Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and more specifically, to a packaging box. Background Art

[0002] Paper packaging, folded through a special cutting design, has become a mainstream packaging in the market, offering advantages such as environmental friendliness and convenience. However, conventional packaging boxes typically have a tamper-evident feature after being formed once. Disassembling the box during use destroys the outer packaging and makes it unusable. This can also cause inconvenience if the contents are not fully used, as the box cannot be reclosed, making it difficult to store the contents.

[0003] Therefore, there is an urgent need for a packaging box that can be reused, stored for secondary use, and has an anti-tampering function to enhance the consumer experience. Utility Model Content

[0004] The main purpose of the utility model is to provide a packaging box, aiming to solve the technical problem in the prior art that the packaging box cannot be reused and repackaged once it has been disassembled.

[0005] To achieve the above object, the present invention provides a packaging box, which is formed by folding a folding sheet, wherein the folding sheet has a first surface and a second surface, and the folding sheet includes a front panel, a rear panel, a left panel, a right panel, and a swing cover; the left panel and the right panel are respectively located on the left and right sides of the front panel, and the swing cover and the rear panel are respectively located on the upper and lower sides of the front panel;

[0006] A first fold line is provided between the front panel and the rear panel, a second fold line is provided between the left panel and the front panel, a third fold line is provided between the right panel and the front panel, and a fourth fold line is provided between the swing cover and the front panel;

[0007] The end of the rear panel away from the first fold line is provided with a tear line and a socket, and the socket is closer to the first fold line than the tear line; the swing cover is provided with an insert tongue corresponding to the socket;

[0008] When the packaging box is formed, a first adhesive is set on the first surface of the back panel, and the first surface of the back panel is bonded to the second surface of the swing cover through the first adhesive. The first adhesive is positioned along the lower edge of the back panel, and the first adhesive and the socket are respectively located on both sides of the tear line; a second adhesive is set on the second surfaces of the left panel and the right panel, and the first surface of the back panel is bonded to the second surfaces of the left panel and the right panel through the second adhesive.

[0009] Through the aforementioned structure, this utility model utilizes a single-piece folding sheet to fold into an envelope-like packaging box, resulting in an ingenious and convenient design. After integral molding, the easy-tear line on the back panel serves as a tamper-evident feature, preventing the contents from being replaced. Furthermore, after tearing the box open along the easy-tear line, the swing lid opens, and the tongue on the swing lid engages with the socket on the back panel to reseal the box, fulfilling its original packaging function and ensuring the safekeeping of remaining items. This one-piece packaging box design offers a sophisticated structure and simple packaging, significantly improving packaging efficiency.

[0010] Preferably, adhesive boundaries are provided on the left and right panels, and the second adhesive is located on the left and right panels along the adhesive boundaries toward the first fold line. The distance between the adhesive boundaries and the fourth fold line is no less than the height of the swing cover. The provision of adhesive boundaries prevents the swing cover from adhering to the left and right panels after being bent during the packaging molding process, thereby preventing inconvenience in use.

[0011] Preferably, the inserting tongue protrudes from the outer edge of the swing cover and is in an outwardly convex arc shape. The inserting tongue protrudes from the outer edge of the swing cover and is arranged in a convex arc shape, which makes it easier to insert the inserting tongue into the socket to form a secondary packaging of the packaging box.

[0012] Preferably, the ends of the left and right panels near the fourth fold line are arranged at an angle downward from the fourth fold line. The ends of the left and right panels near the fourth fold line are arranged at an angle to facilitate easier removal of the flap after the tear line is torn open.

[0013] Preferably, the left and right panels are angled upward from the first fold line at their ends near the first fold line. This angled position near the first fold line facilitates folding the box and makes bending the rear panel easier without being restricted by the right-angled edges formed after bending.

[0014] Preferably, the swing cover is in the shape of a raised arc with a high middle and low ends. The swing cover is lower at both ends, making it easier to take out the items from the envelope-shaped paper box, thereby making it convenient to open the packaging box and take out the items.

[0015] Preferably, the folding sheet is made of cardboard, which is more convenient, environmentally friendly and reusable. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1 As shown, it is a schematic diagram of a planar expansion of a packaging box in a specific embodiment provided by the utility model. The packaging box is folded from a folding sheet 1, and the folding sheet 1 has Figure 1 The first surface 11 is shown facing upward along the paper surface and the second surface 12 is shown facing downward along the paper surface (the second surface 12 is not shown in the figure). The direction description in this embodiment is relative to Figure 1 The folding plate 1 specifically includes a front panel 101, a rear panel 102, a left panel 103, a right panel 104, and a swing cover 105, each having a first surface 11 and a second surface 12. The left panel 103 and the right panel 104 are located on the left and right sides of the front panel 101, respectively, and the swing cover 105 and the rear panel 102 are located on the upper and lower sides of the front panel 101, respectively.

[0030] A first fold line 106 is defined between the front panel 101 and the back panel 102, a second fold line 107 is defined between the left panel 103 and the front panel 101, a third fold line 108 is defined between the right panel 104 and the front panel 101, and a fourth fold line 109 is defined between the flap 105 and the front panel 101. A tear line 110 and a slot 111 are defined on the end of the back panel 102 away from the first fold line 106. The slot 111 is closer to the first fold line 106 than the tear line 110 is to the first fold line 106. In other words, the tear line 110 is closer to the outer edge of the back panel 102. The flap 105 is provided with a tongue 112 that corresponds to the slot 111.

[0031] When the packaging box is formed, one embodiment (not shown in the figure) is as follows: first, the swing cover 105 is bent along the fourth fold line 109 toward the first surface 11; then, the left side panel 103 and the right side panel 104 are bent toward the first surface 11 along the second fold line 107 and the third fold line 108 respectively; a first adhesive 113 is provided on the first surface 11 of the back panel 102, and the first adhesive 113 is located along the lower edge of the back panel 102, and the first adhesive 113 and the socket 111 are respectively located on both sides of the easy tear line 110; and a second adhesive 114 is provided on the second surface 12 of the left side panel 103 and the right side panel 104. Figure 2 As shown, the back panel 102 is finally bent along the first fold line 106 toward the first surface 11, and is bonded to the swing cover 105 and the left side panel 103 and the right side panel 104 respectively by the first adhesive 113 and the second adhesive 114, thus completing the assembly of the packaging box. At this point, the second surface 12 of the folding sheet 1 forms the outer surface of the packaging box, and the first surface 11 forms the inner surface of the packaging box. When in use, the swing cover 105 can be removed from the inside by simply tearing the easy tear line 110 (as shown in FIG. 1 ). Figure 5 As shown), when secondary packaging is required, the swing cover 105 is bent again and the tongue 112 is inserted into the socket 111 to complete the secondary packaging (as shown). Figure 6 shown).

[0032] like Figures 2-4 As shown, another embodiment of the packaging box forming is to first bend the left side panel 103 and the right side panel 104 toward the first surface 11 along the second folding line 107 and the third folding line 108 respectively ( Figure 2 ); secondly, the flap 105 is bent along the fourth fold line 109 toward the first surface 11 ( Figure 3); a first adhesive 113 is provided on the first surface 11 of the rear panel 102. The first adhesive 113 is located along the lower edge of the rear panel 102. The first adhesive 113 and the socket 111 are respectively located on both sides of the easy-tear line 110. A second adhesive 114 is provided on the second surface 12 of the left panel 103 and the right panel 104. Finally, the rear panel 102 is bent toward the first surface 11 along the first fold line 106 and bonded to the swing cover 105 and the left panel 103 and the right panel 104 respectively by the first adhesive 113 and the second adhesive 114. The assembly of the packaging box is completed. Figure 4 In this embodiment, preferably, adhesive boundaries 115 are provided on the left and right panels 103, 104. The second adhesive 114 is located along the left and right panels 103, 104 along the adhesive boundaries 115 toward the first fold line 106. The parallel distance between the adhesive boundaries 115 and the fourth fold line 109 is no less than the height of the flap 105. This prevents the flap 105 from adhering to the left and right panels 103, 104 due to the second adhesive 114 when folded, thereby preventing it from adhering to the flap 105 after unpacking, requiring the adhesive on both sides of the flap 105 to be torn to open the flap 105 and access the contents.

[0033] like Figures 1 to 3 As shown, in some specific embodiments, the insert tongue 112 protrudes from the outer edge of the swing cover 105 and has an outwardly convex arc shape. Protruding the insert tongue 112 from the outer edge of the swing cover 105 can reduce the material used in the swing cover 105, which is more cost-effective and environmentally friendly. In some other embodiments, the insert tongue 112 can also be formed by cutting a cutout near the edge of the swing cover 105 (not shown). Preferably, the swing cover 105 is configured as a convex arc shape with a high center and low ends. A swing cover 105 with lower ends makes it easier to remove from an envelope-shaped paper box.

[0034] like Figure 1 As shown, in some specific embodiments, the ends of the left and right panels 103 and 104 near the fourth fold line 109 are angled downward from the fourth fold line 109. This angled arrangement facilitates folding and packaging, and also facilitates the removal of the flap 105. In particular, when the flap 105 is folded first and then the left and right panels 103 and 104 are folded, the flap 105 is more easily removed from the interior when the package is opened. Preferably, the ends of the left and right panels 103 and 104 near the first fold line 106 are angled upward from the first fold line 106. This angled arrangement facilitates the folding of the rear panel 102 when it is bent, without being restricted by the right-angled edges of the left and right panels 103 and 104.

[0035] In some specific embodiments, the folding sheet 1 is a cardboard. The cardboard is folded to form a packaging box, which is light to use, environmentally friendly and pollution-free, and can be reused after being discarded.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
