Theshoulder sleeve 1 includes atop wall 11 and aside wall 12 bent and extending downward from the edge of thetop wall 11. The liquid outlet end of thehose 2 is detachably connected to the inner side of thetop wall 11, and theouter cylinder 3 accommodates thehose 2 therein and is detachably connected to theside wall 12 from the lower side. Thecylinder cover 4 is detachably buckled on theshoulder sleeve 1 from the upper side and is connected with theside wall 12 of theshoulder sleeve 1. - The packaging container of the present invention includes an outer package composed of the
shoulder sleeve 1, theouter cylinder 3 and thecylinder cover 4 and an inner package composed of thehose 2, and thehose 2 is detachably connected with the outer package. After the contents of thehose 2 are used up, thehose 2 can be replaced with ahose 2 full of liquid, and the outer package can be reused, so that the packaging cost of products can be greatly reduced, and the produced waste can be reduced. - Specifically, the present invention provides an embodiment of detachable connection of a
hose 2, as shown inFig. 3 . A connectingpiece 13 is arranged on thetop wall 11 of theshoulder sleeve 1, the connectingpiece 13 penetrates into theshoulder sleeve 1 from thetop wall 11, the connectingpiece 13 is provided with a throughhole 131 with the axis being in the up-down direction, the side wall of the throughhole 131 is provided with aninternal thread 132 close to the liquid outlet end of the hose, and the liquid outlet end of thehose 2 is provided with anexternal thread 23 matched with theinternal thread 132. In this embodiment, the shape of the connectingpiece 13 being cylindrical is taken as an example, and can also be square, oval or other unconventional shapes in practical application, and the present invention does not make limitation thereto. - Specifically, the structure of an embodiment of a
hose 2 is shown inFig. 4 which is a sectional view of a liquid outlet end. Thehose 2 includes aliquid outlet 21 which is arranged inside thehose 2 and close to the liquid outlet end; asealing sheet 24 is arranged at theliquid outlet 21, and the sealing sheet is provided with a cross-shaped breaking slot, as shown inFig. 5 . - Preferably, a pumping-
out assembly 5 can also be arranged to pump out the liquid in thehose 2 from theliquid outlet 21, as shown inFig. 5 , the pumping-outassembly 5 is fixed in the throughhole 131, and the assembly diagram is shown inFig. 6 . In order to observe the structure conveniently, the pumping-outassembly 5 is shown upside down inFig. 5 . Specifically, the pumping-outassembly 5 includes apump core 51 and apressing cover 53, the middle part of thepump core 51 is provided with aflange 511, and the upper side of theflange 511 is provided with asecond buckle 512. Thepressing cover 53 sleeves the top of thepump core 51 and is provided with aliquid outlet hole 531. Aflanging 133 is arranged on the side wall of the throughhole 131, and afirst buckle 134 is arranged on theflanging 133. During assembly, the pumping-outassembly 5 passes through the throughhole 131, the top surface of theflange 511 abuts against theflanging 133, thesecond buckle 512 is matched with thefirst buckle 134 to fix the pump core, and the whole pumping-outassembly 5 is fixed in the throughhole 131 of the connectingpiece 13 of theshoulder sleeve 1. In the figure, the first buckle and the second buckle are mutually matched concave-convex structures. In this embodiment, after theexternal thread 23 of thehose 2 and theinternal thread 132 on the inner wall of the throughhole 131 are in perfect fit, the bottom end of thepump core 51 breaks through the cross-shaped breaking slot of thesealing sheet 24 and communicates with the interior of thehose 2. After the pressingcover 53 is repeatedly pressed, the liquid may flow out from theliquid outlet hole 531. Of course, the sealingsheet 24 here may also be replaced by a sealing film, and the bottom end of thepump core 51 can achieve the same effect by only puncturing the sealing film. A detachable bottle cap may also be adopted for replacing the sealingsheet 24, and during use, the bottle cap is removed, and then thehose 2 is assembled on theshoulder sleeve 1. In addition, in this embodiment, the assembly position of theflange 511 may be set at the tail end of the upper side of theinternal thread 132. After thehose 2 is completely assembled, the top surface of the liquid outlet end of thehose 2 abuts against the bottom surface of theflange 511, so that the fixation of thepump core 51 is firmer. - The present invention further provides an embodiment of the
shoulder sleeve 1, theouter cylinder 3 and thecylinder cover 4 which are detachable. Specifically, as shown inFig. 2 andFig. 3 , theside wall 12 of theshoulder sleeve 1 includes afirst side wall 121 bent and extending downward from the edge of thetop wall 11, asecond side wall 122 extending outward along the edge of thefirst side wall 121, and athird side wall 123 bent and extending downward along the edge of thesecond side wall 122; astep 31 is arranged at the opening end of theouter cylinder 3, as shown inFig. 7 , when theouter cylinder 3 is covered with theshoulder sleeve 1, the end part of thethird side wall 123 of theshoulder sleeve 1 abuts against thestep 31, and when thecylinder cover 4 covers theshoulder sleeve 1, the end part of thecylinder cover 4 abuts against the second side wall of theshoulder sleeve 1. - Furthermore, a
protrusion 32 may be arranged on the outer wall of theouter cylinder 3, and theprotrusion 32 is located between thestep 31 and the opening of theouter cylinder 3; meanwhile, agroove 124 matched with theprotrusion 32 is formed in the inner side of thethird side wall 123 of theshoulder sleeve 1. In order to facilitate disassembly, notchedslots 33 may be arranged at the left and right sides of theprotrusion 32, so that when theprotrusion 32 and thegroove 124 are in snap fit or disassembled, the cylinder wall at theprotrusion 32 deforms. In addition, positioningribs 125 matched with the notchedslots 33 may also be arranged on the inner side of thethird side wall 123 of theshoulder sleeve 1, as shown inFig. 3 , and can play the role of identifying the direction for positioning. A hand position fordisassembly 126 may also be arranged at the outer side of thethird side wall 123 of the shoulder sleeve, and at the same time, anarrow 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. - 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.
