Description

Technology Field

[0001] The present invention relates to the field of cosmetic containers.

[0002] More specifically, the invention relates to a cosmetic container that protects the storage container and the cap from external impact by forming the first and second protective parts with an elastic material, and improves aesthetics and gripping ability through a ring-shaped loop. Background Technology

[0003] Cosmetic containers consist of a storage container for holding the contents and a cap that seals it, and they are susceptible to external impacts, such as drops or collisions, during portability and storage. In particular, cosmetic containers made of glass or hard plastic are vulnerable to impact, raising concerns that breakage may result in leakage of contents or safety accidents caused by container fragments.

[0004] When a cosmetic container falls sideways, the impact energy is concentrated on the outermost protruding part of the container. Conventionally, the primary method used to mitigate such impact was to increase the thickness of the container itself. However, increasing the container thickness resulted in increased product weight and cost. Furthermore, conventional protective structures struggled to effectively protect both the container body and the cap simultaneously, and there were limitations in achieving both design aesthetics and protection.

[0005] Therefore, there is an increasing need for cosmetic containers that can reliably protect the storage container and cap while simultaneously satisfying ease of use and aesthetics. The problem to be solved

[0006] The present invention aims to prevent damage to a cosmetic container and leakage of contents by effectively mitigating external impacts applied to a storage container and a cap through a first protective part and a second protective part formed of an elastic material.

[0007] The present invention aims to improve shock absorption performance through compressive deformation upon external impact by having the first protective part form a wrinkled outer surface. means of solving the problem

[0008] The present invention comprises a storage container for storing contents, a cap portion that is detachably coupled to an inlet of the storage container, a first protective portion that surrounds the side of the storage container, is formed of an elastic material, and is elastically deformed by an external impact to mitigate the impact transmitted to the storage container, and a second protective portion that covers the side and top surfaces of the cap portion, is formed of an elastic material, and is elastically deformed by an external impact to mitigate the impact transmitted to the cap portion. The first protective portion includes a first-1 protective portion having a bottom surface with a predetermined slope that exposes a part of the storage container, a first-2 protective portion disposed above the first-1 protective portion and adjacent to the cap portion, and a first-3 protective portion disposed between the first-1 protective portion and the first-2 protective portion. The second protective portion includes a second-1 protective portion adjacent to the storage container, a second-2 protective portion disposed above the second-1 protective portion and defining an opening, and at least one ring-shaped loop portion disposed in the opening, wherein the ring-shaped loop portion is in a knot shape protruding upward from the cap portion. A cosmetic container is provided that is formed such that the diameter of the first-3 protective portion is larger than the diameter of the first-1 protective portion and the diameter of the first-2 protective portion, and the diameter of the second-2 protective portion is larger than the diameter of the second-1 protective portion.

[0009] The above-mentioned ring-shaped loop portion may include a first loop portion disposed in the opening; a second loop portion disposed adjacent to the first loop portion; and a third loop portion connected to the first loop portion and the second loop portion.

[0010] The diameters of the first-1 protection part and the first-2 protection part are the same, and the diameters of the second-1 protection part and the second-2 protection part, respectively, may be larger than the diameter of the first-1 protection part.

[0011] The bottom surfaces of the first-2 and first-3 protective parts have a predetermined inclination with respect to a plane perpendicular to the central axis of the storage container, and the inclination direction of the bottom surface of the first-1 protective part may be opposite to the inclination direction of the bottom surfaces of the first-2 and first-3 protective parts.

[0013] The sum of the heights of the above 2-1 protective part and the above 2-2 protective part is about 12 mm or more and 20 mm or less, the height of the above ring-shaped loop part is about 25 mm or more and 40 mm or less, and the total height of the above 2 protective part may be about 40 mm or more and 60 mm or less.

[0014] The above-mentioned first-1 protective part, the above-mentioned first-2 protective part, and the above-mentioned first-3 protective part are formed continuously along the circumferential direction of the storage container, so as to disperse impact applied in the lateral direction of the storage container.

[0015] The above-mentioned first-1 protective part, the above-mentioned first-2 protective part, and the above-mentioned first-3 protective part are arranged adjacent to each other in the vertical direction to form a corrugated outer surface, and the corrugated outer surface can mitigate the impact transmitted to the storage container by undergoing compressive deformation upon external impact.

[0016] The above 2-1 protective part and the above 2-2 protective part are integrally formed on the outer side of the cap part, so as to disperse the impact transmitted to the side of the cap part.

[0017] The first protective part and the second protective part may be formed of an elastic material having a Shore A hardness of 20 or more and 70 or less. Effects of the invention

[0018] The present invention can effectively mitigate the impact transmitted to the storage container and the cap portion during a fall and collision by the first and second protective portions made of elastic material, thereby preventing damage and leakage of contents.

[0019] The present invention can mitigate the impact transmitted to the storage container by having the first-third protective parts contact an external object before the storage container during a side impact.

[0020] The present invention can effectively disperse the lateral impact applied to the cap by the second-2 protective part contacting an external object before the cap part during a lateral impact.

[0021] The present invention can improve shock absorption performance by having a first protective part form a wrinkled outer surface and undergo compressive deformation upon external impact.

[0022] In this invention, the third loop portion is formed in a ring shape, which can mitigate the impact transmitted to the upper side of the cap portion through elastic deformation while also improving aesthetics. Brief explanation of the drawing

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0025] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0026] FIG. 1 is a perspective view of a cosmetic container according to an embodiment of the present invention. FIG. 2 is a front view of a cosmetic container according to an embodiment of the present invention. FIG. 3 is a top view of a cosmetic container according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a cosmetic container according to an embodiment of the present invention.

[0027] Referring to FIGS. 1 to 4, a cosmetic container for preventing impact on contents according to one embodiment of the present invention may include a storage container (1), a cap portion (2), a first protective portion (3), and a second protective portion (4).

[0028] The storage container (1) is configured to provide a space for storing cosmetic contents, and may have an injection port formed on the top where a cap portion (2) is detachable and coupled. The outer surface of the storage container (1) may be surrounded and protected by a first protective portion (3).

[0029] The cap portion (2) can be separated and coupled to the opening of the storage container (1) to seal the contents. The side and top surfaces of the cap portion (2) can be covered by the second protective portion (4). The top surface (26) of the cap portion (2) can be covered and protected by the upper part of the second protective portion (4).

[0030] The first protective part (3) may be formed to surround the side of the storage container (1). The first protective part (3) may be formed of an elastic material and elastically deformed by external impact, thereby mitigating the impact transmitted to the storage container (1). The first protective part (3) may include a first-1 protective part (31), a first-2 protective part (32), and a first-3 protective part (33).

[0031] Referring to FIG. 1, the first-1 protection part (31), the first-2 protection part (32), and the first-3 protection part (33) may be arranged adjacent to each other in the vertical direction to form a corrugated outer surface. The corrugated outer surface may have a structure in which each corrugated segment undergoes sequential compressive deformation when an impact load is applied. Due to this structural characteristic, impact energy is dispersed and absorbed during the deformation process of each protection part, thereby reducing the amount of impact directly transmitted to the storage container (1).

[0032] In particular, as can be seen in FIG. 1, the slope direction of the bottom surface (315) of the first-1 protection part (31) can be formed in a direction opposite to the slope direction of the bottom surface (325) of the first-2 protection part (32) and the bottom surface (335) of the first-3 protection part (33).

[0033] Specifically, the bottom surfaces (325, 335) of the first-2 protection part (32) and the first-3 protection part (33) have a predetermined slope with respect to a plane perpendicular to the central axis of the storage container (1), and the bottom surface (315) of the first-1 protection part (31) may have a slope in the opposite direction.

[0034] As such, by forming the underside slope directions of adjacent protective parts differently, each protective part can deform in a different direction when a lateral or oblique impact is applied, and accordingly, the impact energy can be dispersed over a wider area.

[0035] In addition, this difference in slope direction can improve impact dispersion performance by allowing the outer surface of the corrugated shape to deform and recover more effectively against multi-directional impacts.

[0036] Additionally, the first-1 protective section (31), the first-2 protective section (32), and the first-3 protective section (33) are formed continuously along the circumferential direction of the storage container (1) to disperse impact applied in the lateral direction of the storage container (1).

[0037] The first-1 protective portion (31) may be formed such that its bottom surface (315) has a predetermined slope and exposes a portion of the storage container (1) to the outside. The first-2 protective portion (32) may be positioned above the first-1 protective portion (31) and adjacent to the cap portion (2). The first-3 protective portion (33) may be positioned between the first-1 protective portion (31) and the first-2 protective portion (32).

[0038] Referring to FIG. 2, the diameter (d33) of the first-3rd protective part (33) can be formed to be larger than the diameter (d31) of the first-1st protective part (31) and the diameter (d32) of the first-2nd protective part (32). Accordingly, when the cosmetic container falls in a side direction or receives a side impact, the first-3rd protective part (33), which has the largest diameter, comes into contact with an external object before the storage container (1) and bears the impact load first.

[0039] That is, the first-third protective part (33) functions as a point of contact for impact loads, and can perform the role of a buffer material that absorbs impact energy through the elastic deformation of the elastic material and transmits only the remaining impact to the storage container (1). Through this, the risk of damage can be effectively reduced by preventing the storage container (1) from directly colliding with an external object.

[0040] Meanwhile, the protruding shapes of the first protective part (3) and the second protective part (4) can change the transmission path of the impact load by contacting an external object before the storage container (1) and the cap part (2) when an external impact occurs. Accordingly, the impact energy can be dispersed and absorbed during the compression deformation, bending deformation, and restoration process of the elastic material, and the peak load directly transmitted to the storage container (1) and the cap part (2) can be reduced. In addition, since the multiple protective parts formed in a corrugated shape can provide progressive deformation characteristics that deform stepwise as the impact load increases, the impact energy can be dispersed over time to alleviate local stress concentration. Along with this, the contact area and contact time with the external object can be increased by the protruding shapes, so the impact load can be dispersed over a wider area.

[0041] For example, the diameter (d1) of the storage container (1) may be approximately 20 mm or more and 25 mm or less, and the diameter (d33) of the first-third protective part (33) may be approximately 30 mm or more and 40 mm or less. Additionally, the diameter (d33) of the first-third protective part (33) may be formed to be approximately 1.3 times or more and 2 times or less than the diameter (d1) of the storage container (1). Accordingly, the first-third protective part (33) forms a buffer area protruding outward from the storage container (1), so that it can come into contact with an external object before the storage container (1) when a side impact occurs.

[0042] This protrusion width can provide a buffer area where the first-3rd protective part (33) can elastically deform by coming into contact with an external object before the storage container (1) upon external impact. Additionally, the diameter (d31) of the first-1st protective part (31) and the diameter (d32) of the first-2nd protective part (32) can be formed to be the same as each other.

[0043] Additionally, the height (h3) of the first protective part (3) may be approximately 25 mm or more and 35 mm or less, and the height (h151) from the upper surface (326) of the first-second protective part (32) to the bottom surface (15) of the storage container (1) may be approximately 28 mm or more and 35 mm or less. These dimensional ranges can be set so as to stably cover at least a part of the side of the storage container (1) while ensuring both user gripping convenience and a sense of balance in appearance.

[0044] The second protective part (4) may be formed to cover the side and top surfaces of the cap part (2). The second protective part (4) may be formed of an elastic material and elastically deformed by external impact, thereby mitigating the impact transmitted to the cap part (2).

[0045] The second protection section (4) may include a second-1 protection section (41), a second-2 protection section (42), a first loop section (410), a second loop section (420), and a third loop section (430).

[0046] The second-1 protective portion (41) may be positioned adjacent to the storage container (1). The second-2 protective portion (42) is positioned above the second-1 protective portion (41), and an opening (421) may be defined in the center. The diameter (d42) of the second-2 protective portion (42) may be formed to be larger than the diameter (d41) of the second-1 protective portion (41).

[0047] Accordingly, when a side impact is applied to the cap part (2), the second-2 protective part (42), which has a larger diameter, comes into contact with an external object before the cap part (2) and primarily bears the impact load.

[0048] That is, just as the first-3rd protection part (33) protects the side of the storage container (1), the second-2nd protection part (42) functions as a cushioning material against side impact of the cap part (2), thereby preventing the cap part (2) from directly colliding with an external object.

[0049] Additionally, the diameters (d41, d42) of the second-1 protective part (41) and the second-2 protective part (42), respectively, may be formed to be larger than the diameter (d31) of the first-1 protective part (31). The second-1 protective part (41) and the second-2 protective part (42) are formed integrally on the outer side of the cap part (2) so as to disperse the impact transmitted to the side of the cap part (2).

[0050] Meanwhile, as mentioned above, the first protective part (3) and the second protective part (4) may be formed of an elastic material capable of absorbing and dispersing impact energy through elastic deformation upon external impact. The elastic material may include silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), rubber, or a polymer material having equivalent elastic recovery force. Since such an elastic material can be restored to its original shape after being compressed, bent, or tensile-deformed by an external impact, it can mitigate the impact load transmitted to the storage container (1) and the cap part (2). In particular, by applying a material having appropriate elasticity and rigidity, the shape stability and impact mitigation performance of the protective structure can be stably maintained even in a repetitive impact environment.

[0051] Referring to FIG. 2, the sum of the height (h41) of the 2-1 protection part (41) and the height (h42) of the 2-2 protection part (42) may be 16.1 mm. This is designed to be a height suitable for protecting the cap part (2) from side impact by covering at least a portion of the side of the cap part (2).

[0052] For example, the sum of the heights of the 2-1 protection part (41) and the 2-2 protection part (42) may be approximately 12 mm or more and 20 mm or less, and the height of the ring-shaped loop part may be approximately 25 mm or more and 40 mm or less. Additionally, the total height of the 2 protection part (4) may be approximately 40 mm or more and 60 mm or less. Accordingly, the ring-shaped loop part protrudes sufficiently upward from the cap part (2) to absorb impact energy through elastic deformation when an impact occurs on the upper side, and can form a protective space that prevents direct collision with the upper surface of the cap part (2).

[0053] Meanwhile, the first protective part (3) and the second protective part (4) can be attached to the outside of the storage container (1) and the cap part (2) in various ways. For example, the first protective part (3) and the second protective part (4) can be detachably attached to the storage container (1) and the cap part (2), and can be formed so that a user can replace or separate and clean them. In addition, the first protective part (3) and the second protective part (4) can be attached to the outer surface of the storage container (1) or the cap part (2) through at least one of insert molding, overmolding, adhesive, or mechanical fastening methods. Accordingly, various attachment structures can be applied depending on the manufacturing process, material characteristics, and product design.

[0054] Referring to FIGS. 2 and 3, the first loop portion (410), the second loop portion (420), and the third loop portion (430) may be positioned in the opening (421) defined in the second-2 protection portion (42). The second loop portion (420) may be positioned to contact the first loop portion (410). The third loop portion (430) may be formed in a ring shape and positioned to contact both the first loop portion (410) and the second loop portion (420).

[0055] The height (h430) of the third loop section (430) can be formed to be greater than the height (h410) of the first loop section (410) and the height (h420) of the second loop section (420). Accordingly, when an impact is applied to the upper side of the cap section (2), the third loop section (430) can first come into contact with an external object and absorb the impact load through elastic deformation.

[0056] In particular, since the third loop portion (430) is formed in a ring shape, when an impact load is applied, the entire ring structure undergoes elastic deformation, thereby effectively absorbing impact energy. Additionally, the third loop portion (430) is supported by contacting both the first loop portion (410) and the second loop portion (420), so that deformation caused by impact is evenly distributed throughout the ring, thereby suppressing localized stress concentration.

[0057] For example, the height (h420) of the second loop portion (420) may be 9.1 mm, and the height (h430) of the third loop portion (430) may be 33.8 mm. By forming the height (h430) of the third loop portion (430) to be approximately 3.7 times larger than the height (h420) of the second loop portion (420), the third loop portion (430) can protrude sufficiently upward from the cap portion (2) to form a protective space that prevents direct collision with the upper surface (26) of the cap portion (2). In addition, the ring shape of the third loop portion (430) can also function as an aesthetic decorative element to improve the quality of the product's exterior design.

[0058] Meanwhile, the wrinkled outer surface of the first protective part (3) and the three-dimensional shape of the loop-shaped part can improve the grip stability of the cosmetic container by allowing the user's finger to be stably supported on the outer surface. In particular, the multiple protruding shapes can increase the frictional surface area in contact with the user's hand to suppress slipping, and allow the user to grip and operate the container more stably. In addition, the knot shape protruding upward can function as a design element that improves the aesthetic appearance of the product while allowing the user to hook their finger to carry it or easily operate it during the opening and closing process.

[0059] Referring to FIG. 4, it can be seen that cosmetic contents can be stored inside the storage container (1), the outer surface of the storage container (1) is surrounded by the first protective part (3), and the outer surface of the cap part (2) is covered by the second protective part (4).

[0060] Through the cross-sectional shape, it can be seen that the first protective part (3) and the second protective part (4) are in close contact with and surround the outside of the storage container (1) and the cap part (2), and through this, the storage container (1) and the cap part (2) can be effectively protected from external impact by the first protective part (3) and the second protective part (4).

[0061] Meanwhile, the first protective part (3) and the second protective part (4) may be formed of an elastic material having a Shore A hardness of 20 or more and 70 or less. Shore A hardness is an indicator of the elastic deformation resistance characteristics of a material; the lower the hardness, the more flexible it is and the easier it is to deform, and the higher the hardness, the greater the rigidity and the better the shape retention.

[0062] If the Shore A hardness is less than 20, it is difficult to maintain the shape of the protective part and there may be insufficient rigidity to structurally support impact energy, and if it exceeds 70, there is a risk that the impact energy will be transferred directly to the storage container (1) and the cap part (2) because the elastic deformation for shock absorption is not sufficiently achieved.

[0063] Therefore, by using an elastic material within the above hardness range, appropriate stiffness and elastic recovery force are simultaneously secured, allowing for stable protection performance and shape retention characteristics even under repeated impacts.

[0064] As described above, although the present invention has been explained by limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.

[0065] Meanwhile, although terms indicating directions such as up, down, left, right, front, and back have been used in this invention, these terms are used merely for convenience of explanation, and it is obvious to those skilled in the art that they may vary depending on the position of the object or the position of the observer.
