Description

Technical Field

[0001] This utility model relates to a packaging body, and more particularly to a packaging body with a hidden machine-readable mark. Background Technology

[0002] The use of machine-readable labels such as QR codes on packaging for anti-counterfeiting authentication or to provide promotional information is becoming increasingly common. However, directly printing or attaching these machine-readable labels to the outside of the packaging can lead to unintended reading, resulting in counterfeiting or the promotional information failing to achieve its intended purpose. Furthermore, these machine-readable labels are easily damaged during the production, storage, transportation, and sales processes, rendering them unreadable. Therefore, documents such as CN221954918U have proposed using hidden QR codes to solve these technical problems.

[0003] However, due to their hidden nature, these hidden QR codes can only be seen when consumers uncover or fully open the sealed part. This causes inconvenience in use and makes it difficult for consumers to notice these hidden QR codes. Furthermore, the extra operation may cause consumers to reduce their efforts to read these codes, thus rendering the purpose of setting these machine-readable labels meaningless.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] Therefore, this utility model provides a packaging body to solve the above-mentioned technical problems.

[0006] A packaging body includes a base, the base including a top or a bottom, the top including a top surface, the bottom including a bottom surface, and the top or bottom including a horizontal sealing portion for sealing the packaging body. The horizontal sealing portion includes an attached state and an upright state, which are attached to the top surface. The top or bottom surface is also provided with a machine-readable mark. When the horizontal sealing portion is in the attached state, the machine-readable mark includes a partially obscured area formed by the horizontal sealing portion and an exposed area formed by the unobscured area. The obscured area is greater than or equal to 30% of the area of ​​the machine-readable mark, and the exposed area is greater than or equal to 10% of the area of ​​the machine-readable mark.

[0007] The machine-readable identifier is a QR code.

[0008] Among them, the obscured area is greater than or equal to 70% of the machine-readable label area, and the exposed area is greater than or equal to 15% of the machine-readable label area.

[0009] The top surface includes a first area and a second area. The horizontal sealing part is foldable along the horizontal sealing fold line, which separates the first area and the second area. The machine-readable mark is set in the first area. When the horizontal sealing part is folded towards the first area and attached to the first area, the horizontal sealing part is in an attached state. When the horizontal sealing part is folded towards the second area, the horizontal sealing part is in an upright state.

[0010] The substrate further includes a side portion, which includes a pair of first side surfaces and a pair of second side surfaces arranged opposite to each other, with the first side surfaces and second side surfaces being adjacent to each other. Meanwhile, the top surface is separated from the first side surface by a first edge line, and the top surface is separated from the second side surface by a second edge line. The horizontal sealing fold line is parallel to the first edge line, and the second edge line is perpendicular to the first edge line. At the same time, the horizontal sealing fold line is perpendicular to the second edge line.

[0011] The packaging body further includes a pair of corner portions located on both sides of the top. Each corner portion includes a first extension, a second extension, and a horizontal sealing extension that are stacked together. The first extension extends from the top to the side, the second extension extends from the second side to the top, and the horizontal sealing extension extends from the horizontal sealing portion to the corner portion. The corner portions are configured to fold along the second edge line towards the second side and attach to the second side.

[0012] The readable identifier is set separately from the horizontal seal line.

[0013] The readable markings are not located on the horizontal seal.

[0014] The top also includes a suction port, which covers a portion of the suction port when the horizontal seal is in an attached state.

[0015] The substrate is formed by folding a packaging sheet, which is a multi-layered material. The multi-layered material includes a paper structure layer, an outer structure layer located outside the paper structure layer, and an inner structure layer located inside the paper structure layer.

[0023] Please refer to Figures 1-3 The first embodiment of this utility model provides a packaging body, which includes a base 10. The base 10 is formed by folding a packaging sheet into a three-dimensional shape including a top 11 and a side 12, and has a receiving cavity for accommodating products.

[0024] Understandably, the substrate 10 also includes a bottom portion opposite to the top 11.

[0025] Specifically, the packaging sheet is a multi-layered material; more specifically, the multi-layered material includes a paper structure layer, an outer structure layer located outside the paper structure layer, and an inner structure layer located inside the paper structure layer.

[0026] The paper structure layer is used to provide stiffness for the packaging. The paper structure layer can be natural paper, synthetic paper, or a blend of paper. Natural paper refers to paper formed by wet forming using natural fibers. Synthetic paper refers to paper formed by wet forming, dry forming, hydroentangling, needle punching, or other forming methods using synthetic fibers. Blended paper refers to paper formed by wet forming, dry forming, hydroentangling, needle punching, or other forming methods using both natural and synthetic fibers. It is understood that natural fibers can be at least one of wood pulp fiber, bamboo fiber, straw pulp fiber, sugarcane pulp fiber, and cotton pulp fiber.

[0027] In addition, the paper structure layer can be a multi-layered structure, including 2, 3, or 4 fiber-containing layers, and may also include a coating layer. In one specific embodiment, the paper layer includes a coating layer, a surface layer, a core layer, and a bottom layer.

[0028] The paper layer has a density of 30-330 g / m². 2 The basis weight, preferably, is 150 g / m². 2 or greater than or equal to 177g / m 2 or greater than or equal to 220g / m 2 or greater than or equal to 300g / m 2 The bulk thickness of the paper layer is greater than or equal to 1.7 cm. 3 / g, or greater than or equal to 1.9 cm 3 / g, or greater than or equal to 2.05 cm 3 / g.

[0029] The outer structural layer is used to provide a barrier against water, oxygen, etc. for the packaging. Specifically, the outer structural layer includes a barrier layer mainly formed of polyethylene. In one specific embodiment, the outer structural layer includes a multi-layer structure, including an outer barrier layer, an inner barrier layer, and a barrier coating located between the outer barrier layer and the inner barrier layer.

[0030] The barrier coating can be a metal or a metal oxide, or a coating with barrier properties. The top layer is used to further block oxygen and water vapor, and the barrier coating is used to block light.

[0031] When the barrier coating is a metal or a metal oxide, the metal can be copper, aluminum, titanium, or chromium, and the oxide can be aluminum oxide, copper oxide, titanium oxide, or chromium oxide.

[0032] When the barrier coating is a coating material, the specific coating material can be PVA, EVOH, PPG, etc., and the coating thickness is in the range of 0.5-2 micrometers.

[0033] It is understood that the outer barrier layer and the inner barrier layer can be polyethylene, polypropylene and other olefin resins, including low-density polyethylene, linear low-density polyethylene, metallocene linear low-density polyethylene, high-density polyethylene, medium-density polyethylene, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / ethyl acrylate copolymer and other resins, and can also be used in appropriate combinations.

[0034] The inner structural layer is used to prevent the contents from penetrating into the packaging material, while providing an adhesive layer for horizontal and vertical sealing, protecting the product flavor and the integrity of the packaging material. The inner structural layer can be made of olefin resins such as polyethylene and polypropylene, including low-density polyethylene, linear low-density polyethylene, metallocene linear low-density polyethylene, high-density polyethylene, medium-density polyethylene, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / ethyl acrylate copolymer, and other resins, and can also be used in appropriate combinations.

[0035] In the above description, "polymer" refers to a polymeric compound prepared by polymerizing the same or different types of monomers. "Copolymer" refers to a polymer prepared by polymerizing at least two different types of monomers.

[0036] Typically, the folding refers to folding the packaging sheet along pre-made indentations. These indentations divide the packaging sheet into multiple base surfaces, which are then folded along the indentations to form cavities for containing liquid products. The indentations are grooves on the surface of the packaging sheet, creating weakened areas corresponding to the indentations. This allows the packaging sheet to be easily folded along the indentations without wrinkles or delamination occurring in the areas corresponding to or adjacent to the indentations during the folding process. Alternatively, the indentation can be achieved by passing the packaging sheet through a pair of pressure rollers. These rollers include an upper roller with protrusions corresponding to the indentation shape and a bottom roller spaced apart from the upper roller. As the packaging sheet passes through this gap, pressure is applied to the corresponding areas by the protrusions, forming the pre-made indentation.

[0037] The top 11 includes a top surface 111 and a horizontal sealing portion 13 for sealing the packaging. It can be understood that the horizontal sealing portion 13 is a strip-shaped area formed by joining the packaging sheet in the transverse direction. The joining refers to the connection of the joined materials to form a whole. Usually, it can be formed by heat melting or bonding. The heat melting can be achieved by heating the material itself to reach its melting point temperature, then locally melting and solidifying to form a connection. Alternatively, external energy such as ultrasound can be applied to the material to cause local high-temperature melting and solidification to form a connection. The bonding can be achieved by using an adhesive to connect adjacent materials under the action of the adhesive.

[0038] The horizontal sealing part 13 includes an attached state and an upright state. It can be understood that when the horizontal sealing part 13 is in the attached state, the horizontal sealing part 13 blocks a part of the top surface 111. The blocking means that the blocked area is not visible. When the horizontal sealing part 13 is in the upright state, the blocked area should be visible.

[0039] The top surface 111 is also provided with a machine-readable mark 20. It can be understood that the machine-readable mark 20 can be a QR code, a barcode, or other machine-readable mark 20 set in a predetermined encoding form. At the same time, the QR code can be an encoding that meets the ISO / IEC 18004 standard or an encoding set in other custom encoding forms.

[0040] Furthermore, the machine-readable identifier 20 is a QR code.

[0041] When the horizontal sealing portion 13 is in the attached state, the machine-readable mark 20 includes a partially obscured area 22 formed by the sealing portion covering a part of the machine-readable mark 20 and an exposed area 21 formed by the unobscured portion. The obscured area 22 is greater than or equal to 30% of the area of ​​the machine-readable mark 20, thereby making the machine-readable mark 20 unreadable. In addition, the exposed area 21 is greater than or equal to 10% of the area of ​​the machine-readable mark 20, so that the user can see the machine-readable mark 20 and then actively use the machine-readable mark 20.

[0042] Furthermore, the obscured area 22 is greater than or equal to 70% of the area of ​​the machine-readable mark 20, and the exposed area 21 is greater than or equal to 15% of the area of ​​the machine-readable mark 20.

[0043] Furthermore, the top surface 111 includes a first area and a second area. The horizontal sealing part 13 is foldable along the horizontal sealing fold line 130, which separates the first area and the second area. The machine-readable mark 20 is disposed in the first area. When the horizontal sealing part 13 is folded toward the first area and attached to the first area, the horizontal sealing part 13 blocks the machine-readable mark 20. When the horizontal sealing part 13 is folded toward the second area, the horizontal sealing part 13 no longer blocks the machine-readable mark 20 and the machine-readable mark 20 is exposed.

[0044] Furthermore, the side portion 12 includes a pair of first side surfaces 121 and a pair of second side surfaces 122 arranged opposite to each other, with the first side surfaces 121 and the second side surfaces 122 arranged adjacent to each other. Meanwhile, the top surface 111 is separated from the first side surface 121 by a first edge line 110, and the top surface 111 is separated from the second side surface 122 by a second edge line 120. In a specific embodiment, indentations are provided at positions corresponding to the first edge line 110 and the second edge line 120 to fold along the first edge line 110 and the second edge line 120 to form the first side surface 121, the second side surface 122, and the top surface 111.

[0045] Furthermore, the horizontal sealing fold line 130 is parallel to the first side line 110, the second side line 120 is perpendicular to the first side line 110, and the horizontal sealing fold line 130 is perpendicular to the second side line 120.

[0046] Furthermore, the packaging body also includes a pair of corner portions 14 located on both sides of the top 11. The corner portions 14 include a first extension 141, a second extension 142, and a horizontal sealing extension 131 stacked together. The first extension 141 and the second extension 142 are both triangular. The first extension 141 extends from the top surface 111 to the side, and the second extension 142 extends from the second side surface 122 to the top surface 111. The horizontal sealing extension 131 extends from the horizontal sealing portion 13 to the corner portions 14. The corner portions 14 are configured to fold along the second edge line 120 to the second side surface 122, causing the horizontal sealing portion 13 to bend, thereby keeping the packaging body in a predetermined shape and keeping the horizontal sealing portion 13 in an attached state.

[0047] Furthermore, the readable identifier 20 is set separately from the horizontal sealing line 130.

[0048] Furthermore, the readable mark 20 is not provided on the horizontal sealing part 13, that is, there is no part of the readable mark 20 on the horizontal sealing part 13. On the one hand, this can avoid damage to the readable mark 20 during the sealing process, and on the other hand, it can make the readable mark 20 fully exposed only when the horizontal sealing part 13 is upright or partially upright, without the need for the horizontal sealing part 13 to be completely folded or flattened.

[0049] Please refer to the following for further details. Figure 4 ,exist Figure 4 The image shows a top 31 configuration in another embodiment. In this embodiment, the top 31 further includes a suction port 30. When the horizontal seal 33 is in an attached state, the horizontal seal 33 covers a portion of the suction port 30, so that when the user draws liquid from the accommodating cavity through the straw, the horizontal seal 33 needs to be raised to an upright state. In this case, the suction port 30 can be exposed, and the machine-readable mark 40 can also be exposed.

[0050] It is understood that the bottom includes the bottom surface, the horizontal seal can be set at the bottom, and the machine-readable mark can be set at the bottom surface. In this case, the setting form of the horizontal seal and the machine-readable mark at the bottom is basically the same as that at the top, and will not be described in detail here.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
