Detailed Description

The lipstick core according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims.

Referring to fig. 1 and 2, in one embodiment, a lipstick middle bundle core includes a base 1, a middle sleeve 2, a middle bundle case 4, a lipstick barrel 3, and a support.

The middle-bundle shell 4 is sleeved at the top end of the middle sleeve 2. The middle sleeve 2 is sleeved on the top end of the base 1, and the base 1 is rotatably connected with the middle sleeve 2. A gap is left between the bottom end of the middle sleeve 2 and the outer surface of the base 1. The lipstick barrel 3 is connected with the inner cavity of the middle bundle shell 4 in a sliding manner, the bottom of the lipstick barrel is connected with a screw rod 5, and the screw rod 5 is in threaded connection with the inner cavity of the base 1.

The supporting part is arranged in the gap and is respectively connected with the outer surface of the base 1 and the inner circular surface of the bottom end of the middle sleeve 2.

This embodiment is by base 1, well cover 2, well bundle of shell 4, lipstick bucket 3, supporting part constitution lipstick well bundle core to clearance department between well cover 2 and base 1 has set up the supporting part, is the intermediate part between well cover 2 and the base 1 by the supporting part, thereby when making base 1 rotatory for well cover 2, it is rotatory more stable, user torsion is softer when wrench movement base 1, has solved current lipstick well bundle core unstable problem when the rotation.

The specific structure of the bundle core in the lipstick of the present embodiment is further explained below:

in this embodiment, the supporting portion may be a ring-shaped member 6, such as a ring-shaped sheet, an outer edge of the ring-shaped member 6 is disposed on an inner circumferential surface of the bottom end of the middle sleeve 2, and the inner circumferential surface is in contact with the outer surface of the base 1, so that when the base 1 rotates, the supporting portion supports the base 1 to stabilize the rotation of the base 1; or on the outer surface of the base 1, the outer edge is contacted with the middle sleeve 2, thereby generating a supporting effect when rotating. The ring member 6 may be formed integrally with the middle sleeve 2, or may be formed by forming an annular groove on the middle sleeve 2, and the ring member 6 is embedded in the annular groove, and may also be formed integrally on the base 1, which is not limited herein.

The ring member 6 is usually made of a material having a certain elasticity, such as plastic, and can be bent in the gap after being assembled, so as to ensure the supporting effect.

Referring to fig. 2, in the present embodiment, the screw rod 5 is provided with an external thread 7, and the inner cavity of the base 1 is provided with an internal thread, so as to realize a threaded connection between the two. Wherein, the end of the external thread 7 facing away from the lipstick barrel 3 is the tail end. Set up at the tail end department of external screw thread 7 and move back a tooth locating part 8 for the external screw thread 7 breaks away from the internal thread, avoid the user after rotating lipstick bucket 3 to the highest position, continue the rotation and lead to external screw thread 7 and internal thread to break away from, the condition emergence that lipstick bucket 3 can't be screwed in once more.

Specifically, the tooth-withdrawing limiting part 8 can be a limiting block, and the limiting block is arranged between adjacent screw teeth of the external screw thread 7. And the face of this stopper orientation screw-out direction is perpendicular to the helix of external screw thread 7, is perpendicular to rotation axis promptly, and after lipstick bucket 3 screwed out to the highest position, the internal thread tail end on the base 1 can contact with this stopper promptly, and because the face that contacts is the vertically face, the internal thread can't continue the motion relatively external screw thread 7, can realize preventing moving back the mesh of tooth. The surface facing the screwing direction can be an inclined surface 9 for guiding the screwing of the external thread 7 and the internal thread, so that the top end of the internal thread can be screwed in through the inclined surface 9 during assembly, thereby realizing threaded connection.

The utility model discloses a restraint core in lipstick is equipped with first arch on the outer disc of well cover 2, and it has corresponding first recess to open on the inner chamber wall of well bundle shell 4. The first protrusion 7 can also be an oblique block, the surface facing the top end of the middle bundling shell 4 is an oblique surface, and the surface facing the bottom end of the middle bundling shell 4 is perpendicular to the outer circular surface of the middle sleeve 2. During the assembly, in first protruding joint and the first recess, the inclined plane can be convenient for well cover 2 to insert in restrainting shell 4 in, and the face of cover 2 then can cooperate with the wall of first recess in the perpendicular to, prevents that well cover 2 breaks away from in restrainting shell 4.

The utility model discloses a restraint core in lipstick, the bottom department of the interior disc of well cover 2 is equipped with the second recess, and it is protruding to be equipped with corresponding second on base 1's the surface. The second protrusion can also be an oblique block, the surface facing the top end of the base 1 is an oblique surface, and the surface facing away from the top end of the base 1 is perpendicular to the outer circular surface of the base 1. During the assembly, the protruding joint of second is in the second recess, and the inclined plane can be convenient for base 1 to insert in cover 2, and the face of perpendicular to base 1 then can with the wall cooperation of second recess, avoid base 1 to break away from in cover 2.

The utility model discloses a restraint core in lipstick is equipped with a plurality of damping archs on the outer disc of well cover 2, during the assembly for realize interference fit with the internal face of well bundle shell 4, thereby cover 2 and the relative motion between the well bundle shell 4 in the restriction.

The utility model discloses a restraint core in lipstick, well bundle shell 4 is restrainted or flat well in the slope.

The lipstick middle bundle core of the utility model is composed of a base 1, a middle sleeve 2, which can be made of polypropylene material or other materials. Further, the material of the member such as the middle bundle case 4 may be aluminum or other materials, and is not particularly limited herein.

The utility model discloses a pencil core in lipstick is equipped with a plurality of vertical stripes on base 1's the outer disc for increase the roughness of the outer disc of base 1, so that the user rotates base 1, in order to drive

screw rod

5 and 3 motions of lipstick bucket, thereby realize stretching out and retracting of lipstick.
