Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a turnover bag with a wear-resistant bottom. Background Art

[0002] Turnover bags are a type of container specifically used for material turnover. They usually refer to bags used to transport and store various materials. They can be reused many times, so they are called "turnover" bags. These bags are widely used in the storage and transportation of industrial raw materials, products, parts, etc., and play an important role in logistics management.

[0003] The bottom of existing turnover bags is prone to wear and tear due to direct contact with the ground and bearing the weight of the goods. Especially when loading heavy items or moving on rough surfaces, this wear greatly increases the possibility of damage to the bottom of the turnover bag. Therefore, the utility model aims to provide a turnover bag with a more wear-resistant bottom. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: See Figures 1 to 3 According to an embodiment of the present invention, a technical solution is provided: a bottom wear-resistant turnover bag, comprising a bag body 1; an abutting portion 2, which is arranged at the bottom of the bag body 1, and defines an inner cavity 3 in the abutting portion 2, and the inner cavity 3 can change its effective volume by the amount of gas placed therein, and a one-way gas valve 4 connected to the inner cavity 3 is provided on the abutting portion 2 to limit the gas in the inner cavity 3 from being discharged outside the inner cavity 3; an anti-scratch portion 5, which is arranged at the bottom of the abutting portion 2 to prevent external media from scratching the bottom of the abutting portion 2.

[0025] With the bottom wear-resistant turnover bag of the above-mentioned structure, before using the bag body 1 to load goods, the user first injects gas into the inner cavity 3 through the one-way gas valve 4 to expand the volume of the inner cavity 3, thereby increasing the supporting force of the bottom of the abutment portion 2. As the amount of gas in the inner cavity 3 increases, the bottom of the abutment portion 2 will become stronger, which can effectively prevent the bag body 1 from being deformed or damaged due to pressure on the bottom when loading heavy objects. During the transportation of the bag body 1, the anti-scratch portion 5 can prevent external media, such as sharp objects, rough surfaces, etc., from directly contacting the bottom of the abutment portion 2, thereby minimizing damage to the abutment portion 2 due to friction and scratches. Among them, after the abutment portion 2 expands, it absorbs and disperses external forces such as impact and friction, reducing the direct effects of these forces on the bottom of the bag body 1, thereby enhancing the wear resistance of the bag body 1.

[0026] In this embodiment, the bag body 1 and the abutment part 2 are detachably connected; when the user needs to replace or maintain the abutment part 2, the abutment part 2 can be removed from the bottom of the bag body 1 in a detachable manner, which is convenient for the user to replace or maintain the abutment part 2.

[0027] In this embodiment, an adhesive portion 1 6 is provided at the bottom of the bag body 1, and an adhesive portion 2 7 is provided at the top of the abutting portion 2, and the adhesive portion 1 6 and the adhesive portion 2 7 are adhered to each other; when the user needs to replace or maintain the abutting portion 2, the user can separate the abutting portion 2 from the bag body 1 by uncovering the connection between the adhesive portion 1 6 and the adhesive portion 2 7, so as to detach the abutting portion 2 from the bag body 1, making it easier for the user to replace or maintain the abutting portion 2.

[0028] In this embodiment, the bag body 1 is provided with a plurality of adhesive portions 3 8 at intervals, each of which is adapted to be attached to the abutting portion 2. The provision of the adhesive portions 3 8 allows the user to adjust the connection between the bag body 1 and the abutting portion 2 according to actual needs. For example, if the user needs to increase the support strength of the bottom of the bag body 1, they can attach more adhesive portions 3 8 to the abutting portion 2, thereby increasing the number of connection points between the two and improving the stability between the bag body 1 and the abutting portion 2. Conversely, if the user does not require high support strength, they can choose to attach only some of the adhesive portions 3 8 to simplify the operation. In short, the user can flexibly adjust the connection between the bag body 1 and the abutting portion 2 according to factors such as the specific type of goods, transportation distance, and usage environment to achieve the optimal use effect.

[0029] In this embodiment, a plurality of tightening holes 9 are provided at intervals along the length direction of the top of the bag body 1, and a tightening rope 10 crosses the tightening holes 9; when the user needs to load larger or more goods, the tightening rope 10 can be loosened to enlarge the opening of the bag body 1; when the user needs to load smaller or fewer goods, the tightening rope 10 can be tightened to make the opening of the bag body 1 smaller or even completely closed, thereby adapting to goods of different sizes to prevent the goods from slipping out or falling from the bag body 1 during transportation.

[0030] In this embodiment, the anti-scratch portion 5, the bag body 1, and the abutment portion 2 all have flexible structures. Because flexible materials have greater elasticity and toughness, they are better able to withstand external impacts and friction. When the bag body 1 is squeezed, rubbed, or impacted during transportation or storage, the flexible structure can absorb and disperse these forces, thereby reducing wear and damage to the material.

[0031] Working Principle: Before loading bag 1, the user first injects gas into inner cavity 3 through one-way gas valve 4, expanding the volume of inner cavity 3 and thereby increasing the support force of the bottom of abutment portion 2. As the amount of gas in inner cavity 3 increases, the bottom of abutment portion 2 becomes more solid, effectively preventing deformation or damage of bag 1 due to bottom pressure when loaded with heavy objects. During the transportation of the bag body 1, the anti-scratch portion 5 can prevent external media, such as sharp objects, rough surfaces, etc., from directly contacting the bottom of the abutting portion 2, thereby minimizing damage to the abutting portion 2 due to friction and scratching. After the abutting portion 2 expands, it absorbs and disperses external forces such as impact and friction, reducing the direct effects of these forces on the bottom of the bag body 1, thereby enhancing the wear resistance of the bag body 1; when the user needs to replace or maintain the abutting portion 2, the user can separate the abutting portion 2 from the bag body 1 by uncovering the connection between the adhesive portion 1 6 and the adhesive portion 2 7, so as to detach the abutting portion 2 from the bag body 1, making it easier for the user to replace or maintain the abutting portion 2, and the setting of the adhesive portion 3 8 allows the user to adjust the connection method between the bag body 1 and the abutting portion 2 according to actual needs. For example, when the user needs to increase the supporting force of the bottom of the bag body 1, more adhesive portions 3 8 can be pasted to the abutting portion 2, thereby increasing the connection points between the two and improving the stability between the bag body 1 and the abutting portion 2. Conversely, if the user does not require high support strength, they can choose to only partially adhere the adhesive portion 3 (8) to simplify operation. When loading larger or more cargo, the user can loosen the cinch cord 10 to enlarge the opening of the bag 1. When loading smaller or fewer cargo, the user can tighten the cinch cord 10 to reduce the opening of the bag 1 or even completely close it, thereby accommodating cargo of different sizes and preventing it from slipping out or falling out of the bag 1 during transportation. Because flexible materials have greater elasticity and toughness, they are better able to resist external impact and friction. When the bag 1 is squeezed, rubbed, or impacted during transportation or storage, the flexible structure can absorb and disperse these forces, thereby reducing wear and damage to the material.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
