In order to achieve the above objective, the container according to the present invention comprises: a container body that has bottom and sidewall parts forming a content storage part, and has a content discharge part connected to the upper end of the sidewall part; and an opening means for opening the bottom surface or lower end part of the container body.

Description

A container that allows easy discharge of remaining contents

[0001] The present invention relates to a container that allows easy discharge of remaining contents, and more specifically, to a container that allows various contents (cosmetics, shampoo, rinse, kitchen detergent, etc.) of liquid, liquid, gel, cream type, etc. to be stored therein and used by completely discharging the contents without leaving any remaining contents inside the container.

[0002] Containers for storing various contents, especially containers for storing contents of liquid, liquid, gel, and cream type, are widely used in various products such as cosmetics, shampoo, rinse, and kitchen detergent.

[0003] In particular, the pumping container is structured such that a pumping part elastically supported by a spring is connected to the head of the container to which the injection pipe is connected, and an opening / closing ball is provided in the inlet port inside the plug, so that when the pumping part is pressed, the spring is compressed and the contents inside the head are discharged, and when the external force on the pumping part is released, the pumping part is raised and returned by the spring, and the pressure inside the head is lowered, so that the ball that was closing the inlet port is lifted and opened, and the contents are refilled in the head.

[0004] A container combined with such a pumping device has the disadvantage of being inconvenient to use because it is difficult to directly pump the contents into the injection tube when the contents are almost used up and only a small amount remains at the bottom of the container.

[0005] There is a method of tilting the container to gather the contents in one place and pumping it by aligning the injection tube to that point, but it is very inconvenient to use.

[0006] Alternatively, you can completely detach the pumping device from the container and tilt the container to empty it directly, but this is also cumbersome as excessive contents may spill out.

[0007] Another method is to fill the container with an appropriate amount of water when only a small amount of contents remain and then use the pumping device to continue using the product. However, in many products, the pumping device itself is not easily separated from the container.

[0008] Therefore, even though a small amount of contents remain inside the container, there are cases where it is thrown away as it is because it is inconvenient and difficult to use. Containers with contents remaining in this way require internal cleaning when recycled, which increases disposal costs. In addition, if they are not recycled and are discarded as is, there is the problem of causing environmental pollution.

[0009] Accordingly, the present invention has been devised to solve the above-mentioned problems.

[0010] The purpose of the present invention is to provide a container that can be used by completely discharging the remaining contents inside the container, including an opening means that opens the lower part or bottom of the container body.

[0011] In order to achieve the above purpose, the container according to the present invention,

[0012] A container body having a bottom and side wall portions forming a contents storage portion, and a contents discharge portion connected to the upper end of the side wall portion;

[0013] It is characterized by including an opening means for opening the lower part or bottom surface of the above container body.

[0014] And in the container according to the present invention,

[0015] The above container body is composed of an upper body having a first side wall portion forming a lower opening, a second side wall portion forming an upper opening, and a lower body having a bottom portion connected to a lower end of the second side wall portion, and an upper end of the second side wall portion connected to a lower end of the first side wall portion.

[0016] The above opening means is characterized in that it comprises a detachable means that allows the lower portion of the first side wall portion and the upper portion of the second side wall portion to be detached.

[0017] Also, in the container according to the present invention,

[0018] The above container body includes a discharge hole formed in the bottom portion,

[0019] The above opening means is characterized in that it is composed of a residual discharge means that opens and closes the discharge hole.

[0020] In addition, in the container according to the present invention,

[0021] The above discharge hole is formed as a lower spout portion protruding from the bottom surface of the bottom portion and having screw threads formed on the outer surface,

[0022] The above residual discharge means is characterized by being composed of a plug connected to the lower spout.

[0023] The container according to the present invention,

[0024] The main body of the container is divided into an upper body and a lower body, which can be separated from each other, so that the remaining contents inside the container can be completely discharged and used, thereby providing an eco-friendly container by completely using the contents while reducing the cleaning cost when recycling.

[0025] By introducing various detachable means such as cutting lines, tapes, and screw fastening methods, and by selecting and manufacturing the upper and lower body joint structure appropriately according to the type of contents to be stored, versatility can be increased.

[0026] A separate discharge hole is added to the bottom of the container body, and a residual amount discharge means for opening and closing the discharge hole is provided, so that the remaining contents in the container can be completely discharged without shaking or shaking the container.

[0027] In particular, by introducing a plug-type residual discharge means or a cock-type residual discharge means, a residual discharge means is provided according to the type of contents, so that various types of contents can be completely discharged.

[0028] By adding a removable lower cap to the bottom of the container body, the container can be safely stood upright and stored, while also preventing the discharge hole from being opened unintentionally, making it safer to use.

[0058] Hereinafter, a container according to the present invention will be described with reference to the attached drawings.

[0059] The present invention relates to a container capable of storing and preserving various contents such as liquid, liquid, gel, cream type, etc., such as cosmetics, shampoo, rinse, kitchen detergent, etc., as shown in FIGS. 1 to 9.

[0060] The present invention comprises a container body having a bottom and a side wall forming a contents storage portion, and a contents discharge portion connected to the upper end of the side wall portion.

[0061] It includes an opening means for opening the lower part or bottom surface of the above container body.

[0062] Below, the first embodiment of FIGS. 1 to 4, the second embodiment of FIGS. 5 to 8, and the third embodiment of FIGS. 9 and 10 are separately described.

[0063] As a first embodiment, the present invention largely includes an upper body (10), a lower body (20), and a detachable means.

[0064] Specifically, the present invention

[0065] An upper body (10) having a first side wall portion (12) forming a lower opening (11),

[0066] A lower body (20) having a second side wall portion (22) forming an upper opening (21) and a bottom portion (23) connected to the lower end of the second side wall portion (22), and the upper end of the second side wall portion (22) is connected to the lower end of the first side wall portion (12).

[0067] It includes a detachable means that enables the lower part of the first side wall portion (12) and the upper part of the second side wall portion (22) to be detached.

[0068] The overall shape of the container composed of the upper body (10) and the lower body (20) can be various shapes such as cylindrical or square columnar, but in the case of the screw connection method of Fig. 3, it is limited to a cylindrical shape.

[0069] The upper body (10) and lower body (20) are made of various plastic materials used in general household goods, and in some cases, metal materials may be used.

[0070] And the shape or structure of the upper part of the upper body (10) can be changed in various ways (for example, a pumping container shape, or a simple lid-attached container shape, etc.).

[0071] As one of the core elements of the present invention, the detachable means is divided into a first embodiment of a cut-off type as shown in FIG. 1, a second embodiment of a male-female coupling type as shown in FIG. 2, and a third embodiment of a screw coupling type as shown in FIG. 3.

[0072] First, as an example of the present invention, the detachable means includes a cutting line (C) formed at a point where the lower end of the first side wall portion (12) and the upper end of the second side wall portion (22) meet and are connected, and a tape (T) attached while wrapping the lower outer surface of the first side wall portion (12) and the upper outer surface of the second side wall portion (22) so as to surround the cutting line (C).

[0073] That is, in the form of a general container, the upper body (10) and the lower body (20) are formed as an integral body and are separated by a cutting line (C), and a separate cutting means is added to one end of the cutting line, or the upper body (10) and the lower body (20) are separated from each other by only the cutting line (C), so that the contents inside the container can be directly discharged and used.

[0074] At this time, the above-mentioned cutting line (C) may be formed in a form that completely penetrates both sides of the connection portion between the upper body (10) and the lower body (20) to prevent leakage of the contents with the tape (T), or the cutting line (C) may be formed in a groove shape on both sides of the connection portion between the upper body (10) and the lower body (20) to thin a portion of the corresponding portion and to form a form in which the cutting line (C) portion is cut when a certain amount of force is applied and twisted.

[0075] The above tape (T) is attached to cover and reinforce the connecting portion where the above-mentioned cut line (C) is formed, and can be attached using an adhesive or by a heat shrink method.

[0076] In this embodiment, after the contents are stored and manufactured, when the user has almost used up the contents, the tape (T) is removed and the upper body (10) and the lower body (20) are separated using the cutting line (C), thereby easily discharging the contents remaining in the first side wall (12) of the upper body (10) or the second side wall (22) and bottom (23) of the lower body (20), thereby enabling the remaining contents to be completely used.

[0077] Next, as another example of the present invention,

[0078] The lower body (20) includes a step portion (24) that is bent inwardly from the upper end of the second side wall portion (22) to support the lower end of the first side wall portion (12), and an inner wall portion (25) that is bent upwardly from the inner end of the step portion (24) to fit into the lower opening (11) of the first side wall portion (12).

[0079] The above detachable means includes a tape (T) attached while wrapping around the lower outer surface of the first side wall portion (12) and the upper outer surface of the second side wall portion (22).

[0080] The first side wall portion (12) and the second side wall portion (22) are formed in a form in which their ends meet on the same vertical line, and the step portion (24) is bent in the inner horizontal direction at the upper end of the second side wall portion (22) by a width corresponding to the thickness of the first side wall portion (12), and then the inner wall portion (25) is bent in the vertical direction by a predetermined height at the inner end and connected.

[0081] When the inner wall portion (25) is fitted into the lower opening portion (11) of the upper body (10), the inner wall portion (25) is pressed against the inner surface of the first side wall portion (12), and the ends of the first side wall portion (12) and the second side wall portion (22) come into contact with each other, thereby completing the joining of the container, and the tape (T) is attached to cover the area where the first side wall portion (12) and the second side wall portion (22) come into contact.

[0082] In this embodiment, after removing the tape (T), the lower body (20) is taken out from the upper body (10), and the remaining contents remaining inside the upper body (10) and lower body (20) are easily discharged, so that they can be used completely.

[0083] Next, as another example of the present invention,

[0084] The lower body (20) includes a step portion (24) that is bent inwardly from the upper end of the second side wall portion (22) to support the lower end of the first side wall portion (12), and an inner wall portion (25) that is bent upwardly from the inner end of the step portion (24) to fit into the lower opening (11) of the first side wall portion (12).

[0085] The above detachable means includes a first screw thread (12a) formed on the lower inner surface of the first side wall portion (12) and a second screw thread (25a) formed on the outer surface of the inner wall portion (25) and coupled to the first screw thread (12a).

[0086] The third embodiment has the same structure as the second embodiment, but differs in that a first screw thread (12a) and a second screw thread (25a) that can engage with each other are formed on the inner surface of the first side wall portion (12) and the outer surface of the inner wall portion (25), respectively.

[0087] In this embodiment, the container is completed by screwing the upper body (10) and the lower body (20), and the contents inside the container can be completely used by separating the upper body (10) and the lower body (20) in the direction of loosening the screws, and the tape (T) may be additionally attached.

[0088] The above tape (T) may be a dedicated tape (T) for joining the upper body (10) and the lower body (20), or may be configured by replacing the tape (T) with a label for displaying information such as the product name.

[0089] Next, a modified example of Fig. 3 will be described with reference to Fig. 4.

[0090] The upper body (10) includes a sealing portion (14) having an annular flange portion (13) protruding from a predetermined height on the lower inner surface of the first side wall portion (12), and a fitting portion (14a) formed by bending downward from the inner end of the annular flange portion (13) and screw-connecting the inner wall portion (25) between the first side wall portion (12) and the sealing portion (14) extending lower than the lower end of the first side wall portion (12) and having a hook protrusion (14b) formed at the lower end thereof.

[0091] The lower body (20) includes a mounting groove (26) formed on the inner edge where the upper end of the second side wall portion (22) and the step portion (24) are connected, and an O-ring (27) fitted into the mounting groove (26) but mounted so that a portion thereof protrudes inward.

[0092] When the upper body (10) and lower body (20) are screw-connected, the hook projection (14b) presses the protrusion of the O-ring (27) to ensure airtightness.

[0093] The above fitting portion (14a) and the inner wall portion (25) have corresponding shapes, and when the upper body (10) and the lower body (20) are screw-connected, the upper end of the inner wall portion (25) pushes the hook projection (14b) inward to spread it apart, thereby screw-connecting.

[0094] At this time, the hook protrusion (14b) is formed so that its outer tip is aligned with the height of the bottom surface of the step portion (24) and is in contact with the inner surface of the second side wall portion (22).

[0095] When the inner wall portion (25) is fitted into the fitting portion (14a) and the screw connection is completed, the sealing portion (14) that was opened inward as the hook projection (14b) passes over the step portion (24) is restored to its original shape, and the outer tip of the hook projection (14b) presses the protrusion of the O-ring (27), thereby filling the gap between the upper body (10) and the lower body (20).

[0096] And even if a small amount of contents leaks through the O-ring (27), the gap between the inner wall portion (25) and the first side wall portion (12) forms a bypass path in the shape of a ‘ㄷ’, so that a small amount of contents does not leak out of the container.

[0097] Next, a second embodiment of the present invention will be described.

[0098] The present invention

[0099] A container body (100) having a bottom portion (120) and a side wall portion (130) forming a contents storage portion (110), a contents discharge portion connected to the upper end of the side wall portion, and a discharge hole (140) formed in the bottom portion (120);

[0100] It includes a residual discharge means for opening and closing the above discharge hole (140).

[0101] The overall shape of the above container body (100) can be various shapes such as cylindrical or square columnar, and there is no limitation on the material.

[0102] In addition, the above contents discharge part may have various structures depending on the type of contents or the method of use (for example, a spout part to which a pumping device or a lid is connected, a connector connection part provided for butane gas, or a nozzle provided for a spray, etc.).

[0103] In the drawings of this specification, it can be seen that an embodiment is representatively illustrated in which an upper spout portion (170) is provided to which a lid (170A) is coupled as a contents discharge portion.

[0104] As one of the core elements of the present invention, the residual discharge means is broadly classified into a plug-type as shown in Fig. 6 and a cock-type as shown in Fig. 7.

[0105] First, as an example of the present invention,

[0106] The above discharge hole (140) is formed as a lower spout (150) that protrudes from the lower surface of the bottom portion (120) and has screw threads formed on the outer surface,

[0107] The above residual discharge means is composed of a plug (160) that is connected to the lower spout (150).

[0108] The above lower spout portion (150) is formed by protruding downward from the center of the bottom portion (120) in a configuration applicable to general PET bottles, etc.

[0109] At this time, it is preferable that the bottom part (120) is formed to slope downward from the outer part toward the lower spout part (150) in the center.

[0110] Accordingly, the contents of the contents storage unit (110) flow down the slope of the bottom part (120) due to its own weight and are collected in the discharge hole (140) of the lower spout part (150). Therefore, when a small amount of contents remains, the remaining amount does not spread over the entire bottom part (120) but remains in the discharge hole (140) of the lower spout part (150).

[0111] In this way, the contents remaining in the discharge hole (140) of the lower spout (150) are easily discharged to the outside of the container body (100) when the stopper (160) is opened.

[0112] When the present invention is used as a pumping container, if the injection tube of the pumping device is assembled so that its lower end is positioned at the discharge hole (140) of the lower spout (150), the contents collected in the discharge hole (140) can be completely pumped out through the injection tube of the pumping device during pumping operation, which is convenient.

[0113] After use, the cap (160) can be opened to make it easier to clean the inside of the container body (100).

[0114] At this time, the present invention has the lower spout (150) protruding from the bottom surface of the bottom (120), so the container body (100) cannot be stored upright, so a lower cap (LC) was added.

[0115] The lower cap (LC) is detachably coupled to the lower end of the side wall portion (130) while covering the bottom portion (120).

[0116] This lower cap (LC) is formed in a form in which the side supports are vertically connected upward along the edge of the bottom support so that the upper surface is open, and is formed in a shape corresponding to the cross-sectional shape of the contents storage portion (110) and is connected to the lower end of the container body (100).

[0117] At this time, the method of combining the container body (100) and the lower cap (LC) can be performed in various ways.

[0118] For example, a method in which a lower cap (LC) is forcibly fitted to the lower side wall (130) of the container body (100) and the lower cap (LC) is forcibly separated when necessary.

[0119] Alternatively, a method may be considered in which corresponding screw threads are formed on the lower side wall portion (130) of the container body (100) and the side support portion of the lower cap (LC), and the connection and separation are achieved through screw connection.

[0120] Next, as another example of the present invention,

[0121] The above bottom part (120) has a dome shape convex upwards and has a discharge hole (140) perforated in the center of the top.

[0122] The above residual discharge means is configured as a safety cock (180) that is fitted into and connected to the discharge hole (140) and opens and closes the discharge hole (140) by lifting.

[0123] This embodiment is particularly applicable to metal containers in which gas type contents such as butane gas, spray, or pesticide are stored, and its purpose is to avoid separately drilling a hole in the container body (100) after use.

[0124] The above safety cock (180) can be applied in various known ways.

[0125] In the drawing of the present invention, a safety cock (180) is representatively illustrated, which includes a ram (1810) fitted into the discharge hole (140), a sealing portion (1820) protruding from the inner end of the ram (1810) to seal the discharge hole (140), and a spring (1830) that elastically supports the ram (1810) so that it is pulled out to the lower part of the container body (100).

[0126] At this time, the above-mentioned core (1810) has a length that protrudes to a height lower than the dome height of the bottom part (120).

[0127] Accordingly, after use, if the safety cock (180) is pressed to open the discharge hole (140), the remaining gas can be discharged to the outside by the gas pressure inside the container body (100), so that the user does not have to directly drill a separate hole in the container body (100), which is convenient.

[0128] In addition, the lower cap (LC) is provided to protect the safety cock (180) so as to prevent gas from leaking due to unintentional pressing of the safety cock (180).

[0129] Next, a modified example of Fig. 6 will be described with reference to Fig. 8.

[0130] The above container body (100) includes a sealing portion (190) that forms a fitting portion (1910) that protrudes from the bottom surface of the bottom portion (120) at a predetermined interval around the circumference of the lower spout portion (150) and into which the stopper (160) is fitted, and extends lower than the lower end of the lower spout portion (150) and has a hook protrusion (1920) formed at the lower end thereof.

[0131] The above plug (160) includes a mounting groove (1610) formed on the outer edge, and an O-ring (1620) fitted into the mounting groove (1610) but mounted so that a portion thereof protrudes outward.

[0132] When the plug (160) is combined with the lower spout (150), the hook projection (1920) presses the protrusion of the O-ring (1620) to ensure airtightness.

[0133] The above fitting portion (1910) has a shape corresponding to the side portion of the plug (160), and when the plug (160) is screw-connected to the lower spout portion (150), the upper portion of the side portion of the plug (160) is screw-connected by pushing the hook projection (1920) outward and causing it to open.

[0134] At this time, the hook protrusion (1920) is formed so that its inner tip is aligned with the height of the corner of the plug (160).

[0135] When the side portion of the plug (160) is fitted into the fitting portion (1910) and the screw connection is completed, the sealing portion (190) that was opened outward as the hook projection (19200) passes through the plug (160) is restored to its original shape, and the inner tip of the hook projection (1920) presses the protrusion of the O-ring (1620), thereby filling the gap between the lower spout portion (150) and the plug (160).

[0136] Accordingly, the gap between the lower spout (150) and the plug (160) forms a bypass path in the shape of a 'ㄷ', thereby preventing leakage of the contents, and even if a small amount of the contents is leaked, external leakage is prevented by the O-ring (1620).

[0137] In addition, FIG. 9 illustrates a third embodiment that is a mixture of the first and second embodiments.

[0138] Referring to Figure 9, the present invention

[0139] A container body (1000) in which a bottom powder (1200) having a residual quantity storage area formed at the bottom of a side wall (1300) is connected, and a cut portion (C1) is formed along the connection portion of the side wall (1300) and the bottom powder (1200).

[0140] It includes a lower cap (LC1) that is detachably coupled to the lower end of the side wall portion (1300) or the bottom powder (1200) to cover the bottom powder (1200).

[0141] The above container body (1000) can have various shapes such as cylindrical, elliptical, and square, but is limited to a circular shape when the bottom powder (1200) or lower cap (LC1) is connected by screw connection.

[0142] The container body (1000) is made of various plastic materials used in general household goods.

[0143] And the shape or structure of the upper part of the container body (1000) can be changed in various ways (for example, a pumping container shape, or a simple lid-attached container shape, etc.).

[0144] The above-mentioned bottom powder (1200) is connected to the side wall portion (1300) in a manner that can be cut or separated by an external force, and various methods can be considered for detaching the bottom powder (1200) from the side wall portion (1300) based on the cut portion (C1).

[0145] For example, the side wall portion (1300) and the bottom powder (1200) may be completely separated, and a tape (not shown) may be attached to the outer surface where the side wall portion (1300) and the bottom powder (1200) come into contact to be joined.

[0146] Or, the bottom powder (1200) may be screw-connected to the side wall (1300).

[0147] Alternatively, a method may be considered in which a cutting line is formed at the connection between the side wall (1300) and the bottom powder (1200), or the connection is formed very thinly and then forcibly cut by an external force.

[0148] The above-mentioned bottom powder (1200) is in the shape of a bowl and has a residual amount collecting portion formed inside it where the remaining amount of the contents can be collected.

[0149] Accordingly, if the contents of the container body (1000) are continued to be used in their original form, when the remaining amount remains at a height lower than the bottom powder (1200), the contents are collected and stored in the bottom powder (1200). Accordingly, if the bottom powder (1200) is separated from the side wall (1300) of the container body (1000), the remaining amount of the contents can be stored separately in the bottom powder (1200).

[0150] And at this time, the container body (1000) including the separated and removed side wall portion (1300) is washed and then separated and discharged.

[0151] The above lower cap (LC1) may be of any shape that can cover the bottom powder (1200), and there are no restrictions on its shape or method of joining.

[0152] In the drawing, an embodiment in which the lower cap (LC1) is tightly coupled to the bottom powder (1200) is representatively illustrated, but the present invention is not limited thereto.

[0153] And the way the lower cap (LC1) is joined is also

[0154] For example, the lower cap (LC1) is screw-connected to the lower outer surface of the side wall (1300) or the lower cap (LC1) is detachably screw-connected to the wall portion (121) of the bottom powder (1200).

[0155] Alternatively, a method in which the lower cap (LC1) is detachable by engaging with a projection and a groove on the side wall (1300) or the wall portion (121) of the bottom powder (1200) may be considered.

[0156] When the contents of the container body (1000) remain only in the bottom powder (1200), the bottom cap (LC1) can be separated first, the bottom powder (1200) can be separated from the container body (1000), and then the bottom cap (LC1) can be turned over to be used as a lid for the bottom powder (1200).

[0157] Various methods can also be considered for combining the lower cap (LC1) as a lid to the above-mentioned bottom powder (1200).

[0158] For example, a method of using the size difference between the bottom powder (1200) and the bottom cap (LC1) to flip the bottom cap (LC1) over and forcefully fit it to the bottom powder (1200).

[0159] Or, the bottom powder (1200) and the wall portion (LC1a) of the lower cap (LC1) are provided with screw threads that can be screw-connected to each other, so that the bottom cap (LC1) is screw-connected to the bottom powder (1200) in an upside-down state.

[0160] Alternatively, a method may be considered in which the bottom powder (1200) and the lower cap (LC1) are provided with protrusions and grooves that can be mutually combined, so that the lower cap (LC1) is combined with the bottom powder (1200) by the protrusions and grooves while turned over.

[0161] In this way, when using the lower cap (LC1) as a lid for the separated bottom powder (1200), there is no need to wash and throw away the remaining contents separately. After separating and discharging the main body of the container (1000), the contents of the bottom powder (1200) can be completely used when needed, and then the bottom powder (1200) and the lower cap (LC1) can be separated and discharged again.

[0162] This can help reduce costs by allowing for full use of the remaining contents without discarding them.

[0163] It enables separation and disposal of containers without leaving any contents inside, thereby reducing cleaning costs during recycling and providing environmentally friendly containers.

[0164] Meanwhile, the present invention is a modified example of Fig. 9, which adopts the double screw coupling structure of Fig. 10 to make the detachment of the bottom powder and the lower cap more convenient.

[0165] First, a first screw thread (1301) is provided on the lower outer surface of the side wall portion (1300).

[0166] The above-mentioned bottom powder (1200) has an outer wall portion (1201) and an inner wall portion (1202) that are installed inwardly and outwardly to form a detachable groove into which the lower end of the side wall portion (1300) is fitted, and includes a second screw thread (1201a) formed on the inner surface of the outer wall portion (1201) and screw-connected to the first screw thread (1301), a third screw thread (1202a) formed on the outer surface of the inner wall portion (1202), and a fourth screw thread (1203) extended and connected to the lower portion of the third screw thread (1202a).

[0167] The lower cap (LC1) is provided with a wall portion (LC1a) that can be inserted between the outer wall portion (1201) and the inner wall portion (1202), and includes a fifth screw thread (LC1c) formed on the inner surface of the wall portion (LC1a) and capable of being screw-connected to the third screw thread (1202a) or the fourth screw thread (1203).

[0168] The side wall portion (1300) and the wall portion (LC1a) have the same diameter, and the first screw thread (1301) is formed on the outer surface of the side wall portion (1300), and the fifth screw thread (LC1c) is formed on the inner surface of the wall portion (LC1a).

[0169] The above-mentioned bottom powder (1200) is connected in a form in which the inner wall (1202) is extended from the upper portion of the wall (LC1a) and the outer wall (1201) is spaced apart from the inner wall (1202) and branched, and the inner diameter of the outer wall (1201) has a size corresponding to the outer diameter of the side wall (1300), so that the second screw thread (1201a) is screw-connected to the first screw thread (1301), and the bottom powder (1200) is connected to the lower portion of the side wall (1300) to form the container body (1000).

[0170] And the bottom powder (1200) has the third screw thread (1202a) formed on the outer surface of the inner wall (1202), and the fourth screw thread (1203) formed on the outer surface of the wall (LC1a) below the portion connecting the outer wall (1201) and the inner wall (1202).

[0171] The third screw thread (1202a) and the fourth screw thread (1203) are made of the same standard, so that the fifth screw thread (LC1c) can be selectively screw-connected to the third screw thread (1202a) and the fourth screw thread (1203).

[0172] Accordingly, as the fifth screw thread (LC1c) of the bottom powder (1200) is screw-connected to the fourth screw thread (1203), the bottom powder (1200) forms the bottom of the container body (1000).

[0173] And when there is content left in the bottom powder (1200), the bottom powder (1200) is separated from the side wall (1300), and then the lower cap (LC1) is separated from the bottom powder (1200), and then the lower cap (LC1) is turned over and the fifth screw thread (LC1c) is screwed into the third screw thread (1202a) so that the lower cap (LC1) can be used as a lid for the bottom powder (1200).

[0174] In describing the present invention above, the container has been mainly described with reference to the attached drawings, but the present invention can be modified, changed and substituted in various ways by those skilled in the art, and such modifications, changes and substitutions should be interpreted as falling within the scope of protection of the present invention.
