Description

[Technical Field]

[0001] The present invention relates to a crushing vessel for analytical and other uses, and more particularly to a lid for the crushing vessel. The crushing container of the present invention is used to crush materials such as samples and hard solid materials placed inside, and is shaken by external force to crush the materials. The present invention also relates to a sealing method for sealing the container body of the crushing container with a lid piece. [Background technology]

[0002] A known crushing method involves placing a sample (material to be crushed) and a hard solid material in a sealed container, and then shaking the container strongly with an external force to crush the sample into small pieces. The disruption means is called ball mill disruption, bead mill disruption, etc., and is widely used for analysis and other purposes. For example, as a pretreatment for obtaining genetic information, a specimen such as a tissue (subject to be disrupted) such as a cell is enclosed in a disruption container together with a disruption medium (solid matter) and a liquid, and an external force is applied to the disruption container to vigorously shake the tissue with the disruption medium.

[0003] The crushing container used in these crushing means is also called a crushing tube, and is composed of a cylindrical container body with one open end and a lid. In all of the prior art crushing tubes, an external thread is formed on the outer periphery of the opening of the container body, while an internal thread is formed on the lid, and the internal thread of the lid is engaged with the external thread of the container body to close the opening of the container body.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-147170 Summary of the Invention [Problem to be solved by the invention]

[0005] In the prior art crushing container, the container body is sealed by placing a lid on each container body. That is, in the conventional technique, the sample and solid objects for crushing, such as balls, beads, or pestles, are placed in the container body, and the lid is placed over the opening of the container body, turned, and screwed on. The solid objects for crushing can be cocoon-shaped. In practical research and investigation, it is rare to crush and analyze only one sample. In most cases, multiple samples or multiple types of samples under different conditions are crushed and analyzed to arrive at the desired conclusion. Therefore, in practice, multiple containers are prepared, samples are placed in them, and then the containers are sealed with lids.The multiple crushing containers are then mounted on a single vibration device, and the multiple containers are shaken at the same time, crushing the samples in the multiple crushing containers at the same time.

[0006] However, with conventional crushing containers, it is necessary to seal each container body by placing a lid on it one by one. As mentioned above, in practice, multiple samples are often crushed for analysis, and the labor required for closing the lid is a significant burden on researchers. SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, the present invention aims to provide a lid member for a crushing container that can reduce the effort required to close the lid. [Means for solving the problem]

[0007] An embodiment for solving the above-mentioned problems is a lid member that seals the opening of the container body of a crushing container, wherein the crushing container has the container body and the lid member, contains the object to be crushed and solid material inside, and is used for shaking the object to be crushed by external force, the lid member for the crushing container having a plurality of lid pieces, the lid pieces being elastic and some or all of which are inserted into the inside of the container body through the opening to seal the opening, and the circumferential surface of the lid piece being elastically fitted tightly against the inner surface of the container body, and the lid member for the crushing container is characterized in that the plurality of lid pieces are connected together at intervals.

[0008] The cover member of the crushing container of this embodiment has a plurality of cover pieces connected at intervals. The lid member of this embodiment has a plurality of lid pieces, and each lid piece is used as a lid to close the opening of the container body. The lid member of the crushing container of this embodiment is basically used as is.

DETAILED DESCRIPTION OF THE INVENTION

[0031] Hereinafter, an embodiment of the present invention will be described. The disruption vessel 1 of this embodiment is used to disrupt tissue, for example, as a pre-processing step for obtaining genetic information. 1 and 4 show a row of eight crushing containers 1. As shown in FIG. 4, each crushing container 1 is composed of a container body 2 and a lid 3. The container body 2 is a member shaped like a small test tube, and is an elongated container having an opening 5. That is, the crushing container 1 has a bottom wall 7 and a cylindrical side wall 8, and one end is open. The container body 2 is molded from a known resin such as polypropylene resin, and the container body 2 used in this embodiment is transparent. The inner bottom of the container body 2 has an arc-shaped cross section as shown in Figure 4. It is desirable that the inner bottom of the container body 2 be spherical or have a concave shape close to spherical.

[0032] The lid 3 of the crushing container 1 of this embodiment is composed of a lid piece 11 of a lid member 10. The cover member 10 is made of a relatively soft resin having elasticity, such as rubber or silicone resin. 2 and 3, the lid member 10 is formed by directly connecting a plurality of lid pieces 11. In this embodiment, eight lid pieces 11 are connected. The lid piece 11 has an outer shape that is approximately cylindrical. In this embodiment, the outer surface of the lid piece 11 is slightly tapered, and the outer diameter at the tip end is slightly smaller. The outer diameter of the lid piece 11 in its natural state is slightly larger than the inner diameter of the container body 2. The overall height H of the lid piece 11 is approximately 3 mm to 10 mm. A recess 15 is provided at the tip of the lid piece 11. The innermost portion of the recess 15 has an arc-shaped cross section. It is desirable that the innermost portion of the lid piece 11 has a spherical surface or a concave shape close to that.

[0033] In this embodiment, the upper ends of the lid pieces 11 are connected to each other by a band-like portion 20 . In principle, the lid member 10 of this embodiment is used with the lid pieces 11 connected by the strip portions 20, and the lid pieces 11 are not separated. In other words, the strip portions 20 are not runners used during molding, and are not separated.

[0034] The strip portion 20 spans the eight lid pieces 11 and connects the upper ends 16 of the lid pieces 11 together. That is, the strip portion 20 has an integral portion 25 that is integrated with the upper end 16 of each lid piece 11, and a connecting portion 26 that connects the integral portions 25. The strip portion 20 also has handles 30 at both ends. The handles 30 are tongue-shaped and protrude outward from the lid pieces 11 at both ends.

[0035] In this embodiment, the width and thickness of the band-shaped portion 20 are uniform. In this embodiment, the width W of the band-shaped portion 20 is smaller than the diameter D of the top of the lid piece 11. A center line CC of the band-shaped portion 20 passes through the center of the lid piece 11. That is, as shown in Figure 3(a), the band-shaped portion 20 passes through the center of the lid piece 11 when the lid member 10 is viewed in plan view. As described above, the upper ends 16 of the lid pieces 11 are connected to each other by the band-shaped portions 20, and the thickness of the band-shaped portions 20 is uniform. Therefore, when the lid member 10 is viewed from the front, as shown in Figures 3(b) and (d), the integral portions 25 of the band-shaped portions 20 protrude upward from the upper ends 16 of the lid pieces 11.

[0036] In this embodiment, eight crushing containers 1 constitute a crushing container group 50. That is, in this embodiment, one lid member 10 corresponds to eight container bodies 2, and the lid piece 11 of one lid member 10 is inserted into the opening 5 of each container body 2 to function as the lid 3.

[0037] In this embodiment, when inserting the lid piece 11 into the opening 5 of the container body 2, a holding member 60 shown in FIG. 5 and a pressing tool 61 shown in FIG. 6(b) are used as auxiliary tools. The holding member 60 is a stand that can hold a plurality of container bodies 2 shown in FIG. 5(b) and FIG. 6 in an upright position. The holding member 60 employed in this embodiment is a base having a rectangular planar shape, and is provided with a plurality of container holding portions 63 for holding the container body 2. The container holding portions 63 are vertical holes into which the container body 2 is inserted. The holding member 60 has container holding portions 63 arranged in a matrix. In this embodiment, there are eight container holding portions 63 in one row, and 12 rows are provided. Therefore, in this embodiment, the holding member 60 has 96 holes for the container holding portions 63. The spacing between the eight container holding portions 63 in one row is equal to the spacing between the eight lid pieces 11 of the lid member 10. The number of lid pieces 11 of the lid member 10 and their spacing are equal to the number of container holding portions 63 in one row of the holding member 60 and their spacing. The pressing device 61 is a hand-held roller.

[0038] Next, a method for sealing the container body 2 by attaching the lid piece 11 to the container body 2 will be described with reference to FIG. In this embodiment, as shown in FIG. 6, the container body 2 contains tissue as the object to be crushed 100, a hard solid material 101 for crushing the object to be crushed 100, and a liquid for eluting genetic material. The solid object 101 is a crushing medium made of ceramic such as zirconia, natural stone, or metal such as stainless steel, and is hard and wear-resistant. The solid object 101 may be spherical or rod-shaped. The solid object 101 used in this embodiment is cocoon-shaped. That is, the solid object 101 is a rod with approximately spherical ends, and its cross-sectional shape is like that of an athletics track. The number of solids 101 may be one or many. In this embodiment, one cocoon-shaped solid is placed in the container body 2.

[0039] In this embodiment, the container bodies 2 containing the crushable materials 100 and solid materials 101 therein are inserted into the container holding portions 63 of the holding member 60, and the container bodies 2 are arranged in a matrix in an upright position. 6(a), the lid members 10 are placed on the row of container bodies 2. Then, as shown in FIG. 6(b), the tips of the lid pieces 11 are aligned with the openings 5 ​​of the respective container bodies 2. Next, as shown in FIG. 6(b), a hand-held roller as a pressing tool 61 is pressed against the lid member 10, The cover member 10 is pressed downward.

[0040] In the lid member 10 of this embodiment, a band-shaped portion 20 is provided on the lid piece 11, and an integral portion 25 of the band-shaped portion 20 protrudes upward from the upper end 16 of the lid piece 11. The width of the band-shaped portion 20 is uniform and is smaller than the diameter D of the top of the lid piece 11. Therefore, when the lid member 10 is viewed from above, there is a straight line formed by the band-shaped portion 20. The worker rolls the roller along the line of the band-shaped portion 20. As a result, the lid piece 11 moves downward and is pushed into the opening 5 of the container body 2.

[0041] Furthermore, since the center line CC of the belt-like portion 20 passes through the center of the lid piece 11, the pressing force of the roller is transmitted straight to the center of the lid piece 11, and the lid piece 11 moves straight down vertically and enters the opening 5 of the container body 2. The outer diameter of the lid piece 11 in its natural state is slightly larger than the inner diameter of the container body 2. However, because the lid piece 11 is soft and elastic, it contracts in diameter when pressed and enters the opening 5 of the container body 2. The lid piece 11 closes the opening 5 of the container body 2, and its peripheral surface tightly contacts the inner surface of the container body 2 due to its elasticity. This operation is repeated in order until all of the twelve rows of container bodies 2 held by the holding members 60 are sealed. 5(b) shows a state in which 12 crushing container groups 50 are attached to the holding member 60. In this embodiment, the width of the belt-shaped portion 20 is smaller than the diameter D of the top of the lid piece 11, so the belt-shaped portion 20 does not protrude laterally and does not interfere with the adjacent crushing container groups 50. Then, the holding member 60 is introduced as it is into a vibration device (not shown) and is vigorously shaken to crush the object to be crushed 100 inside.

[0042] After shaking for a certain period of time, the holding member 60 is removed from the vibration device (not shown). Then, the handle portion 30 of the lid member 10 attached to the container body 2 as shown in Figure 7(a) is picked up with a hand (not shown), and the lid member 10 is peeled off as shown in Figures 7(b) and (c). As a result, the lid pieces 11 are removed from all of the container bodies 2. Since the center line CC of the belt-like part 20 passes through the center of the lid piece 11, the peeling force is transmitted straight to the center of the lid piece 11, and the lid piece 11 moves straight vertically upward and comes out of the opening 5 of the container body 2.

[0043] In this manner, in this embodiment, by using the cover member 10 and the holding member 60 as a crushing set, the cover 3 (cover piece 11) can be attached and detached efficiently. In the embodiment described above, the number and spacing of the lid pieces 11 of the lid member 10 are equal to the number and spacing of the container holding portions 63 in one row of the holding member 60, but the number and spacing of the lid pieces 11 of the lid member 10 may also be equal to the number and spacing of the container holding portions 63 in one row of the holding member 60. In other words, the number of lid pieces 11 of the lid member 10 may be 12.

[0044] In the above-described lid member 10, the lid pieces 11 are arranged in a single row, but they may be arranged in multiple rows. That is, the multiple lid pieces 11 may be distributed in a plane. The lid member 70 shown in Figure 8 has 96 lid pieces 11 arranged in a matrix. In this embodiment, there are 8 lid pieces 11 in each row, and 12 rows are provided. Therefore, in this embodiment, the lid member 70 is provided with 96 lid pieces 11. The spacing between adjacent lid pieces 11 is equal to the spacing between the container holding portions 63 of the holding member 60. [Explanation of symbols]
