Abstract
Description
Technical Field
[0001] This utility model relates to the field of lunch box technology, specifically to a lunch box with a stable structure. Background Technology
[0002] Lunch boxes are a common household item used in daily life. They are used to carry prepared meals so that people can eat at work or outside. Disposable lunch boxes are one type of lunch box, and their use is increasing due to the fast pace of life. However, traditional disposable lunch boxes are generally made of plastic with smooth sidewalls, resulting in low strength. They are prone to slipping from the hand and deforming at the outer edge, causing inconvenience and a poor user experience. Therefore, to avoid these shortcomings, it is necessary to improve the existing technology. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a convenient and structurally stable lunchbox.
[0004] This utility model is achieved through the following technical solution:
[0005] A sturdy lunchbox includes a lunchbox body, the peripheral wall of the lunchbox body is provided with a number of reinforcing ribs, the reinforcing ribs are provided from bottom to top, the inner side of the top of the lunchbox body is provided with a number of pressure grooves, and the outer side of the top of the lunchbox body is provided with an outer eave.
[0006] Furthermore, the outer edge of the outer eaves is provided with a downwardly sloping folded edge.
[0007] Furthermore, the reinforcing ribs are arranged to gradually decrease in size from bottom to top.
[0008] Furthermore, the inner side of the bottom of the lunchbox body is provided with an upwardly protruding boss.
[0009] Furthermore, the outer side of the bottom of the lunchbox body is provided with a downward-protruding support protrusion.
[0010] Furthermore, the outer side of the bottom of the lunchbox body is provided with several bevels.
[0011] Furthermore, the wall thickness of the main body of the lunchbox is 0.3mm to 2mm.
[0012] Furthermore, the main body of the lunchbox gradually increases in size from bottom to top.
[0013] Furthermore, the main body of the lunchbox is a square lunchbox body, and the bottom of the corner of the lunchbox body is provided with a chamfer.
[0014] Furthermore, the main body of the lunchbox is a plastic lunchbox body.
[0015] Compared to existing technologies, this utility model features several reinforcing ribs on the periphery of the lunchbox body, extending from bottom to top. Several pressure grooves are provided on the inner side of the top of the lunchbox body, and an outer eave is provided on the outer side of the top of the lunchbox body. The reinforcing ribs, pressure grooves, and outer eaves make the lunchbox structure stable. The side walls of the lunchbox are concave and convex, resulting in high strength. The lunchbox will not slip from the hand during use, and the outer wall of the lunchbox is not easily deformed when held. It is convenient to use and provides a good user experience.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4The present invention discloses a structurally stable lunchbox, comprising a lunchbox body 1. The lunchbox body 1 has several reinforcing ribs 2 on its peripheral walls, extending from bottom to top. The inner side of the top of the lunchbox body 1 has several pressure grooves 3, and the outer side of the top of the lunchbox body 1 has an outer rim 4. The reinforcing ribs 2, pressure grooves 3, and outer rim 4 ensure the lunchbox's structural stability. The concave-convex sidewalls of the lunchbox provide high strength, preventing the lunchbox from slipping from the hand during use and minimizing deformation at the outer wall when held. This design makes the lunchbox convenient to use and provides a good user experience.
[0024] The outer edge 4 has a downward-sloping folded edge 5 on its outer side, which improves the structural strength of the outer edge 4. When using it, the lunch box can be lifted by holding the outer edge 4, and the lunch box lid can be easily placed on the outer edge 4, making it convenient to use.
[0025] The reinforcing rib 2 is designed to gradually decrease in size from bottom to top, which saves materials and balances the stress on the lunchbox.
[0026] The inner side of the bottom of the lunchbox body 1 is provided with an upward protrusion 6 to improve the structural strength of the bottom of the lunchbox.
[0027] The outer side of the bottom of the lunchbox body 1 is provided with a downward-protruding support protrusion 7, which improves the structural strength of the bottom of the lunchbox and makes the lunchbox more stable when placed.
[0028] The outer side of the bottom of the lunchbox body 1 is provided with several beveled angles 8 to improve the structural strength of the bottom of the lunchbox.
[0029] In practice, the wall thickness of the main body 1 of the lunchbox is 0.3mm to 2mm.
[0030] The main body of the lunchbox 1 gradually increases in size from bottom to top, making it easy to unmold the lunchbox and hold food.
[0031] As one specific implementation, the lunchbox body 1 is a square lunchbox body, and the bottom of the corner of the lunchbox body 1 is provided with a chamfer 9 to improve the structural strength of the bottom of the lunchbox.
[0032] In specific implementation, the main body of the lunch box 1 is a plastic lunch box body, which has low production cost. As a specific implementation method, the main body of the lunch box 1 is a PP plastic lunch box body, which is easy to mold and has good toughness.
[0033] The above description is only a preferred embodiment of the present utility model and is 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.
