Description
Technical field
The utility model relates to a kind of packaging tube.
Background technology
Present packaging tube can only a kind of content of can in same flexible pipe, along with hose packing market is flourish, and content kind various, hose packing requires also to increase day by day, and existing flexible pipe has not satisfied the market demand.
Summary of the invention
The purpose of this utility model be can only a kind of content of can in same flexible pipe at existing packaging tube shortcoming, a kind of tube-in-tube flexible pipe that can two kinds of contents of can in same hose packing is provided.
The purpose of this utility model is achieved in that the utility model comprises outer tube, interior pipe and enclosing cover, pipe is positioned within the outer tube in described, outside tube head and interior tube head be respectively equipped with the button bit that matches make outer tube and interior caliber to and axial location, tube head also is provided with gear and matches with the gear of interior tube head outside, make outer tube and interior tubular axis to the location, between the top of the top of interior pipe and outer tube, be provided with die cavity; Be respectively equipped with fluid hole at the top of outer tube, the top of interior pipe, the tube head medial surface is provided with top die cavity of liquid outlet groove connection and following outer tube tube chamber outside; Described enclosing cover covers on the head of outer tube, and they are by the connection that matches of screw thread or button bit, is provided with needle seal at the inner top surface of enclosing cover and inserts in the outer tube fluid hole and be sealed and matched.
The utility model has two kinds: a kind of is that the content of interior pipe and outer tube is extruded the back mixed type, it is to be provided with out fluid column at the top of interior pipe, the top of interior pipe fluid hole is positioned at the end face of fluid column, goes out fluid column and extends upwardly in the outer tube fluid hole, and interior pipe fluid hole directly communicates with the outer tube fluid hole.Like this, the content of outer tube flows to the outer tube fluid hole by the liquid outlet groove of flowing through in the outer tube tube chamber through die cavity, and the content of interior pipe is flowed out from the outer tube fluid hole by pipe fluid hole in flowing through in the interior pipe tube chamber.Two kinds of contents do not mix in pipe substantially.
Another kind is an extrusion type after the contents mixed of interior pipe and outer tube, it is across die cavity between interior pipe fluid hole and outer tube fluid hole, the outer tube content liquid outlet groove of flowing through in the outer lumen flows to die cavity, interior pipe content flows to die cavity from interior pipe fluid hole, flows to the outer tube fluid hole after two kinds of contents mix and flow out in die cavity.
Technique effect of the present utility model is: the utility model also comprises an independently little fully flexible pipe in outer tube, and two kinds of different formulations contents of can are so simultaneously realized the function that two kinds of contents are deposited respectively, used simultaneously.This product can be used for cosmetic package, daily necessities packing and the medical packaging etc. of different use occasions.
