Description

Technical Field

[0001] The present invention relates to a container system and a method for storing a sample using the container system. Background Art

[0002] For the purpose of testing, medical treatment, etc., it is usually necessary to collect body fluids / secretions from an object (human, animal or plant), and then use equipment to perform chemical analysis and physical analysis to determine the condition of the object. Generally, the object and the equipment and personnel involved in chemical analysis and physical analysis are in different geographical locations, so the body fluids / secretions need to be stably stored and transferred.

[0003] According to the prior art, body fluids, secretions, etc. need to be mixed with substances that maintain their physical and chemical properties before they can be transferred. There are many containers for collecting body fluids / secretions. Typically, the container includes two separate bottles and a cap.

[0004] Patent document CN101370425B shows a conventional container system according to the prior art. As shown in FIG1 , a cap 2 is provided with an easily pierced membrane 4.

[0101] Next, the inventive concept of the present invention will be described in detail with reference to the accompanying drawings. What is described here is only the preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention on the basis of the preferred embodiment, and the other ways also fall into the scope of the present invention. In the following specific description, directional terms such as "upper", "lower", "inner", "outer", etc. are used with reference to the directions described in the accompanying drawings. The components of the embodiments of the present invention can be placed in a variety of different directions, and the directional terms are used for illustrative purposes and are not restrictive.

[0102] The "substance" stored in the storage chamber in the present disclosure can be a chemical fixative, such as paraformaldehyde, or any substance suitable for maintaining body fluids / secretions, such as a protease inhibitor, an antimicrobial agent, etc. For ease of explanation, the following description of the present disclosure uses "reagent" to represent the substance.

[0103] The biological sample disclosed in the present invention may be a body fluid or secretion, etc. The body fluid may be any substance that can represent the physical signs of an animal and is naturally expressed by the animal, such as saliva, sweat stains, urine or body fluid; the secretion may be the juice secreted by a plant, tissue fluid, etc., or the liquid secreted by a microorganism, etc. For the convenience of explanation, "saliva" is used as an example in the following description, and the container system of the present invention is applicable to any other type of body fluid or secretion.

[0104] The container system for releasably storing a substance provided by the present invention comprises a sample collection container and a substance storage container. Optionally, the container additionally comprises a funnel 130, which is removably connected to the sample collection container. When the substance storage container is sealedly connected to the sample collection container, the substance storage container is configured to store the substance and then release the substance from the substance storage container. In use, when the substance storage container is connected to the sample collection container, the substance stored in the substance storage container is released into the sample collection container.

[0105] According to a particular embodiment of the invention, the substance storage container is adapted to store an agent intended to stabilize, preserve or promote recovery of saliva from a biological sample. According to a related embodiment, the combination of the substance storage container and the sample collection container is adapted for collection of a biological sample from a subject.

[0106] Reference Figure 2-12 , 14, the container system 100 includes a sample collection container 102 and a material storage container 101.

[0107] Sample collection container

[0108] The sample collection container 102 has an opening that allows saliva to enter. According to one embodiment of the present disclosure, Figure 2 , 3 As shown, the sample collection container 102 has a generally cylindrical shape. In another example, the open end of the sample collection container 102 has a larger size than the other end, and the open end is thus formed similar to Fig.14 The sample collection container 102 can be in various shapes, which can be determined according to the needs, preferences or applications of the user. For example, the lower part of the sample collection container 102 is a polygonal column, and the upper part is formed as a cylindrical opening.

[0109] The sample collection container 102 has a chamber inside for receiving saliva and the like. The sample collection container 102 is preferably made of glass or other transparent materials, and a scale can be set on the wall to confirm the saliva entering the chamber and the dosage of the reagent. In addition, for embodiments using non-transparent reagents or reagents mixed with saliva to produce non-transparent substances, it is obvious that the sample collection container 102 made of transparent material also helps the user to observe whether the saliva and the reagent are evenly mixed. In addition, the sample collection container 102 can also be made of opaque materials, which are particularly suitable for storing photosensitive compositions.

[0110] The sample collection container 102 is provided with a joint member on the outer wall surface of the opening portion thereof for joining the substance storage container 101 and the funnel 130 (if any). Figure 3 , 14In the example of FIG. 1 , the engagement member is an external threaded portion 115B. In another embodiment, the engagement member may also be an internal threaded portion 115A, in which case the lower end of the inner cover 104 extends downward from the lower end surface of the material storage container 101 (in conjunction with the following and Figure 5 , 6 The engaging member can be any other form that ensures that the inner cover 104 and the sample collection container 102 (described in detail below) are tightly engaged and do not rotate relative to each other. For example, the engaging member is an oblique flange (i.e., a flange with a wall thickness that changes from large to small in the radially outward direction), and a corresponding oblique flange is provided on the corresponding member of the material storage container 101. The two can be tightly buckled together by a clamp.

[0111] According to different purposes, the capacity of the sample collection container 102 can be set to 1 ml, 2 ml, ..., 15 ml, 16 ml, etc.

[0112] Material storage container

[0113] See also Figure 3-9 The substance storage container 101 has a partition 111 located on its inner wall surface, and the partition 111 defines the inner cavity of the substance storage container 101 into an upper chamber located at the upper part and a lower chamber located at the lower part. The upper chamber is formed as a storage cavity for storing reagents, and the partition 111 serves as the bottom wall 111 of the storage cavity. The partition 111 is provided with one or more first through holes 109A (see Figure 5 , 7 ).exist Figure 5 , 7 In the example, the partition 111 has a semicircular first through hole 109A. In another example, the number of the first through holes 109A can be adjusted; the shape of the first through hole 109A can also be adjusted. For example, the number of the first through holes 109A can be set to 2, 3, 4, etc.; the shape of the first through hole 109A can be set to a fan shape, a circle, an arc shape, etc. Under the condition that the reagents stored in the storage cavity are easy to flow out of the first through hole 109A, the number and shape of the first through holes 109A can be determined according to the needs, preferences or applications of the user. For the semicircular first through hole 109A and the second through hole 109B, preferably, the center of each circle coincides with the center of the bottom wall 111.

[0114] According to a specific embodiment, the storage chamber can hold approximately 1 ml to 4 ml of reagent, and the capacity of the storage chamber depends on the amount of reagent required by the user to mix saliva for subsequent electrical, chemical testing or microscopic observation.

[0115] The material storage container 101 is made of plastics such as polypropylene, medium density polyethylene (MDPE), high density polyethylene (HDPE), polyethylene, etc. Desirably, the material storage container 101 is a polypropylene product. The outer surface of the material storage container 101 may also include a marking area that facilitates the user to identify the reagent inside. The outer surface of the material storage container 101 may also include an area for pasting or embossing a logo and / or other markings.

[0116] In one example, the wall 103 (including the partition 111) of the substance storage container 101 defines a configuration having an "H" shape in cross section (see Figure 5-7 ). The outer edge of the wall 103 may be Figure 5-7 The cylindrical shape shown may also be a chimney shape formed by curves, etc. In an alternative example, the material storage container 101 is formed into a multi-prism corresponding to the outer wall surface of the storage cavity, so as to facilitate users to hold, twist and rotate the material storage container 101.

[0117] See also Figure 4-6 as well as Figure 8-9 The substance storage container 101 further includes an inner cover 104, which is rotatably fixed to the lower chamber of the substance storage container 101. According to the present disclosure, the inner cover 104 is used to reliably seal the first through hole 109A to prevent the reagent from flowing out; on the other hand, it is used as a connector to connect the substance storage container 101 and the sample collection container 102.

[0118] The top wall 108 of the inner cover 104 has a second through hole 109B. In an unused state, the second through hole 109B is offset from the first through hole 109A, so that the top wall 108 of the inner cover 104 can seal the bottom wall 111 of the storage cavity. Figure 5 , 7 In the example of 9, the second through hole 109B and the first through hole 109A have substantially the same semicircular cross section, and both are set to 1, which can be achieved by Fig.10 Especially clearly shown.

[0119] The following is further combined Figure 4-9 as well as Figure 10-12 The relationship among the lower chamber, the inner cover 104 and the sample collection container 102 according to the first embodiment of the present disclosure is described.

[0120] The inner wall surface 103 of the lower chamber is provided with first protrusions 120A, 120B and an annular convex strip 112A, and the outer wall surface of the inner cover 104 has second protrusions 110A, 110B that match the first protrusions 120A, 120B and an annular groove 112B that matches the annular convex strip 112A. The first protrusions 120A, 120B are protrusions extending inward along the inner wall surface of the lower chamber, and have a first outer inclined wall 121 and a first blocking feature structure opposite to the first outer inclined wall 121. In this embodiment, the first blocking feature structure is a first vertical wall 122. The first vertical wall 122 extends vertically inward from the inner wall surface of the lower chamber. According to Figure 10-12 In the cross-sectional view of the first protrusions 120A and 120B, the first outer inclined wall 121 and the first vertical wall 122 form a right-angled trapezoidal structure, wherein the top surface of the right-angled trapezoid faces the inner cover 104, and the bottom surface (i.e., the root of the first protrusions 120A and 120B) is located on the inner wall surface of the lower chamber. After the inner cover 104 is installed in the lower chamber, the annular convex strip 112A can press the annular groove 112B so that the bottom wall 111 of the inner cover 104 presses the partition 111 and seals the first through hole 109A.

[0121] In the embodiment where the semicircular first through hole 109A and the second through hole 109B are provided, the first protrusion 120 and the second protrusion 110 are provided at the radially opposite ends of the material storage container 101. One of the second protrusions 110A is configured to have a rectangular cross section, that is, the second blocking feature structure and the third blocking feature structure of the second protrusion 110A are both set as the second vertical wall 124 and the third vertical wall 123 extending vertically outward from the wall surface of the inner cover 104; the other second protrusion 110B is configured to have a cross section substantially the same as that of the first protrusions 120A and 120B, that is, it has a second vertical wall 124 and a guide wall 123'.

[0122] In the embodiment where the engaging member of the opening of the sample collection container 102 is an external thread portion 115B, the lower structure of the inner cover 104 has an internal thread portion 115A that cooperates with the external thread portion 115B. Figure 5 , 6 In the preferred embodiment shown in FIG. 8 , the external thread portion 115B and the internal thread portion 115A are configured as orthogonal thread portions, whereby the inner cover 104 can be screwed onto the sample collection container 102 in a clockwise direction.

[0123] According to the above embodiment of the orthodontic thread portion, the first outer inclined wall 121 of the first protrusion 120A, 120B is located at the front position in the clockwise rotation direction, that is, during the rotation process, the first outer inclined wall 121 first passes over the second protrusion 110A on the inner cover 104.

[0124] It should be noted that, in this article, "front" refers to the front part of a component or part in the rotation direction, and "rear" refers to the rear part of a component or part in the rotation direction. Fig.10 In the container system 100, the material storage container 101 is screwed into the sample collection container 102 clockwise, and the first outer inclined wall 121 on the wall is the "front" wall of the first protrusions 120A and 120B; in contrast, the wall 124 (i.e., the second blocking feature structure, the second vertical wall 124) of the second protrusion 110A on the left side is away from the first protrusion 120A, and the wall 124, 124' (i.e., the second blocking feature structure, the second vertical wall 124, 124', wherein the second vertical wall 124' refers to the second vertical wall 122 of the first protrusion 120B) of the second protrusion 110B on the right side is in contact with the first vertical wall 122 of the first protrusion 120B. Fig.19 ) is the "front" wall; the first vertical wall 122 of the first raised portion is the "rear" wall, and the wall 123 of the second raised portion.

[0125] The following combination Figure 10-12 The working process of the container system 100 according to the preferred embodiment of the present disclosure is described, wherein for the convenience of showing the relative position relationship between the partition 111 and the top wall 108 of the inner cover 104, Figure 10-12 The internal structure of the substance storage container 101 is shown in perspective. The user first puts saliva into the sample collection container 102, and then screws the substance storage container 101 into the sample collection container 102. Fig.10In the first locking state (at this time, the material collection container 101 is not screwed into the sample collection container 102), the root of one side of the first outer inclined wall 121 of the first protrusion 120A on the left side abuts against the third blocking feature structure 123 (third vertical wall) of the second protrusion 110A with a rectangular cross section. The first vertical wall 122 of the first protrusion 120B on the right side abuts against the second vertical wall 124 of the second protrusion 110 having substantially the same shape as the first protrusions 120A and 120B. In the current state, the first through hole 109A and the second through hole 109B are misaligned with each other. The first protrusion 120A and the second protrusion 110A on the left side can form a certain strength of mutual locking relationship, which can prevent the inner cover 104 from quickly rotating counterclockwise relative to the wall surface 103 of the lower chamber to connect the first through hole 109A and the second through hole 109B at the initial moment when the user screws the material storage container 101 clockwise into the sample collection container 102. Obviously, at the initial moment, the inner cover 104 and the sample collection container 102 have not yet formed a close fit relationship. If the first through hole 109A and the second through hole 109B form a communication state at this time (i.e., the release state of the container system 100), the reagent may unexpectedly overflow from the gap between the inner cover 104 and the sample collection container 102 to the outside. According to the first protrusion 120A and the second protrusion 110A on the left side, at the initial moment, the inner cover 104 and the wall surface 103 of the lower chamber remain in a relatively static state. Only when the inner cover 104 and the sample collection container 102 form a relatively tight locking state, the two will rotate relative to each other.

[0126] For the first protrusion 120B and the second protrusion 110B on the right side, the first vertical wall 122 and the second vertical wall 124 of the two are in contact with each other in the current state to form a strong locking relationship. Fig.10 In this state, the inner cover 104 cannot rotate clockwise relative to the wall surface 103 of the lower chamber (that is, the inner wall surface 103 of the lower chamber cannot rotate counterclockwise relative to the inner cover 104).

[0127] After the user continues to rotate the substance storage container 101 clockwise so that the inner cover 104 and the sample collection container 102 form a relatively tight interlocking relationship, the annular convex strip 112A on the wall of the lower chamber will then move with the annular groove 112B of the inner cover 104 as a guide groove by virtue of the fixing effect of the sample collection container 102 on the inner cover 104, and the first outer inclined wall 121 of the first protrusion 120A will pass over the second protrusion 110A. The first through hole 109A and the second through hole 109B begin to be partially connected and enter Fig.11 Status shown.

[0128] The second protrusion 110B on the right side is provided with a guide wall 123' similar to the first outer inclined wall 121 of the first protrusion 120B. The significance of this is that when the first through hole 109A and the second through hole 109B enter a partially connected state ( Fig.11 ), the wall of the lower chamber can slide over the second protrusion 110B on the right side relatively quickly, so that the first through hole 109A and the second through hole 109B are connected by Fig.11 The partially connected state shown enters Fig.12 The fully connected state (that is, the fully released state).

[0129] Preferably, the guide wall 123 ′ and the first outer inclined wall 121 are parallel to each other.

[0130] According to the present disclosure, the inventive concept of configuring the second protruding portion 110B on the right side to have a rectangular cross section that is the same as or similar to the second protruding portion 110A on the left side also belongs to the technical solution that the present disclosure intends to protect.

[0131] exist Fig.12 In the fully released state, the first vertical wall 122 of the first protrusion 120 is completely in contact with the front wall 124 of the second protrusion 110. In the current state, the material storage container 101 is rotated counterclockwise. Fig.12 Due to the mutual locking relationship between the first protrusion 120B and the second protrusion 110A, the inner cover 104 will not rotate relative to the inner wall surface 103 of the lower chamber, and the material storage container 101 can be easily screwed out of the sample collection container 102, which will make it convenient for the experimenter to take out saliva and the like in the sample collection container 102.

[0132] It is understood that in another embodiment, Figure 10-12 The positions of the first protrusion 120 and the second protrusion 110 shown in the figure can be interchanged. Fig.15 shown.

[0133] Understandably, Fig.15 The first protrusions 120A', 120B', the second protrusions 110A', 110B' and Figure 10-12 The first protrusions 120A, 120B and the second protrusions 110A, 110B shown have the same limiting function and limiting mechanism, which will not be described in detail here.

[0134] In the case where the opening of the sample collection container 102 and the wall surface of the inner cover 104 are provided with reverse threaded portions, the first protrusion 120 and the second protrusion 110 can be provided as follows: Fig.18 The style shown, or Fig.18The positions of the first protrusions 120A", 120B" and the second protrusions 110A", 110B" are interchanged.

[0135] exist Figure 5-7 In the embodiment, the wall surface of the "H"-shaped structure of the substance storage container 101 can be formed at one time by a method such as injection molding. The wall surface 103 of the substance storage container 101 forms an opening at the top, and for this reason, according to an embodiment of the present disclosure, the container system 100 is also configured with outer covers 105 and 106. The outer cover has good elasticity, and the user can squeeze it into the upper opening of the substance storage container 101 to close it. It is understandable that the outer cover should be selected from a material that is stable relative to the reagent.

[0136] In order to form a good sealing effect, the upper inner wall surface of the material storage container 101 and the corresponding position of the outer cover are formed as follows Figure 6 After the outer cover is assembled to the wall of the material storage container 101, even if the inner wall surface 103 of the material storage container 101 and the outer cover are at different horizontal positions (refer to Figure 6 The step groove 116 forms a gap at each horizontal position, and the gap forms a circuitous path, so the reagent is not easy to overflow.

[0137] Optionally, the outer cover is further configured to consist of a closure cover 105 and a cap 106 located on the closure cover 105. The cap 106 preferably surrounds the upper surface of the closure cover 105 and the upper surface of the material storage container 101. After the assembly is completed, the upper edge of the cap 106 and the material storage container 101 form a relatively smooth and continuous surface. In addition, a substance such as an adhesive can be further applied on at least one of the surfaces of the cap 106 and the material storage container 101 facing each other, so that the cap 106 can be adhered to the sample storage container and the upper opening of the material storage container 101 can be more reliably closed.

[0138] According to an embodiment of the present disclosure, a groove is formed at the upper end of the closure cover 105. A protruding first limiting column 113 is formed on the lower surface of the cap 106, and the first limiting column 113 has a shape that matches the groove. The groove and the first limiting column 113 are preferably arranged at the center of their respective components.

[0139] Although the above content, in conjunction with the accompanying drawings, illustrates an embodiment in which the wall 103 of the material storage container 101 is configured as an "H" shape, the wall 103 of the material storage container 101 can also be designed as other types. For example, in the first step, a container is formed by injection molding or the like. The bottom of the container is formed as the outer cover in the above embodiment. Thereafter, the partition 111 (i.e., the bottom wall 111 of the storage cavity) is fixed to the interior of the container by methods such as bonding, heat sealing, etc. Therefore, the above outer cover does not need to be provided in this embodiment.

[0140] Funnel 130

[0141] like Fig.14 As shown, according to one embodiment, the container system 100 can be optionally configured with a funnel 130. The funnel 130 has a structure that is larger at the top and smaller at the bottom, thereby facilitating the placement of saliva and the like into a sample collection container 102 having a relatively small opening. Fig.14 In the embodiment, the lower opening of the funnel 130 may be selectively provided with an internal threaded portion 115A that cooperates with the external threaded portion 115B of the sample collection container 102.

[0142] For example, the cross section of the bottom end of the lower opening of the funnel 130 is set to be smaller than the size of the opening of the sample collection container 102 to ensure that the funnel 130 can be inserted into the sample collection container 102.

[0143] The lower part of the funnel 130 can also be configured to have a slot structure. Specifically, the lower part of the funnel 130 has two concentric annular walls. The outer annular wall can be sleeved on the outer wall surface of the sample collection container 102, and the inner annular wall can be sleeved on the inner wall surface of the sample collection container 102. After the funnel 130 is sleeved on the sample collection container 102, saliva can enter the sample collection container 102 along the inner surface of the inner annular wall.

[0144] Gasket 107

[0145] like Figure 4-6 As shown, according to one embodiment, the container system 100 can be optionally configured with a sealing gasket 107. The sealing gasket 107 has one or more third through holes 109C. The number and shape of the third through holes 109C are preferably set to be the same as the first through holes 109A and the second through holes 109B. Figure 4-Figure 6 In the example, the number of the third through hole 109C is 1 semicircular through hole.

[0146] According to one embodiment of the present disclosure, the sealing gasket 107 is fixed to the top wall 108 of the inner cover 104. In the first embodiment, as shown in FIG. Figure 4As shown, the top wall 108 of the inner cover 104 forms a receiving groove for receiving the sealing gasket 107. The outer edge of the receiving groove is provided with a plurality of limiting bosses 114A extending upward and inward. A plurality of limiting grooves 114B are provided at corresponding positions of the outer edge of the sealing gasket 107. When the top wall 108 of the inner cover 104 presses the bottom wall 111 (i.e., the partition 111) of the storage cavity upward, the sealing gasket 107 is simultaneously pressed toward the bottom wall 111, thereby achieving the effect of blocking the connection between the first through hole 109A and the second through hole 109B.

[0147] In the second embodiment, the top wall 108 of the inner cover 104 forms a receiving groove for receiving the sealing gasket 107. The outer edge of the receiving groove is provided with a plurality of limit grooves extending upward and outward. Fig.16 As shown, a plurality of limiting bosses 116 are provided at corresponding positions on the outer edge of the sealing gasket 107. In the first embodiment, the portion between the limiting grooves in the circumferential direction of the sealing gasket 107 is roughly formed into a petal shape, so that the sealing gasket 107 is formed as shown in FIG. Figure 4 Different from this, in the second embodiment, each of the circumferentially outwardly protruding limiting bosses of the sealing gasket 107 is roughly formed in the shape of petals, so that the sealing gasket 107 is formed as Fig.16 The "petallet" structure shown.

[0148] In the third embodiment, the top wall 108 of the inner cover 104 forms a receiving groove for receiving the sealing gasket 107. The top wall 108 is provided with a plurality of radial ends corresponding to the third through holes 109C. Fig.17 The second limiting post 117 is shown. The second limiting post 117 is inserted into the third through hole 109C.

[0149] When the sealing gasket 107 is mounted on the top wall 108 of the inner cover 104, the third through hole 109C of the sealing gasket 107 is preferably configured to completely overlap with one of the second through hole 109B or the first through hole 109A, and is completely misaligned with the other of the second through hole 109B or the first through hole 109A, as viewed in the vertical direction. In other embodiments, the third through hole 109C may also be configured to be slightly larger than the first through hole 109A and the second through hole 109B. In this case, as viewed in the vertical direction, one of the second through hole 109B or the first through hole 109A is completely surrounded by the third through hole 109C, and the other of the second through hole 109B or the first through hole 109A is misaligned with the third through hole 109C.

[0150] After the sealing gasket 107 is fixed to the corresponding component (the partition 111 or the top wall 108), the third through hole 109C on the sealing gasket 107 is directly connected to the through hole (the first through hole 109A or the second through hole 109B) of the corresponding fixing member. According to the above embodiments, the limiting boss and the limiting column 117 on the top wall 108 of the inner cover 104 can position the sealing gasket 107 to ensure that when the inner cover 104 rotates relative to the inner wall surface 103 of the lower chamber, the sealing gasket 107 rotates synchronously.

[0151] In another embodiment, the sealing pad 107 can also be fixed on the lower surface of the bottom wall 111 of the storage cavity by gluing, hot melting, etc. Similarly, the bottom wall 111 can also be provided with the above-mentioned limiting boss, limiting column 117 and other structures for positioning.

[0152] In other embodiments, the top wall 108 of the inner cover 104 and the bottom wall 111 of the storage cavity may not be provided with corresponding limiting bosses and limiting columns 117, and the sealing gasket 107 is only fixed to the corresponding wall surface by gluing, hot melting or other methods.

[0153] It should be noted that, although the sealing gasket 107 as described above is provided in the preferred embodiment of the present disclosure, in fact, the sealing gasket 107 is only a preferred additional component to prevent the first through hole 109A and the second through hole 109B from being disconnected from each other under normal conditions, and is not a necessary component of the container system 100. In some embodiments, the top wall 108 of the inner cover 104 can directly abut against the bottom wall 111 (partition 111) of the storage cavity to close the first through hole 109A, such as Fig.13 In this embodiment, one or both of the top wall 108 of the inner cover 104 and the bottom wall 111 of the storage cavity are preferably made of elastic material so that a closer fitting relationship is formed between the top wall 108 and the bottom wall 111 .

[0154] Other Alternative Embodiments

[0155] The annular ridge 112A on the inner cover 104 and the annular groove 112B on the lower chamber can be interchanged, that is, the annular ridge 112A is set on the wall surface 103 of the lower chamber, and the annular groove 112B is set on the inner cover 104 .

[0156] In addition, the annular groove 112B on the lower chamber can directly abut against the lower end surface of the inner cover 104 without providing the annular convex strip 112A on the inner cover 104. In this embodiment, preferably, a step groove is provided on the lower end surface of the inner cover 104 to accommodate the annular groove 112B.

[0157] In addition, each annular groove 112B and annular ridge 112A can also be respectively configured as a plurality of dispersed arcuate ridges and arcuate grooves distributed in the circumferential direction. It should be understood that in order to ensure that the inner cover 104 can rotate relative to the wall surface 103 of the lower chamber, the circumferential extension length of each arcuate groove is longer than the circumferential extension length of the arcuate ridge. More preferably, the extension length of one or more of the plurality of arcuate grooves is configured such that when the arcuate ridge abuts against one end face of the arcuate groove in the circumferential direction, the first through hole 109A and the second through hole 109B are not connected to each other; when the arcuate ridge abuts against the other end face of the arcuate groove in the circumferential direction, the first through hole 109A and the second through hole 109B completely overlap in the axial direction. In this embodiment, the arcuate groove of a specific length allows the user to accurately and easily adjust the first through hole 109A and the second through hole 109B to the correct position. Fig.12 fully connected state.

[0158] For the second blocking feature structure, its front wall surface 124 may not necessarily be set as a vertical wall, and it may also be set as Fig.19 Another inclined wall 124' (inner inclined wall) is shown. The acute angle formed by the inclined wall 124' and the tangent line OO' of the inner cover at that location is recorded as θ; the acute angle formed by the guide wall 123 (or the first outer inclined wall 121) and the tangent line of the inner cover at that location is recorded as θ'. θ' is set to be greater than θ, thereby, the second blocking feature structure can form a pawl structure, and the inclined wall 124' thus allows the first protrusion 120B and the second protrusion 110B to form a ratchet structure.

[0159] The first protrusions 120A, 120B and the second protrusions 110A, 110B may not necessarily be arranged in pairs. For example, the number of the second protrusions 110A, 110B may be greater than the number of the first protrusions. Fig.10 The two second protrusions are set to four and are evenly arranged along the circumferential direction. Thus, during the rotation of the inner wall surface 103, the user can feel the feeling of multiple stagnation, thereby adjusting the flow rate of the reagent, etc.

[0160] exist Figure 10-12 In the embodiment of the invention, the inner wall surface 103 cannot rotate counterclockwise relative to the inner cover 104 at the initial moment by the cooperation relationship between the first protrusion 120B and the second protrusion 110B on the right side. Fig.10 Another second protrusion 110B is provided at the left side of the cover 104, and its wall surface 124 is in contact with the wall surface 122, which can also prevent the inner wall surface 103 from rotating counterclockwise relative to the inner cover 104.

[0161] How to use

[0162] according to Figure 2-Figure 17In the embodiment, that is, the engaging members for engaging the inner cover 104 and the sample collection container 102 with each other are orthogonal threads, and the wall surface 103 of the material storage container 101 is configured in an "H" shape, the container system 100 can be used in the following method.

[0163] First, the sealing gasket 107 is placed at the corresponding position of the top wall 108 of the inner cover 104, and then the inner cover 104 is pressed into the lower chamber of the material storage container 101 until the annular groove 112B of the lower chamber is embedded in the annular ridge 112A of the inner cover 104. At this time, the inner cover 104 is pressed against the bottom wall 111 of the storage cavity, and the first through hole 109A is closed.

[0164] Second, the worker or tester injects the required reagent through the upper opening of the "H"-shaped structure and covers the upper opening of the storage chamber with the outer cover.

[0165] Third, the user places saliva directly into the sample collection container 102 or through the funnel 130 .

[0166] Fourth, the user aligns the lower opening of the inner cover 104 with the sample collection container 102 and screws it clockwise onto the sample collection container 102. During this process, the inner cover 104 rotates relative to the wall surface 103 of the lower chamber so that the first through hole 109A, the second through hole 109B, and the third through hole 109C are connected to each other. The reagent in the storage cavity flows into the sample collection container 102.

[0167] It is understandable that the first and second steps can be completed during the production process, and ordinary users can only participate in the third and fourth steps in actual use.

[0168] For the embodiment in which the material storage container 101 is formed by fixing the partition 111 on the vessel, the difference from the above-mentioned method of use is that the above-mentioned first and second steps are changed to the following steps:

[0169] First, invert the material storage container 101 so that the lower opening of the material storage container 101 faces upward;

[0170] Second: inject the reagent through the first through hole 109A, and press the inner cover 104 into the lower chamber of the substance storage container 101 until the annular groove 112B is embedded in the annular convex strip 112A;

[0171] It can be understood that, for the embodiment in which the coupling member for coupling the inner cover 104 and the sample collection container 102 to each other adopts a reverse thread portion, the method of using the container system 100 is different from the above-mentioned methods of use only in that the material storage container 101 is rotated counterclockwise to couple it to the sample collection container 102, which will not be repeated here.

[0172] For embodiments in which the inner cover 104 and the sample collection container 102 are connected to each other using other types of coupling components, those skilled in the art should understand that after the material storage container 101 is connected to the sample collection container 102, the same steps can be used to release the reagent into the sample collection container 102, as well as how to take out samples such as saliva.

[0173] For the embodiment where the first through hole 109A, the second through hole 109B, and the third through hole 109C (if any) are arranged in a fan shape, it can be understood that the spacing of each first protrusion 120 and the second blocking and limiting feature 110 along the circumferential direction will be adjusted accordingly. The angle of the rotation of the material storage container 101 required for the user to adjust the first through hole 109A, the second through hole 109B, and the third through hole 109C (if any) to communicate with each other will be reduced accordingly. The method of using the container system 100 can also be referred to above.

[0174] The protection scope of the present invention is limited only by the claims. With the help of the teachings of the present invention, those skilled in the art will easily recognize that alternative structures of the structures disclosed in the present invention can be used as feasible alternative embodiments, and the embodiments disclosed in the present invention can be combined to generate new embodiments, which also fall within the scope of the appended claims.
