Abstract
The utility model relates to a packaging box, comprising a box body and a sealing mechanism. The box body is composed of a bottom surface, a left side wall, a right side wall, a front side wall and a back side wall. The sealing mechanism comprises four identical sealing elements, and the sealing elements are respectively composed of the upper parts of corresponding side walls. The sealing elements are provided with twisting creases, one end of the twisting creases is at a junction between the side edges of the sealing elements and the corresponding side walls, and the other end of the twisting creases is at the other side edges of the sealing elements near top ends. The sealing elements are positioned at the same plane with the corresponding side walls in original opening state. Strengthening creases are arranged at the junction between the sealing elements and the corresponding side walls. The upper ends of the sealing elements are provided with the strengthening creases. One end of the strengthening creases are coincident with the upper ends of the twisting creases at the side edges of the sealing elements, and the other end of the strengthening creases are coincident with the upper ends of the twisting creases of contiguous sealing elements at the other side edges of the sealing elements. Symmetrical triangular notches are removed from the middle parts of the left and the right two sides of the sealing elements, and the bottom edges of the triangular notches are coincident with the side edges of the triangular notches.
Description
Technical field
The utility model relates to a kind of packing container, more specifically to a kind of packing box.
Background technology
The current packaging box adopts lid to seal usually, and especially food such as candy, jelly adopts transparent plastic box to pack, but its moulding is mostly too simple.In order to address this problem, present packing box is mostly taked common packing box is carried out big transformation, reaches purpose handsome in appearance, has increased manufacturing cost greatly, and complex structure, be difficult for to realize.
Summary of the invention
At the above-mentioned defective of prior art, the utility model provides a kind of packing box, and the technical scheme of employing is as follows:
Packing box of the present utility model, comprise box body and sealing mechanism, box body is made up of bottom surface, left side wall, right side wall, front side wall and rear wall, it is characterized in that: described sealing mechanism comprises four identical sealing members, each sealing member is made up of the first half of corresponding sidewall respectively, sealing member is provided with and reverses folding line, this reverses folding line one end at the side of sealing member and the intersection of corresponding sidewall, near top end, each sealing member is in the same plane with corresponding side walls under original opening at another side of sealing member for the other end.
In order to increase the intensity of packing box, the intersection between described sealing member and the corresponding sidewall is provided with the reinforcement folding line.
For the stability of sealing mechanism under sealing state that improves packing box, the upper end of described sealing member is provided with the reinforcing folding line, reinforce an end of folding line and reverse the side coincidence of the upper end of folding line at sealing member, the other end reverses the upper end coincidence of folding line with the adjacent seals part on another side of sealing member.
For the ease of twist seal and enhancing aesthetic feeling, symmetrical vee is removed at the middle part of the left and right sides of described sealing member respectively, and the base of this vee and side overlap.
In order to strengthen the aesthetic feeling of packing box, at least one is curve in the two other limit of described vee except that the base.
When the needs sealing packaging box, it is flat that two adjacent sealing members are pinned the middle part folder that reverses folding line, and the folding line that reverses of two sealing members is contacted, and its contact point is for reversing a little; It is flat that other two adjacent sealing members are pinned the middle part folder that reverses folding line equally, and the folding line that reverses of two sealing members is contacted, and its contact point is for reversing a little.Firmly make two then and reverse a relative motion, reverse a coincidence up to two, reach sealing state.At this moment, because the mutual action of each sealing member makes sealing mechanism remain on sealing state.When needing to open, firmly make two to reverse some motion round about, just can opening encapsulation mechanism.
The beneficial effect of the utility model contrast prior art is and since sealing member by the first half of box side wall by simply processing, therefore need not the current packaging box is carried out big transformation, simple in structure, cost is low, handsome in appearance again, Nover practical.
Description of drawings
Fig. 1 is the original opening structural representation of the utility model preferred embodiment;
Fig. 2 is the seal process scheme drawing of the utility model preferred embodiment;
Fig. 3 is the sealing state scheme drawing of the utility model preferred embodiment.
The specific embodiment
Packing box in this preferred embodiment, comprise box body 1 and sealing mechanism, box body is made up of bottom surface 2, left side wall 3, front side wall 4, right side wall 5 and rear wall 6, described sealing mechanism comprises four identical left sealing members 7, preceding sealing member 8, right sealing member 9, back sealing member 10, and each sealing member is made up of the first half of corresponding sidewall respectively.Under original opening, each sealing member and sidewall are at grade.
Because the structure of each sealing member is identical, so structure of sealing member 8 before only introducing for example, preceding sealing member 8 is provided with and reverses folding line 11, and its right-hand member is at the intersection of preceding sealing member 8 right edge and cooresponding front side wall 4, and left end is close top end on limit, preceding sealing member 8 left side.The angle that reverses folding line 11 and preceding sealing member 8 right edge is about 45 degree.
Be provided with between preceding sealing member 8 and the front side wall 4 and strengthen folding line 12.
Before the upper end of sealing member 8 be provided with and reinforce folding line 13, the left end of reinforcing the left end of folding line 13 and reversing folding line 11 overlaps, the left end that reverses folding line 11 of right-hand member and adjacent right sealing member 9 overlaps.
The centre portion of the left and right sides of preceding sealing member 8 removes a symmetrical equicrural triangle respectively, and the base of this isoceles triangle shape and side overlap, and its following waist is a curve crooked in equicrural triangle.
When the needs sealing packaging box, pin the middle part of reversing folding line 11 of adjacent left sealing member 7 and preceding sealing member 8, two sealing members folder is flat, and what make two sealing members reverses folding line 11 contacts, and its contact point is first to reverse a little 14; Other two adjacent right sealing members 9 and back sealing member 10 are pinned the middle part of respectively reversing folding line 11 equally, and two sealing members folders are flat, and what make two sealing members reverses folding line 11 contacts, and its contact point is second to reverse a little 15.Firmly make two then and reverse a relative motion, reverse a coincidence up to two, reach sealing state.At this moment, because the mutual action of each sealing member makes sealing mechanism remain on sealing state.Each sealing member upper end is outwards pulled directly by reinforcing folding line 13, can increase sealing state lower seal mechanism stability.When need opening, firmly make two to reverse a counter motion and leave, the sealing mechanism of packing box is just opened.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
