## Title
Cosmetics container provided with inner wall scraper

## Abstract

A cosmetic container allows all of the residual cosmetics remaining on the inner wall of the cosmetic container to be used by having the scraper within the container main body that receives the cosmetics.

## Background
TECHNICAL FIELD
The present invention generally relates to a cosmetic container having an inner wall scraper. More particularly, the present invention relates to a cosmetic container having an inner wall scraper, the cosmetic container configured such that a piped-shaped scraper is provided in a container main body that receives cosmetics therein so as to scrape and move downwardly residual cosmetics remaining on an inner wall of the container main body, or stir the residual cosmetics.
BACKGROUND ART
In general, a cosmetic container used for mascara or lip gloss has been developed to be small in size so as to be convenient to use and carry because a small amount of mascara or lip gloss is applied at a time.
As a document of related art, Korean Utility Model Registration No. 20-0394669 discloses a conventional cosmetic container, and FIG. 1 is a sectional view illustrating a configuration of the conventional cosmetic container.
Herein, as shown in FIG. 1, the conventional cosmetic container includes: a cylindrical container main body 2 for receiving cosmetics (mascara liquid or lip gloss liquid) 6; a cap 3 detachably provided at an upper portion of the container main body so as to seal the inside of the container main body 2; a rod 4 provided at a lower portion of the cap 3, with bristles 5 at an end thereof for taking up and applying the cosmetics 6; and a blade unit 7 at an upper portion of the container main body 2 for adjusting quantity of the cosmetics 6 on the bristles 5 when the bristles are taken out of the container.
The conventional cosmetic container configured as described above is used by taking the cosmetics 6 received in the container main body 2 out of the container using the bristles 5, and then the cosmetics 6 are applied on a part of a user's body.
However, the conventional cosmetic container is problematic in that it is difficult to use up all of the cosmetics 6 received in the container main body 2 because the container main body 2 is usually formed into a cylindrical shape, thereby causing the viscous cosmetics 6 to remain on the inner wall of the container main body 2.
The conventional cosmetic container is further problematic in that undesirable substances are easily mixed with the cosmetics 6 when recharging the cosmetics in the container because the residual cosmetics 6 remaining on the inner wall of the container main body 2 are solidified due to air contact as time goes by.
The conventional cosmetic container is further problematic in that it is impossible to prevent deterioration of the cosmetics 6 because the cosmetics 6, which are deposited at the bottom of the container as time goes by, are used as they are.
DISCLOSURE
Technical Problem
Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and the present invention is intended to propose a cosmetic container having an inner wall scraper, the cosmetic container being capable of: scraping and moving residual cosmetics remaining on an inner wall of a container main body receiving cosmetics therein downwardly by providing a scraper within the container main body; easily moving the residual cosmetics on the inner wall of the container main body downwardly by providing a concave slope at an edge of the scraper; stirring the cosmetics and allowing the cosmetics on the inner wall of the container main body to move downwardly with ease by providing a helical ridge on an inner circumferential surface of the scraper; improving both rotary motion and a degree of sealing by providing both a retainer and sealing ring on an outer circumferential surface of the scraper; and allowing a user to easily rotate the scraper by providing a rotating cylinder that is connected to a lower portion of the scraper.
