Description

Technical Field

[0001] This utility model relates to a tinplate sealing box made by stamping tinplate into a packaging box, especially a moisture-proof and damp-proof sealing box. Background Technology

[0002] Tinplate packaging, with its excellent sealing, light-blocking, sturdiness, diverse styles, and exquisite printing, is widely used in the packaging of food, daily necessities, pharmaceuticals, instruments, and industrial products. For items requiring moisture protection, such as medicines, tea, and cigarettes, moisture-proof and airtight boxes are needed to prevent mold growth and damage. However, the fit between the lid and body of tinplate boxes often has gaps or gaps. This is partly due to manufacturing processes that make a perfect seal difficult, and partly because an overly tight fit makes it difficult to open the lid. Therefore, current tinplate boxes are insufficient to prevent outside air from entering, often leading to mold growth on stored items. Utility Model Content

[0003] This utility model provides a tinplate sealing box that overcomes the shortcomings of the prior art. It has a simple structure, is easy to manufacture, and has strong sealing performance.

[0004] The technical solution adopted by this utility model is: a tinplate sealing box, comprising a lid and a box body fastened together; characterized in that the box body is composed of a box body side wall and a box body bottom surface, the box body side wall has a step formed by bending, the step dividing the box body side wall into an upper part and a lower part, the upper part of the box body side wall is provided with a latch that cooperates with the box lid, the upper part of the box body side wall extends inclined inward to form the upper edge of the box body; the corresponding box lid is composed of a box lid top surface and a box lid side wall, the bottom edge of the box lid side wall has an inward rolled edge that cooperates with the latch on the box body side wall; the inner surface of the box lid top surface is provided with a circumferential elastic sealing ring that cooperates with the box body side wall.

[0005] In the aforementioned tinplate sealing box, the rolled edge of the box lid is located between the step and the latch on the side wall of the box body.

[0006] In the aforementioned tinplate sealing box, the inner surface of the top surface of the box cover is provided with a circumferentially inwardly opening groove, and the elastic sealing ring is located in the groove.

[0007] The aforementioned tinplate sealing box has an inwardly rolled edge at the top of the upper part of the side wall of the box body, which can abut against the elastic sealing ring on the inner surface of the top surface of the box lid.

[0008] The aforementioned tinplate sealing box has four symmetrically arranged latches on the upper side wall of the box.

[0009] This invention offers the following advantages: The elastic sealing ring, formed by the inclined extension of the upper sidewall of the box towards the inside of the box and the roll edge of the box that abuts against the inner surface of the lid, achieves a tight seal between the lid and the box body. This provides strong sealing, preventing moisture and water damage, and ensuring the safety of the contents. In particular, the upper edge of the box body, formed by the inclined extension of the upper sidewall, provides elasticity when it abuts against the inner surface of the lid, further enhancing the seal and ensuring long-term airtightness.

[0016] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The illustration shows a tinplate sealing box according to the present invention, comprising a lid 1 and a body 2, wherein the lid 1 can be fastened onto the body 2. The lid 1 consists of a top surface 11 and a side wall 12. The bottom edge of the side wall 12 has an inwardly rolled edge 121. The inner surface of the top surface 11 has a circumferentially inwardly opening groove 111, and an elastic sealing ring 3, which can be made of rubber, is provided in the groove 111. The box body 2 includes a side wall 21, which has a step 211 formed by bending. The step 211 divides the side wall 21 into an upper part 21A and a lower part 21B. The upper part 21A extends inward to form an upper edge 212. The top of the upper part 21A has an inward rolled edge 213. The upper part 21A is provided with a latch 214 that cooperates with the lid. There are four latches 212 symmetrically arranged on the upper part 21A. Thus, when the lid 1 is fastened onto the body 2, the lid's rolled edge 121 is located between the step 211 and the latch 212 on the side wall 21 of the body and engages with the latch 214 to lock the lid 1 onto the body 2. At this time, the body's rolled edge 213 abuts against the elastic sealing ring 3 on the inner surface of the lid's top surface 11, achieving a sealed fit between the lid 1 and the body 2. Because the upper edge 212 of the body, formed by the inclined extension of the upper part 21A of the side wall into the body, is elastically deformed by the pressure of the lid 1, and due to the plasticity of the elastic sealing ring 3, the body's rolled edge 213 has a certain elasticity when it abuts against the inner surface of the lid's top surface 11, resulting in better sealing.

[0019] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
