Detailed Implementation

[0034] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0035] like Figures 1 to 10 As shown, a lid adapted to different food packaging containers includes a lid body 1, the lid body 1 is provided with at least one connecting end 2 connected to the food packaging container, the connecting end 2 is provided with at least one connecting structure, and the lid body 1 is detachably connected to the food packaging container through the connecting structure.

[0036] In this utility model, since the main body 1 of the cover is provided with at least one connecting end 2, and each connecting end 2 is equipped with at least one connecting structure, it can adapt to food packaging containers of different specifications or different connection methods through different connecting structures, eliminating the need to equip different containers with separate cover, reducing the cost of use for consumers and the production cost for producers; at the same time, the design of at least one connecting end 2 supports the simultaneous connection of two or more food packaging containers, meeting the needs of carrying multiple foods at the same time, improving the convenience of use, and meeting the needs for a universally adaptable cover that can connect multiple containers.

[0037] The food packaging container in this utility model is a container for holding solid food and / or liquid food. Preferably, it is a can body 10 for eight-treasure porridge, a can body 11 for easy-open can, a PET plastic bottle 12 with a cap diameter of 28 mm, or a PET plastic bottle 13 with a cap diameter greater than 28 mm, all manufactured according to national standards.

[0038] Furthermore, at least two connection structures are provided on the same connection end 2 to connect to a food packaging container. In this way, by setting multiple connection structures on the same connection end 2, the lid body 1 can be adapted to different food packaging containers, or different connection structures can be adapted to different connection parts on the same food packaging container. This broadens the adaptability of the lid to food packaging containers of different specifications and connection methods, reduces the need for dedicated lids, lowers usage and production costs, and enhances the versatility and practicality of the lid.

[0039] Furthermore, the limiting component is arranged parallel to the end face of the lid body 1, or the limiting component is arranged at an angle, forming a thread within the connecting end 2. When the limiting component is parallel to the end face of the lid body 1, the container's protruding edge 9 can be directly engaged with the limiting component, preventing the food packaging container from tilting. When the limiting component is arranged at an angle, forming a thread within the connecting end 2, it not only achieves the effect of engaging with the lid body 1 but can also be directly connected to the threaded lid body 1.

[0040] In the first embodiment of this utility model, the connecting structure is a limiting component, which is arranged circumferentially along the connecting end 2 and is locked to the container protrusion 9 on the food packaging container.

[0041] In detail, in this embodiment, the connecting structure is a limiting component. The limiting component is connected to the container protrusion 9 on the food packaging container, which can achieve the structural characteristics of the container connection part, enhance the stability of the connection between the lid and the container, and also quickly realize the detachable connection between the lid and the container.

[0042] The limiting component is one or more of a limiting protrusion, a limiting segment, and / or a limiting protrusion.

[0043] In this embodiment, when the limiting component is a limiting protrusion, it is an integrally formed circular protrusion arranged along the circumference of the connecting end 2. When the limiting component is a limiting segment, there are gaps between multiple limiting segments. When the limiting segment engages with the container protrusion 9, a ventilation channel can be formed through the gaps to allow air to escape from the inside of the lid body 1, improving the ease of connection and saving production materials and reducing production costs. When the limiting component consists of multiple limiting protrusions forming a line or line segment, the multiple limiting protrusions forming a limiting protrusion or limiting segment not only achieve the effect of a limiting protrusion or limiting segment but also further reduce production costs.

[0044] Furthermore, at least two limiting components are provided on the same connecting end 2. These at least two limiting components are coaxially arranged along the axial direction of the cover body 1, and their size gradually decreases from the outside to the inside along the axial direction of the cover body 1. In this way, food packaging containers of different diameters can be adapted by using convex edges of different radii, achieving cross-specification compatibility without the need for additional changes to the connecting structure.

[0045] The food packaging container has a container protrusion 9 on its upper and / or lower parts, which can be used to connect the upper or lower parts of the food packaging container, thus achieving upright or inverted connection of the food packaging container.

[0046] In a second embodiment of this utility model, the connecting structure is a recessed portion that is recessed inward on the cap body 1. The recessed portion is adapted to the bottle cap 8 provided with the food packaging container, and the bottle cap 8 is snapped into the recessed portion. In this way, the connection effect between the cap body 1 and the food packaging container can be guaranteed, and the connection stability can be guaranteed by the snapping method. Moreover, the connection effect can be achieved without other complex connecting parts, and it can also be compatible with more food packaging containers of different specifications with standard bottle caps 8.

[0047] In this embodiment, the recessed portion can be located within the cap body 1, and its sidewall can be a curved surface adapted to the sidewall of the bottle cap 8, or it can be multiple inner wall ribs 15 extending towards the center, with the ends of the multiple inner wall ribs 15 collectively clamping the bottle cap 8. Furthermore, each inner wall rib 15 is an elastic telescopic member, so that bottle caps 8 of different radii can be adapted through the elastic telescopic effect of the inner wall ribs 15.

[0048] Furthermore, at least two recesses are provided on the cap body 1, and the at least two recesses are coaxially arranged along the axial direction of the cap body 1, with the radius of the at least two recesses gradually decreasing from the outside to the inside along the axial direction of the cap body 1. In this way, the cap body 1 can be adapted to connect with food packaging containers with bottle caps 8 of different sizes through the recesses of different radii.

[0049] In this embodiment, the two recesses can also be staggered. When two food packaging containers equipped with bottle caps 8 are connected simultaneously through the two recesses, a "Z"-shaped connection can be formed when the two food packaging containers are connected. This not only changes the appearance and suits the tastes of some people, but also shortens the overall length after connection.

[0050] As a third embodiment of this implementation, the connection structure is an inclined platform 5 that is set on the main body 1 of the cover, tilted inward and with a radius that gradually decreases from the outside to the inside. The inclined platform 5 abuts against the top surface of the bottle cap 8 provided with the food packaging container. In this way, based on different positions of the inclined platform 5, it can be adapted to bottle caps 8 with different radii, thus adapting to the connection of different food packaging containers.

[0051] In some embodiments of this utility model, the lid is provided with two or more connecting ends 2 to simultaneously connect two or more food packaging containers. For example, the lid body 1 is provided with two oppositely arranged connecting ends 2, so that after connecting two food packaging containers, the overall shape is straight or "Z"-shaped; or the two connecting ends 2 are not arranged in a straight line, so that after connecting two food packaging containers, a certain angle is formed between the two food packaging containers, similar to a bending effect. If six connecting ends 2 are provided on the lid body 1, the positions of the six connecting ends 2 are like the six faces of a die. Similarly, since this utility model can adapt to the connection of different food packaging containers, it can add fun to the connection process.

[0052] In some embodiments of this utility model, the main body 1 of the cover is cylindrical, square, or hourglass-shaped, which can be adapted to different usage scenarios and holding habits, and consumers can choose to use it according to their needs or preferences.

[0053] In some embodiments of this utility model, at least two connecting ends 2 are connected together, allowing two food packaging containers to be connected through opposite ends of the same connecting structure. Furthermore, the two connecting ends 2 are located at opposite ends of the cover body 1.

[0054] The following are several embodiments to clearly illustrate this utility model.

[0055] Example 1

[0056] When the food packaging container is a two-piece or three-piece can, a container protrusion 9 is provided on the can body; the limiting component is one or more of a limiting protrusion, a limiting segment, or a limiting protrusion. In this embodiment, the limiting protrusion is used as an example for explanation.

[0057] Example 1-1

[0058] Example 1-1 is a further specific embodiment of Example 1. The connecting structure includes at least one limiting protrusion adapted to the container protrusion 9, and the limiting protrusion and the container protrusion 9 are interlocked. It should be noted that in existing food packaging containers, the container protrusion 9 can be located at the upper or lower part of the can body. The connecting structure in this utility model can be interlocked with the container protrusion 9 through the limiting protrusion. Preferably, the container protrusion 9 is located at the upper part of the can body, which can ensure that the food packaging container is upright.

[0059] In detail, when the food packaging container is a can body commonly known as a two-piece can, such as an easy-open can for storing cola or beer, or a can body commonly known as a three-piece can, such as an eight-treasure porridge can for storing eight-treasure porridge, the upper part of the can body is provided with a container protrusion 9, and the connecting structure includes at least one limiting protrusion. When this utility model is connected to the container protrusion 9 through the limiting protrusion, the limiting protrusion and the container protrusion 9 are interlocked.

[0060] Examples 1-2

[0061] like Figure 7 As shown, Examples 1-2 are further specific embodiments of Example 1. The connecting structure includes two or more limiting protrusions, which are arranged along the height direction of the cover body 1, and the diameter of the two or more limiting protrusions gradually decreases along the direction from the connecting part into the cover body 1.

[0062] Since the lid body 1 has two or more limiting protrusions, namely the first limiting protrusion 3 and the second limiting protrusion 4, and the diameter of the container protrusion 9 corresponding to the cans of different diameters is different, the two or more protrusions can be connected to cans of different diameters. This allows the same lid body 1 to be used to adapt to two different diameter container protrusions 9, thereby enabling the connection of two different diameter cans.

[0063] The following are the national standard dimensions for some common can sizes. For example, a 355 ml can has a diameter of 67.7 mm and a height of 124.7 mm; a 310 ml can has a diameter of 53.6 mm and a height of 120 mm; and a 500 ml can has a diameter of 66 mm and a height of 167 mm.

[0064] For example, there are two limiting protrusions, the first limiting protrusion 3 and the second limiting protrusion 4, on the lid body 1. The first limiting protrusion 3 and the second limiting protrusion 4 can respectively adapt to a 355 ml can and a 310 ml can, so that the same lid body 1 can be used to adapt to the protrusions 9 of two containers with different diameters, thereby realizing the connection of two cans with different diameters.

[0065] Alternatively, the first limiting protrusion 3 and the second limiting protrusion 4 on the lid body 1 can be adapted to the can body 10 for loading cola and other beverage cans and eight-treasure porridge cans, respectively. Since the diameter of the eight-treasure porridge can body 10 is larger than the diameter of the beverage can body 11, the first limiting protrusion 3 can be connected to the container protrusion 9 of the eight-treasure porridge can body 10, or the second limiting protrusion 4 can be connected to the container protrusion 9 of the beverage can body 11. This allows the use of the same lid body 1 to adapt to two different diameter container protrusions 9, thereby enabling the connection of two cans with different diameters.

[0066] Example 2

[0067] The food packaging container is a bottle body, and the bottle body is equipped with a bottle cap 8; at least one inwardly recessed part is provided in the middle of the connecting part, and the shape and size of the recessed part are adapted to the shape and size of the bottle cap 8, and the bottle cap 8 is locked in the recessed part.

[0068] Example 2-1

[0069] Example 2-1 is a further specific embodiment of Example 2. When the food packaging container is a can commonly known as a three-piece can for holding eight-treasure porridge, the lid of the can has a square protrusion, and the recess on the main body of the box is a square recess. Since the shape and size of the protrusion match the shape and size of the recess, the protrusion can be engaged in the recess. Furthermore, if the food packaging container, a three-piece can commonly known as a three-piece can for holding eight-treasure porridge, does not have a lid, the container protrusion 9 of the can can also be adapted and connected to the recess on the main body of the box, achieving the same effect.

[0070] Example 2-2

[0071] Example 2-2 is a further specific embodiment of Example 2. When the food packaging container is a PET plastic bottle for loading mineral water, tea, etc., the PET plastic bottle is equipped with a round bottle cap 8. The recess on the main body 1 of the cap is a round recess. Since the shape and size of the bottle cap 8 are adapted to the shape and size of the recess, the bottle cap 8 can be locked in the recess.

[0072] Example 2-3

[0073] Examples 2-3 are further specific embodiments of Example 2. Multiple inner wall ribs 15 extending towards the center are provided along the circumferential direction of the side wall of the connecting end 2. The ends of the multiple inner wall ribs together clamp the bottle cap 8.

[0074] Examples 2-4

[0075] like Figure 8As shown, Examples 2-4 are preferred embodiments of Examples 2-3. Each inner wall rib 15 is an elastic expansion member, and multiple inner wall ribs are arranged in parallel. The elastic expansion effect of the inner wall ribs 15 can be used to adapt to bottle caps 8 of different radii.

[0076] Examples 2-5

[0077] Examples 2-5 are further specific embodiments of Example 2, wherein an inwardly inclined ramp 5 is provided inside the cap body 1, and the radius gradually decreases from the outside to the inside. Under the action of the ramp 5, the ramp 5 abuts against the upper edge of the cap 8, thereby achieving the effect of the cap body 1 and the food packaging container. Furthermore, the ramp 5 can also abut against the container's protruding edge 9, thereby achieving the effect of the cap body 1 and the food packaging container. It should be noted that in this embodiment, the effect of the cap body 1 and the food packaging container is achieved by relying on the two opposing ramps 5 or the ramp 5 clamping the container's protruding edge 9 or the cap with the inner wall surface of the cap body 1.

[0078] Examples 2-6

[0079] like Figure 3 As shown, Examples 2-6 are further specific embodiments of Example 2. A limiting elastic member 14 for clamping the bottle cap 8 is provided inside the recess. The limiting elastic member 14 is bent and attached to the inner wall of the recess, and the convex surface of the limiting elastic member 14 protrudes to the center. When the bottle cap 8 or the protrusion is clamped into the recess, the slight deformation of the convex surface of the limiting elastic member 14 can improve the ease of clamping into the recess, and after clamping, it can improve the stability of the connection between the recess and the bottle cap 8 or the protrusion.

[0080] The limiting elastic element 14 can be fixedly installed on the inner wall of the recess by welding or hot-melt connection, so as to connect the bottle cap 8 or the can cap.

[0081] Examples 2-7

[0082] like Figure 9 As shown, Examples 2-7 are further specific embodiments of Example 2. The connecting structure includes two or more recesses. The two or more recesses are arranged along the height direction of the cover body 1, and the diameter of the two or more recesses gradually decreases along the direction from the connecting part to the inside of the cover body 1.

[0083] Since there are two or more recesses on the cap body 1, and the size and shape of the bottle cap 8 or can cap corresponding to different bottles or cans are different, the shape and size of the recesses can be set accordingly along the direction from the fixing part to the inside of the cap body 1, and the diameter of the two or more recesses gradually decreases along the direction from the connecting part to the inside of the cap body 1.

[0084] In detail, two concentric recesses can be provided on the cap body 1. The two recesses are the first recess 6 and the second recess 7. The two recesses are different in size and can be the same or different in shape, so that the protrusions or caps 8 on different bottles or cans can be inserted into the recesses, so that the same cap body 1 can be used to adapt to two different cap bodies 1.

[0085] For example, two concentric recesses are provided on the main body 1 of the lid. The first recess 6 is a square recess, and the second recess 7 is a circular recess. The two recesses are respectively adapted to the protrusions on the bottle caps 8 of PET plastic bottles used for holding mineral water, tea, etc., and the lids of eight-treasure porridge cans. The PET plastic bottles or eight-treasure porridge cans can be inserted into the recesses respectively, so that the same lid body 1 can be used to adapt to two different lid bodies 1.

[0086] Alternatively, the diameter of the existing PET plastic bottle cap 8 is 28 mm. The first recess 6 can be adapted to PET plastic bottles 12 with a cap diameter of 28 mm, and the second recess 7 can be adapted to PET plastic bottles 13 with a cap diameter greater than 28 mm, so as to achieve the effect of using the same cap body 1 to adapt to two different cap bodies 1.

[0087] Examples 2-8

[0088] like Figure 10 As shown, the two connecting ends 2 are internally connected, and the two coaxial recesses have different radii. In this way, two bottles with caps 8 of different radii can be connected through the two recesses with different radii. After the bottle with the larger cap 8 is separated from the cap body 1, the bottle with the larger cap 8 can be replaced with a bottle with a smaller cap 8 whose radius is compatible. The caps 8 of the two bottles share a recess.

[0089] Example 3

[0090] The connecting structure of this utility model includes a recessed part and a limiting protrusion. The positions of the recessed part and the limiting protrusion are as in Embodiment 1 and Embodiment 2. In this way, this utility model can achieve the effect of using the same cap body 1 to adapt to two different cap bodies 1: a bottle body equipped with a cap 8 and a can body equipped with a container protrusion 9.

[0091] Example 4

[0092] The connecting structure of this utility model includes two recessed portions and two limiting protrusions. The positions of the recessed portions and limiting protrusions are as described in Embodiments 1 and 2. Thus, this utility model allows the use of a single cap body 1 to accommodate four different cap bodies 1. In use, it can accommodate two different cap bodies 1: one for a bottle with a cap 8 and the other for a can with a container protrusion 9; it can accommodate two cap bodies 1 for bottles with caps 8; or it can accommodate two cap bodies 1 for cans with container protrusions 9.

[0093] Example 5

[0094] Two connecting ends 2 are located at opposite ends of the cap body 1. Both connecting ends 2 can be connected to the limiting protrusion via the container protrusion 9, or to the bottle cap 8 via a recess, thus achieving a connection with the food packaging container. In this way, two food packaging containers can be connected using a single cap body 1.

[0095] Furthermore, in Embodiments 1 to 5, the connecting part is also provided with a receiving protrusion for placing eating utensils (not shown in the figure, similar to the protrusion for placing a spoon in an eight-treasure porridge can), and the receiving protrusion is provided at least one connecting structure near the food packaging container.

[0096] In detail, the accommodating protrusion provides independent placement for eating utensils such as forks, spoons, and chopsticks, offering users matching tools when using food packaging containers and / or storage spaces. Furthermore, arranging the accommodating protrusion above the connecting structure makes full use of the space above the connecting structure and does not affect the connection between the lid body 1 and the food packaging container via the connecting structure. When the food packaging container is a bottle with a cap 8, eating utensils may not be required to ensure the effective connection between the cap and the food packaging container.

[0097] It should be noted that the receiving protrusion can be a receiving protrusion edge provided along the circumference of the connecting part, or it can be multiple intermittently provided protrusions provided along the circumference of the connecting part, providing users with a matching tool for using food in food packaging containers and / or storage spaces.

[0098] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
