Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a paper box with an automatically unfolded inner partition board. Background Art

[0002] Paper boxes are common packaging containers, usually made of paper or cardboard. They have a wide range of uses in various occasions, such as for packaging food, gifts, documents, etc. Paper boxes can be simple square structures or complex folded or combined shapes. They are usually light, environmentally friendly, and can be personalized through printing or other decoration methods to make them more attractive. The use of paper boxes can reduce the use of non-degradable materials such as plastics and contribute to environmental protection.

[0003] However, existing paper boxes generally do not have inner partition boards. Plane patterns can be drawn or three-dimensional patterns can be pasted on the inner partition boards. Once the inner partition boards are unfolded, the patterns can be displayed, enabling the paper boxes to have more display and publicity functions. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a paper box with an automatically unfolded inner partition board.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A paper box with an automatically unfolded inner partition board, comprising: a paper box, a box cover is provided at the top of the paper box, a circular groove is opened in the middle of the top of the box cover, an inner partition board is horizontally bonded to the bottom of the circular groove, and a semi-circular cardboard is rotationally bonded to the middle of the top of the inner partition board;

[0007] A limiting structure for limiting the position of the semi-circular cardboard on the top of the inner partition board;

[0008] Two folding spring paper strips, and one ends of the two folding spring paper strips are respectively welded to both sides of the top of the semi-circular cardboard;

[0009] A flexible strip light is fixedly installed at the edge of the inner top of the box cover;

[0010] A power supply structure for supplying power to the flexible strip light.

[0011] When the pattern on the inner partition does not need to be displayed, the semi-circular cardboard is fixed on one side of the inner partition by the limiting structure to cover the pattern. When the pattern needs to be displayed, the limiting structure is loosened, and the semi-circular cardboard automatically flips to the other side of the top of the inner partition under the rebounding force of the two folding spring strips. The limiting structure is used again to fix the semi-circular cardboard on the other side of the inner partition to prevent the semi-circular cardboard from rebounding. The unfolding of the semi-circular cardboard does not require manual operation and can automatically display the pattern on the top of the inner partition, enabling the paper box to have more display and publicity functions;

[0012] And when the semi-circular cardboard unfolds, the power supply structure is automatically used to energize the flexible strip light, and the flexible strip light lights up to provide light for the pattern on the top of the inner partition, making the display effect better.

[0013] As a further technical solution of the present invention, the limiting structure includes a connecting strip and a clamping strip. The connecting strip is horizontally bonded to the middle of one side of the semi-circular cardboard. Insertion strips are vertically bonded to the opposite sides of the top of the box cover. There are two clamping strips, which are respectively horizontally bonded to the tops of the two insertion strips. A card slot is opened at the front end of the connecting strip, and the insertion strip and the clamping strip are adapted to the card slot.

[0014] Align the card slot of the connecting strip with the top of the insertion strip and insert it. The card slot squeezes the two ends of the clamping strip towards both sides of the insertion strip to close, so that the insertion strip and the closed clamping strip are inserted into the card slot. When the closed clamping strip passes through the card slot, the closed clamping strip expands at a certain angle under its own elasticity and is stuck on the top of the card slot to prevent the insertion strip from disengaging from the card slot, thereby limiting and fixing the position of the semi-circular cardboard; when the position of the semi-circular cardboard needs to be changed, just lift the connecting strip upwards, then the top of the card slot generates resistance to the clamping strip, and the resistance causes the clamping strip to deform upwards and close, so that the clamping strip can disengage from the card slot. The fixing and loosening of the connecting strip are both convenient and fast, facilitating the change of the position of the semi-circular cardboard.

[0015] As a further technical solution of the present invention, through slots are opened at both ends of one side of the inner partition. C-shaped cardboard is bonded to the bottom of the inner partition below the two through slots. The other ends of the two folding spring strips respectively pass through the two through slots, and the other ends of the two folding spring strips are bonded to the top of the C-shaped cardboard.

[0016] When the semi-circular cardboard rotates to the other side of the top of the inner partition, the semi-circular cardboard squeezes the two folding spring strips into the two through slots respectively, and the C-shaped cardboard fixes the other ends of the two folding spring strips.

[0017] As a further technical solution of the present utility model, the power supply structure includes a first button battery and a second button battery. A battery slot is provided in the middle of one side of the inner partition board. The first button battery is installed inside the battery slot, and the second button battery is installed in the middle of the top of the semi-circular cardboard. A circuit is installed in the battery slot and is electrically connected to the flexible strip light. The first button battery and the second button battery are electrically connected to the battery slot.

[0018] When the semi-circular cardboard rotates to the other side of the top of the inner partition board, at this time, the second button battery is snapped into the battery slot above the first button battery. Both the first button battery and the second button battery are installed in the battery slot to complete power-on, so as to supply power to the flexible strip light.

[0019] The beneficial effects of the present utility model are as follows: The semi-circular cardboard automatically flips to the other side of the top of the inner partition board under the action of the rebound force of the two folding spring paper strips. The unfolding of the semi-circular cardboard does not require manual operation and can automatically display the pattern on the top of the inner partition board, enabling the paper box to have more display and publicity functions; and when the semi-circular cardboard unfolds, the power supply structure automatically powers on the flexible strip light, and the flexible strip light lights up to provide light for the pattern on the top of the inner partition board, making the display effect better.
