Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a canned food with a heating function. Background Technology

[0002] Canned foods are easy to store and convenient to eat, so people often carry them as a food reserve for outdoor activities such as camping, hiking, and fieldwork. However, in these scenarios, there is a lack of conventional heating equipment such as stoves and microwave ovens, and no suitable heating methods. Consumers can only eat canned foods at room temperature or even cold. For some canned foods that need to be eaten hot to fully bring out their flavor, such as braised meat or hot soup, eating them cold not only tastes bad but may also affect digestion, reducing the enjoyment of consumers in enjoying food outdoors. Utility Model Content

[0003] The purpose of this invention is to provide a canned food with a heating function, which has the advantage of making it convenient for people to heat the food inside the can.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a canned food with a heating function, comprising:

[0005] An outer tank has a metal support bar fixedly connected to the bottom of its inner cavity. A heating pack is placed between the lower end of the metal support bar and the bottom of the inner cavity of the outer tank. Air vents are provided around the top of the outer tank, and an opening for receiving is provided at the middle of the top of the outer tank.

[0006] A bottom cover is placed on top of a metal support bar. The bottom of the bottom cover has a groove. An inner tank is fixedly connected to the top of the bottom cover around its perimeter. A can lid is fixedly connected to the top of the inner tank around its perimeter.

[0007] As a preferred embodiment, the top of the can lid is fitted with a plastic cap, and the outer surface of the plastic cap is wrapped with a plastic sealing film between the outer surface of the outer can body.

[0008] As a preferred embodiment, the surface of the receiving opening is fixedly connected with an annular protrusion, and the surface of the annular protrusion contacts the outer surface of the inner tank.

[0009] As a preferred embodiment, the number of metal support bars is four, and the distance between any two adjacent metal support bars is equal.

[0010] As a preferred embodiment, an instruction label is affixed to the front surface of the outer tank, and a water level mark is fixedly connected to the upper end of the inner cavity of the outer tank.

[0011] As a preferred embodiment, a pull ring is fixedly connected to the right end of the top of the can lid.

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

[0013] This invention, through the design of an internal tank, a bottom cover, and a lid, allows for the storage of canned food. Simultaneously, the inclusion of an opening, an external tank, a heating pack, and metal support bars provides support for the internal tank and bottom cover. When water is added to the external tank, the heating pack releases heat into the water through a chemical reaction, which is then conducted to the food through the internal tank and bottom cover, effectively heating the canned food. This design greatly satisfies the needs of people carrying the food while traveling. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The external tank 1, instruction label 2, vent 3, plastic sealing film 4, internal tank 5, plastic lid 6, heating pack 7, receiving opening 8, annular protrusion 9, tank lid 10, water level mark 11, bottom cover 12, groove 13, metal support bar 14, and pull ring 15 of this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this utility model provides a canned food with a heating function, comprising:

[0024] An outer tank 1 has a metal support bar 14 fixedly connected to the bottom of its inner cavity. A heating pack 7 is placed between the lower end of the metal support bar 14 and the bottom of the inner cavity of the outer tank 1. Air vents 3 are provided around the top of the outer tank 1, and an opening 8 is provided at the middle of the top of the outer tank 1.

[0025] A bottom cover 12 is placed on top of the metal support bar 14. A groove 13 is provided at the bottom of the bottom cover 12. An inner tank 5 is fixedly connected to the top of the bottom cover 12. A can lid 10 is fixedly connected to the top of the inner tank 5.

[0026] In this technical solution, when it is necessary to heat the canned food contained between the inner tank 5, the bottom cover 12, and the can lid 10, the inner tank 5 is removed from the outer tank 1, water is added to the outer tank 1 through the receiving opening 8, and the inner tank 5 is placed in the outer tank 1. The metal support bar 14 supports the bottom of the bottom cover 12 and limits the four corners of the heating pack 7, allowing the heating pack 7 to be positioned below the bottom cover 12 and immersed in the water. This releases a large amount of heat into the water, causing the water temperature to rise rapidly. The heat is then conducted through the inner tank 5 and the bottom cover 12 to the food inside, thus heating the canned food. Furthermore, the groove 13 effectively increases the contact area between the bottom cover 12 and the water, further improving the heating effect.

[0027] It should be noted that the heating pack 7, as an existing technology, mainly achieves its heating function by releasing heat through a chemical reaction. Its core principle is to use active substances such as quicklime, iron powder, magnesium powder, and aluminum powder to react with water and generate a large amount of heat.

[0028] Example 2:

[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a plastic cover 6 is fitted on the top of the can lid 10. A plastic sealing film 4 is wrapped between the outer surface of the plastic cover 6 and the outer surface of the outer can 1. An annular protrusion 9 is fixedly connected to the surface of the opening 8. The surface of the annular protrusion 9 contacts the outer surface of the inner can 5. There are four metal support bars 14, and the distance between two adjacent metal support bars 14 is equal. An instruction label 2 is pasted on the front surface of the outer can 1. A water level mark 11 is fixedly connected to the upper end of the inner cavity of the outer can 1. A pull ring 15 is fixedly connected to the right end of the top of the can lid 10.

[0030] In this technical solution, the plastic cover 6 is designed to protect the upper part of the can after the lid 10 is opened, preventing dust from entering the inner can 5 during the opening and placement process. The plastic sealing film 4 protects the overall surrounding area. The annular protrusion 9 effectively improves the contact between the inner can 5 and the receiving opening 8, reducing the chance of the inner can 5 shaking. The instruction label 2 explains the heating steps to facilitate accurate operation. The water level mark 11 marks the required water level, making operation easier. The pull ring 15 makes it easy for personnel to open the lid 10.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
