Description

Technical Field

[0001] This utility model relates to a sample sealing and preservation container, specifically a sample sealing and preservation container for food testing. Background Technology

[0002] Generally, multiple samples are randomly taken during the production process of food products, and then sent to the food testing center in the factory for testing to ensure that the food safety of this batch of products meets the relevant technical indicators.

[0003] The relevant testing methods can be found in Chinese authorized patent, publication number CN111242170B, publication date 2023-07-25, which discloses a method and device for predicting food inspection and testing items.

[0004] In existing technologies, including the aforementioned patents, the collection of food samples involves a high degree of randomness. This randomness refers to the randomness of the food sampled and the randomness of the sampling time (but the interval cannot be too long). Once a certain number of samples are collected, they need to be sent for testing in a centralized manner. Therefore, a sample storage box is required in this process. However, the existing storage box designs are relatively simple, only fulfilling the function of storing samples, without corresponding designs for other additional functions. Utility Model Content

[0005] The purpose of this invention is to provide a sealed container for food testing samples to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food testing sample sealed storage container, including a sample tube, including a cap hinged to one side of the box body port section, the box body is provided with a decorative part, and the decorative part has a plurality of perforations arranged in a matrix for inserting the sample tube;

[0007] It also includes a test tube holder that is slidably fitted into the housing and moved relative to the decorative part by a drive.

[0008] Preferably, the inner walls of the opposite sides of the cover are hinged with connecting rods whose ends are inserted through notches reserved in the side walls of the decorative part;

[0009] The test tube holder includes a grid support with symmetrically distributed crossbeams. The end of the connecting rod is slidably disposed in a first groove on the side of the crossbeam.

[0010] Preferably, the connecting rod extending into the housing has a second waist groove and also includes a sliding limiting member that passes through the second waist groove and is slidably fitted into the first waist groove.

[0011] Preferably, a high-density sponge base is fixedly installed on the side of the grid support opposite to the decorative part, and the high-density sponge base has an arc groove that matches the round bottom of the sample tube.

[0012] Preferably, when the high-density sponge base is placed at the bottom of the box, the port cross-section of the sample tube is lower than the upper surface of the decorative part.

[0013] Preferably, the side walls of the enclosure on both sides are provided with heat dissipation windows, and the heat dissipation windows are composed of multiple long rectangular strip holes, which are arranged vertically and the coverage height is equal to the height of the grid support.

[0014] Preferably, the maximum opening angle of the box and the cover is greater than 90° and less than 120°.

[0015] Preferably, a high-density sponge pad is embedded inside the sealing port.

[0016] Preferably, the high-density sponge pad is fixedly provided with water droplet protrusions arranged in a matrix on the side facing the box body, and the water droplet protrusions are coaxial with the perforations.

[0017] In the above technical solution, the food testing sample sealing and preservation container provided by this utility model has the following beneficial effects:

[0018] 1. The test tube holder can move along the direction of the box relative to the decorative part, so as to cooperate with the opening or closing of the cap and drive the sample test tube to move with the test tube holder. That is, when the cap is open, the test tube holder moves upward, so that the port of the sample test tube is higher than the upper surface of the decorative part, making it easy to pick up; when the cap is closed, the test tube holder moves downward, so that the port of the sample test tube is lower than the upper surface of the decorative part.

[0019] 2. The vertical movement of the test tube holder is achieved through a linkage mechanism linked to the cap: when the cap flips, the linkage pulls the test tube holder, causing it to rise and fall with the opening and closing of the cap; when the cap opens, the test tube holder moves upward, and when the cap closes, the test tube holder moves downward. This linkage mechanism also limits the maximum flipping angle of the cap. Simultaneously, the damping force provided by the sliding of the test tube holder against the inner wall of the chamber prevents the cap from slipping and falling rapidly during operation, thus avoiding a sudden backward tilt that could cause the chamber to overturn or instantly impact the chamber's opening, potentially injuring the operator's hand while handling the test tubes.

[0020] 3. The test tube holder uses a grid support and a high-density sponge support to ensure that most of the sample test tube is placed in the grid support, which facilitates internal ventilation and heat dissipation and prevents the sample test tube from being distorted due to temperature accumulation in a sealed environment.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-7This utility model provides a technical solution: a sealed sample preservation container for food testing, mainly used to store sample tubes 100. Before placing the sample tubes 100 into the preservation container, food samples need to be taken, crushed, and then placed into the sample tubes 100. Then, culture medium or other relevant liquids are added, and the ends of the sample tubes 100 are sealed. The above-mentioned preservation container includes the following embodiments:

[0033] Example 1

[0034] A cover 2 is mounted on one side of the port section of the housing 1 via a hinge, and a rectangular protrusion 7 is fixedly mounted in the center of the front of the cover 2 (polyethylene plastic part). Figure 1 When in the correct state, the rectangular buckle frame 71, which is rotatably mounted on the housing 1, needs to be flipped and fitted onto the front of the cover 2, so that the rectangular protrusion 7 is locked inside the rectangular buckle frame 71.

[0035] Furthermore, the port section of the cover 2 is integrally formed with an embedded lip 24, which is made of rubber and has an outer wall specification larger than that of the port of the box 1 (polyethylene plastic part). Therefore, when the cover 2 covers the box 1, it needs to be pressed so that the embedded lip 24 is embedded in the port of the box 1, thereby forming a seal. Secondly, when the cover 2 falls and touches the port of the box 1, the embedded lip 24 provides cushioning by touching the port of the box 1.

[0036] In the above embodiment, the housing 1 is provided with a decorative part 3, which has multiple perforations 31 arranged in a matrix for inserting sample tubes 100. In short, the decorative part 3 is a hard rubber sheet. Its sidewalls have a certain degree of flexibility and can deform, so the decorative part 3 is embedded in the port of the housing 1. Because of this embedding, the sidewalls of the decorative part 3 deform, thereby firmly embedding and fixing it to the housing 1.

[0037] Furthermore, it also includes a test tube holder 4 that is slidably mounted inside the housing 1 and moves relative to the decorative part 3 under drive. The test tube holder 4 is slidably mounted on the housing 1 and can move up or down under drive, thereby causing the sample test tubes 100 to move with the test tube holder 4. The design integrates the up-and-down movement of the test tube holder 4 with the flipping of the cap 2. That is, when the cap 2 is open, the test tube holder 4 moves upward, so that the port cross-section of the sample test tube 100 is higher than the upper surface of the decorative part 3 for easy retrieval; when the cap 2 is closed, the test tube holder 4 moves downward, so that the port cross-section of the sample test tube 100 is lower than the upper surface of the decorative part 3. The above can be achieved by adding a touch switch, which opens or closes the cap 2, and then the motor drives the lead screw to move the test tube holder 4. Alternatively, a rotation sensor can be added to detect the flipping of the cap 2 and convert it into an electrical signal, which in turn drives the lead screw to move the test tube holder 4, and the movement of the test tube holder 4 is synchronized with the flipping of the cap 2. Another driving method known to those skilled in the art is also acceptable.

[0038] Example 2

[0039] Based on the above embodiment 1, this embodiment aims to have connecting rods 21 (polyethylene plastic parts) hinged to the inner walls of opposite sides of the cover 2, with the ends protruding from the notches 32 reserved on the side walls of the decorative part 3, and the test tube holder 4 includes a grid support 41, which includes symmetrically distributed crossbeams 411, and the ends of the connecting rods 21 are slidably disposed in the first waist groove 412 opened on the side of the crossbeams 411.

[0040] Specifically, in the above embodiment, the connecting rod 21 is slidably mounted on the first waist groove 412. When the cover 2 is flipped to a predetermined angle, the end of the connecting rod 21 reaches the end of the first waist groove 412. As it continues to flip, the test tube holder 4 is pulled upward. The predetermined angle is a maximum opening and closing angle greater than 90° and less than 120°.

[0041] Furthermore, a plurality of rectangular receiving grooves 413 are formed on the aforementioned grid support 41, the purpose of which is to separate the inserted sample tubes 100.

[0042] Example 3

[0043] Based on the above embodiment 2, this embodiment aims to provide a second waist groove 211 on the connecting rod 21 that extends into the box 1, and also includes a sliding limiting member 5 (polyethylene plastic part), which passes through the second waist groove 211 and is slidably assembled in the first waist groove 412.

[0044] Specifically, when the cover 2 is flipped to a predetermined angle, the sliding limiter 5 reaches the ends of the second waist groove 211 and the first waist groove 412, as shown below. Figure 7 As shown, as the rotation continues, the test tube holder 4 is pulled upwards.

[0045] Furthermore, a high-density sponge base 42 is fixedly installed on the side of the aforementioned grid support 41 opposite to the decorative part 3. The high-density sponge base 42 has an arc groove 421 that fits the round bottom of the sample tube 100. The aforementioned grid support 41 is a polyethylene plastic part, which is inserted into the groove on the upper surface of the high-density sponge base 42 and then bonded and fixed with structural adhesive. The high-density sponge base 42 is interference-fitted with the inside of the box 1, so it has a certain damping force. The high-density sponge base 42 also has several ventilation holes to facilitate airflow during the up-and-down movement of the high-density sponge base 42.

[0046] In the above design, the vertical movement of the test tube holder 4 is linked to the cap 2 via the connecting rod 21. The cap 2 flips, and the connecting rod 21 pulls the test tube holder 4, thus opening the cap 2 and moving the test tube holder 4 upwards, or closing the cap 2 and moving the test tube holder 4 downwards. This also limits the maximum opening and closing angle of the cap 2, and the sliding damping force provided by the test tube holder 4 against the inner wall of the box 1 prevents the cap 2 from slipping out of hand during the sealing process, which could cause the cap 2 to tilt backwards and overturn the box 1, or cause the cap 2 to fall instantly and hit the port of the box 1, pinching the hand of the person handling the sample test tube 100.

[0047] Example 4

[0048] Based on Embodiment 3, this embodiment provides heat dissipation windows 6 on the side walls of opposite sides of the housing 1. The heat dissipation windows 6 are composed of multiple long rectangular strip holes, which are arranged vertically and cover a height equal to the height of the grid support 41.

[0049] Specifically, this embodiment aims to use the heat dissipation window 6 to maintain a consistent temperature between the inside of the housing 1 and the outside environment, preventing heat buildup inside. Furthermore, airflow during the up-and-down movement of the high-density sponge base 42 can also be discharged through the heat dissipation window 6.

[0050] Example 5

[0051] Based on Embodiment 4, this embodiment embeds a high-density sponge pad 22 inside the port of the cover 2. The high-density sponge pad 22 is fixedly provided with water droplet protrusions 23 arranged in a matrix on the side facing the box 1, and the water droplet protrusions 23 are coaxial with the perforation 31.

[0052] Specifically, when the cap 2 is in Figure 1 When in the indicated state, the water droplet protrusion 23 will abut against the end face of the plug at the port of the sample tube 1, thereby providing vertical cushioning in conjunction with the high-density sponge base 42.

[0053] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
