Description

[Technical field]

[0001] The present invention relates to a content container. [Background technology]

[0002] Container stoppers are attached to and detached from containers in various ways to open and close the containers, typically by a screw connection method in which a screw thread is formed on the outer circumferential surface of a neck formed on one side of the container and a corresponding screw thread is formed on the inner circumferential surface of the stopper.

[0003] According to such a screw fastening method, when the stopper is separated from the container, the threads on the neck are exposed to the outside. However, since the threads are formed in a standard design for every container, there is a problem that the threads can only provide a functional element to the container, and no aesthetic design can be achieved.

[0004] In addition, in the case of the screw coupling method, when the threads are aligned with each other and the user applies external force, the threads go over each other to couple together, which causes problems in that a certain amount of idling is required for the initial alignment of the threads, which requires unnecessary external force, and in order to couple completely, the user must continuously apply external force. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a content container that solves the above-mentioned problems.

[0008] Furthermore, at least one second groove that forms a non-contact area with the thread can be formed between the multiple coupling units in the second direction by the spacing in the first direction.

[0009] In addition, the cross-sectional area of ​​the coupling unit may decrease toward the protruding direction, and the contact area with the screw thread may decrease.

[0010] Additionally, the coupling unit may have at least one of a circular, elliptical, and polygonal base.

[0011] The coupling unit may have a polygonal base, the polygon having at least one side formed in the first direction, and may guide the movement of the screw thread.

[0012] The bottom surface may be rhombus-shaped with the angle of the top apex being 49.5° to 160°.

[0013] In addition, at least one entrance / exit for guiding the end of the thread into the first groove may be formed between the multiple coupling units located at the uppermost end by spacing the coupling parts apart in the circumferential direction.

[0014] In addition, the coupling portion may include at least one first fixing portion formed on an underside of the coupling unit, and the plug portion may include at least one second fixing portion formed on an underside of the thread and contacting the first fixing portion while maintaining the coupling of the plug portion.

[0015] In addition, at least one of the first fixing portion and the second fixing portion is formed in a number corresponding to the threads, and when the plug portion is coupled to the coupling portion, the first fixing portion and the second fixing portion can contact each other regardless of the initial alignment position of the plug portion.

[0016] In addition, during the process of connecting or disconnecting the plug part and the connecting part, a predetermined resistance may be generated between the first fixing part and the second fixing part as the first fixing part and the second fixing part come into contact with each other.

[0017] The plug portion may include an inner plug having the thread formed on the inside and at least one fitting protrusion formed on the outside, and an outer plug having at least one fitting groove formed on the inside corresponding to the fitting protrusion and coupled to surround the inner plug.

[0018] According to an embodiment of the present invention, there is provided a content container, the content container including a container part for accommodating a content, a plug part for opening and closing the container part and having a plurality of coupling units protrudingly formed along an inner circumferential surface, and a coupling part provided on one side of the container part and having at least one screw thread formed on an outer side in a first direction, the plurality of coupling units are spaced apart from each other in the first direction and a second direction opposite to the first direction, at least one first groove is formed between the plurality of coupling units in the first direction due to the spacing in the second direction, and the plug part can be detachably coupled to the coupling part as the screw thread moves.

Effect of the Invention

[0021] According to the present invention, by forming a plurality of connecting units at the connecting portion instead of threads for threaded connection between the container portion and the stopper portion, it is possible to break away from the typical aesthetic appearance created by threads and impart a new aesthetic appearance created by the connecting units.

[0022] In addition, according to the present invention, the frictional force is reduced compared to the traditional screw fastening method using multiple threads, so that the fastening between the stopper and the container can be performed automatically or with little external force, making it easy to use.

[0023] Furthermore, according to the present invention, the plug part and the container part can be firmly connected by the fixing part, thereby improving the sealing force.

[0024] In addition, according to the present invention, the connection between the plug part and the coupling part can be started and completed simply by positioning the plug part at the upper end of the coupling part, regardless of the initial alignment position of the plug part and the coupling part, thereby eliminating idling and external force from the user required for screw connection.

[0031] With reference to FIGS. 1 to 3, a content container 1000 may include a container portion 100, a plug portion 200, and a coupling portion 300. As shown in FIG.

[0032] The container 100 may contain contents. In this case, the contents may be liquid, gel, or powder cosmetics. For example, the contents may include lotion, milk lotion, moisture lotion, nourishing lotion, skin lotion, skin softener, skin toner, astringent, massage cream, nourishing cream, moisture cream, whitening essence, tone-up cream, sunscreen, sun cream, sun milk, BB cream, base, foundation, CC cream, concealer, blusher, shading, eyeshadow, eyebrow, eye cream, primer, etc. However, the contents are not limited to these, and other forms and types of cosmetics, medical contents, etc. may be applied.

[0033] The plug portion 200 can open and close the container portion 100. To this end, the plug portion 200 can be directly / indirectly coupled to the container portion 100 via the coupling portion 300. More specifically, the plug portion 200 can be coupled to the coupling portion 300 to seal the container portion 100, and can be separated from the coupling portion 300 to open the container portion 100 and allow the contents inside the container portion 100 to be used. For example, the plug portion 200 can include at least one screw thread 211 for coupling with the coupling portion 300 and at least one second fastening portion 212 for maintaining the coupling. However, the present invention is not limited thereto.

[0034] The connecting portion 300 is provided on one side of the container portion 100 and can be detachably connected to the plug portion 200 .

[0035] Depending on the embodiment, the coupling portion 300 may be formed in one area of ​​the container portion 100. Specifically, for example, the coupling portion 300 may be located in the neck portion of the container portion 100. However, this is merely an example, and the coupling portion 300 may be formed in various locations within the container portion 100 suitable for coupling with the stopper portion 200.

[0036] Depending on the embodiment, the coupling portion 300 may be a separate part from the container portion 100 and may be directly / indirectly coupled to the container portion 100. For example, the coupling portion 300 may be directly coupled to the container portion 100 by a threaded coupling, a male-female coupling, etc., or may be indirectly coupled to the container portion 100 via at least one other feature (e.g., a pump assembly, a shoulder portion, etc.).

[0037] In an embodiment, the coupling part 300 and the plug part 200 may be screw-coupled. To this end, the coupling part 300 may have a plurality of coupling units 310 protruding along an outer circumferential surface thereof, and the plug part 200 may have at least one thread 211 formed on the inside thereof. The thread 211 may move along the space between the plurality of coupling units 310, thereby allowing the coupling part 300 and the plug part 200 to be screw-coupled. However, this is not limited thereto, and various embodiments may be applied, such as at least one thread being formed on the outside of the coupling part 300, a plurality of coupling units being protruding along an inner circumferential surface of the plug part 200, or a plurality of coupling units being protruding on both the outer circumferential surface of the coupling part 300 and the inner circumferential surface of the plug part 200.

[0038] In an embodiment, the screw thread 211 may be formed in a first direction, and the multiple coupling units 310 may be arranged spaced apart from each other in the first direction and a second direction opposite to the first direction. Specifically, as shown in FIG. 3, the first direction may refer to a spiral direction X descending in a clockwise direction from the upper end, and the second direction may refer to a spiral direction Y descending in a counterclockwise direction from the upper end. However, the first direction and the second direction are not limited thereto, and the first direction and the second direction may be defined as opposite directions, or may be defined as various other directions.

[0039] In an embodiment, by spacing the multiple coupling units 310 apart in the second direction, at least one first groove 320 may be formed in the first direction between the multiple coupling units 310. The thread 211 may move along the first groove 320, thereby allowing the plug portion 200 to be attached to and detached from the coupling portion 300.

[0040] In an embodiment, by separating the multiple coupling units 310 in the first direction, at least one second groove 330 may be formed in the second direction between the multiple coupling units 310. Due to such second groove 330, a non-contact area with the thread 211 may be formed between the multiple coupling units 310. The non-contact area may reduce the frictional force between the thread 211 and the coupling unit 310.

[0041] In an embodiment, the cross-sectional area of ​​the coupling unit 310 may decrease in the protruding direction. Such a decrease in the cross-sectional area may decrease the contact area between the coupling unit 310 and the thread 211 in the protruding direction. The decrease in the contact area may decrease the frictional force between the thread 211 and the coupling unit 310.

[0042] In an embodiment, the frictional force between the thread 211 and the multiple coupling units 310 may be reduced, thereby reducing the external force required to couple the plug 200 and the coupling portion 300. As a result, the thread 211 may move along the first groove 320 when only a small external force is applied, or even when no external force is applied (e.g., due to gravity, etc.).

[0043] In an embodiment, the coupling unit 310 may include a bottom surface in contact with the surface of the container portion 100 and a protruding region extending outward from the bottom surface. The bottom surface may be, for example, polygonal, elliptical, or circular. Here, the polygonal bottom surface may include at least a portion, for example, at least one side or at least one vertex, being curved in addition to a straight line. Also, the protruding region may extend outward from the bottom surface, but may be formed so that the end is sharp or the cross-sectional area is reduced. Thus, the coupling unit 310 may have a shape such as, for example, a polygonal prism, a polygonal pyramid, a polygonal truncated pyramid, a hemisphere, a cylinder, a truncated cone, or a cone. However, this is merely an example, and various configurations can be applied to the shape of the coupling unit 310.

[0044] In an embodiment, the coupling unit 310 can guide the movement of the thread 211 along the first groove 320 through the bottom surface. For this purpose, the bottom surface of the coupling unit 310 can be formed with at least a portion of its circumference in the first direction. Here, forming at least a portion of its circumference in the first direction can include not only the case where the entire area of ​​at least one side of the bottom surface is formed in the first direction, but also the case where only a portion of the area of ​​the side is formed in the first direction to an extent that the movement of the thread 211 in the first direction is guided.

[0045] In an embodiment, at least one inlet 340, 350 may be formed at the upper end and / or lower end of the coupling part 300. This may be formed by spacing the multiple coupling units 310 in the circumferential direction of the coupling part 300. For example, at least one first inlet 340 may be formed between the multiple coupling units 310 located at the uppermost end, and at least one second inlet 350 may be formed between the multiple coupling units 310 located at the lowermost end. When the plug part 200 is coupled to the coupling part 300, the end of the thread 211 may enter the first groove 320 through the first inlet 340, and when the plug part 200 is completely coupled to the coupling part 300, the end of the thread 211 may leave the first groove 320 through the second inlet 350. In addition, when the stopper portion 200 is separated from the coupling portion 300, the end of the thread 211 can enter the first groove 320 through the second entrance / exit 350, and when the stopper portion 200 is completely separated from the coupling portion 300, the end of the thread 211 can disengage from the first groove 320 through the first entrance / exit 340.

[0046] In the embodiment, the first inlet 340 may guide the end of the thread 211 into the first groove 320. More specifically, when the end of the thread 211 is disposed at a predetermined position on the first inlet 340, the end of the thread 211 may move toward the first groove 320 by riding on the surface of the coupling unit 310 due to gravity. That is, regardless of the alignment position of the plug part 200 and the coupling part 300, the end of the thread 211 may be guided into the first groove 320 by the first inlet 340, and the thread 211 may move on the first groove 320, so that the plug part 200 and the coupling part 300 may be automatically coupled together, simply by disposing the plug part 200 on the upper end of the coupling part 300.

[0047] In an embodiment, the coupling part 300 may include at least one first fixing part 360, and the plug part 200 may include at least one second fixing part 212 correspondingly. For example, the first fixing part 360 may be formed on the lower side of the coupling unit 310, and the second fixing part 212 may be formed on the lower side of the thread 211. While the first fixing part 360 and the second fixing part 212 are in contact with each other, the coupling between the plug part 200 and the coupling part 300 can be maintained. Specifically, the first fixing part 360 and the second fixing part 212 are in contact with each other when the thread 211 has completely passed through the first groove 320. At this time, in order to separate the plug part 200, an external force is required to the extent that the second fixing part 212 can overcome the first fixing part 360, and the plug part 200 cannot be separated from the coupling part 300 without the action of an external force of a predetermined magnitude or more.

[0048] In the embodiment, the first fixing part 360 may be composed of at least one first coupling protrusion protruding outward from the coupling part 300, and the second fixing part 212 may be composed of a plurality of second coupling protrusions protruding inward from the plug part 200. The first fixing part 360 may be inserted between the second coupling protrusions. In this case, both sides of the first coupling protrusion may be formed as a support wall that supports the second coupling protrusion while contacting the second coupling protrusion. However, this is not limited thereto, and various configurations may be applied, such as the first fixing part 360 being composed of a plurality of first coupling protrusions, the second fixing part 212 being composed of at least one second coupling protrusion, and the second coupling protrusion being inserted between the first coupling protrusions, depending on the embodiment.

[0049] In an embodiment, the upper end of the first fixing part 360 may be formed with a curved surface that connects support walls formed on both sides of the first fixing part 360. When the plug part 200 is coupled to or separated from the coupling part 300, the second fixing part 212 may move while being in contact with the curved surface.

[0050] In the embodiment, a region of the lower end of the second fixed part 212 may protrude downward compared to the other region. In this case, when the second fixed part 212 moves on the first fixed part 360, the region of the second fixed part 212 protruding downward can move on the curved surface of the first fixed part 360 (e.g., while elastically deforming). That is, as a region of the lower end of the second fixed part 212 protrudes downward, the other region of the second fixed part 212 is no longer in contact with the first fixed part 360, and the contact area between the second fixed part 212 and the first fixed part 360 is reduced, and thus the second fixed part 212 can easily move on the first fixed part 360 by elastic deformation, etc.

[0051] In the embodiment, during the process of coupling and / or separation between the plug 200 and the coupling part 300, a certain resistance is generated between the first fixing part 360 and the second fixing part 212, and the generated resistance is transmitted to a user, so that the user can easily know whether coupling and / or separation has occurred. Specifically, when the plug 200 is coupled to or separated from the coupling part 300, if the lower surface (and / or the surface adjacent thereto) of the second fixing part 212 comes into contact with the upper surface (and / or the surface adjacent thereto) of the first fixing part 360, resistance in a direction for releasing the contact (i.e., a separation direction or a coupling direction) may be generated due to friction between the first fixing part 360 and the second fixing part 212, etc.

[0052] In an embodiment, at least one of the first fixing portion 360 and the second fixing portion 212 may be formed in a number corresponding to the threads 211. Thus, when the plug 200 is coupled to the coupling portion 300, the first fixing portion 360 and the second fixing portion 212 may abut against each other regardless of the initial alignment position of the plug 200. For example, two first fixing portions 360 may be formed on both ends of the coupling portion 300, and the second fixing portions 212 may be formed in a number corresponding to the threads 211 along the inner circumferential surface of the lower end of the plug 200, but are not limited thereto.

[0053] The content container 1000 in FIG. 1 to FIG. 3 is an example, and various configurations can be applied depending on the embodiment to which the present invention is applied. For example, the coupling part 300 can be formed in one region of the plug part 200. For example, the coupling part 300 can be formed on the inside of the plug part 200, and a plurality of coupling units 310 can be formed along the inner circumferential surface of the plug part 200. In this case, at least one thread is formed on the neck part of the container part 100, and the container part 100 and the coupling part 300 are screwed together, so that the plug part 200 can be coupled to the container part 100. Also, for example, the coupling part 300 can be configured in a plurality of parts, and each coupling part 300 can be located in the container part 100 and the plug part 200. Specifically, the first coupling part can be provided in the container part 100 (particularly, at the position of the neck part of the container part 100), and the second coupling part can be provided in the plug part 200 (particularly, inside the plug part 200). In this case, a plurality of first coupling units are formed along the outer circumferential surface of the container portion 100, and a plurality of second coupling units are formed along the inner circumferential surface of the plug portion 200, and the first coupling units and the second coupling units are mutually coupled to couple the container portion 100 and the plug portion 200. Although the embodiment in which the position or configuration of the coupling portion 300 is changed in this manner can be described in the same manner as in Figures 1 to 3, redundant description will be omitted for simplicity of explanation.

[0054] 4 is a diagram for explaining the coupling between a coupling unit and a screw thread according to an embodiment of the present invention. Specifically, Fig. 4(a) shows a conventional screw coupling structure, and Fig. 4(b) shows a coupling structure according to an embodiment of the present invention.

[0055] First, according to the conventional screw connection structure shown in FIG. 4(a), when two members are connected to each other by a first thread A1 and a second thread A2, frictional force is generated in the entire area where the first thread A1 and the second thread A2 contact each other.

[0056] Meanwhile, referring to FIG. 4(b), when the plug 200 and the coupling part 300 are coupled to each other through the thread 211 and the multiple coupling units 310, a non-contact area between the thread 211 and the coupling unit 310 may occur due to the second groove 330 between the multiple coupling units 310. In particular, the cross-sectional area of ​​the coupling unit 310 decreases toward the protruding direction, and the contact area between the thread 211 and the coupling unit 310 may further decrease, resulting in a decrease in friction between the coupling unit 310 and the thread 211. When the plug 200 and the coupling part 300 are aligned such that the thread 211 is disposed between the multiple coupling units 310 due to the decrease in friction, the thread 211 can automatically move on the first groove 320 due to gravity alone or with little external force.

[0057] The coupling between the coupling unit 310 and the thread 211 shown in FIG. 4 is exemplary, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0058] FIG. 5 is a diagram illustrating a coupling unit according to an embodiment of the present invention.

[0059] 5(a) and 5(b), the bottom surface of the coupling units 310-1 and 310-2 may be polygonal. In this case, the bottom surface of the polygon may be generally straight as shown in FIG. 5(a), or may have a curved line in some areas as shown in FIG. 5(b). In this case, the bottom surface of the coupling units 310-1 and 310-2 may guide the movement of the screw thread 211 in the first direction by at least one side generally formed in the first direction.

[0060] 5(c), the bottom surface of the coupling unit 310-3 may be formed in an elliptical shape. When the bottom surface is formed in an elliptical shape, at least a part of the circumference of the bottom surface is formed in a first direction, and the screw thread 211 may be guided to move in the first direction. For example, the direction of the long axis or the direction of the short axis of the ellipse may correspond to the first direction.

[0061] Referring to FIG. 5(d), the bottom surface of the coupling unit 310-4 may be formed in a circular shape. When the bottom surface is formed in a circular shape, the interval between the multiple coupling units 310-4 may be adjusted to guide the thread 211 to move in the first direction. For example, the interval between the multiple coupling units 310-4 in the first direction may be adjusted to be smaller than the interval between the multiple coupling units 310-4 in the second direction. Such an interval between the multiple coupling units 310-4 may be applied to the coupling units 310-1 and 310-2 having polygonal bottom surfaces or the coupling unit 310-3 having an elliptical bottom surface, in addition to the coupling unit 310-4 having a circular bottom surface.

[0062] The shape of the bottom surface of the coupling unit 310 can be appropriately selected according to the coupling strength between the plug 200 and the coupling part 300, the aesthetics to be formed, and the like. For example, when it is desired to improve the coupling strength, the coupling units 310-1 and 310-2 having polygonal bottom surfaces, especially the coupling unit 310-1 formed generally in straight lines, can be selected to increase the contact area with the thread 211. Conversely, when it is desired to reduce the coupling strength between the plug 200 and the coupling part 300, the coupling unit 310-3 having an elliptical bottom surface or the coupling unit 310-4 having a circular bottom surface can be selected to reduce the contact area with the thread 211. Also, for example, when it is desired to form a sharp and angular aesthetics through the coupling unit 310, the coupling units 310-1 and 310-2 having polygonal bottom surfaces can be selected, and conversely, when it is desired to form a round and gentle aesthetics through the coupling unit 310, the coupling unit 310-3 having an elliptical bottom surface or the coupling unit 310-4 having a circular bottom surface can be selected. Moreover, such a selection is merely an example, and the shape of the coupling unit 310 may be selected by comprehensively considering various factors.

[0063] The shape of the coupling unit 310 in FIG. 5 is merely exemplary, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0064] FIG. 6 is a diagram illustrating a coupling unit according to an embodiment of the present invention.

[0065] 6, the bottom surface of the coupling unit 310, 310', 310'' may be formed in a diamond shape. In this case, angles D1 to D3 of the top vertex of the diamond-shaped bottom surface may be appropriately selected within a range in which movement along the first groove 320 of the thread 211 is possible and the coupling is stably maintained.

[0066] For example, as shown in FIG. 6, the angle of the upper vertex of the bottom surface of the coupling unit 310, 310', 310'' may be 49.5° (see FIG. 5(a)) to 160° (see FIG. 5(c)), preferably 115° (see FIG. 5(b)).

[0067] If the angle of the top apex is less than 49.5°, the first grooves 320, 320', 320'' may be formed too steeply, which may cause a problem that the plug part 200 is too easily separated from the coupling part 300. Also, if the angle of the top apex is more than 160°, the first grooves 320, 320', 320'' may be formed too gently, which may require too many turns to couple the plug part 200 to the coupling part 300, or the plug part 200 may not automatically couple to the coupling part 300.

[0068] The shapes and upper apex angles of the coupling units 310, 310', 310'' shown in FIG. 6 are merely exemplary, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0069] FIG. 7 is an exploded perspective view of a plug according to an embodiment of the present invention.

[0070] 7, the plug part 200 may include an inner plug 210 and an outer plug 220. The inner plug 210 may be coupled to the coupling part 300 by forming a screw thread 211 and a second fixing part 212 on the inside, and the outer plug 220 may be coupled to surround the inner plug 210 and shield the inner plug 210 from the outside.

[0071] In an embodiment, the inner plug 210 and the outer plug 220 may be mated together. For this purpose, for example, at least one mating protrusion 213 may be formed on the outer side of the inner plug 210, and at least one mating groove 221 corresponding to the mating protrusion 213 may be formed on the inner side of the outer plug 220. However, this is not limited thereto, and various known methods of mating such as screw mating and lock mating may be used for the inner plug 210 and the outer plug 220.

[0072] 7 is merely an example, and various configurations may be applied depending on the embodiment to which the present invention is applied. For example, the inner plug 210 may have a coupling portion 300 formed thereon instead of a screw thread 211, and the screw thread 211 may be formed on the container portion 100 correspondingly.

[0073] The drawings and the specification disclose the best mode for carrying out the present invention. Although specific terms are used herein, they are merely used for the purpose of describing the present invention, and are not used to limit the meaning or the scope of the present invention described in the claims. Therefore, a person having ordinary skill in the art will understand that various modifications and equivalent other embodiments are possible. Therefore, the true technical scope of the present invention should be determined by the technical ideas of the appended claims.
