Description

[0001] The invention relates to a sample bottle, in particular a milk sample bottle, according to the preamble of claim 1.

[0002] A similar sample bottle is known as a disposable bottle from DE 603 ​​03 088 T2. background

[0003] The invention relates in particular to a sample bottle (milk sample bottle) which, as a reusable bottle, can be uniquely identified in the process by being equipped with an electronic component within a special holding device. The design of the sample bottle is based on… Fig. 2 as follows: • Bottle body (1), • Bottle cap (2), • Mounting device for an electronic component (3) to protect against hygienic treatment, • Electronic read / write memory component (4) (also called TAG)

[0004] The TAG (4) enables the provision of the desired identification data of the sample as well as the storage and reading of variable product and supplier data and can be used any number of times thanks to the reusable concept of the sample bottle.

[0005] The invention thus relates to an identifiable reusable sample bottle with the aid of an integrated tag in a special holding device, which is suitable for hygienic handling.

[0006] In this document, the term "TAG" is used to refer to an RFID chip in the high-frequency / ultra-high-frequency range, in accordance with the current state of the art. Within the scope of this patent, the term "TAG" is to be used in accordance with the current state of the art and may therefore encompass other frequency ranges and technologies in the future.

[0007] From EP 0 411 274 B1 a sample bottle, in particular a milk sample bottle with the features of the preamble of claim 1, is known, which is made, inter alia, of plastic.

[0008] To improve hygiene and centering when reading a magnetic storage device arranged around the circumference of the bottle, a pot- or ring-shaped element is provided at the lower part of the bottle, this element being made of a magnetizable material.

[0009] To prevent protrusions on the bottle's surface where dirt could accumulate, the outer diameter of the pot- or ring-shaped element corresponds to the outer diameter of the upper part of the bottle. As further explained, smooth and unstructured shapes are particularly advantageous when handling perishable dairy products, given the stringent hygiene requirements. For hygiene reasons, a tight seal between the pot- or ring-shaped element and the bottle is crucial to prevent milk from penetrating between the bottle and the element.

[0010] The familiar milk sample bottle, however, has several disadvantages. A barcode is placed on the middle of the bottle for identification purposes. With repeated use, the barcode becomes increasingly difficult to read due to external factors such as washing, weather conditions, etc. Furthermore, the barcode affixed to the round sample bottle requires a device to rotate the bottle around its axis.

[0011] Milk sample bottles are typically made of plastic. With a hollow, pot-shaped holder at the bottom of the bottle, even with a precisely manufactured seal between the holder and the bottle, it's possible for liquid, along with germs, to seep into the cavity and remain there for an extended period, leading to mold growth. This is especially true if the sample bottles are intended for multiple uses. Such leaks can occur, for example, when the samples are heated in a water bath.

[0012] From DE 10 2004 043 883 B4 a milk sample bottle is known which has a TAG in the lower part of the bottle body.

[0013] However, the device has the disadvantage that the TAG lacks a cap-shaped retaining element, resulting in numerous recesses in the lower part of the bottle. These recesses pose a hygiene problem, as liquid residue can accumulate in the nooks and crannies. These intricate areas are very difficult to clean. From a hygiene perspective, this milk sample bottle therefore represents a step backward compared to the known milk sample bottle according to EP 0 411 274 B1. Problem and solution of the invention

[0014] Object of the invention: An identifiable reusable sample bottle should be developed that is suitable for hygienic handling.

[0015] This problem is solved according to the invention by the features of claim 1.

[0016] The cap has a closed shape to prevent liquid from entering hard-to-clean cavities in the area between the cap and the bottle body. The base of the bottle body extends into the cap so that, despite the closed, hollow cap, the center of gravity of the filled sample bottle remains sufficiently low. Advantages of the invention

[0017] Among other things, the following advantages are achieved: The reusable sample bottle, in particular a milk sample bottle, has a holding device (3) which protects the electronic component (4) as best as possible by means of an airtight seal.

[0018] Reusable sample bottles are commonly used in the dairy industry, where samples must be clearly identifiable and traceable to comply with required testing standards. Since thousands of these sample bottles are used daily, the aspect of multiple uses, combined with environmental friendliness and cost-effectiveness in production, is particularly noteworthy. Firstly, the reusability of the sample bottles ensures that acquisition costs remain consistently low. Secondly, the reusable bottles are also environmentally friendly. This represents a clear advantage in light of intense competition.

[0019] The properties of the sample bottle are described in detail in the data sheet “PIK NRW Data Sheet” of the State Control Association of North Rhine-Westphalia eV.

[0020] The sample bottle consists of a reusable bottle body (1), a bottle cap (2), a circular, centrally located recess (6) on the bottle body (1), a colored mounting device for the electronic component (3), and an electronic read / write memory component (TAG) (4). The use of the bottle cap (2) is optional, depending on the intended use.

[0021] The challenge in ensuring the reusability of the sample bottles lies in preventing any liquid from penetrating the TAG during the cleaning process. Therefore, a key focus for this sample container is the tightness of the bottom lid to guarantee multiple uses.

[0022] In developing the sample bottle according to the invention, the inventors overcame the following technical difficulties in a non-obvious manner, as will be shown below based on the development history of the sample bottle with integrated RFID.

[0023] To err is human – therefore, it is not surprising that, despite special arrangements in designated boxes, samplers can make mistakes when taking samples on various dairy farms. This can lead to the sample not being assigned to the correct animal, resulting in an inaccurate test result.

[0024] Furthermore, the fixed sequence for taking samples often dictates the order in which they are examined in the sample holder. Sampling machines frequently rely on the correct insertion sequence, thus perpetuating the error. This can lead to a dairy product being classified as good when it might actually be contaminated, or vice versa. Particularly in the food industry, such errors can have disastrous consequences, rendering a large number of samples unusable.

[0025] This is precisely the problem addressed by the development history and several other development ideas on this topic. Over the years, many methods have been tested and implemented; however, these methods were often not 100% reliable in detection, or the production costs were so high that they were deemed economically unviable for laboratories.

[0026] One of the methods involves using a box and a stand for sample collection. Unfortunately, it quickly became apparent that the method was dependent on the sampler's position and factors such as whether they were left- or right-handed, as well as hectic workflows and distractions. The error rate for this method remained high, as human error was still a possibility.

[0027] In a further development attempt, the use of a barcode affixed to the container was explored. Not only was the effort involved in applying the barcode a disadvantage, but the likelihood of its readability being negatively affected by external factors (washing, weather, etc.) was also ever-present. Added to this were the adhesive's lifespan and its purchase price. Another drawback of the barcode method became apparent in the typically round shape of the sample containers – to ensure a barcode scanner could read the code accurately, a device was often required to rotate the bottle around its axis.

[0028] Based on these initial methods for developing an economical and reliable solution, the first idea aimed for a more robust method of identification – the use of an RFID chip. In the first development step, the inventors positioned this chip inside the sample container, and the reading and writing process generally worked flawlessly. However, disadvantages of this solution included the fact that the milk was in direct contact with the electronic component, and potential contamination could not be ruled out. Furthermore, the higher density of the milk often caused the chip to float to the top, making it difficult to read during the scanning process. Another drawback the inventors found was that, during the cleaning process, the RFID chip, positioned at the bottom of the bottle, blocked access to contaminants there, meaning the cleaning effectiveness could not be considered 100%.

[0029] Based on the initial results, the inventors decided to design a separate "base" for the bottle, equipped with a thread. This prevented the chip from contaminating the sample and allowed the cleaning process to proceed without interruption. While this second idea was already an improvement over the status quo, the inventors now had to contend with condensation and water in the base, which would eventually lead to mold growth.

[0030] Based on their findings, the inventors further developed the idea and designed a base with circular holes. This allowed them to counteract the accumulation of condensation and prevent mold growth. However, the lack of a watertight base proved problematic when the inventors heated the samples in a water bath. When lifting the samples from the bath, water could drip from the holes and contaminate other samples.

[0031] The inventors therefore discarded this idea once again and went back to the approach of a closed underbody. They needed to find a solution to the problem of mold growth, and this solution was an "airtight seal." The inventors designed version 2.0 of the underbody so that the space within it precisely matched the circumference of the RFID chip, and they completely filled the remaining space with adhesive. If the RFID chip malfunctioned, it could still be replaced at any time via the threaded connection.

[0032] When the inventors subjected this idea to an economic analysis, they discovered that producing such a thread would be very expensive. Therefore, while they ultimately decided to pursue this idea, they made several optimizations. They opted to replace the expensive thread with the plug-in mechanism described in the patent, which, however, cannot be opened manually. According to their calculations, it is significantly cheaper to forgo the high production costs of the thread and the replaceable chip, and instead, in the event of a defect, replace the entire bottle, including the RFID chip. The described plug-in mechanism is very cost-effective to produce. Throughout this progressive development, the inventors continuously optimized the original idea.The locking mechanism described in the patent, together with the other described components, thus demonstrates the final solution to the problem.

[0033] Advantageous embodiments of the invention are set out in the dependent claims.

[0034] It is therefore suggested that - that the mounting device (3) is connected to the outer lower area of ​​the bottle body (1) by means of a tongue and groove arrangement (7, 8, 9), - that the mounting device (3) can be manually connected to the bottle body (1), but afterwards cannot be manually detached, - that the TAG (4) is circular in shape and is positively locked in the also circularly shaped mounting device (3), - that the mounting device (3) has a groove formed from two parallel annular protrusions (8, 9), - that the bottom area of ​​the bottle body (1) opens upwards and has the spring which is formed as a bulge (7), - that the holding device (3) and the bottle body (1) are made of plastic, in particular polypropylene or polyethylene. Example of implementation

[0035] An embodiment of the invention is described in more detail below with reference to the drawings. In all drawings, identical reference numerals have the same meaning and are therefore explained only once, if necessary.

[0036] They show Fig. 1. the bottle body in its assembled state, Fig. 2 Bottle body (1), TAG (4), bottle cap (2) and mounting device (3) in individual view, Fig. 3 Close-up of the bottle body (1) showing the interlocking mechanism, Fig. 4 Close-up of the mounting device (3) showing the gearing, Fig. 5 Close-up of the centering point (12). Structure and operation of the sample bottle according to the invention

[0037] The sample bottle is made of plastic (e.g., polypropylene or polyethylene) and is therefore inexpensive to produce and, due to its light weight, cost-effective to transport. These characteristics of a durable material are further enhanced by its multiple uses throughout the process chain, thus meeting society's contemporary demand for a sustainable solution. The use of single-use plastic bottles and their disposal are heavily criticized from an environmental perspective, making this reusable solution a significant advantage in terms of public image as well.

[0038] The bottle neck (5) is precisely fitted to the bottle cap (2). The bottle neck (5) slopes slightly outwards towards the end. The smooth surface of the inside of the bottle neck (5) facilitates easy attachment of the cap (2) without requiring much force and ensures a tight seal. The design is specifically intended for use in stands or conveying systems used in the dairy industry.

[0039] Within the dairy industry, samples must be clearly identifiable and traceable at all times to comply with required testing standards. Some systems already allow for sample identification using a barcode, which is "read" by scanners during the process. However, this current state of the art requires a direct line of sight between the label and the scanner, which is not always feasible in the automation of dairy production lines. Furthermore, reading the barcode requires the sample bottle to be rotated evenly. These sample bottles are often used or "read" only once and then discarded.

[0040] The desire to make samples identifiable using current technology such as the "TAG" is not new. The aim is to prevent human error in the form of sample mix-ups through the use of a TAG (4) and, at the same time, to facilitate data-driven and automated processing of the analysis results for subsequent processes. The conversion from QR code to TAG (4) will be carried out gradually, so that during the transition, the already proven technology for bottle identification will continue to be used. This process involves the circular application of an optical marking to the recess of the bottle body (6). This recess, already present on the standard sample bottle, has so far served as the only identification option via QR code or barcode, which, however, has the disadvantage that a direct line of sight between the scanner and the code must always exist.In the future, the bottle will continue to contain the proven recess, which, in addition to the main identification method via TAG (4), could optionally contain coded supplementary information in the form of a barcode, QR code, color codes, or plain text marking for the sample. However, the major challenge with technical components and their use in environments with liquids always lies in the tightness or protection of the component, which, according to the invention, is the basis for the design of the illustrated holding device.

[0041] The mounting device (3) enables robust attachment of the tag (4) to the bottle body (1) and can only be returned to its original position by forced demolding using high force. This feature serves to protect the tag (4) as mentioned above, ensuring it remains shielded from any external influences and does not come into contact with liquids, even during the cleaning process of the reusable sample bottle. However, the mounting device (3) can be attached manually, allowing the assembly to be set up once by hand and used flexibly on-site. Only removal cannot be achieved by force alone, thus preventing tampering with the chip and potential damage. The mounting device (3) is made of plastic to keep the weight of the sample bottle low, unlike a mounting device made of metal.This is particularly important with regard to the transport of many bottles.

[0042] The interaction between the bottle body (1) and the mounting device (3) is described in Fig. 3 and Fig. Figure 4 illustrates this. The diameter of the tag (4) corresponds exactly to the inner diameter of the holder (3), thus limiting the movement of the tag (4). Additionally, the tag (4) has a recess that aligns precisely with the protrusion of the centering point (12) on the holder (3). This fixed position of the tag (4) at the base of the holder (3) ensures a largely error-free operation in the automated identification process at the feeding station of the testing unit, as an identical read / write range is maintained at all times with the same bottle position, and the tag (4) cannot slip.

[0043] In addition to the precise vertical fit of the tag (4), the gaps between the mounting device (3) and the bottle body (1) are also precisely aligned. The grooves (10) were designed as in Fig. Figure 4 shows an optimized design so that the protrusion on the bottle body (1) fits into the protrusions (8) and (9) on the holding device. It was specifically ensured that both the grooves and the protrusions extend around the entire bottle body. The dimensions of the grooves and protrusions were selected in this form after extensive testing. This is the only way to guarantee that this sealing mechanism ensures a tight seal at the base, which is of paramount importance for hygiene, data quality, and data availability. At the same time, the sealing mechanism described above protects the tag from tampering. It ensures that the base, with the tag inside, cannot be manually removed from the body of the reusable sample bottle. Furthermore, it is impossible to reassemble the bottle base and body after mechanical damage.

[0044] In addition, a high overall stability of the sample bottle base is achieved and the center of gravity of the sample bottle is lowered, thus improving the stability of the sample bottle.

[0045] The use of this plug-in system not only offers the advantage of excluding liquid during the cleaning process of the reusable sample bottle, but the production costs for this closure mechanism are also significantly lower than those for manufacturing a threaded connection. The same applies to the fitting of the bottle with a tag (4). The assembly consisting of the bottle body (1) and the mounting device (3) serves as the basis for an automated identification process, which, due to decreasing costs for storage electronics, can be characterized as cost-effective, durable, and reliable.

[0046] This virtually airtight seal is an effective preventative measure against unwanted external influences, such as contaminated liquids or dirt, which could distort the analysis result and damage the TAG (4). As a further protective mechanism, specifically against condensation, the mounting device (3) is sealed airtight to the bottle body using adhesive or silicone. Filling the entire mounting device (3) with the adhesive or silicone thus counteracts the condensation of any liquid that may have entered and prevents contamination. It should also be emphasized that filling the mounting device (3) has the added advantage of preventing the sample bottle from floating, for example, in a water bath. This prevents the sample from tipping over and becoming contaminated in the water bath.

[0047] The mounting device (3) is currently green. In the future, however, different colors for this mounting device (3) will be offered as an additional coding option. This would allow, for example, different colors for each industry or major customer – and even different colors depending on the frequency range of the RFID chip. The different color options will only marginally affect production costs, but will provide significant benefits through the additional visual coding for samplers and customers.

[0048] Since the sample bottles are not disposable, the TAG (4) adapts optimally to this situation and can be reused multiple times. The invention is based on the idea of ​​using the TAG (4) as a data carrier for modifiable sample data and for identification purposes (rewritable) and achieving simple yet protected positioning of the storage component on the sample bottle by means of the sealed mounting device (3). Its protected position within the mounting device (3) safeguards it from external influences such as UV radiation or detergents during the cleaning process after previous use. In this way, the sample bottle represents a "green" reusable solution, is not a disposable product, and benefits the environment. The exclusion of external influences within the mounting device and the filling of the cavity drastically extend the service life of the electronic component.Therefore, the mounting device (3) can be used universally for all TAGs (4) and supports all frequency ranges. Future developments can thus utilize not only TAGs in the high-frequency range, but also TAGs (4) in the ultra-high-frequency range. Other frequency ranges are also possible.

[0049] From a technical perspective, the TAG (4) consists of a chip and a coil. Data and energy transmission is contactless (based on the principle of induction). Adjusting the coil windings changes the antenna frequency, allowing the read / write range to be individually adapted as needed without altering the external shape (diameter). This technology therefore offers significant flexibility in the process model and can be customized to specific requirements. Further functional expansion of the TAG is planned within the scope of technical possibilities and requirements.

[0050] The identification of individual sample bottles is achieved by reading the data stored on the tag (4). The tag therefore functions as both a display device and a storage device. For example, chips operating in the high-frequency range with a standard frequency of 13.56 kHz would be suitable for the present invention. These tags are also suitable for use at higher temperatures, for example, for positioning within a water bath or during the cleaning process. Of course, any equivalent read / write memory components can be used based on the invention.

[0051] The identification method via the tag (4) integrated in the mounting device (3) can be classified as being as highly reliable and secure.

[0052] Encryption of stored data, such as client information, sample data, timestamps, location, etc., is easily possible upon request. All processes are recorded, ensuring a complete data history for the sample. The stored data can also be graphically processed for clients / customers as part of analysis requests and forwarded via control systems or databases. Any defects in the substance can be reported to the client based on the data. Furthermore, the identification process of the reusable sample bottle can be displayed in real time, allowing the client to track their order and its results, including all data such as time, location, etc., in real time. This can also be actively integrated into an existing quality management system. Important decisions, such as taking a milk sample from an animal, can be made quickly and unambiguously, thus accelerating the process.Additional orders can be forwarded to the laboratory via the TAG.

[0053] The reusability of the reusable sample bottle can be considered a decisive competitive advantage from an economic perspective. However, this classification does not refer solely to the bottle's production costs. The design of the sample bottle also promotes economic efficiency, as the invention is based on the premise of not altering the original parameters of the existing, commercially available sample bottle by combining the bottle body (1) and the holding device (3). By maintaining the external dimensions, neither transport equipment nor stands, boxes, feeding stations, etc., need to be adapted accordingly. Therefore, there is no need to dispose of "old" equipment when introducing the new bottles.The recess previously used in the industry remains a feature of the bottle, allowing the existing method of scanning for optical marking to continue during the transition to the TAG system. Alternatively, as mentioned, the recess can be used to store additional information. The reusable sample bottle shown thus complies with the "universal stand system," simplifying the approval process and significantly facilitating its use in all laboratories, particularly for milk analysis. Maintaining the bottle dimensions, the recess for the barcode, and the center point (12) for the omnidirectional scanner allow the bottle to be used without major machine or process adjustments. This means that existing customers can use the new reusable sample bottle without any problems. This also applies to suppliers and ancillary processes, such as...No adjustments are necessary for the cleaning process of the sample bottles because the dimensions remain the same.

[0054] Sample identifiability is guaranteed throughout the entire value chain in the dairy industry, not least thanks to the universal stand system. At all relevant stations, e.g. • Tank truck at dairy, • Sampling on the dairy farm, • Laboratory, • On transport conveyor belts, etc., sample identification can be guaranteed and direct compliance with quality standards is promoted. The holding device (3) not only enables multiple uses and a tight seal, but also prevents unauthorized and manipulative interference with the data flow through its irreversible fastening. Regarding Fig. 1: Bottle body in assembled state

[0055] In this state, the reusable sample bottle goes through the process from collection to laboratory / testing. The dimensions of the sample bottle shown are... Fig. The 1.00-liter containers correspond to the standard sampling dimensions used in the dairy industry and can therefore be processed without modification, which again supports the ecological aspect. No resource-wasting adjustments or disposal of standard processing equipment are necessary. Fig. 2: Bottle body (1), TAG (4), bottle cap (2) and mounting device (3) in detail

[0056] The interaction with the special locking mechanism of the mounting device (3) with the bottle body is in Fig. Figure 2 shows the TAG (4). It is placed in the holder (3) at the centering point, ensuring a secure position. The sealing mechanism, along with the adhesive filling of the interior, ensures optimal sealing and enhances the longevity of the TAG (4). The optional bottle cap, with its rounded shape, provides an optimal closure mechanism that protects the sample. Regarding Fig. 3: Close-up of bottle body (1) - illustration of the toothing

[0057] The sealing mechanism between the sample body and the holder (3) is essential for the service life of the TAG (4). Only by creating an airtight seal and filling the cavity of the holder (3) with adhesive or silicone can the integrity of the TAG (4) be guaranteed. Fig. Figure 3 shows the groove (7) on the bottle body, which plays an important role in the closing mechanism. The tightness of the retaining device was confirmed in laboratory tests. Regarding Fig. 4: Close-up of the mounting device (3) - representation of the gear teeth

[0058] The centering point on the mounting device (3), which also acts as a connecting link for the TAG, is in Fig. 4. Any incorrect positioning of the TAG (4) is prevented by this centering point and the aforementioned filling of the cavity. The toothed grooves on the mounting device (3) fit precisely into the grooves. Fig. 3, so that an airtight seal can be achieved. Regarding Fig. 5: Close-up of center point (12)

[0059] The centering point is crucial for the use of a scanning process. For example, if a barcode label is attached to the recess (6) on the bottle body, the bottle must be rotated during the scan, for which the centering point serves as a technical aid. Inside the holder (3), the bulge is also of great importance, as it stabilizes the position of the tag (4). This prevents the tag (4) from moving and, for example, from sustaining lasting damage if the bottle is dropped.

[0060] Fig.Figure 2 shows the assembly of a sample bottle. The bottle body (1) is made of plastic materials such as polypropylene or polyethylene and corresponds in shape, dimensions, and material to conventional sample bottles widely used in milk sampling. First, the tag (4) is inserted into the holder (3), and the cavity is filled with adhesive or silicone to prevent moisture ingress. Then, the bottle body (1) is pressed into the holder (3) with a force of at least 50 kg, corresponding to a click mechanism. The special locking mechanism connects the bottle body (1) and the holder (3). Any moisture ingress is effectively prevented by the locking mechanism underlying the invention.The area between the curve (7) and the bottle base (7 mm) was chosen to ensure sufficient adhesive distribution across the surface and thus guarantee a secure seal. This connection cannot initially be broken by brute force, thus preventing unwanted interference and manipulation.

[0061] Based on the very favorable production costs of the illustrated sample bottle model including TAG and special holding device (3), it would be more economical to dispose of the bottle in the event of a defect occurring in the TAG itself.
