DETAILED DESCRIPTION

[0028] The preferred embodiments of the utility model are described in detail below with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0029] As Figures 1-8 shown is a carton 1 soft bag filling assembly described in the embodiment, including carton 1, fixing seat 2, packaging bag 7. The carton 1 is internally hollow structure, and the carton 1 is adapted to the packaging bag 7. In the specific filling, the packaging bag 7 is placed in the carton 1 to fill the material in the packaging bag 7. The top of the carton 1 is processed with an assembly port 11. The packaging bag 7 without filling material can enter the inside of the carton 1 through the assembly port 11.

[0030] The aforementioned fixing seat 2 is installed in the assembly opening 11. The four peripheral sidewalls of the fixing seat 2 are in clearance fit with the assembly opening 11. The fixing seat 2 is processed with a through hole 22 penetrating from top to bottom. The inner peripheral wall of the through hole 22 is processed with a plurality of elastic deformation portions 24 in circumferential direction. The first end of the elastic deformation portion 24 is fixedly connected with the inner peripheral wall of the through hole 22, and the second end extends from the inner peripheral wall of the through hole to the central position of the through hole to form a free end. The free ends of the elastic deformation portions 24 enclose a limiting space 23. In the embodiment, the elastic deformation portion 24 is a plastic sheet structure, and has a designed length so that the elastic deformation portion 24 has a rebound force in the direction of the central axis of the through hole 22. The aforementioned fixing seat 2 is processed with a limiting top edge 21 extending outward. The limiting top edge 21 is located above the carton 1 and is in upper and lower limiting fit with the carton 1. Through the limiting of the limiting top edge 21, the movement of the fixing seat 2 towards the inside of the carton 1 can be limited.

[0031] In the embodiment, the packaging bag 7 is a soft packaging component, which is a conventional component in the prior art. The packaging bag 7 has a bag opening. The valve seat 3 is fixed on the bag opening. The connection manner of the valve seat 3 and the packaging bag 7 is known in the prior art. The inside of the valve seat 3 is processed with a fluid passage 31 communicating with the bag opening. The two ends of the fluid passage are both open, the first end of which communicates with the bag opening, and the second end forms a material inlet. The filled material can only enter through the material inlet and enter the packaging bag 7 through the bag opening. The diameter of the aforementioned limiting space 23 is matched with the outer diameter of the valve seat 3, and the valve seat 3 can be inserted into the limiting space 23 from bottom to top. The outer peripheral wall of the valve seat 3 is processed with a limiting flange 32. When the valve seat 3 is inserted, the limiting flange 32 pushes the elastic deformation portion 24 to move to the position above the elastic deformation portion 24, and the elastic deformation portion 24 is returned to form an upper and lower limiting fit with the limiting flange 32. Through the limiting of the elastic deformation portion 24, it is difficult for the valve seat 3 to be separated downward from the fixing seat 2, thereby fixing the valve seat 3 on the carton 1.

[0032] In the specific structure design, the outer diameter of the aforementioned limiting flange 32 is smaller than the inner diameter of the through hole 22 and larger than the diameter of the limiting space 23.

[0033] In the embodiment, the fixing seat 2 is processed with a concave cavity 27 with an open top. The aforementioned through hole 22 is formed in the bottom of the concave cavity 27. When the valve seat 3 is inserted into the limiting space 23, the valve seat 3 is accommodated into the concave cavity 27 to protect the valve seat 3.

[0034] The valve cover 4 is matched with the valve seat 3. The valve cover 4 is threadedly connected with the valve seat 3 and seals one end of the fluid passage 31. The valve cover 4 is unscrewed before filling to perform the filling operation. After filling, the valve cover 4 is screwed onto the valve seat 3 to seal the packaging bag 7.

[0035] In the embodiment, the elastic part 25 is formed on at least one side of the fixing seat 2. The first end of the elastic part 25 is fixedly connected with the fixing seat 2, and the second end is located outside the side of the fixing seat 2 and forms a free end. Through reasonable structure design, the free end of the elastic part 25 has a rebounding force in the inside-outside direction of the fixing seat 2. The free end of the elastic part 25 is arranged to face the limiting top edge 21, and a first limiting gap 5 is formed between the two. The first limiting gap 5 is matched with the wall thickness of the carton 1. When the fixing seat 2 is inserted into the assembly opening 11, the edge of the assembly opening 11 is inserted into the first limiting gap 5 through the contraction rebounding of the elastic part 25, so as to realize the up-down limiting of the fixing seat 2 on the carton 1. In the embodiment, the elastic part 25 is arranged on three adjacent sides of the fixing seat 2. And a first limiting gap 5 is formed corresponding to each elastic part 25, so as to be able to limit the three sides of the fixing seat 2 up and down.

[0036] The side surface of each elastic part 25 facing the outside of the fixing seat 2 is machined with a guide slope 251. The guide slope 251 extends from the fixing seat 2 to the free end of the elastic part 25, and gradually away from the outside surface of the fixing seat 2. When the fixing seat 2 is inserted into the assembly opening 11, the guide slope 251 is in contact with the edge of the assembly opening 11, so that the elastic part 25 can pass smoothly.

[0037] The bottom of the side opening 12 is closed, and the top end of the side opening 12 is in communication with the assembly opening 11 on the top surface of the carton. The fixing seat 2 is machined with a limiting side edge 26 extending outward. The limiting side edge 26 is located outside the front side wall of the carton 1. The bottom of the fixing seat 2 is formed with a limiting protrusion 28. The limiting protrusion 28 is located inside the front side wall of the carton 1. The second limiting gap 6 is formed between the limiting protrusion 28 and the limiting side edge 26. The second limiting gap 6 is matched with the wall thickness of the carton 1. When the fixing seat 2 is inserted into the assembly opening 11, the bottom edge of the side opening 12 is inserted into the second limiting gap 6, so as to realize the front-rear limiting of the fixing seat 2 on the carton 1, and further limit the movement of the fixing seat 2 in the assembly opening 11.

[0038] In the embodiment, the distance between the first limiting gap 5 and the second limiting gap 6 is reasonably designed, so as to realize the smooth assembly and disassembly of the fixing seat 2 on the carton 1.

[0039] In specific use, the valve seat 3 on the packaging bag 7 is inserted into the limiting space 23 on the fixing seat 2 in advance to limit the valve seat 3 on the fixing seat 2. Then the whole structure is installed on the carton 1. The empty packaging bag 7 enters the inside of the carton 1 through the assembling opening 11, and the fixing seat 2 is inserted into the assembling opening 11. The limiting top edge 21 and the elastic part 25 are matched to limit the fixing seat 2 on the carton 1 upward and downward. The limiting side edge 26 and the limiting protrusion 28 are matched to limit the fixing seat 2 on the carton 1 forward and backward. Then the filling equipment fills the chemical materials into the packaging bag 7 through the valve seat 3. During the filling, the packaging bag 7 is automatically expanded in the inside of the carton 1. Through the above structure design, the valve seat 3 can be limited and fixed on the carton 1, so that the chemical materials can be filled through the valve seat 3, and the on-site auxiliary filling of the operation personnel is not needed, and the non-contact filling operation of the chemical materials is realized. The whole structure uses the carton 1 and the packaging bag 7 to package the chemical materials, the carton 1 and the packaging bag 7 are convenient to recycle, the recycling cost is saved, the recycling efficiency is high, and the packaging application requirement of the chemical materials is effectively met.
