Description

Technical Field

[0001] The invention relates to the technical field of sealed container structures, and in particular to a sealed container structure with high efficiency. Background Art

[0002] The various container packaging commonly used in catering retail stores has defects in its sealing solutions; these container products usually use easy-tear labels to indicate that they have not been opened. However, this non-omnidirectional sealing method cannot ensure the sealing of the container after the lid is closed, and can only indicate that the lid has not been fully opened. Another common practice is to use plastic paper to seal the package by high-temperature pressing after filling the food and beverages to achieve a sealing effect. However, this method is not only inconvenient for consumers to open, but may also release plasticizers due to high temperature, posing a potential threat to the health of consumers, especially children. In addition, this method is not hygienic or aesthetically pleasing, and it adds additional equipment and tool costs and packaging process time costs.

[0003] After searching, the application scheme of Chinese patent application No. 202222471151.8 discloses a milk tea cup, including a milk tea cup body, a cup cover, a sealing ring, a cup cover snap-on plate and a milk tea cup body snap-on plate. The sealing ring is arranged on the cup cover. The cup cover snap-on plate is arranged on the sealing ring. The milk tea cup body snap-on plate is arranged on the milk tea cup body. The cup cover snap-on plate and the milk tea cup body snap-on plate are snap-on correspondingly. The milk tea cup in the above-mentioned document has the following shortcomings: although it can meet the needs of filling, the sealing ability is still insufficient, and in practical applications, it is not possible to distinguish whether it has been opened well, which needs to be improved.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention can achieve structural sealing based on the cooperation of the elastic snap-fitting part and the edge of the outward-turned container by providing structures such as a container body, a container cover body and an annular limiting part. At the same time, the design of the annular limiting part can have a reinforcement effect, preventing the elastic snap-fitting part from being separated from the edge of the outward-turned container, thereby improving the firmness of the structure. In addition, since structures such as brittle-break notches are provided, during disassembly, the annular limiting part can be destroyed by destroying the brittle-break notches, thereby releasing the deformation restriction on the annular cover edge, so that force can be applied to deform the annular cover edge, so that the elastic snap-fitting part is separated from the edge of the outward-turned container to complete the disassembly.

[0026] 2. The solution of the present invention requires the destruction of the brittle-break notch during disassembly, and this process is irreversible, so it is easy to distinguish whether the container structure has been opened.

[0027] 3. The present invention provides a cover stopper and a semi-enclosed notch, and can fold the cover stopper downward or upward by destroying the semi-enclosed notch, so as to facilitate use.

[0028] 4. The present invention adopts a multi-layer cover structure by providing an inner cover body and an outer cover body. When in use, the folding portion can be folded based on the folding groove to expose the first opening, which is convenient for use. The outer cover body can be directly removed for use, or the outer cover body and the inner cover body can be removed for use together, which has high flexibility in use. When removing the outer cover body, the brittle fracture notch needs to be destroyed, which can facilitate the user to intuitively observe whether the container has been opened, and is highly practical. Moreover, since the annular cover edge itself has a certain structural strength, it can still maintain a certain sealing ability through the buckling of the elastic clamping portion and the edge of the outward-turned container, which is convenient for multiple uses.

[0029] 5. The present invention provides structures such as a brittle connection portion. Since the folding portion is connected to the annular limiting portion, when opening is required, the brittle connection portion must be destroyed to break the annular limiting portion. In this way, it is convenient to distinguish whether the container has been opened and used, thereby improving practicality.

[0030] 6. The present invention provides a split annular cover edge, which can destroy the baffle portion through the brittle fracture notch when it needs to be opened, thereby releasing the limit of the opposite hook portion, so that the folding portion can be flipped over for use; in addition, the destruction of the baffle portion makes the annular cover edge easier to deform, so that the annular cover edge can be conveniently removed from the edge of the outward-folding container; this method can help users distinguish whether the container has been opened, thereby improving practicality.

[0031] 7. Since the outer cover and the inner cover are connected by a connecting piece, the outer cover can be opened and used according to needs, or the connecting piece can be destroyed to remove the outer cover; this solution provides a variety of different usage methods and has high flexibility.

The elastic snap-fitting parts 8 are inclined toward the container body 1 along the vertical downward direction, and the plurality of elastic snap-fitting parts 8 cooperate to form a claw-type structure; when the container cover 3 is installed on the container body 1, the elastic snap-fitting parts 8 are buckled on the inner side of the bottom of the outward-turned container edge 9 to achieve the sealing of the structure;

[0048] The annular limiting portion 2 is arranged on the outer side of the annular cover edge 5 to limit the deformation of the annular cover edge 5 to the outer shape. The annular limiting portion 2 is a closed-loop structure, and a brittle-break notch 6 is arranged on the annular limiting portion 2 for easy breaking. A pull handle 7 is arranged near the brittle-break notch 6 of the annular limiting portion 2. The closed loop of the annular limiting portion 2 is destroyed based on the breaking of the brittle-break notch 6, thereby releasing the restriction on the annular cover edge 5;

[0049] By providing structures such as the container body 1, the container cover 3 and the annular limiting portion 2, the sealing of the structure can be achieved based on the cooperation between the elastic clamping portion 8 and the outward-turned container edge 9. At the same time, the design of the annular limiting portion 2 can play a reinforcing effect, preventing the elastic clamping portion 8 from being separated from the outward-turned container edge 9, thereby improving the firmness of the structure; in addition, due to the provision of structures such as the brittle-break notch 6, the annular limiting portion 2 can be destroyed by destroying the brittle-break notch 6 during disassembly, thereby releasing the deformation restriction on the annular cover edge 5, so that force is applied to deform the annular cover edge 5, so that the elastic clamping portion 8 is separated from the outward-turned container edge 9, so as to complete the disassembly;

[0054] By providing the reinforcing ribs 10, the structural strength can be improved, and the loosening of the structure caused by the inward deformation of the edge 9 of the outward-turning container can be avoided, thereby improving the reliability.

[0055] In addition, by adding a number of reinforcing ribs 10 of corresponding thickness or distributing them in a circle at the outward-turned container edge 9 where the container body 1 and the container cover 3 are closed, after the container cover 3 is closed with the container body 1, the elastic snap-fitting portion 8 and the outward-turned container edge 9 can have sufficient support and snap-fitting strength, making the two difficult to separate, thereby further improving the tightness of the closing.

[0056] The container structure, the container body 1 and the container cover 3 can be compatible cup-type, bucket-type, bowl-type, box-type structures, and the overall shape can be circular, oval, square, rectangular or other polygonal structures in a top view; the container cover 3 can be an upwardly protruding or downwardly concave structure, as well as other shapes, etc., which will not be described in detail here;
