Abstract
Description
[Technical Field] This utility model belongs to the field of lunch box technology, and in particular relates to a lunch box with partitioned built-in tableware. [Background Technology] Portable lunchboxes are widely used by office workers, students, and people engaged in outdoor activities to carry meals in daily life. However, existing lunchboxes generally suffer from limited functionality and fixed internal structures, typically only having a compartment for holding food. Users often need to carry additional utensils such as chopsticks, spoons, or forks, which not only increases the burden of carrying them but also easily leads to lost utensils or hygiene hazards.
[0001] To address the aforementioned issues, existing technologies have attempted to integrate cutlery storage structures into lunch boxes. For example, Chinese invention patent application CN108937046A discloses a lunch box with a fork, which features a slot on the outside of the lid to hold the fork. While this allows the cutlery to be carried with the box, the cutlery is exposed, making it susceptible to contamination, affecting the seal, and compromising the overall appearance. Chinese utility model patent CN212814906U discloses a lunch box that can hold cutlery, with a toothed cavity on the top surface of the lid for holding disposable cutlery. Friction textures and locking protrusions prevent slippage, improving stability. However, the cutlery is still placed on the outer surface of the lid, making it difficult to avoid the risk of contamination during transportation. Furthermore, it is only suitable for disposable cutlery sets, limiting its versatility. Chinese invention patent application CN106666977A discloses a portable lunch box with an independent cutlery tray between the box body and the lid. The cutlery can be detached and combined to achieve multi-functional use. However, the cutlery tray requires additional height space inside the box body, which not only increases the complexity of the overall structure but also reduces the food holding volume, affecting portability. [Utility Model Content] The purpose of this invention is to provide a lunchbox with partitioned built-in tableware to solve the problems of easy loss and contamination of external tableware and large space occupation of built-in tableware in the prior art.
[0002] This utility model is achieved by the following technical solution: A lunch box with partitioned built-in tableware includes a box body and a box lid. The box body has an inner box for partitioning, which is divided into a storage area for placing tableware and a serving area for holding food.
[0003] As described above, the lunch box with compartmentalized built-in tableware has a strip-shaped storage area that is arranged along the diagonal direction of the inner box.
[0004] As described above, the lunchbox with built-in tableware in partitioned sections includes at least a first serving area and a second serving area for holding food.
[0005] As described above, the lunch box with compartmentalized built-in tableware has a first connecting flange on the outer side wall of the inner box that connects to the box body, and an exhaust groove for venting.
[0006] As described above, in a lunchbox with compartmentalized built-in cutlery, the venting groove extends from the first connecting flange toward the bottom of the inner box and forms an venting channel with the inner sidewall of the box for venting.
[0007] As described above, the lunch box with compartmentalized built-in tableware has a receiving cavity inside the box for accommodating the inner box, and a limiting groove for fixing the first connecting flange.
[0008] As described above, the lunch box with compartmentalized built-in tableware has a second connecting flange on the outer side wall of the box body that connects to the lid.
[0009] As described above, the lunch box with compartmentalized built-in tableware has a lid with a third connecting flange and a fourth connecting flange for connection, and a fixing groove is formed between the third connecting flange and the fourth connecting flange for connection with the second connecting flange.
[0010] As described above, the lunch box with compartmentalized built-in tableware has a fixing protrusion on the side of the fourth connecting flange facing the fixing groove for enhanced fixing.
[0011] As described above, the lunch box with compartmentalized built-in tableware has a lid with a vent for exhaust and a grip for opening the lid.
[0012] This invention proposes a lunchbox with partitioned internal cutlery. By setting an inner box inside the box, the internal space is divided into independent storage and serving areas, achieving physical isolation between cutlery and food. This effectively prevents cross-contamination caused by contact between cutlery and food during transport, significantly improving hygiene. Secondly, the serving area of the inner box can be divided into multiple zones to facilitate the holding of different dishes. The storage area adopts a strip structure and is set along the diagonal direction of the inner box, making full use of corner space and maximizing the length of cutlery that can be accommodated within the limited box size. This balances functional layout and space efficiency, solving the problems of easy loss and contamination of external cutlery and the large space occupied by the internal cutlery structure in existing technologies.

Detailed Implementation Methods
[0013] This utility model divides the internal space into an independent storage area and a serving area by setting an inner box inside the box, thereby achieving physical isolation between tableware and food, effectively preventing cross-contamination caused by tableware coming into contact with food during transportation, and significantly improving the hygiene of use.
[0014] Furthermore, the storage area 31 is strip-shaped and is arranged along the diagonal direction of the inner box 3.
[0015] This invention significantly increases the effective length of the container for tableware by arranging the strip-shaped storage area along a diagonal direction, making full use of the maximum diagonal dimension inside the inner box. Simultaneously, this diagonal layout naturally divides the remaining space inside the box into two relatively independent areas. Depending on different usage needs, one or more serving areas can be set on one side, or one or more serving areas can be set on each side, achieving flexible food partitioning and effectively reducing cross-contamination of odors and spills, thus improving overall convenience and hygiene.
[0016] Furthermore, the serving area 32 includes at least a first serving area 321 and a second serving area 322 for serving food.
[0017] Furthermore, the storage area 31 is located between the first serving area 321 and the second serving area 322, and the first serving area 321 and the second serving area 322 are arranged in a 180° rotational symmetry about the center of the storage area 31.
[0018] In this embodiment, the first and second serving areas have the same shape, both enclosed by the side walls of the inner box and the edge of the storage area, with an overall outline roughly triangular or trapezoidal. This design achieves a balanced distribution of space within the box, effectively avoiding wasted space in corners or edges; especially in square or rectangular inner boxes, it allows for more efficient use of the side areas, maximizing effective volume. Furthermore, the two independent serving areas allow users to separately hold staple foods, main dishes, side dishes, or hot and cold dishes, effectively preventing flavors from mixing and broth from contaminating, thus meeting the demands of modern healthy eating for individual servings and dietary diversity.
[0019] Furthermore, the outer side wall of the inner box 3 is provided with a first connecting flange 33 that connects to the box body 1, and an exhaust groove 34 for exhausting.
[0020] Furthermore, the exhaust groove 34 extends from the first connecting flange 33 toward the bottom of the inner box 3 and forms an exhaust channel for exhaust with the inner sidewall of the box body 1.
[0021] This utility model's venting groove extends downwards from the first connecting flange, utilizing the minute gap between the outer wall of the inner box and the inner wall of the box to form a continuous and directional venting channel. This channel extends to the bottom area of the inner box and communicates with the receiving cavity inside the box. During heating or cooling, the air or water vapor inside the lunchbox experiences pressure changes due to thermal expansion and contraction. This venting channel can promptly expel excess gas or introduce external air, effectively balancing the internal and external air pressure. This avoids problems such as the lid bulging or even popping open, the inner box deforming under pressure, floating, or being difficult to remove caused by a sudden increase in air pressure or negative pressure adsorption.
[0022] Furthermore, the box body 1 is provided with a receiving cavity 11 for accommodating the inner box 3, and a limiting groove 12 for fixing the first connecting flange 33.
[0023] When in use, this utility model achieves a detachable connection between the inner box and the box body by engaging the first connecting flange with the limiting groove, which facilitates installation and removal, and is beneficial for cleaning and maintenance.
[0024] Furthermore, the outer wall of the box body 1 is provided with a second connecting flange 13 that connects to the box cover 2.
[0025] Furthermore, the cover 2 is provided with a third connecting flange 21 and a fourth connecting flange 22 for connection, and a fixing groove 23 for connection with the second connecting flange 13 is formed between the third connecting flange 21 and the fourth connecting flange 22.
[0026] Furthermore, the fourth connecting flange 22 is provided with a fixing protrusion 221 for strengthening the fixing on the side facing the fixing groove 23.
[0027] When in use, this utility model achieves a detachable connection between the box body and the box cover by engaging the second connecting flange with the fixing groove. When sealing or opening, the user can complete the assembly or disassembly by pressing down or lifting the box cover. The operation is simple and convenient for sealing, opening and closing, and cleaning and maintenance.
[0028] Furthermore, the lid 2 is provided with a vent 24 for venting and two grips 25 for opening the lid.
