Description

Technical Field

[0001] This utility model belongs to the field of high elastic membrane boxes, and particularly relates to a high elastic membrane box with a high-cleanliness double-layer membrane structure. Background Technology

[0002] In current industrial production and scientific research applications, high-elasticity membrane boxes are widely used as a common component in fields with extremely high cleanliness requirements, such as biomedicine, semiconductor manufacturing, and precision optics. However, existing ordinary high-elasticity boxes on the market have revealed many problems in actual use, making it difficult to meet the needs of high-end scenarios.

[0003] From the perspective of membrane fixation technology, traditional fixation methods often struggle to stably secure double-layer membranes. During use, membrane displacement and loosening can easily occur, affecting not only the performance of the membrane cartridge but also potentially generating particulate matter and other contaminants due to membrane instability, thus reducing cleanliness. Moreover, traditional processes lack effective measures to ensure cleanliness when handling membranes, making it difficult to meet the requirements of high-cleanliness environments.

[0004] Regarding the snap-fit ​​structure, the friction point between the shell and the snap-fit ​​of ordinary high-elasticity boxes is often located inside the box. During use, this design allows debris, particles, and other contaminants generated by friction to easily remain inside the box, making them difficult to clean and severely impacting the cleanliness of the interior. This, in turn, contaminates the items stored inside, limiting its application in high-cleanliness fields.

[0005] In terms of material selection, the upper and lower shells of ordinary high-elasticity boxes are mostly made of PS or ABS materials. These materials have shortcomings in terms of purity, transparency, and cleanliness. PS or ABS materials may release organic matter and produce volatile substances, polluting the environment inside the box. The choice of buckle materials is also relatively common and cannot meet the requirements of high cleanliness and low volatility. In addition, ordinary films have low cleanliness, are prone to particle generation, and need to be improved in terms of stability and performance.

[0006] In summary, existing ordinary high-elasticity boxes have obvious defects in terms of film fixing process, box buckle structure and material selection, which makes it difficult for their cleanliness to meet the needs of high-end fields, and they urgently need to be optimized and improved. Utility Model Content

[0007] The purpose of this invention is to provide a high-cleanliness, double-layer membrane structure with high elasticity, aiming to solve the problems existing in the background art. To achieve this purpose, the technical solution adopted by this invention is:

[0008] A high-cleanliness, double-layer membrane structure with high elasticity includes...

[0009] The beneficial effects of this utility model are:

[0010] Significantly improved cleanliness: By optimizing the film fixation process, fixing the double-layer film and removing the outer layer after fusion, leaving only the inner layer, the potential introduction of contaminants during film processing is effectively reduced, ensuring high cleanliness inside the membrane chamber. Simultaneously, the use of low-particle clean films further reduces the risk of particle generation, enabling the membrane chamber to meet the extremely high cleanliness requirements of fields such as biomedicine and semiconductors.

[0011] The structural design is more rational: the friction points of the shell and buckles are all located on the outside of the box, preventing contaminants such as debris and particles generated by friction from entering the box. This structurally solves the contamination problem caused by improper friction point placement in traditional membrane boxes. This design allows the membrane box to maintain a more stable clean environment, improving the reliability and safety of the membrane box.

[0012] Superior Material Performance: The upper and lower shells are made of high-purity, high-transparency optical-grade polycarbonate. This material boasts extremely high purity and transparency, reducing the introduction of impurities while possessing excellent physical properties, ensuring the strength and stability of the membrane capsule. The clasps are made of metallocene high-purity polypropylene, exhibiting low volatility and minimizing the release of organic matter, further reducing pollution to the capsule's internal environment. Furthermore, all materials possess low volatility, significantly reducing the release of organic matter and providing a more reliable guarantee for a highly clean environment.

[0013] Wider range of applications: The optimized high-elasticity membrane box, due to its excellent cleanliness, reasonable structural design and superior material properties, can be widely used in high-end fields such as reagent storage in the biopharmaceutical field, protection of precision components in semiconductor manufacturing, and storage of components in precision optical instruments, thus expanding the application scenarios of the membrane box.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-2 As shown, this utility model embodiment provides a high-cleanliness double-layer membrane structure high-elasticity membrane box, including an upper shell 1, a lower shell 2, and a buckle 3. The upper shell 1 and the lower shell 2 are movably connected and locked together by the outer buckle 3. Both the upper shell 1 and the lower shell 2 are provided with a double-layer membrane 4 inside.

[0023] In this embodiment, the friction surfaces of the upper shell 1, lower shell 2, and buckle 3 are all located on the outside of the box.

[0024] In this embodiment, both the upper shell 1 and the lower shell 2 are made of high-purity, high-transmittance optical-grade polycarbonate.

[0025] In this embodiment, the buckle 3 is made of metallocene high-purity polypropylene.

[0026] Working principle:

[0027] When using this high-cleanliness double-layer membrane structure with high elasticity, the upper and lower shells are first connected and locked using the outer buckles. For membrane fixation, an optimized process is employed: the double-layer membranes are first fixed, then fused and the outer layer is removed, leaving only the inner layer. This ensures membrane stability while reducing potential contaminants by removing the outer layer, thus guaranteeing the cleanliness of the membrane chamber's interior.

[0028] During the operation of the snap-fit ​​structure, since the friction points of the shell and the snap are all located on the outside of the box, the debris, particles and other contaminants generated by friction during the snap-fit ​​and opening of the box will be isolated outside the box and will not enter the box, thus effectively protecting the clean environment inside the box.

[0029] From a material performance perspective, the upper and lower shells, made of high-purity, high-transmittance optical-grade polycarbonate, possess excellent light transmittance and strength, providing stable structural support for the membrane capsule. Simultaneously, its high purity and low volatility reduce the release of impurities and organic matter. The buckles, made of metallocene high-purity polypropylene, also exhibit low volatility, further reducing contamination of the capsule's internal environment. The use of low-particle clean membranes reduces particle generation at the source, ensuring a high level of cleanliness within the membrane capsule.

[0030] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
