Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealed container technology, and in particular to a threaded child-proof container. Background Technology
[0002] Many existing sealed plastic containers typically consist of a box and a lid, connected by threads. However, these containers lack child-proof design, allowing children to easily unscrew the lid and access the contents. When the container contains medications, cleaning agents, or other items unsuitable for children, opening the container exposes the child directly to these substances, posing a significant risk of accidental ingestion or contact with the contents and a potential threat to their health. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a threaded, child-proof container.
[0004] The purpose of this utility model is achieved through the following technical solution: a threaded child-proof container, including a top cover, a box body, and an elastically compressible sealing gasket, the sealing gasket being installed in the top cover, and a threaded structure being provided on the outer side of the box body; a threaded body being provided on the inner side of the top cover to cooperate with the threaded structure, a buckle being provided at the front end of the threaded extension direction of the threaded body, and a second groove being formed between the buckle and the threaded body; a first limiting body and a second limiting body being provided on the threaded structure, and a first groove being provided between the first limiting body and the second limiting body; when the top cover and the box body are locked, the buckle engages in the first groove, and the first limiting body engages in the second groove.
[0005] Preferably, the first limiting body is provided with a guide slope; the buckle provided on the upper cover enters the first slot through the guide slope to achieve locking between the upper cover and the box body.
[0006] Preferably, the buckle is provided with an arc-shaped surface; when the buckle passes over the first limiting body, the arc-shaped surface on the buckle contacts the guide slope on the first limiting body.
[0007] Preferably, the sealing gasket includes a central protrusion, an annular recess around the central protrusion, and a flange around the annular recess; the sealing gasket is provided with an annular sealing surface for sealing and engaging with the inner wall surface of the box.
[0008] Preferably, the lower end of the annular sealing surface is provided with an inlet cone surface.
[0009] Preferably, the top cover has a recessed positioning part at its center, and the central protrusion of the sealing gasket has a positioning groove corresponding to the recessed positioning part. The top cover fits against the upper surface of the central protrusion, and the recessed positioning part is embedded in the positioning groove.
[0010] Preferably, the inner side of the top cover is provided with a sealing gasket limiting boss for fixing the sealing gasket.
[0011] Preferably, both the top cover and the box body are made of plastic.
[0012] The beneficial effects of this utility model are as follows: After the top cover is locked, it cannot be easily unscrewed by children. Due to their small strength and lack of operating experience, children find it difficult to complete the operation of "pressing down first and then rotating", making it impossible for the buckle and the first limiting body to disengage from the slot, thus making it difficult to open the container. This serves to prevent children from opening the container, avoiding children from contacting items that are not suitable for contact (such as medicines, cleaning agents, etc.), and reducing the safety risks of accidental ingestion or accidental contact.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0019] like Figures 1 to 4As shown, a threaded child-proof container includes a top cover 1, a box body 2, and an elastically compressible sealing gasket 3. The sealing gasket 3 is installed in the top cover 1. A threaded structure 4 is provided on the outer side of the box body 2. A threaded body 8 that mates with the threaded structure 4 is provided on the inner side of the top cover 1. A buckle 9 is provided at the front end of the threaded extension direction of the threaded body 8. A second groove 10 is formed between the buckle 9 and the threaded body 8. A first limiting body 6 and a second limiting body 7 are provided on the threaded structure 4. A first groove 5 is provided between the first limiting body 6 and the second limiting body 7. When the top cover 1 and the box body 2 are locked, the buckle 9 is engaged in the first groove 5, and the first limiting body 6 is engaged in the second groove 10.
[0020] In this invention, when installing the top cover 1, simply rotate the top cover 1 in the direction of thread tightening. When the buckle 9 rotates to the position of the first slot 5 on the box body 2, the buckle 9 will engage in the first slot 5, and at the same time, the first limiting body 6 will engage in the second slot 10 on the top cover 1. Under the limiting action of the first limiting body 6 and the second limiting body 7, the buckle 9 locks the top cover 1 and cannot be easily unscrewed. When it is necessary to unscrew the top cover 1, first press the top cover 1 downward to make the top cover 1 move axially relative to the box body 2, thereby causing the buckle 9 on the top cover 1 to disengage from the first slot 5 and the first limiting body 6 to disengage from the second slot 10. Then, rotate the top cover 1 to unscrew it.
[0021] The sealing gasket 3 is elastically compressible. When the container is locked, the elastically compressed sealing gasket 3 deforms under the axial pressure of the top cover 1 and the box body 2, tightly filling the gap between them. This effectively prevents external substances such as air, moisture, and dust from entering the container, while also preventing leakage of liquids, powders, and other substances stored inside. Even if the container experiences slight vibrations or temperature changes during transportation or storage, causing minor deformation of components, the sealing gasket 3 can adaptively adjust through its own elasticity to maintain a stable sealing effect. Furthermore, when opening the top cover 1, the buckle 9 needs to be disengaged from the slot by "pressing the top cover 1 downwards." The elastic sealing gasket 3 provides a buffer space during the pressing process and provides movement space between the top cover 1 and the box body 2: when pressed, the sealing gasket 3 is compressed, providing leeway for the axial relative movement of the top cover 1 and the box body 2, ensuring that the buckle 9 and the limiting body can smoothly disengage from the slot; after releasing the press, the elastic rebound force of the sealing gasket 3 can assist the top cover 1 in resetting, ensuring the structural stability in the locked state.
[0022] In this invention, once the top cover 1 is locked, it cannot be easily unscrewed by a child. Due to their limited strength and lack of experience, children find it difficult to complete the complex operation of "pressing down first and then rotating," making it impossible for the buckle 9 and the first limiting body 6 to disengage from the slot. This makes it difficult to open the container, thus preventing children from opening it and avoiding contact with items that are not suitable for children to touch (such as medicines, cleaning agents, etc.), thereby reducing the safety risks of accidental ingestion or contact.
[0023] The first limiting body 6 is provided with a guide slope 21; the buckle 9 provided on the upper cover 1 enters the first slot 5 through the guide slope 21 to achieve locking between the upper cover 1 and the box body 2. The guide slope 21 provides a stable guide for the buckle 9 to enter the first slot 5, so that the buckle 9 is subjected to more even force during the sliding process, and avoids deformation or wear of the parts due to forced insertion.
[0024] The buckle 9 has an arc-shaped surface 20. When the buckle 9 passes over the first limiting body 6, the arc-shaped surface 20 of the buckle 9 contacts the guide slope 21 of the first limiting body 6. The contact between the arc-shaped surface 20 and the guide slope 21 is a smooth contact between a curved surface and a slope. As the buckle 9 slides along the guide slope 21 and enters the first slot 5, this contact method can greatly reduce the friction between the two, making the process of the buckle 9 sliding into the first slot 5 less resistant, reducing the feeling of jamming during operation, and making it easier for adults to lock the top cover 1.
[0025] Specifically, the sealing gasket 3 includes a central protrusion 13, an annular recess 14 surrounding the central protrusion 13, and a flange 15 surrounding the annular recess 14. The sealing gasket 3 also has an annular sealing surface 16 for sealing against the inner wall surface 18 of the container 2. When the top cover 1 is tightened onto the container 2, the annular sealing surface 16 fits tightly against the inner wall surface 18 of the container 2, thus sealing the contents of the container. The annular recess 14, located between the central protrusion 13 and the flange 15, has a certain elastic deformation space, giving the sealing gasket 3 good overall elasticity. When the top cover 1 is tightened, the annular recess 14 can absorb assembly errors between the top cover 1 and the container 2 through its own deformation, avoiding sealing failure due to localized stress concentration. For temperature changes or slight container deformation, the elasticity of the annular recess 14 can adaptively adjust the sealing pressure, maintaining long-term sealing stability and preventing leakage of internal substances due to environmental changes.
[0026] The lower end of the annular sealing surface 16 is provided with an inlet cone surface 17. The inlet cone surface 17 is provided to guide the sealing gasket 3 into the housing 2 and form a tight fit between the two.
[0027] The top cover 1 has a recessed positioning part 12 in the center, and the central protrusion 13 of the sealing gasket 3 has a positioning groove 19 corresponding to the recessed positioning part 12. The upper end of the central protrusion 13 is attached to the top cover 1, and the recessed positioning part 12 is embedded in the positioning groove 19.
[0028] The inner side of the top cover 1 is provided with a sealing gasket limiting protrusion 11 for fixing the sealing gasket 3. The sealing gasket 3 is fixed by the sealing gasket limiting protrusion 11.
[0029] In this embodiment, both the top cover 1 and the box body 2 are made of plastic.
[0030] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
