Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the description of the drawings and the specific embodiments:

[0017] see figure 1 , figure 2 , a rotary open double-layer packaging box of the present invention includes an upper box body 4 and a lower box body 2, one end of the upper box body 4 and the lower box body 2 is provided with a flip cover 1, and the other end is the bottom of the box, which is connected to the flip cover 1 One side of the upper case body 4 and the back side of the lower case body 2 are hinged into one body through a hinge shaft.

[0018] The hinge shaft can be a rivet, and the rivet riveted the backs of the upper box body 4 and the lower box body 2 into one body. The hinge axis can be set at the axisymmetric center of the back of the upper box body 4 and the lower box body 2, or can be set on the bisector of the back of the flip 1, that is, perpendicular to the center line of the back of the box mouth. A...

Abstract

A rotary open type double layer packing box comprises an upper box body (4) and a lower box body (2), one end of the upper box body (4) and the same end of the lower box body (2) are provided with a flip (1), the other end is box bottom, and the surface connected with the flip (1) is the back. The packing box is characterized in that the back of the upper box body (4) and the back of the lower box body (2) are hinged into a whole by a hinge. When the two box bodies are overlapped, anyone of the two flips (1) can not be opened, self-locking is realized, so as to avoid that articles in the packing box is voluntarily dropped out. The invention is unique in opening mode, is rich in change, meets the psychological needs of different consumers and can improve safety and competitiveness of packing products.

Description

technical field [0001] The present invention relates to a packing box, more particularly to a double-layer packing box of a rotary open type. Background technique [0002] With the prosperity of the commodity economy and the continuous improvement of living standards, packaging has gradually evolved from an accessory to an important part of the commodity. At present, our common packaging boxes, such as cigarette boxes, are mostly rectangular packaging boxes with only one inner cavity, which can only contain one variety of items. For this reason, there are some double-layer packaging boxes on the market, and the double-layer packaging boxes are mostly drawer type. The drawer bucket of the drawer-type double-layer packaging box and the track structure of the outer box body are relatively complex, the processing is cumbersome, the outer layer mounting is troublesome, and the manufacturing cost is high. On the other hand, when the drawer-type double-layer packaging box is shak...
