Specific embodiments

[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0026] As Figures 1 to 6 shown, this embodiment provides a quickly sealed carton, including a box body 1. The box body 1 is a square carton with one end open. The box body 1 is made of corrugated cardboard. First box covers 2 are respectively arranged above the corresponding side walls of the box body 1, and second box covers 3 are respectively arranged above the other two opposite side walls of the box body 1. When sealing the box body 1, first fold the second box cover 3 inwards and cover it on the box body 1, and then fold the first box cover 2 inwards and cover it on the box body 1. The first box cover 2 is located above the second box cover 3. The box body 1, the first box cover 2, and the second box cover 3 together form a carton structure. Both the first box cover 2 and the second box cover 3 include corrugated core paper 4 and cardboard 11. As Figures 3 to 4As shown in the figure, the corrugated cardboard 4 has a three-layer structure, with the corrugated core paper 4 located between two cardboard sheets 11. Inside the first box cover 2, multiple diffusion grooves 5 are provided near the free end. Small holes (not shown in the figure) corresponding to the multiple diffusion grooves 5 are provided on the cardboard sheet 11 on the inner side of the first box cover 2. Each diffusion groove 5 corresponds to at least one small hole. A glue packet 6 filled with glue is installed from the gap of the corrugated core paper 4 at the free end of the first box cover 2 into the diffusion groove 5. The diameter of the small hole is smaller than that of the glue packet 6. The glue packet 6 is made of gelatin and can also be prepared from corresponding materials that meet the preparation requirements, such as plastic materials. The glue packet 6 is a bag-like structure filled with glue and sealed. A limiting paper strip 7 is provided below the diffusion groove 5, and multiple glue packets 6 are respectively located on the limiting paper strip 7 in the corresponding diffusion groove 5. During installation, the glue packet 6 is sleeved on a small steel pipe (or other rigid cylindrical structures. To avoid the glue packet 6 being crushed and broken during installation, the cylindrical structure needs to have a certain hardness and wear resistance). The glue packet 6 is installed into the diffusion groove 5 through the gap of the corrugated core paper 4 via the small steel pipe. When the small steel pipe extends into the corresponding diffusion groove 5, air is blown from the end of the small steel pipe (the small steel pipe is connected to the outlet pipe orifice of the air supply device) to blow the glue packet 6 out of the small steel pipe. Then, the glue packet 6 falls into the diffusion groove 5 to complete the installation. After the installation is completed, the small steel pipe is withdrawn, and the second box cover 3 and the first box cover 2 are folded inwardly towards the inside of the box body 1 in sequence. After the second box cover 3 and the first box cover 2 are folded by 90°, at the corresponding position of the glue packet 6 on the outer side of the first box cover 2, the glue in the glue packet 6 diffuses in the diffusion groove 5 and oozes out from the first box cover 2 downward. The small holes facilitate the oozing of the glue. The oozed glue contacts the second box cover 3, thereby adhering the first box cover 2 and the second box cover 3 together to complete the sealing of the cardboard box.

[0027] Bar-shaped cardboard sheets 8 are fixedly provided on both sides of the second box cover 3. A bar-shaped groove 9 is provided on the inner side of the connection part between the first box cover 2 and the box body 1. The bar-shaped groove 9 matches the bar-shaped cardboard sheets 8. When the second box cover 3 is folded inwardly and covered on the box body 1, the bar-shaped cardboard sheets 8 are located in the corresponding bar-shaped grooves 9. The bar-shaped grooves 9 limit and support the bar-shaped cardboard sheets 8, thereby limiting the second box cover 3 and effectively preventing the first box cover 2 and the second box cover 3 from folding inwardly continuously when the glue packet 6 inside the first box cover 2 is pressed.

[0028] Support cardboard sheets 10 are provided at the four corners inside the box body 1. The cross-section of the support cardboard sheets 10 is L-shaped and fits the four corners inside the box body 1. The support cardboard sheets 10 further strengthen the support effect on the second box cover 3, effectively ensuring that when the glue packet 6 inside the first box cover 2 is pressed, the first box cover 2 and the second box cover 3 will not fold inwardly towards the inside of the box body 1 continuously.

[0029] As an implementable embodiment, the box body 1 can also be a square cardboard box with openings at both ends.

[0030] As an implementable mode, the glue packet 6 can be prepared by the following method: The raw materials of the glue packet (gelatin, plasticizer, and water are mixed in a ratio of 1:0.5:1) are heated and melted to prepare a malleable thin gel sheet. The two gel sheets are respectively spread on the roller surface with grooves, and the malleability of the gel sheets is utilized to make them closely adhere to the inner wall of the grooves. Subsequently, when the two gel sheets come into contact, a quantitative amount of glue is injected into the grooves. Then, the gel sheets are heated, and the two gel sheets are bonded together to form a plurality of complete glue packets 6. Subsequently, the individual glue packets 6 are cut off and then dried to complete the preparation of the glue packets 6.

[0031] During use, first, a strip-shaped groove 9 is machined on the inner side of the connection part between the first box cover 2 and the box body 1. Strip-shaped cardboard 8 is fixed on both sides of the second box cover 3 (that is, two strip-shaped cardboard 8 are cut out on both sides of the second box cover 3). The strip-shaped cardboard 8 is integrally cut and made with the second box cover 3. A diffusion groove 5 is machined inside the first box cover 2, and a limit paper strip 7 is fixedly arranged at one end of the diffusion groove 5 close to the box body 1. Subsequently, the corrugated core paper 4 is bonded to the cardboard 5.

[0032] After the cardboard box is processed, the glue packet 6 is installed in the corresponding diffusion groove 5 through a small steel pipe or the like from the gap of the corrugated core paper 4 of the first box cover 2. Then, the steel pipe or the installation column is pulled out of the first box cover 2, and support cardboard 10 is fixedly arranged or movably arranged at the four corners inside the box body 1.

[0033] When sealing the cardboard box, first, the second box cover 3 is folded inward to cover the opening of the box body 1, so that the strip-shaped cardboard 8 on both sides of the second box cover 3 enters the strip-shaped groove 9. At this time, the inner side of the second box cover 3 is in contact with the top surface of the support cardboard 10, so that the second box cover 3 is further supported by the support cardboard 10. Subsequently, the first box cover 2 is folded inward to cover the second box cover 3, and the position corresponding to the glue packet 6 on the outer side of the first box cover 2 is pressed. As a result, the glue packet 6 is broken, and the glue in the glue packet 6 flows and diffuses in the diffusion groove 5 and diffuses inward and penetrates onto the second box cover 3, adhering the first box cover 2 and the second box cover 3 together to complete the sealing of the cardboard box.

[0034] The above-described embodiments are only the preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
