Technical Field

[0001] The utility model relates to the technical field of guarantee bags, in particular to a multi-purpose three-dimensional packaging bag. Background Art

[0002] Common plastic film packaging bags mainly provide simple wrapping protection and packaging functions;

[0003] However, existing plastic film packaging bags have relatively simple functions and are generally suitable for light, non-fragile items. They cannot provide additional cushioning protection functions, nor can they ensure that the items remain stable when packaging irregularly shaped items. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In order to solve the above-mentioned problems, the utility model provides the following technical solutions: a three-dimensional packaging bag comprises a bag body and a bag cavity formed when the bag body is unfolded, characterized in that a sealing strip is provided at the opening of the bag body, and an expansion body is provided on the side of the bag body, and when the sealing strip blocks the bag cavity, the bag cavity is connected with the cavity of the expansion body through an airway, so that the expansion body expands;

[0006] When the bag is turned over, the expansion body is located in the bag cavity, and the airway is located outside the bag body. The airway of the bag body is blocked to make the cavity of the expansion body, and the airway of the bag body is sealed and opened to make the expansion body shrink.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] As a preferred solution of the three-dimensional packaging bag of the utility model, the expansion body is sealed and partitioned by a partition area to form a plurality of chambers, and the chambers are connected to each other through grooves opened in the partition area.

[0009] As a preferred solution of the three-dimensional packaging bag of the utility model, each of the partition areas is provided with a single through slot, and the positions of the through slots corresponding to the partition areas are staggered with each other, and the channel formed by the through slot and the bag body is a narrow hole.

[0010] As a preferred solution of the three-dimensional packaging bag of the utility model, there are two sealing strips, and the sealing strips are made of flexible material.

[0011] As a preferred solution of the three-dimensional packaging bag of the utility model, wherein: the connection area of ​​the sealing strip is connected to the opening of the bag body, and the connection area is located at the bottom of the sealing strip.

[0012] As a preferred solution of the three-dimensional packaging bag of the utility model, the raised area of ​​one sealing strip is snapped with the recessed area of ​​another sealing strip, and when the bag is turned over, the recessed area of ​​one sealing strip is snapped with the raised area of ​​another sealing strip.

[0013] As a preferred solution of the three-dimensional packaging bag of the utility model, the air passage of the bag cavity is a micropore opened in the bag body, and the diameter of the micropore is between 1-2 mm.

[0014] The beneficial effects of the utility model are as follows: items are placed in the unfolded bag cavity, and then the sealing strip is closed to seal the bag cavity, and then the air in the bag cavity is squeezed to allow the gas to expand through the airway expansion body, so that when the packaging bag is used, cushioning protection for the items can be provided during transportation. A second method is to keep the expansion body in its original state, and then turn the packaging bag over so that the expansion body faces the bag cavity, and then use transparent tape and other materials to seal the airway between the two, and place the items in the bag cavity, which can also achieve the same cushioning effect. The difference is that for small and irregularly shaped items, the expansion body can wrap the items more tightly during packaging. A third method is that the expansion body is always in a contracted state regardless of whether the packaging bag is flipped over. In this case, a common plastic film packaging bag is used, thereby achieving the purpose of one bag with multiple uses. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example

[0029] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides a three-dimensional packaging bag, a bag body 100, and a bag cavity 100a formed after the bag body 100 is unfolded, characterized in that: a sealing strip 200 is provided at the opening of the bag body 100, and an expansion body 101 is provided on the side of the bag body 100. When the sealing strip 200 blocks the bag cavity 100a, the bag cavity 100a is connected to the chamber 101a of the expansion body 101 through the airway, so that the expansion body 101 expands;

[0030] When the bag is turned over, the expansion body 101 is located in the bag cavity 100a, and the airway is located outside the bag body 100, the airway of the bag body 100 is blocked to seal the chamber 101a of the expansion body 101, and the airway of the bag body 100 is opened to shrink the expansion body 101;

[0031] Specifically, the preferred expansion body 101 is made of the same material as the bag body 100, which is also a plastic film. The article is placed in the bag cavity 100a after the bag body 100 is unfolded, and the sealing strip 200 is closed to seal the bag cavity 100a, and then the air in the bag cavity 100a is squeezed to allow the gas to pass through the airway to expand the expansion body 101. In this way, the expansion body can play a role in buffering and protecting the articles when the articles are transported after the packaging bag is used. The second method is to keep the state of the above-mentioned expansion body, then turn the packaging bag over, let the expansion body face the bag cavity 100a, and then seal the airway connecting the two with transparent tape, and then put the articles into the bag cavity 100a. This still has the same buffering effect on the transported articles. The difference is that when packaging some smaller and irregularly shaped articles, the expansion body can tightly wrap the smaller and irregular articles. There is also a method in which the expansion body is in a contracted state regardless of whether the packaging bag is turned over. At this time, the packaging bag is a common plastic film packaging bag.

[0032] The air passage of the bag cavity 100a is a micropore 100b opened in the bag body 100, and the pore size of the micropore 100b is between 1-2 mm, which can well prevent the gas in the expansion body 101 from excessively flowing back into the bag cavity when the expansion body 101 is hit, and the small pores are more likely to maintain the expansion state of the expansion body 101;

[0033] Furthermore, the expansion body 101 is sealed and partitioned by the partition area 101b to form a plurality of chambers 101a, and the chambers 101a are connected to each other through the through grooves 101b-1 opened in the partition area 101b, each of the partition areas 101b is provided with a single through groove 101b-1, and the positions of the through grooves 101b-1 corresponding to the partition area 101b are staggered, and the channel formed by the through grooves 101b-1 and the bag body 100 is a narrow hole;

[0034] Similarly, the expansion bodies 101 on each outer surface of the bag body are separated and connected by tiny air passages, which can further prevent the gas of the expansion body 101 from excessively flowing back into the bag cavity when the expansion body 101 is hit, so as to maintain the expansion state of the expansion body 101;

[0035] Further, the number of the sealing strips 200 is two, and the sealing strips 200 are made of flexible material. The connection area 201 of the sealing strips 200 is connected to the opening of the bag body 100, and the connection area 201 is located at the bottom of the sealing strips 200. The raised area 202 of one sealing strip 200 is engaged with the recessed area 203 of the other sealing strip 200. When the bag is turned over, the recessed area 203 of one sealing strip 200 is engaged with the raised area 202 of the other sealing strip 200.

[0036] The same sealing strip 200 has both a raised area 202 and a recessed area 203, which ensures that the two sealing strips 200 can seal the bag cavity 100a of the bag body 100 when the bag is turned over. The connecting area 201 at the bottom of the sealing strip 200 is used, on the one hand, to enable the two sealing strips 200 to seal the bag cavity 100a of the bag body 100 when the bag is turned over, and on the other hand, to make the connecting area 201 thinner and easier to bend at any angle with the expansion body 101 during use, so as to facilitate the storage of articles in the bag cavity 100a of the bag body 100 and the sealing of the bag cavity 100a of the bag body 100.

[0037] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.
