Description

Environmentally friendly and replaceable lipstick refill container Technical field

The present invention is a container, particularly an environmentally friendly container with replaceable lipstick cores.

Background technique

Currently, all lipsticks on the market are disposable, and the original container is discarded after the paste is used. Therefore, it is easy to cause environmental pollution and does not have the concept of environmental protection.

In view of this, the inventor developed a replaceable lipstick container to address the above shortcomings, which includes an upper cover, a lipstick core assembly, a binding member and a lower bottom. One end of the lipstick core assembly has an engaging hole axially pierced through it. , the periphery of the engagement hole extends a notch in opposite directions at the symmetrical point, and the inner wall surface of the lipstick core component is provided with a protrusion extending in a direction different from the notches, and the lower bottom is protruding with an axis column, and the axis column is The ends respectively extend a flange in opposite directions in the radial direction. These flanges are clamped on the protrusions of the lipstick core component. By rotating the lower bottom, the shaft can be separated from the lipstick core component to achieve rapid operation. Replace the lipstick core assembly with a new one.

However, its product still has shortcomings. The flanges of the shaft column are directly clamped on the convex parts. Frequent rotation can easily cause wear and tear, causing the lipstick core assembly to become loose. Therefore, the inventor has been engaged in related work for many years. Based on product manufacturing, development and design experience, and based on the above goals, detailed design and careful evaluation, a truly practical invention was finally obtained.

The outer wall surface of one end of the coupling member 30 A plurality of embedded convex portions 32 are protrudingly provided, and the embedded convex portions 32 are correspondingly engaged with the embedded recessed portions 12 of the upper cover 10. The coupling member 30 is provided with an outer ring portion at one end different from the embedded convex portions 32. 33. The outer ring portion 33 is connected to an extension column 34 outward. The extension column 34 is symmetrically provided with two limiting portions 341 on its circumference. One side of each limiting portion 341 is recessed with a retaining groove 342, and the other side corresponds to the retaining groove 342. A blocking edge 343 is formed at the position of the slot 342, and two symmetrically arranged elastic arms 35 extend from the center of the outer ring portion 33 toward the direction of the through slot 31. The elastic arms 35 are spaced at an appropriate distance from each other, so that the elastic arms 35 are Two slots 351 are formed between the arms 35. A first abutment portion 352 is recessed at the top position on the inside of each elastic arm 35, and a second abutment portion is recessed on both sides of each first abutment portion 352. 353 and a third top 354, wherein the angles formed by each first top 352, each second top 353 and each third top 354 are all right angles, and each first top 353 The opening of 352 is larger than the opening of each second top 353, and the opening of each second top 353 is larger than the opening of each third top 354, and the outside of each elastic arm 35 is connected to the first top 352. There is a flange 355, and a slope 356 is formed on the lower side of each flange 355. The slopes 356 abut against the engaging portion 24 of the lipstick core assembly 20. In addition, the coupling member 30 is close to the outer ring portion 33 The inner wall surface of one end is provided with a plurality of convex portions 36 , and the convex portions 36 are respectively engaged with the convex ribs 25 .

The embedded portions 47 are respectively engaged with the outer ring portion 33 .

Continuing to refer to Figures 5 to 9 and as shown in Figure 2, if the present invention wants to replace lipstick, the upper cover 10 is first detached from the coupling member 30, and a used lipstick 50 is installed inside the lipstick core assembly 20. Then, the base 40 is rotated to the bottom in one direction. In the embodiment of the present invention, the base 40 is rotated 45 degrees in one direction to drive each first limiting rib 44 of the base 40 to move along the corresponding limiting portion 341 and make each positioning block 46 abut against the corresponding blocking edge 343 , and the fixed block 42 at the end of the shaft column 41 is also rotated 45 degrees, so that the clamping points 43 correspond to the corresponding elastic arms 35 . The position of the slot 351 and the first top 352 allows the elastic arms 35 to reset and move the inclined surfaces 356 away from the engaging portion 24 of the lipstick core assembly 20, so that the lipstick core assembly 20 can be directly detached. The combining member 30 and the base 40 .

Referring again to Figures 10 to 14 and as shown in Figure 2, another lipstick core assembly 20 equipped with another new lipstick 60 is installed into the through slot 31 of the coupling member 30, and the lipstick core assembly is used The engaging hole 23 of 20 passes through the elastic arms 35 of the coupling member 30 and the fixed block 42 of the base 40, and the base 40 is rotated in the opposite direction to the bottom. In the embodiment of the present invention, the base 40 rotates 45 degrees in the opposite direction to drive each first limiting rib 44 of the base 40 to move along the corresponding limiting portion 341, and to allow each positioning block 46 to be locked in the corresponding slot 342, and The fixed block 42 at the end of the shaft column 41 is also rotated 45 degrees, so that the clamping points 43 are correspondingly clamped on the second top 353 and the third top 354 of each elastic arm 35, thereby allowing the The elastic arms 35 are expanded outward and the inclined surfaces 356 are pressed against the engaging portion 24 of the lipstick core assembly 20, so that the lipstick core assembly 20 can be positioned on the coupling member 30, and then the upper cover 10 can be closed on the coupling member 30. After the components 30 are combined, the replacement of another lipstick 60 is completed. Therefore, by replacing another lipstick core assembly 20 instead of discarding the entire lipstick container, the lipstick container can be reused and is more environmentally friendly.

Among them, the inclined surfaces 356 of the elastic arms 35 are against the engaging portion 24 of the lipstick core assembly 20. When the base 40 rotates, the elastic restoring force of the elastic arms 35 is used to avoid the combination. The wear between the component 30 and the lipstick core assembly 20 is increased, thereby increasing the number of replacements of the lipstick core assembly 20 and extending the service life.

In addition, as shown in FIGS. 6 to 8 in conjunction with FIGS. 2 and 10 , since the fastening points 43 are correspondingly located at the slots 351 and the first contact tops 352 of the elastic arms 35 , the The elastic arms 35 reset and move the inclined surfaces 356 away from the engaging portion 24 of the lipstick core assembly 20, and through the annular design of the engaging portion 24 of the lipstick core assembly 20, a new another The lipstick core assembly 20 can be easily installed and positioned in the through slot 31 of the coupling member 30 without being restricted by the placement angle.
