Example 1:

a packing box structure comprises a top panel and an inner lining part; virtual tangent lines are arranged on the top panel, a plurality of closed pressing areas are defined by the virtual tangent lines, and the virtual tangent lines are communicated with the pressing areas; when the outer side of the top panel is pressed by external force, the lining piece is abutted against at least one part of the top panel, so that the imaginary tangent line of the abutted part is not broken.

Specifically, regarding the top panel of box body, as shown in fig. 1 of the accompanying drawings, box body 1 includes on a top panel 10, the top panel is provided with virtual tangent line 130 line, and the physical structure intensity of the top panel of virtual tangent line department is relatively weak, and under the effect of external force, the position of virtual tangent line produces the crackle along the direction of virtual tangent line, therefore can follow virtual tangent line position and tear the top panel. The formed first pressing area 110 and the second pressing area 120 are used for pressing, and a user presses the first pressing area 110 and the second pressing area 120 to split virtual tangents around the first pressing area 110 and the second pressing area 120, so that a notch which can enable a finger to extend into and buckle the top panel is obtained, and the top panel is torn through the notch. Therefore, the top panel is more traditional in the packaging box with a top cover or a flip cover, the packaging effect can be realized only by the consumable material of one panel, and the consumable material is reduced. The virtual tangent line 130 is arranged only by cutting the surface of the top panel with a cutting die, and automatic batch production can be realized. The number of the pressing areas may be set to one or more. As shown in fig. 5 of the accompanying drawings, a specific box body is in an unfolded state, fig. 6 of the accompanying drawings is in an unopened state after assembly, a top panel 10 is arranged on one surface of a cuboid packaging box, the packaging box only needs to process a virtual tangent line on the top panel when the paperboard is cut or after the paperboard is cut, other parts and consumables do not need to be introduced, and material consumption is reduced; meanwhile, the processing link is simple, so that high automation can be realized, and the production efficiency is enhanced.

On the basis of the top panel, the overall shape of the inner lining member 2 may be circular as shown in fig. 7, and the inner lining member itself may be a product, such as a tea box, soap, etc., or an outer packing material for protecting the product itself, such as plastic foam, corrugated paper, rubber, etc. When the top panel 10 is pressed from the outside during transportation or transportation in a box shape, as shown in fig. 6, the abutting portion 20 of the lining member abuts against the inside of the top panel, and the lining member provides a certain supporting force to the top panel, thereby preventing the virtual cut line from being torn accidentally. When normally opened, the first pressing region 110 and the second pressing region 120 are opened by pressing, and the entire article including the lining member can be taken out as shown in fig. 8.

Example 2:

on the basis of the case body in embodiment 1, a cavity structure 3 is arranged between the pressing area and the lining member corresponding to the pressing area, so as to provide a space for forming an inverted structure for the pressing area. As shown in fig. 9, the lining member may be a polygonal structure or other structures, so as to form a cavity structure 3 below the first pressing region 110 and the second pressing region 120, so that after the first pressing region 110 and the second pressing region 120 are pressed down, a certain space can be provided, so that the virtual tangent line is turned inwards, and due to tearing, the virtual tangent line is thoroughly torn, thereby achieving the opening effect. In the overall structure, since the package is held in the hand as a whole, the package can be held more easily by pressing the package with fingers or a tool in the inner direction of the package so as not to come off, as shown in fig. 9 after opening. Meanwhile, due to the action of one surface of the abutting part 20, when the non-pressing area presses the top panel, the virtual tangent line cannot generate inner rolling, and further cannot be torn, so that the integral strength and the practicability of the combination of the packaging box are protected. Because materials such as cardboard, corrugated paper, cardboard, soft plastics have certain pliability, therefore even if like arc, circular or take the angle geometry as butt joint portion and top panel butt, the top panel can be because deformation and butt joint portion and the peripheral regional butt joint of butt joint portion production to reach the support effect.

Example 3:

in a preferred embodiment, the cavity structure is filled with a flexible cushioning material 4. As shown in fig. 11, the cavity structure 3 is filled with a flexible buffer material 4, which may be sponge, foam, rubber, fiber, plant fiber or other material with elasticity or flexibility. The flexible buffer material is filled in the cavity structure by utilizing the elasticity of the flexible buffer material, so that a certain supporting force is provided for the outer wall of the cavity structure, and the lining piece and other internal components can be protected at the same time. By virtue of its elasticity or flexibility, it is likewise possible to provide a space for inversion when the pressing region is pressed. After opening, as shown in fig. 12 of the drawings.

Example 4:

as shown in fig. 13, the lining member is an independent supporting member, and the lining member is used for wrapping the product to be packaged, and may be made of cardboard, corrugated paper, paperboard, soft plastic or other materials, so as to form a cavity structure for the pressing area to press.

In a preferred embodiment, the imaginary cut lines comprise spaced cuts through the top panel. As shown in fig. 1-3, the virtual lines of weakness are formed by the slits 130 through the top panel at intervals, the slits through the top surface can be directly cut by a cutting die, and compared with the pressing virtual lines generated by pressing a common paperboard, the virtual lines of slits through the top panel have better yield control rate and are easier to tear.

In a preferred embodiment, the incision is a bent shape, and the bent shape is formed by connecting a straight line segment and a curved line segment. As shown in the attached figures 1-3, because the panel has a certain thickness, the shape of the notch consists of a straight line section and a curved line section, so that in the wall thickness direction of the notch, the positions of the curved line section and the straight line section can provide supporting force at different angles when an external force acts, the notch is more stable and is not easy to crack under the action of a slight external force, and the stability of the notch structure is enhanced. The ratio of the width of the curved line segment in the direction of the straight line segment to the length of the straight line segment is 1: 2. As shown in the attached figure 2, the whole width of the cut is 2.1mm, the width of the straight line section is 1.4mm, and the width of the curve section in the direction of the straight line section is 0.7mm, so that the design can ensure that the good product rate can be better when the cutting die is used for cutting. The spacing between the cuts may be adjusted to increase or decrease the structural strength of the virtual tangent.

In a preferred embodiment, the cuts where the imaginary tangents intersect are in a "Y" configuration. As shown in fig. 1-2, the cutting die at the virtual tangent line junction is designed into a Y-shaped edge, so that the top panel can be cut with good aesthetic feeling.

In a preferred embodiment, the pressing area is in the shape of a letter comprising a first pressing portion and a second pressing portion. As shown in fig. 3 and 4, the first pressing region 110 is disposed in a convex shape, and thus includes a first pressing portion 111 and a second pressing portion 112, so that a user can press the first pressing portion preferentially to make the periphery of the first pressing portion of the first pressing region split tangentially. The overall cutting directions of virtual tangents on the peripheries of the first pressing part in the first pressing area and the second pressing part in the first pressing area are different, so when the virtual tangent on the periphery of the first pressing part in the first pressing area cracks, the paperboard is pressed due to the notch, a bend 113 is generated on a connecting line at the intersection of the virtual tangent of the first pressing part in the first pressing area and the virtual tangent of the second pressing part in the first pressing area, and the paperboard is sunken into the box body so as to form the notch; and the second pressing part of the first pressing area is not easy to tear compared with the first pressing part of the first pressing area, so that the formation of the concave notch of the first pressing part of the first pressing area is more efficient.

In a preferred embodiment, the upper surface of the top panel is rectangular, the pressing regions are arranged to include a first pressing region and a second pressing region, an imaginary tangent line constituting the first pressing region extends to two corners of the rectangle, and an imaginary tangent line constituting the second pressing region extends to the other two corners of the rectangle. As shown in fig. 1 or fig. 3, when the entire top panel is torn along the imaginary tangent line and is broken in the direction of the outer side of the box body, an opening in the shape of the outer circumference of the top panel is easily formed, which facilitates the removal of the articles in the package box. The rectangular packaging box is high in production efficiency and packaging efficiency, and large-scale automatic production is facilitated.

In a preferred embodiment, the imaginary tangent is axisymmetric. As shown in fig. 1 of the accompanying drawings, the axisymmetric virtual tangent line can facilitate the installation of the cutting die, so that the front and back sides of the top panel and the front and back directions of the panel do not need to be distinguished when the top panel is cut, and the structure is more flexible in production.

In a preferred embodiment, a sealing film is arranged on the inner side of the top panel, and the sealing film covers the position of the imaginary tangent line. The sealing film can increase the sealing performance of the equipment, and can provide waterproof and airtight effects for the objects in the packaging box when the cut penetrates through or the structure is damaged.
