Detailed Description
reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus or methods consistent with certain aspects of the invention, as detailed in the following claims.
The solution of the invention will be described in detail below with reference to the accompanying figures 1-5 and with reference to an embodiment. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
this embodiment provides an environmental protection packing box with double seal structure, as shown in fig. 3, including box body 1 and lid 3, lid 3 is used for covering the opening part at box body 1, and the material of box body 1 and lid 3 is degradable elastic plastic and makes, so, used packing box can complete natural degradation, has reduced the pollution to the environment.
In this embodiment, as shown in fig. 1, the opening of the box body 1 is provided with a first outer edge 2 extending downwards, and the joint of the first outer edge 2 and the box body 1 is provided with a first arc-shaped structure, so that when the box body 1 and the box cover 3 are fastened up and down, the first arc-shaped structure can reduce resistance, so that the fastening is more convenient and faster, the fastening is tighter, and the phenomena of rice and dish exposure and the like are not easy to occur; the lid 3 is provided with downwardly extending, can with the first outer edge 4 of 2 chucking of outer edge, and the second is provided with the second arc structure with first arc structure complex along 4 junctions with lid 3 outward.
the included angle between the first outer edge 2 and the vertical direction is 45 degrees, and if the included angle is 30 degrees, the buckling is tight, and the operation is not easy; if the included angle is 60 degrees, the box cover 3 is loose as a whole, and dishes are easy to spill out during packing; in conclusion, the included angle between the vertical direction and the selected angle is 45 degrees, so that the splashing of the meal during packaging can be effectively avoided, and the use difficulty can be reduced.
As shown in fig. 2, since the box cover 3 and the box body 1 are both made of elastic material, the elasticity of plastic is utilized to make the first outer edge and the second outer edge form a compact structure after being deformed by pressure, and due to the action of elasticity, the first outer edge 2 can support the second outer edge 4 outwards, and the second outer edge 4 is harder and has an inwards bound force to the second outer edge, so that the box cover 3 and the box body 1 are combined together tightly. So set up, utilize the elasticity of plastics, first outer edge 2 and the outer 4 chucking of second form sealed face, and sealed tight, carry the in-process, food can not spill easily, especially to the food of taking the soup, and because sealed tight, make food cleaner and more sanitary.
Meanwhile, the length of the first outer edge 2 is equal to that of the second outer edge 4, so that the area of the sealing surface is the largest, and the sealing is ensured to be tighter.
in a preferred scheme of this embodiment, in order to avoid long-term jolt and shake, an opening of the packing box is opened, and food is spilled, the packing box is further provided with a buckle structure, as shown in fig. 5, the buckle structure comprises a protrusion 5 and a slot 6 matched with the protrusion 5, the protrusion 5 is arranged on the first outer edge 2, and the slot 6 is arranged on the inner side of the second outer edge 4; and first outer edge 2 still is provided with the unlocking piece that drives arch 5 and break away from the draw-in groove, and unlocking piece is along the first both sides middle part downwardly extending along 2 outer edges, and protruding 5 sets up in the junction of unlocking piece and first outer edge 2. The buckle structure plays a role in reinforcing the sealing of the packing box once more, so that the sealing of the box cover 3 and the box body 1 is firmer.
after food is put into the box body 1, the box cover 3 is covered on the box body 1, the box cover 3 is pressed downwards, the first outer edge 2 is contracted inwards and elastically deformed by the force of the second outer edge 4 and the pressing downwards until the bulge 5 of the first outer edge 2 and the clamping groove 6 on the inner side of the second outer edge 4 form a buckle structure, and then the process is finished. When the box cover 3 needs to be opened, the unlocking piece is pressed inwards to drive the bulge 5 to be separated from the clamping groove 6, and then the box cover 3 is pulled upwards.
It should be noted that the unlocking piece is a trapezoidal-structure shifting plate 7, the protrusion 5 is a triangular-structure baffle, and the clamping groove 6 is arranged in a triangular structure, further, a right-angled triangle is selected as a clamping groove template, and the right-angled triangle has a long bevel edge and can slide down along the bevel edge when the box cover 3 is closed down; after the buckling is finished, the box cover is not easy to loosen due to the blocking effect of the vertical short side of the right-angled triangle, and the sealing performance of the box cover is improved.
It should be noted that, in order to simplify the processing technology, the trapezoidal-structure dial plate 7, the triangular-structure baffle plate and the box body 1 are of an integrated structure.
In the preferred scheme of this embodiment, the packing box is four terrace with edges structure, and along packing box's opening to bottom direction, four terrace with edges's cross-sectional area reduces gradually, and the unblock piece sets up the minor flank side at four terrace with edges structure, so, when placing the packing box, four terrace with edges structure can reduce the shared space of packing box, improves space utilization.
Further, the packing box of the quadrangular frustum pyramid structure in the present embodiment has an upper length of 168mm, an upper width of 113mm, a lower length of 140mm, a lower width of 86mm, and a height of 51 mm. Of course, the packing box may be configured in other sizes, such as 217mm in upper length, 145mm in upper width, 178mm in lower length, 108mm in lower width, and 48mm in height, as the case may be.
It should be noted that the terms "first," "second," and the like, as used herein, are not limited to a specific order, but are used merely to distinguish one element or function from another, and the terms "upper," "lower," and "inner" as used herein refer to directions in fig. 3.
the foregoing is considered as illustrative and not restrictive, and all changes coming within the spirit and principles of the invention are intended to be embraced therein.
