Description
Technical field
It the utility model is related to container, and in particular to folding carton.
Background technology
When in use, side plate relative will deploy upright, four pieces of side plates interlockings, so as to form relative closure to existing folding carton
Holding freight is carried out in space, and after goods empties, casing is needed to be recovered, and in order to which bigizationner is cost-effective, box side is entered
Row folds, and make it that more casing recovery can be accommodated in equal space.To be easy to clean in removal process, particularly work as
Folding carton be used for load vegetables and fruits it is fresh wait food when, cleaned after use particularly important.Meanwhile casing should will ensure in use
Safe and reliable in the goods of its loading, side plate wants unblock and the folding of simple and fast when goods empties in case again.
Existing folding carton patent, such as the folding disclosed in US7100786B2, casing agent structure by thin-walled and
The arrangement composition of its surface reinforcement, for base hinge installation site because elasticity installation needs, its structure is single and weak.Base
There is the unclosed cavity of more shaping after shaping, its depressed area of grid ribs is easy to entrapped contaminants, efficiency in Rapid Cleaning
It is low.Especially in base safe edge position, due to needing the needs with the hinge assemblies of side plate and base shaping, its base has greatly
Amount and deeper cavity, this region can flow into substantial amounts of sewage when cleaning, be not easy to discharge, easy breed bacteria.
In addition, this thin wall construction is single in the formal ability of bending resistance resistance to compression, especially in side plate and base articulated section
Position, side plate main and hinge are connected by single thin-walled, especially in the larger goods of casing carrying density, base inner surface by
Pressure and to lower recess, side plate now is because its hinge is hinged with base safe edge, and safe edge can inwardly lie prone with base sunken inside, side
Plate is also bent by the traction of safe edge to inner side and deformation downwards at random close to hinge side.Therefore, in existing folding carton, side plate
Nearly hinge position is when its carrying increases, it is impossible to the deformation that base safe edge is inwardly lain prone is resisted, and in make it that cabinet base is easier
Depression, causes and is lain prone in base safe edge and further result in side intra-plate deformation.When using its multi-layer box stacking, the goods on upper strata
It then can deform with base thin-walled and be pressurized with goods in casing in its lower section, it is hidden safety to be present to goods to a certain extent
Suffer from, and during casing reuse, be easily caused fatigue damage using stress deformation in the frequently high and low temperature environment of casing, shorten
The service life of casing.

Figure 17-19 shows the structure chart of a variation of the folding carton shown in Fig. 9.The variation and the folding shown in Fig. 9
The difference of case is, the bite shown in bite 401 and Fig. 9 of the bottom of side plate 40 of the folding carton 101 of the present embodiment
301 is different, and remaining is identical, will not be described in detail herein.As shown in figure 18, the bite 401 of side plate 40 is also included from bite body
The limiting section 401a extended.Limiting section 401a is arranged so that in the state of side plate folds limiting section 401a is stung with side plate
Conjunction portion coordinates, to hinder side plate bite 401 to depart from base along towards the direction inside folding carton.It should be understood that can also
By being sized for more greatly to realize and above-mentioned limiting section 401a identical functions for bite 401.
Figure 20-21 shows the structure chart of another variation of the folding carton shown in Fig. 9.The variation and the folding shown in Fig. 9
The difference of stacked box is, the connection shown in connecting portion 502 and Fig. 9 of the bottom of side plate 50 of the folding carton 102 of the present embodiment
Portion 302 is different, and base 60 is provided with the structure matched with connecting portion, and remaining is identical, will not be described in detail herein.As Figure 20-21 institute
Show, the connecting portion 502 of side plate 50 also includes the spacing preiection 502a extended from the side of connecting portion.The structure and figure of base 60
Understructure shown in 9 is essentially identical, only difference is that and is set in cavity in the opening position corresponding with spacing preiection 502a
Fluted 601, remaining is identical, will not be described in detail herein.In the state of side plate folding, spacing preiection 502a and base groove 601
Coordinate, to hinder side plate to depart from base along towards the direction inside folding carton.
It should be understood that can also by other means or structure hinders side plate along being taken off towards the direction inside folding carton
From base.
Figure 22 shows the partial perspective view of folding carton, and which part cutting is to show internal structure.As shown in figure 22, side plate
The extension on tri- directions of x, y and z is corresponding with base.X direction of the hinge along long side plate is set.Side plate rib, i.e. cavity
There is certain thickness in the vertical direction y-axis along hinge setting direction.Base rib (i.e. cavity) is set along x directions
Put.Base has the cargo carrying face of swept area along x, z-axis direction arrangement.Side plate has corresponding branch with the hinged place of base
Point, side plate fulcrum A, B are offset up in Z axis corresponding to base fulcrum A, B, form lever, with confrontation because base carries at present
Fall into side plate inwardly to offset with base hinged place, especially form the Part I that base is strengthened.
Side plate lower edge sets rib and base rib to be collectively forming the Part II of base reinforcing.It is particularly in hinge
The side plate rib of socket part position and base rib, hinge point is added in x, y, the ability of anti-deformation (base on z-axis direction
Stress carry when, when base safe edge y-axis negative direction and base are sunk by bearing area base safe edge by be forced to z-axis to it is inclined
Move).
In addition, comparing other kinds of cavity, the cavity structure of closure make it that the non-deformability of side plate and base is big
It is big to improve.The base safe edge using the cavity of different cross section is shown respectively in Figure 23 a-23b, when base carries, relative to x, z side
To along y-axis to deformation schematic diagram.Figure 23 a are inverted U style of opening die cavity figure, and Figure 23 b are enclosed type die cavity.In base safe edge two
In the case of end is relatively fixed and applies certain pressure at middle part, the protective edge structure in two kinds of different die cavity sections has different bending resistances
Ability.At the same pressure, the deflection of opening die cavity reaches 50, and the deflection of enclosed type die cavity only has 46.It is apparent that
Enclosed type die cavity safe edge has more preferable ability of anti-deformation.
Base safe edge is shown respectively when base pressure-bearing is sunk in Figure 23 c and Figure 23 d, and local torsion is showed on yz sections
Bent schematic diagram.When base sink, compared to opening die cavity, the angle of base safe edge section and y-axis is in enclosed type die cavity
Reduction trend, i.e. a1>a2.As can be seen here, the base safe edge die cavity of closing is base safe edge with more confrontation twist distortion ability
Distortion.
In summary, enclosed pedestal safe edge die cavity is effectively improved base deformation, so as to lift the bearing capacity of base.
