Vacuum anti-pollution constant temperature quantitative cosmetic container

Abstract

This utility model discloses a vacuum-sealed, pollution-proof, temperature-controlled, and quantitative cosmetic container, belonging to the field of cosmetic container technology. It includes an outer shell containing an inner liner. An annular groove is provided on the top side of the inner wall of the outer shell, and a retaining ring is provided on the top side of the outer wall of the inner liner to engage with the annular groove. A vacuum pump is installed on the top side of the outer shell. This vacuum-sealed, pollution-proof, temperature-controlled, and quantitative cosmetic container utilizes an outer shell with an insulating material (HDPE / PP / aluminum) that buffers external temperature fluctuations, maintaining the stability of the contents' physical and chemical properties. The vacuum pump evacuates air from the inner liner through a suction tube, creating a negative pressure environment that completely isolates oxygen and microorganisms, preventing oxidation, deterioration, or secondary contamination of the contents. The aluminum inner liner, except for its ultra-thin, retractable design at the top, automatically shrinks as the solvent decreases, preventing air backflow and effectively eliminating the risk of contamination from opening traditional wide-mouth bottles.

Technical Field

[0001] This utility model relates to the field of cosmetic container technology, specifically a vacuum-sealed, pollution-proof, constant-temperature, quantitative cosmetic container. Background Technology

[0002] Cosmetic containers are the outer packaging that holds the contents of cosmetics (such as lotions, creams, foundations, lipsticks, etc.). They not only protect the product and facilitate use, but are also important carriers of brand image, product positioning, and user experience. In the field of cosmetic packaging, conventional containers (such as wide-mouth bottles, ordinary pump bottles, dropper bottles, etc.) have drawbacks such as failure to prevent contamination, inactivation of temperature-sensitive active ingredients, and uncontrollable dosage. Therefore, this application proposes a vacuum-sealed, contamination-proof, temperature-controlled, and quantitative cosmetic container to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a vacuum-insulated, temperature-controlled, quantitative cosmetic container, including an outer shell 1, which is made of HDPE, PP, or aluminum. The heat-insulating material (HDPE / PP / aluminum) of the outer shell 1 can buffer external temperature fluctuations and maintain the stability of the physical and chemical properties of the contents. A UV-coated base 6 is installed at the bottom of the outer shell 1. An inner liner 2 is provided inside the outer shell 1. The inner liner 2 is made of aluminum, and the top side of the aluminum material of the inner liner 2 is thicker to ensure connection with the vacuum pump 5. The portion of the inner liner 2 located below the retaining ring 4 is retractable and ultra-thin. The aluminum inner liner 2, except for the ultra-thin, retractable design at the top, automatically shrinks as the solvent decreases, eliminating air backflow and effectively preventing the risk of contamination from opening traditional wide-mouth bottles. Furthermore, the inner liner 2 has an internal thread 9 inside the top opening 8, which connects to the external thread on the upper side of the vacuum pump 5's suction tube. The vacuum pump 5 is connected to the top of the outer shell 1 via the thread, and it evacuates the air from the inner liner through the suction tube, creating a negative pressure environment that completely isolates oxygen and microorganisms, preventing oxidation, spoilage, or secondary contamination of the contents. The outer shell 1 has an annular groove 3 on its inner wall top side, and the inner liner... 2. A retaining ring 4 is provided on the top side of the outer wall, which engages with the annular groove 3. A vacuum pump 5 is installed on the top side of the outer shell 1, and the suction tube of the vacuum pump 5 extends into the inner liner 2 through the hole 8 at the top of the inner liner 2. By rotating the vacuum pump 5, the external thread of its suction tube is connected and tightened with the internal thread 9 in the hole 8 on the inner liner 2. The retaining ring 4 on the top of the aluminum inner liner 2 is aligned with the annular groove 3 on the inner wall of the outer shell 1 and pressed down. A "click" sound indicates that the engagement and sealing are complete. This method facilitates the replacement of the inner liner 2. By pressing the vacuum pump 5 several times, the air inside the inner liner 2 is expelled through the suction tube until the pressure is reached. The resistance increases significantly, indicating the formation of negative pressure. Two protrusions 7 are provided at the top of the inner liner 2, which facilitates the removal and placement of the inner liner 2. A scraper 10 is provided on the top side of the nozzle at the top of the vacuum pump 5, and a scale line 11 is provided on the side wall of the nozzle at the top of the vacuum pump 5. By pressing the nozzle of the vacuum pump 5 vertically downward, the output volume is controlled by the scale line 11. The scraper 10 can be used to help smooth the paste. After each use, the ultra-thin part of the inner liner 2 continues to shrink as the contents decrease, maintaining a vacuum state. After the contents of the inner liner 2 are used up, the inner liner 2 can be removed and replaced.

[0023] The operational steps for this application are as follows:

[0024] By rotating the vacuum pump 5, the external thread of its suction tube is connected and tightened with the internal thread 9 in the hole 8 of the inner liner 2. The retaining ring 4 on the top of the aluminum inner liner 2 is aligned with the annular retaining groove 3 on the inner wall of the outer shell 1 and pressed down. A "click" sound indicates that the locking and sealing is complete. This method facilitates the replacement of the inner liner 2. The two protrusions 7 at the top of the inner liner 2 make it easy to put in and take out the inner liner 2. By pressing the vacuum pump 5 several times, the air in the inner liner 2 is discharged through the suction tube until the pressing resistance increases significantly, indicating that negative pressure is formed.

[0025] The vertically downward vacuum pump 5 presses the nozzle, and the output volume is controlled by the scale line 11. The scraper 10 can be used to help smooth the paste. After each use, the ultra-thin part of the inner liner 2 continues to shrink as the contents decrease, maintaining a vacuum state. After the contents of the inner liner 2 are used up, the inner liner 2 can be removed and replaced.
