Abstract
Description
Technical Field
[0001] This utility model relates to the field of outdoor insulated boxes, and in particular to a telescopic outdoor insulated box. Background Technology
[0002] Outdoor insulated boxes are portable containers used to maintain the stable temperature of food, beverages, and other items. They achieve long-lasting heat or cold retention through insulation materials and a sealed design. Primarily used in outdoor settings (such as camping, picnics, and road trips) to maintain food freshness, they also feature a cooling function, with some models supporting both cooling and warming. Capacities range from 8.5L (approximately 12 bottles of beverage) to 26L (approximately 30 bottles of beverage).
[0003] According to our company's past sales data for insulated boxes, 5-8 liter capacity is the main sales driver. However, user surveys indicate that overseas users consider 8 liters to be too small. To meet user demand for "larger capacity," manufacturers / sellers must produce larger insulated boxes. This directly leads to larger packaging volume, higher warehousing costs, and lower transportation efficiency (smaller quantities shipped per trip), ultimately driving up overall logistics costs. Furthermore, if users purchase a large-capacity, fixed-size insulated box, it will be very bulky and take up valuable storage space when there are few users or when a large capacity is not needed, causing inconvenience and waste.
[0004] Furthermore, existing insulated boxes have fixed internal and external volumes when not in use, resulting in significant waste of transportation space and limiting their application scenarios. A 12L insulated box might be too large for a short trip for 2-3 people, while it might be too small for a family gathering of 5-6 people. Users often need to prepare boxes of different sizes for different scenarios or compromise on "inappropriate" capacities.
[0005] Therefore, this utility model proposes a telescopic outdoor insulated box. Utility Model Content
[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a telescopic outdoor insulated box.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic outdoor insulated box, comprising an upper outer shell, a top cover snapped onto the top of the upper outer shell, an upper inner liner fixedly connected inside the upper outer shell, a lower outer shell slidably connected inside the upper inner liner, and a lower inner liner fixedly connected inside the lower outer shell.
[0008] Furthermore, the outer surface of the upper body shell is symmetrically and rotatably connected with fixing buckles on both sides, and the top of each of the two fixing buckles is fixedly connected with a second handle. The top of the outer surface of the lower body shell is symmetrically provided with slots that match the bottom of the fixing buckles.
[0009] Furthermore, the top of the upper inner liner is symmetrically fixed with locking blocks, and the outer surfaces of both locking blocks are engaged with the bottom sidewall of the upper cover.
[0010] Furthermore, the top of the outer surface of the upper body shell is symmetrically and rotatably connected with a shell handle.
[0011] Furthermore, a sealing strip is provided between the bottom outer ring of the upper inner liner and the top outer ring of the lower inner liner, and the sealing strip is adhered to the top side wall of the lower inner liner.
[0012] Furthermore, a lower base is fixedly connected to the bottom of the lower body shell, and several anti-slip textures are provided on both ends of the upper surface of the lower base.
[0013] Furthermore, the top of the cover is symmetrically rotatably connected to a first handle, and the top sidewall of the cover is symmetrically provided with mounting grooves that match the first handle.
[0014] This utility model has the following beneficial effects:
[0015] This utility model, in use, features a telescopic outdoor insulated box. Through its upper outer shell, upper inner liner, lower outer shell, lower inner liner, and fixing buckles, the telescopic design creatively separates the "usage state" from the "storage / transportation state." This reduces packaging volume and transportation costs while meeting users' needs for larger product capacity. This means that more products can be loaded onto the same container, warehouse, or truck, significantly reducing logistics and warehousing costs per unit. Furthermore, when stored in the kitchen, garage, or trunk, the retracted size is far smaller than a fixed 13L or even 12L box, greatly improving the convenience of home storage. Moreover, its versatility allows users to freely adjust the capacity according to their actual needs, truly realizing a single product covering multiple usage scenarios, enhancing product practicality and user value.

[0022] Figures 1 to 5 As shown, a telescopic outdoor insulated box is disclosed, comprising an upper outer shell 1, a top cover 4 snapped onto the top of the upper outer shell 1, an upper inner liner 2 fixedly connected to the inside of the upper outer shell 1, a lower outer shell 7 slidably connected to the inside of the upper inner liner 2, and a lower inner liner 8 fixedly connected to the inside of the lower outer shell 7. The interlayer between the upper outer shell 1 and the upper inner liner 2, and between the lower outer shell 7 and the lower inner liner, shall be filled with liquid internal foam or solid foam to achieve the insulation effect of the entire box.
[0023] Specifically, the outer surfaces of the upper body shell 1 are symmetrically connected to two retaining buckles 12, each retaining buckle 12 has a second handle 13 fixedly connected to its top. The top of the outer surface of the lower body shell 7 is symmetrically provided with slots 14 that match the bottom of the retaining buckles 12. When the bottom of the retaining buckle 12 is inserted into the slot 14, as... Figure 4 As shown, the entire insulated box is in an extended state, and both the upper inner liner 2 and the lower inner liner 8 can hold items. Conversely, by simply rotating the fixing buckle 12 and engaging it with the slot 14, the upper outer shell 1 can be pressed down, and the lower outer shell 7 can be retracted into the upper inner liner 2.
[0024] Among them, the top of the upper inner liner 2 is symmetrically fixed with a locking block 3, and the outer surface of the two locking blocks 3 are engaged with the bottom side wall of the upper cover 4. The upper outer shell 1 and the upper cover 4 are engaged through the engagement of the locking blocks 3 with the side wall of the upper cover 4, so as to realize the assembly between the two. The locking blocks 3 should be made of the elastic locking block material in the existing technology, and use their own slight deformation to achieve engagement with the side wall of the upper cover 4.
[0025] The top of the outer surface of the upper shell 1 is symmetrically connected with two shell handles 6. The two shell handles 6 can be used as gripping parts when the entire insulated box is moved. When the two shell handles 6 are rotated inward, they can form a triangular structure with the upper shell 1 itself, making it more stable to lift.
[0026] A sealing strip 9 is abutted between the bottom outer ring of the upper inner liner 2 and the top outer ring of the lower inner liner 8. The sealing strip 9 is also adhered to the top side wall of the lower inner liner 8. The presence of the sealing strip 9 can ensure the airtightness between the upper inner liner 2 and the lower inner liner 8, reduce the heat exchange between the outside air and the inside of the heat preservation box, and thus ensure a better heat preservation effect.
[0027] The bottom of the lower outer shell 7 is fixedly connected to the lower base 10. Several anti-slip textures 11 are provided on both ends of the upper surface of the lower base 10. By stepping on the anti-slip textures 11 of the lower base 10 and then pulling the upper outer shell 1 upwards with your hands, the entire insulated box can be stretched to the extended state more easily.
[0028] The top of the cover 4 is symmetrically connected to a first handle 5, and the top side wall of the cover 4 is symmetrically provided with mounting grooves that match the first handle 5. The presence of the first handle 5 makes it easy to grasp the first handle 5, thereby pulling upwards to open the cover 4 and expose the inner liner 2.
[0029] In actual production, the extended dimensions of the insulated box of this application are 416X300X236mm (approximately 29.67L), the collapsed dimensions are 416X300X153mm (approximately 19.23L), and the packaging dimensions are 405X286X153mm (approximately 17.72L). The actual collapsed capacity is 5L, and the maximum usable capacity is 13L. In contrast, the existing 12L insulated box has dimensions of 350X260X250mm (approximately 23.4L). The new design of this application saves approximately 24.36% of space compared to the current model. Eleven 330ml cans can be placed in the lower layer, and eight more cans can be placed in the upper layer after the extension.
[0030] Meanwhile, considering that users who are sensitive to space are generally small families or single individuals, this design style leans more towards a family-oriented and approachable aesthetic. The color scheme also features more low-saturation hues, creating a more welcoming and friendly atmosphere, appealing to families and fashionable women alike, and making photos look better on female users. It's compact, space-saving, and minimalist with soft colors and clean lines. Furthermore, considering that small families may have children, rounded corners and environmentally friendly materials are used, ensuring safety.
[0031] When using the telescopic outdoor insulated box, to extend the upper shell 1, press down the opening positioning buckle, step on the anti-slip texture 11 of the base 10, and hold the second handle 13 on both sides to pull up the fixing buckle 12 to the upper shell 1. After it is in place, rotate the fixing buckle 12 to fasten its bottom with the slot, so that the upper shell 1 is fastened tightly when it is unfolded. Conversely, when retracting, simply rotate the fixing buckle 12 in the opposite direction and then press down the upper shell 1.
[0032] The existing 12L insulated box has a packaging size of approximately 23.4L, while the new design in this application, when shrunk, has a packaging size of only 17.72L, saving approximately 24.36% of space. This means that a larger quantity of products can be loaded onto the same container, warehouse, or truck, significantly reducing the logistics and warehousing costs per unit of product.
[0033] Meanwhile, when users store the insulated box in the kitchen, garage, or trunk, its folded size is much smaller than a fixed 13L or even 12L box, greatly improving the convenience of home storage. This versatility allows users to adjust the capacity according to their actual needs, truly making one product cover multiple usage scenarios and enhancing its practicality and user value.
[0034] As an efficient space utilization solution, telescopic structures maximize space efficiency throughout the entire product lifecycle (from the factory to the user's home).
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. 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.
