[0002] A vacuum bag, also known as a skin-friendly moisture-proof bag, an aluminum foil bag, or an aluminum-plastic composite bag, is generally made of PET / AL / CPE or PET / NY / AL / CPE, where PET has good printing effect, NY has low oxygen permeability, AL has strong barrier property and is light-impermeable, CPE is the inner layer of the package, and the glue is water-soluble glue. This product has good anti-static, oxygen isolation, shielding, moisture-proof, light-shielding functions and excellent heat-sealing property.
[0003] When the vacuum bag film is in use, due to its very thin thickness, when stored at low temperature for a long time, the low-temperature environment will cause the internal structure to harden, and long-term placement will cause damage from the inside out, reducing its freshness preservation effect, thereby reducing the practicality of the vacuum bag film. Therefore, for the improvement of the existing vacuum bag, it is particularly important to design a new type of embossed vacuum bag to solve the above technical defects and improve the overall practicality of the vacuum bag.

At the same time, through the design of the buffer layer, if the vacuum bag body is placed in a low-temperature or high-temperature environment, its elastic sheet cooperates with the internal elastic strip, so that when it expands and contracts due to thermal expansion and contraction in the low-temperature or high-temperature environment, it has a certain stretching buffer property, and its internal part is not easily cracked and finally causes damage to the bag film due to long-term accumulation. At the same time, the elastic sheet, supported by the elastic strip, plays a role in shaping the vacuum bag body, so as to solve the problems put forward in the above background technique.

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment:
[0024] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:
[0025] A embossed vacuum bag, including a vacuum bag main body 1, the vacuum bag main body 1 is composed of a buffer layer 2 and a heat insulation layer 3, the buffer layer 2 is located outside the heat insulation layer 3, a connecting belt 4 is arranged outside the vacuum bag main body 1, and a connecting ring 5 is arranged inside the connecting belt 4;
[0026] The heat insulation layer 3 is used to increase the heat insulation effect of the vacuum bag main body 1, and the heat insulation layer 3 is composed of a connecting layer 6, a cavity 7 and an airbag 8. The connecting layer 6 is located outside the buffer layer 2, the cavity 7 is opened inside the connecting layer 6, and multiple groups of airbags 8 are all located outside the connecting layer 6;
[0027] The buffer layer 2 is used to increase the buffering performance of the vacuum bag main body 1.
[0028] Furthermore, multiple groups of airbags 8 are evenly distributed outside the connecting layer 6, and heat insulation materials are arranged at both ends inside the cavity 7 and inside the connecting layer 6. When the vacuum bag main body 1 is in use, through the cooperation of the airbag 8 with the cavity 7 and the heat insulation materials inside it, when in use, it is placed in environments with different temperatures, so that the internal temperature of the vacuum bag main body 1 is not easily dissipated, and the fresh vegetables in it are not overly affected by the drastic changes in the external environmental temperature and the preservation quality.
[0029] Wherein, a connecting pipe 9 is provided outside the airbag 8 and on the outside of the connecting layer 6. Both ends of the connecting pipe 9 are respectively connected to two groups of airbags 8. Multiple groups of airbags 8 are interconnected through multiple groups of connecting pipes 9. When connecting the connecting pipe 9 to the airbag 8 and using the vacuum bag body 1, the airbag 8 and the buffer layer 2 cooperate to increase the buffering performance of the vacuum bag body 1.
[0030] Secondly, the buffer layer 2 is composed of elastic sheets 10 and elastic strips 11. Multiple groups of elastic sheets 10 are all located outside the connecting layer 6, and the elastic strips 11 are located inside the elastic sheets 10. When using the vacuum bag body 1, the buffer layer 2 has a certain stretching and buffering performance, so that cracks are not likely to appear inside it, and long-term accumulation will not eventually lead to damage to the bag film.
[0031] Furthermore, the elastic sheet 10 is designed in an arc structure, and multiple groups of elastic sheets 10 are interconnected to form a wavy structure. The elastic strip 11 is designed in a circular structure, and the elastic strip 11 is connected to the connecting layer 6 through the elastic sheet 10. If the vacuum bag body 1 is placed in a low-temperature or high-temperature environment, the elastic sheet 10 and the internal elastic strip 11 cooperate to make it have a certain stretching and buffering performance when thermal expansion and contraction occur in the low-temperature or high-temperature environment, so that cracks are not likely to appear inside it, and long-term accumulation will not eventually lead to damage to the bag film. At the same time, the elastic sheet 10 is supported by the elastic strip 11 to shape the vacuum bag body 1, thereby improving the practicality of the device.
[0032] Furthermore, an elastic block 12 is provided inside the connecting ring 5. The elastic block 12 is designed in a circular structure, and a connecting groove 13 is opened inside the elastic block 12. When it is necessary to hang the vacuum bag body 1, the connecting ring 5 is connected to the hook. The elastic block 12 contacts the hook through the connecting groove 13 inside it. Through its own elasticity, it can fit the surface of the hook to prevent the vacuum bag body 1 from shaking and falling off the outside of the hook.
[0033] In this embodiment, the implementation scenario is specifically as follows: when the vacuum bag body 1 is in use, the airbag 8 cooperates with the cavity 7 and the heat-insulating material inside it. When in use, it is placed in environments with different temperatures, so that the internal temperature of the vacuum bag body 1 is not easily dissipated, and the fresh vegetables inside are not overly affected by the drastic changes in the external environmental temperature, thus ensuring the preservation quality. If the vacuum bag body 1 is placed in a low-temperature or high-temperature environment, the elastic sheet 10 cooperates with the internal elastic strip 11, enabling it to have a certain stretching buffer when undergoing thermal expansion and contraction in a low-temperature or high-temperature environment, preventing cracks from occurring inside and eventually causing damage to the bag film due to long-term accumulation. At the same time, the elastic sheet 10, supported by the elastic strip 11, plays a role in shaping the vacuum bag body 1. When it is necessary to hang the vacuum bag body 1, the connecting ring 5 is connected to the hook. The elastic block 12 contacts the hook through the connecting groove 13 inside it. Due to its own elasticity, it can fit the surface of the hook, preventing the vacuum bag body 1 from shaking and falling off the outside of the hook. Compared with the existing vacuum bags, the overall practicality of the vacuum bag can be improved through the design of the present utility model.
[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
