[0043] The purpose of the present application is to solve the problems of cumbersome hanging operation, poor transport stability, easy tilting or toppling of the packaging bag in the prior art when being hung and transported, especially when being delivered by a delivery robot.

[0044] To this end, the present application provides a hanging packaging bag, which comprises a bag body having a bottom wall and side walls to form a containing space, and a cover body arranged at the opening end of the bag body in the height direction, wherein at least part of the edge of the cover body is reversibly connected with the side wall, and the remaining part of the edge is separably connected with the side wall through a separable connecting structure. In addition, a hanging component is arranged on the side of the cover body away from the bottom wall, one end of which is connected to the cover body, and the other end forms a hanging part. More importantly, in the height direction of the bag body, the geometric center of the bag body is designed to be located within the projection area of the hanging part, which can solve the problems of difficult hanging and poor transport stability in the prior art.

[0045] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0046] Please refer to Figures 1 to 3The suspension type packaging bag provided by the application comprises a bag body 100, a cover body 200 and a suspension component 300. The bag body 100 has a bottom wall 110 and a side wall surrounding the side edge of the bottom wall 110 in the height direction of the bag body 100. The bottom wall 110 and the side wall form a containing space. The cover body 200 is arranged on the opening end of the bag body 100 opposite to the bottom wall 110 in the height direction. At least part of the edge of the cover body 200 is reversibly connected with the corresponding part of the side wall. The remaining part of the edge of the cover body 200 is detachably connected with the corresponding part of the side wall through a detachable connection structure 210. The suspension component 300 is arranged on the side of the cover body 200 away from the bottom wall 110. One end of the suspension component 300 is connected with the cover body 200, and the other end forms a suspension part. In the height direction of the bag body 100, the geometric center of the bag body 100 is located in the projection area of the suspension part.

[0047] Specifically, in the application, the bag body 100 refers to the main structure for containing articles, which is formed by the bottom wall 110 and the side wall to form an internal containing space. It is used for containing articles to be transported. For example, the bottom wall 110 can be a planar structure, and the side wall can be made of flexible material and extend upward to form an open container.

[0048] The cover body 200 refers to the component for covering the opening end of the bag body 100, which functions to close the containing space and protect the internal articles. The cover body 200 is connected with the side wall of the bag body 100 through a specific connection mode to realize the opening and closing functions.

[0049] The suspension component 300 refers to the structure arranged outside the cover body 200, which is used for suspending the packaging bag. The component can include a connection part and a suspension part. The connection part is fixed with the cover body 200, and the suspension part can provide an interface for external mounting. Specifically, one end of the suspension component 300 is connected with the cover body 200, and the other end forms a suspension part. For example, the suspension component 300 can be a simple ring structure. One end of the ring structure is fixed on the outer surface of the cover body 200, and the other end forms an open ring to facilitate the suspension of external hooks or rods. Alternatively, the suspension component 300 can also be a plate structure with a hole. The plate structure is fixed on the cover body 200 through bolts or rivets, and the hole is the suspension part.

[0050] The reversibly connected part of the at least part of the edge of the cover 200 and the corresponding part of the side wall can be understood as allowing the cover 200 to rotate or bend around the connection part when the cover 200 is connected, so as to realize the opening or inwardly turning of the cover 200. For example, one side edge of the cover 200 can be integrally connected with the top edge of the side wall by a flexible material, or connected by a hinge structure, so that the cover 200 can be turned around the connection part. The remaining part of the edge of the cover 200 is reversibly connected with the corresponding part of the side wall by the separable connection structure 210.

[0051] Further, the remaining part of the edge of the cover 200 is reversibly connected with the corresponding part of the side wall by the separable connection structure 210, which can be understood as allowing the remaining part of the cover 200 to be separated from the side wall when needed, and reconnected when not needed, so as to realize the sealing of the cover 200 to the bag 100. For example, the temporary fixing and separation of the cover 200 and the side wall can be realized by a touch fastener, a snap, a zipper, a magnetic fastener or a simple adhesive.

[0052] Further, the geometric center of the bag 100 is designed to be located in the projection area of the hanging part; wherein the geometric center refers to the center of gravity position of the bag 100 in three-dimensional space, representing the average point of the mass distribution of the bag 100. The projection area refers to the range covered by the vertical projection of the hanging part on the horizontal plane. When the packaging bag is hung, the projection area of the hanging part is the effective area in contact with the external hanging device, which helps to maintain the balance of the packaging bag in the hanging state and reduces its inclination or shaking.

[0053] The packaging bag provided by the present application has the following advantages. The bag 100 is composed of a bottom wall 110 and a side wall to form a containing space, providing a stable basic container. The cover 200 is arranged at the opening end, and part of the edge thereof is reversibly connected to facilitate the opening and closing of the cover 200 by the user. The at least part of the edge of the cover 200 is reversibly connected with the side wall, and the remaining part is reversibly connected with the side wall by the separable connection structure 210. When not in use, the separable connection structure 210 can be released, and the cover 200 can be turned inward around the connection part into the containing space of the bag 100 and attached to the inner wall surface of the side wall for storage. When in use, the remaining part can be fixed by the separable connection structure 210 while realizing the sealing of the bag 100, so as to avoid accidental opening during transportation. The hanging part 300 is fixed to the side of the cover 200 away from the bottom wall 110, forming a hanging part that can be used for external mounting, which can simplify the hanging operation without the need for manual assistance. Further, the geometric center of the bag 100 is located in the projection area of the hanging part, so that the center of gravity is aligned with the hanging point when the bag is hung, which is better balanced and effectively prevents tilting and pouring, thereby improving the overall stability during transportation. Therefore, the present application improves the balance of the packaging bag during hanging on the basis of improving the convenience of the packaging bag during hanging.

[0054] For the hanging packaging bag provided in the present application, in some embodiments, in the height direction, the edge of the remaining part of the cover 200 is aligned with the edge of the opening end of the side wall; or the edge of the remaining part of the cover 200 is located inside the edge of the opening end of the side wall; and the cover 200 can be arranged on the opening end or turned inward to the accommodation space and attached to the inner wall surface of the side wall around the part connected with the side wall.

[0055] Specifically, in the present embodiment, the relative position relationship between the edge of the remaining part of the cover 200 and the edge of the opening end of the side wall can have two implementation manners. The first manner is that the edge of the remaining part of the cover 200 is aligned with the edge of the opening end of the side wall. When the cover 200 is closed, the non-connected edge thereof is in the same plane as the top edge of the side wall, forming a flat closed surface. The second manner is that the edge of the remaining part of the cover 200 is located inside the edge of the opening end of the side wall. In this case, the non-connected edge of the cover 200 is slightly smaller than the size of the opening end of the side wall, so that the cover 200 can be partially or completely embedded into the inside of the opening end of the side wall when closed. For example, an annular groove or step can be arranged inside the opening end of the side wall, so that the edge of the cover 200 can be clamped therein, or the cover 200 can be simply designed to be slightly smaller than the opening size, so as to be embedded.

[0056] Through such a structure, the cover 200 can be conveniently turned around the part connected with the side wall to achieve two main states. For example, the first state is that the cover is arranged on the opening end, i.e., the cover 200 is rotated through the turnable connecting part (e.g., a flexible crease or a hinge structure) thereof, so that the main body part thereof covers the opening end of the bag body 100, thereby closing the accommodation space. At this time, the edge of the remaining part of the cover 200 is aligned with or located inside the edge of the opening end of the side wall. The second state is that the cover 200 is turned inward to the accommodation space and attached to the inner wall surface of the side wall. When the packaging bag is not used or needs to be stored, the cover 200 can be turned inward to the inside of the bag body 100. After turning, the plane of the cover 200 is closely attached to the inner wall surface of the side wall, for example, the cover 200 can be folded downward along the inner surface of the side wall until it is parallel to or closely contacts with the inner wall surface of the side wall, so that the cover 200 can be smoothly folded.

[0057] By using the above technical solutions of the embodiment, the accurate alignment or inner positioning of the remaining edge of the cover body 200 with the edge of the open end of the side wall effectively solves the problem that the edge of the cover body 200 cannot be accurately matched. When the cover body 200 is closed, the cover body 200 forms a tight and stable fit with the side wall, which is beneficial to the sealing performance of the packaging bag and can prevent the objects in the packaging bag from overflowing or being affected by the external environment, thereby enhancing the overall stability of the packaging bag during transportation and use. At the same time, the design that the cover body 200 can be turned inward to the accommodation space and fit the inner wall surface of the side wall can improve the storage convenience and operation flexibility of the packaging bag. When the packaging bag is idle or needs to be folded, the cover body 200 can be completely folded into the bag body 100, avoiding the cover body 200 from being exposed or hindering folding, effectively reducing the overall volume of the packaging bag, facilitating storage and transportation, and can improve the functionality and user experience of the packaging bag at the same time.

[0058] For the hanging packaging bag provided in the present application, in some embodiments, referring to Figure 1 and Figure 2 , the bottom wall 110 is rectangular, and the side wall includes a pair of first side walls 121 and a pair of second side walls 122; wherein the pair of first side walls 121 are oppositely arranged along the length direction of the bottom wall 110, and the pair of second side walls 122 are oppositely arranged along the width direction of the bottom wall 110; the cover body 200 is rectangular corresponding to the open end, and one side edge is reversibly connected to the top edge of one first side wall 121, and the other edges of the cover body 200 are respectively and separably connected to the top edges of the other first side wall 121 and the pair of second side walls 122.

[0059] Specifically, the rectangular bottom wall 110 means that the bottom of the bag body 100 has a regular quadrilateral structure with all four corners being right angles. The bottom wall 110 can be made of various materials, for example, flexible materials such as non-woven fabric, polyester fiber, etc. can be used to form a rectangle by sewing or hot pressing; or semi-rigid or rigid materials such as plastic plates, hardboard, etc. can be used to provide stronger bottom support. The rectangular structure of the bottom wall 110 can provide a stable foundation for the bag body 100, which helps to maintain balance when placed.

[0060] The side walls include a pair of first side walls 121 and a pair of second side walls 122, which together form the enclosure of the bag 100. The side walls can be made of the same material as the bottom wall 110, or a different material. For example, the side walls can be made of a flexible fabric material, or a plastic film or composite material with a certain stiffness. The side walls can be formed by four separate pieces of material, or by a single piece of material that is folded and connected. The pair of first side walls 121 are arranged opposite each other along the length of the bottom wall 110, and the pair of second side walls 122 are arranged opposite each other along the width of the bottom wall 110, so that the bag 100 has a rectangular columnar structure that matches the rectangular bottom wall 110. For example, if the bottom wall 110 is rectangular, the pair of first side walls 121 can correspond to the longer sides, and the pair of second side walls 122 can correspond to the shorter sides. This regular geometric shape facilitates the stacking, storage, and transportation of the bag 100, and effectively utilizes the internal storage space. The cover 200 is rectangular and corresponds to the open end, so that the shape and size of the cover 200 match the profile of the open end of the bag 100, and the cover 200 can tightly cover the open end. The cover 200 can be made of various materials, such as a hard plastic plate, a composite material plate, or a fabric material with a certain stiffness.

[0061] One side edge of the cover 200 is reversibly connected to the top edge of one of the first side walls 121, so that the cover 200 can be opened and closed like a door around the connection edge. For example, the reversible connection can be achieved in the following ways: first, a flexible connection band or fabric hinge is provided between the cover 200 and the top edge of the first side wall 121; second, the cover 200 and the top edge of the first side wall 121 are connected by an integrally formed film or crease structure to form a living hinge; third, the side edge of the cover 200 is connected to the top edge of the first side wall 121 by a mechanical hinge structure. This reversible connection ensures that the cover 200 does not separate from the bag 100 when opened, making it convenient for users to take out or put in items.

[0062] The other edges of the cover body 200 are respectively detachably connected with the top edges of the other first side wall 121 and the pair of second side walls 122. It can be understood that, in addition to the side of the flip-over connection, the other three edges of the cover body 200 can be temporarily fixed and released with the top edges of the corresponding side walls. For example, the detachable connection can be achieved in the following ways: (1) using a magic tape or a hook-and-loop fastener, the hook surface and the loop surface are respectively arranged on the edges of the cover body 200 and the top edges of the side walls, and the connection is achieved by pressing and the separation is achieved by tearing; (2) using a self-adhesive tape or a reusable adhesive, the edges of the cover body 200 and the top edges of the side walls are coated or pasted, and the adhesion is achieved by contact and the separation is achieved by pulling; (3) using a mechanical connection such as a snap, a buckle or a zipper, the connection is achieved by buckling or pulling, and the separation is achieved by unbuckling or pulling open. Such a detachable connection enables the cover body 200 to be firmly fixed on the bag body 100 when closed, and to be conveniently and quickly opened when needed.

[0063] Through the above technical solutions provided by the embodiment, the rectangular structure of the bottom wall 110 and the corresponding arrangement of the side walls enable the bag body 100 to have a regular geometric shape, improving the overall structural stability and containing efficiency. The cover body 200 is designed with one side edge of flip-over connection and the other edges of detachable connection, solving the problem of inconvenience caused by the traditional connection method of the cover body 200 of the packaging bag. When it is needed to take or place the articles, the user only needs to release the detachable connection, and then open the cover body 200 along the flip-over connection, which is simple and convenient to operate. During the hanging and conveying process, the detachable connection of the other edges of the cover body 200 with the side walls can provide multi-point fixation, ensuring that the cover body 200 is tightly combined with the bag body 100, effectively preventing the cover body 200 from being accidentally opened when shaking or tilting, thereby avoiding the scattering or displacement of the internal articles. Such a stable connection method of the cover body 200, in combination with the design that the geometric center of the bag body 100 is located within the projection area of the hanging part, further enhances the overall stability in the hanging state, effectively reducing the risk of tilting or toppling of the bag body 100 during the conveying process, thereby improving the stability of the conveying.

[0064] For the hanging packaging bag provided by the present application, in some embodiments, see Figure 1 The detachable connection structure 210 includes a connection wall 123 extending outward from the top edges of the other first side wall 121 and the pair of second side walls 122, and an adhesive component arranged on the inner side surface of the connection wall 123.

[0065] Specifically, the connecting wall 123 can be understood as a structure extending outward from the top edge of the side wall of the bag body 100, which mainly provides a connection interface for the cover body 200 to facilitate the reliable fixation of the cover body 200 and the bag body 100. The connecting wall 123 can be implemented in various forms, for example, it can be a rigid flange integrally formed with the side wall, formed by molding or hot pressing process, to provide a stable support and connection surface. In addition, the connecting wall 123 can also be a flexible sheet extending from the top edge of the side wall, which can be made of the same material as the side wall, or attached to the side wall by bonding, sewing or other means, which can be neatly stored when not in use, and provides the necessary bonding area when connected.

[0066] The adhesive component is a material or structure provided on the surface of the connecting wall 123 for realizing the detachable connection between the cover body 200 and the connecting wall 123. The adhesive component can be a glue layer pre-coated on the inner side surface of the connecting wall 123 and bonded with the cover body 200 by removing the protective film when in use. Another implementation is that the adhesive component can adopt a mechanical bonding structure, for example, a micro-hook structure is provided on the inner side surface of the connecting wall 123, which cooperates with the corresponding ring structure on the cover body 200 to form a repeatedly openable and closable connection.

[0067] Through the above technical solutions provided by the embodiment, the detachable connection structure 210 provides a clear and easy-to-operate connection interface for the cover body 200 and the side wall of the bag body 100 by setting the connecting wall 123 extending outward from the top edge of the side wall and setting the adhesive component on the inner side surface thereof. This design enables the cover body 200 to be fixed with the bag body 100 conveniently and quickly when it needs to be closed, ensuring the safety of the items in the containing space. When the items need to be taken, the user can easily detach the cover body 200, and the operation process is more smooth and convenient.

[0068] Further, the presence of the connecting wall 123 provides a stable attachment basis for the adhesive component, which helps to improve the reliability and durability of the adhesive, thereby effectively avoiding the risk of items falling or scattering due to unstable connection. In addition, the adhesive component is arranged on the inner side surface of the connecting wall 123, and the inner side surface of the connecting wall 123 refers to the side surface close to the cover body 200.

[0069] For the hanging packaging bag provided by the present application, regarding the connecting wall 123, in some embodiments, the connecting wall 123 is a folding edge extending outward from the top edge of another first side wall 121, a pair of second side walls 122, and being foldable about the top edge; and one side edge of the cover body 200 is fixedly connected with the top edge of one first side wall 121, and the cover body 200 is foldable relative to the top edge of one first side wall 121.

[0070] Specifically, the connecting wall 123 is designed as a folded edge extending outward from the top edge of the other first side wall 121 and the pair of second side walls 122 of the bag body 100. Such a folded edge structure makes the connecting wall 123 have good flexibility, which can be conveniently bent around the top edge. The folded edge can be realized in various ways, for example, it can be formed by indentation, line marking or local thinning treatment on the side wall material, thereby providing an easy-to-bend area while maintaining the continuity of the material; or the folded edge can also be composed of a material area with higher flexibility integrally formed with the side wall material. Such a design enables the connecting wall 123 to smoothly cooperate when the cover 200 is opened or closed, avoiding the possibility of jamming or obstruction due to rigid connection.

[0071] Further, the side edge of the cover 200 and the top edge of the first side wall 121 are fixedly connected, but the fixed connection allows the cover 200 to be bent relative to the top edge of the first side wall 121.

[0072] It should be understood that in the present embodiment, such a fixed connection is not a rigid connection, but a connection with a certain flexibility, for example, it can be realized by an integrally formed living hinge structure, in which the cover 200 and the side wall are connected by a film or flexible material at the connection, thereby allowing the cover 200 to be flipped and bent; or it can also be realized by using a flexible fabric, film or other material as a connecting piece, and firmly bonding, sewing or welding the two ends of the connecting piece to the edge of the cover 200 and the top edge of the side wall, thereby forming a fixed and bendable connection. Such a design enables the cover 200 to be stably flipped when opened, and even flipped inward to the accommodation space and attached to the inner wall of the side wall, thereby providing greater convenience for the user.

[0073] By the above technical solutions provided in the present embodiment, the connecting wall 123 is designed as a bendable folded edge, and the connection between the cover 200 and the side wall is both fixed and bendable, effectively solving the problem of insufficient flexibility that may exist in the traditional connecting wall 123. Such a structure enables the cover 200 to be more smooth when opened and closed, and more convenient to operate, avoiding the inconvenience of opening and closing due to the excessive rigidity of the connecting wall 123. In addition, when the cover 200 needs to be flipped inward and attached to the inner wall of the accommodation space, the folded edge and the bendable fixed connection can provide the necessary flexibility, so that the cover 200 can be stably accommodated, thereby reducing the possibility of the cover 200 shaking or accidentally opening during the hanging and conveying process, and improving the overall stability and safety of the packaging bag.

[0074] For the hanging packaging bag provided in the present application, the structure of the adhesive component is not limited, for example, the adhesive component includes a magic tape or double-sided tape.

[0075] Specifically, when the adhesive component is a magic tape, the hook surface and the loop surface of the magic tape can be respectively arranged on the lower surface of the edge of the cover body 200 and the inner surface of the folded edge of the side wall, so that the cover body 200 and the bag body 100 are tightly connected by pressing and can be repeatedly separated. When the adhesive component is a double-sided tape, the double-sided tape strip can be arranged on the lower surface of the edge of the cover body 200 or the inner surface of the folded edge of the side wall. In use, the protective film is torn to achieve adhesion, thereby providing firm connection and allowing manual peeling when needed. Both of the above-mentioned adhesive methods can provide reliable and separable connection, so as to ensure that the cover body 200 is tightly fixed to the bag body 100 in the closed state, thereby reducing the risk of accidental separation of the cover body 200 from the bag body 100 due to vibration or external force during transportation of the packaging bag.

[0076] The structure of the cover body 200 is not limited. For example, the cover body 200 is a plate structure, and the elastic modulus of the material of the cover body 200 is greater than that of the material of the bag body 100. For example, the cover body 200 can be a flat plate material with a certain thickness, such as a hard plastic plate material, and the bag body 100 can be a flexible material, such as a non-woven fabric. Through this design, the cover body 200 can provide sufficient rigidity to resist external pressure and its own weight, thereby maintaining its shape in the hanging state and avoiding deformation. The risk of deformation of the cover body 200 caused by uneven weight distribution when hanging can be reduced, which is beneficial to improve the stability of the packaging bag during hanging transportation.

[0077] For example, the cover body 200 is made of a hard plastic plate material, and the bag body 100 is made of a non-woven fabric material. The hard plastic plate can be, for example, a polypropylene (PP) plate or a polyvinyl chloride (PVC) plate, which has high hardness, strength and durability, can provide a stable support basis for the hanging component 300, and effectively maintain the overall structural stability of the cover body 200. The non-woven fabric material can be, for example, a polypropylene (PP) non-woven fabric or a polyester (PET) non-woven fabric, which has the characteristics of light weight and flexibility, facilitating the folding, storage and carrying of the bag body 100, while still providing sufficient strength to accommodate articles, and using its light weight and flexibility can facilitate the folding and storage of the bag body 100.

[0078] Further, in the hanging packaging bag provided in the present application, the inner wall or the outer wall of the bag body 100 further has a heat preservation layer (not shown) stacked thereon.

[0079] The structure of the heat preservation layer is not limited. For example, the heat preservation layer can be made of aluminum foil, pearl wool, expanded polyethylene (EPE) or polyurethane foam, and is fixed on the bag body 100 by adhesion, sewing or hot pressing. The heat preservation layer can effectively reduce heat transfer, thereby maintaining the temperature of the articles in the bag during transportation, for example, food preservation or cold storage, and can also enhance the structural strength of the bag body 100.

[0080] Further, the bottom of the bag body 100 is further provided with a bottom reinforcing structure 130, and the material elastic modulus of the bottom reinforcing structure 130 is greater than the material elastic modulus of the bottom wall 110.

[0081] The structure of the bottom reinforcing structure 130 is not limited, for example, it can be a plastic paperboard, a plastic honeycomb board, and is detachably arranged on the bottom of the containing space and above the bottom wall 110.

[0082] Specifically, the bottom reinforcing structure 130 is an additional support component arranged at the bottom of the bag body 100, which mainly functions to enhance the rigidity and load-bearing capacity of the bottom of the bag body 100, and prevent the bag body 100 from deforming or collapsing when hanging or bearing heavy objects. The bottom reinforcing structure 130 can take various forms, for example, in addition to plastic paperboard and plastic honeycomb board, it can also be a metal grid plate or a multi-layer composite material plate, etc., as long as it can provide sufficient support strength.

[0083] Further, the material elastic modulus of the bottom reinforcing structure 130 being greater than the material elastic modulus of the bottom wall 110 can be understood as the bottom reinforcing structure 130 being harder and less likely to deform than the bottom wall 110. For example, if the bottom wall 110 is made of a flexible material (such as non-woven fabric), the bottom reinforcing structure 130 will be made of a harder material (such as plastic) to ensure that it can effectively support the load. The bottom reinforcing structure 130 is specifically a plastic honeycomb board, which is a kind of lightweight high-strength composite material, and can be bonded by a honeycomb core material and two upper and lower panels. The plastic honeycomb board has excellent compression and bending resistance, and at the same time is light in weight, which can effectively improve the bottom strength without significantly increasing the overall weight.

[0084] The bottom reinforcing structure 130 is detachably arranged on the bottom of the containing space and above the bottom wall 110, which can be understood as the bottom reinforcing structure 130 being conveniently put in or taken out. For example, the bottom reinforcing structure 130 can be simply placed at the bottom of the containing space and positioned by relying on its own size and the cooperation with the bottom wall 110; or it can also be fixed through magic tape, buckle, or a guide groove arranged on the inner wall of the bag body 100, etc., so as to facilitate the user to install or disassemble according to the needs.

[0085] By means of the technical scheme provided in the embodiment, the bottom of the hanging packaging bag is provided with a bottom reinforcing structure 130 with higher elastic modulus, in particular, a plastic honeycomb plate is used, which can improve the overall rigidity and load-bearing capacity of the bottom of the bag body 100, reduce the risk of deformation or movement of the contents of the bag body 100 due to insufficient strength of the bottom of the bag body 100 during hanging transportation, and thus improve the stability and safety of the packaging bag in the hanging state. At the same time, the bottom reinforcing structure 130 is designed to be detachable, so that the packaging bag can be conveniently removed from the reinforcing structure when not in use, thereby realizing the folding and storage of the bag body 100 and saving storage space; and when needed, it can be quickly installed to provide immediate and reliable bottom support for the bag body 100, thereby improving the practicality and convenience of the packaging bag.

[0086] Further, in the hanging packaging bag provided in the present application, please refer to Figure 1 and Figure 2 a first crease 124 extending in the height direction is formed on the pair of second side walls 122, and a second crease 111 extending in the width direction of the bag body 100 is formed on the bottom wall 110 and connected to the first crease 124, and the bag body 100 can be folded into a flat shape along the first crease 124 and the second crease 111.

[0087] Specifically, on the pair of second side walls 122 of the bag body 100 of the above-mentioned hanging packaging bag, a first crease 124 capable of guiding the side wall to bend in the height direction thereof is provided, and a second crease 111 connected to the first crease 124 in structure and extending in the width direction of the bag body 100 is provided, which can provide a clear bending path when the packaging bag needs to be folded, so that the side wall can be accurately folded, thereby effectively reducing the lateral dimension of the bag body 100 after folding. The second crease 111 can make the bottom wall 110 consistent with the folding action of the side wall during the folding process, avoiding problems such as material accumulation, structural misplacement or uneven folding during folding, thereby ensuring smooth folding of the entire bag body 100.

[0088] More specifically, in the embodiment, the forming method of the first crease 124 can include but is not limited to: forming one or more linear regions that are easy to bend by performing indentation processing on the side wall material; or locally weakening the material at a specific position of the side wall material, for example, using laser marking or chemical etching, etc., to reduce the bending stiffness of the region, so that it bends preferentially when stressed. The implementation method of the second crease 111 can include but is not limited to: forming one or more pre-set folding lines on the material of the bottom wall 110 by molding or mechanical pressing; or embedding flexible connectors or hinge structures in the material of the bottom wall 110, which provide a clear bending axis during folding and are accurately aligned or connected with the end of the first crease 124.

[0089] It needs to be understood that, in order to avoid the bag body from bulging when being folded, see Figure 1 The two ends of the second crease 111 can also be provided with auxiliary creases extending obliquely relative to the second crease 111.

[0090] The first crease 124 and the second crease 111 cooperate to make the bag body 100 of the hanging packaging bag change from the original three-dimensional form to a two-dimensional flat form. Specifically, when the packaging bag needs to be stored or transported, the user can fold the side wall inward or outward along the preset first crease 124, and fold the bottom wall 110 along the second crease 111 connected with the first crease 124. The occupied space can be greatly reduced, which is conducive to the storage, transportation and batch distribution of the packaging bag.

[0091] In the present application, the structure of the hanging component 300 is not limited, for example, it can be provided as an integrated structure, or as a split structure.

[0092] In one embodiment, please see Figures 1 to 3 The hanging component 300 includes a connecting column 310 and a hanging arm 311; the connecting column 310 extends in the height direction, and one end of the connecting column 310 is fixedly connected to the cover body 200; the hanging arm 311 extends in the vertical direction perpendicular to the height direction and is fixedly connected to the other end of the connecting column 310, and the hanging arm 311 and the wall surface of the cover body 200 form a hanging position 3111.

[0093] Specifically, the connecting column 310 and the hanging arm 311 can be manufactured in an integrated manner, for example, by injection molding, to ensure the structural strength and the firmness of the connection; or the connecting column 310 and the hanging arm 311 can also be independently manufactured and combined together by mechanical connection (such as bolts, rivets) or welding, etc., to facilitate the flexibility of material selection and manufacturing process.

[0094] The connecting column 310 extends in the height direction, which means that the main axis of the connecting column 310 is parallel to the overall height direction (usually the vertical direction) of the packaging bag. This arrangement ensures that the hanging force can directly act on the vertical center line of the packaging bag, which helps to maintain the vertical posture of the packaging bag when hanging and reduces the inclination caused by uneven stress. For example, the connecting column 310 can be designed as a cylindrical or square column, and its length is sufficient to form a sufficient support height above the cover body 200, so that the hanging arm 311 can work effectively; or the connecting column 310 can also be a hollow tubular structure to reduce the weight while maintaining sufficient compressive and bending strength.

[0095] One end of the connecting column 310 is firmly connected with the cover body 200, ensuring reliable fixation between the hanging component 300 and the packaging bag body. It prevents the hanging component 300 from loosening or falling off during use. For example, the connecting column 310 can be fixed on the cover body 200 by threaded connection, riveting, welding or bonding, etc., depending on the material properties of the cover body 200 and the connecting column 310; or the connecting column 310 can be integrally formed with the cover body 200, for example, the base part of the connecting column 310 is directly formed when the cover body 200 is injection molded, thereby providing extremely high connection strength and stability.

[0096] The hanging site 3111 is a specific space or area formed between the hanging arm 311 and the wall surface of the cover body 200 for hooking. It can be understood as the part that actually bears the weight of the packaging bag and contacts the external hanging device (such as a drone hook), for example, it can be an open U-shaped or C-shaped slot, which is matched in size and shape with a common hook, facilitating quick hanging and taking off; or the hanging site 3111 can also be designed as a hole or a ring with certain limiting structure to provide stronger anti-falling ability after hanging, for example, by passing the hook through the hole or ring structure.

[0097] Through the above technical solutions, the hanging component 300 is designed to be composed of the connecting column 310 and the hanging arm 311, the connecting column 310 extends along the height direction and is fixedly connected to the cover body 200, which can make the hanging force act vertically on the packaging bag, providing a stable vertical support base for the entire hanging system, avoiding loosening or falling off of the hanging component 300. The hanging arm 311 extends along the vertical direction perpendicular to the height direction and is fixedly connected to the other end of the connecting column 310, forming a horizontal hanging point, which not only facilitates quick and accurate connection with the external distribution device (such as a drone hook), but also through the hanging site 3111 formed between the hanging arm 311 and the wall surface of the cover body 200, the packaging bag can maintain good balance when hanging, so that the packaging bag can effectively reduce shaking and tilting when being hung and transported, improving the stability and safety of the packaging bag during transportation.

[0098] Further, in the present application, please refer to Figure 1 and Figure 2 The projection center of the hanging site 3111 in the height direction coincides with the geometric center of the cover body 200 and the bag body 100.

[0099] Specifically, the projection center of the hanging position 3111 in the height direction refers to the projection center of the hanging point of the suspension component 300 for bearing the packaging bag on the horizontal plane, indicating the effective position of the suspension force acting on the packaging bag. The geometric center of the cover body 200 and the bag body 100 refers to the gravity center position of the entire packaging bag in the loaded state. The present application sets the hanging position 3111 to coincide with the geometric center of the cover body 200 and the bag body 100 in the height direction, so that the hanging point of the packaging bag is located at the gravity center position of the packaging bag, and the risk of tilting of the packaging bag due to gravity center deviation when hanging can be reduced.

[0100] For the hanging packaging bag provided by the present application, in some embodiments, two connecting columns 310 are provided, and the two connecting columns 310 are spaced apart at a preset distance in the vertical direction. The other end of the two connecting columns 310 is fixedly connected with the hanging arm 311, and the hanging position 3111 is located between the two connecting columns 310. In addition, the hanging arm 311 and the two connecting columns 310 are provided as an integral structure.

[0101] By adopting the above technical solution, the two connecting columns 310 are provided and spaced apart at a preset distance in the vertical direction, providing stable double-point support for the hanging arm 311, effectively dispersing the hanging load, and enhancing the torsional resistance and stability of the structure. The other end of the two connecting columns 310 is fixedly connected with the hanging arm 311, and the hanging position 3111 is located between the two connecting columns 310, further strengthening the overall rigidity of the suspension component 300 and ensuring that the suspension force can be stably transmitted. Further, the hanging arm 311 and the two connecting columns 310 are provided as an integral structure, eliminating the connecting gaps and potential weak links between components, significantly improving the structural strength and durability of the suspension component 300. Even in dynamic transportation in high-speed or complex environments such as unmanned delivery devices, the stability and balance of the packaging bag can be maintained, effectively preventing the goods from being damaged by tilting, thereby improving the delivery efficiency and user experience.

[0102] The above technical solution is further described in conjunction with the following use scenarios:

[0103] For example, an unmanned delivery device needs to deliver a hot meal from a merchant to the user's location. When the traditional packaging bag is suspended and transported by the unmanned delivery device, it is often unstable due to the center of gravity and tilts, even overflows, and the suspension operation is not convenient. To solve these problems, a new type of hanging packaging bag is used.

[0104] The hanging packaging bag provided by the present application comprises a bag body 100, which has a rectangular bottom wall 110 and surrounds a pair of first side walls 121 and a pair of second side walls 122 erected on the edges of the bottom wall 110 in the height direction. The bottom wall 110 and the side walls together enclose a containing space for holding hot food. The bag body 100 is made of non-woven fabric material, and the inner wall is stacked with a heat preservation layer to ensure that the food maintains the temperature during transportation. The bottom of the bag body 100 is also provided with a bottom reinforcing structure 130, such as a detachable plastic honeycomb plate, which is placed on the bottom of the containing space above the bottom wall 110. The elastic modulus of the material of the bottom reinforcing structure 130 is greater than that of the bottom wall 110, thereby providing additional support and stability to the bottom of the bag body 100 to prevent deformation caused by heavy pressure.

[0105] The open end of the packaging bag is covered by a cover body 200. The cover body 200 is rectangular corresponding to the open end and is made of hard plastic plate material, and the elastic modulus of the material thereof is greater than that of the bag body 100, thereby providing good structural rigidity. One side edge of the cover body 200 is reversibly connected to the top edge of one of the first side walls 121, forming a hinge point. The other edges of the cover body 200, i.e., the portions corresponding to the top edges of the other first side wall 121 and the pair of second side walls 122, are connected by a separable connecting structure 210. Such a separable connecting structure 210 does not include connecting walls 123 or adhesive components extending outward from the top edges of the side walls, but directly realizes separable connection between the edges of the cover body 200 and the top edges of the side walls, such as by magic tape or double-sided tape. When it is necessary to take out the items, the user can easily separate the remaining edges of the cover body 200 and turn the cover body 200 inward around the part connected to the first side wall 121 to the containing space, so that it is attached to the inner wall surface of the side wall, thereby completely opening the bag body 100, facilitating the taking of the items and the cover body 200 not hindering the operation. The remaining edge portions of the cover body 200 are aligned with the edges of the side walls at the open end, thereby ensuring good sealing and appearance.

[0106] On the side of the cover body 200 away from the bottom wall 110, a hanging component 300 is provided. The hanging component 300 comprises two connecting columns 310 and a hanging arm 311. The two connecting columns 310 extend in the height direction, one end of which is fixedly connected to the cover body 200 and is spaced apart at a predetermined distance in the vertical direction perpendicular to the height direction. The hanging arm 311 extends in the vertical direction and is fixedly connected to the other end of the two connecting columns 310, and a hanging position 3111 is formed between the hanging arm 311 and the wall surface of the cover body 200. The hanging arm 311 and the two connecting columns 310 are arranged in an integrated structure, thereby enhancing the strength and stability of the whole. The hanging position 3111 is located between the two connecting columns 310, and the projection center thereof in the height direction coincides with the geometric center of the cover body 200 and the bag body 100.

[0107] When the unmanned delivery device delivers, the mechanical arm can conveniently grab the hanging position 3111 of the hanging component 300. Since the hanging component 300 is designed on the cover 200, and the projection center of the hanging position 3111 in the height direction coincides with the geometric center of the bag body 100, so that the center of gravity of the whole packaging bag can be kept directly below the hanging point when hanging. The packaging bag can maintain the stability of the height when being hung and transported by the unmanned delivery device, effectively avoiding the tilting or dumping problem of the conventional packaging bag during air transportation. The unmanned delivery device can stably and efficiently complete the hanging and transportation task without manual intervention, thereby improving the delivery efficiency and the safety of the goods.

[0108] In addition, a pair of second side walls 122 of the bag body 100 are formed with first creases 124 extending in the height direction, and the bottom wall 110 is formed with second creases 111 extending in the width direction of the bag body 100 and connected with the first creases 124. When not in use, the bag body 100 can be folded into a flat shape along the first creases 124 and the second creases 111, facilitating storage and transportation.
