Abstract
Description
Technical Field
[0001] This utility model relates to the field of food packaging can technology, and in particular to a modular food packaging can. Background Technology
[0002] Self-heating food packaging containers are portable containers that can heat food through built-in chemical reactions or physical mechanisms without the need for external heat sources such as open flames or electricity. Their core feature is that they achieve rapid heating of food through the autonomous heat generation of internal components, making them particularly suitable for outdoor, emergency, or fast-paced lifestyle scenarios.
[0003] A typical self-heating food packaging can includes an outer packaging layer, an inner container, and a heating pack. However, existing self-heating food packaging cans are usually disposable and not convenient to reuse. To reduce resource consumption, a modular food packaging can is proposed that supports the reuse of the can body. It can be recycled by only replacing consumables. It is suitable for quickly replenishing hot food during mountaineering and camping or for emergency hot food supply during disasters such as earthquakes and floods. The bottom is designed with a finned structure to prevent users from being burned by residual heat when lifting from the bottom. Utility Model Content
[0004] This utility model provides a modular food packaging can that solves the problems mentioned in the background. It supports the reuse of the can body and can be recycled by replacing only the consumables. It is suitable for quickly replenishing hot food during mountaineering and camping or for emergency relief hot food supply during disasters such as earthquakes and floods. The bottom is designed with a finned structure to prevent users from being scalded by residual heat when holding it from the bottom.
[0005] The present invention provides the following solution to the above-mentioned technical problems: A combined food packaging can includes a can lid, a food heating can, an inner bowl, a heating base, and a heating pack. The can lid is provided with an ear groove, and the food heating can is provided with a steam exhaust hole corresponding to the ear groove. The inner bowl is placed inside the food heating can, the food heating can is snapped into the heating base, the heating pack is placed inside the heating base, and the heating base is equipped with anti-scalding fins.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, there are two ear slots, symmetrically arranged on both sides of the lid, and two steam exhaust holes corresponding to the ear slots. Steam generated by heating food in the inner bowl can be discharged through the steam exhaust holes and ear slots.
[0008] Furthermore, the food heating tank is provided with a first locking strip, and the can lid has a first locking slot corresponding to the first locking strip. The first locking strip of the food heating tank can be inserted into the first locking slot of the can lid for temporary positioning.
[0009] Furthermore, the food heating tank is evenly provided with heating holes, through which heating steam can pass to heat the inner bowl and the food it contains.
[0010] Furthermore, the food heating tank is fixedly installed with a positioning ring, which is adapted to the diameter of the inner bowl's edge, so that the inner bowl can be stably placed inside the food heating tank.
[0011] Furthermore, the food heating tank is evenly provided with second-order locking strips, and the heating base is provided with a second-order locking slot corresponding to the second-order locking strips. The second-order locking slots are inclined, and the food heating tank can rotate counterclockwise to engage with the heating base.
[0012] Furthermore, the heating base has a placement slot corresponding to the heating pack, so that the heating pack can be stably placed in the heating base.
[0013] Furthermore, the food heating container is affixed with a label strip to facilitate operation by first-time users.
[0014] Furthermore, the label includes icons for "Rotate the bowl one full turn to the left" and "Do not tip over for heating".
[0015] Furthermore, the anti-scalding fins are arranged in a ring at the bottom of the heating base. The anti-scalding fins are made of PPSU engineering plastic, which has a temperature resistance of over ℃, low thermal conductivity, and food-grade certification.
[0016] This utility model provides a modular food packaging can, which has the following advantages:
[0017] 1. Place the heating pack in the placement slot of the heating base, add water, and then rotate and snap the food heating container to the heating base. Place the food in the inner bowl, and then place the inner bowl in the food heating container. The positioning ring can support and limit the inner bowl. Seal the lid on the top of the food heating container and wait for heating. This modular food packaging container structure is easy to operate and use, and can be reused by simply replacing the heating pack.
[0018] 2. The magnesium-iron alloy heating pack can heat up quickly in four to five minutes. Steam can be used to heat the inner bowl of the food heating can through the heating hole, so that the food in the inner bowl can be heated stably. The steam generated by the food in the inner bowl can be discharged from the ear groove through the steam exhaust hole, so that the food can be heated quickly and is convenient for outdoor use.
[0019] 3. Once the steam stops escaping and the container has cooled down, open the lid and wait for the inner bowl to cool before removing and enjoying the food. The heating base has anti-scalding fins at the bottom to prevent users from being burned by the residual heat of the heating base, making it easier for users to hold and use the heating base, thus making the use process safer.
[0020] 4. This type of modular food packaging can supports the reuse of the can body. It can be recycled by only replacing consumables. It is suitable for quickly replenishing hot food during mountaineering and camping or for emergency hot food supply during disasters such as earthquakes and floods. The bottom is designed with a finned structure to prevent users from being burned by residual heat when lifting from the bottom.
