The second connecting sleeve 220 is sleeved inside the opening 130 of the bag body 100 and fixed by welding. The outer surface of the second connecting sleeve 220 is connected to the inner surface of the opening 130. The outer diameter of the first connecting sleeve 210 is larger than the outer diameter of the second connecting sleeve 220, so as to form a stepped platform 230 on the outer peripheral wall of the interface 200. The stepped platform 230 is used to fit with the Beta valve. Optionally, the bottom end of the second connecting sleeve 220 is connected to the top end of the bag body 100 by welding; optionally, the inner surface of the second connecting sleeve 220 is connected to the outer surface of the opening 130.

[0027] The utility model provides a quick docking bag with an interface. Compared with the prior art, the bag body 100 is provided with an opening 130, and the interface 200 is composed of a first connecting sleeve 210 and a second connecting sleeve 220. The opening 130 is sleeved and welded on the outside of the second connecting sleeve 220, so as to achieve a sealed connection between the bag body 100 and the interface 200. The first connecting sleeve 210 and the second connecting sleeve 220 form a stepped clamping platform 230 on the outer peripheral wall of the interface 200, and the stepped clamping platform 230 is clamped and matched with the Beta valve to achieve a sealed connection. The utility model provides a quick docking bag with an interface, which can achieve quick docking with a stainless steel Beta valve, ensure that the material will not leak, and prevent the material from causing harm to the human body during the transfer process.

[0028] Specifically, the bag body 100 includes a first sheet layer 110 and a second sheet layer 120 , the edges of the first sheet layer 110 and the second sheet layer 120 are heat-sealed to form a transfer chamber inside the bag body 100 , and the bag body 100 is provided with an opening 130 connected to the transfer chamber.

[0029] See also Figure 3 In the first embodiment, the first sheet 110 is a light-transmitting layer, and the second sheet 120 is a light-blocking and breathable layer. Specifically, the first sheet 110 is a barrier layer with a thickness of 80 μm-90 μm, which is made by a blow molding process, and a high-density polyethylene film that can block bacteria but is breathable is made by flash evaporation of high-density polyethylene particles. The air permeability is tested by the Gurley method: the time for 100 cc of gas to pass through is 14-20 seconds.

[0030] In the second embodiment, the first sheet 110 and the second sheet 120 are both light-transmitting layers. Specifically, the first sheet 110 and the second sheet 120 are both made of low-density polyethylene particles, and a 80-200 μm thick film is obtained by a film blowing process. The first sheet 110 and the second sheet 120 are cut and heat-sealed to obtain a bag body 100 of a desired shape and appropriate specifications.

[0031] The bag body 100 in the above two embodiments can withstand high-temperature steam sterilization at 121°C for 30 minutes after docking with the stainless steel Beta valve. After sterilization, it is convenient to transfer and can meet the requirements of aseptic feeding after docking with the α valve, so as to meet the requirements of rapid, aseptic and closed transfer of products.

[0032] Please refer to Figure 1 and Figure 2, the bag body 100 is rectangular or T-shaped. When the bag body 100 is rectangular, the opening 130 is separately provided on the first sheet 110 or the second sheet 120 of the bag body 100; when the bag body 100 is T-shaped, the opening 130 is provided on one side of the narrow end of the bag body 100 and is located between the first sheet 110 and the second sheet 120.

[0033] In order to facilitate the discharge of materials in the transfer chamber, a material guide tube 140 is connected to the side of the bag body 100 near the opening 130. One end of the material guide tube 140 is connected to the transfer chamber, and the other end of the material guide tube 140 is a free end. The free end of the material guide tube 140 can pass through the interface 200 and pull the material guide tube 140 to the outside of the interface 200, thereby guiding the material to be discharged from the transfer chamber to the outside of the bag body 100. It has the function of guiding materials, and the objects in the bag can be smoothly introduced into the required place through the material guide port. The bag body 100 with the opening 130 is manufactured by a heat sealing process, and the opening 130 of the bag body 100, the material guide port and the interface 200 are then heat-sealed to obtain a bag containing an interface.

[0034] Please refer to Figure 4 The first connecting sleeve 210 and the second connecting sleeve 220 are coaxially arranged so that the width of the stepped platform 230 in the circumferential direction of the interface 200 is consistent, and the first connecting sleeve 210 and the second connecting sleeve 220 have the same inner diameter, so that the first connecting sleeve 210 and the second connecting sleeve 220 can smoothly transition on the inner wall of the interface 200 without the presence of a stepped platform, thereby avoiding the situation of blocking and jamming when the material is discharged. In addition, the axial length of the second connecting sleeve 220 is greater than the axial length of the first connecting sleeve 210, which can ensure that the second connecting sleeve 220 has a sufficient length, so that it has a larger contact area with the opening 130, thereby improving the connection strength between the interface 200 and the bag body 100. Preferably, the axial length of the second connecting sleeve 220 is greater than twice the axial length of the first connecting sleeve 210.

[0035] When the opening 130 is sleeved on the outside of the second connecting sleeve 220, the end of the opening 130 abuts against the stepped clamping platform 230, which can completely cover the second connecting sleeve 220, providing more welding area between it and the second connecting sleeve 220, and ensuring the structural strength of the connection between the two.

[0036] Preferably, refer to Figure 5A plurality of annular ridges 240 are provided on the outer peripheral wall of the second connecting sleeve 220, and the plurality of annular ridges 240 are integrally formed on the outer peripheral wall of the second connecting sleeve 220. In addition, the plurality of annular ridges 240 are arranged in sequence and at equal intervals along the axial direction of the second connecting sleeve 220. The inner diameter of the opening 130 is larger than the outer diameter of the second connecting sleeve 220 but slightly smaller than the outer diameter of the annular ridges 240. When the opening 130 is sleeved on the second connecting sleeve 220, it is necessary to enlarge its own outer diameter through elastic deformation, and then sleeved on the plurality of annular ridges 240. The opening 130 can hold the second connecting sleeve 220 tightly by its own elastic restoring force, ensuring that the two have a higher bonding strength, and finally welding is performed.

[0037] In addition, an annular groove 250 is provided on the outer peripheral wall of the second connecting sleeve 220, and the annular groove 250 is located on the side of the second connecting sleeve 220 close to the first connecting sleeve 210. After the opening 130 passes through a plurality of annular ridges 240, the opening 130 is elastically deformed outward in the circumferential direction, and after the end of the opening 130 passes through all the annular ridges 240, a corresponding rebound will occur, especially after the welding is completed, the rebound amount of the end of the opening 130 will be greater, at this time, the end of the opening 130 can be retracted from the annular groove 250, so that the appearance of the connection between the opening 130 and the interface 200 is more beautiful, and the flange of the opening 130 is avoided to affect the connection strength between the two.

[0038] Preferably, the interface 200 can be selected in the following specifications: outer diameter 120mm, 190mm, 270mm, 350mm, so as to meet the requirements of docking with 120mm, 190mm, 270mm, 350mm stainless steel Beta valves.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
