Abstract

The utility model discloses a composite corrugated packing box. A longitudinal skeleton (1) which is provided with distributed diagonal lines is arranged between a corrugated layer and an external surface layer of a box body of the corrugated packing box, a fibrous membrane coating layer (2) is arranged at wavy gaps of the corrugated layer, and a spray plastic waterproof membrane (3) is arranged on the external surface of the box body. The compression resistance and the shock resistance of the composite corrugated packing box are better than that of the existing corrugated boxes, and the utility model can be used for administration and has the advantages of moisture resistance, wide material origin, lower price and capability of packing heavy articles.

Description

Composite corrugated packing chest

The utility model relates to a kind of composite corrugated packing chest.

Corrugated case is a kind of widely used packing chest, is used for the packing of product, is convenient to stack, stores, transports, and inner package can avoid storing the damage in the transportation.The material source of making corrugated case is wide, cost is cheap relatively.But it is once using outward appearance just yielding, so this packing chest is often only done disposable use, its use cost is on the contrary than nonexpondable packing chest height, corrugated case resistance to compression simultaneously, impact resistance are relatively poor, and it only limits to packings general lighter, less article and uses, and stack to be subjected to the packing material weight limits unsuitable too high in storing, corrugated case is afraid of tide, is afraid of to wet in addition, once humidity, resistance to compression, shock resistance descend significantly, lose value of service.

The purpose of this utility model provides a kind of resistance to compression, impact resistance and is better than existing corrugated case, can repeated usage, and moistureproof damp-proof composite corrugated packing chest.

Composite corrugated packing chest is made up of fluting board, skeleton, tunica fibrosa, membrane waterproofing, skeleton vertical and that diagonal line is arranged is set between the corrugated layer of fluting board and the uppermost layer, the curved surface gap of corrugated layer has the tunica fibrosa that adhesives is made base-material, and the uppermost layer plastic-blasting of case is coated with rete.

After adopting such structure, be clipped in the middle skeleton longitudinally of fluting board, the casing pressure resistance is increased substantially, the tunica fibrosa at corrugated layer curved surface place has been strengthened the intensity of corrugated layer, and the wall box impact resistance is improved.The plastic-blasting membrane waterproofing of casing uppermost layer makes water and moisture not advance the papery layer of casing.The corrugated packaging box of compound type, the characteristics that the original material source of corrugation case is wide, price is lower had both been kept, but packed and transported is arranged than heavy articles, repeated use, damp proof, damp-proof advantage again, this packing chest can enlarge the range of use of original packing chest, reduces the connection with wrapping of piece Packing Fee.

Description of drawings:

Fig. 1 is a block diagram of the present utility model.

Fig. 2 is Figure 1A-A ' face cutaway view.

Composite corrugated packing chest shown in Figure 1, four side external surfaces are to be made by the bamboo and wood material with the frame [1] that the intersection diagonal line is arranged vertically, the common strawboard of paperboard grade (stock), corrugation technology routinely is rolled into waveform, brushing is the cloth and the cotton fiber mixed coating of base-material with the resin glue on fluting board [2] corrugated suface, adhere to the fleece of one deck curing on the dried back corrugated suface of making an uproar of coating and film, the uppermost layer plastic-blasting of outer paper forms one deck membrane waterproofing [3].In producing the boxboard process, bonding with the program up and down of overlay paper, skeleton, fluting board, internal layer paper, be pressed into four sidewalls and on the plate of going to the bottom, the flanging place between plate and the plate extrudes broken line with edging machine, routinely bookbinding or case.

Embodiment uses that case is molded makes one-time formed composite corrugated packing chest, on the case internal mold with ordinary case paperboard, contain tunica fibrosa fluting board, skeleton, with the program of plastic-blasting waterproof uppermost layer paper adhesive bonds from level to level, hot-forming with the external mold that skeleton groove is arranged again.

Claims

1, a kind of composite corrugated packing chest is made up of fluting board, skeleton, tunica fibrosa coating, it is characterized in that: also have skeleton [1] vertical and that diagonal line is arranged between the corrugated layer of fluting board and the uppermost layer, there is tunica fibrosa coating [2] the curved surface gap of corrugated layer.

2, composite corrugated packing chest as claimed in claim 1 is characterized in that: box outer surface has plastic-blasting film waterproof layer [3].

3, composite corrugated packing chest as claimed in claim 1 or 2 is characterized in that four sidewalls and the end are continuous integral body.
