Multi-plate integrated packaging structure for preventing prefabricated glue from being dried

Abstract

According to the prefabricated glue multi-plate integrated packaging structure, through the vertical arrangement design of glue plates, a gel area is directionally immersed in a small amount of moisturizing liquid, and through cooperation with a repeated sealing zipper, drying prevention and convenient taking are achieved. The multi-plate co-bag scheme reduces the packaging cost by more than 60%, the compact stacking structure improves the impact resistance, and the multi-plate co-bag structure is suitable for a large-scale production scene.

Description

Technical Field

[0001] The present invention relates to the technical field of biological experiment consumable packaging, and specifically to an anti-drying multi-board integrated packaging structure for PAGE precast gels. Background Art

[0002] There are four major defects in the existing precast gel packaging: Large amount of moisturizing liquid used: Single-board independent packaging requires filling a large amount of moisturizing liquid (occupying ≥ 30% of the bag volume) to prevent the gel from shrinking, resulting in high costs. Easy deformation of the gel plate: Long-term pressure in vacuum packaging causes the gel plate to warp. Low production efficiency: Single-board independent bagging, filling with moisturizing liquid, and sealing processes are cumbersome.

[0003] Easy damage to the gel plate during transportation and storage: Both sides of the gel plate are subject to external impacts, causing the gel to separate from the support plate. Summary of the Invention

[0004] Object of the Invention To provide an integrated packaging solution to simultaneously solve the problems of moisturizing efficiency, impact resistance, and cost control in multi-board packaging. Technical Solution

[0005] As Figure 1 shown, the packaging structure includes: Bag packaging body: Made of PET / PE composite film, with internal dimensions adapted to stack 12 gel plates. Vertical positioning design: After the gel plates are loaded, they are constrained by the bag body to be in a vertical state, and the comb end is immersed in the bottom moisturizing liquid. Top operation opening: A tear strip (2) and a repeat seal zipper (3) are sequentially provided. Observation window (4): The light-transmitting area on the side wall is ≥ 20%, for real-time monitoring of the liquid level and the state of the gel plate. Advantageous Effects

[0006] Improved moisturizing efficiency: The vertical immersion design reduces the amount of moisturizing liquid used to less than 30% of that in single-board packaging. Optimized comprehensive cost: The 12-board co-bag solution reduces the packaging material cost by more than 60%. The integrated packaging time ≈ the single-board packaging time. Enhanced transportation protection: Multiple boards are closely arranged to form a mechanical buffer unit, enhancing transportation protection. Operational convenience: The repeat seal zipper (3) supports multiple openings and closings, and the remaining gel plates have a storage period of ≥ 30 days. Description of the Drawings

[0007] Figure 1 : Schematic diagram of the three-dimensional structure of the packaging structure Heat-sealed edge; 2 - Tear strip; 3 - Re-sealable zipper; 4 - Observation window; 5 - Humidity retention liquid level indicator line; 6 - Lowest position of the humidity retention liquid Specific implementation method

[0008] Place 12 prefabricated rubber plates (including residual gel between the plates) into the packaging bag → Inject humidity retention liquid to the liquid level indicator line (5) → Seal the heat-sealed edge area (1). Note: Retaining the residual gel can enhance the adhesion between the plates and improve the efficiency by eliminating the removal process.

[0009] Transportation and storage: The gel between the plates adheres to form an integral buffer structure to disperse external impacts; The bag forces the rubber plates to be stored vertically to ensure that the comb end is continuously immersed in the humidity retention liquid.

[0010] User operation: Tear off the tear strip (2) → Unzip the seal zipper (3) → Push up the stack of rubber plates with one hand → Horizontally extract the target rubber plate with the other hand → Press to close the zipper. Note: The operation status can be monitored through the observation window (4) throughout the process.
