Description

Technical Field

[0001] This utility model relates to the field of sealed container technology, especially to the field of nicotine and oral cigarette packaging, and particularly to a sealed round container that can be safely opened and has the purpose of sealing and preserving freshness. Background Technology

[0002] Many existing round plastic containers lack child-proof designs, making them easy for children to open and access the contents. If the container contains medications, cleaning agents, or other items unsuitable for children, opening it exposes the child to these substances, posing a significant risk of accidental ingestion or contact with the contents and potentially threatening their health. Furthermore, existing round plastic containers generally suffer from poor sealing, leading to leakage and hindering the preservation of the contents. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing sealed containers having no child-proof opening and poor sealing performance, and to provide a safe-to-open sealed container.

[0004] The purpose of this utility model is achieved through the following technical solution: a safe-opening sealed container, including a can body, a lid, and a sealing gasket, wherein a snap-fit ​​mechanism is provided between the can body and the lid, and the sealing gasket is disposed inside the lid; a toothed structure is provided on the outer side of the can body; the annular inner wall of the lid is divided into a contact area and a non-contact area, and a contact protrusion that cooperates with the toothed structure is provided in the contact area; during the rotation of the lid, the contact protrusion contacts the toothed structure and produces a sound when it passes through the toothed structure; when the lid is rotated to the open position, the toothed structure enters the non-contact area; a first tactile marker is provided on the outer side of the lid, and a second tactile marker is provided on the outer side of the can body; when the lid is in the open state, the first tactile marker on the lid aligns with the second tactile marker on the can body.

[0005] Preferably, the latching mechanism includes a latching protrusion disposed on the outside of the can body, the latching protrusion being disposed along the circumference of the can body, a first passage area being disposed between adjacent latching protrusions, and a second passage area being disposed on the latching protrusion; a first latching body corresponding to the first passage area and a second latching body corresponding to the second passage area are disposed on the inside of the cover.

[0006] Preferably, a limiting surface is provided on one side of the first passage area.

[0007] Preferably, the inner side of the cover is provided with a gasket limiting boss for limiting the gasket.

[0008] Preferably, the sealing gasket includes a central raised area, an annular recessed area around the central raised area, and a flange structure around the annular recessed area; the side of the sealing gasket is provided with a sealing mating surface that mates with the inner wall of the tank.

[0009] Preferably, the lower end of the sealing mating surface is provided with an inlet cone surface.

[0010] Preferably, the tank body is provided with an annular cavity, and the bottom of the tank body is provided with a sealing ring for sealing the cavity.

[0011] Preferably, the upper end of the cover is provided with anti-slip particles.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, a latching mechanism is provided between the can and the lid. The latching mechanism requires the user to rotate the lid to a specific angle position in order to open the lid. This increases the difficulty of opening the lid, making it difficult for children to open the lid, thereby preventing children from accidentally swallowing or touching the contents of the container.

[0014] 2. This utility model can effectively help visually impaired users open the lid of the container conveniently and smoothly through tactile and sound guidance, which greatly facilitates the use of such users and is very friendly to the visually impaired population.

[0015] 3. This utility model includes a sealing gasket inside the lid. After the lid is installed on the tank, the sealing mating surface of the gasket extends into the tank and fits tightly against the inner wall of the tank, thereby achieving a sealing effect. The annular recessed area is located between the central raised area and the flange structure, and has a certain elastic deformation space: when the lid is tightened, the recessed area can absorb the assembly error between the lid and the tank through its own deformation, avoiding sealing failure caused by local stress concentration; for temperature changes or slight deformation of the container, the elasticity of the recessed area can adaptively adjust the sealing pressure, maintain long-term sealing stability, and prevent external air from entering the interior and causing deterioration.

[0023] 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.

[0024] like Figures 1 to 6 As shown, a safe-opening sealed container includes a can body 2, a cover 1, and a sealing gasket 5. A snap-fit ​​mechanism is provided between the can body 2 and the cover 1, and the sealing gasket 5 is disposed inside the cover 1. A toothed structure 12 is provided on the outer side of the can body 2. The annular inner wall 24 of the cover 1 is divided into a contact area and a non-contact area. A contact protrusion 16 that cooperates with the toothed structure 12 is provided in the contact area. During the rotation of the cover 1, the contact protrusion 16 contacts the toothed structure 12 and produces a sound when it passes by the toothed structure 12. When the cover 1 is rotated to the open position, the toothed structure 12 enters the non-contact area. A first tactile marker 3 is provided on the outer side of the cover 1, and a second tactile marker 4 is provided on the outer side of the can body 2. When the cover 1 is in the open state, the first tactile marker 3 on the cover 1 aligns with the second tactile marker 4 on the can body 2.

[0025] In this invention, the lid 1 and the can 2 are connected by a snap-fit ​​mechanism. The lid 1 needs to be rotated to a specific angle and a certain force is required to separate the lid 1 from the can 2. A contact protrusion 16 is provided in the contact area, while no contact protrusion 16 is provided in the non-contact area. During the rotation of the lid 1, if the lid 1 is not yet close to the open position, the toothed structure 12 on the outer side of the can 2 will be located in the contact area on the lid 1. When the lid 1 rotates, the contact action between the contact protrusion 16 and the toothed structure 12 will produce a "clicking" sound, which will alert the user that the lid 1 has not yet been rotated to the open position. When the lid 1 is about to be opened, the toothed structure 12 on the outer side of the can 2 will be located in the non-contact area on the lid 1. Since there is no contact protrusion 16 in the non-contact area, the toothed structure 12 on the outer side of the can 2 will not be able to contact the contact protrusion 16, so no "clicking" sound will be produced. The sound will disappear, thus alerting the user that the lid 1 is about to be rotated to the open position. At this time, the user only needs to rotate it within a small range around this angle to find the open position. Meanwhile, a first tactile marker 3 and a second tactile marker 4 are respectively provided on the lid 1 and the can 2. The first tactile marker 3 and the second tactile marker 4 are raised or recessed structures that can be identified by touch. When the sound disappears during the rotation of the lid 1, the user can help and guide the lid 1 to rotate accurately to the open position by touching the first tactile marker 3 and the second tactile marker 4. When the first tactile marker 3 on the lid 1 is aligned with the second tactile marker 4 on the can 2 (this state can be confirmed by touch), the lid 1 reaches the open position. At this time, the user can open the lid 1 by applying a certain pulling force.

[0026] This invention effectively helps visually impaired users to open the lid 1 of a container easily and smoothly through tactile and auditory guidance, reducing the difficulty of opening and greatly facilitating its use. It is very user-friendly for visually impaired people.

[0027] The latching mechanism includes latching protrusions 8 on the outer side of the can body 2, which are arranged circumferentially around the can body 2. A first passage area 9 is provided between adjacent latching protrusions 8, and a second passage area 11 is provided on each latching protrusion 8. The inner side of the cover 1 has a first latching body 14 corresponding to the first passage area 9 and a second latching body 15 corresponding to the second passage area 11. A limiting surface 10 is provided on one side of the first passage area 9. When the cover 1 rotates, the first latching body 14 must first align with the first passage area 9, and the second latching body 15 must simultaneously align with the second passage area 11 (a specific area on a single protrusion). Both must simultaneously meet the positional matching requirement to connect or separate the cover 1 from the can body 2. This structure increases the operational complexity of opening. Children, due to limited cognitive abilities and insufficient fine motor skills, find it difficult to accurately control the rotation of the cover 1 to the open position, thus effectively preventing children from accidentally opening the cover. The buckle protrusions are continuously arranged around the circumference of the can body 2. When the opening angle is not reached, the buckle protrusions will form a circumferential block on the first and second buckle bodies 15, so that the cover body 1 cannot be rotated or separated axially at will, ensuring the connection is firm in the closed state and avoiding accidental opening due to accidental contact.

[0028] The inner side of the cover 1 is provided with a gasket limiting boss 13 for limiting the gasket 5. The edge of the gasket 5 is held in place by the gasket limiting boss 13, so that the gasket 5 can be stably installed in the cover 1.

[0029] like Figure 5 As shown, the sealing gasket 5 includes a central raised area 17, an annular recessed area 18 surrounding the central raised area 17, and a flange structure 19 surrounding the annular recessed area 18. The side of the sealing gasket 5 has a sealing mating surface 20 that mates with the inner wall 22 of the tank. After the cover 1 is installed on the tank 2, the sealing mating surface 20 on the side of the sealing gasket 5 extends into the tank 2 and fits tightly against the inner wall 22, thereby achieving a sealing effect on the tank 2. The annular recessed area 18 is located between the central raised area 17 and the flange structure 19, and has a certain elastic deformation space: when the cover 1 is tightened, the recessed area can absorb the assembly error between the cover 1 and the tank 2 through its own deformation, avoiding sealing failure caused by local stress concentration; for temperature changes or slight deformation of the container, the elasticity of the recessed area can adaptively adjust the sealing pressure, maintain long-term sealing stability, and prevent leakage of internal substances due to environmental changes.

[0030] The lower end of the sealing mating surface 20 is provided with an inlet cone surface 21. The inlet cone surface 21 can guide the sealing gasket 5 to form a tight fit with the tank body 2.

[0031] The tank body 2 has an annular cavity 23 inside, and a sealing ring 6 is provided at the bottom of the tank body 2 to seal the cavity 23. By providing the cavity 23 inside the tank body 2, the heat preservation effect of the tank body 2 can be improved. At the same time, this hollow structure also reduces the weight of the tank body 2 and saves materials.

[0032] The upper end of the cover 1 is provided with anti-slip particles 7. When the cover 1 is rotated, the anti-slip particles can play a good anti-slip role.

[0033] 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.
