Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box with waterproof function. Background Technology

[0002] Packaging boxes are typically used to package products, thereby facilitating their subsequent transportation, storage, and sale. In the food industry, there are many types of packaging boxes, and the specifications and shapes of the packaging boxes required vary depending on the type of food.

[0003] When packaging puffed foods, moisture resistance is crucial for the packaging box. If there are any flaws in the waterproof or moisture-proof function during storage, the taste of the puffed food can be easily ruined. Most existing puffed food packaging uses plastic bags for protection, or fills the plastic bags with inert gas to improve the moisture resistance of the puffed food.

[0004] In the packaging process of biscuits, they are usually packaged in multiple independent small bags, with a desiccant placed in each bag to absorb moisture. Although this packaging method can keep the biscuits dry to a certain extent, the desiccant loses its effectiveness after absorbing a certain amount of moisture, and the use of desiccant also increases packaging costs. Therefore, improvements are needed. Utility Model Content

[0005] The main purpose of this utility model is to propose a waterproof packaging box, which aims to provide a packaging box for puffed food that is easy to waterproof and moisture-proof.

[0006] To achieve the above objectives, this utility model proposes a waterproof packaging box, including a box body and a lid. The box body is provided with a receiving cavity, and the upper end of the box body is provided with a fitting area. The lid is placed on the box body and is bonded to the fitting area to cover the receiving cavity to form a waterproof sealed cavity.

[0007] Specifically, a connecting platform is formed at the upper end of the box body, and an adhesive strip is provided on the connecting platform. The cover body is tightly attached to the connecting platform through the adhesive strip.

[0008] Specifically, the adhesive strip is located in the middle of the connecting platform. After the cover is closed with the connecting platform, the adhesive strip forms a sealing part that cooperates with the receiving cavity on the inner side of the adhesive strip and an opening part on the outer side of the adhesive strip.

[0009] Specifically, the adhesive strip includes a plurality of first adhesive strip portions and a plurality of second adhesive strip portions, with adjacent first adhesive strip portions spaced apart to form notches, and the second adhesive strip portions located on the front or rear side of the first adhesive strip portions and covering the notches to form a closed loop.

[0010] Specifically, the edge of the cover is provided with an arc-shaped bend, which bends downward toward the bottom of the cover.

[0011] Specifically, the box body is provided with at least two receiving grooves of the same volume, and adjacent receiving grooves are spaced apart to form the receiving cavity.

[0012] This utility model provides a container cavity on the box body to hold puffed food. The lid is then bonded to the box body to form a waterproof and sealed cavity. This waterproof and sealed cavity protects the puffed food from water, eliminating the need to fill the cavity with inert gas or place a desiccant, thus reducing packaging costs.

[0022] like Figures 1 to 5 As shown, a waterproof packaging box includes a box body 10 and a lid 20. The box body 10 has a receiving cavity, and the upper end of the box body 10 has a fitting area. The lid 20 is placed on the box body 10 and is bonded to the fitting area to cover the receiving cavity, forming a waterproof sealed cavity. By providing a receiving cavity in the box body 10 to accommodate puffed food, and then bonding the lid 20 to the box body 10, a waterproof sealed cavity is formed on the box body 10 to protect the puffed food from water damage. This eliminates the need for additional filling of the waterproof sealed cavity with inert gas or placing a desiccant, thus reducing packaging costs.

[0023] A connecting platform 11 is formed at the upper end of the box body 10, and an adhesive strip is provided on the connecting platform 11. The cover 20 is tightly attached to the connecting platform 11 through the adhesive strip. In this embodiment, a connecting platform 11 is formed at the upper end of the box body 10. By providing an adhesive strip on the connecting platform 11, it is easier for the cover 20 to be stably bonded to the connecting platform 11 through the adhesive strip.

[0024] The adhesive strip is located in the middle of the connecting platform 11. After the cover 20 is closed with the connecting platform 11, the adhesive strip forms a sealing part that mates with the receiving cavity on the inner side of the adhesive strip and an opening part on the outer side of the adhesive strip. In this embodiment, the adhesive strip is located in the middle of the connecting platform 11. When the cover 20 is attached to the connecting platform 11, the portion of the cover 20 located on the inner side of the adhesive strip mates with the receiving cavity to form a sealing part, thereby forming a waterproof sealed cavity on the box body 10. At the same time, the portion on the outer side of the adhesive strip forms an opening part, which facilitates opening the waterproof sealed cavity through the opening part, thus improving the user experience.

[0025] The adhesive strip includes several first adhesive strip portions 13 and several second adhesive strip portions 14. Adjacent first adhesive strip portions 13 are spaced apart to form notches. The second adhesive strip portions 14 are located on the front or rear side of the first adhesive strip portions 13 and cover the notches to form a closed loop. In this embodiment, the first adhesive strip portions 13 and the second adhesive strip portions 14 cooperate to form a closed-loop adhesive strip. When the cover 20 is attached to the connecting platform 11, an irregularly shaped waterproof sealing cavity can be formed by the first adhesive strip portions 13 and the second adhesive strip portions 14, which facilitates the handling of air pressure differences when the product is transported from low-altitude areas to high-altitude areas.

[0026] The edge of the cover 20 is provided with an arc-shaped bend, which bends downward toward the bottom of the cover 20. In this embodiment, the arc-shaped bend is provided on the edge of the cover to facilitate a tight fit between the edge of the cover 20 and the connecting platform 11, thereby improving the dustproof effect of the cover 20.

[0027] The box body 10 is provided with at least two receiving grooves 15 of the same volume, and adjacent receiving grooves 15 are spaced apart to form receiving cavities. In this embodiment, at least two receiving cavities are provided on the box body 10, which facilitates the separate placement of puffed food and improves the versatility of the placement arrangement of the box body 10.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
