Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a heat-insulating and moisture-retaining cardboard box packaging. Background Technology

[0002] With the rapid development of cold chain logistics and fresh food e-commerce, the demand for packaging boxes capable of maintaining a specific temperature and humidity environment during transportation is increasing. This is especially true in the transportation of pharmaceuticals, vaccines, high-end foods, and biological agents, where the heat and humidity insulation performance of the packaging directly affects the quality and safety of the contents. Currently, a widely adopted solution is to use cardboard boxes as outer packaging, with insulated bags or linings inside to achieve temperature and humidity control.

[0003] When using this type of packaging, operators typically need to first place the items into the inner insulated bag and then seal the bag opening. Current sealing methods often rely on simple manual folding, using tape, or utilizing the bag's built-in adhesive strip. This sealing process is cumbersome, especially when packaging large quantities, severely impacting packaging efficiency.

[0004] More importantly, this simple sealing method is unreliable. In complex transportation environments, due to bumps, vibrations, or movement of contents, manually folded bag openings are prone to loosening, and adhesive tape can easily lose its stickiness and fall off in low-temperature or humid environments. Once the seal on the insulated bag fails, air convection occurs between the inside and outside, rapidly disrupting the stable temperature and humidity environment inside the bag. This significantly reduces or even completely negates the insulation and moisture retention effects, potentially leading to damage or spoilage of valuable items inside.

[0005] Therefore, this utility model proposes a heat-insulating and moisture-retaining cardboard box packaging to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome and laborious sealing operations, simple and unreliable bag locking structures, and easy loosening during transportation leading to failure of heat preservation and moisture retention in existing heat-insulating and moisture-retaining cardboard packaging, this utility model aims to provide a heat-insulating and moisture-retaining cardboard packaging with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a heat-insulating and moisture-retaining cardboard box packaging, including: an insulated box body and an insulated bag body housed inside the insulated box body. The opening of the insulated bag body is connected to a fastening mechanism. The fastening mechanism includes inner fold strips symmetrically arranged on both sides of the bag opening, a connecting strip fixedly connected to the inner side of the inner fold strips, a magnet fixed to one side of the connecting strip, a connecting groove opened on the other side of the connecting strip, and a folding strap connecting the connecting strip and the inner fold strip; a pull rope sequentially threaded through the inner fold strip and the connecting strip; and a locking component fixed to the outer wall of the insulated box body.

[0008] The locking component includes a fixing box that serves as the mounting base, a limiting block that is slidably connected inside the fixing box, and a pull cord that passes through the limiting block.

[0009] Furthermore, a spring is installed inside the fixing box. One end of the spring abuts against the inner wall of the fixing box, and the other end abuts against the limiting block. The continuous elastic force generated by the spring drives the limiting block to form a stable lock on the pull cord inserted therein, thereby fixing the position of the pull cord and preventing it from retracting and causing the bag opening to loosen.

[0010] Preferably, the locking assembly further includes a pull rod and a telescopic column. The pull rod extends movably through the fixing box and is fixedly connected to one end of the telescopic column. The other end of the telescopic column is fixedly connected to the limiting block. A spring is sleeved on the outer periphery of the telescopic column. The structure allows the spring to be compressed by manually pulling the pull rod, causing the limiting block to retract and release the lock on the pull cord. This facilitates precise adjustment or complete release of the sealing tightness of the bag opening.

[0011] Preferably, the tightening mechanism further includes a second pull rope, the two ends of which are fixedly connected to the connecting strips on both sides. The pull rope is used to pull the connecting strips on both sides that have been attracted together to separate them, so as to quickly open the bag opening of the insulated bag. The opened state can also be locked by the locking component to keep the bag opening open for easy access to items.

[0012] Preferably, in order to enhance the reliability of magnetic closure, an iron block that can be attracted to the magnet is fixedly embedded inside the connecting groove, ensuring the firmness of the connecting strip when closed.

[0013] Preferably, the interior of the insulated box is also equipped with a protective mechanism, which is located below and to the side of the insulated bag, providing dual protection for the internal items through physical cushioning and humidity control.

[0014] As a specific implementation of the above-mentioned protective mechanism, it includes a collection plate, which is laid on the inner bottom surface of the insulated box. The upper surface of the collection plate is integrally formed with a crisscrossing protrusion structure and groove structure. The design can not only elevate the items, but also effectively collect and drain the condensate water generated by the temperature difference, so as to prevent the items from getting wet.

[0015] As another specific implementation of the above-mentioned protective mechanism, it includes a sponge side pad attached to the inner wall of the insulated box and a sponge bottom pad laid on the bottom surface of the insulated box, wherein the sponge bottom pad is located below the collection plate, and the two together form an all-round buffer protection layer to effectively absorb external impacts.

[0016] Preferably, after the drawstring closes and locks the opening of the insulated bag, the portion of the drawstring protruding outside the locking assembly can serve as a lifting rope, providing a handle function for the entire packaging box, facilitating handling, achieving multiple uses in one item, and optimizing the overall structure of the packaging box.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome and laborious sealing operation of the insulated packaging bag opening in the prior art, as well as unreliable locking and easy loosening during transportation, by setting a tightening mechanism driven by a pull rope, magnetic attraction and locking, and automatic locking by a spring and limiting block. It achieves the technical effect of convenient operation, fast sealing, firm locking and effective prevention of accidental opening of the bag opening.

[0018] 2. This utility model solves the problem in the prior art where condensate from the temperature difference between the inside and outside directly soaks the internal items, especially paper-packaged items, causing them to become damp and damaged, by setting a collection plate with a concave-convex structure at the bottom of the box. It achieves the technical effect of effectively isolating the items from the condensate, realizing "humidity control" rather than "soaking in moisture", and significantly improving the storage quality of the items.

[0019] 3. This utility model solves the problem of insufficient impact resistance and cushioning performance of existing packaging boxes during transportation by setting sponge side pads and sponge bottom pads on the inner wall of the insulated box, which makes the internal items easily damaged by collision. It achieves the technical effect of providing effective cushioning protection for the internal insulated bag and the items inside, and improving the safety of storage and transportation.

[0020] 4. This utility model solves the problems of inconvenient adjustment of automatic locking devices and the need for additional handles on packaging boxes, by setting a manually pullable lever to control the unlocking of the locking component and using the pull rope for sealing as a lifting rope. It achieves the technical effect of both accurately adjusting the tightness of the bag opening and conveniently lifting the packaging box, thus improving the overall ease of use and user-friendliness.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Reference Figures 1 to 4 This utility model provides a heat-insulating and moisture-retaining cardboard box packaging, which aims to solve the problems of cumbersome sealing operation, unreliable locking, and easy soaking of internal items by condensation in the existing heat-insulating packaging.

[0025] The heat-insulating and moisture-retaining cardboard packaging includes an insulated box body 1 and an insulated bag body 2 housed inside the insulated box body 1. The opening of the insulated bag body 2 is connected to a tightening mechanism 3, and a protective mechanism 4 is also provided inside the insulated box body 1. The insulated box body 1 provides basic load-bearing capacity and outer protection for the entire device. The insulated bag body 2 is used to directly contain the items and provide the core heat-insulating and moisture-retaining environment. The tightening mechanism 3 is used to quickly close and lock the opening of the insulated bag body 2, and the protective mechanism 4 provides cushioning protection and humidity control for the items inside the insulated bag body 2.

[0026] The tightening mechanism 3 includes inner fold strips 32 symmetrically arranged on both sides of the opening of the insulated bag body 2. A connecting strip 33 is fixedly connected to the inner surface of the inner fold strip 32. The two connecting strips 33 on both sides achieve the opening and closing of the bag opening through coordinated action. A magnet 36 is fixed on one side of the connecting strip 33, and a connecting groove 37 is opened on the other side of the connecting strip 33 to cooperate with it. An iron block that can be attracted to the magnet 36 is fixedly embedded inside the connecting groove 37. When the two connecting strips 33 on both sides approach each other, the magnet 36 can be attracted into the connecting groove 37 and attracted to the iron block, thereby achieving the sealing of the bag opening. The connecting strip 33 and the inner fold strip 32 are connected by a folding band 31. The folding band 31 folds or unfolds as the inner fold strip 32 and the connecting strip 33 move to ensure the sealing integrity of the bag opening in various states.

[0027] The fastening mechanism 3 includes a pull cord 34, which is sequentially threaded through the inner folding strip 32 and the connecting strip 33. It is used to drive the two connecting strips 33 to move towards each other until the magnet 36 and the connecting groove 37 are attracted. In order to achieve reliable locking of the pull cord 34, the fastening mechanism 3 also includes a locking component 38 fixed to the outer wall of the heat preservation box 1. The locking component 38 includes a fixing box 381 as a shell. A limiting block 382 is slidably connected inside the fixing box 381. The pull cord 34 passes through the limiting block 382. A spring 385 is also provided inside the fixing box 381. One end of the spring 385 abuts against the inner wall of the fixing box 381, and the other end abuts against the limiting block 382, ​​thereby applying a continuous pushing force to the limiting block 382, ​​so that it forms a one-way locking state for the pull cord 34.

[0028] Meanwhile, to facilitate precise adjustment or unlocking, the locking assembly 38 also includes a pull rod 383 and a telescopic column 384; the pull rod 383 can be pulled through the fixing box 381 and is fixedly connected to one end of the telescopic column 384, and the other end of the telescopic column 384 is fixedly connected to the limiting block 382; the spring 385 is sleeved on the outer periphery of the telescopic column 384. When the pull rod 383 is pulled, the telescopic column 384 is compressed and the spring 385 is compressed, which drives the limiting block 382 to the unlock position, thereby releasing the lock on the pull rope 34; in addition, the tightening mechanism 3 also includes a pull rope 35. The two ends of the pull rope 35 are fixedly connected to the connecting strips 33 on both sides respectively. The pull rope 35 is used to pull the connecting strips 33 on both sides to separate them. Its stroke state can also be locked by the locking assembly 38.

[0029] The insulated box 1 is equipped with a protective mechanism 4 located below and to the side of the insulated bag 2, providing all-round protection for the insulated bag 2. The protective mechanism 4 includes a collection plate 42, which is laid on the inner bottom surface of the insulated box 1. The upper surface of the collection plate 42 is integrally formed with a crisscrossing protrusion structure and groove structure. The structure can elevate the internal items, so that condensation or moisture can be collected in the grooves to prevent the items from being directly soaked. The protective mechanism 4 includes a sponge side pad 41 attached to the inner wall of the insulated box 1 and a sponge bottom pad 43 laid on the inner bottom surface of the insulated box 1. The sponge bottom pad 43 is located below the collection plate 42, providing bottom cushioning and stable support for the collection plate 42. After the opening of the insulated bag 2 is closed, the part of the pull rope 34 that protrudes outside the locking component 38 can be used as a lifting rope to facilitate the user to lift and move the entire packaging box.

[0030] The implementation principle of this application embodiment is as follows: When using the cardboard box packaging, the object is placed inside the insulated bag body 2. By pulling the pull cord 34 in the pulling and tightening mechanism 3, the inner fold strip 32 is folded inward, causing the two connecting strips 33 to move towards each other until the magnet 36 slides into the connecting groove 37 and attracts the iron block inside the connecting groove 37, thus closing the two connecting strips 33 and completing the wrapping of the object. During the process, the force of pulling the pull cord 34 is greater than the limiting force generated by the spring 385 pushing the limiting block 382 in the locking assembly 38. This cancels the automatic sliding of the spring 385 against the limiting block 382 after the pull cord 34 is pulled, thus automatically locking the closed state of the insulated bag body 2. At the same time, the operator can manually pull the pull rod 383 inside the fixing box 381 to retract the telescopic column 384 and the spring 385, thereby manually canceling the locking of the position of the pull cord 34, which is convenient for precise adjustment of the position of the pull cord 34. Spring 385 is sleeved on the outside of telescopic column 384. Telescopic column 384 restricts the movement of spring 385. At the same time, folding strip 31 will automatically fold and unfold with the movement of connecting strip 33 and inner folding strip 32 to ensure sealing effect. Finally, the folding plate on the outside of the insulated box 1 is closed to complete the packaging of the object. At this time, the two pull ropes 34 can also act as external lifting ropes to facilitate the overall transportation of the packaging box. At the same time, the materials of the insulated box 1 and the insulated bag 2 itself keep the internal object warm and moist. When it is necessary to take out the object, by pulling pull rope 35, the two connecting strips 33 are separated from each other and finally adhere to the inner wall of the insulated bag 2. At this time, the inner folding strip 32 will automatically unfold to both sides, so that the bag opening of the insulated bag 2 is fully opened. Similarly, the locking components 38 on both sides will automatically lock the state of pull rope 35, so that the top edge of the connecting strip 33 will not obstruct the operator when taking out or putting out the object.

[0031] After the object is stored inside the packaging box, the collection plate 42 in the protective mechanism 4 is designed like the inner groove of a waffle, so that the moisture emitted by the object itself or the condensation generated during the cold insulation will flow along the raised structure into the groove below. This makes the object itself, especially if it is a paper-packaged medicine or food, "elevated" and will not be directly soaked in the condensation. This truly achieves "moisture control" rather than "soaking in moisture", which improves the storage effect. At the same time, the sponge side pads 41 and sponge bottom pads 43 on the inner wall of the insulated box 1 will cushion the object inside the insulated bag 2 when the packaging box is collided, which improves the storage effect.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
