DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Please refer to Figures 1-5 A seal structure of degradable environment-friendly meal box, including lower connecting frame 3 and upper connecting frame 4 fixedly connected to the side wall of box body 1 and cover 2, the upper surface of lower connecting frame 3 is provided with socket 31, the bottom surface of upper connecting frame 4 is fixedly connected with plug 8, the outer wall of plug 8 is slidably connected with the inner wall of socket 31, both sides of lower connecting frame 3 are connected with two support assemblies, and the two support assemblies on the same side of lower connecting frame 3 are connected with connecting strip 7.

[0023] As Figures 1-5 Indicated, the seal structure of degradable environment-friendly meal box in the utility model can reduce the probability of food juice flowing out when storing food, first, the cover 2 is taken off together with the upper connecting frame 4 from the box body 1 and the lower connecting frame 3, then the food to be stored is placed inside the box body 1, and then the plug 8 of the cover 2 upper connecting frame 4 is inserted into the socket 31 of the lower connecting frame 3, and the sealing between the box body 1 and the cover 2 can be realized through the plug 8 and the socket 31.

[0024] Because when storing food, many times will use multiple box bodies 1 and covers 2 to store the same kind of food or different food at the same time, at this time, multiple foods can be stored in different box bodies 1, and after sealing (according to the above steps) by the cover 2, one end of the two connecting strips 7 on the two sides of the lower box body 1 is separated from one of the support assemblies, then it is folded upwards, passes through the upper side of the second cover 2, and is connected with the other support assembly on the other side of the first box body 1, and then the two degradable meal boxes (box body 1 and cover 2) can be bundled together through the two connecting strips 7, the connectivity of each other is increased, and the probability of loosening is reduced.

[0025] It needs to be particularly pointed out here that:

[0026] 1、The length of connecting strip 7 can be set to match the situation of exactly surrounding a circle (such as Figure 5 ), and matching with the support assembly on the other side, so that the surface of the cover 2 of the degradable meal box above can be closely attached, thereby increasing the friction between each other.

[0027] 2. The box body 1, cover 2, lower connecting frame 3, upper connecting frame 4, insert 8, connecting strip 7 and support assembly mentioned above are all made of food-grade and biodegradable materials, such as corn starch, cassava starch and other plant starch as the main raw materials, and the specific model is not limited.

[0028] like Figures 1-5 As shown, the support assembly includes a support piece 5 and an I-shaped rod 6. One end of the support piece 5 is hinged to the side wall of the lower connecting frame 3. The upper end of the I-shaped rod 6 passes through the other end of the support piece 5, and the outer wall of the I-shaped rod 6 is fixedly connected to the penetration point of the support piece 5. Both ends of the connecting strip 7 are penetrated by a connecting opening 74, and the lower end of the I-shaped rod 6 is slidably connected to the inner wall of the connecting opening 74.

[0029] More specifically, during normal use, the two connecting ports 74 at both ends of the connecting strip 7 are respectively sleeved on the outer wall of the thinner section in the middle of the two I-shaped rods 6, and are supported by the support piece 5 and the larger end of the lower end of the I-shaped rod 6, thereby preventing the connecting strip 7 from falling off; when it is necessary to erect the connecting strip 7 and connect it to the I-shaped rod 6 on the other side of the box body 1, it is only necessary to first remove one end of the connecting strip 7 from the I-shaped rod 6 on this side of the box body 1, and after wrapping around the upper lunch box, it is stuck on the other I-shaped rod 6 on the other side of the box body 1. It is simple and easy to operate.

[0030] like Figures 1-5 As shown, the inner wall of one of the connection ports 74 is provided with two deformation ports 75, which match the I-shaped rod 6. The side wall of the connection bar 7 near one end of the deformation port 75 is provided with an indicator arrow 73, which points in the direction of the deformation port 75.

[0031] More specifically, by providing the deformation opening 75, when one end of the connecting strip 7 is removed and another end is put on, it is convenient to snap into the I-shaped rod 6. By providing the indicator arrow 73, it is convenient for the user to know which end of the connecting strip 7 is the detachable end.

[0032] It should be noted that the two indicating arrows 73 on the two connecting bars 7 on both sides of the box body 1 are in opposite directions, that is, the detachable ends of the two connecting bars 7 are in opposite directions.

[0033] like Figures 1-5 As shown, a sleeve opening 71 is formed through the middle of the connecting strip 7. Side openings 72 are formed on both sides of the two ends of the connecting strip 7, and the width of the two side openings 72 is not greater than the width of the sleeve opening 71.

[0034] More specifically, by providing the sleeve opening 71 and the side opening 72 , when a plurality of lunch boxes are positioned in a row, the connecting strips 7 between adjacent lunch boxes will not conflict with each other.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
