Technical Field

[0001] The present application relates to the field of packaging containers, and in particular to a sealed material cylinder for aseptic filling. Background Art

[0002] Mixers are widely used in pharmaceutical, chemical, food and other fields to mix different materials evenly. Currently, most mixers on the market use open barrels. Although this design can meet basic mixing needs, it cannot maintain sterility during the mixing and filling process, posing a risk of contamination.

[0003] In the prior art, after the mixing is completed, the material inside the barrel is usually sterilized additionally to make up for the inability of the open barrel to maintain sterility. However, performing additional sterilization on the material inside the barrel will reduce production efficiency. Utility Model Content

[0004] In order to improve production efficiency, the present application provides a closed barrel for aseptic filling.

[0005] The present application provides a sealed barrel for aseptic filling, which adopts the following technical solution:

[0006] A closed material barrel for aseptic filling comprises a material barrel body, a support ring is fixedly mounted on the material barrel body, a first sealing ring is mounted on the material barrel body, a cover plate is disposed on the top end of the material barrel body, the first sealing ring is located between the support ring and the cover plate, a locking assembly is installed between the cover plate and the support ring, the locking assembly is used to drive the cover plate to press the first sealing ring against the support ring, a feeding assembly is installed on the top side of the cover plate, and the feeding assembly is used to add material to the inside of the material barrel body.

[0007] By adopting the above technical solution, the cover plate covers the top of the barrel body and is sealed by the first sealing ring, thereby closing the barrel body. After the barrel body is closed, the material inside the barrel body is conducive to maintaining sterility during the mixing and filling process, thereby reducing the need for additional sterilization of the material inside the barrel body, thereby improving production efficiency.

[0008] Optionally, the locking assembly includes a first chuck, a second chuck, a first connecting block, a second connecting block and a bolt, the first chuck and the second chuck are both bent and arranged to tightly abut against the side of the support ring and the cover plate facing away from each other, the first connecting block is fixedly installed on the top side of the first chuck, the second connecting block is fixedly installed on the top side of the second chuck, the first connecting block is provided with a through hole for the bolt to pass through, and the second connecting block is provided with a screw hole for the bolt thread to pass through.

[0009] By adopting the above technical solution, the first chuck and the second chuck clamp the support ring and the cover plate, so that the support ring and the cover plate clamp the first sealing ring, thereby improving the airtightness of the barrel body. The bolt passes through the through hole and is screwed into the screw hole, which is conducive to fixing the first chuck and the second chuck, thereby reducing the occurrence of the first chuck and the second chuck falling from the cover plate.

[0010] Optionally, the top side of the support ring is lower than the top of the barrel body, and the top side of the first sealing ring is higher than the barrel body before being squeezed by the cover plate. A positioning block is fixedly installed on one side of the cover plate close to the barrel body, and the surrounding side of the positioning block is against the inner wall of the barrel body.

[0011] By adopting the above technical solution, the part of the barrel body that is higher than the support ring limits the first sealing ring, thereby reducing the slippage of the first sealing ring and improving the sealing performance of the barrel body. The positioning block enters the barrel body for positioning, so that the cover plate and the support plate are aligned and the first sealing ring is pressed.

[0012] Optionally, the feed assembly includes a feed connector, a sealing cap, a connecting cap and a feed pipe, the feed connector is fixedly mounted on the top side of the cover plate, the sealing cap and the connecting cap are both used to be threadedly sleeved on the feed connector, and one end of the feed pipe is fixedly connected to a side of the connecting cap away from the cover plate.

[0013] By adopting the above technical solution, when it is necessary to add material to the inside of the barrel body, the connection cap is screwed into the feed joint, and then the material is added to the barrel body from the feed pipe. After the material is added to the inside of the barrel body, the connection cap is removed from the feed joint, and the sealing cap is screwed into the feed joint, which is conducive to blocking the feed joint and reducing the occurrence of bacteria entering the inside of the barrel body from the feed joint.

[0014] Optionally, a second sealing ring is fixedly mounted on the inner top wall of the sealing cap and the inner top wall of the connecting cap, and the second sealing ring is used to tightly abut against an end of the feed connector away from the cover plate.

[0015] By adopting the above technical solution, after the connecting cap or the sealing cap is screwed into the feed joint, the second sealing ring performs sealing, thereby reducing the occurrence of bacteria entering the interior of the barrel body from the feed joint.

[0016] Optionally, a piston is provided inside the barrel body, and the circumference of the piston is in contact with the inner wall of the barrel body.

The end of the connecting rod away from the mounting block is fixedly connected to the limit plate, and the limit plate is in contact with the outer bottom wall of the barrel body.

[0017] By adopting the above technical solution, when adding material into the barrel body, the piston is placed into the inner bottom wall of the barrel, and then the connecting rod is screwed into the screw groove, so that the piston remains fixed inside the barrel body. When taking out the material inside the barrel body for filling, the connecting rod is screwed out of the screw groove, and then the piston is pushed from the push port to move, so as to facilitate the material inside the barrel body to be pushed out.

[0018] Optionally, the barrel body is provided with a jacket, which wraps the circumferential side and the bottom side of the barrel body.

[0019] By adopting the above technical solution, the outer jacket wraps around the circumference of the barrel body, so that it is convenient for the mixer to fix the barrel body and then perform mixing.

[0020] Optionally, a positioning rod is fixedly mounted on the outer bottom wall of the barrel body, and a positioning hole for the positioning rod to pass through is opened on the bottom side of the outer sleeve.

[0021] By adopting the above technical solution, the positioning rod is inserted into the positioning hole, thereby reducing the radial slippage of the barrel body inside the outer sleeve.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] Example 1.

[0037] The embodiment of the present application discloses a closed barrel for aseptic filling.

[0038] Reference Figure 1 , Figure 2 A sealed barrel for aseptic filling comprises a barrel body 1 and a cover plate 2, wherein the cover plate 2 is arranged on the top of the barrel body 1.

[0039] Reference Figure 3 , Figure 4 A positioning block 3 is fixedly mounted on one side of the cover plate 2 close to the barrel body 1. The positioning block 3 is arranged inside the barrel body 1, and the surrounding side of the positioning block 3 is in contact with the inner wall of the barrel body 1. The positioning block 3 and the inner wall of the barrel are mutually engaged, thereby reducing the cover plate 2 from sliding off the top of the barrel.

[0040] Reference Figure 3 , Figure 4 The barrel body 1 is sleeved with a support ring 22 and a first sealing ring 4, and the inner wall of the support ring 22 is fixedly connected to the outer wall of the barrel body 1. The first sealing ring 4 is located between the support ring 22 and the cover plate 2. The top side of the support ring 22 is lower than the top side of the barrel body 1, so as to facilitate the limiting of the first sealing ring 4. When the first sealing ring 4 is not squeezed by the cover plate 2, the top side of the first sealing ring 4 is higher than the top side of the barrel body 1. After the cover plate 2 squeezes the first sealing ring 4, the first sealing ring 4 is deformed to block the gap between the cover plate 2 and the barrel body 1.

[0041] Reference Figure 3 , Figure 4 A locking assembly 7 is provided between the cover plate 2 and the support ring 22, and the locking assembly 7 is used to drive the cover plate 2 to press the first sealing ring 4 against the support ring 22. The locking assembly 7 includes a first chuck 71, a second chuck 72, a first connecting block 73, a second connecting block 74 and a bolt 75.

[0042] The first chuck 71 and the second chuck 72 are both bent. After the first chuck 71 and the second chuck 72 are bent, the first chuck 71 and the second chuck 72 are both tightly pressed against the side of the support ring 22 and the cover plate 2 that are away from each other. The first chuck 71 and the second chuck 72 clamp the support ring 22 and the cover plate 2, so that it is convenient for the cover plate 2 to squeeze the first sealing ring 4, and the first sealing ring 4 is deformed to block the gap between the cover plate 2 and the barrel body 1. After the barrel body 1 is closed by the cover plate 2, the material inside the barrel body 1 is not easily contaminated by bacteria, thereby reducing the need for additional sterilization of the material inside the barrel body 1, thereby improving production efficiency.

[0043] Reference Figure 3 , Figure 4 The first connection block 73 is fixedly mounted on the top side of the first chuck 71, and the second connection block 74 is fixedly mounted on the top side of the second chuck 72. The first connection block 73 is provided with a through hole 9 for the bolt 75 to pass through, and the second connection block 74 is provided with a screw hole 8 for the bolt 75 to thread through. After the first chuck 71 and the second chuck 72 clamp the support ring 22 and the cover plate 2, the bolt 75 passes through the through hole 9 and then screws into the screw hole 8, thereby reducing the possibility of the first chuck 71 and the second chuck 72 falling off when the barrel body 1 is mixed.

[0044] Reference Figure 4 , Figure 5 A feed assembly 10 is provided on the top side of the cover plate 2, and the feed assembly 10 includes a feed connector 101, a sealing cap 102, a connecting cap 103 and a feed pipe 104. The feed connector 101 is fixedly mounted on the top side of the cover plate 2, the sealing cap 102 and the connecting cap 103 are both used for threading on the feed connector 101, and one end of the feed pipe 104 is fixedly connected to a side of the connecting cap 103 away from the cover plate 2.

[0045] When it is necessary to inject material into the barrel body 1, the connection cap 103 is screwed into the feed connector 101. Then the material is injected into the barrel body 1 from the feed pipe 104. The opening of the feed pipe 104 is smaller than that of the barrel body 1, which helps to reduce the possibility of bacterial contamination of the barrel body 1 during the feeding process.

[0046] After the material inside the barrel body 1 is added, the connecting cap 103 is screwed out from the feed connector 101 , and then the sealing cap 102 is screwed into the feed connector 101 , thereby facilitating sealing of the feed connector 101 and improving the sealing performance of the barrel body 1 .

[0047] In another embodiment, the feed assembly 10 only has a feed connector 101 and a sealing cap 102. The feed connector 101 is used to directly inject material into the barrel body 1.

[0048] Reference Figure 4 , Figure 5 The inner top wall of the sealing cap 102 and the inner top wall of the connecting cap 103 are both fixedly mounted with a second sealing ring 5. After the sealing cap 102 and the connecting cap 103 are screwed into the feed connector 101, the second sealing ring 5 is pressed against the end of the feed connector 101 away from the cover plate 2, thereby improving the sealing performance of the barrel body 1.

[0049] Reference Figure 3 , Figure 6 A piston 11 is arranged inside the barrel body 1, and the circumference of the piston 11 is pressed against the inner wall of the barrel body 1. The piston 11 is sleeved with a third sealing ring 6, and a ring groove 12 for the third sealing ring 6 to enter is provided on the circumference of the piston 11. The piston 11 is placed inside the barrel body 1, and the third sealing ring 6 is pressed against the inner wall of the barrel body 1. A push-out port 13 is provided on the bottom side of the barrel body 1.

[0050] When the material inside the barrel body 1 is poured out for filling, some material will remain inside the barrel body 1. At the same time, some materials have high viscosity, and it is difficult to take the materials out from the barrel body 1. The piston 11 is squeezed through the push port 13, and the piston 11 pushes the material inside the barrel body 1 out, thereby facilitating the removal of the material inside the barrel body 1 and reducing the residue.

[0051] Reference Figure 3 , Figure 6The bottom side of the piston 11 is embedded with a mounting block 14, and the bottom side of the barrel body 1 is provided with a connecting rod 15 and a limiting plate 16. The bottom side of the mounting block 14 is provided with a screw groove 17 for the connecting rod 15 to be threaded, and the end of the connecting rod 15 away from the mounting block 14 is fixedly connected to the limiting plate 16.

[0052] After the piston 11 is placed into the inner bottom wall of the barrel body 1, the connecting rod 15 is screwed into the screw groove 17, so that the limit plate 16 is pressed against the outer bottom wall of the barrel body 1, thereby facilitating the fixing of the piston 11 and reducing the movement of the piston 11 when the barrel body 1 is placed in the mixer for mixing.

[0053] Reference Figure 3 , Figure 7 The barrel body 1 is provided with a jacket 18, which covers the circumference and bottom of the barrel body 1. A positioning rod 19 is fixedly mounted on the outer bottom wall of the barrel body 1, and a positioning hole 20 for the positioning rod 19 to pass through is provided on the bottom side of the jacket 18. A clearance opening 21 for avoiding the limit plate 16 is also provided on the bottom side of the barrel body 1.

[0054] After the barrel body 1 is covered with the outer sleeve 18, the barrel body 1 is adapted to the mixer, so that the mixer can clamp the barrel body 1. The positioning rod 19 is inserted into the positioning hole 20, so that the barrel body 1 can be fixed inside the outer sleeve 18.

[0055] The implementation principle of the sealed barrel for aseptic filling in the embodiment of the present application is as follows: the cover plate 2 covers the top side of the barrel body 1, and the locking assembly 7 clamps the cover plate 2 and the support ring 22, thereby closing the barrel body 1. Then, the material is injected into the barrel body 1 through the feeding assembly 10, thereby reducing the bacterial contamination of the material inside the barrel body 1, thereby improving production efficiency.

[0056] When the material inside the barrel body 1 needs to be taken out for filling, the material is pushed out from the barrel body 1 through the push-out opening 13, thereby reducing the residual amount of the material inside the barrel.

[0057] Example 2.

[0058] The embodiment of the present application discloses a closed barrel for aseptic filling.

[0059] Reference Figure 8 The difference between the sealed material barrel for aseptic filling in the embodiment of the present application and the embodiment 1 is that the locking assembly 7 includes a rotating seat 76, a rotating rod 77 and a clamping plate 78. The rotating seat 76 is fixedly installed on the peripheral side of the support ring 22, one end of the rotating rod 77 is rotatably plugged into the top side of the rotating seat 76, and the rotating rod 77 is limited from being pulled out from the rotating seat 76. One side of the clamping plate 78 is fixedly connected to the rod body of the rotating rod 77. The clamping plate 78 is used to press the top side of the cover plate 2.

[0060] The implementation principle of the sealed barrel for aseptic filling in the embodiment of the present application is as follows: the rotating rod 77 rotates to move the clamping plate 78 away from the top of the cover plate 2, so as to facilitate the cover plate 2 to cover the barrel body 1. After the cover plate 2 covers the top side of the barrel body 1, the rotating rod 77 rotates to allow the two clamping plates 78 to clamp the support ring 22 and the cover plate 2, thereby reducing the cover plate 2 from slipping off the barrel body 1.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
