Referring to fig. 1 to 5, the content container 1000 may include an inner container 100 and an outer container assembly 200.

The inner container 100 may house contents. In this case, the content may be a liquid, gel or powder cosmetic. For example, the contents may include lotions, emulsions, moisturizing lotions, nutritional emulsions, astringent lotions, skin soothing lotions, astringent, massage cream, nutritional cream, moisturizing cream, whitening essence, skin cream, sunscreens, sunblocks, sun blocks, BB cream, foundation, CC cream, concealer, blush, shadows, eye shadows, eyebrow powder, eye cream, pre-makeup cream, and the like. However, the present invention is not limited thereto, and may include cosmetics, medicines, external medicines, and the like of other textures or types.

In an embodiment, the inner container 100 may include a receptacle 110 and a neck 120.

The housing 110 may be formed with a housing space for housing the contents therein. For example, the housing 110 may be a container having an upper portion opened and a lower portion closed to form a housing space therein, but this is only an example, and various embodiments such as opening the upper and lower portions of the housing 110 or opening the side surfaces of the housing 110 may be applied. For example, the housing 110 may be freely selected from containers having a housing space formed inside in various known forms such as bottles (bottles), cans (Jar), tubes (Tube), bags (Pouch).

The neck 120 is disposed above the housing 110, the inside and the outside of the housing 110 communicate with each other through the neck 120, and a region for coupling with the outer container assembly 200 may be formed in the neck 120.

In an embodiment, an edge portion 121 may be formed to protrude along an outer circumferential surface of the neck portion 120. The rim 121 is formed to be spaced apart from the upper end of the receiving portion 110 so that at least a portion of the outer container assembly 200 (particularly, the coupling protrusion 233) is inserted into a separation space formed between the upper end of the receiving portion 110 and the rim 121, whereby the inner container 100 and the outer container assembly 200 can be coupled.

In an embodiment, the inner container 100 may further comprise a disc 130. The disk 130 is disposed inside the housing 110, and can push up the contents as the contents housed in the housing 110 are exhausted. For example, when the volume of the content in the storage portion 110 is reduced by discharging the content while the disk 130 is kept in close contact with the inner wall of the storage portion 110, the disk 130 rises in accordance with the reduced volume, and the content is lifted upward.

The outer container assembly 200 can house the inner container 100. For example, the outer container assembly 200 may surround at least a portion of the inner container 100 and be bonded to the outside of the inner container 100. Further, for example, the outer container assembly 200 may be formed to be opened at a lower portion and/or an upper portion, so that the inner container 100 is inserted into the outer container assembly 200 or separated from the outer container assembly 200.

In an embodiment, the outer container assembly 200 may be coupled with the inner container 100 to relatively rotate the inner container 100. When at least a portion of the outer container assembly 200 (particularly the rotating portion 220) is rotated in a direction with respect to the inner container 100, at least a portion of the inner container 100 is exposed to the lower side of the outer container assembly 200. The exposed inner container 100 can be more easily separated from the outer container assembly 200. Further, when the content contained in the inner container 100 is exhausted, the inner container 100 can be easily separated from the outer container assembly 200 by only a simple operation of rotating at least a part of the outer container assembly 200 (particularly, the rotating portion 220), and then the inner container containing a new content can be coupled to the outer container assembly 200.

In an embodiment, the outer assembly 200 may include an outer container 210, a rotating portion 220, a lifting portion 230, a guiding portion 240, a pump assembly 250, and/or a head 260.

The outer container 210 may be formed with an accommodating space in which the inner container 100 is accommodated. For example, the outer container 210 may be a container of an upper and lower open shape to form a receiving space inside, but this is merely an example, and various embodiments such as an upper opening, a lower closing, or a side opening of the outer container 210, etc. of the outer container 210 may also be applied. For example, the outer container 210 may be freely selected from various containers having a housing space formed inside and having a known shape, such as bottles (bottles), cans (Jar), tubes (Tube), and bags (Pouch).

In an embodiment, an opening portion 211 may be formed at a lower end of the outer container 210. The inner container 100 may be inserted into the inner side of the outer container 210 through the opening 211. For example, in a state where the structures of the outer container 210, the rotating portion 220, and the lifting portion 230 are coupled, when the inner container 100 is inserted through the opening portion 211, at least a part of the outer container assembly 200 (particularly, the coupling protrusion 233) may be inserted into a separation space formed between the upper end of the receiving portion 110 and the edge portion 121, thereby coupling the inner container 100 and the lifting portion 230.

In an embodiment, at least one first insertion protrusion 212 may be formed at the inner side of the outer container 210. The first insertion protrusion 212 is inserted into at least a portion of the pump assembly 250 (particularly, the first insertion groove 252-1) so that the outer container 210 and the pump assembly 250 can be integrally rotated with respect to the rotating part 220. For example, the first insertion protrusion 212 may be formed to protrude inward at a prescribed length on the upper inner circumferential surface of the outer container 210.

The rotating part 220 may raise and lower the elevating part 230 by receiving a user's rotation operation. Further, at least a portion of the inner container 100 may be exposed to the lower side of the outer container assembly 200 when the rotating part 220 is rotated in one direction. For this purpose, for example, the rotating part 220 may be disposed at an upper side of the outer container 210 so as to be relatively rotatable with respect to the outer container 210.

In an embodiment, at least one hooking protrusion 221 may be formed at one side of the rotating part 220. By inserting the hooking protrusion 221 into at least a part of the elevating portion 230 (particularly, the hooking groove 231), the rotating portion 220 and the elevating portion 230 can be coupled to be rotatable in synchronization. For example, the hooking protrusion 221 may be formed to protrude at a predetermined length in the longitudinal direction at the lower end of the rotating part 220.

The elevating part 230 may move in the up-down direction according to the rotation of the rotating part 220. For example, when the rotating portion 220 is rotated in one direction, the lifting portion 230 is rotated and lowered, and the lower end portion of the lifting portion 230 can press the inner container 100 downward. Thereby, the inner container 100 may be exposed to the lower side of the outer container 210 through the opening 211. For this purpose, the lifting part 230 is coupled to the rotating part 220 so as to be rotatable in synchronization, and may be disposed at an upper side of the inner container 100.

In an embodiment, at least one hooking groove 231 into which the hooking protrusion 221 is inserted may be formed at the inner side of the elevation part 230. The rotation part 220 and the elevation part 230 can be coupled in a synchronous rotation by coupling the hooking protrusion 221 and the hooking groove 231. For example, the hooking groove 231 may be formed by recessing or penetrating at least a region of the inner circumferential surface of the elevating portion 230 to the outer circumferential surface. However, the above coupling structure is only an example, and various well-known coupling structures capable of coupling the rotating part 220 and the elevating part 230 in a synchronized rotation manner may be included in addition to the hooking protrusion 221 and the hooking groove 231.

In an embodiment, the inner side of the elevation 230 may be formed with at least one guide protrusion 232. The guide protrusion 232 may guide the lifting of the lifting part 230 when a rotation operation is applied to the rotation part 220. For example, the guide protrusion 232 may be formed to protrude from an inner side surface of the elevating portion 230 and be inserted into at least a portion of the guide portion 240 (particularly, the guide groove 241). Thereby, when the rotating part 220 is rotated, the guide protrusion 232 moves along at least a portion of the guide part 240 (particularly, the guide groove 241), so that the lifting part 230 can be lifted.

In an embodiment, at least one coupling protrusion 233 may be formed at an inner side of the elevation part 230. The coupling protrusion 233 is inserted into a separation space formed between the upper end of the receiving portion 110 and the edge portion 121, and can couple the inner container 100 and the lifting portion 230. At this time, at least one region of the elevation part 230 may be bent outward when the inner container 100 is inserted inside the outer container 210. Then, when the coupling protrusion 233 is inserted into the partitioned space to complete the coupling of the inner container 100 and the outer container assembly 200, at least a part of the shape of the elevation part 230 may be restored. For this reason, at least one region of the elevating portion 230 may be formed of a soft material, and the coupling protrusion 233 is formed to protrude inward by a predetermined length on the inner circumferential surface of the one region, but the material of the elevating portion 230 is not limited thereto.

At least a portion of the guide portion 240 may be coupled to the inside of the elevation portion 230 to guide the moving direction of the elevation portion 230. For this, for example, a guide groove 241 into which the guide protrusion 232 is inserted may be formed at the outer side of the guide portion 240. For example, the guide groove 241 is formed to have an inclination in at least one region, and may be formed by recessing or penetrating the outer peripheral surface of the guide portion 240 to the inner peripheral surface. Thereby, the lifting portion 230 can be lifted and lowered by applying a rotation operation to the rotation portion 220 to rotate the lifting portion 230 together with the rotation portion 220 and simultaneously moving the guide protrusion 232 along the guide groove 241.

In an embodiment, a limiting stage 241-1 may be formed at one side of the guide groove 241. The limiting table 241-1 may adjust the radius of rotation of the rotating portion 220. Specifically, when the rotation part 220 is rotated in one direction and the guide protrusion 232 is in contact with the end of the restriction table 241-1 while moving along the guide groove 241, further rotation of the lifting part 230 and the rotation part 220 is restricted, preventing the lifting part 230 from being separated from the guide part 240. For example, the guide groove 241 extends downward from the lower end, and the restricting stage 241-1 is formed to protrude outward on one side of the extending guide groove 241.

In an embodiment, at least one second insertion protrusion 242 may be formed at an outer side of the guide part 240. The second insertion protrusion 242 is inserted into at least a portion of the pump assembly 250 (particularly, the second insertion groove 252-2) so that the guide 240 and the pump assembly 250 can be integrally rotated with respect to the rotating part 220. For example, the second insertion protrusion 242 may be formed to protrude outward by a predetermined length on the upper outer circumferential surface of the guide portion 240.

The pump assembly 250 is disposed above the inner container 100, and can move the contents contained in the inner container 100 by pressurization. Specifically, the pump assembly 250 may be disposed between the inner container 100 and the head 260, and when the head 260 is pressurized, the pump assembly 250 compresses or decompresses and moves the contents to the head 260 side.

In an embodiment, the pump assembly 250 may include a pump portion 251 and a pump support 252.

The pump part 251 may compress or decompress by pressurizing and move the contents. For example, the pump part 251 may include: a cylinder having an upper portion and a lower portion opened and a hollow interior; the sealing cover is tightly attached to the cylinder in the cylinder and is lifted; the piston rod is wrapped by the sealing cover and is lifted relative to the cylinder; and a rod coupled to the piston rod and elevated together with the piston rod. Further, for example, the pump part 251 may include a suction pipe extending from a lower end of the cylinder to an inner side of the receiving part 110. The structure of the pump part 251 is merely an example, and the pump part 251 may include all known pump structures.

The pump support 252 may fix the pump part 251 to the outer container 210. For example, at least one through hole is formed inside the pump support body 252, and the pump portion 251 is inserted inside the through hole, thereby being coupled to the pump support body 252. This is merely an example, and various embodiments, such as integrally forming the pump part 251 and the pump support 252, may be applied.

Further, for example, the pump support 252 may be coupled between the outer container 210 and the guide 240, fixing the pump 251 to the outer container 210. In this case, the pump support 252 may be coupled to the upper side of the outer container 210 and/or the upper side of the guide 240 by insert coupling, but is not limited thereto, and various coupling such as screw coupling, hooking coupling, fitting coupling, and hooking coupling may be applied.

In an embodiment, at least one first insertion groove 252-1 into which the first insertion protrusion 212 is inserted may be formed at the outer side of the pump support body 252. By the combination of the first insertion projection 212 and the second insertion groove 252-1, the outer container 210 and the pump assembly 250 can be rotated integrally with respect to the rotating portion 220 when the outer container 210 is rotated (for example, when the outer container 210 and the rotating portion 220 are rotated relatively). For example, the first insertion groove 252-1 may be formed by recessing or penetrating the outer circumferential surface of the pump support body 252 to the inner circumferential surface. However, the above coupling structure is merely an example, and includes various well-known coupling structures capable of coupling the outer container 210 and the pump assembly 250 in a synchronous rotation manner, in addition to the first insertion protrusion 212 and the first insertion groove 252-1.

In an embodiment, at least one second insertion groove 252-2 into which the second insertion protrusion 242 is inserted may be formed at the inner side of the pump support body 252. By the combination of the second insertion protrusion 242 and the second insertion groove 252-2, the pump assembly 250 and the guide 240 can be rotated integrally with respect to the rotating part 220 when the outer container 210 is rotated (for example, when the outer container 210 is rotated relative to the rotating part 220). For example, the second insertion groove 252-2 may be formed by recessing or penetrating the inner circumferential surface of the pump support body 252 to the outer circumferential surface. However, the above coupling structure is merely an example, and includes various well-known coupling structures capable of coupling the guide 240 and the pump assembly 250 in a synchronous rotation manner, in addition to the second insertion protrusion 242 and the second insertion groove 252-2.

For example, when the outer container 210, the pump assembly 250, and the guide 240 are sequentially combined, the outer container 210, the pump assembly 250, and the guide 240 may integrally rotate independently of the rotation of the rotating part 220. Thus, when a rotation operation is applied to the rotation part 220, only the lifting part 230 can be rotated up or rotated down along with the guide part 240 independent of the rotation part 220.

The head 260 is disposed above the pump assembly 250, and receives a user's pressurizing operation, so that the contents moved by the pump 251 can be discharged to the outside. The head 260 may be provided with a passage 261 communicating with the pump assembly 250 and a discharge port 262 for discharging the content. When the user pressurizes the head 260, the head 260 transmits the pressurization to the pump assembly 250, and then the contents moved from the pump assembly 250 by the passage 261 may be discharged to the outside through the discharge port 262.

The content container 1000 of fig. 1 to 5 is an example, and various structures may be applied according to an embodiment to which the present invention is applicable.

Fig. 6 is a drawing for explaining the operation of the content container according to the embodiment of the present invention. Specifically, a of fig. 6 is a perspective view of the content container before rotating the rotating portion in one direction, and b of fig. 6 is a perspective view of the content container after rotating the rotating portion in one direction. The outer container 210 is omitted in fig. 6 for the purpose of illustrating the internal structure, but the outer container 210 is obviously also included.

Referring to fig. 6, as the rotating part 220 is rotated in a direction with respect to the outer container 210, the lifting part 230 (through the coupling of the hooking protrusion 221 and the hooking groove 231) may be rotated together with the rotating part 220. At this time, the elevating part 230 may be rotatably lowered while the guide protrusion 232 moves along the guide groove 241 of the guide part 240. The lower end of the lifting unit 230 may be pressed downward against the inner container 100 disposed below the lifting unit 230 while the lifting unit 230 is lowered. Thereby, the inner container 100 can be exposed to the outside of the outer container 211 (through the opening portion 211).

Further, when the guide protrusion 232 moving along the guide groove 241 contacts the end of the restriction stage 241-1, further rotation of the elevating part 230 and the rotating part 220 may be restricted, preventing the elevating part 230 from being separated from the guide part 240.

The operation of the content container 1000 of fig. 6 is an example, and various modes of operation may be applied according to embodiments to which the present invention is applicable.

Fig. 7 is a drawing for explaining the operation of the content container according to the embodiment of the present invention. Specifically, fig. 7 a is a cross-sectional view of the content container before the rotating portion is rotated in one direction, fig. 7 b is a cross-sectional view of the content container after the rotating portion is rotated in one direction, and fig. 7 c is a cross-sectional view of the content container in a state in which the inner container is separated from the outer container assembly.

Referring to fig. 7, by rotating the rotating part 220 in a direction with respect to the outer container 210, the lifting part 230 may be rotated together with the rotating part 220. At this time, since the outer container 210, the pump assembly 250 and the guide 240 are sequentially coupled, the outer container 210, the pump assembly 250 and the guide 240 may integrally rotate independently of the rotation of the rotating part 220.

The elevating part 230 is rotated and lowered while moving along with the guide part 240. The lower end of the lifting unit 230 may be pressed downward against the inner container 100 disposed below the lifting unit 230 while the lifting unit 230 is lowered. Since the inner container 100 is exposed to the lower side of the outer container 210 (through the opening portion 211), the exposed inner container 100 can be pulled to be easily separated from the outer container assembly 200. At this time, the guide protrusion 232 is hung on the restricting stage 241-1, so that the lifting part 230 can be separated only from the inner container 100 without being separated from the guide part 240. Thus, when the content contained in the inner container 100 is exhausted, the inner container 100 can be easily separated from the outer container assembly 200 only by a simple operation of rotating the rotating portion 220, and then the inner container containing a new content can be coupled to the outer container assembly 200 (via the opening portion 211).

The content container 1000 of fig. 7 is an example, and various modes of operation may be applied according to an embodiment to which the present invention is applicable.

Referring to fig. 8, a container kit 3000 may include a content container 1000 and at least one refill container 2000. In this case, the same description as the content container 1000 shown in fig. 1 to 5 may be given to the content container 1000.

In an embodiment, the inner container 1000 may further comprise a lid 300. The lid 300 can prevent foreign substances, moisture, or the like from entering the interior of the content container 1000 by opening or closing the upper end of the outer container assembly 200 (particularly, the discharge port 262 of the head 260). For example, the cover 300 may be coupled to the upper side of the outer container assembly 200 (particularly, the rotating part 220) so as to be detachable, but the coupling manner is not limited thereto, and various coupling such as screw coupling, insert coupling, fitting coupling, and hitching coupling may be applied.

The refill container 2000 may include an inner container 100' and a refill cap 400. At this time, the description of the inner container 100' of the refill container 2000 is the same as the inner container 100 of the content container 1000.

The refill cap 400 may surround at least a portion of the inner container 100' (particularly the neck 110 ') and be removably coupled to the inner container 100'. The refill cover 400 may prevent contamination of the contents with foreign substances by sealing the upper end of the inner container 100'. When the content of the content container 1000 is exhausted, the user can separate the inner container 100 from the outer container assembly 200 and the lid 300, and insert the inner container 100' from which the refill lid 400 is separated into the inner side of the outer container assembly 200 of the content container 1000 from the refill container 2000. At this time, only the inner container 100 can be separated from the outer container assembly 200 to be easily discharged, and since the outer container assembly 200, particularly the pump assembly 250, can be reused, waste can be reduced to a very small amount.

The container set 3000 of fig. 8 is an example, and various compositions may be applied according to an embodiment to which the present invention is applicable.

As described above, the preferred embodiments are disclosed in the accompanying drawings and description. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the claims. Accordingly, it is to be understood that various modifications and equivalent other embodiments may be made by those skilled in the art. Therefore, the true technical protection scope of the present invention shall be subject to the technical ideas of the appended claims.
