Description

Technical Field

[0001] This utility model belongs to the field of lunch box technology, and in particular relates to a modular lunch box. Background Technology

[0002] In today's fast-paced life, portable lunch boxes have become an important tool for people to carry their daily meals. They are widely used by office workers to bring their own meals, students to bring their own lunches, and for outdoor picnics. As consumers' requirements for food insulation, ease of use, and hygiene continue to increase, modular lunch boxes, which can take into account both insulation and portioning functions, have gradually become one of the mainstream products in the market.

[0003] However, existing modular lunch boxes still have significant inconveniences in practical use. For example, most products currently have a tight-fitting design between the inner liner and the insulated shell to ensure good heat retention, but this also makes it difficult to remove the inner liner. When users need to take out the inner liner to eat, they often have to hold the edge of the inner liner with both hands and pull upwards forcefully. If the inner liner contains a lot of food or soup, it is very easy to slip and spill food, which not only affects the dining experience but also poses a hygiene risk. This method of operation is even more difficult for children, the elderly, or users with weak hand strength, and may even cause the lunch box to tilt or burn due to improper force. Utility Model Content

[0004] This utility model provides a modular lunch box, which aims to solve the problem of difficulty in removing the inner liner caused by the tight fit between the inner liner and the insulation shell in current modular lunch boxes.

[0006] Preferably, the storage mechanism includes: a placement slot formed on the box lid; symmetrically fixed blocks in the placement slot for holding chopsticks; and a cover plate on the box lid for covering the placement slot.

[0007] Preferably, plugs are fixed on both sides of the lid, and inserts for inserting the plugs are fixed on both sides of the insulated box.

[0008] Preferably, both the cover plate and the box lid are provided with magnets, and the corresponding magnets can attract each other.

[0009] Preferably, the cover plate has a groove, a lifting block is fixed in the groove, and the lifting block has a through opening.

[0010] Preferably, a partition plate is provided inside the inner liner, and guide grooves are symmetrically formed on the inner wall of the heat preservation box, the guide grooves being adapted to the mounting block.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a modular lunch box, such as Figure 1-5 As shown, the modular lunchbox includes: an insulated box 1; an inner liner 2 disposed inside the insulated box 1; mounting blocks 3 symmetrically fixed on both sides of the inner liner 2; a lifting frame 4 hinged to the mounting blocks 3, the lifting frame 4 being provided with a gripping sleeve 5; a detachable lid 6 disposed on the insulated box 1; and a storage mechanism disposed on the lid 6 for storing tableware.

[0022] In this embodiment, when using the combined lunch box, when it is necessary to take out the inner liner 2 for eating, the user can lift the lifting frame 4 upwards by gripping the sleeve 5 to take out the inner liner 2 from the insulated box 1. After completing the take-out and put-out operation, the lifting frame 4 can be flipped to contact the table to increase the contact surface.

[0023] After the lifting rack 4 flips over and contacts the table, it increases the contact area between the inner liner 2 and the table, making the inner liner 2 more stable when placed on the table, reducing the possibility of tipping over, and making it easier for users to operate during the meal.

[0024] This modular lunchbox, with its carrying rack 4 and grip sleeve 5, changes the traditional method of pulling the inner container by holding the edge with both hands, reducing the difficulty of removing the inner container 2, minimizing hand slippage and food spillage, and improving ease of operation. At the same time, the design of the carrying rack 4, which increases the contact surface after flipping, further enhances the stability of the inner container 2 when placed, improving its reliability during use.

[0025] In a further preferred embodiment of the present invention, the storage mechanism includes: a placement groove 7 formed on the box cover 6; a locking block 8 symmetrically fixed in the placement groove 7 for holding chopsticks 17; and a cover plate 9 provided on the box cover 6 for covering the placement groove 7.

[0026] In this embodiment, when using the storage mechanism, the user can open the cover plate 9, place the chopsticks 17 in the placement slot 7, and use the symmetrically fixed locking blocks 8 to hold the chopsticks 17 in place. Then, close the cover plate 9 to cover the placement slot 7, thus completing the storage of tableware.

[0027] The locking block 8 can limit the chopsticks 17 and prevent them from moving around freely in the placement slot 7; after the cover plate 9 covers the placement slot 7, it can reduce the contamination of the chopsticks 17 by external dust and prevent the chopsticks 17 from falling out of the placement slot 7.

[0028] The storage mechanism provides a dedicated storage space for chopsticks 17, separating tableware from food and improving the cleanliness of the lunchbox. Furthermore, the combination of the clips 8 and the cover 9 enhances the stability and hygiene of tableware storage, making it convenient for users to access tableware at any time.

[0029] In a further preferred embodiment of the present invention, plugs 13 are fixed on both sides of the box cover 6, and insert shells 14 into which the plugs 13 can be inserted are fixed on both sides of the insulated box 1.

[0030] In this embodiment, when closing the lid 6, the user can align the plugs 13 on both sides of the lid 6 with the inserts 14 on both sides of the insulation box 1 and insert the plugs 13 into the inserts 14 to connect and fix the lid 6 to the insulation box 1; when it is necessary to open the lid 6, external force is applied to make the plugs 13 come out of the inserts 14, and the lid 6 can be removed.

[0031] After the plug 13 is inserted into the housing 14, it can fix the lid 6 and prevent the lid 6 from falling off during carrying or use. The cooperation structure between the housing 14 and the plug 13 is simple, which makes it easy for users to quickly complete the closing and opening of the lid 6.

[0032] In a further preferred embodiment of this utility model, both the cover plate 9 and the box cover 6 are provided with magnet blocks 15, and the corresponding magnet blocks 15 can attract each other.

[0033] In this embodiment, when it is necessary to close the placement slot 7, the cover plate 9 can be placed on the box cover 6, so that the cover plate 9 and the magnet block 15 on the box cover 6 approach each other and attract each other, thus completing the closure of the cover plate 9; when it is necessary to open the placement slot 7, an external force is applied to separate the cover plate 9 from the box cover 6, the attraction force of the magnet block 15 is overcome, and the cover plate 9 can be opened.

[0034] After the magnets 15 attract each other, they can fix the cover 9 in place, preventing the cover 9 from opening on its own during the carrying or moving of the lunch box; at the same time, the attraction of the magnets 15 makes the opening and closing of the cover 9 smoother.

[0035] In a further preferred embodiment of the present invention, a groove 10 is provided on the cover plate 9, a lifting block 11 is fixed in the groove 10, and a through opening 12 is provided on the lifting block 11.

[0036] In this embodiment, when opening the cover 9, the user can insert their finger into the groove 10, hold the opening 12 on the lifting block 11, and apply a pulling force to separate the cover 9 from the box lid 6, thus completing the opening of the cover 9; when closing the cover 9, release the lifting block 11 so that the cover 9 naturally closes on the box lid 6.

[0037] The groove 10 provides space for the fingers to apply force, making it easy for the fingers to contact the lifting block 11; the opening 12 on the lifting block 11 allows the fingers to pass through or hold it, making the force applied when pulling the cover plate 9 more stable and preventing slippage.

[0038] In a further preferred embodiment of this utility model, a partition plate 16 is provided inside the inner liner 2, and guide grooves are symmetrically provided on the inner wall of the heat preservation box 1, the guide grooves being adapted to the mounting block 3.

[0039] In this embodiment, the partition plate 16 can divide the interior of the inner liner 2 into multiple independent spaces, making it convenient to hold different kinds of food; when the inner liner 2 is placed into the insulated box 1, the mounting blocks 3 on both sides of the inner liner 2 are aligned with the guide groove on the inner wall of the insulated box 1, and the inner liner 2 is pushed along the guide groove so that the inner liner 2 is placed smoothly into the insulated box 1.

[0040] The divider 16 enables the categorized storage of meals, reducing mixing between different meals; the guide groove is compatible with the mounting block 3, which guides the insertion and removal of the inner liner 2, preventing the inner liner 2 from shifting during operation.

[0041] In a further preferred embodiment of the present invention, a limiting groove is provided on the top inner wall of the box cover 6, and the limiting groove is adapted to the gripping sleeve 5.

[0042] In this embodiment, when closing the lid 6, the carrying frame 4 must first be flipped and reset so that the gripping sleeve 5 is in the appropriate position. Then, the lid 6 is placed on the insulated box 1 so that the gripping sleeve 5 is embedded in the limiting groove on the inner wall of the top of the lid 6, thus completing the closing and fixing of the lid 6. The limiting groove is compatible with the gripping sleeve 5 and can limit the carrying frame 4 to prevent the carrying frame 4 from shaking randomly during the carrying of the lunch box.

[0043] In summary, compared with related technologies, the design of the lifting frame 4 and the gripping sleeve 5 facilitates the removal of the inner liner 2 from the insulated box 1, reducing operational difficulty; the lifting frame 4 increases the contact surface after flipping, enhancing the stability of the inner liner 2; the storage mechanism separates tableware and food, improving cleanliness and hygiene; the plug 13 and the insert shell 14 cooperate to ensure a secure connection between the lid 6 and the insulated box 1; the magnetic block 15 makes the lid 9 open and close smoothly and prevents it from opening on its own; the groove 10, the lifting block 11, and the opening 12 facilitate the opening of the lid 9; the divider 16 enables the classified storage of food, and the guide groove and the mounting block 3 cooperate to ensure the smooth placement and removal of the inner liner 2; the limiting groove and the gripping sleeve 5 reduce the shaking of the lifting frame 4.
