[0002] Various types of cosmetics are on the market, and in order to safely contain these cosmetics and make them more user-friendly, various forms of cosmetic containers have emerged.

[0003] Among such cosmetic containers, above all, the airtightness and sealing performance of the cosmetic container are important. This is because if it is not stably sealed, there is a possibility that the contents contained in the container may dry out, solidify, crack, the dosage form may change, or its efficacy may decrease.

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to provide a container for contents devised to solve the above problems.

[0005] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description.

Means for Solving the Problems

[0006] A container for contents according to an embodiment of the present invention is provided. The container for contents includes Contents a container part in which a storage part for storing [contents] is formed, a fixing part that is coupled along the periphery of the container part and Contents prevents the detachment of [contents], a lid part that is rotatably coupled to the container part and opens and closes the container part, and may include [others]. The container portion is made of a relatively softer material than the lid portion, and the lid portion is made of a relatively harder material than the container portion. The container section includes an inner wall (120) surrounding the storage section, an outer wall (130) spaced outward from the inner wall, and a bottom section (140) supporting the inner wall and the outer wall. The space between the inner wall and the outer wall is open upwards, with a fixed part attached to the inner wall and a cover part attached to the outer wall. The outer wall has a sealing groove (180) on the inner circumferential surface of the end opposite to the bottom that is recessed radially outward and extends circumferentially. The lid portion has a lid body (310) and a sealing projection (340) formed integrally with the lid body from the same material as the lid body, extending downward from the lid body. When the lid closes the container, the sealing projection engages with the sealing groove between the outer wall and the fixing part. [Effects of the Invention]

[0007] According to the present invention, by forming a hook portion on the lid portion so that the lid portion can rotate relative to the container portion, and then forming a pivot axis on the container portion and connecting them, assembly is made easier, and by not using a metal hinge pin, the hassle of removing the hinge pin when disposing of the container for recycling is eliminated.

[0008] Furthermore, according to the present invention, when the lid closes the container, the sealing effect can be improved by a surface-to-surface sealing in which the sealing protrusions provided along the perimeter of the lid come into close contact with the container.

[0009] Furthermore, according to the present invention, by forming a first air groove in the container portion, the internal pressure of the container portion is relieved when the lid portion is closed, and even when the lid portion is closed, the oil content is sealed in and moisture is discharged to the outside, thereby preventing the container from swelling. In particular, even if the container portion is made of a soft material, the first air groove can prevent the shape of the container from deforming.

[0010] Furthermore, according to the present invention, since the lid is made of a hard material and the container is made of a soft material, the lid can be closed smoothly, which not only improves the user experience but also improves the sealing performance.

[0011] Furthermore, according to the present invention, by forming a second air groove, when the fixing part on which the sealing sheet is provided is joined to the container part, the internal pressure of the container part is relieved, thereby preventing the sealing sheet from bulging outwards or separating from the fixing part.

[0026] Figure 1 is a perspective view of a contents container according to an embodiment of the present invention, Figure 2 is an exploded perspective view of a contents container according to an embodiment of the present invention, Figure 3 is an exploded cross-sectional view of a contents container according to an embodiment of the present invention, and Figure 4 is a cross-sectional view of a contents container according to an embodiment of the present invention.

[0027] Referring to Figures 1 to 4, the contents container 1000 may include a container portion 100, a fixing portion 200, and a lid portion 300.

[0028] The container portion 100 may have a storage portion 110 in which the contents are contained. Here, the contents may be liquid, gel, or powder cosmetics. For example, the contents may include lotions, milk lotions, moisturizing lotions, nourishing lotions, skin lotions, skin softeners, skin toners, astringents, massage creams, nourishing creams, moisturizing creams, whitening essences, tone-up creams, sunscreens (UV blockers), sunscreen creams (sun creams), sunscreen milks (sun milks), BB creams, makeup bases (bases), foundations, CC creams, concealers, blushes, shading products, eyeshadows, eyebrow products, eye creams, primers, etc. However, the present invention is not limited to these, and various contents requiring airtight sealing, such as other dosage forms and types of cosmetics, pharmaceuticals, foods, and various compounds and compositions, can be applied. Depending on the example, the contents may be directly filled into the storage portion 110, or they may be filled into the storage portion 110 via an impregnation member, a dish, or the like.

[0029] In this embodiment, the container portion 100 may further include an inner wall 120 surrounding the storage portion 110, an outer wall 130 spaced outward from the inner wall 120, and a bottom portion 140 supporting the inner wall 120 and the outer wall 130. Here, the space between the inner wall 120 and the outer wall 130 may be open upward and sealed downward by the bottom portion 140. Furthermore, a fixing portion 200 may be connected to the inner wall 120, and a lid portion 300 may be connected to the outer wall 130 while sealing the storage portion 110. For this purpose, projections and / or grooves for sealing connections may be formed on the inner wall 120 and / or the outer wall 130.

[0030] In this embodiment, the open upper portions of the inner wall 120 and the outer wall 130 can be sealed by the fixing portion 200 and the lid portion 300. As a result, the fixing portion 200 (especially the outer edge portion 212) and the lid portion 300 (especially the sealing projection 340) can be in close contact with each other.

[0031] In this embodiment, the outer wall 130 may be formed higher than the inner wall 120. This is to prevent interference between the fixing portion 200 that connects to the inner wall 120 and the cover portion 300 that connects to the outer wall 130.

[0032] In this embodiment, the container portion 100 may further include a rotating shaft 150 and a support portion 160. The rotating shaft 150 is formed on the outside of the container portion 100 (particularly the outer wall 130), and the hook portion 320 of the lid portion 300 is connected to it, allowing the lid portion 300 to rotate. The support portion 160 may connect the rotating shaft 150 and the container portion 100 (particularly the outer wall 130).

[0033] In this embodiment, the support portion 160 extends outward from the outer wall 130 (particularly horizontally), but may be formed to bend upward in at least one region. The outward extension and upward bending allow the rotation axis 150 to be spaced horizontally and vertically away from the outer wall 130, thereby ensuring sufficient space for the rotation of the lid portion 300.

[0034] In this embodiment, the outer wall 130 may have at least one first air groove 170 formed along its periphery. When the lid 300 is closed and the container 100 is sealed, the air inside the container 100 is discharged to the outside through the first air groove 170, thereby relieving the pressure inside the container 100.

[0035] In this embodiment, the outer wall 130 may have at least one sealing groove 180 formed along its periphery. When the lid 300 seals the container 100, the sealing projection 340 of the lid 300 can be inserted into the sealing groove 180. The sealing projection 340 and the sealing groove 180 can adhere tightly along the periphery of the outer wall 130 to maintain a tight seal.

[0036] In the embodiment, the first air groove 170 may be formed on the upper side of the sealing groove 180. For example, the first air groove 170 may be formed spaced apart on the upper side of the sealing groove 180, or at least one region of the sealing groove 180 may extend upward. This effectively relieves the air compression (i.e., internal pressure) inside the container portion 100 when sealing, allowing the lid portion 300 to easily and stably seal the container portion 100.

[0037] The fixing portion 200 is joined along the perimeter of the container portion 100 (particularly the inner wall 120), preventing the impregnation member from detaching.

[0038] In the embodiment, the fixing portion 200 may include an edge portion 210 and a locking portion 220. The edge portion 210 is formed along the periphery of the container portion 100 and can be coupled to the container portion 100, and the locking portion 220 is formed to protrude inward from the upper end of the edge portion 210 and can prevent the impregnating member from detaching.

[0039] In the embodiment, the edge portion 210 may include an outer edge portion 212 and an inner edge portion 214. The inner wall 120 is inserted into the space between the outer edge portion 212 and the inner edge portion 214, and in particular, the outer edge portion 212 can be in close contact with the outside of the inner wall 120, and the inner edge portion 214 can be in close contact with the inside of the inner wall 120. In particular, the inner edge portion 214 and / or the locking portion 220 can prevent the impregnating member from detaching by pressurizing or supporting at least one area of ​​the impregnating member in the housing portion 110.

[0040] In some embodiments, the fixing portion 200 may further include at least one second air groove 230 along its periphery. The fixing portion 200 may also include a sealing sheet, in which case, when the fixing portion 200 is coupled to the container portion 100, air inside the container portion 100 is discharged through the second air groove 230, relieving the pressure inside the container portion 100 and preventing deformation of the sealing sheet. For example, the second air groove 230 may be formed on the edge portion 210, particularly on the outer edge portion 212, but is not limited thereto.

[0041] The lid portion 300 is rotatably connected to the container portion 100, allowing the container portion 100 to be opened and closed. Specifically, the lid portion 300 may include at least one of the following: the lid body 310, the hook portion 320, the shielding portion 330, the sealing projection 340, and the handle portion 350.

[0042] In the embodiment, the lid body 310 can open or close the container portion 100 by rotation, and can provide a space into which a hook portion 320, a shielding portion 330, etc., are formed and connected. According to the embodiment, at least one area of ​​the upper surface of the lid body 310 may be formed in a concave shape to form a storage space. The storage space can accommodate contents, application members (e.g., puffs, brushes, etc.). The contents stored in the lid body 310 may be the same as or different from the contents stored in the container portion 100.

[0043] In this embodiment, the hook portion 320 is a hook-shaped member formed on the outside of the lid portion 300 (particularly the lid body 310), with one outer region open. The hook portion 320 is coupled to the rotation axis 150 of the container portion 100, allowing the lid portion 300 to rotate relative to the container portion 100.

[0044] In the embodiment, the shielding portion 330 may extend to the outside of the lid portion 300 (particularly the lid body 310), and at least a part of it may have a flat plate shape. In this case, the hook portion 320 may extend from the bottom surface of the shielding portion 330. In particular, the hook portion 320 located at the lower end of the shielding portion 330 may have a size that can shield the hook portion 320 located below the shielding portion 330, the rotating shaft 150 of the container portion 100, etc., so that the hook portion 320 located below the shielding portion 330 is not exposed to the outside, and contamination such as foreign matter getting stuck in the hook portion 320, the rotating shaft 150, etc. can be prevented.

[0045] In this embodiment, the sealing projection 340 may be arranged along the periphery of the lid portion 300 (particularly the lid body 310), or it may extend downward. When the lid portion 300 closes the container portion 100, it can tightly seal the container portion 100 (particularly the outer wall 130) by making close contact with it.

[0046] In this embodiment, the handle portion 350 is for the user to grip and may be formed to protrude outward from the lid portion 300 (particularly the lid body 310). The user can easily open and close the container portion 100 by gripping the handle portion 350 and rotating the lid portion 300. It is preferable, but not limited to, that the handle portion 350 be formed on the opposite side of the hook portion 320 so that the lid portion 300 can rotate easily.

[0047] In the embodiment, the container portion 100 and the lid portion 300 may be made of different materials. In particular, the material of the container portion 100 may be relatively softer than the material of the lid portion 300, and the material of the lid portion 300 may be relatively harder than the material of the container portion 100.

[0048] In the embodiment, the material of the container portion 100 and / or the lid portion 300 may include at least one of polypropylene (PP) resin, polyethylene (PE) resin, thermoplastic elastomer (TPE) resin, and thermoplastic rubber (TPR) resin, but the material of the container portion 100 may be relatively softer than the material of the lid portion 300, and the material of the lid portion 300 may be relatively harder than the material of the container portion 100.

[0049] In the embodiment, the material of the container portion 100 may be relatively softer than the material of the lid portion 300, and the material of the lid portion 300 may be relatively harder than the material of the container portion 100. For this reason, the material of the lid portion 300 may include a polypropylene-based resin, and the material of the container portion 100 may include a polyethylene-based resin.

[0050] For example, polyethylene (PE) resins include low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), ultra-high molecular weight polyethylene (UHMWPE), cross-linked polyethylene (XLPE), chlorinated polyethylene (CPE), and combinations thereof. Polypropylene (PP) resins include homopropylene (HOMO PP), block polypropylene (BLOCK PP), random polypropylene (RANDOM PP), terpolymer polypropylene (TER PP), and combinations thereof. However, the list is not limited to these.

[0051] In the embodiment, the material of the container portion 100 may include at least two of low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE). For example, the material of the container portion 100 may include linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE). For example, the material of the container portion 100 may include 1.5 to 4 parts by weight of polyethylene (LLDPE) and 7 to 8 parts by weight of high-density polyethylene (HDPE). In this case, a moderate balance of softness and hardness can be achieved to improve usability and sealing performance. On the other hand, the material of the lid portion 300 is harder than that of the container portion 100 and may include a polypropylene (PP)-based resin. However, it is not limited to this.

[0052] In the embodiment, the contents container 1000 may further include an impregnation member. The impregnation member may be placed inside the container portion 100 (particularly the containment portion 110) and impregnated with the contents. For this purpose, the impregnation member may be made of a porous material, and the contents may be impregnated into the impregnation space formed inside, but when force is applied from the outside, the impregnated contents can be discharged.

[0053] In the embodiment, the contents container 1000 may further include a sealing sheet (not shown). The sealing sheet is for sealing the contents contained in the container portion 100 and can be coupled to the fixing portion 200 to shield the open area of ​​the fixing portion 200. For example, the sealing sheet may be made of paper, film, etc., and in particular, an adhesive may be applied along its periphery and it may be coupled to the fixing portion 200, in particular to the upper end surface of the locking portion 220. The sealing sheet may be removed for use of the contents.

[0054] The contents container 1000 shown in Figures 1 to 4 is illustrative, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0055] Figure 5 is a perspective view of a double-walled container according to an embodiment of the present invention, and Figure 6 is an exploded view of a double-walled container according to an embodiment of the present invention.

[0056] Referring to Figures 5 and 6, the double-walled container 2000 may include a contents container 1000, an outer container portion 2100, and an outer lid portion 2200.

[0057] The outer container portion 2100 has an internal storage space that can accommodate the container portion 100 of the contents container 1000. For this reason, the storage space of the outer container portion 2100 may have a shape that corresponds to the outer shape of the container portion 100, and may have fixing protrusions and / or grooves for connecting with the container portion 100.

[0058] In the embodiment, if the container portion 100 of the contents container 1000 is made of a soft material, the container portion 100 is housed within the relatively hard outer container portion 2100, thereby preventing deformation of the container portion 100 and shaking.

[0059] In this embodiment, the upper end surface of the outer container portion 2100 may be formed in a concave shape in at least a portion of it. The hook portion 320, shielding portion 330, rotating shaft 150, and support portion 160 of the contents container 1000 may be arranged in the concave region. In particular, the upper end surface of the outer container portion 2100 adjacent to the concave region is flat, and the shielding portion 330, which has a flat plate shape, is positioned continuously with the flat upper end surface.

[0060] The outer lid portion 2200 is rotatably connected to the outer container portion 2100, thereby allowing the outer container portion 2100 to be opened and closed. That is, the container portion 100 of the contents container 1000 can be primarily sealed by the lid portion 300 and secondarily sealed by the outer lid portion 2200.

[0061] For example, the outer lid portion 2200 may be connected to one side of the outer container portion 2100 by a hinge, and the outer lid portion 2200 may open and close the outer container portion 2100 by rotating the hinge.

[0062] Furthermore, the outer container portion 2100 and the outer lid portion 2200 may have locking parts formed at corresponding positions to maintain the airtight state of the outer lid portion 2200.

[0063] The double-walled container 2000 shown in Figures 5 and 6 is illustrative and represents an embodiment to which the present invention is applied, but is not limited thereto, and various configurations can be applied depending on the embodiment of the present invention.

[0064] The present invention will be described in more detail below with reference to examples and experimental examples. However, the following examples and experimental examples are illustrative of the present invention, and the content of the present invention is not limited to the following examples and experimental examples.

[0065] The contents container was manufactured using the materials for the container and lid shown in Table 1 below. In Example 1, the lid material contains polypropylene, and the container material contains polyethylene. In Comparative Example 1, both the lid and container material contain polypropylene. In Comparative Examples 2 and 3, the lid material contains polyethylene, and the container material contains polyethylene and polypropylene, respectively.

[0066] [Table 1]

[0067] In the case of Example 1, the lid can be made to close the container smoothly, and in particular, the container and lid can be tightly sealed together, improving the airtightness.

[0068] In contrast, in Comparative Example 1, both the lid and the container were rigid, causing the lid to be stiff when opening and closing the container, significantly reducing the user experience. In particular, the lid and container did not easily seal tightly when the lid was closed, resulting in reduced airtightness.

[0069] In Comparative Example 2, since both the lid and the container were made of soft material, the lid could be opened and closed smoothly. However, this also meant that both the lid and the container were prone to deformation, resulting in the lid not closing properly and instead bending.

[0070] In Comparative Example 3, the lid was made of a soft material and the container part was made of a hard material. As a result, the lid could be opened and closed smoothly, but its shape was easily deformed. On the other hand, because the container part was made of a hard material, there was a problem in that the lid did not close properly, and even when closed, it did not seal tightly.

[0071] As described above, the most suitable embodiments have been disclosed in the drawings and specification. Certain terms have been used here solely for the purpose of illustrating the invention and not to limit its meaning or the scope of the invention as defined in the claims. Therefore, a person with ordinary skill in the art should understand that various modifications and equivalent other embodiments are possible. Thus, the true technical scope of protection of the invention should be determined by the technical concept of the claims. [Explanation of Symbols]
