Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a blister box. Background Technology
[0002] For medical device packaging, especially for biodegradable products and products highly sensitive to oxygen and moisture, the initial packaging design is particularly important and needs to meet the following requirements: 1) The structural design should be able to support and protect the product and have stability to ensure that the product is not damaged or deformed throughout its shelf life; 2) It should block oxygen, moisture, and light to protect the performance of biodegradable products; 3) It should be resistant to various sterilization processes.
[0003] In existing technologies, degradable products have limited tolerance to sterilization processes; irradiation sterilization cannot use excessively high doses, and ethylene oxide sterilization generates high temperature and humidity. Therefore, existing packaging for degradable products includes the following:
[0004] 1) Pack the degradation product and its auxiliary products separately. The degradation product is sterilized separately using low-dose irradiation, and the auxiliary products are sterilized separately using appropriate methods. This packaging method results in complex packaging for each product set, high cost, and high sterilization efficiency at a low cost.
[0005] 2) After packing the biodegradable product and its auxiliary products into a blister pack, seal it with Tyvek, and then sterilize it together with ethylene oxide. Shortly after sterilization, pack it together again in an aluminum foil bag with desiccant and oxygen absorber. This packaging method requires precise timing, which is not conducive to production scheduling. It also involves two packaging processes, resulting in high packaging costs. Furthermore, the high heat and humidity generated during ethylene oxide sterilization can affect the lifespan of the biodegradable product.
[0006] 3) Pack the biodegradable product and its auxiliary products together in a blister pack, then cover it with an aluminum foil bag, and sterilize them together with low-dose irradiation. This packaging method greatly reduces costs, but because the biodegradable product and auxiliary products are placed in the same blister pack, the internal volume of the blister pack is relatively large, the internal air passage design is insufficient, the gas inside the blister pack cannot be effectively replaced, and the retention of water and oxygen will affect the lifespan of the biodegradable product.
[0007] In addition, when using blister packaging, the outer edge of the blister box is usually stretched to its highest point to support the horizontal placement of the blister box. If the product inside the blister box is too large, and the outer edge of the blister box is stretched too far, it will cause the stretch to become thin and easily deformed. Therefore, there are problems with insufficient structural stability and inability to use products with large structural differences. Utility Model Content
[0008] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a blister box that can effectively replace the gas inside the box and reduce the impact of water and oxygen on the lifespan of the products packaged in the blister box.
[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0010] This utility model provides a blister box, including a box body. The interior of the box body has a main slot for loading the main product, an auxiliary slot for loading the auxiliary product of the main product, a secondary slot for loading the desiccant and oxygen absorber, and an airflow channel for gas to flow through the box body. The airflow channel connects the main slot, the auxiliary slot and the secondary slot to form a continuous airflow channel. The airflow channel has an air inlet and an air outlet that respectively penetrate the box body.
[0011] Preferably, there are multiple auxiliary card slots, each used to load different auxiliary products.
[0012] Preferably, the airflow channel includes multiple airflow paths connecting the air inlet and the air outlet, and the multiple airflow paths are connected in parallel.
[0013] Preferably, each airflow path passes through at least two of the main slot, auxiliary slot, and sub-slot.
[0014] Preferably, the air inlet and air outlet are located at opposite ends of the box along its length.
[0015] Preferably, one side of the box has a protrusion that extends outward from the box, and the protrusion is used to support the box when placed horizontally.
[0016] Preferably, there are multiple protrusions, which are arranged at intervals along the length of the box.
[0017] Preferably, the protrusion forms a cavity inside the box body, and a main slot, auxiliary slot, secondary slot, or airflow groove is formed inside the cavity.
[0018] Preferably, the airflow channel is any one or a combination of straight pipe type airflow channel, flat airflow channel, wavy airflow channel and honeycomb vent type airflow channel.
[0019] Compared with the prior art, this utility model has significant progress:
[0020] This utility model's blister pack enables integrated packaging and sterilization of the main product and its auxiliary products, simplifying operation steps and reducing packaging costs. It can meet the requirements of low-dose irradiation sterilization, reducing the impact on the lifespan of the main product, eliminating the need for secondary packaging, and further reducing packaging costs. In particular, by setting airflow channels inside the box to connect the main card slot, auxiliary card slot, and secondary card slot to form a continuous airflow channel, the gas inside the box can be effectively replaced, avoiding water and oxygen retention inside the box, thereby reducing the impact of water and oxygen on the lifespan of the main product.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0042] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0043] like Figure 1 and Figure 2 The image shows an embodiment of the blister box provided by this utility model.
[0044] See Figure 1 The blister box in this embodiment includes a box body 1, and the interior of the box body 1 has a main slot 2, an auxiliary slot 3, a secondary slot 4, and an airflow channel 5.
[0045] The main slot 2 is used to load the main product 100. The main product 100 can be a biodegradable product, that is, a biodegradable product that is highly sensitive to oxygen and moisture.
[0046] The auxiliary slot 3 is used to load the auxiliary product 200 of the main product 100. The main product 100 is usually equipped with the auxiliary product 200 as an accessory to assist in the use of the main product 100. For example, some auxiliary products 200 equipped with the main product 100 include a conveyor 201 and multiple auxiliary devices 202, etc.
[0047] Sub-slot 4 is used to load desiccant and oxygen absorber 300. The desiccant and oxygen absorber 300 serve to dry and remove oxygen within the housing 1.
[0048] The airflow channel 5 allows gas to circulate within the box 1. The airflow channel 5 connects the main slot 2, auxiliary slot 3, and secondary slot 4 to form a continuous airflow channel 6. The airflow channel 6 has an inlet 61 and an outlet 62 that respectively penetrate the box 1. Through the airflow channel 6, gas inside the box 1 can be quickly expelled when a vacuum is evacuated, and the inert gas inside the box 1 can be evenly distributed when inert gas is introduced, thus achieving effective gas replacement within the box 1.
[0049] It is understood that the box body 1 is an openable and closable structure to allow for the loading and unloading of the main product 100, auxiliary product 200, desiccant, and oxygen absorber 300. The box body 1 may include a box body and a box lid, with the box lid connected to the box body in an openable or closable manner. The main slot 2, auxiliary slot 3, and secondary slot 4 are preferably located on the box body, and the airflow channel 5 may be located on the box body and / or the box lid. The blister pack, used as a support packaging box, is first separated from the box body. Box body 1 is opened, exposing the main slot 2, auxiliary slot 3, and secondary slot 4 for loading the main product 100, auxiliary product 200, desiccant, and oxygen absorber 300. After loading, the lid is fastened to the box body, closing box body 1 and covering the main slot 2, auxiliary slot 3, and secondary slot 4, thus sealing the main product 100, auxiliary product 200, desiccant, and oxygen absorber 300 inside box body 1. Then, an aluminum foil bag is placed over the blister pack body 1 for sealing using existing packaging equipment. This includes vacuuming the inside of box body 1 through the air inlet 61 and outlet 62 of the airflow channel 6, filling the box body 1 with inert gas, and sealing the aluminum foil bag. This completes the combined packaging of the main product 100 and its auxiliary product 200 using the blister pack. Finally, the packaged blister pack and aluminum foil bag are subjected to low-dose irradiation sterilization.
[0050] Therefore, the blister pack of this embodiment can achieve integrated packaging and sterilization of the main product 100 and its auxiliary product 200, simplifying the operation steps and reducing packaging costs; it can meet the requirements of low-dose irradiation sterilization, reducing the impact on the lifespan of the main product 100, eliminating the need for secondary packaging and reducing packaging costs; in particular, by setting an airflow channel 5 inside the box body 1 to connect the main card slot 2, auxiliary card slot 3 and secondary card slot 4 to form a continuous airflow channel 6, the gas inside the box body 1 can be effectively replaced, avoiding water and oxygen retention inside the box body 1, thereby reducing the impact of water and oxygen on the lifespan of the main product 100.
[0051] In this embodiment, the location of the airflow groove 5 inside the box 1 can be optimized in combination with the locations of the main slot 2, auxiliary slot 3, and secondary slot 4. This design aims to prevent displacement of the main product 100, auxiliary product 200, desiccant, and oxygen absorber 300 loaded in the main slot 2, auxiliary slot 3, and secondary slot 4, while also ensuring that the airflow groove 5 connects the main slot 2, auxiliary slot 3, and secondary slot 4 to form a continuous airflow channel 6 that runs through the entire box 1, thus guaranteeing the gas replacement effect inside the box 1.
[0052] In this embodiment, the airflow slot 5 is preferably any one or a combination of straight pipe airflow slots, flat airflow slots, corrugated airflow slots, and honeycomb-shaped vent airflow slots. The cost of straight pipe airflow slots, flat airflow slots, corrugated airflow slots, and honeycomb-shaped vent airflow slots increases sequentially, but the airflow uniformity also increases sequentially. Therefore, a suitable selection can be made according to actual needs.
[0053] In this embodiment, preferably, the box body 1 has multiple auxiliary slots 3, which are used to load different auxiliary products 200, such as conveyors 201 and multiple auxiliary tools 202. The airflow channel 5 connects the main slot 2, the multiple auxiliary slots 3 and the secondary slots 4 to form a continuous airflow channel 6.
[0054] In this embodiment, preferably, the airflow channel 6 includes multiple airflow paths 7 connecting the air inlet 61 and the air outlet 62. These multiple airflow paths 7 are connected in parallel, thus allowing multiple airflow paths 7 to traverse the entire housing 1, ensuring gas flow throughout the housing 1 and achieving an overall gas displacement effect. More preferably, each airflow path 7 passes through at least two of the main slot 2, auxiliary slot 3, and secondary slot 4 to ensure gas flow at the main slot 2, auxiliary slot 3, and secondary slot 4.
[0055] In this embodiment, preferably, the air inlet 61 and air outlet 62 of the airflow channel 6 are located at the two ends of the length direction of the box body 1. The box body 1 is roughly rectangular, and the length direction of the box body 1 refers to the direction of extension of the long side of the roughly rectangular box body 1. By placing the air inlet 61 and air outlet 62 of the airflow channel 6 at the two ends of the length direction of the box body 1, the airflow channel 6 can penetrate the entire box body 1 to the maximum extent, thereby ensuring the overall gas replacement effect inside the box body 1. It should be noted that the two ends of the length direction of the box body 1 refer to the two ends in the airflow space, not the two absolute endpoints of the box body 1.
[0056] See Figure 2 In this embodiment, preferably, a protrusion 8 is formed on one side of the box body 1, protruding outwards. The protrusion 8 is used to support the horizontal placement of the box body 1, that is, the protrusion 8 serves as a horizontal support for the box body 1, allowing the box body 1 to be placed stably on a work surface (such as a desktop). Compared to the prior art where the outer edge of the blister box is stretched to its highest point as a horizontal support for the blister box, this embodiment places the protrusion 8, which serves as a horizontal support, on one side of the box body 1. This makes the box body 1 less prone to deformation, effectively improving the structural stability of the box body 1 and reducing the risk of deformation that could threaten the structure of the product loaded inside the blister box, thus better protecting the product loaded inside the blister box.
[0057] Preferably, multiple protrusions 8 are provided, and the multiple protrusions 8 are arranged at intervals along the length direction of the box body 1, thereby forming a multi-point support structure, which can further improve the resistance to deformation. In a preferred embodiment, such as Figure 2As shown, three protrusions 8 can be arranged at intervals of left, middle and right along the length direction of the box body 1 to form a "three-high-point support" structure, which can make the whole box body 1 have good anti-deformation ability and horizontal placement support stability.
[0058] Preferably, a concave cavity is formed inside the box body 1 by the protrusion 8, and a main card slot 2, an auxiliary card slot 3, a secondary card slot 4 or an air flow slot 5 is formed in the concave cavity. That is, the protrusion 8 is designed in combination with the main card slot 2, the auxiliary card slot 3, the secondary card slot 4, the air flow slot 5 and the air flow channel 6 inside the box body 1. When there are multiple protrusions 8, the larger auxiliary product 200 can be arranged in the concave cavity formed inside the box body 1 by the protrusion 8 located at the edge position of the box body 1, the heavier desiccant and oxygen absorber 300 can be arranged in the concave cavity formed inside the box body 1 by the protrusion 8 located at the middle position of the box body 1, and the main product 100 can be arranged in the concave cavity formed inside the box body 1 by the protrusion 8 closer to the protrusion 8 corresponding to the desiccant and oxygen absorber 300. In addition, the longer auxiliary product 200 can be placed obliquely in the box body 1 to maintain balance, and the rest of the lighter and smaller auxiliary products 200 can be placed in the auxiliary card slot 3 at a suitable position, so that the overall weight of the box body 1 is balanced after loading and it is convenient to place and take.
[0059] In this embodiment, preferably, all the corner positions on the outer contour surface of the box body 1 are transitioned to semi-circular arcs, and all the edge positions are smoothed, so as to prevent piercing the aluminum foil bag when putting on the outer aluminum foil bag.
[0060] In this embodiment, preferably, the material of the box body 1 is preferably PETG (polyethylene terephthalate-1,4-cyclohexanedimethanol ester), which is a transparent, non-crystalline copolyester and is a light blue transparent material. The material thickness is mostly between 0.5 mm and 1.0 mm, suitable for irradiation sterilization. The sheet material can select a suitable thickness according to factors such as the weight of the packaged product and the deformation amount during the forming of the blister box.
[0061] In this embodiment, the width design of the aluminum foil bag supporting the box body 1 needs to ensure that the box body 1 can be smoothly loaded and taken out. Preferably, the width of the aluminum foil bag is the sum of the width of the box body 1, the height of the box body 1 and the reserved width, and the reserved width is 1 cm - 3 cm. The length design of the aluminum foil bag needs to leave a space for the air nozzle of the packaging equipment to enter and seal the edge after the box body 1 is loaded, so as to ensure that the aluminum foil bag is not damaged when the packaging equipment evacuates and inhales air. Preferably, the length of the aluminum foil bag is the sum of the depth of the air nozzle entering, half of the height of the box body 1 and the reserved length, and the reserved length is 1 cm - 3 cm.
[0062] In this embodiment, the aluminum foil bag is preferably made of a three-layer composite material. The outermost layer is nylon, which primarily prevents punctures and moisture penetration, has excellent flexibility, and is also easy to apply ink with strong ink adhesion, resulting in vibrant colors that are not easily peeled off and a long lifespan. The second layer is aluminum foil, a metallic material that effectively isolates oxygen, moisture, and light. The innermost layer is polyethylene, which blocks moisture and oxygen penetration and provides good heat-sealing performance. To better ensure the safety and effectiveness of the aluminum foil bag, the appropriate thickness of the material layers can be selected based on the size of the aluminum foil bag and the weight of the packaged product.
[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
