Embodiment 1

[0035] Such as figure 1 As shown, a packaging tube includes a center beam core 1 and a base 2 , the bottom of the center beam core 1 is inserted into the inner cavity of the base 2 , and the top of the base 2 is exposed. A cover (not shown in the figure) is generally provided on the top, and the cover cooperates with the base 2 to form a cavity surrounding the center beam core 1 .

[0036] Such as figure 2 and 3 As shown, the center beam core 1 includes a center beam 11, a helix 12, a fork 13 and a bead 14 coaxially and sequentially threaded. The arranged guide groove 130 and the beads 14 are used to hold the lipstick paste, and the outer surface thereof has a protrusion 140 extending through the guide groove 130 into the spiral groove 120 , and the middle bundle 11 is fixedly connected with the spiral 12 .

[0037] The outer peripheral surface of the fork 13 is provided with limiting steps 131, 132 that cooperate with the end surfaces of the two ends of the helix 12, so t...

Abstract

The invention discloses a median bundle core and a packaging pipe. The median bundle core includes a bead, a fork, a spiral and a median bundle which are sequentially arranged from inside to outside.The bottom of the fork is provided with a connecting base, the bottom end face of the connecting base is provided with a groove, the inner side wall of the groove is provided with a clamping groove, the bottom surface of the groove is provided with a positioning hole, and the bottom of the median bundle extends in the axial direction and is close to the bottom edge of the connecting base or completely surrounds the connecting base. The packaging pipe includes a base and the median bundle core. During use, the bottom of the median bundle core is inserted in an inner chamber of the base, a connector matched with the clamping groove is disposed in the base, and the top surface of the connector is provided with a positioning block inserted in and matched with the positioning hole. The median bundle core and the base are clamped with each other, the connecting base is substantially hidden in the median bundle, the median bundle core cannot be used alone, but the median bundle core can be replaced, and the base is reused.

Description

technical field [0001] The invention relates to a packaging tube, in particular to a cosmetic packaging tube with a replaceable center beam core. Background technique [0002] The existing lipstick packaging tube is generally composed of a top cover, a base and a middle beam core, wherein the base and the middle beam core are fixedly connected, and the top cover and the base cooperate to form a cavity surrounding the middle beam core. [0003] For example, CN206621001U discloses a tubular lipstick casing in a rotating magic way, the inner side wall of the inner base is snap-fitted and fixedly connected with the middle beam core assembly through the first buckle structure, and the outer side wall of the inner base is connected with the inner side wall of the inner cover through the second buckle structure. Snap-type positioning connection; the upper part of the outer peripheral side wall of the inner cover is connected with the inner peripheral side wall of the upper cover th...
