Description

Technical Field

[0001] This utility model relates to the field of test paper technology, and in particular to a plastic container for oil test paper. Background Technology

[0002] Oil test strip plastic containers are mostly lightweight and durable small-sized shells, often with simple markings on the surface for easy identification of their purpose. The container design fits comfortably in the hand, preventing slippage when handling the test strips. The internal space is adapted to the size of the oil test strips, allowing for neat storage and reducing the possibility of moisture or dust accumulation. Some containers have a sealed top lid, which further ensures the dryness and cleanliness of the test strips when closed. They can be stored with the oil test strips in toolboxes, drawers, etc., without taking up much extra space. Simply open the top lid to take out the test strips when needed, and close the top lid promptly after use. This facilitates more convenient and organized oil testing operations, making them a practical auxiliary tool for use with oil test strips.

[0003] In the storage of testing consumables such as oil test strips that are susceptible to humidity, traditional containers often use fixed desiccant packs. The release rate of the desiccant is fixed and cannot be flexibly adjusted according to changes in humidity inside the container. When the container is frequently opened, causing external moisture to enter, the desiccant is prone to rapid saturation and failure, making it difficult to maintain a dry internal environment. The lack of a design to actively replenish the drying efficiency makes it impossible to adjust in time when humidity rises. As a result, the test strips are prone to problems such as increased detection errors and shortened shelf life in the later stages of storage due to moisture absorption. Therefore, a plastic container for oil test strips is needed. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a plastic container for oil test paper that can solve the problems of fixed desiccant packs having a fixed release rate of drying components and cumbersome replacement, which makes it difficult to continuously and stably control the humidity inside the container and cause the desiccant to fail quickly, thus affecting the detection accuracy and shelf life of the oil test paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic container for oil testing paper, comprising a container lid and a press-type desiccant compartment. The press-type desiccant compartment includes a desiccant shell, a connecting rod, a return spring, a pressing plate, and a piston. The desiccant shell is fixedly connected to the inside of the container lid. The connecting rod is slidably connected to the desiccant shell and extends out of the container lid. The outer surface of the connecting rod is slidably connected to the container lid. An opening is provided on the container lid for the connecting rod to pass through. The return spring is fixedly connected to the top of the container lid. The pressing plate is fixedly connected to the top of the connecting rod. The top of the return spring is fixedly connected to the pressing plate. The piston is slidably connected to the inside of the desiccant shell. The outer surface of the piston contacts the inner wall of the desiccant shell. The top of the piston is fixedly connected to the connecting rod.

[0006] Preferably, a desiccant is fixedly connected inside the desiccant shell, a detachable plate is movably connected to the bottom of the desiccant shell, and a breathable membrane is fixedly connected to the surface of the detachable plate.

[0007] Preferably, the top of the detachable plate is fixedly connected to a locking block, and the detachable plate is engaged with the desiccant shell through the locking block. The bottom of the desiccant shell is provided with a slot that matches the locking block.

[0008] Preferably, the bottom of the container lid is threadedly connected to the container body, and the bottom of the container body is rotatably connected to a base.

[0009] Preferably, the outer surface of the container lid is provided with external threads, and the inner wall of the container body is provided with internal threads, the internal threads and external threads being compatible.

[0010] Preferably, a second transparent window is fixedly connected to the surface of the container body, and a first transparent window is fixedly connected to the surface of the base.

[0011] Preferably, a plastic clip is fixedly connected to the bottom of the container body, and multiple limiting grooves are equidistantly provided on the outer surface of the base.

[0012] Preferably, there are two plastic clips symmetrically arranged on both sides of the container body, and each plastic clip is engaged in the corresponding limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This plastic container for oil test strips utilizes an operable mechanical structure to achieve active control and flexible adjustment of the release of drying components. Compared to traditional fixed desiccant packs, it enhances drying efficiency through a pressing action based on changes in humidity within the container and actual usage needs, improving the targeting and timeliness of the drying process. Its structural design keeps the desiccant within a relatively sealed shell, reducing direct contact between the drying components and the external environment, slowing down the desiccant saturation rate, extending its effective lifespan, and reducing the frequency of desiccant replacement and usage costs. Simultaneously, the container employs a snap-fit, detachable plate structure, facilitating rapid desiccant replacement without completely disassembling the container, reducing the risk of external moisture and contaminants entering and ensuring the stability of the internal storage environment. Furthermore, its integrated design allows for a tight fit with the container lid without occupying additional internal storage space, ensuring the test strip storage capacity remains unaffected. It also simplifies the overall container structure, improving assembly and ease of use, meeting the design requirements of efficient, stable, and easy-to-maintain testing consumable storage containers.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4This utility model provides a technical solution: a plastic container for oil testing paper, wherein:

[0026] The outer surface of the container lid 1 is provided with an external thread 9, and the inner wall of the container body 2 is provided with an internal thread 8. The external thread 9 and the internal thread 8 are matched and the two are tightly connected by thread engagement, which not only ensures the sealing of the container, but also facilitates opening and closing operations. The material is mostly food-grade plastic, which is safe and durable.

[0027] A plastic clip 4 is fixedly connected to the bottom of the container body 2. Multiple limiting grooves 5 are equidistantly opened on the outer surface of the base 3. There are two plastic clips 4 arranged symmetrically. Each plastic clip 4 is locked in the corresponding limiting groove 5, so that the container body 2 and the base 3 are relatively fixed. At the same time, the position can be adjusted by rotation, which is simple and flexible to operate.

[0028] A second transparent window 7 is fixedly connected to the surface of the container body 2, and a first transparent window 6 is fixedly connected to the surface of the base 3. Both are made of transparent plastic. When the container body 2 is rotated so that the two windows overlap, the internal situation can be observed. When separated, they can block light, which is convenient for viewing and avoids strong light from affecting the performance of the test strip.

[0029] The desiccant shell 10 is fixedly connected to the inside of the container lid 1, and the desiccant 15 is fixedly connected inside it. A detachable plate 16 is movably connected to the bottom, and a locking block 17 is fixedly connected to the top of the detachable plate 16. A slot adapted to the locking block 17 is opened at the bottom of the desiccant shell 10. The detachable plate 16 is fixed by the locking block 17 and the slot, which facilitates the subsequent replacement of the desiccant 15.

[0030] A breathable membrane 18 is fixedly connected to the surface of the detachable plate 16. The breathable membrane 18 is made of a breathable but waterproof polymer material, which can both allow the desiccant 15 to absorb moisture and prevent the desiccant particles from leaking, thus ensuring the cleanliness of the storage environment inside the container.

[0031] The connecting rod 11 is slidably connected to the desiccant shell 10 and extends out of the container lid 1. The container lid 1 has an opening for the connecting rod 11 to pass through. The outer surface of the connecting rod 11 is slidably connected to the opening, providing stable guidance for the up and down movement of the connecting rod 11 and ensuring smooth operation of the structure.

[0032] The pressing plate 13 is fixedly connected to the top of the connecting rod 11. The return spring 12 is fixedly connected between the top of the container lid 1 and the pressing plate 13. The piston 14 is fixedly connected to the bottom of the connecting rod 11 and slidably connected inside the desiccant shell 10. The outer surface of the piston 14 is in close contact with the inner wall of the desiccant shell 10. When the pressing plate 13 is pressed, the connecting rod 11 drives the piston 14 to move down and the return spring 12 is compressed. After being released, the return spring 12 drives all components to return to their original positions, which can actively enhance the drying efficiency and extend the shelf life of the test paper.

[0033] Working principle: When the oil test strip plastic container is needed, the container cap 1 is sealed by screwing the external thread 9 into the internal thread 8 of the container body 2. The container body 2 is fixed in place by the plastic clip 4 in the limiting groove 5 of the base 3. Rotating the container body 2 so that the first transparent window 6 and the second transparent window 7 overlap to observe the internal situation, and rotating the container body 2 so that the first transparent window 6 and the second transparent window 7 separate to ensure the light-blocking effect and control the light transmittance. This makes it convenient to check the remaining amount of test strip and avoids strong light from affecting the performance of the test strip. Pressing the pressing plate 13 moves the connecting rod 11 down, and the piston 14 slides down inside the desiccant shell 10. The return spring 12 is compressed. After releasing the pressing plate 13, the return spring 12 returns to its original position, driving all parts back to their original positions. The desiccant 15 inside the desiccant shell 10 absorbs moisture in the container through the breathable membrane 18. Pressing can replenish the drying components and extend the shelf life of the test strip. The detachable plate 16 is engaged with the desiccant shell 10 by the clip 17 to facilitate the replacement of the desiccant 15.

[0034] Example 1: (Reference) Figure 1-4 )

[0035] The light-transmitting structure formed by the second transparent window 7 of the container body 2 and the first transparent window 6 of the base 3 serves two purposes. First, rotating the container body 2 allows the two windows to overlap, enabling direct observation of the remaining amount of edible oil testing paper inside for timely replenishment. Second, rotating the container body 2 when no observation is needed separates the two windows, achieving complete light blocking and preventing direct sunlight in the kitchen from aging the test reagents in the test strip, thus ensuring test accuracy. Furthermore, during transportation, the separated light-blocking state of the two windows also prevents interference from external light, protecting the stability of the test strip performance. The detachable plate 16, in addition to being secured to the desiccant shell 10 via the latch 17 for easy periodic replacement of the saturated desiccant 15, also features a breathable membrane 18 fixed to its surface, which serves a dual purpose: allowing the drying components of the desiccant 15 to penetrate into the container while preventing small debris from the edible oil testing paper during use from entering the desiccant shell 10, thus avoiding blockage and affecting the drying effect, and preventing desiccant 15 particles from leaking and contaminating the test strip. The external thread 9 on the outer surface of the container lid 1 engages with the internal thread 8 on the inner wall of the container body 2. This not only seals the container by screwing it in, preventing kitchen fumes and moisture from entering, but also allows for adjustment of the tightness of the seal by controlling the degree of screwing. When frequently using the test paper in a short period, it can be slightly loosened to reduce opening and closing resistance and improve ease of operation. When stored for a long period, it can be fully tightened to ensure a good seal and extend the shelf life of the edible oil test paper.

[0036] Example 2: (Reference) Figure 1-4 )

[0037] Food processing companies purchase edible oil testing papers in bulk for oil quality monitoring on their production lines. These papers require long-term storage and strict stability requirements. The press-type desiccant compartment allows for periodic (e.g., every two weeks) pressing of the press plate 13, which, through the sliding of the piston 14, ensures even distribution of the desiccant 15 within the desiccant shell 10. This prevents localized saturation of the desiccant 15, maintains a consistently dry environment within the container, and prevents the edible oil testing papers from becoming damp and deteriorating due to long-term storage. After a period of use, the desiccant 15 can be quickly replaced by disassembling the removable plate 16 (using the locking block 17 and the slot in the desiccant shell 10), without completely disassembling the container, reducing the risk of external contaminants entering during replacement. Furthermore, the container lid 1 and container body 2 are connected by external threads 9 and internal threads 8, along with a transparent window for light blocking, effectively isolating them from external humidity fluctuations and strong light. This ensures that the edible oil testing papers maintain stable accuracy over a storage period of up to 6 months, meeting the stringent standards for bulk storage by enterprises.

[0038] Example 3: (Reference) Figure 1-4 )

[0039] Restaurants routinely use cooking oil testing paper to check the quality of frying oil. However, the containers are prone to being contaminated by kitchen steam, fumes, and other moisture due to frequent use of the test paper. In this case, a press-type desiccant compartment allows the operator to press the press plate 13 as needed, which drives the connecting rod 11 to push the piston 14 within the desiccant shell 10. This accelerates the contact between the desiccant 15 and the air inside the container, quickly absorbing the intruded moisture and residual fumes, preventing uneven color development during testing due to moisture or oil absorption on the cooking oil testing paper. Simultaneously, the container body 2 and base 3 are fixed by plastic clips 4 and limiting grooves 5. Rotation adjusts the overlap of the first transparent window 6 and the second transparent window 7, allowing for quick checking of the remaining test paper and providing light shielding in bright kitchen environments by separating the transparent windows. This prevents strong light from affecting the accuracy of the cooking oil testing paper, meeting the needs of restaurants for immediate and high-frequency testing.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
