Description

Technical Field

[0001] The utility model relates to the technical field of takeaway bags, and specifically relates to a heat preservation bag for takeaway packaging with a limiting structure. Background Technique

[0002] Takeaway refers to the sale of goods for customers to take away from the store. With the popularization of telephones, mobile phones, and the Internet, the takeaway industry has developed rapidly. Takeaway is a very broad term. In the past, it was understood as the delivery service of fast food. However, with the formation and popularization of the convenient and fast "takeaway lifestyle" of "immediate need, immediate takeaway, immediate use" by the majority of users, now all the delivery goods provided by sellers can be said to be takeaways. Such as flowers, mobile phones, cosmetics, pet food, and toys, these can all be bought through takeaways. It can be said that "everything can be taken away". During the takeaway process of takeaway food, it needs to be packaged, so a heat preservation bag for takeaway packaging is required.

[0003] A Chinese patent with the authorization publication number CN212830103U discloses a takeaway bag, which relates to the packaging field and includes a bag body. The upper end of the bag body has a first opening that can be opened and closed, and the first opening is irreversible after being closed. A second opening is provided on the side wall of the bag body, and a tearing strip is provided on the second opening. By tearing off the tearing strip, the second opening is in an open state, where Figure 1 shows the state where the first opening of the bag body is not closed, Figure 2 shows the state where the first opening is closed after the food is put into the bag body. The first opening provided on the bag body is used to put the food to be delivered into the bag body, and then the first opening is closed. The first opening is irreversible after being closed. Therefore, if the first opening is opened again, the entire bag body needs to be damaged. When the food in the bag body needs to be taken out, the tearing strip on the second opening is torn off, and the food in the bag body can be taken out.

[0004] Although the above takeaway bag avoids the problem that the meal will be opened during the delivery process, resulting in the safety of the meal not being guaranteed, the internal structure of the takeaway packaging bag is simple, and usually only the simple effect of packaging and heat preservation can be achieved. For some soup-containing foods in the meal, during the takeaway process, it is easy to cause the food to spill due to bumps, etc., affecting the user's consumption. Therefore, we propose a heat preservation bag for takeaway packaging with a limiting structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat preservation bag for takeaway packaging with a limiting structure to solve the problem proposed in the above background technique that due to the simple internal structure of the takeaway packaging bag, usually only the simple effect of packaging and heat preservation can be achieved, and for some soup-containing foods in the meal, during the takeaway process, it is easy to cause the food to spill due to bumps, etc., affecting the user's consumption.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A heat-insulating bag for takeout packaging with a limiting structure, comprising:

[0007] A packaging bag body, one end above the packaging bag body is connected with a sealing cover, and heat-insulating layers are provided on the inner walls of both the sealing cover and the packaging bag body. On both sides above the packaging bag body, carrying straps are provided, and a magic tape is provided at the connection between the carrying strap and the packaging bag body;

[0008] A bottom plate, which is installed at the bottom inside the packaging bag body. On both sides above the bottom plate, limiting plates are installed, and a telescopic connecting plate is connected to the middle of the limiting plate. Telescopic springs are connected to both sides of the telescopic connecting plate, and a limiting sliding groove is provided at the connection between the limiting plate and the packaging bag body;

[0009] A sealing strip, which is provided on the sealing strip, and a release paper is connected to one end of the sealing strip.

[0010] Preferably, the heat-insulating layer is closely attached to the packaging bag body, and the size of the bottom plate matches that of the packaging bag body.

[0011] Preferably, the limiting plate is in an L-shaped structure, and the limiting plates are symmetrically distributed about the vertical center line of the bottom plate.

[0012] Preferably, an elastic telescopic structure is formed between the telescopic connecting plate and the limiting plate through the telescopic spring, and the limiting plate is slidably connected to the packaging bag body through the limiting sliding groove.

[0013] Preferably, the sealing cover is adhesively connected to the packaging bag body through the magic tape, the carrying straps are symmetrically distributed about the vertical center line of the packaging bag body, and the release paper is adhesively connected to the sealing strip.

[0014] Preferably, the packaging bag body is further provided with:

[0015] A tableware bag, which is installed at one end outside the packaging bag body. A cover body is provided above the tableware bag, and a sticking buckle is provided at the connection between the cover body and the tableware bag.

[0016] Compared with the prior art, the present utility model provides a heat-insulating bag for takeout packaging with a limiting structure, and has the following beneficial effects:

[0017] With the limiting plate of the L-shaped structure under the action of the telescopic spring, the utility model can stretch with the telescopic connecting plate, so that the relative position of the limiting plate can be adjusted according to the size of the packing box. At the same time, the limiting plate can clamp and limit the packing box to prevent the packing box from tilting in the packaging bag and causing the soup to spill out. It avoids the problem that the structure inside the takeaway packaging bag is simple and usually can only achieve the simple effect of heat preservation. Among the meals, there are some soup-containing foods, which are prone to spillage during the takeaway process due to bumps and other reasons, affecting the user's consumption.
