Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a heat-insulating packaging bag. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation of articles during the production and circulation process and is easy to store. It is widely used in daily life and industrial production. The heat-insulating packaging bag is widely used in the takeaway industry. When the existing packaging bags are in use, most of them are made of paper materials. The packaging bags are prone to collapse and soften. When packaging and transporting liquid foods such as soups and porridges, the inner packaging box is prone to skew, causing the soup to spill, affecting the customer's purchase experience. Moreover, the heat-insulating effect of the paper packaging bag is poor, and the heat of the food is lost quickly, affecting the taste of the food during takeaway delivery. Therefore, a heat-insulating packaging bag is needed.

[0003] When an existing packaging bag is in operation, it has problems such as poor heat-insulating effect, easy collapse and softening of the packaging bag, affecting the appearance, and inability to prevent the internal food soup from spilling. Therefore, a heat-insulating packaging bag is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a heat-insulating packaging bag to solve the problems of poor heat-insulating effect, easy collapse and softening of the existing packaging bag, affecting the appearance, and inability to prevent the internal food soup from spilling when in use.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-insulating packaging bag includes a packaging bag body. A rib is installed on the inner wall of the packaging bag body. A connecting ring is installed on the top of the rib. A sealing cover plate is installed on the inner wall of the connecting ring.

[0006] A limiting mechanism is installed on the inner wall of the packaging bag body.

[0007] A clamping seat is installed on the bottom inner wall of the packaging bag body. A heat-insulating sleeve is installed on the outer wall of the packaging bag body. A heating strip is installed on the inner wall of the heat-insulating sleeve. A power port is opened on the outer side wall of the heat-insulating sleeve. A handle is installed on the outer wall of the packaging bag body.

[0008] Preferably, the ribs are arranged in a circular array centered on the central axis of the packaging bag body, and the connecting ring is threadedly connected with the sealing cover plate.

[0009] Preferably, the limiting mechanism includes a fixed sleeve, a limiting rod, a limiting spring and a clamping plate. A fixed sleeve is installed on the inner wall of the packaging bag body. A limiting rod is installed on the inner wall of the fixed sleeve. A limiting spring is installed on the outer wall of the limiting rod. A clamping plate is installed on the outer wall of the limiting rod.

[0010] Preferably, the fixing sleeve is snap-fitted with the limiting rod, and the clamping plate and the fixing sleeve form a telescopic structure through a limiting spring.

[0011] Preferably, the heat preservation sleeve is made of non-woven heat preservation cotton, and the heating strip is inserted into the heat preservation sleeve.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the rib strips provided in the present utility model, most of the existing food outer packages are made of paper materials. During the packaging and transportation process, the outer packages are prone to wrinkles and collapse, affecting the overall aesthetics and thus the sales volume. However, the main body of the packaging bag of the present utility model is made of a composite material of pearl cotton, and rib strips are sewn inside it. The rib strips can support the main body of the packaging bag, making it non-deformable and more durable.

[0014] 2. Through the limiting mechanism provided in the present utility model, the food to be transported is placed into the main body of the packaging bag, and the clamping plate is pressed inward by the elastic force of the limiting spring to clamp and fix the food to be transported. Moreover, the clamping seat is made of plastic material, which plays a role in supporting and snap-fixing at the bottom of the main body of the packaging bag, thereby increasing the stability of the food to be transported stored inside the main body of the packaging bag and preventing the food from tipping over and causing the soup to spill.

[0015] 3. Through the heat preservation sleeve, heating strip and power supply port provided in the present utility model, after the food to be transported is placed inside the main body of the packaging bag, the heating strip is inserted into the heat preservation sleeve and powered on through the power supply port, so that the heating strip heats up to keep the food inside the main body of the packaging bag warm, preventing the heat of the food from being lost and improving the edible taste of the food when it is delivered to the target location.
