In the middle of one or more embodiments of the present utility model, this paper-plastic stick sheet material include PE outer layer, paper layer and
PE internal layer.
Furthermore, the utility model proposes a kind of fresh-keeping type liquid milk rooftop box of protection, it is by above-mentioned rooftop box blank folding
Folded heat-sealing is formed.
Compared with prior art, its advantageous exists this utility model: the technology sealed again after using overlap edge opisthotonos
Improve to avoid contacting of trimming and milk, it is ensured that the fresh and local flavor of milk is constant, also extends the shelf life of milk.This
The technical construction of utility model is simple and ingenious, and implementation cost is cheap, solves the fresh-keeping problem of liquid milk well, from technology
In property, practicality and economy the most outstanding, be suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is the perspective view of liquid milk rooftop box in the middle of prior art.
Fig. 2 is the A-A direction sectional view (locally) of Fig. 1.
Fig. 3 is the structural representation of fresh-keeping type liquid milk rooftop box blank of the present utility model.
Fig. 4 is the scrap (bridge) opisthotonos heat-sealing structure schematic diagram of fresh-keeping type liquid milk rooftop box of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the application scheme is further described:
See attached Fig. 1 and 2, the overlapping edges of existing liquid milk rooftop box be all use identical with common dixie cup direct
Scrap (bridge) hot edge seal, in box, the paper end face of edge sealing part is immersed in milk-based liq, and the material in paper can be seeped into milk at leisure
In, easily making paper taste on milk band, local flavor reduces, and even results in the drawback of milk modification.
To this, the utility model proposes preferably solution:
A kind of rooftop box blank, it includes the main body cut by paper-plastic stick sheet material, and paper-plastic stick sheet material includes PE
Outer layer, paper layer and PE internal layer, this main body longitudinal folding is divided into some adjacent faces (1,2,3,4) by multiple, this main body each
Face (1,2,3,4) collapsible connection is to form rooftop box, and the left side of this main body or right side are provided with side edge fit, and this side joint limit is used for
With the face inwall overlap joint heat-sealing of main body opposite side, this side joint limit 5 includes folding first 5b connected and second 5a, and this is second years old
Portion 5a is made outside it outer wall with first 5b connect by the edge fold of this first 5b, make inside it with main body opposite side
Face inwall connects, and then seals, and the thickness on this side joint limit 5 is 1/2nd of body thickness, to make the of this side joint limit
Thickness after one 5b and second 5a folds is equal with body thickness, this main body can fold formation have a pair main box face 1,
3 and the rooftop box of a pair end panel 2,4, this main box face 1,3 and end panel 2,4 are respectively provided with some laterally folded to make this master
Box face and end panel can fold the formation roof of rooftop box, box body and bottom, and the upper end in this main box face is provided with termination limit 11,31,
The upper end-face edge of this end panel 2,4 is less than this termination limit 11,31, and the two ends on this termination limit 11,31 are fillet design.
Seeing accompanying drawing 3 and 4, concrete, the main body in the middle of this enforcement includes by some longitudinal folding main boxes being divided into
Face 1,3, end panel 2,4, and this main box face 1,3 are terminated limits 11,31 by some laterally folded being divided into respectively, main deck 12,
32, the 13,33 and first bottom surface, positive side 14,34, in this end panel 2,4 is divided into by some laterally folded, inclined foldings respectively
Concave surface 22,42, end face the 23,43 and second bottom surface 24,44, wherein, this respective top of inner concave 22,42 be provided with equivalent limit 21,
41, the top edge alignment on this equivalent limit 21,41 and the top edge less than this termination limit 11,31, so at termination limit 11,31 and folding
Not havinging clout spill-over and cause the situation of boundary zone burr when closing limit 21,41 heat-sealing, this second bottom surface 24 connects has the end even
Edge fit 25, this connection limit, end 25 heat-sealing for each of bottom is fixed；
This main box face 1 connects side edge fit 5, and this side joint limit 5 is for overlapping heat-sealing, this side joint limit 5 with end panel 4 inwall
Form by longitudinal folding 51 divisions including folding first 5b connected and second 5a(), this second 5a is longitudinal folding along this
51 fold and make outside it outer wall with first 5b connect, and make and connecting with end panel 4 inwall inside it, then seal, should
The thickness on side joint limit 5 is 1/2nd of body thickness, with the thickness after making first 5b and second 5a on this side joint limit 5 fold
Spend equal with body thickness
A kind of fresh-keeping type liquid milk rooftop box, it is folded heat-sealing by above-mentioned rooftop box blank and is formed, at heat sealing
The technique improvement sealed again after have employed overlap edge (i.e. side joint limit 5) opisthotonos, is to allow PE internal layer contact with liquid milk, so all the time
It is avoided that the contacting of trimming and milk in the middle of conventional art, make the material in paper to be seeped at leisure in milk, easily make milk
Paper taste on band, local flavor reduces, even results in the drawback of milk modification, it is ensured that the fresh and local flavor of milk is constant, also extends cattle
The shelf life of milk.
Above-mentioned preferred implementation should be regarded as the illustration of the application scheme embodiment, all and the application scheme thunder
Deduce with, approximation or the technology made based on this, replace, improvement etc., be regarded as the protection domain of this patent.
