Description

Packaging structure of disaster relief food Technical Field

[0001] This disclosure pertains to a packaging structure, particularly a packaging structure for disaster-prevention food with multiple physical barriers to extend shelf life. Prior Technology

[0002] Existing disaster relief foods mostly consist of biscuits or dried grains, which, although they have a long shelf life, often lack flavor variation and have a limited range of nutrients.

[0003] For foods containing oils or complex ingredients, traditional packaging methods often mix all dried ingredients and seasonings in the same container. This configuration makes it difficult to overcome physical and chemical deterioration problems such as oil oxidation and clumping due to moisture, resulting in severely limited shelf life and failing to meet the stringent requirement of long-term storage of disaster preparedness materials for three to five years. Summary of the Invention

[0004] The main purpose of this disclosure is to address the problems caused by the current traditional packaging methods that mix ingredients of different properties, which can easily lead to moisture transfer, oil oxidation, and clumping due to dampness, thus limiting shelf life.

[0005] To achieve the above objectives, this disclosure provides an embodiment of a food packaging structure for disaster prevention, comprising: a food storage section having a plurality of partitions to define the food storage section as a main food storage area, an oil-free food storage area, and an oily food storage area that are physically separated from each other; and a plurality of sealing portions respectively disposed around the periphery of the main food storage area, the oil-free food storage area, and the oily food storage area to seal the main food storage area, the oil-free food storage area, and the oily food storage area and block outside air.

[0006] Based on the above, the effectiveness of this disclosure lies in the fact that, through the layered packaging mechanism design, the main ingredients, oil-free ingredients, and oil-containing ingredients are separately placed in physically isolated areas, effectively preventing moisture transfer and oil oxidation reactions between ingredients of different properties, maintaining an environment with extremely low oxygen and low water activity, and ensuring the stability of the ingredients during long-term storage; at the same time, the sealing part blocks the outside air, achieving the expected technical effect of physical isolation and chemical stability, and greatly extending the shelf life of disaster relief food.

[0008] To more clearly illustrate the core ideas above, specific examples are provided below. Please note that the proportions of the objects in these examples are for illustrative purposes only and are not drawn to the actual proportions of the components.

[0009] Referring to Figures 1 to 5, this disclosure presents an embodiment of a food packaging structure 100 for disaster prevention, primarily used for the long-term storage of composite ingredients with different properties. Through physical isolation, it achieves the technical effect of extending shelf life. The packaging structure 100 includes an ingredient containing portion 10, a plurality of partition portions 20, and a plurality of sealing portions 30.

[0010] The food storage section 10 is divided by multiple partitions 20, which further define a main food storage area 11, an oil-free food storage area 12, and an oil-containing food storage area 13 that are physically separated from each other.

[0011] Multiple partitions 20 are disposed between the main food storage area 11, the oil-free food storage area 12, and the oily food storage area 13, forming a stable boundary. Furthermore, the sealing width of the partitions 20 is greater than the peripheral width of the sealing portion 30. Since the partitions 20 must withstand physical compression from two adjacent storage areas (the main food storage area 11, the oil-free food storage area 12, or the oily food storage area 13), the wider partitions 20 provide stronger structural support, preventing cross-area leakage or mixing of food during transportation or under pressure.

[0012] Multiple sealing sections 30 are disposed around the periphery of the main ingredient storage area 11, the oil-free ingredient storage area 12, and the oil-containing ingredient storage area 13. The multiple sealing sections 30 seal the main ingredient storage area 11, the oil-free ingredient storage area 12, and the oil-containing ingredient storage area 13 in an airtight manner to prevent the entry of external air and moisture. In another embodiment, the internal spaces of the main ingredient storage area 11, the oil-free ingredient storage area 12, and the oil-containing ingredient storage area 13 are maintained in a negative pressure vacuum state. This solves the problem of oil oxidation and moisture transfer caused by mixing multiple composite ingredients with different properties in the prior art, thereby achieving the effect of maintaining an extremely low oxygen and low water activity environment for the ingredients.

[0013] Referring to Figures 1 and 2, another embodiment of this disclosure reveals that the packaging structure 100 further includes a plurality of tear-away portions 31. The tear-away portions 31 are disposed on the sealing portions 30 corresponding to the main ingredient containing area 11, the oil-free ingredient containing area 12, or the oil-containing ingredient containing area 13. The tear-away portions 31 are formed into a V-shaped notch or a serrated structure. Therefore, in the event of an emergency, the user can easily tear open the packaging by hand along the stress concentration points of the tear-away portions 31 without the need for a knife, greatly improving operational convenience.

[0014] Please refer to Figures 1 and 2. Another embodiment of this disclosure reveals a selective disassembly mechanism for the packaging structure 100 under extreme disaster scenarios. When the packaging structure 100 encounters extreme harsh environments or exceeds its preset shelf life and faces an urgent need for consumption, based on the physical isolation characteristics defined by the divider 20, the user can use the corresponding easy-tear section 31 to tear and discard the oily food storage area 13, which is more prone to oil oxidation and deterioration, and only open and consume the unaffected food stored in the main food storage area 11 and the oil-free food storage area 12. In this way, the problem of traditional mixed food in the prior art where the entire package of food becomes unusable and inedible once local oil spoilage occurs can be solved. This achieves a flexible consumption effect that maximizes the retention of usable materials and ensures the user's safe intake of basic calories under extreme or expired conditions.

[0015] Referring to Figure 3, in one embodiment, the main ingredient containing area 11, the oil-free ingredient containing area 12, and the oily ingredient containing area 13 are arranged with alternating transparent and opaque materials. For example, one side of the packaging material can be made of transparent material, and the other side can be made of opaque material such as aluminum foil; or different materials can be selected for different containing areas according to the characteristics of the ingredients. Alternatively, an opaque material can be coated on the adjacent positions of the transparent material. The opaque material can prevent the rancidity of oils or the loss of vitamins caused by light exposure, while the transparent material allows users to quickly check the state of the contents (e.g., to check whether the powder has become damp and clumped), achieving the effect of both light protection and quick confirmation of the quality of the ingredients.

[0016] Referring to Figure 4, in one embodiment, the main ingredient storage area 11 contains carbohydrate staple foods, the oil-free ingredient storage area 12 contains dried oil-free ingredients, and the oily ingredient storage area 13 contains a plurality of oily ingredients. For example, the main ingredient storage area 11 contains Hakka salted Lei Cha powder or dried rice, the oil-free ingredient storage area 12 contains dried vegetables, seaweed, or dehydrated fruit, and the oily ingredient storage area 13 contains peanuts, sesame seeds, or nuts. This independent partitioning effectively solves the common problems of oil oxidation and moisture transfer when mixing compound ingredients, ensuring that various ingredients maintain their original flavor and crispness during storage.

[0017] Referring to Figure 5 and in conjunction with Figures 1 to 4, the packaging structure 100 further includes an outer container 40. The outer container 40 holds the food storage section 10, forming a double-sealed structure around it. The outer container 40 is a metal can (e.g., tinplate can, aluminum can, tinplate can, multi-layered laminated metal can, or stainless steel container), and its internal space is filled with one or a combination of inert gases (e.g., nitrogen or argon) and carbon dioxide to create a low-oxygen environment. By combining the internal negative pressure vacuum of the food storage section 10 with the external inert gas environment of the outer container 40, a multi-layered protective mechanism can be constructed, enabling disaster-resistant food to withstand extreme weather conditions and extending its stable storage period to three to five years.

[0018] Based on the above, the advantages of this disclosure are:

[0019] 1. Advantages of the core structure: The partition 20 completely and physically separates the main ingredient storage area 11, the oil-free ingredient storage area 12, and the oil-containing ingredient storage area 13, thus completely preventing moisture transfer and oil oxidation between ingredients.

[0020] 2. Improved ease of use: The easy-tear part 31 on the sealing part 30 ensures that users can intuitively and quickly open the seal by hand in emergency disaster situations, and use it immediately after opening.

[0021] 3. Enhanced durability: The outer container 40, combined with the internal negative pressure vacuum state, provides a double protective sealing mechanism, which greatly enhances the physical pressure resistance and chemical stability of disaster relief food in harsh environments.

[0022] 4. Optimized preservation performance: The alternating combination of transparent and opaque materials blocks light damage and facilitates inspection of the contents of the packaging structure 100.

[0023] The embodiments described in this disclosure are for illustrative purposes only. Those skilled in the art will understand that the various features, elements, or steps of this disclosure are not mutually exclusive, but can be combined, modified, or replaced in various ways as needed without departing from the spirit and scope of this disclosure.
