Technical Field

[0001] This utility model relates to the field of packaging bag technology, and more specifically, to an environmentally friendly packaging bag. Background Technology

[0002] Packaging bags are bags used to package various products, making them convenient to store and retrieve during production, transportation, and sales. As people's environmental awareness gradually increases in today's society, people are reusing packaging bags. Among them, paper packaging bags are widely used in daily life and industrial production because they are relatively environmentally friendly. For example, customers use paper packaging bags to store shoes and clothing after purchasing them.

[0003] However, existing packaging bags come in a variety of types. For example, utility model patent CN203997322U relates to an environmentally friendly packaging bag suitable for various occasions. This utility model is equipped with a bag body, a partition plate, a sealing pull ring, and a sealing groove. The partition plate is located in the middle of the bag body, dividing the bag body into two placement chambers to form a multi-opening packaging bag. When walking, traveling, or on vacation, food with peels, pits, and shells can be placed in the inner bag and the peels, pits, and shells in the outer bag. After it is full, it can be thrown into a trash can. It is also convenient to carry, separate, and place. At the same time, a sealing groove is provided, and the sealing pull ring corresponds to the sealing groove and is set on the bag body. It can pass through the lower and upper openings of the sealing groove. Furthermore, the sealing pull ring can also be set on the partition plate, and there can be two or more of them. The sealing groove is set corresponding to the sealing pull ring and is set on the two side walls of the bag body, so that the sealing pull ring can close the placement chambers separately, so as to empty one side of the placement chamber, thereby increasing recycling and making it more convenient and environmentally friendly.

[0004] Although this packaging bag can separate the items and garbage inside the bag to avoid confusion, when the bag is lifted during use, due to its limited width, it is difficult to provide enough space to hold the items. The bag will squeeze the fragile items inside from both sides, causing damage. Therefore, it is essential to design an environmentally friendly packaging bag. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To achieve the above objectives, this utility model provides an environmentally friendly packaging bag, which is accomplished by the following specific technical means:

[0007] An environmentally friendly packaging bag includes a bag body. The inner wall of the bag body is fixed with a first fixed support plate and a second fixed support plate. The front of the first fixed support plate is provided with two symmetrical support crossbars through a hinge, and the support crossbars are located between the first fixed support plate and the second fixed support plate. One end of the support crossbar is fixedly connected to a locking block. The surface of the second fixed support plate opposite to the first fixed support plate is provided with two symmetrical mating grooves. The locking block can be embedded into the interior of the mating grooves. The inner surface of the mating grooves is provided with anti-slip pads.

[0008] Preferably, the two support crossbars are deflected to be perpendicular to the second fixed support plate so that the hemispherical block is inserted into the mating groove. The first fixed support plate, the second fixed support plate, and the two support crossbars can form a rectangular frame, and the block is hemispherical in shape.

[0009] Preferably, the first fixed support plate and the second fixed support plate are arranged symmetrically. The front of the first fixed support plate is provided with two first magnet pieces, and the surfaces of the two support crossbars that are close to each other are provided with second magnet pieces, and the second magnet pieces match the first magnet pieces.

[0010] Preferably, the bag body includes a paper base layer, a biofilm layer, and a waterproof and breathable membrane. The biofilm layer is provided on the outer side of the paper base layer and is made of polylactic acid material. The waterproof and breathable membrane is provided on the inner side of the paper base layer.

[0011] Preferably, the top of the bag body is fixedly connected to two symmetrical sealing skirts, the sealing skirts are provided with reinforcing strips, and the sealing skirts are provided with pull openings, which are located in the reinforcing strips.

[0012] Preferably, the two sealing skirts are provided with a female hook and loop fastener and a female hook and loop fastener respectively on their close-to-each surfaces, and the female hook and loop fastener and the female hook and loop fastener match each other, and the female hook and loop fastener and the female hook and loop fastener that are adhered to each other can seal the bag.

[0013] Preferably, limit plates are fixedly connected to both sides of the second fixed support plate, and the limit plates are used to limit the support crossbar during the deflection process; a secondary bag is provided on the front of the bag body.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] When packaging fragile items with a bag, the two support crossbars are deflected, squeezing the locking blocks during the deflection. When the support crossbars are deflected a quarter turn and are perpendicular to the second fixed support plate, the hemispherical locking blocks are inserted into the mating grooves. Anti-slip pads are used to prevent the locked blocks from easily slipping out of the mating grooves, thus completing the limiting and fixing of the deflected support crossbars. The first fixed support plate, the second fixed support plate, and the two support crossbars form a rectangular frame that supports the entire bag from the inside. Therefore, even if the bag is lifted, it can provide enough space to accommodate the items, avoiding the bag's width limitation from squeezing the items inside from both sides, thus preventing fragile items from being crushed.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0029] like Figure 2 , Figure 3 and Figure 4 The diagram shows the structure of the environmentally friendly packaging bag in this embodiment. The packaging bag includes a bag body 1. A first fixed support plate 2 and a second fixed support plate 3 are fixed to the inner wall of the bag body 1. Two symmetrical support crossbars 4 are hinged to the front of the first fixed support plate 2, and the support crossbars 4 are located between the first fixed support plate 2 and the second fixed support plate 3. A locking block 6 is fixedly connected to one end of each support crossbar 4. The locking block 6 is hemispherical in shape. Two symmetrical mating grooves 5 are formed on the surface of the second fixed support plate 3 opposite to the first fixed support plate 2. The locking block 6 can be embedded into the interior of the mating grooves 5. Anti-slip pads 7 are provided on the inner surface of each mating groove 5. When using the packaging bag to package fragile or easily damaged items… First, the two supporting crossbars 4 are deflected, which will squeeze the locking block 6. When the supporting crossbar 4 is deflected a quarter turn and is perpendicular to the second fixed support plate 3, the hemispherical locking block 6 is inserted into the mating groove 5. The anti-slip pad 7 is used to prevent the locked block 6 from easily slipping out of the mating groove 5, thus completing the limiting and fixing of the deflected supporting crossbar 4. The first fixed support plate 2, the second fixed support plate 3 and the two supporting crossbars 4 form a rectangular frame, which supports the entire bag body 1 from the inside. Thus, even if the packaging bag is lifted, it can provide enough space to accommodate the items, avoiding the packaging bag's width being limited and squeezing the items inside from both sides, thus preventing fragile items from being crushed.

[0030] It is worth noting that when the packaging bag is not in use and needs to be stored, you only need to apply a little force to deform the second fixing plate 3, and remove the hemispherical locking block 6 from the mating groove 5, thereby releasing the supporting effect on the packaging bag, so that the paper packaging bag can be folded and stored.

[0031] like Figure 2 As shown, in this embodiment, the first fixed support plate 2 and the second fixed support plate 3 are arranged symmetrically. The front of the first fixed support plate 2 is provided with two first magnet pieces 11, and the surfaces of the two support crossbars 4 that are close to each other are provided with second magnet pieces 12, and the second magnet pieces 12 match the first magnet pieces 11. In order to facilitate the folding of the paper packaging bag to be stored, the fixing effect of the clip 6 is first released, and then the support crossbar 4 is deflected again, so that the first magnet pieces 11 move closer to the direction of the second magnet pieces 12. The magnetic attraction is used to fix the first magnet pieces 11 and the second magnet pieces 12, so that the support crossbar 4 is parallel to the first fixed support plate 2 and is folded up.

[0032] like Figure 5 and Figure 6 As shown, in this embodiment, the bag body 1 includes a paper base layer 14, a biofilm layer 15, and a waterproof and breathable membrane 16. The biofilm layer 15 is provided on the outer side of the paper base layer 14, and the biofilm layer 15 is made of polylactic acid material. The waterproof and breathable membrane 16 is provided on the inner side of the paper base layer 14. By providing the outer biofilm layer 15, the unique molecular structure and excellent biodegradability of polylactic acid material help reduce plastic pollution, protect the environment, and further improve the environmental friendliness of the entire paper packaging bag. The inner waterproof and breathable membrane 16 helps improve the waterproof performance inside the paper packaging bag.

[0033] like Figure 1 and Figure 8 As shown, in this embodiment, the top of the bag body 1 is fixedly connected to two symmetrical sealing skirts 8. A reinforcing band 9 is provided through the sealing skirts 8, and a pull opening 10 is installed through the sealing skirts 8, with the pull opening 10 located in the reinforcing band 9. The surfaces of the two sealing skirts 8 that are close to each other are respectively provided with a female hook and loop fastener 17 and a female hook and loop fastener 18, and the female hook and loop fastener 17 and the female hook and loop fastener 18 are matched. The female hook and loop fastener 17 and the female hook and loop fastener 18, which are bonded to each other, can seal the bag body 1. When using this packaging bag to store items, the packaging bag can be lifted through the pull opening 10, and the sealing skirts 8 are reinforced by the reinforcing band 9 to prevent the sealing skirts 8 from tearing at the pull opening 10 under stress.

[0034] It is worth noting that, such as Figure 7 As shown, in this embodiment, the second fixed support plate 3 is fixedly connected to both sides of the limiting plate 13. The limiting plate 13 is used to limit the support crossbar 4 during the deflection process. The front of the bag body 1 is provided with a secondary bag 19. The secondary bag 19 can be used to store items that are not convenient to put into the bag body 1.

[0035] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
