[0031] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0032] Example 1

[0033] A food packaging container, such as Figure 1-4 As shown, the overall structure includes an inner package 1 , an outer package 2 and an outer cover 3 . The inner package 1 is placed at the center of the outer package 2 , and the outer cover 3 seals the outer package 2 .

[0034] Dividing the food packaging container into an inner package 1 and an outer package 2 is advantageous in that the inner package 1 and the outer package 2 are made of different materials, thereby saving costs. It is also advantageous in that the food is safely protected during storage, handling, transportation, and sales. For example, powdered food or liquid food needs to be packaged with food-grade safety materials and also requires extremely high sealing properties. Dividing the food packaging container into an inner package 1 and an outer package 2 allows only the inner package 1 to be made of high-cost packaging materials, while the outer package 2 can be made of conventional paper, plastic, metal, etc., and can be strengthened by, for example, lamination or bending processes, to protect the inner package 1. Figure 3 and Figure 4 As shown, the outer packaging 2 in this embodiment is a shell structure, including an outer shell 21 and an inner shell 22 connected to the inside of the outer shell 21. Although the material of this shell does not need to be very thick, the strength can be improved through bending processing and reinforcements 23 including side ribs and bottom supports between the outer shell 21 and the inner shell 22, thereby effectively forming support and protection.

[0035] A further improvement of this embodiment is that a guiding slope 221 is provided on the inner peripheral wall of the outer package 2 to facilitate placement of the inner package 1 into the outer package 2. Figure 3 and Figure 4 As shown, the guide bevel 221 is provided on the aforementioned inner shell 22. Powdered or liquid foods require filling during the production process. The inner package 1 in the present invention is used directly to hold the food. Since the filled food has a certain volume or weight, when designing the filling line, it is preferable to first position the inner package 1 within the outer package 2 before performing the food filling process. The guide bevel 221 provided on the inner circumferential wall of the outer package 2 helps the machine improve the positioning accuracy when placing the inner package 1 within the outer package 2. Of course, if this step is performed manually, the guide bevel 221 also provides the same benefits to the operator.

[0036] In addition, as is preferred but not required, Figure 4 As shown in the figure, the inner shell 22 may further have a vertical surface 222 in addition to the guiding inclined surface 221. The vertical surface 222 is arranged at the end of the guiding inclined surface 221, which has an improved stabilizing effect on the inner package 1 inside.

[0037] A further improvement of this embodiment is that a first positioning portion 31 and a second positioning portion 32 are provided on the side of the outer cover 3 facing the opening of the outer package 2. The first positioning portion 31 cooperates with the opening of the outer package 2 to close the opening of the outer package 2, and the second positioning portion 32 cooperates with the upper part of the inner package 1 to coordinately achieve the function of limiting the inner package 1 while the first positioning portion 31 closes the opening of the outer package 2.

[0038] It should be noted that although many inner packages 1 are containers with lids on top, and this is also illustrated in the drawings of this utility model, the scope of application of this utility model is not specifically limited to the top of the inner package 1 being a lid. In some specific products, the inner package 1 may receive food through openings in other locations, or package food in a special packaging method. Therefore, the "upper portion of the inner package" mentioned throughout this utility model is preferably the lid, but not necessarily the lid.

[0039] In addition, the first positioning portion 31 of the present invention can be combined with the opening of the outer package 2 in various ways. For example, the first positioning portion 31 can be connected to the opening of the outer package 2 by fitting, snapping or screwing.

[0040] While the first positioning portion 31 closes the opening of the outer package 2, the second positioning portion 32 limits the inner package 1, completing the inner and outer packaging process of the food, and ensuring the stability and safety of the inner package 1 in the outer package 2, playing a multiple role of preventing squeezing, falling, collision and shaking.

[0041] Example 2

[0042] In the embodiment 1 introduced above, the basic function of the outer cover 3 has been provided, namely: the first positioning portion 31 closes the opening of the outer package 2 while the second positioning portion 32 limits the inner package 1, and this limitation is not limited to horizontal or vertical.

[0043] Next, if Figure 5 As shown, this embodiment further optimizes the limiting structure of the outer cover 3 in Example 1, so that while the first positioning portion 31 closes the opening of the outer package 2, the second positioning portion 32 simultaneously limits the inner package 1 horizontally and vertically.

[0044] Specifically, in Figure 5 In (A), the second positioning portion 32 includes two stop ribs 321. Figure 5 (B) It can be seen that the inner package 1 is limited both laterally and longitudinally by two stop ribs 321 , one of the stop ribs 321 stops at the outside of the inner package 1 , and one of the stop ribs 321 stops at the top of the inner package 1 .

[0045] It should be noted that, in order to illustrate that the stop rib 321 can have multiple functions, in particular Figure 5 (B) provides an example of an inner package 1 with a flange on the cover. In this example, a stop rib 321 at the top of the inner package 1 not only serves to limit the inner package 1 longitudinally, but also serves to limit the inner package 1 to a certain extent laterally because it is adjacent to the inner side of the flange on the cover of the inner package 1. Obviously, the inner package 1 in this embodiment may also not have the above-mentioned flange.

[0046] It should also be noted that the present invention mentions "a stop rib" rather than "one stop rib" because the stop rib 321 at each location is not necessarily in the form of a continuous ring, a rotating body, etc., but may be distributed in an intermittent manner, that is, the number of the stop rib 321 at each location may be one or more.

[0047] Example 3

[0048] This embodiment is a modification of the second embodiment, and this modification is used to reflect possible changes of the second positioning portion 32 .

[0049] like Figure 6 As shown in FIG. 2A , in this embodiment, one of the stop ribs is replaced with a stop boss 322 .

[0050] like Figure 6 As shown in (B), the second positioning portion 32 can also achieve the effect of simultaneously limiting the inner package 1 in the horizontal and vertical directions through a stopping rib 321 and the above-mentioned stopping boss 322.

[0051] Similarly, if the cover of the inner package 1 has a flange, the stop boss 322 can limit the longitudinal position of the inner package 1 and also play a certain role in lateral positioning.

[0052] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited to this. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention.
