rated capacity of the reagent 300 is stored in the container body 100. In other words, the slit 202 is formed so that the upper end of the slit 202 is positioned above the height of the liquid surface when the rated capacity of the reagent 300 is stored in the container body 100. The slit 202 is also formed so that the lower end of the slit 202 is positioned below the height of the liquid surface when the rated capacity of the reagent 300 is stored in the container body 100, and so that the lower end of the slit 202 is positioned below the height of the liquid surface when the reagent 300 has been used to the end.

[0024] Container 1 configured as described above is used as follows. First, to homogenize reagent 300, container 1 is shaken with the cap attached. During this process, due to the presence of tube 200, almost no bubbles are generated inside tube 200. Next, with the cap removed, container 1 is set in an automated analyzer. Furthermore, container 1 is moved at high speed to a position where reagent 300 can be drawn up by a dispensing nozzle. At this time, container 1 moves, for example, along the arc-shaped arrow a1 or the linear arrow a2 in FIG. 1 . During this process, due to the presence of tube 200, almost no bubbles are introduced inside tube 200, and almost no fluctuations in the liquid surface are transmitted to the inside of tube 200. Therefore, the dispensing nozzle inserted through opening 201 can quickly and appropriately draw up reagent 300 after container 1 has been moved.

[0025] Furthermore, the inside and outside of tube 200 are in communication via slit 202, air vent 203, and liquid passage hole 204. Therefore, the liquid level inside and outside tube 200 is equal. Moreover, the liquid level inside and outside tube 200 is continuous via slit 202. In other words, there is no liquid level that is closed inside tube 200. Therefore, when a dispensing nozzle is inserted through opening 201 and a predetermined amount of reagent 300 is sucked up, it is possible to prevent the liquid level inside tube 200 from becoming relatively higher than the liquid level outside tube 200 due to the influence of surface tension generated inside tube 200. In other words, it is possible to maintain the liquid level inside and outside tube 200 at an equal level.

[0026] The width of slit 202 is set to a width that can equalize the liquid level between the inside and outside of tube 200 and prevent bubbles and trembling (waves) on the liquid surface generated outside tube 200 from being transmitted to the inside of tube 200. Specifically, the width of slit 202 is set to preferably 0.1 mm or more and 1.5 mm or less, more preferably 0.3 mm or more and 1.0 mm or less, and even more preferably 0.5 mm.

[0027] The width of slit 202 is uniform throughout its entire length. If the width of slit 202 is assumed to be greater at the bottom, then as reagent 300 is used and the liquid level drops, the width of slit 202 at the height of the liquid level increases. The wider the width of slit 202, the more easily bubbles floating on the liquid surface enter tube 200, and the more easily fluctuations in the liquid level are transmitted to the inside of tube 200. However, the width of slit 202 according to the present disclosure is uniform throughout its entire length. Therefore, regardless of the liquid level, the liquid level can be made equal between the inside and outside of tube 200, and bubbles and liquid level fluctuations (waves) generated outside tube 200 can be prevented from transmitting to the inside of tube 200.

[0028] Furthermore, by positioning and orienting the slit 202 in a specific position and direction, it is possible to more reliably prevent bubbles generated inside the container body 100 from entering the inside of the tube 200. This point will be described below.

[0029] 3 is a cross-sectional view of the container 1 taken along a horizontal plane at a position higher than the liquid level. Bubbles 301 generated inside the container 1 are shown schematically. The bubbles 301 float on the liquid surface and spread out by adhering to the inner surface 103 of the container body 100. Therefore, by positioning the tube 200 and orienting the slit 202 so that the slit 202 is located relatively far from the inner surface 103 of the container body 100, the slit 202 can be kept away from the bubbles 301. Consequently, the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0030] 4 is a cross-sectional view of the container 1 cut on a horizontal plane at a position higher than the liquid level, similar to FIG. 3. However, for the sake of convenience, bubbles 301 are not shown. For example, by attaching a tube 200 to the container body 100 as shown in FIG. 4, the slit 202 can be moved away from the bubbles 301. That is, the center of gravity C of the planar shape of the inner surface 103 of the container body 100 is 100 and the center of gravity C of the planar shape of the outer surface 205 of the tube 200 (assuming that the slit 202 portion is connected and closed). 200 The tube 200 is attached to the container body 100 so that the slits 202 are offset from the center of gravity C 100 The tube 200 is attached to the container body 100 so that the slit 202 faces the side. By attaching the tube 200 to the container body 100 in this manner, the slit 202 can be kept away from the bubbles 301, and therefore, the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0031] In this case, the center of gravity C 100 and center of gravity C 200If the slit 202 is positioned between the centers of gravity (i.e., on the line segment connecting these centers of gravity), the slit 202 can be more reliably kept away from the bubbles 301, and thus the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0032] FIG. 5, like FIG. 3, is a cross-sectional view of the container 1 taken along a horizontal plane at a position higher than the liquid level. However, for ease of explanation, bubbles 301 are not shown. For example, as shown in FIG. 5, by attaching the tube 200 to the container body 100, the slit 202 can be spaced apart from the bubbles 301. That is, the tube 200 is attached to the container body 100 so that the slit 202 is located inside a shape F formed by connecting points at equal predetermined distances from the inner surface 103 of the container body 100 in a plan view. Attaching the tube 200 to the container body 100 in this manner can space the slit 202 away from the bubbles 301, thereby preventing the bubbles 301 from entering the inside of the tube 200 through the slit 202.

[0033] The predetermined distance between shape F and inner surface 103 of container body 100 is preferably greater than the distance from inner surface 103 of container body 100 to the farthest point of bubbles 301 adhering to inner surface 103 of container body 100. After setting the predetermined distance in this manner, by attaching tube 200 to container body 100 so that slit 202 is positioned inside shape F, slit 202 can be more reliably kept away from bubbles 301, and thus bubbles 301 can be prevented from entering the inside of tube 200 through slit 202.

[0034] In addition, the center of gravity C 100 and center of gravity C 200 are offset relative to each other, and the slit 202 is positioned at the center of gravity C 100 The tube 200 may be attached to the container body 100 so that the slit 202 faces the container body 100 side and is positioned inside the shape F. By attaching the tube 200 in this manner, it is possible to more reliably prevent the bubbles 301 from entering the inside of the tube 200 through the slit 202.

[0035] <Second embodiment> 6 is a cross-sectional view of a container 1 according to the second embodiment. The container 1 according to the second embodiment differs from the container 1 according to the first embodiment in the shape of the container body 100. That is, the container body 100 according to the second embodiment has a substantially rectangular parallelepiped shape.

[0036] Although the shape of the container body 100 is different, the container 1 according to the second embodiment includes a tube 200 configured similarly to the tube 200 according to the first embodiment. Therefore, the container 1 according to the second embodiment can also make the liquid level equal between the inside and outside of the tube 200 regardless of the height of the liquid level, and can prevent bubbles and liquid surface tremors (waves) generated outside the tube 200 from being transmitted to the inside of the tube 200.

[0037] Also in the container 1 according to the second embodiment, by setting the installation position of the tube 200 and the orientation of the slit 202 so that the slit 202 is located relatively far from the inner surface 103 of the container body 100, the slit 202 can be kept away from the bubbles 301. Consequently, the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0038] For example, as shown in FIG. 6, the center of gravity C of the planar shape of the inner surface 103 of the container body 100 100 and the center of gravity C of the planar shape of the outer surface 205 of the pipe 200 200 The tube 200 may be attached to the container body 100 so that the slits 202 are offset relative to the center of gravity C 100 The tube 200 may be attached to the container body 100 so that the slit 202 faces the side. By attaching the tube 200 to the container body 100 in this way, even in the container 1 according to the second embodiment, the slit 202 can be kept away from the bubbles 301, and therefore the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0039] 6, for example, the tube 200 may be attached to the container body 100 so that the slit 202 is located inside a shape F formed by connecting points at equal predetermined distances from the inner surface 103 of the container body 100 in a plan view. By attaching the tube 200 to the container body 100 in this way, even in the container 1 according to the second embodiment, the slit 202 can be kept away from the bubbles 301, and therefore the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0040] <Third embodiment> 7 is a cross-sectional view of a container 1 according to a third embodiment. The container 1 according to the third embodiment differs from the container 1 according to the first embodiment in the shape of the container body 100. That is, the container body 100 according to the third embodiment has a substantially cylindrical shape.

[0041] Although the shape of the container body 100 is different, the container 1 according to the third embodiment includes a tube 200 configured similarly to the tube 200 according to the first embodiment. Therefore, the container 1 according to the third embodiment can also make the liquid level equal between the inside and outside of the tube 200 regardless of the height of the liquid level, and can prevent bubbles and liquid surface tremors (waves) generated outside the tube 200 from being transmitted to the inside of the tube 200.

[0042] Also in the container 1 according to the third embodiment, by setting the installation position of the tube 200 and the orientation of the slit 202 so that the slit 202 is located relatively far from the inner surface 103 of the container body 100, the slit 202 can be kept away from the bubbles 301. Consequently, the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0043] For example, as shown in FIG. 7, the center of gravity C of the planar shape of the inner surface 103 of the container body 100 100 and the center of gravity C of the planar shape of the outer surface 205 of the pipe 200 200 The tube 200 may be attached to the container body 100 so that the slits 202 are offset relative to the center of gravity C100 The tube 200 may be attached to the container body 100 so that the slit 202 faces the side. By attaching the tube 200 to the container body 100 in this way, even in the container 1 according to the third embodiment, the slit 202 can be kept away from the bubbles 301, and therefore the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0044] 7, for example, the tube 200 may be attached to the container body 100 so that the slit 202 is located inside a shape F formed by connecting points at equal predetermined distances from the inner surface 103 of the container body 100 in a plan view. By attaching the tube 200 to the container body 100 in this way, even in the container 1 according to the third embodiment, the slit 202 can be kept away from the bubbles 301, and therefore the bubbles 301 can be prevented from entering the inside of the tube 200 through the slit 202.

[0045] <Tube Variations> The pipe 200 provided in the container 1 according to each of the embodiments described so far may be the pipe 200 described below.

[0046] 8A and 8B show front views of various modifications of the tube 200. As shown in FIG. 8A, the slit 202 may be connected to the vent hole 203 at the upper end of the slit 202.

[0047] The tube 200 shown in Fig. 8B does not have a vent hole 203. In addition, the slit 202 extends to near the upper end of the tube 200. That is, the slit 202 shown in Fig. 8B is longer than the slit 202 shown in the first embodiment and the slit 202 shown in Fig. 8A. In this case, the inside and outside of the tube 200 can be communicated via the upper part of the slit 202 instead of the vent hole 203. That is, the air pressure inside and outside the tube 200 can be equalized.

[0048] The tube 200 shown in FIG. 8C has discontinuous slits, i.e., a plurality of slits, i.e., a first slit 202A, a second slit 202B, and a third slit 202C, formed instead of the slit 202. In this case, the first slit 202A may be simply referred to as slit 202A. The first slit 202A, the second slit 202B, and the third slit 202C are aligned in a straight line. In this case, ribs are formed between the first slit 202A and the second slit 202B, and between the second slit 202B and the third slit 202C. This improves the strength of the tube 200 and prevents the shape of the tube 200 and the width of each slit from changing. Although the tube 200 shown in FIG. 8C does not have a vent hole 203, a vent hole 203 may be formed. The number of slits may be two, four, or more.

[0049] The tube 200 shown in FIG. 8D differs from the tube 200 shown in FIG. 8C in that the slits are not aligned in a straight line. The lower ends of the upper slits are positioned lower than the upper ends of the lower slits. Specifically, the second slit 202B is circumferentially offset from the first slit 202A and the third slit 202C. Furthermore, the lower end of the first slit 202A is positioned lower than the upper end of the second slit 202B, and the upper end of the third slit 202C is positioned higher than the lower end of the second slit 202B. In this case, the liquid surface always contacts one of the slits. Therefore, in addition to the reinforcing effect of the ribs, the liquid surface can be reliably maintained between the inside and outside of the tube 200.

[0050] Figure 9 shows a front view of another modified example of the tube 200. The shape of the slit 202 is not limited to the rectangular shape when viewed from the front and extending linearly in the vertical direction as described above, but may be an elongated hole when viewed from the front, or may extend in a curved, serpentine, spiral, or zigzag shape, as shown in Figures 9A, 9B, and 9C. Furthermore, as long as the object of the present invention can be achieved, multiple slits may be formed to extend in parallel.

[0051] FIG. 10 shows cross-sectional views of various further modified examples of tube 200. As illustrated in FIGS. 10A to 10G, tube 200 may have an inner surface shape that has a corner in a plan view. By shaping inner surface 206 of tube 200 into a shape with corner 207 that is convex outward in a plan view, bubbles present inside tube 200 can be concentrated near corner 207, which is located relatively far from the center of tube 200 in a plan view. In other words, even if some of bubble 301 (see FIG. 3) gets inside tube 200, bubble 301 can be prevented from being present near the center of tube 200. Therefore, when a dispensing nozzle is inserted inside tube 200, it is possible to more reliably prevent the dispensing nozzle from coming into contact with bubble 301.

[0052] Furthermore, by forming slit 202 at the position where corner 207 is located, bubbles 301 that have entered the inside of tube 200 through slit 202 can be kept coherent near corner 207, which is located in the same position as slit 202. In other words, bubbles 301 that have entered the inside of tube 200 through slit 202 can be prevented from moving toward the center of tube 200.

[0053] Specifically, the shape of the inner surface of tube 200 may be a regular polygon in plan view, for example, an equilateral triangle as shown in Fig. 10A, a square as shown in Fig. 10B, a regular pentagon as shown in Fig. 10C, or a regular hexagon as shown in Fig. 10D.

[0054] The inner surface of the tube 200 may have a star-like shape in plan view. For example, as shown in Fig. 10E, the inner surface may have five sharp protrusions, or may have three, four, six or more sharp protrusions.

[0055] The inner surface shape of tube 200 may be a shape that combines a circle with a protrusion that protrudes inward or outward from the circle in a plan view. For example, as shown in Fig. 10F, the inner surface shape of tube 200 may be a shape in which protrusions 208 protrude outward from the circle, or as shown in Fig. 10G, the inner surface shape of tube 200 may be a shape in which protrusions 208 protrude inward from the circle.

[0056] <Fourth embodiment> FIG. 11 is a front view of a tube 200 constituting a container 1 according to a fourth embodiment. In the fourth embodiment, the slit 202 is formed so that its upper end is located above the liquid level when a rated volume of reagent 300 is stored in the container body 100. The lower end of the slit 202 is also formed so that it is located below the liquid level in the initial state when the rated volume of reagent 300 is stored in the container body 100. In this case, the lower end of the slit 202 is formed so that it is located above the liquid level when the reagent 300 is used to the end. Therefore, the wall surface of the tube 200 below the lower end of the slit 202 acts as a rib, maintaining strength. The upper end of the slit 202 may be closed or may be open to the upper end of the tube 200 or the air vent 203.

[0057] The tube 200 having the slit 202 is attached to the container body 100, as in the first embodiment, to form the container 1. In this container 1, in the initial state in which the rated volume of reagent 300 is stored, the inside and outside of the tube 200 are in communication via the slit 202, the air vent 203, and the liquid passage 204. Therefore, the liquid level inside and outside the tube 200 is equal. Therefore, the height of the dispensing nozzle inserted into the liquid level in the initial state can be accurately detected. However, if the height of the dispensing nozzle, i.e., the depth to which the dispensing nozzle is inserted into the tube 200, is automatically calculated and controlled after a certain amount of reagent has been used, it is not necessary to maintain the liquid level equal inside and outside the tube 200 until the reagent is used up. The container 1 of this fourth embodiment can be applied to an automatic analyzer that performs such automatic calculations. Furthermore, by minimizing the opening of the slit 202, the intrusion of bubbles into the tube 200 can be suppressed.

[0058] The tubes 200 included in the container 1 described in each embodiment may be prepared separately from the container body 100 and then attached to the container body 100 to form the container 1. Furthermore, the tubes 200 may be replaced with existing tubes (tubes different from the tubes 200 described above) to form the container 1 described in each embodiment. Furthermore, a container containing a reagent may be formed by fixing the tubes 200 to the container body 100 in which the reagent 300 has been stored beforehand. [Industrial Applicability]

[0059] The container and reagent-containing container according to the present disclosure can be used to supply reagents to an automated analyzer. [Explanation of symbols]
