Description

[Technical Field]

[0001] This invention relates to containers for cosmetics, and more particularly to a color cosmetic container having a gas-sealed structure. [Previous Technology]

[0002] Chinese Utility Model Patent No. 220694614 discloses a box body connected to a lid via a hinge. A lid is placed inside the top of the box body and receives a powder puff. Two connecting rods stand on either side of the top of the box body. Two locking strips are fixed above the corresponding connecting rods. Two sliding grooves form both sides of the lid. When the connecting rod passes through the sliding groove, the lid rotates relative to the box body to an angle, causing the locking strips to partially cover the lid and prevent it from leaving the box body. Two limiting blocks protrude from both sides of the lid's covering surface. When the lid covers the box body, the limiting blocks enter the corresponding sliding grooves and are parallel to the connecting rods, providing a stable and limiting effect on the lid. Two magnetic pieces respectively fix the box body and the lid together, and the two magnetic pieces are magnetically attracted together, preventing the lid from separating from the box body.

[0003] The magnetic strips are in face-to-face contact, which best demonstrates the power of the magnetic attraction. Usually, the magnetic strips protrude from the surface of the lid or the box body. Thus, the lid covers the box body, with a gap between them, allowing air to flow into the lid. Moisture in the air comes into contact with the cosmetic powder contained in the box body through the opening of the lid, and the cosmetic powder will be affected by moisture. [Summary of the Invention]

[0004] In view of this, the inventor of this case provides a new cosmetic container, the main purpose of which is to adopt a gas-sealed structure to reduce the amount of air passing through the container and reduce the probability of moisture absorption.

[0005] To achieve the above-mentioned objectives, the cosmetic container of the present invention includes: a lid, a base, an upper chamber, and a gas-tight structure. The base is connected to the lid, and the lid covers the base and can be lifted. The upper chamber has an opening, and when the lid covers the base, the upper chamber is located within the base. The gas-tight structure includes: a gasket and a pressing portion. The gasket is connected to the opening of the upper chamber. The pressing portion raises the lid, and when the lid covers the base, the pressing portion contacts the gasket, reducing the airflow through the container and lowering the probability of moisture absorption.

[0006] In a preferred embodiment, a conical surface of the pressing portion contacts a convex surface of the gasket.

[0007] In a preferred embodiment, the gasket is adhered to the opening of the upper chamber.

[0008] In a preferred embodiment, the gasket is integrated with the opening of the upper chamber.

[0009] In order to make the objectives, features and advantages of the present invention readily apparent, one or more preferred embodiments are described in detail below with reference to the accompanying drawings.

Implementation Method

[0010] Next, embodiments of this case will be described with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar structures or units. It is foreseeable that the embodiments described are only some examples of this case, and not all of the embodiments. Other embodiments can be deduced based on the examples, or the construction can be modified or changed as needed, all of which fall within the scope of protection of this case.

[0011] In the following description, directional terms such as "up," "down," "left," "right," "front," "rear," "inner," "outer," and "side" are used only with reference to the directions in the accompanying drawings. The use of directional terms is for the purpose of better and clearer description and understanding of this case, and does not imply that the described device or element must have a specific orientation, structure, or operation, and therefore should not be construed as a limitation on the technical content of this case.

[0012] Unless specifically and explicitly specified and limited, in the following description, "installed," "connected," "attached," or "on" should be interpreted broadly, such as fixed connection, detachable connection, integral connection, mechanical connection, direct connection, indirect connection, or connection between two components. Those skilled in the art will understand the meaning of these terms in various embodiments, and even in the specific context, based on ordinary knowledge or experience.

[0013] Unless otherwise stated, in the following description, "multiple" means two or more.

[0014] In Figure 1, a preferred embodiment of the present invention is shown, a container 10 comprising: a lid 11, an inner box 20 and a base 30.

[0015] The inner side of the cover 11 has a raised pressing portion 12. A connecting portion 14 protrudes from the edge of the cover 11 at the junction with the pressing portion 12. A mirror 13 is inlaid in the pressing portion 12, exactly in the center of the inner side of the cover 11. A hole 15 passes through both sides of the connecting portion 14.

[0016] The base 30 is recessed into a lower chamber 31. The base 30 forms a joint 32 around the wall surrounding the lower chamber 31. A notch 33 is recessed in the middle of the joint 32. The notch 33 divides the joint 32 into a right half and a left half. The lower chamber 31 is connected to the outside of the base 30 through the notch 33.

[0017] When the notch 33 receives the connecting part 14, a shaft 34 passes through the left half of the connecting part 32, through the hole 15 of the connecting part 14, and into the right half of the connecting part 32, so that the cover 11 and the base 30 maintain a hinged relationship (see Figure 3). The shaft 34 supports the cover 11 and the base 30 to rotate relative to each other.

[0018] The top of the inner box 20 has a gasket 22 surrounding an upper chamber 21 of the inner box 20. Two connecting pieces 23 protrude from the outer periphery of the inner box 20. The two connecting pieces 23 are separated by a distance greater than the length of the hole 15.

[0019] During assembly, the two connecting pieces 23 span across both sides of the joint 32 and are inserted into the notch 33. The connecting piece 23 is located between the connecting part 14 and the left (or right) half of the joint 32. The shaft 34 passes through the connecting piece 23 and supports the inner box 20 to swing back and forth between the cover 11 and the base 30 (see Figure 3).

[0020] As shown in Figure 2, the lid 11 hinges the inner box 20 and the base 30, together forming the container 10. The lid 11 is opened to a larger angle relative to the base 30. The inner box 20 is opened to a smaller angle relative to the base 30, so the inner box 20 is between the lid 11 and the base 30.

[0021] In Figure 3, the top of the upper compartment 21 is an opening (not labeled), and its bottom is closed. Therefore, the upper compartment 21 of the inner box 20 can hold cosmetic powder (not shown).

[0022] In terms of material properties, the inner box 20 is harder than the gasket 22, and the gasket 22 is softer than the inner box 20. Secondly, the base of the gasket 22 fits into the opening of the upper chamber 21, and the tip of the gasket 22 expands outwards, so that the gasket 22 forms a convex curved surface (not labeled) from the inside to the top. In this embodiment, the base of the gasket 22 is adhered to the opening of the upper chamber 21. In some embodiments, the base of the gasket 22 and the opening of the upper chamber 21 are integrated as one unit.

[0023] Furthermore, the top of the lower compartment 31 is open, while its bottom is closed. Thus, a powder puff (not shown) can be inserted into the lower compartment 31 through the gap between the inner box 20 and the base 30. In other words, the powder puff can also be removed through the gap between the inner box 20 and the base 30.

[0024] As shown in Figure 4, the lid 11 covers the base 30 and stores the inner box 20 inside the container 10. As for the base 30 locking the inner box 20 and the inner box 20 locking the lid 11, these are outside the scope of this invention, so the locking structure will not be described in detail.

[0025] As can be easily understood from Figure 5, during storage, the inner box 20 partially enters the lower compartment 31, sealing the powder puff within the base 30. When the lid 11 covers the base 30, the pressing part 12 contacts the gasket 22. The convex surface of the gasket 22 resists a conical surface (not labeled) on the outer side of the pressing part 12, reducing the airflow into the upper compartment 21. Therefore, the pressing part 12 (the conical surface) and the gasket 22 (the convex surface) form a gas-tight structure, reducing the chance of moisture absorption.

[0026] Without departing from the broad concept of this case, those skilled in the art can understand and modify the above-described embodiments. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and all modifications made in accordance with the spirit and technical scope of this case should be covered and protected by the textual content defined in the scope of the patent application.
