Description

Technical Field

[0001] This utility model relates to the field of packaging container manufacturing technology, and in particular to a rotary easy-open lid and packaging can. Background Technology

[0002] The aluminum can was invented in the United States in 1963. It inherited the design features of previous cans, but incorporated a pull tab on the top of the lid. This revolutionized opening methods, bringing great convenience and enjoyment, and quickly gained widespread adoption. By 1980, the European and American markets had almost entirely adopted this type of aluminum can for packaging beer and carbonated beverages. However, opening this aluminum can required manually pulling the pull tab to tear open a portion of the lid to create an opening before the can could be opened to pour out the contents. Furthermore, the lid could not be resealed after opening, and if the contents were not used up at once, they would be exposed to the air and susceptible to damage from environmental contamination.

[0003] To achieve secondary sealing, a Chinese utility model patent with patent number ZL202320830609.6 and titled "An Aluminum-Plastic Composite Cover" was published on March 4, 2025. It includes an aluminum cover ring and a circular plastic cover plate. The circular plastic cover plate has a downward-extending side edge with an inwardly protruding connecting portion at its lower end. One side of the aluminum cover ring has a winding portion that rolls and seals with the can opening, and the other side has a flipping portion that clamps the connecting portion. The upper part of the circular plastic cover plate has at least one flipable cover body. Each flipable cover body has a mating structure with the upper part of the circular plastic cover plate that allows them to open or engage with each other. The upper part of the circular plastic cover plate has an opening corresponding to the flipable cover body. When the flipable cover body engages with the upper part of the circular plastic cover plate, it covers the opening. When the flipable cover body is opened, the opening communicates with the outside. This invention can be rolled and sealed with the opening of an aluminum can, and the cap is easy to open and close, allowing for repeated sealing. However, due to sealing issues, this composite cap is more suitable for packaging solid materials such as granules, and not suitable for packaging liquids, thus limiting its application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rotary easy-open cap, which, when used with a can body, makes it easy to switch between opening and sealing the can body, and has good sealing performance when sealing twice. It can also be used for packaging liquid materials and has a wide range of applications.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a rotary easy-open cap, comprising a cap body, a sealing body, and a handle. The cap body has an opening through hole in the middle. The sealing body includes a connecting part, an elastic part, and a sealing part. The sealing part is connected to the connecting part through the elastic part. The connecting part is fixed to the lower end face of the cap body. The sealing body corresponds to the opening through hole. One end of the handle has a toggle part, and the other end has a locking part. The middle part of the handle is rotatably connected to the middle position of the sealing part. The toggle part of the handle is always above the upper end face of the cap body. The sealing part has a ring of soft sealing protrusions. When the handle is rotated so that the locking part is locked on the upper end face of the cap body, the soft sealing protrusions fit against the lower end face of the cap body around the opening through hole to seal the opening through hole. When the handle is rotated so that the locking part is inserted into the opening through hole, the elastic part drives the sealing part away from the cap body to open the opening through hole.

[0006] Further improvements include the addition of multiple flow channel holes spaced apart along the location of the flexible sealing protrusions in the sealing part. These flexible sealing protrusions are made of silicone material, and a ring of flexible sealing protrusions is formed on both the upper and lower end faces of the sealing part. These flexible sealing protrusions on the upper and lower end faces are connected as a single unit through the multiple flow channel holes. This ensures a more secure bond between the flexible sealing protrusions and the sealing part, guaranteeing better sealing performance of the easy-open rotary cover.

[0007] In a further improvement, the middle position of the sealing part protrudes upward to form a hinge part, and the middle position of the handle is provided with a hinge hole. The handle is sleeved on the hinge part through the hinge hole to form a rotatable connection.

[0008] Preferably, the connecting part of the sealing body is fixedly connected to the lower end face of the cover body by riveting. This facilitates manufacturing.

[0009] Preferably, the cover body is made of metal, and the sealing body and the handle are also made of metal. More preferably, the metal material is aluminum alloy.

[0010] In a further improvement, the sealing body is provided with two elastic parts, which are located on opposite sides of the connecting part and the sealing part, respectively. The connecting part is connected to the sealing part through the two elastic parts. In this way, the two elastic parts can ensure reliable movement and return of the sealing body, so that the easy-open cover can be reliably opened and resealed.

[0011] Furthermore, the connecting portion has a limiting protrusion on the side near the sealing portion, and the sealing portion has an overlapping protrusion on the side near the connecting portion, with the overlapping protrusion resting against the upper end face of the limiting protrusion. This ensures that a ring of soft sealing protrusions can reliably fit against the lower end face of the cover body around the opening to better seal the opening.

[0012] Preferably, the elastic part is formed by bending the plate multiple times.

[0013] Preferably, the connecting part is connected to the sealing part through two elastic parts to form an integral structure.

[0014] This rotary easy-open cap, when the rotating handle is turned so that the locking part is engaged with the upper end face of the cap body, the soft sealing protrusion adheres to the lower end face of the cap body around the opening, thus sealing the opening. Turning the rotating handle again causes the locking part to enter the opening, and the elastic part drives the sealing part away from the cap body, opening the opening. When used with a can, it facilitates easy switching between opening and sealing. Furthermore, because the soft sealing protrusion adheres to the lower end face of the cap body around the opening, it provides good sealing performance during primary or secondary sealing, and is also suitable for packaging liquid materials, thus having a wide range of applications.

[0015] This utility model also discloses a packaging can, including a can body, which includes the above-mentioned rotating easy-open lid. The outer periphery of the lid body of the rotating easy-open lid is provided with a winding part, and the edge of the can body opening is fixedly connected to the winding part by winding and sealing.

[0016] The packaging can of this utility model adopts the above-mentioned rotary easy-open lid, which makes it convenient to switch between opening and sealing the can body, has good sealing performance when sealing twice, can package a wide range of materials, and has a wide range of applications.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Figures 1 to 9 As shown, a rotary easy-open lid includes a lid body 1, a sealing body 2, and a handle 3. The lid body 1 has an opening through hole 11 in the middle. The sealing body 2 includes a connecting part 21, an elastic part 22, and a sealing part 23. The sealing part 23 is connected to the connecting part 21 through the elastic part 22. Specifically, the sealing body 2 has two elastic parts 22, which are located on opposite sides of the connecting part 21 and the sealing part 23, respectively. The connecting part 21 is connected to the sealing part 23 through the two elastic parts 22, and the connecting part 21 is connected to the sealing part 23 through the two elastic parts 22 to form an integral structure. The elastic part 22 is formed by bending a plate multiple times.

[0032] The connecting part 21 is fixed to the lower end face of the cover body 1. The sealing body 2 corresponds to the opening through hole 11. One end of the handle 3 is provided with a toggle part 31 and the other end is provided with a locking part 32. The middle part of the handle 3 is rotatably connected to the middle position of the sealing part 23. The toggle part 31 of the handle 3 is always above the upper end face of the cover body 1. The sealing part 23 is provided with a ring of soft sealing protrusions 24. When the handle 3 is rotated so that the locking part 32 is locked on the upper end face of the cover body 1, the soft sealing protrusions 24 fit against the lower end face of the cover body 1 around the opening through hole 11 to seal the opening through hole 11. When the handle 3 is rotated so that the locking part 32 falls into the opening through hole 11, the elastic part 22 drives the sealing part 23 away from the cover body 1 to open the opening through hole 11.

[0033] The sealing part 23 has multiple flow channel holes 231 spaced apart along the positions where the flexible sealing protrusions 24 are provided. The flexible sealing protrusions 24 are made of silicone material. A ring of flexible sealing protrusions 24 is formed on both the upper and lower end faces of the sealing part 23. The flexible sealing protrusions 24 on the upper and lower end faces of the sealing part 23 are connected as one unit through the multiple flow channel holes 231. This allows the flexible sealing protrusions 24 to be more firmly bonded to the sealing part 23, ensuring that the entire easy-open cover has good sealing performance.

[0034] The connecting portion 21 has a limiting protrusion 211 on the side near the sealing portion 23, and the sealing portion 23 has an overlapping protrusion 232 on the side near the connecting portion 21. The overlapping protrusion 232 rests against the upper end face of the limiting protrusion 211. This ensures that a ring of soft sealing protrusions 24 can reliably fit against the lower end face of the cover body 1 around the opening through hole 11 to better seal the opening through hole 11.

[0035] The sealing part 23 protrudes upward at the middle position to form a hinge part 233, and the handle 3 is provided with a hinge hole 33 at the middle position. The handle 3 is sleeved on the hinge part 233 through the hinge hole 33 to form a rotatable connection.

[0036] The connecting part 21 of the sealing body 2 is fixedly connected to the lower end face of the cover body 1 by riveting. Specifically, the connecting part 21 is fixedly connected to the lower end face of the cover body 1 through two riveting points 212.

[0037] The cover body 1 is made of metal, as are the sealing body 2 and the handle 3. The preferred metal material is aluminum alloy.

[0038] Figures 10 to 12 As shown, a packaging can includes a can body 10 and the aforementioned rotary easy-open lid. The outer periphery of the lid body 1 of the rotary easy-open lid is provided with a winding portion 12, and the edge of the opening of the can body 10 is fixedly connected to the winding portion 12 by winding and sealing. At this time, rotating the handle 3 causes the locking portion 32 to fall into the opening through hole 11, and the elastic portion 22 drives the sealing portion 23 away from the lid body 1 to open the opening through hole 11, and the packaging can is in the open state.

[0039] Combination Figure 8 , Figure 9 , Figure 13 As shown, when the handle 3 is rotated so that the snap-fit ​​part 32 is snapped onto the upper end face of the cover body 1, the soft sealing protrusion 24 can seal the opening through hole 11 by fitting against the lower end face of the cover body 1 around the opening through hole 11, and the can body 10 is in a sealed state.

[0040] Therefore, this utility model allows for easy switching between the open and sealed states of the tank 10 by rotating the rotary handle 3, reliably achieving sealing or secondary sealing.

[0041] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
