Description

Pressurized dispensing cosmetic container

[0001] The present invention relates to a cosmetic container, and more specifically, to a pressurized dispensing type cosmetic container that can be used more stably and conveniently by controlling a pressing operation and a refilling operation by attaching and detaching an overcap.

[0002] In today's modern society, people of all ages and genders are using cosmetics according to their needs in accordance with the rapidly diversifying trend of the times. In particular, women are using various types of cosmetics and cosmetics and tools with various colors, and through research and development by cosmetics companies, a variety of high-quality cosmetics and tools are being released to the market every day.

[0003] If we classify the above cosmetics by their purpose of use, they are classified into facial cleansing cosmetics used to remove sebum, waste products, and pollutants from the skin surface, basic cosmetics used to provide the skin with an appropriate amount of moisture and oil, color cosmetics used to express beautiful colors, hair cosmetics used to remove foreign substances from the hair or scalp while protecting and nourishing the hair, and perfumes used to dissolve fragrances in alcohol and other substances to give off a scent to others.

[0004] Meanwhile, as living standards improve and interest in the safety of cosmetic compositions and skin beauty increases, many cosmetics are manufactured using natural ingredients. However, these cosmetics do not contain preservatives or other additives to minimize skin irritation, which makes them more susceptible to spoilage than cosmetics manufactured using chemical ingredients. For example, the cosmetics may become contaminated or spoiled when exposed to external air during use, resulting in bacterial infiltration or oxidation of the composition.

[0005] In addition, among the above cosmetics, in order to store and use cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, and rinses, a container having a simple opening and closing function is generally used, and the cosmetics are taken out of the container with a spatula or fingers and applied to the skin or hair for use. However, such conventional containers have a problem in that the amount of cosmetics dispensed cannot always be controlled at a constant level, resulting in wastage of cosmetics.

[0006] Accordingly, a pump-type cosmetic container was developed that minimizes contact between cosmetics and outside air, is convenient to use, and can control the amount of cosmetics dispensed at a constant level.

[0007] The above pump-type cosmetic container comprises a container body that holds contents, a pressurized pump that is provided at an opening of the container body and is operated by pressing, and a nozzle head that is connected to the pressurized pump and is connected to the upper part of the container body, and when the nozzle head exposed to the outside is pressed downward, the contents held in the container body are discharged to the outside in a certain amount by the pumping operation of the pressurized pump.

[0008] The above-mentioned pump-type cosmetic container has the advantages of being economical because the contents contained in the container body do not come into contact with the outside air, the contents are not excessively discharged through the nozzle outlet, and it is convenient to use because it is a pumping method using pressure.

[0009] However, the conventional pump-type cosmetic container does not have a separate refill structure for the cosmetic contents, so the entire cosmetic container must be discarded, which requires additional purchase costs, which not only places an economic burden on consumers but also has the problem of wasting resources.

[0010] In order to solve the above problems, a refillable pumping container is disclosed in Patent No. 10-1252115, which comprises: an inner container that contains contents; a pumping member that discharges the contents through a pumping action; an outer container that contains the inner container and the pumping member and has an open bottom so that the inner container and the pumping member can be replaced; and a discharge unit that is connected to the upper portion of the outer container so as to be in communication with the pumping member and discharges the contents to the outside through the pumping action of the pumping member according to the elevation and descent of the inner container.

[0011] However, the above-mentioned conventional technology has a structure in which a pumping container is configured as a double container of an inner container and an outer container, the outer container and the inner container are connected by a pumping member, and the inner container is refilled by pulling it out from the open lower part of the outer container. Therefore, there was a problem in that the inner container was pulled out from the outer container due to carelessness in use, or the pumping member and the outer container were separated due to external impact.

[0012] In addition, the above-mentioned conventional technology has an unsanitary problem in that when the bottom of the container is pressed during storage or carrying, the pumping member malfunctions and the cosmetic contents contained inside the container are discharged to the outside, which not only causes waste of the cosmetic contents but also makes the surrounding area dirty due to the discharged cosmetic contents.

[0013] Accordingly, it became necessary to develop a pressurized dispensing type cosmetic container that could prevent unintentional dispensing of cosmetic contents due to malfunction of the pumping member, as well as limit the content from being arbitrarily separated from the outer container due to carelessness or external impact.

[0016] (Patent Document 001) Registered Patent No. 10-1252115 (Announced on April 12, 2013)

[0017]

[0018] In order to solve the above problems, the present invention aims to provide a pressurized dispensing type cosmetic container that allows for convenient use of cosmetic contents without malfunction and more stable refilling operations by attaching or detaching an overcap to one side of the container body to allow or restrict pressing operation and refilling operation of the contents container with respect to the container body.

[0019] In order to achieve the above object, the present invention provides a pressure-discharge type cosmetic container including a container body having a discharge port formed therein; an overcap detachably attached to the container body; a contents container movably coupled within the container body and containing cosmetic contents therein; a discharge means installed in the contents container for discharging the cosmetic contents; a fixed locking member coupled to one side of the contents container and having a first locking protrusion formed therein; a guide member coupled to the inside of the container body; a movable locking member installed in the guide member and moved by the overcap and having a second locking protrusion formed therein, and an elastic member providing elasticity to the movable locking member.

[0020] In addition, the overcap may be combined or separated from the container body to restrict or allow the operation of the refill and discharge means of the contents container.

[0021] In addition, a locking hole is formed in the above container body, and a locking button is formed in the above movable locking member so that it protrudes outward while penetrating the locking hole, or a protrusion is formed on the inner periphery of the above overcap so that it can be inserted into the locking hole.

[0022] In addition, the container body includes a nozzle having a discharge port formed in the center, and the nozzle can be fixed within the container body by a guide member.

[0023] In addition, the above-mentioned contents container may be composed of a contents container main body having an inlet formed therein and a contents container support exposed to the outside of the container main body and may be combined with each other.

[0024] In addition, the discharge means can be detachably connected to a nozzle or guide member of the container body.

[0025] In addition, it is preferable that the discharge means is a pump that discharges the contents by pumping.

[0026] In addition, the first locking projection may be formed to protrude from the outer surface of the fixed locking member toward the movable locking member, and the second locking projection may be formed to protrude from the inner surface of the movable locking member toward the fixed locking member.

[0027] In addition, the guide member and the movable locking member may be formed with a first guide part and a second guide part, respectively, which guide the direction of movement of the movable locking member with respect to the guide member.

[0028] In addition, the movable locking member may be positioned adjacent to the fixed locking member and may be formed of an operation control part having a lock button protruding therefrom and a refill control part formed on both sides of the operation control part and having a second locking projection formed thereon.

[0029] In addition, as the movable locking member moves due to the combination of the container body and the overcap, a part of the movable locking member may be positioned at the top of the fixed locking member, thereby restricting the operation of the discharge means.

[0030] In addition, as the movable locking member moves by combining the container body and the overcap, the second locking projection of the movable locking member and the first locking projection of the fixed locking member are shifted upward and downward relative to each other, and the second locking projection is positioned below the first locking projection, thereby preventing the contents container from being separated from the container body.

[0031] According to an embodiment of the present invention, by attaching or detaching an overcap to one side of the container body to allow or restrict the pressing operation of the contents container with respect to the container body, not only can the contents of the cosmetic be conveniently dispensed and used, but waste of the contents of the cosmetic due to malfunction can be prevented, and the contents of the cosmetic can be used hygienically.

[0032] According to an embodiment of the present invention, by attaching or detaching an overcap to one side of the container body to allow or restrict refilling of the contents container for the container body, the contents container is prevented from being separated due to the user's carelessness or external impact, thereby enabling the refilling operation to be performed more stably.

[0046]

[0047] Hereinafter, with reference to the attached drawings, a pressurized discharge type cosmetic container according to an embodiment of the present invention will be described in detail.

[0048] FIG. 1 is a perspective view of a cosmetic container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view from above of a cosmetic container according to an embodiment of the present invention, FIG. 3 is an exploded perspective view from below of a cosmetic container according to an embodiment of the present invention, FIG. 4 is a cross-sectional view taken along line AA of a cosmetic container according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along line BB of a cosmetic container according to an embodiment of the present invention.

[0049] As illustrated, a pressurized dispensing type cosmetic container according to an embodiment of the present invention may be configured to include a container body (10), an overcap (20), a content container (30), a dispensing means (40), a fixed locking member (50), a guide member (60), a movable locking member (70), and an elastic member (80).

[0050]

[0051] A pressurized discharge type cosmetic container according to one embodiment of the present invention is described by dividing it into each component as follows.

[0052]

[0053] The above container body (10) is a component that forms the exterior of a cosmetic container, and one side is open, and a content container (30) is inserted into this open portion, and may be formed of a hard material to protect the content container (30). In the pressurized discharge type cosmetic container according to the embodiment of the present invention, the container body (10) is illustrated as a cylindrical shape with an empty interior, but the container body (10) is not limited to the above shape, and may be formed in various shapes and materials in consideration of the arrangement of the content container (30) stored therein, usability, design elements, etc.

[0054] As shown in FIGS. 2 and 3, the container body (10) may include a discharge surface (12) through which cosmetic contents are discharged. The discharge surface (12) is formed to protrude on one side of the container body (10) and is a portion that comes into contact with the user's skin. When the container body (10) and the overcap (20) are combined, the discharge surface (12) is wrapped by the overcap (20) and is protected from the outside, and an exposure hole (12a) is formed in the center thereof to expose the end of the nozzle (18) to the outside. It is preferable that the discharge surface (12) be formed into a smooth curved surface for convenience of use or aesthetics.

[0055] A locking hole (14) may be formed in the container body (10). The locking hole (14) is a hole formed in the side wall of the container body (10), and when at least a part of the movable locking member (70) protrudes outward through the locking hole (14), or when at least a part of the overcap (20) is inserted into the inside of the container body (10), the overcap (20) and the movable locking member (70) may be linked to each other. That is, when the overcap (20) is coupled to the container body (10), the overcap (20) pushes the movable locking member (70) toward the inside of the container body (10) and operates, and when the overcap (20) is separated from the container body (10), the movable locking member (70) is restored to its original position by the elastic restoring force of the elastic member (80). At this time, it is preferable that the locking hole (14) be formed on the outer periphery of the container body (10) that is adjacent to the discharge surface (12), i.e., the side wall that comes into contact with the overcap (20) when combined.

[0056] Meanwhile, the container body (10) may include a nozzle (18) that discharges cosmetic contents to the outside. One side of the nozzle (18) is exposed to the outside through an exposure hole (12a) of the container body (10), and the other side is detachably coupled to a discharge means (40). A discharge port (18a) is formed in the center of the nozzle (18) and is connected to the discharge means (40). The nozzle (18) may be fixed to the inside of the discharge surface (12) of the container body (10) while a portion protruding from the outer periphery is pressed by a guide member (60).

[0057]

[0058] The above overcap (20) is detachably and attachably coupled to one side of the container body (10) and protects the discharge surface (12) of the container body (10) from the outside. In the drawing of the pressurized discharge type cosmetic container according to the embodiment of the present invention, the container body (10) and the overcap (20) are each illustrated as having protrusions formed thereon and being undercut coupled to each other, but the present invention is not limited thereto and may have various types of coupling structures within the range in which the overcap (20) can be easily attached or detached from the container body (10), such as coupling by protrusions and grooves, forced fitting coupling, and screw coupling.

[0059] Meanwhile, the overcap (20) is coupled or separated from the container body (10) and is linked to the movable locking member (70), thereby controlling the operation of the refill and discharge means (40) of the contents container (30). That is, when the container body (10) and the overcap (20) are combined, the overcap (20) pushes at least a portion of the movable locking member (70) into the inner space of the container body (10), so that the movable locking member (70) restricts the movement of the fixed locking member (50), thereby making the refill and discharge means (40) of the content container (30) impossible to operate. When the container body (10) and the overcap (20) are separated, the movable locking member (70), which has been moved into the inner space of the container body (10), is restored by the elastic restoring force of the elastic member (80), so that the movable locking member (70) allows the movement of the fixed locking member (50), thereby making the refill and discharge means (40) of the content container (30) possible to operate. At this time, at least a part of the overcap (20) may be inserted into the locking hole (14) of the container body (10) and come into contact with the movable locking member (70), or at least a part of the movable locking member (70) may protrude outward through the locking hole (14) of the container body (10) and come into contact with the inner wall of the overcap (20). It is preferable that the overcap (20) be combined with the container body (10) while coming into contact with the side wall adjacent to the discharge surface (12) of the container body (10), i.e., the outer periphery where the locking hole (14) of the container body (10) is formed, for smooth operation of the movable locking member (70).

[0060] The above container body (10), overcap (20), content container (30), fixed locking member (50), guide member (60), and movable locking member (70) are formed of a thermosetting resin or a thermoplastic resin, and the thermosetting resin is preferably formed of at least one material selected from the group consisting of epoxy resin, amino resin, phenol resin, and polyester resin, and the thermoplastic resin is preferably formed of at least one material selected from the group consisting of polyethylene, acrylic resin, polypropylene, polystyrene, polyvinyl chloride, Teflon, nylon, and polyacetal resin, and in particular, it is most preferable to form it of a polypropylene material. Of course, the above-mentioned container body (10), overcap (20), content container (30), fixed locking member (50), guide member (60), and movable locking member (70) are not limited to the materials described above, and may be formed of various other materials.

[0061]

[0062] The above-mentioned contents container (30) is reciprocally movably coupled within the container body (10), and cosmetic contents are stored therein. The contents container (30) is a storage body in which liquid or gel contents are stored, and at least a portion of the contents container (30) is inserted and stored into the inner space of the container body (10).

[0063] As shown in FIGS. 4 and 5, the contents container (30) is composed of a contents container main body (32) having an inlet (32a) formed therein and a contents container holder (34) exposed to the outside of the container body (10), which can be fixedly connected to each other. Of course, the contents container (30) may be injection-molded as a single unit without being divided into the contents container main body (32) and the contents container holder (34).

[0064] Cosmetic contents are filled through the inlet (32a) of the above-mentioned contents container main body (32), and the discharge means (40) and the fixed locking member (50) are coupled to the inlet (32a) and fixed to one side of the contents container (30), and the contents container support (34) protrudes into the open portion of the container main body (10) and, when pressed by a user, moves the contents container (30) and the discharge means (40) coupled to the contents container (30) and the fixed locking member (50) toward the discharge surface (12) of the container main body (10).

[0065] Meanwhile, a piston (36) may be formed inside the content container (30). The piston (36) is configured to be pushed upward toward the discharge means (40) in proportion to the amount of discharged cosmetic contents, and a piston wing (36a) is formed on the outer periphery of the piston (36) to be in close contact with the inner periphery of the content container (30). A discharge means insertion groove (36b) is formed in the center of the piston (36), and when the piston (36) reaches the inner upper part of the content container (30), at least a portion of the discharge means (40) is inserted into the discharge means insertion groove (36b), thereby minimizing the remaining amount of cosmetic contents.

[0066]

[0067] The above discharge means (40) is installed at the inlet (32a) of the contents container (30) or at a position adjacent to the inlet (32a) to discharge the contents stored in the contents container (30) to the outside in fixed quantities. The discharge means (40) is fixed to the inlet (32a) of the contents container (30) while being pressed by the fixed locking member (50), and one side can be inserted through the inlet (32a) of the contents container (30), and the other side can be connected to the discharge port (18a) of the container body (10). At this time, one end of the discharge means (40) can be detachably coupled to the nozzle (18) or the guide member (60) of the container body (10).

[0068] The above discharge means (40) is preferably a pump that discharges a fixed amount of contents to the outside by a pumping action. The above discharge means (40) may be composed of a housing (41) that is inserted into the inlet (32a) of the contents container (30) and has a contents suction port (41a) formed at the bottom, a suction valve plate (42) that opens and closes the contents suction port (41a) of the housing (41), a sealing cap (43) that is coupled while surrounding the upper part of the housing (41), a stem (44) that reciprocates in the pumping operation direction while penetrating the sealing cap (43), an elastic spring (45) that elastically supports the stem (44), an operating discharge pipe (46) that is coupled to the stem (44) and reciprocates together with it, and an operating discharge ring (47) that is fitted to the outside of the operating discharge pipe (46) and is in close contact with the inner circumference of the housing (41).

[0069]

[0070] The above fixed locking member (50) is coupled to one side of the contents container (30) and moves or refills together with the contents container (30) within the container body (10). The fixed locking member (50) is fixedly coupled while surrounding the inlet portion (32a) of the contents container (30), and can fix the discharge means (40) inside the inlet portion (32a) of the contents container (30) while pressing the edge portion of the discharge means (40).

[0071] As seen in FIGS. 2 and 3, the fixed locking member (50) is configured to control the operation of the refill and discharge means (40) of the contents container (30) together with the movable locking member (70), and is formed as a hollow cylinder to surround the inlet (32a) of the contents container (30), and the discharge means (40) can pass through the center thereof.

[0072] The above fixed locking member (50) may be formed of an operation control panel (51), a lower inner wall (52) formed to extend downward from the operation control panel (51), and a lower outer wall (53) formed to extend downward from the operation control panel (51) at a predetermined distance to the outside of the lower inner wall (52). The operation control panel (51) is a plate-shaped plate having a predetermined area and is mounted on the upper end of the inlet (32a) of the contents container (30), and the lower inner wall (52) is inserted into the inlet (32a) of the contents container (30) so that its end presses against the edge of the discharge means (40) and fixes it, and the lower outer wall (53) is fixedly connected to the inlet (32a) while surrounding the outside of the inlet (32a) of the contents container (30).

[0073] A first locking projection (54) may be formed on the above fixed locking member (50). The first locking projection (54) is formed to protrude from the outer surface of the operating control panel (51) toward the movable locking member (70), and together with the movable locking member (70), restricts the refilling of the contents container (30). That is, the first locking projection (54) of the fixed locking member (50) is positioned above the second locking projection (74a) formed on the movable locking member (70) while being alternated up and down with the second locking projection (74a) when the movable locking member (70) moves by the overcap (20), so that the contents container (30) and the discharge means (40) combined with the fixed locking member (50) do not fall out from the container body (10), thereby limiting the refilling of the contents container (30) to the container body (10). At this time, it is preferable that the first locking projection (54) be formed in at least two or more to be arranged symmetrically with respect to the second locking projection (74a) for a stable engaging action.

[0074]

[0075] The above guide member (60) is coupled to the inside of the container body (10) and guides the movement direction of the movement locking member (70). The guide member (60) has a curved upper surface so that it is in close contact with the opposite side of the discharge surface (12) of the container body (10), and its edge is in close contact with the inner wall of the container body (10) so that it is coupled with the container body (10), and can be detachably coupled with the discharge means (40).

[0076] The above guide member (60) is formed in a three-dimensional shape and is fixed to an inner space adjacent to the discharge surface (12) of the container body (10). A locking member insertion space (61) into which a movable locking member (70) is inserted is formed in the guide member (60), and a through hole (63) through which a nozzle (18) passes is formed in the center thereof, and a pressing portion (65) is formed to protrude inside the through hole (63) so as to press the nozzle (18) and fix the nozzle (18).

[0077] A first engaging protrusion (67) is formed on the outside of the locking member insertion space (61) of the above guide member (60), and a second engaging protrusion (17) is formed on the inside of the container body (10) so that they can be engaged with each other. At this time, it is preferable that the first engaging protrusion (67) protrudes from the edge of the guide member (60) toward the inner wall of the container body (10), and the second engaging protrusion (17) protrudes from the inner wall of the container body (10) toward the guide member (60).

[0078] Meanwhile, a first guide portion (64) may be formed in the inner space of the guide member (60). The first guide portion (64) is a portion that guides the movement direction of the movement locking member (70) with respect to the guide member (60), and is formed to protrude from the inner wall of the guide member (60), and at least a portion of the movement locking member (70) is seated on the upper surface of the first guide portion (64). The first guide portion (64) is preferably formed in at least two or more pieces to face each other for smooth movement of the movement locking member (70), and is preferably formed to extend a certain section along the movement direction of the movement locking member (70).

[0079] And, a first limiting protrusion (64a) may be formed on one surface of the first guide portion (64). The first limiting protrusion (64a) is a portion that limits the range of movement of the movement locking member (70) from the guide member (60), and is formed to protrude from one surface of the first guide portion (64), and at least a portion of the movement locking member (70) is caught and stopped by the first limiting protrusion (64a). At this time, it is preferable that the first limiting protrusion (64a) protrude from one surface of the first guide portion (60) facing each other toward the movement locking member (70).

[0080] An elastic member fitting projection (66) is formed on the above guide member (60), and an elastic member (80) can be fitted into the elastic member fitting projection (66). It is preferable that the elastic member fitting projection (66) be formed to protrude in a direction that elastically supports the movable locking member (70) on the inner wall of the guide member (60).

[0081]

[0082] The above-mentioned movable locking member (70) is movably installed within the guide member (60), and moves back and forth in and out of the container body (10) by attaching and detaching the overcap (20), thereby controlling the operation of the refill and discharge means (40) of the content container (30).

[0083] The above-mentioned movable locking member (70) moves along the guide member (60) to overlap the fixed locking member (50) when the container body (10) and the overcap (20) are combined, thereby restricting the movement of the fixed locking member (50) and preventing the refilling of the content container (30) and the operation of the discharge means (40). In addition, when the container body (10) and the overcap (20) are separated, the movable locking member (70) moves away from the fixed locking member (50) along the guide member (60) and allows the movement of the fixed locking member (50), thereby enabling the refilling of the content container (30) and the operation of the discharge means (40).

[0084] As seen in FIGS. 2 and 3, the movable locking member (70) is positioned adjacent to the fixed locking member (50), and may be formed of an operation control part (72) in which a lock button (72a) is protruded and a refill control part (74) formed at both ends of the operation control part (72) and in which a second locking projection (74a) is formed.

[0085] The above-described operation control unit (72) controls the operation of the discharge means (40) and is disposed on the outside adjacent to the fixed locking member (50). The operation control unit (72) is pushed by the overcap (20) and moves toward the fixed locking member (50) and is positioned at the upper end of the operation control panel (51) of the fixed locking member (50), thereby preventing the contents container (30) and the discharge means (40) combined with the fixed locking member (50) from moving toward the discharge surface (12) of the container body (10) and limiting the operation of the discharge means (40) by the pressurization of the contents container (30). At this time, it is preferable that the operation control unit (72) surround a part of the fixed locking member (50) and at least one side is formed as a smooth curved surface corresponding to one side of the fixed locking member (50).

[0086] A lock button (72a) is formed in the center of the above operation control unit (72). The lock button (72a) protrudes outward through the lock hole (14) of the container body (10) and can come into contact with the inner periphery of the overcap (20) when the container body (20) and the overcap (20) are combined. In the pressurized discharge type cosmetic container according to one embodiment of the present invention, a lock button (72a) is formed on a movable locking member (70) and protrudes outward from the container body (10), and the lock button (72a) is pushed by an overcap (20) and moves toward the inside of the container body (10) as an example, but is not limited thereto, and a protrusion may be formed on the inner periphery of the overcap (20) and inserted into the inside of the container body (10), and the movable locking member (70) may be pushed by the protrusion of the overcap (20) and move toward the inside of the container body (10).

[0087] The above refill control unit (74) is a part that controls the refilling of the contents container (30), and is formed to extend along both sides of the fixed locking member (50) from both ends of the operation control unit (72), and moves back and forth together with the operation control unit (72). At this time, it is preferable that the refill control unit (74) be formed as a three-dimensional block having a constant volume.

[0088] A second locking projection (74a) may be formed on the refill control unit (74). The second locking projection (74a) is formed to protrude from the inner surface of the refill control unit (74), i.e., from the mutually facing surfaces, toward the fixed locking member (50), and is linked to the fixed locking member (50) to restrict the refilling of the contents container (30). That is, the second locking protrusion (74a) is positioned below the first locking protrusion (54) while being offset up and down from the first locking protrusion (54) of the fixed locking member (50) when the movable locking member (70) is moved by the overcap (20), so that the contents container (30) and the discharge means (40) combined with the fixed locking member (50) do not come off from the container body (10), thereby limiting the refilling of the contents container (30) to the container body (10). At this time, it is preferable that the second locking protrusion (74a) be formed as at least one pair to be symmetrically arranged while facing each other for a stable engaging action with the first locking protrusion (54).

[0089] Meanwhile, a second guide portion (74b) may be formed in the refill control portion (74). The second guide portion (74b) is a portion that guides the movement direction of the movement locking member (70) with respect to the guide member (60), and is formed by being sunken into the outer surface of the refill control portion (74), and the first guide portion (64) of the guide member (60) is inserted into the second guide portion (74b). The second guide portions (74b) are preferably formed in at least two or more to be arranged symmetrically with each other for smooth movement of the movement locking member (70), and are formed to extend a certain section along the movement direction of the movement locking member (70).

[0090] And, a second limiting protrusion (74c) may be formed on the second guide portion (74b). The second limiting protrusion (74c) is a portion that limits the range of movement of the movement locking member (70) from the guide member (60), and is formed to protrude on the inner wall of the second guide portion (74b) and is stopped by being caught by the first limiting protrusion (64a) of the guide member (60). It is preferable that the second limiting protrusion (74c) protrude from the refill control portion (74) toward the guide member (60).

[0091] An elastic member insertion groove (74d) having a certain width and depth is formed in the refill control unit (74), and at least a portion of an elastic member (80) can be inserted into the elastic member insertion groove (74d). It is preferable that the elastic member insertion groove (74d) be formed so as to be recessed in one surface of the refill control unit (74) in a direction that elastically supports the movement locking member (70).

[0092]

[0093] The above elastic member (80) is installed between the guide member (60) and the movable locking member (70) to provide elasticity to the movable locking member (70).

[0094] The elastic member (80) can elastically support the movable locking member (70) with respect to the guide member (60) by having one side fitted into the elastic member insertion protrusion (66) of the guide member (60) and the other side inserted into the elastic member insertion groove (74d) of the movable locking member (70). That is, the elastic member (80) is compressed by being pressed by the movable locking member (70) when the container body (10) and the overcap (20) are coupled, and then elastically restored when the container body (10) and the overcap (20) are separated, thereby moving the movable locking member (70) to its original position.

[0095] At this time, it is preferable that the elastic member (80) is formed as a coil spring made by spirally winding a metal or plastic having a certain elasticity. In the pressurized discharge type cosmetic container according to one embodiment of the present invention, the elastic member (80) is formed separately from the guide member (60) and the movable locking member (70) and is a coil spring that provides elasticity to the movable locking member (70) as an example, but is not limited thereto, and may be formed integrally with either the guide member (60) or the movable locking member (70), and an end thereof may be elastically contacted with the other one to elastically connect the guide member (60) and the movable locking member (70).

[0096]

[0097] According to one embodiment of the present invention, a pressurized dispensing type cosmetic container allows or restricts the pressing operation of a content container (30) with respect to the container body (10) by attaching or detaching an overcap (20) to one side of the container body (10), thereby conveniently dispensing and using cosmetic contents, preventing waste of cosmetic contents due to malfunction, and enabling hygienic use. In addition, by attaching or detaching an overcap (20) to one side of the container body (10) to allow or restrict the refilling operation of the content container (30) with respect to the container body (10), the content container (30) is prevented from being separated due to the user's carelessness or external impact, thereby enabling the refilling operation to be performed more stably.

[0098]

[0099] FIGS. 6 to 9 are drawings illustrating a process of using and refilling a pressure-dispensing cosmetic container according to an embodiment of the present invention. With reference to these drawings, a method of using and refilling a pressure-dispensing cosmetic container according to an embodiment of the present invention will be described.

[0100] FIG. 6 is a perspective view illustrating a state in which refilling and operation of a cosmetic container according to an embodiment of the present invention are restricted, FIG. 7 is a perspective view illustrating a state in which refilling and operation of a cosmetic container according to an embodiment of the present invention are permitted, FIG. 8 is a cross-sectional view taken along the line AA illustrating a state in which a content container of a cosmetic container is pressed and operated according to an embodiment of the present invention, and FIG. 9 is a cross-sectional view taken along the line AA illustrating a state in which a content container is separated from a container body of a cosmetic container according to an embodiment of the present invention.

[0101] In order to use a pressurized discharge type cosmetic container according to one embodiment of the present invention, first, the overcap (20) coupled to one side of the container body (10) is separated to enable operation and refilling of the content container (30).

[0102] As shown in Fig. 6, when the overcap (20) is coupled to one side of the container body (10), the lock button (72a) of the movable locking member (70) is pushed by the inner wall of the overcap (20), causing the movable locking member (70) to move toward the fixed locking member (50) along the guide member (60).

[0103] As described above, when the movable locking member (70) is moved toward the inside of the container body (10), the second locking projection (74a) of the movable locking member (70) is positioned below the first locking projection (54) of the fixed locking member (50) while being alternated up and down, so that the contents container (30) and the discharge means (40) combined with the fixed locking member (50) do not fall out of the container body (10), and at the same time, the operation control unit (72) of the movable locking member (70) is positioned at the upper end of the operation control panel (51) of the fixed locking member (50), so that the contents container (30) and the discharge means (40) combined with the fixed locking member (50) can be prevented from moving to the discharge surface (12) of the container body (10).

[0104] Thereafter, as shown in Fig. 7, when the overcap (20) is separated from the container body (10), the movable locking member (70) is pushed by the elastic restoring force of the elastic member (80) and moves away from the fixed locking member (50) along the guide member (60). At this time, the locking button (72a) of the movable locking member (70) penetrates the locking hole (14) of the container body (10) and protrudes outward, and the second limiting protrusion (74c) of the movable locking member (70) is caught by the first limiting protrusion (64a) of the guide member (60) to stop the movement.

[0105] As described above, when the movable locking member (70) is moved to the outside of the container body (10), the second locking projection (74a) of the movable locking member (70) is separated from the lower portion of the first locking projection (54) of the fixed locking member (50), and the engagement of the fixed locking member (50) is released, so that the contents container (30) and the discharge means (40) combined with the fixed locking member (50) become detachable from the container body (10), and at the same time, the operation control unit (72) of the movable locking member (70) is separated from the upper portion of the operation control panel (51) of the fixed locking member (50), so that the movement of the fixed locking member (50) is permitted, thereby enabling the pressurization of the contents container (30) combined with the fixed locking member (50) and the operation of the discharge means (40).

[0106] Thereafter, as shown in FIG. 8, when the bottom of the contents container (30) is pressed, the fixed locking member (50) and the discharge means (40) combined with the contents container (30) move toward the discharge surface (12) of the container body (10), and the cosmetic contents are pumped by the discharge means (40) and discharged to the discharge surface (12) through the discharge port (18a) of the nozzle (18). In more detail, when the discharge means (40) is pressed by the content container (30), the stem (44) of the discharge means (40) and the operating discharge pipe (46) coupled to the lower part of the stem (44) are fixed, and as the housing (41) and the operating discharge ring (47) move toward the nozzle (18), a gap is created between the operating discharge pipe (46) and the operating discharge ring (47), and as the content container (30) continues to be pressed, the operating discharge ring (47) comes into contact with the end of the stem (44) and is fixed together with the operating discharge pipe (46), thereby reducing the volume inside the housing (41). Accordingly, the suction valve plate (42) closes the contents suction port (41a) by the discharge pressure within the housing (41), and the cosmetic contents contained within the housing (41) come out between the operating discharge pipe (46) and the operating discharge ring (47), pass through the passage formed in the center of the operating discharge pipe (46), and are then discharged to the outside through the discharge port (18a) of the nozzle (18).

[0107] Thereafter, when the pressurization of the contents container (30) is released, the elastic spring (45) of the discharge means (40) is elastically restored, and as the housing (41), the operating discharge ring (47), and the contents container (30) move to their original positions, the volume inside the housing (41) increases, vacuum pressure is generated, the suction valve plate (42) is lifted, the contents suction port (41a) is opened, and the cosmetic contents flow into the housing (41), and the piston (36) provided in the contents container (30) moves toward the discharge means (40) in proportion to the discharged cosmetic contents.

[0108] Meanwhile, when all of the cosmetic contents contained in the content container (30) are used up, the content container (30) can be refilled. As shown in FIG. 9, when the content container (30) is pulled out from the container body (10), the connection between the nozzle (18) or the guide member (60) and the discharge means (40) is released, and the content container (30), the discharge means (40), and the fixed locking member (50) are separated from the container body (10). Thereafter, a new content container (30), the discharge means (40), and the fixed locking member (50) are inserted into the open portion of the container body (10) to replace them.
