[0001] This invention relates to the field of packaging, and more particularly to a packaging box with a blister seal and a method for producing the same. Background Technology

[0002] Traditional packaging boxes, especially top-opening boxes or base boxes, have lids and bases that seal the openings at both ends of the box body. Blister cushioning is fixed to the lid or base to help position the product.

[0003] The box lids are all made of gray board and face paper. In other words, the entire box lid sealing structure includes gray board, face paper and blister cushioning. The box lid sealing structure requires the use of gray board, which is relatively expensive. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging box with a blister seal and its production method. The main principle is to use the blister cushioning component commonly used in packaging as the blister seal component to seal the top of the packaging box.

[0005] An anti-counterfeiting packaging box with a blister seal is provided. The packaging box includes a box body and a blister seal component. The box body is made of box body paper laminated with a box body base. The blister seal component is located on the top of the box body as the sealing body. The blister seal component includes a top plate and side plates extending downward from the edge of the top plate. The top plate is located at the sealing point of the box body, and the side plates are bonded to the inner wall of the box body.

[0006] Furthermore, the blister sealing component also includes a positioning part located in the middle of the top plate and extending into the box body.

[0007] Furthermore, the top plate is square, and there are four side plates. The four side plates are respectively connected to the four sides of the top plate and are interconnected with each other. Side plate extension plates extend from the lower part of the side plates, and the side plate extension plates are not connected to each other.

[0008] Furthermore, the side plate extension is provided with a cut, and the cut line formed by the cut is a bending cut line or an opening cut line.

[0009] Furthermore, the top plate of the blister sealing component is provided with a concave-convex structure.

[0010] Furthermore, the top and side panels of the blister sealing component are covered with adhesive paper.

[0011] Furthermore, the side extension plate of the blister sealing component is bonded to the inner wall of the box body.

[0012] Furthermore, after the blister sealing component is bonded to the box body, the upper surface of the top plate and the top surface of the box body are on the same plane. A top sealing paper is provided between the top plate of the blister sealing component and the top of the box body, and the top sealing paper is bonded and fixed to the top plate of the blister sealing component and the top of the box body.

[0013] Furthermore, the inner wall of the box body is provided with hot melt adhesive or blister oil, and the inner wall of the box body is bonded to the blister sealing component by hot melt adhesive or blister oil.

[0014] Furthermore, when the box body is unfolded into a flat surface, hot melt adhesive or blister oil is transferred to the inner wall of the box body through coating, printing, or dispensing by a dispensing machine.

[0015] The present invention also provides a method for producing a packaging box with a blister seal, comprising the following steps:

[0016] S1: Insert the inner mold into the box body until the inner mold abuts against the inner wall of the side panel or side panel extension, so that the inner wall of the box body is bonded to the side panel or side panel extension.

[0017] S2: The heating device on the inner mold is used to heat the hot melt adhesive on the inner wall of the box body, so that the inner wall of the box body is bonded to the side plate or the side plate extension plate.

[0018] Furthermore, the inner mold includes two or more movable molds, which are used to press the side plate or side plate extension plate onto the inner wall of the box body on the same side.

[0019] Furthermore, the outer mold is placed against the side of the top of the box and above the top of the box. Pressure is applied to the outer mold and the inner mold to bond the box body to the side panel or side panel extension, and to position the blister sealing part at the upper sealing point of the box body.

[0020] Through the above technical solutions, the side panel of the blister sealing component is bonded to the inner wall of the top of the box. Since the blister sealing component itself is similar to a box lid structure and has a certain thickness, the bonding area between the side panel and the inner wall of the box is larger, and the structure of the packaging box will be more stable after bonding. At the same time, the packaging box face paper or top sealing face paper covers the blister sealing component and is bonded to it, so the appearance is the same as a traditional packaging box. This structure does not use gray board on the box lid, which is more cost-effective and more environmentally friendly.

[0036] To further illustrate the technology adopted in this invention and its implementation effects, the following describes the application examples of the technology in detail with reference to the preferred embodiments of this invention and their accompanying drawings.

[0037] To further understand the features and technical content of this invention, please refer to the following detailed description and accompanying drawings. The drawings are provided for technical reference and illustration only and are not intended to limit the invention.

[0038] Example 1

[0039] like Figure 1 -7 shows a packaging box with a blister seal, including a box body 2, a base 3, and a blister sealer 1. The box body 2 is a cylindrical box with openings at both ends, and is made of box body paper 22 laminated with a box body base 21, which is either grey board or fiberboard. The blister sealer 1 is located at the top of the box body 2 as the sealing body for the top, and the base 3 is located at the bottom of the box body 2 as the sealing body for the bottom. The blister sealer 1 includes a top plate 11, a positioning part 15 located in the middle of the top plate 11 and extending downwards, and side plates 12 extending downwards from the edge of the top plate 11. The positioning part 15 is mainly used to position the bottle cap, the top plate 11 is located at the top sealing point of the box body 2, and the side plates 11 are bonded to the inner wall of the box body 2.

[0040] The top seal of this type of packaging box eliminates the need for a gray board and directly uses blister sealing component 1 as the sealing body, which can reduce material waste.

[0041] Figure 3 and Figure 4 In the middle, the top plate 11 is square, and there are four side plates 12. The four side plates 12 are connected to the four sides of the top plate 11 and are connected to each other. The side plate extension plates 13 extend from the lower part of the side plates 12. The four side plate extension plates 13 are not connected to each other.

[0042] Figure 4In the middle, the side panel extension plate 13 is provided with a cut 131, and the cut line formed by the cut 131 is a bending cut line or an opening cut line. According to the vacuum forming process, the side panel extension plate 13 is naturally formed during the vacuum forming process. It is basically perpendicular to the side panel 12, so a more perfect edge can be obtained after die cutting. At the same time, the cut 131 is provided to facilitate its bending to be basically parallel to the side panel 12, which is beneficial to the subsequent bonding.

[0043] An opening cutter line can also be provided on the side panel extension plate 13 to facilitate the destruction of the blister seal 1 when opening, thus preventing counterfeiters from recycling it.

[0044] Figure 3 , Figure 4 In this process, the top plate 11 of the blister sealing component 1 is provided with a concave-convex structure 111. Since the blister sealing component 1 itself has low strength, the array of concave-convex structures 111 is beneficial to improving the strength of the top plate 11 of the blister sealing component 1.

[0045] Figure 2 , Figure 5 In this process, the top plate 11 and side plate 12 of the blister sealing component 1 are covered with adhesive paper 14. This arrangement has two advantages: first, the adhesive paper 13 covering the surface of the top plate 11 and side plate 12 makes the blister sealing component 1 look basically the same as an ordinary box lid; second, the adhesive paper 14 covering the surface of the top plate 11 and side plate 12 can cover the uneven structure 151.

[0046] Figure 7 In this process, the side extension plate 13 of the blister sealing component 1 is bonded to the inner wall of the box body 2, so that the connection is deeper into the packaging box body, which is conducive to anti-counterfeiting and anti-tampering.

[0047] Example 2

[0048] Figure 8 and Figure 9 The packaging box shown is different from the first embodiment in that the blister sealing component 1 is first bonded to the inner wall of the box body 2, and then the top sealing paper 4 is used to cover and fix the blister sealing component 1 and the top of the box body 2.

[0049] Figure 8 In this process, after the blister sealing component 1 is bonded to the box body 2, the upper end surface of the top plate 11 and the top surface of the box body 2 are on the same plane. A top sealing paper 4 is provided between the top plate 11 of the blister sealing component 1 and the top of the box body 2, and the top sealing paper 4 is bonded and fixed to the top plate 11 of the blister sealing component and the top of the box body 2.

[0050] Figure 9 In this embodiment, the blister sealing component 1 uses less material.

[0051] Figure 10In this process, the inner wall of the box body is provided with hot melt adhesive 5, or it can be blister oil, which is used to bond the inner wall of the box body 2 to the blister sealing component 1 by heating or high frequency.

[0052] When the box body 2 is unfolded into a flat surface, the hot melt adhesive 5 or blister oil is transferred to the inner wall of the box body 2 by coating, printing, or dispensing adhesive with a dispensing machine.

[0053] Through the above technical solutions, the blister sealing component 1 is bonded to the inner wall of the top of the box body 2. Since the blister sealing component 1 is similar to the structure of a box lid and has a certain thickness, the bonding area is larger, and the structure of the packaging box will be more stable after bonding. At the same time, the face paper 14 or the top sealing face paper 4 covers the blister sealing component 1 and is bonded to it, so the appearance is the same as that of a traditional packaging box. This structure does not use gray board on the box lid, which is more cost-effective and more environmentally friendly.

[0054] like Figure 11 and Figure 12 As shown, the present invention also provides a method for producing a packaging box with a blister seal, comprising the following steps:

[0055] Step S1: Insert the inner mold 6 into the box body 2 until the inner mold 6 abuts against the inner wall of the side plate 12 or the side plate extension plate 13, so that the inner wall of the box body 2 is bonded to the side plate 12 or the side plate extension plate 13.

[0056] Step S2: Use the heating device on the inner mold 6 to heat the hot melt adhesive 5 on the inner wall of the box body 2, so that the inner wall of the box body 2 is bonded to the side panel 12 or the side panel extension plate 13.

[0057] Step S3: Exit the inner mold 6.

[0058] Specifically, the inner mold 6 includes two or more movable molds, which are used to press the side panels 12 or side panel extensions 13 onto the inner wall of the box body 2 on the same side. For example, there are four movable molds, which press the four side panels 12 or side panel extensions 13 onto four different side walls of the box body 2 respectively.

[0059] Step S1 further includes: placing the outer mold 7 against the side of the top of the box body 2 and above the top of the box body 2; applying pressure to the outer mold 7 and the inner mold 6 to bond the box body 2 to the side panel 12 or the side panel extension 13, and positioning the blister sealing component 1 at the upper sealing position of the box body 2. By using the outer mold 7 and the inner mold 6 to clamp the box body 2 to the side panel 12 or the side panel extension 13, the bonding between the box body 2 and the side panel 12 or the side panel extension 13 can be made more secure.

[0060] As described above, those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts of this invention, and all such adjustments, changes, and modifications should fall within the protection scope of the claims of this invention.
