Description

Technical Field

[0001] The utility model belongs to the technical field of degradable tableware, in particular to a disposable fully biodegradable lunch box. Background Art

[0002] Due to the rapid development of today's era, industry and commerce have developed generally. In a situation where everything is about efficiency, fast food restaurants have become popular. These stores that aim to provide three meals a day quickly must use lunch boxes to hold food. The lunch boxes used earlier were mainly styrofoam lunch boxes. This type of lunch box not only does not meet environmental protection requirements, but also cannot hold food at higher temperatures. After use, this type of lunch box cannot decompose on its own, and will produce dioxin after burning, which will cause secondary environmental pollution. However, the overall market for lunch boxes is huge, but in order to avoid environmental pollution, degradable lunch boxes were born.

[0003] For example, patent application number CN202321804992.4 discloses a degradable lunch box with good sealing performance, which improves the problem that degradable lunch boxes are easy to deform and have poor sealing performance. It includes a box lid and a bottom box. The box lid and the bottom box are connected by a hinge plate. The top of the bottom box is fixedly connected with a sealing female buckle, the top of the box lid is provided with a sealing male buckle, the outer side of the box lid is provided with a sealing structure, and the bottom end of the bottom box is provided with a supporting structure. The sealing structure includes a limiting buckle, which is fixedly connected to the box lid. The present application can cooperate with the provided sealing female buckle, sealing male buckle, latch and limiting buckle structure. When using this lunch box, the latch and limiting buckle are closed, and the sealing female buckle and the sealing male buckle are connected to each other to form a relatively tight seal, thereby improving the sealing performance of the degradable lunch box. When the degradable lunch box is tilted 60°, it can still maintain a good seal, thereby preventing food from leaking from the gaps in the degradable lunch box.

[0004] In the prior art, the overall sealing and strength of the lunch box are effectively improved by changing its shape. However, there are still some deficiencies in the overall use process:

[0005] First, in the process of packing fast food boxes, in addition to the fast food boxes, they also need to be equipped with cutlery such as chopsticks, spoons and forks. These items are very easy to be skewed and shaken in the packing tape. When they are skewed or squeezed by foreign objects, the tips of the cutlery can easily puncture the lunch box or even the packaging bag, seriously affecting the delivery. In addition, during the transportation process, the soup in the fast food box often seeps onto the cutlery, forcing customers to frequently wipe the cutlery, seriously affecting the dining experience.

[0006] Secondly, when fast food boxes are transported to various restaurants, they often need to be stacked in large quantities. Some existing fast food boxes use a split design, that is, the box and the lid are transported separately, which is convenient for stacking. However, the lid or the box lacks a certain anti-slip structure, and the stacked items are often prone to tipping over and falling, causing the fast food boxes to be damaged, seriously affecting the use effect. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention provides a disposable fully biodegradable lunch box. The present invention provides a first storage slot, a second storage slot, and a convex block, allowing tableware to be placed above the lunch box lid. This reduces the risk of tableware puncturing the packaging bag and the fast food box, and prevents grease from sticking to the outside of the tableware, effectively improving the dining experience. Furthermore, combined with the lid edge ring and the second rough surface, the lids can be stacked to ensure good stability when transporting a large number of them, reducing the risk of them tipping over and breaking.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable fully biodegradable lunch box, comprising a lunch box lid and compartments, wherein a plurality of downwardly concave compartments are arranged on the end surface of the lunch box lid, a first storage groove for placing a spoon is arranged on the end surface of the lunch box lid between the plurality of compartments, a second storage groove for placing long objects is arranged on one side of the first storage groove, a plurality of anti-slip particles are arranged on the bottom end surface of the second storage groove, a plurality of convex blocks protruding outward are arranged on the upper end surface of the lunch box lid above the first storage groove and the second storage groove, a concave groove is arranged on the lower end surface of the lunch box lid in each of the convex blocks, when the plurality of lunch box lids are superimposed and abutted against each other, the convex blocks on the lower layer of the lunch box lid can be bent and abut against the outside of the concave groove of the upper layer, and a cover edge ring bent and deformed in the shape of a "J" is provided at the outer edge of the lunch box lid. The arrangement of the first storage slot and the second storage slot makes it easy to put tableware back in place, reducing the occurrence of damage to lunch boxes and packaging bags. The arrangement of the convex block and the concave slot ensures the overall stability of multiple lunch box covers when they are stacked for transportation.

[0009] According to the disposable fully biodegradable lunch box, the lunch box cover is entirely formed by pressing together fully bio-sheets based on thermoplastic starch.

[0010] According to the disposable fully biodegradable lunch box, the first storage slot and the second storage slot are both provided with an elliptical downwardly concave annular surface in the middle, which makes it easy to take out the placed tableware.

[0011] According to the disposable fully biodegradable lunch box, a corner piece is provided at one side corner of the cover ring. The provision of the corner piece enables the lunch box cover to be quickly removed without scalding when it is covered on the lunch box.

[0012] In the disposable fully biodegradable lunch box, the lid ring forms an annular groove with an open side. A plurality of second rough noodle strips are disposed on the sidewall of the annular groove near the opening, while a plurality of first rough noodle strips are disposed on the sidewall of the outer surface of the lid ring. The arrangement of the second rough noodle strips and the first rough noodle strips not only improves the sealing effect of the lunch box lid on the lunch box, but also enhances its transport stability.

[0013] According to the disposable fully biodegradable lunch box, a plurality of anti-skid ribs are provided on the bottom end surface of the second storage slot, so that the stability of the tableware when placed in the second storage slot is improved.

[0014] According to the disposable fully biodegradable lunch box, each of the compartments is connected to the recess of the lunch box cover to form an arc-shaped concave ring. The arrangement of the arc-shaped concave ring enables the lunch box cover to perform a secondary sealing process on the compartments inside the lunch box.

[0015] According to the above-mentioned disposable fully biodegradable lunch box, the first storage groove is in the shape of a spoon concave mold as a whole, and the compartments are in the shape of a rectangular concave mold as a whole.

[0016] In summary, compared with the prior art, the beneficial effects of this solution are:

[0017] (1) The present invention provides the first storage slot and the second storage slot as well as the convex block and the concave slot, so that the lunch box cover can not only collect and fix a variety of tableware during use, thereby reducing the possibility of the lunch box and the packaging bag being punctured, but also ensure stability during the process of large-scale stacking and transportation, reducing the possibility of tipping and falling, thereby effectively improving the overall applicability of the lunch box cover;

[0018] (2) The present invention provides a cover ring and an annular groove as well as a first rough surface and a second rough surface, so that when the lunch box cover is buckled on the upper end surface of the lunch box, the edge of the lunch box can be semi-wrapped and sealed. While improving the sealing effect, it can also improve the stability of multiple lunch box covers during stacking and transportation, so that the lunch box covers can be transported in large quantities and for a long time, which is convenient for the promotion of the lunch box cover as a whole;

[0019] (3) The utility model adds multiple concave and convex surfaces to the originally flat lunch box cover by means of compartments and arc-shaped concave rings, thereby improving the overall strength and performing secondary sealing on the compartments inside the lunch box, effectively reducing the flow and odor transfer of food in multiple compartments, and improving the dining experience.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Example 1:

[0032] Reference Attachment Figure 1 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Figure 9, a disposable fully biodegradable lunch box, including a lunch box lid 10, partitions 12. There are multiple downwardly recessed partitions 12 on the end face of the lunch box lid 10. A first storage groove 13 for placing spoons is provided on the end face of the lunch box lid 10 between the multiple partitions 12. A second storage groove 16 for placing long objects is provided on one side of the first storage groove 13. Multiple anti-slip particles 21 are provided on the inner bottom end face of the second storage groove 16. Multiple outwardly protruding convex blocks 14 are provided on the upper end face of the lunch box lid 10 above the first storage groove 13 and the second storage groove 16. A concave groove 24 is provided at the lower end face of the lunch box lid 10 inside each convex block 14. When multiple lunch box lids 10 are stacked and abutted against each other, the convex blocks 14 on the lower-layer lunch box lid 10 can be bent and abutted against the outside of the concave groove 24 on the upper layer. A lid edge ring 11 bent and deformed in a "Ji" shape is provided at the outer edge of the lunch box lid 10.

[0033] Specifically, the lunch box body is a prior art. The overall shape and size of this solution are not described in detail compared with the legend. The overall size of the lunch box lid 10 and the lid edge ring 11 is set according to the specifications of the actual sizes of various lunch boxes. The lid edge ring 11 is integrally formed by die pressing outside the lunch box lid 10 and has an open shape at the lower end. The user can buckle the lunch box lid 10 on the lunch box, and the lid edge ring 11 will be pressed semi-wrapped on the edge of the lunch box, so as to seal the lunch box. In this solution, the sizes and shapes of the multiple partitions 12 on the end face of the lunch box lid 10 are set according to the specific compartments inside the lunch box. This solution does not make excessive settings. The setting of the partitions 12 makes the overall lunch box lid have multiple concave and convex bending surfaces compared with the traditional flat lunch box lid, forming multiple positions for bearing deformation pressure. The overall strength and hardness are effectively improved compared with the flat lunch box.

[0034] The first storage groove 13 provided on the end face of the lunch box lid 10 between the multiple partitions 12 can place spoons, and the second storage groove 16 can be used to place long objects such as chopsticks or straws. The setting of the first storage groove 13 and the second storage groove 16 enables catering personnel not to place dining tools in the packing bag when packing, reducing the situation that chopsticks or pointed objects pierce the fast food box or the bag, and can also avoid the situation that the liquid in the lunch box flows and adheres to the cutlery and its packaging, effectively improving the dining experience. In this solution, since the second storage groove 16 is for placing long objects, the bottom is relatively flat. Multiple upwardly protruding anti-slip particles 21 provided at the bottom of the second storage groove 16 can effectively increase the contact friction with the objects, so that long objects such as chopsticks and straws will not shake randomly when placed inside the second storage groove 16.

[0035] A plurality of convex blocks 14 are provided on the lunch box cover 10 on both sides above the first storage slot 13 and the second storage slot 16, and the whole protrudes above the first storage slot 13 and the second storage slot 16, so that when a spoon or a long object is placed inside the first storage slot 13 and the second storage slot 16, in addition to the bottom and the two side walls being limited, the top can also be limited to a certain extent, so that the spoon and the long object will not fall outward. When the convex blocks 14 are formed, concave grooves 24 corresponding to each other and recessed inwardly are provided on the lower end surface of the lunch box cover 10 in the convex blocks 14. When the lunch box cover 10 needs to be transported in large quantities, multiple lunch box covers 10 need to be spaced apart. To be stacked on each other for transportation, during the stacking process, in addition to the multiple concave and convex surfaces formed on the surface of the lunch box cover 10 cooperating with each other, when the lunch box cover 10 on the upper layer is placed on the lunch box cover 10 on the lower layer, the multiple convex blocks 14 on the lower layer will bend and deform to a certain extent due to contact with foreign objects. The bent and deformed convex blocks 14 will be pressed on the outside of the concave grooves 24 on the upper layer, producing an effect similar to meshing and clamping, thereby effectively improving the overall stability of the multiple lunch box covers 10 when stacked and moved. In this solution, the convex blocks 14 will not be embedded in the concave grooves 24 due to their shape and size, and the clamping and abutment are completed based on the bending pressure generated by elastic deformation.

[0036] For further information, see the attached Figure 1 The lunch box cover 10 is formed by pressing together a full-biological sheet based on thermoplastic starch.

[0037] Specifically, the all-biological sheet material based on thermoplastic starch has good heat resistance and aesthetics, so that the lunch box cover 10 can be used in a variety of complex storage environments, improving the applicability. In this solution, the specific sheet material is the existing technology and will not be elaborated in detail in this solution.

[0038] For further information, see the attached Figure 1 and attached Figure 3 The first storage tank 13 and the second storage tank 16 are both provided with an annular concave surface 15 that is elliptical and concave downward in the middle.

[0039] Specifically, the first storage slot 13 and the second storage slot 16 are both arranged according to the shape of the tableware. Once the tableware is placed inside the first storage slot 13 and the second storage slot 16, it is difficult to remove it. Therefore, an elliptical downwardly concave annular concave surface 15 is provided on both sides of the middle of the first storage slot 13 and the second storage slot 16, so that diners can extend their fingers to the outside of the tableware, making it easier to take the tableware.

[0040] For further information, see the attached Figure 1 , and attached Figure 2 A corner piece 18 is provided at one side corner of the cover edge ring 11.

[0041] Specifically, when the lunch box cover 10 is covered on the lunch box through the cover edge ring 11, the cover edge ring 11 will cover the edge of the lunch box in a semi-wrapped state to ensure sealing, but the lunch box cover 10 is not easy to take off. At this time, the diners can pull the corner piece 18 upward to pull the lunch box cover 10 upward, so that the lunch box cover 10 can be removed. In this solution, the outward extending corner piece 18 can also prevent heat from being transferred to the upper side, reducing the occurrence of burns when taking the lunch box cover 10. The surface of the corner piece 18 is roughened to improve the gripping effect.

[0042] For further information, see the attached Figure 6 An annular groove 19 with an opening on one side is formed in the cover ring 11, and a plurality of second rough noodles 23 are provided on the side wall near the opening in the annular groove 19, and a plurality of first rough noodles 22 are provided on the side wall of the outer surface of the cover ring 11.

[0043] Specifically, the lid edge ring 11 is curved as a whole, forming an annular groove 19 with an open side. When in use, the lid edge ring 11 contacts the edge of the lunch box through the wall of the annular groove 19 to achieve a sealing effect. The multiple second rough noodles 23 provided on the inner wall of the annular groove 19 can effectively increase the contact friction and ensure the sealing effect.

[0044] During the transportation of multiple lunch box lids 10, the upper and lower lid edge rings 11 will also be buckled with each other through the annular groove 19. During this process, the multiple inner walls of the annular groove 19 can contact the multiple first rough noodles 22 on the outside of the lid edge ring 11, so that the contact friction between the lid edge rings 11 on the outside of the upper and lower lunch box lids 10 is improved, further ensuring the stability during transportation and reducing the occurrence of shaking and skewing.

[0045] For further information, see the attached Figure 6 The first storage slot 13 is in the shape of a spoon concave mold as a whole, and the compartment 12 is in the shape of a rectangular concave mold as a whole.

[0046] Specifically, the first storage slot 13, including the edge and bottom shape, are arranged in the shape of a spoon mold, so that the spoon can be effectively placed inside the first storage slot 13, thereby improving stability during placement; the rectangular mold-shaped arrangement of the partition 12 allows the partition 12 to store a variety of long objects such as chopsticks or straws of different sizes, thereby improving storage capacity.

[0047] Example 2:

[0048] Reference Attachment Figure 6 , a disposable fully biodegradable lunch box, a plurality of anti-slip ribs 17 are provided on the bottom end surface of the second storage tank 16.

[0049] As a further embodiment, arranging a plurality of anti-skid ribs 17 when there are already anti-skid particles 21 at the bottom of the second storage tank 16 can effectively reduce the occurrence of slipping and shaking of long objects, and further ensure that the materials inside the second storage tank 16 will not fall out at will.

[0050] Example 3:

[0051] Reference Attachment Figure 2 and attached Figure 7 , a disposable fully biodegradable lunch box, each compartment 12 is connected to the recess of the lunch box cover 10 to form an arc-shaped concave ring 20.

[0052] As a further embodiment, the partition 12 is set to be recessed downward according to the number and size of the grids of the lunch box. During the recessing process, an arc-shaped concave ring 20 will be formed. This arc-shaped concave ring 20 is coordinated with the number, size and shape of the grids inside the lunch box. The bottom end face of the arc-shaped concave ring 20 can abut against the upper end faces of multiple grids of the lunch box, thereby performing secondary partitioning on the multiple grids inside the lunch box, thereby preventing the food in the multiple grids from flowing into each other and mixing flavors.
