Abstract

The utility model discloses a foldable packing box which is composed of two mutually symmetrical large lateral surfaces, two mutually symmetrical small lateral surfaces, a bottom plate and a sealing cap, wherein a waist shaft and a bottom shaft are respectively and transversally arranged on the middle part of each large lateral surface and the connecting point of the large lateral surface and the bottom plate, which can cause the large lateral surface to be inflected and folded inward. A turning button is arranged at each of four upper corners of the foldable packing box, the small lateral surfaces can rotate by 90 DEG inward and upward, and the large lateral surfaces can be folded inward to finish folding. Raw materials of the utility model have no grass and wood components, no fibre sheds in the process of rotation, the raw materials can not mildew because of wetting, and thus, the environment can not be polluted. The utility model can be used for multiple times, and thus, the cost is not higher than that of a paper box; the foldable packing box is stored in a folded mode after each packing task is completed, and the volume is 1/4 of that of an expanded packing box; the pressure resistance and the impact resistance of the foldable packing box are both higher than that of a paper box.

Description

Foldable packing box

The utility model relate to a kind of the transportation circular flow in folding extranal packing box.

Present employed extranal packing box mostly is carton, crate, bamboo basket.Along with expanding economy, Natural Resources in China is day by day nervous, and paper pulp, timber price are in rising trend in recent years.The service life of carton is very short, and bamboo, willow basket all become rubbish after finishing the packing task, and the reclaiming process of carton is also wanted several links.

For prolonging the service life of extranal packing box, be convenient to carry, dwindle and take up an area of the space, the utility model provides a kind of transportation, folding incorporate extranal packing box, and its purpose is to reduce the consumption of natural resources, does not increase packing cost simultaneously again, once making, all very convenient in each use.

The utility model Collapsible container, form by two symmetrical big sides, two little sides, a base plate and a capping, at the middle part of each big side with the base plate connecting place waist axle 1b and lower shaft 2b are housed laterally respectively, can make big side curve inwardly, fold (see figure 1); A break-in button respectively is equipped with at the place, angle on four of case, can make little side inwardly, upwards rotate 90 °, and make the inside doubling in big side, finishes folding.The big side of the utility model is by up and down two convex-concaves engagements, and waist axle 1b is contained in slice (or sheet) down and protrudes center of (or recessed) part, and is positioned on the outerplanar of big side (seeing Fig. 2, Fig. 3).Sheet and base plate are also with the convex-concave engagement under the big side, and lower shaft 2b is contained in down the center (Fig. 4, Fig. 5, Fig. 6, Fig. 7) of sheet projection and base plate bossing.The thickness of following sheet projection and base plate projection equates with following sheet thickness.Respectively there is an aperture 3 at the place, last angle of big side last slice, is used to adorn the thin axle 8 of break-in button.Each break-in button is formed (seeing Figure 14) by orthogonal fixing little axle non-dismountable, that needn't dismantle, wherein thick axle 9 is vertically installed in the two ends at angle on the little side, thin axle 8 is contained in the upper corner of big side last slice, a sulculus 5 is opened in the outer rim stage casing of the thick axle 9 of little side dress, can make little side when level attitude, bending tablet is 90 ° on the big side, with following sheet doubling (seeing Figure 11).The sheet connecting place has several projectioies under base plate and the big side, can with following sheet convex-concave engagement, lower shaft 2b is positioned at the center of bossing, the centre at edge, the narrow limit of base plate has one and the support card (seeing Figure 12, Figure 13) of little side uniform thickness.The shape of support card 7 can be square or triangle (seeing Figure 13, Figure 17), and when sheet meshed with right-angle plane up and down, support card was square; When sheet meshed with the plane, oblique angle up and down, support card was triangle (seeing Figure 17).When sheet meshed with the plane, oblique angle up and down, lateral plan shown in Figure 5 was substituted by Figure 15, and lateral plan shown in Figure 7 is substituted by Figure 16.Under holding state, support card is used for fixing little side on the one hand, plays the effect of clamp on the other hand, reduces base plate stressed in handling process.The height of support card just is the thickness of the sheet up and down sum after the doubling of big side.Little side bottom centre has correspondingly been drawn a supported hole 6, and under the holding state, proper and support card 7 is coincide.Capping is movable, and the capping area is slightly larger than open area on the case, can block the upper limb of big side and little side all around.

The utility model is a raw material with plastics, and in manufacturing process, circle or cylindrical void all can have been drawn in the sheet up and down and the little side of big side, can save a lot of raw materials, and a cylindrical void can be laterally drawn on top, little side, is convenient to carrying.The ratiometric that casing is long and high causes and is that 2:1, width can be slightly larger than height.Consider that the one man operation is convenient, casing length is advisable with 50～80 centimetres, should be 25～40 centimetres highly mutually, and width can be 30～45 centimetres.

Raw MAT'L of the present utility model does not contain the vegetation composition, does not have fibre shedding in the circular flow, also can be not mouldy because of making moist, so can not pollute to environment.Owing to be repeated use, so cost is not higher than carton; After each packing task is finished, deposit with folding mode, volume be strut 1/4, resistance to pressure, impact resistance all are higher than carton.

Fig. 1 is summary figure of the present utility model.
