The outer wall of the inner tube component is provided with upper and lower transverse ribs protruding outward in the circumferential direction to prevent the spiral component from escaping from the upper part or the lower part. The outer tube component is fixedly connected to the spiral component via a snap-fit ​​structure. The middle dish component moves up and down in the inner tube component under the driving force of the outer tube component to drive the spiral component to rotate. The rod-shaped cosmetics storage container of the present invention can be recycled and reused as a whole without having to disassemble the container according to the different materials after the cosmetics contents are used up. In industrial production, single material production is conducive to reducing material costs and management costs.

Description

Technical Field

[0001] The present invention relates to a cosmetics storage container, and more particularly to a stick-shaped cosmetics storage container for storing stick-shaped cosmetics. Background Art

[0002] Conventional stick-shaped cosmetic storage containers include a bottom cover member, a cylindrical inner cylinder member having a cut groove formed in an axial direction on the upper portion and a spiral member having a spiral groove rotatably covering the outer periphery of the cut groove of the inner cylinder member, an outer cylinder member covering the outer periphery of the spiral member, a middle plate member movable up and down in the inner cylinder member, and a coupling pin formed on the middle plate member and cooperating with the cut groove of the inner cylinder member and the spiral groove of the spiral member.

[0003] However, in the stick-shaped cosmetic storage container of this structure, the material of the so-called internal structural parts such as the inner tube part, the spiral part, the outer tube part, and the middle dish part is mostly made of relatively cheap plastic materials.

[0004] As an environmental issue, discarded plastic materials will have an impact on the environment. When processing the original container, different materials were used, and the strength of the container was ensured by assembly methods such as pressing or bonding, which made it difficult or impossible to disassemble the metal and plastic parts when the container was recycled after use. Therefore, the recycling cost is increased. Or it cannot be separated by material and is difficult to reuse, and finally becomes industrial waste. Therefore, metal materials as materials used for cosmetic containers have been re-examined, and there is a demand for the structure of stick-shaped cosmetic storage containers that try not to use plastic materials.

[0005] If a cosmetic storage container made of metal material is used, the interference friction between the parts will be insufficient during rotation, causing the container to rotate too loosely, lacking a sense of luxury and reducing the value of the product. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a stick-shaped cosmetic storage container made of all-metal material using metal material instead of plastic material.

[0007] The technical solution adopted by the present invention is: a rod-shaped cosmetic storage container, comprising a middle dish component, an inner tube component, a spiral component and an outer tube component which are nested in sequence from the inside to the outside, an upper transverse rib and a lower transverse rib protruding outwardly in the circumferential direction are formed on the outer wall of the inner tube component to prevent the spiral component from escaping from the upper part or the lower part, the outer tube component is fixedly connected to the spiral component by a snap-fit ​​structure, and the middle dish component moves up and down in the inner tube component under the driving force of the outer tube component to drive the spiral component to rotate.

[0008] A guide groove is formed axially on the cylinder wall of the inner cylinder component, and an elastic cutting groove with an upper end opening that can facilitate the insertion of the middle dish component into the inner cylinder component is also formed axially on the cylinder wall of the inner cylinder component, and a rotational load is formed between the inner cylinder component and the spiral component through the elastic deformation of the elastic cutting groove, the upper transverse rib for preventing the spiral component from falling out is integrally formed on the outer periphery of the upper port of the inner cylinder component, and the lower transverse rib for preventing the spiral component from falling out is integrally formed on the outer periphery of the lower part of the inner cylinder component; a coupling pin is integrally formed on the outer wall of the middle dish component, which can extend out of the guide groove on the inner cylinder component and move up and down along the guide groove when the outer cylinder component drives the spiral component to rotate.

[0009] A spiral groove is formed on the cylinder wall of the spiral component, and the middle dish component is combined with the spiral component by a coupling pin integrally formed on the outer wall of the middle dish component, which passes through the guide groove axially formed on the inner cylinder component and then extends out of the spiral groove. Therefore, when the spiral component rotates, it moves up and down along the guide groove driven by the spiral groove.

[0010] The spiral component has a wall formed with a convex buckle or a concave groove for combining with the outer cylinder component, and the outer cylinder component has a wall formed with a concave groove or a convex buckle for embedding and engaging with the convex buckle or the concave groove on the spiral component.

[0011] The middle dish component, the inner cylinder component, the spiral component and the outer cylinder component are all made of metal materials.

[0012] A stick-shaped cosmetic storage container comprises a middle dish component, an inner cylinder component, a spiral component and an outer cylinder component which are nested in sequence from the inside to the outside, the upper port diameter of the inner cylinder component is larger than the bottom diameter, an upper transverse rib and a lower transverse rib are formed on the outer wall of the inner cylinder component protruding outward in the circumferential direction to prevent the spiral component from escaping from the upper part or the lower part, the outer cylinder component is fixedly connected to the spiral component by a snap-fit ​​structure, and the middle dish component moves up and down in the inner cylinder component under the driving force of the outer cylinder component to drive the spiral component to rotate.

[0013] An elastic guide groove which is wide at the top and narrow at the bottom and is open at the upper end is formed axially on the cylinder wall of the inner cylinder component, which can facilitate the insertion of the middle dish component into the inner cylinder component and is used to guide the up and down movement of the middle dish component. The elastic guide groove forms an interference friction force between the inner cylinder component and the spiral component which rotates and covers the outer side of the elastic guide groove. The upper transverse rib for preventing the spiral component from falling out is integrally formed on the outer periphery of the upper port of the inner cylinder component, and the lower transverse rib for preventing the spiral component from falling out is integrally formed on the outer periphery of the lower part of the inner cylinder component. A coupling pin which can extend out of the elastic guide groove on the inner cylinder component and move up and down along the elastic guide groove when the spiral component is driven to rotate by the outer cylinder component is integrally formed on the outer wall of the middle dish component.

[0014] A spiral groove is formed on the cylinder wall of the spiral component, and the middle dish component is combined with the spiral component by a coupling pin integrally formed on the outer wall of the middle dish component, which passes through an elastic guide groove axially formed on the inner cylinder component and then extends out of the spiral groove. Therefore, when the spiral component rotates, it moves up and down along the elastic guide groove driven by the spiral groove.

[0015] The spiral component has a wall formed with a convex buckle or a concave groove for combining with the outer cylinder component, and the outer cylinder component has a wall formed with a concave groove or a convex buckle for embedding and engaging with the convex buckle or the concave groove on the spiral component.
