A flanging 133 is arranged on the side wall of the through hole 131, and a first buckle 134 is arranged on the flanging 133. During assembly, the pumping-out assembly 5 passes through the through hole 131, the top surface of the flange 511 abuts against the flanging 133, the second buckle 512 is matched with the first buckle 134 to fix the pump core, and the whole pumping-out assembly 5 is fixed in the through hole 131 of the connecting piece 13 of the shoulder sleeve 1. In the figure, the first buckle and the second buckle are mutually matched concave-convex structures. In this embodiment, after the external thread 23 of the hose 2 and the internal thread 132 on the inner wall of the through hole 131 are in perfect fit, the bottom end of the pump core 51 breaks through the cross-shaped breaking slot of the sealing sheet 24 and communicates with the interior of the hose 2. After the pressing cover 53 is repeatedly pressed, the liquid may flow out from the liquid outlet hole 531. Of course, the sealing sheet 24 here may also be replaced by a sealing film, and the bottom end of the pump core 51 can achieve the same effect by only puncturing the sealing film. A detachable bottle cap may also be adopted for replacing the sealing sheet 24, and during use, the bottle cap is removed, and then the hose 2 is assembled on the shoulder sleeve 1. In addition, in this embodiment, the assembly position of the flange 511 may be set at the tail end of the upper side of the internal thread 132. After the hose 2 is completely assembled, the top surface of the liquid outlet end of the hose 2 abuts against the bottom surface of the flange 511, so that the fixation of the pump core 51 is firmer.

In order to facilitate disassembly, notched slots 33 may be arranged at the left and right sides of the protrusion 32, so that when the protrusion 32 and the groove 124 are in snap fit or disassembled, the cylinder wall at the protrusion 32 deforms. In addition, positioning ribs 125 matched with the notched slots 33 may also be arranged on the inner side of the third side wall 123 of the shoulder sleeve 1, as shown in Fig. 3, and can play the role of identifying the direction for positioning. A hand position for disassembly 126 may also be arranged at the outer side of the third side wall 123 of the shoulder sleeve, and at the same time, an arrow 127 is set for indicating the disassembly direction. The outer cylinder may also be provided with an air hole, in this way, in the process that as the contents are pumped out, the volume of the hose is continuously reduced, the outside air may enter the outer cylinder so as to prevent negative pressure from being produced in the outer cylinder for causing the contents be inconvenient to pump out.

[0025] The operation process of the refillable container in the embodiment of the present invention is shown in Fig. 8. Liquid is filled from a liquid inlet. Preferably, the size of the liquid inlet is adjustable. After the filling is completed, the liquid inlet is closed up and sealed, and then the outer cylinder is assembled. During use, the cylinder cover is removed, the pressing cover is pressed, the pump core sucks out the contents, the hose shrinks and deforms automatically, and then air enters the outer cylinder from the air inlet of the outer cylinder, so as to prevent negative pressure from being produced in the outer cylinder. During the whole use process, air does not enter the hose to contaminate the contents, which ensures the quality and shelf life of the product. After the contents are used up, the outer cylinder is disassembled, and then the hose is unscrewed from the shoulder sleeve for replacement, so that the operation is convenient and practical.

[0026] The above description is only preferred embodiments of the present invention and is not intended to limit the present invention.
