Description

[Technical field]

[0001] The present invention relates to a plastic container with a lid for processing samples in a laboratory and a method for marking the plastic container with a lid when processing samples in a laboratory. Such containers with a lid are also called "reaction vessels" or "micro reaction vessels" when the sample volume is in the microliter range. The containers with a lid are used in scientific and industrial laboratories, especially in the fields of medical, molecular biology and pharmaceutical applications for processing samples. [Background technology]

[0002] In sample processing, covered containers are often marked for clear sample tracking. Due to lack of space and time reasons, the marking is often in the form of a code. This occurs especially when the container is utilized as a "transition container", i.e. for only partial performance of several processing steps. Thus, for such covered containers, often only a simple series of numbers is used, and the complete sample information is recorded in a laboratory log, PC, or otherwise. In multi-step processing, such "transition containers" are often used only for a single work step before the sample is transferred to another container.

[0003] Furthermore, container alignment is important, especially during centrifugation, which is one of the main uses of lidded containers for sample preparation: by knowing as precisely as possible the location of sample components concentrated by centrifugation, users want to minimize losses as much as possible, for example when the supernatant is removed after centrifugation.

[0004] Currently, manual labeling is used for fast and short-term sample marking. It is time-consuming and often suffers from a lack of legibility, as the handwriting is highly individual and often cannot (or is no longer) be read well later or by different people. This poses a risk of sample mix-up. The small amount of space is also a disadvantage, especially in the lids of small-volume lidded containers of 0.5, 1.5 or 2.0 ml, making fast and readable labeling difficult. Marking with label stickers is also time-consuming and often problematic with regard to the adhesion of the sticker to the lidded container.

[0005] EP 2085462 describes a cell culture dish having a cover wall and a ruler, the side wall at the base having first markings in the form of numbers 1 to 12 and the top having second markings in the form of letters. The markings serve to describe the position of the cells on the dish.

[0006] EP 3130659 describes a cell culture vessel with an octagonal prism shape with planes, two opposing surfaces parallel to each other. As a result of those surfaces, suitable cell culture conditions should be created even when the starting number of cells is low. The cell culture vessel should have a scale and markings on the outside of one of the surfaces. The scale should make it possible to estimate by visual inspection the amount of cell medium and the amount of cells in the cell culture vessel, and the markings should allow the distinction of the respective surfaces.

[0007] DE 10 2017 114 251 A1 describes a cell culture bottle having a container for receiving a cell culture medium and a cap attached to the cap neck of the container. The cap is provided with a projection on its outer periphery. The container has reference markings around the cap. The position of the markings relative to the reference markings indicates whether the cap is correctly closed.

[0008] DE 102017009526 A1 describes a container for a liquid with a limited shelf life, comprising a package for receiving the liquid and a closure for closing the package. On the outward surface of the closure and / or on the outer surface of the container, fields are arranged which are each marked with at least one number and which can be individually marked for the purpose of indicating the date on which the package was opened. Each of the fields marked with at least one number is at least partially composed of a paper material and / or plastic suitable for manual marking of the field by scratching and / or scoring.

[0009] U.S. Patent No. 2,739,564 describes a two-part container for medical capsules, pills, and the like, with a dose-time indicating means. To this end, the container has numbers and graduations indicating the time adjacent to the bottle neck, and a closure having an arrow or recess on the collar to align with the numbers and graduations. Conversely, the closure can have the numbers and graduations and the container can have an arrow to align with the numbers and graduations.

[0010] EP 2 449 505 A1 describes a drug container having a cylindrical body and a metal cap mounted thereon. The metal cap has a bar code on the front side, the bar code encircling a central point, whereby the information encoded by the bar code can be read along a closed line encircling the central point. The bar code encodes certain information relating to the contained drug. [Prior art documents] [Patent documents]

[0012] Starting from this, it is an object of the present invention to provide a plastic lidded container for processing samples in a laboratory and a method for marking a plastic lidded container when processing samples in a laboratory, which allows a quicker, clearer and more reliable marking of the samples and processing steps and a more accurate alignment of the lidded container in the laboratory equipment. [Means for solving the problem]

[0013] This object is achieved by a container with a lid having the features of claim 1. Furthermore, this object is achieved by a method with the features of claim 11 and by a method with the features of claim 13. Advantageous embodiments of the container with a lid and of the method are set out in the dependent claims.

[0014] The container with lid according to the invention made of plastic for processing samples in a laboratory comprises: A container having a tubular container body, a container floor at a bottom, a container opening at an upper portion, and a first circumferential seal area at or near the container opening; a lid having a lid base and a circumferential second seal area for sealing against the first seal area; at least one means for releasably attaching the lid to the container when the first sealing area is in sealing contact with the second sealing area; Equipped with The lid, on the upper side, is for marking the alignment of the lidded container in the laboratory apparatus for processing the sample in the lidded container and / or for representing the sample filled in the lidded container Split part and / or to indicate the processing step of the sample in the lidded container. Split part A series of marks extending around the central axis of the container for marking the Split part The present invention is characterized by having the following.

[0015] In a method according to the invention for marking plastic lidded containers when processing samples in a laboratory, a lidded container of the aforementioned type is filled with a sample, a lid is releasably attached to the container, the lidded container is inserted into a laboratory apparatus, A predetermined divided portion among the series of divided portions of the lidded container is aligned with the reference point of the experimental setup, and the Split part The specific conditions selected by the user before or after the covered container is inserted into the laboratory apparatus and / or for multiple processing of samples in different covered containers. Split part The sample is marked before or after being aligned with a reference point of the experimental apparatus, and the sample in the container with lid is processed by the experimental apparatus.

[0016] According to a further method according to the invention for marking plastic lidded containers when processing samples in a laboratory, a lidded container of the aforementioned type is filled with a sample, a lid is releasably attached to the container, and divisions representing the sample filled in the lidded container are marked before or after the sample is filled into the lidded container and / or before or after at least one processing step is performed, and divisions representing the respective processing steps are marked on the upper side of the lid before, after or during the processing step.

[0017] According to the invention, the covered vessel is provided on the upper side of the lid bed with a series of divisions extending around the central axis of the vessel. According to one embodiment, the divisions are graduation lines of a scale and / or numbers, letters, symbols or a combination of the aforementioned indicia. One embodiment is designed, for example, similar to a dial face, either with graduation lines only, numbers only or a combination of graduation lines and numbers. Since the divisions are already present on the lid, the user can clearly mark the sample in the covered vessel by simply and quickly marking the divisions. The user can use this to mark the alignment of the covered vessel in the laboratory apparatus and thereby the effect of the laboratory apparatus on the sample. Furthermore, the user can mark the sample filled in the covered vessel by marking the divisions. Finally, the user can mark the processing steps performed on the sample in the covered vessel by marking the divisions.

[0018] The user can easily and quickly position the covered vessel filled with the sample in any alignment in the laboratory apparatus. This can be the alignment preferred by the user to perform additional processing steps, for example to form a pellet consisting of sample components concentrated in a specific location in the covered vessel by centrifugation, which facilitates the removal of the supernatant by the user. For example, if this is the optimal alignment of the covered vessel, the user can use the "3 o'clock position" as the outside of the covered vessel during centrifugation. In this case, the covered vessel is aligned so that the division that takes the "3 o'clock position" faces outward in the direction of the centrifugal force. Any other alignment can be performed as well without additional labeling. In particular, if the user always selects the same preferred alignment for processing several samples in different covered vessels, the marking of the division selected for this alignment can also be omitted. Furthermore, the user can place the covered vessel in the laboratory apparatus without aligning the division and record the alignment in the laboratory apparatus. For this purpose, the user can, for example, take a picture of the top side of one or more covered vessels in the laboratory apparatus or write down the alignment of each covered vessel. A user may also record the alignment of the lidded container within the selected laboratory apparatus, for example, in one of the methods described above. Additionally, the positioning of one or more lidded containers within the laboratory apparatus may be automatically recorded by a camera.

[0019] The invention allows for easier and faster marking than manual labeling or stickering. The marking is also clearer, since the risk of sample mix-up due to insufficient manual labeling can be avoided. The alignment of the samples in the centrifuge rotor can also be performed in an easier, faster and clearer way. A further advantage is that the embodiment as a dial or similar can be implemented intuitively by the user and without further explanations. The technical implementation can be performed with correspondingly adapted injection molding tools without increasing the production effort.

[0020] According to one embodiment of the invention, the divisions are a series of graduation lines of scales and / or numbers, letters, symbols or a combination of the above-mentioned indicia extending around the central axis of the container. The graduation lines and / or indicia allow for particularly good marking of the alignment of the container. The graduation lines can also be used to mark the sample filled in each case, in particular in that different graduation line positions are assigned to different samples. The positions of the graduation lines can be established in relation to a specific reference position of the container with lid, in particular in relation to a hinge between the lid and the container, a snap connection between the lid and the container or an additional marking on the container or the lid. According to another embodiment, the reference position is a specific division that differs from the other divisions, for example a longer graduation line or a larger number. Preferably, numbers, letters or symbols are used to mark the filled sample or the process step.

[0021] According to another embodiment, the upper side of the lid can be marked in the division by ink or dye or paint or laser beam. For this purpose, the lid of the container can be made of plastic, have a surface texture or have a coating to which the ink, dye or paint adheres well. According to another embodiment, the lid has a greater roughness in the division than in the remaining area of ​​the upper side of the lid. The increased roughness of the division is favorable for permanent marking with ink, dye or paint.

[0022] According to another embodiment, the division is designed on the upper side of the lid with one or more of the following means: a depression on the upper side of the lid, a ridge on the upper side of the lid, a printing on the upper side of the lid, at least one clip clipped to or clipped on the lid, at least one plug element connected to at least one plug structure of the lid, and a number of structural elements of the lid that can be folded or broken. The depression has the advantage of allowing a smooth surface on which the laboratory gloves will not tear. Furthermore, ink, dye or paint can be introduced into the depression, for example by tracing the depression with a felt-tip pen in a manner that is protected from being unintentionally wiped off. The ridge on the upper side of the lid allows marking by completely or partially destroying the ridge, for example by scratching, scraping or removing the ridge by a laser beam. Furthermore, the ridge can also be marked with ink, dye or paint. The printing can be marked by scraping, rubbing or other destruction, or by striking, underlining, circling or other processing with a writing instrument or a laser beam. The clip can be clipped to the lid or clipped on the lid at various positions for marking purposes. The clip is, for example, a clamp or bracket that can be clamped to the edge of the lid or clamped to the opening of the lid. The plug element is, for example, a pin or sleeve that can be selectively plugged into a plug opening at different positions of the lid or into a protruding plug peg. In this case, the plug opening or plug peg is the plug structure of the lid. Furthermore, the plug element can be a disk with divisions that can be clamped into a plug receptacle of the lid at a specific position or multiple different positions. Furthermore, the plug element can be a ring with position marks or multiple divisions that can be plugged into an annular groove on the upper side of the lid at a specific position or various rotational positions or has at least one pin or another plug element on the lower side, which can be plugged into one or more plug openings at a specific position or various positions.Additionally, the division can be formed by a number of structural elements on the top side of the lid, which can be bent, broken or destroyed by hand or, for example, by a writing instrument. The structural elements can be, for example, pegs or small plates (flags) that project vertically upward or radially outward from the lid. Additionally, the structural elements can be bars that extend laterally across one or more grooves on the top side of the lid, which can be destroyed, for example, by a writing instrument.

[0023] According to another embodiment, the bendable or breakable or destructible structure is connected to the lid through a predetermined bend or break point, which is a weakening of the connecting structure provided by design to facilitate bending or breaking of the structural element.

[0024] The depression can be formed in the upper side of the lid by a protuberance on the molding surface of the injection molding tool during injection molding, and / or the protuberance can be formed in the upper side of the lid by a protuberance on the molding surface of the injection molding tool.

[0025] According to another embodiment, the lid has a plug and / or a collar protruding from the underside of the lid base, by means of which the lid can be releasably attached to the tubular container, in which case the lid can be designed with a generally plug-like and / or cap-like shape.

[0026] According to another embodiment, the container with lid is a container with clamped lid or a container with screw-on lid. In the embodiment as a container with clamped lid, the lid is attached to the container by a clamp. The clamping can be performed by a friction connection between the first and second sealing areas. In the embodiment as a container with screw-on lid, the lid and the container have corresponding threads that allow the lid and the container to be screwed together.

[0027] According to another embodiment, the container with lid is a container with a snap lid, in which case the lid and the container have snap elements that allow a snap connection between the lid and the container.

[0028] According to another embodiment, the lid is connected to the container by a hinge. In the case of containers with clamped lids or snap-on lids, the hinge can be integrally connected to the lid and container. In the case of containers with screw-on lids, the hinge can be integrally connected to the lid or container and connected to each other by a ring, allowing the lid to be screwed onto the container.

[0029] According to another embodiment, the first seal area is located on the inner circumference of the container body and the second seal area is located on the outer circumference of the plug. According to another embodiment, the first seal area is located on the upper edge of the container body around the container opening and the second seal area is located on the underside of the lid floor. According to another embodiment, the first seal area is located on the inner circumference of the collar and the second seal area is located on the outer circumference of the container body.

[0030] According to another embodiment, the device for releasably attaching the lid to the container when the first seal area is in sealing contact with the second seal area is a friction connection between the seal area of ​​the lid and the container, and / or a snap connection between the lid and the container, and / or a threaded connection between the lid and the container.

[0031] According to another embodiment, numbers, letters, symbols or a combination of the above mentioned indicia are arranged on the top side of the lid at, on or between the graduation lines of the scale in a continuous manner around the central axis of the container, allowing simple, accurate and unambiguous marking for filled samples and alignment of the lidded container in the laboratory equipment for processing steps.

[0032] According to another embodiment, the indicia are aligned to stand upright when the top of the lid is aligned vertically and the hinge is positioned upright, or when the top of the lid is positioned in another defined alignment, which makes it easy for the user to record and mark the indicia.

[0033] According to another embodiment, the scale is designed such that a scale line is aligned with the center of the hinge or two scale lines are arranged symmetrically on either side of the center of the hinge, in which case the hinge can be used as a reference position for the different scale lines.

[0034] According to another embodiment, the container has at least one marking on its periphery, and the lid can be releasably and sealingly attached to the container with a specific division aligned with the marking. By aligning the division with the marking, the lid is brought into a defined position relative to the container. This is particularly advantageous in the case of screw-on lid containers, clamp-on lid containers or snap-on lid containers, which can be closed in various positions to ensure a defined alignment of the division with the container, and the division can be used for the marking.

[0035] According to another embodiment, the divisions are evenly distributed around the central axis of the container, and preferably there are a total of 4, 10, or 12 divisions.

[0036] In one embodiment of the method according to the invention, a specific division on the lid is aligned with a marking on the container, and then the container with the lid is inserted into the laboratory apparatus and the division is aligned with a reference point on the laboratory apparatus, so that for a container with a lid, where the lid can be attached to the container in different closed positions, the lid can be aligned in a defined alignment with the container.

[0037] According to another embodiment, in at least one recess on the upper side of the lid, ink or dye or paint is introduced or marked by a laser beam, and / or at least one ridge on the upper side of the lid is completely or partially destroyed, and / or at least one printing on the upper side of the lid is marked or completely or partially destroyed by ink or dye or paint or by a laser beam, and / or a division is marked in that a structural element that can be bent or separated is bent or separated.

[Diagram 3] Alternative lids with the same numbers and letters for the lidded container are shown in all main views, in oblique frontal perspective views, and from the side (Figures 3a to 3g). [Figure 4] 4A shows a front view (FIG. 4A), a view from the left side (FIG. 4B), a view from the right side (FIG. 4C), a cross-sectional view (FIG. 4D) along line dd in FIG. 4C, and a plan view (FIG. 4E) of a second lidded container having graduation lines with the lid open. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] In this application, the designations "vertical" and "horizontal," "top" and "bottom," and derived designations such as "upper" and "lower," refer to a covered container with the lid closed, the axis of the tubular container body aligned vertically, and the container floor disposed below the lid floor.

[0041] In an exemplary embodiment, the lidded container has a container 1 having a tubular container body 2 with a container floor 3 at the bottom, a container opening 4 at the top, and a band-shaped circumferential first sealing area 5 on the inner circumference slightly below the container opening 4.

[0042] The container further comprises a lid 6 having a lid floor 7 and a hollow plug 8 protruding from the underside of the lid floor 7. The plug 8 has a circumferential sealing bead 9 on its outer periphery forming a second sealing area 10.

[0043] The lid 6 and the container 1 are integrally connected to each other at their edges via a strip-shaped hinge 11 .

[0044] On the side opposite the hinge 11, the container 1 has a first snap element 12 and the lid 6 has a second snap element 13 of a snap connection 14 between the lid 6 and the container 1. When the first snap element 12 and the second snap element 13 are snapped together, the first sealing area 5 is placed in sealing contact with the second sealing area 10. At the same time, the snap connection 14 is a device 15 for releasably attaching the lid 6 to the container 1.

[0045] A series of circumferential divisions 16 are arranged in each case on the upper side of the lid 6, these divisions being designed, for example, as recesses. The divisions 16 are provided with the numbers 17 from 1 to 9 and with three different symbols 18 (square, circle, triangle), each of which is aligned so as to stand upright when the upper side of the lid 6 is aligned vertically and the hinge 11 is positioned facing upwards.

[0046] In the exemplary embodiment of FIG. 2, the divisions 16 are only designed as numbers 17 from 1 to 12, in a single difference from FIG.

[0047] In the exemplary embodiment of FIG. 3, the divisions 16 are designed as a series of numbers 17 from 1 to 9 and letters 19 from A to C.

[0048] In the exemplary embodiment of Fig. 4, the divisions 16 each comprise linear graduation lines 20 of a scale 21 extending radially with respect to the central axis of the container 1. The graduation lines 20 are arranged such that two graduation lines 20 are symmetrically arranged on either side of the center of the hinge 11. Furthermore, the divisions 16 comprise numbers 17 from 1 to 9 and symbols 18 (square, circle, triangle), each of which is arranged between two adjacent graduation lines 20, as on a clock face.

[0049] The series of numbers 17 begins with the number 1 on hinge 11 and continues clockwise. Symbols 18 are also arranged clockwise around the center of the central axis of container 1, with the last symbol 18 (a triangle) located at the 12 o'clock position.

[0050] One of the divisions 16 can be used in different exemplary embodiments for alignment to a reference point in the laboratory setup. One of the numbers 17 can be used in the exemplary embodiment of Figs. 1-5, one of the symbols 18 in the exemplary embodiment of Figs. 1-4, one of the letters in the exemplary embodiment of Fig. 3 and one of the scale lines 20 in the exemplary embodiment of Fig. 4. The clear arrangement of each scale line 20 between the adjacent numbers 17 or letters 19, respectively, facilitates a clear assignment of the respective scale line 20. Furthermore, the division 16 used in each case for alignment can be marked, for example by tracing with a felt-tip pen. Alternatively, the user uses the same particular selected division 16 for alignment to a reference point when processing different samples in different lidded containers, without marking the selected division 16.

[0051] In particular, the numbers 17, the symbols 18 or the letters 19 can be used to mark the samples received and / or the processing steps carried out, respectively. In the exemplary embodiment of FIG. 2, a specific number 17 can mark a specific sample and / or a specific processing step. In the exemplary embodiment of FIG. 3, a specific number 17 can refer to a processing step and a specific letter 19 can refer to the sample used, or vice versa. The respective indicia 22 (e.g. number 17, letter 19, symbol 18 or combination) can also be marked by tracing with a felt-tip pen. Alternatively, the graduation lines 20 or the indicia 22 can be marked by at least partially destroying it, especially if the graduation lines 20 and the indicia 22 are designed as ridges on the upper side of the lid 6.
