Description

Technical Field

[0001] This utility model relates to the field of meal packs, specifically an insulated meal pack. Background Technology

[0002] In daily life and work, insulated lunch bags have become a common tool for carrying meals. Existing insulated lunch bags typically only offer basic insulation and storage functions, but they have many shortcomings in actual use. Because users place items of varying sizes inside, and the lack of an effective internal securing structure, items easily slide around inside the bag. When carrying liquids such as soup or drinks, the bag's movement during walking or moving can easily cause spills, soiling the inside and making cleaning difficult. Furthermore, if the bag is subjected to impacts or movement, the contents may flip over, further damaging items or spilling food, causing significant inconvenience and reducing the user experience. Therefore, there is an urgent need to design an insulated lunch bag that can effectively secure the contents and prevent them from sliding or flipping. Utility Model Content

[0003] This invention provides an insulated lunch bag to address the problems of existing technologies.

[0004] The objective of this utility model can be achieved through the following technical solution: An insulated lunch bag includes: a bag body, a handle, a horizontal limiting elastic band, and a vertical limiting elastic band. The handle is located on the upper sides of both sides of the bag body. A zipper is provided on the top of the bag body. A buckle 1 and a limiting cap 1 are sequentially fixed upward on the right side inside the bag body. A buckle 2 and a limiting cap 2 are sequentially fixed upward on the rear side inside the bag body. One side of the horizontal limiting elastic band is fixed to the left side inside the bag body. The horizontal limiting elastic band has a positioning hole 1 spaced apart. After the horizontal limiting elastic band passes through the buckle 1, the limiting cap 1 snaps through the positioning hole 1. One side of the vertical limiting elastic band is fixed to the front side inside the bag body. The vertical limiting elastic band has a positioning hole 2 spaced apart. After the vertical limiting elastic band passes through the buckle 2, the limiting cap 2 snaps through the positioning hole 2.

[0005] In a further improvement, the bag body comprises, in turn, an outer layer, an insulation layer, and an inner layer.

[0006] In a further improvement, the outer layer is made of Oxford cloth, the insulation layer is made of pearl cotton, and the inner layer is made of polyethylene-vinyl acetate copolymer.

[0007] In a further improvement, both the first and second buckles are provided with L-shaped channels. The horizontal limiting elastic band passes through the L-shaped channel of the first buckle to the top, and the vertical limiting elastic band passes through the L-shaped channel of the second buckle to the top.

[0008] In a further improvement, the handle is fixedly attached to the bag body by stitching.

[0009] Compared with existing technologies, the beneficial effects of this insulated lunch bag are as follows:

[0010] By setting horizontal and vertical elastic bands for limiting movement, along with buckles, limiting caps, and spaced positioning holes, a two-way adjustable limiting structure is constructed. This replaces the limitation of traditional dinner bags lacking an effective fixing structure, allowing for flexible adjustment of the pre-tightening degree according to the size of the items, achieving precise fixing. It also makes the horizontal and vertical elastic bands more rationally distributed within the bag, making installation and adjustment smoother. At the same time, it enhances the structural strength at the connection between the buckle and the elastic band, reducing the risk of damage due to stress and improving the overall structural stability of the dinner bag.

[0018] The following describes the embodiments and appendices. Figs. 1-5 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] An insulated lunch bag includes: a bag body 1, a handle 2, a horizontal limiting elastic band 3, and a vertical limiting elastic band 4. The handle 2 is located on the upper sides of both sides of the bag body 1 for easy carrying. The top of the bag body 1 has a zipper 18. As a common opening and closing structure, the zipper is easy to operate and can tightly close the bag to prevent internal heat loss and dust entry. The right side inside the bag body 1 is fixed with a first buckle 11 and a limiting cap 12, and the rear side inside the bag body 1 is fixed with a second buckle 11. 3 and limiting cap 14, the horizontal limiting elastic band 3 is fixed on one side of the inside left side of the bag body 1, the horizontal limiting elastic band 3 is provided with positioning holes 31 at intervals, the horizontal limiting elastic band 3 passes through buckle 11 and then the limiting cap 12 is engaged through the positioning hole 31, the vertical limiting elastic band 4 is fixed on one side of the inside front side of the bag body 1, the vertical limiting elastic band 4 is provided with positioning holes 41 at intervals, the vertical limiting elastic band 4 passes through buckle 13 and then the limiting cap 14 is engaged through the positioning hole 41.

[0021] like Figs. 1-5 As shown, the working principle of this utility model is as follows: the horizontal limiting elastic band 3 and the vertical limiting elastic band 4 utilize their elastic properties to apply a certain binding force to the items placed inside the bag. When placing items of different sizes, the user can pass the limiting elastic bands through the buckles and adjust them to the appropriate positioning holes according to the size of the items. The limiting caps are then used to lock the position of the limiting elastic bands in place, thereby limiting the items in both the horizontal and vertical directions. This two-way limiting design is like building a stable frame for the items, firmly fixing them inside the bag and effectively preventing them from sliding or flipping due to shaking. Even if the items contain liquid, it can prevent the liquid from spilling due to shaking.

[0022] The combination of positioning holes 31 and limiting caps 12 spaced apart on the horizontal limiting elastic band 3 enables adjustable pre-tensioning. When placing smaller items, the user can pass the horizontal limiting elastic band 3 through the buckle 11 and select the positioning hole 31 closest to the fixed end. At this time, the limiting cap 12 engages with the positioning hole, and the elastic band is in a relatively taut state, applying a strong binding force to the item and firmly fixing the small item to prevent it from sliding freely inside the bag. When placing larger items, the positioning hole 31 furthest from the fixed end is selected. At this time, the elastic band stretches less, forming a relatively loose binding, which can firmly restrict the displacement of large items without causing damage to the items due to excessive compression. The positioning hole 41 and limiting cap 14 on the vertical limiting elastic band 4 follow the same principle. With this flexible adjustment method, the horizontal and vertical limiting elastic bands work together to achieve precise and appropriate pre-tightening and fixation according to their size characteristics by adjusting the snap-fit ​​position of the positioning hole and the limiting cap. This ensures that items of different sizes remain stable inside the lunch bag at all times. Even under violent shaking or bumping, it can effectively prevent items from sliding or turning over, completely solving the problem of liquid spillage or item damage caused by shaking, and greatly improving the safety and reliability of insulated lunch bags.

[0023] As a further preferred embodiment, the bag body 1 includes, inwardly, an outer layer 15, an insulation layer 16, and an inner layer 17. The outer layer 15 is made of Oxford cloth, which is dense, wear-resistant, waterproof, and dustproof, effectively resisting external friction, scratches, and rain erosion, thus extending the service life of the bag. The insulation layer 16 is made of pearl cotton, a new type of environmentally friendly material with an independent bubble structure. Its interior is filled with a large number of tiny closed bubbles, which effectively prevent air convection and reduce heat conduction and loss, thereby achieving a good insulation effect. The inner layer is made of polyethylene-vinyl acetate copolymer, which is non-toxic, odorless, and chemically stable, and will not react chemically with food, ensuring food safety and hygiene.

[0024] As a further preferred embodiment, both the first buckle 11 and the second buckle 13 are provided with L-shaped channels inside. The horizontal limiting elastic band 3 passes through the L-shaped channel of the first buckle 11 to the top, and the vertical limiting elastic band 4 passes through the L-shaped channel of the second buckle 13 to the top. The design of the L-shaped channel can, on the one hand, change the direction of the limiting elastic band, so that the elastic band is reasonably distributed in the bag and makes full use of space to limit the items; on the other hand, the L-shaped structure can provide a certain guiding and supporting effect for the limiting elastic band.

[0025] As a further preferred embodiment, the handle 2 is fixedly connected to the bag body 1 by sewing.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
