[0027] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0028] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should be the common meanings understood by technical personnel in the field to which this application belongs. The data involved in this application (including but not limited to data used for model training, stored data, displayed data, etc.) are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0029] First, some nouns or terms appearing in the embodiments of the present application may be explained as follows:

[0030] Cold storage bag: a bag that can be used to hold items at temperatures between -20°C and 50°C.

[0031] Sealing strip: A snap-on seal at the bag opening.

[0032] Sliding cover: When sealing with a sealing strip, it is used to keep the opening of the bag rolled into a U-shaped structure to prevent liquid leakage from the bag.

[0033] In the related art, there are some container devices that can be used to hold liquids, such as outdoor portable water bags, which can be used to hold drinking water and can be reused, with a low overall cost. In view of the fact that store merchants can provide ice cubes (cold storage source) to delivery personnel when they take cold drinks, the above-mentioned reusable outdoor portable water bags can also be used as cold storage bags. After ice cubes are put into the cold storage bags, the cold drinks or food can be kept warm (kept at a low temperature) during the cold drink delivery process by the delivery personnel. Based on the ice cubes provided by each store merchant, the delivery needs of the delivery personnel for one day can be met, and at the same time it has the advantage of low cost. However, this type of cold storage bag has the problem of uneven surface, which can easily cause the cold drinks to tip over when used for cold drink delivery.

[0034] In order to solve the above problems, the embodiment of the present application proposes a packaging bag for cold storage and an insulation box containing the packaging bag for cold storage. The packaging bag for cold storage includes a flexible cold storage bag. Since the flexible cold storage bag may be partially bulged after a cold storage source such as ice cubes is loaded into the flexible cold storage bag, resulting in an uneven surface of the cold storage bag, the embodiment also provides a rigid flat plate on the outer wall of the cold storage bag. Since the flat plate is rigid, even if the cold storage bag is partially bulged, the flat plate can remain flat. Based on this, the packaging bag for cold storage can be used in the storage and transportation process of cold drinks or cold food. For example, during the delivery process of cold drinks or cold food in summer, the takeaway delivery personnel can place the cold drinks or cold food on the rigid flat plate, and the cold drinks or cold food on the flat plate can be cooled and stored. Based on the flatness of the flat plate, the cold drinks or cold food can also be prevented from being dumped and spilled. In addition, the cold storage bag can be reused. In the case of repeated replacement of the cold storage source, it can be used for a long time in the storage and transportation process of cold drinks or cold food, and the cost is low.

[0035] The various technical solutions provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0036] See also Figure 1 , is a schematic diagram of the exploded structure of the cold storage packaging bag provided in the embodiment of the present application, such as Figure 1 As shown, the cold storage packaging bag may include a flexible bag body 10 and a rigid flat plate 20, wherein the flexible bag body 10 is provided with an opening, and the opening is provided with a sealing structure (the sealing structure and the opening are Figure 1 The rigid plate 20 is disposed on the outer wall of the flexible bag body 10 , and the panel direction of the rigid plate 20 is parallel to the first plane formed by the length direction and the width direction of the flexible bag body 10 .

[0037] The flexible bag 10 may be made of, but not limited to, soft films such as TPU (Thermoplastic polyurethanes), PE (Polyethylene) or PVC (Polyvinyl chloride) to accommodate cold storage sources of different shapes. The rigid plate 20 may be, but not limited to, a plastic plate or a light metal plate, as long as the plate has a certain degree of rigidity and thermal conductivity.

[0038] The flexible bag body 10 may be, but is not limited to, flat or square, and may be integrally formed or may be formed by connecting multiple pieces of film cloth. For example, it may include a first portion and a second portion ( Figure 1 Not shown in the figure, it can be understood as Figure 1 The first part and the second part are connected at the edges to form a flat bag body 10, and the rigid panel is arranged on the first part or the second part, wherein the first part and the second part can be membrane cloths composed of soft films such as TPU, PE or PVC mentioned above.

[0039] As described above, the flexible bag body 10 may be integrally formed, or may include a first portion and a second portion disposed opposite to each other, or may be formed as follows. Figure 1 As shown, between the first part and the second part, a side connecting part is provided along the edges of the first part and the second part to increase the internal space of the flexible bag body 10 .

[0040] The panel direction of the rigid flat panel 20 is parallel to the first plane formed by the length direction and the width direction of the flexible bag body 10. The size of the rigid flat panel 20 can be equivalent to the projection area of ​​the flexible bag body 10 on the first plane, so as to cover the flexible bag body 10. The specific shape of the rigid flat panel 20 can also be the same as the projection shape of the flexible bag body 10 on the first plane, or slightly different. For example, if the shape of the flexible bag body 10 is as follows: Figure 2 In the shown closed type, the projection size of the opening is smaller than the projection line size of other parts of the bag body 10 in the width direction, and the rigid flat plate 20 can also be set so that the size of one end in the width direction is smaller than the size of other parts in the width direction, or it can be directly set as a square plate according to the overall width.

[0041] It is understandable that the size of the rigid plate 20 may be comparable to the projection area of ​​the flexible bag body 10 on the first plane, but may not be completely comparable, including being slightly larger or slightly smaller than the projection area of ​​the flexible bag body 10 on the first plane, and this embodiment does not specifically limit this.

[0042] The opening on the bag body 10 can be used to place a cold storage source (such as ice cubes). However, cold storage sources such as ice cubes will melt to a certain extent after long-term use, so a sealing structure is provided at the opening to prevent the melted liquid from flowing out.

[0043] The cold storage packaging bag provided in this embodiment comprises a flexible bag body 10 and a rigid flat plate 20. The flexible bag body 10 can be used to contain a cold storage source to achieve its cold storage function. The flexible bag body 10 is provided with an opening, and the cold storage source can be repeatedly put in and taken out, so that it can be reused, thereby reducing the use cost of the cold storage packaging bag. The opening is also equipped with a sealing structure to prevent the liquid in the bag body 10 from flowing out. The rigid flat plate 20 arranged on the outer wall of the flexible bag body 10 can be used to place cold drinks and / or cold food and cool them. Based on the flatness of the rigid flat plate 20, it can prevent the cold drinks and / or cold food from spilling, etc.

[0044] In some embodiments, the flexible bag body 10 may be provided with a partition structure, and the partition structure may divide the internal space of the flexible bag body 10 into a plurality of sub-spaces. In this way, the cold storage sources such as ice cubes in the cold storage bag may be placed separately, and during the delivery process of the delivery personnel delivering the order, it is possible to prevent the ice cubes from moving and aggregating, causing the ice cubes in a certain area to increase, causing the bag body 10 to bulge locally, and even affecting the balance of the rigid plate 20, causing the cold drinks or cold food to fall over.

[0045] Specifically, if the flexible bag body 10 includes the first part and the second part which are arranged opposite to each other, the rigid plate 20 can be connected to the first part, and the rigid plate 20 can be connected to the first part. Figure 3 As shown in the figure, in the middle area, the first part and the second part are point-connected, and the point-connected portion can form the above-mentioned partition structure. In this way, there is no need to add additional parts, and the membrane cloth constituting the flexible bag body 10 can be directly connected to form a partition structure, thereby further reducing the manufacturing cost.

[0046] Furthermore, the first part and the second part can be point-connected by high-frequency wave welding, which can not only connect the first part and the second part relatively firmly, but also reduce the risk of damage to the bag body 10. The high-frequency wave welding process can be, but is not limited to, high-frequency welding, ultrasonic welding, etc.

[0047] It should be noted that the point connection between the first part and the second part is only one implementation of this embodiment, and this embodiment does not specifically limit this. For example, the first part and the second part can also be connected by lines, as long as the first part and the second part are connected at the middle position to divide the internal space of the bag body 10 into multiple spaces. And this embodiment does not specifically limit the number of positions where the first part and the second part are connected by points, such as Figure 3One column and three point connection positions are shown in the figure. In this embodiment, more or fewer point connection positions may be set. For example, only one point connection position or multiple columns of point connection positions may be set.

[0048] In other embodiments, Figure 4 As shown, the opening can be provided at one end of the flexible bag body 10, and the sealing structure can include a sealing strip 11 provided at the opening, and a sliding cover 31 matched with the sealing strip 11. Thus, by providing the opening at one end of the bag body 10, the size of the opening can be increased, making it easier to take and put ice cubes. By providing the sealing strip 11 and the matching sliding cover 31, the opening of the bag body 10 can be rolled into a U-shape and slid into the sliding cover 31 to avoid leakage at the opening.

[0049] In other embodiments, Figure 5 As shown, the opening can be arranged in the middle of the flexible bag body 10, and the sealing structure includes an external thread 12 arranged at the opening and a sealing cover 32 for sealing the opening, and the sealing cover 32 is provided with an internal thread matching the external thread 12. In this way, the sealing of the opening of the bag body 10 can be achieved through thread matching.

[0050] Specifically, the opening can be arranged on the side of the bag body 10 away from the rigid plate 20, so as to facilitate the arrangement of the rigid plate 20 and the access to the cold storage source. The opening can be a circular opening, and the sealing cover 32 can also be a circular sealing cover 32, as long as the opening and the sealing cover 32 are matched.

[0051] Furthermore, an elastic sealing member may be provided in the internal thread of the sealing cover 32 to increase the contact area between the sealing cover 32 and the external thread 12 on the opening, thereby enhancing the sealing effect.

[0052] It is understandable that the middle of the flexible bag body 10 in this embodiment is not only the middle position of the flexible bag body 10, but can be understood as a position other than the end. And the sealing structure in this embodiment is not limited to the above two types, as long as the bag body 10 opening can be sealed.

[0053] In other embodiments, the rigid plate 20 and the flexible bag body 10 may be connected at points, which can reduce the restraining effect of the rigid plate 20 on the flexible bag body 10 and make it easier to take out and put away the cold storage source.

[0054] Specifically, one or more point connection positions between the rigid plate 20 and the flexible bag body 10 can be set in the middle area of ​​the flexible bag body 10 to reduce processing costs. Multiple point connection positions can also be set at intervals in the peripheral area of ​​the flexible bag body 10, which is more conducive to the stability of the rigid plate 20. Several point connection positions can also be set in the middle area and the peripheral area respectively to further enhance the stability and firmness of the rigid plate 20.

[0055] It should be noted that the point connection positions between the first part and the second part of the flexible bag body 10 are generally different from the point connection positions between the rigid plate 20 and the flexible bag body 10 to avoid multiple welding affecting the sealing of the bag body 10.

[0056] Furthermore, a high-frequency wave welding process can also be used to connect the rigid plate 20 and the flexible bag body 10 at points, which can not only connect the rigid plate 20 and the flexible bag body 10 relatively firmly, but also reduce the risk of damage to the bag body 10. The high-frequency wave welding process here can also be, but is not limited to, high-frequency welding, ultrasonic welding, etc.

[0057] Some embodiments of the present application also provide a heat preservation box, which includes a box body and a cold storage packaging bag arranged at the bottom of the box body, and the cold storage packaging bag can be a cold storage packaging bag of any of the above embodiments. The bag body 10 of the cold storage packaging bag is attached to the bottom of the box body, and the rigid flat plate 20 of the cold storage packaging bag is arranged on the outer wall of the flexible bag body 10 away from the bottom of the box body.

[0058] In practical applications, the bottom shape of the bag body 10 when laid flat and the area it occupies can be set to be comparable to the shape and size of the bottom of the box body, so as to maximize the cooling effect of the cold storage packaging bag.

[0059] It can be understood that the thermal insulation box provided in this embodiment and the cold storage packaging bag provided in the embodiment of the present application are based on the same inventive concept, and have at least the same beneficial effects as the cold storage packaging bag, and the various implementation methods of the cold storage packaging bag embodiment are also applicable to the embodiment of the thermal insulation box.
