Description
Technical field
The utility model belongs to Food Packaging technology field, and in particular to a kind of paper lunch-box.
Background technology
Paper lunch-box has been widely used in catering industry, especially fast food, has the advantages that easy to use, cost is cheap,
Disposable paper lunch-box can both reclaim manufacture paper pulp, in natural environment also can fast degradation, compared to plastic cutlery box have
Standby more preferable environmental benefit.
Existing paper lunch-box is as shown in figure 1, comprising integrally formed box body 40 and lid 50, and box body 40 is by perisporium 43 and bottom
Wall 41 is formed, and lid 50 is made up of roof 51 and leg 53, is extended apical margin 45 at the top of perisporium 43, is extended in the bottom of leg 53
Go out root edge 55, fastening structure is arranged on apical margin 45 and root edge 55.Because the base material of paper lunch-box is using string to be main former
The paperboard of production is expected, by equivalent and compression molding, under conditions of equal cost, than plastic cutlery box in the deflection of paper lunch-box
Difference, i.e., it is easily deformed when diagonally applying torsion for two of paper lunch-box, or even when taking one end, in the gravity of cutlery box content
All easily deformed under effect, currently in order to improving the deflection of paper lunch-box, generally use is double-deck（It is inside and outside）The structure of cutlery box, is carried
High raw material paperboard thickness, or on leg increase flange form.First two mode undoubtedly improves the cost of paper lunch-box, weakens
Its market competitiveness, and the rectangular configuration that existing paper meal uses, in corner portion on perisporium between adjacent side plates at right angles
Arc flange is commonly made to during reason, but is limited to by paper expansion and contraction, is easily ftractureed again when flange is handled, it is above-mentioned to limit
Paper lunch-box popularization and application.
Through retrieval, Chinese patent literature CN203302515U discloses a kind of multipurpose foldable paper cutlery box, is by bottom
The left and right sides flip up to form side wall, the rear and front end of bottom flips up to form end wall, and the rear and front end of side wall is logical
Cross the first folding line and the second folding line forms two adjacent dels, the del in outside is attached on end wall.By cross cutting side
Formula suppresses folding line, can fold the first folding line and the second folding line according to the different of canteen are taken up, but still need to use thicker paperboard
To ensure deflection.It can be seen that designing the paper lunch-box that a kind of deflection is high, materials are few just turns into technical problem urgently to be resolved hurrily.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of high-stiffness, high intensity

And bottom plate, the bottom plate are in octagon, the coaming plate includes the side plate of eight pieces of head and the tail connections, the junction of the side plate and bottom plate
With folding line, it is connected between adjacent side plates to folding part, it is described that folding part is attached on side plate.
Specifically, it is described to include the first sticking part and the second sticking part, first sticking part and the second fitting to folding part
The bottom in portion and the base angle of adjacent side plates come together in the area of the octagonal vertex of bottom plate, the first sticking part and the second sticking part
It is unequal.On the one hand first sticking part is easy to wash off, while be also beneficial to top with complete would not overlap after the second sticking part doubling
Adjacent side plates are bonded to each other.
Specifically, the coaming plate, bottom plate and be integral cardboard to folding part, the top layer of the cardboard is sticked and has film layer.
Preferably, the film layer hot-melt adhesive paste of first sticking part and the second sticking part, the first sticking part and second
The film layer of the misaligned part of sticking part and adjacent side plate hot-melt adhesive paste.
Preferably, the top edge of the coaming plate has flanging.
In order to increase the intensity of bottom plate, boss can also be molded at the middle part of bottom plate.
Preferably, integral top cover is connected with the top of the side plate.
Preferably, the top cover includes roof and leg, the roof is in octagon, and the leg includes eight pieces of head and the tail
The riser of connection, the junction of the riser and roof have folding line, are connected between adjacent riser to folding portion, described pair of folded portion
It is attached on riser.
Turned edge outside preferably, the lower edge of the leg has.The shape that the flanging of box body and the outer of lid turn edge
It is mutually matched, for improving the sealing property of cutlery box with cover.
Preferably, the flanging and it is outer turn edge between be disposed with fastening structure, the fastening structure include inserted sheet and
Joint-cutting.Take for convenience, generally turned edge upper arrangement inserted sheet outside, and joint-cutting position is set on flanging.But inserted sheet can also be set
In on flanging, joint-cutting is on outer turn edge.
Beneficial effect：The utility model by using octagon bottom plate and eight blocks of side plates structure, compared to existing rectangle
Paper lunch-box possesses following substantial advance：
1. under conditions of using equal thickness paperboard, such as 230g ~ 260g paper, possesses higher deflection than rectangle paper lunch-box.
Similarly under same stiffness requirement, paper lunch-box of the present utility model can than rectangle paper lunch-box use thinner paperboard, possess
The significantly stronger market competitiveness；
2. intensity is significantly increased, the polygonized structure that octagon bottom is formed with eight side plates, compared to existing rectangle
Paper lunch-box, angle are changed into obtuse angle from right angle, and the mutual binding character of each several part is more preferable, makes paper lunch-box as an entirety, its intensity
It is more preferable with hardness；
3. flange processing is easier during manufacture, because the junction of top plate is obtuse angle, in flange, deflection is small, no
It is easy to crack；
4. due to adding side number, the knuckle of adjacent surface is smaller during manufacture, and damage rate accordingly reduces, and product yield improves,
It is high to manufacture economy；
Except the technical problem of above-described the utility model solution, form the technical characteristic of technical scheme and by these
Caused by the technical characteristic of technical scheme outside advantage, below in conjunction with the accompanying drawing in the utility model embodiment, to this practicality
