DETAILED DESCRIPTION
[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0037] A food packaging bag suitable for microwave heating, see Figure 1-4 As shown, it includes: a bag body 100 and a supporting shell 200;
[0038] The bag body 100 includes: a first bag surface 110 and a second bag surface 120. After the first bag surface 110 and the second bag surface 120 are attached to each other, the bag body 100 is in a folded state. When the first bag surface 110 and the second bag surface 120 are relatively far away from each other, the bag body 100 is in an expanded state.
[0039] The first bag surface 110 and the second bag surface 120 may be connected in the following ways, all of which can achieve the purpose of forming a receiving space in the bag body 100:
[0040] The first connection method: the two side edges and the bottom edge of the first bag surface 110 and the second bag surface 120 are directly connected, and the top is formed to be open, and the opening is closed by heat sealing or the like;
[0041] The second connection method: the two sides of the first bag surface 110 and the second bag surface 120 are connected by the left side and the right side, and the bottom sides of the first bag surface 110 and the second bag surface 120 are connected by the bottom surface 130, and the top is formed with an opening, which is closed by heat sealing or other methods; in this connection method, the bag body 100 is more three-dimensional when it is opened;
[0042] The third connection method: the two side edges of the first bag surface 110 and the second bag surface 120 are directly connected, the bottom edges of the first bag surface 110 and the second bag surface 120 are connected through the bottom surface 130, the top forms an opening, and the opening is closed by heat sealing or the like.
[0043] In this embodiment, the bag body 100 is manufactured by adopting the third connection method.
[0044] Furthermore, the bag body 100 is made of paper material, and a waterproof layer can be provided on the inner wall surface and / or the outer wall surface of the bag body 100, and water can be injected for use;
[0045] Furthermore, the bag body 100 has the functions of high temperature resistance and flame retardancy, and is suitable for use in a microwave oven.
[0046] The supporting shell 200 includes:
[0047] The first supporting portion 210 is mounted on the outer wall of the first bag surface 110;
[0048] The second supporting portion 220 is mounted on the outer wall of the second bag surface 120;
[0049] The third supporting portion 230 is connected to the first supporting portion 210 and the second supporting portion 220;
[0050] When the bag body 100 is in a folded state, the third support portion 230 is folded;
[0051] When the bag body 100 is in the expanded state, the third support portion 230 is unfolded and laterally supported at the bottom of the bag body 100, so that the first bag surface 110 and the second bag surface 120 are kept in the expanded state;
[0052] The supporting shell 200 is made of paper material, specifically cardboard.
[0053] The first support portion 210 can be installed on the outer wall surface of the first bag surface 110 by gluing, and similarly, the second support portion 220 can be installed on the outer wall surface of the second bag surface 120 by gluing; optionally, the first support portion 210 and the first bag surface 110, and the second support portion 220 and the second bag surface 120 can be connected by other forms, such as hot melt connection.
[0054] Since the support shell 200 is made of cardboard, the first support portion 210, the second support portion 220 and the third support portion 230 can be cut from a piece of cardboard. After cutting, when the first support portion 210, the second support portion 220 and the third support portion 230 are laid out flat, the third support portion 230 is located between the first support portion 210 and the second support portion 220.
[0055] Alternatively, the first support portion 210, the second support portion 220 and the third support portion 230 are independently manufactured and then connected; however, it is preferred that they are made by cutting a piece of cardboard as mentioned above, which simplifies the process and reduces the subsequent connection steps.
[0056] The support shell 200 is made of cardboard, which is easy to recycle after use, and the production process is simple, and it can be directly cut by cardboard, which also reduces the assembly steps and effectively improves production efficiency.
[0057] Furthermore, the third support portion 230 includes: a first support plate 231 and a second support plate 232, the first support plate 231 and the second support plate 232 are connected, and the first support plate 231 is connected to the lower end of the first support portion 210, and the second support plate 232 is connected to the lower end of the second support portion 220; a crease a201 is formed at the connection between the first support plate 231 and the second support plate 232.
[0058] Folds b202 are formed between the first support plate 231 and the first support portion 210 , and between the second support plate 232 and the second support portion 220 , respectively, and openings are formed at the folds b202 .
[0059] The folds b202 formed between the first support plate 231 and the first support portion 210 and between the second support plate 232 and the second support portion 220 are to facilitate the deformation of the support shell 200 when the bag body 100 switches between the folded state and the expanded state;
[0060] like Figure 1 As shown, when the bag body 100 is in the folded state, the first bag surface 110 and the second bag surface 120 are overlapped, and the first support portion 210 and the second support portion 220 are overlapped with the first bag surface 110 and the second bag surface 120, and the first support plate 231 and the second support plate 232 of the third support portion 230 are folded. After the entire support shell 200 is folded, as shown in FIG. Figure 1 As shown, it is generally T-shaped, and the third support portion 230 is folded downward, that is, it extends downward along the bottom of the first support portion 210 and the second support portion 220;
[0061] Alternatively, when in the folded state, the first support plate 231 and the second support plate 232 are folded upward and stored between the first support portion 210 and the second support portion 220. However, this method requires that when the bag body 100 is in the folded state, there is enough space to allow the first support plate 231 and the second support plate 232 to fold upward, that is, the bottom surface 130 needs to have a sufficient width, otherwise the first support plate 231 and the second support plate 232 will interfere with the bottom surface 130 after being folded upward.
[0062] Furthermore, if Figure 3-4 As shown, the fold b202 is arranged as a non-linear line. When the third support portion 230 is bent along the fold b202 relative to the first support portion 210 and the second support portion 220, the first support portion 210 and the second support portion 220 are formed with support legs 240, and the bag body 100 is placed upright by the support legs 240;
[0063] Furthermore, if Figure 4 As shown, the bottom edge of the support foot 240 is arranged in a straight line, so as to be supported more stably on a plane;
[0064] like Figure 1 As shown, an opening b2021 is formed at the middle of the fold b202, and when the third support portion 230 is bent along the fold b202 relative to the first support portion 210 and the second support portion 220, the support foot 240 is formed at the position corresponding to the opening b2021;
[0065] When placed, the food packaging bag can be stably placed vertically by the support of the support feet 240.
[0066] In one embodiment, the first support portion 210 and / or the second support portion 220 is provided with a fold c203 , and the fold c203 forms an opening c2031 .
[0067] like Figure 1 and Figure 2 As shown, Figure 1 In the embodiment, the length of the first support portion 210 (length from left to right) is relatively large, extending from the left side to the right side of the first bag surface 110. Since the first support portion 210 is made of cardboard, when the bag body 100 is opened, although the support shell 200 plays a positioning role, the first support portion 210 also hinders the deformation of the first bag surface 110 when the bag body 100 is opened. Therefore, after the fold c203 and the opening c2031 are provided, when the bag body 100 is opened, the first support portion 210 is deformed accordingly, so that the first bag surface 110 is kept in a certain shape;
[0068] and Figure 2 In the embodiment, the second supporting portion 220 is relatively short and is approximately located in the middle of the second bag surface 120 , and the second supporting portion 220 does not need to be provided with a fold c203 .
[0069] Optionally, the second support portion 220 may also be configured to have the same structure and length as the first support portion 210.
[0070] Furthermore, the first bag surface 110 and the second bag surface 120 are provided with tear openings near the top opening.
[0071] The utility model is suitable for a food packaging bag for a microwave oven. The food packaging bag is as follows before leaving the factory: Figure 1 or Figure 2 The folded state shown is shipped from the factory, which is small in size, easy to store and transport, and reduces transportation costs;
[0072] The food packaging bag is mainly used to package rice, and the rice is about 1-2 servings of fast food. After the rice is placed in the bag body 100, the opening is sealed by heat sealing or the like. Of course, the opening may also be sealed by other methods. After the rice is placed in the bag body 100, since it is 1-2 servings of rice and can be vacuumed, the thickness of the entire food packaging bag is still relatively thin, and the support shell 200 has not yet opened the support bag body 100.
[0073] After the user purchases this instant rice food, when eating, the user tears the seal open through the tearing opening, stretches the bag body 100, and stretches the support shell 200 at the same time. Figure 3 As shown, the third support portion 230 is stretched out horizontally, so that the bag body 100 is stably kept in the stretched out state, water is injected into the bag body 100, and then the bag is put into the microwave oven, the food packaging bag can be stably placed, and can be taken out and eaten directly after heating. At the same time, the support shell 200 can also facilitate the user to take and put to a certain extent;
[0074] After eating, you can also fold the food packaging bag and recycle it, which is more environmentally friendly.
[0075] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
