Abstract

The utility model relates to a paper zip-top can. Packing materials for preparing the zip-top can comprise an outer coating layer, a raw paper layer, composite layers, blocking layers, bonding layers and innermost layers from the outside to the inside, cutting roll rims are arranged at the two ends of the packing materials, and the innermost layers of the cutting roll rims are in hot sealing and are spliced. The paper zip-top can has the beneficial effects that a lapping part is directly contacted with the innermost layers of the packing materials and is sealed by heating without adhesive tapes, so that the raw materials for production and a tape striping device are saved, correspondingly, the process steps needing to be adopted by the production of a packed product can be reduced, and the time of the packing process is shortened due to the fewer work procedures.

Description

A kind of paper pop-top

Technical field

The utility model relates to a kind of packing container, relates in particular to a kind of paper pop-top.

Background technology

Aseptic packaging (Aseptic packaging) is a kind of work programme that prevents germ entering packing of product in pouring process and after the can; Be meant the sterilization of liquid food process short time before packing of pack; Then under aseptic condition promptly under all aseptic condition of packing material, packed article, packing auxiliary appliance, in aseptic environments, fill a kind of packing technique with involution.Product after the aseptic packaging; The germ, toxin and the germ that do not contain easy breeding; Do not need anti fouling composition; And packing container can prevent the secondary invasion of bacterium or germ, and its special protection performance is more effectively slowed down the unnecessary variation of product because of producing with air, other gas, peculiar smell and light mutual action.Even under the condition of not having refrigeration, product still possibly preserved considerable time.At present the packing container material in the sterile filling is processed by laminate wrapping material, and this laminate wrapping material comprises by the 3-5 layer material lamination holistic belt packing that are composited; Not easily separated; Wherein comprise at least: play supporting layer firm and the reinforcement packing container, keep liquid quality and the thermoplastic inner layer of carrying out heat sealing, between supporting layer and innermost layer property innermost layer, isolation layer is arranged; Starvation and sunlight and prevent that the product taste runs off, the conductive layer when also being high-frequency induction simultaneously.Shown in Figure 1, packing are processed by six layer materials, are followed successively by by (from top to bottom) outward inward: uppermost layer 11, supporting layer 12, the first viscous layers 13, isolation layer 14, the second viscous layers 15, innermost layer 16.They are inseparable entire package material through being composited, left and right two vertical end structures are symmetry fully.The belt packing; Further be wound in the rolling packing, in the beverage products package production, the rolling packing trail and become band; Banded packing are shaped to ellipticity on working direction; The ellipticity packing further are shaped to the cylindrical packages material, and dual-side is by the vertical envelope of longitudinal lap joint, and form pipe.Pipe is in the horizontal sealing of one of which end, and fills required content, and the residue of pipe is held corresponding horizontal sealing, and cutting knife cuts the horizontal sealing zone, to form single packing container.Form above-mentioned packing container through cutting then, must guarantee tight vertical envelope and horizontal sealing, thereby prevent the secondary invasion of bacterium or germ.Generally be the width that cuts packing according to the capacity of packing container, therefore, undressed packing, two vertical limits, promptly an end 1-1 and other end 1-2 are cutting edge.In sterile filling, packing directly overlap when forming vertical the envelope, can expose to the content of finished product packing.And packing supporting layer 12 contains absorbing material, and like paper or cardboard, content can be inhaled in the packing, and is softening thereby packing are corroded, even danger such as leakage occurs.In addition, in aseptic packaging, isolation layer 14 contains metal, and like aluminium foil, this does not have the cutting edge of protection not contact in inclusion, must protect with some mode, because metal pair food has negative effect.

Shown in Figure 2; A kind of known method for the inclusion direct contact that prevents cutting edge and packing container; It is to use bar shaped adhesive tape 10 longitudinally; Couple together an end 1-1 and the other end 1-2 of lap-joint, cutting edge is capped simultaneously, and this plastic tape moves forward, crosses on cutting edge and the thermoplastic inner layer 16 of sealing at packing when forming pipe.Adhesive tape 10 adopts thermoplastic material, like PP (poly-vinyl) bar, it can be fixed on the packing through thermosealed mode.Its operating process is following usually: the rolling packing are stretched and are split in the process of strip material, paste adhesive tape 10 on the 1-1 end internal layer surface through blowing hot-air, and the belt packing that have adhesive tape continue to move ahead; After the disinfectant sterilization of sterilization chamber; Be shaped to ellipticity through former, the ellipticity packing further are shaped to the cylindrical packages material through former, and dual-side is by longitudinal lap joint; An end that has adhesive tape 10 is in the lining; This moment is again through blowing hot-air heating, through the pressing of pressure, and by for example embedding pressure or roll-in mode realize that two mating surfaces layers are softening each other, fusing, bonding, cooling and solidify; It is fused together, and form pipe.Pipe through electronic heating and horizontal sealing, and is filled required content at the one of which end, with the residue end of pipe correspondingly through electronic heating and horizontal sealing is cut the horizontal sealing zone through cutting knife then, to form single packing container.

Therefore in above-mentioned sterile filling device, must be attached to adhesive tape 10 on the packing by special strip sticking device and heating, blowing hot-air device.Corresponding, when each start moves, long period preheating said apparatus must be provided.In addition, packing container will be the twice of packing container remainder at the thickness of vertical wire area, make that the regional transition of vertical envelope is level and smooth inadequately, not only influence attractive in appearance but also be unfavorable for automatic boxing and the carrying on the manufacturing line.

The utility model content

The purpose of the utility model provides a kind of simple and effective vertical envelope mode to address the above problem.

The technical scheme of the utility model is: a kind of paper pop-top; The packing that constitute this pop can comprise external coating, original paper layer, composite bed from outside to inside successively; Barrier layere; Tack coat and innermost layer, vertical two ends of described packing are provided with the cutting crimping, described cutting crimping innermost layer heat-sealing splicing.

As the further improvement of utility model, described cutting crimping comprises tack coat and innermost layer successively.

As the further improvement of utility model, described cutting crimping comprises composite bed successively, barrier layere, tack coat and innermost layer.

As the further improvement of utility model, the cutting crimping at said packing two ends is and is symmetrical set.

The beneficial effect of the utility model is: the utility model lap-joint is by packing innermost layer direct contact; Through add the heat-sealing with; Need not adhesive tape; Saved production raw MAT'L and strip sticking device, reduced accordingly accomplish packaging product production the number of the processing step that must take, less operation shortened the time of technology of the package.
