The utility model sets a connecting plate to cooperate with the connecting belt and the support frame, and then limits the ice bag by inserting the card plate into the card slot, and improves the stability of the ice bag during movement by increasing the contact area, and then the connecting plates can be connected by inserting the spring ejector into the through hole on the connecting plate, so as to further increase the contact area and prevent the ice bag from colliding and leaking.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the above-mentioned device prevents collisions between ice bags by means of spring buffering, thereby achieving a leak-proof protection effect for the ice bags. In actual use, the risk of ice bags being damaged due to impact is not high. Most ice bags are usually ruptured by sharp objects piercing the surface of the ice bags during actual use, thereby causing water leakage. The above-mentioned device has no protective effect against puncture damage. Utility Model Content

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] Example: See Figure 1-4 , the utility model provides a technical solution: an anti-puncture ice bag comprises an outer wrapping layer 1, the outer wrapping layer 1 is connected to a water inlet connector 3, the top of the water inlet connector 3 is connected to a water inlet connector 4, which is used to inject water into the ice bag;

[0024] Furthermore, the outer end surface of the outer wrapping layer 1 is provided with a plurality of anti-slip grooves 2 distributed at equal intervals, the top of the water inlet joint 4 is provided with a sealing member, the top side of the water inlet joint 4 is provided with a limiting groove, the sealing member is provided with a limiting buckle, and the limiting buckle is connected to the limiting groove. The outer wrapping layer 1 is made of pp plastic, which is a food-grade plastic. Therefore, when the ice bag is used, the outer wrapping layer 1 can directly contact the food.

[0025] The water inlet connector 3 is hollow inside, and a waterproof liner 5 is connected to the inner wall of the water inlet connector 3, and an inner wrapping layer 9 is connected to the outer wall of the waterproof liner 5. A sealing interlayer 7 is connected to the side of the inner wrapping layer 9 away from the waterproof liner 5, and a plurality of equally spaced inner extrusion parts 8 are connected to the side of the sealing interlayer 7 facing the outer wrapping layer 1. A plurality of equally spaced outer extrusion parts 6 are provided on the side of the outer wrapping layer 1 facing the sealing interlayer 7, and the outer extrusion parts 6 are in contact with the inner extrusion parts 8. The waterproof liner 5 is made of rubber. The waterproof liner 5 made of rubber can prevent water leakage inside the ice bag, and in a low temperature environment, the hardness of the rubber will increase due to its characteristics, thereby increasing the difficulty of the ice bag being punctured.

[0026] The inner wrapping layer 9 is hollow inside and is located between the waterproof liner 5 and the sealing interlayer 7. The inner wrapping layer 9 is made of pp plastic material. As a food-grade plastic material, in the event of an accidental water leak in the ice bag, the water will not carry toxicity when passing through the pp plastic, thereby ensuring that even if the ice bag leaks, it will not contaminate food items. The sealing interlayer 7 is made of latex material;

[0027] Furthermore, a water-absorbing resin is provided inside the inner wrapping layer 9. When the ice bag is punctured, the water-absorbing resin can absorb the water seeping out from the hole. After absorbing a certain amount of water, the water-absorbing resin will expand, thereby increasing the volume of the inner wrapping layer 9. As the volume of the inner wrapping layer 9 increases, the sealing interlayer 7 is squeezed. At the same time, the expanded water-absorbing resin will reduce the gap between the holes, thereby reducing the speed of water seepage.

[0028] The inner extrusion component 8 is obliquely arranged on the side of the sealing interlayer 7, and the outer extrusion component 6 is obliquely arranged on the side of the outer wrapping layer 1. The inner extrusion component 8 and the outer extrusion component 6 are provided with waterproof layers on their sides. The waterproof layer is made of epoxy resin. When puncture and damage occur, when the water-absorbing resin expands, the volume of the inner wrapping layer 9 increases to squeeze the sealing interlayer 7. After the sealing interlayer 7 is squeezed, the gap between the sealing interlayer 7 and the outer wrapping layer 1 becomes smaller. Since the outer extrusion component 6 and the inner extrusion component 8 are obliquely arranged between the sealing interlayer 7 and the outer wrapping layer 1, after the sealing interlayer 7 is squeezed, the inclined surfaces of the outer extrusion component 6 and the inner extrusion component 8 abut against and fit each other, so that the epoxy resin waterproof surfaces are in contact and squeezed with each other, thereby improving the sealing effect between the sealing interlayer 7 and the outer wrapping layer 1. The sealing interlayer 7 made of latex can ensure that the sealing interlayer 7 is still flexible in a low temperature environment. Therefore, when the inner wrapping layer 9 expands, the sealing interlayer 7 can be ensured to be deformed.

[0029] The water inlet connector 3 is bucket-shaped, and a sealing ring is provided on the top of the water inlet connector 3 . The sealing ring is arranged at the connection seam between the water inlet connector 3 and the water inlet joint 4 .

[0030] The combination of the sealing interlayer 7 and the inner wrapping layer 9 can realize the puncture-proof and damage-proof properties of the present application, and can also achieve a self-repairing effect to a certain extent.

[0031] When the ice bag is in use, water can be poured into the ice bag from the top by opening the seal at the top of the water inlet connector 4, thereby making it easier to add water to the ice bag for use. After the filling is completed, the seal and the water inlet connector are sealed and blocked, thereby reducing the risk of water leakage in the ice bag.

[0032] After the ice bag is frozen, the water inside freezes, so that the application has a continuous cooling effect.

[0033] When the ice bag is punctured, the hole caused by the puncture penetrates the sealing interlayer 7 and the inner wrapping layer 9. After the puncture occurs, the moisture inside the waterproof liner 5 flows out along the hole caused by the puncture. When the water flows from the waterproof liner 5 to the inner wrapping layer 9, the water comes into contact with the water-absorbing resin inside the inner wrapping layer 9. The water-absorbing resin has water-absorbing properties, thereby absorbing the water that seeps outward, and in the process of the water-absorbing resin absorbing water, as the amount of water absorbed increases, the volume of the water-absorbing resin will expand, and the expanded water-absorbing resin will fill the holes caused by the puncture, thereby reducing the size of the leakage holes and reducing the leakage rate of the ice bag.

[0034] After the water-absorbing resin in the inner wrapping layer 9 expands, the inner wrapping layer 9 squeezes the sealing interlayer 7, which leads to a decrease in the gap between the sealing interlayer 7 and the outer wrapping layer 1. When the sealing interlayer 7 is squeezed, the outer extrusion piece 6 and the inner extrusion piece 8 between the sealing interlayer 7 and the outer wrapping layer 1 squeeze each other to a greater extent, thereby improving the sealing between the sealing interlayer 7 and the outer wrapping layer 1 and further reducing the speed at which the water inside the ice bag flows out.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
