Description

Technical Field

[0001] This utility model relates to the field of tableware technology, specifically to a lunch box. Background Technology

[0002] Lunch boxes, as a widely used daily necessity, play an important role in many situations. Especially those lunch boxes with a plastic main shell and a removable, divider stainless steel inner liner are popular with consumers due to their ease of cleaning, reasonable structure, and practical function. However, in existing technology, there are three main types of main shells for lunch boxes with dividers. One type has thinner dividing ribs, but because the stainless steel inner liner has flanges, the thinner dividing ribs cannot simultaneously support the flanges on both sides of the dividing ribs. The second type has wider dividers, which are integrally injection molded with the main shell. Due to limitations in the injection molding process, the area corresponding to the divider on the bottom of the main shell has wide and deep recesses. This not only results in an unattractive appearance but also makes it easy for dirt and grime to accumulate in the recesses during cleaning, making them difficult to clean. Furthermore, this recessed structure is easily damaged by bending; if the divider is damaged, the entire lunch box may become unusable, leading to high repair costs.

[0003] The third type involves adding an outer shell on top of the second type, which improves the aesthetics and protects the main shell. However, adding an outer shell not only increases manufacturing costs, but also makes the overall structure more complex as the outer shell needs to be connected to the main shell. Furthermore, during use, gaps can easily form between the outer shell and the main shell due to thermal expansion and contraction, which can trap dirt and grime, making them difficult to clean.

[0004] In addition, the existing partitions and the main shell are all integrally molded, which can easily create dead corners at the connection between the partitions and the main shell. These dead corners are not only difficult to clean thoroughly, but may also breed bacteria with long-term use, affecting the user's health.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] See Figures 1 to 14 As shown, this application embodiment provides a lunch box, including a bottom shell 1, a partition 2, multiple stainless steel inner liners 3, and a top cover 4. The bottom shell 1 has a cavity 101. The partition 2 is detachably connected to the bottom shell 1 and is located within the cavity 101, dividing the cavity 101 into multiple partition grooves 1011. The partition 2 has a hollow structure and is provided with a cutlery receiving groove 213. The top edge of each stainless steel inner liner 3 is provided with a rolled edge 31. Each stainless steel inner liner 3 is respectively accommodated in a corresponding partition groove 1011, and the rolled edge 31 of the stainless steel inner liner 3 is supported on the partition 2. The top cover 4 is detachably connected to the bottom shell 1 and is provided with multiple sealing rings 6. When the top cover 4 is connected to the bottom shell 1, each sealing ring 6 is respectively attached to the rolled edge 31 of the corresponding stainless steel inner liner 3.

[0025] The lunchbox provided in this application, through its unique structural design, effectively supports the stainless steel inner liner 3 while avoiding the drawbacks of traditional lunchboxes, such as unattractive appearance, easy accumulation of dirt and grime, difficulty in cleaning, and high maintenance costs associated with their partition structures. Specifically, the lunchbox of this application uses a detachable divider 2 that works in conjunction with the bottom shell 1. The hollow structure of the divider 2 and the specific extension 21 design not only provide stable support for the stainless steel inner liner 3 but also make the overall structure of the lunchbox more rational, facilitating cleaning and maintenance. Simultaneously, the detachable connection between the divider 2 and the bottom shell 1 allows for convenient partial replacement of the lunchbox when damaged, reducing maintenance costs. Furthermore, taking advantage of the wide shelf, a cutlery-holding slot 213 is provided on the divider 2 to conveniently place cutlery such as spoons and chopsticks, making the space utilization of the lunchbox more rational and its functions more diverse. In addition, the lunchbox of this application also ensures the sealing performance of the lunchbox by setting multiple sealing rings 6 on the top cover 4, effectively preventing food leakage and odor emission, thus improving the user experience.

[0026] In some possible implementations, the divider 2 includes at least one extension 21. The extension 21 extends along the length or width of the bottom shell 1 and includes two spaced-apart side plates 211 and a connecting plate 212 connecting the two side plates 211. A gap exists between the two side plates 211, and the rolled edge 31 of the stainless steel inner liner 3 is supported on the side plates 211 or the connecting plate 212. One extension 21 can divide the lunchbox into two partition slots 1011; another extension 21 can divide it into another partition slot 1011, and so on. By reasonably setting the number and position of the extensions 21, the number and layout of the partition slots 1011 inside the lunchbox can be flexibly adjusted to meet the needs of different users. For example, when multiple different types of food need to be placed, multiple extensions 21 can be set up to divide the lunchbox into multiple smaller compartments 1011, so that different foods can be stored separately to avoid cross-contamination of flavors. When larger foods need to be placed, a shelf 2 with fewer extensions 21 can be used to form a larger compartment 1011 for easy placement. In addition, this flexible and adjustable partition structure also makes the lunchbox more versatile and adaptable, easily handling scenarios such as daily meals, picnics, and travel. At the same time, the design of the extensions 21 also fully considers the support of the stainless steel inner liner 3. The two side plates 211 increase the width of the extensions 21 at intervals, and the connecting plate 212 connects the beam side plates 211 to improve the overall strength, ensuring that the stainless steel inner liner 3 is placed stably in the compartments 1011 without shaking or tilting, further improving the practicality and reliability of the lunchbox.

[0027] In some possible implementations, the bottom shell 1 has a bottom plate 11 and peripheral side plates 12 disposed around the edge of the bottom plate 11, the peripheral side plates 12 being perpendicular to the bottom plate 11. A connecting plate 212 is fitted to the bottom plate 11, forming a cutlery receiving groove 213 between the connecting plate 212 and the two side plates 211. Alternatively, the connecting plate 212 is located on one side of the opening of the cavity 101 of the bottom shell 1, with a gap between the connecting plate 212 and the bottom plate 11, and the rolled edge 31 of the stainless steel inner liner 3 is supported on the connecting plate 212. When there is only one extension 21, it is preferable to have the connecting plate 212 fitted to the bottom plate 11, forming the cutlery receiving groove 213 between the connecting plate 212 and the two side plates 211, thus facilitating the reception of cutlery. If there are multiple extensions 21, it is preferable to use extensions 21 with two different structures in combination, so that the connecting plate 212 is located at different heights, increasing the overall strength of the partition 2.

[0028] In some possible implementations, each extension 21 of the partition 2 includes a first directional extension 2101 and a second directional extension 2102. The first directional extension 2101 and the second directional extension 2102 are vertically connected. The first directional extension 2101 has the cutlery receiving groove 213. The first directional extension 2101 and the second directional extension 2102 divide the cavity 101 to form a plurality of partition grooves 1011.

[0029] This cross-shaped or near-cross-shaped extension design 21 further enriches the internal compartmentalization of the lunchbox. The first-direction extension 2101 and the second-direction extension 2102 are vertically connected, dividing the cavity 101 into multiple regular compartments 1011. Users can more flexibly allocate the use of each compartment 1011 according to the type and quantity of food. For example, staple food can be placed in a larger compartment 1011, while side dishes can be placed in the smaller compartments 1011, making food classification clearer and easier to access. Simultaneously, the cutlery storage slot 213 on the first-direction extension 2101 allows users to conveniently place cutlery during meals without needing to search for a place, improving dining convenience. Moreover, this vertically connected extension structure 21 enhances the overall stability of the divider 2, better supporting the weight of the stainless steel inner liner 3, ensuring the lunchbox will not deform or be damaged during use, and extending its lifespan.

[0030] In some possible implementations, the divider 2 includes at least one extension 21, which comprises a straight section 51 and a variable-diameter section 52. The variable-diameter section 52 is connected to the end of the straight section 51, and its width gradually increases in the direction from the straight section 51 to the variable-diameter section 52. The variable-diameter section 52 fits against the peripheral side plate 12 of the bottom shell 1. This design makes the connection between the extension 21 and the peripheral side plate 12 of the bottom shell 1 tighter and more stable. The gradually increasing width of the variable-diameter section 52 can better adapt to the shape of the peripheral side plate 12 of the bottom shell 1, increasing the contact area with the peripheral side plate 12, thereby improving the stability of the connection and preventing the divider 2 from shaking inside the bottom shell 1. At the same time, this structure also enhances the strength of the extension 21 itself, making it more reliable in supporting the stainless steel inner liner 3, less prone to deformation, and ensuring the normal use of the lunch box.

[0031] In some possible implementations, a limiting groove 7 is provided at at least part of the end of the variable diameter section 52. A baffle 121 is provided on the peripheral side plate 12. The baffle 121 is confined within the limiting groove 7. The cooperation between the limiting groove 7 and the baffle 121 further enhances the connection stability between the partition 2 and the bottom shell 1. When installing the partition 2, accurately embedding the baffle 121 into the limiting groove 7 effectively prevents the partition 2 from moving horizontally, ensuring that the partition 2 remains fixed within the bottom shell 1. This design not only improves the overall stability of the lunchbox structure, but also ensures that even if the lunchbox is subjected to a certain external impact or shaking during user use, the partition 2 will not easily dislodge from its original position, guaranteeing the stable placement of the stainless steel inner liner 3 and preventing food spillage. At the same time, this limiting structure is simple and easy to implement, reducing production costs and facilitating user installation and use.

[0032] In some possible embodiments, the partition 2 includes at least one extension 21, each extension 21 having a central straight surface 2111 and curved arc surfaces 2112 at both ends of the central straight surface 2111 on both sides along its thickness direction. The straight surface and the curved arc surfaces 2112 transition smoothly. When the stainless steel inner liner 3 is accommodated within the partition groove 1011, the outer wall of the stainless steel inner liner 3 conforms to the straight surface and the curved arc surfaces 2112. This design makes the fit between the extension 21 and the stainless steel inner liner 3 tighter and more perfect. The central straight surface 2111 provides stable support for the stainless steel inner liner 3, ensuring that the inner liner does not wobble within the partition groove 1011; while the curved arc surfaces 2112 at both ends better adapt to the circular outer wall shape of the stainless steel inner liner 3, increasing the contact area, dispersing pressure, and avoiding localized crush damage to the stainless steel inner liner 3. Meanwhile, the smooth transition between the flat surface and the curved surface 2112 makes the stainless steel inner liner 3 easier to insert and remove from the partition groove 1011 without any jamming, thus improving the user experience.

[0033] In some possible implementations, the outer surface of the base plate 11 of the bottom shell 1 is a completely flat surface. This design makes the lunchbox more stable when placed, preventing it from wobbling or tilting due to unevenness of the outer surface of the base plate 11. Whether placed on a tabletop or other flat surface, the stability of the lunchbox is guaranteed, making it convenient for users. At the same time, the completely flat surface design also facilitates cleaning the lunchbox. During washing, water can flow more smoothly over the outer surface of the base plate 11, preventing water accumulation or cleaning dead spots, and quickly cleaning stains from the base plate 11, maintaining the hygiene of the lunchbox. Moreover, this simple flat surface design conforms to modern aesthetics, making the lunchbox more beautiful and elegant in appearance.

[0034] In some possible implementations, the peripheral wall of the cutlery holder 213 is a closed ring. This closed ring design better protects the cutlery placed within the holder 213, preventing it from falling out during transport or use. Simultaneously, this design also prevents food residue or other debris from entering the holder 213, maintaining the cleanliness and hygiene of the cutlery. Furthermore, the closed ring structure is relatively simple, easy to manufacture and clean, reducing production and operating costs. Users can easily and quickly clean the cutlery holder 213 by simply rinsing it with water.

[0035] In some possible implementations, the divider 2 can be any one of a straight, cross, or T-shape. Different shapes of dividers 2 can meet diverse user needs. A straight divider 2 has a simple structure and is suitable for situations requiring fewer compartments 1011, dividing the lunchbox into two larger compartments 1011 for easier placement of larger food items. A cross-shaped divider 2 can divide the lunchbox into four compartments 1011, suitable for storing various types of food, achieving categorized food storage. A T-shaped divider 2 can divide the lunchbox into three compartments 1011 of different sizes according to user needs, offering greater flexibility. Users can choose the appropriate shape of divider 2 based on factors such as the number of diners, the types and quantities of food, making the use of the lunchbox more personalized and practical. Moreover, these different shaped dividers 2 can all adopt the aforementioned structural designs, ensuring stable support, good sealing performance, and ease of cleaning during use, providing users with a superior user experience.
