Description

Technology Field

[0001] The present invention relates to a cosmetic container, and more specifically, to a tube-shaped cosmetic container in which cosmetic contents are discharged to the outside by discharge pressure and an applicator for applying cosmetic contents is provided on one side. Background Technology

[0002] In today's modern society, driven by the rapidly diversifying trends of the times, people of all ages and genders use cosmetics as needed. In particular, women utilize a wide variety of cosmetics and cosmetic products and tools in diverse colors, and thanks to the research and development of cosmetics companies, a diverse range of high-quality cosmetic products and tools are being released into the market at an ever-increasing pace.

[0003] When classifying the aforementioned cosmetics according to their purpose of use, they are categorized into facial cleansing cosmetics used to remove sebum, waste, and pollutants from the skin surface; basic skincare products used to properly supply moisture and oil to the skin; color cosmetics used to express beautiful colors; hair cosmetics used to remove foreign substances from the hair or scalp while simultaneously protecting and nourishing the hair; and perfumes used to emit a fragrance to others by dissolving fragrances in alcohol, etc.

[0004] Meanwhile, as interest in the safety of cosmetic compositions and skin care has increased due to improved living standards, the aforementioned cosmetics are increasingly being manufactured using natural ingredients; however, because these cosmetics do not contain preservatives to minimize skin irritation, they have the disadvantage of being relatively more susceptible to spoilage compared to cosmetics made with chemical ingredients. For example, the cosmetics may become contaminated or spoiled upon use due to bacterial penetration through contact with external air or oxidation of the composition.

[0005] In addition, among the above cosmetics, containers with a simple opening and closing function have been used to store and use cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, and rinses, but there was an inconvenience in having to scoop out the cosmetics from the container with a spatula or finger and apply them to the skin or hair.

[0006] Accordingly, tube containers that dispense cosmetics to the outside through changes in internal pressure caused by container pressurization are being used.

[0007] The above-described tube container is structured such that, as a user presses the soft container inward to change the internal pressure of the container, the cosmetic contained inside the container is discharged outward through the discharge port of the nozzle. It comprises a tube body made of a soft material that holds and stores a highly viscous gel-like substance inside, a shoulder coupled to the upper part of the tube body with a discharge port formed therein, and a tube lid that opens and closes the discharge port.

[0008] However, the aforementioned conventional tube container had a problem in that the discharge port was open when the tube lid was opened, allowing external air or foreign substances to enter through the discharge port, which contaminated or deteriorated the contents contained inside the tube container. In addition, even after the external force pressing the tube container was removed, the contents continued to be discharged due to the internal pressure of the tube container, making it difficult to control the discharge amount and inconvenient to use. Furthermore, since the discharged contents had to be rubbed onto the skin with the user's hands and then washed off, there was a problem of wasting cosmetics.

[0009] To solve such problems, a tube container equipped with an applicator is disclosed in Korean Registered Patent No. 10-1511120. The above-described conventional tube container comprises: a tube body to which a tube neck is coupled, wherein the tube neck is formed with a discharge port to allow the contents to be discharged at the top; a support member coupled to the top of the tube neck and forming a passage for the contents to move upwards through the discharge port; and an applicator part comprising a first applicator coupled to the top of the support member and contacting a user's skin to apply the contents, wherein the first applicator has a hollow formed therein, and a second applicator inserted into the hollow of the first applicator, which rises due to the pressure of the contents resulting from the pressurization of the tube body and descends when the pressurization of the tube body is released.

[0010] However, the above-mentioned conventional technology had a problem in that when the tube body is laterally pressurized, the contents stored inside the tube body maintain a rapid flow rate according to the instantaneous pressure change and spread apart the first applicator and the second applicator, causing the contents to suddenly pop out in a clumped state, making it inconvenient to use.

[0011] In addition, the aforementioned conventional technology had the problem that during the process in which the contents contained in the tube body were moved by discharge pressure, they leaked between the support and the applicator, making the surrounding area messy, unsanitary, and wasting the contents.

[0012] Therefore, it became necessary to improve the discharge structure of the contents based on discharge pressure and to develop a tube container with a stable airtight structure. Prior art literature

Therefore, the terms used in this invention should be defined not merely by their names, but based on their meanings and the overall content of the invention.

[0030] In the present invention, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0031] Hereinafter, a tube-shaped cosmetic container according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0032] FIG. 1 is a perspective view of a cosmetic container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a cosmetic container according to an embodiment of the present invention viewed from above, FIG. 3 is an exploded perspective view of a cosmetic container according to an embodiment of the present invention viewed from below, FIG. 4 is a cross-sectional view of a cosmetic container according to an embodiment of the present invention, and FIG. 5 is a partial enlarged view of FIG. 4.

[0033] As described above, a tubular cosmetic container according to one embodiment of the present invention may be configured to include a tube body (10), a tube head (20), an inner cap (30), an applicator (40), and an outer cap (50).

[0035] The tube-type cosmetic container according to an embodiment of the present invention is described by dividing it according to each component as follows.

[0037] A storage space of a certain size is formed inside the above tube body (10), and a liquid or gel-like content is contained in the storage space. The above tube body (10) is a tube-type storage body that discharges the contents contained inside to the outside as its shape is deformed by applying pressure from a user, and can be formed of a thin, soft synthetic resin material so that its shape is easily deformed by applying pressure from a user.

[0038] As shown in FIG. 1, the tube body (10) is preferably streamlined in shape, with the width gradually narrowing from top to bottom, and the bottom is sealed while the top is open. Of course, the shape and material of the tube body (10) are not limited to the above, and can be formed in various shapes or materials, taking into account the type of contents stored inside, usability, or design elements.

[0039] One side of the tube body (10) is open to the part that is pressed by the user, and a tube head (20) can be connected to this open part. The tube body (10) and the tube head (20) can have different degrees of deformation through differences in material or thickness. For example, the tube body (10) can be formed with a softer material or relatively thin so that the tube body (10) is easily deformed by external force, and the tube head (20) can be formed with a harder material or relatively thick so that the tube head (20) is not easily deformed by external force and maintains its shape. At this time, the tube body (10) and the tube head (20) may be processed as a single unit or processed separately and joined together.

[0041] The above tube head (20) is coupled to one side of the tube body (10) and blocks the open part of the tube body (10), while simultaneously serving as an outlet through which cosmetic contents pass when the tube body (10) is pressurized.

[0042] As shown in FIG. 5, the tube head (20) may include a head protrusion (22) formed protruding from the center of one side and having a discharge hole (22a), and a head space (24) formed on the outside of the head protrusion (22) into which at least a part of an applicator (40) is inserted.

[0043] The head protrusion (22) is formed to extend to a certain height at the center of one side of the tube head (20), and at least one discharge hole (22a) may be provided on the side wall. The discharge hole (22a) allows cosmetic contents contained in the tube body (10) to pass through and may be connected to a head space (24) formed on the outside.

[0044] The head space (24) is a space between the upper outer wall of the tube head (20) and the head protrusion (22), and can be formed along the outer circumference of the head protrusion (22). The outer and upper parts of the head space (24) are surrounded by an applicator (40), and it becomes a discharge channel through which cosmetic contents passing through the discharge hole (22a) move. As the cosmetic contents move along the discharge channel, they spread outward from the center of the tube head (20), and the end of the applicator (40) is in close contact with the bottom surface of the head space (24), thereby stably maintaining the airtightness of the discharge channel.

[0046] The inner cap (30) is coupled to the outside of the tube head (20), and an applicator (40) is fixed to one side of the tube head (20).

[0047] As seen in FIGS. 2 and 3, the inner cap (30) may be composed of a coupling part (32) that is coupled to the tube head (20) and a connecting part (34) that extends from the coupling part (32) to the center and is connected to an applicator (40). The coupling part (32) is fixedly coupled while wrapping around the outer side of the tube head (20), and the connecting part (34) is seated on the upper surface of the tube head (20) to connect the tube head (20) and the applicator (40).

[0048] A connecting hole (34a) and a through hole (34b) may be formed in the inner cap (30). The connecting hole (34a) is a hole connecting the upper space of the tube head (20) and the internal space of the applicator (40), and is formed in the center of the connecting part (34) of the inner cap (30) so that the head protrusion (22) of the tube head (20) passes through it. The through hole (34b) is a hole into which the applicator (40) is inserted and coupled, and is formed on the outer side of the connecting hole (34a) so that at least a part of the applicator (40) passes through it. It is preferable that the connecting hole (34a) be formed as a circle with a constant diameter in the center of one side of the inner cap (30), and that the through hole (34b) be formed extending along a certain section of the circumference of the connecting hole (34a).

[0049] Meanwhile, protrusions are formed on the inner circumference of the inner cap (30) and the outer circumference of the tube head (20) respectively so as to be engaged with each other, and screw threads are formed on the outer circumference of the inner cap (30) and the inner circumference of the outer cap (50) respectively so as to be detachably engaged with each other.

[0051] The applicator (40) is coupled to one side of the inner cap (30) and dispenses cosmetic contents contained inside the tube body (10).

[0052] The above applicator (40) is a tool that applies cosmetic contents to the skin by coming into direct contact with the user's skin, has a three-dimensional shape, and can be fixed to the upper part of the tube head (20) by the inner cap (30).

[0053] As shown in FIG. 5, the applicator (40) is formed integrally with the inner cap (30), and the inner cap (30) and the applicator (40) can be molded by double injection or insert injection. In the molding process of the inner cap (30) and the applicator (40), the applicator (40) passes through the through hole (34b) of the inner cap (30) in the form of molten resin and then solidifies, and the applicator (40) is formed in the inner and outer spaces of the inner cap (30), thereby improving the productivity and durability of the tube-shaped cosmetic container.

[0054] Conventionally, a hard inner cap (30) and a soft applicator (40) were injection-molded separately and attached to each other by adhesive or forcibly joined. However, due to this joining structure, productivity was reduced during the manufacturing process, and there was a limit to maintaining the adhesive force between the inner cap (30) and the soft applicator (40). In other words, conventionally, the manufacturing cost increased because an additional attachment or assembly process was required for the inner cap (30) and the applicator (40). Furthermore, productivity was reduced because it was difficult to perform such attachment or assembly work, and the work speed decreased. Additionally, there was an inconvenience in use where the applicator (40) could easily be separated from the inner cap (30) as the joint between the applicator (40) and the inner cap (30) opened up. Accordingly, the tube-shaped cosmetic container of the present invention is formed by molding the inner cap (30) and the applicator (40) using a double injection or insert injection method, thereby simplifying the manufacturing process and increasing productivity, and ensuring that the inner cap (30) and the applicator (40) are stably attached so that durability can be continuously maintained.

[0055] The applicator (40) may be composed of an application part (42) formed in the outer space of the inner cap (30) for applying the discharged cosmetic contents to the skin, and a sealing part (44) formed in the inner space of the inner cap (30) for maintaining airtightness of the discharge path while adhering to one surface of the tube head (20).

[0056] The above-mentioned coating portion (42) is formed to have a certain volume and is exposed to the upper part of the inner cap (30), allowing cosmetic contents to be discharged on one side. The above-mentioned sealing portion (44) is fitted between the tube head (20) and the inner cap (30), and is spaced apart from the outer side of the discharge hole (22a) at a certain distance, surrounding the discharge hole (22a) and adhering to the bottom surface of the head space (24) of the tube head (20). At this time, it is preferable that the sealing portion (44) be formed with a width relatively wider than the through hole (34b) of the inner cap (30) so that the inner cap (30) and the applicator (40) are not easily separated.

[0057] Meanwhile, the above-mentioned discharge head (20) and applicator (40) are provided with a discharge channel (60) through which cosmetic contents are moved when the tube body (10) is pressurized. The discharge channel (60) may include a first discharge channel (62) formed between the tube head (20) and the applicator (40) and connected to a discharge hole (22a), and a second discharge channel (64) formed on the inner side of the applicator (40) and connected to the first discharge channel (62).

[0058] The first discharge channel (62) is a passage for moving cosmetic contents that extends from the head protrusion (22) of the tube head (20) toward the head space (24), and can connect the discharge hole (22a) of the tube head (20) with the second discharge channel (64). The first discharge channel (62) horizontally guides the direction of movement of cosmetic contents rising toward the upper center of the tube head (20) by discharge pressure, and as the cosmetic contents move through the first discharge channel (62), they spread outward from the center of the tube head (20). At this time, the inner circumference of the sealing portion (44) of the applicator (40) becomes the outer wall of the first discharge channel (62), and the end of the sealing portion (44) is elastically attached to the bottom surface of the head space (24), thereby preventing the cosmetic contents from leaking out to the outside of the tube head (20), and thereby stably maintaining the airtightness between the tube head (20) and the inner cap (30). It is preferable that the first discharge channel (62) has a width extending from the outer circumference of the head protrusion (22) of the tube head (20) to the inner circumference of the sealing portion (44) of the applicator (40) when viewed from above, and has a circular shape with the center of the tube head (20) as the axis.

[0059] The second discharge channel (64) is a passage for the movement of cosmetic contents that extends outwardly from the first discharge channel (62) through the application portion (42) of the applicator (40), and can connect the first discharge channel (62) and the discharge port (46a) of the applicator (40). The second discharge channel (64) guides the movement direction of the cosmetic contents passing through the first discharge channel (62) vertically, and as the cosmetic contents move through the second discharge channel (64), they are discharged outwardly from the applicator (40). It is preferable that the second discharge channel (64) has a constant width when viewed from above and is circular in shape with the center of the applicator (40) as an axis.

[0060] As shown in FIGS. 2 and 3, a coating surface (46) may be formed on one side of the applicator (40). The coating surface (46) is the part where the cosmetic contents are dispensed and come into direct contact with the user's skin, and is formed as a convex curved surface that becomes more convex toward the center of the applicator (40). The coating surface (46) may have a uniform curvature overall, or it may have different curvatures in parts, and a flat inclined surface and a smooth curved surface may each occupy a certain area and be formed together. Of course, the coating surface (46) is not limited to the shape described above and may be varied in many ways depending on the method of applying the cosmetic contents and the convenience of use.

[0061] A discharge port (46a) for discharging cosmetic contents contained within the tube body (10) to the outside may be formed on the coating surface (46). The discharge port (46a) is connected to the upper space of the tube head (20) through the second discharge channel (64), and it is preferable that it be formed in a circle with the center of the coating surface (46) of the applicator (40) as the axis. At this time, the discharge port (46a) has an appropriate width and diameter considering the discharge amount and discharge area of ​​the cosmetic contents. For example, if the discharge amount of cosmetic contents is to be increased or decreased, the width of the discharge port (46a) can be changed to be wider or narrower, and if the discharge area of ​​cosmetic contents is to be increased or decreased, the diameter of the discharge port (46a) can be changed to be larger or smaller. Of course, the discharge port (46a) is not limited to the shape described above and can be changed in various ways depending on the discharge amount and discharge area of ​​the cosmetic contents.

[0062] Meanwhile, the applicator (40) is formed from an elastic material for a soft touch and ease of use, and is preferably formed from one or more materials among urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber), and silicone, or from polypropylene, polyethylene, and ABS (Acrylonitrile Butadiene Styrene) materials that have elasticity, and is most preferably formed from TPE (Thermo Plastic Elastomer), which is a material intermediate between rubber and plastic that is soft and has excellent durability.

[0064] The outer cap (50) is detachably coupled to the inner cap (30) to open or protect the applicator (40) to the outside.

[0065] As shown in FIG. 4, the outer cap (50) opens and closes while covering the applicator (40), and has screw threads formed on its inner circumference so that it can be screw-coupled with the screw threads formed on the tube head (20). In the liquid contents dispensing container according to the embodiment of the present invention, the inner cap (30) and the outer cap (50) are screw-coupled to each other as an example, but are not limited thereto and may have various coupling structures such as undercut coupling, coupling of protrusions and grooves, or coupling by magnetic force.

[0066] As shown in FIG. 5, the outer cap (50) may include a first insertion space (52) into which an inner cap (30) is inserted and a second insertion space (54) into which an applicator (40) is inserted. The outer wall of the first insertion space (52) surrounds the outer side of the inner cap (30) and is coupled to the inner cap (30), and the outer wall of the second insertion space (54) surrounds the outer side of the applicator (40) and is in close contact to seal the applicator (40). It is preferable that the diameter of the first insertion space (52) be formed to be relatively larger than the diameter of the second insertion space (54), and the diameter of the second insertion space (54) be formed to be equal to or relatively smaller than the diameter of the applicator (40).

[0067] A sealing ring (56) that seals the applicator (40) together with the outer wall of the second insertion space (54) may be formed on the outer cap (50). The sealing ring (56) is formed to protrude toward the applicator (40) from the inner upper surface of the outer cap (50) and is inserted into the discharge port (46a) of the applicator (40). That is, when the inner cap (30) and the outer cap (50) are combined, the outer side of the applicator (40) is pressed against the outer wall of the second insertion space (54) of the outer cap (50), and at the same time, the discharge port (46a) is closed by the sealing ring (56), thereby further strengthening the sealing function for the applicator (40).

[0069] FIGS. 6 to 8 are drawings illustrating the use of a tube-shaped cosmetic container according to an embodiment of the present invention, and a method of using the tube-shaped cosmetic container according to an embodiment of the present invention will be explained with reference thereto.

[0070] FIG. 6 is a cross-sectional view illustrating the opening of the outer cap and the pressing of the tube body according to an embodiment of the present invention, FIG. 7 is a partial enlarged view of FIG. 6, and FIG. 8 is a perspective view illustrating the discharge of cosmetic contents onto the application surface of an applicator according to an embodiment of the present invention.

[0071] First, as shown in FIG. 6, the outer cap (50) is separated from the inner cap (30). At this time, the sealing ring (56) of the outer cap (50) comes out of the discharge port (46a) of the applicator (40), the discharge port (46a) is opened, and the coating portion (42) of the applicator (40) coupled to one side of the inner cap (30) is exposed to the outside.

[0072] Subsequently, when the side of the tube body (10) is pressed, pressure is generated inside the tube body (10), and the contents contained in the tube body (10) pass through the discharge hole (22a) of the tube head (20) by the discharge pressure and flow into the first discharge channel (62), and are continuously moved to the second discharge channel (64) and come out through the discharge port (46a) of the applicator (40) and are discharged onto the application surface (46). At this time, the cosmetic contents are diffused outward by the first discharge channel (62) and the second discharge channel (64), and as the direction of movement changes, the flow velocity is reduced and evenly dispersed across the entire discharge port (46a).

[0073] After use, the applicator (40) is covered with the outer cap (50) and combined with the inner cap (30) for storage or portability. At this time, the outer wall of the second insertion space (54) of the outer cap (50) presses against the outside of the applicator (40), and at the same time, the sealing ring (56) closes the discharge port (46a).

[0075] As described above, this description has been explained with specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art to which the invention pertains can make various modifications and variations from this description.
