Description

Technical Field

[0001] The present invention relates to a cosmetic container having a pressure adjustment function. Specifically, it relates to a cosmetic container having a pressure adjustment function that can be maintained below a predetermined pressure in a upright state where the container is standing upright, a horizontal state where the container is lying horizontally, and an inverted state where the container is standing upside down.

Background Art

[0002] Recently, as people's interest in beauty has increased, functional cosmetics containing various raw materials such as vitamins have been put on the market. Such cosmetic raw materials may generate gas by being oxidized inside the cosmetic container over time, and accordingly, the internal pressure of the cosmetic container may increase.

[0003] For example, cosmetics containing vitamin C react with oxygen, high temperature, and ultraviolet rays inside the cosmetic container to generate carbon dioxide.

[0004] Thus, as the amount of carbon dioxide generated inside the cosmetic container increases, the internal pressure of the cosmetic container increases. When the internal pressure of the cosmetic container exceeds a predetermined pressure, there is a problem that the cosmetic container bursts or is damaged. In addition, when the cosmetic container bursts or is damaged, there is a risk that the cosmetics are deteriorated or the user is injured by the damaged cosmetic container.

[0005] To solve such problems, conventionally, a valve through which carbon dioxide is discharged may be formed in the cap portion of the container.

[0006] However, the valve formed in such a conventional cap can discharge carbon dioxide to the outside in the upright state where the container is standing, but in the horizontal state where the container is lying horizontally or the inverted state where the container is inverted upside down, the content is disposed on the valve side, and there is a problem that the content leaks due to the pressure of carbon dioxide.

Modes for Carrying Out the Invention

[0022] In the following, specific embodiments of the present invention will be described in detail with reference to the drawings. In this description of the present invention, if a detailed explanation of a related known configuration or function is deemed to obscure the gist of the present invention, such detailed explanation will be omitted.

[0023] Figure 1 is a perspective view of a cosmetic container 1 having a pressure adjustment function according to one embodiment of the present invention; Figure 2 is a cross-sectional view of the cosmetic container 1 having a pressure adjustment function shown in Figure 1; Figure 3 is a perspective view of the selective shielding member 20 of the cosmetic container 1 having a pressure adjustment function shown in Figure 1; Figure 4 is an exploded perspective view of the selective shielding member 20 shown in Figure 3; Figure 5 is an enlarged view of the end of the extension 24 shown in Figure 4; Figure 6 is a conceptual diagram showing the upright state of the cosmetic container 1 having a pressure adjustment function shown in Figure 1; Figure 7 is a conceptual diagram showing the inverted state of the cosmetic container 1 having a pressure adjustment function shown in Figure 1; and Figure 8 is a conceptual diagram showing the horizontal upright state of the cosmetic container 1 having a pressure adjustment function shown in Figure 1.

[0024] Referring to Figures 1 to 8, a cosmetic container 1 having a pressure adjustment function according to one embodiment of the present invention may include a main body 10 having a storage space S1 for storing contents C that may generate gas over time, and a selective shielding member 20 that can selectively allow the gas generated from the storage space S1 to pass to the outside depending on the magnitude of the gas pressure.

[0025] The selective shielding member 20 can be formed so that the valve member 28 does not come into contact with the contents C, regardless of whether the cosmetic container 1, which has a pressure adjustment function, is in an upright, horizontal, or inverted position.

[0026] As a result, the gas generated from the contents C can be discharged to the outside of the cosmetic container 1 with pressure regulating function by passing through the valve member 28, regardless of whether the cosmetic container 1 with pressure regulating function is in an upright, horizontal, or inverted position.

[0027] The contents C can be filled into the storage space S1 such that it does not come into contact with the valve member 28, regardless of whether the cosmetic container 1, which has a pressure adjustment function, is in an upright, horizontal, or inverted position.

[0028] When a user first purchases a cosmetic container 1 with a pressure adjustment function, only a portion of the storage space S1 of the cosmetic container 1 with a pressure adjustment function may be filled with contents C. For example, the contents C may be filled to 50% or less of the volume of the storage space S1.

[0029] The main body 10 may include a neck portion 11 that forms a storage space S1 capable of accommodating contents C and has an opening from which contents C can flow out.

[0030] The main body 10 may be formed in a cylindrical shape. However, the shape of the main body 10 is not limited.

[0031] The main body 10 may include a bottom surface 12, a side surface 14 extending from the bottom surface 12, and a neck portion 11 extending from the side surface 14 and forming an opening.

[0032] The bottom surface 12 can be understood as the surface facing the direction of gravity in the upright position, and the side surface 14 can be understood as the surface facing the direction of gravity in the horizontal position. In this embodiment, with reference to Figure 6, the -z direction can be understood as the direction of gravity.

[0033] In this embodiment, the three-dimensional state can be understood as a state in which the cosmetic container 1 having a pressure adjustment function is standing upright with the bottom surface 12 of the main body 10 in contact with the outside floor (see Figure 6), the horizontal upright state can be understood as a state in which the cosmetic container 1 having a pressure adjustment function is lying on its side with the side surface 14 of the main body 10 in contact with the outside floor (see Figure 8), and the inverted state can be understood as a state in which the cosmetic container 1 having a pressure adjustment function is standing in the opposite direction to the upright state with the selective shielding member 20 in contact with the outside floor (see Figure 7).

[0034] The outer circumferential surface of the neck portion 11 may have screw threads that allow it to be screw-connected to the cap 22 of the selective shielding member 20, and an opening may be formed on the inside of the neck portion 11 through which the contents C can pass.

[0035] The main body 10 may be formed so that its length in the direction of gravity is longer than its length in the direction perpendicular to the direction of gravity.

[0036] In this embodiment, the contents C can be discharged to the outside through an opening formed in the neck portion 11 of the main body 10, and the gas generated from the contents C can be discharged to the outside through the selective shielding member 20.

[0037] The selective shielding member 20 may be provided to allow only the gas generated from the contents C to pass through, but not the contents C itself. For example, the contents C may be filled in the containment space S1 so as not to come into contact with the valve member 28 of the selective shielding member 20.

[0038] The selective shielding member 20 may include a cap 22 connected to the neck portion 11 of the main body 10; an extension portion 24 extending from the cap 22 into the containment space S1 and including a first inlet H1 at the extension end through which the gas generated from the contents C flows; a plug portion 26 formed at the end of the extension portion 24 and including a second inlet H2 communicating with the first inlet H1; and a valve member 28 formed at the end of the extension portion 24 that can selectively shield the second inlet H2 and selectively allow the first inlet H1 and the second inlet H2 to communicate.

[0039] Here, the cap 22, extension 24, and valve member 28 are formed integrally, and only the plug portion 26 may be formed as a separate component. However, the concept of the present invention is not limited to this, and the cap 22, extension 24, valve member 28, and plug portion 26 may all be formed integrally.

[0040] A threaded projection 21 that can engage with the threads formed on the neck portion 11 may be formed on the inner circumferential surface of the cap 22.

[0041] An extension hole H3 extending from the extension 24 may be formed in the central part of the cap 22.

[0042] The extension 24 may extend from the cap 22 toward the housing space S1 of the main body 10.

[0043] At least a portion of the extension 24 may be placed in the accommodation space S1. For example, more than two-thirds of the extension 24 may be placed in the accommodation space S1.

[0044] The length of the extension 24 may be provided as at least half the length of the main body 10. Here, length can be understood as the length in the direction in which the extension 24 extends (in the z-axis direction).

[0045] The extension 24 can shield the opening formed in the neck portion 11.

[0046] The extension 24 shields the opening, preventing the contents C from flowing out through the opening.

[0047] For example, the extension 24 is formed integrally with the cap 22, and when the user connects the cap 22 to the neck portion 11, the extension 24 can shield the opening formed in the neck portion 11. On the other hand, when the user separates the cap 22 from the neck portion 11, the extension 24 opens the opening formed in the neck portion 11, and the contents C can be discharged to the outside through the opening.

[0048] An extension hole H3 is formed inside the extension 24, through which gas can pass, and the extension hole H3 can be connected to a first inlet H1 formed at the end of the extension 24.

[0049] The extension 24 may include an extension hole H3 that extends from the first inlet H1 and is connected to the outside.

[0050] The extension hole H3 may start from the first inlet H1 and extend through the extension 24 to the cap 22.

[0051] The extension portion 24 may be formed with a step so that the plug portion 26 can be connected to it.

[0052] For example, the extension 24 may include a first extension 24a extending from the cap 22 and a second extension 24b extending from the first extension 24a and having a smaller cross-section than the first extension 24a.

[0053] A plug portion 26, which will be described later, is connected to the second extension portion 24b, and a valve member 28 may be formed at the end of the second extension portion 24b.

[0054] The valve member 28 elastically deforms in response to the gas pressure, allowing the gas to be selectively discharged to the outside of the containment space S1. The valve member 28 may be formed at the first inlet H1 of the extension 24. Here, the first inlet H1 can be understood as a hole formed at the end of the extension 24.

[0055] For example, the valve member 28 may include an elastic member 282 formed across the first inlet H1, and a protruding member 284 connected to one side of the elastic member 282 and projecting toward the second inlet H2 of the plug portion 26.

[0056] Here, the elastic member 282 is elastically deformable in response to the gas pressure, and the protruding member 284 can selectively shield the second inlet H2 in response to the gas pressure.

[0057] If gas is generated from the contents C of the containment space S1 and the pressure in the containment space S1 reaches a predetermined pressure or higher, the gas may push the protruding member 284 blocking the second inlet H2, causing the valve member 28 to retract.

[0058] Furthermore, when gas is discharged to the outside through the extension hole H3 of the extension 24 and the pressure in the containment space S1 falls below a predetermined pressure, the valve member 28 can move forward so that the protruding member 284 can block the second inlet H2.

[0059] Here, "retraction" can be understood as the valve member 28 moving toward the cap 22, and "advancement" can be understood as the valve member 28 moving toward the opposite side of the cap 22.

[0060] The elastic member 282 is positioned in the first inlet H1 formed at the end of the extension 24, and the first inlet H1 can be divided into multiple holes.

[0061] For example, the elastic member 282 may include a first elastic member 282a that crosses the first inlet H1 in one direction and a second elastic member 282b that crosses the first inlet H1 in the other direction.

[0062] The first elastic member 282a and the second elastic member 282b are formed overlapping each other, allowing the first inlet H1 to be divided into four holes.

[0063] The elastic member 282 is positioned at the first inlet H1 and may be made of a material that elastically deforms in response to the gas pressure. For example, the elastic member 282 may elastically deform when the gas pressure in the containment space S1 is above a predetermined pressure, and may return to its original state when the gas pressure is below the predetermined pressure.

[0064] When the elastic member 282 undergoes elastic deformation, the protruding member 284 connected to the elastic member 282 can open the second inlet H2, and when the elastic member 282 returns to its original state, the protruding member 284 can close the second inlet H2.

[0065] Furthermore, the protruding member 284 may be formed at the point where the first elastic member 282a and the second elastic member 282b intersect.

[0066] The protruding member 284 may be formed to protrude toward the second inlet H2 formed in the plug portion 26.

[0067] In this embodiment, the elastic member 282 is provided from an elastically deformable material and is exemplified as a member having a shape that crosses the first inlet H1. However, the spirit of the present invention is not limited thereto, and the elastic member 282 can be formed as a spring member.

[0068] The valve member 28 is positioned in the housing space S1 of the main body 10, but can be positioned so as not to come into contact with the contents C regardless of whether the main body 10 is in an upright, horizontal, or inverted state.

[0069] For example, the valve member 28 is formed on the second extension 24b, which is the end of the extension 24, and the second extension 24b may be located in the central part of the housing space S1.

[0070] Here, the central portion of the containment space S1 can be understood as the position that occupies the central portion of the main body 10 in the longitudinal direction (z-axis direction) and the central portion of the main body 10 in the lateral direction (x-axis direction), with respect to the main body 10.

[0071] The plug portion 26 is connected to the end of the extension portion 24 and may include a second inlet H2.

[0072] Specifically, the plug portion 26 is connected to the second extension portion 24b, which is the end of the extension portion 24, and can block a portion of the first inlet H1.

[0073] The second inlet H2 is formed with a smaller diameter than the first inlet H1 and can be selectively shielded by the protruding member 284.

[0074] The plug portion 26 may include a bottom portion 26a in which the second inlet H2 is formed, and a side portion 26b that encloses the second extension portion 24b.

[0075] The selective shielding member 20 can form a sealed state in which the containment space S1 is blocked from the outside, and a pressure-relieving state in which the containment space S1 is in communication with the outside, depending on the internal pressure of the containment space S1.

[0076] For example, if the containment space S1 is below a predetermined pressure, the protruding member 284 can block the second inlet H2 to form a sealed state, and if the pressure in the containment space S1 is above the predetermined pressure, the protruding member 284 can open the second inlet H2 to form a pressure-release state.

[0077] Here, the pressure in the containment space S1 can vary depending on the amount of gas generated from the contents C. For example, the more gas generated from the contents C increases, the greater the pressure in the containment space S1 may increase.

[0078] Furthermore, the selective shielding member 20 can selectively seal the opening of the neck portion 11 formed in the main body 10, thereby selectively discharging the contents C, and can selectively seal the first inlet H1 formed at the end of the selective shielding member 20, thereby selectively discharging gas.

[0079] Furthermore, an intermediate sealing member 50 may be placed between the cap 22 of the selective shielding member 20 and the neck portion 11 of the main body 10.

[0080] The intermediate sealing member 50 can prevent the contents C and gas from leaking between the opening of the neck portion 11 and the cap 22.

[0081] The cosmetic container 1 with pressure adjustment function of this embodiment can have an upright state (see Figure 6) in which the main body 10 is standing in the direction of gravity, a sideways upright state (see Figure 7) in which the main body 10 is lying on its side perpendicular to the direction of gravity, and an inverted state (see Figure 8) in which the main body 10 is standing in the opposite direction to the upright state.

[0082] The selective shielding member 20 may include a valve member 28 that does not come into contact with the contents C regardless of whether the main body 10 is in an upright, horizontal, or inverted position.

[0083] In this case, the problem of the contents C leaking to the outside due to gas pressure can be solved not only when the cosmetic container 1 with a pressure adjustment function is in an upright position, but also when it is in a horizontal or inverted position.

[0084] Furthermore, even if gas (for example, carbon dioxide) is generated in the containment space S1 of the main body 10 and the pressure in the containment space S1 increases, the gas can be discharged to the outside through the selective shielding member 20 in any of the upright, horizontal, or inverted states, thus preventing the main body 10 from rupturing or being damaged.

[0085] The contents C can be filled into the housing space S1 of the main body 10 in such a way that it does not come into contact with the valve member 28 formed at the end of the selective shielding member 20, regardless of whether the main body 10 is in an upright, horizontal, or inverted position.

[0086] Here, the contents C may include vitamin C, which generates carbon dioxide over time.

[0087] In this embodiment, the contents C can be discharged to the outside through an opening formed in the neck portion 11 of the main body 10. The gas can also be discharged to the outside through an extension hole H3 formed in the selective shielding member 20. At this time, the protruding member 284 of the valve member 28 and the elastic member 282 coupled thereto can rise and open the second inlet H2 only when the containment space S1 is at or above a predetermined pressure.

[0088] In this embodiment, the containment space S1 can store contents C and gas generated from contents C (e.g., carbon dioxide). At this time, contents C is stored as is in the containment space S1, and only the gas is discharged to the outside of the containment space S1, so that the pressure in the containment space S1 can be maintained below a predetermined pressure.

[0089] The following describes the process by which the pressure in the storage space S1 is adjusted by the cosmetic container 1, which has a pressure adjustment function.

[0090] The contents C can be filled in the containment space S1 so as not to come into contact with the valve member 28 of the selective shielding member 20. In other words, the contents C can be filled in the containment space S1 so as not to come into contact with the second inlet H2 and the protruding member 284.

[0091] As a result, the pressure in the storage space S1 can be controlled to be below a predetermined pressure regardless of whether the cosmetic container 1, which has a pressure adjustment function, is in an upright, horizontal, or inverted state. Here, the predetermined pressure can be controlled differently depending on the degree of elasticity of the elastic member 282.

[0092] Over time, gas may be generated from the contents C stored in the containment space S1. As a result, when the pressure in the containment space S1 gradually increases and reaches a predetermined pressure, the gas can push the protruding member 284 and open the second inlet H2. This allows the gas stored in the containment space S1 to move along the second inlet H2, the first inlet H1, and the extension hole H3 and be discharged to the outside.

[0093] Furthermore, if the gas is discharged to the outside and the pressure falls below a predetermined level, the protruding member 284 can block the second inlet H2 by the elasticity of the elastic member 282.

[0094] Through this process, the storage space S1 of the main body 10 can be maintained below a predetermined pressure in any of the upright, horizontal, or inverted states.

[0095] The above describes specific embodiments of a cosmetic container 1 having a pressure adjustment function according to an embodiment of the present invention. However, these are merely illustrative examples, and the present invention is not limited to these embodiments, but should be interpreted as encompassing the broadest scope of the fundamental ideas disclosed herein. Those skilled in the art can combine or substitute the disclosed embodiments to implement embodiments not shown herein, and this does not constitute a departure from the scope of the present invention. Furthermore, it is clear that those skilled in the art can easily modify or transform the embodiments disclosed herein, and such modifications or transformations also fall within the scope of the present invention.
