Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a cosmetic container according to the present invention includes a container body 100 in which cosmetics are accommodated, and a cap 200 that is opened and closed with respect to an engaging portion 110 of the container body .

An airtight pad 220 made of soft material is integrally formed on the inner peripheral surface of the open end 210 of the cap 200 contacting the side wall 112 of the engaging portion 110 of the container body 100, And an internal thread 230 corresponding to a male screw 120 formed on a side wall of the coupling portion of the container body is integrally formed as an inner circumferential surface of the airtight pad.

When the cap 200 is screwed to the engaging portion 110 of the container body 100, the female thread 230 of the airtight pad 220 is tightly adhered to the male screw formed by the side wall of the engaging portion The side wall 112 of the engaging portion 110 of the container body 100 is airtight.

The airtight pad 220 according to the present invention is formed of a soft material, that is, a soft material, in order to ensure airtightness with respect to the coupling portion 110 of the container body 100, But it is preferable to use materials such as elastomer, polyurethane, silicon, and polypropylene in consideration of the injection workability and the airtightness safety due to the coupling of the cap 200 Do.

Here, it is preferable that the airtight pad 220 has a certain hardness depending on the material. For example, in the case of polyurethane, it is preferable to have a hardness of about 80 to 100. The reason why the airtight pads have a certain hardness depending on the material is that when the cap 200 is coupled to the coupling portion 112 of the container body 100, the coupling force may be weakened if it is too soft, It is desirable to have an appropriate hardness for providing adequate bonding strength and air tightness depending on the material since the air tightness can be weakened. Depending on the material, the hardness of the airtight pads may be sufficiently obtained through repeated performance testing and testing of the product.
