A kind of plastic packing box
Technical field
The present invention relates to a kind of plastic packing box.
Background technology
Plastic packing box, due to its significant advantage, is widely used, and existing plastic packing box comprises article putting groove and high frequency sealing edges.The plastic packing box of producing through plastic suction forming apparatus, for the ease of depositing, all be nested in together, because the shape of plastic packing box is the same, so the gap between plastic packing box is just very little, a little even fully glutinous together, being difficult to separately, needs manual removal, while with such plastic packing box, carrying out sealed package, if manual operation, lose time, reduce production efficiency, if mechanized operation, easily produce waste product, raise the cost.
Summary of the invention
The problems referred to above that the present invention need to solve are for above-mentioned the deficiencies in the prior art, and a kind of plastic packing box separated of being convenient to is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of plastic packing box, comprise the article putting groove be recessed to form on plastic sheet and plastic sheet downwards, the shape of the shape of article putting groove and the product of required packing is suitable, on plastic sheet, be provided with the high frequency sealing edges for sealing around article putting groove, on the plastic sheet on the both sides of high frequency sealing edges outlay groove, symmetry is recessed to form separation trough downwards, the degree of depth of separation trough is greater than the degree of depth of article putting groove, separation trough comprises epimere and hypomere, epimere is cylinder, and hypomere is inverted cone, and the diameter of the cone bottom surface of hypomere equals the diameter of the cylinder disc of epimere.
Described separation trough has two pairs at the most.
Compared with prior art, the invention has the beneficial effects as follows: when plastic packing box is nested in together, because the diameter of the cone bottom surface of the hypomere of separation trough equals the diameter of the cylinder disc of epimere, so the hypomere of the separation trough of upper strata plastic packing box can be stuck in the epimere place of lower floor's plastic packing box separation trough, just be separated with gap between such two plastic packing boxes, the width in this gap is consistent with the degree of depth of the hypomere of separation trough, when sealed package, no matter be manual operation or power operation, take plastic packing box all very convenient, after heat seal has sealed, the outer unnecessary part of high frequency sealing edges can be cut away, can not affect the outward appearance of product.
The accompanying drawing explanation
Fig. 1 is the structural representation of plastic packing box of the present invention;
Wherein, 1, plastic sheet, 2, article putting groove, 3, separation trough, 4, epimere, 5, hypomere, 6, high frequency sealing edges.
The specific embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of plastic packing box, comprise the article putting groove 2 be recessed to form on plastic sheet 1 and plastic sheet 1 downwards, the shape of the shape of article putting groove 2 and the product of required packing is suitable, on plastic sheet 1, be provided with the high frequency sealing edges 6 for sealing around article putting groove 2, on the plastic sheet 1 on the both sides of high frequency sealing edges 6 outlay grooves 2, symmetry is recessed to form separation trough 3 downwards, the degree of depth of separation trough 3 is greater than the degree of depth of article putting groove 2, separation trough 3 comprises epimere 4 and hypomere 5, epimere 4 is cylinder, hypomere 5 is inverted cone, the diameter of the cone bottom surface of hypomere 5 equals the diameter of the cylinder disc of epimere 4.
Separation trough 3 has two pairs at the most, and many productive costss can increase.
Plastic packing box of the present invention, when plastic packing box is nested in together, because the diameter of the cone bottom surface of the hypomere 5 of separation trough 3 equals the diameter of the cylinder disc of epimere 4, so the hypomere 5 of the separation trough 3 of upper strata plastic packing box can be stuck in epimere 4 places of lower floor's plastic packing box separation trough 3, just be separated with gap between such two plastic packing boxes, the width in this gap is consistent with the degree of depth of the hypomere 5 of separation trough 3, when sealed package, no matter be manual operation or power operation, take plastic packing box all very convenient, after heat seal has sealed, the outer unnecessary part of high frequency sealing edges can be cut away, can not affect the outward appearance of product.
