Description

[Technical field]

[0001] The present invention relates to a content container whose head portion rises and falls by rotation, which allows the inner container to be easily removed from and replaced with an outer container, and which has an improved pressure limiting structure. [Background technology]

[0002] The content container has a wide variety of structures depending on the dosage form, usage method, etc. For example, in the case of a content having a dosage form of liquid, gel, or cream, it can be contained in a pump container that expels the content to the outside by pressing.

[0003] Such pump containers are generally composed of a container portion for accommodating the contents, a pump assembly that is compressed and released by pressure to move the contents, and a head portion that presses the pump assembly to expel the contents to the outside. However, such pump containers often have a problem in that the head portion is pressed unintentionally to expel the contents, and there is a problem in that the design of the container is limited because the head portion is always exposed to the outside.

[0004] In order to solve the problems of the pump container, a container in which the head part rises and falls by rotation has been developed. However, such a rise-type container has a problem that when a specific area of ​​the head part is pressed, the head part partially descends even though the pressing is limited, causing a part of the contents to be discharged. In addition, because the structure of the rise-type container is complicated, it is difficult to apply a structure that allows the inner container to be replaced, and even if a replacement structure is applied, the operation process for replacing the inner container is complicated, and the assembly process is complicated, which leads to a problem of reduced productivity. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been devised to solve the above problems, and its object is to provide a content container in which the head portion rises and falls by rotation, the inner container can be easily removed from and replaced with an outer container, and the pressure limiting structure is improved.

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

[0007] According to an embodiment of the present invention, there is provided a content container comprising: an inner container assembly for containing a content and discharging the content to the outside by pressing; and an outer container assembly for containing the inner container assembly, wherein the outer container assembly may comprise: an outer container arranged to enclose at least a part of the inner container assembly; a connection part for connecting the outer container and the inner container assembly, the connection part moving up and down along the outer container when rotating to raise and lower the inner container assembly; and a rotation part for raising and lowering the connection part by a rotation operation.

[0008] In addition, the inner container assembly may have a top surface located at a height corresponding to a top surface of the outer container assembly, and when the rotating part rotates, the top surface may protrude above the outer container assembly.

[0009] Furthermore, a wing portion may be protruding along the outer peripheral surface of the upper end of the inner container assembly, and a first limiting protrusion contacting the lower end of the wing portion may be protruding along the inner peripheral surface of the upper end of the rotating portion.

[0010] Furthermore, the wing portion may be formed so as to be inclined downwardly and inwardly.

[0011] Furthermore, the inner container assembly may include a nozzle portion for discharging the contents, the nozzle portion being formed so as to be inclined inwardly and downwardly at an angle corresponding to the blade portions.

[0012] Furthermore, the outer container may be provided with at least one first guide groove, the rotating portion may be provided with at least one second guide groove, and the connecting portion may be provided with at least one guide protrusion that is fitted into the first guide groove and the second guide groove.

[0013] Furthermore, when the rotating part rotates, the guide protrusion may move along the first guide groove and the second guide groove, and the connecting part may rise and fall along the outer container.

[0014] Furthermore, the first guide groove may be formed in a spiral direction relative to a cross section of the outer container, and the second guide groove may be formed in a perpendicular direction relative to a cross section of the rotating portion.

[0015] Furthermore, the inner container assembly may include an inner container for accommodating the contents, a pump assembly for moving the contents when pressed, and a head portion for discharging the contents to the outside.

[0016] Furthermore, a stopper may be provided between the head portion and the pump assembly to prevent the head portion from being pressed.

[0017] Furthermore, the pump assembly may include a pump portion that is compressed and decompressed by pressure to move the contents, and an undercap that connects the pump portion to the outer container assembly.

[0018] Furthermore, an undercut may be formed on the outside of the undercap, the undercut being in contact with one side of the connecting portion.

[0019] Furthermore, the undercut may be grasped to remove the inner container assembly from the outer container assembly.

[0020] Additionally, the entire inner container assembly may be made of the same material. Effect of the Invention

[0021] According to the present invention, the inner container assembly is easily removed from the outer container by being raised and lowered by rotation. Therefore, the entire inner container assembly can be replaced with a new inner container assembly while holding the outer container assembly, so that the contents can be easily replaced and the outer container assembly can be reused. If the inner container assembly is made of the same material as a whole, the inner container assembly can be easily separated and discharged, which is advantageous in that it is convenient to recycle.

[0022] Furthermore, according to the present invention, when the head portion is lowered and pressure is restricted, the descent is restricted regardless of which area of ​​the head portion is pressed, thereby eliminating the problem of the head portion being partially pressed and the contents being expelled.

[0023] Furthermore, according to the present invention, the head portion is not exposed during the assembly and transportation processes, thereby preventing unnecessary interference and damage to the head portion.

[0024] Furthermore, according to the present invention, the inner container assembly and the outer container assembly can be joined regardless of their relative rotational positions, and such a non-directional fastening structure simplifies the production and assembly processes of the product. It also makes replacement of the inner container assembly convenient since it is no longer necessary to precisely align the relative rotational positions of the inner container assembly and the outer container assembly during the process of replacing the inner container assembly.

[0032] Referring to FIGS. 1-6, the content container 1000 may include an inner container assembly 100 and an outer container assembly 200.

[0033] The inner container assembly 100 can accommodate contents and expel the contents to the outside by pressing. The inner container assembly 100 can be raised and lowered along the outer container assembly 200. By raising and lowering the inner container assembly 100 along the outer container assembly 200, pressing of the inner container assembly 100 can be made possible or pressing of the inner container assembly 100 can be limited. Furthermore, the inner container assembly 100 can be entirely removed from the outer container assembly 200 by raising and lowering. This allows the entire inner container assembly 100 to be replaced with a new inner container assembly 100 while holding the outer container assembly 200, making it possible to easily replace the inner container assembly 100.

[0034] Depending on the embodiment, the inner container assembly 100 may be formed entirely from the same or similar materials. For example, the inner container assembly 100 may be formed entirely from plastic materials and may not include metal materials. In this case, the plastic materials include a wide variety of plastic materials such as polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyketone (POK), polyether ether ketone (PEEK), polycarbonate (PC), polyoxymethylene (POM), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), etc., and the present invention is not limited thereto, and includes all known plastic materials. In this case, the inner container assembly 100 can be easily separated and discharged after being removed from the outer container assembly 200, which contributes to environmental protection and increases the recycling rate and the reuse rate of the package.

[0035] Depending on the embodiment, the inner container assembly 100 can be inserted into the outer container assembly 200 (see FIG. 1(a)) or protrude out of the outer container assembly 200 (see FIG. 1(b)) by being raised and lowered. Specifically, for example, the inner container assembly 100 can be positioned at a height corresponding to the top surface of the outer container assembly 200, and the top surface can protrude above the outer container assembly 200 (as the rotating part 230 rotates). In this case, for example, when the inner container assembly 100 is inserted into the outer container assembly 200, it is possible to prevent the inner container assembly 100 from being pressed, and when the inner container assembly 100 protrudes out of the outer container assembly 200, it is possible to allow the inner container assembly 100 to be pressed.

[0036] Depending on the embodiment, when the inner container assembly 100 protrudes outside the outer container assembly 200, the inner container assembly 100 and the outer container assembly 200 can be separated from each other by pressing the inner container assembly 100 upward or pressing the outer container assembly 200 downward. In this case, the inner container assembly 100 whose contents have been used up can be easily replaced with a new inner container assembly 100.

[0037] Depending on the embodiment, the inner container assembly 100 may include an inner container 110, a pump assembly 120, and a head portion .

[0038] The inner container 110 can contain contents. In this case, the contents include, for example, liquid, gel, or powder cosmetics, medicines, quasi-drugs, etc. For example, the contents include lotion, milk lotion, moisture lotion, nutritional lotion, skin lotion, skin softener, skin toner, astringent, massage cream, nutritional cream, moisture cream, whitening essence, tone-up cream, UV protection agent, sunscreen cream, sunscreen milk, BB cream, makeup base, foundation, CC cream, concealer, blush, shading, eyeshadow, eyebrow, eye cream, primer, etc., but are not limited to these.

[0039] Depending on the embodiment, the inner container 110 may be formed in a cylindrical bottle shape, but is not limited thereto, and a wide variety of embodiments are applicable, such as a tube, a jar, a dispenser, a compact, etc.

[0040] The pump assembly 120 can move the contents by being pressed. For example, the pump assembly 120 is coupled to the inner container 110 to move the contents accommodated in the inner container. For example, the pump assembly 120 is coupled to the outer container assembly 200 to be raised and lowered by the outer container assembly 200. When the pump assembly 120 is raised and lowered, the inner container 110 and the head portion 130 are raised and lowered together, so that the inner container assembly 100 can be raised and lowered as a whole. The pump assembly 120 and the inner container 110 and the pump assembly 120 and the outer container assembly 200 can be connected by a wide variety of known connection methods such as screwing, fitting, hooking, fitting, and engagement.

[0041] Depending on the embodiment, the pump assembly 120 may include a pump portion 121 and an undercap 122 .

[0042] The pump unit 121 can move the contents by being compressed and decompressed by pressing. For example, the pump unit 121 may include a cylinder with upper and lower openings and a hollow space formed inside, a seal part at least partially inserted into the cylinder to at least partially seal the upper part of the cylinder, a seal cap that moves up and down in close contact with the cylinder inside the cylinder, a piston rod surrounded by the seal cap and moving up and down relative to the cylinder, a stem connected to the piston rod and moving up and down with the piston rod, and an elastic member disposed between the seal part and the stem to provide an elastic force from the seal part to the stem. However, the present invention is not limited thereto, and the pump unit 121 may have any type of known pump structure, such as an airless type, a dip tube type, a spray type, etc.

[0043] Depending on the embodiment, the elastic member constituting the pump portion 121 may be a bellows-type spring having repeated peaks and valleys, or may be a spring with a sealed side. In this case, a stem blade may be formed on the outside of the upper end of the stem to support the upper end of the elastic member, and a downward bent portion may be formed on the lower side of the outer end of the stem blade to support the side of the elastic member. In addition, a support groove may be formed on the top surface of the seal portion, into which the lower end of the elastic member is inserted to support the lower end and side of the elastic member. In addition, at least one of the stem blade and the seal portion may be formed with at least one air passage to eliminate changes in internal pressure when the elastic member is compressed and released.

[0044] Depending on the embodiment, the pump portion 121 may be formed entirely from the same or similar material. For example, the pump portion 121 may be formed entirely from a plastic material and may not include a metal material. In particular, the elastic member included in the pump portion 121 may also be formed from a plastic material rather than a metal material. In this case, when the inner-container assembly 100 is disposed of, it is not necessary to remove and dispose of only the pump portion 121, which can increase the recycling rate and the package reuse rate.

[0045] The undercap 122 can connect the pump portion 121 to the outer container assembly 200. For example, the undercap 122 can be coupled to the inner container 110 and / or the pump portion 121 on the inside, and can be coupled to the outer container assembly 200 (particularly, the connection portion 220) on the outside.

[0046] Depending on the embodiment, the undercap 122 can restrict the pump assembly 120 from descending from at least a part (particularly, the connection part 220) of the outer container assembly 200 while the pump assembly 120 and the outer container assembly 200 are coupled together, but can allow the pump assembly 120 to rise. This allows the inner container assembly 100 to rise by the outer container assembly 200 (particularly, the connection part 220) when the outer container assembly 200 (particularly, the rotating part 230) is rotated, and thereafter, the inner container assembly 100 and the outer container assembly 200 can be separated from each other by pressing the inner container assembly 100 upward or pressing the outer container assembly 200 downward.

[0047] For this purpose, for example, an undercut 122-1 can be provided protruding from the undercap 122. The undercut 122-1 can be in contact with, for example, one side of the outer container assembly 200 (particularly, the inner upper end of the connection part 220). As a result, when at least a part of the outer container assembly 200 (particularly, the connection part 220) rises (by rotation of the rotating part 230), one side of the outer container assembly 200 (particularly, the upper end of the first region 221 of the connection part 220) presses the undercut 122-1, and the undercap 122 can rise together. Due to the rise of the undercap 122 in this manner, the inner container assembly 100 can rise as a whole. In addition, when the undercap 122 is raised and the inner container assembly 100 is pressed upward or the outer container assembly 200 is pressed downward, the rise of the undercut 122-1 is not restricted, so the outer container assembly 200 rises and can be removed from the inner container assembly 100.

[0048] Depending on the embodiment, the undercut 122-1 may be fitted into one side of the outer container assembly 200 (particularly, the connection portion 220) to couple the undercap 122 to the outer container assembly 200 (particularly, the connection portion 220). However, the present invention is not limited to such a coupling method, and for example, at least one coupling groove (not shown) may be formed on the outer peripheral surface of the undercap 122, particularly on the underside of the undercut 122-1 in the undercap 122, through which the undercap 122 may be coupled to the outer container assembly 200 (particularly, the connection portion 220). In addition to these, a wide variety of known coupling methods such as screwing, hooking, and engagement may be applied, and a plurality of coupling methods may be applied simultaneously.

[0049] Depending on the embodiment, at least one gripping portion may be formed on the outside of the undercap 122. When removing the inner container assembly 100, the user can grip the gripping portion. For example, the undercut 122-1 may function as the gripping portion. That is, the user can remove the inner container assembly 100 from the outer container assembly 200 by gripping the undercut 122-1 and pressing the inner container assembly 100 upward or pressing the outer container assembly 200 downward. Depending on the embodiment, a fitting groove formed on the outside of the undercap 122 may function as the gripping portion, or at least one gripping protrusion may be provided on the outside of the undercap 122 as the gripping portion. In addition to these, various other components that can be gripped by the user may be additionally / alternatively applied.

[0050] The head unit 130 may press the pump assembly 120 to discharge the contents to the outside. Specifically, the head unit 130 may press the pump assembly 120 by receiving a pressure from a user, and the contents moved by the pump assembly 120 may flow into the head unit 130 through, for example, an inlet hole 131 and then be discharged to the outside through a nozzle unit 132.

[0051] Depending on the embodiment, the head portion 130 may be formed with wing portions 133. The wing portions 133 contact at least a portion of the outer container assembly 200 (particularly, the first limiting protrusion 232) and limit the downward movement of the head portion 130, thereby limiting the pressing of the head portion 130. For example, the wing portions 133 may protrude outward from the upper end of the head portion 130, but the present invention is not limited thereto, and the wing portions 133 may be formed at a variety of positions on the head portion 130.

[0052] Depending on the embodiment, the wing portion 133 can be formed continuously along the periphery of the head portion 130. In this case, the entire area along the periphery of the head portion 130 comes into contact with one side of the outer container assembly 200 (particularly the first limiting protrusion 232), and the head portion 130 cannot descend no matter what part is pressed. In other words, when a specific part of the head portion 130 is pressed in the pressing-limited state, the problem of the head portion 130 partially descending can be eliminated.

[0053] Depending on the embodiment, the wing portion 133 may be formed to be inclined downward inward. This inclined structure minimizes friction between the wing portion 133 and the outer container assembly 200 (particularly the rotating portion 230) during the process of raising and lowering the head portion 130. The reduction in frictional force makes the inner container assembly 100 rise and fall more naturally, improving the feeling of use.

[0054] Depending on the embodiment, the nozzle portion 132 may be formed to be inclined downward inward at an angle corresponding to the wing portion 133. In this case, when the inner container assembly 100 is fully inserted into the outer container assembly 200 and the wing portion 133 comes into contact with one side of the outer container assembly 200 (particularly, the first limiting protrusion 232), the nozzle portion 132 can also come into contact with one side of the outer container assembly 200 (particularly, the first limiting protrusion 232) together with the wing portion 133, and the outer container assembly 200 does not need to have a fitting portion for fitting the nozzle portion 132. With this structure, when the inner container assembly 100 and the outer container assembly 200 are fastened together, the wing portion 133 and the nozzle portion 132 always come into contact with one side of the outer container assembly 200 (particularly, the first limiting protrusion 232) at the same time, so that the position of the nozzle portion 132 does not affect the insertion depth of the inner container assembly 100. That is, a non-directional fastening structure can be applied to the inner container assembly 100 and the outer container assembly 200.

[0055] Depending on the embodiment, at least one second limiting protrusion 134 can be provided on the inside of the head portion 130. The second limiting protrusion 134 can guide the elevation path of the head portion 130 and limit the pressing force of the head portion 130.

[0056] In one embodiment, the second limiting protrusion 134 can guide the lifting path of the head unit 130. In this case, the pump assembly 120, particularly the undercap 122, can be formed with a first moving groove 122-2 that forms the lifting path of the second limiting protrusion 134 (see FIG. 6(a)). The first moving groove 122-2 may be perpendicular to the cross section of the pump assembly 120, but the present invention is not limited thereto. In this case, when the head unit 130 is pressed, the second limiting protrusion 134 moves along the first moving groove 122-2, and the lifting path of the head unit 130 can be guided.

[0057] In another embodiment, the second limiting protrusion 134 can limit the pressing force of the head part 130. More specifically, the head part 130 is rotated to change the position of the second limiting protrusion 134, thereby making it possible to adjust whether or not the pressing force of the head part 130 is limited. In this case, the pump assembly 120', particularly the undercap 122', can be provided with a first moving groove 122-2 forming a lifting path of the second limiting protrusion 134 and a second moving groove 122-3 forming a rotation path of the second limiting protrusion 134 (see FIG. 6(b)). In this case, the first moving groove 122-2 may be perpendicular to the cross section of the pump assembly 120, and the second moving groove 122-3 may be parallel to the cross section of the pump assembly 120, but the present invention is not limited thereto. When the second limiting protrusion 134 is located at the upper part of the first moving groove 122-2, the pressing of the head part 130 is permitted, and when the second limiting protrusion 134 is located at the upper part of the second moving groove 122-3, the pressing of the head part 130 is restricted. Accordingly, the pressing of the head part 130 can be permitted in a first rotation range with respect to the pump assembly 120', and the pressing of the head part 130 can be restricted in a second rotation range. More specifically, when the head part 130 is in the first rotation range, the second limiting protrusion 134 can rise and fall along the first moving groove 122-2, and the descent of the head part 130 is permitted, and the pressing of the head part 130 can be permitted. Also, when the head part 130 is in the second rotation range, the lower end of the second limiting protrusion 134 comes into contact with the lower end of the second moving groove 122-3, and the descent of the head part 130 is restricted, and the pressing of the head part 130 can be restricted. That is, by having the head portion 130 in the second rotation range, it is possible to prevent the discharge of the contents due to unintentional pressing of the head portion 130.

[0058] Depending on the embodiment, pressing of the head portion 130 may be limited before the first use of the inner container assembly 100. For this purpose, a stopper 140 may be provided between the head portion 130 and the pump assembly 120. The stopper 140 contacts the lower end of the head portion 130 and one side of the pump assembly 120 (particularly, the upper end of the undercut 122-1), respectively, and can prevent unintentional pressing of the head portion 130. The stopper 140 may be attached, for example, when the inner container assembly 100 is initially disposed, and removed immediately before the inner container assembly 100 is coupled to the outer container assembly 200.

[0059] Depending on the embodiment, when a stopper 140 is provided between the head portion 130 and the inner container 110, the second moving groove 122-3 may not be provided, and vice versa is also applicable, but the present invention is not limited to this in any way, and a wide variety of embodiments are applicable, such as providing both.

[0060] The outer container assembly 200 can house the inner container assembly 100 therein. In addition, the outer container assembly 200 can raise and lower the inner container assembly 100 while at least a portion of the outer container assembly 200 rotates.

[0061] Depending on the embodiment, the outer container assembly 200 may include an outer container 210 , a connecting portion 220 , and a rotating portion 230 .

[0062] The outer container 210 can be arranged to enclose at least a part of the inner container assembly 100, particularly at least a part of the inner container 110. This can protect the inner container 110 from external impact and improve the thermal insulation of the inner container 110.

[0063] The connection part 220 can connect the outer container 210 and the inner container assembly 100. For example, the connection part 220 can connect the outer container 210 and the inner container assembly 100 by connecting the inner container 210 to the undercap 122 of the pump assembly 120 on the inside and connecting to the outer container 210 on the outside. Also, the connection part 220 can rise and fall along the outer container 210 (when the rotating part 230 rotates). The pump assembly 120 connected to the connection part 220 can rise and fall together by the rise and fall of the connection part 220. That is, the inner container assembly 100 can rise and fall by the rise and fall of the connection part 220.

[0064] Depending on the embodiment, the connecting portion 220 may have a lower first region 221 that protrudes inward compared to an upper second region 222. In this case, an upper end of the first region 221 may contact a lower end of the undercut 122-1.

[0065] Depending on the embodiment, at least one locking protrusion 222-1 may be formed on the inside of the connection part 220, particularly on the inside of the second region 222. In this case, the undercut 122-1 may have a lower end in contact with the upper end of the first region and an upper end in contact with the locking protrusion 222-1, through which the connection part 220 and the inner-container assembly 100 may be coupled. At this time, the locking protrusion 222-1 may be elastically deformed outward due to the action of an external force. For example, when an external force is applied to the locking protrusion 222-1 while the undercut 122-1 is pressed upward, the locking protrusion 222-1 is elastically deformed outward, thereby allowing the undercut 122-1 to rise. That is, the descent of the undercut 122-1 is restricted by the first region, but the rise of the undercut 122-1 may be partially permitted by the elastic deformation of the locking protrusion 222-1. With this structure, when the rotating part 230 is rotated, the undercut 122-1 rises due to the connecting part 220, and the inner container assembly 100 can be lifted from the outer container assembly 200. Thereafter, if the inner container assembly 100 is pressed upward or the outer container assembly 200 is pressed downward, the locking projection 222-1 is elastically deformed and the undercut 122-1 rises, making it possible for the inner container assembly 100 and the outer container assembly 200 to be separated from each other.

[0066] Depending on the embodiment, in order to couple the connecting portion 220 to the undercap 122, the connecting portion 220 may be formed with at least one fitting protrusion (not shown) that is fitted into a fitting groove of the undercap 122. However, the present invention is not limited to such a coupling method, and various other coupling methods such as screwing and hooking may be applied.

[0067] The rotating part 230 can raise and lower the inner container assembly 100 while rotating in response to a rotation operation by the user. Specifically, the rotating part 230 can raise and lower the connection part 220 in response to a rotation operation, thereby raising and lowering the inner container assembly 100 connected to the connection part 220. For example, the rotating part 230 is coupled to the outside of the outer container 210 and / or the connection part 220, and can raise and lower the connection part 220 in response to the rotation operation of the user.

[0068] Depending on the embodiment, the outer container 210 may be provided with at least one first guide groove 211, the rotating part 230 may be provided with at least one second guide groove 231, and the connecting part 220 may be provided with at least one guide protrusion 221-1 that is fitted into the first guide groove 211 and the second guide groove 231. When the rotating part 230 rotates, the guide protrusion 221-1 moves along the first guide groove 211 and the second guide groove 231, so that the connecting part 220 can move up and down along the outer container 210. More specifically, when the rotating part 230 rotates, the second guide groove 231 rotates and presses the guide protrusion 221-1 in the rotation direction to rotate the guide protrusion 221-1, so that the guide protrusion 221-1 can move along the first guide groove 211. When the guide protrusion 221 - 1 moves along the first guide groove 211 , the connection part 220 can move up and down along the outer container 210 .

[0069] Depending on the embodiment, the first guide groove 211 may be formed in a spiral direction with respect to the cross section of the outer container 210, and the second guide groove 231 may be formed in a vertical direction with respect to the cross section of the rotating part 230. In this case, when the rotating part 230 rotates, the guide protrusion 221-1 moves in a spiral direction along the first guide groove 211, so that the connecting part 220 and the inner container assembly 100 can rotate and move up and down. However, the present invention is not limited thereto, and various other embodiments are applicable, such as the first guide groove 211 being formed in a vertical direction and the second guide groove 231 being formed in a spiral direction.

[0070] Depending on the embodiment, a first limiting protrusion 232 can be provided protruding inwardly along the inner peripheral surface of the upper end of the rotating part 230. The first limiting protrusion 232 can contact at least a part of the inner container assembly 100, in particular the lower end of the wing part 133 of the head part 130. This makes it possible to prevent the inner container assembly 100 from being pressed when the top surface of the inner container assembly 100 is located at a height corresponding to the top surface of the outer container assembly 200.

[0071] Depending on the embodiment, the first limiting protrusion 232 is formed along the inner circumferential surface of the upper end of the rotating part 230, so that it can come into contact with the wing parts 133 as a whole. As a result, when the top surface of the inner container assembly 100 is located at a height corresponding to the top surface of the outer container assembly 200 and the first limiting protrusion 232 and the wing parts 133 come into contact with each other, it becomes possible for the first limiting protrusion 232 and the wing parts 133 to limit the pressing of the head part 130 regardless of which region of the head part 130 is pressed.

[0072] Depending on the embodiment, the first limiting protrusion 232 may protrude vertically from the inner circumferential surface of the rotating part 230 without forming an incline, or may be formed to be inclined downward inwardly in correspondence with the blade part 133 and / or the nozzle part 132. Regardless of the shape, the first limiting protrusion 232 can contact one side of the blade part 133 and / or the nozzle part 132 to prevent the head part 130 from being pressed.

[0073] Depending on the embodiment, a fitting portion (not shown) may be formed in one region of the first limiting protrusion 232. For example, the fitting portion may be formed by vertically penetrating one region of the first limiting protrusion 232 or by recessing downward, and the nozzle portion 132 of the inner container assembly 100 may be fitted into the fitting portion.

[0074] Depending on the embodiment, a region of the first limiting protrusion 232 may not have a fitting portion. In this case, for example, the first limiting protrusion 232 may be formed as the entire inner circumferential surface of the upper end of the rotating part 230 and may be connected without interruption. The first limiting protrusion 232 contacts the blade part 133 and the nozzle part 132 as a whole, and can prevent both the blade part 133 and the nozzle part 132 from descending. Such prevention of the descending is performed regardless of the relative rotational position between the head part 130 and the rotating part 230, and thus a non-directional fastening structure between the head part 130 and the rotating part 230, i.e., a non-directional fastening structure between the inner container assembly 100 and the outer container assembly 200, can be achieved. This non-directional fastening structure simplifies the production and assembly processes of the product and makes replacement convenient since it eliminates the need to precisely align the relative rotational positions of the inner container assembly 100 and the outer container assembly 200 during the process of replacing the inner container assembly 100.

[0075] The content container 1000 of FIGS. 1-6 is merely exemplary and many different configurations are possible depending on the embodiment to which the present invention is applied.

[0076] FIG. 7 is a diagram for explaining a non-directional fastening structure according to an embodiment of the present invention.

[0077] 7, when the inner container assembly 100 is inserted into the outer container assembly 200, the blades 133 protruding outward from the upper end of the head portion 130 come into contact with the first limiting protrusions 232 protruding from the inner circumferential surface of the rotating portion 230. At this time, the blades 133 are formed so as to be inclined downward inward, and at the same time, the nozzle portion 132 can also be formed so as to be inclined downward inward at an angle corresponding to the blades 133. In this case, when the blades 133 come into contact with the first limiting protrusions 232, the nozzle portion 132 can also come into contact with the first limiting protrusions 232 in a similar manner, and therefore the first limiting protrusions 232 do not need to be formed with an insertion portion into which the nozzle portion 132 is inserted.

[0078] As a result, when the inner container assembly 100 is inserted into the outer container assembly 200 in a state in which the inner container assembly 100 is removed from the outer container assembly 200, the wing portion 133 and the nozzle portion 132 always come into contact with the first limiting protrusion 232 at the same time, so that the position of the nozzle portion 132 does not affect the insertion depth of the inner container assembly 100 and / or whether or not the first limiting protrusion 232 prevents the inner container assembly 100 from descending. That is, a non-directional fastening structure can be applied to the inner container assembly 100 and the outer container assembly 200. Such a non-directional fastening structure eliminates the need to precisely align the relative rotational positions of the inner container assembly 100 and the outer container assembly 200 during the production and assembly process of the product and the process of replacing the inner container assembly 100, thereby increasing productivity and making replacement easier.

[0079] The non-directional fastening structure of FIG. 7 is merely exemplary, and a wide variety of configurations are possible depending on the embodiment of the present invention.

[0080] 8 is a diagram for explaining the protruding operation of the head portion according to the embodiment of the present invention. In order to show the internal structure, the rotating portion 230 is shown by a two-dot chain line.

[0081] 8, when the rotating part 230 rotates, the second guide groove 231 formed in a direction perpendicular to the cross section of the rotating part 230 rotates and presses the guide protrusion 221-1 in the rotation direction. As a result, the guide protrusion 221-1 can move along the first guide groove 211 formed in a spiral direction with respect to the cross section of the outer container 210. As the guide protrusion 221-1 moves along the first guide groove 211, the connecting part 220 can rotate and ascend and descend along the outer container 210. As the connecting part 220 ascends and descends, the inner container assembly 100 coupled with the connecting part 220 can also ascend and descend, and thus the head part 130 can protrude from the outer container assembly 200 or be inserted into the outer container assembly 200.

[0082] The protruding operation of the head portion in FIG. 8 is merely exemplary, and various methods can be applied depending on the embodiment to which the present invention is applied.

[0083] FIG. 9 is a diagram for explaining an overall method of using the content container according to the embodiment of the present invention.

[0084] 9, when the rotating part 230 is rotated in one direction, the connecting part 220 is raised by the rotating part 230, and thus the pump assembly 120 coupled with the connecting part 220 is raised, and the inner container assembly 100 may be raised. In this case, the inner container assembly 100 may protrude outward from the outer container assembly 200, and the restriction on the pressing of the head part 130 by the first limiting protrusion 232 may be released. A user may compress the pump assembly 120 by pressing the head part 130, thereby discharging the contents to the outside of the nozzle part 132.

[0085] Thereafter, when the inner container assembly 100 is pushed upward or the outer container assembly 200 is pushed downward in a state where the inner container assembly 100 protrudes outside the outer container assembly 200, the inner container assembly 100 and the outer container assembly 200 can be separated from each other. At this time, the user can more easily separate the inner container assembly 100 and the outer container assembly 200 by gripping the undercut 122-1 of the inner container assembly 100. In this way, while holding the outer container assembly 200, only the inner container assembly 100 whose contents have been used up can be easily replaced with a new inner container assembly 100, thereby making it easy to replace the inner container assembly 100.

[0086] The usage scheme according to FIG. 9 is merely exemplary, and a wide variety of schemes are applicable depending on the embodiment to which the present invention is applied.

[0087] The drawings and the specification disclose the best mode for carrying out the present invention.
