Embodiment Construction

[0024] Such as figure 1 As shown, a packaging tube for cosmetics such as lipsticks includes a center beam core 1 and a base 2, and the bottom of the center beam core 1 is inserted into the inner cavity of the base 2. The center beam core of the present invention can be replaced, so it can be replaced from the base 2 and pull it out.

[0025] Such as figure 2 As shown, the center beam core 1 includes a center beam 11, a spiral 12, a fork 13 and a bead 14. The center beam 11 is mainly used for decoration. It is fixedly connected with the spiral 12, and its upper end extends to the top of the center beam core 1. For users, the ends have inner folds, and the lower end extends to the bottom of the center beam core 1 , basically covering the entire center beam core 1 .

[0026] The spiral 12 is a transmission part, and its inner wall is provided with two parallel spiral grooves 121, the fork 13 is a guide, and its side wall is provided with two axially arranged guide grooves 131,...

Abstract

The invention discloses a replaceable middle bundle core and a packaging pipe. The middle bundle core comprises a middle bundle, a spiral part, a fork and a bead which are coaxially arranged. The bottom of the fork is provided with a connecting base capable of being attracted to a magnet, the middle bundle extends to the vicinity of the bottom edge of the connecting base, and correspondingly the connecting base is basically hidden in the middle bundle; the bottom surface of the connecting base is provided with a positioning hole, and the diameter of the connecting base is greater than that ofthe fork. The diameter of the connecting base is greater than that of the fork, and therefore contact between the fork and the middle bundle can be effectively avoided; because the connecting base isrelatively low, the length of the part, in contact with the middle bundle, of the connecting base is limited, and even if the connecting base is in contact friction with the middle bundle, the resistance is small, so that the arrangement of a rotating torsion force of the middle bundle core is not influenced.

Description

technical field [0001] The invention relates to a lipstick packaging tube, in particular to a replaceable center beam core and the packaging tube. Background technique [0002] Lipstick is a common cosmetic, which generally consists of a packaging tube and a lipstick cream inside. A common packaging tube has three parts: a base, a top cover, and a center beam core. The bottom of the center beam core is inserted into the base and fixedly connected to it. The top cover cooperates with the base to form a sealed cavity surrounding the center beam core. [0003] For example, CN203662193U discloses a lipstick tube with magnets, including a cover, a base, and a middle beam core. The middle beam core includes beads, forks, spirals and middle beams that are coaxially threaded from the inside to the outside. The beam is made of magnetic material, and the inside of the cover is provided with a ring magnet that is attracted to the mouth of the middle beam. [0004] Because the paste i...
