Detailed Description

The invention is further illustrated by the following figures and examples.

As shown in fig. 1, the food container comprises a bottom 1, a side wall 2 and a box eave 3, wherein the edge of the bottom 1 extends upwards to form the side wall 2, the side wall 2 and the bottom 1 form a cavity 4 for holding food, the side wall 2 extends outwards along a direction parallel to the bottom 1 to form the box eave 3, and a first inner wall surface 21 (not shown in fig. 1) and/or a first outer wall surface 22 (not shown in fig. 1) of the side wall 2 are arranged obliquely with the bottom 1; the side wall 2 at least comprises a first inclined part 23 integrally connected with the bottom part, a second inclined part 24 integrally connected with the box eave 3 and an arc-shaped transition part 25 integrally connected with the first inclined part 23 and the second inclined part 24; the slope 24 of the second slope part is greater than or equal to the slope 23 of the first slope part, the perimeter P2 of any cross section of the second slope part 24 is greater than the perimeter P3 of any cross section of the arc-shaped transition part 25, and the perimeter P3 of any cross section of the arc-shaped transition part 25 is greater than the perimeter P1 of any cross section of the first slope part 23. The food container is integrally in an inverted trapezoidal structure with a large upper part and a small lower part, when the food container is used for containing liquid food, the pressure of the bottom 1 of the food container can be properly reduced, and the slope of the second inclined part 24 is larger than or equal to that of the first inclined part 23, so that when a plurality of food containers are stacked, the food container is convenient to save space and separate from the food containers respectively. The direct connection of the first and second

inclined portions

23 and 24 may be subject to cracking due to internal stress concentration, upon application of force or impact vibration, and even to cracking due to internal stress in molding during demolding. The rounded design of the rounded transition 25 may distribute the stress to reduce its deformation. Meanwhile, the fillet can improve the mold filling property of the slurry, so that the slurry can flow easily and a complete product can be prepared.

The box brim 3 extends in a direction parallel to the bottom 1 to form two holding lugs 31, and the two holding lugs 31 are symmetrically arranged relative to the center of the box brim 3. Therefore, when a user uses the food container, the user can conveniently take the food container, and in order to avoid deformation of the food container, the two holding lugs 31 are symmetrically arranged relative to the center of the box brim 3. The food container may be provided with a plurality of holding lugs 31, from the use perspective, the holding lugs 31 are arranged in pairs, and any two holding lugs 31 arranged in pairs are symmetrically arranged relative to the center of the box eave 3. In consideration of practical needs and cost saving requirements, the length of the holding lug 31 is preferably 3-6cm, in this embodiment, the length of the holding lug 31 is 5cm, so that the container can be more effectively taken out and insulated.

From a production point of view, the use of a large number of short and narrow bars is superior to the use of several deep and wide bars. Therefore, in this embodiment, the reinforcing ribs are not provided on the whole side wall 2, but the first inclined portion 23 is integrally formed with the side wall reinforcing ribs 231 which are uniformly distributed, and the side wall reinforcing ribs 231 are connected with the bottom portion 1 in the arc transition manner and extend from the bottom portion 1 to the junction of the first inclined portion 23 and the arc transition portion 25. Each two adjacent sidewall ribs 231 are disposed in opposite directions. So that the food container can be more easily taken when stacked, and the side wall reinforcing ribs 231 increase the bearing capacity of the side wall 2. Increasing the strength of the food container by increasing the thickness of the sidewall alone is impractical in actual manufacture and use due to the tendency to produce shrinkage cavities and dents. In this embodiment, the food container employs the sidewall reinforcement rib 231 to improve the method of the container structure. The sidewall reinforcement rib 231 can improve the flow of the slurry during the formation of the slurry (especially, when the sidewall reinforcement rib 231 is disposed in the direction of the slurry flow) in addition to enhancing the strength and rigidity of the food container. The arrangement of the side wall reinforcing ribs 231 is consistent with the material flow direction, so that the material flow is prevented from being disturbed, and the toughness of a finished product is reduced. In this embodiment, the two adjacent side wall ribs 231 are arranged in opposite directions, so that the thickness of the side wall can be effectively increased, and the tolerance of the side wall 2 of the food container can be increased.

In this embodiment, because first inclined portion 23 is narrow structure about wide, the lateral wall strengthening rib 231 is provided with sufficient inclination along first inclined portion 23, and the joining of lateral wall strengthening rib 231 and bottom 1 is the circular arc transition, has avoided first inclined portion 23 and bottom 1 handing-over part because stress concentration, takes place to break when atress or receiving impact vibration, makes circular arc transition or fillet even because internal stress fracture in the drawing of patterns process, can effectively increase food container's sturdiness.

As shown in fig. 2, the depth of the container is generally too great and the structure of the food container will likely expand under load. In this regard, in the present embodiment, it is necessary to maintain the ratio of the first inclined portion 23 to the second inclined portion 24, the length L2 of the second inclined portion 24 in the direction perpendicular to the bottom portion 1, the length L3 of the arc-shaped transition portion 25 in the direction perpendicular to the bottom portion 1, and the length L1 of the first inclined portion 23 in the direction perpendicular to the bottom portion 1 in a reasonable range of (13-15); (1-2): (40-50). Considering that the food container of the present embodiment has an inverted trapezoidal structure with a large top and a small bottom, when the food is in a liquid state, the arrangement is such that the pressure of the food is relieved. In countless practices, it is not practical to increase the strength of the container by increasing the thickness of the sidewall, which may cause shrinkage cavities and dents, and also increase the cost of the raw materials. In the present embodiment, the thickness of the side wall 2 is preferably 0.03 to 0.3mm according to the ratio and size of Rong Shenzhong, the first and second

inclined portions

23 and 24. In the present embodiment, the length L1 of the second inclined portion 24 in the direction perpendicular to the bottom portion 1 is 15cm, the length L3 of the arc-shaped transition portion 25 in the direction perpendicular to the bottom portion 1 is 1.7cm, and the length L1 of the first inclined portion 23 in the direction perpendicular to the bottom portion 1 is 45cm, and the thickness of the side wall of the food container in the present embodiment is 0.1mm from the viewpoint of compatibility between use and cost.

As shown in fig. 1, in this embodiment, the central portion of the bottom 1 is provided with an integrally formed trapezoidal boss 11 protruding toward the direction of the cavity 4, the height of the trapezoidal boss 11 protruding toward the direction of the cavity 4 is preferably 0.3-0.5mm, and in this embodiment, the height of the trapezoidal boss 11 protruding toward the direction of the cavity 4 is preferably 0.4mm, which is an effective height obtained after multiple tests, and therefore, the food container does not occupy too much space of the cavity, can reduce the supporting surface of the bottom 1 of the food container to the maximum extent, and is easy to place stably.

As shown in fig. 3, the arrangement of the bottom reinforcing bars 12 is preferably criss-crossing, similar to a cross, a grid or a radial arrangement of reinforcing bars, the criss-crossing arrangement being able to accommodate many different load array variations. A correctly designed cross-over structure, which can withstand the expected stresses, ensures an even distribution of the stresses over the entire food container. The nodes formed at the intersections (fig. 3) represent an accumulation of material, but the nodes may be hollowed out as shown in this embodiment to prevent problems. In this embodiment, the bottom portion 1 is provided with an integrally formed bottom reinforcing rib 12, the bottom reinforcing rib 12 is arranged in a grid shape, the distance between any two parallel bottom reinforcing ribs 12 is 6cm, the height between the bottom reinforcing rib 12 and the bottom portion 1 is 0.1-0.3mm, and in this embodiment, the height between the bottom reinforcing rib 12 and the bottom portion 1 is 0.2mm.
