Description

Semi-fluid build polymer packaging carton casing

Technical field

The utility model relates to a kind of Packaging Box, specifically is the accumulating packing chest casing that the semi-fluid three-dimensional polymer uses.

Background technology

Middle mol wt semi-fluid three-dimensional polymer (as polyisobutene) is a kind of freak oil that are widely used in industry-by-industries such as food, medicine, needs be transported to downstream producer through just dispatching from the factory after the packing.Because cardboard has plastic modeling structure, the hard and soft protective value that has both, can propagate beautify commodity, packing cost comparatively cheap, be easy to recycle, plurality of advantages such as the storage transport economic specific property is good, thereby as the material of the preferential employing of Packaging Box of poly-mer.

Yet,, be bonded in the top layer cardboard of common corruggted wrapping case easily and be difficult to and separate because this base polymer has stronger viscosity; For this reason, Chinese patent file (patent No. ZL200720108631.0) discloses a kind of Packaging Box, has successfully solved this problem.Its main characteristics is to be equipped with one deck parting paper in the paperboard surface that constitutes cabinets cavity, and this parting paper is compound to paperboard surface by adhesives, and makes the carton after folding have cooresponding strength and stiffness by suitable folding cardboard structure.Through facts have proved that above-mentioned carton can correspond to actual needs.Yet, find still have the carton of multiple foldable structure can satisfy operating needs behind contriver's in-depth study.

The utility model content

The purpose of this utility model provides a kind of polymer packaging carton casing, and this carton casing should be able to satisfy the polymer packaging requirement, has effective, easy to use, the lower-cost characteristics of packing.

The technical scheme that the utility model provides is: semi-fluid build polymer packaging carton casing, to make by corrugated board, and described corrugated board has one deck parting paper towards the surface recombination of cabinets cavity; It is characterized in that this casing is the rectangular cylinder of the end face opening that is folded to form with corrugated board; Wherein a direct part as casing opening edge edge is distinguished in the upper edge of two sidewalls face to face, the two ends, the left and right sides of each sidewall respectively along and the boundary line of adjacent wall turnover 90 degree after be coated on adjacent wall outside face and and the outside face of adjacent wall between form lap seam, the upper part of described adjacent wall be along the line of aforementioned two sidewall upper edges toward the outer direction rotation of case turnover 180 degree after bag pressures the turnover face at the two ends, the left and right sides of aforementioned lateral wall; Be held fixing after the fore-end of this turnover face is spent toward same hand of rotation turnover 180 once more in the aforementioned lap seam of insertion.

The width that is coated on the adjacent wall outer surface part at two ends, the described sidewall left and right sides is less than 1/2nd of adjacent wall width.

The beneficial effects of the utility model are: owing to the foldable structure of the designed uniqueness of the utility model, obviously improved the strength and stiffness of body structure, enabled to satisfy fully the requirement of polyisobutene packed and transported; And this casing is folded to form by plate shaped corrugated board fully, only need add the flushing technology in preceding road, need not supporting bookbinding parts, and operation obtains simplifying, and the succinct rule of the display pattern of casing are just, and cost also is minimized.In addition and since the surface of internal cavity of carton compound one deck parting paper (poly-mer then separates easily with parting paper), defective that this has just been avoided poly-mer and Packaging Box to be difficult to separate fully then can not separated when the packing accumulating; And need not be again when the packing of product with special messenger's folding film or parting paper and in carton the operation of place mat, production efficiency improves greatly.

The specific embodiment

As seen from the figure: described semi-fluid build polymer packaging carton comprises casing and case lid, and casing and case lid are made by corrugated board, and corrugated board has one deck parting paper towards the surface recombination of cabinets cavity; This parting paper is compound to paperboard surface by adhesives, sticks together to prevent poly-mer and carton.Its process is exactly with the parting paper coated with adhesive, through making it to be bonded in the paperboard surface that constitutes carton after the heating, forms the product of cardboard and parting paper unification.Described parting paper is the available craft paper (conventional products) that scribbles silicone oil usually; Described adhesives buyable, it adds thermal bonding technology also is common process.

In the utility model, the rectangular cylinder of the end face opening that described casing is folded to form by corrugated board; Wherein the upper edge 1-2 of two sidewalls 1 face to face distinguishes a direct part as casing opening edge edge, the two ends, the left and right sides of each sidewall (left end 1-1 and right-hand member 1-3) respectively along and boundary line 3 turnover 90 degree of adjacent wall after be coated on adjacent wall 2 outside face and and the outside face of adjacent wall between form lap seam 5, the turnover face 2-1 of the upper part of each adjacent wall two ends, the left and right sides (bag pressure the left end 1-1 of a sidewall and the right-hand member 1-3 of another sidewall simultaneously) that outer direction rotation turnover 180 degree back bag pressures aforementioned lateral wall along the line of aforementioned two sidewall upper edges toward case are held fixing in the aforementioned lap seam 5 of insertion after the fore-end 2-11 of this turnover face spends toward same hand of rotation turnover 180 once more.

The width that is coated on the adjacent wall outer surface part of described sidewall left and right sides two ends 1-1 is less than 1/2nd of adjacent wall width; Like this, two ends, the left and right sides 1-1 that is coated on the sidewall 1 on the adjacent wall outside face can be not overlapping, and the wall thickness of casing is unlikely increase.

The case lid of Fig. 4-shown in Figure 6 can supporting aforesaid casing; Earlier flat cardboard punching out is become structure shown in Figure 5 during making, press Fig. 6 then and fold and get final product.Nature, case lid that also can supporting other foldable structure.

In addition, still it should be noted that: the fold line the when dotted line among the figure is all represented to fold.

Corrugated cardboard box mainly adopts honeycomb paper core to make, and honeycomb paper core thickness is 10-150mm, and the honeycomb cardboard thickness of making is 12-42mm; The cardboard of honeycomb paper core has light weight, and intensity is big, the rigidity height, has the buffering vibration isolation, and the excellent properties of insulation and sound insulation can be fire-retardant, moistureproof, waterproof, mildew-resistant, and cost is low.It, is significant to preserving the ecological environment to substitute timber, clay brick and highly foamed polystyrene (EPS) as sheet material, framing member or packing material.
