Patent Description:
Among cosmetics, color cosmetics such as eyeshadows, shades, blushers, foundations, and the like are provided in the form of a compact container having an inner container for storing a cosmetic content and an outer container for fixing the inner container thereto. As the inner container and the outer container of the compact container are formed integrally with each other, it is impossible to separate them from each other, and otherwise, they are tightly coupled to each other by means of an adhesive or the like, it is hard to separate the inner container from the outer container. As a result, after the cosmetic content is used up, it is difficult that only the inner container is replaced with new one to allow the outer container to be reusable.

In the case where the inner container and the outer container of the compact container are made of different materials from each other, further, they are necessary to be separated from each other in a process where the compact container is thrown away. In the case of the conventional compact container, however, it is impossible to separate the inner container from the outer container, or even if possible, the remaining cosmetic material in the separation process may be applied dirtily to a hand. Further, nails may be damaged due to the separation process. As a result, such a separation process may cause many inconveniences.

Generally, the compact container is configured to have a container part in which a given content is stored and a covering part for opening and closing the container part. The covering part is rotatably coupled to one side of the container part, and a hinge pin made of a metal material is used to rotate the covering part. In this case, it is hard to separate only the hinge pin from the compact container made of a synthetic resin, thereby making it difficult to recycle the compact container. Document <CIT> discloses a container in accordance with the preamble of claim <NUM>.

Accordingly, to solve the above-mentioned problems occurring in the related art, it is an object of the present invention to provide a container that is capable of allowing a first container part in which a given content is stored to be fixed or easily separated from a second container part by means of simple rotations of a locking part.

The technical problems to be achieved through the present invention are not limited as mentioned above, and other technical problems not mentioned herein will be obviously understood by one of ordinary skill in the art through the following description.

To accomplish the above-mentioned objects, according to the present invention, there is provided a container. The container may include: a first container part for storing a given content therein; a second container part having couplers disposed on a top thereof in such a way as to surroundingly fix the outer peripheral surface of the first container part thereto; and a locking part rotatably coupled to the couplers in such a way as to surround the outer peripheral surfaces of the couplers, wherein each coupler has a pressurizer bent inward therefrom, if the locking part rotates in a first direction with respect to the couplers, to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto.

According to the present invention, the container is configured to allow the first container part in which the given content is stored to be fixed or easily separated from the second container part by means of the simple rotations of the locking part, so that only the first container part is replaced with new one, thereby allowing the container to be recyclable.

According to the present invention, further, the container is configured to allow the first container part to be easily separated and discharged from the second container part if the first container part and the second container part are made of different materials, thereby improving the conveniences of use.

According to the present invention, furthermore, the container is configured to allow the second container part and the covering part to be detachably fitted to each other, so that they are easily coupled to each other, without any hinge pin, thereby allowing the container to be recyclable.

According to the present invention, additionally, the container is configured to have at least a portion made of a transparent or semi-transparent material, so that the type, color, and remaining amount of the content stored therein to be easily checked by the user.

According to an embodiment of the present invention is provided a container. The container includes: a first container part for storing a given content therein; a second container part having couplers disposed on a top thereof in such a way as to surroundingly fix the outer peripheral surface of the first container part thereto; and a locking part rotatably coupled to the couplers in such a way as to surround the outer peripheral surfaces of the couplers, wherein each coupler has a pressurizer bent inward therefrom, if the locking part rotates in a first direction with respect to the couplers, to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto.

Further, if the locking part rotates in a second direction opposite to the first direction with respect to the couplers, the pressurizers return to original positions thereof to allow the pressurization against the first container part to be released, so that the first container part is separated from the couplers.

Furthermore, the locking part has guide portions protruding from the inner peripheral surface thereof and having slant surfaces formed in a horizontal direction on given regions thereof, and if the locking part rotates in the first direction, the pressurizers come into close contact with the slant surfaces and move relative to the locking part, so that the pressurizers are bent inward from the couplers.

Besides, the pressurizers extend by a given length in the second direction from tops of the couplers.

Moreover, the couplers include a first coupler and a second coupler spaced apart from each other to surround different regions of the outer peripheral surface of the first container part, and the pressurizers extend in the second direction from top of one side of the first coupler and from top of one side of the second coupler.

Further, if the guide portions of the locking part are inserted into spaces between the first coupler and the second coupler, the slant surfaces are aligned with positions corresponding to the pressurizers.

Furthermore, the locking part has at least one or more guide protrusions protruding from the inner peripheral surface thereof, and the couplers have at least one or more guide grooves concavely formed on the outer peripheral surfaces thereof in such a way as to correspond to the guide protrusions, so that if the locking part rotates, the guide protrusions move along the guide grooves to allow the locking part to rotate at a constant height.

Additionally, each guide groove extends from one point of the outer peripheral surface of the corresponding coupler to one point of the corresponding pressurizer in a circumferential direction.

Further, each coupler has a first locking projection formed on the bottom thereof, and each guide portion has a second locking projection protruding from the bottom of the slant surface thereof, so that if the locking part rotates in the first direction, the second locking projections of the locking part move under the pressurizers and come into contact with the end portions of the first locking projections to allow the locking part to be prevented from additionally rotating in the first direction.

Moreover, the locking part has locking protrusions formed on the inner peripheral surface of in such a way as to be spaced apart from the guide portions by a given distance, and the couplers have locking grooves formed on the outer peripheral surfaces of the first locking projections in such a way as to correspond to the locking protrusions, so that the locking protrusions are inserted into the locking grooves to allow the locking part to be prevented from arbitrarily rotating.

The container according to the present invention further includes a covering part detachably coupled to one side of the second container part in such a way as to rotate with respect to the second container part to open and close the second container part.

Further, the second container part has a first hinge recessed inward from one side thereof, and the covering part has a second hinge protruding from one side thereof in such a way as to be inserted into the first hinge, so that if the second hinge is inserted into the first hinge, the covering part is detachably coupled to the second container part.

Furthermore, the first hinge includes: an incised portion recessed inward from the second container part; and at least one or more hinge protrusions protruding inward from the incised portion, and the second hinge includes: a protruding portion protruding downward from the covering part; and at least one or more hinge grooves recessed inward from the protruding portion in such a way as to correspond to the hinge protrusions, whereby if the second hinge is inserted into the first hinge, the hinge protrusions are fittedly coupled to the hinge grooves to allow the covering part to be rotatable with respect to the second container part around the hinge protrusions.

Besides, the covering part has at least a portion made of a transparent or semi-transparent material so that the given content stored in the first container part is seen outside the container.

<FIG> is a perspective view showing a container according to an embodiment of the present invention, <FIG> is an exploded perspective view showing the container according to the embodiment of the present invention, and <FIG> is an exploded perspective view showing a second container part and a cover part of the container according to the embodiment of the present invention. In detail, <FIG> shows a state where a container is closed, and <FIG> shows a state where the container is open.

Referring to <FIG>, a container <NUM> according to an embodiment of the present invention includes a first container part <NUM>, a second container part <NUM>, a locking part <NUM>, and/or a covering part <NUM>.

The first container part <NUM> stores a given content therein. In this case, the given content is a solid, semi-solid, powder, liquid or gel cosmetic content. For example, the content may be a base, blusher, shade, eyeshadow, eyebrow, lotion, milk lotion, moisture lotion, nutrition lotion, skin lotion, skin softer, skin toner, astringent, massage cream, nutrition cream, whitening essence, tone-up cream, sunblock, sun cream, sun milk, BB cream, foundation, CC cream, concealer, eye cream, primer, and the like. However, the content may not be limited thereto, and therefore, the content may include different formulations or types of cosmetics or medicines.

For example, the first container part <NUM> has a circular, oval, or polygonal base surface and a peripheral surface extending upward from the base surface and is open on top thereof to form a storage space portion in which the content is stored. In detail, the first container part <NUM> has various shapes, such as a cylinder, a cone, a truncated cone, a semi-sphere, a polygonal column, a polygonal cone, and a polygonal truncated cone whose tops are open. In this case, the polygonal column, the polygonal cone, and the polygonal truncated cone have flat surfaces or curved surfaces with given curvatures.

Further, the first container part <NUM> has at least a portion made of a metal material such as aluminum, copper, titanium, magnesium, iron, and the like. However, of course, the first container part <NUM> may be made of a synthetic resin such as polypropylene (PP), polyethylene terephthalate (PET), polyethylene terephthalate glycol-modified (PETG), and the like or a natural material such as a fabric, paper, fibers, Tencel, silk, and the like.

The second container part <NUM> has a coupler <NUM> located on a top thereof to fix the first container part <NUM> thereto. The coupler <NUM> serves to surround the outer periphery of the first container part <NUM> and thus fix the first container part <NUM> thereto.

According to the embodiment of the present invention, the coupler <NUM> includes a pressurizer <NUM>, vertical grooves <NUM>, a guide groove <NUM>, a first locking projection <NUM> and/or a locking groove <NUM>.

The pressurizer <NUM> serves to fix the first container part <NUM> to the second container part <NUM> or separate the first container part <NUM> from the second container part <NUM> according to rotations of the locking part <NUM>.

For example, if the locking part <NUM> rotates in a first direction (e.g., in a clockwise direction) with respect to the coupler <NUM>, the pressurizer <NUM> is bent inward from the coupler <NUM> and pressurizes the outer peripheral surface of the first container part <NUM>, so that the first container part <NUM> is fixed to the second container part <NUM>. In <FIG>, the first direction represents the clockwise direction, but without being limited thereto, the first direction may represent a counterclockwise direction.

Further, for example, if the locking part <NUM> rotates in a second direction (e.g., in the counterclockwise direction) opposite to the first direction with respect to the coupler <NUM> in the state where the pressurizer <NUM> pressurizes the first container part <NUM>, the pressurizer <NUM>, which has been bent inward from the coupler <NUM>, returns to its original position. Accordingly, the pressurization of the pressurizer <NUM> against the first container part <NUM> is released, so that the first container part <NUM> is separated from the coupler <NUM>. If the content stored in the first container part <NUM> is all consumed, the first container part <NUM> is easily separated from the coupler <NUM> by means of the rotation of the locking part <NUM>, so that the first container part <NUM> is replaced with a new first container part <NUM>. Further, if the first container part <NUM> and the second container part <NUM> have different materials (for example, if the first container part <NUM> is made of an aluminum material and the second container part <NUM> is made of a plastic material), the first container part <NUM> is easily separated and discharged from the second container part <NUM>.

According to the embodiment of the present invention, the pressurizer <NUM> has at least a portion made of an elastic material so that it is bent inward from the coupler <NUM> or returns to its original position according to the rotational directions of the locking part <NUM>. However, the pressurizer <NUM> may not be limited thereto.

According to the embodiment of the present invention, the pressurizer <NUM> extends by a given length in the second direction on top of the coupler <NUM> (in detail, on top of one side surface of the coupler <NUM>). When the locking part <NUM> rotates in the first direction, the pressurizer <NUM> extending by the given length allows a relatively large area thereof to come into contact with the locking part <NUM> (especially, a slant surface <NUM>), receives a pressurizing force from the contact, and is thus easily bent inward from the coupler <NUM>.

The plurality of vertical grooves <NUM> are formed so that when the locking part <NUM> rotates, they serve to facilitate elastic deformation of the pressurizer <NUM>. For example, the vertical grooves <NUM> are spaced apart from one another along the inner surface of the pressurizer <NUM>. The elastic deformation of the pressurizer <NUM> is more easily made by means of the vertical grooves <NUM>, so that the pressurizer <NUM> comes into contact with the outer peripheral surface of the first container part <NUM> more tightly to pressurizingly fix the first container part <NUM> thereto.

Even if the size of the first container part <NUM> is changed within a given range, further, the pressurizer <NUM> is elastically deformed correspondingly to the size of the first container part <NUM> by means of the vertical grooves <NUM>. Irrespective of the size of the first container part <NUM>, that is, the pressurizer <NUM> can come into close contact with the outer peripheral surface of the first container part <NUM> to pressurizingly fix the first container part <NUM> thereto.

The guide groove <NUM> is concavely formed along the outer peripheral surface of the coupler <NUM>. The guide groove <NUM> serves to insert a guide protrusion <NUM> of the locking part <NUM> so that when the locking part <NUM> rotates with respect to the second container part <NUM>, the guide protrusion <NUM> moves along the guide groove <NUM>. That is, when the locking part <NUM> rotates, the rotational height of the locking part <NUM> is constantly kept by means of the guide groove <NUM> and the guide protrusion <NUM>.

According to the embodiment of the present invention, the guide groove <NUM> extends from one point of the outer peripheral surface of the coupler <NUM> to one point of the pressurizer <NUM> in a circumferential direction. As the guide groove <NUM> extends up to the outer peripheral surface of the pressurizer <NUM>, the locking part <NUM> rotates in the first or second direction more stably by means of the user, thereby allowing the first container part <NUM> to be coupled to or separated from the second container part <NUM>.

The first locking projection <NUM> is formed on the bottom of the coupler <NUM> and comes into contact with a second locking projection <NUM> of the locking part <NUM> rotating in the first direction to prevent the locking part <NUM> from additionally rotating in the first direction. For example, the pressurizer <NUM> extends in the second direction from top of one side surface of the coupler <NUM>, and the first locking projection <NUM> protrudes by a given length from the bottom (that is, under the pressurizer <NUM>) of one side surface of the coupler <NUM> where the pressurizer <NUM> is formed in the second direction.

The locking groove <NUM> is formed on the outer peripheral surface of the coupler <NUM>, and as a locking protrusion <NUM> of the locking part <NUM> is inserted into the locking groove <NUM>, the locking part <NUM> is prevented from arbitrarily rotating. For example, the locking groove <NUM> is formed on the outer peripheral surface of the first locking projection <NUM>, thereby preventing the locking part <NUM> from additionally rotating in the first direction by means of the first locking projection <NUM>, while preventing the locking part <NUM> from rotating in the first direction and arbitrarily rotating in the second direction by means of the locking groove <NUM>.

According to the embodiment of the present invention, a plurality of couplers <NUM> are provided to surround different regions of the outer peripheral surface of the first container part <NUM>. For example, a first coupler <NUM>-<NUM> and a second coupler <NUM>-<NUM> are provided as the couplers <NUM>. The first coupler <NUM>-<NUM> and the second coupler <NUM>-<NUM> are spaced apart from each other to surround different regions of the first container part <NUM>. In this case, the pressurizers <NUM> extend in the second direction from top of one side of the first coupler <NUM>-<NUM> and from top of one side of the second coupler <NUM>-<NUM>, and they pressurize the different regions of the outer peripheral surface of the first container part <NUM>, thereby fixing the first container part <NUM> thereto. Like this, as the plurality of regions (especially, the outer peripheral surfaces in opposite directions to each other) of the first container part <NUM> are pressurized and fixed, the first container part <NUM> is fixed to the couplers <NUM> more tightly. In <FIG> and <FIG>, two couplers <NUM> are provided, but without being limited thereto, three or more couplers <NUM> may be provided.

The second container part <NUM> has a first hinge <NUM> recessed on one side thereof. The first hinge <NUM> serves to insert the covering part <NUM> (especially a second hinge <NUM>), thereby allowing the second container part <NUM> to be detachably coupled to the covering part <NUM>.

According to the embodiment of the present invention, the first hinge <NUM> includes an incised portion <NUM> and at least one or more hinge protrusions <NUM>. The incised portion <NUM> is recessed inward from the second container part <NUM> and inserts a protruding portion <NUM> of the covering part <NUM> thereinto. Further, the hinge protrusions <NUM> protrude inward from the incised portion <NUM> and are inserted into hinge grooves <NUM> of the covering part <NUM>. For example, the hinge protrusions <NUM> protrude inward from the facing inner surfaces of the incised portion <NUM>.

According to the embodiment of the present invention, the second container part <NUM> is made of a recyclable material. The second container part <NUM> is made of a reusable material having no post processing, and therefore, the second container part <NUM> is eco-friendly. For example, the second container part <NUM> is made of polypropylene (PP), polyethylene terephthalate (PET), or polyethylene terephthalate glycol-modified (PETG). However, the second container part <NUM> may be made of other materials, without being limited thereto.

The locking part <NUM> rotates with respect to the couplers <NUM> to allow the first container part <NUM> to be fixed to or separated from the couplers <NUM>. To do this, the locking part <NUM> is rotatably coupled to the couplers <NUM> in such a way as to surround the outer peripheral surfaces of the couplers <NUM>.

According to the embodiment of the present invention, the locking part <NUM> includes guide portions <NUM>, the guide protrusions <NUM>, and the locking protrusions <NUM>.

The guide portions <NUM> protrude from the inner peripheral surface of the locking part <NUM> and allow the pressurizers <NUM> to be bent inward from the couplers <NUM> according to the rotation of the locking part <NUM>.

To do this, each guide portion <NUM> has the slant surface <NUM> formed in a horizontal direction on a given region thereof. For example, the slant surface <NUM> increases in a protruding height from the guide portion <NUM> in the second direction. If the locking part <NUM> rotates in the first direction, accordingly, the pressurizers <NUM> come into close contact with the slant surfaces <NUM> and move relative to the locking part <NUM>, so that they are bent inward from the couplers <NUM>.

According to the embodiment of the present invention, if the first coupler <NUM>-<NUM> and the second coupler <NUM>-<NUM> are provided as the couplers <NUM>, the guide portions <NUM> of the locking part <NUM> are alignedly inserted into spaces between the first coupler <NUM>-<NUM> and the second coupler <NUM>-<NUM>. To couple the locking part <NUM> to the couplers <NUM>, that is, the guide portions <NUM> of the locking part <NUM> are first aligned to be located above the spaces between the first coupler <NUM>-<NUM> and the second coupler <NUM>-<NUM>, and next, the locking part <NUM> moves down to allow the guide portions <NUM> to be inserted into the corresponding spaces. Accordingly, the slant surfaces <NUM> are aligned with positions and heights corresponding to the pressurizers <NUM>, and the guide protrusions <NUM> are aligned with positions corresponding to the guide grooves <NUM>, so that if the locking part <NUM> rotates, the second container part <NUM> and the locking part <NUM> are coupled to each other.

According to the embodiment of the present invention, each guide portion <NUM> has the second locking projection <NUM> protruding from the underside of the slant surface <NUM>. The second locking projection <NUM> comes into contact with the end portion of the first locking projection <NUM> of each coupler <NUM>, thereby limiting the movement of the locking part <NUM> rotating in the first direction. In detail, if the locking part <NUM> rotates in the first direction, the second locking projection <NUM> moves under the corresponding pressurizer <NUM> and comes into contact with the end portion of the first locking projection <NUM>, thereby preventing the locking part <NUM> from additionally rotating in the first direction. To do this, for example, the pressurizer <NUM> extends in the second direction from top of one side surface of the coupler <NUM>, the first locking projection <NUM> protrudes from the bottom of the coupler <NUM>, and the second locking projection <NUM> extends in the first direction.

The guide protrusion <NUM> protrudes from the inner peripheral surface of the locking part <NUM> so that it is inserted into the guide groove <NUM> of the coupler <NUM>, if the locking part <NUM> rotates, and moves along the guide groove <NUM>. For example, the guide protrusion <NUM> extends by a given length in a horizontal direction (or in the rotating direction of the locking part <NUM>). While the locking part <NUM> is rotating in the first direction, the pressurizer <NUM> is bent inward from the coupler <NUM> and thus generates an external force (that is, an elastic restoring force of the pressurizer <NUM>), and even under such an external force, the locking part <NUM> rotates to a given height, without escaping from the coupler <NUM>.

The locking protrusion <NUM> is inserted into the locking groove <NUM> of the coupler <NUM>, thereby preventing the locking part <NUM> from arbitrarily rotating. If an external force greater than a given size in the second direction is applied to the locking part <NUM> in the state where the locking protrusion <NUM> is inserted into the locking groove <NUM>, the locking protrusion <NUM> escapes from the locking groove <NUM>, thereby allowing the locking part <NUM> to rotate in the second direction. For example, the locking protrusion <NUM> is formed on the inner peripheral surface of the locking part <NUM> in such a way as to be spaced apart from the guide portion <NUM> by a given distance, and the locking groove <NUM> is formed on the outer peripheral surface of the first locking projection <NUM> in such a way as to correspond to the locking protrusion <NUM>. In this case, if the locking part <NUM> rotates in the first direction to allow the second locking projection <NUM> to come into contact with the end portion of the first locking projection <NUM>, the locking protrusion <NUM> can be inserted into the locking groove <NUM>.

The covering part <NUM> is detachably coupled to one side of the second container part <NUM> in such a way as to rotate with respect to the second container part <NUM> to open and close the second container part <NUM>. To do this, the covering part <NUM> has the second hinge <NUM> protruding therefrom in such a way as to correspond to the first hinge <NUM> of the second container part <NUM>. That is, as the second hinge <NUM> is inserted into the first hinge <NUM>, the covering part <NUM> is detachably coupled to the second container part <NUM>. Accordingly, the covering part <NUM> is simply fitted to the second container part <NUM>, without having any existing hinge pin used to rotatably couple the container and the cover to each other.

According to the embodiment of the present invention, the second hinge <NUM> includes the protruding portion <NUM> protruding downward therefrom and at least one or more hinge grooves <NUM> recessed inward from the protruding portion <NUM>. For example, if the plurality of hinge protrusions <NUM> protrude inward from the facing inner surfaces of the incised portion <NUM>, the plurality of hinge grooves <NUM> are recessed inward from both sides of the protruding portion <NUM> in such a way as to correspond to the hinge protrusions <NUM>. As the second hinge <NUM> is inserted into the first hinge <NUM>, the hinge protrusions <NUM> are fittedly coupled to the hinge grooves <NUM>, so that the covering part <NUM> is rotatable with respect to the second container part <NUM> around the hinge protrusions <NUM>.

According to the embodiment of the present invention, an open portion <NUM> is formed on an open region of the hinge groove <NUM>. The open portion <NUM> extends downward from at least a portion of the open region of the hinge groove <NUM> and thus forms a path for inserting the hinge protrusion <NUM> when the second hinge <NUM> is coupled to the first hinge <NUM>. That is, if the second container part <NUM> and the covering part <NUM> are coupled to each other to allow the second hinge <NUM> to be inserted into the first hinge <NUM>, the hinge protrusions <NUM> are easily inserted into the hinge grooves <NUM> by means of the open portions <NUM>. Further, for example, the open portions <NUM> increase in width toward the lower sides thereof. As a result, the hinge protrusions <NUM> are more easily inserted into the hinge grooves <NUM>, and after the insertion, they are prevented from escaping from the hinge grooves <NUM>.

According to the embodiment of the present invention, the covering part <NUM> has at least a portion made of a transparent or semi-transparent material. As a result, the content stored in the first container part <NUM> is seen outside of the container <NUM>, thereby allowing the type, color, and remaining amount of the content to be checked by the user. For example, at least a portion of the covering part <NUM> is made of polypropylene (PP), polyethylene terephthalate (PET), or polyethylene terephthalate glycol-modified (PETG), which is the same material as the second container part <NUM>. However, the covering part <NUM> may be made of a different material from the second container part <NUM>, without being limited thereto.

The container <NUM> as shown in <FIG> is just exemplary, and therefore, the container <NUM> may have various configurations according to embodiments of the present invention.

<FIG> show operations of the container according to the embodiment of the present invention. In detail, <FIG> and <FIG> are perspective and plan views showing the container <NUM> where the first container part <NUM> is removed. <FIG> and <FIG> show states where the pressurization of the pressurizers <NUM> against the first container part <NUM> is released, and <FIG> and <FIG> show states where the first container part <NUM> is pressurizedly fixed to the pressurizers <NUM>. Further, <FIG> shows a state where the first container part <NUM> is pressurized against the pressurizers <NUM>, and <FIG> shows a state where the first container part <NUM> is separated from the second container part <NUM>.

Referring first to <FIG> and <FIG>, if the locking part <NUM> rotates in the first direction with respect to the couplers <NUM>, the pressurizers <NUM> move relative to the locking part <NUM> and thus come into contact with the slant surfaces <NUM> of the guide portions <NUM>, so that they are bent inward from the couplers <NUM>. As a result, the pressurizers <NUM> pressurize the outer peripheral surface of the first container part <NUM> to allow the first container part <NUM> to be fixed to the second container part <NUM>.

Further, the second locking projections <NUM> of the locking part <NUM> move in the first direction under the pressurizers <NUM> and come into contact with the end portions of the first locking projections <NUM>, so that the locking part <NUM> is prevented from additionally rotating in the first direction. In this case, the locking protrusions <NUM> of the locking part <NUM> are inserted into the locking grooves <NUM> of the couplers <NUM>, so that the locking part <NUM> is prevented from arbitrarily rotating in the first and second directions.

Referring to <FIG>, furthermore, if the locking part <NUM> rotates in the second direction in the state where the pressurizers <NUM> pressurize the first container part <NUM>, the pressurizers <NUM>, which have been bent inward from the couplers <NUM>, return to their original position. As a result, the pressurization of the pressurizers <NUM> against the first container part <NUM> is released to allow the first container part <NUM> to be separated from the couplers <NUM>.

The operations of the container <NUM> as shown in <FIG> are just exemplary, and therefore, the operations of the container <NUM> may be freely performed according to embodiments of the present invention.
