Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, and in particular relates to an improved structure of a self-heating medicinal food can. Background Technology

[0002] Self-heating canned food, as a food packaging form that does not rely on external heat sources and is easy to operate, is widely used in the food packaging industry. With its core advantages of instant heating and portable storage, it has deeply covered diverse scenarios such as outdoor travel, emergency reserves, and daily fast food, meeting people's demand for convenient food in the fast-paced modern life. Especially for medicinal food products that combine food attributes with health benefits, the application of self-heating canned food is more targeted and valuable. Medicinal food products usually use ingredients that are both food and medicine as raw materials, which need to be heated at an appropriate temperature to release effective ingredients, while avoiding high temperatures that could destroy heat-sensitive nutrients.

[0003] Chinese patent application N220032815U discloses a self-heating medicinal food canning device with a herbal medicine packet, including a box body, a lid, and a container assembly. The box body has a cavity with a top opening, and the lid is detachably mounted on the box body and covers the top opening of the cavity. A heating pack and a herbal medicine packet are placed inside the cavity. The container assembly includes a container body and at least one filter screen. The container body is located inside the cavity and above the heating pack, and is used to hold the medicinal food ingredients and herbs. The filter screen is removable and can be inserted into the container body for filtering out the dregs from the herbs. The filter screen has a handle for removing it from the container body. This invention heats the herbs and medicinal food ingredients simultaneously, effectively preserving their active ingredients. The filter screen filters out the dregs from the herbs, confining them within the container body, making it convenient to eat while effectively maintaining the taste of the medicinal food ingredients and herbs.

[0004] Although the patented design features a split-type box structure (an upper and lower box assembly), and includes a partition in the lower box to separate the heating chamber, allowing for convenient replacement of the heating pack and multiple heating operations, thus enhancing the device's reusability, the assembly connection between the upper and lower boxes lacks a sealing and protective component. It relies solely on simple splicing for connection, making it easy for heat and steam generated in the lower box to escape through this gap during heating. This reduces heat transfer efficiency, prolongs the heating time of the medicinal food, and allows cold air to seep in, further affecting the heating effect. Therefore, it fails to meet the core requirements of self-heating medicinal food cans for sealing, pressure preservation, and efficient temperature control.

[0005] To address these issues, we provide an improved structure for self-heating medicinal food cans. Utility Model Content

[0006] The purpose of this invention is to provide an improved structure for self-heating medicinal food cans. By combining the sealing components and the top cover, the problem of insufficient sealing in existing self-heating medicinal food cans is solved.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an improved structure for a self-heating medicinal food can, comprising an outer can, an inner can within the inner cavity of the outer can, a top cover movably connected to the top of the outer can, and a sealing assembly at the bottom of the top cover. The sealing assembly includes a buckle, one side of the top of the buckle being rotatably connected to the outer can, and a locking block engaging at the bottom of the buckle. The other side of the locking block is fixedly connected to the outer can, and a sealing gasket is fixedly connected to the bottom of the top cover. A sealing tooth is embedded on the inner side of the bottom of the sealing gasket, and the bottom of the sealing tooth is fixedly connected to the outer can. There are two locking blocks and two buckles, symmetrically distributed on both sides of the outer can, which ensures that the top cover is evenly stressed during locking, avoiding top cover displacement or local compression deformation of the sealing gasket caused by unilateral stress, further ensuring the fitting accuracy between the sealing assembly and the outer can. One side of the bottom of the locking block is inclined, so that when the buckle engages, the contact force is converted into downward pressure, causing the top cover to move automatically downward, and the fitting degree between the sealing gasket and the sealing tooth gradually deepens during the engagement process, achieving a dynamic sealing effect of tightening with increasing pressure.

[0009] The present invention is further configured such that anti-scalding components are provided on both sides of the inner can. Each anti-scalding component includes a fixing block, the rear side of which is fixedly connected to the inner can. Fixing rods are fixedly connected to both sides of the fixing block, and damping pads are fixedly connected to the surface of the fixing rods. Rotary handles are slidably connected to the surface of the damping pads. The rotary handles are located on both sides of the outer can. When holding the rotary handles on both sides, the hands can naturally avoid the opening area of ​​the can, reducing the probability of the hands coming into contact with the high-temperature opening edge or leaking steam during the handling process, and further reducing the risk of burns.

[0010] The present invention is further configured such that a pressure relief hole is provided on one side of the top of the upper cover, and a sealing cover is provided on the top of the pressure relief hole. One side of the sealing cover is rotatably connected to the upper cover. The pressure relief hole can release the excessive pressure generated by the accumulation of steam in the tank in time during the heating process, effectively avoiding the risk of the outer tank expanding, deforming or even breaking due to excessive pressure.

[0011] The present invention is further configured such that there are two rotating handles, which are symmetrically distributed on both sides of the inner can. With the two rotating handles symmetrically distributed on both sides of the inner can, the user can hold them with both hands when picking them up or putting them down, so that the force is applied more evenly and the inner can can be stably controlled.

[0012] The present invention is further provided that the surface of the inner tank is provided with a heat insulation layer, one side of which is fixedly connected to the outer tank. The heat insulation layer can effectively block the heat from being transferred outward when the medicinal food in the inner tank is heated, and prevent the temperature of the outer tank from rising due to excessive heat absorption.

[0013] The present invention is further configured such that a limiting block is provided on one side of the handle, and one side of the limiting block is fixedly connected to the fixing rod. The limiting block can restrict the movement of the handle and prevent it from detaching from the surface of the fixing rod.

[0014] The present invention is further configured such that a limiting plate is provided on the top of the fixing block, and one side of the limiting plate is fixedly connected to the inner tank. The limiting plate can restrict the range of motion of the rotating handle, so that it can only rotate downward.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model's sealing component, through the engaging engagement of a buckle and a locking block, combined with the rotating connection design between the buckle and the outer can, achieves mechanical locking and fixation between the upper cover and the outer can. This effectively prevents the cover from loosening due to steam pressure inside the can during heating, providing mechanical structural protection for the sealing effect and improving sealing stability. Furthermore, the sealing gasket at the bottom of the upper cover and the sealing teeth of the outer can interlock to form a multi-layered sealing structure. When the buckle and the locking block engage, the upper cover moves downward, causing the sealing teeth to embed into the sealing gasket. Compared to traditional flat seals, the interlocking design increases the tightness of the sealing contact, accurately preventing high-temperature steam from leaking from the connection between the cover and the can, reducing heat loss, ensuring the stability of steam circulation inside the can, and facilitating uniform heating of medicinal cuisine.

[0017] 2. The anti-scalding component of this utility model can effectively isolate the high temperature transmitted by the inner can after the inner can is heated through the indirect connection design between the handle and the inner can, so as to avoid the user from directly contacting the hot can body when picking up or putting down the inner can and causing burns. It provides safety protection for the user and significantly improves the safety of use. The damping pad on the surface of the handle and the fixing rod are slidably connected, so that the handle will not rotate by gravity when the inner can is heated. The handle can also be rotated as needed to decide whether to use it. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-5 This utility model is an improved structure of a self-heating medicinal food can, including an outer can 1, an inner can 2 inside the outer can 1, a top cover 3 movably connected to the top of the outer can 1, a sealing component 4 at the bottom of the top cover 3, the sealing component 4 including a buckle 401, one side of the top of the buckle 401 being rotatably connected to the outer can 1, a locking block 402 being engaged at the bottom of the buckle 401, the other side of the locking block 402 being fixedly connected to the outer can 1, a sealing gasket 403 being fixedly connected to the bottom of the top cover 3, a sealing tooth 404 being fitted into the inner side of the bottom of the sealing gasket 403, and the bottom of the sealing tooth 404 being fixedly connected to the outer can 1.

[0027] Specifically: There are two of each of the locking blocks 402 and the buckles 401, which are symmetrically distributed on both sides of the outer tank 1. This ensures that the upper cover 3 is subjected to uniform force during the locking process, avoiding the offset of the upper cover 3 or the local compression and deformation of the sealing gasket 403 caused by unilateral force. This further ensures the fitting accuracy between the sealing component 4 and the outer tank 1. The bottom side of the locking block 402 is inclined, so that when the buckle 401 is engaged, the contact force can be converted into downward pressure, which drives the upper cover 3 to move down automatically. This causes the fitting degree between the sealing gasket 403 and the sealing teeth 404 to gradually deepen during the engagement process, achieving a dynamic sealing effect that becomes tighter with increasing pressure.

[0028] Please see Figure 1-5The inner tank 2 is equipped with anti-scalding components 5 on both sides. The anti-scalding components 5 include a fixing block 501, which is fixedly connected to the inner tank 2 at the rear. Fixing rods 502 are fixedly connected to both sides of the fixing block 501. Damping pads 503 are fixedly connected to the surface of the fixing rods 502. Rotary handles 504 are slidably connected to the surface of the damping pads 503. A pressure relief hole 6 is opened on one side of the top of the upper cover 3. A sealing cover 7 is set on the top of the pressure relief hole 6. One side of the sealing cover 7 is rotatably connected to the upper cover 3. There are two rotary handles 504, which are symmetrically distributed on both sides of the inner tank 2. A heat insulation layer 8 is provided on the surface of the inner tank 2. One side of the heat insulation layer 8 is fixedly connected to the outer tank 1. A limit block 9 is set on one side of the rotary handle 504. One side of the limit block 9 is fixedly connected to the fixing rod 502. A limit plate 10 is set on the top of the fixing block 501. One side of the limit plate 10 is fixedly connected to the inner tank 2.

[0029] Specifically: The handles 504 are located on both sides of the outer can 1. When holding the handles 504 with both hands, the hands can naturally avoid the opening area of ​​the can, reducing the probability of the hands coming into contact with the hot opening edge or leaking steam during the picking and placing process, further reducing the risk of burns. The pressure relief hole 6 can release the excessive pressure generated by the accumulation of steam in the can during the heating process, effectively avoiding the risk of the outer can 1 expanding, deforming or even breaking due to excessive pressure. The two handles 504 are symmetrically distributed on both sides of the inner can 2. When picking and placing, the user can hold them with both hands respectively, making the force more even and stable in controlling the inner can 2. The heat insulation layer 8 can effectively block the heat from the inner can 2 during the heating of Chinese medicinal cuisine from being transferred outward, preventing the inner wall of the outer can 1 from absorbing too much heat and causing the outer wall temperature to rise. The limiting block 9 can restrict the movement of the handles 504 to prevent them from detaching from the surface of the fixing rod 502. The limiting plate 10 can limit the range of movement of the handles 504, making them only able to rotate downward.

[0030] The working principle of this utility model is as follows: When in use, the heating pack and water are added to the inner cavity of the outer tank 1. The rotating handles 504 on both sides of the inner tank 2 are opened. The rotating handles 504 rotate along the fixed rod 502 and are locked by the damping pad 503. Then, the inner tank 2 is placed in the inner cavity of the outer tank 1, with the rotating handles 504 on the outside. Because of the existence of the limiting plate 10, the rotating handles 504 will not rotate upward when the user takes the inner tank 2 through the rotating handles 504. Then, the top cover 3 is placed on the top of the outer tank 1 and the buckles 401 on both sides are rotated. When the buckles 401 come into contact with the locking block 402, they are squeezed and moved down along the inclined surface. The buckles 401 drive the top cover 3 to move down, and the top cover 3 drives the sealing gasket 403 to move down. After the sealing gasket 403 comes into contact with the sealing teeth 404, the sealing teeth 404 are embedded into the sealing gasket 403 through the top cone shape, so as to achieve a tight seal.

[0031] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
