Description

Contents container containing the pump assembly

[0001] The present invention relates to a contents container including a pump assembly, and more particularly, to an environmentally friendly contents container including a pump assembly that can be formed of a single series of materials and is thus easy to recycle, and having a refillable contents container.

[0002] In general, a pump container may be configured to discharge contents to the outside through a pumping action of a pump assembly coupled to the upper part of the container body. The pump container may include a container body in which contents are stored, and a pump assembly coupled to the upper part of the container body and configured to create a vacuum inside the container body and draw up contents through a pumping action. Here, the pump assembly performs a pumping action to discharge contents stored in the container body to the outside, and may include a spring that provides elasticity inside for repetitive pumping action. Typically, the spring is made of a different material from the components of other pump assemblies made of plastic, so the spring must be separated and disposed of in order to recycle the pump assembly, which makes recycling difficult.

[0003] In addition, there is a problem that since containers for contents, such as pump containers, must be disposed of after all contents have been used, environmental pollution occurs, and production costs increase because new containers for contents must be produced each time.

[0004] The present invention is intended to solve the above problem, and its purpose is to provide a pump assembly including an elastic member made of a single series of materials and components of other pump assemblies, and a contents container including the same.

[0005] In addition, the purpose is to provide a container for contents that is easy to refill by configuring the container body into an outer container that can be reused repeatedly and an inner container that can be refilled, and by easily attaching and detaching the inner container to the outer container.

[0006] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0007] According to an embodiment of the present invention, a contents container includes: a pump assembly; and a container body detachably coupled to the pump assembly, wherein the pump assembly includes: a cylinder that vertically penetrates to provide a passage for introducing and discharging contents; an undercap coupled to the cylinder and supporting a lower end of an elastic member; a stem that transfers the contents and supports an upper end of the elastic member; and an elastic member positioned between the stem and the undercap to surround the stem and provide an elastic force from the undercap toward the stem according to an external force, wherein the undercap may have an air passage formed at an upper end thereof to relieve compression and expansion of air due to compression and decompression of the elastic member.

[0008] According to another embodiment of the present invention, a contents container comprises: a pump assembly; a container body including an inner container and an outer container; and a housing portion detachably connecting the container body and the pump assembly, wherein the outer container includes a guide portion including a ramp formed from the top to the bottom on an inner surface thereof, and the housing portion includes a first guide protrusion and a second guide protrusion formed on a first outer surface thereof so as to be movable along the ramp, and when the inner container is connected to the pump assembly through the housing portion and rotates with respect to the outer container, the first guide protrusion and the second guide protrusion move along the ramp so that the inner container can be connected to or separated from the outer container in a vertical direction.

[0009] According to the present invention, since the elastic member is composed of a single series of materials with the components of other pump assemblies, the pump assembly can be disposed of at once without being disassembled, making it environmentally friendly.

[0010] In addition, according to the present invention, an air passage can be formed at the top of the undercap to relieve compression and expansion of air due to compression and decompression of the elastic member.

[0011] In addition, according to the present invention, a second mounting portion is formed on the lower surface of the wing portion of the stem, where the upper end of the elastic member is mounted, and a first mounting portion is formed in a groove along the circumference of the upper end of the under cap, where the lower end of the elastic member is mounted, so that the elastic member can be fixed without a separate configuration.

[0012] In addition, according to the present invention, a guide part including a ramp formed from the top downward on the inner surface of the outer container, and a first guide protrusion and a second guide protrusion formed on the first outer surface of the housing part so as to be movable along the ramp, when the inner container is coupled to the pump assembly through the housing part and rotates with respect to the outer container, the first guide protrusion and the second guide protrusion move along the ramp and the inner container is coupled or separated from the outer container in the vertical direction, thereby providing a structure that is easy to refill.

[0037]

[0038] FIG. 1 is an exploded perspective view of a contents container according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of a pump assembly according to an embodiment of the present invention, FIG. 3 is a perspective view showing a combined structure of a cap portion, a housing portion, and an outer container according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view showing a pumping operation of a contents container according to an embodiment of the present invention.

[0039] Referring to FIGS. 1 to 4, a contents container (1000) according to an embodiment of the present invention may include a pump assembly (100), a head portion (200), a cap portion (300), and a container body (400).

[0040] The pump assembly (100) receives an external force from a user, generates a pressure change inside, and thereby introduces and discharges contents. When pressurized, the contents contained in the container body (400) can be moved to the head portion (200) and discharged. The pump assembly (100) according to one embodiment may include a cylinder (110), a check valve (120), a ring (130), a piston rod (140), a seal cap (150), an under cap (160), an elastic member (170), and a stem (180).

[0041] The cylinder (110) may be vertically perforated to provide a space for the contents to be introduced and discharged. In one embodiment, the cylinder (110) is positioned inside the upper portion (e.g., the spout portion) of the container (410), and has a mounting wing formed on the outside so that it can be mounted on the upper portion of the container (410). The lower portion of the cylinder (110) may be formed to extend toward the interior of the container (410), and an inlet communicating with the container (410) may be formed.

[0042] The check valve (120) may be located at or adjacent to the inlet of the cylinder (110). In one embodiment, the check valve (120) serves as a backflow prevention valve, which closes the inlet when the internal pressure of the cylinder (110) is positive, and opens the inlet when the internal pressure of the cylinder (110) changes to negative.

[0043] The ring (130) may be positioned between the mounting wing of the cylinder (110) and the top (e.g., the spout) of the container (410). In one embodiment, the ring (130) may allow the mounting wing of the cylinder (110) to be mounted on the top of the container (410). The ring (130) may be omitted, and if the ring (130) is omitted, the mounting wing of the cylinder (110) may be mounted directly on the top of the container (410).

[0044] A piston rod (140) may be inserted into the cylinder (110), the lower side may be surrounded by a seal cap (150), and the upper side may be connected to a stem (180). The piston rod (140) may have a hollow tube shape. In one embodiment, an inlet that is opened and closed by the seal cap (150) is formed at the lower side of the piston rod (140), an outlet for discharging contents introduced through the inlet is formed at the upper side of the piston rod (140), and a connecting passage connecting the inlet and the outlet may be formed. A support may be formed at the lower side of the piston rod (140), and when the inner lower side of the seal cap (150) is in close contact with the support, the inlet may be sealed from the inner space of the cylinder (110).

[0045] In one embodiment, the piston rod (140) can change the internal pressure of the cylinder (110) by moving up and down according to an external force. More specifically, the piston rod (140) can move vertically within the cylinder (110) by the stem (180). When the piston rod (140) moves downward, the support portion is spaced apart from the inner lower part of the seal cap (150), thereby opening the inlet port, so that the contents within the cylinder (110) can flow into the piston rod (140). When the piston rod (140) continues to move, the contents can move to the outlet port through the connecting passage, be discharged, and then be discharged through the discharge hole of the nozzle via the stem (180). When the piston rod (140) moves upward, the seal cap (150) can seal the inlet of the piston rod (140), and negative pressure is generated inside the cylinder (110), so that the contents inside the container body (400) can flow into the cylinder (110).

[0046] The seal cap (150) is for opening and closing the piston rod (140), and its outer surface can be in close contact with the cylinder (110) and its inner surface can be in close contact with the piston rod (140). The lower end of the inner surface of the seal cap (150) can be in close contact with the support portion of the piston rod (140) to seal the inlet portion of the piston rod (140). When the piston rod (140) descends, the lower end of the seal cap (150) and the support portion of the piston rod (140) move away from each other, opening the inlet portion, so that the connection passage between the inside of the cylinder (110) and the piston rod (140) can be communicated.

[0047] The under cap (160) is coupled to the upper end of the cylinder (110) and may be configured such that its lower end extends inwardly of the cylinder (110). The under cap (160) performs sealing and may also be referred to as a sealing portion. In one embodiment, the under cap (160) may include a side wall that comes into contact with the cylinder (110) and a base portion that is formed inwardly from the lower end of the side wall. The rising of the seal cap (150) may be suppressed by the lower surface of the base portion (or a protrusion formed on the lower surface of the base portion).

[0048] In one embodiment, an air passage (162) may be formed in the under cap (160) to relieve compression and expansion of air due to compression and decompression of the elastic member (170) at the top. More specifically, when the elastic member (170) is implemented as a bellows type, the compression and expansion of internal air that occurs when the elastic member (170) is compressed and decompressed may be relieved by the air passage (162). Furthermore, the air passage (162) may also relieve compression of internal air that occurs when the pump assembly (100) and the inner container (410) are coupled.

[0049] In one embodiment, the undercap (160) may have a groove formed inwardly along the circumference at the top. This groove may be referred to as a first mounting portion (161), and the first mounting portion (161) supports the lower end of the elastic member (170) and prevents the elastic member (170) from being dislodged.

[0050] In one embodiment, the air passage (162) may be formed as a groove deeper than the first mounting portion (161).

[0051] The elastic member (170) is for restoring the position of the piston rod (140), and its lower end may be supported by the under cap (160), and its upper end may be supported by the stem (180). When the user presses the head portion (200), more specifically, the button portion (230), the stem (180) and the piston rod (140) may move downward, thereby compressing the elastic member (170). At this time, the compression of the internal air due to the compression of the elastic member (170) may be relieved by the air passage (162). When the user releases the pressure, the elastic member (170) may be restored by the elastic force, and the stem (180) and the piston rod (140) may be returned to their original positions. At this time, the expansion of the internal air due to the decompression of the elastic member (170) may be relieved by the air passage (162).

[0052] In one embodiment, the elastic member (170) may have a length longer than the stroke distance of the piston rod (140). At this time, the length of the elastic member (170) is a length in a steady state when the elastic member (170) is not compressed or stretched, and may be, for example, 1.4 to 3 times the stroke distance of the piston rod (140). However, the present invention is not limited thereto, and the length of the elastic member (170) may be variously set depending on the material, shape, etc. of the elastic member (170). That is, the length of the elastic member (170) may be determined so that the compression distance of the elastic member (170) after deformation corresponds to or is close to the stroke distance of the piston rod (140), taking into account deformation due to repeated compression.

[0053] In one embodiment, the elastic member (170) may be accommodated in the pump assembly (100) in a partially compressed state. To this end, the elastic member (170) may have a length longer than the accommodation space of the pump assembly (100) (e.g., the space between the stem (180) and the under cap (160). For example, the elastic member (170) may have a length 1.3 to 3 times longer or 1.7 to 2.2 times longer than each accommodation space, but is not limited thereto. In this way, since the elastic member (170) is accommodated in the pump assembly (100) in a partially compressed state, even if the elastic member (170) is deformed such that its recovery rate decreases due to repeated compression, the elastic member (170) can operate stably without the need for a change in the size of the accommodation space that accommodates the elastic member (170).

[0054] In one embodiment, at least a portion of the elastic member (170) may be made of a soft plastic material. For example, the material may include polypropylene (PP), polyethylene (PE), or the like. However, the present invention is not limited thereto. By using a soft plastic material, the manufacturing of the elastic member (170) can be facilitated. Furthermore, the pump assembly (100) can be disposed of in one go without disassembling, making it environmentally friendly.

[0055] In one embodiment, the elastic member (170) may be manufactured by injection molding. Therefore, more stable performance can be provided compared to cases using blow molding, etc. For example, when a bellows-type elastic member (170) is manufactured by blow molding, the thickness of the elastic member (170) may not be formed uniformly. However, in the case of injection molding, such unevenness problem does not occur, so the defect rate is reduced and the asymmetric elasticity problem can also be solved.

[0056] The stem (180) can be coupled to rise and fall together with the piston rod (140). Specifically, when an external force is applied, for example, through the button portion (230), the stem (180) can descend to lower the piston rod (340), and when the external force is removed, the stem (180) can rise by the elastic force of the elastic member (170) to raise the piston rod (140). In one embodiment, the stem (180) can rise and fall together with the piston rod (140) to transfer the contents discharged from the discharge portion of the piston rod (140) to the head portion (200), more specifically, the button portion (230).

[0057] In one embodiment, the upper end of the stem (180) may be formed with a wing portion that protrudes outward along the circumference. The outer surface of the wing portion may extend downward, and a second mounting portion (181) may be formed on the lower surface of the wing portion, on which the upper end of the elastic member (170) is mounted. The second mounting portion (181) supports the upper end of the elastic member (170), and may prevent the elastic member (170) from being dislodged when mounted thereon.

[0058] The head portion (200) detachably connects the pump assembly (100) and the container body (400), and the cap portion (300) is connected thereto, and can discharge contents discharged from the pump assembly (100) to the outside. The head portion (200) according to one embodiment may include a connection portion (210), a housing portion (220), and a button portion (230).

[0059] The connecting portion (210) is coupled to the inner side of the container body (400) by the contents (410), and to the outer side of the housing portion (220). The connecting portion (210) may have a through portion formed on the inner side and a rim portion extending from the inner side to the center. At this time, the through portion may be formed at the center of the rim portion. In addition, a first coupling groove or a first coupling protrusion is formed on the lower inner side of the connecting portion (210) and is coupled with a second coupling protrusion or a second coupling groove formed on the spout portion of the contents (410), thereby coupling the connecting portion (210) and the contents (410). In one embodiment, the rim portion is arranged on the upper surface of the mounting wing of the cylinder (110), so that the cylinder (110) can be mounted on the upper end (e.g., the spout portion) of the contents (410). More specifically, the connecting portion (210) and the contents (410) are coupled, and the rim portion presses the mounting wing of the cylinder (110) downward so that the cylinder (110) can be mounted on the upper end of the contents (410). In addition, a third coupling protrusion protruding outward along the perimeter of the lower outer surface of the connecting portion (210) may be formed. The third coupling protrusion is coupled with a bending portion or a fourth coupling groove formed at the lower end of the housing portion (220), so that the housing portion (220) can be coupled to the outer side of the connecting portion (210).

[0060] In one embodiment, the outer side of the spout of the contents container (410) may be coupled to the inner side of the connecting part (210). A first rotation prevention portion may be formed on the inner surface of the connecting part (210) to prevent rotation with respect to the contents container (410). The first rotation prevention portion may include at least one rotation prevention projection protruding therefrom or at least one rotation prevention groove. At this time, a second rotation prevention portion corresponding to the first rotation prevention portion may be formed on the outer surface of the spout of the contents container (410), and the second rotation prevention portion may include at least one rotation prevention groove or at least one rotation prevention projection. When the connecting part (210) and the contents container (410) are coupled, the first rotation prevention portion and the second rotation prevention portion may be coupled to limit rotation of the connecting part (210) and the contents container (410). For example, the rotation prevention projection of the first rotation prevention part may be combined with the rotation prevention groove of the second rotation prevention part to limit the rotation of the connecting part (210) and the contents (410). However, this rotation prevention structure is merely exemplary, and other structures capable of limiting the rotation of the connecting part (210) and the contents (410) may also be applied.

[0061] In one embodiment, the inner side of the housing part (220) may be coupled to the outer side of the connecting part (210). A third rotation prevention part may be formed on the outer surface of the connecting part (210) to prevent rotation with respect to the housing part (220). The third rotation prevention part may include at least one rotation prevention protrusion protruding therefrom or at least one rotation prevention groove. At this time, a fourth rotation prevention part corresponding to the third rotation prevention part may be formed on the inner surface of the housing part (220), and the fourth rotation prevention part may include at least one rotation prevention groove or at least one rotation prevention protrusion. When the connecting part (210) and the housing part (220) are coupled, the third rotation prevention part and the fourth rotation prevention part may be coupled to limit the rotation of the connecting part (210) and the housing part (220). For example, the rotation prevention projection of the third rotation prevention part may be combined with the rotation prevention groove of the fourth rotation prevention part to limit the rotation of the connecting part (210) and the housing part (220). However, this rotation prevention structure is merely exemplary, and other structures capable of limiting the rotation of the connecting part (210) and the housing part (220) may also be applied.

[0062] According to one embodiment, the connection part (210) may be configured to limit rotation of both the contents (410) and the housing part (220), thereby also limiting rotation of the contents (410) and the housing part (220). According to one embodiment, when the housing part (220) is rotated, the contents (410) may also rotate together and may be vertically coupled or separated from the outer container (420) to provide a structure that facilitates refilling.

[0063] The housing portion (220) can detachably connect the pump assembly (100) and the container body (400). In one embodiment, the housing portion (220) can include a first outer surface and a second outer surface. The first outer surface and the second outer surface can be formed such that a portion of the outer surface protrudes outward by a predetermined length and the protruding edge extends downward.

[0064] The first outer surface may include a first guide protrusion (241) and a second guide protrusion (242) that are formed to be movable along a ramp (412) formed on the inner surface of the outer container (420). In one embodiment, when the inner container (410) is coupled to the pump assembly (100) through the housing portion (220) and rotates with respect to the outer container (420), the first guide protrusion (241) and the second guide protrusion (242) move along the ramp (412) so that the inner container (410) can be vertically coupled or separated from the outer container (420). At this time, when the inner container (410) rotates in the direction in which it is coupled to the outer container (420), the first guide protrusion (241) passes over the first fixing protrusion (411), and the first fixing protrusion (411) is positioned between the first guide protrusion (241) and the second guide protrusion (242), so that the inner container (410) and the outer container (420) can be coupled and fixed. In addition, when the inner container (410) rotates in the direction in which it is separated from the outer container (420), the first guide protrusion (241) passes over the first fixing protrusion (411) and moves along the guide portion, so that the inner container (410) and the outer container (420) can be separated. In one embodiment, the first guide protrusion (241) and the second guide protrusion (242) can be formed to have an angle equal to the inclination angle of the ramp (412). That is, the first guide protrusion (241) and the second guide protrusion (242) can be formed to have a predetermined angle so as to be able to move along the ramp (412).

[0065] In addition, the housing portion (220) can be detachably coupled with the cap portion (300). The housing portion (220) can include at least one second fixing protrusion (251, 252) on the second outer surface for detachably coupling with the cap portion (300) for coupling. The at least one second fixing protrusion (251, 252) can be coupled to a coupling groove (310) formed inwardly along the circumference and spaced apart from the lower end of the cap portion (300) by a predetermined distance.

[0066] In one embodiment, the first outer surface may be formed on the lower side of the second outer surface and may be formed inwardly relative to the second outer surface. According to one embodiment, the first outer surface may be inserted into the interior of the outer container (420), and the lower end of the second outer surface may be seated on the upper inner side of the outer circumference of the outer container (420). Accordingly, when the cap portion (300) and the container body (400) are combined, the outer circumference of the cap portion (300) may be combined so as to be aligned with the outer circumference of the outer container, thereby forming a sense of unity and providing a smooth user experience.

[0067] Furthermore, as described above, the outer side of the connecting part (210) may be coupled to the inner side of the housing part (220). A third rotation prevention part may be formed on the outer surface of the connecting part (210) to prevent rotation with respect to the housing part (220). The third rotation prevention part may have at least one rotation prevention projection protruding therefrom, or may include at least one rotation prevention groove. At this time, a fourth rotation prevention part corresponding to the third rotation prevention part may be formed on the inner surface of the housing part (220), and the fourth rotation prevention part may include at least one rotation prevention groove or at least one rotation prevention projection. When the connecting part (210) and the housing part (220) are coupled, the third rotation prevention part and the fourth rotation prevention part may be coupled to limit the rotation of the connecting part (210) and the housing part (220). For example, the rotation prevention projection of the third rotation prevention part may be combined with the rotation prevention groove of the fourth rotation prevention part to limit the rotation of the connecting part (210) and the housing part (220). However, this rotation prevention structure is merely exemplary, and other structures capable of limiting the rotation of the connecting part (210) and the housing part (220) may also be applied.

[0068] Additionally, a button portion (230) can be coupled to the upper inner side of the housing portion (220).

[0069] The button portion (230) can move up and down when an external force is applied by the user, and transmits the external force to the stem (180). At this time, as the stem (180) moves downward, the elastic member (170) can be compressed. At this time, the compression of the internal air due to the compression of the elastic member (170) can be relieved by the air passage (162). When the user releases the pressure, the elastic member (170) is restored by the elastic force, and the stem (180) can be returned to its original position. At this time, the expansion of the internal air due to the decompression of the elastic member (170) can be relieved by the air passage (162).

[0070] The button portion (230) includes a nozzle portion inside and can discharge contents delivered from the stem (180) to the outside. The button portion (230) is inserted into the housing portion (220) when descending, and the descending can be restricted by the edge portion of the connection portion (210).

[0071] By being coupled to the upper part of the container body (400), contamination of the button part (230) can be prevented and unintended external force can be prevented from being applied to the button part (230). In addition, the cap part (300) can be detachably coupled to the housing part (220). In one embodiment, the cap part (300) can have a coupling groove (310) formed inward along the circumference at a predetermined distance from the lower end. By coupling the coupling groove (310) with at least one second fixing protrusion (251, 252), the cap part (300) can be detachably coupled to the housing part (220).

[0072] In one embodiment, when the cap (300) and the container body (400) are combined, the outer surface of the cap (300) can be combined so as to be aligned with the outer surface of the outer container. Accordingly, a sense of unity can be formed and a smooth user experience can be provided.

[0073] The container body (400) can provide a storage space for accommodating contents. According to one embodiment, the container body (400) can include an inner container (410) and an outer container (420). The inner container (410) is a storage space for accommodating contents, and the outer container (420) can accommodate the inner container.

[0074] The contents contained in the container (410) can be discharged to the outside through the button portion (230) and used by the user. Here, the contents may be, for example, cosmetics (i.e., cosmetics) or medicines, but are not limited thereto, and may include various types or ingredients of materials that can be contained in the container body (400) and discharged through the button portion (230). The formulation of the contents may also be diverse, such as liquid, gel, or powder. In addition, although the container body (400) in the present invention is illustrated as a bottle type, this is merely exemplary, and various types of container bodies (400), such as a tube or a tottle, may be applied.

[0075] In one embodiment, the spout of the container (410) may be coupled to the inside of the connecting portion (210). More specifically, a second coupling protrusion or a second coupling groove formed on the spout of the container (410) may be coupled to a first coupling groove or a first coupling protrusion formed on the lower inner surface of the connecting portion (210), thereby coupling the container (410) and the connecting portion (210). In one embodiment, a ring (130) may be positioned on the upper end (e.g., the spout) of the container (410) so that the settling wing of the cylinder (110) may be settling on the upper end of the container (410). The ring (130) may be omitted, and when the ring (130) is omitted, the settling wing of the cylinder (110) may be directly settling on the upper end of the container (410).

[0076] In addition, in one embodiment, a second rotation prevention portion may be formed on the outer surface of the spout portion of the contents container (410) to prevent rotation with respect to the connection portion (210). The second rotation prevention portion may include at least one rotation prevention groove or at least one rotation prevention projection. At this time, a first rotation prevention portion corresponding to the second rotation prevention portion may be formed on the inner surface of the connection portion (210), and the first rotation prevention portion may have at least one rotation prevention projection protruding therefrom, or may include at least one rotation prevention groove. When the contents container (410) and the connection portion (210) are coupled, the second rotation prevention portion and the first rotation prevention portion may be coupled to limit rotation of the contents container (410) and the connection portion (210). For example, the rotation prevention projection of the first rotation prevention portion may be coupled with the rotation prevention groove of the second rotation prevention portion to limit rotation of the contents container (410) and the connection portion (210). However, this anti-rotation structure is merely exemplary, and other structures capable of limiting the rotation of the content member (410) and the connecting portion (210) may be applied.

[0077] In one embodiment, the outer container (420) may include a guide portion including a ramp (412) formed from the top downward on the inner surface. In one embodiment, the guide portion may further include a sliding surface extending in connection with the ramp and a support portion formed upwardly spaced apart from the sliding surface by a predetermined distance. At this time, the angle formed by the sliding surface with the upper end of the outer container (420) may be smaller than the inclination angle of the ramp (412). In addition, the support portion may be formed along the inner circumference of the outer container (420) by a predetermined length. Furthermore, the support portion may be formed to be parallel to the sliding surface. According to one embodiment, the first guide protrusion (241) and the second guide protrusion (242) of the housing portion (220) may be caught on the lower end of the support portion to prevent the inner container (410) from being separated upward from the outer container (420). Additionally, the outer container (420) may include a first fixing protrusion (411) formed at a predetermined distance from the end of the guide portion. At this time, the first fixing protrusion (411) may be formed to extend upward from the sliding surface to the support portion.

[0078] In one embodiment, when the contents (410) is coupled to the pump assembly (100) through the housing portion (220) and rotates relative to the outer container (420), the first guide protrusion (241) and the second guide protrusion (242) move along the ramp (412) so that the contents (410) can be coupled or separated from the outer container (420) in the vertical direction. At this time, when the contents (410) rotates in the direction in which it is coupled to the outer container (420), the first guide protrusion (241) passes over the first fixing protrusion (411) so that the first fixing protrusion (411) is positioned between the first guide protrusion (241) and the second guide protrusion (242), so that the contents (410) and the outer container (420) can be coupled and fixed. In addition, when the contents (410) rotates in the direction of separation from the outer container (420), the contents (410) and the outer container (420) can be separated by the first guide protrusion (241) passing over the first fixed protrusion (411) and moving along the guide portion.

[0079] In one embodiment, at least one guide portion, a support portion, and a first fixing protrusion (411) may be provided, and the first guide protrusion (241) and the second guide protrusion (242) may be formed to correspond to the guide portion, the support portion, and the first fixing protrusion (411).

[0080] In one embodiment, when all the contents contained in the inner container (41) are used up, the user can separate the inner container (410) from the outer container (420) and refill and use a new inner container (410) filled with contents. In this case, only the inner container (410) is exchanged and used, and the outer container (420) can be used repeatedly, thereby reducing environmental pollution, and the user can purchase and use only a new inner container (410) at a low price.
