Description
Technical Field
The present invention relates to a cosmetic container. In particular to a middle binding device for a stick-shaped cosmetic container such as lipstick, lip gloss, stick-shaped eye shadow, stick-shaped foundation, perfume bottle, emulsion and the like.
Background
The container for lipstick and the like is composed of a bottom cover member, an external screw member made of synthetic resin and having a ring of internal thread at the lower end of the bottom cover, an internal screw member made of synthetic resin and having a ring of internal thread at the inner part of the external screw member, a middle dish member made of synthetic resin and inserted into the internal screw member, a metal outer tube member fitted over the outer circumference of the external screw member, the internal screw member and the middle dish member, and a rubber O-ring fitted over the external screw member.
However, this structure has the following disadvantages:
In the existing cosmetic container manufacturing, for the purpose of simple mold manufacturing, the internal thread of the screw component (comprising an external screw and an internal screw) is only provided with one circle of threads, when the internal thread of the screw component is matched with the external thread of the corresponding component, the contact area between the two sides of the screw component is too small, so that when the product is lifted to the upper limit and the lower limit, the product is slightly shaken and dynamic, and abnormal sound is generated. If the shaking feeling is reduced by reducing the clearance between the two square threads, the friction between the two square threads is increased.
The two conditions do not affect the various functions of the cosmetic container. However, the sound and the shaking feeling generated by the cosmetic container may cause consumers to misunderstand that the internal structure of the cosmetic container is damaged, and the quality of the cosmetic container may be questioned; the texture of the cosmetics is reduced, and the high-grade feeling of brands is reduced.
Disclosure of Invention
The invention aims to provide a middle beam device of a cosmetic container, which can reduce shaking feeling and rotation abnormal sounds when in rotation use.
The technical scheme adopted by the invention is as follows: the middle binding device of the cosmetic container comprises a middle dish part, an inner spiral part, an outer spiral part and an outer cylinder part which are sequentially nested from inside to outside, wherein a rubber O ring which plays a role in rotation damping is arranged between the outer spiral part and the outer cylinder part, and the outer spiral part is in threaded connection with an outer thread of an inner spiral part outside the inner spiral part through an inner thread of the outer spiral part on the inner side so that the inner spiral part can rotate and lift; the middle dish component is in threaded connection with the internal threads of the internal screw component at the inner side of the internal screw component through an external threaded rod integrally formed at the lower part, so that the middle dish component can rotate and lift; the guide vertical rib on the outer side of the upper part of the middle dish part can be vertically and slidably embedded into the guide vertical groove on the inner side of the outer cylinder part, the inward convex side pressing transverse rib on the inner side of the outer cylinder part is embedded into the inward concave side pressing transverse groove on the outer side of the outer screw part, so that the outer cylinder part and the outer screw part are not mutually decomposed when horizontally rotating, and the number of turns of threads on the inner screw part, the outer screw part, the inner screw part and the outer screw rod are all more than 1.
The middle binding device of the cosmetic container comprises a middle dish part, an outer spiral part and an outer cylinder part which are nested in sequence from inside to outside, wherein a rubber O ring which plays a role of rotation damping is arranged between the outer spiral part and the outer cylinder part, and the outer spiral part is in threaded connection with an outer threaded rod integrally formed at the lower part of the middle dish part through an inner thread of the outer spiral part at the inner side so that the middle dish part can rotate and lift; the guide vertical rib on the outer side of the upper part of the middle dish part can be vertically and slidably embedded into the guide vertical groove on the inner side of the outer cylinder part, the inward convex side pressing transverse rib on the inner side of the outer cylinder part is embedded into the inward concave side pressing transverse groove on the outer side of the outer spiral part, so that the outer cylinder part and the outer spiral part are not mutually decomposed when horizontally rotating, and the number of screw thread turns on the inner screw thread of the outer spiral part and the screw thread rod is more than 1.
The middle beam device of the cosmetic container has a simple product production structure, does not need to increase the number of parts and does not increase the cost. The number of the thread turns of the thread structure on each part is more, the contact area between the threads is increased, and the shaking feeling and the rotation abnormal sound of the cosmetic container during rotation use are reduced. The elastic structure at the bottom of the middle dish part rubs with the inner surface of the outer spiral part, so that the position of the part can be corrected, and when the threaded parts are mutually matched, the shaking feeling and abnormal sound generated by the gaps between the threads of the threaded parts are eliminated, so that the lifting of the threaded parts is stable, and the hand feeling is smooth. The invention improves the texture and the high-grade feel of the cosmetics.
