Description

Technical Field

[0001] This application relates to the field of rapeseed oil processing technology, and in particular to a deep freshness-locking system for rapeseed oil. Background Technology

[0002] To preserve the freshness of rapeseed oil, the storage containers need to be filled with nitrogen to reduce the oxygen content inside and lower the probability of the oil spoiling due to oxygen exposure. Traditional storage containers consist of a container body and a lid, with a simple structure. After nitrogen filling, it is easy for outside air to re-enter the container. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a deep freshness-locking system for rapeseed oil in order to prevent outside air from entering the interior of the nitrogen-filled tank.

[0004] The technical solution of this application is as follows:

[0005] This application provides a deep freshness-locking system for rapeseed oil, including a tank and a lid. A plug is rotatably connected to the lid and inserted into the opening of the tank. An air inlet pipe and an air outlet pipe are snapped onto the periphery of the plug. The lower ends of the air inlet pipe and the air outlet pipe are inserted into air holes on the end face of the tank opening. Rotation of the lid can push the plug into the inside of the tank opening to seal the air holes.

[0006] Using the technical solution of this application, after nitrogen is filled into the tank through the air inlet pipe, the screwing in of the cover will push the plug further into the tank opening until the plug seals the air hole, thus preventing outside air from entering the nitrogen-filled tank.

[0007] In some implementations, the plug has a connecting post that inserts into the cover.

[0008] In some implementations, the connecting column and the cover are arranged coaxially.

[0009] In some implementations, a positioning ring is screwed onto the connecting post.

[0010] In some implementations, the circumferential surface of the connecting column is provided with a slot.

[0011] In some implementations, the extension direction of the slot is parallel to the axis of the connecting post.

[0012] In some implementations, the vents are arranged parallel to the axis of the tank.

[0013] In some implementations, pores form ports on the inner wall of the can opening.

[0014] In some implementations, the axis of the port is arranged radially along the opening of the tank.

[0015] In some implementations, the pores are evenly distributed circumferentially along the can opening. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0028] In related technologies, to deeply preserve the freshness of rapeseed oil, the preservation container needs to be nitrogen-filled to reduce the oxygen content inside and lower the probability of the rapeseed oil spoiling due to contact with oxygen. Traditional preservation containers consist of a container body and a lid, with a simple structure, making it easy for outside air to re-enter the container after nitrogen filling.

[0029] In view of this, the purpose of this embodiment is to provide a deep freshness-locking system for rapeseed oil in order to prevent outside air from entering the interior of the nitrogen-filled tank.

[0030] Please see Figures 1-4In this embodiment, a rapeseed oil deep freshness-locking system includes a tank 10, a cover 20, and a plug 30. The plug 30 is rotatably connected to the cover 20 and is inserted into the tank opening 11 of the tank 10. An air inlet pipe 40 and an exhaust pipe 50 are snapped onto the circumferential surface of the plug 30. The lower ends of the air inlet pipe 40 and the exhaust pipe 50 are inserted into the air hole 12 on the end face of the tank opening 11. The rotation of the cover 20 can push the plug 30 into the tank opening 11 to seal the air hole 12.

[0031] Using the technical solution of this embodiment, after nitrogen is filled into the tank 10 through the air inlet pipe 40, the screwing of the cover 20 will push the plug 30 further into the tank opening 11 until the plug 30 seals the air hole 12, thus preventing outside air from entering the nitrogen-filled tank.

[0032] It should be noted that, compared with traditional food storage containers, this embodiment adds a plug 30 as a built-in sealing mechanism. The plug 30 is inserted into the can opening 11 at the top of the container 10. The outer wall of the plug 30 fits against the inner wall of the can opening 11 to form a sealed connection. Furthermore, the plug 30 can move up and down inside the can opening 11 under the action of external force, and maintains a sealed connection during the movement.

[0033] In this embodiment, a cylindrical connecting post 31 is integrally formed on the top surface of the plug 30. The connecting post 31 and the plug 30 are arranged coaxially, and are also arranged coaxially with the cover 20. The connecting post 31 is inserted into the through hole at the axis of the cover 20, so that the plug 30 and the cover 20 can rotate relative to each other. Two positioning rings 32 are screwed on the connecting post 31. The two positioning rings 32 are located on the upper and lower sides of the cover 20, respectively, so that the connecting post 31 is rotatably connected to the cover 20. Furthermore, two slots 33 are formed on the outer wall of the connecting post 31. The extending direction of the slots 33 is parallel to the axis of the connecting post 31. An air inlet pipe 40 is engaged in one slot 33, and an exhaust pipe 50 is engaged in the other slot 33.

[0034] In addition, two air holes 12 are provided on the upper surface of the can opening 11 of the can body 10. The two air holes 12 are evenly distributed around the circumference of the can opening 11. The air holes 12 are arranged parallel to the axis of the can body 10. The air holes 12 form ports 13 on the inner wall of the can opening 11, and the axis of the ports 13 is arranged radially along the can opening 11. The lower end of the air inlet pipe 40 is inserted into one of the air holes 12, and the lower end of the exhaust pipe 50 is inserted into the other air hole 12. The air inlet pipe 40 and the exhaust pipe 50 connect the inner cavity of the can body 10 to the outside.

[0035] In use, first screw the cap 20 a certain distance into the can opening 11 to ensure that the lower ends of the air inlet pipe 40 and the exhaust pipe 50 are inserted into the corresponding air holes 12, and the plug 30 is inserted into the can opening 11 and located above the port 13; then, nitrogen is filled into the can 10 through the air inlet pipe 40, and the gas inside the can 10 is discharged through the exhaust pipe 50. After the air is completely discharged, while continuing to fill with nitrogen, screw the cap 20 rectangularly into the can opening 11. At this time, the plug 30 is further pushed into the can opening 11 until the plug 30 moves below the port 13. At this time, the port 13 is blocked and sealed by the plug 30, and the air inlet pipe 40 and the exhaust pipe 50 are also in a closed state, and the nitrogen filling stops.

[0036] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
