the invention discloses a chitose nanometer fiber film and preparing method with stable shape structure in the carrier domain, which comprises the following steps: forming transparent solution in the water mixed solvent through dissolving chitose and polyvinyl alcohol in the glacial acetic acid; putting the spin liquid in the feeder; connecting spin-spraying head with high-pressure power at 5-30 kV; spinning; immersing the film material in the strong alkaline solution; possessing stable shape structure.

The invention discloses a cover-containing packaging box convenient to disassemble and combine. The packaging box is characterized in that the two ends of a short side plate are connected with inner wing plates which are respectively attached to the two ends on the inner side of a long side plate after folding; the width of the inner wing plates after folding is the same as the height of the long side plate; outer wing plates which are attached to the outer side of the long side plate after folding are connected on the two sides of a cover plate; the height of the inner wing plates and the outer wing plates is the same as the height of the short side plate; at least two outer penetrating holes which penetrate through outer wing plate bodies are formed in the outer wing plates; middle penetrating holes are formed in the positions, opposite to the outer penetrating holes, of the long side plate; inner penetrating holes are formed in the positions, corresponding to the middle penetrating holes, of the inner wing plates; at least two bayonets which are distributed at equal intervals in the circumferential direction are formed in the side walls of locating pipes; first oblique angles are chamfered on the edges on the same sides, in the circumferential direction of the inner sides of the locating pipes, of the bayonets; male connectors are provided with clamping hooks which are connected on elastic arms, are in one-to-one correspondence with the bayonets, and are clamped in the bayonets; and second oblique angles are chamfered on the outer edges, corresponding to one sides of the first oblique angles of the bayonets, of the clamping hooks. According to the cover-containing packaging box convenient to disassemble and combine, the shape is stable, the packaging box can be quickly assembled and disassembled, and the cost is low.

The invention discloses a packaging box disassembled and assembled through two steps and provided with a cover. The packaging box is characterized in that an outer wing through hole running through a body thereof is at least formed in an outer wing plate; an outer ring annular recess is arranged on an outer edge, outside a box, of the outer wing through hole; a long side plate through hole, opposite to the outer wing through hole, is formed in a long side plate; a long side plate annular recess is arranged on an inner edge, inside the box, of the long side plate through hole; an inner wing through hole running through the body thereof is at least formed in an inner wing plate; an inner wing annular recess is arranged on an inner edge, inside the box, of the inner wing through hole; a short side plate through hole, opposite to the inner wing through hole, is formed in a short side plate; and a short side plate annular recess is arranged on an outer edge, outside the box, of the short side plate through hole. The packaging box disclosed by the invention is stable in shape, does to have a protrusion, can be quickly disassembled and assembled, and is low in cost.

The invention discloses a lidded packaging box conveniently disassembled at two steps. The lidded packaging box is characterized in that at least one outer wing through hole penetrating through the main body of each outer wing plate is arranged in each outer wing plate, long side plate through holes which are opposite to the outer wing through holes are arranged in long side plates, at least one inner wing through hole penetrating through the main body of each inner wing plate is arranged in each inner wing plate, and short side plate through holes which are opposite to the inner wing through holes are arranged in short side plates; and a connecting buckle is provided with female connectors and male connectors, the male connectors are provided with clamping hooks which are connected to an elastic arm, are in one-to-one correspondence with clamping openings and are clamped into the clamping openings, second bevel angles are chamfered on the outer edges of the sides corresponding to the first bevel angles of the clamping openings of the clamping hooks, the clamping hooks can move along the first bevel angles by utilizing the second bevel angles and are accordingly separated from the clamping openings, the outer end of the elastic arm is connected with male connector outer edges which are pressed on the outer edges of the through holes at the outer side, and the inner sides of the male connector outer edges are connected with prismatic holes. The lidded packaging box is stable in form, can be rapidly disassembled and is low in cost.
