Abstract

The utility model discloses a packing box which comprises a box cover and a box body, wherein the box body is formed by folding a base plate according to creases. Each side wall of the box body is provided with trapezoid support sheets which downwards extend from transversal crease lines at the lower port of the box body, and each support sheet is towards the inner part of the box body and is upwards bent. The two adjacent side edges of each support sheet are oppositely contacted and are mutually supported to form a convex support wall whose upper port is higher than the lower port of the box body, and the two adjacent support sheets of the support sheets are also provided with a stable structure which is formed by folding according to the creases and is used for keeping the convex support wall stable. The utility model has the advantages that the bottom of the box body is self-provided with the convex support wall whose upper port is higher than the lower port of the box body, and the convex support wall is used for supporting packed articles in the box body, and the packing box has good performance of shock resistance and pressure resistance. Compared with the existing packing box, the utility model reduces an additional base or a buffering cushion block made of expanded plastics, reduces packing cost, simplifies packing process to satisfy the requirement of mass production, and is beneficial for environment protection.

Description

Packing box

Technical field

The utility model relates to a kind of packing box, relates in particular to the support and the buffer structure that are arranged in the packing box between packed article bottom and the box body lower port.

Background technology

The box body of existing packing box to be adopted by the foldable formed mode of compacting substrate creasy (cardboard etc.), and box body is polygon, and wherein quadrangle is modal a kind of.The bottom of existing packing box box body does not have support and the buffer structure that forms one with box body, for making packaged box have certain antidetonation, compressive property, common way is to add base or rubber-like cushion pad to the box body bottom, this can increase the packing cost of product undoubtedly, and makes packaging operation seem loaded down with trivial details.In addition, cushion pad adopts foamed plastic to make more, can't recycling after the use, cause " white pollution ".

The utility model content

Technical problem to be solved in the utility model provides the packing box that a kind of box body bottom carries support and buffer structure, need not put into other base or cushion rubber again in the use.

The technical scheme that its technical matters that solves the utility model adopts is: packing box of the present utility model, include lid, box body, box body is pressed the folding line folding forming by substrate, it is characterized in that: each sidewall of described box body has the supporting blade that is extended down by box body lower port lateral fold alignment, each supporting blade bends in box body and upwards, two adjacent sides contact in opposite directions and support mutually in each supporting blade, constitute the protruding wall of support that its upper port is higher than the box body lower port; Also have on the two adjacent supporting blades in described each supporting blade by folding line is foldable formed and be used to keep supporting the stable rock-steady structure of protruding wall.

In technique scheme, described rock-steady structure is formed by two fins that are positioned at each supporting blade crease line both sides, have vertical folding line between the adjacent fins, in box body and when upwards bending, each flaps down bends and forms below adjacent supports sheet contact part and supports at each supporting blade.

The beneficial effects of the utility model are, the box body bottom carries the protruding wall of support that its upper port exceeds the box body lower port, and this supports protruding wall and is used to support packed article in the box body, has good antidetonation, compressive property; Compare with existing packing box, reduced additional base or the cushion pad made from foamed plastic, can reduce packing cost, simplify packaging process, help environmental protection again to satisfy the needs of Quantity production.Can be widely used as the external packing box of class article such as gift, bottle.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As showing, packing box of the present utility model includes lid 10, box body 20 as Fig. 1, and box body 20 is pressed the folding line folding forming by substrate.As shown in Figure 4, each sidewall of box body 20 has the supporting blade that is extended by box body 20 lower port crease line 0--0 downwards, as Fig. 1, shown in Figure 3, each supporting blade bends in box body 20 and upwards, two adjacent sides contact in opposite directions and support mutually in each supporting blade, constitute the protruding wall 30 of support that its upper port is higher than box body 20 lower port.Also have on the two adjacent supporting blades in each supporting blade by folding line is foldable formed and be used to keep to support the stable rock-steady structure of protruding wall 30.

Described rock-steady structure can adopt various ways, and it is a kind of shown in Fig. 2, Fig. 3.Shown in this two figure, described rock-steady structure is formed by two fins that are positioned at each supporting blade crease line both sides, have vertical folding line between the adjacent fins, in box body 20 and when upwards bending, each flaps down bends and forms below adjacent supports sheet contact part and supports at each supporting blade.For make in the supporting blade two adjacent sides in opposite directions contact wire have extreme length, support protruding wall 30 stability and support strength to improve to greatest extent, the shape of each supporting blade can preferably adopt trapezoidal.

For ease of and supporting protruding wall 30 folding forming easily with box body 20 in the packing box production process, as shown in Figure 1 and Figure 2, can offer the hole at two adjacent supporting blade roots.In in packing box of the present utility model, the cross-sectional plane of box body 20, the protruding wall 30 of support is polygon, and the most frequently used is quadrangle.Lid 10 can be independent parts, also can press the folding line folding forming on same substrate with box body 20.
