Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION The present application claims priority under 35 U.S.C. § 119 (a) to Korean patent application number 10-2023-0051690 filed on Apr. 20, 2023 and Korean patent application number 10-2023-0089920 filed on Jul. 11, 2023, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated by reference herein. BACKGROUND OF THE INVENTION 1. Field The present invention relates to a cosmetic vessel, and more specifically, to a cosmetic vessel including a structure capable of minimizing residual pressure when discharging the contents by increasing the pressure inside the vessel by rotating a dial. 2. Description of the Related Art People generally have a desire to make themselves beautiful through makeup. Therefore, people feel satisfied by making up their skin as well as lips, nails, hair, and others in various ways. In the case of lips, makeup that makes the lips stand out from the face or dissolves dead skin cells in the lips and makes the lips smooth and plump is widely used. At this time, people use lip masks, lipstick, lip gloss, lip balm, lip tint, or the like to make up the lips. At this time, lip masks or the like not only make the lips look beautiful, but also prevent them from drying out and cracking, and have an effect of making the lips smooth and plump. Lip masks may be used on the lips depending on the type of vessel used, but depending on the type of formulation, they may be gripped by a body portion and then directly applied or may be applied by using the hands or other tools. Lip masks are produced in various shapes, including tubes. Recently, when the lip mask is in the form of a tube, a dial is rotated to increase the pressure inside the vessel and discharge the cosmetics accommodated therein. However, in the case of existing lip masks in the shape of tubes, when the cosmetics have high viscosity or hardness, there is an inconvenience in use that even after turning the dial, some of the cosmetics come out due to the residual pressure. SUMMARY OF THE INVENTION The present invention was created to solve the problem of the prior arts described above. The purpose of the present disclosure is to provide a cosmetic vessel that is capable of minimizing the internal residual pressure of a vessel body when discharging the contents by increasing the internal pressure of the vessel body by rotating a dial. A cosmetic vessel according to one aspect of the present invention includes: a vessel portion for accommodating contents in a vessel body of which upper portion is sealed by an upper cover portion and which is provided with a discharge port at an upper portion; a lower cover portion sealing an open lower portion of the vessel body; a pressurizing portion pressurizing an interior of the vessel body to discharge the contents; and an auxiliary portion elevating and lowering the pressurizing portion by rotation, wherein in the pressurizing portion, an upward movement and a downward movement may occur alternately and repeatedly while the pressurizing portion pressurizes an interior of the vessel body by being elevated by the auxiliary portion to discharge the contents. Specifically, the pressurizing portion may increase the internal pressure of the vessel body by an upward movement to discharge the contents and may dissipate a residual pressure remaining in the vessel body through an downward movement. Specifically, the pressurizing portion may include a head portion that is elevated and lowered in close contact with an inner circumferential surface of the vessel body; and a pressurizing structure portion that is coupled to the auxiliary portion at a lower portion of the head portion and that causes the head portion to repeatedly undergo an upward movement and a downward movement alternately while the head portion is elevated and lowered. Specifically, the head portion may be provided with a plurality of second guide protrusions on an outer circumferential surface, and the pressurizing structure portion may include: a first annular member being connected to the head portion, having a diameter smaller than the diameter of the head portion, and having a lower surface forming a first wave shape; a second first annular member being connected to the first annular member and having a diameter smaller than the diameter of the first annular member; and a third annular member being connected to the second annular member, having a diameter equal to the diameter of the first annular member, and having an upper surface forming a second wave shape, wherein the pressurizing structure portion forms a pressurizing guideline causing the head portion to undergo an upward movement and a downward movement alternately and repeatedly while the head portion is elevated and lowered by the first annular member, the second first annular member, and the third annular member. Specifically, each of the first wave shape and the second wave shape may be a sine wave shape
