CN205010616U - Special soft plastics turnover case of tobacco - Google Patents

Abstract

The utility model discloses a special soft plastics turnover case of tobacco, it is folding by soft plastics honeycomb board, the welding forms, the apron that has the box and connect both sides about the box, be provided with folding indentation between box and the apron, since soft plastics honeycomb board in than the soft plastics hollow plate better bearing capacity has, can prolong the life of turnover case, folding indentation is corrugated continuous curve or some trace, because the inside and outside both sides at folding position are tensile and compression position height is uneven, can increase the intensity at folding position on the one hand, make the turnover case have good compressive capacity, folding position also is difficult to the fracture, can improve the life of product, on the other hand, can strengthen the elasticity at folding position, when the turnover case is folding, the apron can be bounce automatically, convenient range upon range of stacking, simultaneously when the dress cigarette is unpacked to the turnover case, the apron also can be bounce automatically, make things convenient for the cigarette vanning.

Description

One grows tobacco special flexible plastic Turnover Box

Technical field

The utility model relates to a kind of packing chest, particularly one to grow tobacco special flexible plastic Turnover Box.

Background technology

Flexible plastic Turnover Box has long service life, waterproof, the advantages such as protection against the tide are widely used in tobacco transhipment, logistics field, current flexible plastic Turnover Box is made up of PP hollow sheeting, PP hollow sheeting is made up of sandwich layer and the surface layer being affixed on sandwich layer both sides, although the shape of sandwich layer has a lot, if publication number cross section disclosed in the patent documentation of CN102152504A is the sandwich layer of square waveform, if publication number cross section disclosed in the patent documentation of CN104015449A is the sandwich layer of V-arrangement, if publication number cross section disclosed in the patent documentation of CN203277338U is the sandwich layer etc. of corrugated, but this kind of flexible plastic hollow sheeting has a common feature, that is exactly sandwich layer is strip, bearing capacity is relatively weak, the Turnover Box of goods is housed when layer code is stacked, the easy extrusion of Turnover Box of lower floor, even break, service life is still shorter.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of tobacco of long service life special flexible plastic Turnover Box.

The utility model solves the technical scheme that its technical matters adopts:

One grows tobacco special flexible plastic Turnover Box, and, welding folding by flexible plastic honeycomb boards is formed, has casing and is connected to the cover plate of the upper and lower both sides of casing, be provided with folding impression between described casing and described cover plate.

Described folding impression is corrugated continuous curve or some trace.

Described flexible plastic honeycomb boards is made up of sandwich layer and the surface layer being affixed on sandwich layer both sides, and described sandwich layer is provided with the vertical hole of some and described surface layer, and described hole is vertical with described surface layer.

The cross-sectional plane in described hole is regular hexagon or circle.

The beneficial effects of the utility model are: Turnover Box of the present utility model is folded by flexible plastic honeycomb boards, welding is formed, because flexible plastic honeycomb boards has better bearing capacity than flexible plastic hollow sheeting, the service life of Turnover Box can be extended, folding impression is corrugated continuous curve or some trace, because two side stretchings inside and outside folding position and compression position are uneven, the intensity at folding position can be increased on the one hand, Turnover Box is made to have good pressure resistance, folding position is also not easy fracture, the service life of product can be improved, on the other hand, the elasticity at folding position can be strengthened, when Turnover Box folding, cover plate can be upspring automatically, facilitate ranked and stacked pile, simultaneously when Turnover Box unpacks dress cigarette, cover plate also can be upspring automatically, cigarette is facilitated to case.

Detailed description of the invention

Referring to figs. 1 through Fig. 6, one grows tobacco special flexible plastic Turnover Box, is formed by the cutting of flexible plastic honeycomb boards, folding, welding, has casing and is connected to the cover plate of the upper and lower both sides of casing, be provided with folding impression between described casing and described cover plate.The structure of flexible plastic honeycomb boards is as publication number PVC honeycomb sheet material disclosed in the patent documentation of CN203919888U, as publication number real core honeycomb boards disclosed in the patent documentation of CN101619801B, as publication number flexible plastic honeycomb boards etc. disclosed in CN102717508A patent documentation, the difference of flexible plastic honeycomb boards and plastic hollow boards is, sandwich layer in plastic hollow boards is strip, and the sandwich layer in flexible plastic honeycomb boards is netted in what interlock, flexible plastic honeycomb boards is relative to flexible plastic hollow sheeting, there is better bearing capacity, the flexible plastic Turnover Box be made up of flexible plastic honeycomb boards has good bearing capacity naturally, the service life of Turnover Box can be extended.

Described folding impression can be corrugated continuous curve as shown in Figure 2, also can for corrugated some trace (being commonly called as S curve) as shown in Figure 1, and the present embodiment illustrates for rectangular flexible plastic Turnover Box.

The expansion drawing of oblong flexible plastic Turnover Box is as Fig. 1, shown in Fig. 2, by leading flank 1, trailing flank 2, left surface 3, right flank 4 form casing and be connected to leading flank 1, trailing flank 2, left surface 3, the front upper cover plate 5 at right flank about 4 two ends, rear upper cover plate 6, upper left cover plate 7, upper right cover plate 8, front lower cover 11, rear lower cover 10, lower-left cover plate 12, cover plate 13 8 cover plates in bottom right are formed, and the left side of left surface 3 and the right side welding of trailing flank 2 form square casing, leading flank 1 and front upper cover plate 5, between front lower cover 11, trailing flank 2 and rear upper cover plate 6, between rear lower cover 10, left surface 3 and upper left cover plate 7, between lower-left cover plate 12, right flank 4 and upper right cover plate 8, folding impression a is provided with between bottom right cover plate 13, be uneven due to two side stretchings inside and outside folding position and compression position, can increase the intensity at folding position on the one hand, make Turnover Box have good pressure resistance, folding position is also not easy fracture, the service life of product can be improved, on the other hand, the elasticity at folding position can be strengthened, when Turnover Box folding, cover plate can be upspring automatically, facilitates ranked and stacked pile.

As shown in Figures 3 to 6, described flexible plastic honeycomb boards is made up of sandwich layer 14 and the surface layer 15 being affixed on sandwich layer 14 both sides, sandwich layer 14 and surface layer 15 are made up of flexible plastics such as PE, PP, PS, PMMA, PVC, Nylon, PC, PU, PTFE, PET, PETE, described sandwich layer 14 is provided with the vertical hole 16 of some and described surface layer 15, the cross-sectional plane in hole can be regular hexagon as shown in Figure 3, also can be circle as shown in Figure 4.For breakthrough form hole 16 as shown in Figure 5, sandwich layer 14 can adopt the larger core material of a slice thickness through cutting formation, for depression shape hole 16 as shown in Figure 6, the method of plastic uptake or extrusion vacuum forming can be adopted to be formed, and the method for making of flexible plastic honeycomb boards can see publication number technical scheme disclosed in the patent document of CN102717508A.
