Processing of rigid shell and flexible liner
Processing a rigid external thread filling opening packaging container shell: the material is plastic and can be formed by blow molding or rotational molding, the material is other material, and the rigid external thread filling opening packaging container shell can be formed by other processing technology.
Processing a flexible inner container: the flexible liner body is made of plastic through a welding process, and an annular interface on the inner side of the lower end of the pipe body of the connecting piece is connected with the flexible liner through welding, so that the connecting piece and the flexible liner form a whole, and the connecting piece becomes a flexible liner opening; exhausting the gas in the welded and connected flexible inner container, folding the flexible inner container into a column shape, wherein the opening of the inner container is one end of the column shape, and sealing the opening of the inner container by a barrel plug.
Second, the assembly method
Assembling a first step: inserting a columnar flexible liner into an injection port of an external thread container shell to enable a connecting piece and the injection port of the packaging container shell to be in a suspension state, opening a barrel plug, inflating the flexible liner into the flexible liner port to enable the flexible liner to expand in volume, and discharging redundant gas between the rigid shell and the flexible liner to enable the flexible liner to be attached to the inner wall of the rigid shell (or enabling the flexible liner to be attached to the inner wall of the rigid shell of the packaging container by pumping the redundant gas between the flexible liner and the inner wall of the rigid shell); after the excessive gas between the flexible inner container and the inner wall of the rigid shell is exhausted, the connecting piece is pressed and buckled on the filling opening of the packaging container downwards, and the assembly of the combined type external thread filling opening packaging container is completed.
Assembling two: inserting the columnar flexible liner with the ventilation opening into an injection opening of a packaging container shell, pressing and buckling the connecting piece downwards on the injection opening of the packaging container shell, opening a rubber plug with the ventilation opening, inflating the liner through the flexible liner opening to expand the flexible liner, discharging redundant gas between the flexible liner and the rigid shell, and attaching the flexible liner to the inner wall of the rigid shell; or the redundant gas between the flexible inner container and the inner wall of the rigid shell can be pumped out through the vent hole on the connecting piece, so that the flexible inner container is pasted on the inner wall of the rigid shell; and after exhausting excessive gas, plugging the ventilation opening by the rubber plug to complete the assembly of the combined external thread filling opening packaging container.
Thirdly, loading and using
Loading a product: the product to be packaged is injected into the combined external thread injection port packaging container, after the product is loaded, the internal thread outer cover is screwed, the flexible inner container port (container port) is sealed through the matching of the external thread on the container injection port and the sealing gasket, and meanwhile, the anti-theft ring on the outer cover is clamped into the rotation stopping teeth of the container port, so that the product is loaded.
Unloading products: the internal thread outer cover is unscrewed in the opposite direction, the anti-theft ring of the outer cover is separated from the cover body (the anti-theft ring cannot be restored) under the action of the rotation stopping teeth of the filling opening of the packaging container, and after the outer cover is opened, the product is unloaded by pouring or using a special tool.
Unloading the flexible inner container: the connecting piece is lifted upwards by using a tool through the notch of the flanging of the connecting piece, so that the connecting piece is separated from the external thread filling opening of the packaging container, gas in the flexible liner is discharged, the volume of the flexible liner is minimized, the flexible liner is drawn out from the filling opening of the packaging container, and unloading is finished. If residual liquid exists in the flexible liner, the drawn flexible liner can be vertically hung for a moment, under the action of gravity, the residual liquid is concentrated at the bottom of the bag, a small opening is formed in the bottom of the bag, the residual liquid can be dripped out, and the liner opening can be inverted to drain the residual liquid.
