Detailed Description

In order to specifically describe the embodiments and achieve the effects of the present application, an embodiment is provided and described below with reference to the drawings.

Referring to FIGS. 1 and 2, the end points A-E, a-e define the layout positions of the line segments 16,20,211,212,221,222, 252. Wherein "cut line" is defined as a line segment (shown as a solid line) extending through opposite sides of the sheet material, such as line segments 16,20,211,212,221, 222; "secant" is defined as a line segment (indicated by a solid thick line in the figure) that forms a knife edge on one side of the sheet material but does not penetrate through the knife edge to the other side of the sheet material, such as line segment 26; "fold line" is defined as a line (shown in phantom) that is cut into one side of the sheet material, such as line segments 251,253 to facilitate folding of the sheet material in half, or such as line segment 252 to reduce the thickness of the sheet material, although the fold line could be a cut having a shallower cut depth.

Referring to fig. 1 to 5, an embodiment of the sheet material after the cutting lines are arranged and folded in half is shown, the foldable sheet material 10 has a folding section to divide two folding portions 11,12, the folding section has two connecting portions 151,152 (the portions where the folding portions 11,12 are connected) located at opposite sides of the sheet material 10, and a cutting portion (the portion where the folding portions 11,12 are not connected) located between the connecting portions 151, 152. Wherein, a cutting line 16 is disposed at the center of the cutting portion (from the end point E to the end point E) to define the folding direction X (as shown in fig. 3), and the cutting lines and the folding lines on two adjacent sides of the cutting line 16 are symmetrically disposed.

The opposite ends E, E of the cutting line 16 are each provided with an opening 17. Each opening 17 has a top edge 20 adjacent to the connecting portions 151,152 and two side edges 211,212 remote from the connecting portions 151, 152. In addition, two extending cutting lines 221 (end points a, B or a, B are connected) and 222 (end points C, D or C, D are connected) are respectively arranged at two end points B, C or B, C of the top edge 20, and the extending cutting lines 221,222 and the top edge 20 form a curve with an opening facing the cutting line 16. In other words, the end points A, D or a, d are closer to the end points E or E than the top edge 20.

Thus, the width of the top edge 20 is substantially equal to the thickness T (see fig. 5) of the folded-over portions 11,12, so that the folded-over portions 11,12 are folded inward to be in contact with each other, and the cut surfaces cut by the cutting lines 16 are exposed; in addition, as shown in fig. 3, the opening 17 can make the plate material 10 around the contour generate larger deformation when being folded in half, and reduce the space obstruction generated by thickness extrusion. In this embodiment, the outline of the opening 17 is a little isosceles triangle with an arc angle at its vertex.

As shown in fig. 5, the extension cutting lines 221,222 extend outward from the contour of the opening 17, and the side edge 211 and the extension cutting line 221 are formed on the surface of the folded portion 11 to form an upward convex angle due to the pressing of the inner side surface, so that the space obstruction near the opening 17 and on the two sides of the cutting line 16 when the sheet material 10 is folded in two can be reduced. Thus, the cutting lines of the present embodiment may be disposed on the board 10 having a thickness of 1 cm or more, or on the multi-layer corrugated cardboard having more than three layers.

In the present embodiment, the middle section of the cutting line 16 is bent to form the outline of a tongue piece 40, and when the sheet material 10 is folded into two, the tongue piece 40 protrudes from the cutting surface of the cutting line 16, so that the sheet material 10 can be inserted and positioned on the base of the packaging material 50 (as shown in fig. 7) through the tongue piece 40. Meanwhile, the folded portion 11 may be provided with another tongue piece 40, at least one side surface of the plate material 10 is provided with a fixing groove 41, and the tongue piece 40 may be engaged with the fixing groove 41 to fix the folded shape of the plate material 10.

In the present embodiment, a positioning edge 24 is disposed on a side of the folding portion 11, as shown in fig. 4, a positioning side with a certain thickness is formed after the plate 10 is folded in half for positioning the product.

In this embodiment, the sheet material 10 is provided with two folding lines 251 perpendicular to the folding direction X and respectively connected to the end points of the top edge 20, so that the connecting portion 151 is easily recessed; further, the two folding lines 252 are provided at the outermost end points of the extension cutting lines 221 so as to be perpendicular to the folding direction X, so that the thickness of the sheet material 10 on both sides of the cutting line 16 can be reduced, and the sheet material 10 can be folded in half with less effort. In addition, a fold line 253 may be provided at the connection end of the tongue 40 to facilitate bending of the tongue 40.

In the present embodiment, the folded portion 12 is provided with a cut line 26 parallel to the cut line 16, the other side of the cut line 26 connects the folded portion 13, and the folded portion 13 is folded in the folding direction Y toward the outer side surface of the folded portion 12. Thus, the three folded portions 11,12,13 are connected to each other to form an N-shaped cross section, increasing the total thickness of the folded sheet material.

The cutting line layout can use a cutting die to form cutting lines, cutting lines and folding lines from the same side surface of the plate 10, and a multi-layer folding structure is generated, so that the folding plate is beneficial to simplifying the manufacturing process.

Referring to fig. 3, in the embodiment, the board 10 is formed by laminating two corrugated cardboard layers 261,262, each of the two corrugated cardboard layers 261,262 has two upper and lower surface papers and at least one wave layer, and the wave layers of the two corrugated cardboard layers 261,262 extend in a vertical direction and have different strengths.

Taking the cut lines 16 and the two-side folded portions 11 and 12 as an example, the plate body layer 262 with weak strength has a plurality of wave layers with large thickness and sparseness, and the cut lines of the folded plate material are formed to face the knife edge. A stronger plate layer 261 is located on the outside and may reinforce the connecting portions 151,152 to provide a stiff surface.

Taking the two-sided folded portions 12 and 13 of the cut line 26 as an example, the weak plate body layer 262 faces the knife edge to form the cut line 26, but the cut line 26 does not cut through the plate body layer 261, so the plate body layer 261 forms a connecting portion of the folded portions 12 and 13, the folded portions 12 and 13 can be folded in half from the folding direction Y toward the outside, and the exposed plate body layer 262 forms a side surface with a predetermined thickness. At this time, the plate body layer 261 may also provide sufficient connection strength.

Referring to fig. 6, a cutting line layout of another embodiment is illustrated, which differs from the above embodiment in that the sheet 10 is provided with two folded sections arranged in a straight line, wherein a connecting portion 152 is located at the center of the sheet 10; meanwhile, the number of the cutting lines 26 is two and is located at both sides of the cutting line 16, forming four folded portions connected to each other to form an M-shaped section. The cutting lines 16, the side edges 211,212, and the extended cutting lines 221,222 are continuously arranged in the folding direction X of the folded portions 11,12, and the cutting lines 16 are spaced apart from each other by the connecting portions 151,152, and the plurality of connecting portions provide support strength for the folded cross section.

In this embodiment, the thick paperboard is used as the plate material, in other embodiments, the plate material may also be a material bent by cutting lines, for example: foaming panel, plastic sheet, resin panel through increase thickness of fifty percent discount panel, satisfy the demand of product location or buffering.

Specifically, as shown in fig. 7, the whole packing material 10 may be configured with a groined structure embedded and combined with each other to define a containing space for the commodity, and a tongue piece may be disposed below the groined structure to be inserted into the base for positioning, so as to improve the mechanical strength of the internal structure.
