Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a self-heating can. Background Art

[0002] Most of the instructions for existing canned liquid foods have the words "better to eat after heating" written on them. However, existing canned liquid foods generally cannot be heated by themselves. If they need to be heated, they need to be steamed with open flames or household appliances. For this reason, people have designed self-heating cans. However, when using existing self-heating cans, water is generally added to the bottom to make the heating pack in the package react and generate heat. When using such a package, there needs to be accessible water around to react with the heating pack, which is inconvenient to use. In addition, the high-temperature gas after the reaction drifts uncontrollably, the heat utilization rate is low, the heating effect on food is poor, and consumers are easily scalded.

The water bag and the heating bag are both arranged in the storage cavity. The bottom of the tank body is provided with a water bag breaking mechanism, and the water bag is broken by the water bag breaking mechanism, so that the water in the water bag flows out and reacts with the reactant in the heating bag to generate heat, thereby heating the substance in the tank body.

[0005] Furthermore, the water-breaking bag mechanism includes a tank bottom spring piece fixedly connected to the bottom end of the tank body, a puncture ejector pin fixedly connected to the middle part of the inner side of the tank bottom spring piece, and a protective cap arranged at the end of the puncture ejector pin. The middle part of the tank bottom spring piece is raised relative to the edge, and the tank bottom spring piece is provided with a convex edge relative to the outer edge, and the height of the convex edge is not less than the protruding height when the middle part of the tank bottom spring piece is raised outward.

[0006] Furthermore, the water bag is arranged at the bottom side of the storage cavity, the heating bag is ring-shaped, a through hole is arranged in the middle, and the heating bag is sleeved on the puncture ejector pin.

[0007] The advantages of the utility model compared with the prior art are: the utility model arranges a water bag and a heating bag at the bottom of the tank body, and when in use, the water bag can be destroyed by simple operation to allow water to flow out and react with the heating bag, which is easy to use, and the high-temperature gas generated by the reaction will not float out, the heat utilization rate is high, the food heating effect is good, and consumers will not be scalded, and the safety is good.

[0012] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0013] Embodiment 1, in combination with Figure 2 The water bag breaking mechanism can also take the following form: the water bag breaking mechanism includes a tank bottom spring piece 9 fixedly connected to the bottom end of the tank body 1, a puncture ejector pin 10 fixedly connected to the middle part of the inner side of the tank bottom spring piece 9, and a protective cap 11 arranged at the end of the puncture ejector pin 10 to prevent the water bag 2 from being accidentally punctured. The middle part of the tank bottom spring piece 9 is raised relative to the edge. The middle part of the tank bottom spring piece 9 is initially raised outward. The outer edge of the tank bottom spring piece 9 is provided with a convex edge 12. The height of the convex edge 12 is not less than the protruding height when the middle part of the tank bottom spring piece 9 is raised outward, thereby preventing the tank bottom spring piece 9 from being accidentally squeezed.

[0014] The water bag 2 is arranged at the bottom side of the storage cavity, the heating bag 3 is ring-shaped and has a through hole in the middle, and the heating bag 3 is sleeved on the puncture ejector needle 10 .

[0015] When in use, turn the tank body 1 upside down and press the spring piece 9 at the bottom of the tank. The middle part of the spring piece 9 at the bottom of the tank bulges inward, thereby driving the protective cap 11 to squeeze the water bag 2 to make it rupture. The water in the water bag 2 flows out and reacts with the substance in the heating bag 3 to generate a large amount of heat. Shake the tank body 1 gently, then stand the tank body 1 upright, open the lid on the tank body 1, and wait for heating.

[0016] Embodiment 2, in combination with Figure 1 A self-heating tank comprises a tank body 1, a water bag 2, and a heating bag 3.

[0017] A partition 4 is provided at the inner bottom of the tank body 1, and a storage cavity is formed at the bottom of the tank body 1 through the partition 4. The water bag 2 and the heating bag 3 are both arranged in the storage cavity. A water bag breaking mechanism is provided at the bottom of the tank body 1, and the water bag 2 is broken by the water bag breaking mechanism, so that the water in the water bag 2 flows out and reacts with the reactant in the heating bag 3 to generate heat, thereby heating the material in the tank body 1.

[0018] The water-breaking bag mechanism includes a connecting tube 5, a gripping portion 6 fixedly connected to one end of the connecting tube 5, and the other end of the connecting tube 5 is evenly provided with puncture teeth 7 along the circumference. The inner wall of the storage cavity is provided with an internal thread, and the outer wall of the connecting tube 5 is provided with an external thread. The connecting tube 5 is threadedly and sealedly connected to the tank body 1, and an opening pull strip 8 is provided between the gripping portion 6 and the bottom end of the tank body 1.

[0019] The water bag 2 is arranged at the bottom side of the storage chamber, and the heating bag 3 is arranged inside the connecting pipe 5 .

[0020] When in use, tear off the opening strip 8, rotate the grip 6, move the connecting tube 5 into the storage chamber, thereby driving the puncture teeth 7 to move and puncture the water bag 2. The water in the water bag 2 flows out and reacts with the substance in the heating bag 3 to generate a large amount of heat. Gently shake the tank body 1, open the lid of the tank body 1 and wait for heating.
