AI Technical Summary

Technical Problem

In the sealed state, existing filling containers may cause the lid to be lifted due to differences in internal pressure, which will cause problems such as cosmetic dryness.

Method used

A filling container is designed which includes a main storage unit and an external storage unit, and the cover ensures that the cover does not lift when it enters the second storage unit and matches the specific structure of the container body while forming part openings through the ring to prevent cosmetic spills.

Benefits of technology

Effectively prevent the lid from being lifted, ensure the sealing of the container, and prevent cosmetics from drying or spoiling due to loss of sealing.

Abstract

To provide a refill container and a cosmetic container capable of securing air tightness and suppressing floating of a lid.SOLUTION: A refill container includes: a container body 12 including a first storage part 21 and a second storage part 22; a lid 13; and a ring member 14. The lid 13 includes a first projection 23. The first projection 23 includes a first protrusion 23b protruding to the outside of the lid 13, and an extension part 23c extending downward from the first protrusion 23b. The second storage part 22 is defined by an inner wall part 12d, an outer wall part 12f located outside the inner wall part 12d in plan view, and a bottom part 12g. The outer wall part 12f includes a first contact part 22b that comes into contact with the extension part 23c from the outside in plan view when the first protrusion 23 enters the second storage part 22, and a first recess part 22c which the first protrusion 23b enters when the first protrusion 23 enters the second storage part 22.SELECTED DRAWING: Figure 4
