Description

Title of the invention: COSMETIC CONTAINER HAVING A REFILLABLE STRUCTURE CONTEXT OF THE INVENTION

[0001] 1. Scope of the invention

[0002] The present invention relates to a cosmetic container having a refill structure, and more particularly, a cosmetic container having a refill structure in which a content container, a release mechanism, an inner cap, and an actuation button are moved up and down from a container body by turning an outer cap so as to be used or replaced conveniently.

[0003] 2. Description of related art

[0004] In today's modern society, men and women of all ages use cosmetics as needed, in line with the trend of rapid diversification. In particular, women use cosmetic products and tools of various types and colors, and different high-quality cosmetic products and tools are brought to market daily through the research and development of companies in the cosmetics industry.

[0005] According to the purpose of use, cosmetics are classified into, for example, facial cleansing cosmetics used to remove sebum, waste and contaminants from a skin surface, basic cosmetics used to properly provide hydration and oils to the skin, colored cosmetics used to display pretty colors, hair cosmetics used to protect the hair and provide nourishment as well as to remove foreign substances from the hair or scalp, and perfumes obtained by dissolving odorous materials in alcohol or other and used to give a scent to others.

[0006] Furthermore, cosmetics are manufactured from natural raw materials because interest in the stability of cosmetic compositions and skin beauty is increasing due to improved living standards. However, since preservatives are not added to the above-mentioned cosmetics to minimize skin irritation, the risk of spoilage is relatively high compared to cosmetics made from chemical raw materials. For example, cosmetics made from natural raw materials can be contaminated or spoiled when bacteria penetrate them due to contact with outside air. during use or the composition is oxidized due to contact with air.

[0007] Furthermore, a container with a simple opening and closing function is generally used to store and use cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, and conditioners, among the cosmetics mentioned above. The cosmetics are dispensed from the container using a spatula or a finger and applied to the skin or hair. However, the conventional container described above does not consistently regulate the amount of cosmetics dispensed, and consequently, some cosmetics are wasted.

[0008] Consequently, a pump-type cosmetic container minimizing contact between cosmetics and outside air and used practically to constantly regulate the amount of cosmetics released has been developed.

[0009] The pump-type cosmetic container comprises: a container body configured to receive contents; a pressure pump supplied in an opening of the container body and operated by pressing; and a nozzle head coupled to an upper portion of the container body while being connected to the pressure pump, in which the contents received in the container body are released outwards in a predetermined quantity by the pumping operation of the pressure pump when the nozzle head exposed to the outside is pressed down.

[0010] According to the pump-type cosmetic container described above, the contents received in the container body cannot come into contact with the outside air. It is economical because the contents are not excessively released through a nozzle release orifice, and it is convenient to use since the cosmetic container functions even when the container body is placed on the floor.

[0011] However, according to the conventional cosmetic container, the push button is unintentionally pressed due to user negligence during storage or transport, and the contents of the container are released outwards. Consequently, the relatively expensive cosmetics are wasted and the surrounding area is soiled by the released contents.

[0012] Furthermore, the conventional cosmetic container is stored or transported in a state where the release orifice of the push-button for dispensing the contents is fully open. Consequently, the container becomes contaminated when foreign substances enter the open dispensing orifice, and the contaminated contents are released and used, thus creating unhygienic conditions.

[0013] In order to resolve the aforementioned problems, Korean patent registration No. 10-1267966 (hereinafter referred to as the "related art") describes an airless pump cosmetic container having a retractable actuating button. The above related art is configured so that the airless pump actuation button appears and disappears after being moved up and down at the top side of the cosmetic container, and consequently the actuation button is fully inserted into the container to prevent the actuation button from protruding outwards when not in use due to transport and storage, so as to ensure safety by avoiding malfunctions due to negligence and other factors, and to facilitate actuation by pumping by causing the actuation button to protrude outwards during use.

[0014] However, since the related art does not have a separate internal refilling structure, the entire cosmetic container must be discarded after all the contents stored in the container have been used. Consequently, resources are wasted, and environmental pollution accelerates due to the discarded containers.

[0015] Therefore, it is necessary to develop a cosmetic container to conveniently refill the inner container holding the contents while avoiding malfunction of the actuation button and contamination of the contents.

[0046] When a part "includes" an element in the present invention, the above expression does not exclude other elements, but may further include other elements, unless otherwise specified in particular.

[0047] A cosmetic container having a refill structure according to the embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0048] Figure 1 is a perspective view showing a cosmetic container according to an embodiment of the present invention. Figure 2 is an exploded perspective view showing the cosmetic container according to an embodiment of the present invention. Figure 3 is a cross-sectional view showing the cosmetic container according to an embodiment of the present invention.

[0049] As shown in the drawings, the cosmetic container having a refill structure according to the embodiment of the present invention can include a container body 10, an outer cap 20, a lifting mechanism 30, a content container 40, a release mechanism 50, an inner cap 60 and an actuation button 70.

[0050] Each component of the cosmetic container having a refill structure according to the embodiment of the present invention shall be described as follows.

[0051] The container body 10 has a rigid cylindrical shape with one open end and defines the external appearance of a cosmetic container together with an outer cap 20. The container body 10 is not limited to a rigid cylinder and may have various shapes and be made of various materials depending on the types of contents stored therein, ease of use, design factors, or other considerations. However, it may be preferable to have a narrow width and a relatively long length so as to allow a user to easily hold the container body 10.

[0052] As shown in [Fig. 2], a coupling portion 12 is formed in the container body 10, in which the coupling portion 12 can extend from one end of the container body 10 and be inserted into the outer cap 20. At least one pair of spiral lifting grooves 12a are formed in the coupling portion 12 to guide upward and downward movements of the lifting mechanism 30. In other words, a lifting projection 32 of the lifting mechanism 30 is inserted into the spiral lifting groove 12a, and the lifting projection 32 is rotated in a predetermined section by the outer cap 20 and moved along the spiral lifting groove 12a, so that the lifting mechanism 30 is progressively raised or lowered. It can be preferably that the spiral elevation groove 12a extends in a regular curve having a predetermined angle of inclination along an outer wall of the coupling part 12, and that one end is open for mounting the elevation projection 32.

[0053] Furthermore, the angle of inclination of the spiral lifting groove 12a can be changed so that the rotation area, lifting speed, and ease of use of the lifting mechanism 30 can be adjusted. For example, when the angle of inclination of the spiral lifting groove 12a is relatively steep, the rotation range of the outer cap 20 for fully raising the lifting mechanism 30 is shortened, and consequently, the lifting mechanism 30 can be raised and lowered more quickly. Conversely, when the angle of inclination of the spiral lifting groove 12a is relatively gentle, the rotation range of the outer cap 20 for fully raising the lifting mechanism 30 becomes longer, and consequently, the lifting mechanism 30 can be raised and lowered slowly and smoothly.Therefore, the spiral lifting groove 12a can be formed on the outer wall of the coupling part 12 to have a suitable angle of inclination taking into consideration as a whole the rotation section, the lifting speed, the ease of use, and other aspects of the lifting mechanism 30.

[0054] The outer cap 20 is rotationally coupled to one side of the container body 10, and rotated by the user to rotate the lifting mechanism 30 provided therein.

[0055] As shown in [Fig. 2], the outer cap 20 has a cylindrical shape with two open ends, and it may be preferable for it to have the same diameter as the container body 10 for design continuity. The outer cap 20 has one open end into which the coupling portion 12 of the container body 10 is inserted, and into which the lifting mechanism 30, the inner cap 60, and the actuating button 70 are received, and the other open end through which the actuating button 70 is extended or retracted.

[0056] A straight elevation groove 22 is formed on an inner circumference of the outer cap 20, in which the elevation projection 32 passing through the spiral elevation groove 12a is inserted into the straight elevation groove 22, so as to rotate the elevation mechanism 30 and simultaneously guide a vertical displacement of the elevation projection 32. It may be preferable that a pair of straight elevation grooves 22 be formed at positions facing each other to correspond to the spiral elevation groove 12a and the elevation projection 32, and are elongated in a predetermined section in a longitudinal direction of the outer cap 20.

[0057] In addition, the outer cap 20 is provided in an upper inner side thereof with an insertion space 24 into which a protruding part 76 formed in the actuation button 70 is inserted, and an anti-pressure protrusion 26 is formed below the insertion space 24, to prevent the actuation button 70 from being pressed from inside the outer cap 20 and actuated.

[0058] The lifting mechanism 30 is coupled to an inside of the coupling part 12 of the container body 10, and raised or lowered in the container body 10 and the outer cap 20 while being rotated jointly with the outer cap 20.

[0059] At least one pair of elevation projections 32 can project outwards from the outer circumference of the lifting mechanism 30. The elevation projection 32 is inserted into the straight elevation groove 22 of the outer cap 20 while passing through the spiral elevation groove 12a of the container body 10, and moved along the spiral elevation groove 12a and the straight elevation groove 22 when the outer cap 20 is rotated.In other words, the lifting projection 32 of the lifting mechanism 30 is rotated jointly with the outer cap 20 by the straight lifting groove 22 of the outer cap 20, and raised or lowered in the container body 10 by the spiral lifting groove 12a of the container body 10, so that the inner cap 60 and the content container 40, the release mechanism 50 and the actuating button 70 coupled to the inner cap 60 are simultaneously moved up and down. It may be preferable for the lifting projections 32 to be formed in pairs like the straight lifting grooves 22 and arranged on opposite sides of each other.

[0060] As shown in the partially enlarged view of [Fig.2], a fastening projection 34 detachably coupled to the inner cap 60 projects from the inner circumference of the lifting mechanism 30, in which the fastening projection 34 can extend over a predetermined section along the inner circumference of the lifting mechanism 30. In addition, elastic slots 34a to provide elasticity to the fastening projection 34 can be formed on both sides of the fastening projection 34.The elastic slot 34a can extend vertically for a predetermined section at both ends of the fixing projection 34, in which the fixing projection 34 is inclined outwards and elastically returned to the initial position when the lifting mechanism 30 and the inner cap 60 are attached and detached, and consequently, the lifting mechanism 30 and the inner cap 60 can be easily coupled or separated.

[0061] Furthermore, a reloading guide groove 36 can be formed on the inner circumference of the lifting mechanism 30. The reloading guide groove 36 can to guide the direction of separation or insertion of the following components, so that refilling operations of the inner cap 60 and the content container 40, the release mechanism 50, and the actuating button 70 coupled to the inner cap 60 are carried out easily. The refill guide groove 36 is formed on the inner circumference of the lifting mechanism 30 in a straight line in a predetermined section along the direction in which the content container 40 is inserted or separated, and it may be preferable that one end of the refill guide groove 36, i.e., the end in the direction in which the inner cap 60 is separated, can be open, and the other end, i.e., the end in the direction in which the inner cap 60 is inserted, can be closed.

[0062] Oblique guide surfaces 36a can be formed on both lateral walls of the open portion of the reload guide groove 36 to guide the reload guide protrusion 66 formed on the inner cap 60 so that it is correctly inserted. It may be preferable for the oblique guide surface 36a to be inclined at a predetermined angle in a direction outwards from the reload guide groove 36. In other words, the oblique guide surface 36a can widen the entry width of the reload guide groove 36 to guide the insertion position of the reload guide protrusion 66, so that the reload guide protrusion 66 can be more easily inserted into the reload guide groove 36.

[0063] Furthermore, a friction projection 38 can project outwards from an upper outer circumference of the lifting mechanism 30, and the friction projection 38 can come into close contact with an inner wall of the coupling part 12 of the container body 10, so as to generate friction between the container body 10 and the lifting mechanism 30 when the lifting mechanism 30 is rotated by the outer cap 20. As a result, the impression of rotation can be expected to improve during the rotation operation of the outer cap 20.

[0064] The content container 40 serving as a storage element for storing a liquid or gel content in it is inserted and stored in an internal space of the container body 10.

[0065] An inlet portion 42 can be formed on one side of the content container 40. The contents can be filled through the inlet portion 42, and a portion of the release mechanism 50 described later can be inserted into it. It may be preferable for a thread to be formed on the outer circumference of the inlet portion 42, so as to be coupled by screw to the thread formed on the lower inner circumference of the inner cap 60. In the container for In cosmetics according to the embodiment of the present invention, the container 40 and the inner cap 60 are shown to be screwed together. However, the present invention is not limited to this and can be implemented in various coupling systems, for example, a coupling between projections and grooves, or a coupling or connection by forced fit, in order to permanently and stably couple the container 40 and the inner cap 60.

[0066] The release mechanism 50 is installed in the inlet portion 42 of the content container 40 or at a position adjacent to the inlet portion 42, so as to release the contents stored in the content container 40. In other words, while being installed inside the inner cap 60, the release mechanism 50 has one side inserted through the inlet portion 42 of the content container 40 and the other side connected to the actuating button 70. It may be preferable for the release metering pump 50 to be a pump for releasing a fixed quantity of contents to the outside by means of the pumping operation.

[0067] As shown in [Fig. 3], the release mechanism 50 may include: a housing 51 inserted into the inlet portion 42 of the content container 40 and provided in a lower portion thereof with a content suction orifice 51a; a suction tube 52 connected to the content suction orifice 51a and inserted into the content container 40; a suction valve plate 53 for opening and closing the content suction orifice 51a of the housing 51; a sealing cap 54 surrounding an upper portion of the housing 51 and coupled thereto; a rod 55 moving back and forth in a pumping direction while passing through the sealing cap 54; an elastic spring 56 for elastically supporting the rod 55; an operating release pipe 57 coupled to the rod 55 and animated in a back-and-forth motion together;and an operating release ring 58 assembled with an outer side of the operating release pipe 57 and coming into close contact with the inner circumference of the housing 51. ;

[0068] Furthermore, a sealing ring 59 may be further provided between the housing 51 of the release mechanism 50 and the inlet portion 42 of the content container 40, so that airtightness inside the content container 40 may be maintained. The sealing ring 59 is made of an elastic material to further improve the sealing strength of the content container 40; it may be preferable for it to be made of at least one material among urethane rubber, natural rubber, elastomer, nitrile butadiene rubber (NBR), and silicone, or polypropylene, polyethylene, or acrylonitrile butadiene styrene (ABS) having an elastic material, and in particular, it may be most desirable for it to be made of thermoplastic elastomer TPE plastic as a material between rubber and plastic with softness and excellent durability.

[0069] The inner cap 60 is coupled to the inlet portion 42 of the content container 40, and rises or falls jointly with the lifting mechanism 30 while being fixed to the lifting mechanism 30, in which the release mechanism 50 can be installed while passing through a center of the inner cap 60. A lower inner wall 61 can extend downwards from the inner cap 60, and a lower outer wall 63 can extend downwards while being spaced at a predetermined interval from an outer side of the lower inner wall 61, and a thread can be formed on an inner circumference of the lower outer wall 63 so as to be coupled by screw to the thread formed in the inlet portion 42 of the content container 40.

[0070] As shown in [Fig.2], a mounting groove 64 detachably coupled to the lifting mechanism 30 is formed on the outer circumference of the inner cap 60, in which the mounting projection 34 of the lifting mechanism 30 can be coupled to the mounting groove 64. The mounting groove 64 can extend entirely along the outer circumference of the inner cap 60.

[0071] In addition, a refill guide protrusion 66 is formed on the outer circumference of the inner cap 60, into which the refill guide protrusion 66 can be inserted into the refill guide groove 36 of the lifting mechanism 30. The refill guide protrusion 66 can be formed on the outer circumference of the inner cap 60 in a straight line for a predetermined section along the direction in which the content container 40 is inserted or separated, and it can be arranged below the fixing groove 64 so as to allow the refill guide protrusion 66 to be inserted into the refill guide groove 36, and to sequentially fix the fixing groove 64 and the fixing protrusion 34.

[0072] Furthermore, as shown in [Fig. 3], a locking jaw 67 can project outwards from the upper portion of the retaining groove 64 of the inner cap 60, so that the inner cap 60 is not at risk of being separated within the container body 10. At least one straight guide hole 68 can be formed in the upper portion of the inner cap 60, so that linear reciprocating movements of the actuating button 70 can be guided. It may be preferable for the straight guide hole 68 to extend for a predetermined cross-section along the direction of movement of the actuating button 70.

[0073] The actuation button 70 is coupled to the release mechanism 50 to release the contents stored in the content container 40 outwards while being animated by a vertical back-and-forth movement by a user pressing operation.

[0074] A release passage 72 can be formed in a center of the actuation button 70 so as to be connected to the release mechanism 50.

[0075] A nozzle mating hole 74 can be formed on one side of the release passage 72, and a nozzle 80 having a release orifice 82 can be mated to the nozzle mating hole 74. It may be preferable for the nozzle 80 to be completely inserted into the nozzle mating hole 74.

[0076] Furthermore, the protruding portion 76 can protrude outwards from the outer circumference of the actuating button 70. When the actuating button 70 is retracted into the outer cap 20, the protruding portion 76 is inserted into the insertion space 24 of the outer cap 20, and positioned on an upper end of an anti-pressure level 26 to restrict pressure on the actuating button 70. Consequently, during storage or transport of the cosmetic container, the actuating button 70 inserted into the outer cap 20 is not at risk of being depressed and malfunctioning due to external force.

[0077] In addition, at least one straight guide projection 78 may project from the inner circumference of the actuating button 70 so as to be inserted into the straight guide hole 68 of the inner cap 60. It may be preferable for the straight guide projection 78, like the straight guide hole 68 of the inner cap 60, to extend for a predetermined section along the direction of movement of the actuating button 70.

[0078] As described above, according to the cosmetic container of the embodiment of the present invention, the content container, the release mechanism, the inner cap, and the actuation button are raised and lowered in a predetermined section by turning the outer cap, and a portion of the latter is extended or retracted from the container body, so that the convenience of use is improved, that the actuation button may not be actuated by an external force unrelated to an intention of the user while being transported or stored, that the entire cosmetic container may not be discarded when the contents stored in the content container are exhausted, and that only the content container combined with the release mechanism, the inner cap, and the actuation button may be replaced from the container body.Therefore, the user's financial burden can be reduced, and resource waste and environmental pollution can be minimized. Furthermore, according to the cosmetic container of the embodiment of the present invention, the contents container, the release mechanism, the inner cap, and the actuating button, which are raised and lowered together from the container body, can be easily separated after being removed from the container body, and can be easily secured after being pushed into the inner space of the container body. so that the recharging operation can proceed more easily.

[0079] Figures 4 to 9 are drawings illustrating the use and refilling of the cosmetic container having a refill structure according to the embodiment of the present invention. The method for using and refilling the cosmetic container having a refill structure according to the embodiment of the present invention will be described with reference to the drawings above.

[0081] In order to use the cosmetic container having a refill structure according to the present invention, the container body 10 is retained and the outer cap 20 is turned in one direction.

[0082] As shown in [Fig. 5], when the outer cap 20 is rotated relative to the container body 10, the lifting projection 32 of the lifting mechanism 30, inserted into the straight lifting groove 22 of the outer cap 20, is rotated together with the outer cap 20, and the lifting projection 32 is simultaneously moved upwards along the spiral lifting groove 12a of the container body 10. As the inner cap 60, fixed to the lifting mechanism 30 and the content container 40, the release mechanism 50 and the actuating button 70 coupled to the inner cap 60 gradually rise, the actuating button 70 is extended outwards from the outer cap 20. The lifting projection 32 of the lifting mechanism 30 is moved in a straight line in the straight lifting groove 22 of the outer cap 20.

[0083] Subsequently, as shown in [Fig. 6], when the release mechanism 50 coupled to the actuating button 70 is under pressure by pressing the actuating button 70 exposed externally, the rod 55 of the release mechanism 50 and the The operating release tube 57 coupled to the lower portion of the rod 55 are moved downwards together. Since the operating release ring 58 comes into close contact with the inner surface of the housing 51, only the operating release tube 57 is moved downwards, and consequently a gap is created between the operating release tube 57 and the operating release ring 58, thus creating a passage for the contents.

[0084] Subsequently, when the actuating button 70 is continuously pressed, the lower end of the rod 55, displaced downwards by the actuating button 70, presses on the operating release ring 58, such that the operating release ring 58 is displaced downwards in conjunction with the operating release tube 57, thus reducing the volume inside the housing 51. As a result, the suction valve plate 53 closes the content suction orifice 51a due to the release pressure in the housing 51, and the contents received in the housing 51 simultaneously escape between the operating release tube 57 and the operating release ring 58, pass through an inlet passage formed in the center of the operating release tube 57, and are released towards the release orifice 82 of the nozzle 80 via the release passage 72 of the button actuation 70.

[0085] Subsequently, as shown in [Fig. 7], when the pressure on the actuating button 70 is released, the elastic spring 56, which elastically supports the rod 55 of the release mechanism 50, returns to its original shape, so that the rod 55 is moved upwards, and the operating release tube 57 coupled to the lower side of the rod 55 is also moved upwards. The lower portion of the operating release tube 57 pulls the operating release ring 58 upwards, and the gap between the operating release tube 57 and the operating release ring 58 is closed, so that the operating release tube 57 and the operating release ring 58 are moved upwards together, and consequently, the volume inside the housing 51 increases, thus generating the vacuum pressure.

[0086] Subsequently, the suction valve plate 53 is lifted by the vacuum pressure generated inside the housing 51, and as a result, the content suction orifice 51a formed on the lower surface of the housing 51 is opened, so that the content received in the inner container 20 is introduced into the housing 51 through the suction tube 52.

[0087] Once the makeup application is complete, the actuating button 70 is inserted into the outer cap 20 for storage or transport. When the outer cap 20 is turned in the opposite direction, the lifting protrusion 32 of the lifting mechanism 30 engages in the straight lifting groove 22 of the cap The outer part 20 is rotated jointly with the outer cap 20, and the lifting projection 32 is simultaneously moved downwards along the spiral lifting groove 12a of the container body 10. As the inner cap 60, fixed to the lifting mechanism 30 and the content container 40, the release mechanism 50 and the actuating button 70 coupled to the inner cap 60 gradually descend, the actuating button 70 is retracted into the outer cap 20, as shown in [Fig. 4]. The lifting projection 32 of the lifting mechanism 30 is moved in a straight line into the straight lifting groove 22 of the outer cap 20.

[0088] Furthermore, when the contents received in the content container 40 are completely used, the content container 40 can be replaced and used. As shown in [Fig.[8] when the outer cap 20 is rotated relative to the container body 10 to push the actuating button 70 outwards from the outer cap 20, and the actuating button 70 is removed from the container body 10, the inner cap 60 is removed together with the actuating button 70, and the fastening between the fastening protrusion 34 formed in the lifting mechanism 30 and the fastening groove 64 formed in the inner cap 60 are simultaneously released, so that the lifting mechanism 30 and the inner cap 60 are separated, and continuously, the inner cap 60 and the content container 40, the release mechanism 50 and the actuating button 70 coupled to the inner cap 60 escape together from the container body 10 and the outer cap 20.

[0089] As shown in [Fig.9], the release mechanism 50, the inner cap 60 and the actuating button 70 coupled to a new content container 40 are inserted into the container body 10 while being inserted into the open portion of the outer cap 20. The refill guide protrusion 66 of the inner cap 60 is guided to the correct position by the oblique guide surface 36a of the lifting mechanism 30, and inserted into the refill guide groove 36, so that the refilling operation takes place easily.
