Description

Technical Field

[0001] The present invention relates to a content container in which a head portion moves up and down by rotation, and relates to a content container that can easily remove and replace an inner container from an outer container and in which a pressing restriction structure is improved.

Background Art

[0002] Content containers have various structures depending on the dosage form of the content to be contained, the usage method, and the like. For example, in the case of a content having a liquid, gel-like, or cream-like dosage form, it can be contained in a pump container that discharges the content to the outside by pressing.

[0003] Such a pump container is usually composed of a container portion that contains the content, a pump assembly that is compressed and decompressed by pressing to move the content, and a head portion that presses the pump assembly to discharge the content to the outside. However, in the case of such a pump container, there is a frequent problem that the head portion is pressed and the content is discharged even when the user does not intend it, and there is also a problem that there is a limitation in the design of the container because the head portion is always exposed to the outside.

[0004] In order to solve the problems of such a pump container, a container in which the head portion moves up and down by rotation has been developed. However, in the case of such a lifting type container, when a specific area of the head portion is pressed, although it is in a pressing restricted state, there is a problem that a part of the content is discharged due to the partial lowering of the head portion. In addition, since the lifting type container has a complicated structure, it is difficult to apply a structure in which the inner container can be replaced. Even if a replacement configuration is applied, the operation process for replacing the inner container is complicated, and moreover, the assembly process is complicated, which leads to a problem of reduced productivity.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention was devised to solve the above problems, and aims to provide a container in which the head portion moves up and down by rotation, the inner container can be easily removed from and replaced with the outer container, and moreover, the pressure limiting structure has been improved.

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

[0007] An embodiment of the present invention provides a contents container. The contents container comprises an inner container assembly that contains contents and discharges the contents to the outside by pressing, and an outer container assembly that houses the inner container assembly, wherein the outer container assembly may include an outer container that is arranged to enclose at least a part of the inner container assembly, a connecting part that connects the outer container and the inner container assembly and moves up and down along the outer container when rotated to move the inner container assembly up and down, and a rotating part that moves the connecting part up and down by rotational operation.

[0008] Furthermore, the top surface of the inner container assembly may be positioned at a height corresponding to the 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 provided along the outer circumferential surface of the upper end of the inner container assembly, and a first limiting projection may be provided along the inner circumferential surface of the upper end of the rotating portion, in contact with the lower end of the wing portion.

[0010] Furthermore, the wing portion may be formed to be inclined downward and inward.

[0011] Furthermore, the inner container assembly may also include a nozzle portion for discharging the contents, and the nozzle portion may be formed to be inclined inward and downward at an angle corresponding to the fin portion.

[0012] Furthermore, the outer container may be provided with at least one first guide groove, the rotating part may be provided with at least one second guide groove, and the connecting part may be provided with at least one guide projection that fits into the first guide groove and the second guide groove.

[0013] Furthermore, when the rotating part rotates, the guide projection may move along the first guide groove and the second guide groove, causing the connecting part to move up and down along the outer container.

[0014] Furthermore, the first guide groove may be formed in a helical direction with respect to the cross-section of the outer container, and the second guide groove may be formed perpendicular to the cross-section of the rotating part.

[0015] Furthermore, the inner container assembly may also include an inner container for containing the contents, a pump assembly for moving the contents by pressing, 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 also include a pump section that is compressed and decompressed by pressing to move the contents, and an undercap that connects the pump section to the outer container assembly.

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

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

[0020] In addition to these, the inner container assembly may be formed from the same material as a whole. [Effects of the Invention]

[0021] According to the present invention, by raising and lowering the inner container assembly by rotation, it is easy to remove the inner container assembly from the outer container. Therefore, while holding the outer container assembly, the entire inner container assembly can be replaced with a new inner container assembly and used, so that the replacement of the contents can be easily performed, and moreover, the outer container assembly can be reused. When the inner container assembly is formed of the same material as a whole, the inner container assembly can be easily separated and discharged, so there is an advantage that recycling is convenient.

[0022] Further, according to the present invention, in a state where the head portion descends and the pressing is restricted, no matter which region of the head portion is pressed, the descent is restricted. As a result, it is possible to solve the problem that the head portion is partially pressed and the contents are discharged.

[0023] Furthermore, according to the present invention, by preventing the head portion from being exposed during the processes of assembly and transportation, unnecessary interference and damage to the head portion can be prevented.

[0024] Furthermore, according to the present invention, the inner container assembly and the outer container assembly can be coupled regardless of their relative rotational positions to each other. Such a non-directional fastening structure simplifies the production and assembly processes of the product, and eliminates the need to highly accurately align the relative rotational positions of the inner container assembly and the outer container assembly during the replacement process of the inner container assembly, thus facilitating the replacement.

[0032] Referring to Figures 1 to 6, the contents container 1000 may comprise an inner container assembly 100 and an outer container assembly 200.

[0033] The inner container assembly 100 can contain contents and expel them to the outside by pressure. Furthermore, the inner container assembly 100 can move up and down along the outer container assembly 200. This movement allows for pressure to be applied to the inner container assembly 100, or to be restricted. Additionally, the inner container assembly 100 can be completely detached from the outer container assembly 200 by moving up and down. This allows for easy replacement of the inner container assembly 100 by replacing the entire inner container assembly 100 with a new one while retaining the outer container assembly 200.

[0034] Depending on the embodiment, the inner container assembly 100 can be formed from the same or similar material as a whole. For example, the inner container assembly 100 can be formed from a plastic material as a whole and may not contain any metal material. In this case, the plastic material can be a wide variety of plastic materials such as polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyketone (POK), polyetheretherketone (PEEK), polycarbonate (PC), polyoxymethylene (POM), polyethylene terephthalate (PET), and polybutylene terephthalate (PBT), and the present invention is not limited in any way to these, but covers all known plastic materials. In this case, after removing the inner container assembly 100 from the outer container assembly 200, it can be easily separated and disposed of, contributing to environmental protection and increasing the recycling rate and the reuse rate of the packaging.

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

[0036] Depending on the embodiment, if the inner container assembly 100 is protruding from the outside of the outer container assembly 200, the inner container assembly 100 can be pushed upward or the outer container assembly 200 can be pushed downward, allowing the inner container assembly 100 and the outer container assembly 200 to be separated from each other. In this case, an inner container assembly 100 that has used up its contents 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 130.

[0038] The inner container 110 can contain contents. In this case, the contents include, for example, liquid, gel, or powder cosmetics, pharmaceuticals, quasi-drugs, etc. For example, the contents include, but are not limited to, lotions, milk lotions, moisturizing lotions, nourishing lotions, skin lotions, skin softeners, skin toners, astringents, massage creams, nourishing creams, moisturizing creams, whitening essences, tone-up creams, UV protectants, sunscreen creams, sunscreen milks, BB creams, makeup bases, foundations, CC creams, concealers, blushes, contouring products, eyeshadows, eyebrow products, eye creams, primers, etc.

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

[0040] The pump assembly 120 can move its contents by pressing. For example, the pump assembly 120 can be coupled to the inner container 110 to move the contents contained in the inner container. Alternatively, for example, the pump assembly 120 can be coupled to the outer container assembly 200 and raised and lowered by the outer container assembly 200. As the pump assembly 120 is raised and lowered, the inner container 110 and the head portion 130 move up and down together, allowing the inner container assembly 100 to be raised and lowered as a whole. Various known methods of coupling, such as screwing, fitting, interlocking, and engagement, can be applied to the coupling between the pump assembly 120 and the inner container 110, and between the pump assembly 120 and the outer container assembly 200.

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

[0042] The pump unit 121 can be compressed and decompressed by pressing, thereby moving its contents. For example, the pump unit 121 may include a cylinder with an open top and bottom and a hollow interior, a seal unit that is at least partially inserted into the cylinder and seals the top of the cylinder at least partially, 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 coupled to the piston rod and moving up and down with the piston rod, and an elastic member disposed between the seal unit and the stem and providing elastic force from the seal unit toward the stem. However, the present invention is not limited in any way, and the pump unit 121 can have any known type of pump structure, such as airless type, dip tube type, spray type, etc.

[0043] Depending on the embodiment, the elastic member constituting the pump section 121 may be a bellows-type spring with repeatedly formed peaks and valleys, but with sealed sides. In this case, a stem vane can be formed on the outer side of the upper end of the stem to support the upper end of the elastic member, and a downward bent portion can be formed on the lower side of the outer end of the stem vane to support the side of the elastic member. In addition, a support groove can be formed on the top surface of the seal section into which the lower end of the elastic member is fitted, supporting the lower end and side of the elastic member, respectively. Furthermore, at least one air passage can be formed in at least one of the stem vane and the seal section to eliminate changes in internal pressure when the elastic member is compressed and decompressed.

[0044] Depending on the embodiment, the pump section 121 can be formed from the same or similar material as a whole. For example, the pump section 121 can be formed from plastic material as a whole and may not contain any metal material. In particular, the elastic members included in the pump section 121 can also be formed from plastic material instead of 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 section 121, thus increasing the recycling rate and the package reuse rate.

[0045] The undercap 122 can connect the pump unit 121 to the outer container assembly 200. For example, the undercap 122 can be connected to the inner container 110 and / or the pump unit 121 on the inside, and to the outer container assembly 200 (in particular, the connecting part 220) on the outside.

[0046] Depending on the embodiment, the undercap 122 restricts the downward movement of the pump assembly 120 from at least a portion of the outer container assembly 200 (particularly the connecting portion 220) while the pump assembly 120 and the outer container assembly 200 are connected, but allows upward movement. This allows the inner container assembly 100 to be raised by the outer container assembly 200 (particularly the connecting portion 220) when the outer container assembly 200 (particularly the rotating portion 230) is rotated, and thereafter, the inner container assembly 100 and the outer container assembly 200 can be separated by pressing the inner container assembly 100 upward or 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 contact, for example, one side of the outer container assembly 200 (particularly the upper inner end of the connecting portion 220). As a result, when at least a part of the outer container assembly 200 (particularly the connecting portion 220) rises (due to the rotation of the rotating portion 230), one side of the outer container assembly 200 (particularly the upper end of the first region 221 of the connecting portion 220) presses against the undercut 122-1, causing the undercap 122 to rise along with it. This rise of the undercap 122 allows the inner container assembly 100 as a whole to rise. Furthermore, when the inner container assembly 100 is pressed upward or the outer container assembly 200 is pressed downward while the undercap 122 is raised, the upward movement of the undercut 122-1 is not restricted, allowing the outer container assembly 200 to rise and be detached from the inner container assembly 100.

[0048] Depending on the embodiment, the undercut 122-1 can be fitted onto one side of the outer container assembly 200 (particularly the connecting portion 220), thereby connecting the undercap 122 to the outer container assembly 200 (particularly the connecting portion 220). However, the present invention is not limited to such a connection method. For example, at least one fitting groove (not shown) can be formed on the outer circumferential surface of the undercap 122, particularly on the underside of the undercut 122-1, and the undercap 122 can be fitted to the outer container assembly 200 (particularly the connecting portion 220) through this groove. In addition to these, a wide variety of known connection methods such as screwing, interlocking, and engagement can be applied, and multiple connection methods can be applied simultaneously.

[0049] Depending on the embodiment, at least one gripping portion can be formed on the outside of the undercap 122. The user can grasp the gripping portion when removing the inner container assembly 100. For example, the undercut 122-1 can serve as a gripping portion. That is, the user can remove the inner container assembly 100 from the outer container assembly 200 by grasping the undercut 122-1 and pressing the inner container assembly 100 upward or the outer container assembly 200 downward. Depending on the embodiment, a fitting groove formed on the outside of the undercap 122 may also serve as a gripping portion, or at least one gripping projection may be provided on the outside of the undercap 122 as a gripping portion. In addition to these, a wide variety of other components that can be grasped by the user can be applied as additional / alternative components.

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

[0051] Depending on the embodiment, a blade portion 133 can be formed on the head portion 130. The blade portion 133 contacts at least a part of the outer container assembly 200 (in particular, the first limiting projection 232) and restricts the downward movement of the head portion 130, thereby limiting the pressure on the head portion 130. For example, the blade portion 133 can be projected outward from the upper end of the head portion 130, but the present invention is not limited thereto, and the blade portion 133 can be formed at a wide variety of positions on the head portion 130.

[0052] Depending on the embodiment, the blade portion 133 can be formed continuously around the head portion 130. In this case, the entire area around the head portion 130 will be in contact with one side of the outer container assembly 200 (in particular, the first limiting projection 232), and the head portion 130 cannot descend no matter which part is pressed. In other words, the problem of the head portion 130 partially descending when a specific part of the head portion 130 is pressed under pressure-restricting conditions can be resolved.

[0053] Depending on the embodiment, the blade portion 133 can be formed to be inclined downward and inward. This inclined structure minimizes friction between the blade portion 133 and the outer container assembly 200 (especially the rotating portion 230) during the raising and lowering process of the head portion 130. The reduction in frictional force allows the raising and lowering of the inner container assembly 100 to become more natural, improving the user experience.

[0054] Depending on the embodiment, the nozzle portion 132 can be formed to be inclined inward and downward at an angle corresponding to that of the blade portion 133. In this case, when the inner container assembly 100 is fully inserted into the outer container assembly 200 and the blade portion 133 contacts one side of the outer container assembly 200 (particularly the first limiting projection 232), the nozzle portion 132 can also contact one side of the outer container assembly 200 (particularly the first limiting projection 232) together with the blade portion 133, eliminating the need for a fitting portion in the outer container assembly 200 for the nozzle portion 132 to be fitted into. With this structure, when the inner container assembly 100 and the outer container assembly 200 are tightened together, the blade portion 133 and the nozzle portion 132 always contact one side of the outer container assembly 200 (particularly the first limiting projection 232) simultaneously, so that the position of the nozzle portion 132 does not affect the insertion depth of the inner container assembly 100. In other words, 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 projection 134 can be provided protruding from the inside of the head portion 130. The second limiting projection 134 can guide the vertical movement path of the head portion 130 or limit the pressure applied to the head portion 130.

[0056] In one embodiment, the second limiting projection 134 can guide the vertical movement path of the head portion 130. In this case, the pump assembly 120, particularly the undercap 122, can have a first movable groove 122-2 that forms the vertical movement path of the second limiting projection 134 (see Figure 6(a)). The first movable 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 portion 130 is pressed, the second limiting projection 134 moves along the first movable groove 122-2, thereby guiding the vertical movement path of the head portion 130.

[0057] In other embodiments, the second limiting projection 134 can limit the pressure applied to the head portion 130. More specifically, the presence or absence of pressure limitation on the head portion 130 can be adjusted by rotating the head portion 130 to change the position of the second limiting projection 134. In this case, the pump assembly 120', in particular the undercap 122', can be provided with a first movable groove 122-2 that forms the vertical path of the second limiting projection 134 and a second movable groove 122-3 that forms the rotational path of the second limiting projection 134 (see Figure 6(b)). In this case, the first movable groove 122-2 may be perpendicular to the cross-section of the pump assembly 120, and the second movable 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 projection 134 is located above the first movable groove 122-2, the head portion 130 can be pressed, and when it is located above the second movable groove 122-3, the head portion 130 can be pressed. According to this, the head portion 130 can be pressed in a first range of rotation relative to the pump assembly 120', and the press can be pressed in a second range of rotation. More specifically, when the head portion 130 is in the first range of rotation, the head portion 130 can be pressed because the second limiting projection 134 is able to move up and down along the first movable groove 122-2, allowing the head portion 130 to move downward. Also, when the head portion 130 is in the second range of rotation, the head portion 130 can be pressed because the lower end of the second limiting projection 134 contacts the lower end of the second movable groove 122-3, restricting the downward movement of the head portion 130. In other words, by ensuring that the head portion 130 is within the second rotation range, it is possible to prevent the contents from being dispensed due to unintended pressing of the head portion 130.

[0058] Depending on the embodiment, the pressure applied to the head portion 130 may be limited until the inner container assembly 100 is first used. For this purpose, a stopper 140 can 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, to prevent unintended pressure on the head portion 130. The stopper 140 can be installed, for example, when the inner container assembly 100 is first placed and removed immediately before the inner container assembly 100 is coupled to the outer container assembly 200.

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

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

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

[0062] The outer container 210 can be positioned to enclose at least a portion of the inner container assembly 100, particularly at least a portion of the inner container 110. This protects the inner container 110 from external impacts and improves the thermal insulation of the inner container 110.

[0063] The connecting part 220 can connect the outer container 210 and the inner container assembly 100. For example, the connecting part 220 can connect the outer container 210 and the inner container assembly 100 by connecting the undercap 122 of the pump assembly 120 on the inside and the outer container 210 on the outside. In addition, the connecting part 220 can move up and down along the outer container 210 (when the rotating part 230 rotates). The pump assembly 120 connected to the connecting part 220 can move up and down due to the movement of the connecting part 220. In other words, the inner container assembly 100 can move up and down by the movement of the connecting part 220.

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

[0065] Depending on the embodiment, at least one locking projection 222-1 can be formed inside the connecting portion 220, particularly inside the second region 222. In this case, the lower end of the undercut 122-1 can contact the upper end of the first region, and the upper end can contact the locking projection 222-1, thereby connecting the connecting portion 220 and the inner container assembly 100. At this time, the locking projection 222-1 can be elastically deformed outward by the action of an external force. For example, if an external force is applied to the locking projection 222-1 while the undercut 122-1 is pressed upward, the locking projection 222-1 will elastically deform outward, thereby allowing the undercut 122-1 to rise. That is, the downward movement of the undercut 122-1 is limited by the first region, but the upward movement of the undercut 122-1 can be partially permitted by the elastic deformation of the locking projection 222-1. With this structure, when the rotating part 230 is rotated, the undercut 122-1 rises due to the connecting part 220, allowing the inner container assembly 100 to rise from the outer container assembly 200. After this, if the inner container assembly 100 is pressed upward or the outer container assembly 200 is pressed downward, the locking projection 222-1 elastically deforms, the undercut 122-1 rises, and the inner container assembly 100 and the outer container assembly 200 can be separated.

[0066] Depending on the embodiment, at least one fitting projection (not shown) can be formed on the connecting portion 220 to fit into the fitting groove of the undercap 122 for connecting the connecting portion 220 and the undercap 122. However, the present invention is not limited to such a connection method, and a wide variety of connection methods such as screwing and interlocking can be applied.

[0067] The rotating part 230 can raise and lower the inner container assembly 100 while rotating through the user's rotational operation. Specifically, the rotating part 230 can raise and lower the connecting part 220 through the rotational operation, thereby allowing the inner container assembly 100 connected to the connecting part 220 to be raised and lowered. For example, by being coupled to the outside of the outer container 210 and / or the connecting part 220, the rotating part 230 can receive the user's rotational operation and raise and lower the connecting part 220.

[0068] Depending on the embodiment, the outer container 210 is provided with at least one first guide groove 211, the rotating part 230 is provided with at least one second guide groove 231, and the connecting part 220 can be provided with at least one guide projection 221-1 that fits into the first guide groove 211 and the second guide groove 231. When the rotating part 230 rotates, the guide projection 221-1 moves along the first guide groove 211 and the second guide groove 231, thereby allowing the connecting part 220 to 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 projection 221-1 in the rotational direction, causing the guide projection 221-1 to rotate, thereby allowing the guide projection 221-1 to move along the first guide groove 211. As the guide projection 221-1 moves along the first guide groove 211, the connecting portion 220 can move up and down along the outer container 210.

[0069] Depending on the embodiment, the first guide groove 211 may be formed spirally with respect to the cross-section of the outer container 210, and the second guide groove 231 may be formed perpendicular to the cross-section of the rotating part 230. In this case, when the rotating part 230 rotates, the guide projection 221-1 moves spirally along the first guide groove 211, allowing the connecting part 220 and the inner container assembly 100 to rotate and move up and down. However, the present invention is not limited thereto, and a wide variety of embodiments are applicable, such as when the first guide groove 211 is formed vertically and the second guide groove 231 is formed spirally.

[0070] Depending on the embodiment, a first limiting projection 232 can be provided to project inward along the inner circumferential surface of the upper end of the rotating part 230. The first limiting projection 232 can contact at least a part of the inner container assembly 100, in particular the lower end of the wing portion 133 of the head portion 130. This prevents the inner container assembly 100 from being pressed when the top surface of the inner container assembly 100 is at a height corresponding to the top surface of the outer container assembly 200.

[0071] Depending on the embodiment, the first limiting projection 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 blade part 133 as a whole. As a result, when the top surface of the inner container assembly 100 is at a height corresponding to the top surface of the outer container assembly 200 and the first limiting projection 232 and the blade part 133 are in contact with each other, the pressure on the head part 130 can be limited by the first limiting projection 232 and the blade part 133 regardless of which area of ​​the head part 130 is pressed.

[0072] Depending on the embodiment, the first limiting projection 232 does not have to protrude vertically from the inner circumferential surface of the rotating portion 230 and form an inclination, or it may be formed to inclin downward and inward in correspondence with the blade portion 133 and / or nozzle portion 132. Regardless of the shape, the first limiting projection 232 can contact one side of the blade portion 133 and / or nozzle portion 132 to prevent the head portion 130 from being pressed.

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

[0074] Depending on the embodiment, a fitting portion may not be formed in one area of ​​the first limiting projection 232. In this case, for example, the first limiting projection 232 is formed as the entire inner circumferential surface of the upper end of the rotating portion 230, allowing for continuous connection. The first limiting projection 232 is in contact with the blade portion 133 and the nozzle portion 132 as a whole, preventing both the blade portion 133 and the nozzle portion 132 from descending. Such prevention of descending is achieved independently of the relative rotational position between the head portion 130 and the rotating portion 230, thereby achieving a non-directional fastening structure between the head portion 130 and the rotating portion 230, i.e., a non-directional fastening structure between the inner container assembly 100 and the outer container assembly 200. This non-directional fastening structure simplifies the production and assembly processes of the product, and eliminates the need to precisely align the relative rotational positions of the inner container assembly 100 and the outer container assembly 200 during the replacement process of the inner container assembly 100, making replacement more convenient.

[0075] The contents container 1000 shown in Figures 1 to 6 are merely illustrative examples, and a wide variety of configurations can be applied depending on the embodiment to which the present invention is applied.

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

[0077] Referring to Figure 7, when the inner container assembly 100 is inserted into the outer container assembly 200, the wing portion 133 protruding outward from the upper end of the head portion 130 comes into contact with the first limiting projection 232 protruding from the inner circumferential surface of the rotating portion 230. At this time, the wing portion 133 is formed to be inclined downward and inward, and at the same time, the nozzle portion 132 can also be formed to be inclined downward and inward at an angle corresponding to that of the wing portion 133. In this case, when the wing portion 133 is in contact with the first limiting projection 232, the nozzle portion 132 can also come into contact with the first limiting projection 232 in the same way, and thus the first limiting projection 232 does not need to have a fitting portion for the nozzle portion 132 to be fitted into.

[0078] As a result, when the inner container assembly 100 is removed from the outer container assembly 200 and inserted into the outer container assembly 200, the wing portion 133 and the nozzle portion 132 always contact the first limiting projection 232 simultaneously. Therefore, 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 projection 232 prevents it from descending. In other words, a non-directional fastening structure can be applied to the inner container assembly 100 and the outer container assembly 200. With such a non-directional fastening structure, it becomes unnecessary to precisely align the relative rotational positions of the inner container assembly 100 and the outer container assembly 200 during the production and assembly processes of the product and the process of replacing the inner container assembly 100, thus increasing productivity and making replacement more convenient.

[0079] The non-directional fastening structure shown in Figure 7 is merely illustrative, and a wide variety of configurations can be applied depending on the embodiment of the present invention.

[0080] Figure 8 is a diagram illustrating the protruding operation of the head portion according to an embodiment of the present invention. To show the internal structure, the rotating portion 230 is indicated by a dashed line.

[0081] Referring to Figure 8, as the rotating part 230 rotates, the second guide groove 231, which is formed perpendicular to the cross-section of the rotating part 230, can rotate and press the guide projection 221-1 in the rotational direction. As a result, the guide projection 221-1 can move along the first guide groove 211, which is formed spirally with respect to the cross-section of the outer container 210. As the guide projection 221-1 moves along the first guide groove 211, the connecting part 220 can rotate and move up and down along the outer container 210. As the connecting part 220 moves up and down, the inner container assembly 100 connected to the connecting part 220 can also move up and down, thereby allowing the head part 130 to protrude from the outer container assembly 200 or be inserted into the inside of the outer container assembly 200.

[0082] The head's protruding motion shown in Figure 8 is merely illustrative, and a wide variety of methods can be applied depending on the embodiment to which the present invention is applied.

[0083] Figure 9 is a diagram illustrating the overall usage method of the contents container according to an embodiment of the present invention.

[0084] Referring to Figure 9, when the rotating part 230 is rotated in one direction, the connecting part 220 rises due to the rotating part 230, which in turn raises the pump assembly 120 connected to the connecting part 220, allowing the inner container assembly 100 to rise. In this case, the inner container assembly 100 can protrude to the outside of the outer container assembly 200, and the pressing restriction on the head part 130 by the first limiting projection 232 can be released. The user can compress the pump assembly 120 by pressing the head part 130, thereby discharging the contents to the outside of the nozzle part 132.

[0085] After this, with the inner container assembly 100 protruding from the outside of the outer container assembly 200, the inner container assembly 100 can be pushed upward or the outer container assembly 200 can be pushed downward to separate them. At this time, the user can separate the inner container assembly 100 and the outer container assembly 200 even more easily by grasping the undercut 122-1 of the inner container assembly 100. Through this, while holding the outer container assembly 200, only the inner container assembly 100 that has 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 method shown in Figure 9 is merely illustrative, and a wide variety of methods can be applied depending on the embodiment to which the present invention is applied.
